Real-world expenditures and survival time after CAR-T treatment for large B-cell lymphoma in Switzerland: a retrospective study using insurance claims data.

AIM OF THE STUDY: Newly approved therapies with high and uncertain budget impact pose challenges to public health care systems worldwide. One recent example is chimeric antigen receptor T cell (CAR-T) therapies for adults with large B-cell lymphoma (LBCL). This study's primary objective is to examine the expenditures of Swiss public payers before, during, and after CAR-T cell therapy in patients with LBCL aged ≥30 years. Its secondary objective is to analyse 24-month survival rates. METHODS: This retrospective observational data analysis used the administrative databases of the Swiss health insurers Concordia, CSS, Groupe Mutuel, Helsana, ÖKK, Sanitas, SWICA, Sympany, and Visana. These health insurers or groups provide mandatory health insurance to approximately 78% of Swiss residents in 2021. Using the relevant procedure codes, we identified CAR-T therapies administered between October 2018 (first approval) and June 2021 (treatment identification cut-off). Patients aged <30 years were excluded because they might be treated for pediatric acute lymphoblastic leukaemia. Expenditures were categorised as pre-infusion, peri-infusion (excluding CAR-T therapy acquisition costs), and post-infusion based on the time of service provision. Overall survival rates were estimated using the Kaplan-Meier method. RESULTS: This study identified 81 patients aged ≥30 years, with a median follow-up period for censored observations of 27 months (interquartile range: 21-31 months). The median age group was 70-74, and 60% of patients were male. Mean healthcare expenditures per patient per month amounted to CHF 8,115-22,564 pre-infusion, CHF 38,490 peri-infusion, and CHF 5,068-11,342 post-infusion. For the total peri- and post-infusion period (i.e. 1-month before infusion to 23 months after infusion), mean healthcare expenditures amounted to CHF 215,737. The 24-month overall survival rate was 48% (95% confidence interval: 38-61%). CONCLUSIONS: Healthcare expenditures after CAR-T cell infusion are relatively high compared to previous estimates of patients with LBCL in the last year of treatment. Further research is needed to understand the drivers behind these post-infusion expenditures. Especially, clinical data should be used to assess the time until disease progression. The analysis of 24-month overall survival is consistent with results from the pivotal trials. Our findings stress the importance of post-approval studies to monitor real-world expenditures and outcomes related to innovative therapies.

Continuity of care and treatment intensity at the end of life in Swiss cancer patients.

BACKGROUND: Continuity of care (COC) was shown to be associated with fewer hospitalizations. We aimed to evaluate whether COC was associated with intensive intervention(s) at the end of life (IEOL), a preference-sensitive outcome, in cancer patients. METHODS: The study is based on claims data of patients with incident use of anti-neoplastics in Switzerland. COC Index, Usual Provider Continuity score, Sequential Continuity index and Modified Modified Continuity Index were calculated based on consultations with the usual ambulatory care physician. Treatment intensity was evaluated in the last 6 months of life, and COC was evaluated in months 18-6 before death in those who died between 24 and 54 months after incident cancer. IEOL comprised life-sustaining interventions (cardiac catheterization, cardiac assistance device implantation, pulmonary artery wedge monitoring, cardiopulmonary resuscitation/cardiac conversion, gastrostomy, blood transfusion, dialysis, mechanical ventilator utilization and intravenous antibiotics) and measures specifically used in cancer patients (last dose of chemotherapy ≤14 days of death, a new chemotherapy regimen starting <30 days before death, ≥1 emergency visit in the last month of life, ≥1 hospital admission or spending >14 days in hospital in the last month of life and death in an acute-care hospital). RESULTS: All COC scores were inversely associated with the occurrence of an IEOL, as were older age, homecare nursing utilization and density of ambulatory care physicians. For COC Index, odds ratio was 0.55 (95% confidence interval 0.37-0.83). CONCLUSIONS: COC scores were consistently and inversely related to IEOL. The study supports efforts to improve COC for cancer patients at their end of life.

Opioid prescriptions after knee replacement: a retrospective study of pathways and prognostic factors in the Swiss healthcare setting.

