Conditions

Cognitive Function Abnormal, Lung Cancer, Pain, Postoperative

Brief summary

More than 30% of patients undergoing thoracic surgical procedures develop persistent post-surgical pain (PPSP), which results in impaired functioning, diminished quality of life, and increased risk of chronic opioid use. The proposed project aims to determine whether a prospective, randomized, controlled study of smartphone-based perioperative cognitive flexibility training will reduce the incidence of PPSP in high-risk individuals undergoing thoracic surgery.

Interventions

BEHAVIORALCOFLEX neurocognitive training

The COFLEX training group will then be provided with the cognitive training module and participants will be required to complete a targeted 30-minute daily training until the day of surgery, and then after the surgery, for a total of 6 weeks.

The control (crossword puzzles) group will be given a training module, where they can access crossword puzzles on the same platform, and can do puzzles whenever they desire over the 6-week time period.

Masking description

All study team members will be blinded to the subject assignment to either intervention (cognitive flexibility training) or control groups (crossword puzzle training), except one coordinator who will monitor participant adherence with the cognitive flexibility training, and send prompts or contact participants to understand barriers to adherence.

Inclusion criteria

* Adults age 18 to 75 undergoing thoracic surgery * Access to an active email account * Score \<50th percentile on Color Word Matching Stroop Test (CWMST) normalized T-score

Exclusion criteria

* Unable to complete cognitive testing * Color blindness assessed via self-report * Participants who do not speak or read English The inclusion criteria for the observational cohort will be the same, with the exception of Score ≥50th percentile on Color Word Matching Stroop Test (CWMST) normalized T-score.

Design outcomes

Primary

MeasureTime frameDescription
The presence of clinically meaningful persistent post-surgical pain 3 months after surgery3 months after surgeryParticipants will be asked about pain at or around their surgical area (dichotomous yes/no answer), and rate the intensity of pain, if present, on 0-10 numerical rating scale, where 0=no pain, and 10=worst imaginable pain. The presence of PPSP will be compared between the intervention arm and the control arm

Secondary

MeasureTime frameDescription
Brief Pain Inventory pain severity1 and 3 months after surgeryBPI (brief pain inventory) severity score will be compared between the study arms. BPI severity score ranges from 0 (least) to 10 (worst)
Brief Pain Inventory pain interference1 and 3 months after surgeryBPI (brief pain inventory) interference score will be compared between the study arms. BPI interference score ranges from 0 (least) to 10 (worst)
PROMIS Anxiety Score3 months after surgeryPROMIS® (Patient-Reported Outcomes Measurement Information System) is a set of person-centered measures that evaluates and monitors physical, mental, and social health. Each item on the measure is rated on a 5-point scale (1=never; 2=rarely; 3=sometimes; 4=often; and 5=always) with a range in score from 7 to 35 with higher scores indicating greater severity of anxiety. The score will be compared between the arms
PROMIS Depression score3 months after surgeryPROMIS® (Patient-Reported Outcomes Measurement Information System) is a set of person-centered measures that evaluates and monitors physical, mental, and social health. Each item on the measure is rated on a 5-point scale (1=never; 2=rarely; 3=sometimes; 4=often; and 5=always) with a range in score from 7 to 35 with higher scores indicating greater severity of depression. The score will be compared between the arms.
