Are there associations between caregiver information and suicidal behavior in psychiatric inpatients?

OBJECTIVE

The study aimed at exploring associations between inpatient suicides/attempted suicides in a psychiatric hospital and involvement of family caregivers in treatment.

METHODS

Based on the German psychiatric basic documentation systems (DGPPN-BADO), we analyzed a total sample of 49,257 cases of inpatient care (1998-2007) from a large psychiatric tertiary care university hospital and as a subsample all cases of schizophrenia, depression, acute stress/adjustment disorders and personality disorders (n = 22,880). Involvement of family caregivers was evaluated according to the following variables: admission to hospital due to recommendation of caregiver, conversation between therapist and caregiver, psychoeducation of caregiver as well as psychopharmacological and/or psychotherapeutic non-compliance of patient. Descriptive and bivariate analyses were performed.

RESULTS

Of the 22,880 cases in the subsample, 31 inpatient suicides and 198 attempted inpatient suicides were recorded. We could not find any significant associations of caregiver involvement variables with inpatient suicide. In contrast, for the total sample (n = 49,257), attempted suicide was associated with more conversation between therapists and caregivers (χ(2) = 3.863, df = 1, p = 0.049) and with psychopharmacological (χ(2) = 4.822, df = 1, p = 0.028) and psychotherapeutic (χ(2) = 13.041, df = 1, p = 0.000) non-compliance of the patients.

CONCLUSION

Further research is needed regarding the influence of caregivers on suicidal behavior of mentally ill inpatients.
