The primary objective of this research was to evaluate the effectiveness of a checklist, compared to a smart pump and bar-code verification system, at detecting different categories of errors in intravenous medication administration. To address this objective, a medication administration safety checklist was first developed in an iterative user-centered design process. The resulting checklist design was then used in a high-fidelity simulation experiment comparing the effectiveness of interventions towards two classifications of error: execution and planning errors. Results showed the checklist provided no additional benefit for error detection over the control condition of current nursing practice. Relative to the checklist group, the smart pump and bar-coding intervention demonstrated increased effectiveness at detecting planning errors. Results of this work will this work will help guide the selection, implementation and design of appropriate interventions for error mitigation in medication administration.

An estimated 70,000 preventable medication errors occur in Canada annually, causing up to 23,750 deaths. Medication errors increase when the number of medications being administered increases. Therefore, people with multi-morbidity who take several medications at once are more vulnerable to medication errors. Medication errors can be prevented by developing and managing an efficient healthcare system integrated with technology. Near Field Communication (NFC) technology, in particular, has been shown to improve the quality of health care and increase patient safety. NFC has a powerful ability to identify and track objects such as patients and medications; its identification and tracking abilities give it significant potential especially in detecting drug interaction and drug allergy. The main objective of this thesis is to present a novel solution using NFC-enabled smartphone integrated with NFC application to detect and update drug allergies and drug interactions for people with multi-morbidity during medication administration. / The system has been implemented using Samsung Nexus S smartphone with Android 2.3.6 platform, MIFARE Classic 1K tags, and a database populated with 10 patients’ record and 30 medications. The system was validated for the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), accuracy, and computational and communicational cost.

Background. Medication-related patient injuries (adverse drug events, ADEs) are an important problem in all hospitalised populations; however, the potential for injury is reported to be greater in children than adults. Many ADEs are due to error and therefore could be prevented. Data regarding the risk factors (or predictors) for these events in paediatric inpatients is limited. It was hypothesised that "identification of risk factors for ADEs and medication errors in the paediatric inpatient setting will inform likely prevention strategies". Aims. To determine the frequency, nature and risk factors for ADEs and potential ADEs occurring in a paediatric inpatient population; to assess the vulnerable processes in the neonatal intensive care unit (NICU) medication use process; and to provide recommendations for the targeting of likely prevention strategies. Setting. A general paediatric ward (PW), postnatal ward (PNW) and NICU of a University- affiliated urban general hospital. Design. There were two study components: the medEVENT study which involved identification of actual ADEs and potential ADEs over a twelve week period, through prospective review of medical records, medication charts and administration records along with voluntary and solicited staff report and parent interview; and the FMEA study which used a proactive risk assessment technique, Failure Mode and Effect Analysis (FMEA), to rank all potential failures in the NICU medication use process according to risk. Results. In the MedEVENT study 3160 prescription episodes were reviewed (which represented 520 admissions, 3037 patient-days) and revealed a total of 67 ADEs and 77 potential ADEs. The greatest number of events occurred in NICU with very few events in the PNW. However, paediatric surgical admissions experienced the highest rate of ADEs per 1000 patient-days (80) as compared to medical (65) then NICU admissions (19). Over half of the ADEs were deemed preventable, 38 (57%), with the �more serious� ADEs more likely to be preventable than �not serious� ADEs. The impact on hospital resources was considerable with the cost attributed to extra bed days due to ADEs to be $NZD 50,000. Dosing errors were the most common type of error, particularly when prescribing and administering medications. Antibacterial and narcotic analgesics were commonly implicated, as was the intravenous route of administration. Few events were related to unlicensed use of medications. For ADEs, the major risk factors when analysed by admission, were greater medication exposure and increasing age; by prescription, were increasing age, oral route and narcotics and antibacterial agents; for paediatric ward admission, were increasing age and increased length of stay; and for NICU admission, no major risk factors emerged. For potential ADEs, the major risk factors when analysed by admission were greater medication exposure; by prescription, were junior prescriber, intravenous route, narcotics and antibacterials; for paediatric ward admission, were junior prescriber and narcotics; and for NICU admission were antibacterials, electrolytes and umbilical venous catheter administration. Neither ADEs nor potential ADEs were associated with unlicensed use of medicines or high alert status drugs. The FMEA study identified 72 potential failures in the NICU medication use process with 193 associated causes and effects. Multiple failures were possible in the process of �prescribing medication� and in the process of �preparation of medication for administration�. The highest ranking issues were found to occur at the administration stage. Common potential failures related to errors in the dose, timing of administration, infusion pump settings and route of administration. Conclusions. Analysis of the risk factors of ADEs and potential ADEs found that the most vulnerable processes were when prescribing and when preparing a medicine for administration; especially when involving narcotic and antibacterial agents and for children with greater medication exposure Strategies that selectively target these high risk areas are therefore likely to have the greatest impact on preventing drug-related injuries in hospitalised children.

