ASPS Research, Evidence-Based Practice & Clinical Outcomes 2 — Questions and Answers
Question 1: The BODY-Q is a validated patient-reported outcome instrument designed to measure outcomes after:
- Body contouring surgery (Correct answer)
- Breast augmentation only
- Rhinoplasty and facial procedures
- Hand and upper extremity reconstruction
Correct answer: Body contouring surgery
The BODY-Q is specifically developed and validated for patients undergoing body contouring procedures, including massive weight loss surgery.
Question 2: In outcomes research, the Clavien-Dindo classification system is used to standardize reporting of:
- Anesthetic risk stratification
- Surgical complications by severity (Correct answer)
- Patient-reported pain scores
- Cosmetic result satisfaction grades
Correct answer: Surgical complications by severity
The Clavien-Dindo classification grades surgical complications from Grade I (minor deviation from normal recovery) to Grade V (death), enabling standardized reporting.
Question 3: When comparing outcomes between two patient groups, a p-value of 0.03 indicates:
- There is a 3% chance the null hypothesis is true
- The probability of observing the results by chance alone is 3% (Correct answer)
- The treatment is 97% effective
- The result is clinically meaningful
Correct answer: The probability of observing the results by chance alone is 3%
A p-value of 0.03 means there is a 3% probability of observing results at least as extreme as those seen if the null hypothesis were true.
Question 4: A systematic review of liposuction outcomes that pools quantitative data from multiple studies using statistical methods is specifically called a:
- Narrative review
- Scoping review
- Meta-analysis (Correct answer)
- Integrative review
Correct answer: Meta-analysis
A meta-analysis statistically combines quantitative results from multiple studies to produce a more precise pooled estimate of effect.
Question 5: Which registry maintained by ASPS collects prospective data on patient outcomes and complications in plastic surgery?
- TRAM Registry
- TOPS (Tracking Operations and Outcomes for Plastic Surgeons) (Correct answer)
- NSQIP Plastic Surgery Module
- ABPS Outcomes Database
Correct answer: TOPS (Tracking Operations and Outcomes for Plastic Surgeons)
TOPS (Tracking Operations and Outcomes for Plastic Surgeons) is the ASPS quality outcomes registry designed to collect prospective procedural and outcome data.
Question 6: In a study of facelift outcomes, confounding occurs when:
- Some patients are lost to follow-up after surgery
- A third variable (e.g., smoking) is associated with both exposure and outcome (Correct answer)
- The study lacks a control group for comparison
- Researchers are not blinded to treatment allocation
Correct answer: A third variable (e.g., smoking) is associated with both exposure and outcome
Confounding occurs when an extraneous variable is associated with both the independent variable (exposure) and dependent variable (outcome), distorting the true relationship.
Question 7: The minimal clinically important difference (MCID) in patient-reported outcomes represents:
- The maximum acceptable complication rate for a procedure
- The smallest change in a score that patients perceive as meaningful (Correct answer)
- The threshold at which statistical significance is achieved
- The difference between two validated outcome instruments
Correct answer: The smallest change in a score that patients perceive as meaningful
MCID defines the smallest change in a PRO score that patients actually perceive as beneficial, bridging the gap between statistical and clinical significance.
