Scaling up Pediatric HIV Testing by Incorporating Provider-Initiated HIV Testing Into all Child Health Services in Hurungwe District, Zimbabwe.

BACKGROUND: Practical ways are needed to scale-up pediatric HIV testing in sub-Saharan Africa, where testing is usually limited to HIV-exposed children in maternal and child health clinics. METHODS: We implemented an enhanced pediatric HIV testing program in 33 health facilities in Zimbabwe by integrating HIV testing into all pediatric health services. We collected individual data on children tested by having health care workers complete a program-specific child health booklet. We compared numbers of children tested before and during the program using routinely collected aggregate program data reported by health facilities. RESULTS: A total of 12,556 children aged 0-5 years were recorded in child health booklets; 9431 (75.1%) had information on HIV testing, of whom 7326 (77.7%) were tested; 7167 had test results of whom 122 (1.7%) were HIV-infected. Among children seen in outpatient clinics, 82.1% were tested compared with 66.5% tested among children seen in maternal/child health clinics. Of the 122 HIV-infected children identified, 77 (63.1%) could be missed under existing pediatric testing guidelines. The number of HIV-infected children identified during the 6-month program increased by 55% compared with the prior 6-month period (RR = 1.55, 95% CI: 1.22 to 1.96). Factors independently associated with HIV infection included being malnourished (adjusted odds ratio [AOR] = 7.7, 95% CI: 2.1 to 28.6), being exposed to TB (AOR = 8.1, 95% CI: 2.0 to 32.2), and having an HIV-infected mother (AOR = 41.6, 95% CI: 15.9 to 108.8). CONCLUSIONS: Integrating HIV testing into all pediatric health services is feasible and can assist in identifying HIV-infected children who could be missed in current testing guidelines.

Determinants of nondisclosure of HIV status among women attending the prevention of mother to child transmission programme, Makonde district, Zimbabwe, 2009.

INTRODUCTION: The 2007 United Nations General Assembly Report on HIV/AIDS in Zimbabwe reported nondisclosure of HIV status as a challenge in the PMTCT programme. Preliminary investigations on nondisclosure among 21 women tested for HIV at Chinhoyi Hospital showed that only six had disclosed their HIV status. We investigated the determinants of nondisclosure of HIV status. METHODS: A cross sectional analytic study was conducted at six health facilities in Makonde district. The Theory of Planned Behaviour was adapted to guide socio-cultural variables assessed. Antenatal and postnatal women tested for HIV in the PMTCT program who consented to participate were interviewed. RESULTS: We enrolled 334 women. Thirty four percent (114) did not disclose their HIV status. Among HIV positive respondents, 43% (25) did not disclose their status. Women who believed disclosure caused physical abuse (OR=1.81, 95% CI: 1.17-2.90), caused divorce (OR=2.01, 95% CI: 1.25-3.22) and was unimportant (OR= 2.26, 95% CI: 1.33-3.87) were two times less likely to disclose their status. Respondents who received group HIV pre-test counselling were 2.4 times more likely not to disclose. Receiving ANC HIV education at least twice and referral for psychosocial support were significantly protective [OR 0.54 (95% CI 0.24-0.63) and 0.16 (95% CI: 0.06-0.41) respectively. Independent determinants of nondisclosure among HIV positive women were perception that disclosure would cause divorce (AOR=7.82, p=0.03), living with an extended family (AOR=10.3, p=0.01) and needing spousal approval of HIV testing (AOR=0.11, p<0.001). CONCLUSION: Lack of psychosocial support and counselling for women and belief that disclosure causes divorce, abuse or is unimportant contributes to nondisclosure. Identifying women with social challenges and strengthening their referral for psychosocial support can improve disclosure of HIV status and reduce mother to child transmission of HIV.
