Pit Crews with Computers: Can Health Information Technology Fix Fragmented Care?
I recently posted a new piece that uses technology as a lens for examining some of the fragmentation and coodination problems exhibited by the healthcare system. Here's the abstract.
Fragmentation and lack of coordination remain as some of the most intractable problems facing health care. Attention has often alighted on the promise of Health care Information Technology not least because IT has had such positive impact on many other personal, professional and industrial domains. For at least two decades the HIT-panacea narrative has been persistent even though the context has shifted. At various times we have been promised that patient safety technologies would solve our medical error problems, electronic transactions would simplify healthcare administration and insurance and clinical data would become interoperable courtesy of electronic medical records. Today the IoM is positioning HIT at the center of its new “continuously learning” health care model that is in large part aimed at solving our fragmentation and lack of coordination problems. While the consensus judgment that HIT can reduce fragmentation and increase coordination has intuitive force the specifics are more complicated. First, the relationship between health care and IT has been both culturally and financially complex. Second, HIT has been overhyped as a solution for all of health care’s woes; it has its own problems. Third, the HIT-fragmentation solution presents a chicken-and-egg problem — can HIT solve health care fragmentation and lack of coordination problems or must health care problems such as episodic care be solved prior to successful deployment of HIT? The article takes a critical look at both health care and HIT with those questions in mind before concluding with some admittedly difficult recommendations designed to break the chicken-and-egg deadlock.

Lessons About Medical Error Learned Watching I Love Lucy.
It's no secret that the night staff of a hospital are both over-worked and over-tired. Nor is it any secret that many medical errors occur at night. But until we look at the totality of the human factors making up medical error, we are unlikely to make significant headway in addressing it. A review of the literature suggests that the reason isn't a lack of understanding about the factors which cause human errors, it's concern about the cost of addressing them.
The authors of a recent study in the Journal of the American Medical Association titled, Relationship Between Occurrence of Surgical Complications and Hospital Finances conclude that not only aren’t hospitals doing all they can to reduce medical errors, they actually have no financial incentives to do so.
I'd suggest that financial incentives are behind ineffective efforts to address the issues of staff over-work and the inherent dangers of intermittent shift work.
It's no surprise that another widely reported recent study has found that reductions in the hours medical residents work has not resulted in increased patient safety. The study authors conclude that this is because although residents worked less hours, they did not have a reduced work load. So, like Lucille Ball in the chocolate factory, the trying to cram more work in the same amount of time increased resident error.
The findings of that study need to be seen in combination with the vast amount of scientific research on the increase in errors caused during night shifts. A recent study of nurses working night shifts showed that “on average, the error rate increase 6% after the second night shift in a row, 17% after the third successive night shift and an astounding 35% higher on the fourth night shift.” See also this and this article by the Joint Commission. Although no one disputes the reality that human beings perform best in the day time, every hospital must be fully staffed 24 hours a day. The information is both anecdotal and research based. But no one seems to be listening.
An article in Nursing World does an excellent job of using available research to describe the scope of the problem, but implies that it can be effectively addressed by nurses proactively paying more attention to their sleep patterns. It advises nurses working the night shift to “take control of sleep.” In fact the NSF “recommends that nurses wear wrap around sunglasses when driving home so the body is less aware that it is daylight.” This advice ignores the scientific reality that humans are not as effective or alert at night as they are in the day time. Nor does it consider the human reality that medical shift workers do not have the luxury of using their days to sleep. Like everyone else living in a diurnal world, they must cope with the tasks of family and daily living.
Techniques like wearing dark glasses may work in making a shift to a new rhythm--like travelling to another time zone. But given the unlikeliness of medical staff to convert to a permanent change in their circadian rhthyms, as if they were working in a submarine (and that doesn’t work very well either) the answer is to address the reality that humans are less effective at recognizing problems and completing complex tasks at night. But that’s not where the problem solving is going.

Evidenced Based Practice: When will Law Catch up with Medicine?
Two widely reported studies this week about bed rest for women at risk of preterm delivery and reduction of salt consumption in order to promote heart health highlight two things we don’t think about enough—that a lot of standard medical practices are without any foundation in science and a lot of legal ones probably are too. However, medicine has more and more taken the public health approach of examining the practices of individual doctors to see how effective they actually are in the general population. For example, it is old news that prescribing bed rest to pregnant women at risk of preterm delivery is not effective. But what this Obstetrics & Gynecology study found that “activity restriction”, such as quitting work, is still prescribed to one at three women at risk for preterm delivery. The accompanying “Bed Rest in Pregnancy: Time to Put the Issue to Rest” makes an ethical argument that continuing to prescribe bed rest in the absence of evidence of its effectiveness violates the principles of autonomy and beneficence.
The Institute of Medicine just issued this report Sodium Intake in Populations: Assessment of Evidence “found no consistent evidence to support an association between sodium intake and either a beneficial or adverse effect on most direct health outcomes other than some CVD outcomes (including stroke and CVD mortality) and all-cause mortality.”
We have similar research in law- a lot of it coming from the Empirical Legal Studies movement, including work done at the Center for Empirical Legal Research at Washington University Berkeley Emperical Legal Research , the Centre for Emprical Legal Studies at UCL (formerly known as University College London) among many others, but it is not as well funded or coming from as well established sources as the studies which attempt to find an evidence basis for medical practices. The salt reduction report was commissioned by the Institute of Medicine In contrast, the ACLU supports its empirical argument that the death penalty does not deter crime on an opinion survey of police chiefs. Translating information from research scientists to practicing physicians is still a slow process,—but no one questions the underlying principle that medical practice should be based on scientific evidence.
Part of the issue is funding. Medicine as a whole is in a constant quest to contain costs and stopping ineffective practices is an important component of that effort. But beyond a small number of progressive funders like the Robert Wood Johnson Foundation, there isn’t a lot of demonstrable interest, the kind supported by funding studies, in law making bodies in finding out what legal practices work and what do not.
This isn’t a new observation. Bryant Garth outlined the problem in 1997 when he explained the importance of more social science research into the foundational principles of practices civil procedure. But the steady flow of studies questioning conventional wisdom coming from the medical field has, as yet, no real counterpart in the world of law making.
Of course there will always be the problem of knowing the unknowable. But it would be interesting for law makers to consider taking a lesson from public health in challenging assumptions about the human body and mind or even more generally the physical world that underlie both common law and statutes.
