Health-care-associated infections (HAIs) are considered a serious public health issues that contribute substantially to the global burden of mortality and morbidity with respect to infectious diseases. The aim is to assess the burden of health-care-associated infections by collation of available data from published point prevalence surveys (PPS) on HAIs to give future guidance. Study protocol and methodology were designed according to preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines. Published research papers that conducted a point prevalence survey of HAIs in hospital settings by following the structured survey methodology employed by European Centre of Disease Prevention and Control (ECDC) were included. Of 1212 articles, 67 studies were included in the final analysis conducted across different countries. Overall, 35 studies were conducted in Europe, 21 in Asia, 9 in America, and 2 in Africa. The highest prevalence of HAIs was recorded in a study conducted in adult ICU settings of 75 regions of Europe (51.3%). The majority of the studies included HAI data on urinary tract infections, respiratory tract infections, and bloodstream infections. Klebsiella pneumonia, Pseudomonas aeruginosa and E. coli were the most frequent pathogens responsible for HAIs. PPS is an useful tool to quantify HAIs and provides a robust baseline data for policymakers. However, a standardize surveillance method is required. In order to minimize the burden of HAIs, infection prevention and control programs and antibiotic stewardship may be effective strategies to minimize the risk of HAIs.

Point prevalence surveys of health-care-associated infections: a systematic review

Background We conducted a national point prevalence survey (PPS) to determine the prevalence of healthcare-associated infections (HAIs) and antimicrobial use (AMU) in Singapore acute-care hospitals. Methods Trained personnel collected HAI, AMU, and baseline hospital- and patient-level data of adult inpatients from 13 private and public acute-care hospitals between July 2015 and February 2016, using the PPS methodology developed by the European Centre for Disease Prevention and Control. Factors independently associated with HAIs were determined using multivariable regression. Results Of the 5415 patients surveyed, there were 646 patients (11.9%; 95% confidence interval [CI], 11.1%-12.8%) with 727 distinct HAIs, of which 331 (45.5%) were culture positive. The most common HAIs were unspecified clinical sepsis (25.5%) and pneumonia (24.8%). Staphylococcus aureus (12.9%) and Pseudomonas aeruginosa (11.5%) were the most common pathogens implicated in HAIs. Carbapenem nonsusceptibility rates were highest in Acinetobacter species (71.9%) and P. aeruginosa (23.6%). Male sex, increasing age, surgery during current hospitalization, and presence of central venous or urinary catheters were independently associated with HAIs. A total of 2762 (51.0%; 95% CI, 49.7%-52.3%) patients were on 3611 systemic antimicrobial agents; 462 (12.8%) were prescribed for surgical prophylaxis and 2997 (83.0%) were prescribed for treatment. Amoxicillin/clavulanate was the most frequently prescribed (24.6%) antimicrobial agent. Conclusions This survey suggested a high prevalence of HAIs and AMU in Singapore's acute-care hospitals. While further research is necessary to understand the causes and costs of HAIs and AMU in Singapore, repeated PPSs over the next decade will be useful to gauge progress at controlling HAIs and AMU.

Prevalence of Healthcare-Associated Infections and Antimicrobial Use Among Adult Inpatients in Singapore Acute-Care Hospitals: Results From the First National Point Prevalence Survey

