Resilience, self-efficacy and diabetes distress on self-management behaviours in patients newly diagnosed with type 2 diabetes: A moderated mediation analysis.

AIM: To examine (1) the mediating role of self-efficacy between resilience and self-management behaviours and (2) the moderating role of diabetes distress on the relationship between self-efficacy and self-management behaviours in patients newly diagnosed with type 2 diabetes. DESIGN: Cross-sectional design. METHODS: Totally, 195 patients newly diagnosed with type 2 diabetes for more than 5 months but less than 18 months were recruited from three endocrine clinics in Taiwan through convenience sampling. Self-reported questionnaires including demographic and disease characteristics, resilience, self-efficacy and self-management behaviours were used to collect data from October 2020 to May 2021. Moderated mediation analysis was performed by Hayes's PROCESS macro. RESULT: According to bootstrapping results, the indirect effect of resilience on self-management was significant, although the direct effect of resilience on self-management was not. Participants were categorized into with and without diabetes distress groups. The results of moderated mediation analysis indicated self-efficacy significantly correlated with self-management behaviours in participants without diabetes distress, although self-efficacy did not significantly correlate with self-management in participants with diabetes distress. CONCLUSION: The association of resilience with self-management behaviours was fully mediated through self-efficacy with diabetes distress moderating the relationship between self-efficacy and self-management behaviours in patients newly diagnosed with type 2 diabetes. IMPACT: Improving resilience could enhance self-efficacy leading to possible improvement in self-management behaviour, although improving self-efficacy might not benefit self-management behaviours for those with high levels of diabetes distress. Healthcare providers need to first assess and address the diabetes distress before intervening to improve self-efficacy to enhance self-management behaviours in patients newly diagnosed with type 2 diabetes. PATIENT OR PUBLIC CONTRIBUTION: When designing this study, two patients newly diagnosed with diabetes were consulted about the importance of self-management behaviours for them personally.

Mediation Effect of Musculoskeletal Pain on Burnout: Sex-Related Differences.

Burnout occurs when people are exposed to emotionally demanding work situations over an extended period, resulting in physical, emotional, and mental exhaustion. This study adopted the personal burnout (PB) and work-related burnout (WB) scales of the Copenhagen Burnout Inventory to measure burnout levels. Musculoskeletal (MS) pain is one factor influencing burnout. Previous studies have demonstrated that male and female hormones may contribute to sex-related differences in MS pain. This was an observational and cross-sectional study conducted at a medical-university-affiliated hospital in Taichung, Taiwan, in 2021. Data were collected for demographic characteristics, family structure, living habits, occupation, physical health, Nordic Musculoskeletal Questionnaire score, and Copenhagen Burnout Inventory score. Of the 2531 questionnaires that were distributed, 1615 (63.81%) valid questionnaires remained after those with missing data were excluded. The results demonstrated neck and shoulder pain (NBSP) is commonly associated with burnout among healthcare workers, with a higher prevalence among women than among men. With confounders being controlled for, women were found to experience substantially higher levels of personal and work-related burnout than men did. NBSP is a mediating factor; therefore, it is a key reason why women are more likely than men to experience burnout.

Diabetes Mellitus and Heart Failure.

The coexistence of diabetes mellitus (DM) and heart failure (HF) is frequent and is associated with a higher risk of hospitalization for HF and all-cause and cardiovascular mortality. It has been estimated that millions of people are affected by HF and DM, and the prevalence of both conditions has increased over time. Concomitant HF and diabetes confer a worse prognosis than each alone; therefore, managing DM care is critical for preventing HF. This article reviews the prevalence of HF and diabetes and the correlated prognosis as well as provides a basic understanding of diabetic cardiomyopathy, including its pathophysiology, focusing on the relationship between DM and HF with a preserved ejection fraction and summarizes the potential aldosterone and the mineralocorticoid receptor antagonists approaches for managing heart failure and DM. Sodium-glucose cotransporter 2 inhibitors (SGLT2Is) are an emerging class of glucose-lowering drugs, and the role of SGLT2Is in DM patients with HF was reviewed to establish updated and comprehensive concepts for improving optimal medical care in clinical practice.

