Fee-For-Service & Face-to-Face Time

An op-ed in today's WSJ addresses the Medicare fee for service payment system, Paying Doctors to Ignore Patients
Each fee is meant to reimburse the doctor for the time and skill he or she devotes to the patient. But it is also supposed to pay for overhead, and this is where the problem begins. To Medicare, a doctor’s overhead (or “practice expense”) includes such items as rent, staff salaries and the cost of high-tech medical equipment. When the agency pays a fee to a doctor who has performed a CT scan, it is meant to cover some of the cost of buying or leasing the scanner itself. Services using more expensive equipment generate higher fees....

In contrast, the doctor-patient visit, which involves no expensive equipment, offers no significant profit opportunity. So the best way for a doctor to make money in his practice is not to spend time with patients but to use equipment as much as possible. That means moving the maximum number of patients through the practice, and spending the minimum amount of time with each one.

I can certainly understand the abuse of such a system from the standpoint of ordering unnecessary tests for the sake of paying off an expensive piece of equipment to generate more profit. I certainly recognize the immorality of such practice. But on the grand scheme of things, I have to disagree with the argument that more face-to-face time spent with patients automatically equates to better quality of health care. Advancements in medical imaging technology are giving doctors more targeted and informative information about a patient's condition. These tests can also allow doctors to provide care to a growing number of patients because they do not directly require the doctor's presence.

Although it can be argued that some of these tests, such as CT scans, may sometimes be ordered unnecessarily, it is hard to extend a blanket statement criticizing the utilization of diagnostic imaging and tests over direct patient contact. Such arguments imply that the increased use of such tests equates to reductions in quality of care (as implied by the title of the article: paying doctors to ignore patients). Certainly, face-to-face interaction is an important aspect of establishing a healthy relationship with one's doctor, but it isn't the be all end all when it comes to improving patient prognosis.

I guess the line is blurred between two perspectives. From the optimist's perspective, the use of tests allow doctors to provide better health care to more patients. But there's always the more negative perspective, in which doctors simply view patients as resources, ordering test after test to reap the profits. As discussed in the article, doctors that directly own CT scanners order scans
more frequently than doctors who have access to institutional scanners:
Doctors who do their own CT scanning and other imaging order roughly two to eight times as many imaging tests as those who do not have their own equipment, a 2002 study by researchers at the University of North Carolina found.
I guess a little bit of both views ring true today...

Although my understanding of the health care system is certainly incomplete, I would agree (at this point) with the proposed elimination of fee-for-service payment plans. In my eyes, this would help resolve the latter situation (extraneous ordering of tests to pay overhead).

A cautionary tale from flies

In a story published in Nature News, scientists find that flies become "hypersexual" following chronic exposure to alcohol. In the story, entitled "Drunken flies get hypersexual: Chronic boozing sends male flies chasing after any and every potential mate", neurobiologist Kyung-An Han states that:
"male flies repeatedly exposed to ethanol vapour became less discriminate in their mate selection. The buzzed flies often courted fellow males, pursuing them around the cage while serenading with a traditional fruitfly courtship song played on vibrating wings"
The lesson? Don't get drunk and make bad decisions. Another reason the fruit fly is such a good model organism.

In other news, I'm gearing up to get back to Rice in the next couple of days. The fall semester went well and I'm looking forward to the spring.

Lots of new faces and my own sitcom

This summer, I've met some great people that work in my lab and I've also gotten more acquainted with some friends that I already knew (some other guys from Rice roomed with me in the house this summer). Unfortunately, I've had to balance spending time with them along with work and studying. They've been able to pry me away from studying from time to time, so I'm satisfied with the way the summer has turned out.

In regards to the friends from Rice, I know I'll get a chance to hang out with them a lot more during the semester. But on the other hand, I did meet someone in my lab who goes to school out of state (they're just here for a summer research program) who is leaving next week. Its unfortunate, since we really only started hanging out the last couple of weeks.

