Chronic Obstructive Pulmonary Disease: Patients´ Perspectives, Impact of the Disease and Utilization of Spirometry
Uppsala University, Disciplinary Domain of Medicine and Pharmacy, Faculty of Medicine, Department of Medical Sciences, Respiratory Medicine and Allergology.
2010 (English)Doctoral thesis, comprehensive summary (Other academic)
Abstract [en]

The overall aim of this thesis was to describe subjects with chronic obstructive pulmonary disease (COPD) from different perspectives. Focus was on patients at the time of diagnosis, impact of the disease in comparison to other chronic diseases, factors associated with good health and quality of life (QoL), and diagnostic spirometry in clinical practice.

Methods: Qualitative method, grounded theory, was used to analyse patients´ perspectives at the time of diagnosis in a primary care setting (n=10). Public health surveys in the general population were used to compare chronic diseases (n=10,755) and analyse factors associated with health outcomes in COPD (n=1,475). Medical records and spirometry reports, from primary and secondary care, were analysed to assess diagnosis of COPD in clinical practice (n=533).

Results: In clinical practice, 70% of patients at the time of diagnosis of COPD lacked spirometry results confirming the diagnosis. Factors related to consequences of smoking, shame and restrictions in physical activity (PA) in particular, were described by patients at the time of diagnosis of COPD. In general subjects with COPD (84%), rheumatoid arthritis (74%) and diabetes mellitus (72%) had an activity level considered too low to maintain good health. In COPD, the most important factor associated with good health and quality of life was a high level of PA. Odds ratios (OR (95%CI)) varied from 1.90 (1.47-2.44) to 7.57 (4.57-12.55) depending on the degree of PA, where subjects with the highest PA level had the best health and QoL.

Conclusions: Subjects with COPD need to be diagnosed at an early stage, and health professionals should be aware that feelings of shame could delay patients from seeking care and thus obtaining a diagnosis. The use of spirometry and the diagnostic quality should be emphasised. In patients with COPD greater attention should be directed on increasing the physical activity level, as patients with a low level of physical activity display worse health and quality of life.

Abstract [en]

Aims: To gain understanding of chronic obstructive pulmonary disease (COPD) patients´ perspectives and perceptions of their disease at the time of diagnosis. Methods: Qualitative study; grounded theory. Ten patients in primary care in Sweden, newly diagnosed with COPD or diagnosed with suspected COPD were interviewed. Results: The analysis created a process model with a core category “Consequences of smoking” and main categories “Shame”, “Appearance of symptoms”, “Adaptation”, “Reflection”, and “Action”. “Restrictions in physical capacity” was a key indicator of evolving disease and “Getting a diagnosis” was crucial for the patient. Conclusions: The COPD patient needs a clear diagnosis at an early stage. It is important to seize the moment when the presumptive COPD patient is receptive towards support and further action. To detect and support the patient, health professionals must be aware of minor symptoms and underlying mechanisms of possible shame.

Abstract [en]

OBJECTIVE: Chronic diseases interfere with the life situation of the affected person in different ways. The aim was to compare the burden of disease in three chronic diseases - chronic obstructive pulmonary disease (COPD), rheumatoid arthritis (RA), diabetes mellitus (DM) - and in healthy subjects, with a particular interest in physical activity, quality of life, and psychological health. DESIGN: Cross-sectional, observational study. SETTING AND SUBJECTS: Postal survey questionnaire to a stratified, random population of 68 460 subjects aged 18-84 years in Sweden. The subjects included were 40-84 years old (n = 43 589) and data were analysed for COPD (n = 526), RA (n = 1120), DM (n = 2149) and healthy subjects (n = 6960). RESULT: Some 84% of subjects with COPD, 74% (RA), 72% (DM), and 60% in healthy subjects (p < 0.001, COPD versus RA, DM, and healthy subjects) had a physical activity level considered too low to maintain good health according to guidelines. Quality of life (EuroQol five-dimension questionnaire, EQ-5D) was lower in COPD and RA than in DM. Anxiety/depression was more common in subjects with COPD (53%) than in those with RA (48%) and DM (35%) (p < 0.001, COPD versus RA and DM), whereas mobility problems were more common in RA (55%) than COPD (48%) and DM (36%) (p < 0.001, RA versus COPD and DM). All differences between groups remained significant after adjusting for age, sex, and socioeconomic background factors. CONCLUSION: Subjects with chronic diseases had a low level of physical activity, most evident in subjects with COPD. COPD and RA had a higher negative impact on quality of life than DM. Our results indicate that increased attention regarding physical inactivity in subjects with chronic diseases is needed to minimize the burden of disease.

2011 (English)In: The International Journal of Chronic Obstructive Pulmonary Disease, ISSN 1176-9106, E-ISSN 1178-2005, Vol. 6, p. 511-519Article in journal (Refereed) Published
Abstract [en]

Background: Recent guidelines for chronic obstructive pulmonary disease (COPD) state that COPD is both preventable and treatable. To gain a more positive outlook on the disease it is interesting to investigate factors associated with good, self-rated health and quality of life in subjects with self-reported COPD in the population.

Methods: In a cross-sectional study design, postal survey questionnaires were sent to a stratified, random population in Sweden in 2004 and 2008. The prevalence of subjects (40–84 years) who reported having COPD was 2.1% in 2004 and 2.7% in 2008. Data were analyzed for 1475 subjects. Regression models were used to analyze the associations between health measures (general health status, the General Health Questionnaire, the EuroQol five-dimension questionnaire) and influencing factors.

Results: The most important factor associated with good, self-rated health and quality of life was level of physical activity. Odds ratios for general health varied from 2.4 to 7.7 depending on degree of physical activity, where subjects with the highest physical activity level reported the best health and also highest quality of life. Social support and absence of economic problems almost doubled the odds ratios for better health and quality of life.

Conclusions: In this population-based public health survey, better self-rated health status and quality of life in subjects with self-reported COPD was associated with higher levels of physical activity, social support, and absence of economic problems. The findings indicated that of possible factors that could be influenced, promoting physical activity and strengthening social support are important in maintaining or improving the health and quality of life in subjects with COPD. Severity of the disease as a possible confounding effect should be investigated in future population studies.

Abstract [en]

Background: Chronic obstructive pulmonary disease (COPD) is an important cause of morbidity and mortality worldwide. Diagnosis is customarily confirmed with spirometry, but there are few studies on documented spirometry use in everyday clinical practice. Methods: In a cross-sectional survey and study of the medical records of primary and secondary care COPD patients aged 18-75 in a Swedish region, patients with COPD were randomly selected from the registers of 56 primary care centres and 14 hospital outpatient clinics. Spirometry data at diagnosis ±6 months were analyzed. Results: From 1,114 patients with COPD, 533 with a new diagnosis of COPD during the four-year study period were identified. In 59% (n=316), spirometry data in connection with diagnosis were found in the medical records. Spirometry data with post-bronchodilator forced expiratory volume in one second (FEV1)/ vital capacity (VC) ratios were available in 45% (n=241). FEV1/VC ratio <0.70 were found in 160 patients, which corresponds to 30% of the patients with a new diagnosis. Lower age, female gender, current smoking, higher body mass index (BMI) and shorter forced exhalation time were related to COPD diagnosis despite an FEV1/VC ratio of ≥0.70. The most common problem in the quality assessment was an insufficient exhalation time. Conclusions: Only a third of Swedish patients with COPD had their diagnosis confirmed with spirometry. Our data indicate that female gender, current smoking, higher BMI and short exhalation time increase the risk of being diagnosed with COPD without fulfilling the spirometric criteria for the disease.
