Development of a Primary Care Transitions Clinic in an Academic Medical Center.

INTRODUCTION: Transitions of care experiences leave patients vulnerable to adverse outcomes, including readmissions, worsening symptoms, and reductions in functional status. AIM: To describe and evaluate a primary care transitions clinic that serves patients with medical and/or social needs that must be addressed prior to establishment of primary care. SETTING: Brigham Health, an academic medical center in Boston, MA. PROGRAM DESCRIPTION: The transitions clinic opened within an existing primary care practice in January 2019. It employs one full-time nurse care coordinator and one full-time medical assistant, and is staffed by one primary care physician (PCP) or nurse practitioner each weekday afternoon. Both medical and social diagnoses that require follow-up post-discharge are addressed. Patients with any insurance are seen as many times as necessary until PCP care is established. PROGRAM EVALUATION: In the year after its establishment (January 20, 2019, to January 19, 2020), the transitions clinic received 498 referrals (73.2% from the emergency department (ED), 23.3% from inpatient), with 207 patients ultimately seen. Patients were seen 5 (median; IQR 4-6) work days post-discharge, with 2 (median; IQR 1-3) visits per patient. Patients seen in the transitions clinic had significantly fewer ED visits than a comparator cohort referred to Brigham Health Primary Care after ED or hospital discharge in the year prior (January 20, 2018, to January 20, 2019). Patients seen in the transitions clinic additionally had significantly fewer ED visits and hospitalizations in the three months post-referral than in the three months pre-referral. The most common social determinants addressed by the clinic's nurse coordinator were insurance, transportation, and housing. DISCUSSION: A primary care transitions clinic can provide accessible, attentive care post-discharge with positive effects on healthcare utilization. Availability of a multidisciplinary team that can see patients for repeated visits until establishment of PCP care was a key success factor for the transitions clinic.

Mobile Health Services for COVID-19: Counseling, Testing, and Vaccination for Medically Underserved Populations.

Mobile health units can improve access to preventive health services, especially for medically underserved populations. However, there is little published experience of mobile health units being used to expand access to COVID-19 vaccination. In concert with local public health departments and community members, we implemented a mobile COVID-19 health unit and deployed it to 12 predominantly low-income and racial/ethnic minority communities in Massachusetts. We describe the success and challenges of this innovative program in expanding access to COVID-19 vaccination. (Am J Public Health. 2022;112(11):1556-1559. https://doi.org/10.2105/AJPH.2022.307021).

Expanding COVID-19 vaccine access to underserved populations through implementation of mobile vaccination units.

COVID-19 has disproportionately impacted underserved populations, including racial/ethnic minorities. Prior studies have demonstrated that mobile health units are effective at expanding preventive services for hard-to-reach populations, but this has not been studied in the context of COVID-19 vaccination. Our objective was to determine if voluntary participants who access mobile COVID-19 vaccination units are more likely to be racial/ethnic minorities and adolescents compared with the general vaccinated population. We conducted a cross-sectional study of individuals who presented to three different mobile COVID-19 vaccination units in the Greater Boston area from May 20, 2021, to August 18, 2021. We acquired data regarding the general vaccinated population in the state and of target communities from the Massachusetts Department of Public Health. We used chi-square testing to compare the demographic characteristics of mobile vaccination unit participants and the general state and community populations that received COVID-19 vaccines during the same time period. We found that during this three-month period, mobile vaccination units held 130 sessions and administered 2622 COVID-19 vaccine doses to 1982 unique participants. The median (IQR) age of participants was 31 (16-46) years, 1016 (51%) were female, 1575 (80%) were non-White, and 1126 (57%) were Hispanic. Participants in the mobile vaccination units were more likely to be younger (p < 0.001), non-White race (p < 0.001), and Hispanic ethnicity (p < 0.001) compared with the general vaccinated population of the state and target communities. This study suggests that mobile vaccination units have the potential to improve access to COVID-19 vaccination for diverse populations.

Feasibility and Safety of Outpatient Parenteral Antimicrobial Therapy in Conjunction With Addiction Treatment for People Who Inject Drugs.

