Harnessing Reliable Evidence in the Post-COVID Era: A Practice Guide to Navigating the Ocean of Medical Literature

The reliability and relevance of medical literature are significant concerns in the post-COVID-19 era, where misinformation and disinformation are serious threats. This practice guide provides an overview of practical strategies to appraise the reliability of research publications critically. These strategies include critically appraising the effectiveness and constraints of various approaches to disseminating medical information, choosing appropriate medical literature resources, navigating library databases, screening the literature from the search, and screening individual publications. We also discuss the importance of considering study limitations and the relevance of the results in research or use in the medical arena. In-depth, critical appraisal of medical or clinical research evidence requires expertise, insight into research methodologies, and a grasp of issues in each field. By harnessing the wealth of reliable and relevant information available in medical literature through the above steps, we can alleviate potentially misleading information and stay at the forefront of our respective fields.

Preoperative Snack Prescription: A Single-Centre Experience in Optimising Preoperative Fasting Time and Enhancing Guideline Adherence

Objectives Preoperative fasting plays a pivotal role in adequately preparing patients for anaesthesia and surgical procedures. However, it is imperative to consider not only the medical aspects but also patients' overall comfort, as this can significantly contribute to improved surgical outcome. The primary objective of this quality improvement project (QIP) is to provide healthcare professionals, including anaesthetists, surgeons, nurses, and stakeholders with information regarding insights required to embrace the concept of preoperative snack prescription as a strategy for enhancing patient-centred care. Methods This QIP was conducted in the vascular surgery department of a district general hospital in Wales, United Kingdom. A prospective analysis was conducted in two cycles, i.e., the pre-intervention group (PrIG) and post-intervention group (PoIG), with preoperative snacks such as biscuits, chips, or cakes, being prescribed to the PoIG. A total of 40 patients who met the inclusion criteria were enrolled in this study, with 20 patients participating in each cycle. The timing of preoperative meals, i.e., the closest preoperative breakfast, lunch, or dinner, preoperative snacks (for the PoIG), anaesthesia commencement, and surgical commencement were collected. Data analysis was performed using IBM SPSS Statistics for Windows, Version 26.0 (Released 2019; IBM Corp., Armonk, New York, United States), in conjunction with Microsoft Excel (Microsoft Corporation, Redmond, Washington, United States). Results In our QIP, the PrIG and PoIG comprised 40% (8 out of 20) and 35% (7 out of 20) female patients, respectively, with mean ages of 74 years (range, 61-86 years) and 61.3 years (range, 36-81 years). Within the PrIG, the mean duration from the preoperative meal to anaesthesia and surgery commencement was 17.8 hours (range, 14.6-22.5 hours) and 18.5 hours (range, 16.0-23.3 hours), respectively. In the PoIG, following the initiation of preoperative snack prescription, the mean time intervals between preoperative snack prescription and anaesthesia and surgery commencement were 10.9 hours (range, 6.5-16.0 hours) and 12.0 hours (range, 7.5-16.5 hours), respectively. Conclusions In summary, our QIP has successfully integrated preoperative snack prescription into the local hospital's preoperative care policy, prioritising the balance between patient safety and comfort. Based on our single-centre experience, we observed a significant reduction in the time interval between preoperative fasting and the initiation of anaesthesia, decreasing from 18.3 hours to 10.9 hours post-implementation of preoperative snacks. This QIP holds relevance for healthcare professionals as it underscores the benefits of shorter fasting periods, which contribute to heightened patient satisfaction and comfort.

Longer Times to Delivery of Otolaryngology Care for Patients With Limited English Proficiency

OBJECTIVE

Limited English proficiency (LEP) is known to contribute to poorer health outcomes and delays in management. However, to our knowledge, no other studies have explored the impact of LEP on delays to care within otolaryngology. This study aims to investigate the relationship between LEP and the time to delivery of otolaryngology care.

METHODS

We retrospectively reviewed 1125 electronic referrals to an otolaryngologist from primary care providers at 2 health centers in the greater Boston area, between January 2015 and December 2019. Multivariable logistic regression analyses were conducted to determine if patient LEP status (preferred language non-English and language interpreter use) has an impact on total time to appointment (TTTA).

