First, do no harm by adopting evidence-based policy initiatives: the overselling of ICD-10 by congress with high expectations.

While it appears to be beneficial to apply a detailed disease classification system, the costs, cash flow disruptions, and increased investments with physician time incorporated into learning these processes, patient care might unfortunately suffer. This is essentially an unfunded mandate with much of the burden of transitioning to ICD-10 falling on health care providers,especially small independent practices. This will impact interventional pain management practices substantially.Further, as we have shown in previous manuscripts,the so-called advantages of multiple codes with specificity and granularity does not translate into reality where some specificity is actually lost for various codes. As Grimsley and O'Shea (1) have described in clinical practices, doctors do not treat codes, but they treat patients according to the individual clinical condition.A doctor will be losing valuable time and also will not be able to obtain meaningful information due to burdensome regulations of meaningful use, PQRS,value-based reimbursement, electronic prescribing,and now a major impact with change to ICD-10. Thus,very little benefit will be seen by practitioners, which cannot be said for the health care information industry.With overwhelming regulatory atmosphere created by numerous federal regulations and those including under the Affordable Care Act (15), there is no evidence that ICD-10 is needed, there is no evidence that it will be effective, and, finally, there is preponderance of evidence of adverse consequences. Thus, Congress should be cautious in imposing further regulations on already strained independent practices with ongoing regulations and imposing yet another unfunded mandate on the medical profession.

An updated assessment of utilization of interventional pain management techniques in the Medicare population: 2000 - 2013.

BACKGROUND: The rapid increase in the prevalence of chronic pain and disability, and the explosion of interventional pain management associated health care costs are a major concern for our community. Further, the increasing utilization of numerous modalities of treatments in managing chronic pain, continue to escalate at a pace which may not be sustainable. There are multiple regulations in place to control the growth of health care expenditures which seem to have been largely ineffective. Among the various modalities utilized in managing chronic pain, interventional techniques have shown a significant increase in their utilization in the face of continued debate with respect to the accuracy of diagnostic interventions and the efficacy of therapeutic interventions. OBJECTIVE: To update and assess the utilization of interventional techniques in chronic pain management in fee-for-service Medicare population. STUDY DESIGN: An updated analysis of the growth of interventional techniques in managing chronic pain in fee-for-service Medicare beneficiaries from 2000 through 2013. METHODS: The data were derived and analyzed utilizing the Centers for Medicare and Medicaid Services (CMS) Physician Supplier Procedure Summary Master Data from 2000 through 2013. RESULTS: From 2000 through 2013, in fee-for-service Medicare beneficiaries, the overall utilization of interventional techniques services increased 236% at an annual average growth of 9.8%, whereas the per 100,000 Medicare population utilization increased 156% with an annual average growth of 7.5%. During this period, the US population increased 12% with an annual average increase of 0.9%, whereas those above 65 years of age increased 27% with an annual average increase of 1.9%. Total Medicare beneficiaries increased 31% with an annual average increase of 2.1%, with an overall increase of 64% for those above 65 years of age, an increase of 26%, constituting 17% of the US population in 2013. The overall increases in epidural and adhesiolysis procedures were 165% compared to 102% per 100,000 fee-for-service population with annual average increases of 7.8% and 5.6%. Facet joint and sacroiliac joint injections increased 417% for services with an annual average increase of 13.5%, whereas the rate per 100,000 fee-for-service Medicare beneficiaries increased 295% with an annual average increase of 11.1%. LIMITATIONS: Limitations of this assessment include the lack of inclusion of participants from Medicare Advantage plans, lack of appropriate available data for state-wide utilization, and potential errors in documentation, coding, and billing. CONCLUSION: This update once again shows a significant increase in interventional techniques in fee-for-service Medicare beneficiaries from 2000 through 2013 with an increase of 156% per 100,000 Medicare population with an annual average increase of 7.5%. During this period the Medicare population increased 31% with an annual average increase of 2.1%.

Transforaminal epidural injections in chronic lumbar disc herniation: a randomized, double-blind, active-control trial.

