Should automated electronic hand-hygiene monitoring systems be implemented in routine patient care? Systematic review and appraisal with Medical Research Council Framework for Complex Interventions.

Manual hand-hygiene audit is time-consuming, labour-intensive and inaccurate. Automated hand-hygiene monitoring systems (AHHMSs) offer advantages (generation of standardized data, avoidance of the Hawthorne effect). World Health Organization Guidelines for Hand Hygiene published in 2009 suggest that AHHMSs are a possible alternative. The objective of this review was to assess the current state of the literature for AHHMSs and offer recommendations for use in real-world settings. This was a systematic literature review, and publications included were from the time that PubMed commenced until 19th November 2023. Forty-three publications met the criteria. Using the Medical Research Council's Framework for Developing and Evaluating Complex Interventions, two were categorized as intervention development studies. Thirty-nine were evaluations. Two described implementation in real-world settings. Most were small scale and short duration. AHHMSs in conjunction with additional intervention (visual or auditory cue, performance feedback) could increase hand hygiene compliance in the short term. Impact on infection rates was difficult to determine. In the few publications where costs and resources were considered, time devoted to improving hand hygiene compliance increased when an AHHMS was in use. Health workers' opinions about AHHMSs were mixed. In conclusion, at present too little is known about the longer-term advantages of AHHMSs to recommend uptake in routine patient care. Until more longer-term accounts of implementation (over 12 months) become available, efforts should be made to improve direct observation of hand hygiene compliance to improve its accuracy and credibility. The Medical Research Council Framework could be used to categorize other complex interventions involving use of technology to prevent infection to help establish readiness for implementation.

Challenges undertaking procedures requiring asepsis: a qualitative interview study with nurses.

BACKGROUND: Invasive devices and breaches to skin and mucous membranes increase susceptibility to infection. Nurses frequently undertake procedures requiring asepsis (PRAs), but report challenges and unwarranted variations in practice. OBJECTIVE: To explore nurses' experiences, perceived gaps in information and support needed to conduct PRAs. METHODS: Qualitative interviews were undertaken with 20 nurses in the UK National Health Service between September 2021 and January 2022 employing approaches to sampling and data collection adopted in grounded theory. RESULTS: Informants were employed in diverse clinical settings. They thought that outside operating theatres, attempts to maintain asepsis would inevitably be compromised, but that much could still be done to contain the risk of contaminating susceptible sites irrespective of circumstances. Suboptimal practice was reported, and informants were unclear whether asepsis was needed to perform routine procedures (e.g. dressing chronic wounds, manipulating indwelling intravascular lines). Problems were attributed to inadequacies in nursing education, poor access to continuing professional development, and carelessness of junior nurses and medical staff. Informants wanted more detailed guidelines to conduct PRAs. Senior nurses wanted procedures to be conducted in the same way regardless of circumstance. Nurses who undertook PRAs regularly suggested that guidelines should be flexible. CONCLUSION: There is a need for detailed guidelines to inform PRAs, better access to clinical updating, and improvements in pre-registration nursing education. To meet contemporary standards, guideline generation should adopt recognized methodology. Student nurses should be introduced to the knowledge and skills required to undertake and adjust PRAs according to circumstance during simulated practice before contact with real patients.

Research ethics training, challenges, and suggested improvements across Europe: Radiography research ethics standards for Europe (RRESFE).

INTRODUCTION: The Radiography Research Ethics Standards for Europe (RRESFE) project aimed to provide a cross-sectional view of the current state of radiography research ethics across Europe. This included investigating education and training in research ethics, and identifying the key challenges and potential improvements associated with using existing research ethics frameworks. METHODS: This cross-sectional online survey targeting radiography researchers in Europe was conducted between April 26 and July 12, 2021. Descriptive and analytical statistics were used to identify research ethics education and training trends. Content analysis of qualitative responses was employed to identify significant challenges and proposed improvements in research ethics frameworks of practice. RESULTS: There were 232 responses received across 33 European countries. Most (n = 132; 57%) respondents had received some research ethics training; however, fewer participants had received training on safeguarding vulnerable patients (n = 72; 38%), diversity and inclusivity (n = 62; 33%), or research with healthy volunteers (n = 60; 32%). Training was associated with a greater perceived importance of the need for research ethics review (p = 0.031) and with the establishment of EQF Level 6 training (p = 0.038). The proportion of formally trained researchers also varied by region (p = <0.001). Time-to-ethics-approval was noted as the biggest challenge for professionals making research ethics applications. CONCLUSION: Early and universal integration of research-oriented teaching within the radiography education framework which emphasises research ethics is recommended. Additionally, study findings suggest research ethics committee application and approval processes could be further simplified and streamlined. IMPLICATIONS FOR PRACTICE: The survey contributes to a growing body of knowledge surrounding the importance of education and training in research ethics for assuring a high standard of research outputs in Radiography and has identified hurdles to obtaining research ethics approval for further investigation and address.

