Cost evaluation of an innovative outreach clinic across social insurance codes in rural Northern Germany - A routine data analysis.

A community outreach clinic was established in 2013 in a rural part of Germany to counsel and better integrate patients with mental health disorders or clients with psychosocial problems into the healthcare and complementary social assistance system. In a pilot study, we aimed to evaluate the costs of the integration assistance system after the outreach clinic was opened, the number of visits and the trend in the costs of the social assistance system of the federal state. Anonymised secondary cost data were used to evaluate the costs associated with the integration assistance receivers before (2010-2012) and after the establishment of the outreach clinic (2013-2015). Total costs were descriptively compared between the intervention group (consultation in the outreach clinic), the non-referral group, and a propensity score-matched control group for the years 2013-2015. To monitor the counselling activity, we used anonymised data on visits to the outreach clinic between 2013 and 2015. Data from 50 clients in the outreach clinic and 678 non-referral clients were analysed. The total costs of the integration assistance for the years 2013-2015 amounted to EUR 21,516 (95% CI 14,513-28,518) and EUR 28,464 (25,789-31,140) respectively. Propensity score matching of the controls resulted in equalised total costs for the years 2013 through 2015 for clients (n = 50, EUR 21,516 (14,513-28,518)) and controls (n = 250, EUR 21,725 (18,214-25,234)). The total number of integration assistance receivers in the district was lower than the average for the federal state. The number of consultations at the outpatient clinic steadily increased from 146 in 2013 to 1,090 in 2015. Counselling in the outreach clinic might help reduce the placement of clients into integration assistance, including supported housing, and slow the expected cost trend. However, counselling failed to lower total costs in the integration assistance service, possibly due to the selection of more severe cases.

[Descriptive Analysis of Health Economics of Intensive Home Care of Ventilated Patients]. / Gesundheitsökonomische deskriptive Analyse der häuslichen Intensivversorgung beatmeter Patienten.

INTRODUCTION: Long-term ventilated patients in Germany receive intensive care mainly in the patients' home or in assisted-living facilities. There is a lack of knowledge about the nature and extent of resource use and costs associated with care of this small, heterogeneous but overall growing patient group. METHODS: A sub-study in the context of a research project SHAPE analyzed costs of 29 patients descriptively from a social perspective. Direct and indirect costs of intensive home care over a period of three months were recorded and analyzed retrospectively. Standardized recorded written self-reports from patients and relatives as well as information from the interviewing of nursing staff and from nursing documentation were the basis for this analysis. RESULTS: There was an average total cost of intensive home care for three months per patient of 61194 € (95% CI 53 884-68 504) including hospital stays. The main costs were directly linked to outpatient medical and nursing care provided according to the Code of Social Law V and XI. Services provided by nursing home care service according to § 37(2) Code of Social Law V (65%) were the largest cost item. Approximately 13% of the total costs were attributable to indirect costs. CONCLUSIONS: Intensive home care for ventilated patients is resource-intensive and cost-intensive and has received little attention also from a health economics perspective. Valid information and transparency about the cost structures are required for an effective and economic design and management of the long-term care of this patient group.

A retrospective cost-analysis of additional homeopathic treatment in Germany: Long-term economic outcomes.

OBJECTIVES: This study aimed to provide a long-term cost comparison of patients using additional homeopathic treatment (homeopathy group) with patients using usual care (control group) over an observation period of 33 months. METHODS: Health claims data from a large statutory health insurance company were analysed from both the societal perspective (primary outcome) and from the statutory health insurance perspective (secondary outcome). To compare costs between patient groups, homeopathy and control patients were matched in a 1:1 ratio using propensity scores. Predictor variables for the propensity scores included health care costs and both medical and demographic variables. Health care costs were analysed using an analysis of covariance, adjusted for baseline costs, between groups both across diagnoses and for specific diagnoses over a period of 33 months. Specific diagnoses included depression, migraine, allergic rhinitis, asthma, atopic dermatitis, and headache. RESULTS: Data from 21,939 patients in the homeopathy group (67.4% females) and 21,861 patients in the control group (67.2% females) were analysed. Health care costs over the 33 months were 12,414 EUR [95% CI 12,022-12,805] in the homeopathy group and 10,428 EUR [95% CI 10,036-10,820] in the control group (p<0.0001). The largest cost differences were attributed to productivity losses (homeopathy: EUR 6,289 [6,118-6,460]; control: EUR 5,498 [5,326-5,670], p<0.0001) and outpatient costs (homeopathy: EUR 1,794 [1,770-1,818]; control: EUR 1,438 [1,414-1,462], p<0.0001). Although the costs of the two groups converged over time, cost differences remained over the full 33 months. For all diagnoses, homeopathy patients generated higher costs than control patients. CONCLUSION: The analysis showed that even when following-up over 33 months, there were still cost differences between groups, with higher costs in the homeopathy group.

Frequency and clinical relevance of potential cytochrome P450 drug interactions in a psychiatric patient population - an analysis based on German insurance claims data.

