Exploring the hand hygiene competence of student nurses: A case of flawed self assessment

Summary

Hand hygiene remains the single most effective measure to prevent hospital acquired infection and yet poor compliance is reported repeatedly. Nurses represent the largest labour group and perform the greatest amount of direct patient care in the contemporary National Health Service. They receive their initial hand hygiene training in the pre-registration curriculum within a competence framework based on knowledge, skills and attitudes. The pre-eminent training method is one that delivers behavioural competence, making the tacit assumption that compliance will follow. In this study a mixed methods approach demonstrated that students overestimated their knowledge and skills, found it difficult to give an objective account of their performance, and reported an improbable level of compliance. The reasons why people can be self serving in their judgements may be due to information processing errors, exacerbated by the model of education and training. Flawed self assessments may present major barriers to improved performance if students view their compliance as better than it actually is. Conceptualising hand hygiene as a taxonomy of learning and introducing the cognitive strategies of reflection and self assessment would better enable students to problem solve, seek out new information, draw on past experience and gain greater and deeper understanding of the complex topic of hand hygiene behaviour.

Introduction and background

Hand hygiene remains the single most effective measure to prevent Hospital Acquired Infection (Hass and Larson, 2007, Department of Health, 2003, Pratt et al., 2001). It has spawned a plethora of research (Whitby et al., 2006, Creedon, 2005, McGukin, 2004, Bischoff et al., 2000) and has been referred to as both a simple mechanical task (Paotong et al., 2003, Fell, 2000) and a complex behavioural phenomenon (Pittet, 2004). Its importance does not appear to be sufficiently recognised by health

Design

A methodological triangulation (Shih, 1998, Dootson, 1995) which combined two data collection procedures, a questionnaire and interview was the chosen method for this study. Methodological triangulation is ideally suited when studying complex concepts, like attitude and behaviour that may contain many dimensions (Begley, 1996). Advocates of mixed methods argue that all research approaches are designed to understand and explain behaviour and events, their components, antecedents, corollaries,

Quantitative

All scores with the exception of one were subject to a seven point likert scale, with seven being the highest possible score. The mode was used to highlight the most common answer (Table 1). Although crude, the results appear to confirm the theory that health care workers do not make objective self assessments in relation to their hand hygiene compliance (Jenner et al., 2006). A mode of 7 in relation to personal compliance is discordant with compliance rates reported from observational studies (

Discussion

In the quantitative phase of the study respondents reported a positive attitude and high self evaluation of their hand hygiene behaviour. Although no attempt was made to observe their behaviour this is consistent with the notions of high self assessment and over reporting that are well established in the literature (O’Boyle et al., 2001, Alexander and Sirotnak, 1997, Larson et al., 1997, Tibballs, 1996 Alvaran et al., 1994, Henry et al., 1994). When researchers correlate self assessment of

Conclusion

The word competence is used extensively in nursing education and is gaining international recognition as a means of developing the clinical skills that are a critical component of any undergraduate nursing programme. Hand hygiene is considered a core skill, that can have an enormous impact on the morbidity and mortality associated with hospital acquired infection. Although presented as a simple, mechanical procedure, compliance associated with hand hygiene is in fact complex and incorporates
