Predictive modelling reveals Australian continental risk hotspots for marine debris interactions with key threatened species.

Anthropogenic debris is a global threat that impacts threatened species through various lethal and sub-lethal consequences, as well as overall ecosystem health. This study used a database of over 24,000 beach surveys of marine debris collated by the Australian Marine Debris Initiative from 2012 to 2021, with two key objectives: (1) identify variables that most influence the occurrence of debris hotspots on a continental scale and (2) use these findings to identify likely hotspots of interaction between threatened species and marine debris. The number of particles found in each beach survey was modelled alongside fifteen biological, social, and physical spatial variables including land use, physical oceanography, population, rainfall, distance to waste facilities, ports, and mangroves to identify the significant drivers of debris deposition. The model of best fit for predicting debris particle abundance was calculated using a generalized additive model. Overall, debris was more abundant at sites near catchments with high annual rainfall (mm), intensive land use (km2), and that were nearer to ports (km) and mangroves (km). These results support previous studies which state that mangroves are a significant sink for marine debris, and that large ports and urbanized catchments are significant sources for marine debris. We illustrate the applicability of these models by quantifying significant overlap between debris hotspots and the distributions for four internationally listed threatened species that exhibit debris interactions; green turtle (26,868 km2), dugong (16,164 km2), Australian sea lion (2903 km2) and Flesh-footed Shearwater (2413 km2). This equates to less than 1% (Flesh-footed Shearwater, Australian sea lion), over 2% (green sea turtle) and over 5% (dugong) of their habitat being identified as areas of high risk for marine debris interactions. The results of this study hold practical value, informing decision-making processes, managing debris pollution at continental scales, as well as identifying gaps in species monitoring.

Patterns of publicly funded naltrexone use among patients diagnosed with alcohol use disorder in Ontario.

AIMS: Naltrexone is recommended first-line to manage alcohol use disorder (AUD). With previous studies indicating poor retention on naltrexone, we determined duration of naltrexone use and assessed the association between prescription setting and time to discontinuation in Ontario. METHODS: We conducted a retrospective population-based cohort study among Ontario public drug beneficiaries diagnosed with AUD who initiated publicly funded naltrexone from June 2018 to September 2019. The primary outcome was time to naltrexone discontinuation, with a secondary analysis assessing receipt of at least one prescription refill. We used Cox proportional hazards models and logistic regression to test the association between prescription setting and each medication persistence outcome. RESULTS: Among 2531 new naltrexone patients with AUD, the median duration of naltrexone use was 31 days and 394 (15.6%) continued naltrexone for 6 months or longer. There was no association between setting of initiation and duration of naltrexone use; however, those initiating naltrexone following an acute inpatient hospital stay were more likely to fill a second prescription (aOR 1.43, 95% CI 0.96-2.14), while those initiating after an ED visit were less likely to be dispensed a second prescription (aOR = 0.69, 95% CI 0.52-0.90) compared to those starting in a physician's office. CONCLUSION: Persistence on naltrexone to treat an AUD is low, regardless of the setting of initiation. Further research is needed to elucidate the barriers encountered by patients with AUD that lead to poor treatment persistence in order to develop interventions that facilitate patient-centered access to evidence-based treatment for AUD in the province.

The impact of the OPTN policy change on patients with a durable left ventricular assist device and chronic kidney disease: Analysis of the UNOS database.

