Minding the gap and the value of metrics: Count of working pharmacists in the United States.

BACKGROUND: The Bureau of Labor Statistics (BLS) uses a single Standard Occupational Classification (SOC) code (29-1051) that reflects a traditional definition of pharmacist job functions. Pharmacists working in nontraditional roles would be categorized under other SOC codes and not included in the BLS pharmacist count. Knowing the magnitude of how many working pharmacists may not be included in the BLS pharmacist count would help determine whether the gap is a minor margin of error or a significant problem affecting pharmacist workforce projections. OBJECTIVES: The primary objective of this paper was to estimate the gap between the number of possibly working pharmacists and the BLS pharmacist count in 2019. A secondary objective was to examine BLS pharmacist counts in nontraditional roles and compare with published industry data. METHODS: The annual number of individuals receiving their first professional pharmacy degree from 1965 to 2019 (55 graduation cohorts) was adjusted using the expected survival rate to 2019 by age and gender and workforce participation rate in 2019 for pharmacists for each cohort and then summed across cohorts. Data sources included Accreditation Council for Pharmacy Education, U.S. Vital Statistics reports, and American Consumer Survey. One-way and scenario-based sensitivity analyses were conducted to vary professional occupation mortality advantage and pharmacist workforce participation rate assumptions. RESULTS: Based on the number of individuals receiving their first professional pharmacy degree between 1965 and 2019 (442,409), there were 356,998 possibly working pharmacists in 2019. This value indicates 45,798 more pharmacists (15%) may have been working in 2019 than the 311,200 employee pharmacists reported by BLS for 2019. A gap of 8000 to 46,000 more working pharmacists (3%-15%) versus BLS persisted after sensitivity analyses. CONCLUSION: The magnitude of possibly working pharmacists not included in BLS counts warrants further consideration of current pharmacist job projections, methods, and metrics to improve future projections and monitoring of the pharmacist labor force.

A multifaceted intervention improves antibiotic stewardship for skin and soft tissues infections.

OBJECTIVE: Assess the effectiveness of a multifaceted stewardship intervention to reduce frequency and duration of inappropriate antibiotic use for emergency department (ED) patients with skin and soft tissue infections (SSTI). We hypothesized the antibiotic stewardship program would reduce antibiotic duration and improve guideline adherence in discharged SSTI patients. DESIGN: Nonrandomized controlled trial. SETTING: Academic EDs (intervention site and control site). PATIENTS OR PARTICIPANTS: Attending physicians and nurse practitioners at participating EDs. INTERVENTION(S): Education regarding guideline-based treatment of SSTI, tests of antimicrobial treatment of SSTI, implementation of a clinical treatment algorithm and order set in the electronic health record, and ED clinicians' audit and feedback. RESULTS: We examined 583 SSTIs. At the intervention site, clinician adherence to guidelines improved from 41% to 51% (aOR = 2.13 [95% CI: 1.20-3.79]). At the control site, there were no changes in adherence during the "intervention" period (aOR = 1.17 [0.65-2.12]). The between-site comparison of these during vs. pre-intervention odds ratios was not different (aOR = 1.82 [0.79-4.21]). Antibiotic duration decreased by 26% at the intervention site during the intervention compared to pre-intervention (Adjusted Geometric Mean Ratio [95% CI] = 0.74 [0.66-0.84]). Adherence was inversely associated with SSTI severity (severe vs mild; adjusted OR 0.42 [0.20-0.89]) and purulence (0.32 [0.21-0.47]). Mean antibiotic prescription duration was 1.95 days shorter (95% CI: 1.54-2.33) in the time period following the intervention than pre-intervention period. CONCLUSIONS: A multifaceted intervention resulted in modest improvement in adherence to guidelines compared to a control site, driven by treatment duration reductions.

Oral fosfomycin use for pyelonephritis and complicated urinary tract infections: a 1 year review of outcomes and prescribing habits in a large municipal healthcare system.

BACKGROUND: The rising incidence of MDR uropathogens has driven increased use of oral fosfomycin for treatment of complicated urinary tract infections (cUTIs). However, there are limited data to support its use for cUTI, especially pyelonephritis. METHODS: We performed a retrospective review of all oral fosfomycin prescriptions between 1 January and 31 December 2017 in the Los Angeles County Department of Health Service system, the second largest US municipal health system. We examined demographics, clinical characteristics, adverse events and 30 day treatment success for patients with cUTI. Follow-up urine cultures till 31 December 2018 were examined for emergence of fosfomycin resistance. RESULTS: Of 154 patients prescribed fosfomycin, 99 (64%) had cUTI. Of these, 39 (39%) had lower tract, 37 (37%) pyelonephritis and 23 (23%) non-pyelonephritis upper tract cUTI. Escherichia coli ESBL producers were the predominant pathogens (73%). Of the 63 patients with 30 day follow-up, 49 (78%) had clinical success, including 16/20 (80%) treated for pyelonephritis. Treatment failure was associated with male sex (P < 0.01), urological abnormalities (P = 0.05), non-E. coli cUTI (P = 0.03) and receipt of <25% IV therapy prior to fosfomycin switch (P = 0.03). Of patients prescribed fosfomycin (n = 154), fosfomycin-resistant E. coli were found in 9/64 (14%) of the patients with follow-up urine cultures >30 days after initial treatment. CONCLUSIONS: Despite the lack of data supporting its use, we found that most patients receiving oral fosfomycin off-label for cUTI, including pyelonephritis, had clinical success. However, emergence of subsequent resistance warrants caution. Prospective comparative studies should be done to better evaluate oral fosfomycin use for cUTI.

Characterization of COVID-19 Vaccine Hesitancy Among Essential Workforce Members of a Large Safety Net Urban Medical Center.

