Patient-Centered Outcomes Research
Patient-Centered Outcomes Research (PCOR) helps patients and their caregivers communicate and make informed healthcare decisions, allowing their voices to be heard in assessing healthcare options.
Value of PCOR and Role of PCORI
The Patient-Centered Outcomes Research Institute (PCORI) is the leading funder of patient-centered comparative clinical effectiveness research (CER) in the United States.
PCORI helps people make informed healthcare decisions, and improves healthcare delivery and outcomes, by producing and promoting high-integrity, evidence-based information that comes from research guided by patients, caregivers, and the broader healthcare community.
CER research answers patient-centered questions and helps clinicians address their public health priorities. Patients are integral in the design of PCOR and CER studies. PCOR and CER can be used to identify specific interventions and actions that have been scientifically assessed on whether they effect the desired change.
PCORI implementation projects promote the use of findings from PCORI-funded studies in real-world healthcare and other settings. These projects build toward broad use of evidence to inform healthcare decisions.
Use current, relevant findings from PCORI as a resource for empowering your patients. You can sign up for PCORI updates to get notifications of new research, resources, and funding announcements right to your inbox.

For example, you can learn how a research team empowered the “Marshallese Community in Managing Type 2 Diabetes” project by creating culturally adapted training on type 2 diabetes management.
- Evidence Updates such as “Daily Blood Sugar Tests May Not Be Beneficial for Some Patients”
For people with type 2 diabetes, maintaining their blood sugar at a healthy level is important. But checking their blood sugar every day may not help them manage the condition. This PCORI-funded study found people with type 2 diabetes who don’t use insulin did not benefit from daily self-testing. Study participants who checked their blood sugar each day for a year had the same A1c and quality of life as people who didn’t test daily. An Evidence Update is available that can help clinicians and patients work together to make informed decisions regarding patient care. - Study results that support informed decisions such as “Developing and Testing a Type 2 Diabetes Education Program Adapted for Marshallese Culture ”
Read more about the work that clinicians, patients, and researchers are developing, get resources for you and your patients, and learn how to put the new findings into practice. For example, learn how a research team empowered the Marshallese community in managing type 2 diabetes through creating culturally adapted training. The material incorporates knowledge of patients’ backgrounds, cultures, ethnicities, and belief systems to increase their understanding of health topics. PAs can find patient materials, watch videos, learn more about why culturally adapted materials are important, and how the research team implemented the project on the project page for “Developing and Testing a Type 2 Diabetes Education Program Adapted for Marshallese Culture” at PCORI. - Find study spotlights such as “Including Patient Traits in Benchmarks for Diabetes Care”
In “Including Patient Traits in Benchmarks for Diabetes Care,” you can read more about how creating benchmarks that compare quality of care across clinics can help clinicians recognize performance gaps and improve diabetes care. Professional medical organizations recommend using glycemic target goals based on average glycosylated hemoglobin (HbA1c) levels to guide clinical care. Although these goals serve as a benchmark for the average patient, they do not account for patient-specific clinical, demographic, and socioeconomic factors that may affect treatment response. The research team created online benchmark calculators for doctors and patients to compare quality of care across clinics. Doctors can use the results to compare quality of care and inform treatment decisions for diabetes care.What were the results?
Many traits affected how well patients responded to diabetes treatments, including:- Personal traits, such as age, race, ethnicity, education, and income
- Physical traits, such as blood pressure or HbA1c results before treatment
- Patients’ quality of life, such as mental stress or how much symptoms affect the patient
- How satisfied patients were with their treatment

