Utilizing Pharmacists to Optimize Medication Management Strategies During the COVID-19 Pandemic.

As the COVID-19 pandemic swept through the United States, our heath-system mobilized clinical pharmacy services to address critical clinical medication management needs. Reinforcing recommended medication management strategies for clinical pharmacists was key to successful implementation. Best practice strategies include converting patients from intravenous (IV) to oral medication, transitioning to IV push medication administration, evaluating standard medication administration timing, reviewing metered dose inhaler (MDI) and nebulizer utilization, using alternatives for medications in short supply, reviewing coronavirus disease COVID-19 treatment recommendations, reviewing COVID-19 patient care on interdisciplinary rounds, de-prescribing and de-escalating to eliminate unnecessary medications, and assessing for appropriate venous thromboembolism prophylaxis. These strategies served to help protect medication supply, reduce number of staff entries into patient rooms to conserve personal protective equipment, limit nursing time in patient rooms to reduce COVID-19 exposure risk, and to conserve compounding supplies. Here we present example medication management guidance as used by a large healthcare system during the COVID-19 pandemic.

Characteristics Contributing to a Pharmacy Services Excellence Model in a Large Health System.

Objective: To identify characteristics that contribute to and promote a pharmacy services center of excellence model in a large health system. Methods: In 2019, a survey was conducted of 161 acute care pharmacy departments of health system-affiliated hospitals. Information captured included pharmacy practice models, pharmacist resource allocation, training of pharmacy residents, postgraduate training and pharmacist certifications. Results were combined with clinical pharmacy metric performance and centralized electronic data to identify features of top performing pharmacy departments. Results: Survey results were received from 141 of 161 affiliated hospitals (88%). Hospitals with 100 to 299 beds comprised 54% (n = 16 of 30) of the hospitals "at goal" and 66% (n = 26 of 40) of hospitals with "opportunity". Hospitals with top performing pharmacy services had greater participation in interdisciplinary rounds, reporting "always" participating in Adult Critical Care (67% versus 43%) and Medical/Surgical (30% vs. 8%) rounds. Hospitals that trained pharmacy residents had a greater number of clinical pharmacy metrics at goal (5.89 ± 1.59 versus 4.16 ± 1.86, p < 0.001), employed more board-certified pharmacists (2.32 ± 1.49 versus 1.57 ± 1.62, p = 0.019), more postgraduate year 1 (PGY1) trained pharmacists (2.06 ± 1.33 versus 1.19 ± 1.19, p < 0.001) and more PGY2 trained pharmacists (0.58 ± 0.64 versus 0.19 ± 0.44, p = 0.002). When including several key hospital characteristics into a single model, hospitals that trained pharmacy residents were significantly associated with achieving "at goal" status (p = 0.011). Conclusion: Defining characteristics of a pharmacy services center of excellence model included "at goal" clinical pharmacy metrics performance, clinical pharmacist time dedicated to patient care activities, accredited pharmacy residency training programs, presence of pharmacists with advanced training or board certification and optimal operations and scheduling.

COVID-19: The Vaccine Race Continues.

Description Over a year has passed since the discovery of SARS-CoV-2 and the subsequent COVID-19 pandemic. As mitigation efforts continue, COVID-19 has claimed over half a million lives in the United States and 3.1 million lives globally. The development and availability of vaccines delivering immunity to prevent COVID-19 offers hope to end the pandemic. Emergency use authorizations from the Food and Drug Administration have been issued in the United States for three vaccines, one each from Pfizer-BioNTech, Moderna and Janssen/J&J. Pfizer-BioNTech and Moderna are both mRNA vaccines with efficacy of 95% and 94.1% respectively, while the vector-based vaccine from Janssen/J&J has an overall efficacy of 66.1%. The Janssen/J&J vaccine, having received the most recent authorization, is an attractive option due to high efficacy with a single dose. With a high immunity rate of 70-80% needed to prevent the continued spread of the virus and mutations, the majority of the population will require vaccination. The rise of mutations from selective pressure has further increased the urgency. Recent discoveries of variants have led to uncertainties regarding the impact of immunity and effectiveness of vaccines. In order to end the global pandemic, it is essential that the Centers for Disease Control and World Health Organization monitor the variant potential and educate the public appropriately to encourage appropriate vaccination and allocation of product. Achieving high vaccination rates in the U.S. has been challenged by supply, storage requirements and public hesitancy. In a recent Gallup poll, a random sample of 4,098 adults demonstrated that 71% of survey respondents were willing to receive a vaccine, which remains on the lower end of the 70-80% vaccination range required to end this pandemic. Despite these challenges, the United States has managed to surpass 225 million vaccinations.

Innovative Conservation of Inhaled Medication Devices During the COVID-19 Pandemic Through a Canister Reassignment Process.

