Description of intervention(s) / exposure
Body temperature of patients undergoing endoscopic procedures with procedural sedation will be continuously monitored immediately prior, during and immediately after the procedure. Endoscopic procedures including lower endoscopy and complex upper endoscopy procedures, which are anticipated to exceed 30minutes in duration will be included. Continuous temperature monitoring will be commenced by the Research Nurse, and retrieved retrospectively.
Participants will be asked to complete surveys on:
- Thermal comfort via a 100mm visual analogue scale at baseline, pre-procedure and post-procedure timepoints
- Satisfaction via the 21-item gastrointestinal endoscopy satisfaction questionnaire (GESQ) at one day post-endoscopy via email or hard copy questionnaire. Anticipated time to complete: 15 minutes. Reference: Hutchings HA, Cheung W-Y, Alrubaiy L, et al. Development and validation of the gastrointestinal endoscopy satisfaction questionnaire (GESQ). Endoscopy. 2015;47(12):1137-43.
Follow up - one day post-procedure (for completion of GESQ - see above).
The temperature monitoring device to be used in not novel, in that it is available and approved for use in Australia and used in perioperative and procedural settings for monitoring temperature. It will only be applied to patients who choose to enrol to allow for a consistent method of measuring temperature in this study. Whilst in this local setting, patients do not consistently receive temperature monitoring, ACSQHC recommend that temperature is a minimum requirement for inclusion in patient monitoring plans (National Consensus Statement: Essential elements for recognising and responding to acute physiological deterioration (ACSQHC, 2017). Therefore, temperature monitoring should be standard practice and our choice of device needs to be consistent to meet the aims of this observational study, just as the tools we used to measure thermal comfort or satisfaction are. We are not testing the utility or accuracy or applicability of the device. Therefore, this study is not an interventional study.

Statistical methods / analysis
Participant characteristics, as well as surgical and anaesthetic variables, will be summarised descriptively via counts and percentages for categorical data, and means/standard deviations, medians/ranges, as appropriate for continuous data. Mean ambient temperature, shivering and thermal comfort scores at each procedural stage will be reported. Temperature decline will be analysed using linear mixed-model analysis (to allow for fixed effects of baseline temperature and time, and a random intercept for repeated measures) from baseline to the end of procedure, and baseline to end of recovery period. A significance level of p<0.05 will be utilised. SPSS™ Version 26 will be utilised for data analysis.

Summary
Brief summary
This project aims to determine how many patients that receive sedation for endoscopy procedures (in this study referred to as 'procedural sedation') experience heat loss. The project also aims to investigate the pattern of heat loss. No guidance exists for prevention of hypothermia (heat loss to below 36 degrees Celsius related to a surgical procedure) for patients receiving procedural sedation during endoscopy. This means that patients remain exposed toside effects related to heat loss: for example, discomfort related to feeling cold, and prolonged recovery. Whilst temperature measurement during procedural sedation is often neglected entirely, in this project we will use a temperature monitoring device that is non-invasive and provides continuous monitoring of temperature. New knowledge to guide future interventions to prevent heat loss for patients receiving sedation for endoscopy procedures will be generated.
