BackgroundHospital at home is defined as a service that provides active treatment by health care professionals, in the patient's home, of a condition that otherwise would require acute hospital in-patient care, always for a limited period.ObjectivesTo assess the effects of hospital at home compared with in-patient hospital care.Search StrategyWe searched the Cochrane Effective Practice and Organisation of Care Group (EPOC) specialised register (November 2004), MEDLINE (1966 to 1996), EMBASE (1980 to 1995), Social Science Citation Index (1992 to 1995), Cinahl (1982 to 1996), EconLit (1969 to 1996), PsycLit (1987 to 1996), Sigle (1980 to 1995) and the Medical Care supplement on economic literature (1970 to 1990).Selection CriteriaRandomised trials of hospital at home care compared with acute hospital in-patient care. The participants were patients aged 18 years and over.Data Collection And AnalysisTwo reviewers independently extracted data and assessed study quality.Main ResultsTwenty two trials are included in this update of the review. Among trials evaluating early discharge hospital at home schemes we found an odds ratio (OR) for mortality of 1.79 95% CI 0.85 to 3.76 for elderly medical patients (age 65 years and over) (n = 3 trials); OR 0.58; 95% CI 0.29 to 1.17 for patients with chronic obstructive pulmonary disease (COPD) (n = 5 trials); and OR 0.78; 95%CI 0.52 to 1.19 for patients recovering from a stroke (n = 4 trials). Two trials evaluating the early discharge of patients recovering from surgery reported an OR 0.43 (95% CI 0.02 to 10.89) for patients recovering from a hip replacement and an OR 1.01 (95% CI 0.37 to 2.81) for patients with a mix of conditions at three months follow-up. For readmission to hospital we found an OR 1.76; 95% CI 0.78 to 3.99 at 3 months follow-up for elderly medical patients (n = 2 trials); OR 0.81; 95% CI 0.55 to 1.19 for patients with COPD (n = 5 trials); and OR 0.96; 95% CI 0.63 to 1.45 for patients recovering from a stroke (n = 3 trials). No significant heterogeneity was observed. One trial recruiting patients following surgery for hernia or varicose veins reported 0/117 versus 2/121 patients were re admitted (Ruckley 1978); another that 2/37 (5%) versus 1/49 (2%) (difference 3%, 95% CI -5% to 12%) of patients recovering from a hip replacement, 4/47 (9%) versus 1/39 (3%) (difference 6%, 95% CI -3% to 15%) of patients recovering from a knee replacement, and 7/114 (6%) versus 13/124 (10%) (difference -4% 95% CI -11% to 3%) of patients recovering from a hysterectomy were readmitted. A third trial analysing surgical and medical patients together reported that 42/159 versus 17/81 patients were readmitted at 3 months (OR 1.34 95% CI 0.66 to 2.20). Allocation to hospital at home resulted in a small reduction in hospital length of stay, but hospital at home increased overall length of care. Patients allocated to hospital at home expressed greater satisfaction with care than those in hospital, while the view of carers was mixed.Authors' ConclusionsDespite increasing interest in the potential of hospital at home services as a cheaper alternative to in-patient care, this review provides insufficient objective evidence of economic benefit. Early discharge schemes for patients recovering from elective surgery and elderly patients with a medical condition may have a place in reducing the pressure on acute hospital beds, providing the views of the carers are taken into account. For these clinical groups hospital length of stay is reduced, although this is offset by the provision of hospital at home. Future primary research should focus on rigorous evaluations of admission avoidance schemes and standards for original research should aim at assisting future meta-analyses of individual patient data from these and future trials.
