Effect of the coronavirus disease 2019 pandemic on paediatric bilateral myringotomy and tube insertion rates in New Brunswick, Canada.

OBJECTIVE: To assess the effect of the coronavirus disease 2019 pandemic on paediatric bilateral myringotomy and tube insertion rates in New Brunswick, Canada. METHODS: All paediatric bilateral myringotomy and tube insertion cases from 1 July 2015 through 30 June 2021 were provided by New Brunswick Medicare. The numbers of otolaryngologists, cataract surgical procedures, total hip arthroplasties and thyroidectomies were collected to assess the availability of operating theatres and otolaryngologists. Negative binomial logarithmic regressions were used for analyses. RESULTS: Of the 5175 paediatric bilateral myringotomy and tube insertion cases that were included, the bilateral myringotomy and tube insertion rate significantly decreased by 2.9 times (p < 0.001) during the pandemic. Thyroidectomies, cataract surgical procedures and total hip arthroplasties did not significantly decrease. The number of otolaryngologists increased (20 vs 16-17). CONCLUSION: Paediatric bilateral myringotomy and tube insertion rates significantly decreased during the pandemic. This cannot be accounted for by reduced otolaryngologists or operating theatre availability. The paediatric bilateral myringotomy and tube insertion rate decrease is likely due to public health measures reducing the transmission of upper respiratory tract infections, resulting in fewer indications for paediatric bilateral myringotomy and tube insertion.

Canadian Rhinology Working Group consensus statement: biologic therapies for chronic rhinosinusitis.

BACKGROUND: Recent evidence suggests that biologic therapy with targeted activity within the Type 2 inflammatory pathway can improve the clinical signs and symptoms of chronic rhinosinusitis with nasal polyposis (CRSwNP). There remains a population in CRSwNP that despite medical therapy and endoscopic sinus surgery have persistent signs and symptoms of disease. Therefore, biologics, monoclonal antibody agents, could be beneficial therapeutic treatments for these patients. There have been eight randomized, double-blind, placebo-controlled trails performed for CRSwNP targeted components of the Type 2 inflammatory pathway, notably interleukin (IL)-4, IL-5 and IL-13, IL-5R, IL-33, and immunoglobulin (Ig)E. However, there are no formal recommendations for the optimal use of biologics in managing Chronic Rhinosinusitis (CRS) within the Canadian health care environment. METHODS: A Delphi Method process was utilized involving three rounds of questionnaires in which the first two were completed individually online and the third was discussed on a virtual platform with all the panelists. 17 fellowship trained rhinologists across Canada evaluated the 28 original statements on a scale of 1-10 and provided comments. A rating within 1-3 indicated disagreement, 8-10 demonstrated agreement and 4-7 represented being neutral towards a statement. All ratings were quantitively reviewed by mean, median, mode, range and standard deviation. Consensus was defined by removing the highest and lowest of the scores and using the "3 point relaxed system". RESULTS: After three rounds, a total of 11 statements achieved consensus. This white paper only contains the final agreed upon statements and clear rationale and support for the statements regarding the use of biologics in patients with CRS. CONCLUSION: This white paper provides guidance to Canadian physicians on the use of biologic therapy for the management of patients with CRS, but the medical and surgical regimen should ultimately be individualized to the patient. As more biologics become available and additional trials are published we will provide updated versions of this white paper every few years.

Comparing surgical trays with redundant instruments with trays with reduced instruments: a cost analysis.