BACKGROUND: The Organ Procurement and Transplantation Network (OPTN) implemented modifications in 2018 to the adult heart transplant allocation system to better stratify the most medically urgent transplant candidates. We evaluated the impact of these changes on patients supported by a durable left ventricular assist device (LVAD) with chronic kidney disease (CKD). OBJECTIVE: To evaluate the impact of the OPTN policy change on patients supported by durable left ventricular assist devices (LVAD) with chronic kidney disease (CKD). METHODS: We performed an analysis of patients from the United Network of Organ Sharing Database supported by durable LVAD listed for a heart transplant (HT) between October 17, 2016 and September 30, 2021. Patients were divided into two groups: pre- and postpolicy, depending on whether they were listed on or prior to October 17, 2018. Patients who were on dialysis prior to surgery or discharge were excluded from the analysis. Patients with simultaneous heart and kidney transplants were excluded. Patients who were listed for transplant prepolicy change but transplanted postpolicy change were excluded. This cohort was then subdivided into degrees of CKD based on estimated glomerular filtration rate (eGFR), which resulted in 678 patients (23.7%) in Stage 1 (GFR ≥89.499) (Prepolicy: 345, Postpolicy: 333), 1233 (43.1%) in Stage 2 (89.499 > GFR ≥ 59.499) (Prepolicy: 618, Postpolicy: 615), 613 (21.4%) in Stage 3a (59.499 > GFR ≥ 44.499) (Prepolicy: 291, Postpolicy: 322), 294 (10.3%) in Stage 3b (44.499 > GFR ≥ 29.499) (Prepolicy: 143, Postpolicy: 151), 36 (1.3%) in Stage 4 (29.499 > GFR ≥ 15) (Prepolicy: 21, Postpolicy: 15), and 9 (0.3%) in Stage 5 (15 > GFR) (Prepolicy: 4, Postpolicy: 5). The primary outcome was 1-year and 2-year post-HT survival. RESULTS: There were 2863 patients who met the study criteria (1422 prepolicy, 1441 postpolicy). Overall survival, regardless of CKD stage, was lower following the policy change (p < 0.01). There was a similar risk of primary graft failure (PGF) in the pre- and postpolicy period (1.8% vs. 1.2%, p = 0.26). 1-year overall survival was 93% (91, 94) and 89% (87, 91) in the pre- and postpolicy periods, respectively. 2-year overall survival was 89% (88, 91) and 85% (82, 87) in the pre- and postpolicy periods, respectively. For CKD Stages 1, 2, 3a, 3b, 4, and 5, 1 -year survival was 93% (91, 95), 92% (90,93), 89% (86, 91), 89% (86, 93), 80% (68, 94), and 100% (100, 100), respectively. For CKD Stages 1, 2, 3a, 3b, 4, and 5, 2-year survival was 91% (88, 93), 88% (86, 90), 84% (81, 88), 84% (80, 89), 73% (59, 90), and 100% (100, 100), respectively. Patients with CKD 1 and 2 had better survival compared to those with CKD 3 (p < 0.01) and CKD 4 and 5 (p = 0.03) in the pre- and postpolicy periods. Patients with CKD 3 did not have a survival advantage over those with CKD 4 and 5 (p = 0.25). On cox regression analysis, advancing degrees of CKD were associated with an increased risk of mortality. CONCLUSIONS: Patients with LVAD support had decreased overall survival after the OPTN policy change. Patients with more advanced CKD had lower survival than patients without advanced CKD, though they were not impacted by the OPTN policy change.

Equity, diversity, and inclusion in oncology pharmacy practice: Everyone's business.

INTRODUCTION: Equity, Diversity, and Inclusion (EDI) is gaining increased attention within all industries healthcare being no exception. The terminology Equity, Diversity, and Inclusion and its abbreviation EDI gained popularity in the early 2000's when varied socio-political factors prompted many organisations to examine EDI concepts and how to operationalise them. The growing diversity of our society requires cross-cultural inclusive approaches to increase equity and access to services. METHOD: This unique research is community-led research supported by the British Oncology Pharmacy Association, in which the members of the BOPA community are equal partners to inform action on policies that address EDI. This research was a cross-sectional study involving an online survey of financial BOPA members. RESULTS: Demographic data was extracted, and the quotes were analysed for common themes. The majority of respondents were women, and the largest age group was between 34 and 44. The first cause of microaggressions identified by the respondents was of racial and ethnic origin, followed by marital status and religious nature. Participants described the lack of diversity in senior positions and the microaggressions experienced by those who hold leadership positions. Some participants described how some situations at work made them feel excluded or alienated. The impact of discrimination and bullying/microaggressions extended to patients was also reported. CONCLUSION: Despite strategic directions encompassing this aspect, this research underscores the pressing need for more evidence on the lack of EDI in healthcare institutions. Our findings, located in the pharmacy oncology specialty, have identified the problem and highlighted the potential benefits of addressing it. More needs to be done in training and professional development to address unconscious bias and change behaviours.

