Infection control systems in transition: the challenges for post-Soviet Bloc countries

Polish infection control nurses' job satisfaction and cooperation with their colleagues reflect how the value of infection control is appreciated by other health care workers: findings from surveys conducted before and during the COVID-19 pandemic

BACKGROUND

Infection prevention and control (IPC) is based on the activity of specialized, trained and highly qualified personnel, especially infection control nurses (ICNs). Effective implementation of IPC procedures demands close cooperation between IPC teams (IPCTs) and hospital personnel. Based on disturbing results on the epidemiology of health care-associated infections (HAIs) and compliance with preventive procedures, we suspect that cooperation between ICNs and different groups of hospital staff is poor. The aim of this study was to assess the perceptions of ICNs working in Polish hospitals with regard to difficulties in working with various professional groups in the hospital, their organizational conditions, and their job satisfaction before and after the COVID-19 pandemic.

METHODS

The study was conducted twice, in 2014 and 2021, among ICNs working in Polish hospitals. The survey used an anonymous questionnaire designed by the authors.

RESULTS

In 2014, 183 ICNs participated in the study, and 175 ICNs participated in 2021. The respondents' average age and seniority (duration of work as an ICN) were higher in 2021. Depending on the ward specialty, approximately 30-48.8% of the ICNs had difficulty cooperating with physicians. However, the ICNs declared better cooperation with nurses in various hospital wards and with other professionals. For some groups of hospital staff, there was a negative correlation between poor cooperation and ICNs' job satisfaction. The job satisfaction data were disturbing; for example, more than half of the respondents considered changing jobs, and the lack of a sense of purpose in their work was declared by 29.7% of ICNs in 2014 and by 54.3% of ICNs in 2021.

CONCLUSIONS

Our results suggest that infection prevention and control is not highly appreciated by health care workers and hospital management. Our study reveals difficulties in ICNs' cooperation with hospital staff and managers in both 2021 and 2014, moderate job satisfaction, a high level of willingness to change jobs, and insufficient training in interpersonal skills and the implementation of changes. These findings clearly indicate an urgent need to introduce modern competence development systems in infection control beyond the scope of traditional training.

Healthcare-Acquired Infection Surveillance in Neurosurgery Patients, Incidence and Microbiology, Five Years of Experience in Two Polish Units

Introduction: Patients in neurosurgical units are particularly susceptible to healthcare-associated infections (HAI) due to invasive interventions in the central nervous system. Materials and methods: The study was conducted between 2014 and 2019 in neurosurgery units in Poland. The aim of the study was to investigate the epidemiology and microbiology of HAIs and to assess the effectiveness of surveillance conducted in two hospital units. Both hospitals ran (since 2012) the unified prospective system, based on continuous surveillance of HAIs designed and recommended by the European Centre for Disease Prevention and Control (protocol version 4.3) in the Healthcare-Associated Infections Surveillance Network (HAI-Net). In study hospitals, HAIs were detected by the Infection Prevention Control Nurse (IPCN). The surveillance of healthcare infections in hospital A was based mainly on analysis of microbiological reports and telephone communication between the epidemiological nurse and the neurosurgery unit. HAI monitoring in hospital B was an outcome of daily personal communication between the infection prevention and control nurse and patients in the neurosurgery unit (HAI detection at the bedside) and assessment of their health status based on clinical symptoms presented by the patient, epidemiological definitions, microbiological and other diagnostic tests (e.g., imaging studies). In hospital A, HAI monitoring did not involve personal communication with the unit but was rather based on remote analysis of medical documentation found in the hospital database. Results: A total of 12,117 patients were hospitalized. There were 373 HAIs diagnosed, the general incidence rate was 3.1%. In hospital A, the incidence rate was 2.3%, and in hospital B: 4.8%. HAI types detected: pneumonia (PN) (n = 112, 0.9%), (urinary tract infection (UTI) (n = 108, 0.9%), surgical site infection (SSI) (n = 96, 0.8%), bloodstream infection (BSI) (n = 57, 0.5%), gastrointestinal system infection (GI) (n = 13, 0.1%), skin and soft tissue (SST) (n = 9, 0.1%). HAI with invasive devices: 44 ventilator-associated pneumonia (VAP) cases (45.9/1000 pds with ventilator); catheter-associated urinary tract infection (CA-UTI): 105 cases (2.7/1000 pds with catheter); central venous catheter (CVC-BSI): 18 cases (1.9/1000 pds with CVC). The greatest differences between studied units were in the incidence rate of PN (p < 0.001), UTI (p < 0.001), and SSI (p < 0.05). Conclusions: The way HAIs are diagnosed and qualified and the style of work of the infection control team may have a direct impact on the unit epidemiology with the application of epidemiological coefficients. Prospective surveillance run by the infection prevention and control nurse in hospital B could have been associated with better detection of infections expressed in morbidity, especially PN and UTI, and a lower risk of VAP. In hospital A, the lower incidence might have resulted from an inability to detect a UTI or BSI and less supervision of VAP. The present results require further profound research in this respect.

