While working to develop a broad set of outcome measures that can be the basis for attaining the goals of public accountability and information for consumer choice, Medicare should ensure that the use of performance measures supports quality improvement efforts to address important deficiencies in how care is provided, not only to Medicare beneficiaries but to all Americans.
CMS’ current focus on reducing preventable rehospitalizations within 30 days of discharge represents a timely, strategic use of performance measurement to address an evident problem where there are demonstrated approaches to achieve successful improvement . Physicians and hospital clinical staff, if not necessarily hospital financial officers, generally have responded quite positively to the challenge of reducing preventable readmissions.
CMS has complemented the statutory mandate to provide financial incentives to hospitals to reduce readmission rates by developing new service codes in the Medicare physician fee schedule that provide payment to community physicians to support their enhanced role in assuring better patient transitions out of the hospital in order to reduce the likelihood of readmission . CMS recently announced that after hovering between 18.5 percent and 19.5 percent for the past five years, the 30-day all-cause readmission rate for Medicare beneficiaries dropped to 17.8 percent in the final quarter of 2012 , simplying some early success with efforts to use performance measures as part of a broad quality improvement approach to improve a discrete and important quality and cost problem.
However, this Timely Analysis of Immediate Health Policy Issues 3“CMS’ current value-based purchasing efforts, requiring reporting on a raft of measures of varying usefulness and validity, should be replaced with the kind of strategic approach used in the national effort to reduce bloodstream infections.”approach is not without controversy.
Improvements have been modest, and some suggest that readmission rates are often outside the hospital’s control, so CMS’ new policy unfairly penalizes hospitals that treat patients who are the sickest . And while readmission in surgical patients is largely related to preventable complications, readmissions in medical patients can be related to socioeconomic status. Also, some have questioned the accuracy of CMS’ seemingly straightforward readmission rate measure, finding that some hospitals reduce both admissions and readmissions—a desirable result—yet do not impact the readmission rate calculation . And one of this paper’s authors (R. Berenson) has suggested a very different payment model that would reward hospital improvement rather than absolute performance, thereby addressing the reality that hospitals’ abilities to influence readmission rates do vary by factors outstside of their control .
Here’s a quiz for Patient Safety Awareness Week (and after): The number of Americans who die annually from preventable medical errors is:
A) 44,000-98,000, according to the Institute of Medicine
B) None, thanks to the Institute for Healthcare Improvement’s “100,000 Lives Campaign”
D) No one’s really counting
The correct answer is, “D,” but I confess it’s a trick question. With a slight twist in wording, the right answer could also be “C,” from an as-yet-unpublished new estimate with a unique methodology. (More below.) The main point of this quiz, however, is to explore what we actually know about the toll taken by medical mistakes and to dispel some of the confusion about the magnitude of harm.
Answer “A” refers to a figure in the oft-quoted (and often incorrectly quoted) 1999 IOM report, To Err is Human. The IOM estimate of 44,000-98,000 deaths and more than 1 million injuries each year refers only to preventable errors, and then just in hospitals. The quiz asked about all preventable harm. As the sophistication and intensity of outpatient care has increased, so, too, have the potential dangers.
For example, the Centers for Disease Control and Prevention (CDC) reported in 2011 that the majority of central-line associated bloodstream infections (CLABSIs) “are now occurring outside of ICUs, many outside of hospitals altogether, especially in outpatient dialysis clinics.” CLABSIs are both highly expensive and kill up to 25 percent of those who get them. Even in garden-variety primary care, one analysis found a harm rate of one per 35 consultations, with medication errors the most common problem. To Err is Human was silent about those types of hazards.
The Medicare program is betting on a new course of action to curb what one medical journal has dubbed an “epidemic” of uncontrolled patient harm.
The effort is pegged to the success of a little-known entity called a “hospital engagement network” (HEN). In December, the government selected 26 HENs and charged them with preventing more than 60,000 deaths and 1.8 million injuries from so-called “hospital-acquired conditions” over the next three years. That would be the equivalent of eliminating all deaths from HIV/AIDS or homicide over the same period.
Despite those big numbers, and an initial price tag of $218 million, it’s unclear whether the HENs are adequately ambitious or still only pecking away at the patient safety problem. While this is by far the most comprehensive public or private patient safety effort ever attempted in this country, it still aims to eliminate less than half the documented, preventable patient harm.
The inspiration for these networks comes from similar collaborative projects run by the Institute for Healthcare Improvement and other groups. Dr. Donald Berwick, IHI’s founder and president, headed up the Centers for Medicare & Medicaid Services for two years and launched a larger Partnership for Patients that includes the HENs.
In December, the government chose a mix of national and local groups — primarily health systems and hospital organizations — to run individual HENs. Each HEN is charged with spreading safety-improvement innovations that have been proven to work in leading hospitals to others through intensive training programs and technical assistance. Although the program lasts three years, initial HEN contracts are for two years, with an “option year” dependent upon performance.
My wife was lying in the back of an ambulance, dazed and bloody, while I sat in the front, distraught and distracted. We had been bicycling in a quiet neighborhood in southern Maine when she hit the handbrakes too hard and catapulted over the handlebars, turning our first day of vacation into a race to the nearest hospital.
The anxiety when a loved one is injured is compounded when you know just how risky making things better can get. As a long-time advocate for patient safety, my interest in the topic has always been passionate, but never personal. Now, as Susan was being rushed into the emergency room, I wanted to keep it that way. “Wife of patient safety expert is victim” was a headline I deeply hoped to avoid.
In the weeks after the accident, we spent time at a 50-bed hospital in Maine; a Boston teaching hospital where Susan was transferred with a small vertebra fracture at the base of her neck and broken bones in her left elbow and hand; and a large community hospital near our suburban Chicago home. There were plenty of opportunities for bad things to happen – but nothing did. As far as I could tell, we didn’t even experience any near misses.
What went right? After all, though our health care system knows how to prevent errors that kill 44,000 to 98,000 people in hospitals each year, that death toll has remained stubbornly constant. Based on personal and professional observations, I’d simplify the formula that kept Susan safe into three variables: consciousness, culture and cash.
