Level of implementation of multimodal strategies for infection prevention and control interventions and prevalence of healthcare-associated infections in Northern Italy

BACKGROUND

In November 2022, Italy participated in the third edition of the European Centre for disease prevention and control (ECDC) point prevalence survey (PPS) of healthcare-associated infections (HAIs) in acute-care hospitals. A questionnaire based on the WHO infection prevention and control assessment framework (IPCAF) was included, which aims to investigate multimodal strategies for the implementation of IPC interventions.

METHODS

A PPS was conducted using the ECDC PPS protocol version 6.0. The Regional health authority of the region of Piedmont, in north-western Italy, chose to enlist all public acute-care hospitals. Data were collected within one day per each ward, within 3 weeks in each hospital, at hospital, ward and patient level. A score between 0-1 or 0-2 was assigned to each of the 9 items in the IPCAF questionnaire, with 14 points representing the best possible score. HAI prevalence was calculated at the hospital-level as the percentage of patients with at least one HAI over all included patients. Relations between HAI prevalence, IPCAF score, and other hospital-level variables were assessed using Spearman's Rho coefficient.

RESULTS

In total, 42 acute-care hospitals of the region of Piedmont were involved, with a total of 6865 included patients. All participant hospitals reported they employed multimodal strategies to implement IPC interventions. The median IPCAF overall score was 11/14 (interquartile range, IQR: 9.25-12). The multimodal strategy with the highest level of adherence was education and training, followed by communication and reminders. Strategies with the lowest level of adherence were safety climate and culture of change, and system change. Overall HAI prevalence was 8.06%. A weak to moderate inverse relation was found between IPCAF score and HAI prevalence (Spearman's Rho -0.340, p 0.034). No other significant correlation was found.

CONCLUSIONS

This study found a high self-reported overall level of implementation of multimodal strategies for IPC in the region. Results of this study suggest the relevance of the multimodal approach and the validity of the IPCAF score in measuring IPC programs, in terms of effectiveness of preventing HAI transmission.

Prevalence of antimicrobial use and healthcare-associated infections in the UAE: Results from the first nationwide point-prevalence survey

OBJECTIVES

The WHO's Global Antimicrobial Resistance Surveillance System (GLASS) 2017-2018 reported a significant increase in antimicrobial resistance among nosocomial pathogens. This was the first national point of prevalence survey in United Arab Emirates.

METHODS

A one-day multicenter cross-sectional survey using a unified web-based platform was conducted in forty-four hospitals across the country from 3 to 23 November 2019 to estimate the prevalence of antimicrobial use and healthcare-associated infections among both governmental and private sectors.

RESULTS

All in all, 3657 inpatients in the 44 participating hospitals were surveyed; 51.4 % were on at least one antibiotic at that time. Pneumonia was the most frequently reported hospital-acquired (47 %), followed by intra-abdominal sepsis (10.9 %), upper respiratory tract infections (10.6 %), and urinary tract infections (9.9 %). Ceftriaxone and piperacillin/Tazobactam were the most frequently used antibiotics (13.5 %, 9.6 %). Compliance with guidelines was reported in 70.3 % of prescriptions. Only 11.4 % of patients received a single dose of surgical prophylaxis.

CONCLUSION

Our results on antimicrobial use and hospital-acquired infection prevalence are comparable to other regional and international findings. Local guidelines are needed to reduce the excessive use of Watch and Reserve antibiotics, reduce prolonged antibiotic use after surgery, and decrease hospital-acquired infections.

Global-PPS targets for antimicrobial stewardship in paediatric patients at hospitals in Sanandaj, Western Iran, compared with Southeast Asian and European hospitals

OBJECTIVES

Point prevalence surveys (PPS) provide valuable data on patterns of hospital antimicrobial administration. To identify quality improvement indicators, we evaluated antimicrobial prescribing patterns in children and neonates admitted to three referral centres in Sanandaj, Western Iran, and compared these with Southeast Asian and European paediatric benchmark data.

METHODS

The standardised Global-PPS was performed to assess antimicrobial use in Southeast Asia, including Sanandaj and European hospitals, in 2019.

RESULTS

Of the 4118, 2915, and 443 paediatric patients enrolled in Southeast Asian, European and Sanandaj hospitals, 2342 (56.9%), 833 (28.6%) and 332 (74.9%), respectively, received at least one antimicrobial in 2019. The most administered antibiotics in neonates were ampicillin in Southeast Asia (30.3%) and Sanandaj (41.5%, often in combination with cefotaxime (29.0%)), compared with amoxicillin in Europe (20.0%). In children, ceftriaxone was most prescribed in Sanandaj (62.4%) and Southeast Asia (20.5%) as opposed to amoxicillin (11.8%) in Europe. Twice as many Watch antibiotics (83.0%) were prescribed on paediatric wards in Sanandaj compared with European paediatric wards (41.1%). All antimicrobials in Sanandaj hospitals were prescribed empirically, and prolonged surgical prophylaxis was common (75.5%).

CONCLUSION

The high prevalence of antibiotic prescribing, high empirical therapies, and poor outcomes for antibiotic quality indicators strongly suggest the urgent need for an antibiotic stewardship program in Sanandaj hospitals, where improved diagnostic laboratory capacity and reconsideration of training may be good targets for intervention in their hospitals.

Healthcare-associated infections and antimicrobial use in acute care hospitals in Greece, 2022; results of the third point prevalence survey

BACKGROUND

The 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.

METHODS

A 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.

RESULTS

From 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.

CONCLUSIONS

The 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.

Antibiotic point prevalence survey and antimicrobial resistance in hospitalized patients across Peruvian reference hospitals

BACKGROUND

Peru reports higher levels than other countries in Latin America of resistance to antimicrobials among Gram-positive and Gram-negative bacteria, however data on antibiotic use in Peru are scarce. This study aims to estimate the prevalence and quality of antibiotic prescription in hospitalized patients and to determine the antibiotic susceptibility rates of bacteria causing key bacterial infections.

METHODS

We carried out a point prevalence survey of antibiotic prescription at ten public hospitals in nine regions of Peru. Data was collected from patients hospitalized during a 3-week period, with details about antibiotic use, patient information, and antimicrobial susceptibility.

RESULTS

1620 patient charts were reviewed; in 924 cases antibiotics were prescribed (57.0 %, range 45.9-78.9 %). Most of the antibiotics (74.2 %) were prescribed as empirical treatment, only 4.4 % as targeted treatment. For 9.5 % of cases the reason for antibiotic use was unknown. Cephalosporins were the most prescribed (30.0 %), followed by carbapenems (11.3 %). Ninety-four blood cultures were positive for bacterial growth, 48.8 % of the Staphylococcus aureus were methicillin-resistant, among Escherichia coli and Klebsiella pneumoniae, 51.7 % and 72.7 % were resistant to third-generation cephalosporins (3GC), 3.4 % and 18.2 % were resistant to carbapenems, respectively. Among bacteria isolated from urine cultures (n = 639), 43.9 % of E. coli and 49.2 % of K. pneumoniae were resistant to 3GC, and 0.9 % of E. coli and 3.2 % of K. pneumoniae were resistant to meropenem.

CONCLUSIONS

The overall proportion of hospitalized patients receiving antibiotics in hospitals from different regions in Peru was high, with only a small proportion receiving targeted treatment. Cephalosporins and carbapenems were the most frequently prescribed antibiotics, reflecting high resistance rates against 3GC and carbapenems in Enterobacterales isolated from blood and urine.

Healthcare infections and antimicrobial consumption in pre-COVID-19 era: a point prevalence survey in three hospitals in a region of Central Italy

Introduction

Healthcare-associated infections (HAIs) are a major global public health concern, increasing the transmission of drug-resistant infections. This point prevalence survey investigated HAIs occurrence and antimicrobial consumption (AMC) in pre-COVID-19 era in the public hospitals of a region of Central Italy.

Methods

Data were collected using the protocol standardised by the European Centre for Disease Prevention and Control.

Results

Three-hundred and sixty-four patients were included (59.3% male) in the study. Overall, HAIs prevalence was 6.6% (95%CI 4.4-9.5), ranging from 5.2% to 7.1% within the surveyed hospitals, with at least one infection in 24 patients (ten each in medical and surgical specialties wards, and four in intensive care). Risk factors for HAIs were advanced age, having undergone surgery and wearing invasive devices. At time of the survey, 44.7% (95%CI 39.7-49.9) of patients was under treatment with at least one antibiotic, and AMC varied between 43% and 48% within hospitals. In all hospitals, a prevalence higher than 10% was found for the prescription reasons other than prophylaxis or therapy.

Conclusions

The results revealed a HAIs prevalence lower than that estimated compared to the most recent national data, in contrast to higher antimicrobial usage. These findings highlight the need to reinforce hygiene practices and develop bundles for HAIs, as a broad implementation of infection prevention and control practices extensively applied to both hub and spoke hospitals could significantly reduce their occurrence, as well as to implement antimicrobial stewardship for prescriptive appropriateness.

A comprehensive point prevalence survey of the quality and quantity of antimicrobial use in Chinese general hospitals and clinical specialties

Antimicrobial resistance (AMR) is a serious, worldwide public health crisis. Surveillance of antimicrobial use forms part of an essential strategy to contain AMR. We aimed to conduct a national point prevalence survey (PPS) on antimicrobial use, and to compare this data with similar international surveillance programs to provide a reference for future AMR strategy development in China. Twenty general hospitals encompassing 10,881 beds and 10,209 inpatients around the country participated the survey using a standardized protocol, at 8am of someday from October 10th to November 31st, 2019. Of the patients, 37.00% (3777/10209) received antimicrobial agents, 31.30% (1630/5208) had surgical operations, and 76.63% (1249/1630) received prophylactic antibiotic. The prevalence of antimicrobial use in medical, surgical, and intensive care units (ICU) patients was 38.84% (1712/4408), 32.07% (1670/5208), and 66.61% (395/593), respectively. Of prescriptions, 5.79% (356/6151) were made in the absence of indication. The intensity of antimicrobial use was 61.25 DDDs/100 patient days, while the intensity of use in internal medicine, surgery, and ICU were 67.79, 45.81, 124.45 DDDs/100 patient days, respectively. Only 11.62% (715/6151) of prescriptions had a reason described in the patient record. Furthermore, 8.44% (210/2487), 14.19% (424/2989), and 12% (81/675) of the prescriptions in internal medicine, surgery, and ICU had a recorded indication, respectively. The review and stop date recorded for antimicrobial therapy was 43.73% (1976/4518). Of the patients, 38.07% (1438/3777) received combination therapy. The classes of antimicrobials prescribed were limited, and the proportion of prescriptions encompassed by the top 20 antimicrobial agents was 75.06% (4617/6151). The prevalence of antimicrobial use in China is close to that of Sweden, the UK, and Canada, but lower than that in India, and higher than that in Switzerland. The data described in this report indicate that the quality of antimicrobial prescriptions requires improvement in China. Further, hospitals should implement professional interventions to improve the rational use of antimicrobials.

