RESUMO

BACKGROUND: Adjuvant breast radiotherapy as a standard component of breast-conserving treatment for early cancer can overtreat many women. Breast MRI is the most sensitive modality to assess local tumour burden. The aim of this study was to determine whether a combination of MRI and pathology findings can identify women with truly localised breast cancer who can safely avoid radiotherapy. METHODS: PROSPECT is a prospective, multicentre, two-arm, non-randomised trial of radiotherapy omission in patients selected using preoperative MRI and postoperative tumour pathology. It is being conducted at four academic hospitals in Australia. Women aged 50 years or older with cT1N0 non-triple-negative breast cancer were eligible. Those with apparently unifocal cancer had breast-conserving surgery (BCS) and, if pT1N0 or N1mi, had radiotherapy omitted (group 1). Standard treatment including excision of MRI-detected additional cancers was offered to the others (group 2). All were recommended systemic therapy. The primary outcome was ipsilateral invasive recurrence rate (IIRR) at 5 years in group 1. Primary analysis occurred after the 100th group 1 patient reached 5 years follow-up. Quality-adjusted life-years (QALYs) and cost-effectiveness of the PROSPECT pathway were analysed. This study is registered with the Australian New Zealand Clinical Trials Registry (ACTRN12610000810011). FINDINGS: Between May 17, 2011, and May 6, 2019, 443 patients with breast cancer underwent MRI. Median age was 63·0 years. MRI detected 61 malignant occult lesions separate from the index cancer in 48 patients (11%). Of 201 group 1 patients who had BCS without radiotherapy, the IIRR at 5 years was 1·0% (upper 95% CI 5·4%). In group 1, one local recurrence occurred at 4·5 years and a second at 7·5 years. In group 2, nine patients had mastectomy (2% of total cohort), and the 5-year IIRR was 1·7% (upper 95% CI 6·1%). The only distant metastasis in the entire cohort was genetically distinct from the index cancer. The PROSPECT pathway increased QALYs by 0·019 (95% CI 0·008-0·029) and saved AU$1980 (95% CI 1396-2528) or £953 (672-1216) per patient. INTERPRETATION: PROSPECT suggests that women with unifocal breast cancer on MRI and favourable pathology can safely omit radiotherapy. FUNDING: Breast Cancer Trials, National Breast Cancer Foundation, Cancer Council Victoria, the Royal Melbourne Hospital Foundation, and the Breast Cancer Research Foundation.

RESUMO

PURPOSE: The World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) is a widely used disability-specific outcome measure. This study develops mapping algorithms to estimate Assessment of Quality of Life (AQoL)-4D utilities based on the WHODAS 2.0 responses to facilitate economic evaluation. METHODS: The study sample comprises people with disability or long-term conditions (n = 3376) from the 2007 Australian National Survey of Mental Health and Wellbeing. Traditional regression techniques (i.e., Ordinary Least Square regression, Robust MM regression, Generalised Linear Model and Betamix Regression) and machine learning techniques (i.e., Lasso regression, Boosted regression, Supported vector regression) were used. Five-fold internal cross-validation was performed. Model performance was assessed using a series of goodness-of-fit measures. RESULTS: The robust MM estimator produced the preferred mapping algorithm for the overall sample with the smallest mean absolute error in cross-validation (MAE = 0.1325). Different methods performed differently for different disability subgroups, with the subgroup with profound or severe restrictions having the highest MAE across all methods and models. CONCLUSION: The developed mapping algorithm enables cost-utility analyses of interventions for people with disability where the WHODAS 2.0 has been collected. Mapping algorithms developed from different methods should be considered in sensitivity analyses in economic evaluations.

