Associations between chronic comorbidity and exacerbation risk in primary care patients with COPD

BackgroundCOPD often coexists with chronic conditions that may influence disease prognosis. We investigated associations between chronic (co)morbidities and exacerbations in primary care COPD patients.MethodRetrospective cohort study based on 2012–2013 electronic health records from 179 Dutch general practices. Comorbidities from patients with physician-diagnosed COPD were categorized according to International Classification of Primary Care (ICPC) codes. Chi-squared tests, uni- and multivariable logistic, and Cox regression analyses were used to study associations with exacerbations, defined as oral corticosteroid prescriptions.ResultsFourteen thousand six hundred three patients with COPD could be studied (mean age 67 (SD 12) years, 53% male) for two years. At baseline 12,826 (88%) suffered from ≥1 comorbidities, 3263 (22%) from ≥5. The most prevalent comorbidities were hypertension (35%), coronary heart disease (19%), and osteoarthritis (18%). Several comorbidities showed statistically significant associations with frequent (i.e., ≥2/year) exacerbations: heart failure (odds ratio [OR], 95% confidence interval: 1.72; 1.38–2.14), blindness & low vision (OR 1.46; 1.21–1.75), pulmonary cancer (OR 1.85; 1.28–2.67), depression 1.48; 1.14–1.91), prostate disorders (OR 1.50; 1.13–1.98), asthma (OR 1.36; 1.11–1.70), osteoporosis (OR 1.41; 1.11–1.80), diabetes (OR 0.80; 0.66–0.97), dyspepsia (OR 1.25; 1.03–1.50), and peripheral vascular disease (OR 1.20; 1.00–1.45). From all comorbidity categories, having another chronic respiratory disease beside COPD showed the highest risk for developing a new exacerbation (Cox hazard ratio 1.26; 1.17–1.36).ConclusionChronic comorbidities are highly prevalent in primary care COPD patients. Several chronic comorbidities were associated with having frequent exacerbations and increased exacerbation risk.

Feasibility and effectiveness of an asthma/COPD service for primary care: a cross-sectional baseline description and longitudinal results.

Background:In 2007, an Asthma/chronic obstructive pulmonary disease (COPD) (AC) service was implemented in the North of the Netherlands to support General Practitioners (GPs) by providing advice from pulmonologists on a systematic basis.Aims:To evaluate the feasibility and effectiveness of this service on patient-related outcomes.Methods:We report baseline data on 11,401 patients and follow-up data from 2,556 patients. GPs can refer all patients with possible obstructive airway disease (OAD) to the service, which is conducted by the local laboratory. Patients are assessed in the laboratory using questionnaires and spirometry. Pulmonologists inspect the data through the internet and send the GP diagnosis and management advice.Results:A total of 11,401 patients were assessed by the service, covering almost 60% of all adult patients with projected asthma or COPD in the area. In all, 46% (n=5,268) of the patients were diagnosed with asthma, 18% (n=2,019) with COPD and 7% (n=788) with the overlap syndrome. A total of 740 (7%) patients were followed up after 3 months because the GP advised them to change medication. In this group, the proportion of unstable COPD patients (Clinical COPD Questionnaire (CCQ)⩾1) decreased from 63% (n=92) at baseline to 49% (n=72). The proportion of patients with uncontrolled asthma (Asthma Control Questionnaire (ACQ)⩾1.5) decreased from 41% (n=204) to 23% (n=115). In all, 938 (8%) patients were followed up after 12 months. From these patients, the proportion of unstable COPD patients (CCQ⩾1) decreased from 47% (n=115) to 44% (n=107). The proportion of patients with uncontrolled asthma (ACQ⩾1.5) decreased from 16% (n=95) to 14% (n=85).Conclusion:The AC service assessed a considerable proportion of patients with OAD in the area, improved patients’ outcomes, and is considered to be feasible and effective.

Morning and night symptoms in primary care COPD patients: a cross-sectional and longitudinal study. An UNLOCK study from the IPCRG.