Research ethics systems, processes, and awareness across Europe: Radiography research ethics standards for Europe (RRESFE).

INTRODUCTION: The Radiography Research Ethics Standards for Europe (RRESFE) project aims to provide a cross-sectional snapshot of current research ethics systems, processes, and awareness of such, across Europe together with identifying the associated challenges, education, and training needs. METHODS: A cross-sectional online survey targeting radiography researchers in Europe was conducted. Data collection took place between April 26 and July 12, 2021, using a snowball sampling approach. Descriptive and analytical statistics were used to identify trends in research ethics frameworks across Europe. RESULTS: 285 responses were received across 33 European and 23 non-European countries. Most (n = 221; 95%) European respondents stated ethics approval is required before commencing research in their country. Requirements around research ethics approval and awareness of such requirements varied by European region (X2 (2, n = 129) = 7.234, p = 0.013) and were found to differ depending on the type of research participant and study design. Additionally, European respondents reported ethics approval is a national requirement more often than their non-European counterparts (X2 (1, n = 282) = 4.316, p = 0.049). Requirements for ethics approval were also associated with the undergraduate programme duration (2-year vs. 3-year vs. 3.5 year vs. 4-year vs. multiple programme durations; X2 (4, n = 231) = 10.075, p = 0.016) and availability of postgraduate training (postgraduate training available vs. postgraduate training not available; X2 (1, n = 231) = 15.448, p = <0.001) within respondents' country. CONCLUSION: Respondents from countries with longer programme durations/availability of multiple programme lengths, availability of postgraduate training, and establishment of European Qualifications Framework Level 6 were generally associated with less uncertainty and more comprehensive research ethics requirements. IMPLICATIONS FOR PRACTICE: Results are informative of the current status of research ethics within evidence-based radiography.

The Hawthorne effect on adherence to hand hygiene in patient care.

Numerous studies demonstrate that the Hawthorne effect (behaviour change caused by awareness of being observed) increases health workers' hand hygiene adherence but it is not clear whether they are methodologically robust, what the magnitude of the effect is, how long it persists or whether it is the same across clinical settings. The objective of this review was to determine the rigour of the methods used to assess the Hawthorne effect on hand hygiene, effect size estimation, variations between clinical settings and persistence. To this end, a systematic literature review with meta-analysis was conducted. Nine studies met the criteria for the review. Methodological quality was variable. The Hawthorne effect ranged from -6.9% to 65.3%. It was 4.2% in one study conducted in intensive care and 16.4% in transplant units. It was most marked when data were collected across an entire hospital and in a group of general hospitals. Differences between wards in the same hospital were apparent. In the two studies where duration was estimated, the Hawthorne effect appeared transient. Despite methodological shortcomings, the review indicates clear evidence of a Hawthorne effect on general wards. There is evidence that it may vary between clinical speciality and across departments. The review identifies a need for standardized methodologies to measure the Hawthorne effect to overcome the dilemma of reporting the potentially inflated rates of adherence obtained through overt audit. Occasional covert audit could give a better estimation of true hand hygiene adherence but its acceptability and feasibility to health workers need to be explored.

Ionising radiation exposure from medical imaging - A review of Patient's (un) awareness.