OBJECTIVES: The optimal use of opioids after knee replacement (KR) remains to be determined, given the growing evidence that opioids are no more effective than other analgesics and that their adverse effects can impair quality of life. Therefore, the objective is to examine opioid prescriptions after KR. DESIGN: In this retrospective study, we used descriptive statistics and estimated the association of prognostic factors using generalised negative binomial models. SETTING: The study is based on anonymised claims data of patients with mandatory health insurance at Helsana, a leading Swiss health insurance. PARTICIPANTS: Overall, 9122 patients undergoing KR between 2015 and 2018 were identified. PRIMARY AND SECONDARY OUTCOME MEASURES: Based on reimbursed bills, we calculated the dosage (morphine equivalent dose, MED) and the episode length (acute: <90 days; subacute: ≥90 to <120 days or <10 claims; chronic: ≥90 days and ≥10 claims or ≥120 days). The incidence rate ratios (IRRs) for postoperative opioids were calculated. RESULTS: Of all patients, 3445 (37.8%) received opioids in the postoperative year. A large majority had acute episodes (3067, 89.0%), 2211 (65.0%) had peak MED levels above 100 mg/day and most patients received opioids in the first 10 postoperative weeks (2881, 31.6%). Increasing age (66-75 and >75 vs 18-65) was associated with decreased IRR (0.776 (95% CI 0.7 to 0.859); 0.723 (95% CI 0.649 to 0.805)), whereas preoperative non-opioid analgesics and opioids were associated with higher IRR (1.271 (95% CI 1.155 to 1.399); 3.977 (95% CI 4.409 to 3.591)). CONCLUSION: The high opioid demand is unexpected given that current recommendations advise using opioids only when other pain therapies are ineffective. To ensure medication safety, it is important to consider alternative treatment options and ensure that benefits outweigh potential risks.

Factors associated with health-related quality of life among home-dwelling older adults aged 75 or older in Switzerland: a cross-sectional study.

BACKGROUND: HRQoL is an indicator of individuals' perception of their overall health, including social and environmental aspects. As a multidimensional concept, HRQoL can be influenced by a multitude of factors. Studies of HRQoL and factors associated with it among home-dwelling older adults have often been limited to inpatient settings or to a sub-population with a chronic disease. Studying HRQoL and its correlating factors among this population, by providing an ecological lens on factors beyond the individual level, can provide a better understanding of the construct and the role of the environment on how they perceive their HRQoL. Thus, we aimed to assess the HRQoL and investigate the correlates of HRQOL among home-dwelling older adults, guided by the levels of the ecological model. METHODS: This is a cross-sectional population survey conducted in 2019 in Canton Basel-Landschaft, in northwestern Switzerland, and includes a sample of 8786 home-dwelling older adults aged 75 and above. We assessed HRQoL by using the EQ-index and the EQ-VAS. The influence of independent variables at the macro, meso and micro level on HRQoL was tested using Tobit multiple linear regression modelling. RESULTS: We found that having a better socio-economic status as denoted by higher income, having supplementary insurance and a higher level of education were all associated with a better HRQoL among home-dwelling older adults. Furthermore, being engaged in social activities was also related to an improved HRQoL. On the other hand, older age, female gender, presence of multimorbidity and polypharmacy as well as social isolation and loneliness were found to all have a negative impact on HRQoL. CONCLUSIONS: Understanding factors related to HRQoL by using an ecological lens can help identify factors beyond the individual level that impact the HRQoL of home-dwelling older adults. Our study emphasises the importance of social determinants of health and potential disparities that exists, encouraging policymakers to focus on policies to reduce socio-economic disparities using a life-course approach, which consequently could also impact HRQoL in later stages of life.

Therapy Patterns and Surveillance Measures of Inflammatory Bowel Disease Patients beyond Disease-Related Hospitalization: A Claims-Based Cohort Study.

