Brief Summary:
The incidence of post-operative delirium in the South-east Asian population is not known. Through a prospective, single centre, observational study, the investigators aim to characterize the incidence and risk factors of delirium in older adults undergoing elective total joint arthroplasties (TJA). The study will recruit eligible patients (65 - 90 years old undergoing elective TJA), with a targeted sample size of 500. Patients will be screened for dementia and Confusion Assessment Method (CAM) scores obtained pre and post operatively. Other data such as preoperative Charlson comorbidity index (CCI), post op complications using Post operative Morbidity Survey (POMS), pain scores, readmission rates and length of hospital stay (LOS), functional and health-related quality-of-life (HRQoL) will also be collected and analysed.

Primary Outcome Measures :
  1. Post operative delirium incidence [ Time Frame: Up to 30 days ]
    Measured using confusion assessment method (CAM) tool

Secondary Outcome Measures :
  1. Post operative complications [ Time Frame: Up to 30 days post operatively ]
    measured using post operative morbidity survey (POMS)

  2. incidence of post operative nausea and vomiting (PONV) [ Time Frame: post op day 1 ]
    the total number of patients experiencing PONV

  3. Length of hospital stay [ Time Frame: up to 12 months ]
    the total number of days stayed in hospital during this elective admission

  4. Hospital readmission rate [ Time Frame: 30 days post operative ]
    the percentage of patients being readmitted for a complication related to the surgery

  5. functional and health-related quality-of-life (HRQoL) [ Time Frame: 6 months , 12 months ]
    tools used to assess knee function, ADL status, emotional and social wellbeing

  6. Days Alive and Out of Hospital (DAOH) [ Time Frame: 1 month, 6 months, 12 months ]
    measures the death rate and total summation of days spent outside of hospital following the surgery
