Effective monitoring as a basis for adaptive management: a case history of mountain pine beetle in Greater Yellowstone Ecosystem whitebark pine

iForest - Biogeosciences and Forestry (2009)

Logan Ja William W. Macfarlane Louisa Willcox

With reference to massive outbreaks of a variety of bark beetles occurring across the forests of western North America, it is stressed that an accurate assessment of the extent of the problem is the first step toward formulating effective adaptive management strategies. This assessment will only be possible through a coordinated effort that combines all available technologies, that is an approach that builds on satellite image analysis, aerial survey from fixed-wing aircraft, and on the ground observation and measurement.

Does a chest x-ray alter the management of new patients attending a geriatric day hospital?

PubMed (1997)

Logan Ja R. Vallance Williams Bo Hyacinth Paul

Studies have suggested that routine chest x-ray is never indicated but all new attenders at our day hospitals have a chest x-ray carried out. Our aim was to determine if this investigation altered the clinical management of patients and to try to select those patients in whom a chest x-ray is indicated.A prospective study was carried out over a 7 month period from February to September 1995. All new patients had cardiorespiratory symptoms/signs documented and a management plan made. A chest x-ray was then carried out and change in management as a result of the x-ray report noted.Knightswood and Drumchapel Geriatric Day Hospitals, West Glasgow University NHS Trust.All new Day Hospital attenders.Of 207 new Day Hospital attenders, 53 had no clinical indication for a chest x-ray and although 70% had an abnormal film in no case was patient management changed as a result of this. A chest x-ray was indicated in 154 patients and of these 114 (74%) had an abnormal film with a resultant change in management in 23 patients (this comprised either a change in drug treatment or a further investigation.) Of those whose management was changed as a result of the x-ray report 61% had respiratory symptoms.We would recommend that chest x-ray should be performed in those patients who have a clear clinical indication and that the diagnostic yield is highest in the presence of respiratory symptoms or signs.

Bundling services saves everybody time.

From a practical viewpoint, the close relationships among utilization review, quality assurance/improvement, infection control, discharge planning, social services, and medical records makes it impossible to separate them. Case management combines these traditionally isolated hospital functions into one department in order to perform many related functions simultaneously. It provides a much more effective and efficient method than can be accomplished by the traditional institutional approach.
