Healthwise is a nonprofit organization founded in 1975 with the mission to help people make better health decisions. More than 100 million times a year people like you use Healthwise® information to take an active role in their health.
The best formula for making health decisions is to combine the most reliable medical facts with your personal feelings. Put more simply: Medical Information + Your Information = Better Health Decisions.
Your decisions influence your overall well-being as well as the quality and cost of your care. By taking an active role in your health, you are likely to be happier with the care you receive and the results you achieve.
Read these Healthwise stories to see how Healthwise helps people make better health decisions.
Patricia used the Healthwise Knowledgebase to save her own life.
Patricia had just finished her Saturday-morning chores when her lungs began burning. She was sweating and had some numbness in her arms. She drew a bath thinking, "I must be having a panic attack—I'll be all right if I can just relax."
A few hours later, the 42-year-old still felt like she had "an elephant sitting on my chest." Patricia canceled her usual horse-riding lesson and took a nap instead. When she awoke, she felt even worse.
"Then I thought: Check [the Healthwise® Knowledgebase on] the Internet," says Patricia. "I had almost every heart attack symptom described in the Healthwise® Knowledgebase. I knew I had to get to the hospital right away!"
Hospital tests confirmed that Patricia had indeed had a heart attack, and the following Tuesday she had triple-bypass heart surgery. Today, Patricia is back in the saddle, riding horses and enjoying life.
Count on Carolyn Brzezicki—Healthwise clinical specialist and writer, mom, sister, friend, and registered nurse.
"Stories like Patricia's inspire our work every day," says Carolyn Brzezicki. "Each of us at Healthwise thinks about our own stories of how we've turned to our information to help our families, friends, and ourselves make better decisions."
Carolyn, a Healthwise clinical specialist, writer, and content developer, focuses on helping people live better with diabetes. She also reviews the studies, medical literature, and guidelines to assess how new findings in diabetes may affect the content.
Living within just a few miles of her extended family, Carolyn is able to be there for them when they need her—when they're feeling great or not so great. Just like you, she looks for information that's easy to use and understand for her and her family.
Her volunteer work in a diabetes-nutrition center, with hospice, and as a facilitator for a bereavement support group reminds her how confusing medical issues can be. So when she's at work, she always thinks about what's most important for people to know and how it should be explained.
"Because I'm a registered nurse, family and friends call me with questions about a medical test, a new medicine, or what to do about an issue. I always go straight to the Healthwise Knowledgebase," says Carolyn. "Over the years, Healthwise has helped me in so many ways. I'm so proud of our work and how it makes a real difference in people's lives."

Associate Medical Directors:
The Healthwise Medical Review Board also includes health professionals and medical specialists who review Healthwise content from a specialist's point of view. Their credentials include board certification, licensure, and/or registration; academic appointments at leading medical schools; involvement in research; and publication in peer-reviewed journals and medical textbooks. Most important, they share the Healthwise commitment to empowering patients with reliable health information and building strong patient-provider relationships. This encourages partnerships in the decision-making process. With input from these specialists, and with oversight by one of the Medical Directors or Medical Editors, Healthwise medical writers develop health information based on scientific evidence and current clinical practice.
Before approving reviewers, Healthwise verifies that they have current licenses, registrations, and certifications with state or national agencies. We also verify with bodies that certify in specialty areas, if appropriate. The reviewers must be in good standing with these organizations during the time they review Healthwise content. We check this standing at least every 3 years. In addition, reviewers agree to notify Healthwise immediately if the status of their licenses, registrations, or certifications changes.

The field of medicine changes constantly. Each day headlines reveal new ways to diagnose, treat, or prevent health problems. Through a comprehensive topic development process, the Healthwise® Knowledgebase content is regularly updated to keep pace with the changes in medicine and medical practice.
See What's New in the Healthwise® Knowledgebase for the current release.
Healthwise develops content through the collaborative efforts of content and medical teams using a comprehensive research and review process.
The Healthwise content team includes full-time professional medical researchers, writers, and editors who have extensive experience in scientific research and medical writing. They work closely with members of the Healthwise medical team, including the chief medical officer, the medical director, the associate medical directors, and the Healthwise Medical Review Board.
