Effect of two French nurses' strikes on mortality in a geriatric hospital.
OBJECTIVE
To study the influence of the 1988 French nurses' strikes on mortality in a geriatric hospital.


METHODS
Two nurses' strikes affected the Charles Foix Hospital near Paris from June 29 to July 31 and from September 17 to October 22, 1988. Mortality was studied in nine geriatric wards of this hospital, including two rehabilitation units comprising 187 beds, and seven long-term care units comprising 1,132 beds. Monthly mortality rates were calculated from the hospital's administrative registers and expressed as deaths per 1,000 patient-days. These rates were calculated in each of the aforementioned nine units for the 36 months preceding the first strike (control period) and for the 12 months following it (study period).


RESULTS
Over the control period, monthly mortality was significantly higher in rehabilitation units than in long-term care units (2.46 +/- 1.21 versus 0.83 +/- 0.47, p less than 0.001), but mortality rates among rehabilitation units, as well as among long-term care units, were comparable. Also, during the control period, large seasonal fluctuations in monthly mortality rates were observed in both rehabilitation units and long-term care units (peak in winter and nadir in summer). These rates tended to decrease from year to year in rehabilitation units but not in long-term care units. A statistical model based on time-series analysis of the control period data was used to calculate the expected monthly mortality rates for the study period in rehabilitation units and in long-term care units, respectively. Three of the 12 actual monthly mortality rates exceeded the upper limit of the 95% confidence interval of the 12 expected monthly mortality rates, in the units where the more severe care disruption occurred. A detailed analysis of discharge summaries of these units failed to identify a possible link between some of these deaths and a possible absence of care.


CONCLUSIONS
The nurses' strikes did not induce a clear-cut increase in mortality in this population of elderly patients. However, we cannot exclude the possibility that these strikes had some negative effects on health. Our results fail to provide answers to the difficult ethical problems created by such stoppages.