Australia does not have a national healthcare associated infection (HAI) surveillance program. Only one HAI point prevalence study has been undertaken in 1984. The objective of this study was to estimate the burden of healthcare associated infection (HAI) in acute adult inpatients in Australia. A cross sectional point prevalence study (PPS) was conducted in a sample of large acute care hospitals. All data were collected by two trained Research Assistants. Surveillance methodology was based on the European Centre for Disease Prevention and Control (ECDC) PPS Protocol with variation in the sampling method in that only acute inpatients ≥ 18 years old were included. ECDC HAI definitions were applied. Data was collected between August and November 2018. A total of 2767 patients from 19 hospitals were included in the study. The median age of patients was 67, and 52.9% of the sample were male. Presence of a multi-drug resistant organism was documented for 10.3% of the patients. There were 363 HAIs present in 273 patients. The prevalence of patients with a HAI was 9.9% (95%CI: 8.8–11.0). Hospital prevalence rates ranged from 5.7% (95%CI:2.9–11.0) to 17.0% (95%CI:10.7–26.1). The most common HAIs were surgical site infection, pneumonia and urinary tract infection, comprising 64% of all HAIs identified. This is the first HAI PPS to be conducted in Australia in 34 years. The prevalence rate is higher than the previous Australian study and that reported by the ECDC, however differences in methodology limit comparison. Regular, large scale HAI PPS should be undertaken to generate national HAI data to inform and drive national interventions.

The prevalence of healthcare associated infections among adult inpatients at nineteen large Australian acute-care public hospitals: a point prevalence survey

Introduction: In view of increasing concerns with antimicrobial resistance (AMR), the World Health Organization (WHO) instituted a Global Action Plan (GAP) to address this. Area covered: One of the strategies to achieve the goals of GAP is to conduct regular surveillance of antimicrobial use through point prevalence surveys (PPS). In this review, PubMed, EBSCO, Proquest, Cinahl, and Scopus were searched for PPS of antimicrobial use published in English between January 2000 and December 2019. After systematic database screening of 2,893 articles, 60 PPS met the inclusion criteria and consequently were incorporated in this systematic review. Expert opinion: This review highlighted that most of the PPS were conducted in upper-middle and high-income countries. Prevalence of antimicrobial use was significantly higher in non-European hospitals compared with European hospitals. The domination of third-generation cephalosporin and fluoroquinolones use across all the regions suggests substantial use of broad-spectrum antimicrobials across countries. Among all identified regions around the world, India was the region where the highest use of antimicrobials was observed. Although PPS is a useful tool to assess the pattern of antimicrobial use and provides a robust baseline; however, a standardized surveillance method is needed. In order to optimize antimicrobial use, more efforts are required to improve antimicrobial use.

Point prevalence surveys of antimicrobial use: a systematic review and the implications

BACKGROUND Infections in critically ill patients are the main reasons for a lack of therapeutic success and increased mortality in intensive care units (ICUs). There have been many analyses of the incidence of infections in ICUs; however, no large studies of this kind have been conducted either in Poland or in Eastern and Central Europe. OBJECTIVES The aim of the research was to undertake a one-day study of the prevalence of infections in ICUs in Warszawa and the Mazovian region of Poland. MATERIAL AND METHODS A prospective questionnaire survey analysis - a one-day prevalence study of infections - was carried out on June 25, 2014, in 28 ICUs in Poland. RESULTS Among 205 ICU patients (193 adults and 12 children), 134 infections were found in 101 patients (99/193 adults (51.30%) and 2/12 children (16.70%)), and bacterial colonization in 19/205 (9.3%) patients. In 66.42% of the cases, more than 1 site of infection was diagnosed. On the day of the study, 75.40% of the diagnosed infections had positive microbiological results. The most frequent were respiratory tract infections (53.73%), wound infections (18.65%) and bloodstream infections (14.92%). Most of the infections (64.10%) were caused by Gram-negative bacteria (GN), followed by Gram-positive bacteria (GP; 31.80%) and fungi (4.10%). The most frequently reported GN microorganisms were Enterobacteriaceae (44.7%). Methicillin-resistant Staphylococcus aureus (MRSA) infections were found in 8.80% of the patients. Antibiotics were administered to 75.60% of the adult patients, in 69.20% as targeted treatment. Mechanical ventilation, central vein catheterization and urinary bladder catheterization were used in 67.80%, 85.85% and 94.63% of the patients, respectively. CONCLUSIONS On the day of the study, more than half of the patients had infections, mostly from GN bacteria. Respiratory tract infections were the main type found. In about 2/3 of the patients, antibiotics were administered, mainly as targeted therapy.
