Tracy Flenady, Trudy Dwyer, and Judith Applegarth, Central Queensland University, Australia Abstract The aim of this classic grounded theory study was to unearth the main concern of emergency department (ED) registered nurses (RN) when they perform respiratory rate observations to generate a substantive theory that explicates how the identified problem is resolved. Analysis of data collected from 79 registered nurses revealed that health sector forced compliance in recording observations meant that ED RNs are more than likely to record a respiratory rate without actually counting respirations. This erroneous behaviour provokes varying degrees of emotional discomfort as the nurses’ actions are often incongruent with their professional values and beliefs. The theory Rationalising Transgression explains how nurses continually resolve this issue by compensating, minimalizing, or trivialising to titrate the level of emotional discomfort associated with erroneous behaviour, consequently facilitating the rationalisation of transgression. Keywords: nursing, wasting time, trivialising, cutting corners, emotional discomfort, social norms. Background It is internationally acknowledged that inconsistent monitoring of vital sign observations and lack of understanding regarding the significance of physiological changes patients experience are two contributing factors of undetected clinical deterioration (Australian Commission on Safety and Quality in Health Care [ACSQHC], 2012; National Institute for Clinical Excellence, 2007; National Patient Safety Agency, 2007). Vital sign observations provide health care clinicians with valuable information regarding each patient’s clinical acuity throughout all stages of their emergency department stay. Many hospitals now employ observation charting systems that require nurses to measure and record scores for each vital sign observed, with the combined value of scores referred to as an early warning score (Day & Oxton, 2014; Prytherch, Smith, Schmidt, Featherstone, Stewart, Knight, & Higgins, 2006). The total score from each round of observations is a reliable predictor of clinical deterioration; when the score reaches a certain threshold, a predetermined response is triggered (Ludikhuize, Smorenburg, de Rooij, & de Jonge, 2012; Silcock, Corfield, Gowens, & Rooney, 2015). There are many studies whose authors reported the efficacy of these early warning scores in regards to the timely identification of clinical deterioration of patients in an emergency department setting (Hogan, 2006; Hosking, Considine, & Sands, 2014; Lam, Mak, Siu, Lam, Cheung, & Rainer Lam, 2006; So, Ong, Wong, Chung, & Graham, 2015). The respiratory rate, one of the vital signs that contribute to the early warning score, is significant in that abnormal respiratory rates alone are widely reported as accurate indicators of clinical deterioration (Considine, 2004; Considine, Charlesworth, & Currey, 2014; Hosking et al., 2014; Jonsson, Jonsdottir, Möller, & Baldursdottir, 2011; Ljunggren, Castrén, Nordberg, & Kurland, 2016; Parkes, 2011). Abnormal respiratory rates herald potentially life-threatening conditions and provide health care clinicians with the opportunity to respond expediently to these episodes of clinical decline. Timely recognition and response to clinical deterioration have the potential to prevent high acuity unit admissions, reduce hospital admission length of stay and significantly improve overall mortality rates (Ljunggren et al., 2016; McBride, Knight, Piper, & Smith, 2005). Accordingly, to achieve optimal patient outcomes, it is integral that respiratory rate observations are collected regularly, obtained correctly, and recorded accurately for every patient. Despite this acknowledged importance of the respiratory rate observation, Ansell, Meyer, and Shona (2014), Cooper, Cant, and Sparkes (2014), Cretikos et al., (2008), Hosking et al., (2014), Odell et al., (2007) and Parkes (2011) revealed this vital sign is often absent or erroneously recorded on emergency department observation charts. While emergent literature confirms this practice occurs, what is not known is why it occurs. One of the...
