Global Health Care — an edX course

logo edX 2

So you think your health system is bad?  There are countries where doctors and nurses leave due to the risk of death (their own), countries where health care workers can’t make enough money to pay for their own hospital care, countries that don’t keep medical records, countries where doctors must see at least 100 patients per day and countries where a patient purchases the number of questions they want a doctor to ask — one question is typical — and at very low cost!

As the author of this blog I decided to try an online learning course from edX titled “Improving Global Health: Focusing on Quality and Safety” presented by faculty at Harvard.  Overall it is a good course.  I am sure everybody who takes the course finds different parts interesting depending on where they live and their background in health care quality and system organization.

Below are the things I found interesting from a US healthcare perspective:

  1. Errors and harm caused by health, especially in hospitals, is high everywhere.  The big categories are hospital acquired infections, adverse drug events, falls with injury, surgical complications, pressure ulcers and deep venous thrombosis.  Significant harm happens in about 10 to 15% of hospitalizations.  Errors in medical/surgical management are considered preventable.
  2. Countries have different standards of care.  And, countries have different legal systems.  The most interesting concept is to eliminate malpractice suits by having a compensation board and strong quality improvement.  Thus, patients get compensation much faster and the health care system improves to mitigate errors.  Accountability for errors becomes part of the quality improvement process, not the legal system.
  3. In most countries hospital and outpatient care seem to be in different silos, much to the detriment of patients who transition between the two.
  4. The PLAN-DO-STUDY-ACT cycle is critical to quality improvement.
  5. “If you can’t measure it, you can’t improve it“.  But, high tech and computerized methods are not always needed.  In low and middle income countries the use of simulated patients (in the US called secret shoppers) and text messaging questions by cell phone can collect hugely important data with a minimum of cost.
  6. Management practices of business in general are more effective than the business practices in healthcare.   The same principals apply and need to be followed.  For example, managers not meeting expectations need to be changed.  Just like measurements of healthcare quality there are measurements of business quality.  A culture of blame is a big problem.
  7. Patient-centered care is critically important.  There is a very strong statistical link between patients who feel their needs are being met and almost all other technical measures of quality.  Simply asking patients what they expect is a huge first step that is not being done my a majority of providers.  Dignity, respect and putting effort into meeting expectations is the essence of patient-centered care.  One measurement of patient-centered care is waiting time — waiting time for making an appointment, waiting time in an office, and waiting for surgery.
  8. Universal healthcare is highly desirable and some countries do a better job than others.  The key features are:  enrollment (signing up and getting a health card), universal coverage (the funds to pay for care — like insurance), and finally effective application of the coverage.  The last element is actually “quality” healthcare.  Having a health card is not enough.  Having insurance is not enough. Effective care is a combination of prevention (population-centered) and patient-centered care within the financial constraints of a system.
  9. Politics is present in all forms of health care.  But, the focus for patients, providers and the news media should be on the gap between care that is reasonably possible and care that is actually delivered.

U.S. Malpractice System is a Failure

Cut the ribbon

The U.S. tort system as a solution to compensation for medical errors is an abysmal failure.   It’s unfair to doctors and  it’s unfair to patients.

Here are a few statistics to make the point:

  • Every year 400,000 patients are killed by medical errors and even more are injured.  But, less than 2% receive compensation through suits.  98% never file suits.
  • 80% of suits against doctors fail.
  • 50% of compensation awards are paid to lawyers.
  • The average time from filing suit to winning compensation is 3.5 years.

The practice of “defensive medicine” is well known.  The fear of suits has caused many doctors to order more tests than are necessary.  Even the AMA estimates the unnecessary tests cost between $84 and $151 billion each year.  Worse yet is the effect on medical records:  doctors make records “look good in court” by leaving out embarrassing details — making the job of quality improvement much more difficult.

There can be no other conclusion:  the U.S. justice system is incapable of providing compensation to the vast numbers of injured patients and it stands in the way of quality improvement.

