Preventie van depressie en angst in verzorgingstehuizen
Achtergrond
Bewoners van verzorgingshuizen vormen een risicogroep voor het ontwikkelen van een depressieve en/of angststoornis. Deze stoornissen komen veel voor en hebben een grote impact op het welzijn en functioneren van de betrokkene, maar worden vaak slecht herkend. Wij vroegen ons af of een stepped-care programma ter preventie van depressieve en angststoornissen in verzorgingshuizen haalbaar en effectief zou kunnen zijn.
Methoden
In een pragmatische gerandomiseerde gecontroleerde trial vergeleken we de effecten van het programma met gebruikelijke zorg in veertien verzorgingshuizen. In totaal deden 185 bewoners mee, die op de Centre for Epidemiologic Studies Depression Scale (CES-D) minstens 8 punten scoorden, niet leden aan een depressieve of angststoornis en ook niet aan een ernstige cognitieve stoornis. De deelnemers kregen een stepped-care preventieprogramma (n = 93) of gebruikelijke behandeling (n = 92). De deelnemers aan het preventieprogramma kregen eerst een afwachtend beleid en als ze niet opknapten achtereenvolgens een zelfhulpinterventie, een psychologische life-review en een verwijzing naar de huisarts. Onze primaire uitkomstmaat was de incidentie van een depressieve stoornis of angststoornis gedurende het jaar na inclusie.
Resultaten
De incidentie van depressie en angst samen nam niet af door de interventie: de gecombineerde incidence rate ratio (IRR) was 0,50 (95%-betrouwbaarheidsinterval (BI) 0,23 tot 1,12). Ten opzichte van de gebruikelijke zorg bracht het preventieprogramma wel het indicentierisico voor depressie omlaag (IRR 0,26; 95%-BI 0,12 tot 0,80) maar niet dat voor angst (IRR 1,32; 95%-BI 0,48 tot 3,62).
Conclusie
De resultaten suggereren dat het toegepaste steppedcare preventieprogramma bij ouderen in verzorgingshuizen wel helpt tegen depressie, maar niet tegen angst
Depression and anxiety, an Indicated Prevention (DIP) protocol in homes for the elderly: feasibility and (cost) effectiveness of a stepped care programme
BACKGROUND: Depressive and anxiety disorders are a very common, serious and underdetected problem in homes for the elderly. Elderly persons in residential homes are at high risk for developing major depressive and anxiety disorders, and, therefore, deserve attention with regard to prevention. METHODS/DESIGN: This protocol describes a randomised trial on the feasibility and (cost) effectiveness of a stepped-care programme for prevention of depressive and anxiety disorders in homes for the elderly. The main outcome measure is the incidence of depressive and anxiety disorder in one year with a two years follow up. Secondary outcomes are symptoms of depression and anxiety, quality of life, direct health care costs and satisfaction with treatment. DISCUSSION: The number of studies examining the effects of preventive interventions on the incidence of mental disorders in the elderly population is very small. However, indicated prevention by means of a stepped-care programme seems to be an important option for decreasing the burden of illness for residents and their caregivers. This study contributes to the body of knowledge in this field. Positive effects may contribute to further use and development of tailored, (cost-) effective and easy to use interventions in a preventive stepped-care programme.

Effectiveness of a stepped-care intervention to prevent major depression in patients with type 2 diabetes mellitus and/or coronary heart disease and subthreshold depression: A pragmatic cluster randomized controlled trial
Purpose
Given the public health significance of poorly treatable co-morbid major depressive disorders (MDD) among patients with type 2 diabetes mellitus (DM2) and coronary heart disease (CHD), we need to investigate whether strategies to prevent the development of major depression could reduce its burden of disease. We therefore evaluated the effectiveness of a stepped-care program for subthreshold depression in comparison with usual care in patients with DM2 and/or CHD.
Methods
A cluster randomized controlled trial, with 27 primary care centers serving as clusters. A total of 236 DM2 and/or CHD patients with subthreshold depression (nine item Patient Health Questionnaire (PHQ-9) score ≥ 6, no current MDD according to DSM-IV criteria) were allocated to the intervention group (N = 96) or usual care group (n = 140). The stepped-care program was delivered by trained practice nurses during one year and consisted of four sequential treatment steps: watchful waiting, guided self-help, problem solving treatment and referral to the general practitioner. The primary outcome was the 12-month cumulative incidence of MDD as measured with the Mini International Neuropsychiatric Interview (MINI). Secondary outcomes included severity of depression (measured by PHQ-9) at 3, 6, 9 and 12 months.
Results
Of 236 patients (mean age, 67,5 (SD 10) years; 54.7% men), 210 (89%) completed the MINI at 12 months. The cumulative incidence of MDD was 9 of 89 (10.1%) participants in the intervention group and 12 of 121 (9.9%) participants in the usual care group. We found no statistically significant overall effect of the intervention (OR = 1.21; 95% confidence interval (0.12 to 12.41)) and there were no statistically significant differences in the course or severity of depressive symptoms between the two groups.
