Defining Objective Measures of Physician Stress in Simulated Critical Communication Encounters.

ABSTRACT: This study had three aims: 1) quantify the difference in stress levels between low and high stress roles during simulated critical communication encounters using objective physiologic data (heart rate variability [HRV]) and subjective measures (State-Trait Anxiety Inventory [STAI]), 2) define the relationship between subjective and objective measures of stress, and 3) define the impact of trainee preparedness and reported self-efficacy on stress levels.

Design

Mixed methods simulation-based study.

Setting

Single center.

Patients

Pediatric critical care fellows and faculty (n = 12).

Interventions

Subjects participated in six simulated scenarios in both high stress "hot seat" and low stress "observer" roles.

Measurements and main results

Subjective stress was measured using the STAI at baseline and after each scenario. Objective stress was measured continuously using a wearable biometric device measuring HRV. Previous residency communication training and self-confidence surrounding various communication topics were collected via questionnaire. Significant changes in subjective (STAI) and objective stress (HRV) measurements in the low- versus high-stress roles were observed. STAI scores increased 8 points during low stress and 12 points during high stress role (p = 0.021) compared with baseline. Two specific HRV markers, root mean square of successive differences between normal heartbeats, a marker of parasympathetic tone, and the low frequency/high frequency (LF/HF) ratio, a marker of sympathetic activation, were significantly correlated with STAI levels (-0.032, p = 0.001; 1.030, p = 0.002, respectively). Participants who reported increased confidence in discussing code status had a significant decrease in stress response (measured via LF/HF ratio) during both the observer (p = 0.033) and hot seat roles (p = <0.001).

Conclusions

Communicating life-altering news in a simulated environment is a stressful experience. This stress results in physiologic changes that can be measured continuously using HRV. HRV measurement may serve as a novel method in evaluating the effectiveness of communication training programs and measuring future stress-reduction interventions.

Project description:Although previous studies suggest an association between provider burnout and suboptimal self-reported communication, no studies relate physician burnout to observed patient-physician communication behaviors.To investigate the relationship between physician burnout and observed patient-physician communication outcomes in patient-physician encounters.Longitudinal study of enrollment data from a trial of interventions to improve patient adherence to hypertension treatment.Fifteen urban community-based clinics in Baltimore, MD.Forty physicians and 235 of their adult hypertensive patients, with oversampling of ethnic minorities and poor persons. Fifty-three percent of physicians were women, and the average practice experience was 11.2 years. Among the 235 patients, 66% were women, 60% were African-American, and 90% were insured.Audiotape analysis of communication during outpatient encounters (one per patient) using the Roter Interaction Analysis System and patients' ratings of satisfaction with and trust and confidence in the physician.The median time between the physician burnout assessment and the patient encounter was 15.1 months (range 5.6-30). Multivariate analyses revealed no significant differences in physician communication based on physician burnout. However, compared with patients of low-burnout physicians, patients of high-burnout physicians gave twice as many negative rapport-building statements (incident risk ratio 2.06, 95% CI 1.58-2.86, p < 0.001). Physician burnout was not significantly associated with physician or patient affect, patient-centeredness, verbal dominance, or length of the encounter. Physician burnout was also not significantly associated with patients' ratings of their satisfaction, confidence, or trust.Physician burnout was not associated with physician communication behaviors nor with most measures of patient-centered communication. However, patients engaged in more rapport-building behaviors. These findings suggest a complex relationship between physician burnout and patient-physician communication, which should be investigated and linked to patient outcomes in future research.

Project description:ObjectiveTo assess physician-patient communication in vascular consults with the aim of identifying areas for improvement.IntroductionShared decision-making in clinical consults can enhance patient outcomes. Its potential benefits are significant in vascular surgery, where decisions are dependent on the patient's definition of quality of life and outcomes are influenced by significant lifestyle changes.MethodsIn this qualitative cross-sectional study, encounters between five vascular surgeons and their patients with two asymptomatic vascular diseases were audio recorded, transcribed, and analyzed for validated sociolinguistic statistics. The nine-item shared decision-making questionnaire was used to gauge subjective patient perspective.ResultsPhysicians spent an average of 19 min and 28 s (±8:55) per consult and an average of 12 min and 7 s talking to the patient (±6:33). Physicians used formalized language about 10.3 times an encounter (±8.39), checked for understanding 6.4 times (±4.84), and asked more close-ended than open-ended questions (10.5 ± 6.15 versus 4.6 ± 2.37). Physicians accounted for 46.34% of utterances (±6%) and averaged 5.8 interruptions per encounter (±4). Patients and company accounted for 53.66% of total utterances (±6%) and averaged 10.1 clarification questions (±9.78). The average nine-item shared decision-making questionnaire Likert-type score per patient was 2.82 on a range of -3 to +3 (±0.33), with positive numbers indicating agreement. On average, patients strongly (+2) or completely (+3) agreed that physicians covered the nine criteria.ConclusionThe 9-item shared decision-making questionnaire data showed that patients mostly felt their physician was adequate in exhibiting shared decision-making behaviors. However, physicians asked closed-ended questions that elicited "yes/no" or brief responses, continuously interrupted patient narratives, and rarely checked for understanding from their patients. These subliminal behaviors restrict patient participation in shared decision-making and may be corrected via longitudinal intervention.

