Abstract
BACKGROUND Preclinical studies suggested that drugs that functionally inhibit acid sphingomyelinase (FIASMA)may enhance immune cell longevity and potentially offer protection against infections. Many antidepressants have shown FIASMA activity. METHODS We conducted a cohort study using primary-care data from the UK-based Clinical Practice Research Datalink (2000-2021). We assessed the association of composite diagnosed acute infections in new users of fluoxetine, sertraline, paroxetine, or venlafaxine aged 18-80 years compared to citalopram. We compared SARS-CoV-2 infections between groups in a secondary analysis. We estimated incidence rates (IR) and IR ratios (IRR) of acute infections in four pairwise comparisons using negative binomial regression. We applied propensity score (PS) fine stratification to control for confounding. RESULTS In the PS-weighted cohorts, we included 353,138 fluoxetine, 222,463 sertraline, 69,963 paroxetine, 32,608 venlafaxine, and between 515,996 and 516,583 new citalopram users. PS-weighted IRs ranged between 76.8 acute infections /1000 person-years (py) (sertraline) and 98.9 infections/1000 py (citalopram). We observed PS-weighted IRRs around unity for paroxetine (0.97, 95 % CI, 0.95-1.00), fluoxetine (0.94, 95 % CI, 0.92-0.95), and venlafaxine (0.90, 95 % CI, 0.87-0.94) vs citalopram. Reduced IRR for sertraline vs citalopram (0.84, 95 % CI, 0.82-0.85), became null within subgroups by cohort entry date. In the analysis of SARS-CoV-2 infection, no statistically relevant risk reduction was seen. LIMITATIONS Analysis not limited to patients with diagnosed depression, possible underestimation of infection incidence, and unclear FIASMA activity of citalopram. CONCLUSIONS Fluoxetine, sertraline, paroxetine, and venlafaxine were not associated with a reduced risk of acute infection when compared with the presumably weak FIASMA citalopram.

Abstract
AIMS OF THE STUDY Unlicensed drugs are frequently used in paediatric care. To what extent they are prescribed in hospital care in Switzerland is unclear. Because prescribing errors seem to occur more frequently with unlicensed drugs, we aimed to assess the prevalence of unlicensed drug prescriptions in two study periods (2018 and 2019) at the University Children's Hospital Zurich, compare these periods and investigate whether unlicensed drugs were more prone to prescribing errors than licensed drugs. METHODS We conducted a sub-analysis of a retrospective single-centre observational study and analysed 5,022 prescriptions for a total of 1,000 patients from 2018 and 2019 in paediatric general wards. The rate of unlicensed drugs, consisting of imported or formula drugs, was investigated. The prescriptions from 2019 were further analysed on prescribing errors to see whether errors occurred more often in unlicensed or licensed drug use. RESULTS Of all prescriptions, 10.8% were unlicensed drugs, with around half each being imported and formula drugs. Among all patients, 34% were prescribed at least one unlicensed drug. Younger paediatric patients were prescribed more unlicensed drugs than older paediatric patients (newborns: 15.8% of prescriptions, infants: 13.4%, children: 10.6%, adolescents: 7.1%). Ibuprofen suppositories, midazolam oral solution and gentamicin i.v. solution were the most frequently prescribed imported drugs. Macrogol powder, lisinopril oral suspension and potassium chloride i.v. solution were the most frequently prescribed formula drugs. The most common drug forms in unlicensed use were oral liquid forms and i.v. SOLUTIONS Unlicensed drugs had a significantly higher rate of prescribing errors than licensed drugs (31.6 errors per 100 prescriptions [95% CI: 26.1-37.0] versus 24.3 errors per 100 prescriptions [95% CI: 22.3-26.2], p = 0.024). In particular, formula drugs carried a higher risk (36.4 errors per 100 prescriptions, p = 0.012). CONCLUSIONS Unlicensed drugs are frequently prescribed in this paediatric hospital setting in Switzerland. Around every tenth prescription is an unlicensed drug. Because unlicensed drugs showed a significantly higher rate of prescribing errors, licensed drugs are favourable in terms of medication safety and should be prescribed whenever possible. If no licensed drug is available, imported drugs should be favoured over formula drugs due to lower prescribing error rates. To increase medication safety in paediatrics in Switzerland, efforts are necessary to increase the number of suitable licensed drug formulations for paediatric patients, including developing new innovative drug formulations for children.

Abstract
OBJECTIVES Prescription sequence symmetry analysis (PSSA) is used to detect adverse event signals using administrative claims databases. In this study, we investigated whether PSSA can be applied to gauge the effects of PCV13 vaccination on antibiotic prescription rates in elderly patients. METHODS We studied prescription records of patients aged 65 or older between 1 January 2014 and 31 December 2020, from the Helsana Swiss claims database. PSSA was performed to explore the relationship between 13-valent pneumococcal conjugate vaccine (PCV13) and six antibiotics recommended by the Swiss Society of Infectious Diseases for community-acquired pneumonia treatment (amoxicillin-clavulanate, azithromycin, clarithromycin, doxycycline, levofloxacin, and moxifloxacin), three additional antibiotics (amoxicillin, ciprofloxacin, and fosfomycin), and ten control drugs. RESULTS Amoxicillin-clavulanate, clarithromycin, and levofloxacin were more likely to be prescribed before than after vaccination, for all time windows between 25 and 104 weeks. Adjusted sequence ratio (ASR) values ranged from 0.599 to 0.614, 0.508 to 0.568, and 0.514 to 0.752, respectively. Lower prescription rates after vaccination were also observed for azithromycin (all time windows between 38 and 104 weeks, ASR 0.705-0.739) and moxifloxacin (all time windows between 52 and 104 weeks, ASR 0.658-0.772). PCV13 did not have statistically significant associations with doxycycline, amoxicillin, ciprofloxacin, fosfomycin, or any of the ten controls. DISCUSSION The lower prescription rate of antibiotics for community-acquired pneumonia after vaccination could be attributed to a protective effect of PCV13. This novel application of PSSA can be used to compare the real-world impact of other vaccines on drug consumption.

Abstract
OBJECTIVE To investigate claims patterns for metamizole and other non-opioid analgesics in Switzerland. To characterise users of these non-opioid analgesics regarding sex, age, comedications and canton of residence. METHODS We conducted a retrospective descriptive study using administrative claims data of outpatient prescribed non-opioid analgesics of the Swiss health insurance company Helsana between January 2014 and December 2019. First, we evaluated the number of claims and defined daily doses per year of metamizole, ibuprofen, diclofenac and paracetamol in adults aged 18 years or over. Second, we characterised new users of these non-opioid analgesics in terms of sex, age, claimed comedications and canton of residence. RESULTS From 2014 to 2019, among the investigated non-opioid analgesics, metamizole showed the highest increase in claims (+9545 claims, +50%) and defined daily doses (+86,869 defined daily doses, +84%) per 100,000 adults. Metamizole users had the highest median age (62 years [IQR: 44-77]) compared to ibuprofen (47 years [IQR: 33-62]), diclofenac (57 years [IQR: 43-71]) and paracetamol (58 years [IQR: 39-75]) users. Metamizole users also more frequently claimed proton pump inhibitors, anticoagulants, platelet aggregation inhibitors and antihypertensive drugs than users of other non-opioid analgesics. While metamizole was most frequently claimed in German-speaking regions of Switzerland, ibuprofen and paracetamol were most frequently claimed in the French-speaking regions and diclofenac in German- and Italian-speaking regions. CONCLUSION In Switzerland, metamizole was increasingly claimed between 2014 and 2019. Metamizole was most frequently claimed by older adults and patients with comedications suggestive of underlying conditions, which can be worsened or caused by use of nonsteroidal anti-inflammatory drugs. The lack of studies regarding the effectiveness and safety of metamizole in this population warrants further investigation.