Point prevalence survey of antibiotic use and healthcare-associated infections in acute care hospitals: a comprehensive report from the Marche Region of Italy

BACKGROUND

Healthcare-associated infections (HAIs) and antimicrobial resistance (AMR) are serious health challenges. Point prevalence surveys (PPSs) are valuable tools for monitoring HAIs and AMR.

AIM

To describe results of the ECDC PPS 2022 dealing with the prevalence of HAIs, antimicrobial consumption, and associated factors, in acute care hospitals.

METHODS

The survey was performed in November 2022 in 14 hospitals according to the protocol proposed by the European Centre for Disease Prevention and Control. Multilevel logistic regression was performed using geographical area/hospital type as cluster variable to evaluate the factors independently associated with HAIs and antibiotics.

FINDINGS

The point prevalence of HAIs was 7.43%. Patients hospitalized for longer periods were more likely to have an HAI as well as those aged 15-44 years, with a rapidly fatal disease, intubated, and with one or two devices. Antibiotics prevalence was 47.30%. Males, unknown McCabe scores, minimally invasive/non-National Healthcare Safety Network (NHSN) surgery, patients with HAIs, hospitals with a higher alcohol hand-rub consumption, hospitals with a greater number of IPC personnel, geriatric wards, and hospitals with 300-600 beds were more likely to be under antimicrobial therapy.

CONCLUSION

This PPS provided valuable information on the prevalence of HAIs and antimicrobial consumption and variables associated. The high prevalence of HAIs highlights the need for improved infection control measures.

Antibiotic prescribing to inpatients in Limpopo, South Africa: a multicentre point-prevalence survey

BACKGROUND

Electronic continuous surveillance databases are ideal for monitoring antibiotic use (ABU) in hospitalised patients for antibiotic stewardship programmes (ASP). However, such databases are scarce in low-resource settings. Point prevalence surveys (PPS) are viable alternatives. This report describes ABU and identifies ASP implementation improvement areas in Limpopo Province, South Africa.

METHODS

This cross-sectional descriptive study extracted patient-level ABU data from patients' files using a modified global PPS tool. Data were collected between September and November 2021 at five regional hospitals in Limpopo Province, South Africa. All patients in the wards before 8 a.m. on study days with an antibiotic prescription were included. Antibiotic use was stratified by Anatomic Therapeutic Chemical and Access, Watch, Reserve classifications and presented as frequencies and proportions with 95% confidence intervals (CI). Associations between categorical variables were assessed using the chi-square test. Cramér's V was used to assess the strength of these associations.

RESULTS

Of 804 inpatients surveyed, 261 (32.5%) (95% CI 29.2-35.7) were prescribed 416 antibiotics, 137 were female (52.5%) and 198 adults (75.9%). One hundred and twenty-two (46.7%) patients received one antibiotic, 47.5% (124/261) received two, and 5.7% (15/261) received three or more antibiotics. The intensive care units had a higher ABU (68.6%, 35/51) compared to medical (31.3%, 120/384) and surgical (28.5%, 105/369) wards (p = 0.005, Cramér's V = 0.2). Lower respiratory tract infection (27.4%, 104/379), skin and soft tissue infections (SST) (23.5%, 89/379), and obstetrics and gynaecology prophylaxis (14.0%, 53/379) were the common diagnoses for antibiotic prescriptions. The three most prescribed antibiotic classes were imidazoles (21.9%, 91/416), third-generation cephalosporins (20.7%, 86/416) and combination penicillin (18.5%, 79/416). Access antibiotics accounted for 70.2% (292/416) of prescriptions and Watch antibiotics for 29.6% (123/416) (p = 0.110, Cramér's V = 0.1). Reasons for prescribing and treatment plans were documented in 64.9% (270/416) (95% CI 60.3-69.5) and 21.4% (89/416) (95% CI 17.3-25.3) of prescriptions, respectively.

CONCLUSIONS

The study serves as a baseline for ABU surveillance at the five regional hospitals in Limpopo Province. Lack of documentation indicates poor prescribing practices; ASP should address gaps by deploying evidence-based, multifaceted and stepwise interventions.

What is the appropriate antimicrobial use surveillance tool at the health facility level for Uganda and other low- and middle-income countries?

BACKGROUND

An appropriate antimicrobial use (AMU) surveillance system provides critical data and evidence on which antimicrobial stewardship interventions are based. However, Uganda and most other low- and middle-income countries (LMICs) lack efficient systems for monitoring AMU due to unique health system challenges.

METHODS

We reviewed the key tools available for AMU surveillance in health facilities. Based on our implementation experience, we present arguments on the need for country authorities to adapt a customized and standardized tool for national uses.

RESULTS

Despite ongoing efforts to set up AMU surveillance programs in Uganda, AMU data remain sparse, with most of the available data collected through antimicrobial stewardship related continuous quality improvement efforts implemented by global AMR control programs. There is variability in the interpretation of available AMU surveillance tools and a need to identify the most appropriate AMU surveillance methodologies and tools for Uganda and other LMICs. Data fields for sex and gender are incorrectly categorized and there is no tool that records pregnancy variable. Based on the past four years of practical implementation experience since the launch of the World Health Organization's Point Prevalence Survey methodology in 2018 for inpatient settings, we believe that the tool should be modified in cognizance of existing capacity and priorities in resource-constrained settings.

CONCLUSIONS

The World Health Organization, regional experts, ministry of health authorities, and other stakeholders should urgently review available tools with a view to adopting a customized and standardized facility AMU surveillance methodology suitable for national-level rollout in LMICs.

Prevalence of antimicrobial use and healthcare-associated infections in China: Results from the first point prevalence survey in 18 hospitals in Shanxi Province

OBJECTIVES

Inappropriate antimicrobial use (AMU) and healthcare-associated infections (HAIs) are important drivers of antimicrobial resistance, yet data from the developing world are scarce. We conducted the first point prevalence survey (PPS) to determine the prevalence of AMU and HAIs and the suggested targeted interventions for appropriate AMU and HAI prevention in Shanxi Province, China.

METHODS

A multicenter PPS was performed in 18 hospitals in Shanxi. Detailed data on AMU and HAI were collected using the Global-PPS method developed by the University of Antwerp and the methodology developed by the European Centre for Disease Prevention and Control, respectively.

RESULTS

There were 2171 (28.2%) of the 7707 inpatients receiving at least one antimicrobial. The most commonly prescribed antimicrobials were levofloxacin (11.9%), ceftazidime (11.2%) and cefoperazone and beta-lactamase inhibitor (10.3%). Out of the total indications, 89.2% of antibiotics were prescribed for therapeutic, 8.0% for prophylaxis, and 2.8% for either unknown or other. Of the total surgical prophylaxis, 96.0% of antibiotics were given for more than one day. In general, antimicrobials were given mainly parenterally (95.4%) and empirically (83.3%). A total of 264 active HAIs were identified in 239 patients (3.1%), of which 139 (52.3%) were culture positive. The most common HAI was pneumonia (41.3%).

CONCLUSIONS

This survey indicated the relatively low prevalence of AMU and HAIs in Shanxi Province. However, this study has also highlighted several priority areas and targets for quality improvement, and repeated PPSs in the future will be useful to gauge progress at controlling AMU and HAIs.

Antimicrobial use, healthcare-associated infections, and bacterial resistance in general hospitals in China: the first national pilot point prevalence survey report

The purpose of this study is to implement point prevalence survey (PPS), assess antimicrobial prescribing and resistance in general hospitals and clinical specialties in China, and compare them with similar data from other parts of the world. Twenty general hospitals in China were surveyed in October or November, 2019. A standardized surveillance protocol was used to collect data on patient demographics, diagnosis of infection, the prevalence and intensity of antimicrobial use, prescribing quality, bacterium type and resistance spectrum, and the prevalence and type of healthcare-associated infections (HAIs). Overall, 10,881 beds and 10,209 inpatients were investigated. The overall prevalence of antibiotic use was 37.00%, the use of antibiotic prophylaxis in surgical patients was high (74.97%). The intensity of antimicrobial use was 61.25 DDDs/100 patient days. Only 11.62% of antimicrobial prescriptions recorded the reason for prescribing. Intravenous or combination treatments comprised 92.02% and 38.07%, respectively, and only 30.65% of prescriptions referred to a microbiological or biomarker tests. The incidence of HAIs in all patients was 3.79%. The main associated factors for HAIs included more frequent invasive procedures (27.34%), longer hospital stay (> 1-week stay accounting for 51.47%), and low use of alcohol hand rubs (only 29.79% placed it bedside). Most of the resistant bacteria declined; only carbapenem-resistant Enterobacter is higher than previously reported. The prevalence of antibiotic use in general hospitals fell significantly, the overall bacterial resistance declined, and the incidence of HAI was low. However, the low quality of antimicrobial use requires urgent attention.

Identifying and addressing challenges to antimicrobial use surveillance in the human health sector in low- and middle-income countries: experiences and lessons learned from Tanzania and Uganda

BACKGROUND

Antimicrobial resistance (AMR) is a global health security threat and is associated with increased morbidity and mortality. One of the key drivers of AMR is the inappropriate use of antibiotics. A key component of improving antibiotic use is conducting antimicrobial use (AMU) surveillance.

