Effectiveness of a peer-supported crisis intervention to reduce the proportion of compulsory admissions in acute psychiatric crisis interventions in an outreach and outpatient setting: study protocol for an exploratory cluster randomised trial combined with qualitative methods.

INTRODUCTION: Compulsory admissions are associated with feelings of fear, humiliation and powerlessness. The number of compulsory admissions in Germany and other high-income countries has increased in recent years. Peer support has been shown to increase the self-efficacy of individuals with mental health conditions in acute crises and to reduce the use of coercive measures in clinical settings. The objective of this study is to reduce the number of compulsory admissions by involving peer support workers (PSWs) in acute mental health crises in outreach and outpatient settings. METHODS AND ANALYSIS: This one-year intervention is an exploratory, cluster randomised study. Trained PSWs will join the public crisis intervention services (CIS) in two of five regions (the intervention regions) in the city of Bremen (Germany). PSWs will participate in crisis interventions and aspects of the mental health services. They will be involved in developing and conducting an antistigma training for police officers. The remaining three regions will serve as control regions. All individuals aged 18 and older who experience an acute mental health crisis during the operating hours of the regional CIS in the city of Bremen (around 2000 in previous years) will be included in the study. Semistructured interviews will be conducted with PSWs, 30 patients from control and intervention regions, as well as two focus group discussions with CIS staff. A descriptive comparison between all participants in the intervention and control regions will assess the proportion of compulsory admissions in crisis interventions during the baseline and intervention years, including an analysis of temporal changes. ETHICS AND DISSEMINATION: This study was approved by the Ethics Committee of the University of Bremen (file 2022-09) on 20 June 2022. The results will be presented via scientific conferences, scientific journals and communicated to policy-makers and practitioners. TRIAL REGISTRATION NUMBER: DRKS00029377.

[Medical care with or without cooperative agreements? A cross-sectional study in nursing homes in Bremen and Lower Saxony]. / Ärztliche Versorgung mit oder ohne Kooperationsvertrag? Eine Querschnittsuntersuchung in stationären Pflegeeinrichtungen in Bremen und Niedersachsen.

BACKGROUND: Empirical studies in nursing homes show that people in need of long-term care have less contact with medical specialists (except for neurologists) compared to those of the same age who are not in need of long-term care, which can be an indication of insufficient health care provision. Against this background, a cooperative agreement between medical specialists and nursing homes was first made legally possible, then requested and finally made mandatory (section 119b SGB V [Social Code Book V] in the currently valid version). OBJECTIVE: The aim of this study is to investigate to what extent contact density to physicians and the needs-based medical treatment of nursing home residents in nursing homes with and without a cooperative agreement differ from each other and, hence, how effective such cooperation agreements are in this context. METHODOLOGY: Using data from 396 people in need of care from 44 nursing homes in Lower Saxony and Bremen we compared facilities with and without cooperative agreements with respect to the number of home visits, practice visits and telephone contacts and the realization of adequate specialist medical treatment. At the time of the survey, 26 of the 44 nursing homes had cooperative agreements with dentists, 17 with general practitioners and 7 with neurologists. RESULTS: The number of personal contacts to general practitioners tends to be higher if cooperation agreements between general practitioners and nursing homes exist. In nursing homes having cooperation agreements with dentists the number of home visits is twice as high as in nursing homes without such an agreement, whereas cooperation agreements with neurologists have no effect on the number of contacts with these specialists. Furthermore, cooperation agreements with dentists promote appropriate dental care. CONCLUSIONS: The results show that cooperation agreements can be a useful instrument to ensure medical care in nursing homes. To guarantee the effectiveness of the cooperation agreements, however, the number of medical visits should be stipulated in the agreements.

Analyses of Basal and Squamous Cell Carcinoma Reported as an Adverse Drug Reaction and Comparison with Cases from the Cancer Registry from Germany.

