The National Heart Foundation of Australia has updated the Guide to management of hypertension 2008: assessing and managing raised blood pressure in adults (updated December 2010). Main recommendations For patients at low absolute cardiovascular disease risk with persistent blood pressure (BP) ≥ 160/100 mmHg, start antihypertensive therapy. The decision to treat at lower BP levels should consider absolute cardiovascular disease risk and/or evidence of end-organ damage, together with accurate BP assessment. For patients at moderate absolute cardiovascular disease risk with persistent systolic BP ≥ 140 mmHg and/or diastolic BP ≥ 90 mmHg, start antihypertensive therapy. Treat patients with uncomplicated hypertension to a target BP of < 140/90 mmHg or lower if tolerated. Changes in management as a result of the guideline Ambulatory and/or home BP monitoring should be offered if clinic BP is ≥ 140/90 mmHg, as out-of-clinic BP is a stronger predictor of outcome. In selected high cardiovascular risk populations, aiming for a target of < 120 mmHg systolic can improve cardiovascular…

This guideline summary describes the fourth edition of Acute pain management: scientific evidence, which was published by the Australian and New Zealand College of Anaesthetists (ANZCA) and its Faculty of Pain Medicine (FPMANZCA) in December 2015. The fourth edition summarises the best available evidence on acute pain management, following methods established over the preceding three editions. It provides additional information by scoring the quality of and reporting further details on randomised controlled trials and meta-analyses. The information is condensed into key messages that provide: concise statements on each topic, showing the highest level of evidence; and clinical practice points based on clinical experience or expert opinion.

There has been substantial reform in the past decade in the provision of maternal and child health services, and specifically regarding models of maternity care. Increasingly, midwives are working together in small groups to provide midwife-led continuity of care. This article reviews the current evidence for models of maternity care that provide midwifery continuity of care, in terms of their impact on clinical outcomes, the views of midwives and childbearing women, and health service costs. A systematic review of midwife-led continuity of care models identified benefits for women and babies, with no adverse effects. Non-randomised studies have shown benefits of midwifery continuity of care for specific groups, such as Aboriginal and Torres Strait Islander women. There are also benefits for midwives, including high levels of job satisfaction and less occupational burnout. Implementing midwifery continuity of care in public and private settings in Australia has been challenging, despite the evidence in its favour and government policy documents that support it. A reorganisation of…

INTRODUCTION: The modern care of suspected and confirmed acute coronary syndrome (ACS) is informed by an extensive and evolving evidence base. This clinical practice guideline focuses on key components of management associated with improved clinical outcomes for patients with chest pain or ACS. These are presented as recommendations that have been graded on both the strength of evidence and the likely absolute benefit versus harm. Additional considerations influencing the delivery of specific therapies and management strategies are presented as practice points. MAIN RECOMMENDATIONS: This guideline provides advice on the standardised assessment and management of patients with suspected ACS, including the implementation of clinical assessment pathways and subsequent functional and anatomical testing. It provides guidance on the: diagnosis and risk stratification of ACS; provision of acute reperfusion therapy and immediate post-fibrinolysis care for patients with ST segment elevation myocardial infarction; risk stratification informing the use of routine versus selective invasive…

OBJECTIVE: We explored the relationship between the National Emergency Access Target (NEAT) compliance rate, defined as the proportion of patients admitted or discharged from emergency departments (EDs) within 4 hours of presentation, and the risk-adjusted in-hospital mortality of patients admitted to hospital acutely from EDs. DESIGN, SETTING AND PARTICIPANTS: Retrospective observational study of all de-identified episodes of care involving patients who presented acutely to the EDs of 59 Australian hospitals between 1 July 2010 and 30 June 2014. MAIN OUTCOME MEASURE: The relationship between the risk-adjusted mortality of inpatients admitted acutely from EDs (the emergency hospital standardised mortality ratio [eHSMR]: the ratio of the numbers of observed to expected deaths) and NEAT compliance rates for all presenting patients (total NEAT) and admitted patients (admitted NEAT). RESULTS: ED and inpatient data were aggregated for 12.5 million ED episodes of care and 11.6 million inpatient episodes of care. A highly significant (P < 0.001) linear, inverse relationship between eHSMR…

OBJECTIVE: To implement a statewide program for the early recognition and treatment of sepsis in New South Wales, Australia. SETTING: Ninety-seven emergency departments in NSW hospitals. INTERVENTION: A quality improvement program (SEPSIS KILLS) that promoted intervention within 60 minutes of recognition, including taking of blood cultures, measuring serum lactate levels, administration of intravenous antibiotics, and fluid resuscitation. MAIN OUTCOME MEASURES: Time to antibiotics and fluid resuscitation; mortality rates and length of stay. RESULTS: Data for 13 567 patients were entered into the database. The proportion of patients receiving intravenous antibiotics within 60 minutes of triage increased from 29.3% in 2009-2011 to 52.2% in 2013. The percentage for whom a second litre of fluid was started within 60 minutes rose from 10.6% to 27.5% (each P < 0.001). The proportion of patients classed as Australasian Triage Scale (ATS) 1 increased from 2.3% in 2009-2011 to 4.2% in 2013, and the proportion classed as ATS 2 rose from 40.7% in 2009-2011 to 60.7% in 2013 (P < 0.001). There…

