Implementing outpatient antimicrobial stewardship in a primary care office through ambulatory care pharmacist-led audit and feedback.

OBJECTIVES: This study aimed to determine the impact of a pharmacist-led antimicrobial stewardship program (ASP) intervention on outpatient antibiotic prescribing for upper respiratory tract infections (URIs) and urinary tract infections (UTIs) in a primary care office. The primary outcome of this study was to characterize antibiotic prescribing over time. Secondary outcomes included describing ambulatory care pharmacist (ACP) workload and types of feedback given. METHODS: A retrospective pilot study was conducted within a primary care office. The office included a 0.6 full-time equivalent ACP and is part of a health system supported by a pharmacist and a physician co-led ASP. Education and guidelines were provided by the ACP and ASP leads before the intervention period August 2017-February 2018. The ACP provided bi-weekly audit of all URI and UTI prescriptions and written feedback to prescribers. RESULTS: During the 7-month intervention period, 1107 prescriptions were audited by the ACP, 825 URI and 282 UTI. The most common reasons for feedback included inappropriate agent (26.3%) or prolonged duration of therapy (24.3%). Guideline-concordant agent prescribed for a UTI increased from 20% at baseline to a median of 69.2%, whereas duration increased from 55% to 70.4%. Guideline-concordant agent prescribed for a URI increased from 43.3% to 86.8%, whereas the median duration of therapy decreased from 10 to 7 days. CONCLUSION: An ACP-led ASP intervention within a primary care office incorporating audit and feedback improved antibiotic prescribing for URIs and UTIs, including prescribing antibiotics when indicated, guideline-concordant antibiotic selection, and duration of therapy. Pharmacists practicing in ambulatory care settings may serve a vital role in leading successful outpatient ASP interventions.

Burden of relapsing-remitting multiple sclerosis on workers in the US: a cross-sectional analysis of survey data.

BACKGROUND: Multiple sclerosis (MS) is prevalent among working age individuals (20-60 years), leading to high burden on work productivity. Few data are available about the absenteeism and presenteeism in employed individuals with MS in comparison to non-MS personnel. This study aimed to quantify the burden of illness of employed US adults with relapsing-remitting multiple sclerosis (RRMS) and examine burden by levels of work impairment. METHODS: A retrospective cross-sectional analysis was conducted using patient-reported responses from the US National Health and Wellness Survey (NHWS). Data from NHWS 2015-2016 were analyzed from 196 employed RRMS respondents who were matched 1:4 to employed respondents without MS based on demographic and general health characteristics. Demographic and general health characteristics for employed RRMS individuals were analyzed by levels of work impairment (none, 1-30%; 31-68%; 69-100%). Work productivity (absenteeism, presenteeism, and work impairment), decrements in health-related quality of life (HRQoL) (short form-36, EQ-5D), and healthcare resource utilization (HCRU) were compared to determine the burden of RRMS. RESULTS: After propensity score matching, the levels of absenteeism and presenteeism were 2 and 1.8 times higher in the employed RRMS population than the employed non-MS population, respectively (P < 0.001 for both). HRQoL was significantly lower in employed respondents with RRMS than those without MS (P < 0.001 for all). Employed respondents with RRMS had significantly more HCRU over 6 months compared to those without MS (P < 0.001). Furthermore, among employed RRMS respondents, greater levels of impairment were associated with increasing disease severity, greater healthcare resource use, fatigue, and cognitive impairment and inversely associated with mental and physical HRQoL (P < 0.0001 for all). CONCLUSIONS: Among employed individuals, respondents with RRMS had lower, work productivity, HRQoL, and higher HCRU as compared with those without MS. Given the large impact RRMS has on work impairment, a need exists to manage individuals on therapies that improve HRQoL, reduce symptoms, and improve their ability to perform in the workforce.

A Comparative Analysis of Physical Therapy Anatomical Knowledge and Retention: Human Donor Dissection Versus Virtual Laboratory.

