Measuring the effectiveness of an integrated intervention package to improve the level of infection prevention and control: a multi-centre study in Bangladesh.

BACKGROUND: Infection prevention and control (IPC) is a critical component of delivering safe, effective and high-quality healthcare services, and eliminating avoidable healthcare-associated infections (HAIs) in health facilities, predominantly in population-dense settings such as Bangladesh. AIM: Our study aimed to assess the effect of an integrated intervention package in improving the IPC level of the health facilities in Bangladesh. METHODS: We conducted a pre-post intervention study in six district hospitals (DHs) and 13 Upazila Health Complexes (UHCs) in the six districts of Bangladesh. Baseline and endline assessments were conducted between March and December 2021 using the adapted World Health Organization Infection Prevention and Control Assessment Framework (WHO-IPCAF) tool. The IPCAF score, ranging from 0-800, was calculated by adding the scores of eight components, and the IPC promotion and practice level was categorized as Inadequate (0-200), Basic (201-400), Intermediate (401-600) and Advanced (601-800). The integrated intervention package including IPC committee formation, healthcare provider training, logistics provision, necessary guidelines distribution, triage/flu corners establishment, and infrastructure development was implemented in all facilities. RESULTS: The average IPCAF score across all the facilities showed a significant increase from 16% (95% CI: 11.5-20.65%) to 54% (95% CI: 51.4-57.1%). Overall, the IPCAF score increased by 34 percentage points (P<0.001) in DHs and 40 percentage points (P<0.001) in UHCs. Following the intervention, 12 (three DHs, nine UHCs) of 19 facilities progressed from inadequate to intermediate, and another three DHs upgraded from basic to intermediate in terms of IPC level. CONCLUSION: The integrated intervention package improved IPCAF score in all facilities.

'What gets measured gets managed': revisiting the indicators for maternal and newborn health programmes.

BACKGROUND: The health of women and children are critical for global development. The Sustainable Development Goals (SDG) agenda and the Global Strategy for Women's, Children's, and Adolescent's Health 2016-2030 aim to reduce maternal and newborn deaths, disability, and enhancement of well-being. However, information and data on measuring countries' progress are limited given the variety of methodological challenges of measuring care around the time of birth, when most maternal and neonatal deaths and morbidities occur. MAIN BODY: In 2015, the World Health Organization launched Mother and Newborn Information for Tracking Outcomes and Results (MoNITOR), a technical advisory group to WHO. MoNITOR comprises 14 independent global experts from a variety of disciplines selected in a competitive process for their technical expertise and regional representation. MoNITOR will provide technical guidance to WHO to ensure harmonized guidance, messages, and tools so that countries can collect useful data to track progress toward achieving the Sustainable Development Goals. SHORT CONCLUSION: Ultimately, MoNITOR will provide technical guidance to WHO to ensure harmonized guidance, messages, and tools so that countries can collect useful data to track progress toward achieving the Sustainable Development Goals.

The development and evaluation of a community-based clinical diagnosis tool and treatment regimen for postpartum sepsis in Bangladesh and Pakistan.

BACKGROUND: Postpartum sepsis accounts for most maternal deaths between three and seven days postpartum, when most mothers, even those who deliver in facilities, are at home. Case fatality rates for untreated women are very high. Newborns of ill women have substantially higher infection risk. METHODS/DESIGN: The objectives of this study are to: (1) create, field-test and validate a tool for community health workers to improve diagnostic accuracy of suspected puerperal sepsis; (2) measure incidence and identify associated risk factors and; (3) describe etiologic agents responsible and antibacterial susceptibility patterns. This prospective cohort study builds on the Aetiology of Neonatal Infection in South Asia study in three sites: Sylhet, Bangladesh and Karachi and Matiari, Pakistan. Formative research determined local knowledge of symptoms and signs of postpartum sepsis, and a systematic literature review was conducted to design a diagnostic tool for community health workers to use during ten postpartum home visits. Suspected postpartum sepsis cases were referred to study physicians for independent assessment, which permitted validation of the tool. Clinical specimens, including urine, blood, and endometrial material, were collected for etiologic assessment and antibiotic sensitivity. All women with puerperal sepsis were given appropriate antibiotics. DISCUSSION: This is the first large population-based study to expand community-based surveillance for diagnoses, referral and treatment of newborn sepsis to include maternal postpartum sepsis. Study activities will lead to development and validation of a diagnostic tool for use by community health workers in resource-poor countries. Understanding the epidemiology and microbiology of postpartum sepsis will inform prevention and treatment strategies and improve understanding of linkages between maternal and neonatal infections.

