Personal Health Records: Their Role and Purpose in People’s Lives

1. Personal Health Records:Their Role and Purpose in People’s Lives Barbara M. Wildemuth Kaitlin L. Costello School of Information & Library Science University of North Carolina at Chapel Hill

2. Personal health record: Definition A PHR is “an electronic, lifelong resource of health information needed by individuals to make health decisions. Individuals own and manage the information in the PHR, which comes from healthcare providers and the individual. The PHR is maintained in a secure and private environment, with the individual determining rights of access. The PHR does not replace the legal record of any provider.” (Burrington-Brown et al., 2005)

3. PHR use: Current status • As of 2010, about 10% of Americans use a PHR (Markle Foundation) • 83% of respondents believe they should have access to their medical records, and 79% of patients “think it is a good idea to make health records electronic” (Pyper et al., 2004) • 36% of patients would like to be able to add information to their medical records (Pyper et al., 2004) • 42% of people keep medical records in some form; of those who don’t, 84% believe that they should (Harris Interactive, 2004)

4. PHRs: Current applications

5. Studies on PHR use and perception • Uses of PHRs by patients: • Communication with care providers (Wang et al., 2004) • Viewing laboratory results (Ralston et al., 2007) • Continued use by 37% of patients over 10 months (Denton, 2001) • Benefits of PHRs: • Can better participate in health maintenance (Ross et al., 2005; Harris Interactive, 2004; Markle Foundation, 2003) • Support better communication between patient and provider (Tang et al., 2005; Harris Interactive, 2004) • Would improve patients’ understanding of medical conditions and physician’s instructions (Ross et al., 2005) • Concerns about PHRs: • Privacy and security (Pyper et al., 2004; Harris Interactive, 2004) • Inaccuracy and incompleteness of records (Harris Interactive, 2004; Markle Foundation, 2003)

6. Research questions • What are the purposes for which people might create and maintain electronic PHRs? • What types of data do people want to keep in an electronic PHR? • In what ways do people want to interact with their PHRs? • What concerns do people have about electronic PHRs?

7. Study participants • Parents with young children (n=11) • Amy, Cary, David & Bree, Edouard, Elinor, Ellie, Helen, Kevin, Marge, Monica*, Tony • Adults with chronic illnesses (n=13) • Becky, Jane, Joyce, Kail, Marie, Matt, Megan, Melissa, Mike, Samantha, Sharon, Sonia, Tim • Adults caring for older parents (n=9) • Cathy, Evelyn, Judy, Kim, Margaret, Monica*, Nadia, Sandy, Sharie • Older adults (n=11) • Bel, Deb, Geneva, Herman, Isaac, Jack, Martha, Max, Peter, Philip, Victor & Sarah

8. Semi-structured interviews • How/where PHRs are and should be stored • What information a PHR should contain • PHRs for family members • Who should have access to the PHR • Ways that records can be searched and sorted

9. Results related to the ideal PHR • Purposes for maintaining a PHR • What it will contain • How the contents will be sorted/filtered • Who can read it • Who can write on it • Form of PHR; how and where it will be stored

10. Purpose: Summarize medical history • A particular illness and its treatment • Reports on the history of an illness and all the treatments and medications and what did or didn’t work, from the initial diagnosis to the cure or other end. My mother got diagnosed with rheumatoid arthritis and she saw so many doctors and was on so many drugs that it seemed no one could figure out what the right thing to do was. -- Marie • Medications • Reports on, you know, medication trends. You know, if I took something before or if I start to enter something again that I haven’t done before, if it said ,“Hey, this is new, would you like to keep track of such-and-such?” Side-effects, that would be great, if it popped up and said, “You’re currently taking such-and-such, are you having any side-effects?” Because I forget to put those in. -- Megan

11. Purpose: Analyze trends • Changes in symptoms over time • Especially for ongoing issues, to try to figure out what had been done. If I had a log of when I'd been feeling bad and how often it was, trying to figure out whether or not things had changed. Because for long term issues, I don't keep a log, but then I always wish that I had because it's actually really hard to tell sometimes if I'm getting better or worse. – Tim • Tracking health indicators or test results • I think for my own self, it would be cool to plot out from a ten year period or whatever, things like cholesterol level, the IDL and HDLs. And blood pressure. The kind of things that matter. – Evelyn • Monitoring diet and exercise • I would definitely put my diet and exercise stuff in there, so I can track how that affects the symptoms of my conditions. – Melissa

