RESUMO
INTRODUCTION: Existing risk assessment tools to identify children at risk of hospitalised pneumonia-related mortality have shown suboptimal discriminatory value during external validation. Our objective was to derive and validate a novel risk assessment tool to identify children aged 2-59 months at risk of hospitalised pneumonia-related mortality across various settings. METHODS: We used primary, baseline, patient-level data from 11 studies, including children evaluated for pneumonia in 20 low-income and middle-income countries. Patients with complete data were included in a logistic regression model to assess the association of candidate variables with the outcome hospitalised pneumonia-related mortality. Adjusted log coefficients were calculated for each candidate variable and assigned weighted points to derive the Pneumonia Research Partnership to Assess WHO Recommendations (PREPARE) risk assessment tool. We used bootstrapped selection with 200 repetitions to internally validate the PREPARE risk assessment tool. RESULTS: A total of 27 388 children were included in the analysis (mean age 14.0 months, pneumonia-related case fatality ratio 3.1%). The PREPARE risk assessment tool included patient age, sex, weight-for-age z-score, body temperature, respiratory rate, unconsciousness or decreased level of consciousness, convulsions, cyanosis and hypoxaemia at baseline. The PREPARE risk assessment tool had good discriminatory value when internally validated (area under the curve 0.83, 95% CI 0.81 to 0.84). CONCLUSIONS: The PREPARE risk assessment tool had good discriminatory ability for identifying children at risk of hospitalised pneumonia-related mortality in a large, geographically diverse dataset. After external validation, this tool may be implemented in various settings to identify children at risk of hospitalised pneumonia-related mortality.

BACKGROUND: India has made substantial progress in improving child health in recent years. However, the country continues to account for a large number of vaccine preventable child deaths. We estimated wealth-related full immunization inequalities in India. We also calculated the degree to which predisposing, reinforcing, and enabling factors contribute to these inequalities. METHODS: We used data from the two rounds of a large nationally representative survey done in all states in India in 2005-06 (n = 9582) and 2015-16 (n = 49,284). Full immunization status was defined as three doses of diphtheria-tetanus-pertussis vaccine, three doses of polio vaccine, one dose of Bacillus Calmette-Guérin vaccine, and one dose of measles vaccine in children 12-23 months. We compared full immunization coverage by wealth quintiles using descriptive statistics. We calculated concentration indices for full immunization coverage at the national and state levels. Using predisposing, reinforcing, and enabling factors associated with full immunization status identified from the literature, we applied a generalized linear model (GLM) framework with a binomial distribution and an identity link to decompose the concentration index. RESULTS: National full immunization coverage increased from 43.65% in 2005-06 to 62.46% in 2015-16. Overall, full immunization coverage in both 2005-06 and 2015-16 in all states was lowest in children from poorer households and improved with increasing socioeconomic status. The national concentration index decreased from 0.36 to 0.13 between the two study periods, indicating a reduction in poor-rich inequality. Similar reductions were observed for most states, except in states where inequalities were already minimal (i.e., Tamil Nadu) and in some northeastern states (i.e., Meghalaya and Manipur). In 2005-06, the contributors to wealth-related full immunization inequality were antenatal care, maternal education, and socioeconomic status. The same factors contributed to full immunization inequality in 2015-16 in addition to difficulty reaching a health facility. CONCLUSIONS: Immunization coverage and wealth-related equality have improved nationally and in most states over the last decade in India. Targeted, context-specific interventions could help address overall wealth-related full immunization inequalities. Intensified government efforts could help in this regard, particularly in high-focus states where child mortality remains high.

