Prevalence of antimicrobial use and active healthcare-associated infections in acute care hospitals: a multicentre prevalence survey in Japan.

ABSTRACT: OBJECTIVE:To determine the prevalence of antimicrobial drug use and active healthcare-associated infections (HAIs) and to evaluate the appropriateness of antimicrobial therapy in acute care hospitals in Japan. DESIGN:A prospective multicentre cross-sectional study. PARTICIPANTS:All hospitalised patients on a survey day. MAIN OUTCOME MEASURES:The primary outcome was the proportion of patients receiving any antimicrobial agents. The secondary outcome was the proportion of patients with active HAIs. The reasons for antimicrobial drug use and appropriateness of antibiotic therapy were also investigated. RESULTS:Eight hundred twenty eligible patients were identified. The median patient age was 70?years (IQR 55-80); 380 (46.3%) were women, 150 (18.3%) had diabetes mellitus and 107 (13.1%) were immunosuppressive medication users. The proportion of patients receiving any antimicrobial drugs was 33.5% (95% CI 30.3% to 36.8%). The proportion of patients with active HAIs was 7.4% (95% CI 5.6% to 9.2%). A total of 327 antimicrobial drugs were used at the time of the survey. Of those, 163 (49.8%), 101 (30.9%) and 46 (14.1%) were used for infection treatment, surgical prophylaxis and medical prophylaxis, respectively. The most commonly used antimicrobial drugs for treatment were ceftriaxone (n=25, 15.3%), followed by piperacillin-tazobactam (n=22, 13.5%) and cefmetazole (n=13, 8.0%). In the 163 antimicrobial drugs used for infection treatment, 62 (38.0%) were judged to be inappropriately used. CONCLUSIONS:The prevalence of antimicrobial use and active HAIs and the appropriateness of antimicrobial therapy in Japan were similar to those of other developed countries. A strategy to improve the appropriateness of antimicrobial therapy provided to hospitalised patients is needed. TRIAL REGISTRATION NUMBER:UMIN000033568.

Project description:BackgroundThe burden of healthcare-associated infections (HAIs) and the extent of antimicrobial use (AU) are periodically recorded through Point Prevalence Surveys (PPS) in acute care hospitals coordinated by the European Centre for Disease Prevention and Control (ECDC). In previous PPSs, Greece demonstrated increased HAI and AU prevalence: 9% and 54.7% in 2011-2012, and 10% and 55.6% in 2016-2017, respectively. The 2022 PPS aimed to estimate HAIs and AU indicators among inpatients, especially amid the COVID-19 pandemic.MethodsA cross-sectional study was conducted in 50 hospitals during October-December 2022, in Greece. Patients admitted before 8.00 a.m. of the survey day were observed. Patients with at least one HAI or receiving at least one antimicrobial agent were included. Data were collected by hospital infection control teams. Hospital and ward-level variables were analysed.ResultsFrom 9,707 inpatients, 1,175 had at least one HAI (12.1%), and 5,376 were receiving at least one antimicrobial (55.4%). Intensive care unit patients had the highest HAI (45.7%) and AU (71.3%) prevalence. Of the 1,408 recorded HAIs, lower respiratory tract (28.9%), bloodstream (20%), and urinary tract infections (13.1%) were the most common. Among 1,259 isolates, Klebsiella (20.5%) and Acinetobacter (12.8%) were most frequently identified. Resistance to first-level antibiotic markers was 69.3%. Among the 9,003 antimicrobials, piperacillin-tazobactam (10.9%), and meropenem (7.7%) were frequently prescribed. The ratio of broad-spectrum to narrow-spectrum antibiotics was 1.4. As defined by the 2021 WHO AWaRe (Access, Watch, Reserve) classification, restricted classes of Watch and Reserve agents comprised 76.7% of antibiotics. Usual indications were treatment of community-acquired infections (34.6%) and HAIs (22.9%). For surgical prophylaxis, cefoxitin was commonly used (20.2%), and typical courses (75.7%) lasted more than one day. HAI and AU prevalence were positively associated with bed occupancy (p = 0.027) and secondary hospitals (p = 0.014), respectively.ConclusionsThe 2022 PPS highlighted the increasing trend of HAI prevalence and high AU prevalence in Greece, the emergence of difficult-to-treat pathogens, and the extensive use of broad-spectrum antimicrobials. Strengthening infection control and antimicrobial stewardship programs in hospital settings is essential.