Effect of community-based newborn care on cause-specific neonatal mortality in Sylhet district, Bangladesh: findings of a cluster-randomized controlled trial.

OBJECTIVES: Community-based maternal and newborn intervention packages have been shown to reduce neonatal mortality in resource-constrained settings. This analysis uses data from a large community-based cluster-randomized trial to assess the impact of a community-based package on cause-specific neonatal mortality and draws programmatic and policy implications. In addition, the study shows that cause-specific mortality estimates vary substantially based on the hierarchy used in assigning cause of death, which also has important implications for program planning. Therefore, understanding the methods of assigning causes of deaths is important, as is the development of new methodologies that account for multiple causes of death. The objective of this study was to estimate the effect of two service delivery strategies (home care and community care) for a community-based package of maternal and neonatal health interventions on cause-specific neonatal mortality rates in a rural district of Bangladesh. STUDY DESIGN: Within the general community of the Sylhet district in rural northeast Bangladesh. Pregnancy histories were collected from a sample of women in the study area during the year preceding the study (2002) and from all women who reported a pregnancy outcome during the intervention in years 2004 to 2005. All families that reported a neonatal death during these time periods were asked to complete a verbal autopsy interview. Expert algorithms with two different hierarchies were used to assign causes of neonatal death, varying in placement of the preterm/low birth weight category within the hierarchy (either third or last). The main outcome measure was cause-specific neonatal mortality. RESULT: Deaths because of serious infections in the home-care arm declined from 13.6 deaths per 1000 live births during the baseline period to 7.2 during the intervention period according to the first hierarchy (preterm placed third) and from 23.6 to 10.6 according to the second hierarchy (preterm placed last). CONCLUSION: This study confirms the high burden of neonatal deaths because of infection in low resource rural settings like Bangladesh, where most births occur at home in the absence of skilled birth attendance and care seeking for newborn illnesses is low. The study demonstrates that a package of community-based neonatal health interventions, focusing primarily on infection prevention and management, can substantially reduce infection-related neonatal mortality.

Household Animal and Human Medicine Use and Animal Husbandry Practices in Rural Bangladesh: Risk Factors for Emerging Zoonotic Disease and Antibiotic Resistance.

Animal antimicrobial use and husbandry practices increase risk of emerging zoonotic disease and antibiotic resistance. We surveyed 700 households to elicit information on human and animal medicine use and husbandry practices. Households that owned livestock (n = 265/459, 57.7%) reported using animal treatments 630 times during the previous 6 months; 57.6% obtained medicines, including antibiotics, from drug sellers. Government animal healthcare providers were rarely visited (9.7%), and respondents more often sought animal health care from pharmacies and village doctors (70.6% and 11.9%, respectively), citing the latter two as less costly and more successful based on past performance. Animal husbandry practices that could promote the transmission of microbes from animals to humans included the following: the proximity of chickens to humans (50.1% of households reported that the chickens slept in the bedroom); the shared use of natural bodies of water for human and animal bathing (78.3%); the use of livestock waste as fertilizer (60.9%); and gender roles that dictate that females are the primary caretakers of poultry and children (62.8%). In the absence of an effective animal healthcare system, villagers must depend on informal healthcare providers for treatment of their animals. Suboptimal use of antimicrobials coupled with unhygienic animal husbandry practices is an important risk factor for emerging zoonotic disease and resistant pathogens.

Preterm birth and neonatal mortality in a rural Bangladeshi cohort: implications for health programs.

