전·후기 노인 손상환자의 재원일수 결정요인: 퇴원손상심층자료를 이용하여

This study was conducted to provide essential baseline data that underscores the importance of injury prevention, treatment, and control in older adults. To achieve the aim of the study, characteristics of lengths of hospital stay in the young-old and old-old patients with injuries were analyzed by using the data from the Korea National Hospital Discharge In-Depth Injury Surveys(2018-2022). 49,417 patients aged 65 and over, who participated in the Korea National Hospital Discharge In-Depth Injury Surveys, got a principal diagnosis of injury, poisoning, and certain other consequences of external causes(S00-T99), and were discharged between 1 January 2018 and 31 December 2022, were investigated. To determine the general characteristics of the patients, a frequency analysis was performed. Additionally, t-tests and ANOVA were used to determine differences in length of stay in patients based on the patients’ sociodemographic characteristics. Also, to identify determinants of length of stay, a regression analysis was performed. According to the results of the study, the average length of stay was 15.8 days. The lengths of stay for the old-old patients was higher than that for the young-old patients and the patients, who had either public or private coverage, had longer hospital stays than the others. The length of stay for the patients, who were admitted to a hospital in a rural area or a hospital that had less than 500 hospital beds, was higher than that for the other patients. However, the patients who were transferred from the emergency department or injured in traffic crashes stayed longer in hospital. The length of the stay of the patients who got a secondary diagnosis or had a principal procedure was higher than that of the others. Also, the patients who were transferred to another hospital had longer hospital stays than the others. The differences between the lengths of hospital stay found in all those cases except for the difference made by what happened to the patients discharged were statistically significant. The present study shall be useful since it has provided essential baseline data that underscores the importance of injury prevention, treatment, and control in older adults by using the data from a national survey, or more specifically, the Korea National Hospital Discharge In-Depth Injury Survey.
