High physician concern about malpractice risk predicts more aggressive diagnostic testing in office-based practice.

Despite widespread agreement that physicians who practice defensive medicine drive up health care costs, the extent to which defensive medicine increases costs is unclear. The differences in findings to date stem in part from the use of two distinct approaches for assessing physicians' perceived malpractice risk. In this study we used an alternative strategy: We linked physicians' responses regarding their levels of malpractice concern as reported in the 2008 Health Tracking Physician Survey to Medicare Parts A and B claims for the patients they treated during the study period, 2007-09.

Comparative effectiveness of care coordination interventions in the emergency department: a systematic review.

Study Objective: To conduct a systematic review on the effectiveness of emergency department (ED)-based care coordination interventions.

Methods: We reviewed any randomized controlled trial or quasi-experimental study indexed in MEDLINE, CINAHL, Web of Science, Cochrane, or Scopus that evaluated the effectiveness of ED-based care coordination interventions. To be included, interventions had to incorporate information from previous visits, provide educational services on continuing care, provide post-ED treatment plans, or transfer information to continuing care providers.

Hospitals' geographic expansion in quest of well-insured patients: will the outcome be better care, more cost, or both?

The emphasis that hospitals place on cutting-edge technology and niche specialty services to attract physicians and patients has set the stage for health care's most recent competitive trend: an increased level of targeted, geographic service expansion to "capture" well-insured patients. We conducted interviews in twelve US communities in 2010 and found that many hospital systems--some with facilities in geographically undesirable areas--have expanded to compete for better-insured patients by building or buying facilities and physician practices in nearby, more affluent communities. Along with extending services to new markets, these hospital outposts often serve to pull well-insured patients to flagship facilities.

Americans' access to prescription drugs stabilizes, 2007-2010.

Despite the weak economy and more people lacking health insurance, the proportion of Americans reporting problems affording prescription drugs remained level between 2007 and 2010, with more than one in eight going without a prescribed drug in 2010, according to a new national study from the Center for Studying Health System Change (HSC). While remaining stable overall, access to prescription drugs improved for working-age, uninsured people, likely reflecting a decline in visits to health care providers, as well as changes in the composition of the uninsured population. Likewise, elderly people eligible for both Medicare and Medicaid saw a sharp drop in prescription drug access problems.

Association between quality of care and the sociodemographic composition of physicians' patient panels: a repeat cross-sectional analysis.

Background: Pay-for-performance programs could worsen health disparities if providers who care for disadvantaged patients face systematic barriers to providing high-quality care. Risk adjustment that includes sociodemographic factors could mitigate the financial incentive to avoid disadvantaged patients.

Objective: To test for associations between quality of care and the composition of a physician's patient panel.

Where Americans get acute care: increasingly, it's not at their doctor's office.

Historically, general practitioners provided first-contact care in the United States. Today, however, only 42 percent of the 354 million annual visits for acute care--treatment for newly arising health problems--are made to patients' personal physicians. The rest are made to emergency departments (28 percent), specialists (20 percent), or outpatient departments (7 percent).

Physicians' fears of malpractice lawsuits are not assuaged by tort reforms.

Physicians contend that the threat of malpractice lawsuits forces them to practice defensive medicine, which in turn raises the cost of health care. This argument underlies efforts to change malpractice laws through legislative tort reform. We evaluated physicians' perceptions about malpractice claims in states where more objective indicators of malpractice risk, such as malpractice premiums, varied considerably.

Substance use treatment barriers for patients with frequent hospital admissions.

Substance use (SU) disorders adversely impact health status and contribute to inappropriate health services use. This qualitative study sought to determine SU-related factors contributing to repeated hospitalizations and to identify opportunities for preventive interventions. Fifty Medicaid-insured inpatients identified by a validated statistical algorithm as being at high-risk for frequent hospitalizations were interviewed at an urban public hospital.