OBJECTIVE: To estimate the burden of prematurity, determine gestational age (GA)-specific neonatal mortality rates and provide recommendations for country programs. STUDY DESIGN: Prospective data on pregnancy, childbirth, GA and newborn mortality collected by trained community health workers from 10 585 mother-newborn pairs in a community-based study. RESULT: A total of 19.4% of newborn infants were preterm; 13.5% were late preterm (born between 34 and 36 weeks of gestation), 3.3% were moderate preterm (born at 32 to 33 weeks) and 2.6% were extremely preterm (born at 28 to 31 weeks of gestation). Preterm babies experienced 46% of all neonatal deaths; 40% of preterm deaths were in late preterm, 20% in moderate preterm and 40% in very preterm infants. The population attributable fraction of neonatal mortality in premature babies was 0.16 for very preterm, 0.07 for moderately preterm and 0.10 for late preterm. CONCLUSION: In settings where the majority of births and newborn deaths occur at home and successful referral is a challenge, moderate and late preterm babies may be an important target group for home-based or first-level facility-based management.

Can mothers recognize neonatal illness correctly? Comparison of maternal report and assessment by community health workers in rural Bangladesh.

OBJECTIVES: To validate maternal recognition of neonatal illnesses at home compared to assessment by community health workers (CHWs) during routine household surveillance for neonatal illness in rural Bangladesh. METHODS: Surveillance in the intervention arm of two cluster-randomized, controlled trials of newborn interventions conducted in Sylhet and Mirzapur districts of Bangladesh. CHWs promoted birth and newborn care preparedness during two prenatal visits, including recognition of neonatal illnesses. CHWs assessed 8472 neonates on post-natal days 0, 3, and 6 between 2004 and 2005 in Sylhet, and 7587 neonates on post-natal days 0, 2, 5, and 8 between 2004 and 2006 in Mirzapur. In both sites, CHW identified neonates with very severe disease (VSD), using clinical algorithms that included ascertainment of illness history reported by mother and observation of clinical signs of illness. We calculated sensitivity, specificity, positive predictive value and negative predictive value of maternal report of any illness sign compared to CHWs' assessments and classification of VSD. Analysis was restricted to mothers whose neonates were assessed by CHWs at home during the routine visit schedule. RESULTS: Maternal report of any signs had sensitivity of 24% and 20% and positive predictive value of 45% and 54% in Sylhet and Mirzapur, respectively. CONCLUSIONS: Maternal recognition of neonatal illnesses at home was poor in two rural areas in Bangladesh. Interventions need to be designed to improve maternal recognition, and routine post-natal assessment by CHWs at home may be an essential component of community-based newborn care to improve care-seeking for newborn illness.

Supplementing iron and zinc: double blind, randomized evaluation of separate or combined delivery.

BACKGROUND/OBJECTIVES: Many children have diets deficient in both iron and zinc, but there has been some evidence of negative interactions when they are supplemented together. The optimal delivery approach would maximize clinical benefits of both nutrients. We studied the effectiveness of different iron and zinc supplement delivery approaches to improve diarrhea and anemia in a rural Bangladesh population. STUDY DESIGN: Randomized, double blind, placebo-controlled factorial community trial. RESULTS: Iron supplementation alone increased diarrhea, but adding zinc, separately or together, attenuated these harmful effects. Combined zinc and iron was as effective as iron alone for iron outcomes. All supplements were vomited <1% of the time, but combined iron and zinc were vomited significantly more than any of the other supplements. Children receiving zinc and iron (together or separately) had fewer hospitalizations. Separating delivery of iron and zinc may have some additional benefit in stunted children. CONCLUSIONS: Separate and combined administration of iron and zinc are equally effective for reducing diarrhea, hospitalizations and improving iron outcomes. There may be some benefit in separate administration in stunted children.

Factors influencing intestinal cadmium uptake in pregnant Bangladeshi women--a prospective cohort study.

