Input: Two cluster-randomised control trials were included: one randomised at hospital level (23 hospitals in Australia) and one at ward level (16 wards in the UK). The primary outcome in the Australian trial (a composite score comprising incidence of unexpected cardiac arrests, unexpected deaths and unplanned ICU admissions) showed no statistical significant difference between control and medical emergency team (MET) hospitals (adjusted P value 0.640; adjusted odds ratio (OR) 0.98; 95% confidence interval (CI) 0.83 to 1.16). The UK-based trial found that outreach reduced in-hospital mortality (adjusted OR 0.52; 95% CI 0.32 to 0.85) compared with the control group. The evidence from this review highlights the diversity and poor methodological quality of most studies investigating outreach. The results of the two included studies showed either no evidence of the effectiveness of outreach or a reduction in overall mortality in patients receiving outreach. The lack of evidence on outreach requires further multi-site RCT's to determine potential effectiveness.
Output:

This summary of a Cochrane review presents what we know from research about the effect of outreach services for patients on general hospital wards. The review found two studies which were of good quality. One study compared 12 hospitals with outreach services to 11 that did not. Another study compared 16 wards with outreach to general wards without outreach. One of the studies showed that outreach reduced the number of hospital deaths, while the other study found no differences between hospitals with outreach and those with no outreach. It is not clear whether outreach reduces hospital deaths or ICU admissions. High quality research is needed to determine the effect of outreach services.
