Comparative Study
Use of the logistic organ dysfunction system to study mortality in an Indian intensive care unit.
Mortality in Indian intensive care units has not been well studied. Scoring systems are used to predict mortality of patients admitted to such units. Some scoring systems predict hospital mortality while others predict mortality in intensive care units. We used the logistic organ dysfunction system to study the hospital and intensive care unit mortalities in our intensive care unit. ⋯ Our intensive care unit mortality rate is comparable to the western hospital mortality rate. However, after transfer of patients out of the unit, the hospital mortality is higher.

Microcytosis is a common red cell change seen in anaemias of varied aetiology. These include iron deficiency, thalassaemia, chronic disease and sideroblastic anaemias. The microcytosis of heterozygous beta-thalassaemia needs to be distinguished from non-thalassaemic microcytosis for its role in thalassaemia control. Red cell indices derived from automated red cell analysers have been used to discriminate between microcytic patients with a high probability of thalassaemia minor from those with a low probability. There is a controversy on the choice of red cell indices to be used and the cut-off values for this distinction, because the prevalence of iron deficiency as a cause of non-thalassaemic microcytosis is variable. Since no Indian study using receiver operator characteristic (ROC) curves was available to determine the above, we conducted this study. ⋯ In countries with a high prevalence of iron deficiency, cut-off values for red cell indices should be recalculated using ROC curves.

With the increase in life expectancy, prevalence of impairments and disabilities are expected to increase in India. However, there have been very few studies to estimate the magnitude of the problem in rural India. This is essential, if appropriate rehabilitation services are to be planned in the country. ⋯ Utilizing the rural field practice areas of medical colleges for collection of data on issues of national health importance would not only strengthen the health system in the country but also improve medical education. There is a need for a comprehensive preventive, promotive, curative and rehabilitative approach to disabilities in India.
