                     Research and Consultancy

The Institute conducts research and offers consultancy services in four major areas;   (a) National Burden of Disease (b) Health System Performance Assessment (c) Health Care Quality Assurance (d) Health Sector Reforms

National Burden of Disease (NBD)

Epidemiological transition, increasing cost of health care, the unfinished agenda of controlling infectious and parasitic diseases and persisting gaps in access to primary health care, has made the job of health care policy and planning more complex than ever. The complexities of dealing with multifarious health problems, have lead to refocused world wide attention on descriptive epidemiology and burden of disease. The Andhra Pradesh Burden of Disease (APBD) Study was started in 1993, in collaboration with the Administrative Staff College of India (ASCI), immediately after publication of the Global Burden of Disease Study results in the World Bank’s World Development Report, 1993. The study provided an opportunity for a comprehensive estimation of disease burden in AP during the 1990s. Using the case of Andhra Pradesh in India, the study examined available sources of data and describes their usability. Deficiency in availability of local data was highlighted to draw attention to the need for improving vital statistics, cause of death and epidemiological surveillance systems. The Burden of Disease estimates arrived at in this study are of importance from two different policy perspectives. Firstly, National Burden of Disease (NBD) estimates will be of immediate interest to those concerned about health policy of the National or sub-national entity for which the study is made. Secondly, this study has highlighted the need for reliable and valid local data for National Burden of Disease Estimates. Recognizing the importance of NBD estimates in health care and planning, the GOI - Department of Family Welfare, commissioned the IHS to estimate burden of disease among women and children in India. The Institute’s contribution was incorporated as a chapter in the report of the Planning Commission’s working group on Women and Children’s Health. 

Prof. Christopher JL Murray, Director, EIP, World Health Organisation, who has pioneeredGlobal Burden of Disease estimation giving a lecture on "Trends and Challenges in globalhealth and Health Systems", at the IHS on 8th May, 1999.

  

To build national capacity in quantification of disease burden, the Institute has pursued many connected areas of research. These include studies on; (a) Causes of death     (b) Health status measurement (c) Indirect estimation of mortality by smaller areas, and (d) Descriptive epidemiology

Cause of Death Studies 
Reliable statistics on causes of death in a population are essential for setting of priorities in the health sector. Most developed cause of death reporting systems rely on medical certification of cause of death according to the International classification of Diseases (ICD - 10), and have invariably achieved near total coverage. Developing countries like India depend on lay reporting of the cause of death for rural areas, where adequate medical facilities are not available, using a Sample Registration System (SRS). Usability of the cause of death statistics in India is questioned in view of poor coverage, and poor compliance with guidelines for cause of death reporting, coding and classification. Research work on cause of deaths started in IHS around 1993 and is an ongoing activity supported by various sources of funding and when no funding is available, by time contributions from faculty and staff. Work at the Institute lead to identification of Maharashtra and Goa states, where a large number of deaths are medically certified. A pilot study on cause of deaths in rural areas of AP provided some preliminary information about the Survey of Cause of Death (SCD) - Rural statistics. Accordingly the Global Burden of Disease study, 1996 used the Maharashtra medically certified cause of death (MCCD) data to estimate cause of death pattern for urban areas and the applied some corrections to the SCD-Rural data to estimate the same for rural India. Further work at the IHS on cause of death reporting system in India lead to the publication of two landmark articles1 ,2 in the National Medical Journal of India. These articles reviewed the performance of cause of death reporting system in India and argued for its improvement. A small group of researchers in India and abroad got together and offered to collaborate with the Registrar General of India (RGI) to systematically design the SRS based cause of death reporting system. The IHS was a co-founder of this SRS-Collaborative group. Review of the world literature on verbal autopsy and systematic assessment of India’s verbal autopsy based cause of death reporting system contributed to appreciation of the SCD-Rural statistics and appropriate design of the newly introduced SRS based cause of death reporting system. Results of the study to estimate cause of deaths in rural areas of AP contributed to the National Burden of Disease estimation for Andhra Pradesh and has provided more accurate cause of death statistics for policy analysis. The Institute has also developed a computer software for processing of cause of death reports by municipal health offices, state vital statistics offices as well as research and analysis teams.
   
