Depression but Not Anxiety Is a Significant Predictor of Physicians’ Assessments of Medical Status in Physically Ill Patients

Abstract

Background: In a cross-sectional study we investigated associations between self-ratings of anxiety and depression, physical factors and physicians’ assessments of patients’ medical status. Methods: Hospital inpatients (n = 574) consecutively admitted to internal medical wards were evaluated for the presence of anxiety and depressive symptoms using the Hospital Anxiety and Depression Scale (HADS). Physicians were asked for their perception of psychiatric problems in their patients and for their assessments of patients’ severity of illness, functional impairment and 1-year prognosis on 3-point ranking scales. Detailed somatic data including comorbidity and accepted risk factors were taken from the patients’ records. Results: Almost two thirds of all patients with abnormal HADS scores (65.2%) were not identified by their attending physicians as suffering from psychiatric problems. Using multiple-regression models, HADS scores for depression, but not for anxiety, proved to be an independent predictor for the clinicians’ judgements of disease severity [exp(β) = 1.08; 95% confidence interval (CI) 1.03–1.13; p < 0.01] and functional impairment [exp(β) = 1.11; 95% CI 1.05–1.17; p < 0.01]. The estimation of prognosis, however, was only related to physical predictors and showed no association with depressive symptoms or other psychosocial factors. Conclusions: Our data demonstrate that internists’ ratings of severity of illness and functional impairment, but not prognosis, are associated with HADS depression scores, whereas there is no such association with self-rated anxiety.

The relationship between anxiety disorders and physical disorders in the U.S. National Comorbidity Survey

“…Finally, we found that among individuals with one or more past-year physical disorders, co-occurrence of anxiety disorders was associated with a higher likelihood of disability and past 30-day role impairment after adjusting for the effects of comorbid mental disorders and severity of pain. These findings are inconsistent with previous smaller studies that did not find an association between anxiety and severity of physical illness [Meyer et al, 2000]. Further replication of the current-study's findings is required.…”

Anxiety as a Predictor of Improvements in Somatic Symptoms and Health Anxiety Associated with Cognitive-Behavioral Intervention in Hypochondriasis

“…This finding is consistent with those of our previous study [14] but inconsistent with those of other studies emphasizing the importance of depression in the reporting of somatic symptoms [35,36,37]. These inconsistent results may be attributable to the possibility that relatively more anxious patients with somatic symptoms than depressed patients with somatic symptoms might have been inclined to participate in the CBT intervention used in the present study.…”

Psychiatric Symptoms Associated with Scleroderma

“…The majority may manifest mild symptoms of anxiety due to apprehension and vigilance related to the perceived threat from the illness and the uncertainties regarding its etiology, prognosis and outcome. Others may develop depression generally of moderate severity [24]. However, some patients may exhibit serious psychiatric symptoms necessitating psychiatric intervention.…”
