Outcomes and costs of ureteroscopy, extracorporeal shockwave lithotripsy, and percutaneous nephrolithotomy for the treatment of urolithiasis: an analysis based on health insurance claims data in Germany.

PURPOSE: Comparisons of ureteroscopy (URS), extracorporeal shockwave lithotripsy (SWL), and percutaneous nephrolithotomy (PCNL) for urolithiasis considering long-term health and economic outcomes based on claims data are rare. Our aim was to analyze URS, SWL, and PCNL regarding complications within 30 days, re-intervention, healthcare costs, and sick leave days within 12 months, and to investigate inpatient and outpatient SWL treatment as the latter was introduced in Germany in 2011. METHODS: This retrospective cohort study based on German health insurance claims data included 164,203 urolithiasis cases in 2008-2016. We investigated the number of complications within 30 days, as well as time to re-intervention, number of sick leave days and hospital and ambulatory health care costs within a 12-month follow-up period. We applied negative binomial, Cox proportional hazard, gamma and two-part models and adjusted for patient variables. RESULTS: Compared to URS cases, SWL and PCNL had fewer 30-day complications, time to re-intervention within 12 months was decreased for SWL and PCNL, SWL and PCNL were correlated with a higher number of sick leave days, and SWL and particularly PCNL were associated with higher costs. SWL outpatients had fewer complications, re-interventions and lower costs than inpatients. This study was limited by the available information in claims data. CONCLUSION: URS cases showed benefits in terms of fewer re-interventions, fewer sick leave days, and lower healthcare costs. Only regarding complications, SWL was superior. This emphasizes URS as the most frequent treatment choice. Furthermore, SWL outpatients showed less costs, fewer complications, and re-interventions than inpatients.

Health-economic evaluation of collaborative orthogeriatric care for patients with a hip fracture in Germany: a retrospective cohort study using health and long-term care insurance claims data.

BACKGROUND: Evidence suggests benefits of orthogeriatric co-management (OGCM) for hip fracture patients. Yet, evidence on cost-effectiveness is limited and based on small datasets. The aim of our study was to conduct an economic evaluation of the German OGCM for geriatric hip fracture patients. METHODS: This retrospective cohort study was based on German health and long-term care insurance data. Individuals were 80 years and older, sustained a hip fracture in 2014, and were treated in hospitals providing OGCM (OGCM group) or standard care (control group). Health care costs from payer and societal perspective, life years gained (LYG) and cost-effectiveness were investigated within 1 year. We applied weighted gamma and two-part models, and entropy balancing to account for the lack of randomisation. We calculated incremental cost-effectiveness ratios (ICER) and employed the net-benefit approach to construct cost-effectiveness acceptability curves. RESULTS: 14,005 patients were treated in OGCM, and 10,512 in standard care hospitals. Total average health care costs per patient were higher in the OGCM group: €1181.53 (p < 0.001) from payer perspective, and €1408.21 (p < 0.001) from societal perspective. The ICER equalled €52,378.12/ LYG from payer and €75,703.44/ LYG from societal perspective. The probability for cost-effectiveness would be 95% if the willingness-to-pay was higher than €82,000/ LYG from payer, and €95,000/ LYG from societal perspective. CONCLUSION: Survival improved in hospitals providing OGCM. Costs were found to increase, driven by inpatient and long-term care. The cost-effectiveness depends on the willingness-to-pay. The ICER is likely to improve with a longer follow-up.

Local Recurrence Rates of Skin Tumors After Resection With Complete Circumferential Peripheral and Deep Margin Assessment-Identification of High-Risk Entities.

