Ten Issues to Update in Nosocomial or Hospital-Acquired Pneumonia: An Expert Review.

Nosocomial pneumonia, or hospital-acquired pneumonia (HAP), and ventilator-associated pneumonia (VAP) are important health problems worldwide, with both being associated with substantial morbidity and mortality. HAP is currently the main cause of death from nosocomial infection in critically ill patients. Although guidelines for the approach to this infection model are widely implemented in international health systems and clinical teams, information continually emerges that generates debate or requires updating in its management. This scientific manuscript, written by a multidisciplinary team of specialists, reviews the most important issues in the approach to this important infectious respiratory syndrome, and it updates various topics, such as a renewed etiological perspective for updating the use of new molecular platforms or imaging techniques, including the microbiological diagnostic stewardship in different clinical settings and using appropriate rapid techniques on invasive respiratory specimens. It also reviews both Intensive Care Unit admission criteria and those of clinical stability to discharge, as well as those of therapeutic failure and rescue treatment options. An update on antibiotic therapy in the context of bacterial multiresistance, in aerosol inhaled treatment options, oxygen therapy, or ventilatory support, is presented. It also analyzes the out-of-hospital management of nosocomial pneumonia requiring complete antibiotic therapy externally on an outpatient basis, as well as the main factors for readmission and an approach to management in the emergency department. Finally, the main strategies for prevention and prophylactic measures, many of them still controversial, on fragile and vulnerable hosts are reviewed.

Economic burden of skin and skin structure infections due to Gram-positive bacteria in patients on hospital at home-based outpatient parenteral antibiotic therapy (OPAT) / Carga económica de la infección de piel y partes blandas por microorganismos grampositivos en pacientes en unidades de hospitalización a domicilio con tratamiento antimicrobiano domiciliario endovenoso (TADE)

Objective: To describe and quantify resource use and direct health costs associated with skin and skin structure infections (SSSIs) caused by Gram-positive bacteria in adults receiving outpatient parenteral antimicrobial therapy (OPAT), administered by Hospital at Home units (HaH) in Spain. Material and method: Observational, multicenter, retrospective study. We included patients of both sexes included in the HaH-based OPAT Registry during 2011 to 2017 who were hospitalized due to SSSIs caused by Gram-positive bacteria. Resource use included home visits (nurses and physician), emergency room visits, conventional hospitalization stay, HaH stay and antibiotic treatment. Costs were quantified by multiplying the natural units of the resources by the corresponding unit cost. All costs were updated to 2019 euros. Results: We included 194 episodes in 189 patients from 24 Spanish hospitals. The most frequent main diagnoses were cellulitis (26.8%) and surgical wound infection (24.2%), and 94% of episodes resulted in clinical improvement or cure after treatment. The median HaH stay was 13 days (interquartile range [IR]:8-22.7), and the conventional hospitalization stay was 5 days (IR: 1-10.7). The mean total cost attributable to the complete infectious process was €7,326 (95% confidence interval: €6,316-€8,416). Conclusions: Our results suggest that OPAT administered by HaH is a safe and efficient alternative for the management of these infections and could lead to lower costs compared with hospital admission.

Objetivo: Describir y cuantificar el uso de recursos y costes directos sanitarios asociados con las infecciones de piel y tejidos blandos (IPPB) causadas por microorganismos grampositivos en adultos que recibieron tratamiento antimicrobiano domiciliario endovenoso (TADE), administrado en unidades de hospitalización a domicilio (HaD) en España. Material y métodos: Estudio observacional, multicéntrico, retrospectivo. Se incluyeron pacientes adultos de ambos sexos, incluidos en el Registro TADE en el periodo 2011 a 2017y cuyo motivo de ingreso fue una IPPB causada por un microorganismo Grampositivo. El uso de recursos incluyó las visitas a domicilio (enfermería y médico), visitas a urgencias, estancia en hospitalización convencional, estancia en HaD y tratamiento antibiótico. Los costes se cuantificaron multiplicando las unidades naturales de los recursos por el coste unitario correspondiente. Todos los costes fueron actualizados a euros de 2019. Resultados: Se incluyeron 194 episodios (189 pacientes) procedentes de 24 centros españoles. Los diagnósticos principales más frecuentes fueron celulitis (26,8%) e infección por herida quirúrgica (24,2%). El 94% de los episodios resultaron en una mejoría o curación clínica al finalizar el tratamiento. La mediana de la estancia en HaD fue de 13 días (rango intercuartílico [RI]:8-22,7), con una estancia previa en hospitalización convencional de 5 días (RI: 1-10,7). El coste total promedio atribuible al proceso infecciosos completo fue de 7.326€ (intervalo de confianza del 95%: 6.316€-8.416€). Conclusiones: Este estudio sugiere que el TADE administrado en HaD es una alternativa segura y eficiente para el manejo de estas infecciones y podría conducir a menores costes en comparación con el ingreso hospitalario.

