Outpatient parenteral antimicrobial therapy with continuous infusion of meropenem: A retrospective analysis of three years of clinical experience / Tratamiento antimicrobiano domiciliario endovenoso con infusión continua de meropenem: un análisis restrospectivo de tres años de experiencia clínica

Introduction: Data regarding outpatient parenteral antimicrobial therapy (OPAT) with continuous infusion of meropenem (CIM) remain scarce and controversial. We aimed to analyze its outcomes. Methods: We conducted a retrospective analysis of a cohort of patients who received OPAT with CIM during a three-year period at a single center in northwest Spain. Demographics, clinical data and OPAT outcomes were recorded. Results: Since January 2017–December 2019, 34 patients received 35 OPAT episodes with CIM. The median age was 75 years, and 18 (51.4%) had a Charlson comorbidity index>2. Twelve (34.3%) had respiratory infection, 11 (31.4%) urinary tract infection, and 12 (34.3%) other infections. Twenty-one (60%) received a dose of 6g/day, and 27 (77.1%) received combined antibiotic therapy. The duration of OPAT with CIM was 10 median days. Pseudomonas aeruginosa was the most frequently (34.3%) isolated microorganism and 10 (28.6%) infections were polymicrobial. During OPAT and hospital at home unit admission, 4 (11.4%) patients had any adverse reaction that required CIM withdrawal, 2 (5.7%) were readmitted, and 3 (8.8%) died (2 infection-related deaths). After 30 days from discharge 6 (18.8%) of 32 not-censored patients had unplanned readmissions (2 infection-related), 6 (18.8%) developed recurrence (3 relapses, 3 reinfections) and 1 (3.1%) died (none-infection-related death). Twenty-three (71.9%) of these 32 patients did not experience unplanned readmission, recurrence or death. Conclusion: CIM can be an option to be administrated in OPAT programs in selected patients. Further studies are warranted to increase evidence regarding its use, and to externally validate our findings.(AU)

Introducción: Los datos sobre el tratamiento antimicrobiano domiciliario endovenoso (TADE) con infusión continua de meropenem (ICM) son escasos y controvertidos. Nuestro objetivo fue analizar sus resultados. Métodos: Realizamos un análisis retrospectivo de una cohorte de pacientes que recibieron TADE con ICM durante tres años en un centro del noroeste de España. Se registraron datos demográficos, clínicos y resultados. Resultados: Desde enero de 2017 a diciembre de 2019, 34 pacientes recibieron 35 episodios de TADE con ICM. La mediana de edad fue de 75 años y 18 (51,4%) tenían un índice de comorbilidad de Charlson>2. Doce (34,3%) tenían infección respiratoria, 11 (31,4%) urinaria y 12 (34,3%) otras infecciones. Veintiuno (60%) recibieron una dosis de 6g/día y 27 (77,1%) antibioterapia combinada. La duración mediana del TADE con ICM fue de 10 días. Pseudomonas aeruginosa fue el microorganismo aislado más frecuentemente (34,3%) y 10 (28,6%) infecciones fueron polimicrobianas. Durante el TADE, 4 (11,4%) pacientes presentaron alguna reacción adversa que requirió retirada de ICM, 2 (5,7%) reingresaron y 3 (8,8%) fallecieron (2 muertes relacionadas con infección). Tras 30 días desde el alta, 6 (18,8%) de 32 pacientes tuvieron reingresos no programados (2 relacionados con infección), 6 (18,8%) desarrollaron recurrencia (3 recidivas, 3 reinfecciones) y 1 (3,1%) falleció (sin relación con infección). Veintitrés (71,9%) de 32 pacientes no experimentaron reingreso no programado, recidiva o muerte. Conclusión: La ICM puede ser una opción para ser administrada en programas de TADE en pacientes seleccionados. Se necesitan más estudios para aumentar la evidencia sobre su uso y validar externamente nuestros hallazgos.(AU)

[Randomized controlled clinical trial of a home care unit intervention to reduce readmission and death rates in patients discharged from hospital following admission for heart failure]. / Ensayo clínico aleatorizado y controlado para valorar una intervención por una unidad de hospitalización domiciliaria en la reducción de reingresos y muerte en pacientes dados de alta del hospital tras un ingreso por insuficiencia cardiaca.

INTRODUCTION AND OBJECTIVES: To determine the effectiveness of a primarily educational intervention in heart failure (HF) patients implemented in a home care unit. METHODS: This randomized controlled clinical trial involved 279 HF patients who were discharged from a tertiary-care hospital between February 2001 and June 2002. Patients with dementia, terminal non-cardiac disease, or chronic obstructive pulmonary disease were excluded. Data collected included the cause of cardiac decompensation. A primarily educational intervention was implemented in the patient's home for up to 15 days after hospital discharge. Treatment was adjusted during the first week if necessary. The primary outcome measure was the 1-year cumulative incidence of readmission or death. Secondary measures were the incidence of readmission, mortality, and emergency department admission. Telephone interviews were carried out 3, 6 and 12 months after discharge, and clinical records were updated when necessary. Emergency department admission in the first 6 months was monitored. RESULTS: At 1-year follow-up, 62 of the 137 patients (45.3%) in the intervention group had been readmitted or died, compared with 75 of the 142 (52.8%) in the control group, (relative risk=0.86, P=.232). Among patients who suffered decompensation because failure to adhere to treatment, 16 of the 45 (35.6%) in the intervention group were readmitted or died, compared with 34 of the 56 (60.7%) control group patients (relative risk=0.59, P=.016). CONCLUSIONS: This intervention is feasible but, when applied indiscriminately to every discharged heart failure patient, the best that can be expected is only a modest reduction in readmission and death rates, which, in this study in particular, did not achieve statistical significance.

Introducción y objetivos. Evaluar la eficacia de una intervención de educación en pacientes con insuficiencia cardiaca (IC) realizada por hospitalización a domicilio. Métodos. Ensayo clínico aleatorizado y controlado. Se incluyó a 279 pacientes con diagnóstico clínico de IC dados de alta de un hospital terciario entre febrero de 2001 y junio de 2002. Se excluyó a los pacientes con demencias, enfermedad terminal no cardiológica o enfermedad pulmonar obstructiva crónica. La información recogida incluyó las causas de la descompensación. La intervención fue fundamentalmente de tipo educativo, en el domicilio del participante, y se extendió hasta 15 días después del alta. Se realizaron ajustes de tratamiento durante la primera semana cuando fue necesario. El objetivo principal fue determinar la incidencia acumulada de reingreso o muerte. Los objetivos secundarios fueron la incidencia de reingreso y la mortalidad, así como la utilización de los servicios de urgencia. Se llevó a cabo un seguimiento telefónico a los 3, 6 y 12 meses, y una revisión de las historias clínicas si era necesario. Asimismo, se valoró la utilización de servicios de urgencias los primeros 6 meses. Resultados. Al año, 62 pacientes de 137 (45,3%) ingresaron o murieron en el grupo de intervención, en comparación con 75 de 142 (52,8%) en el grupo control (p = 0,232; riesgo relativo [RR] = 0,86). En los pacientes que se descompensaron por incumplimiento terapéutico, 16 de 45 (35,6%) ingresaron o murieron en el grupo de intervención, en comparación con 34 de 56 (60,7%) en el grupo control (p = 0,016; RR = 0,59). Conclusiones. Esta intervención es factible pero, administrada de manera indiscriminada a todo paciente dado de alta por IC, en el mejor de los casos sólo podemos esperar un beneficio modesto, que en este estudio en particular no llegó a alcanzar significación estadística (AU)