"Valorar el trabajo de farmworkers": A thematic analysis of input from farmworkers, advocates, and students in a community documentary project about the future of farm work.

Farm work is one of the nation's most hazardous occupations, and migrant and seasonal farmworkers face significant health inequities. Awareness and understanding of the needs of this population are crucial in assuring they receive appropriate support. Documentary programs can raise awareness of community member views to better inform services and advocacy efforts. Visions for the future of farm work were collected from farmworkers and persons supporting them through a community-based, participatory documentary project led by Student Action with Farmworkers (SAF) from 2021 to 2022. Seventy-nine submissions from participants in North and South Carolina, including text responses and file uploads, were collected and thematically analyzed. Five themes were identified: (1) employment benefits and conditions, (2) living conditions, (3) health access and quality, (4) dignity and visibility of farm work, and (5) policy change for a better future. The visions for the future of farm work expressed by these agricultural workers, advocates, and students raise important implications for agricultural communities, public health practitioners, researchers, funders, and policymakers. Application of these findings in the development and delivery of public health services for farmworkers has the potential to positively impact the morbidity and mortality rates of this at-risk population.

Local government stakeholders' perceptions of potential policy actions to influence both climate change and healthy eating in Victoria: A qualitative study.

ISSUE ADDRESSED: Climate change is a defining public health issue of the 21st century. Food systems are drivers of diet-related disease burden, and account for 30% of global greenhouse gas emissions. Local governments play a crucial role in improving both the healthiness and environmental sustainability of food systems, but the potential for their actions to simultaneously address these two issues is unclear. This study aimed to explore the perceptions of Australian local government stakeholders regarding policy actions simultaneously addressing healthy eating and climate change, and the influences on policy adoption. METHODS: We conducted 11 in-depth semi-structured interviews with stakeholders from four local governments in Victoria, Australia. Data were analysed using reflexive thematic analysis. We applied Multiple Streams Theory (MST) 'problem', 'politics and 'policy' domains to explain policy adoption influences at the local government level. RESULTS: Key influences on local government action aligned with MST elements of 'problem' (e.g., local government's existing risk reports as drivers for climate change action), 'policy' (e.g., budgetary constraints) and 'politics' (e.g., local government executive agenda). We found limited evidence of coherent policy action in the areas of community gardens, food procurement and urban land use. CONCLUSION: Barriers to further action, such as resource constraints and competing priorities, could be overcome by better tailoring policy action areas to community needs, with the help of external partnerships and local government executive support. SO WHAT?: This study demonstrates that Victorian local stakeholders believe they are well-positioned to implement feasible and coherent interventions that address both healthy eating and climate.

Unintended consequences of communicating rapid COVID-19 vaccine policy changes- a qualitative study of health policy communication in Ontario, Canada.

