Abstract

Objectives To assess whether consultants do what they say they do in reaching decisions with their patients.

Design Cross-sectional analysis of hospital outpatient encounters, comparing consultants’ self-reported usual decision-making style to their actual observed decision-making behaviour in video-recorded encounters.

Setting Large secondary care teaching hospital in the Netherlands.

Participants 41 consultants from 18 disciplines and 781 patients.

Primary and secondary outcome measure With the Control Preference Scale, the self-reported usual decision-making style was assessed (paternalistic, informative or shared decision making). Two independent raters assessed decision-making behaviour for each decision using the Observing Patient Involvement (OPTION)5 instrument ranging from 0 (no shared decision making (SDM)) to 100 (optimal SDM).

Results Consultants reported their usual decision-making style as informative (n=11), shared (n=16) and paternalistic (n=14). Overall, patient involvement was low, with mean (SD) OPTION5 scores of 16.8 (17.1). In an unadjusted multilevel analysis, the reported usual decision-making style was not related to the OPTION5 score (p>0.156). After adjusting for patient, consultant and consultation characteristics, higher OPTION5 scores were only significantly related to the category of decisions (treatment vs the other categories) and to longer consultation duration (p<0.001).

Conclusions The limited patient involvement that we observed was not associated with the consultants’ self-reported usual decision-making style. Consultants appear to be unconsciously incompetent in shared decision making. This can hinder the transfer of this crucial communication skill to students and junior doctors.

Strengths and limitations of this study

  • The main strength of our study was that we combined direct observations of consultants’ shared decision making (SDM) behaviour with their self-reported usual decision-making style in a large sample of clinical decisions across 18 different disciplines.

  • The results of this study can be used to optimise healthcare professionals’ SDM training and support further implementation of this crucial skill.

  • The consultants were aware of being recorded, which may have affected their SDM behaviour.

  • The cross-sectional design of this study precludes causal inference of the associations we observed.

  • The study was performed in a single, large hospital in the Netherlands, which may have limited the generalisability of our results to other settings and countries.

Introduction

In Western societies, shared decision making (SDM) is increasingly championed by patients, clinician organisations and policy-makers as the preferred model for making patient-centred healthcare decisions1–5 and achieving value based healthcare.6 The implementation of SDM in clinical practice, however, remains suboptimal.7–9 Clinician-reported barriers to applying SDM include time constraints and the perceived incapability of patients to participate in decision making.10 Advancing the implementation of SDM is also hindered by clinicians’ perception that they already practise SDM.10 11 Several qualitative and quantitative studies in which clinicians were asked to report their usual decision-making style showed that clinicians feel that they already involve patients in decision making about their care.10–12 This finding contradicts the results of a systematic review of 33 studies, which showed that the degree of patient involvement in actual medical decision making is low.7 This raises the question of how accurate clinicians’ judgments of their own decision-making behaviour are. This is important for several reasons. First, clinicians are role models for medical students and residents. They need to be aware of their role in the decision-making process and be competent in SDM to be able to demonstrate and teach this crucial communication skill to students and residents. Second, unreliable clinician self-reports of decision-making behaviours may undermine the accuracy and reliability of SDM research that is based on self-reported data. Third, the design of SDM training programmes partly depends on participants’ awareness of their SDM competency. Skills training may be particularly effective if participants are aware of their incompetence, become motivated to change their behaviour and are willing to repeatedly reflect on their behaviour when applying the newly acquired skill to become better at it.13 To help advance the implementation of SDM and create awareness around personal biases, we sought to uncover/investigate a potential gap between clinicians’ perceived and actual decision-making behaviour. Therefore, we studied whether consultants do what they say they do in reaching decisions with their patients. We compared their self-reported usual decision-making style with their actual decision-making behaviour in hospital-based consultations.

Methods

We analysed videorecorded outpatient encounters between medical consultants and their patients in Isala Hospital, a large general teaching hospital serving a population of approximately 600 000 people in a mixed urban-rural area in the Netherlands. We used a single camera with a fixed focus on the consultant only. The consultations were recorded between November 2018 and April 2019.

Participants and recruitment procedure

All participating medical consultants were recruited among participants of our previous cross-sectional survey.11 The consultants were invited via email by the main researcher (EMD) to participate in this observational study of video-taped encounters. There was no working relationship or power relation between the researchers and the consultants who were invited and we made it clear in the information for participants that participation was voluntary. Participants were not recruited based on specific characteristics.

We aimed to include a minimum of 30 consultants and 10 encounters per consultant, which is a requirement for multilevel analysis of nested observations at the level of the healthcare professional.14 We enrolled consecutive outpatients of the participating consultants. To protect the patients’ anonymity, we only captured them on audio. All participants, consultants and patients, provided written informed consent.