Experimental studies indicate that zinc (Zn) and calcium (Ca) status, in addition to iron (Fe) status, affect gastrointestinal absorption of cadmium (Cd), an environmental pollutant that is toxic to kidneys, bone and endocrine systems. The aim of this study was to evaluate how various nutritional factors influence the uptake of Cd in women, particularly during pregnancy. The study was carried out in a rural area of Bangladesh, where malnutrition is prevalent and exposure to Cd via food appears elevated. The uptake of Cd was evaluated by associations between erythrocyte Cd concentrations (Ery-Cd), a marker of ongoing Cd exposure, and concentrations of nutritional markers. Blood samples, collected in early pregnancy and 6 months postpartum, were analyzed by inductively coupled plasma mass spectrometry (ICPMS). Ery-Cd varied considerably (range: 0.31-5.4microg/kg) with a median of 1.1microg/kg (approximately 0.5microg/L in whole blood) in early pregnancy. Ery-Cd was associated with erythrocyte manganese (Ery-Mn; positively), plasma ferritin (p-Ft; negatively), and erythrocyte Ca (Ery-Ca; negatively) in decreasing order, indicating common transporters for Cd, Fe and Mn. There was no evidence of Cd uptake via Zn transporters, but the association between Ery-Cd and p-Ft seemed to be dependent on adequate Zn status. On average, Ery-Cd increased significantly by 0.2microg/kg from early pregnancy to 6 months postpartum, apparently due to up-regulated divalent metal transporter 1 (DMT1). In conclusion, intestinal uptake of Cd appears to be influenced either directly or indirectly by several micronutrients, in particular Fe, Mn and Zn. The negative association with Ca may suggest that Cd inhibits the transport of Ca to blood.

Low-dose weekly supplementation of iron and/or zinc does not affect growth among Bangladeshi infants.

OBJECTIVES: To determine the effect of low-dose weekly supplementation with iron, zinc or both on growth of infants from 6 to 12 months of age. SUBJECTS/METHODS: A total of 645 breastfed infants age 6 months who were not severely anemic (Hb> or = 90 g l(-1)) or severely malnourished (weight-for-age > or = 60% median) were randomized to receive 20 mg iron and 1 mg riboflavin; 20 mg zinc and 1 mg riboflavin; 20 mg iron, 20 mg zinc and 1 mg riboflavin; or riboflavin alone (control) weekly for 6 months. RESULTS: Baseline characteristics were similar among the four supplementation groups. Weight, length and mid-upper arm circumference were assessed at baseline, 8, 10 and 12 months of age. There was no interaction of iron and zinc when given in a combined supplement on either weight or length (P>0.05). There were no effects of either iron or zinc on the rate of length or weight gain for all infants or when stratified by baseline Hb concentration. CONCLUSIONS: Weekly supplementation of 20 mg Fe, 20 mg Zn, or both does not benefit growth among infants 6-12 months of age in rural Bangladesh, a region with high rates of anemia and zinc deficiency.

Newborn umbilical cord and skin care in Sylhet District, Bangladesh: implications for the promotion of umbilical cord cleansing with topical chlorhexidine.

Newborn cord care practices may directly contribute to infections, which account for a large proportion of the four million annual global neonatal deaths. This formative research study assessed current umbilical and skin care knowledge and practices for neonates in Sylhet District, Bangladesh, in preparation for a cluster-randomized trial of the impact of topical chlorhexidine cord cleansing on neonatal mortality and omphalitis. Unstructured interviews (n=60), structured observations (n=20), rating and ranking exercises (n=40) and household surveys (n=400) were conducted to elicit specific behaviors regarding newborn cord and skin care practices. These included hand-washing, skin and cord care at the time of birth, persons engaged in cord care, cord cutting practices, topical applications to the cord at the time of birth, wrapping/dressing of the cord stump and use of skin-to-skin care. Overall 90% of deliveries occurred at home. The umbilical cord was almost always (98%) cut after delivery of the placenta, and cut by mothers in more than half the cases (57%). Substances were commonly (52%) applied to the stump after cord cutting; turmeric was the most common application (83%). Umbilical stump care revolved around bathing, skin massage with mustard oil and heat massage on the umbilical stump. Overall 40% of newborns were bathed on the day of birth. Mothers were the principal provider for skin and cord care during the neonatal period and 9% of them reported umbilical infections in their infants. Unhygienic cord care practices are prevalent in the study area. Efforts to promote hand-washing, cord cutting with clean instruments and avoiding unclean home applications to the cord may reduce exposure and improve neonatal outcomes. Such efforts should broadly target a range of caregivers, including mothers and other female household members.

