[Dyspnea and quality of life in chronic obstructive pulmonary disease]

[Treating COPD in chronic patients in a primary-care setting]

The aging of the populations in Western countries entails an increase in chronic diseases, which becomes evident with the triad of age, comorbidities and polymedication. chronic obstructive pulmonary disease represents one of the most important causes of morbidity and mortality, with a prevalence in Spain of 10.2% in the population aged 40 to 80. In recent years, it has come to be defined not only as an obstructive pulmonary disease, but also as a systemic disease. Some aspects stand out in its management: smoking, the main risk factor, even though avoidable, is an important health problem; very important levels of underdiagnosis and little diagnostic accuracy, with inadequate use of spirometry; chronic patient profile; exacerbations that affect survival and cause repeated hospitalizations; mobilization of numerous health-care resources; need to propose integral care (health-care education, rehabilitation, promotion of self-care and patient involvement in decision-making).

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 (≥ 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.

Determinants and predictors of the cost of COPD in primary care: a Spanish perspective

Objectives

1) To estimate the annual cost of patients with stable chronic obstructive pulmonary disease (COPD) followed in primary care in Spain; 2) To analyze the possible cost predictor variables.

Patients and methods

A multicenter, epidemiological, observational, descriptive study. Sociodemographic data, severity of disease, associated comorbidity, treatment followed by patients, quality of life (SF-12 questionnaire), health care resource utilization in the previous 12 months and duration of working disability due to COPD were collected.

Results

A total of 10,711 patients (75.6% men; 24.4% women) with a mean age of 67.1 ± 9.66 years were evaluated. The mean forced expiratory volume in one second (FEV₁) value was 57.4 ± 13.4%. The total cost per patient per year was €1,922.60 ± 2,306.44. The largest component of this cost was hospitalization (€788.72 ± 1,766.65), followed by cost of drugs (€492.87 ± 412.15) and visits to emergency rooms (€134.32 ± 195.44). Linear regression analysis found associated heart disease, FEV₁, physical component of quality of life, number of medical visits (primary care physician, pneumologist and emergency room), hospital admissions (frequency and duration of stay) and duration of working disability to be significant predictors of the total annual cost.

Conclusions

The total annual cost of a COPD patient followed in primary care in Spain was considered high in this study. The presence of associated heart disease, severity of airflow obstruction, physical component of quality of life, health care resource utilization and duration of work disability were found to be predictor of cost.

[Evaluation of the care of the elderly program in frail elderly individuals with COPD in primary care centers in Sabadell (Spain)]

OBJECTIVE

To evaluate the effectiveness of the "Care of the Elderly" program developed by primary care teams in improving the quality of life of frail elderly individuals with a diagnosis of chronic obstructive pulmonary disease (COPD) living in Sabadell (Spain) compared with that of patients receiving routine care.

METHOD

A quasi-experimental study with an experimental and a control group was performed in the nursing consultation service of 6 randomly selected primary care centers in Sabadell. The variables studied were quality of life measured by the EuroQuol (EQ-5D), the impact of COPD on health status measured by the St. George's respiratory questionnaire (SGRQ), the number of visits to the center and the emergency department, and hospital admissions. The study was performed over a 2-year period.

RESULTS

The mean age of the 203 patients studied was 74.94 years (standard deviation [SD] = 6.11). The intervention was not effective in improving quality of life as measured by the EQ-5D, or in reducing the impact of COPD on health status measured by the SGRQ, or the number of visits to the center and hospital admissions. A statistically significant impact was found on the number of visits to the emergency department (p = 0.03).

CONCLUSIONS

The "Care of the Elderly" program in frail elderly individuals with COPD was not effective. The present study is of use in identifying aspects that are ineffective so that nurses designing future programs and studies can include new aspects such as treatment adherence, smoking cessation, and patient satisfaction.

Efectividad del tratamiento con bromuro de tiotropio en pacientes con enfermedad pulmonar obstructiva crónica

BACKGROUND AND OBJECTIVE

We assessed the clinical and functional changes taking place in patients diagnosed of chronic obstructive pulmonary disease (COPD) who have been treated with ipratropium bromide, three months after this medicament was replaced by the new tiotropium bromide.

PATIENTS AND METHOD

A prospective intervention survey was carried out in a primary health-care area in patients who suffered from COPD who fulfilled the inclusion criteria. Before changing the treatment and three months after changing it, we carried out the following procedures: spirometry, 6 minutes walking test (6MWT) with pulsioximetry before and after the exercise, St. George Respiratory Questionnaire (SGRQ) and assessment of: patient's chronic dyspnea, degree of patient's compliance, adverse effects and degree of satisfaction with the new drug.

RESULTS

24 patients (22 males and 2 females) with a mean age of 68.54 years participated in the survey. The FVC improved a 4.92% (120 ml) [p = .27] and the FEV1, 14.16% (170 ml) [p < .001]. The degree of compliance arose from 67.54% to 96.73% (p < .001), the degree of dyspnea decreased from 4.63 to 3.89 (p = .141), the 6MWT increased in 23.79 m (p = .027) and the global mark of the SGRQ reduced (improved) in 13.35 points. There were adverse effects in 5 cases (mouth dryness in 4 patients and headache in 1 of them) and 15 patients (62.5%) said the new drug was better.

CONCLUSIONS

Most analyzed parameters had positive changes three months after changing the treatment. Tiotropium may be a valid alternative in the treatment of patients suffering from COPD in a stable stage.
