Measures of knowledge about standard precautions: A literature review in nursing

Evaluation of Standard Precautions Compliance Instruments: A Systematic Review Using COSMIN Methodology

BACKGROUND

Standard precautions (SPs) are first-line strategies with a dual goal: to protect health care workers from occupational contamination while providing care to infected patients and to prevent/reduce health care-associated infections (HAIs). This study aimed at (1) identifying the instruments currently available for measuring healthcare professionals' compliance with standard precautions; (2) evaluating their measurement properties; and (3) providing sound evidence for instrument selection for use by researchers, teachers, staff trainers, and clinical tutors.

METHODS

We carried out a systematic review to examine the psychometric properties of standard precautions self-assessment instruments in conformity with the COSMIN guidelines. The search was conducted on the databases PubMed, CINAHL, and APA PsycInfo.

RESULTS

Thirteen instruments were identified. These were classified into four categories of tools assessing: compliance with universal precautions, adherence to standard precautions, compliance with hand hygiene, and adherence to transmission-based guidelines and precautions. The psychometric properties of instruments and methodological approaches of the included studies were often not satisfactory. Only four instruments were classified as high-quality measurements.

CONCLUSIONS

The available instruments that measure healthcare professionals' compliance with standard precautions are of low-moderate quality. It is necessary that future research completes the validation processes undertaken for long-established and newly developed instruments, using higher-quality methods and estimating all psychometric properties.

Patient education on infection control: A systematic review

BACKGROUND

Lately, suggestions have been emphasizing the importance of engaging patients and family members in infection control (IC) through participation and education after showing that patients and family members can aid in preventing the transmission of health care-associated infections. However, assessing patient education on IC measures in hospitals is poorly investigated.

PURPOSE

To identify all available studies in the literature that assessed hospitalized patients' education on IC measures.

METHODS

PubMed, Embase, and CINAHL were searched from inception till May 6, 2020 without restrictions. We used Strengthening the Reporting of Observational Studies in Epidemiology tool for assessing the reporting quality of each eligible study.

MAIN FINDINGS

Of the 6,740 identified papers, 25 were eligible for inclusion. Education on health care-associated infections was investigated in 8 studies, education on central line-associated bloodstream infections in 1, education on surgical site infections in 2, education on hand hygiene in 12, education on isolation rationale, precautions, usage of personal protective equipment in 3, and education on respiratory hygiene in 1. In general, a low percentage of patient education on IC was found in most of the included papers.

CONCLUSIONS

The low percentage of patient education on IC in hospitals highlights the need for additional emphasis on patient involvement in IC. Further studies are needed to assess patient education on several IC measures and to explore the education of family members as well.

Adaptation and validation of the Compliance with Standard Precautions Scale amongst nurses in Turkey

AIMS

To adapt and psychometrically test the Compliance with Standard Precautions Scale for use by Turkish nurses.

BACKGROUND

Measurement of standard precautions compliance is important to manage the safety of both patients and health care teams.

METHODS

This two-phase methodological study employed a correlational design with repeated measures. In phase one, the scale's adaptation, including translation, semantic equivalence, content and face validity, was implemented. In phase two, internal consistency and stability were used to examine the reliability of the scale. Construct validity was tested using the Rasch rating scale model. This study was conducted by recruiting 411 nurses from three different hospitals between September 2015 and September 2016.

RESULTS

Adaptation results showed that the Turkish version of the Compliance with Standard Precautions Scale (CSPS-T) is adequate for linguistic and content validation. The content validity index and comprehensibility of the scale were similarly satisfactory. The reliability of the CSPS-T was examined by Cronbach's alpha, corrected item-total correlations and intraclass correlation coefficient, and good results were obtained. The Rasch model showed that all items were compatible with the model. Whereas Item 4 was the most difficult, Item 10 was the easiest.

CONCLUSION

The CSPS-T is a reliable and valid tool for assessing compliance with standard precautions amongst Turkish nurses.