RESULTS

Patients with non-English preferred languages were 2.6 times more likely to experience extended TTTA (odds ratio [OR] = 2.61, 95% confidence interval [CI] = 1.99-3.42, p < .001) relative to English-speaking patients. Patients who required interpreter use were 2.4 times more likely to experience extended TTTA (OR = 2.42, 95% CI = 1.84-3.18, p < .001) relative to patients who did not require an interpreter. There was no difference in age, sex, insurance type, education level, or marital status. TTTA did not vary by diagnosis category (p = .09).

DISCUSSION

LEP is an important factor that influences the time to appointment in our cohort. Notably, the impact of LEP on appointment wait times was independent of diagnosis.

IMPLICATIONS FOR PRACTICE

Clinicians should recognize LEP as a factor that can impact the overall delivery of care in otolaryngology. Specifically, mechanisms to streamline care for LEP patients should be considered.

Interdisciplinary Simulation Training Reduces Restraint Use in the Emergency Department: A Pilot Study

Introduction Safe and effective management of agitated patients poses multiple challenges for healthcare professionals. Patients placed in restraints because of agitated behavior are at a higher risk of complications, including death. This intervention was designed to provide emergency department staff a framework for de-escalation, improve teamwork, and reduce the use of violent physical restraints. Methods Emergency medicine nurses, patient support associates, and protective services officers underwent a 90-minute educational intervention in 2017. A 30-minute lecture focusing on communication and early use of medication for agitation was followed by a simulation using standardized participants, then a structured debriefing. A standardized return-on-learning tool determined participants' reactions to and application of the educational intervention. Additionally, data was collected and reported as a ratio of number of restraints applied each month compared to total emergency department visits that month. Data were analyzed comparing the six months before the education and the subsequent six months after the education. Results A pilot group of 30 emergency department staff members completed the educational intervention. The intervention contributed to the overall decrease in restraint use in the department. Most participants (86%) felt more confident in their ability to manage agitated patients. Conclusion An interdisciplinary simulation-enhanced educational intervention successfully reduced use of restraints in the emergency department and improved staff attitudes toward de-escalation techniques for agitated patients.

An Approach to Leadership Development and Patient Safety and Quality Improvement Education in the Context of Professional Identity Formation in Pre-Clinical Medical Students

Objectives

Leadership and patient safety and quality improvement (PSQI) are recognized as essential parts of a physician's role and identity, which are important for residency training. Providing adequate opportunities for undergraduate medical students to learn skills related to these areas, and their importance, is challenging.

Methods

The Western University Professional Identity Course (WUPIC) was introduced to develop leadership and PSQI skills in second-year medical students while also aiming to instill these topics into their identities. The experiential learning portion was a series of student-led and physician-mentored PSQI projects in clinical settings that synthesized leadership and PSQI principles. Course evaluation was done through pre/post-student surveys and physician mentor semi-structured interviews.

Results

A total of 108 of 188 medical students (57.4%), and 11 mentors (20.7%), participated in the course evaluation. Student surveys and mentor interviews illustrated improved student ability to work in teams, self-lead, and engage in systems-level thinking through the course. Students improved their PSQI knowledge and comfort levels while also appreciating its importance.

Conclusion

The findings from our study suggest that undergraduate medical students can be provided with an enriching leadership and PSQI experience through the implementation of faculty-mentored but student-led groups at the core of the curricular intervention. As students enter their clinical years, their first-hand PSQI experience will serve them well in increasing their capacity and confidence to take on leadership roles.

Objective Assessment of Aerosolization During Transnasal Endoscopy: A Systematic Review

OBJECTIVE

The goal of this systematic review is to assimilate the literature on objective assessment of particulate aerosolization during transnasal endoscopic procedures.

DATA SOURCES

PubMed and hand-searched articles.