Coding

Usual style of decision making

In our previous study, we obtained the participating consultants’ perceptions of their usual style of medical decision making with the modified Control Preference Scale (CPS). Their responses to the CPS questions, were classified as paternalistic (clinician decides), informative (patient decides) or SDM.11

Decision types

Two researchers (EMD and R Hartog) distinguished the main decision from all other decisions in a consultation (decision type). The main decision was defined as the decision that was directly related to the patient’s chief complaint as expressed during the consultation. Differences in decision type classification between researchers were resolved by discussion with an independend third researcher (PLPB) and consensus. Then we categorised the main decisions into three decision types: diagnostic (gathering additional information), treatment and follow-up. We chose the consultants’ main decisions for our analyses because we assumed that they had the major decisions in mind when they reported their usual decision-making behaviour.

Observed patient involvement

Several instruments are available to asses SDM in medical consultations. The Observing Patient Involvement (OPTION) scale, developed by Elwyn et al assesses the extent to which consultants involve patients in the decision-making process (for the items see online supplemental table A).15 This instrument has been used frequently in SDM research. Because it focuses on clinician behaviour, it appeared suitable for our research question. The OPTION5 is the validated concise version of the OPTION instrument15 and is considered to be more efficient with lower cognitive burden for raters than the original 12-item instrument16 Following the OPTION5 manual, each item was scored on a Likert-scale ranging from 0 (no effort) to 4 (exemplary effort). Following recommendation of the OPTION5 scoring manual, these items were rescaled by a factor 5 (resulting in items scores ranging from 0 to 20, and total scores ranging from 0 to 100.17 Two trained researchers (EMD, a medical doctor and RH, a linguistics master student) independently scored the first 29 videotaped encounters using the OPTION5. Then they compared and discussed scoring differences until consensus was reached. In the next step, they independently scored 179 subsequent encounters to assess inter-observer reliability. After we found good inter-rater agreement (intraclass correlation coefficient=0.938), the remaining consultations were scored by one researcher.

Statistical analysis

The OPTION5 instrument is ordinal by design, which implies that nonparametric statistical analyses are required. In most studies, however, OPTION5 scores have been analysed as a continuous variable using parametric statistical techniques.14 Therefore, we assessed the differences in OPTION5 scores between groups using both nonparametric and parametric analyses. Since these analyses showed comparable results and to facilitate comparison with other studies, further data analysis was carried out using parametric tests only. Given the nested nature of the data, with multiple observations for each participating consultant, we selected multilevel modelling as the most appropriate method for analysis. We built random intercept models, with the self-reported usual decision-making style as the predictor and the OPTION5 scores of the main decisions as outcomes. We adjusted for potential confounding variables such as decision type, consultants’ and patients’ age and gender, consultation duration, consultation type (new patient, or follow-up consultation) and discipline (medical, or surgical, as described earlier.18 For all analyses, the alpha level was set at 0.05. Univariate analyses were performed using SPSS (V.26). Multilevel analyses were performed using MLWIN (V.3.04).

Patient and public involvement

Neither study participants nor the public were involved in the study design or data analysis.

Results

Forty-one consultants (28 males, 68%) participated in our study with a mean age (SD) of 47.9 (8.0) years, from 18 specialties (23 from medical and 18 from surgical discipline, see online supplemental table B). Fourteen participants had reported paternalistic decision making, 16 SDM and 11 informative decision making as their usual decision-making style in our previous study.11 In total, 781 patients (15–24 per consultant) participated in our study. After excluding 36 consultations from the analysis because of insufficient audio quality and 18 preoperative anaesthesiology consultations in which no decisions were made, we analysed 1564 decisions from 727 consultations. The median (range) number of decisions per consultation was two (1-6). Of the 727 patients, 347 were male (48%), and the mean (SD) age was 48.6 (24.6) years. There were 239 consultations with new patients (33%) and 488 follow-up consultations (67%). The mean (SD) duration of the consultations was 15 (9) minutes, with a minimum of 1 and maximum of 50 min.

OPTION5 scores

Scores on the 5 items of the OPTION5 (see online supplemental table A) were expressed on a scale ranging from 0 (no SDM) to 20 (optimal SDM) per item. The highest scores were found for item 1 (the consultant draws attention to, or confirms, that alternate management options exist, recognising the need for a decision; mean (SD) score 5.1 (4.0) (on a 0 to 20 scale) and item 3 (the consultant gives information, or checks understanding, about the reasonable options that are available for the patient, including the choice of ‘no action’; mean (SD) score 4.7 (5.0) on a 0 to 20 scale. Intermediate scores were found for item 4 (the consultant elicits the patient’s preferred option(s); mean (SD) scores 3.3 (4.4)) and item 5 (the consultant makes an effort to integrate the patient’s elicited preferences in the decision-making process; mean (SD) score 2.9 (4.1), each om a 0–20 scale. The lowest scores were found for item 2 (the consultant supports the patient to become informed or deliberate about the options; mean (SD) score of 0.9 (2.4) on a 0 to 20 scale.

