Musculoskeletal System and Connective Tissue Related Hospital Admission in England and Wales Between 1999 and 2019:...

Background There is a lack of data describing inpatient hospitalization trends for musculoskeletal and connective tissue diseases in the United Kingdom. Aim We aim to provide a comprehensive analysis of the trends of musculoskeletal and connective tissue disease related hospitalizations between 1999 and 2019 in England and Wales. Method We conducted an ecologic study. The data were obtained from the Hospital Episode Statistics database in England and the Patient Episode Database in Wales between 1999 and 2019. We used ICD-10 (International Classification of Diseases, 10th Revision) codes M00-M99 to identify hospital admissions. Results The total annual hospital admission rate increased from 1,303.63 (95% CI: 1,300.55-1,306.71) in 1999 to 2,479.09 (95% CI: 2,475.14-2,483.04) in 2019 per 100,000 persons (p<0.01). The ICD-10 categories other joint disorders, osteoarthritis, and other dorsopathies accounted for 19.6%, 19.6%, and 18.6% of hospitalizations, respectively. Advanced age groups experienced a larger increase in hospitalization rates (128.6% in the age group of 75 years and above vs. 45.9% in the age group below 15 years). Females contributed to 57.7% of hospitalizations and experienced a larger increase in hospitalization rate compared to males (103.8% vs. 73.8%). Conclusion Between 1999 and 2009, the hospitalization rate for musculoskeletal and connective tissue diseases has steadily increased in England and Wales. However, the rate has plateaued or declined in many of musculoskeletal and connective tissue diseases between 2010 and 2019. Due to the chronicity of these diseases, their significant morbidity, and significant long-term disability, national interventions are needed to mitigate the effects of the increased cost of treatment.
