The cytotechnologists perform the scrutiny of cytological samples using the optical microscope. They are often affected by Work-Related Musculoskeletal Disorders (WMSDs) due to excessive force, repetitive movements, bad posture, static posture or vibration during use of the microscope. In Brazil, there is no legal requirement for the number of slides that cytotechnologists must see throughout their workday. In this context, we sought to identify and quantify the repetitive activities performed by cytotechnologists of the Integrated Section of Technology in Cytopathology (SITEC) of the Division of Pathology (DIPAT) of the National Cancer Institute José Alencar Gomes da Silva (INCA) in the screening of cervicovaginal cytological preparations, to measure musculoskeletal symptoms and to seek opportunities for improvements in the work process, aiming at reducing injuries to professionals. We applied the Nordic Osteomuscular Symptoms Questionnaire for Cytotechnologists, we analyzed the disease records in the INCA Worker Health Division (DISAT) during the period from January 2016 to December 2017 and performed the counting of the reading time and movements in the charriot, fine focus knob, coarse focus knob and in the revolving nosepiece of the optical microscope was performed for five cytotechnologists during the reading of three conventional cytology slides and three liquid base cytology slides. The data obtained for analysis were organized into tables using the Statistical Package for the Social Sciences (SPSS). Based on the data from the questionnaire, 34.4% of the cytotechnologists reported withdrawal from work by WMSD and the main complaints were in the region of the cervical and lumbar spine. According to DISAT records, the main reasons for absenteeism among SITEC professionals were diseases categorized in the musculoskeletal and connective tissue diseases group (25%). There was a statistically significant relationship between Body Mass Index (BMI) and WMSDs absenteeism. We obtained an average of five hundred (500) touches and three (3) dorsal revolutions per slides by suming the movements in the charriot, fine focus knob, coarse focus knob, revolving nosepiece and dorsal rotation among all cytotechnologists, in the six cases. The average reading time of the conventional cytology slides was 278.4 seconds, while the mean cytology slides were 285.5 seconds. Long hours using the optic microscope and or improper posture during screening can generate musculoskeletal problems in cytotechnologists. Ergonomics awareness is critical for risk identification and planning for preventive measures. The evaluation of the quantitative of touches in the microscope is necessary for the definition of the workload minimizing the musculoskeletal discomforts associated with repetitive movements. The introduction of new technologies such as liquid-based cytology, which allows the automation of stages of its processing, should contribute to propose improvements on the workload of these professionals.
