A systematic review examining the characteristics of users of NHS patient medicines helpline services, and the types of enquiries they make.

BACKGROUND AND OBJECTIVE: Patient medicines helpline services (PMHS) are available from some National Health Service Trusts in the UK to support patients following their discharge from hospital. The aim of this systematic review was to examine the available evidence regarding the characteristics of enquirers and enquiries to PMHS, in order to develop recommendations for service improvement. METHODS: Searches were conducted using Medline, Embase, Cumulative Index of Nursing and Allied Health Literature, Scopus, and Web of Science, on 4 June 2019. Forward and backward citation searches were conducted, and grey literature was searched. Studies were included if they reported any characteristics of enquirers who use PMHS, and/or enquiries received. Study quality was assessed using the Axis tool. A narrative synthesis was conducted, and where appropriate, weighted means (WMs) were calculated. Where possible, outcomes were compared with Hospital Episode Statistics (HES) data for England, to establish whether the profile of helpline users may differ to that of hospital patients. RESULTS: Nineteen studies were included (~4362 enquiries). Risk of bias from assessed studies was 71%. Enquirers were predominantly female (WM=53%; HES mean=57%), elderly (WM=69 years; HES mean=53 years) and enquired regarding themselves (WM=72%). Out of inpatient and outpatient enquirers, 50% were inpatients and 50% were outpatients (WM). Six of 15 studies reported adverse effects as the main enquiry reason. Two of four studies reported antimicrobial drugs as the main enquiry drug class. From two studies, the main clinical origin of enquiries were general surgery and cardiology. Across six studies, 27% (WM) of enquiries concerned medicines-related errors. CONCLUSIONS: Our findings show that PMHS are often used by elderly patients, which is important since this group may be particularly vulnerable to experiencing medicines-related issues following hospital discharge. Over a quarter of enquiries to PMHS may concern medicines-related errors, suggesting that addressing such errors is an important function of this service. However, our study findings may be limited by a high risk of bias within included studies. Further research could provide a more detailed profile of helpline users (eg, ethnicity, average number of medicines consumed), and we encourage helpline providers to use their enquiry data to conduct local projects to improve hospital services (eg, reducing errors).

Work overload is related to increased risk of error during chemotherapy preparation.

PURPOSE: Chemotherapy preparation units face peaks in activity leading to high workloads and increased stress. The present study evaluated the impact of work overloads on the safety and accuracy of manual preparations. METHOD: Simulating overwork, operators were asked to produce increasing numbers of syringes (8, 16, and 24), with markers (phenylephrine or lidocaine), within 1 h, in an isolator, under aseptic conditions. Results were analyzed using qualitative and quantitative criteria. Concentration deviations of < 5%, 5%-10%, 10%-30%, and >30% from the expected concentration were considered as accurate, weakly accurate, inaccurate, and wrong concentrations, respectively. RESULTS: Twenty-one pharmacy technicians and pharmacists carried out 63 preparation sessions (n = 1007 syringes). A statistically significant decrease in the manufacturing time for one syringe was observed when workload increased (p < 0.0001). Thirty-nine preparation errors were recorded: 30 wrong concentrations (deviation > 30%), 6 mislabeling, 2 wrong diluents, and 1 wrong drug. There was no statistically significant difference in the mean concentration accuracy of final preparations across the three workloads. The overall error rate increased with the number of preparations made in 1 h: 1.8% for 8 preparations, 2.7% for 16 preparations, and 5.4% for 24 preparations (p < 0.05). CONCLUSION: Although pharmacy technicians and pharmacists were able to increase production speeds with no effect on mean concentration accuracy under stressful conditions, there were greater probability errors being made. These results should encourage actions to spread workloads out over the day to avoid peaks in activity.

Clinical oncology pharmacist: Effective contribution to patient safety.

