Burden of Chronic Musculoskeletal Disorders amongst Patients Attending Orthopaedic Outpatients Clinic of a Tertiary Hospital, North-Western Nigeria.

BACKGROUND
Musculoskeletal disorders often pose significant limitation to activities of daily living due to pain or disability. These disorders often arise as a result of the normal aging process, but most have some predisposing factors that are lifestyle-related, especially in younger people as a result of repeated mal- posturing/ misuse of parts of the body in the course of their jobs or recreations. These disorders cause more functional limitations in the older adult population than any other group of disorders. Thus, with increasing aging of most populations of the world, it is expected that the burden of these disorders will continue to rise. There is paucity of epidemiological data on this subject and no published study showing the ease of affordability of treatment for these conditions in Nigeria, hence this study.


PATIENTS AND METHODS
A cross -sectional study of patients with chronic musculoskeletal conditions attending the orthopaedic outpatient clinic of Ahmadu Bello university Teaching Hospital between 1st July 2019 and 31st December 2019, involving physical interview of new patients and review of case notes of old patients seen within the period. Statistical analysis was done with the Statistical Package for the Social Sciences (SPSS) version 20.0, and descriptive statistics were employed to summarize data. Pearson Chi- square test was used to examine for association between age, occupational ergonomic factors and chronic musculoskeletal conditions.


RESULTS
Forty-six percent of the outpatients suffered from chronic musculoskeletal disorders. Chronic low back pain accounted for the greatest burden (64.9%), followed by osteoarthritis of the weight bearing joints (27%), chronic neck pain (4.8%) and rheumatoid arthritis (2.8%). 51.8% of the patients with chronic low back pain, 64.5% of chronic neck pain and 68.5% of osteoarthritis were in the middle-age group. Occupational ergonomic factors as an entity was a significant risk factor identified in almost all the conditions except rheumatoid arthritis (P = 0.0001). Only 121(18.7%) of the patients enjoyed health insurance, while majority do not. Also, 56.0% of the patients had the means of footing the cost of their treatment (either by way of health insurance coverage or out-of-pocket payment).


CONCLUSION
The burden of chronic musculoskeletal disorders is high in our region. There is a need for the government to organize ergonomic educational programs through seminars and workshops as part of public health education, and a wider, well funded health insurance policy that covers both the formal and informal sectors and the full extent of the management of these chronic disorders to make such care accessible to all.
