Stages of Valvular Heart Disease Among Older Adults in the Community: The Atherosclerosis Risk in Communities Study.

BACKGROUND: Limited data exist on American College of Cardiology/American Heart Association valvular heart disease (VHD) stage prevalence, progression, and association with incident cardiovascular diseases in late life. METHODS: Participants in the ARIC study (Atherosclerosis Risk in Communities), a prospective community-based cohort study, underwent protocol echocardiography at ARIC visits 5 (2011-2013) and 7 (2018-2019), and their aortic stenosis, aortic regurgitation, mitral stenosis, and mitral regurgitation stage were defined according to American College of Cardiology/American Heart Association guidelines. The overall VHD stage prevalence at visit 5 was measured. The associations between VHD stages and incident adjudicated death, heart failure, coronary heart disease, stroke, and atrial fibrillation were assessed with Cox proportional hazard models adjusted for age, sex, race, hypertension, diabetes, prior myocardial infarction, heart failure, body mass index, study center, systolic blood pressure, estimated glomerular filtration rate, and low-density lipoprotein at visit 5. Longitudinal changes in VHD stage prevalence over ≈6 years were estimated with inverse probability of attrition weights to account for participant attrition. RESULTS: Among 6118 ARIC participants, the mean±SD age was 76±5 years, 42% were male, and 22% reported Black race. Stage A VHD was present in 39%, stage B in 17%, and stage C/D in 1.1%;, 0.7% had previously undergone valve replacement or repair. A graded association was observed between stage A, B, and C/D VHD and risk of all-cause mortality, incident heart failure, incident atrial fibrillation, and incident coronary heart disease, but not incident stroke. Similar findings were observed for stages of each valvular lesion individually. During the 6.6 years (interquartile range, 6.1-7.0 years) between visits 5 and 7 (mean age, 81±4 years), the prevalence of freedom from VHD stage decreased from 43% to 24%, whereas the prevalence of stage C/D VHD increased from 1% to 7%. CONCLUSIONS: Subclinical VHD is common in older adults, with 39% at risk (stage A) and 17% with progressive VHD (stage B), and is independently associated with risk of incident cardiovascular events. VHD stages progress over 6 years in late life, with a several-fold increase in prevalence of severe VHD (stage C/D), highlighting the public health importance of interventions to mitigate VHD progression.

Clinical practice guidelines on the management of status epilepticus in adults: A systematic review.

OBJECTIVE: Status epilepticus (SE) is the second most common neurological emergency in adults. Despite improvements in the management of acute neurological conditions over the last decade, mortality is still durably high. Because a gap has emerged between SE management based on clinical practice guidelines (CPGs) and actual clinical practice, we conducted a systematic review of CPGs, assessing their quality, outlining commonalities and discrepancies in recommendations, and highlighting research gaps. METHODS: We searched the PubMed and EMBASE databases and other gray literature sources (nine among guideline registries, evidence-based medicine databases, point-of-care tools; seven websites of governmental organizations and international neurologic societies) in December 2021 (updated in November 2023). The units of analysis were CPGs that included recommendations on the diagnostic and/or therapeutic management of SE in adults. The quality of the CPGs was assessed using the AGREE II tool. RESULTS: Fifteen CPGs were included. The "Applicability" domain was assigned the lowest median score of 10%. The domains "Stakeholder Involvement", "Rigor of Development," and "Editorial Independence" were as well generally underrated. Recommendations on general and diagnostic management and on organizational interventions were fragmented and scattered. Recommendations on pre-hospital and hospital treatment of early-onset and refractory SE were broadly agreed, whereas there was less agreement on the treatment model and medications for established SE and super-refractory SE. SIGNIFICANCE: The CPGs for the management of SE developed in recent years are flawed by several methodological issues and discrepancies in the coverage of important topics. The gap between CPG-based management of SE and actual clinical practice may be due in part to the inherent limitations of the CPGs produced so far.

Designing tailored maintenance strategies for systematic reviews and clinical practice guidelines using the Portfolio Maintenance by Test-Treatment (POMBYTT) framework.