Effective infection prevention and control: the nurse's role

Healthcare-associated infections and antimicrobial resistance are significant threats to public health. As resistant organisms continue to emerge and evolve, and antimicrobial agents become less effective, infection prevention and control remains a vital aspect of maintaining public health, particularly among vulnerable patient groups such as older people and young children. Because of the increasing complexity of healthcare treatments and interventions, patients are becoming increasingly susceptible to healthcare-associated infections and resistant organisms. This article outlines some of the challenges that nurses may experience in ensuring effective infection prevention and control, and how these can be addressed.

Improving adherence to Standard Precautions for the control of health care-associated infections

BACKGROUND

'Standard Precautions' refers to a system of actions, such as using personal protective equipment or adhering to safe handling of needles, that healthcare workers take to reduce the spread of germs in healthcare settings such as hospitals and nursing homes.

OBJECTIVES

To assess the effectiveness of interventions that target healthcare workers to improve adherence to Standard Precautions in patient care.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, CINAHL, LILACS, two other databases, and two trials registers. We applied no language restrictions. The date of the most recent search was 14 February 2017.

SELECTION CRITERIA

We included randomised trials of individuals, cluster-randomised trials, non-randomised trials, controlled before-after studies, and interrupted time-series studies that evaluated any intervention to improve adherence to Standard Precautions by any healthcare worker with responsibility for patient care in any hospital, long-term care or community setting, or artificial setting, such as a classroom or a learning laboratory.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened search results, extracted data from eligible trials, and assessed risk of bias for each included study, using standard methodological procedures expected by Cochrane. Because of substantial heterogeneity among interventions and outcome measures, meta-analysis was not warranted. We used the GRADE approach to assess certainty of evidence and have presented results narratively in 'Summary of findings' tables.

MAIN RESULTS

We included eight studies with a total of 673 participants; three studies were conducted in Asia, two in Europe, two in North America, and one in Australia. Five studies were randomised trials, two were cluster-randomised trials, and one was a non-randomised trial. Three studies compared different educational approaches versus no education, one study compared education with visualisation of respiratory particle dispersion versus education alone, two studies compared education with additional infection control support versus no intervention, one study compared peer evaluation versus no intervention, and one study evaluated use of a checklist and coloured cues. We considered all studies to be at high risk of bias with different risks. All eight studies used different measures to assess healthcare workers' adherence to Standard Precautions. Three studies also assessed healthcare workers' knowledge, and one measured rates of colonisation with methicillin-resistant Staphylococcus aureus (MRSA) among residents and staff of long-term care facilities. Because of heterogeneity in interventions and outcome measures, we did not conduct a meta-analysis.Education may slightly improve both healthcare workers' adherence to Standard Precautions (three studies; four centres) and their level of knowledge (two studies; three centres; low certainty of evidence for both outcomes).Education with visualisation of respiratory particle dispersion probably improves healthcare workers' use of facial protection but probably leads to little or no difference in knowledge (one study; 20 nurses; moderate certainty of evidence for both outcomes).Education with additional infection control support may slightly improve healthcare workers' adherence to Standard Precautions (two studies; 44 long-term care facilities; low certainty of evidence) but probably leads to little or no difference in rates of health care-associated colonisation with MRSA (one study; 32 long-term care facilities; moderate certainty of evidence).Peer evaluation probably improves healthcare workers' adherence to Standard Precautions (one study; one hospital; moderate certainty of evidence).Checklists and coloured cues probably improve healthcare workers' adherence to Standard Precautions (one study; one hospital; moderate certainty of evidence).

AUTHORS' CONCLUSIONS

Considerable variation in interventions and in outcome measures used, along with high risk of bias and variability in the certainty of evidence, makes it difficult to draw conclusions about effectiveness of the interventions. This review underlines the need to conduct more robust studies evaluating similar types of interventions and using similar outcome measures.

Social representations of biosecurity in nursing: occupational health and preventive care

Objective:

to understand the biosecurity social representations by primary care nursing professionals and analyze how they articulate with quality of care.

