Patient Activation to Address Chronic Pain and Opioid Management in Primary Care

The PROMIS Global Health score was used to assess general perceptions of health and quality of life. The 10 items that comprise the Quality of Life scale are reported as two dimensions, mental health and physical health. Raw scores for PROMIS Global Physical Health were converted to standardized T-scores using published conversion tables.T-Score distributions are standardized such that a 50 represents the average (mean) for the US general population, and the standard deviation around that mean is 10 points. A high score always represents more of the concept being measured. Thus, a person who has T-score of 60 is one standard deviation better (more healthy) than the general population.

The Patient-Reported Outcome Measurement Information System (PROMIS) Global Health instrument is a system of highly reliable, and precise measures of patient-reported outcomes in physical and mental health and social well-being. Measure of overall health is based on a single item/rating: "In general, would you say your health is:". Answers are reported on scale 1-5, with 1=poor to 5=excellent. Average raw scores are reported, with higher scores reflecting higher functioning.

Depression was measured using the Patient Health Questionnaire-9 (PHQ-9), a reliable and well validated instrument. Mean scores are reported in range 0-27, with higher score indicating severity of depression: mild (5-9), moderate (10-14), moderately severe (15-19) and over 20 indicating severe depression.

Satisfaction with primary care provider is reported on a scale from 1-10, where "1" is the worst possible care and "10" is the best possible care. Mean scores are reported, and higher scores indicates more satisfaction with care.

The Screener and Opioid Assessment for Patients in Pain (SOAPP-5) is a 5 item survey used to identify aberrant behaviors related to long-term opioid treatment. Each item is rated 0 to 4 (with 0=never and 4=very often); ratings are added for all 5 items resulting in a range of possible scores 0-20. A higher score indicates greater risk for patients on long term opioids, and a score of => 4 is considered positive. Results reported are the number and % of participants who score => 4.

The Current Opioid Misuse Measure (COMM) is used to identify aberrant behaviors related to long-term opioid treatment. It is a clinical screening tool for monitoring patients for opioid overuse and misuse in six areas. The COMM contains 17 items with total score range of 0-68, and a score of 9 or greater is considered positive. It uses a low cut off value as it is intended to over-identify misuse. Results reported are the number and % of participants who score => 9.

The 42-item Chronic Pain Coping Inventory (CPCI) is used to assess behavioral and cognitive pain coping strategies. It contains 8 subscales: Guarding, Resting, Asking for Assistance, Relaxation, Task Persistence, Exercising/Stretching, Coping Self-Statements, and Seeking Social Support. For each subscale, patients were asked the number of days (0-7 days) he/she performed each task (4-7 tasks). The mean score for each subscale is reported, with possible range of scores 0-7. The CPCI was developed to assess the behavioral coping strategies that are taught and encouraged during treatment (eg, relaxation, exercising, task persistence), ones that are discouraged (eg, guarding, resting, asking for assistance), and one neutral strategy (seeking social support). Active strategies are defined as adaptive coping responses (eg, staying busy or active), and higher scores are associated with positive coping.

Pain Self-Efficacy Questionnaire (PSEQ) is an established 10-item measure of pain self-efficacy that is widely used in clinical settings to assess confidence in one's ability to work and lead a normal life despite pain. Each item is rated on a 7-point scale with 0= not at all confident and 6=extremely confident. A total score is calculated by summing the scores for each of 10 items, yielding max score of 60. A higher score indicates higher self-efficacy.

Measured with the Patient-Reported Outcome Measurement Information System (PROMIS) Global Health instrument. PROMIS is a system of highly reliable, and precise measures of patient-reported outcomes in physical and mental health and social well-being. Pain intensity is assessed using a single item ("How would you rate your pain, on average?"). The average raw score is reported on scale 1-10, with 1=no pain to 10= worst imaginable.

The Patient-Reported Outcome Measurement Information System (PROMIS) Global Health instrument is a system of highly reliable, and precise measures of patient-reported outcomes in physical and mental health and social well-being. This function domain is based on a single item: "To what extent are you able to carry out your everyday physical activities such as walking, climbing stairs, carrying groceries, or moving a chair?" Answers are reported on scale 1-5, with 1=not at all to 5=completely. Average raw scores are reported, with higher scores reflecting higher functioning.

The Patient-Reported Outcome Measurement Information System (PROMIS) Global Health instrument is a system of highly reliable, and precise measures of patient-reported outcomes in physical and mental health and social well-being. This function domain is based on a single item: "In general, please rate how well you carry out your usual social activities and roles. (This includes activities at home, at work and in your community, and responsibilities as a parent, child, spouse, employee, friend, etc.)" Answers are reported on scale 1-5, with 1=poor to 5=excellent. Average raw scores are reported, with higher scores reflecting higher functioning.

The Communication Assessment Tool (CAT) measures patients' perceptions of physician performance with regard to communication and interpersonal skills. It is a 14-item instrument that asks respondents to rate their primary primary care physician based on the last couple of visits. The answers are reported using a 5-point rating scale, with 1=poor to 5=excellent. Average scores are reported.

The Perceived Efficacy in Patient-Physician Interactions Questionnaire (PEPPI) is used to measure patients' self-efficacy in obtaining medical information and attention to their medical concerns from physicians.Ten questions are measured on a scale from 1 (not at all confident) to 5 (very confident) and the range of possible scores is 10-50. Average scores are reported, with higher score reflecting more confidence in interacting with his/her physician.

Primary care services (number of non-urgent outpatient visits) and acute care services (number of emergency room (ER) visits and inpatient stays) within KPNC as extracted from the electronic health records are reported. Average number of visits are reported for 6 month period prior to baseline, for 3 months prior to 6 month interview, and 6 months prior to 12 month interview. For all three time periods, active membership in Kaiser health plan is required for 4 of 6 months, and 3 of 3 months for the 3-month period used in 6 month analysis.

Use of Kaiser's online portal is extracted from electronic health record. Results are reported as number and % of patients who used the portal during specified time periods: 1) 6 month period prior to baseline, 2) 3 months prior to 6 month interview, and 3) 6 months prior to 12 month interview. For all three time periods, active membership in Kaiser health plan is required for 4 of 6 months, and 3 of 3 months for the 3-month period used in 6 month analysis.

Use of Kaiser's online portal (kp.org) was reported by participants on questionnaire at baseline, 6 and 12 months. Participants were asked different ways in which portal was used, and if they used kp.org's health and wellness resources (healthy lifestyle programs, wellness coaching, audio podcasts, recipe blogs, tools/calculators, videos). Results reported here are number and % of patients who reported using Kaiser's online health and wellness resources during specified time period ("ever" at baseline, and "past 6 months" at 6/12 months).

Attendance at Kaiser's health education classes was reported by participants on questionnaire at baseline, 6 and 12 months. Results are reported as number and % of patients who attended health education class during specified time period ("ever" at baseline, and "past 6 months" at 6/12 months).

Opioid prescription dispensations were extracted from electronic health records and converted into morphine milligram equivalent (MME), by multiplying the quantity of each prescription by the strength of prescription (milligrams of opioid/unit dispensed). The resulting product is then multiplied by the conversion factor for MMEs. We calculated the average daily MME dispensed for the relevant time periods. Results are reported for 3 time periods: 1) 6 months prior to baseline, 2) 3 months prior to 6 month interview, and 3) 6 months prior to 12 month interview. For all 3 time periods, active membership in Kaiser health plan is required for 4 of 6 months, and 3 of 3 months for the 3-month period used in 6 month analysis.
