A retrospective case-control study to evaluate the use of beta-lactam desensitization in the management of penicillin-allergic patients: a potential strategy for Antimicrobial Stewardship Programs.

Introduction: Penicillin allergy labels (PAL) are common in the hospital setting and are associated with worse clinical outcomes. Desensitization can be a useful strategy for allergic patients when alternative options are suboptimal or not available. The aim was to compare clinical outcomes of patients with PAL managed with antibiotic desensitization vs. those who received alternative non-beta-lactam antibiotic treatments. Methods: A retrospective 3:1 case-control study was performed between 2015-2022. Cases were adult PAL patients with infection who required antibiotic desensitization; controls were PAL patients with infection managed with an alternative antibiotic treatment. Cases and controls were adjusted for age, sex, infection source, and critical or non-critical medical services. Results: Fifty-six patients were included: 14 in the desensitization group, 42 in the control group. Compared to the control group, desensitized PAL patients had more comorbidities, with a higher Charlson index (7.4 vs. 5; p = 0.00) and more infections caused by multidrug-resistant (MDR) pathogens (57.1% vs. 28.6%; p = 0.05). Thirty-day mortality was 14.3% in the desensitized group, 28.6% in the control group (p = 0.24). Clinical cure occurred in 71.4% cases and 54.8% controls (p = 0.22). Four control patients selected for MDR strains after alternative treatment; selection of MDR strains did not occur in desensitized patients. Five controls had antibiotic-related adverse events, including Clostridioides difficile or nephrotoxicity. No antibiotic-related adverse events were found in the study group. In multivariate analysis, no differences between groups were observed for main variables. Conclusion: Desensitization was not associated with worse clinical outcomes, despite more severe patients in this group. Our study suggests that antibiotic desensitization may be a useful Antimicrobial Stewardship tool for the management of selected PAL patients.

Telehealth model versus in-person standard care for persons with type 1 diabetes treated with multiple daily injections: an open-label randomized controlled trial.

Objective: Increasing evidence indicates that the telehealth (TH) model is noninferior to the in-person approach regarding metabolic control in type 1 diabetes (T1D) and offers advantages such as a decrease in travel time and increased accessibility for shorter/frequent visits. The primary aim of this study was to compare the change in glycated hemoglobin (HbA1c) at 6 months in T1D care in a rural area between TH and in-person visits. Research design and methods: Randomized controlled, open-label, parallel-arm study among adults with T1D. Participants were submitted to in-person visits at baseline and at months 3 and 6 (conventional group) or teleconsultation in months 1 to 4 plus 2 in-person visits (baseline and 6 months) (TH group). Mixed effects models estimated differences in HbA1c changes. Results: Fifty-five participants were included (29 conventional/26 TH). No significant differences in HbA1c between groups were found. Significant improvement in time in range (5.40, 95% confidence interval (CI): 0.43-10.38; p < 0.05) and in time above range (-6.34, 95% CI: -12.13- -0.55;p < 0.05) in the TH group and an improvement in the Diabetes Quality of Life questionnaire (EsDQoL) score (-7.65, 95% CI: -14.67 - -0.63; p < 0.05) were observed. In TH, the costs for the participants were lower. Conclusions: The TH model is comparable to in-person visits regarding HbA1c levels at the 6-month follow-up, with significant improvement in some glucose metrics and health-related quality of life. Further studies are necessary to evaluate a more efficient timing of the TH visits.

Comparative Analysis of Complicated Urinary Tract Infections Caused by Extensively Drug-Resistant Pseudomonas aeruginosa and Extended-Spectrum ß-Lactamase-Producing Klebsiella pneumoniae.

