Objective To analyse the factors leading to greater satisfaction among patients attending the outpatient hospital pharmacy (OPh). Methods A cross-sectional study was conducted of patients attending the OPh of a 1250-bed university hospital. A self-administered questionnaire for measuring outpatients' satisfaction was developed. Global satisfaction was measured on a scale of 1 to 10. Indices of perceived quality for accessibility, interpersonal professional–patient relationship and the convenience of the process were modelled through a principal component analysis using varimax rotation. The relationship between the principal components and overall satisfaction was evaluated using regression analysis. Results A questionnaire-based survey was conducted between May and June 2015. A total of 509 valid responses (86.9% response rate) were collected from the OPh. The overall satisfaction score was 7.81 (95% CI 7.59 to 8.04). The principal component analysis produced two components that explained 62.1% of the variance. The first component (CP1) contained questions related to the adequacy of the resources and services. The second component (CP2) contained questions about interpersonal professional–patient relationship. An additional unit in the CP2 was associated with a 3.23 increased risk of having higher satisfaction scores, while an increase of an additional unit in CP1 was associated with a 1.93 increased risk of having higher satisfaction scores. Conclusions Our study shows that the factor which predicts the satisfaction of patients who come to the OPh is the quality of care provided by pharmacists—in particular, information provided, resolution of doubts, personal attention and time devoted to the patient.

Background/Objectives: Non-small-cell lung cancer (NSCLC) accounts for approximately 85% of all lung cancer cases and is a leading cause of morbidity and mortality worldwide. Between 35% and 65% of NSCLC patients experience nutritional problems or malnutrition, which significantly affects their prognosis and quality of life. This study aims to describe the nutritional status and body composition of NSCLC patients treated with osimertinib, an oral tyrosine kinase inhibitor, while also assessing the prevalence of sarcopenia, presarcopenia, and dynapenia. Additionally, we explore the relationship between dose-limiting toxicities (DLTs) and nutritional status, as well as the impact of nutritional status on quality of life using the EQ-5D scale. Methods: A cross-sectional, observational study was conducted in 25 adult patients diagnosed with NSCLC treated with osimertinib under pharmacotherapeutic follow-up in the Pharmacy Consultations of a tertiary-level hospital. Anthropometric parameters, body composition (via bioimpedance analysis), and muscle functionality (via dynamometry) were assessed. Quality of life was evaluated using the EQ-5D scale. Results: The results showed that 36% of patients were malnourished, 4% had sarcopenia, 8% were presarcopenic, and 20% had dynapenia. Patients with DLTs exhibited significantly lower values of fat-free mass and the fat-free mass index, suggesting a relationship between low muscle mass and increased toxicities. Conclusions: These findings underscore the importance of early, individualized nutritional interventions in NSCLC patients treated with osimertinib to improve nutritional status and optimize oncological outcomes. Further research with larger cohorts and longitudinal designs is necessary to confirm these findings.

What is known and objective Initial treatment recommendations of COVID‐19 were based on the use of antimicrobial drugs and immunomodulators. Although information on drug interactions was available for other pathologies, there was little evidence in the treatment of COVID‐19. The objective of this study was to analyse the potential drug‐drug interactions (pDDIs) derived from the medication used in COVID‐19 patients in the first pandemic wave and to evaluate the real consequences of such interactions in clinical practice. Methods Cohort, retrospective and single‐centre study carried out in a third‐level hospital. Adult patients, admitted with suspected COVID‐19, that received at least one dose of hydroxychloroquine, lopinavir/ritonavir, interferon beta 1‐b or tocilizumab and with any pDDIs according to "Liverpool Drug Interaction Group" between March and May 2020 were included. The possible consequences of pDDIs at the QTc interval level or any other adverse event according to the patient's medical record were analysed. A descriptive analysis was carried out to assess possible factors that may affect the QTc interval prolongation. Results and discussion Two hundred and eighteen (62.3%) patients of a total of 350 patients admitted with COVID‐19 had at least one pDDI. There were 598 pDDIs. Thirty‐eight pDDIs (6.3%) were categorized as not recommended or contraindicated. The mean value difference between baseline and pDDI posterior ECG was 412.3 ms ± 25.8 ms vs. 426.3 ms ± 26.7 ms; p < 0.001. Seven patients (5.7%) had a clinically significant alteration of QTc. A total of 44 non‐cardiological events (7.3%) with a possible connection to a pDDI were detected. What is new and conclusion The number of pDDIs in patients admitted for COVID‐19 in the first pandemic wave was remarkably high. However, clinical consequences occurred in a low percentage of patients. Interactions involving medications that would be contraindicated for concomitant administration are rare. Knowledge of these pDDIs and their consequences could help to establish appropriate therapeutic strategies in patients with COVID‐19 or other diseases with these treatments.

(1) Background: parenteral nutrition (PN) solutions are an extremely complex mixture. It is composed of a multitude of chemical elements that can give rise to a large number of interactions that condition its stability and safety. The aim of this study was to evaluate the stability of PN solutions for preterm infants. (2) Methods: eight samples were prepared according to the protocol for prescribing PN in preterm infants. Samples PN1–PN7 had the normal progression of macronutrients and standard amounts of micronutrients for a 1 kg preterm infant. The PN8 sample had a high concentration of electrolytes, with the idea of forcing stability limits. Samples were stored both at room temperature and under refrigeration. Measurements of globule size, pH, density, and viscosity were performed in both storage protocols on different days after processing. (3) Results: the changes in the composition of the samples did not affect the evolution of the stability at the different measurement times and temperatures. Viscosity was affected by the compositional changes made in the PN samples, but no alterations due to time or temperature were observed. Density and pH remained stable, without significant changes due to time, storage temperature, or different composition. (4) Conclusion: all samples remained stable during the study period and did not undergo significant alterations due to compositional changes or different experimental conditions.

(1) Background: Parenteral nutrition (PN) is a technique used for the administration of nutrients to patients for whom traditional routes cannot be used. It is performed using solutions with extremely complex compositions, which can give rise to a large number of interactions. These interactions can impact their stability and put the patient’s life at risk. The aim of this study is to determine how changes in composition and storage protocol affect the stability of NP solutions. (2) Methods: Twenty-three samples were prepared according to routine clinical practice, with modifications to the concentration of some components. The samples were stored at room temperature (RT) and refrigerated (4 °C). Measurements of the droplet diameter, pH, density and viscosity were performed for both storage protocols on days 1, 3, 10 and 14. (3) Results: The samples with the lowest concentration of lipids (PN13-17) and proteins (PN18-22) showed a larger droplet diameter than the rest of the samples throughout the experiments. The USP limits were exceeded for some of the measurements of these sample groups. The pH density and viscosity remained relatively constant under the conditions studied. (4) Conclusions: The PN samples were considered stable and safe for administration under real-world conditions, but the samples with the lowest concentrations of lipids and proteins showed a tendency towards emulsion instability.