Conclusions
This study suggest that Step-Dep was not more effective in preventing MDD than usual care in a primary care population with DM2 and/or CHD and subthreshold depression
Plasma biomarkers of depressive symptoms in older adults
The pathophysiology of negative affect states in older adults is complex, and a
host of central nervous system and peripheral systemic mechanisms may play
primary or contributing roles. We conducted an unbiased analysis of 146 plasma
analytes in a multiplex biochemical biomarker study in relation to number of
depressive symptoms endorsed by 566 participants in the Alzheimer's Disease
Neuroimaging Initiative (ADNI) at their baseline and 1-year assessments.
Analytes that were most highly associated with depressive symptoms included
hepatocyte growth factor, insulin polypeptides, pregnancy-associated plasma
protein-A and vascular endothelial growth factor. Separate regression models
assessed contributions of past history of psychiatric illness, antidepressant or
other psychotropic medicine, apolipoprotein E genotype, body mass index, serum
glucose and cerebrospinal fluid (CSF) Ï„ and amyloid levels, and none of
these values significantly attenuated the main effects of the candidate analyte
levels for depressive symptoms score. Ensemble machine learning with Random
Forests found good accuracy (∼80%) in classifying groups with and
without depressive symptoms. These data begin to identify biochemical biomarkers
of depressive symptoms in older adults that may be useful in investigations of
pathophysiological mechanisms of depression in aging and neurodegenerative
dementias and as targets of novel treatment approaches
Statistical design and analysis in trials of proportionate interventions: a systematic review
Background: In proportionate or adaptive interventions, the dose or intensity can be adjusted based on individual need at predefined decision stages during the delivery of the intervention. The development of such interventions may require an evaluation of the effectiveness of the individual stages in addition to the whole intervention. However, evaluating individual stages of an intervention has various challenges, particularly the statistical design and analysis. This review aimed to identify the use of trials of proportionate interventions and how they are being designed and analysed in current practice. Methods: We searched MEDLINE, Web of Science and PsycINFO for articles published between 2010 and 2015 inclusive. We considered trials of proportionate interventions in all fields of research. For each trial, its aims, design and analysis were extracted. The data synthesis was conducted using summary statistics and a narrative format.
Results: Our review identified 44 proportionate intervention trials, comprising 28 trial results, 13 protocols and three secondary analyses. These were mostly described as stepped care (n=37) and mainly focussed on mental health research (n=30). The other studies were aimed at finding an optimal adaptive treatment strategy (n=7) in a variety of therapeutic areas. Further terminology used included adaptive intervention, staged intervention, sequentially multiple assignment trial or a two-phase design. The median number of decision stages in the interventions was two and only one study explicitly evaluated the effect of the individual stages. Conclusions: Trials of proportionate staged interventions are being used predominantly within the mental health field. However, few studies consider the different stages of the interventions, either at the design or the analysis phase, and how they may interact with one another. There is a need for further guidance on the design, analyses and reporting across trials of proportionate interventions
Patients’ and practice nurses’ perceptions of depression in patients with type 2 diabetes and/or coronary heart disease screened for subthreshold depression
Background
Comorbid depression is common in patients with type 2 diabetes (DM2) and/or coronary heart disease (CHD) and is associated with poor quality of life and adverse health outcomes. However, little is known about patients’ and practice nurses’ (PNs) perceptions of depression. Tailoring care to these perceptions may affect depression detection and patient engagement with treatment and prevention programs. This study aimed to explore patients’ and PNs’ perceptions of depression in patients with DM2/CHD screened for subthreshold depression.
Methods
A qualitative study was conducted as part of a Dutch stepped-care prevention project. Using a purposive sampling strategy, data were collected through semi-structured interviews with 15 patients and 9 PNs. After consent, all interviews were recorded, transcribed verbatim and analyzed independently by two researchers with Atlas.ti.5.7.1 software. The patient and PN datasets were inspected for commonalities using a constant comparative method, from which a final thematic framework was generated.
Results
Main themes were: illness perception, need for care and causes of depression. Patients generally considered themselves at least mildly depressed, but perceived severity levels were not always congruent with Patient Health Questionnaire 9 scores at inclusion. Initially recognizing or naming their mental state as a (subthreshold) depression was difficult for some. Having trouble sleeping was frequently experienced as the most burdensome symptom. Most experienced a need for care; psycho-educational advice and talking therapy were preferred. Perceived symptom severity corresponded with perceived need for care, but did not necessarily match help-seeking behaviour. Main named barriers to help-seeking were experienced stigma and lack of awareness of depression and mental health care possibilities. PNs frequently perceived patients as not depressed and with minimal need for specific care except for attention. Participants pointed to a mix of causes of depression, most related to negative life events and circumstances and perceived indirect links with DM2/CHD.
Conclusion
Data of the interviewed patients and PNs suggest that they have different perceptions about (subthreshold) depressive illness and the need for care, although views on its causes seem to overlap more
