Assessment of decisional capacity: Prevalence of medical illness and psychiatric comorbidities.

Studies on decisional capacity have primarily focused on cognitive disorders, whereas noncognitive disorders remain understudied. The purpose of our study was to assess decisional capacity across a wide spectrum of medical and psychiatric disorders. More than 2,500 consecutive consults were screened for decisional capacity, and 336 consults were reviewed at Bellevue Hospital Center in New York. Sociodemographic and medical variables, medical and psychiatric diagnoses, as well as decisional capacity assessments were recorded and analyzed. Consults for decisional capacity were most commonly called for in male patients with cognitive and substance abuse disorders. Less commonly, consults were called for patients with mood or psychotic disorders. Overall, about two thirds of patients (64.7%) were deemed not to have decisional capacity. Among medical diagnoses, neurological disorders contributed to decisional incapacity, and among the psychiatric diagnoses, cognitive disorders were most frequently documented in cases lacking decisional capacity (54.1%) and interfered more commonly with decisional capacity than substance abuse or psychotic disorders (37.2 and 25%). In contrast, patients with mood disorders usually retained their decisional capacity (32%). Generally, the primary treatment team's assessment was accurate and was confirmed by the psychiatric service. Although decisional capacity assessments were most commonly requested for patients with substance abuse and cognitive disorders, the latter generally affected the ability to make healthcare decisions the most. Further, cognitive disorders were much more likely to impair the ability to make appropriate healthcare decisions than substance abuse or psychotic disorders.

Medical Comorbidity in a Bipolar Outpatient Clinical Population

The presence of medical illnesses among inpatients with bipolar disorder is known to complicate treatment and lengthen hospital stay. However, except for a few specific diseases, little is known about prevalence of medical illnesses in bipolar outpatients and the effect it may have on treatment. The authors sought to assess the presence of medical illnesses in a large outpatient clinical sample of bipolar patients, and the effect that medical illnesses may have on the clinical assessment and treatment of the underlying bipolar disorder. Using the Duke University Medical Center clinical database, the authors categorized the medical diagnoses of 1379 patients who were treated with bipolar disorder from 2001 to 2002 through outpatient psychiatric clinics. The prevalence of medical comorbidities was examined, as well as the effect their presence had on the clinician's assessment of disease severity and time to improvement. As expected, medical comorbidities increased with age. The most common systemic illnesses in bipolar outpatients were Endocrine and Metabolic Diseases (13.6% of the sample), Diseases of the Circulatory System (13.0%), and Diseases of the Nervous System and Sense Organs (10.7%). Significant specific diseases included cardiovascular diseases/hypertension (10.7%), COPD/asthma (6.1%), diabetes (4.3%), HIV infection (2.8%), and hepatitis C infection (1.9%). Clinicians assessed greater severity of illness in patients with increasing numbers of comorbid conditions; however, the time to recovery was not significantly effected by the presence of medical comorbidity. In conclusion, comorbid medical illnesses are common in bipolar outpatients, increasing with age. HIV rates may be increased relative to population norms. Their presence compounds the severity of the illness at time of presentation.

CAPACITY FOR SELF-CARE OF PERSONS WITH MENTAL ILLNESSES LIVING IN COMMUNITY RESIDENCES AND THE ABILITY OF THEIR SURROGATE FAMILIES TO PERFORM HEALTH CARE FUNCTIONS

Persons with chronic mental illnesses have a higher prevalence of medical illnesses and higher mortality rates than the general population. Those living in the community are usually linked with mental health services but are expected to manage their own medical care. The ability to manage their health care and the ability of "surrogate families" to assist them were measured among residents and staff of supervised community residences. In its surrogate role, the agency promoted routine health examinations and followup care. Its staff was a central resource for the residents, who sought out staff members for assistance with their health problems. However, residents and staff alike lack knowledge about health problems, medications, and approaches to modifying unhealthy lifestyle practices. Although residents identified lack of knowledge about sexually transmitted diseases as a major concern, staff indicated discomfort with this topic. These findings suggest the importance of supporting chronically mentally ill persons and residential staff in managing residents' health care functions.

Prevalence of medical illness in patients with anxiety disorders.

This investigation examines the prevalence and characteristics of medical illness in 711 patients enrolled in the Harvard/Brown Anxiety Disorders Research Program (HARP), a multi-center, longitudinal study of anxiety disorders. Eligible subjects were those with present or past index anxiety disorders: panic disorder without agoraphobia, panic disorder with agoraphobia, agoraphobia without panic disorder, social phobia, or generalized anxiety disorder. They were assessed by trained raters using structured diagnostic interviews and the Medical History Form II. Patients with panic disorder and co-morbid major depressive disorder had significantly higher rates of reported medical illness than anxiety disorder patients without depression. When the rates of medical illness for all subjects were compared with those from the Rand Health Insurance Experiment, we found the prevalence of several medical problems to be disproportionately increased. Although our results are preliminary, it appears that patients with panic disorder have more reported medical problems than the public at large, in particular, more ulcer disease, angina, and thyroid disease. Somatic complaints in patients with panic disorder, therefore, need to be carefully considered.

Health attitudes of psychiatric inpatients.

Despite the high prevalence of medical illness in the mentally ill population, little is known about the health attitudes of patients with combined medical and psychiatric disorders. We compared the health attitudes of a group of inpatients with concomitant medical and psychiatric illness, a group of physically healthy psychiatric inpatients, and a group of normals. The instrument used was the Illness Attitude Scales, a self-rating scale designed to explore beliefs which can be responsible for hypochondriacal attitudes. A self-rating scale of psychological distress, the Symptom Questionnaire, was administered as well. Compared to normals, psychiatric patients displayed more hypochondriasis. There were no significant differences in psychological distress or health attitudes between patients with concomitant physical and psychiatric disorder and physically healthy psychiatric patients.

Rational preoperative evaluation.

Clinical data from two hundred consecutive patients undergoing surgical procedures at the Salt Lake City VA Hospital form the basis of this study. Results of nine commonly ordered preoperative tests (blood count, differential, electrolytes, chemistry panel, urinalysis, prothrombin time, partial thromboplastin time, electrocardiogram, and chest X-ray) were matched with the preoperative history and physical examination and the outcome of surgery in each patient. Each test was examined by the frequency with which it was ordered, the frequency with which it was abnormal, and the frequency with which the abnormal result affected preoperative care. A prevalence of medical illness was found in this population, with 47.5% having a major cardiovascular diagnosis, 35.5% a metabolic or endocrine disease, and 28% a major pulmonary diagnosis. A total of 1271 tests were performed, with 477 (35.5%) showing some abnormality. However, only 76 (5.9%) changed the patient's management before surgery. All but five of these abnormalities were predictable from the clinical evaluation and these five were minor. The overall postoperative complication rate was 9%. No complication was attributed to the omission of a preoperative test. No surgical cases were cancelled during the study period based solely on a preoperative test. We conclude that many preoperative tests can be safely eliminated by ordering only those based on a specific abnormality in the history or physical examination, resulting in more cost-effective surgical care.
