Enhancing Operational Efficiency and Service Delivery through a Robotic Dispensing System: A Case Study from a Retail Pharmacy in Brazil.

Drug dispensing in retail pharmacies typically involves several manual tasks that often lead to inefficiencies and errors. This is the first published quality improvement study in Latin America, specifically in Brazil, investigating the operational impacts of implementing a robotic dispensing system in a retail pharmacy. Through observational techniques, we measured the time required for the following pharmacy workflows before and after implementing the robotic dispensing system: customer service, receiving stock, stocking inventory, separation, invoicing, and packaging of online orders for delivery. Time savings were observed across all workflows within the pharmacy, notably in receiving stock and online order separation, which experienced 70% and 75% reductions in total time, respectively. Furthermore, customer service, stocking, invoicing, and packaging of online orders, also saw total time reductions from 36% to 53% after implementation of the robotic dispensing system. This study demonstrates an improvement in the pharmacy's operational efficiency post-implementation of the robotic dispensing system. These findings highlight the potential for such automated systems to streamline pharmacy operations, improve staff time efficiency, and enhance service delivery.

Systematic evidence review of rates and burden of harm of intravenous admixture drug preparation errors in healthcare settings.

OBJECTIVE: To examine published evidence on intravenous admixture preparation errors (IAPEs) in healthcare settings. METHODS: Searches were conducted in three electronic databases (January 2005 to April 2017). Publications reporting rates of IAPEs and error types were reviewed and categorised into the following groups: component errors, dose/calculation errors, aseptic technique errors and composite errors. The methodological rigour of each study was assessed using the Hawker method. RESULTS: Of the 34 articles that met inclusion criteria, 28 reported the site of IAPEs: central pharmacies (n=8), nursing wards (n=14), both settings (n=4) and other sites (n=3). Using the Hawker criteria, 14% of the articles were of good quality, 74% were of fair quality and 12% were of poor quality. Error types and reported rates varied substantially, including wrong drug (~0% to 4.7%), wrong diluent solution (0% to 49.0%), wrong label (0% to 99.0%), wrong dose (0% to 32.6%), wrong concentration (0.3% to 88.6%), wrong diluent volume (0.06% to 49.0%) and inadequate aseptic technique (0% to 92.7%)%). Four studies directly compared incidence by preparation site and/or method, finding error incidence to be lower for doses prepared within a central pharmacy versus the nursing ward and lower for automated preparation versus manual preparation. Although eight studies (24%) reported ≥1 errors with the potential to cause patient harm, no study directly linked IAPE occurrences to specific adverse patient outcomes. CONCLUSIONS: The available data suggest a need to continue to optimise the intravenous preparation process, focus on improving preparation workflow, design and implement preventive strategies, train staff on optimal admixture protocols and implement standardisation. Future research should focus on the development of consistent error subtype definitions, standardised reporting methodology and reliable, reproducible methods to track and link risk factors with the burden of harm associated with these errors.

Primary Intravenous Set Consumption Across 3 Branded Infusion Pumps.

This retrospective study of 6426 hip replacement, coronary artery bypass graft, and colectomy surgeries across 23 US hospitals found that intravenous (IV) set designs that can be interchanged for use both in gravity-fed and automated pump delivery systems are replaced less frequently than IV sets designed for use primarily by one delivery method. Semistructured interviews with nurses highlighted the impact of set design on nursing workflow when moving between gravity-fed and pump-based administration. Use of interchangeable, single-design IV sets across gravity and automated infusions minimizes disruptions to closed systems, may reduce nurses being distracted from patients' clinical needs when replacing sets, and may yield supply cost savings.

Cost-effectiveness of Chloride-liberal versus Chloriderestrictive Intravenous Fluids among Patients Hospitalized in the United States.