OBJECTIVES: While India has made substantial progress in introducing new vaccines and scaling up immunization coverage, inequities persist sub-nationally. This study was performed to investigate the risk of under-immunization based on class membership and to identify heterogeneous classes based on sociodemographic characteristics in pediatric and maternal populations in India through latent class analysis. METHODS: Data from the most recent National Family Health Survey conducted in 2015-2016 were used. Latent class analysis was used to model immunization coverage in children aged 12-23 months and mothers, and to identify subgroups to characterize those at risk of not being immunized. RESULTS: Patterns of sociodemographic characteristics were found to contribute to non-immunization or under-immunization among pediatric and maternal populations in India. Individuals who fit into one of three categories were identified in both populations: those at high, medium, and lower risk of not being immunized. Lower socioeconomic status, lack of antenatal care, and lower maternal education put individuals at higher risk of not being immunized with routine childhood vaccines and maternal tetanus toxoid. CONCLUSIONS: Predisposing risk factors can persistently impact immunization status despite improvements in immunization access in India. Tailored programmatic interventions should be developed to improve immunization coverage among those children and mothers who are at highest risk of being under-immunized or not immunized.

BACKGROUND: India accounts for a disproportionate burden of global childhood illnesses. To inform policies and measure progress towards achieving child health targets, we estimated the annual national and state-specific childhood mortality and morbidity attributable to Streptococcus pneumoniae and Haemophilus influenzae type b (Hib) between 2000 and 2015. METHODS: In this modelling study, we used vaccine clinical trial data to estimate the proportion of pneumonia deaths attributable to pneumococcus and Hib. The proportion of meningitis deaths attributable to each pathogen was derived from pathogen-specific meningitis case fatality and bacterial meningitis case data from surveillance studies. We applied these proportions to modelled state-specific pneumonia and meningitis deaths from 2000 to 2015 prepared by the WHO Maternal and Child Epidemiology Estimation collaboration (WHO/MCEE) on the basis of verbal autopsy studies from India. The burden of clinical and severe pneumonia cases attributable to pneumococcus and Hib was ascertained with vaccine clinical trial data and state-specific all-cause pneumonia case estimates prepared by WHO/MCEE by use of risk factor prevalence data from India. Pathogen-specific meningitis cases were derived from state-level modelled pathogen-specific meningitis deaths and state-level meningitis case fatality estimates. Pneumococcal and Hib morbidity due to non-pneumonia, non-meningitis (NPNM) invasive syndromes were derived by applying the ratio of pathogen-specific NPNM cases to pathogen-specific meningitis cases to the state-level pathogen-specific meningitis cases. Mortality due to pathogen-specific NPNM was calculated with the ratio of pneumococcal and Hib meningitis case fatality to pneumococcal and Hib meningitis NPNM case fatality. Census data from India provided the population at risk. FINDINGS: Between 2000 and 2015, estimates of pneumococcal deaths in Indian children aged 1-59 months fell from 166â000 (uncertainty range [UR] 110â000-198â000) to 68â700 (44â600-86â000), while Hib deaths fell from 82â600 (52â300-112â000) to 15â600 (9800-21â500), representing a 58% (UR 22-78) decline in pneumococcal deaths and an 81% (59-91) decline in Hib deaths. In 2015, national mortality rates in children aged 1-59 months were 56 (UR 37-71) per 100â000 for pneumococcal infection and 13 (UR 8-18) per 100â000 for Hib. Uttar Pradesh (18â900 [UR 12â300-23â600]) and Bihar (8600 [5600-10â700]) had the highest numbers of pneumococcal deaths in 2015. Uttar Pradesh (9300 [UR 5900-12â700]) and Odisha (1100 [700-1500]) had the highest numbers of Hib deaths in 2015. Less conservative assumptions related to the proportion of pneumonia deaths attributable to pneumococcus indicate that as many as 118â000 (UR 69â000-140â000) total pneumococcal deaths could have occurred in 2015 in India. INTERPRETATION: Pneumococcal and Hib mortality have declined in children aged 1-59 months in India since 2000, even before nationwide implementation of conjugate vaccines. Introduction of the Hib vaccine in several states corresponded with a more rapid reduction in morbidity and mortality associated with Hib infection. Rapid scale-up and widespread use of the pneumococcal conjugate vaccine and sustained use of the Hib vaccine could help accelerate achievement of child survival targets in India.

