Guidelines for tuberculosis screening and preventive treatment among pregnant and breastfeeding women living with HIV in PEPFAR-supported countries.

BACKGROUND: Tuberculosis (TB) preventive treatment (TPT) is recommended by the World Health Organization (WHO) for persons living with HIV, including pregnant and breastfeeding women. Given the President's Emergency Plan for AIDS Relief (PEPFAR)'s investment in TPT services for persons living with HIV as a strategy to prevent TB as well as uncertainty in guidelines and policy regarding use of TPT during pregnancy and the postpartum period, we conducted a review of current relevant national guidelines among PEPFAR-supported countries. METHODS: Our review included 44/49 PEPFAR-supported countries to determine if TB screening and TPT are recommended specifically for pregnant and breastfeeding women living with HIV (WLHIV). National guidelines reviewed and abstracted included TB, HIV, prevention of vertical HIV transmission, TPT, and any other relevant guidelines. We abstracted information regarding TB screening, including screening tools and frequency; and TPT, including timing, regimen, frequency, and laboratory monitoring. RESULTS: Of 44 PEPFAR-supported countries for which guidelines were reviewed, 66% were high TB incidence countries; 41% were classified by WHO as high TB burden countries, and 43% as high HIV-associated TB burden countries. We found that 64% (n = 28) of countries included TB screening recommendations for pregnant WLHIV in their national guidelines, and most (n = 35, 80%) countries recommend TPT for pregnant WLHIV. Fewer countries included recommendations for breastfeeding as compared to pregnant WLHIV, with only 32% (n = 14) mentioning TB screening and 45% (n = 20) specifically recommending TPT for this population; most of these recommend isoniazid-based TPT regimens for pregnant and breastfeeding WLHIV. However, several countries also recommend isoniazid combined with rifampicin (3RH) or rifapentine (3HP). CONCLUSIONS: Despite progress in the number of PEPFAR-supported countries that specifically include TB screening and TPT recommendations for pregnant and breastfeeding WLHIV in their national guidelines, many PEPFAR-supported countries still do not include specific screening and TPT recommendations for pregnant and breastfeeding WLHIV.

The use of a monitoring tool to assess counselling and HIV testing in the public health sector in Malawi.

Scaling up of counselling and HIV testing (VCT) services requires a system of regular monitoring and evaluation. AVCT monitoring tool was developed through a consultative process and used to assess counselling and HIV testing services in 16 government and mission hospitals in Malawi, which had started expanded HIV-TB activities in July 2003. The essential components of theVCT monitoring tool included assessments of: (i) the hospital VCT personnel, in particular the number of counsellors (full-time and part-time) and those trained in and performing whole blood rapid HIV testing; (ii) the hospital laboratory service, in particular the protocols for HIV testing; (iii) the number, structure and function of dedicated VCT rooms; (iv) registers for patients, clients and donors having HIV tests; and (v) the quality of VCT through structured interviews with HIV-positive patients with TB. The main findings were: 9644 patients and clients were HIV tested between July and September 2003; HIV testing protocols were not standardized and differed between hospitals; there was little in the way of external quality assurance and there were deficiencies in the counselling process. In each hospital, the mean time taken to obtain the data and complete theVCT monitoring tool was 3 h. TheVCT monitoring tool is straightforward to use, and the data collected should help to improve standardization, quality and future planning of VCT services in the country.

Determinants of stillbirth in Zambia.

