The Evolution of Knowledge, Data, and Communication: Implications for Health Research


Scientific and Lay Knowledge

Throughout human history, knowledge generated by experts- religious, governmental, and scholarly- has been seen as the superior and most respected form of knowledge. Lay knowledge has been seen as more primitive, or a less reliable form of understanding the world. Science has been traditionally more trusted as a source of knowledge; however, scientific knowledge can be abstract, decontextualized, and more difficult to access by the general public.

Often, many discoveries in science were precipitated by observations of lay knowledge; take for example, the practice of hand-washing in healthcare practice, developed from the observations of Ignaz Semmelweiz, the father of hand-washing, who observed lower childbirth mortality in midwife assisted births compared to medical students-which he attributed to hand-washing. On a more current note, the health implications of the mining of vermiculite ore in residents of Libby, Montana were first observed by the community, which then created the impetus for investigation and accountability, resulting in policy changes on a federal level.

Lay knowledge, is and has always been prominent in healthcare and health research. Lay knowledge can includes personal accounts of health and illness (Putland, Baym, & Ziersch, 2011), and is growing in importance in health research where the cooperation of patients and the relevance of lay ideas is moving science from the old paradigm of positivism to constructionism.

In our class discussion, some felt that the term “lay knowledge” in the healthcare sector is more analogous to “feedback”, or “complaints”. These sentiments carry a negative connotation, and may be part of the underlying assumptions that the scientific community have that lay knowledge carries less authority than scientific knowledge.  Yet, these tried and tested methods of communication have been used successfully to push providers, caregivers, and decision-makers to effect change. Lay knowledge in this form has certainly advanced healthcare; particularly in the movement toward patient-centered care. Benchmarking this feedback, for example Press-Ganey or HCAHPS scores, is driving improvement of our healthcare systems.

Qualitative researchers have long valued lay knowledge and used interviews and focus groups to develop theoretical frameworks or to describe a variety of health related experiences and suggest nursing actions.  The movement towards community-based participatory research (CBPR) signals the prominence of lay knowledge in shaping health science research. Examples can be found on the AHRQ website and include: Stroke Telemedicine Access Recovery Project, Building Health Services Research Capacity for Tribes in Montana and Wyoming, Communities as Partners in Cancer Clinical Trials, and Overcoming Health Racial Disparities to name a few.

The public has now assumed a different role in influencing science as evidenced by use of the “crowd”. Epistemologically speaking, "the crowd" draws on the principles of constructionism, that knowledge is co-created. Wikipedia is an excellent example of how lay knowledge has advanced. Crowdsourcing is the umbrella term that overshadows all the activities that can be developed within the context of the crowd. The crowd can be defined differently, ranging from the general public, an international collaboration of scientists, or even a community of gamers. The movement of citizen science http://en.wikipedia.org/wiki/Citizen_science is another great example of how lay knowledge is changing our understanding of the world and the process of knowledge generation. Scientists from the Massachusetts of Technology (MIT) recently collaborated with "citizen-science gamers" to map the neuronal pathways of a mouse retina to help discover the way the brain processes images http://www.huffingtonpost.com/2014/05/05/how-eyes-detect-motion_n_5267623.html

Researchers are also increasingly turning to the crowd as a supporter of research as in the case of crowdfunding.

Thus, as science progresses from a positivist to a constructionist perspective, it is imperative and advantageous to incorporate the lay perspective in research; it keeps science grounded in the real world so that there is a better context to interpret findings and develop future interventions. Lay knowledge helps keeps science meaningful to society, and provides the context for use.

E-communication and health research and healthcare

Since the introduction of the internet, people all over the globe are connecting, communicating, and collaborating at unprecedented rates. According to Intel, in the span of one minute, there are more than 204 million emails sent, $83,000 worth of merchandise sold on Amazon, 20 million photos viewed online, more than 61,000 hours of music played on Pandora, and over 1.3 million video clips viewed on YouTube worldwide http://scoop.intel.com/what-happens-in-an-internet-minute/.

The internet has drastically transformed the way we communicate, supplementing and replacing traditional forms such as letters, faxes, and telegraphs.

E-Communication has now become a mainstay in communicating and collaborating between research institutions, research team members, stakeholders, and even participants. There now exists an opportunity to aggregate data and to perform multisite and international studies that has never existed before. Researchers are able to more actively engage people who may be under-represented in the community without the great expense previously allocated for time and travel. Yet there are barriers to adoption of e-communication in research- questions about data security, sample bias based on who might respond to research using e-communication, as well as compromise and possible loss of data. 

E-communication, by virtue of the prerequisite internet connection, brings up the topic of access and knowledge of using e-communication technologies. With regards to healthcare delivery through an e-communication platform- the issue of disparities is highly relevant, especially among those who are of a lower income level and the elderly. However, the WHO’ report on mHealth http://www.who.int/goe/publications/goe_mhealth_web.pdf states that there are over 5 billion wireless subscribers worldwide, of which, only 30% live in developed countries. Wireless signals today exceed the span of the electrical grid and networks of paved roads, covering over 85% of the global population. Indeed, the potential use of e-communication in a public health safety net system in the US has been explored by Schickedanz et al. (2013), suggesting that this form of communication, unlike previously thought, may have the potential to bridge disparities in healthcare http://nhitunderserved.org/resources/media/documents/833-schickedanz.jgim.13.pdf, and may be a useful tool to address healthcare disparities among certain populations.  

E-communication has changed healthcare delivery dramatically. The impact on mHealth in healthcare delivery, such as monitoring patients with cardiovascular conditions such as hypertension, coronary artery disease and congestive heart failure, is expected to contribute about 47% to chronic disease management revenues in the US and about 79% in China alone http://www.pwc.in/assets/pdfs/telecom/gsma-pwc_mhealth_report.pdf.

