Abstract

Background: Safe hospital discharge on parenteral antibiotic therapy is challenging for people who inject drugs (PWID) admitted with serious bacterial infections (SBI). We describe a Comprehensive Care of Drug Addiction and Infection (CCDAI) program involving a partnership between Intermountain Healthcare hospitals and a detoxification facility (DF) to provide simultaneous drug recovery assistance and parenteral antibiotic therapy (DRA-OPAT).

Methods: The CCDAI program was evaluated using a pre-/poststudy design. We compared outcomes in PWID hospitalized with SBI during a 1-year postimplementation period (2018) with similar patients from a historical control period (2017), identified by propensity modeling and manual review.

Results: Eighty-seven patients were candidates for the CCDAI program in the implementation period. Thirty-five participants (40.2%) enrolled in DRA-OPAT and discharged to the DF; 16 (45.7%) completed the full outpatient parenteral antibiotic therapy (OPAT) duration. Fifty-one patients with similar characteristics were identified as a preimplementation control group. Median length of stay (LOS) was reduced from 22.9 days (interquartile interval [IQI], 9.8-42.7) to 10.6 days (IQI, 6-17.4) after program implementation (P < .0001). Total median cost decreased from $39 220.90 (IQI, $23 300.71-$82 506.66) preimplementation to $27 592.39 (IQI, $18 509.45-$48 369.11) postimplementation (P < .0001). Ninety-day readmission rates were similar (23.5% vs 24.1%; P = .8). At 1-year follow-up, all-cause mortality was 7.1% in the preimplementation group versus 1.2% postimplementation (P = .06).

Conclusions: Partnerships between hospitals and community resources hold promise for providing resource-efficient OPAT and drug recovery assistance. We observed significant reductions in LOS and cost without increases in readmission rates; 1-year mortality may have been improved. Further study is needed to optimize benefits of the program.
