All patients admitted for the first time to the hospital between 1999 and 2014 with a diagnosis of AECOPD, age 35– 59, without a previous asthma diagnosis were included in the study. Employment status effect on 30-, 90-, and 365-day readmission and mortality was examined using logistic regression, adjusting for relevant confounders.Results: A total of 11,850 COPD patients were included in the study of which 3563 (30%) were working, 1368 (12%) unemployed, 840 (7%) on sick leave, and 6079 (51%) receiving early retirement. Patients receiving early retirement had, compared to patients working, an adjusted increased likelihood of readmission at 30, 90, and 365 days (odds ratio (OR) 1.26 (CI95% (1.06– 1.49)), 1.33 (CI95% (1.16– 1.53)), and 1.48 (CI95% (1.33– 1.66)), respectively). An increased likelihood was also seen in unemployed at 365 days follow-up (OR 1.44 (CI95% (1.22– 1.68))). Early retirement was associated with an increased mortality at 30, 90, and 365 days (OR 1.39 (CI95% (1.07– 1.80)) 1.37 (CI95% (1.09– 1.79)) and 1.48 (CI95% (1.25– 1.75)), respectively). An increased likelihood was also seen in patients receiving sick leave (OR 1.57 (CI95% (1.21– 2.04))).Conclusion: Patients with COPD who are not working at the time of first admission have a higher likelihood of readmission and mortality.Keywords: chronic obstructive pulmonary disease, employment, mortality, readmission

Gender-related differences in patients with COPD are known, for instance regarding symptoms and quality of life. Yet, research regarding gender differences in partners of patients with COPD has been conducted to a lesser extent, and most research focused on female partners. We aimed to investigate differences between male and female partners of patients with COPD regarding their own characteristics and their perceptions of patients’ characteristics.Design: Cross-sectional study.Setting: Four hospitals in the Netherlands.Participants: One hundred and eighty-eight patient–partner couples were included in this cross-sectional study.Measurements: General and clinical characteristics, health status, care dependency, symptoms of anxiety and depression, social support, caregiver burden, and coping styles were assessed during a home visit.Results: Female partners had more symptoms of anxiety and a worse health status than male partners. Social support and caregiver burden were comparable, but coping styles differed between male and female partners. Female partners thought that male patients were less care dependent and had more symptoms of depression, while these gender differences did not exist in patients themselves.Conclusion: Health care providers should pay attention to the needs of all partners of patients with COPD, but female partners in particular. Obtaining an extensive overview of the patient–partner couple, including coping styles, health status, symptoms of anxiety, and caregiver burden, is necessary to be able to support the couple as effectively as possible.

Yet, the prevalence of cognitive impairment in specific cognitive domains in COPD has been poorly studied. The aim of this cross-sectional observational study was to compare the prevalence of domain-specific cognitive impairment between patients with COPD and non-COPD controls. A neuropsychological assessment was administered in 90 stable COPD patients and 90 non-COPD controls with comparable smoking status, age, and level of education. Six core tests from the Maastricht Aging Study were used to assess general cognitive impairment. By using Z-scores, compound scores were constructed for the following domains: psychomotor speed, planning, working memory, verbal memory, and cognitive flexibility. General cognitive impairment and domain-specific cognitive impairment were compared between COPD patients and controls after correction for comorbidities using multivariate linear and logistic regression models. General cognitive impairment was found in 56.7% of patients with COPD and in 13.3% of controls. Deficits in the following domains were more often present in patients with COPD after correction for comorbidities: psychomotor speed (17.8% vs 3.3%; P