BACKGROUND: Numerous drugs used in the treatment of psychiatric disorders are substrates of cytochrome P450 enzymes and are potential candidates for drug-drug interactions (DDIs). METHODS: Claims data of a German statutory health insurance company from severely mentally ill patients who registered in an integrated care contract from August 2004 to December 2009 were analysed. We measured time periods of concomitant prescription of drugs that have been reported to interact via cytochrome P450, with a focus on drugs acting as strong inhibitors. Such drug-drug exposure (DDE) is an incontrovertible precursor of DDIs. We assessed whether potential DDIs were considered clinically relevant based on the prescribing information of the respective drugs. RESULTS: Among all 1221 patients, 186 patients (15.2 %; Clopper-Pearson 95 % confidence interval (CI): 13.3-17.4 %) had at least one DDE prescription, and 58 patients (4.8 %; 95 % CI 3.6-6.1) had at least one DDE prescription involving a strong cytochrome P450 inhibitor. In 59 patients, (4.8 %; 95 % CI: 3.7-6.2 %) five or more DDEs were identified, and five or more DDEs with a strong inhibitor were identified in 18 patients (1.5 %; 95 % CI: 0.9-2.3). The rates of DDEs were 0.27 (Garwood 95%CI: 0.25-0.28) per person-year and 0.07 (95 % CI: 0.07-0.08) for strong-inhibitor DDEs. Four of the ten most frequent DDEs were identified as clinically relevant, and seven of the eight most frequent DDEs involving a strong inhibitor were clinically relevant. CONCLUSIONS: The number of patients with DDEs was not alarmingly high in our sample. Nevertheless, prescription information showed that some prescribed drug combinations could result in serious adverse consequences that are known to weaken or strengthen the effect of the drugs and should therefore be avoided.

Can Additional Homeopathic Treatment Save Costs? A Retrospective Cost-Analysis Based on 44500 Insured Persons.

OBJECTIVES: The aim of this study was to compare the health care costs for patients using additional homeopathic treatment (homeopathy group) with the costs for those receiving usual care (control group). METHODS: Cost data provided by a large German statutory health insurance company were retrospectively analysed from the societal perspective (primary outcome) and from the statutory health insurance perspective. Patients in both groups were matched using a propensity score matching procedure based on socio-demographic variables as well as costs, number of hospital stays and sick leave days in the previous 12 months. Total cumulative costs over 18 months were compared between the groups with an analysis of covariance (adjusted for baseline costs) across diagnoses and for six specific diagnoses (depression, migraine, allergic rhinitis, asthma, atopic dermatitis, and headache). RESULTS: Data from 44,550 patients (67.3% females) were available for analysis. From the societal perspective, total costs after 18 months were higher in the homeopathy group (adj. mean: EUR 7,207.72 [95% CI 7,001.14-7,414.29]) than in the control group (EUR 5,857.56 [5,650.98-6,064.13]; p<0.0001) with the largest differences between groups for productivity loss (homeopathy EUR 3,698.00 [3,586.48-3,809.53] vs. control EUR 3,092.84 [2,981.31-3,204.37]) and outpatient care costs (homeopathy EUR 1,088.25 [1,073.90-1,102.59] vs. control EUR 867.87 [853.52-882.21]). Group differences decreased over time. For all diagnoses, costs were higher in the homeopathy group than in the control group, although this difference was not always statistically significant. CONCLUSION: Compared with usual care, additional homeopathic treatment was associated with significantly higher costs. These analyses did not confirm previously observed cost savings resulting from the use of homeopathy in the health care system.

Influence of subcutaneous specific immunotherapy on drug costs in children suffering from allergic asthma.

BACKGROUND: Subcutaneous specific immunotherapy (SCIT) is an effective treatment attenuating the progression of allergic asthma. To date, there is a lack of studies investigating the economic consequences of SCIT on health care expenditures. METHODS: A health-economic piggy-back analysis of SCIT was conducted based on a RCT that enrolled 65 children and adolescents with allergic asthma. Patients were allocated into two groups: A group receiving SCIT with a high-dose hypoallergenic house dust mite preparation plus asthma medication and a control group receiving only asthma medication. For both groups asthma control was achieved before the start of the SCIT treatment and was maintained during the study. Both, costs and cost-effectiveness of SCIT with the high-dose hypoallergenic house dust mite preparation were investigated based on total medication costs, incremental medication costs and treatment effects (measured as lung function), respectively. A bootstrap analysis was performed to validate the results. RESULTS: A steady decline in medication costs could be observed in the SCIT group one year after treatment start compared to the control group. This cost trend became statistically significant 3 years after SCIT started. The calculated potential savings in the SCIT group correlated with an improved lung function. The distribution of the bootstrap results revealed that the probability of SCIT having a superior effectiveness compared to the control group is around 90%. CONCLUSION: SCIT with a high-dose hypoallergenic preparation received by children and adolescents suffering from mite induced allergic asthma reduces the allergic medication intake and has cost-saving effects. Additional costs associated with SCIT may be completely compensated by drug cost savings 4 years after end of SCIT. Additionally, SCIT is superior compared to routine care as measured by the lung function that improved in SCIT-treated patients. TRIAL REGISTRATION: (EudraCT no. 2004 - 003892 - 35).

