Care pathway reduces hospitalizations and cost for hemodialysis vascular access surgery

Hemodialysis vascular access-related hospitalizations account for more than 20% of United States end-stage renal disease (ESRD) hospitalizations, with an annual cost approximating $675 million. Limiting access-related costs while delivering similar degrees of quality care thus would enhance alternative utilization of ESRD funding. We implemented a vascular access care pathway emphasizing coordinated patient evaluation and outpatient surgery to determine whether such an intervention affected outcomes associated with vascular access surgery. Data examining hospitalization and vascular access surgery charges, complications, and patient satisfaction (determined by questionnaire) were analyzed, comparing patients who underwent vascular access surgery in 1994 and 1995 as inpatients (non-care pathway patients) and patients who underwent vascular access surgery via the care pathway in 1995. Inpatient days declined in 1995 (1994: 582 days; 1995: 85 days; P < 0.03) and the average charges per patient for the care pathway cohort were significantly less than charges per patient in 1994 and charges for non-care pathway patients in 1995 (1994 patients: $10,524 +/- $5,209; 1995 non-care pathway patients: $11,196 +/- $5,806; 1995 care pathway patients: $4,686 +/- $2,912/patient; P < 0.02). Incidence rates for major (life-threatening) complications were not significantly different between 1994 patients and care pathway patients in 1995. However, the 1995 non-care pathway patients had a higher incidence of major complications (15.4%). Forty-seven repeat access procedures were performed in 29 patients in 1994 versus 35 repeat access procedures in 22 care pathway patients in 1995, and 12 repeat access procedures were performed in eight non-care pathway patients in 1995. Finally, a majority of the patients entered into the care pathway who responded to a survey stated that they were satisfied with access surgery via the care pathway. These data suggest that a vascular access care pathway can reduce hospital days and costs while achieving acceptable outcomes for access surgery.
