Factors associated with changes in quality of life of COPD patients: a prospective study in primary care.

BACKGROUND: A primary objective in the treatment of patients with chronic obstructive pulmonary disease (COPD) is to improve their health status. OBJECTIVE: To identify the factors associated with changes in health-related quality of life (HRQoL) in patients with COPD after one year of follow-up in primary care. METHOD: Multicenter, prospective study with one year of follow-up. The end-point was the change in total score on the Saint George's Respiratory Questionnaire (SGRQ). Patients with a clinically relevant (>4 points) decrease or increase in SGRQ total score were compared. Factors associated with the changes in HRQoL observed after one year were determined by logistic regression analysis. RESULTS: A total of 791 patients (mean age, 70.2 years) were analyzed. Mean FEV1 (% predicted) was 52.4%. Average total SGQR score was 37.1 (SD = 19.1) at baseline and 35.6 (SD = 18.9) at follow-up. Significantly improved HRQoL was observed in 36.7% of patients, and was associated with starting polymedication, pulmonology visits, and balanced diet; ending respiratory rehabilitation, quitting smoking; and not being a frequent exacerbator. Quality of life worsened significantly in 29.2% of patients, and was associated with worsening respiratory symptoms and increased hospital admissions. CONCLUSIONS: Although overall changes in HRQoL observed after one year were minimal, more than one third of patients improved significantly, and one third had significantly worse HRQoL. Clinical factors were independently associated with these changes, emphasizing the relevance to improved HRQoL of starting a healthy lifestyle and respiratory treatments and the negative impact on HRQoL of COPD symptoms onset and admissions.

Effect of health professional education on outcomes of chronic obstructive pulmonary disease in primary care: a non-randomized clinical trial.

BACKGROUND AND OBJECTIVE: The best strategy to achieve optimal integrated management to patients with chronic obstructive pulmonary disease (COPD) in primary care (PC) is not clear. We aimed to evaluate the effectiveness of an intervention in PC based on an integrated programme, which combines diverse strategies directed at health professionals to improve quality of life and clinical outcomes of their patients with COPD. We compared the outcome with results from standard practice. METHODS: A prospective, multicentre, quasi-experimental study and a 12-month follow up was performed. Intervention consisted of an integrated education programme in PC. The main outcome variable was the change in total score of the St. George's Respiratory Questionnaire (SGRQ) at the end of follow up between the control and intervention group. RESULTS: A total of 801 patients participated in the study with a mean age of 70.2 years and a mean FEV1 (% predicted) of 55%. At 1-year follow up, the SGRQ score did not significantly differ. Although the intervention group showed an improvement in dietary, exercise and smoking habits, there was an increase in reported exacerbations and hospital admissions (P < 0.001). CONCLUSIONS: Implementation of an integrated education programme in a PC setting, which combines diverse strategies directed at health professionals, did not achieve the expected changes in quality of life measured by SGRQ at 1-year follow up. Nonetheless, this study observed an improvement in patients' lifestyle choices, even though this did not result in a significant change in the clinical evolution or heath status over 12 months.

Evaluation of a combined strategy directed towards health-care professionals and patients with chronic obstructive pulmonary disease (COPD): information and health education feedback for improving clinical monitoring and quality-of-life.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a health problem that is becoming increasingly attended-to in Primary Care (PC). However, there is a scarcity of health-care programs and studies exploring the implementation of Clinical Practice Guidelines (CPG). The principal objective of the present study is to evaluate the effectiveness of a combined strategy directed towards health-care professionals and patients to improve the grade of clinical control and the quality-of-life (QoL) of the patients via a feedback on their state-of-health. A training plan for the health-care professionals is based on CPG and health education. METHOD/DESIGN: Multi-centred, before-after, quasi experimental, prospective study involving an intervention group and a control group of individuals followed-up for 12 months. The patients receive attention from urban and semi-urban Primary Care Centres (PCC) within the administrative area of the Costa de Ponent (near Barcelona). All the pacients corresponding to the PCC of one sub-area were assigned to the intervention group and patients from the rest of sub-areas to the group control. The intervention includes providing data to the health-care professionals (clinician/nurse) derived from a clinical history and an interview. A course of training focused on aspects of CPG, motivational interview and health education (tobacco, inhalers, diet, physical exercise, physiotherapy). The sample random includes a total of 801 patients (> or = 40 years of age), recorded as having COPD, receiving attention in the PCC or at home, who have had at least one clinical visit, and who provided written informed consent to participation in the study. Data collected include socio-demographic characteristics, drug treatment, exacerbations and hospital admissions, evaluation of inhaler use, tobacco consumption and life-style and health-care resources consumed. The main endpoints are dyspnoea, according to the modified scale of the Medical Research Council (MRC) and the QoL, evaluated with the St George's Respiratory Questionnaire (SGRQ). The variables are obtained at the start and the end of the intervention. Information from follow-up visits focuses on the changes in life-style activities of the patient. DISCUSSION: This study is conducted with the objective of generating evidence that shows that implementation of awareness programs directed towards health-care professionals as well as patients in the context of PC can produce an increase in the QoL and a decrease in the disease exacerbation, compared to standard clinical practice.
