Regional and hospital variation in commonly performed paediatric otolaryngology procedures in the Netherlands: a population-based study of healthcare utilisation between 2016 and 2019.

Objective: In the past few decades, there has been an increase in high-quality studies providing evidence on the effectiveness of commonly performed procedures in paediatric otolaryngology. We believe that now is the time to re-evaluate the care process. We aimed to analyse (1) the regional variation in incidence and referrals of adenoidectomies, tonsillectomies and ventilation tube insertions in children in the Netherlands between 2016 and 2019, (2) whether regional surgical rates, referral rates and in-hospital surgical rates were associated with one another, and (3) the hospital variation in healthcare costs, which indicates the utilisation of resources.

Uniform Registration Agreements on Cholesteatoma Care: A Nationwide Consensus Procedure.

Background: To coordinate and align the content for registration of cholesteatoma care.

Methods: Systematic Delphi consensus procedure, consisting three rounds: two written sessions followed by a face-to-face meeting. Before this procedure, input on important patient outcomes was obtained.

Awareness and Management of Dysphagia in Dutch Intensive Care Units: A Nationwide Survey.

Dysphagia is a common problem in the intensive care unit (ICU), yet no national guidelines on dysphagia prevention, screening, and management exist. We performed a survey to learn which strategies are commonly being used in Dutch ICUs. A survey was developed based on current literature and experts' opinions.

A new method for measuring mechanical properties of laryngeal mucosa.

A study of the effect of exogenous hazardous agents or conditions on the mechanical characteristics of vocal fold mucosa should meet three methodological criteria. 1) The outer surface of the mucosa should be exposed to the agent or condition while the inner surface is exposed to a physiological environment. 2) Even slight changes in mechanical characteristics should be detected.

Laryngeal mucosa elasticity and viscosity in high and low relative air humidity.

In earlier work we showed that low relative humidity (RH) of inhaled air causes acoustic voice parameters such as jitter and shimmer to deteriorate. Other authors have shown negative effects on vocal efficiency. To explain these changes in the mechanical properties of the vocal folds, the effects of changes in RH of the air passing over microdissected mucosa of sheep larynges were studied.
