Assessment of Medical and Social Risk Factors Before Arthroplasty in Argentina: A Poll of Argentinian Hip and Knee Association (ACARO) Members.

Background: Assessment of risk factors is crucial for lowering complication rates and costs of hip and knee arthroplasty. The objective of this study was to assess if members of the Argentinian Hip and Knee Association (ACARO) are influenced by such risk factors when planning surgery.
Methods: In 2022, a survey was distributed as an electronically based questionnaire to 370 members of the ACARO. A descriptive analysis was performed on 166 proper answers (44.9%).
Results: There were 68% of the respondents who were specialists in joint arthroplasty and 32% practiced general orthopedics. A large number had large volumes at private hospitals without service/residents and 48.2% had been in practice for more than 15 years. Of the responding surgeons, 99% routinely performed a preoperative reversible risk factors evaluation that considered diabetes, malnutrition, weight, and smoking, and 95% canceled/postponed the surgery for abnormalities. Malnutrition was important for 79% of the polled with blood albumin being used by 69.3%. Fall risk assessment was performed by 60.2% of the surgeons. Only 44% of the surgeons felt free to choose the implant for the arthroplasty, possibly because 69.9% work for a capitated system. Important delays for surgery were reported by 63.9 and 84.3% had waiting lists. 74.7% of the polled noted physical or psychological deterioration during such delays.
Conclusion: Socioeconomic factors firmly impact on the accessibility to arthroplasty in Argentina. Despite these barriers, the qualitative analysis of this poll let us demonstrate greater awareness of preoperative risk factors, especially diabetes as the most reported comorbidity.