Introdução: Erros envolvendo medicamentos ocorrem frequentemente em hospitais, possuem natureza multidisciplinar e podem ocorrer nas várias etapas da terapia medicamentosa. Objetivos: Avaliar a seriedade, o tipo e os medicamentos envolvidos nos erros de medicação notificados no Hospital de Clínicas de Porto Alegre. Verificar a qualidade do conteúdo das notificações obtidas pelos instrumentos de notificação disponíveis na Instituição. Classificar os erros através de árvore de decisão para atos inseguros, quando aplicável. Métodos: Foram analisadas notificações comunicadas por escrito em 2010-2011. A amostra foi composta por 165 notificações. Os erros identificados foram classificados de acordo com a seriedade, o tipo e a classe farmacológica. Foram analisadas 114 notificações, nas quais um erro de fato ocorreu, quanto à qualidade das informações contidas. A qualidade foi avaliada considerando-se os itens preconizados pela ANVISA. A árvore de decisão para atos inseguros foi utilizada para verificar fatores individuais ou sistêmicos nos erros notificados. Resultados: Apesar de um maior número de notificações comunicadas em 2011, comparativamente a 2010, não houve uma alteração significativa no perfil de seriedade destes eventos. Os erros ocorridos ao longo do processo geraram, em algumas situações, novos erros de medicação associados. O tipo de erro mais frequente foi o de prescrição (40%). Nas 114 notificações de erro foram citados 122 medicamentos. O conteúdo das notificações demonstrou que todos itens preconizados pela ANVISA estavam presentes, mas informados em frequências diferentes. A caracterização dos atos inseguros foi realizada com as 30 notificações comunicadas por ficha padronizada pela Instituição. Constatou-se que 19 ações se enquadram como possíveis violações por imprudência e 9 ações, como erros induzidos pelo sistema. Conclusão: A segurança dos pacientes depende do processo de comunicação, do registro adequado das informações e do monitoramento propriamente dito no uso dos medicamentos. / Background: Errors involving medications occur frequently in hospitals, they are multidisciplinary and can occur at many stages of drug therapy. Objectives: Assess the seriousness, the type and drugs involved in medication errors reported on Hospital de Clínicas de Porto Alegre. Checking the quality of the reports obtained by the notification tools available in the institution. Classifying errors by decision tree for unsafe acts, when applicable. Methods: The sample consisted of 165 notifications. The errors identified were classified according to the seriousness, type and pharmacological class. We analyzed 114 notifications, in which an error has occurred, as to the quality of information. The quality was evaluated considering the items recommended by ANVISA. The decision tree for unsafe acts was used to identify individual or systemic factors in the errors reported. Results: Although a greater number of notifications reported in 2011 compared to 2010, there was no significant change in the profile of seriousness of these events. The errors occurred during the process, have in some situations, new medication errors associated with it. The most common type of error is the prescription error (40%). In 114 reports, 122 medication errors were cited. The content of notifications showed that all items recommended by ANVISA were present, but reported at different frequencies. The characterization of unsafe acts were performed with 30 notifications from a standardized form by the institution. We verified that 19 actions were classified as potential violations recklessness and 9 actions, such as errors induced by the system. Conclusion: Patient safety depends on the communication process, the suitable recording of information and monitoring the appropiate use of medicines.