The study examines the impact of the introduction of 10-valent Pneumococcal Conjugate Vaccine (PCV10) into Bangladesh's national vaccine program. PCV10 is administered to children under 1 year-old; the scheduled ages of administration are at 6, 10, and 18 weeks. The study is conducted in ~770,000 population containing ~90,000 <5 children in Sylhet, Bangladesh and has five objectives: 1) To collect data on community-based pre-PCV incidence rates of invasive pneumococcal diseases (IPD) in 0-59 month-old children in Sylhet, Bangladesh; 2) To evaluate the effectiveness of PCV10 introduction on Vaccine Type (VT) IPD in 3-59 month-old children using an incident case-control study design. Secondary aims include measuring the effects of PCV10 introduction on all IPD in 3-59 month-old children using case-control study design, and quantifying the emergence of Non Vaccine Type IPD; 3) To evaluate the effectiveness of PCV10 introduction on chest radiograph-confirmed pneumonia in children 3-35 months old using incident case-control study design. We will estimate the incidence trend of clinical and radiologically-confirmed pneumonia in 3-35 month-old children in the study area before and after introduction of PCV10; 4) To determine the feasibility and utility of lung ultrasound for the diagnosis of pediatric pneumonia in a large sample of children in a resource-limited setting. We will also evaluate the effectiveness of PCV10 introduction on ultrasound-confirmed pneumonia in 3-35 month-old children using an incident case-control design and to examine the incidence trend of ultrasound-confirmed pneumonia in 3-35 month-old children in the study area before and after PCV10 introduction; and 5) To determine the direct and indirect effects of vaccination status on nasopharyngeal colonization on VT pneumococci among children with pneumonia . This paper presents the methodology. The study will allow us to conduct a comprehensive and robust assessment of the impact of national introduction of PCV10 on pneumococcal disease in Bangladesh.
RESUMO
An estimated 215,000 children died of rotavirus infections in 2013, accounting for 37% of diarrhea-related deaths worldwide, 92% of which occurred in low and lower-middle income countries. Since 2009 the World Health Organization (WHO) recommends the use of rotavirus vaccines in all national immunization programs. This review compares rotavirus vaccine (RV) introductions and vaccine coverage by region, country income status and Gavi-eligibility from 2006-2016. Gross National Income data from the World Bank and surviving infant population from United Nations Population Division was obtained for 2016. Data from WHO were collected on rotavirus vaccine coverage, national immunization schedules, and new vaccine introductions for 2016 while estimated rotavirus deaths were collected for 2013, the last year of available WHO data. As of December 2016, the majority of countries (57%, 110/194) had not introduced universal rotavirus vaccine despite WHO's 2009 recommendation to do so. Countries in the WHO African region had the greatest proportion of introductions (37%, 31/84) by December 2016 and a great majority of these (77%, 24/31) were supported by new vaccine introduction (NVI) grants from Gavi. Almost half (48%) of global introductions were in low and lower-middle income Gavi-eligible and Gavi-graduating countries. Conversely, countries in the Southeast Asia WHO region and those not eligible for Gavi NVI support have been slow to introduce rotavirus vaccine. High-income countries, on average, had poorer rotavirus vaccine coverage compared to low and lower-middle income countries. The over-representation of African countries within the Gavi subset and high estimated rotavirus deaths in these African countries, likely explains why introduction efforts have been focused in this region. While much progress has been made with the integration and implementation of rotavirus vaccine into national immunization programs, 110 countries representing 69% of the global birth cohort had yet to introduce the vaccine by December 2016.

BACKGROUND: In 2013, the US Advisory Committee on Immunization Practices (ACIP) opted against adding meningococcal vaccines to the infant schedule due to poor cost-effectiveness. This raises a policy question: if meningococcal disease is too rare to justify routine vaccination, are there other vaccine-preventable causes of US infant deaths that could be supported? METHODS: We tabulated US infant deaths from 2009-2013 using the CDC WONDER database. These causes of death were then categorized into one of 3 categories: 1) vaccine-preventable using currently available interventions; 2) potentially vaccine-preventable within the next 10 years; and 3) not preventable. RESULTS: From 19.8 million births (3.9 million/year), â¼122,000 infants died (0.62%). Of these, 181 (0.15% of all deaths) were preventable using currently available vaccines, while an additional 779 were categorized as potentially preventable in the next 10 y. By exclusion, 121,040 (99.2%) were judged 'not vaccine-preventable'. Meningococcal deaths contributed at most 0.03% of all infant deaths, but accounted for 17-34% of current vaccine-preventable deaths. CONCLUSIONS: The low number of vaccine-preventable deaths in the US makes it increasingly difficult to justify the introduction of any new infant vaccines.

