ABSTRACT
Objective@#This study aimed at identifying the incidence rate and characteristics of patients who had suffered falls, classifying them by life cycle and factors that affect mortality. @*Methods@#The Korean National Hospital Discharge In-depth Injury Surveys (KNHDIS) from 2007 to 2016 were used to investigate the sex, age, place, season, payment method, underlying disease, and the death of hospitalized patients due to falls. @*Results@#The number of hospitalized patients increased with age. In all life cycles except old age, men were hospitalized more than women. The payment method for treatment was 66.1% through national health insurance, 6.6% through medical aid, and 27.3% through other sources. Falls were most common in winter and occurred frequently at home and on the road. In terms of the number of patients, the compound annual growth rate was 0.9% for men and 3.7% for women. In terms of the number of deaths in hospitals, the compound annual growth rate was -1.9% for men and -7.2% for women. Mortality risk was high in men in middle adulthood and old age, in patients with underlying diseases, and in patients who suffered a fall in their homes. @*Conclusion@#The number of patients from falls is increasing, but the deaths of hospitalized fall patients are decreasing. Mortality risk was high in men in middle adulthood and old age, in patients with underlying diseases, and in patients who suffered falls in their homes.

ABSTRACT
Background@#This study investigates the influence factors of medical service variations using medical charge and the length of stay (LOS) for urinary incontinence surgery and uterine polypectomy. @*Methods@#The National Health Insurance claims data and Medical Resource Report by the Health Insurance Review & Assessment Service in 2016 were used. Frequency analysis, one-way analysis of variance, and Bonferroni post-hoc tests were executed for each surgery. A multilevel analysis was executed to assess the factors to the medical charge and LOS for each surgery in patient, doctor, and hospital level. @*Results@#Fifty-two point eight percent of urinary incontinence surgery and 87.1% of uterine polypectomy were distributed in general and tertiary hospitals. Among three levels, the patient level variation was 61.5% or 77.2% in medical charge and 93.9% or 96.3% in LOS, respectively. The doctor level variation was 29.6% or 22.6% in medical charge and 0.6% or 0.0% in LOS, respectively. The institution level variation was 8.9% or 0.2% in medical charge and 5.5% or 3.7% in LOS, respectively. Number of other disease and organizational type were main factors that affected the charge and LOS for urinary incontinence surgery and uterine polypectomy. @*Conclusion@#Medical service variations of the urinary incontinence surgery and uterine polypectomy were the largest for the patient level, followed by doctor level for the medical charge, and the institution level for the LOS.
