Prehospital, post-ROSC blood pressure and associated neurologic outcome.

OBJECTIVE: To investigate the relationship between hypotension and neurologic outcome in adults with return of spontaneous circulation after out-of-hospital cardiac arrest. METHODS: Blood pressure and medication data were extracted from adult patients who had ROSC after OHCA in Alameda County and matched with neurologic outcome using the CARES database from January 1, 2018 through July 1, 2019. We used univariate logistic regression with p ≤ 0.2 followed by multivariate logistic regression and reported an odds ratio with 95% confidence intervals. RESULTS: Among the 781 adult patients who had ROSC after OHCA, 107 (13.7%) were noted to be hypotensive and 61 (57% of the hypotensive group) received vasopressors. Patients with a final prehospital blood pressure recording of <90 mmHg were more likely to have a poor neurologic outcome (adjusted odds ratio 2.13, adj p = 0.048). About twice as many patients who were not hypotensive had a good neurologic outcome compared to hypotensive patients who had a good neurologic outcome (23% to 10.3%). Additionally, patients who were hypotensive and did not receive vasopressors had a similar neurologic outcome compared to patients who did receive vasopressors. CONCLUSION: Prehospital post-ROSC hypotension was associated with worse neurologic outcome and giving hypotensive patients vasopressors may not improve neurologic outcome in the prehospital setting.

Hypoglycemia Patients and Transport by EMS in Alameda County, 2013-15.

OBJECTIVE: To estimate the rate, characteristics, and dispositions of hypoglycemia events among persons who received care from Alameda County, California, Emergency Medical Services (EMS). METHODS: This study was based on data for 601,077 Alameda County EMS encounters during 2013-15. Subjects were defined as having hypoglycemia if EMS personnel recorded a primary impression of hypoglycemia or low blood glucose (<60 mg/dl or "unspecified low"). The outcome of interest was patient transport or non-transport to an emergency department or other care setting; we excluded 33,177 (6%) encounters which lacked clear disposition outcomes. RESULTS: Among 567,900 eligible encounters, 8,332 (1.47%) were attributed to hypoglycemia, of which 1,125 (13.5%) were not transported. Non-transport was more likely among males, adult patients age <60, initial blood glucose >60 mg/dl or EMS arrival time 18:00-6:00. CONCLUSIONS: Without an understanding of EMS encounters and non-transport rates, surveillance based solely on emergency department and hospital data will significantly underestimate rates of severe hypoglycemia. Additionally, given that hypoglycemia is often safely and effectively treated by non-physicians, EMS protocols should provide guidance for non-transport of hypoglycemic patients whose blood glucose levels have normalized.

Hospice and Comfort Care Patient Utilization of Emergency Medical Services.

Introduction: Emergency medical services (EMS) were designed to prevent death and disability. When hospice patients call 9-1-1, it can create challenging scenarios for EMS providers, patients, and families. The objective of this investigation is to understand the characteristics of hospice and comfort care patient EMS utilization in Alameda County, California. Methods: This is a 15-month (7/1/2019-10/1/2020) retrospective observational study in Alameda County using electronic patient care reports (PCRs). The search terms "hospice" and "comfort measures only" were applied to PCR narratives. Results: Of the 237,493 EMS provider response calls, 534 (0.2%) were for hospice and comfort care patients. One hundred seventy-four (32.6%) calls were from skilled nursing facilities versus 343 (64.2%) from private residences. Among the most common primary impressions were respiratory complaints (96; 18.0%), altered mental status (96; 18.0%), weakness (58; 10.9%), and cardiac arrest (45; 8.4%). The most common interventions included blood glucose (244; 45.7%), electrocardiogram (181; 33.9%), and intravenous placement (170; 31.8%). Of note, eight (1.5%) patients received cardiopulmonary resuscitation, and an additional eight (1.5%) patients were intubated endotracheally or received a supraglottic airway device for intubation. Sixty-eight (12.7%) patients received medications, the most common of which were fentanyl (17; 3.2%) and albuterol (16; 3.0%). Of note, five (0.9%) patients received naloxone. Ultimately, 468 (87.6%) patients were transported by EMS. Of the 33 (6.1%) patients who died on the scene, three received resuscitation attempts. Conclusion: Although EMS providers encounter hospice and comfort care patients infrequently, awareness of hospice services and comprehensive end-of-life care communication skills with patients and family should be an important part of EMS.