PCORI has curated all of their resources related to mental and behavioral health to support patients, communities, and clinicians to make informed healthcare choices. You can find many materials such as:
- Evidence Updates such as “Treating Depression in Patients With Kidney Failure Receiving Dialysis”
Depression is common in people who are on dialysis and can affect kidney health, as well as overall well-being. This PCORI-funded study found that patients with depression who received sertraline, compared with patients with depression who received CBT, had modestly better depression scores and improvements in other patient-reported outcomes – but also reported more frequent mild to moderate adverse events. Two Evidence Updates are available for patient and for clinicians to help them work together to make informed decisions regarding patient care. - Study results that supports better informed decisions such as “Testing a Peer-Support Program for Parents of Infants Going Home From the NICU”
In “Testing a Peer-Support Program for Parents of Infants Going Home From the NICU,” the research team tested a peer navigator program to improve parents’ mental health and confidence in caring for their infants. Peer navigators were parents with experience having a child in the NICU. The team compared parents who were in the peer support program with parents who weren’t in the program. In this study, the parent navigator program and care notebook did not improve parental self-efficacy or mental health, or infant health outcomes more than the care notebook alone. - Find study spotlights such as “Comparing Two Telehealth Approaches for Treating Complex Psychiatric Disorders in Primary Care – The SPIRIT Study”
Federally Qualified Health Centers, or FQHCs, are community clinics that provide primary care in rural and other underserved areas. FQHCs often don’t have enough mental health specialists to treat patients with complex mental health conditions, such as patients with both posttraumatic stress disorder and bipolar disorder.In “Comparing Two Telehealth Approaches for Treating Complex Psychiatric Disorders in Primary Care – The SPIRIT Study,” the research team compared two telehealth approaches for patients with complex mental health conditions who received care at rural clinics. Telehealth is a way to provide care to patients remotely using phone or video calls. The two approaches were:- Telepsychiatry collaborative care, or TCC. In TCC, patients met with care managers in person or by phone. Care managers taught patients about their mental health, checked their symptoms, and provided therapy. Care managers also had weekly meetings with off-site mental health doctors to review and adjust patients’ treatment plans. Primary care doctors prescribed all medicines for mental health.
- Telepsychiatry-enhanced referral, or TER. In TER, patients had video calls at their clinic with an off-site therapist or mental health doctor. Remote therapists provided therapy and remote doctors prescribed medicine to patients who needed it. TER required more time from therapists and mental health doctors than TCC.
In both approaches, patients first had a video call with a mental health doctor to develop a treatment plan.
What were the results?
After one year, patients in both TCC and TER reported that their quality of life, mental health symptoms, and side effects had greatly improved. Patients in TCC and TER didn’t differ in reports of:- Quality of life
- Severity of mental health symptoms
- Satisfaction with care
- Access to care
- Medicine side effects
Patients didn’t differ in adherence to their mental health medicines.

In “Comparing Two Ways of Combining Behavioral Health Care and Primary Care for Adults,” an ongoing project, the research team is working with 40 healthcare practices in the United States including family medicine clinics, internal medicine clinics, and community health centers. All of the practices offer basic behavioral-health services at the clinic or nearby (colocation). Half of the practices also receive an intensive program to help them add integrated behavioral health services, including:- Online training about integrated behavioral health for behavioral health providers, doctors, nurses, and staff
- A toolkit to help make integrated behavioral health work at their practice
- A workbook to help the practice staff change their current processes to help integrated behavioral health run smoothly

PCORI has curated all of their resources related to pain care and opioids to support patients, communities, and clinicians to make informed healthcare choices. You can find many materials such as:
- Study results that supports better informed decisions such as “Comparing Ways to Treat Back Pain Using a Stratified Risk Approach”
“Comparing Ways to Treat Back Pain Using a Stratified Risk Approach” aimed to test whether a risk-stratified approach to treatment in primary care settings would result in lower rates of patients with acute back pain developing chronic back pain. To assess chronic pain risk, researchers at the University of Pittsburgh asked patients how they were coping with back pain and assigned them to either low-, medium-, or high-risk groups. Patients who scored high risk were placed into two groups: usual care or usual care plus psychologically informed physical therapy, which also teaches patients coping skills to manage back pain. As reported in EClinical Medicine, among patients at high risk, 50% developed chronic back pain regardless of type of care, while 20% of low-risk and 33% of medium-risk patients developed chronic low back pain.

- Find study spotlights such as “Evaluating a Program to Lower Prescription Opioid Doses for Patients With Chronic Pain”
A network of clinics in Washington State started a program to reduce opioid doses prescribed for patients with chronic pain. The program had two phases:- Dose-lowering. Doctors prescribed lower doses of opioids for many patients with chronic pain using opioids long-term. This phase started in 2007.
- Monitoring. Starting in 2010, clinics increased monitoring of patients taking opioids long-term and created care plans for them. Clinic pharmacies also changed the way patients refilled opioid prescriptions
In “Evaluating a Program to Lower Prescription Opioid Doses for Patients With Chronic Pain,” the research team wanted to learn if the program reduced the risks that go along with long-term opioid use. The study compared patients who received care at clinics with and without the program. Read more about the study today.
What were the results?
Patients who received care at clinics with and without the program had similar:- Rates of opioid overdoses
- Ratings of pain severity
- Rates of injuries and car crashes
During the dose-lowering phase, the rate of opioid overdoses decreased at clinics with the program, but not more than it did for clinics without the program. Read more about the study today.

