Telehealth Outreach for Chronic Back Pain (TELE)

Descrizione dettagliata
Chronic low back pain (CLBP) is a major medical problem for the VA, affecting up to 15% of all veterans in primary care. Furthermore, prior surveys indicate CLBP is a leading cause of medical discharge of active duty personnel, and of medical disability costs. Given current demands on military personnel it is likely the burden of chronic pain will increase. The VA has adopted the Agency for Health Care Policy and Research Guidelines for evaluation of back pain but these guidelines do not provide specifics for true rehabilitation. It is acknowledged that most back pain patients are not surgical candidates, that medications provide only limited analgesia, and that symptom control and improved function require a comprehensive approach addressing the cognitive, affective, and behavioral aspects of chronic pain. Fortunately, structured, specific interventions to both address the multidimensional nature of pain and operationalize treatment principles in primary care settings are available. These interventions, which reflect the VA emphasis on patient-centered care, can be effective in reducing disability and pain, but are a frequently overlooked component of effective care. One reason is that most clinics lack appropriately trained psychologists. Moreover, even when specialists are available, the prevailing clinic-based service model is either too resource-intensive, or presents barriers to access.
One approach to addressing some these barriers is the use of "telehealth" outreach. Studies in diverse medical disorders and some chronic pain syndromes suggest that care can be delivered efficiently and effectively with minimal therapist contact in home-based treatment models, using telephone consultation to replace clinic visits. These approaches are fully congruent with recent VA telehealth initiatives to improve access and cost efficiency. In VA Pain Clinic settings our face-to-face, 8-week, 8-hours contact time Cognitive Behavioral Self-Management Skills Training (CBSST) program appears to be effective in reducing disability and pain, and improving mood in chronic back pain. Given the scarcity of specialized psychologists, a second approach is to train non-specialists (eg, primary care medical nurse personnel) instead of psychologists to deliver treatment, to help improve access to the intervention.
We conducted two double blind, randomized assignment, two-arm, parallel groups, six-month clinical trials. Patients with CLBP were recruited from VA San Diego primary care clinics and the community. Participants received either CBSST or Rogerian Psychotherapy in a home-based, telephone- delivered format for a total of 10 hours of therapist contact time. The methodological difference between the two studies was the discipline of the interventionist. In Study 1 the intervention was delivered by a psychologist with specific training in cognitive behavioral therapy; in Study 2 the intervention was was done by a medical primary care nurse who had been trained to deliver a version of CBSST modified to be suitable for delivery by an individual without specific expertise in cognitive behavioral therapy. The control condition was a supportive psychotherapy, again suitably modified in the case of the medical nurse interventionist. Assessments were conducted at baseline and at end of treatment, and at one, three and six months post-treatment. The primary data analytic strategy was an intent-to-treat analysis (last observation carried forward) of all participants as randomized. The primary end point was physical function (Roland & Morris Disability) at end of 8-week treatment; secondary end points were pain intensity (Numeric Rating Scale) and patient-reported clinical global impression of change. The aim of the research was to develop more accessible and more cost-efficient back pain treatment.

Descrizione
Inclusion Criteria:
- Ages 18-75 inclusive;
- chronic musculoskeletal low back pain (pain "on a daily basis" for at least six months) as the primary pain problem;
- not eligible for back surgery;
- presently lives in the San Diego area and will do so six months after baseline examination;
- English-speaking, literate, with stable residence and phone.
Exclusion Criteria:
- Major medical illness (e.g., insulin-dependent diabetes mellitus with neuropathy or "poor control", heart disease with New York Heart Association Functional Class III or IV, or chronic obstructive pulmonary disease requiring supplemental oxygen which might confound effects of pain on function);
- candidate for spine surgery;
- back pain associated with pregnancy, rheumatoid arthritis, neoplastic disease, osteomyelitis, or neural arch lesions, since their treatment and prognosis differs from the usual back pain population, or spinal stenosis, since increased physical activity would be contraindicated;
- history of Diagnostic and Statistical Manual (DSM)-IV bipolar disorder, dementia, or schizophrenia;
- current active DSM-IV diagnosed alcohol or non-prescribed substance dependence;
- current active DSM-IV major depressive episode or post-traumatic stress disorder since specialty mental health care would be indicated;
- non-opioid and opioid analgesics are permitted, except we will exclude patients on a hospital-initiated opioid treatment "contract," since at this medical center "contracting" identifies patients with history of opioid diversion, multiple VA and non-VA opioid prescribers, and repeated dose escalation in the absence of evidence of disease progression.

Misura Descrizione |
Lasso di tempo |
---|---|---|
Roland and Morris Disability Questionnaire Psychologist-Delivered Treatment Study
Lasso di tempo: Baseline, End of Treatment (8 weeks)
|
The Roland and Morris is a 24-item self-report measure of interference of back pain on everyday function at the present time.
Each item is qualified by the phrase "because of my back pain" (e.g., "Because of my back I walk more slowly than usual . . .
; Because of my back I lie down to rest more often").
Scoring the measure involves summing the number of items endorsed (from 0 to 24).
Lower scores indicate less disability.

Patient-rated Global Clinical Impression of Percent Change in Overall Pain and Function
Lasso di tempo: End of Treatment (8 weeks)
|
Participant rating of overall improvement compared to baseline in terms of back pain impact on everyday function, self-categorized as "Better," "Worse," or "About the Same."
Participants then were asked to estimate the percentage of change (i.e., 0 to 100%).
Participants rating themselves as "About the Same" were coded as "0%" change.
The percentage of change was calculated for each Group as a whole (Cognitive Behavioral Therapy-Psychologist Delivered compared to Supportive Care Psychologist-Delivered).

Percentage of Participants Rating Global Impression of Change as 'Much Improved' or 'Very Much Improved'
Lasso di tempo: End of Treatment (8 weeks)

Participant self-rating of overall change compared to baseline, considering overall function and pain intensity, using a 7-point scale ranging from 'Very Much Worse' to 'Very Much Improved.'
We compared the proportion of participants in each Group rating themselves as either 'Much Improved' or 'Very Much Improved.'
