The length of stay and how many times a patient has received three clinical tests were examined especially in inpatients with 4 surgical operations in this study. This study tries to find out the factors affecting the utilization of medical services. The subjects were inpatients who where discharged from a general hospital from January to June 1981 and from January to June 1982 and underwent 4 surgical operations which were Thyroidectomy, Lens Extraction, Hysterectomy and Cesarean Section.
The percentage of patients who stayed longer than 4o days with Thyroidectomy of Lens Extraction or Hysterectomy and patients who stayed longer than 30 days with Cesarean section were 1.4% of all patients with 4 surgeries. These patients with extraordinarily long days stay were excluded in this study.
The results are as follows;
Ⅰ. The average length of stay of patients with Thyroidectomy, Lens Extraction, Hysterectomy and Cesarean Section were 11.48 days, 12.69 days, 16.25 days and 10.77 days respectively.
The percentage of the patients with length of stay within normal range (x ± 2SD) were 95% of all inpatients examined.
Ⅱ. Patients with medical insurance stayed a slightly longer period than do the self-pay patients, but the statistical differences were insignificant. Medical protection patients and teaching patients stayed longer than medical insurance patients and self-pay patients.
Ⅲ. There were little changes in length of stay by sex.
Ⅳ. Patients from other regions stayed a little longer than patients who live in Seoul.
Ⅴ. Old patients were found to stay longer than younger patients.
Ⅵ. Patients with medical insurance received more clinical tests than self-pay patients. Medical protection patients and teaching patients took more clinical tests than patients with medical insurance and self-pay patients.
Number of times of clinical tests carried out for patients with medical insurance and self-pay patients increased by year. Number of times of clinical tests taken by medical protection patients or teaching patients were irregular.
The longer stays and the more tests for both medical protection patients and teaching patients may indicate that these patients are in poorer health and that they have less chances of medical services.
