Introduction. Pregnant women are at a high risk of anaemia, with iron-folate deficiency being the most common cause of anaemia among pregnant women. Despite the well-known importance of iron and folic acid supplementation (IFAS) during pregnancy, adherence to these supplements is relatively low and associated factors were not well identified in the study area. This study is aimed at investigating adherence to IFAS and associated factors among pregnant women in Kasulu district, north-western Tanzania. Methods. A health facility cross-sectional survey with a mixed-method approach was conducted in Kasulu district from March to April 2019. A structured questionnaire was given to 320 women with children aged 0-6 months to assess factors associated with adherence to IFAS among pregnant women. Data were entered into SPSS version 22.0 for analysis. Binary logistic regression was further employed to determine the factors associated with adherence to IFAS. Focus group discussions were done with 19 pregnant women and 15 mothers of children aged 0-6 months to obtain more clarifications on the factors associated with adherence to IFAS. Furthermore, in-depth interviews were done with six health care providers to explore their perceptions of IFAS. Results. Out of the 320 respondents of the survey, 20.3% (n=65) adhered to IFAS. Factors associated with adherence to IFAS among pregnant women included time to start ANC (AOR=3.72, 95% CI: 1.42, 9.79), knowledge of anaemia (AOR=3.84, 95% CI: 1.335, 10.66), counseling on the importance of the iron-folic acid (AOR=3.86, 95% CI: 1.42, 10.50), IFAS given during clinical visit (AOR=15.72, 95% CI: 5.34, 46.31), number of meals consumed (AOR=3.44, 95% CI: 1.28, 9.21), number of children (AOR=3.462, 95% CI: 1.035, 11.58), and distance to health facility (AOR=0.34, 95% CI: 0.131, 0.886). Qualitative findings revealed that delayed first ANC visit, lack of remainder for pregnant women to take IFAS, low awareness about the negative effects of anaemia, low of knowledge of IFAS and management of side effects, negative beliefs about the use of IFAS, and follow-up mechanism were major reasons for poor adherence. Conclusion. Adherence to iron-folic acid supplementation during pregnancy was low. Strengthening systems for creating reminding mechanism, raising community awareness through educational programs to pregnant women and health providers could improve adherence to IFAS.

ObjectivesParasitological confirmation of malaria prior to treatment is recommended for patients of all ages, with malaria rapid diagnostic tests (mRDTs) an important tool to target artemisinin-based combination therapies (ACTs) to patients with malaria. To evaluate the impact on case management practices of routine government implementation of mRDTs, we conducted large-scale health facility surveys in three regions of Tanzania before and after mRDT roll-out.MethodsFebrile patients at randomly selected health facilities were interviewed about care received at the facility, and blood samples were collected for reference blood smears. Health facility staff were interviewed about their qualifications and availability of malaria diagnostics and drugs.ResultsThe percentage of febrile patients tested for malaria at the facility increased from 15.8% in 2010 to 54.9% in 2012. ACTs were obtained by 65.8% of patients positive by reference blood smear in 2010 and by 50.2% in 2012 (P = 0.0675); no antimalarial was obtained by 57.8% of malaria-negative patients in 2010 and by 82.3% in 2012 (P < 0.0001). Overall, ACT use decreased (39.9–21.3%, P < 0.0001) and antibiotic use increased (31.2–48.5%, P < 0.0001).ConclusionRoll-out of mRDTs in Tanzania dramatically improved diagnostic testing for malaria and reduced overuse of ACTs for patients without parasitemia. However, post–roll-out almost 50% of febrile patients did not receive a diagnostic test, and almost 50% of patients testing positive did not receive ACTs. Stock-outs of ACTs and mRDTs were important problems. Further investigation is needed to determine reasons for not providing ACTs to patients with malaria and potential for inappropriate antibiotic use.

Artemisinin combination therapies are available in private outlets, but patient adherence might be compromised by poor advice from dispensers. In this cluster randomized trial in drug shops in Tanzania, 42 of 82 selected shops were randomized to receive text message reminders about what advice to provide when dispensing artemether-lumefantrine (AL). Eligible patients purchasing AL at shops in both arms were followed up at home and questioned about each dose taken. Dispensers were interviewed regarding knowledge of AL dispensing practices and receipt of the malaria-related text messages. We interviewed 904 patients and 110 dispensers from 77 shops. Although there was some improvement in dispenser knowledge, there was no difference between arms in adherence measured as completion of all doses (intervention 68.3%, control 69.8%, p [adjusted] = 0.6), or as completion of each dose at the correct time (intervention 33.1%, control 32.6%, p [adjusted] = 0.9). Further studies on the potential of text messages to improve adherence are needed.

BackgroundSelf-report is the most common and feasible method for assessing patient adherence to medication, but can be prone to recall bias and social desirability bias. Most studies assessing adherence to artemisinin-based combination therapies (ACTs) have relied on self-report. In this study, we use a novel customised electronic monitoring device—termed smart blister packs—to examine the validity of self-reported adherence to artemether-lumefantrine (AL) in southern Tanzania.MethodsSmart blister packs were designed to look identical to locally available AL blister packs and to record the date and time each tablet was removed from packaging. Patients obtaining AL at randomly selected health facilities and drug stores were followed up at home three days later and interviewed about each dose of AL taken. Blister packs were requested for pill count and extraction of smart blister pack data.ResultsData on adherence from both self-report verified by pill count and smart blister packs were available for 696 of 1,204 patients. There was no difference between methods in the proportion of patients assessed to have completed treatment (64% and 67%, respectively). However, the percentage taking the correct number of pills for each dose at the correct times (timely completion) was higher by self-report than smart blister packs (37% vs. 24%; p<0.0001). By smart blister packs, 64% of patients completing treatment did not take the correct number of pills per dose or did not take each dose at the correct time interval.ConclusionSmart blister packs resulted in lower estimates of timely completion of AL and may be less prone to recall and social desirability bias. They may be useful when data on patterns of adherence are desirable to evaluate treatment outcomes. Improved methods of collecting self-reported data are needed to minimise bias and maximise comparability between studies.