Project description:BackgroundAntimicrobial resistance (AMR) is a public health crisis of global proportions. Data is required to understand the local drivers of antimicrobial resistance and support decision-making processes including implementation of appropriate antimicrobial stewardship strategies.ObjectivesTo measure antimicrobial usage in hospitals in Ghana.MethodsUsing the Global Point Prevalence instruments and processes, we conducted point prevalence surveys across AMR surveillance sentinel hospitals in Ghana, between September and December 2019. Hospital records of all inpatients on admission at 0800 hours on a specific day were reviewed for antimicrobial use at the time of the survey. Data on antibiotic use, including indication for use and quality of prescribing were recorded.ResultsOverall prevalence of antibiotic use across the sentinel sites was 54.9% (n = 1591/2897), ranging between 48.4% (n = 266/550) and 67.2% (n = 82/122). The highest prevalence of antibiotic use 89.3% (n = 25/28) was observed in adult ICUs. The average number of antibiotics prescribed per patient was 1.7 (n = 1562/2620), with the majority (66%, n = 728/2620) administered via the parenteral route. The five most-commonly used antibiotics were metronidazole (20.6%, n = 541/2620), cefuroxime (12.9%, n = 338/2620), ceftriaxone (11.8%, n = 310/2620), amoxicillin/clavulanic acid (8.8%, n = 231/2620) and ciprofloxacin (7.8%, n = 204/2620). The majority (52.2%; n = 1367/2620) of antibiotics were prescribed to treat an infection, whilst surgical prophylaxis accounted for 26.1% (n = 684/2620).ConclusionsWe observed a high use of antibiotics including metronidazole and cephalosporins at the participating hospitals. Most antibiotics were empirically prescribed, with low use of microbiological cultures. High usage of third-generation cephalosporins especially for community-acquired infections offers an opportunity for antibiotic stewardship interventions.

Project description:BackgroundHealthcare-associated infections (HAIs) and antimicrobial use (AMU) are important drivers of antimicrobial resistance, yet there is minimal data from the Pacific region. We sought to determine the point prevalence of HAIs and AMU at Fiji's largest hospital, the Colonial War Memorial Hospital (CWMH) in Suva. A secondary aim was to evaluate the performance of European Centre for Diseases Prevention and Control (ECDC) HAI criteria in a resource-limited setting.MethodsWe conducted a point prevalence survey of HAIs and AMU at CWMH in October 2019. Survey methodology was adapted from the ECDC protocol. To evaluate the suitability of ECDC HAI criteria in our setting, we augmented the survey to identify patients with a clinician diagnosis of a HAI where diagnostic testing criteria were not met. We also assessed infection prevention and control (IPC) infrastructure on each ward.ResultsWe surveyed 343 patients, with median (interquartile range) age 30 years (16-53), predominantly admitted under obstetrics/gynaecology (94, 27.4%) or paediatrics (83, 24.2%). Thirty patients had one or more HAIs, a point prevalence of 8.7% (95% CI 6.0% to 12.3%). The most common HAIs were surgical site infections (n = 13), skin and soft tissue infections (7) and neonatal clinical sepsis (6). Two additional patients were identified with physician-diagnosed HAIs that failed to meet ECDC criteria due to insufficient investigations. 206 (60.1%) patients were receiving at least one antimicrobial. Of the 325 antimicrobial prescriptions, the most common agents were ampicillin (58/325, 17.8%), cloxacillin (55/325, 16.9%) and metronidazole (53/325, 16.3%). Use of broad-spectrum agents such as piperacillin/tazobactam (n = 6) and meropenem (1) was low. The majority of prescriptions for surgical prophylaxis were for more than 1 day (45/76, 59.2%). Although the number of handwashing basins throughout the hospital exceeded World Health Organization recommendations, availability of alcohol-based handrub was limited and most concentrated within high-risk wards.ConclusionsThe prevalence of HAIs in Fiji was similar to neighbouring high-income countries, but may have been reduced by the high proportion of paediatric and obstetrics patients, or by lower rates of inpatient investigations. AMU was very high, with duration of surgical prophylaxis an important target for future antimicrobial stewardship initiatives.

Project description:ObjectiveTo delineate the prevalence and factors associated with antimicrobial use across six referral hospitals in Tanzania using WHO point prevalence survey (PPS) methodology to inform hospital-specific antimicrobial stewardship programmes.DesignCross-sectional analytical study.SettingSix referral hospitals in Tanzania.ParticipantsPatients irrespective of age and gender (n=948) admitted in the six referral hospital wards before 8:00 hours on each day of the survey were included in December 2019. Using the WHO PPS methodology, data on hospitals, wards, patients, antibiotics, and indications for antibiotics were collected.Outcome measuresWe analysed the prevalence of antibiotic use by referral hospital, ward, indication and patient characteristics as the main outcomes. We also described adherence to the Tanzania Standard Treatment Guidelines (STG) and WHO's AWaRe categorisation of antibiotics.ResultsApproximately 62.3% of inpatients were prescribed antibiotics, predominantly from the Access group of antibiotics (ceftriaxone, metronidazole or ampicillin-cloxacillin). The overall adherence of antibiotic prescriptions to the Tanzania STG was high (84.0%), with the exception of Sekou Toure Regional Referral Hospital (68.0%) and Maweni Regional Referral Hospital (57.8%). The most common indication for antibiotic prescriptions was community-acquired infections (39.8%). Children less than 2 years of age (OR 1.73, 95% CI 1.02 to 2.92, p=0.039); admission to surgical wards (OR 4.90, 95% CI 2.87 to 8.36, p <0.001); and admission to paediatric wards (OR 3.93, 95% CI 2.16 to 7.15, p <0.001) were associated with increased odds of antibiotic use. Only 2 of 591 patients were prescribed antibiotics based on culture and antimicrobial susceptibility testing results.ConclusionsEmpirical use of antibiotics is common, and the Access group of antibiotics is predominantly prescribed in children less than 2 years and patients admitted to surgical and paediatric wards. Lack of utilisation of antimicrobial susceptibility testing services in these hospitals requires urgent interventions. Routine monitoring of antibiotic use is recommended to be part of antibiotic stewardship programmes in Tanzania.
