Let’s cut through the B.S. and get real about it. Put a hold on all this soft-focus “I live to care!” or “It gives my life meaning…” Here’s the reality. *** You will study your butt off. Nursing science is based on biology, chemistry, microbiology, anatomy, physiology, psychology, sociology and philosophy. Yeah, every single one of them. You will incorporate those into every decision you make in your practice. It’s called critical thinking. You master it and become a professional, or you don’t and you become a robotic technician. Bottom line. Your choice. Oh, and the studying doesn’t stop after you graduate. Nursing school is just the warm-up. *** The work is physically exhausting and emotionally demanding. (more…) *...

Nord, should cause us all to pause: As a commissioner at the U.S. Consumer Product Safety Commission (CPSC), I can attest that no such (regulatory reform) activity is happening at this agency. We certainly have not combed through our regulations to eliminate those that are “out-of-date, unnecessary, [or] excessively burdensome,” as he suggests is being done across the government. Instead, we are regulating at an unprecedented pace and have pretty much abandoned any efforts to weigh societal benefits from regulations with the costs im...

I can’t imagine any psychotherapist sitting at a computer typing notes while there’s a patient on the couch. That would be particularly bad for a patient with self-esteem issues. I imagine that tablets like the iPad may make this a little easier, but what psychotherapists really need is something like a pen tablet (with a stylus rather than touch-screen) or digital ink to mimic taking notes on a pad of paper. The other issue related to EMRs in mental health is the exchange of notes with other physicians. Will an electronic note from therapist back to the primary care physician wind up in the electronic chart that might get sent, say, to an orthopedist or gastroenterologist? The only thing othe...

A number of people asked me at the show what the most innovative thing I’d seen at HIMSS was and my most common answer was Shareable Ink. The interesting thing about Shareable Ink is that they provide such an interesting middle ground between a technical solution and continuation of paper. I remember about 5 years ago when I heard someone describe the perfect clinical documentation system. It was completely flexible. Required little to no training. Supported every possible documentation style. etc etc etc. Then, they acknowledged that what was being described was the paper chart. It was then that I recognized that while EMR can...

If you consider a doctor’s training. Doctors are trained in an incredible volume of information and then how to use that information along with a lot of other variables to be able to evaluate patients conditions, provide care and at the end of the day solve problems. On the other hand, transcriptionists are trained to do repetitive tasks very well with high accuracy. Certainly they have to have some skills with the medical terminology. Also, many have moved beyond transcription into helping with the clinical documentation and ensuring that it’s documented properly. None of this should be news to anyone. Now for the big finish… Which training is more suited for someone doing a million clicks on an EMR? ...

Essentially instead of having to do all these pick lists of information, you’d just record the whole visit with the doctor and that would be all the documentation you’d need. Ok, so that won’t quite work, because you need some things recorded granularly, but the idea of a video EMR was and is really interesting. Thus, you can imagine my interest when I saw this article about a company, CareCam, that’s developing a video based EMR. Here’s a quote from the article: CareCam is developing an EMR system based on video. The idea came to founder and president Shannon Pierce from her days working as a nurse.

However, I’d say that this part of the movement that I’ve been talking about for quite a while. Basically the survival of transcription for the forseeable future.

This change reflects the fact that the transcription profession is evolving into an editing function with the advent of EMRs.The new name and expanded organizational mission will be introduced Feb. 21 at the HIMSS conference. The CDIA will focus on the human interaction necessary to make electronic documentation more usable, a process likely to grow more complicated as the healthcare industry migrates to ICD-10 coding.The cynic in me knows that the public (or mainstream media) won't notice much of a difference because there's still the widespread perception that medical transcription is a booming industry.

I’m still working my way through a  list of questions I posted based on my notes from a series of trainings I delivered across New York State. One that has kept coming up since that time is this one: How do we handle individuals at risk who are only marginally involved in treatment-they miss more appointments than they make, but still come enough that they remain on our caseloads? Mental health care was not organized to fit the way many people at risk utilize services. Much of outpatient mental health is organized around a fantasy that most patients will (1) Make an appoi...

