Joint effect of depression and chronic conditions on disability: results from a population-based study.
ABSTRACT To estimate and compare the prevalence of functional disability in individuals with both chronic medical conditions and comorbid major depression and individuals with either chronic medical conditions or major depression alone and to determine the joint effect of depression and chronic conditions on functional disability. Evidence exists that major depression interacts with physical illness to amplify the functional disability associated with many medical conditions.
We used data from the Canadian Community and Health Survey Cycle 2.1 (n = 46,262), a nationally representative survey conducted in 2003 by Statistics Canada. Depression, chronic conditions, and functional disability were assessed by personal/telephone interview.
Prevalence of functional disability was higher in subjects with chronic conditions and comorbid major depression (46.3%) than in individuals with either chronic conditions (20.9%) or major depression (27.8%) alone. With no chronic conditions and no major depression as reference and after adjusting for relevant covariates, the odds ratio of functional disability was 2.49 (95% confidence interval (CI), 1.91-3.26) for major depression, 2.12 (95% CI, 1.93-2.32) for chronic conditions, and 6.34 (95% CI, 5.35-7.51) for chronic conditions and comorbid major depression.
The results suggest that there is a joint effect of depression and chronic conditions on functional disability. Research and social policies should focus on the treatment of depression in chronic conditions.

ABSTRACT: This study of 2,163 adult chronic, non-cancer-pain, long-term opioid therapy patients examines the relationship of depression to functional disability by measuring average pain interference, activity limitation days, and employment status. Those with more depression symptoms compared to those with fewer were more likely to have worse disability on all 3 measures (average pain interference score >5, OR = 5.36, p < .0001; activity limitation days ≥ 30, OR = 4.05, p < .0001; unemployed due to health reasons, OR = 4.06, p < .0001). Depression might play a crucial role in the lives of these patients; identifying and treating depression symptoms in chronic pain patients should be a priority.Journal of Social Work in Disability & Rehabilitation 04/2012; 11(2):128-42.

ABSTRACT: Key messages Many people with long-term physical health conditions also have mental health problems. These can lead to significantly poorer health outcomes and reduced quality of life. Costs to the health care system are also significant – by interacting with and exacerbating physical illness, co-morbid mental health problems raise total health care costs by at least 45 per cent for each person with a long-term condition and co-morbid mental health problem. This suggests that between 12 per cent and 18 per cent of all NHS expenditure on long-term conditions is linked to poor mental health and wellbeing – between £8 billion and £13 billion in England each year. The more conservative of these figures equates to around £1 in every £8 spent on long-term conditions. People with long-term conditions and co-morbid mental health problems disproportionately live in deprived areas and have access to fewer resources of all kinds. The interaction between co-morbidities and deprivation makes a significant contribution to generating and maintaining inequalities. Care for large numbers of people with long-term conditions could be improved by better integrating mental health support with primary care and chronic disease management programmes, with closer working between mental health specialists and other professionals. Collaborative care arrangements between primary care and mental health specialists can improve outcomes with no or limited additional net costs. Innovative forms of liaison psychiatry demonstrate that providing better support for co-morbid mental health needs can reduce physical health care costs in acute hospitals. Clinical commissioning groups should prioritise integrating mental and physical health care more closely as a key part of their strategies to improve quality and productivity in health care. n Improved support for the emotional, behavioural and mental health aspects of physical illness could play an important role in helping the NHS to meet the Quality, Innovation, Productivity and Prevention (QIPP) challenge. This will require removal of policy barriers to integration, for example, through redesign of payment mechanisms.01/2012; The Kings Fund., ISBN: 978-1-85717-633-9

ABSTRACT: Physical and depressive disorders frequently co-occur, but effects of physical health on depression treatment outcomes have received little research. This study aimed to compare treatment outcomes between people with depressive disorder with and without comorbid physical disorders. A Korean nationwide sample of 723 people with depressive disorder initiated on antidepressant treatment, and re-evaluated at 1, 2, 4, 8, and 12 weeks later. Assessment scales for evaluating depressive symptoms (HAMD), anxiety (HAMA), global severity (CGI-s), and functioning (SOFAS) were administered at baseline and every follow-up visit. Achievement of remission or response was defined only when these were maintained to the 12 weeks study endpoint or to the last follow-up examination, if earlier, with the date of the first observed remission point applied as the timing of remission. Logistic regression and Cox proportional hazards models were used. Of the sample, 247 (34%) had at least one physical disorder. This was associated with lower socioeconomic status and more severe depressive symptoms at baseline, but was not associated with any treatment related characteristics including antidepressant type and regimen, concomitant medications, side effects, and duration of treatment period. After adjustment, patients with physical comorbidity responded more slowly and less often - particularly in domains of anxiety, global severity, and functioning (all p-values <.005). More intensive assessment and integrated treatment approaches are needed to facilitate treatment responses for depressive disorders in people with physical comorbidity. Future comparative studies between conventional and integrated treatment approaches are indicated for depressive disorders with physical comorbidity.Journal of psychosomatic research 11/2011; 71(5):311-8.
