Uso de antimicrobianos en la unidad de cuidados intensivos de un hospital público de Loreto / Use of antimicrobials in the intensive care unit of a Loreto public hospital

RESUMEN Introducción. El uso inapropiado de antimicrobianos en las unidades de cuidados intensivos (UCI) contribuye a la resistencia bacteriana. Objetivo. El propósito del presente estudio fue medir el uso y tipo de antimicrobianos en los pacientes hospitalizados en la Unidad de Cuidados Intensivos del Hospital Regional de Loreto (HRL). Métodos. Estudio de tipo descriptivo. Revisamos 120 historias clínicas en pacientes de UCI-HRL desde enero a junio 2023. Resultados. La mayoría de los pacientes usaron antimicrobianos (74,2%), indicados por shock séptico (42,7%), de 1 a 3 antimicrobianos (93,2%), con terapia de 1 a 3 días (45%). Del total de antimicrobianos usados, la mayor proporción fueron bactericidas 89 (90,4%), de la familia de cefalosporinas (33,1%) y carbapenémicos (23,5%); los fármacos más empleados fueron ceftriaxona (26,5%) y meropenem (21,1%) por vía intravenosa (90,4%). Conclusión. La mayor proporción de pacientes hospitalizados usan antimicrobianos de la familia de cefalosporinas y carbapenémicos.

ABSTRACT Introduction. Inappropriate use of antimicrobials in the Intensive Care Unit (ICU) contributes to bacterial resistance. Objective. The purpose of the present study was to measure the use and type of antimicrobials in patients hospitalized in the Intensive Care Unit of the Loreto Regional Hospital (HRL). Methods. Descriptive study. We reviewed 120 medical records in ICU-HRL patients from January to June 2023. Results. Most patients used antimicrobials (74.2%), indicated for septic shock (42.7%), 1 to 3 antimicrobials (93.2%), with therapy of 1 to 3 days (45%). Of the total number of antimicrobials used, the greatest proportion were bactericides 89 (90.4%), from the cephalosporin family (33.1%) and carbapenemics (23.5%); the most commonly used drugs were ceftriaxone (26.5%) and meropenem (21.1%) by the intravenous route (90.4%). Conclusion. The highest proportion of hospitalized patients use antimicrobials of the cephalosporin and carbapenemics family.

Rapid drug susceptibility testing and treatment outcomes for multidrug-resistant tuberculosis in Peru.

SETTING: The detection of multidrug-resistant tuberculosis (MDR-TB) using rapid drug susceptibility testing (DST) has increased steadily in recent years in Peru, from 9216 tests in 2010 to 27 021 tests in 2015. Research examining the impact of rapid DST on treatment outcomes is required. OBJECTIVE: To evaluate the association between rapid DST use (nitrate reductase assay, microscopic observation drug susceptibility assay [MODS] and GenoType® MTBDRplus) and treatment outcomes and mortality in MDR-TB patients in Peru. DESIGN: Retrospective cohort study of patients diagnosed with pulmonary MDR-TB between 2010 and 2013 (with treatment outcomes up to December 2015) using the electronic registry of the Peruvian National TB Programme. RESULTS: A total of 2671 MDR-TB patients were included; the median age was 27 years, 2.8% were co-infected with the human immunodeficiency virus. Use of rapid DST was associated with a 40% increase in the adjusted odds of treatment success (aOR 1.40, 95%CI 1.19-1.64) and a 54% reduction in mortality (aOR 0.46, 95%CI 0.33-0.64). Higher treatment success rates were driven by MODS and GenoType® MTBDRplus testing (aORs for unsuccessful outcomes respectively 0.68 and 0.66). CONCLUSION: The use of rapid DST (MODS and MTBDRplus) to diagnose MDR-TB was associated with a reduction in the odds of death and a substantial increase in the odds of treatment success.

The Innovative Socio-economic Interventions Against Tuberculosis (ISIAT) project: an operational assessment.

SETTING: Tuberculosis (TB) affected households in impoverished shantytowns, Lima, Peru. OBJECTIVE: To evaluate socio-economic interventions for strengthening TB control by improving uptake of TB care and prevention services. DESIGN: Barriers to TB control were characterised by interviews with TB-affected families. To reduce these barriers, a multidisciplinary team offered integrated community and household socio-economic interventions aiming to: 1) enhance uptake of TB care by education, community mobilisation and psychosocial support; and 2) reduce poverty through food and cash transfers, microcredit, microenterprise and vocational training. An interim analysis was performed after the socio-economic interventions had been provided for 2078 people in 311 households of newly diagnosed TB patients for up to 34 months. RESULTS: Poverty (46% earned
