Abstract

Background: Carpal tunnel syndrome (CTS) is commonly reported among professional computer users. Repetitive work is a widely known risk factor for occupational CTS. Administrative staff for patient registration is one of the jobs in Dr. Soetomo General Hospital that deals with repetitive data entry work in terms of long-term use of computers. Objective: This study aims to determine the relationship between length of work and hand position of computer use with the incidence of carpal tunnel syndrome in administrative registration staff at Dr. Soetomo Hospital Surabaya. Method: Clinical examination and nerve conduction study (NCS) observes 60 hands of 30 registration officers with computer users at Dr. RSUD Dr. Soetomo Surabaya that fulfills the inclusion and exclusion criteria from period of the October-December 2012. Results: The average age of the study subjects was 37.80 + 10.841. The subjects of the study consisted of 54 women and 6 men. The average length of work in the year is 9.75 + 8.36. The average working hour / day is 6.02 + 1.367. The frequency of the most extension hand position with 68.3%, the incidence of 92.9% for the occurrence of CTS work duration> 3 years was significant with P = 0.005, RO 8,273 (95% CI 1,82937,410). The incident rate is 89.6%, for the occurrence of CTS at staff with working years > 4000 hours, gets result of P=0.021, RO 6.143 (95% CI 1.406-26,842). The incident of 87.8% for the occurrence of CTS with extended hand position, gets insignificant result with P = 0.263, RO 2.571 (95% CI 0.644-10.270). Conclusion: There was a significant relationship between length of work and the incidence of CTS and there was no relationship between extension hand position and incidence of CTS.
