Pharmacists as Frontline Responders During COVID-19: Roles and Responsibilities Need to be Revisited.

The ongoing pandemic has disrupted the health care system, creating challenges for health care workers and patients alike. As workflows and job responsibilities have been adapted to provide care to coronavirus-infected patients, many primary care services have been postponed. This change has led to significant financial impacts that will be difficult to overcome. Ambulatory care pharmacists can help fill gaps both in access to primary care services and in the financial deficit, if given the opportunity to practice at the top of their skillset and bill for their face-to-face and telehealth services both during and after the pandemic.

Clinical and Economic Implications of Restrictions on Calcitonin Utilization in a Health System.

Background: Hypercalcemia is a relatively common problem that may require hospital admission based on severity. A treatment option for hypercalcemia is calcitonin given intramuscularly or subcutaneously. Purpose: In 2015, calcitonin was on our health system formulary, but due to a sharp rise in cost, restrictions were placed to ensure appropriate utilization. Intervention: These restrictions reserved calcitonin for patients with symptomatic hypercalcemia or severe hypercalcemia, which was defined as an ionized calcium of greater than 1.5 mmol/L and/or total/corrected calcium (Ca) of greater than 13 mg/dL. In addition to providing criteria for its use, calcitonin orders also had an automatic stop date of 24 hours to ensure no more than 2 doses were provided in a 24-hour period. After the initial 24 hours, a patient would have to be reviewed again before any further doses were ordered and administered. If the patient met criteria, an additional 2 doses could be given in the next 24 hours for a total maximum treatment of 4 doses over a 48-hour time frame. Results: An evaluation to assess health system-wide compliance of the usage of calcitonin restrictions regarding utilization, effectiveness, and cost was conducted. In the 2-month study time frame that was examined, there was a decrease in 66 vials of calcitonin that were dispensed. This represents a 43% reduction in usage and an estimated US $450,000 reduction in the total money spent for calcitonin annually. No notable differences in Ca reduction were identified between the groups. Conclusion: This evaluation revealed that putting health system-wide restrictions in use for a high-cost medication can have a major financial impact without compromising clinical efficacy.

Antithrombotic Usage Patterns in the Era of New Oral Anticoagulant Options for Atrial Fibrillation.

BACKGROUND: Appropriate treatment reduces the risk of stroke in patients with atrial fibrillation (AF). Despite the known benefits of warfarin, anticoagulation prescribing rates remain inadequate in high-risk patients. Over the last 6 years, 4 novel oral anticoagulants have been approved for use for stroke prophylaxis in non-valvular AF (NVAF), which may allow prescribers to tailor therapy for each NVAF patient. OBJECTIVE: The goal of this investigation was to determine the effect of dabigatran and rivaroxaban availability on the rate of anticoagulant prescribing at hospital discharge in patients with a principal diagnosis of NVAF. METHODS: A retrospective chart review of adult patients presenting with NVAF (CHADS2 score ≥2) was conducted using a historical control group of patients from 2009 compared to patients admitted in 2012 following formulary availability of dabigatran and rivaroxaban. In addition to antithrombotic therapy prescribed, subsequent hospitalizations during a 1-year period were reviewed for major bleeding and stroke events. RESULTS: Two hundred patients were enrolled in the study. The rate of anticoagulant prescribing in the 2009 and 2012 groups was 68.3% and 77.1%, respectively (p = .16). Of the patients in the 2012 group prescribed an anticoagulant, 58 (64%) received warfarin, 26 (28%) received dabigatran, and 7 (8%) received rivaroxaban. One patient (1.2%) in the 2009 group and 4 patients (4.4%) in the 2012 group had a major bleed (p = .4). CONCLUSION: There was no statistical difference in the rate of anticoagulant prescribing between the 2 groups. Despite the availability of additional anticoagulant options, the rate of prescribing remains suboptimal in this high-risk population.