INTRODUCTION: In Germany, incidence rates of basal cell (BCC) and squamous cell carcinoma (SCC) rose significantly from 1998 to 2010. Ultraviolet (UV) light exposure, immunosuppressants and drugs with photosensitising potential are known to increase the risk to develop BCC and SCC. The aim of our study was to analyse the adverse drug reaction (ADR) reports from Germany referring to BCC and SCC and to compare them to BCC and SCC occurring in the general population. METHODS: We analysed all validated spontaneous ADR reports referring to BCC (n = 191) and SCC (n = 75) from Germany contained in the European ADR database EudraVigilance prior to 6 March 2019. These reports were compared to 1,267,210 BCC and 476,903 SCC cases from the German Centre for Cancer Registry Data recorded from 2006 to 2018. RESULTS: The number of BCC and SCC reports as well as the BCC and SCC incidences in the registry increased in the analysed time period. Patients with drug-associated BCC (60 years) and SCC (64 years) were younger than patients with BCC (72 years) and SCC (76 years) in the registry. In 57.1 and 60.0% of BCC and SCC reports immunosuppressants were reported as suspected. The reported suspected drug was assumed to possess a photosensitising potential in 41.9 and 44.0% of BCC and SCC reports. CONCLUSIONS: In Germany, drug-associated BCC and SCC occurred at a younger age than in the general population. The results underline the necessity for skin cancer screening of patients treated with immunosuppressants or with drugs with photosensitising potential.

Promoting rational antibiotic therapy among high antibiotic prescribers in German primary care-study protocol of the ElektRA 4-arm cluster-randomized controlled trial.

BACKGROUND: The rational use of antibiotics is of great importance in health care. In primary care, acute respiratory infections are the most common cause of inappropriate antibiotic prescribing. Since existing studies aiming to optimize antibiotic use are usually based on the voluntary participation of physicians, general practitioners (GPs) with inappropriate prescribing behavior are underrepresented. For the first time in Germany, the ElektRA study will assess and compare the effects of three interventions on antibiotic prescribing rates for respiratory and urinary tract infections among high prescribers in primary care. METHOD: ElektRA is a 4-arm cluster-randomized controlled trial among German GPs in nine regional Associations of Statutory Health Insurance Physicians. On their behalf, the Central Research Institute of Ambulatory Health Care in Germany (Zi) analyses all outpatient claims and prescription data. Based on this database, high antibiotic prescribing GPs are identified and randomized into four groups: a control group (N=2000) and three intervention arms. We test social norm feedback on antibiotic prescribing (N=2000), social norm feedback plus online training on rational prescribing practice and communication strategies (N=2000), and social norm feedback plus online peer-moderated training on rational antibiotic prescribing, communication strategies, and sustainable behavior change (N=1250). The primary outcome is the overall rate of antibiotic prescriptions. Outcomes are measured before intervention (T0, October 2020-September 2022) and over a period of 15 months (T1, October 2022 to December 2023) after randomization. DISCUSSION: The aim of the study is to implement individualized, low-threshold interventions to reduce antibiotic prescribing among high prescribers in primary care. If successful, a change in behavior among otherwise difficult-to-reach high prescribers will directly improve patient care. The increase in quality of care will ideally be achieved both in terms of the quantity of antibiotics used as well as the kind of substances prescribed. Also, if effective strategies for high prescribers are identified through this study, they can be applied not only to the antibiotics addressed in this study, but also to other areas of prescription management. TRIAL REGISTRATION: Current Controlled Trials ISRCTN95468513.

[Home Treatment "Bremen ambulant vor Ort (BravO)"]. / Die aufsuchende Behandlung "Bremen ambulant vor Ort (BravO)".

OBJECTIVE: The existing legal framework to foster home treatment for severe mental illness imposes challenges for implementation. 'Bremen ambulant vor Ort (BravO)' provides home treatment on basis of the "Bundespflegesatzverordnung". METHODS: The concept and framework of BravO will be outlined, routine data on the BravO treatment from October 1st, 2019 to September 30th, 2021 were analysed. RESULTS: Financial and staff resources of 20 in-patient treatment places were equivalently transferred into BravO. 298 patients generating 392 cases received treatment. Median treatment span was 36 days, with 21 days (median) of service delivery. 74.7 % were diagnosed either in ICD-10 groups F2 or F3. CONCLUSION: BravO was successfully implemented into routine care. BravO allows flexible home treatment for people with severe mental illness apart from existing treatment framework.

Descriptive analysis of adverse drug reaction reports for hypersensitivity reactions stratified in relation to different beta-lactam antibiotics.

