  • What is the optimal number of evals for residents and attending to fill out? Would having fewer result in higher quality? How often do residents and attendings look at their medhub evals? Does anyone find them useful? If they are not useful, lets stop doing them, or tweak it (to be less frequent)
  • Having anesthesia residents/attendings assigned some complex cases 1 month in advance and then have them do the pre-anesthetic eval and interim optimization for that patient. Perhaps even a post-op follow-up call or visit.
  • Low-flow anesthesia real-time decision support built into EPIC (or laminated card reminder placed on workstations). See Baby Miller pg. 877.
  • Is there anyway to educate providers on how (or if) anesthetic management decisions affect the bill the patient sees?
  • Recycling and waste sortage in the OR. Also, getting rid of ProVu!

Good

Very Ambitious, But Still Cool

  • NIBP monitoring from head/neck
  • Can you modulate the strength of the Bohr effect?
  • Better way of determining fluid status
  • Novel reversal agents (e.g. volatile anesthetics, propofol, precedex)
  • Permanently inhibit a nerve to prevent phantom pain after amputation.
  • Reversible chemical/optical/electromagnetic knockdown/inhibition/interference of pain nuclei/DRG/dorsal column/STT activity in rodents/primates. https://onlinelibrary.wiley.com/doi/pdf/10.1002/ejp.1136
  • Fentanyl patch instead of remifentanil infusion? What other anesthetics could you deliver via patch? Could you do a patch induction for Peds? There is no remifentanil or sufentanil patch.
  • What is the MoA of APAP?
  • Transfusion thresholds

Already Done

Not Super Exciting/Impactful

  • Which findings on the preop note predict pressors use during the case?
  • EPIC timeline builder
  • Does setting realistic pain expectations in pre-op decrease self-reported pain scores in PACU?
  • Ultrasound vs blind A-line first attempt success rate and complications?
  • How do epidurals affect gastric emptying?