The objective was to compare clinical characteristics, outcomes, and economic differences in complicated urinary tract infections (cUTI) caused by extensively drug-resistant Pseudomonas aeruginosa (XDR P. aeruginosa) and extended-spectrum beta-lactamase-producing Klebsiella pneumoniae (ESBL-K. pneumoniae). A retrospective study was conducted at a tertiary care hospital. Patients with XDR P. aeruginosa and ESBL-K. pneumoniae cUTIs were compared. The primary outcome was clinical failure at day 7 and at the end of treatment (EOT). Secondary outcomes: 30- and 90-day mortality, microbiological eradication, and economic cost. Two-hundred and one episodes were included, of which 24.8% were bloodstream infections. Patients with XDR P. aeruginosa cUTI more frequently received inappropriate empirical therapy (p < 0.001). Nephrotoxicity due to antibiotics was only observed in the XDR P. aeruginosa group (26.7%). ESBL-K. pneumoniae cUTI was associated with worse eradication rates, higher recurrence, and higher infection-related readmission. In multivariate analysis, XDR P. aeruginosa was independently associated with clinical failure on day 7 of treatment (OR 4.34, 95% CI 1.71−11.04) but not at EOT, or with mortality. Regarding hospital resource consumption, no significant differences were observed between groups. XDR P. aeruginosa cUTI was associated with worse early clinical cures and more antibiotic side effects than ESBL-K. pneumoniae infections. However, no differences in mortality or in hospitalization costs were observed.

¿La integración de la gestión de servicios sanitarios mejora la coordinación clínica? Experiencia en Cataluña / Does the integration of health services management improve clinical coordination? Experience in Catalonia

Objetivo: Analizar la experiencia y la percepción de coordinación clínica entre niveles asistenciales y los factores relacionados, organizativos y de interacción entre profesionales, según el tipo de integración de la gestión de los servicios de salud del área en Cataluña. Método: Estudio transversal basado en una encuesta on-line mediante autoadministración del cuestionario COORDENA-CAT (octubre-diciembre 2017). Población de estudio: médicos/as de atención primaria y especializada de agudos y media y larga estancia del sistema sanitario catalán. Muestra: 3308 médicos/as. Variables de resultado: experiencia y percepción de coordinación clínica, conocimiento y uso de mecanismos de coordinación y factores relacionados. Variables explicativas: área según tipo de gestión (integrada, semiintegrada, no integrada), sociodemográficas, laborales y de actitud. Análisis descriptivos por tipo de área y multivariados mediante regresión de Poisson robusta. Resultados: Se observaron mejores resultados de experiencia y percepción de coordinación clínica en áreas integradas que en semiintegradas, en especial en la transferencia de información y el seguimiento adecuado entre niveles. En cambio, no se encontraron diferencias entre áreas integradas y no integradas en la experiencia, aunque sí en la percepción de coordinación y algunos factores. Algunos problemas identificados son comunes a todas las áreas, como la accesibilidad entre niveles. Conclusiones: Las pocas diferencias entre áreas integradas y no integradas parecen indicar que la integración de la gestión puede facilitar la coordinación clínica, pero no es condición suficiente. Las diferencias con áreas semiintegradas parecen indicar la necesidad de promover la cooperación entre todos los proveedores de un territorio, con objetivos y mecanismos de coordinación comunes, para evitar desigualdades en la calidad asistencial.

Objective: To analyze the experience and perception of clinical coordination across care levels and doctor's organizational and interactional related factors, according to the type of management integration of the healthcare services of the area, in Catalonia. Method: Cross-sectional study based on an online survey by self-administration of the questionnaire COORDENA-CAT. Data collection: October-December 2017. Study population: primary and secondary care (acute and long-term care) doctors of the public Catalan health system. Sample: 3308 doctors. Outcome variables: experience and perception of clinical coordination, knowledge and use of coordination mechanisms and organizational and interactional factors; explanatory variables: area according to type of management (integrated, semi-integrated, non-integrated), socio-demographic, employment characteristics and attitude toward work. Descriptive analysis by type of area and multivariate analysis by robust Poisson regression. Results: Better clinical coordination was observed in integrated areas compared to those semi-integrated, mainly in relation to information transfer, adequate follow-up and perception of coordination in the area. No differences were found between integrated and non-integrated areas in the clinical coordination experience, although there were differences in perception and some related factors. There are common problems across areas, such as accessibility to secondary care. Conclusions: Few differences were found between integrated and non-integrated areas, revealing that management integration may facilitate clinical coordination but is not enough. Differences with semi-integrated areas indicate the need to promote cooperation formulas between all the providers of the territory, with common objectives and coordination mechanisms, in order to avoid inequalities in quality of care.

