Validity and Reliability of Korean Version of AM-PAC Inpatient Short Form (Low Function) in Critically Ill Patients

NCT ID: NCT06440265

Last Updated: 2024-06-03

Basic Information

• Recruitment Status: COMPLETED
• Total Enrollment: 38 participants
• Study Classification: OBSERVATIONAL
• Study Start Date: 2023-03-31

Brief Summary

The Activity Measure for Post Acute Care (AM-PAC) inpatient short form (low function) evaluates the level of assistance a patient requires another person to provide for distinct functional mobility and daily activities. The objective of the study was to translate and cross-culturally adapt the AM-PAC (low function) into Korean version and assess its reliability and validity .

Independent raters assessed 38 patients from ICU using the Korean version of AM-PAC, respectively. Intra-class correlation coefficients (ICCs) and Bland-Altman's plots were used to evaluate reliability, and Cronbach's alpha for internal consistency. Validity was evaluated using Spearman's correlation analysis with other physical function assessment tools (functional status score for the ICU(FSS-ICU), Medical Research Council-sum score(MRC-SS), hand grip strength) and other unrelated factors (body mass index, glucose level).

Detailed Description

The Activity Measure for Post Acute Care (AM-PAC) inpatient short form (low function) evaluates the level of assistance a patient requires another person to provide for distinct functional mobility and daily activities. The objective of the study was to translate and cross-culturally adapt the AM-PAC (low function) into Korean version and assess its reliability and validity.

An expert committee in intensive care unit (ICU) rehabilitation supervised the forward and backward translation process and to finalize the Korean version of AM-PAC (low function).

First evaluation of AM-PAC basic mobility and daily activity inpatient short forms was conducted on the first rehabilitation treatment day in ICU by the primary therapist. Subsequently, follow-up evaluations are conducted at 2 weeks and 4 weeks until the patient is discharged. Paired raters observed and recorded the scores independently. Each therapist was unaware of the other rater's scores, and they did not communicate verbally during the assessment. Starting with the first evaluation in the ICU, the same inter-rater reliability evaluation was performed in week 2 and week 4.

Raters assessed 38 patients from Medical ICU using the Korean version of AM-PAC. Intra-class correlation coefficients (ICCs) and Bland-Atman's plots were used to evaluate reliability, and Cronbach's alpha for internal consistency.

Then, convergent validity was evaluated using Spearman's correlation analysis between AM-PAC score and other physical function assessment tools (FSS-ICU, MRC-sum score, hand grip strength), and divergent validity was evaluated using correlation analysis between AM-PAC score and BMI or serum glucose level.

Conditions

Post Intensive Care Syndrome; Intensive Care Unit Acquired Weakness

Study Design

• Observational Model Type: CASE_ONLY
• Study Time Perspective: PROSPECTIVE

Interventions

AM-PAC inpatient short form (low function)

The Activity Measure for Post-Acute Care(AM-PAC) "6-clicks" instruments have advantages in that they are simple and quick to complete, easy to use within usual care and has been validated in the entire hospital population. It has gained broad adoption in acute care hospital and, although it includes items for people at lower levels of function, there is a concern of a floor effect in ICU measurement. So, new AM-PAC items are developed to measure physical function at the lowest level and added 2 new items to AM-PAC inpatient mobility short form. It lowered the floor effect and increased statistical power, measurement breath, and sensitivity.

2 new items

• Turning head
• Following simple instructions
