Should Doctors ‘Google’ Their Patients?

Beware of what you share. Employers now routinely utilize internet search engines or social network searches to obtain information about job applicants. A survey of 2,184 hiring managers and human resource professionals conducted by the online employment website CareerBuilder.com revealed that 39% use social networking sites to research job candidates. Of the group who used social networks to evaluate job applicants, 43% found content on a social networking site that caused them to not hire a candidate, whereas only 19% found information that that has caused them to hire a candidate.

The top reasons for rejecting a candidate based on information gleaned from social networking sites were provocative or inappropriate photos/information, including information about the job applicants' history of substance abuse. This should not come as a surprise to job applicants in the US. After all, it is not uncommon for employers to invade the privacy of job applicants by conducting extensive background searches, ranging from the applicant's employment history and credit rating to checking up on any history of lawsuits or run-ins with law enforcement agencies. Some employers also require drug testing of job applicants. The internet and social networking websites merely offer employers an additional array of tools to scrutinize their applicants. But how do we feel about digital sleuthing when it comes to relationship that is very different than the employer-applicant relationship – one which is characterized by profound trust, intimacy and respect, such as the relationship between healthcare providers and their patients?


The Hastings Center Report is a peer-reviewed academic bioethics journal which discusses the ethics of "Googling a Patient" in its most recent issue. It first describes a specific case of a twenty-six year old patient who sees a surgeon and requests a prophylactic mastectomy of both breasts. She says that she does not have breast cancer yet, but that her family is at very high risk for cancer. Her mother, sister, aunts, and a cousin have all had breast cancer; a teenage cousin had ovarian cancer at the age of nineteen; and that her brother was treated for esophageal cancer at the age of fifteen. She also says that she herself has suffered from a form of skin cancer (melanoma) at the age of twenty-five and that she wants to undergo the removal of her breasts without further workup because she wants to avoid developing breast cancer. She says that her prior mammogram had already shown abnormalities and she had been told by another surgeon that she needed the mastectomy.

Such prophylactic mastectomies, i.e. removal of both breasts, are indeed performed if young women are considered to be at very high risk for breast cancer based on their genetic profile and family history. The patient's family history – her mother, sister and aunts being diagnosed with breast cancer – are indicative of a very high risk, but other aspects of the history such as her brother developing esophageal cancer at the age of fifteen are rather unusual. The surgeon confers with the patient's primary care physician prior to performing the mastectomy and is puzzled by the fact that the primary care physician cannot confirm many of the claims made by the patient regarding her prior medical history or her family history. The physicians find no evidence of the patient ever having been diagnosed with a melanoma and they also cannot find documentation of the prior workup. The surgeon then asks a genetic counselor to meet with the patient and help resolve the discrepancies. During the evaluation process, the genetic counselor decides to ‘google' the patient.


The genetic counselor finds two Facebook pages that are linked to the patient. One page appears to be a personal profile of the patient, stating that in addition to battling stage four melanoma (a very advanced stage of skin cancer with very low survival rates), she has recently been diagnosed with breast cancer. She also provides a link to a website soliciting donations to attend a summit for young cancer patients. The other Facebook page shows multiple pictures of the patient with a bald head, suggesting that she is undergoing chemotherapy, which is obviously not true according to what the genetic counselor and the surgeon have observed. Once this information is forwarded to the surgeon, he decides to cancel the planned surgery. It is not clear why the patient was intent on having the mastectomy and what she would gain from it, but the obtained information from the Facebook pages and the previously noted discrepancies are reason enough for the surgeon to rebuff the patient's request for the surgery.

