Background: Research suggests that a high proportion of melanoma in situ (MIS) may be overdiagnosed, potentially contributing to overtreatment, patient harm and inflated costs for individuals and healthcare systems. However, Australia-wide estimates of the magnitude of melanoma overdiagnosis are potentially outdated and there has been no estimation of the cost to the healthcare system.
Objectives: To estimate the magnitude and cost of overdiagnosed MIS and thin invasive melanomas in Australia.
Objective: To synthesise the available evidence on the effects of interventions designed to improve the delivery of healthcare that reduces the greenhouse gas (GHG) emissions of healthcare.
Design: Systematic review and structured synthesis.

Importance: Overuse of surgical procedures is increasing around the world and harms both individuals and health care systems by using resources that could otherwise be allocated to addressing the underuse of effective health care interventions. In low- and middle-income countries (LMICs), there is some limited country-specific evidence showing that overuse of surgical procedures is increasing, at least for certain procedures.
Objectives: To assess factors associated with, extent and consequences of, and potential solutions for low-value surgical procedures in LMICs.
Background: In a therapeutic partnership, physicians rely on patients to describe their health conditions, join in shared decision-making, and engage with supported self-management activities. In shared care, the patient, primary care, and specialist services partner together using agreed processes and outputs for the patient to be placed at the centre of their care. However, few empirical studies have explored physicians' trust in patients and its implications for shared care models.

Objective: To identify and summarize the evidence about the extent of overuse of medications in low- and middle-income countries, its drivers, consequences and potential solutions.
Methods: We conducted a scoping review by searching the databases PubMed®, Embase®, APA PsycINFO® and Global Index Medicus using a combination of MeSH terms and free text words around overuse of medications and overtreatment. We included studies in any language published before 25 October 2021 that reported on the extent of overuse, its drivers, consequences and solutions.
Objective: Overdiagnosis and overuse of healthcare services harm individuals, take resources that could be used to address underuse, and threaten the sustainability of health systems. These problems are attracting increasing attention in low-income and middle-income countries (LMICs). Unaware of any review of relevant evidence, we conducted a scoping review of the evidence around overdiagnosis and overuse of diagnostic and screening tests in LMICs.

We undertook a comprehensive review of all publicly available decision aids for prostate cancer screening, published in (or translated to) the English language, without date restrictions. We included all decision aids from a recent systematic review and screened excluded studies to identify further relevant decision aids.

Methods: We calculated and described standardised time trends in PSA tests, prostate biopsies, treatment of benign prostatic hypertrophy (BPH) and prostate cancer incidence and mortality in Australia in men aged 45-74, 75-84, and 85 + years.
Objectives: To estimate the proportion of cancer diagnoses in Australia that might reasonably be attributed to overdiagnosis by comparing current and past lifetime risks of cancer.
Design, Setting, And Participants: Routinely collected Australian Institute of Health and Welfare national data were analysed to estimate recent (2012) and historical (1982) lifetime risks (adjusted for competing risk of death and changes in risk factors) of diagnoses with five cancers: prostate, breast, renal, thyroid cancers, and melanoma.
Main Outcome Measure: Difference in lifetime risks of cancer diagnosis between 1982 and 2012, interpreted as probable overdiagnosis.
Objectives: To calculate lifetime risks of cancer diagnosis and cancer-specific death, adjusted for competing mortality, and to compare these estimates with the corresponding risks published by the Australian Institute of Health and Welfare (AIHW).
Design, Setting: Analysis of publicly available annual AIHW data on age-specific cancer incidence and mortality - for breast cancer, colorectal cancer, prostate cancer, melanoma of the skin, and lung cancer - and all-cause mortality in Australia, 1982-2013.
Outcome Measures: Lifetime risks of cancer diagnosis and mortality (to age 85), adjusted for competing mortality.
Objectives: To quantify the risk of overdiagnosis associated with prostate cancer screening in Australia using a novel lifetime risk approach.
Design: Modelling and validation of the lifetime risk method using publicly available population data.
Setting: Opportunistic screening for prostate cancer in the Australian population.
Issue Addressed: Childhood obesity is rising in prevalence in Australia. This study aimed to evaluate the impact of the "Have Fun-Be Healthy" (HFBH) intervention, delivered in the Playgroup setting, to generate short term changes in dietary, physical activity and sedentary behaviours of children under 5 years and self-efficacy of parents and primary carers.
Methods: This intervention consisted of eight structured cooking and physical play sessions delivered over a period of 8 weeks by trained facilitators.

Objectives: We performed a systematic review to identify, critically appraise and synthesise the existing literature on the association between SEP and multimorbidity occurrence.
Methods: We searched Medline and Embase from inception to December 2014. Where possible we performed meta-analysis to obtain summary odds ratios (ORs), exploring heterogeneity between studies through sub-group analysis.
Objectives: The evidence for an association between depression and anxiety and increased hypertension risk is inconsistent. We aimed to investigate the association between each of depression and anxiety and incident hypertension.
Methods: We included women born between 1946 and 1951 from the Australian Longitudinal Study on Women's Health, surveyed triennially from 1998 to 2013, without a history of hypertension at baseline.
