Why Don’t Patients Fill Their Primary Care Physician’s New Prescriptions?

A Canadian study published today in the Annals of Internal Medicine suggests that about one third of new prescriptions (written by primary care physicians) are never filled. Over 15,000 patients were followed from 2006 to 2009. Prescription and patient characteristics were analyzed, though patients were not directly interviewed about their rationale for not filling their prescriptions.

In short, patients were less likely to fill a prescription if the treatment was expensive, but certain types of drug indications had consistently higher non-fill rates:

  • Headache (51% not filled)
  • Ischemic heart disease (51.3% not filled)
  • Thyroid agents (49.4% not filled)
  • Depression (36.8% not filled)

Overall, hormonal (especially Synthroid), ENT (especially Flonase), skin, and cardiovascular drugs (especially statins) had the highest non-fill rates.

As far as those prescriptions more likely to be filled, antibiotics (especially for urinary tract infections) ranked number one.

Trends towards prescription compliance were seen among older, healthier patients, and those who were switching medications within a class rather than starting an entirely new drug. Patients who received prescriptions from a doctor that they visited regularly (rather than a new provider) were also more likely to fill their prescriptions.

This study was not designed to elucidate the exact rationale behind prescription non-adherence, but I am willing to speculate about it. In my experience, patients are less likely to fill a prescription if a reasonable over-the-counter alternative is available (think headache or allergy relief). I also suspect that they are less likely to fill a prescription if they believe it won’t help them (skin cream) or isn’t treating a palpable symptom (statin therapy for dyslipidemia). Finally, patients are probably nervous about starting a medicine that could effect their metabolism or cognition (thyroid medication or anti-depressant) without a full explanation of the possible benefits and side effects.

I was surprised to see how compliant patients seem to be with antibiotic agents (at least, filling the initial prescriptions). Given the increasing rates of antibiotic resistance, this reinforces the need to limit prescriptions to those agents truly indicated, and to analyze bacterial sensitivities during the treatment process to optimize medical management.

My take home message from this study is that providers need to do a better job of explaining the reasoning behind new prescriptions (their necessity, consequences of non-compliance, and risk/benefit profiles) and reviewing the overall cost to the patient. If a cheaper, effective alternative is available (whether OTC or generic), we should consider prescribing it. Providers can likely improve medication compliance rates with a little patient education and price consciousness. Extra time should be spent with patients at higher risk for non-compliance due to their personal situation (age, degree of illness, income level) or if a specific drug with lower compliance rates is being introduced (Synthroid, statins, etc.) Regular follow up (especially with the same prescriber) to ensure that prescriptions are filled and taken as directed is also important.

Failure To Communicate: The Dangers Of Inadequate Hospital Handoffs And What To Do About It

One of my biggest pet peeves is taking over the care of a floor-full of complicated patients without any explanation of their current conditions or plan of care from the physician who most recently treated them. Absent or inadequate verbal and written “handoffs” of patient care are alarmingly common in my experience. I work primarily as a locum tenens physician, traveling across the country to “cover” for my peers on vacation or when hospitals are having a hard time recruiting a full-time MD. This type of work is particularly vulnerable to gaps in continuity of care, and has heightened my awareness of the prevalence of poor sign-outs.

Recent research suggests that communications lapses are the number one cause of medical errors and adverse events in the healthcare system. An analysis published in the Archives of Internal Medicine suggests various kinds of consequences stemming from inadequate transfer of information, including missed diagnoses, incomplete work ups, ICU admissions, and near-miss errors. I have personally witnessed all manner of problems, including medication errors (the patient’s full list of medical conditions was not known by the new physician), lack of follow up for incidental (though life-threatening) findings discovered during a hospital stay, progression of infection due to treatment delay, inappropriate antibiotic therapy (follow up review of bacterial drug resistance results did not occur), accidental repeat fluid boluses in patients who no longer required rehydration (and had kidney or heart failure), etc.

It has long been suspected, though not unequivocally proven, that sleep deprivation (due to extended work hours and long shifts) is a common cause of medical errors. New regulations limiting resident physician work hours to 80 hours a week have substantially improved the quality of life for MDs in training, but have not made a remarkable difference in medical error rates. In my opinion, this is because sleep deprivation is a smaller contributor to the error problem than incomplete information transfer. If we want to keep our patients safe, we need to do a better job of transferring clinical information to peers assuming responsibility for patient care. This requires more than checklists (made popular by Atul Gawande et al.), it’s about creating a culture of carefulness.

