Latent Semantic Analysis: A new measure of patient-physician communication.

ABSTRACT: RATIONALE:Patient-physician communication plays an essential role in a variety of patient outcomes; however, it is often difficult to operationalize positive patient-physician communication objectively, and the existing evaluation tools are generally time-consuming. OBJECTIVE:This study proposes semantic similarity of the patient's and physician's language in a medical interaction as a measure of patient-physician communication. Latent semantic analysis (LSA), a mathematical method for modeling semantic meaning, was employed to assess similarity in language during clinical interactions between physicians and patients. METHODS:Participants were 132 Black/African American patients (76% women, Mage?=?43.8, range?=?18-82) who participated in clinical interactions with 17 physicians (53% women, Mage?=?27.1, range?=?26-35) in a primary care clinic in a large city in the Midwestern United States. RESULTS:LSA captured reliable information about patient-physician communication: The mean correlation indicating similarity between the transcripts of a physician and patient in a clinical interaction was 0.142, significantly greater than zero; the mean correlation between a patient's transcript and transcripts of their physician during interactions with other patients was not different from zero. Physicians differed significantly in the semantic similarity between their language and that of their patients, and these differences were related to physician ethnicity and gender. Female patients exhibited greater communication similarity with their physicians than did male patients. Finally, greater communication similarity was predicted by less patient trust in physicians prior to the interaction and greater patient trust after the interaction. CONCLUSION:LSA is a potentially important tool in patient-physician communication research. Methodological considerations in applying LSA to address research questions in patient-physician communication are discussed.

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:BackgroundExcellent communication is a necessary component of high-quality health care. We aimed to determine whether a training module could improve patients' perceptions of physician communication behaviors, as measured by change over time in domains of patient experience scores related to physician communication.Study designWe designed a comprehensive physician-training module focused on improving specific "etiquette-based" physician communication skills through standardized simulations and physician coaching with structured feedback. We employed a quasi-experimental pre-post design, with an intervention group consisting of internal medicine hospitalists and residents and a control group consisting of surgeons. The outcome was percent "always" scores for questions related to patients' perceptions of physician communication using the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey and a Non-HCAHPS Physician-Specific Patient Experience Survey (NHPPES) administered to patients cared for by hospitalists.ResultsA total of 128 physicians participated in the simulation. Responses from 5020 patients were analyzed using HCAHPS survey data and 1990 patients using NHPPES survey data. The intercept shift, or the degree of change from pre-intervention percent "always" responses, for the HCAHPS questions of doctors "treating patients with courtesy" "explaining things in a way patients could understand," and "overall teamwork" showed no significant differences between surgical control and hospitalist intervention patients. Adjusted NHPPES percent excellent survey results increased significantly post-intervention for the questions of specified individual doctors "keeping patient informed" (adjusted intercept shift 9.9% P = 0.019), "overall teamwork" (adjusted intercept shift 11%, P = 0.037), and "using words the patient could understand" (adjusted intercept shift 14.8%, p = 0.001).ConclusionA simulation based physician communication coaching method focused on specific "etiquette-based" communication behaviors through a deliberate practice framework was not associated with significantly improved HCAHPS physician communication patient experience scores. Further research could reveal ways that this model affects patients' perceptions of physician communication relating to specific physicians or behaviors.

Project description:Despite the documented benefits of colorectal cancer screening, patient participation rates remain low. Physician recommendation has been identified as a significant predictor of screening completion.The aim of this study is to investigate how primary care physicians perceive colorectal cancer screening communication tasks, as well as to explore the form and content of actual screening discussions.The research design includes a mailed physician survey and a separate observational study in a sample of videotaped medical encounters. PARTICIPANTS AND DATA SOURCES: The participants were 270 primary care physicians who completed a mailed questionnaire (57.9% response rate) and 18 physician-patient encounters that included discussions of colorectal cancer screening.The questionnaire focused on perceived importance and accomplishment of communication tasks relevant to colorectal cancer screening. Two of the authors reviewed transcripts of videotaped physician encounters to determine whether the same communication tasks assessed in the survey were accomplished. Interrater reliability was high across all of the mutually exclusive coding categories (Kappa > .90).Physicians rated colonoscopy as the most important screening option to discuss; self-reports indicate that colonoscopy (84.8%) is more frequently mentioned than fecal occult blood test (FOBT; 49.4%), flexible sigmoidoscopy (34.1%), or computed tomography (CT) imaging (18.1%). Explaining benefits and risks, describing test procedure and frequency, eliciting patient preferences, and making a plan for screening were all viewed as very important. Self-reported accomplishment of these communication tasks was considerably higher than that observed in our separate videotape sample.Most physicians recognize and espouse the importance of recommending colorectal cancer screening to eligible patients. However, findings from both the physician survey and observational study suggest that physicians tend to overestimate the extent of discussions about screening. Interventions may be warranted to improve clinical practice.

