New paradigms on antibiotic recommendations for community-acquired infections in Spain / Nuevos paradigmas en las recomendaciones antibióticas en las infecciones comunitarias en España

Over the last years, the susceptibility activity of the most common microorganisms causing community-acquired infections has significantly changed in Spain. Based on the susceptibility rates of Streptococcus pyogenes, Streptococcus pneumoniae, Haemophilus influenzae, Escherichia coli, and Klebsiella pneumoniae collected from outpatients aged 15 or older with symptoms of respiratory or urinary tract infections in several Microbiology Departments in Catalonia in 2021, penicillin V should be first choice for most respiratory tract infections, amoxicillin and clavulanate for chronic obstructive pulmonary disease exacerbations and a single dose of fosfomycin or a short-course nitrofurantoin should remain first-line treatments for uncomplicated urinary tract infections. Updated information on antimicrobial resistance for general practitioners is crucial for achieving appropriate empirical management of the most common infections by promoting more rational antibiotic use.(AU)

En los últimos años han cambiado significativamente los porcentajes de sensibilidad de los microorganismos más comunes que causan infecciones adquiridas en la comunidad en España. A partir de los porcentajes de sensibilidad de Streptococcus pyogenes, Streptococcus pneumoniae, Haemophilus influenzae, Escherichia coli y Klebsiella pneumoniae, recogidas de aislados de pacientes ambulatorios de 15 años o más, con síntomas de infecciones respiratorias o urinarias en servicios de microbiología de Cataluña en 2021, fenoximetilpenicilina debería ser la primera opción en la mayoría de los infecciones respiratorias, amoxicilina y ácido clavulánico en las exacerbaciones de la enfermedad pulmonar obstructiva crónica y la monodosis de fosfomicina o la pauta corta de nitrofurantoína como tratamiento de primera línea en las infecciones urinarias no complicadas. Es importante que los médicos de familia dispongan de información actualizada sobre la resistencia a los antimicrobianos para lograr un manejo empírico adecuado de las infecciones más frecuentes al promover un uso más racional de los antibióticos.(AU)

Fracture risk after deprescription of bisphosphonates: Application of real-world data in primary care / Riesgo de fractura después de la desprescripción de bifosfonatos: aplicación de real-world data en atención primaria

Purpose: To compare the effect of discontinuing bisphosphonate treatment on fracture risk in postmenopausal women at high versus low risk of fracture. Design: Retrospective, longitudinal and population-based cohort study. Setting: Barcelona City Primary Care. Catalan Health Institute. Participants: All women attended by primary care teams who in January 2014 had received bisphosphonate treatment for at least five years were included and followed for another five years. Intervention: Patients were classified according to their risk of new fractures, defined as those who had a history of osteoporotic fracture and/or who received treatment with an aromatase inhibitor, and the continuity or deprescription of the bisphosphonate treatment was analyzed over fiver year follow-up. Main measurements: The cumulative incidence of fractures and the incidence density were calculated and analyzed using logistic regression and Cox models. Results: We included 3680 women. There were no significant differences in fracture risk in high-risk women who discontinued versus continued bisphosphonate treatment (hazard ratio [HR] 1.17, 95% confidence interval [CI] 0.87–1.58 for total osteoporotic fractures). However, discontinuers at low risk had a lower incidence of fracture than continuers. This difference was significant for vertebral fractures (HR 0.64, 95% CI 0.47–0.88) and total fractures (HR 0.77, 95% CI 0.64–0.92). Conclusion: Our results suggest that deprescribing bisphosphonates in women who have already received five years of treatment does not increase fracture risk. In low-risk women, continuing this treatment might could even favor the appearance of new osteoporotic fractures.(AU)

