Abstract

INTRODUCTION:

Little is known about what constitutes appropriate diagnostic testing in patients with distal symmetric polyneuropathy (DSP).

METHODS:

Utilizing an ICD-9 screening method and medical record abstraction, we determined the number of new cases of DSP within community neurology practices in Nueces County, Texas. We then compared 2 case capture methods (ICD-9 vs. all-case review screening).

RESULTS:

The ICD-9 case capture method identified 52 cases over a 3-month period. Comparing case capture methods, the ICD-9 method identified 16 of 17 cases identified by the all-case review method (94%). The ICD-9 method required screening of 84% fewer charts compared with the all-case review.

CONCLUSIONS:

Many new cases of DSP occur each month within Nueces County. The ICD-9 screening technique combined with medical abstraction is an efficient method to identify new DSP cases in this community. These findings are critical for future epidemiological investigations into patients with DSP.