REVIEW METHODS

The PubMed electronic database was searched using Medical Subject Headings and free-text search terms relating to aerosolization and transnasal endoscopic procedures from inception to November 16, 2020. References were hand-searched to identify additional publications for consideration. Inclusion in the systematic review required quantification of aerosol generation during clinic transnasal endoscopic procedures. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and flowchart were followed during the systematic review.

RESULTS

Eight of 900 studies met criteria for inclusion in the systematic review. Five studies tested nasal endoscopy with mixed findings on the risk of aerosol generation during this procedure. Two studies assessed flexible fiberoptic laryngoscopy and also reported mixed findings. Breathing, sneezing, speech, and spray anesthetic/decongestants were found to consistently increase aerosol generation above baseline. A number of studies tested new and general mitigation strategies and were found to be effective in decreasing aerosol generation.

CONCLUSIONS

The coronavirus disease 2019 pandemic has informed many considerations regarding patient and provider safety. It is valuable to understand the risk during outpatient otolaryngology procedures through the quantification of aerosolization. There are several effective methods to control aerosolization during these procedures. The findings of this systematic review will inform appropriate precautions to protect against spread of infectious agents by aerosolization.

Pediatric Tracheostomy-Related Complications: A Cross-sectional Analysis

OBJECTIVE

To determine the rate of tracheostomy-related complications in pediatric patients from nationally representative databases.

STUDY DESIGN

Cross-sectional analysis.

SETTING

2016 Kids' Inpatient Database and 2016 Nationwide Readmission Database.

METHODS

All pediatric tracheostomy procedures were included. Complication type, admission outcomes, and readmission rates were recorded with a logistic regression analysis to determine patient characteristics associated with complications.

RESULTS

An estimated 5309 tracheostomies were performed among pediatric patients in 2016, 8% (n = 432) of whom developed tracheostomy-related complications. This group was younger (4.7 vs 8.7 years, P < .001) and required longer hospital admissions (68.7 vs 33.2 days, P < .001) than children without tracheostomy-related complications. Mean costs ($459,324 vs $397,937, P < .001) and mean total charges ($1,573,964 vs $1,099,347, P < .001) were increased if a tracheostomy-related complication occurred. These events occurred more often in those with bronchopulmonary dysplasia (24% vs 12%, P < .001), heart disease (24% vs 12%, P = .001), gastroesophageal reflux disease (31% vs 19%, P < .001), short gestational age (24% vs 14%, P < .001), and subglottic stenosis (9.9% vs 5.4%, P = .001). The estimated 30-day readmission rate was 24% (SE, 1.7%) but did not increase after tracheostomy complications (27% vs 15%, P = .04). Tracheostomy-related complications were predicted by gastroesophageal reflux disease (odds ratio [OR], 1.50; 95% CI, 1.14-1.97; P = .004), younger age (OR, 1.12; 95% CI, 1.04-1.22; P = .002), and lengthier hospitalization (OR, 1.00; 95% CI, 1.00-1.01; P < .001) on multiple logistic regression analysis.

CONCLUSION

Tracheostomy-related complications occur in approximately 8% of pediatric patients and are higher in younger children or those with longer admission lengths. These data have implications for benchmarking standards of posttracheostomy complications across institutions.

Perioperative Outcomes After Tracheostomy Placement Among Complex Pediatric Patients

OBJECTIVES/HYPOTHESIS

To compare perioperative outcomes after pediatric tracheostomy placement based on patient complexity.

STUDY DESIGN

Retrospective case series.

METHODS

All patients that underwent tracheostomy placement at a tertiary children's hospital between 2015 and 2019 were followed. Children with a history of major cardiac surgery, sepsis, or total parental nutrition (TPN) were grouped as complex. Admission length, tracheostomy-related complications, in-hospital mortality, and 30-day readmissions were recorded among complex and non-complex patients.

RESULTS

A total of 238 children were included. Mean age at tracheostomy was 39.9 months (SD: 61.3), 51% were male and 51% were complex. Complex patients were younger at admission (29.9 vs. 46.8 months, P = .03), more likely to have respiratory failure (81% vs. 53%, P < .001) and more often required mechanical ventilation at discharge (86% vs. 67%, P < .001). An additional 33 days after placement was required for complex children (95% CI: 14-51, P = .001) and this group had more deaths (8% vs. 1%, P = .02); however, both groups had similar complication and readmission rates (P > .05). Total charges were higher among complex patients ($700,267 vs. $338,937, P < .001). Parametric survival analysis identified mechanical ventilation and patient complexity interacting to predict post-tracheostomy admission length.

