Improving adherence to malaria treatment for children: the use of pre-packed chloroquine tablets vs. chloroquine syrup

Malaria is a major cause of morbidity and mortality among children under five in sub-Saharan Africa. Prompt diagnosis and adequate treatment of acute clinical episodes are essential to reduce morbidity and prevent complications and mortality. In many countries, chloroquine syrup is the mainstay of malaria treatment for children under five. Not only is syrup more expensive than tablets, adherence to the prescribed dose at home is a problem because mothers use wrongly sized measuring devices or have difficulty with the instructions. We investigated the impact of introducing pre-packed tablets for children on adherence to treatment and compared the total cost of the tablets with that of syrup. Children aged 0--5 years diagnosed with malaria at the clinic over a 6-week period received either pre-packed tablets or syrup by random assignment. The principal caregivers were interviewed at home on day 4 after attending the clinic. Of the 155 caregivers given pre-packed tablets, 91% (n=141) adhered to the recommended dosage, while only 42% (n=61) of 144 who were provided syrup did. Only 20% of caregivers who received syrup used an accurate 5 ml measure. The cost of treatment with tablets was about one-quarter that of syrup and 62% (n=96) of caregivers preferred tablets. Pre-packed chloroquine tablets are a viable alternative to syrup.     

Child malaria treatment practices among mothers in the district of Yanfolila, Sikasso region, Mali

We studied child malaria treatment practices among mothers living in the District of Yanfolila in southern Mali. For sampling, we first chose five of 13 health areas with probability proportional to size. Then villages, compounds and mothers with at least one child aged 1-5 years were randomly chosen. We assessed the spleen size of one 1-5 year-old child of each mother, collected a thick blood film and recorded the body temperature of every child whose mother thought he/she was sick. 399 mothers in 28 villages were interviewed with a structured questionnaire divided into two parts. If the child had had soumaya (a term previously associated with uncomplicated malaria) during the past rainy season, we asked about signs and symptoms, health-seeking behaviour (who the mother consulted first) and treatment. If not, information about knowledge of the disease and treatment to be given was collected. 86% of the mothers interviewed stated that their child had been sick and almost half of them had had soumaya. All mothers named at least one sign by which they recognized the disease. Vomiting, fever and dark urine/yellow eyes/jaundice were the three most common signs mentioned. 75.8% managed their child's disease at home and used both traditional and modern treatment. The most common anti-malarial drug was chloroquine, often given at inappropriate dosage. The sensitivity and specificity of the mothers' diagnosis was poor, although this might be explained by the large percentage of children who had already been treated at the time of the interview. The results of our survey call for prompt educational action for the correct treatment of uncomplicated malaria/soumaya, particularly for mothers and possibly for shopkeepers. The high spleen rate (58.1%) among randomly selected children confirms that malaria is a common disease in this area. Improved case-management at home could only be beneficial.     

Local terminology for medicines to treat fever in Bougouni District, Mali: implications for the introduction and evaluation of malaria treatment policies

OBJECTIVE: To explore Bambara language terminology and classification for locally available antimicrobial medicines in order to better target promotional messages and improve evaluation measures in Bougouni District, Mali. METHODS: Mothers (n = 20) and drug vendors (n = 15) were asked to freelist medicines used to treat childhood illnesses, and to identify all medicines that corresponded to each of the listed terms from an array of medicines displayed with their packaging. RESULTS: Each Bambara language medicine term can refer to numerous modern medicines, and each modern medicine has several Bambara names. The term nivakini (Nivaquine), often translated as 'chloroquine', refers to a wide range of medicines commonly used to treat malaria, many with no antimalarial effect. Antibiotics were also identified as common treatments for malaria. Mothers and vendors used slightly different terminology when discussing treatments for malaria, and sometimes employed the same term to refer to different medicines. Neither mothers nor vendors clearly differentiated between antimalarial medicines. Colour, shape and packaging play a large role in their recognition, classification and use. CONCLUSIONS: Current household survey methods are likely to provide inaccurate estimates of appropriate treatment of febrile illness, and thus alternative approaches are recommended. In introducing new malaria treatments, malaria control programmes should differentiate recommended treatments from other medications through distinctive packaging, drug appearance and appropriate Bambara language terms.     