Management and prevention of problems related to oncology drugs are particularly important due to the excessive cost, high toxicity, and narrow therapeutic index of the antineoplastic drugs, in addition to the patients' state of health. Therefore, the presence of the pharmacist as a member of the multidisciplinary team is essential to contribute to patient safety. In this work, the interventions performed were identified, quantified, and classified to characterize the work of the clinical oncology pharmacist. This is a prospective and quantitative study, conducted over a period of six months in the outpatient oncology and chemotherapy clinic of the University Hospital of the University of Campinas, Brazil. A total of 3526 medical prescriptions were evaluated for the 780 patients seen and, among these prescriptions, 220 (6.24%) contained errors, representing 6.24% of the total number. The most common error was dose-related with 79 (22.83%) cases of overdosing. Wrong-patient medication error was the least reported (0.29%). Thirty drugs were involved in the pharmaceutical interventions, Carboplatin and Ondansetron being the most frequent. Thirteen types of potential errors were evaluated according to the method proposed by Cardinal and Fernandes. Two (15.38%) included interventions of indication, contraindication, and therapeutic efficacy of a drug. Five of them (38.46%) are related to the treatment regimen, and two (15.38%) were related to prevention of potential adverse events. Four interventions (30.77%) concerned technical interventions in injectable drugs such as dilution, compatibility, and administration time. Of the 346 interventions performed, 1 (0.29%) was classified as potentially lethal, 114 as serious (32.95%), 140 as significant (40.46%), and 91 as minor (26.30%).

Environmental variables and errors in the preparation and administration of medicines / Variables ambientales y errores en la preparación y administración de medicamentos / Variáveis ambientais e erros no preparo e administração de medicamentos

ABSTRACT Objective: to identify the relationship between environmental factors and errors in the preparation and administration of antibacterial. Method: an observational, cross-sectional study conducted between August and December, 2014 in two clinical units. The sample consisted of 265 doses of medication, observed in different shifts that through a form had the environmental conditions of noise, illumination, humidity, temperature and physical space measured in the preparation and administration stages. Results: the physical dimension for the preparation was inadequate in one unit (3.8m2), and the items illumination, temperature and noise were extremely oscillating in the three shifts and in the two clinics, with averages generally higher than the recommended for the hospital environment, however, variations in illumination and noise were not statistically significant to cause dose errors or erroneous medicine choice (p> 0.05). Conclusion: the environmental variables analyzed may favor medication errors in both the preparation and administration stages.

RESUMEN Objetivo: identificar la relación entre los factores ambientales y los errores de preparación y administración de antibacterianos. Método: estudio observacional, transversal, realizado entre agosto y diciembre de 2014 en dos unidades clínicas. La muestra fue compuesta de 256 dosis de medicamentos, observadas en diferentes turnos, que por medio de un formulario tuvieron las condiciones ambientales de ruido, iluminación, humedad, temperatura y espacio físico medidos en las etapas de preparación y administración. Resultados: la dimensión física para la preparación fue inadecuada en una unidad (3,8m2), y los elementos iluminación, temperatura y ruido fueron extremadamente oscilantes en los tres turnos y en las dos clínicas, con medias generalmente por encima de lo recomendado para el ambiente hospitalario. Sin embargo, las variaciones de iluminación y ruido no fueron estadísticamente significativas para provocar errores de dosis o de elección errónea del medicamento (p>0,05). Conclusión: las variables ambientales analizadas pueden favorecer errores de medicación tanto en la etapa de preparación como en la de administración.

Conclusão: as variáveis ambientais analisadas podem favorecer erros de medicação tanto na etapa de preparo quanto na administração.

Development of a 'ready-to-use' tool that includes preventability, for the assessment of adverse drug events in oncology.

