"Can Do" Versus "Do Do" in Patients with Asthma at First Referral to a Pulmonologist.

BACKGROUND: Pharmacotherapy is key in asthma control, including preventing lung function decline, in primary care. However, patients' physical functioning (eg, physical capacity [PC] [=can do] and physical activity [PA] [=do do]) correlates poorly with lung function. Therefore, a better insight into the physical function of patients with asthma is needed, using the "can do, do do" concept. OBJECTIVE: To explore the "can do, do do" concept in adult patients with asthma at referral for the first time to an outpatient consultation of a pulmonologist. METHODS: PC was measured using the six-minute walk test and PA by using an accelerometer. Patients were classified into quadrants: low PC (6-minute walking distance <70% predicted), low PA (<7000 steps/d, "'can't do, don't do"); preserved PC, low PA ("can do, don't do"); low PC, preserved PA ("'can't do, do do"); or preserved PC, preserved PA ("can do, do do"). RESULTS: A total of 479 patients with asthma had a median (interquartile range) 6-minute walking distance of 74% (66%-82%) predicted, and walked 6829 (4593-9075) steps/d. Only 29% were classified as "can do, do do," whereas 30% were classified as "can't do, don't do." The Asthma Control Questionnaire and the Asthma Quality of Life Questionnaire scores were worst in the "can't do" groups. CONCLUSIONS: Low PC and/or PA was found in most patients with asthma at the index referral to a pulmonologist. An impaired PC is accompanied by a significantly reduced asthma control and disease-specific quality of life. This justifies further studies on safety and efficacy of nonpharmacological interventions, such as physiotherapy.

Evaluation of the COPDnet integrated care model in patients with COPD: the study protocol.

Background: Projections on the future suggest a further rise in the prevalence of patients with COPD, and in COPD related morbidity, mortality, and health care costs worldwide. Given the substantial impact on the individual and on society, it is important to establish a care process that maximizes outcomes in relation to the costs and efforts made. In an attempt to bridge this gap, we set out to develop an evidence-based model of integrated care for patients with COPD, named the COPDnet integrated care model. Purpose: The current study protocol sets out to 1) evaluate the feasibility of employing the COPDnet model in present real-life care within the context of the Dutch health care system, 2) explore the potential health status benefits, and 3) analyze the costs of care of this model. Patients and methods: In this prospective study, feasibility and health status changes will be evaluated with an experimental before and after study design. The costs of the diagnostic trajectory will be calculated according to a standard economic health care evaluation approach. Furthermore, the feasibility and cost of care studies will comprise both quantitative and qualitative data collection. For the studies on the feasibility and change in health status, all new patients qualifying for shared care by primary and secondary care professionals according to the Dutch Standard of Care for COPD, and patients referred by their general practitioners to one of the COPDnet hospitals will be included. To evaluate the feasibility and costs of care, semi-structured interviews will be held with patients, hospital personnel, health care professionals in the affiliated primary care region, and hospital and primary care group managers. Conclusions: The COPDnet integrated care model for COPD patients has been designed according to the current insights regarding effective care for patients with a chronic condition in general, and for patients with COPD in particular. It will be evaluated for its feasibility, potential health status benefits, and the costs of care of the diagnostic trajectory in secondary care.

The COPDnet integrated care model.

Introduction: This research project sets out to design an integrated disease management model for patients with COPD who were referred to a secondary care setting and who qualified for pharmacological and nonpharmacological intervention options. Theory and methods: The integrated disease management model was designed according to the guidelines of the European Pathway Association and the content founded on the Chronic Care Model, principles of integrated disease management, and knowledge of quality management systems. Results: An integrated disease management model was created, and comprises 1) a diagnostic trajectory in a secondary care setting, 2) a nonmedical intervention program in a primary care setting, and 3) a pulmonary rehabilitation service in a tertiary care setting. The model also includes a quality management system and regional agreements about exacerbation management and palliative care. Discussion: In the next phase of the project, the COPDnet model will be implemented in at least two different regions, in order to assess the added value of the entire model and its components, in terms of feasibility, health status benefits, and costs of care. Conclusion: Based on scientific theories and models, a new integrated disease management model was developed for COPD patients, named COPDnet. Once the model is stable, it will be evaluated for its feasibility, health status benefits, and costs.

Comprehensive Diagnostic Assessment of Health Status of Patients with Asthma or COPD: A Delphi Panel Study among Dutch Experts.

A comprehensive diagnostic assessment is needed to improve understanding of the health status of patients with chronic obstructive pulmonary disease (COPD) or asthma. Therefore, this study investigated which components and subsequent instruments should be part of a holistic assessment in secondary care. We also explored which data need to be exchanged for an adequate transfer of patients between primary and secondary care, and vice versa. A cross-sectional Web-based survey was conducted among Dutch healthcare professionals using a Delphi-like procedure; these included professionals working in primary or secondary care, medical advisors of health insurance companies and patients' representatives. The national guidelines were used as a starting point, resulting in a questionnaire addressing 55 components related to a comprehensive diagnostic assessment, covering the domains physiological impairments, symptoms, functional limitations and quality of life. Of the 151 experts and stakeholders invited, 92 (60.9%) completed the first round and 79 (52.3%) the second round; most respondents were pulmonologists. There was a high level of agreement between respondents from primary versus secondary care regarding which components should be measured during a comprehensive assessment of patients with asthma or COPD in secondary care and the instruments to measure these components. Regarding the exchange of information, upon referral, pulmonologists required little information from the general practitioners, whereas general practitioners required more extensive information after referral. An overview is provided of what should be part of a holistic assessment of health status in asthma and COPD. This information can be used as input for integrated care pathways.

Development of an integral assessment approach of health status in patients with obstructive airway diseases: the CORONA study.

BACKGROUND: Traditional assessment of patients with obstructive lung diseases (asthma and chronic obstructive pulmonary disease; COPD) relies on physiological tests. The COPD and Asthma Rotterdam Integrated Care Approach (CORONA) study aims to develop a diagnostic pathway with a more comprehensive approach to the assessment of patients with asthma and COPD in secondary care. METHODS: An eight-step method was used to develop and implement the pathway for patients with asthma or COPD referred to an outpatient hospital setting. RESULTS: The diagnostic pathway consists of an evidence-based set of measurements prioritized by a Delphi procedure. The pathway incorporates three innovative diagnostics: the metronome-paced hyperventilation test to measure dynamic hyperinflation, an activity monitor to objectively evaluate physical activity in daily life, and the Nijmegen Clinical Screening Instrument as a comprehensive assessment tool to acquire detailed insight into symptoms, functional limitations, and quality of life. CONCLUSION: An innovative diagnostic pathway was developed and implemented for patients with obstructive lung diseases referred to secondary care. As this pathway aims to provide a comprehensive analysis of health status, it focuses on biomedical aspects and also reviews behavioral aspects that further elucidate the patient's health status. The added value of the diagnostic pathway needs to be determined from both an organizational perspective and from the individual patient's viewpoint.
