Efecto del farmacéutico clínico en las reconsultas a los 30 días posalta del servicio de urgencias: ensayo clínico controlado / Effect of a clinical pharmacist on 30-day revisits following discharge from an emergency department: a randomized controlled clinical trial

Objetivos. Determinar el efecto de la inclusión del farmacéutico clínico en el servicio de urgencias (SU) en las reconsultas durante 30 días posalta y la satisfacción de los pacientes. Métodos. Ensayo clínico controlado, aleatorizado, paralelo y pragmático, realizado en el SU de un hospital universitario. Los pacientes reclutados fueron asignados aleatoriamente al grupo control (GC) que recibió la atención habitual o al grupo intervenido (GI) que recibió además la atención de un farmacéutico clínico, el cual se integró al equipo clínico para optimizar la selección, evaluación y educación farmacoterapéutica en el SU y al alta. El desenlace primario fue reconsultas no programadas 30 días posaltarelacionadas con la atención inicial al SU. Las diferencias entre grupos se analizaron por curvas de supervivencia de Kaplan-Meier y prueba de log-rank. La asociación entre intervención y tiempo al evento fue analizada mediante regresión multivariada de riesgos proporcionales de Cox y se expresó como hazard ratio ajustada (HRa). Resultados. Un total de 1.001 pacientes ingresaron al estudio (GI=500 y GC=501). Ambos grupos eran similares, predominaron las mujeres (61,5%), edad 51 años (RIC: 33-65). La intervención redujo significativamente las reconsultas a cualquier centro durante 30 días posalta comparado con GC [25 (6,3%) vs 66 (16,7%); HRa: 0,29 (IC 95%: 0,17-0,50)] y para el mismo centro [15 (3,0%) vs 32 (6,5%); HRa: 0,46 (IC 95%: 0,24-0,87)]. La satisfacción del usuario fue mayor en el GI que GC (87,2% vs 83,2%; p<0,05). Conclusiones. La inclusión del farmacéutico clínico en un SU reduce sustancialmente las reconsultas durante 30 días posalta y mejora la satisfacción de los usuarios. (AU)

Objectives. To evaluate a clinical pharmacist’s inclusion in emergency department (ED) care in terms of the effect on on 30-day revisits after discharge from the ED and patient satisfaction. Methods. Randomized, controlled parallel-group pragmatic trial in a university hospital ED. Recruited patients were randomly assigned to a control group for standard care only or an intervention group to receive standard care plus the attention of a clinical pharmacist integrated into the care team to optimize the selection and evaluation of medications and provide pharmacotherapeutic education on the patient’s discharge. The primary outcome was unplanned revisits within 30 days after discharge because of the same complaint that led to the initial ED visit. Between-group differences were analyzed with Kaplan-Meier survival curves and log-rank tests. The association between the intervention and time to the outcome event was explored with multivariate Cox proportional hazard regression analysis. Results. A total of 1001 patients were enrolled (intervention, 500; control, 501). Patients in both groups were similar. A majority were women (61.5%), and the median age (interquartile range) was 51 years (33-65 years). The pharmacist’s intervention significantly reduced the number of 30-day revisits to any ED: 25 (6.3%) revisited vs 66 (16.7%) in the control group. The adjusted hazard ratio (aHR) was 0.29 (95% CI, 0.17-0.50). Fifteen patients (3.0%) from the intervention group revisited the same ED vs 32 (6.5%) from the control group (aHR, 0.46 [95% CI, 0.24-0.87]). More patients expressed satisfaction in the intervention group (87.2%) than in the control group ( 83.2%) (P<.05). Conclusions. Including a clinical pharmacist in ED care substantially reduces the number of 30-day revisits and increases patient satisfaction. (AU)

[Consumption of psychotropic medications in primary healthcare in Ribeirão Preto, São Paulo State, Brazil]. / Descrição do consumo de psicofármacos na atenção primária à saúde de Ribeirão Preto, São Paulo, Brasil.

