Improving ambulatory infusion drug delivery through alarm management using a quality improvement model and team learning.

Abstract

472 Background: A quality outpatient cancer program depends on the accurate delivery of chemotherapy using a computerized ambulatory infusion pump to deliver a therapeutic dose of chemotherapy for patients. Between April and July 2021, our cancer center hotline reported an excessive rate of 60% of ambulatory pump were generating alarms. This resulted in interruptions in dose delivery, disruptions in clinical workflows, and negatively impacted patient satisfaction. Methods: A multidisciplinary team of frontline nurses, pharmacists, nurse leaders, and quality specialists was assembled to analyze six months of alarm data using a plan-do-study-act (PDSA) model. Quality tools were utilized to determine the root cause of the alarms and arrive at solutions to improve drug delivery by reducing alarms and calls to the infusion hotline. The team discovered 49% (n=22/45) of alarm could not be resolved, resulting in a dose interruption of the planned chemotherapy infusions. Patients returned to the infusion suite without receiving the total dose of chemotherapy as ordered. A full 70% of the hotline calls (n=16/22) were due to a “No Disposable” alarm code. Analysis of these returned units by both our group and the vendor led us to recommend a more advanced replacement model which was implemented in June/July of 2022. Results: Between July and December 2022, MCI outpatient ambulatory pump medication variances related to “No Disposable” improved by 100%. A total of 34 calls were received by the Hotline Nurse with 91% (31/34) of calls were successfully resolved. None of the ambulatory patients experienced an interruption in chemotherapy drug delivery. Conclusions: Forming a multidisciplinary working group resulted in a timely and significant improvement in chemotherapy safety using the PDSA model of quality improvement. Most importantly, confidence in chemotherapy drug delivery using ambulatory infusion pump was expressed by infusion nurses, pharmacists, and medical providers.
