Recently, as the variety of medicines being used has increased, so has the incidence of adverse drug reactions (ADRs) and the range of different types of reactions experienced.It is thus important to determine causative medicines as soon as possible and prevent them being administered to patients again.
With these objectives in mind, we established an ADR reporting system in April 2002.Under the system, doctors report ADRs to pharmacists who determine whether to classify the causative medicine as being contraindicated or subject to careful administration.A drug causing an allergic reaction is considered to be contraindicated and a drug for which an ADR depends on the dosage is considered to require careful administration.If a medicine is classified as being contraindicated, it cannot be administered to the patient in whom it caused an ADR again.
Drug information is also shared with patients based on the ADR reports.When an ADR is serious, the pharmacist reports it to the Ministry of Health, Labour and Welfare and the pharmaceutical company.By enabling us to collect and manage ADR information efficiently, the system has been playing an important role in the prevention of ADRs in our hospital.However, we need to further improve it so that we can identify the causative medicines with greater accuracy.
