Medical professionals can use mass-casualty triage systems to assist them in prioritizing patients from mass-casualty incidents (MCIs). Correct triaging of victims will increase their chances of survival. Determining the triage system that has the best performance has proven to be a difficult question to answer. The Advanced Prehospital Triage Model (Modelo Extrahospitalario de Triaje Avanzado; META) and Sort, Assess, Lifesaving Interventions, Treatment/Transport (SALT) algorithms are the most recent triage techniques to be published. The present study aimed to evaluate the META and SALT algorithms’ performance and statistical agreement with various standards. The secondary objective was to determine whether these two MCI triage systems predicted patient outcomes, such as mortality, length-of-stay, and intensive care unit (ICU) admission.

This retrospective study used patient data from the trauma registry of an American College of Surgeons Level 1 trauma center, from January 1, 2018 through December 31, 2020. The sensitivity, specificity, and statistical agreement of the META and SALT triage systems to various standards (Revised Trauma Score [RTS]/Sort Triage, Injury Severity Score [ISS], and Lerner criteria) when applied using trauma patients. Statistical analysis was used to assess the relationship between each triage category and the secondary outcomes.

A total of 3,097 cases were included in the study. Using Sort triage as the standard, SALT and META showed much higher sensitivity and specificity in the Immediate category than for Delayed (Immediate sensitivity META 91.5%, SALT 94.9%; specificity 60.8%, 72.7% versus Delayed sensitivity 28.9%, 1.3%; specificity 42.4%, 28.9%). With the Lerner criteria, in the Immediate category, META had higher sensitivity (77.1%, SALT 68.6%) but lower specificity (61.1%) than SALT (71.8%). For the Delayed category, SALT showed higher sensitivity (META 61.4%, SALT 72.2%), but lower specificity (META 75.1%, SALT 67.2%). Both systems showed a positive, though modest, correlation with ISS. For SALT and META, triaged Immediate patients tended to have higher mortality and longer ICU and hospital lengths-of-stay.

Both META and SALT triage appear to be more accurate with Immediate category patients, as opposed to Delayed category patients. With both systems, patients triaged as Immediate have higher mortality and longer lengths-of-stay when compared to Delayed patients. Further research can help refine MCI triage systems and improve accuracy.

This study aimed to evaluate the readability and quality of current online information on Bell's palsy.

A Google search using the terms ‘Bell's palsy’ and ‘facial palsy’ was performed separately. The first three pages of results were analysed. Readability was assessed using Flesch Reading Ease Score, Flesch–Kincaid Grade Level, the Gunning-Fog Index and the Simple Measure of Gobbledygook. Quality was assessed using the Discern tool. Spearman's correlation between quality and readability was calculated.

A total of 31 websites met the inclusion criteria. The mean Flesch Reading Ease Score, Flesch–Kincaid Grade Level, the Gunning Fox Index and the Simple Measure of Gobbledygook scores were 52.45 (95 per cent confidence interval = 47.01–57.86), 10.50 (95 per cent confidence interval = 9.42–11.58), 12.76 (95 per cent confidence interval = 11.68–13.85) and 9.36 (95 per cent confidence interval = 8.52–10.20), respectively. The average Discern score was 44 (95 per cent confidence interval = 40.88–47.12). A negligible correlation was noted between the Discern and Flesch Reading Ease Score (rs = −0.05, p = 0.80).

Online information on Bell's palsy is generally of fair quality but is written above the recommended reading age guidance in the UK.

There is limited understanding amongst patients and parents of paediatric patients regarding adenoidectomy. Most patients access health-related information online. The aim of this study was to assess the suitability of online information on adenoidectomy.

The term ‘adenoid’ was used to search Google, and the first 50 websites identified were screened. For each website, the readability and quality were assessed.

Of the 41 websites that met the inclusion criteria, the mean readability scores corresponded to ‘difficult to read’ and university-level reading categories. For the quality of the websites, the mean score corresponded to ‘fair’ with 39 per cent of the websites containing either ‘poor’ or ‘very poor’ quality data. The ENT UK information is one of the most readable and reliable online resources.

The online information on adenoidectomy is largely set at an inappropriate readability level and of variable quality. Surgeons should consider assisting their patients with online searches regarding adenoidectomy.

This study aimed to compare the diagnostic reliabilities of transient evoked otoacoustic emissions, automated auditory brainstem responses and brainstem auditory evoked responses for detecting hearing loss, and to use the information regarding hearing level of automated auditory brainstem responses for planning rehabilitation.

A total of 144 high-risk infants (288 ears) completed the 3 hearing tests. The sensitivity and specificity of otoacoustic emissions and automated auditory brainstem responses were compared using the chi-square test.

Automated auditory brainstem response was the most reliable test of hearing levels, with a sensitivity of 91.7 per cent and specificity of 92.1 per cent; the sensitivity of otoacoustic emissions was 78.7 per cent and the specificity was 88.8 per cent.

Automated auditory brainstem responses have acceptably high sensitivity and specificity. Additionally, the hearing level from automated auditory brainstem responses can help the screeners explain to the parents the importance of further diagnosis and rehabilitation.

In order to achieve a faster and more reliable anterior rhinomanometric evaluation, nasal skin was prepared using benzoin tincture solution, which provides simpler and better adhesion of the foam tape to the nasal skin.

Two consecutive anterior rhinomanometry measurements were made, one with and one without benzoin tincture application.

The average time taken to perform classic foam tape anterior rhinomanometry without benzoin tincture application was 281.32 seconds, and the average coefficients of variation for the right and left passages were 7.48 and 7.59 per cent, respectively. When benzoin tincture was used, the average time taken for completion of the tests was 121.24 seconds, and the average coefficients of variation for the right and left passages were 2.17 and 2.32 per cent.

The use of benzoin tincture to clean the nasal skin before placing foam tape shortens the procedure duration and significantly increases test reliability.
