Determining Medication Errors in an Adult Intensive Care Unit.

INTRODUCTION: Research addressing the costs of Medication errors (MEs) is still scarce despite issues related to patient safety having significant economic and health impacts, making it imperative to analyze the costs and adverse events related to MEs for a better patient, professional, and institutional safety. AIM: To identify the number of medication errors and verify whether this number was associated with increased hospitalization costs for patients in an Intensive Care Unit (ICU). METHOD: This retrospective cross-sectional cohort study evaluated secondary data from patients' electronic medical records to compile variables, create a model, and survey hospitalization costs. The statistical analysis included calculating medication error rates, descriptive analysis, and simple and multivariate regression. RESULTS: The omission error rate showed the highest number of errors per drug dose (59.8%) and total errors observed in the sample (55.31%), followed by the time error rate (26.97%; 24.95%). The omission error had the highest average when analyzing the entire hospitalization (170.40) and day of hospitalization (13.79). Hospitalization costs were significantly and positively correlated with scheduling errors, with an increase of BRL 121.92 (about USD $25.00) (95% CI 43.09; 200.74), and to prescription errors, with an increase of BRL 63.51 (about USD $3.00) (95% CI 29.93; 97.09). CONCLUSION: We observed an association between two types of medication errors and increased hospitalization costs in an adult ICU (scheduling and prescription errors).

Risk factors for medication errors in the electronic and manual prescription.

OBJECTIVE: to compare electronic and manual prescriptions of a public hospital of Brasilia, identifying risk factors for the occurrence of medication errors. METHOD: descriptive-exploratory, comparative and retrospective study. Data collection occurred from July 2012 to January 2013, using an instrument for the review of the information contained in medical records related to the medication process. A total of 190 manual and 199 electronic records composed the sample, with 2027 prescriptions each. RESULTS: compared to the manual prescription, a significant reduction was observed in the risk factors after implantation of the electronic prescription, in items such as "lack of the form of dilution" (71.1% to 22.3%) and "prescription with brand name" (99.5% to 31.5%). Conversely, the risk factors "no check" and "lack of CRM of the prescriber" increased. The lack of the allergy registration and the occurrences related to medication were the same for both groups. CONCLUSION: generally, the use of the electronic prescription system was associated with a significant reduction in risk factors for medication errors, concerning the following aspects: illegibility, prescription with brand name and presence of essential items that provide a safe and effective prescription.

RESUMO Objetivo: comparar as prescrições eletrônicas e manuais de um hospital público do Distrito Federal, identificando os fatores de risco para ocorrência de erros de medicação. Método: Estudo descritivo-exploratório, comparativo e retrospectivo. A coleta de dados ocorreu no período de julho de 2012 a janeiro de 2013, através de instrumento para revisão das informações referentes ao processo de medicação contidas em prontuários. Integraram a amostra 190 prontuários manuais e 199 eletrônicos, com 2027 prescrições cada. Resultados: na comparação com a prescrição manual, observou-se redução significativa dos fatores de risco após implantação da eletrônica, em itens como "falta da forma de diluição" (71,1% e 22,3%) e "prescrição com nome comercial" (99,5%/31,5%), respectivamente. Por outro lado, os fatores de risco "não checar" e "falta de CRM do prescritor" aumentaram. A ausência de registro de alergia e as ocorrências em relação aos medicamentos são equivalentes para os dois grupos. Conclusão: de maneira geral, a utilização do sistema de prescrição eletrônica foi associada à redução significativa dos fatores de risco para erros de medicação nos seguintes aspectos: ilegibilidade, prescrição com nome comercial e presença de itens essenciais que proporcionam prescrição eficaz e segura.

RESUMEN Objetivo: comparar las prescripciones electrónicas y manuales de un hospital público del Distrito Federal, identificando los factores de riesgo para la ocurrencia de errores de medicación. Método: estudio descriptivo exploratorio, comparativo y retrospectivo. La recolección de datos ocurrió en el período de julio de 2012 a enero de 2013, a través de instrumento para revisión de las informaciones referentes al proceso de medicación contenidas en fichas médicas. Integraron la muestra 190 fichas médicas manuales y 199 electrónicas, con 2.027 prescripciones cada una. Resultados: en la comparación con la prescripción manual, se observó reducción significativa de los factores de riesgo después de la implantación de la electrónica, en ítems como "falta de la forma de dilución" (71,1% y 22,3%) y "prescripción con nombre comercial" (99,5%/31,5%), respectivamente. Por otro lado, los factores de riesgo "no verificar" y "falta de CRM del prescriptor" aumentaron. La ausencia de registro de alergia y las ocurrencias en relación a los medicamentos son equivalentes para los dos grupos. Conclusión: de manera general, la utilización del sistema de prescripción electrónica fue asociada a reducción significativa de los factores de riesgo para errores de medicación en los siguientes aspectos: ilegibilidad, prescripción con nombre comercial y presencia de ítems esenciales que proporcionan prescripción eficaz y segura.
