  1. Annual league tables of mortality in neonatal intensive care units : longitudinal study.

    Article - En anglais


    To assess whether crude league tables of mortality and league tables of risk adjusted mortality accurately reflect the performance of hospitals.


    Longitudinal study of mortality occurring in hospital.


    9 neonatal intensive care units in the United Kingdom.


    2671 very low birth weight or preterm infants admitted to neonatal intensive care units between 1988 and 1994.

    Main outcome measures 

    Crude hospital mortality and hospital mortality adjusted using the clinical risk index for babies (CRIB) score.


    Hospitals had wide and overlapping confidence intervals when ranked by mortality in annual league tables ; this made it impossible to discriminate between hospitals reliably.

    In most years there was no significant difference between hospitals, only random variation.

    The apparent performance of individual hospitals fluctuated substantially from year to year.


    Annual league tables are not reliable indicators of performance or best practice ; they do not reflect consistent differences between hospitals.

    Any action prompted by the annual league tables would have been equally likely to have been beneficial, detrimental, or irrelevant Mortality should be compared between groups of hospitals using specific criteria-such as differences in the volume of patients, staffing policy, training of staff, or aspects of clinical practice-after adjusting for risk.
