Poster presents efficacy data on 12 months of median daily dosing and 957 refill procedures. Improvements from baseline efficacy was experienced by >61% of patients completing 6 months of follow-up questionnaires, and >66% of subjects completing 12 months of questionnaires. Accuracy is shown to be 97.3% ±0.4%. Accuracy data was determined to be independent of flow rate. Poster concluded that the Prometra offers the potential for improved patient outcomes through the reduced risk of under or over dosing by providing highly accurate deliver of drug. Additional benefits include the ability to program zero flow, sustain accuracy at low pump volumes, and reduce sensitivity to environmental temperature and pressure.
