Apheresis platelet collections at a hospital-based donor center.

<p>Graph shows an 89-month analysis of apheresis platelet collections separated into four phases. (a) Growth-phase 1: Initial growth-phase prior to saturation; (b) Plateau-phase: period of no growth coinciding with schedule saturation; (c) Growth-phase 2: period of growth in collections secondary to interventions: #1—acquiring a second apheresis unit and #2—increasing donor collection days; (d) Donor recruitment-phase: transient surge in platelet collections secondary to interventions #3—scripted phone calls and #4—posting of donor recruitment flyers. The dotted line denotes the maximum scheduling capacity. Avg. sch. = Average Scheduling.