The Healthwise Medical Review Board includes more than 220 health professionals and medical specialists who review Healthwise content from a specialist's point of view. Their credentials include board certification, licensure/registration and/or certification, academic appointments at leading medical schools, involvement in research, and publication in peer-reviewed journals and medical textbooks. Most important, they share the Healthwise commitment to empowering patients with reliable health information and building strong patient-provider relationships.
Healthwise content starts with evidence-based information. Content team members are experts at presenting balanced, unbiased perspectives without influence from commercial interests. Our Conflict of Interest policy enforces our editorial integrity: "All Healthwise personnel should avoid situations where their personal interests could conflict, or reasonably appear to conflict, with the interests of Healthwise. In this regard, personnel must avoid any outside financial interest that might influence, or appear to influence, their corporate decisions or actions."
There are four primary steps in the development process: planning, research, writing, and review.
Healthwise selects new topics on the basis of several criteria, including requests from consumers and organizations using the Healthwise® Knowledgebase, prevalence of the condition, and the potential of shared decision-making for consumers who have the condition.
Healthwise updates topics when warranted by changes in medical practice. The content and medical teams continually review medical news sources and journals so they can quickly identify changes that affect the practice of medicine. When important changes occur, we update topics and include them in the next quarterly release of the Healthwise® Knowledgebase. In addition, Healthwise reviews and updates topics on a regular basis.
Organizations and people using the Healthwise® Knowledgebase may suggest changes or additions to topics. Healthwise considers these recommendations during the topic development process and includes them in our updates if they meet our standard criteria and pass the medical review process. If a suggested change applies only to a particular sponsoring organization's readers, and if it passes medical review, then we may make the change for that organization's customized version of the Healthwise® Knowledgebase. Any change to the Healthwise® Knowledgebase must first pass medical review.
The last revised date is at the bottom of every topic page and in the credits section of each topic.
The Healthwise® Knowledgebase contains thousands of unique references to help readers find more information on topics. Our processes and policies ensure that entry points of content give readers reasonable access to references. We include citations that:
Also, for all self-assessment or risk analysis tools in the Healthwise® Knowledgebase, we provide information that describes the source of the tool, the scientific basis for the tool, how the tool is maintained on the website, the evaluation process, and the last revised date.
Cerner Multum, Inc., Drug Reference (not included in all systems)
The drug reference included in the Healthwise® Knowledgebase is provided by Cerner Multum, Inc., of Denver, Colorado.
Multum updates daily. New information is incorporated into a database as soon as it appears in the literature or in product labeling. Doctors and pharmacists review the new information and make any necessary changes. Multum conducts weekly Current Content searches on all of its drugs, and it surveys all key periodicals. All leaflets are reviewed by one or more practicing clinical specialists. Healthwise receives monthly updates from Multum. The updates are included in the quarterly releases of the Healthwise® Knowledgebase.
Conflict of Interest Policy: Multum's content is authored by full-time associates with no affiliations with drug companies. Consultants who work with the information in other capacities are required to have no conflicts of interest.
The date of the last update is at the end of each topic.
National Cancer Institute (NCI) Topics
NCI Physician Data Query (PDQ®) topics in the Healthwise® Knowledgebase are provided by the National Cancer Institute, National Institutes of Health, Public Health Service, Department of Health and Human Services.
All PDQ cancer information summaries are peer-reviewed and updated monthly by six editorial boards of oncology specialists in adult treatment, pediatric treatment, supportive care, complementary and alternative medicine, screening, prevention, and cancer genetics. They review current literature from more than 70 biomedical journals, evaluate its relevance, and synthesize it into concise, clear summaries. Healthwise receives monthly updates from the National Cancer Institute. The updates are included in the quarterly releases of the Healthwise® Knowledgebase.
Conflict of Interest Policy: PDQ Editorial Board members are selected by the editor-in-chief of each board. Potential biases or conflicts of interest are discussed as part of the selection process.
The date of the last update is at the end of each topic.
Headquartered in Portland, Oregon, Healthnotes, Inc., dba AISLE7 is the premier provider of reliable, easy-to-use health, food, and lifestyle information.
Each year AISLE7 reviews tens of thousands of articles and more than 600 medical and scientific journals to ensure that the content stays current, factual, and balanced. Citations identify the source, the authors, and where and when the information was first published. The AISLE7 editorial team includes medical doctors, pharmacists, chiropractors, naturopaths, and dietitians. The Medical Advisory Board includes medical doctors and experts affiliated with leading medical schools, such as the Robert Wood Johnson Medical School.