Health Status Measurement
Health status measurement is an important step in quantification of disease burden due to non fatal health outcomes. Ideally, burden of disease estimates should use community valuation of different health states. As community level health state valuation tend to be difficult and time consuming, most disease burden studies use expert rated disability weights. The AP Health State Valuation study conducted by the Institute in 1999 was the first community valuation of a set of health states in a developing country. The study, attempted to measure peoples preferences about various health states. Two distinct sources of assessment was used in measuring people’s opinion. Firstly, a series of workshops was conducted with the educated population from various professional backgrounds. Health state valuation was done using four procedures viz., card sort, Visual Analogue Scale, Time Trade-off & Person Trade-off methods. Second part of the study involved measurement of valuations given by general population through household surveys. Respondents were requested to give their valuations using card sort followed by visual analogue scales. The study had to deal with the unique challenge of communicating health state descriptions to semiliterate, illiterate population. This was overcome by development

of a pictorial description system. This study is an important contribution to theoretical advances in health state valuation. The 6D5L health state description systems developed for this study3 , theoretical and empirical aspects of community based health state valuation, their reliability and validity issues4 were incorporated in the WHO publication on summary measures of population health.
 
Indirect estimation of mortality by smaller areas 
Conventional measures of premature mortality, like Infant Mortality Rate (IMR) continue to play an important role in health policy. Reduction of IMR is an important goal set by the National Health Policy. Currently the Sample Registration System (SRS) is the primary source of IMR estimates in the country. Unfortunately the SRS does not provide IMR estimates for smaller areas below the state level. Availability of IMR estimates for small areas will facilitate identification of areas with very poor population health status and targeting of public health programmes. The District Family Health Survey (DFHS) piloted by the Institute studied the feasibility of generating IMR estimates at the sub district level. This study was conducted in three districts of Andhra Pradesh, Chittoor, Nellore and Mahboobnagar, representative of the three political regions of AP. The indirect methods of estimation such as children ever born (CEB) technique for IMR, and Sisterhood Survival Method for Maternal Mortality Rate (MMR) were used. The sample was selected using a two-stage proportional stratification followed by random selection of clusters within strata assigning probability proportionate to population size. IMR estimates show significant variation in mortality in different districts and revenue divisions. One revenue division in Mahboobnagar district had IMR as high as 125/1000 live births, which is twice as high as the state average IMR of 66 / 1000 live births. We hope that identification of such high mortality risk areas would help in better targeting of public health interventions. The results of this study highlight the need for decentralised area specific planning and implementation of public health programmes.
 
Descriptive Epidemiology

Descriptive epidemiology is about understanding the natural history of diseases, estimation of disease frequency and mapping of known risk factors. These are important contributors to estimation of disease burden. They help in identifying linkages between risk factors and disease burden. For example, the Institute’s study comparing prevalence of morbidity and nutritional status of child labourers in aqua culture industry and other children did not show any significant difference. An exploratory study to identify social, economic and cultural processes that are of relevance for management of asthma5 , revealed that there is a large social and economic burden on account of asthma. The study threw light on the existing social sharing of asthma morbidity and the institution of family as a particularly useful means of the coping up process. The study provided useful insights for the WHO task force on global strategy for asthma management. Government of Andhra Pradesh commissioned the Institute to prepare comprehensive manuals to achieve better control of the gastroenteritis (GE) and malaria situation in the state. Descriptive epidemiology studies for this purpose included analysis of seasonal pattern and geographic localization of gastroenteritis in AP, malaria trend in the state, etc.

