Evidence-Based CDS Linked to Improved Value-Based Care Performance Scores

When nurses are armed with the latest evidence-based nursing procedures at the point of care and real-time step-by-step guides for clinical decision making at the bedside, Hospital Value-Based Purchasing (VBP) Program scores go up. That was the primary finding of a study undertaken by the Rockburn Institute in partnership with Wolters Kluwer Health, which found that hospitals where nurses used two specific evidence-based Clinical Decision Support (CDS) tools for two years had an average rank that was nearly 25 percent higher than their peers.
The findings are a rare instance where the intervention—in this case Lippincott Procedures and Lippincott Advisor from Wolters Kluwer—can be clearly associated with change in practice and quality improvement. In fact, the study’s findings clearly support the value and use of point-of-care CDS tools in a clinical setting to augment nurses’ substantial knowledge when needed. The results also demonstrate the close relationship between nurse, information, patient and performance improvement, which ultimately leads to improved quality and efficiency.
A VBP Primer
The Centers for Medicare and Medicaid Services (CMS), through its Hospital VBP Program, has incentivized hospitals to improve patient care and minimize costs by structuring its reimbursement system to reward care quality rather than service quantity. To fund the program, CMS reduces each hospital’s base operating payment by up to 2 percent, which hospitals can earn back (along with bonuses) by achieving high VBP performance scores.
In effect, VBP pits hospitals against each other and their own past performance to show achievement and improvement. Performance is currently assessed using four quality domains: 1) Clinical Care, 2) Experience and Coordination of Care, 3) Safety, and 4) Efficiency and Cost Reduction.
Each participating hospital receives an achievement and improvement score for each domain. The higher of the two is selected and weighted accordingly. All domain scores are then summed together to create the VBP Total Performance Score (TPS). This score is then converted into the hospital’s “adjustment factor,” a multiplier CMS applies to a hospital’s base payment covering each patient’s stay during a given time period.
Adjustment factors above 1.0 indicate that a hospital will receive back from CMS their full withholding plus a bonus. Hospitals with an adjustment factor below 1.0 will be assessed a penalty. For example, a hospital with a VBP adjustment factor of 0.9903 would be paid 99.03% of what Medicare usually reimburses for each service. It’s important to note that the VBP program is a mix of withholding repayment and bonus (or penalty) and required by law to be budget neutral.
The Study Methodology
To determine if and to what extent CDS could help hospitals improve performance on key metrics, the Rockburn Institute evaluated data compiled over a three-year period from all U.S.-based hospitals with a CMS Certification Number that participated in the VBP program. From this base of approximately 3,000 hospitals, 41 facilities were identified that utilized both Lippincott Procedures and Lippincott Advisor for the complete 2014 and 2015 calendar years.
The performance of hospitals using the CDS tools—which represented a mix of community-based clinics, hospitals serving large geographic regions and large university-based systems in 20 different states—was compared to the other hospitals that had received VBP scores for 2014 and 2015. Scores of the 41 CDS facilities were then evaluated for 2017 against their previous years’ results.
The Findings
The analysis found that the hospitals with both CDS tools achieved higher TPS than the national median for the corresponding fiscal years (FY2016 and FY2017). Longer use of CDS during the study period was also often associated with higher scores on these measures.
Specifically, the 41 hospitals that used both tools throughout 2014 and 2015 achieved higher performance on important VBP measures assessing quality that can directly affect their Medicare reimbursement payments and their overall bottom line. They also achieved TPS that were higher than the national average, 40.1 compared to 35.6 for FY2017.
In addition, using the rank ordering methodology, the study revealed that the 41 hospitals achieved an average ranking that was approximately 24.5 percent higher in FY2017 than hospitals that did not use both tools in 2014-2015. This includes hospitals that may have used either product, but not both.
Similarly, the average VBP adjustment factors for the 41 hospitals were higher than the national average during FY2015, FY2016, and FY2017. Specifically, they were assigned adjustment factors that averaged 1.002171, 1.003472 and 1.004608 respectively, compared with the national averages of 1.001139, 1.002142, and 1.001845. In fact, the 41 hospitals continued to increase their average VBP adjustment factor even when the national average went down between FY2016 and FY2017.
The VBP Efficiency Domain is scored using Medicare Spending Per Beneficiary (MSPB) and is applied to Medicare costs during the period that spans three days prior to and 30 days after hospitalization. As MSPB is the only measure included in the Efficiency Domain, it represents 25 percent of a hospital’s VBP performance and TPS—and thus has more importance than any other single measure.
The 41 hospitals performed better than average on the Efficiency Domain from Fiscal Years 2015-2017, with average scores of 26.6 compared to 20.1. In addition, they showed positive improvement during the three-year period, while the national average declined.
Analyzing the Findings
The results of the Rockburn-Wolters Kluwer study support the value and use of evidence-based CDS tools in a point-of-care, clinical setting to help clinicians effectively balance patient-centered, high-quality care delivery and cost minimization. This is particularly important for facilities participating in the Hospital VBP program, which rewards the delivery of high-quality patient care over assignment of a high volume of procedures.
Hospitals that armed clinical staff with point-of-care, evidence-based CDS tools over a two-year period achieved a performance edge over the national average on multiple VBP domains and on their overall TPS and adjustment factor. This demonstrates that, given the right informational tools, hospitals can improve their ability to balance cost reduction and a favorable return on investment with positive patient outcomes and a higher quality of care.
The findings also suggest a close relationship between clinicians, their ability to gain access to evidence-based information, and overall hospital performance improvement. For that reason, under VBP, it is incumbent on hospital systems to provide clinical teams with point-of-care tools that are based on the best available evidence. This will optimize both clinical practice and patient outcomes and will in turn optimize reimbursements.