People's perception of malaria in Mbarara,Uganda

To understand people's perceptions of malaria and their implications for control programmes, we held focus group discussions (FGDs) and conducted semi-structured interviews (SSIs) with community members in Mbarara, Uganda. Mosquitoes were perceived as the cause or transmitters of malaria but the causation/transmission model of people differed from biomedical facts. Convulsions, a common complication of malaria, were perceived as a supernatural ailment, best treated by traditional medicine, as was splenomegaly. More than 70% of the patients with malaria had treatment from non-public health sources. This included self-treatment (13%), use of traditional healers (12%) and use of private medical practitioners/pharmacists (69%). Although 26% (887/3309) used bednets to prevent malaria, only 7% of the nets were impregnated with insecticide. People who did not use bednets cited discomfort because of heat/humidity and their high cost as reasons. To improve malaria control in this area, people need to be educated on the connection between mosquitoes and malaria and on seeking biomedical treatment for convulsions. The malaria control programme could collaborate with traditional and private health care providers to increase promotion of insecticide-impregnated mosquito nets.     

Implementation of intermittent preventive treatment with sulphadoxine-pyrimethamine for control of malaria in pregnancy in Kisumu, western Kenya

OBJECTIVE: In 1998, the Kenyan Ministry of Health introduced intermittent preventive treatment (IPT) with sulphadoxine-pyrimethamine (SP), one treatment dose in the second trimester (16-27 weeks) and one treatment dose between 28 and 34 weeks of gestational age, for the control of malaria in pregnancy. We evaluated the coverage and determinants of receipt of IPT after its introduction in the Provincial Hospital in Kisumu, western Kenya. METHODS: Information on the use of IPT in pregnancy was collected from women who attended the antenatal clinic (ANC) and delivered in the same hospital. In exit interviews, we assessed patterns of IPT use in the ANC. RESULTS: Of 1498 women who delivered between June 1999 and June 2000, 23.7%, 43.4% and 32.9% received > or =2, 1 or no dose of SP, respectively. Late first ANC attendance was the most important factor contributing to incomplete IPT; 45% of the women started attending ANC in the third trimester. More women received at least one tetanus toxoid immunization than at least one dose of IPT (94%vs. 67%, P < 0.05). In exit interviews, 74% correctly associated IPT with treatment of malaria; however, knowledge on the need for the second dose was poor. Three per cent of the administrations were given despite contraindications. The agreement between gestational age by date of last menstrual period and by palpation was low (kappa = 0.1). CONCLUSIONS: Education of pregnant women and ANC staff to increase earlier attendance for ANC has the potential to substantially increase the proportion of women receiving two doses of IPT with SP.     

Use of antenatal care services and intermittent preventive treatment for malaria among pregnant women in Blantyre District, Malawi

Malaria in pregnancy contributes to low birth weight and increased infant mortality. As part of WHO's Roll Back Malaria initiative, African heads of state pledged that by 2005, 60% of pregnant women will receive malaria chemoprophylaxis or intermittent preventive treatment (IPT). We performed a cluster sample survey to study the use of sulfadoxine-pyrimethamine (SP) for IPT among recently pregnant women in February 2000 in Blantyre District, Malawi. Among 391 women in the sample, 98.6% had attended antenatal clinic at least once and 90.2% knew that SP/IPT was recommended during pregnancy. Overall, only 36.8% received the full recommended two-dose regimen of SP/IPT. Using data from 187 women with antenatal clinic cards, we found that residence location, housing type and gender/age/education of the head of household were not associated with failure to receive SP/IPT. Adjusting for education, multigravid women were more likely not to receive the recommended SP/IPT regimen (RR 1.2, 95% CI 1.02-1.5, P=0.03). A substantial effort to improve the delivery and use of SP/IPT in Malawi will be necessary, but the Roll Back Malaria 2005 goal appears achievable.     

Competitive facilitation of drug-resistant Plasmodium falciparum malaria parasites in pregnant women who receive preventive treatment

Intermittent preventive treatment in pregnancy (IPTp) is used to prevent Plasmodium falciparum malaria. However, parasites resistant to the IPTp drug sulfadoxine-pyrimethamine (SP) have emerged worldwide, and infections with mixed resistant and susceptible parasites are exacerbated by pyrimethamine in mice. In a prospective delivery cohort in Muheza, Tanzania, we examined the effects of SP IPTp on parasite resistance alleles, parasite diversity, level of parasitemia, and inflammation in the placenta. IPTp use was associated with an increased fraction of parasites carrying the resistance allele at DHPS codon 581, an increase in the level of parasitemia, and more intense placental inflammation. The lowest mean level of parasite diversity and highest mean level of parasitemia occurred in women after recent IPTp use. These findings support a model of parasite release and facilitation, whereby the most highly resistant parasites out-compete less fit parasite populations and overgrow under drug pressure. Use of partially effective anti-malarial agents for IPTp may exacerbate malaria infections in the setting of widespread drug resistance.     

