CD4 lymphocyte count as an indicator of delay in seeking human immunodeficiency virus-related treatment.
BACKGROUND
As many as half of patients infected with the human immunodeficiency virus who are medically eligible for Pneumocystis prophylaxis and zidovudine treatment have not received these treatments. We used the CD4 lymphocyte count as an indicator of delay in seeking treatment among patients infected with human immunodeficiency virus and assessed whether insurance status was associated with the stage of illness when care is initiated.


METHODS
Data from 96 patients who initiated medical care at a university acquired immunodeficiency syndrome clinic from August 1989 to January 1991 were retrospectively reviewed.


RESULTS
Patients initiated care at a relatively late stage of illness (mean CD4 lymphocyte count, 0.37 x 10(9)/L [369/mm3]), and 29% were below the threshold for Pneumocystis prophylaxis. Patients with private insurance had significantly lower CD4 counts (mean, 0.27 x 10(9)/L) than did individuals with public insurance (mean, 0.46 x 10(9)/L). CD4 counts did not increase during the 18-month study period.


CONCLUSIONS
The majority of patients infected with human immunodeficiency virus are eligible for medical therapy and could benefit by initiating care sooner. Private insurance was not associated with initiating early care, supporting anecdotal reports that some privately insured individuals may be reluctant to seek care for a human immunodeficiency virus-related condition.