METHODS

USAID Medicines Technologies and Pharmaceutical Services Program has supported the implementation of antimicrobial stewardship activities, including setting up systems for AMU surveillance in Tanzania and Uganda. Results from both countries have been previously published. However, additional implementation experience and lessons learned from addressing challenges to AMU surveillance have not been previously published and are the subject of this narrative article.

RESULTS

The team identified challenges including poor quality data, low digitalization of tools, and inadequate resources including both financial and human resources. To address these gaps, the Program has supported the use of continuous quality improvement approaches addressing gaps in skills, providing tools, and developing guidelines to fill policy gaps in AMU surveillance. Recommendations to fill these gaps, based on the Potter and Brough systematic capacity building model have been proposed.

CONCLUSIONS

Strengthening AMU surveillance through using a capacity-building approach will fill gaps and strengthen efforts for AMR control in both countries.

Prevalence of healthcare-associated infections in public hospitals in New Zealand, 2021

BACKGROUND

There are no contemporary data on healthcare-associated infections (HAIs) in New Zealand.

AIMS

To determine the epidemiology of HAIs, prevalence of medical devices, and microbiology of HAIs in adults in public hospitals in New Zealand.

METHODS

Point prevalence survey. Surveyors reviewed patients aged ≥18 years using the HAI definitions of the European Centres for Disease Prevention and Control. Device use and microbiology of HAIs were recorded.

FINDINGS

In total, 5468 patients were surveyed; 361 patients (6.6%) had 423 HAIs (7.7 HAIs per 100 patients). The most common HAIs were: surgical site infections (N=104, 25%), urinary tract infections (N=80, 19%), pneumonia (N=75, 18%) and bloodstream infections (N=55, 13%). Overall, 3585 patients (66%) had at least one device, with 2922 (53%) patients having a peripheral intravenous catheter. Sixty-nine (16%) HAIs were device-associated. On multi-variable analysis, independent risk factors for HAIs included the presence of a peripheral [odds ratio (OR) 2.0] or central (OR 5.7) intravenous catheter and clinical service. HAI rates were higher in surgical patients (OR 1.8), intensive care unit patients (OR 2.6) and rehabilitation/older persons' health patients (OR 2.4) compared with general medicine patients (P≤0.01 for all groups). In total, 301 organisms were identified. Clostridioides difficile infection was uncommon, accounting for 1.7% of all HAIs. Forty-two isolates (14%) were drug-resistant, and most (N=33, 79%) were Enterobacterales.

CONCLUSION

This study established the most common HAIs and their risk factors in New Zealand. The high prevalence of device use underscores the need to ensure that proven multi-modal prevention interventions are in place. However, as less than half of HAIs are device- or surgery-associated, other intervention strategies will be required to reduce their burden.

Antibiotic point prevalence survey at a tertiary healthcare hospital in India: Identifying strategies to improve the antibiotic stewardship program immediately after a COVID-19 wave

Background

The COVID-19 pandemic has substantially affected the antibiotic stewardship activities in most hospitals of India.

Aims

We conducted an antibiotic point prevalence survey (PPS) immediately after the decline of a major COVID-19 wave at a dedicated COVID-19 hospital. By doing so we aimed to identify the antibiotic prescription patterns, identify factors influencing the choice of antibiotics, and identify/develop strategies to improve the antibiotic stewardship program in such setups.

Methods

The PPS was single-centred, cross-sectional, and retrospective in nature. Patients admitted in various wards and intensive care units (ICUs) between September 2021 to October 2021 were included in our PPS.

Results

Of the included 460 patients, 192 were prescribed antibiotics. Of these 192 patients, ICU-admitted patients had the highest number of antibiotics prescribed i.e. 2.09 ± 0.92. Only a minor fraction (7.92 %) of antibiotics prescriptions were on the basis of culture reports. Most of the antibiotics were prescribed empirically by the parenteral route. The most common group of antibiotics prescribed were third-generation cephalosporins. Carbapenems were the most common designated antibiotics prescribed. A large number of patients (22.40 %) were prescribed a double anaerobic coverage.

Conclusion

The strategies that we identified to improve the antibiotic stewardship program at our institute included reviving the culture of sending culture reports to prescribe antibiotics, improving surgical prophylaxis guidelines, training resident doctors to categorize antibiotic prescriptions appropriately, closely monitoring prescriptions providing double anaerobic coverage, and improving the electronic medical record system for improving prescription auditing.

Evaluation of trends in hospital antimicrobial use in the Lao PDR using repeated point-prevalence surveys-evidence to improve treatment guideline use

BACKGROUND

Antimicrobial use (AMU) is a key driver of antimicrobial resistance (AMR). There are few data on AMU, to inform optimizing antibiotic stewardship, in the Lao PDR (Laos).

METHODS

Point prevalence surveys (PPS) of AMU were conducted at four-month intervals in six general hospitals across Laos from 2017 to 2020, using modified Global-PPS data collection tools. The surveys focused on AMU amongst hospitalized inpatients.

FINDINGS

The overall prevalence of inpatient AMU was 71% (4,377/6,188), varying by hospital and survey round from 50·4% (135/268) to 88·4% (61/69). Of 4,377 patients, 44% received >one antimicrobial. The total number of prescriptions assessed was 6,555. Ceftriaxone was the most commonly used (39·6%) antimicrobial, followed by metronidazole (17%) and gentamicin (10%). Pneumonia was the most common diagnosis among those prescribed antimicrobials in both children aged ≤5 years (29% among aged ≤1 year and 27% among aged >1 to ≤5years) and adults aged ≥15 years at 9%. The percentage of antimicrobial use compliant with local treatment guidelines was 26%; inappropriate use was mainly found for surgical prophylaxis (99%). Adult patients received ACCESS group antimicrobials less commonly than children (47% vs 63%, p-value<0·0001). Most WATCH group prescriptions (99%) were without a microbiological indication.

INTERPRETATION

AMU among hospitalized patients in Laos is high with frequent inappropriate use of antimicrobials, especially as surgical prophylaxis. Continued monitoring and enhanced antimicrobial stewardship interventions are needed in Lao hospitals.

Antimicrobial therapy, resistance, and appropriateness in healthcare-associated and community-associated infections; a point prevalence survey

BACKGROUND

Data examining differences in antimicrobial therapy and its appropriateness between healthcare-associated infections (HAIs) and community-associated infections (CAIs) are limited. The objective was to compare antimicrobial therapy, resistance, and appropriateness between CAIs and HAIs.

METHODS

One-day point prevalence survey targeting admitted patients with active infections was conducted in six tertiary care hospitals. Antimicrobial appropriateness was decided based on hospital antimicrobial guidelines, clinical assessment, culture results, and other relevant investigations.

RESULTS

Out of 1666 patient records reviewed, 240 (14.4%) infection events were identified. Prevalence of infections treated with antimicrobials were 6.5% for HAIs and 7.1% for CAIs. The most commonly prescribed antimicrobials were carbapenems (19.6%), cephalosporins (14.8%), and vancomycin (13.2%), with some differences between HAIs and CAIs. The overall contribution of MDR pathogens to both HAIs and CAIs was similar (34.0% versus 34.3%, p = 0.969). ESBL was significantly associated with CAIs while other gram-negative MDR pathogens significantly associated with HAIs. Overall appropriateness of antimicrobial therapy was similar in HAI and CAI events (64.2% versus 64.7%, p = 0.934). However, it was highest in aminoglycosides (78.6%) and lowest in vancomycin (40.8%). It was lowest in bloodstream infections than other infections (48.5% versus 61% to 78%, p = 0.044).

CONCLUSION

Although the overall burden of MDR pathogens and appropriateness of antimicrobial therapy were similar in HAI and CAI events, there were some differences related to the type of MDR, type of antimicrobials, and type of infection. The current finding can guide training and educational activities of local antimicrobial stewardship initiatives aiming to improve antimicrobial therapy in hospital setting.

Point prevalence survey is useful for introducing effective surveillance of healthcare-associated infections

Background

In Finland, the surveillance of healthcare-associated infections (HAI) became obligatory by the renewed Communicable Diseases Act on the 1^st March 2017.

Aim

To introduce HAI surveillance protocol (HALT-2 by ECDC) in primary care hospitals in the largest hospital district in Finland, and to measure the burden of HAIs and antimicrobial use patterns for improvement.

Methods

Two identical point prevalence surveys (PPS) were organized in autumn 2015 and in spring 2017. The infection control persons (ICP) in the hospitals were inducted to the HAI definitions and the study protocol to collect the data with questionnaires on the study days. The data were checked and analyzed by the areal infection control unit. The hospitals were provided feedback of the results and HAI prevention methods.

Findings

In 2015, 2218 patients from 22 hospitals and in 2017, 2343 patients from 25 hospitals were studied. The prevalence of HAI was 11% in both surveys (ranges per hospital 4-24% and 4-31%, respectively). Of all HAIs, 37% originated from referring hospitals. Respiratory tract, urinary tract and skin were the most frequent sites of infection. One fourth of all patients received at least one systemic antimicrobial. The process showed that recognition of HAIs may be difficult for non-experienced ICPs.

Conclusions

The HALT-2 protocol proved useful in introducing HAI surveillance and prevention in primary care hospitals with active patient transfer from other hospitals and relatively high prevalence of HAI and antimicrobial use. For annually repeated surveys, slightly shorter electronic questionnaires are essential.

Five-year point prevalence survey of healthcare-associated infections and antimicrobial use in a Japanese university hospital

Background

Periodic point prevalence surveys (PPSs) provide a method for assessing changes in healthcare-associated infections (HAIs) and antimicrobial use over time. Following the introduction of an antimicrobial stewardship programme at Nagoya University Hospital (Aichi, Japan) a five-year PPS study was performed to highlight any epidemiological changes.

Methods

One-day PPSs were performed annually in July at Nagoya University Hospital. Data on patient characteristics, medical devices, active HAIs and antimicrobial use were collected using a standard data-collection form.