RESUMO

OBJECTIVE: The aim of this study was to test the effectiveness of a tailored quitline tobacco treatment ('Quitlink') among people receiving support for mental health conditions. METHODS: We employed a prospective, cluster-randomised, open, blinded endpoint design to compare a control condition to our 'Quitlink' intervention. Both conditions received a brief intervention delivered by a peer researcher. Control participants received no further intervention. Quitlink participants were referred to a tailored 8-week quitline intervention delivered by dedicated Quitline counsellors plus combination nicotine replacement therapy. The primary outcome was self-reported 6 months continuous abstinence from end of treatment (8 months from baseline). Secondary outcomes included additional smoking outcomes, mental health symptoms, substance use and quality of life. A within-trial economic evaluation was conducted. RESULTS: In total, 110 participants were recruited over 26 months and 91 had confirmed outcomes at 8 months post baseline. There was a difference in self-reported prolonged abstinence at 8-month follow-up between Quitlink (16%, n = 6) and control (2%, n = 1) conditions, which was not statistically significant (OR = 8.33 [0.52, 132.09] p = 0.131 available case). There was a significant difference in favour of the Quitlink condition on 7-day point prevalence at 2 months (OR = 8.06 [1.27, 51.00] p = 0.027 available case). Quitlink costs AU$9231 per additional quit achieved. CONCLUSION: The Quitlink intervention did not result in significantly higher rates of prolonged abstinence at 8 months post baseline. However, engagement rates and satisfaction with the 'Quitlink' intervention were high. While underpowered, the Quitlink intervention shows promise. A powered trial to determine its effectiveness for improving long-term cessation is warranted.

RESUMO

OBJECTIVES: Patients with hematological malignancies are likely to develop hypogammaglobulinemia. Immunoglobulin (Ig) is commonly given to prevent infections, but its overall costs and cost-effectiveness are unknown. METHODS: A systematic review was conducted following the PRISMA guidelines to assess the evidence on the costs and cost-effectiveness of Ig, administered intravenously (IVIg) or subcutaneously (SCIg), in adults with hematological malignancies. RESULTS: Six studies met the inclusion criteria, and only two economic evaluations were identified; one cost-utility analysis (CUA) of IVIg versus no Ig, and another comparing IVIg with SCIg. The quality of the evidence was low. Compared to no treatment, Ig reduced hospitalization rates. One study reported no significant change in hospitalizations following a program to reduce IVIg use, and an observational study comparing IVIg with SCIg suggested that there were more hospitalizations with SCIg but lower overall costs per patient. The CUA comparing IVIg versus no Ig suggested that IVIg treatment was not cost-effective, and the other CUA comparing IVIg to SCIg found that home-based SCIg was more cost-effective than IVIg, but both studies had serious limitations. CONCLUSIONS: Our review highlighted key gaps in the literature: the cost-effectiveness of Ig in patients with hematological malignancies is very uncertain. Despite increasing Ig use worldwide, there are limited data regarding the total direct and indirect costs of treatment, and the optimal use of Ig and downstream implications for healthcare resource use and costs remain unclear. Given the paucity of evidence on the costs and cost-effectiveness of Ig treatment in this population, further health economic research is warranted.

RESUMO

BACKGROUND: While policies to reduce smoking in many countries have been successful, disadvantaged groups (such as low-income groups) have only seen minor gains. People with disability are one such disadvantaged group and are more likely to smoke. However, evidence is limited on trends and inequalities in smoking for disabled people and on whether those also on low incomes are more likely to smoke. METHODS: We use annual data from 2001 to 2020 of the Household Income and Labour Dynamics in Australia survey. We use a Bayesian model to estimate smoking prevalence trends and inequalities for people with disability (2020, n = 1,370) and without disability (2020, n = 6,229) across the whole population and within income tertiles. To avoid reverse causation (smoking causing disability), we focus on younger people (15-44 years). RESULTS: Absolute reductions (per 100 people, [95% credible intervals]) in smoking were similar for people with (-13 [-16, -11]) and without disability (-15 [-16, -14]), with stable absolute but increasing relative inequalities. In the low-income group, absolute reductions in smoking prevalence for people with disability (-10 [-14, -6]) were smaller than in people without disability (-14 [-15, -12]), resulting in moderate evidence for increasing absolute inequalities (4 [0, 8]) and strong evidence for increasing relative inequalities. In high-income groups, disability-related absolute inequalities narrowed (-6 [-10, -3]), and relative inequalities were stable. CONCLUSIONS: Disabled people in Australia, especially those on low incomes, show signs of being left behind in efforts to reduce smoking.

