About this study

Official title: N-of-1 Trials Using mHealth in Chronic Pain Aka PREEMPT (Personalized Research for Monitoring Pain Treatment)

Chronic musculoskeletal pain is an important problem, and treatments are often prescribed in a "trial and error" fashion. Clinicians prescribe a treatment to a patient and then wait and see if the treatment is successful. If the treatment is unsuccessful, they will try a different treatment. The disadvantage to this method is that it may take a long time to find a successful treatment.

The purpose of the PREEMPT Study is to test whether using a mobile phone application ("Trialist app") that allows patients and their health care providers to run personalized experiments comparing two pain treatments is more effective than usual care. Patients download the app, and working with their clinicians, set up a personalized trial that makes sense for them. Every day they answer questions to track levels of pain and side effects of treatment, such as fatigue and constipation. Once the personalized trial has ended, the responses to these daily questions on each treatment will be compared. During a regular clinic visit, the patient and the clinician will review visual displays of the results to facilitate treatment decision-making. Approximately 250 patients will be enrolled in the study. Half the patients will use the app and review results with the clinician, and half the patients will continue with their regular care (i.e., will not use the app). The two groups will be compared to see if using the app is successful in improving long term pain outcomes. The goal of the intervention using the Trialist app is to help patients engage actively and collaboratively with their clinicians and identify effective treatments more quickly.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From Baseline in Pain-related Interference on the Patient Reported Outcomes Measurement Information System (PROMIS) Scale at 26 Weeks

    Pain interference measured with Patient Reported Outcomes Measurement Information System (PROMIS) Scale 8-item short form at baseline and 26 weeks which measures self-reported consequences of pain on relevant aspects of one's life. The final score is represented by the T-score, a standardized score with a mean of 50 and a standard deviation of 10. Pain interference scores range from 0 - 100. For pain interference, higher scores indicate greater pain interference. Data table measures show change over time with negative numbers indicating improvement (decreases) and positive numbers indicating increases in pain interference.

    Measured: baseline, 26 weeks

Secondary outcomes (10)
  1. Longitudinal Change From Baseline up to 52 Weeks Follow-up in Pain-related Interference on the Patient-Reported Outcomes Measurement Information System (PROMIS) Scale

The final score is represented by the T-score, a standardized score with a mean of 50 and a standard deviation of 10. Pain interference scores range from 0 - 100. For pain interference, higher scores indicate greater pain interference. Data table measures show change over time with negative numbers indicating improvement (decreases) and positive numbers indicating increases in pain interference.

    Measured: baseline, 13 weeks, 26 weeks, 52 weeks

  2. Longitudinal Change From Baseline up to 52 Weeks Follow-up in Pain Intensity on the Patient-Reported Outcomes Measurement Information System (PROMIS) Scale

    Pain intensity measured with Patient-Reported Outcomes Measurement Information System (PROMIS) 3a short form at baseline, 13 weeks, 26 weeks, and 52 weeks which measures self-reported estimate of how much a person hurts. The final score is represented by the T-score, a standardized score with a mean of 50 and a standard deviation of 10. Pain intensity scores range from 0 - 100. For pain intensity, higher scores indicate greater pain intensity. Data table measures show change over time with negative numbers indicating improvement (decreases) and positive numbers indicating increases in pain intensity.

    Measured: baseline, 13 weeks, 26 weeks, 52 weeks

  3. Longitudinal Change From Baseline up to 52 Weeks Follow-up on the Patient-Reported Outcomes Measurement Information System (PROMIS) MENTAL Global Health Scale

    Global health measured with 10 item Patient-Reported Outcomes Measurement Information System (PROMIS) Global Health scale at baseline, 13 weeks, 26 weeks, and 52 weeks, representing physical and mental health components. Global mental health measures mental health, quality of life, satisfaction with social activities and emotional problems. The final mental health score is represented by the T-score, a standardized score with a mean of 50 and a standard deviation of 10. Global mental health scores range from 0 - 100, and higher scores indicate better mental health. Data table measures show change over time with positive numbers indicating improvement in global mental health and negative numbers indicating declines in global mental health.

    Measured: baseline, 13 weeks, 26 weeks, 52 weeks

  4. Longitudinal Change From Baseline up to 52 Weeks Follow-up on the Patient-Reported Outcomes Measurement Information System (PROMIS) PHYSICAL Global Health Scale

    Global health measured with 10 item Patient-Reported Outcomes Measurement Information System (PROMIS) Global Health scale at baseline, 13 weeks, 26 weeks, 52 weeks, representing physical and mental health components. Global physical health measures overall physical health, physical function, pain and fatigue. The final physical health score is represented by the T-score, a standardized score with a mean of 50 and a standard deviation of 10. Physical global health scores range from 0 - 100, and higher scores indicate better physical health. Data table measures show change over time with positive numbers indicating improvement in global physical health and negative numbers indicating declines in global physical health.

    Measured: baseline, 13 weeks, 26 weeks, 52 weeks

  5. Longitudinal Change From Baseline up to 52 Weeks Follow-up in Analgesic Adherence (Overuse) on the Pain Medication in Primary Care Patient Questionnaire

    Four questions from the Pain Medication in Primary Care Patient Questionnaire measured adherence to medications at baseline, 13 weeks, 26 weeks, 52 weeks. Two questions comprised a subscale assessing overuse of medications. Overuse scores range from 0 - 100. Higher scores indicate greater adherence and less overuse of medications.
