Background Adoption and maintenance of healthy behaviours is pivotal to chronic disease self-management as this influences disease progression and impact. This qualitative study investigated health behaviour changes adopted by participants with moderate or severe chronic obstructive pulmonary disease (COPD) recruited to a randomised controlled study of telephone-delivered health-mentoring. Methods Community nurses trained as health-mentors used a patient-centred approach with COPD patients recruited in general practice to facilitate behaviour change, using a framework of health behaviours; ‘SNAPPS’ Smoking, Nutrition, Alcohol, Physical activity, Psychosocial well-being, and Symptom management, through regular phone calls over 12 months. Semi-structured interviews in a purposive sample sought feedback on mentoring and behaviour changes adopted. Interviews were analysed using iterative thematic and interpretative content approaches by two investigators. Results Of 90 participants allocated to health-mentoring, 65 (72%) were invited for interview at 12-month follow up. The 44 interviewees, 75% with moderate COPD, had a median of 13 mentor contacts over 12 months, range 5–20. Interviewed participants (n = 44, 55% male, 43% current smokers, 75% moderate COPD) were representative of the total group with a mean age 65 years while 82% had at least one additional co-morbid chronic condition. Telephone delivery was highly acceptable and enabled good rapport. Participants rated ‘being listened to by a caring health professional’ as very valuable. Three participant groups were identified by attitude to health behaviour change: 14 (32%) actively making changes; 18 (41%) open to and making some changes and 12 (27%) more resistant to change. COPD severity or current smoking status was not related to group category. Mentoring increased awareness of COPD effects, helping develop and personalise behaviour change strategies, even by those not actively making changes. Physical activity was targeted by 43 (98%) participants and smoking by 14 (74%) current smokers with 21% reporting quitting. Motivation to maintain changes was increased by mentor support. Conclusions Telephone delivery of health-mentoring is feasible and acceptable to people with COPD in primary care. Health behaviours targeted by this population, mostly with moderate disease, were mainly physical activity and smoking reduction or cessation. Health-mentoring increased motivation and assisted people to develop strategies for making and sustaining beneficial change. Trial registration ACTR12608000112368

The growing burden of chronic disease will increase the role of primary care in supporting self-management and health behaviour change. This role could be undertaken to some extent by the increased practice nurse workforce that has occurred over recent years. Mixed methods were used to investigate the potential for general practice nurses to adopt this role during a 12-month randomised controlled study of telephone-delivered health mentoring in Tasmanian practices. Nurses (general practice and community health) were trained as health mentors to assist chronic obstructive pulmonary disease patients to identify and achieve personal health related goals through action plans. Of 21% of invited practices that responded, 19 were allocated to health mentoring; however, general practice nurses were unable to train as health mentors in 14 (74%), principally due to lack of financial compensation and/or workload pressure. For five general practice nurses trained as health mentors, their roles had previously included some chronic disease management, but training enhanced their understanding and skills of self-management approaches and increased the focus on patient partnership, prioritising patients’ choices and achievability. Difficulties that led to early withdrawal of health mentors were competing demands, insufficient time availability, phone calls having lower priority than face-to-face interactions and changing employment. Skills gained were rated as valuable, applicable to all clinical practice and transferable to other health care settings. Although these results suggest that training can enhance general practice nurses’ skills to deliver self-management support in chronic disease, there are significant system barriers that need to be addressed through funding models and organisational change.

Late asthmatic reactions can be difficult to recognize because of their prolonged time course and the confounding effects of superimposed circadian rhythms of ventilatory function. Conventional methods of analysis are rather arbitrary. They depend for example on a 15 or 20% fall in forced expiratory volume in one second (FEV 1 ) from baseline or from time-matched control measurements. We have, therefore, investigated whether statistical approaches applied to individual subjects can assist in the identification of late asthmatic reactions.In two separate series of aerosol inhalation tests, three symptomatic workers, three asthmatic controls and three nonasthmatic controls were challenged blindly with increasing doses of two chemical agents, and saline. One of the agents, sodium isononanoyl oxybenzene sulphonate (SINOS) was a suspected cause of occupational asthma. Prior to the challenges, FEV 1 was measured hourly on three control days. Cumulative late changes on both control and active challenge days were quantified as the area between a line extrapolated from a 10.00 h baseline and the actual measurements from 12.00-22.00 h (the 2-12 h area decrement). The area decrement measurements on control and active challenge days were compared using Student's t-tests. The sensitivity of this method for detecting late asthmatic reactions among potentially positive tests (SINOS challenge tests in the workers) was examined, as was its specificity. The latter was determined from the false positive rate among the negative tests. A second statistical method based on the pooled standard deviation of serial (hourly) FEV 1 measurements was investigated in the same way. In total, the data from 220 challenge and 30 control days were available for analysis.Late responses associated with falls in FEV 1 of 8-16% were statistically significant when a t-test was used to compare area decrement on each active challenge day with three control days. This approach was, therefore, potentially more sensitive than conventional techniques for identifying late asthmatic reactions. The false positive rate was 4%. The serial FEV 1 method was more sensitive, identifying a further five positive tests, but was less specific, with a false positive rate of 7%.These results suggest that when the day-to-day variability of lung function has been estimated from at least three control days, statistical tests can be applied to potential late asthmatic reactions, allowing them to be identified with greater precision than conventional clinical techniques.