BACKGROUND: Organizations face diverse contexts and requirements when updating and maintaining their portfolio, or pool, of systematic reviews or clinical practice guidelines they need to manage. We aimed to develop a comprehensive, theoretical framework that might enable the design and tailoring of maintenance strategies for portfolios containing systematic reviews and guidelines. METHODS: We employed a conceptual approach combined with a literature review. Components of the diagnostic test-treatment pathway used in clinical healthcare were transferred to develop a framework specifically for systematic review and guideline portfolio maintenance strategies. RESULTS: We developed the Portfolio Maintenance by Test-Treatment (POMBYTT) framework comprising diagnosis, staging, management, and monitoring components. To illustrate the framework's components and their elements, we provided examples from both a clinical healthcare test-treatment pathway and a clinical practice guideline maintenance scenario. Additionally, our literature review provided possible examples for the elements in the framework, such as detection variables, detection tests, and detection thresholds. We furthermore provide three example strategies using the framework, of which one was based on living recommendations strategies. CONCLUSIONS: The developed framework might support the design of maintenance strategies that could contain multiple options besides updating to manage a portfolio (e.g. withdrawing and archiving), even in the absence of the target condition. By making different choices for variables, tests, test protocols, indications, management options, and monitoring, organizations might tailor their maintenance strategy to suit specific contexts and needs. The framework's elements could potentially aid in the design by being explicit about the operational aspects of maintenance strategies. This might also be helpful for end-users and other stakeholders of systematic reviews and clinical practice guidelines.

National Health and Medical Research Council statement on electronic cigarettes: 2022 update.

INTRODUCTION: Electronic cigarette (e-cigarette) use in Australia has rapidly increased since the 2017 National Health and Medical Research Council (NHMRC) Chief Executive Officer (CEO) statement on e-cigarettes. The type of products available and the demographic characteristics of people using these products have changed. New evidence has been published and there is growing concern among public health professionals about the increased use, particularly among young people who do not currently smoke combustible cigarettes. The combination of these issues led NHMRC to review the current evidence and provide an updated statement on e-cigarettes. In this article, we describe the comprehensive process used to review the evidence and develop the 2022 NHMRC CEO statement on electronic cigarettes. MAIN RECOMMENDATIONS: E-cigarettes can be harmful; all e-cigarette users are exposed to chemicals and toxins that have the potential to cause adverse health effects. There are no health benefits of using e-cigarettes if you do not currently smoke tobacco cigarettes. Adolescents are more likely to try e-cigarettes if they are exposed to e-cigarettes on social media. Short term e-cigarette use may help some smokers to quit who have been previously unsuccessful with other smoking cessation aids. There are other proven safe and effective options available to help smokers to quit. CHANGES IN MANAGEMENT AS A RESULT OF THIS STATEMENT: The evidence base for the harms of e-cigarette use has strengthened since the previous NHMRC statement. Significant gaps in the evidence base remain, especially about the longer term health harms of using e-cigarettes and the toxicity of many chemicals in e-cigarettes inhaled as an aerosol.

Cough in Children and Adults: Diagnosis, Assessment and Management (CICADA). Summary of an updated position statement on chronic cough in Australia.

INTRODUCTION: Cough is the most common symptom leading to medical consultation. Chronic cough results in significant health care costs, impairs quality of life, and may indicate the presence of a serious underlying condition. Here, we present a summary of an updated position statement on cough management in the clinical consultation. MAIN RECOMMENDATIONS: Assessment of children and adults requires a focused history of chronic cough to identify any red flag cough pointers that may indicate an underlying disease. Further assessment with examination should include a chest x-ray and spirometry (when age > 6 years). Separate paediatric and adult diagnostic management algorithms should be followed. Management of the underlying condition(s) should follow specific disease guidelines, as well as address adverse environmental exposures and patient/carer concerns. First Nations adults and children should be considered a high risk group. The full statement from the Thoracic Society of Australia and New Zealand and Lung Foundation Australia for managing chronic cough is available at https://lungfoundation.com.au/resources/cicada-full-position-statement. CHANGES IN MANAGEMENT AS A RESULT OF THIS STATEMENT: Algorithms for assessment and diagnosis of adult and paediatric chronic cough are recommended. High quality evidence supports the use of child-specific chronic cough management algorithms to improve clinical outcomes, but none exist in adults. Red flags that indicate serious underlying conditions requiring investigation or referral should be identified. Early and effective treatment of chronic wet/productive cough in children is critical. Culturally specific strategies for facilitating the management of chronic cough in First Nations populations should be adopted. If the chronic cough does not resolve or is unexplained, the patient should be referred to a respiratory specialist or cough clinic.

A summary of the 2023 Society of Obstetric Medicine of Australia and New Zealand (SOMANZ) hypertension in pregnancy guideline.