Cost-effectiveness Analysis of Peripherally Inserted Central Catheters Versus Central Venous Catheters for in-Hospital Parenteral Nutrition.

OBJECTIVE: Our objective was to evaluate the cost-effectiveness of the use of peripherally inserted central venous catheters (PICCs) by a vascular access team (VAT) versus central venous catheters (CVCs) for in-hospital total parenteral nutrition (TPN). METHODS: The study used a cost-effectiveness analysis based on observational data retrospectively obtained from electronic medical records from 2018 to 2019 in a teaching hospital. We included all interventional procedures requiring PICCs or CVCs with the indication of TPN. We recorded the costs of insertion, maintenance, removal, and complications. The main outcome measure was the incidence rate of catheter-associated bacteremia per 1000 catheter days. Cost-effectiveness analysis was performed from the hospital perspective within the context of the publicly funded Spanish health system. Confidence intervals for costs and effectiveness differences were calculated using bootstrap methods. RESULTS: We analyzed 233 CVCs and 292 PICCs from patients receiving TPN. Average duration was longer for PICC (13 versus 9.4 days, P < 0.001). The main reason for complications in both groups was suspected infection (9.77% CVC versus 5.18% PICC). Complication rates due to bacteremia were 2.44% for CVC and 1.15% for PICC. The difference in the incidence of bacteremia per 1000 catheter days was 1.29 (95% confidence interval, -0.89 to 3.90). Overall, costs were lower for PICCs than for CVCs: the difference in mean overall costs was -€559.9 (95% confidence interval, -€919.9 to -€225.4). Uncertainty analysis showed 86.37% of results with lower costs and higher effectiveness for PICC versus CVC. CONCLUSIONS: Placement of PICC by VAT compared with CVC for TPN reduces costs and may decrease the rate of bacteremia.

Impact of Non-Persistence on Healthcare Resource Utilization and Costs in Patients With Immune-Mediated Rheumatic Diseases Initiating Subcutaneous TNF-Alpha Inhibitors: A Before-and-After Study.

Rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis are chronic progressive immune-mediated rheumatic diseases (IMRD) that can cause a progressive disability and joint deformation and thus can impact in healthcare resource utilization (HCRU) and costs. The main outcome of the study was to assess the effect of non-persistence to treatment with subcutaneous tumor necrosis factor-alpha inhibitors (SC-TNFis) on HCRU costs in naïve patients with IMRD who started treatment with adalimumab, etanercept, golimumab or certolizumab pegol during 12 months after initiation of treatment. The impact of persistence and non-persistence of SC-TNFis on HCRU costs was compared between 12 months before and 12 months after initiating SC-TNFis. Persistence was defined as the duration of time from initiation to discontinuation of therapy. The study was conducted in an acute care teaching hospital in Barcelona, Spain. Data for the period between 2015 and 2018 were extracted from the hospital cost management control database. HCRU costs comprised outpatient care, outpatient specialized rheumatology care, in-patient care, emergency care, laboratory testing and other non-biological therapies. The study population included 110 naïve SC-TNFis patients, divided into the cohorts of persistent (n = 85) and non-persistent (n = 25) patients. Fifty-six percent of patients were women, with a mean (standard deviation) age of 47.6 (14.8) years. Baseline clinical features and HCRU costs over the 12 months before the index prescription were similar in the two study groups. Before-and-after differences in mean (standard deviation) HCRU costs were significantly higher in the non-persistence group as compared to the persistence group for outpatient rheumatology care (€110.90 [234.56] vs. €20.80 [129.59], p = 0.023), laboratory testing (-€193.99 [195.88] vs. -€241.3 [217.88], p = 0.025), other non-biological drugs (€3849.03 [4046.14] vs. -€10.90 [157.42], p < 0.001) and total costs (€3268.90 [4821.55] vs. -€334.67 (905.44), p < 0.001). Treatment persistence with SC-TNFis may be associated with HCRU cost savings in naïve IMRD patients. Prescribing SC-TNFis with the best long-term persistence is beneficial.

Understanding How to Improve the Use of Clinical Coordination Mechanisms between Primary and Secondary Care Doctors: Clues from Catalonia.

