Robot Pharmacists
Makarand writes "The next time you visit a pharmacy your prescription may be filled by a robot according to a
TechTV article. Hospitals and drugstores are now increasingly relying on automated technology to count, bottle, and label prescription drugs in a faster and more accurate way. The technology uses a bar-code system similar to those used to read prices in grocery stores. Doctors enter prescription details directly into the pharmacy computer. The robot springs into action when an order is recieved. Riding on a conveyor belt, the robot picks up an empty vial, identifies the bar code of the chosen drug, and automatically fills the drug bottle."
I can understand automating away the cashier or the janitor, but automating away a job where human judgment is so crucial is a terrible idea.
Having seen one of these in action, the device is only as good as the guy filling the drug bins, who thanks to this marvelous technology will be a college intern who stayed up late last night studying for his exams. He will also be the guy checking the picture at the end. "Yup, those are pills."
The robot is less likely to make that mistake than humans.
I don't understand why in the US pharmacists need to fill bottles. It seems such a waste of time, and would seem to increase the cost of medication dramatically.
It would be much easier to have them prepackaged at the manufacturer, so the pharmacist simply reaches in the shelf and grabs the prepackaged box of whatever the doctor prescribed.
This company, http://www.innovat.com (skip flash intro), innovation associates, has some cool technology that does this. For example, if the doctor mistakenly chooses pill A, instead of pill B, the machine will not dispense. Also, you can't fill the Tylenol Aspirin tray with anything but that. It uses some fancy recognition software; it can tell the difference between a skittle and and M&M, plus it won't dispense if pills are deformed (chiped etc.) cool stuff.
Great.

I spent over two years working at NorTel's Bramalea site, which had robotic slide-lines for manufacturing surface-mount component boards. The equipment used tape hoppers of parts, which had individual components mounted on tape similar to a belt-fed machine gun. Once programmed, the robots themselves were flawless, doing exactly what they had been instructed.
The errors that typically cropped up after an assembly program was put in production were caused by good old fashioned human error: loading the wrong parts tape in a hopper (e.g. resistors with the wrong ohm value.)
I cannot see a robotic prescription-filler avoiding this problem. If someone fills the Atenolol (high blood pressure medication) hopper with Viagra, the robot is going to happily count out the correct number of the wrong pills, label them as Atenolol, and leave it up to humans to notice the error.
Cashiers/assistants (sometimes part-time high school or university students) usually hand the packages to customers, not the pharmacist. Even if the bottles aren't pre-bagged, the assistants are very unlikely to notice the pills are the wrong color, size, or shape -- they don't know what the pills are supposed to look like.
While I can see the benefit of a manually fed pill-counter device, all I can forsee from full automation are inevitable mis-filled prescriptions resulting in injury or death of the patients. This is one of the best examples of over-automation I've seen to date.
Some jobs just shouldn't be fully automated, even if we have the technology to do so.
I do not fail; I succeed at finding out what does not work.
I work for a large (Fortune 500) prescription benefit management company. We use automation in all of our mail order facilities, pumping out 60000 prescriptions A DAY. We have had this technology in place for many years and is the only way mail order pharmacies are cheap and effective. The processing has several quality controls, but at the end of the line you still have a human pharmacist checking the drug. This is required by state laws...And yes, even with automation and 7 checks by machinery including an automated image comparison the pharmacist STILL catches errors.
As for the question of resources, if these machines cost a half million dollars each, I'm willing to bet that they are nearly as good as what the drug manufacturers use.
I would expect, although I'm not sure, that a half-million dollar piece of medical equipment would be jam packed with batteries in case of a power failure. In the unlikely occurance of a jam, or a natural disaster taking down most of the electronics (this sounds rather like a straw-man argument to me), there has been a relatively good track record with extra staff. The recent network packet storm in a major hospital comes to mind, everyone was busy but service was not particularly degraded, even with the network completely out of commission.
Besides this, for a regular pharmacy, delays of a day or two to get a prescription filled are not unusual in some cases. Only in emergency cases is this a mission-critical system, and emergency drugs are usually available in places other than the main dispensory.
Hardware, software, and blinking lights!
One the one hand, the robot will probably count faster than old Mr. Mulligan at my local drug store, so I'll get my prescription in 5 minutes instead of 30 minutes.
On the other hand, the robot will probably count more accurately than old Mr. Mulligan, so I won't get the extra 5 or 10 pills that always seem to end up in my prescription bottle.
Mr. Mulligan counting: "15... 20... 25... 30... 25... 30... 35... I think they're making these bottles smaller. I remember when one of these would hold 50 pills... Damn Koreans! I fought a war so we could have decent sized pill bottles..."
I just hope they wait until he croaks before giving the robot his job. He's like 90 or something, it shouldn't be long.
Then you obviously don't know what a pharmacist really does. The 8 or so that I know don't count pills, that's what pharmacy techs do. The real pharmacist looks at the prescription and makes sure the doctor wasn't on crack when he wrote it.
A doctor has to know how the body works and know all the warning signs for about half a million diseases, and the tests for the signs. Are they supposed to know all about 3/4 of a million drugs, their side effects, their dangerous interactions with the other drugs the patient is taking, and the proper dosage?
I don't know how many times I've talked to the pharms' that I know that said some doctor prescribed something that was way too much/little for the patient's body or would've given them side effects that were worse than the origional problem.
Hell, if the town my Grandma's hospital was in had a decent pharm. maybe she'd still be alive, rather than the drugs (to treat the side effects of the drugs (to treat the side effects of the drugs)) causing her kidneys to rot out of her body.

