Example: delayed diagnosis of sepsis & delayed recognition of a postoperative complication 59 year old female underwent TAH POD #3 AKI, urinary retention with new abdominal distension and pain POD #4 AKI worse, significant abdominal pain narcotics stopped. Episode of PAF (130 s) POD #5 hypotensive (70/45) with diaphoresis and nausea RRT called but no blood pressure on their arrival Code called with > 1hr of resuscitation efforts On autopsy, abdomen filled with pus and a knick in the small bowel. 2013 MFMER slide-20
Labs: Hb: 7.1, Leukocytes: 2.3 Creat (9/29): 3 (2-month baseline): 1.6 Case Example 44 hours 27 hours Clear change in physiologic state Met RRT Criteria RRT called 55-year-old male with CLL with MUD peripheral blood stem cell transplant 7/10 (2 months before). Dismissed 9/14 2013 MFMER slide-21

System Architecture Requirements: Tiered rescue model with time limited escalation of expertise with demonstrated clinical response Bedside evaluations Increased provider vigilance RRT to be called when their specific expertise is needed Promotes teamwork and communication Makes the deterioration and results of interventions visibly obvious to bedside providers Allows all types of students, residents and fellows to learn Allows patient and family preferences to be incorporated into rescue response Makes practice constraints evident Leverages technology at the point of care (bedside) Research supported by CSHCD 2013 MFMER slide-24
Tiered, time-limited escalation of expertise at the bedside RN clinical verification of vital signs Validation Evaluate/treat/resolve or silence/snooze Max 2-6 hours Tier 1 First responder to bedside & notifies senior member of team Evaluate/treat/resolve or silence/snooze Max 2-3 hours Tier 2 Tier 3? RRT Second responder to bedside for eval of clinical condition, differential, goals of care, and plan for reassessment Concept derived from 7 RN focus groups & discussions with MERS, Sepsis MTR, CC- IMP & HIM quality committee including their practice leadership. MANY details to sort through as portion of Phase 2 BPR Charter. The practice must design the process and policies. 2013 MFMER slide-25

How about a good death? Example: palliation failure 82 year old male with severe COPD and pancreatic cancer was hospitalized for bowel obstruction. Postoperative delirium Postoperative respiratory failure Pain meds held Per nursing notes, patient routinely called out in pain and family members consistently asked that he be kept comfortable. His average pain score was 8/10 in the 24 hours preceding death. Joshua Bright: A Good Death 2 days later, patient was made comfort care only and died within hours. 2013 MFMER slide-27