Evaluation of the treatment of methicillin-resistant Staphylococcus aureus bacteremia.

BACKGROUND: Bloodstream infections are a leading cause of death in the United States. Methicillin-resistant Staphylococcus aureus (MRSA) encompasses >50% of all S aureus strains in infected hospitalized patients and increases mortality, length of stay and healthcare costs. The objective of this study was to evaluate the treatment of MRSA bacteremia with daptomycin, linezolid and vancomycin. METHODS: Patients with MRSA bacteremia between June 2008 and November 2010 were reviewed retrospectively. A microbiology laboratory report identified patients with ≥ 1 positive MRSA blood culture. Patients ≥ 18 years receiving daptomycin, linezolid or vancomycin for ≥ 7 consecutive days were included. Polymicrobial blood cultures and patients treated concomitantly with >1 anti-MRSA agent were excluded. RESULTS: Of 122 patients included, 53 received daptomycin, 15 received linezolid and 54 received vancomycin. Clinical and microbiologic cure rates were similar between daptomycin, linezolid and vancomycin (58.5% versus 60% versus 61.1%; 93.6% versus 100% versus 90%, respectively). Thirteen patients (daptomycin 4/24 versus linezolid 1/9 versus vancomycin 8/49, P = 0.5960) had recurrence while 12 patients had re-infection (daptomycin 5/42 versus linezolid 0/9 versus vancomycin 7/49, P = 0.4755). Treatment failure occurred in 11 patients treated with daptomycin, 4 with linezolid and 9 with vancomycin (P = 0.662). Compared with daptomycin and vancomycin, linezolid-treated patients had higher mortality (P = 0.0186). CONCLUSIONS: No difference in clinical or microbiologic cure rates was observed between groups. Daptomycin and vancomycin appear equally efficacious for MRSA bacteremia, whereas linezolid therapy was associated with higher mortality.

Nitrofurantoin-induced hepatotoxicity: a rare yet serious complication.

Nitrofurantoin is a commonly prescribed antibiotic for the treatment of recurrent uncomplicated urinary tract infections. Its importance has been emphasized by the current international clinical practice guidelines for the management of uncomplicated cystitis. Since its introduction into clinical practice, nitrofurantoin has been associated with various adverse effects, including hepatotoxicity. We searched the English-language literature using PubMed and SCOPUS for the period 1961 through the end of February 2013. Key search terms included "nitrofurantoin AND hepatotoxicity" as well as "nitrofurantoin AND hepatitis." When studies or case reports were found, we assessed articles cited in those publications. A broad spectrum of liver toxicity associated with nitrofurantoin use has been reported, ranging from acute hepatitis, granulomatous reaction, cholestasis, or autoimmune-mediated hepatitis to chronic active hepatitis that could lead to cirrhosis or death. The mechanism of hepatotoxicity is poorly understood, but it is believed to be the result of an immunologic process or a direct cytotoxic reaction. It has been postulated that prolonged exposure to nitrofurantoin, female sex, advanced age, and reduced renal function increase the risk of developing hepatotoxicity. For the management of severe cases, corticosteroids have been used along with nitrofurantoin discontinuation. Because of mixed results, the utility of corticosteroids has not been proven and should be used judiciously. Given the severity and seriousness of the adverse effect of hepatotoxicity, clinicians should weigh the risks and benefits of nitrofurantoin before initiating therapy, especially in long-term prophylaxis in high-risk patients. Clinicians also should be well versed in recognizing and managing liver injury associated with nitrofurantoin.

Acute ascending muscle weakness secondary to medication-induced hyperkalemia.