Clinical coordination between primary (PC) and secondary care (SC) is a challenge for health systems, and clinical coordination mechanisms (CCM) play an important role in the interface between care levels. It is therefore essential to understand the elements that may hinder their use. This study aims to analyze the level of use of CCM, the difficulties and factors associated with their use, and suggestions for improving clinical coordination. A cross-sectional online survey-based study using the questionnaire COORDENA-CAT was conducted with 3308 PC and SC doctors in the Catalan national health system. Descriptive bivariate analysis and logistic regression models were used. Shared Electronic Medical Records were the most frequently used CCM, especially by PC doctors, and the one that presented most difficulties in use, mostly related to technical problems. Some factors positively associated with frequent use of various CCM were: working full-time in integrated areas, or with local hospitals. Interactional and organizational factors contributed to a greater extent among SC doctors. Suggestions for improving clinical coordination were similar between care levels and related mainly to the improvement of CCM. In an era where management tools are shifting towards technology-based CCM, this study can help to design strategies to improve their effectiveness.

Doctors' opinions on clinical coordination between primary and secondary care in the Catalan healthcare system / Opinión de los médicos sobre coordinación entre atención primaria y especializada en el sistema de salud catalán

Objective: To analyse doctors' opinions on clinical coordination between primary and secondary care in different healthcare networks and on the factors influencing it. Methods: A qualitative descriptive-interpretative study was conducted, based on semi-structured interviews. A two-stage theoretical sample was designed: 1) healthcare networks with different management models; 2) primary care and secondary care doctors in each network. Final sample size (n = 50) was reached by saturation. A thematic content analysis was conducted. Results: In all networks doctors perceived that primary and secondary care given to patients was coordinated in terms of information transfer, consistency and accessibility to SC following a referral. However, some problems emerged, related to difficulties in acceding non-urgent secondary care changes in prescriptions and the inadequacy of some referrals across care levels. Doctors identified the following factors: 1) organizational influencing factors: coordination is facilitated by mechanisms that facilitate information transfer, communication, rapid access and physical proximity that fosters positive attitudes towards collaboration; coordination is hindered by the insufficient time to use mechanisms, unshared incentives in prescription and, in two networks, the change in the organizational model; 2) professional factors: clinical skills and attitudes towards coordination. Conclusions: Although doctors perceive that primary and secondary care is coordinated, they also highlighted problems. Identified factors offer valuable insights on where to direct organizational efforts to improve coordination

Objetivo: Analizar la opinión de los médicos sobre la coordinación entre la atención primaria (AP) y la atención especializada (AE) en diferentes redes de servicios de salud, e identificar los factores relacionados. Método: Estudio cualitativo descriptivo-interpretativo basado en entrevistas semiestructuradas. Se diseñó una muestra teórica en dos etapas: 1) redes de servicios de salud con diferentes modelos de gestión; 2) en cada red, médicos de AP y AE. El tamaño muestral se alcanzó por saturación (n = 50). Se realizó un análisis temático de contenido. Resultados: En las tres redes, los médicos expresaron que la atención está coordinada en términos de intercambio de información, consistencia y accesibilidad de AE tras derivación urgente. Sin embargo, emergieron problemas relacionados con el acceso no urgente y cambios en prescripciones, y en dos redes la inadecuación clínica de las derivaciones entre ambos niveles. Se identificaron los siguientes factores relacionados: 1) organizativos: facilitan la coordinación, la existencia de mecanismos de transferencia de información, de comunicación y de acceso rápido, y la proximidad física que promueve actitudes positivas a la colaboración; la obstaculizan el tiempo insuficiente para el uso de mecanismos, incentivos no compartidos en la prescripción y, en dos redes, un cambio del modelo organizativo; 2) relacionados con los profesionales: habilidades clínicas y actitudes frente a la coordinación. Conclusiones: Aunque los médicos perciben que la atención entre niveles está coordinada, también señalan problemas. Los factores identificados muestran hacia dónde dirigir los esfuerzos organizativos para su mejora

Incremental cost of nosocomial bacteremia according to the focus of infection and antibiotic sensitivity of the causative microorganism in a university hospital.

