Utilization of prevention of mother-to-child transmission (PMTCT) services among pregnant women in HIV care in Uganda: a 24-month cohort of women from pre-conception to post-delivery

Cost-Effectiveness of Dolutegravir Compared With Efavirenz for Prevention of Perinatal Transmission in Women Presenting With HIV in Late Pregnancy in Uganda

OBJECTIVES

Dolutegravir (DTG) has proved to be more efficacious, tolerable, and safer than efavirenz (EFV) among mothers living with HIV and their infants in Uganda. This study assessed the cost-effectiveness of the DTG-based antiretroviral therapy (ART) compared with the standard of care for preventing perinatal transmissions among pregnant women initiating ART in late pregnancy in Uganda.

METHODS

We used data from a randomized open-label trial (DolPHIN-2) and a 2-part cost-effectiveness model composed of a short-term decision tree to estimate the perinatal transmission rate and costs and an individual-based 3-state Markov model (HIV, advanced HIV, dead) to estimate the long-term costs and health outcomes from the Ugandan payer perspective using a lifetime horizon and a 1-year Markov cycle. The main outcomes were the mean annual costs in US dollars ($), disability-adjusted life-years (DALYs), and incremental cost-effectiveness ratio. Both the deterministic and probabilistic sensitivity analyses were conducted to assess the effect of parameter uncertainties on the ultimate results and the model's robustness.

RESULTS

Compared with the EFV-based ART, the DTG-based ART was associated with fewer mean annual costs ($43.58 vs $68.44) and DALYs (0.33 vs 0.56), leading to cost savings of $110 per DALY averted. In the incremental analysis, the DTG-based ART dominated the EFV-based ART; that is, it was less costly and more effective. These results were robust to deterministic and probabilistic sensitivity analyses.

CONCLUSION

The DTG-based ART is a highly cost-effective strategy compared with the EFV-based ART among women initiating treatment in the third trimester of pregnancy in a low-income setting.

Understanding the uptake and determinants of prevention of mother-to-child transmission of HIV services in East Africa: Mixed methods systematic review and meta-analysis

BACKGROUND

Prevention of mother-to-child transmission (PMTCT) of HIV service is conceptualized as a series of cascades that begins with all pregnant women and ends with the detection of a final HIV status in HIV-exposed infants (HEIs). A low rate of cascade completion by mothers' results in an increased risk of HIV transmission to their infants. Therefore, this review aimed to understand the uptake and determinants of key PMTCT services cascades in East Africa.

METHODS

We searched CINAHL, EMBASE, MEDLINE, Scopus, and AIM databases using a predetermined search strategy to identify studies published from January 2012 through to March 2022 on the uptake and determinants of PMTCT of HIV services. The quality of the included studies was assessed using the Mixed Methods Appraisal Tool. A random-effects model was used to obtain pooled estimates of (i) maternal HIV testing (ii) maternal ART initiation, (iii) infant ARV prophylaxis and (iv) early infant diagnosis (EID). Factors from quantitative studies were reviewed using a coding template based on the domains of the Andersen model (i.e., environmental, predisposing, enabling and need factors) and qualitative studies were reviewed using a thematic synthesis approach.

RESULTS

The searches yielded 2231 articles and we systematically reduced to 52 included studies. Forty quantitative, eight qualitative, and four mixed methods papers were located containing evidence on the uptake and determinants of PMTCT services. The pooled proportions of maternal HIV test and ART uptake in East Africa were 82.6% (95% CI: 75.6-88.0%) and 88.3% (95% CI: 78.5-93.9%). Similarly, the pooled estimates of infant ARV prophylaxis and EID uptake were 84.9% (95% CI: 80.7-88.3%) and 68.7% (95% CI: 57.6-78.0) respectively. Key factors identified were the place of residence, stigma, the age of women, the educational status of both parents, marital status, socioeconomic status, Knowledge about HIV/PMTCT, access to healthcare facilities, attitudes/perceived benefits towards PMTCT services, prior use of maternal and child health (MCH) services, and healthcare-related factors like resource scarcity and insufficient follow-up supervision.

