The influence of perceived stress and musculoskeletal pain on work performance and work ability in Swedish health care workers

Abstract

ObjectivesTo evaluate the influence of perceived stress and musculoskeletal ache/pain, separately and in combination, at baseline, on self-rated work ability and work performance at two-year follow-up.MethodsSurvey data were collected with a 2-year interval. Health care workers participating at both waves were included. Inclusion criteria were good self-reported work ability and unchanged self-rated work performance at baseline, resulting in 770 participants; 617 women and 153 men. Musculoskeletal pain was assessed using the question “How often do you experience pain in joints and muscles, including the neck and low back?”, perceived stress with a modified version of a single item from the QPS-Nordic questionnaire, work performance by the question “Have your work performance changed during the preceding 12 months?” and work ability by a single item from the work ability index. Associations between baseline data and the two outcomes at follow-up were analysed by means of the log binomial model and expressed as risk ratios (RR) with 95 % confidence intervals (CI).ResultsA combination of frequent musculoskeletal pain and perceived stress constituted the highest risk for reporting decreased work performance (RR 1.7; CI 1.28–2.32) and reduced work ability (RR 1.7; CI 1.27–2.30) at follow-up. Separately, frequent pain, but not stress, was clearly associated with both outcomes.ConclusionThe results imply that proactive workplace interventions in order to maintain high work performance and good work ability should include measures to promote musculoskeletal well-being for the employees and measures, both individual and organizational, to minimize the risk of persistent stress reactions.

“Blue flags”, development of a short clinical questionnaire on work-related psychosocial risk factors - a validation study in primary care

“…Frequent neck/back pain combined with stress is associated with a high risk for reduced work ability [7]. Health, work and sick leave are all interrelated and low level of adjustment latitude at work can be a risk factor for sick leave [8–10].…”

Nature-Based Stress Management Course for Individuals at Risk of Adverse Health Effects from Work-Related Stress—Effects on Stress Related Symptoms, Workability and Sick Leave

“…The sources of stress are often to be found in increased demands, time pressure and worries connected to work, as well as to stressors in one’s private life, and are of prolonged character [7]. Effects of occupational stress can be absenteeism at the workplace and reduced work performance, connections reported in several studies [6,8,9]. …”

Psychosomatic symptoms and stressful working conditions among Palestinian nurses: a cross-sectional study

“…High levels of work stress among nurses may result in increasing job-related accidents, late arrivals and absence of work, and may thus result in decreased productivity and responsibility (Lee & Wang, 2002) and may affect the nurses’ professional efficiency, which might reduce the quality of patient care (Kane, 2009; Kawano, 2008; Lindegård, Larsman, Hadzibarjramovic, & Ahlborg, 2014; Sherman, 2004). Health care staff are being faced with increasing pressure, and emotional exhaustion scores were high among Hungarian health care staff included nurses (Pikó, 2006).…”
