Purpose: To investigate the predictive validity of the Chelsea Critical Care Physical Assessment tool (CPAx) at intensive care unit (ICU) discharge in critically ill adults for their 90-day outcomes. Materials and methods: This prospective clinimetric study investigated four theory-driven, a-priori hypotheses in critically ill adults recruited within 72-144 h of mechanical ventilation. The primary hypothesis was a moderate accuracy (AUROC ¼ 0.750) in predicting residence at home within 90 days. Secondary hypotheses included discrimination between hospital discharge destinations, correlation with subsequent health-related quality of life and length of ICU stay. Results: We observed a good accuracy (AUROC ¼ 0.778) of the CPAx at ICU discharge in predicting a return to home within 90 days. The CPAx score significantly increased between the discharge groups "undesirable" � "rehabilitation" � "home" (p < 0.001), but was not associated with 90-day health-related quality of life (physical: r ¼ 0.261, mental: r ¼ 0.193). Measured at baseline, CPAx scores correlated as expected with length of ICU stay (r ¼ À 0.443). Conclusions: The CPAx at ICU discharge had a good predictive validity in projecting residence at home within 90 days and general discharge destinations. The CPAx might therefore have clinical value in prediction, though it does not seem useful to predict subsequent health-related quality of life. TRIAL REGISTRATION: German Clinical Trials Register (DRKS) identification number: DRKS00012983, registered on September 20, 2017 � IMPLICATIONS FOR REHABILITATION � The CPAx is a valid and reliable measurement instrument to evaluate critically ill adults' physical function and activity, in addition the CPAx might be useful to predict rehabilitation needs. � The CPAx had a moderate to good predictive validity with three out of four a-priori hypotheses accepted. � A CPAx score of �18 at critical care discharge has a sensitivity of 80% and a specificity of 70% in predicting a return to home within 90 days. � The CPAx might consequently be valuable to identify critically ill adults' rehabilitation needs, to advise on their potential trajectory of recovery or to screen patients for follow-up after hospital discharge.
Objective: To assess the predictive performance of Acute Physiologic and Chronic Health Evaluation II (APACHE II) software available on the hospital intranet and analyze interrater reliability of calculating the APACHE II score by the gold standard manual method or automatically using the software. Materials and Methods: An expert scorer not involved in the data collection had calculated APACHE II score of 213 patients admitted to surgical Intensive Care Unit using the gold standard manual method for a previous study performed in the department. The same data were entered into the computer software available on the hospital intranet (http://intranet/apacheii) to recalculate the APACHE II score automatically along with the predicted mortality. Receiver operating characteristic curve (ROC), Hosmer-Lemeshow goodness-of-fit statistical test and Pearson's correlation coefficient was computed. Results: The 213 patients had an average APACHE II score of 17.20 ± 8.24, the overall mortality rate was 32.8% and standardized mortality ratio was 1.00. The area under the ROC curve of 0.827 was significantly >0.5 (P < 0.01) and had confidence interval of 0.77-0.88. The goodness-of-fit test showed a good calibration (H = 5.46, P = 0.71). Interrater reliability using Pearson's product moment correlations demonstrated a strong positive relationship between the computer and the manual expert scorer (r = 0.98, P = 0.0005). Conclusion: APACHE II software available on the hospital's intranet has satisfactory calibration and discrimination and interrater reliability is good when compared with the gold standard manual method.

Purpose: To translate and cross-culturally adapt the Chelsea Critical Care Physical Assessment tool from English to German (CPAx-GE) and to examine its validity and reliability. Materials and methods: Following a forward-backward translation including an expert round table discussion, the measurement properties of the CPAx-GE were explored in critically ill, mechanically ventilated adults. We investigated construct, cross-sectional, and cross-cultural validity of the CPAx-GE with other measurement instruments at pre-specified timepoints, analysed relative reliability with intraclass correlation coefficients (ICCs) and determined absolute agreement with the Bland-Altman plots. Results: Consensus for the translated CPAx-GE was reached. Validity was excellent with >80% of the prespecified hypotheses accepted at baseline, critical care, and hospital discharge. Interrater reliability was high (ICCs > 0.8) across all visits. Limit of agreement ranged from À2 to 2 points. Error of measurement was small, floor, and ceiling effects limited. Conclusions: The CPAx-GE demonstrated excellent construct, cross-sectional, and cross-cultural validity as well as high interrater reliability in critically ill adults with prolonged mechanical ventilation at baseline, critical care, and hospital discharge. Consequently, the CPAx-GE can be assumed equal to the original and recommended in the German-speaking area to assess physical function and activity of critically ill adults across the critical care and hospital stay. Trial registration: German Clinical Trials Register (DRKS) identification number: DRKS00012983 (https://www.drks.de/drks\_web/navigate.do?navigationId=trial.HTML&TRIAL\_ID=DRKS00012983), registered on 20 September 2017, first patient enrolled on 21 November 2017. ä IMPLICATIONS FOR REHABILITATION Early rehabilitation of critically ill patients is recommended to prevent and treat the subsequent functional disability, but a suitable measurement instrument for the German-speaking area is lacking. The translated, cross-culturally adapted German CPAx demonstrated excellent validity and reliability in assessing physical function and activity in critically ill adults. Cross-sectional validity of the CPAx has been newly established and allows the use of this tool at clinically relevant time-points in the course of a critical illness. The CPAx-GE can therefore be used in clinical practice by German-speaking therapists to assess physical function and activity during early rehabilitation in the ICU and hospital.