Objetivo: Comparar el efecto de la desprescripción de bifosfonatos sobre el riesgo de fractura en mujeres posmenopáusicas con alto y bajo riesgo de fractura. Diseño: Estudio de cohortes retrospectivo, longitudinal y de base poblacional. Emplazamiento: Atención primaria Barcelona. Institut Català de la Salut. Participantes: Se incluyeron todas las mujeres atendidas por los equipos de atención primaria que a enero de 2014 habían recibido tratamiento con bifosfonatos durante al menos cinco años. Intervención: Se clasificó a las pacientes según su riesgo de nuevas fracturas, definido como presencia de antecedentes de fractura osteoporótica y/o tratamiento con un inhibidor de la aromatasa, y se analizó la continuidad o desprescripción del tratamiento con bifosfonatos a lo largo de cinco años de seguimiento. Mediciones principales: La incidencia acumulada de fracturas y la densidad de incidencia se calcularon y analizaron mediante regresión logística y modelos de Cox. Resultados: Se incluyeron 3.680 mujeres. No hubo diferencias significativas en el riesgo de fractura en mujeres de alto riesgo que desprescribieron el bisfosfonato comparado con aquellas que continuaron (hazard ratio [HR] 1,17, intervalo de confianza [IC] de 95% 0,87-1,58 para fracturas osteoporóticas totales). Sin embargo, los que discontinuaron con bajo riesgo tuvieron una menor incidencia de fractura que los que continuaron. Esta diferencia fue significativa para fracturas vertebrales (HR 0,64, IC 95% 0,47-0,88) y fracturas totales (HR 0,77, IC 95% 0,64-0,92). Conclusiones: Nuestros resultados sugieren que la desprescripción de bifosfonatos en mujeres que ya han recibido cinco años de tratamiento no aumenta el riesgo de fractura. En mujeres de bajo riesgo, la continuación de este tratamiento podría incluso favorecer la aparición de nuevas fracturas osteoporóticas.(AU)

Polypharmacy Patterns in Multimorbid Older People with Cardiovascular Disease: Longitudinal Study.

(1) Introduction: Cardiovascular disease is associated with high mortality, especially in older people. This study aimed to characterize the evolution of combined multimorbidity and polypharmacy patterns in older people with different cardiovascular disease profiles. (2) Material and methods: This longitudinal study drew data from the Information System for Research in Primary Care in people aged 65 to 99 years with profiles of cardiovascular multimorbidity. Combined patterns of multimorbidity and polypharmacy were analysed using fuzzy c-means clustering techniques and hidden Markov models. The prevalence, observed/expected ratio, and exclusivity of chronic diseases and/or groups of these with the corresponding medication were described. (3) Results: The study included 114,516 people, mostly men (59.6%) with a mean age of 78.8 years and a high prevalence of polypharmacy (83.5%). The following patterns were identified: Mental, behavioural, digestive and cerebrovascular; Neuropathy, autoimmune and musculoskeletal; Musculoskeletal, mental, behavioural, genitourinary, digestive and dermatological; Non-specific; Multisystemic; Respiratory, cardiovascular, behavioural and genitourinary; Diabetes and ischemic cardiopathy; and Cardiac. The prevalence of overrepresented health problems and drugs remained stable over the years, although by study end, cohort survivors had more polypharmacy and multimorbidity. Most people followed the same pattern over time; the most frequent transitions were from Non-specific to Mental, behavioural, digestive and cerebrovascular and from Musculoskeletal, mental, behavioural, genitourinary, digestive and dermatological to Non-specific. (4) Conclusions: Eight combined multimorbidity and polypharmacy patterns, differentiated by sex, remained stable over follow-up. Understanding the behaviour of different diseases and drugs can help design individualised interventions in populations with clinical complexity.