BACKGROUND: The success of the COVID-19 vaccination roll-out depended on clear policy communication and guidance to promote and facilitate vaccine uptake. The rapidly evolving pandemic circumstances led to many vaccine policy amendments. The impact of changing policy on effective vaccine communication and its influence in terms of societal response to vaccine promotion are underexplored; this qualitative research addresses that gap within the extant literature. METHODS: Policy communicators and community leaders from urban and rural Ontario participated in semi-structured interviews (N = 29) to explore their experiences of COVID-19 vaccine policy communication. Thematic analysis was used to produce representative themes. RESULTS: Analysis showed rapidly changing policy was a barrier to smooth communication and COVID-19 vaccine roll-out. Continual amendments had unintended consequences, stimulating confusion, disrupting community outreach efforts and interrupting vaccine implementation. Policy changes were most disruptive to logistical planning and community engagement work, including community outreach, communicating eligibility criteria, and providing translated vaccine information to diverse communities. CONCLUSIONS: Vaccine policy changes that allow for prioritized access can have the unintended consequence of limiting communities' access to information that supports decision making. Rapidly evolving circumstances require a balance between adjusting policy and maintaining simple, consistent public health messages that can readily be translated into action. Information access is a factor in health inequality that needs addressing alongside access to vaccines.

Drivers of change in China's energy-related CO2 emissions.

CO2 emissions are of global concern because of climate change. China has become the largest CO2 emitter in the world and presently accounts for 30% of global emissions. Here, we analyze the major drivers of energy-related CO2 emissions in China from 1978 when the reform and opening-up policy was launched. We find that 1) there has been a 6-fold increase in energy-related CO2 emissions, which was driven primarily (176%) by economic growth followed by population growth (16%), while the effects of energy intensity (-79%) and carbon intensity (-13%) slowed the growth of carbon emissions over most of this period; 2) energy-related CO2 emissions are positively related to per capita gross domestic product (GDP), population growth rate, carbon intensity, and energy intensity; and 3) a portfolio of command-and-control policies affecting the drivers has altered the total emission trend. However, given the major role of China in global climate change mitigation, significant future reductions in China's CO2 emissions will require transformation toward low-carbon energy systems.

A step change model analysis of the establishment of pill testing in one Australian jurisdiction.

This paper applies the theory of change model (Kotter in Harv Bus Rev 2:59-67, 1995; Moore et al. in Viet Nam J Public Health 1(1):66-75, 2013) to describe the pathway that lead to Australia's first pill testing/drug checking services in Canberra, in the Australian Capital Territory. The paper takes each step of the model and illustrates the key activities that largely occurred over an approximately 24 month period resulting in the service being operational on 29 April 2018. The paper demonstrates that leadership, advocacy and activism are key components, alongside evidence, to bringing about public policy change. It provides a unique insight to the extensive efforts undertaken to achieving the first legally sanctioned pill testing at festivals in Australia and provides a positive case study for those seeking to introduce contested harm reduction services in the drug and alcohol field.

Length of initial prescription at hospital discharge and long-term medication adherence for elderly, post-myocardial infarction patients: a population-based interrupted time series study.

BACKGROUND: Preliminary evidence suggests that providing longer duration prescriptions at discharge may improve long-term adherence to secondary preventative cardiac medications among post-myocardial infarction (MI) patients. We implemented and assessed the effects of two hospital-based interventions-(1) standardized prolonged discharge prescription forms (90-day supply with 3 repeats for recommended cardiac medications) plus education and (2) education only-on long-term cardiac medication adherence among elderly patients post-MI. METHODS: We conducted an interrupted time series study of all post-MI patients aged 65-104 years in Ontario, Canada, discharged from hospital between September 2015 and August 2018 with ≥ 1 dispensation(s) for a statin, beta blocker, angiotensin system inhibitor, and/or secondary antiplatelet within 7 days post-discharge. The standardized prolonged discharge prescription forms plus education and education-only interventions were implemented at 2 (1,414 patients) and 4 (926 patients) non-randomly selected hospitals in September 2017 for 12 months, with all other Ontario hospitals (n = 143; 18,556 patients) comprising an external control group. The primary outcome, long-term cardiac medication adherence, was defined at the patient-level as an average proportion of days covered (over 1-year post-discharge) ≥ 80% across cardiac medication classes dispensed at their index fill. Primary outcome data were aggregated within hospital groups (intervention 1, 2, or control) to monthly proportions and independently analyzed using segmented regression to evaluate intervention effects. A process evaluation was conducted to assess intervention fidelity. RESULTS: At 12 months post-implementation, there was no statistically significant effect on long-term cardiac medication adherence for either intervention-standardized prolonged discharge prescription forms plus education (5.4%; 95% CI - 6.4%, 17.2%) or education only (1.0%; 95% CI - 28.6%, 30.6%)-over and above the counterfactual trend; similarly, no change was observed in the control group (- 0.3%; 95% CI - 3.6%, 3.1%). During the intervention period, only 10.8% of patients in the intervention groups received ≥ 90 days, on average, for cardiac medications at their index fill. CONCLUSIONS: Recognizing intervention fidelity was low at the pharmacy level, and no statistically significant post-implementation differences in adherence were found, the trends in this study-coupled with other published retrospective analyses of administrative data-support further evaluation of this simple intervention to improve long-term adherence to cardiac medications.

