Purpose: To provide summarization of the most significant infectious diseases (ID) pharmacotherapy articles published in peer-reviewed literature in 2022. Summary: Members of the Houston Infectious Diseases Network (HIDN) nominated notable articles providing significant contributions to ID pharmacotherapy in 2022. Article nominations included those pertaining to general ID, as well as those including coronavirus disease 2019 (COVID-19), and human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) pharmacotherapy. A total of 71 articles were nominated by HIDN. Members: 68 articles pertaining to general ID pharmacotherapy and 3 articles focusing on HIV/AIDS. To aid selection of the most these most notable articles of 2022, a survey was created and distributed to members of the Society of Infectious Diseases Pharmacists (SIDP). Of the 153 SIDP members who participated in the survey, there were 128 recorded votes for the top 10 general ID pharmacotherapy articles and 30 votes recorded for the top HIV/AIDS article. The most notable publications are summarized. Conclusion: Post pandemic significant advances in antimicrobial stewardship and infectious disease states continues to occur in a world recently focused on the coronavirus disease 2019 (COVID-19) global pandemic. Continuous growth in publication of ID-related articles over the past year lends towards the aims of this review to aid clinicians in remaining current on key practice-changing ID pharmacotherapy publications from 2022.

Background: Guidelines support area-under-the-curve (AUC) monitoring for vancomycin dosing which may lower overall doses and reduce acute kidney injury (AKI). Objective: The aim of this study was to compare incidence of AKI across 3 vancomycin dosing modalities: AUC-targeted Bayesian pharmacokinetic software, AUC-targeted empiric dosing nomogram, and trough-guided dosing using clinical pharmacists’ judgment. Methods: This retrospective study included adult patients with a pharmacy dosing consult who received ≥1 dose of vancomycin and ≥1 serum vancomycin level documented between January 1, 2018, and December 31, 2019. Patients with baseline serum creatinine ≥2 mg/dL, weight ≥100 kg, receiving renal replacement therapy, AKI prior to vancomycin therapy, or vancomycin ordered only for surgical prophylaxis were excluded. The primary analysis was incidence of AKI adjusted for baseline serum creatinine, age, and intensive care unit admission. A secondary outcome was adjusted incidence of an abnormal trough value (<10 or >20 μg/mL). Results: The study included 3459 encounters. Incidence of AKI was 21% for Bayesian software (n = 659), 22% for the nomogram (n = 303), and 32% for trough-guided dosing (n = 2497). Compared with trough-guided dosing, incidence of AKI was lower in the Bayesian (adjusted odds ratio [OR] = 0.72, 95% confidence interval [CI]: 0.58-0.89) and the nomogram (adjusted OR = 0.71, 95% CI: 0.53-0.95) groups. Compared with trough-guided dosing, abnormal trough values were less common in the Bayesian group (adjusted OR = 0.83, 95% CI: 0.69-0.98). Conclusion and Relevance: Study results suggest that use of AUC-guided Bayesian software reduces the incidence of AKI and abnormal trough values compared with trough-guided dosing.

OBJECTIVE To assess the impact of Matrix-Assisted Laser Desorption/Ionization Time-of-Flight (MALDI-TOF) mass spectrometry for rapid pathogen identification directly from early-positive blood cultures coupled with an antimicrobial stewardship program (ASP) in two community hospitals. Process measures and outcomes prior and after implementation of MALDI-TOF/ASP were evaluated. DESIGN Multicenter retrospective study. SETTING Two community hospitals in a system setting, Houston Methodist (HM) Sugar Land Hospital (235 beds) or HM Willowbrook Hospital (241 beds). PATIENTS Patients ≥18 years of age with culture-proven Gram-negative bacteremia. INTERVENTION Blood cultures from both hospitals were sent to and processed at our central microbiology laboratory. Clinical pharmacists at respective hospitals were notified of pathogen ID and susceptibility results. RESULTS We evaluated 572 patients for possible inclusion. After pre-defined exclusion criteria, 151 patients were included in the pre-intervention group and 242 were included in the intervention group. After MALDI-TOF/ASP implementation, the mean identification time after culture positivity was significantly reduced from 32 hours (±16 hours) to 6.5 hours (±5.4 hours) (P<.001); mean time to susceptibility results was significantly reduced from 48 (±22) hours to 23 (±14) hours (P<.001); and time to therapy adjustment was significantly reduced from 75 (±59) hours to 30 (±30) hours (P<.001). Mean hospital costs per patient were $3,411 less in the intervention group compared with the pre-intervention group ($18,645 vs $15,234; P=.04). CONCLUSION This study is the first to analyze the impact of MALDI-TOF coupled with an ASP in a community hospital setting. Time to results significantly differed with the use of MALDI-TOF, and time to appropriate therapy was significantly improved with the addition of ASP. Infect. Control Hosp.

PURPOSE:Important articles on topics pertinent to infectious diseases (ID) pharmacotherapy published in prominent peer-reviewed journals in 2010 are summarized.SUMMARY:At the end of 2010, pharmacists, physicians, and researchers in the Houston Infectious Diseases Network were asked to nominate articles published from January through December 2010 that they perceived as having a significant impact in the field of ID pharmacotherapy. The resulting list, comprising 27 articles relating to human immunodeficiency virus (HIV) disease or acquired immune deficiency syndrome (AIDS) and 52 articles on a broad range of other ID-related topics, was sent to members of the Society of Infectious Diseases Pharmacists (SIDP) for evaluation via an Internet survey. The survey participants were asked to select from the list 10 articles unrelated to HIV or AIDS and 1 HIV- or AIDS-related article that in their view had the most significant impact in the field. Of the 380 SIDP members surveyed, 105 (27.6%) ranked the non-HIV-related papers and 45 (11.8%) ranked the HIV-related papers. The 11 highest-ranked publications-including 2 articles presenting updated practice guidelines-are summarized here.CONCLUSION:Due to the increasing number of articles published each year, it is difficult to maintain a current knowledge of significant publications in the field of ID pharmacotherapy. This review of key publications in 2010 may be helpful to the nonspecialist clinician by lessening this burden.

PURPOSESignificant publications on infectious diseases (ID) pharmacotherapy in 2007 were compiled and summarized.SUMMARYOn January 2, 2008, the 21 members of the Houston Infectious Disease Network (HIDN) were asked to select an article that was published in a peer-reviewed journal between January 1 and December 31, 2007, and write a summary highlighting why the article was significant to the diagnosis or treatment of ID. Articles were selected based on prior "top 10" presentations at major ID and pharmacy meetings or were listed as major articles in prominent ID journals. Priority was given to peer-reviewed publications and nationally recognized clinical treatment guidelines. Nineteen articles and summaries were submitted by HIDN members. The publication listing was distributed to Society of Infectious Diseases Pharmacists members via an Internet survey in early February 2008. Members were asked to select the 10 most significant articles relating to ID pharmacotherapy from the list of 19 and were allowed to add an additional article that was not already listed. A total of 102 individuals participated in the survey. A listing of the top 10 articles published in 2007 and one honorable mention was compiled, and the significance of each article was summarized.CONCLUSIONThe increased number of articles in the peer-reviewed medical literature related to the diagnosis and treatment of ID has made it challenging to maintain a contemporary knowledge base of key publications. This summary of significant ID articles published in 2007 can help to alleviate the burden of knowledge management.
