ObjectiveTo analyse the factors leading to greater satisfaction among patients attending the outpatient hospital pharmacy (OPh).MethodsA 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.ResultsA 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.ConclusionsOur 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.

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.

The aim of the study was to assess the direct costs for the Spanish Health System of patients with chronic inflammatory arthropathies treated with biological therapies in daily clinical practice and to establish possible factors associated with lower costs. MethodsA descriptive, observational and retrospective study was conducted. Patients with rheumatoid arthritis, ankylosing spondylitis and psoriatic arthritis who started a biological therapy between 1 January 2009 and 31 December 2016 were included. Variables related to socioeconomic status, disease and biological therapy were included. The annual cost of biological treatment and other direct medical costs were calculated for each disease. The analysis of costs was based on the National Health Service perspective. The time horizon comprised the 8-year long study period. ResultsA total of 422 biological therapy lines were analysed. The annual biological therapy cost per patient was €12,494±3,865 for rheumatoid arthritis, €11,248±2,763 for ankylosing spondylitis and €12,263±35,155 for psoriatic arthritis (p=0.008). The cost of biological therapies entailed about 80% of the total cost of these diseases. Hospital admission was a factor which contributed to an increasing cost in all these conditions. A longer duration of the biological therapy was associated with lower cost in all the diseases. ConclusionThe cost of ankylosing spondylitis is lower than that of rheumatoid arthritis and psoriatic arthritis. The biological therapy is the factor with the highest impact on the overall cost of these diseases. Preventing hospital admissions and a higher persistence to the biological therapy can contribute to lower costs for the system.

European Journal of Rheumatology (Eur J Rheumatol) is an international, open access peer reviewed journal committed to promoting the highest standards of scientific exchange and education. The journal is published quarterly on January, April, July and October. The aim of the European Journal of Rheumatology is to cover various aspects of rheumatology for its readers, encompassing the spectrum of diseases with arthritis, musculoskeletal conditions, autoinflammatory diseases, connective tissue disorders, osteoporosis, translational research, the latest therapies and treatment programs. European Journal of Rheumatology publishes original articles, invited reviews, case based reviews, letters to the editor and images in rheumatology. The publication language of the journal is English. Accepted manuscripts are copy-edited for grammar, punctuation, and format. Once the publication process of a manuscript is completed, it is published online on the journal's webpage as an aheadof-print publication before it is included in its scheduled issue.