RESUMO

INTRODUCTION: This study estimates the extent to which individuals' smoking cessation and relapse patterns are associated with the smoking behavior of their household members. AIMS AND METHODS: Longitudinal data on household members' smoking behavior was sourced from a representative sample of 12 723 Australians who ever reported smoking between 2001 and 2019. Controlling for a rich set of confounders, multivariate regression analyses were used to predict the likelihood of smoking cessation and relapse given other household members' smoking status and their relationship type. The models were then used to forecast smoking prevalence over 10 years across different household types. RESULTS: Individuals living with a smoking spouse were less likely to quit (OR 0.77 [95% CI 0.72;0.83]) and more likely to relapse (OR 1.47 [95% CI 1.28;1.69]) compared to those living with nonsmoking spouses. Subsequently, the proportion of smokers living with other smoking household members increased by 15% between 2011 and 2019. A 10-year forecast using the smoking cessation and relapse models predicts that, on average, smokers living with nonsmokers will reduce by 43%, while those living alone or with a smoking partner will only reduce by 26% and 28% respectively. CONCLUSIONS: Over time, those who are still smoking are more likely to live with other smokers. Therefore, the current cohort of smokers is increasingly less likely to quit and more likely to relapse. Smoking projection models that fail to account for this dynamic risk may overstate the downstream health benefits and health cost savings. Interventions that encourage smoking cessation at the household level, particularly for spouses, may assist individuals to quit and abstain from smoking. IMPLICATIONS: The current and future paradigm shift in the smoking environment suggests that smoking cessation and relapse prevention policies should consider household structure. Policies designed to affect smoking at the household level are likely to be particularly effective. When estimating the long-term benefits of current smoking policies intrahousehold smoking behavior needs to be considered.

RESUMO

BACKGROUND: Medicines are the most frequent health care intervention type; their safe use provides significant benefits, but inappropriate use can cause harm. Systemic primary care approaches can manage serious medication-related problems in a timely manner. OBJECTIVES: ACTMed (ACTivating primary care for MEDicine safety) uses information technology and financial incentives to encourage pharmacists to work more closely with general practitioners to reduce the risk of harm, improve patients' experience of care, streamline workflows, and increase the efficiency of medical care. METHODS AND ANALYSIS: The stepped wedge cluster randomised trial in 42 Queensland primary care practices will assess the effectiveness of the ACTMed intervention. The primary outcome will be the proportion of people at risk of serious medication-related problems - patients with atrial fibrillation, heart failure, cardiovascular disease, type 2 diabetes, or asthma or chronic obstructive pulmonary disease - who experience such problems. We will also estimate the cost per averted serious medication-related problem and the cost per averted potentially preventable medication-related hospitalisation. ETHICS APPROVAL: The University of Queensland Human Research Ethics Committee approved the pilot (2021/HE002189) and trial phases of the ACTMed study (2022/HE002136). Access to Patron data was granted by the Patron Data Governance Committee (PAT052ACTMed). Access to linked hospitalisations and deaths data are subject to Public Health Act approval (pending). DISSEMINATION OF FINDINGS: A comprehensive dissemination plan will be co-developed by the researchers, the ACTMed steering committee and consumer advisory group, project partners, and trial site representatives. Aboriginal and Torres Strait Islander communities will be supported in leading community-level dissemination. TRIAL REGISTRATION: Australian New Zealand Clinical Trials Registry (pilot: ACTRN12622000595718; 21 April 2022; full trial: ACTRN12622000574741; 14 April 2022).

RESUMO

Several Organisation for Economic Co-operation and Development countries have constrained Disability Income Insurance (DI) eligibility and reassessed those on DI to encourage workforce participation. But these policies can also have unintended consequences. While receiving less income can directly worsen physical and mental health, the stress related to reassessment and the possibility of losing DI may also adversely affect mental health. This paper uses Australian population-wide administrative data to explore how a 2014 policy - where DI recipients under 35 were reassessed under stricter criteria - affected healthcare use. We exploit this age targeting using a difference-in-difference regression design and find that the policy increased nervous system drug prescriptions (which includes antidepressants). Our findings suggest that the reassessment of DI recipients, even without income loss, may have had a significant negative impact on their mental health. DI reassessment policies may have the unintended consequence of worsening mental health and this needs be considered when deciding if reassessment is worthwhile.