BACKGROUND: Lack of surveillance systems and accurate data impede evidence-based decisions on treatment and prevention of enteric fever, caused by Salmonella Typhi/Paratyphi. The WHO coordinates a global Invasive Bacterial-Vaccine Preventable Diseases (IB-VPD) surveillance network but does not monitor enteric fever. We evaluated the feasibility and sustainability of integrating enteric fever surveillance into the ongoing IB-VPD platform. METHODOLOGIES: The IB-VPD surveillance system uses WHO definitions to enroll 2-59 month children hospitalized with possible pneumonia, sepsis or meningitis. We expanded this surveillance system to additionally capture suspect enteric fever cases during 2012-2016, in two WHO sentinel hospitals of Bangladesh, by adding inclusion criteria of fever ≥102°F for ≥3 days, irrespective of other manifestations. Culture-positive enteric fever cases from in-patient departments (IPD) detected in the hospital laboratories but missed by the expanded surveillance, were also enrolled to assess completion. Costs for this integration were calculated for the additional personnel and resources required. PRINCIPAL FINDINGS: In the IB-VPD surveillance, 5,185 cases were enrolled; 3% (N = 171/5185) were positive for microbiological growth, of which 55% (94/171) were culture-confirmed cases of enteric fever (85 Typhi and 9 Paratyphi A). The added inclusion criteria for enteric fever enrolled an additional 1,699 cases; 22% (358/1699) were positive, of which 85% (349/358) were enteric fever cases (305 Typhi and 44 Paratyphi A). Laboratory surveillance of in-patients of all ages enrolled 311 additional enteric fever cases (263 Typhi and 48 Paratyphi A); 9% (28/311) were 2-59 m and 91% (283/311) >59 m. Altogether, 754 (94+349+311) culture-confirmed enteric fever cases were found, of which 471 were 2-59 m. Of these 471 cases, 94% (443/471) were identified through the hospital surveillances and 6% (28/471) through laboratory results. Twenty-three percent (170/754) of all cases were children <2 years. Additional cost for the integration was USD 44,974/year, a 27% increase to the IB-VPD annual expenditure. CONCLUSION: In a setting where enteric disease is a substantial public health problem, we could integrate enteric fever surveillance into the standard IB-VPD surveillance platform at a modest cost.

BACKGROUND: Undernutrition below two years of age remains a major public health problem in India. We conducted an evaluation of an integrated nutrition and health program that aimed to improve nutritional status of young children by improving breast and complementary feeding practices over that offered by the Government of India's standard nutrition and health care program. METHODS: In Uttar Pradesh state, through multi-stage cluster random sampling, 81 villages in an intervention district and 84 villages in a comparison district were selected. A cohort of 957 third trimester pregnant women identified during house-to-house surveys was enrolled and, following childbirth, mother-child dyads were followed every three months from birth to 18 months of age. The primary outcomes were improvements in weight-for-age and length-for-age z scores, with improved breastfeeding and complementary feeding practices as intermediate outcomes. FINDINGS: Optimal breastfeeding practices were higher among women in intervention than comparison areas, including initiating breastfeeding within one hour of delivery (17.4% vs. 2.7%, p<0.001), feeding colostrum (34.7% vs. 8.4%, p<0.001), avoiding pre-lacteals (19.6% vs. 2.1%, p<0.001) and exclusively breastfeeding up to 6 months (24.1% vs. 15.3%, p = 0.001). However, differences were few and mixed between study arms with respect to complementary feeding practices. The mean weight-for-age z-score was higher at 9 months (-2.1 vs. -2.4, p = 0.0026) and the prevalence of underweight status was lower at 12 months (58.5% vs. 69.3%, p = 0.047) among intervention children. The prevalence of stunting was similar between study arms at all ages. Coefficients to show the differences between the intervention and comparison districts (0.13 cm/mo) suggested significant faster linear growth among intervention district infants at earlier ages (0-5 months). INTERPRETATION: Mothers participating in the intervention district were more likely to follow optimal breast, although not complementary feeding practices. The program modestly improved linear growth in earlier age and weight gain in late infancy. Comprehensive nutrition and health interventions are complex; the implementation strategies need careful examination to improve feeding practices and thus impact growth. TRIAL REGISTRATION: The trial was registered with ClinicalTrials.gov, NCT00198835.