The effect of increasing Women's autonomy on primary and repeated caesarean sections in Brazil.

Caesarean section (C-section) rates continue to rise globally. Yet, there is little consensus about the key determinants of rising C-section rates and the sources of variation in C-section rates across the world. While C-sections can save lives when medically justified, unnecessary surgical procedures can be harmful for women and babies. We show that a state-wide law passed in São Paulo (Brazil), which increased women's autonomy to choose to deliver via C-section even when not medically necessary, is associated with a 3% increase in overall C-section rates. This association was driven by a 5% increase in primary C-sections, rather than repeated C-sections. Since the law emphasizes women's autonomy, these results are consistent with mothers' demand being an important contributor to high C-section rates in this context.

Ectopic pregnancy in China during 2011-2020: a single-centre retrospective study of 9499 cases.

BACKGROUND: Previous studies have shown that the incidence of ectopic pregnancy (EP) is increasing in China. It is unclear, however, whether the incidence of EP has changed after the implementation of the universal two-child policy in the context of China's aging population and declining fertility rate. METHODS: Data concerning EP from January 2011 to December 2020 were collected from the hospital's electronic medical records, which included the annual number of delivery, caesarean section rate, ectopic pregnancies, treatment of tubal pregnancy, and average costs and length of hospitalization. Trends of the EP incidence were analysed and annual percentage change (APC) was calculated using connected point regression analyses. RESULTS: A total of 9499 cases of EP were collected, among which caesarean scar pregnancy (CSP) accounts for the second highest (6.73%). The EP per 100 deliveries revealed a downward trend, from 7.60% in 2011 to 4.28% in 2020 with an APC of -1.87 (P < 0.05). The maternal age was increased, especially after the implementation of the universal two-child policy. The constituent ratio for the advanced maternal age (≥ 35) and the caesarean section rate, but not the CSP, were also increased. Laparoscopic salpingectomy was the main surgical method, whereas the adoption of laparotomy and laparoscopic salpingostomy was decreasing year by year. CONCLUSIONS: Although no obvious effect of the two-child policy on EP has been observed under the conditions of this study, the change in EP especially in advanced-age women after the policy implementation needs further evaluation. A decreased caesarean section rate, in primipara is beneficial to reducing the CSP.

Perceptions of a food benefit programme that includes financial incentives for the purchase of fruits and vegetables and restrictions on the purchase of foods high in added sugar.