Secondary hyperkalemic paralysis is an uncommon but potentially life-threatening consequence of drug-induced disease. We report a case of a 53-year-old female with history of chronic kidney disease presenting to the emergency department with a one-day history of upper and lower extremity weakness and paresthesias. Serum potassium concentration on admission was greater than 8 mEq/L, and serum creatinine was elevated above baseline. Electrocardiogram showed first-degree atrioventricular block with peaked T waves. The patient reported compliance with daily lisinopril 10 mg, spironolactone 25 mg, and 40 mEq twice daily of potassium chloride. Symptoms and electrocardiogram returned to baseline within 24 hours of presentation and serum potassium returned to 4.2 mEq/L at approximately 36 hours without the need for dialysis. This case emphasizes the importance of including such a condition in the differential diagnosis of patients with ascending paralysis and the importance of close monitoring of patients placed on potassium-elevating agents.

Vancomycin-resistant Enterococcus bacteremia: an evaluation of treatment with linezolid or daptomycin.

BACKGROUND: Due to high rates of resistance and a limited number of efficacious antimicrobials for vancomycin-resistant Enterococcus (VRE), appropriate antibiotic selection is vital to treatment success. The purpose of this study was to assess clinical and microbiologic outcomes associated with the use of linezolid or daptomycin in the treatment of VRE bacteremia. METHODS: A retrospective analysis of adult patients with VRE bacteremia between January 2004 and July 2009 was conducted at a tertiary care hospital in the United States. Clinical and microbiologic outcomes for both therapies were evaluated using multiple criteria. RESULTS: Of the 361 patients with VRE bacteremia identified, 201 were included in the study (linezolid group, n = 138; daptomycin group, n = 63). More patients in the daptomycin group had hematologic malignancies (33% vs 14%) or received liver transplants (13% vs 4%). There was no difference in clinical or microbiologic cure between the linezolid and daptomycin groups (74% vs 75% and 94% vs 94%, respectively). Recurrence was documented in 3% of linezolid patients vs 12% of daptomycin patients (P = 0.0321). Reinfection was noted in 1% of patients in the linezolid group vs 6% of patients in the daptomycin group (P not significant). The average length of stay (LOS) was 37 days for the linezolid group vs 40 days for the daptomycin group (P not significant). Overall mortality was 20%, occurring in 25/138 linezolid patients vs 15/63 daptomycin patients (P not significant). CONCLUSIONS: No differences in clinical or microbiologic cure rates, LOS, or mortality were identified between the groups. Various factors may have contributed to the significantly higher recurrence of VRE bacteremia in daptomycin patients. This study suggests that linezolid and daptomycin appear equally efficacious in the treatment of VRE bacteremia.

An evaluation of inhaled bronchodilator therapy in patients hospitalized for non-life-threatening COPD exacerbations.

OBJECTIVE: Chronic obstructive pulmonary disease (COPD) increasingly is a cause of morbidity and mortality in and economic burden on the US healthcare system, and COPD exacerbations continue to be among the top 10 causes of hospitalization in adults. The objective of this study was to evaluate the incidence and potential implications of missed scheduled nebulized bronchodilator therapy in the setting of acute, non-life-threatening COPD exacerbations. MATERIALS AND METHODS: This study was a retrospective chart review of all of the patients with a primary diagnosis of severe, non-life-threatening COPD exacerbations admitted from January 2007 to June 2008 at a university-affiliated hospital. Each patient's inhaled bronchodilator treatment regimen, including potential for nebulization to metered-dose inhaler (MDI) with valved holding chamber (VHC) conversion, was assessed. RESULTS: A total of 259 patients met inclusion criteria: 235 (90.7%) patients received inhaled bronchodilators by nebulization alone in the treatment of COPD exacerbations; 81.1% of these patients could have used MDI with VHC. Patients missed 24.3% of their scheduled, nebulized bronchodilator doses. CONCLUSIONS: Patient care can be improved through the initiation of MDI with VHC, especially considering the number of missed nebulizations that these patients experienced. Development of an inhaled bronchodilator treatment algorithm for COPD exacerbations should be considered to ensure an evidence-bassed medicine approach to these patients.

Gabapentin withdrawal syndrome in a post-liver transplant patient.

