'And you'll suddenly realise 'I've not washed my hands': medical students', junior doctors' and medical educators' narratives of hygiene behaviours

The effectiveness of disinfection protocols in medical school osteopathic manipulative medicine labs

CONTEXT

In light of the COVID-19 pandemic, healthcare-associated infections have taken center stage. Healthcare has adjusted workflows to accommodate for more robust disinfecting regiments to help protect the community. This has resulted in the need for medical institutions to reevaluate the current disinfection protocols down to the student level. The osteopathic manipulative medicine (OMM) laboratory provides an optimal avenue for assessing the effectiveness of medical students' ability to clean examination tables. With OMM laboratories having a high level of interaction, adequate disinfection is important for the health and safety of students and teaching faculties.

OBJECTIVES

This study will evaluate the effectiveness of the current disinfection protocols in the medical school OMM labs.

METHODS

A cross-sectional, nonrandomized study was performed on 20 OMM examination tables utilized for osteopathic training. Tables were chosen based on their close proximity to the podium. Close proximity was utilized as a criteria to increase the probability of utilization by students. The sampled tables were observed to ensure their use by students during class. Initial samples were collected in the morning after disinfection by Environmental Services. Terminal samples were collected after Osteopathic medical students utilized and disinfected the OMM examination tables. Samples were collected from the face-cradle and midtorso regions and analyzed utilizing adenosine triphosphate (ATP) bioluminescence assays with an AccuPoint Advanced HC Reader. This reader provides a digital readout of the quantity of light measured in relative light units (RLUs), which is directly correlated to the amount of ATP present in the sample, providing an estimated pathogen count. For statistical analysis, a Wilcoxon signed-rank test was utilized to find statistical differences in RLUs in samples after initial and terminal disinfection.

RESULTS

The face cradle showed a 40 % increase in failure rate in samples after terminal disinfection when samples were compared after initial disinfection. A Wilcoxon signed-rank test revealed an estimated pathogen level for face cradle that was significantly higher after terminal disinfection (median, 4,295 RLUs; range, 2,269-12919 RLUs; n=20) compared to initial disinfection (median, 769 RLUs; range, 29-2,422 RLUs; n=20), z=-3.8, p=0.00008, with a large effect size, d=2.2. The midtorso region showed a 75 % increase in samples after terminal disinfection when samples were compared after initial disinfection. A Wilcoxon signed-rank test revealed that the estimated pathogen levels for midtorso were significantly higher after terminal disinfecting (median, 656 RLUs; range, 112-1,922 RLUs; n=20) compared to initial disinfecting (median, 128 RLUs; range, 1-335 RLUs; n=20), z=-3.9, p=0.00012, with a large effect size, d=1.8.

CONCLUSIONS

This study suggests that medical students frequently failed to disinfect high-touch regions on examination tables, such as the midtorso and the face cradle. It is recommended that the current OMM lab disinfection protocol be modified to include the disinfection of high-touch regions in order to reduce the possibility of pathogen transmission. Further research should explore the effectiveness of disinfection protocols in clinical settings such as outpatient offices.

Nosocomial bacterial infections in Victoria decreased during the COVID-19 pandemic

Background

A number of infection control interventions were implemented during the COVID-19 pandemic in order to reduce the spread of this virus.

Objective

The purpose of this study was to determine if these interventions were associated with reduced nosocomial bacterial infections in Victoria, Australia.

Methods

Observational data were obtained from the Victorian Healthcare Associated Infection Surveillance System (VICNISS) based on admitted hospital patients in two 6-month timeframes representing pandemic and pre-pandemic hospital practices. Data were collected for surgical site infections, Staphylococcus aureus bacteraemia, Clostridioides difficile infection, and central line-associated bloodstream infections.

Results

There was a significant reduction in the rates of S. aureus bacteraemia (0.74 infections/10, 000 bed days pre-pandemic vs. 0.53/10,000 bed days in the pandemic period [rate ratio 0.72, 95% CI 0.57–0.90]; p = .003) and in C. difficile infections (2.2 infections/10,000 bed days pre-pandemic vs. 0.86/10 000 bed days in the pandemic era [rate ratio 0.76, 95% C.I. 0.67–0.86]; p <.001). There was no change in the overall rate of surgical site infections or central line-associated infections however.

