[Preventable adverse drug effects at an emergency department].

OBJECTIVE: To determine the incidence and evaluate the preventability of adverse drug events (ADE) associated with visits to the Emergency Department at our hospital and subsequent hospital admissions. METHODS: A six-month observational study was conducted at an Emergency Department in a University Teaching Hospital (October 15th, 1995, to April 15th, 1996). The parameters influencing the preventability were identified by means of a multivariate logistic regression analysis. RESULTS: A total of 776 ADEs (2.25%) were detected out of a total of 33,975 patients attended at the Emergency Department; 178 patients were admitted. A total of 322 cases (43.3%) were classified as preventable and were graded as mild (37.1%), moderate (32.5%), severe (27.4%), and fatal (3%). The logistic regression analysis showed that preventability was related to drugs with a narrow therapeutic index (NTI) (OR: 10.12; 95%CI: 5.36-19.07), type A ADE (OR: 4.65; 95%CI: 2.79-7.78), age > or = 65 years (OR: 3.04; 95%CI: 2.13-4.34) and self-administered medication (OR: 2.2; 95%CI: 1.32-3.65). Among admitted patients, oral anticoagulants, NSAIDs, digoxin, diuretics, and insulin caused adverse events which were considered as preventable in more than 50% of cases. The errors most frequently associated with preventable ADEs included inappropriate therapy monitoring (22.5%), increased doses with NTI drugs (22.3%), absence of preventive therapy (14.3%), excessive dose according to patient's characteristics (13.4%), and inappropriate self-administered medication (10%). CONCLUSIONS: The incidence of preventable ADEs (medication errors) is high and its severity is higher than that of non-preventable ADEs. A prompt development and implementation of measures leading to avoiding prescription errors and inappropriate treatment monitoring, the factors identified as responsible for preventable ADEs, is clearly warranted.

[Prevalence and factors associated with preventable adverse drug events leading to hospital admission].

OBJECTIVE: To determine the prevalence of adverse drug events (ADEs) leading to hospital admission, and to assess those that were potentially preventable, identifying the drug classes involved, types of medication errors and the factors associated with the preventable ADEs. METHOD: An observational study, over a six-month period on ADEs that lead or contributed to hospital admissions, carried out in 6 medical units of a university hospital. RESULTS: A total of 259 ADEs were detected of which 159 (61.4%) were assessed to be potentially preventable. The overall prevalence of admissions directly due to ADEs was of 6.7% (177) and to preventable ADEs of 4.7% (125). In addition, 82 ADEs that contributed to hospital admission were detected. Risk factors for preventable ADEs were patient age of 65-74 (OR = 1.40) or = 75 years (OR = 2.70), self-medication (OR = 15.55), prescription in primary care (OR = 2,88) and the use of narrow therapeutic index drugs (OR = 2.40). The drug classes most frequently involved in preventable ADEs were NSAID and aspirin (32.5%), diuretics (15.3%), antihypertensives (9.1%) and digoxin (7.7%). Inadequate therapy monitoring (20.7%), prescription of an inappropriate drug (15.7%) or of an excessive dosage (12.0%), lack of preventive treatment (15.7%), non-adherence (10.6%) and inappropriate self-medication (10.1%) were the most commonly identified types of error. CONCLUSIONS: A high proportion (4.7%) of hospital admissions are caused by potentially preventable ADEs. Results obtained justified the need to adopt measures directed at improving surveillance and prescription quality, and educating patients in safe drug use, focusing especially on older patients and narrow therapeutic index drugs.

[Medication errors: standarizing the terminology and taxomany. Ruiz Jarabo 2000 grand results].

OBJECTIVE: To make available a consistent terminology and taxonomy that permits standardization in medication error detection, analysis, classification, and recording. METHODS: A working group consisting of healthcare professionals from four hospitals of varying characteristics was established to develop the terminology and the taxonomy, which was validated through a qualitative analysis of 423 medication errors registered in the participating hospitals. RESULTS: A document with a terminology and a taxonomy for classifying medication errors is presented. CONCLUSIONS: This document will facilitate analysis of the information collected on incidents caused by medication, and will allow comparisons to be made among data gathered in different kinds of settings. In addition, it will be a useful tool for medication safety committees in hospitals in their efforts to set up internal reporting programs designed to identify shortcomings in their medication use systems and to adopt effective measures to reduce the incidence of medication errors.
