A Novel Program to Provide Drug Recovery Assistance and Outpatient Parenteral Antibiotic Therapy in People Who Inject Drugs
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-post study design. We compared outcomes in PWID hospitalized with SBI during a 1-year post-implementation 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. 35 participants (40.2%) enrolled in DRA-OPAT and discharged to the DF; 16 (45.7%) completed the full OPAT duration. Fifty-one patients with similar characteristics were identified as a pre-implementation control group. Median length of stay (LOS) was reduced from 22.9 days (IQI 9.8-42.7) to 10.6 days (IQI 6-17.4) after program implementation, p<0.0001. Total median cost decreased from $39,220.90 (IQI $23,300.71-$82,506.66) pre-implementation vs $27,592.39 (IQI $18,509.45-48,369.11) post-implementation, p<0.0001. 90-day readmission rates were similar (23.5% vs 24.1%), p=0.8. At 1-year follow-up, all-cause mortality was 7.1% in the pre-implementation group vs 1.2% post-implementation, p=0.06. Conclusion Partnerships between hospitals and community resources hold promise for providing resource efficient OPAT and drug recovery assistance. We observed significant reductions in length of stay and cost without increases in readmission rates; 1-year mortality may have been improved. Further study is needed to optimize benefits of the program.
