The Changing Nature of Scientific Sharing and Withholding in Academic Life Sciences Research: Trends From National Surveys in 2000 and 2013.

ABSTRACT: Since 2000, federal funders and many journals have established policies requiring more open sharing of data and materials post-publication, primarily through online supplements and third-party repositories. This study examined changes in sharing and withholding practices among academic life scientists, particularly geneticists, between 2000 and 2013.In 2000 and 2013, the authors surveyed separate samples of 3,000 academic life scientists at the 100 U.S. universities receiving the most National Institutes of Health funding. Respondents were asked to estimate the number of requests for information, data, and materials they made to and received from other academic researchers in the past three years. They were also asked about potential consequences of sharing and withholding.Response rates were 63.9% (1,849/2,893) in 2000 and 40.8% (1,165/2,853) in 2013. Proportions of faculty in 2000 and 2013 who received, denied, made, or were denied at least one request were not statistically different. However, the total volume of requests received from or made to other scientists dropped substantially (19.4 received in 2000 versus 10.8 in 2013, P < .001; 8.4 made in 2000 versus 6.6 in 2013, P < .001). Faculty in 2013 also made an average of 8.4 requests to third-party repositories. Researchers in 2013 were less likely to report sharing resulted in new research or collaborations.The results show a dramatic shift in sharing mechanisms, away from a peer-to-peer sharing model toward one based on central repositories. This may increase efficiency, but collaborations may suffer if personal communication among scientists is deemphasized.

Project description:ObjectivesGuidelines for the use of drugs for type 2 diabetes mellitus (T2DM) have changed since 2000, and new classes of drug have been introduced. Our aim was to describe how drug choice at initiation and first stage of intensification have changed over this period, and to what extent prescribing was in accord with clinical guidelines, including adherence to recommendations regarding kidney function.DesignRepeated cross-sectional study.SettingUK electronic primary care health records from the Clinical Practice Research Datalink.ParticipantsAdults initiating treatment with a drug for T2DM between January 2000 and July 2017.Primary and secondary outcome measuresThe primary outcomes were the proportion of each class of T2DM drug prescribed for initiation and first-stage intensification in each year. We also examined drug prescribing by kidney function and country within the UK.ResultsOf 280 241 people initiating treatment with T2DM drugs from 2000 to 2017, 73% (204 238/280 241) initiated metformin, 15% (42 288/280 241) a sulfonylurea, 5% (12 956/280 241) with metformin and sulfonylurea dual therapy and 7% (20 759/280 241) started other options. Clinicians have increasingly prescribed metformin at initiation: by 2017 this was 89% (2475/2778) of drug initiations. Among people with an estimated glomerular filtration rate of ?30?mL/min/1.73?m2, the most common drug at initiation was a sulfonylurea, 58% (659/1135). In 2000, sulfonylureas were the predominant drug at the first stage of drug intensification (87%, 534/615) but by 2017 this fell to 30% (355/1183) as the use of newer drug classes increased. In 2017, new prescriptions for dipeptidyl peptidase-4 inhibitors (DPP4i) and sodium/glucose cotransporter-2 inhibitors (SGLT2i) accounted for 42% (502/1183) and 22% (256/1183) of intensification drugs, respectively. Uptake of new classes differs by country with DPP4is and SGLT2is prescribed more in Northern Ireland and Wales than England or Scotland.ConclusionsOur findings show markedly changing prescribing patterns for T2DM between 2000 and 2017, largely consistent with clinical guidelines.

Project description:ObjectiveQuantify differential attainment by ethnicity in undergraduate medical assessments and evaluate whether institutional efforts to reduce the attainment gap have had impact.DesignObservational cohort study.SettingA single UK MBBS medical programme.ParticipantsPseudonymised data of adults aged ≥18 years enrolled in one of the UK MBBS medical programmes between 2012 and 2018. Ethnicity was self-declared during enrolment as White, Asian, Black, mixed and other.Main outcome measureModule mark (distinction, merit, pass, fail) graded according to a variety of assessments, including single best answer examinations, objective structured clinical examinations and coursework submissions. All modular assessments are graded as a percentage. Logistic regression models were used to calculate relative risk ratio to study the association between ethnicity and attainment gap over a calendar and scholastic year. Models were adjusted for age, gender, social deprivation and scholastic year of study.Results3714 student records were included. In the sample, 2134 students (57%) were non-white. The proportion of non-white students increased from 2007 (49%) to 2018 (70%). Mean age was 18 (IQR 18-21) and 56.6% were females. Higher proportion of non-white students 218 (24.8%) were from more deprived backgrounds versus white 76 (14.8%). Compared with non-white, there were no significant differences in the proportion of students failing assessments. However, white students were more likely to achieve merit (relative risk ratio 1.29 (95% CI 1.08 to 1.45)) or distinction (1.69 (95% CI 1.37 to 2.08)). Differences in attainment gap have remained unchanged over time, and for black students, attainment gap grew between their first and final year of study.ConclusionA similar proportion (97%) of non-white and white students had a passing score, but attainment gap for higher grades persists over years despite widespread efforts in medical schools to diminish the attainment gap linked to ethnicity. Our findings are from a single institution, thus affecting generalisability.