Despite the licensure of the pneumococcal conjugate vaccine (PCV) in the US and other Western countries for over 14 years, as of September 2014 only 4 South Asian countries were using PCV in their universal immunization program. To generate momentum toward addressing this issue a "South Asia symposium on pneumococcal disease and the promise of vaccines" was organized just prior to the 9th international symposium on pneumococci and pneumococcal diseases held in India recently. Leading scientists, program managers, and decision makers including ministry officials from the region participated in the meeting. The participants discussed available data on pneumococcal disease burden in South Asia, surveillance methods, efficacy and safety of pneumococcal conjugate vaccines (PCV), the status of PCV introduction, programmatic challenges in introducing PCV and available data on the impact of PCV in South Asia and globally. There was a strong consensus that available data on disease burden and the global experience with PCV justified the introduction PCV in all Asian countries in order to accelerate the gains in child survival in the region.

Haemophilus influenzae type B (Hib) vaccine, pneumococcal conjugate vaccine (PCV) and rotavirus (RV) vaccine are available in the private market in India, but, except for Hib in eight states, are not included in India's Universal Immunization Program (UIP). Pediatricians were surveyed about administering non-UIP vaccines. Most give these vaccines to some of their patients (73-83%, depending on vaccine), but few give them to all patients (7-18%). High cost was the most frequently cited barrier (93-96%). Only 10-12% of respondents had concerns about the efficacy of PCV or RV vaccine, and concerns about Hib vaccine efficacy or any vaccine safety issues were rare (1-3%). Practice varied by type of healthcare facility, with pediatricians at government hospitals least likely to administer non-UIP vaccines. Support for the inclusion of all three in the UIP was high (83-95%). Including Hib vaccine, PCV and RV vaccine in India's UIP would be supported by pediatricians and help eliminate the current barrier of high cost of these immunizations.

OBJECTIVE: To evaluate and compare the cost-effectiveness of two strategies for neonatal care in Sylhet division, Bangladesh. METHODS: In a cluster-randomized controlled trial, two strategies for neonatal care--known as home care and community care--were compared with existing services. For each study arm, economic costs were estimated from a societal perspective, inclusive of programme costs, provider costs and household out-of-pocket payments on care-seeking. Neonatal mortality in each study arm was determined through household surveys. The incremental cost-effectiveness of each strategy--compared with that of the pre-existing levels of maternal and neonatal care--was then estimated. The levels of uncertainty in our estimates were quantified through probabilistic sensitivity analysis. FINDINGS: The incremental programme costs of implementing the home-care package were 2939 (95% confidence interval, CI: 1833-7616) United States dollars (US$) per neonatal death averted and US$ 103.49 (95% CI: 64.72-265.93) per disability-adjusted life year (DALY) averted. The corresponding total societal costs were US$ 2971 (95% CI: 1844-7628) and US$ 104.62 (95% CI: 65.15-266.60), respectively. The home-care package was cost-effective--with 95% certainty--if healthy life years were valued above US$ 214 per DALY averted. In contrast, implementation of the community-care strategy led to no reduction in neonatal mortality and did not appear to be cost-effective. CONCLUSION: The home-care package represents a highly cost-effective intervention strategy that should be considered for replication and scale-up in Bangladesh and similar settings elsewhere.

