Analysis of a population-based Pneumocystis carinii pneumonia index as an outcome measure of access and quality of care for the treatment of HIV disease.

OBJECTIVES

A population-based Pneumocystis carinii pneumonia (PCP) Index was developed in New York City to identify geographic areas and subpopulations at increased risk for PCP.

METHODS

A zip code-level PCP Index was created from AIDS surveillance and hospital discharge records and defined as (number of PCP-related hospitalizations)/(number of persons living with AIDS).

RESULTS

In 1997, there were 2262 hospitalizations for PCP among 39 740 persons living with AIDS in New York City (PCP Index =.05691). PCP Index values varied widely across neighborhoods with high AIDS prevalence (West Village =.02532 vs Central Harlem =.08696). Some neighborhoods with moderate AIDS prevalence had strikingly high rates (Staten Island =.14035; northern Manhattan =.08756).

CONCLUSIONS

The PCP Index highlights communities in particular need of public health interventions to improve HIV-related service delivery.
