RESUMO

Nursing personnel are at a high risk from work-related museuloskeletal disorders, espeeially baek symptoms. Handling patients has been attributed as one of the factors playing an important role in the aetiology of oeeupational low baek pain. The aim of the study was to develop an instrument to evaluate the ergonomie risks during patient-handling tasks, and to determine the validity and reliability of the instrument. The instrument was developed with an ergonomie approaeh. The instrument eonsists of 8 items: weight, height, eonseiousness and psyehomotrieity, mobility in bed, transfers, walking, catheters and equipments, and environment. In order to identify the risk analysis, the total seores were categorized into three levels: "Iow risk" (seore:8-12), "medium risk" (seore:13-18) and high risk (seore:19- 24). The validity of the instrument was established by evaluating eontent and eonstruct validity. The eonstruet validity was tested by two groups of patients in two different hospital units that were expeeted to have eontrasting seores on the instrument. The reliability evaluation was estimated through homogeneity, stability (test-retest) and equivalence (interrater). To evaluate reability, hospital nurses administered the instrument twice to the same subjeets under similar eonditions. In the first step of the validation process, a judge panel of experts was requested to determine if the instrument was appropriate and aeeurate. The findings demonstrated a statiscally significant diference between the two groups in different hospital units (Mann-Whitney = 0.0001 and Chi-square = 0.0001). Reliability estimated by internal eonsisteney reaehed a Cronbaeh s alpha of 0.81. Pearson s eorrelation eoeffieient for test-retest reliability was r = 0.92. The agreement between the same observers was excellent, aeeording to the k values (Kappa = 0.92). The interobserver (interrater) reliability was assessed by Pearson s correlation eoeffieient, reaehing an r-value of 0.84. The agreement between the registrations of two observers was also fairly good (Kappa = 0.84). The results of the eurrent study show that the instrument seems to be reliable and valid for assessing patient handling tasks. KewWords: Low baek pain. Handling patient. Ergonomies. Validity
