Abstract
Objective The novel coronavirus disease 2019 (COVID-19) pandemic has spread worldwide, and hospitals in Japan have been forced to respond to the situation. This study evaluated the broad-spectrum antimicrobial use before and during the COVID-19 pandemic in an acute tertiary-care hospital. Methods This single-center, retrospective study was conducted between January 2019 and June 2021. Patients We reviewed patients treated with three broad-spectrum antipseudomonal agents: carbapenems, tazobactam/piperacillin, and cefepime. Monthly aggregated hospital antimicrobial consumption was measured as days of therapy (DOTs) per 1,000 patient-days, and the monthly incidences of Clostridioides difficile infection (CDI), multidrug-resistant Pseudomonas aeruginosa (MRPA), and carbapenemase-producing Enterobacteriaceae (CPE) were recorded. Results The median monthly carbapenem-DOTs during the pre-pandemic and pandemic era were 8.4 and 8.2 per 1,000 patient-days, respectively. A time-series analysis showed non-significant changes in the level between periods (coefficients: 2.08; 95% confidence interval [CI]: -2.9 to 7.0; p=0.44). No change in the trend of monthly carbapenem-DOTs was observed after intervention. No post-intervention changes in the incidence of MRPA or CPE were observed; however, the trend in the incidence of CDI per 1,000 patient-days significantly differed between the two periods (coefficient: -0.04; 95% CI: -0.07, 0.00; p=0.01), and a downward trend was observed in the monthly CDI incidence during the COVID-19 period. Conclusion The consumption of broad intravenous antimicrobial agents has not changed significantly during the pandemic. We need to maintain the quality of medical care, including antimicrobial stewardship, even in specialized resource-limited facilities during a pandemic.

Abstract
Antimicrobial stewardship programs (ASPs) have the potential to effectively deescalate unnecessary methicillin-resistant Staphylococcus aureus (MRSA) coverage. This review summarizes literature published from 2014 through 2021 describing contemporary ASP methods and their resulting effectiveness at reducing anti-MRSA agent use (ie vancomycin, linezolid, daptomycin, ceftaroline, and clindamycin). This review of the literature examined the following strategies, which had reports of success in either decreasing the use or duration of anti-MRSA agents: prospective review and feedback, antibiotic timeouts, health system or department protocol changes, polymerase chain reaction (PCR) and rapid testing of patient samples. Most of the current literature continue to support most ASP interventions including antibiotic timeouts, pathways, and molecular testing including MRSA nasal PCRs and rapid diagnostic testing can be successful at reducing unnecessary anti-MRSA use.

Abstract
Limited data are available regarding part-time infectious disease consultations (IDCs) and their importance in tertiary care teaching hospitals in Japan. This is a retrospective review of IDCs from June 2016 to March 2021 and describes IDC services provided by part-time infectious disease specialists once a week for 4 hours, and their impact on the quality of medical care, including antimicrobial stewardship. Data, such as the requesting department, requesting reasons, and final diagnoses, were analyzed. In April 2018, part-time infectious disease specialists launched consultation services and attended an antimicrobial stewardship team conference. Meropenem, tazobactam/piperacillin, and cefepime monthly days of therapy (DOT) were calculated to assess the effect of each intervention; a pre-post analysis was conducted using the Kruskal-Wallis test. Additional quality improvement (QI) projects related to infectious diseases were implemented. There were 237 IDCs during the study period. Consultations were mostly requested by the General Internal Medicine, Emergency Medicine, and Cardiology departments. The most common diagnoses were bone/joint, respiratory, and genitourinary infections. Infectious disease services, even on a part-time basis, achieve good outcomes in patient management, antimicrobial stewardship, and QI projects. DOT/1000 patient-days were reduced for meropenem and cefepime, while it increased for tazobactam/piperacillin. The DOT/1000 patient-days for the 3-antipseudomonal agents significantly decreased during this period. After implementing the QI tetanus vaccination project in the Emergency Room, the number of tetanus toxoid vaccinations per month increased.

Abstract
Purpose The general internal medicine (GIM) department can be an effective diagnostic coordinator for undiagnosed outpatients. We investigated the contribution of GIM consultations to the diagnosis of patients admitted to specialty departments in hospitals in Japan that have not yet adopted a hospitalist system. Patients and Methods This single-center, retrospective observational study was conducted at a university hospital in Japan. GIM consultations from other departments on inpatients aged ≥20 years, from April 2016 to March 2021, were included. Data were extracted from electronic medical records, and consultation purposes were categorized into diagnosis, treatment, and diagnosis and treatment. The primary outcome was new diagnosis during hospitalization for patients with consultation purpose of diagnosis or diagnosis and treatment. The secondary outcomes were the purposes of consultation with the Diagnostic and Generalist Medicine department. Results In total, 342 patients were included in the analysis. The purpose of the consultations was diagnosis for 253 patients (74%), treatment for 60 (17.5%), and diagnosis and treatment for 29 patients (8.5%). In 282 consultations for diagnosis and diagnosis and treatment, 179 new diagnoses were established for 162 patients (57.5%, 95% confidence interval [CI], 51.5-63.3). Conclusion The GIM department can function as a diagnostic consultant for inpatients with diagnostic problems admitted to other specialty departments in hospitals where hospitalist or other similar systems are not adopted.