Discussion

The increased emphasis on infection control and prevention strategies during the pandemic period was associated with reduced transmission of S. aureus and C. difficile infections within hospitals.

Understanding Hand Hygiene Behavior in a Public Hospital in Benin Using the Theoretical Domain Frameworks: The First Step for Designing Appropriate Interventions

Background: Hand Hygiene (HH) is widely recognized to be one of the most successful and cost-effective measures for reducing the incidence of healthcare-associated infections (HAIs). The hand hygiene behavior of hospital healthcare workers (HCWs) is not well-documented in Benin. Therefore, Theoretical Domains Framework (TDF) was used to identify the behavioral determinants that may impact HCWs’ hand-hygiene compliance in a public hospital. Methods: A qualitative design comprising face-to-face semi-structured interviews with nine HCWs. The interviews included questions on transmission of infections, hand-hygiene practices, problems with their implementation; and ways to improve hand hygiene compliance. Two pharmacists independently coded interviews into behavioral domains using the TDF and then subdivided them into several themes. Interview transcripts were analyzed following 3-steps approach: coding, generation of specific beliefs, and identification of relevant domains. Results: Almost all interviewees have cited the environmental context and resources (such as lack of water) as a barrier to HH practice. They also believed that role models had a significant impact on the good practices of others HCWs. Fortunately, they were confident of their capabilities to perform appropriate HH behaviors. The majority (7/9) reported having the necessary knowledge and skills and believed they could carry out appropriate HH behavior. In all cases, the participants were motivated to carry out HH behavior, and it was recognized that HH remains the cornerstone to reduce health care associated infections. Conclusion: This study identified several behavioral constructs aligned with the TDF that can be targeted and help for the development of new hand-hygiene interventions. These may increase the likelihood of a successful intervention, thereby improving HH compliance and patient safety, especially in hospitals.

Teaching health care students hand hygiene theory and skills: a systematic review

Hand hygiene is the cornerstone of infection prevention but is poorly undertaken and under-appreciated by medical, nursing, and other health care students. This systematic review aimed to identify and describe strategies used to teach the theory and practice of hand hygiene, determine impact on knowledge and practice, and identify need for future education and research. Ten studies met the criteria for review. Health care students' theoretical knowledge of hand hygiene and their ability to practise are suboptimal and should be improved before they have contact with vulnerable patients. Educational input can increase knowledge and practice but the methodological heterogeneity of the studies and lack of rigour make it impossible to determine which interventions are most likely to be successful. The literature provides little evidence upon which to base educational practice in this area. There is a need for multi-centred longitudinal studies to measure effectiveness of teaching methods over time.

Testing the efficacy and acceptability of video-reflexive methods in personal protective equipment training for medical interns: a mixed methods study

OBJECTIVES

To test the efficacy and acceptability of video-reflexive methods for training medical interns in the use of personal protective equipment (PPE).

DESIGN

Mixed methods study.

SETTING

A tertiary-care teaching hospital, Sydney, January 2018-February 2019.

PARTICIPANTS

72 of 90 medical interns consented to participate. Of these, 39 completed all three time points.

INTERVENTIONS

Participants received a standard infection prevention and control (IPC) education module during their hospital orientation. They were then allocated alternately to a control or video group. At three time points (TPs) over the year, participants were asked to don/doff PPE items based on hospital protocol. At the first two TPs, all participants also participated in a reflexive discussion. At the second and third TPs, all participants were audited on their performance. The only difference between groups was that the video group was videoed while donning/doffing PPE, and they watched this footage as a stimulus for reflexive discussion.

PRIMARY AND SECONDARY OUTCOME MEASURES

The efficacy and acceptability of the intervention were assessed using: (1) comparisons of audit performance between and within groups over time, (2) comparisons between groups on survey responses for evaluation of training and self-efficacy and (3) thematic analysis of reflexive discussions.

RESULTS

Both groups improved in their PPE competence over time, although there was no consistent pattern of significant differences within and between groups. No significant differences were found between groups on reported acceptability of training, or self-efficacy for PPE use. However, analysis of reflexive discussions shows that the effects of the video-reflexive intervention were tangible and different in important respects from standard training.

CONCLUSIONS

Video reflexivity in group-based training can assist new clinicians in engagement with, and better understanding of, IPC in their clinical practice. Our study also highlights the need for ongoing and targeted IPC training during medical undergraduate studies as well as regular workplace refresher training.