INTRODUCTION: Despite a long history of using human donor dissection (HDD) for physical therapy (PT) anatomy education, there are no PT guidelines that require HDD. The purpose of this quantitative causal-comparative study was to determine if Doctor of Physical Therapy students who used HDD had different grades both within anatomy and within courses that require retention and application of anatomical knowledge (kinesiology and a foundational musculoskeletal course) compared with those who used virtual 3-dimensional anatomical software (VAS). REVIEW OF LITERATURE: Numerous factors affect the decision to use HDD within PT anatomy, and few PT studies have compared the effectiveness of VAS to HDD. SUBJECTS: All students who took anatomy in an entry-level PT program from 2018 to 2021 (232 total students, 115 who used HDD in 2018-2019 and 117 who used VAS in 2020-2021). METHODS: Mann-Whitney tests were used to compare anatomy grades (course, written examination, and practical examination) and future grades in kinesiology and a foundational musculoskeletal course for students who used HDD or VAS. RESULTS: Physical therapy students who used VAS had statistically significant higher anatomy course grades (VAS 93.81% ± 4.99% to HDD 92.20% ± 4.53%) and higher practical examination grades (VAS 97.43% ± 2.91% to HDD 93.55% ± 4.39%) compared with those who used HDD. However, there were no significant differences between groups on written anatomy examinations (VAS 89.42% ± 7.21% to HDD 90.40% ± 4.94%), kinesiology grades (VAS 91.86% ± 4.52% to HDD 92.80% ± 4.27%), or foundational musculoskeletal grades (VAS 89.50% ± 3.89% to HDD 89.77% ± 3.83%). DISCUSSION AND CONCLUSION: The causal-comparative study design prevents concluding that PT student grade differences were due exclusively to either anatomy laboratory method. It does provide preliminary evidence that the PT anatomy laboratory method did not practically affect anatomy performance or long-term application of anatomy knowledge in future coursework.

Prescription drug misuse and risk behaviors among young injection drug users.

Prescription drug misuse among young adults, especially opioids, is a substantial public health problem in the United States. Although risks associated with injection of illicit drugs are well established, injection and sexual risks associated with misuse of prescription drugs are under-studied. Forty young injection drug users aged 16 to 25 who reported injection of a prescription drug were recruited in 2008-09 in Los Angeles and New York City. Descriptive quantitative and qualitative data were analyzed to illustrate risky injection and sexual behaviors reported in this sample. Over half of participants engaged in risky injection behavior, three-quarters engaged in risky sexual behavior, nearly half reported both risky behaviors, and five did not report either risk behavior while misusing a prescription drug. Prescription opioids, tranquilizers, and stimulants were misused in the context of risky sexual behaviors while only opioids were misused in the context of injection risk behaviors. Access to clean syringes, attitudes and beliefs regarding hepatitis C, and risk reduction through partner selection were identified as key themes that contextualized risk behaviors. Although these findings help identify areas to target educational campaigns, such as prevention of sexually transmitted infections, risk behaviors specifically associated with prescription drug misuse warrant further study.

Aging population and future burden of pneumococcal pneumonia in the United States.

Pneumococcal pneumonia is concentrated among the elderly. Using a decision analytic model, we projected the future incidence of pneumococcal pneumonia and associated healthcare utilization and costs accounting for an aging US population. Between 2004 and 2040, as the population increases by 38%, pneumococcal pneumonia hospitalizations will increase by 96% (from 401 000 to 790 000), because population growth is fastest in older age groups experiencing the highest rates of pneumococcal disease. Absent intervention, the total cost of pneumococcal pneumonia will increase by $2.5 billion annually, and the demand for healthcare services for pneumococcal pneumonia, especially inpatient capacity, will double in coming decades.

Balance Confidence and Balance Performance, But Not Fall History Are Associated With Quality of Life in Community-Dwelling Older Adults: A Cross Sectional Study.