CONCLUSION

Most of the identified factors were modifiable and should be considered when formulating policies and planning interventions. Hence, promoting women's education and economic empowerment, strengthening staff supervision, improving access to and integration with MCH services, and actively involving the community to reduce stigma are suggested. Engaging community health workers and expert mothers can also help to share the workload of healthcare providers because of the human resource shortage.

Improving maternal and neonatal outcomes among pregnant women who are HIV-positive or HIV-negative through the Saving Mothers Giving Life initiative in Uganda: An analysis of population-based mortality surveillance data

HIV infection is associated with poor maternal health outcomes. In 2016, the maternal mortality ratio (MMR) in Uganda was 336/100,000, and the neonatal mortality rate (NMR) was 19/1,000. Saving Mothers, Giving Life (SMGL) was a five-year maternal and neonatal health strengthening initiative launched in 2012 in Uganda. We extracted maternal and neonatal data for 2015-2016 from the initiative's population-based mortality surveillance system in 123 health facilities in Western Uganda. We collected data on the facilities, HIV status, antiretroviral drug (ARV) use, death, birth weight, delivery type, parity, Apgar scores, and complications. We compared mother and baby outcomes between HIV-positive or HIV-negative, computed risk ratios (RR) for adverse outcomes, and used the chi-square to test for significance in differences observed. Among 116,066 pregnant women who attended and gave birth at SMGL-implementing facilities during 2015-2016, 8,307 (7.7%) were HIV-positive, of whom 7,809 (94%) used antiretroviral drugs (ARVs) at the time of delivery. During birth, 23,993 (21%) women experienced ≥1 complications. Neonate Apgar scores <7 (8.8%) and maternal haemorrhage during birth (1.6%) were the most common outcomes. Overall facility MMR was 258/100,000 and NMR was 7.6/1,000. HIV infection increased risk of maternal death (RR = 3.6, 95% Confidence Interval (CI) = 2.4-5.5), maternal sepsis (RR = 2.1, 95% CI = 1.3-3.3), and infant birth weight <2,500g (RR = 1.2, 95% CI = 1.1-1.3), but was protective against maternal complications (RR = 0.92, 95% CI = 0.87-0.97) and perinatal death (RR = 0.78, 95% CI = 0.68-0.89). Among the HIV-positive, ARV non-use increased risk of maternal death (RR = 15, 95% CI = 7.1-31) and perinatal death (RR = 2.3, 95% CI = 1.6-3.4). SMGL reduced facility MMR and NMR below national rates. HIV-infection was associated with maternal sepsis and death. Failure to use ARVs among women living with HIV increased the risk of maternal and perinatal death. Use of the SMGL approach and complementary interventions that further strengthen HIV care, may continue to reduce MMR and NMR.

A CROSS-SECTIONAL ASSESSMENT OF PHARMACISTS' KNOWLEDGE, ATTITUDE AND PRACTICE OF PREVENTION OF MOTHER-TO-CHILD TRANSMISSION OF HIV IN TWO NIGERIAN TEACHING HOSPITALS

Background

The pharmacological component of prevention of mother-to-child transmission (PMTCT) services involves the provision of antiretroviral agents (ARVs) to the mothers and/or their babies at any stage of pregnancy. This study assessed the knowledge, attitude and practice (KAP) of Pharmacists about PMTCT.

Materials and Methods

A questionnaire-based cross-sectional study was conducted among consenting Pharmacists at Ahmadu Bello University Teaching Hospital (ABUTH) and University of Nigeria Teaching Hospital (UNTH). Completed questionnaires were collated and analyzed using SPSS Version-25 with appropriate descriptive and inferential statistics. P-values less than 0.05 were considered to be statistically significant.

