Equity of use of inpatient services by the two communities in Northern Ireland.
OBJECTIVE
There is concern about whether public services in Northern Ireland are equitably targeted across the religious divide. This study investigates whether use of acute hospital inpatient services differs by religious denomination, after adjusting for supply and for identified demographic, morbidity and socio-economic determinants of need for such services.


METHODS
Hospital utilisation at small area level was modelled against a wide range of potential health and socioeconomic factors. Spatial interactive modelling was used to estimate the effect of supply of hospital beds and other facilities on hospital utilisation. Two-stage weighted least-squares regression was used to model utilisation against need and supply.


RESULTS
There was a clear positive relationship between the proportion of Roman Catholics in a ward and both need for and utilisation of inpatient services. The higher levels of relative utilisation in wards with a greater proportion of Catholics persisted after controlling for needs but not when supply variables were also entered in the regression equation. The surviving needs drivers were: uptake levels of 'income maintenance' benefits, all-ages standardised mortality ratio, low birth weight and elderly people living alone. Most of these indicators of need are positively correlated with proportion of Catholics.


CONCLUSIONS
When both need and supply factors are taken into account, there appears to be no significant effect of religion on inpatient hospital use in Northern Ireland. Efforts to ensure socio-economic equity between the two communities should focus on ensuring that hospital rationalisation does not lead to disadvantage and on reducing socio-economic differentials between the Catholic and Protestant communities.