Consumption of Antibiotics and Epidemiology of Clostridioides difficile in the European Union in 2016-Opportunity for Practical Application of Aggregate ECDC Data

Background: The most important pathomechanism of Clostridioides difficile infections (CDI) is post-antibiotic intestinal dysbiosis. CDI affects both ambulatory and hospital patients. Aim: The objective of the study was to analyze the possibility of utilizing databases from the European Centre for Disease Prevention and Control subject to surveillance for the purpose of identifying areas that require intervention with respect to public health. Methods: The analysis encompassed data concerning CDI incidence and antibiotic consumption expressed as defined daily doses (DDD) and quality indicators for antimicrobial-consumption involving both ambulatory and hospital patients in 2016. Results: In 2016, in the European Union countries, total antibiotic consumption in hospital and outpatient treatment amounted to 20.4 DDD (SD 7.89, range 11.04–39.69); in ambulatory treatment using average of ten times more antibiotics than hospitals. In total, 44.9% of antibiotics used in outpatient procedures were broad-spectrum antibiotics. We have found a significant relationship between the quality of antibiotics and their consumption: The more broad-spectrum antibiotics prescribed, the higher the sales of antibiotics both in the community sector and in total. CDI incidence did not statistically significantly correlate with the remaining factors analyzed on a country-wide level. Conclusion: Antibiotic consumption and the CDI incidence may depend on many national variables associated with local systems of healthcare organization and financing. Their interpretation in international comparisons does not give clear-cut answers and requires caution.

Multimodal strategy in surgical site infections control and prevention in orthopaedic patients - a 10-year retrospective observational study at a Polish hospital

Introduction

Surgical site infections (SSIs) are among the most common healthcare-associated infections. They are associated with longer post-operative hospital stays, additional surgical procedures, risk of treatment in intensive care units and higher mortality.

Material and methods

SSIs were detected in patients hospitalized in a 40-bed orthopaedics ward in 2009–2018. The total number of study patients was 15,678. The results were divided into two 5-year periods before and after the introduction of the SSI prevention plan. The study was conducted as part of a national Healthcare-Associated Infections Surveillance Programme, following the methodology recommended by the HAI-Net, European Centre for Disease Prevention and Control Program (ECDC).

Results

One hundred sixty eight SSIs were detected in total, including 163 deep SSIs (SSI-D). The total SSI incidence rate was 1.1%, but in hip prosthesis: 1.2%, in knee prosthesis: 1.3%, for open reduction of fracture (FX): 1.3%, for close reduction of fracture (CR): 1.5, and 0.8% for other procedures. 64% of SSI-D cases required rehospitalisation. A significantly reduction in incidence was found only after fracture reductions: FX and CR, respectively 2.1% vs. 0.7% (OR 3.1 95%CI 1.4–6.6, p < 0.01) and 2.1 vs. 0.8% (OR 2.4 95%CI 1.0–5.9, p < 0.05). SSI-Ds were usually caused by Gram-positive cocci, specially Staphylococcus aureus, 74 (45.7%); Enterobacteriaceae bacillis accounted for 14.1% and Gram-negative non-fermenting rods for 8.5%.

Conclusions

The implemented SSI prevention plan demonstrated a significant decrease from 2.1 to 0.7% in SSI-D incidence only in fracture reductions, without changes in epidemiology SSI incidence rates in other procedures. Depending on the epidemiological situation in the ward, it is worthwhile to surveillance of SSIs associated to different types of orthopaedic surgery to assess the risks of SSI and take preventive measures.

Implementing an infection control and prevention program decreases the incidence of healthcare-associated infections and antibiotic resistance in a Russian neuro-ICU

Background

The impact of infection prevention and control (IPC) programs in limited resource countries such as Russia are largely unknown due to a lack of reliable data. The aim of this study is to evaluate the effect of an IPC program with respect to healthcare associated infection (HAI) prevention and to define the incidence of HAIs in a Russian ICU.

Methods

A pioneering IPC program was implemented in a neuro-ICU at Burdenko Neurosurgery Institute in 2010 and included hand hygiene, surveillance, contact precautions, patient isolation, and environmental cleaning measures. This prospective observational cohort study lasted from 2011 to 2016, included high-risk ICU patients, and evaluated the dynamics of incidence, etiological spectrum, and resistance profile of four types of HAIs, including subgroup analysis of device-associated infections. Survival analysis compared patients with and without HAIs.

