Let’s Not Kid Ourselves

At this point, many of us are posing the rhetorical query, “How much does obesity cost the overall economy, anyway?” This sounds like a trick question, one posed not to extract a factual answer, but to take an indirect route toward confrontation with a really unpopular conclusion. It sounds this way because it is.

One reason the question is virtually unanswerable is, the price of each separate factor involved in bariatric medicine continues to rise. Another reason is that even with modern lightning-speed communication, it is still pretty difficult to guarantee that a pile of information about anything is the latest and greatest.

In many cases, multiple factors change too quickly to be meticulously tracked and compensated for. Sometimes, even experts review their work or the work of others and conclude that “Oops! Those numbers are on the wacky side.” We can take a snapshot that captures a moment in time and compare it to another snapshot in a later or earlier time frame, or in the same moment but in a different place.

A considerable fraction

Back in 2015, the management consulting firm McKinsey Global Institute announced that almost one-third of Earth’s population, or 2.1 billion people, were overweight or obese. In developed economies, “about 15 percent of health care costs […] are driven by [obesity].” Moneyweb.co.za noted that “healthcare costs are more than 40% higher for obese patients than normal-weight patients.”

The investment advice website added that the global impact of obesity was estimated to be “on a par with the impacts of smoking or armed violence, war and terrorism.” Expressed numerically, this figure amounted to around $2 trillion, or 2.8% of the global Gross Domestic Product. As the saying goes, “no matter how you slice it,” this was a real wake-up call. To put the icing on the cake, McKinsey issued the understatement of the century, namely, that “global disagreement on how to move forward is hurting progress.”

Some widespread misunderstandings

In the same year, a mere decade ago, Dr. Bruce Y. Lee compiled a list of seven myths that conspired to convince employers that they could safely ignore the encroaching threat of obesity — the first one being that obesity did not exist in their particular line of work. But in truth, few businesses were found to be exempt. While relatively few responsible authorities were paying attention, obesity had snuck into “nearly every country, income level, race, ethnicity and age group.”

Rising obesity rates were not random accidents, but established facts of life. Even if one particular corner of a commercial field had not yet been invaded, suppliers, subsidiaries, and other connected areas would be affected. And to simply hire skinny people was no solution, because the possibility that they could balloon up was always lurking.

The second prevalent myth was that obesity invariably sprang from each employee’s individual lifestyle choices. But the author pointed out how mistaken a boss would be to assume that anyone who put on pounds was simply lazy or lacking in self-control. To assume that everyone just needed to eat less and exercise more would be a serious error in judgment. People in positions of authority were urged to remember that behavior is governed by “a number of social, environmental, cultural, and financial factors,” which will be looked at in the next installment.

The Devil Is in the Details

The most recent installment of this series focusing on the cost of obesity mentioned smart beds that can track patients’ vital signs, weight, and other factors.

It also mentioned a complex issue with which hospitals never cease to struggle: guaranteeing the correct amount of any medication to precisely fulfill the requirements of the patient’s body and condition. This obviously is of crucial importance not only to the clinically obese patient but to each and every patient. Meticulousness in this area is necessary for everyone from the pre-born infant to the geriatric patient who (where legal) opts for an assisted demise.

In the domain of medication, so much can go wrong. It must be the right medication, untainted, and within its use-by date. For numerous reasons, including public safety and legal liability, all the documentation has to be correct, and strictly accounted for. Substances need to be shipped and stored correctly. All communication regarding administration must be clear, accurate, timely, and easily accessible.

And of course, as already emphasized, the necessary factors include…

[…] a current, accurate weight instead of relying on a historical, stated, or estimated weight; and obtaining, documenting, and communicating patient weights in metric units only (i.e., grams or kilograms). Key patient information used to guide appropriate medication therapy includes age, weight, height, allergies, diagnoses, laboratory values, and vital signs…

The very explicit Pennsylvania Patient Safety Advisory is a good example of the thorough inclusion of multiple factors involved in risk reduction, like equipment cost, and its upkeep and repair cost, and the expense of training people to use it correctly. It comes as no surprise to see accurate weighing equipment at the top of the list, as always. As we have mentioned, such hardware includes “floor scales, stretchers and beds with built-in scales, and standing, chair, and wheelchair scales.”

The personnel who employ these devices are expected to be familiar with the manufacturers’ recommendations for keeping them accurately calibrated, lubricated, titrated, or whatever. And despite the USA’s stubborn refusal to join the world in using the metric system for general purposes, it must be employed in the realm of weights and measures having to do with humans and medications.

