Development of an interprofessional person-centred care concept for persons with care needs living in their own homes (interprof HOME): study protocol for a mixed-methods study.

INTRODUCTION: People receiving home care usually have complex healthcare needs requiring the involvement of informal caregivers and various health professionals. In this context, successful collaboration is an important element of person-centred care, which is often insufficiently implemented. Consequences might be found in avoidable hospitalisations. The aim of the study is to develop a care concept to improve person-centred interprofessional collaboration for people receiving home care considering the perspectives of all person groups involved. METHODS AND ANALYSIS: This study uses a mixed-methods design consisting of a literature review, several qualitative inquiries, a cross-sectional quantitative study and a final structured workshop. After a literature review (work package (WP) 1), we will explore the perspectives of people receiving home care (n=20), their relatives (n=20) and representatives of statutory health insurances (n=5) in semistructured interviews (WP2). Moreover, 100 individuals of each group (people receiving home care, relatives, registered nurses, general practitioners and therapists) involved in home care will answer a survey on collaboration that will be analysed descriptively (WP3). Additionally, monoprofessional focus groups (n=9) of registered nurses, general practitioners and therapists, respectively, will discuss current practices. Data will be analysed by qualitative content analysis. Best practice cases (n=8) will be analysed by a case-based qualitative content analysis based on data of observations of home visits and interviews (WP4). The findings of WP2 will be discussed in mixed focus groups (n=4) with 10 participants each (WP5). Considering the results of joint displays of WP3, WP4 and WP5, the interprofessional care concept and its implementation will be elaborated in an expert workshop (WP6). ETHICS AND DISSEMINATION: Ethical approval was obtained from all ethics committees of the project partners. Study results will be disseminated through publications, conference presentations, student education and advanced training of health professionals. TRIAL REGISTRATION NUMBER: NCT05149937.

Cost-Effectiveness of Inter-Professional Collaboration to Reduce Hospitalisations in Nursing Home Residents: Results from the German Interprof ACT Trial.

Background: The German multi-centre cluster-randomised controlled trial interprof ACT investigated interventions to increase inter-professional collaboration between nursing home (NH) staff and local general practitioners to reduce hospitalisations and improve nursing homes residents' (NHRs) quality of life. The trial was funded by the German Health Care Innovation Fund. Methods: Cost-effectiveness of interprof ACT interventions was evaluated and compared to current standard of care (SOC) over 12 months, including 622 NHRs in 34 NHs in Germany. Multiplying resource use of healthcare services with German-specific unit costs generated costs. Health outcome was measured in quality-adjusted life-years QALYs), utility by multiplying EQ-5D-5L values with German-specific utility weights. Incremental cost-effectiveness analysis used an intention-to-treat approach and scenario analyses (SAs). Net-benefit-regression and cost-effectiveness acceptability curves addressed uncertainty. A German healthcare insurance perspective was assumed. Results: Base case results showed non-significant cost savings of 851.88€ and non-significant QALY loss of -0,056. Discussion: Dependency levels at baseline were non-significantly higher in IG compared to control group (CG). Lack of baseline costing data eliminated possibility to evaluate changes in costs due to the interprof ACT measures for both groups. Conclusion: Interprof ACT interventions are not cost-effective compared to current SOC.

Cluster randomised trial of a complex interprofessional intervention (interprof ACT) to reduce hospital admission of nursing home residents.

BACKGROUND: Some hospital admissions of nursing home residents (NHRs) might be attributed to inadequate interprofessional collaboration. To improve general practitioner-nurse collaboration in nursing homes (NHs), we developed an intervention package (interprof ACT) in a previous study. OBJECTIVE: To assess the impact of interprof ACT on the proportion of hospitalisation and other clinical parameters within 12 months from randomisation among NHRs. METHODS: Multicentre, cluster randomised controlled trial in 34 German NHs. NHRs of the control group received usual care, whereas NHRs in the intervention group received interprof ACT. Eligible NHs had at least 40 long-term care residents. NHs were randomised 1:1 pairwise. Blinded assessors collected primary outcome data. RESULTS: Seventeen NHs (320 NHRs) were assigned to interprof ACT and 17 NHs (323 NHRs) to usual care. In the intervention group, 136 (42.5%) NHRs were hospitalised at least once within 12 months from randomisation and 151 (46.7%) in the control group (odds ratio (OR): 0.82, 95% confidence interval (CI): [0.55; 1.22], P = 0.33). No differences were found for the average number of hospitalisations: 0.8 hospitalisations per NHR (rate ratio (RR) 0.90, 95% CI: [0.66, 1.25], P = 0.54). Average length of stay was 5.7 days for NHRs in the intervention group and 6.5 days in the control group (RR: 0.70, 95% CI: [0.45, 1.11], P = 0.13). Falls were the most common adverse event, but none was related to the study intervention. CONCLUSIONS: The implementation of interprof ACT did not show a statistically significant and clinically relevant effect on hospital admission of NHRs.

Implementation, mechanisms of change and contextual factors of a complex intervention to improve interprofessional collaboration and the quality of medical care for nursing home residents: study protocol of the process evaluation of the interprof ACT intervention package.

BACKGROUND: To improve interprofessional collaboration between registered nurses (RNs) and general practitioners (GPs) for nursing home residents (NHRs), the interprof ACT intervention package was developed. This complex intervention includes six components (e.g., shared goal setting, standardized procedures for GPs' nursing home visits) that can be locally adapted. The cluster-randomized interprof ACT trial evaluates the effects of this intervention on the cumulative incidence of hospital admissions (primary outcome) and secondary outcomes (e.g., length of hospital stays, utilization of emergency care services, and quality of life) within 12 months. It also includes a process evaluation which is subject of this protocol. The objectives of this evaluation are to assess the implementation of the interprof ACT intervention package and downstream effects on nurse-physician collaboration as well as preconditions and prospects for successive implementation into routine care. METHODS: This study uses a mixed methods triangulation design involving all 34 participating nursing homes (clusters). The quantitative part comprises paper-based surveys among RNs, GPs, NHRs, and nursing home directors at baseline and 12 months. In the intervention group (17 clusters), data on the implementation of preplanned implementation strategies (training and supervision of nominated IPAVs, interprofessional kick-off meetings) and local implementation activities will be recorded. Major outcome domains are the dose, reach and fidelity of the implementation of the intervention package, changes in interprofessional collaboration, and contextual factors. The qualitative part will be conducted in a subsample of 8 nursing homes (4 per study group) and includes repeated non-participating observations and semistructured interviews on the interaction between involved health professionals and their work processes. Quantitative and qualitative data will be descriptively analyzed and then triangulated by means of joint displays and mixed methods informed regression models. DISCUSSION: By integrating a variety of qualitative and quantitative data sources, this process evaluation will allow comprehensive assessment of the implementation of the interprof ACT intervention package, the changes induced in interprofessional collaboration, and the influence of contextual factors. These data will reveal expected and unexpected changes in the procedures of interprofessional care delivery and thus facilitate accurate conclusions for the further design of routine care services for NHRs.
