Background:
Infections are a significant source of morbidity/mortality in allogeneic stem cell transplant (alloSCT) patients and antimicrobial prophylaxis has reduced deaths. Between July 2022 and July 2023, 21% of new alloSCT recipients were discharged from UVA Medical Center without posaconazole or isavuconazonium +/- letermovir in-hand at the time of hospital discharge necessitating daily oral drug administration at the infusion center until medication could be obtained. This led to excess cost for UVA, burden on clinic staff, missed doses, and patient frustration. We sought to decrease the number of new alloSCT recipients discharged without appropriate prophylaxis in-hand from 21% to 10% by November 2024.
Methods:
Per the 2023 ASCO Quality Training Program associated with this project, a Model for Improvement and Plan Do Study Act (PDSA) methodology was utilized. The population included alloSCT patients with new prescriptions (Rxs) for posaconazole or isavuconazonium +/- letermovir. The outcome measure was percentage of newly discharged alloSCT patients requiring oral prophylaxis at the infusion center. The process measure was Time to Affordable Medication (TAM) defined as days from Rx prior-authorization (PA) request to paid claim with an affordable copay (defined as a copay the patient was able/willing to pay, including free drug approvals or assistance programs). The counter measure consisted of initiating the Rx PA process 10 days prior to planned admission via a discharge test Rx order set instead of waiting until admission. This standardized process allowed for clearer communication and more time for pharmacy technicians to process the Rx for PA, copays, free drug applications, and pharmacy logistics. Upon admission, the official Rx was released to the discharge pharmacy. If Rx shipment was required, this was set up the week prior to discharge. An I-chart (3-sigma) statistical process control (SPC) chart was used to assess the intervention.
Results:
The baseline TAM was assessed retrospectively in 22 Rxs over 3 months prior to intervention for a mean of 7.5 days. PDSA cycle 1 was implemented Nov. 2023. TAM for the first 35 Rxs was 4.3 days and the SPC upper control limit decreased from 26.3 days to 13.3 days demonstrating overall markedly decreased variation despite data from early 2024 having greater variability due to new insurance deductibles. Rxs requiring 10 or more days were due to free drug application processes. Importantly, no newly discharged alloSCT patients have required drug administration at the infusion center.
Conclusions:
PDSA #1 resulted in a decrease in TAM of 3.2 days, decreased variation in the process, and no patients discharged without drug in hand. Since we have already surpassed our aim, next steps include demonstrating sustainability of the process and a survey requesting feedback to identify balance measures.
