Summary
This study found significant variations in tympanoplasty costs and operative times across surgeons and hospitals. Addressing these cost differences can improve healthcare value and reduce waste.
Area of Science:
- Otolaryngology
- Health Services Research
- Health Economics
Background:
- Tympanoplasty is a common otologic surgical procedure.
- Understanding cost and operative time variations is crucial for healthcare efficiency.
Purpose of the Study:
- To identify the costs and operative times associated with tympanoplasty.
- To evaluate factors influencing variations in cost and time.
Main Methods:
- Retrospective cohort study of 487 tympanoplasties from 2008-2016 across 13 hospitals.
- Activity-based accounting system used to determine costs and operative times.
- Statistical analysis including Spearman correlation and Kruskal-Wallis/Dunn's tests.
Main Results:
- Mean operative time was 85.8 minutes and mean cost was $3491.
- Anesthesia cost and operative time were significant factors influencing total cost.
- Laser utilization and artificial graft materials represented major supply costs.
Conclusions:
- Significant variation in tympanoplasty costs exists among surgeons and hospitals.
- Reducing cost variation can enhance healthcare value and minimize waste.
- Further research into cost drivers may optimize resource allocation.

What is Variation?
18.5K
Apart from the measures of central tendency, distribution, outliers, and the changing characteristics of data with time, an important characteristic of any data set is its variation or spread. In some data sets, the data values are concentrated closely near the mean; in others, the data values are more widely spread out from the mean.
The range, standard deviation, standard error, and variance are the different measures of variation.
Range: The range is the difference between its maximum and...

Variation

An important characteristic of any set of data is the variation in the data. In some data sets, the data values are concentrated closely near the mean; in other data sets, the data values are more widely spread out from the mean. The most common measure of variation, or spread, is the standard deviation, which is the square root of variance.

Protein Networks
4.6K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Conservative Site-specific Recombination and Phase Variation
6.8K
Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.
The recognition sites for Cre recombinase called LoxP...

Variation of Atmospheric Pressure
4.1K
Change in atmospheric pressure with height is particularly interesting. The decrease in atmospheric pressure with increasing altitude is due to the decreasing gravitational force per unit area as we move away from the surface of the earth.
Assuming the air temperature is constant at a given altitude and that the ideal gas law of thermodynamics describes the atmosphere to a good approximation, one can find the variation of atmospheric pressure with height.
Let p(y) be the atmospheric pressure at...

Comparing Copy Number Variations and SNPs
18.8K
Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