Despite a WHO recommendation in 2009, reaffirmed in 2013, that all countries should consider introducing rotavirus vaccines into their National Immunization Programs, as of June 2013 only 45 have done so. One major consideration appears to have been the costs of the vaccine to countries. Of concern, is that Asian countries have been slow to introduce rotavirus vaccines despite having robust data that could inform the decision-making process. Although decisions on new vaccine introduction are very complex and vary by country and region, economic evaluations are often pivotal once vaccine efficacy and safety has been established, and disease burden documented and communicated. Unfortunately, with private sector list prices of vaccines often used in economic evaluations, rather than a potential public health sector pricing structure, policy-makers may defer decisions on rotavirus vaccine introduction based on the belief that "the vaccine price is too high," even though this might be based on erroneous data. The Pan American Health Organization's Revolving Fund provides one example of how vaccine price can be made more competitive and transparent through a regional tendering process. Other mechanisms, such as tiered pricing and UNICEF procurement, also exist that could help Asian and other countries move forward more quickly with rotavirus vaccine introduction.

OBJECTIVES: To assess the clinical and laboratory features of suspected meningitis to assist in the accurate diagnosis of bacterial meningitis in young Indian children. STUDY DESIGN: Children <2 years of age with clinical suspicion of meningitis were enrolled. Clinical and laboratory information was collected, and cases were classified based on cerebrospinal fluid findings as clinical, aseptic, or probable and confirmed bacterial meningitis. RESULTS: A total of 2564 children with suspected meningitis were enrolled over 45 months; 156 cases of aseptic and 51 cases of bacterial meningitis were identified. Stiff neck and bulging fontanelle were more common in bacterial meningitis (P < .05), but were present in <15% of patients. The World Health Organization and American Academy of Pediatrics classifications for high suspicion of bacterial meningitis were met in 84% and 88% of cases of bacterial meningitis, respectively, but were also present in 54% and 74% cases of aseptic meningitis. Culture and gram stain were positive in 7 (14%) and 4 (8%) cases of bacterial meningitis. CONCLUSIONS: Signs of bacterial meningitis and proposed criteria for high suspicion of bacterial meningitis are non-specific in this population. Standard microbiological tests for bacteria are insensitive in this setting, necessitating highly sensitive methods to identify bacterial meningitis.

OBJECTIVE: To estimate the potential health impact and cost-effectiveness of nationwide Haemophilus influenzae type b (Hib) vaccination in India. STUDY DESIGN: A decision support model was used, bringing together estimates of demography, epidemiology, Hib vaccine effectiveness, Hib vaccine costs, and health care costs. Scenarios favorable and unfavorable to the vaccine were evaluated. State-level analyses indicate where the vaccine might have the greatest impact and value. RESULTS: Between 2012 and 2031, Hib conjugate vaccination is estimated to prevent over 200â000 child deaths (â¼1% of deaths in children <5 years of age) in India at an incremental cost of US$127 million per year. From a government perspective, state-level cost-effectiveness ranged from US$192 to US$1033 per discounted disability adjusted life years averted. With the inclusion of household health care costs, cost-effectiveness ranged from US$155-US$939 per discounted disability adjusted life year averted. These values are below the World Health Organization thresholds for cost effectiveness of public health interventions. CONCLUSIONS: Hib conjugate vaccination is a cost-effective intervention in all States of India. This conclusion does not alter with plausible changes in key parameters. Although investment in Hib conjugate vaccination would significantly increase the cost of the Universal Immunization Program, about 15% of the incremental cost would be offset by health care cost savings. Efforts should be made to expedite the nationwide introduction of Hib conjugate vaccination in India.