BACKGROUND: The local recurrence rates of malignant skin tumors after micrographic controlled surgery using complete circumferential peripheral and deep margin assessment (CCPDMA) are reported to be low. However, in daily practice, tumor entities with a significantly higher recurrence rate are found. OBJECTIVE: The aim of the investigation was to identify these high-risk tumors to develop approaches for risk stratification. PATIENTS AND METHODS: We included different malignant tumors that were surgically treated and examined with CCPDMA using paraffin sections and H&E staining. Re-excisions were performed until the tumor was completely removed. RESULTS: Ninety-nine thousand three hundred seventy-two tumors were included in the study; the follow-up period was 4 years (median). Eight tumor entities were identified as high-risk entities, showing a significantly higher local recurrence rate of over 20%: desmoplastic squamous cell carcinoma, desmoplastic melanoma, Merkel cell carcinoma, microcystic adnexal carcinoma, pleomorphic sarcoma, liposarcoma as well as angiosarcoma, and extramammary Paget's disease. CONCLUSION: Complete circumferential peripheral and deep margin assessment allows complete control of the resection margins and enables skin-sparing resections with low recurrence rates for basal cell carcinomas, nondesmoplastic squamous cell carcinomas, lentiginous melanomas, and dermatofibrosarcoma protuberans. However, other tumors show significantly higher recurrence rates and therefore need to be classified as high-risk tumors.

Regional variation of care dependency after hip fracture in Germany: A retrospective cohort study using health insurance claims data.

OBJECTIVE: To investigate variation of care dependency after hip fracture across German regions based on the assessment by the German statutory long-term care insurance. DATA SOURCES/STUDY SETTING: Patient-level statutory health and long-term care insurance claims data from 2009-2011 and official statistical data from Germany. STUDY DESIGN: We performed a retrospective cohort study. Investigated multinomial outcome categories were increase in care dependency (new onset or a higher care dependency than pre-fracture), no change as reference and death as competing risk in the quarterly period following hip fracture (follow-up 3 months). Regional variation was operationalized with the variance of regional-level random intercepts based on generalized linear mixed models. We adjusted for patient and regional characteristics. PRINCIPAL FINDINGS: The study included 122,887 hip fracture patients in 95 German postal code regions. Crude outcomes were 30.87% increase in care dependency and 14.35% death. Results indicated modest variation on regional level. Male sex, increasing age, increasing comorbidity, pertrochanteric and subtrochanteric fracture site compared to femoral neck, time from hospital admission to surgery of 3 or more days, as well as increasing inpatient length of stay, non-participation in rehabilitation and regions with lower hospital density were positively associated with an increase in care dependency. CONCLUSIONS: Several characteristics on patient and regional level associated with the outcome were identified. Variation in the increase in care dependency after hip fracture appeared to be attributable primarily to patient characteristics. Variation on regional level was only modest.

Uptake of an exercise class and use of bone density measurement after advice by the health insurance fund: results from the osteoporotic fracture prevention program in rural areas (OFRA).

BACKGROUND: OFRA is a large health insurance fund-driven program which aims to reduce the risk of falls and fractures in older people living in rural areas. The programme offered specific mobility and falls prevention classes and bone density measurement by a DXA scan free of charge to more than 10,000 people, and was promoted by staff of the health insurance fund either by a visit at home, or a phone call, or a visit at home and a subsequent phone call. The aim of this study was to analyse the uptake of an exercise class and the use of a DXA scan after advice. METHODS: Telephone interviews were conducted in a randomly selected subgroup of 780 persons 9 months after first contact. Rates of uptake of an exercise class or use of a DXA scan were calculated. Predictors of uptake and use were analysed applying logistic regression models. RESULTS: The rate of uptake after advice for specific mobility and fall prevention class was 29.6%. For DXA scan, the rate of use after advice was 16.7%. Rates of uptake and use increased if the first contact by a visit at home or a phone call was followed by an additional subsequent phone call. CONCLUSION: A direct motivational approach in older people by a health insurance fund is feasible and results in relevant participation and utilization rates in exercise classes and DXA scans.

Patient Characteristics as Indicator for Care Dependence after Hip Fracture: A Retrospective Cohort Study Using Health Insurance Claims Data From Germany.