One important factor discussed by this document is that of organizational expectations. Specifically, the best practice is to specify and assume that…

[…] obtaining the patient’s actual weight is part of the mandatory nursing assessment and reweighing of the patient occurs as warranted, based on patient’s clinical condition. Consider requiring reassessment of a patient’s weight when initiating or changing the dose of weight-based medications, clinical situations in which weight fluctuations are expected, or situations in which a weight variation may impact the course of care.

In other words, stay on top of this factor. Even in situations where it may not seem very important, documentation creates reality. As more attention is paid to the phenomenon of weight fluctuation in patients, more factual information will accumulate and reveal its significance, for the good of future patients.

It is also recommended to pay meticulous attention to this factor, other than in the midst of an emergency, of course. And for goodness’ sake, be sure all pertinent weight stats are recorded clearly, and in a quickly findable location, in the patient records. The document contains even more suggestions about the administration and implementation of weight-related policies, and about sketching out contingency plans in advance.

Weight is one of the easiest variables to keep track of in a clinical setting, especially with the newest specially developed or adapted equipment. The weight factor’s ubiquity and banality place it in danger of being overlooked and undervalued, but excellent arguments can be made for paying meticulous attention to this issue.

Smart Beds — for Bariatric and Other Reasons

In the field of bariatrics, it seems obvious that heavy people face physical challenges and restrictions that can require some pretty elaborate equipment. It is also apparent that ever more complicated hardware must and will inexorably raise the total cost of healthcare. But obese people should not be assigned the whole blame. Increasingly, medical equipment related to weight is for everyone.

We spoke of the transfer safety factor, with an uncomfortable number of mishaps, resulting in what are somewhat euphemistically called “delays in care.” Moreover, for hospital inpatients of many sorts, continuous weight monitoring is increasingly seen as essential.

A company called SonderCare explains why:

A bed equipped with load sensors provides real-time information that derives from, and in turn affects, the patient. Treatment options can change minute-by-minute, rather [than] according to orders tied to an 8-hour shift.

Despite the best intentions of staff members, the big danger point connected with patient injuries is movement from place to place. If the patient can just stay right there in bed and be weighed, so much the better, because a potential cause of injury has been eliminated.

In this style of bed, load sensors convert the pressure they feel into electrical signals for crucial weight monitoring, while other technology includes keeping track of the patient’s vital signs. A sudden weight change, either up or down, may indicate a problem with the heart or kidneys, and can be quickly investigated.

In some conditions, fluid buildup may be detected before it causes serious damage. Overall, continuous weight monitoring, without the need for actual transfer of the body, greatly reduces injuries.

According to SonderCare,

Advances in bed technology include vital signs monitoring and alerts to prevent pressure ulcers, increasing safety and comfort for patients. Future innovations will incorporate smart fabrics and touch-sensitive sensors that offer real-time health updates directly into electronic medical records.

But wait, there is more…

Another entire area in which very large people can be particularly vulnerable is medication dosage. We are accustomed to the idea of child-size doses, to ensure that the young and vulnerable don’t get too much. But we think less often about the need for accurate measurement in the ratio of medication to body weight, in the case of an extremely large adult.

Both insufficient dosage and overdosage would be problematic. GoodRx.com says,

Some medication dosages are weight-based because your body weight or body composition could affect their absorption, distribution, metabolism, or elimination. These four factors predict how a medication will behave in your body. Drug toxicity can also play a role.

Changing any one of these factors can potentially make a medication more or less active in your body. In turn, this can lead to unwanted side effects or a less effective treatment.

Another paper points out that “the weight effect may be minimal or dosage can be affected only when weight is combined with other factors. Findings of sporadic studies in recent years indicated that fixed dosing was more advantageous than weight-based dosing in some cases…” It stresses that the medical facility needs to establish good processes for both weighing and documentation, and to ensure “sufficient and convenient availability of appropriate and properly functioning equipment for patient weighing and medication delivery.”

Insulin, antibiotics, and anesthetics are some of the drug types that need very careful consideration when prescribed. In the overall cost of obesity, this factor is not very large. Although considering it over and over again in each case certainly takes time, which adds up. But just one case that goes to court because a patient was under-treated or died from an overdose can become very expensive.