Abstract
PURPOSE There are only limited data on drug utilization patterns in pediatric inpatients, especially on general wards. The aim of the study was to describe prescribing patterns and their associations with prescribing errors in a university children's hospital in the German-speaking part of Switzerland. METHOD This was a subanalysis of a retrospective single-center observational study. Patient characteristics and drug use of 489 patients with 2693 drug prescriptions were associated with prescribing errors. Drugs were categorized by the Anatomic Therapeutic Chemical Classification System (ATC), patients were categorized by age group according to European Medicines Agency guidelines, and prescribing errors were analyzed by type [Pharmaceutical Care Network Europe (PCNE) classification] and severity of error [adapted National Coordinating Council for Medication Error Reporting (NCC MERP) index]. RESULTS The most frequently prescribed ATC classes were nervous system (N) (42.6%), alimentary system (A) (15.6%), and anti-infective drugs (J) (10.7%). Eighty-two percent of patients were prescribed an analgesic. Most drugs were prescribed for oral (47%) or intravenous (32%) administration, but the rectal route was also frequent (10%). The most frequently prescribed drugs were paracetamol, metamizole, and ibuprofen. The high number of metamizole prescriptions (37% of patients were prescribed metamizole) is typical for German-speaking countries. Older pediatric patients were prescribed more drugs than younger patients. A statistically significant difference was found in the rate of potentially harmful errors across age groups and for gender; children between 2 and 11 years had a higher rate of potentially harmful errors than infants under 2 years (p = 0.029) and female patients had a higher rate of potentially harmful errors than male patients (p = 0.023). Recurring errors were encountered with certain drugs (nalbuphine, cefazolin). CONCLUSIONS Our study provides insight into prescribing patterns on pediatric general wards in a university children's hospital in Switzerland and highlights some areas for future research. Especially, the higher risk for prescribing errors among female pediatric patients needs further investigation.

Abstract
OBJECTIVES To develop a clinical model to predict the risk of an individual patient developing delirium during inpatient rehabilitation, based on patient characteristics and clinical data available on admission. DESIGN Retrospective observational study based on electronic health record data. SETTING AND PARTICIPANTS We studied a previously validated data set of inpatients including incident delirium episodes during rehabilitation. These patients were admitted to ZURZACH Care, Rehaklinik Bad Zurzach, a Swiss inpatient rehabilitation clinic, between January 1, 2015, and December 31, 2018. METHODS We performed logistic regression analysis using backward and forward selection with alpha = 0.01 to remove any noninformative potential predictor. We subsequentially used the Akaike information criterion (AIC) to select the final model among the resulting "intermediate" models. Discrimination of the final prediction model was evaluated using the C-statistic. RESULTS Of the 20 candidate predictor variables, 6 were included in the final prediction model: a linear spline of age with 1 knot at 60 years and a linear spline of the functional independence measure (FIM), a measure of the functional degree of patients independency, with 1 knot at 64 points, diagnosis of disorders of fluid, electrolyte, and acid-base balance (E87), use of other analgesic and antipyretics (N02B), use of anti-parkinson drugs (N04B), and an anticholinergic burden score (ACB) of ≥3 points. CONCLUSIONS AND IMPLICATIONS Our clinical prediction model could, upon validation, identify patients at risk of incident delirium at admission to inpatient rehabilitation, and thus enable targeted prevention strategies.

Abstract
Prescribing errors represent a safety risk for hospitalized patients, especially in pediatrics. Computerized physician order entry (CPOE) might reduce prescribing errors, although its effect has not yet been thoroughly studied on pediatric general wards. This study investigated the impact of a CPOE on prescribing errors in children on general wards at the University Children's Hospital Zurich. We performed medication reviews on a total of 1000 patients before and after the implementation of a CPOE. The CPOE included limited clinical decision support (CDS) such as drug-drug interaction check and checks for duplicates. Prescribing errors, their type according to the PCNE classification, their severity (adapted NCC MERP index), as well as the interrater reliability (Cohen's kappa), were analyzed. Potentially harmful errors were significantly reduced from 18 errors/100 prescriptions (95% CI: 17-20) to 11 errors/100 prescriptions (95% CI: 9-12) after CPOE implementation. A large number of errors with low potential for harm (e.g., "missing information") was reduced after the introduction of the CPOE, and consequently, the overall severity of potential harm increased post-CPOE. Despite general error rate reduction, medication reconciliation problems (PCNE error 8), such as drugs prescribed on paper as well as electronically, significantly increased after the introduction of the CPOE. The most common pediatric prescribing errors, the dosing errors (PCNE errors 3), were not altered on a statistically significant level after the introduction of the CPOE. Interrater reliability showed moderate agreement (Κ = 0.48). Conclusion: Patient safety increased by reducing the rate of prescribing errors after CPOE implementation. The reason for the observed increase in medication reconciliation problems might be the hybrid system with remaining paper prescriptions for special medication. The lacking effect on dosing errors could be explained by the fact that a web application CDS covering dosing recommendations (PEDeDose) was already in use before the implementation of the CPOE. Further investigations should focus on eliminating hybrid systems, interventions to increase the usability of the CPOE, and full integration of CDS tools such as automated dose checks into the CPOE. What is Known: • Prescribing errors, especially dosing errors, are a common safety threat for pediatric inpatients. •The introduction of a CPOE may reduce prescribing errors, though pediatric general wards are poorly studied. What is New: •To our knowledge, this is the first study on prescribing errors in pediatric general wards in Switzerland investigating the impact of a CPOE. •We found that the overall error rate was significantly reduced after the implementation of the CPOE. The severity of potential harm was higher in the post-CPOE period, which implies that low-severity errors were substantially reduced after CPOE implementation. Dosing errors were not reduced, but missing information errors and drug selection errors were reduced. On the other hand, medication reconciliation problems increased.

Abstract
OBJECTIVES To investigate the association between a wide set of baseline characteristics (age, sex, rehabilitation discipline), functional scores [Functional Independence Measure (FIM), cumulative Illness Rating Scale (CIRS)], diseases, and administered drugs and incident delirium in rehabilitation inpatients and, furthermore, to assess clinical implications of developing delirium during rehabilitation. DESIGN Matched case-control study based on electronic health record data. SETTING AND PARTICIPANTS We studied rehabilitation stays of inpatients admitted between January 1, 2015, and December 31, 2018, to ZURZACH Care, Rehaklinik Bad Zurzach, an inpatient rehabilitation clinic in Switzerland. METHODS We conducted unconditional logistic regression analyses to estimate adjusted odds ratios (AORs) with 95% CIs of exposures that were recorded in ≥5 cases and controls. RESULTS Among a total of 10,503 rehabilitation stays, we identified 125 validated cases. Older age, undergoing neurologic rehabilitation, a low FIM, and a high CIRS were associated with an increased risk of incident delirium. Being diagnosed with a bacterial infection (AOR 2.62, 95% CI 1.06-6.49), a disorder of fluid, electrolyte, or acid-base balance (AOR 2.76, 95% CI 1.19-6.38), Parkinson's disease (AOR 5.68, 95% CI 2.54-12.68), and administration of antipsychotic drugs (AOR 8.06, 95% CI 4.26-15.22), antiparkinson drugs (AOR 2.86, 95% CI 1.42-5.77), drugs for constipation (AOR 2.11, 95% CI 1.25-3.58), heparins (AOR 2.04, 95% CI 1.29-3.24), or antidepressant drugs (AOR 1.88, 95% CI 1.14-3.10) during rehabilitation, or an increased anticholinergic burden (ACB ≥ 3) (AOR 2.59, 95% CI 1.41-4.73) were also associated with an increased risk of incident delirium. CONCLUSIONS AND IMPLICATIONS We identified a set of factors associated with an increased risk of incident delirium during inpatient rehabilitation. Our findings contribute to detect patients at risk of delirium during inpatient rehabilitation.

Abstract
BACKGROUND In hospice and palliative care, drug therapy is essential for symptom control. However, drug regimens are complex and prone to drug-related problems. Drug regimens must be simplified to improve quality of life and reduce risks associated with drug-related problems, particularly at end-of-life. To support clinical guidance towards a safe and effective drug therapy in hospice care, it is important to understand prescription trends. OBJECTIVES To explore prescription trends and describe changes to drug regimens in inpatient hospice care. DESIGN We performed a retrospective longitudinal and descriptive analysis of prescriptions for regular and as-needed (PRN) medication at three timepoints in deceased patients of one Swiss hospice. SETTING/SUBJECTS Prescription records of all patients (≥ 18 years) with an inpatient stay of three days and longer (admission and time of death in 2020) were considered eligible for inclusion. RESULTS Prescription records of 58 inpatients (average age 71.7 ± 12.8 [37-95] years) were analyzed. The medication analysis showed that polypharmacy prevalence decreased from 74.1% at admission to 13.8% on the day of death. For regular medication, overall numbers of prescriptions decreased over the patient stay while PRN medication decreased after the first consultation by the attending physician and increased slightly towards death. CONCLUSIONS Prescription records at admission revealed high initial rates of polypharmacy that were reduced steadily until time of death. These findings emphasize the importance of deprescribing at end-of-life and suggest pursuing further research on the contribution of clinical guidance towards optimizing drug therapy and deprescribing in inpatient hospice care.

