Infection control in long term care institutions for the elderly: A reflection document on the situation in Spain

A progressively increasing percentage of the elderly live during the last years of their lives in nursing homes. Although these institutions are intended to mimic life at home as much as possible, they have characteristics that make them quite similar to a “nosocomiun”, i.e. an establishment for the treatment of the sick. The very coexistence among the elderly, the fact of sharing caregivers and the very significant exposure to third parties, together with the frequent predisposing diseases to infection in this population, make infection frequent among residents and also easily transmissible. This leads us to ask what can be done to prevent infection in this environment and more specifically what is the state of the art of the matter in a Western European nation such as ours. The Board of Trustees of the Health Sciences Foundation has asked itself a series of questions on the subject of infection prevention in Nursing Homes, the structure of procedures, the legislation available, compliance with the measures indicated, the best indicators of the processes and therefore, the need to promote in Spain a document of recommendations to avoid infections in this poplation whose morbidity and mortality need not be highlighted. To this end, a multidisciplinary group of experts in different aspects of this problem has been convened and asked the proposed questions. The questions were discussed by the group as a whole and led to a series of conclusions agreed upon by the participants. The results of the meeting are reported below (AU)

Un porcentaje progresivamente creciente de las personas mayores viven durante los últimos años de su vida en residencias de ancianos. Dichas instituciones, aunque pretenden remedar lo más posible la vida en el hogar, tienen características que las hace bastante parecidas a un nosocomio, es decir a un establecimiento destinado al tratamiento de enfermos. La propia convivencia entre los ancianos, el hecho de compartir cuidadores y la exposición muy importante a terceras personas, junto con las frecuentes enfermedades predisponentes a la infección de esta población, hacen que la infección sea frecuente entre los residentes y que además sea fácilmente transmisible. Esto nos lleva a preguntarnos qué puede hacerse para prevenir la infección en este medio y más concretamente cuál es el estado del arte de la cuestión en una nación de Europa Occidental como la nuestra. El patronato de la Fundación de Ciencias de la Salud se ha formulado una serie de preguntas sobre el tema de la prevención de la infección en las Residencias de Mayores, la estructura de la misma, la legislación vigente, el cumplimiento de las medidas indicadas, los indicadores de los procesos y por ende, la necesidad de fomentar en España un documento de recomendaciones para evitar infecciones en esta población cuya morbilidad y mortalidad no necesitan ser resaltadas. Para ello, se ha convocado a un grupo multidisciplinar de expertos en distintos aspectos de este problema a los que se les han formulado las preguntas propuestas. Las preguntas han sido discutidas por el grupo en su conjunto y han conducido a una serie de conclusiones consensuadas entre los participantes. Pasamos, a continuación a relatar los resultados de la reunión (AU)

Clinical and Ecological Impact of an Educational Program to Optimize Antibiotic Treatments in Nursing Homes (PROA-SENIOR): A Cluster, Randomized, Controlled Trial and Interrupted Time-Series Analysis.

BACKGROUND: Antimicrobial stewardship programs (ASPs) are recommended in nursing homes (NHs), although data are limited. We aimed to determine the clinical and ecological impact of an ASP for NHs. METHODS: We performed a cluster, randomized, controlled trial and a before-after study with interrupted time-series analyses in 14 NHs for 30 consecutive months from July 2018 to December 2020 in Andalusia, Spain. Seven facilities implemented an ASP with a bundle of 5 educational measures (general ASP) and 7 added 1-to-1 educational interviews (experimental ASP). The primary outcome was the overall use of antimicrobials, calculated monthly as defined daily doses (DDD) per 1000 resident days (DRD). RESULTS: The total mean antimicrobial consumption decreased by 31.2% (-16.72 DRD; P = .045) with respect to the preintervention period; the overall use of quinolones and amoxicillin-clavulanic acid dropped by 52.2% (P = .001) and 42.5% (P = .006), respectively; and the overall prevalence of multidrug-resistant organisms (MDROs) decreased from 24.7% to 17.4% (P = .012). During the intervention period, 12.5 educational interviews per doctor were performed in the experimental ASP group; no differences were found in the total mean antimicrobial use between groups (-14.62 DRD; P = .25). Two unexpected coronavirus disease 2019 waves affected the centers increasing the overall mean use of antimicrobials by 40% (51.56 DRD; P < .0001). CONCLUSIONS: This study suggests that an ASP for NHs appears to be associated with a decrease in total consumption of antimicrobials and prevalence of MDROs. This trial did not find benefits associated with educational interviews, probably due to the coronavirus disease 2019 pandemic. Clinical Trials Registration. NCT03543605.