INTRODUCTION: Hypertensive disorders of pregnancy (HDP) affect up to 10% of all pregnancies annually and are associated with an increased risk of maternal and fetal morbidity and mortality. This guideline represents an update of the Society of Obstetric Medicine of Australia and New Zealand (SOMANZ) guidelines for the management of hypertensive disorders of pregnancy 2014 and has been approved by the National Health and Medical Research Council (NHMRC) under section 14A of the National Health and Medical Research Council Act 1992. In approving the guideline recommendations, NHMRC considers that the guideline meets NHMRC's standard for clinical practice guidelines. MAIN RECOMMENDATIONS: A total of 39 recommendations on screening, preventing, diagnosing and managing HDP, especially preeclampsia, are presented in this guideline. Recommendations are presented as either evidence-based recommendations or practice points. Evidence-based recommendations are presented with the strength of recommendation and quality of evidence. Practice points were generated where there was inadequate evidence to develop specific recommendations and are based on the expertise of the working group. CHANGES IN MANAGEMENT RESULTING FROM THE GUIDELINE: This version of the SOMANZ guideline was developed in an academically robust and rigorous manner and includes recommendations on the use of combined first trimester screening to identify women at risk of developing preeclampsia, 14 pharmacological and two non-pharmacological preventive interventions, clinical use of angiogenic biomarkers and the long term care of women who experience HDP. The guideline also includes six multilingual patient infographics which can be accessed through the main website of the guideline. All measures were taken to ensure that this guideline is applicable and relevant to clinicians and multicultural women in regional and metropolitan settings in Australia and New Zealand.

Real-world treatment of metastatic hormone-sensitive prostate cancer in the USA, Europe and Asia.

Aim: To characterize real-world patients with metastatic hormone-sensitive prostate cancer (mHSPC) and treating physicians and evaluate treatment trends and baseline concordance versus guidelines internationally. Materials & methods: Retrospective, cross-sectional data from the Ipsos Global Oncology Monitor database 2018-2020 were used for descriptive analysis of mHSPC patients, treating physicians and treatment utilization. Results: Among the 6198 mHSPC patients from five countries, the most common treatment was either androgen deprivation therapy (ADT) monotherapy or first-generation androgen receptor inhibitor + ADT. Second-generation androgen receptor inhibitor use was only initiating but increasing over the study period. Conclusion: Despite contemporaneous guidelines recommending treatment intensification of ADT in combination with novel antihormonals or docetaxel, 76.1% of reported mHSPC patients received non-guideline-concordant care.

Prostate cancer is the second most common cancer among men worldwide and a leading cause of cancer-related death globally. Metastatic hormone-sensitive prostate cancer (mHSPC) refers to the stage of prostate cancer where it has spread to other parts of the body ('metastatic') but still responds to hormonal therapy ('hormone-sensitive'), such as androgen deprivation therapy (ADT). Treatment guidelines around the world for men with mHSPC have changed over time, but there remains a lack of understanding of how well guidelines are followed in real-world practice. Consequently, this study analyzes real-world data from five countries between 2018 and 2020 to understand treatment patterns, baseline concordance versus guidelines and potential drivers of treatment trends. The study found prevalent use of ADT monotherapy and older antihormonal agents, and only marginal but increasing use of novel antihormonals in real-world practice. These practices deviate from guidelines from the study period, which generally recommended ADT combination with either newer antihormonal agents or docetaxel for patients with mHSPC. Overall, the proportion of the 6198 patients treated with non­guideline-concordant therapies was 76.1%. Since guideline-recommended care is associated with better outcomes, this baselining finding highlights the need for appropriate treatment selection and intensification for mHSPC patients.

Methodological quality and clinical recommendations of guidelines on the management of dyslipidaemias for cardiovascular disease risk reduction: a systematic review and an appraisal through AGREE II and AGREE REX tools.