Over the past few decades, continuity of care has been undermined by a new “shift worker” or “team”  approach. Very few primary care physicians admit patients to local hospitals and continue to manage their care as inpatients. Instead, hospitalists are responsible for the medical management of the patient – often sharing responsibility as a group. This results in reduced personal knowledge of the patient, leading to accidental oversights and errors.  The modern shift-worker model is unlikely to change, and with the rise of locum tenens physicians added to the mix – it’s as if hospitalized patients are chronically cared for by “float staff,” seeing the patient for the very first time each day.

As a physician frustrated with the dangers of chronically poor sign-outs, these are the steps that I take to reduce the risk of harm to my patients:

1. Attend nursing change of shift as much as possible. Some of the most accurate and best clinical information about patients may be obtained from those closest to them. Nurses spend more face-to-face time with patients than any other staff members and their reports to one another can help to nip problems in the bud. I often hear things like, “I noticed that Mr. Smith’s urine was cloudy and smelled bad this morning.” Or “Mrs. Jones complained of some chest pain overnight but it seems to be better now after the Percocet.” These bits of information might not be relayed to the physician until they escalate into fevers, myocardial infarctions, or worse. In an effort to not “bother the physician with too much detail” nurses often unwittingly neglect to share subtle findings that can prevent disease progression. If you are new to a unit or don’t already know the nursing staff well, join their morning or evening sign out meeting(s). They (and you) will be glad you did.

2. Pretend that every new patient needs an H&P (complete history and physical exam). When I pick up a new patient, I comb through their medical chart very thoroughly and carefully. I only need to do this once, and although it takes time, it saves a lot of hassle in the long run. I make note of every problem they’ve had (over the years and currently) and list them in a systems-based review that I refer to in every note I write thereafter.

3. Apply the “trust but verify” principle. I read other physicians’ notes with a careful eye. Electronic medical records systems are notorious for “copy and paste” errors and accidentally carrying over “old news” as if it were an active problem. If a physician notes that the patient has a test or study pending, I’ll search for its result. If they are being treated empirically for some kind of infection, I will look for microbiologic evidence that the bug is sensitive to the antibiotics they are receiving. I’ll ask the patient if they’ve had their radiology study yet, and then search for the result. I’ll review the active medication list and see if one of my peers discontinued or started a new medicine without letting me know. I never assume that anything in the medical record is correct. I try my best to double check the notes and data.

4. Create a systems-based plan of care, reconcile it each day with the active medication list. I like to organize patient diseases and conditions by body systems (e.g. cardiovascular, endocrine, gastrointestinal, neurologic, dermatologic, etc.) and list all the diseases/conditions and medications currently being offered to treat them. This only has to be done thoroughly one time, and then updated and edited with additional progress notes. This helps all consultants and specialists focus in on their particular area of interest and know immediately what is currently being done for the patient (both in their system of interest and as a whole) with a glance at your note. Since medications often have multiple purposes, it is also very helpful to see the condition being treated by each medication. For example, if the patient is on coumadin, is it because they have a history of atrial fibrillation, a prosthetic heart valve, a recent orthopedic procedure, or something else? That can easily be gleaned from a note with a systems-based plan of care.

5. Confirm your assessment and plan with your patient. I often review my patients’ medication and problem list with them (at least once) to ensure that they are aware of all of their diagnoses, and to make sure I haven’t missed anything. Sometimes a patient will have a condition (otherwise unmentioned in their record) that they treat with certain medications at home that they are not getting in the hospital. Errors of omission are not uncommon.

6. Sign out face-to-face or via phone whenever possible. These days people seem to be less and less eager to engage with each other face-to-face. Texting, emailing, and written sign-outs often substitute for face-to-face encounters. I try to remain “old school” about sign-outs because inevitably, something important comes up during the conversation that isn’t noted in the paper record. Things like, “Oh, and Mr. Smith tried to hit the nursing staff last night but he seems calmer now.” That’s something I want to know about so I can preempt new episodes, right nursing staff?

7. Create a culture of carefulness. As uncomfortable as it is to confront peers who may not be as enthusiastic about detailed sign-outs as I am, I still take the initiative to get information from them when I come on service and make sure that I call them to provide them with a verbal sign-out when I’m leaving my patients in their hands. By modeling good sign offs, and demonstrating their utility by heading off problems at the pass, I find that other doctors generally appreciate the head’s up, and slowly adopt some of my strategies (at least when working with me). I have found that nurses are particularly good at learning to tell me everything (no matter how small it may seem at the time) and have heard time and again that things “just run so much more smoothly” when we communicate and even “over-communicate” when in doubt.

