Medicare’s Hospital Compare website evaluates hospital quality.  One of the most recent measures to be added to Hospital Compare is a measure of efficiency.  The measure calculates a price-standardized, case-mix adjusted measure of spending during period before, during and after a hospital admission. The Healthcare Economist (Jason Shafrin) and a team at Acumen (including Tom MaCurdy, Sajid Zaidi, Elen Shrestha, and David Pham) worked closely with CMS to develop this measure.  Additional information on this measure is available here or see the results for San Francisco General Hospital here.

The Spending per Hospital Patient with Medicare measure shows whether Medicare spends more, less, or about the same per Medicare patient treated in a specific hospital, compared to how much Medicare spends per patient nationally. This measure includes any Medicare Part A and Part B payments made for services provided to a patient during the 3 days prior to the hospital stay, during the stay, and during the 30 days after discharge from the hospital.

This result is a ratio calculated by dividing the amount Medicare spends per patient for an episode of care initiated at this hospital by the median (or middle) amount Medicare spent per patient nationally.

A result of 1 means that Medicare spends ABOUT THE SAME amount per patient for an episode of care initiated at this hospital as it does per hospital patient nationally.

A result that is more than 1 means that Medicare spends MORE per patient for an episode of care initiated at this hospital than it does per hospital patient nationally.

A result that is less than 1 means that Medicare spends LESS per patient for an episode of care initiated at this hospital than it does per hospital patient nationally.

Lower numbers are better.

Medicare payments for End Stage Renal Disease rely on a value-based purchasing (VBP) system known as the Quality Incentive Program (QIP). Today I review proposed changes to the QIP that will effect the payments for dialysis centers in 2013 and 2014.

Payment Year 2013

Two measures have been adopted for the payment year (PY) 2013 ESRD QIP

  • Percentage of patients with hemoglobin levels greater than 12 g/dL (Hemoglobin Greater Than 12 g/dL) Lower percentage indicates better care
  • Percentage of patients with a Urea Reduction Ratio (URR) of 65% or greater (Hemodialysis Adequacy) Higher percentage indicates better care

To qualify for a score, facilities must have at least 11 patients eligible for each measure.

Each facility that meets or exceeds performance standard for a measure receives 10 points (for each measure).  For other facilities, the scoring is more complex.

  • Facility does not meet the performance standard for a measure: 2 points subtracted from 10 points for every 1% below the performance standard
  • Total Performance Score = Sum of the Two Measure Scores x 1.5

The payment reduction for payment year 2013 depend on the total performance score (TPS) as follows:

  • 30 points: 0%
  • 26-29 points: 1.0%
  • 21-25 points: 1.5%
  • <21 points: 2.0%

 

Payment Year 2014

In PY 2014, the ESRD QIP will add one clinical measure (vascular access type (VAT)) and three reporting measures.  The reporting measures include:

  • Dialysis event data submission to the Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network (NHSN) system
  • Patient Satisfaction (measured by In-center Hemodialysis Consumer Assessment of Healthcare Providers and Systems (ICH CAHPS) survey)
  • Monthly mineral metabolism monitoring (serum calcium and serum phosphorus)

For PY 2014, there is a significant lag between when the data are collected and when payments are adjusted.  PY 2014 is based off a performance period of CY2012 and a baseline period of July 1, 2010 to June 30, 2011.  The baseline data is used to measure an improvement score.

 

The payment reduction for payment year 2014 depend on the total performance score (TPS) as follows:

  • 53-100 points: 0%
  • 43-52 points: 0.5%
  • 33-42 points: 1.0%
  • 23-32 points: 1.5%
  • <23 points: 2.0%

The scoring system and performance standards are outlined in more detail here.

Health reform not only changes the health care market for the demand side (e.g., patients, insurers), but also for the supply side (e.g., hospitals, physicians).  In the Medicare setting, a number of initiatives have aimed to pay providers who provide high-quality or low-cost care more money, and pay providers who provide low-quality or high-cost care less money.  CSC provides a nice overview of some of these initiatives.

