Supporting Option B+ scale up and strengthening the prevention of mother-to-child transmission cascade in central Malawi: results from a serial cross-sectional study.

BACKGROUND: We established Safeguard the Family (STF) to support Ministry of Health (MoH) scale-up of universal antiretroviral therapy (ART) for HIV-infected pregnant and breastfeeding women (Option B+) and to strengthen the prevention of mother-to-child transmission (PMTCT) cascade from HIV testing and counseling (HTC) through maternal ART provision and post-delivery early infant HIV diagnosis (EID). To these ends, we implemented the following interventions in 5 districts: 1) health worker training and mentorship; 2) couples' HTC and male partner involvement; 3) women's psychosocial support groups; and 4) health and laboratory system strengthening for EID. METHODS: We conducted a serial cross-sectional study using facility-level quarterly (Q) program data and individual-level infant HIV-1 DNA PCR data to evaluate STF performance on PMTCT indicators for project years (Y) 1 (April-December 2011) through 3 (January-December 2013), and compared these results to national averages. RESULTS: Facility-level uptake of HTC, ART, infant nevirapine prophylaxis, and infant DNA PCR testing increased significantly from quarterly baselines of 66 % (n/N = 32,433/48,804), 23 % (n/N = 442/1,958), 1 % (n/N = 10/1,958), and 52 % (n/N = 1,385/2,644) to 87 % (n/N = 39,458/45,324), 96 % (n/N = 2,046/2,121), 100 % (n/N = 2,121/2,121), and 62 % (n/N = 1,462/2,340), respectively, by project end (all p < 0.001). Quarterly HTC, ART, and infant nevirapine prophylaxis uptake outperformed national averages over years 2-3. While transitioning EID laboratory services to MoH, STF provided first-time HIV-1 DNA PCR testing for 2,226 of 11,261 HIV-exposed infants (20 %) tested in the MoH EID program in STF districts from program inception (Y2) through Y3. Of these, 78 (3.5 %) tested HIV-positive. Among infants with complete documentation (n = 608), median age at first testing decreased from 112 days (interquartile range, IQR: 57-198) in Y2 to 76 days (IQR: 46-152) in Y3 (p < 0.001). During Y3 (only year with national data for comparison), non-significantly fewer exposed infants tested HIV-positive (3.6 %) at first testing in STF districts than nationally (4.1 %) (p = 0.4). CONCLUSIONS: STF interventions, integrated within the MoH Option B+ program, achieved favorable HTC, maternal ART, infant prophylaxis, and EID services uptake, and a low proportion of infants found HIV-infected at first DNA PCR testing. Continued investments are needed to strengthen the PMTCT cascade, particularly around EID.

Assessment of peer-based and structural strategies for increasing male participation in an antenatal setting in Lilongwe, Malawi.

In sub-Saharan Africa, although male involvement in antenatal care is associated with positive outcomes for HIV-infected women and their infants, men rarely accompany female partners. We implemented a project to increase the number of male partners attending an antenatal clinic at Bwaila Hospital in Lilongwe, Malawi. We evaluated changes in the proportion of women who came with a partner over three periods. During period 1 (January 2007 - June 2008) there was didactic peer education. During period 2 (July 2008 - September 2009) a peer-led male-involvement drama was introduced into patient waiting areas. During period 3 (October 2009 - December 2009) changes to clinical infrastructure were introduced to make the clinic more male-friendly. The proportion of women attending ANC with a male partner increased from 0.7% to 5.7%, to 10.7% over the three periods. Peer education through drama and male-friendly hospital infrastructure coincided with substantially greater male participation, although further gains are necessary.

Evaluating the benefits of incorporating traditional birth attendants in HIV prevention of mother to child transmission service delivery in Lilongwe, Malawi.

The objective of our intervention was to examine the benefits of incorporating traditional birth attendants (TBA) in HIV Prevention of Mother to Child Transmission (PMTCT) service delivery. We developed a training curriculum for TBAs related to PMTCT and current TBA roles in Malawi. Fourteen TBAs and seven TBA assistants serving 4 urban health centre catchment areas were assessed, trained and supervised. Focus group discussions with the TBAs were conducted after implementation of the program. From March 2008 to August 2009, a total of 4017 pregnant women visited TBAs, out of which 2133 (53.1%) were directly referred to health facilities and 1,884 (46.9%) women delivered at TBAs and subsequently referred. 168 HIV positive women were identified by TBAs. Of these, 86/168 (51.2%) women received nevirapine and 46/168 (27.4%) HIV exposed infants received nevirapine. The challenges in providing PMTCT services included lack of transportation for referrals and absence of a reporting system to confirm the woman's arrival at the health center. Non-disclosure of HIV status by patients to the TBAs resulted in inability to assist nevirapine uptake. TBAs, when trained and well-supervised, can supplement efforts to provide PMTCT services in communities.

Ensuring HIV-infected pregnant women start antiretroviral treatment: an operational cohort study from Lilongwe, Malawi.