CONCLUSIONS

Hospital discharge after pediatric tracheostomy was associated with patient complexity and further influenced by mechanical ventilation. Recognition that cardiac surgery, sepsis, or TPN can predict poorer perioperative outcomes can provide quality improvement strategies for these vulnerable children.

Multidisciplinary Safety Recommendations After Tracheostomy During COVID-19 Pandemic: State of the Art Review

OBJECTIVE

In the chronic phase of the COVID-19 pandemic, questions have arisen regarding the care of patients with a tracheostomy and downstream management. This review addresses gaps in the literature regarding posttracheostomy care, emphasizing safety of multidisciplinary teams, coordinating complex care needs, and identifying and managing late complications of prolonged intubation and tracheostomy.

DATA SOURCES

PubMed, Cochrane Library, Scopus, Google Scholar, institutional guidance documents.

REVIEW METHODS

Literature through June 2020 on the care of patients with a tracheostomy was reviewed, including consensus statements, clinical practice guidelines, institutional guidance, and scientific literature on COVID-19 and SARS-CoV-2 virology and immunology. Where data were lacking, expert opinions were aggregated and adjudicated to arrive at consensus recommendations.

CONCLUSIONS

Best practices in caring for patients after a tracheostomy during the COVID-19 pandemic are multifaceted, encompassing precautions during aerosol-generating procedures; minimizing exposure risks to health care workers, caregivers, and patients; ensuring safe, timely tracheostomy care; and identifying and managing laryngotracheal injury, such as vocal fold injury, posterior glottic stenosis, and subglottic stenosis that may affect speech, swallowing, and airway protection. We present recommended approaches to tracheostomy care, outlining modifications to conventional algorithms, raising vigilance for heightened risks of bleeding or other complications, and offering recommendations for personal protective equipment, equipment, care protocols, and personnel.

IMPLICATIONS FOR PRACTICE

Treatment of patients with a tracheostomy in the COVID-19 pandemic requires foresight and may rival procedural considerations in tracheostomy in their complexity. By considering patient-specific factors, mitigating transmission risks, optimizing the clinical environment, and detecting late manifestations of severe COVID-19, clinicians can ensure due vigilance and quality care.

Decreasing Telephone Calls for Tympanostomy Tube Otorrhea: A Pilot Study

The "Clinical Practice Guideline: Tympanostomy Tubes in Children" published in 2013 by the American Academy of Otolaryngology-Head and Neck Surgery Foundation encourages that an "educational video, or other teaching aid, should be developed to illustrate how parents/caregivers" may manage postoperative complications such as tube otorrhea; however, the current literature is devoid of such patient safety and quality improvement measures. Our objective was to develop an effective educational model to assist parents and caregivers in understanding the signs and symptoms of tympanostomy tube (TT) otorrhea and how to independently institute the appropriate otologic treatment. A 3.5 × 2-inch instructional card was designed to illustrate TT otorrhea and describe the subsequent steps necessary to obtain and institute the appropriate medical therapy. This was distributed to caregivers of all patients undergoing TT placement in September 2016; patients undergoing TT placement in May 2016 served as the preintervention control cohort. Group comparisons were made before and after implementation of the educational model by number of telephone calls our clinic triaged regarding untreated TT otorrhea, as documented within the electronic medical record. A total of 30 sets of TT were placed in September 2016, compared to 27 sets of TT in May 2016. Postoperatively, a run chart revealed a significant shift (ie, 7 consecutive points) in the number of telephone calls received (16-5 calls) after establishment of the proposed educational model. This clinical experience demonstrates the utility of patient-driven management of TT otorrhea through ancillary educational material. Given the superiority of topical otic therapy, continued translation efforts are needed for continued focus on practice implementation and dissemination.
