Methods: This study was a prospective cohort design with a historical comparison group. It was conducted to assess the difference in 30-day readmissions and mortality and to assess compliance rate with HF guideline between the historical pre-intervention audit 1 cohort and prospective post-intervention audit 2 cohorts. Audit 1 cohort were recruited from January to February 2019, whereas, audit 2 cohort which received the bundled intervention program were recruited from July to December 2019. Clinical outcomes were compared between cohorts using 30-day readmissions and mortality.

Results: A total of 50 and 164 patients were included in audit 1 and audit 2 cohort, respectively. Patients in the audit 2 cohort were younger [63.0 ± 14.5 in audit 1 vs 56.5 ± 12.7 in audit 2, p = 0.003] and majority were male [50.0% in audit 1 vs 72.0% in audit2, p = 0.004]. Thirty-day readmissions were significantly different [36.0% audit 1 vs. 22.0% audit 2, p = 0.045], but the mortality rates were similar [4.0%% audit 1 vs. 5.5% audit 2, p = 0.677] between two cohorts.
