Importance: Hospital-at-home (HaH) care provides acute hospital-level care in a patient's home as a substitute for traditional inpatient care. In September 2017, the Physician-Focused Payment Model Technical Advisory Committee recommended implementation of an alternative payment model for a new model of HaH that bundles the acute episode with 30 days of postacute transitional care.
Objective: To report outcomes of this new payment model for HaH care.
Design, setting, and participants: Case-control study of HaH care patients with a concurrent control group of hospital inpatients recruited from emergency departments (EDs) and residences in New York City from November 18, 2014, to August 31, 2017. HaH patients were 18 years or older with fee-for-service Medicare and acute medical illness requiring inpatient-level care. Control patients met HaH eligibility but refused participation or were seen in the ED when a HaH admission could not be initiated.
Exposures: HaH care or inpatient care.
Main outcomes and measures: Primary outcomes were acute period length of stay (LOS), all-cause 30-day hospital readmissions and ED visits, admissions to skilled nursing facilities (SNFs), referral to a certified home health care agency, and patient experiences with care. Analyses accounted for nonrandom selection using inverse probability weighting.
Results: Among the 507 patients enrolled (mean [SD] age, 74.6 [15.7] years; 68.6% women), data were available on all patients 30 days postdischarge. HaH patients (n = 295) were older than controls (n = 212) and more likely to have a preacute functional impairment. HaH patients had shorter LOS (3.2 days vs 5.5 days; difference, -2.3 days; 95% CI, -1.8 to -2.7 days; weighted P < .001); lower rates of readmissions (8.6% [25] vs 15.6% [32]; difference, -7.0%; 95% CI, -12.9% to -1.1%; weighted P < .001), ED revisits (5.8% [17] vs 11.7% [24]; difference, -5.9%; 95% CI, -11.0% to -0.7%; weighted P < .001), and SNF admissions (1.7% [5] vs 10.4% [22]; difference, -8.7%; 95% CI, -13.0% to -4.3%; weighted P < .001); and were also more likely to rate their hospital care highly (68.8% [119] vs 45.3% [67]; difference, 23.5%; 95% CI, 12.9% to 34.1%; weighted P < .001). There were no differences in referrals to certified home health agencies.
Conclusions and relevance: HaH care bundled with a 30-day postacute transitional care episode was associated with better patient outcomes and ratings of care compared with inpatient hospitalization. This model warrants consideration for addition to Medicare's current portfolio of shared savings programs.