[Conclusions and recommendations of a WHO expert consultation meeting on iron supplementation for infants and young children in malaria endemic areas]. / Conclusions et recommandations à l'issue de la consultation de l'OMS sur la lutte contre la carence martiale chez le nourrisson et le jeune enfant dans les pays d'endémie palustre.

This article presents the results of an expert consultation meeting aimed at evaluating the safety and public health implications of administering supplemental iron to infants and young children in malaria-endemic areas. Participants at this meeting that took place in Lyon, France on June 12-14, 2006 reached consensus on several important issues related to iron supplementation for infants and young children in malaria-endemic areas. The conclusions in this report apply specifically to regions where malaria is endemic.

Safety and immunogenicity of tetravalent rhesus-based rotavirus vaccine in Bangladesh.

BACKGROUND: Rotavirus is the most common cause of severe gastroenteritis among children worldwide. OBJECTIVES: To compare the safety, immunogenicity and shedding patterns of rhesus rotavirus (RRV)-tetravalent vaccine vs. placebo among infants in rural Bangladesh. METHODS: A double blinded, placebo-controlled trial was conducted in which infants (n = 120) were randomly assigned to receive three doses of either vaccine or placebo administered at approximately 6, 10 and 14 weeks of age together with routine immunizations. Data on possible adverse effects of vaccinations were collected daily for 7 days after each dose. Stool samples were collected after each dose, and serum samples were obtained before the first and after the third vaccination. RESULTS: Fever (> or = 38 degrees C), as measured by study assistants, was noted more frequently among vaccinees (15%) than among placebo recipients (2%) during the 7 days after vaccination but was not reported more frequently by parents of vaccinees vs. placebo recipients. Overall 87% of vaccinees had an antibody response (measured by IgA or anti-RRV-neutralizing antibodies) after vaccination compared with 32% of placebo recipients. Rates of seroconversion were higher among subjects with lower levels of prevaccination antibodies and those who shed rotavirus after vaccination. Vaccine strain viruses were detected in stools from placebo vaccine recipients who had evidence of IgA seroconversion. CONCLUSIONS: In this population RRV-tetravalent vaccine was comparably immunogenic and safe as in trials conducted in developed countries, where this vaccine has been proved effective in preventing severe rotavirus diarrhea. These data support continued evaluation of rotavirus vaccines in developing countries.

Coping with changing conditions: alternative strategies for the delivery of maternal and child health and family planning services in Dhaka, Bangladesh.

The door-to-door distribution of contraceptives and information on maternal and child health and family planning (MCH-FP) services, through bimonthly visits to eligible couples by trained fieldworkers, has been instrumental in increasing the contraceptive prevalence rate and immunization coverage in Bangladesh. The doorstep delivery strategy, however, is labour-intensive and costly. More cost-effective service delivery strategies are needed, not only for family planning services but also for a broader package of reproductive and other essential health services. Against this backdrop, operations research was conducted by the Centre for Health and Population Research at the International Centre for Diarrhoeal Disease Research, Bangladesh (ICDDR,B) from January 1996 to May 1997, in collaboration with government agencies and a leading national nongovernmental organization, with a view to developing and field-testing alternative approaches to the delivery of MCH-FP services in urban areas. Two alternative strategies featuring the withdrawal of home-based distribution and the delivery of basic health care from fixed-site facilities were tested in two areas of Dhaka. The clinic-based service delivery strategy was found to be a feasible alternative to the resource-intensive doorstep system in urban Dhaka. It did not adversely affect programme performance and it allowed the needs of clients to be addressed holistically through a package of essential health and family planning services.

Effects of environmental factors on child survival in Bangladesh: a case control study.