BACKGROUND: Research is limited on combining outpatient parenteral antimicrobial therapy (OPAT) with addiction treatment for people who inject drugs (PWID) with serious infections. METHODS: This is a retrospective study of PWID (n = 68) requiring intravenous antibiotics evaluated for suitability for our OPAT program with concurrent addiction treatment. RESULTS: Most common infections were bacteremia and/or endocarditis (73.5%), bone and/or joint infections (32.4%), and epidural abscess (22.1%). Of the 20 patients (29.4%) who qualified, 100.0% completed the course of antibiotics, 30.0% experienced a 30-day readmission, and 15.0% relapsed. No overdoses, deaths, or peripherally inserted central catheter-line complications were reported. CONCLUSIONS: Outpatient parenteral antimicrobial therapy with addiction treatment may be feasible and safe for PWID with serious infections.

Disparities in United States hospitalizations for serious infections in patients with and without opioid use disorder: A nationwide observational study.

BACKGROUND: Patients with opioid use disorder (OUD) who are hospitalized for serious infections requiring prolonged intravenous antibiotics may face barriers to discharge, which could prolong hospital length of stay (LOS) and increase financial burden. We investigated differences in LOS, discharge disposition, and charges between hospitalizations for serious infections in patients with and without OUD. METHODS AND FINDINGS: We utilized the 2016 National Inpatient Sample-a nationally representative database of all discharges from US acute care hospitals. The population of interest was all hospitalizations for infective endocarditis, epidural abscess, septic arthritis, or osteomyelitis. The exposure was OUD, and the primary outcome was LOS until discharge, assessed by using a competing risks analysis to estimate adjusted hazard ratios (aHRs). Adjusted odds ratio (aOR) of discharge disposition and adjusted differences in hospital charges were also reported. Of 95,470 estimated hospitalizations for serious infections (infective endocarditis, epidural abscess, septic arthritis, and osteomyelitis), the mean age was 49 years and 35% were female. 46% had Medicare (government-based insurance coverage for people age 65+ years), and 70% were non-Hispanic white. After adjustment for potential confounders, OUD was associated with a lower probability of discharge at any given LOS (aHR 0.61; 95% CI 0.59-0.63; p < 0.001). OUD was also associated with lower odds of discharge to home (aOR 0.38; 95% CI 0.33-0.43; p < 0.001) and higher odds of discharge to a post-acute care facility (aOR 1.85; 95% CI 1.57-2.17; p < 0.001) or patient-directed discharge (also referred to as "discharge against medical advice") (aOR 3.47; 95% CI 2.80-4.29; p < 0.001). There was no significant difference in average total hospital charges, though daily hospital charges were significantly lower for patients with OUD. Limitations include the potential for unmeasured confounders and the use of billing codes to identify cohorts. CONCLUSIONS: Our findings suggest that among hospitalizations for some serious infections, those involving patients with OUD were associated with longer LOS, higher odds of discharge to post-acute care facilities or patient-directed discharge, and similar total hospital charges, despite lower daily charges. These findings highlight opportunities to improve care for patients with OUD hospitalized with serious infections, and to reduce the growing associated costs.

Impact of Medications for Opioid Use Disorder on Discharge Against Medical Advice Among People Who Inject Drugs Hospitalized for Infective Endocarditis.

BACKGROUND AND OBJECTIVES: The impact of medications for opioid use disorder (MOUD) on against medical advice (AMA) discharges among people who inject drugs (PWID) hospitalized for endocarditis is unknown. METHODS: A retrospective review of all PWID hospitalized for endocarditis at our institution between 2016 and 2018 (n = 84). RESULTS: PWID engaged with MOUD at admission, compared with those who were not, were less likely to be discharged AMA but this did not reach statistical significance in adjusted analysis (odds ratio [OR], 0.22; 95% confidence interval [CI], 0.033-1.41; P = .11). Among out-of-treatment individuals, newly initiating MOUD did not lead to significantly fewer AMA discharges (OR, 0.98; 95% CI, 0.26-3.7; P = .98). CONCLUSION AND SCIENTIFIC SIGNIFICANCE: PWID hospitalized for endocarditis are at high risk for discharge AMA but more research is needed to understand the impact of MOUD.