Beyond just the learning curve, there are plenty of EMR software that have a terrible user experience. While I don’t want to totally let EMR vendors off the hook, I do think it’s worth noting that EMR vendors aren’t completely to blame for the unwieldy interfaces. I believe one of the biggest reasons that the EMR documentation interfaces are so terrible is thanks to the crazy insurance billing and documentation requirements. Seriously, it’s a total mess. Everyone that’s involved with insurance billing in healthcare knows what I’m talking about. Trying to code an application that’s easy to use, works well for the docto...

Maybe all of you have heard of “The Impossible Day” but I found the concept interesting and it seems like EMR software could be well positioned to control this issue. Is this a major problem or only a problem for a few people that like to code too high? The RAC audits are an interesting and mindful subject. Some practices have been getting into trouble with the “impossible day” which their EMR’s seem to help perpetuate. Some seem to end up with more documentation in files, but when RAC auditors do the math on how long the docs are supposed to be legitemately spending, its not adding up… Thereby “The ...

Definitely something worth considering when you choose an EMR. How they document and the type of note that it creates matters to the insurance company, matters to you reading the note later, and to some extent the doctors who receive your notes on a referral. Today let’s look at another possible problem with the ugly template note that many EMR systems like to employ (Note: The Jabba the Hut EMR vendors LOVE this type of note). This was sent to me by another reader (Yes, I have the best readers). I know that Medicare RAC auditors apparently love the EMR systems as practices seem to be hanging themselves with poorly maintained patient notes; (ie. “sutures heal...

Here’s a short description of their concern: He [A practice manager] mentioned he’s noticed and heard from many physician colleagues that the insurance payers really seem to be getting more of a caustic demeanor and approach with their subscribers. In particular, they don’t seem to care that an EMR is being used. If anything, they seem to challenge the notes saying the physicians are just using a template and not doing what they say.

The E&M guidelines (for “evaluation and management”), apply to the documentation that physicians are now obligated to provide in support of their Medicare billing. The E&M guidelines, first instituted in 1995 and revised in 1997, were part of the Clintons’ great fraud reduction initiative. Ostensibly, the strict documentation requirements reduce the opportunity for fraudulent billing. While doctors initially railed against the E&M guidelines, they now suffer them in relative silence. The E&M guidelines have become, in fact, just one more hurdle which doctors must navigate as they pick their way through the vast obstacle course ...

One of those that I haven’t seen many people talking about is the transition of Transcriptionists becoming Medical Documentation Specialists. It kind of makes sense that transcriptionists could assist doctors in doing all the granular medical documentation. Certainly the doctor will still be the center of the documentation and they’ll be the source of all the documentation. However, I can quickly see the transcriptionists job continuing to move away from the straight transcribing of voice to text and more and more into the medical documentation arena. This trend had been happening for a while, but I can really see this accelerating as transcript...

A recent piece from the New York Times encapsulates the issue, citing a recent New England Journal of Medicine perspective. According to oncologist Ethan Basch, “Direct reports from patients are rarely used during drug approval or in clinical trials. If patients’ comments are sought at all, they are usually filtered through doctors and nurses, who write their own impressions of what the patients are feeling.” There are a variety of reasons for this. Some doctors feel they have a better sense of the patient’s symptoms than the patient himself. Biases can affect how doctors and nurses perceive symptoms.

Today I came across the best description of the problem with this form of documentation: When a consultant sends you an EMR note, you are reading his Billing Justification. Seems like this post is appropriate for President’s Day. Imagine the founding fathers wrote the constitution or bill of rights in order to justify their billing. We’d have 100 amendments, but only 10 of them that other people needed to read. Luckily our founding fathers had the good sense to only pen what was needed. Maybe we should take a lesson from these amazing men. Related posts:EMR’s Affect on Medical Billing Costs I received an email not too long ago from a...

In my initial concept maps, I included “male gender” as one of the “predisposition” factors, following categories offered by Bryan & Rudd (2006). But then when I saw how therapists used this in clinical practice, I noticed that people would list male gender right alongside suicidal ideation or behavior as if one carries risk in the same way as the other. Obviously they don’t. We have factors like race, where risk looks quite different for men and women and over the lifespan (with young black men at greater risk, and older black women much less).