The clinical impact of combining intermittent preventive treatment with home management of malaria in children aged below 5 years: cluster randomised trial

Objective To investigate the impact of seasonal intermittent preventive treatment (IPTc) on malaria‐related morbidity in children <5 years of age who already had access to home‐based management of malaria (HMM) for presumptive treatment of fevers. Method Thirty community‐based drug distributors (CDDs) from all 13 communities of a rural subdistrict in Ghana were trained to provide prompt treatment for presumptive malaria using artesunate‐amodiaquine (AS+AQ) to all children under 5 years of age. Six communities were randomised to also receive bimonthly courses of seasonal IPTc with AS+AQ in May, July and September of 2007. The primary outcome was the incidence rate of febrile episodes diagnosed presumptively as malaria by the CDDs in the communities in each intervention group. Cross‐sectional surveys were conducted to determine the prevalence of parasitaemia and anaemia among the study children. Results During the 6 months in which IPTc was delivered, incidence of fevers in communities given HMM+IPTc was lower than in communities given HMM alone, but this difference was not statistically significant (protective efficacy: 37.0%(95% CI: ?9.7 to 63.8; P = 0.14). However, incidence of presumptive malaria was significantly lower in IPTc communities when only children who received all three courses of IPTc were included in the analysis: protective efficacy 61.5% (95% CI:31.2–78.5; P = 0.018). Protection with IPTc was not followed by rebound morbidity in the following year. At the end of the intervention period, prevalence of asymptomatic parasitaemia was lower in communities that had received IPTc, but there were no differences in anaemia or haemoglobin concentration. Conclusion In this study area, incidence of fevers was lower in communities given three courses of IPTc during the time of peak transmission than in communities that received only HMM. However, high levels of coverage for IPTc will be necessary for maximum impact.     

Improving malaria home treatment by training drug retailers in rural Kenya

Recent global malaria control initiatives highlight the potential role of drug retailers to improve access to early effective malaria treatment. We report on the findings and discuss the implications of an educational programme for rural drug retailers and communities in Kenya between 1998 and 2001 in a study population of 70,000. Impact was evaluated through annual household surveys of over-the-counter (OTC) drug use and simulated retail client surveys in an early (1999) and a late (2000) implementation area. The programme achieved major improvements in drug selling practices. The proportion of OTC anti-malarial drug users receiving an adequate dose rose from 8% (n = 98) to 33% (n = 121) between 1998 and 1999 in the early implementation area. By 2001, and with the introduction of sulphadoxine pyrimethamine group drugs in accordance with national policy, this proportion rose to 64% (n = 441) across the early and late implementation areas. Overall, the proportion of shop-treated childhood fevers receiving an adequate dose of a recommended anti-malarial drug within 24 h rose from 1% (n = 681) to 28% (n = 919) by 2001. These findings strongly support the inclusion of private drug retailers in control strategies aiming to improve prompt effective treatment of malaria.     

Local fever illness classifications: implications for home management of malaria strategies

BACKGROUND: The Ugandan Ministry of Health has adopted the WHO Home Based Fever Management strategy (HBM) to improve access to antimalarial drugs for prompt (<24 h) presumptive treatment of all fevers in children under 5 years. Village volunteers will distribute pre-packed antimalarials free of charge to caretakers of febrile children 2 months to 5 years ('Homapaks'). OBJECTIVE: To explore the local understanding and treatment practices for childhood fever illnesses and discuss implications for the HBM strategy. METHODS: Focus Group Discussions were held with child caretakers in three rural communities in Kasese district, West Uganda, and analysed for content in respect to local illness classifications and associated treatments for childhood fevers. RESULTS: Local understanding of fever illnesses and associated treatments was complex. Some fever illness classifications were more commonly mentioned, including 'Fever of Mosquito', 'Chest Problem', 'the Disease', 'Stomach Wounds' and 'Jerks', all of which could be biomedical malaria. Although caretakers refer to all these classifications as 'fever' treatment differed; some were seen as requiring urgent professional western treatment and others were considered severe but 'non-western' and would preferentially be treated with traditional remedies. CONCLUSIONS: The HBM strategy does not address local community understanding of 'fever' and its influence on treatment. While HBM improves drug access, Homapaks are likely to be used for only those fevers where 'western' treatment is perceived appropriate, implying continued delayed and under-treatment of potential malaria. Hence, HBM strategies also need to address local perceptions of febrile illness and adapt information and training material accordingly.     