Objectives: To translate and culturally adapt the Chelsea Critical Care Physical Assessment Tool into Swedish and to test the interrater reliability of the Swedish version in critically ill patients. Design: Observational study Methods: Translation and cross-cultural adaptation was performed in line with international recommendations, including forward and backward translation and expert round table discussions. The inter-rater reliability of the Chelsea Critical Care Physical Assessment Tool-Swedish was then explored in 50 critically ill adult patients, pragmatically recruited, in a University Hospital clinical setting. Reliability was calculated using intraclass correlation coefficient for aggregated scores and quadratic weighted Cohen's kappa analysis for individual items Results: The expert round table discussion group agreed that the translation was a satisfactory equivalent to the original version and applicable for use within the clinical setting. Reliability of aggregated scores and individual items were very good (intraclass correlation coefficient of 0.97 and quadric weighted kappa values ranging from 0.88 to 0.98). The measurement error for aggregated scores was low, with a standard error of measurement of 1.79, smallest detectable change of 4.95, and limits of agreement of 5.20 and-4.76. The percentage agreement for individual items ranged from 64% to 88%. Conclusion: The Chelsea Critical Care Physical Assessment Tool-Swedish was found applicable and appropriate for assessment of functioning in critically ill patients in an acute setting in Sweden, and it displayed high inter-rater reliability. This implies that the Swedish version can be used as assessment tool within intensive care and acute wards in Sweden.
SwissScoring--a nationwide survey of SAPS II assessing practices and its accuracy
Swiss medical weekly, 2014
The first description of the simplified acute physiology score (SAPS) II dates back to 1993, but little is known about its accuracy in daily practice. Our purpose was to evaluate the accuracy of scoring and the factors that affect it in a nationwide survey. Twenty clinical scenarios, covering a broad range of illness severities, were randomly assigned to a convenience sample of physicians or nurses in Swiss adult intensive care units (ICUs), who were asked to assess the SAPS II score for a single scenario. These data were compared to a reference that was defined by five experienced researchers. The results were cross-matched with demographic characteristics and data on the training and quality control for the scoring, structural and organisational properties of each participating ICU. A total of 345 caregivers from 53 adult ICU providers completed the SAPS II evaluation of one clinical scenario. The mean SAPS II scoring was 42.6 ± 23.4, with a bias of +5.74 (95%CI 2.0-9.5) compared ...

Background: Outcome measures can assess the change in the health status of a patient in an intensive care unit (ICU). The Chelsea Critical Care Physical Assessment (CPAx) tool is used to assess the functional outcomes to monitor patient progression or regression in an ICU. Objectives: Our study aimed to identify studies that assess the functional outcomes of patients nursed in ICUs that use the CPAx tool. Method: An integrative review framework was used. Data were analysed in five steps to formulate a conclusion that aligned with the objective of our study. Data were extracted from peer-reviewed articles published online between 2013 and 2022. Databases that were used include Google Scholar, Directory of Open Access Journals (DOAJ) and PubMed for reviewed articles. Keywords were used in the search strategy, and screening of abstracts was done to extract studies that met the inclusion criteria. Results: We retrieved 41 studies, of which 11 matched the inclusion criteria. Data were thematically arranged into studies measuring the validity and reliability of the CPAx tool, using the CPAx tool to measure outcomes in the ICU, the tool used at ICU and hospital discharge. Conclusion: The use of the CPAx tool has no impact on measuring the hospital length of stay or quality of life. Clinical implications: The tool is comprehensive and enhances the accuracy of patient assessment.

The aim of this study was to evaluate the usefulness of using Acute Physiology and Chronic Health Evaluation (APACHE) II score and Sequential Organ Failure Assessment (SOFA) score as the predictors of length of stay (LOS) in various surgical intensive care units (ICUs) and to test the hypothesis that the significance of scoring for predicting LOS is greater in specialized surgical ICUs. We scored patients in a non-specialized general surgical ICU (n = 328) and in a specialized cardiosurgical ICU (n = 158) consecutively on admission (APACHE II-1st day; SOFA-1st day) and on third day of stay (APACHE II-3rd day; SOFA-3rd day) in a 4-month period. LOS and APACHE II/SOFA scores were significantly correlated both on admission and on third day of stay in the general surgical ICU (APACHE II-1st day r = 0.289; SOFA-1st day r = 0.306; APACHE II-3rd day r = 0.728; SOFA-3rd day r = 0.725). LOS and APACHE II on admission were not significantly correlated in the cardiosurgical ICU (APACHE II-1st ...
