Another limitation to micro-costing is the substantial burden it places on the research team and intervention personnel.
The intervention personnel chose workshop topics based on their observations of teachers in the field and teachers' requests for information related to children's physical activity.
Our cost estimates exclude supplies, office space for intervention personnel, and storage space for records because we believe this type of intervention would normally be implemented using existing staff and facilities.
To minimize risks associated with increasing physical activity, intervention personnel will screen participants at each encounter point to assess symptoms that would increase the risk of physical activity and to report concerns as appropriate.
During the first year of the study, intervention personnel created a password-protected website as a resource for a sharing and networking community, but they discontinued use of the website in the second year due to infrequent teacher participation.
The reason for this selection was that in the reference group the participants received no intervention, and in the combined exercise and diet groups, two members of the intervention-group personnel evaluated the participant's success in each intervention separately.
Implementation of intervention Teachers and nurses logs : During the intervention, school personnel and immunisation nurses will complete study logs.
By far the largest cost component for the MI intervention was personnel time, the primary personnel being nurses.
In addition, the intervention-group personnel met the participants regularly and interviewed and in this way, they ensured that the subjective evaluation was reliable.
Data on each model of palliative care were extracted using an electronic proforma according to a recently published disease management taxonomy which considered: patient population, intervention recipient; intervention content, delivery personnel, method of communication, intensity and complexity, environment and clinical outcomes [ 17].
