More than 4,900 U.S. hospitals participate in the Hospital Consumer Assessment of Healthcare Providers and Systems Survey (HCAHPS), including 3,529 that received star ratings in the most recent quarterly update. These ratings reflect an effort by the Centers for Medicare & Medicaid Services (CMS) to help consumers make informed choices about their care, putting more decision-making and purchasing power in their hands.
Because star ratings are expected to play an increasing role in helping consumers choose hospitals, it is important to understand these metrics and what hospitals can do to improve their performance.
Toward that end, Ascom created a comprehensive, time series database of hospital HCAHPS performance.
Changes to hospital Star Ratings over time
Leveraging our database, we conducted a year-over-year analysis of star ratings for all participating hospitals, providing insights into how star ratings change over time as well as clues to what it may take to improve performance.
As shown in the table below, our analysis revealed that star ratings tend to be sticky. In our year-over- year comparison across all hospitals, 61 percent of ratings remained unchanged. Overall, only 18 percent of ratings improved over a 12-month period, while 21 percent declined.
Why Star Ratings are slow to change
There are two main reasons that hospitals’ star ratings tended not to change over a 12-month period.
Because the quarterly HCAHPS results include four quarters’ worth of survey data, it can take a while for improvements to show up in the ratings. Even if a hospital achieves significant improvements in its most recent quarter, that quarter’s results are combined with the previous three quarters’ poorer results when they are reported by CMS.
There is also the difficulty of the task at hand. It’s not just a matter of providing excellent patient care – which is difficult enough; it’s also a matter of providing this level of care at the highest level of consistency.
Consistency is the key to improvement
Consistency is important at two levels. The first is across the HCAHPS domains. While HCAHPS monitors several different individual domains such as care transition, cleanliness, etc., they all add up to a total experience across each individual patient’s journey.
Our correlation analysis between all the linear mean scores for all HCAHPS domains found that if a patient’s satisfaction with one domain was high, then satisfaction with all domains tended to be high and vice versa. This in turn drove overall satisfaction with the hospital, and patient likelihood to recommend the hospital to others.
The Department of Health and Human Services (HHS) filed its annual year-end report to Congress at the start of 2019. The 22-page report summarized nationwide trends in health information exchange in 2018, including the adoption of EHRs and other technologies that support electronic access to patient information. The most interesting takeaway has to do with the ever-elusive healthcare interoperability.
According to the report, HHS said it heard from stakeholders about several barriers to interoperable access to health information remain, including technical, financial, trust and business practice barriers. “These barriers impede the movement of health information to where it is needed across the care continuum,” the report said. “In addition, burden arising from quality reporting, documentation, administrative, and billing requirements that prescribe how health IT systems are designed also hamper the innovative usability of health IT.”
To better understand these barriers, HHS said it conducted multiple outreach efforts to engage the clinical community and health IT stakeholders to better understand these barriers. Based on these takeaways, HHS said it plans to support, through its policies, and that the health IT community as a whole can take to accelerate progress: Focus on improving interoperability and upgrading technical capabilities of health IT, so patients can securely access, aggregate, and move their health information using their smartphones (or other devices) and healthcare providers can easily send, receive, and analyze patient data; increase transparency in data sharing practices and strengthen technical capabilities of health IT so payers can access population-level clinical data to promote economic transparency and operational efficiency to lower the cost of care and administrative costs; and prioritize improving health IT and reducing documentation burden, time inefficiencies, and hassle for health care providers, so they can focus on their patients rather than their computers.
Additionally, HHS said it plans to leverage the 21st Century Cures Act to enhance innovation and promote access and use of electronic health information. The Cures Act includes provisions that can: promote the development and use of upgraded health IT capabilities; establish transparent expectations for data sharing, including through open application programming interfaces (APIs); and improve the health IT end user experience, including by reducing administrative burden.
“Patients, healthcare providers, and payers with appropriate access to health information can use modern computing solutions (e.g., machine learning and artificial intelligence) to benefit from the data,” HHS said in its report. “Improved interoperability can strengthen market competition, result in greater quality, safety and value for patients, payers, and the healthcare system generally, and enable patients, healthcare providers, and payers to experience the promised benefits of health IT.”