Background Adverse drug events (ADEs) occur frequently in oncology and justify continuous assessment and monitoring. There are several methods for detecting them, but the trigger tool method seems the most appropriate. Although a generic tool exists, its use for ADEs in oncology has not been convincing. The development of a focused version is therefore necessary. Objective To provide an oncology-focused trigger tool that evaluates the prevalence, harm, and preventability in a standardised method for pragmatic use in ADE surveillance. Setting Hospitals with cancer care in France. Method The tool has been constructed in two steps: (1) constitution of an oncology-centred list of ADEs; 30 pharmacists/practitioners in cancer care from nine hospitals selected a list of ADEs using a method of agreement adapted from the RAND/UCLA Appropriateness Method; and (2) construction of three standardised dimensions for the characterisation of each ADE (including causality, severity, and preventability). Main outcome measure The main outcome measure was validation of the tool, including preventability criteria. Results The tool is composed of a final list of 15 ADEs. For each ADE, a 'reviewer form' has been designed and validated by the panel. It comprises (1) the trigger(s), (2) flowcharts to guide the reviewer, (3) criteria for grading harm, and (4) a standardised assessment of preventability with 6-14 closed sentences for each ADE in terms of therapeutic management and/or prevention of side-effects. Conclusion A complete 'ready-to-use' tool for ADE monitoring in oncology has been developed that allows the assessment of three standardised dimensions.

Drug-related problems identified during geriatric medication review in the community pharmacy.

Background In line with the changing role of community pharmacists, we describe here a standardised procedure for detecting DRPs in elderly patients for use in community pharmacies. Objectives The primary aim was to describe the number and type of DRPs identified by community pharmacists in elderly patients. Secondary aims were to determine the number and type of associated pharmacist interventions (PIs) that were transmitted to the prescribers, and to identify risk factors associated with the occurrence of a PI. Setting Community pharmacies. Methods In this prospective, multicentre study, pharmacists received patients aged 65 and over. During a 30-min interview with patients who agreed to participate, patient characteristics were recorded such as age, weight, height, frailty (using the Short Emergency Geriatric Assessment grid), estimated renal function and compliance with treatment assessed by the Girerd scale. Main outcome measure DRPs characteristics. Results A total of 892 patients agreed to participate in 55 pharmacies. Among them 334 DRPs were identified and were associated with 259 PIs. Eighty-nine PIs of 259 were sent to the prescribing physicians; 70 (78%) were implemented by the general practitioner. Factors associated with the occurrence of a DRP are compliance problems [odds ratio (OR) = 1.8, 95% confidence interval (CI) (1.26-2.58)], frailty [OR = 1.3, 95% CI (1.01-1.66)], number of prescribed drugs per day [OR = 1.46, 95% CI (1.02-2.07)] and GFR < 60 mL/min [OR = 1.49, 95% CI (1.01-2.2)]. Conclusion This is the first standardised pharmaceutical assessment dedicated to the elderly carried out by community pharmacists in France. If implemented, it could help to find drug-related problems, identify frail elderly patients and ultimately decrease their exposure to iatrogenic medication errors.

Technology-induced errors associated with computerized provider order entry software for older patients.

Background The introduction of new technologies in the prescribing process has seen the emergence of new types of medication errors. Objective To determine the prevalence and consequences of technology-induced prescription errors associated with a computerized provider order entry (CPOE) system in hospitalized older patients. Setting Patients 65 years or older admitted to the Departments of Internal Medicine, General Surgery, and Vascular Surgery of a tertiary hospital. Method Prospective observational 6-month study. Technology-induced errors were classified according to various taxonomies. Interrater reliability was measured. Consequences were assessed by interviewing patients and healthcare providers and classified according to their severity. Main outcome measure Prevalence of technology-induced errors. Results A total of 117 patients were included and 107 technology-induced errors were recorded. The prevalence of these errors was 3.65%. Half of the errors were clinical errors (n = 54) and the majority of these were classified as wrong dose, wrong strength, or wrong formulation. Clinical errors were 9 times more likely to be more severe than procedural errors (14.8 vs 1.9%; OR 9.04, 95% CI 1.09-75.07). Most of the errors did not reach the patient. Almost all errors were related to human-machine interactions due to wrong (n = 61) or partial (n = 41) entries. Conclusion Technology-induced errors are common and intrinsic to the implementation of new technologies such as CPOE. The majority of errors appear to be related to human-machine interactions and are of low severity. Prospective trials should be conducted to analyse in detail the way these errors occur and to establish strategies to solve them and increase patient safety.