The consumption of psychotropic drugs is considered a public health problem, due to the potential for addiction and the occurrence of adverse events. In this context, the current study aimed to characterize the consumption of psychotropic medications dispensed in primary healthcare units in Ribeirão Preto, São Paulo State, Brazil. This ecological study consulted the Hygia database from 2008 to 2012. The following variables were extracted: psychotropic drugs dispensed, amount dispensed per year, and patients' sex and age bracket. For each psychotropic drug, we calculated the defined daily dose per 1,000 inhabitants/day (DDD/1,000PD), defined daily dose per 1,000 inhabitants/day considering 75% of the population (DDD75%/1,000PD) who withdrew medicines through the Brazilian Unified National Health System (SUS), and the prescribed daily dose (PDD). The study compared the population growth rate to the growth in the medicines' consumption. A total of 1,577,241 patients were identified who withdrew medications during the study period, of whom 287,373 (18.2%) used at least one drug subject to special control. There was an increase in the total consumption of psychotropic drugs (DDD/1,000PD), but comparison to the population growth rate showed that only sertraline (p = 0.021), risperidone (p = 0.034), and clonazepam (p = 0.043) presented higher growth rates. The PDD for seven drugs were higher than the World Health Organization (WHO) DDD. Identifying discrepancies between DDD and PDD can be useful as a strategy for screening patients eligible for pharmaceutical care, since they can contribute to the prevention of morbidity and mortality related to medications.

Conduziu-se um estudo ecológico, com consulta à base de dados Hygia de 2008 a 2012. Foram extraídas as variáveis: psicofármaco dispensado, quantidade dispensada no ano, sexo e faixa etária dos pacientes. Para cada psicofármaco foi calculada a dose diária definida por 1.000 habitantes/dia (DDD/1.000PD), a dose diária definida por 1.000 habitantes/dia considerando-se 75% da população (DDD75%/1.000PD) que retiraram medicamento pelo Sistema Único de Saúde (SUS) e a dose diária prescrita (DDP). Comparou-se a taxa de crescimento populacional com a de crescimento do consumo dos medicamentos. Foram identificados 1.577.241 pacientes que retiraram medicamentos no período avaliado, dos quais 287.373 (18,2%) utilizaram pelo menos um sujeito a controle especial. Houve aumento do consumo total dos psicofármacos (DDD/1.000PD), porém, após a comparação com a taxa de crescimento populacional, apenas a da sertralina (p = 0,021), risperidona (p = 0,034) e do clonazepam (p = 0,043) foram superiores. As DDP de sete fármacos estavam maiores que a DDD da Organização Mundial da Saúde (OMS). As discrepâncias entre DDD e DDP podem ser úteis como estratégia para triar pacientes elegíveis ao cuidado farmacêutico, pois podem contribuir na prevenção de morbimortalidade relacionada ao uso de medicamentos.

Incident adverse drug reactions and their effect on the length of hospital stay in older inpatients.

Background Acutely ill older persons are more likely to suffer adverse drug reactions, increasing morbidity, and mortality. The incident adverse drug reactions and their consequences on the length of hospital stay (LOS) in older persons have been little explored. Objective To determine the incident adverse drug reactions in acutely ill older inpatients and their effect on the LOS. Setting Internal medicine service in a Chilean teaching hospital. Method A prospective cohort study was conducted in patients aged ≥ 60 years admitted into the internal medicine service of the Hospital from University of Chile. Characteristics, severity, and causality of adverse drug reactions were assessed. Effect of incident adverse drug reactions on the LOS was determined using multiple Cox regression. A secondary analysis was conducted in patients aged ≥ 65 years. Main outcome measure Incident adverse drug reactions (new events occurring in hospital) and their effect on the LOS in older inpatients. Results A total of 229 acutely ill older persons ≥ 60 years were followed-up. Fifty-six of them suffered 77 adverse drug reactions (incident rate 24.5%; 95% CI: 19.0, 30.5), 70.1% type A. Adverse drug reactions were severe in 5.4% of cases. Causality assessment indicated the majority were probable (57.1%) and 3.9% certain. Cardiovascular agents were the therapeutic class more frequently involved. The most frequent adverse drug reaction was hypotension (19.5%). Patients with adverse drug reactions had a significantly prolonged LOS than those without adverse drug reactions (12.4 ± 11.0 versus 7.3 ± 6.4 days; p < 0.0001) (adjusted Hazard Ratio 0.63; 95% CI: 0.46, 0.87; p < 0.01), respectively. The incidence rate of adverse drug reactions in patients ≥ 65 years was 25.1% (95% CI: 19.0; 32.1), and their occurrence was significantly associated with a prolonged LOS (p < 0.05). Conclusion One in four acutely ill older persons hospitalized in the internal medicine service suffered at least one incident adverse drug reaction, which prolonged the LOS by 5 days. There is a potential to optimize the use of hospital beds and medication safety by preventing adverse drug reactions in geriatric patients.