The need for further studies on relationships between deaths and environmental variables has been reported in the literature. This case-control study was, therefore, carried out to find out the associations between several social and environmental variables and deaths of children due to infectious diseases such as those leading to diarrhoea, acute respiratory infection, measles and other diseases. Six hundred and twenty-five deaths (cases) and an equal number of matched living children (controls) aged 1-59 months, were studied in rural Matlab. An analysis of crude and adjusted odds ratio showed differential associations. Sources of drinking water, amount of stored water, conditions of latrines, number of persons sleeping with the child and the type of cooking site were statistically significantly associated with deaths due to infectious diseases after controlling for breast feeding, immunization, and the family size. Significant associations were also observed between: (i) the sources of drinking water and deaths due to ARI, and (ii) conditions of latrines and deaths due to diarrhoeal diseases, after controlling for the confounding variables. Several other environmental factors also showed associations with these various death groups, but they were not statistically significant. The size of the samples in death groups (small) and the prevalence of more or less homogeneous environmental health conditions probably diminished the magnitude of the effects. The results of the study reconfirm the importance of environmental health intervention in child survival, irrespective of breast-feeding, immunization, and selected social variables.

PIP: Findings are reported from a case-control study conducted to assess the associations between several social and environmental variables and deaths of children due to infectious diseases, such as those leading to diarrhea, acute respiratory infection (ARI), measles, and other diseases. 625 deaths (cases) and an equal number of matched living children (controls) aged 1-59 months were studied in rural Matlab. Sources of drinking water, the amount of stored water, latrine conditions, the number of persons sleeping with the child, and the type of cooking site were statistically significantly associated with deaths due to infectious diseases after controlling for breast-feeding, immunization, and family size. Significant associations were also observed between sources of drinking water and deaths due to ARI, and conditions of latrines and deaths due to diarrheal diseases, after controlling for confounding variables. No other statistically significant environmental factors were associated with these various death groups. Study results confirm the importance of environmental health interventions in child survival, irrespective of breast-feeding, immunization, and selected social variables.

A comprehensive assessment of the quality of immunization services in one major area of Dhaka City, Bangladesh.

This report assesses the quality of service inputs, service processes and service outcomes (with the exception of coverage and effectiveness) for immunization services in Zone 3 of Dhaka City. The results indicate that in general, the providers of immunization services are knowledgeable, friendly and give technically appropriate immunizations. Client ratings of the quality of services are quite good. Access is 90% for childhood immunizations and 89% for tetanus toxoid (TT) immunizations for women with a child < 1 year old. Three areas were identified as needing attention: frequently missed opportunities for the promotion or provision of immunizations; uneven distribution and utilization of immunization sites, and some fundamental weaknesses of the TT immunization programme (lack of awareness among women of reproductive age about the importance of TT immunization, low access to it among women of reproductive age who do not have a child < 1 year of age, and confusion among women and service providers about the purpose of TT immunization and the dosage schedule). Efforts to monitor and strengthen the quality of EPI activities will facilitate further decline in the numbers of deaths and illnesses from vaccine-preventable diseases. The approaches used in this study and the typology for quality assessment are widely applicable elsewhere.

Centre for IMCI Research and Training: a centre of excellence.

PIP: This article describes the activities of the Matlab Integrated Management of Childhood Illness (IMCI) Evaluation Project in Bangladesh. IMCI strategy was adopted in 1992, to control diarrheal diseases and acute respiratory infections (ARIs), achieve universal childhood immunization, and provide other nutrition and disease-specific primary health care activities. The IMCI approach relies on interventions for integrating the prevention and treatment of major childhood illnesses by reducing mortality, reducing the frequency and severity of illnesses and disabilities, and improving child growth and development. There is integrated management of ARIs, diarrhea, measles, malaria, and malnutrition. The strategy involves family and community practices, case management skills of health workers, and health service delivery systems. Operations research documents improvements in health outcomes, efficiency of resource use, cost effectiveness, and adaptation to local conditions. Bangladesh is implementing two pilot IMCI projects in two thanas in a new initiative. Research will focus on family and community practices, clinical case management, operations research, and evaluation of the costs and efficacy of IMCI strategies in Matlab. Matlab's Training and Education Department will make major contributions to the adaptation of training materials and methodology of the research. The Centre of Excellence will train in facility management and illness management with practicums supported by the pilot projects. The Centre may become a regional resource center and coordinate all the training and national and global research of the program.^ieng
