Scope for rotavirus vaccination in India: revisiting the scientific evidence.
Rotavirus vaccines have been developed to prevent deaths resulting from severe diarrhea of rotavirus origin. The use of vaccines as an intervention at scale to prevent and control the burden of rotavirus diarrhea is supported by the argument that prevailing public health measures such as hygiene and sanitation, breast feeding and use of ORS have failed to prevent severe dehydration resulting from diarrhea. The article reviews the existing evidence on the rationale of using rotavirus vaccine as against the feasibility of scaling it up in developing countries like India. The vaccines currently available may not cover the strains circulating in Indian population. The diversity of Rotavirus infection in the country is tremendous and since the safety, immunogenicity and efficacy data has not been collected for India, there is first a need to conduct studies to measure the extent of protection and cross-protection provided by the available vaccines for local strains, before venturing into Rotavirus vaccination program. The potential benefits of immunization have to be first vetted against the risks involved by the policymakers and other stakeholders
Sample size and power analysis in medical research
Among the questions that a researcher should ask when planning a study
is "How large a sample do I need?" If the sample size is too small,
even a well conducted study may fail to answer its research question,
may fail to detect important effects or associations, or may estimate
those effects or associations too imprecisely. Similarly, if the sample
size is too large, the study will be more difficult and costly, and may
even lead to a loss in accuracy. Hence, optimum sample size is an
essential component of any research. When the estimated sample size can
not be included in a study, post-hoc power analysis should be carried
out. Approaches for estimating sample size and performing power
analysis depend primarily on the study design and the main outcome
measure of the study. There are distinct approaches for calculating
sample size for different study designs and different outcome measures.
Additionally, there are also different procedures for calculating
sample size for two approaches of drawing statistical inference from
the study results, i.e. confidence interval approach and test of
significance approach. This article describes some commonly used terms,
which need to be specified for a formal sample size calculation.
Examples for four procedures (use of formulae, readymade tables,
nomograms, and computer software), which are conventionally used for
calculating sample size, are also give
Landscaping teaching and training of urban health as a part of health professional education in India
Introduction
India’s urban population will be doubled from 377 million in 2011 to 915 million in 2050. Such rapid urban growth may lead to several problems by affecting the economy, environment and the society at large. These problems further affect the health vulnerability in urban areas. Thus, there exists a need for health workforce equipped with the knowledge and skills to meet the urban health challenges.
Objectives
To undertake the landscaping of teaching and training of urban health as a part of health professional courses and to undertake mapping of specific training programmes related to urban health in India.
Methodology
A curriculum scan of various health professional courses in India ranging from medicine, dentistry, allied health, Ayurveda, Yoga and Naturopathy, Unani, Siddha and Homoeopathy (AYUSH), nursing to public health was undertaken related to teaching and training of urban health. An exclusive search was also carried out for identifying urban health-specific training programmes being offered in India.
Results
As per the curriculum scan, current health professional courses being offered in India have a very little focus on urban health. It was observed that various cross-cutting issues related to urban health are not adequately addressed in the current curricula. Also the curricula of these health professional courses have not clearly spelt out the desired urban health competencies. Few institutions in India offer short-term training programmes specific to urban health issues
Burden of Severe Pneumonia, Pneumococcal Pneumonia and Pneumonia Deaths in Indian States: Modelling Based Estimates.
