Abstract

Objectives

This study is designed to statistically analyze the features of patients who visited to Department of Acupuncture and Moxibustion at OO Korean Medicine Hospital for 3 years.

Methods

This study retrospectively analyzed the medical records of patients at Department of Acupuncture and Moxibustion at OO Korean Medicine Hospital using IBM SPSS ver. 27.0 for Windows.

Results

  1. In the analysis of the total number of patients, those in their 30s accounted for the highest percentage, male patients had a higher rate.

  2. In the analysis of KCD-8 code, spinal stenosis and fractures in areas other than the spine were the most common in the 70s and older, and cervical sprains were the most common in other.

  3. In the analysis of the number of hospitalizations, patients classified as illness or higher age had more re-hospitalization than patients classified as injury or lower age in first-time care.

  4. In the analysis of hospitalization duration, patients classified as illness, female or higher age had longer hospitalization duration than patients classified as accident, male or lower age in first-time care.

Conclusion

We expect that the results of this study would be used as reference materials for analyzing medical consumption condition of Department of Acupuncture and Moxibustion.