INTRODUCTION: Medical imaging is the main source of artificial radiation exposure. Evidence, however, suggests that patients are poorly informed about radiation exposure when attending diagnostic scans. This review provides an overview of published literature with a focus on nuclear medicine patients on the level of awareness of radiation exposure from diagnostic imaging. METHODS: A review of available literature on awareness, knowledge and perception of ionising radiation in medical imaging was conducted. Articles that met the inclusion criteria were subjected to critical appraisal using the Mixed Methods Appraisal Tool. RESULTS: 140 articles identified and screened for eligibility, 24 critically assessed and 4 studies included in synthesis. All studies demonstrated that patients were generally lacking awareness about radiation exposure and highlighted a lack of communication between healthcare professionals and patients with respect to radiation exposure. CONCLUSION: Studies demonstrate a need to better inform patients about their radiation exposure, and further studies focusing on nuclear medicine patients are particularly warranted. IMPLICATIONS FOR PRACTICE: Adequate and accurate information is crucial to ensure the principle of informed consent is present.

A meta-synthesis of women's experiences of online forums for maternal mental illness and stigma.

Perinatal mental illness affects 15% of women; however, only half of these women access treatment. Some women with untreated perinatal mental illness may continue to suffer with mental illness after the perinatal period. Evidence suggests that one barrier to accessing treatment is stigma. Forums may provide an acceptable place for women to converse about the stigmatised symptoms of maternal mental illness. Reducing stigma may increase treatment uptake. This study aimed to review and synthesise the qualitative research on maternal mental illness forums and stigma so that stigma can be addressed and treatment improved. A meta-synthesis was conducted to describe and interpret qualitative studies regarding forum use and maternal mental illness stigma. A systematic search of seven electronic databases and Google Scholar was performed. Additional references were collected through screening references of the identified studies. Five studies were identified that reported women's experiences of online forums for maternal mental illness and stigma. The synthesis identified four key themes: (1) a safe place to talk; (2) virtual support; (3) stigma and identity; and (4) repair of the mother identity. Stigma maybe reduced by forum discourse that reconceptualises what is to be a "good mother" and separates stigma and maternal identity. This synthesis provides a novel and more detailed framework for the stigma of maternal mental illness and forum use. This suggests forums may enable women to explore their dual identity and repair their maternal identity, and this may reduce stigma. Healthcare providers could discuss forum use with their clients.

Oral nutrition support interventions for patients who are malnourished or at risk of malnutrition: a survey of clinical practice amongst UK dietitians.

BACKGROUND: Guidance on choosing oral nutritional support strategies varies and the evidence for different approaches is discordant. The present study aimed to examine opinion and practice in the use of oral nutritional support amongst UK dietitians and to assess the factors that influence these clinical decisions. METHODS: The study comprised a cross-sectional, anonymous, national survey of UK dietitians. RESULTS: There were 207 completed responses (3% response rate). More dietitians reported using combined approaches (COMB) [n = 129 (62%)] over food-based (FB) strategies [n = 70 (34%)] or oral nutritional supplements (ONS) alone [n = 8 (4%)] (N = 207, P < 0.001). Intervention choice was associated with clinical setting and clinical speciality; community dietitians reported more frequent use of FB or ONS alone [n = 48 (59%)] versus COMB [n = 34 (41%)] compared to acute dietitians [COMB: n = 83 (78%) COMB versus FB or ONS alone: n = 24 (22%)] (N = 207, P < 0.0001). Specialist nutrition support dietitians reported more frequent use of FB or ONS alone [n = 22 (54%)] versus COMB [n = 19 (46%)] compared to nonspecialists [FB or ONS alone: n = 17 (45%) versus COMB: n = 21 (55%)] and other specialist dietitians [FB or ONS: n = 39 (30%) alone versus COMB: n = 89 (70%)] (P = 0.017). The greatest influences on choice were ease of implementation [n = 192 (93%)], departmental protocols [n = 184 (89%)], professional management pathways [n = 179 (87%)] and published research [n = 165 (80%)]. Patient circumstances [n = 117 (57%) and n = 99 (48%)] and ease of implementation [n = 35 (17%) and n = 48 (24%)] were reported as most influential in the first and second case scenarios, respectively. CONCLUSIONS: There is a need for further research on approaches to the dietetic management of adult malnutrition.

Mental health nurses' encounters with occupational health services.

BACKGROUND: Staff well-being is vital to the functioning of the UK National Health Service (NHS). Mental health nurses (MHNs) with personal experience of mental illness can offer a professionally and personally informed insight into the occupational health (OH) service offered by their employer. AIMS: To investigate MHNs' views of OH provision in the NHS, based on their personal experience. METHODS: A qualitative interview study using a purposive sample of MHNs with personal experience of mental illness. RESULTS: Twenty-seven MHNs met the inclusion criteria. Thematic analysis identified three themes: comparisons of 'relative expertise' between the mental health nurse and the OH clinician; concerns about 'being treated' by a service at their work; and 'returning to work'. CONCLUSIONS: OH provision in mental health settings must take account of the expertise of its staff. Further research, looking at NHS OH provision from the provider perspective is warranted.