Results

A total of 77 Pharmacists participated in the study, with 54(70.13%) being from ABUTH. In ABUTH, 15(33.3%) Pharmacists identified as being females, against 16(69.6%) in UNTH. Majority (40,95.2%) of the Pharmacists in ABUTH had less than 10 years working experience as against 8(34.8%) in UNTH. Forty-eight (88.9%) respondents knew the correct meaning of PMTCT. The Pharmacists in ABUTH and UNTH had mean knowledge scores of 58.70±2.88% and 52.17±6.19%, respectively; t(75)=1.094, p=0.760. In ABUTH and UNTH, 16(69.6%) and 22(42.3%) Pharmacists, respectively, strongly agreed that PMTCT can prevent future infections in the infants. Their mean attitude scores were 69.65±1.22% (ABUTH) and 74.09±1.68% (UNTH); t(73)=-2.063, p=0.487. For practice, 4(5.33%) Pharmacists in both hospitals very often dispensed PMTCT drugs, while 37(70.83%) counseled PMTCT treatment-naïve patients.

Conclusion

The Pharmacists assessed in both hospitals had a fair knowledge of PMTCT services. Their attitudes to PMTCT was very good, although only a few of them had experience in providing care for PMTCT patients.

Factors associated with pregnancy uptake decisions among seropositive HIV people receiving antiretroviral therapy in sub‐Saharan Africa: A systematic review

Aim

This study determined the factors associated with pregnancy uptake decision among seropositive HIV people receiving antiretroviral therapy in sub‐Saharan Africa.

Design

Systematic review.

Methods

The population, intervention, comparison and outcomes framework was adopted to search for literature after a scoping review using the preferred reporting items for systematic reviews and meta‐analyses guidelines adopted in searching, and screening articles from four databases (PubMed, Cumulative Index to Nursing and Allied Health Literature, Embase, and Google scholar) to find 12 articles suitable for this study.

Results

Motivators of pregnancy uptake among HIV‐positive women include desire to have children, knowledge about PMTCT, cultural duty for married women to have children, and household income. Demotivating factors included the modern method of contraception and burden associated with pregnancy.

Conclusion

There is a need to improve on services that reduce conception‐related risks especially for women who choose to conceive and to incorporate fertility‐related counselling into HIV treatment services.

The Utilization of Voluntary Counseling and Testing Through Support and Family Health Care Functions

Background: The transmission of the Human Immunodeficiency Virus (HIV) from mother to baby is now increasing along with the growing number of HIV-infected women. Approximately 15% of pregnant women living with HIV have accessed antiretroviral (ARV) medicine to prevent transmission of the virus to their babies. Purpose: This study aimed to identify the support and healthcare functions available to pregnant women in using the voluntary counseling test (VCT). Methods: This research was conducted in the working area of Gianyar District health center. The independent variables in this study are family support and family healthcare functions. The dependent variable is the utilization of VCT health service facilities. This study employed a cross-sectional research design. The samples were 108 respondents recruited using a probability sampling technique, namely multi-stage sampling. Bivariate and multivariate analysis were conducted using the chi-square test and logistic regression test. Results: The research variable related to the use of VCT health services with family support showed an odds ratio (OR) = 122, while family healthcare function had an OR = 465. Conclusion: Pregnant women with good family support, good healthcare function, increased maternal age, and early gestational age were more likely to use VCT than when they were in opposite situations.

COVID-19 may exacerbate the clinical, structural and psychological barriers to retention in care among women living with HIV in rural and peri-urban settings in Uganda

BACKGROUND

Retention of pregnant and breastfeeding women and their infants in HIV care still remains low in Uganda. Recent literature has shown that the effects of COVID-19 mitigation measures may increase disease burden of common illnesses including HIV, Tuberculosis, Malaria and other key public health outcomes such as maternal mortality. A research program was undertaken to locate disengaged HIV positive women on option B+ and supported them to reengage in care. A 1 year follow up done following the tracing revealed that some women still disengaged from care. We aimed to establish the barriers to and facilitators for reengagement in care among previously traced women on option B+, and how these could have been impacted by the COVID-19 pandemic.

