While significant advances in pain management have occurred in the last 20 years, the majority of patients with chronic pain (CP) are unable to access evidence-based treatment at either the primary or tertiary care level.
Moreover, research has shown that unrelieved CP and the lack of available expertise contribute to emergency department (ED) visits and hospital admissions. At The Ottawa Hospital (TOH), close to 18,000 ED visits per year are related to CP (12.9%). Among high frequency visitors (HFV; >= 8 visits per year), a small number of patients with CP use an inordinate amount of acute care resources. The investigators study will use a randomized controlled (RCT) design to conduct a pilot evaluation of the impact of a Complex Interdisciplinary Pain Assessment Program (CIPAP) linked with primary care physicians (PCP) compared to a treatment as usual (TAU) control arm.
The investigators hypothesis is that implementing a CIPAP will increase health care value through improved patient outcomes and reduced costs in HFV with chronic pain (CP-HFV). The investigators believe that a CIPAP will provide CP-HFV patients long-term pain management solutions, ED visits for CP will be reduced, and hospital admissions for CP will be prevented. This pilot RCT study will inform a larger-scale RCT study to be conducted in the future.
As this is a phase 2 trial, the sample size is primarily determined by logistical constraints; however, as this trial will yield valuable information about the preliminary impact of the program for planning a larger, more definitive trial in the future, we determined the maximum width of a two-sided 95% confidence interval around the differences between the arms at 12 months. For self-report measures, 18 patients per arm would yield a margin of error of 0.65 standard deviations (total width of confidence interval = 1.3 on the standard deviation unit scale), which is considered acceptable for the self-report measures. For number of visits over 3 months, we assumed a standard deviation of 3 (based on our preliminary data). Assuming approximate normality, our sample size of 18 patients per arm would yield a margin of error of 2 visits (total width of confidence interval = 4 visits) which is adequate to yield preliminary evidence of change. These are conservative estimates as our analyses will include repeated measures, and adjust for baseline measures of response in addition to other demographic and clinical covariates. To account for 20% attrition, we will plan to enrol 23 participants per arm (total number of participants =46).

| Baseline and 12 months post-enrollment |
| Change from baseline in self-reported anxiety, as measured by the Generalized Anxiety Disorder Scale - 7, at 12-months post-study enrollment | Generalized Anxiety Disorder Scale-7 (GAD-7): The GAD-7 will be used to evaluate symptoms of anxiety. It is a 7-item self-report measure that uses a 4-point Likert scale allowing participants to rate themselves with scores of either 0,1,2 or 3 (representing answers of "not at all," "several days," "more than half the days," and "nearly every day," respectively). Total scores range from 0-21 with cut-off points of 5, 10 and 15 representing mild, moderate and severe anxiety, respectively. | Baseline and 12 months post-enrollment |
| Change from baseline in self-reported depressive symptoms, as measured by the Patient Health Questionnaire - 9, at 12-months post-study enrollment | Patient Health Questionnaire-9 (PHQ-9): The PHQ-9 will be used to evaluate depressive symptoms. This 9-item scale assesses the frequency of depressive symptoms experienced over the past two weeks. | Baseline and 12 months post-enrollment |
| Change from baseline in self-reported sleep problems, as measured by the Insomnia Severity Index, at 12-months post-study enrollment | Insomnia Severity Index (ISI): The ISI is a 7-item self-report questionnaire that evaluates the severity of initial insomnia, sleep maintenance problems, terminal insomnia, satisfaction with sleep patterns, interference with daily functioning, impairment attributed to sleep problems and level of distress caused by sleep problems. It uses a 5-point Likert scale (0 = not at all; 4 = extremely), total scores range from 0 to 28, with high scores indicating greater insomnia severity. | Baseline and 12 months post-enrollment |
| Change from baseline in risk for opioid abuse, as measured by the Screener and Opioid Assessment for Patients with Pain, at 12-months post-study enrollment | Screener and Opioid Assessment for Patients with Pain (SOAPP): The SOAPP is a 24-item questionnaire used to evaluate the risk for opioid abuse in patients with chronic pain who are being considered for long-term opioid therapy. A consensus of 26 pain and addiction experts was obtained in order to determine the important characteristics of patients with chronic pain that can predict medication misuse. Fourteen of the 24 SOAPP items predict future aberrancies. | Baseline and 12 months post-enrollment |
| Change from baseline in self-reported traumatic stress, as measured by the PTSD Checklist for DSM - 5, at 12-months post-study enrollment | PTSD Checklist for DSM - 5 (PCL-5): The PCL-5 is a self-report questionnaire that assesses symptoms for post-traumatic stress disorder (PTSD). It is used as a measure of the 20 symptoms of PTSD that are mentioned in the Diagnostic and Statistical Manual of Mental Disorders - fifth edition (DSM-V) and has been validated. Each item on the questionnaire is rated on a scale of 0 to 4, representing answers of "not at all," "a little bit," "moderately," "quite a bit," and "extremely," respectively. Total scores range from 0-80 with a cut-off point of 38 suggesting endorsement of PTSD. | Baseline and 12 months post-enrollment |
| Change from baseline in self-reported quality of life, as measured by The Quality of Life Questionnaire EuroQol, at 12-months post-study enrollment | The Quality of Life Questionnaire EuroQol (EQ-5D): The EQ-5D is a simple-to-use, valid, and sensitive instrument measuring quality of life. It covers 5 dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has 3 levels: no problems, some problems, or severe problems and participants use a tick box to select the statement that is most representative of their conditions. Participants are also asked to rate, using a visual analogue scale (0 to 100), their state of health. | Baseline and 12 months post-enrollment |