A 41-year-old male with a previous orthotopic liver transplant began experiencing insomnia, anxiety, diaphoresis, headaches, and palpitations that progressed over a 2-day period. As part of his home medication regimen, the patient was taking gabapentin for peripheral neuropathy. His acute onset of increasing symptoms coincided with an inadvertent discontinuation of gabapentin. After reinitiation of gabapentin therapy, the symptoms slowly improved over the next 24 hours and the episode of gabapentin withdrawal syndrome resolved.

Are we failing to document adequate smoking histories? A brief review 1999-2009.

BACKGROUND: Documenting a detailed smoking history is of obvious importance. Failure to adequately document the smoking history may result in the misdiagnosis and management of asthma, and may be associated with a deficiency of care in patients with cardiovascular disease and several other common diseases. SCOPE: The purpose of this article is to review the evidence over the past decade that demonstrates inadequate documentation of smoking history. A literature search of English language journals from 1999 to 2009 was completed using several databases, including PubMed, MEDLINE, EMBASE, and SCOPUS. FINDINGS: Fourteen studies demonstrated inadequate documentation of smoking histories by primary care clinicians, specialists, residents, and medical students. Failure to document smoking histories was observed in patients with conditions such as heart failure, coronary artery disease, and asthma. Electronic decision support systems and simple medical record reminders were effective in improving the documentation of smoking histories. CONCLUSIONS: Failure to adequately document the smoking history appears to be common. Strategies such as electronic decision support systems are needed to correct this problem in order for patients to receive optimal therapy for their appropriate diagnoses.

A prospective evaluation and literature review of levetiracetam use in patients with brain tumors and seizures.

To determine the safety and tolerability of IV and oral levetiracetam monotherapy for seizures in brain tumor patients following resection. Brain tumor patients undergoing neurosurgery with >or=1 seizure within the preceding month prior to surgery were enrolled to receive intravenous levetiracetam for a minimum of 48 h, transitioned to oral levetiracetam at the same dose, and followed for 1-month after discharge. Patients were assessed daily in the hospital, provided with a seizure diary, and supplied with 30 days of levetiracetam upon discharge. Study patients were telephoned weekly to assess their cognitive status and seizure frequency. Of the 17 patients enrolled, the baseline seizure types were tonic clonic, partial, and complex partial with secondary generalization. The most common type of tumor was glioblastoma multiforme. Levetiracetam was well tolerated with no medication discontinuation during the study period. Adverse effects reported were somnolence, nausea/vomiting, headache, and insomnia. Eleven patients were evaluable for TICS scores (64.7%) with an average score of 33.3. Two patients were deemed to be cognitively impaired (18.2%). Eleven of twelve patients (91.7%) that completed the study period achieved a >or=50% reduction in their number of seizures. A total of 92 drug interactions were avoided (P = 0.0016) with dexamethasone, acetaminophen, and fentanyl being the most common. Levetiracetam monotherapy was found to be safe and tolerable in this patient population. Nearly all patients achieved a >or=50% reduction in seizure frequency post-op with levetiracetam monotherapy. Levetiracetam also has the potential for less drug interactions compared to phenytoin in these patients.

Inadequate documentation of asthma management in hospitalized adult patients.

Undocumented patient information in the medical record (MR) is a barrier to providing high quality care. Inadequate documentation has recently been reported for two cardiovascular diseases. This study was designed to evaluate the documentation of asthma management in the MR to determine if it is consistent with the NIH asthma guidelines. We performed a retrospective chart review of patients (ages 18-49) admitted to the hospital with an ICD-9 code for a primary diagnosis of asthma between January 2004 and May 2007. Patients admitted with a hospitalization for >24 hours and had <10 pack per year smoking history were included. We assessed medication regimens, documentation of asthma education, asthma action plans, referrals, and exacerbating factors. There were 233 admissions for 144 unique patients analyzed. At discharge, 85% of patients lacked documentation of asthma education, 97% lacked documentation of a written asthma action plan being given, and 79% did not have referral to an asthma specialist. Respiratory infection was the most common factor associated with admission; 58% of admissions were lacking documentation of the exacerbating factor. Only 47% of patients were receiving inhaled corticosteroids (ICS) prior to admission; 25% of patients did not have ICS prescribed for maintenance therapy upon discharge. Documentation of asthma management, specifically asthma education in the MR, is insufficient and may reflect a deficiency in care. Additionally, an inadequate number of patients were receiving ICS for maintenance therapy. Based on these findings, mechanisms are needed to ensure appropriate documentation and optimal care.

