Description of intervention(s) / exposure
Brief name: a text message-based survey to follow-up post-operative sleep disruption.

Patients >18 years old undergoing non-cardiac day surgery at Wellington Hospital or Kenepuru Hospital who consent to participate in the study will have their cellphone number recorded for the text-based survey link. The first survey will be sent to each participant, 24 hours post-discharge, by text (or by email if there is no cellphone number) to their smartphone. If the patient responds to the first survey request, they will receive two further surveys, one on day 3 postoperatively, and one on day 7 postoperatively.

Statistical methods / analysis
As there is currently no known level of sleep disruption deemed to be clinically significant no formal hypothesis test will be undertaken. Rather, differences in mean (or median if data is non-parametric) sleep quantity and quality will be assessed independently between pre-operative values and values obtained on post-operative days 1, 3, and 7 with a point estimate and attendant 95% confidence interval. An interval that crosses the null value (a difference of 0 hours in the case of sleep quantity, and a difference of 0cm in the case of sleep quality) would be deemed insufficient evidence to conclude there is a difference in that outcome on that post-operative night compared to pre-operative values.

Two separate multivariate linear models will be used to investigate the association between the other variables collected and sleep quality and quantity.

No correction will be made for multiple testing as the aim of this study is hypothesis generation; conclusions should therefore be treated as such.
