Could your phone be used for more than games?

Nowadays, it seems as if everyone has a cell phone – from kids to our grandparents, they are commonplace.  So why not design an application for the phone that could help improve our health? There are fitness tracking apps and calorie counting apps that are designed to help develop healthy lifestyles, but some suggest using text messages as forms of encouragement.1 One research study tested out the power of a text message in helping people become healthier over a period of six months.256px-Texting_closeup

Researchers from Sydney, Australia studied the effectiveness of text messaging on health in patients with coronary heart disease, a cardiovascular disease where plaque builds up in the arteries slowing the flow of blood to the heart.2,3 One group of patients received a typical intervention such as modifying diet and exercise at the suggestion of their doctor.3 The other group received four text messages each week providing advice, encouragement, and support for lifestyle changes. Text messages that the participants received were selected from a bank catered to the participant’s chronic condition. Participants who were smokers received a message similar to: “Try identifying triggers that make you want a cigarette and plan to avoid them.” Those who were trying a modified dietary approach received messages such as: “Try avoiding adding salt
to your foods by using other spices or herbs.” Others told to increase physical activity received messages like: “Don’t forget physical activity is good for you! It reduces your risk of diabetes, heart attack, stroke, and their complications.” Investigators also sent texts containing information about the cardiovascular system, for example, “Studies show that stress…can increase the risk of heart disease. Please talk to a health professional if you need help.”

The primary outcome of the study was to determine the text messaging effect on cholesterol levels. After six months, the participants who partook in the text messaging intervention had an average LDL cholesterol level of 79 mg/dL which was lower than the typical intervention group who had an average of 84 mg/dL.3 The study also monitored blood pressure, body mass index (BMI), active smokers, and physical activity levels.4 These were all positively affected by the intervention – average blood pressure for the text message intervention group was 128/81 vs 136/84 for control, BMI was lower at 29 vs 30.3, and more physical activity was completed at 936.1 minutes per week compared to 642.7 minutes per week. The study also started off with 184 smokers in the text message intervention group and ended with only 88 people still smoking. Since cardiovascular disease can be managed by lifestyle changes (diet, smoking, physical activity), it is significant that the text messages focused on those areas and help explain why these results were observed.2 One limitation to the study is the small scale, which may not allow representation of the full effect of clinical outcomes. This study was conducted through a hospital facility so it is not known how generalizable this will be to the overall population. Additionally, the messages were only sent in English excluding non-English speakers, the final results were recorded through self-reporting, cost-effectiveness of the intervention was not studied, and the study was not completely blinded.

Similar ideas have been popping up in other places in healthcare. Medicaid uses this system to give more individualized attention to their patients.5 They do this by sending appointment reminders, medication reminders, and also educational material that relates to them specifically.5 Also a study has been done with patients that have had a stroke in which the text messages were sent to remind them to take their medications, dietary and lifestyle changes, and to be in contact with a health care provider.6 This study increased appointment and medication adherence by 40%.5

Data from the research study above shows that text messaging could help to improve your health, and almost everyone has a phone so your motivation comes straight to your fingertips. If your doctor recommends you to be a part of a program like this then I suggest you strongly consider becoming a participant. If you don’t think a typical intervention approach is going to benefit your health, using this text message system could help to improve your health on your own time. It is great that they send little reminders to help motivate and remind you why it is important to follow through. Participating in something similar to this would be beneficial to improve your health as a whole. With today’s technology, this will likely become a bigger thing in the near future. Would you be willing to try using text messages as encouragement or as reminders? I know I would, everyone needs a little bit of motivation to get the ball rolling with whatever you are battling.

    40% increase in appointment and medication adherence is a remarkable feat. As a future pharmacist, I would love to see this kind of text-messaging service be easily available for my patients. It would be even better if patients could subscribe to this service based on their medications/conditions at the click of a button.

  2. Lia G Hickinbotham Says:

    This is fantastic! It would be great if there was an app that could be downloaded for reminders as well as when to take medications, especially is a patient is on multiple medications. It seems like it might increase adherence as well as overall health.

  3. Aaron J Oliver Says:

    As a future pharmacist, I would want all pharmacies have this as an option to increase medication adherence. Since pharmacies now offer the text message service letting patients know that their medication is ready, they should have the option to improve medication adherence on their phone as well.

  4. Micah Bernard Says:

    This is a really cool way to help people manage their health! I agree that it would be a really good idea to have an app that reminds people to take their meds. It would be cool if they could select the drugs they were taking and how frequently, and then the app would provide reminder alerts as well as information about the drugs for the patient.

  5. Monica Saad Says:

    This is really interesting! I wonder if they would try something like this in the United States and how well the results would turn out! I know when I have an app that gives me notifications every day I tend to ignore them after a while, with the busy lifestyle of Americans I really wonder if something like this can really improve Americans health in this way! Very cool if it would work though!

  6. Maame Debrah-Pinamang Says:

    I really like that the study findings were all positive. Would it be possible to also add the family members and people close to the study participants to the texting list in order to improve the compliance? I think that adding more people to improve the network of support will make people feel more confident and be able to adhere to their goals better.

  7. James Baffoe Says:

    That is an interesting article. I think it will be awesome if text messages are incorporated in our duties as pharmacists. Considering how our generation is on text messaging, it help produce a reduce a lot of medical conditions and patient non-compliance to medication. Not only at our job places, but we as individual can also share this “cool app” with our friends and try to stay fit. Would you recommend that the messaging be anonymous?

  8. Tori Bumgardner Says:

    This is so interesting! I like that pharmacies now will text people when their prescriptions are ready and adherence is likely improved because of that. I think this would be a great program to implement for different clinical services in pharmacies also. I know we have a smoking cessation program and if we could offer this to help people quit, I think patients would be much more encouraged as they make the change. I would love to see this used in retail pharmacy!

  9. Jasmine Gunti Says:

    Since this is as effective as has been shown I wonder why it hasn’t been acknowledged and implemented on a large scale. But since this study was done on a small scale it should to be researched more in order to see if it will be generalizable. Furthermore, do these results change based on the age of the patients? It would be good to investigate this more as well.