Interoperability barriers include:
Technical barriers: These limit interoperability through—for example—a lack of standards development, data quality, and patient and health care provider data matching. Addressing these technical barriers by coordinating to establish the technological foundation for standardizing electronic health information and by promoting exchange of that information can considerably remove these barriers.
Financial barriers: These relate to the costs of developing, implementing, and optimizing health IT to meet frequently changing requirements of health care programs. The cost to adjust health IT to meet these requirements can impact innovation and the timeliness of technical upgrades. Specific barriers include the lack of sufficient incentives for sharing information between health care providers, the need for enhanced business models for secondary uses of data, and the current business models for health systems or health care providers that do not adequately focus on improving data quality.
Trust barriers: Legal and business incentives to keep data from moving present challenges. Health information networks and their participants often treat individuals’ electronic health information as an asset that can be restricted to obtain or maintain competitive advantage.
Elsewhere, the Center for Medical Interoperability, located in Nashville, Tenn., is an organization that is working to promote plug-and-play interoperability. The center’s members include LifePoint Hospitals, Northwestern Memorial Healthcare, Hospital Corporation of America, Cedars-Sinai Health System, Hennepin Healthcare System, Ascension Health, Community Health Systems, Scripps Health, and UNC Health Care System.
Its mission is “to achieve plug-and-play interoperability by unifying healthcare organizations to compel change, building a lab to solve shared technical challenges, and pioneering innovative research and development.” The center stressed that the “lack of plug-and-play interoperability can compromise patient safety, impact care quality and outcomes, contribute to clinician fatigue and waste billions of dollars a year.”
More interoperability barriers identified
In a separate study, “Variation in Interoperability Among U.S. Non-federal Acute Care Hospitals in 2017,” showed additional difficulty integrating information into the EHR was the most common reason reported by hospitals for not using health information received electronically from sources outside their health system. Lack of timely information, unusable formats and difficulty finding specific, relevant information also made the list, according to the 2017 American Hospital Association (AHA) Annual Survey, Information Technology Supplement.
Among the explanations health systems provided for rarely or never using patient health information received electronically from providers or sources outside their health system:
Difficult to integrate information in EHR: 55 percent (percentage of hospitals citing this reason)
Information not always available when needed (e.g. timely): 47 percent
Information not presented in a useful format: 31 percent
Information that is specific and relevant is hard to find: 20 percent
Information available and integrated into the EHR but not part of clinicians’ workflow: 16 percent
Hospitals, when asked to explain their primary inability to send information though an electronic exchange, pointed to: Difficulty locating providers’ addresses. The combined reasons, ranked in order regardless of hospital classification (small, rural, CAH or national) include:
Difficult to find providers’ addresses
Exchange partners’ EHR system lacks capability to receive data
Exchange partners we would like to send data to do not have an EHR or other electronic system to receive data
Many recipients of care summaries report that the information is not useful
Cumbersome workflow to send the information from our EHR system
The complexity of state and federal privacy and security regulations makes it difficult for us to determine whether it is permissible to electronically exchange patient health information
Lack the technical capability to electronically send patient health information to outside providers or other sources
The report also details other barriers related to exchanging patient health information, citing the 2017 AHA survey:
Greater challenges exchanging data across different vendor platforms
Paying additional costs to exchange with organizations outside our system
[Need to] develop customized interfaces in order to electronically exchange health information
“Policies aimed at addressing these barriers will be particularly important for improving interoperable exchange in health care,” the report concluded. “The 2015 Edition of the health IT certification criteria includes updated technical requirements that allow for innovation to occur around application programming interfaces (APIs) and interoperability-focused standards such that data are accessible and can be more easily exchanged. The 21st Century Cures Act of 2016 further builds upon this work to improve data sharing by calling for the development of open APIs and a Trusted Exchange Framework and Common Agreement. These efforts, along with many others, should further improvements in interoperability.”
