Interevaluator reliability of a tool for measuring body height in adult intensive care patients.

BACKGROUND: The calculation of body height in the intensive care unit is essential for obtaining the ideal body weight, which is used to program the tidal volume and establish objective and effective pulmonary ventilation. The objective of the study was to determine the interrater reliability of a tool for measuring body height in adult patients in an intensive care unit (ICU) in southwestern Colombia. METHODS: This cross-sectional observational study was conducted between January and May 2021, following the recommendations of the COSMIN protocol. Two physiotherapists in the roles of observer/evaluator measured the heights of 106 patients upon admission to the ICU with a previously designed. The sample size was calculated based on Pearson's correlation coefficient. For interrater reliability, the intraclass correlation coefficient (ICC) was used, and Bland-Altman analysis was used to assess concordance. The 95% confidence interval was established, and a P value <0.05 indicated statistical significance. RESULTS: A total of 106 individuals with a mean age of 59.3 years were included; the mean body height was 158.5 cm for women. The interrater reliability of the measurement of height was excellent (global ICC of 0.99, P = 0.000), and an almost perfect positive correlation was obtained between the raters for both women and men (R = 0.99). CONCLUSIONS: Excellent interrater/interobserver reliability was obtained for the measurement of body height in the ICU. This research highlights the importance of protocolizing the measurement of height in critical patients with valid and reliable instruments.

Evolución de la funcionalidad y la fuerza muscular desde cuidado intensivo a hospitalización en sobrevivientes por COVID-19 / Evolution of functionality and muscle strength from intensive care to hospitalization in survivors of COVID-19

Introducción El paciente crítico hospitalizado en cuidado intensivo (UCI) tiene más riesgo de deterioro en la función física. Una forma de contrarrestarlo está relacionada con la intervención temprana de fisioterapia, pero son escasos los reportes en pacientes con enfermedad severa por COVID-19. Objetivo Describir el compromiso y cambio en la funcionalidad y en la fuerza muscular en pacientes con COVID-19 que recibieron intervención temprana de fisioterapia en UCI hasta el alta hospitalaria, y comparar la evolución de acuerdo con si recibieron ventilación mecánica invasiva o no. Metodología Estudio retrospectivo de pacientes con COVID-19 que ingresaron a UCI entre marzo y septiembre del 2020 y recibieron intervención de fisioterapia. La funcionalidad se evaluó con el índice Barthel (IB) y la fuerza muscular con el Medical Research Council Sum Score (MRC-SS), los cuales fueron medidos por el fisioterapeuta de turno en dos momentos, al egreso de UCI y de hospitalización. Se consideró el valor p < 0,05 como significativo. Resultados Se revisaron 66 registros; la edad promedio fue de 53,3 (32 ± 11,5) años; 32 (48,5%) requirieron ventilación mecánica. Se observó compromiso en la funcionalidad y en la fuerza muscular, con mejoría progresiva antes del egreso hospitalario: IB [64,1 (± 34,7) vs. 87,7 (± 18,4) p = 0,000], MRC-SS [40,5 (± 11) vs. 48 (± 9) p = 0,000]. El grupo de pacientes ventilados presentó mayor compromiso IB [34,2 (± 24,7) vs. 76,7 (± 21,2) p = 0,000] y MRC-SS [31,5 (± 7,2) vs. 42,3 (± 8,3) p = 0,000]. Los días de ventilación mecánica, de relajación, y mayor APACHE II mostraron una correlación negativa significativa con las variables de resultado (p = 0,000). Conclusiones Los pacientes con enfermedad severa por COVID-19 que recibieron intervención de fisioterapia mostraron cambios significativos en la funcionalidad y en la fuerza muscular. Los pacientes que requirieron ventilación mecánica presentaron mayor compromiso funcional (AU)

Introduction The critically ill patient hospitalized in intensive care unit (ICU), has a higher risk of deterioration in physical function. One way to counteract its related to early physiotherapy intervention, but there are few reports in patients with severe disease from COVID-19. Objective To describe the compromise and change in functionality and muscle strength in patients with COVID-19 who received early physiotherapy intervention in ICU until hospital discharge and compare the evolution according to whether or not they received invasive mechanical ventilation. Methodology Retrospective study of patients with COVID-19 admitted to the ICU between March and September 2020 and received physiotherapy intervention. Functionality was assessed with the Barthel Index (BI) and muscle strength with the Medical Research Council Sum Score (MRC-SS), which were measured by the physiotherapist at two moments, upon discharge from ICU and from hospitalization. For the correlations, a value P<.05 was considered significant. Results Sixty-six records were reviewed; the mean age was 53.3 (32±11.5) years; 32 (48.5%) required mechanical ventilation. Compromise in functionality and muscle strength was observed, with progressive improvement before hospital discharge: IB [64.1 (± 34.7) vs. 87.7 (± 18.4), P = .000], MRC-SS [40.5 (± 11) vs. 48 (± 9), P = .000]. The group of ventilated patients presented greater compromise: IB [34.2 (± 24.7) vs. 76.7 (± 21.2), P = .000] and MRC-SS [31.5 (± 7.2) vs. 42.3 (± 8.3), P = .000]. The days of mechanical ventilation, relaxation, and higher APACHE II showed a significant negative correlation with the outcome variables (P = .000). Conclusions Patients with severe disease from COVID-19 who received physiotherapy intervention, showed significant changes in functionality and muscle strength. The patients who required mechanical ventilation presented greater functional compromise (AU)

