Advancing Cognition and Cognitive Reserve Before ELective Surgery to Enhance Cognitive Recovery And TrajEctories (ACCELERATE)Trial: a Pilot Multicenter Randomized Trial

The Advancing Cognition and Cognitive reserve before ELective surgery to Enhance cognitive Recovery And TrajEctories (ACCELERATE) Pilot Trial estimates whether our novel, coach-supported cognitive prehabilitation strategy will achieve adequate intervention adherence in the context of a feasible multicenter trial protocol.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Background: Delirium, a fluctuating, acute disturbance in attention and awareness, develops in 15-50% of older adults after major surgery. Promising, early stage evidence suggests that cognitive prehabilitation could decrease the absolute risk of postoperative delirium by 10% or more. However, multicenter trials that feasibly optimize cognitive prehabilitation adherence amongst populations most likely to benefit from the intervention are required to advance cognitive prehabilitation toward routine practice.

Overarching Aim: The ACCELERATE Pilot Trial will estimate whether our novel, coach-supported cognitive prehabilitation strategy will achieve adequate intervention adherence in the context of a feasible multicenter trial protocol.

Methods:

Design, setting and participants: The ACCELERATE Pilot trial is prospective single-arm interventional pilot trial.

People >/= 60 years old with Clinical Frailty Scale (CFS) score >/= 4 having inpatient abdominal, orthopedic, spine, thoracic, pelvic, head-and-neck, and vascular surgery with expected time to surgery >/= 4 weeks will be included.

Intervention: Our intervention is a home-based, online, adaptive, multidomain cognitive prehabilitation program, using a cognitive training platform (Lumosity [Lumos Labs]), enhanced by theory- and evidence-informed structured coaching.

Outcomes and sample size: Primary outcome is intervention adherence. Secondary outcomes are monthly recruitment and fidelity to delirium assessment. Our pilot sample size of n=103 is designed to provide 80% power at a 5% level of significance to test whether the proportion of adherent patients exceeds our feasibility target of 75%.

Expertise: Our team features multidisciplinary clinical and methodological experts, nationally representative knowledge users and patient representatives.

Expected outcomes: The ACCELERATE Pilot Trial will derive robust estimates of intervention adherence when supported by structured coaching, as well as trial protocol feasibility. If the pilot trial is feasible, we will proceed with the full ACCELERATE Trial, which will be powered to estimate the effectiveness of cognitive prehabilitation in reducing delirium along with partner-prioritized secondary outcomes.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Intervention adherence
Time Frame: From baseline until surgery; intervention duration varies by participant and continues through the preoperative period (minimum of 4 weeks pre-surgery)
≥75% of intervention participants completing >/=10 hrs of cognitive prehabilitation

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