The Institute conducted a household survey as part of a collaborative study to develop a predictive model of exposures to indoor air pollution (IAP) from qualitative information about fuel use, and housing characteristics. The study revealed that households using mixed fuels have the highest Respirable Particulate Matter (RSPM) concentrations (732 mg/m3). Households with poor kitchen ventilation had a twofold risk of having high kitchen concentrations of RSPM compared to households with good ventilation. The IHS has been commissioned by Environmental Protection Training & Research Institute (EPTRI) to develop an initial estimation of the health impacts of ambient air pollution in Hyderabad, based on available secondary data. The health effects analysis project is essentially a correlation study, involving the determination of a statistical association between the frequency of a given health outcome and concurrent PM10 concentrations. This task will draw upon existing data on ambient air pollution impacts on mortality and morbidity of selected health endpoints. Economic valuation of health impacts for both indoor and ambient air quality, will also be done using the Human Capital Approach (HCA) method. A study designed to understand the epidemiology of risk factors associated with high level of road traffic accidents in Hyderabad has been recently approved by the ICMR. Causative linkages between accidents and road design, road user behaviour, traffic regulation, and road worthiness of vehicles will be explored.

Health System Performance Assessment (HPA)
Health system performance measurement is important: first as a means of identifying the shortcomings of health systems, as in explaining why countries with similar levels of income fail to achieve similar levels of health; secondly, for providing indicators that allow evaluation of a health system over time. Both these activities in turn could contribute in the future to a pool of evidence that can provide the basis for confirming or rejecting if specific financing and provision mechanisms are particularly appropriate under given socioeconomic conditions. A more efficient health system would mean that more health care services are provided for the same level of resource use. Improving efficacy of health systems through operations research and performance assessment is one of the important objectives of the Institute. Keeping with this objective, the Institute has fostered many research areas such as: (a) Hospital Performance Analysis (b) Patient Satisfaction Surveys (c) Responsiveness Surveys (d) National Health Accounts.
Hospital Performance Analysis
The Institute’s goal is to make public hospitals more efficient and responsive. As people become more aware of the hospital performance analysis they are more sensitive to accept required remedial actions for further improvement. The IHS was commissioned by the AP Vaidya Vidhana Parishad (APVVP) to undertake a performance analysis of APVVP hospitals on monthly basis. Every month hospital activity indicator and service mix data were collected from the APVVP hospitals. Hospital wise performance analysis was done. Each month the Institute’s researchers visited about 20 hospitals to collect qualitative information and to verify data accuracy. The field reports and monthly analysis were furnished to the hospital management. The Institute assisted the APVVP for about three years between July 1998 to 2002. There after the APVVP is doing their performance analysis in-house. Starting May 2002, the Institute has been assisting the government of Maharashtra in improving efficiency and quality of service of hospitals under the Maharashtra Health Systems Development (MHSDP), using performance measurement and analytic techniques on a regular basis. The MHSDP hospital statistics is analysed for its consistency and based on the performance indicators, outlier hospitals are identified. Internal consistency of data is analyzed using a set of consistency indicators and by expert appreciation of the figures. A sub set of hospitals are identified each month for field visit to understand the potential sources of poor performance and to provide on job training to the hospital data compilation personnel.
Patient Satisfaction Survey
Patient satisfaction survey is a reliable yardstick to assess the quality of health care extended by the health care institutions. The aim is to generate statistically accurate estimates of patient’s feed back for each hospital, so that inter hospital comparison is possible. It generates data for theoretical importance and for practical purposes such as planning, administration and evaluation of health care services. The Institute of Health Systems conducted a study on the Demand for services and Satisfaction with the Mauritius Health System. The project was orchestrated by the Burden of Diseases Unit at the Harvard Center for Population and Development Studies (HCPDS). A systematically selected sample of in patients (IP) and out patients (OP) were interviewed using a structured questionnaire. Focus groups were conducted with members drawn from households and members of Local Health Committees (LHC) who were closely associated with the functioning of the peripheral health delivery institutions. The published HCPDS report titled "The Health Sector in Mauritius", contains substantial sections on the Demand and Satisfaction study conducted by IHS. The Institute was commissioned by the AP First Referral Health Systems Project (APFRHSP) to conduct patient satisfaction surveys in APVVP hospitals at half yearly intervals between June 1999 and March 2002. These surveys provide useful feedback on functioning of different areas in the respective hospital and helpful insights about patients’ preference. The Institute brought out five half yearly reports on the survey beginning June 1999. The study on structure and dynamics of private health sector in AP included a patient exit interview component to compare the level of satisfaction among patients attending private and public health care institutions respectively. An early work in this area, is the study of patient satisfaction of Karimnagar district hospital.
 