Confiabilidad interevaluador de la medición de la excursión diafragmática y fracción de engrosamiento diafragmático mediante ultrasonografía en voluntarios sanos / Inter-rater reliability of the measurement of diaphragmatic excursion and fraction of diaphragmatic thickening by ultrasonography in healthy volunteers

Antecedentes y objetivo: Determinar la confiabilidad interevaluador en la medición ultrasonográfica (US) de la excursión diafragmática (ED) y la fracción de engrosamiento diafragmático (FED) realizada por profesionales de salud no médicos en voluntarios sanos. Participantes y métodos: Estudio observacional prospectivo en un hospital de tercer nivel en Cali, Colombia. Se realizaron mediciones a 30 voluntarios sanos escogidos mediante muestreo a conveniencia, sin antecedentes de enfermedades pulmonares, con edades entre los 18-60 años. Previamente se realizó una prueba piloto con 8 voluntarios sanos. Las mediciones US de ED y FED se basaron en protocolos publicados anteriormente. Cada evaluador observaba independientemente varios ciclos de respiración tranquila normal durante 3minutos para establecer una línea de base. Para evaluar la confiabilidad interevaluador en las mediciones de ED y FED se utilizó el índice de correlación intraclase (ICC), con intervalos de confianza del 95% y un p<0,05. Resultados: Se identificó concordancia sustancial en la medición de la ED en las ventanas esplénica y hepática debido a que el ICC fue mayor a 0,6 (p<0,05). La medición de la FED en la ventana hepática mostró concordancia leve tanto en el modo 2D como en el modo M (p>0,05). En la ventana esplénica la medición de la FED en el modo 2D se identificó concordancia regular y para el modo M se encontró una concordancia leve (p>0,05). Conclusiones: La US diafragmática constituye un método reproducible con aceptable confiabilidad interevaluador para la medición del grosor inspiratorio/espiratorio y con confiabilidad pobre para la medición de FED.(AU)

Background and objective: To determine the inter-rater reliability in the ultrasonographic (US) measurement of the diaphragmatic excursion (DE) and the diaphragm thickness fraction (DTF) performed by non-medical health professionals in healthy people. Participants and methods: Prospective observational study in a third level hospital in Cali, Colombia. Measurements were made to 30 healthy volunteers chosen by convenience sampling, without a history of lung diseases, with ages between 18-60 years. A pilot test was previously carried out with 8 healthy volunteers. US measurements of DE, and DTF were based on previously published protocols. Each assessor independently observed several cycles of normal quiet breathing for 3minutes to establish a baseline. The Intraclass Correlation Index (ICC) was used to evaluate the inter-rater reliability in the measurements of DE and DTF, with 95% confidence intervals and a P<.05. Results: Substantial agreement was identified in the measurement of DE in the splenic and hepatic windows because the ICC was greater than 0.6 (P<.05). The measurement of the DTF in the hepatic window showed slight agreement in both 2D and M modes (P>.05). In the splenic window, the measurement of the DTF in the 2D mode was found to be moderate agreement and for the M mode a slight agreement was found (P>.05).Conclusions: The diaphragmatic US constitutes a reproducible method with acceptable inter-rater reliability for the measurement of inspiratory/expiratory thickness, and with little reliability for the measurement of DTF.(AU)

Efficacy of respiratory muscle training in weaning of mechanical ventilation in patients with mechanical ventilation for 48hours or more: A Randomized Controlled Clinical Trial. / Eficacia del entrenamiento muscular respiratorio en el destete de la ventilación mecánica en pacientes con ventilación mecánica por 48 o más horas: un ensayo clínico controlado.

OBJECTIVE: To evaluate the efficacy of respiratory muscular training in the weaning of mechanical ventilation and respiratory muscle strength in patients on mechanical ventilation of 48hours or more. DESIGN: Randomized controlled trial of parallel groups, double-blind. Ambit: Intensive Care Unit of a IV level clinic in the city of Cali. PATIENTS: 126 patients in mechanical ventilation for 48hours or more. INTERVENTIONS: The experimental group received daily a respiratory muscle training program with treshold, adjusted to 50% of maximal inspiratory pressure, additional to standard care, conventional received standard care of respiratory physiotherapy. MAIN INTEREST VARIABLES: weaning of mechanical ventilation. Other variables evaluated: respiratory muscle strength, requirement of non-invasive mechanical ventilation and frequency of reintubation. ANALYSIS: intention-to-treat analysis was performed with all variables evaluated and analysis stratified by sepsis condition. RESULTS: There were no statistically significant differences in the median weaning time of the MV between the groups or in the probability of extubation between groups (HR: 0.82 95% CI: 0.55-1.20 P=.29). The maximum inspiratory pressure was increased in the experimental group on average 9.43 (17.48) cmsH20 and in the conventional 5.92 (11.90) cmsH20 (P=.48). The difference between the means of change in maximal inspiratory pressure was 0.46 (P=.83 95%CI -3.85 to -4.78). CONCLUSIONS: respiratory muscle training did not demonstrate efficacy in the reduction of the weaning period of mechanical ventilation nor in the increase of respiratory muscle strength in the study population.