Hand hygiene compliance monitoring in anaesthetics: Feasibility and validity.

BACKGROUND: Hand hygiene compliance scores in the anaesthetic department of an acute NHS hospital were persistently low. AIMS: To determine the feasibility and validity of regular accurate measurement of HHC in anaesthetics and understand the context of care delivery, barriers and opportunities to improve compliance. METHODS: The hand hygiene compliance of one anaesthetist was observed and noted by a senior infection control practitioner (ICP). This was compared to the World Health Organization five moments of hand hygiene and the organisation hand hygiene tool. FINDINGS: In one sequence of 55 min, there were approximately 58 hand hygiene opportunities. The hand hygiene compliance rate was 16%. The frequency and speed of actions in certain periods of care delivery made compliance measurement difficult and potentially unreliable. During several activities, taking time to apply alcohol gel or wash hands would have put the patients at significant risk. DISCUSSION: We concluded that hand hygiene compliance monitoring by direct observation was invalid and unreliable in this specialty. It is important that hand hygiene compliance is optimal in anaesthetics particularly before patient contact. Interventions which reduce environmental and patient contamination, such as cleaning the patient and environment, could ensure anaesthetists encounter fewer micro-organisms in this specialty.

Changing the paradigm: messages for hand hygiene education and audit from cluster analysis.

BACKGROUND: Hand hygiene is considered to be the foremost infection prevention measure. How healthcare workers accept and make sense of the hand hygiene message is likely to contribute to the success and sustainability of initiatives to improve performance, which is often poor. METHODS: A survey of nurses in critical care units in three National Health Service trusts in England was undertaken to explore opinions about hand hygiene, use of alcohol hand rubs, audit with performance feedback, and other key hand-hygiene-related issues. Data were analysed descriptively and subjected to cluster analysis. RESULTS: Three main clusters of opinion were visualized, each forming a significant group: positive attitudes, pragmatism and scepticism. A smaller cluster suggested possible guilt about ability to perform hand hygiene. CONCLUSION: Cluster analysis identified previously unsuspected constellations of beliefs about hand hygiene that offer a plausible explanation for behaviour. Healthcare workers might respond to education and audit differently according to these beliefs. Those holding predominantly positive opinions might comply with hand hygiene policy and perform well as infection prevention link nurses and champions. Those holding pragmatic attitudes are likely to respond favourably to the need for professional behaviour and need to protect themselves from infection. Greater persuasion may be needed to encourage those who are sceptical about the importance of hand hygiene to comply with guidelines. Interventions to increase compliance should be sufficiently broad in scope to tackle different beliefs. Alternatively, cluster analysis of hand hygiene beliefs could be used to identify the most effective educational and monitoring strategies for a particular clinical setting.

'Your experiences were your tools'. How personal experience of mental health problems informs mental health nursing practice.

WHAT IS KNOWN ON THE SUBJECT?: 'Expertise by experience' has become an increasingly valued element of service design and delivery by mental health service providers. The extent and influence of mental health professionals' personal experience of mental ill health on clinical practice has seldom been interrogated in depth. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: We investigate how mental health nurses' own personal experience of mental ill health informs their mental health nursing practice with particular reference to direct work with service users. Participants said that personal experience could impact on work in three positive ways: to develop their relationship with service users, to enhance their understanding of service users and as a motivation for potential mental health nurses to join the profession. This study moves the discussion of the state of mental health nurses' mental health further towards the recovery and well-being focus of contemporary mental health care, where 'expertise by experience' is highly valued. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: We must address the taboo of disclosure within clinical nursing practice and debate the extent to which personal and professional boundaries are negotiated during clinical encounters. ABSTRACT: Introduction 'Expertise by experience' is a highly valued element of service delivery in recovery-oriented mental health care, but is unacknowledged within the mental health nursing literature. Aim To explore the extent and influence of mental health professionals' personal experience of mental ill health on clinical practice. Method Twenty-seven mental health nurses with their own personal experience of mental ill health were interviewed about how their personal experience informed their mental health nursing practice, as part of a sequential mixed methods study. Results The influence of personal experience in nursing work was threefold: first, through overt disclosure; second, through the 'use of the self as a tool'; and third, through the formation of professional nursing identity. Discussion Mental health nurses' experience of mental illness was contextualized by other life experiences and by particular therapeutic relationships and clinical settings. In previous empirical studies, nurses have cited personal experience of mental illness as a motivator and an aspect of their identity. In this study, there was also an association between personal experience and enhanced nursing expertise. Implications for practice If drawing on personal experience is commonplace, then we must address the taboo of disclosure and debate the extent to which personal and professional boundaries are negotiated during clinical encounters.

