This study examines a diverse set of nearly 100 private institutions that adopted test-optional undergraduate admissions policies between 2005–2006 and 2015–2016. Using comparative interrupted time series analysis and difference-in-differences with matching, I find that test-optional policies were associated with a 3% to 4% increase in Pell Grant recipients, a 10% to 12% increase in first-time students from underrepresented racial/ethnic backgrounds, and a 6% to 8% increase in first-time enrollment of women. Overall, I do not detect clear evidence of changes in application volume or yield rate. Subgroup analyses suggest that these patterns were generally similar for both the more selective and the less selective institutions examined. These findings provide evidence regarding the potential—and the limitations—of using test-optional policies to improve equity in admissions.

BackgroundThere is strong evidence from many settings that tobacco tax rises which increase prices reduce tobacco consumption, but only limited evidence from Indigenous settings.MethodsWe analysed 3 years (2016–2018) of weekly sales data from 32 stores in remote Aboriginal communities. We used interrupted time series analysis to estimate the immediate impact of the price rice following annual 12.5% tobacco tax rises on sales on (A) stick equivalents of tobacco and (B) fruit and vegetables (kg) per $A1000 of grocery sales, and on the trend in sales between price rises.ResultsWe detected 5.8% and 8.2% immediate declines in tobacco sales following the price rises associated with annual 12.5% tax rises in 2016 and 2018, and a non-significant decline (1.6%) following the 2017 tax rise. Decreased sales were mainly driven by declines in mainstream and premium factory-made cigarettes. Fruit and vegetable sales did not change at the time of tobacco price rises.ConclusionFor the first time, we demonstrated evidence of price-sensitivity and the immediate impact of price rises from tobacco tax rises on tobacco sales in remote Aboriginal communities. We acknowledge that Australia already has very high tobacco taxation and prices, but recommend further increases to the taxation of roll-your-own (RYO) tobacco to prevent smokers and industry using cheaper RYO cigarettes to undermine this impact of high tobacco taxes and prices.

Objectives: The Getting It Right First Time programme was set up to reduce unwarranted variation in healthcare practice and outcomes in England. The aim of this study was to investigate early changes in practice in urology based on the recommendations made. Subjects and methods: Data were extracted from the Hospital Episodes Statistics database from January 2014 to December 2019. The dates of visits by members of the Getting It Right First Time team were taken as the intervention point. Interrupted time series analysis was used to identify trends pre and post intervention. Results: Following the Getting It Right First Time visits, there was evidence of a significant increase in the proportion of patients seen as day cases for transurethral resection of bladder tumour and decreased use of stents and increased use of ureteroscopy or extracorporeal shock wave lithotripsy on first presentation with ureteric stones. However, there was no significant change in waiting times for surgery to treat patients who had an emergency presentation with urinary retention. Conclusions: There is evidence that the recommendations made are already having an impact on clinical practice. The reasons why some recommendations appear to be harder to implement requires further investigation. Level of evidence: 2b

Abstract Background The Opioid Reduction Act (SB 273) took effect in West Virginia in June 2018. This legislation limited ongoing chronic opioid prescriptions to 30 days’ supply, and first-time opioid prescriptions to 7 days’ supply for surgeons and 3 days’ for emergency rooms and dentists. The purpose of this study was to determine the effect of this legislation on reducing opioid prescriptions in West Virginia, with the goal of informing future similar policy efforts. Methods Data were requested from the state Prescription Drug Monitoring Program (PDMP) including overall number of opioid prescriptions, number of first-time opioid prescriptions, average daily morphine milligram equivalents (MME) and prescription duration (expressed as “days’ supply”) given to adults during the 64 week time periods before and after legislation enactment. Statistical analysis was done utilizing an autoregressive integrated moving average (ARIMA) interrupted time series analysis to assess impact of both legislation announcement and enactment while controlling secular trends and considering autocorrelation trends. Benzodiazepine prescriptions were utilized as a control. Results Our analysis demonstrates a significant decrease in overall state opioid prescribing as well as a small change in average daily MME associated with the date of the legislation’s enactment when considering serial correlation in the time series and accounting for pre-intervention trends. There was no such association found with benzodiazepine prescriptions. Conclusion Results of the current study suggest that SB 273 was associated with an average 22.1% decrease of overall opioid prescriptions and a small change in average daily MME relative to the date of legislative implementation in West Virginia. There was, however, no association of the legislation on first-time opioid prescriptions or days’ supply of opioid medication, and all variables were trending downward prior to implementation of SB 273. The control demonstrated no relationship to the law.

The Status

Race-conscious admissions policies are politically controversial yet pragmatically effective for improving access for people of color to selective U.S. colleges and universities. While the admissions policies of elite institutions get the most political, scholarly, and media attention, little is known about the use of affirmative action in admissions across the broader field of selective higher education. Based on analysis of longitudinal panel data of almost 1,000 selective status colleges and universities, we find a dramatic shift in stated organizational policy starting in the mid-1990s. In 1994, 60% of institutions publicly declared that they considered race in undergraduate admissions; by 2014, just 35% did. Yet there is substantial variation depending on schools’ status (competitiveness) and sector (public or private). Notably, race-conscious admissions remain the stated organizational policy of almost all of the most elite public and private institutions. The retreat from race-conscious admissions occurs largely among schools relatively lower in the status hierarchy: very competitive public institutions and competitive public and private institutions. These patterns are not explained by the implementation of state-level bans. The findings suggest that both the diversity imperative and the diffuse impact of the anti-affirmative action movement are not consistent across strata of American higher education.

