The Core Competencies in Hospital Medicine-Clinical Conditions 2023 Update Methodology.

As hospital medicine continues to evolve, the Society of Hospital Medicine (SHM) recognizes the importance of periodic re-evaluation and adaptation of The Core Competencies in Hospital Medicine to reflect and guide the continual expansion of hospitalists' scope of practice. Since its first publication in 2006, the Core Competencies were last revised in 2017 to reflect existing practice. The Core Competencies were initially developed to describe hospitalists' roles and expectations and identify growth opportunities. As hospital medicine has expanded, SHM seeks to maintain the Core Competencies as a framework to guide curricular development, enhance practice assessment, improve the quality of care, and cultivate systems-based practices. Additionally, it helps elucidate the clinical and systems-based aspects central to the field. Thus, the new chapters in the 2023 clinical conditions update focus on enhancing individual hospitalist practice in evaluating and managing common clinical conditions. The accompanying article describes the chapter review and revision process and the criteria for new chapter selection.

Impact of Bedside Rounding on Attending Teaching Evaluations.

OBJECTIVE: To examine associations between bedside rounding (BSR) and other rounding strategies (ORS) with resident evaluations of teaching attendings and self-reported attending characteristics. METHODS: Faculty from three academic medical centers who attended resident teaching services for ≥4 weeks during the 2018-2019 academic year were invited to complete a survey about personal and rounding characteristics. The survey instrument was iteratively developed to assess rounding strategy as well as factors that could affect choosing one rounding strategy over another. Survey results and teaching evaluation scores were linked, then deidentified and analyzed in aggregate. Included evaluation items assessed resident perceptions of autonomy, time management, professionalism, and teaching effectiveness, as well as a composite score (the numeric average of each attending's scores for all of the items at his or her institution). BSR was defined as spending >50% of rounding time in patients' rooms with the team. Hallway rounding and conference room rounding were combined into the ORS category and defined as >50% of rounding time in these settings. All of the scores were normalized to a 10-point scale to allow aggregation across sites. RESULTS: A total of 105 attendings were invited to participate, and 65 (62%) completed the survey. None of the resident evaluation scores significantly differed based on rounding strategy. Composite scores were similar for BSR and ORS (difference of <0.1 on a 10-point scale). Spearman correlation coefficients identified no statistically significant correlation between rounding strategy and evaluation scores. An exploratory analysis of variance model identified no single factor that was significantly associated with composite teaching scores (P > 0.45 for all) or the domains of teaching efficacy, professionalism, or autonomy (P > 0.13 for all). Having a formal educational role was significantly associated with better evaluation scores for time management, and the number of lectures delivered per year approached statistical significance for the same domain. CONCLUSIONS: Conducting BSR did not significantly affect resident evaluations of teaching attendings. Resident perception of teaching effectiveness based on rounding strategy should be neither a motivator nor a barrier to widespread institution of BSR.

Emergence of KPC-possessing Klebsiella pneumoniae in Brooklyn, New York: epidemiology and recommendations for detection.

Among 257 isolates of Klebsiella pneumoniae collected in Brooklyn, NY, 24% were found to possess bla(KPC). Clinical microbiology laboratories that used automated broth microdilution systems reported 15% of the KPC-possessing isolates as susceptible to imipenem. The imipenem MIC was found to be markedly affected by the inoculum. For accurate detection of KPC-possessing K. pneumoniae, particular attention should be paid to proper inoculum preparation for broth-based susceptibility methods. In addition, using ertapenem or meropenem for class reporting of carbapenem susceptibility will improve detection.

Carbapenemase-producing Klebsiella pneumoniae in Brooklyn, NY: molecular epidemiology and in vitro activity of polymyxin B and other agents.

OBJECTIVES: To describe the molecular epidemiology of carbapenem-resistant Klebsiella pneumoniae in Brooklyn, NY and assess the in vitro activity of various antibiotic combinations. METHODS: Clinical isolates with suspected carbapenem resistance were referred to the central research laboratory from August 2003 to June 2004. Isolates underwent MIC testing, ribotyping, and were analysed for the presence of KPC carbapenemases. Time-kill studies using various antibiotic(s) were performed on selected isolates. RESULTS: Ninety-six isolates were referred from 10 Brooklyn hospitals. All isolates were resistant to the carbapenems with most having MICs >32 mg/L. Few were susceptible to fluoroquinolones and cephalosporins; approximately half were susceptible to aminoglycosides, and 90% to polymyxin B. Two-thirds were susceptible to doxycycline, and all were considered susceptible to the investigational glycylcycline antibiotic tigecycline. Virtually all possessed bla(KPC), and over 80% belonged to one ribotype. In time-kill studies involving 16 isolates, tigecycline demonstrated bacteriostatic activity and polymyxin B concentration-dependent bactericidal activity. The combination of polymyxin B at 0.5 x MIC plus rifampicin had synergic activity against 15/16 isolates, including two polymyxin-resistant strains. The combination of polymyxin B plus imipenem had synergic bactericidal activity against 10/16 isolates, but was antagonistic for three isolates. CONCLUSIONS: Multiresistant K. pneumoniae with bla(KPC) are present in multiple hospitals in New York City. The most consistently active agents in vitro were tigecycline and polymyxin B, particularly when the latter was combined with rifampicin. The clinical efficacy of these agents remains to be determined.
