Risk of depression in patients with chronic obstructive pulmonary disease and its determinants

Background: Although it has been repeatedly suggested that chronic obstructive pulmonary disease (COPD) is associated with depression, no conclusion has so far been reached. A study was undertaken to investigate whether depression occurs more often in patients with COPD than in controls. The demographic and clinical variables associated with depression were also determined. Methods: Patients with a registered diagnosis of obstructive airway disease in general practice, aged ≥40 years, forced expiratory volume in 1 second (FEV1) <80% predicted, FEV1 reversibility ≤12%, FEV1/VC ≤ predicted – 1.64 × SD, and a history of smoking were selected. A random sample of subjects without a registered diagnosis of asthma or COPD aged 40 years or older acted as controls. Depression was assessed using the Centers for Epidemiologic Studies Depression (CES-D) scale. Results: In patients with severe COPD (FEV1 <50% predicted), the prevalence of depression was 25.0% compared with 17.5% in controls and 19.6% in patients with mild to moderate COPD. When the results were adjusted for demographic variables and comorbidity, the risk for depression was 2.5 times greater for patients with severe COPD than for controls (OR 2.5, 95% CI 1.2 to 5.4). In patients with mild to moderate COPD this increased risk of depression was not seen. Living alone, reversibility of FEV1 % predicted, respiratory symptoms and physical impairment were significantly associated with the scores on the CES-D scale. Conclusion: Patients with severe COPD are at increased risk of developing depression. The results of this study underscore the importance of reducing symptoms and improving physical functioning in patients with COPD.

Prevalence of comorbidity in patients with a chronic airway obstruction and controls over the age of 40

The goal of this study is to determine the prevalence of 23 common diseases in subjects with a chronic airway obstruction and in controls. All subjects with a known diagnosis by their general practitioner of asthma or chronic obstructive pulmonary disease (COPD), and who were 40 years and older were selected (n = 1145). Subjects who were willing to participate (n = 591) and who appeared to have an irreversible airway obstruction (n = 290) were included. To recruit controls, a random sample was taken of 676 individuals who were 40 years and older and who were not diagnosed as having asthma or COPD by their general practitioner. Of these 676 individuals 421 were willing to participate. The presence of diseases was determined by using a questionnaire. One hundred and ninety-four subjects (73%) and 229 controls (63%) were shown to be suffering from one or more (other) diseases. In both groups, locomotive diseases, high blood pressure, insomnia and heart disease were most common. Locomotive diseases, insomnia, sinusitis, migraine, depression, stomach or duodenal ulcers and cancer were significantly more common in the subject group than in the control group. For both clinical and research purposes, it is important to consider the presence of diseases in patients with a chronic airway obstruction.

The problems experienced by patients with cancer and their needs for palliative care

ObjectivesTo investigate the problems that patients experience and their met- and unmet needs for professional help. This information is necessary to tailor palliative care to patient needs.Patients and methodsPatients (n=94) with disseminated cancer completed a validated checklist with 90 potential problems and needs for palliative care (PNPC questionnaire).Main resultsOn average, patients experienced 37 problems (range 0–68) and required more professional attention for eight problems (range 0–71). The five most prevalent problems were: fatigue, heavy housework, coping with the unpredictability of the future, fear of metastases, and frustrations because I can do less than before. The five issues most in need of extra attention were: informational needs, coping with the unpredictability of the future, fear of metastases, fear of physical suffering, and difficulties remembering what was told (during consultations). Younger patients experienced more social, psychological, and financial problems. Some 10% of patients expressed a multitude of problems and needs.ConclusionsWhile patients with metastasized cancer experienced a wide variety of problems, they asked for more support for only a few specific problems. Evidently, “problems” are not synonymous with unmet needs. Therefore, not only problems but also needs for care should be assessed. A structural need for support to cope with fears of suffering and loss of autonomy was found. Ten percent of patients expressed a multitude of problems and needs and might benefit either from psychological counseling or better palliative care.

The influence of COPD on health-related quality of life independent of the influence of comorbidity.

BACKGROUND/OBJECTIVES The goal of this study was to determine the influence of chronic obstructive pulmonary disease (COPD) on health-related quality of life (HRQL) independent of comorbidity. METHODS Patients with COPD in general practice, >/=40 years, were selected. To recruit controls, a random sample of persons without COPD and >/=40 years, was taken. HRQL was assessed with the SF-36 and comorbidity was determined by questionnaire. RESULTS The influence of COPD on HRQL independent of comorbidity (represented by adjusted regression coefficients) was significant for physical functioning (-27.6), role functioning due to physical problems (-21.6), vitality (-14.4), and general health (-25.7), and was minor and not significant for social functioning (-5.6), mental health (-1.3), role functioning due to emotional problems (-2.7), and bodily pain (-2.5). Comorbidity contributed significantly to the HRQL of all domains (-7.6 to -27.1). CONCLUSIONS COPD patients can be impaired in all domains of HRQL. However, impairments in physical functioning, vitality, and general health are related to COPD and to some extent to comorbidity, while impairments in social and emotional functioning do not seem to be related to COPD, but only to comorbidity.

Assessment of the need for palliative care as perceived by individual cancer patients and their families

Palliative care should fit the needs of individual cancer patients and their families. Instruments can help to improve needs assessment. This review evaluates questionnaires for the systematic assessment of needs experienced by individual cancer patients for help, care, or support, as well as the needs of their family members.

Problems to discuss with cancer patients in palliative care: a comprehensive approach

This study presents a comprehensive overview of the problems patients experience in a palliative phase of cancer. A two-step qualitative method was used: in-depth interviews with patients and relatives (N=9 patients+7 relatives), followed by interviews (N=31patients+15 relatives) using a checklist to confirm and complete the picture. Quality of life and quality of care domains were addressed. Patients experienced problems in all of these palliative care domains, although individual patients may have experienced only a few problems. Fatigue, feelings of futility, reluctance to accept help, fear of suffering and the fear that help would not be available if needed, were common problems. Communication problems arose when a grudge against a GP had remained, or because one family member tried to spare the other a confrontation with his/her feelings of fear or grief. A comprehensive checklist of relevant problems is presented.

A practical instrument to explore patients' needs in palliative care: the Problems and Needs in Palliative Care questionnaire — short version

Objective : Short and convenient checklists are necessary tools to support and structure needs assessments in daily palliative practice. This study aims to develop a short version of the Problems and Needs in Palliative Care questionnaire (PNPC-sv); a self-report questionnaire for patients covering all dimensions of palliative care, to investigate their problems and (unmet) needs. Methods : The original Problems and Needs in Palliative Care questionnaire (PNPC) instrument is a comprehensive checklist of problems and needs for palliative care, and has shown validity and reliability. With its 90 items, however, it is not always practical. Thus it was abridged to a short version with 33 items. The validity and reliability are established with its item response, its internal consistency, and with its correlations with the original PNPC and with European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 and COOP/WONCA quality-of-life measures. A secondary analysis was done with data from 94 patients with metastatic cancer who had completed the long version. Results : Each item in the PNPC represents a problem relevant to 25% of the patients or more. High correlations of PNPC-sv and PNPC domains demonstrate construct validity. The dimension reliability was satisfactory (Cronbachs α > 0.70), while two problem-aspect domains were less coherent. The PNPC-sv domains show convergent validity with corresponding health-related quality-of-life domains. Conclusion : The PNPC-sv is a concise, patient-centred tool that helps to identify the problems affecting the patients quality of life and needs for care. It identifies prevalent needs for care and appears reliable. Further research should study the clinical effects of integrating the questionnaire into daily palliative-care practice.