Association between Antimicrobial Consumption and the Prevalence of Nosocomial Carbapenem-Resistant Escherichia coli and Klebsiella pneumoniae in a Tertiary Hospital in Northern Taiwan.

Carbapenem-resistant Enterobacteriales has become a threat in Taiwan. This is the first local study focusing on the association between carbapenem-resistant Enterobacteriales and antimicrobial consumption. From January 2012 to December 2020, data were collected in a tertiary care hospital in Taipei, Taiwan. Antimicrobial consumption was estimated by the defined daily dose/1,000 patient-days. During the same period, the prevalence of carbapenem-resistant Escherichia coli (CREC) and carbapenem-resistant Klebsiella pneumoniae (CRKP) were collected through routine surveillance data. The following retrospective analyses were conducted: 1) analysis of antimicrobial consumption over time, (2) analysis and forecast of CREC and CRKP prevalence over time, and 3) analysis of correlation between antimicrobial consumption and the prevalence of CREC and CRKP. The consumption of piperacillin/tazobactam (ß = 0.615), fluoroquinolones (ß = 0.856), meropenem (ß = 0.819), and doripenem (ß = 0.891) increased during the observation period (P < 0.001), and the consumption of aminoglycosides (ß = -0.852) and imipenem/cilastatin (ß = -0.851) decreased (P < 0.001). The prevalence of CRKP rose over time (ß = 0.522, P = 0.001) and correlated positively with the consumption of fluoroquinolones, levofloxacin, penicillin/ß-lactamase inhibitor, piperacillin/tazobactam, meropenem, and doripenem (P < 0.05). The prevalence of CRKP and CREC both correlated negatively with consumption of aminoglycosides (P < 0.01). The prevalence of CRKP in our hospital increased as the forecast predicted based on an autoregressive integrated moving average model. This study provides alarming messages for members participating in antimicrobial stewardship programs, including the increasing prevalence of CRKP, the increasing consumption of broad-spectrum antibiotics, and the positive correlation between them.

In vitro activity of cefiderocol, cefepime/enmetazobactam, cefepime/zidebactam, eravacycline, omadacycline, and other comparative agents against carbapenem-non-susceptible Pseudomonas aeruginosa and Acinetobacter baumannii isolates associated from bloodstream infection in Taiwan between 2018-2020.

BACKGROUND/PURPOSE: This study aimed to investigate the in vitro susceptibilities of carbapenem-non-susceptible Pseudomonas aeruginosa (CNSPA) and Acinetobacter baumannii (CNSAB) isolates to cefiderocol, novel ß-lactamase inhibitor (BLI) combinations, new tetracycline analogues, and other comparative antibiotics. METHODS: In total, 405 non-duplicate bacteremic CNSPA (n = 150) and CNSAB (n = 255) isolates were collected from 16 hospitals in Taiwan between 2018 and 2020. Minimum inhibitory concentrations (MICs) were determined using the broth microdilution method, and susceptibilities were interpreted according to the relevant guidelines or in accordance with results of previous studies and non-species-related pharmacokinetic/pharmacodynamic data. RESULTS: Among the isolates tested, cefiderocol demonstrated potent in vitro activity against CNSPA (MIC50/90, 0.25/1 mg/L; 100% of isolates were inhibited at ≤4 mg/L) and CNSAB (MIC50/90, 0.5/2 mg/L; 94.9% of isolates were inhibited at ≤4 mg/L) isolates. More than 80% of CNSPA isolates were susceptible to cefiderocol, ceftazidime/avibactam, ceftolozane/tazobactam, and amikacin, based on breakpoints established by the Clinical and Laboratory Standards Institute. Activities of new BLI combinations varied significantly. Tetracycline analogues, including tigecycline (MIC50/90, 1/2 mg/L; 92.5% of CNSAB isolates were inhibited at ≤2 mg/L) and eravacycline (MIC50/90, 0.5/1 mg/L; 99.6% of CNSAB isolates were inhibited at ≤2 mg/L) exhibited more potent in vitro activity against CNSAB than omadacycline (MIC50/90, 4/8 mg/L). CONCLUSIONS: The spread of CNSPA and CNSAB poses a major challenge to global health. Significant resistance be developed even before a novel agent becomes commercially available. The development of on-site antimicrobial susceptibility tests for these novel agents is of great clinical importance.

