Capacity Prioritization Initiative Reduced the Wait Time for Port Placement and Facilitated Increased Volume of Port Placements at a Large County Health System.

DESCRIPTION OF THE PROBLEM: Wait time from request to placement of ports in interventional radiology had increased from 14 to 27 days over a 4-month period. The goal of this project was to reduce the wait time by 15% within 4 months while accommodating additional volume. INSTITUIONAL APPROACH TO ADDRESS PROBLEM: Capacity analysis revealed 2 bottlenecks: (1) inadequate provider capacity for preprocedural visits in interventional radiology clinic and (2) inadequate number of spots for port placement in the angiography schedule. The intervention consisted of: (1) 2 reserved slots in the attending physician's morning clinic schedule and (2) 3 daily guaranteed spots for port placement in the angiography suite. Both changes were integrated into the electronic medical record scheduling system. DESCRIPTION OF OUTCOMES: After the intervention, per biweekly period, the number of port requests increased by 17% (Preintervention: 16.6 ± 3.1, Postintervention: 20.1 ± 4.1, P = 0.03), the number of completed clinic visits increased by 19% (Preintervention: 16.7 ± 5.1, Postintervention: 20.5 ± 3.6, P = 0.05), and the number of port placements increased by 19% (Preintervention: 16.9 ± 3.9, Postintervention: 21.0 ± 3.5, P = 0.02). The average wait time from request to placement decreased by 22% (Preintervention: 22.2 ± 4.4 days, Postintervention: 18.3 ± 3.4 days, P = 0.03), driven by a 49% decrease in wait time between request and clinic visit (Preintervention: 11.0 ± 2.3 days, Postintervention: 7.4 ± 1.0 days, P = 0.03). CONCLUSIONS: Prioritization of clinic and angiography suite capacity, integrated into the electronic scheduling system, significantly reduced the wait time for port placement, even with significant increases in the volume of port requests.