12. Purpose: Communicate with doctor • To aid in communication • The main thing is to use it as a way of interacting with the doctor so we both keep track of what's happening. That's the no. 1 purpose I see for it. – Kevin • To check record before doctor visit • I would look at it just before a scheduled appointment, so I would know what I was talking about when I went to see the doctor, so I could be more educated when I walked into the room. – Cary • As a reminder for follow-up with doctor • We need to often make appointments and sometimes they won't make them... they can't make them a year in advance or 18 months in advance, so we have to remember when he was there so we can make an appointment for him to go back – Tony • To record what happened during doctor visit • Every time I saw Dr. Smith, what date I've seen him, what we discussed, what medication did he change, anything like that… I would see the patterns of how I see him. – Geneva

13. Purpose: Handle an emergency • When injured • Even if you are in a car accident locally, and you are unconscious, it would be good to be able to plug in to something that would see drug interactions or your past history. I can see security problems with it , but it would be nice. -- Nadia • When traveling • One thing that crosses my mind is that... I want to know about international aspects of this. The records could be accessed by a physician in Belgium? That would be… if I have a heart attack in Belgium, could the physical get my records, previous heart tracing and this kind of stuff? That would be useful. --Edouard

14. Content related to treatment • Medications • My son has asthma and he takes his medicine everyday. We just changed his medicine. He's done so well that we actually stepped back a little bit on his medicine. That would be an important thing if I were to keep better records to know exactly when he stepped back so if there is a change we can look back and know when that occurred. -- Cary • Lab test results • It would be interesting to me to have access to my lab work, so I can compare the labs and see if there is any correlation between a period when I'm feeling bad and what my labs were looking like then, compared to when I'm feeling better. --Samantha • Immunizations • I really want to put in immunizations because I see that as a real problem now. We live longer so we really need to be re-immunized. I travel to foreign countries. So that's really the thing I want to keep the abreast of. --Martha

15. Content related to health status • Family history, including genetic history • I'm interested in genealogy and family history. And my father died two years ago. Before that I was communicating with him about family history. I want to know how my grandparents died and what causes might be important for just my own medical history. -- Edouard • Diet and exercise • I suppose if I were on some regimen of exercise, it could be a way of keeping track of which exercises to do. I’ve done some weightlifting and it's good to vary the exercises you're doing. So perhaps a system like this could give you a reminder of what you need to do each day, sort of keep track of the rotation of things. -- Kevin • Lab test results • I think it probably would be helpful to look at things like blood pressure over time. That’s not really a lab test, but it’s more a maintenance-y kind of measure. -- Jane

16. Sorting the records in the PHR • By date • I would want to sort it by date, so I would be able to see a period of time. -- Joyce • By illness/condition • There was a time that I had headaches. I went to a series of different doctors. I found it is caused by my eye lids -- I had a droopy eye lid… So I want to be able to sort by illness. -- Max • By test • Maybe have lab reports in a folder, maybe even not chronologically, just what they are. Here is the lab results. Here is results for all the physical exams. Here is the result of my cholesterol. --Evelyn • By doctor • Certainly chronologically. Certainly by clinic, by physician. --Max

17. Filtering the records in the PHR • By date/time/season • Ican see a date filter. Although I've been tracking my thyroid for three years, at some point I'll only care about the most recent two years. -- Monica • By illness/condition • It would make sense to link the records by illness or by issue, whatever that might be. For example, when my son had pneumonia, if I could somehow link all those visits and prescriptions for that one illness, I could just view that. --Kevin • By doctor or type of doctor • You could do it based on, for the hospital, all the hospital records, or all his eye doctor records, or all of his cardiologist records... All of his physical therapy things. -- Tony

18. Issues related to PHR access • Those providing care should have access • If I was under the care of a doctor for a particular illness, I would say OK, you can look at everything. Because who knows what might affect it, contribute to it or might be affected by it. –Judy • I mean, I feel like, you know, in my opinion, full, unrestricted access for physicians. I think physicians could do their job better if they had more information at their disposal. --Mike • Patient should have fine-grained control • The best thing would be if the user could control who had access. --Kevin • I would like to be able to pick out what fields that I would like to include there. What things I believe he really doesn't have to know. It is nice to have the control rather than turn over the whole database. -- Evelyn