“The Devil is in the details.” This is more true at your local hospital than almost anywhere else. Reducing hospital error rates is possible with some good, old-fashioned verbal handoffs and a small dose of charting OCD. Let’s create a culture of carefulness, physicians, so we don’t get crushed with more top-down bureaucratic rules to solve this problem. We can fix this ourselves, I promise.

10 Steps To Finding A Good Doctor And Having A Great Healthcare Experience

I’m excited to announce that US News and World Report has invited me and some other social-media savvy physicians to participate in a live Twitter chat about how to find a good doctor. The chat will be held on Thursday, March 20th at 2pm EST. You can join the conversation by following the #DoctorFinder hashtag or take the pre-chat poll here.

Most people, including physicians, rely on personal references to find a good doctor. But what do you do when you’re far from home, or you don’t know anyone with firsthand knowledge of local doctors? My parents recently asked me to recommend a physician for them in a state where I knew none of my colleagues personally. This is the 10-step process that I used to help them navigate their way to an excellent specialist – I hope it helps others you find the right doctor as well!

1. Determine what kind of doctor you need. You’d be surprised how many different specialists treat the same symptom – depending on its underlying cause. Take “back pain” for example – should you see a primary care physician, an orthopedist, a neurosurgeon, an anesthesiologist, a rheumatologist, or a rehab specialist to evaluate your symptoms? That depends on the cause of the pain, which might not yet be evident to you. The first step to finding a good physician is to figure out which type is best suited to your potential diagnosis. Bouncing from specialist to specialist can be costly, so if you’re not sure which kind of physician specializes in treating your disease or condition (or if you haven’t been diagnosed yet), start with a primary care physician first.

If you’d like to ask an online physician about your symptoms (or find out which specialist would be the most appropriate for you or your loved one),  eDocAmerica.com is my favorite online physician consultant service (note that I answer questions for them.)

2. Compile a list of all the doctors (of the specialty you need) in your area. This list can be generated by your insurance carrier or by an online search of doctor-finder databases such as Healthgrades.com, Vitals.com, or US News & World Report’s Doctor Finder directory.

3. Narrow online choices by your preferences (available via  Healthgrades.com or Vitals.com databases.) Check out the doctors’:

  • Hospital affiliation(s)
  • Office location(s)
  • Educational background
  • Specialty interests
  • Languages spoken
  • Years in practice
  • Gender
  • Types of insurance accepted
  • Review CV if available (often on affiliated hospital website)
  • Check out patient reviews (take them with a grain of salt in case they are skewed by an unfairly disgruntled patient)
  • Make sure they’re accepting new patients
  • 4. Do an online “background check” of your top choices.

    5. Make an appointment – consider the following qualities in a good physician experience:

    • The team: courteousness of scheduling staff, professionalism of nurses, PA’s, techs, etc.
    • Facilities – cleanliness, comfort
    • Medical records/communication – how will they provide you your data? EMR? Email?
    • Timeliness/convenience

    6. Come prepared

    • Bring your list of medications
    • Bring a list of your medical and surgical history/conditions
    • Bring a list of your allergies
    • Bring contact information for your other physicians/providers
    • Bring your insurance information

    7. Ask the right questions

    • How many procedures (like the one I’ll need) have you performed previously?
    • What are the risks/benefits of the procedure? Alternatives?
    • What should I read to learn more about this?
    • If unsure of diagnosis: What else could this be?
    • Are there other medicines that are less expensive that we could substitute?

    8. Go with your gut

    • Did the doctor explain everything clearly?
    • Did the doctor seem to care about you?
    • Do you trust your doctor to be thorough with follow up?
    • Do you like your doctor?

    9. Get a second opinion

    • If the doctor did not meet your expectations in any significant way, find another one
    • If you want to be sure that you’re on the best path, get a second opinion from one of his/her peers or do it online: eDocAmerica (for generalist questions), Best Doctors (to be matched with top national specialists)

    10. Reward good doctors with good online recommendations so others can benefit. Physician ratings are only as reliable as the reviewers. Help other patients locate good doctors by promoting those who deserve it.

    Dr. Val’s Health Tips: Causes And Cures For Childhood Insomnia

    Thanks to support from OTCSafety.org, I’ve created a series of health tips for common medical concerns. This week’s article is about how to diagnose and treat sleep difficulties in children and adolescents. There are many possible causes of insomnia, which include everything from emotional distress to bad dreams, breathing problems, stomach pains, medical conditions or behavioral problems.