Abstract
The prevalence of chronic diseases during pregnancy and adverse maternal obstetric outcomes in Switzerland has been insufficiently studied. Data sources, which reliably capture these events, are scarce. We conducted a nationwide observational cross-sectional study (2012−2018) using data from the Swiss Hospital Medical Statistics (MS) dataset. To quantify the recording of chronic diseases and adverse maternal obstetric outcomes during delivery in hospitals or birthing centers (delivery hospitalization), we identified women who delivered a singleton live-born infant. We quantified the prevalence of 23 maternal chronic diseases (ICD-10-GM) and compared results to a nationwide Danish registry study. We further quantified the prevalence of adverse maternal obstetric outcomes (ICD-10-GM/CHOP) during the delivery hospitalization and compared the results to existing literature from Western Europe. We identified 577,220 delivery hospitalizations, of which 4.99% had a record for ≥1 diagnosis of a chronic disease (versus 15.49% in Denmark). Moreover, 13 of 23 chronic diseases seemed to be substantially under-recorded (8 of those were >10-fold more frequent in the Danish study). The prevalence of three of the chronic diseases was similar in the two studies. The prevalence of adverse maternal obstetric outcomes was comparable to other European countries. Our results suggest that chronic diseases are under-recorded during delivery hospitalizations in the MS dataset, which may be due to specific coding guidelines and aspects regarding whether a disease generates billable effort for a hospital. Adverse maternal obstetric outcomes seemed to be more completely captured.

Abstract
BACKGROUND Deterioration of diabetes control can be the first harbinger of pancreatic cancer. However, little is known about how to distinguish patients with pancreatic cancer-related diabetes deterioration from those with type 2 diabetes progression. We aimed to characterize the glycated hemoglobin (HbA1c) and body weight profile of pancreatic cancer patients with deteriorating diabetes before the cancer diagnosis. METHODS Using data from the UK-based Clinical Practice Research Datalink (CPRD) GOLD, we established a study population including pancreatic cancer patients with diabetes deterioration in the >0.5-3 years before the cancer diagnosis and non-cancer patients with deterioration of type 2 diabetes (comparison group). Patients were considered to have diabetes deterioration if their glucose-lowering treatment was intensified. We characterized the longitudinal trajectories of HbA1c and body weight in pancreatic cancer patients compared with non-cancer patients before and after treatment intensification. RESULTS The mean absolute increase in HbA1c from the pre-deterioration period, i.e. the time >1-2 years before treatment intensification, to the time of treatment intensification, was 1.5% ± 1.6% in pancreatic cancer patients vs. 0.9% ± 1.4% in non-cancer patients. After treatment intensification, mean HbA1c remained elevated in pancreatic cancer patients, while it returned to the pre-deterioration level in non-cancer patients. Body weight decreased by 1.9% ± 6.4% in cancer patients and increased by 0.3% ± 5.2% in non-cancer patients between the pre-deterioration period and treatment intensification, on average. CONCLUSIONS Pancreatic cancer-related diabetes deterioration may frequently be characterized by pronounced increases in HbA1c, persistent elevation of HbA1c after treatment intensification, and concomitant weight loss.

Abstract
BACKGROUND Previous studies suggested an elevated risk of venous thromboembolism (VTE) among patients with type 2 diabetes mellitus (T2DM), with a possible sex difference. The impact of glycemic control on the risk of VTE is unclear. Our objective was to analyze the association between glycemic control and the risk of unprovoked (idiopathic) VTE in men and women with T2DM. METHODS We conducted a nested case-control analysis (1:4 matching) within a cohort of patients with incident T2DM between 1995 and 2019 using data from the CPRD GOLD. We excluded patients with known risk factors for VTE prior to onset of DM. Cases were T2DM patients with an unprovoked treated VTE. The exposure of interest was glycemic control measured as HbA1c levels. We conducted conditional logistic regression analyses adjusted for several confounders. RESULTS We identified 2'653 VTE cases and 10'612 controls (53.1% females). We found no association between the HbA1c level and the risk of VTE in our analyses. However, when the most recent HbA1c value was recorded within 90 days before the index date, women with HbA1c levels > 7.0% had a 36-55% increased relative risk of VTE when compared to women with HbA1c > 6.5-7.0%. CONCLUSIONS Our study raises the possibility that female T2DM patients with HbA1c levels > 7% may have a slightly higher risk for unprovoked VTE compared to women with HbA1c levels > 6.5-7.0%. This increase may not be causal and may reflect differences in life style or other characteristics. We observed no effect of glycemic control on the risk of VTE in men.

Abstract
BACKGROUND Evidence on the use of drugs during pregnancy in Switzerland is lacking. OBJECTIVES To evaluate utilisation of prescribed drugs during pregnancy in outpatient care in Switzerland, focusing on treatments for pain, infections, gastro-oesophageal reflux, nausea/vomiting, and constipation. METHODS We conducted a descriptive study using the Swiss Helsana claims database (2014–2018). We established a cohort of pregnancies by identifying deliveries and estimating the date of the last menstrual period. We identified claims for the following drugs during pregnancy; analgesics (opioids, paracetamol, and nonsteroidal anti-inflammatory drugs [NSAIDs]), oral antibiotics, antacids, proton pump inhibitors (PPIs), anti-nausea drugs (propulsives and 5HT3-antagonists), and laxatives. Within these drug groups we quantified exposure prevalence to the most prescribed drugs (to >1% of pregnancies) during pregnancy as well as to specific potentially teratogenic or fetotoxic drugs during specific risk periods. Results were extrapolated relative to the demographic distribution of the Swiss population. RESULTS We identified an extrapolated population of 369,371 pregnancies, with a weighted mean maternal age of 32.0 years (weighted standard deviation 5.1). Analgesics were claimed in 34.5% (95% confidence interval [CI] 33.9–35.0%) of pregnancies, most frequently paracetamol (30.3%, 29.8–30.8%), followed by NSAIDs (8.6%, 8.3–8.8%), and opioids (2.6%, 2.4–2.8%). NSAIDs were claimed in 1.3% (1.2–1.4%) of pregnancies after week 24, and opioids were claimed in 1.3% (1.2–1.4%) in trimester 3. Antibiotics were dispensed in 26.3% (25.8–26.8%) of pregnancies, most frequently amoxicillin (14.6%, 95% CI 14.2–14.9%). Claims for potentially teratogenic or fetotoxic antibiotics during risk periods were each recorded in <0.6% of pregnancies. PPIs were claimed in 16.0% (15.6–16.3%) and antacids in 10.6% (10.3–11.0%) of pregnancies, but several antacid products are not reimbursed and thus not present in insurance claims. Anti-nausea drugs were claimed in 16.4% (16.0–16.7%) of pregnancies, most frequently metoclopramide in 14.4% (14.0–14.7%). Ondansetron was mainly dispensed in trimester 1, 1.0% (0.9–1.1%). In total, 6.4% (6.2–6.7%) of pregnancies had a claim for laxatives, most frequently for macrogol (2.4%, 95% CI 2.2–2.5%). CONCLUSION The observed pattern of claimed drugs during pregnancy is in line with existing treatment guidelines. Exposure to potentially teratogenic and fetotoxic drugs was small, but given the lack of recorded diagnosis, we cannot determine if their use was clinically indicated.