INTRODUCTION: This article, Part 1 of the Endocrine Society of Australia's position statement on male hypogonadism, focuses on assessment of male hypogonadism, including the indications for testosterone therapy. (Part 2 will deal with treatment and therapeutic considerations.) MAIN RECOMMENDATIONS: Key points and recommendations are:Pathological hypogonadism arises due to diseases of the hypothalamus or pituitary gland (hypogonadotropic hypogonadism) or testes (hypergonadotropic hypogonadism). It is a clinical diagnosis with a pathological basis, confirmed by hormone assays.Hormonal assessment is based on measurement of circulating testosterone, luteinising hormone (LH) and follicle-stimulating hormone (FSH) concentrations. Measurement of sex hormone-binding globulin levels can be informative, but use of calculated free testosterone is not recommended for clinical decision making.Testosterone replacement therapy is warranted in men with pathological hypogonadism, regardless of age.Currently, there are limited data from high-quality randomised controlled trials with clinically…

About 9% of Australians aged 65 years and over have a diagnosis of dementia. Clinical practice guidelines aim to enhance research translation by synthesising recent evidence for health and aged care professionals. New clinical practice guidelines and principles of care for people with dementia detail the optimal diagnosis and management in community, residential and hospital settings. The guidelines have been approved by the National Health and Medical Research Council. The guidelines emphasise timely diagnosis; living well with dementia and delaying functional decline; managing symptoms through training staff in how to provide person-centred care and using non-pharmacological approaches in the first instance; and training and supporting families and carers to provide care.

OBJECTIVES: To report age-standardised rates and methods of suicide by health professionals, and to compare these with suicide rates for other occupations. STUDY DESIGN: Retrospective mortality study. SETTING, PARTICIPANTS: All intentional self-harm cases recorded by the National Coronial Information System during the period 2001-2012 were initially included. Cases were excluded if the person was unemployed at the time of death, if their employment status was unknown or occupational information was missing, or if they were under 20 years of age at the time of death. Suicide rates were calculated using Australian Bureau of Statistics population-level data from the 2006 census. MAIN OUTCOME MEASURES: Suicide rates and method of suicide by occupational group. RESULTS: Suicide rates for female health professionals were higher than for women in other occupations (medical practitioners: incidence rate ratio [IRR], 2.52; 95% CI, 1.55-4.09; P < 0.001; nurses and midwives: IRR, 2.65; 95% CI, 2.22-3.15; P < 0.001). Suicide rates for male medical practitioners were not significantly higher…

The well established disparities in health outcomes between Indigenous and non-Indigenous Australians include a significant and concerning higher incidence of preterm birth, low birth weight and newborn mortality. Chronic diseases (eg, diabetes, hypertension, cardiovascular and renal disease) that are prevalent in Indigenous Australian adults have their genesis in utero and in early life. Applying interventions during pregnancy and early life that aim to improve maternal and infant health is likely to have long lasting consequences, as recognised by Australia's National Maternity Services Plan (NMSP), which set out a 5-year vision for 2010-2015 that was endorsed by all governments (federal and state and territory). We report on the actions targeting Indigenous women, and the progress that has been achieved in three priority areas: The Indigenous maternity workforce; Culturally competent maternity care; and; Developing dedicated programs for "Birthing on Country". The timeframe for the NMSP has expired without notable results in these priority areas. More urgent leadership is…

The incidence of type 2 diabetes is increasing in Australia's older adult population. Sarcopenia, the age-related decline in skeletal muscle mass, quality and function, may make a significant but under-appreciated contribution to increasing the risk of type 2 diabetes. As skeletal muscle is the largest insulin-sensitive tissue in the body, low muscle mass in sarcopenia likely results in reduced capacity for glucose disposal. Age-related declines in muscle quality, including increased mitochondrial dysfunction and fat infiltration, are also implicated in skeletal muscle inflammation and subsequent insulin resistance. Prospective studies have shown that low muscle mass and strength are associated with increased risk of incident type 2 diabetes. Prevalent type 2 diabetes also appears to exacerbate progression of sarcopenia in older adults. Recently developed operational definitions and the inclusion of sarcopenia in the International classification of diseases, 10th revision, clinical modification, provide impetus for clinicians to diagnose and treat sarcopenia in older patients.…

Chronic hepatitis C virus (HCV) infection affects 230 000 Australians, who are at risk of progressive liver fibrosis leading to cirrhosis, liver failure and hepatocellular carcinoma. HCV infection is curable, and all Australians living with HCV should be considered for antiviral therapy. Interferon-free regimens involving combinations of sofosbuvir, ledipasvir, daclatasvir and/or ribavirin for 8, 12 or 24 weeks are now listed on the Pharmaceutical Benefits Scheme (PBS) for treating people with genotypes 1-3 HCV. Treatment for genotypes 4-6 HCV involves sofosbuvir plus peginterferon-alfa and ribavirin for 12 weeks. The PBS listing allows these therapies to be prescribed by specialists experienced in treating chronic HCV infection or by general practitioners in consultation with one of these specialists. People with cirrhosis and other special populations (eg, those with decompensated liver disease or renal impairment) should be referred for specialist care. Key issues during pre-treatment assessment include identifying HCV genotype, evaluating for cirrhosis and considering…

