Effects of demand-side incentives in improving the utilisation of delivery services in Oyam District in northern Uganda: a quasi-experimental study.

BACKGROUND: We evaluated the effects and financial costs of two interventions with respect to utilisation of institutional deliveries and other maternal health services in Oyam District in Uganda. METHODS: We conducted a quasi-experimental study involving intervention and comparable/control sub-counties in Oyam District for 12 months (January-December 2014). Participants were women receiving antenatal care, delivery and postnatal care services. We evaluated two interventions: the provision of (1) transport vouchers to women receiving antenatal care and delivering at two health centres (level II) in Acaba sub-county, and (2) baby kits to women who delivered at Ngai Health Centre (level III) in Ngai sub-county. The study outcomes included service coverage of institutional deliveries, four antenatal care visits, postnatal care, and the percentage of women 'bypassing' maternal health services inside their resident sub-counties. We calculated the effect of each intervention on study outcomes using the difference in differences analysis. We calculated the cost per institutional delivery and the cost per unit increment in institutional deliveries for each intervention. RESULTS: Overall, transport vouchers had greater effects on all four outcomes, whereas baby kits mainly influenced institutional deliveries. The absolute increase in institutional deliveries attributable to vouchers was 42.9%; the equivalent for baby kits was 30.0%. Additionally, transport vouchers increased the coverage of four antenatal care visits and postnatal care service coverage by 60.0% and 49.2%, respectively. 'Bypassing' was mainly related to transport vouchers and ranged from 7.2% for postnatal care to 11.9% for deliveries. The financial cost of institutional delivery was US$9.4 per transport voucher provided, and US$10.5 per baby kit. The incremental cost per unit increment in institutional deliveries in the transport-voucher system was US$15.9; the equivalent for the baby kit was US$30.6. CONCLUSION: The transport voucher scheme effectively increased utilisation of maternal health services whereas the baby-kit scheme was only effective in increasing institutional deliveries. The transport vouchers were less costly than the baby kits in the promotion of institutional deliveries. Such incentives can be sustainable if the Ministry of Health integrates them in the health system.

Epstein-Barr virus load in children infected with human immunodeficiency virus type 1 in Uganda.

BACKGROUND: Epstein-Barr Virus (EBV) is involved in a wide range of malignancies, particularly in immunocompromised subjects. In Africa, EBV primary infection occurs during early childhood, but little is known about the EBV load in Human Immunodeficiency Virus type 1 (HIV-1)-infected children. METHODS: Blood samples from 213 HIV-1-infected children, 140 of whom were receiving antiretroviral therapy (ART), were collected at the Nsambya Hospital in Kampala, Uganda, and obtained for dried blood spot analysis. Nucleic acids were extracted and analyzed for quantification of EBV types 1 and 2; 16S ribosomal DNA (rDNA), a marker of microbial translocation; and HIV-1 RNA. RESULTS: Ninety-two of 140 children (66%) receiving ART and 57 of 73 ART-naive children (78%) had detectable EBV DNA levels. Coinfection with both EBV types was less frequent in ART-treated children than in ART-naive children (odds ratio, 0.54 [95% confidence interval {CI}, .30-.98]; P = .042). Mean EBV DNA levels (±standard deviation) were lower in the former (3.99 ± 0.59 vs 4.22 ± 0.54 log10 copies/mL; P = .006) and tended to be inversely associated with ART duration. EBV DNA levels were higher in children with an HIV-1 RNA load of > 3 log10 copies/mL of blood (regression coefficient, 0.32 [95% CI, .05-.59]; P = .020) and correlated with circulating 16S rDNA levels (rs = 0.25 [95% CI, .02-.46]; P = .031). CONCLUSIONS: These findings suggest that ART, by limiting HIV-1 replication, microbial translocation, and related immune activation, prevents superinfection with both EBV types and keeps EBV viremia down, thus potentially reducing the risk of EBV-associated lymphomas.