Other countries have much better systems.  One that really stands out is Finland.  They have separated compensation from accountability and quality improvement.  Compensation is decided by a compensation board — compensation is often paid in as little as 2 weeks.  Physicians can readily admit an error and say “I’m sorry” and go a step further and actually help patients get compensation.  

The Fins have a strong quality improvement program which can change the medical system that allows errors to happen and force practice changes as needed — the primary goal is to reduce errors, not to punish doctors (except for criminal behavior). 

The money spent in the  U.S. for malpractice insurance both by doctors and hospitals, and the fees for lawyers would be much better spent in a compensation system like Finland.  Current efforts at U.S. “tort reform” are aimed at reducing suits and thus reducing compensation.  The suits remain unfair to doctors and inadequate to serve injured patients.  “Tort reform” should be changed to “tort elimination” then replaced with a compensation board type system.

This is an excellent time to change the tort system because the U.S. is on the verge of universal health insurance.  The question of who will pay the cost of health care error  is “insurance” rather than bankruptcy court.  By setting up a compensation system more attention can be directed to fair compensation and much stronger quality improvement.

Ebola concern — the CNN and Fox crisis

touching

It’s difficult to understand how one person coming to the U.S. with Ebola constitutes a crisis.  The 75,000 patients per year that die of hospital acquired infections looks more like a crisis.  The 443,000 deaths per year related to smoking is clearly a crisis.  CNN and Fox news seem to be able to stir panic with constant “we’re all going to die” mentality.  The most helpful suggestion from the media is to quarantine Texas.

Helene Cooper of the New York Times was featured on PBS 10/19/2014.  She recently returned from a reporting trip to Liberia where she concluded Liberians show less panic than people in the U.S. She attributes this to Liberian’s having a better understanding of how the disease is transmitted.  The observation rings true since most US news reporting does not attempt to educate, just analyze incomplete information.  When this is all over congress will owe CDC director Dr. Thomas Frieden a massive apology for their rabid questioning … do they ever apologize?

The disease is transmitted by bodily fluids, usually by touching a person (see picture) with symptoms (vomiting, diarrhea and fever) or touching their secretions.  In Liberia the population avoids touching each other.  But, the real risk is for healthcare workers — because people with symptoms go to the hospital.  The patient who came from Liberia with the disease died in a Dallas hospital but his fiancé and other people he lived with did not get sick!  It is the nurses who are at risk and two of them (so far) have contracted the illness.

It’s good to hear the U.S. military is erecting mobile hospitals in West Africa — hopefully more countries will help.

Critical Communication — SBAR

submarineThe U.S. Navy Submarine Service is attributed with the development of a communication technique for critical situations.  The technique is to standardize a message from one person to another in the order of Situation, Background, Assessment and Recommendation.  For example in a submarine:

  • Situation:  Captain this is #1, we are having difficulty maintaining our speed
  • Background:  We are near a fishing fleet
  • Assessment:  I think we may be entangled in a fishing net
  • Recommendation:  I recommend we surface and cut away the netting

The captain says “make it so” or perhaps he says “no, all stop, send out divers”

 

About 15 years ago the method came to the attention of patient safety experts.  It had several great features:  1) The person on the front line (like an ER doctor or nurse) could make a report quickly  2) the method was easy to learn and was consistent even when emotions were running high  3) It leveled the hierarchy so the person on the front line made a recommendation with situational awareness that the person receiving the message might not have.  In a medical situation SBAR might sound like:

  • Situation:  Doctor this is the ICU nurse, your patient John Doe has become comatose and is breathing very slowly.
  • Background:  He has lung disease and was just admitted 2 hours ago
  • Assessment:  I think he is in respiratory failure
  • Recommendation:  I recommend we intubate as soon as possible.

The critical care doctor says: “Get me a scope and a tube, I will be right there”

 

Those health care professionals who embraced the method found it very helpful and it is still being used at many institutions.  But, the idea has not had universal success for reasons that were not clear at the outset:

  1. Fear.  Recommendations might be rejected.
  2. License:  Some felt their license did not allow an assessment which was the equivalent of a diagnosis.
  3. Semantics:  The word assessment means physical exam to nurses but it means diagnosis to physicians.
  4. Litigation risk:  Some felt if a recommendation was followed and later proved to be an error they would be blamed and possibly sued.