Abstract
BACKGROUND Statins are effective lipid-lowering drugs for the prevention of cardiovascular disease, but muscular adverse events can limit their use. Hydrophilic statins (pravastatin, rosuvastatin) may cause less muscular events than lipophilic statins (e.g. simvastatin, atorvastatin) due to lower passive diffusion into muscle cells. OBJECTIVE To compare the risk of muscular events between statins at comparable lipid-lowering doses and to evaluate if hydrophilic statins are associated with a lower muscular risk than lipophilic statins. DESIGN/SETTING Propensity score-matched cohort study using data from the United Kingdom-based Clinical Practice Research Datalink (CPRD) GOLD. PATIENTS New statin users. Cohort 1: pravastatin 20-40 mg (hydrophilic) vs simvastatin 10-20 mg (lipophilic), cohort 2: rosuvastatin 5-40 mg (hydrophilic) vs atorvastatin 10-80 mg (lipophilic), and cohort 3: simvastatin 40-80 mg vs atorvastatin 10-20 mg. MAIN MEASURES The outcome was a first record of a muscular event (myopathy, myalgia, myositis, rhabdomyolysis) during a maximum follow-up of 1 year. KEY RESULTS The propensity score-matched cohorts consisted of 1) 9,703, 2) 7,032, and 3) 37,743 pairs of statin users. Comparing the risk of muscular events between low-intensity pravastatin vs low-intensity simvastatin yielded a HR of 0.86 (95% CI 0.64-1.16). In the comparison of moderate- to high-intensity rosuvastatin vs equivalent doses of atorvastatin, we observed a HR of 1.17 (95% CI 0.88-1.56). Moderate- to high-intensity simvastatin was associated with a HR of 1.33 (95% CI 1.16-1.53), when compared with atorvastatin at equivalent doses. LIMITATIONS We could not conduct other pairwise comparisons of statins due to small sample size. In the absence of a uniform definition on the comparability of statin doses, the applied dose ratios may not fully match with all literature sources. CONCLUSIONS Our results do not suggest a systematically lower risk of muscular events for hydrophilic statins when compared to lipophilic statins at comparable lipid-lowering doses.

Abstract
OBJECTIVE To analyse utilisation patterns of lipid-lowering drugs and the related costs in Switzerland between the years 2013 and 2019. METHODS We conducted a retrospective descriptive study using administrative claims data of persons aged ≥18 years enrolled with the health insurance company Helsana. To enable statements at the Swiss population level, results were extrapolated according to age, sex and canton of residence. RESULTS The overall prevalence of patients taking lipid-lowering drugs rose from 8.9% (n = 736,174) in 2013 to 11.6% (n = 841,682) in 2019, but varied markedly across regions, with highest values in Ticino and lowest values in Zurich. More than every third individual aged ≥65 years was treated with a lipid-lowering drug in 2019. Statins were by far the most commonly used drugs (>90% of prescriptions), followed by ezetimibe, fibrates and PCSK9 inhibitors. We observed a trend towards the prescription of more potent statins (atorvastatin, rosuvastatin) in recent years. Total costs of lipid-lowering drugs increased from CHF 222 million in 2013 to CHF 230 million in 2019 (+3.5%), whereas annual per capita costs decreased from CHF 302 in 2013 to CHF 273 in 2019 (-9.4%). CONCLUSION The increasing use of lipid-lowering drugs reflects current therapeutic guidelines, but results in high costs for the healthcare system.

Abstract
Introduction: The majority of women with epilepsy require treatment with antiseizure medications (ASM) throughout pregnancy. However, in utero exposure to several ASM has been associated with an increased risk of congenital malformations and/or neurodevelopmental disorders (CM/NDD) in the child, but observational evidence is methodologically heterogeneous.Areas covered: We critically evaluate current evidence on the risk of CM/NDD in children of women with epilepsy after in utero exposure to different ASM. We highlight characteristics of different data sources and discuss their benefits and drawbacks. This review includes evidence published before December 2020.Expert opinion: Given the lack of randomized controlled trials, evidence on in utero safety of ASM originates from methodologically heterogeneous post-marketing observational studies based on registries, prospective cohorts, and large electronic health databases. It has been clearly demonstrated that valproate is associated with a high risk of CM/NDD, whereas lamotrigine and levetiracetam are relatively safe. However, evidence is less explicit for other ASM. Reported risks vary depending on the size and origin of the underlying study population, the definition of exposure and outcomes, and other aspects of the study design. Increased collaboration between data sources to increase sample size is desirable.

OBJECTIVES To assess completeness and validity of bariatric surgery codes in the UK Clinical Practice Research Datalink (CPRD) GOLD compared with Hospital Episodes Statistics (HES). METHODS We conducted a validation study among patients in the UK-based CPRD GOLD with linkage to HES (1998 to 2017). Since the same surgery codes are used for bariatric and other gastrointestinal surgery we assessed code distribution patterns used in patients with bariatric versus other gastrointestinal surgery by presence of other conditions such as obesity and gastrointestinal cancer. We developed algorithms to identify bariatric surgery and calculated validity measures (ie, positive/negative predictive value [PPV/NPV], sensitivity, and specificity) of each in CPRD GOLD compared with HES (gold standard). RESULTS Among 7 357 007 available patients we identified 10 190 patients who had a total of 14 046 potential bariatric surgery codes in CPRD GOLD and/or HES. Surgery code patterns differed between bariatric surgery and assumed other gastrointestinal surgery. The sensitivity of CPRD GOLD bariatric surgery coding improved from an overall of 56% to 69-71% when applying stricter algorithms (ie, in obese patients or obese, gastrointestinal disease/complication free patients) but PPVs remained at 53%-55%. NPVs and specificities of CPRD GOLD bariatric surgery coding achieved ≥99.8% for all algorithms. CONCLUSION Our results suggest that using CPRD GOLD and HES data and a wide selection of surgery codes will result in the most complete and accurate capture of bariatric surgery events. Validity measures of CPRD GOLD bariatric surgery codes were identical in obese patients and more restrictive populations.

Abstract
CONTEXT Patients with type 2 diabetes mellitus (T2DM) have an increased risk of low-trauma fractures. However, the effect of antidiabetic medication in relation to glycemic control on the risk of fracture is poorly understood. OBJECTIVE This work aimed to evaluate the association between the level of glycemic control, use of antidiabetic medication, and risk of low-trauma fractures in patients with newly diagnosed T2DM. METHODS We conducted a nested case-control analysis among individuals registered in the Clinical Practice Research Datalink. The base population consisted of patients with newly diagnosed T2DM from 1995 to 2017. Cases were patients with a low-trauma fracture after T2DM diagnosis. We matched 4 controls to each case. Exposures of interest were glycemic control (last glycated hemoglobin [HbA1c] level before fracture) and type of diabetes treatment. We conducted conditional logistic regression analyses adjusted for several confounders. RESULTS We identified 8809 cases and 35 219 controls. Patients with current metformin use and HbA1c levels of less than 7.0% and between 7.0-8.0% had a reduced risk of fractures (adjusted odds ratio 0.89; 95% CI, 0.83-0.96 and 0.81; 95% CI, 0.73-0.90, respectively) compared with untreated patients. However, in patients receiving metformin plus 1 or 2 other antidiabetic drugs, or insulin (alone or in addition to other antidiabetic medication), the level of glycemic control was not associated with the risk of fracture compared with untreated patients. CONCLUSIONS While patients with good or medium glycemic control receiving current metformin monotherapy had a lower risk of fracture compared with untreated patients, glycemic control in patients receiving treatment other than metformin was not associated with risk of fracture.

Abstract
AIMS To determine whether enzyme-inducing antiseizure drugs (ASDs) affect the risk of developing chronic obstructive pulmonary disease (COPD) or lung cancer in smokers. METHODS Cases of COPD and lung cancer and matched controls without these conditions were identified from a population of smokers with ≥1 prescription for any type of ASD in the Clinical Practice Research Datalink UK database of patients managed in primary care (1995-2016). A matched case-control study was performed utilising multivariate logistic regression analyses of exposure to enzyme-inducing ASDs compared to non-enzyme-inducing ASDs. The duration of ASD exposure and level of tobacco exposure were also assessed. RESULTS We identified 5952 incident COPD and 1373 incident lung cancer cases, and 59 328 and 13 681 matched controls, respectively. Compared with never use, ever use of enzyme-inducing ASDs was associated with slightly decreased risk estimates of COPD (adjusted odds ratio: 0.85, 95% confidence interval: 0.81-0.89) and lung cancer (adjusted odds ratio: 0.82, 95% confidence interval: 0.73-0.92). These risk estimates were attenuated in heavy smokers. CONCLUSION We found slightly decreased risk estimates of COPD and lung cancer among smokers taking enzyme-inducing ASDs and hypothesise that this may be related to induction of detoxification of tobacco-specific lung toxins.

