Neonatal outcomes at a subdistrict hospital in north India.

Subdistrict hospitals form the first referral level facilities for essential newborn care services. However, there is a paucity of information on the pattern of neonatal admission and outcomes at this level. The objective of this study was to describe the spectrum of neonatal mortality at a subdistrict hospital. The study was conducted at a 50-bed hospital at Ballabgarh in northern India. The data of the neonates born in this hospital (inborns) and those admitted with sickness after being delivered at home (outborns) were separately analysed for the period 1994-1999. The main outcomes of interests were incidence, distribution, and primary causes of neonatal mortality. Of 6746 inborns and 385 outborns admitted (total 7,137) there were 56 deaths (0.8 per cent) and 38 (0.6 per cent) referrals among inborn and 70 deaths (18.2 per cent) and 37 (9.6 per cent) referrals among outborns. The deaths or referral rates among inborn for different weight groups were 27.7 per cent for < 1,500 g, 7.2 per cent for 1500-1999 g, 1.2 per cent for 2,000-2,499 g, and 0.6 per cent for weight > or = 2,500 g. Most deaths under 7 days of age were related to prematurity [41 per cent (28/69)] and birth asphyxia [38 per cent (26/68)], while those aged between 7 and 27 days were mostly due to sepsis [91 per cent (42/46)]. The results of this study indicate that babies with a birthweight above 1,500 g have a good outcome at this level. Deaths under 7 days of age were mostly due to birth asphyxia and prematurity, while those after 7 days were almost entirely due to sepsis. Referral is an important outcome at this level of service.

Estimation of mortality and morbidity due to strokes in India.

In order to control the stroke problem, its magnitude should be assessed. India is ranked among the countries where the information on stroke is minimal. We decided to review the information available in order to estimate the mortality and morbidity due to stroke in India. Information was collected through electronic search, hand search and contact with experts. Each article was reviewed for relevance and epidemiological rigor. The demographic data were as derived from published government figures. The prevalence from individual studies was pooled and weighted based on sample size. Analysis was done separately for males and females at 10-year intervals (20 years onwards). A total of 7 studies was located, but 2 were discarded. All were done in rural areas except 2 which also included urban areas. The prevalence was estimated as 203 per 100,000 population above 20 years amounting to a total of about 1 million cases. The male to female ratio was 1.7. Around 12% of all strokes occurred in population below 40 years. The estimation of stroke mortality was seriously limited by the method of classification of cause of death in the country. The best estimate derived was 102,000 deaths; which represented 1.2% of total deaths in the country. There is need to initiate steps to collect data on morbidity and mortality due to stroke in the country as a first step towards control measures.

Microvessel density and p53 overexpression in young women with breast cancer: a case-control study.

Several reports have indicated that young women (less than 40 years of age) with breast cancer have a worse prognosis than older women. We performed a case-control study in order to confirm this observation and to determine whether this was attributable to increased microvessel density (MVD) or p53 expression. Twenty-six young women (cases) with stage I-III breast cancer that had adequate paraffin-embedded archival tissue were identified by the Montefiore Medical Center Tumor Registry over a 24-year period. For each case, two or three control subjects at least 40 years of age or older were selected from the registry and matched for nodal status and tumor size. Immunohistochemistry was performed for MVD and p53 overexpression. A Cox proportional hazard model was performed to examine the influence of age, MVD, p53 overexpression, and recognized prognostic factors on disease-free and overall survival. There were 26 cases (median age, 36 years) and 72 controls (median age, 64 years). The groups were well matched for known prognostic variables. There was no significant difference in p53 overexpression or MVD in the cases and controls. In multivariate analysis, the only features associated with an increased risk of recurrence included young age (hazard ratio [HR] = 2.49; 95% confidence interval [CI]: 1.18-5.25; P = 0.02) and positive lymph nodes (HR = 2.44; 95% CI: 1.12-5.30; P = 0.02). We have confirmed previous reports demonstrating a worse prognosis for women younger than 40 years with invasive breast cancer but found no correlation between young age and MVD or p53 overexpression when adjusted for other variables.

Scale for identification of "at risk" families for underfive deaths.