OBJECTIVE: To report perspectives of participants in a food benefit programme that includes foods high in added sugar (FAS) restrictions and FAS restrictions paired with fruits and vegetables (F/V) incentives. DESIGN: Randomised experimental trial in which participant perspectives were an exploratory study outcome. SETTING: Participants were randomised into one of three Supplemental Nutrition Assistance Program (SNAP)-like food benefit programme groups: (1) restriction: not allowed to buy FAS with benefits; (2) restriction paired with incentive: not allowed to buy FAS with benefits and 30 % financial incentive on eligible F/V purchased using benefits; or (3) control: same food purchasing rules as SNAP. Participants were asked questions to assess programme satisfaction. PARTICIPANTS: Adults in the Minneapolis-St. Paul, MN metropolitan area, eligible for but not currently participating in SNAP who completed baseline and follow-up study measures (n 254). RESULTS: Among remaining households in each group, most found the programme helpful in buying nutritious foods (88·2 %-95·7 %) and were satisfied with the programme (89·1 %-93·0 %). Sensitivity analysis results indicate that reported helpfulness and satisfaction with the programme may in some instances be lower among the restriction and the restrictions paired with incentive groups in comparison to the control group. CONCLUSIONS: A food benefit programme that includes restriction on purchase of FAS or restriction paired with a financial incentive for F/V purchases may be acceptable to most SNAP-eligible households with children.

Does an active play standard change childcare physical activity and healthy eating policies? A natural policy experiment.

BACKGROUND: In 2017, the provincial government of British Columbia (BC) implemented a mandatory policy outlining Active Play Standards (AP Standards) to increase physical activity (PA) levels, sedentary and motor skills among children attending licensed childcare centers. Concurrently, a capacity-building initiative was launched to help implement policies and practices supporting both PA and healthy eating (HE) in the early years. This study evaluated differences in center-level PA and HE policies and practices before and after the enforcement of the new provincial AP Standards. METHODS: Using a repeat cross-sectional design, surveys were distributed to managers and staff of licensed childcare facilities serving children aged 2-5 years before (2016-2017 or 'time 1') and after (2018-2019 or 'time 2') implementation of the AP Standards across BC. The total sample included 1,459 respondents (910 and 549 respondents at time 1 and time 2, respectively). Hierarchical mixed effects models were used to examine differences in 9 and 7 PA/sedentary policies and practices, respectively, as well as 11 HE policies between time 1 and time 2. Models controlled for childcare size and area-level population size, education, and income. RESULTS: Compared to centers surveyed at time 1, centers at time 2 were more likely to report written policies related to: fundamental movement skills, total amount of Active Play (AP) time, staff-led AP, unfacilitated play/free play, total amount of outdoor AP time, limiting screen time, breaking up prolonged sitting, staff role modeling of PA, and training staff about PA (P < 0.01 for all 9 policies examined). Compared to time 1, centers at time 2 reported more frequent practices related to ensuring children engaged in at least 120 min of AP, 60 min of outdoor AP daily, and limiting screen time (P < 0.01 for 3 out of 7 practices examined). Despite no additional policy intervention related to HE, centers were more likely to report having written policies related to: HE education for children, encouraging new foods, having family-style meals, offering only milk or water, limiting the amount of juice served, staff role modeling of HE, limiting the types of foods at parties/celebrations and foods brought from home (P < 0.05 for 9 out of 11 HE policies). CONCLUSION: Approximately a year after the implementation of a governmental policy targeting PA supported by a capacity-building initiative, childcare centers reported positive changes in all 9 PA/sedentary policies examined, all 3 out of 7 PA/sedentary practices and 9 out of 11 HE policies evaluated at the center-level.

The impact of an unemployment insurance reform on incidence rates of hospitalisation due to alcohol-related disorders: a quasi-experimental study of heterogeneous effects across ethnic background, educational level, employment status, and sex in Sweden.