Background: Patients developing acute kidney injury (AKI) during critical illness or major surgery are at risk for renal sequelae such as costly and invasive acute renal replacement therapy (RRT) and chronic dialysis (CD). Rates of renal injury may be reduced with use of chloride-restrictive intravenous (IV) resuscitation fluids instead of chloride-liberal fluids. Objectives: To compare the cost-effectiveness of chloride-restrictive versus chloride-liberal crystalloid fluids used during fluid resuscitation or for the maintenance of hydration among patients hospitalized in the US for critical illnesses or major surgery. Methods: Clinical outcomes and costs for a simulated patient cohort (starting age 60 years) receiving either chloride-restrictive or chloride-liberal crystalloids were estimated using a decision tree for the first 90-day period after IV fluid initiation followed by a Markov model over the remainder of the cohort lifespan. Outcomes modeled in the decision tree were AKI development, recovery from AKI, progression to acute RRT, progression to CD, and death. Health states included in the Markov model were dialysis free without prior AKI, dialysis-free following AKI, CD, and death. Estimates of clinical parameters were taken from a recent meta-analysis, other published studies, and the US Renal Data System. Direct healthcare costs (in 2015 USD) were included for IV fluids, RRT, and CD. US-normalized health-state utilities were used to calculate quality-adjusted life years (QALYs). Results: In the cohort of 100 patients, AKI was predicted to develop in the first 90 days in 36 patients receiving chloride-liberal crystalloids versus 22 receiving chloride-restrictive crystalloids. Higher costs of chloride-restrictive crystalloids were offset by savings from avoided renal adverse events. Chloride-liberal crystalloids were dominant over chloride-restrictive crystalloids, gaining 93.5 life-years and 81.4 QALYs while saving $298 576 over the cohort lifespan. One-way sensitivity analyses indicated results were most sensitive to the relative risk for AKI development and relatively insensitive to fluid cost. In probabilistic sensitivity analyses with 1000 iterations, chloride-restrictive crystalloids were dominant in 94.7% of iterations, with incremental cost-effectiveness ratios below $50 000/QALY in 99.6%. Conclusions: This analysis predicts improved patient survival and fewer renal complications with chloriderestrictive IV fluids, yielding net savings versus chloride-liberal fluids. Results require confirmation in adequately powered head-to-head randomized trials.

El sistema cerrado en la prevención de las infecciones del torrente sanguíneo / The closed infusion system in the prevention of bloodstream infections

Los pacientes hospitalizados están en continuo riesgo de infecciones del torrente sanguíneo (ITS), especialmente en las unidades de cuidado intensivo (UCI). Las ITS constituyen 14% de las infecciones nosocomiales (IN) y representan casi un tercio de las muertes asociadas con IN. Es así que se han establecido pautas de prevención y protocolos de manejo para reducir el impacto de las ITS asociadas a catéteres (CR). Entre ellas están las diferencias entre contenedores de infusión intravenosa (IV). Los de infusión abierto necesitan la introducción de aire para su vaciamiento. Los de infusión cerrado son contenedores colapsables que no requieren aire para su vaciamiento. En conclusión, en la era de la seguridad del paciente se hace necesario que los sistemas de salud propendan por hacer los cambios en la tecnología que redundan en una mejor atención y que muchas veces son costo/efectivas (Acta Med Colomb 2011; 36: 105-107).

Hospitalized patients are at continued risk of bloodstream infections (BSI), especially in intensive care units (ICU). BSI constitute 14% of nosocomial infections (HAI) and represent almost a third of deaths associated with HAI. It is well established that prevention guidelines and management protocols reduce the impact of BSI associated with catheters (CR). Among them are the differences between containers intravenous (IV). The open infusion required the introduction of air for emptying. The closed infusion are collapsible containers that do not require air for emptying. In conclusion, in the era of patient safety it is necessary to propitiate health systems to make the changes in technology that result in improved care and often are cost-effective (Acta Med Colomb 2011; 36: 105-107).

A multicentre, prospective study to evaluate costs of septic patients in Brazilian intensive care units.