ß-lactam antibiotics (BLA) are commonly reported to induce hypersensitivity reactions. However, ß-lactam antibiotic-stratified analyses are rare. In the presented study, ß-lactam antibiotic associated hypersensitivity reactions were analyzed in the European adverse drug reaction (ADR) database. 923, 38, 222, and 99 hypersensitivity reports for penicillins and first-, second- and third-generation cephalosporins were reported. Differences with regard to demographical parameters, seriousness and types of hypersensitivity reactions, as well as in the number of hypersensitivity reports per outpatient prescriptions were observed between the different ß-lactam antibiotics. The number of ADR reports classified as serious was higher for all generations of cephalosporins compared to penicillins. Additionally, anaphylactic reactions were more often reported for first- and second-generation cephalosporins compared to third-generation cephalosporins and penicillins, while bullous reactions were more often reported for first- and third-generation cephalosporins as opposed to second-generation cephalosporins and penicillins. The observed differences may be caused by differences between ß-lactam antibiotics and their routes of administration (oral, intravenous), the patient populations, or the reporting of ADRs. Due to the methodological limitations of ADR database analysis, no conclusions can be drawn whether and to what extent the aforementioned factors influenced our results.

Descriptive analysis of 179 German reports of melanoma reported to an adverse drug reaction database as a drug-related adverse effect, and comparison with melanoma cases contained in German cancer registries.

BACKGROUND: Malignant melanoma (MM) is one of the most aggressive forms of skin cancer. The occurrence of MM associated with drug therapy has been described in the literature. However, there is no analysis of a substantial number of validated reports of drug-associated MM. AIM: To analyse a substantial number of validated spontaneous reports of drug-associated MM with regard to the suspected drug and the reported characteristics, and to compare these analyses with those of MM cases occurring in the general population in Germany. METHODS: Spontaneous reports of MM associated with drug therapy in Germany were identified in a large adverse drug reaction database (EudraVigilance). These results were then compared with analyses of MMs in the pooled data from a population-based German cancer registry. RESULTS: The 10 most frequently suspected drugs in the MM reports all target the immune system, with 7 of these being immunosuppressants. The median time to onset to MM diagnosis was 2.0 years. Patients with drug-associated MM were 11 years (median) younger than patients with MM in the cancer registry, and this age difference was greater for female than for male patients. CONCLUSIONS: Our results emphasize the importance of regular dermatological examinations of patients being treated with immunosuppressants. Physicians should be aware that in these patients, MM might be detected at younger ages and even within 2 years after initiating therapy.

Contacts with general practitioners, dentists, and medical specialists among nursing home residents: a cross-sectional study in 44 German nursing homes.

BACKGROUND: Nursing home residents have high medical care needs. Their medical care utilization is, however, lower compared to community-dwelling elderly and varies widely among nursing homes. This study quantified the utilization of general practitioners (GPs), dentists, and medical specialists among nursing homes and residents, and investigated whether dentist utilization is associated with individual and nursing home characteristics. METHODS: Forty-four nursing homes invited 2124 residents to participate in a cross-sectional study. For 10 medical specialties, data on contacts in nursing homes, practices, and by telephone in the last 12 months were assessed at individual and nursing home level. The proportion of nursing homes and residents with any form of contact, and the median number and interquartile range (IQR) of contacts among individuals with contact were determined. Using multilevel logistic regression, associations between the probability of individual dental care utilization and sex, age, LTC grade, years of residence, sponsorship, number of nursing home beds, and transport and medical escort services for consultations at a practice were investigated. RESULTS: The proportion of nursing homes with any form of contact with physicians ranged from 100% for GPs, dentists, and urologists to 76.7% for gynecologists and orthopedists. Among the nursing homes, 442 residents participated (20.8% response). The proportion of residents with any contact varied from 97.8% for GPs, 38.5% for neurologists/psychiatrists, and 32.3% for dentists to 3.0% for gynecologists. Only for GPs, neurologists/psychiatrists, dentists, otorhinolaryngologists, urologists, and dermatologists, the proportion was higher for nursing home contacts than for practice and telephone contacts. Among residents with any contact, the median number of contacts was highest for GPs (11.0 [IQR 7.0-16.0]), urologists (4.0 [IQR 2.0-7.0]), and neurologists/psychiatrists (3.0 [IQR 2.0-5.0]). Dentist utilization varied widely among nursing homes (median odds ratio 2.5) and was associated with higher age. CONCLUSIONS: Almost all residents had regular contact to GPs, but only one third had contact with dentists. Lower proportions with contact were found for medical specialists, except for neurologists/psychiatrists. Reasons for the large variations in dental care utilization among nursing homes should be identified. TRIAL REGISTRATION: DRKS00012383 [2017/12/06].

