[Liaison geriatrics with nursing homes in COVID time. A new coordination model arrived to stay]. / La Geriatría de Enlace con residencias en la época de la COVID-19. Un nuevo modelo de coordinación que ha llegado para quedarse.

Older people living in nursing homes fulfil the criteria to be considered as geriatric patients, but they often do not have met their health care needs. Current deficits appeared as a result of COVID-19 pandemic. The need to improve the coordination between hospitals and nursing homes emerged, and in Madrid it materialized with the implantation of Liaison Geriatrics teams or units at public hospitals. The Sociedad Española de Geriatría y Gerontología has defined the role of the geriatricians in the COVID-19 pandemic and they have given guidelines about prevention, early detection, isolation and sectorization, training, care homes classification, patient referral coordination, and the role of the different care settings, among others. These units and teams also must undertake other care activities that have a shortfall currently, like nursing homes-hospital coordination, geriatricians visits to the homes, telemedicine sessions, geriatric assessment in emergency rooms, and primary care and public health services coordination. This paper describes the concept of Liaison Geriatrics and its implementation at the Autonomous Community of Madrid hospitals as a result of COVID-19 pandemic. Activity data from a unit at a hospital with a huge number of nursing homes in its catchment area are reported. The objective is to understand the need of this activity in order to avoid the current fragmentation of care between hospitals and nursing homes. This activity should be consolidated in the future.

Application of ultrasound for muscle assessment in sarcopenia: 2020 SARCUS update.

PURPOSE: In 2018, the SARCUS working group published a first article on the standardization of the use of ultrasound to assess muscle. Recommendations were made for patient positioning, system settings and components to be measured. Also, shortcomings in knowledge were mentioned. An important issue that still required standardization was the definition of anatomical landmarks for many muscles. METHODS: A systematic search was performed in Medline, SCOPUS and Web of Sciences looking for all articles describing the use of ultrasound in the assessment of muscle not described in the first recommendations, published from 01/01/2018 until 31/01/2020. All relevant terms used for older people, ultrasound and muscles were used. RESULTS: For 39 muscles, different approaches for ultrasound assessment were found that likely impact the values measured. Standardized anatomical landmarks and measuring points were proposed for all muscles/muscle groups. Besides the five already known muscle parameters (muscle thickness, cross-section area, pennation angle, fascicle length and echo-intensity), four new parameters are discussed (muscle volume, stiffness, contraction potential and microcirculation). The former SARCUS article recommendations are updated with this new information that includes new muscle groups. CONCLUSIONS: The emerging field of ultrasound assessment of muscle mass only highlights the need for a standardization of measurement technique. In this article, guidelines are updated and broadened to provide standardization instructions for a large number of muscles.