A Closer Look at the 2015 Beers Criteria.

The Beers Criteria identifies potentially inappropriate medications for patients who are 65 years of age and older. Initially published in 1991, the criteria have been updated multiple times, most recently in 2015. The Beers Criteria is a tool designed to alert health-care providers to the potential harms of specific medications so they may better tailor therapeutic regimens for their elderly patients. The expert panel of the 2015 update made changes to a number of previous recommendations and provided 2 new tables on select drug interactions and select medications requiring renal dose adjustments. The purpose of this review is to provide additional details and rationale behind selected noteworthy changes within the 2015 criteria. Specific information is provided on the changes in recommendations for the use of nitrofurantoin, antiarrhythmics, nonbenzodiazepine receptor agonist hypnotics, antipsychotics, and proton pump inhibitors in the elderly. Additional comparisons are made between the 2012 recommendations and newer recommendations made in the 2015 update, along with rationale for the change. This review will allow practitioners to apply the 2015 Beers Criteria and integrate their clinical judgment when evaluating and selecting drug therapy for elderly patients.

Prevalence and risk factors for medication reconciliation errors during hospital admission in elderly patients.

Background Care transitions are risk points for medication discrepancies, especially in the elderly. Objective This study was undertaken to assess prevalence and describe medication reconciliation errors during admission in elderly patients and to analyze associated risk factors. We also evaluate the effect of these errors on the length of hospital stay. Setting General surgery, orthopedics, internal medicines and infectious diseases departments of a 1070-bed Spanish teaching hospital. Method This is a prospective observational study. Patients >65 years and taking ≥5 medications were randomly selected from those admitted to hospital. The pharmacist obtained the best possible medication history based on medical records, medical notes from patients' previous admissions to hospital, "brown bag" review, community care prescriptions, and comprehensive patient interviews. It was compared to current inpatient prescription to detect unintentional discrepancies (discrepancy with no apparent clinical explanation), which were reported to the physician. When the physician accepted the discrepancy by changing the medication order, it was recorded as a medication reconciliation error and classified by type of error. Several variables were analyzed as possible risk/protective factors. Main outcome measure Is prevalence of medication reconciliation errors at admission. Results Reconciliation was performed on 206 patients. Medication reconciliation errors occurred in 49.5 % (102/206) of patients. 1996 medications were recorded, and 359 had unintentional discrepancies (56.0 % (201/359) medication reconciliation errors). The most common was omission (65.1 %). Identified risk factors were as follows: physician experience, number of pre-admission prescribed medications, and previous surgeries. Computerized order entry system was a protective factor. Conclusion Medication reconciliation errors occur in almost half of the elderly patients at admission, especially omissions. Risk factors were a larger number of previous medications, less physician years of experience, and more previous surgeries. Having a computerized order entry system in the hospital protected against some errors.

Medication dispensing errors in Palestinian community pharmacy practice: a formal consensus using the Delphi technique.

