Abstract

Objective

To investigate changes of different domains of breaking bad news (bbn) competences after a teaching module for medical students, and to collage the results generated by different approaches of evaluation.

Methods

Rating of medical student–SP interactions by means of a global rating scale and a detailed checklist used by SPs and independent raters.

Results

Students improved their breaking bad news competency. However, the changes vary between the different domains of bbn competency. In addition, results generated by different evaluation instruments differ.

Conclusion

This study serves as a stimulus for further research on the training of specific elements of bbn and different approaches of evaluating bbn competency.

Practice implications

In light of the different facets of bbn competency, it is important to set priorities regarding the teaching aims and to provide a consistent approach.

Introduction

Breaking bad news is a frequent and at the same time challenging task for physicians in most clinical specialities [1], [2], [3]. Various study groups have published guidance on the professional handling of this difficult communication situation over the last few years [4], [5] and teaching courses on breaking bad news have been implemented as part of the undergraduate and postgraduate curricula in North America and several European countries [3], [6], [7]. There is evidence that small group teaching interventions which incorporate experiential methods (i.e. role play, standardised patients) and principles of a learner-centred approach improve course participants’ perceived self-efficacy [8], [9] and observable communication skills [10], [11], [12].

The methods which have been used to measure breaking bad news competency differ with respect to the type of the instruments (e.g. detailed checklist, global rating scales) and the raters (e.g. standardised patients, independent raters) [3], [13]. The different possible approaches towards the measurement of communication skills have been discussed not only with respect to feasibility and reliability of assessment but also regarding possible implications for the validity of results gained by the use of different instruments and/or raters [14], [15]. A more detailed analysis of empirical studies on the evaluation of breaking bad news interventions further indicates that there is variation regarding the different communication competences relevant for breaking bad news which have been shown to improve following a teaching intervention [12], [16], [17], [18], [19], [20].

There is a scarcity of empirical research in which different approaches to assess breaking bad news competences have been systematically compared [21], [22]. On the basis of the methodical discussions about differing approaches towards the assessment of breaking bad news competency and for the purpose of the identification of an appropriate and feasible evaluation strategy with respect to our own teaching courses, an evaluation study was designed in which different types of instruments (detailed checklist and global rating scale) were used by the same raters, and different raters (independent raters and standardised patients) used the same measurement instrument (global rating scale) to assess the possible effects of a breaking bad news intervention (see Fig. 1a).

The aims of this research were as follows:

  • 1.

    To investigate possible changes regarding the different communication competencies of medical students relevant for breaking bad news before and after a teaching module on breaking bad news.

  • 2.

    To compare the results generated by different approaches to measure communication skills.

The results of this study will be discussed with a focus on their implications for an appropriate and consistent design of the teaching and the evaluation of breaking bad news competency.

Teaching course, participants and study protocol

The teaching course on breaking bad news evaluated in this study is one of several special study modules in the field of medical humanities which are offered to third-year medical students at the Friedrich-Alexander-University Erlangen-Nuremberg. At the time of this study there was no other communication skill training using simulated patients as part of the medical curriculum. On this basis the teaching of breaking bad news in this course also covered some basic aspects of communication

Results

Thirty-seven medical students (27 female, 10 male) took part in the teaching sessions. All 74 videotaped medical interactions of SPs and third-year medical students were included for analysis. Both groups taking part in the two courses of similar content were comparable regarding the characteristics of participants and their performance before and after the course.

Discussion

This paper presents data of an evaluation study in which the possible effects of a teaching intervention for medical students on breaking bad news were explored by means of different measurement instruments as well as from different rating perspectives (i.e. independent raters vs. standardised patients). Even with a small sample, a comparably weak power statistical analysis showed a significantly improved overall breaking bad news competency following the teaching course. This finding is

      To assess how successfully the participants accomplished this BBN task, their performances were video-recorded and independently rated by three outcome assessors (Master’s-level psychology students). Assessors used the five-point SPIKES scale [26] and the ‘global Breaking Bad News Assessment Scale’ (glBAS) [31]. Each participant’s final SPIKES and glBAS scores were calculated as grand means based on the assessors’ ratings.

      The SPIKES protocol,6 developed by a group of American and Canadian medical oncologists, provides methods and strategies for disclosing a cancer diagnosis; these strategies help constructively respond to what happens during the revelation of bad news, according to patients’ reactions (Table III). Its recommendations have been found to positively affect patient outcomes47,52,53 and have been used as a major reference for patient–clinician communication guidelines in the United States, Chile, Germany, Brazil, and a number of other countries.8,54-56 The SPIKES proposal involves gathering information from patients, which helps identify their knowledge and perceptions about their conditions and the expectations and their willingness to receive bad news.56
