Health care staff on psychiatric inpatient units are at high risk for work-related assaults by patients. Recent studies have begun to document similar patient assaults toward staff in community-based residences. Earlier community studies did not control for the level of patient assault prior to community discharge, and it remains unknown whether the community residence assaults were a function of community placement or a reflection of ongoing control issues by the recently discharged patients. This preliminary inquiry retrospectively tracked the nature and frequency of assaults by patients newly discharged to community residences from a state hospital setting where there had been no assaults by these patients for a two-and-one half-year period. While base rates remain to be determined, the findings in this study suggest the assaultive patients to be younger males with diagnoses of schizophrenia and histories of violence toward others, substance abuse, and violence toward self. Nine patients committed the majority of the assaults. There was a significant decline in the frequency of assaults nine months post-discharge. The implications are discussed.

The study examined assaultive behavior directed toward staff of community-based residential facilities by patients who had been discharged to these facilities from Massachusetts state psychiatric hospitals in the early 1990s. Observed rates of assault declined by 61 percent over a six-and-a-half-year period. Early in the study period, male patients were more likely than female patients to be assaultive, but men and women had similar rates of assaultiveness later in the study period, after they had been in residential placements for several years. The most common diagnosis among assaultive patients was schizophrenia.
