From: The effectiveness of telemedicine for paediatric retrieval consultations: rationale and study design for a pragmatic multicentre randomised controlled trial

Outcome measure

Statistical Method

P1

Stabilisation time1

Linear regression with stabilisation time as the outcome, type of consultation as the main effect and PIM3 score as a co-variable

S1

Change in patient’s physiological status

Linear mixed effects model with physiological status as outcome, type of consultation and time as main effects, and a consultation-by-time interaction term.

S2

Change in diagnosis

Logistic mixed effects model with diagnosis as outcome, type of consultation and time as main effects, and a consultation-by-time interaction term.

S3

Destination of retrieved patients

Logistic regression with destination as outcome and type of consultation as the main effect.

S4

Retrieval decision

Logistic regression with retrieval decision as outcome and type of consultation as the main effect.

S5

PICU LoS1

Linear regression with LoS as the outcome, and type of consultation as the main effect.

  1. 1Data relating to stabilisation time and PICU LoS will transformed if necessary to meet assumptions of regression model.
