Explicative factors of occupational stress among caregivers in hospitals in Brazzaville: a cross-sectional analytical study

INTRODUCTION: staff health represent a population particularly exposed to numerous psycho-social risks. The organization, pace and workload, as well as difficulties in terms of working equipment or personnel have been shown to be a source and consequences of work stress. The objective is to study the factors of stress experienced by health professionals working in district hospitals and to propose preventive actions to decision-makers. METHODS: a cross-sectional analytical study carried out among caregivers in the hospitalization services of Brazzaville. The relationship between stress and certain characteristics of the participants was established using single and multiple logistic regressions taking into account potential confounding factors. For this purpose, Wald Chi-square tests were used as well as the odds ratio with their 95% confidence interval. RESULTS: midwives have a higher probability of experiencing stress OR = 2.12 [1.13- 4.20] caregivers with less than 10 years of practice are less likely to experience work-related stress OR = 0.53 [0.28 - 0.96] than those with more than 10 years of practice, p = 0.040. After adjusting for possible confounding factors, caregivers who felt useful at work experienced about 5 times more stress odds ratio adjusted (ORa) = 4.69 [1.82 - 12.78] p = 0.002 than those who did not feel useful. CONCLUSION: the factors that influence stress among health workers are of a socio-professional nature, and related to the perception of working conditions. Some of them significantly increase the risk of experiencing work-related stress. Further studies are needed to better understand the consequences of occupational stress on the performance of caregivers.
