A study to evaluate the efficacy of a secure webbased patient portal
  
Setting: Primary Care
 | 
- N= 163 patients;
- 84 Patient Gateway users vs. 79 non-users
- Sending PCP a clinical message providing patient-reported information vs. no clinical message
 | 
- A lower % of PG users’ drug regimen was reported to be correct than those of PG nonusers (54% vs 61%)
- Notifying physicians of medication discrepancies via email had no effect
 | 
- Med lists in EHRs were frequently inaccurate
- Patient access to PG was not associated with more accurate medication lists in EHR
- Clinical messages to physicians containing patient-provided medication updates did not result in physician updating the med list in EHR