Helicobacter pylori infection is a major cause of morbidity and mortality worldwide. More than 50% of the global population is estimated to be infected. Differences in prevalence exist within and between countries, with higher prevalence seen among people with lower socio-economic status. Most transmission of infection occurs early in life, predominantly from person to person in the family setting. H. pylori is the cause of most peptic ulcer disease, gastric cancer and gastric mucosa-associated lymphoid tissue (MALT) lymphoma and causes symptoms in a subset of patients with functional dyspepsia. Choice of diagnostic test depends on the clinical context; urea breath tests and endoscopy with biopsy are the major diagnostic tools. Evidence-based indications for eradication of H. pylori infection are well documented. The most widely used and recommended eradication therapy in Australia is triple therapy comprising a proton pump inhibitor, amoxycillin and clarithromycin, usually for 1 week. Effective alternative regimens are available for patients with proven allergy to penicillin.…

OBJECTIVE: To quantify absolute cardiovascular disease (CVD) risk and treatment in Australian adults. DESIGN, PARTICIPANTS: Cross-sectional representative study of 9564 people aged 18 years or more who had participated in the 2011-12 Australian National Health Measures Survey (response rate for those aged 45-74 years: 46.5%). MAIN OUTCOME MEASURES: Prior CVD was ascertained and 5-year absolute risk of a primary CVD event calculated (using the Australian National Vascular Disease Prevention Alliance algorithm; categories: low [< 10%], moderate [10-15%], and high [> 15%] risk) on the basis of data on medical history, risk factors and medications, derived from interviews, physical measurements, and blood and urine samples. RESULTS: Absolute CVD risk increased with age and was higher among men than women. Overall, 19.9% (95% CI, 18.5-21.3%) of Australians aged 45-74 years had a high absolute risk of a future CVD event (an estimated 1 445 000 people): 8.7% (95% CI, 7.8-9.6%) had prior CVD (estimated 634 000 people) and 11.2% (95% CI, 10.2-12.2%) had high primary CVD risk (estimated 811…

Serum thyroid-stimulating hormone (TSH) testing is the best screening tool for thyroid dysfunction. When TSH levels are in the reference range, additional tests such as free thyroxine, free triiodothyronine or thyroid antibodies rarely add value, except in patients with pituitary disease, when TSH is unreliable. Overt hypothyroidism and subclinical hypothyroidism with TSH levels > 10 mU/L can be treated without further investigation. The health impact of subclinical hypothyroidism with mildly elevated levels of TSH (4-10 mU/L) remains uncertain, particularly in older people; treatment or observation are reasonable options. Thyroxine remains standard treatment for hypothyroidism, with optimal dosage determined by clinical response and serum TSH. Hyperthyroidism is commonly caused by Graves' disease, thyroiditis or toxic nodular goitre. The cause should be established before offering treatment. Radionuclide scanning is the imaging modality of choice. Positive TSH-receptor antibodies indicate Graves' disease. Thyroid ultrasound is indicated for assessment of palpable goitre and thyroid…

OBJECTIVES: To examine geographic and demographic trends in objection to vaccination in Australia. DESIGN: Cross-sectional analysis of Australian Childhood Immunisation Register (ACIR) data (2002-2013) for children aged 1-6 years. MAIN OUTCOME MEASURES: Immunisation status according to whether an objection had been registered, and remoteness and socio-economic status of area of residence. Registration of children with Medicare after 12 months of age was used as a proxy indicator of being overseas-born. RESULTS: The proportion of children affected by a registered vaccination objection increased from 1.1% in 2002 to 2.0% in 2013. Children with a registered objection were clustered in regional areas. The proportion was lower among children living in areas in the lowest decile of socio-economic status (1.1%) than in areas in the highest socio-economic decile (1.9%). The proportion not affected by a recorded objection but who were only partly vaccinated for vaccines due at 2, 4 and 6 months of age was higher among those in the lowest decile (5.0% v 3.4%), suggesting problems of access to…

OBJECTIVE: To estimate the number of regular and dependent methamphetamine users in Australia. DESIGN: Indirect prevalence estimates were made for each year from 2002-03 to 2013-14. We applied multiplier methods to data on treatment episodes for amphetamines (eg, counselling, rehabilitation, detoxification) and amphetamine-related hospitalisations to estimate the numbers of regular (at least monthly) and dependent methamphetamine users for each year. Dependent users comprised a subgroup of those who used the drug regularly, so that estimates of the sizes of these two populations were not additive. RESULTS: We estimated that during 2013-14 there were 268 000 regular methamphetamine users (95% CI, 187 000-385 000) and 160 000 dependent users (95% CI, 110 000-232 000) aged 15-54 years in Australia. This equated to population rates of 2.09% (95% CI, 1.45-3.00%) for regular and 1.24% (95% CI, 0.85-1.81%) for dependent use. The rate of dependent use had increased since 2009-10 (when the rate was estimated to be 0.74%), and was higher than the previous peak (1.22% in 2006-07). The highest…

