69 Assessing the fidelity of implementing complex interventions addresses type III error and provides evidence of variability in implementation of interventions, which could also contribute to limited effectiveness.
Furthermore, MPs may play a crucial role in implementation of interventions for this vulnerable population and therefore their attitudes towards exercise prescription, and delivery, provides useful formative research in the field.
The quality improvement (QI) literature points to the importance of contextual factors in implementation of interventions [ 49, 50], and suggests that contextual factors at the microsystem level (rather than organisational factors) may have a more direct influence on QI success [ 51].
HLM, SI, BMR, PB, VG, SM, and JFB were involved in implementation of the intervention, designing and supervising the data collection and analysis, and interpretation of the findings.
A sub-sample of the Practice Nurses, GPs and patients involved in the study will be asked to participate in a semi-structured interview at the conclusion of the study to understand factors influencing variation in implementation of the intervention.
All primary care members involved in the study will be asked to participate in a semi-structured interview at the conclusion of the study to understand factors influencing variation in implementation of the intervention.
They will be able to report on any highlights, any problems or barriers in implementation of the interventions, and to make recommendations on the improvement of intervention implementation.
Preintervention, baseline data were collected in 2008 and again an average of 2 years later, between 3 and 6 months postintervention (due to difficulties and delays in implementation of the interventions, only seven sites were available for postintervention survey).
Comments: This paper is integral in future implementation of intervention programs designed to retain health forces in rural areas.
These studies can also indicate the level of challenge to be faced in the implementation of intervention strategies [ 8].
