Effectiveness of Workplace Interventions to Improve Health and Well-Being of Health and Social Service Workers: A Narrative Review of Randomised Controlled Trials

Health and social service workers face high levels of workload and job stressors, which can affect their health and well-being. Therefore, it is important to evaluate the effectiveness of workplace interventions that aim to improve their mental and physical health outcomes. This review summarizes the findings of randomized controlled trials (RCTs) that examined the impact of different types of workplace interventions on various health indicators among health and social service workers. The review searched the PubMed database from its inception to December 2022 and included RCTs that reported on the effectiveness of organizational-level interventions and qualitative studies that explored barriers and facilitators to participation in such interventions. A total of 108 RCTs were included in the review, covering job burnout (N = 56 RCTs), happiness or job satisfaction (N = 35), sickness absence (N = 18), psychosocial work stressors (N = 14), well-being (N = 13), work ability (N = 12), job performance or work engagement (N = 12), perceived general health (N = 9), and occupational injuries (N = 3). The review found that several workplace interventions were effective in improving work ability, well-being, perceived general health, work performance, and job satisfaction and in reducing psychosocial stressors, burnout, and sickness absence among healthcare workers. However, the effects were generally modest and short-lived. Some of the common barriers to participation in workplace interventions among healthcare workers were inadequate staff, high workload, time pressures, work constraints, lack of manager support, scheduling health programs outside work hours, and lack of motivation. This review suggests that workplace interventions have small short-term positive effects on health and well-being of healthcare workers. Workplace interventions should be implemented as routine programs with free work hours to encourage participation or integrate intervention activities into daily work routines.