19. Sharing the PHR across care providers • Benefits • I have several physicians… I would like there to be some easy exchange among them. --Martha • I guess the situation I see as most problematic is when you shift from one physician to another for whatever reason. You know, getting those answers transported takes a lot of time, can be cumbersome… And a lot of times I felt like I was sort of made responsible for making sure that Specialist A knew what Specialist B had done. --Mike • Concerns • Q: What if the record included things that happened outside of the Duke system? G: I don’t know why that doesn’t sound quite right to me. I suppose because it's giving up a whole lot of autonomy to a doctor, that this way I have a choice to do other things outside that system… If I wanted to do something more alternative, which is what the acupuncture is, I would like to feel that I’m doing that without anybody saying, “No, you can’t ,”or “You shouldn’t”. --Geneva

20. Sharing the PHR with family members • Need to share when in caretaker role • I'm kind of, I wouldn't say the care taker, but I'm one of the people who helps take care of my grandfather. He's 80 years old. He has a lot of health problems… It's also important to have duplication of different people knowing, because you never know who will be available to say, “This is what's wrong with my grandfather”. --Sandy • My son has asthma and he takes his medicine everyday. We just changed his medicine… that would be an important thing… to know exactly when he stepped back so if there is a change we can look back and know when that occurred. – Cary • Privacy concerns • The only reason that I would want access to a family member's information is when there is some ongoing health problem that I was involved in their care with. Other than that, no. I don't think that's any of my business. --Bel

21. Adding/editing data in the PHR • Patient • Personal notes • Corrections to physician notes (added) • Less important information (e.g., diet, exercise) • Physician • Anything that would go into the medical record • Pharmacist • Add medication information only; not even see other information • Provide supplementary information about side effects and contra-indications • Family members • Very few responses; mixed opinions

22. PHR location/control (1 of 3) • Personal physician • I would be a little more concerned about security in the doctor's office, because if someone were truly looking for health info, I suspect they would go there instead of to an individual. And I would want my doctor to have backups. --Cary • I’m not sure I want somebody else to be able to read my records. And I don’t know how good my physician’s protective system might or might not be. In fact at the moment – this is completely an aside – I barely have a physician. My physician disappeared! --Isaac • Insurance company • Insurance companies make too many decisions based on what they think, not what your doctor feels is proper for you… I don't think that they have any business in your medical records. –Deb • I have to say I don’t trust insurance companies all that much… They are not out there to help anybody, really. They’re out there to make money. That’s not the attitude I would like a person who has access to all my health records to have. --Geneva

23. PHR location/control (2 of 3) • Home computer • Keeping my records on my home computer would be fine. But again, I don't think we would update it, and we might not back it up. I think it would be easily lost. Now, the home computer systems change so frequently, it would become obsolete. It is very easy to lose records. --David and Bree • I have mine at home. I just had a women that I work with, her son’s apartment was just burglarized and the thieves took their computer stuff. That would concern me. --Joyce • Portable/mobile device • Computers are not perfect – they can be hacked. If people wanted to keep them perfectly safe, they could download data onto a CD, and only the template would be on the computer and you'd back the data up to something else. That's one way of keeping it off a computer that could get stolen, or could be hacked or whatever. --Helen • I would like it to be on a CD or on something, not just sitting on my computer. I am afraid it would get erased. --Martha

24. PHR location/control (3 of 3) • Government agency • I think people are getting skeptical about the government having too much information about us. There are checks and balances, but no. --Cathy • Incidentally, I'm not at all an anti-government person. I would like my taxes to be raised, believe it or not. I think there are lots of things to be done by the government… But health records, no. --Herman • Third party • If it was a program like Quicken, where you could enter your stuff.... I guess the company has your tax info and then it is sent to the government because they get to have it too. And then you also have it on your computer. So it's kind of shared in three places... Something like that could work. – Amy • Q: Would you be willing to have your records on an online website? P: No, no, no. Who would own that site and who would have access to it? --Philip

25. Summary of initial findings • What are the purposes for which people might create and maintain electronic PHRs? • To summarize their medical history, including: • To analyze trends • To communicate with their doctor • To handle an emergency

26. Summary of initial findings • What types of data do people want to keep in an electronic PHR? • Information related to the treatment of particular illnesses or conditions • General information related to their health status

27. Summary of initial findings • In what ways do people want to interact with their PHRs? • View online and get reports • Sort the records • Filter the records

28. Summary of initial findings • What concerns do people have about electronic PHRs? • Who controls access to the records, • For viewing • For adding/editing • Where will the record be maintained

29. Implications • Issues in interface design • Balancing completeness and complexity • Incorporating sorting and filtering features • Issues in access and control • Trusted third-party