Severe malaria in children in areas with low, moderate and high transmission intensity in Uganda

OBJECTIVES: Age and transmission intensity are known to influence the manifestations of severe falciparum malaria in African children. However, it is unclear how specific clinical features such as seizures, impairment of consciousness, or respiratory distress vary with the parasite load and transmission intensity. We examined how the peripheral parasite load varies with transmission intensity and how this influences the symptoms and manifestations of severe malaria in children under 5 years in three areas with different malaria transmission intensity across Uganda. METHODS: We consecutively recruited 617 children with severe malaria presenting to three hospitals in areas with very low (51), moderate (367) and very high (199) transmission intensities and compared the age, admission parasite density and proportions of patients with different manifestations of severe disease. RESULTS: The median age (months) was inversely proportional to transmission intensity and declined with rising transmission (26.4 in very low, 18.0 in moderate and 9.0 under very high transmission). The highest proportion of patients reporting previous malaria admissions came from the area with moderate transmission. The geometric mean parasite density (18,357, 32,508 and 95,433/microl) and the proportion of patients with seizures (13.7%, 36.8% and 45.7%, P < 0.001) from very low, moderate and very high transmission respectively, increased with rising transmission. A linear increase with transmission was also observed in the proportion of those with repeated seizures (9.8%, 13.4% and 30.2%, P < 0.001) or impaired consciousness (7.8%, 12.8% and 18.1%, P = 0.029) but not respiratory distress. The proportion of patients with severe anaemia (19.6%, 24.8% and 37.7%, P = 0.002) mirrored that of patients with seizures. CONCLUSIONS: These findings suggest that heavy Plasmodium falciparum parasitaemia may be important in development of seizures, severe malarial anaemia and impaired consciousness in children under 5 years of age but may not be important in the development of respiratory distress.     

Artemether treatment of recrudescent Plasmodium falciparum malaria in children

Summary Intramuscular artemether given for five days was evaluated prospectively in 32 patients with acute recrudescent Plasmodium falciparum malaria. All patients had experienced one or more treatment failures with one or more courses of the following drugs: chloroquine, amodiaquine, sulphadoxine-pyrimethamine and erythromycin given alone or in combination. There was a prompt response to treatment with fever and parasite clearance times of 10.7 (3.6) h (range 6–24) and 32.3 (8.3) h (range 24–48) respectively. Parasite reduction at 24 h was 93.2 (7.8)% (range 75–100). The cure rate on day 14 was 100%. The drug was well tolerated. These results suggest that artemether is rapidly effective in acute recrudescent Plasmodium falciparum malaria and is without deleterious side effects.     

Home treatment of 'malaria' in children in rural Gambia is uncommon

Home treatment with antimalarials is a common practice in many countries, and may save lives by ensuring that more malaria cases receive prompt treatment. Through retrospective surveys we found that home treatment of young children with antimalarials was uncommon in rural Gambia. Few families kept medicines in the home in case of illness, 28% kept paracetamol and only 8% kept chloroquine. Less than 10% of cases of childhood 'malaria' had been treated with chloroquine at home, and 69% of those giving home medication did not know the correct dosage for a child. The most common course of treatment was the use of paracetamol and/or tepid sponging to reduce fever, before the child was taken to a government health facility. Treating a child with antimalarials at home was more costly than other forms of treatment. The low cost associated with the use of health services for children and the limited availability of antimalarials outside major towns contribute to the high use of government health services. This shows that that home treatment cannot be assumed to be the predominant mode of malaria treatment throughout Africa, and highlights the need for country-specific policies based on accurate local knowledge of treatment practices in both rural and urban areas.     