Abstract
PURPOSE Three previous studies reported controversial results regarding selective serotonin reuptake inhibitor (SSRI) exposure and cataract development. We therefore aimed to assess risk of cataract associated with previous exposure to SSRI using data from a large health insurance in Switzerland. METHODS In a case-control study, we analyzed individuals insured by the Helsana Group, a large Swiss health insurance provider. We matched patients aged 40 years or older with cataract extraction (i.e., a proxy for a cataract diagnosis) in 2014 or 2015 to four control patients, on age, sex, date of cataract extraction, and area of residence. Exposure of interest was the number of SSRI claims prior to cataract extraction. We conducted conditional logistic regression analyses to calculate odds ratios (OR) with 95% confidence intervals (CI). We adjusted our analyses for the presence of hypertension, diabetes, glaucoma, systemic steroid use, and use of other antidepressant drugs. RESULTS We identified 13,773 cataract cases and 51,625 matched controls. Compared with non-use, long-term use of SSRI (≥ 20 claims) was not associated with an altered risk of cataract (adjusted OR 0.93, 95% CI 0.84-1.04). The analysis of the individual drug substances also yielded no statistically significant association between drug exposure and the risk of cataract. CONCLUSIONS According to our study, use of SSRI does not change the risk of cataract in the overall population.

Abstract
OBJECTIVE Using the UK Clinical Practice Research Datalink, we examined the incidence of glucocorticoid (GC)-related serious adverse events (SAEs) in rheumatoid arthritis (RA) and non-RA patients and quantified the risk of SAEs in patients with RA. METHODS We matched incident patients with RA to an age- and sex-matched, non-RA comparison group of equal size. In a cohort analysis, we estimated incidence rates (IRs) and IR ratios (IRRs) for GC-related AEs (i.e., diabetes mellitus [DM], osteoporosis, fractures, glaucoma, hypertension, gastrointestinal [GI] perforation or bleeding, thrombotic stroke or myocardial infarction [MI], or death), stratified by GC use. We conducted a series of nested case-control analyses among patients with RA, evaluating the effects of increasing cumulative and average daily GC dose. Cases of each outcome were matched to controls for age, sex, and general practice. We calculated adjusted odds ratios (ORs) with 95% confidence intervals (95% CIs) for each outcome. RESULTS Patients with RA had a higher incidence for all investigated SAEs except glaucoma, compared to non-RA patients. IRRs were greater in those patients prescribed a GC than in those without. In patients with RA, GCs were associated with an elevated risk of DM (adjusted OR 1.33 [95% CI 1.14-1.56]), osteoporosis (adjusted OR 1.41 [95% CI 1.25-1.59]), thrombotic stroke or MI (adjusted OR 1.28 [95% CI 1.07-1.52]), serious infection (adjusted OR 1.28 [95% CI 1.11-1.48]), and death (adjusted OR 1.33 [95% CI 1.19-1.48]). There was a trend of increasing risk with increasing cumulative and average daily GC dose for all outcomes other than glaucoma, hypertension, and GI perforations or bleeding (P < 0.05). CONCLUSION Patients with RA had an increased incidence of GC-related AEs. Increasing cumulative and average daily GC doses were found to be associated with an increasing risk of developing an AE.

Abstract
BACKGROUND Low vaccination coverage as well as incomplete and delayed vaccinations pose a risk for the individual and population protection from vaccine-preventable diseases. AIM To describe vaccination patterns for nationally recommended basic and supplementary vaccinations in Swiss preschool children. METHODS We performed a descriptive study based on administrative claims data from a large Swiss health insurer (Helsana), in cohorts of children born between January 2010 and December 2016. We assessed coverage rates of nationally recommended basic vaccinations (i.e., diphtheria, tetanus, acellular pertussis [DTaP], Haemophilus influenzae type b [Hib], poliomyelitis [IPV], measles, mumps, and rubella [MMR]) and supplementary vaccinations (i.e., pneumococcal conjugate vaccine [PCV] and meningococcal group C conjugate vaccine [MCV]) for each birth cohort at the age of 13, 25, and 37 months. Additionally, we analysed timeliness of vaccinations using inverse Kaplan-Meier curves. Results were extrapolated to the Swiss population. RESULTS The study population comprised 563,216 children. We observed continuously increasing coverage rates for all vaccinations until the 2015 birth cohort. Overall, up-to-date status for the first dose of studied vaccinations at 37 months was as follows: DTaP: 95.4%; Hib: 94.9%; IPV: 95.5%; MMR: 86.8%; PCV: 83.2%; and MCV: 66.7%. On average, however, only seven out of ten children had an up-to-date status for completed basic vaccinations; even less (six out of ten) were up-to-date for recommended supplementary vaccinations at 37 months of age. Moreover, 4% of all analysed children received none of the recommended vaccinations and there were substantial regional differences. Delays in vaccine administration were common. The most frequently postponed basic vaccination was MMR; 22.6% of children vaccinated with the first dose experienced delays relative to age-appropriate standards. CONCLUSION To avoid future outbreaks and transmission of vaccine-preventable diseases, vaccination coverage in Switzerland must be further improved. In addition, more emphasis should be placed on timely vaccination.

Abstract
OBJECTIVE To estimate the risk of hand osteoarthritis (HOA) associated with hormone replacement therapy (HRT). METHODS We conducted a nested case-control study using data from the UKbased Clinical Practice Research Datalink (1998-2017). In the study inception cohort comprised women at age 45. We matched women with incident HOA during follow-up (cases) to osteoarthritisfree controls on age and calendar date (index date, ID), in a ratio of 1:4. We applied conditional logistic regression to calculate odds ratios (OR) with 95 % confidence intervals (CI) of HOA associated with new HRT use compared with non-use overall, and for women with recorded menopause we calculated separate ORs according to the time between menopause and HRT initiation (current users), and the time between HRT cessation and the ID (past users), versus non-users. RESULTS There were 3440 cases and 13,760 controls (mean age: 50.9 ± 4.1 years). We observed an adjusted OR (aOR) of HOA of 1.32 (95 % CI 1.17-1.48) in HRT users (versus nonusers), which attenuated to 0.98 (95 % CI 0.85-1.14) in women with recorded menopause. Current users (versus nonusers) who initiated HRT 3 months before or after menopause had an aOR of 0.72 (95 % CI 0.55-0.96), while aORs increased with later HRT initiation. Among past users (versus non-users), we observed an aOR of 1.25 (95 % CI 0.86-1.81) when HRT use was stopped ≤18 months before the ID, approaching the null with increasing duration between HRT cessation and the ID. CONCLUSION Current HRT use was associated with a decreased risk of HOA if initiated around menopause, but the risk reduction disappeared after HRT cessation.

Abstract
Reports of metamizole-induced neutropenia have increased in Switzerland and Germany over the last decades, most likely reflecting increased use of metamizole. To date, there are no effective strategies to identify patients at increased risk of metamizole-induced neutropenia. In this observational, multi-center comparative study, characteristics of patients with metamizole-associated neutropenia were compared with patients treated with metamizole without developing adverse hematological reactions. Patients with metamizole-induced neutropenia treated at the University Hospitals Basel and Bern between 2005 and 2017 were included. Tolerant comparison patients with continuous metamizole treatment (≥500 mg/day for at least 28 days) were recruited from GP offices and community pharmacies. Forty-eight patients with metamizole-induced neutropenia, consisting of 23 and 25 cases with inpatient-acquired and outpatient-acquired neutropenia, respectively, were compared to 39 metamizole tolerant comparison patients. Median latency until first diagnosis of neutropenia was 6 days (1-61 days) in inpatient cases and 19 days (2-204 days) in outpatient cases. There was no association between non-myelotoxic and non-immunosuppressive co-medication (p = .6627), history of drug allergy (p = .1304), and preexisting auto-immune diseases (p = .2313) and the development of metamizole-induced neutropenia. Our results suggest that autoimmune diseases, history of drug allergy, and concomitant treatment with non-myelotoxic and non-immunosuppressive drugs are likely not individual risk factors for metamizole-associated neutropenia.

Abstract
BACKGROUND To date, comprehensive data on drug utilisation in Swiss nursing homes are lacking. OBJECTIVE To describe drug prescription patterns, polypharmacy and potentially inappropriate medication (PIM) in Swiss nursing home residents (NHR). METHODS Using administrative claims data provided by the Swiss health insurance company Helsana, we assessed drug claims and drug costs in 2016 in individuals aged ≥65 years and insured with Helsana, who were either NHR or living in the community (reference group, RG). In particular, we analysed the prevalence of polypharmacy (≥5 claims for different drugs during a 3-month period) and PIM use according to the 2015 Beers criteria and the PRISCUS list. We standardised the results to the Swiss population. RESULTS In 2016, NHR had on average nearly twice as many drug claims per capita as individuals in the RG (NHR 58.8; RG 30.8). The average per capita drug costs per day for NHR were low, but higher than in the RG (NHR CHF 8.55; RG CHF 5.45). The same pattern applied to the prevalence of polypharmacy (NHR 85.5%; RG 50.4%). Standardisation by age and sex did not materially alter these observations. Overall, 79.1% of NHR received ≥1 PIM, and 56.2% were long-term users (≥3 claims) of at least one PIM (based on the combined PRISCUS list and Beers criteria). Among all PIMs in nursing homes, quetiapine (antipsychotic agent), lorazepam (anxiolytic agent) and zolpidem (hypnotic agent) were the most prevalent (22.4, 20.2 and 13.0%, respectively). CONCLUSIONS The high prevalence of polypharmacy and PIM in Swiss nursing homes may indicate a need for interventions aiming at de-prescribing drugs with an unfavourable benefit-risk profile.

