Purpose: Compare the use of medical therapy alone (MTA) with surgical therapy (ST) for the empiric treatment of peritonsillar abscess (PTA).

Materials And Methods: A consecutive cohort of patients treated for PTA at our institution from May 2013 to February 2019 was analyzed. Demographics, disease characteristics, management strategies, and treatment outcomes were compared between treatment groups. Primary outcomes included treatment failure, defined as the need for follow-up surgical intervention, and complications within 2-weeks of empiric treatment.

Results: 306 patients (72.7%) received MTA while 115 (27.3%) underwent ST. There was no significant difference in the rate of treatment failure between the MTA (7.2%) and ST (6.1%) groups (p = 0.879). Complications were rare in both groups (1.6% with MTA versus 0.9% with ST; p = 0.898). Dysphagia (p = 0.011), trismus (p = 0.045), larger abscesses (p < 0.001), and hospital admission (p < 0.001) were more common in the ST group. Corticosteroid prescriptions were a common component of MTA (53.3%) and less often used with ST (33.9%; p = 0.001). After adjusting for abscess size, there remained no significant difference in the rate of treatment failure between groups. Univariate analyses demonstrated no significant independent predictors of treatment failure including age, sex, race, tonsillitis history, smoking history, presenting signs and symptoms, abscess size, hospital admission, and corticosteroid prescriptions.

Conclusions: MTA may be a safe and effective alternative to surgical drainage for the empiric treatment of PTA, warranting larger-scale prospective analyses. Abscess size did not appear to influence treatment failure; however, careful patient selection is likely to optimize treatment outcomes.

Going vertical: triage flags improve extraction times for priority patients.

J Am Coll Emerg Physicians Open 2020 Dec 21;1(6):1185-1193. Epub 2020 Aug 21.

Objective: The number of mass casualty incidents (MCIs) has been steadily increasing. High-priority MCI patient outcomes are highly dependent on rapid identification, treatment, and transport. Although there are several methods used to mark patients for rapid extraction, most current methods utilize low-profile tags, with no gold standard. This study examines if the use of a vertical cue, a triage flag, to identify high priority MCI patients results in faster extraction times than those with a wrist triage tag alone.

Methods: A prospective randomized crossover study was conducted with medical students trained in basic disaster life support, who completed 2 extraction simulations. Two fields were each arranged with 32 randomly placed, pretriaged manikins (10 red, 17 yellow, 5 black). The manikins were marked with either triage tags alone or with triage tags and flags. The total time elapsed for participants to report all high-priority manikin triage tag numbers was recorded.

Results: Eighty-two participants completed both simulations. The average completion time for the "tags-only" simulation was 94.5 seconds (±16.4 seconds) compared to 70.7 seconds (±13.2 seconds) for the flags and tags simulation. This corresponds to an average decrease of 23.8 seconds ( < 0.0001), or a 25.2% reduction in time.

Conclusion: Using a vertical cue decreased the time required to identify high-priority patients. This suggests that a rapidly deployable and visually apparent triage marker may allow faster identification and extraction of patients across a field of victims with varying injury severities than a flat horizontal triage tag, thereby potentially improving patient outcomes.
