The Slow March of the Digital Health Revolution

A recent commentary (SD Dorn. Gastroenterol 2015; 149: 516-20) provides insight on the digital health revolution.

Key points:

  • “Amara’s law –that ‘we tend to overestimate the effect of a technology in the short run and underestimate the effect in the long run’–seems to apply to digital health. Expect short-term gains to be incremental.”
  • The promise of ‘big data’ has not translated into big changes yet.  “Many systems are not interoperable owing to cost, competition, privacy concerns, and technical barriers.”
  • Mobile health, mHeath, “is skewed toward those who need the least help: the young, the fit, and the educated.” And, there is “no evidence supporting the effectiveness of the vast majority of mHealth tools.”

What’s wrong with electronic health records?

  • “The overall evidence that EHRs improve safety and quality is spotty. Cost savings remain elusive.”  Some reasons include that more time is needed and/or flaws in EHR design.
  • EHRs are not very usable –excessive clicks and scrolling.
  • EHRs “reduce productivity and can add hours to the busy clinician’s day”
  • Physicians “now spend up to two-thirds of a typical outpatient visit documenting.”
  • Clinical records may be more legible, but they are often less useful.  “Template-generated notes frequently lack coherent narratives, are bloated with extraneous and repetitive information, and sometimes contain obvious errors that are copied forward from one note to another.”
  • “Physicians suffering from ‘alert fatigue’ may ignore potentially valuable clinical alerts.”
  • EHRs require frequent sign-ins and computers often have to be unlocked.
  • EHRs are expensive.
  • In total, EHRs significantly worsen physician satisfaction.

From a patient vantage, EHRs offer the possibility of patient portals to send physician messages, obtain test results, request medication refills, and schedule appointments.  Telehealth offers the potential for expert advice from great distances.

Some integrated health systems, including the Veteran’s Health Administration and Kaiser Permanente, have shown that EHRs can be successful.

My take: The transition to digital technologies has great promise but could lead to a less personal approach. So far, the transition to digital health has been a bumpy slow road.

Why D5 1/2NS was the Right Choice in the 1950s!

For many, a frequent practice is to order D5 1/2NS intravenous fluids for maintenance IVFs.  An expert review (ML Moritz, JC Ayus. NEJM 2015; 2015: 373: 1350-60) of this topic explains why this was right in the 1950s but is usually the wrong choice today.

Key points:

  • Use of hypotonic maintenance fluids (sodium concentration <130 mmol per liter), “has been associated with a high incidence of hospital-acquired hyponatremia and more than 100 reports of iatrogenic deaths or permanent neurologic impairment related to hyponatremic encephalopathy.”
  • Acutely ill patients have “disease states associated with excess arginine vasopressin.”
  • Recommendations on the use of hypotonic fluids were “based on theoretical calculations from the 1950s, before the syndrome of inappropriate antidiuresis was recognized as a common clinical entity.”
  • “More than 15 randomized, prospective trials involving more than 2000 patients have evaluated the safety and efficacy of isotonic fluids…most of these studies involved children…isotonic fluids were superior.” Limitations: these studies were typically <72 hours and excluded patients with renal disease, heart failure, and cirrhosis.
  • The authors also note potential problems with 0.9% NS for rapid infusion, perhaps related in part to the polyvinyl chloride bags which lowers the pH.  “0.9% saline, as compared with balance salt solutions, may produce a hyperchloremic metabolic acidosis, renal vasoconstriction, an increased incidence of acute kidney injury requiring renal-replacement therapy, and hyperkalemia.”
  • Hypotonic fluids may be appropriate in the setting of established hypernatremia or a clinically significant renal concentrating defect (with free-water losses).

My take: D5 1/2 NS and other hypotonic fluids should not be used commonly as a maintenance fluid.

Off-Duty Doctors and Family Obligations

A mentor (thanks to WFB) forwarded me a recent article from the NY Times: A Doctor at His Daughter’s Hospital Bed written by a well-known (previous) transplant surgeon.

In essence, this article relates the problem a physician has when he suspects that the care a loved one is receiving is deficient and how strongly to advocate in this circumstance. In fact, this physician ended up grabbing/infusing several bags of IV fluids from a crash cart when the treating team was content to observe.  This article is well-written; I wanted to comment on my own struggles in this area.