Two groups of biomedical ethics experts then weigh in on the case and the broader question of whether or not health care professionals should ‘google' patients. The first group of ethics experts feels that uninvited patient ‘googling' is generally a bad practice for three main reasons:

1. It allows healthcare professionals to withdraw from their patients and start relying on online data and information gleaned from social networking sites instead of interacting with the patient and addressing the key issues head-on.
2. The ‘googling' of patients erodes the trust between the healthcare professional and the patient. Patients might feel a sense of betrayal that the healthcare professional "spied" on them.
3. An internet search or review or social network pages linked to the patient represents an invasion of the privacy of the patient. The patient should have the right to decide what information to disclose and what not to disclose, but by surreptitiously obtaining this information, the healthcare provide circumvents the right to privacy of the patient.

A separate panel of reviewers arrives at a very different conclusion and specifically points to this case as an example where it was imperative to ‘google' the patient. As this panel points out, the genetic counselor used a legal method to search the internet and found information on public Facebook profiles after having found many red flags and inconsistencies in the patient's medical history. By finding the information on Facebook, the surgeon and the counselor were able to prevent a self-injurious, deceptive and possibly fraudulent scheme of the patient to go forward. This panel of experts goes as far as saying that it would have actually been irresponsible to not perform the Google search after all the red flags and inconsistencies were identified.
As with all ethical dilemmas, it is difficult to find the correct answer. The first panel brings up good points that the relationship between a healthcare professional and a patient is characterized by trust and respect of privacy, but I tend to agree with the second panel in the case of this patient. It illustrates that the ‘googling' was able to avert an unnecessary and irreversible surgery. This was not just an indiscriminate ‘googling' or searching of private information on Facebook pages. The action was prompted by very real concerns about contradictory information regarding the patient's medical history. On balance, the benefit of avoiding the unnecessary surgery probably outweighed the risk of harming the trust between the healthcare professional and the patient – one which was already undermined by the patient's deception.

This case is rather unusual because it is probably quite rare that a surgeon or a genetic counselor would find valuable information on a patient by merely searching Google or Facebook for information. The type of information that could be of value to most healthcare providers is not usually disclosed on public sites or social network pages. For example, a cardiologist may be interested in finding out why a patient's cholesterol levels are not decreasing despite being placed on optimal medications and being advised to cut down the dietary intake of cholesterol. The cardiologist may suspect that the patient is not really taking the medications or perhaps eating much more dietary cholesterol than the patient is willing to disclose during the doctor's visits. However, it is unlikely that the patient's Facebook page will chronicle whether or not the patient secretly eats cheese omelets on a daily basis or chooses not to take his cholesterol medications.

On the other hand, other healthcare professionals could find important diagnostic clues when reviewing the Facebook page of a patient. Psychiatrists or psychologists may be able to get a much better sense of a patient's mental health and functioning by reviewing the daily posts and interactions of a patient with friends and family members instead of just having to rely on the brief snapshot when they interview the patient during a 30 minute visit.

The study ""To Google or not to Google: Graduate students' use of the Internet to access personal information about clients." by the psychologists DeLillo and Gale surveyed 854 students enrolled in clinical, counseling, and school psychology doctoral programs in the United States and Canada, asking them how they felt about using Google or social networking websites to learn more about their clients/patients. Interestingly, two-thirds of the psychologists-in-training felt that it was never acceptable or usually not acceptable to use web search engines in order to find additional information about their clients. This feeling was even more pronounced when it came to social networking sites: 76.8% of the students thought that this was never acceptable or usually not acceptable.

However, despite these feelings, 97.8% of the students had searched for at least one client's information using search engines such as Google, whereas 94.4% had searched for at least one client's information using social networking websites. Importantly, 76.8% of the therapists who had conducted the searches for client information on social networking sites also reported that it was either always or usually unacceptable! This suggests a significant dissonance between the ethical perception of the therapists and their actions. Furthermore, more than 80% of the therapists who had conducted the searches said that their clients were aware of the internet and social networking searches they were conducting.