OBJECTIVES: Hip fractures are common consequences of falls in older adults and, among other negative health outcomes, often lead to care dependence in the long term. Until 2016, the German long-term care insurance classified care recipients according to a standardized classification system consisting of 3 care levels. It was based on required assistance in performing activities of daily living and assessed by a qualified physician or nurse. Thus, care level reflects the degree of care dependence. The aim of this study was to determine relevant patient characteristics, which are related to the likelihood of increasing care dependence in terms of worsening care level after hip fracture. DESIGN: Retrospective cohort study. SETTING AND PARTICIPANTS: Statutory health insurance claims data including 122,922 insured individuals living in Germany and aged 65 years or older, who sustained a hip fracture from 2009 through 2011. MEASURES: The association of patient characteristics with worsening care level in the quarterly period after hip fracture was investigated by means of multinomial logit regression analysis. Death constitutes a competing risk and was modeled as additional nominal outcome. RESULTS: Among all patients, crude rates were 30.9% for worsening care level, 54.8% for unchanged care level, and 14.4% for death after hip fracture. The multivariate analysis revealed that patient factors male sex, increasing age, increasing comorbidity, increasing inpatient length of stay, and a lack of inpatient rehabilitation were significantly associated with a worsening care level. CONCLUSIONS/IMPLICATIONS: This study uses the German standardized measurement of care dependence in terms of worsening care level after hip fracture and finds various related patient characteristics. Knowledge of these characteristics helps to identify possible risk groups for care dependence after hip fracture, for which special attention can be provided regarding treatment and prevention of hip fractures.

Long-Term Effectiveness of a Multifactorial Fall and Fracture Prevention Program in Bavarian Nursing Homes: An Analysis Based on Health Insurance Claims Data.

OBJECTIVE: Femoral fractures are frequently consequences of falls in nursing homes and are associated with considerable costs and unfavorable outcomes such as immobility and mortality. The purpose of this study was to examine the long-term effectiveness of a multifactorial fall and fracture prevention program in nursing homes in terms of reducing femoral fractures. DESIGN: Retrospective cohort study. SETTING: Nursing homes. PARTICIPANTS: Health insurance claims data for 2005-2013 including 85,148 insurants of a sickness fund (Allgemeine Ortskrankenkasse Bayern), aged 65 years or older and living in 802 nursing homes in Bavaria, Germany. INTERVENTION: The fall prevention program was implemented stepwise in 4 time-lagged waves in almost 1,000 nursing homes in Bavaria, Germany, and was financially supported by a Bavarian statutory health insurance for the initial period of 3 years after implementation. The components of Bavarian Fall and Fracture Prevention Program were related to the staff (education), to the residents (progressive strength and balance training, medication, hip protectors), and suggested environmental adaptations as well as fall documentation and feedback on fall statistics. MEASUREMENTS: Data were used to create an unbalanced panel data set with observations per resident and quarterly period. We designed each wave to have 9 quarters (2.25 years) before implementation and 15 quarters (3.75 years) as follow-up period, respectively. Time trend-adjusted logistic generalized estimating equations were used to examine the impact of implementation of the fall prevention program on the likelihood of femoral fractures, controlling for resident and nursing home characteristics. The analysis took into account that the fall prevention program was implemented in 4 time-lagged waves. RESULTS: The implementation of the fall prevention program was not associated with a significant reduction in femoral fractures. Only a transient reduction of femoral fractures in the first wave was observed. Patient characteristics were positively associated with the likelihood of femoral fractures (P < .001); women compared to men [odds ratio (OR) = 0.877], age category 2 (OR = 1.486) and 3 (OR = 1.973) compared to category 1, care level 1 compared to 2 (OR = 0.897) and 3 (OR = 0.426), and a prior fracture (OR = 2.230) significantly increased the likelihood of a femoral fracture. CONCLUSIONS: There was no evidence for the long-term effectiveness of the fall prevention program in nursing homes. The restriction of the transient reduction to the first implementation wave may be explainable by a higher motivation of nursing homes starting first with the fall prevention program. Efforts should be directed to further identify factors that determine the long-term effectiveness of fall prevention programs in nursing homes.

The occurrence of polycyclic aromatic hydrocarbons in Peking duck: Relevance to food safety assessment.

Peking duck is one of the most well-known Chinese dishes. GC-MS analysis revealed that, either benzo(a)pyrene alone, or the total amount of major PAHs with carcinogenic potential for humans, reached levels of 8.7 and 54.7µg/kg, respectively. These levels greatly exceeded those found in grilled poultry in European countries. However, the intake of benzo(a)pyrene from a Peking duck meal (about 0.65µg) was not higher than that from the daily intake (for residents in the same area) from vegetables alone (about 2µg/day). Since Peking duck is still not a plebeian meat in this country, people would not consume it very often.
