<b>Factor Associated with Work-Related Musculoskeletal Injuries Among Health Care Professionals Working in the Operation Room at Shaukat Khanum Cancer Memorial Hospital and Research Center</b>

Background: Work-related musculoskeletal injuries (MSIs) represent a significant occupational hazard among healthcare professionals, particularly those working in operating rooms (OR), where prolonged static postures, repetitive movements, and high physical demands increase the risk of musculoskeletal disorders, potentially compromising worker health and patient care quality. Objective: This study aimed to assess the occurrence and severity of MSIs among OR healthcare professionals at Shaukat Khanum Memorial Cancer Hospital and Research Center and to determine associations between MSIs and demographic and occupational factors. Methods: An observational analytical study was conducted over four months among OR staff, employing universal sampling. Data were collected via a structured, validated questionnaire capturing demographics, work tasks, and MSI symptoms across various body regions. Statistical analyses, including Chi-square tests and calculation of odds ratios, were performed using SPSS version 20 to examine associations between MSIs and demographic or occupational factors, with significance set at p < 0.05. Results: MSIs were reported by 40% of participants, with the upper back (46.5%), neck (33.5%), and wrists/hands (23.5%) most frequently affected. Significant associations were observed between MSIs and age (p=0.015), profession (p=0.011), work experience (p=0.003), patient lifting (p=0.021), instrument retraction (p=0.047), and poor posture during procedures (p=0.001). Conclusion: High MSI prevalence among OR staff underscores the need for ergonomic interventions and training programs to reduce occupational injuries and enhance healthcare workforce sustainability and patient safety.
