A Vital Change

Google recently announced a project in which they plan to develop contact lenses that measure a person’s blood glucose level. The project is very much in the early stages of development but it indicates the potential for furthering involvement of technology in healthcare. It is imperative that the healthcare industry supports technological innovations such as this that will improve patient care. Technology must be viewed in the same way as medication in how beneficial it can be to global health.

Google describes the project as a potential game changer for diabetes treatment. The function of the contact lens is to measure glucose levels in tears, thereby making it easier for diabetes patients to determine their blood glucose level. At the moment, a patient must draw his or her blood which can be a difficult and painful process. What ends up happening is that patients fail to regularly check their blood as often as they should and develop further complications as a result. How the data from the lens is made known to the patient is not currently established. Some have suggested a series of blinking lights in the lens that notify the wearer when it is time to take insulin. Another approach is to somehow transmit the data to the user’s smartphone where it is displayed in an application and stored on a secure Google server. In the latter solution it would also be possible to send this stored information to the patient’s physician, providing them with updates on the patient’s progress and insulin usage. A cutting-edge solution to treat diabetes more effectively is vital considering it is one of the fastest growing diseases in the world.

In this modern age of technology and rapid development of new and exciting products that better quality of life the healthcare industry must be more open and supportive of innovation in patient care. Not to say that it is currently averse to the prospect but there exists a lot of red tape and inefficiencies that slow progress. The industry must be willing to adapt as quickly as the rest of the economy in order to realize vital improvements that will help patients today. The laggard mentality and outdated ideals prevalent in the healthcare system must adapt to the current culture of innovation and ubiquitous use of high-tech devices. This will ensure projects such as the Google contact lenses become tangible products.

Can Telehealth and Integrative Medicine Coexist?

Telehealth advocates the use of electronic services to support patient care, education, and monitoring. Proponents of telehealth acclaim its potential to reduce healthcare costs and to increase patient satisfaction. Implementing telehealth, however, would require deconstructing the traditional healthcare encounter. Patients and physicians would have to redefine their expectations for one another, and some argue that telehealth belittles the patient-physician relationship.

Nevertheless, there are clear advantages for telehealth. Telehealth can serve as a means of supporting traditional healthcare. When distance separates participants, patients can use electronics to directly contact their physicians. They can receive direct clinical service miles away from the doctor’s office via virtual visits. If the patient’s health records, medical images, and medication lists are already compiled online, such virtual visits can serve as a timely and efficient way to improve patient care.

Additionally, telehealth allows the early detection of irregular or unfavorable body rhythms. For instance, early detection of irregular heart and brain rhythms could prevent potential heart attacks and seizures. In this respect, telehealth plays a role in preventive medicine and contributes to better health outcomes.

Schwamm (2014) gave an example that cellphone cameras could be used to photograph rashes and skin lesions. This would allow dermatologists to diagnose and treat their patients without having to physically meet. While this form of treatment is fast and efficient, it seems to be in stark contrast with integrative medicine.

Growing in favor since the 1990s, integrative medicine emphasizes a holistic approach to medicine with a focus on health and the physician-patient relationship. With this method of telehealth, the physician-patient relationship is almost nonexistent, and patients are reduced to their skin problems. Furthermore, diagnosis via photograph is hardly holistic; rashes and skin lesions may be signs of a multitude of health problems. It is unlikely that only the dermis is affected, and it would be erroneous to assume that the organ systems of the body work independently.

In Engel (1977)’s seminal article, he claimed the need for a new medical model—namely, the biopsychosocial model. This model posits that biological, psychological, and social factors all play a significant role in the context of disease and illness. Integrative medicine relies on this model because it focuses on the whole body. Therefore, it seems to be opponent to this localized method of diagnosis.

While telehealth has its greatest benefits in early detection, it still has some outstanding limitations. In accordance with the biopsychosocial model, the physician also plays a role in helping the patient cope with stress and vulnerability. On a standardized stress scale, finding out that you are HIV+ scores a 99/100. Given current technological advances, it is possible to get tested for HIV without ever having to actually see a doctor; however, this is a questionable idea. Beyond biomedical treatment, the physician also provides intimate psychological and social support.