Reemergence of Scabies Driven by Adolescents and Young Adults, Germany, 2009-2018.

To validate anecdotal evidence on scabies infestations, we analyzed inpatient and outpatient claims data in Germany. Scabies diagnoses increased 9-fold and treatment failure 4-fold during 2009-2018, driven mainly by persons 15-24 years of age. Prevention and control in young adults appear key because of these persons' high mobility and social connectivity.

[Medical specialist undertreatment in nursing home residents-Prevalence and extrapolation]. / Fachärztliche Unterversorgung bei Heimbewohnern ­ Prävalenzstudie und Hochrechnung.

BACKGROUND: Nursing home residents tend to have lower medical specialist utilization than other groups of older people; however, as yet there is little evidence whether nursing home residents obtain adequate medical specialist care. This study investigated whether nursing home residents receive adequate oral health care, ophthalmological care, otorhinolaryngologist care and neurological care. The unmet needs of the nursing home population in Germany was extrapolated. MATERIAL AND METHODS: Audiometry, eye examinations and oral visual inspection were performed in 409 residents from 44 nursing homes. Medical care in the previous 12 months as well as existing diagnoses were retrieved from the nursing documentation. Teams of physicians evaluated for each resident based on all collected data if the resident obtained specialist care that was adequate to the needs. RESULTS: Between 15% and 45% of the residents with need for medical specialist care did not receive adequate specialist care. Of all residents 27% had unmet need of specialist care in at least one of the investigated medical specialties. It is projected that up to 205,000 nursing home residents in Germany do not receive adequate medical specialist care. CONCLUSION: Given a considerable proportion of nursing home residents with unmet need of specialist care, interventions should be developed that help reduce the level of unmet needs.

Analysis of the reporting of adverse drug reactions in children and adolescents in Germany in the time period from 2000 to 2019.

The objective of this study was to analyse reports on adverse drug reactions (ADRs) from Germany in the particularly vulnerable patient group of children and adolescents. Reporting characteristics, demographic parameters and off-label use were examined among others. The ratio of ADR reports per number of German inhabitants and the ratio of ADR reports per number of German inhabitants exposed to drugs were calculated and compared. These parameters were examined to derive trends in reporting of ADRs. 20,854 spontaneous ADR reports for the age group 0-17 years were identified in the European ADR database EudraVigilance for the time period 01.01.2000-28.02.2019 and analysed with regard to the aforementioned criteria. 86.5% (18,036/20,854) of the ADR reports originated from Healthcare Professionals and 12.2% (2,546/20,854) from non-Healthcare Professionals. 74.4% (15,522/20,854) of the ADR reports were classified as serious. The proportion of ADR reports per age group was 11.8% (0-1 month), 11.0% (2 months-1 year), 7.4% (2-3 years), 9.3% (4-6 years), 25.8% (7-12 years), and 34.8% (13-17 years) years, respectively. Male sex slightly dominated (51.2% vs. 44.8% females). Only 3.5% of the ADR reports reported off-label use. The annual number of ADR reports increased since 2000, even if set in context with the number of inhabitants and assumed drug-exposed inhabitants. The pediatric population declined in the study period which argues against its prominent role for the increase in the total number of ADR reports. Instead, among others, changes in reporting obligations may apply. The high proportion of serious ADR reports underlines the importance of pediatric drug safety.

The Decline in Outpatient Antibiotic Use.

