摘要:To characterize injuries occurring in jails, we analyzed injury report forms from the New York City jail system. We abstracted data from 4695 injury report forms representing 3863 patients. Of the injuries reported, 66% were classified as intentional. The 2 leading causes of injuries were inmate-on-inmate aggression (40%) and slips and falls (27%). Injuries place a considerable burden on jail health care systems, and there is a need for more studies on this problem and development of injury prevention programs. Although inmate injuries place a considerable burden on both individuals and the jail health care system, there is little published research on the topic. 1–4 These injuries also have an impact on the communities to which inmates return and have been found to compound existing barriers to employment, education, housing, and substance abuse treatment, which can affect reintegration into the community and increase the likelihood of recidivism. 5–10 New York City has one of the largest jail systems in the United States, with more than 90 000 admissions annually and a daily inmate population of approximately 13 000. Inmates are in the custody of the New York City Department of Correction (DOC), and the New York City Department of Health and Mental Hygiene (DOHMH) is responsible for their health care. According to protocols developed by the 2 agencies, all inmates who are injured or suspected of being injured are taken to the jail clinic by the DOC for medical evaluation even if their injuries appear minor or if they intend to refuse treatment. We analyzed New York City jail system injury report data in an effort to gain a better understanding of the extent and nature of injuries occurring in jails.
