Using judgement analysis to identify dietitians' referral prioritisation for assessment in adult acute services

Power, autonomy and interprofessional practice in dietitian clinical decision making: An interpretive study in acute hospitals

Dietitians learn clinical decision making (CDM) predominantly as an autonomous cognitive process that considers the needs and preferences of the patient. Although interprofessional education is increasing in tertiary dietetic programmes, a paucity of research exists that explores the nature of how practising dietitians make decisions, independent or otherwise. This qualitative interpretative study explored the nature of experienced dietitian CDM in the acute care setting. Philosophical hermeneutic principles guided text construction and interpretation via in-depth, semi-structured interviews with practising dietitians with at least 3 years of experience. A reference focus group commented on the emerging findings, increasing the rigour of the research. Ten dietitians participated in the interviews and there were five dietitians in the reference focus group. CDM was found to be a highly social phenomenon with varying degrees of autonomy involving complex power relations with various other health professionals, in particular, medical practitioners. Dietitians respond to existing power relations in key ways, including building and maintaining relationships, advocating on behalf of the patient and negotiating decisions with other healthcare staff when in pursuit of improved health and nutrition related outcomes for patients. Strategic interprofessional communication skills are foundational to effective patient care and advancing the role of the dietitian. Power and autonomy in dietitian CDM are important concepts that could inform interprofessional education when seeking to promote both effective dietetic and interprofessional practice.

The role of dietitian clinical judgement in the nutrition care process within the acute care setting: a qualitative study

BACKGROUND

Dietitian clinical decision making in the acute care setting likely incorporates a practitioner's clinical judgement to effectively support patient care. The term 'dietitian clinical judgement' is well used in clinical practice, yet is poorly defined and often used interchangeably with other concepts. The aim of this research was to describe the nature of dietitians' clinical judgement in the acute care setting.

METHODS

A qualitative design within the interpretative paradigm was used guided by principles of philosophical hermeneutics. Dietitians with at least 3 years experience were invited to participate in two 60-min in-depth semi-structured interviews which were recorded, transcribed and interpreted using hermeneutic principles. A reference group was used to increase rigour and further interpretation of the findings.

RESULTS

Ten dietitians participated in the interviews and five of these same participants in the reference focus group. The findings revealed clinical judgement to be a sophisticated practitioner dependent meta-reasoning process that helps the dietitian manage complexity, guide interpersonal interactions and individualise patient care. It is characterised by tacit and efficient use of various reasoning strategies reliant on the dietitian's clinical experience, used to synthesise and weigh up various types of information and knowledge with respect to delivering context-relevant care.

CONCLUSIONS

Dietitian clinical judgement is a necessary part of clinical decision making that extends beyond logical or critical thinking. It facilitates a person-centredness to patient care and professional relationships that are key dimensions to dietitian clinical decision making. These findings provide training and professional development insights to managers, educators and supervisors.

Enhanced referral prioritisation for acute adult dietetic services: A randomised control trial to test a web-based decision training tool

BACKGROUND & AIMS

Dietitians in acute adult services need to prioritise dietetic referrals in order to manage their daily workload and ensure effective treatment of patients. Newly qualified dietitians do not usually receive specific training on prioritisation and could be helped with an evidence-based, effective, decision-training tool that is based on the practice of experienced dietitians. We developed an internationally available web-based decision-training tool designed to improve novice dietitians' ability to make dietetic prioritisation decisions. The training tool comprised of a pre-training task, a post-training task and training materials. The aim of this study was to test the effectiveness of the training tool on novices' ability for dietetic prioritisation.

METHODS

Pre-registration dietitians and recent graduates (one-year) from across the UK were invited to participate in this randomised controlled trial (RCT). Each participant made prioritisation decisions on a set of dietetic referral scenarios: 53 scenarios at pre-training and 27 at post-training. After pre-training the intervention group was presented with the training materials, whereas the control group was told to carry on with the post-training task. Participants did not know which group they had been randomly allocated to. We calculated i) level of agreement between decisions made by each novice and experts' consensus using Pearson correlation, intra-class correlation (ICC(2,1)); ii) intra-rater consistency using ICC(1,1) and iii) intra-group consistency using ICC (2,1). We compared group means at pre-training and post-training; estimated effect size using the degree of change from pre- to post-training, and 2-factor mixed ANOVA to assess overall effect of the training across the groups and time-points.

RESULTS

151 participants (69 in control and 82 in intervention) completed the trial. The groups did not differ in demographic characteristics. Both Pearson and ICC(2,1) correlations increased with training intervention; a moderate effect of training was found for both metrics, d = 0.69 (r = 0.32) for the former and d = 0.54 (r = 0.26) for the latter. Intra-rater consistency improved with training but with a small effect size, d = 0.32 (r = 0.16). The intra-group consistency also improved with training: ICC = 0.48 pre-training to 0.61 post-training.

CONCLUSIONS

The training tool was found to be effective in improving the novice dietitian's ability to prioritise referrals in the acute adult setting. The training tool is freely available at www.dietitianreferral.org for use by all student or early career dietitians internationally.