In “Treating Chronic Pain Using Approaches Adapted for Patients With Limited Reading Skills,” the research team compared two types of group treatment with usual care alone. People who got either pain education or CBT along with usual care had less pain than people who had only usual care. They also reported that pain got in the way of doing everyday things less than it did for those who had only usual care. People experienced these improvements slightly more with CBT than with pain education. There were no differences in depression between the groups.You can find all the additional projects PCORI has related to chronic pain in one place.
PCORI has curated all of their resources on obesity to support patients, communities, and clinicians to make informed healthcare choices. You can find many materials such as:
- Evidence Updates such as “Comparing Two Types of Weight Loss Surgery”
Bariatric surgery can help people with obesity lose weight and improve problems related to obesity, like diabetes. But surgery can also cause harm, and outcomes may vary across different procedures. A PCORI-funded study compared the benefits and harms of the two most common types of bariatric surgery: Roux-en-Y gastric bypass, or gastric bypass, and sleeve gastrectomy, or sleeve surgery. A pair of Evidence Updates is now available that can help clinicians and patients work together to make informed decisions regarding patient care. - Find study spotlights such as “Comparing Ways to Treat People With Obesity in Rural United States”
People living in rural areas are more likely to have obesity than those living in cities, and they are also less likely to have access to weight loss programs. This PCORI-funded study compared three ways to treat obesity in rural populations: regular in-person clinic sessions, in-person group sessions, and phone-based group sessions. In a paper published January 2021 in JAMA, the study reported that people in the in-person group sessions averaged greater weight loss after 24 months than the other two groups.What were the results?
After two years, in all three ways, patients lost weight and had improved physical activity, diet, weight-related quality of life, and sleep quality. Compared with in-person visits that were one-on-one, patients who had in-person group visits- Lost 1.9 more kilograms (4.2 pounds) and a greater percentage of weight
- Had greater decreases in triglycerides, or fat levels, in the blood
- Had greater increases in physical activity
Patients who had in-person visits that were one-on-one and in-person group visits didn’t differ in
- Whether patients lost at least 5 or 10% of their weight
- Blood pressure or cholesterol
- Quality of life, sleep, or stress
- Symptoms of anxiety and depression
Patients who had remote group visits didn’t differ in weight loss or other health outcomes from patients who had in-person group or one-on-one visits.

PCORI has curated all of their resources related to cardiovascular disease to support patients, communities, and clinicians to make informed healthcare choices. You can find many materials such as:
- Evidence Updates such as “Reducing Risk of Stroke in Patients With Atrial Fibrillation”
People with atrial fibrillation (AFib) have a higher risk for stroke compared with people who have a normal heart rhythm. Anticoagulants, lower the risk of stroke but can also cause serious bleeding. A recent review of research found that some newer anticoagulants do better at reducing the risk of stroke, and some also reduce the risk of serious bleeding compared to traditional therapies. Two Evidence Updates are available for patients and for clinicians to help them work together to make informed decisions regarding patient care. - Study results that supports better informed decisions such as “Aspirin Dosing Study Highlights Benefits, Effectiveness for People With Heart Disease”
Whether they took a high or low dose of aspirin, people with cardiovascular disease who took aspirin to lower their chances of having a heart attack or stroke experienced similar health benefits according to findings from the PCORI-funded ADAPTABLE Study, the largest aspirin dosing trial conducted in routine care and clinical settings. The results were presented at ACC.21, the American College of Cardiology’s 70th Annual Scientific Session, and simultaneously published in the New England Journal of Medicine. - Find study spotlights such as “Comparing the Effectiveness of Home, Clinic, and Kiosk Blood Pressure Checks for Diagnosing High Blood Pressure – The BP-CHECK Study”
In “Comparing the Effectiveness of Home, Clinic, and Kiosk Blood Pressure Checks for Diagnosing High Blood Pressure – The BP-CHECK Study,” the research team wanted to learn if other methods to check blood pressure worked as well as the 24-hour monitor to diagnose high blood pressure. The team compared the 24-hour monitor with three methods:- Clinic: Patients returned to the clinic once and staff checked their blood pressure
- Home: For five days, patients took their blood pressure at home, twice in the morning and twice at night
- Kiosk: For three days, patients took their blood pressure three times, a minute apart, at a kiosk in a clinic or pharmacy
The research team also looked at patient health outcomes after six months.
What were the results?
- Overall, the home method had the best results
- The home and kiosk methods had more accurate readings than the clinic method
- The clinic method missed high blood pressure more than half of the time
- At home, more patients checked their blood pressure as planned than at the clinic or kiosk
- Patients preferred checking their blood pressure at home to the clinic or kiosk
After six months, across the three methods, patients had lower blood pressure. Patients didn’t differ in how much their blood pressure went down, changes in their physical health, or whether they made lifestyle changes like eating less salt.
Among patients with high blood pressure according to the 24-hour monitor, only 40% had the diagnosis recorded in their health record six months later.
