  1. Coronary revascularisation : why do rates vary geographically in the UK ?

    Article - En anglais


    To explain the reasons for geographical variation in the use of coronary revascularisation in the United Kingdom.


    This was a cross sectional ecological study.


    NHS and independent hospitals performing coronary revascularisation for the 11.6 million residents of the south east Thames, East Anglian and north western health regions in England plus Greater Glasgow, Lanarkshire, Ayr and Arran health boards in Scotland were included.


    All residents aged =25 years in 1992-93 who underwent coronary artery bypass grafting (CABG) or percutaneous transluminal coronary angioplasty (PTCA) in either the public or private sector were included.

    Main measures

    Crude and age-sex standardised intervention rates for residents of the 42 constituent districts and boards were determined.

    Variation was measured using the systematic component of variation.


    Considerable systematic variations in district rates of CABG and PTCA existed.

    These variations mostly arose from differences in supply factors.


    If greater geographical equity of use for the same level of need is to be achieved, attention must be paid to the supply factors that determine levels of utilisation.

    As responsibility for purchasing these procedures is decentralised, utilisation might become even more unequal.