Results

A total of 4339 patients were included. Over the five-year study period the median patient age was 62 years, median duration of hospital admission was nine days, 9% of patients had an HAI and 35.2% received at least one antimicrobial. Overall there were 406 HAIs (95% confidence interval, 369-447) with surgical site infection, pneumonia and febrile neutropenia occurring most frequently. Enterobacterales were the most common pathogens (N = 78, 28.6%) and 32.1% were third-generation cephalosporin-resistant. Meropenem was the most frequently prescribed antimicrobial for HAIs. Surgical antimicrobial prophylaxis changed drastically, with shorter durations and a marked reduction in oral cephalosporin use. However, antimicrobials for medical prophylaxis gradually increased.

Conclusions

This five-year PPS study shows consistent data for patient background, HAIs and causative pathogens and highlights changes in antimicrobial use during the era of the National Action Plan on Antimicrobial Resistance. To describe the epidemiology of Japanese hospitals by PPS, multicentre PPSs including in community hospitals should be performed annually.

Assessing the impact of the Global Point Prevalence Survey of Antimicrobial Consumption and Resistance (Global-PPS) on hospital antimicrobial stewardship programmes: results of a worldwide survey

BACKGROUND

The Global Point Prevalence Survey of Antimicrobial Consumption and Resistance (Global-PPS) provides a methodology to support hospitals worldwide in collecting antimicrobial use data. We aim to evaluate the impact of the Global-PPS on local antimicrobial stewardship (AMS) programmes and assess health care professionals' educational needs and barriers for implementing AMS.

METHODS

A cross-sectional survey was disseminated within the Global-PPS network. The target audience consisted of hospital healthcare workers, involved in local surveillance of antimicrobial consumption and resistance. This included contacts from hospitals that already participated in the Global-PPS or were planning to do so. The survey contained 24 questions that addressed the hospital's AMS activities, experiences conducting the PPS, as well as the learning needs and barriers for implementing AMS.

RESULTS

A total of 248 hospitals from 74 countries participated in the survey, of which 192 had already conducted the PPS at least once. The survey response rate was estimated at 25%. In 96.9% of these 192 hospitals, Global-PPS participation had led to the identification of problems related to antimicrobial prescribing. In 69.3% at least one of the hospital's AMS components was initiated as a result of Global-PPS findings. The level of AMS implementation varied across regions. Up to 43.1% of all hospitals had a formal antimicrobial stewardship strategy, ranging from 10.8% in Africa to 60.9% in Northern America. Learning needs of hospitals in high-income countries and in low-and middle-income countries were largely similar and included general topics (e.g. 'optimising antibiotic treatment'), but also PPS-related topics (e.g. 'translating PPS results into meaningful interventions'). The main barriers to implementing AMS programmes were a lack of time (52.7%), knowledge on good prescribing practices (42.0%), and dedicated funding (39.9%). Hospitals in LMIC more often reported unavailability of prescribing guidelines, insufficient laboratory capacity and suboptimal use of the available laboratory services.

CONCLUSIONS

Although we observed substantial variation in the level of AMS implementation across regions, the Global-PPS has been very useful in informing stewardship activities in many participating hospitals. More is still to be gained in guiding hospitals to integrate the PPS throughout AMS activities, building on existing structures and processes.

Implementation of a multidisciplinary antimicrobial stewardship programme in a Philippine tertiary care hospital: an evaluation by repeated point prevalence surveys

OBJECTIVES

Optimising antimicrobial prescribing in hospitals through antimicrobial stewardship (AMS) is essential in addressing the global threat of antimicrobial resistance. The objective of this study was to evaluate the impact of a hospital-wide programme, delivered by a multidisciplinary AMS team, on antimicrobial prescribing outcomes.

METHODS

The AMS programme consisted of a combination of persuasive, restrictive, and structural components and was implemented in two phases. We used data from the Global-PPS, collected every six months between September 2017 and December 2019, to measure the antimicrobial use prevalence and monitor selected antibiotic prescribing quality indicators.

RESULTS

A significantly increasing trend (P < 0.001) was observed for the indicators related to documentation of prescribing, that is the reason for treatment and stop or review date. We observed a significantly decreasing trend (P < 0.001) in the number of prescriptions for surgical antibiotic prophylaxis (SAP) prescribed for more than 24 h; however, sample sizes for surgical patients were small. For these three indicators, a sudden and pronounced improvement was seen after the second set of interventions, which consisted of (i) an antibiotic documentation policy, (ii) a 24-h automatic stop order for SAP, and (iii) dissemination of new SAP guidelines. A significantly decreasing trend was also observed for hospital-wide antimicrobial use prevalence (P < 0.001).

CONCLUSIONS

The implementation of a multidisciplinary antimicrobial stewardship programme positively influenced antibiotic prescribing practices. Further research should address long-term trends in antibiotic prescribing to establish whether these coordinated activities have led to a sustained behaviour change among prescribers, thereby also evaluating clinical outcomes and antimicrobial resistance rates.

Antibiotic Use Among Hospitalized Children and Neonates in China: Results From Quarterly Point Prevalence Surveys in 2019

Background: Antimicrobial resistance is a significant clinical problem in pediatric practice in China. Surveillance of antibiotic use is one of the cornerstones to assess the quality of antibiotic use and plan and assess the impact of antibiotic stewardship interventions.

Methods: We carried out quarterly point prevalence surveys referring to WHO Methodology of Point Prevalence Survey in 16 Chinese general and children’s hospitals in 2019 to assess antibiotic use in pediatric inpatients based on the WHO AWaRe metrics and to detect potential problem areas. Data were retrieved via the hospital information systems on the second Monday of March, June, September and December. Antibiotic prescribing patterns were analyzed across and within diagnostic conditions and ward types according to WHO AWaRe metrics and Anatomical Therapeutic Chemical (ATC) Classification.

Results: A total of 22,327 hospitalized children were sampled, of which 14,757 (66.1%) were prescribed ≥1 antibiotic. Among the 3,936 sampled neonates (≤1 month), 59.2% (n = 2,331) were prescribed ≥1 antibiotic. A high percentage of combination antibiotic therapy was observed in PICUs (78.5%), pediatric medical wards (68.1%) and surgical wards (65.2%). For hospitalized children prescribed ≥1 antibiotic, the most common diagnosis on admission were lower respiratory tract infections (43.2%, n = 6,379). WHO Watch group antibiotics accounted for 70.4% of prescriptions (n = 12,915). The most prescribed antibiotic ATC classes were third-generation cephalosporins (41.9%, n = 7,679), followed by penicillins/β-lactamase inhibitors (16.1%, n = 2,962), macrolides (12.1%, n = 2,214) and carbapenems (7.7%, n = 1,331).

Conclusion: Based on these data, overuse of broad-spectrum Watch group antibiotics is common in Chinese pediatric inpatients. Specific interventions in the context of the national antimicrobial stewardship framework should aim to reduce the use of Watch antibiotics and routine surveillance of antibiotic use using WHO AWaRe metrics should be implemented.

Development of a web-based application to improve data collection of antimicrobial utilization in the public health care system in South Africa

Objective

Determining antimicrobial utilization patterns in hospitals can be a challenge given personnel and resource constraints with paper-based systems. A web-based application (APP) was developed in South Africa to address this, building on a recent point prevalence survey (PPS) using a paper-based system. Consequently, there was a need to test and evaluate the ease of use of a newly developed app and potential time saving versus paper-based methods for PPS. The findings can be used to further refine the APP.

Methods

The developed app was tested in a large academic public hospital in a PPS in South Africa. During data collection, the app was evaluated for functionality on 35 variables and subsequently refined. After data collection, the app was evaluated in terms of its time-saving potential and ease of use.

Results

181 patient’s files were surveyed across 13 wards in the hospital, with the antimicrobial usage findings similar to the previous paper-based study in the same hospital. The median age for males was 45.5 years and 42 years for females. Overall 80 out of 181 (44%) patients received antibiotics. Whilst 38% (12 out of 31) of patients in the adult surgical ward received antimicrobials, the prevalence was the highest (78%) in the pediatric medical wards. All the data collectors were confident in using the app after training and found the tool is not complex at all to use. In addition, the time taken to plan for the study and to collect data was considerably reduced. Reduced time spent in data collection and analysis is important for timely instigation of quality improvement programs in resource limited settings.

Conclusions

All data collectors would recommend the app for future PPSs. Several concerns with data entry were identified, which have now been addressed. The app development has been successful and is now being deployed across South Africa as part of a national PPS as well as wider.

A nationwide assessment of the burden of healthcare-associated infections and antimicrobial use among surgical patients: results from Serbian point prevalence survey, 2017

BACKGROUND

As the only non-European Union (EU) country, Serbia participated in a second point prevalence survey of healthcare-associated infections (HAIs) and antimicrobial use (AMU) organized by the European Centre for Disease Prevention and Control (ECDC) in the EU countries. Here, we aimed to estimate the prevalence of HAI and AMU in patients who had recently undergone a surgery and to compare risk profile, HAI rates, and AMU among surgical patients and non-surgical patients.

METHODS

A national PPS was performed in 65 Serbian acute-care hospitals, in November 2017. In this paper, the data of 61 hospitals for adult acute-care were analyzed. To ensure the comparability of study design we used the Serbian translation of ECDC case definitions and ECDC PPS protocol. The trained infection control staff, led by a hospital coordinator, reviewed medical records to identify HAI active at the time of the survey and AMU. Only inpatients admitted to the ward before 8 a.m. on the day if the survey were included.

RESULTS

A total of 12,478 patients from 61 hospitals for adult acute-care were eligible for inclusion in this study. Significantly higher proportions of surgical patients were female, belonged to the 60-to-79 age group, and were less severely ill. Also, extrinsic factors (invasive devices, hospitalization at the ICU, and prior antibiotics therapy) were more frequent in surgical patients. Prevalence of HAIs was higher among surgical patients (261/3626; 7.2%) than among non-surgical patients (258/8852; 2.9%) (p < 0.0001). The highest prevalence of all HAIs was noted in patients who had kidney transplantation (4/11; 36.4%), while SSIs were the most prevalent among patients who had peripheral vascular bypass surgery (3/15; 20.0%). Non-surgical patients received treatment for community-acquired infections in significantly higher proportion (2664/8852; 64.3) (p < 0.001). Surgical prophylaxis for more than 1 day was applied in 71.4% of surgical patients.

