The evaluation of distal symmetric polyneuropathy: utilisation and expenditures by community neurologists.

Authors Callaghan BC, Kerber KA, Banerjee M, Feldman EL, Morgenstern LB, Longoria R, Rodgers A, Longwell P, Lisabeth LD Submitted By Eva Feldman on 4/15/2016 Status Published Journal Journal of neurology, neurosurgery, and psychiatry Year 2016 Date Published Volume : Pages 87 : 113 - 4 PubMed Reference 25604430 Abstract Previous studies show that electrodiagnostic tests and MRIs are frequently ordered in the initial evaluation of neuropathy.1 ,2 However, American Academy of Neurology (AAN) guideline-supported tests, particularly the glucose tolerant test (GTT), are often omitted.1 Recent evidence suggests that electrodiagnostic studies and MRIs are the primary drivers of expenditures associated with neuropathy testing despite limited data to support their use.3 However, these results are based on Medicare claims; therefore, it remains unclear if this observation applies to other populations and when using a more rigorous case definition of neuropathy. Furthermore, Medicare claims do not provide detailed clinical information that would allow for investigation of patient-level factors associated with utilisation and expenditures. Our aim was to determine utilisation and expenditures in the evaluation of a new diagnosis of distal symmetric polyneuropathy (DSP) by community neurologists using a population-based design and a strict case definition. We also sought to determine which patient and physician factors were associated with testing expenditures, electrodiagnostic and MRI utilisation.
