Why hand hygiene is not sufficient: modeling hygiene competence of clinical staff as a basis for its development and assessment

COVID-19: Development and implementation of a video-conference-based educational concept to improve the hygiene skills of health and nursing professionals in the Republic of Kosovo

INTRODUCTION

The COVID-19 pandemic caught the health care systems of all countries unprepared. For the further education of healthcare personnel in the Republic of Kosovo, it became necessary to implement a concept for practical training in hygienic working. A video-conference-based educational concept to bridge the physical distance between Germany and Kosovo enabled the rapid, theoretical and practical transfer of knowledge.

METHODS

Current evidence on COVID-19 and Standard Operation Procedures (SOP) were researched. Healthcare staff in Pristina were advised and trained in ten online sessions on hygienic working under pandemic conditions via the "Logitech Rally for DFNconf" video conferencing system. The seminars were interpreted consecutively (Albanian). The Situational Judgement Test (HygiKo-SJT) should describe changes in participants' hygiene knowledge.

RESULTS

A total of 25 people were trained in hygiene-related knowledge in terms of basic and specific hygiene for COVID-19. The weekly training sessions made it possible to address questions and subsequently provide practical knowledge. The HygiKo-SJT did not show a generalizable, measurable improvement in hygiene competence.

CONCLUSION

Participants benefited from the concept and rapid implementation of a live video-conference-based seminar on "Hygiene under Pandemic Conditions". The positive experience in terms of guidance, advice and training provides the basis for implementing a dedicated "Hygiene" module in Kosovo.

Microbial contamination of the hands of healthcare providers in the operating theatre of a central hospital

Background

Effort is invested in maintaining the sterility of the operating field, but less attention is paid to potential healthcare associated infection (HAI) sources through patient contact with non-scrubbed healthcare providers (HCPs). A single microbiological assessment of hands can provide a good assessment of the potential dynamic transmission of microorganisms. The aim of this study was to identify and quantify the microbial growth on the hands of HCPs in the operating theatres of Chris Hani Baragwanath Academic Hospital.

Methods

A prospective, contextual and descriptive study design was followed. Seventy-five samples were collected using convenience sampling from an equal number of surgeons, anaesthetists and nurses. Specimens were taken using agar plates and underwent semi-quantitative analysis.

Results

All the hands of the HCPs displayed growth; 95% grew commensals and 64% grew pathogens. Eighteen commensal microorganisms and 21 pathological microorganisms were noted. Comparisons of commensal, pathological and combined levels of contamination among the three groups were not statistically significant (p = 0.061, p = 0.481, p = 0.236). No significant difference between the growth of combined microorganisms (p = 0.634) and pathological microorganisms (p = 0.499) among the groups. Surgeons had significantly more commensal growth (p = 0.041). There was no statistically significant difference between sexes (p = 0.290).

Conclusion

It was concerning that 100% of the hands of HCPs who were about to commence with the surgical list had microbial growth. These HCPs could have already been in contact with patients and equipment in the theatre environment.

Measuring hygiene competence: the picture-based situational judgement test HygiKo

BACKGROUND

With the onset of the COVID-19 pandemic at the beginning of 2020, the crucial role of hygiene in healthcare settings has once again become very clear. For diagnostic and for didactic purposes, standardized and reliable tests suitable to assess the competencies involved in "working hygienically" are required. However, existing tests usually use self-report questionnaires, which are suboptimal for this purpose. In the present study, we introduce the newly developed, competence-oriented HygiKo test instrument focusing health-care professionals' hygiene competence and report empirical evidence regarding its psychometric properties.

METHODS

HygiKo is a Situational Judgement Test (SJT) to assess hygiene competence. The HygiKo-test consists of twenty pictures (items), each item presents only one unambiguous hygiene lapse. For each item, test respondents are asked (1) whether they recognize a problem in the picture with respect to hygiene guidelines and, (2) if yes, to describe the problem in a short verbal response. Our sample comprised n = 149 health care professionals (79.1 % female; age: M = 26.7 years, SD = 7.3 years) working as clinicians or nurses. The written responses were rated by two independent raters with high agreement (α > 0.80), indicating high reliability of the measurement. We used Item Response Theory (IRT) for further data analysis.

RESULTS

We report IRT analyses that show that the HygiKo-test is suitable to assess hygiene competence and that it allows to distinguish between persons demonstrating different levels of ability for seventeen of the twenty items), especially for the range of low to medium person abilities. Hence, the HygiKo-SJT is suitable to get a reliable and competence-oriented measure for hygiene-competence.

CONCLUSIONS

In its present form, the HygiKo-test can be used to assess the hygiene competence of medical students, medical doctors, nurses and trainee nurses in cross-sectional measurements. In order to broaden the difficulty spectrum of the current test, additional test items with higher difficulty should be developed. The Situational Judgement Test designed to assess hygiene competence can be helpful in testing and teaching the ability of working hygienically. Further research for validity is needed.