BACKGROUND: Sepsis has a high prevalence within intensive care units, with elevated rates of morbidity and mortality, and high costs. Data on sepsis costs are scarce in the literature, and in developing countries such as Brazil these data are largely unavailable. OBJECTIVES: To assess the standard direct costs of sepsis management in Brazilian intensive care units (ICUs) and to disclose factors that could affect those costs. METHODS: This multicentre observational cohort study was conducted in adult septic patients admitted to 21 mixed ICUs of private and public hospitals in Brazil from 1 October 2003 to 30 March 2004. Complete data for all patients admitted to the ICUs were obtained until their discharge or death. We collected only direct healthcare-related costs, defined as all costs related to the ICU stay. Enrolled patients were assessed daily in terms of cost-related expenditures such as hospital fees, operating room fees, gas therapy, physiotherapy, blood components transfusion, medications, renal replacement therapy, laboratory analysis and imaging. Standard unit costs (year 2006 values) were based on the Brazilian Medical Association (AMB) price index for medical procedures and the BRASINDICE price index for medications, solutions and hospital consumables. Medical resource utilization was also assessed daily using the Therapeutic Intervention Scoring System (TISS-28). Indirect costs were not included. RESULTS: With a mean (standard deviation [SD]) age of 61.1 +/- 19.2 years, 524 septic patients from 21 centres were included in this study. The overall hospital mortality rate was 43.8%, the mean Acute Physiology And Chronic Health Evaluation II (APACHE II) score was 22.3 +/- 5.4, and the mean Sequential Organ Failure Assessment (SOFA) score at ICU admission was 7.5 +/- 3.9. The median total cost of sepsis was $US 9632 (interquartile range [IQR] 4583-18 387; 95% CI 8657, 10 672) per patient, while the median daily ICU cost per patient was $US 934 (IQR 735-1170; 95% CI 897, 963). The median daily ICU cost per patient was significantly higher in non-survivors than in survivors, i.e. $US 1094 (IQR 888-1341; 95% CI 1058, 1157) and $US 826 (IQR 668-982; 95% CI 786, 854), respectively (p < 0.001). For patients admitted to public and private hospitals, we found a median SOFA score at ICU admission of 7.5 and 7.1, respectively (p = 0.02), and the mortality rate was 49.1% and 36.7%, respectively (p = 0.006). Patients admitted to public and private hospitals had a similar length of stay of 10 (IQR 5-19) days versus 9 (IQR 4-16) days (p = 0.091), and the median total direct costs for public ($US 9773; IQR 4643-19 221; 95% CI 8503, 10 818) versus private ($US 9490; IQR 4305-17 034; 95% CI 7610, 11 292) hospitals did not differ significantly (p = 0.37). CONCLUSIONS: The present study provides the first economic analysis of direct costs of sepsis in Brazilian ICUs and reveals that the cost of sepsis treatment is high. Despite similar ICU management, there was a significant difference regarding patient outcome between private and public hospitals. Finally, the median daily costs of non-survivor patients were higher than survivors during ICU stay.

Multiple brain abscesses due to Penicillium spp infection.

We present a case of central nervous system (CNS) infection by a member of the Penicillium genera in a HIV-negative man in Brazil. The patient was admitted complaining of loss of visual fields and speech disturbances. CT scan revealed multiple brain abscesses. Stereotactic biopsies revealed fungal infection and amphotericin B treatment begun with initial improvement. The patient died few days later as a consequence of massive gastrointestinal bleeding due to ruptured esophageal varices. The necropsy and final microbiologic analyses disclosed infection by Penicillium sp. There are thousands of fungal species of the Penicillium genera. Systemic penicilliosis is caused by the P. marneffei and was formerly a rare disease, but now is one of the most common opportunistic infection of AIDS patients in Southeast Asia. The clinical presentation usually involves the respiratory system and the skin, besides general symptoms like fever and weight loss. Penicillium spp infection caused by species other than P. marneffei normally cause only superficial or allergic disease but rare cases of invasive disease do occur. We report the fourth case of Penicillium spp CNS infection.

Multiple brain abscesses due to Penicillium spp infection

Apresentamos um caso de infecção do sistema nervoso central (SNC) por Penicillium spp em paciente do sexo masculino, HIV-negativo no Brasil. O paciente apresentou-se ao Serviço de Urgência do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo queixando-se de alteração visual e dificuldade na fala. Exames de neuroimagem mostraram lesões múltiplas, compatíveis com abscessos. A biópsia esterotáxica revelou infecção fúngica, iniciando-se o tratamento com anfotericina B com sucesso inicial. O paciente morreu poucos dias depois, vítima de uma hemorragia digestiva maciça devido a varizes de esôfago. A necropsia e a análise microbiológica final da biópsia cerebral revelaram infecção por Penicillium spp. Exixtem centenas de espécies de fungos do gênero Penicillium. A peniciliose sistêmica é causada pelo P. marneffei e costumava ser uma doença rara, mas atualmente é uma das infecções oportunistas mais comuns em associação com AIDS no Sudeste Asiático. Infecção pelo Penicillium spp de espécie diferente do P. marneffei normalmente causa apenas doenças superficiais ou alérgicas mas doenças invasivas também ocorrem raramente. Nós relatamos o quarto caso de infecção do SNC por Penicillium spp.