Introduction: Medical care and surveillance of inflammatory bowel disease (IBD) patients have been shown to be far from satisfactory. Data on therapy patterns and surveillance measures in IBD patients are scarce. We, therefore, aimed to compare the therapy patterns and surveillance management of IBD patients in the year before and after IBD-related hospitalization. Methods: We examined medical therapy, surveillance management (influenza vaccination, dermatologist visits, Pap smear screening, creatinine measurements, iron measurements, and ophthalmologist visits) and healthcare utilization in 214 ulcerative colitis (UC) and 259 Crohn's disease (CD) patients who underwent IBD-related hospitalization from 2012 to 2014. Results: IBD-related drug classes changed in 64.5% of IBD patients following hospitalization. During the 1-year follow-up period, biological treatment increased in UC and CD patients, while steroid use decreased. Following hospitalization, 63.1% of UC and 27.0% of CD patients received 5-ASA. Only 21.6% of all IBD patients had a flu shot, and 19.6% of immunosuppressed IBD patients were seen by a dermatologist in the follow-up; other surveillance measures were more frequent. Surveillance before hospital admission and consultations by gastroenterologists were strongly correlated with surveillance during the postoperative follow-up, while gender and diagnosis (UC vs. CD) were not. During the 1-year follow-up, 20.5% of all IBD patients had no diagnostic or disease-monitoring procedure. Discussion/Conclusion: Surveillance measures for IBD patients are underused in Switzerland. Further research is needed to examine the impact of annual screenings and surveillance on patient outcomes.

Use of Prescribed Drugs to Treat Chronic Diseases during Pregnancy in Outpatient Care in Switzerland between 2014 and 2018: Descriptive Analysis of Swiss Health Care Claims Data.

Evidence on the use of drugs during pregnancy in Switzerland is lacking. We aimed to evaluate the utilisation of drugs to treat chronic diseases during pregnancy in Switzerland. We identified all pregnancies (excluding abortions) in Swiss Helsana claims data (2014-2018). In those, we identified all claims for drugs to treat a chronic disease, which typically affects women of childbearing age. Potentially teratogenic/fetotoxic drugs were evaluated during specific risk periods. Results were demographically weighted relative to the Swiss population. We identified claims for ≥1 drug of interest during 22% of 369,371 weighted pregnancies. Levothyroxine was most frequently claimed (6.6%). Antihypertensives were claimed during 5.3% (3.9% nifedipine in T3). Renin-Angiotensin-Aldosterone System (RAAS) inhibitors were dispensed to 0.3/10,000 pregnancies during trimester 2 (T2) or trimester 3 (T3). Insulin was claimed during 3.5% of pregnancies, most frequently in T3 (3.3%). Exposure to psychotropic drugs was 3.8% (mostly Selective serotonin reuptake inhibitors (SSRIs)) and to drugs for obstructive airway diseases 3.6%. Traditional immunosuppressants (excluding corticosteroids) were claimed during 0.5% (mainly azathioprine and hydroxychloroquine), biologic immunosuppressants (Tumour necrosis factor-alpha (TNF-alpha) inhibitors and interleukin inhibitors) during 0.2%, and drugs to treat multiple sclerosis during 0.09% of pregnancies. Antiretrovirals were claimed during 0.15% of pregnancies. Patterns of drug claims were in line with treatment recommendations, but relatively rare events of in utero exposure to teratogenic drugs may have had severe implications for those involved.

Does hospital volume affect outcomes after abdominal cancer surgery: an analysis of Swiss health insurance claims data.

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.

Change in Colorectal Cancer Tests Submitted for Reimbursement in Switzerland 2012-2018: Evidence from Claims Data of a Large Insurance.

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.

Surgical procedures in inpatient versus outpatient settings and its potential impact on follow-up costs.

