    Patient-Centered Outcome Spectrum: An Evidence-based Framework to Aid in Shared Decision-making.
    Ann Surg 2017 Sep 15. Epub 2017 Sep 15.
    University of Wisconsin School of Medicine and Public Health, Department of Surgery, Madison, WI.
    Objective: Our objective was to develop an alternate construct for reporting anticipated outcomes after emergency general surgery (EGS) that presents risk in terms of a composite measure.

    Background: Currently available prediction tools generate risk outputs for discrete as opposed to composite measures of postoperative outcomes. A construct to synthesize multiple discrete estimates into a global understanding of a patient's likely postoperative health status is lacking and could augment shared decision-making conversations.

Ross School of Business, University of Michigan, Ann Arbor, MI.
    : In response to technological advances and growing dispersion of surgical practice around the globe, social media platforms have emerged in recent years as channels for surgeons to share experiences, ask questions, and learn from one another. To better understand surgeons' engagement with these platforms, we analyzed data from a closed-membership Facebook group for robotic surgeons. Our analysis revealed that surgeons posted more frequently on midweek days, and further that text posts received significantly more comments, and significantly fewer "likes," than posts containing links, photos, or videos.