BACKGROUND AND PURPOSE: Fear of falling (FoF) is highly prevalent in community-dwelling older adults and is associated with low health-related quality of life (QoL). Low QoL is associated with increased health care utilization and is a predictor of future falls, but few studies have examined the relationship between high-level balance and dynamic gait performance and QoL in community-dwelling older adults. The purpose of this cross-sectional study was to determine whether there is a relationship between FoF avoidance behaviors, balance confidence, performance on measures of high-level mobility, and QoL in community-dwelling older adults. The secondary purpose was to determine whether older adults who fall have a different QoL than older adults who have not fallen in the past year. METHODS: Eighty-nine community-dwelling older adults (76.33 ± 6.84 years, 54 female, 34 fallers) completed the World Health Organization Quality of Life-BREF (WHOQOL-BREF), Activities-specific Balance Confidence Scale (ABC), Fear of Falling Avoidance Behavior Questionnaire (FFABQ), Functional Gait Assessment (FGA), and Community Balance and Mobility Scale (CB&M). Correlation and multiple regression analyses were calculated to determine the relationship between the outcome measures and domains on the WHOQOL-BREF. RESULTS AND DISCUSSION: Significant correlations were observed between the WHOQOL-BREF physical health domain and the ABC, FFABQ, FGA, and CB&M (ρ= 0.524, -0.509, 0.348, and r = 0.423, respectively), the WHOQOL-BREF psychological domain and the ABC (ρ= 0.284) and FFABQ (ρ=-0.384), and the WHOQOL-BREF environment domain and the ABC (ρ= 0.343) and FFABQ (ρ=-0.406). No correlations were found between WHOQOL-BREF domain scores and a history of falls. CONCLUSIONS: Performance-based outcome measures that measure high-level mobility such as the CB&M and FGA, and patient-reported outcome measures for balance confidence and FoF avoidance behavior such as the ABC and FFABQ, are correlated with the physical health QoL domain on the WHOQOL-BREF. The ABC and FFABQ are correlated with psychological and environment QoL. Fall history was not correlated with QoL. Interventions to decrease FoF or improve high-level mobility may improve QoL in community-dwelling older adults.

Identifying disability level in multiple sclerosis patients in a U.S.-based health plan claims database.

AIMS: In clinical trials, disability progression in multiple sclerosis (MS) is measured by the Kurtzke expanded disability status scale (EDSS), which is not captured in routine clinical care in the U.S. This study developed a claims-based disability score (CDS) based on the EDSS for assigning MS disability level in a U.S. claims database. METHODS: This retrospective cohort study of patients with MS in the U.S., utilized adjudicated health plan claims data linked to electronic medical records (EMRs) data. Patients were identified between 1 January 2012 and 31 December 2016 and indexed on the first date of MS diagnosis. The CDS was developed to assign disability level at baseline using claims and ambulatory EMR records observed over the 1-year baseline period. All-cause healthcare costs were assessed by baseline disability level to validate the CDS. RESULTS: In total, 45,687 patients were identified in claims (full sample) and 1,599 linked to EMR (core sample). Over half of patients in both samples were classified with mild disability at baseline. Adjusted healthcare costs in patients with moderate and severe disability were 15% (p<.0001) and 20% higher, respectively, than in patients with mild disability at baseline in the full sample. Disease-modifying therapy (DMT) costs accounted for 89%, 82%, and 78% of outpatient pharmacy costs in patients with mild, moderate, and severe disability, respectively. CONCLUSIONS: The CDS is the first claims-based measure of MS disability utilizing data from EMR. This novel measure advances the opportunity to examine outcomes by disability accumulation in the absence of standard markers of disease progression. Although formal validation of the CDS was not possible due to lack of available EDSS in the EMR, the economic burden results align with prior publications and show that healthcare costs increase with increasing disability. Future validation studies of the CDS are warranted.

Comparison of diagnosis and prescribing practices between virtual visits and office visits for adults diagnosed with uncomplicated urinary tract infections within a primary care network.