OBJECTIVE: We examined real-world effects of cantonal legislations to direct surgery patients from the inpatient to the outpatient setting in Switzerland. METHODS: Analyses were based on claims data of the Helsana Group, a leading Swiss health insurance. The study population consisted of 13'145 (in 2014), 12'455 (in 2016), and 12'875 (in 2018) insured persons aged >18 years who had haemorrhoidectomy, inguinal hernia repair, varicose vein surgery, knee arthroscopy/meniscectomy or surgery of the cervix/uterus. We assessed the proportion of inpatient procedures, index costs, length of hospital stays, outpatient costs and hospitalizations during follow-up, stratified by procedure, in-/outpatient setting, and the presence (enacted/effective in 2018) of a cantonal legislation. We used difference-in-differences methods to study the impact of cantonal legislations. RESULTS: Overall, the proportion of procedures performed in the inpatient setting decreased between 2014 and 2018 (p < 0.001). The decrease between 2016 and 2018 was significantly steeper in cantons with a legislation (p < 0.001; effect size: 0.57; 95% CI: 0.51, 0.64), leading to steeper decreases in healthcare costs of index procedures in cantons with a legislation, with no impact on length of hospital stays. The legislation also had no impact on outpatient costs or hospitalizations during follow-up. CONCLUSIONS: The cantonal legislations achieved the intended effects of inpatient surgery substitution by outpatient surgery, with no evidence suggesting negative effects on costs or hospitalizations during follow-up.

Potentially inappropriate proton-pump inhibitor prescription in the general population: a claims-based retrospective time trend analysis.

BACKGROUND: Proton-pump inhibitors (PPI) are among the most prescribed drugs worldwide, and a large body of evidence raises concerns about their inappropriate use. Previous estimates of inappropriate use varied due to different definitions and study populations. AIMS: We aimed to measure the population-based incidence and time trends of PPI and potentially inappropriate PPI prescriptions (PIPPI) with a novel method, continuously assessing excessive cumulative doses based on clinical practice guidelines. We also assessed association of patient characteristics with PPI prescriptions and PIPPI. METHODS: This was an observational study based on a large insurance claims database of persons aged >18 years with continuous claims records of ⩾12 months. The observation period was January 2012 to December 2017. We assessed the incidence and time trends of PPI prescriptions and PIPPI based on doses prescribed, defining ⩾11.5 g of pantoprazole dose equivalents during any consecutive 365 days (average daily dose >31 mg) as inappropriate. RESULTS: Among 1,726,491 eligible persons, the annual incidence of PPI prescriptions increased from 19.7% (2012) to 23.0% (2017), (p = <0.001), and the incidence of PIPPI increased from 4.8% (2013) to 6.4% (2017), (p = <0.001). Age, male gender, drugs with bleeding risk and multimorbidity were independent determinants of PIPPI (p = <0.001 for all). CONCLUSIONS: This study provides evidence that one of the most prescribed drug groups is commonly prescribed inappropriately in the general population and that this trend is increasing. Multimorbidity and drugs with bleeding risks were strong determinants of PIPPI. Addressing PPI prescriptions exceeding guideline recommendations could reduce polypharmacy and improve patient safety.

Temporal trends and regional disparities in cancer screening utilization: an observational Swiss claims-based study.

BACKGROUND: We examined colorectal, breast, and prostate cancer screening utilization in eligible populations within three data cross-sections, and identified factors potentially modifying cancer screening utilization in Swiss adults. METHODS: The study is based on health insurance claims data of the Helsana Group. The Helsana Group is one of the largest health insurers in Switzerland, insuring approximately 15% of the entire Swiss population across all regions and age groups. We assessed proportions of the eligible populations receiving colonoscopy/fecal occult blood testing (FOBT), mammography, or prostate-specific antigen (PSA) testing in the years 2014, 2016, and 2018, and calculated average marginal effects of individual, temporal, regional, insurance-, supply-, and system-related variables on testing utilization using logistic regression. RESULTS: Overall, 8.3% of the eligible population received colonoscopy/FOBT in 2014, 8.9% in 2016, and 9.2% in 2018. In these years, 20.9, 21.2, and 20.4% of the eligible female population received mammography, and 30.5, 31.1, and 31.8% of the eligible male population had PSA testing. Adjusted testing utilization varied little between 2014 and 2018; there was an increasing trend of 0.8% (0.6-1.0%) for colonoscopy/FOBT and of 0.5% (0.2-0.8%) for PSA testing, while mammography use decreased by 1.5% (1.2-1.7%). Generally, testing utilization was higher in French-speaking and Italian-speaking compared to German-speaking region for all screening types. Cantonal programs for breast cancer screening were associated with an increase of 7.1% in mammography utilization. In contrast, a high density of relevant specialist physicians showed null or even negative associations with screening utilization. CONCLUSIONS: Variation in cancer screening utilization was modest over time, but considerable between regions. Regional variation was highest for mammography use where recommendations are debated most controversially, and the implementation of programs differed the most.