Results

We included 2038 high-risk patients. By 2016, HAI cumulative incidence decreased significantly for respiratory HAIs (36.1% vs. 24.5%, p-value = 0.0003), urinary-tract HAIs (29.1% vs. 21.3%, p-value = 0.0006), and healthcare-associated ventriculitis and meningitis (HAVM) (16% vs. 7.8%, p-value = 0.004). The incidence rate of EVD-related HAVM dropped from 22.2 to 13.5 cases per 1000 EVD-days. The proportion of invasive isolates of Klebsiella pneumoniae and Acinetobacter baumannii resistant to carbapenems decreased 1.7 and 2 fold, respectively. HAVM significantly impaired survival and independently increasing the probability of death by 1.43.

Conclusions

The implementation of an evidence-based IPC program in a middle-income country (Russia) was highly effective in HAI prevention with meaningful reductions in antibiotic resistance.

Epidemiology of Ventilator-Associated Pneumonia, microbiological diagnostics and the length of antimicrobial treatment in the Polish Intensive Care Units in the years 2013-2015

Background

Ventilator-associated pneumonia (VAP) is a common nosocomial infection in intensive care units (ICUs). The objective of this study was to describe the epidemiology and microbiology of VAP in Polish ICUs from 2013 to 2015, as well as to understand how these depended on the diagnostic methods used to identify VAP pathogens and the clinical strategy for VAP treatment.

Methods

This observational study was carried out in seven Polish adult ICUs. VAP surveillance was based on the European Healthcare-associated Infections Surveillance Network recommendations and was defined as pneumonia occurring more than 48 h after receiving mechanical ventilation, with symptom onset 3 days or more after the hospital stay. Depending on the microbiological diagnostic method, VAP cases were classified as PNEU-1 (positive quantitative culture from minimally contaminated lower respiratory tract specimen such as broncho-alveolar lavage, protected brush or distal protected aspirate) or other VAP cases.

Results

The incidence of VAP was 8.0% and the incidence density: 12.3/1000 ventilator days. Microbiological diagnosis was made using PNEU-1 in 80 cases (39%); over the study duration, the proportion of cases diagnosed with PNEU-1 increased from 14 to 60% (p < 0.001). The predominant etiologic agents causing VAP were Enterobacteriaceae (32.6%) and non-fermenting Gram-negative bacteria (27.6%). The causative microbe varied significantly depending on the diagnostic method: in cases diagnosed using PNEU-1, Staphylococcus aureus (21.3%) and Klebsiella pneumoniae (12.5%) were the dominant organisms, whereas in other VAP cases, Acinetobacter baumannii (23.8%) was commonly observed. The length of antibiotic treatment in cases diagnosed with PNEU-1 was shorter than for other VAP cases (7.2 vs. 9.1 days, p < 0.005), as was the duration of hospitalization (49 vs. 51.8 days, p < 0.001). Antibiotic resistance was a particular concern for A.baumannii isolates, which were highly resistance to imipenem (70.6%) and meropenem or doripenem (52.9%). K. pneumoniae isolates demonstrated resistance to ampicillin (90.3%), ceftazidime (71.0%) and third-generation cephalosporins (74.2%).

Conclusion

A change over time was observed in the microbiological diagnostic methods used for patients with VAP. A. baumannii was observed mainly in VAP cases diagnosed using substandard methods (non-PNEU-1). The duration of treatment for VAP patients diagnosed properly using PNEU-1 was shorter.

Survey on patient safety culture in the Republic of Moldova: a baseline study in three healthcare settings

BACKGROUND AND AIMS

The Republic of Moldova is a small ex-soviet country in the Central Eastern European group of states, whose official language is Romanian. In countries with limited resources, quality improvement in healthcare and patient safety are very challenging. This study aims to identify which areas of the patient safety culture (PSC) need prompt intervention.

METHODS

A cross-sectional study was conducted in three Moldovan healthcare settings, using the Romanian translation of the US Hospital Survey on Patient Safety Culture HSOPSC. Descriptive statistics were carried out, based on the responses from n. 929 staff. Percentages of positive responses (PPRs) by item (41 items) and composite (12 PSC areas) were computed.

RESULTS

Most respondents were nurses (53%), followed by doctors (35%). The main work areas were: primary care (27%), medical specialties (20%), gynecology and obstetrics (16%), and general surgery (11%). The highest composite PPRs were for: teamwork within units (80%), feedback & communication about error, organizational learning-continuous improvement and supervisor/manager expectations & actions promoting patient safety (78%), and management support for patient safety (75%). The lowest composites were for: frequency of events reported (57%), non-punitive response to errors (53%), communication openness (51%) and staffing (37%).