The burden of severe pneumonia in terms of morbidity and mortality is unknown in India especially at sub-national level. In this context, we aimed to estimate the number of severe pneumonia episodes, pneumococcal pneumonia episodes and pneumonia deaths in children younger than 5 years in 2010. We adapted and parameterized a mathematical model based on the epidemiological concept of potential impact fraction developed CHERG for this analysis. The key parameters that determine the distribution of severe pneumonia episode across Indian states were state-specific under-5 population, state-specific prevalence of selected definite pneumonia risk factors and meta-estimates of relative risks for each of these risk factors. We applied the incidence estimates and attributable fraction of risk factors to population estimates for 2010 of each Indian state. We then estimated the number of pneumococcal pneumonia cases by applying the vaccine probe methodology to an existing trial. We estimated mortality due to severe pneumonia and pneumococcal pneumonia by combining incidence estimates with case fatality ratios from multi-centric hospital-based studies. Our results suggest that in 2010, 3.6 million (3.3-3.9 million) episodes of severe pneumonia and 0.35 million (0.31-0.40 million) all cause pneumonia deaths occurred in children younger than 5 years in India. The states that merit special mention include Uttar Pradesh where 18.1% children reside but contribute 24% of pneumonia cases and 26% pneumonia deaths, Bihar (11.3% children, 16% cases, 22% deaths) Madhya Pradesh (6.6% children, 9% cases, 12% deaths), and Rajasthan (6.6% children, 8% cases, 11% deaths). Further, we estimated that 0.56 million (0.49-0.64 million) severe episodes of pneumococcal pneumonia and 105 thousand (92-119 thousand) pneumococcal deaths occurred in India. The top contributors to India's pneumococcal pneumonia burden were Uttar Pradesh, Bihar, Madhya Pradesh and Rajasthan in that order. Our results highlight the need to improve access to care and increase coverage and equity of pneumonia preventing vaccines in states with high pneumonia burden
Assessment of Special Care Newborn Units in India
The neonatal mortality rate in India is high and stagnant. Special Care Newborn Units (SCNUs) have been set up to provide quality level II newborn-care services in several district hospitals to meet this challenge. The units are located in some remotest districts where the burden of neonatal deaths is high, and access to special newborn care is poor. The study was conducted to assess the functioning of SCNUs in eight rural districts of India. The evaluation was based on an analysis of secondary data from the eight units that had been functioning for at least one year. A cross-sectional survey was also conducted to assess the availability of human resources, equipment, and quality care. Descriptive statistics were used for analyzing the inputs (resources) and outcomes (morbidity and mortality). The rate of mortality among admitted neonates was taken as the key outcome variable to assess the performance of the units. Chi-square test was used for analyzing the trend of case-fatality rate over a period of 3-5 years considering the first year of operationalization as the base. Correlation coefficients were estimated to understand the possible association of case-fatality rate with factors, such as bed:doctor ratio, bed:nurse ratio, average duration of stay, and bed occupancy rate, and the asepsis score was determined. The rates of admission increased from a median of 16.7 per 100 deliveries in 2008 to 19.5 per 100 deliveries in 2009. The case-fatality rate reduced from 4% to 40% within one year of their functioning. Proportional mortality due to sepsis and low birthweight (LBW) declined significantly over two years (LBW <2.5 kg). The major reasons for admission and the major causes of deaths were birth asphyxia, sepsis, and LBW/prematurity. The units had a varying nurse:bed ratio (1:0.5-1:1.3). The bed occupancy rate ranged from 28% to 155% (median 103%), and the average duration of stay ranged from two days to 15 days (median 4.75 days). Repair and maintenance of equipment were a major concern. It is possible to set up and manage quality SCNUs and improve the survival of newborns with LBW and sepsis in developing countries, although several challenges relating to human resources, maintenance of equipment, and maintenance of asepsis remain
Mapping of MPH programs in terms of geographic distribution across various universities and institutes of India—A desk research
BackgroundLandscaping studies related to public health education in India do not exclusively focus on the most common Masters of Public Health (MPH) program. The field of public health faces challenges due to the absence of a professional council, resulting in fragmented documentation of these programs. This study was undertaken to map all MPH programs offered across various institutes in India in terms of their geographic distribution, accreditation status, and administration patterns.MethodologyAn exhaustive internet search using various keywords was conducted to identify all MPH programs offered in India. Websites were explored for their details. A data extraction tool was developed for recording demographic and other data. Information was extracted from these websites as per the tool and collated in a matrix. Geographic coordinates obtained from Google Maps, and QGIS software facilitated map generation.ResultsThe search identified 116 general and 13 MPH programs with specializations offered by different universities and institutes across India. India is divided into six zones, and the distribution of MPH programs in these zones is as follows, central zone has 20 programs; the east zone has 11; the north zone has 35; the north-east zone has 07; the south zone has 26; and the west zone has 17 MPH programs. While 107 are university grants commission (UGC) approved universities and institutes, only 46 MPH programs are conducted by both UGC approved and National Assessment and Accreditation Council (NAAC) accredited universities and institutes. Five universities are categorized as central universities; 22 are deemed universities; 51 are private universities; and 29 are state universities. Nine are considered institutions of national importance by the UGC, and four institutions are recognized as institutions of eminence. All general MPH programs span 2 years and are administered under various faculties, with only 27 programs being conducted within dedicated schools or centers of public health.ConclusionThe MPH programs in India show considerable diversity in their geographic distribution, accreditation status, and administration pattern
Assessment of Special Care Newborn Units in India

Should Sputum Smear Examination Be Carried Out at the End of the Intensive Phase and End of Treatment in Sputum Smear Negative Pulmonary TB Patients?