Nationwide surveillance of antimicrobial resistance in invasive isolates of Streptococcus pneumoniae in Taiwan from 2017 to 2019.

BACKGROUND/PURPOSE: Streptococcus pneumoniae causes pneumonia and other invasive diseases, and is a leading cause of mortality in the elderly population. The present study aimed to provide current antimicrobial resistance and epidemiological profiles of S. pneumoniae infections in Taiwan. METHODS: A total of 252 nonduplicate S. pneumoniae isolates were collected from patients admitted to 16 hospitals in Taiwan between January 2017 and December 2019, and were analyzed. The minimum inhibitory concentration of antibiotics was determined using the Vitek 2 automated system for antimicrobial susceptibility testing. Furthermore, epidemiological profiles of S. pneumoniae infections were analyzed. RESULTS: Among the strains analyzed, 88% were recognized as invasive pneumococcal strains. According to the Clinical and Laboratory Standards Institute criteria for non-meningitis, the prevalence of penicillin-non-susceptible S. pneumoniae demonstrated a declining trend from 43.6% in 2017 to 17.2% in 2019. However, the rate of penicillin-non-susceptible S. pneumoniae was 85.7% based on the criteria for meningitis. Furthermore, the prevalence of ceftriaxone-non-susceptible S. pneumoniae was 62.7% based on the criteria for meningitis. Isolates demonstrated higher susceptibility toward doripenem and ertapenem than toward meropenem and imipenem. An increased rate of non-susceptibility toward levofloxacin was observed in southern Taiwan (15.1%) and elderly patients (≥65 years; 11.4%). Most isolates were susceptible to vancomycin and linezolid. CONCLUSION: Empirical treatment with ceftriaxone monotherapy for pneumococcal meningitis should be carefully monitored owing to its high non-susceptibility rate. The susceptibility rates of most isolates to penicillin (used for treating non-meningitis pneumococcal diseases), carbapenems (ertapenem and doripenem), respiratory quinolones (moxifloxacin and levofloxacin), vancomycin, and linezolid suggested the potential of these antibiotics in treating pneumococcal diseases in Taiwan.

National surveillance of antimicrobial susceptibilities to dalbavancin, telavancin, tedizolid, eravacycline, omadacycline and other comparator antibiotics and serotype distribution of invasive Streptococcus pneumoniae isolates in adults: results from the Surveillance of Multicenter Antimicrobial Resistance in Taiwan (SMART) programme in 2017-2020.