  • Performance Value-Based Purchasing (VBP) — Offers increased update to diagnosis-related group (DRG) payment rates to hospitals according to demonstration of performance or improvement in designated performance areas relative to performance standards and benchmarks.
  • Shared Savings Program — For groups of providers who form an Accountable Care Organization (ACO), potentially shares a portion of financial savings in caring for Medicare patients if performance standards are met, according to performance rated on a sliding scale against benchmarks.
  • Readmission Reduction Program (RRP) — Decreases annual adjustments to DRG payment rates for hospitals that are in the lowest performance quartile for excess readmissions of Medicare patients with selected discharge diagnoses.
  • HAC Payment Limitation — Decreases annual adjustments to DRG payment rates for hospitals that are in the lowest performance quartile for a designated set of Hospital-Acquired Conditions (HACs).
  • Bundled Payments for Care Improvement Initiative — One of several initiatives of the CMS Innovation Center to give doctors and hospitals new incentives to coordinate care, improve the quality of care and save money for Medicare. Bundle care for a package of services patients receive to treat a specific medical condition during a single hospital stay and/or recovery from that stay. Applicants pick conditions to target and one of four ways to define the extent of pre- and post-hospital care included in the bundled payment.

In short, the answer is no. The CBO released an issue brief examining two types of demonstrations.

  • Disease management and care coordination demonstrations have sought to improve the quality of care of beneficiaries with chronic illnesses and those whose health care is expected to be particularly costly.
  • Value-based payment demonstrations have given health care providers financial incentives to improve the quality and efficiency of care rather than payments based strictly on the volume and intensity of services delivered.

“The evaluations show that most programs have not reduced Medicare spending: In nearly every program involving disease management and care coordination, spending was either unchanged or increased relative to the spending that would have occurred in the absence of the program, when the fees paid to the participating organizations were considered. Programs in which care managers had substantial direct interaction with physicians and significant in-person interaction with patients were more likely to reduce Medicare spending than other programs, but on average even those programs did not achieve enough savings to offset their fees.”

Today, the healthcare economist looks at these programs in more detail.

Disease Management Demonstrations

These demonstrations were made up of 34 programs operated by disease management companies. “The programs used nurses as care managers to educate patients about their chronic illnesses, encourage them to follow self-care regimens, monitor their health, and track whether they received recommended tests and treatments. In most programs, the care managers were not integrated into physicians’ practices, and their contact with patients was primarily by telephone.”

These programs targeted Medicare beneficiaries with specific chronic diseases. Most programs were not tailored to focus on chronically ill beneficiaries who were expected to have the highest cost of care. The results are displayed in the chart:

test

CBO found that the lack of integration into the physician practice and the lack of physical presence made most of these disease management programs not useful.

Value-Based Purchasing Demonstrations

The list below describes the four major VBP demonstration programs and their findings.

  • Physician Group Practice (PGP) Demonstration. 10 large practices were permitted to keep some of the estimated savings if they reduced total Medicare spending for their patients. In the second year of the demonstration, average Medicare spending excluding the bonuses paid to physician groups was about 1 percent below projections; with bonuses included, average
    Medicare spending was just 0.1 percent below projections—about $7 per beneficiary. Results for years 3 and 4 of the PGP demonstration are currently being analyzed.
  • Premier Hospital Quality Incentive Demonstration. 278 hospitals were offered bonuses if their scores on quality-of-care measures were in the top tier of participating hospitals.  This demonstration had no net effect on Medicare spending.
  • Home Health Pay-for-Performance Demonstration. This demonstration allowed 273 home health agencies to keep some of the estimated savings if they reduced total Medicare spending for their patients and met certain criteria regarding quality of care.  Initial results indicate that this demonstration had no net effect on Medicare spending.
  • Medicare Participating Heart Bypass Center Demonstration. Medicare made bundled payments to cover all inpatient hospital and physicians’ services for coronary artery bypass graft surgeries conducted at seven participating hospitals. Bundled payments reduced Medicare’s expenditures for heart bypass surgeries by about 10 percent, and there were no apparent
    adverse effects on patients’ outcomes.

