ShortNote – Clinical Shorthand 1.0

By •• Posted in EMR, HPI, Patient Care

I have worked with home-grown and commercial Electronic Medical Records (EMRs) for over thirty years. The use of “dot commands” (a period followed by a trigger phrase) is about as old as personal computing. (I first encountered dot commands in the WordStar word processing program in the 1980s!) These commands generally fall into three categories: a) links to retrieve data (name, age, lab values, etc.), b) links to specialized services or applications and c) macros that expand into “canned” text. I’ve always found the later somewhat cumbersome and an impediment to fluent typing.

While working on a new set of macros for my Rational HPI Project, it struck me that all those periods were getting in my way. (I can touch type but special characters generally slow me down.) This is particularly true when using many short fragments. I decided to experiment with a standardized clinical shorthand. That lead me to develop these criteria:

  1. Include common abbreviations when they exist.
  2. Expand common but potentially dangerous abbreviations into plain text.
  3. Make the triggers (aka “shorts”) as mnemonic as possible.
  4. Prevent transformation of non-shorthand text. (A paragraph of plain text should generally pass through unchanged.)
  5. Limit punctuation and the need to use modifier keys (i.e., shift, alt, control, etc.). This is especially important for handheld devices such as tablets and smartphones.

My first attempt resulted in approximately 130 Shorts (listed below). Note that I’ve repurposed the article ‘a’ and the pronoun ‘I’, since they have very little value in problem-focused notes. The goal is to generate functional documentation with the fewest keystrokes, not flowing paragraphs.

Typing all lower-case is assumed but not required. Capitalization is only enforced for canonical abbreviations (HPI, ROS, RUQ, etc.) and certain keywords that are frequently missed (NO, NOT, LEFT, RIGHT).

Punctuation is optional and should be kept to a minimum. How much punctuation to add automatically is an unsettled issue. At this time I include colons when a list is expected and leading commas for certain phrases. This is subject to change.

I have an expanding number of disease and symptom shorts that are not listed here. Ultimately these may need to be specialty specific.

Finally certain phrases are included to support then needs of billing and compliance.

Patient Instructions Card with Advice on Common Problems

By •• Posted in Medicine, Patient Care

Patients who are actively engaged with their health have better outcomes. Good communication is key. I made this Patient Instructions Card about six months ago and have been very pleased with it. I’ve turned it into a generic PDF with custom name, phone and tobacco resource fields. Fill in your particulars and have it printed at 50% on card stock. Enjoy!

The front has lots of blank space to write on…

QuickHPI v1.2 – Fully Functional Client-Side Web App

By •• Posted in EMR, HPI, Teaching

This is the first release of quickHPI for general use by students, residents and clinicians. It is based on version 1.1 with persistent client-side data storage added. Once installed, it can be used offline when network connectivity is unavailable or undesired.

The purpose of quickHPI is threefold: 1) Provide a practical tool for clinicians; 2) Create a functional expression of the ideas presented here; and 3) Offer a self-directed learning tool for students and residents.

 

QuickHPI is both a tutorial and a practical tool for recording the History of Present Illness. As such it has wide applicability in medical education and patient care. The program instantiates my research into best practices for outpatient documentation aka The Rational History of Present Illness.

“Least Ink” Principal for Medical Documentation

By •• Posted in EMR

The best clinical documentation is that which gives to the reader the greatest amount of information in the shortest time with the fewest pixels.

Paraphrased from Edward R. Tufte
The Visual Display of Quantitative Information 

During April 2014 I gave a talk at an EMR meeting concerning the changes manifest in the everyday clinic note. Most are familiar with various approaches to generating notes that meet all requirements for billing, compliance, and liability. Patient care and physician efficiency frequently suffer. I am particularly concerned about “note bloat” and the tendency of automated systems to add noise and imprecision to medical documentation. I’ve been working with our EMR vendor to create a better approach to the History of Present Illness.

This week I launched the The Rational History of Present Illness project to develop and promote better documentation tools.

This is sample output from a template driven tool that does NOT attempt to generate english prose. For this hypothetical patient, the structured approach yields a complete HPI in 48 words and 290 characters (60 words if you count the labels). Also note the judicious use of directly typed input (in blue). One of the biggest problems I see with EMR templates is they over specify. Why check a box for a phrase that is sort of what you’re thinking when in a few words you can say precisely what you mean?! Now contemplate how easy it is to visually scan and assimilate the information. As Dr. Tufte would say, “there is very little Pfuff!” Least Ink in action!!

Atul Gawande “How do we heal medicine?”