Improved management of cystitis in primary care following the implementation of a simple multifaceted intervention / Mejora en el manejo de las cistitis en atención primaria después de la implementación de una intervención multimodal simple

Objective: We assessed the impact of the implementation of a simple multifaceted intervention aimed at improving management of cystitis in primary care. Design: Quality control before and after study. Site: Primary care centres in Barcelona city provided by the Catalonian Institute of Health. Participants: The multifaceted intervention consisted of (1) creation of a group with a leader in each of the primary care centres, out of hours services, sexual and reproductive centres, and home visit service, (2) session on management of cystitis in each centre, (3) result feedback for professionals, and (4) provision of infographics for professionals and patients with urinary tract infections. Interventions started in November 2020 and ended in the summer of 2021. Main measurements: Variation in the prescription of first-line antibiotics, usage of antibiotics, and request for urine cultures before and after this intervention. Results: Training sessions took place in 93% of the centres. The use of first-line therapies cystitis increased by 6.4% after the intervention (95% confidence interval [CI], 5.7–7.1%). The use of nitrofurantoin in recurrent cystitis increased, mainly in out of hours service (8.7%; 95% CI, 5.2–12.2%). Urine cultures were more frequently requested after the intervention for recurrent cystitis in both primary care centres and out of hours services, with a 7.2% increase [95% CI, 5.9–8.5%), but also for uncomplicated urinary tract infections (3.1%; 95% CI, 1.8–4.4%). Conclusions: A low-intensity multifaceted intervention on management of cystitis, with strong institutional support, resulted in a better choice of antibiotic in antibiotic prescribing, but the intervention had less impact on the adequacy of urine cultures.(AU)

Emplazamiento: Centros de atención primaria de la ciudad de Barcelona proporcionados por el Institut Català de la Salut. Participantes: La intervención multimodal consistió en: (1) creación de un grupo de trabajo con líderes en cada uno de los equipos de atención primaria, servicios de urgencias, centros de atención sexual y reproductiva y servicio de atención domiciliaria, (2) sesión formativa sobre el manejo de las infecciones del tracto urinario en cada centro, (3) retorno de resultados a profesionales, y (4) difusión de infografías a profesionales y pacientes. Las intervenciones comenzaron en noviembre de 2020 y finalizaron en verano de 2021. Mediciones principales: Variación en la prescripción de antibióticos de primera línea, uso de antibióticos y solicitud de urocultivos antes y después de esta intervención. Resultados: Las sesiones de formación se realizaron en el 93% de los centros. La selección de fármacos de primera línea en cistitis aumentó en un 6,4% después de la intervención (intervalo de confianza [IC] 95%: 5,7-7,1%). El uso de nitrofurantoína en cistitis recurrente aumentó, principalmente en servicios de urgencias (8,7%; IC 95%: 5,2-12,2%). Las solicitudes de urocultivos aumentaron después de la intervención en equipos de atención primaria y servicios de urgencias en cistitis recurrentes (7,2%; IC 95%: 5,9-8,5%), pero también en cistitis simples (3,1%; IC 95%: 1,8-4,4%). Conclusiones: Una intervención multimodal de baja intensidad sobre el manejo de las cistitis junto con el apoyo institucional explícito mejoró claramente la selección de antibióticos, pero tuvo menos impacto en la adecuación de los urocultivos.(AU)

Combined Multimorbidity and Polypharmacy Patterns in the Elderly: A Cross-Sectional Study in Primary Health Care.

(1) Background: The acquisition of multiple chronic diseases, known as multimorbidity, is common in the elderly population, and it is often treated with the simultaneous consumption of several prescription drugs, known as polypharmacy. These two concepts are inherently related and cause an undue burden on the individual. The aim of this study was to identify combined multimorbidity and polypharmacy patterns for the elderly population in Catalonia. (2) Methods: A cross-sectional study using electronic health records from 2012 was conducted. A mapping process was performed linking chronic disease categories to the drug categories indicated for their treatment. A soft clustering technique was then carried out on the final mapped categories. (3) Results: 916,619 individuals were included, with 93.1% meeting the authors' criteria for multimorbidity and 49.9% for polypharmacy. A seven-cluster solution was identified: one non-specific (Cluster 1) and six specific, corresponding to diabetes (Cluster 2), neurological and musculoskeletal, female dominant (Clusters 3 and 4) and cardiovascular, cerebrovascular and renal diseases (Clusters 5 and 6), and multi-system diseases (Cluster 7). (4) Conclusions: This study utilized a mapping process combined with a soft clustering technique to determine combined patterns of multimorbidity and polypharmacy in the elderly population, identifying overrepresentation in six of the seven clusters with chronic disease and chronic disease-drug categories. These results could be applied to clinical practice guidelines in order to better attend to patient needs. This study can serve as the foundation for future longitudinal regarding relationships between multimorbidity and polypharmacy.

