Change in the number of cancellations with 2 beds added to the ward^*

Sequence of surgical operations	Surgeon schedule, mean (95% CI)
	Base + 2 beds	LOS↑ + 2 beds
Base sequence	−27.5 (−34.3 to −21.4)	−38.1 (−49.6 to −26.6)
Time↑	−34.7 (−42.6 to −26.7)	−40.7 (−52.5 to −28.9)
Time↓	−27.9 (−33.7 to −22.2)	−35.7 (−44.5 to −26.9)
Var↑	−44.4 (−50.5 to −38.3)	−47.9 (−68.9 to −26.8)
Var↓	−19.7 (−33.9 to −5.5)	−24.8 (−36.7 to −12.9)

CI = confidence interval; LOS = length of stay.

^*We took into account the base surgeon schedule and the LOS↑ surgeon schedule, as well as the 4 patient scheduling rules.
