ABCS Data Analysis & Reporting 3

Question 1

A cosmetic surgery practice wants to determine if there is a relationship between patient BMI and postoperative wound healing complications. Which statistical test is most appropriate?

Accepted Answer

Pearson correlation

Answer

Pearson correlation measures the linear relationship between two continuous variables such as BMI and a continuous healing score.

Question 2

In cosmetic surgery data reporting, 'incidence' refers to which of the following?

Accepted Answer

The proportion of new cases arising in a population over a defined time period

Answer

Incidence specifically counts new cases occurring within a specified time frame in a defined population.

Question 3

A board-certified cosmetic surgeon's data dashboard shows an upward control chart violation (8 consecutive points above the mean). What does this signal?

Accepted Answer

A statistically significant shift in the process

Answer

Eight consecutive points on one side of the mean is a classic Western Electric rule violation, signaling a non-random process shift.

Question 4

Which data quality dimension is most at risk when a cosmetic practice relies solely on insurance billing codes to track complication rates?

Accepted Answer

Accuracy

Answer

Billing codes may be up-coded, down-coded, or not reflect the clinical reality, compromising the accuracy of complication data.

Question 5

For a cosmetic surgery outcomes database, what does a high intraclass correlation coefficient (ICC) indicate?

Accepted Answer

Strong agreement between raters or repeated measurements

Answer

ICC measures reliability and consistency; a high ICC indicates strong agreement among raters or across repeated measurements.
