The authors specified loss functions and evaluated the potential cost of misclassification for physician report card designs. They found that misclassification cost depends on how performance information will be used and by whom; selecting the lowest-cost design for a given stakeholder could maximize the usefulness of physician performance data. They conlcuded that misclassification cost could guide report card design, improving the usefulness of a report card for one stakeholder without disadvantaging others.

Patient-centered mobility outcome preferences according to individuals with stroke and caregivers: a qualitative analysis.
This study explored the mobility-related preferences among stroke survivors and caregivers following post-acute rehabilitation at inpatient or skilled nursing facilities. Frequently mentioned outcome preferences by survivors were ability to walk (88 percent), move, and balance. They also wanted to acquire assistive devices to move independently. Caregivers were concerned with the survivor's safety and wanted them to drive (53 percent), prevent falls, have home accommodations, and transfer independently.

Racial, ethnic, and nativity differences in mental health visits to primary care and specialty mental health providers: analysis of the Medical Expenditures Panel Survey, 2010-2015.
The researchers sought to guide post-ACA efforts to address mental health service disparities, by using a nationally representative sample to characterize baseline race-, ethnicity-, and nativity-associated differences in mental health services in the context of primary care. They found that all racial/ethnic groups were less likely than non-Latino Whites to have any primary care (PC) visit. Their conclusion was that racial-, ethnic-, and nativity-associated disparities persist in PC provided mental health services.

Mandatory physician reporting of at-risk drivers: the older driver example.
The hypothesis that mandatory physician reporting laws reduce the rate of crash-related hospitalizations among older adult drivers was tested. Mandatory physician reporting failed to explain any significant variation in crash hospitalization rates, when adjusting for other state-specific laws and characteristics. Vision testing at in-person license renewal was a significant predictor of lower crash hospitalization rate.

Accuracy and reliability of emergency department triage using the emergency severity index: an international multicenter assessment.
This study assessed the accuracy and variability of triage score assignment by emergency department (ED) nurses using the Emergency Severity Index (ESI) in 3 countries. It found that the concordance of nurse-assigned ESI score with reference standard was universally poor and variability was high. Although the ESI is the most popular ED triage tool in the United States and is increasingly used worldwide, its findings point to a need for more reliable ED triage tools.

Second arterial versus venous conduits for multi-vessel coronary artery bypass surgery in California.
This study sought to determine whether a second arterial conduit improves outcomes after multi-vessel coronary artery bypass grafting. It concluded that second arterial conduit use in California is low and declining, but arterial grafts were associated with significantly lower mortality and fewer cardiovascular events. A right internal thoracic artery graft offered no benefit over that of a radial artery, but did increase risk of sternal wound infection.

Does information from increase transparency and reduce bias? Results from a five-report case series.
The researchers investigated whether information in would impact the conclusions of five ongoing systematic reviews. Of the 173 total records identified across the five projects, between 11 and 43 percent did not have an associated publication. In the 14 percent of records that contained results, the new data provided in the records did not change the results or conclusions of the reviews.

Association between quality domains and health care spending across physician networks.
One of the more fundamental health policy questions is the relationship between health care quality and spending. Researchers measured 65 validated quality indicators (QI) across Ontario physician networks. Higher physician spending, especially outpatient primary care spending, was associated with lower rates of avoidable hospitalizations and higher rates of timely hospital-community transitions and moderately associated with lower readmission rates.

Challenges in communication from referring clinicians to pathologists in the electronic health record era.
This study reports on the role played by electronic health record inbox messages (EHRmsg) in a safety event involving pathology. Clinicians assumed that pathologists used EHRmsg as clinical care team members, however, pathologists rarely did. Communication gaps exist between primary clinicians and pathologists in the EHR era and they have potential to result in patient harm.