COPD symptoms show a diurnal variability. However, morning and night variability has generally not been taken into consideration in disease management plans. The aims of this study were to cross-sectionally assess morning and night symptom prevalence and correlation with health status and disease severity in COPD, and to determine to what extent they could predict longitudinal outcomes, exacerbations and health status. A further aim is to explore whether the CCQ is able to depict this morning/night symptomatology. We included 2,269 primary care COPD patients (58% male, 49% current smokers, with a mean age of 65±11 years) from a Dutch Asthma/COPD service. Spirometry, patient history, the Clinical COPD Questionnaire(CCQ) and the Asthma Control Questionnaire(ACQ) were assessed; we used the latter to evaluate morning (question 2) and night symptoms (question 1). A total of 1159 (51.9%) patients reported morning symptoms (ACQ question 2>0) and 879 (39.4%) had night complaints (ACQ question 1>0). Patients with morning/night symptoms were mostly smokers and had on average poorer lung function, higher CCQ scores and used more rescue inhalers (P<0.0001). Patients using long-acting muscarinic antagonists (LAMAs) had less night symptoms, showing a possible favourable effect. Only a small proportion of stable or slightly unstable patients (CCQ total scores <2) had severe morning symptoms (ACQ 2⩾4: n=19, 1.1%) or severe night symptoms (ACQ 1⩾4: n=11, 0.7%). Night symptoms seemed to predict future exacerbations; however, baseline exacerbations were the strongest predictors (n=346, OR:4.13, CI: 2.45−6.95, P<0.000). Morning symptoms increased the odds of poor health status at follow-up (n=346, OR:12.22, CI:4.76−31.39, P<0.000). Morning and night symptoms in COPD patients are common, and they are associated with poor health status and predicted future exacerbations. Our study showed that patients with morning/night symptoms have higher scores in CCQ, and therefore we do not really miss patients with high morning/night symptomatology when we only measure CCQ. Severe morning symptoms predicted worsening of COPD health status.

Needs and perspectives of patients with asthma and chronic obstructive pulmonary disease on patient web portals: a focus group study (Preprint)

Background As accessibility to the internet has increased in society, many health care organizations have developed patient Web portals (PWPs), which can provide a range of self-management options to improve patient access. However, the available evidence suggests that they are used inefficiently and do not benefit patients with low health literacy. Asthma and chronic obstructive pulmonary disease (COPD) are common chronic diseases that require ongoing self-management. Moreover, patients with COPD are typically older and have lower health literacy. Objective This study aimed to obtain and present an overview of patients’ perspectives of PWPs to facilitate the development of a portal that better meets the needs of patients with asthma and COPD. Methods We performed a focus group study using semistructured interviews in 3 patient groups from the north of the Netherlands who were recruited through the Dutch Lung Foundation. Each group met 3 times for 2 hours each at a 1-week interval. Data were analyzed with coding software, and patient descriptors were analyzed with nonparametric tests. The consolidated criteria for reporting qualitative research were followed when conducting the study. Results We included 29 patients (16/29, 55% male; mean age 65 [SD 10] years) with COPD (n=14), asthma-COPD overlap (n=4), asthma (n=10), or other respiratory disease (n=1). There was a large variation in the internet experience; some patients hardly used the internet (4/29, 14%), whereas others used internet >3 times a week (23/29, 79%). In general, patients were positive about having access to a PWP, considering access to personal medical records as the most important option, though only after discussion with their physician. A medication overview was considered a useful option. We found that communication between health care professionals could be improved if patients could use the PWP to share information with their health care professionals. However, as participants were worried about the language and usability of portals, it was recommended that language should be adapted to the patient level. Another concern was that disease monitoring through Web-based questionnaire use would only be useful if the results were discussed with health care professionals. Conclusions Participants were positive about PWPs and considered them a logical step. Today, most patients tend to be better educated and have internet access, while also being more assertive and better informed about their disease. A PWP could support these patients. Our participants also provided practical suggestions for implementation in current and future PWP developments. The next step will be to develop a portal based on these recommendations and assess whether it meets the needs of patients and health care providers.
