High in-hospital preoperative anxiety levels are not associated with an increased length of stay or readmission following primary shoulder arthroplasty

Abstract

Background

Anxiety is prevalent in our society, affecting all facets of patients’ lives. There is, however, a paucity of literature exploring how anxiety extends into the orthopedic perioperative setting. We sought to analyze a subset of patients undergoing primary shoulder arthroplasty to determine whether correlations exist between anxiety, patient characteristics, time spent in the hospital, and likelihood of returning to the hospital after discharge.

Methods

After obtaining institutional review board approval, our hospital prospectively identified and approached all patients undergoing total shoulder arthroplasty between February and June of 2023. Patients completed the Visual Analog Scale for Anxiety (VAS-A) and Amsterdam Preoperative Anxiety and Information Scale (APAIS), two validated tools used to assess preoperative anxiety levels and need for information, in the preoperative holding area before surgery. Patient demographics, hospital length of stay (LOS), and 30-day readmission rate were collected and analyzed.

Results

A total of 79 patients were enrolled. Nineteen percent of patients were found to be anxious using the APAIS tool, while 37.7% of patients were found to be anxious using the VAS-A tool. No significant correlation was found between APAIS or VAS-A anxiety scoring and hospital LOS. No significant correlation was found between APAIS or VAS-A anxiety scoring and 30-day readmission rate. A significant correlation was found between APAIS anxiety scoring and body mass index (BMI), as well as VAS-A scoring and BMI. However, no significant correlation was found between BMI and hospital LOS or between BMI and 30-day readmission rate.

Conclusion

Our study did not find a statistically significant correlation between immediate preoperative anxiety levels in patients undergoing shoulder arthroplasty and their length of stay or 30-day readmission rate. We did discover a linear relationship between patient BMI and their preoperative anxiety scores; however, no significant direct correlation was found between a patient’s BMI and their length of stay or their 30-day readmission rate. Our findings suggest that higher levels of preoperative anxiety should not preclude a patient from the benefits of consideration of early discharge planning such as same-day total shoulder replacement.
