Design outcomes

Primary

MeasureTime frame
ED: Riker�s Sedation-Agitation Scale (SAS) Highest value is considered for data analysis. POD: Confusion Assessment Method (CAM) will be used to evaluate POD. Cognitive function at 3 and 6 months after recruitment to study will be assessed using Brief Screen for Cognitive Impairment (BSCI)-telephonic instrument Timepoint: ED: Riker�s Sedation-Agitation Scale (SAS) Highest value is considered for data analysis. POD: Confusion Assessment Method (CAM) will be used to evaluate POD. Cognitive function at 3 and 6 months after recruitment to study will be assessed using Brief Screen for Cognitive Impairment (BSCI)-telephonic instrument

Secondary

MeasureTime frame
1. To examine the association of ED with POD after cranial and spinal surgeries 2. To identify peri-operative risk factors of ED and POD and its effect on short term and long term outcomes 3) To study the effect of acute postoperative pain on ED and POD, and of persistent pain on POCDTimepoint: During the hospital stay, at 3 and 6 months post recruitment