Whereas the first three VBP programs aimed to give providers bonuses for reducing cost and increasing quality, the Heart Bypass Center demonstration relied on bundled payments to align the financial incentives offered to hospitals and physicians. The bundled payments reduced cost without decreasing quality. Of course, measuring quality is difficult and it is possible that the Bypass demonstration did not fully capture all important aspects of quality. Nevertheless, these initial results indicate that bundling may be a more promising cost-saving mechanism than provider bonuses.

In 2015, Medicare will begin implementing a value-based purchasing (VPB) program for physicians.  Initially the program will target only certain physicians and groups of physicians, but by 2017 all physicians is participate in this program.

The VBP program will evaluate physicians along two broad dimensions: quality and cost.  In the final rule:

Section 1848(p) of the Act requires the Secretary to ‘‘establish a payment modifier that provides for differential payment to a physician or a group of physicians’’ under the physician fee schedule ‘‘based upon the quality of care furnished compared to cost *** during a performance period.’’ The provision requires that ‘‘such payment modifier be separate from the geographic adjustment factors’’ established for the physician fee schedule. In addition, section 1848(p)(4)(C) of the Act requires that the value modifier be implemented in a budget-neutral manner.

 

Quality

The current quality measures to be used include:

  1. The measures in the core set of the Physician Quality Reporting System (PQRS);
  2. All measures in the Group Practice Reporting Option (GPRO) of the Physician Quality Reporting System; and
  3. the core measures, alternate core, and 38 additional measures in the Electronic Health Records (EHR) Incentive Program measures.

Cost

The current measures of cost CMS is using are total per capita cost measures and per capita cost measures for beneficiaries with four chronic conditions (COPD; heart failure; coronary artery disease; and diabetes).

By January 2012, however, CMS will choose an episode grouper which can evaluate physicians based on episodes of care. Specifically:

Section 1848(n)(9)(A) of the Act requires us to develop by January 1, 2012, an episode grouper that combines separate, but clinically related items and services into an episode of care for an
individual, as appropriate.

Other Issues

One of the main problems of the physician VBP is attribution of patients to doctors. In managed care organizations, patients are assigned a primary care doctor or gatekeeper who are responsible for the patient’s overall care. In Medicare, the patient can see any willing provider; because the primary care doctor cannot restrict the patient’s choice of care, it is more difficult to hold them responsible for the care. Specifically, Medicare beneficiaries never have to choose a primary care doctor, so identifying the doctor to be ultimately responsible for each patient’s overall care is difficult.

Physicians require additional information to understand why the received the VBP scores they did. For this purpose, CMS will create Physician Feedback Reports, confidential reports providing more detailed information of the underlying factors which produce these scores.

For the VBP modifier in 2015, CMS will use 2013 as the initial performance period 2013. This means that payment adjustments in 2015 will be on care provided 2 years ago. Although evaluating physician performance, allowing for appeals and adjusting payments takes time; two years is a long lead time.

The Medicare billing system is complex.  There an alphabet soup of acronyms, (e.g., RVUs, CPT, HCPCS, GPCI) and each of these affects payments in different ways.  In addition to the standard payment terms, Medicare is also creating additional payment incentives.  These payment incentives fall into three broad categories:

  • Quality reporting
  • e-Prescribing (eRx)
  • Electronic Health Records (EHR)

CMS’s Physician Quality Reporting System (PQRS) allows physicians to report the quality of care their patients receive. Physicians can report PQRS measures through claims, registries, or EHR systems.  To incentivize physician participation in the PQRS, CMS has adopted incentive payments.  In 2012-2014, Physicians who meet the PQRS participation requirements will receive a 0.5 percent payment bonus.  In 2015 through 2017, however, who do not submit a sufficient number of PQRS measures actually will receive a payment reduction.