CONCLUSION

We have provided an insight into the burden of HAIs and AMU among Serbia acute-care hospitals, and highlighted several priority areas and targets for quality improvement.

Antibiotic Prescribing Patterns at COVID-19 Dedicated Wards in Bangladesh: Findings from a Single Center Study

Background

As evidence is mounting regarding irrational and often unnecessary use of antibiotics during the COVID-19 pandemic a cross-sectional Point Prevalence Survey (PPS) (in accordance with WHO guideline) was conducted across COVID-19 dedicated wards in Dhaka Medical College and Hospital (DMCH).

Methodology

Antibiotic usage data were collected from 193 patients at different COVID-19 dedicated wards at DMCH on 11 June 2020. Comparisons in antibiotic usage were made between different groups using Pearson chi-square and Fisher's exact test.

Result

Findings reveal all surveyed patients (100%) were receiving at least one antibiotic with 133 patients (68.91%) receiving multiple antibiotics. Overall, patients presenting with the severe disease received more antibiotics. Third-generation cephalosporins (i.e. ceftriaxone) (53.8%), meropenem (40.9%), moxifloxacin (29.5%), and doxycycline (25.4%) were the four most prescribed antibiotics among surveyed patients. Diabetes mellitus (DM) was independently associated with multiple antibiotic prescribing. Abnormal C-reactive protein (CRP) and serum d-dimer were linked with higher odds of multiple antibiotic prescribing among study patients.

Conclusion

Prevalence of multiple antibiotic prescriptions was high among severely ill patients and those with abnormal CRP and d-dimer levels. Data regarding the quality of antibiotic prescribing were lacking.

A point prevalence survey to assess antibiotic prescribing in patients hospitalized with confirmed and suspected coronavirus disease 2019 (COVID-19)

Background

Earlier studies have reported high antibiotic use in patients hospitalised for coronavirus disease 2019 (COVID-19), resulting in concerns of increasing antimicrobial resistance with increase antibiotic use in this pandemic. Point prevalence survey (PPS) can be a quick tool to provide antibiotic prescribing information to aid antimicrobial stewardship (AMS) activities.

Objectives

To describe antibiotic utilization and evaluate antibiotic appropriateness in COVID-19 patients using PPS.

Methods

Adapting Global-PPS on antimicrobial use, the survey was conducted in COVID-19 wards at 2 centres in Singapore on 22 April 2020 at 0800h. Patients on systemic antibiotics were included and evaluated for antibiotic appropriateness.

Results

Five hundred and seventy-seven patients were screened. Thirty-six (6.2%) patients were on antibiotics and which were started at median of 7 days (inter-quartile rate (IQR), 4, 11) from symptom onset. Fifty-one antibiotics were prescribed in these patients. Overall, co-amoxiclav (26/51, 51.0%) was the most often prescribed antibiotic. Thirty-one out of 51 (60.8%) antibiotic prescriptions were appropriate. Among 20 inappropriate prescriptions, 18 (90.0%) were initiated in patients with low likelihood of bacterial infections. Antibiotic prescriptions were more appropriate when reviewed by infectious diseases physicians (13/31 [41.9%] versus 2/20 [10.0%], p = 0.015), and if reasons for use were stated in notes (31/31 [100.0%] versus 16/20 [80.0%], p = 0.019).

Conclusions

Despite low prevalence of antibiotic use among confirmed and suspected COVID-19 patients at 2 centres in Singapore, there was significant proportion of inappropriate antibiotics use where bacterial infections were unlikely. AMS teams can tailor stewardship strategies using PPS results.

Identifying opportunities for antimicrobial stewardship through a point prevalence survey in an Indian tertiary-care teaching hospital

OBJECTIVES

Unregulated and inappropriate use of antimicrobial agents has been a major driver of antimicrobial resistance with a dangerous impact on health issues in developing nations. We report an audit of antimicrobial use patterns in a tertiary-care teaching hospital in order to identify opportunities for antimicrobial stewardship.

METHODS

A point prevalence survey was conducted to study the use of ten selected antibiotics in various adult inpatient facilities. Patient characteristics as well as indications and patterns of antibiotic prescription were recorded.

RESULTS

A total of 188 patients received any one of the survey antibiotics, accounting for 43% of patients admitted under the study specialties. Of the 188 patients, 59% were admitted in non-intensive care unit settings. The median (interquartile range) duration of hospitalisation during the survey was 8 (4.75) days. Intra-abdominal infections (75; 40%) and respiratory infections (41; 22%) were the most common reasons for admission. Empirical antibiotic use was observed in 66% of patients. Antimicrobial use without any microbiological test was evidenced in 32 patients (17%). Significant differences were noted between medical and surgical specialties in choice of antibiotic, dosage and utilisation of microbiological tests.

CONCLUSIONS

High empirical antibiotic use, poor transition from empirical to rational use, and underutilisation of microbiological tests were noted. The choice of antibiotics differed among specialties. Inappropriate dosing was greater in surgical specialties, especially with aminoglycosides. Adherence to local antibiotic policy, optimal dosing and audit of reserved antibiotic use can be useful approaches to strengthen antimicrobial stewardship programmes.

Electronically assisted surveillance systems of healthcare-associated infections: a systematic review

Background

Surveillance of healthcare-associated infections (HAI) is the basis of each infection control programme and, in case of acute care hospitals, should ideally include all hospital wards, medical specialties as well as all types of HAI. Traditional surveillance is labour intensive and electronically assisted surveillance systems (EASS) hold the promise to increase efficiency.

Objectives

To give insight in the performance characteristics of different approaches to EASS and the quality of the studies designed to evaluate them.

Methods

In this systematic review, online databases were searched and studies that compared an EASS with a traditional surveillance method were included. Two different indicators were extracted from each study, one regarding the quality of design (including reporting efficiency) and one based on the performance (e.g. specificity and sensitivity) of the EASS presented.

Results

A total of 78 studies were included. The majority of EASS (n = 72) consisted of an algorithm-based selection step followed by confirmatory assessment. The algorithms used different sets of variables. Only a minority (n = 7) of EASS were hospital-wide and designed to detect all types of HAI. Sensitivity of EASS was generally high (> 0.8), but specificity varied (0.37–1). Less than 20% (n = 14) of the studies presented data on the efficiency gains achieved.

Conclusions

Electronically assisted surveillance of HAI has yet to reach a mature stage and to be used routinely in healthcare settings. We recommend that future studies on the development and implementation of EASS of HAI focus on thorough validation, reproducibility, standardised datasets and detailed information on efficiency.

Point prevalence survey of antimicrobial use in three hospitals in North-Eastern Tanzania

Background

Antimicrobial resistance (AMR) is one of the most urgent global health threats with low-resource countries being disproportionately affected. Targeted interventions require insight in antibiotic prescription practices. A point prevalence survey (PPS) is a well-known tool to get insight in antibiotic dispensing practices in hospitals and identify areas for improvement. Here, we describe the results of a PPS performed in a tertiary, regional and district hospital in Kilimanjaro region in Tanzania.

Methods

A PPS was performed in the Kilimanjaro Christian Medical Centre (KCMC; tertiary hospital), Mawenzi (regional) and St. Joseph (district) hospital in November and December 2016. Antibiotic use in all patients admitted more than 24 h and those undergoing surgery was recorded. All clinical wards were included except the pediatrics. Data from a single ward were collected on the same day.

Results

A total of 399 patients were included in the PPS: 232 patients from KCMC, 94 from Mawenzi hospital and 73 patients from St. Joseph hospital. Overall prevalence of antibiotic use was 44.0%: 38% in KCMC, 59% in Mawenzi and 63% in St. Joseph. Ceftriaxone (n = 94, 29.8%), metronidazole (n = 79, 23.9%) and other antibiotics belonging to the penicillin class (n = 89, 28.3%) were most commonly prescribed. Antibiotics prescribed for surgical prophylaxis were continued for more than 3 days in 57% of cases.

Conclusion

Our study shows a rate of broad-spectrum antibiotic use in Tanzanian hospitals and prolonged surgical antibiotic prophylaxis being a common practice. PPS is an important tool to improve future antibiotic use in Tanzania hospitals.

Antibiotic use in Kenyan public hospitals: Prevalence, appropriateness and link to guideline availability

•

We report findings from a point prevalence survey across 14 Kenyan public hospitals.

•

About half of the hospitalised patients received appropriate antibiotic therapy.

•

Laboratory investigations supported less than 1% of the antibiotic prescriptions.

•

Physical availability of treatment guidelines influenced treatment appropriateness.

•

There is need for context-specific, up-to-date, and accessible treatment guidelines.

Objective

To examine prescription patterns and explore to what extent guidelines are available and how they might influence treatment appropriateness among hospitalised patients in Kenyan hospitals.

Methods

Data on antimicrobial usage were collected from hospitalised patients across 14 Kenyan public hospitals. For each prescription, appropriateness of treatment was defined using available local and international treatment guidelines and through consensus with local medical specialists. Association between appropriate treatment, guideline availability and other possible explanatory factors was explored using univariate and multiple regression analysis.

Results

There were 1675 (46.7%) of the 3590 hospitalised patients on antimicrobials with 3145(94%) of the 3363 antimicrobial prescriptions being antibiotics. Two patients (0.1%), had treatment based on available antibiotic susceptibility tests. Appropriate treatment was assessed in 1502 patients who had a single diagnosis. Of these, 805 (53.6%) received appropriate treatment. Physical availability of treatment guidelines increased the odds of receiving appropriate treatment Odds Ratio 6.44[95% CI 4.81–8.64].