Responsiveness Surveys

Health system performance involves three discrete aspects: medical, responsiveness and fair financing. The AP Health System Responsiveness Survey measured responsiveness of the health system in AP to individuals’ expectations regarding the non-clinical enhancing aspects of the health system. The survey sought to measure eight distinct aspects of health system responsiveness pertaining to elements related to respect for human beings as individuals, that are largely subjective and judged primarily by the client, and the more objective elements related to how a system meets commonly expressed concerns of patients / clients and their families as consumers of health system. The study provided valuable insights into responsiveness of the health system to patient/client needs and expectations. Respondents in urban areas had better access to health care institutions than those in rural areas. The average time taken for people to access health care was 56 minutes and 142 minutes in urban and rural areas respectively. It was found that people in urban areas have better access to public health care institutions than those in rural areas.

Respondents in rural areas preferred to go to a private provider as they could not rely on the primary health centre for any serious health care need. Of the eight dimensions of health system responsiveness studied (respect for dignity, respect for confidentiality, respect for autonomy over treatment, prompt attention, communication, basic amenities, social support and choice of provider), 53% of the respondents rated prompt attention to their needs as most important. Communication of information relating to health condition and respect of dignity of patient was rated as most important by 23% and 14% of the respondents respectively. Only 3% of the respondents rated choice of provider as most important. The survey found that 36% of the respondents did not seek any health care because they could not afford it. About 16% of the respondents said that they were refused health care because they could not afford it.

 
National Health Accounts (NHA)

National health accounts (NHA) document total health care financing and expenditure within a particular health system. Health expenditure consists of financial outlays that service the health system. NHA trace the resources invested and consumed in the production of health and facilitates further research and meaningful policy analysis.

In the Indian context, state level studies are at least as important as overall national analyses. In some respect, state health accounts (SHA) are more important, because many of the major policy decisions concerning resource allocation to health and social sector are made at the state level. The analysis of government expenditure on health in AP happens to be one of the first contributions 

Prof. William Hsiao, Harvard School of Public Health, deliveringa lecture on "Comparing health systems and their financing.What countries can learn from each other"- 14 April 1993.

towards building up of state health accounts in India. This study covered not only standard medical programs like curative and preventive care, but also health related activities such as primary education, water supply, sewerage, sanitation, housing, and community development. Such an approach has the important advantage of producing a much clearer picture of government’s overall orientation toward social development. The study found that during the 1980s APgovernment expenditure on public health nearly tripled in real terms. This was complemented by large increases in health related expenditure as well. For example, expenditures on primary education more than tripled, and the amount of funds spent on housing and community development increased more than eight fold. This is not to say that everything went well. First referral (district and sub district level) hospitals received inadequate attention relative to urban tertiary hospitals. Too little was invested in training for nurses and paramedical personnel compared with the amounts spent on educating medical doctors. The amount provided for sewerage and sanitation programs was very low. Results of these studies have been published in journals6 ,7 and others8 in addition to the IHS publications. To facilitate appropriate analysis of health expenditure of the state, the Institute has compiled data on public spending on health and related areas from 1980 - 1993. This was one of the first electronic compilation of government budget and accounts data. A software called Government Expenditure Analyst (GEA) was developed to allow researchers analyse expenditure data upto the sub head level. Expertise gained at the IHS in electronic compilation of government budget data contributed to preparation of the first budget data on disk in India. The first Budget Data on Disk of the Andhra Pradesh Government was released by the State Finance Minister in 1998. The IHS was one of the collaborating Institutions contributing to development and delivery of this new service. The Institute is currently developing more comprehensive State Health Accounts for Andhra Pradesh. In addition to health services provided by the government (Central, State and Local Bodies), the study focusses on health care revenues and expenditure of NGO’s, voluntary and charitable organizations, public and private sector firms, social insurance schemes such as CGHS and ESIS,private insurance, households etc. The findings of the study is expected to contribute to the Government of Andhra Pradesh medium term financing strategy for the health sector.
   
