Causes, treatment and prevention of suicide

Abstract

BackgroundPatients with psychiatric disorders have a high rate of suicide. The present study investigated factors influencing hospital stays for Japanese patients with psychiatric disorders attempting suicide by jumping.

MethodsWe diagnosed all suicide attempts n = 113 by jumping based on the International Classification of Diseases 10th Revision ICD-10 and investigated the mean hospital stays of patients with each diagnosis based on the ICD-10 code. We then analyzed differences in the demographic and clinical characteristics between the diagnostic groups to identify factors influencing the duration of hospital stay.

ResultsPatients diagnosed with schizophrenia F2 code were the most frequent 32.7% of all diagnoses; therefore, we divided the diagnostic groups into schizophrenia group n = 37 and other psychiatric diagnoses group n = 76. The patients with schizophrenia showed a significantly longer hospital stay 125.7 ± 63.9 days compared with the patients with other psychiatric diagnoses 83.6 ± 63.2 β ± SE = 42.1 ± 12.7, p = 0.0013, whereas there was no difference in the jump height between the two groups the average was the 3rd to 4th floor; p > 0.05. The number of injured parts, particularly lower-limb fractures, was significantly higher p = 0.017 in patients with schizophrenia than in patients with other psychiatric diagnoses. The duration of psychiatric treatment in patients with schizophrenia were significantly longer z = 3.4, p = 0.001 than in patients with other psychiatric diagnoses.

ConclusionOur findings indicate that the number of injuries and the body parts injured in patients with schizophrenia are associated with a longer duration of hospital stay following a suicide attempt by jumping. The current use of antipsychotics and a longer duration of taking antipsychotics might contribute to the risk of bone fracture via hyperprolactinemia. Further cognitive impairment in patients with schizophrenia might prevent rehabilitation for the management of lower-limb fractures. From these results, we suggest that clinicians should monitor the level of prolactin and cognitive function in patients with schizophrenia in future studies on managing of lower-limb fractures.
