Insights
Patients from disadvantaged neighborhoods face longer wait times for transcatheter aortic valve replacement (TAVR). This study found neighborhood disadvantage correlates with prolonged TAVR delays, impacting patient outcomes.
Area of Science:
- Cardiology
- Health Disparities Research
- Public Health
Background:
- Transcatheter aortic valve replacement (TAVR) is a growing procedure for aortic valve replacement.
- Extended wait times for TAVR are linked to increased patient mortality.
- Understanding factors influencing TAVR wait times is crucial for improving patient care.
Purpose of the Study:
- To investigate the association between neighborhood disadvantage and time to TAVR.
- To determine if socioeconomic factors impact TAVR accessibility and timeliness.
Main Methods:
- Retrospective analysis of a prospectively maintained database of 708 patients undergoing TAVR (January 2019 - January 2024).
- Area Deprivation Index (ADI) calculated using patient addresses via the Neighborhood Atlas.
- Time to TAVR defined as the period from initial structural heart team contact to valve implantation.
Main Results:
- No significant correlation between TAVR wait times and ADI was observed for patients within one or two standard deviations of the mean.
- A positive correlation was found between prolonged TAVR wait times (greater than three standard deviations from the mean) and higher ADI scores.
- This suggests neighborhood disadvantage is linked to longer delays for TAVR in certain patient groups.
Conclusions:
- Patients residing in highly disadvantaged neighborhoods experience significantly longer wait times for TAVR.
- The study did not find evidence that socioeconomic status-related follow-up barriers explain these prolonged TAVR delays.
Abstract:
Introduction Transcatheter aortic valve replacement (TAVR) is an increasingly used form of aortic valve replacement. Prolonged wait time prior to TAVR is associated with an increased mortality rate. This study examines whether the extent of neighborhood disadvantage of patients has any impact on time to TAVR, and if so, to what degree. Methods After institutional review board approval, we conducted a retrospective review of a prospectively maintained database to assess time to TAVR. Time to TAVR was defined from first contact with the structural heart team until implant. Inclusion criteria involved patients undergoing TAVR from January 2019 until January 2024. The area deprivation index (ADI) was determined utilizing the patient's listed home address and the Neighborhood Atlas developed by the Center for Health Disparities Research of the University of Wisconsin School of Medicine and Public Health. Results The patient population included 708 patients. No significant correlation between time to TAVR and ADI was found for patients with a time to TAVR one or two standard deviations from the mean. For patients with time to TAVR greater than three standard deviations from the mean, positive correlations were found between time to TAVR and ADI, as well as time to TAVR and national percentile. The national percentile was obtained by comparing ADI scores for the entire United States, which were then ranked and divided into percentiles. Conclusions Patients from the most disadvantaged neighborhoods experience a longer time to TAVR than others. We hypothesized that a low socioeconomic status would potentially cause barriers with follow-up; however the prolonged time to TAVR in this study was not shown to be secondary to that.