    In my article I discuss how you can work with a healthcare professional to determine the cause of your child’s sleep difficulties (this includes details on how to keep a sleep diary). I offer instructive do’s and don’ts to promote healthy sleep, and offer examples of symptoms that may require medical intervention.

    GMO Paranoia And The Hollow Health Claims Of Cheerios

    Make no mistake about it. General Mills’ introduction of Cheerios sporting the label “Not Made With Genetically Modified Ingredients” is a mere marketing ploy and has nothing to do with health or nutrition. Let’s start the dissection of this blatant attempt to capitalize on the anti-GMO paranoia by looking at the main ingredient in Cheerios, namely oats. Samuel Johnson, the 18th century writer who compiled the first authoritative dictionary of the English language whimsically defined oats as the grain “eaten by people in Scotland, but fit only for horses in England.” A clever Scot supposedly retorted “that’s why England has such good horses, and Scotland has such fine men!”

    Modern science, as it turns out, supports the ancient Scotch penchant for oats. A form of soluble fiber in the grain known as beta glucan has been shown to reduce levels of cholesterol in the blood which in turn is expected to reduce the risk of heart disease. You couldn’t tell this by the Scottish experience, though. Scotland has one of the highest rates of heart disease in the world. It seems all that haggis, refined carbs and a lack of veggies is too great a challenge for Scotch oats to cope with. Actually you need at least 3 grams of beta glucan daily to have any effect on blood cholesterol and that translates to roughly a cup of cooked oat bran or a cup and a half of oatmeal. Or about three servings of Cheerios. And that makes the cholesterol lowering claims prominently featured on the Cheerios box ring pretty hollow. There are far better ways to reduce cholesterol than gorging on Cheerios.

    At least, though, the cholesterol lowering claim has some scientific merit. The “no GMO” claim has none. To start with, there are no genetically modified oats grown anywhere, at least not in the current sense of the term which refers to the splicing of specific foreign genes into the DNA of a seed. Such “recombinant DNA technology: is generally used to confer resistance to herbicides or protection from insects, but resistance to drought and enhancement with nutrients hold great potential. Although it is this new-fangled technology that garners attention these days, the fact is that virtually everything we eat has been genetically modified in some fashion over the years, either by traditional crossbreeding or through the use of chemicals or radiation both of which can scramble the genetic material in crops. The latter processes are based on the hope that a useful mutation will occur by chance, but basically it comes down to a roll of the dice. Just do enough experiments and a valuable mutant may surface. Radiation breeding has produced many varieties of rice, wheat, peanuts and bananas that are now widely grown. If you are eating red grapefruit, or sipping premium Scotch whisky made from barley, you are enjoying the products of this technology.

    So if “genetically modified” oats do not exist, what sort of monsters is General Mills protecting us from? As is the case with any commercial cereal, Cheerios contains a number of ingredients with nutritious whole grain oats at the top of the list. Next come modified corn starch and sugar. It is to these two ingredients that General Mills refers when it talks about “GMO-free.” Much of the corn and some of the sugar beets grown in North America are genetically modified to resist herbicides and ward off insects. But by the time the highly processed starch and sugar extracted from these plants reach the food supply, they retain no vestige of any genetic modification. There is no way to distinguish the starch or sugar derived from genetically modified plants from the conventional varieties. The GMO-free Cheerios will not differ in any way from the currently marketed version except that the price may eventually reflect the greater cost of sourcing ingredients from plants that do not benefit from recombinant DNA technology.

    The reason for the addition of sugar to Cheerios, actually in small doses compared with other cereals, is obvious. But why is corn starch added, and why is it modified? Nobody likes soggy cereal, and a thin layer of modified starch sprayed onto the little “O”s helps keep the interior dry. The modification in this case has nothing to do with genetic modification. Starch is a mixture of essentially two “polymers,” or giant molecules, both composed of units of glucose joined together. In amylose, the glucose units form a straight chain, while in amylopectin, the main glucose strand features many branches of shorter glucose chains. The properties of any starch depend on the relative proportion of amylose and amylopectin as well as on the degree of branching.

