Brief Summary

Cognition is the way people use their brains to think, understand, remember and make decisions. Cognitive changes are often seen even up to 1 year after surgery. Whether these changes are more than what is expected for someone's age and morbidities is still uncertain. Due to the COVID-19 emergency, many elective surgeries have been delayed, which is stressful for patients, but also represents an opportunity of understanding better how surgery can impact cognitive abilities. The purpose of this study is to explore if and how cognitive performance changes over time for patients aged 65 years or older, whose surgery has been postponed. due to the COVID-19 emergency, following and assessing the cognitive performance of these patients over time before and after surgery. In particular, in this study, the participant's cognitive performance will be assessed periodically with a computer-based instrument for cognitive testing, self-administered at home, in which tests are based on playing cards.

Outcome Measures

Primary Outcomes (1)

  • Change in perioperative cognitive trajectories assessed using the Cogstate Brief Battery (CBB)

    CBB is a computer-based cognitive test extensively validated against standard neuropsychological batteries in cognitively normal older adults, as well as in patients with cognitive impairment, in the community and in different clinical contexts, both in a clinician/researcher-supervised manner, and in an unsupervised fashion. It has been used also in the perioperative setting, showing equivalent or greater reliability, and greater sensitivity than conventional batteries. It consists of four tasks (Detection Task, Identification Task, Learning Task, and One-Back Task) designed to assess psychomotor function, attention, working memory, and visual learning. Each task utilizes stimuli in the form of playing cards. Stimuli characteristics (e.g., color, suit) are manipulated based on the requirements of each task.

    After 1-5 days from the initial recruitment, each participant will self-administer the cognitive testing once, and then every month until surgery. Postoperative assessments at 1, 3, 6 and 12 months postoperative

Secondary Outcomes (2)

  • Pain trajectories using the Numeric Pain Rating Scale

    Baseline assessment after 1-5 days from the initial recruitment and then every month until surgery. Postoperative assessments at 1, 3, 6 and 12 months postoperative

  • Depressive symptoms trajectories using the Geriatric Depression Scale (short form) (GDS)

    Baseline assessment after 1-5 days from the initial recruitment and then every month until surgery. Postoperative assessments at 1, 3, 6 and 12 months postoperative