OBJECTIVE: To investigate associations between general practitioner vocational training location and subsequent practice location, including the effect of rural origin. DESIGN AND PARTICIPANTS: Annual panel survey of GPs (from the MABEL study) who completed their vocational training and transitioned to independent practice, 2008-2014. MAIN OUTCOME MEASURES: Rural practice location in the 5 years after vocational registration for participants in four primary cohorts: (1) rural origin/rural training; (2) metropolitan origin/rural training; (3) rural origin/metropolitan training; and (4) metropolitan origin/metropolitan training. RESULTS: During the study period, 610 doctors completed GP vocational training and commenced independent practice. 74-91% of rural origin/rural training cohort GPs remained in rural areas during their first 5 years after completing training, with 61-70% remaining in the same community. Conversely, 87-95% of metropolitan origin/metropolitan training cohort GPs remained in metropolitan areas. GPs from the other two cohorts initially remained in their training…

Coal workers' pneumoconiosis (CWP) is an untreatable but preventable lung disease arising from chronic inhalation of coal dust. Recent reports of CWP in Queensland, along with international data, suggest that there is a resurgence in pneumoconiosis. The prevalence of CWP varies considerably between countries. In Australia, there is no mandatory reporting system and no national data on the prevalence of CWP. The symptoms and manifestations of CWP vary depending on the composition of the inhaled dust, duration of exposure, stage of disease and host-related factors. CWP may develop into progressive massive fibrosis (PMF), which can be fatal. Radiological assessment should be performed according to evidence-based standards using the ILO (International Labour Office) International Classification of Radiographs of Pneumoconioses. As preventing exposure to coal dust prevents CWP, it is important to implement and enforce appropriate standards limiting exposure. In Australia, these standards currently vary between states and are not in keeping with international understanding of the levels…

The provision of timely, relevant and reliable information on patient care to clinicians has been shown to drive improvements in health care quality. Well constructed clinical quality registries collect and report information on both the appropriateness of care (process) in keeping with clinical practice guidelines and the effectiveness of care (outcomes). Notwithstanding the successful establishment of several new registries and improvements in established registries, barriers persist for clinical groups wishing to improve the quality of information and level of participation in registries in Australia. To address these barriers, the Australian Commission on Safety and Quality in Health Care has developed the Framework for Australian Clinical Quality Registries. The Framework describes a mechanism by which government jurisdictions and private hospital groups can authorise and secure record-level data, within high priority clinical domains, to measure, monitor and report the appropriateness and effectiveness of health care. The provision of benchmarked information back to clinicians…

OBJECTIVE: Hospital and laboratory data indicate that human T-lymphotropic virus type 1 (HTLV-1) is endemic to central Australia, but no community-based studies of its prevalence or disease burden have been reported. We determined the prevalence rates of HTLV-1 infection and of HTLV-1-associated diseases in a remote Indigenous community. SETTING: A remote Northern Territory community. DESIGN: All residents were asked to complete a health survey and offered a limited clinical examination, together with serological tests for HTLV-1 and Strongyloides, and HTLV-1 proviral load (PVL) assessment. MAIN OUTCOME MEASURES: HTLV-1 seropositivity rates; HTLV-1 PVL (copies/105 peripheral blood leucocytes [PBL]); presentation with HTLV-1-related clinical disease. RESULTS: HTLV-1 serostatus was determined for 97 of 138 residents (70%). The prevalence of HTLV-1 infection was significantly higher among adults (30 of 74 people tested) than children (1 of 23; P = 0.001). Nine of 30 HTLV-1-positive adults had a clinical syndrome that was potentially attributable to HTLV-1 infection (chronic lung…

OBJECTIVES: To investigate the effects of intensive acute hospital physiotherapy for patients with isolated hip fractures. DESIGN, SETTING: Single-institution, prospective, randomised trial at a level 1 trauma centre in Melbourne, March 2014 - January 2015. PARTICIPANTS: 92 patients aged 65 years or more with isolated hip fractures. Patients were excluded if the fracture was subtrochanteric or pathological, or if post-operative orders required the patient to be non-weight-bearing on the operated leg. INTERVENTIONS: Randomisation to usual care physiotherapy (daily; control group) or intensive physiotherapy (three times daily; intervention group). MAIN OUTCOME MEASURES: Outcomes were assessed at post-operative Day 5, at discharge, and at 6 months. The primary outcome was the modified Iowa Level of Assistance (mILOA) score, with other outcome measures including Timed Up and Go test performance and hospital length of stay (LOS). RESULTS: After controlling for sex, anaesthetic type and home setting, the between-group difference in Day 5 mILOA score favoured the intervention group (mean…

