Clinical Assessment of Judgment in Adults and the Elderly: Development and Validation of the Three Domains of Judgment Test-Clinical Version (3DJT-CV).

(1) Background: This article discusses the first two phases of development and validation of the Three Domains of Judgment Test (3DJT). This computer-based tool, co-constructed with users and capable of being administered remotely, aims to assess the three main domains of judgment (practical, moral, and social) and learn from the psychometric weaknesses of tests currently used in clinical practice. (2) Method: First, we presented the 3DJT to experts in cognition, who evaluated the tool as a whole as well as the content validity, relevance, and acceptability of 72 scenarios. Second, an improved version was administered to 70 subjects without cognitive impairment to select scenarios with the best psychometric properties in order to build a future clinically short version of the test. (3) Results: Fifty-six scenarios were retained following expert evaluation. Results support the idea that the improved version has good internal consistency, and the concurrent validity primer shows that 3DJT is a good measure of judgment. Furthermore, the improved version was found to have a significant number of scenarios with good psychometric properties to prepare a clinical version of the test. (4) Conclusion: The 3DJT is an interesting alternative tool for assessing judgment. However, more studies are needed for its implementation in a clinical context.

Factors affecting recruitment into psychiatry: a canadian experience.

OBJECTIVE: There is a projected shortage of psychiatrists in Canada in forthcoming years. This study assessed factors in medical school education that are associated with students selecting psychiatry first and matching as a discipline. METHOD: The Canadian Organization of Undergraduate Psychiatry Educators (COUPE) conducted telephone interviews and sent e-mail questionnaires to the 17 medical schools across Canada; all schools provided data for 2012. Relevant data were obtained from the Canadian Resident Matching Service. Statistics were performed using v12 STATA program, and significance was set at a p value of <0.05. RESULTS: Medical student enrollment ranged from 54 to 266 students (mean = 158 ± 16). Of these students, 4.9 ± 0.6 % ranked psychiatry as their first choice for residency. Final match results yielded similar numbers at 5.0 ± 0.6 %. Ten out of 17 programs filled all psychiatry residency positions, whereas the remaining 7 programs had vacancy rates from 5 to 100 % (mean = 43.4 ± 15.1 %). Medical students were exposed to an average of 2.8 ± 0.5 pre-clerkship psychiatry weeks and 6.2 ± 0.3 clerkship weeks. Linear regression analysis demonstrated that the percentage of graduating medical students entering a psychiatry residency program could be predicted from the number of weeks of pre-clerkship exposure (p = 0.01; R(2) = 0.36) but not from the number of clerkship weeks (p = 0.74). CONCLUSIONS: This study indicates that the duration of pre-clerkship exposure to psychiatry predicts the number of students selecting psychiatry as their first choice as a discipline. Thus, increasing the duration of pre-clerkship exposure may increase the enrollment of medical students into psychiatry.

Late-onset-psychosis: cognition.

BACKGROUND: The objectives of the study were to characterize and compare the cognitive profile and natural evolution of patients presenting late-onset psychotic symptoms (LOPS: onset ≥ 50 years old) to those of elderly patients (≥ 50 years old) with life-long/early-onset schizophrenia (EOS: onset <40 years old). METHODS: Neuropsychological profiles of 15 LOPS patients were compared to those of 17 elderly EOS patients and to those of two control groups (n = 11/group). The evolution of the two patient groups was compared using an independent diagnostic consensual procedure involving a geriatric psychiatry physician/clinician and a neuropsychologist blinded to the initial psychiatric diagnosis. RESULTS: EOS presented significant memory and executive impairments when compared to controls but there was no significant difference between LOPS and their controls when age and education were taken into account. However, a detailed inspection of normative data suggests more executive impairments in LOPS than in EOS. The clinical judgment of experts was in favour of significant cognitive deficits with or without dementia in most LOPS (82.3%-94.1%) and EOS (80.0%-93.3%) patients. Regarding evolution, mild cognitive impairment (MCI) and vascular cognitive impairment (VCI) were the most common clinical diagnoses made by geriatric psychiatry physicians/clinicians for the LOPS (40%). In addition, 20% of LOPS versus 5.9% of EOS patients met the diagnostic criteria for dementia by consensus of the experts. Cerebral abnormalities were confirmed (CT scan; SPECT) in 73.3% of LOPS patients. CONCLUSION: The present results suggest cognitive deficits (mostly of executive functions) and vascular and neurodegenerative vulnerability in LOPS. Further studies with larger samples are needed to confirm the present findings.

Affective correlates of fear of falling in elderly persons.

OBJECTIVE: Fear of falling is common in older people, occurring on average in 50% of those who have fallen in the previous year. Little is known about the psychological correlates of fear of falling. The purpose of this study was to determine whether clinically significant depression and anxiety were independently associated with fear of falling. METHODS: This was a cross-sectional study of 105 persons age > or =60 years, admitted to medical or orthopedic wards, who had fallen at least once in the previous 12 months. Fear of falling was assessed using two different constructs: 1) intensity of fear; and 2) self-efficacy. Depressive and anxiety disorders were assessed with the Structured Clinical Interview for DSM-IV. Depression and anxiety severity were assessed with the Hospital Anxiety and Depression Scale. Demographic, physical, functional, and social variables previously found to be associated with fear of falling were also measured. Logistic-regression and multiple-regression analyses were used to examine the independent association of affective variables with fear of falling. RESULTS: Depressive disorders, anxiety disorders, depression severity, and anxiety severity had significant independent associations with both constructs of fear of falling. Of all the variables that were measured, depressive disorders and depression severity had the strongest associations with fear of falling. CONCLUSION: Affective variables had a stronger association with fear of falling than non-affective variables in a hospital-based group of subjects. Further research is needed to determine whether similar findings occur in a community-based sample of older people.