Objectives To review the evidence of the effects of centralization of cancer surgery on postoperative mortality. Methods We searched Medline, Embase, Cinahl, Cochrane and Scopus (up to November 2019) for studies that (i) assessed the effects of centralization of cancer surgery policies on in-hospital or 30-day mortality, or (ii) described changes in both postoperative mortality for a surgical intervention and degree of centralization using reduction in the number of hospitals or increases in the proportion of patients undergoing cancer surgery at high volume hospitals as proxy. PRISMA guidelines were followed. We estimated pooled odds ratios (OR) and conducted meta-regression to assess the relationship between degree of centralization and mortality. Results A total of 41 studies met our inclusion criteria of which 15 evaluated the effect of centralization policies on postoperative mortality after cancer surgery and 26 described concurrent changes in the degree of centralization and postoperative mortality. Policy evaluation studies mainly used before-after designs (n = 13) or interrupted time series analysis (n = 2), mainly focusing on pancreatic, oesophageal and gastric cancer. All but one showed some degree of reduction in postoperative mortality, with statistically significant effects demonstrated by six studies. The pooled odds ratio for centralization policy effect was 0.68 (95% Confidence interval: 0.54–0.85; I2 = 80%). Meta-regression analysis of the 26 descriptive studies found that an increase of the proportion of patients treated at high volume hospitals was associated with greater reduction in postoperative mortality. Conclusions Centralization of cancer surgery is associated with reduced postoperative mortality. However, existing evidence tends to be of low quality and estimates of the effect size are likely inflated. There is a need for prospective studies using more robust approaches, and for centralization efforts to be accompanied by well-designed evaluations of their effectiveness.

Abstract Background Service reconfiguration of inpatient services in a hospital includes complete and partial closure of all emergency inpatient facilities. The “natural experiment” of service reconfiguration may give insight into drivers for emergency admissions to hospital. This study addressed the question does the prevalence of emergency admission to hospital for children change after reconfiguration of inpatient services? Methods There were five service reconfigurations in Scottish hospitals between 2004 and 2018 where emergency admissions to one “reconfigured” hospital were halted (permanently or temporarily) and directed to a second “adjacent” hospital. The number of emergency admissions (standardised to /1000 children in the regional population) per month to the “reconfigured” and “adjacent” hospitals was obtained for five years prior to reconfiguration and up to five years afterwards. An interrupted time series analysis considered the association between reconfiguration and admissions across pairs comprised of “reconfigured” and “adjacent” hospitals, with adjustment for seasonality and an overall rising trend in admissions. Results Of the five episodes of reconfiguration, two were immediate closure, two involved closure only to overnight admissions and one with overnight closure for a period and then closure. In “reconfigured” hospitals there was an average fall of 117 admissions/month [95% CI 78, 156] in the year after reconfiguration compared to the year before, and in “adjacent” hospitals admissions rose by 82/month [32, 131]. Across paired reconfigured and adjacent hospitals, in the months post reconfiguration, the overall number of admissions to one hospital pair slowed, in another pair admissions accelerated, and admission prevalence was unchanged in three pairs. After reconfiguration in one hospital, there was a rise in admissions to a third hospital which was closer than the named “adjacent” hospital. Conclusions There are diverse outcomes for the number of emergency admissions post reconfiguration of inpatient facilities. Factors including resources placed in the community after local reconfiguration, distance to the “adjacent” hospital and local deprivation may be important drivers for admission pathways after reconfiguration. Policy makers considering reconfiguration might consider a number of factors which may be important determinants of admissions post reconfiguration.

The Impact

Aim: The aim of this study is to analyse the potential impact from the financial crisis (onset in 2009) on suicide rates in Denmark. The hypothesis is that the global financial crisis raised unemployment which leads to raising the suicide rate in Denmark and that the impact is most prominent in men. Method: This study used an ecological study design, including register data from 2001 until 2016 on unemployment, suicide, gender and calendar time which was analysed using Poisson regression models and interrupted time series analysis. Results: The correlation between unemployment and suicide rates was positive in the period and statistically significant for all, but at a moderate level. A dichotomised version of time (calendar year) showed a significant reduction in the suicide rate for women (incidence rate ratio 0.87, P=0.002). Interrupted time series analysis showed a significant decreasing trend for the overall suicide rate and for men in the pre-recession period, which in both cases stagnated after the onset of recession in 2009. The difference between the genders’ suicide rate changed significantly at the onset of recession, as the rate for men increased and the rate for women decreased. Discussion: The Danish social welfare model might have prevented social disintegration and suicide among unemployed, and suicide prevention programmes might have prevented deaths among unemployed and mentally ill individuals. Conclusions: We found some indications for gender-specific differences from the impact of the financial crises on the suicide rate. We recommend that men should be specifically targeted for appropriate prevention programmes during periods of economic downturn.
