For NICM patients with recurrent, refractory VAs despite previous ablation, effective arrhythmia control can safely be achieved with subsequent ablation, although >1 repeat procedure with adjunctive ablation is often required, especially with MMS.
Introduction:
The Canadian Study on Health and Aging (CSHA) Frailty Scale was included in the National Cardiovascular Data Registry’s (NCDR) CathPCI registry beginning April 2018. The value of this frailty assessment as an independent predictor of hospital readmission is unknown.
Methods:
A retrospective analysis was performed of patients who underwent PCI within the University of North Carolina Medical System between 04/2018 and 12/2018. Outcome data was obtained from our electronic medical record data repository and procedural data from the institutional CathPCI registry. The primary outcome was repeat hospital admission within 1 year of PCI. Significant covariates (p<0.05) in the univariate analyses were considered for inclusion in the multivariate model. Multivariate logistic regression was then performed to determine if CSHA Frailty Scale was an independent predictor of hospital readmission.
Results:
1,592 subjects were identified with 367 readmission events. Patients in the readmission cohort were older, had a higher frailty score, and had more comorbidities. Table 1 summarizes the comorbidities included in the logistic regression. CSHA Frailty Scale did not meet significance requirements (P<.05) to be independently associated with readmission. Covariates that were significant independent predictors of readmission included age (OR 1.024, 95% CI 1.012-1.036); cerebrovascular disease (OR 1.688, 95% CI 1.234-2.308); dialysis (OR 2.983, 95% CI, 1.583-5.622); and CHF (OR 2.465, 95% CI, 1.851-3.282).
Conclusions:
The CSHA Frailty Scale was not independently associated with readmission in the setting of PCI in our health system. This particular assessment of frailty may not provide added value over traditional comorbidities in this patient population.
