Carpal Tunnel Syndrome and Associated Factors among Healthcare Practitioners at Vaccine Centres in Saudi Arabia: A Cross-sectional Study

Abstract

Introduction: Carpal Tunnel Syndrome (CTS) presents with symptoms like numbness, tingling, and weakness along the median nerve pathway. Risk factors include prolonged wrist positions, repetitive muscle contractions, and exposure to vibrations. Aim: To determine the prevalence of CTS among healthcare practitioners at vaccine facilities in Saudi Arabia. Materials and Methods: A cross-sectional study on a total of 150 healthcare practitioners (aged 25-30 years) working in vaccination centres in Riyadh, Saudi Arabia were recruited. The study was conducted from November 2021 to March 2022. The authors collected demographic data, Body Mass Index (BMI) and work shift information, and administered two validated questionnaires, the Boston Carpal Tunnel Syndrome Questionnaire (BCTSQ) and the Duruoz Hand Index (DHI). CTS symptoms were diagnosed using Phalen’s and Arm Raising Test (ART). Results: Of the 150 practitioners (aged 25-45 years), predominantly in the 25-30 age group, n=65 (44.0%) tested positive on the Phalen’s test, and n=65 (43.5%) on the ART. Females had higher BCTSQ scores, while DHI scores were similar across genders. Spearman's correlation analysis showed positive correlations between BCTSQ and DHI, and a moderate negative correlation between ART and DHI. Logistic regression analysed factors affecting the likelihood of CTS diagnosed by ART and Phalen’s Test. Higher BCTSQ and DHI scores increased the likelihood of CTS (ART: BCTSQ OR=0.843, DHI OR=1.064; Phalen’s Test: BCTSQ OR=0.830, DHI OR=1.069). Conclusion: During the Coronavirus Disease-2019 (COVID- 19) pandemic, the prevalence of CTS among healthcare practitioners at vaccine centres in Riyadh, Saudi Arabia reached up to 43-44%. The present study highlights that day shift workers face a higher risk of CTS compared to night shift workers, likely due to heavier daytime workloads. This underscores the need for ergonomic interventions and workload management, especially during high-demand periods like the vaccination campaign, to safeguard healthcare workers’ health and productivity.
