Analysis of demographic and clinical characteristics of elderly inpatients with osteoporotic femoral neck fractures / 中华老年医学杂志

ABSTRACT

Objective:To analyze the demographic and clinical characteristics of elderly inpatients with osteoporotic femoral neck fractures(OFNF).Methods:Clinical data of 1 227 patients with OFNF treated at the department of orthopedics of Beijing Hospital from January 2010 to December 2019 were analyzed retrospectively, including 377 male and 850 female patients.Ten-year trends in the OFNF constituent ratio, patient age, average length of stay and hospitalization expenses were examined, and differences in demographic and clinical characteristics between different genders were analyzed.Results:From 2010 to 2017, the constituent ratio of OFNF patients increased each year, and the number of OFNF patients decreased slightly in 2018 and 2019.The age of onset in both male and female patients was the highest at the ages of 80-89(46.8% or 574/1 227). In the distribution of educational level, people with no education made up the highest proportion(36.7% or 450/1 227). The seasonal distribution of the disease was the highest in autumn(27.8% or 341/1 227). The constituent ratio of urban areas was higher than that of rural areas(54.6% or 670/1 227 vs.45.4% or 557/1 227). In the distribution of fracture types, the constituent ratio of 31-B2 fractures was the highest in both male and female patients.Of the causes of injury, the constituent ratio of falls and indoor activities was the highest.Hypertension, spinal degenerative diseases and knee and hip osteoarthritis ranked in the top three of concomitant diseases.The constituent ratio of previous fractures in females was significantly higher than that in males.In the past ten years, the average hospitalization length of OFNF patients showed a downward trend, and the change in average hospitalization cost showed abrupt fluctuations.From 2009 to 2016, the hospitalization cost showed an upward trend, with the highest in 2016, and then decreased year by year. Conclusions:In the past ten years, the number and constituent ratio of OFNF patients increased steadily in the first eight years, but decreased slightly or reached a plateau in the past two years.The education level, history of bone fractures, hypertension, spinal degenerative diseases and knee and hip osteoarthritis of OFNF patients were correlated with sex, while age distribution, seasonal distribution, urban and rural distribution, cause of injury, fracture classification and other concomitant diseases were not correlated with sex.In the past ten years, the average hospitalization length of OFNF patients trended downward, the average hospitalization cost showed an upward trend from 2009 to 2016, and decreased year by year after 2016.The medical policy reform in 2016 played a significant role in controlling medical expenses.
