3. Retrieve. The PHO system documents the consenting process and process
the data collection request, using the approving physician’s credentials to
automatically retrieve records in batch on behalf of all approved patients
from all hospital physicians who approved access.
4. Access. The patient checks the status of submitted requests. He will find
some requests get approved, some pending, while others get rejected with
rejection reasons stated in the commenting fields. The retrieved records
may be completely reorganized by the PHO system to improve patient selfeducation
and ease of data interpretations.
5. Annotate. The patient reviews his/her personal health charts, event logs,
and medical treatment transcripts about themselves. He/She adds
comments to the health log events for his/her own health record keeping.
6. Share. The patients, after filtering private information, may choose to
share some information online with others, including his/her peers and
physicians, to promote health self-education in his community.
The benefits of this physician-mediated patient EMR review paradigm are
potentially huge. The patients can quickly gain access to their EMR and integrate
accessed records into their PHR immediately. The patients can also discover
potential inaccuracies (such as personal information or current medications),
which allows the hospitals to correct. The hospitals don’t need to worry about
developing increasingly complex EMR system to yet another audience—individual
