副作用回避を経済的に評価する指標としての副作用にかかる費用に関する調査研究 その１． 医薬品による重篤な皮膚障害にかかる費用（急性期入院医療機関別包括評価（ＤＰＣ）と医薬品副作用被害救済制度を利用した概算）

Abstract

Adverse drug reactions cause increases in medical care expenditure. To investigate this, we estimated the annual cost of the treatment of serious drug-induced dermopathy based a report by the Ministry of Health Labour and Welfare (MHLW).We used the “relief system for sufferers of adverse drug reactions” and “Diagnosis Procedure Combination” to calculate the cost of treating each patient for serious drug-induced dermopathy, which worked out at 337, 470 yen/patient. In fiscal 2000, 302 cases of serious drug-induced dermopathy were reported so the total cost of treating this condition was estimated at 101, 915, 940 yen. This result shows that the economic cost of treating adverse drug reactions is very large.
