Low Use of Outpatient Parenteral Antimicrobial Therapy for Drug Use-Associated Infective Endocarditis in an Urban Hospital System

PICC Your Poison: Resident Beliefs and Attitudes Regarding Discharge Parenteral Antibiotics for Patients Who Inject Drugs

Background

Serious injection-related infections (SIRIs) in people who inject drugs often lead to prolonged hospitalizations or premature discharges. This may be in part due to provider reluctance to place peripherally inserted central catheters (PICCs) for outpatient parenteral antibiotic therapy in this population. Because internal medicine (IM) residents are often frontline providers in academic centers, understanding their perspectives on SIRI care is important to improve outcomes.

Methods

We surveyed IM residents in a large urban multicenter hospital system about SIRI care with a novel case-based survey that elicited preferences, comfort, experience, and stigma. The survey was developed using expert review, cognitive interviewing, and pilot testing. Results are reported with descriptive statistics and linear regression.

Results

Of 116 respondents (response rate 34%), most (73%) were uncomfortable discharging a patient with active substance use home with a PICC, but comfortable (87%) with discharge to postacute facilities. Many (∼40%) endorsed high levels of concern for PICC misuse or secondary line infections, but larger numbers cited concerns about home environment (50%) or loss to follow-up (68%). While overall rates were low, higher stigma was associated with more concerns around PICC use (r = -0.3, P = .002). A majority (58%) believed hospital policies against PICC use in SIRI may act as a barrier to discharge, and 74% felt initiation of medications for opioid use disorder (MOUD) would increase their comfort discharging with a PICC.

Conclusions

Most IM residents endorsed high levels of concern about PICC use for SIRI, related to patient outcomes and perceived institutional barriers, but identified MOUD as a mitigating factor.

Perspectives on the Use of Outpatient Parenteral Antibiotic Therapy for People who Inject Drugs: Results From an Online Survey of Infectious Diseases Clinicians

Injection-related infections require prolonged antibiotic therapy. Outpatient parenteral antimicrobial therapy (OPAT) has been shown to be feasible for people who inject drugs (PWID) in some settings. We report a national survey on practice patterns and attitudes of infectious diseases clinicians in the United States regarding use of OPAT for PWID.

"They Just Assume That We're All Going to Do the Wrong Thing With It. It's Just Not True": Stakeholder Perspectives About Peripherally Inserted Central Catheters in People Who Inject Drugs

Background

In the absence of adequate harm reduction opportunities, people who inject drugs (PWID) are at increased risk for serious infections. Infectious diseases guidelines recommend extended periods of intravenous antibiotic treatment through peripherally inserted central catheters (PICCs), but PWID are often deemed unsuitable for this treatment. We conducted semi-structured interviews and focus groups to understand the perspectives and opinions of patients and clinicians on the use of PICCs for PWID.

Methods

We approached patients and clinicians (doctors, nurses, PICC nurses, social workers, and case workers) involved in patient care at Tufts Medical Center (Boston, Massachusetts) between August 2019 and April 2020 for semi-structured interviews and focus groups.

Results

Eleven of 14 (79%) patients agreed to participate in an in-depth interview, and 5 role-specific clinician focus groups (1 group consisting of infectious diseases, internal medicine, and addiction psychiatry doctors, 2 separate groups of floor nurses, 1 group of PICC nurses, and 1 group of social workers) were completed. Emergent themes included the overall agreement that PICCs improve healthcare, patients' feelings that their stage of recovery from addiction was not taken into consideration, and clinicians' anecdotal negative experiences driving decisions on PICCs.

Conclusions

When analyzed together, the experiences of PWID and clinicians shed light on ways the healthcare system can improve the quality of care for PWID hospitalized for infections. Further research is needed to develop a system of person-centered care for PWID that meets the specific needs of patients and improves the relationship between them and the healthcare system.

Can I Safely Discharge a Patient with a Substance Use Disorder Home with a Peripherally Inserted Central Catheter?

Discharging Patients Who Use Drugs Home with PICCAmid the U.S. overdose crisis, serious injection-related infections are rising. Determining where a patient goes after hospitalization can be a challenge due to the need for prolonged parenteral antibiotics, prompting a common clinical question: Can I safely discharge a patient with a substance use disorder home with a peripherally inserted central catheter?

Patient-Directed Discharges Among Persons Who Use Drugs Hospitalized with Invasive Staphylococcus aureus Infections: Opportunities for Improvement

BACKGROUND

Despite the high burden of Staphylococcus aureus infections among persons who use drugs, limited data exist comparing outcomes of patient-directed discharge (known as discharge against medical advice) compared with standard discharge among persons who use drugs hospitalized with S. aureus infection.

METHODS

We conducted a retrospective study of hospitalizations among adults with S. aureus bacteremia, endocarditis, epidural abscess, or vertebral osteomyelitis at 2 San Francisco hospitals between 2013 and 2018. We compared odds of 1-year readmission for infection persistence or recurrence and 1-year mortality via multivariable logistic regression models adjusting for age, sex, Charlson comorbidity index, and homelessness.

RESULTS

Overall, 80 of 340 (24%) of hospitalizations for invasive S. aureus infections among persons who use drugs involved patient-directed discharge. More than half of patient-directed discharges 41 of 80 (51%) required readmission for persistent or recurrent S. aureus infection compared with 54 of 260 (21%) patients without patient-directed discharge (adjusted odds ratio 3.8, 95% confidence interval [CI] 2.2-6.7). One-year cumulative mortality was 15% after patient-directed discharge compared with 11% after standard discharge (P = .02); however, this difference was not significant after adjustment for mortality risk factors. More than half of deaths in the patient-directed discharge group (7 of 12, 58%) were due to drug overdose; none was due to S. aureus infection.

CONCLUSIONS

Among persons who use drugs hospitalized with invasive S. aureus infection, odds of hospital readmission for infection were almost 4-fold higher following patient-directed discharge compared with standard discharge. All-cause 1-year mortality was similarly high in both groups, and drug overdose was a common cause of death in patient-directed discharge group.