The Indian guidelines on following up sputum smear-negative Pulmonary tuberculosis (PTB) patients differ from the current World Health Organization (WHO) guidelines in that the former recommends two follow up sputum examinations (once at the end of intensive phase and the other at the end of treatment) while the latter recommends only one follow up sputum smear microscopy examination, which is done at the end of the intensive phase. This study was conducted to examine if there was any added value in performing an additional sputum smear examination at the end of treatment within the context of a national TB program
A study of organizational versus individual needs related to recruitment, deployment and promotion of doctors working in the government health system in Odisha state, India
Background
An effective health workforce is essential for achieving health-related new Sustainable Development Goals. Odisha, one of the states in India with low health indicators, faces challenges in recruiting and retaining health staff in the public sector, especially doctors. Recruitment, deployment and career progression play an important role in attracting and retaining doctors. We examined the policies on recruitment, deployment and promotion for doctors in the state and how these policies were perceived to be implemented.
Methods
We undertook document review and four key informant interviews with senior state-level officials to delineate the policies for recruitment, deployment and promotion. We conducted 90 in-depth interviews, 86 with doctors from six districts and four at the state level to explore the perceptions of doctors about these policies.
Results
Despite the efforts by the Government of Odisha through regular recruitments, a quarter of the posts of doctors was vacant across all institutional levels in the state. The majority of doctors interviewed were unaware of existing government rules for placement, transfer and promotion. In addition, there were no explicit rules followed in placement and transfer. More than half (57%) of the doctors interviewed from well-accessible areas had never worked in the identified hard-to-reach areas in spite of having regulatory and incentive mechanisms. The average length of service before the first promotion was 26 (±3.5) years. The doctors expressed satisfaction with the recruitment process. They stated concerns over delayed first promotion, non-transparent deployment policies and ineffective incentive system. Almost all doctors suggested having time-bound and transparent policies.
Conclusions
Adequate and appropriate deployment of doctors is a challenge for the government as it has to align the individual aspirations of employees with organizational needs. Explicit rules for human resource management coupled with transparency in implementation can improve governance and build trust among doctors which would encourage them to work in the public sector
Why women choose to give birth at home: a situational analysis from urban slums of Delhi
Objectives: Increasing institutional births is an important strategy for attaining Millennium Development Goal -5. However, rapid growth of low income and migrant populations in urban settings in low-income and middle-income countries, including India, presents unique challenges for programmes to improve utilisation of institutional care. Better understanding of the factors influencing home or institutional birth among the urban poor is urgently needed to enhance programme impact. To measure the prevalence of home and institutional births in an urban slum population and identify factors influencing these events. Design: Cross-sectional survey using quantitative and qualitative methods. Setting: Urban poor settlements in Delhi, India. Participants: A house-to-house survey was conducted of all households in three slum clusters in north-east Delhi (n=32 034 individuals). Data on birthing place and sociodemographic characteristics were collected using structured questionnaires (n=6092 households). Detailed information on pregnancy and postnatal care was obtained from women who gave birth in the past 3 months (n=160). Focus group discussions and in-depth interviews were conducted with stakeholders from the community and healthcare facilities. Results: Of the 824 women who gave birth in the previous year, 53% (95% CI 49.7 to 56.6) had given birth at home. In adjusted analyses, multiparity, low literacy and migrant status were independently predictive of home births. Fear of hospitals (36%), comfort of home (20.7%) and lack of social support for child care (12.2%) emerged as the primary reasons for home births. Conclusions: Home births are frequent among the urban poor. This study highlights the urgent need for improvements in the quality and hospitality of client services and need for family support as the key modifiable factors affecting over two-thirds of this population. These findings should inform the design of strategies to promote institutional births
