Work-system risk factors for permanent work disability among home-care workers: a case-control study

Area of Science:

• Occupational Health
• Public Health
• Sociology

Background:

• Home-care services are increasingly vital in Western societies.
• High rates of absence due to poor health among home-care workers necessitate understanding contributing factors.
• This study investigates work system impacts on permanent work disability in this sector.

Purpose of the Study:

• To explore and quantify the influence of the work system on permanent work disability among home-care workers.
• To compare the relative importance of work system risks versus home-life risks for disability.
• To identify specific occupational factors contributing to long-term work inability.

Main Methods:

• A case-control study design was employed.
• Cases comprised 617 home-care workers who received disability pensions in Sweden (1997-1998).
• Controls included 771 home-care workers who remained employed, with data collected via questionnaire on work and home life 5 and 15 years prior.

Main Results:

• Key work system risk factors included poor ergonomics/lifting, time pressure, and inadequate caring techniques.
• Work-related factors like insufficient management and relational issues (15 years prior) and poor organizational support (5 years prior) were significant.
• Home-life factors, particularly limited rest opportunities, were also risks, but work system factors demonstrated robustness and greater impact.

Conclusions:

• Work system risk factors are independently strong predictors of permanent work disability in home-care workers.
• Increased exposure to multiple occupational risk factors significantly elevates the risk of permanent work disability.
• Interventions targeting workplace conditions are crucial for preventing long-term disability in this essential workforce.
