An Artificial Intelligence Driven Approach to Optimize Patient Selection for a Transitional Pain Service

TPS-Select is a computer-based tool that helps the research team identify patients who may be eligible for this study. It uses information that already exists in the medical record at the time a surgery is scheduled to estimate the chance of developing ongoing pain after surgery. This information can include details about the planned surgery, prior medical conditions, past surgeries, and previous use of pain medications. The tool runs automatically and is used only to help the research team decide whom to contact about possible participation in the study. The risk estimate created by this tool is not added to the medical record and is not seen by the patient's care team. Only approved members of the research team can see this information through a secure research system.

A pharmacist will meet with patients as part of the Transitional Pain Service before and after surgery. During this visit, the pharmacist will work with patients to create a personalized pain management plan, using the medications stated in this intervention to help safely and effectively control pain. This will guide patients on the proper use of opioid analgesics and non-opioid analgesics, including acetaminophen, non-steroid anti-inflammatory drugs, gabapentinoids, and topical medications to manage surgical pain.

If a patient has significant pain after their surgery, the care team may evaluate the patient for additional pain-relief options, such as the interventional pain procedures listed above. Local numbing medication or imaging studies may also be used to ensure the treatment is safe and appropriate. All anesthesiologists on the pain service are specially trained to perform these procedures. Only approved procedures will be offered, along with any imaging needed for evaluation.

Patients will be asked to complete short online pain education modules to help set expectations and prepare for pain after surgery. These materials are available at https://www.transitionalpainservice.ca/learn. Each patient will also be screened for mood-related concerns, including symptoms of depression, using a brief questionnaire. If a patient has significant symptoms of depression, they may be referred to a pain psychologist and, if needed, a UCSF psychiatrist for additional support. These visits may include proven approaches such as cognitive behavioral therapy, acceptance and commitment therapy, and mindfulness-based strategies to help patients manage pain, cope with stress, and improve daily functioning. Patients with milder symptoms may be referred to group-based pain psychology sessions led by a pain psychologist.

Patients will be assessed for their physical function and ability to carry out daily activities. If a patient has difficulty with mobility, strength, or endurance, they may be referred to physical or occupational therapy before surgery to help improve overall conditioning. Pre-surgery therapy may include exercises to strengthen the core, arms, and legs, improve balance, and build stamina, as well as an overall fitness assessment. Referrals will only be made if it is safe for the patient to participate, and standard safety checks-such as heart health and fall risk-will be completed beforehand. All therapy will be provided by a licensed physical therapist using established, evidence-based treatment plans.
