Evaluation of physicians prescribing of COVID-19 guideline-directed outpatient treatments in a primary care walk-in clinic.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is a respiratory virus that has afflicted millions of individuals in the United States. A few medications have been determined to be beneficial for outpatient treatment. The medications in use against mild-to-moderate COVID-19 in the outpatient setting during the study period are nirmatrelvir-ritonavir, remdesivir, molnupiravir, and bebtelovimab. Proper assessment and treatment of patients with mild-to-moderate COVID-19 in the outpatient setting is critical to reducing rates of disease progression and hospitalization. OBJECTIVE: This study aimed to evaluate the appropriateness of the prescribing by internal medicine physicians for mild-to-moderate Coronavirus disease 2019 (COVID-19) infections based on the National Institutes of Health (NIH) guideline-directed COVID-19 outpatient treatment options. METHODS: This is a retrospective chart review examining the outpatient treatment of mild-to-moderate COVID-19 by internal medicine physicians between February 2022 and August 2022. Patients were eligible if they were 18 years or older, had a positive home or polymerase chain reaction (PCR) test, completed a telehealth visit within 7 days of the positive test, and were prescribed either nirmatrelvir-ritonavir, remdesivir, molnupiravir, or bebtelovimab for COVID-19 treatment. The primary end point was the appropriateness of COVID-19 treatment in the outpatient setting based on NIH guidelines, patient characteristics, and prescribing information for the medications. The secondary end point was hospitalization within 30 days of initiation of outpatient COVID-19 treatment. The presence or absence of a clinical pharmacist consultation at the time of prescribing was recorded as a process measure. RESULTS: A total of 376 encounters were assessed, of which 226 were included and analyzed. A total of 210 participants (93%) received nirmatrelvir-ritonavir. The remaining participants received molnupiravir or bebtelovimab. Overall, guideline-concordant treatment for mild-to-moderate COVID-19 was prescribed for 200 participants (88%). Among patient characteristics, only glomerular filtration rate (GFR) had a statistically significant difference between groups prescribed medication for the treatment of mild-to-moderate COVID-19. Fifty-six participants (25%) received clinical pharmacist consultation. Three participants were hospitalized for COVID-19 within 30 days of receiving an appropriately prescribed medication for treatment. Nirmatrelvir-ritonavir was the only medication potentially prescribed inappropriately due to lack of being renally dose adjusted and the extensive drug-drug interactions. CONCLUSION: Nirmatrelvir-ritonavir was the most prescribed medication for the treatment of mild-to-moderate COVID-19, consistent with its position as first-line therapy and widespread accessibility. The study results will inform future educational opportunities, such as in-service presentations and handouts, that may improve the prescribing of outpatient treatment for mild-to-moderate COVID-19 moving forward.

Community pharmacists and communication in the time of COVID-19: Applying the health belief model.

The emergence of the novel coronavirus disease (COVID-19) pandemic presents an unprecedented health communications challenge. Healthcare providers should reinforce behaviors that limit the spread of the pandemic, including social distancing and remaining in the home whenever possible. Formal communications toolkits may not be prepared in a timely fashion. Community pharmacists can reinforce mitigation behaviors by applying the health belief model (HBM). This commentary provides an overview of the HBM and offers suggestions on how community pharmacists can use it as a guide to patient communication in these uncertain contexts.

Syringe services programs and real-world research: An overview for pharmacists.

OBJECTIVE: To review key arguments supporting and criticizing syringe services programs (SSPs). DATA SOURCES: Peer-reviewed literature and publicly available documents. SUMMARY: Pharmacy organizations-including the American Pharmacists Association and the American Society of Health-System Pharmacists-have stated that pharmacists should support programs that supply sterile injection materials to persons who use injection drugs. SSPs may include needle exchanges or other programs that meet these aims. Pharmacists should know that observational public health research demonstrates that SSPs can lower the transmission of blood-borne illnesses, improve linkage to care for substance use disorders, reduce health care expenditures, and reduce drug overdoses. Concerns about SSPs and increases in syringe litter or crime have not been borne out by research. Despite these findings and the positions of professional organizations, contemporary research suggests that pharmacists may be reluctant to support SSPs and other programs that would increase supply of sterile injection supplies to their communities. CONCLUSION: The review of evidence in this commentary should help pharmacists better understand the evidence in favor of SSPs, the potential criticisms of SSPs, and the reasons that their profession is moving to support these programs.

Inpatient Management of Uncomplicated Skin and Soft Tissue Infections in 34 Veterans Affairs Medical Centers: A Medication Use Evaluation.

