Abstract   Aims  This study sought to compare healthcare quality and 30 day, 90 day, and 1 year mortality rates among patients admitted to secondary and tertiary hospitals for heart failure (HF) in Beijing.    Methods and results  This study retrospectively enrolled patients hospitalized with a primary discharge diagnosis of HF during January 2014 to December 2015, from five tertiary and four secondary hospitals, in Beijing, China. Mortality data were extracted from Beijing Death Surveillance Database. HF healthcare quality indices were used to evaluate in‐hospital care. Associations between hospital level and mortality rates were assessed using generalized linear mixed models, adjusting for patients' baseline characteristics and intra‐hospital correlation. Data from 1413 patients (median [interquartile range] age = 74 [65–80] years, 52.7% female) from secondary hospitals and 1250 patients (median [interquartile range] age = 72 [61–79] years, 43.3% female) from tertiary hospitals were collected. Rates of left ventricular ejection fraction assessment (73.2% vs. 90.1%) and combined use of β‐blockers and angiotensin‐converting enzyme inhibitors/angiotensin II receptor blockers (30.1% vs. 49.3%) were lower in secondary hospitals than those in tertiary hospitals, respectively. Patients admitted to secondary hospitals had a higher 90 day mortality [10.8% vs. 5.0%; adjusted odds ratio (OR): 2.06; 95% confidence interval (CI): 1.10–3.84,  P  = 0.024 and a higher 1 year mortality rate [21.0% vs. 12.1%; adjusted OR: 1.64; 95% CI: 1.02–2.62,  P  = 0.039], but 30 day mortality rates were not significantly different (5.5% vs. 3.0%; adjusted OR: 1.49; 95% CI: 0.63–3.52,  P  = 0.368).    Conclusions  Worse quality of care for patients with HF in secondary hospitals was associated with higher 90 day and 1 year mortality rates. Improving care quality in secondary hospitals is crucial to improve prognosis of patients they served.
