Background: The COVID-19 pandemic has resulted in the implementation of rapidly changing protocols and guidelines related to the indications and perioperative precautions and protocols for tracheostomy. The purpose of this study was to evaluate current guidelines for tracheostomy during the COVID-19 pandemic to provide a framework for health systems to prepare as the science evolves over the upcoming months and years.Methods: Literature review was performed. Articles reporting clinical practice guidelines for tracheostomy in the context of COVID-19 were included.Results: A total of 13 tracheotomy guidelines were identified. Two were available via PubMed, five in society or organization websites, and six identified via health system websites or other sources. Five were from Otolaryngology-Head and Neck Surgery specialties, six from Anesthesiology and one from Pulmonary/Critical Care. All (100%) studies recommended postponing elective OR cases in COVID-19 positive patients, while seven recommended reducing team members to only essential staff and three recommended forming a designated tracheostomy team. Recommendations with supporting references are summarized in the article. Conclusions: Tracheostomy guidelines during the COVID-19 pandemic vary by physician groups and specialty, hospital systems, and supply-chain/resource availability. This summary is provided as a point-in-time current state of the guidelines for tracheotomy management in April 2020 and is expected to change in coming weeks and months as the COVID-19 pandemic, virus testing and antibody testing evolves.

IMPORTANCE Data regarding outcomes after major head and neck ablation and reconstruction in the growing geriatric population (specifically Ն80 years of age) are limited. Such information would be extremely valuable in preoperative discussions with elderly patients about their surgical risks and expected functional outcomes.OBJECTIVES To identify patient and surgical factors associated with 30-day postoperative complications, 90-day mortality, and 90-day functional decline; to explore whether an association exists between the type of reconstructive procedure and outcome; and to create a preoperative risk stratification system for these outcomes. DESIGN, SETTING, AND PARTICIPANTSThis retrospective, multi-institutional cohort study included patients 80 years or older undergoing pedicle or free-flap reconstruction after an ablative head and neck surgery from January 1, 2015, to December 31, 2017, at 17 academic centers. Data were analyzed from February 1 through April 20, 2019. MAIN OUTCOMES AND MEASURESThirty-day serious complication rate, 90-day mortality, and 90-day decline in functional status. Preoperative comorbidity and frailty were assessed using the American Society of Anesthesiologists classification, Adult Comorbidity Evaluation-27 score, and Modified Frailty Index. Multivariable clustered logistic regressions were performed. Conjunctive consolidation was used to create a risk stratification system. RESULTS Among 376 patients included in the analysis (253 [67.3%] men), 281 (74.7%) underwent free-flap reconstruction. The median age was 83 years (range, 80-98 years). A total of 193 patients (51.3%) had 30-day serious complications, 30 (8.0%) died within 90 days, and 36 of those not dependent at baseline declined to dependent status (11.0%). Type of flap (free vs pedicle, bone vs no bone) was not associated with these outcomes. Variables associated with worse outcomes were age of at least 85 years (odds ratio [OR] for 90-day mortality, 1.19 [95% CI 1.14-1.26]), moderate or severe comorbidities (OR for 30-day complications, 1.80 [95% CI, 1.34-2.41]; OR for 90-day mortality, 3.33 [95% CI, 1.29-8.60]), body mass index (BMI) of less than 25 (OR for 30-day complications, 0.95 [95% CI, 0.91-0.99]), high frailty (OR for 30-day complications, 1.72 [95% CI, 1.10-2.67]), duration of surgery (OR for 90-day functional decline, 2.94 [95% CI, 1.81-4.79]), flap failure (OR for 90-day mortality, 3.56 [95% CI, 1.47-8.62]), additional operations (OR for 30-day complications, 5.40 [95% CI, 3.09-9.43]; OR for 90-day functional decline, 2.94 [95% CI, 1.81-4.79]), and surgery of the maxilla, oral cavity, or oropharynx (OR for 90-day functional decline, 2.51 [95% CI, 1.30-4.85]). Age, BMI, comorbidity, and frailty were consolidated into a novel 3-tier risk classification system.CONCLUSIONS AND RELEVANCE Important demographic, clinical, and surgical characteristics were found to be associated with postoperative complications, mortality, and functional decline in patients 80 years or older undergoing major head and neck surgery.

IMPORTANCE Identifying high-risk patients in the preoperative period can allow physicians to optimize nutritional status early for better outcomes after head and neck cancer resections. OBJECTIVE To develop a model to predict preoperatively the need for gastrostomy tube (G-tube) placement in patients undergoing surgery of the upper aerodigestive tract. DESIGN, SETTING, AND PARTICIPANTS This retrospective medical record review included all adult patients diagnosed with head and neck cancers who underwent tumor resection from 2007 through 2012 at Wake Forest Baptist Health, a level 1 tertiary care center. Records were screened for patient demographics, tumor characteristics, surgical treatment type, and postoperative placement of G-tube. A total of 743 patients underwent resection of head and neck tumors. Of these, 203 were excluded for prior G-tube placement, prior head and neck resection, G-tube placement for chemoradiotherapy, and resection for solely nodal disease, leaving 540 patients for analysis. MAIN OUTCOMES AND MEASURES Placement of postoperative G-tube. RESULTS Of the 540 included patients, 23% required G-tube placement. The following variables were significant and independent predictors of G-tube placement: preoperative irradiation (odds ratio [OR], 4.1; 95% CI, 2.4–6.9; P < .001), supracricoid laryngectomy (OR, 26.0; 95% CI, 4.9–142.9; P < .001), tracheostomy tube placement (OR, 2.6; 95% CI, 1.5–4.4; P < .001), clinical node stage N0 vs N2 (OR, 2.4; 95% CI, 1.4–4.2; P = .01), clinical node stage N1 vs N2 (OR, 1.6; 95% CI, 0.8–3.3; P = .01), preoperative weight loss (OR, 2.0; 95% CI, 1.2–3.2; P = .004), dysphagia (OR, 2.0; 95% CI, 1.2–3.2; P = .005), reconstruction type (OR, 1.9; 95% CI, 1.1–2.9; P = .02), and tumor stage (OR, 1.8; 95% CI, 1.1–2.9; P = .03). A predictive model was developed based on these variables. In the validation analysis, we found that the average predicted score for patients who received G-tubes was statistically different than the score for the patients who did not receive G-tubes (P = .01). CONCLUSIONS AND RELEVANCE We present a validated and comprehensive model for preoperatively predicting the need for G-tube placement in patients undergoing surgery of the upper aerodigestive tract. Early enteral access in high-risk patients may prevent complications in postoperative healing and improve overall outcomes, including quality of life.