BACKGROUND: A central component of the German antibiotic resistance strategy is to monitor the outpatient prescribing of systemic antibiotics nationwide, across all of the statutory health-insurance providers, in order to provide a basis for targeted quality-assurance measures. METHODS: All outpatient drug prescription data from patients covered by the statutory health-insurance carriers in Germany in the age groups 0-14, 15-64, and ≥ 65 years were assessed. The chosen primary outcome measure under study was the prescription rate (number of antibiotic prescriptions per 1000 insurees per year) for the years 2010 to 2018. RESULTS: Over the period of the study, a 21% decline was seen in the use of systemic antibiotics in outpatients, from 562 to 446 prescriptions per 1000 insurees per year in 2010 and 2018, respectively. The most marked reduction in the prescription rate-by 41%-was seen among child and adolescent insurees (in other age groups: -17% among those aged 15-64, -12% among those aged 65 and older). A downward trend was seen in all regions of Germany, and for most of the active substance groups for which data were obtained. In 2018, the prescription rate varied by a factor of 1.8 among regions, with the highest rate in the Saarland (572 per 1000 insurees per year) and the lowest in Brandenburg (318 per 1000 insurees per year). CONCLUSION: The observed nationwide decline in the prescription of antibiotics to outpatients in all age groups may be a result of the numerous initiatives that have been put into action to reinforce the appropriate use of antibiotics in Germany. A change in pediatric prescribing practices is demonstrated by the marked reduction in this age group. The remaining major differences across German regions underscore the importance of regionally tailored programs for the promotion of rational antibiotic use.

Optimizing Antibiotic Prescribing for Acute Respiratory Tract Infection in German Primary Care: Study Protocol for Evaluation of the RESIST Program.

BACKGROUND: The emergence and increased spread of microbial resistance is a major challenge to all health care systems worldwide. In primary care, acute respiratory tract infection (ARTI) is the health condition most strongly related to antibiotic overuse. OBJECTIVE: The RESIST program aims at optimizing antibiotic prescribing for ARTI in German primary care. By completing a problem-orientated online training course, physicians are motivated and empowered to utilize patient-centered doctor-patient communication strategies, including shared decision making, in the treatment of patients with ARTI. METHODS: RESIST will be evaluated in the form of a nonrandomized controlled trial. Approximately 3000 physicians of 8 (out of 16) German federal states can participate in the program. Patient and physician data are retrieved from routine health care data. Physicians not participating in the program serve as controls, either among the 8 participating regional Associations of Statutory Health Insurance Physicians (control group 1) or among the remaining associations not participating in RESIST (control group 2). Antibiotic prescription rates before the intervention (T0: 2016, 1st and 2nd quarters of 2017) and after the intervention (T1: 3rd quarter of 2017 until 1st quarter of 2019) will be compared. The primary outcome measure is the overall antibiotic prescription rate for all patients insured with German statutory health insurance before and after provision of the online course. The secondary outcome is the antibiotic prescription rate for coded ARTI before and after the intervention. RESULTS: RESIST is publicly funded by the Innovations funds of the Federal Joint Committee in Germany and was approved in December 2016. Recruitment of physicians is now completed, and a total of 2460 physicians participated in the intervention. Data analysis started in February 2020. CONCLUSIONS: With approximately 3000 physicians participating in the program, RESIST is among the largest real-world interventions aiming at reducing inadequate antibiotic prescribing for ARTI in primary care. Long-term follow up of up to 21 months will allow for investigating the sustainability of the intervention. TRIAL REGISTRATION: ISRCTN Registry ISRCTN13934505; http://www.isrctn.com/ISRCTN13934505.

Comparing stroke prevention therapy of direct oral anticoagulants and vitamin K antagonists in patients with atrial fibrillation: a nationwide retrospective observational study.

BACKGROUND: Direct oral anticoagulants (DOACs) are not only increasingly being used for the initial stroke prevention therapy but progressively also substitute vitamin K antagonist (VKA) treatment in patients with non-valvular atrial fibrillation (AF). DOACs have been compared regarding therapeutic efficacy and adverse outcomes to warfarin in several pivotal studies and showed non-inferiority in terms of stroke prevention and superiority in terms of bleeding complications. However, comprehensive comparative studies are lacking for phenprocoumon, a VKA prescribed frequently outside the USA and the UK and accounting for 99% of all VKA prescriptions in Germany. Patients treated with phenprocoumon seem to meet more often international normalized ratio values in the therapeutic range, which may have implications concerning their efficacy and safety. This study aims at comparing the risk of stroke and bleeding in phenprocoumon- and DOAC-treated patients with AF in an adequately powered observational study population. METHODS: Retrospective analysis of stroke and bleeding incidence of 837,430 patients (1.27 million patient years) treated with DOAC or phenprocoumon for stroke prevention in German ambulatory care between 2010 and 2017. Relative risks of stroke and bleeding were estimated by calculating cox regression-derived hazard ratios (HR) and 95% confidence intervals (CI) of propensity score-matched cohorts. RESULTS: Patients treated with DOAC had an overall higher risk for stroke (HR 1.32; CI 1.29-1.35) and a lower risk for bleeding (0.89; 0.88-0.90) compared to phenprocoumon. When analyzed separately, the risk for stroke was higher for dabigatran (1.93; 1.82-2.03), apixaban (1.52; 1.46-1.58), and rivaroxaban (1.13; 1.10-1.17) but not for edoxaban (0.88; 0.74-1.05). The risk for bleeding was lower for dabigatran (0.85; 0.83-0.88), apixaban (0.71; 0.70-0.73), and edoxaban (0.29; 0.17-0.51) but not for rivaroxaban (1.03; 1.01-1.04). CONCLUSIONS: This study provides a comprehensive view of the stroke and bleeding risks associated with phenprocoumon and DOAC use in Germany. Phenprocoumon may be preferable to DOAC treatment for the prevention of strokes in AF in a real-world population cared for in ambulatory care.