OBJECTIVES: The aim of this study was to investigate the trends in serotypes and in vitro antimicrobial susceptibility of Streptococcus pneumoniae causing adult invasive pneumococcal disease (IPD) to dalbavancin, telavancin, tedizolid, eravacycline, omadacycline and other comparator antibiotics from 2017-2020 following implementation of the 13-valent pneumococcal conjugate vaccine (PCV-13) and during the COVID-19 (coronavirus disease 2019) pandemic. METHODS: During the study period, 237 S. pneumoniae isolates were collected from non-duplicate patients, covering 15.0% of IPD cases in Taiwan. Antimicrobial susceptibility testing was performed using a Sensititre® system. A latex agglutination method (ImmuLex™ Pneumotest Kit) was used to determine serotypes. RESULTS: Susceptibility rates were high for vancomycin (100%), teicoplanin (100%) and linezolid (100%), followed by ceftaroline (non-meningitis) (98.3%), moxifloxacin (94.9%) and quinupristin/dalfopristin (89.9%). MIC50 and MIC90 values of dalbavancin, telavancin, tedizolid, eravacycline and omadacycline were generally low. Non-vaccine serotype 23A was the leading cause of IPD across the adult age range. Isolates of serotype 15B were slightly fewer than those of PCV-13 serotypes in patients aged ≥65 years. The overall case fatality rate was 15.2% (36/237) but was especially high for non-PCV-13 serotype 15B (21.4%; 3/14). Vaccine coverage was 44.7% for PCV-13 and 49.4% for the 23-valent pneumococcal polysaccharide vaccine (PPSV-23), but was 57% for both PCV-13 and PPSV-23. CONCLUSION: The incidence of IPD was stationary after PCV-13 introduction and only dramatically decreased in the COVID-19 pandemic in 2020. The MIC50 and MIC90 values of dalbavancin, telavancin, tedizolid, eravacycline, omadacycline were generally low for S. pneumoniae causing adult IPD.

In-vitro activity of cefiderocol, cefepime/zidebactam, cefepime/enmetazobactam, omadacycline, eravacycline and other comparative agents against carbapenem-nonsusceptible Enterobacterales: results from the Surveillance of Multicenter Antimicrobial Resistance in Taiwan (SMART) in 2017-2020.

This study examined the susceptibility of carbapenem-nonsusceptible Enterobacterales (CNSE) to cefiderocol, cefepime/zidebactam, cefepime/enmetazobactam, omadacycline, eravacycline and other comparative agents. Non-duplicate Enterobacterales isolates from 16 Taiwanese hospitals were evaluated. Minimum inhibitory concentrations (MICs) were determined using the broth microdilution method, and susceptibility results were interpreted based on relevant guidelines. In total, 201 CNSE isolates were investigated, including 26 Escherichia coli isolates and 175 Klebsiella pneumoniae isolates. Carbapenemase genes were detected in 15.4% (n=4) of E. coli isolates and 47.4% (n=83) of K. pneumoniae isolates, with the most common being blaKPC (79.3%, 69/87), followed by blaOXA-48-like (13.8%, 12/87). Cefiderocol was the most active agent against CNSE; only 3.8% (n=1) of E. coli isolates and 4.6% (n=8) of K. pneumoniae isolates were not susceptible to cefiderocol. Among the carbapenem-resistant E. coli and K. pneumoniae isolates, 88.5% (n=23) and 93.7% (n=164), respectively, were susceptible to ceftazidime/avibactam. For cefepime/zidebactam, 23 (88.5%) E. coli isolates and 155 (88.6%) K. pneumoniae isolates had MICs ≤2/2 mg/L. For cefepime/enmetazobactam, 22 (84.6%) E. coli isolates and 85 (48.6%) K. pneumoniae isolates had MICs ≤2/8 mg/L. The higher MICs of K. pneumoniae against cefepime/enmetazobactam were due to only one (1.5%) of the 67 blaKPC-carrying isolates being susceptible. MICs of omadacycline were significantly higher than those of eravacycline and tigecycline. In summary, cefiderocol, ceftazidime/avibactam and cefepime/zidebactam were more effective against carbapenem-nonsusceptible E. coli and K. pneumoniae than other drugs, highlighting their potential as valuable therapeutics.

Antimicrobial susceptibility of bacteremic vancomycin-resistant Enterococcus faecium to eravacycline, omadacycline, lipoglycopeptides, and other comparator antibiotics: Results from the 2019-2020 Nationwide Surveillance of Multicenter Antimicrobial Resistance in Taiwan (SMART).