Medication-Related Problems in Older People with Multimorbidity in Catalonia: A Real-World Data Study with 5 Years' Follow-Up.

Aging, multimorbidity, and polypharmacy are associated with medication-related problems (MRPs). This study aimed to assess the association that multimorbidity and mortality have with MRPs in older people over time. We followed multimorbid, older (65-99 years) people in Catalonia from 2012 to 2016, using longitudinal data and Cox models to estimate adjusted hazard ratios (HR). We reviewed electronic health records to collect explanatory variables and MRPs (duplicate therapy, drug-drug interactions, potentially inappropriate medications (PIM), and contraindicated drugs in chronic kidney disease (CKD) or liver disease). There were 723,016 people (median age: 74 years; 58.9% women) who completed follow-up. We observed a significant (p < 0.001) increase in the proportion with at least one MRP (2012: 66.9% to 2016: 75.5%); contraindicated drugs in CKD (11.1 to 18.5%) and liver disease (3.9 to 5.3%); and PIMs (62.5 to 71.1%), especially drugs increasing fall risk (67.5%). People with ≥10 diseases had more MRPs (in 2016: PIMs, 89.6%; contraindicated drugs in CKD, 34.4%; and in liver disease, 9.3%). All MRPs were independently associated with mortality, from duplicate therapy (HR 1.06; 95% confidence interval (CI) 1.04-1.08) to interactions (HR 1.60; 95% CI 1.54-1.66). Ensuring safe pharmacological treatment in elderly, multimorbid patient remains a challenge for healthcare systems.

Medication-related problems in older people in Catalonia: A real-world data study.

PURPOSE: The aim of this study was to determine medication-related problems (MRPs) in primary care patients over 65 years of age. METHODS: Cross-sectional study based on the electronic health records of patients (65-99 years of age) visited in 284 primary health care centers during 2012 in Catalonia. VARIABLES: age, sex, sociodemographic variables, number of drugs, kidney and liver function and MRPs (duplicate therapy, drug-drug interactions, potentially inappropriate medications [PIMs] and drugs contraindicated in chronic kidney disease and in liver diseases). Unconditional logistic regression models were used to identify the factors associated with MRPs in patients with multimorbidity. RESULTS: 916 619 older people were included and 853 085 of them met the criteria for multimorbidity. Median age was 75 years and 57.7% of them were women. High percentages of MRPs were observed: PIMs (62.8%), contraindicated drugs in chronic kidney disease (12.1%), duplicate therapy (11.1%), contraindicated drugs in liver diseases (4.2%), and drug-drug interactions (1.0%). These numbers were higher in the subgroup of patients with ≥10 diseases. The most common PIMs were connected to drugs that increase the risk of fall (66.8%), antiulcer agents without criteria for gastroprotection (40.6%), and the combination of drugs with anticholinergic effects (39.7%). In the multivariate analysis, the variables associated with all MRPs among the patients with multimorbidity were the number of drugs and the number of visits. CONCLUSIONS: The coexistence of multimorbidity and polypharmacy is associated with an elevated risk of MRPs in older people. Medication safety for older patients constitutes a pressing concern for health services.

Multimorbidity patterns, polypharmacy and their association with liver and kidney abnormalities in people over 65 years of age: a longitudinal study.