Abstract
Purpose Subjective tinnitus is a common symptom with potentially negative impact on quality of life. More research is required to gain a deeper understanding of the disease and its clinical presentation. To estimate the incidence of tinnitus and to describe patient-related characteristics such as lifestyle factors and comorbidities. Patients and methods Using the Clinical Practice Research Datalink, we calculated incidence rates of first-time diagnosed tinnitus in an adult population between 2000 and 2016. We stratified incidence rates by sex, age, and year of diagnosis. Additionally, we performed a 1:1 matched case-control study comparing body mass index, lifestyle factors and selected comorbidities between patients with incident tinnitus and tinnitus-free controls. Results We identified 109 783 adults with a first-time diagnosis of tinnitus between 2000 and 2016, yielding an overall age-standardized incidence rate of 25.0 new tinnitus cases per 10,000 person-years (95% CI: 24.6–25.5). There was a steady increase in tinnitus incidence throughout the study period. Approximately 80% of tinnitus cases were diagnosed at age 40 years or older. We observed the highest incidence rate in individuals aged 60–69 years (41.2 per 10,000 person-years, 95% CI: 40.7–41.7). Smokers and alcohol drinkers were at lower risk of being diagnosed with tinnitus compared with non-smokers and non-drinkers, respectively. The occurrence of tinnitus was strongly associated with a recent diagnosis of several otological and vestibular disorders as well as head and neck disorders. Conclusion The present observational study found an increasing incidence of tinnitus over time, emphasizing the continuously growing health burden. The findings on patient characteristics, lifestyle factors, and selected comorbidities contribute to a better understanding of risk factors for tinnitus.

Abstract
WHAT IS KNOWN AND OBJECTIVE The evaluation of clinical pharmacy services is essential for their further development and establishment. We analysed drug-related problems (DRPs) and subsequent clinical pharmacists' interventions (PIs) at a Swiss university hospital. METHOD We conducted a retrospective analysis of DRPs and subsequent PIs that were identified and implemented during interdisciplinary ward rounds in internal medicine at the University Hospital Basel, Switzerland, between 2015 and 2017. We estimated the potential clinical and economic impact of PIs using a validated evaluation tool (CLEOde ). RESULTS AND DISCUSSION Based on medication reviews of 5441 patients, clinical pharmacists identified 5024 DRPs, of which 2892 DRPs (57.6%) were followed by a PI that was directly accepted and implemented by the physician in charge and included in the present analysis. The leading cause and type of PIs were inappropriate dose and dose adjustment, respectively. Overall, 97.8% of DRPs were followed by PIs with an expected clinical benefit for the patients (major: 11.1%; moderate: 27.6%; minor: 59.1%). The drugs most often involved in PIs of major clinical impact were antithrombotics, acid blockers and cardiovascular drugs. With regard to the economic impact, 40.7% of DRPs implied PIs resulting in an increase of immediate therapy costs, whereas 39.3% implied PIs resulting in a decrease of immediate therapy costs. The remaining PIs were cost-neutral. WHAT IS NEW AND CONCLUSION This study emphasizes that clinical pharmacists may help improve the effectiveness and safety of pharmacotherapy on acute care medical wards.

Abstract
OBJECTIVES To evaluate the potential of blood glucose levels and weight change before the onset of diabetes as predictors of pancreatic cancer among subjects with new-onset diabetes, that is, cancer-related diabetes versus normal type 2 diabetes. METHODS We conducted a case-control study among subjects with new diabetes in the United Kingdom-based Clinical Practice Research Datalink. Cases were pancreatic cancer subjects with diabetes for ≤2 years before the cancer diagnosis (i.e., cancer-related diabetes). Controls were cancer-free, type 2 diabetic subjects matched to cases on age, sex, and diabetes duration. We calculated adjusted odds ratios (aORs) for pancreatic cancer as a function of both weight change and blood glucose before the onset of diabetes. RESULTS Weight loss of 10.0%-14.9% at diabetes onset was associated with an aOR for pancreatic cancer of 3.58 (95% CI 2.31-5.54), loss of ≥15.0%, with an aOR of 4.56 (95% CI 2.82-7.36), compared with stable weight. Blood glucose levels of ≤5.1 mmol/L or 5.2-5.6 mmol/L before diabetes onset were associated with an increased risk of a pancreatic cancer diagnosis, with aORs of 2.42 (95% CI 1.60-3.66) and 2.20 (95% CI 1.45-3.35), respectively, when compared with blood glucose levels ≥6.3 mmol/L within >2-3 years before cancer detection. CONCLUSIONS Weight loss as well as blood glucose levels in the normal range (and thus rapid development of hyperglycemia) before diabetes onset may be predictive of pancreatic cancer-related diabetes and may help target which subjects with new diabetes to refer for pancreatic cancer screening examinations.

Abstract
CONTEXT Diabetes mellitus (DM) has been associated with an increased risk of fractures. However, the effect of glycemic control on the risk of fracture is not well understood. OBJECTIVE To evaluate the association between glycemic control and the risk of low-trauma fractures in patients with type 1 DM (T1DM) and type 2 DM (T2DM). DESIGN Nested case-control analysis. SETTING UK-based Clinical Practice Research Datalink. PATIENTS OR OTHER PARTICIPANTS The study population was patients whose T1DM or T2DM had been newly diagnosed between 1995 and 2015. The cases were patients with a low-trauma fracture after DM onset. We matched four controls to each case by age, sex, general practice, fracture date, and DM type and duration. STATISTICAL ANALYSIS Conditional logistic regression analyses were performed, adjusted for covariates, including body mass index, smoking, DM complications and medications. RESULTS The study population included 3329 patients with T1DM and 44,275 patients with T2DM. The median duration between DM onset and fracture date was 4.5 years for both T1DM and T2DM. The risk of fracture was increased in the patients with T1DM with a mean hemoglobin A1c >8.0% (adjusted OR, 1.39; 95% CI, 1.06 to 1.83) compared with those patients with T1DM and a mean hemoglobin A1c ≤7.0%. No such effect was found in the patients with T2DM. Independently of glycemic control, the risk of fracture was elevated in patients with T2DM and the current use of rosiglitazone and pioglitazone. CONCLUSIONS The effect of glycemic control on the risk of low-trauma fracture differs between patients with T1DM and T2DM. Poor glycemic control increased the risk of fractures in patients with T1DM but not in those with T2DM.

Abstract
BACKGROUND/AIM Use of ACE inhibitors (ACEIs) has been associated with an increased risk of cataract in a previous observational study in humans. In contrast, ACEIs were associated with beneficial effects on cataract development in experimental studies. We assessed the risk of cataract in relation to exposure to ACEI and other antihypertensive drugs. METHODS This is a case-control study based on data from the UK-based Clinical Practice Research Datalink (CPRD). We included first-time cataract patients aged ≥40 years between 1995 and 2015 and an equal number of cataract-free controls. We matched the controls to cases on age, sex, general practice, date of first cataract (ie, index date) and years of history in the CPRD prior to the index date. We assessed the number of prescriptions for ACEI and other antihypertensive drugs in detail and explored the use of single ACEI substances. We performed conditional logistic regression and conducted various sensitivity analyses to test the robustness of our findings. We calculated the risk of cataract associated with previous exposure to ACEI, measured as OR with 95% CIs, and adjusted the multivariable model for body mass index, smoking, diabetes, hypertension, prescriptions of systemic corticosteroids and other antihypertensive drugs. RESULTS We identified 206 931 cataract cases and the same number of matched controls. Use of ACEI was not associated with a materially altered risk of cataract compared with non-use of ACEI, neither in the main analysis (OR 1.06, 95% CI 1.04 to 1.08) nor in any of the sensitivity or stratified analyses. CONCLUSION In our large observational study, use of ACEI was not associated with an altered risk of cataract.