OBJECTIVES: The Australian National Cervical Screening Program (NCSP) will transition in 2017 from cytology-based screening every two years, starting from age 18-20 years, to HPV-based screening every 5 years, starting from age 25. To examine the impact of the program before this transition we analysed trends in the incidence of cervical cancer, by age and histological subtype. DESIGN, SETTING AND PARTICIPANTS: National cervical cancer incidence data, 1982-2010. MAIN OUTCOME MEASURES: Standardised rate ratios (SRR) for 3-yearly average cervical cancer incidence, relative to the rate during 1988-1990, by age group and histological type. RESULTS: Between 1988-1990 and 2008-2010, cervical cancer incidence fell substantially in women aged 25-49 (SRR, 0.55; 95% CI, 0.51-0.59), 50-69 (SRR, 0.46; 95% CI, 0.42-0.51) and 70 years or more (SRR, 0.50; 95% CI, 0.43-0.58), but not in women aged 20-24 years (SRR, 0.70; 95% CI, 0.46-1.05). These declines were primarily driven by drops in squamous cell carcinoma (SCC) in women aged 25-49 (SRR, 0.50; 95% CI, 0.46-0.55), 50-69 (SRR, 0.39; 95% CI,…

The role of consumers is now extending beyond being passive health care recipients and even active participants in their own care to involvement in innovation and value co-creation in health care - from being "users and choosers" to becoming "makers and shapers" of services. For active dialogue to occur in co-creation, consumers must become equal partners with health care organisations and providers, with the focus on areas of interest to all parties. The use of value co-creation in health care involves embedding the approach across the whole health care system - from the microsystem level to the mesosystem and the entire macrosystem.

INTRODUCTION: Part 1 of this position statement dealt with the assessment of male hypogonadism, including the indications for testosterone therapy. This article, Part 2, focuses on treatment and therapeutic considerations for male hypogonadism and identifies key questions for future research. MAIN RECOMMENDATIONS: Key points and recommendations are:Excess cardiovascular events have been reported in some but not all studies of older men without pathological hypogonadism who were given testosterone treatment. Additional studies are needed to clarify whether testosterone therapy influences cardiovascular risk.Testosterone is the native hormone that should be replaced in men being treated for pathological hypogonadism. Convenient and cost-effective treatment modalities include depot intramuscular injection and transdermal administration (gel, cream or liquid formulations).Monitoring of testosterone therapy is recommended for efficacy and safety, focusing on ameliorating symptoms, restoring virilisation, avoiding polycythaemia and maintaining or improving bone mineral density.Treatment…

OBJECTIVE: To compare contemporary pregnancy outcomes in women with and without type 1 diabetes, and to examine the effects of obesity and glycaemic control on these outcomes. DESIGN AND SETTING: Historical cohort study in a specialist diabetes and maternity network in Victoria. PARTICIPANTS: All singleton births (at least 20 weeks' gestation), 2010-2013, were analysed: 107 pregnancies to women with type 1 diabetes and 27 075 pregnancies to women without diabetes. Women with type 2 diabetes or gestational diabetes were excluded. METHODS: Data were extracted from the Birthing Outcomes System database; associations between type 1 diabetes and pregnancy outcomes were analysed by multivariable regression. MAIN OUTCOME MEASURES: Mode of birth; maternal and neonatal outcomes. RESULTS: The mean body mass index was higher for women with type 1 diabetes than for women without diabetes (mean, 27.3 kg/m(2) [SD, 5.0] v 25.7 kg/m(2) [SD, 5.9]; P = 0.01); the median gestation period for their babies was shorter (median, 37.3 weeks [IQR, 34.6-38.1] v 39.4 weeks [IQR, 38.4-40.4]; P < 0.001) and…

OBJECTIVE: To determine the source and extent of a locally acquired hepatitis E virus (HEV) infection outbreak. DESIGN, SETTING AND PARTICIPANTS: A cluster of notified cases of HEV infection linked to a single restaurant (X) was identified in May 2014. People with laboratory-confirmed HEV infection in New South Wales between January 2013 and December 2014 were interviewed about potential risk factors for HEV infection. Co-diners at restaurant X and patients with suspected but unexplained viral hepatitis were retrospectively tested. Foods eaten by the infected persons were compared with those of seronegative co-diners. HEV RNA detected in sera from infected persons was sequenced and genotyped. Implicated foods were traced back to their sources. MAIN OUTCOME MEASURES: Potential sources of infection, including overseas travel and foods eaten, and origin of implicated food products. RESULTS: In 55 serologically confirmed cases of HEV infection, 24 people had not travelled overseas during their incubation periods. Of the 24, 17 reported having eaten at restaurant X, 15 of whom could be…

