Clinical Quality, Medication reconciliation

Medication reconciliation form -A Patient safety Net

Medication reconciliation

The goal of medication reconciliation is to provide correct medications to the patient at all transition points within the hospital and at discharge. At every transition point, a nurse must review previous medication orders with new orders to reconcile differences to help eliminate medication errors. Poor communication of a patient’s medical information at transition points results in medication errors and adverse drug events.

JCAHO Requirements

According to the JCAHO National patient safety goals, accurately and completely reconciling medications across the continuum of care is an important patienty safety goal. It is important to recognize that sound system design is intrinsic to the delivery of safe, high quality health care, the goals generally focus on system-wide solutions, wherever possible.

Med Rec Form

Using a standardized medication reconciliation form, the nurse can completely reconcile medications and obtain other information that can improve patient safety. Consequently, the physician will have an organized document with current information at hand to reconcile. The nurse can them compare the list against the physician’s admission, transfer, and/or discharge orders. this form was created to obtain an accurate list of all medications (prescriptions, over-the-counter, supplements, herbals, etc.) taken by the patient at home prior to out-patient or in-patient admission. This includes the drug name, dosage, frequency and route.

Clinical Quality, Critical Care

Reduce ICU Length of Stay by goal setting

In my previous article on Critical care or Intensive care(The link betweek efficiency and patient safety), we saw how efficiency can impact patient safety and thereby the outcome. Now let us examine a recent innovation in the area of critical care that has actually accomplished this at the John’s Hopkins Hospital, Baltimore,MD.

The Problem

Poor and inconsistent communication among providers in the intensive care unit (ICU) can lead to a lack of understanding of daily goals and the failure to deliver needed services that accelerate recovery and discharge.
ICU patients tend to have life-threatening problems and complex care needs that require a combination of many treatments and services in order to achieve timely recovery and discharge.
Lack of communication among providers can lead to a lack of understanding about what needs to occur each day in the ICU.
The net result is that patients remain in the ICU longer than necessary, and are at greater risk of harm, including morbidities and mortality.

The Solution

The ICU care team (which includes the attending physician and/or fellow, anesthesia and surgery residents, a nurse practitioner, a nurse, and a pharmacist) visits each ICU patient every day between 20 and 25 minutes and uses the ICU Daily Goals Form to document the This creates a standardized way to communicate with one another and a focussed plan of care.

Expected Benefits

The benefit of this innovation may be greatest with high-intensity patients, such as those in the ICU. It also may be most applicable in academic medical centers and other organizations where ICU care is provided by many different types of practitioners.
Reduced LOS – At Johns Hopkins where this innovation was pioneered, the mean length of stay in the ICU reduced from 2.2 days to 1.1 days

Clinical Quality

Using Efficiency to improve Quality of care

Treatment of Community Acquired Pneumonia

According to the American Academy of family Physicians, there are 5.6 million cases of Community-acquired pneumonia annually in the US. The cost of treatment and care for CAP is an estimated $8.4 billion. The type of management and treatment of CAP and outcomes can significantly influence the cost of care and outcomes for hospitals.

Streamlining the workflow

University of Kentucky Medical Center(featured in the video) clearly shows how hospitals can save significant amount of time, costs and improve patient care by analyzing workflows.

Streamlining the drug preparation and administration process for CAP

By studying the process(time taken to process one order of an IV antibiotic ad mixture) they have observed that it takes approximately 16:42 minutes to prepare and administer the (Nursing + Pharmacy time). So from an efficiency standpoint it makes sense reduce or completely eliminate steps involved in drug preparation and have fewer administrations.

Efficient method of drug administration

Choosing monotherapy instead of combination therapy reduces the number of steps.Using agents with longer half-lives allows for once-daily administration, which in turn leads to improved compliance and outcomes and decreased costs. In addition, transitioning patients to oral therapy as soon as they are clinically stable can significantly reduce the length of hospitalization-the major contributing factor to health care costs.

University of Kentucky Medical Center applied this and reduced the time to prepare and administer Pre-mix doses of Monotherapy to 3:26 minutes

Emergency Care

10 Best practices for Emergency Departments

Macro Trends in Emergency Care

According to the Center for Disease Control, the number of ED visits increased from about 96.5 million to 115.3 million in the United States from 1995 to 2005. This amounts to a sharp 20% increase. While this happened, the number of EDs themselves dropped from 4,176 to 3,795. With 219 ED visits per minute in the US during 2005, the ED overcrowding problem has slowly become a nationwide phenomenon. And like with other macro trends, this will replicate itself in other countries as well (if it has not already). In the fastest developing economies (like India and China), this might come sooner than expected. We will examine this and other ED practice trends in future articles. But for now, let us see what some of the best Emergency departments have been doing.

