SA2 - Prevalence of Psychiatric Illnesses in Patients Undergoing Oral and Maxillofacial Surgery Procedures in an Outpatient Setting

Abstract: Mental illness is highly prevalent among adults in the United States, with almost 1 in 5 adults living with some degree of mental illness. Given most of oral and maxillofacial surgery (OMS) procedures are inherently anxiety-generating, the authors sought to determine the burden of psychiatric illness in the population seeking care at an outpatient OMS unit of the University of Cincinnati. The authors hypothesized that psychiatric diagnoses would be common in this population.
This is an ongoing retrospective cohort study. Study subjects were identified by searching CPT codes through electronic health records to identify all patients older than 15 years of age who underwent any oral and maxillofacial surgery outpatient procedure in 2018 (January 1 to December 21). Data on demographics, ASA status, presence of psychiatric diagnosis according to DSM-5, type of procedure, and complications were collected by performing a retrospective chart review. A total of 4616 patients were identified for the chosen timeframe. All the duplicates (387 patients) were removed; 252 patients were further removed as they did not meet the inclusion criteria (no procedure performed, < 15 years old). That left a dataset of 3977 patients. So far, complete data extraction has been conducted for 1300 patients who were chosen randomly. Data extraction was conducted by 5 students who were all trained on the procedures for data extraction.
Descriptive analysis was conducted and prevalence rates were calculated. Out of total of 1300 patients who were reviewed, 60.9% (792) were females and 39.1% (508) were males. Age range was from 15 to 98 years with a mean age of 34.2 years; 45.2% (588) were Caucasian, 39% (507) were African-American, 0.7% (9) were Asian, 3.1% (40) were Hispanic, 3.3% (43) were other races, and 8.7% (113) were of unknown race; 32.1% (418) of patients were classified as ASA I, 55.6% (723) were ASA II, 11.2% (145) were ASA 3, and 1.1% (14) were ASA IV. Among the total reviewed population through OMS vision, 305 patients were found to have reported psychiatric diagnosis. Further review of medical history of the remaining patients was performed through Epic, and 26 more patients were found to have reported psychiatric diagnosis. A total of 25.5% (331) of patients were found to have a pre-existing psychiatric diagnosis. Out of these patients, 62 had neurogenic disorders, 29 had schizophrenia spectrum disorders, 56 had bipolar disorders, 218 had anxiety and depressive disorders, 82 had substance use and addictive disorders, 5 had personality disorders, and 7 had other disorders. A total of 102 patients had multiple psychiatric diagnosis. Among the 1300 procedures completed, 11.8% (153) of patients experienced postoperative complications and, among these, 24.9% (38) had psychiatric diagnoses.
The review shows that psychiatric illnesses are common among the oral and maxillofacial surgery population. This population is also likely to have more complications. The ongoing record review would shed more light in this arena when complete. Prognostic implications of preoperative psychiatric disorders on surgical outcome should be demonstrated prospectively in intervention studies.