OBJECTIVES: Telemedicine visits are an increasingly popular method of care for mild infectious complaints, including uncomplicated urinary tract infections (UTIs), and they are an important target for antimicrobial stewardship programs (ASPs) to evaluate quality of prescribing. In this study, we compared antimicrobial prescribing in a primary care network for uncomplicated UTIs treated through virtual visits and at in-office visits. DESIGN: Retrospective cohort study comparing guideline-concordant antibiotic prescribing for uncomplicated UTI between virtual visits and office visits. SETTING: Primary care network composed of 44 outpatient sites and a single virtual visit platform. PATIENTS: Adult female patients diagnosed with a UTI between January 1 and December 31, 2018. METHODS: Virtual visit prescribing was compared to office visit prescribing, including agent, duration, and patient outcomes. The health system ASP provides annual education to all outpatient providers regarding local antibiogram trends and prescribing guidelines. Guideline-concordant therapy was assessed based on the network's ASP guidelines. RESULTS: In total, 350 patients were included, with 175 per group. Patients treated for a UTI through a virtual visit were more likely to receive a first-line antibiotic agent (74.9% vs 59.4%; P = .002) and guideline-concordant duration (100% vs 53.1%; P < .001). Patients treated through virtual visits were also less likely to have a urinalysis (0% vs 97.1%; P < .001) or urine culture (0% vs 73.1%; P < .001) ordered and were less likely to revisit within 7 days (5.1% vs 18.9%; P < .001). CONCLUSIONS: UTI care through a virtual visit was associated with more appropriate antimicrobial prescribing compared to office visits and decreased utilization of diagnostic and follow-up resources.

Managing COVID-19 in Renal Transplant Recipients: A Review of Recent Literature and Case Supporting Corticosteroid-sparing Immunosuppression.

Novel coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome virus (SARS-CoV-2) has become a global health care crisis. The Centers for Disease Control and Prevention (CDC) lists immunocompromised patients, including those requiring immunosuppression following renal transplantation, as high risk for severe disease from SARS-CoV-2. Treatment for other viral infections in renal transplant recipients often includes a reduction in immunosuppression; however, no current guidelines are available recommending the optimal approach to managing immunosuppression in the patients who are infected with SARS-CoV-2. It is currently advised to avoid corticosteroids in the treatment of SARS-CoV-2 outside of critically ill patients. Recently published cases describing inpatient care of COVID-19 in renal transplant recipients differ widely in disease severity, time from transplantation, baseline immunosuppressive therapy, and the modifications made to immunosuppression during COVID-19 treatment. This review summarizes and compares inpatient immunosuppressant management strategies of recently published reports in the renal transplant population infected with SARS-CoV-2 and discusses the limitations of corticosteroids in managing immunosuppression in this patient population.

Comparison of Diagnosis and Prescribing Practices Between Virtual Visits and Office Visits for Adults Diagnosed With Sinusitis Within a Primary Care Network.

BACKGROUND: Many antibiotics prescribed in the outpatient setting result from upper respiratory tract infections (URTIs); however, these infections are often viral. Virtual visits have emerged as a popular alternative to office visits for URTIs and may be an important target for antimicrobial stewardship programs. METHODS: This retrospective cohort study evaluated adult patients diagnosed with sinusitis treated within a single primary care network. The primary objective was to compare guideline-concordant diagnosis between patients treated via virtual visits vs in-office visits. Guideline-concordant bacterial sinusitis diagnosis was based on national guideline recommendations. Secondary objectives included comparing guideline-concordant antibiotic prescribing between groups and 24-hour, 7-day, and 30-day revisits. RESULTS: A total of 350 patients were included in the study, with 175 in each group. Patients treated for sinusitis were more likely to receive a guideline-concordant diagnosis in the virtual visit group (69.1% vs 45.7%; P < .001). Additionally, patients who completed virtual visits were less likely to receive antibiotics (68.6% vs 94.3%; P < .001). Guideline-concordant antibiotic selection was similar between groups (67.5% vs 64.8%; P = .641). The median duration of therapy in both groups was 10 days (P = .88). Patients completing virtual visits were more likely to revisit for sinusitis within 24 hours (8% vs 1.7%; P = .006) and within 30 days (14.9% vs 7.4%; P = .027). CONCLUSIONS: In adult patients presenting with sinusitis, care at a virtual visit was associated with an increase in guideline-concordant diagnosis and a decrease in antibiotic prescribing compared with in-office primary care visits. Virtual visit platforms may be a valuable tool for antimicrobial stewardship programs in the outpatient setting.

Real-World Adherence and Persistence to Oral Disease-Modifying Therapies in Multiple Sclerosis Patients Over 1 Year.

