Abstract

BackgroundThe present study was conducted to examine the reliability and validity of the ‘Korean Standard Pattern Identification for Stroke (K-SPI-Stroke)’, which was developed and evaluated within the context of traditional Korean medicine (TKM).MethodsBetween September 2006 and December 2010, 2,905 patients from 11 Korean medical hospitals were asked to complete the K-SPI-Stroke questionnaire as a part of project ' Fundamental study for the standardization and objectification of pattern identification in traditional Korean medicine for stroke (SOPI-Stroke). Each patient was independently diagnosed by two TKM physicians from the same site according to one of four patterns, as suggested by the Korea Institute of Oriental Medicine: 1) a Qi deficiency pattern, 2) a Dampness-phlegm pattern, 3) a Yin deficiency pattern, or 4) a Fire-heat pattern. We estimated the internal consistency using Cronbach’s α coefficient, the discriminant validity using the means score of patterns, and the predictive validity using the classification accuracy of the K-SPI-Stroke questionnaire.ResultsThe K-SPI-Stroke questionnaire had satisfactory internal consistency (α = 0.700) and validity, with significant differences in the mean of scores among the four patterns. The overall classification accuracy of this questionnaire was 65.2 %.ConclusionThese results suggest that the K-SPI-Stroke questionnaire is a reliable and valid instrument for estimating the severity of the four patterns.

Highlights

The present study was conducted to examine the reliability and validity of the ‘Korean Standard Pattern Identification for Stroke (K-SPI-Stroke)’, which was developed and evaluated within the context of traditional Korean medicine (TKM)
Other medical systems did not recognize the pattern classifications of TKM as a diagnostic system by TKM doctors, which prompted these doctors to study whether they could make the same diagnosis in identical patients and whether their diagnoses were accurate
Patients with diabetes and hyperlipidemia accounted for 26.73% and 12.63% of the population, respectively

Summary

Introduction

The present study was conducted to examine the reliability and validity of the ‘Korean Standard Pattern Identification for Stroke (K-SPI-Stroke)’, which was developed and evaluated within the context of traditional Korean medicine (TKM). Traditional Korean medicine (TKM), which considers- the location, cause, and nature of patients’ diseases, has been the major treatment modality in the Korean medical system for properly treating stroke patients. PI is a process of the overall analysis of clinical data using an integrative approach that addresses the etiology, pathology, and treatment method [2]. This diagnostic system is theoretically well organized and involves the classification of patients into certain categories. Considering the importance of PI in determining treatment regimens, an accurate questionnaire is warranted