India currently has an infant mortality rate (IMR) of 73 and aims to reach 60 per 1000 live births by 2000 A.D. The "at risk" approach which has been traditionally used for Maternal and Child Health services could help to reduce costs. The main objective of the study was to identity socio-demographic "risk factors" at family level for underfive deaths and assess the validity and efficiency of a risk index scale for this purpose. A computerised database on about 71,000 individuals in 28 villages in Ballabgarh Block exists since 1987. All the underfive deaths in the study area during the period 1991-95 were compared with age and sex matched controls on socio-demographic variables. All variables which were found significant at 10% level were taken in for logistic regression. The variables found significant were used to construct a ten point scale. This scaling system was applied to all the families with an underfive child during the two year period 1996-97. Validity and efficiency of this approach was calculated. A total of 849 cases and their age and sex matched controls were studied. The variables which were significantly associated with risk of underfive deaths were: not received measles vaccine (2.19; 1.58-3.04), history of sibling death (2.03; 1.19-3.45), maternal illiteracy (1.86; 1.23-2.81), never used a contraceptive (1.59; 1.17-2.14), having more than 4 children (1.46; 1.04-2.05). About 40% of houses were labelled as high risk. The sensitivity and specificity were around 60%. The improvement in efficiency by the risk approach was 33%. Risk approach is helpful in identifying families who are at greater risk of having underfive deaths. It results in a modest increase in the efficiency of services.

"Development" is not essential to reduce infant mortality rate in India: experience from the Ballabgarh project.

BACKGROUND: India aims to reduce the infant mortality rate (IMR) to below 60 per 1000 live births by 2000. IMR is higher in northern India as compared with south Indian states like Kerala. Any further reduction in IMR needs identification of new strategies. The Ballabgarh project with an IMR of 36 in 1997 can help identify such strategies. OBJECTIVE: To see the trend in reduction of neonatal mortality rate (NNMR) and IMR at the Ballabgarh project, compare it with Kerala and rural India's trend and look at the causes of neonatal and infant mortality. DESIGN: The Comprehensive Rural Health Services Project, Ballabgarh, run by the All India Institute of Medical Sciences, covered an estimated population of 70,079 in 1997. The health care delivery system is on the national pattern. All the deaths are identified during the house visits by the male workers. The cause of death is ascertained by the health assistant based on the symptomatology at the time of death. RESULTS: The trends in reduction of IMR for Ballabgarh, Kerala and rural India are roughly parallel with the IMR of Ballabgarh lying somewhere in between the two. However, the NNMR of Ballabgarh (10.6 in 1996) was comparable to Kerala's NNMR (10.9 in 1992). The proportion of infant deaths occurring during the neonatal period had fallen from 50% in the early seventies to 30% during 1996-97. In 1992-1994, 33.8% of all neonatal deaths were attributable to low birth weight and 37.3% to infective causes. Acute respiratory infection and diarrhoea continue to be the chief cause of postneonatal mortality. CONCLUSION: It is possible to bring down neonatal mortality before postneonatal mortality. The Kerala model, which focuses on social development, may not apply to northern India for sociocultural reasons.

Economic evaluation of water iodization program in Thailand.

In Thailand, iodine deficiency disorders (IDD) are endemic in 57 out of 75 provinces with an estimated 15 million people at risk of IDD. A three pronged control program with iodized salt, iodized water and iodized oil capsules is being implemented. The water iodization program is both school based and household based. In the household, the residents are given iodine solution, two drops of which is to be added to 10 l of drinking water. In the schools, in addition to this method, an iodinator is used. This releases a fixed amount of iodine into the drinking water. This study examines the cost of the water iodization program in Thailand for the year 1996 in terms of cost per beneficiary, cost per microg iodine consumed daily and cost per goiter person years averted. We used a discount rate of 5%. Field visit and interviews of health personnel from Ministry to village level were conducted to gather primary data. Review of existing papers and reports of the Department of Health, Government of Thailand was done for secondary data. The costs included the capital cost of equipments, initial training and the recurrent costs of potassium iodate, proportional salaries of personnel involved, monitoring and communication activities. The cost per beneficiary of school based iodinator method (US$ 0.72) and school based drop method (US$ 0.64) were similar and much higher than the household based approach (US$ 0.12). The cost per microg of iodine consumed daily was ten times higher in the school based approach (US$ 0.01) compared to the household approach (US$ 0.001). The cost per goiter case averted for the whole strategy of water iodization was US$ 194.50. Water iodization appears to be a low cost intervention. However, the need for behavioral modification raises the issue of long term sustainability.

