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.

Feasibility of a Hospital-at-Home Program for Autologous Hematopoietic Stem Cell Transplantation.

The Hospital at Home (HaH) model has been positioned as an appropriate therapeutic strategy for selected patients undergoing autologous hematopoietic stem cell transplantation (ASCT). This care model provides hospital-equivalent care, in terms of both quality and quantity, with medical and nursing staff that go to the patient's home. Here we describe our experience with a full HaH model for patients undergoing ASCT during the phase of aplasia. The patients met the eligibility criteria between January 1997 and December 2019 and were discharged from the hospital and admitted into the HaH-ASCT program on the same day they in which hematopoietic stem cells were infused. A total of 84 patients were included. The median patient age was 54 years (range, 16 to 74 years), and the median duration of participation in the HaH program was 17 days (range, 3 to 86 days). Only 10 of these patients (12%) required hospital readmission to the hematology department, 9 of them due to sepsis and 1 because of family care support claudication. Seventy-two patients (86%) experienced an episode of neutropenic fever during the HAH admission, with a median duration of 2 days (interquartile range [IQR], 1 to 11 days); all were treated with empiric i.v. antimicrobial therapy. Most patients (88%) presented with mucositis (44% with grade 3-4). Parenteral nutrition was administered in 26% of patients for a median of 6 days (IQR, 1 to 12 days). Most patients (94%) required at least 1 blood product transfusion at home. There was no transplantation-related mortality during the HaH-ASCT program or in the patients who were readmitted. With careful selection of patients and a comprehensive and well- experienced multidisciplinary team (doctors, nurses, and auxiliary nurses) in the HaH department and in close collaboration with the hematology department, complete at-home management of ASCT recipients immediately after transplantation is possible. This allows patients undergoing an aggressive procedure such as ASCT to remain in their own familiar environment, providing a better quality of life with a program that has demonstrated to be effective and safe, with a low incidence of complications and no associated mortality.

Factores asociados a la infección por Clostridium difficile en un servicio de hospitalización domiciliaria / Factors associated to Clostridium difficile infection in a hospital-based home care service

Antecedentes y objetivo: No hay datos relativos a los factores de riesgo asociados a la infección por Clostridium difficile (ICD) en los servicios de hospitalización domiciliaria (SHD) del sistema sanitario español. Pacientes y métodos: Estudio casos-controles. Los casos fueron pacientes ingresados en un SHD entre 1 de enero de 2011 y el 31 de diciembre de 2016, que desarrollaron ICD. Los controles procedían de la misma población, con sospecha clínica de ICD y toxina CD(-). Se analizaron 82 variables. Resultados: Fueron evaluados 17 casos y 95 controles, sin diferencias por sexo, edad o comorbilidad. Se registró diarrea en el 94% y 92%, y un porcentaje de exitus del 18% y 1%, respectivamente (p=0,001). La hemiplejia/paraplejia se asoció significativamente con la ICD (odds ratio [OR] ajustada=26,4; IC 95%: 2,9-235,6; p=0,003), mientras que la enfermedad respiratoria crónica y el uso de cefalosporinas presentaron una significación marginal (OR ajustadas de 2,9 [0,8-10,3] y 3,1 [0,8-11,3], ambas p=0,08). Conclusiones: Las acciones en el SHD frente a la ICD deberían incluir una reducción en el uso de antibióticos de riesgo -según lo observado, las cefalosporinas- especialmente ante ciertas comorbilidades, como una hemiplejia/tetraplejia o una enfermedad respiratoria crónica

Background and objective: There are no data related to the risk factors associated with CDI in a Hospital-Based Home Care Service (HBHCS) of the Spanish health system. Patients and methods: Case-control study. The cases were patients admitted to the HBHCS between 01/01/2011 and 31/12/2016 who developed CDI. The controls came from the same population, with suspected CDI and CD(-) toxin. We analysed 82 variables. Results: We analysed 17 cases and 95 controls, without differences in sex, age or comorbidity. Diarrhoea was noted in 94% and 92%, and a percentage of deaths of 18% and 1%, respectively (P=.001). The presence of hemiplegia/paraplegia (adjusted odds ratio [OR]=26.4, 95% CI 2.9-235.6, P=.003) showed a significant relationship with CDI, while chronic respiratory disease and the use of cephalosporins did so with marginal significance (adjusted OR=2.9, 95% CI 0.8-10.3 and 3.1, 95% CI 0.8-11.3, respectively, both P=.08). Conclusions: Actions in the HBHCS directed towards CDI should include a reduction in the use of high-risk antibiotics -according to our results, cephalosporins- especially in patients with specific comorbidities, such as hemiplegia/tetraplegia or a chronic respiratory disease
