Background

Medical faculty's teaching performance is often measured using residents' feedback, collected by questionnaires. Researchers extensively studied the psychometric qualities of resulting ratings. However, these studies rarely consider the number of response categories and its consequences for residents' ratings of faculty's teaching performance. We compared the variability of residents' ratings measured by five- and seven-point response scales.

Methods

This retrospective study used teaching performance data from Dutch anaesthesiology residency training programs. Questionnaires with five- and seven-point response scales from the extensively studied System for Evaluation of Teaching Qualities (SETQ) collected the ratings. We inspected ratings' variability by comparing standard deviations, interquartile ranges, and frequency (percentage) distributions. Relevant statistical tests were used to test differences in frequency distributions and teaching performance scores.

Results

We examined 3379 residents' ratings and 480 aggregated faculty scores. Residents used the additional response categories provided by the seven-point scale - especially those differentiating between positive performances. Residents' ratings and aggregated faculty scores showed a more even distribution on the seven-point scale compared to the five-point scale. Also, the seven-point scale showed a smaller ceiling effect. After rescaling, the mean scores and (most) standard deviations of ratings from both scales were comparable.

Conclusions

Ratings from the seven-point scale were more evenly distributed and could potentially yield more nuanced, specific and user-friendly feedback. Still, both scales measured (almost) similar teaching performance outcomes. In teaching performance practice, residents and faculty members should discuss whether response scales fit their preferences and goals.

Background

In fledgling areas of research, evidence supporting causal assumptions is often scarce due to the small number of empirical studies conducted. In many studies it remains unclear what impact explicit and implicit causal assumptions have on the research findings; only the primary assumptions of the researchers are often presented. This is particularly true for research on the effect of faculty's teaching performance on their role modeling. Therefore, there is a need for robust frameworks and methods for transparent formal presentation of the underlying causal assumptions used in assessing the causal effects of teaching performance on role modeling. This study explores the effects of different (plausible) causal assumptions on research outcomes.

Methods

This study revisits a previously published study about the influence of faculty's teaching performance on their role modeling (as teacher-supervisor, physician and person). We drew eight directed acyclic graphs (DAGs) to visually represent different plausible causal relationships between the variables under study. These DAGs were subsequently translated into corresponding statistical models, and regression analyses were performed to estimate the associations between teaching performance and role modeling.

Results

The different causal models were compatible with major differences in the magnitude of the relationship between faculty's teaching performance and their role modeling. Odds ratios for the associations between teaching performance and the three role model types ranged from 31.1 to 73.6 for the teacher-supervisor role, from 3.7 to 15.5 for the physician role, and from 2.8 to 13.8 for the person role.

Conclusions

Different sets of assumptions about causal relationships in role modeling research can be visually depicted using DAGs, which are then used to guide both statistical analysis and interpretation of results. Since study conclusions can be sensitive to different causal assumptions, results should be interpreted in the light of causal assumptions made in each study.

Objective

Previous studies identified different typologies of role models (as teacher/supervisor, physician and person) and explored which of faculty's characteristics could distinguish good role models. The aim of this study was to explore how and to which extent clinical faculty's teaching performance influences residents' evaluations of faculty's different role modelling statuses, especially across different specialties.

Methods

In a prospective multicenter multispecialty study of faculty's teaching performance, we used web-based questionnaires to gather empirical data from residents. The main outcome measures were the different typologies of role modelling. The predictors were faculty's overall teaching performance and faculty's teaching performance on specific domains of teaching. The data were analyzed using multilevel regression equations.

Results

In total 219 (69% response rate) residents filled out 2111 questionnaires about 423 (96% response rate) faculty. Faculty's overall teaching performance influenced all role model typologies (OR: from 8.0 to 166.2). For the specific domains of teaching, overall, all three role model typologies were strongly associated with "professional attitude towards residents" (OR: 3.28 for teacher/supervisor, 2.72 for physician and 7.20 for the person role). Further, the teacher/supervisor role was strongly associated with "feedback" and "learning climate" (OR: 3.23 and 2.70). However, the associations of the specific domains of teaching with faculty's role modelling varied widely across specialties.

Conclusion

This study suggests that faculty can substantially enhance their role modelling by improving their teaching performance. The amount of influence that the specific domains of teaching have on role modelling differs across specialties.

Background

It is widely held that the occupational well-being of physicians may affect the quality of their patient care. Yet, there is still no comprehensive synthesis of the evidence on this connection.

Purpose

This systematic review studied the effect of physicians' occupational well-being on the quality of patient care.

Methods

We systematically searched PubMed, Embase, and PsychINFO from inception until August 2014. Two authors independently reviewed the studies. Empirical studies that explored the association between physicians' occupational well-being and patient care quality were considered eligible. Data were systematically extracted on study design, participants, measurements, and findings. The Medical Education Research Study Quality Instrument (MERSQI) was used to assess study quality.

Results

Ultimately, 18 studies were included. Most studies employed an observational design and were of average quality. Most studies reported positive associations of occupational well-being with patient satisfaction, patient adherence to treatment, and interpersonal aspects of patient care. Studies reported conflicting findings for occupational well-being in relation to technical aspects of patient care. One study found no association between occupational well-being and patient health outcomes.

Conclusions

The association between physicians' occupational well-being and health care's ultimate goal-improved patient health-remains understudied. Nonetheless, research up till date indicated that physicians' occupational well-being can contribute to better patient satisfaction and interpersonal aspects of care. These insights may help in shaping the policies on physicians' well-being and quality of care.
