Background: In 2013 Swiss health authorities implemented annual hospital caseload requirements (CR) for five areas of visceral surgery. We assess the impact of the implementation of CR on indication for surgery in esophageal, pancreatic and rectal cancer.

Materials And Methods: Retrospective analysis of national registry data of all inpatient admissions between January 1st 2005 and December 31st 2015. Primary end-point was the age-adjusted resection rate for esophageal, pancreatic and rectal cancer among patients with at least one cancer-specific hospitalization per year. We calculated age-adjusted rate ratios for period effects before and after implementation of CR and odds ratios (OR) based on a generalized estimation equation. A relative increase of 5% in age-adjusted relative risk was set a priori as relevant from a health policy perspective.

Results: Age-adjusted resection rates before and after the implementation of CR were 0.12 and 0.13 (Relative Risk [RR] 1.08; 95%-Confidence Interval [CI] 0.85-1.36) in esophageal cancer, 0.22 and 0.26 (RR 1.17; 95%-CI 0.85-1.58) in pancreatic cancer and 0.38 and 0.43 (RR 1.14; 95%-CI 0.99-1.30) in rectal cancer. In adjusted models OR for resection after the implementation of CR were 1.40 (95%-CI 1.24-1.58) in esophageal cancer, 1.05 (95%-CI 0.96-1.15) in pancreatic cancer and 0.92 (95%-CI 0.87-0.97) in rectal cancer.

Conclusion: Implementation of CR was associated with an increase of resection rates above the a priori set margins in all resections groups. In adjusted models, odds for resection were significantly higher for esophageal cancer, while they remained unchanged for pancreatic and decreased for rectal cancer.

Analysis of inappropriate prescribing in elderly patients of the Swiss HIV Cohort Study reveals gender inequity.

J Antimicrob Chemother 2021 02;76(3):758-764

University of Basel, Basel, Switzerland.

Background: The extent of inappropriate prescribing observed in geriatric medicine has not been thoroughly evaluated in people ageing with HIV. We determined the prevalence of and risk factors for inappropriate prescribing in individuals aged ≥75 years enrolled in the Swiss HIV Cohort Study.

Methods: Retrospective review of medical records was performed to gain more insights into non-HIV comorbidities. Inappropriate prescribing was screened using the Beers criteria, the STOPP/START criteria and the Liverpool drug-drug interactions (DDIs) database.

Results: For 175 included individuals, the median age was 78 years (IQR 76-81) and 71% were male. The median number of non-HIV comorbidities was 7 (IQR 5-10). The prevalence of polypharmacy and inappropriate prescribing was 66% and 67%, respectively. Overall, 40% of prescribing issues could have deleterious consequences. Prescribing issues occurred mainly with non-HIV drugs and included: incorrect dosage (26%); lack of indication (21%); prescription omission (drug not prescribed although indicated) (17%); drug not appropriate in elderly individuals (18%) and deleterious DDIs (17%). In the multivariable logistic regression, risk factors for prescribing issues were polypharmacy (OR: 2.5; 95% CI: 1.3-4.7), renal impairment (OR: 2.7; 95% CI: 1.4-5.1), treatment with CNS-active drugs (OR: 2.1; 95% CI: 1.1-3.8) and female sex (OR: 8.3; 95% CI: 2.4-28.1).

Conclusions: Polypharmacy and inappropriate prescribing are highly prevalent in elderly people living with HIV. Women are at higher risk than men, partly explained by sex differences in the occurrence of non-HIV comorbidities and medical care. Medication reconciliation and periodic review of prescriptions by experienced physicians could help reduce polypharmacy and inappropriate prescribing in this vulnerable, growing population.

Prevalence of potential drug-drug interactions in patients of the Swiss HIV Cohort Study in the era of HIV integrase inhibitors.

Clin Infect Dis 2020 Jul 8. Epub 2020 Jul 8.

Division of Infectious Diseases & Hospital Hygiene, University Hospital Basel and University of Basel, Basel, Switzerland.

