Anxiety and Depression in an Internal Medicine Resident Continuity Clinic: Difficult Diagnoses

Objective: To determine the prevalence of anxiety and depression in a residents' clinic and if these diagnoses are associated with patients being perceived as difficult, as well as how often these diagnoses are documented in the patients' charts. Methods: This was a cross-sectional study conducted in a general internal medicine residents' clinic. A total of 135 patients were given the Primary Care Evaluation of Mental Disorders questionnaire (DSM-IIIR version) and their physicians filled out the Difficult Doctor-Patient Relationship Questionnaire after the visit. Charts were reviewed for documentation of a diagnosis of anxiety or depression. Results: Major depression was present in 26 percent, dysthymia 16 percent, major depression in partial remission 9 percent, generalized anxiety disorder 13 percent, and panic disorder 7 percent. Overall, 38 percent had at least one and 21 percent had more than one diagnosis. Of patients with one psychiatric diagnosis, 9 percent were classified as difficult versus 100 percent of patients with four diagnoses. Documentation of depression was noted for 43 percent of patients with major depression but only 9 percent with an anxiety disorder. Conclusions: Anxiety and depression were very common among the patients in this clinic, and increasing numbers of diagnoses were associated with patients being classified as difficult. Residents diagnosed depressive disorders as often as practicing physicians in other studies, but anxiety less well. The high prevalence of mental disorders has implications for resident education in that they need to be prepared to care for these patients, but residents also may benefit from exposure to sites with more typical prevalences of these illnesses.
