Multilevel analysis identifying the factors associated with RSV detection in infants admitted for viral bronchiolitis in the era of the COVID-19 pandemic.

OBJECTIVES: To identify factors independently associated with respiratory syncytial virus (RSV) detection in infants admitted for viral bronchiolitis during 3 consecutive years, before and during the COVID-19 pandemic, in Bogota, Colombia, a middle-income country with a subtropical highland climate. METHODS: An analytical cross-sectional study was conducted before and during the COVID-19 pandemic, including patients with a diagnosis of viral bronchiolitis admitted to all the hospitals of the city between January 2019 and November 2021. We evaluated a set of a priori-selected predictor variables that included individual, healthcare system, meteorological, air pollutant, and COVID-19 variables. Since the variables analyzed are hierarchical in nature, multilevel modeling was used to identify factors independently associated with detection of RSV as the causative agent of viral bronchiolitis. RESULTS: A total of 13,177 patients were included in the study. After controlling for potential confounders, it was found that age (odds ratio [OR] 0.86; 95% confidence interval [CI] 0.76-0.97), a third level of medical care institution (OR 3.05; 95% CI 1.61-5.76), temperature (OR 1.60; 95% CI 1.24-2.07), rainfall (OR 1.003, 95% CI 1.001, 1.005), NO2 (OR 0.97; 95% CI 0.95-0.99), CO (OR 0.99; 95% CI 0.99-0.99), and COVID-19 pandemic period (OR 0.84, 95% CI 0.71-0.99) were independently associated with RSV detection in our sample of patients. CONCLUSIONS: The identified factors associated with RSV detection provide additional scientific evidence that may be useful in the development of specific interventions aimed at ameliorating or preventing the impact of RSV in Bogota and probably other similar low- to middle-income countries in high-risk infants.

Adherence to guidelines on the use of amoxicillin for treatment of ambulatory pneumonia in children younger than 5 years, Colombia, 2017-2019.

Objectives: To determine the level of adherence to clinical guidelines in prescribing amoxicillin to children younger than 5 years with pneumonia in outpatient settings in Colombia from 2017 to 2019, and assess the factors associated with adherence. Methods: This was a cross-sectional study of secondary data from the Colombian Integrated Social Protection Information System database. Adherence was defined as prescription of oral amoxicillin for bacterial and unspecified pneumonia and non-prescription for viral pneumonia. Variables examined included: age (< 1 year, 1-4 years) of child; sex; cause of pneumonia (bacterial, viral, unspecified); region (Andean, Amazonian, Pacific, Caribbean, Insular, Orinoquian); and payment mechanism (without prior authorization, capitation, direct payment, pay per case, pay for event). Results: Of 215 925 cases of community-acquired pneumonia reported during 2017-2019, 64.8% were from the Andean region, 73.9% were bacterial pneumonia and 1.8% were viral pneumonia. Adherence to guidelines was observed in 5.8% of cases: this was highest for children diagnosed with viral (86.0%) compared with bacterial (2.0%) pneumonia. For children diagnosed with bacterial pneumonia, 9.4% were prescribed any antibiotic. A greater proportion of children covered by capitated payments (22.3%) were given treatment consistent with the guidelines compared with payment for event (1.3%). Conclusion: In this first study from Colombia, adherence to guidelines for outpatient treatment of children with bacterial pneumonia was low and was better for viral pneumonia. Further qualitative studies are needed to explore the reasons for this lack of adherence and why bacterial pneumonia was the most commonly reported etiology.

[RESUMEN]. Objetivos. Determinar el nivel de adherencia a las directrices clínicas al momento de prescribir amoxicilina a menores de 5 años con neumonía en entornos de atención ambulatoria en Colombia entre el 2017 y el 2019, así como evaluar los factores asociados con la adherencia. Métodos. Este fue un estudio transversal de datos secundarios de la base de datos del Sistema Integral de Información de la Protección Social de Colombia. La adherencia se definió como la prescripción de amox- icilina por vía oral para las neumonías bacterianas y no especificadas, y la ausencia de prescripción para las neumonías virales. Las variables examinadas incluyeron: edad (< 1 año, 1 a 4 años); sexo; causa de la neumonía (bacteriana, viral, no especificada); región (andina, amazónica, Pacífico, Caribe, insular, Orinoco); y mecanismo de pago (sin autorización previa, capitación, pago directo, pago por caso, pago por evento). Resultados. De 215 925 casos de neumonía adquirida en la comunidad notificados durante el período 2017- 2019, el 64,8% correspondieron a la región andina, el 73,9% a neumonía bacteriana y el 1,8% a neumonía viral. Se observó la adherencia a las directrices en el 5,8% de los casos: esta cifra fue más alta para la población infantil diagnosticada con neumonía viral (86,0%) que para la diagnosticada con neumonía bacte- riana (2,0%). En el caso de la población infantil diagnosticada con neumonía bacteriana, al 9,4% se le recetó algún antibiótico. La proporción de población infantil cubierta por pagos capitados (22,3%) que recibió un tratamiento en consonancia con las directrices fue mayor que la de la población cubierta por pagos por evento (1,3%). Conclusión. En este primer estudio de Colombia, la adherencia a las directrices sobre el tratamiento ambula- torio de la población infantil con neumonía bacteriana fue bajo, en tanto que resultó superior en el caso de la neumonía viral. Se necesitan más estudios cualitativos para indagar sobre los motivos de esta falta de adher- encia y las razones por las cuales la neumonía bacteriana fue la etiología notificada con mayor frecuencia.

Diagnostic accuracy of rapid tests for sexually transmitted infections in symptomatic women.

OBJECTIVE: To determine the diagnostic accuracy of tests developed for use at the point of care for Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and syphilis in women having symptoms of lower urinary tract infection. METHODS: Cross-sectional study involving sexually active 14-49-year-old women with lower urinary tract infection symptoms consulting during 2010 at a private health clinic and at two public hospitals in Bogotá, Colombia. Pregnant women, those with a previous hysterectomy or those who received antibiotics during the previous 7 days were excluded. Sequential sampling was used; sample size: 1500 women. The ACON NG and CT duo test combo and the ACON individual test plates for NG and separately for CT were used. The QuickVue Chlamydia rapid test (RT) was also used. All of them were compared with nucleic acid amplification methods. The SD Bioline 3.0 and ACON test for syphilis were evaluated and compared with serological tests. Sensitivity and specificity were estimated. RESULTS: CT RTs had a sensitivity that ranged between 22.7% and 37.7% and specificity between 99.3% and 100%. Sensitivity for NG with ACON Duo was 12.5% and specificity 99.8%. Tests for syphilis had a sensitivity of 91.6-100% and a specificity of 99.7-97.8%. CONCLUSIONS: The RTs studied are not useful for screening for NG at the point of care. In case of CT a recommendation about their use in routine care should be supported by a cost-effectiveness analysis. In screening populations at high risk of sexually transmitted infections or pregnant women, the RTs for syphilis should be used.