BACKGROUND: Disease-modifying therapies (DMTs) are indicated to reduce relapse rates and slow disease progression for relapsing-remitting multiple sclerosis (MS) patients when taken as prescribed. Nonadherence or non-persistence in the real-world setting can lead to greater risk for negative clinical outcomes. Although previous research has demonstrated greater adherence and persistence to oral DMTs compared with injectable DMTs, comparisons among oral DMTs are lacking. OBJECTIVE: To compare adherence, persistence, and time to discontinuation among MS patients newly prescribed the oral DMTs fingolimod, dimethyl fumarate, or teriflunomide. METHODS: This retrospective study used MarketScan Commercial and Medicare Supplemental claims databases. MS patients with ≥ 1 claim for specified DMTs from April 1, 2013, to June 30, 2013, were identified. The index drug was defined as the first oral DMT within this period. To capture patients newly initiating index DMTs, patients could not have a claim for their index drugs in the previous 12 months. Baseline characteristics were described for patients in each treatment cohort. Adherence, as measured by medication possession ratio (MPR) and proportion of days covered (PDC); persistence (30-day gap allowed); and time to discontinuation over a 12-month follow-up period were compared across treatment cohorts. Adjusted logistic regression models were used to examine adherence, and Cox regression models estimated risk of discontinuation. RESULTS: 1,498 patients newly initiated oral DMTs and met study inclusion criteria: fingolimod (n = 185), dimethyl fumarate (n = 1,160), and teriflunomide (n = 143). Patients were similar across most baseline characteristics, including region, relapse history, and health care resource utilization. Statistically significant differences were observed across the treatment cohorts for age, gender, previous injectable/infused DMT use, and comorbidities. Adherence and time to discontinuation were adjusted for age, gender, region, previous oral and injectable/infused DMT use, relapse history, and Charlson Comorbidity Index score. Relative to fingolimod patients, dimethyl fumarate and teriflunomide patients were significantly less likely to have an MPR ≥ 80% (OR = 0.18; 95% CI = 0.09-0.36; P < 0.001 and OR = 0.19; 95% CI = 0.08-0.42; P < 0.001, respectively). Similarly, relative to fingolimod patients, dimethyl fumarate and teriflunomide patients were significantly less likely to have PDC ≥ 80% (OR = 0.47; 95% CI = 0.33-0.67; P < 0.001 and OR = 0.37; 95% CI = 0.23-0.59; P < 0.001, respectively). Additionally, the HR for discontinuation was about 2 times greater for dimethyl fumarate (HR = 1.93; 95% CI = 1.44-2.59; P < 0.001) and teriflunomide patients (HR = 2.27; 95% CI = 1.57-3.28; P < 0.001) compared with fingolimod. CONCLUSIONS: In a real-world setting, patients taking fingolimod had better adherence and persistence compared with patients taking other oral DMTs over 12 months. Coupled with clinical factors, medication adherence and persistence should be important considerations when determining coverage decisions for MS patients.

Evidence to Support Montgomery-Asberg Depression Rating Scale Administration Every 24 Hours to Assess Rapid Onset of Treatment Response.

OBJECTIVE: This study investigated the suitability of the Montgomery-Asberg Depression Rating Scale (MADRS), with a 24-hour recall period (MADRS-24hr), to assess the rapid onset of the antidepressant effect of a treatment in patients with treatment-resistant depression (TRD). Psychometric properties of the MADRS-24hr were assessed together with qualitative assessment of content validity. METHODS: Content validity was assessed using semistructured interviews conducted from November 2013 to December 2013 in patients (18-64 years old) with TRD who met DSM-IV diagnostic criteria and health care professionals (HCPs) experienced in treating major depressive disorder and familiar with using the MADRS. The psychometric properties of MADRS-24hr were evaluated using data from 2 randomized clinical studies involving patients with TRD. RESULTS: A total of 23 patients (15 [65%] women) with TRD (mean age = 45 years) and 11 HCPs were interviewed. With the exception of reduced sleep, the majority of patients and HCPs reported that the items captured in the MADRS can fluctuate in a 24-hour period. The majority of participants also reported that a meaningful change in depression symptoms could be assessed in a 24-hour recall period, except for reduced sleep and appetite. Assessment of the psychometric properties of the MADRS-24hr showed that this instrument had high internal consistency reliability (Cronbach α of 0.84 and 0.91) and test-retest reliability (intraclass correlation coefficients of 0.96 and 0.91), had construct validity, and was responsive to change following an intervention. CONCLUSIONS: Overall, results suggest that MADRS-24hr can be used to assess the rapid onset of antidepressant efficacy of a treatment in patients with TRD. TRIAL REGISTRATION: ClinicalTrials.gov identifiers: NCT01627782 and NCT01640080.