Currently, telehealth and integrative medicine can coexist; however, telehealth has its limitations. While it should complement and add value to existing medical care, it should not substitute healthcare completely.

Through the Looking Google Glass

As I was scanning my twitter feed this last week I came across an article discussing one of Google’s newest technology accessories, Google Glass. Google glass is essentially a lightweight pair of eyeglasses that works like a headset equipped with camera, GPS, Bluetooth, microphone, and viewfinder. This technology allows the wearer to connect to smartphones, allowing them to search for and access information online and to use the camera, GPS, etc. all hands-free.

Google Glass: What It Does

With all this information less than a click away and viewable without having to carry a physical device I wondered, what possibilities could this technology have in the world of medicine?

I decided to look at how Google Glass was currently being used in the medical field. I found that this technology provides a means to change the ways the doctors work and communicate both with each other and with patients.

In class we’ve discussed how the internet has come to change how information is spread throughout the medical community, from simple avenues like the increased access to information to more creative paths like the live tweeting of surgeries for the public to access. Technologies like Google Glass make these information sharing “innovations” of today look small in comparison.

A perfect example of this can be seen in an article that discusses a surgery performed by Dr. Pedro Guillen earlier this year. Dr. Guillen was able to perform a highly complex surgery while wearing Google Glass, allowing the surgery to be streamed around the world in real-time. This feature allowed him to serve as an interactive teaching tool to university students and physicians all over the world, opening non-traditional avenues to improve medical education around the globe. The technology, as reviewed by Guillen, also revolutionized the way he performed surgery. The split-screen display allowed him to maximize access to valuable information such as images of the knee, notes, or past surgery videos without having to lift his eyes from the table. While all of these features were impressive one that stood out the most was in the off chance that an error occurred, Dr. Guillen possessed the ability to rewind the tape to review the surgery while standing at the table. This feature can serve to drastically change the way we approach and view medical error in the future.

I also found an account of how Google Glass is working to improve doctor-patient interaction. One company, IOS Health Systems, has developed a native EHR app that can be used with Google Glass. This means that doctors could access patient information such as medical history, vitals, etc. and display it into the heads-up display while talking to the patient. This opens the possibility for doctors to reduce reference to a stationary screen and engage in more direct conversation with the patient, working to improve the doctor-patient interaction.

As I reviewed the literature I marveled at the possible impacts that technology like Google Glass could have on the practice of medicine and considered the role that Google Glass could play in our design setting. In the cardiovascular ICU physicians are required to both consolidate and communicate vast quantities of data into a simple and informative patient narrative and plan of care. In the current system often hand copy detailed data from the patient EHR onto sheets of paper. This practice, while necessary within the system, has created a sort of presentation “crutch,” where fellows will focus and rely on the data that they have spent so much time collecting rather than giving a cohesive patient narrative. Technology like Google Glass can work to eliminate this crutch. By allowing for the information to be readily available and accessible, physicians can focus more on preparing a patient narrative and care plan for presentation during rounds.

While Google Glass offers many positive aspects for the world of medicine it also holds many cautionary aspects. With the adoption of any new technology there come many unanswered questions. How will the ability to stream in real-time at any moment change privacy? Will the knowledge that your doctor is viewing information that you cant see change the way that doctors and patients interact? The positive impacts that utilizing revolutionary technology in medicine can have are great, but as always we must move carefully as we move towards the future.

There Are No Dumb Questions

“There are no dumb questions.” We’ve all heard this before, and as a result, we ask questions for all sorts of reasons. We ask questions because we want to know the answer or because we want to prompt someone else to get to the answer. We ask questions to impress our professors or classmates, to stand alone rhetorically, and to fill awkward silences. We ask questions constantly to other people, to anyone who’s listening, and even to ourselves (don’t pretend you don’t talk to yourself too).

So, why is it that we suddenly clam up in front of our doctors?

Many patients suffer from “white-coat silence,” or “a reluctance to vocalize questions to physicians.” At first this might sound ridiculous. Isn’t that your doctor’s job? To be the medical expert who answers your questions? Why wouldn’t you talk to him/her? While for many people this might seem obvious, for others, the doctor’s office is a strange, scary place where it’s a lot safer to just listen and let the doctor tell you what to do.

