3 The ICD-10 diagnosis code recorded at the time of the index detention was obtained from the individual's electronic notes, and whether or not they had a comorbid or secondary diagnosis of psychoactive substance use. Three individuals were removed from the follow-up analysis as they were found to be duplicates.Īdditional data were collected about the original cohort, including ICD-10 psychiatric diagnosis and outcome of the index S136 detention. The follow-up period was defined as 365 days from the index detention date as recorded in the notes. If the individual was detained multiple times during the data collection period, only the first detention was included in the analysis.
These 245 individuals presented to the South West London and St George's Mental Health NHS Trust place of safety between 1 February and 31 July 2012, after being detained under S136 of the Mental Health Act. In addition, it will investigate whether drug and alcohol intoxication was related to these outcomes.ĭata were retrospectively collected from the electronic notes of the original cohort. It will provide more detailed information about the outcomes of the original assessments, whether the cohort went on to use local mental health services, and explore the characteristics of the group of patients who present to services repeatedly. This study aims to follow-up the original cohort for 1 year after their detention. Being intoxicated was associated with a breach of the 6-hour assessment completion target and greater likelihood of being discharged home after assessment. The study also found that 44.9% of individuals were intoxicated with alcohol or drugs. The most common reason for detention was threat to self-harm, but after a Mental Health Act assessment over half were discharged home. More than half of the individuals had been previously detained under S136 or admitted to hospital. Reference Zisman and O'Brien2 Two-hundred and forty-five people were detained and brought to one S136 suite between February 2012 and July 2012. 1 Zisman & O’Brien sought to characterise individuals detained under S136 by conducting a retrospective cohort study over a 6-month period at a London mental health trust. The use of S136 has increased fourfold over the past 10 years, and 18% between 016. A place of safety is usually a unit within a psychiatric hospital (‘Section 136 suite’), a police station or an Accident and Emergency department, and the individual can be detained for up to 72 h for the purpose of conducting a Mental Health Act assessment. Section 136 (S136) of the Mental Health Act 1983 (amended 2007) allows police officers to remove an individual whom they believe to be mentally disordered and in ‘immediate need of care or control’ from a public place to a designated place of safety, ‘in the interest of that person or for the protection of other persons’.
