Background/aimsTo assess surgical patterns in ophthalmology by subspecialty in the USA.MethodsOphthalmic surgeons were categorised as comprehensive/subspecialist based on billed procedures in the 2017–2018 Medicare Provider Utilization and Payment Data. Poisson regression models assessed factors associated with physicians performing surgeries in the core domain (eg, cataract extractions) and subspecialty domain. Models were adjusted for provider gender, time since graduation, geographical region, practice setting and hospital affiliation.ResultsThere were 10 346 ophthalmic surgeons, 74.7% comprehensive and 25.3% subspecialists. Cataract extractions were performed by 6.0%, 9.9%, 21.0%, 88.1% and 95.3% of specialists in surgical retina, neuro-ophthalmology/paediatrics, oculoplastics, glaucoma and cornea, respectively. Retina specialists were more likely to perform cataract surgery if they were 20–30 or>30 years in practice (relative risk: 2.20 (95% CI: 1.17 to 4.12) and 3.74 (95% CI: 1.80 to 7.76), respectively) or in a non-metropolitan setting (3.78 (95% CI: 1.71 to 8.38)). Among oculoplastics specialists, male surgeons (2.71 (95% CI: 1.36 to 5.42)), those in practice 10–20 years or 20–30 years (1.93 (95% CI: 1.15 to 3.26) and 1.91 (95% CI: 1.11 to 3.27), respectively) and in non-metropolitan settings (3.07 (95% CI: 1.88 to 5.02)) were more likely to perform cataract surgery. Only 26 of the 2620 subspecialists performed surgeries in two or more subspecialty domains.ConclusionsThere is a trend towards surgical subspecialisation in ophthalmology in the USA whereby some surgeons focus their surgical practice on subspecialty procedures and rarely perform surgeries in the core domain.

Core Domain Set

IntroductionThere is a lack of harmonising measures for clinical trials on total joint replacement (TJR) that would allow for results from TJR studies to be compared or pooled. The Outcome Measures in Rheumatology (OMERACT) TJR core domain set is already endorsed among patients and physicians in the USA and Australia. Physiotherapists use different types of measurements compared to orthopaedic surgeons while both make substantial contributions to research in the field of TJR. To achieve consensus on core measurements sets, patients, physiotherapists and orthopaedic surgeons need to achieve consensus on the core domains for TJR trials.Methods and analysisFor this multistage study, first, the OMERACT TJR core domain set survey will be translated to German and validated according to WHO guidelines. Next, the TJR core domain set will be considered for endorsement in different German stakeholder groups including patients, physiotherapists and orthopaedic surgeons.Ethics and disseminationEthical approval for this protocol was given by the ethics committee of the Brandenburg University of Technology Cottbus—Senftenberg (BTU—CS, EK 2019—2). This article is based on the protocol version 2.5 from 6 May 2020. Anonymous data will be presented only. We will publish the results in peer-reviewed publications and at international conferences.Trial registration numberGerman Clinical Trials Registry (DRKS00016015).

The Impact

Purpose Cryptocurrencies have been used to commit various offences, but enforcement efforts remain underdeveloped relative to the value of these crimes. This paper aims to examine factors associated with outcomes of US-based cryptocurrency financial crime prosecutions. Design/methodology/approach The authors studied the 37 resolved cryptocurrency-based financial crime cases in the USA to date, exploring the impact of offence, defendant and evidence characteristics on the mode of disposition and penalties. The authors used bivariate analyses and logistic regression models to determine relationships among these variables. Findings The presence of individual defendants only (rather than a corporate defendant or combination thereof) and the use of only a cryptocurrency other than Bitcoin in committing a crime each made a case less likely to be resolved by dismissal, trial or summary or default judgement. Originality/value This paper is the first to examine variables contributing to financial crime prosecution outcomes and has implications for prosecutorial decision-making, resource allocation and the prevention and detection of financial offences involving cryptocurrencies.

Subject. The military-industrial complex is one of the core industries in any economy. It ensures both the economic and global security of the State. However, the economic security of MIC enterprises strongly depends on the State and other stakeholders. Objectives. We examine key factors of corporate culture in terms of theoretical and practical aspects. The article identifies the best implementation of corporate culture that has a positive effect on the corporate security in the MIC of the USA, the United Kingdom, the European Union, Japan ans China. Methods. The study employs dialectical method of research, combines the historical and logic unity, structural analysis, traditional techniques of economic analysis and synthesis. Results. We performed the comparative analysis of corporate culture models and examined how they are used by the MIC corporations with respect to international distinctions. Conclusions and Relevance. The State is the main stakeholder of the MIC corporations, since it acts as the core customer represented by the military department. It regulates and controls operations. The State is often a major shareholder of such corporations. Employees are also important stakeholders. Hence, trying to satisfy stakeholders' needs by developing the corporate culture, corporations mitigate their key risks and enhance their corporate security.

