Background: Patients admitted to hospital at the weekend appear to be at increased risk of death compared with those admitted at other times. However, a 'weekend effect' has rarely been explored in mental health and there may also be other times of year when patients are vulnerable.
Aims: To investigate the timing of suicide in high-risk mental health patients.
Method: We compared the incidence of suicide at the weekend v. during the week, and also in August (the month of junior doctor changeover) v. other months in in-patients, patients within 3 months of discharge and patients under the care of crisis resolution home treatment (CRHT) teams (2001-2013).
Results: The incidence of suicide was lower at the weekends for each group (incidence rate ratio (IRR) = 0.88 (95% CI 0.79-0.99) for in-patients, IRR = 0.85 (95% CI 0.78-0.92) for post-discharge patients, IRR = 0.87 (95% CI 0.78-0.97) for CRHT patients). Patients who died by suicide were also less likely to have been admitted at weekends than during the week (IRR = 0.52 (95% CI 0.45-0.60)). The incidence of suicide in August was not significantly different from other months.
Conclusions: We found evidence of a weekend effect for suicide risk among high-risk mental health patients, but with a 12-15% lower incidence at weekends. Our study does not support the claim that safety is compromised at weekends, at least in mental health services.