RESUMO

Globally, Indigenous populations experience poorer health but use less primary healthcare than their non-Indigenous counterparts. In 2010, the Australian government introduced a targeted reform aimed at reducing these disparities. The reform reduced, or abolished prescription medicine co-payments and provided financial incentives for GPs to better manage chronic disease care for Indigenous peoples. Exploiting the framework of a natural experiment, we investigate how the reform affected these health disparities in primary and specialist healthcare utilization using longitudinal administrative data from 75,826 Australians, including 1896 Indigenous peoples, with cardiovascular disease. The differences-in-differences estimates indicate that the reform increased primary healthcare use among Indigenous peoples, including 12.9% more prescription medicines, 6.6% more GP services, and 34.0% more chronic disease services, but also reduced specialist attendances by 11.8%. Increases in primary care were larger for those who received the largest co-payment relief and lived in metropolitan regions, whereas the reduction in specialist attendances was concentrated among lower income Indigenous patients. Affirmative action can reduce inequalities in Indigenous use of primary healthcare, albeit careful design is required to ensure that benefits are equitable and do not lead to substitution away from valuable, or necessary, care.

RESUMO

OBJECTIVES: To the best of our knowledge, no published clinical guidelines have ever undergone an economic evaluation to determine whether their implementation represented an efficient allocation of resources. Here, we perform an economic evaluation of national clinical guidelines designed to reduce unnecessary blood transfusions before, during, and after surgery published in 2012 by Australia's sole public blood provider, the National Blood Authority (NBA). METHODS: We performed a cost analysis from the government perspective, comparing the NBA's cost of implementing their perioperative patient blood management guidelines with the estimated resource savings in the years after publication. The impact on blood products, patient outcomes, and medication use were estimated for cardiac surgeries only using a large national registry. We adopted conservative counterfactual positions over a base-case 3-year time horizon with outcomes predicted from an interrupted time-series model controlling for differences in patient characteristics and hospitals. RESULTS: The estimated indexed cost of implementing the guidelines of A$1.5 million (2018-2019 financial year prices) was outweighed by the predicted blood products resource saving alone of A$5.1 million (95% confidence interval A$1.4 million-A$8.8 million) including savings of A$2.4 million, A$1.6 million, and A$1.2 million from reduced red blood cell, platelet, and fresh frozen plasma use, respectively. Estimated differences in patient outcomes were highly uncertain and estimated differences in medication were financially insignificant. CONCLUSIONS: Insofar as they led to a reduction in red blood cell, platelet, and fresh frozen plasma use during cardiac surgery, implementing the perioperative patient blood management guidelines represented an efficient use of the NBA's resources.

RESUMO

BACKGROUND: Engagement in work is an important determinant of health. In response to the COVID-19 pandemic, public health measures imposed to reduce viral transmission resulted in large-scale loss of work during the early stages of the pandemic, contributing to declined mental and physical health. As the pandemic unfolded, the Australian economy began to recover and some people could return to work, whilst localised lockdowns resulted in further loss of work for others. The long-term health effects of work loss remain unexplored within the COVID-19 pandemic context, in addition to whether any health effects are persistent upon returning to work. METHODS: A prospective longitudinal cohort study of 2603 participants across Australia monitored changes in health and work between March and December 2020, with participants completing surveys at baseline and 1, 3 and 6 months later. Outcomes described psychological distress, and mental and physical health. Linear mixed regression models examined associations between changes in health and experiences of work loss, and return to work, over time. RESULTS: Losing work during the early stages of the pandemic was associated with long-term poorer mental health, which began to recover over time as some returned to work. Physical health deteriorated over time, greater for people not working at baseline. Being out of work was associated with poorer mental health, but better physical health. These effects were larger for people that had recently lost work than for people with sustained work loss, and retaining employment played a protective role. Generally, returning to work resulted in poorer physical health and improvements in mental health, although this depended on the broader context of changes in work. CONCLUSIONS: Work cessation during the pandemic led to poor health outcomes and had long-lasting effects. Returning to work benefits mental health but may reduce physical activity in the short-term. We encourage the provision of accessible mental health supports and services immediately following loss of work, and for people with prolonged forms of work loss.

RESUMO

This paper establishes a unified framework to fully account for the changing social gradient over the lifecycle in terms of a sufficient set of mobility indices characterizing the coevolution of socioeconomic status and health within each of a series of overlapping cohorts. We proceed to demonstrate the impact of selective mortality on health inequality changes, making use of a counterfactual health distribution for the start of the study period that leaves out those who are known to die before the end. Specifically, initial differences between the average health and educational attainment rank of survivors and nonsurvivors are found in our empirical study to be an increasingly important factor explaining changes in the education-health gradient in older cohorts in Great Britain. Our identification strategy has the advantage that it does not require the imputation of the "would be" health of nonsurvivors, which if carried out using inverse probability weighting procedures-as in several previous studies-is shown to bias estimates of this direct effect of selective mortality toward zero. Parallel results for the income-health gradient exhibit stronger confounding influences due to a number of other factors given that income is a less stable indicator of socioeconomic status in adulthood.