METHODS

This was a cross sectional qualitative study using individual interviews conducted in June and July, 2020, a period when the COVID-19 response measures such as lockdown and restrictions on transport were being observed in Uganda. Study participants were drawn from nine peri-urban and rural public healthcare facilities. Purposive sampling was used to select women still engaged in and those who disengaged from care approximately after 1 year since they were last contacted. Seventeen participants were included. Data was analysed using the content analysis approach.

RESULTS

Women reported various barriers that affected their reengagement and retention in care during the COVID-19 pandemic. These included structural barriers such as transport difficulties and financial constraints; clinical barriers which included unsupportive healthcare workers, short supply of drugs, clinic delays, lack of privacy and medicine side effects; and psychosocial barriers such as perceived or experienced stigma and non-disclosure of HIV sero-status. Supportive structures such as family, community-based medicine distribution models, and a friendly healthcare environment were key facilitators to retention in care among this group. The COVID-19 pandemic was reported to exacerbate the barriers to retention in care.

CONCLUSIONS

COVID-19 may exacerbate barriers to retention in HIV care among those who have experienced previous disengagement. We recommend community-based models such as drop out centres, peer facilitated distribution and community outreaches as alternative measures for access to ART during the COVID-19 pandemic.

Spatial pattern and determinants of sufficient knowledge of mother to child transmission of HIV and its prevention among Nigerian women

The lack of sufficient knowledge of mother to child transmission (MTCT) of human immunodeficiency virus (HIV) among pregnant women is considered a major contributor to new pediatric HIV infections globally, and increasing HIV related infant mortality especially in developing countries. Nigeria has the highest number of new HIV infections among children in the world. This study was designed to examine the spatial pattern and determinants of acquisition of sufficient knowledge of MTCT and prevention of mother to child transmission (PMTCT) in Nigeria. The data used in the study were extracted from the 2018 Nigeria Democratic Health Survey. The spatial modeling was through a Bayesian approach with appropriate prior distributions assigned to the different parameters of the model and inference was through the integrated nested Laplace approximation technique (INLA). Results show considerable spatial variability in the acquisition of sufficient knowledge of MTCT and its prevention with women in the southwestern and southeastern part of the country having higher likelihood. The nonlinear effects findings show that acquisition of sufficient knowledge of MTCT and PMTCT increased with age of women and peaked at around age 35yearswhere it thereafter dropped drastically among the older women. Furthermore, sufficient knowledge of MTCT and PMTCT was found to be driven by ethnicity, respondents' education and wealth status.

The yield of HIV testing during pregnancy and postnatal period, Uganda, 2015-2018: analysis of surveillance data

Background

Uganda has registered a reduction in new HIV infections among children in recent years. However, mother-to-child transmission of HIV still occurs, especially among pregnant women who present late. To eliminate this transmission, all HIV-positive pregnant women should be identified during antenatal HIV testing. We described women newly identified HIV-positive during pregnancy and postnatal period 2015–2018.

Methods

We extracted surveillance data for women identified as HIV-positive during pregnancy and the postnatal period reported through the Health Management Information System from 2015–2018. We calculated proportions newly positive at antenatal, labor, and postnatal periods nationally and at district levels. We disaggregated data into ‘tested early’ (during antenatal care) and ‘tested late’ (during labor or postnatal period) and calculated the proportion positive. We evaluated trends in these parameters at national and district levels.

Results

Overall, 8,485,854 mothers were tested for HIV during this period. Of these, 2.4% tested HIV-positive for the first time. While the total number of mothers tested increased from 1,327,022 in 2015 to 2,514,212 in 2018, the proportion testing HIV-positive decreased from 3.0% in 2015 to 1.7% in 2018 (43% decline over the study period, p < 0.001). Of 6,781,047 tested early, 2.2% tested HIV-positive. The proportion positive among those tested early dropped from 2.5% in 2015 to 1.7% in 2018. Of 1,704,807 tested late, 3.2% tested HIV-positive. The proportion positive among those tested late dropped from 5.2% in 2015 to 1.6% in 2018. At the district level, Kalangala District had the highest proportion testing positive at 13% (909/11,312) in 2015; this dropped to 5.2% (169/3278) in 2018.

