Protecting the protectors: Occupational burden and management of work-related musculoskeletal disorders among Cameroonian healthcare professionals and the Sustainable Development Goals

Work-related musculoskeletal disorders (WRMSDs) constitute the primary occupational health burden among healthcare professionals (HCPs) globally and directly threaten health workforce sustainability, a critical concern for Sustainable Development Goal 3 (Good Health and Well-being) and SDG 8 (Decent Work and Economic Growth). Despite high prevalence in Cameroon, downstream occupational effects and management strategies across hospital levels remain undocumented. A hospital-based, analytical cross-sectional study was conducted across five referral hospitals in Douala, Cameroon (2019-2022). A total of 561 HCPs were enrolled by stratified random sampling. The Modified Nordic Musculoskeletal Questionnaire and structured interviews assessed WRMSD occupational effects and management strategies. Data were analysed using IBM SPSS v26; chi-square tests and logistic regression assessed associations (p < 0.05). The 12-month WRMSD prevalence was 83.4% (468/561). WRMSDs caused absenteeism in 83.4% of affected HCPs ({chi}2 = 14.414; p < 0.001), reduced daily activity capacity in 55.6%, and job dissatisfaction in 60.4%; 38.9% were considering a career change. Management was predominantly reactive: fitness training (76.3%), rest (41.4%), and non-steroidal anti-inflammatory drugs (NSAIDs; 37.3%). Only 15.0% received physiotherapy referral, and no hospital had a formal WRMSD protocol. WRMSDs impose a substantial and measurable occupational burden on HCPs in Douala. Current management is reactive, non-standardised, and under-integrated with physiotherapy. Evidence-based, multicomponent prevention programmes, physiotherapy integration, and a national occupational health policy are urgently required to protect the healthcare workforce and advance SDG 3 and SDG 8 targets in Cameroon.