    Starch has many uses in the food industry. It can thicken sauces, prevent French dressing from separating, substitute for fat or keep cereals dry. But these uses require starches of specific composition, either in terms of the length of the glucose chains or the degree of branching. In other words, the native starch has to be “modified” by treatment with acids, enzymes or oxidizing agents. There is no safety issue here, modified starches are approved food additives. Of course that doesn’t prevent scientifically illiterate alarmists from scaring the public by blathering on about modified starch being used as wallpaper glue and insinuating that any food made with it will literally stick to our ribs. The modified starch used in glue, namely a “carboxymethylated” version, is not the same as used in food, but even if it were, so what? Just because water can be used to clean garage floors and is found in tumours doesn’t mean we can’t drink it. Talking about washing garage floors, Cheerios also contains tripotassium phosphate, a powerful cleaning agent. It is added in small amounts to adjust the acidity of the mix used to formulate the cereal. This too has raised the ire of some ill-informed activists who do not realize that we consume all sorts of naturally occurring phosphates regularly in our diet. Quacking about the dangers of tripotassium phosphate in Cheerios makes about as much sense as hyping Cheerios that are “Not Made With Genetically Modified Ingredients.”

    Latest Cartoon

    Richmond, VA – In an effort to simplify inpatient medical billing, one area hospitalist group has determined that “altered mental status” (ICD-9 780.97) is the most efficient code for use in any patient work up.

    “When you enter a hospital, you’re bound to have some kind of mental status change,” said Dr. Fishbinder, co-partner of Area Hospitalists, PLLC. “Whether it’s confusion about where your room is located in relationship to the visitor’s parking structure, frustration with being woken up every hour or two to check your vital signs, or just plain old fatigue from being sick, you are not thinking as clearly as before you were admitted. And that’s all the justification we need to order anything from drug and toxin screens, to blood cultures, brain MRIs, tagged red blood cell nuclear scans, or cardiac Holter monitoring. There really is no limit to what we can pursue with our tests.”

    Common causes of mental status changes in the elderly include medicine-induced cognitive side effects, disorientation due to disruption in daily routines, age-related memory impairment, and urinary tract infections.

    “The urinalysis is not a very exciting medical test,” stated Dr. Fishbinder. “It doesn’t matter that it’s cheap, fast, and most likely to provide an explanation for strange behavior in hospitalized patients. It’s really not as elegant as the testing involved in a chronic anemia or metabolic encephalopathy work up. I keep it in my back pocket in case all other tests are negative, including brain MRIs and PET scans.”

    Nursing staff at Richmond Medical Hospital report that efforts to inform hospitalists about foul smelling urine have generally fallen on deaf ears. “I have tried to tell the hospitalists about cloudy or bloody urine that I see in patients who are undergoing extensive work ups for mental status changes,” reports nurse Sandy Anderson. “But they insist that ‘all urine smells bad’ and it’s really more of a red herring.”

    Another nurse reports that delay in diagnosing urinary tract infections (while patients are scheduled for brain MRIs, nuclear scans, and biopsies) can lead to worsening symptoms which accelerate and expand testing. “Some of my patients are transferred to the ICU during the altered mental status work up,” states nurse Anita Misra. “The doctors seem to be very excited about the additional technology available to them in the intensive care setting. Between the central line placement, arterial blood gasses, and vast array of IV fluid and medication options, urosepsis is really an excellent entré into a whole new level of care.”

    “As far as medicine-induced mental status changes are concerned,” added Dr. Fishbinder, “We’ve never seen a single case in the past 10 years. Today’s patients are incredibly resilient and can tolerate mixes of opioids, anti-depressants, anti-histamines, and benzodiazepines without any difficulty. We know this because most patients have been prescribed these cocktails and have been taking them for years.”

    Patient family members have expressed gratitude for Dr. Fishbinder’s diagnostic process, and report that they are very pleased that he is doing everything in his power to “get to the bottom” of why their loved one isn’t as sharp as they used to be.

    “I thought my mom was acting strange ever since she started taking stronger pain medicine for her arthritis,” says Nelly Hurtong, the daughter of one of Dr. Fishbinder’s inpatients. “But now I see that there are deeper reasons for her ‘altered mental status’ thanks to the brain MRI that showed some mild generalized atrophy.”

    Hospital administrators praise Dr. Fishbinder as one of their top physicians. “He will do whatever it takes to figure out the true cause of patients’ cognitive impairments.” Says CEO, Daniel Griffiths. “And not only is that good medicine, it is great for our Press Ganey scores and our bottom line.”

    As for the nursing staff, Griffiths offered a less glowing review. “It’s unfortunate that our nurses seem preoccupied with urine testing and medication reconciliation. I think it might be time for us to mandate further training to help them appreciate more of the medical nuances inherent in quality patient care.”

    Dr. Fishbinder is in the process of creating a half-day seminar on ‘altered mental status in the inpatient setting,’ offering CME credits to physicians who enroll. Richmond Medical Hospital intends to sponsor Dr. Fishbinder’s course, and franchise it to other hospitals in the state, and ultimately nationally.