The case study with the patient requesting the mastectomy and the high prevalence of using the internet to perform searches on patients/clients by psychologists highlights the ethical dilemmas that are emerging in our culture of digital sharedom. The internet with its often very public display of individual information may be a powerful tool for certain healthcare professionals, but we also need to develop ethical guidelines for how healthcare professionals should use this tool. For medical procedures and tests, healthcare professionals have to obtain informed consent from their patients, discussing the risks and benefits of the procedure or test. Should healthcare professionals also obtain informed consent from patients before they pry into their social media networks? Or would that defeat the purpose because the patients might change the privacy settings or change the content of their posts, knowing that healthcare professionals might be reviewing them? Should healthcare professionals in specialties such as psychology and psychiatry ‘google' all their patients – just like they now ask questions about substance abuse to all patients – or only if there are certain red flags?

The survey of psychologists-in-training highlights the cognitive dissonance that healthcare professionals may experience: They may reject such searches on their clients or patients in the abstract, but they may still choose to perform the searches, probably because they think it will allow them to provide better care for their clients and patient. Instead of relying of idiosyncratic decisions made by professionals, we have to establish the ethical ground-rules for how healthcare professionals can use search engines or social networking sites when obtaining information about individuals. We may have become so accustomed to invasions of our privacy by government agencies and corporations that we sometimes forget that privacy is instrumental in maintaining our individuality. Especially in relationships that are founded on an extraordinary degree of trust, such as those between healthcare professionals and their patients or clients, we need to ensure that this trust is not eroded by the dark side of sharedom.

Scientism Reloaded

The "Reclaim Scientism" movement is gaining momentum. In his recent book "The Atheist's Guide to Reality: Enjoying Life without Illusions", the American philosopher Alexander Rosenberg suggests that instead of viewing the word "scientism" as an epithet, atheists should expropriate it and use it as a positive term which describes their worldview. Rosenberg also provides a descriptive explanation of how the term "scientism" is currently used:

Scientism — noun; scientistic — adjective.
Scientism has two related meanings, both of them pejorative. According to one of these meanings, scientism names the improper or mistaken application of scientific methods or findings outside their appropriate domain, especially to questions treated by the humanities. The second meaning is more common: Scientism is the exaggerated confidence in the methods of science as the most (or the only) reliable tools of inquiry, and an equally unfounded belief that at least the most well established of its findings are the only objective truths there are.

Rosenberg's explanation of "scientism" is helpful because it highlights the difference between science and scientism. Science refers to applying scientific methods as tools of inquiry to collect and interpret data, whereas "scientism" refers to cultural and ideological views promoting the primacy or superiority of scientific methods over all other tools of inquiry.  Some scientists embrace scientistic views, in part because scientism provides a much-needed counterbalance to aggressive anti-science attitudes that are prevalent on both ends of the political spectrum and among some religious institutions. However, other scientists are concerned about propping up scientism as a bulwark against ideological science-bashing because it smacks of throwing out the baby with the bathwater. Science is characterized by healthy skepticism, the dismantling of dogmatic views and a continuous process of introspection and self-criticism. Infusing science with ideological stances concerning the primacy of the scientific method could undermine the power of science which is rooted in its willingness to oppose ideological posturing.

As a scientist who investigates signaling mechanisms and the metabolic activity of stem cells, I am concerned about the rise of some movements that fall under the "scientism" umbrella, because they have the possibility to impede scientific discovery. Scientific progress relies on recognizing the limitations and flaws in existing scientific concepts and refuting scientific views that cannot be adequately explained by newer scientific observations. An exaggerated confidence in the validity of scientific findings could stifle such refutations. For example, some of the most widely cited scientific papers in the field of stem cell biology cannot be replicated, but they have had an enormous detrimental impact on the science and medicine, in part because of an exaggerated faith in the validity of some initial experiments.