Prevalence of malaria parasitemia among clients seeking treatment for fever or malaria at drug stores in rural Tanzania 2004

OBJECTIVE: To determine the prevalence of malaria parasitemia and other common illnesses among drug store clients in one rural community, with a view to the potential role of specialist drug stores in expanding coverage of effective malaria treatment to households in highly endemic areas. METHOD: Follow-back study of 2466 client visits selected from all 10 drug stores operating in the town of Ikwiriri between May 30 and August 31 2004. Of these, 521 (21.2%) were made by or on behalf of persons ill with fever or malaria. Two hundred and ninety three were eligible as residents of the surrounding nine villages and all agreed to participate in the study. Each patient was evaluated by a clinical officer and provided a blood sample for malaria on the day of the shop visit, either at the shop or at home. RESULTS: Only 50 (17.1%) visits by or on behalf of febrile patients resulted in the purchase of an antimalarial drug, while an antipyretic medication was obtained at 226 visits (77.1%). Clinicians diagnosed malaria in 63.8% of patients. Malaria parasites were identified in blood film samples from 24.2% (95% CI: 19.6, 29.5). This is double the parasite prevalence rate of 10.7% (95% CI: 8.6, 13.1) obtained from a household survey of 1004 healthy individuals selected from these villages at the same time. It is not significantly lower than the prevalence observed among 880 clients presenting with fever at health facilities in the district: 29.7% (95% CI: 23.0, 37.3). The prevalence of malaria parasitemia among children younger than 5 years whose families sought fever treatment from drug stores (42.1%; 95% CI: 31.4, 53.5) was equal to that of children presenting with fever at health facilities (42.5%; 95% CI: 25.0, 62.2). CONCLUSIONS: Currently, drug store clients do not obtain malaria-specific treatment in the majority of cases where it might be warranted. Parasitological findings indicate that drug store clients, especially children, are as likely to be infected with malaria as patients seeking care for similar illnesses at health facilities. Drug stores may be attractive partners for policy makers eager to engage the private retail sector in expanding coverage of malaria treatment.     

Predictors of treatment error for children with uncomplicated malaria seen as outpatients in Blantyre district, Malawi

BACKGROUND: Past studies have shown that health workers in developing countries often do not follow clinical guidelines, though few studies have explored with appropriate methods why errors occur. To develop interventions that improve health worker performance, factors affecting treatment practices must be better understood. METHODS: We analysed data from a health facility survey in Blantyre District, Malawi, in which health workers were observed treating ill children, and then children were independently re-examined by 'gold-standard' study clinicians. The analysis was limited to children with uncomplicated malaria (defined according to Malawi's guidelines as fever or anaemia without signs of severe illness), and a treatment error was defined as failure to treat with an effective antimalarial. RESULTS: Twenty-eight health workers and 349 ill-child consultations were evaluated; 247 (70.8%) children were treated with an effective antimalarial, and 102 (29.2%) were subject to treatment error. Logistic regression analysis revealed that in-service malaria training was not associated with treatment quality (univariate odds ratio (OR) = 1.16, 95% confidence interval (CI): 0.46-2.93); whereas acute respiratory infections training was associated with making an error (adjusted OR (aOR) = 2.42, 95% CI: 1.23-4.76). High fever and chief complaint of fever were associated with fewer errors (aOR = 0.25, 95% CI: 0.10-0.60 and aOR = 0.25, 95% CI: 0.13-0.48, respectively). Errors were more likely to occur in consultations starting before 1 p.m. (aOR = 1.88, 95% CI: 1.07-3.31). Supervision was not associated with better treatment quality. CONCLUSIONS: These results suggest that the disease-specific training and supervision, performed before the survey, did not lead to long-term improvements in health care quality. Furthermore, case management training for one specific disease may have worsened quality of care for another disease. These results support integration of guidelines for multiple conditions. Interventions should be evaluated for unintended negative effects on overall quality of care.     

The efficacy of chloroquine, sulfadoxine-pyrimethamine and a combination of both for the treatment of uncomplicated Plasmodium falciparum malaria in an area of low transmission in western Uganda