Abstract
In Japan, general internal medicine (GIM) physicians must be aware of frequently encountered infections because of the shortage of infectious disease (ID) specialists. However, there are currently no epidemiological data on this subject. This study aimed to describe the frequency and pattern of ID consultations requested by GIM physicians in Japan. This is a 3-year retrospective review of the ID consultations requested by GIM physicians in Japan at a community-based acute tertiary care teaching hospital in Tokyo from April 2018 to March 2021. Demographic data, such as reasons for consultation, causative organism, and final diagnoses, were collected. During the study period, ID consultations were requested by GIM physicians 128 times. The incidence rates of bacteremia and 30-day mortality were 65.6% (n = 84) and 3.1% (n = 4), respectively. The most common diagnostic classifications after ID consultation were bone/joint (24.2%, n = 31), respiratory (17.7%, n = 22), and cardiovascular infections (12.5%, n = 16). The most common final diagnoses were bacteremia (11.7%, n = 15), infective endocarditis (9.4%, n = 12), and vertebral osteomyelitis (7.8%, n = 10). This is the first study to describe the ID consultation cases requested by GIM physicians in Japan in a community-based acute tertiary care teaching hospital. Despite the shortage of ID specialists, GIM physicians covered a wide range of IDs, including bone/joint infections and infectious endocarditis, which require long-term care. ID and GIM physicians, including hospitalists, should cooperate to promote the quality of care and clinical management. Future multi-center studies with large numbers of clinical cases are needed to determine the ID clinical knowledge required by GIM physicians in Japan.

Koike Y, Nishiura H. Recovery of antimicrobial susceptibility in methicillin-resistant Staphylococcus aureus (MRSA): a retrospective, epidemiological analysis in a secondary care hospital, Sapporo, Japan. PeerJ 2021; 9:e11644.

Abstract
Anti-methicillin-resistant Staphylococcus aureus (MRSA) drugs are critical final options for treating MRSA infection. This study investigated the percentage of all S. aureus isolates that are resistant to methicillin and also MRSA susceptibility to other antimicrobial agents in the JR Sapporo Hospital inpatient service. The inpatient service MRSA percentages for Japan, Hokkaido, and JR Sapporo Hospital from 2010-2019 were compared, exploring the annual rate of change in the MRSA percentage. We also investigated the antimicrobial use density (AUD) and its relationship with MRSA antimicrobial susceptibility in the JR Sapporo Hospital during 2019. The MRSA percentage in JR Sapporo Hospital was 61.5% (95% CI [52.6-69.7]) in 2010 but was only 51.6% (95% CI [41.6-61.5]) in 2019, which is a 1.43% (95% CI [0.42-2.43]) annual decrease (p = 0.05). Regarding the MRSA antimicrobial susceptibility rate in JR Sapporo Hospital, the highest rates of annual increase were seen for minocycline (3.11% (95% CI [2.25-3.94])) followed by fosfomycin (2.85% (95% CI [1.83-3.85])). Positive correlations with the AUD of anti-MRSA drugs were identified for susceptibility to erythromycin (p < 0.01), clindamycin (p = 0.002), and levofloxacin (p = 0.0005). A recovery of MRSA antimicrobial susceptibility was observed in our antibiogram dataset. Our study supports the potential for appropriate antimicrobial agent use in reviving MRSA antimicrobial susceptibility.

Reduction of 30-day death rates from Staphylococcus aureus bacteremia by mandatory infectious diseases consultation: Comparative study interventions with and without an infectious disease specialist. Int J Infect Dis 2020; 103:308-315. [PMID: 33278619 DOI: 10.1016/j.ijid.2020.11.199] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2020] [Revised: 11/12/2020] [Accepted: 11/26/2020] [Indexed: 11/20/2022] Open
Abstract
OBJECTIVES Most Japanese hospitals need to keep to higher Staphylococcus aureus bacteremia (SAB) quality-of-care indicators (QCIs) and create strategies that can maximize the effect of these QCIs with only a small number of infectious disease specialists. This study aimed to evaluate the clinical outcomes of patients with SAB before and after the enhancement of the mandatory infectious disease consultations (IDCs). METHODS This retrospective study was conducted at a tertiary care hospital in Japan. The primary outcome was the 30-day mortality between each period. A generalized structural equation model was employed to examine the effect of the mandatory IDC enhancement on 30-day mortality among patients with SAB. RESULTS A total of 114 patients with SAB were analyzed. The 30-day all-cause mortality differed significantly between the two periods (17.3% vs. 4.8%, P = 0.02). Age, three-QCI point ≥ 1, and Pitt bacteremia score ≥ 3 were the significant risk factors for 30-day mortality. The intervention was also significantly associated with improved adherence to QCIs. CONCLUSION Mandatory IDCs for SAB improved 30-day mortality and adherence to QCIs after the intervention. In Japan, improving the quality of management in patients with SAB should be an important target.