Deterioration in hygiene behavior among fifth-year medical students during the placement of intravenous catheters: a prospective cohort comparison of practical skills

BACKGROUND

The American Association of Medical Colleges has defined peripheral intravenous cannulation as one of the eight practical skills that a medical student should possess upon graduation. Since following a standard hygiene protocol can reduce the rate of complications such as bloodstream infections, the medical student's compliance to hygienic standards is highly relevant.

METHODS

This unicentric longitudinal cohort study included 177 medical students undergoing OSCE 1 in the winter semesters 2016/2017 and 2017/2018 as well as OSCE 2 during the winter semesters 2018/2019 and 2019/2020 at the University of Cologne. Their performance in peripheral intravenous cannulation was rated by trained student supervisors using a scaled 13-item questionnaire and compared between OSCE 1 and OSCE 2.

RESULTS

Overall, a decline in the correct placement of peripheral intravenous catheters was observed among advanced medical students during OSCE 2 (mean total score: 6.27 ± 1.84) in comparison to their results in OSCE 1 (mean total score: 7.67 ± 1.7). During OSCE 2, the students were more negligent in regard to hygienic behavior, such as disinfection of the puncture site as well as hand disinfection before and after venipuncture. Their patients were also less likely to be informed about the procedure as compared to OSCE 1.

CONCLUSIONS

An unsatisfying performance in regard to peripheral intravenous cannulation was observed in medical students with hygiene compliance deteriorating between the third and fifth year of their study. Thus, we promote an extension of practical hygiene and stress management training in medical school to reduce complications associated with intravenous catheters, such as bloodstream infections.

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.

Hand hygiene behavior among Sri Lankan medical students during COVID-19 pandemic

BACKGROUND

Poor compliance with hand hygiene practices among medical students poses a risk for cross-infection. It has become more critical during the COVID-19 pandemic than ever before. This study aimed to determine the knowledge, attitudes, practices of hand hygiene among final-year medical students. It also explored reported hand hygiene behavior before the COVID-19 pandemic and the need for educational strategies to correct the deficiencies.

METHODS

A concurrent mixed-method approach was used. In the quantitative strand, a cross-sectional online survey was carried out via a Google form. Mann-Whitney U test and Chi-squared test were used for comparisons. In the qualitative strand, twelve participants were interviewed, based on a semi-structured interview guide and audio recorded. Transcribed data were evaluated with thematic content analysis.

RESULTS

A total of 225 final-year medical students were studied in the quantitative strand. Most were females. The mean score for knowledge was 3.35 ± 0.795 out of six. Of them, 31.6 % of participants scored below 3 points (< 50 % of the total). Most (78.9 %) had positive attitudes (score of > 80 %). Only 36.4 % reported "adequate" hand hygiene performance in all eight dimensions of the behavior domain. Noticeably, fewer participants reported to clean their hands after checking blood pressure (55.6 %), and only 66.2 % stated carrying a hand sanitizer in their pocket. Significant correlations were not found between reported behavior and attitudes (p = 0.821) or knowledge (p = 0.794). The qualitative strand with 12 respondents revealed the positive influence of both hierarchical and non-hierarchal role models. Time constraints, skin irritation, and workload pressures were the main barriers. Frequent reminders, supervision, and interactive teaching were suggested as methods to improve hand hygiene compliance. They also stated that increased enthusiasm was noted on hand hygiene during the COVID-19 pandemic compared to the pre-pandemic period.

CONCLUSIONS

Most of the participants had positive attitudes towards hand hygiene. Yet, a considerable gap between attitudes and knowledge and reported hand hygiene behavior was evident. Coupling educational programs that use cognitive and behavioral methods, including role modeling, supervision, and frequent reminders, is recommended to bridge the knowledge-attitude-behavior gap.

Medical interns' reflections on their training in use of personal protective equipment

BACKGROUND

The current COVID-19 pandemic has demonstrated that personal protective equipment (PPE) is essential, to prevent the acquisition and transmission of infectious diseases, yet its use is often sub-optimal in the clinical setting. Training and education are important to ensure and sustain the safe and effective use of PPE by medical interns, but current methods are often inadequate in providing the relevant knowledge and skills. The purpose of this study was to explore medical graduates' experiences of the use of PPE and identify opportunities for improvement in education and training programmes, to improve occupational and patient safety.

