DECISION AND ORDER
This case is decided pursuant to Chapter 410 of the Texas Workers’ Compensation Act and Rules of the Division of Workers’ Compensation adopted thereunder.
ISSUES
A contested case hearing was held on October 23, 2009 to decide the following disputed issue:
Is the preponderance of the evidence contrary to the decision of the IRO that Claimant is not entitled to bilateral SI joint injections for the compensable injury of ______________?
PARTIES PRESENT
Claimant appeared and was assisted by WB, ombudsman. Carrier appeared and was represented by KP, attorney.
BACKGROUND INFORMATION
Claimant is a 43-year-old former assembly line worker for Employer who fell at work on ______________, injuring her left shoulder and arm and low back. Claimant complains of continuing low back pain for which she has been prescribed medications by her family doctor over the years. An MRI on April 22, 2009 showed a degenerated disc at L5-S1 with a 3 mm central protrusion. On June 18, 2009, she had consultation with Dr. P, M.D. at (Healthcare Provider), who proposed the disputed SI joint injections bilaterally. Dr. P has only seen Claimant one time.
DISCUSSION
Texas Labor Code Section 408.021 provides that an employee who sustains a compensable injury is entitled to all health care reasonably required by the nature of the injury as and when needed. Health care reasonably required is further defined in Texas Labor Code Section 401.011 (22a) as health care that is clinically appropriate and considered effective for the injured employee’s injury and provided in accordance with best practices consistent with evidence based medicine or, if evidence based medicine is not available, then generally accepted standards of medical practice recognized in the medical community. Health care under the Texas Workers’ Compensation system must be consistent with evidence based medicine if that evidence is available. Evidence based medicine is further defined in Texas Labor Code Section 401.011 (18a) to be the use of the current best quality scientific and medical evidence formulated from credible scientific studies, including peer-reviewed medical literature and other current scientifically based texts and treatment and practice guidelines. The Commissioner of the Division of Workers’ compensation is required to adopt treatment guidelines that are evidence-based, scientifically valid, outcome-focused and designed to reduce excessive or inappropriate medical care while safeguarding necessary medical care. Texas Labor Code Section 413.011(e). Medical services consistent with the medical policies and fee guidelines adopted by the commissioner are presumed reasonable in accordance with Texas Labor Code Section 413.017(1).
In accordance with the above statutory guidance, the Division of Workers’ Compensation has adopted treatment guidelines by Division Rule 137.100. This rule directs health care providers to provide treatment in accordance with the current edition of the Official Disability Guidelines (ODG), and such treatment is presumed to be health care reasonably required as defined in the Texas Labor Code. Thus, the focus of any health care dispute starts with the health care set out in the ODG. Also, in accordance with Division Rule 133.308 (t), “A decision issued by an IRO is not considered an agency decision and neither the Department nor the Division are considered parties to an appeal. In a Contested Case Hearing (CCH), the party appealing the IRO decision has the burden of overcoming the decision issued by an IRO by a preponderance of evidence-based medical evidence.”
With regard to the proposed treatment, the ODG provides as follows:
Sacroiliac joint injections (SJI)
Recommended as an option if failed at least 4-6 weeks of aggressive conservative therapy. See the Hip & Pelvis Chapter for more information, references, and ODG Criteria for the use of sacroiliac blocks.
Sacroiliac joint blocks
Recommended as an option if failed at least 4-6 weeks of aggressive conservative therapy as indicated below. Sacroiliac dysfunction is poorly defined and the diagnosis is often difficult to make due to the presence of other low back pathology (including spinal stenosis and facet arthropathy). The diagnosis is also difficult to make as pain symptoms may depend on the region of the SI joint that is involved (anterior, posterior, and/or extra-articular ligaments). Pain may radiate into the buttock, groin and entire ipsilateral lower limb, although if pain is present above L5, it is not thought to be from the SI joint.
Innervation: The anterior portion is thought to be innervated by the posterior rami of the L1-S2 roots and the posterior portion by the posterior rami of L4-S3.although the actual innervation remains unclear. Anterior innervation may also be supplied by the obturator nerve, superior gluteal nerve and/or lumbosacral trunk. (Vallejo, 2006) Other research supports innervation by the S1 and S2 sacral dorsal rami.
Etiology: includes degenerative joint disease, joint laxity, and trauma (such as a fall to the buttock). The main cause is SI joint disruption from significant pelvic trauma.