I first began studying the use of stem and progenitor cells to enhance cardiovascular repair and regeneration over a decade ago. At that time, many of my colleagues and I were excited about a recent paper published by a group of scientists based at New York Medical College in the high-profile scientific journal Nature in 2001. The paper suggested that injected adult bone marrow stem cells could be successfully converted into functional heart cells and recover heart function after a heart attack by generating new heart tissue. The usage of adult regenerative cells was a very attractive option because it would allow patients to be treated with their own cells and could circumvent the ethical and political controversies associated with embryonic stem cells. This animal study gained even more traction when supportive experimental and human studies were published by other scientists. Then a German research group under the direction of the cardiologist Bodo Strauer published a paper in 2002 which showed that not only could adult human bone marrow cells be safely injected into heart attack patients but that these adult cells  even appeared to improve  heart function.

The stir caused by these discoveries was not just confined to scientists. The findings were widely reported in the media and I recall numerous discussions with physicians who claimed that cardiovascular disease would soon be a problem of the past, because patients would receive routine bone marrow injections after heart attacks. One colleague even advised me to reconsider my career choices since the usage of bone marrow cells could address most if not all issues in cardiovascular regeneration.

This excitement was somewhat dampened when a refutation of the 2001 Nature paper was published in 2004, also in the journal Nature. A collaborative effort of two US-based stem cell research groups was not able to replicate the findings of the 2001 paper. The scientists were unable to find any significant conversion of adult bone marrow cells into functional heart cells. However, many physicians, scientists and patients had already adopted an unshakable belief in the validity of the bone marrow cell treatments after heart attacks. Hundreds of heart attack patients were being enrolled in clinical trials involving the injection of bone marrow cells. Clinics in Thailand or Mexico began offering bone marrow injections to heart patients from all around the world– for a hefty price, both in terms of monetary payments and in terms of safety because they exposed patients to the risks of invasive injections of bone marrow cells into their hearts.

Despite the fact that the initial clinical studies with small numbers of enrolled patients had shown a beneficial effect of bone marrow cell injections, subsequent trials could not confirm these early successes. It became apparent that even if bone marrow cell injections did exert a therapeutic benefit in heart attack patients, these benefits were rather modest. Scientists increasingly realized that the observed benefits may have been causally unrelated to the small fraction of stem cells contained within the bone marrow. Instead of bone marrow stem cells becoming functional heart cells, some bone marrow cells may have merely released protective proteins which could explain the slight improvement in heart function, without necessarily generating new heart tissue. One of the largest bone marrow cell treatment trials for heart attack patients to date was just recently published in 2013 and showed no evidence of improved heart function following the cell injections.  

In hindsight, many of us have wondered why we were not more skeptical of the initial findings. When compared to embryonic stem cells, adult bone marrow stem cells have a very limited ability to differentiate into cell types other than those typically found in the bone marrow. Furthermore, the clinical studies which reported successful treatment of heart attack patients used unpurified bone marrow cells from the patients. The stem cell content of such unpurified preparations is roughly 1% or less, which means that 99% of the injected bone marrow cells were NOT stem cells. For the tiny fraction of bona fide stem cells in the bone marrow to convert into sufficient numbers of beating heart cells and even create new functional heart tissue would have been akin to a miracle.

Critical thinking and healthy skepticism, the scientific peer review processor and even common sense should have alerted us to the problems associated with these claims, but they all failed. Perhaps scientists, physicians and patients were so excited by the prospect of creating new heart tissue that they suspended much-needed skepticism. Exaggerated confidence in the validity of the scientific data published in highly regarded scientific journals may have played an important role. Unintentional cognitive biases of scientists who conducted the experiments and a disregard for alternative explanations could have also contributed to the propagation of ideas that would withstand subsequent testing. Scientific misconduct may also play a role. For example, the cardiologist who conducted the first clinical studies with bone marrow cell infusions in heart attack patients was investigated by his university for scientific misconduct because a review of his work had identified massive errors.