In the past, I've always had a very close group of friends that I'm very comfortable with. This summer, however, I've really enjoyed meeting lots of new people and getting to know them. Although we don't share as many interests as I do with my roommates during the year, I've still been able to enjoy spending time with them and building new friendships.

Previously, my attitude was that I already have a close group of friends, so I didn't consciously put out the effort to get to know lots of new people. Now I see that I've been missing out! Since I'll being picking up my things up and moving to a new place for med school/grad school in less than 2 years, I'll have to meet lots of new people and get situated in a new environment all over again. I'm glad that I got a chance to do a little bit of that this summer.

---------------------------------------

Oh by the way, The Office is an awesome TV show! In between all the stuff I've juggled this summer, I worked in the first 3 season on DVD. I can't wait until the fall, when season 4 gets going.

While watching Scrubs in the past, and now The Office, I've made the observation that I could totally write my life into a sitcom. Sure, my life isn't littered with punch lines to be followed by artificial applause (like on Friends), but the situations I find myself in are really quite hilarious. I should start writing down some of the things that happen. For example, I've been having some hilarious conversations with my friends about something that has recently been going on in my life--it could easily be written to an episode or two. You never know, maybe I'll moonlight as a writer for a sitcom after/during med/grad school.

---------------------------------------

Also, I accomplished what I wanted to do in the lab this summer. I've gotten settled in with a great research group and I really feel like I'm situated well enough to balance lab with classes in the fall. I'm only taking 14 hrs of class work, so I'll have an opportunity to do some more work during the semester. During my program at MD Anderson last summer, my project was really just designed to be completed in a summer--we asked a very specific questions and answered it in a number of ways. It was interesting and rewarding, but I didn't enjoy it as much as my time this summer. With this project, I'm starting with the basics and working from the ground up. I've completed some experiments that will serve as preliminary data to point us in various directions to investigate topics in more detail. I've gotten a much clearer picture of the entire process of scientific research, as opposed to just jumping in on some experiments in the middle of a topic.

Humorous MCAT Question

I realize this is totally immature, but I couldn't help laughing when this question came up on my practice exam. Normally, I wouldn't (and shouldn't) find this very funny, but give me a break... I'll laugh at anything to distract me from the fact that I'm taking a 5 hr long exam.

45. An adult male rat that is acyclic is observed to mount females. However, the rat also allows itself to be mounted by male rats. According to the passage, the most likely explanation for these observations is that:


the rat is hermaphroditic, with both male and female sex organs.

the rat has been demasculinized.

the rat has been masculinized but not fully defeminized.

the rat has been defeminized but not fully masculinized.

Picaso on a Mountain!

I just recalled that I took a picture of the side of a mountain/hill that looked remarkably like the face of one of the prostitutes in Picasso's Les Demoiselles d'Avignon. Specifically, the odd position of the mouth, eyes, and nose are noticeably consistent. For example, the individual's right eye is crooked and slightly above the left one. Pretty cool, right?

Take a look for yourself:



Here's the painting in its entirety.

Regarding my last post, my experiments are going really well now! I've worked out most of the kinks in the protocol/methods, so I'm ready to start tackling the questions that we're investigating. Exciting stuff!

My Annual Research Road Block

I'm currently in the midst of my annual 'troubleshooting some aspect of my research project' that has consistently happen to me each time I start up a new project. By now, I've come to expect these difficulties. And this time, I see it as a challenge rather than a hassle. I've got the technique for my project down pretty well, except I keep getting an inconsistent result from a published experiment that I'm trying to repeat. I won't bore you with the details of the experiments...

In the past, I've felt extremely frustrated when I didn't quite understand why something was happening with an experiment. For example, check out this post from about a year ago. NOW I know that I really do enjoy doing this stuff! I feel fortunate that I've really come to understand my attitude toward research. I can't tell you how many times grad-students, post-docs, professors, and even my parents have cautioned me that research can be extremely frustrating if things don't go right. They always say that you REALLY need to LOVE science to pursue a career in research. I think I've come to the realization that I do in fact enjoy research, even when I'm spending tons of time figuring out every aspect of an experiment or technique. I figure that once I perfect a technique, others can use it in their projects as well, bypassing the time spent on troubleshooting the technique.

