Overview article: Impact of primary and secondary care collaboration on hospitalization for chronic heart failure: Two comparative studies.

INTRODUCTION: In the past decade, a legal framework was created in Germany that promotes intense collaboration at the interface between primary and secondary care. This overview article distinguishes between the effects of two complementary programs aimed at improving ambulatory care in Baden-Wuerttemberg: (1) general practitioner-centered care (GPCC), which strengthens the role of general practitioners, and (2) collaborative cardiology care (CCC), which coordinates primary and cardiology care. METHODS: The overview article presents two already published studies that assess the impact of the programs on hospitalizations in patients with chronic heart failure (CHF) based on claims data from 2016. The hospitalization rate of patients enrolled in GPCC (N=75,096) and CCC (N=13,404) were compared with corresponding control groups (N=65,618 and N=8,776 respectively). RESULTS: The hospitalization rate in GPCC was lower than in the control group (risk ratio 0.97; 95% CI: 0.95-0.99, P=0.0024). GPCC patients with CHF that received specialist cardiology care as part of CCC had significantly lower hospitalization rates than those receiving standard cardiology care (risk ratio 0.92; 0.88-0.97, P=0.0014). DISCUSSION: This overwiew study shows that reforming medical care and compensation at the interface between general practice and specialist care can lead to fewer hospital admissions in patients with CHF. CONCLUSION: Overall, this article underlines the importance of collaboration between primary care physicians and specialists for patients with CHF that are receiving ambulatory care.

Evaluation of a collaborative ambulatory orthopedic care program for patients with hip and knee osteoarthritis: a comparative observational cohort study.

BACKGROUND: In 2014, the novel orthopedic care program was established by the AOK health insurance fund in southern Germany to improve ambulatory care for patients with musculoskeletal disorders. The program offers extended consultation times, structured collaboration between general practitioners and specialists, as well as a renewed focus on guideline-recommended therapies and patient empowerment. The aim of this study was to assess the impact of the program on health service utilization in patients with hip and knee osteoarthritis (OA). METHODS: This retrospective cohort study, which is based on claims data, evaluated health service utilization in patients with hip and knee OA from 2014 to 2017. The intervention group comprised OA patients enrolled in collaborative ambulatory orthopedic care, and the control group received usual care. The outcomes were participation in exercise interventions, prescription of physical therapy, OA-related hospitalization, and endoprosthetic surgery rates. Generalized linear regression models were used to analyze the effect of the intervention. RESULTS: Claims data for 24,170 patients were analyzed. Data for the 23,042 patients in the intervention group were compared with data for the 1,128 patients in the control group. Participation in exercise interventions (Odds Ratio (OR): 1.781; 95% Confidence Interval (CI): 1.230-2.577; p = 0.0022), and overall prescriptions of physical therapy (Rate Ratio (RR): 1.126; 95% CI: 1.025-1.236; p = 0.0128) were significantly higher in the intervention group. The intervention group had a significantly lower risk of OA -related hospitalization (OR: 0.375; 95% CI: 0.290-0.485; p < 0.0001). Endoprosthetic surgery of the knee was performed in 53.8% of hospitalized patients in the intervention group vs. 57.5% in the control group; 27.7% of hospitalized patients underwent endoprosthetic surgery of the hip in the intervention group versus 37.0% in the control group. CONCLUSIONS: In patients with hip and knee OA, collaborative ambulatory orthopedic care is associated with a lower risk of OA-related hospitalization, higher participation in exercise interventions, and more frequently prescribed physical therapy.