BACKGROUND: Clinical practice guidelines (CPGs) are statements to assist practitioners and stakeholders in decisions about healthcare. Low methodological quality guidelines may prejudice decision-making and negatively affect clinical outcomes in non-communicable diseases, such as cardiovascular diseases worsted by poor lipid management. We appraised the quality of CPGs on dyslipidemia management and synthesized the most updated pharmacological recommendations. METHODS: A systematic review following international recommendations was performed. Searches to retrieve CPG on pharmacological treatments in adults with dyslipidaemia were conducted in PubMed, Scopus, and Trip databases. Eligible articles were assessed using AGREE II (methodological quality) and AGREE-REX (recommendation excellence) tools. Descriptive statistics were used to summarize data. The most updated guidelines (published after 2019) had their recommendations qualitatively synthesized in an exploratory analysis. RESULTS: Overall, 66 guidelines authored by professional societies (75%) and targeting clinicians as primary users were selected. The AGREE II domains Scope and Purpose (89%) and Clarity of Presentation (97%), and the AGREE-REX item Clinical Applicability (77.0%) obtained the highest values. Conversely, guidelines were methodologically poorly performed/documented (46%) and scarcely provided data on the implementability of practical recommendations (38%). Recommendations on pharmacological treatments are overall similar, with slight differences concerning the use of supplements and the availability of drugs. CONCLUSION: High-quality dyslipidaemia CPG, especially outside North America and Europe, and strictly addressing evidence synthesis, appraisal, and recommendations are needed, especially to guide primary care decisions. CPG developers should consider stakeholders' values and preferences and adapt existing statements to individual populations and healthcare systems to ensure successful implementation interventions.

Controversies in terminology associated with management of BCG-unresponsive NMIBC in Asia-Pacific.

OBJECTIVES: Examine the understanding of terminologies and management patterns of bacillus Calmette-Guérin (BCG)-unresponsive nonmuscle invasive bladder cancer (NMIBC) in six territories in Asia-Pacific. METHODS: This study involved two phases: (1) a survey with 32 urologists and 7 medical oncologists (MOs) and (2) a factorial experiment and in-depth interviews with 23 urologists and 2 MOs. All clinicians had ≥8 years' experience managing NMIBC patients in Australia, Hong Kong, Japan, South Korea, Singapore, and Taiwan. Data from Phase 1 were summarized using descriptive statistics; content and thematic analyses applied in Phase 2. RESULTS: In phase 1, 35% of clinicians defined BCG-unresponsive as BCG-refractory, -relapse and -resistant, 6% defined it as BCG-refractory and -relapse; 22% classified BCG-failure as BCG-refractory, -relapse, -resistant, and when muscle-invasive bladder cancer is detected. If eligible and willing, 50% (interquartile range [IQR], 50%-80%) of BCG-unresponsive patients would undergo radical cystectomy (RC), and 50% (IQR 20%-50%) of RC-eligible patients would receive bladder-sparing treatment or surveillance. In phase 2, we found that 32%, 88%, and 48% of clinicians, respectively, used "BCG-unresponsive," "BCG-refractory," and "BCG-relapse" in clinical practice but with no consistent interpretation of the terms. Compared with EAU definitions, 8%-60% of clinicians appropriately classified 9 tumor types that are persistent or recurrent after adequate BCG. Fifty percent of clinicians mentioned a lack of bladder-preserving treatment that outperforms RC in quality of life as a reason to retreat BCG-unresponsive patients with BCG. CONCLUSIONS: Our study revealed varied understanding and application of BCG-unresponsive terminologies in practice. There is a need for a uniform and simple definition of BCG-unresponsive disease in Asia-Pacific.

Endoscopic management of sinonasal tumours in the Nordic university hospitals: a survey.

PURPOSE: The Nordic countries (27 M) all have comparable, publicly funded healthcare systems, and the management of sinonasal tumours is centralised to the 21 university hospitals. We sought to assess and compare the treatment practice of sinonasal tumours across the Nordic countries. METHODS: A web-based questionnaire was sent to all university hospital departments of otorhinolaryngology-head and neck surgery in the Nordic countries. RESULTS: Answers were obtained from all 21 Nordic university hospitals. The endoscopic approach was widely utilised by all, with most (62%) centres reporting 3-4 surgeons performing endoscopic sinonasal tumour surgery. Finland reported the lowest rates of centralisation among university hospitals despite having the highest number of 0.1-1 M catchment population hospitals. Most centres (88%) opted for the endoscopic approach in a patient case warranting medial maxillectomy. In a case of a Kadish C esthesioneuroblastoma, most (52%) of the centres preferred an endoscopic approach. Most centres (62%) reported favouring the endoscopic approach in a case describing a juvenile angiofibroma. Regarding a case describing a sinonasal undifferentiated carcinoma, consensus was tied (38% vs. 38%) between endoscopic resection followed by postoperative (chemo)radiotherapy (RT/CRT) and induction chemotherapy followed by RT/CRT or surgery followed by RT/CRT. CONCLUSION: Endoscopic approach was widely utilised in the Nordic countries. The case-based replies showed differences in treatment practice, both internationally and nationally. The rate of centralisation among university hospitals remains relatively low, despite the rarity of these tumours.

