ABSTRACT
Objective To learn the current status of job burnout and influencing factors for nurses from infectious disease hospital.Methods The Chinese version MBI -HSS was used to survey 218 nurses from infectious disease hospital,and linear regression was used to analyze the influencing facters of job burnout.Results A total of 210 questionairs were cocleted.The incidence of severe occupational job burnout was 22.38%,and the score of emotional exhaustion (EE), depersonalization (DP),personal accomplishment (PA)was(22.82 ±9.98),(6.48 ±5.20),and (35.20 ±8.82), respectively.Regression analysis demonstrated that the main influencing factors were entering the isolation ward, opportunity for infectious diseases ,disinfection damage,fear of occupational exposure and concern on family infection(P <0.05).Conclusion The status of job burnout of nurses in infectious disease hospital is not optimistic.There is a positive relationship with the working environment,occupational exposure.Managers need to explore an effective way to ease the job burnout of nurses,and to stabilize the nursing team.
ABSTRACT
<p><b>OBJECTIVE</b>To determine whether there was excessive risk of cancer among workers exposed to chrysotile fiber alone by applying a meta-analysis technique.</p><p><b>METHODS</b>All data meeting the criteria of cohort studies on cancer mortality among workers exposed only to chrysotile were incorporated into meta-analysis. Pooled standardized mortality ratios (SMRs) and their corresponding 95% confidence intervals (CIs) for main cancer sites were calculated using two approaches of unweighted ratio and random effect model. The heterogeneity and its sources of the results were examined with a Q-statistic and Z-score test. The dose-response effect as reflected in the percentage of all deaths due to mesothelioma served as a proxy measure of chrysotile exposure.</p><p><b>RESULTS</b>A cohort of twenty six workers exposed to chrysotile alone was summarized. The significantly elevated meta-SMRs for all deaths (1.27), all cancers (1.28), cancers of respiratory organs (2.51), cancers of lung (2.35) and cancers of stomach (1.24) were observed. The significantly elevated meta-SMRs for lung cancer within occupational strata were observed among textile workers (3.55), asbestos product manufacturers (3.30), miners and millers (2.24), cement product workers (1.22), and for stomach cancer among asbestos product manufacturers (1.49). Meta-SMRs for cancers at other sites were not significant. Meta-SMR for lung cancer showed an increasing trend with an elevated percentage of all deaths from mesothelioma, but no such trend for stomach cancer.</p><p><b>CONCLUSION</b>There are excessive risks of lung cancer and mesothelioma among workers exposed to chrysotile fiber alone, and likely no convincing indication of an etiological association between chrysotile exposure and cancers at other sites.</p>