Continuity of Care in Swiss Cancer Patients Using Claims Data.

BACKGROUND: Continuity of care is positively associated with beneficial patient outcomes. Data on the level of continuity of care in the ambulatory setting in Switzerland are lacking. AIM: The aim of this study was to evaluate continuity of care in Swiss cancer patients based on routine data of mandatory health insurance using four established continuity scales. METHODS: Retrospective analysis of Swiss claims data (N=23'515 patients with incident use of antineoplastics). The Usual Provider Continuity score, the Modified Modified Continuity Index, the Continuity of Care index, and the Sequential Continuity Index were analyzed based on consultations with general practitioners (GPs), physician specialists and ambulatory hospital wards. RESULTS: Using information of health insurance claims, the number of consultations and the general level of continuity of care in Swiss cancer patients are high. Continuity of care scores were significantly associated with sociodemographic and regional factors. When focusing on consultations with GPs only, all four scores consistently showed high values indicating high levels of continuity. Continuity with general practitioners was associated with lower costs and lower risks for hospitalization and death. CONCLUSION: This is the first study giving insight into continuity of care in Swiss cancer patients. The present study shows that continuity of care is measurable using health insurance claims data. It indicates that continuity with general practitioners is associated with a beneficial outcome.

Follow-Up Ileocolonoscopy Is Underused in Crohn's Disease Patients after Ileocecal Resection despite Higher Total and Inpatient Health-Care Costs Compared to Controls.

BACKGROUND: Postoperative recurrence is frequently observed after ileocecal resection in Crohn's disease (CD) patients. Since 2010, endoscopy within 1 year is considered the gold standard for its diagnosis. However, if and how frequent such endoscopies are performed in clinical practice remains unknown. METHODS: We analyzed 1-year follow-up data on CD patients who underwent ileocecal resection between 2012 and 2014 and compared them with hospitalized, non-resected CD controls. Data were extracted from the Helsana database. Helsana is one of the largest Swiss health insurance companies providing coverage for 1.2 million individuals. RESULTS: A total of 645 CD patients were identified with ≥1 hospitalization between 2012 and 2014 and a follow-up of 1 year. Of these, 79 (12.2%) underwent ileocecal resection. Although endoscopy rates increased over time and were higher in patients with resection versus controls (p = 0.029), in only 54.4% a 1-year follow-up ileocolonoscopy was performed. Postoperative prophylaxis with anti-tumor necrosis factor or azathioprine was prescribed in 63.3%. Female sex and age >60 years were independent predictors for not receiving prophylaxis (odds ratio [OR] 0.36, p = 0.048, and OR 0.2, p = 0.022). Patients with resection had significantly lower numbers of rehospitalizations (1.2 vs. 1.8, p = 0.021), with resection being an independent negative predictor for number of rehospitalizations in a Poisson regression model (incident risk ratio 0.64, p = 0.029). However, disease-related surgery was more often the cause for rehospitalization after resection versus controls (47.6 vs. 22.1%, p = 0.015). Total and inpatient health-care costs were higher in these patients. CONCLUSION: Endoscopies are underused after ileocecal resection. This contrasts current guidelines. Physicians should be aware of this underuse and perform follow-up examinations more often.

Increased risk of adverse events in non-cancer patients with chronic and high-dose opioid use-A health insurance claims analysis.