BACKGROUND: Many Western countries have scaled back social and health expenditure, including decreases in the generosity and coverage of unemployment insurance, resulting in negative effects on general health and well-being at the aggregate level. Yet, research has not sufficiently looked into heterogeneity of such effects across different subgroups of the population. In Sweden, the 2006 unemployment insurance reform, implemented on the 1st of January 2007, encompassed a drastic increase of insurance fund membership fees, reduced benefit levels, and stricter eligibility requirements. As this particularly affected already socioeconomically disadvantaged groups in society, such as foreign-born and low-educated individuals, the current study hypothesise that the reform would also have a greater impact on health outcomes in these groups. METHODS: Based on register data for the total population, we utilise a quasi-experimental approach to investigate heterogeneous health effects of the reform across ethnic background, educational level, employment status, and sex. Due to behaviourally caused diseases having a relatively shorter lag time from exposure, hospitalisation due to alcohol-related disorders serves as the health outcome. A series of regression discontinuity models are used to analyse monthly incidence rates of hospitalisation due to alcohol-related disorders among individuals aged 30-60 during the study period (2001-2012), with the threshold set to the 1st of January 2007. RESULTS: The results suggest that, in general, there was no adverse effect of the reform on incidence rates of hospitalisation due to alcohol-related disorders. A significant increase is nonetheless detected among the unemployed, largely driven by Swedish-born individuals with Swedish-born or foreign-born parents, low-educated individuals, and men. CONCLUSIONS: We conclude that the Swedish 2006 unemployment insurance reform generally resulted in increasing incidence rates of hospitalisation due to alcohol-related disorders among unemployed population subgroups known to have higher levels of alcohol consumption.

Travelling Far and Wide? Applying the Multiple Streams Framework to Policy-Making in Autocracies.

The Multiple Streams Framework (MSF) builds on the concepts of timing and ambiguity and their effects on the policy process. Since its introduction to agenda-setting in the U.S. presidential system, scholars have transferred the MSF's core ideas to multiple issue areas, policy stages, and political systems. However, what has been lacking so far is a thorough discussion of the MSF's travelling capacity to nondemocratic forms of government. Building on a brief summary of the MSF's main ideas, this article discusses the challenges that policy-making in autocracies poses for MSF applications and ways to adapt it to the peculiarities that are typical for these regimes. The article focuses on the agenda-setting stage in which formal institutions are less important and introduces falsifiable hypotheses explaining agenda change. Due to tremendous differences regarding the organization of the decision-making process in autocratic regimes, the article only sketches out how the MSF could be adapted to explain policy change in this institutional setting. The article concludes with a discussion of whether the MSF is stretched too far by applying it to nondemocratic systems. It turns out that in theoretical and conceptual terms, the MSF travels surprisingly well to these systems.

Geographic disparities in heart transplantation persist under the new allocation policy.

BACKGROUND: This study evaluated the impact of the 2018 heart allocation policy change on geographic disparities in United States orthotopic heart transplantation (OHT). METHODS: The United Network for Organ Sharing registry was queried to measure geographic disparity in OHT rates between pre-policy and post-policy change eras. We performed multilevel Poisson regression to measure region-level OHT rates. We derived an allocation priority-adjusted median incidence rate ratio (MIRR) for each policy era, a measure of median change in OHT rates between regions. RESULTS: 5958.78 waitlist person-years were analyzed, comprising 6596 OHT procedures (3890 pre-policy and 2706 post-policy). Median region-level OHT rate was .94 transplants/person-years before and 1.51 transplants/person-years after the policy change (P < .001). The unadjusted OHT MIRR across regions was 1.29 (95% CI 1.00-1.50) pre-policy change and 1.17 (95% CI 1.00-1.43) post-policy change, suggesting that the region-related variance in OHT rates decreased under the new allocation. After adjustment for allocation priority risk factors, the MIRR pre-policy change was 1.13 (95% CI 1.01-1.32) and post-policy change was 1.15 (95% CI 1.00-1.35). CONCLUSIONS: Geography accounts for ∼10% of the disparity among United States OHT rates. Despite broader heart sharing, the updated allocation policy did not substantially alter the existing geographic disparities among OHT recipients.

Becoming a resident in a high demanded medical specialty: an unequal race? Evidence from the Spanish resident market.

