Physiological Changes Associated with Downsizing of Personnel and Reorganisation in the Health Care Sector

BACKGROUND: The objective of this study was to assess potential physiological changes associated with downsizing/reorganisation in the health care sector. The personnel reductions (1995-1997) in the studied regional hospital corresponded to one fifth of the personnel. METHODS: In a longitudinal study, female personnel had blood sampled twice (8 a.m. and 4 p.m.) during a working day in 1997 (in connection with the last completed round of personnel redundancies) and 1 year later in 1998. The participants were 31 women (82% of those initially sampled ); there were 14 registered nurses, 11 assistant nurses and 6 medical secretaries. No additional drop outs took place during follow-up. Outcome variables were changes in the difference in serum cortisol levels between the morning and afternoon and in serum/plasma concentrations of immunoglobulin G (IgG), oestradiol, dehydroepiandrosterone sulphate (DHEAS), prolactin and apolipoproteins AI and B. RESULTS: Significantly decreased serum/plasma concentrations of IgG (p < 0.001), apolipoprotein AI (p < 0.001) and oestradiol (p < 0.001) were found. The difference between morning and afternoon serum cortisol decreased, with a change at the significance level of p = 0.05. No significant changes were observed regarding prolactin, DHEAS and apolipoprotein B. CONCLUSIONS: These results could be an indication that protective and anabolic functions had suffered in these remaining 'ageing' female work groups. The circadian cortisol rhythm was possibly flattened, which could be a sign of physiological dysfunction associated with the long-lasting adaptation process. These conclusions are tentative, given the small size of the sample and the lack of a control group. However, the findings point to the significance of studies of physiological changes possibly associated with restructuring of the health care sector.