However, communication is key to successful patient-doctor interactions. In fact, a study found that the most powerful predictor of positive physician communication is good patient communication, which—surprise, surprise—includes the tendency of patients to ask questions. By asking a question, patients catalyze a cycle of patient-doctor communication in which they provide an opportunity for physicians to share information and give support. Not only does this increase a patient’s knowledge about their own health, but it also makes them feel more comfortable in the clinical setting, making for a better patient-doctor relationship.

So, why don’t patients talk to their doctors?

Intimidation, anxiety, and even impatience are just a few reasons. However, a study published in 2007 found that low health literacy is one of the most influential factors negatively affecting patient communication. Patients with low health literacy ask fewer questions, are less likely to use medical terminology, and ask less meaningful questions (e.g. “What is the name of that medicine?” rather than “Will I be in danger if I increase my dosage?”). Conversations with your doctor are much less beneficial if you don’t know what to say. With such a short amount of time per visit, low-literacy results in missed opportunities for patients to become more engaged and informed about their own health during their doctor’s appointment. Sometimes, patients who are aware of their low health literacy are too embarrassed to ask questions at all.

So, how is this being addressed?

The Agency for Healthcare Research and Quality (AHRQ) released a toolkit for improving health literacy. One of the guidelines was to “Encourage Questions.” Patients with low health literacy can benefit more from their visits if they know what questions to ask. By empowering these patients to see the benefits of speaking up, they can slowly learn that there are no dumb questions and learn to effectively communicate with their doctors. Over time, this increased communication can lead to the gathering of more health information, improved health literacy, better communication, and ultimately better health outcomes.

So, what can we do about this?

AHRQ also published a question guide that can be utilized by all patients, as everyone can stand to benefit from communicating with their doctor. Any MMAL group involved in patient-doctor interactions should keep patient-initiated solutions as an important consideration. Patient involvement indicates to the doctor that the patient is interested and engaged in their own health. It also helps battle the ‘intimidation’ factor in white-coat silence by empowering patients and giving them some authority. In developing our media solutions, the ‘not-dumb’ question we should ask is “How will this help catalyze patient-doctor communication?” because active patients make for happy doctors, which leads to better patient care.

Walking a Mile in a Patient’s Shoes

This past week, I had an appointment with a specialist in the Medical Center. I arrived to my appointment a few minutes ahead of time only to walk into a waiting room crammed full of people. I have never in my life seen a waiting room that full! I hoped that all the people in the waiting room were families of the patients not actual patients as I waited for the nurse to call my name. My hope was not realized, and an hour later I finally was called back to an exam room.

At this point, I was already extremely frustrated and I honestly wished I had canceled the appointment.

When the nurse checked my vital signs, I didn’t even bother to ask what my blood pressure was. When the doctor asked me if I had any other questions, I quickly replied “no.” I didn’t event make an effort to think of any of my concerns. All I wanted to do was to leave. I had quickly transformed into an unengaged patient, just like the patient my team is trying to help.

It made me wonder if new innovations in technology could streamline this process. The main source of my lack of engagement was due to my frustration that built up while I was in the waiting room. My appointment had been a check-up, and there was no reason why I physically had to be in the doctor’s office. Everything could have been done from my home through a platform like Skype (although more secure.) My vital signs could have been recorded by the various mobile applications available and then sent to my doctor. A new smartphone app allows you to record your heart rate using the flash on your camera, and you can buy blood pressure cuffs and readers that connect directly to your smartphone.

This new trend in healthcare is called telemedicine, which means providing healthcare at a distance. Using telemedicine, a patient can have a virtual appointment with their doctor through a webcam. Telemedicine could prove extremely useful for situations such as check-up appointments, where there is no need for a patient to physically be in the doctor’s office. It also might be valuable for psychiatric care or primary care in rural locations. Telemedicine could provide a way for patients to feel less frustrated at their doctor’s appointments. Patients would no longer have to waste time driving to and waiting at their doctor’s appointment. Their appointment would be in the comfort of their homes, which could lead patients to ask more questions and become further involved in their treatment plans. While telemedicine won’t work for every appointment, it is becoming a increasingly feasible and attractive option for several different facets of healthcare.