BACKGROUND: Chronic and high dose opioid use may result in adverse events. We analyzed the risk associated with chronic and high dose opioid prescription in a Swiss population. METHODS: Using insurance claims data covering one-sixth of the Swiss population, we analyzed recurrent opioid prescriptions (≥2 opioid claims with at least 1 strong opioid claim) between 2006 and 2014. We calculated the cumulative dose in milligrams morphine equivalents (MED) and treatment duration. Excluded were single opioid claims, opioid use that was cancer treatment related, and opioid use in substitution programs. We assessed the association between the duration of opioid use, prescribed opioid dose, and benzodiazepine use with emergency department (ED) visits, urogenital and pulmonary infections, acute care hospitalization, and death at the end of the episode. RESULTS: In 63,642 recurrent opioid prescription episodes (acute 38%, subacute 7%, chronic 25.8%, very chronic (>360 days) episodes 29%) 18,336 ED visits, 30,209 infections, 19,375 hospitalizations, and 9,662 deaths occurred. The maximum daily MED dose was <20 mg in 15.8%, 20-<50 mg in 16.6%, 50-<100 mg in 21.6%, and ≥100 mg in 46%. Compared to acute episodes (<90 days), episode duration was an independent predictor of ED visits (chronic OR 1.09 (95% CI 1.03-1.15), very chronic (>360 days) OR 1.76 (1.67-1.86)) for adverse effects; infections (chronic OR 1.74 (1.66-1.82), very chronic 4.16 (3.95-4.37)), and hospitalization (chronic: OR 1.22 (1.16-1.29), very chronic OR 1.82 (1.73-1.93)). The risk of death decreased over time (very chronic OR 0.46 (0.43-0.50)). A dose dependent increased risk was observed for ED visits, hospitalization, and death (≥100mg daily MED OR 1.21 (1.13-1.29), OR 1.29 (1.21-1.38), and OR 1.67, 1.50-1.85, respectively). A concomitant use of benzodiazepines increased the odds for ED visits by 46% (OR 1.46, 1.41-1.52), infections by 44% (OR 1.44, 1.41-1.52), hospitalization by 12% (OR 1.12, 1.07-1.1), and death by 45% (OR 1.45, 1.37-1.53). CONCLUSION: The length of opioid use and higher prescribed morphine equivalent dose were independently associated with an increased risk for ED visits and hospitalizations. The risk for infections, ED visits, hospitalizations, and death also increased with concomitant benzodiazepine use.

Regional differences in healthcare costs at the end of life: an observational study using Swiss insurance claims data.

OBJECTIVES: We evaluated healthcare cost differences at the end of life (EOL) between language regions in Switzerland, accounting for a comprehensive set of variables, including treatment intensity. METHODS: We evaluated 9716 elderly who died in 2014 and were insured at Helsana Group, with data on final cause of death provided by the Swiss Federal Statistical Office. EOL healthcare costs and utilization, ≥ 1 ICU admission and 10 life-sustaining interventions (cardiac catheterization, cardiac assistance device implantation, pulmonary artery wedge monitoring, cardiopulmonary resuscitation, gastrostomy, blood transfusion, dialysis, mechanical ventilation, intravenous antibiotics, cancer chemotherapies) reimbursed by compulsory insurance were examined. RESULTS: Taking into consideration numerous variables, relative cost differences decreased from 1.27 (95% CI 1.19-1.34) to 1.06 (CI 1.02-1.11) between the French- and German-speaking regions, and from 1.12 (CI 1.03-1.22) to 1.08 (CI 1.02-1.14) between the Italian- and German-speaking regions, but standardized costs still differed. Contrary to individual factors, density of home-care nurses, treatment intensity, and length of inpatient stay explain a substantial part of these differences. CONCLUSIONS: Both supply factors and health-service provision at the EOL vary between Swiss language regions and explain a substantial proportion of cost differences.

Evidence-based quality indicators for primary healthcare in association with the risk of hospitalisation: a population-based cohort study in Switzerland.

