Association between Periodontal Treatment and Healthcare Costs in Patients with Coronary Heart Disease: A Cohort Study Based on German Claims Data.

There is empirical evidence of an association between periodontitis and coronary heart disease (CHD). However, it is uncertain whether periodontal treatment in CHD patients might lead to reduced healthcare costs. This study aims to assess the association between periodontal treatment and healthcare costs in newly diagnosed CHD patients. Data from 21,263 adults who were continuously insured between 2011 and 2016 and who were newly diagnosed with CHD in 2013 were selected from a German claims database. The study population was differentiated by the utilization of periodontal treatment. The average treatment effect (ATE) of periodontal treatment on healthcare costs (total, inpatient, outpatient, drugs) was investigated using weighted Poisson regression models conditional on covariates and is shown as a ratio (of geometric means). Periodontal treatment was documented for 4.7% of the persons in the study population. Newly diagnosed CHD patients showed an ATE of 0.98 for total healthcare cost (95% CI 0.90-1.06), 0.79 for inpatient costs (95% CI 0.61-1.04), and 0.95 for drug costs (95% CI 0.87-1.04). A statistically significant 7% increase in outpatient costs was shown (95% CI 1.01-1.13). Despite a lack of statistical significance in most cases, the study provides evidence of a meaningful decrease in inpatient costs after periodontal treatment. Further studies are needed.

A Cross-Provider Healthcare Management Program for Musculoskeletal Disorders: Results of a Randomized Controlled Trial in 22 German Companies.

Musculoskeletal disorders (MSDs) are among the most common cause for reduced work capacity and sick leave. Workplace health promotion programs are often neither tailored to the workplace nor the individual needs of the employees. To counteract lacking intersectional care, this four-year randomized controlled trial (RCT) aimed to investigate the effects of modular coordinating case management (treatment group) compared to supported self-management (control group) on MSD specific sick leave days (routine data), workability (WAI), self-efficacy (self-efficacy scale), and pain (German pain questionnaire, GPQ). The study network comprised 22 companies, 15 company health insurance funds, and 12 pension funds in Germany. Overall, 852 participants (Module A/early intervention: n = 651, Module B/rehabilitation: n = 190, Module C/reintegration: n = 10) participated. Both groups achieved fewer sick leave days, higher workability, and less pain (p < 0.0001) at follow-up compared to baseline. At follow-up, the coordinating case management group showed fewer disability days (GPQ), lower disability scores (GPQ), and lower pain intensities (GPQ) than the supported self-management group (p < 0.05), but no superiority regarding MSD specific sick leave days, workability, nor self-efficacy. Module A showed more comprehensive differences. The accompanying process evaluation shows barriers and facilitators for the implementation of the program, especially in a RCT setting.

The impact of periodontal treatment on healthcare costs in newly diagnosed diabetes patients: Evidence from a German claims database.

AIMS: There is sufficient scientific evidence for the bidirectional association between periodontal diseases and diabetes. In this context, we hypothesized that periodontal treatment leads to lower healthcare costs in newly diagnosed diabetes patients by promoting a milder disease course. METHODS: A total of 23,771 persons were investigated who were continuously insured by German health insurances between 2011 and 2016, 18 years or older, and newly diagnosed with diabetes in 2013. The study population was divided into a periodontal treatment and control group (no periodontal treatment). The average treatment effect of a periodontal treatment on various types of healthcare costs (inpatient, outpatient, drug costs) was analyzed by a doubly robust method. RESULTS: Finally, 5.3% of the study population could be assigned to the treatment group. In newly diagnosed diabetes patients with periodontal treatment, a reduction in total healthcare costs (0.96, 95%CI 0.89; 1.04), inpatient costs (0.87, 95%CI 0.69; 1.08), diabetes-related drug costs (0.93, 95%CI 0.84; 1.03) and other drug costs (0.97, 95%CI 0.89; 1.05) could be shown compared to the control group. CONCLUSIONS: This study provides evidence that periodontal treatment for diabetes patients reduces healthcare costs. Fewer diabetes-specific complications and hospitalizations are expected.

Evaluation of a complex integrated, cross-sectoral psycho-oncological care program (isPO): a mixed-methods study protocol.