BACKGROUND: The estimated prevalence of lumbar radiculopathy has been described as 9.8 per 1,000 cases of low back pain. There are various surgical and nonsurgical modalities for treating lumbar disc herniation or radicular pain, including epidural injections. Epidural injection administration routes include transforaminal, interlaminar, and caudal approaches. The transforaminal approach requires the smallest volume to reach the primary site of pathology. Systematic reviews have yielded highly variable results, but a recent systematic review showed no significant difference among the 3 approaches. STUDY DESIGN: A randomized, controlled, double blind, active control trial. SETTING: An interventional pain management practice, a private specialty referral center in the United States. OBJECTIVES: To assess the effectiveness of transforaminal epidural injections of local anesthetic with or without steroids in managing chronic low back and lower extremity pain in patients with disc herniation and radiculitis. METHODS: One hundred twenty patients were randomly assigned to 2 groups: Group I received 1.5 mL of 1% preservative-free lidocaine, followed by 0.5 mL of sodium chloride solution. Group II received 1% lidocaine, followed by 3 mg, or 0.5 mL of betamethasone. The sodium chloride solution and betamethasone were either clear liquids or were provided in opaque-covered syringes. OUTCOMES ASSESSMENT: The primary outcome measure was significant improvement (at least 50%) measured by the average Numeric Rating Scale (NRS) and the Oswestry Disability Index 2.0 (ODI). Secondary outcome measures were employment status and opioid intake. RESULTS: At 2 years there was significant improvement in all participants in 65% who received local anesthetic alone and 57% who received local anesthetic and steroid. When separated into non-responsive and responsive categories based on initial relief of at least 3 weeks with 2 procedures, significant improvement (at least 50% improvement in pain and function) was seen in 80% in the local anesthetic group and 73% in the local anesthetic with steroid group. LIMITATIONS: Presumed limitations of this evaluation include the lack of a placebo group. CONCLUSION: Transforaminal epidural injections of local anesthetic with or without steroids might be an effective therapy for patients with disc herniation or radiculitis. The present evidence illustrates the lack of superiority of steroids compared with local anesthetic at 2-year follow-up.

A randomized, double-blind, active-control trial of the effectiveness of lumbar interlaminar epidural injections in disc herniation.

BACKGROUND: Among the multiple nonsurgical modalities, epidural injections are one of the most commonly utilized treatment modalities in managing chronic low back and lower extremity pain due to disc herniation and radiculitis. There is a paucity of randomized trials from contemporary interventional pain management settings utilizing fluoroscopy with long-term follow-up. STUDY DESIGN: Randomized, double-blind, active-controlled trial with 2-year follow-up. SETTING: An interventional pain management practice in the United States. OBJECTIVE: The objective was to assess the effectiveness of lumbar interlaminar epidural injections of local anesthetic with or without steroids for managing chronic low back pain of disc herniation or radiculitis. METHODS: Two groups of patients were studied, with 60 patients in each group receiving either local anesthetic only or local anesthetic mixed with betamethasone. OUTCOME MEASURES: The primary outcome measure was defined as pain relief and functional status improvement of 50%. The outcomes were assessed by numeric rating scale (NRS) of pain and functional status with Oswestry Disability Index (ODI). Secondary outcome measures included employment status and opioid intake. RESULTS: Results showed significant improvement in 60% of patients in Group I and 70% of patients in Group II at the end of 2 years. In addition, in the successful groups, those with at least 3 weeks of relief (with the first 2 procedures), the improvement was 72% in Group I and 71% in Group II. Results were somewhat superior for pain relief at 6 months and functional status at 12 months in the steroid group. Thus, the results indicate that a patient's failure to respond to local anesthetic alone, may be treated with addition of steroids. LIMITATIONS: The results of the study are limited by the lack of a placebo group. CONCLUSION: Lumbar interlaminar epidural injections of local anesthetic with or without steroids is an effective modality, in patients with chronic function limiting low back and lower extremity pain secondary to disc herniation after failure of conservative modalities.

Sustained attention in cranial dystonia patients treated with botulinum toxin.