OBJECTIVE: The primary aim of the NSW Heart Failure (HF) Snapshot was to obtain a representative cross-sectional view of patients with acute HF and their management in New South Wales and Australian Capital Territory hospitals. DESIGN AND SETTING: A prospective audit of consecutive patients admitted to 24 participating hospitals in NSW and the ACT with a diagnosis of acute HF was conducted from 8 July 2013 to 8 August 2013. RESULTS: A total of 811 participants were recruited (mean age, 77 ± 13 years; 58% were men; 42% had a left ventricular ejection fraction ≥ 50%). The median Charlson Comorbidity Index score was 3, with ischaemic heart disease (56%), renal disease (55%), diabetes (38%) and chronic lung disease (32%) the most frequent comorbidities; 71% of patients were assessed as frail. Intercurrent infection (22%), non-adherence to prescribed medication (5%) or to dietary or fluid restrictions (16%), and atrial fibrillation/flutter (15%) were the most commonly identified precipitants of HF. Initial treatment included intravenous diuretics (81%), oxygen therapy (87%), and bimodal…

Chronic non-cancer pain (lasting more than 3 months) is highly prevalent in Australia (17% of males and 20% of females) and its optimal management is crucial to the health and wellbeing of the community. For 5% of the population, such pain interferes markedly with daily function. Part of the treatment for acute non-cancer pain for many people will include opioid analgesics at least for days to weeks. However, as pain becomes chronic, evidence to support ongoing prescription of opioids is lacking. There is increasing pressure to ensure that prescribing opioid analgesics is minimised to reduce not only the risk of dependence and illicit diversion but also the potential harms associated with tolerance, side effects and complications. Frameworks for considering opioid prescribing include assessing suitability of the patient for opioids; initiating a trial of therapy; and monitoring long term use. There is limited evidence of the long term efficacy of opioids for chronic non-cancer pain, and documented clinical consequences beyond addiction include acceleration of loss of bone mineral…

OBJECTIVE: To investigate how doctors define and use the terms "futility" and "futile treatment" in end-of-life care. DESIGN, SETTING, PARTICIPANTS: A qualitative study using semi-structured interviews with 96 doctors from a range of specialties which treat adults at the end of life. Doctors were recruited from three large Brisbane teaching hospitals and were interviewed between May and July 2013. RESULTS: Doctors' conceptions of futility focused on the quality and prospect of patient benefit. Aspects of benefit included physiological effect, weighing benefits and burdens, and quantity and quality of life. Quality and length of life were linked, but many doctors discussed instances in which benefit was determined by quality of life alone. Most described assessing the prospects of achieving patient benefit as a subjective exercise. Despite a broad conceptual consensus about what futility means, doctors noted variability in how the concept was applied in clinical decision making. More than half the doctors also identified treatment that is futile but nevertheless justified, such as…

OBJECTIVE: To assess factors associated with second-line delays in the management of patients diagnosed with lung cancer. DESIGN, SETTING AND PARTICIPANTS: A retrospective cohort study, conducted in six public and two private Victorian hospitals, of 1417 patients aged 18 years or more who were diagnosed between July 2011 and October 2014 with an incident case of lung cancer identified by International Classification of Diseases, 10th revision codes (C34.0-C34.9, Z85.1, Z85.2) on the basis of either a clinical or pathological diagnosis. OUTCOME MEASURES: Time intervals between referral, diagnosis and initial definitive management. RESULTS: The median time from referral to diagnosis was 15 days (interquartile range [IQR], 5-36); from diagnosis to initial definitive management, 30 days (IQR, 6-84); and from referral to initial definitive management, 53 days (IQR, 25-106). Factors that were significantly associated with delay between referral and initial definitive management include declining or not being referred to palliative care (hazard ratio [HR], v patients referred for…

Patients diagnosed with breast cancer may have supportive care needs for many years after diagnosis. High quality multidisciplinary care can help address these needs and reduce the physical and psychological effects of breast cancer and its treatment. Ovarian suppression and extended endocrine therapy benefits are associated with vasomotor, musculoskeletal, sexual and bone density-related side effects. Aromatase inhibitor musculoskeletal syndrome is a common reason for treatment discontinuation. Treatment strategies include education, exercise, simple analgesia and a change to tamoxifen or another aromatase inhibitor. Chemotherapy-induced alopecia may be a constant reminder of breast cancer to the patient, family, friends, acquaintances and even strangers. Alopecia can be prevented in some patients using scalp-cooling technology applied at the time of chemotherapy infusion. The adverse impact of breast cancer diagnosis and treatment on sexual wellbeing is under-reported. Identification of physical and psychological impacts is needed for implementation of treatment strategies. Fear…

Maturity onset diabetes of the young (MODY), the most common monogenic form of diabetes, accounts for 1-2% of all diabetes diagnoses. Glucokinase (GCK)-MODY (also referred to as MODY2) constitutes 10-60% of all MODY cases and is inherited as an autosomal dominant heterozygous mutation, resulting in loss of function of the GCK gene. Patients with GCK-MODY generally have mild, fasting hyperglycaemia that is present from birth, are commonly leaner and diagnosed at a younger age than patients with type 2 diabetes, and rarely develop complications from diabetes. Hence, treatment is usually unnecessary and may be ceased. Therefore, genetic screening is recommended in all young patients (< 40 years) with an autosomal dominant family history of diabetes and who lack features of the metabolic syndrome and type 1 diabetes. Further, treatment discontinuation should be discussed with the patient as part of the informed consent process, as the realisation that prior treatment may have not been necessary - or that it could have been less burdensome - may have psychological implications for the…

