Background and Context Research Question and Proposition Swiss Federal Institute of Technology Assessing Health Providers’ ‘Patient Identity’ Matthew J Kerry, Ph.D. Embrace the cultural diversity and individual differences that characterize patients, populations, and the health care team -- Interprofessional Education Collaborative (IPEC) Background and Context As the health of any labor force has economic effects, conversely, the economy of any health system has clinical consequences. The shift to value-based compensation systems in care-services delivery compels new provider competencies (IPE, team).   It also signals a reemphasis on the provider-patient relationship and its importance for: Clinical efficacy (Kelly et al., 2014; Hughes et al., 2016;), patient safety (Kerry et al., 2017) Economic sustainability (Okunrintemi et al., 2017) Drawing on the Common-Ingroup Identity Model from social psych, Patient Identity is a construct similar to empathy, and it has been defined as “a provider’s perspective for regulating professional competence with patient values, interests, and beliefs” - Kerry et al. 2016, p.2 The main goal of the following studies was to leverage rich organizational-identity for assessing if PatID may be viably measured via a short, self-report  Research Question and Proposition Question  Is there a need for a provider-reported measure that may be useful in the value-compensation model overhaul? If yes, can an adapted identity instrument suffice for baseline? Proposition  PatID indicates a health provider’s (doctor / nurse) level of identification with their patients, reflecting more personalized medical practices, such as shared-decision making (SDM), teamwork preferences, and stronger patient-safety attitudes. Study 1 Study 2 cont . . . Feasibility study of PatID Assessment via self-report, psychometrics? Distinguishable from Professional ID (ProID)? Exploratory S1 Goals Medical and nursing students (N=133) Before-after design, survey-based questionnaire Measures: ProID, PatID, Interprofessional Readiness (RIPLS), S2 Protocol Table 2 Summary Sample-Descriptive Statistics for S1 and S2   Sample (N) Variable Mean (S.D.)

H1b: PatID will correlate positively with SDM, SafClim, and AmbTol. H2: PatID will add incremental-predictive validity over JeffEmp for SDM, SafClim, and AmbTol H3a: Practitioners will score higher on PatID compared to students. H3b: Providers working in general practice will score higher on PatID compared to specialty practices. Study 2 German-translation / measurement-invariance?