O objeto de estudo é o preparo e a administração de medicamentos pela enfermagem por via intravenosa. O objetivo geral foi discutir as consequências, para os pacientes, dos erros encontrados a partir do preparo e da administração de medicações de uso intravenoso pela enfermagem, no ambiente hospitalar. Os objetivos específicos foram determinar os grupos medicamentosos e os medicamentos envolvidos em erros; e identificar o tipo e frequência desses erros que ocorrem no preparo e administração de medicamentos intravenosos pela enfermagem. Trata-se de uma pesquisa com desenho transversal de natureza observacional, sem modelo de intervenção. Foi desenvolvida em um hospital público, da rede sentinela, do Rio de Janeiro onde foram observados técnicos de enfermagem preparando e administrando medicamentos intravenosos, em três setores: Unidade de Terapia Intensiva, Clínica Médica e Clínica Cirúrgica. Foram observadas 367 doses preparadas e 365 doses administradas, totalizado 732 doses, à luz de 14 categorias. Para cada dose observada havia somente duas possibilidades: certo ou errado. Com relação ao perfil das medicações, os grupos prevalentes foram os antimicrobianos com 176 doses (24,04%), seguidos dos antissecretores com 149 doses (20,36%) e analgésicos com 126 doses (17,21%). Anestésicos e anticonvulsivantes foram os menos observados. Todas as categorias foram divididas em dois grupos: os com potencial de dano para o paciente e os com potencial para alterar a resposta terapêutica do medicamento. Na etapa do preparo, no grupo com potencial de dano, as categorias foram: não troca as agulhas com 88,77% de erro; não desinfecção de ampolas (80,27%) e não faz limpeza de bancada (77,26%). Nas categorias não usa máscara e não identifica o medicamento, não foram encontrado erros. Para o grupo com potencial para alterar a resposta terapêutica, as categorias foram: hora errada (57,26%) e dose errada (6,58%). Na etapa da administração, no grupo com potencial de dano ao paciente, as categorias foram: não confere o medicamento com 96,73% de erro, não avalia flebite (87,47%), não avalia a permeabilidade (86,38%) e não confere o paciente (70,57%). Para o grupo com potencial para alterar a resposta terapêutica, a categoria hora errada apresentou 69,75% de erro; em dose errada e via errada não foi evidenciado erro. Percebeu-se que, nas duas etapas, o grupo prevalente foi o com potencial de dano paciente. Porém, no grupo com potencial para alterar o resultado terapêutico do medicamento, a categoria a hora errada foi a que, provavelmente, apresentou maiores prejuízos para o paciente. Considerando-se que o preparo e administração de medicamentos são umas das maiores responsabilidades da enfermagem e que os erros podem causar danos aos pacientes, sugere-se repensar o processo de trabalho da enfermagem e investir mais em questões que envolvam a segurança com a terapia medicamentosa. / The overall objective was to discuss the consequences for patients about the found errors from the intravenous medications preparation and administration by nurses in the hospital. The specific objectives were to determine the errors referring to involved drugs, their groups, type, and frequency in the intravenous medications preparation and administration by nurses. This is a survey of cross-sectional observational, without intervention model. It was developed in a public hospital, belonging to the sentinel network of Rio de Janeiro, where nursing technician were observed, preparing and administering intravenous medicines in three sectors: the Intensive Care Unit, Medical Clinic, and Surgical Clinic. There were observed 367 prepared doses and 365 administered, totaling 732 in the light of 14 categories. For each observed dose, there were only two possibilities, right or wrong. Regarding to the medication profile, the prevalent groups were antimicrobials with 176 doses (24.04%), followed by antisecretory medicines with 149 doses (20.36%), and analgesics with 126 doses (17.21%). Anesthetics and anticonvulsants were the least observed. All categories were divided into two groups: those with damage potential to the patient and others with potential to alter the drug therapeutic response. In the preparation stage, in the group with the damage potential, the categories were "do not exchange needles" with 88.77% of error, "no disinfection of ampoules (80.27%), and "do not clean bench" (77.26%). In the categories "not wearing a mask" and "do not identify the drug, no errors were found. For the group with potential to alter the therapeutic response, the categories were "wrong time" (57.26%) and "wrong dose" (6.58%). In the administration phase, in the group with damage potential to the patient, the categories were "do not confer the drug", with 96.73% of error, "do not evaluate phlebitis (87.47%), "do not measure permeability (86.38%) and "do not check the patient" (70.57%). For the group with potential to alter the therapeutic response, the categories "wrong time" had 69.75% of error; in "wrong dose and "wrong way" no errors were evidenced. It was noticed that in both steps the group with potential harm to the patient prevailed. However, in the group with potential to alter the medication therapeutic efficacy, the category wrong time was probably the one causing more damage to the patient. Considering that the medications preparation and administration are one of the nursing biggest responsibilities, and the errors can cause damage to patients, it is suggested rethinking nursing work process and investing more on issues involving the safety of drug therapy.

Por estas razões, é imperativa a adoção de estratégias que permitam reduzir os erros de medicação e aumentar a qualidade e a segurança dos cuidados prestados à saúde dos pacientes hospitalizados. Este artigo visa a apresentar uma análise crítica dos principais resultados de pesquisa sobre os erros de medicação dentro das instituições de saúde, esperando contribuir para o melhor conhecimento do problema e a tomada das iniciativas necessárias para preveni-los. Foram pesquisadas as bases de dados do Cumulative Index to Nursing & Allied Health (CINAH), PubMed, Web of Knowledge, Scopus e Science Direct, no período compreendido entre 1990 a 2013, usando as palavras-chaves: erros de medicação, administração de medicamentos, cuidados à saúde, cuidados de enfermagem e eventos adversos. Os estudos mostram que embora a falha humana seja importante de ser investigada, a análise do contexto no qual o erro de medicação ocorreu é uma das questões-chave na abordagem do erro em saúde, pois, em geral, um erro de medicação, está muito mais ligado às deficiências ou inadequações do ambiente físico e/ou a falhas dos processos organizacionais e psicossociais do sistema de saúde, do que propriamente na falha do indivíduo. Entre os fatores de risco para os erros de medicação, relacionados a variáveis ambientais estão incluídos: inexistência/deficiência de instalações ou inadequado uso do espaço, desorganização da estocagem de medicamentos, inexistência/inadequação de equipamentos, e iluminação imprópria e/ou excesso de ruídos no ambiente de trabalho. Entre os fatores de risco de origem organizacional e psicossocial estão incluídos: deficiências de recursos humanos, sobrecarga de trabalho, desvios de ...