Multicenter surveillance of antimicrobial susceptibility was performed for 235 vancomycin-resistant Enterococcus faecium (VREfm) isolates from 18 Taiwanese hospitals. The minimum inhibitory concentrations (MICs) of eravacycline, omadacycline, lipoglycopeptides, and other comparator antibiotics were determined using the broth microdilution method. Nearly all isolates of VREfm were not susceptible to teicoplanin, dalbavancin, and telavancin, with susceptibility rates of 0.5%, 1.7% and 0.5%, respectively. Tigecycline and eravacycline were active against 93.2% and 89.7% of the VREfm isolates, respectively. Moreover, the susceptibility rates of quinupristin/dalfopristin, tedizolid, and linezolid were 59.1%, 84.2%, and 77.4%, respectively. Additionally, 94% of the VREfm isolates were classified as susceptible to daptomycin, and the MICs of omadacycline required to inhibit VREfm growth by 50% and 90% were 0.12 and 0.5 mg/L, respectively. Susceptibility rates of VREfm isolates to synthetic tetracyclines and daptomycin were slightly lower and to oxazolidinone-class antibiotics were much lower in Taiwan than those in other parts of the world. Continuous monitoring of VREfm resistance to novel antibiotics, including synthetic tetracyclines, oxazolidinone-class antibiotics, and daptomycin, is needed in Taiwan.

Risk factors of falls and the gender differences in older adults with diabetes at outpatient clinics.

AIMS: To explore the risk factors of falls and the gender differences based on demographic and disease characteristics, physical capability, and fear of falling in older adults with diabetes visiting outpatient clinics in Taiwan. DESIGN: Cross-sectional design. METHODS: A total of 485 patients with type 2 diabetes aged between 65 and 80 years were recruited from three endocrine outpatient clinics in Taiwan. Demographic and disease characteristics, fall history in the previous one year and fear of falling were collected by a self-reported questionnaire. Calf circumference, handgrip strength, one-leg standing and time up-and-go tests were all performed to assess the physical capability of participants. Data were collected from May 2019 to May 2020. RESULTS: Female gender (OR = 1.75), handgrip strength (OR = 2.43) and fear of falling (OR = 3.38) were important risk factors of falls overall, although fear of falling (OR = 4.69) was the only important risk factor of falls in males, while handgrip strength (OR = 3.48) and fear of falling (OR = 2.86) were important risk factors of falls in females. The sensitivity of simultaneous screening handgrip strength and fear of falling were 85.7, 86.4 and 86.2 in males, females and older adults overall with diabetes, respectively. CONCLUSION: Fear of falling was an important risk factor of falls in both genders, especially in males. Handgrip strength was an important risk factor of falls specifically for females. By simultaneously screening fear of falling and handgrip strength, risk of falls in older adults with diabetes at outpatient clinics could be identified in a more timely manner. Impact Nurses could periodically and simultaneously assess fear of falling and handgrip strength of older adults with diabetes at outpatient clinics. For those are identified at risk of falls on either fear of falling or handgrip strength, nurses could provide corresponding interventions to reduce the fear of falling or improve muscle strength to prevent such falls.

Correlation between Nosocomial Carriage of Vancomycin-Resistant Enterococci and Antimicrobial Use in Taiwan.

A rapid increase of nosocomial vancomycin-resistant enterococci (VRE) from 23.3% in 2009 to 44.5% in 2018 among all the medical centers in Taiwan was found. The aim of the study was to explore the relationship between antimicrobial usage and prevalence of VRE. We conducted the study between January 2010 and December 2019 in a tertiary teaching hospital in Taiwan. Antibiotic consumption was expressed as defined daily doses (DDDs) per 1,000 patient-days (PDs). The trend in antibiotic consumption and VRE prevalence were analyzed by regression analysis with yearly data. Pearson's correlation analysis was used to determine the relationship between antibiotic consumption and the prevalence of VRE. The total consumption of antibiotics increased significantly from 450.6 DDDs/1,000 PDs in 2010 to 520.1 DDDs/1,000 PDs in 2019 (P = 0.013). Positive correlations were found between the prevalence of vancomycin-resistant Enterococcus faecium and the consumption of amoxicillin/clavulanate, vancomycin, and carbapenems, which included meropenem (P < 0.05). The increase in total VRE prevalence was significantly correlated with increased consumption of vancomycin and carbapenems, which included meropenem (P < 0.05). This 10-year study in a hospital demonstrated changes in antimicrobial use, which may have affected VRE prevalence in the hospital. We found a rise in nosocomial VRE prevalence was associated with the use of specific antimicrobial agents.

