While it is clear that the physician respondents practicing in a staff-model HMO in our study were significantly more likely to breach confidentiality in cases of patient-initiated health insurance fraud, the reasons for their decisions are not clear. We presented 2 possible hypotheses for the differences between physicians in staff-model HMOs and physicians in other practices; Salom presents an alternative hypothesis. It is clear that further work will be required to determine the reasons for differences among physicians in different practices.
