Analysis of Cutaneous Adverse Drug Reactions at a Tertiary Care Hospital – a Prospective Study

Purpose: To analyze the clinical, pharmacological and economical aspects of the cutaneous adverse drug reactions (ADRs) reported at Civil Hospital, Ahmedabad, India.Methods: A prospective observational study over a period of one and half years (November 2006 to April 2008) was undertaken. Semi-spontaneous reporting along with a review of case record forms were used. The reports were analyzed for clinical pattern, causal drug groups, causality (WHO-UMC criteria), severity (Hartwig and Siegel scale) and preventability (modified Schumock and Thornton criteria). The cost of ADRs was calculated on the basis of hospital expenditure per patient and the amount spent by patients themselves.Results: Out of 143 reports, chemotherapeutic agents (39 %) were the most commonly suspected drugs followed by unknown medicines (29 %). Most of the ADRs were designated as possible or probable (69 %) and moderately severe (96.5 %) in nature. However, 14 – 16 % were definitely preventable. Cost incurred by the hospital was Indian national rupees (INR) 374,255, i.e.,USD 8241. While average cost incurred by outpatients was INR 99 (USD 2.18) and that of hospitalized patients was INR 264 (USD 5.81).Conclusion: A large number of cutaneous ADRs are due to unknown medicines. This calls for strict drug control mechanisms, patient education regarding self-medication and maintenance of prescription records. The cost associated with ADRs is high. ADR monitoring is essential to reduce patient suffering as well as to achieve the substantial savings in health care cost.Keywords: Cutaneous adverse drug reactions, Cost of ADRs, Preventability, Patient educatio

A GIS based transportation model for solid waste disposal – A case study on Asansol municipality

Uncontrolled growth of the urban population in developing countries in recent years has made solid waste management an important issue. Very often, a substantial amount of total expenditures is spent on the collection of solid waste by city authorities. Optimization of the routing system for collection and transport of solid waste thus constitutes an important component of an effective solid waste management system. This paper describes an attempt to design and develop an appropriate storage, collection and disposal plan for the Asansol Municipality Corporation (AMC) of West Bengal State (India). A GIS optimal routing model is proposed to determine the minimum cost/distance efficient collection paths for transporting the solid wastes to the landfill. The model uses information on population density, waste generation capacity, road network and the types of road, storage bins and collection vehicles, etc. The proposed model can be used as a decision support tool by municipal authorities for efficient management of the daily operations for transporting solid wastes, load balancing within vehicles, managing fuel consumption and generating work schedules for the workers and vehicles. The total cost of the proposed collection systems is estimated to be around 80 million rupees for the fixed cost of storage bins, collection vehicles and a sanitary landfill and around 8.4 million rupees for the annual operating cost of crews, vehicles and landfill maintenance. A substantial amount (25 million rupees/yr) is currently being spent by AMC on waste collection alone without any proper storage/collection system and sanitary landfill. Over a projected period of 15 yr, the overall savings is thus very significant.© Elsevie