A Health System-Wide Initiative to Decrease Opioid-Related Morbidity and Mortality.

BACKGROUND: The opioid overdose crisis now claims more than 40,000 lives in the United States every year, and many hospitals and health systems are responding with opioid-related initiatives, but how best to coordinate hospital or health system-wide strategy and approach remains a challenge. METHODS: An organizational opioid stewardship program (OSP) was created to reduce opioid-related morbidity and mortality in order to provide an efficient, comprehensive, multidisciplinary approach to address the epidemic in one health system. An executive committee of hospital leaders was convened to empower and launch the program. To measure progress, metrics related to care of patients on opioids and those with opioid use disorder (OUD) were evaluated. RESULTS: The OSP created a holistic, health system-wide program that addressed opioid prescribing, treatment of OUD, education, and information technology tools. After implementation, the number of opioid prescriptions decreased (-73.5/month; p < 0.001), mean morphine milligram equivalents (MME) per prescription decreased (-0.4/month; p < 0.001), the number of unique patients receiving an opioid decreased (-52.6/month; p < 0.001), and the number of prescriptions ≥ 90 MME decreased (-48.1/month; p < 0.001). Prescriptions and providers for buprenorphine increased (+6.0 prescriptions/month and +0.4 providers/month; both p < 0.001). Visits for opioid overdose did not change (-0.2 overdoses/month; p = 0.29). CONCLUSION: This paper describes a framework for a new health system-wide OSP. Successful implementation required strong executive sponsorship, ensuring that the program is not housed in any one clinical department in the health system, creating an environment that empowers cross-disciplinary collaboration and inclusion, as well as the development of measures to guide efforts.

Home Intravenous Antibiotic Treatment for a Patient with Opioid Use Disorder.

Intravenous drug abusers may incur bloodstream infections, in particular those involving the heart valves, that often require extended courses of antibiotics, commonly on the order of six weeks. Conventional wisdom has dictated that even when patients are sufficiently well to not need ongoing hospitalization, it is unsafe to complete their antibiotic course in any setting other than in a closely supervised facility, even if this is contrary to their wishes. The assumption has been that such patients would be at risk of using their indwelling intravenous catheter for illicit purposes. Recent advances in the care of patients who suffer from addiction disorders suggest that when patients receive state-of-the-art addiction treatment, many may be able to continue their intravenous antibiotic course unsupervised, at home. This represents a departure from the parentalistic model of care of impaired patients who are prone to self-harm, moving towards a model that respects autonomy and trusts patients who are in recovery to continue their care in a manner that is self-beneficial.

Long-term Outcomes of Injection Drug-related Infective Endocarditis Among People Who Inject Drugs.

OBJECTIVES: Infective endocarditis (IE) among people who inject drugs is associated with high rates of mortality and repeat episodes of endocarditis. We sought to report on longer-term clinical outcomes of patients with IE who were offered buprenorphine or methadone treatment for opioid use disorder (OUD) at their initial hospital admission. METHODS: Individuals with OUD hospitalized between 2013 and 2015 with IE were included for the retrospective study. The following data were extracted from the medical record: sociodemographic data, mortality, repeat episodes of endocarditis, and evidence of ongoing buprenorphine and methadone treatment. The impact of medication use on mortality and repeat episode of endocarditis was examined using survival analysis. RESULTS: Overall, 26 individuals were included in the study. The mean duration of follow-up was 45.0 months (SD 7.2, range 34.0-56.0). During the index admission, 8 received buprenorphine, 8 received methadone, and 10 declined medications. During the follow-up period, 4 (15.4%) individuals died and 10 (38.5%) individuals experienced a repeat episode of endocarditis. Survival analysis of mortality (log-rank P = 0.066) and repeat episode of endocarditis (log-rank P = 0.86) comparing those who received buprenorphine, received methadone, and declined medication did not differ significantly. CONCLUSIONS: Initiation of medication treatment alone may not be sufficient to impact long-term mortality and rates of repeat episode of endocarditis. More research is needed to identify optimal treatment strategies for people who inject drugs with IE.

