Assessing guideline-concordant prescribing for community-acquired pneumonia.

Background Current reports of outpatient antimicrobial prescribing practices may overestimate guideline concordance since they address only drug selection. Appropriate stewardship should consider all prescribing criteria (i.e., dose, frequency, duration, and route of administration) to fully assess guideline concordance. Objective Using a community-acquired pneumonia (CAP) example, the aims of this pilot study were to estimate guideline concordance in adult patients 18 years or older when all prescribing criteria are considered, and provide recommendations to optimize treatment. Specific objectives were to determine which medications were most commonly prescribed for high-and low-risk patients, respectively, and determine if prescription parameters typically meet guideline recommendations. Methods This historical (retrospective) chart review at a large, non-emergent, outpatient academic practice included adult cases of CAP identified by ICD-9 codes, 481.x-486.x, 480.x and 487.x, diagnosed between July 1, 2014 and June 30, 2015. Patients were stratified into low- or high-risk categories based on presence of comorbidities and recent antibiotic use. Descriptive statistics were used to profile the sample and estimate aggregate guideline appropriateness, based on Infectious Disease Society of America/American Thoracic Society guidelines. Cases that were not prescribed an antibiotic at the index visit were excluded from assessment of concordance. Results Of the 101 total episodes identified, 49% were treated with an antibiotic. Of the 45 cases that met low-risk criteria, seven of the 24 treated cases (29%) received an appropriate antibiotic. When considering all prescription elements, all seven cases were congruent, for a composite concordance rate of 29%. Of the 56 cases that met high-risk criteria, 13 of the 25 treated cases (52%) received an appropriate antibiotic, although two cases were prescribed a suboptimal dose, and one case was prescribed a suboptimal duration, dropping composite concordance to 40%. Overall, prescribing was concordant in 17 of the 49 treated cases (35%). Conclusion Concordance with current guidelines in this local sample is suboptimal. In the low-risk group, when the correct medication was chosen, dose, duration, and frequency were appropriate. Consideration of dose and duration of treatment decreased the rate of concordant prescribing in the high-risk group.

A literacy-sensitive approach to improving antibiotic understanding in a community-based setting.

OBJECTIVE: Antibiotic misuse contributes to antibiotic-resistant bacterial infections. Patient and prescriber knowledge and behaviors influence antibiotic use. Past research has focused on describing and influencing prescriber behavior with less attention to the patient role in antibiotic use. This study seeks to: (1) develop and deploy a program to enhance patient knowledge about antibiotic use; (2) evaluate whether providing patient education is associated with improvements in antibiotic knowledge in a community-based sample; and (3) explore whether health literacy may be associated with knowledge of appropriate antibiotic use. METHOD: This study developed, deployed, and evaluated whether community-based educational seminars enhance patient knowledge about antibiotic use. KEY FINDINGS: Twenty-eight participants from five locations completed the seminar. The antibiotic knowledge index score significantly increased by 2.0 points on the 14 point knowledge index from 10.95 (±2.88) to 12.95 (±1.72) (P = 0.0011) for the 19 participants completing both the pre and post-test. CONCLUSION: A community-based educational seminar on appropriate antibiotic use can effectively increase patient understanding of their role in antibiotic stewardship and combat the inappropriate use of antibiotics.

Treatment Options and Considerations for Intestinal Helminthic Infections.

Objective: To review the literature regarding the epidemiology and treatment of intestinal helminthic infections. Data Sources: A literature search of MEDLINE (1946-January 2014), EMBASE (1980-January 2014), International Pharmaceutical Abstracts (1970-January 2014), and the Cochrane Library (1996-January 2014) was performed using the following terms: intestinal, helminthic, humans, United States, and individual drug names (albendazole, ivermectin, mebendazole, nitazoxanide, praziquantel, pyrantel pamoate). Secondary and tertiary references were obtained by reviewing related articles. Study Selection and Data Extraction: All English-language articles identified from the data sources and clinical studies using anthelmintic agents were included. Data Synthesis: The 2011 removal and continued absence of mebendazole from the market has left limited options for helminth infections. For hookworm, albendazole has a 72% cure rate compared to 32% for pyrantel pamoate. Albendazole, ivermectin, and nitazoxanide appear to be effective for Ascaris with cure rates of 88%, 100%, and 91%, respectively. Both albendazole and pyrantel pamoate have been evaluated for pinworm with cure rates of 94.1% and 96.3%, respectively. Combination therapy with ivermectin and albendazole produces cure rates of 38% to 80% for whipworm. For Strongyloides stercoralis, ivermectin cure rates are 93.1% to 96.8% compared with 63.3% for albendazole. Praziquantel is effective for intestinal trematode infections with cure rates of 97% to 100% while its efficacy against tapeworm ranges from 75% to 85%. Conclusions: Albendazole is the drug of choice for hookworm, Ascaris lumbricoides, and pinworm. In combination with ivermectin, it is the first-line agent for whipworm. Ivermectin is preferred for Strongyloides stercoralis, and praziquantel is effective against most nematodes and trematodes.