BACKGROUND: The implementation of individual clinical practice guidelines in patients with multimorbidity often results in polypharmacy. Our aim was to analyse medication use according to longitudinal multimorbidity patterns (MP) and determine during a 5-year period (2012-16) which MP are associated with abnormal liver and kidney function in primary care patients over 65 years of age living in Catalonia. METHODS: Design: Longitudinal study (years 2012 to 2016) based on the electronic health records contained in Information System for Research in Primary Care database of the Catalan Institute of Health (SIDIAP). VARIABLES: age, sex, MP, medication and polypharmacy (drug exposure obtained from the Pharmacy Invoice Registry). Medicines were classified in accordance with the Anatomical Therapeutic Chemical Classification System (ATC). Glomerular filtration rate was used to determine abnormal kidney function, and serum levels of alkaline phosphatase, alanine transaminase and gamma-glutamyl transpeptidase were used to diagnose abnormal liver function. STATISTICS: For medication use in MP, we calculated annual mean packages of each drug in each MP, and observed/expected ratios were obtained by dividing mean packages in the cluster by mean packages of the same drug in the overall population. Logistic regression models were fitted to estimate the association between MP at baseline and abnormal kidney and liver function tests during follow up. RESULTS: Nine hundred sixteen thousand six hundred nineteen patients were included, and 743,827 completed the follow up. We identified one polypharmacy profile per MP, and concluded that the most prescribed drugs in each pattern corresponded to the diseases overrepresented in that specific MP. The median of drugs ranged from 3 (Cluster 1 - Non-Specific) to 8 (Cluster 10 - Multisystem Pattern). Abnormal kidney function was most commonly observed in the Cluster 4 - Cardio-Circulatory and Renal (Odds Ratio [OR] 2.19; Confidence interval [CI] 95% 2.15-2.23) and Cluster 3 - Minority Metabolic Autoimmune-Inflammatory (OR 2.16; CI 95% 2.12-2.20) MP. A higher risk of abnormal liver function was observed in the Cluster 8 - Digestive (OR 3.39; CI 95% 3.30-3.49), and Cluster 4 - Cardio-Circulatory and Renal (OR 1.96; CI 95% 1.91-2.02) MP. CONCLUSIONS: A higher risk of abnormal kidney and liver function was observed in specific MP. The long-term characterisation of MP and polypharmacy illustrates the burden of chronic multimorbidity and polypharmacy in the elderly population.

Effectiveness and safety of drugs used for stroke prevention in a cohort of non-valvular atrial fibrillation patients from a primary care electronic database.

PURPOSE: The aim of this study was to assess effectiveness and safety of antithrombotics for stroke prevention in non-valvular atrial fibrillation in real-use conditions. METHODS: We used a population-based retrospective cohort study. Information emerges from SIDIAP, a database containing anonymized information from electronic health records from 274 primary healthcare centres of the Catalan Health Institute, Catalonia (Spain), with a reference population of 5 835 000 people. Population includes all adults with a new diagnosis of non-valvular atrial fibrillation registered in SIDIAP from 2007 to 2012. The main outcome of antithrombotics' effectiveness was stroke. The main outcomes of safety were cerebral and gastrointestinal haemorrhages. We also estimated all-cause mortality. We used multivariable Cox proportional hazard models to examine association between antithrombotic treatment and main outcomes. RESULTS: We included 22 205 subjects with non-valvular atrial fibrillation; 40.8% initiated on vitamin K antagonists (VKA), 33.4% on antiplatelets and 25.8% untreated. We found stroke-risk reduction with VKA, hazard ratio (HR) 0.72 (95% confidence interval (CI), 0.58-0.91), also seen in patients with CHADS2 ≥ 2, HR 0.65 (95%CI, 0.49-0.86), and CHA2 DS2 -VASc ≥ 2, HR 0.66 (95%CI, 0.52-0.84). We observed a higher risk of digestive bleeding with antiplatelets, HR 1.32 (95%CI, 1.01-1.73). Both VKA and antiplatelets were associated with reduction of all-cause mortality risk; HR 0.55 (95%CI, 0.49-0.62) and HR 0.89 (95%CI, 0.80-0.97), respectively. CONCLUSIONS: This study found a stroke-risk reduction associated with VKA and an increased risk of gastrointestinal bleeding associated with platelet-aggregation inhibitors in comparison with untreated patients. Both antithrombotic groups showed a reduction in all-cause mortality. Copyright © 2016 John Wiley & Sons, Ltd.

