Reliability and Validity of a New Postoperative Track Assessment Tool

Study Overview
=================
Brief Summary
-----------------
This prospective observational study investigated the validity and reliability of a new postoperative track assessment tool. We hypothesized, first, that this tool estimates the indication and benefit of a management in an intermediate care unit (IMC). Second, we hypothesized that a) health care providers of IMC or postoperative anaesthesia care unit (PACU) have similar estimations using this tool and b) that this estimation is accurately established in the first 2 hours.

Detailed Description
-----------------
The tool includes 2 visual analog scale (VAS) scores estimating indication of an IMC admission and benefit of an IMC stay. The tool was tested in a PACU and in an IMC unit of a Swiss tertiary centre in 2019/2020 (before COVID pandemic). Three raters: one nurse, one physician in charge and the consultant physician, were asked to fill the VAS at the same time for each included patient. The score was done in the 2 first hours following admission in the unit and during the multi professional morning round at day 1. Reliability was estimated by testing internal consistency (homogeneity), interrater reliability and agreement and test-retest validity (stability). Validity included content validity, construct validity and criterion validity.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Intermediate Care (IMC) indication (VASi) | Health care raters graded the IMC indication (or allocative efficiency) for each patient on a visual analog scale grading from 0 (very low indication of an IMC management) to 100 (very high indication of an IMC management), namely VASi. | 2019/2020 | 
| Intermediate Care benefit (VASb) | Health care raters graded the IMC benefit (or health gain) for each patient on a visual analog scale grading from 0 (very low benefit from an IMC management) to 100 (very high benefit from an IMC management), namely VASb. | 2019/2020 |