Long-Term Leisure-Time Physical Activity Intensity and All-Cause and Cause-Specific Mortality: A Prospective Cohort of US Adults.

BACKGROUND: The 2018 physical activity guidelines for Americans recommend a minimum of 150 to 300 min/wk of moderate physical activity (MPA), 75 to 150 min/wk of vigorous physical activity (VPA), or an equivalent combination of both. However, it remains unclear whether higher levels of long-term VPA and MPA are, independently and jointly, associated with lower mortality. METHODS: A total of 116 221 adults from 2 large prospective US cohorts (Nurses' Health Study and Health Professionals Follow-up Study, 1988-2018) were analyzed. Detailed self-reported leisure-time physical activity was assessed with a validated questionnaire, repeated up to 15 times during the follow-up. Cox regression was used to estimate the hazard ratio and 95% CI of the association between long-term leisure-time physical activity intensity and all-cause and cause-specific mortality. RESULTS: During 30 years of follow-up, we identified 47 596 deaths. In analyses mutually adjusted for MPA and VPA, hazard ratios comparing individuals meeting the long-term leisure-time VPA guideline (75-149 min/wk) versus no VPA were 0.81 (95% CI, 0.76-0.87) for all-cause mortality, 0.69 (95% CI, 0.60-0.78) for cardiovascular disease (CVD) mortality, and 0.85 (95% CI, 0.79-0.92) for non-CVD mortality. Meeting the long-term leisure-time MPA guideline (150-299 min/wk) was similarly associated with lower mortality: 19% to 25% lower risk of all-cause, CVD, and non-CVD mortality. Compared with those meeting the long-term leisure-time physical activity guidelines, participants who reported 2 to 4 times above the recommended minimum of long-term leisure-time VPA (150-299 min/wk) or MPA (300-599 min/wk) showed 2% to 4% and 3% to 13% lower mortality, respectively. Higher levels of either long-term leisure-time VPA (≥300 min/wk) or MPA (≥600 min/wk) did not clearly show further lower all-cause, CVD, and non-CVD mortality or harm. In joint analyses, for individuals who reported <300 min/wk of long-term leisure-time MPA, additional leisure-time VPA was associated with lower mortality; however, among those who reported ≥300 min/wk of long-term leisure-time MPA, additional leisure-time VPA did not appear to be associated with lower mortality beyond MPA. CONCLUSIONS: The nearly maximum association with lower mortality was achieved by performing ≈150 to 300 min/wk of long-term leisure-time VPA, 300 to 600 min/wk of long-term leisure-time MPA, or an equivalent combination of both.

Adult Moyamoya Disease and Syndrome: Current Perspectives and Future Directions: A Scientific Statement From the American Heart Association/American Stroke Association.

Adult moyamoya disease and syndrome are rare disorders with significant morbidity and mortality. A writing group of experts was selected to conduct a literature search, summarize the current knowledge on the topic, and provide a road map for future investigation. The document presents an update in the definitions of moyamoya disease and syndrome, modern methods for diagnosis, and updated information on pathophysiology, epidemiology, and both medical and surgical treatment. Despite recent advancements, there are still many unresolved questions about moyamoya disease and syndrome, including lack of unified diagnostic criteria, reliable biomarkers, better understanding of the underlying pathophysiology, and stronger evidence for treatment guidelines. To advance progress in this area, it is crucial to acknowledge the limitations and weaknesses of current studies and explore new approaches, which are outlined in this scientific statement for future research strategies.

Guideline Adherence and Practice Patterns in the Management of Medullary Thyroid Cancer.

INTRODUCTION: Little is known about nationwide practice patterns for the management medullary thyroid cancer (MTC) in relation to the 2015 American Thyroid Association guidelines and their impact on survival. METHODS: Using the Surveillance, Epidemiology, and End Results Program database (2000-2018), MTC treatment patterns were evaluated in terms of adherence to the 2015 American Thyroid Association guidelines across three time periods (2000-2009, 2010-2015, and 2016-2018). Outcomes of interest were guideline concordance, treatment utilization trends, disease-specific survival (DSS), and overall survival (OS). RESULTS: A total of 3332 patients with MTC were identified. Of which, 53.8%, 33.2%, and 11.4% of patients had localized, regional, and distant disease, respectively. In patients with locoregional disease, the rate of guideline-concordant surgery improved over time from 63.0% in 2000-2009 to 76.0% in 2016-2018 (P < 0.001). Guideline-concordant care was associated with increased OS (HR = 1.85, 95% CI: 1.42-2.43, P < 0.001) in patients with localized disease and increased DSS (HR = 1.65, 95% CI: 1.01-2.54, P < 0.001) and OS (HR = 1.89, 95% CI: 1.35-2.58, P < 0.001) in patients with regional disease. The median OS and DSS in patients with distant disease were 31 and 55 mo, respectively, and the rate of chemotherapy use rose from 21.6% to 39.2% (P = 0.003). CONCLUSIONS: The rate of guideline-concordant surgery for locoregional MTC increased after guideline publication in 2015, with an observed prolongment in OS and DSS. Chemotherapy use among patients with distant disease has increased over time, but their prognosis remains variable.

