To determine whether older age continues to influence patterns of care and in-hospital mortality for hospitalized persons with HIV-related Pneumocustis carinii pneumonia (PCP), as determined in our prior study from the 1980s.
Retrospective chart review.
Patients (1,861) with HIV-related PCP at 78 hospitals in 8 cities from 1995 to 1997.
Medical record notation of possible HIV infection; alveolar-arterial oxygen gradient; CD4 lymphocyte count; presence or absence of wasting; timely use of anti-PCP medications; in-hospital mortality.
Compared to younger patients, patients ≥50 years of age were less likely to have HIV mentioned in their progress notes (70% vs 82%, P < .001), have mild or moderately severe PCP cases at admission (89% vs 96%, P < .002), receive anti-PCP medications within the first 2 days of hospitalization (86% vs 93%, P <.002), and survive hospitalization (82% vs 90%, P < .003). However, age was not a significant predicator of mortality after adjustment for severity of PCP and timeliness of therapy.
While inpatient PCP mortality has improved by 50% in the past decade, 2-fold age-related mortality differences persist. As in the 1980s, these differences are associated with lower rates of recognition of HIV, increased severity of illenss at admission, and delays in initiation of PCP-specific treatments among older individuals—factors suggestive of delayed recognition of HIV infection, pneumonia, and PCP, respectively. Continued vigilance for the possibility of HIV and HIV-related PCP among persons ≥50 years of age who present with new pulmonary symptoms should be encouraged.