Impact of observing hand hygiene in practice and research: a methodological reconsideration.

The purpose of hand hygiene is to break the chain of healthcare-associated infection. In many countries hand hygiene is regularly audited as part of quality assurance based on recommendations from the World Health Organization. Direct observation is the recommended audit method but is associated with disadvantages, including potential for being observed to alter usual behaviour. The Hawthorne effect in relation to hand hygiene is analogous with productivity improvement by increasing the frequency with which hand hygiene is undertaken. Unobtrusive and/or frequent observation to accustom staff to the presence of observers is considered an acceptable way of reducing the Hawthorne effect, but few publications have discussed how to implement these techniques or examine their effectiveness. There is evidence that awareness of being watched can disrupt the usual behaviour of individuals in complex and unpredictable ways other than simple productivity effect. In the presence of auditors, health workers might defer or avoid activities that require hand hygiene, but these issues are not addressed in guidelines for practice or research studies. This oversight has implications for the validity of hand hygiene audit findings. Measuring hand hygiene product use overcomes avoidance tactics. It is cheaper and generates data continuously to assess the compliance of all clinicians without disrupting patient care. Disadvantages are the risk of overestimating uptake through spillage, wastage, or use by visitors and non-clinical staff entering patient care areas. Electronic devices may overcome the Hawthorne and avoidance effects but are costly and are not widely used outside research studies.

The management of cytotoxic chemotherapy extravasation: a systematic review of the literature to evaluate the evidence underpinning contemporary practice.

Management of cytotoxic drug extravasation remains contentious, with differing views on the most effective management strategy. With the increasing drive to provide effective, evidence-based healthcare, while ensuring the patient experience of the treatment provided plays a significant part in the development of clinical practice guidelines, the purpose of this literature review was to both critically analyse the quality of evidence that underpins contemporary practice and to determine if the patient experience is taken into account. A literature search was undertaken sourcing publications from the 1960s to July 2014 identifying all studies detailing strategies aimed at preventing the need for surgical debridement and all studies evaluating extravasation management from the patient's perspective. No conclusive evidence was found to suggest one clinical strategy as more effective than the other. No studies were identified that evaluated outcome from the patient's perspective. It is therefore suggested that outcomes-based research should underpin contemporary extravasation management guidelines to determine what the final outcome or 'end result' is and how this impacts on the patient and that the current lack of research into the patient experience of extravasation management is an area that needs to be addressed.

Collecting the data but missing the point: validity of hand hygiene audit data.

BACKGROUND: Monitoring of hand hygiene compliance (HHC) by observation has been used in healthcare for more than a decade to provide assurance of infection control practice. The validity of this information is rarely tested. AIM: To examine the process and validity of collecting and reporting HHC data based on direct observation of compliance. METHODS: Five years of HHC data routinely collected in one large National Health Service hospital trust were examined. The data collection process was reviewed by survey and interview of the auditors. HHC data collected for other research purposes undertaken during this period were compared with the organizational data set. FINDINGS: After an initial increase, the reported HHC remained unchanged close to its intended target throughout this period. Examination of the data collection process revealed changes, including local interpretations of the data collection system, which invalidated the results. A minority of auditors had received formal training in observation and feedback of results. CONCLUSION: Whereas observation of HHC is the current gold standard, unless data collection definitions and methods are unambiguous, published, carefully supervised, and regularly monitored, variations may occur which affect the validity of the data. If the purpose of HHC monitoring is to improve practice and minimize transmission of infection, then a focus on progressively improving performance rather than on achieving a target may offer greater opportunities to achieve this.

Working practices and success of infection prevention and control teams: a scoping study.

