How they were ranked
Of the 16 specialty rankings, 12 were driven mostly by hard data, with the other four based on three years of nominations by surveyed specialists. Only hospitals that met one of three requirements—membership in the Council of Teaching Hospitals, affiliation with a medical school, or availability of at least six of 13 key technologies such as robotic surgery—were considered for the data-driven rankings, leaving out nearly two-thirds of all US hospitals.
To be eligible, a hospital had to have performed a certain number of procedures that varied by specialty—for example 294 procedures for orthopedics—on Medicare inpatients in 2004, 2005, and 2006. Or, it had to have been nominated by at least one doctor who participated in the USNWR surveys in 2006, 2007, or 2008. The remaining 1,569 hospitals that were eligible to be ranked were then given a score from 0-100 based on the following:
• Reputation: A random sampling of 200 doctors for each of the 16 specialties listed the five hospitals they considered the best in their specialty, without considering cost or location
• Mortality index: Compares the number of Medicare inpatients with certain conditions who died within 30 days of admission with the number that would have been expected after adjusting for severity.
• Other care-related factors: Looks at technology, volume, nurse staffing, and other patient-related information.
A hospitalist—high rank correlation?
Johns Hopkins—ranked number one by the has eight physicians in its hospitalist program, whereas the University of Michigan Hospital and Mott’s Children’s Hospital—part of the University of Michigan Hospitals and Health Centers, which ranked 13th—together have 40 full- or part-time hospitalists, significantly more than the top-ranking Hopkins. Is there a correlation between a ranking and a commitment to hospitalist medicine and the focus on quality and continuity of care that comes with it? Does the presence of a hospitalist program, regardless of the number of physicians within it, do anything to put a hospital at the top of the list? Does the presence of a hospitalist program inherently elevate the quality of a hospital?
Does it matter?
Are these rankings even useful? Are they leaving so many other factors out of consideration that they don’t mean anything? What are these factors? Should your hospital have ranked higher? Was a hospital not even ranked because of some of the exclusions set by , leaving off an otherwise excellent facility? Do patients look at these rankings and request to their physician to undergo a procedure at a given hospital accordingly? Is Johns Hopkins really that good (ranked at the top for 18 years running), or is the ranking system flawed and/or biased in some way? How badly does a focus on specialties, not on general/internal medicine, hurt the quality of the rankings?
