Usability, Acceptability, and Adherence to an Electronic Self-Monitoring System in Patients With Major Depression Discharged From Inpatient Wards.

BACKGROUND: Patients suffering from depression have a high risk of relapse and readmission in the weeks following discharge from inpatient wards. Electronic self-monitoring systems that offer patient-communication features are now available to offer daily support to patients, but the usability, acceptability, and adherence to these systems has only been sparsely investigated. OBJECTIVE: We aim to test the usability, acceptability, adherence, and clinical outcome of a newly developed computer-based electronic self-assessment system (the Daybuilder system) in patients suffering from depression, in the period from discharge until commencing outpatient treatment in the Intensive Outpatient Unit for Affective Disorders. METHODS: Patients suffering from unipolar major depression that were referred from inpatient wards to an intensive outpatient unit were included in this study before their discharge, and were followed for four weeks. User satisfaction was assessed using semiqualitative questionnaires and the System Usability Scale (SUS). Patients were interviewed at baseline and at endpoint with the Hamilton depression rating scale (HAM-D17), the Major Depression Inventory (MDI), and the 5-item World Health Organization Well-Being Index (WHO-5). In this four-week period patients used the Daybuilder system to self-monitor mood, sleep, activity, and medication adherence on a daily basis. The system displayed a graphical representation of the data that was simultaneously displayed to patients and clinicians. Patients were phoned weekly to discuss their data entries. The primary outcomes were usability, acceptability, and adherence to the system. The secondary outcomes were changes in: the electronically self-assessed mood, sleep, and activity scores; and scores from the HAM-D17, MDI, and WHO-5 scales. RESULTS: In total, 76% of enrolled patients (34/45) completed the four-week study. Five patients were readmitted due to relapse. The 34 patients that completed the study entered data for mood on 93.8% of the days (872/930), sleep on 89.8% of the days (835/930), activity on 85.6% of the days (796/930), and medication on 88.0 % of the days (818/930). SUS scores were 86.2 (standard deviation [SD] 9.7) and 79% of the patients (27/34) found that the system lived up to their expectations. A significant improvement in depression severity was found on the HAM-D17 from 18.0 (SD 6.5) to 13.3 (SD 7.3; P<.01), on the MDI from 27.1 (SD 13.1) to 22.1 (SD 12.7; P=.006), and in quality of life on the WHO-5 from 31.3 (SD 22.9) to 43.4 (SD 22.1; P<.001) scales, but not on self-assessed mood (P=.08). Mood and sleep parameters were highly variable from day-to-day. Sleep-offset was significantly delayed from baseline, averaging 48 minutes (standard error 12 minutes; P<.001). Furthermore, when estimating delay of sleep-onset (with sleep quality included in the model) during the study period, this showed a significant negative effect on mood (P=.03). CONCLUSIONS: The Daybuilder systems performed well technically, and patients were satisfied with the system and had high adherence to self-assessments. The dropout rate and the gradual delay in sleep emphasize the need for continued clinical support for these patients, especially when considering sleep guidance.

Electronic monitoring of psychomotor activity as a supplementary objective measure of depression severity.

BACKGROUND: Rating scales used to assess the severity of depression e.g. the Hamilton Depression Rating Scale 17-item (HDRS-17) partly rely on the patient's subjective experience and reporting. Such subjective measures tend to have low reliability and adding objective measures to complement the assessment of depression severity would be a major step forward. AIMS: To investigate correlations between electronic monitoring of psychomotor activity and severity of depression according to HDRS-17. METHODS: A total of 36 patients with unipolar disorder (n = 18) or bipolar disorder (n = 18) and 31 healthy control persons aged 18-60 years were included. Psychomotor activity was measured using a combined heart rate and movement sensor device (Actiheart) for 3 consecutive days, 24 h a day. RESULTS: We found that sleeping heart rate (beats/min) correlated with HDRS-17 in both patients with unipolar disorder and bipolar disorder (unadjusted model: B = 0.46, 95% CI 0.037-0.89, P = 0.034). In contrast, correlations between activity energy expenditure (kJ/kg/day), cardio-respiratory fitness (mlO2/min/kg) and HDRS-17 were non-significant. CONCLUSIONS: These results suggest that measuring sleeping heart rate in non-experimental daily life could be an objective supplementary method to measure the severity of depression and perhaps indicate presence of insomnia.

Maternal depression, antidepressant use in pregnancy and Apgar scores in infants.