RESUMO

Purpose To determine if losing work during the COVID-19 pandemic is associated with mental and physical health status. To determine if social interactions and financial resources moderate the relationship between work loss and health. Methods Participants were Australians aged 18 + years that were employed in paid work prior to the COVID-19 pandemic who responded to an online or telephone survey from 27th March to 12th June 2020 as part of a prospective longitudinal cohort study. Outcome measures include Kessler-6 score > 18 indicating high psychological distress, and Short Form 12 (SF-12) mental health or physical health component score < = 45 indicating poor mental or physical health. Results The cohort consisted of 2,603 respondents, including groups who had lost their job (N = 541), were not working but remained employed (N = 613), were working less (N = 660), and whose work was unaffected (N = 789). Three groups experiencing work loss had greater odds of high psychological distress (AOR = 2.22-3.66), poor mental (AOR = 1.78-2.27) and physical health (AOR = 2.10-2.12) than the unaffected work group. Poor mental health was more common than poor physical health. The odds of high psychological distress (AOR = 5.43-8.36), poor mental (AOR = 1.92-4.53) and physical health (AOR = 1.93-3.90) were increased in those reporting fewer social interactions or less financial resources. Conclusion Losing work during the COVID-19 pandemic is associated with mental and physical health problems, and this relationship is moderated by social interactions and financial resources. Responses that increase financial security and enhance social connections may alleviate the health impacts of work loss.

RESUMO

Importance: Cytisine is more effective than placebo and nicotine replacement therapy for smoking cessation. However, cytisine has not been tested against the most effective smoking cessation medication, varenicline, which is associated with adverse events known to lead to discontinuation of therapy. Objective: To examine whether standard cytisine treatment (25 days) was at least as effective as standard varenicline treatment (84 days) for smoking cessation. Design, Setting, and Participants: This noninferiority, open-label randomized clinical trial with allocation concealment and blinded outcome assessment was undertaken in Australia from November 2017 through May 2019; follow-up was completed in January 2020. A total of 1452 Australian adult daily smokers willing to make a quit attempt were included. Data collection was conducted primarily by computer-assisted telephone interview, but there was an in-person visit to validate the primary outcome. Interventions: Treatments were provided in accordance with the manufacturers' recommended dosage: cytisine (n = 725), 1.5-mg capsules taken 6 times daily initially then gradually reduced over the 25-day course; varenicline (n = 727), 0.5-mg tablets titrated to 1 mg twice daily for 84 days (12 weeks). All participants were offered referral to standard telephone behavioral support. Main Outcomes and Measures: The primary outcome was 6-month continuous abstinence verified using a carbon monoxide breath test at 7-month follow-up. The noninferiority margin was set at 5% and the 1-sided significance threshold was set at .025. Results: Among 1452 participants who were randomized (mean [SD] age, 42.9 [12.7] years; 742 [51.1%] women), 1108 (76.3%) completed the trial. Verified 6-month continuous abstinence rates were 11.7% for the cytisine group and 13.3% for the varenicline group (risk difference, -1.62% [1-sided 97.5% CI, -5.02% to ∞]; P = .03 for noninferiority). Self-reported adverse events occurred less frequently in the cytisine group (997 events among 482 participants) compared with the varenicline group (1206 events among 510 participants) and the incident rate ratio was 0.88 (95% CI, 0.81 to 0.95; P = .002). Conclusions and Relevance: Among daily smokers willing to quit, cytisine treatment for 25 days, compared with varenicline treatment for 84 days, failed to demonstrate noninferiority regarding smoking cessation.