The mean (SD) total OPTION5 score for the main decision was 16.8 (17.1) on a scale ranging from 0 (no SDM) to 100 (optimal SDM). The OPTION5 scores varied both within and between consultants, see figures 1 and 2). Univariate analysis showed that the mean (SD) OPTION5 scores on consultations of consultants who reported SDM (18.9 (17.3) on a 0–100 scale). as their usual decision-making style were slightly higher than the mean scores on consultations of consultants who reported an informative (15.6 (17.9)) or paternalistic style of decision making (15.0 (15.8), p=0.017). In an unadjusted multilevel analysis, the reported usual decision-making style was not related to the OPTION5 score (p>0.156). After adjusting for patient, consultant and consultation characteristics, higher OPTION5 scores were only significantly related to the category of decisions (treatment vs the other categories) and longer consultation duration. Table 1 presents the model that best fitted the data. The full model including all patient and consultant characteristics is presented in online supplemental table C. This full model showed similar results but provided a poorer overall fit to the data compared with the model presented in table 1.

Discussion

Using self-reported statements of usual decision-making style and an independent assessment of consultants’ actual decision-making behaviour in video-recorded consultations we sought to investigate a potential gap between consultants’ perceived and actual decision-making behaviours in consultations. In a multilevel analysis of our data, the observed degree of patient involvement in video-recorded consultations was not associated with the consultants’ self-reported usual decision-making style. In other words, the medical consultants in this study did not do what they said they did in reaching decisions with their patients. Following four stages of competence model that is commonly used in the training of clinical skills,19 these consultants can be described as ‘unconsciously incompetent’ in SDM. This is important because they are the role models for medical students and junior doctors. To be able to demonstrate and teach this crucial communication skill to medical learnes, consultants need to be aware of their role in the decision-making process and be competent in SDM. To be receptive to SDM training, consultants first need to be consciously aware of their limited skills in involving patients in treatment decisions (‘conscious incompetence’ in Broadwell’s and Maslow’s model). In our study, only the consultants who had reported paternalistic decision making as their usual style appeared to be ‘consciously incompetent’ in the terminology of this model. In addition, the discrepancy between consultants’ self-reported usual decision-making style and the observed patient involvement in their consultations undermines the validity of SDM research using self-reported measures.

Comparison with other studies

Patient involvement was limited, with mean OPTION5 scores below the proposed cut-off value of 25,7 which is comparable to several other studies.9 20 We found considerable differences in OPTION5 scores between consultations of each individual consultant (figure 2), suggesting that individual consultants’ patient involvement behaviour is variable. Further research is needed to explore the reasons for this variation, which could be related to physician, patient or organisational factors. Limited patient involvement was associated with decision type (treatment vs diagnostic or follow-up decisions) and longer consultation duration (table 1). The cross-sectional nature of our study did not allow us to identify what the cause is and what the effect. (Lack of) time is often reported as a key barrier to the application of SDM in clinical practice.10 21–23 The literature on the actual impact of applying SDM on consultation duration is too scant to allow a clear estimation of the effects.23 24 Patient and consultant characteristics such as age and gender were not related to the OPTION5 scores in the multilevel model (table 1 and online supplemental table C). This is in accordance with a systematic review of 33 studies on OPTION5 scores.7

The previous literature comparing clinicians’ self-reported and actual decision-making style in medical consultations also showed that clinicians tend to overestimate the extent to which they apply SDM.20 25 These studies analysed simple decisions in primary care such as refills and routine testing20 or were performed in specific breast cancer or renal failure clinics in which the staff had been extensively trained in the application of SDM.25

Strengths and limitations

The main strength of our study was that we combined direct observations of consultants’ SDM behaviour in a large sample of clinical decisions across 18 different disciplines with their self-reported usual decision-making style. We acknowledge the following limitations of our study. First, the consultants were aware that their behaviour in the decision-making process was recorded and assessed, which may have prompted them to show more SDM behaviour than they otherwise would. However, so far, there is no indication that videotaping consultations has an effect on clinicians’ behaviour.26 27 Second, the cross-sectional design of this study precludes causal inference of the associations we observed. Third, it is possible that we only scored part of the decision-making process if decisions were distributed over more than one consultation. Our approach to analysis is comparable to that in earlier studies,7 so this does not affect comparison of our results to those found in the literature. Fourth, our study was performed in a single, large hospital in the Netherlands, which may have limited the generalisability of our results to other settings and countries. Finally, like in earlier studies using the OPTION5 instrument, our study focused on clinician behaviour and not on not on patients’ experiences. Given the scant literature on the topic,20 28 29 more studies are needed to assess how patients experience the decision-making process in medical consultations

Conclusion and practical implications

Our study shows that medical consultants are unable to assess their own decision making-behaviour in medical encounters. This undermines the validity of SDM research using self-reported measures. Even more importantly, the consultants’ unconscious incompetence in SDM hampers transfer of this crucial communication skill to students and junior doctors. In addition, consultants’ motivation to participate in effective SDM training programs30–32 is likely to increase when they are consciously aware of their incompetence in practising SDM. Our results therefore support the use of videorecorded patient consultations to help consultants regularly review, reflect on and increase their awareness of their own decision-making behaviours. This, in turn, may promote consultants’ willingness to participate in SDM training programmes, which is necessary for further implementation of SDM in clinical practice.