First of all some background: one lesson that I learned the hard way was to act on your convictions even when this makes you unpopular.  When I was an intern, I was one of several team members in the care of a child with neurological problems.  I relayed my concerns that the child needed more aggressive care to both my supervising resident and to the subspecialty fellow.  Neither of these physicians acted on the problem.  Later in the day, I spoke with the attending physician.  Ultimately he agreed with my assessment but chided me for not contacting him sooner.  From that day forward, I’ve tried to make sure that if I didn’t get the answer I wanted regarding a patient’s care, that I would keep pursuing the matter until I did.  At the same time, it is worthwhile to try to be pleasant; acting in a nasty manner usually worsens the situation.

For my parents and loved ones, I’ve told them that when someone is hospitalized it is important to always have someone nearby to keep track of what is going on.  What medicine is being given?  Why was that imaging study ordered?  Why are the IV fluids being changed?  When will I see the … physician? This person does not have to be a doctor/healthcare provider, though sometimes that helps.

A few years ago, after an orthopedic surgery, my Mom was recovering in a ‘teaching’ hospital (not in Atlanta).  The surgeon had told me to call him if I had any concerns.  As my Mom returned to her room, I noticed that she did not have a pulse oximeter.  I told the nurse that this concerned me because I knew that she was receiving powerful pain relievers which could decrease her breathing.  The nurse tried to assure me that they would do “spot” checks; she said the hospital was full and there may not be enough pulse oximeters.  I insisted that spot checks were not good enough and to go ahead and contact the surgeon since he had asked me to call him with any concerns.  While I never spoke with a surgeon, the pulse oximeter showed up within five minutes.

About two weeks later, I received a call from Mom early on a Sunday morning.  She was having some chest pain.  I asked her if it had ever happened before and she related that it was the same type of pain she had had a few days after her operation.  She explained that this occurred in the middle of the night at the hospital.  Since the nurse told her the pain was due to anxiety and/or a panic attack [she had never suffered from either previously], neither she nor my Aunt wanted to call and wake me up.  So, on that Sunday, of course, I told her to take an aspirin and go straight to the hospital.  The physicians confirmed that she had had a heart attack.  They placed a stent the next day and she fortunately recovered.

My Dad has had a number of health problems.  On my birthday this year, he had to be transferred to the ER.  After his evaluation, we were told that he would need to be observed in the neurology ICU but there was not a bed available until the morning.  He was going to be monitored in the ER until then.  My twin brother is an early riser.  So that night, we agreed that I would stay with Dad until 4 am and he would take over at that point.  I planned to return to Atlanta to see patients (most had been scheduled for many weeks prior).

Fortunately, around 10 pm, one of the ER staff kindly brought me a comfortable foldout chair.  I tried to get a little rest.  Around 11 pm, a physician entered the ER bay.  Since he did not introduce himself, I questioned whether he was relieving the previous ER physician. He said no; he was a hospitalist.  I then asked whether a bed had opened up in the neurology ICU and whether he would like me to give him a brief summary of what had been happening.  His answer was simply that he did not know what the status of the neurology ICU was and that he did not need any information.  As he was leaving the ER bay, without even the briefest of exams, he said that all of the information that he needed was in the computers.  My response was to ask him if he knew how many CT scans my Dad had had in the past week.  He left without answering.

The next day no physician spoke with us until around 5 pm.  The physician seeing my Dad at that time informed us (me by phone) that this was a followup since my Dad had been seen by their group the previous night.  I informed him that the previous physician had neither examined my Dad nor relayed any type of medical plan.  I am grateful that this physician took the time to hear his background, to apologize for his colleague and develop a plan that helped my Dad improve.  At the same, I am bitter, but perhaps enlightened, by the fact that the previous physician did not care or even act like he did.