Slicing the Volume Pie

Best practice EDs address the ED overcrowding problem in 3 steps. Seperating out the flow of Urgent vs Semi urgent and Non urgent is the first step in improving flow as over 33% of the patient traffic in EDs is usually of a semi urgent or non urgent type according to the National Hospital and Ambulatory Medical Care survey. Identifying strategies to then take care of these patients in a timely manner is the second step.Setting up efficient Admitting and discharging mechanisms is the third step.

Critical Care

The link between efficiency and patient safety in the ICU

Over a year approximately five million people recieve Intensive care in the United States. In hospitals we refer refer to these patients as ‘critical care’. While the ICU in most hospitals is perhaps the most well run unit from a patient safety standpoint. There is still room for improvement from an efficiency standpoint. And if we increase efficiency we can greatly affect clinical outcomes and paitent safety.

Now wait a minute, how is that possible. Isn’t efficiency about financial dollars for the hospital and something about working like Toyota or GE. What has it got to do with patient care, safety and clinical outcomes ? Ok, let us look at some facts and you can decide for yourself.

Facts from America’s ICUs

The average length of stay in an ICU unit is 4 days
Average number of Critical care/ICU patients per day is 90,000
The average survival rate is 86%

You might say 86% is not bad, and infact its a good outcome in most clinical areas. But consider these facts,

Infections are the main cause for fatality in critical care
4% of all patients contract line infections after 10 days
After 10 days with a catheter 4% of patients (in the US) develop bladder infections
After 10 days on a ventilator 6% develop penumonia and 40-50% of cases result in death

In other words, as length of stay increases (which is an important efficiency metric) the chances of survival reduce greatly. Ok now, let us consider the costs.

On average ICU patients occupy 10% of total beds in the US
On average ICU beds account for 30% of an acute care hospital cost in the US
The total cost of critical care is $180 billion in the US

I hope I have made a case for improvements in the ICU.

Surgery

Innovative strategies in Surgery Scheduling

Silo view of scheduling in hospitals

A traditional view of scheduling in surgical services is that, its a function that helps manage operating rooms and procedures. Its viewed as a value added service that a hospital or Ambulatory center provides for surgeon offices, to help organize the date and time, and location of a surgical procedure. This is a silo view of scheduling. It’s importance is largely underplayed and often overridden by management decisions. For instance, it is common for surgeons to complain to a senior executive (often a VP or the president) that they are not getting their preferred surgery date and/or time. If this happens after the next day’s surgery schedule production, it becomes an Add on or depending on the medical need an Emergency surgery. In such situations, the executive calls the scheduling office and asks them to accomodate the request in order to provide good service. Grudgingly, the schedulers relent. But at the cost of bumping another case, which eventually means more Add ons. If this procedure requires the patient to be admitted to an inpatient bed, then it affects bed management since they had not planned for this. Eventually, everyone from the Emergency department to the Inpatient units and PACU faces long wait times for bed assignment. This can add significant time to the patient’s length of stay, affecting quality, customer services while adding significant cost to the hospital. So a seemingly noble gesture by an executive can often times have an adverse ripple effect on the overall efficiency of the hospital. Some scheduling departments even use advanced Information technology products and decision support systems to function. In which case, they become island’s of mechanization.

A new perspective for Scheduling

What we need to understand is that scheduling is a key driver of operational efficiency in the surgery department and the rest of the hospital. And therefore, we have to apply systemic thinking (you may refer to my previous post for more on this). It is very important to assess the downstream impact of all decisions while making changes to the schedule. Now, let us look at how we can solve this problem.Since, there is no one size fits all solution, I will present several strategies for problems. These strategies are drawn from best practice research, implementation done in several large surgery departments and smaller Ambulatory centers nationwide.

Block time release

Begin releasing most service line block time in advance(ideally between 4 days to week depending on your size and volume). This allows adequate lead-time for surgeons to schedule additonal cases, and will significantly reduce ‘gaps’ in your schedule.

Urgent/Emergent Room

Hold atleast one room in the OR for Emergent and Urgent cases.The idea is to clearly separate out your urgent/emergent cases from the electives. While it may seem counter intuitive, this has helped ORs significantly increase case volumes and reduce overtime.