METHODS

This study was undertaken in 2018 in a large tertiary-care teaching hospital in Sydney, Australia, to explore medical interns' self-reported experiences of PPE use, at the beginning of their internship. Reflexive groups were conducted immediately after theoretical and practical PPE training, during hospital orientation. Transcripts of recorded discussions were analysed, using a thematic approach that drew on the COM-B (capability, opportunity, motivation - behaviour) framework for behaviour.

RESULTS

80% of 90 eligible graduates participated. Many interns had not previously received formal training in the specific skills required for optimal PPE use and had developed potentially unsafe habits. Their experiences as medical students in clinical areas contrasted sharply with recommended practice taught at hospital orientation and impacted on their ability to cultivate correct PPE use.

CONCLUSIONS

Undergraduate teaching should be consistent with best practice PPE use, and include practical training that embeds correct and safe practices.

Antibiotic prescribing patterns and knowledge of antibiotic resistance amongst the doctors working at public health facilities of a state in northern India: A cross sectional study

Objectives:

The aim of the study is to understand antibiotic prescribing patterns and to understand knowledge of antibiotic resistance amongst the doctors working at public health facilities of a northern Indian state.

Methodology:

A cross-sectional study among doctors of the civil hospitals of Haryana state of India was conducted 2019. Data were collected by self-administered questionnaire from a total of 215 doctors posted at the 22 district hospitals.

Results:

The response rate was 98%. Doctors (66%) perceived antibiotic resistance as a very important global problem, a very important problem in India (68%) and as an important problem in their hospital (31%). Experience in years was significantly associated with considering hand hygiene (OR, 5.78; 95% CI, 1.6420.3; P = 0.005) and treatment of bacteria as per susceptibility report of the organism (OR, 0.54; 95% CI, 0.310.93; P = 0.03). Surgeons reported piperacillin-tazobactam (17%), cloxacillin (17%), and cephazolin (12.05%) and others (54.2%) as the first choice of antibiotics for infection after surgery. Doctors (52.3%) reported that they started antibiotics 12 hours before surgery; 15 (17%) prescribed antibiotics 6 hours before surgery; and 23 (27%) 1 day before the surgery. Time for stopping antibiotics after surgery, as reported by participants, was 1 day (15%), 23 days (35%), 57 days (44%), respectively. A total of 71 (83%) doctors thought that surgical incision could lead to post-surgical site infection.

Conclusion:

Findings of study can be utilized to enhance education on antimicrobial prescribing, antimicrobial surveillance, and prescribing patterns among doctors in our settings.

Colonization of Methicillin-Resistant Staphylococcus aureus (MRSA) among Medical Students in Tertiary Institution in Central Malaysia

Methicillin-resistant Staphylococcus aureus or MRSA infection is virulent and presents with a broad spectrum of severity. Limited regional reports that specifically outlined the potential risk of medical students being part of the dissemination of MRSA in healthcare settings were noted. This study aims to assess the prevalence and contributory factors of colonization of MRSA on neckties, headscarves, and ID badges among medical students in a local medical university in Malaysia. A cross-sectional study was conducted involving 256 medical students. A validated questionnaire was used to collect the data, and sample swabs were collected between July and August 2013 by swabbing neckties, headscarves, or identification badges. The swabs were then streaked onto mannitol salt agar (MSA) and incubated at 37 °C overnight. Out of 433 samples taken, 40 swabs (9.24%) were positive for Staphylococcus aureus. Out of the 40 swabs, five (12.5%) isolates were MRSA (one culture was isolated from the headscarf of a preclinical student, one culture was isolated from the necktie of clinical students, while the remaining three were isolated from identification badges of clinical students. There was no significant association between age, gender, ethnicity, and phase of medical students with the colonization of MRSA (p > 0.05). There was a significant association between knowledge score on hand hygiene practice and phase of medical students. MRSA colonies were present on neckties, headscarves, and identification badges of medical students of all phases. The findings from this study suggest the need for improvement of hand hygiene knowledge and discontinuity of mandatory use of physical ID badges and neckties among medical students.

Assessing the knowledge, attitudes and perceptions of junior doctors on antimicrobial use and antimicrobial resistance in Greece

OBJECTIVES

Understanding antimicrobial prescribing attitudes and perceptions, especially in the early stages of medical training, is an important driver for appropriate interventions. This study examined junior doctors' knowledge, attitudes and perceptions regarding antimicrobial use and antimicrobial resistance in Greece.

