Objectives: To implement multidisciplinary team care (MTC) and improve care quality for patients with heart failure (HF) through a task-oriented quality control story. Methods: We assembled a quality control circle (QCC) of various medical personnel to improve HF care quality. In-hospital patients with HF and reduced ejection fraction (HFrEF) were recruited for MTC. Quality indicators comprised length of hospitalization (LoH), 3-month rehospitalization rate, rate of consultation with a dietitian, rehabilitation engagement rate, and guideline-directed medication prescription rate. Results: The intervention involved 15 patients with HFrEF (age: 59.4 ± 14.9 years); the control group (before intervention) comprised 36 patients (age: 63.6 ± 14.4 years). After intervention, the LoH decreased from 10.6 to 7.2 days and 3-month rehospitalization rate decreased from 33.3% to 0% (p < 0.05). The rate of consultation with a dietitian increased from 3.9% to 100%, and the rehabilitation engagement rate increased from 47.2% to 100%. In the following year, the LoH and 3-month rehospitalization rate remained at 6.8 days and 8.7%, respectively. Conclusions: MTC is the gold-standard model for HF management, but diversities in specialist opinions may require improved communication. According to our experience, a QCC may provide straightforward integration of multidisciplinary resources, thus improving HF care quality.