Background Medication dispensing errors (MDEs) are frequent in community pharmacy practice. A definition of MDEs and scenarios representing MDE situations in Palestinian community pharmacy practice were not previously approached using formal consensus techniques. Objective This study was conducted to achieve consensus on a definition of MDEs and a wide range of scenarios that should or should not be considered as MDEs in Palestinian community pharmacy practice by a panel of community pharmacists. Setting Community pharmacy practice in Palestine. Method This was a descriptive study using the Delphi technique. A panel of fifty community pharmacists was recruited from different geographical locations of the West Bank of Palestine. A three round Delphi technique was followed to achieve consensus on a proposed definition of MDEs and 83 different scenarios representing potential MDEs using a nine-point scale. Main outcome measure Agreement or disagreement of a panel of community pharmacists on a proposed definition of MDEs and a series of scenarios representing potential MDEs. Results In the first Delphi round, views of key contact community pharmacists on MDEs were explored and situations representing potential MDEs were collected. In the second Delphi round, consensus was achieved to accept the proposed definition and to include 49 (59 %) of the 83 proposed scenarios as MDEs. In the third Delphi round, consensus was achieved to include further 13 (15.7 %) scenarios as MDEs, exclude 9 (10.8 %) scenarios and the rest of 12 (14.5 %) scenarios were considered equivocal based on the opinions of the panelists. Conclusion Consensus on a definition of MDEs and scenarios representing MDE situations in Palestinian community pharmacy practice was achieved using a formal consensus technique. The use of consensual definitions and scenarios representing MDE situations in community pharmacy practice might minimize methodological variations and their significant effects on the number and rate of MDEs reported in different studies.

A decade of Australian methotrexate dosing errors.

OBJECTIVE: Accidental daily dosing of methotrexate can result in life-threatening toxicity. We investigated methotrexate dosing errors reported to the National Coronial Information System (NCIS), the Therapeutic Goods Administration Database of Adverse Event Notifications (TGA DAEN) and Australian Poisons Information Centres (PICs). DESIGN AND SETTING: A retrospective review of coronial cases in the NCIS (2000-2014), and of reports to the TGA DAEN (2004-2014) and Australian PICs (2004-2015). Cases were included if dosing errors were accidental, with evidence of daily dosing on at least 3 consecutive days. MAIN OUTCOME MEASURES: Events per year, dose, consecutive days of methotrexate administration, reasons for the error, clinical features. RESULTS: Twenty-two deaths linked with methotrexate were identified in the NCIS, including seven cases in which erroneous daily dosing was documented. Methotrexate medication error was listed in ten cases in the DAEN, including two deaths. Australian PIC databases contained 92 cases, with a worrying increase seen during 2014-2015. Reasons for the errors included patient misunderstanding and incorrect packaging of dosette packs by pharmacists. The recorded clinical effects of daily dosage were consistent with those previously reported for methotrexate toxicity. CONCLUSION: Dosing errors with methotrexate can be lethal and continue to occur despite a number of safety initiatives in the past decade. Further strategies to reduce these preventable harms need to be implemented and evaluated. Recent suggestions include further changes in packet size, mandatory weekly dosing labelling on packaging, improving education, and including alerts in prescribing and dispensing software.

Medicines management.

Medication errors are the second most reported incident type in the NHS. Other concerns around medicines management include poor medicines security, theft and poor administration practice.

Reducing medication errors at admission: 3 cycles to implement, improve and sustain medication reconciliation.

BACKGROUND: In France, medication errors are the third leading cause of serious adverse events. Many studies have shown the positive impact of medication reconciliation (MR) on reducing medication errors at admission but this practice is still rarely implemented in French hospitals. OBJECTIVE: Implement and sustain a MR process at admission in two surgery units. The quality improvement approach used to meet this objective is described. SETTING: The gastrointestinal surgery and orthopedic surgery departments of a 407 inpatient bed French teaching hospital. METHODS: A step by step collaborative approach based on plan-do-study-act (PDSA) cycles. Three cycles were successively performed with regular feedback during multidisciplinary meetings. MAIN OUTCOME MEASURE: mean unintended medication discrepancies (UMDs) per patients at admission. RESULTS: The three PDSA cycles and the monitoring phase allowed to implement, optimize and sustain a MR process in the two surgery units. Cycle 1, by showing a rate of 0.65 UMDs at admission (95 % CI 0.39-0.91), underlined the need for a MR process; cycle 2 showed how the close-collaboration between pharmacy and surgery units could help to reduce mean UMDs per patients at admission (0.18; 95 % CI 0.09-0.27) (p < 0.001); finally, cycle 3 allowed the optimization of the MR process by reducing the delays of the best possible medication history availability. CONCLUSIONS: This work highlights how a collaborative quality-improvement approach based on PDSA cycles can meet the challenge of implementing MR to improve medication management at admission.