Conclusion

Appropriate antibiotic prescription remains a challenge in Kenyan public hospitals. This may be improved by the availability of context-specific, up-to-date, and readily accessible treatment guidelines across all the departments, and by providing better diagnostic support.

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

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.

A 2-year point-prevalence surveillance of healthcare-associated infections and antimicrobial use in Ferrara University Hospital, Italy

Background

Healthcare-Associated Infections (HAIs) represent one of the leading issues to patient safety as well as a significant economic burden. Similarly, Antimicrobial Use (AMU) and Resistance (AMR) represent a growing threat to global public health and the sustainability of healthcare services.

Methods

A Point Prevalence Survey (PPS) following the 2016 ECDC protocol for HAI prevalence and AMU was conducted at Ferrara University Hospital (FUH). Data were collected by a team of trained independent surveyors in 2016 and 2018. Risk factors independently associated with HAI were assessed by a multivariate logistic regression model.

Results

Of the 1102 patients surveyed, 115 (10.4%) had an active HAI and 487 (44.2%) were on at least 1 systemic antimicrobial agent. Factors independently associated with increased HAI risk were a “Rapidly Fatal” McCabe score (expected fatal outcome within 1 year), presence of medical devices (PVC, CVC, indwelling urinary catheter or mechanically assisted ventilation) and a length of hospital stay of at least 1 week. The most frequent types of HAI were pneumonia, bloodstream infections, and urinary tract infections. Antimicrobial resistance to third-generation cephalosporins was observed in about 60% of Enterobacteriaceae.

Conclusions

The survey reports a high prevalence of HAI and AMU in FUH. Repeated PPSs are useful to control HAIs and AMU in large acute-care hospitals, highlighting the main problematic factors and allowing planning for improvement actions.

Point prevalence survey of antimicrobial use and healthcare-associated infections in Belgian acute care hospitals: results of the Global-PPS and ECDC-PPS 2017

Background

The point prevalence survey of healthcare-associated infections (HAIs) and antimicrobial use organized by the European Centre for Disease Prevention and Control (ECDC-PPS) and the Global Point Prevalence Survey of antimicrobial consumption (Global-PPS) were simultaneously performed in Belgian acute care hospitals in 2017.

Methods

Belgian acute care hospitals were invited to participate in either the ECDC or Global-PPS. Hospital/ward/patient-level data were collected between September-December 2017. All patients present in the wards at 8 a.m. on the day of the PPS were included. The data of the ECDC and Global-PPS on antimicrobial consumption were pooled. Detailed data on HAIs were analysed for ECDC-PPS.

Results

Overall, 110 Belgian acute care hospital sites participated in the ECDC and Global-PPS (countrywide participation rate: 81.4%, 28,007 patients). Overall, a crude prevalence of patients with at least one antimicrobial of 27.1% (95% confidence interval (CI) 26.5-27.6%) was found. The most frequently reported indications were pneumonia (23.2%), urinary tract infections (15.2%) and skin and soft tissue infections (11.9%). The reason for antimicrobial use was recorded for 81.9% of the prescriptions, a stop/review date for 40.8% and compliance with local antibiotic guidelines for 76.6%. In the ECDC-PPS, the crude prevalence of patients with at least one HAI was 7.3% (95%CI 6.8-7.7%). Most frequently reported HAIs were pneumonia (21.6%) and urinary tract infections (21.3%).

Conclusions

HAI and antimicrobial use prevalence remained stable in comparison with the previous PPS (7.1% and 27.4% in 2011 and 2015, respectively). Belgian hospitals should be further stimulated to set local targets to improve antibiotic prescribing and reduce HAI.

Global point prevalence survey of antimicrobial consumption in Brazilian hospitals

BACKGROUND

The inappropriate use of antimicrobials and increased rates of antimicrobial resistance is a challenge all over the world. Although antibiotic stewardship is recommended by the Brazilian government, data regarding antibiotic use in Brazilian hospitals are scarce. The aim of this study was to conduct a point prevalence survey of antimicrobial use in 18 Brazilian hospitals.

METHODS

Eighteen Brazilian hospitals conducted the Global Point Prevalence Survey of Antimicrobial Consumption and Resistance (Global-PPS) in 2017. The study enrolled inpatients on antimicrobials. Data collection included details on the antimicrobial prescriptions. A web-based programme was used for data-entry, validation and reporting. The Global-PPS was developed by the University of Antwerp and bioMérieux provided funding support.

FINDINGS

A total of 1801 patients were evaluated, of which 941 (52.2%) were on antimicrobials. Four hundred (42.5%) patients were given at least two antimicrobials. Out of the 1317 antibacterials for systemic use, 514 (39%) were prescribed for community-acquired infections, 533 (40.5%) for healthcare-associated infections and 248 (18.8%) for prophylactic use. The most frequently used antimicrobials were ceftriaxone (12.8%), meropenem (12.3%) and vancomycin (10.3%). Pneumonia or lower respiratory tract infection was the most common site of infection (29.2%). In general, antimicrobials were given mainly parenterally (91%) and empirically (81.2%).

CONCLUSIONS

A high prevalence of antibiotic use was observed in the 18 Brazilian hospitals. The antibiotics were prescribed mainly empirically. Intravenous broad-spectrum antibiotics were the most frequent antimicrobials used, showing that reinforcement of de-escalation strategy is needed. The Global-PPS data can be very useful for monitoring stewardship programmes and intervention.

Linezolid use in German acute care hospitals: results from two consecutive national point prevalence surveys

Background

Linezolid belongs to a reserve group of antibiotics. In recent years, reports on linezolid resistance in gram-positive cocci have become more frequent. Overuse of linezolid is a relevant factor for resistance development. The objective of this study was to describe current prescription practices of linezolid in German hospitals and identify targets for antimicrobial stewardship interventions.

Methods

We analyzed all linezolid prescriptions from the datasets of the consecutive national point prevalence surveys performed in German hospitals in 2011 and 2016. In both surveys, data on healthcare-associated infections and antimicrobial use were collected following the methodology of the European Centre for Disease Prevention and Control.

Results

Overall, the percentage of linezolid among all documented antimicrobials increased significantly from 2011 to 2016 (p < 0.01). In 2011, 0.3% (119 of 41,539) patients received linezolid, in 2016 this proportion was significantly higher (0.4%; 255 of 64,412 patients; p < 0.01). In 2016, intensive care units (ICUs) were the wards most frequently prescribing linezolid. The largest proportion of patients receiving linezolid were non-ICU patients. Roughly 38% of linezolid prescriptions were for treatment of skin/soft tissue and respiratory tract infections. In 2016, linezolid was administered parenterally in 70% (n = 179) of cases. Multivariable analysis showed that the ward specialty ICU posed an independent risk factor, while Northern and Southwestern regions in Germany were independent protective factors for a high rate of linezolid prescriptions.

Conclusions

In conclusion, we detected potentials for improving linezolid prescription practices in German hospitals. Given the emergence of linezolid resistance, optimization of linezolid use must be a target of future antimicrobial stewardship activities.

Prevalence of healthcare-associated infections and antimicrobial use in China: Results from the 2018 point prevalence survey in 189 hospitals in Guangdong Province

BACKGROUND

Limited data on healthcare-associated infections (HAIs) are available from the developing world, thus a point prevalence survey was conducted to determine the prevalence of HAIs and antimicrobial use in Guangdong Province, China.

METHODS

A standardized methodology for point prevalence surveys on HAIs and antimicrobial use has been developed by the Chinese Nosocomial Infection Control and Quality Improvement Center. The prevalence of HAIs, antimicrobial use, and baseline hospital-level variables were collected in 189 hospitals from June 2017 to May 2018.

RESULTS

Of 5 868 147 patients, 72 976 had one or more HAIs (1.24%), with 82 700 distinct HAIs. The prevalence rates of device-associated infections, including ventilator-associated pneumonia, catheter-associated urinary tract infection, and central line-associated bloodstream infection were 7.92, 2.06, and 0.63 per 1000 catheter-days, respectively. A total of 10 591 (0.18%) HAIs caused by multidrug-resistant organisms were identified. Carbapenem non-susceptibility rates were highest in Acinetobacter species (53.86%) and Pseudomonas aeruginosa (21.60%). Forty-six percent (2 712 258/5 868 147) of inpatients were receiving at least one antimicrobial during this survey.

CONCLUSIONS

This survey indicated the relatively lower prevalence of HAIs but higher antimicrobial using in Guangdong Province compared with other mid to low-income and high-income countries. Further studies are warranted to elucidate which HAI-related indicators are the best measures of HAI performance and thus allow improvements leading to better patient outcomes.

A repeated point prevalence survey of antimicrobial use in specialized cancer care hospital of Pakistan: findings and implications

Background: The extensive use of broad-spectrum antimicrobials in immunocompromised patients is inevitable in situations where culture and sensitivity testing is challenging. However, their overuse leads to an increase in antimicrobial resistance (AMR), which is a growing concern. Method: A repeated point prevalence survey (PPS) was conducted to assess the pattern of antimicrobial prescribing in a specialized cancer care hospital in Pakistan using the methodology employed by the European Centre of Disease Prevention and Control. Results: Out of 313 hospitalized patients, 156 (49.8%) were prescribed one or more antimicrobials, 82 (50.9) in 2017 and 74 (48.7) in 2018. The average bed occupancy in the hospital was 80.3%. Fever in neutropenic patients (20.2%), lower respiratory tract infections (17.8%), and sepsis (14.9%) were the three most common clinical indications. The total number of prescribed antimicrobials was 242, of whom, 41 (16.9%) were given orally and 201 (83.1%) were given parenterally. The most commonly used antimicrobials were piperacillin plus enzyme inhibitor (31.8%), meropenem (7.9%), ceftriaxone (6.2%) and vancomycin (6.2%). Of the total prescribed antimicrobials, 42 (17.3%) antimicrobials were used in surgical departments, 89 (36.8) in adult medical departments, 73 (30.1%) in pediatric medical departments and 38 (15.7) in the intensive care unit (ICU). In addition to these antibacterials, there was relatively high use of antivirals (acyclovir; 4.1%) and antifungals (fluconazole; 3.7%, amphotericin B; 2.9%). Conclusion: The study concluded that broad-spectrum antimicrobial usage in cancer hospitals in Pakistan is high, which can be a risk factor for the emergence of AMR. Repeated PPS is a fruitful way to maintain a focus on inappropriate antimicrobial use and develop pertinent intervention programs targeteing specific issues to improve future use.