BACKGROUND: Gender occupational segregation in medicine is associated with several undesired consequences such as earnings disparity, shortages of specialists or lower quality of care among others. This paper focuses on the persistent gender gap observed in the most popular specialties of the Spanish resident market. In particular, it explores the role of the specialty allocation system in perpetuating the occupational segregation. For that purpose, this paper studies the effect of a policy change in the ranking system that determines doctors' specialty choice order. The change increased the competitiveness of the process by increasing the weight of an entry examination from 75% to 90%, in detriment of doctors' grade point average that decreased from 25% to 10%. Findings from previous literature suggest that that male and female doctors might have reacted differently to the increased competitiveness of the process. METHODS: Data come from administrative records of doctors' specialty choices for the years 2013 and 2015 and they are used to compute the difference between doctors' pre and post-change ranking positions. Then, differences in the distribution of rank differences between male and female doctors are tested by means of parametric (T-test) and non-parametric (Wilcoxon rank) approaches. RESULTS: Results show that the policy change has overall favoured male doctors. On average, female doctors lose ranking positions, with respect to the position they would have achieved with the old weights, whilst male doctors gain positions. The differences are more pronounced in the top half of the ranking distribution, meaning that female doctors on average have reduced their probability of accessing the most demanded specialties. CONCLUSIONS: The objective of the policy was the enhancement of the prospects of Spanish-graduate doctors with respect to international graduates by giving more weight to the less prone to bias examination scores. Nonetheless, the change have had the unintended consequence of reducing the probability of female doctors accessing highly demanded specialties and thus exacerbating the gender gap. The allocation system needs revision to make it accountable for the actual role of doctors in society.

Changes in multiorgan heart transplants following the 2018 allocation policy change.

BACKGROUND: This study evaluated the impact of the heart allocation policy change in 2018 on the characteristics and outcomes of multiorgan transplants involving heart allografts. METHODS: Adults undergoing multiorgan heart transplantation from 2010 to 2020 were identified from the United Network for Organ Sharing (UNOS) registry. Transplants were stratified into occurring before versus after the October 2018 heart allocation change. The primary outcome was 1-year survival following transplantation. A Cox proportional hazards model was used to evaluate the risk-adjusted effect of the allocation policy change on outcomes between cohorts. RESULTS: A total of 1832 patients underwent multiorgan heart transplantation during the study period with 245 (13.37%) undergoing heart-lung transplantation, 244 (13.32%) undergoing heart-liver transplantation, and 1343 (73.31%) undergoing heart-kidney transplantation. There was a higher utilization of temporary MCSDs as well as longer ischemic times for all three types of transplantation following the policy change. Heart-lung and heart-liver recipients had a similar 1-year survival before and after the policy change (each p > .05). Renal failure requiring dialysis (29.5% vs. 39.4%, p = .001) as well as 1-year survival (88% vs. 82%; log-rank p = .01) were worse in the heart-kidney cohort after the organ allocation system modification. CONCLUSIONS: This study demonstrates similar trends in multiorgan transplants as has been observed in isolated heart transplants following the allocation change, including more frequent utilization of temporary mechanical support and longer ischemic times. Although outcomes have remained comparable in the new allocation era with heart-lung and heart-liver transplants, heart-kidney recipients have a worse 1-year survival following the change.

State and local pressures drive plastic pollution compliance strategies.

Environmental harm from plastic pollution partly results from compliance failure at the individual level. Three prevalent non-compliant motivations for polluting plastics include economic gains, ignorance of the rules and unlikely penalization from inadequately enforced rules. Given compliance is primarily the responsibility of local waste management, we conducted interviews to gain insights to the factors driving changes in the crucial on-ground controls of plastic pollution. We expand on non-compliant motivations and provide a theoretical framework to test the aforementioned. We show that compliance strategies are strongly driven by state judicial and economic controls, specifically new plastic legislation and levies. Furthermore, the priorities of waste managers and the socio-economics and population density of their constituents drove changes in local management efforts. Our findings support the view that the growing global attention on plastic pollution shapes not only what happens at a state level, but also importantly on-ground at the local level.