Evidence supporting the choice of a new cardiovascular risk equation for Australia.

This article reviews the risk equations recommended for use in international cardiovascular disease (CVD) primary prevention guidelines and assesses their suitability for use in Australia against a set of a priori defined selection criteria. The review and assessment were commissioned by the National Heart Foundation of Australia on behalf of the Australian Chronic Disease Prevention Alliance to inform recommendations on CVD risk estimation as part of the 2023 update of the Australian CVD risk assessment and management guidelines. Selected international risk equations were assessed against eight selection criteria: development using contemporary data; inclusion of established cardiovascular risk factors; inclusion of ethnicity and deprivation measures; prediction of a broad selection of fatal and non-fatal CVD outcomes; population representativeness; model performance; external validation in an Australian dataset; and the ability to be recalibrated or modified. Of the ten risk prediction equations reviewed, the New Zealand PREDICT equation met seven of the eight selection criteria, and met additional usability criteria aimed at assessing the ability to apply the risk equation in practice in Australia.

Clinical practice guideline for deprescribing opioid analgesics: summary of recommendations.

INTRODUCTION: Long term opioids are commonly prescribed to manage pain. Dose reduction or discontinuation (deprescribing) can be challenging, even when the potential harms of continuation outweigh the perceived benefits. The Evidence-based clinical practice guideline for deprescribing opioid analgesics was developed using robust guideline development processes and Grading of Recommendations, Assessment, Development and Evaluation (GRADE) methodology, and contains deprescribing recommendations for adults prescribed opioids for pain. MAIN RECOMMENDATIONS: Eleven recommendations provide advice about when, how and for whom opioid deprescribing should be considered, while noting the need to consider each person's goals, values and preferences. The recommendations aim to achieve: implementation of a deprescribing plan at the point of opioid initiation; initiation of opioid deprescribing for persons with chronic non-cancer or chronic cancer-survivor pain if there is a lack of overall and clinically meaningful improvement in function, quality of life or pain, a lack of progress towards meeting agreed therapeutic goals, or the person is experiencing serious or intolerable opioid-related adverse effects; gradual and individualised deprescribing, with regular monitoring and review; consideration of opioid deprescribing for individuals at high risk of opioid-related harms; avoidance of opioid deprescribing for persons nearing the end of life unless clinically indicated; avoidance of opioid deprescribing for persons with a severe opioid use disorder, with the initiation of evidence-based care, such as medication-assisted treatment of opioid use disorder; and use of evidence-based co-interventions to facilitate deprescribing, including interdisciplinary, multidisciplinary or multimodal care. CHANGES IN MANAGEMENT AS A RESULT OF THESE GUIDELINES: To our knowledge, these are the first evidence-based guidelines for opioid deprescribing. The recommendations intend to facilitate safe and effective deprescribing to improve the quality of care for persons taking opioids for pain.

Treatment intervals and survival for women diagnosed with early breast cancer in Queensland: the Breast Cancer Outcomes Study, a population-based cohort study.