Opinions on Kampo and reasons for using it--results from a cross-sectional survey in three Japanese clinics.

BACKGROUND: Traditional Japanese Medicine (Kampo) is often used in Japan, but very little data on its users are available. We investigated who uses Kampo, the reasons and opinions for its use. METHODS: Questionnaire survey in three Japanese outpatient clinics offering Kampo in different settings: Kampo only, Kampo and traditional Chinese medicine, Kampo and Western medicine. Before seeing the doctor, patients were asked about socio-demographic data, medical history, experience with Kampo, general health-related opinions and behaviours, opinions about Western medicine and Kampo, and reasons for Kampo utilization. Descriptive statistics and predictors for Kampo use were calculated. RESULTS: A total of 354 questionnaires were completed. Participants were 50.97 ± 15.60 (mean ± SD) years of age, 68% were female. Of all patients, 73% (n = 202) were using Kampo currently and 84% (297) had taken Kampo before. Questions on general health-related opinions and behaviour revealed a strong environmental awareness. The most frequent indications for earlier Kampo use were: common cold (36%), gastrointestinal complaints (30%), oversensitivity to cold ("Hi'e-sho"; 29%), stress/anxiety (21%), and shoulder stiffness (20%). Kampo users suffered more often from chronic illnesses (OR 2.88 [1.48-5.58]). Beliefs in underlying philosophy (Wu Xing (adjusted OR 3.08, [1.11-8.55]), Ying and Yang (OR 2.57 [1.15-5.73], a holistic way of seeing the patient (OR 2.17 [1.53-3.08]), and in Kampo efficacy (OR 2.62 [1.66-4.13]) were positively associated with Kampo use. So was, interestingly, conviction of the efficacy of Western medicine (OR 1.87 [1.28-2.74]). Half of the patients had a general preference for a combination of Kampo and Western treatment. CONCLUSIONS: Most patients visiting a clinic that also provided Kampo had previous experience with Kampo. Usage was associated with beliefs in philosophical Kampo concepts and its efficacy.

Posaconazole prophylaxis--impact on incidence of invasive fungal disease and antifungal treatment in haematological patients.

Since two large-scale, randomised studies on posaconazole prophylaxis have demonstrated a clear benefit for patients at high risk for contracting invasive fungal disease (IFD), posaconazole prophylaxis has been adopted as standard of care for this patient collective. Several years on from implementation at our institution, we wanted to evaluate its impact on the incidence and use of empirical antifungal therapy in a real-life setting. We analysed retrospectively incidence and severity of IFD in high-risk patients with prophylaxis, using a historical cohort as comparator. A total of 200 patients had either received the extended spectrum triazole posaconazole in prophylactic dosage of 200 mg tid or empirical antifungal therapy. Disease events were analysed by application of the revised EORTC/MSG definitions for IFD. Before posaconazole prophylaxis, we recorded 57/100 cases of IFD which was reduced to 28/100 with prophylaxis. The empirical use of antifungal drugs was reduced to 41% from 91% in the non-prophylaxis cohort. Furthermore, we observed a shift in the categorisation of IFD according to EORTC/MSG criteria. Our data suggest that posaconazole was effective in reducing the rate and probability of invasive fungal disease in high-risk patients.

The loudness dependence of auditory evoked potentials and effects of psychopathology and psychopharmacotherapy in psychiatric inpatients.

OBJECTIVE: Many studies have provided evidence for the loudness dependence of auditory evoked potentials (LDAEP) as a marker for central serotonergic activity but remained inconclusive for its suitability in clinical use. METHODS: A cross-sectional sample of 162 psychiatric inpatients (major depression N = 86, bipolar disorder N = 12, schizophrenia N = 50, and schizoaffective disorder N = 14) and 40 healthy subjects was retrospectively examined for LDAEP and effects of psychopathology and psychopharmacology. RESULTS: The LDAEP was weaker in patients with affective disorders than in healthy subjects but did not differentiate between the total patient sample and healthy controls. LDAEP correlated significantly with dimensions of the Brief Symptom Inventory in the total patient sample (depression, paranoid ideation, psychoticism, Global Symptom Index, and Positive Symptom Distress Index), in patients with affective disorders (depression) and with schizophrenia spectrum disorders (depression, psychoticism, Global Symptom Index, and Positive Symptom Distress Index). Similar correlations were found in depressed patients with a single noradrenergic and specific serotonergic antidepressant or serotonin-norepinephrine reuptake inhibitor. There was a negative correlation between dosage of typical antipsychotics and LDAEP. Hypnotics generally led to a lower LDAEP. CONCLUSION: The LDAEP in patients is related to severity of psychopathologic syndromes irrespective of diagnosis. Chronic psychopharmacologic treatment may also differentially modulate the LDAEP, but longitudinal studies are needed.
