A community wide promotion of asthma self management: process evaluation.

AIMS: During the months February through July 1991, a community wide promotion of asthma self-management was undertaken as a pilot study for the national launch of an asthma action plan developed by the Asthma Foundation of New Zealand in conjunction with the Royal New Zealand College of General Practitioners. METHODS: A multidisciplinary team of hospital and community-based health workers was established, with the aim of educating and resourcing general practitioners, practice nurses and retail pharmacists to enable them to effectively promote and distribute the asthma action plan. 332 general practitioners and 148 retail pharmacists were surveyed through postal and telephone questionnaires at the completion of the promotion, to assess its impact on health professionals and to obtain feedback for the national promotion of the asthma action plan. RESULTS: 108 (73%) of pharmacists who responded and were involved with the promotion found their participation to be worthwhile, although some had difficulty allocating sufficient time to give detailed advice to patients. Of the 240 general practitioners who responded, 77% indicated that they had used the asthma action plan with their patients. They were positive about the use of the workshop format that had provided education and resources for the plan, and of those that had used the plan, 94% indicated that they would continue to promote the plan, or one similar. CONCLUSIONS: The promotion of the asthma action plan in Canterbury had a major impact on health professionals. The community-wide promotion might have had a greater impact on people with asthma had television advertising been used. The pilot project provided useful feedback for the Asthma Foundation in their preparation for the national launch.

Infectious agents in respiratory disease of housed, fattening lambs in Northern Ireland.

A two-year longitudinal, microbiological and pathological survey of respiratory disease in lambs housed for fattening at three-and-a-half to four months of age was undertaken. In the first year samples of nasal mucus and blood were taken from lambs each week for the first nine weeks after entry to a fattening unit and each week one lamb was examined post mortem. In the second year two additional fattening units were included in the survey, when samples of blood and nasal mucus were taken from lambs twice weekly for three weeks after entry and two lambs from each unit were examined post mortem eight to 11 days after entry to the unit. In both years the lambs had a nasal discharge and were coughing. Mycoplasma ovipneumoniae and Pasteurella haemolytica were the organisms most consistently isolated from the lungs, trachea and nasal mucus. Mycoplasma arginini and parainfluenza-3 virus were also isolated. Post mortem examination lesions of atypical, pasteurella-type and parasitic pneumonias were seen. In the second year an abattoir survey of pneumonia lesions was undertaken. Areas of pulmonary consolidation were seen in 27.5 per cent, bands of consolidation in 47.5 per cent and muellerius-type lesions in 28 per cent of the lungs examined. No significant correlation was found between the slaughter weights of the lambs and the extent of the lung lesions at slaughter.

Pathological changes in the pericardium and meninges of cattle associated with Clostridium chauvoei.

Twenty-nine cases of Clostridium chauvoei infection in cattle were investigated over a two-year period. Fourteen had lesions of myositis only, eight had lesions of both myositis and fibrinous pericarditis, six had lesions of fibrinous pericarditis only and one had lesions of purulent meningitis only. Cl chauvoei was identified in all the lesions using the fluorescent antibody technique.