BACKGROUND: When prearranged standard surgical trays contain instruments that are repeatedly unused, the redundancy can result in unnecessary health care costs. Our objective was to estimate potential savings by performing an economic evaluation comparing the cost of surgical trays with redundant instruments with surgical trays with reduced instruments ("reduced trays"). METHODS: We performed a cost-analysis from the hospital perspective over a 1-year period. Using a mathematical model, we compared the direct costs of trays containing redundant instruments to reduced trays for 5 otolaryngology procedures. We incorporated data from several sources including local hospital data on surgical volume, the number of instruments on redundant and reduced trays, wages of personnel and time required to pack instruments. From the literature, we incorporated instrument depreciation costs and the time required to decontaminate an instrument. We performed 1-way sensitivity analyses on all variables, including surgical volume. Costs were estimated in 2013 Canadian dollars. RESULTS: The cost of redundant trays was $21 806 and the cost of reduced trays was $8803, for a 1-year cost saving of $13 003. In sensitivity analyses, cost savings ranged from $3262 to $21 395, based on the surgical volume at the institution. Variation in surgical volume resulted in a wider range of estimates, with a minimum of $3253 for low-volume to a maximum of $52 012 for high-volume institutions. INTERPRETATION: Our study suggests moderate savings may be achieved by reducing surgical tray redundancy and, if applied to other surgical specialties, may result in savings to Canadian health care systems.

Simulation-based otolaryngology - head and neck surgery boot camp: 'how I do it'.

BACKGROUND: In otolaryngology, surgical emergencies can occur at any time. An annual surgical training camp (or 'boot camp') offers junior residents from across North America the opportunity to learn and practice these skills in a safe environment. The goals of this study were to describe the set-up and execution of a simulation-based otolaryngology boot camp and to determine participants' confidence in performing routine and emergency on-call procedures in stressful situations before and after the boot camp. METHODS: There were three main components of the boot camp: task trainers, simulations and an interactive panel discussion. Surveys were given to participants before and after the boot camp, and their confidence in performing the different tasks was assessed via multiple t-tests. RESULTS: Participants comprised 22 residents from 12 different universities; 10 of these completed both boot camp surveys. Of the nine tasks, the residents reported a significant improvement in confidence levels for six, including surgical airway and orbital haematoma management. CONCLUSION: An otolaryngology boot camp gives residents the chance to learn and practice emergency skills before encountering the emergencies in everyday practice. Their confidence in multiple skillsets was significantly improved after the boot camp. Given the shift towards competency-based learning in medical training, this study has implications for all surgical and procedural specialties.

Squeeze bottle versus saline spray after endoscopic sinus surgery for chronic rhinosinusitis: a pilot multicentre trial.

BACKGROUND: There is a need for controlled trials to guide the perioperative management of patients undergoing endoscopic sinus surgery (ESS). The authors performed a pilot multicenter trial to compare two types of saline delivery devices in this population. METHODS: Patients were randomized to high volume saline irrigation with a squeeze bottle and low volume saline spray after ESS in patients with chronic rhinosinusitis (CRS). Surgeons were blinded to treatment, and one-month postoperative scores for sinonasal outcomes [Sinonasal Outcome Test-22 (SNOT-22)] scale, nasal and sinus symptom score (NSS), and perioperative sinus endoscopy (POSE) scale were compared with preoperative scores. RESULTS: Nine centers provided data for 86 patients. All three outcomes measures improved significantly for both groups. Saline spray: SNOT-22 48.8 versus. 23.7, treatment effect 25.1 (95% confidence interval [CI], 17.9-32.2), POSE 21.1 versus. 8.4, treatment effect 12.7 (95% CI, 9.2-16.1), and NSS 8.2 versus 5.0, treatment effect 3.1 (95% CI, 1.4-4.9) pre- and postoperatively, respectively (all p < 0.0001). Squeeze bottle: SNOT-22 49.5 versus 23.6, treatment effect 25.9 (95% CI, 20.3-31.6), POSE 18.6 versus 9.2, treatment effect 9.3, (95% CI 6.7-12.0), and NSS 9.0 versus 5.7, treatment effect 3.3 (95% CI, 2.3-4.3) pre- and postoperatively, respectively (all p < 0.0001). Analysis of variance did not identify a difference between the two treatment groups. Subgroup analysis based on preoperative disease severity did not change the nonassociation of saline bottle with outcome measures. Post hoc sample size calculation determined that 176 patients is required to detect an 8.9-point difference in SNOT-22 scores. CONCLUSION: In this pilot multicenter trial examining patients with chronic rhinosinusitis undergoing ESS, both squeeze bottle and saline spray showed significant improvement in SNOT-22, POSE, and NSS scores at one-month postoperatively. Because the study was nonpowered, we cannot rule out a potential difference between the two treatment groups.

