Despite the urgent need to control dementia, an effective treatment has yet to be developed. Along with the Korean government's policy of cooperation between conventional medicine (CM) and Korean medicine (KM), integrative medical services for dementia patients are being provided. This study aimed to compare the integrative medical clinic (IMC) for dementia used by Dongguk University Hospitals (DUH) with other service models and to review the characteristics and treatment outcomes of patients who had visited DUH over the past 5 years. Patients' electronic medical records from May 2015 to June 2020 were searched and their data were analyzed to evaluate the IMC's service model. Patient demographic and clinical characteristics, diagnostic tests, and treatment patterns for CM and KM were collected. The proportion of patients who did not show worsening cognitive function was described in detail. A strength of the DUH integrative medicine clinic is its ability to manage both KM and CM patients in the same space at the same time. Among the 82 patients who visited the clinic during our study period, 56 remained for data analysis after we excluded patients who met the exclusion criteria; nineteen patients had diagnoses of mild cognitive impairment. Among collaboration patterns, the first visit to the IMC had the highest proportion (55.4%). Among diagnosed tests in CM, laboratory tests and neuropsychological tests were used the most. In KM, a heart rate variability test was frequently used. The most common CM treatment prescribed was anticonvulsants, with 22 patients (39.2%) receiving donepezil, whereas the most frequent KM treatments were acupuncture (82.1%) and herbal medicine (78.6%). Twelve patients were followed up with the Mini-Mental State Examination, and 8 demonstrated either no worsening or improved cognition (baseline Mini-Mental State Examination range: 21-26). All 8 patients had mild cognitive impairment including 6 with amnestic, multidomain impairment. This study searched for a way to improve cognitive dysfunction and dementia using an integrative approach, and it shows promising results for mild cognitive impairment. However, more precisely designed follow-up studies are needed to address the present work's limitations of a retrospective study design and a small sample size.