INTRODUCTION: International standards of care require the complete integration of psycho-oncological care into biomedical cancer treatment. The structured integrated, cross-sectoral psycho-oncological programme 'isPO' is aiming to ensure a provision of care in inpatient and outpatient settings according to a stepped-care approach. Up to now, psycho-oncological care is missing regulated and standardised processes to demonstrate the effectiveness. This study protocol describes the process and outcome evaluation that is conducted, along with the isPO study. The programme evaluation is aiming to proof effectiveness, explain potential discrepancies between expected and observed outcomes. Additionally, provide insight into the implementation process, as well as contextual factors that might promote or inhibit the dissemination and implementation of the stepped care programme will be gained. In addition to these measures, a cost-consequence analysis will provide further evidence aimed at integrating psycho-oncological care into primary healthcare. METHODS AND ANALYSIS: The evaluation concept is based on a tripartite strategy consisting of a prospective, formative and summative evaluation. To capture all determinants, a concurrent mixed-method design is applied comprising qualitative (interviews and focus groups) and quantitative (standardised questionnaires) surveys of patients and healthcare providers. In addition, analysis of the psycho-oncological care data (isPO care data) and statutory health insurance claims data will be conducted. Primary and secondary data will complement one another (data linkage) to obtain a more comprehensive picture of the effectiveness and implementation of the complex intervention within the isPO study. ETHICS AND DISSEMINATION: The study has been approved by the ethics committee of the Medical Faculty of the University of Cologne. For all collected data, the relevant national and European data protection regulations will be considered. All personal identifiers (eg, name, date of birth) will be pseudonymised. Dissemination strategies include annual reports as well as quality workshops for the organisations, the presentation of results in publications and on conferences, and public relations.

Multidimensional analysis of factors responsible for the low prevalence of ambulatory peritoneal dialysis in Germany (MAU-PD): a cross-sectional Mixed-Methods Study Protocol.

INTRODUCTION: Patients with end-stage kidney failure can be treated either by transplant or by dialysis, which can be administered as haemodialysis (HD) or peritoneal dialysis (PD). Although they are equivalent therapeutic options in terms of mortality, the percentage of patients in Germany treated with PD is currently very low (∼6%) compared with other countries. The aim of our study is to analyse the factors behind this percentage and their relevance to the choice of dialysis treatment in Germany. This includes analyses of regional disparities in the provision of care for dialysis patients as well as the evaluations of costs and the influence of reimbursement structures. This approach should provide further insights to explain the variation in the usage of PD and HD and will help to define starting points for future interventions. METHODS AND ANALYSIS: A mixed-methods approach will be applied to several data sources, including administrative data (ambulatory physicians' claim data, statutory health insurance claim data), quality assurance data from one of the largest German dialysis providers Kuratorium für Dialyse (KfH) and qualitative and quantitative survey data (patients, nephrologists and dialysis nurses). Qualitative data will be analysed content-analytically. Based on the quantitative data, multivariable analyses will be performed and, where possible, hierarchical models will be tested. This multidimensional approach will enable us to account for the different factors influencing the penetration of PD in Germany. ETHICS AND DISSEMINATION: Ethics approval (17-299) has been obtained from the Ethics Committee of the Medical Faculty of the University of Cologne on 25 April 2018. National and international dissemination will be accomplished by informing healthcare practitioners, patients and professional organisations and other stakeholders via conferences, scientific and non-scientific publications and seminars.

Identifying cut-off scores for job demands and job control in nursing professionals: a cross-sectional survey in Germany.

OBJECTIVES: Nurses are generally found to be vulnerable to burnout, but nurses working in cancer care are even more so, since this profession is characterised by continuous confrontation with suffering and death. This study was designed to identify cut-off scores for job strain, that is, low job control and high job demands, for a sample of nurses working in breast cancer care. The main goal was to find cut-off scores, which predict the risk of nurses of developing a mental disorder from high job strain. DESIGN: The design was a cross-sectional survey study. SETTING: The study is based on an employee survey in breast cancer centres in Germany. PARTICIPANTS: 688 nurses received a questionnaire; 329 nurses from 33 hospitals participated in the survey (return rate: 50.2%). PRIMARY AND SECONDARY OUTCOME MEASURES: Dependent variable: psychological well-being, measured by the WHO-5 Well-being Index; independent variables: job control and job demands, measured by the Job Content Questionnaire (JCQ). RESULTS: Multivariable analysis indicates that low job control and high job demands are prognostic factors for low well-being. In a receiver operating curve (ROC) analysis, the cut-off scores, which demonstrated a maximum Youden index, were 34.5 for job control and 31.4 for job demands. The combination of both scales from a logistic regression analysis resulted in an area under the curve of 0.778. Sensitivity and specificity are 70.3% and 74.2%, respectively. The total of correct classification was 63.3%. CONCLUSION: The determined cut-off scores indicate that there is a risk of becoming psychologically ill from a high workload when an individual reaches a score of ≤34.5 for job control and ≥31.4 for job demands. The described method of establishing risk-based cut-off scores is promising for nursing practice and for the field of occupational health. Transferability and generalisability of the cut-off scores should be further analysed.