What I have learned from the other side (the patient’s side) of the bed:

  1. The hospital that I work at is exceptional (Children’s Healthcare of Atlanta).  The doctors and nurses that I work with care deeply about doing their best every single day.  In fact, this attitude permeates the hospital and includes child life specialists, feeding therapists, ward secretaries, and even maintenance staff.  This is probably true for a lot of children’s hospitals.
  2. In many hospitals, you really have to look out for those you care about to lower the chances that their team will overlook important steps.  Even in really good hospitals, this is important.
  3. While skepticism comes natural for those of us in health care, many family members rely too heavily on the expertise of their nurse or physician.  Engage your health care providers to make sure that they understand what you are trying to tell them.  If the situation changes, make sure your team is updated.
  4. Medication errors are so common.  If you don’t bring the medications with you, make sure you know the dose, the route, and the frequency/timing.  Take pictures of the pill(s) and the prescription or write out all of the prescriptions.  Do not be afraid to ask the nurse to show you the “MAR” (medication administration record) so that the reordered medications match up with those that are taken at home.
  5. Small gestures, like getting a comfortable chair for a family member, can make a big difference.
  6. If you are a physician determined to stay on the sidelines, you may regret that decision.

For physicians/healthcare providers reading this blog, what stories have prompted you to jump from the ‘sidelines back onto the field?’  What advice would you add for families? For nonhealthcare providers reading this blog, what suggestions would you offer?

5000% Increase for Well-Established Drug

There is yet another outrageous example of a pharmaceutical company jacking up the price of a medication, without any added innovation, due to monopolizing its production.

From USA Today: Company hikes price 5000%.  Here’s an excerpt:

Turing Pharmaceuticals of New York raised the price of Daraprim from $13.50 per pill to $750 per pill last month, shortly after purchasing the rights to the drug from Impax Laboratories. Turing has exclusive rights to market Daraprim (pyrimethamine), on the market since 1953.

Daraprim fights toxoplasmosis, the second most common food-borne disease, which can easily infect people whose immune systems have been weakened by AIDS, chemotherapy or even pregnancy, according to the Centers for Disease Control.,,,

About 60 million people in the United States may carry the Toxoplasma parasite, according to the CDC. It comes from eating under-cooked meat, cooking with contaminated knives and boards, drinking unclean water and contact with infected cat feces.

Mothers can also pass it to their children during pregnancy and organ transplant patients can get it through an infected donor.

My take: This type of excessive drug cost increase is why critics demand additional regulation be placed over the entire pharmaceutical industry; it can occur only in a system which indirectly shares the cost across the entire system by having insurance companies foot most of the bill.  In my view, this increase in cost is equivalent to the water company jacking up your water bill 5000% –how would you feel about that?

“Not Up For Debate: The Science Behind Vaccination”

Wednesday’s well publicized debate unfortunately discussed vaccination.  Perhaps it is not surprising that a businessman/entertainer, Donald Trump, reiterated misinformation.  Yet, the two former physicians (Ben Carson and Rand Paul) on the stage also provided misleading information.  A good write-up of this issue from the NY Times: Not Up for Debate: The Science Behind Vaccination

Here’s an excerpt:

Here are the facts:

  • Vaccines aren’t linked to autism.
  • The number of vaccines children receive is not more concerning than it used to be.
  • Delaying their administration provides no benefit, while leaving children at risk.
  • All the childhood vaccines are important.

ICD-10: Source for humor?

Like most physicians, I am not terribly excited about the transition to ICD-10.  The increased detail with coding will take longer and be a hassle. However, there is apparently some humor to be derived from the institution of ICD-10.

From HealthcareDive.com: “There are 68,000 billing codes under the new ICD-10 system, as opposed to a paltry 13,000 under the current ICD-9. …Despite the controversy surrounding ICD-10, there is one universally agreed-upon upside to the hyper-specific coding system: Weird and obscure codes that stand for bizarre medical injuries. There’s even an illustrated book, Struck by an Orca: ICD-10 Illustrated.”

Some of the absurd ICD-10 codes from HealthcareDive.com:

  • V97.33XD: Sucked into jet engine, subsequent encounter
  • Y92.146: Swimming-pool of prison as the place of occurrence of the external cause
  • W55.41XA: Bitten by pig, initial encounter​
  • W61.62XD: Struck by duck, subsequent encounter
  • Z63.1: Problems in relationship with in-laws
  • W220.2XD: Walked into lamppost, subsequent encounter
  • Y93.D: V91.07XD: Burn due to water-skis on fire, subsequent encounter​
  • W55.29XA: Other contact with cow, subsequent encounter
  • W22.02XD: V95.43XS: Spacecraft collision injuring occupant, sequela
  • W61.12XA: Struck by macaw, initial encounter
  • R46.1: Bizarre personal appearance

