title: Safety of patients under the care of crisis resolution home treatment services in England: a retrospective analysis of suicide trends from 2003 to 2011.
abstract: BACKGROUND
  Community care provided by crisis resolution home treatment teams is used increasingly as an alternative to admission to psychiatric wards. No systematic analysis has been done of the safety of these teams in terms of rates of suicide. We aimed to compare the rate and number of suicides among patients under the care of crisis resolution home treatment teams with those of psychiatric inpatients. We also assessed the clinical features of individuals who died by suicide in both home and hospital settings.
  
  
  METHODS
  We did a retrospective longitudinal analysis between 2003 and 2011 of all adults (aged 18 years or older) treated by the National Health Service in England who died by suicide while under the care of crisis resolution home treatment services or as a psychiatric inpatient. We obtained data from the National Confidential Inquiry into Suicide and Homicide by People with Mental Illness and from the Mental Health Minimum Dataset.
  
  
  RESULTS
  1256 deaths by suicide (12% of all patient suicides) were recorded among patients cared for under crisis resolution home treatment teams, an average of 140 deaths per year. Different denominators meant that direct comparison between groups was difficult, but the average rate of suicide under crisis resolution home treatment services (14·6 per 10 000 episodes under crisis care) seemed higher than the average rate of suicide among psychiatric inpatients (8·8 per 10 000 admissions). The number of suicides in patients under the care of crisis resolution home treatment teams increased from an average of 80 per year (in 2003 and 2004) to 163 per year (in 2010 and 2011) and were twice as frequent as inpatient suicides in the last few years of the study. However, because of the growing number of patients under the care of crisis resolution home treatment teams, the average rate of suicide fell by 18% between the first and last 2 years of the study. 548 (44%) patients who died by suicide under the care of crisis resolution home treatment teams lived alone and 594 (49%) had had a recent adverse life event. In a third of patients (n=428) under the care of crisis resolution home treatment teams, suicide happened within 3 months of discharge from psychiatric inpatient care.
  
  
  CONCLUSIONS
  Although the number of suicides under the care of crisis resolution home treatment teams has risen since 2003, the rate has fallen. However, suicide rates remain high compared with the inpatient setting, and safety of individuals cared for by crisis resolution home treatment teams should be a priority for mental health services. For some vulnerable people who live alone or have adverse life circumstances, crisis resolution home treatment might not be the most appropriate care setting. Use of crisis resolution home treatment teams to facilitate early discharge could present a risk to some patients, which should be investigated further.