Background: Prevalence of potential drug-drug interactions (PDDIs) between antiretroviral drugs (ARVs) and comedications was high in 2008 in a Swiss HIV Cohort Study (SHCS) survey. We reassessed the prevalence of PDDIs in the era of HIV integrase inhibitors (INIs), characterized by more favorable interaction profiles.

Methods: The prevalence of PDDIs in treated HIV positive individuals was assessed for the period: 01-12/2018 by linkage of the Liverpool HIV drug interactions and SHCS databases. PDDIs were categorized as harmful (red flagged), of potential clinical relevance (amber flagged) or of weak clinical significance (yellow flagged).

Results: In 9'298 included individuals, median age was 51 years (IQR 43; 58), and 72% were males. Individuals received unboosted INIs (40%), boosted ARVs (30%), and non-nucleoside reverse transcriptase inhibitors (NNRTIs) (32%) based regimens. In the entire cohort, 68% received > 1 comedication, 14% had polypharmacy (> 5 comedications) and 29% had > 1 PDDI. Among individuals with comedication, the prevalence of combined amber and yellow PDDIs was 43% (33% amber - mostly with cardiovascular drugs - and 20% yellow flagged PDDIs) compared to 59% in 2008. Two percent had red flagged PDDIs (mostly with corticosteroids), the same as in the 2008 survey. Compared to 2008, fewer individuals received boosted ARVs (-24%) and NNRTIs (-13%) but the use of comedications was higher.

Conclusions: Prevalence of PDDIs was lower with more widespread use of INIs in 2018 than in 2008. Continued use of boosted regimens and increasing needs for comedications in this aging population impeded lower rates of PDDIs.

Risk of Emergency Surgery or Death After Initial Nonoperative Management of Complicated Diverticulitis in Scotland and Switzerland.

JAMA Surg 2020 07;155(7):600-606

Academic Coloproctology, University of Edinburgh/Western General Hospital, Edinburgh, United Kingdom.

Importance: National guidelines on interval resection for prevention of recurrence after complicated diverticulitis are inconsistent. Although US and German guidelines favor interval colonic resection to prevent a perceived high risk of recurrence, UK guidelines do not.

Objectives: To investigate patient management and outcomes after an index inpatient episode of nonoperatively managed complicated diverticulitis in Switzerland and Scotland and determine whether interval resection was associated with the rate of disease-specific emergency surgery or death in either country.

Design, Setting, And Participants: This secondary analysis of anonymized complete national inpatient data sets included all patients with an inpatient episode of successfully nonoperatively managed complicated diverticulitis in Switzerland and Scotland from January 1, 2005, to December 31, 2015. The 2 countries have contrasting health care systems: Switzerland is insurance funded, while Scotland is state funded. Statistical analysis was conducted from February 1, 2018, to October 17, 2019.

Main Outcomes And Measures: The primary end point defined a priori before the analysis was adverse outcome, defined as any disease-specific emergency surgical intervention or inpatient death after the initial successful nonsurgical inpatient management of an episode of complicated diverticulitis, including complications from interval elective surgery.

Results: The study cohort comprised 13 861 inpatients in Switzerland (6967 women) and 5129 inpatients in Scotland (2804 women) with an index episode of complicated acute diverticulitis managed nonoperatively. The primary end point was observed in 698 Swiss patients (5.0%) and 255 Scottish patients (5.0%) (odds ratio, 0.98; 95% CI, 0.81-1.19). Elective interval colonic resection was undertaken in 3280 Swiss patients (23.7%; median follow-up, 53 months [interquartile range, 24-90 months]) and 231 Scottish patients (4.5%; median follow-up, 57 months [interquartile range, 27-91 months]). Death after urgent readmission for recurrent diverticulitis occurred in 104 patients (0.8%) in Switzerland and 65 patients (1.3%) in Scotland. None of the investigated confounders had a significant association with the outcome apart from comorbidity.

Conclusions And Relevance: This study found no difference in the rate of adverse outcome (emergency surgery and/or inpatient death) despite a 5-fold difference in interval resection rates.