By •• Posted in Medicine

Cowboys vs Pit Crews

Key facts from his recent TED talk…

  • Modern doctors have 4000 procedures and 6000 medications at their disposal
  • In 1970 it took 2 FTEs to care for a patient in the hospital
  • In 2001 it took 15 FTEs to care for the same patient
  • Checklists and mandatory pauses help decrease mistakes

“We are all specialists now, even primary care physicians.”

Atul Gawande “How do we heal medicine?” (video)

To sum up his talk in two words, both the Intensity and Complexity of care have increased in the past forty years. This is not surprising when you think about it. What aspect of life in the US has not become more intense and complex? He focuses on how the education of physicians lags behind the realities of team-based care. This is a valid point as far as it goes. He does not speculate on why “even primary care physicians” are specialists and no one is charged with understanding the entire spectrum of care for individual patients? (So I will…) In a word, Economics! During the 1990s Medicare and other payers decided to stop paying for coordination of care by primary care physicians. This was exacerbated by division of outpatient and inpatient care in the past ten years (again primarily for economic reasons). The new focus on high-volume, episodic care leaves little time for the big picture. This is not a flaw in medical education and not a choice made by primary care physicians! Merely the predictable consequence of decisions made by insurers and the federal government.

The Supreme Court and Healthcare Reform – Careful What You Wish For!

By •• Posted in Medicine

The US Supreme Court is about to hear arguments for and against the recent healthcare insurance reform law enacted by Congress. (aka The Affordable Care Act, aka Obamacare) At issue is the constitutionality of the individual mandate to buy health insurance. It is unclear whether they will set new precedent or rule on a much narrower basis. Their decision could have profound effects on the current law and future legislation. Partisans on both sides of this issue should welcome a broad decision and be ready to accept the consequences!

If the mandate is found to be constitutional, this strengthens the notion that private insurance has a significant role to play in our mixed healthcare system. It bolsters popular components of the law that limit insurance companies’ ability to deny coverage for pre-existing conditions, place lifetime caps on benefits, and allow young adult children to remain on their parents’ insurance. The real challenge—reining in the exploding costs of healthcare—is still ahead of us.

If the mandate is found to be unconstitutional, this is the best argument yet for a single payer system in the US. You cannot have a viable healthcare insurance system if a significant number of citizens have the ability to opt out when they’re young and healthy. Beware the law of unintended consequences! If it turns out to be unconstitutional to force broad participation in private insurance, can a public option be far behind? Careful what you wish for!

Update: Nice Summary of What’s at Stake on ProPublica!

July Update: Justice Roberts decided the mandate was actually a tax. So the law stands, but apparently this presages other limits to the Commerce Clause.

Approach to Cough Algorithm and Podcast

By •• Posted in Medicine, Podcast

I recently updated my lecture on cough, given to third-year medical students and residents. It presents an algorithm I developed based on the omnibus supplement published in the journal Chest and other sources. Here is a quick summary of key points that are often missed  by primary care physicians…

  1. Acute cough is largely due to viral infections and therefore antibiotics are NOT indicated.
  2. There is growing evidence that first generation antihistamines are the drugs of choice for undifferentiated acute cough.
  3. Post-infectious cough is the most common etiology for cough lasting between 3-8 weeks.
  4. Secondary causes of cough (reactive airways, GERD, post-nasal drip) should be considered based on symptoms and time course.
  5. In areas of high TB prevalence consider testing for active disease in any patient with a cough lasting more than two weeks (WHO recommendation).

I concise version of the lecture is available as a podcast.

The lecture handout is available in PDF format.

A Guide to Medical History Taking

By •• Posted in Medicine, Teaching

Always start with the standard questions applied to the patient’s Chief Concern(s): Location/Radiation; Quality/Severity; Duration (total/episode)/Frequency; Aggravating/Relieving Factors; Associated Symptoms/Effect on Function.

It is useful to think of the secondary history as a Focused Review of Systems (ROS). These questions often bring out information that supports a certain diagnosis or helps gauge the severity of the disorder. Unlike the primary history, a certain amount of interpretation (and experience) is necessary.

The tertiary history brings in elements of the Past Medical and Family History that have a bearing on the patient’s condition. By the time you get to the tertiary history you may already have a good idea of what might be going on. Read More…

Sick Around the World (PBS Frontline)

By •• Posted in Medicine

This is a great documentary from 2008 that explores how other wealthy countries deal with healthcare. The corespondent T.R. Reid visits five capitalist countries that provide affordable, nearly universal coverage for their citizens. How do they do it? He observes that here in the US we have the British model for veterans, the Taiwanese model for seniors, the German model for workers with insurance, but for the rest we are “just another poor country”. His conclusions…

1) Insurance companies must accept everyone, and cannot make a profit on basic care.

2) Everybody is mandated to buy insurance, with the government paying the premiums for the poor.

3) Doctors and hospitals have to accept one standard set of fixed prices.