Marked reductions in outpatient antibiotic prescriptions for children and adolescents - a population-based study covering 83% of the paediatric population, Germany, 2010 to 2018.

BackgroundPrescribing of systemic antibiotics in general and of cephalosporins in particular in German paediatric outpatients has previously been reported to be higher than in other European countries.AimOur objective was to assess recent trends in antibiotic prescribing in German children.MethodsThis study was conducted as consecutive annual cross-sectional analyses and included all children aged 0-14 years (n = 9,389,183 in 2018) covered by statutory health insurance in Germany. Annual antibiotic prescription rates from 2010 to 2018 were calculated for the age groups 0-1, 2-5, 6-9 and 10-14 years. Poisson regression was used to estimate trends of prescription rates by age group and antibiotic subgroup.ResultsOverall, the age-standardised antibiotic prescription rate decreased significantly by 43% from 746 prescriptions per 1,000 persons in 2010 to 428 per 1,000 in 2018 (p < 0.001). Reductions were most pronounced in the age groups 0-1 year (-50%) and 2-5 years (-44%). The age group 2-5 years exhibited the highest prescription rate with 683 per 1,000 in 2018 (0-1 year: 320/1,000; 6-9 years: 417/1,000; 10-14 years: 273/1,000). Cephalosporins (second and third generation) accounted for 32% of prescribed antibiotics.ConclusionsMarked reductions in antibiotic prescribing during the last decade indicate a change towards more judicious paediatric prescribing habits. Compared with other European countries, however, prescribing of second- and third-generation cephalosporins remains high in Germany, suggesting frequent first-line use of these substances for common respiratory infections. Considerable regional variations underline the need for regionally targeted interventions.

Claims data analysis of medical specialist utilization among nursing home residents and community-dwelling older people.

BACKGROUND: Most older people, and especially those in need of long-term care, suffer from one or more chronic diseases. Consequently, older people have an increased need of medical care, including specialist care. There is little evidence as yet whether older people with greater medical care needs obtain adequate medical care because existing studies do not sufficiently control for differences in morbidity. In this study we investigate whether differences in medical specialist utilization exist between older people with and without assessed long-term care need in line with Book XI of the German Social Code, while at the same time controlling for individual differences in morbidity. METHODS: We used data from the 11 German AOK Statutory Health and Long-term Care Insurance funds of 100,000 members aged 60 years or over. Zero-inflated Poisson regression analyses were applied to investigate whether the need for long-term care and the long-term care setting are associated with the probability and number of specialist visits. We controlled for age, gender, morbidity and mortality, residential density, and general practitioner (GP) utilization. RESULTS: Older people in need of long-term care are more likely to have no specialist visit than people without the need for long-term care. This applies to nearly all medical specialties and for both care settings. Yet, despite these differences in utilization probability the number of specialist medical care visits between older people with and without the need for long-term care is similar. CONCLUSION: Older people in need of long-term care might face access barriers to specialist care. Once a contact is established, however, utilization does not differ considerably between those who need long-term care and those who don't; this indicates the importance of securing an initial contact.

Differences in medical specialist utilization among older people in need of long-term care - results from German health claims data.