Outpatient parenteral antimicrobial therapy (OPAT) programmes make it possible to start or complete intravenous antimicrobial therapy for practically any type of infection at home, provided that patient selection is appropriate for the type of OPAT programme available. Although the clinical management of infections in the home setting is comparable in many respects to that offered in conventional hospitalization (selection of antibiotics, duration of treatment, etc.), there are many aspects that are specific to this care modality. It is essential to be aware of them so that OPAT continues to be as safe and effective as inpatient care. The objective of this clinical guideline is therefore to provide evidence- and expert-based recommendations with a view to standardizing clinical practice in this care modality and contribute to a progressive increase in the number of patients who can be cared for and receive intravenous therapy in their own homes

Los programas de tratamiento antibiótico domiciliario endovenoso (TADE) permiten iniciar o completar el tratamiento antimicrobiano por vía endovenosa de prácticamente cualquier tipo de infección en el domicilio, siempre y cuando se realice una selección del paciente acorde al tipo de programa de TADE que se dispone. Aunque hay aspectos del manejo clínico de las infecciones en el domicilio que son superponibles en la mayoría de los casos a la realizada en la hospitalización convencional (selección de la antibioterapia, duración del tratamiento, etc.), existen numerosos aspectos que son específicos de esta modalidad asistencial. Resulta imprescindible conocerlos para que el TADE siga siendo igual de eficaz y seguro que la hospitalización convencional. El objetivo de esta guía clínica es por tanto, proporcionar recomendaciones basadas en la evidencia realizadas por expertos para homogeneizar la práctica clínica de esta modalidad asistencial y contribuir a que se incremente progresivamente el número de pacientes que pueden ser atendidos y recibir tratamiento endovenoso en su propio domicilio

Usefulness of Hospital at Home in nosocomial infections: advantages and limitations / Utilidad de la Hospitalización a Domicilio en las infecciones nosocomiales: ventajas y limitaciones

Hospital at Home units allows ambulatory treatment and monitoring of complex and serious infections. Nosocomial infections produce an extension of the stay in hospital often specifying long intravenous treatments without any effective oral alternatives. Daily dosing of antimicrobial are easier to administer at home. The use of portable programmable pump infusion and elastomeric devices allow efficient and safe infusions for most antimicrobials at home. Some antibiotics against multidrug-resistant organisms of recent introduction have a suitable profile for outpatient intravenous treatment (AU)

Las unidades de Hospitalización a Domicilio permiten el tratamiento y control ambulatorio de infecciones graves y complejas. Las infecciones nosocomiales suponen una prolongación de la estancia hospitalaria precisando con frecuencia largos tratamientos intravenosos sin alternativa eficaz oral. Los antimicrobianos más sencillos de administrar en domicilio son aquellos con dosis única diaria. La utilización de bombas programables portátiles de infusión y de dispositivos elastoméricos permite infundir con eficacia y seguridad la mayoría de antimicrobianos. Algunos de los antibióticos frente a microorganismos multirresistentes de reciente introducción tienen un perfil muy adecuado para el tratamiento intravenoso ambulatorio (AU)

Daptomycin for the treatment of infective endocarditis: results from a European registry.

OBJECTIVES: Infective endocarditis (IE) is a complex infection associated with high mortality. Daptomycin, a cyclic lipopeptide antibiotic highly active against Gram-positive bacteria, has recently been incorporated into IE treatment guidelines. This retrospective analysis provides insights into the use of daptomycin in IE in the European Cubicin(®) Outcomes Registry Experience (EU-CORE(SM)) between 2006 and 2010. PATIENTS AND METHODS: Three hundred and seventy-eight (10%) of 3621 enrolled patients received daptomycin for treatment of IE. Two hundred and fifty-nine (69%) had left-sided IE (LIE) and 182 patients (48%) underwent concomitant surgery. RESULTS: Staphylococcus aureus was the most frequently identified pathogen (n=92; methicillin susceptible, n=50) and daptomycin was used empirically in 134 patients. Among cases of second-line therapy (n=312), the most common reason for switching to daptomycin was failure of the previous regimen (including glycopeptides and penicillins). Daptomycin was administered at 6 mg/kg in 224 patients and at ≥ 8 mg/kg in 72 patients. Clinical success rates were 80% overall, 91% for right-sided IE (RIE) and 76% for LIE, with similar rates seen for infections caused by methicillin-susceptible S. aureus (84%) and methicillin-resistant S. aureus (81%). The clinical success rate in patients treated with ≥ 8 mg/kg daptomycin was 90% [n=72 (RIE, 91%; LIE, 89%)]. No new safety signals were observed. CONCLUSIONS: In patients with IE registered in EU-CORE, daptomycin was most frequently used as second-line treatment after treatment failure. The majority of patients had LIE and most commonly received daptomycin for the treatment of staphylococcal infections. Clinical success was high in this difficult-to-treat population. The role of doses ≥ 8 mg/kg per day in the empirical treatment of IE deserves further investigation.

Daptomicina en el paciente con hospitalización a domicilio / Daptomycin in home hospitalization

El tratamiento antimicrobiano parenteral ambulatorio (OPAT [outpatient parenteral antimicrobial therapy]) es un procedimiento muy extendido en Estados Unidos, que comporta ventajas tanto para el paciente como para los hospitales. En los últimos años, varios países europeos, como Reino Unido o Italia, han empezado a mostrar interés por OPAT, desarrollándolo a través de diferentes estructuras asistenciales. En España, son las unidades de hospitalización a domicilio el recurso más utilizado. La introducción de daptomicina, un antibiótico de administración única diaria, que permite su infusión rápida y que no precisa la monitorización de sus valores plasmáticos, facilita enormemente la ambulatorización del tratamiento de infecciones graves por microorganismos grampositivos. Los resultados de ensayos clínicos, de series de casos y de registros poscomercialización apoyan la eficacia y seguridad del uso de daptomicina en OPAT (AU)

Outpatient Parenteral Antimicrobial Therapy (OPAT) is widely used in the United States and has advantages for both patients and hospitals. In the last few years, several European countries such as the United Kingdom and Italy have begun to show interest in OPAT, developing this therapeutic modality through distinct healthcare structures. In Spain, the most widely used resources are hospital at home units. Daptomycin is an antibiotic that is administered in a single daily dose, which allows its rapid infusion, and does not require monitoring of plasma levels. These two factors greatly facilitate the ambulatory treatment of severe infections due to Gram-positive microorganisms. The results of clinical trials, case series and post-commercialization registries support the safety and efficacy of the use of daptomycin in OPAT (AU)