OBJECTIVES: The quality of ambulatory care in Switzerland is widely unknown. Therefore, this study aimed to evaluate the recently proposed quality indicators (QIs) based on a nationwide healthcare claims database and determine their association with the risk of subsequent hospitalisation at patient-level. DESIGN: Retrospective cohort study. SETTING: Inpatient and outpatient claims data of a large health insurance in Switzerland covering all regions and population strata. PARTICIPANTS: 520 693 patients continuously insured during 2015 and 2016. MEASURES: A total of 24 QIs were obtained by adapting the existing instruments to the Swiss national context and measuring at patient-level. The association between each QI and hospitalisation in the subsequent year was assessed using multiple logistic regression models. RESULTS: The proportion of patients with good adherence to QIs was high for the secondary prevention of diabetes and myocardial infarction (glycated haemoglobin (HbA1c) control, 89%; aspirin use, 94%) but relatively low for polypharmacy (53%) or using potentially inappropriate medications (PIMs) in the elderly (PIM, 33%). Diabetes-related indicators such as the HbA1c control were significantly associated with a lower risk of hospitalisation (OR, 0.87; 95% CI, 0.80 to 0.95), whereas the occurrence of polypharmacy and PIM increased the risk of hospitalisation in the following year (OR, 1.57/1.08; 95% CI, 1.51 to 1.64/1.05 to 1.12). CONCLUSIONS: This is the first study to evaluate the recently presented QIs in Switzerland using nationwide real-life data. Our study suggests that the quality of healthcare, as measured by these QIs, varied. The majority of QIs, in particular QIs reflecting chronic care and medication use, are considered beneficial markers of healthcare quality as they were associated with reduced risk of hospitalisation in the subsequent year. Results from this large practical test on real-life data show the feasibility of these QIs and are beneficial in selecting the appropriate QIs for healthcare implementation in general practice.

Variation of colorectal, breast and prostate cancer screening activity in Switzerland: Influence of insurance, policy and guidelines.

Variation in utilization of healthcare services is influenced by patient, provider and healthcare system characteristics. It could also be related to the evidence supporting their use, as reflected in the availability and strength of recommendations in clinical guidelines. In this study, we analyzed the geographic variation of colorectal, breast and prostate cancer screening utilization in Switzerland and the influence of available guidelines and different modifiers of access. Colonoscopy, mammography and prostate specific antigen (PSA) testing use in eligible population in 2014 was assessed with administrative claims data. We ran a multilevel multivariable logistic regression model and calculated Moran's I and regional level median odds ratio (MOR) statistics to explore residual geographic variation. In total, an estimated 8.1% of eligible persons received colonoscopy, 22.3% mammography and 31.3% PSA testing. Low deductibles, supplementary health insurance and enrollment in a managed care plan were associated with higher screening utilization. Cantonal breast cancer screening programs were also associated with higher utilization. Spatial clustering was observed in the raw regional utilization of all services, but only for prostate cancer screening in regional residuals of the multilevel model. MOR was highest for prostate cancer screening (1.24) and lowest for colorectal cancer screening (1.16). The reasons for the variation of the prostate cancer screening utilization, not recommended routinely without explicit shared decision-making, could be further investigated by adding provider characteristics and patient preference information. This first cross-comparison of different cancer screening patterns indicates that the strength of recommendations, mediated by specific health policies facilitating screening, may indeed contribute to variation.

Systematic analysis of therapeutic patterns and healthcare use during 12 months before inflammatory bowel disease-related hospitalization in Switzerland.

BACKGROUND AND AIMS: Given the lack of data, we aimed to systematically analyze therapeutic patterns and health resource utilization in the year before inflammatory bowel disease (IBD)-related hospitalization. METHODS: Based on claims data of the Helsana health insurance group, therapy patterns and health resource utilization were assessed, and costs reimbursed by mandatory basic health insurance were calculated during a one-year period before an index hospitalization between 1 January 2013 to 31 December 2015. RESULTS: We analyzed 344 IBD patients (140 ulcerative colitis [40.7%], 204 Crohn's disease [59.3%]). Drug regimens applied in the year before index hospitalization were as follows: no IBD drugs (43.6% ulcerative colitis, 43.1% Crohn's disease); 5-ASA (45.7% ulcerative colitis, 19.1% Crohn's disease); local steroids (17.9% ulcerative colitis, 17.6% Crohn's disease); systemic steroids (38.6% ulcerative colitis, 29.4% Crohn's disease); immunomodulators (10.7% ulcerative colitis, 18.1% Crohn's disease); biologics (10% ulcerative colitis, 24% Crohn's disease); and calcineurin inhibitors (2.1% ulcerative colitis, 1.5% Crohn's disease). Forty-five percent of ulcerative colitis patients and 31.4% of Crohn's disease patients had no diagnostic procedures [computed tomography (CT), MRI, radiograph, sonography, colonoscopy, and calprotectin] in the year before hospitalization. Total annual health care costs before index hospitalization was EUR 4060 (interquartile range (IQR) 2360-7390) for ulcerative colitis and EUR 4900 (IQR 1520-14 880) for Crohn's disease patients, respectively. CONCLUSIONS: Over 40% of ulcerative colitis and Crohn's disease patients did not receive any treatment in the year before index hospitalization. Efforts should be launched to timely diagnose and adequately treat IBD outpatients.

