Population & Public Health

Public health focuses on protecting and improving health at a population level rather than one person at a time.

The Affordable Care Act (ACA) — which rewards value and care coordination instead of volume and care duplication — requires clinicians to manage this type of patient care at a practice level. This is called practice-based population health.

If you want to improve a population's health, you must be able to measure it. Programs such as the Centers for Medicare & Medicaid Services' (CMS) Quality Payment Program (QPP) identify national focus areas and require the use of electronic clinical quality measures (eCQMs).

Public health agencies also require electronic reporting, because it improves the timeliness and accuracy of the data they needed to identify disease outbreaks and to track disease trends over time.

“Care management” is defined as a set of activities intended to help patients and their caregivers manage medical and behavioral conditions. Care-management objectives are designed to:

• Improve patients’ functional health status
• Enhance care coordination
• Eliminate service duplication
• Reduce the need for expensive medical services

Care management occurs at various levels of the healthcare system, including the population level, the practice or panel level, and the individual patient level. Care-management programs often focus on the challenges presented by patients with chronic conditions, such as heart disease, diabetes, or asthma.

Population health focuses on improving health outcomes for large groups of people by identifying and monitoring individual patients within those groups.

Population health management (PHM) tools help clinicians aggregate and analyze data to create a comprehensive, actionable clinical picture of each patient. With the information generated by these tools, clinicians can track and improve clinical outcomes — and lower healthcare costs.

All states and territories require clinicians to report specific diseases and conditions to public health agencies through various public health surveillance and information systems. Many of these systems are digital and are connected to electronic health records (EHRs). They include:

• Electronic lab reporting, which automatically reports laboratory findings from commercial, public health, hospital, and other labs to state and local public health departments.¹
• Syndromic surveillance reporting, through which ambulatory care providers, hospitals, and urgent care centers send symptomatic data to public health agencies, possibly resulting in early detection of potential public health events.
• Immunization information systems (IIS), which automatically record immunization information from the EHR and merge this information into one reliable source. Clinicians can also receive immunization forecasts and histories from the IIS.
• Electronic case reporting, which automatically sends information from an EHR about a reportable condition to a public health agency for review and action.²
• Public health registries (e.g., cancer, death/birth, newborn screening, trauma), which are collections of specific types of information and vary by local and state jurisdiction.

Clinicians use EHR and health information exchange functions for required reporting. Public health agencies depend upon receiving data from clinicians through these systems. This helps public health agencies measure the prevalence and incidence of diseases, maintain high immunization coverage rates, manage outbreak investigations, and plan for and respond to public health emergencies.

What is a patient registry?

With a clinical data registry, or patient registry, information is uniformly collected. This information helps evaluate specified outcomes for a patient population that is defined by a certain disease, condition, or exposure — such as hepatitis C, fibromyalgia, or thalidomide.

Use registries to:

• Describe the natural history of disease
• Determine the clinical effectiveness of healthcare products and services
• Determine the cost-effectiveness of healthcare products and services
• Measure or monitor safety and harm
• Measure quality of care

A patient registry can help clinicians improve patient care by addressing a predetermined scientific or clinical need. For example:

• A prosthetic-joints registry can help you determine the failure rates of specific product types or track the functional outcomes of various postoperative therapies
• A vaccinations registry can help you judge the success of immunization efforts in your area and identify challenges related to those efforts

What are the types of patient registries?

The Centers for Medicare & Medicaid Services (CMS) recognizes 2 types of patient registries: qualified clinical data registries (QCDRs) and clinical data registries (CDRs).

It’s important to understand the distinctions between these registries:

• Clinicians use QCDRs to collect and submit Physician Quality Reporting System (PQRS) and/or Quality Payment Program (QPP) data for their practice.
• CDRs offer limited reporting value. They’re used only to report some public health data for QPP.

You can use QCDR information for many purposes beyond QPP. For example, you can use it for:

• Clinical research
• State medical licensing
• Supporting American Board of Medical Specialties (ABMS) Maintenance of Certification Part IV

Note: This playbook provides information for QCDRs only.

Who runs patient registries?

Groups with an interest in clinical outcomes can run a patient data registry. The following clinical professional societies have run patient data registries for years:

• American Academy of Pediatrics
• American College of Chest Physicians
• American College of Surgeons
• The Society of Thoracic Surgeons

Initially, data collection for patient registries involved manual chart abstraction. Today, widespread electronic health record (EHR) use makes greater data collection and analysis possible. The result? A dramatic improvement in the ability to understand and monitor quality of care across practices and patients.

How can my practice or group start using a qualified clinical data registry?

The first step is to understand your QCDR options. Start by asking colleagues in your specialty about using a QCDR. Their opinions may help you decide.

Specialty societies also serve as valuable resources. Contact any associated with your practice, such as:

• The American Academy of Family Physicians (AAFP)
• The American College of Surgeons (ACS)
• The American Academy of Ophthalmology (AAO)

What do we do after we select a registry?

Once you select a QCDR, you must complete the application process. You’re not limited to one registry, but most practices participate in only one. During the application process, you will verify your certified EHR system and complete business associate agreements (BAAs).

What does it mean to “map” EHR data?

Your EHR must be configured to provide the correct data — in the right format — to the QCDR. “Mapping” refers to matching specific elements of your EHR data to the corresponding elements in the QCDR files. After you map your EHR data, a practice scorecard shows which measures your current EHR data can accommodate. Your scorecard may list “unmapped” measures. That means that in its current configuration, your EHR can’t supply complete data to report those specific measures. Sometimes adjustments to your EHR, or to practice workflows, can turn unmapped measures into mapped measures.

How do we select measures?

Select which practice measures you will report for QPP. Base this decision on your:

• Practice scorecard
• Quality goals
• EHR data

Choose any measures your practice will use for other reporting, such as medical licensing or ABMS certification.

How do we test data submission?

Your QCDR organization will show your practice how to test data submission and how to receive registry reports based on your performance. Make sure your clinical staff understands what activities and services affect the practice performance score.

How can my practice set goals to improve?

Practices participate in a QCDR to better understand the clinical care they provide to patients with similar conditions. Reporting your performance on QCDR measures is just the first step to improve overall quality of care. The next step involves setting goals for improvement — the entire staff should identify actions they can take to improve performance. Regularly review the QCDR reports and measure your own improvement. This will set your practice on the road to better patient outcomes.
