[Guideline compliance in the treatment of patients with chronic heart failure through family doctor-centred health care: results of an evaluation study].
OBJECTIVE
Family doctor centred health care (German abbreviation: HzV) agreements in Baden-Wuerttemberg provides that every year the strategies and results of at least two high-quality guidelines shall be discussed and worked on in quality circles. In this regard, the 'heart failure' guideline by the German Society of General Practice and Family Medicine (DEGAM) is especially important due to the high treatment costs and the continuously increasing prevalence of this medical condition. Another specified objective of the HzV agreements is to increase the DMP participation rate. The study addressed two questions: Is the medical care provided to patients with chronic heart failure who are being treated under HzV more compliant with guidelines than routine care? Does further improvement result from working on the guidelines in quality circles?


METHODS
Routine data were provided by the AOK Baden-Wuerttemberg statutory health insurance company. Patients with heart failure receiving treatment under an HzV agreement (HzV group) were compared with patients receiving routine care (control group) with regard to quality of care eight months before and eight months after working on the guideline on heart failure in quality circles. Primary endpoints were the prescription of ACE inhibitors, AT1 antagonists and beta blockers in accordance with guidelines. Adjustment for various covariates was done by means of multivariate multilevel regression.


RESULTS
Data were available for 3,667 practices [1,295 HzV practices; 2,158 non-HzV practices]. After applying validated diagnosis criteria, 16,584 patients were included in the intervention group and 28,992 in the control group. The HzV group received significantly better care in terms of the primary endpoint "prescription of ACE inhibitors or AT1 antagonists" (73.1 % vs. 69.3 % of the patients received ACE inhibitors or AT1 antagonists at T0 (OR 1.40; 95% CI [1,25; 1,57]; p < .001). 54.2 % vs. 52.3 % of the patients received beta blockers at T0 (not significant after adjustment, p = .260). No further improvement could be demonstrated to result from working on guidelines in quality circles.


CONCLUSIONS
The treatment of HzV patients with chronic heart failure is more compliant with guidelines than that of patients receiving routine care. Quality of care was already high at the beginning, and working on guidelines in quality circles had no noticeable effect. The increased DMP participation rate, which is one of the specified objectives of the HzV agreements, appears to have a mediation effect.