CONCLUSION

Our results suggest that staffing issues should be tackled to provide safe care. Staff avoid to openly report adverse events and/or discuss errors, likely because a poor understanding of the potential of these events for learning and because of fear of blame or punitive actions. Future research should check psychometrics of the Romanian version of the HSOPSC applied to Moldovan staff.

Incidence, Microbiological Profile and Risk Factors of Healthcare-Associated Infections in Intensive Care Units: A 10 Year Observation in a Provincial Hospital in Southern Poland

Healthcare-associated infections (HAIs) occurring in patients treated in an intensive care unit (ICU) are serious complications in the treatment process. Aetiological factors of these infections can have an impact on treatment effects, treatment duration and mortality. The aim of the study was to determine the prevalence and microbiological profile of HAIs in patients hospitalized in an ICU over a span of 10 years. The active surveillance method was used to detect HAIs in adult patients who spent over 48 h in a general ICU ward located in southern Poland between 2007 and 2016. The study was conducted in compliance with the methodology recommended by the Healthcare-associated Infections Surveillance Network (HAI-Net) of the European Centre for Disease Prevention and Control (ECDC). During the 10 years of the study, 1849 patients hospitalized in an ICU for a total of 17,599 days acquired 510 with overall HAIs rates of 27.6% and 29.0% infections per 1000 ICU days. Intubation-associated pneumonia (IAP) posed the greatest risk (15.2 per 1000 ventilator days), followed by CLA-BSI (8.0 per 1000 catheter days) and CA-UTI (3.0 per 1000 catheter days). The most common isolated microorganism was Acinetobacter baumannii (25%) followed by Coagulaase-negativ staphylococci (15%), Escherichia coli (9%), Pseudomonas aeruginosa (8%), Klebsiella pneumoniae (7%), Candida albicans (6%). Acinetobacter baumannii in 87% and were classified as extensive-drug resistant (XDR). In summary, in ICU patients pneumonia and bloodstream infections were the most frequently found. Acinetobacter baumannii strains were most often isolated from clinical materials taken from HAI patients and showed resistance to many groups of antibiotics. A trend of increasing resistance of Acinetobacter baumannii to carbapenems was observed.

Poor Hand Hygiene Procedure Compliance among Polish Medical Students and Physicians-The Result of an Ineffective Education Basis or the Impact of Organizational Culture?

Objective: The objective of the study was to examine the knowledge of Polish physicians and medical students about the role of hand hygiene (HH) in healthcare-associated infection (HAI) prevention. Study design: A survey was conducted using an author-prepared questionnaire, which was filled out on the first day of hospital work (or internship) by newly admitted physicians who had worked in other hospitals and students of different medical schools in Poland. Methods: 100 respondents participated in the study: 28 students, 18 medical interns and 54 physicians. Results: As many as 3/4 of physicians and students did not use the HH techniques correctly. The respondents declared that they perform HH in the following situations: 74.4% of respondents before an aseptic task; 60.8% before patient contact; 57.0% after patient contact; 11.5% after body fluid exposure risk, and only two respondents (1.1%) after contact with patient surroundings. 64% of respondents declared that their supervisor checked their knowledge of the HH technique when they were touching patients, but their supervisors checked the five instances for HH only in the case of 27 respondents (27%). Students experienced any control of HH in the workplace less often. Interns and physicians mentioned that the most important preventive action in HAI is HH, but for students it is the use of gloves. Conclusions: The level of knowledge and skills of physicians and students in the field of HH is insufficient. Deficiencies in skills and knowledge of HH were identified as early as at the level of the first internship.

Evolution of the Serbian pharmaceutical market alongside socioeconomic transition

INTRODUCTION

South-eastern European socioeconomic transition followed by extensive health systems reforms has completely changed the pharmaceuticals market landscape in the region. Serbia, as the largest Western Balkans market, may serve as an example of such changes.

METHODS

Descriptive trend analysis of national-level dispensing of medicines in Serbia 2004-2012 was performed.

RESULTS

Total public health expenditure in Serbia increased sharply in less than a decade (€1,175,158,679 to €1,847,971,776); public spending on pharmaceuticals doubled (€339,279,304 to €742,013,976). Market growth was primarily driven by statins, novel platelet aggregation inhibitors, monoclonal antibodies and combined preparations indicated in asthma and chronic obstructive pulmonary disease.

CONCLUSION

The pharmaceutical market of Serbia has undergone thorough and complete transformation from within. Serious crisis of medicine supply sustainability is currently shaking Balkan health systems due to increasing public debt worsened by global recession. More responsible reimbursement policy rooted in cost-effectiveness principle is needed in years to come.