Another way e-communication has changed healthcare is reflected in the e-patient movement. Patients now form online communities where they draw on each other as sources of support, knowledge, advice, and identity. The experience of having a connection with someone else who is sharing the same experiences is certainly valuable, yet barriers to adoption may exist: including the potential for misinterpretation or misinformation, lack of access, technophobia, lack of confidentiality, security, and privacy of health information, or perpetuation of negative or erroneous health ideas. A health provider from our group discussion comments that:

“We do encourage patients to communicate with other patients as a form of support system, so I think as we move toward the future, this is yet another form of a meeting or way to communicate that can be done anytime, anyplace, and with a broader reach. It also has risks - once something is put out on the internet, it is very difficult to take it back or change it. The need for "filters" will be important - in that patients will need to be able to "filter" out what is useful and supportive and what is not. Perhaps there will be an even greater responsibility on healthcare professionals to be able to recommend certain web-based communications for patients that are reputable vs. those that are not. It is incumbent on us to educate ourselves as our patients will be.” 
Health information exchange has traditionally occurred in a face-to-face context. The advent of e-communication has transformed how health information is communicated, exchanged, and interpreted in our daily lives. EHealth has not only been described as a system, but a practice as well, emphasizing how integral the internet is becoming in modern day society. Not only have health information systems changed on a societal, governmental, and institutional level with regards to the healthcare system, eHealth has also changed how patients communicate to patients, their support system, and their providers. EHealth has linked providers, patients, and healthcare systems more efficiently, yet some barriers do exist, such as the disconnected or non-existent communication between electronic health record systems, management of provider and patient expectations, and the prohibitive costs of establishing an eHealth system.

One of our nurse practitioners stated in our discussion:

“Differing perspectives currently co-exist and some sort of middle ground will need to be attained. On one hand there are those (both patients and clinicians) who see eHealth strategies as a solution to address problems related to access, quality, cost, and patient engagement and empowerment.  This group is probably more familiar and comfortable with any sort of technology and uses it in other aspects of their lives. On the other hand, there are those patients and providers who see eHealth as potentially problematic - changing the relationship aspect of care, disrupting traditional roles, adding yet an additional burden for both to manage. Most likely they are less comfortable with technology in their daily lives. For eHealth to be successful across populations and among clinicians some sort of compromise between the two poles of attitudes will need to be reached.” 
Data (r)evolution

The paradigm shifts of positivism to constructionism in the generation of knowledge, and the evolution of communication in the internet age has been discussed in the first two sections. In this final section, the paradigm shift of data as a static unit of observation to a dynamic, interactive unit will be discussed.

Public health data has been collected as early as the 1300s, as evidenced by historical records of plague cases http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2486528/. The researchers toolkit for collecting data has since expanded significantly, ranging from the regular go-to’s such as interviews and surveys, to innovations such as social media, big data, and wearable (and ingestible!) http://www.imedicalapps.com/2013/07/ingestible-sensors-symptom-monitoring/ ) sensor technology.

The Internet of Everthing (IoE) is a term that has recently emerged, referring to the way people, processes, data, and things are interconnected through the internet. The Quantified Self (QS) movement was born from the convergence of these pillars of the IoE. Started by two writers of WIRED magazine, QS is now changing the way we look at our health and lifestyle (check out this video and article for a good overview: http://www.economist.com/node/21548493).  

Data from the quantified-self movement has the potential to help researchers understand patients’ movements, and exercise, sleep, eating, mood, and other body patterns for applications in symptom management, intervention efficacy, behavioral modification, and environmental tracking. The list continues to grow.

As such, the characteristics of data have changed. Data are bigger, richer, communicated much more quickly and efficiently, collected unobtrusively, and analyzed and disseminated in real time. New channels of data collection are developing at a phenomenal pace. This data revolution also has implications on the roles that participants and researchers traditionally held- participants are now more active in the collection of data.  Researchers are less active in data collection, but more active and efficient in analysis due to advances in data visualization and analytics and increased interdisciplinary collaboration.
However, there is the potential to generate a lot of useless noise from large scale use of this technology. On the patients’ end- a high level of self-tracking can also be excessive and border on obsession. Ethical issues may also arise due to the de-personification of the research participant.

It is paradoxical that on one hand participants are now more often included in the research process and on the other hand the researcher using big data is now becoming further removed from participants, both geographically, and socially. How do we engage participants in big data research? This makes ethical considerations more difficult to monitor and enforce as a result of the psychological distance from the participant. A recent Facebook controversy over the manipulation of members’ newsfeeds to study emotional impact of news consumption is in line with ethical issues arising from the use of social media in research http://www.slate.com/articles/health_and_science/science/2014/06/facebook_unethical_experiment_it_made_news_feeds_happier_or_sadder_to_manipulate.html.
In addition, the issues of decontextualizing and reductionism will have to be addressed as a result of objectifying and quantifying human behavior in research. 

Summary

This blog discussed the paradigm shifts of 1) scientific to lay knowledge, with the underlying assumptions of positivism and constructionism; 2) movement from traditional communication to e-communication and its implications on the way people interact and collaborate; as well as 3) the shift from data as static units observed and collected by researchers to data as dynamic and unlimited, generated and collected by both researcher and the lay public. Drivers of the paradigm shifts, barriers to adoption and ethical issues were also discussed.

These paradigm shifts encompasses a larger shift in attitudes towards healthcare and healthcare research, driven primarily by advances in internet communications and connectivity, and will have significant impact to the way healthcare and health research is practiced and conducted locally and globally.
