Future Research
In the next phase of our study we will test the model’s factors quantitatively on a random sample of physicians and go through the same steps with a patient/consumer sample. Ultimately, we will use a modified model to design interventions to assist with the implementation of preventive services guidelines.
Conclusions
Our findings are of importance for those implementing preventive care guidelines. The focus group participants were clearly less happy with guidelines that were equivocal, and were less likely to follow them. Patient factors and the physician-patient relationship appear to be important in such cases. Although patient-oriented decision aids could help physicians in these situations, it is clearly more difficult to develop aids to guide patients in settings when the evidence is unclear, because the information required is more complex. The family physicians’ perceptions of the effectiveness of a particular screening test was very important, perhaps more important to the participants than the scientific evidence behind a guideline. Although personal experience is a weak and unscientific level of evidence subject to many biases, it is likely an important influence on cancer screening decision making in primary care, particularly when the evidence is uncertain. Future education efforts directed at primary care providers should address the influence of personal experience as well as the failure to attend to the level of evidence behind recommendations.