BACKGROUND: Elderly in need of long-term care tend to have worse health and have higher need of medical care than elderly without need for long-term care. Yet, characteristics associated with long-term care need can impede health care access: Higher levels of long-term care need come with physical and cognitive decline such as frailty and memory loss. Yet, it has not been investigated whether level of long-term care need is related to medical care utilization. METHODS: We investigated the association between the level of long-term care and medical specialist utilization among nursing home residents and home care recipients. We applied zero-inflated Poisson regression with robust standard errors based on a sample of statutory health insurance members. The sample consisted of 100.000 elderly over age 60. We controlled for age, gender, morbidity and mortality, residential density, and general practitioner utilization. RESULTS: We found a strong gradient effect of the level of long-term care for 9 out of 12 medical specialties: A higher level of long-term care need was associated with a lower probability of having a medical specialist visit. Yet, we did not find clear effects of the level of long-term care need on the intensity of medical specialist care. These findings were similar for both the nursing home and home care setting. CONCLUSION: The findings indicate that inequalities in medical specialist utilization exist between elderly with differing levels of long-term care need because differences in morbidity were controlled for. Elderly with higher need of long-term care might face more access barriers to specialist medical care.

Needs-based provision of medical care to nursing home residents: protocol for a mixed-methods study.

INTRODUCTION: Nursing home residents typically have greater needs for medical care than community-dwelling elderly. However, restricted cognitive abilities and limited mobility may impede their access to general practitioners and medical specialists. The provision of medical care in nursing homes may therefore be inappropriate in some areas of medical care. The purpose of this mixed-methods study is to systematically assess, evaluate and explain met and unmet medical care needs in German nursing homes and to develop solutions where medical care is found to be inappropriate. METHODS AND ANALYSIS: First, statutory health insurance claims data are analysed to identify differences in the utilisation of medical care between nursing home residents and community-dwelling elderly with and without need for long-term care. Second, the health status and medical care of 500 nursing home residents are assessed and evaluated to quantify met and unmet medical care needs. Third, qualitative expert interviews and case conferences and, fourth, quantitative analyses of linked data are used to provide structural, case-specific and generalisable explanations of inappropriate medical care among nursing home residents. Fifth, a modified Delphi study is employed to develop pilot projects aiming to improve medical care in nursing homes. ETHICS AND DISSEMINATION: This study was approved by the Ethics Committee of the University of Bremen on 23 November 2017. Research findings are disseminated through presentations at national and international conferences and publications in peer-reviewed scientific journals. TRIAL REGISTRATION NUMBER: DRKS00012383.

Detecting and Visualizing Outliers in Provider Profiling Using Funnel Plots and Mixed Effects Models-An Example from Prescription Claims Data.

When prescribing a drug for a patient, a physician also has to consider economic aspects. We were interested in the feasibility and validity of profiling based on funnel plots and mixed effect models for the surveillance of German ambulatory care physicians' prescribing. We analyzed prescriptions issued to patients with a health insurance card attending neurologists' and psychiatrists' ambulatory practices in the German federal state of Saarland. The German National Association of Statutory Health Insurance Physicians developed a prescribing assessment scheme (PAS) which contains a systematic appraisal of the benefit of drugs for so far 12 different indications. The drugs have been classified on the basis of their clinical evidence as "standard", "reserve" or "third level" medication. We had 152.583 prescriptions in 56 practices available for analysis. A total of 38.796 patients received these prescriptions. The funnel plot approach with additive correction for overdispersion was almost equivalent to a mixed effects model which directly took the multilevel structure of the data into account. In the first case three practices were labeled as outliers, the mixed effects model resulted in two outliers. We suggest that both techniques should be routinely applied within a surveillance system of prescription claims data.

Is the built environment associated with morbidity and mortality? A systematic review of evidence from Germany.

The empirical evidence on this relationship mainly comes from Anglo-American countries whereas evidence from Germany is only emerging. Our objective is to provide a narrative overview and critical appraisal of the existing empirical evidence on the relationship between the built environment and morbidity/mortality in Germany. We conducted a systematic literature search where we included all empirical studies that linked the built environment aspects with morbidity or mortality outcomes. Findings were summarized and critically evaluated according to the Newcastle Ottawa Scale. Eighteen studies met the inclusion criteria and underwent in-depth analysis. Findings indicate that traffic exposure and green space tend to be associated with acute respiratory symptoms but not with chronic respiratory conditions. Evidence was inconsistent for the role of infrastructural aspects and urbanicity. Our review confirms the well-established association between traffic and respiratory health. Yet, the consistency between self-reported and objective measures of respiratory health should be investigated in more detail.
