Trial Outcomes & Findings for Impact of Heart Failure Center Program on Cardiac Outcomes in Patients With Heart Failure (NCT NCT01416285)

NCT ID: NCT01416285

Last Updated: 2024-03-08

Results Overview

Follow-up began after randomization. Follow-up data were prospectively obtained every month from hospital records, personal communication with patients' physicians, telephone interviews, and records of regular visits to staff physicians' outpatient clinics. 'Re-hospitalization'was defined as heart failure-related re-hospitalization.'All causes of death' was also considered to be an event. All-cause death was chosen as an endpoint because of the inter-relationship of heart failure with many other comorbidities in the patient cohort. A committee of three cardiologists adjudicated all hospitalizations without knowledge of the patients' clinical data to determine whether events were related to worsening heart failure. Based on these two different endpoints, time to the first event was analyzed.

Participant Flow

The study enrolled patients consecutively hospitalized for acute or decompensated chronic heart failure in the heart failure center of Chang Gung Memorial Hospital, Keelung, Taiwan from June 1, 2010 to May 30, 2012.

Of 470 enrolled participants, 121 were excluded (42 were excluded because of met exclusion criteria, 42 refused to participate, and 26 were excluded because of other reasons) , 349 met inclusion criteria and randomized to into the control and the case management groups.

PRIMARY outcome

Timeframe: 2 year

Population: Death, HF-related rehospitalization, and composite of death and HF-related rehospitalization

Follow-up data were prospectively obtained every month from hospital records, personal communication with patients' physicians, telephone interviews, and records of regular visits to staff physicians' outpatient clinics. 'Re-hospitalization'was defined as heart failure-related re-hospitalization.'All causes of death' was also considered to be an event.