RESUMO

BACKGROUND: To achieve the World Health Organization hepatitis C virus (HCV) elimination targets, it is essential to increase access to direct-acting antivirals (DAAs), especially among people who inject drugs (PWID). We aimed to determine the effectiveness of providing DAAs in primary care, compared with hospital-based specialist care. METHODS: We randomized PWID with HCV attending primary care sites in Australia or New Zealand to receive DAAs at their primary care site or local hospital (standard of care [SOC]). The primary outcome was to determine whether people treated in primary care had a noninferior rate of sustained virologic response at Week 12 (SVR12), compared to historical controls (consistent with DAA trials at the time of the study design); secondary outcomes included comparisons of treatment initiation, SVR12 rates, and the care cascade by study arm. RESULTS: We recruited 140 participants and randomized 136: 70 to the primary care arm and 66 to the SOC arm. The SVR12 rate (100%, 95% confidence interval [CI] 87.7-100) of people treated in primary care was noninferior when compared to historical controls (85% assumed). An intention-to-treat analysis revealed that the proportion of participants commencing treatment in the primary care arm (75%, 43/57) was significantly higher than in the SOC arm (34%, 18/53; P < .001; relative risk [RR] 2.48, 95% CI 1.54-3.95), and the proportion of participants with SVR12 was significantly higher in the primary care arm, compared to in the SOC arm (49% [28/57] and 30% [16/53], respectively; P = .043; RR 1.63, 95% CI 1.0-2.65). CONCLUSIONS: Providing HCV treatment in primary care increases treatment uptake and cure rates. Approaches that increase treatment uptake among PWID will accelerate elimination strategies.

RESUMO

BACKGROUND: International comparisons of social inequalities in health outcomes and behaviors are challenging. Due to the level of disaggregation often required, data can be sparse and methods to make adequately powered comparisons are lacking. We aimed to illustrate the value of a hierarchical Bayesian approach that partially pools country-level estimates, reducing the influence of sampling variation and increasing the stability of estimates. We also illustrate a new way of simultaneously displaying the uncertainty of both relative and absolute inequality estimates. METHODS: We used the 2014 European Social Survey to estimate smoking prevalence, absolute, and relative inequalities for men and women with and without disabilities in 21 European countries. We simultaneously display smoking prevalence for people without disabilities (x-axis), absolute (y-axis), and relative inequalities (contour lines), capturing the uncertainty of these estimates by plotting a 2-D normal approximation of the posterior distribution from the full probability (Bayesian) analysis. RESULTS: Our study confirms that across Europe smoking prevalence is generally higher for people with disabilities than for those without. Our model shifts more extreme prevalence estimates that are based on fewer observations, toward the European mean. CONCLUSIONS: We demonstrate the utility of partial pooling to make adequately powered estimates of inequality, allowing estimates from countries with smaller sample sizes to benefit from the increased precision of the European average. Including uncertainty on our inequality plot provides a useful tool for evaluating both the geographical patterns of variation in, and strength of evidence for, differences in social inequalities in health.

RESUMO

BACKGROUND AND OBJECTIVES: Blood services are tasked with efficiently maintaining a reliable blood supply, and there has been much debate over the use of incentives to motivate prosocial activities. Thus, it is important to understand the relative effectiveness of interventions for increasing donations. MATERIALS AND METHODS: This systematic review used a broad search strategy to identify randomized controlled trials comparing interventions for increasing blood donations. After full-text review, 28 trials from 25 published articles were included. Sufficient data for meta-analysis were available from 27 trials. Monetary incentives were assumed to be equivalent regardless of value, and non-monetary incentives were assumed to be equivalent regardless of type. Non-incentive-based interventions identified included existing practice, letters, telephone calls, questionnaires, and the combination of a letter & telephone call. A network meta-analysis was used to pool the results from identified trials. A subgroup analysis was performed in populations of donors and non-donors as sensitivity analyses. RESULTS: The best performing interventions were letter & telephone call and telephone call-only with odds ratios of 3·08 (95% CI: 1·99, 4·75) and 1·99 (95% CI: 1·47, 2·69) compared to existing practice, respectively. With considerable uncertainty around the pooled effect, we found no evidence that monetary incentives were effective at increasing donations compared to existing practice. Non-monetary incentives were only effective in the donor subgroup. CONCLUSION: When pooling across modes of interventions, letter & telephone call and telephone call-only are effective at increasing blood donations. The effectiveness of incentives remains unclear with limited, disparate evidence identified.