OBJECTIVES: HIV-infected women identified through antenatal care (ANC) often fail to access antiretroviral treatment (ART), leaving them and their infants at risk for declining health or HIV transmission. We describe results of measures to improve uptake of ART among eligible pregnant women. METHODS: Between October 2006 and December 2009, interventions implemented at ANC and ART facilities in urban Lilongwe aimed to better link services for women with CD4 counts <250/µl. A monitoring system followed women referred for ART to examine trends and improve practices in referral completion, on-time ART initiation and ART retention. RESULTS: Six hundred and twelve women were ART eligible: 604 (99%) received their CD4 result, 344 (56%) reached the clinic, 286 (47%) started ART while pregnant and 261 (43%) were either alive on ART or transferred out after 6 months. Between 2006 and 2009, the median (IQR) time between CD4 blood draw and ART initiation fell from 41 days (17, 349) to 15 days (7,42) (P = 0.183); the proportion of eligible individuals starting ART while pregnant and retained for 6 months improved from 17% to 65% (P < 0.001). Delays generally shortened within the continuum of care from 2006 to 2009; however, time from CD4 blood draw to ART referral increased from 7 to 14 days. CONCLUSIONS: Referrals between facilities and delays through CD4 count measurements create bottlenecks in patient care. Retention improved over time, but delays within the linkage process remained. ART initiation at ANC plus use of point-of-care CD4 tests may further enhance ART uptake.

Use of nutritional and water hygiene packages for diarrhoeal prevention among HIV-exposed infants in Lilongwe, Malawi: an evaluation of a pilot prevention of mother-to-child transmission post-natal care service.

SUMMARY OBJECTIVE: To evaluate a pilot prevention of mother-to-child transmission post-natal programme in Lilongwe, Malawi, through observed retention and infant diarrhoeal rates. METHODS: Free fortified porridge and water hygiene packages were offered to mothers to encourage frequent post-natal visits and to reduce diarrhoeal rates in infants on replacement feeding. Participant retention and infant health outcome were assessed. RESULTS: Of 474 patients enrolled, 357 (75.3%) completed 3-month follow-up visits. Ninety-nine percent of women reported hygiene package use, and only 17.7% (95% CI 13.8-22.0%) of the infants had diarrhoea at least once over the 3-month period. Being 12 months or younger, confirmed HIV positive, access to tap water, and having a mother with diarrhoea were all associated with increased risk of infant diarrhoea. CONCLUSION: The majority of participants adhered to their scheduled visits and retention was favourable, possibly because of the introduction of hygiene and nutrition incentives. The infant diarrhoeal rate was low, suggesting benefits of regular medical care with hygiene package usage and reliable replacement feeding options. Continuation and expansion of the programme would allow further studies and improve the post-natal care of HIV-exposed infants in Malawi and in other resource-constrained countries.

Exploring the feasibility of engaging Traditional Birth Attendants in a prevention of mother to child HIV transmission program in Lilongwe, Malawi.

OBJECTIVE: To investigate the willingness of Traditional Birth Attendants (TBAs) to provide single dose antiretroviral prophylaxis to infants born to mothers with HIV and the feasibility of providing the TBAs with antiretroviral medication. DESIGN: 2 focus groups with a total of 17 registered TBAs. SETTING: Lilongwe, Malawi. METHODS: TBAs were recruited by local health workers and participated in focus groups assessing their attitudes towards participation in a PMTCT program. RESULTS: TBAs were willing to participate in this prevention of mother-to-child HIV transmission (PMTCT) program and helped identify barriers to their participation. CONCLUSIONS: Given appropriate support and training, TBAs' participation in PMTCT programs could be an additional way to deliver medication to mothers and neonates who might otherwise miss crucial doses of medication.

Prevention of mother-to-child transmission: program changes and the effect on uptake of the HIVNET 012 regimen in Malawi.

OBJECTIVE(S): To evaluate uptake of HIV testing in a prevention of mother-to-child transmission program (PMTCT) in Lilongwe, Malawi from April 2002 until December 2006. DESIGN: Retrospective analysis of monthly reports from the beginning of the program. SETTING: Four antenatal clinics in Lilongwe, Malawi. METHODS: Pregnant women attending urban antenatal clinics in Lilongwe were invited to participate in a PMTCT program. Women were given information and education on antenatal care and PMTCT in groups of 8 to 12. Written informed consent for HIV testing was obtained privately. Women returned for the test result 1-2 weeks later. Mothers and infants were given the HIVNET 012 regimen. Rapid HIV testing and 'opt-out' testing were instituted in July 2003 and April 2005, respectively. Infants were tested using HIV DNA PCR and, if HIV positive, a CD4 cell percentage was obtained and the infants were referred for further medical evaluation and treatment. RESULTS: The program reached 20 000 pregnant women in the first 12 months. Acceptance of HIV testing increased from 45% to 73% (P < 0.001) when rapid, same day testing was instituted. When opt-out testing was instituted, 99% of the mothers agreed to testing. Of the infants tested, 15.5% were HIV positive. CONCLUSION: Rapid HIV testing using the opt-out method increased acceptance of HIV testing in the PMTCT program to 99% in urban Lilongwe, Malawi.