This seems like a great idea, until I read the line - "Doctors type prescriptions into a pharmacy computer system and the orders send the robot into action." This implies a physician (or health care provider if you prefer a more derogatory term the insurance world uses) will actually use technology.... Not just a computer, but a handheld, tablet PC, something with a browser... the chances are slim to none with most of the baby boomers out there.
My first real world experience with CORBA was connecting a Cobol program on a mainframe to a Java application. The Java app would then shoot drug interaction and formulary data to be used by the Physician's winCE handheld. As a former biochemist that spent a serious amount of time working with MD/PhD's in a hospital, the app seemed like a killer idea - response time was fast, the data was secure, and the information was personalized. Then they tried to get them to use the thing. I understand 'you can lead a horse to water' on a whole new level.
Anyhow, there is the human factor as well. It is hard to beat a well designed smart system, but I like the idea of requiring two humans - one to order the drug, another to confirm. The physician spends a surprisingly little amount of time in the real sciences compared to a pharmacist. Different skill set (filtered on what I consider real science). As a side note, pharmacists were pretty good with technology - since they were using Power Builder thick clients and later web interfaces to deal with co-pays, adjudication, interaction warnings, etc.
Counting pills is not hard. Knowing that pill x with pill y scores you a role on the potion miscibility chart is priceless. A real easy fix to "has to read doctor's handwriting" problem? Get them to type the bloody prescription. Wait that would require them to use some funky software ranging from a typewriter to a computer thing...
nah... too hard.
Had this been a toolkit for a pharmacist, it would really take off.

They missed the boat on this one. I work for a mail order pharmacedical company that has been using robotics to do the same thing for many years (atleast the 7 that i've been there).
The most common misconception is that it replaces a pharamcist but by law (atleast here in the Pittsburgh PA area) the pharmacist still looks over the pills in the vial. But a pharmacists time is at a premium and machines are much more capable of doing the job of counting with less errors and faster than a human phar tech.
Overall our "defect" rate is on par with your mom and pop store but our RXs per hour count is much higher.

- "...refills grandpa's heart medication with viagra..."
Funny you should choose that phrase...Sildenafil citrate (Viagra) was orininally researched as a heart medication. Pfizer only found out about the, uh, uplifting side effects when their male test patients were extremely reluctant to return test formulations of the drug.
I think this one truly fits the definition of a "happy accident!"

I have a good friend who owns a large independent pharmacy in New England (I won't be more specific, because I'm not sure if he'd want it mentioned here - though his store and system have been profiled in both trade and general newspapers). He loves it - it handles his top 200 medications, and in his own paraphrased words:
"It lets the pharmacists (of which he is one) spend more time with the patients, and less time counting pills."
He is able to keep a couple fewer pharmacy techs on hand then he used to need for his volume, but it gives the pharmacists a nice assist. He worries less about mistakes - the sanity checks these machines have are a lot more reliable than a human's would be. He's told me he sleeps better at night, knowing the likelihood of a potentially fatal mistake is far lower because of the robot. He sees the role of a pharmacist as being to advise and dispense - with a strong emphasis on the first job.
Here's a true anecdotal story supporting robot usage: I take a Priloec every day. One time I went to my local CVS to get a refill - when I got home and opened the bottle I found Prozac instead (the prescription label was correct - they just filled it with the wrong drug). They took care of the problem immediately, but imagine if I wasn't bright enough to realize that those pills weren't mine (I joke that I'd still have had stomach trouble, but I'd have been happy about it). Fortunately, taking a Prozac per day wouldn't have killed me, but what if it had been something that could have?
That's where I can see robots helping the typical pharmacist. It'll prevent those sort of mistakes from happening, and ensure that the drug ordered is the drug given.