RESUMO

PURPOSE: Stigma and discrimination are central concerns for people with mental health problems. The aim of the study was to carry out a follow-up survey of a national survey of experiences of avoidance, discrimination and positive treatment in people with mental health problems to explore how those experiences relate to health service use. METHODS: In 2017, telephone interviews were carried out with 655 Australians aged 18+, who had participated in a 2014 survey and reported a mental health problem or scored highly on a symptom screening questionnaire. Questions covered mental health, disclosure, health service utilisation, and experiences of avoidance, discrimination and positive treatment in a variety of different settings. Regression analyses were used to assess the extent to which count of settings of experiences of avoidance, discrimination or positive treatment at baseline (2014) or follow-up (2017) predicted health service use at follow-up. RESULTS: An increase in past experiences of discrimination was associated with a greater number of visits to hospital or specialist doctors and an increase in positive treatment was associated with a greater number of visits to a mental health professional. Increases in both positive and negative experiences were associated with greater healthcare costs, but the costs were greatest for discrimination at follow-up (concurrent discrimination), primarily due to the cost of nights in hospital. CONCLUSIONS: While both discrimination and positive treatment are associated with greater healthcare costs, concurrent experiences were shown to be more important correlates of health service use than past experiences. Moreover, those in supportive environments may be more willing to engage in earlier evidence-based treatment for mental health problems.

RESUMO

OBJECTIVES: Trials comparing the effects of transfusing RBC units of different storage durations have considered mortality or morbidity as outcomes. We perform the first economic evaluation alongside a full age of blood clinical trial with a large population assessing the impact of RBC storage duration on quality-of-life and costs in critically ill adults. DESIGN: Quality-of-life was measured at 6 months post randomization using the EuroQol 5-dimension 3-level instrument. The economic evaluation considers quality-adjusted life year and cost implications from randomization to 6 months. A generalized linear model was used to estimate incremental costs (2016 U.S. dollars) and quality-adjusted life years, respectively while adjusting for baseline characteristics. SETTING: Fifty-nine ICUs in five countries. PATIENTS: Adults with an anticipated ICU stay of at least 24 hours when the decision had been made to transfuse at least one RBC unit. INTERVENTIONS: Patients were randomized to receive either the freshest or oldest available compatible RBC units (standard practice) in the hospital transfusion service. MEASUREMENTS AND MAIN RESULTS: EuroQol 5-dimension 3-level utility scores were similar at 6 months-0.65 in the short-term and 0.63 in the long-term storage group (difference, 0.02; 95% CI, -0.00 to 0.04; p = 0.10). There were no significant differences in resource use between the two groups apart from 3.0 fewer hospital readmission days (95% CI, -5.3 to -0.8; p = 0.01) during follow-up in the short-term storage group. There were no significant differences in adjusted total costs or quality-adjusted life years between the short- and long-term storage groups (incremental costs, -$2,358; 95% CI, -$5,586 to $711) and incremental quality-adjusted life years: 0.003 quality-adjusted life years (95% CI, -0.003 to 0.008). CONCLUSIONS: Without considering the additional supply cost of implementing a freshest available RBC strategy for critical care patients, there is no evidence to suggest that the policy improves quality-of-life or reduces other costs compared with standard transfusion practice.

RESUMO

BACKGROUND: Income-related inequality measures such as the concentration index are often used to describe the unequal distribution of health, health care access, or expenditure in a single measure. This study demonstrates the use of such measures to evaluate the distributional impact of changes in health insurance coverage. We use the example of Medicare Part D in the United States, which increased access to prescription medications for Medicare beneficiaries from 2006. METHODS: Using pooled cross-sectional samples from the Medical Expenditure Panel Survey for 1997-2011, we estimated income-related inequality in drug expenditures over time using the concentration and generalised concentration indices. A difference-in-differences analysis investigated the change in inequality in drug expenditures, as measured using the concentration index and generalised concentration index, between the elderly (over 65 years) and near-elderly (54-63 years) pre- and post-implementation of Medicare Part D. RESULTS: Medicare Part D increased public drug expenditure while out-of-pocket and private spending fell. Public drug expenditures favoured the poor during all study periods, but the degree of pro-poorness declined in the years immediately following the implementation of Part D, with the poor gaining less than the rich in both relative and absolute terms. Part D also appeared to result in a fall in the pro-richness of private insurance drug expenditure in absolute terms but have minimal distributional impact on out-of-pocket expenditure. These effects appeared to be short lived, with a return to the prevailing trends in both concentration and generalised concentration indices several years following the start of Part D. CONCLUSIONS: The implementation of Medicare Part D significantly reduced the degree of pro-poorness in public drug expenditure. The poor gained less of the increased public drug expenditure than the rich in both relative and absolute terms. This study demonstrates how income-related inequality measures can be used to estimate the impact of health system changes on inequalities in health expenditure and provides a guide for future evaluations.