OBJECTIVES: Vaccine hesitancy among essential workers remains a significant public health challenge. We examined psychological constructs of perceived susceptibility, threat, and self-efficacy and their associations with COVID-19 vaccine hesitancy among a racially and ethnically diverse essential workforce population. METHODS: We performed a cross-sectional survey of essential workers from September-December 2020 at a large Los Angeles safety-net medical center as part of a program offering free COVID-19 serology testing. Program participants completed a standardized survey at the time of phlebotomy. Hierarchical logistic regression was utilized to determine factors independently associated with vaccine hesitancy. RESULTS: Among 1327 persons who had serology testing, 1235 (93%) completed the survey. Of these, 958 (78%) were healthcare workers. Based on expressed intent, 22% were vaccine-hesitant 78% were vaccine acceptors. In our multivariate model, vaccine hesitancy was associated with female gender [aOR = 2.09; 95% CI (1.44-3.05)], African American race [aOR = 4.32; (2.16-8.62)], LatinX ethnicity [aOR = 2.47; 95% CI (1.51-4.05)] and history of not/sometimes receiving influenza vaccination [aOR = 4.39; 95% CI (2.98-6.48)]. Compared to nurses, vaccine hesitancy was lower among physicians [aOR = 0.09; 95% CI (0.04-0.23)], non-nursing/non-physician healthcare workers [aOR = 0.55; 95% CI (0.33-0.92)], and non-healthcare care workers [aOR = 0.53; 95% CI (0.36-0.78)]. CONCLUSIONS: Among a racially/ethnically diverse group of safety net medical center essential workers, COVID-19 vaccine hesitancy was associated with racial/ethnic minority groups, employment type, and prior influenza vaccination hesitancy. Interestingly, we found no association with the Health Belief Model construct measures of perceived susceptibility, threat, and self-efficacy. Psychological constructs not assessed may be drivers of vaccine hesitancy in our population.

Prospective, open-label investigation of the pharmacokinetics of daptomycin during cardiopulmonary bypass surgery.

As methicillin-resistant Staphylococcus aureus (MRSA) becomes more prevalent, vancomycin is becoming increasingly used as a prophylaxis against surgical-site infections for cardiothoracic surgeries. However, vancomycin administration can be challenging, and the pharmacokinetics of alternative antibiotics in this setting are poorly understood. The primary objective of this investigation was to describe the pharmacokinetics of daptomycin in patients undergoing coronary artery bypass graft surgery. We enrolled 15 patients undergoing coronary artery bypass surgery requiring cardiopulmonary bypass. Each subject was administered a single open-label dose of daptomycin (8 mg/kg of body weight) for surgical prophylaxis. Fourteen daptomycin plasma samples were collected. Safety outcomes between subjects who received daptomycin and 15 control subjects who received the standard-of-care antibiotic were compared. The mean maximal concentration of daptomycin (C(max)) was 84.4 ± 27.1 µg/ml; the mean daptomycin concentration during the cardiopulmonary bypass procedure was 33.2 ± 11.4 µg/ml and was 30.9 ± 12.7 µg/ml at sternum closure. Mean daptomycin concentrations at 12, 18, 24, and 48 h were 22.7 ± 9.7, 16.2 ± 8.2, 12.0 ± 4.7, and 3.5 ± 2.3 µg/ml, respectively. Mean daptomycin concentrations were consistently above the MIC at which 90% of the tested isolates are inhibited (MIC90) for S. aureus and S. epidermidis during the cardiopulmonary bypass procedure. Daptomycin was not associated with surgical-site infections or differences in adverse events compared to findings for control subjects. We found that a single dose of daptomycin at 8 mg/kg was well tolerated and achieved adequate plasma concentrations against common pathogens associated with surgical-site infections after cardiothoracic surgery. Daptomycin may be considered an alternative surgical prophylaxis antibiotic for patients undergoing cardiothoracic bypass surgery who are unable to receive vancomycin.

Treatment for Positive Urine Cultures in Hospitalized Adults: A Survey of Prevalence and Risk Factors in 3 Medical Centers.

BACKGROUND: Antibiotic treatment for asymptomatic bacteriuria (ASB) is prevalent but often contrary to published guidelines. OBJECTIVE: To evaluate risk factors for treatment of ASB. DESIGN: Retrospective observational study. SETTING: A tertiary academic hospital, county hospital, and community hospital. PATIENTS: Hospitalized adults with bacteriuria. METHODS: Patients without documented symptoms of urinary tract infection per Infectious Diseases Society of America (IDSA) criteria were classified as ASB. We examined ASB treatment risk factors as well as broad-spectrum antibiotic usage and quantified diagnostic concordance between IDSA and National Healthcare Safety Network criteria. RESULTS: Among 300 patients with bacteriuria, ASB was present in 71% by IDSA criteria. By National Healthcare Safety Network criteria, 71% of patients had ASB; within-patient diagnostic concordance with IDSA was moderate (kappa, 0.52). After excluding those given antibiotics for nonurinary indications, antibiotics were given to 38% (62/164) with ASB. Factors significantly associated with ASB treatment were elevated urine white cell count (65 vs 24 white blood cells per high-powered field, P<.01), hospital identity (hospital C vs A, odds ratio, 0.34 [95% CI, 0.14-0.80], P =.01), presence of leukocyte esterase (5.48 [2.35-12.79], P<.01), presence of nitrites (2.45 [1.11-5.41], P=.03), and Escherichia coli on culture (2.4 [1.2-4.7], P=.01). Of patients treated for ASB, broad-spectrum antibiotics were used in 84%. CONCLUSIONS: ASB treatment was prevalent across settings and contributed to broad-spectrum antibiotic use. Associating abnormal urinalysis results with the need for antibiotic treatment regardless of symptoms may drive unnecessary antibiotic use.
