| Abstract: | Self-injurious behavior usually occurs among psychiatric patients.The incidence density of suicide and self-injurious behavior rank third in the patient safety reporting list of a psychiatric teaching hospital. The underlying reasons of self-injurious behavior are so complex that the consequence could be fatal. Nevertheless, domestic researches on self-injurious behavior are still quite few.One aim of this study was to understand the incidence trend and successful rate of self-injurious behaviors in patients of a psychiatric teaching hospital from Year 2009 to Year 2011. Furthermore, we intended to analyze the influencing factors, including patient characteristic, environmental, and caring aspects, of the consequence right after the self-injurious behaviors. The sample hospital provided totally 6,419 hospitalized patients data with 162 patients having self-injurious intention records as the sources of this research. Among the consequence of self-injurious behaviors, 77 injured, 85 didn’t. We employed SPSS (version 17.0) as our software to proceed statistical inferences.The results showed that there were 331 self-injurious behavior events. During Year 2009-2011, the self-injury incidence was decreasing from 7.56%, 5%, to 2.97%, while the self-injury successful rate was 36.5%, 46.3%, 40.3%, respectively. In addition, the only determinants on whether the self-injurious behaviors of hospitalized patients might be successful (i.e, injured) or not (i.e, not injured) was where the event taking place. In other words, the chance of successful self-injury in public area was significantly higher than that in private one. This study showed the figures, trend, and influencing factors of self-injury in a psychiatric teaching hospital during Year 2009-2011. Hopefully the findings could be a reference for a hospital to establish the threshold basis of monthly self-injury incidence densities, and for environmental monitoring by applying information technology network or by rescheduling nursing ward-watch to reduce patients’ self-injury successful rates. |
