Impact of increased calls to rapid response systems on unplanned ICU admission.

BACKGROUND: Whether hospital bed number and rapid response system (RRS) call rate is associated with the clinical outcomes of patients who have RRS activations is unknown. We test a hypothesis that hospital volume and RRS call rates are associated with the clinical outcomes of patients with RRSs. METHODS: This is a retrospective chart analysis of an existing dataset associated with In-Hospital Emergency Registry in Japan. In the present study, 4818 patients in 24 hospitals from April 2014 to March 2018 were analyzed. Primary outcome variable was an unplanned intensive care unit (ICU) admission after RRS activation. RESULTS: In the primary analysis of the study using a multivariate analysis adjusting potential confounding factors, higher RRS call rate was significantly associated with decreased unplanned ICU admissions (P < 0.0001, Odds ratio [OR] 0.95, 95% confidence interval [CI] 0.92-0.98), but there was no significant association of hospital volume with unplanned ICU admissions (P = 0.44). In the secondary analysis of the study, there was a non-significant trend of increased cardiac arrest on arrival at the location of the RRS provider at large-volume hospitals (P = 0.084, OR 1.16, 95% CI 0.98-1.38). Large-volume hospitals had a significantly higher 1-month mortality rate (P = 0.0040, OR 1.10, 95% CI 1.03-1.18). CONCLUSION: Hospitals with increased RRS call rates had significantly decreased unplanned ICU admission in patients who had RRS activations. Patients who had RRS activations at large-volume hospitals had an increased 1-month mortality rate.

Hemostatic Spray TC-325 (Hemospray®) and Unexpected Esophageal Entrapment of Gastroscope With Airway Management Considerations: A Case Report.

Bleeding from the upper gastrointestinal tract is responsible for approximately 2% of all hospital admissions annually, with an up to 17% mortality rate. Therapeutic endoscopic interventions are often indicated for establishing hemostasis. These interventions include but are not limited to thermal coagulation with cautery, mechanical methods using band ligation or hemostatic clips, and hemostatic spray. Anesthesia providers are frequently involved in providing sedation for those endoscopic procedures. In 2018, the United States Food and Drug Administration approved a hemostatic spray, Hemospray® TC-325 (Cook Medical, Winston- Salem, NC, USA) for controlling nonvariceal upper gastrointestinal bleeding. The inorganic, mineral-based powder forms a mechanical tamponade by absorbing water and attracting clotting factors to the bleeding site. Adverse events associated with using the product are reported as rare but have included perforation and difficulty in removing the gastroscope. This case presents unexpected entrapment of the gastroscope in a patient's esophagus after the bleeding site was treated with Hemospray. Potential difficulties with airway management strategies are discussed.