Methods:

exploratory and qualitative research based on social representation theory. The study participants were 36 nursing workers from primary health care in a state capital in the Northeast region of Brazil. The data were analyzed by descending hierarchical classification.

Results:

five classes were obtained: occupational accidents suffered by professionals; occupational exposure to biological agents; biosecurity management in primary health care; the importance of personal protective equipment; and infection control and biosecurity.

Conclusion:

the different positions taken by the professionals seem to be based on a field of social representations related to the concept of biosecurity, namely exposure to accidents and risks to which they are exposed. However, occupational accidents are reported as inherent to the practice.

Cultural Adaptation and Reliability of the Compliance with Standard Precautions Scale (CSPS) for Nurses in Brazil

Objective:

this study aimed to carry of the cultural adaptation and to evaluate the reliability of the Compliance with Standard Precautions Scale (CSPS) for nurses in Brazil.

Method:

the adaptation process entailed translation, consensus among judges, back-translation, semantic validation and pretest. The reliability was evaluated by internal consistency (Cronbach alpha) and stability (test-retest). The instrument was administered to a sample group of 300 nurses who worked in a large hospital located in the city of São Paulo/SP, Brazil.

Results:

through the semantic validation, the items from the scale were considered understandable and deemed important for the nurse´s clinical practice. The CSPS Brazilian Portuguese version (CSPS-PB) revealed excellent interpretability. The Cronbach`s alpha was 0.61 and the intraclass correlation coefficient was 0.85.

Conclusion:

the initial study showed that CSPS-PB is appropriate to assess compliance with standard precautions among nurses in Brazil. The reliability was considered acceptable. Furhter study is necessary to evaluate its comprehensive psychometric properties.

Compliance with standard precautions among baccalaureate nursing students in a Saudi university: A self-report study

Meticulous observance of standard infection control precautions by health care providers is strongly recommended for every patient encounter. Assessment of nursing students' compliance should be carried out regularly in order to ensure adherence to protocols. Thus, this study was conducted to assess self-reported compliance with standard precautions among baccalaureates in nursing students in a Saudi university. A convenience sample of 236 nursing students was surveyed in this cross-sectional, self-reported study, using the Compliance with Standard Precaution Scale Arabic version (CSPS-A). Independent t-test and one-way analyses of variance (ANOVA) were performed to examine the differences on compliance. A multiple regression analysis was performed to identify the factors affecting compliance. The overall compliance rate was 61.0%. The students reported highest compliance in disposing used sharp instruments and other sharp objects into sharps-only boxes, while the lowest compliance rate in using water only for hand washing. Significant differences in compliance were observed when respondents were grouped according to their demographic characteristics. Cultivating a supportive culture of adherence to infection control precautions among nursing students is of paramount importance. The clinical environment should be supportive of a culture where strict compliance with the control and prevention of infection is of prime importance.

Sociocognitive determinants of self-reported compliance with standard precautions: Development and preliminary testing of a questionnaire with French health care workers

BACKGROUND

Inconsistent compliance of health care workers with standard precautions has already been documented. The objective of this study was to develop a questionnaire to investigate the sociocognitive determinants of compliance with standard precautions based on the theory of planned behavior.

METHODS

To construct the Standard Precautions Questionnaire (SPQ), items were selected using a systematic review of literature and semistructured interviews with 54 health care workers. Thirty-five items were selected for a draft questionnaire. These questionnaires were sent to 649 health care workers in 3 medical specialties (pediatrics, geriatrics, and intensive care) in a French University hospital. A total of 331 valid questionnaires were analyzed.

RESULTS

Factor analysis yielded a final 7-factor solution with an explained variance of 66.51%, with 24 items. The 7 dimensions were the following: attitude toward standard precautions, social influence facilitating organization, exemplary behavior of colleagues, organizational constraints, individual constraints, and intention to perform standard precautions. Some differences were observed between medical specialties on attitude toward standard precautions, social influence, and individual constraints.

CONCLUSION

The SPQ met the conditions of reliability and validity in accordance with psychometric demands and could be used to evaluate attitudes and intention to perform standard precautions among medical and nursing staff.
