Design and validation of quality indicators for drug dispensing in a pediatric hospital.

OBJECTIVES: This article presents a methodological strategy to design and validate quality indicators for drug dispensing in a pediatric hospital. SETTING: The literature evaluation, design, and validation of indicators by experts were carried out from September 2017 to March 2018 in the pharmaceutical services of a pediatric hospital at the Autonomous University of the State of Hidalgo, Mexico. PRACTICE DESCRIPTION: The design and validation of quality indicators for dispensing allow the evaluation, planning, and follow-up of this activity. PRACTICE INNOVATION: The development of the indicators follows a holistic vision considering the relationship between the structure on which the pediatric dispensation is based, the involved processes, and the outcomes and provide a simple tool to improve the quality of the dispensing service. EVALUATION: A methodological investigation for the development of systems and health services in drug dispensing was performed. For the indicator's design, the Mexican standards for establishments dedicated to the sale and supply of drugs, the Good Dispensation Practices, and the Donabedian model were considered. The validation of such indicators was carried out using the Delphi method and the Torgerson mathematical model. RESULTS: Indicators of structure, process, and results were designed; of the 16 indicators designed, 15 reached the average score of greater than 3.5, and the percentage of experts who qualified each indicator in the highest categories was greater than 50%. CONCLUSION: The design of indicators guarantees the quality of the dispensing service and can be extrapolated to the pharmaceutical services of any pediatric hospital.

Feasibility and reliability of a quality indicator system for an ambulatory dispensing service.

Background: For a medication dispensing service to function with quality, continuous evaluation is required, which is why it is necessary to have reliable measurement tools that make it possible. Quality indicators can serve as tools for managing quality, as they are variables that directly or indirectly measure changes in a situation and help evaluate the progress made in addressing it. This article aims to determine the feasibility and reliability of a quality indicator system for a drug dispensing service for paediatric outpatients in two Mexican hospitals. Methods: A study of the development type of health systems and services at a microlevel was conducted from October 2020 to October 2021 in the pharmaceutical service of two Mexican hospitals. To determine the feasibility of the quality indicators, a retrospective evaluation was performed, which considered the indicators that could be calculated with the available information to be feasible. To determine reliability, an inter-observer agreement study (Kappa (κ)) was performed. Results: The feasibility analysis revealed that all five reference indicators related to the structure were feasible in both hospitals. In the Infantil of the Californias hospital, all six process indicators evaluated were feasible, whilst only one was found feasible in H+ Querétaro. As for outcome indicators, only one was feasible in the Infantil of the Californias hospital. The causes of non-feasibility in both hospitals were the non-documentation of the primary data related to the stages of the process and the lack of instruments to measure patient satisfaction. The reliability of the indicators showed little variability. Conclusion: Although not all indicators were feasible, solutions were proposed so that the 15 reference indicators could be used if an organization decided to do so. The reliability of the indicators was demonstrated, evidencing the importance of the data sheet as a tool to generate valid reliable measures.This article is part of the Hospital pharmacy, rational use of medicines and patient safety in Latin America Special Issue: https://www.drugsincontext.com/special_issues/hospital-pharmacy-rational-use-of-medicines-and-patient-safety-in-latin-america/.

Methodological - Theoretical approach to phenomenological studies on the experience of medication use: A systematic review.

BACKGROUND: The study of medication use should include pharmacological, family, and social dimensions to explain how the lived experiences, beliefs, and perceptions of everyone, and their social and cultural environment affects consumption, using for this purpose the qualitative approach. OBJECTIVE: To conduct a systematic review of the theoretical-methodological approaches to phenomenology to identify studies that allow an understanding of patients' experiences with the use of medications.a. METHODS: A systematic literature search was conducted following the PRISMA guidelines to identify studies that address phenomenological research on patients' experiences of medications used and to apply them in subsequent studies. A thematic analysis was performed using ATLAS.ti software to facilitate data management. RESULTS: Twenty-six articles were identified, most of them including adult patients diagnosed with chronic degenerative diseases. The semantic network obtained places Phenomenology at the center as the interpretative referential framework, with three theoretical approaches: descriptive, interpretative, and perceptual under the philosophies of Husserl, Heidegger, and Merleau-Ponty respectively; two techniques to collect data which are in-depth interview and focus groups; and to explore the life experiences of patients and understand the meaning in the context of their lives, thematic analysis, content analysis, and interpretative phenomenological analysis were identified. CONCLUSIONS: It was evidenced that Qualitative Research approaches, methodologies, and techniques are applicable to describe people's experiences towards the use of medications. Phenomenology constitutes a useful referential framework in qualitative research to explain the experiences and perceptions about the disease and the use of medicines.