Background: The ideal practice for patients requiring metered-dose inhalers (MDI) with coronavirus disease 2019 (COVID-19) is to use patient specific MDIs. However, this practice may not be possible during a time of increased usage throughout the country and limited availability of the medication. Nebulized medications are a concern due to the potential for aerosolized virus and increased exposure for health care workers. An alternative program of canister reassignment is proposed to address concerns for infection prevention, cross-contamination of MDI canisters and the shortage of MDI's due to the COVID-19 pandemic. Methods: A comprehensive MDI canister reassignment process was developed for facilities affiliated with a large health care system in response to the COVID-19 pandemic. The MDI canister reassignment process consisted of 4 components: preservation of supply, reassignment workflow, canister cleaning and operational integration. Albuterol MDI administration data was monitored from January 1st to August 31st, 2020. Results: Following development and rapid implementation of a comprehensive canister reassignment process, albuterol MDI administration data was reviewed from 162 hospitals affiliated with a large health care system. At baseline (prior to the COVID-19 pandemic), 98% of patients received a nebulizer vs. an MDI. After the implementation of the MDI reassignment process (during the COVID-19 pandemic), nebulizer usage decreased by 60% from March 6th to March 31st and was sustained with >50% reduction through August 31st. Conclusion: MDI canister reassignment was an instrumental process to allow the continued delivery of pharmacologic bronchodilator therapy for COVID-19 patients. It also represents an important infection prevention strategy needed to protect our health care providers from the potential aerosolized virus associated with nebulizers.

Covid-19: Race For A Vaccine.

Description The world is in the midst of a pandemic from COVID-19, a disease caused by the virus SARS-CoV-2. Despite broad mitigation efforts, new cases continue with 74 million cases and 1.6 million deaths worldwide. Regardless of previous research efforts, there is no commercially available vaccine for any coronavirus. Novel vaccine development has historically taken at least 10 years from discovery to availability with only a 6% market entry probability. With the global impact, there is an urgency to expedite a vaccine to protect the population. The U.S. government launched Operation Warp Speed with the goal to produce and deliver 300 million doses of safe and effective vaccines by January 2021. Efforts toward this goal have included coordinated government agency support, parallel clinical trial deployment, de-risking manufacturing earlier in the development process and real-time U.S. Food & Drug Administration evaluation of the safety and efficacy data. Safety is a priority and key analysis has not been eliminated during the compressed timeframe. The two frontrunner candidates show promising efficacy rates for preventing COVID-19 with Moderna reporting 94.1% efficacy and Pfizer reporting 95.0% efficacy. Despite the herculean efforts by scientists to develop an effective vaccine in such a short timeframe, several national surveys suggest that public confidence in these vaccines is low with less than 50% of the survey respondents willing to be vaccinated. According to experts, the U.S. needs the vaccine to be at least 70-80% effective and a 70-80% vaccination rate in order to return to normal. Significant education and promotion is planned in coordination with the Centers for Disease Control.

Effectiveness of a clinical decision support system to identify heparin induced thrombocytopenia.

BACKGROUND: Subtle decreases in platelet count may impede timely recognition of heparin-induced thrombocytopenia (HIT), placing the patient at increased risk of thrombotic events. OBJECTIVE: A clinical decision support system (CDSS) was developed to alert physicians using computerized provider order entry when a patient with an active order for heparin experienced platelet count decreases consistent with HIT. METHODS: Comparisons for timeliness of HIT identification and treatment were evaluated for the year preceding and year following implementation of the CDSS in patients with laboratory confirmation of HIT. RESULTS: During the intervention time period, the CDSS alert occurred 41,922 times identifying 2,036 patients who had 2,338 inpatient admissions. The CDSS had no significant impact on time from fall in platelet count to HIT laboratory testing (control 2.3 days vs intervention 3.0 days P = 0.30) and therapy (control 19.3 days vs intervention 15.0 days P = 0.45), and appeared to delay discontinuation of heparin products (control 1.3 days vs. intervention 2.9 days P = 0.04). However, discontinuation of heparin following shorter exposure duration and after smaller decrease in platelet count occurred during the intervention period. The HIT CDSS sensitivity and specificity were each 87% with a negative predictive value of 99.9% and positive predictive value of 2.3%. CONCLUSIONS: Implementation of a CDSS did not appear to improve the ability to detect and respond to potential HIT, but resulted in increased laboratory testing and changes in clinician reactions to decreasing platelet counts that deserve further study.

Interaction between levodopa and enteral nutrition.

OBJECTIVE: To report and discuss a drug-nutrient interaction involving levodopa and protein in enteral nutrition. CASE SUMMARY: A 77-year-old male with Parkinson's disease was admitted to an intensive care unit for an intracerebral hemorrhage. To provide nutritional support, an oral gastric tube was placed and continuous enteral nutrition was initiated, with 1.4 g/kg of protein administered daily. The following medications were continued during hospitalization: immediate-release carbidopa/levodopa 25 mg/100 mg, with 1.5 tablets administered 4 times daily; pramipexole 1.5 mg 3 times daily; and entacapone 200 mg 4 times daily. Despite this drug therapy, the patient developed severe rigidity. A review of the literature revealed a potential interaction between levodopa and protein intake. To resolve this interaction, the amount of protein in the enteral nutrition was decreased to 0.9 g/kg/day and the nutritional administration was changed from continuous enteral feeding to bolus feeding, with levodopa given between boluses. After these adjustments, the patient showed marked improvement of parkinsonian symptoms. DISCUSSION: The drug-nutrient interaction between protein and levodopa in outpatient settings has been reported widely in the literature; however, this interaction has not been previously reported with continuous enteral nutrition. Decreased parkinsonian symptom control, despite adherence to an established medication regimen, together with dramatic improvement observed after manipulation of enteral nutrition delivery and content, strongly suggest interference with levodopa absorption. Use of the Naranjo probability scale supports a probable interaction between the protein content in tube feeds and levodopa, resulting in decreased levodopa efficacy. CONCLUSIONS: Clinicians should be cognizant of the potential drug-nutrient interaction between levodopa and enteral nutrition.