In addition to the PQRS incentive, beginning 2012, Medicare eligible professionals who are not successful electronic prescribers under the eRx Incentive Program to a payment adjustment. This payment adjustment applies to all of the eligible professional’s Part B-covered professional services under the Medicare Physician Fee Schedule (MPFS). From 2012 through 2014, the payment adjustment will increase with each new reporting period. Accordingly, for 2012, eligible professionals receiving a payment adjustment will be paid 1.0% less than the Medicare Physician Fee Schedule (MPFS) amount for that service. In 2013 and 2014, the payment adjustment increases to 1.5% and 2.0% respectively.

A table summarizing these incentive payments is below.

Year PQRS eRx
Incentive Payment MOC Incentive Sucessful
2011 1.0% 0.5% 1% N/A
2012 0.5% 0.5% 1% -1%
2013 0.5% 0.5% 0.5% -0.5%
2014 0.5% 0.5% N/A -2%
2015 -1.5% N/A N/A N/A
2016 -2.0% N/A N/A N/A
2017 -2.0% N/A N/A N/A

CMS also offers physicians incentive payments to adopt EHR.  Incentive payments can be as high as $18,000 per year or $44,000 over a five year period.

CSC provies a nice overview of some of Medicare’s hospital quality initiatives. These initiatives include a value-based purchasing (VBP) program, reduced reimbursement for excessive hospital readmissions, and reduced reimbursement for hospital-acquired conditions (HAC).  Each of these three broad quality initiatives is described in more detail after the jump.

It is important to note that these quality initiatives are not voluntary and affect hospital payments through adjustments to the base DRG rate. Broadly, measures fall into three categories: i) claims-based, chart-abstracted, and patient satisfaction (i.e., HCAHPS).  Many of these quality measures will be part of the Inpatient Quality Reporting (IQR) program and will included in the Hospital Compare website.

Also, Medicare is implementing these three programs on top of similar programs which include:

  • Non-payment for care to treat specific HACs (see here)
  • A Medicaid program which also will not pay for care to treat HACs (see here)
  • Mandated review by QIOs of hospital readmissions within 31 days to assess standards of care and potentially recommend denial of payment (see here)

Massachusetts’ Medicaid program instituted a pay-for-performance program in 2008.  Did it work?  According to this paper, the answer is no.

MassHealth P4P Background

The MassHealth pay-for-perfrmance P4P program was implemented in 2008.  At first the program was implmented using a P4P structure for pneumonia and pay-for-reporting for surgical infection prevention (SIP) and transitioning to P4P for both conditions in 2009. The program measures and incentivizes hospital quality for a subset of MassHealth [Massachusetts Medicaid program] patients who are enrolled in plans that directly bill MassHealth.

The Measures

For pneumonia:

  • oxygenation assessment,
  • blood culture performed in emergency department before first antibiotic received in hospital,
  • adult smoking cessation advice and counseling, initial antibiotic received within 6 hours of arrival, and
  • appropriate antibiotic selection in immunocompetent patients.

For Surgical Infection Prevention (SIP):

  • prophylactic antibiotic within 1 hour of surgical incision,
  • appropriate antibioticselection for surgical prophylaxis, and
  • prophylactic antibiotic discontinuedwithin 24 hours after surgery end time.

Evaluating Hospital Performance

The MassHealth P4P followed the Hospital VBP Report to Congress. Hospital performance on individual measures is aggregated to create a composite score; this composite score then is used to indicate the share of the bonus paymen that each hospital receives. More information on the Hospital VBP Report to Congress can be found here.

Identification Strategy

“We do not observe the quality of care provided to Medicaid patients in Massachusetts and other states, and instead we observe the quality provided to patients from all payers. Our identification strategy assumes that the financial incentives of the MassHealth program, which are based on quality performance
for only a subset of MassHealth patients, are reflected in the quality of care received by all patients.”