METHODS

A self-administered, internet-based questionnaire survey was completed by trainees and residents of all primary care centres and hospitals in Crete, Greece.

RESULTS

From the 313 invited junior doctors, 214 (68.4%) fully completed the questionnaire. The mean correct knowledge score (four items) was 60%. The highest confidence rates with prescribing were recorded in accurately diagnosing an infection that needs antimicrobial treatment, selecting an appropriate administration route, and selecting the appropriate dosage. The lowest confidence rates were recorded in modifying antimicrobial treatment based on clinical and/or microbiological evidence, prescribing antimicrobial combinations and not prescribing an antimicrobial in a febrile patient without severity criteria and uncertain diagnosis of infection. Use of guidelines and expert consultation were perceived as the most important factors influencing antimicrobial prescribing practices. Most participants were aware of the antimicrobial resistance problem in Greece, and considered excessive prescribing of antimicrobials and broad-spectrum antimicrobials to be the most important causes. Availability of local and national guidelines and antimicrobial resistance data, senior consultation and infectious diseases specialist consultation were the preferred interventions to improve antimicrobial prescribing.

CONCLUSIONS

The findings of this study will contribute to the design of appropriate interventions, based on local evidence, for the establishment of antimicrobial stewardship programs in a country characterised by excessive use of antimicrobials and high resistance rates.

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

Adhering to hygiene standards in daily clinical work is an important characteristic of qualitatively high-value medical care. In this regards, hand hygiene is often focused on in the literature. From the viewpoint of medical education research, we argue that this focus is too narrow to explain how staff who are working clinically with patients implement and adhere to standards of hygiene across a wide variety of tasks of their daily clinical routine. We present basic features of a differentiated concept of hygiene competence, which includes specialized knowledge, corresponding inner attitudes, and action routines that are customized to the needs of specific situations. Building on that, we present a current simulation-based course concept aimed at developing hygiene competence in medical education. Furthermore, we describe a test instrument that is designed according to the principle of a situational judgment test and that appears promising for the assessment of hygiene competence. The course and the measurement instrument are discussed in regards to their fit to the competence model and the related perspectives for research and teaching.

Hand hygiene knowledge and attitude of medical students in western Saudi Arabia

Background

The practice of hand hygiene (HH) has prime importance among Health Care Professionals (HCPs) and non-compliance could cause adverse consequences. By keeping the importance of HH in mind, this study aims at investigating the knowledge and attitudes towards HH among medical students and interns at King Abdulaziz University (KAU), Jeddah, Saudi Arabia (SA).

Methods

The study includes 453 medical students and interns (189 males & 264 females). This study was completed in three months; from September to November 2017. The World Health Organization (WHO) HH questionnaire was used and data were analyzed on SPSS-21.

Results

Two-third of the participants 292 (64.2%) had formal training in HH in the last three years. Almost half of the participants 254 (56.1%) had correct knowledge regarding the major course of transmission of potentially detrimental microbes among patients in the healthcare premises. Just 124 (27.4%) of the respondents had the correct knowledge about the most common basis of germs accountable for healthcare-related infections. Females had significantly better knowledge than males regarding the type of HH technique needed before palpation of the abdomen (177(54%) Vs. 151(46%); P < 0.002), before an injection (175(54.5%) Vs. 146(45.5%); P < 0.007), after emptying a bedpan (207(64.7%) Vs. 113(35.3%); P < 0.001), following discarding examination gloves (256(60.4% Vs. 168(39.6%); P < 0.001] and after exposure to blood (200(64.1%) Vs. 112(35.%); P < 0.001). Female participants had better knowledge than males regarding the type of HH actions. Females also had a significantly better attitude towards the importance of HH than males (240(62.5%) Vs. 144(37.5%); P < 0.001).

Conclusion

The majority of the participants' knowledge regarding HH was not up to the mark; however, female students had better knowledge compared to male students. The medical students and interns' knowledge and positive attitude towards HH can play a pivotal role in preventing HCPs associated infections and it would overall decrease the infection-related burden on the hospital and governmental budgets. It is suggested that multi-dimensional plans are required to change this low compliance to a higher rate.