A vegetarian diet rich in soybean products compromises iron status in young students.

The iron status of young Chinese Buddhist vegetarians (23 men and 32 women) and nonvegetarian students (20 men and 39 women from a medical college) was investigated by dietary assessment of iron intake and hematological measurement of biochemical indices including hemoglobin, plasma iron, transferrin, transferrin saturation and plasma ferritin. A characteristic of the vegetarian diet in this study was the replacement of meat by soybean products. Results of the dietary assessment showed that the average iron density of the diets ranged from 1.9 to 2.2 mg/MJ, with no difference between the vegetarian and nonvegetarian diets. Daily iron intake was similar in both vegetarian and nonvegetarian men. However, iron intake was significantly higher in female vegetarians than nonvegetarians, averaging 104 and 78% of the RDA, respectively. Results of blood analysis showed that, for both sexes, the median plasma ferritin concentration of the vegetarians (male 47 micrograms/L and female 12 micrograms/L) was about half the level of the nonvegetarians (male 91 micrograms/L and female 27 micrograms/L). Occurrence and risk of iron deficiency are more prevalent in vegetarians. Correlation between plasma ferritin concentration and years of vegetarian practice in vegetarian men was marginally significant (r = -0.38, P = 0.077). We conclude that a vegetarian diet that is rich in soybean products and restricted in animal foods is limited in bioavailable iron and is not adequate for maintaining iron balance in men and women.

Hemostatic factors and blood lipids in young Buddhist vegetarians and omnivores.

A comparison was made between the hemostatic and lipid profiles of 55 young Chinese Buddhist vegetarians (23 men, 32 women) and 59 Chinese medical students (20 men, 39 women) aged 20-30 y. The modern Buddhist vegetarian diet is high in carbohydrate (63% of energy in men, 58% in women) and has a high polyunsaturated-saturated fatty acid ratio, with moderate fat content (25% for men, 30% for women). Rice and soybean proteins are the major protein sources. This study demonstrated that the major beneficial effects of a modern Buddhist vegetarian diet are on blood concentrations of cholesterol, the ratio of apolipoprotein A-I to apolipoprotein B, glucose, and uric acid, but not on most hemostatic factors studied, which included fibrinogen, factor VIIc, factor VIIIc, and plasminogen. Vegetarian men had significantly higher concentrations of antithrombin III than nonvegetarian men.

[Clinical evaluation of aggressive nutritional care to head and neck cancer patients during radiation therapy].

Anorexia, dysphagia, and dysgeusia are the most prevalent symptoms in head and neck cancer patients during radiation therapy. The patients, who were in poor general condition, suffered marked loss of body weight and consequently were unable to tolerate further anti-cancer treatments. Aggressive nutritional support to the head and neck cancer patients was started in April, 1986 to improve the general condition of these patients in our hospital. The physiological condition of 152 patients who underwent nutritional support were evaluated as a study group (Group I) between August 1986 and May 1987. Group II, 165 patients without nutritional care were evaluated as a control group between August 1985 and May 1986. In Group I, oral supplementary diets or enteral feedings were provided as nutritional support to all of the anorectic patients. Anthropometric measurement and laboratory data were collected in both groups at the several time points. An average of 1.1 kilogram (Kg) and 3.5Kg body weight loss was observed in Group I and Group II, respectively (P less than 0.005). In patients diagnosed with nasopharyngeal carcinoma, the average duration of radiation treatment was 11 days shorter in Group I than that in Group II (42 vs 53 days). In conclusion, aggressive nutritional care performed by a group of clinical staff, which included doctors (radiation oncologist), dietitians and oncologic nurses, was sufficient to improve the general condition of the head and neck cancer patients during radiation therapy and to therefore increase the recovery rate of these patients after radiation treatments.(ABSTRACT TRUNCATED AT 250 WORDS)