To estimate the incremental cost of nosocomial bacteremia according to the causative focus and classified by the antibiotic sensitivity of the microorganism.Patients admitted to Hospital del Mar in Barcelona from 2005 to 2012 were included. We analyzed the total hospital costs of patients with nosocomial bacteremia caused by microorganisms with a high prevalence and, often, with multidrug-resistance. A control group was defined by selecting patients without bacteremia in the same diagnosis-related group.Our hospital has a cost accounting system (full-costing) that uses activity-based criteria to estimate per-patient costs. A logistic regression was fitted to estimate the probability of developing bacteremia (propensity score) and was used for propensity-score matching adjustment. This propensity score was included in an econometric model to adjust the incremental cost of patients with bacteremia with differentiation of the causative focus and antibiotic sensitivity.The mean incremental cost was estimated at &OV0556;15,526. The lowest incremental cost corresponded to bacteremia caused by multidrug-sensitive urinary infection (&OV0556;6786) and the highest to primary or unknown sources of bacteremia caused by multidrug-resistant microorganisms (&OV0556;29,186).This is one of the first analyses to include all episodes of bacteremia produced during hospital stays in a single study. The study included accurate information about the focus and antibiotic sensitivity of the causative organism and actual hospital costs. It provides information that could be useful to improve, establish, and prioritize prevention strategies for nosocomial infections.

Cost and detection rate of glaucoma screening with imaging devices in a primary care center.

PURPOSE: To analyze the cost and detection rate of a screening program for detecting glaucoma with imaging devices. MATERIALS AND METHODS: In this cross-sectional study, a glaucoma screening program was applied in a population-based sample randomly selected from a population of 23,527. Screening targeted the population at risk of glaucoma. Examinations included optic disk tomography (Heidelberg retina tomograph [HRT]), nerve fiber analysis, and tonometry. Subjects who met at least 2 of 3 endpoints (HRT outside normal limits, nerve fiber index ≥30, or tonometry ≥21 mmHg) were referred for glaucoma consultation. The currently established ("conventional") detection method was evaluated by recording data from primary care and ophthalmic consultations in the same population. The direct costs of screening and conventional detection were calculated by adding the unit costs generated during the diagnostic process. The detection rate of new glaucoma cases was assessed. RESULTS: The screening program evaluated 414 subjects; 32 cases were referred for glaucoma consultation, 7 had glaucoma, and 10 had probable glaucoma. The current detection method assessed 677 glaucoma suspects in the population, of whom 29 were diagnosed with glaucoma or probable glaucoma. Glaucoma screening and the conventional detection method had detection rates of 4.1% and 3.1%, respectively, and the cost per case detected was 1,410 and 1,435€, respectively. The cost of screening 1 million inhabitants would be 5.1 million euros and would allow the detection of 4,715 new cases. CONCLUSION: The proposed screening method directed at population at risk allows a detection rate of 4.1% and a cost of 1,410 per case detected.

Impacto económico de las bacteriemias nosocomiales. Comparación de tres metodologías de cálculo / Economic impact of nosocomial bacteraemia. A comparison of three calculation methods

INTRODUCCIÓN: El coste incremental que comportan las bacteriemias nosocomiales (BN) se utiliza como medida del impacto de estas infecciones. Los métodos tradicionales de cálculo de coste sobrestiman este incremento al no contemplar variables confusoras. El objetivo de este trabajo es comparar 3 metodologías de cálculo del coste incremental de la BN para corregir los sesgos presentes en análisis previos. MÉTODOS: Se compararon los pacientes que presentaron algún episodio de BN entre 2005 y 2007, con los pacientes con la misma patología sin BN. Los microorganismos causantes se agruparon según la tinción Gram y según si la bacteriemia era monomicrobiana o polimicrobiana, o producida por un hongo. Se compararon 3 métodos de cálculo: 1) estratificación por patología; 2) ajuste econométrico multivariante mediante un modelo lineal generalizado (MLG), y 3) un propensity score matching (PSM) antes del análisis multivariante para controlar los sesgos. RESULTADOS: Se analizaron 640 hospitalizaciones con BN y 28.459 sin BN; el coste medio observado fue de 24.515 € y 4.851,6 €, respectivamente. En la estratificación por patología, el coste incremental medio estimado fue de 14.735 €, el grupo de microorganismos que ocasionó menor coste incremental fue el de grampositivos, con 10.051€. En el MLG el coste incremental medio estimado fue de 20.922 €, mientras que utilizando PSM se estimó un coste incremental medio de 11.916 €. En las 3 estimaciones hay diferencias importantes según el grupo de microorganismos. CONCLUSIONES: Utilizar metodologías más elaboradas mejora el ajuste en este tipo de estudios e incrementa el valor de los resultados obtenidos

