The student is key: A realist review of educational interventions to develop analytical and non-analytical clinical reasoning ability.

OBJECTIVES

Clinical reasoning refers to the cognitive processes used by individuals as they formulate a diagnosis or treatment plan. Clinical reasoning is dependent on formal and experiential knowledge. Developing the ability to acquire and recall knowledge effectively for both analytical and non-analytical cognitive processing has patient safety implications. This realist review examines the way educational interventions develop analytical and non-analytical reasoning ability in undergraduate education. A realist review is theory-driven, seeking not only to identify if an intervention works, but also understand the reasons why, for whom, and in what circumstances. The aim of this study is to develop understanding about the way educational interventions develop effective analytical and non-analytical clinical reasoning ability, when they do, for whom and in what circumstances.

METHODS

Literature from a scoping search, combined with expert opinion and researcher experience was synthesised to generate an initial programme theory (IPT). Four databases were searched and articles relevant to the developing theory were selected as appropriate. Factors affecting educational outcomes at the individual student, teacher and wider organisational levels were investigated in order to further refine the IPT.

RESULTS

A total of 28 papers contributed to the overall programme theory. The review predominantly identified evidence of mechanisms for interventions at the individual student level. Key student level factors influencing the effectiveness of interventions included an individual's self-confidence, self-efficacy and pre-existing level of knowledge. These contexts influenced a variety of educational interventions, impacting both positively and negatively on educational outcomes.

CONCLUSIONS

Development of analytical and non-analytical clinical reasoning ability requires activities that enhance knowledge acquisition and recall alongside the accumulation of clinical experience and opportunities to practise reasoning in real or simulated clinical environments. However, factors such as pre-existing knowledge and self-confidence influence their effectiveness, especially amongst individuals with 'low knowledge.' Promoting non-analytical reasoning once novices acquire more clinical knowledge is important for the development of clinical reasoning in undergraduate education.