National Surveillance of Antimicrobial Susceptibility of Bacteremic Gram-Negative Bacteria with Emphasis on Community-Acquired Resistant Isolates: Report from the 2019 Surveillance of Multicenter Antimicrobial Resistance in Taiwan (SMART).

A multicenter collection of bacteremic isolates of Escherichia coli (n = 423), Klebsiella pneumoniae (n = 372), Pseudomonas aeruginosa (n = 300), and Acinetobacter baumannii complex (n = 199) was analyzed for susceptibility. Xpert Carba-R assay and sequencing for mcr genes were performed for carbapenem- or colistin-resistant isolates. Nineteen (67.8%) carbapenem-resistant K. pneumoniae (n = 28) and one (20%) carbapenem-resistant E. coli (n = 5) isolate harbored blaKPC (n = 17), blaOXA-48 (n = 2), and blaVIM (n = 1) genes.

A novel preventive mechanism of gentamicin-induced nephrotoxicity by atorvastatin.

Atorvastatin (ATO) inhibits the synthesis of nonsteroidal isoprenoid compounds and possesses a pleiotropic effect. However, the detailed mechanism of ATO in preventing gentamicin (GM)-induced renal injury remains obscure. Although underlying multifaceted mechanisms involving GM-induced nephrotoxicity were well known, further work on elucidating the essential mechanism was needed. Using a fluorogenic derivatization-liquid chromatography tandem mass spectrometry proteomic method (FD-LC-MS/MS method), we investigated the effects and mechanisms of ATO treatment on GM-induced nephrotoxicity in rats. Consequently, 49 differentially expressed proteins were identified. The most significant mechanisms of nephrotoxicity caused by GM were mitochondrial dysfunction, fatty acid metabolism and oxidative stress. Their upstream regulator was found to be PPARα. The proteins involved in GM nephrotoxicity were sodium-hydrogen exchanger regulatory factor (SLC9A3R1), cathepsin V (CTSV), macrophage migration inhibitory factor (MIF) and RhoGDP dissociation inhibitor alpha (ARHGDIA). After ATO intervention, we observed a reversed enrichment pattern of their expression, especially in CTSV and SLC9A3R1 (P-value<0.05). We predicted that ATO may improve abnormal phospholipid metabolism and phospholipidosis caused by GM and also alleviate cell volume homeostasis and reverse the interference of GM with the transporter. Furthermore, proteomic results also provided clues as to GM-induced nephrotoxicity biomarkers such as CTSV and transthyretin.

Nationwide surveillance of antimicrobial resistance among clinically important Gram-negative bacteria, with an emphasis on carbapenems and colistin: Results from the Surveillance of Multicenter Antimicrobial Resistance in Taiwan (SMART) in 2018.