Viral load detection using dried blood spots in a cohort of HIV-1-infected children in Uganda: correlations with clinical and immunological criteria for treatment failure.

Correlations between clinical/immunological treatment failure and viral load (VL) detected by dried blood spot (DBS) sampling were explored in HIV-1-infected children in Uganda. Of 104 children on combined antiretroviral treatment (cART), 12.5% experienced clinical and/or immunological failure, while 28.8%, 44.2%, and 26.9% had VLs of <1,000, 1,000 to 5,000, and >5,000 copies/ml, respectively. Clinical/immunological failure poorly predicted virological failure.

Community health workers for ART in sub-Saharan Africa: learning from experience--capitalizing on new opportunities.

Low-income countries with high HIV/AIDS burdens in sub-Saharan Africa must deal with severe shortages of qualified human resources for health. This situation has triggered the renewed interest in community health workers, as they may play an important role in scaling-up antiretroviral treatment for HIV/AIDS by taking over a number of tasks from the professional health workers. Currently, a wide variety of community health workers are active in many antiretroviral treatment delivery sites. This article investigates whether present community health worker programmes for antiretroviral treatment are taking into account the lessons learnt from past experiences with community health worker programmes in primary health care and to what extent they are seizing the new antiretroviral treatment-specific opportunities. Based on a desk review of multi-purpose community health worker programmes for primary health care and of recent experiences with antiretroviral treatment-related community health workers, we developed an analytic framework of 10 criteria: eight conditions for successful large-scale antiretroviral treatment-related community health worker programmes and two antiretroviral treatment-specific opportunities. Our appraisal of six community health worker programmes, which we identified during field work in Ethiopia, Malawi and Uganda in 2007, shows that while some lessons from the past have been learnt, others are not being sufficiently considered and antiretroviral treatment-specific opportunities are not being sufficiently seized.In particular, all programmes have learnt the lesson that without adequate remuneration, community health workers cannot be retained in the long term. Yet we contend that the apparently insufficient attention to issues such as quality supervision and continuous training will lead to decreasing quality of the programmes over time. The life experience of people living with HIV/AIDS is still a relatively neglected asset, even though it may give antiretroviral treatment-related community health worker programmes better chances of success than their predecessors and may be crucially important for adherence and retention in large-scale antiretroviral treatment programmes. Community health workers as a community-based extension of health services are essential for antiretroviral treatment scale-up and comprehensive primary health care. The renewed attention to community health workers is thus very welcome, but the scale-up of community health worker programmes runs a high risk of neglecting the necessary quality criteria if it is not aligned with broader health systems strengthening. To achieve universal access to antiretroviral treatment, this is of paramount importance and should receive urgent attention.

Community perceptions on demand-side incentives to promote institutional delivery in Oyam district, Uganda: a qualitative study.

OBJECTIVE: To examine the perceptions of community members and other stakeholders on the use of baby kits and transport vouchers to improve the utilisation of childbirth services. DESIGN: A qualitative study. SETTING: Oyam district, Uganda. PARTICIPANTS: We conducted 10 focus group discussions with 59 women and 55 men, and 18 key informant interviews with local leaders, village health team members, health facility staff and district health management team members. We analysed the data using qualitative content analysis. RESULTS: Five broad themes emerged: (1) context, (2) community support for the interventions, (3) health-seeking behaviours postintervention, (4) undesirable effects of the interventions and (5) implementation issues and lessons learnt. Context regarded perceived long distances to health facilities and high transport costs. Regarding community support for the interventions, the schemes were perceived to be acceptable and helpful particularly to the most vulnerable. Transport vouchers were preferred over baby kits, although both interventions were perceived to be necessary. Health-seeking behaviours entailed perceived increased utilisation of maternal health services and 'bypassing', promotion of collaboration between traditional birth attendants and formal health workers, stimulation of men's involvement in maternal health, and increased community awareness of maternal health. Undesirable effects of the interventions included increased workload for health workers, sustainability concerns and perceived encouragement to reproduce and dependency. Implementation issues included information gaps leading to confusion, mistrust and discontent, transport voucher scheme design; implementation; and payment problems, poor attitude of some health workers and poor quality of care, insecurity, and a shortage of baby kits. Community involvement was key to solving the challenges. CONCLUSIONS: The study provides further insights into the implementation of incentive schemes to improve maternal health services utilisation. The findings are relevant for planning and implementing similar schemes in low-income countries.