A multicenter point prevalence survey of healthcare-associated infections in Pakistan: Findings and implications

BACKGROUND

Healthcare-associated infections (HAIs) are seen as a global public health threat, leading to increased mortality and morbidity as well as costs. However, little is currently known about the prevalence of HAIs in Pakistan. Consequently, this multicenter prevalence survey of HAIs was conducted to assess the prevalence of HAIs in Pakistan.

METHODS

We used the methodology employed by the European Centre for Disease Prevention and Control to assess the prevalence of HAIs in Punjab Province, Pakistan. Data were collected from 13 hospitals using a structured data collection tool.

RESULTS

Out of 1,553 hospitalized patients, 130 (8.4%) had symptoms of HAIs. The most common HAI was surgical site infection (40.0%), followed by bloodstream infection (21.5%), and lower respiratory tract infection (14.6%). The prevalence of HAI was higher in private sector hospitals (25.0%) and among neonates (23.8%) and patients admitted to intensive care units (33.3%). Patients without HAIs were admitted mainly to public sector hospitals and adult medical and surgical wards.

CONCLUSIONS

The study found a high rate of HAIs among hospitals in Pakistan, especially surgical site infections, bloodstream infections, and lower respiratory tract infections. This needs to be addressed to reduce morbidity, mortality, and costs in the future, and further research is planned.

A multicenter point prevalence survey of antibiotic use in Punjab, Pakistan: findings and implications

OBJECTIVES

In line with the recent global action plan for antimicrobial resistance, this is the first time such a comprehensive antimicrobial point prevalence survey has been undertaken in Pakistan, the sixth most populous country.

METHODS

This point prevalence survey (PPS) was conducted in 13 hospitals among 7 different cities of Pakistan. The survey included all inpatients receiving an antibiotic on the day of PPS. A web-based application was used for data entry, validation, and reporting as designed by the University of Antwerp (www.global-pps.com).

RESULTS

Out of 1954 patients, 1516 (77.6%) were treated with antibiotics. The top three most reported indications for antibiotic use were prophylaxis for obstetrics or gynaecological indications (16.5%), gastrointestinal indications (12.6%) and lower respiratory tract infections (12.0%). The top three most commonly prescribed antibiotics were ceftriaxone (35.0%), metronidazole (16.0%) and ciprofloxacin (6.0%). Out of the total indications, 34.2% of antibiotics were prescribed for community-acquired infections (CAI), 5.9% for healthcare-associated infections (HAI), and 57.4% for either surgical or medical prophylaxis. Of the total use for surgical prophylaxis, 97.4% of antibiotics were given for more than one day.

CONCLUSIONS

Unnecessary prophylactic antibiotic use is extremely high, and broad-spectrum prescribing is common among hospitals in Pakistan. There is an urgent need to work on the  national action plan of Pakistan on antibiotic resistance to address this.

Burden of healthcare-associated infections in European acute care hospitals

Point prevalence surveys of healthcare-associated infections (HAI) and antimicrobial use in the European Union and European Economic Area (EU/EEA) from 2016 to 2017 included 310,755 patients from 1,209 acute care hospitals in 28 countries. After national validation, we estimated that 6.5% (cumulative 95% confidence interval (cCI): 5.4-7.8%) patients in acute care hospitals had at least one HAI (country-weighted prevalence). On any given day, 98,166 patients (95% cCI: 81,022-117,484) in acute care hospitals had an HAI; 3.8 million (95% cCI: 3.1-4.5 million) patients acquired an HAI each year. Our study confirmed a high annual number of HAI in healthcare facilities in the EU/EEA.

Development of case vignettes for assessment of the inter-rater variability of national validation teams for the point prevalence survey of healthcare-associated infections and antimicrobial use in European acute care hospitals

BACKGROUND

In 2016-17 the European Centre for Disease Prevention and Control (ECDC) organized the second point prevalence survey (PPS) of healthcare-associated infections (HCAIs) and antimicrobial use in European acute care hospitals. This survey included a validation study to maximize the accuracy of case identification and classification.

AIM

ECDC developed case vignettes to assess the performance of the national validation teams.

METHODS

Case vignettes were developed by two medical doctors with experience in the management of HCAIs and antimicrobial stewardship. The case vignettes were based on actual clinical cases. The distribution of HCAIs among the case vignettes reflected the distribution of HCAIs in the previous PPS. All case vignettes were pilot-tested by three expert raters. Agreement among the expert raters was measured using kappa statistics.

FINDINGS

Sixty case vignettes were developed. Twenty-nine of them were HCAI cases and 31 were cases without an HCAI. The inter-rater reliability using kappa statistics was 0.78 for the presence of HCAI and 0.89 for the antimicrobial use, respectively.

CONCLUSION

The agreement between the expert raters was very good for antimicrobial use and good for the presence of HCAI. Case vignettes can be a tool to support standardization of surveillance, improving the validity and comparability of the data.

Point prevalence survey of antimicrobial prescription in a tertiary hospital in South East Nigeria: A call for improved antibiotic stewardship

OBJECTIVES

Antimicrobial prescribing practices and use contribute to the growing threat of antimicrobial resistance (AMR) to global health. Information on antimicrobial prescribing and use are lacking in most developing countries, including Nigeria. This information is crucial for antimicrobial stewardship programmes, an effective tool in minimising AMR. This study was performed to gather baseline information on antimicrobial prescribing practices in Nigeria.

METHODS

A cross-sectional survey was conducted on all inpatients of a tertiary hospital in South East Nigeria. All patients on admission on the day of the survey formed the study population. A standardised questionnaire, web-based data entry and validation process designed by the University of Antwerp, Belgium, were adopted. Information on basic patient demographics, antimicrobial agents used, indication for treatment, laboratory data prior to treatment and stop/review date was collected.

RESULTS

Of 220 inpatients surveyed, 78.2% were receiving at least one antimicrobial agent. The highest prevalence of antimicrobial use was in the ICU (100%), adult surgical ward (82.9%) and paediatric medical ward (82.9%). Agents used were mainly third-generation cephalosporins (ceftriaxone 25.1%) and nitroimidazole (metronidazole 24.6%). Antimicrobial prescription was empirical (91.1% in medical wards, 96.8% in surgical wards and 100% in ICU). There was limited use of guidelines but clear documentation of stop/review dates and reasons for antimicrobial use.

CONCLUSION

Although a majority of antimicrobial prescriptions were made with indications, they were mostly prescribed empirically and the majority of prescriptions were parenteral formulations. There is a need to develop antibiotic guidelines, to educate prescribers on antimicrobial stewardship and to encourage targeted prescription.

Point prevalence survey of peripheral venous catheter usage in a large tertiary care university hospital in Germany

Background

Bloodstream infections (BSI) are among the most frequently documented healthcare-associated infections (HAI). Central and peripheral venous catheters (CVC and PVC) are relevant risk factors for BSI. Although the risk for BSI is higher for CVC, PVC are utilized more frequently and are therefore relevant in the context of HAI prevention. Robust data on the prevalence of PVC and associated infections in German hospitals are scarce to this date. The objectives of this survey were to estimate the prevalence of PVC and PVC-associated infections on peripheral wards of a large tertiary care hospital in Germany. The collected data may be utilized for a tailored infection prevention intervention in the future.

Methods

A point prevalence survey was conducted on peripheral wards of a tertiary care hospital with more than 3.000 beds. Data were collected between August 2017 and February 2018. Standardized data collection forms were used for collecting ward, patient and PVC-related data. As endpoints, prevalence of patients with PVC, PVC-associated infections and PVC without usage in the 24 h prior to the survey and without documentation of intended usage in the 24 h after the survey (“unused PVC”) were chosen. For data analysis, Kruskal-Wallis test was employed for continuous variables and Chi-squared test or Fisher’s exact test for categorical variables. Multivariable analysis and logistic regression were performed for the endpoint unused PVC.

Results

Data from 2.092 patients on 110 wards were collected. The overall prevalence of patients with PVC was 33%. Infections were recorded in 16 patients. Except one case of BSI, these were all local infections at the site of insertion. Of 725 documented PVC, 77 (11%) were unused PVC. Multivariate analysis and logistic regression revealed wards with the practice of regularly obtaining blood from PVC, PVC with dirty or loose insertion dressing, pediatric ward specialty and last inspection of the PVC more than 1 day ago as significant risk factors for unused PVC.

Conclusions

A substantial proportion of patients presented with a PVC on the day of survey. Too few infections were recorded to allow for more detailed analyses. Various risk factors for unused PVC were identified. We hereby present a solid method to obtain an overview about PVC use and to increase awareness for PVC-associated risks. The limitations of point prevalence surveys have to be recognized.

Comparative point prevalence survey of antimicrobial consumption between a hospital in Northern Ireland and a hospital in Jordan

Background

To assess antimicrobial prescribing in a Northern Ireland hospital (Antrim Area Hospital (AAH)) and compare them with those of a hospital in Jordan (Specialty Hospital).

Methods

Using the Global-PPS approach, the present study surveyed patients admitted to the hospital in 2015, the prescribed antibiotics, and a set of quality control indicators related to antibiotics.

Results

Ultimately, 444 and 112 inpatients in the AAH and the Specialty Hospital, respectively, were surveyed. For the medical group, 165 inpatients were prescribed 239 antibiotics in the AAH, while 44 patients in the Specialty Hospital were prescribed 65 antibiotics. In relation to the surgical group, 34 inpatients treated for infection were prescribed 66 antibiotics in the AAH, while 41 patients in the Specialty Hospital treated for infection were prescribed 56 antibiotics. For the medical patients, the most frequently prescribed antibiotics in the AAH were a combination of penicillins (18.8%) and penicillins with extended spectrum (18.8%). For the surgical patients, the most frequently prescribed antibiotics in the AAH were imidazole derivatives (24.2%). For the medical and surgical patients in the Specialty Hospital, the most frequently prescribed antibiotics were third-generation cephalosporins (26.2 and 37.5%, respectively). In medical patients, compliance to guidelines was 92.2% in the Specialty Hospital compared to 72.0% in the AAH (p < 0.001). In surgical patients, compliance to guidelines was 92.7% in the Specialty Hospital compared to 81.8% in the AAH (p = 0.012).