OBJECTIVES: To assess associations between breast cancer-specific survival and timeliness of treatment, based on 2020 Australian guidelines for the treatment of early breast cancer. DESIGN: Population-based cohort study; analysis of linked Queensland Cancer Register, patient medical record, and National Death Index data, supplemented by telephone interviews. SETTING, PARTICIPANTS: Women aged 20-79 years diagnosed with invasive breast cancer during 1 March 2010 - 30 June 2013, followed to 31 December 2020. MAIN OUTCOME MEASURES: Breast cancer-specific survival for women who received or did not receive treatment within the recommended timeframe, overall and for six treatment intervals; optimal cut-points for each treatment interval; characteristics of women for whom treatment was not provided within the recommended timeframe. RESULTS: Of 5426 eligible women, 4762 could be invited for interviews; complete data were available for 3044 women (56% of eligible women, 65% of invited women). Incomplete compliance with guideline interval recommendations was identified for 1375 women (45%); their risk of death from breast cancer during the follow-up period was greater than for those for whom guideline compliance was complete (adjusted hazard ratio [aHR], 1.43; 95% confidence interval [CI], 1.04-1.96). Risk of death was greater for women for whom the diagnosis to surgery interval exceeded 29 days (aHR, 1.76; 95% CI, 1.19-2.59), the surgery to chemotherapy interval exceeded 36 days (aHR, 1.63; 95% CI, 1.13-2.36), or the chemotherapy to radiotherapy interval exceeded 31 days (aHR, 1.83; 95% CI, 1.19-2.80). Treatment intervals longer than recommended were more frequent for women for whom breast cancer was detected by public facility screening (adjusted odds ratio [aOR], 1.58; 95% CI, 1.22-2.04) or by symptoms (aOR, 1.39; 95% CI, 1.09-1.79) than when cancer had been detected in private facilities, and for women without private health insurance (aOR, 1.96; 95% CI, 1.66-2.32) or living outside major cities (aOR, 1.38; 95% CI, 1.18-1.62). CONCLUSIONS: Breast cancer-specific survival was poorer for women for whom the diagnosis to surgery, surgery to chemotherapy, or chemotherapy to radiotherapy intervals exceeded guideline-recommended limits. Our findings support 2020 Australian guideline recommendations regarding timely care.

The representation of women on Australian clinical practice guideline panels, 2010-2020.

OBJECTIVES: To assess the composition by gender of Australian clinical practice guideline development panels; to explore guideline development-related factors that influence the composition of panels. DESIGN, SETTING, PARTICIPANTS: Survey of clinical guidelines published in Australia during 2010-2020 that observed the 2016 NHMRC Standards for Guidelines, identified (June 2021) in the NHMRC Clinical Practice Guideline Portal or by searching the Guideline International Network guidelines library, the Trip medical database, and PubMed. The gender of contributors to guideline development was inferred from gendered titles (guideline documents) or pronouns (online biographies). MAIN OUTCOME MEASURES: The overall proportion of guideline panel members - the guideline contributors who formally considered evidence and formulated recommendations (ie, guideline panel chairs and members) - who were women. RESULTS: Of 406 eligible guidelines, 335 listed the names of people who contributed to their development (82%). Of 7472 named contributors (including 511 guideline panel chairs [6.8%] and 5039 guideline panel members [67.4%]), 3514 were men (47.0%), 3345 were women (44.8%), and gender could not be determined for 612 (8.2%). A total of 215 guideline panel chairs were women (42.1%), 280 were men (54.8%); 2566 guideline panel members were men (50.9%), 2071 were women (41.1%). The proportion of female guideline panel members was smaller than 40% for 179 guidelines (53%) and larger than 60% for 71 guidelines (21%). The median guideline proportion of female panel members was smaller than 50% for all but two years (2017, 2018). CONCLUSIONS: The representation of women in health leadership roles in Australia does not reflect their level of participation in the health care workforce. In particular, clinical guideline development bodies should develop transparent policies for increasing the participation of women in guideline development panels.

Recommendations for culturally safe clinical kidney care for First Nations Australians: a guideline summary.

INTRODUCTION: First Nations Australians display remarkable strength and resilience despite the intergenerational impacts of ongoing colonisation. The continuing disadvantage is evident in the higher incidence, prevalence, morbidity and mortality of chronic kidney disease (CKD) among First Nations Australians. Nationwide community consultation (Kidney Health Australia, Yarning Kidneys, and Lowitja Institute, Catching Some Air) identified priority issues for guideline development. These guidelines uniquely prioritised the knowledge of the community, alongside relevant evidence using an adapted GRADE Evidence to Decision framework to develop specific recommendations for the management of CKD among First Nations Australians. MAIN RECOMMENDATIONS: These guidelines explicitly state that health systems have to measure, monitor and evaluate institutional racism and link it to cultural safety training, as well as increase community and family involvement in clinical care and equitable transport and accommodation. The guidelines recommend earlier CKD screening criteria (age ≥ 18 years) and referral to specialists services with earlier criteria of kidney function (eg, estimated glomerular filtration rate [eGFR], ≤ 45 mL/min/1.73 m2 , and a sustained decrease in eGFR, > 10 mL/min/1.73 m2 per year) compared with the general population. CHANGES IN MANAGEMENT AS RESULT OF THE GUIDELINES: Our recommendations prioritise health care service delivery changes to address institutional racism and ensure meaningful cultural safety training. Earlier detection of CKD and referral to nephrologists for First Nations Australians has been recommended to ensure timely implementation to preserve kidney function given the excess burden of disease. Finally, the importance of community with the recognition of involvement in all aspects and stages of treatment together with increased access to care on Country, particularly in rural and remote locations, including dialysis services.

