HIVQUAL-T: monitoring and improving HIV clinical care in Thailand, 2002-08.

OBJECTIVE: We report experience of HIVQUAL-T implementation in Thailand. DESIGN: Program evaluation. SETTING: Twelve government hospital clinics. PARTICIPANTS: People living with HIV/AIDS (PLHAs) aged ≥15 years with two or more visits to the hospitals during 2002-08. INTERVENTION: HIVQUAL-T is a process for HIV care performance measurement (PM) and quality improvement (QI). The program includes PM using a sample of eligible cases and establishment of a locally led QI infrastructure and process. PM indicators are based on Thai national HIV care guidelines. QI projects address needs identified through PM; regional workshops facilitate peer learning. Annual benchmarking with repeat measurement is used to monitor progress. MAIN OUTCOME MEASURE: Percentages of eligible cases receiving various HIV services. RESULTS: Across 12 participating hospitals, HIV care caseloads were 4855 in 2002 and 13 887 in 2008. On average, 10-15% of cases were included in the PM sample. Percentages of eligible cases receiving CD4 testing in 2002 and 2008, respectively, were 24 and 99% (P< 0.001); for ARV treatment, 100 and 90% (P= 0.74); for Pneumocystis jiroveci pneumonia prophylaxis, 94 and 93% (P= 0.95); for Papanicolau smear, 0 and 67% (P< 0.001); for syphilis screening, 0 and 94% (P< 0.001); and for tuberculosis screening, 24 and 99% (P< 0.01). PM results contributed to local QI projects and national policy changes. CONCLUSIONS: Hospitals participating in HIVQUAL-T significantly increased their performance in several fundamental areas of HIV care linked to health outcomes for PLHA. This model of PM-QI has improved clinical care and implementation of HIV guidelines in hospital-based clinics in Thailand.

HIV/AIDS care and treatment in three provinces in northern Thailand before the national scale-up of highly-active antiretroviral therapy.

In 2003, Thailand launched a program to place 50,000 persons on highly active antiretroviral therapy (HAART) by the end of 2004, following a series of efforts since the early 1990s to develop comprehensive HIV/AIDS care services. To evaluate existing services and needs in advance of the national HAART scale-up, in 2002 we surveyed 31 hospitals and 389 community health centers in three northern Thai provinces, and interviewed 1,015 HIV-infected patients attending outpatient clinics. All hospitals offered voluntary HIV counseling and testing, 84% provided primary prophylaxis for Pneumocystis carinii pneumonia, 58% for tuberculosis, 39% for cryptococcal meningitis, and 87% had some experience providing antiretroviral therapy. Community health centers provided more limited service coverage. Of patients interviewed, 63% had been diagnosed with symptomatic HIV disease, and of these, 32% reported ever receiving antiretroviral therapy; 51 % of all patients had received a CD4 T-lymphocyte count. Thailand's current national HAART scale-up is being performed in a setting of well-developed hospital-based services introduced over the course of the epidemic.

Early HIV-1 diagnosis using in-house real-time PCR amplification on dried blood spots for infants in remote and resource-limited settings.

BACKGROUND: In resource-limited settings, most perinatally HIV-1-infected infants do not receive timely antiretroviral therapy because early HIV-1 diagnosis is not available or affordable. OBJECTIVE: To assess the performance of a low-cost in-house real-time polymerase chain reaction (PCR) assay to detect HIV-1 DNA in infant dried blood spots (DBS). METHODS: One thousand three hundred nineteen DBS collected throughout Thailand from non-breast-fed infants born to HIV-1-infected mothers were shipped at room temperature to a central laboratory.In-house real-time DNA PCR results were compared with Roche Amplicor HIV-1 DNA test (Version 1.5) results. In addition, we verified the Roche test performance on DBS sampled from 1218 other infants using as reference HIV serology result at 18 months of age. RESULTS: Real-time DNA PCR and Roche DNA PCR results were 100% concordant. Compared with HIV serology results, the Roche test sensitivity was 98.6% (95% confidence interval: 92.6% to 100.0%) and its specificity at 4 months of age was 99.7% (95% confidence interval: 99.2% to 99.9%). CONCLUSIONS: In-house real-time PCR performed as well as the Roche test in detecting HIV-1 DNA on DBS in Thailand. Combined use of DBS and real-time PCR assays is a reliable and affordable tool to expand access to early HIV-1 diagnosis in remote and resource-limited settings, enabling timely treatment for HIV-1-infected infants.