 

Improved communication in critical health care situations is very important to the patient in distress, in fact, poor communication is responsible for many in-hospital errors.  The SBAR technique is more difficult that one might think.  And, implementing it requires more than just saying “wow, this is great, do it”.  Techniques for implementation include some of the following:

  1. Audio or video recordings of the technique in use
  2. Practice sessions including both doctors and nurses.
  3. Role playing — the doctor giving the nurse a report and visa versa.
  4. Explanation of why the technique works
  5. Examples of errors in communication and how patients might suffer
  6. Emphasis on teamwork and not blame.  A single negative comment by a physician or supervisor can take a great deal of effort to correct.
  7. Understand a critical assessment is not a final diagnosis but just a step in the right direction.  The assessment is made at the training level of the person stating it.  Some might say “breathing difficulty” some might say “respiratory failure”.
  8. Continued education and reinforcement.  All new members of a medical team need to be instructed.  This is an ongoing process.

 

Good communication improves patient safety especially when quick action is needed.  SBAR is a framework for communication.  Other methods may do the same thing but the history and success so far suggest it has wide applicability.  Users of the technique express satisfaction (1).  Communication always involves two parties — both must be accepting and well trained to use the technique.  The World Health Organization has included SBAR in some of its publications (2) so wider use of the technique is expected.

Hospital Re-admission — do phone calls help?

Jphoneust calling a patient on the phone does not prevent patients from being re-admitted!

Hospitals are very interested in preventing a patient from returning to the hospital (called a re-admission) within 30 days from discharge due to the financial penalties from Medicare.

For example, if a patient is hospitalized with a serious problem called congestive heart failure (fluid retention that causes shortness of breath) the hospital will be penalized financially if the patient gets the condition all over again and has to return.

The government idea is to force hospitals to be more accountable – it’s like a 30 day guarantee from an auto repair shop!  So hospitals are looking for ways to improve their performance (and avoid paying money).

There is no question frequent visits to a physician can reduce re-hospitalizations.  However, a recent hospital study found that hospital nurses who talked to patients before discharge and who called them after discharge did not help the readmission problem — if fact there were more re-admissions!

a)  How can this be?

b) Do well meaning nurses actually make the problem worse?

c) Does this mean hospitals should not be penalized?

The answers are: a) bad science b) yes  and c) no, perhaps they should be penalized more!

The “bad science” part is because there was no intervention to adjust medications or treatments that might prevent readmission.   A hospital nurse only has one option for a telephone  intervention:  “you better get checked at the ER”.  The conclusion from the study should have been stated “chatting with a patient does not prevent re-admission” — brilliant deduction.

The outpatient care provider’s  office is where action can be taken to stop re-admissions.  That’s where medications can be prescribed.  If the hospital wanted to prevent re-admissions they should have made an appointment and given the patient a coupon for a taxi ride to and from the outpatient office.   This is not rocket science.

Hippocrates — the missing duty

hippocratesHippocrates missed something big — a doctor’s responsibility to improve the care of other doctors.  OK he did get some things right — here are his points from the 5th century BC:

  • use good judgement — nice
  • revere your teachers — nice if you are a teacher
  • order a good diet — still a matter of question
  • don’t hurt or damage people — really or just statistically?
  • don’t poison people — makes sense to me
  • comport oneself in a Godly manner — doctors have no problem here
  • don’t do surgery if you don’t know how — duh
  • doctor visits should be for the advantage of the patient — patient centered care is nothing new
  • keep medical information private — HIPPA before its time

Doctors often take some revised or modernized version of the Hippocratic Oath.  Sadly, the idea that doctors have some responsibility for the care provided by other doctors is missing.  The idea is front-and-center in most work on quality improvement — where the idea is indeed to improve everybody’s care.  Doctors should have 2 responsibilities:  1) care for the patient and 2) improve the quality of care for all.

Most doctors don’t accept item #2, instead the list is:  1) care for the patient and 2) care for personal finances.  In essence, doctors shun quality improvement because “I’m not paid to do that”.