Project description:BackgroundWith the increasing adoption of electronic health record (EHR) systems, documentation-related burdens have been increasing for health care providers. Recent estimates indicate that primary care providers spend about one-half of their workdays interacting with the EHR, of which about half is focused on clerical tasks. To reduce documentation burdens associated with the EHR, health care systems and physician practices are increasingly implementing medical scribes to assist providers with real-time documentation. Scribes are typically unlicensed paraprofessionals who assist health care providers by documenting notes electronically under the direction of a licensed practitioner or physician in real time. Despite the promise of scribes, few studies have investigated their effect on clinical encounters, particularly with regard to patient-provider communication.ObjectiveThe purpose of this quasi-experimental pilot study was to understand how scribes affect patient-physician communication in primary care clinical encounters.MethodsWe employed a convergent mixed methods design and included a sample of three physician-scribe pairs and 34 patients. Patients' clinical encounters were randomly assigned to a scribe or nonscribe group. We conducted patient surveys focused on perceptions of patient-provider communication and satisfaction with encounters, video recorded clinical encounters, and conducted physician interviews about their experiences with scribes.ResultsOverall, the survey results revealed that patients across both arms reported very high satisfaction of communication with their physician, their physician's use of the EHR, and their care, with very little variability. Video recording analysis supported patient survey data by demonstrating high measures of communication among physicians in both scribed and nonscribed encounters. Furthermore, video recordings revealed that the presence of scribes had very little effect on the clinical encounter.ConclusionsFrom the patient's perspective, scribes are an acceptable addition to clinical encounters. Although they do not have much impact on patients' perceptions of satisfaction and their impact on the clinical encounter itself was minimal, their potential to reduce documentation-related burden on physicians is valuable. Physicians noted important issues related to scribes, including important considerations for implementing scribe programs, the role of scribes in patient interactions, how physicians work with scribes, characteristics of good scribes, and the role of scribes in physician workflow.

Project description:BackgroundThis study investigates patient-centered mobile health (mHealth) technology in terms of the secondary user experience (UX). Specifically, it examines how personal mobile technology, under patient control, can be used to improve patient-provider communication about the patient's health care during their first visit to a provider. Common ground, a theory about language use, is used as the theoretical basis to examine interactions. A novel concept of this study is that it is one of the first empirical studies to explore the relative meaningfulness of a secondary UX for specific health care tasks.ObjectiveThe objective of this study was to investigate the extent that patient-operated mHealth technology can be designed to improve the communication between the patient and provider during an initial face-to-face encounter.MethodsThe experimental study was conducted in 2 large Midwestern cities from February 2016 to May 2016. A custom-designed smartphone app prototype was used as the study treatment. The experimental design was posttest-only control group and included video-recorded simulated face-to-face clinical encounters in which an actor role-played a patient. Experienced clinicians consisting of doctors (n=4) and nurses (n=8) were the study participants. A thematic analysis of qualitative data was performed. Quantitative data collected from time on task measurements were analyzed using descriptive statistics.ResultsThree themes that represent how grounding manifested during the encounter, what it meant for communication during the encounter, and how it influenced the provider's perception of the patient emerged from the qualitative analysis. The descriptive statistics were important for inferring evidence of efficiency and effectiveness of communication for providers. Overall, encounter and task times averaged slightly faster in almost every instance for the treatment group than that in the control group. Common ground clearly was better in the treatment group, indicating that the idea of designing for the secondary UX to improve provider outcomes has merit.ConclusionsCombining the notions of common ground, human-computer interaction design, and smartphone technology resulted in a prototype that improved the efficiency and effectiveness of face-to-face collaboration for secondary users. The experimental study is one of the first studies to demonstrate that an investment in the secondary UX for high payoff tasks has value but that not all secondary UXs are meaningful for design. This observation is useful for prioritizing how resources should be applied when considering the secondary UX.

Project description:BackgroundPhysician assistants/associates (PAs) are a recent innovation in acute hospital teams in England and many other countries worldwide. Although existing evidence indicates generally high levels of patient satisfaction with their PA hospital encounters, little is known about the factors associated with this outcome. There is a lack of evidence on the process of PA-patient communication in hospital encounters and how this might influence satisfaction. This study therefore aimed to understand patients' satisfaction with PA acute hospital encounters through PA-patient communication experiences.MethodsA qualitative study was conducted among patients and representatives of patients seen by or receiving care from one of the PAs working in acute hospital services in England. Semi-structured interviews were undertaken face-to-face with study participants in the hospital setting and shortly after their PA encounter. Data were coded and analysed using thematic analysis. The study was framed within a theoretical model of core functions of medical encounter communication.ResultsFifteen patients and patient representatives who had experienced a PA encounter participated in interviews, across five hospitals in England. Four interrelated communication experiences were important to participants who were satisfied with the encounter in general: feeling trust and confidence in the relationship, sharing relevant and meaningful information, experiencing emotional care and support, and sharing discussion on illness management and treatment. However, many participants misconceived PAs to be doctors, raising a potential risk of reduced trust in the PA relationship and negative implications for satisfaction with their PA encounter. Participants considered it beneficial that patients be informed about the PA role to prevent confusion.ConclusionsPA encounters offer a constructive example of successful clinician-patient communication experiences in acute hospital encounters from the patient's perspective. Study participants were generally naïve to the PA role. Hospital services and organisations introducing these mid-level or advanced care practitioner roles should consider giving attention to informing patients about the roles.