Healthcare utilization and cost of pneumococcal disease in the United States.

BACKGROUND: Streptococcus pneumoniae continues to cause a variety of common clinical syndromes, despite vaccination programs for both adults and children. The total U.S. burden of pneumococcal disease is unknown. METHODS: We constructed a decision tree-based model to estimate U.S. healthcare utilization and costs of pneumococcal disease in 2004. Data were obtained from the 2004-2005 National (Hospital) Ambulatory Medical Care Surveys (outpatient visits, antibiotics) and the National Hospital Discharge Survey (hospitalization rates), and CDC surveillance data. Other assumptions regarding the incidence of each syndrome due to pneumococcus, expected health outcomes, and healthcare utilization were derived from literature and expert opinion. Healthcare and time costs used 2007 dollars. RESULTS: We estimate that, in 2004, pneumococcal disease caused 4.0 million illness episodes, 22,000 deaths, 445,000 hospitalizations, 774,000 emergency department visits, 5.0 million outpatient visits, and 4.1 million outpatient antibiotic prescriptions. Direct medical costs totaled $3.5 billion. Pneumonia (866,000 cases) accounted for 22% of all cases and 72% of pneumococcal costs. In contrast, acute otitis media and sinusitis (1.5 million cases each) comprised 75% of cases but only 16% of direct medical costs. Patients ≥ 65 years old, accounted for most serious cases and the majority of direct medical costs ($1.8 billion in healthcare costs annually). In this age group, pneumonia caused 242,000 hospitalizations, 1.4 million hospital days, 194,000 emergency department visits, 374,000 outpatient visits, and 16,000 deaths. However, if work loss and productivity are considered, the cost of pneumococcal disease among younger working adults (18-<50) nearly equaled those ≥ 65. CONCLUSIONS: Pneumococcal disease remains a substantial cause of morbidity and mortality even in the era of routine pediatric and adult vaccination. Continued efforts are warranted to reduce serious pneumococcal disease, especially adult pneumonia.

Antimicrobial resistance trends of Shigella serotypes in New York City, 2006-2009.

Shigellosis is the third most common enteric bacterial infection in the United States. Although infection is typically self-limiting, empiric treatment is often prescribed. Because of increasing antimicrobial resistance to Shigella, empiric treatment options are decreasing. Identifying resistance patterns can inform empiric treatment recommendations. The goals of our study were to examine risk factors associated with antimicrobial resistance of Shigella and examine issues related to empiric treatment and antimicrobial resistance of Shigella. During June 2006-February 2009, we attempted to interview all New York City patients reported to have shigellosis. Their Shigella isolates were tested for antimicrobial susceptibility to examine the level of resistance and identify risk factors for resistance. Analysis was conducted on two groups distinguished by a large outbreak that was documented during the data collection period. Of the 477 nonoutbreak patients, 333 (70%) patients reported taking an antibiotic for shigellosis and 36 (11%) were treated with an antibiotic to which their Shigella infection was resistant. Among this group, high levels of antimicrobial resistance were detected to amoxicillin-clavulanate (66%), ampicillin (68%), and trimethoprim-sulfamethoxazole (66%). Non-travel-associated ciprofloxacin-resistant Shigella (five patients) and ciprofloxacin-resistant Shigella sonnei (four patients) were reported for the first time to our knowledge. Antimicrobial resistance is significantly higher in New York City residents compared with national data. Some patients were treated with therapies that were not effective and to which the patient's Shigella infection was resistant. Shigella infections should not be treated with antibiotics unless the patient presents with severe or underlying illness and is at risk for systemic illness. When treatment is indicated, local monitoring of Shigella for antimicrobial resistance will provide local clinicians with the best guidance for effective empiric treatments.
