Explosive growth of facet joint interventions in the medicare population in the United States: a comparative evaluation of 1997, 2002, and 2006 data

<p>Abstract</p> <p>Background</p> <p>The Office of Inspector General of the Department of Health and Human Services (OIG-DHHS) issued a report which showed explosive growth and also raised questions of lack of medical necessity and/or indications for facet joint injection services in 2006.</p> <p>The purpose of the study was to determine trends of frequency and cost of facet joint interventions in managing spinal pain.</p> <p>Methods</p> <p>This analysis was performed to determine trends of frequency and cost of facet joint</p> <p>Interventions in managing spinal pain, utilizing the annual 5% national sample of the Centers for</p> <p>Medicare and Medicaid Services (CMS) for 1997, 2002, and 2006.</p> <p>Outcome measures included overall characteristics of Medicare beneficiaries receiving facet joint interventions, utilization of facet joint interventions by place of service, by specialty, reimbursement characteristics, and other variables.</p> <p>Results</p> <p>From 1997 to 2006, the number of patients receiving facet joint interventions per 100,000</p> <p>Medicare population increased 386%, facet joint visits increased 446%, and facet joint interventions increased 543%. The increases were higher in patients aged less than 65 years compared to those 65 or older with patients increasing 504% vs. 355%, visits increasing 587% vs. 404%, and services increasing 683% vs. 498%.</p> <p>Total expenditures for facet joint interventions in the Medicare population increased from over $229 million in 2002 to over$511 million in 2006, with an overall increase of 123%. In 2006, there was a 26.8-fold difference in utilization of facet joint intervention services in Florida compared to the state with the lowest utilization - Hawaii.</p> <p>There was an annual increase of 277.3% in the utilization of facet joint interventions by general physicians, whereas a 99.5% annual increase was seen for nurse practitioners (NPs) and certified registered nurse anesthetists (CRNAs) from 2002 to 2006. Further, in Florida, 47% of facet joint interventions were performed by general physicians.</p> <p>Conclusions</p> <p>The reported explosive growth of facet joint interventions in managing spinal pain in certain regions and by certain specialties may result in increased regulations and scrutiny with reduced access.</p

Refill Port Identification of Intrathecal Drug Delivery System Devices With a Raised Fill Port

Objectives The aim of this study was to assess the accuracy of the manual identification of the reservoir fill port (RFP) for refill of intrathecal drug delivery systems (IDDSs) with a raised RFP on the pump surface (raised-RFP-IDDSs), and compare this to previously reported data of patients with IDDSs with a recessed RFP (recessed-RFP-IDDSs). Methods Nineteen patients underwent 2 IDDS refills for the treatment of noncancer pain or spasticity. The primary endpoint of this prospective observational study was the deviation between the needle insertion point and the RFP center, quantified by fluoroscopic visualization. A distance surpassing that between the center and the margin of the RFP of 4 mm was considered a clinically relevant deviation. The results were compared with previously reported data of a patient cohort with recessed-RFP-IDDSs, and the differences were tested using Student's t-test. Results The mean deviation from the RFP center was 4.9 mm (standard deviation = 3.7). The RFP identification accuracy deviated more than the clinically relevant difference in 17 out of 35 instances (48.6%). The number of attempts and median procedural time was significantly correlated to the needle deviation. The mean deviations in the raised-RFP-IDDS cohort were consistently lower compared to the recessed-RFP-IDDS cohort (first refill procedure 4.0 vs. 8.5, P <0.001; second procedure 5.9 vs. 8.1, P = 0.074). Conclusion The results of this study suggest that the manual localization of the RFP for raised-RFP-IDDSs is moderately accurate, and more accurate if compared to previously published accuracy of the template-guided technique for recessed-RFP-IDDSs

Lumbar Radiofrequency Ablation Interfering With S1 Dorsal Root Ganglion Stimulation Systems: Experience From Two Cases

© 2020 World Institute of Pain Background: Dorsal root ganglion stimulation (DRG-S) has emerged as a treatment for complex regional pain syndrome (CRPS) of the lower extremities, and recent small studies are demonstrating its potential efficacy in pain syndromes that are traditionally considered nociceptive in nature, such as axial low back pain. While improvements in neuromodulation technology have been substantial over the past decade, with DRG-S systems patients occasionally require additional interventional pain treatments for treatment of pain from other sources. Radiofrequency ablation (RFA) of medial branch nerves innervating the facet joints is an accepted therapy for pain arising from the facet joints. Methods: We describe 2 cases from the same practice where we observed similar phenomena while performing a 2-needle monopolar lumbar RFA in patients with a DRG-S system implanted with leads positioned bilaterally at the S1 DRGs. Results: Initiation of RFA resulted in motor activation and discomfort in an S1 distribution in the legs in both individual cases. Conclusions: RFA can interfere with implanted DRG-S systems, resulting in overstimulation with motor recruitment. Specific anatomical considerations and device settings that may prevent interference are discussed

Carpal tunnel syndrome in the elderly: nerve conduction parameters Síndrome do túnel do carpo em idosos: parâmetros de condução nervosa

OBJECTIVE: To establish nerve conduction parameters for carpal tunnel syndrome (CTS) electrodiagnosis in the elderly. METHOD: Thirty healthy subjects (65-86 years), 9 male and 21 female, were studied. Routine median and ulnar sensory and motor nerve conduction studies, median mixed palmar latency, comparative latency techniques median to ulnar (sensory, mixed and motor lumbrical-interossei), median to radial (sensory), and combined sensory index (CSI) were performed in both hands. RESULTS: The upper limits of normality (97.5%) were: median sensory distal latency 3.80 ms (14 cm); median motor distal latency 4.30 ms (8 cm); median palmar latency 2.45 ms (8 cm); lumbrical-interossei latency difference 0.60 ms (8 cm); comparative median to radial 0.95 ms (10 cm); comparative median to ulnar 0.95 ms (14 cm); comparative palmar median to ulnar 0.50 ms (8 cm); and CSI 2.20 ms. Sensory and mixed latencies were measured at peak. CONCLUSION: Our results establish new nerve conduction parameters for mild CTS electrodiagnosis in the elderly and will be helpful to reduce the number of false positive cases in this age.<br>OBJETIVO: Estabelecer parâmetros de condução nervosa para o eletrodiagnóstico da síndrome do túnel do carpo (STC) em idosos. MÉTODO: Foram estudadas 30 pessoas idosas (65-86 anos) saudáveis. Foi realizado estudo de condução nervosa sensitiva e motora rotineira dos nervos mediano e ulnar, latência palmar mista do mediano, técnicas de comparação de latências mediano-ulnar (sensitivo, misto e motor lumbrical-interósseo) e mediano-radial (sensitivo) e índice sensitivo combinado (ISC) em ambas as mãos. RESULTADOS: Os limites superiores de normalidade, 97,5% foram: latência distal sensitiva do mediano 3,80 ms (14 cm); latência distal motora do mediano 4,30 ms (8 cm), latência palmar do mediano 2,45 ms (8 cm), diferença de latência lumbrical-interósseo 0,60 ms (8 cm), comparação mediano-radial 0,95 ms (10 cm), comparação mediano-ulnar 0,95 ms (14 cm), comparação mediano-ulnar palmar 0,50 ms (8 cm) e ISC 2,20 ms. As latências sensitivas e mistas foram medidas no pico. CONCLUSÃO: Nossos resultados estabelecem novos valores de condução nervosa para o eletrodiagnóstico da STC leve em idosos