Osteoporosis affects 1.2 million Australians and, in 2012, fractures due to osteoporosis and osteopenia in Australians aged over 50 years cost $2.75 billion. Even minor minimal trauma fractures are associated with increased morbidity and mortality. Despite increasing therapeutic options for managing osteoporosis, fewer than 20% of patients with a minimal trauma fracture are treated or investigated for osteoporosis, so under-treatment is extremely common. Fracture risk assessment is important for selecting patients who require specific anti-osteoporosis therapy. Post-menopausal osteoporosis is frequently due to an imbalance in bone remodelling, with bone resorption exceeding bone formation. Antiresorptive drugs reduce the number, activity and lifespan of osteoclasts, and include bisphosphonates, oestrogen, selective oestrogen receptor-modulating drugs, strontium ranelate, and the human monoclonal antibody denosumab.

OBJECTIVES: In 2017, the National Cervical Screening Program in Australia will transition to 5-yearly primary HPV screening for all women, irrespective of human papillomavirus (HPV) vaccination status. As an adjunct to the mainstream program, HPV testing on self-collected samples will be offered under practitioner supervision to all unscreened and underscreened women aged 30-74 years. We quantified how different screening decisions affect the future risk of cervical cancer. DESIGN: Simulation of outcomes for 100 000 previously unscreened women, aged 30 years and eligible for self-collection, using a well-established model of HPV natural history and cervical screening. MAIN OUTCOME MEASURES: Cumulative cancer diagnoses and deaths averted (compared with remaining unscreened) to age 84, number needed to treat for pre-cancer (NNT) to avert each cancer diagnosis. RESULTS: One round of self-collected HPV screening at age 30 years would avert 908 cancer diagnoses and 364 cancer deaths in the cohort by age 84 (NNT, 5.8). Benefits would still be achieved were self-collected screening delayed…

As has been reported previously in the Journal, 1 novel psychoactive stimulant drugs are now increasingly prevalent in patients presenting to hospital emergency departments. A further cluster of 11 patients showing confusing hallmarks of sympathomimetic poisoning but no identifiable substance presented to St Vincent ’ s Hospital in Sydney over a public holiday weekend in April 2015. Also, the start to the 2015 e 2016 summer festival season has included multiple deaths and hospitalisations following drug use at festivals, leading to calls for novel actions to protect public health. 2 Here, we take the opportunity to describe a method of harm minimisation that has been deployed in Europe and could potentially be deployed locally to tackle this problem.

[Extract] Developments in genomic science are disproportionately in advance of their translational clinical application. Multidisciplinary clinics are proposed to overcome this1 in many medical fields.2 This is especially so in nephrology, which is typified by significant community disease burden3 and heritability.4 Several renal genetics clinics (RGCs) operate overseas, although their models and outcomes are largely unreported. The first multidisciplinary RGC in Australasia commenced at the Royal Brisbane and Women's Hospital in August 2013, involving a clinical geneticist, nephrologist, genetic counsellor, and ancillary clinical and diagnostic services. The departments of clinical genetics and nephrology jointly operate the RGC. The clinical geneticist and nephrologist see families in the same appointment, maximising use of time. In this article, we report this clinical service's initial outcomes and model for mainstreaming genetic medicine.

OBJECTIVES: To determine the nature, prevalence and description accuracy of recorded antibiotic allergy labels (AALs) in a cohort of general medical inpatients, and to assess the feasibility of an oral antibiotic re-challenge study. DESIGN: Multicentre cross-sectional study. SETTING AND PARTICIPANTS: All patients admitted to the general medical units of Austin Health and Alfred Health, 18 May - 5 June 2015. MAIN OUTCOME MEASURES: Baseline demographics, medical and allergy history, infection diagnoses and antibiotic prescribing data for general medical inpatients were collected. A questionnaire was administered to clarify AAL history, followed by correlation of responses with electronic and admissions record descriptions. A hypothetical oral re-challenge in a supervised setting was offered to patients with low risk allergy phenotypes (non-immediate reaction, non-severe cutaneous adverse reaction, or unknown reaction more than 10 years ago). RESULTS: Of the 453 inpatients, 107 (24%) had an AAL (median age, 82 years; interquartile range, 74-87 years); 160 individual AALs were recorded,…