This is just one example to illustrate problems associated with an exaggerated confidence in the validity of scientific findings, a kind of confidence which scientism engenders. Such examples are by no means restricted to stem cell biology. A recent analysis of scientific reproducibility in cancer research claimed that only 11% of published cancer biology papers could be independently validated, and other areas of scientific research may be similarly afflicted by the problem of irreproducibility of published, peer-reviewed scientific papers.
Increasing numbers of scientists are recognizing that current approaches to interpreting and publishing scientific data are severely flawed. Exaggerated confidence in the validity of scientific findings is frequently misplaced and claims that scientific results represent objective truths need to be re-evaluated particularly when a high percentage of experimental results cannot be replicated by fellow scientists. In this particular context, the views of scientists who are trying to learn lessons from the failures of the scientific peer review process are not so different from those of "scientism" critics. However, many scientists, myself included, remain reluctant to use the expression "scientism".  

Rosenberg illustrates the problems associated with the word "scientism". Since "scientism" is often used as an epithet, invoking "scientism" may impede constructive discussions about the appropriateness of applying scientific methods. While a question such as "Can issues of morality be answered by scientific experiments?" may be important, introducing the term "scientism" with all its baggage distracts from addressing the question in a rational manner.
The other major issue associated with the term "scientism" is its vagueness. It is difficult to discuss "scientism" if it encompasses a broad range of distinct concepts such as the notion that science has to remain within certain boundaries as well as a criticism of overweening confidence in the validity of scientific findings. I can easily identify with asking for a realistic reappraisal of whether or not scientific results obtained by one laboratory constitute an objective, scientific truth but I am opposed to creating boundary lines that forbid certain forms of scientific inquiry because it might infringe on the domains of the humanities. Instead of the diffuse expression "scientism", I prefer the term "science mystique" to criticize the exaggerated, near-mythical confidence in the infallibility of scientific results. 

Rosenberg's view that the expression "scientism" and also the culture of "scientism" should be embraced received a big boost when the scientist Steven Pinker published his polemic essay "Science Is Not Your Enemy: An impassioned plea to neglected novelists, embattled professors, and tenure-less historians". Like Rosenberg, Pinker wants to rehabilitate the expression "scientism" and use it to indicate a positive, science-affirming worldview. Unfortunately, instead of engaging in a constructive dialogue about the culture of "scientism", Pinker reveals his condescending attitude towards the humanities throughout the essay. His notion of respect for the humanities consists of pointing out how much better off classical philosophers might have been if they had been aware of modern neuroscience. 

But Pinker does not comment on the converse proposition: Would scientists be better off if they knew more about philosophy? Pinker goes on to portray scientists as dynamic forward thinkers, while humanities scholars are supposedly weighed down by their intellectual inertia:

"Several university presidents and provosts have lamented to me that when a scientist comes into their office, it's to announce some exciting new research opportunity and demand the resources to pursue it. When a humanities scholar drops by, it's to plead for respect for the way things have always been done."

Pinker glosses over the reproducibility issues in science and reaffirms his faith in the current system of scientific peer review without commenting on the limitations of scientific peer review:

"Scientism, in this good sense, is not the belief that members of the occupational guild called "science" are particularly wise or noble. On the contrary, the defining practices of science, including open debate, peer review, and double-blind methods, are explicitly designed to circumvent the errors and sins to which scientists, being human, are vulnerable."

The philosopher and scientist Massimo Pigliucci wrote an excellent response to Steven Pinker, discussing the flaws inherent in Pinker's polemic and explaining why promoting a culture of scientism or a "science mystique" is not in the interest of science. I also agree with the physicist Sean Carroll who reminds us that we should get rid of the term "scientism"; not because he wants to get rid of a critical evaluation of science, but because he thinks this poorly defined term is not very helpful.

Whether or not we use the word "scientism", it is apparent that the debates between the critics and defenders of the culture of "scientism" are here to stay. It is unlikely that rehabilitating the unhelpful word "scientism" or polemical stances towards the humanities will contribute to this debate in a meaningful manner. The challenge for scientists and non-scientists is to embrace and address the legitimate criticisms of science without promoting the agenda of irrational anti-science bashing.