Epidermal necrolysis: 60 years of errors and advances.

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare conditions characterized by extensive epidermal detachment and mucositis. Both are associated with a high mortality rate and significant long-term morbidity. Since the initial report introducing the term TEN in 1956, diagnosis of the condition has been fraught with difficulties that continue to exist today. The terms 'erythema multiforme major' (EMM) and SJS, and their relationship to TEN have also been confusing to clinicians. It is now recognized that EMM is a different entity from SJS and TEN in terms of demographics, causality and severity. SJS and TEN represent a continuum of disease, and differ only by the extent of epidermal detachment and therefore severity. The term 'epidermal necrolysis' (EN) is used in this article to describe the spectrum of disease that includes SJS and TEN. Important advances in understanding the pathomechanism and treatment of EN have been made over the years. These include the recognition of human leucocyte antigen (HLA) associations (e.g. HLA-B*1502 with carbamazepine-induced TEN) and understanding of the pathogenic roles of drug-specific cytotoxic T cells and granulysin. It was previously believed that widespread keratinocyte death in EN is predominantly mediated by soluble Fas-ligand and that intravenous immunoglobulin therapy is useful in blocking this mechanism with resultant survival benefits. Further studies have since proven these theories to be incorrect. This short review describes the key advances in the terminology, classification, causality and treatment of EN, and identifies future priorities and challenges in the understanding and management of this condition.

Are older Western Australians exposed to potentially inappropriate medications according to the Beers Criteria? A 13-year prevalence study.

AIM: To examine time trends and factors associated with exposure to potentially inappropriate medications (PIMs) by the Beers Criteria. METHODS: PIM consumption days accumulated from the pharmaceutical claims of 251 305 Western Australians aged ≥65 years (1993-2005) and person follow-up times produced counts/rates. Logistic/Poisson regression generated odds/rate ratios. RESULTS: A total of 187 616 participants (74.7%) took ≥1 PIM (1993-2005), the cohort consuming 109 415 PIM daily doses/1000 person-years. Annual exposure decreased from 45-47% to 40%, and annual consumption rate declined from 117 836 to 90 364 daily doses/1000 person-years. Temazepam had the highest exposures (>17 000 daily doses/1000 person-years). Number of medications taken (OR 35.03; 95% CI 34.37-35.71 for ≥10 vs. 0-2 drugs), annual drug intake (2.08; 2.04-2.12 for highest vs. lowest quartile), and high-level residential aged care (1.96; 1.91-2.01) were most predictive of PIM exposure. CONCLUSIONS: PIM exposure remains high in older Western Australians. Our findings identify patients most at risk and medications to consider on Australia-specific PIM lists.

Can a redesign of emergency pharmacist roles improve medication management? A prospective study in three Australian hospitals.