BACKGROUND: Primary cranial dystonia (PCD) is related to a functional disorder in basal ganglia usually accompanied by impaired executive function. AIM: To investigate symptom relief and neurocognitive change in response to treatment with botulinum toxin (BTX) in a group of patients with PCD. METHODS: We assessed nine patients with PCD and nine age- and educationally matched healthy individuals using tests of memory, sustained attention, span of auditory attention, and perceptual flexibility. RESULTS: Despite well-preserved intellectual skills relative to controls, we identified a sustained attention deficit in patients with PCD. After BTX treatment, there was an increase in the scores of the concentration endurance test (sustained attention) and the values did not differ significantly from control group patients' scores. CONCLUSION: The results support the view that executive dysfunction in PCD is secondary to the disrupting effects of the symptoms. Treatment with BTX alleviates the symptoms and, consequently, improves sustained attention.

Enhancement of declarative memory associated with emotional content in a Brazilian sample.

Several studies have documented that emotional arousal may enhance long-term memory. This is an adaptation of a paradigm previously used in North American and European samples in investigations of the influence of emotion on long-term retention. A sample of 46 healthy adults of high and low educational levels watched a slide presentation of stories. A randomly assigned group watched a story with an arousing content and another group watched a neutral story. The stories were matched for structure and comprehensibility and the set and order of the 11 slides were the same in both conditions. Immediately after viewing the slide presentation, the participants were asked to rate the emotionality of the narrative. The arousing narrative was rated as being more emotional than the neutral narrative (t(44) = -3.6, P<0.001). Ten days later subjects were asked to remember the story and answer a multiple-choice questionnaire about it. The subjects who watched the arousing story had higher scores in the free recall measure (t(44) = -2.59, P<0. 01). There were no differences between groups in the multiple-choice test of recognition memory (t(44) = 0.26). These findings confirm that an emotional arousing content enhances long-term declarative memory and indicate the possibility of applying this instrument to clinical samples of various cultural backgrounds.

Thyroid function in very low birth weight infants: effects on neonatal hypothyroidism screening.

OBJECTIVES: To supply normative data for screening thyroxine (T4) and thyrotropin concentrations correlated with birth weight and age at screening of infants with birth weights ranging from 400 to 5500 gm, and to document the effects of screening of very low birth weight (VLBW) infants, because VLBW infants comprise 0.86% of surviving newborn infants and have very low total T4 concentrations with normal or elevated free T4 concentrations as a result of deficient protein binding of thyroid hormones. STUDY DESIGN: Both retrospective and prospective studies were used. We conducted retrospective analyses of screening of T4 and thyrotropin concentrations in 9,324 term, 18,946 low birth weight, and 3,450 VLBW infants in Massachusetts, and a prospective study of T4 and thyrotropin concentrations in 48 VLBW infants at 2 weeks of age. Forty of the infants also had hormone measurements at 4 weeks, 29 at 8 weeks of age, and 24 had analysis of cord blood samples. RESULTS: Median T4 concentrations for each weight group (in 250 gm increments) increased progressively and significantly up to 2500 gm. Of the surviving VLBW infants, 1.5% had screening T4 concentrations that were unmeasurably low (<3.9 nmol/L (0.3 microgram/dl)). The mean T4 concentration varied with age at screening, increasing from cord blood concentrations to a peak at 1 to 3 days of age and thereafter decreasing to a nadir at about 2 weeks in both low birth weight and VLBW infants. In VLBW infants the mean concentrations return to the level of 1 to 3 days by 4 to 8 weeks of age. The incidence of screening thyrotropin concentrations > or = 40 mU/L correlates inversely with weight. The incidence of early, transient hypothyroidism in VLBW infants defined by this thyrotropin concentration was eight times that in term infants. Two infants had late-onset, transient hypothyroidism at 2 and 7 weeks, respectively. CONCLUSIONS: The normative data related to birth weight and age at screening allow proper interpretation of VLBW results for primary T4 and primary thyrotropin screening programs. Screening of the concentrations of T4 and thyrotropin in VLBW increases the number of secondary measurements of T4 in a primary thyrotropin screening program and the number of secondary thyrotropin measurements in a primary T4 screening program by 6% and 9%, respectively. We recommend screening analyses for VLBW infants in the latter part of the first week of life and again at 2 and 4 to 6 weeks of age. This protocol would increase the number of screening analyses by 1.6%.