Little research has been undertaken on how infection prevention and control (IPC) teams operate and how their effectiveness is assessed. This review aimed to explore how IPC teams embed IPC throughout hospitals, balance outbreak management with strategic aspects of IPC work (e.g. education), and how IPC team performance is measured. A scoping exercise was performed combining literature searches, evidence synthesis, and intelligence from expert advisers. Eleven publications were identified. One paper quantified how IPC nurses spend their time, two described daily activities of IPC teams, five described initiatives to embed IPC across organizations following legislation since 1999 in the UK or changes in the delivery of healthcare, and three explored the contribution of IPC intermediaries (link nurses and champions). Eight publications reported research findings. The others reported how IPC teams are embedding IPC practice in UK hospitals. In conclusion, there is scope for research to explore different models of IPC team-working and effectiveness, and cost-effectiveness. Other topics that need addressing are the willingness and ability of ward staff to assume increased responsibility for IPC and the effectiveness of intermediaries.

The efficacy of saline washout technique in the management of exfoliant and vesicant chemotherapy extravasation: a historical case series report.

This report presents the results from a historical case series of cytotoxic drug extravasations managed by saline washout; its purpose is to assess the efficacy of the procedure based on patient outcome. Eighty-nine patients were identified as having experienced a vesicant or exfoliant extravasation from incident reports filed over a 10-year period, from 1 April 2001 to 31 March 2011. Outcome was measured against the need for further surgical treatment being required. Of the 89 cases assessed for efficacy of saline washout one patient experienced a wound infection, which was treated effectively with oral antibiotics. There were no other complications reported and no patients required further treatment with surgical debridement. The majority of patients had no deferral of treatment as chemotherapy could be continued in their unaffected arm immediately following saline washout procedure. For patients where cannulation in their opposite arm for continuation of treatment was not advisable chemotherapy was delayed between 3 and 7 days. Hospitalisation as a result of the extravasation or subsequent treatment was not required in any of the 89 cases. Results indicate that saline washout technique is a safe and effective management strategy for the treatment of both vesicant and exfoliant chemotherapy extravasation.

Routine hand hygiene audit by direct observation: has nemesis arrived?

Infection prevention and control experts have expended valuable health service time developing and implementing tools to audit health workers' hand hygiene compliance by direct observation. Although described as the 'gold standard' approach to hand hygiene audit, this method is labour intensive and may be inaccurate unless performed by trained personnel who are regularly monitored to ensure quality control. New technological devices have been developed to generate 'real time' data, but the cost of installing them and using them during routine patient care has not been evaluated. Moreover, they do not provide as much information about the hand hygiene episode or the context in which hand hygiene has been performed as direct observation. Uptake of hand hygiene products offers an inexpensive alternative to direct observation. Although product uptake would not provide detailed information about the hand hygiene episode or local barriers to compliance, it could be used as a continuous monitoring tool. Regular inspection of the data by infection prevention and control teams and clinical staff would indicate when and where direct investigation of practice by direct observation and questioning of staff should be targeted by highly trained personnel to identify local problems and improve practice.

Patients and the public: knowledge, sources of information and perceptions about healthcare-associated infection.

Statutory bodies provide information about healthcare-associated infection (HCAI) in the UK. Information is also available on National Health Service trust websites. Opinion polls demonstrate that fear of developing HCAI, especially methicillin-resistant Staphylococcus aureus, is the single greatest concern of people contemplating healthcare. We undertook a literature review to determine lay knowledge of HCAI, sources of information and perceptions of the risks. Twenty-two studies met the inclusion criteria. Of these, nine explored knowledge and perceptions as the primary research aim. The remainder consisted of a heterogeneous assortment of works comparing the knowledge and perceptions of different groups, their experiences of being infected or colonised and/or isolated. In all accounts, lay people expressed anxiety about the risks and consequences of HCAI. The most frequently reported source was the media, which has been blamed for sensationalist and inaccurate accounts. Lay people do not appear to access credible sources of information, or, if they do access them, are unable to understand their messages. Organisations that provide patient-focused information about HCAI are generic in scope, so that obtaining specific information may take time and effort to locate. Research is necessary to explore the acceptability, comprehensibility and accessibility of lay sources of information about HCAI and to find ways of readjusting risk perceptions to realistic levels in order to provide sensible levels of reassurance to those about to undergo healthcare.