BACKGROUND: Use of antidepressants during pregnancy has been associated with a low Apgar score in infants but a contribution from the underlying depressive disorder might influence this association. AIMS: To estimate the effects of maternal depression and use of antidepressants during pregnancy on low Apgar scores (<7) 5 min after birth. METHOD: Register study on all pregnant women in Denmark from 1996 to 2006 linking nationwide individualised data from the Medical Birth Register, the Psychiatric Central Register and the National Prescription database. RESULTS: Infants exposed to antidepressants during pregnancy had an increased rate of a low Apgar score (odds ratio (OR) = 1.72, 95% CI 1.34-2.20). The increased rate was only found among infants exposed to selective serotonin reuptake inhibitors (SSRIs) (OR = 1.96, 95% CI 1.52-2.54), not among those exposed to newer (OR = 0.83, 95% CI 0.40-1.74) or older antidepressants (OR = 0.53, 95% CI 0.19-1.45). Maternal depression before or during pregnancy, without prescription of antidepressants, was not associated with a low Apgar score (OR = 0.44, 95% CI 0.11-1.74). Women who had only used antidepressants prior to pregnancy had no increased rate of a low Apgar score in their subsequent pregnancy, regardless of depression status. CONCLUSIONS: Use of SSRIs during pregnancy increases the risk of a low Apgar score independently of maternal depression.

Differences in the ICD-10 diagnostic subtype of depression in bipolar disorder compared to recurrent depressive disorder.

BACKGROUND: The aim of the study was to investigate whether patients with bipolar depression and patients with recurrent depressive disorder present with different subtypes of depressive episode as according to ICD-10. SAMPLING AND METHODS: All patients who got a diagnosis of bipolar affective disorder, current episode of depression, or a diagnosis of recurrent depressive disorder, current episode of depression, in a period from 1994 to 2002 at the first outpatient treatment or at the first discharge from psychiatric hospitalization in Denmark were identified in a nationwide register. RESULTS: Totally, 389 patients got a diagnosis of bipolar disorder, current episode of depression, and 5.391 patients got a diagnosis of recurrent depressive disorder, current episode of depression, at first contact. Compared with patients with a diagnosis of recurrent depressive disorder, patients with bipolar disorder, current episode of depression, were significantly less often outpatients (49.4 vs. 68.0%), significantly more often got a diagnosis of severe depression (42.7 vs. 23.3%) or a diagnosis of depression with psychotic symptoms (14.9 vs. 7.2%). The rate of subsequent hospitalization was increased for patients with bipolar disorder, current episode of depression, compared with patients with a current depression as part of a recurrent depressive disorder (HR = 1.50, 95% CI = 1.20-1.86). CONCLUSIONS: The results consistently indicate that a depressive episode is severer and/or more often associated with psychotic symptoms when it occurs as part of a bipolar disorder than as part of a recurrent depressive disorder.

[Electroconvulsive therapy].

Within psychiatry, no treatment is as effective - or controversial - as electroconvulsive therapy (ECT), and ECT is the only non-pharmacological treatment in widespread clinical psychiatry. The history of ECT as a psychiatric treatment is outlined in this review, and the efficacy in four diagnostic entities is reviewed along with side effects. The evidence shows compelling effect of ECT when administered within affective disorders, delirium and psychotic states.

Persistent genital arousal disorder: confluent patient history of agitated depression, paroxetine cessation, and a tarlov cyst.

We report a case of a woman suffering from persistent genital arousal disorder (PGAD) after paroxetine cessation. She was admitted to a psychiatric department and diagnosed with agitated depression. Physical investigation showed no gynaecological or neurological explanation; however, a pelvic MRI scan revealed a Tarlov cyst. Size and placement of the cyst could not explain the patient's symptoms; thus neurosurgical approach would not be helpful. Her depression was treated with antidepressant with little effect. Electroconvulsive therapy improved the patient's symptoms though they did not fully resolve. More awareness of PGAD and thorough interdisciplinary conferences are necessary to insure an unequivocal treatment strategy.

The effects of maternal depression and use of antidepressants during pregnancy on risk of a child small for gestational age.

RATIONALE: Use of antidepressants during pregnancy has been associated with an increased rate of children small for gestational age (SGA), but it is unclear whether this is due to an effect of the underlying depressive disorder. OBJECTIVES: This study aimed to investigate the effect of antidepressants on SGA in a nationwide sample and to separate the effect of exposure to antidepressants in utero from the effect of maternal depression. METHODS: A register study was conducted on all pregnant women in Denmark from 1996 to 2006 linking nationwide individualized data from the Medical Birth Register, the Psychiatric Central Register, and a prescription database. The rate of SGA (birth weight below the 10 percentile at given gestational week) was investigated for children exposed in utero to antidepressants or to a maternal psychiatric diagnosis of depression compared to children not prenatally exposed to antidepressants or maternal diagnosis. RESULTS: A total of 673,853 pregnancies were included in the study of which 35.737 women had a diagnosis of depression and/or used antidepressants before end of pregnancy. Antidepressant use during pregnancy was weakly associated with SGA (hazard ratios (HR) = 1.19; 95 % confidence interval (CI), 1.11-1.28), whereas a psychiatric diagnosis before or during pregnancy was not (HR = 1.02; 95 % CI, 0.92-1.13). The association for use during pregnancy was found for selective serotonin reuptake inhibitors and newer antidepressants, but not for older antidepressants. CONCLUSIONS: The use of antidepressants during pregnancy slightly increases the rate of SGA. The association seems unrelated to the underlying maternal depressive disorder.