Use of Biomedical Engineering for Rehabilitation of Patients with Disability Caused by Guillain-Barré Syndrome: a Systematic Review / Uso de la Ingeniería Biomédica para Rehabilitación de Pacientes con Discapacidad Causada por el Síndrome de Guillain-Barré: Una Revisión Sistemática

Abstract This systematic review aims to assess the extent to which biomedical engineering has been applied in the rehabilitation of patients suffering from Guillain-Barré Syndrome (GBS), given the scarcity of information on this topic. We conducted a thorough analysis of research articles, conference abstracts, and case reports published between 2000 and 2023, specifically from ScienceDirect, PubMed, IEEE Xplore, Springer, and Dimensions. 19 articles were extensively discussed, complemented by an additional 40 information sources providing supplementary information. Each paper underwent a meticulous review process by the four authors, where each separately examined the title and abstract of the papers and subsequently provided a thorough examination of the full text; when conflicts arose, a clear consensus was reached through discussion. The analysis of the articles revealed a notable improvement in upper and lower limb function of GBS patients that was facilitated by both custom-made and commercial devices. Likewise, a small handful of other devices have been used (e.g., to improve urinary retention issues). There is a clear opportunity for new research, innovation and applications.

Resumen Esta revisión sistemática tiene como objetivo evaluar hasta qué punto se ha aplicado la ingeniería biomédica en la rehabilitación de pacientes que padecen el Síndrome de Guillain-Barré (SGB), dada la escasez de información sobre este tema. Realizamos un análisis exhaustivo de artículos de investigación, resúmenes de conferencias e informes de casos publicados entre 2000 y 2023, específicamente de ScienceDirect, PubMed, IEEE Xplore, Springer y Dimensions. Se discutieron ampliamente 19 artículos, complementados con 40 fuentes de información adicionales. Cada artículo pasó por un meticuloso proceso de revisión por parte de los cuatro autores, donde cada uno examinó por separado el título y el resumen de los artículos y posteriormente proporcionó un examen exhaustivo del texto completo; cuando surgieron conflictos, se alcanzó un consenso mediante la discusión. El análisis de los artículos reveló una mejora notable en la función de las extremidades superiores e inferiores de los pacientes con SGB que fue facilitada por dispositivos tanto hechos a medida como comerciales. Asimismo, se han creado un pequeño puñado de otros dispositivos, (por ejemplo, para mejorar los problemas de retención urinaria). Existe una clara oportunidad para nueva investigación, innovación y aplicaciones.

Effect of dichloromethylene diphosphonate on liver regeneration following thioacetamide-induced necrosis in rats.

AIM: To study the effect of dichloromethylene diphosphonate (DMDP), a selective Kupffer cell toxicant in reference to liver damage and postnecrotic liver regeneration in rats induced by sublethal dose thioacetamide (TA). METHODS: Rats, intravenously (iv) pre-treated with a single dose of DMDP (10 mg/kg), were intraperitoneally (ip) injected with TA 6.6 mmol/kg (per 500 mg/kg body weight). Hepatocytes were isolated from rats at 0, 24, 48 and 72 h following TA intoxication and blood and liver samples were obtained. To evaluate the mechanisms involved in the postnecrotic regenerative state, DNA distribution and ploidy time course were assayed in isolated hepatocytes. Circulating cytokine tumor necrosis factor-alpha (TNF-α) was assayed in serum and determined by reverse transcriptase-polymerase chain reaction in liver extract. RESULTS: The effect of DMDP induced noticeable changes in postnecrotic regeneration, causing an increased percentage of hepatocytes in the cell cycle S phase. The increase at 24 h in S1 population in rats pretreated with DMDP + TA was significantly (P < 0.05) different compared with that of the TA group (18.07% vs 8.57%). Hepatocytes increased their proliferation as a result of these changes. Also, TNF-α expression and serum level were increased in rats pre-treated with DMDP. Thus, DMDP pre-treatment reduced TA-induced liver injury and accelerated postnecrotic liver regeneration. CONCLUSION: These results demonstrate that Kupffer cells are involved in TA-induced liver, as well as in postnecrotic proliferative liver states.