BACKGROUND: Emergency departments (EDs) face increasing service demands and the imposition of treatment targets which has led to continual process redesign and changes in staff skill mix and functions. OBJECTIVE: To identify extended ED pharmacist roles that could improve medication management and to implement and evaluate one such role change. METHODS: A focus group of clinicians sought to redesign processes around ED medication management. Preparation of medication charts for patients admitted from ED was selected. Baseline data were obtained to define elements of existing medication charting processes. Suitably trained ED pharmacists' trialled the effectiveness of making therapeutic suggestions on a medication chart 'sticker' or by direct 'consultation' with medical staff. At the conclusion of the study focus groups at each site evaluated clinical staff perceptions of the change. RESULTS: Focus group participants thought that ED pharmacists could undertake extended roles in analgesia, nausea control, antibiotic cover, addiction management and preparation of medication charts for admitted patients. In the pre-intervention audit (n = 140), 74% required at least one intervention by the ward pharmacists to address medication discrepancies. Ward pharmacists detected 292 medication discrepancies (median 1, IQR 0-3). In the 'sticker' intervention the ED pharmacist made 84 therapeutic suggestions of which 66 (78.6%) were accepted by medical staff. In the 'consultation' intervention 230 therapeutic suggestions were made of which 219 (95.2%) were accepted. The qualitative evaluation found that pharmacist-prepared medication charts within the processes established were deemed safe, timely, accurate, complete and legible. CONCLUSION: Support exists for ED pharmacists to expand their medication-related roles. ED pharmacists can safely prepare medication charts in a timely fashion and their therapeutic suggestions within a 'consultative' framework are more beneficial than written advice. However, issues relating to resourcing, hours of service, service focus, statutory restrictions and training support for extended roles require resolution.

Errores de medicación en la Unidad de Cuidados Intensivos / Medication errors in the Unit Intensive Care

The safety and quality care are two attributes of the health care that are closely related. The critically ill patients are vulnerable to medical errors, and may experience preventable adverse events, often associated with drugs. The errors in the medication use process may occur at any stage, it is ordering, transcription, dispensing, preparation or administration. Medication errors (ME) can occur in one third of patients hospitalized in an ICU and have the potential to cause permanent damage to patients and longer hospital stay, with the resulting emotional and financial cost associated. Although technology can reduce the likelihood for adverse drug events, the optimal methods for implementation, integration, and evaluation in clinical practice remain unclear. In this paper we present some strategies and interventions to reduce the incidence of ME and optimize the safety and quality of care of critically ill patients (AU)

Erros de prescrição de medicamentos em um hospital brasileiro / Drug prescription errors in a Brazilian hospital

OBJETIVO: Identificar a prevalência de erros clinicamente significativos em prescrição de hospital universitário brasileiro, comparando sua ocorrência em 2003 e 2007. MÉTODOS: Análise das prescrições quanto às variáveis/grupo de variáveis como legibilidade, cumprimento de procedimentos legais e institucionais e análise de erros de prescrição. RESULTADOS: Quando calculadas as taxas de prevalência dos erros de prescrição clinicamente significativos, evidenciou-se uma redução estatisticamente significante [ano 2003 (29,25 por cento), ano 2007 (24,20 por cento); (z = 2,99; p = 0,03)], sendo refletido sobre a taxa de segurança [ano 2003 (70,75 por cento), ano 2007 (75,80 por cento); (z = 3,30; p = 0,0001]. CONCLUSÃO: Apesar de significativo, o aumento na taxa de segurança foi reflexo da redução quantitativa dos erros, não sendo observada diferença na gravidade dos mesmos entre os períodos. Nossos resultados sugerem que as medidas institucionais adotadas foram capazes de reduzir o número de erros, mas foram inefetivas na redução da gravidade dos mesmos.

OBJECTIVE: To identify the prevalence of clinically significant prescription errors in a Brazilian university hospital compared with their occurrence in 2003 and 2007. METHODS: Variables and group of variables, such as readability, compliance with legal and institutional procedures of prescription, and prescription errors analysis were analyzed. RESULTS: When the prevalence rates of clinically significant prescription errors were calculated, a statistically significant decrease was shown [year of 2003 (29.25 percent), year of 2007 (24.20 percent); (z = 2.99; p = 0.03)], reflecting on the safety rate [year of 2003 (70.75 percent), year of 2007 (75.80 percent); (z = 3.30; p =0.0001)]. CONCLUSION: Despite significant, the increased safety rate reflected the quantitative reduction of errors, with no observed difference in severity between the studied periods. Our results suggest the institutional steps taken could reduce the number of errors, but they were ineffective in reducing the severity of the errors.