INTRODUCTION: The excess cost associated with nosocomial bacteraemia (NB) is used as a measurement of the impact of these infections. However, some authors have suggested that traditional methods overestimate the incremental cost due to the presence of various types of bias. The aim of this study was to compare three assessment methods of NB incremental cost to correct biases in previous analyses. METHODS: Patients who experienced an episode of NB between 2005 and 2007 were compared with patients grouped within the same All Patient Refined-Diagnosis-Related Group (APR-DRG) without NB. The causative organisms were grouped according to the Gram stain, and whether bacteraemia was caused by a single or multiple microorganisms, or by a fungus. Three assessment methods are compared: stratification by disease; econometric multivariate adjustment using a generalised linear model (GLM); and propensity score matching (PSM) was performed to control for biases in the econometric model. RESULTS: The analysis included 640 admissions with NB and 28,459 without NB. The observed mean cost was €24,515 for admissions with NB and €4,851.6 for controls (without NB). Mean incremental cost was estimated at €14,735 in stratified analysis. Gram positive microorganism had the lowest mean incremental cost, €10,051. In the GLM, mean incremental cost was estimated as €20,922, and adjusting with PSM, the mean incremental cost was €11,916. The three estimates showed important differences between groups of microorganisms. CONCLUSIONS: Using enhanced methodologies improves the adjustment in this type of study and increases the value of the results

Economic evaluation of treatments for patients with localized prostate cancer in Europe: a systematic review.

BACKGROUND: Our objective was to assess the efficiency of treatments in patients with localized prostate cancer, by synthesizing available evidence from European economic evaluations through systematic review. METHODS: Articles published 2000-2015 were searched in MEDLINE, EMBASE and NHS EED (Prospero protocol CRD42015022063). Two authors independently selected studies for inclusion and extracted the data. A third reviewer resolved discrepancies. We included European economic evaluations or cost comparison studies, of any modality of surgery or radiotherapy treatments, regardless the comparator/s. Drummond's Checklist was used for quality assessment. RESULTS: After reviewing 8,789 titles, 13 European eligible studies were included: eight cost-utility, two cost-effectiveness, one cost-minimization, and two cost-comparison analyses. Of them, five compared interventions with expectant management, four contrasted robotic with non robotic-assisted surgery, three assessed new modalities of radiotherapy, and three compared radical prostatectomy with brachytherapy. All but two studies scored ≥8 in the quality checklist. Considering scenario and comparator, three interventions were qualified as dominant strategies (active surveillance, robotic-assisted surgery and IMRT), and six were cost-effective (radical prostatectomy, robotic-assisted surgery, IMRT, proton therapy, brachytherapy, and 3DCRT). However, QALY gains in most of them were small. For interventions considered as dominant strategies, QALY gain was 0.013 for active surveillance over radical prostatectomy; and 0.007 for robotic-assisted over non-robotic techniques. The highest QALY gains were 0.57-0.86 for radical prostatectomy vs watchful waiting, and 0.72 for brachytherapy vs conventional radiotherapy. CONCLUSIONS: Currently, relevant treatment alternatives for localized prostate cancer are scarcely evaluated in Europe. Very limited available evidence supports the cost-effectiveness of radical prostatectomy over watchful waiting, brachytherapy over radical prostatectomy, and new treatment modalities over traditional procedures. Relevant disparities were detected among studies, mainly based on effectiveness. These apparently contradictory results may be reflecting the difficulty of interpreting small differences between treatments regarding QALY gains.