Health Care Quality Assurance (HQA)

Quality of care delivered by health care institutions is a matter of public concern. The Institutes research activities in this area started with an early study to assess the need for and designing of an accreditation system. This pilot study asked patients discharged from private hospitals about their experience and concerns of quality of care. There appeared to be some awarenes and felt need for quality assurace in health care. A subsequent study9 of expressions of need for quality assurance revealed that the level of awareness about the need for quality assurance in health, among general public was low. However, legislators, medical professionals, and consumer interest groups are increasingly conscious of the need for quality assurance in health sector. The Institute has been actively studying various aspects of the private health sector, with special emphasis on standards and quality assurance. A study was conducted to ascertain the perceptions and expectations of the women regarding quality of reproductive health care offered in private hospitals of Andhra Pradesh. The Institute then developed standards for selected reproductive health procedures, viz., normal deliveries, Caesarean section, medical termination of pregnancy, etc. Actual quality situation was assessed against these standards using various qualitative research methods, to assess quality gaps in the provision of reproductive health care. During the course of the study on the structure and dynamics of the private health sector in AP, the Institute has developed a framework for assessment of health care quality. An early study sponsored by the government of Andhra Pradesh, documented quality concerns of the users and non users of family planning methods.

Social, cultural, economic and related factors affecting the acceptance of family planning methods were studied. This study has found a positive appreciation of vasectomy by its adopters as opposed to the negative biases of its non adopter males and also females, and also thrown important clues on quality of family welfare that is being provided. A UNICEF sponsored study, conducted in the year 2001, assessed the infrastructure for Emergency Obstetric Care (EmOC) in Medak and Adilabad districts. Effective availability of EmOC equipment and health care personnel such as obstetricians, and anaesthetists were found to be a major hindrance in provision of quality services. The study built up an inventory of private EmOC facilities around primary health centres (PHC) equipped to provide round-the-clock EmOC services. Functional status and adequacy of facilities in PHCs, Area and District Hospitals were assessed. To develop national capacity in health care quality assurance, the Institute has built up a collection literature about accreditation systems in other parts of the world. The Institute’s President visited, in 1992, the Joint Commission for Accreditation of Health Care Organisations (JCAHO) in USA and had a two month attachment in an American hospital to study compliance with accreditation system from the hospital perspective. Another faculty while on a research fellowship with the Harvard University studied the accreditation system in the USA.
 
Health Sector Reform
Health Sector Reform is a sustained process of fundamental change in policies and institutional arrangements of the health sector, usually guided by the government. Any meaningful reform process ought to be based on evidence and information about the current state of affairs, and potential effect of alternative policy choices. Many of the Institute’s research activities take place with the objective of generating evidence and information for health policy. For example, the study of hospital autonomy, documented the experiences of the AP Vaidya Vidhana Parishad in Andhra Pradesh11 . Some studies in this area describe and compare different health systems mainly in the developed (Organisation of Economic Cooperation and Development, OECD) countries12 . Many studies have been taken up to understand the Private Health Sector including both for profit and nonprofit health care institutions.

 An early study taken up by the Institute was about the management of financial resources in voluntary health agencies13 . Insights gained from the Institute’s study of organisation and management of community public trusts and civil society institutions were used to develop systems and procedures for Nandi Foundation, a community public trust based in Andhra Pradesh. The study on social evolution of hospitals and its relevance for health policy was an example of history of health care and its current policy relevance. The IHS was commissioned by the AP First Referral Health Systems Project (APFRHSP), to take stock of the private health sector in Andhra Pradesh and identify appropriate policy choices for their overall development.

