Point Prevalence Survey of Antimicrobial Utilization in Ghana’s Premier Hospital: Implications for Antimicrobial Stewardship

The first comprehensive point prevalence survey at the Korle Bu Teaching Hospital (KBTH) was performed as part of the 2019 Global Point Prevalence Survey (Global-PPS) on antimicrobials. The aim was to establish a PPS baseline for the whole hospital and to identify required stewardship interventions. The PPS was conducted over three days in June 2019 using the GLOBAL-PPS standardized method for surveillance of antimicrobial utilization in hospitals to evaluate antimicrobial prescribing. In all, 988 patients were admitted to 69 wards. Overall antimicrobial prevalence was 53.3%. More community-acquired infections (CAI) were treated empirically compared to health-care associated infections (94.0% vs. 86.1% respectively, p = 0.002). Main indications for prescribing antimicrobials were pneumonia (18.4%), skin and soft tissue infections (11.4%) and sepsis (11.1%). Among antimicrobials, systemic antibiotics accounted for 83.5%, of which amoxicillin with beta-lactam inhibitor (17.5%), metronidazole (11.8%) and ceftriaxone (11.5%) dominated. Guideline compliance was 89.0%. Stop/review dates were completed in 33.4% and documented reason was recorded in 53.0% of all prescriptions. If the findings in this PPS can be addressed antimicrobial stewardship at the KBTH stands to improve significantly.

Incidence of healthcare-associated infections with invasive devices and surgical procedures in Nepal

SETTING: Dhulikhel Hospital, Kathmandu University Hospital, Kathmandu, Nepal.OBJECTIVES: 1) To report the incidence of health-care-associated infections (HAIs), 2) to compare demographic, clinical characteristics and hospital outcomes in those with and without HAIs; and 3) to verify bacterial types in HAI and community-acquired infections (CAIs) among inpatients with invasive devices and/or surgical procedures.DESIGN: This was a cohort study using secondary data (December 2017 to April 2018).RESULTS: Of 1,310 inpatients, 908 (69.3%) had surgical procedures, 125 (9.5%) had invasive devices and 277 (21.1%) both. Sixty-six developed HAIs (incidence = 5/100 patient admissions, 95% CI 3.9–6.3). Individuals with HAIs had a 5.5-fold higher risk of longer hospital stays (7 days) and a 6.9-fold risk of being in intensive care compared to the surgical ward. Unfavourable hospital exit outcomes were higher in those with HAIs (4.5%) than in those without (0.9%, P = 0.02). The most common HAI bacteria (n = 70) were Escherichia coli (44.3%), Enterococcus spp. (22.9%) and Klebsiella spp. (11.4%). Of 98 CAIs with 41 isolates, E. coli (36.6%), Staphylococcus aureus (22.0%) and methicillin-resistant S. aureus (14.6%) were common.CONCLUSION: We found relatively low incidence of HAIs, which reflects good infection prevention and control standards. This study serves as a baseline for future monitoring and action.

Complete Genome Sequence of a Polish Enterococcus faecalis vanA -Positive Hospital Isolate

Enterococcus faecalis is an important human pathogen involved in health care-associated infections, and its increasing resistance to vancomycin is worrisome. Here, we report the complete genome sequence of a Polish hospital vanA- positive isolate of E. faecalis , consisting of a 3,264,821-bp chromosome and six plasmids.

Chlorhexidine Gluconate Bathing Program to Reduce Health Care–Associated Infections in Both Critically Ill and Non–Critically Ill Patients

Background Critical care nurses take care of patients with complicated, comorbid, and compromised conditions. These patients are at risk for health care–associated infections, which affect patients’ lives and health care systems in various ways. Objective To gauge the impact of routinely bathing patients with 4% chlorhexidine gluconate solution on the incidence of health care–associated infections in a medical-surgical intensive care unit and a postoperative telemetry unit; to outline the framework for a hospital-wide presurgical chlorhexidine gluconate bathing program and share the results. Methods A standard bathing protocol using a 4% chlorhexidine gluconate solution was developed. The protocol included time studies, training, monitoring, and surveillance of health care–associated infections. Results Consistent patient bathing with 4% chlorhexidine gluconate was associated with a 52% reduction in health care–associated infections in a medical-surgical intensive care unit. The same program in a postoperative telemetry unit yielded a 45% reduction in health care–associated infections. Conclusion A comprehensive daily 4% chlorhexidine gluconate bathing program can be implemented with standardized protocols and detailed instructions and can significantly reduce the incidence of health care–associated infections in intensive care unit and non–intensive care unit hospital settings.

Antimicrobial Resistance and Type III Secretion System Virulotypes of Pseudomonas aeruginosa Isolates from Dogs and Cats in Primary Veterinary Hospitals in Japan: Identification of the International High-Risk Clone Sequence Type 235

Pseudomonas aeruginosa is an environmentally ubiquitous and important opportunistic human pathogen responsible for life-threatening health care-associated infections. Because of its extensive repertoire of virulence determinants and intrinsic and acquired resistance mechanisms, the organism could be one of the most clinically and epidemiologically important causes of morbidity and mortality.

Trained Immunity as a Preventive Measure for Surgical Site Infections

Even with strict implementation of preventive measures, surgical site infections (SSIs) remain among the most prevalent health care-associated infections. New strategies to prevent SSIs would thus have a huge impact, also in light of increasing global rates of antimicrobial drug resistance. Considering the indispensable role of innate immune cells in host defense in surgical wounds, enhancing their function may represent a potential strategy for prevention of SSIs.