Real-World Data on Topical Therapies and Annual Health Resource Utilization in Hospitalized Swiss Patients with Ulcerative Colitis.

OBJECTIVES: Topical treatment with aminosalicylates and/or budesonide was shown to be highly effective in patients with ulcerative colitis (UC), while reducing the likelihood of systemic adverse effects. However, previous research has shown that topical treatment is clearly underused. We aimed to evaluate the use of topical therapy in the real-world setting. METHODS: This is an observational study based on claims data of 201 Swiss adult patients who were hospitalized for UC between 2012 and 2014 and who were then followed for 1 year. A variety of factors presumably associated with topical treatment were examined. Annual health care utilization (UC-related medications, diagnostic procedures, consultations, and rehospitalizations) of patients with versus without topical therapy was compared. RESULTS: Of the 201 hospitalized UC patients, 82 (40.8%) were treated with topical 5-acetylsalicylic acid (ASA) and/or topical rectal steroids. The main factors significantly and positively associated with receiving topical treatment were the use of topical treatment in the year prior to the hospitalization, receiving oral 5-ASA, and living in an urban area. The mode of administration was further related to the language area. Patients with topical therapy significantly more often received other UC-related medications, such as combinations with systemic steroids. They significantly more often underwent colonoscopies and calprotectin measurements, and more often consulted a gastroenterologist in the follow-up, while there was no significant difference regarding rehospitalizations. CONCLUSIONS: Topical treatment is underused in patients with UC, which stands in contrast to the current European Crohn's and Colitis Organization guidelines. Patients' preferences and considerations need to be taken into account when prescribing medical therapy.

Opioid Prescription in Switzerland: Appropriate Comedication use in Cancer and Noncancer Pain.

BACKGROUND: In Europe, limited information on the use of opioids is available. OBJECTIVES: To assess how guideline recommendations to manage opioid-related adverse events were followed in cancer- and noncancer-related opioid use. STUDY DESIGN: Analysis of health insurance data of one of the major health insurers in Switzerland. SETTING: All opioid claims between 2006 and 2014. METHODS: Opioid episodes were cancer-related when cancer treatments were used within ± 3 months of the first opioid claim. Recurrent strong episodes were defined as >/= 2 opioid claims with at least one strong opioid claim. Episode duration were acute (< 90 days), subacute, or chronic (>/= 120 days >/= 90 days +>/= 10 claims). RESULTS: Out of 591,633 opioid episodes 76,968 (13%) were recurrent episodes: 94% were noncancer related (83% in recurrent episodes) and 6% cancer related (17% recurrent). Chronic opioid use was observed in 55% (noncancer) and 58% (cancer) recurrent episodes. Recommended laxatives were used in 50% noncancer and in 67% cancer episodes. Antiemetic drugs were used in 54% noncancer and in 83% cancer episodes. Not recommended coprescription of benzodiazepines was observed in 34% recurrent noncancer and 46% cancer episodes. LIMITATIONS: No clinical information was available to assess the indication for opioid use. CONCLUSIONS: In this study, opioids were primarily used outside the context of cancer-related treatment. In noncancer-related opioid use, we found a substantial higher proportion without recommended laxative and antiemetic medications. Coprescription of benzodiazepines may increase the risk for opioid overdose and was present in one-third of the noncancer episodes and in almost every second cancer episode.
