  1. Explaining variation in hospital admission rates between general practices : cross sectional study.

    Article - En anglais

    Objectives To quantify the extent of the variation in hospital admission rates between general practices, and to investigate whether this variation can be explained by factors relating to the patient, the hospital, and the general practice.

    Design Cross sectional analysis of routine data.

    Setting Merton, Sutton, and Wandsworth Health Authority, which includes areas of inner and outer London.

    Subjects 209 136 hospital admissions in 1995-6 in patients registered with 120 general practices in the study area.

    Main outcome measures Hospital admission rates for general practices for overall, emergency, and elective admissions.

    Results Crude admission rates for general practices displayed a twofold difference between the 10th and the 90th centile for all, emergency, and elective admissions.

    This difference was only minimally reduced by standardising for age and sex.

    Sociodemographic patient factors derived from census data accounted for 42% of the variation in overall admission rates ; 45% in emergency admission rates ; and 25% in elective admission rates.

    There was a strong positive correlation between factors related to deprivation and emergency, but not elective, admission rates, raising questions about equity of provision of health care.

    The percentage of each practice's admissions to different local hospitals added significantly to the explanation of variation, while the general practice characteristics considered added very little. (...)