Multiple authorities have weighed in on the issue of which ICD-10 codes are most zany. Here are a few links:

University of South Florida their list includes

  • Knitting and Crocheting (Y93.D1)
  • Pecked by chicken, initial encounter (W61.33XA)

Multibriefs Exclusive their list includes

  • T71.231D Asphyxiation due to being trapped in a discarded refrigerator, accidental
  • V80.730A Animal-rider injured in collision with trolley
  • Z62.1 Parental overprotection
  • T63 Unspecified event, undetermined intent

NY Times: Roughed up by an Orca? There’s a code for that (from 12/29/13) “There are codes for injuries incurred in opera houses and while knitting, and one for sibling rivalry.” This article has some nice graphics, including one of a water skier with the skis on fire.

Does Staying Up All Night Affect Surgery the Next Day?

According to a recent study (A Govindarajan et al. NEJM 2015; 373: 845-33), the answer is no.  That being said, my preference would be for a well-rested surgeon.

Some of the details:

The authors conducted a retrospective, population-based, matched cohort study in Ontario, Canada.  Twelve procedures were analyzed from 1448 physicians and involving 38,978 patients.  The same physicians had his/her procedures compared when they were done after treating patients from midnight to 7am to when these were done on days that were not preceded by night call.  The physicians included in the study were attending physicians; thus this does not provide insight into whether residents or fellows would perform similarly.

Key finding:

  • No difference in any primary outcome: death, readmission, or complication.  This primary outcome occurred in 22.2% after night call and 22.4% without night call.

Here’s a graph below -which depicts, from top to bottom, odds ratio for cholecystectomy (n=9322 patients, 479 physicians), gastric bypass (n=320 patients, 25 physicians), colon resection (n=2214 patients, 315 physicians), hysterectomy (n=7020 patients, 384 physicians), knee arthroplasty (n-2504 patients, 192 physicians), hip arthroplasty (n=1564 patients, 154 physicians), repair hip fracture (n=1192 patients, 166 physicians), lung resection (n=550 patients, 55 physicians), CABG (n=460 patients, 48 physicians), Spine surgery (n=3456 patients, 104 physicians), Craniotomy (n=1396patients, 66 physicians), Angioplasty (n=8980 patients, 130 physicians)

FDA Approves New Drug for Nausea/Vomiting

FDA Announcement -here’s excerpt:

The U.S. Food and Drug Administration approved Varubi (rolapitant) to prevent delayed phase chemotherapy-induced nausea and vomiting (emesis). Varubi is approved in adults in combination with other drugs (antiemetic agents) that prevent nausea and vomiting associated with initial and repeat courses of vomit-inducing (emetogenic and highly emetogenic) cancer chemotherapy….

“Chemotherapy-induced nausea and vomiting remains a major issue that can disrupt patients’ lives and sometimes their therapy,” said Amy Egan, M.D., M.P.H., deputy director of the Office of Drug Evaluation III in the FDA’s Center for Drug Evaluation and Research. “Today’s approval provides cancer patients with another treatment option for the prevention of the delayed phase of nausea and vomiting caused by chemotherapy.”

Varubi is a substance P/neurokinin-1 (NK-1) receptor antagonist. Activation of NK-1 receptors plays a central role in nausea and vomiting induced by certain cancer chemotherapies, particularly in the delayed phase. Varubi is provided to patients in tablet form.

The safety and efficacy of Varubi were established in three randomized, double-blind, controlled clinical trials where Varubi in combination with granisetron and dexamethasone was compared with a control therapy (placebo, granisetron and dexamethasone) in 2,800 patients receiving a chemotherapy regimen that included highly emetogenic (such as cisplatin and the combination of anthracycline and cyclophosphamide) and moderately emetogenic chemotherapy drugs. Those patients treated with Varubi had a greater reduction in vomiting and use of rescue medication for nausea and vomiting during the delayed phase compared to those receiving the control therapy…

The most common side effects in patients treated with Varubi include a low white blood cell count (neutropenia), hiccups, decreased appetite and dizziness.

Varubi is marketed by Tesaro Inc., based in Waltham, Massachusetts.
