Surgery and its resulting hospitalisation are associated with subsequent cognitive and functional decline. Interventions to reduce this decline have exhibited limited success. Prehabilitation is the process of enhancing capacity and reserve before an acute stressor to improve tolerance of the acute physiologic insult. Older adults requiring major surgery are an ideal population for prehabilitation. Prehabilitation exercise studies have mostly focused on physical training to improve physical outcomes after specific surgery types, and data on cognitive outcomes and in broader surgical populations are needed. Computerised cognitive training (CCT) has been shown to enhance memory, processing speed, attention and multitasking. Combining CCT with a physical exercise may be most effective in reducing cognitive and functional decline in older patients undergoing major surgery, but has yet to be evaluated.

The COgnitive and Physical Exercise to improve Outcomes after Surgery (COPE-iOS) study is a randomised, controlled, participant and assessor blinded clinical trial testing the hypothesis that a pragmatic programme combining CCT and physical exercise throughout the perioperative (ie, preoperative and postoperative) period will improve long-term cognitive and disability outcomes in older surgical patients at high risk for decline. The trial aims to randomise 250 patients who undergo major surgery for a treatment period of approximately 1 month prior to surgery and 3 months after surgery, with a follow-up period of 12 months after surgery. The primary outcome is global cognition at 3 months after surgery. Key secondary outcomes include global cognition at 12 months after surgery and disability in activities of daily living and depression at 3 and 12 months after surgery.

Trial protocol has been approved by Vanderbilt Human Research Protections Programme (#202496) and an independent Data Safety Monitoring Board. Results will be presented at scientific conferences and submitted for publication.

To compare primary care for depression among patients detected in the first 21 months of the SARS-CoV-2 pandemic to patients detected pre-pandemic, and examine whether depression care was associated with patient characteristics.

Retrospective pre–post study using de-identified data from electronic medical record data from the Canadian Primary Care Sentinel Surveillance Network (CPCSSN).

Primary care clinics enrolled in CPCSSN from 1 January 2018 to 31 December 2021.

Patients with a valid CPCSSN case definition of depression detected between 01 January 2018 and 31 December 2021 were included in the cohort and categorised by detection date (pre-pandemic or during Canadian pandemic waves).

Primary care encounters, psychotropic prescriptions and selective serotonin reuptake inhibitor (SSRI) prescriptions were observed at 3 and 12 months post-detection. Multivariable regression evaluated associations between patients’ depression detection timing and depression care, adjusting for age, sex, rurality, neighbourhood deprivation quintile, province, number of observable comorbidities and pre-detection psychotropic use.

91 453 patients with depression were identified, of whom 53% were detected pre-pandemic. Patients detected during the pandemic were younger and less comorbid than those detected pre-pandemic. Proportions of patients with any encounter, psychotropic prescriptions and SSRI prescriptions were higher for patients detected during every pandemic wave compared with patients detected pre-pandemic. The adjusted incidence rate ratios (aIRRs) of number of encounters (aIRR=1.15; 95% CI 1.13 to 1.17), psychotropics (aIRR=1.11, 95% CI 1.09 to 1.13) and SSRIs prescribed (aIRR=1.12; 95% CI 1.10 to 1.15) within 3 months of detection were higher among patients detected during the first pandemic wave compared with those detected pre-pandemic. Socio-demographic characteristics had weaker associations with outcomes compared with timing of detection. Results were similar within 12 months of detection.

Overall, primary care for depression was maintained during the pandemic despite challenging circumstances. Increases in paediatric encounter rates and increased prescribing in younger adults warrant further investigation to understand the factors driving these patterns.