Effectiveness, safety and costs of thromboembolic prevention in patients with non-valvular atrial fibrillation: phase I ESC-FA protocol study and baseline characteristics of a cohort from a primary care electronic database.

PURPOSE: Atrial fibrillation is the most common arrhythmia. Its management aims to reduce symptoms and to prevent complications through rate and rhythm control, management of concomitant cardiac diseases and prevention of related complications, mainly stroke. The main objective of Effectiveness, Safety and Costs in Atrial Fibrillation (ESC-FA) study is to analyse the drugs used for the management of the disease in real-use conditions, particularly the antithrombotic agents for stroke prevention. The aim of this work is to present the study protocol of phase I of the ESC-FA study and the baseline characteristics of newly diagnosed patients with atrial fibrillation in Catalonia, Spain. PARTICIPANTS: The data source is System for the Improvement of Research in Primary Care (SIDIAP) database. The population included are all patients with non-valvular atrial fibrillation diagnosis registered in the electronic health records during 2007-2012. FINDINGS TO DATE: A total of 22,585 patients with non-valvular atrial fibrillation were included in the baseline description. Their mean age was 72.8 years and 51.6% were men. The most commonly prescribed antithrombotics were vitamin K antagonists (40.1% of patients) and platelet aggregation inhibitors (32.9%); 25.3% had not been prescribed antithrombotic treatment. Age, gender, comorbidities and co-medication at baseline were similar to those reported for previous studies. FUTURE PLANS: The next phase in the ESC-FA study will involve assessing the effectiveness and safety of antithrombotic treatments, analysing stroke events and bleeding episodes' rates in our patients (rest of phase I), describing the current management of the disease and its costs in our setting, and assessing how the introduction of new oral anticoagulants changes the stroke prevention in non-valvular atrial fibrillation.

Haemophagocytic syndrome and paradoxical reaction to tuberculostatics after treatment with infliximab.

CASE: A 44-year-old man was diagnosed with ankylosing spondylitis, on treatment with infliximab. After three doses, he was admitted to hospital with fever, fatigue and nausea. A bone marrow biopsy confirmed haemophagocytic syndrome. He was treated with immunoglobulin, cyclosporine and corticosteroids. CT scan revealed tuberculosis. Tuberculostatic treatment was started 26 days after admission. One month later, he was transferred intensive care with septic shock and acute respiratory distress syndrome. After improvement, he was transferred to the medical ward and later discharged. Two weeks after discharge, he was readmitted with a suspected paradoxical reaction (PR) to tuberculostatics and treated with prednisone. He was discharged 15 days later. CONCLUSIONS: In patients treated with anti-TNF therapy it may be advisable to monitor the signs and symptoms of tuberculosis. HPS is a rare complication of rheumatic diseases. The possibility of developing a PR in immunosuppressed patients treated with antituberculous should be considered.

[Pharmaceutical care strategies to prevent medication errors]. / Estrategias de atención farmacéutica para prevenir errores de medicación.

OBJECTIVE: To evaluate the impact of implementing new programs to improve the quality of the pharmaceutical care and unit-dose distribution system for in-patients. MATERIAL AND METHODS: An observational and prospective study was carried out in a general hospital during two different six-monthly period. Transcription and dispensation errors were evaluated in twelve wards during the first six months. Then, two new measures were introduced: the first- reference ward-pharmacist and the second-a new protocol for checking medication on the ward. Results were evaluated by SPSS v. 14 program. RESULTS: In the transcription evaluation, units without a ward pharmacist did not improve. Transcription errors significantly decreased in three units: gynaecology-urology (3.24% vs. 0.52%), orthopaedic (2% vs. 1.69%) and neurology-pneumology (2.81% vs. 2.02%). In dispensing, only units with the new protocol decreased their medication errors (1.77% vs. 1.24%). CONCLUSIONS: The participation of pharmacists in multidisciplinary teams and exhaustive protocols for dispensing medication were effective in detecting and decreasing medication errors in patients.
