Abstract 357: Effect of an Early Nurse Practitioner Based Transitional Care Program on Atrial Fibrillation Readmissions
Background: BRIDGE is a nurse practitioner (NP) based transitional care program for cardiac patients(pts) discharged from a large tertiary care health system. Attendance at the BRIDGE clinic has been shown to reduce early readmission and ED visits for acute coronary syndrome (ACS) pts. Little is known about causes of readmission for atrial fibrillation (AF) pts and whether an NP based program affects overall readmissions. Methods: Retrospective data on 1188 pts was abstracted from 2008 to 2010 for pts referred to BRIDGE. Early (30 day) readmission of pts with discharge diagnosis of AF underwent qualitative chart audit by a trained MD abstractor. When examining if BRIDGE affected readmissions, we excluded pts with ED visits/readmits prior to BRIDGE. Results: Median time to BRIDGE was 16 days. Of 1010 with complete data, 148 (15%) had a discharge diagnosis of AF; 110/148 (74%) AF pts attended BRIDGE. Thirty day readmission (30DR) for AF was 23% (34/148); 17/34 (57%) were sent to the ED by a MD or nurse. Attending BRIDGE had no effect on outcomes at all time points (table 1); 17 patients were readmitted before BRIDGE. Readmission at 6 months for AF was 41% for those who attended BRIDGE, 29% for those who did not (p=0.190). Table 2 details reasons for all 30DR in AF pts. Chart review demonstrated that all 30DR were appropriate, 83% (25/30) of non-elective readmissions were unavoidable, and of 5 potentially avoidable readmissions, 2 were due to patient non-compliance. Conclusions: 30-day readmission rates are high for pts recently discharged with a diagnosis of AF and most are unavoidable. A NP based transitional care clinic successful in reducing 30 day readmissions for ACS pts did not prevent either early or late readmissions in AF pts.
