Preserving Patient Privacy During Computation over Shared Electronic Health Record Data.

Patient Electronic Health Records (EHRs) contain valuable clinical data that is useful for medical research and public health inquires. However, patient privacy regulation and improper resource sharing risks limit access to EHR medical data for research and public health purposes. In this paper, we introduce an end-to-end security solution that addresses both concerns and facilitates the sharing of patient EHR data over an unsecured third-party server using a leveled homomorphic encryption (LHE) scheme. Time testing for aggregating queries and linear computations was carried out using an HPE ProLiant DL580 Gen 10 server with an Intel Xeon Platinum 8280 Processor.

Effects of a Resident-Led Subject Exam Review on Mean Scores of Internal Medicine Subject Exam: a Case-control Study.

The National Board of Medical Examiners (NBME) offers Subject Examinations (SE) for students completing the Internal Medicine (IM) clerkship. There is a paucity of literature in regard to the efficacy of review methods prior to rendering said examination. Our medical center's residents conducted a structured review session in preparation for SE administration. The mean SE scores prior to and after the initiation of the resident-led review session were compared. There was no statistically significant association found between the mean NBME scores in the experimental or control groups. We propose that alternative methods be further assessed for efficacy.
