Hip Fractures in Chile: Implications for Public Health Policy and Healthcare Delivery

Hip fractures in individuals aged 60 and above pose significant challenges in terms of morbidity, mortality, and healthcare costs. While countries like the United Kingdom and Australia have optimized their healthcare systems for timely management of hip fractures, the situation in Chile presents distinct challenges due to its mixed healthcare system. This study aims to assess survival rates following hip fractures in Chile and identify associated risk factors using national databases from 2012 to 2018. A comprehensive analysis of 35,520 patients revealed that factors such as age, type of health insurance, access to surgery, and treatment in public hospitals significantly influence mortality rates after hip fractures. The study found that patients with hip fractures experience lower 5-year survival rates compared to the general population, particularly when affiliated with public insurance and treated in public institutions. Modifiable factors like delayed surgery and prolonged hospital stays contribute to increased mortality rates. The findings underscore the urgent need for optimized public health policies and healthcare delivery systems to enhance outcomes for hip fracture patients in Chile.Hip fractures in individuals aged 60 and above pose significant challenges in terms of morbidity, mortality, and healthcare costs.

Study Population

The chilean national database of hospital discharge and the chilean death registry from 2012 to 2018 were used. , The date of death was recorded for the 35,520 patients who had deceased; otherwise, they are classified as alive as of the current date. We remark that the national discharge and death databases use the same patient IDs, and therefore, we can easily identify those patients who have died during the period under analysis. We notice that we have used the hospital discharge database up to 2017 to have at least one year of follow-up for patients after a hip fracture.

Description

Inclusion Criteria:

All patients in the national database between 2012 and 2017 which his principal was hip fracture. Diagnoses are classified using the International Classification of Diseases, 10th Revision (ICD-10) codes. A search was conducted for codes S72.0 (head and neck fracture of the femur), S72.1 (pertrochanteric fracture), and S72.2 (subtrochanteric fracture of the femur).

Exclusion Criteria:

missing IDs ID with inconsistent socio-demographic information. Patients with primary diagnosis of hip fracture that underwent surgery but the national code surgery was not one of the following: : 2104128, 2104129, 2104131, 2104132, 2104135, 2104228, 2104229 and 2104231