Thermal Effect of a Woolen Cap in Low Birth Weight Infants During Kangaroo Care.

BACKGROUND AND OBJECTIVES: World Health Organization guidelines recommend covering the head during kangaroo mother care (KMC), but the effect of a cap on neonatal thermal control during KMC remains to be defined. Our objective was to assess the effectiveness and safety of a woolen cap in maintaining low birth weight infants (LBWIs) in normal thermal range during KMC. METHODS: Three hundred LBWI candidates for KMC in 3 African hospitals were randomly assigned to KMC with (CAP group) or without (NOCAP group) a woolen cap in a 1:1 ratio during the first week after birth. Axillary temperature was measured every 6 hours. Maternal and room temperature and adherence to skin-to-skin contact were registered at the same time points. RESULTS: A total number of 5064 measurements were recorded (median 19 measurements per subject; interquartile range: 10-25). Mean time spent in normal temperature range was 55% (SD 24) in CAP and 56% (SD 24) in NOCAP groups. Multivariable analysis estimated a rate ratio of 0.92 (95% confidence interval: 0.84 to 1.00; P = .06) for the effect of the cap versus no cap on time spent in the normal temperature range. CONCLUSIONS: In these 3 African, low-resource settings and so many days post birth, the use of a woolen cap was safe but provided no advantages in maintaining LBWI in the normal thermal range while being in a KMC ward. LBWIs spent only half of the time in the normal temperature range despite warm rooms and skin-to-skin contact. Maintaining normothermia in LBWIs remains an unfinished challenge in low-resource settings.

Is a woolen cap effective in maintaining normothermia in low-birth-weight infants during kangaroo mother care? Study protocol for a randomized controlled trial.

BACKGROUND: Neonatal hypothermia is an important challenge associated with morbidity and mortality. Preventing neonatal hypothermia is important in high-resource countries, but is of fundamental importance in low-resource settings where supportive care is limited. Kangaroo mother care (KMC) is a low-cost intervention that, whenever possible, is strongly recommended for temperature maintenance. During KMC, the World Health Organization (WHO) guidelines recommend the use of a cap/hat, but its effect on temperature control during KMC remains to be established. In the hospitals participating in the projects of the non-governmental organization CUAMM, KMC represents a standard of care, but the heads of the babies often remain uncovered due to local habits or to the unavailability of a cap. The aim of the present study will be to assess the effectiveness and safety of using a woolen cap in maintaining normothermia in low-birth-weight infants (LBWI) during KMC. METHODS/DESIGN: This is a multicenter (three hospitals), multicountry (three countries), prospective, unblinded, randomized controlled trial of KMC treatment with and without a woolen cap in LBWI. After obtaining parental consent, all infants with a birth weight below 2500 g and who are candidates for KMC, based on the clinical decision of the attending physician, will be assigned to the KMC with a woolen cap group or to the KMC without a woolen cap group in a 1:1 ratio according to a computer-generated, randomized sequence. The duration of the study will be until the patient's discharge, with a maximum treatment duration of 7 days. The primary outcome measure will be whether the infants' temperatures remain within the normal range (36.5-37.5 °C) in the course of KMC during the intervention. In all participants, axillary temperature will be measured with a digital thermometer four times per day. In addition, maternal and room temperature will be recorded. Secondary outcome measures will be: episodes of apnea; sepsis; mortality before hospital discharge; in-hospital growth; and age at discharge. DISCUSSION: The findings of this study will be important for other units/settings in high- as well low-resource countries where KMC is routinely performed. Based on the results of the present study, we could speculate whether the use of a woolen cap may help to maintain the neonate within the normal thermal range. Furthermore, potential complications such as hyperthermia will be strictly monitored and collected. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02645526 (registered on 31 December 2015).