Any reader of this piece who treats lightly the matter of dosage calculation might take a look at this website, “How To Calculate Drug Dosage By Weight | Essential Guide.” This excerpt is just a tiny sample:

\[
\text{Required Volume} = \frac{\text{Total Dose}}{\text{Available Concentration}} = \frac{700 \text{ mg}}{250 \text{ mg/mL}} = 2.8 \text{ mL}
\]

Got that? This is why medical school is so expensive, and why physicians are so well-compensated. The matters discussed here are relevant not only to the status of obese children as they exist now. The whole area of concern involves viewing children not just as young people per se, but as precursors of the adults they will grow into.

We strive to avoid these very costly problems, both for the sake of each individual child and for the sake of the economy, as they will grow up to impact with their ever-increasing number of expensive obesity-related issues.

Bariatric Hardware By the Numbers

In this series concerning the costs of obesity, today’s post is about equipment. We mention some specifics of why the issue is an ongoing and ever-growing problem for patients, family members, and/or caregivers, medical professionals, other hospital personnel, insurers, and basically the American public at large.

“Bariatric” is a term that refers not only to weight reduction surgery but to the entire field of obesity treatment. Let us confront the issue of equipment — first, by looking at some available devices. Several sources were consulted for bits and pieces of information; a typical website of this genre describes items designed for patients in their everyday lives at home and out in public.

Crutches can be found for people who weigh up to 650 pounds and maybe even heavier. There are canes guaranteed to support 500 pounds. Specialized companies make extra-wide, super-strong walkers. A combination walker and seat called a rollator will support up to 500 pounds and run you $800 or more.

An extra-wide wheelchair that supports up to 850 pounds can be had for just under $1,000, while a less sturdy model might go for half that price. And who would have guessed that a “transport chair” is a whole different category of item?

Other locales

For the home, a furniture company has designed a super-strong lounge chair that can be had for around $2,500, and a scooter available for approximately $3,750. A special bed for home use can serve a person of up to 450 pounds (or even heavier), but the basic horizontal structure itself is only the beginning. The side rails, for instance, may represent a separate, additional expense.

A home bed may cost around $3,000, but quite possibly might add up to more. In a hospital, a high-tech, specialized bariatric care bed could run for 10 times as much. A mattress particularly designed for very obese individuals is composed of different materials from the standard hospital mattress, and may cost as much as $4,000.

In either case, the patient will probably need a trapeze (around $1,000) to lift himself or herself off the bed’s surface and change the body position. For patients who need help when in physical therapy recapturing their ability to walk, there are ceiling lifts.

Similar devices are able to lift a very large person from the floor onto an exam table or bed. Although modern hospitals are designed from scratch with such contingencies in mind, the structure of a typical home might need some expensive refurbishment to handle a suspended load of this kind.

Different strokes for different folks

For more intimate needs in the individual’s bedroom and/or bathroom, there are transfer benches to help get a person on the toilet; bedside commodes (starting at around $200), shower chairs, raised toilet seats, toilet safety rails, and other beefed-up versions of standard items, and they all cost more if a lot of poundage is involved.

Equipment that will probably be found only inside a medical institution includes an extra-sturdy exam table that sells for around $2,000. For the use of the bariatric surgeon, special stapling equipment is available in the $4,000 – $5,000 range. But this begins to impinge on a whole different, related area.

Let’s take a moment to scope out an article about patient safety, with a long and explicatory title: “How Safety Is Compromised When Hospital Equipment Is a Poor Fit for Patients Who Are Obese.”

This assessment is five years old, but not much has changed since then:

Event reports […] indicate that some healthcare facilities do not have the necessary equipment to monitor and care for some individuals in this patient population, leading to embarrassment for patients, delays in care, and injuries to patients.

The most frequent problem situations involve imaging equipment, “especially MRI and CT scanners,” or at least events in the imaging department. Stretchers and wheelchairs are statistically implicated to a startling degree. Almost 75% of patient safety mishaps result in what is euphemistically called “a delay in care,” with most of the delays consisting not only of pausing to assess the damage, but in treating the resulting damage. Nobody wants this.

A huge field of knowledge is involved here, which mainly concerns adult patients rather than children. But this is the point we make again and again: The odds of an obese child growing into an obese adult are daunting. No parent wants to peer into the future and see this kind of picture. And looking at a bit of specialized bariatric equipment, and the associated prices, hopefully will cause some degree of a “scared straight” effect.