Multicentre surveillance of antimicrobial susceptibility of clinically important Gram-negative bacteria (GNB) from 16 Taiwanese hospitals was performed. Escherichia coli (n = 398), Klebsiella pneumoniae (n = 346), Pseudomonas aeruginosa (n = 252) and Acinetobacter baumannii complex (ABC) (n = 188) bloodstream isolates, non-typhoidal Salmonella (n = 230) and Shigella flexneri (n = 18) from various sources were collected. Antimicrobial MICs were determined using broth microdilution. Genes encoding K. pneumoniae carbapenemases (KPCs), New Delhi metallo-ß-lactamases (NDMs), Verona integron-encoded metallo-ß-lactamase (VIM), OXA-48-like carbapenemase (OXA-48) as well as mcr-1-5 genes were detected by molecular methods. Rates of carbapenem non-susceptibility were 2.8%, 9.0%, 0.4%, 0%, 10.3% and 48.8% for E. coli, K. pneumoniae, Salmonella, Shigella, P. aeruginosa and ABC, respectively. For carbapenemases, one (0.3%) E. coli harboured blaNDM-1. Fifteen (4.3%), two (0.6%) and two (0.6%) K. pneumoniae contained blaKPC, blaOXA-48 and blaVIM, respectively. Two (0.5%) E. coli and fourteen (4.0%) K. pneumoniae were non-wild-type according to the colistin MIC. Among Enterobacteriaceae with a colistin MIC ≥ 2 mg/L, mcr-1 was detected in one E. coli, two K. pneumoniae and three Salmonella spp. All three mcr-1-positive Salmonella isolates were collected from community-acquired infections; none of the six mcr-1-positive Enterobacteriaceae were carbapenem-resistant. Carbapenem resistance has increased among clinically important GNB, especially among hospital-acquired infections. blaKPC, especially the blaKPC-2 variant, was detected in approximately one-half of the carbapenem-resistant K. pneumoniae isolates in this study. Although resistance rates to colistin remained low among Enterobacteriaceae, the finding of mcr-1 from different species raises concern of potential dissemination.

Predominance of methicillin-resistant Staphylococcus aureus in the residents and environments of long-term care facilities in Taiwan.

BACKGROUND/PURPOSE: This study investigated the distribution and persistence of multidrug resistant organisms (MDROs) including methicillin-resistant Staphylococcus aureus (MRSA), carbapenem-resistant Enterobacteriaceae (CRE), carbapenem-resistant Pseudomonas aeruginosa (CRPA), and multidrug-resistant Acinetobacter baumannii (MDRAB) in six long-term care facilities (LTCFs). METHODS: We investigated the distribution of MDROs in residents of six LTCFs and their environments from January to December 2016 (intervention period). Active surveillance of colonization of MDROs was performed by culturing rectal and nasal swab samples from the residents every three months. Multilocus sequence typing (MLST) was conducted, and genes for panton-valentine leukocidin (PVL) from MRSA isolates were determined. RESULTS: A total of 521 samples were positive for MDROs, and MRSA was the most common organism (65.1%), followed by MDRAB (11.3%), carbapenem-resistant Klebsiella pneumoniae (11.1%), carbapenem-resistant Escherichia coli (4.6%), and carbapenem-resistant P. aeruginosa (2.1%, n = 11). By a linear regression model, positive MRSA isolates from the environment were found to be statistically significant and associated with the number of colonized LTCF residents (p = 0.01), while the timing of the surveillance culture was not (p = 0.227). The main MLST types associated with PVL-production were sequence type (ST) 59, (40.0%, 24/60), ST30 (21.4%, 3/14), ST8 (87.5%, 14/16), and ST45 (3.6%, 1/28). The susceptibility rates of tetracycline (96.7%), trimethoprim-sulfamethoxazole (96.7%), and ciprofloxacin (81.7%) were statistically significant and higher in MRSA ST59, compared to the rates in MRSA ST45 isolates. CONCLUSIONS: MRSA was the most commonly colonized MDRO, both in the LTCF residents and in the environment, followed by MDRAB and carbapenem-resistant K. pneumoniae.

National bundle care program implementation to reduce ventilator-associated pneumonia in intensive care units in Taiwan.