We conducted an efficacy study of chloroquine (CQ), sulfadoxine-pyrimethamine (SP) and a combination of both (SP+CQ) for the treatment of uncomplicated malaria in an area of low transmission with low drug pressure. On day 3, fever clearance was 97.4% (95% CI, 86.8-99.9), 100% (95% CI, 87.2-100) and 96.6% (95% CI, 82.2-99.9) in the CQ, SP and SP+CQ groups, respectively, (P=0.65). On day 14, clinical success was 92.5% (95% CI, 79.6-98.4), 100% (95% CI, 87.2-100) and 100% (95% CI, 88.1-100) in the CQ, SP and CQ+SP groups, respectively. Clinical failure was seen in 7.5% with 5% (95% CI, 0.61-16.9) early treatment failure and 2.5% (95% CI, 0.06-13.2) late treatment failure of cases in the CQ group and 0% in the SP and SP+CQ groups. Parasitological resistance was observed at RI level in 10% (95% CI, 2.8-23.7), 18.5% (95% CI, 6.3-38.1) and 6.9% (95% CI, 0.85-22.8) for the CQ, SP and SP+CQ, respectively (P=0.37). There was no age-dependent difference in clinical failure or parasitological resistance in any of the treatment groups and prior CQ use within the last 2 weeks did not affect CQ treatment outcome. The findings of this study suggest that CQ is still effective for the treatment of uncomplicated malaria in this area of low transmission and SP. However, combination therapy of SP+CQ is recommended to delay the development SP resistance, and regular surveillance for emerging CQ and SP resistance is needed to plan for alternative antimalarial drug regimens.     

Intermittent preventive treatment using artemisinin-based combination therapy reduces malaria morbidity among school-aged children in Mali

Objective  To assess the efficacy of intermittent preventive treatment (IPT) against malaria in school-aged children.
Methods  This was an open randomized controlled trial of seasonal IPT among school children (IPTsc) aged 6–13 years in Kollé, Mali. The study began in September 2007 and completed follow-up in May 2008. Students were randomized to one of three study arms: Sulfadoxine–pyrimethamine plus artesunate (SP/AS), amodiaquine plus artesunate (AQ/AS) or vitamin C. All students received two full treatment doses, given 2 months apart during the season of high transmission from September to December. Groups were compared with respect to incidence of clinical malaria, asymptomatic parasitemia and haemoglobin concentration.
Results  A total of 296 students were randomized, and retention in the study was 99.3%. Clinical malaria incidence in the SP/AS and AQ/AS arms was reduced by 66.6% and 46.5%, respectively, vs . vitamin C ( P  < 0.001). There were fewer clinic visits for any cause among the children receiving SP/AS or AQ/AS ( P  = 0.024). The prevalence of asymptomatic parasitemia was fivefold higher in the vitamin C arm than either SP/AS or AQ/AS at each post-treatment evaluation ( P  < 0.001). At the end of the transmission period, children treated with IPT had lower rates of anaemia (SP/AS, 17.7%; AQ/AS, 16.0%; vitamin C, 29.6%; P  = 0.039).
Conclusion  IPT among school children reduced the rates of clinical malaria, all-cause acute clinic visits, asymptomatic parasitemia and anaemia among school-aged children.     

Intermittent preventive treatment of malaria in pregnancy: the effect of new delivery approaches on access and compliance rates in Uganda

OBJECTIVE: To assess whether traditional birth attendants, drug-shop vendors, community reproductive health workers and adolescent peer mobilizers can administer intermittent preventive treatment (IPT) with sulfadoxine-pyremethamine to pregnant women, and reach those most at risk of malaria and increase access and compliance to it. METHODS: The study was designed to assess new approaches of delivering IPT through these groups and compare it with IPT at health units. The primary outcome measures were: the proportion of adolescents and primigravidae accessed; gestational age at recruitment and the proportion of women who completed two doses of sulfadoxine-pyremethamine. RESULTS: Two thousand seven hundred and eighty-five pregnant women (78% of those in the study area) participated. With new approaches, 92.4% of the women received IPT during the second trimester as recommended by the policy, vs. 76.1% at health units, P < 0.0001. Of the women who received two doses of sulfadoxine-pyremethamine, 39.9% were at health units (control) vs. 67.5% through new approaches (P < 0.0001). Women using the new approaches also accessed IPT early: the mean gestational age when receiving the first dose of sulfadoxine-pyremethamine was 21.0 weeks vs. 23.1 weeks at health units (P < 0.0001). However, the health units were used by a higher proportion of primigravidae (23.6% vs. 20.0%, P < 0.04), and this was also the case for adolescents (28.4% vs. 25.0%, P < 0.03). This intervention was acceptable with 89.1% of the women at the new approaches intending to use IPT in future. CONCLUSIONS: The new approaches increased access to and compliance with IPT. We recommend a review of the policy to allow the provision of IPT through the new approaches.