Prescripción de opioides al alta de un servicio de urgencia / Prescription of opioids at the moment of discharge from an emergency department

Background There is a worrisome increase in opioid prescription worldwide. Their use and overuse may cause adverse outcomes. Aim To determine incidence and characteristics of opioid prescription at discharge at an emergency department (ED). Material and Methods A prospective observational study in a random sample of adult patients attended at an ED of a teaching hospital. We reviewed medical records prescriptions for each patient to collect information about drugs prescribed, reason and medical indication of use (doses and duration). Results A total of 1,001 patients aged 50 ± 20 years (61% women) were studied. Seven percent of patients received an opioid prescription at discharge from the ED, mainly to treat renal and back pain. The dose, duration of treatments or both were incompletely described in 54% of prescriptions. The dose of tramadol in drops was incomplete in 96% of prescriptions. Conclusions Seven percent of patients discharged from an ED received an opioid prescription, mainly to treat non-oncological acute pain. The lack of information detected in the prescriptions affected quality, safety and effectiveness of the treatment, especially when pharmaceutical formulations were drops.

Trends in Prevalence and Determinants of Potentially Inappropriate Prescribing in the United States: 2007 to 2012.

OBJECTIVES: To estimate the prevalence and determinants of the use of potentially inappropriate medications (PIMs) in older U.S. adults using the 2012 Beers criteria. DESIGN: Retrospective cohort study in a random national sample of Medicare beneficiaries. SETTING: Fee-for-service Medicare beneficiaries from 2007 to 2012. PARTICIPANTS: U.S. population aged 65 and older with Parts A, B, and D enrollment in at least 1 month during a calendar year (N = 38,250 individuals; 1,308,116 observations). MEASUREMENTS: The 2012 Beers criteria were used to estimate the prevalence of the use of PIMs in each calendar month and over a 12-month period using data on diagnoses or conditions present in the previous 12 months. Generalized estimating equations were used to account for the dependence of multiple monthly observations of a single person when estimating 95% confidence intervals (CIs), and logistic regression was used to identify independent determinants of PIM use. RESULTS: The point prevalence of the use of PIMs decreased from 37.6% (95% CI = 37.0-38.1) in 2007 to 34.2% (95% CI = 33.6-34.7) in 2012, with a statistically significant 2% (95% CI = 1-3%) decline per year assuming a linear trend. The 1-year period prevalence declined from 64.9% in 2007 to 56.6% in 2012. The strongest predictor of PIM use was the number of drugs dispensed. Individuals aged 70 and older and those seen by a geriatrician were less likely to receive a PIM. CONCLUSION: From 2007 to 2012, the prevalence of PIM use in older U.S. adults decreased according to the 2012 Beers criteria, although it remains high, still affecting one-third each month and more than half over 12 months. The number of dispensed prescriptions could be used to target future interventions.

[Monitoring medication errors in an internal medicine service]. / Errores de medicación en el Servicio de Medicina de un hospital de alta complejidad.

BACKGROUND: Patients admitted to internal medicine services receive multiple drugs and thus are at risk of medication errors. AIM: To determine the frequency of medication errors (ME) among patients admitted to an internal medicine service of a high complexity hospital. MATERIAL AND METHODS: A prospective observational study conducted in 225 patients admitted to an internal medicine service. Each stage of drug utilization system (prescription, transcription, dispensing, preparation and administration) was directly observed by trained pharmacists not related to hospital staff during three months. ME were described and categorized according to the National Coordinating Council for Medication Error Reporting and Prevention. In each stage of medication use, the frequency of ME and their characteristics were determined. RESULTS: A total of 454 drugs were prescribed to the studied patients. In 138 (30,4%) indications, at least one ME occurred, involving 67 (29,8%) patients. Twenty four percent of detected ME occurred during administration, mainly due to wrong time schedules. Anticoagulants were the therapeutic group with the highest occurrence of ME. CONCLUSIONS: At least one ME occurred in approximately one third of patients studied, especially during the administration stage. These errors could affect the medication safety and avoid achieving therapeutic goals. Strategies to improve the quality and safe use of medications can be implemented using this information.

Effects of the implementation of a preventive interventions program on the reduction of medication errors in critically ill adult patients.

PURPOSE: Medication errors (MEs) are a major factor limiting the effectiveness and safety of pharmacological therapies in critically ill patients. The purpose was to determine if a preventive interventions program (PIP) is associated with a significant reduction on prevalence of patients with MEs in intensive care unit (ICU). METHODS: A prospective before-after study was conducted in a random sample of adult patients in a medical-surgical ICU. Between 2 observational phases, a PIP (bundle of interventions to reduce MEs) was implemented by a multidisciplinary team. Direct observation was used to detect MEs at baseline and postintervention. Each medication process, that is, prescription, transcription, dispensing, preparation, and administration, was compared with what the prescriber ordered; if there was a difference, the error was described and categorized. Medication errors were defined according to the National Coordinating Council for Medication Error Reporting and Prevention. RESULTS: A total of 410 medications for 278 patients were evaluated. A 31.7% decrease on the prevalence of patients with MEs (41.9%-28.6%; P < .05) was seen. Main variations occurred in anti-infectives for systemic use and prescription and administration stage. CONCLUSIONS: The implementation of PIP by a multidisciplinary team resulted in a significant reduction on the prevalence of patients with ME at an adult ICU.