replace the pharmacist, for all the reasons you've stated and more. The point is to automate one of the routine jobs of the pharmacist where mechanical means is less prone to error and removes an act of pure labor from the job.
The pharmacist should, as a matter of course, double check on the work of the robot, because even robots can make mistakes.
This isn't like replacing the pharmacist. It's like giving a ditch digger a backhoe to replace his shovel, or automating a daily incremental system backup so the admin can spend his time and attention somewhere more profitable.

Does this mean hand-writing-recognition has reached a huge milestone to actually understand what the doctor writes?
The problem is that pharmacies and patients don't use the same terms. When your doctor writes you a prescription, you take it to a pharmacy to get it filled. When the pharmacist takes your prescription script, they fill it and then dispense it to you.
When a pharmacy fills a prescription, what they are doing is to take the ordered quantity of the medication out of their stock and package it; when they dispense a prescription, they present it to the patient along with information about how and when to take it. Filling machines as described in the article don't take the place of a pharmacist -- they're taking the place of the pharmacy techs back inside the pharmacy who type up prescription labels, count out pills, and put them in prescription bottles. This means that the people working in the pharmacy don't have to take as much time preparing the prescription, and can spend more time with the patient.
Fill robots don't replace the pharmacist; what they do is eliminate the place where many medication mistakes occur -- selecting and measuring out the drug that the patient will receive. Drug manufacturers deliberately make pills and capsules with different shapes, colors, sizes and markings in order to help both the patients and the pharmacy staff tell them apart, but a pharmacy tech can still make a mistake and pick the wrong canister off the shelf when pulling a medication, and not notice that they've got the wrong little white pill, particularly when they've got lots of prescriptions to fill. A fill robot doesn't make that mistake; as long as the correct drug is in the correct hopper (and it's easier to make sure you've got the right drug when you're only touching the supply to put another 10,000 pills in the hopper, rather than for each of the 60-pill prescriptions that would be filled from that supply), the fill robot will always pick the correct drug.
And the situation is not as generally clear-cut as the article portrays. Where I work -- a major military hospital -- I am the manager for the pharmacy module of the medical information system at the hospital. The pharmacy has a large fill robot that processes refills; patients can either bring in a prescription for refill or use the phone- or web-based refill system to order their refills. Prescriptions entered for refill are processed by the main medical information system (checking to make sure that there are still refills available on that Rx, that the patient isn't trying to refill the Rx too soon, etc.), and then are sent to the fill robot, which fills and labels the refills, which are then distributed to the satellite pharmacies that the patients have selected to pick up their refills. The prescriptions don't need counselling or instructions, because the patient got those when they got the prescription initially.
I work in a retail setting and have actually seen and used one of these robots. This particular model was by Baker, and is a $125,000 piece of equipment. Most facilities implement one of these robots because of extremely high volumes, to assist in the mundane filling tasks associated with pharmacy. I am not aware of any Federal or State Regulation which allows robots to fill your prescription without a pharmacist on duty, so do not assume that automation of pharmacy means lack of supervision. The Baker unit I described above is sent information from a pharmacy computer, not from a doctor. At this point, I consider direct doctor-to-robot input sketchy at best, unless a prototype model. (Imagine your crusty old country physician firing up his Compaq iPaq and transmitting a prescription on his wireless network to the local robot pharmacy...yeah get the picture?) I know of towns in the rural southwest where the pharmacist literally rides into town once a week to fills rxs that day and that day only... But anyway, this particular robot holds about 180 drugs, holds the vials and caps, and actually fills, prints and labels your prescription. This model can fill about 100 rxs per hour and if it breaks, the ancillary staff has to pick up the slack. I like the analogy previously posted that describes the robot as giving a ditch digger a backhoe instead of a shovel. However, I am very concerned about how technology has affected pharmacy over the last 100 years. WE actually used to compound medication, not a pharmaceutical company in the MAJORITY of cases. Does this mean I want to go back to hand-rolling suppositories? (we used to do that too) No. All I ask is that the benevolent readers of /. be concerned that there is a licensed pharmacist on duty no matter WHO or WHAT fills your prescription. If not, then start to panic :-)
