DATA BY TOPIC

Medicare Reimbursements

Medicare spending varies more than twofold among hospital referral regions. Spending also varies from state to state, and from one hospital to another, even among hospitals within the same region. Most of this variation is not due to differences in the price of care in different parts of the country, but rather to differences in the volume, or the amount of inpatient care delivered per patient.

Variation in the Care of Surgical Conditions

These indicators were created for a series of six Dartmouth Atlas reports that examine unwarranted variations in U.S. surgical care. The topics include surgical treatments for obesity, cerebral aneurysms, diabetes/peripheral artery disease, spinal stenosis, organ failure (transplantation), and prostate cancer.

Children's Health Care

This section examines small area variations in children's health care in Northern New England for ambulatory physician services, hospitalization, common surgery, imaging, and outpatient prescription fills. The measures are presented by hospital service area and pediatric surgical area, revealing the care provided by specific hospitals and their medical staffs.

Prescription Drug Use in Medicare Part D

Prescription medications are an increasingly important component of health care. Many drugs are highly effective at treating or preventing disease, while others have benefits that are less clear and may be outweighed by potential adverse effects. Regional variation in the use of prescription drugs suggests that these benefits and risks are not uniformly delivered to Medicare patients.

Care of Chronic Illness in Last Two Years of Life

Caring for people with chronic disease accounts for more than 75% of health care spending. As chronic disease progresses, the amount of care delivered and the costs associated with this care increase dramatically. Patients with chronic illness in their last two years of life account for about 32% of total Medicare spending, with much of it going toward physician and hospital fees associated with repeated hospitalizations.

Hospital Use

Most hospitalizations are for conditions that have high or very high patterns of variation in their discharge rates. Medical discharges are more variable than surgical discharges. For medical conditions, the majority of variation is associated with hospital capacity (as measured by the per capita supply of hospital beds).

Medical Discharges

For patients with medical conditions, geography matters; patients with medical conditions receive very different care depending upon where they live. Why does care vary so much? The most obvious explanation might seem to be regional differences in how sick patients are. But the prevalence and severity of illness accounts for remarkably little of the variation in care.

Surgical Procedures

Most patients defer to their physicians when it comes to deciding what care they receive. When it comes to elective surgery, physician opinion can vary widely as to when the treatment is necessary, and which patients are appropriate. Consequently, the frequency of discretionary surgery such as knee or hip replacement or back surgery, also varies remarkably from one region to another.

Post-Acute Care

Improving care coordination after discharge from the hospital is important to patients, to hospitals and to Medicare. Without high-quality care coordination, patients can bounce from home to the emergency room and back into the hospital, sometimes repeatedly. Better care coordination promises to reduce readmission rates and improve patients' lives while reducing costs.

Quality/Effective Care

Effective care consists of evidence-based interventions for which the benefits so far exceed the harms that all patients in need should receive the service. Life-saving drugs following heart attack are examples. Variations in the use of such treatments among eligible patients reflect a failure to deliver needed care, or underuse.

Hospital & Physician Capacity

Regional variation in hospital and physician capacity reveals the irrational distribution of valuable and expensive health care resources. Capacity strongly influences both the quantity and per capita cost of care provided to patients. Better planning of future growth in capacity can help build a more effective and affordable health care system.

End of Life Care

Modern technology has vastly extended the ability to intervene in the lives of patients, most dramatically so when life itself is at stake. But the capability to intervene is not uniformly deployed, and health care providers do not share a uniform propensity to hospitalize dying patients or to use technology at the end of life. The American experience of death varies remarkably from one community to another.
