Hospital Admission Profile Due to Osteoarthritis: An Ecological Study.

Background Osteoarthritis (OA) is also known as degenerative joint disease and is considered the major cause of joint pain and disability. Furthermore, OA is the most common, costly, and disabling form of joint diseases. The objective of this study is to explore the hospital admission profile due to OA between the period 1999 and 2019 in England and Wales. Method This is an ecological study that used health care data in the United Kingdom. Patients who were hospitalized for OA in England and Wales between 1999 and 2019 formed the study population. The Hospital Episode Statistics in England and the Patient Episode Database for Wales databases were used in this study. The difference in the admission rate during the study period was estimated using the chi-squared test. Results The admission rate during the study period increased by 112.1% for all hospital admission related to OA. The most common type of admission was related to gonarthrosis, which accounted for 46.7% of the total number of admissions for OA. The increase in admission rate across different types of admissions related to OA was not consistent. The highest increase in the admission rate was observed for polyarthrosis (604.6%). Admission rates related to OA were observed to be directly related to age. The highest increase in the admission rate during the study period was for the age group of 15-59 years (102.1%). Admission rate due to OA was higher among females compared to males. Conclusion The increase in admission rates for the various OA-related admissions was not consistent. This study found that the age range of 15 to 59 years experienced the greatest increase in admission rates. Female gender is a high risk factor for OA, especially in women around menopause.