OBJECTIVE: The objective of this study was to estimate the rates and determinants of stillbirth in an urban African obstetric population. METHODS: In this retrospective cohort study, we reviewed vital outcomes of newborns whose mothers received antenatal care, delivery care, or both antenatal and delivery care in the Lusaka, Zambia, public sector between February 2006 and March 2009. We excluded newborns weighing less than 1,000 g, those whose mothers died before delivery, and those born outside Lusaka. RESULTS: There were 100,454 deliveries that met criteria for inclusion. The median maternal age at the initial visit was 24 years (interquartile range 21-29) and the median gestational age was 22 weeks (interquartile range 19-26). The median gestational age at birth was 38 weeks (interquartile range 36-40), and the median neonatal birth weight was 3,000 g (interquartile range 2,750-3,300). A total of 2,109 fetuses were stillborn (crude rate, 21 per 1,000 live births, 95% confidence interval 20.1 per 1,000 to 21.9 per 1,000). This included 1,049 (49.7%) stillbirths classified as "recent" (presumed to have occurred within 12 hours of delivery) and 1,060 (50.3%) classified as "macerated" (presumed to have occurred more than 12 hours before delivery). In adjusted analysis, increasing maternal age, baseline body mass index greater than 26, history of stillbirth, placental abruption, maternal untreated syphilis, cesarean delivery, operative vaginal delivery, assisted breech delivery, and extremes of neonatal birth weight were all significantly associated with stillbirth. CONCLUSION: Stillbirth is a major contributor to poor perinatal outcomes in Lusaka. Many deaths appear avoidable through investment in antenatal screening and better labor monitoring. Stillbirth should be adopted as a routine health indicator by the World Health Organization.

Implementation of the Zambia electronic perinatal record system for comprehensive prenatal and delivery care.

OBJECTIVE: To characterize prenatal and delivery care in an urban African setting. METHODS: The Zambia Electronic Perinatal Record System (ZEPRS) was implemented to record demographic characteristics, past medical and obstetric history, prenatal care, and delivery and newborn care for pregnant women across 25 facilities in the Lusaka public health sector. RESULTS: From June 1, 2007, to January 31, 2010, 115552 pregnant women had prenatal and delivery information recorded in ZEPRS. Median gestation age at first prenatal visit was 23weeks (interquartile range [IQR] 19-26). Syphilis screening was documented in 95663 (83%) pregnancies: 2449 (2.6%) women tested positive, of whom 1589 (64.9%) were treated appropriately. 111108 (96%) women agreed to HIV testing, of whom 22% were diagnosed with HIV. Overall, 112813 (98%) of recorded pregnancies resulted in a live birth, and 2739 (2%) in a stillbirth. The median gestational age was 38weeks (IQR 35-40) at delivery; the median birth weight of newborns was 3000g (IQR 2700-3300g). CONCLUSION: The results demonstrate the feasibility of using a comprehensive electronic medical record in an urban African setting, and highlight its important role in ongoing efforts to improve clinical care.

Antiretroviral therapy in antenatal care to increase treatment initiation in HIV-infected pregnant women: a stepped-wedge evaluation.

BACKGROUND: The objective of the study was to evaluate whether providing antiretroviral therapy (ART) integrated in antenatal care (ANC) clinics resulted in a greater proportion of treatment-eligible women initiating ART during pregnancy compared with the existing approach of referral to ART. ANALYSIS DESIGN AND METHODS: The evaluation used a stepped-wedge design and included all HIV-infected, ART-eligible pregnant women in eight public sector clinics in Lusaka district, Zambia. Main outcome indicators were the proportion of treatment-eligible pregnant women enrolling into HIV care within 60 days of HIV diagnosis, and of these, the proportion initiating ART during pregnancy. Adjusted odds ratios (AORs) and confidence intervals (CIs) for enrollment and initiation proportions were estimated through a logistic regression model accounting for clinical site cluster and time effects. RESULTS: Between 16 July 2007 and 31 July 2008, 13,917 women started antenatal care more than 60 days before the intervention rollout and constituted the control cohort; 17 619 started antenatal care after ART integrated into ANC and constituted the intervention cohort. Of the 1566 patients found eligible for ART, a greater proportion enrolled while pregnant and within the 60 days of HIV diagnosis in the intervention cohort (376/846, 44.4%) compared with the control cohort (181/716, 25.3%), AOR 2.06, 95% CI (1.27-3.34); and initiated ART while pregnant in the intervention cohort (278/846, 32.9%) compared with the control cohort (103/716, 14.4%), AOR 2.01, 95% CI (1.37-2.95). CONCLUSION: An integrated ART in ANC strategy doubled the proportion of treatment-eligible women initiating ART while pregnant.
