Objectives: The emergence of non-AIDS-related events in the HIV-infected population experiencing a longer life expectancy implies the implementation of a comprehensive approach of HIV clinical management through better access to care, prevention, and early diagnosis of co-morbidities.

Methods: The Orchestra program is a computer-assisted HIV care and support tool implemented since December 2004 in the outpatient clinic of a University Hospital set in Paris, France. The intervention aims at improving access to HIV information care and support specifically targeted five areas of actions: cardiovascular risk factors; gynecological follow-up; anti-hepatitis B virus (HBV) vaccine coverage; sexuality and prevention of sexually transmitted infections; and compliance to antiretrovirals. The impact of this program was examined prospectively on a "before-after" basis after a two-year implementation.

Results: In the two-year period, 1717 patients were regularly followed. The level of the database information significantly increased in time (low density lipoprotein (LDL) cholesterol and glycemia were informed in 74% of patients at inclusion versus 95% at two years, and 83% versus 97%, p < 0.001, respectively). The number of targeted interventions was also higher. For eligible women, papanicolaou smears and mammography were prescribed in 52% of cases after intervention, versus 44% at inclusion, p0.04 and 83% versus 50%, p < 0.001, respectively. Indicators of care eventually improved significantly. Initially 72% non-adherent patients declared to be adherent after the intervention ( p < 0.001) and 67% of patients with initial LDL-hypercholesterolemia normalized their LDL level within two years ( p < 0.001).

Conclusion: The Orchestra program has provided a unique opportunity to assess and improve prevention and management of co-morbidities in HIV patients.