Add On analysis and Add On Room

Just like with Emergency your Add On might be seriously impairing you ability to have a flexible yet efficient schedule. But the good news is unlike urgent cases, you will be able to predict Add ons better than you think. Review, your Add On volume for the most recent 3 months and you will see your ‘peaks and valleys’. Asses, utilization of your rooms, equipment and staff.This again helps reduce overtime significantly and increase your ability to take more cases.

Case Length Accuracy- Schedule Reliability

In a majority of ORs the schedule is not reliable due to inaccurate prediction of case time.Which means actual case length and scheduled case length do not match. Use average procedure and surgeon specific case length for scheduling. (includes typical case specific cleanup and room preparation time).

Costing out gaps in the OR schedule

Calculating what is gained or lost in terms of revenue,staff time and quality of care before implementing scheduling changes, is a good way to assess the full success of these improvements. In many cases, this has been used to get management buy-in and support from physicians

A brief history of systemic thinking

From Common Sense to Systemic thinking

Most of the basic goals of systemic thinking are common sense and documented examples can be seen back to at least Benjamin Franklin. Poor Richard’s Almanack says of wasted time, “He that idly loses 5s. [shillings] worth of time, loses 5s., and might as prudently throw 5s. into the river.” He added that avoiding unnecessary costs could be more profitable than increasing sales: “A penny saved is two pence clear. A pin a-day is a groat a-year. Save and have.”

Again Franklin’s The Way to Wealth says the following about carrying unnecessary inventory. “You call them goods; but, if you do not take care, they will prove evils to some of you. You expect they will be sold cheap, and, perhaps, they may [be bought] for less than they cost; but, if you have no occasion for them, they must be dear to you. Remember what Poor Richard says, ‘Buy what thou hast no need of, and ere long thou shalt sell thy necessaries.’ In another place he says, ‘Many have been ruined by buying good penny worths’.” Henry Ford cited Franklin as a major influence on his own business practices, which included Just-in-time manufacturing.

The concept of waste being built into jobs and then taken for granted was noticed by motion efficiency expert Frank Gilbreth, who saw that masons bent over to pick up bricks from the ground. The bricklayer was therefore lowering and raising his entire upper body to get a 5 pound (2.3 kg) brick but this inefficiency had been built into the job through long practice. Introduction of a non-stooping scaffold, which delivered the bricks at waist level, allowed masons to work about three times as quickly, and with less effort.

Birth of Scientific Management

Frederick Winslow Taylor, the father of scientific management, introduced what are now called standardization and best practice deployment: “And whenever a workman proposes an improvement, it should be the policy of the management to make a careful analysis of the new method, and if necessary conduct a series of experiments to determine accurately the relative merit of the new suggestion and of the old standard. And whenever the new method is found to be markedly superior to the old, it should be adopted as the standard for the whole establishment” (Principles of Scientific Management, 1911).

Taylor also warned explicitly against cutting piece rates (or, by implication, cutting wages or discharging workers) when efficiency improvements reduce the need for raw labor: “…after a workman has had the price per piece of the work he is doing lowered two or three times as a result of his having worked harder and increased his output, he is likely entirely to lose sight of his employer’s side of the case and become imbued with a grim determination to have no more cuts if soldiering [marking time, just doing what he is told] can prevent it.” This is now a foundation of lean manufacturing, because it is obvious that workers will not drive improvements they think will put them out of work. Shigeo Shingo, the best-known exponent of single-minute exchange of die (SMED) and error-proofing or poka-yoke, cites Principles of Scientific Management as his inspiration (Andrew Dillon, translator, 1987. The Sayings of Shigeo Shingo: Key Strategies for Plant Improvement).

American industrialists recognized the threat of cheap offshore labor to American workers during the 1910s, and explicitly stated the goal of what is now called lean manufacturing as a countermeasure. Henry Towne, past President of the American Society of Mechanical Engineers, wrote in the Foreword to Frederick Winslow Taylor’s Shop Management (1911), “We are justly proud of the high wage rates which prevail throughout our country, and jealous of any interference with them by the products of the cheaper labor of other countries. To maintain this condition, to strengthen our control of home markets, and, above all, to broaden our opportunities in foreign markets where we must compete with the products of other industrial nations, we should welcome and encourage every influence tending to increase the efficiency of our productive processes.”

