Approximately 50\% of hospitalised patients have a low mortality risk by DECAF, thus are potentially suitable.Methods In a non-inferiority randomised controlled trial, 118 patients admitted with a low-risk ECOPD (DECAF 0 or 1) were recruited to HAH or usual care (UC). The primary outcome was health and social costs at 90 days.Results Mean 90-day costs were {\textsterling}1016 lower in HAH, but the one-sided 95\% CI crossed the non-inferiority limit of {\textsterling}150 (CI -2343 to 312). Savings were primarily due to reduced hospital bed days: HAH=1 (IQR 1{\textendash}7), UC=5 (IQR 2{\textendash}12) (P=0.001). Length of stay during the index admission in UC was only 3 days, which was 2 days shorter than expected. Based on quality-adjusted life years, the probability of HAH being cost-effective was 90\%. There was one death within 90 days in each arm, readmission rates were similar and 90\% of patients preferred HAH for subsequent ECOPD.Conclusion HAH selected by low-risk DECAF score was safe, clinically effective, cost-effective, and preferred by most patients. Compared with earlier models, selection is simpler and approximately twice as many patients are eligible. The introduction of DECAF was associated with a fall in UC length of stay without adverse outcome, supporting use of DECAF to direct early discharge.Trial registration number Registered prospectively ISRCTN 29082260.}, issn = {0040-6376}, URL = {https://thorax.bmj.com/content/early/2018/04/21/thoraxjnl-2017-211197}, eprint = {https://thorax.bmj.com/content/early/2018/04/21/thoraxjnl-2017-211197.full.pdf}, journal = {Thorax} }
