ABSTRACT
Introduction: The inappropriate use of antibiotics is associated with a greater risk for antimicrobial resistance, high health care costs, adverse events, and worse clinical outcomes. Objective: To determine the prescription patterns and approved and nonapproved indications for macrolides in a group of patients from Colombia. Materials and methods: This was a cross-sectional study on the indications for the use of macrolides in outpatients registered in a drug-dispensing database of approximately 8.5 million people affiliated with the Colombian health system. Sociodemographic, pharmacological, and clinical variables were considered. Results: A total of 9.344 patients had received a macrolide prescription; their median age was 40.1 years (interquartile range: 27.1-53.3 years) and 58.3% were women. The most commonly prescribed macrolide was azithromycin (38.8%) most frequently for Helicobacter pylori infection (15.9%) and pneumonia treatment (15.8%). A total of 31.3% of the prescriptions were used for unapproved indications: common cold (7.8%), COVID-19 (4.0%), and acute bronchitis (3.5%). Residence in the Caribbean region (OR=1.17; 95%CI 1.05-1.31), dental prescriptions (OR=2.75; 95%CI 1.91-3.96), presence of chronic respiratory comorbidities (OR=1.30; 95%CI 1.08-1.56), and prescription of erythromycin (OR=3.66; 95%CI 3.24-4.14) or azithromycin (OR=2.15; 95%CI 1,92-2.41) were associated with a higher probability of macrolide use for unapproved indications while being 18-64 years old (OR=0.81; 95%CI 0.71-0.93) or 65 years or older (OR=0.77; 95%CI 0.63-0.94) and residing in Bogotá-Cundinamarca (OR=0.74; 95%CI 0.65-0.85) were associated with reduced risk. Conclusions: Most patients received macrolides for respiratory tract infections; erythromycin and azithromycin were used for unapproved indications in people under 18 years of age and those with chronic respiratory diseases.
Introducción. El uso inadecuado de antibióticos se asocia con aumento de la resistencia antimicrobiana, mayores costos de atención médica, más efectos adversos y peores resultados clínicos. Objetivo. Determinar los patrones de prescripción y las indicaciones aprobadas y no aprobadas para macrólidos en un grupo de pacientes en Colombia. Materiales y métodos. Se hizo un estudio de corte transversal sobre las indicaciones de uso de macrólidos en pacientes ambulatorios a partir de una base de datos de dispensación de medicamentos de 8,5 millones, aproximadamente, de personas afiliadas al sistema de salud de Colombia. Se consideraron variables sociodemográficas, farmacológicas y clínicas. Resultados. Se encontraron 9.344 pacientes que habían recibido prescripción de macrólidos; su mediana de edad era de 40,1 años (rango intercuartílico: 27,1-53,3 años) y el 58,3 % correspondía a mujeres. El macrólido más prescrito fue la azitromicina (38,8 %) y los usos más frecuentes fueron el tratamiento de la infección por Helicobacter pylori (15,9 %) y la neumonía (15,8 %). El 31,3 % de las prescripciones correspondía a indicaciones no aprobadas, destacándose el resfriado común (7,8 %), la Covid-19 (4,0 %) y la bronquitis aguda (3,5 %). La residencia en la región Caribe (OR=1,17; IC95% 1,05-1,31), las prescripciones odontológicas (OR=2,75; IC95% 1,91-3,96), las comorbilidades respiratorias crónicas (OR=1,30; IC95% 1,08-1,56), y la prescripción de eritromicina (OR=3,66; IC95% 3,24-4,14) o azitromicina (OR=2,15; IC95% 1,92-2,41), se asociaron con una mayor probabilidad de recibir macrólidos para indicaciones no aprobadas, en tanto que tener entre 18 y 64 años (OR=0,81; IC95% 0,71-0,93), 65 o más años (OR=0,77; IC95% 0,63-0,94) y residir en Bogotá-Cundinamarca (OR=0,74; IC95% 0,65-0,85) reducían dicho riesgo. Conclusiones. La mayoría de los pacientes recibieron macrólidos para infecciones del sistema respiratorio; la eritromicina y la azitromicina se prescribieron en indicaciones no aprobadas en menores de 18 años y en quienes presentaban enfermedades respiratorias crónicas.

The impact of COVID-19 prompted a race to find a treatment that would reduce its mortality. Most studies have not shown favorable results for many of these drugs, but they are still used. The aim as to determine the differences and similarities in the hospital pharmacological management of patients with COVID-19 according to sex, age group, and geographical region of Colombia, 2020-2021. Descriptive cross-sectional study was conducted on the prescription patterns of the medications given to patients diagnosed with COVID-19 treated in eight clinics in Colombia between 6 March 2020 and 31 May 2021. We performed a descriptive analysis of the sociodemographic, clinical, and pharmacological variables of the patients. A total of 8596 patients from 170 cities were identified, with a median age of 53.0 years and 53.3% of them men. A total of 24.3% required care in the intensive care unit, and 18.7% required invasive mechanical ventilation. The most commonly used drugs for the treatment of COVID-19 were systemic corticosteroids (63.6%), followed by colchicine (12.8%), azithromycin (8.9%), and ivermectin (6.4%). Corticosteroids, anticoagulants, colchicine, azithromycin, ivermectin, and hydroxychloroquine were prescribed more frequently in men, and their overall use increased with age. There were differences in prescriptions between geographic regions. The majority of patients were managed with medications included in the management guidelines. There were differences between sexes, age groups, and geographical regions.