Differences in psychomotor activity in patients suffering from unipolar and bipolar affective disorder in the remitted or mild/moderate depressive state.

BACKGROUND: Abnormalities in psychomotor activity are a central and essential feature of affective disorder. Studies measuring differences in psychomotor activity between unipolar and bipolar disorder show divergent results and none have used a combined heart rate and movement monitor for measuring activity during free-living conditions. OBJECTIVE: To compare objectively measured psychomotor activity in patients with unipolar and bipolar disorder in a remitted or mild/moderate depressive state. Further, both groups were compared to a healthy control group. METHODS: A cross-sectional study of outpatients suffering from unipolar (n=20) and bipolar (n=18) disorder and healthy controls (n=31), aged 18-60 years. For three consecutive days a combined acceleration (m/s(2)) and heart rate (beats per minute) monitoring was used in conjunction with a step test to estimate activity energy expenditure (J/min/kg) as measures of psychomotor activity and physical fitness. RESULTS: Overall score on Hamilton-17 items ranged between 0 and 22. Patients had higher sleeping heart rate (p<0.001), lower fitness (p=0.02), lower acceleration (p=0.004), and lower activity energy expenditure (p=0.004) compared to controls. Comparing unipolar and bipolar patients and adjusting for differences in Hamilton-17 revealed lower acceleration (p=0.01) and activity energy expenditure in bipolar patients (p=0.02); the difference was most prominent in the morning. CONCLUSIONS: Electronic monitoring of psychomotor activity may be a promising additional tool in the distinction between unipolar and bipolar affective disorder when patients present in a remitted or depressive state.

[Extralegal coercive measures in psychiatric wards-- patients' perspectives]. / Ekstralegale tvangsforanstaltninger i psykiatrien--et patientperspektiv.

INTRODUCTION: A revision of the Danish Mental Health Act is planned to take place in 2005-2006. The Ministry of Health requires investigation into whether extralegal coercive measures take place in psychiatric wards. Extralegal coercion refers to restrictions and rules not included in the current Mental Health Act and considered by patients to be coercion. MATERIALS AND METHODS: Twenty-two psychiatric patients participated in four group interviews directed by two physicians at four University Hospitals in Copenhagen, Denmark. The patients were asked to define what they perceived as extralegal coercion, house rules and psychiatric treatment. RESULTS: The majority of patients perceived lack of single rooms, restrictions on leaving the ward and shielding, i.e., being confined to one's room, to be extralegal coercion. A few also found the pressure to take medication and collection of clothes items to be extralegal coercion. Rules on smoking, clothing, day and night routines, the use of radio and TV, drugs, alcohol, visits, eating and the use of telephones were considered not extralegal coercion but necessary house rules. House rules should be clear and stated in writing. Restrictions on the use of money and locking of the front door at night were accepted in certain situations, hence not considered to be extralegal coercion. DISCUSSION: Extralegal coercion does occur in psychiatric wards but in certain situations is accepted if documented. House rules are considered to be necessary and not extralegal coercion. Increased use of compulsory protocols for documenting coercive measures was not considered to be necessary, but documentation in patients' files was useful alternative.

Auto-vampirism in schizophrenia.

Vampirism and auto-vampirism have been reported for centuries as very rare features. A relationship between vampirism auto-vampirism and mental disorders has been established, especially with regard to schizophrenia. This case study reports auto-vampirism in a 35-year-old schizophrenic woman. The Present State Examination was used to obtain a valid diagnosis. Auto-vampirism proved to be part of a bizarre delusion of a purification process. This patient reported experiences of depersonalization and auditory commanding hallucinations that made her strive for auto-vampirism. Although rare, auto-vampirism can be detected as a symptom in schizophrenia and can be treated.

Repetitive transcranial magnetic stimulation as add-on antidepressant treatment. The applicability of the method in a clinical setting.

Recent research indicates that repetitive transcranial magnetic stimulation (rTMS) over the frontal cortex has an antidepressant effect. The aim of the present pilot study was to assess the antidepressant effect, side-effects and the applicability in daily clinical practice of left prefrontal high-frequency rTMS. Fifteen inpatients with major depression (ICD-10 and DSM-IV) were randomized to receive 15 days of real left prefrontal high-frequency rTMS (20 trains of 10 s, 60-s interval, 10 Hz, 90% of motor threshold) or sham rTMS as add on to conventional antidepressant treatment. Depressive symptoms and side-effects were evaluated blindly during the treatment period. Five out of eight patients receiving real rTMS suffered from local discomfort during treatment. Three of them dropped out and the project was closed for that reason. Real rTMS did not add efficacy to standard antidepressant medication. This pilot study did not confirm the antidepressant effect of left frontal high-frequency rTMS. Unwanted effects led to considerable patient drop-out and premature termination of the study. The result suggests that alternative treatment delivery technology should be considered.