Diagnosis and management of panic disorder in older patients.

Panic disorder occurs less frequently in the elderly than in younger adults and rarely starts for the first time in old age. Panic attacks that begin in late life should prompt the clinician to conduct a careful search for a depressive disorder, physical illness or drugs that could be contributing to their presence. When panic attacks do occur in the elderly, the symptoms are qualitatively similar to those experienced by younger people. The elderly, however, may have fewer and less severe symptoms and exhibit less avoidant behaviour. As panic disorder is typically a chronic or recurrent condition, its management requires a long-term approach. With the exception of one descriptive pilot study, there have been no randomised controlled trials of the treatment of panic disorder in later life. Therefore, recommendations regarding the management of this disorder in the elderly must be extrapolated from research pertaining to younger patients. Selective serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants, monoamine oxidase inhibitors, benzodiazepines and cognitive behavioural therapy are efficacious treatments for panic disorder. There are no consistent differences in efficacy between classes of medications or between pharmacotherapy and cognitive behavioural therapy. Furthermore, there are no reliable predictors of response to one type of treatment compared with another. Treatment selection, therefore, depends on an individual assessment of the risks and benefits of each type of treatment (taking into account comorbid psychiatric and physical conditions), patient preference, cost and the availability of therapists skilled in cognitive behavioural techniques. As a general rule, antidepressant medication is preferable to a benzodiazepine as a first-line treatment for panic disorder in the elderly, especially given the high level of comorbidity between panic disorder and depressive disorders. Of the antidepressants, an SSRI is recommended as the initial choice of treatment in older patients. Anxious patients frequently misattribute somatic symptoms of anxiety to adverse effects of medication. Adherence with treatment, therefore, can be enhanced by starting antidepressant medication at a low dosage so as to avoid initial exacerbation of anxiety (but then gradually increasing the dosage to the therapeutic range), frequent follow-up during the first few weeks of treatment, discussion about potential adverse effects and addressing any other concerns the patient may have about taking medication. Given the delayed onset of action of antidepressant medication, the short-term use of adjunctive lorazepam in the first few weeks of treatment may be helpful in selected patients.

Intravenous phosphate in the intensive care unit: more aggressive repletion regimens for moderate and severe hypophosphatemia.

OBJECTIVE: To evaluate efficacy and safety of aggressive correction of hypophosphatemia with intravenous potassium phosphate in the ICU. DESIGN AND SETTING: Randomized interventional prospective study in the medical and surgical ICU of a tertiary university hospital. PATIENTS: Critically ill patients with hypophosphatemia between June and November 1998. MEASUREMENTS AND RESULTS: Patients with moderate hypophosphatemia (<0.65 and >0.40 mmol/l; n=37) were randomized into two groups: group 1 received 30 mmol potassium phosphate intravenously in 50 ml saline over 2 h, and group 2 received 30 mmol potassium phosphate in 100 ml saline over 4 h. Patients with severe hypophosphatemia (<0.40 mmol/l; n=10) were also randomized into two groups: group 3 received 45 mmol potassium phosphate intravenously in 100 ml saline over 3 h, and group 4 received 45 mmol potassium phosphate in 100 ml saline over 6 h. Electrolytes, blood gas, renal function were monitored until day 3; urine was collected during and until 6 h after infusions. The overall efficacy of the protocols was 98% by the end of the infusion. There was no statistical difference in phosphate values between groups at the end of infusion or at 24 h. No adverse events were noted; one patient had an increase in serum potassium to 6.1 mmol/l. Phosphaturia in all groups was elevated as evidenced by fractional excretion above 20%. CONCLUSIONS: More rapid administration of large potassium phosphate boluses is effective and safe for correcting hypophosphatemia in ICU patients with preserved renal function if baseline serum potassium is below 4 mmol/l.

Effective use of electroconvulsive therapy in late-life depression.

OBJECTIVE: To review literature pertaining to the efficacy, safety, and tolerability of electroconvulsive therapy (ECT) in treating late-life depression. METHOD: We undertook a literature review with an emphasis on research studies published in the last 10 years. RESULTS: There is a positive association between advancing age and ECT efficacy. Age per se does not necessarily increase the risk of cognitive side effects from ECT, but this risk is increased by age-associated neurological conditions such as Alzheimer's dementia and cerebrovascular disease. With appropriate evaluation and monitoring, ECT can be used safely in patients of very advanced age and in those with serious medical conditions. Several technical factors, including dose of electricity relative to a patient's seizure threshold, position of electrodes, frequency of administration, and total number of treatments, have an impact on the efficacy and cognitive side effects of ECT and need to be taken into account when administering ECT. Naturalistic studies have found that 50% of more of patients have a relapse of depression within 6 to 12 months of discontinuing acute ECT. CONCLUSIONS: In recent years, there has been substantial progress in our understanding of the effect of technical factors on the efficacy and cognitive side effects of ECT. When administered in an optimal manner, ECT is a safe, well-tolerated, and effective treatment in older patients. Relapse of depression after response to ECT remains a significant problem, and there is a need for further research into the prediction and prevention of post-ECT relapse.
