This level is the aggregate of the physicians' target profile, physicians' (sub-) competencies to be achieved and the list of issues relating to illness and health.

Self-management is a term applied to educational programmes aimed at teaching skills needed to carry out medical regimens specific to the disease, guide health behaviour change, and provide emotional support for patients to control their disease and live functional lives.

This report describes the quality control programme used within the Bronchitis Randomized on N-acetylcysteine (NAC) Cost-Utility Study, a trial designed to assess the decline in lung function, exacerbation rate, health status, and cost-effectiveness with NAC or a placebo in 523 patients with chronic obstructive pulmonary disease over a 3-yr period. Spirometry was scored from 0 (worst quality) to 6 (best quality). The mean score of 314 spirometries from 243 patients evaluated during the trial was 5.

Aims: The main objective of this study was to investigate whether a comprehensive self-management programme, including self-treatment guidelines for exacerbations and a fitness programme, is an efficient treatment option for chronic obstructive pulmonary disease (COPD) patients.

Method: We randomly allocated 248 COPD patients to either self-management (127) or usual care (121). Data on preference-based utilities (EuroQol-5D), health-related quality of life (HRQoL), health-care resource use and productivity losses associated with exacerbations were prospectively collected.