How many doctors participate in quality improvement activities?  Meaning, find a problem, make a plan,  do something, study the result, then act to improve the plan and repeat the cycle.  This is not rocket science.  A physician is not expected to do molecular biology research in the office but there is an expectation they will improve waiting time and reduce prescribing errors — things easily within their grasp.  How many physicians have a quality improvement meeting each morning or at least once a week — I dare say less than 1%.

Systems of care are very important.  But, the lack of physician involvement in quality improvement is a serious deficiency in many health care systems.  In some respects this is a structural issue for health care — it’s not a process, and it’s not an outcome.  It’s like a foundation for a house — no foundation means the house will not last.

Hidden Healthcare Capacity — learn from lean manufacturing

conveyorbeltHealthcare in the past has shunned “conveyor-belt” surgery, “cookie cutter” treatments and “cookbook medicine”.  But, the disdain for efficiency, as honed by manufacturing, has put the spotlight on medicine and surgery as very inefficient with a huge hidden or wasted capacity.  Patients and healthcare providers are asking for the training of more healthcare professionals — they can’t manage the wave of baby-boomers needing care or the influx of new patients using the methods of the past.   So, let’s not use the methods of the past, it’s time to learn from industry, from Toyota, from Ford.
The key principle is “lean” —  definition of Lean, as developed by the National Institute of Standards and Technology Manufacturing Extension Partnership’s Lean Network:

“A systematic approach to identifying and eliminating waste through continuous improvement, flowing the product at the pull of the customer in pursuit of perfection.” 

Here is a translation for healthcare:

“A systematic approach to identifying and eliminating waste through continuous improvement, providing health care as needed by the patient in pursuit of perfection.”

 Here are the 8 “wastes” to be eliminated, as might be applied to a medical office:

  • Overproduction — From a medical office standpoint this is excess staff at certain times — indicated by an appointment schedule that is not full.  Staffing must be adjusted to patient load.
  • Waiting — Patients waiting for appointments, providers waiting for test results.  Ideally the when patient arrives  the provider is ready to begin.  Needs to be monitored with visual controls all the time.  Solving patient problems on the phone prevents clogging the system with unnecessary visits and reduces excess inventory.
  • Transportation — equipment (like gowns and syringes) need to be at the point of use not transported around the office.
  • Non-Value-Added-Processing (reworking) — having to review patient data because the problem was not resolved initially.  Sometimes multiple workers collecting the same information (very common when patients are admitted to the hospital) And, excessive medical documentation, a common problem with speech to text systems.
  • Excess Inventory —  No room in the appointment schedule because it is all filled up, patients want to be seen but no staff are available.  Represents a failure to hire adequate providers and staff.  Larger organizations are better able to make staff flexible, like sending them to a branch office if several staff are missing due to vacations or illness.
  • Defects (do it right the first time) — Following evidence based guidelines and using checklists reduces error in treatment and diagnosis.  Errors may result in legal action.  But, less severe errors end up requiring correction or at least explanation.
  • Excess Motion (poor workflow and documentation) A huge problem.  If offices don’t have labs, x-ray, a pharmacy, physical therapy, and commonly needed specialists it causes wasted patient and staff time.
  • Underutilized People — offices don’t often let nurses or scheduling departments make common sense changes.  Small offices fail to hire computer consultants or patient educators.

Much of the waste currently is due to lack of scale for many providers — they just don’t have big enough facilities.  Also, on a larger scale many towns have excess capacity in certain specialties.  Like supporting one neurosurgeon when all the neurosurgery should be done at a regional center to keep the providers busy and competent.  Likewise, not every hospital should be a high level trauma center.  Not every town or hospital needs a cancer treatment center.

Simply treating more patients over the phone is probably the greatest method to find hidden capacity.  If a visit is just to consider a blood sugar record that can be done without an office visit.  The second best efficiency boost is to incorporate NPs and PAs as team members.  Third, a high functioning computer record helps to prevent reworking and reduces excess motion.  Above all, constant monitoring of efficiency and quality with continuous improvement is essential.
