Arm && Interventions

Group	Intervention	Description
off-hours	off-hours	Hip surgeries with anesthesia beginning between 18:00 and 7:59 were coded as "off-hours". Besides, taking the long duration of hip surgery into account, if the anesthesia began before 18:00 but ended after 20:00, it was also defined as "off-hours".
on-hours	on-hours	Hip surgeries with the start time of anesthesia between 8:00 and 17:59 were coded as "on-hours".