Cardiovascular disease and non-steroidal anti-inflammatory drug prescribing in the midst of evolving guidelines.

RATIONALE, AIMS AND OBJECTIVES: Responding to safety concerns, the American Heart Association (AHA) published guidelines for non-steroidal anti-inflammatory drug (NSAID) use in patients with pre-existing cardiovascular disease (CVD) during 2005 and revised them in 2007. In the revision, a stepped approach to pain management recommended non-selective NSAIDs over highly selective NSAIDs. This research evaluated NSAID prescribing during and after guideline dissemination. METHOD: A cross-sectional sample of 8666 adult, community-based practice visits with one NSAID prescription representing approximately 305 million visits from the National Ambulatory Medical Care Survey (NAMCS) from 2005 to 2010 was studied. Multivariable logistic regression controlling for patient, provider and visit characteristics assessed the associations between diagnosis of CVD and NSAID type prescribed during each calendar year. Visits were stratified by arthritis diagnosis to model short-term/intermittent and long-term NSAID use. RESULTS: Approximately one-third (36.8%) of visits involving a NSAID prescription included at least one of four diagnoses for CVD (i.e. hypertension, congestive heart failure, ischaemic heart disease or cerebrovascular disease). Visits involving a CVD diagnosis had increased odds of a prescription for celecoxib, a highly selective NSAIDs, overall [adjusted odds ratio (AOR) = 1.29, 95% confidence interval (CI): 1.06-1.57] and in the subgroup of visits without an arthritis diagnosis (AOR = 1.45, 95% CI: 1.11-1.89). Results were not statistically significant for visits with an arthritis diagnosis (AOR = 1.10, 95% CI: 0.47-2.57). When analysed by year, the relationship was statistically significant in 2005 and 2006, but not statistically significant in each subsequent year. CONCLUSION: National prescribing trends suggest partial implementation of AHA guidelines for NSAID prescribing in CVD from 2005 to 2010.

Pseudomonas aeruginosa bloodstream infection: importance of appropriate initial antimicrobial treatment.

Pseudomonas aeruginosa bloodstream infection is a serious infection with significant patient mortality and health-care costs. Nevertheless, the relationship between initial appropriate antimicrobial treatment and clinical outcomes is not well established. This study was a retrospective cohort analysis employing automated patient medical records and the pharmacy database at Barnes-Jewish Hospital. Three hundred five patients with P. aeruginosa bloodstream infection were identified over a 6-year period (January 1997 through December 2002). Sixty-four (21.0%) patients died during hospitalization. Hospital mortality was statistically greater for patients receiving inappropriate initial antimicrobial treatment (n = 75) compared to appropriate initial treatment (n = 230) (30.7% versus 17.8%; P = 0.018). Multiple logistic regression analysis identified inappropriate initial antimicrobial treatment (adjusted odds ratio [AOR], 2.04; 95% confidence interval [CI], 1.42 to 2.92; P = 0.048), respiratory failure (AOR, 5.18; 95% CI, 3.30 to 8.13; P < 0.001), and circulatory shock (AOR, 4.00; 95% CI, 2.71 to 5.91; P < 0.001) as independent determinants of hospital mortality. Appropriate initial antimicrobial treatment was administered statistically more often among patients receiving empirical combination antimicrobial treatment for gram-negative bacteria compared to empirical monotherapy (79.4% versus 65.5%; P = 0.011). Inappropriate initial empirical antimicrobial treatment is associated with greater hospital mortality among patients with P. aeruginosa bloodstream infection. Inappropriate antimicrobial treatment of P. aeruginosa bloodstream infections may be minimized by increased use of combination antimicrobial treatment until susceptibility results become known.