In regards to sharing information with colleagues who are working on similar, or identical, projects as you, check out this post by Female Science Professor. I'm not sure what my opinion is yet. I figure its different if you run a lab and you dedicate a large portion of your life to your research. At that point, you might be more hesitant about sharing your unpublished protocols or data with others.

Science Stuff, Baseball, and Enchanted Rock

I warn you, this post will be pretty dorky... but here it goes (note: if you want to bypass the science stuff, just jump to the end, there's pictures from my trip to Enchanted Rock).

I'm amazed, and extremely fortunate, that as an undergraduate I get to work on research that incorporates so many great ideas that are very much relevant to contemporary developments in various fields. My current project deals with developing a screen for developmental toxicity of nanomaterials using Zebrafish embryos. As I've mentioned before, my developmental biology class this past semester was really interesting. I've decided to follow up on my interest and work for my professor. Its one thing to talk about developmental processes and the series of inductive events that pattern the embryo, but its so much more amazing when I can look under the microscope and see hundreds of embryos developing in a consistent, indentical pattern.

Its especially awesome that I get to work fairly independently on the project. Not much has been published on the subject, so I really feel a sense of excitement in working on something novel--something that others really haven't done much. We're working in collaboration with the department of Chemistry, who actually discovered one of the molecules that I've working with (carbon fullerenes), and the department of Bioengineering, which is developing many nanomaterials forpplications in targetting tumor cells, diagnostic imaging, and much more. I guess I'm buying into some of the "nano hype". It really it some fascinating stuff.

I took a class during my first semester called Nanotechnology: Context and Content where we discussed many of the social and environmental aspects that come along with the developing field of nanotechnology. Now I actually get to work on answering some of the questions that we asked--pretty awesome!

That reminds me, one of my roommates and I made a scripted news telecast that delves into the subject. We even interviewed a professor in the Civil and Environmental Engineering Department on the subject. I may post that video some time... We also have a "gag-reel" that goes along with it, but I'm not sure I'll be putting the up anytime soon...

----------------------------------

On another note, here's an excerpt of an interesting article from The Economist:

The RNA Revolution: Biology's Big Bang:

"It is too early to be sure if the distinguishing feature of the 21st century will be biological technology, but there is a good chance that it will be...

[The article goes on to discuss the role of RNA in guiding future research]

If RNA is controlling the complexity of the whole organism, that suggests the operating system of each cell is not only running the cell in question, but is linking up with those of the other cells when a creature is developing. To push the analogy, organs such as the brain are the result of a biological internet. If that is right, the search for the essence of humanity has been looking in the wrong genetic direction."

In developmental biology, it has long been understood that RNA lies at the heart of much of embryonic development. Prior to a stage in embryonic development called the mid-blastula transition, where zygotic genes begin to become transcribed, the patterning and induction of embryonic development relies almost entirely on maternal mRNA deposited in the oocyte.

------------------------------------

Lastly, on a less dorky note, the Owls are one win away from making it to the championship series in the NCAA Baseball College World Series! We have to win one out of two against North Carolina, who we beat 14-4 on Sunday. Coach Graham is starting freshmen Ryan Berry, who had a rough outing against Louisville in the opening game of the CWS, but has had great stuff all year. I'm confident that he'll pitch a solid game, now that he's got some experience pitching on such a big stage.

I stopped by the campus store today to check out the CWS T-Shirts--20 bucks for a plain t-shirt for the CWS! I'll just hold out and buy the championship shirt once we win.

-----------------------------------------------

I'll leave you with some pictures from my trip to Enchanted Rock State Park in the Texas Hill-Country a couple of weeks ago. Although it rained on the first day, we had a great time.