The authors control for:

  • Observed and unobserved hospital characteristics which remain fixed over time (i.e., fixed effects)
  • A secular trend in quality for each hospital (i.e., using a hospital-specific time trend)
  • Hospital case mix measured by a “difficulty index” to identify cases where hospitals choose patients selectively after P4P was implemented
  • In one sensitivity analysis, the authors use propensity scoring, nearest neighbor, one-to-one matching without replacement to create a sample of non-Massachusetts hospitals similar to those in Massachusetts. Hospitals were matched based on ownership, nuber of beds, urban/rural status, share of Medicare patients, and share of Medicaid patients.
  • The authors also test if hospitals with more Medicaid patients are more likely to have a larger increase in quality.

Evaluating Hospital Performance

The authors find that the MassHealth P4P has little effect on quality. “Estimates from our preferred specification, including hospital fixed effects, trends, and the control for measure completeness, indicate small and nonsignificant program effects for pneumonia (−0.67 percentage points, p>.10) and SIP (−0.12 percentage points, p>.10). ” The result could be due to the fact that P4P has, in actuality, no effect on quality. On the other hand, by using hospital-specific time trends, there may be little variation in quality over time to capture quality improvements after the P4P implementation.

At a recent AcademyHealth presentation, Cheryl Damberg discussed her research to design a P4P program for implementation for Integrated Healthcare Association (IHA).  One thing I noticed about the presentation was that smaller provider groups had patients with lower risk scores (i.e., healthier patients).  Is it really the case that small providers treat much healthier patients?

My guess is the answer is not.  An alternative explanation would be that small providers do not have as much time or administrative staff to help them code the patient’s comorbidities in their claims (or even EMR).  If this is the case, it would make it appear that small provider’s patients are healthier when in fact the true differences may be due to differences in the quality of the data the providers report.

Any VBP system would need to take into account these differences when evaluating providers.  Setting a lower standard for small providers, however, would provide a disincentive for small providers to expand into the large provider category, even if this expansion could (potentially) create economies of scale and improve patient care.

The Healthcare Economist has already commented on the impending Medicare implementation of a hospital value-based purchased (VBP) system.  Now, Medicare’s hospital VBP program has garnered the attention of the popular press.  According to the New York Times:

The administration plans to establish ‘Medicare spending per beneficiary’ as a new measure of hospital performance…Hospitals could be held accountable not only for the cost of the care they provide, but also for the cost of services performed by doctors and other health care providers in the 90 days after a Medicare patient leaves the hospital…

In calculating Medicare spending per beneficiary, the administration said, it wants to count costs generated during a hospital stay, the three days before it and the 90 days afterward. This, it said, will encourage hospitals to coordinate care “in an efficient manner over an extended time period…

Medicare will begin computing performance scores in July, for monetary rewards and penalties that start in October 2012.

Do hospitals like the plan? Some do, but many do not.

This plan has drawn fire from hospitals, which say they have little control over services provided after a patient’s discharge — and, in many cases, do not even know about them…Without opposing the change, lawmakers from higher-cost states like Massachusetts and New York say the payment formula needs more work…Kenneth E. Raske, president of the Greater New York Hospital Association, said the formula ‘tends to discriminate against inner-city hospitals with large numbers of immigrant, poor and uninsured patients.’

By contrast, J. Kirk Norris, president of the Iowa Hospital Association, welcomed the new plan. ‘Medicare ought to pay for value,’ he said.

Will Medicare adequately risk adjust provider payments? Can hospitals coordinate post-acute care once their patients leave the hospital? Will additional coordination lead to increased industry consolidation and–in the long-run–increased health care cost? Will hospitals be able to game the system? How will Medicare monitor quality?

I have discussed these issues in series of previous posts on value-based purchasing. Hopefully, Medicare will get it right this time and improve quality while reducing cost. At this point, however, with Medicare Trust Fund set to be exhausted in 2024, reducing cost may be the priority which trumps all others.