BACKGROUND: Skin and soft tissue infections (SSTIs) are a key antimicrobial stewardship target because they are a common infection in hospitalized patients, and non-guideline-concordant antibiotic use is frequent. To inform antimicrobial stewardship interventions, we evaluated the proportion of veterans hospitalized with SSTIs who received guideline-concordant empiric antibiotics or an appropriate total duration of antibiotics. METHODS: A retrospective medication use evaluation was performed in 34 Veterans Affairs Medical Centers between 2016 and 2017. Hospitalized patients who received antibiotics for uncomplicated SSTI were included. Exclusion criteria were complicated SSTI, severe immunosuppression, and antibiotics for any non-SSTI indication. Data were collected by manual chart review. The primary outcome was the proportion of patients receiving both guideline-concordant empiric antibiotics and appropriate treatment duration, defined as 5-10 days of antibiotics. Data were analyzed and reported using descriptive statistics. RESULTS: Of the 3890 patients manually evaluated for inclusion, 1828 patients met inclusion criteria. There were 1299 nonpurulent (71%) and 529 purulent SSTIs (29%). Overall, 250 patients (14%) received guideline-concordant empiric therapy and an appropriate duration. The most common reason for non-guideline-concordance was receipt of antibiotics targeting methicillin-resistant Staphylococcus aureus (MRSA) in 906 patients (70%) with a nonpurulent SSTI. Additionally, 819 patients (45%) received broad-spectrum Gram-negative coverage, and 860 patients (48%) received an antibiotic duration >10 days. CONCLUSIONS: We identified 3 common opportunities to improve antibiotic use for patients hospitalized with uncomplicated SSTIs: use of anti-MRSA antibiotics in patients with nonpurulent SSTIs, use of broad-spectrum Gram-negative antibiotics, and prolonged durations of therapy.

Effect of Dual Use of Veterans Affairs and Medicare Part D Drug Benefits on Antihypertensive Medication Supply in a National Cohort of Veterans with Dementia.

OBJECTIVE: To evaluate the effect of dual use of VA/Medicare Part D drug benefits on antihypertensive medication supply in older Veterans with dementia. DATA SOURCES/STUDY SETTING: National, linked 2007-2010 Veterans Affairs (VA) and Medicare utilization and prescription records for 50,763 dementia patients with hypertension. STUDY DESIGN: We used inverse probability of treatment (IPT)-weighted multinomial logistic regression to examine the association of dual prescription use with undersupply and oversupply of antihypertensives. DATA COLLECTION/EXTRACTION METHODS: Veterans Affairs and Part D prescription records were used to classify patients as VA-only, Part D-only, or dual VA/Part D users of antihypertensives and summarize their antihypertensive medication supply in 2010: (1) appropriate supply of all prescribed antihypertensive classes, (2) undersupply of ≥1 class with no oversupply of another class, (3) oversupply of ≥1 class with no undersupply, or (4) both undersupply and oversupply. PRINCIPAL FINDINGS: Dual prescription users were more likely than VA-only users to have undersupply only (aOR = 1.28; 95 percent CI = 1.18-1.39), oversupply only (aOR = 2.38; 95 percent CI = 2.15-2.64), and concurrent under- and oversupply (aOR = 2.89; 95 percent CI = 2.53-3.29), versus appropriate supply of all classes. CONCLUSIONS: Obtaining antihypertensives through both VA and Part D was associated with increased antihypertensive under- and oversupply. Efforts to understand how best to coordinate dual-system prescription use are critically needed.

Pharmacists' and prescribers' neonatal abstinence syndrome (NAS) prevention behaviors: a preliminary analysis.

Background Maternal opioid use and neonatal abstinence syndrome (NAS) incidence have increased markedly in the US in recent years. Objectives (1) To assess prescribers' and community pharmacists' guideline-based NAS prevention behaviors; (2) to describe providers' perceptions of contraceptive appropriateness in female patients of childbearing age. Method Cross-sectional study of 100 randomly selected primary care physicians, 100 prescribers authorized to engage in in-office treatment of opioid use disorders with buprenorphine, 100 pain management clinic directors, and 100 community pharmacists in Tennessee (N = 400 providers total) to evaluate self-reported engagement in 15 NAS prevention behaviors and perceived appropriateness of 8 contraceptive methods in opioid using women of childbearing age. Results An overall response rate of 17.5% was obtained. Pain clinic directors reported the most engagement in NAS prevention, engaging 80% or more of female patients of childbearing age prescribed an opioid in 11 prevention behaviors, followed by buprenorphine prescribers (8 behaviors), primary care physicians (5 behaviors), and community pharmacists (2 behaviors). Pain clinic directors, primary care physicians, and community pharmacists perceived oral contraceptive pills and patches to be as appropriate as long-acting, reversible forms of contraception (e.g., implants, injectable depots, intrauterine devices). Conclusion Provider engagement in behaviors that could prevent NAS is variable. Interventions should be implemented that equip providers to engage patients in conversations about long-acting, reversible contraception.

Isavuconazonium sulfate: a triazole prodrug for invasive fungal infections.

OBJECTIVE: To review the place in therapy of isavuconazole, the active metabolite of isavuconazonium sulfate, via a review of the available literature on drug chemistry, spectrum of activity, pharmacokinetic/pharmacodynamic profile and trials assessing clinical efficacy and safety. METHODS: Relevant data, original research articles and reviews, were gathered primarily through the use of a PubMed database search. The search was conducted without date restrictions in order to collect both historical and recent data regarding isavuconazole. KEY FINDINGS: Isavuconazole is a triazole currently approved not only for use in invasive aspergillosis and mucormycosis but also has demonstrable activity against Candida species and other common fungal pathogens. This drug has features which make it more clinically appealing compared to other azoles with similar indications. In specific, isavuconazole does not require a cyclodextrin vehicle due to its water solubility, and at present, does not require therapeutic drug monitoring. Moreover, isavuconazole has displayed improved safety and tolerability compared to voriconazole. Available data from Phase III clinical trials shows isavuconazole to be a possible therapeutic option to currently available therapies for which it is approved; however, clinical conclusions should be reserved until results have been published and more data from clinical use is reported. CONCLUSIONS: Isavuconazole is a new triazole with broad-spectrum antifungal activity including invasive aspergillosis and mucormycosis.