BACKGROUND: About a million newborns die each year in India, accounting for about a fourth of total global neonatal deaths. Infections are among the leading causes of neonatal mortality. Care practices immediately following delivery contribute to newborns' risk of infection and mortality. OBJECTIVES: This study examined the association between clean cord care practices and neonatal mortality in rural Uttar Pradesh, India. METHODS: The study used data from a household survey conducted to evaluate a community-based intervention program in two districts of Uttar Pradesh, India. Analysis included data from 5741 singleton live births delivered at home during 2005. The association between clean cord care (clean instrument used to cut cord, clean thread used to tie cord and antiseptics or nothing applied to the cord) and neonatal mortality was estimated using multivariate logistic regression models. RESULTS: Thirty per cent of the study mothers practiced clean cord care. Neonatal mortality rate was significantly lower among newborns exposed to clean cord care (36.5/1000 live births, 95% CI 28.0 to 46.8) than those who did not practice (53.0/1000 live births, 95% CI 46.1 to 60.6). Clean cord care was associated with 37% lower neonatal mortality (OR=0.63; 95% CI 0.46 to 0.87) after adjusting for mother's age, education, caste/tribe, religion, household wealth, newborn thermal care practice and care-seeking during the first week after birth and study arms. CONCLUSIONS: Promoting clean cord care practice among neonates in community-based maternal and newborn care programs has the potential to improve neonatal survival in rural India and similar other settings.

In the context of high neonatal mortality rate (NMR) in developing country settings, a promising strategy for enhancing newborn health is promotion of preventive newborn care practices. We measured the effect of a behaviour-change intervention on perceived neonatal illnesses in rural Uttar Pradesh, India. The study was nested in a cluster-randomized controlled trial of the impact of a package of essential newborn care on NMR. We prospectively enrolled 802 mothers and administered a questionnaire on perceived neonatal morbidities. Regression analysis showed that newborns in the intervention clusters had significantly lower risk of perceived diarrhoea [adjusted relative risk (aRR) 0.67, 95% confidence interval (CI) 0.49-0.90] and skin-related complications [aRR 0.67, 95% CI 0.45-1.00] compared to newborns in the comparison area. Assuming incidence of perceived illnesses is a proxy for actual morbidity rates, we conclude that promotion of preventive care practices through behaviour-change interventions was effective in reducing neonatal morbidities.

OBJECTIVE: To describe the utilization and perceptions of existing neonatal health services in rural Uttar Pradesh, India. DESIGN: A prospective observational study. SETTING: The study was located in Shivgarh, a rural block of Uttar Pradesh, India. PARTICIPANTS: One hundred and fifty-three households that utilized a healthcare provider for their sick neonates. INTERVENTIONS: None. MAIN OUTCOME MEASURE: Perceived neonatal health improvement after utilization of neonatal health services; satisfaction with aspects of neonatal health services: 'overall care', 'interaction with provider', 'waiting time' and 'explanations of immediate care and follow-up care'. RESULTS: Unqualified allopathically oriented providers (UAOPs) were utilized by 110 households (71.8%), while qualified allopathically oriented providers (QAOPs) by 43 households (28.2%). The odds of perceived neonatal health improvement were significantly higher among households utilizing UAOPs (n = 88/110, 80.0%) than those using QAOPs (n = 23/43, 53.5%) [adjusted odds ratio (OR): 3.3, 95% confidence interval (CI): 1.5-7.5]. The median healthcare fee charged was higher for UAOPs (Rs. 25) than those for QAOPs (Rs. 1). Household satisfaction with 'overall care' of neonatal health service was significantly higher among households that utilized UAOPs compared with those that used QAOPs (OR: 2.4, 95% CI: 1.2-5.0). CONCLUSION: Households that utilized UAOPs reported better perceived neonatal health outcomes and higher satisfaction levels than those that used QAOPs, despite higher costs for the former. Future research should assess what dimensions of neonatal care are important to households and identify incentive structures that promote healthcare providers to deliver better perceived care in high-mortality settings such as rural Uttar Pradesh, India.

Rapid uptake of new vaccines can improve health and wealth and contribute to meeting Millennium Development Goals. In the past, however, the introduction and use of new vaccines has been characterized by delayed uptake in the countries where the need is greatest. Based on experience with accelerating the adoption of Hib, pneumococcal and rotavirus vaccines, we propose here a framework for new vaccine adoption that may be useful for future efforts. The framework organizes the major steps in the process into a continuum from evidence to policy, implementation and finally access. It highlights the important roles of different actors at various times in the process and may allow new vaccine initiatives to save time and improve their efficiency by anticipating key steps and actions.
