IntroductionIncreases in emergency department (ED) demand may compromise patient outcomes, leading not only to overcrowding in the ED, increased ED waiting times and increased ED length of stay, but also compromising patient safety; the risk of adverse events is known to rise in the presence of overcrowding. Hospital in the home (HiTH) services may offer one means of reducing ED demand.AimThis integrative review sought to assess the efficacy of admission-avoidance HiTH services that admit patients directly from the ED.MethodsPapers published between 1995 and 2013 were identified through searches of Medline, CINAHL and Google. English-language studies that assessed the efficacy of a HiTH service and that recruited at least one-third of the participants directly from the ED were included in the review. A HiTH service was considered one that provided health professional support to patients at home for a time-limited period, thus avoiding the need for hospitalization.ResultsTwenty-two articles met the inclusion criteria for this review. The interventions were diverse in terms of the clinical interventions delivered, the range and intensity of health professional input and the conditions treated. The studies included in the review found no effect on clinical outcomes, rates of adverse events or complications, although patient satisfaction and costs were consistently and favourably affected by HiTH treatment.ConclusionGiven evidence suggesting that HiTH services which recruit patients directly from the ED contribute to cost-savings, greater patient satisfaction and safety and efficacy outcomes that are at least equivalent to those associated with hospital-based care, the expansion of such programmes might therefore be considered a priority for policy makers.
