Background Micronutrient laboratory tests (MLT) are increasing in many healthcare systems. This study assessed time trends of annual MLT incidence in the Swiss population and examined the frequency of specific MLT, defined as the number of yearly tests performed in individual persons. Methods For annual time trends, we used a longitudinal design with a seven-year observation period (2012–2018) and for yearly testing frequency we used a cross-sectional design (2018 only). The database consisted of nationwide insurance claims from adult persons. Results Persons with MLT compared to persons without were older (mean age 57.1 years vs 48.6 years) and to a higher proportion female (65.1% vs 45.5%). Between 2012 and 2018, we included 6.7 million person years and found an increase in the proportion of persons receiving any MLT from 24.5% to 35.0%. Tests with strongest absolute increase during the observation period were vitamin D (from 7.4% of persons to 20.4%), vitamin B12 (from 9.0% to 17.6%) and ferritin (from 17.4% to 26.6%). In 2018, vitamin D and vitamin B12 tests were performed more than once in 4.5% and 3.3% of the population, respectively. Conclusion We found that the Swiss population undergoes MLT with high and increasing frequency. Testing for vitamin D, vitamin B12 and ferritin is very common and of questionable appropriateness.
Background Medical treatment quality has been shown to be better in high volume than in low volume hospitals. However, this relationship has not yet been confirmed in abdominal cancer in Switzerland and is relevant for referral of patients and healthcare planning. Thus, the present study investigates the association between hospital volumes for surgical resections of colon, gastric, rectal, and pancreatic carcinomas and outcomes. Methods This retrospective analysis is based on anonymized claims data of patients with mandatory health insurance at Helsana Group, a leading health insurance in Switzerland. Outcome parameters were length of hospital stay, mortality and cost during the inpatient stay as well as at 1-year follow-up. Hospital volume information was derived from the Quality Indicators dataset provided by the Swiss Federal Office of Public Health. The impact of hospital volume on the different treatment outcomes was statistically tested using generalized estimating equations (GEE) models, taking into account the non-independence of observations from the same hospital. Results The studies included 2′859 resections in patients aged 18 years and older who were hospitalized for abdominal cancer surgery between 2014 and 2018. Colon resections were the most common procedures (n = 1′690), followed by rectal resections (n = 709). For rectal, colon and pancreatic resections, an increase in the mean number of interventions per hospital and a reduction of low volume hospitals could be observed. For the relationship between hospital volume and outcomes, we did not observe a clear dose-response relationship, as no significantly better outcomes were observed in the higher-volume category than in the lower-volume category. Even though a positive “routine effect” cannot be excluded, our results suggest that even hospitals with low volumes are able to achieve comparable treatment outcomes to larger hospitals. Conclusion In summary, this study increases transparency on the relationship between hospital volume and treatment success. It shows that simple measures such as defining a minimum number of procedures only might not lead to the intended effects if other factors such as infrastructure, the operating team or aggregation level of the available data are not taken into account.
Objectives: Guidelines recommend colorectal cancer (CRC) screening by fecal occult blood test (FOBT) or colonoscopy. In 2013, Switzerland introduced reimbursement of CRC screening by mandatory health insurance for 50-69-years-olds, after they met their deductible. We hypothesized that the 2013 reimbursement policy increased testing rate.Methods: In claims data from a Swiss insurance, we determined yearly CRC testing rate among 50-75-year-olds (2012–2018) and the association with socio-demographic, insurance-, and health-related covariates with multivariate-adjusted logistic regression models. We tested for interaction of age (50–69/70–75) on testing rate over time.Results: Among insurees (2012:355′683; 2018:348′526), yearly CRC testing rate increased from 2012 to 2018 (overall: 8.1–9.9%; colonoscopy: 5.0–7.6%; FOBT: 3.1–2.3%). Odds ratio (OR) were higher for 70–75-year-olds (2012: 1.16, 95%CI 1.13–1.20; 2018: 1.05, 95%CI 1.02–1.08). Deductible interacted with changes in testing rate over time (p < 0.001). The increase in testing rate was proportionally higher among 50-69-years-olds than 70-75-year-olds over the years.Conclusions: CRC testing rate in Switzerland increased from 2012 to 2018, particularly among 50-69-years-olds, the target population of the 2013 law. Future studies should explore the effect of encouraging FOBT or waiving deductible.
Purpose The newly developed calcitonin gene-related peptide (CGRP) antagonists were recently launched on the US and European market, with Switzerland as the second country worldwide. To enable forthcoming comparisons with established migraine therapy, the aim of this study was to provide a comprehensive picture of migraine (prophylactic) treatment patterns. Recent data in daily clinical practice are lacking. Patients and methods This population-based cohort study included enrollees from a Swiss Healthcare Insurance Database with at least one triptan prescription in 2015. Treatment patterns were defined by assessing subsequent triptan and prophylactic medication use (after index prescription for triptan) within the following year, divided into four quarters. Results Triptans were used by 10,090 patients (1.3%) in 2015. Most of them used triptan only (82.6%), 12.9% changed the treatment between triptan and prophylactics, and 4.5% received both in combination within 1year. Among triptan users with ≥1 prophylactic prescription in the first quarter, 48.6% used beta-blockers (BB), 40.7% “other prophylactics than BB (eg, topiramate)”, and 10.7% “a combination of both”. Most patients who received both BB and other prophylactics in the first quarter used this drug combination continuously over all four quarters. Conclusion This study provides comprehensive data on treatment patterns prior to the introduction of a new drug class in migraine therapy. The majority of triptan users had no prophylactic medication therapy; however, a small, but relevant group used BB and other prophylactics concurrently in all quarters. Findings quantify the population in potential need for optimized migraine therapy, ie, the potential target population of the novel CGRP-targeted drugs.