OBJECTIVE: Australia has the highest incidence of colorectal cancer (CRC) in the world. The incidence of young-onset CRC (yCRC) is increasing in developed nations. Our aim was to determine the incidence of yCRC in New South Wales, the demographic and clinico-pathological characteristics of these patients, and their survival. DESIGN, SETTING, PARTICIPANTS: A population-based cohort study of all cases of CRC diagnosed in NSW during 2001-2008. Data on newly diagnosed cases of CRC were obtained from the NSW Central Cancer Registry; mortality data were obtained from the NSW Registry of Births Deaths and Marriages (to 2012). The characteristics and tumour-related factors of patients under 50 years of age (yCRC) were compared with those for patients aged 50 years or more. MAIN OUTCOME MEASURES: Current incidence of yCRC and trends in incidence; 5-year cancer-specific survival rates and risks of death compared with older patients. RESULTS: 32 178 patients were diagnosed with CRC, including 2001 (6.2%) with yCRC. The incidence of yCRC was unchanged across the study period (2001, 13.7 cases…

OBJECTIVES: To review evidence for the increased incidence of late diagnosed developmental dysplasia of the hip (DDH) in South Australia; to identify perinatal risk factors associated with late DDH in babies born between 2003 and 2009 in SA. DESIGN: Linkage study of data collected prospectively by the South Australian Birth Defects Register (SABDR) and the Pregnancy Outcome Statistics Unit (SA Department of Health), supplemented by medical records review. PARTICIPANTS: All children born 2003-2009 in whom DDH was diagnosed between 3 months and 5 years of age and notified to the SABDR (data inclusion range, 2003-2014). Children with teratological hip dislocations and other major congenital abnormalities were excluded. MAIN OUTCOME MEASURES: Uni- and multivariable analyses were performed to identify perinatal risk factors for late diagnosed DDH. RESULTS: The incidence of late diagnosed DDH in babies born 2003-2009 was 0.77 per 1000 live births, contrasting with the figure of 0.22 per 1000 live births during 1988-2003. Significant perinatal risk factors were birth in a rural hospital (v…

There is no convincing evidence that classic Lyme disease occurs in Australia, nor is there evidence that the causative agent, Borrelia burgdorferi, is found in Australian animals or ticks. Lyme disease, however, can be acquired overseas but diagnosed in Australia; most people presenting with laboratory-confirmed Lyme disease in Australia were infected in Europe. Despite the lack of evidence that Lyme disease can be acquired in Australia, growing numbers of patients, their supporters, and some politicians demand diagnoses and treatment according to the protocols of the "chronic Lyme disease" school of thought. Antibiotic therapy for chronic "Lyme disease-like illness" can cause harm to both the individual (eg, cannula-related intravenous sepsis) and the broader community (increased antimicrobial resistance rates). Until there is strong evidence from well performed clinical studies that bacteria present in Australia cause a chronic debilitating illness that responds to prolonged antibiotics, treating patients with "Lyme disease-like illness" with prolonged antibiotic therapy is…

OBJECTIVE: The study assessed longitudinal changes in the presentation of dental fluorosis and evaluated the impact of fluorosis on the perception of oral health among young adults. DESIGN AND SETTING: Prospective follow-up study during 2011-12 of a population-based study in South Australia conducted between 2003 and 2004. PARTICIPANTS: 8-13-year-old children initially examined in 2003 and 2004. MAIN OUTCOMES: Dental fluorosis was assessed with the Thylstrup and Fejerskov (TF) Index. The impact on perceptions of oral health by the study participants and their parents was assessed with the Global Rating of Oral Health (GROH). Pairwise comparative analysis of the presentation of fluorosis was conducted at the individual and tooth levels. Multivariable models of changes in fluorosis were generated. An ordinal logistic regression model was used to evaluate the association between GROH with dental fluorosis, caries and other factors. RESULT: A total of 314 participants completed the follow-up questionnaires and dental examination. Over 60% of teeth scored as TF 1 at baseline were scored…

Geographic variation in health care use has been demonstrated in many countries over many years. Such variation can be warranted - in response to patient need or preference for care - or unwarranted. Unwarranted variation raises concerns about equity and appropriateness of care. Recent analyses of health care provision in the Australian atlas of healthcare variation show that when routinely available Australian data are mapped by residence of patient, there are wide variations in rates of use of diagnostic tests, dispensing of prescriptions for a range of indications, surgical procedures and hospital admission rates. Despite the wealth of studies demonstrating variation in care internationally, there is relatively little research that explores the best ways of responding to unwarranted variation. Recommendations for action in the Australian Atlas focus on some approaches that could be used in Australia.

OBJECTIVES: To systematically review the evidence on whether statin therapy, commonly used in clinical practice to treat hypercholesterolaemia for primary and secondary prevention of cardiovascular disease, contributes to tendinopathy; and to examine causality according to the Bradford Hill criteria. STUDY DESIGN: A systematic review of studies examining the relationship between statin therapy and tendinopathy. Included studies were rated based on their methodological quality. A best evidence synthesis was used to summarise the results, and Bradford Hill criteria were used to assess causation. DATA SOURCES: Ovid MEDLINE, CINAHL Plus, PubMed and Embase databases. STUDY SELECTION: We included adult human studies published in the English language between January 1966 and October 2015. Study designs eligible for inclusion were randomised controlled trials and cross-sectional, cohort or case-control studies. DATA SYNTHESIS: Four studies (three cohort studies and one case-control study) were included, with a mean methodological quality score of 67%. Three studies were deemed high quality.…