Impacto del cuidado multidisciplinario en los desenlaces clínicos de los pacientes críticos / Impact of multidisciplinary teams on clinical outcomes of critically ill patients

La seguridad de los pacientes críticos en la Unidad de Cuidados Intensivos (UCI), ha sido progresivamente reconocida como un componente esencial de la práctica de la medicina intensiva moderna. La creación y promoción de equipos multidisciplinarios liderados por un intensivista ha demostrado mejorar la seguridad de la atención de salud. La incorporación de un farmacéutico con entrenamiento especializado a la UCI, ha generado un impacto positivo en los desenlaces clínicos y económicos. El fomento de la cultura de la seguridad en la UCI y el rediseño de los procesos defectuosos pueden mejorar significativamente la seguridad y calidad de la atención de los pacientes críticos.

The safety of critically ill patients in Intensive Care Unit (ICU) has been increasingly recognized as an essential component of the practice of modern intensive care. The creation and promotion of intensivist-led multidisciplinary teams has shown to improve the safety of health care. The addition in the ICU of a pharmacist with specialized training has generated a positive impact on clinical and economic outcomes. The promotion of safety culture in the ICU and the redesign of faulty processes can significantly improve the safety and quality of care of critically ill patients.

[Factors associated with non-compliance with antidepressant treatment in Santiago, Chile]. / Factores asociados al incumplimiento de los tratamientos con antidepresivos en Santiago, Chile.

OBJECTIVE: To identify factors associated with non-compliance to antidepressant's (AD) treatment in Santiago, Chile. METHODS: A cross-sectional study was carried out in a household randomized and representative sample of 1000 individuals aged 15 years and older. Treatment adherence was studied in AD consumers using logistic regression to estimate factors associated with non-compliance in doses or time of treatment. RESULTS: Antidepressant non-compliance was 52.8% and their main associated factor was income. Gender and educational level were also associated with AD non-compliance. CONCLUSIONS: Antidepressant non-compliance was associated with income and sociodemographic characteristics in Chilean patients. Therefore, health strategies to improve AD compliance should consider inequities in access to medications and characteristics of the AD consumers.

[Consumption of antidepressants in Chile from 1992 to 2004]. / Consumo de antidepresivos en Chile entre 1992 y 2004.

BACKGROUND: Data from the Ministry of Health show that in Chile in 2004, 17% of the population had some form of depression, and mood disorders are the tenth cause of disability-adjusted life years (DALY) loss. AIM: To determine consumption of antidepressants (ADs) in Chile from 1992 to 2004. MATERIAL AND METHODS: National sales data were obtained from the company IMS Health Chile and converted into defined daily doses (DDDs) per 1,000 inhabitants per day. Available ADs were classified in four pharmacological groups (i.e., serotonin-norepinephrine reuptake inhibitors, SNRLs; selective-serotonin reuptake inhibitors, SSRLs; tricyclic antidepressants, TCAs; and others). Total economic burden of ADs utilization and cost per DDDs were also calculated. Trends over time were analyzed using Pearson-R2. RESULTS: Total ADs consumption in Chile measured by DDDs per 1,000 inhabitants per day (DHD) increased linearly (y =0.901x + 1.9129; R2 =0.9296; p <0.001) from 2.5 in 1992 to 11.7 in 2004 (total growth of 470.2%). SSRLs were the drug class with higher consumption, and fluoxetine the most commonly consumed antidepressant. SSRLs were the drugs that dominated the market representing 79% of the total drug consumption throughout the years. Total economic burden of ADs in Chile (total cost of DDDs consumed) increased from US$65.4 million in 2001 to US$74.6 million in 2004 (14% increase). Average cost per DDD of all AD increased linearly, however not significantly from US$ 0.94 in 2001 to US$ 1.04 in 2004 (y =0.0362x + 0.8784; R2 =0.7382; p =0,262). CONCLUSIONS: DDDs per 1,000 inhabitants per day increased linearly over 470% from 1992-2004. SSRLs were the most commonly consumed drugs in Chile. Future research should evaluate the cost-effectiveness of antidepressants in Chile, comparing the results with drug utilization, and determining if unnecessary expenditures have been paid out.
