Data Collection
ADVERSE EVENTS
The participants’ sociodemographic (age, sex, marital status, living arrangement [living alone or not], and educational level) and clinical (current medication regimen and medical history) data were collected by the blinded outcome assessor at the beginning of the preanesthetic assessment clinic session (T0, baseline), close to the end of the clinical session immediately after the intervention (T1, postintervention), before transference to the operation theater (at ward) or after admission to the operation theater (at the reception area) (T2), and between 24 and 48 hours after the surgery (T3). If any psychosomatic discomfort reaction was observed in participants, the intervention would be terminated, and corresponding support would be provided to help them relax. Any adverse events were reported to the institutional review board of the Chinese University of Hong Kong.