A workshop was organised in May 1998, with participants from the private health sector and public health officials. Result of the studies spearheaded by the IHS were presented in the workshop and various issues were discussed. A comprehensive report on the private health sector in AP and policy recommendations regarding the private sector has been brought out. In 1999, the Institute started a more detailed study to understand the structure and dynamics of the private sector in Andhra Pradesh. The study was commissioned by the Government of India, Ministry of Health. This study collected data from within AP and reviewed literature from elsewhere in the world. The study found that there is hardly any difference in terms of efficiency and quality of care between private for profit, non profit and public health care institutions. Public and nonprofit health care institutions are clearly more accessible to the poor.

One advantage of private forprofit health care institutions is their quick response to changing demand for services. The study recommends encouraging nonprofit health care institutions, and development of quality assurance infrastructure. The IHS was commissioned by the Government of AP to prepare a State Action Plan for reproductive services and heath sector reform. Review of the time trend and current status of reproductive and child health in the state, reproductive and child health program implementation in the state, focus group discussion with ANMs and PHC Medical Officers in the state, available results of other studies commissioned by the government in this regard, as well as the states vision 2020 health goals, contributed to the development of a state action plan. Major recommendations in the state action plan include; (a) basic package of services, drugs, equipment, supplies and furniture to be made available at the Sub center; (b) improvement of locational convenience and accessibility of PHCs and sub centres; (c) expansion of a scheme to increase institutional deliveries, using private partnerships, etc. The IHS was appointed as the State Consultant, by the Government of AP for the development of medium term financing strategy for the health sector. The reform strategy is to fulfill the State’s structural adjustment targets pertaining to financing of primary health care. The Institute conducted a strategy development workshop in April 2001 to kick start the strategy development process. The DFID of the Government of United Kingdom which is likely to provide partial financial support for the reform process, appointed Harvard School of Public Health - International Health System Group (IHSG) to continue the strategy development work in a two phase process. In Phase One, the Institute introduced the Harvard IHSG team members to key stake holders, and familiarised them with relevant official documents and literature and provided other inputs gained from our experience in working with the AP health system. In addition, the IHS reviewed existing information and analysis on burden of disease in AP, suggested important gaps in current priorities and highlighted strengths of current priorities from a burden of disease perspective.

Phase two of the exercise involves analysis and projection of the resource envelope for the health sector, development of specific strategies including the priority areas identified in phase one, and formulating a Medium Term Strategy Expenditure Framework in collaboration with the state government. The IHS role during this second phase is to contribute towards preparation of state health accounts for AP. The Institute was assigned the task of developing community health insurance based family health protection plans by the GOI - Department of Family Welfare. The report of the study, presented to the government by end of March, 2003, recommends an income line for health and housing higher than the poverty line, for purposes of administration of state financing of health insurance coverage to families. The benefit package in the proposed family health protection plans include comprehensive ambulatory primary care, and access to first referral hospital services. The plans would mostly use private clinics for the ambulatory care and public or nonprofit providers for hospital services. Minimum quality of service standard have been recommended for clinics. The plans will provide better access to public hospitals and help improve their utilisation. Nonprofit mutual health organisations are envisaged to underwrite the health care coverage risk and administer the plans. The proposal is under active consideration of the government. The Institute has made modest contributions by being available to the Prime Minister’s Office (PMO) and in rendering assistance, according to its capacity. The Institute’s comments on the draft new national health policy was sought. Accordingly a presentation was made at the PMO on 17 Jan 2002. Senior officers from the PMO and various ministries of the GOI were present. Suggestions and comments about expanding the health care coverage to ex-servicemen, sought by the PMO, was submitted. The Institute’s Director is a member of the Task Force on Public Private Partnership, which works from the PMO. Institute has been contributing towards generation of creative ideas and identification of opportunities for public private partnerships to improve public health.
