Seguimiento Funcional hasta Seis Meses después de Sobrevivir a Cuidados Intensivos: Lecciones aprendidas de un Estudio Chileno Multicéntrico / Functional follow-up six months after surviving intensive care: lessons learned from a Chilean multicenter study

Introducción. Las tasas de retención en los estudios de seguimiento oscilan entre el 32 y 100%, demostrando el desafío que implica realizar estudios longitudinales de sobrevivientes de la unidad de cuidados intensivos (UCI). Objetivo. Identificar las estrategias implementadas y lecciones aprendidas en un estudio prospectivo multicéntrico de seguimiento de sobrevivientes de la UCI durante la pandemia. Métodos. Estudio post-hoc de las lecciones aprendidas mediante encuestas y entrevistas dirigidas a explorar la experiencia de los investigadores y coordinadores del estudio IMPACCT COVID-19, realizado en siete centros chilenos entre octubre 2020 y abril 2021 evaluando el síndrome post-cuidados intensivos de sobrevivientes hasta seis meses después. Resultados. Identificamos ocho lecciones: 1) selección de instrumentos de medición, 2) identificación de centros participantes, 3) aprobación del estudio, 4) financiamiento, 5) capacitación de evaluadores, 6) coordinación/aseguramiento de calidad, 7) reclutamiento y 8) seguimiento de pacientes. Incluso durante el primer año de pandemia, reclutamos 252 pacientes a una tasa de 1,4 pacientes/día con una retención del 48% a los 6 meses de seguimiento. El uso de redes académicas existentes y las estrategias de comunicación entre investigadores, coordinadores y evaluadores fueron aspectos positivos; mientras que la fidelización con evaluadores al egreso de la UCI y con pacientes durante el seguimiento son aspectos que deberían considerarse en futuros estudios. Conclusiones. Se evaluaron más de 250 pacientes en seis meses durante la pandemia, con tasas de retención post UCI acorde a la literatura. Futuros estudios debiesen optimizar los procesos de medición y de seguimiento para minimizar la pérdida de pacientes.

Background. Retention rates of follow-up studies range from 32 to 100%, demonstrating the challenge to conduct longitudinal studies of intensive care unit (ICU) survivors. Objective. To identify the strategies implemented and lessons learned in a multicenter prospective follow-up study of ICU survivors during pandemic times. Methods. Post-hoc study of lessons learned through surveys and interviews aimed at exploring the experience of the researchers and coordinators of the IMPACCT COVID-19 study. The original study was performed in seven Chilean sites between October 2020 and April 2021 evaluating the post-intensive care syndrome of survivors up to six-month follow-up. Results. We identified eight lessons: 1) selection of measurement instruments, 2) identification of participating sites, 3) Study approval, 4) funding, 5) evaluators training, 6) coordination/quality assurance, 7) recruitment, and 8) patient follow-up. Even during the first year of the pandemic, we recruited 252 patients at a rate of 1.4 patients/day with a retention rate of 48% at 6 months of follow-up. The use of existing academic networks and communication strategies between researchers, coordinators and evaluators were positive aspects; while evaluators fidelity at ICU discharge and patient engagement during follow-up are aspects should be considered. Conclusions. More than 250 patients were evaluated in six months during the pandemic, with post-ICU retention rates consistent with the literature. Future studies should optimize measurement and monitoring processes to minimize patient atrition.

Impact on Mental, Physical and Cognitive functioning of a Critical care sTay during the COVID-19 pandemic (IMPACCT COVID-19): protocol for a prospective, multicentre, mixed-methods cohort study.

