Objective: For most patients with depression, GPs are the first and long-term medical providers. GP-centered health care (GPc-HC) programs target patients with chronic diseases. What are the effects of GPc-HC on primary care depression management?
Method: An observational retrospective case-control study was conducted using health insurance claims data of patients with depressive disorder from July 2011 to December 2012.
Results: From 40,298 patients insured with the largest health plan in Central Germany participating in the GPc-HC program (intervention group, IG), we observed 4645 patients with depression over 18months: 72.2% women; 66.6years (mean); multiple conditions (morbidity-weight 2.50 (mean), 86%>1.0). We compared them with 4013 patients who did not participate (control group). In participants we found lower number of incomplete/non-specified depression diagnoses (4.46vs.4.82;MD-0.36; p<0.01); lower rate of patients consulting more than one GP-practice (49.1%vs.58.0%;PP-8.9;p<0.01); more GP-contacts (18.19vs.15.59;MD+2.60;p<0.01); more GP-initiated referrals to specialists (82.9%vs.79.3%;PP+3.6;p<0.05), more antidepressant pharmacotherapy prescribed by a GP (37.9%vs.35.4%;PP+2.5;p<0.05), more frequent guideline-concordant therapy duration (19.2%vs.13.1%;PP+6.1;p<0.01) and more patients receiving "GP-psychosomatic basic care" (38.2%vs.30.2%;PP+8.0;p<0.01).
Conclusion: Depressive patients participating in a GPc-HC program may be more often diagnosed by a GP, receive symptom-monitoring and appropriate depression treatment.