BACKGROUND/PURPOSE: This study investigated the impact of implementing ventilator-associated pneumonia (VAP) bundle care on the rates of VAP in intensive care units (ICUs) in Taiwan. METHODS: A total of 10 ICUs (bed number, 170), including surgical (SICUs) (n = 7), cardiovascular/surgical (CV/S-ICUs) (n = 1), and medical ICUs (MICUs) (n = 2) from 10 hospitals (7 medical center hospitals and 3 regional hospitals) were enrolled in this quality-improvement project. This study was divided into the pre-intervention phase (1st January, 2012-31st July, 2013) and the intervention phase (1st August, 2013-31st October, 2014). RESULTS: Among the 10 hospitals, the overall rates (cases per 1000 ventilator-days) of VAP declined significantly (p = 0.005; rate ratio, 0.71) from 1.9 in the pre-intervention period to 1.5 in the intervention period. Significant difference in VAP rates between these periods was found in the regional hospitals (from 1.6 to 0.7; p < 0.001) and the SICUs (from 2.1 to 1.4; p < 0.001), but not in the medical centers (2.0 vs. 1.9; p = 0.0667) or CV/S-ICUs (4.5 vs. 4.5; p = 0.5391). However, VAP rate increased significantly (cases per 1000 ventilator-days) in the MICUs between the two periods (from 0.5 to 1.0; p = 0.0489). For the VAP bundle care elements, the overall compliance rate was 87.7% with 83.6% and 97.9% in the medical centers and regional hospitals, respectively. CONCLUSIONS: Implementing VAP bundle care has effectively reduced VAP in Taiwanese ICUs, but differences in performance and compliance rates of VAP bundle care among the different ICUs and hospital categories did exist.

Splenic Abscess: An Uncommon Entity with Potentially Life-Threatening Evolution.

BACKGROUND/PURPOSE: Splenic abscess is rare with potentially life-threatening evolution. The aim of this study is to review the clinical features, microbiological etiologies, treatment, and outcomes of patients with splenic abscess. METHODS: We reviewed the admitted patients with suspected splenic abscess and made the diagnosis of splenic abscess. The clinical characteristics, underlying diseases, treatment course, organism spectra, abscess number and size, therapeutic methods, and clinical outcome at a tertiary medical center in Taiwan over a period of 5 years were analyzed. RESULTS: Of 16 patients with splenic abscess, the male to female ratio was 1 : 1. Common presentations were fever (11 patients, 68.7%), diffuse abdominal pain (6 patients, 37.5%), left upper quadrant pain or tenderness (6 patients, 37.5%), and left-sided pleural effusions (8 patients, 50%). Antimicrobial therapy was administered in all patients. Fourteen (87.5%) patients recovered under medical treatment. One (6.2%) patient underwent splenectomy, four (25%) patients performed percutaneous drainage of their splenic abscess, and 11 (68.7%) patients received antimicrobial therapy alone. CONCLUSION: We noted that mortality may be more related to patients with underlying immunodeficiency. Patients with splenic abscesses receiving antimicrobial therapy alone were in a relatively high proportion and got a good prognosis especially in patients with small and multiple abscesses.

Implementation of a national bundle care program to reduce central line-associated bloodstream infections in intensive care units in Taiwan.

BACKGROUND/PURPOSE: This study assessed the effect of the central line bundle on the rate of central line-associated bloodstream infections (CLABSI) in intensive care units (ICUs) in Taiwan. METHODS: This national study was conducted in 27 ICUs with 404 beds total, including 15 medical ICUs, 11 surgical ICUs, and one mixed ICU. The study period was divided into two phases: a pre-intervention (between June 1, 2011 and October 31, 2011) and intervention phase (between December 1, 2011 and October 31, 2012). Outcome variables, including CLABSI rates (per 1000 catheter-days) and catheter utilization rates, were measured. RESULTS: The overall rate of CLABSI significantly decreased by 12.2% (p < 0.001) from 5.74 per 1000 catheter-days in the pre-intervention phase to 5.04 per 1000 catheter-days in the intervention phase. The catheter utilization rate decreased by 1.1% from 55.3% in the pre-intervention phase to 54.2% in the intervention phase. The decline in CLABSI varied significantly among hospital and ICU levels, except surgical ICUs (p = 0.59). CONCLUSIONS: Implementing a multidimensional central-line bundle significantly reduced the rates of CLABSI by 12.2% in nearly all participating ICUs, except surgical ICUs.
