Home ward bound: features of hospital in the home use by major Australian hospitals, 2011–2017

OBJECTIVE To describe uptake of hospital in the home (HIH) by major Australian hospitals and the characteristics of patients and their HIH admissions; to assess change in HIH admission numbers relative to total hospital activity. DESIGN Descriptive, retrospective study of HIH activity, analysing previously collected census data for all multi-day hospital inpatient admissions to included hospitals during the period 1 January 2011 - 31 December 2017. SETTING, PARTICIPANTS Nineteen principal referrer hospital members of the Health Roundtable in Australia. MAIN OUTCOME MEASURES HIH admissions by diagnosis-related group (DRG); patient and admission characteristics. RESULTS 80 167 of 2 185 421 admissions to the 19 hospitals included HIH care, or 3.7% (95% CI, 3.6-3.7%) of all admissions. Median length of stay for admissions including HIH (7.3 days; IQR, 3.1-14 days) was longer than that for those that did not (2.7 days; IQR, 1.6-5.1 days). For HIH admissions, the proportion of men was higher (54.4% v 45.9%), the proportion of patients who died in hospital was lower (0.3% v 1.4%), and re-admission within 28 days was less frequent (2.3% v 3.6%). The 50 DRGs with greatest HIH activity encompassed 65 811 HIH admissions (82.1%), or 8.4% (95% CI, 8.4-8.5%) of all admissions in these DRGs. HIH admission numbers grew more rapidly than non-HIH admissions, but the difference was not statistically significant. CONCLUSIONS HIH care is most frequently provided to patients requiring hospital treatment related to infections, venous thromboembolism, or post-surgical care. Its use could be expanded in clinical areas where it is currently used, and extended to others where it is not. HIH activity is growing. It should be systematically monitored and reported to allow better overview of its use and outcomes.
