Clinical Statistics of Dysphagia Rehabilitation Provided on Dental Visits to a Partner Hospital

Maintaining oral hygiene is an important yet often neglected aspect of rehabilitation medicine. Our visiting dental team, which provides dental treatments and swallowing rehabilitation, partnered with a medical hospital that had no dental department and began visiting and treating inpatients at this hospital. This study is aimed at evaluating the effects of dysphagia rehabilitation, and this was jointly conducted by medical and dental hospitals. The survey was conducted between May 2017 and March 2018. We retrospectively examined dysphagia rehabilitation provided to 25 patients (12 men and 13 women) aged 40-92 years (mean age: 77.1 ± 12.3 years). The largest number of requests for dental treatment was received from the internal medicine department (13 requests, 52.0%). A total of 39 videofluoroscopic or videoendoscopic examinations of swallowing interventions for dysphagia rehabilitation were conducted. All patients' oral and swallowing functions were evaluated using the functional oral intake scale (FOIS). At initial assessment, 9, 13, and 0 patients were at FOIS levels 1, 2, and 3 (use of tube feeding), respectively, and 1, 2, and 0 patients were at FOIS levels 4, 5, and 6 (only oral feeding), respectively. At the final assessment, 6, 10, and 4 patients were at FOIS levels 1, 2, and 3, respectively, and 0, 2, and 3 patients were at FOIS levels 4, 5, and 6, respectively. Oral and swallowing functions differed significantly between the first and final visits (p = 0.02). Visits conducted by a team of oral health practitioners to a medical hospital without a dental department appear to have a major impact and will become even more important in the future.