INTRODUCTION: The ongoing pandemic could affect the duration, variety and severity of the mental, physical, and cognitive impairments intensive care unit (ICU) survivors and their families frequently present. We aim to determine the impact of the COVID-19 pandemic on the mental, physical, and cognitive health of survivors, the experience of their families and their treating healthcare professionals. METHODS AND ANALYSIS: Prospective, multicentre, mixed-methods cohort study in seven Chilean ICUs. SAMPLE: 450 adults, able to walk independently prior to admission, in ICU and mechanical ventilation >48 hours with and without COVID-19. Clinical Frailty Scale, Charlson comorbidity index, mobility (Functional Status Score for the Status Score for the Intensive Care Unit) and muscle strength (Medical Research Council Sum Score) will be assessed at ICU discharge. Cognitive functioning (Montreal Cognitive Assessment-blind), anxiety and depression (Hospital Anxiety and Depression Scale), post-traumatic stress (Impact of Event Scale-Revised) symptoms, disability (WHO Disability Assessment Schedule 2.0), quality of life (European Quality of Life Health Questionnaire), employment and survival will be assessed at ICU discharge, 3 months and 6 months. A sample will be assessed using actigraphy and the Global Physical Activity Questionnaire at 6 months after ICU discharge. Trajectories of mental, physical, and cognitive impairments will be estimated using multilevel longitudinal modelling. A sensitivity analysis using multiple imputations will be performed to account for missing data and loss-to-follow-up. Survival will be analysed using Kaplan-Meier curves. The perceptions of family members regarding the ICU stay and the later recovery will be explored 3 months after discharge. Healthcare professionals will be invited to discuss the challenges faced during the pandemic using semistructured interviews. Interviews will be thematically analysed by two independent coders to identify the main themes of the experience of family members and healthcare professionals. ETHICS AND DISSEMINATION: The study was approved by the Clinica Alemana Universidad del Desarrollo Ethics Committee (2020-78) and each participating site. Study findings will be published in peer-reviewed journals and disseminated through social media and conference meetings. TRIAL REGISTRATION NUMBER: NCT04979897.

Construct Validity of the Chilean-Spanish Version of the Functional Status Score for the Intensive Care Unit: A Prospective Observational Study Using Actigraphy in Mechanically Ventilated Patients.

OBJECTIVE: To evaluate the construct validity (hypotheses testing) of the Chilean-Spanish version of the Functional Status Score for the Intensive Care Unit (FSS-ICU) using continuous actigraphy from intensive care unit (ICU) admission to ICU discharge. DESIGN: The Chilean-Spanish version of the FSS-ICU was used in a prospective observational study to mainly evaluate its correlation with actigraphy variables. The FSS-ICU was assessed on awakening and at ICU discharge, while actigraphy variables were recorded from ICU admission to ICU discharge. SETTING: A 12-bed academic medical-surgical ICU. PARTICIPANTS: Mechanically ventilated patients (N=30), of 92 patients screened. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Construct validity of the FSS-ICU Chilean-Spanish version was assessed by testing 12 hypotheses, including the correlation with activity counts, activity time (>99 counts/min), inactivity time (0-99 counts/min), muscle strength, ICU length of stay, and duration of mechanical ventilation. RESULTS: The median FSS-ICU was 19 points (interquartile range [IQR], 10-26 points) on awakening and 28.5 points (IQR, 22-32 points) at ICU discharge. There was no floor/ceiling effect of the FSS-ICU at awakening (0%/0%) and only a ceiling effect at ICU discharge that was acceptable (0%/10%). Less activity time was associated with better mobility on the FSS-ICU at both awakening (ρ=-0.62, P<.001) and ICU discharge (ρ=-0.79, P<.001). Activity counts and activity time were not correlated as expected with the FSS-ICU. CONCLUSIONS: The Chilean-Spanish FSS-ICU had a strong correlation with inactivity time during the ICU stay. These findings enhance the available clinimetric properties of the FSS-ICU.

Characteristics of physiotherapy staffing levels and caseload: a cross-sectional survey of Chilean adult Intensive Care Units.

INTRODUCTION: The European Society of Intensive Care Medicine recommends the presence of a specialist physiotherapist, available every five beds, seven days a week in the high complexity Intensive Care Unit. However, in Chile the adherence of adult Intensive Care Units to this recommendation is unknown. OBJECTIVE: To describe the organizational characteristics and the physiotherapist availability in adult Intensive Care Units in Chile, and according to the adherence to international recommendations, inform health decision-makers. METHODS: Observational study based on a telephone survey. All adult Intensive Care Units institutions of high complexity, private hospitals and teaching health centers in Chile were eligible (n = 74). The primary outcome measures were the proportion of institutions with physiotherapist availability 24 hours a day and seven days a week (24/7 physiotherapist), a maximum caseload per physiotherapist of five patients and the presence of a specialist physiotherapist. RESULTS: Response rate was 86.5%, with 59% of responding units being public and 83% offering level III care. 70% of the adult Intensive Care Units in Chile have 24/7 physiotherapist (87% of the public and 46% of the private sector). 41% of the centers had a maximum caseload per physiotherapist of five patients during the day on weekdays. This number decreased on weekends and during night shifts. 23% of the Intensive Care Units had a specialist physiotherapist, being more common in the private sector (31%). CONCLUSIONS: In Chilean adult ICU, 24/7 physiotherapist availability is high, the prevalence of physiotherapists with specialist training is low. Future efforts should focus on promoting the uptake of specialist training.

