Report Cards and Feedback for PCCE

The investigators will use a communication strategy that leverages behavioral principles to motivate providers to improve in all four of the evaluated domains of the PCCE program: clinical quality, professional participation, patient experience, and risk coding.

The investigators will implement a three-arm experimental communication campaign that includes quarterly emails and quarterly survey messages. The communication strategies will utilize motivation and behavior change theories to improve physician performance in the program and attitudes towards the program. In particular, the investigators will test the independent and joint effects of communicating with physicians (a) personalized performance feedback and (b) the "co-creation" of the program (i.e., sharing how physician feedback informed the program design).

The investigators will randomly assign eligible physicians to one of the three experimental arms, stratified by overall baseline performance (the total percent allocated in the PCCE program for the April, May, June 2023 quarter), specialty (based on classification as Adult or Adult/Peds), and contract (based on classification as DOM or PCN (CPN/EIMG)).

The investigators will evaluate whether arm 3 differs from arm 1 in terms of the measures listed in the Outcome Measures section. If this comparison is statistically significant, the investigators will next compare arms 3 vs. 2 and arms 2 vs. 1.

Analysis plan

• Physician-quarter-level linear regression models with heteroskedastic-consistent robust standard errors, clustered at the physician level.
• The primary model term will be indicator variables for arms that patients are assigned to.
• Control variables:
• Baseline values of the outcome measure: the investigators will control for the baseline measures of the outcomes, based on performance from July through September 2023 and survey responses in April and July 2023, if available.
• Physician baseline subjective understanding of the PCCE program from the July 2023 survey, with four items which asked the extent to which physicians understood how their score in each domain of the program was calculated.
• Physician characteristics: self-reported gender, race, and age, plus years at UCLA Health and clinic from administrative data
• Missing covariate values will be handled by including 'unknown' indicator variables, along with mean imputation for continuous covariates.
• Exploratory analyses will investigate heterogeneous treatment effects by the following characteristics:
• Physician baseline performance in the PCCE program (evaluated based on performance in July, August, and September 2023)
• Physician baseline perceived leadership support reported in the July 2023 survey
• Physician baseline program-related attitudes (agency, value in PCCE program) reported in the April 2023 survey
• Physician baseline subjective understanding of the PCCE program from the July 2023 survey
• Objective valence of the feedback delivered in the first email report card, measured by 1) the number of metrics within each domain for which the physician improved relative to the prior quarter, 2) the number of metrics within each domain for which the physician met or exceeded the benchmark, and 3) average distance from the benchmark across the metrics within each domain
• Random assignment to providing feedback on the report card design in a survey conducted before the intervention launch, in July 2023
• Physician gender
• Physician years in practice
• The investigators will investigate physicians' program-related attitudes and perceptions as proposed mechanisms of the interventions. These will be measured with 11 items that form three subscales about perceived justice, antecedents to one's intentions to succeed, and perceived value of the feedback.
• Perceived justice in the PCCE program structure and implementation: Physicians will be surveyed regarding the structural justice (2 items), distributive justice (1 item), and informational justice of the program (2 items).
• Antecedents of intentions to succeed in the program: Physicians will be surveyed regarding their perceived agency (behavioral control) over their performance in the PCCE program (1 item), their perceived value of the PCCE program (2 items), and their subjective norms about the endorsement and success of their colleagues in the program (2 items).
• Perceived value of the performance feedback: Physicians will be surveyed about the utility of the quarterly performance feedback in contextualizing their goal pursuit efforts (1 item).
• The investigators will investigate physicians' overall workplace attitudes as additional outcomes. These will be measured as a 4-item questionnaire about trust in UCLA Health leadership (1 item), perceived leadership support (1 item), job satisfaction (1 item), and burnout (1 item).
• Robustness checks will be performed without covariates, and using logistic regression models in place of linear regression models for dependent variables that are measured as binary indicators.
