A pilot study found that many patients undergoing total joint arthroplasty were willing to modify risk factors like obesity and smoking before surgery. Over 40% met goals, with some proceeding to replacement.
Area of Science:
- Orthopedic surgery
- Patient risk stratification
Background:
- Morbid obesity, smoking, and uncontrolled diabetes mellitus are linked to poor outcomes in total joint arthroplasty.
- No studies have reported on risk reduction strategies for these patients.
Purpose of the Study:
- To evaluate the effectiveness of a risk reduction strategy in patients undergoing total joint arthroplasty.
- To determine patient willingness and ability to modify risk factors before surgery.
Main Methods:
- Retrospective pilot review of a 3-month period implementing a risk reduction protocol.
- Risk factors defined as Body Mass Index (BMI) >40, Hemoglobin A1c (HbA1c) >8.0, and tobacco use.
- Outcomes evaluated in the subsequent 3-month period for 19 patients.
Main Results:
- 65.5% of at-risk patients followed the protocol.
- 57.9% improved their risk factors.
- 42.1% met surgical goals, with 21% undergoing joint replacement.
Conclusions:
- A significant proportion of patients are willing and able to modify pre-operative risk factors.
- Risk reduction strategies may improve surgical candidacy and outcomes for total joint arthroplasty patients.