Abstract
OBJECTIVE To investigate the association between statin therapy initiation and incident hand osteoarthritis (OA). METHODS We performed a propensity score-matched cohort study using data from the UK-based Clinical Practice Research Datalink. Statin initiators had ≥1 statin prescription between 1996 and 2015 and were matched 1:1 on their propensity score to noninitiators within 10 sequential 2-year cohort entry blocks. After a 180-day run-in period, patients were followed in an as-treated approach until a recorded diagnosis of hand OA or until censoring (change in exposure status, development of an exclusion criterion, or maximum follow-up of 5.5 years). We applied Cox proportional hazard regression to calculate hazard ratios (HRs) with 95% confidence intervals (95% CIs) overall and in subgroups of sex, age, statin dose, statin agent, preexisting dyslipidemia, and treatment duration. To compare results, we ran all analyses with negative and positive control outcomes and assessed generalized OA as a secondary outcome. We further performed the overall analysis with an active comparator (topical glaucoma therapy initiators). RESULTS Among 233,608 statin initiators and the same number of noninitiators, we observed an overall HR for hand OA of 0.98 (95% CI 0.88-1.09). The observed null result remained unchanged in all subgroups. Results were highly similar for generalized OA and negative control outcomes. In addition, the active comparator analysis showed a null result with an HR for hand OA of 0.85 (95% CI 0.56-1.29). Previously known associations with positive control outcomes were observed. CONCLUSION There was no association between statin initiation and incident hand OA in this study.

Abstract
High-grade glioma (HGG) is associated with poor prognosis. Drug repurposing evolves as new modality to improve standard therapy. The antidiabetic drug metformin has been found to inhibit glioma cell growth in vitro and in vivo. The aim of the present retrospective cohort study was to evaluate the survival of patients with HGG with or without treatment with metformin, based on a large cohort of a cancer registry. The analysis included 1,093 patients with HGG diagnosed between 1998 and 2013 from the population-based clinical cancer registry Regensburg (Germany), which covers 2.1 Mio inhabitants and 98% of all cancer diagnoses. We performed multivariable adjusted Cox-regression analyses. Hazard Ratios (HRs) with 95% Confidence Intervals (CIs) for overall survival (OS) and progression-free survival (PFS) of patients with HGG with or without treatment with metformin were obtained. Use of metformin was associated with a significantly better overall and progression-free survival of patients with WHO grade III glioma (HR for OS = 0.30; 95% CI = 0.11-0.81, HR for PFS = 0.29; 95% CI = 0.11-0.78), while there were no significant relations with OS (HR = 0.83; 95% CI = 0.57-1.20) or PFS (HR = 0.85; 95% CI = 0.59-1.22) in patients with WHO grade IV glioma. In conclusion, use of metformin is associated with better overall and progression-free survival of patients with WHO grade III. Possible underlying mechanisms include the higher prevalence of IDH mutations in WHO grade III glioma, which might sensitize to the metabolic drug metformin.

Abstract
Background The shift from inpatient to ambulatory care has resulted in an increase in home care patients. Little is known regarding medication safety associated with patient transfer from hospital to home care. Objective To evaluate medication-related problems in patients transferring from hospital to home care in Switzerland. Setting A non-for-profit home care organization in the city of Lucerne/Switzerland. Methods We conducted a prospective observational study, including patients aged ≥ 64 years and receiving ≥ 4 medications at hospital discharge. Two structured questionnaires assessing the transfer process were completed by home care nurses. Prescription quality was assessed using a PCNE Type 2b Medication Review. Main outcome measures The quality of the transfer process was measured comparing agreed-upon with reported parameters. Prescription quality was analyzed assessing the unambiguity of the prescription. Potentially inappropriate medications (Priscus® list), contraindications, duplications and interactions, and clinical pharmacist-identified potential medication-related problems were collected. Results Study patients (n = 100) received 8.6 ± 3.5 regularly administered medications. Only 5/100 patients had a complete set of written discharge information. At the time of the first visit, 13/100 patients had no written medication information available. Discharge medication prescriptions were clear to nurses in 62% of patients. In 20 patients, the required medications were unavailable, resulting in 19 medication errors. Assessment by a clinical pharmacist revealed only 33/100 patients had a clear discharge prescription. Of a total of 984 prescribed drugs, 16% were considered to be ambiguous, 22 (2.2%) were potentially inappropriate. 7/984 drugs were contraindicated, 8 were duplicates. Conclusion In addition to the known risk factors in patients transferring from hospital to home care (age, polymedication, multiple providers), 3 major problems impacted upon medication safety: fragmented communication, unreliable medication availability and a poor prescription quality. Clinical pharmacists are an important option to improve medication safety ass.

Abstract
CONTEXT Exogenous testosterone administration may affect blood clotting, polycythaemia, and may increase atherosclerosis, though any association with cardiovascular events is unclear. While the literature is inconclusive, some studies have suggested testosterone use may increase short-term risk of cardiovascular events and stroke, and injection testosterone may convey higher risks than other dosage forms. OBJECTIVE We sought to evaluate the short-term cardiovascular risk of receiving injection testosterone. DESIGN We conducted a case-crossover analysis comparing injection testosterone exposure in the 7 days prior to an outcome event to referent windows in the past to estimate the acute association of cardiovascular outcomes with the receipt of testosterone injections. PATIENTS We identified adult male testosterone users hospitalized with myocardial infarction (MI), stroke or a composite of MI, stroke or unstable angina in US commercial claims (2000-2013) or Medicare (2007-2010) databases. MEASUREMENTS We identified testosterone use for the patients from pharmacy dispensing claims or in-office procedure codes in the insurance billing data. RESULTS We identified 2898 commercially insured men with events and recent testosterone use, and 339 from Medicare. Injected testosterone was associated with an increased risk of adverse events (composite outcome of myocardial infarction, stroke or unstable angina) in the immediate postinjection period for the older, Medicare population only: commercial insurance, odds ratios (OR) = 0.98 (95% confidence intervals [CI]: 0.86-1.12); Medicare, OR = 1.45 (1.07, 1.98). This association was either greatly attenuated or not present when evaluating receipt of any testosterone dosage forms (injection, gel, patch, implant): commercial insurance, OR = 1.01 (0.92, 1.11); Medicare, OR = 1.26 (95% CI: 0.98-1.63). CONCLUSIONS Testosterone injections were uniquely associated with short-term risk of acute cardio- and cerebrovascular events in older adult men following injection receipt.

Abstract
Background To evaluate the adverse events profile of oral prednisolone among adult asthma patients in the UK. Methods Using data from the UK-based Clinical Practice Research Datalink, we conducted a series of cohort studies to quantify incidence rates and incidence rate ratios, and a series of nested case-control analyses to estimate crude and adjusted odds ratios, of 11 different potential corticosteroid-related adverse events (bone-related conditions, hypertension, peptic ulcer, severe infections, herpes zoster, diabetes mellitus type 2, cataract, glaucoma, chronic kidney disease, affective disorders, and cardiovascular events). Results Between 165,900 and 269,368 asthma patients were included in each of the 11 cohorts, of whom between 836 and 16,192 developed an outcome of interest. Incidence rates per 1000 person-years of potential corticosteroid-related adverse events in patients with new current use of oral prednisolone ranged from 1.4 (95% confidence interval [CI], 1.0–1.8) for peptic ulcer to 78.0 (95% CI, 74.8–81.2) for severe infections. After adjusting for confounding, current oral prednisolone use was most strongly associated with an increased risk of severe infection, compared with non-use of prednisolone; OR 2.16 (95% CI, 2.05–2.27). There were smaller elevated risks of peptic ulcer, affective disorders, and cataract at higher doses, and marginally increased risks of herpes zoster, cardiovascular events, diabetes mellitus type 2, and bone related conditions, compared with non-use of prednisolone. We did not observe an association between oral prednisolone use and glaucoma, chronic kidney disease, or hypertension. Conclusion Oral prednisolone use is associated with infections, gastrointestinal, neuropsychiatric, ocular, cardiovascular, metabolic, and bone-related complications among adult asthma patients.