Aim: To identify demographic predictors of patients who miss oncology follow-up, considering that missed follow-up has not been well studies in cancer patients. Methods: Patients with solid tumors diagnosed from 2007 to 2016 were analyzed (n = 16,080). Univariate and multivariable logistic regression models were constructed to examine predictors of missed follow-up. Results: Our study revealed that 21.2% of patients missed ≥1 follow-up appointment. African–American race (odds ratio [OR] 1.33; 95% CI: 1.17–1.51), Medicaid insurance (OR 1.59; 1.36–1.87), no insurance (OR 1.66; 1.32–2.10) and rural residence (OR 1.78; 1.49–2.13) were associated with missed follow-up. Conclusion: Many cancer patients miss follow-up, and inadequate follow-up may influence cancer outcomes. Further research is needed on how to address disparities in follow-up care in high-risk patients.

AbstractThe factors associated with chronic opioid therapy (COT) in patients with HIV is understudied. Using Medicaid data (2002–2009), this retrospective cohort study examines COT in beneficiaries with HIV who initiated standard combination anti-retroviral therapy (cART). We used generalized estimating equations on logistic regression models with backward selection to identify significant predictors of COT initiation. COT was initiated among 1014 out of 9615 beneficiaries with HIV (male: 10.4%; female: 10.7%). Those with older age, any malignancy, Hepatitis C infection, back pain, arthritis, neuropathy pain, substance use disorder, polypharmacy, (use of) benzodiazepines, gabapentinoids, antidepressants, and prior opioid therapies were positively associated with COT. In sex-stratified analyses, multiple predictors were shared between male and female beneficiaries; however, chronic obstructive pulmonary disease, liver disease, any malignancy, and antipsychotic therapy were unique to female beneficiaries. Comorbidities and polypharmacy were important predictors of COT in Medicaid beneficiaries with HIV who initiated cART.

AbstractGeographic variation of paediatric tonsillectomy, with or without adenoidectomy, (A/T) has been described since the 1930s until today but no studies have investigated the factors associated with this variation. This study described the geographical distribution of paediatric A/T across the state of Victoria, Australia, and investigated area-level factors associated with this variation. We used linked administrative datasets capturing all paediatric A/T performed between 2010 and 2015 in Victoria. Surgery data were collapsed by patient residence to the level of Local Government Area. Regression models were used to investigate the association between likelihood of surgery and area-level factors. We found a 10.2-fold difference in A/T rates across the state, with areas of higher rates more in regional than metropolitan areas. Area-level factors associated with geographic variation of A/T were percentage of children aged 5–9 years (IRR 1.07, 95%CI 1.01–1.14, P = 0.03) and low English language proficiency (IRR 0.95, 95% CI 0.90–0.99, P = 0.03). In a sub-population analysis of surgeries in the public sector, these factors were low maternal educational attainment (IRR 1.09, 95% CI 1.02–1.16, P < 0.001) and surgical waiting time (IRR 0.99635 95% CI 0.99273–0.99997, P = 0.048). Identifying areas of focus for improvement and factors associated with geographic variation will assist in improving equitable provision of paediatric A/T and decrease variability within regions.

Using the matched wife–husband (763) sample from the data collected from Ogbomoso and Iseyin towns in Oyo State, Nigeria, this paper examines factors associated with couples’ fertility intention. The analysis used logistic regression models for predicting the effects of selected socioeconomic background characteristics on a couple’s fertility intention. Results indicate high levels of concurrence among husbands and wives on fertility intention. Where differences exist, husbands are more pronatalists than their wives. About 87% of pairs of partners reported similar fertility preferences. Of these couples, 59·5% wanted more children while only 27·8% reported otherwise. The logistic regression models indicated that a couple’s fertility intention was associated with age, education, place of residence, frequency of television-watching and number of living children. Therefore, programme interventions aimed at promoting fertility reduction in Nigeria should convey fertility regulation messages to both husbands and wives.

e17000 Background: Disabled patients are a unique minority population that may have lower literacy levels and difficulty communicating with physicians. Furthermore, their knowledge for cancer prevention recommendations is unknown. Herein, we aim to compare prostate-specific antigen (PSA) testing rates and associated predictors among disabled men and non-disabled men in the USA. Methods: We performed a cross-sectional study utilizing the Health Information National Trends Survey (HINTS) to analyze factors predicting PSA testing rates in men with disabilities (disabled, deaf, blind). Multivariable logistic regression models were used to determine clinically significant predictors of PSA testing in men with disabilities compared to that of the healthy cohort. Results: A total of 782 (14.6%) disabled men were compared to 4,569 (85.4%) non-disabled men. Disabled men were older with a mean age of 65.0 ± 14.2 vs. 55.0 ± 15.9 years (p < 0.001). On multivariable analysis, after adjusting for all available confounders including race, age, geographical region, survey year, marital status, health insurance, healthcare provider, amongst others, men with any disability were less likely to undergo PSA screening (OR 0.772, 95% CI 0.623-0.956, p = 0.018). Variables associated with increased PSA screening rates included age, having a healthcare provider or health insurance, and living with a partner. Although prostate cancer detection rates were shown to be higher among disabled men, this did not reach statistical significance. Conclusions: Our data suggests that significant inequalities in PSA screening exist among men with disabilities in the USA, with disabled men, especially the deaf and the blind, being less likely to be offered PSA screening. There is a clear need to implement strategies to reduce existing gaps in the care of disabled men and strive to reach equality in PSA screening in this unique population.