Implementation and Operational Research: Implementation of the WHO 2011 Recommendations for Isoniazid Preventive Therapy (IPT) in Children Living With HIV/AIDS: A Ugandan Experience.

BACKGROUND: Intensified tuberculosis (TB) case finding and isoniazid preventive therapy (IPT) are strongly recommended for children who are HIV infected. Data are needed to assess the feasibility of the WHO 2011 intensified tuberculosis case finding/IPT clinical algorithm. METHODS: Children who are HIV infected and attending Nsambya Home Care at Nsambya Hospital, Uganda, were screened for TB following WHO recommendations. IPT was given for 6 months after excluding TB. Factors associated with time to IPT initiation were investigated by multivariate Cox proportional hazard regression. Health care workers were interviewed on reasons for delay in IPT initiation. RESULTS: Among the 899 (49% male) children with HIV, 529 (58.8%) were screened for TB from January 2011 to February 2013. Children with active TB were 36/529 (6.8%), 24 (4.5%) were lost to follow-ups and 280 (52.9%) started IPT, 86/280 (30.7%) within 3 months of TB screening and 194/280 (69.3%) thereafter. Among the 529 children screened for TB, longer time to IPT initiation was independently associated with cough at TB screening (hazard ratio 0.62, P = 0.02, 95% confidence interval: 0.41 to 0.94). Four children (1% of those starting treatments) interrupted IPT because of a 5-fold increase in liver function measurements. In the survey, Health care workers reported poor adherence to antiretroviral therapy, poor attendance to periodic HIV follow-ups, and pill burden as the 3 main reasons to delay IPT. CONCLUSION: In resource-constrained settings, considerable delays in IPT initiation may occur, particularly in children with HIV who are presenting with cough at TB screening. The good safety profile of isoniazid in antiretroviral-therapy-experienced children provides further support to IPT implementation in this population.

Predictors of Treatment Failure in HIV-Positive Children Receiving Combination Antiretroviral Therapy: Cohort Data From Mozambique and Uganda.

BACKGROUND: Delays detecting treatment failure and switching to second-line combination antiretroviral therapy (cART) are often observed in human immunodeficiency virus (HIV)-infected children of low-middle-income countries (LMIC). METHODS: An observational study included HIV-infected children attending the Beira Central Hospital (Mozambique) and the Nsambya Hospital, Home Care Department (Uganda) evaluated clinical and immunological failure according to World Health Organization (WHO) 2006 guidelines. Baseline predictors for cART failure and for drug substitution were explored in unadjusted and adjusted Cox proportional hazard models. RESULTS: Two hundred eighteen of 740 children with at least 24 weeks follow-up experienced treatment failure (29%; 95% confidence interval [CI] 26-33), with crude incidence of 20.0 events per 100 person-years (95% CI 17.5-22.9). Having tuberculosis co-infection or WHO stage 4, or starting a nontriple cART significantly increased risk of failure. Two hundred two of 769 (26.3%) children receiving cART substituted drug(s), with crude incidence of 15.4 events per 100 person-years (95% CI 13.4-17.7). Drug toxicity (18.3%), drug availability (17.3%), and tuberculosis drugs interaction (52, 25.7%) were main reported reasons, while only 9 (4%) patients switched cART for clinical or immunological failure. Children starting lamivudine-zidovudine-nevirapine or lamivudine-stavudine-efavirenz or lamivudine-zidovudine-efavirenz were more likely to have substitute drugs. Increased substitution was found in children with mild immunosuppression and tuberculosis co-infection at cART initiation as well as poor adherence before drug substitution. CONCLUSIONS: Considerable delay in switching to second-line cART may occur despite an observed high rate of failure. Factors including WHO clinical stage and tuberculosis co-infection should be evaluated before starting cART. Toxicity and drug adherence should be monitored to minimize drug substitution in LMIC.