Patterns of care for people with small cell lung cancer in Victoria, 2011-19: a retrospective, population-based registry data study.

OBJECTIVES: To report stage-specific patterns of treatment and the influence of management and treatment type on survival rates for people newly diagnosed with small cell lung cancer (SCLC). DESIGN: Cross-sectional patterns of care study; analysis of data prospectively collected for the Victorian Lung Cancer Registry (VLCR). SETTING, PARTICIPANTS: All people diagnosed with SCLC in Victoria during 1 April 2011 - 18 December 2019. MAIN OUTCOME MEASURES: Stage-specific management and treatment of people with SCLC; median survival time. RESULTS: During 2011-19, 1006 people were diagnosed with SCLC (10.5% of all lung cancer diagnoses in Victoria); their median age was 69 years (interquartile range [IQR], 62-77 years), 429 were women (43%), and 921 were current or former smokers (92%). Clinical stage was defined for 896 people (89%; TNM stages I-III, 268 [30%]; TNM stage IV, 628 [70%]) and ECOG performance status at diagnosis for 663 (66%; 0 or 1, 489 [49%]; 2-4, 174 [17%]). The cases of 552 patients had been discussed at multidisciplinary meetings (55%), 377 people had received supportive care screening (37%), and 388 had been referred for palliative care (39%). Active treatment was received by 891 people (89%): chemotherapy, 843 (84%); radiotherapy, 460 (46%); chemotherapy and radiotherapy, 419 (42%); surgery, 23 (2%). Treatment had commenced within fourteen days of diagnosis for 632 of 875 patients (72%). Overall median survival time from diagnosis was 8.9 months (IQR, 4.2-16 months; stage I-III: 16.3 [IQR, 9.3-30] months; stage IV: 7.2 [IQR, 3.3-12] months). Multidisciplinary meeting presentation (hazard ratio [HR], 0.66; 95% CI, 0.58-0.77), multimodality treatment (HR, 0.42; 95% CI, 0.36-0.49), and chemotherapy within fourteen days of diagnosis (HR, 0.68; 95% CI, 0.48-0.94) were each associated with lower mortality during follow-up. CONCLUSION: Rates of supportive care screening, multidisciplinary meeting evaluation, and palliative care referral for people with SCLC could be improved. A national registry of SCLC-specific management and outcomes data could improve the quality and safety of care.

Systematic review of conceptual and theoretical frameworks used in palliative care and end-of-life care research studies.

BACKGROUND: Frameworks are the conceptual underpinnings of the study. Both conceptual and theoretical frameworks are often used in palliative and end-of-life care studies to help with study design, guide, and conduct investigations. While an increasing number of investigators have included frameworks in their study, to date, there has not been a comprehensive review of frameworks that were utilized in palliative and end-of-life care research studies. AIM: To summarize conceptual and theoretical frameworks used in palliative and end-of-life care research studies. And to synthesize which of eight domains from the National Consensus Project's Clinical Practice Guidelines for Quality Palliative Care (fourth edition) each framework belongs to. DESIGN: Systematic review. DATA SOURCES: Four electronic databases (EMBASE, the Cumulative Index to Nursing and Allied Health, PsychINFO, and PubMed) were searched from July 2010 to September 2021. RESULTS: A total 2231 citations were retrieved, of which 44 articles met eligibility. Across primary studies, 33,801 study participants were captured. Twenty-six investigators (59.1%) proposed previously unpublished frameworks. In 10 studies, investigators modified existing frameworks, mainly to overcome inherent limitations. In eight studies, investigators utilized existing frameworks referenced in previously published studies. There were eight orientations identified among 44 frameworks we reviewed (e.g. system, patient, patient-doctor). CONCLUSIONS: We examined palliative and end-of-life research studies to identify and characterize conceptual or theoretical frameworks proposed or utilized. Of 44 frameworks we reviewed, 21 studies (47.7%) were aligned with a Clinical Practice Guideline's single domain, while the rest two or more of eight guidelines in quality palliative care domains.
