Predictors for Nonhome Patient Discharge following Lower Extremity Arterial Interventions

Purpose: To identify the variables associated with patient discharge disposition to optimize postprocedural care and discharge planning following lower extremity arterial interventions for peripheral artery disease (PAD). Materials and Methods: The 2014-2017 American College of Surgeons National Surgical Quality Improvement Program database was queried using current procedural terminology codes for endovascular infrainguinal interventions for PAD. The main outcome variable of interest was nonhome discharge. Covariates included patient sociodemographic variables, age quartile (upper quartile, >= 77 years), comorbidities (diabetes, renal disease, bleeding disorder, congestive heart failure [CHF], and chronic obstructive pulmonary disease), presence of an open wound before a procedure, type of procedure, operative time, symptom severity, American Society of Anesthesiologists class, and baseline functional status. Univariate analysis and multivariate logistic regression were performed on Stata/SE 15.1. Results: A total of 3,190 patients met the inclusion criteria, of whom 664 (20.8%) had nonhome discharge. Multivariate regression revealed that age (odds ratio [OR], 1.9 for the upper age quartile [>77 years]; 95% confidence interval [CI], 1.46-2.50), operative time (OR, 1.2 per increase in quartile; 95% CI, 1.09-1.30), preoperative wound (OR, 1.5; 95% CI, 1.24-1.90), renal failure (OR, 1.7; 95% CI, 1.30-2.14), CHF (OR, 2.2; 95% CI, 1.51-3.24), symptom severity (OR, 1.7; 95% CI, 1.46-1.98), and independent functional status (OR, 0.74; 95% CI, 0.59-0.92; P =.007) were associated with nonhome discharge. All P values were <=.001 unless otherwise stated. Conclusions: Prolonged procedural time, the presence of preprocedural wound and patient comorbidities, symptomatology, and baseline functional status may be used to identify patients who will require a nonhome discharge and early discharge planning.

Automated summary

The purpose of this study was to identify variables associated with patient discharge disposition following lower extremity arterial interventions for peripheral artery disease. The study found that prolonged procedural time, the presence of preprocedural wound, patient comorbidities, symptom severity, and baseline functional status were associated with nonhome discharge.