Potential role of leukotriene modifiers in the treatment of chronic obstructive pulmonary disease.

Abstract Chronic obstructive pulmonary disease (COPD) is characterized by progressive, irreversible airflow limitation coupled with an abnormal inflammatory process. It is associated with high morbidity and mortality. Leukotriene modifiers, approved by the United States Food and Drug Administration as treatment for asthma and allergic rhinitis, may also alleviate the abnormal inflammatory response seen in patients with COPD. To explore the outcomes of research in this area, we conducted a literature search from 1950-2007, using the PubMed database. We found no published studies that provided conclusive evidence that the available leukotriene modifiers benefit patients with COPD. However, data do suggest that leukotriene modifiers may offer benefits to patients with COPD, including effects that pertain to airflow limitation, neutrophil and lymphocyte chemotaxis, and neutrophil longevity. Added to conventional treatment, these agents appear to reduce symptoms, improve objective measures of disease, and control inflammation. Further studies are needed to determine the precise role of leukotriene modifiers in the treatment of COPD.

Heparin-induced thrombocytopenia complicated by warfarin-induced skin necrosis.

PURPOSE: A case of heparin-induced thrombocytopenia (HIT) complicated by warfarin-induced skin necrosis (WISN) is reported. SUMMARY: A patient with a history of hypertension, heart failure, and myocardial infarction was admitted to the hospital after complaining of a two-day history of shortness of breath, diaphoresis, and chest pain. The patient underwent a cardiac catheterization and received several medications, including heparin. Suspicions of HIT occurred when her platelets began to decrease severely and she developed a left groin hematoma and a pseudoaneurysm. Lepirudin was initiated and a heparin platelet factor 4 (PF4) antibody test was performed. The results were negative and lepirudin was discontinued. She was rechallenged with unfractionated heparin (UFH) after surgery of the pseudoaneurysm, but her platelets began to decrease again. A second PF4 test was performed, the results of which were positive. The UFH treatment was discontinued. Warfarin was also initiated after surgery and the patient's platelets rapidly increased after heparin was discontinued. She was discharged one week later. Three days after discharge, she was readmitted after complaining of severe pain and swelling of the fatty tissue of her right flank that began the day after she was discharged. Some blistering and necrosis were noted on the lesion. Histological sections showed focal thrombosis of vessels in the deep reticular dermis consistent with WISN. Local wound care was given to manage the WISN, lepirudin was initiated, and warfarin was discontinued and reinstated one week later at a low dosage. CONCLUSION: A patient with HIT developed severe skin necrosis after initiation of warfarin therapy.

Asthma treatment protocols in the emergency department: are they effective?

Management of asthma in emergency departments (ED) has been well documented to be deficient over many years, despite national and international guidelines. This review summarizes the effect of ED protocols aimed at improving the assessment and treatment of asthma in the ED. We performed a PubMed search of the English literature for ED asthma protocols published from 1986 to 2006 and identified 11 studies. Protocols were effective in improving at least some areas of management, including use of appropriate patient assessment, drug therapy per national guidelines, and patient education. A small number of protocols with the specific aims of reducing the length of stay in the ED as well as rates of hospital admission and return visits were effective. Persistent education of ED staff regarding protocols based on current management guidelines and adoption of easy-to-use forms can facilitate improved care of patients with asthma in the ED.
