Pharmaceutical care in transplant patients in a university hospital: pharmaceutical interventions

A descriptive and prospective study was conducted on the pharmaceutical care in the post-transplant outpatient clinic of Hospital Universitario Walter Cantidio of Universidade Federal do Ceará (HUWC/UFC), in Fortaleza- Ceará in the period of April to October of 2011. The aim of the present study was to describe the pharmaceutical interventions performed in a Pharmaceutical Care service structured in the liver and kidney transplant outpatient clinic of an academic hospital. The Pharmaceutical interventions (PI) were classified according to Sabater et al.(2005), with significance based on Riba et al.(2000) and the Negative Outcomes associated with Medication (NOM) established at the Third Consensus of Granada. Statistical analyses were performed using the Epi Info v.3.5.1 program and hypothesis tests were done with the SigmaPlot v.10.0 program. A chi-squared (X²) test was utilized for statistical analysis of the sample. A total of 97 patients were followed, where 54 problems related to medications were identified and 139 PI performed. The main PI were in education of the patient about treatment (n=111; 80%) (p<0.05), while the significance of all interventions were appropriate, where 83.4% (n=116) of PI performed in the study period were shown to be "significant" (p<0.05). Through pharmaceutical care, the pharmacist is capable of monitoring the pharmacotherapeutic treatment and intervening when necessary, while being part of the multiprofessional team caring for the transplant patient.

Trata-se de um estudo de descritivo e prospectivo, realizado durante o atendimento farmacêutico nos ambulatórios de pós-transplante do Hospital Universitário Walter Cantídio da Universidade Federal do Ceará (HUWC/UFC), em Fortaleza-Ceará no período de abril a outubro de 2011. O presente trabalho objetiva apresentar as intervenções farmacêuticas realizadas em um serviço de Atenção Farmacêutica (ATENFAR) estruturado nos ambulatórios do transplante hepático e renal de um Hospital Universitário. As intervenções farmacêuticas (IF) foram classificadas de acordo com Sabater et al.(2005), a significância baseadas em Riba et al.(2000) e os Resultados Negativos associados a Medicamentos (RNM) fundamentados no Terceiro Consenso de Granada. As análises estatísticas foram realizadas no programa Epi Info v.3.5.1 e os testes de hipótese foram feitos no programa SigmaPlot v.10.0. O teste estatístico utilizado para análise da amostra foi o qui-quadrado (X²). Foram acompanhados 97 pacientes, identificados 54 problemas relacionados aos medicamentos e realizadas 139 intervenções farmacêuticas. As principais IF realizadas foram na educação do paciente sobre o tratamento (n=111; 80%) (p<0,05), já enquanto a significância todas as intervenções foram apropriadas, sendo que 83,4% (n=116) das IF realizadas no período do estudo mostram ser "significantes" (p<0,05). O farmacêutico, através do exercício da ATENFAR, é capaz de monitorar o tratamento farmacoterapêutico e intervir, quando necessário, integrando-se a equipe multiprofissional no cuidado ao paciente transplantado.

[Analysis of similar drug labeling: potential medication errors]. / Análise da rotulagem de medicamentos semelhantes: potenciais erros de medicação.

OBJECTIVE: This study aimed to examine drug packaging and labeling, identifying similarities among them that may lead to medication errors, which may occur by unintentional substitution, in different sectors of the pharmacy of a university hospital in northeastern Brazil. METHODS: Cross-sectional observational study, which included 300 pharmaceutical presentations (150 pairs) that were photographed from May to December 2010. Concordance analysis of data related to the pictures of possibly similar packaging and labels was validated using the Kappa index. RESULTS: Of all drugs evaluated (n = 150), about 43% of "possibly similar drugs" were in the central pharmacy (n = 65) and were related to small-volume parenteral solutions. The strength of interobserver agreement in the category "very similar to each other" was considered "satisfactory" (Kappa = 0584) in 90.66% of the drugs evaluated (n = 136). The overall Kappa analysis of the study was 0.488. Variables with statistical significance were: "same color label or packaging", with the respective percentages for both primary and secondary packaging (52%-44%), p = 0.028; the variable "same color of drug presentation" obtained similar values and statistical significance to the previous variable; for the variable "same arrangement of words", the values found for both packages were close to 50%, p = 0.001; and for the variable "same color of the words", the percentages were: (50.7% - 44%) (p = 0.008). CONCLUSION: Our results indicate similarities related to the labeling of drugs with potential for errors, especially in dispensing, storage, and administration if preventive measures are not adopted.

Análise da rotulagem de medicamentos semelhantes: potenciais erros de medicação / Analysis of similar drug labeling: potential medication errors

OBJETIVO: Este trabalho objetivou analisar as embalagens e rótulos de medicamentos, identificando semelhanças entre os mesmos que possam conduzir a erros de medicação passíveis de ocorrer por troca, em diferentes setores da farmácia de um hospital universitário do nordeste do Brasil. MÉTODOS: Estudo observacional e transversal, que abrangeu 300 apresentações farmacêuticas, sendo (150 duplas) fotografadas no período de maio a dezembro de 2010. A análise de concordância dos dados referente às fotos de embalagens e rótulos possivelmente semelhantes foi validada utilizando o índice Kappa. RESULTADOS: Do total de medicamentos avaliados (n = 150), cerca de 43 por cento dos "possivelmente semelhantes" estavam na farmácia central (n = 65) e se relacionaram a soluções parenterais de pequeno volume. A força de concordância interobservadores na categoria "muito semelhante entre si" foi considerada "satisfatória" (índice Kappa = 0,584) em 90,66 por cento dos medicamentos avaliados (n = 136). A análise do Kappa geral do estudo foi de 0,488. As variáveis com significância estatística foram: "mesma cor do rótulo ou embalagem", com os respectivos percentuais, tanto para embalagens primárias como secundárias (52 por cento-44 por cento), com p = 0,028. A variável "mesma cor das apresentações farmacêuticas" obteve valores e significância estatística semelhantes à variável anterior. Quanto à variável "mesma disposição dos dizeres", os valores encontrados para ambas as embalagens foram próximas a 50 por cento, com p = 0,001 e, para a variável "mesma cor dos dizeres", os percentuais encontrados foram: (50,7 por cento-44 por cento) (p = 0,008). CONCLUSÃO: Nossos resultados identificaram semelhanças relativas à rotulagem de medicamentos com potencial, principalmente, para erros de dispensação, armazenamento e administração se medidas preventivas não forem adotadas.