Project description:BackgroundThe ratings of physician-patient communication are an important indicator of the quality of health care delivery and provide guidance for many important decisions in the health care setting and in health research. But there is no gold standard to assess physician-patient communication. Thus, depending on the specific measurement condition, multiple sources of variance may contribute to the total score variance of ratings of physician-patient communication. This may systematically impair the validity of conclusions drawn from rating data.ObjectiveTo examine the extent to which different measurement conditions and rater perspectives, respectively contribute to the variance of physician-patient communication ratings.MethodsVariance components of ratings of physician-patient communication gained from 32 general practitioners and 252 patients from 25 family practices in Germany were analyzed using generalizability theory. The communication dimensions "shared decision making", "effective and open communication" and "satisfaction" were considered.ResultsPhysician-patient communication ratings most substantially reflect unique rater-perspective and communication dimension combinations (32.7% interaction effect). The ratings also represented unique physician and rater-perspective combinations (16.3% interaction effect). However, physicians' communication behavior and the observed communication dimensions revealed only a low extent of score variance (1% physician effect; 3.7% communication dimension effect). Approximately half of the variance remained unexplained (46.2% three-way interaction, confounded with error).ConclusionThe ratings of physician-patient communication minimally reflect physician communication skills in general. Instead, these ratings exhibit primarily differences among physicians and patients in their tendency to perceive shared decision making and effective and open communication and to be satisfied with communication, regardless of the communication behavior of physicians. Rater training and assessing low inferential ratings of physician-patient communication dimensions should be considered when subjective aspects of rater perspectives are not of interest.

Project description:BackgroundEffective communication with health care providers has been found as relevant for physical and psychological health outcomes as well as the patients' adherence. However, the validity of the findings depends on the quality of the applied measures. This study aimed to provide an overview of measures of physician-patient communication and to evaluate the methodological quality of psychometric studies and the quality of psychometric properties of the identified measures.MethodsA systematic review was performed to identify psychometrically tested instruments which measure physician-patient communication. The search strategy included three databases (EMBASE, PsycINFO, PubMed), reference and citation tracking and personal knowledge. Studies that report the psychometric properties of physician-patient communication measures were included. Two independent raters assessed the methodological quality of the selected studies with the COSMIN (COnsensus based Standards for the selection of health status Measurement INtruments) checklist. The quality of psychometric properties was evaluated with the quality criteria of Terwee and colleagues.ResultsData of 25 studies on 20 measures of physician-patient communication were extracted, mainly from primary care samples in Europe and the USA. Included studies reported a median of 3 out of the nine COSMIN criteria. Scores for internal consistency and content validity were mainly fair or poor. Reliability and structural validity were rated mainly of fair quality. Hypothesis testing scored mostly poor. The quality of psychometric properties of measures evaluated with Terwee et al.'s criteria was rated mainly intermediate or positive.DiscussionThis systematic review identified a number of measures of physician-patient communication. However, further psychometric evaluation of the measures is strongly recommended. The application of quality criteria like the COSMIN checklist could improve the methodological quality of psychometric property studies as well as the comparability of the studies' results.

Project description:BackgroundThe Gene Ontology (GO) is a dynamic, controlled vocabulary that describes the cellular function of genes and proteins according to tree major categories: biological process, molecular function and cellular component. It has become widely used in many bioinformatics applications for annotating genes and measuring their semantic similarity, rather than their sequence similarity. Generally speaking, semantic similarity measures involve the GO tree topology, information content of GO terms, or a combination of both.ResultsHere we present a new semantic similarity measure called TopoICSim (Topological Information Content Similarity) which uses information on the specific paths between GO terms based on the topology of the GO tree, and the distribution of information content along these paths. The TopoICSim algorithm was evaluated on two human benchmark datasets based on KEGG pathways and Pfam domains grouped as clans, using GO terms from either the biological process or molecular function. The performance of the TopoICSim measure compared favorably to five existing methods. Furthermore, the TopoICSim similarity was also tested on gene/protein sets defined by correlated gene expression, using three human datasets, and showed improved performance compared to two previously published similarity measures. Finally we used an online benchmarking resource which evaluates any similarity measure against a set of 11 similarity measures in three tests, using gene/protein sets based on sequence similarity, Pfam domains, and enzyme classifications. The results for TopoICSim showed improved performance relative to most of the measures included in the benchmarking, and in particular a very robust performance throughout the different tests.ConclusionsThe TopoICSim similarity measure provides a competitive method with robust performance for quantification of semantic similarity between genes and proteins based on GO annotations. An R script for TopoICSim is available at http://bigr.medisin.ntnu.no/tools/TopoICSim.R .
