An Electronic Medical Record Pocket Guide for Incoming Internal Medicine Interns: Perceptions and Impact on Patient Information Gathering.

OBJECTIVES: The transition from medical student to intern is associated with a significant increase in workloads and responsibilities. This includes using the electronic medical record (EMR), which can lead to challenges in information gathering and patient care; however, no formal residency interventions exist in the use of an EMR for information gathering, with most EMR training occurring in the clinical setting. The present study aimed to improve information gathering on patient care and enhance the confidence of Internal Medicine interns in information gathering. METHODS: We performed a pre- and postprospective study in July 2021. All of the Internal Medicine interns at our community hospital were included. A pre- and postassessment to evaluate interns' confidence was distributed to participants during orientation week and at the end of the inpatient Internal Medicine rotation. A pre- and postconfidence assessment was collected at the beginning and end, respectively, of each intern's inpatient Internal Medicine rotation. RESULTS: Seventeen (85%) interns completed both the preassessment and postassessment. Use of an EMR guide led to a significant increase in completeness of patient information gathering (preassessment: 73.2% ± 18.4% vs post-EMR guide: 94.7% ± 7.4%, P < 0.001) and in intern confidence (P = 0.001). CONCLUSIONS: The use of an EMR guide was well received among Internal Medicine interns and led to increased completeness in patient information gathering. Residency programs may benefit from developing an EMR guide to improving the transition of interns during residency.

Distinct physiological and developmental properties of hippocampal CA2 subfield revealed by using anti-Purkinje cell protein 4 (PCP4) immunostaining.

The hippocampal CA2 subfield was initially identified by Lorente de Nó as an anatomically distinct region based on its cytoarchitectural features. Although there is an enormous body of literature on other hippocampal subfields (CA1 and CA3), relatively little is known about the physiological and developmental properties of CA2. Here we report identification of the CA2 region in the mouse by immunostaining with a Purkinje cell protein 4 (PCP4) antibody, which effectively delineates CA3/CA2 and CA2/CA1 borders and agrees well with previous cytoarchitectural definitions of CA2. The PCP4 immunostaining-delineated CA2 neurons have distinguishable differences in cell morphology, physiology, and synaptic circuit connections compared with distal CA3 and proximal CA1 regions. The average somatic sizes of excitatory cells differ across CA1-3, with the smallest to largest somatic size being CA1