INTRODUCCIÓN: La Sociedad Europea de Medicina de Cuidados Intensivos recomienda la presencia de un Kinesiólogo con formación especializada, disponible cada cinco camas de alta complejidad, los 7 días de la semana en la Unidad de Cuidados Intensivos (UCI). En Chile se desconoce la adherencia de las UCI adulto a esta recomendación. OBJETIVO: Describir las características administrativas y de cobertura kinésica en las UCI adulto chilenas, y de acuerdo con la adherencia a las recomendaciones internacionales, informar a los tomadores de decisión en salud. MÉTODOS: Estudio observacional transversal, basado en encuesta telefónica. Se incluyeron las UCI adultos de establecimientos de mayor complejidad, clínicas privadas y centros asociados a universidades (n = 74). La proporción de instituciones con disponibilidad de kinesiólogos las 24 horas del día, los siete días de la semana (kinesiólogo 24/7), con un número máximo de cinco pacientes por kinesiólogo y presencia de un kinesiólogo especialista fueron reportados. RESULTADOS: La tasa de respuesta fue del 86,5% (n = 64), principalmente públicas (59%) y de nivel III (83%). El 70% (n = 45) de las UCI adulto chilenas cuentan con kinesiólogo 24/7; correspondiendo el 87% al sector público y el 46% al privado. El 41% de los centros posee un máximo de 5 pacientes por kinesiólogo en día hábil diurno, disminuyendo en fines de semana y horarios nocturnos. Un 23% de las UCIs cuenta con kinesiólogo especialista en intensivo, siendo mayor en el sector privado (31%). CONCLUSIONES: En UCI adulto chilenas, la disponibilidad de kinesiólogos 24/7 es alta, y la prevalencia de especialistas es baja. Estrategias de creación de programas de formación de especialidad podrían contribuir a disminuir la brecha de especialistas.

Effect of Early Rehabilitation during Intensive Care Unit Stay on Functional Status: Systematic Review and Meta-Analysis.

BACKGROUND AND AIM: Critically ill survivors may have functional impairments even five years after hospital discharge. To date there are four systematic reviews suggesting a beneficial impact for mobilisation in mechanically ventilated and intensive care unit (ICU) patients, however there is limited information about the influence of timing, frequency and duration of sessions. Earlier mobilisation during ICU stay may lead to greater benefits. This study aims to determine the effect of early rehabilitation for functional status in ICU/high-dependency unit (HDU) patients. DESIGN: Systematic review and meta-analysis. MEDLINE, EMBASE, CINALH, PEDro, Cochrane Library, AMED, ISI web of science, Scielo, LILACS and several clinical trial registries were searched for randomised and non-randomised clinical trials of rehabilitation compared to usual care in adult patients admitted to an ICU/HDU. Results were screened by two independent reviewers. Primary outcome was functional status. Secondary outcomes were walking ability, muscle strength, quality of life, and healthcare utilisation. Data extraction and methodological quality assessment using the PEDro scale was performed by primary reviewer and checked by two other reviewers. The authors of relevant studies were contacted to obtain missing data. RESULTS: 5733 records were screened. Seven articles were included in the narrative synthesis and six in the meta-analysis. Early rehabilitation had no significant effect on functional status, muscle strength, quality of life, or healthcare utilisation. However, early rehabilitation led to significantly more patients walking without assistance at hospital discharge (risk ratio 1.42; 95% CI 1.17-1.72). There was a non-significant effect favouring intervention for walking distance and incidence of ICU-acquired weakness. CONCLUSIONS: Early rehabilitation during ICU stay was not associated with improvements in functional status, muscle strength, quality of life or healthcare utilisation outcomes, although it seems to improve walking ability compared to usual care. Results from ongoing studies may provide more data on the potential benefits of early rehabilitation in critically ill patients.