Outpatient Parenteral Antimicrobial Therapy Among People Who Inject Drugs: A Review of the Literature.

Hospitalizations for people who inject drugs (PWID) with infectious complications requiring prolonged antibiotic therapy are increasing in the context of the opioid epidemic. Although outpatient parenteral antimicrobial therapy (OPAT) is routinely offered to patients without a history of injection drug use (IDU), PWID are often excluded from consideration of OPAT. To better assess the evidence base for the safety and effectiveness of OPAT for PWID, we conducted a review of the published literature. Results suggest that OPAT may be safe and effective for PWID, with rates of OPAT completion, mortality, and catheter-related complications comparable to rates among patients without a history of IDU. Rates of hospital readmissions may be higher among PWID, but instances of misuse of the venous catheter were rarely reported. More research is needed to study the safety and effectiveness of OPAT among PWID, as well as studying the combination of OPAT and addiction treatment.

ED-based care coordination reduces costs for frequent ED users.

OBJECTIVES: We evaluated a pilot quality improvement intervention implemented in an urban academic medical center emergency department (ED) to improve care coordination and reduce ED visits and hospitalizations among frequent ED users. STUDY DESIGN: Randomized controlled trial. METHODS: We identified the most frequent ED users in both the 30 days prior to the intervention and the 12 months prior to the intervention. We randomized the top 72 patients to receive either our pilot intervention or usual care. The intervention consisted of a community health worker who assisted patients with navigating care and identifying unmet social needs and an ED-based clinical team that developed interdisciplinary acute care plans for eligible patients. After 7 months, we analyzed ED visits, hospitalizations, and costs for the intervention and control groups. RESULTS: We randomized 72 patients to the intervention (n = 36) and control (n = 36) groups. Patients randomized to the intervention group had 35% fewer ED visits (P = .10) and 31% fewer admissions from the ED (P = .20) compared with the control group. Average ED direct costs per patient were 15% lower and average inpatient direct costs per patient were 8% lower for intervention patients compared with control patients. CONCLUSIONS: ED-based care coordination is a promising approach to reduce ED use and hospitalizations among frequent ED users. Our program also demonstrated a decrease in costs per patient. Future efforts to promote population health and control costs may benefit from incorporating similar programs into acute care delivery systems.

Conflicting effects of atazanavir therapy on atherosclerotic risk factors in stable HIV patients: A randomized trial of regimen switch to atazanavir.

Bilirubin acts as a potent endogenous antioxidant, with higher concentrations associated with lower rates of CVD; the antiretroviral drug atazanavir (ATV) increases bilirubin levels but may also increase von Willebrand factor levels. We tested the hypothesis that increasing endogenous bilirubin using ATV would improve cardiometabolic risk factors and vascular function in older patients with HIV. Ninety participants were enrolled in two study protocols. In protocol 1, we evaluated markers of inflammation, thrombosis, and conduit artery endothelial function in subjects on non-ATV containing regimens. Participants were randomly assigned to continue baseline treatment or switch to an ATV-based regimen. Measurements were made at baseline and 28 days. In the protocol 2, we enrolled 30 subjects who received atazanavir for more than one year and were compared to the aim 1 protocol subjects at baseline. 60 subjects were enrolled in the first protocol (mean age 53, +/- 6 years), with 31 randomized to ATV and 29 continuing baseline treatment. Atazanavir significantly increased serum total bilirubin levels (p<0.001) and acutely but not chronically plasma total antioxidant capacity (p<0.001). An increase in von Willebrand Factor (p<0.001) and reduction in hs-CRP (p = 0.034) were noted. No changes were seen in either flow-mediated endothelium-dependent or vasodilation. In cross-sectional analysis (second protocol), similar findings were seen in the baseline attributes of non-atazanavir-based and long-term atazanavir users. Increasing serum bilirubin levels with atazanavir in subjects with HIV reduces hs-CRP, temporarily reduces oxidative stress, but increases von Willebrand Factor. Atazanavir does not improve endothelial function of conduit arteries. TRIAL REGISTRATION: ClinicalTrials.gov NCT03019783.
