A DNP student has finished collecting the data for his/her DNP quality improvement project. The DNP student recruited 30 adults admitted to Johns Hopkins Hospital (JHH) and Johns Hopkins Bayview Medical Center (JHBMC) for heart failure. 15 participants were assigned to both the intervention and control group. The intervention group received education on salt intake, fluid restriction, weight management, and medications, as well as a follow-up telephone call at 2 weeks post-discharge. Participants in the control group received usual care and education for the hospital to which they were admitted. The primary aim of this DNP project is to test the effect of the intervention on reducing unplanned all-cause 30-day readmission rates. Secondary aims of the DNP project include (1) assessing the difference in heart failure knowledge scores between treatment groups and (2) assessing the relationship between heart failure class, attending provider, and length of hospital stay with unplanned all-cause 30-day readmission rates. The student collected his/her data from EPIC, surveys conducted via Qualtrics, as well as the JHH/JHBMC claims/readmission database. In order to merge data collected from EPIC and the JHH/JHBMC claims/readmission database the student collected medical record numbers for each participant.