Ford inspires new thinking

As hard as it is to believe,(since most people think of Toyota when then think of innovation in the auto industry today) it was Dertroit auto maker Ford that inspired a whole new way of thinking about processes. Largely, credited for popularizing the ‘assembly line’, Henry Ford continued this focus on waste while developing his mass assembly manufacturing system. “Ford’s success has startled the country, almost the world, financially, industrially, mechanically. It exhibits in higher degree than most persons would have thought possible the seemingly contradictory requirements of true efficiency, which are: constant increase of quality, great increase of pay to the workers, repeated reduction in cost to the consumer. And with these appears, as at once cause and effect, an absolutely incredible enlargement of output reaching something like one hundredfold in less than ten years, and an enormous profit to the manufacturer”.

Ford (1922, My Life and Work) provided a single-paragraph description that encompasses the entire concept of waste. “I believe that the average farmer puts to a really useful purpose only about 5%. of the energy he expends. … Not only is everything done by hand, but seldom is a thought given to a logical arrangement. A farmer doing his chores will walk up and down a rickety ladder a dozen times. He will carry water for years instead of putting in a few lengths of pipe. His whole idea, when there is extra work to do, is to hire extra men. He thinks of putting money into improvements as an expense. … It is waste motion— waste effort— that makes farm prices high and profits low.” Poor arrangement of the workplace– a major focus of the modern kaizen– and doing a job inefficiently out of habit– are major forms of waste even in modern workplaces.

Ford also pointed out how easy it was to overlook material waste. As described by Harry Bennett, “One day when Mr. Ford and I were together he spotted some rust in the slag that ballasted the right of way of the D. T. & I [railroad]. This slag had been dumped there from our own furnaces. ‘You know,’ Mr. Ford said to me, ‘there’s iron in that slag. You make the crane crews who put it out there sort it over, and take it back to the plant.’” In other words, Ford saw the rust and realized that the steel plant was not recovering all of the iron.

Design for Manufacture (DFM) also is a Ford concept. Per My Life and Work, “Start with an article that suits and then study to find some way of eliminating the entirely useless parts. This applies to everything— a shoe, a dress, a house, a piece of machinery, a railroad, a steamship, an airplane. As we cut out useless parts and simplify necessary ones, we also cut down the cost of making. …But also it is to be remembered that all the parts are designed so that they can be most easily made.” The same reference describes Just in time manufacturing very explicitly.

While Ford is renowned for his production line it is often not recognized how much effort he put into removing the ‘fitters’ work in order to make the production line possible. Until Ford a car’s components always had to be ‘fitted’ or reshaped by a skilled engineer at the point of use so that they would connect properly. By enforcing very strict specification and quality criteria on component manufacture he eliminated this work almost entirely, this reduced manufacturing effort by between 60-90%. However Ford’s mass production system failed to incorporate the notion of “Pull” and thus often suffered from over production.

The rise of the ‘Toyota way’ of thinking

Toyota’s development of ideas that later became Lean may have started at the turn of the 20th century with Sakichi Toyoda in their textile business with looms that stopped themselves when a thread broke, this became the seed of “Autonomation” and “Jidoka“. Toyota’s journey with JIT may have started back in 1934 when it moved from textiles to produce its first car. Kiichiro Toyoda, founder of Toyota Motor Corp., directed the engine casting work and discovered many problems in their manufacture. He decided he must stop the repairing of poor quality by intense study of each stage of the process. In 1936 Toyota won its first truck contract with the Japanese government his processes hit new problems and developed the “Kaizen” improvement teams.

Levels of demand in the Post War economy of Japan were low and the focus of mass production on lowest cost per item via economies of scale therefore had little application. Having visited and seen supermarkets in the US Taiichi Ohno recognised the scheduling of work should not be driven by sales or production targets but by actual sales. Given the financial situation during this period over-production was not an option and thus the notion of Pull (build to order rather than target driven Push) came to underpin production scheduling.

It was with Taiichi Ohno at Toyota that these themes came together. He built on the already existing internal schools of thought and spread its breadth and use into what has now become the Toyota Production System (TPS). It is principally from the TPS, but now including many other sources, that Lean production is developing. Norman Bodek wrote the following in his foreword to a reprint of Ford’s (1926) Today and Tomorrow: “I was first introduced to the concepts of just-in-time (JIT) and the Toyota production system in 1980. Subsequently I had the opportunity to witness its actual application at Toyota on one of our numerous Japanese study missions. There I met Mr. Taiichi Ohno, the system’s creator. When bombarded with questions from our group on what inspired his thinking, he just laughed and said he learned it all from Henry Ford’s book.” It is the scale, rigour and continuous learning aspects of the TPS which have made it a core of Lean