Abstract
BACKGROUND Meningioma is a frequent primary intracranial tumor, the etiology of which is potentially related to adiposity. Metabolic syndrome (MetS) is an increasingly common disease characterized by having at least three of the following conditions: central adiposity, arterial hypertension, dyslipidemia, and insulin resistance. Only one prior study investigated MetS in relation to meningioma risk and found a positive association between the two. RESULTS Among 2,027 cases and 20,269 controls, body mass index was positively associated with meningioma (p-value for trend < 0.0001). Arterial hypertension was also associated with an increased risk of meningioma (OR = 1.34; 95% CI = 1.20- 1.49). By comparison, high-density lipoprotein, triglycerides, fasting serum glucose, and use of ACE-inhibitors, AT-II inhibitors, beta-blockers, diuretics, calcium antagonists, nitrates, or statins were not associated with risk of meningioma. MATERIALS AND METHODS We conducted a matched case-control analysis using data from the U.K.-based Clinical Practice Research Datalink (CPRD) to analyse medical conditions and treatments related to MetS in cases with meningioma and meningioma-free controls. We identified all cases with an incident diagnosis of meningioma between 1995 and 2015 and matched each to ten controls on age, sex, calendar time, general practice, and number of years of active history in the CPRD prior to the index date. Exposures were assessed using computerised records. We conducted conditional logistic regression analysis to determine relative risks, estimated as odds ratios (ORs) with 95% confidence intervals (CIs), adjusted for confounding factors. CONCLUSIONS Obesity and arterial hypertension are positively associated with risk of meningioma. Further studies are needed to better understand potential underlying biologic mechanisms.

Abstract
INTRODUCTION Case reports and pharmacovigilance data reported cases of tendon ruptures in statin users, but evidence from observational studies is scarce and inconclusive. We aimed to assess the association between new statin use and tendon rupture. METHODS We performed a propensity score (PS)-matched sequential cohort study, using data from the Clinical Practice Research Datalink. Patients aged ≥45 years with at least one new statin prescription between 1995 and 2014 were PS-matched within 2-year entry blocks to patients without a statin prescription during the block. We followed patients until they had a recorded Achilles or biceps tendon rupture, completed 5 years of follow-up, or were censored for change in exposure status or another censoring criterion. We calculated hazard ratios (HRs) with 95 % confidence intervals (CIs), applying Cox proportional hazard analyses in the overall cohort (crude and multivariable) and in the PS-matched cohort. We performed subgroup analyses by sex, age, treatment duration, and statin dose. RESULTS We observed a crude HR of 1.32 (95 % CI 1.21-1.44) in the overall cohort, which attenuated after multivariable adjustment (HR 1.02, 95 % CI 0.92-1.12) and after PS-matching (HR 0.95, 95 % CI 0.84-1.08). Crude HRs were higher in women than in men, but remained around null in both sexes after multivariable adjustment and PS-matching. Subgroup analyses by age, treatment duration, and statin dose revealed null results across all subgroups. CONCLUSION The results of this cohort study suggest that statin use does not increase the risk of tendon rupture, irrespective of gender, age, statin dose, or treatment duration.

Abstract
BACKGROUND AND OBJECTIVE Ménière's disease (MD) is a disorder of the inner ear typically showing recurrent acute episodes of vertigo, hearing loss, and tinnitus. Epidemiologic studies on MD are scarce. We assessed the incidence rates (IRs) of MD and describe the characteristics of MD cases, comparing them to control patients without recorded evidence of MD. STUDY DESIGN We conducted a retrospective population-based follow-up study and a nested case-control analysis using data from the UK-based Clinical Practice Research Datalink. METHODS We identified patients between 18 and 79 years of age with an incident MD diagnosis between January 1993 and December 2014. We assessed the IRs of betahistine-treated MD. In the nested case-control analysis, we matched 4 controls to each MD case on sex, age, general practice, years of active history in the database, and calendar time. We conducted a χ2 test to present p values in order to compare the prevalence of demographics, comorbidities, and co-medication between cases and controls. RESULTS We identified 5,508 MD cases and 22,032 MD-free controls (65.4% females). The overall IR for MD in the UK was 13.1 per 100,000 person-years. More cases were female, and the mean age at diagnosis was 55.4 ± 13.7 years. Smoking and alcohol consumption were less prevalent among MD cases. Depression, other affective disorders, sleeping disorders, anxiety, and migraine were more prevalent among MD cases than among controls. CONCLUSIONS MD is uncommon in primary care in the UK with a preponderance among females.

Abstract
BACKGROUND Metformin is a commonly used oral antidiabetic agent that has been associated with decreased cancer risk. However, data regarding the association between metformin use and the risk of meningioma are unavailable. METHODS We conducted a matched case-control analysis using data from the U.K.-based Clinical Practice Research Datalink (CPRD) to analyse diabetes status, duration of diabetes, glycemic control, and use of metformin, sulfonylureas, and insulin in relation to the risk of meningioma. We conducted conditional logistic regression analyses to determine relative risks, estimated as odds ratios (ORs) with 95% confidence intervals (CIs) and adjusted for body mass index, smoking, history of arterial hypertension, myocardial infarction, and use of estrogens (among women). RESULTS We identified 2,027 meningioma cases and 20,269 controls. For diabetes there was the suggestion of an inverse association with meningioma (OR = 0.89; 95%CI = 0.74-1.07), which was driven by an inverse relation among women (OR = 0.78; 95%CI = 0.62-0.98), in whom we also noted a suggestive inverse association with duration of diabetes (p-value for trend = 0.071). For metformin there was a suggestive positive relation, particularly after matching on duration of diabetes and HbA1c level (OR = 1.64; 95%CI = 0.89-3.04). Sulfonylureas showed no clear association (OR = 0.91; 95%CI = 0.46-1.80). For insulin there was the suggestion of an inverse relation, in particular when comparing a high vs. low number of prescriptions (OR = 0.58; 95%CI = 0.18-1.83). CONCLUSION Further studies are needed to solidify a possible inverse association between diabetes and meningioma risk and to clarify the role of antidiabetics in this context.

Abstract
AIM The aim was to evaluate the impact of staff training and wearing safety vests as a combined intervention on interruptions during medication preparation and double-checking. BACKGROUND Interruptions and errors during the medication process are common and an important issue for patient safety in the hospital setting. METHODS We performed a pre- and post-intervention pilot-study using direct structured observation of 26 nurses preparing and double-checking 431 medication doses (225 pre-intervention and 206 post-intervention) for 36 patients (21 pre-intervention and 15 post-intervention). RESULTS With staff training and the introduction of safety vests, the interruption rate during medication preparation was reduced from 36.8 to 28.3 interruptions per hour and during double-checking from 27.5 to 15 interruptions per hour. CONCLUSION This pilot-study showed that the frequency of interruptions decreased during the critical tasks of medication preparation and double-checking after the introduction of staff training and wearing safety vests as part of a quality improvement process. IMPLICATIONS FOR NURSING MANAGEMENT Nursing management should acknowledge interruptions as an important factor potentially influencing medication safety. Unnecessary interruptions can be successfully reduced by considering human and system factors and increasing both staff and nursing managers' awareness of 'interruptive communication practices' and implementing physical barriers. This is the first pilot-study specifically evaluating the impact of staff training and wearing safety vests on the reduction of interruptions during medication preparation and double-checking.

Abstract
OBJECTIVE Preclinical evidence suggests that increased cholesterol levels might be involved in the pathophysiology of osteoarthritis of the hand (HOA), but evidence from observational studies remains scarce. We aimed to analyse the association between hyperlipidaemia and incident HOA. DESIGN We conducted a matched (1:1) case-control study using the UK-based Clinical Practice Research Datalink (CPRD). Cases were patients aged 30-89 years with an incident diagnosis of HOA between 1995 and 2014. In multivariable conditional logistic regression analyses, we calculated odds ratios (OR) for incident HOA in patients with hyperlipidaemia, categorized by gender, age, previous duration of hyperlipidaemia, and recent statin treatment. RESULTS Among 19,590 cases and 19,590 controls, we observed an increased risk of HOA in patients with hyperlipidaemia (OR 1.37, 95% confidence intervals (CI) 1.28-1.47), when compared to patients without hyperlipidaemia. Thus, of all HOA cases in our study population, 3.6% may have been attributable to the presence of hyperlipidaemia (population attributable risk). Most patients with HOA were elderly, but the strength of the association between HOA and hyperlipidaemia inversely correlated with increasing age, with the highest OR of 1.72 (95% CI 1.24-2.38) in patients aged 29-49 years. Categorization by previous hyperlipidaemia duration, as well as sub-classification of patients with hyperlipidaemia into those with and without recent statin use did not meaningfully change the effect estimate. CONCLUSIONS Our results suggest that hyperlipidaemia may be an independent risk factor for new onset HOA.