Effect of highly active antiretroviral therapy on the incidence of HIV-associated malignancies at an urban medical center.

The widespread use of highly active antiretroviral therapy (HAART) since 1996 has led to a substantial decline in morbidity and mortality in patients infected with HIV, although its effect on the incidence of HIV-associated malignancies is unknown. We retrospectively reviewed the annual number of outpatient visits to our HIV clinic, inpatient admissions for HIV disease, and first admissions for patients with cancer and HIV disease at our center between 1990 and 1997. Between 1990 and 1995, there was a progressive increase in the annual number of admissions for HIV disease and HIV-associated cancers that paralleled the increasing HIV clinic volume. In 1997, however, the annual number of first admissions for Kaposi's sarcoma (KS) and non-Hodgkin's lymphoma compared with 1995 decreased by 36% and 63%, respectively, despite a continued increase in the annual number of HIV clinic visits. Similar declines were also noted in the number of new cases of biopsy-confirmed KS and primary central nervous system (CNS) lymphoma. In contrast, there was no decrease in the number of first admissions for patients with HIV infection and other cancers not typically associated with HIV infection. These findings suggest a declining incidence of HIV-associated malignancies since the introduction of HAART.

Impact of HIV/AIDS on the national economy of India.

BACKGROUND INFORMATION: Human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) is a major public health problem in India. In general, it affects mainly young people who are at their most productive part of life. Despite initial fears that AIDS will be disastrous for the economy, recent experience and estimations have shown that there is a need for reappraisal of its economic impact on society. RESEARCH QUESTION: From the viewpoint of the society of India, what is the total cost and equivalent annual cost of HIV infections for the period 1986-1995 (10 years) in India? METHODS: Type of analysis: Cost-descriptive based on predictive modelling cohort analysis using human capital approach. A discount rate of 5% was used. The cost of HIV infections include (i) loss of productivity among HIV patients due to sickness and death, (ii) productivity loss due to caregivers of AIDS patients, and (iii) cost of management of AIDS patients. To estimate the loss of productivity due to premature death attributable to AIDS, a life table approach using two cohorts, one with and one without HIV/AIDS infection at assumed rates was used. The demographic data of 1991 census were used. The difference in the person-years lived in the two scenarios gave the person-years lost due to HIV/AIDS. This was calculated separately for rural and urban areas. To convert this to monetary terms, national per capita income for 1992-93 of Rs. 5529 was used. The data on the days of inpatient care and the cost of management of AIDS patients were based on currently available data and 'expert opinion'. We analysed, using three different sets of assumptions for determination, the low, medium and high estimates of the impact of HIV/AIDS in India. Some of the costs were not included in the present analysis: (i) use of antiviral AZT, (ii) cost of retraining of new workforce, (iii) cost of strengthening of health care system, (iv) cost of research and development, (v) cost of communication activities, (vi) cost of prevention of vertical transmission, and (vii) the intangible cost of pain and suffering to the patients and their families. RESULTS: The total cumulative number of HIV-infected persons in India until 1995 was estimated to be 1.5 million (low estimate), 2.5 million (medium estimate) and 4.5 million (high estimate). The estimated total annual cost (in billion Rupees) of HIV/AIDS in India under low, medium and high assumptions was 6.73, 20.16 and 59.19, respectively. Cost of treatment of AIDS and loss in productivity were the two major components of the cost. CONCLUSIONS: The estimated annual cost of HIV/AIDS appears to be about 1% of the GDP of India if based on high assumptions. However, as mentioned earlier, all costs of HIV have not been taken into account. Its significance has to be assessed in the context of annual growth of GDP (3.5%) and cost of other major diseases in India.