Conclusions

The present study highlighted differences in the utilisation of antimicrobials between two hospitals in two distinct regions and benchmarked antibiotic prescriptions across two hospitals.

Point prevalence survey of antibiotic use in 26 Saudi hospitals in 2016

OBJECTIVE

To evaluate the antibiotic prescribing trends, qualitatively and quantitatively, among Saudi Ministry of Health (MOH) hospitals.

METHOD AND MATERIALS

In May 2016, information about the hospitals and patients was collected for all inpatients from 26 MOH hospitals in Saudi Arabia. Additional information about antibiotic treatment and infections was gathered. Data collection was done using Global Point Prevalence Survey (PPS) tool designed by University of Antwerp, Belgium.

RESULTS

A total of 3240 antibiotic doses were administrated to 2182 patients who represented 46.9% of the total eligible admitted patients. Of those patients on antibiotics, 510 (24%) patients were in the Intensive Care Unit (ICU), 646 (30.4%) patients were medically treated, and 972 (45.7%) patients were in surgical departments. The most commonly prescribed antibiotic group was third-generation cephalosporin (17.2%) and the most frequent indication was respiratory ract infectiont (n=597; 18.2%). Antibiotics for surgical prophylaxis represented 23.4% of the total antibiotic doses. Of those, 78% were administrated for more than 24hs. The rate of adherence to antibiotic guidelines was 48.1%. The indications for antibiotics were not documented in the patients' notes for 51.1% of the prescriptions.

CONCLUSION

This national PPS provided a useful tool to identify targets for quality improvement in order to enhance the prudent use of antibiotics in hospital settings. This survey can provide a background to assess the quality of antibiotic utilisation after any intervention by administering it regularly.

Antifungal consumption, indications and selection of antifungal drugs in paediatric tertiary hospitals in Turkey: Results from the first national point prevalence survey

OBJECTIVES

The aim of this point prevalence survey was to evaluate the consumption, indications and strategies of antifungal therapy in the paediatric population in Turkey.

METHODS

A point prevalence study was performed at 25 hospitals. In addition to general data on paediatric units of the institutes, the generic name and indication of antifungal drugs, the presence of fungal isolation and susceptibility patterns, and the presence of galactomannan test and high-resolution computed tomography (HRCT) results were reviewed.

RESULTS

A total of 3338 hospitalised patients were evaluated. The number of antifungal drugs prescribed was 314 in 301 patients (9.0%). Antifungal drugs were mostly prescribed in paediatric haematology and oncology (PHO) units (35.2%), followed by neonatal ICUs (NICUs) (19.6%), paediatric services (18.3%), paediatric ICUs (PICUs) (14.6%) and haematopoietic stem cell transplantation (HSCT) units (7.3%). Antifungals were used for prophylaxis in 147 patients (48.8%) and for treatment in 154 patients (50.0%). The antifungal treatment strategy in 154 patients was empirical in 77 (50.0%), diagnostic-driven in 29 (18.8%) and targeted in 48 (31.2%). At the point of decision-making for diagnostic-driven antifungal therapy in 29 patients, HRCT had not been performed in 1 patient (3.4%) and galactomannan test results were not available in 12 patients (41.4%). Thirteen patients (8.4%) were receiving eight different antifungal combination therapies.

CONCLUSION

The majority of antifungal drugs for treatment and prophylaxis were prescribed in PHO and HSCT units (42.5%), followed by ICUs. Thus, antifungal stewardship programmes should mainly focus on these patients within the availability of diagnostic tests of each hospital.

Point prevalence surveys of antimicrobial use among eight neonatal intensive care units in India: 2016

BACKGROUND

Information about antimicrobial use is scarce and poorly understood among neonatal intensive care units (NICUs) in India. In this study, we describe antimicrobial use in eight NICUs using four point prevalence surveys (PPSs).

METHODS

As part of the Global Antimicrobial Resistance, Prescribing, and Efficacy in Neonates and Children (GARPEC) study, one-day, cross-sectional, hospital-based PPSs were conducted four times between 1 February 2016 and 28 February 2017 in eight NICUs. Using a standardized web-based electronic data entry form, detailed data were collected for babies on antimicrobials.

RESULTS

A total of 403 babies were admitted to NICUs across all survey days, and 208 (51.6%) were prescribed one or more antimicrobials. Among 208 babies, 155 (74.5%) were prescribed antimicrobials for treatment of an active infection. Among 155 babies with an active infection, treatment was empiric in 109 (70.3%). Sepsis (108, 49.1%) was the most common reason for prescribing antimicrobials. Amikacin (17%) followed by meropenem (12%) were the two most commonly prescribed antimicrobials. For community-acquired sepsis, piperacillin-tazobactam (17.5%) was the most commonly prescribed drug. A combination of ampicillin and gentamicin was prescribed in only two babies (5%).

CONCLUSIONS

The recommended first-line antimicrobial agents, ampicillin and gentamicin, were rarely prescribed in Indian NICUs for community acquired neonatal sepsis.

Development and evaluation of a website for surveillance of healthcare-associated urinary tract infections in Australia

Phase II of the Surveillance to Reduce Urinary Tract Infections project piloted a website for point prevalence surveys of healthcare-associated (HAUTI) and catheter-associated urinary tract infection in Australian hospitals and aged care homes. This report describes development and evaluation of the website for online data collection. Evaluation findings from 38 data collectors indicated that most respondents found website registration and web form use easy (N = 22; 58% and N = 16; 43%, respectively). The need for improved computer literacy skills and automated data systems were highlighted. This study demonstrated a novel approach for Australian HAUTI data collection; however, refinements are needed before national roll-out.

Point prevalence surveys on healthcare acquired infections in medical and surgical wards of a teaching hospital in Rome

BACKGROUND

Healthcare acquired infections (HAI) are an important cause of morbidity and mortality in hospitals worldwide. Aim of the study was to analyze nine years surveillance activity, carried out by point prevalence surveys from 2007 to 2015, in a 450-bed teaching hospital in Rome.

METHODS

Point prevalence surveys were carried out every year in the medical and surgical wards following the same methodology. In accordance with definitions used by the Centers for Disease Control, all infections occurred more than 48 hours after hospital admission were considered HAI, and included in the study. Baseline characteristics, clinical features, isolated pathogens (only for the period 2011-2015) and antimicrobial resistance were recorded.

RESULTS

During the nine years point prevalence surveys a total 2,840 patients were enrolled. Overall 136 (4.79%) patients developed 180 (6.34%) HAI. The most frequent HAI were respiratory tract infections (RTI), which accounted for 35.0% of all HAI, followed by surgical site infections (SSI) 22.2%, urinary tract infections (UTI) 19.4%, bloodstream infections (BSI) 17.2%, and others 6.1%. HAI related to major invasive risk procedures were also evaluated. SSI/patients undergoing surgery 3.99%, UTI/ patients with urinary catheter 4.17% and BSI/patients with CVC 9.42%. Over one-half of all patients surveyed (1,532, 53.9%) were receiving antibiotics at the time of our study. Among them 892 (58.2%) for treatment, 641 (41.8%) for prophylaxis. In the latter group, 109 (17.0%) underwent extra-short term, 89 (13.9%) short term and 443 (69.1%) a long term prophylaxis. During the period 2011-2015 out of 110 HAI episodes 71 (64.5%) were confirmed microbiologically. In total 106 pathogens were isolates, Gram-negative bacteria (63.2%) were isolated more frequently than Gram-positive bacteria (28.3%).

CONCLUSIONS

The overall HAI prevalence in our hospital was consistent with those reported in other studies in Italy. The study underlined the role of Gram-negative bacteria in HAI and the need for antimicrobial stewardship. It also provided useful baseline data for rational priorities in allocation of resources, for further infection control activities.

Antimicrobial prophylaxis outside the operating theatre, an audit in a university hospital

Background

The prophylactic use of antimicrobial agents to prevent infections in non-surgical situations has hardly been investigated. We investigate the extent, indications and appropriateness of antimicrobial prophylaxis given outside the operating room in a tertiary care hospital.

Methods

Four point-prevalence surveys were conducted in which all inpatients on that day were screened for the use of prophylactic antimicrobials: medical prophylaxis, prophylaxis around non-surgical interventions and surgical prophylaxis given on the ward. The primary endpoint was the extent of prophylaxis relative to the total number of antimicrobial prescriptions. We also investigated per prescription the presence of a (local) protocol and adherence to these protocols.

Results

We registered in total 1020 antimicrobial prescriptions, of which 317 (31.1%) were given as prophylaxis. 827/1020 were antibiotic prescriptions. Of these antibiotic prescriptions, 17.0% was medical prophylaxis, 2.7% prophylaxis around non-surgical interventions and 6.9% surgical prophylaxis administered on a ward. For medical antibiotic prophylaxis, a protocol was present in 125 of 141 prescriptions (88.7%); the protocol was followed in 118 cases (94.4%). For prophylaxis around non-surgical interventions and surgical prophylaxis on the wards, protocol presence and adherence rates were 59.1% and 92.3%, and 73.3% and 97.6% respectively. Of the 96 antiviral and 97 antifungal prescriptions, 42.7% and 57.8%, respectively, were medical prophylaxis, of which 95.1 and 96.3% were prescribed according to protocols respectively.

Conclusions

Antimicrobial prophylaxis outside the operating theatre is responsible for a considerable part of total in-hospital antimicrobial use. For most prescriptions there was a protocol and adherence to the protocols was high. The main targets for improvement were prophylaxis around non-surgical interventions and surgical prophylaxis given on the ward.