Conclusion

The proportion of women newly testing HIV-positive during pregnancy and postnatal declined significantly during 2015–2018. A higher proportion of mothers who tested late vs early were HIV-positive. Failure to identify HIV early represents an increased risk of transmission. Ministry of Health should strengthen Elimination of Mother to Child Transmission (eMTCT) services to sustain this decrease through targeted interventions for poorly-performing districts. It should strengthen community-based health education on antenatal care and HIV testing and enhance the implementation of other primary prevention strategies targeting adolescents and young women.

"Our Choice" improves use of safer conception methods among HIV serodiscordant couples in Uganda: a cluster randomized controlled trial evaluating two implementation approaches

Background

Safer conception counseling (SCC) to promote the use of safer conception methods (SCM) is not yet part of routine family planning or HIV care. Guidelines for the use of SCM have been published, but to date there are no published controlled evaluations of SCC. Furthermore, it is unknown whether standard methods commonly used in resource constrained settings to integrate new services would be sufficient, or if enhanced training and supervision would result in a more efficacious approach to implementing SCC.

Methods

In a hybrid, cluster randomized controlled trial, six HIV clinics were randomly assigned to implement the SCC intervention Our Choice using either a high (SCC1) or low intensity (SCC2) approach (differentiated by amount of training and supervision), or existing family planning services (usual care). Three hundred eighty-nine HIV clients considering childbearing with an HIV-negative partner enrolled. The primary outcome was self-reported use of appropriate reproductive method (SCM if trying to conceive; modern contraceptives if not) over 12 months or until pregnancy.

Results

The combined intervention groups used appropriate reproductive methods more than usual care [20.8% vs. 6.9%; adjusted OR (95% CI)=10.63 (2.79, 40.49)], and SCC1 reported a higher rate than SCC2 [27.1% vs. 14.6%; OR (95% CI)=4.50 (1.44, 14.01)]. Among those trying to conceive, the intervention arms reported greater accurate use of SCM compared to usual care [24.1% vs. 0%; OR (95% CI)=91.84 (4.94, 1709.0)], and SCC1 performed better than SCC2 [34.6% vs. 11.5%; OR (95% CI)=6.43 (1.90, 21.73)]. The arms did not vary on modern contraception use among those not trying to conceive. A cost of $631 per person was estimated to obtain accurate use of SCM in SCC1, compared to $1014 in SCC2.

Conclusions

More intensive provider training and more frequent supervision leads to greater adoption of complex SCM behaviors and is more cost-effective than the standard low intensity implementation approach.

The At Risk Child Clinic (ARCC): 3 Years of Health Activities in Support of the Most Vulnerable Children in Beira, Mozambique

The concept of &ldquo;children at risk&rdquo; changes worldwide according to each specific context. Africa has a large burden of overall risk factors related to childhood health and development, most of which are of an infective or social origin. The aim of this study was to report and analyze the volumes of activities of fifteen At Risk Child Clinics (ARCCs) within the Beira District (Mozambique) over a 3 year-period in order to define the health profile of children accessing such health services. We retrospectively analyzed the data from all of the children accessing one of the 15 Beira ARCCs from January 2015 to December 2017. From this, 17,657 first consultations were registered. The motivations for accessing the services were in order of relevance: HIV exposure (n. 12,300; 69.7%), other risk conditions (n. 2542; 14.4%), Moderate Acute Malnutrition (MAM) (n. 1664; 9.4%), Severe Acute Malnutrition (SAM) (n. 772; 4.4%), and TB exposure (n. 542; 3.1%). During the first consultations, 16,865 children were screened for HIV (95.5%), and 7.89% tested HIV-positive. In our three years of experience, HIV exposure was the main indication for children to access the ARCCs in Mozambique. ARCCs could represent a strategic point to better understand health demands and to monitor the quality of care provided to this vulnerable population group, however significant effort is needed to improve the quality of the data collection.