Diagnosis: Specific tests for motion palpation and pain provocation have been described for SI joint dysfunction: Cranial Shear Test; Extension Test; Flamingo Test; Fortin Finger Test; Gaenslen’s Test; Gillet’s Test (One Legged-Stork Test); Patrick’s Test (FABER); Pelvic Compression Test; Pelvic Distraction Test; Pelvic Rock Test; Resisted Abduction Test (REAB); Sacroiliac Shear Test; Standing Flexion Test; Seated Flexion Test; Thigh Thrust Test (POSH). Imaging studies are not helpful. It has been questioned as to whether SI joint blocks are the “diagnostic gold standard.” The block is felt to show low sensitivity, and discordance has been noted between two consecutive blocks (questioning validity). (Schwarzer, 1995) There is also concern that pain relief from diagnostic blocks may be confounded by infiltration of extra-articular ligaments, adjacent muscles, or sheaths of the nerve roots themselves. Sacral lateral branch injections have demonstrated a lack of diagnostic power and area not endorsed for this purpose. (Yin, 2003)
Treatment: There is limited research suggesting therapeutic blocks offer long-term effect. There should be evidence of a trial of aggressive conservative treatment (at least six weeks of a comprehensive exercise program, local icing, mobilization/manipulation and anti-inflammatories) as well as evidence of a clinical picture that is suggestive of sacroiliac injury and/or disease prior to a first SI joint block. If helpful, the blocks may be repeated; however, the frequency of these injections should be limited with attention placed on the comprehensive exercise program. (Forst, 2006) (Berthelot, 2006) (van der Wurff, 2006) (Laslett, 2005) (Zelle, 2005) (McKenzie-Brown 2005) (Pekkafahli, 2003) (Manchikanti, 2003) (Slipman, 2001) (Nelemans-Cochrane, 2000) See also Intra-articular steroid hip injection; & Sacroiliac joint radiofrequency neurotomy.
Criteria for the use of sacroiliac blocks:
- The history and physical should suggest the diagnosis (with documentation of at least 3 positive exam findings as listed above).
- Diagnostic evaluation must first address any other possible pain generators.
- The patient has had and failed at least 4-6 weeks of aggressive conservative therapy including PT, home exercise and medication management.
- Blocks are performed under fluoroscopy. (Hansen, 2003)
- A positive diagnostic response is recorded as 80% for the duration of the local anesthetic. If the first block is not positive, a second diagnostic block is not performed.
- If steroids are injected during the initial injection, the duration of pain relief should be at least 6 weeks with at least > 70% pain relief recorded for this period.
- In the treatment or therapeutic phase (after the stabilization is completed), the suggested frequency for repeat blocks is 2 months or longer between each injection, provided that at least >70% pain relief is obtained for 6 weeks.
- The block is not to be performed on the same day as a lumbar epidural steroid injection (ESI), transforaminal ESI, facet joint injection or medial branch block.
- In the treatment or therapeutic phase, the interventional procedures should be repeated only as necessary judging by the medical necessity criteria, and these should be limited to a maximum of 4 times for local anesthetic and steroid blocks over a period of 1 year.
The first utilization reviewer, a board certified physical medicine and rehabilitation specialist, cited the ODG section set out in this decision and stated that Dr. P lists findings inconsistent with neurological deficits or radicular symptoms. Upon reconsideration by another board certified physical medicine and rehabilitation specialist, the reviewer stated that radiographs were suggestive of facet disease at L4-5 which may be the pain generator. He further stated that pain upon flexion and extension may be consistent with another diagnosis. The IRO reviewer was a board certified specialist in physical medicine and rehabilitation with an additional certification in pain management. This reviewer concluded that Claimant had only one of the listed signs for SI joint dysfunction, that she had not completed the described therapy program, and that the proposed treatment did not meet the ODG guidelines for bilateral SI joint injections.
Dr. P wrote a letter of reply to the IRO asserting that he had found three positive findings listed in the ODG for SI joint dysfunction. However, he failed to show that the aggressive conservative therapy program had been completed, and that the other pain generators had been ruled out. Dr. O reviewed Claimant’s records of treatment and pointed out x-ray evidence of facet disease and degenerative end-plate findings, which would mitigate against the role of SI joint as a pain generator. Claimant failed to offer evidence based medicine to contradict the IRO. The preponderance of the evidence is not contrary to the decision of the IRO upholding denial of the proposed SI injections.
Even though all the evidence presented was not discussed, it was considered. The Findings of Fact and Conclusions of Law are based on all of the evidence presented.
