Resident Violence | The Broset Violence Checklist

Introduction to the Broset Violence Checklist

The Broset Violence Checklist is a simple, six item list that was developed to predict violent behavior in psychiatric patients before it escalated into a dangerous episode of resident violence.  Use of this checklist was found to be useful in identifying patients who were beginning to decompensate and allowing staff to implement appropriate measures to prevent violent attacks. It’s use in nursing homes has not been routinely reported but might provide a useful tool to help prevent resident-on-resident or resident-on-staff violence.

Background on Nursing Home Resident Violence

Increasing episodes of violent behavior by nursing home residents against staff or other residents have been reported.  Consequently, working as a nursing assistant has been found to be more dangerous than working as a coal miner.  The internet has an abundance of plaintiff attorney sites highlighting the problem and offering their legal remedies for the resident violence situation. Reasons for the increase in nursing home resident violence include:

  • more robust reporting of incidents due to heightened awareness and federal regulations,
  • an influx of sicker, more behaviorally disturbed dementia residents into nursing home care,
  • the admission of greater numbers of severely ill psychiatric patients into the long term care setting due to closure of psychiatric hospitals and clinics

Decreasing funding for nursing home care, increasing care expectations from regulators and the public, and the totally delusional belief that resident needs are better met by expanding the number of staff involved in paperwork and decreasing the number of actual care-givers contribute to the problem as well.

Predicting Resident Violence with the Broset Violence Checklist

The Broset Violence Checklist is used to predict the likelihood of violent behavior within the next twenty-four hours. The six-item resident violence behavioral checklist includes:

  1. confusion
  2. irritability
  3. boisterousness
  4. physical threats
  5. verbal threats
  6. attacks on objects

Scoring the Broset Violence Checklist

Each item in the checklist is either present (1) or absent (0) in the scoring system and the scoring is done against the patient’s normal baseline behavior.  Scoring is: 0  -                       Small risk of violence 1-2                       Moderate risk of violence 3 or greater        Very high risk of violence For high risk residents preventive measures are required and plans for handling or preventing an attack should be activated immediately.

Potential Use of the Broset Violence Checklist in a Nursing Facility to Prevent Resident Violence

Prior to, or upon admission to a nursing facility, an assessment of the resident’s prior behavior should be obtained.  A history of violence should lead to development of plans to identify and interventions to prevent resident violence.  Residents with a history of violence need frequent monitoring to establish knowledge of their baseline behavior and clues to impending aggressive episodes.  Use of the Broset Violence Checklist at regular intervals might provide an earlier, objective warning to staff that a resident is starting to escalate.  Behavioral or medical interventions should then be implemented such as removing the resident form common resident areas, using two persons for personal care, and possibly, initiating or increasing psychotropic medication to calm the resident.

Conclusion

The Broset Violence Checklist might be a useful tool in preventing resident violence in nursing facilities.  By anticipating the likelihood of violence within the next twenty-four hour period,  interventions could be implemented before, rather than after, violence occurs.  Though it has not been formally studied in the long term care setting its utility in predicting violence in psychiatric institution patients indicates its potential utility in nursing home residents, many of whom have severe psychiatric illness.

Osteoporosis Treatment – The Bisphosphonates

Overview of Bisphosphonates in Osteoporosis Treatment

The bisphosphonates (Fosamax, Actonel, Boniva, Reclast, Zometa) are frequently prescribed for treatment of osteoporosis.  They work by inhibiting osteoclasts. Osteoclasts are bone cells that breakdown old bone and allow for ongoing remodeling of bone.  This leads to bones that are denser on X-ray and will give better bone densitometry scores.  Bone density on X-ray has been used as a surrogate for bone strength and fracture risk reduction in many reviews on the efficacy of these drugs.

Efficacy of Bisphosphonates in Preventing Osteoporosis-Related Fractures

Bisphosphonates have a modest effect on secondary prevention of spine and hip fractures in persons with diagnosed osteoporosis (t score < -2.5) or a prior osteoporosis-related fracture.  They have no proven benefit in preventing fractures in people without osteoporosis (primary prevention) although many women, diagnosed with osteopenia (t-scores between -1 and -2.5 receive these drugs for primary prevention.  According to a study published in the Journal of the American Medical Association (JAMA) a woman with osteoporosis taking alendronate (Fosamax) daily for four years would reduce her risk of hip fracture from 2.2% to 1 %,  a 1.2% absolute risk reduction.  In other words,  roughly 80 women (number needed treat  100/1.2 = 83) would need to take Fosamax for four years to prevent one additional hip fracture. The numbers for other bisphosphonates are equally unimpressive.

Side Effects of Bisphosphonates

Bisphosphonate use is associated with a number of adverse effects including esophagitis (inflamation of the esophagus), musculoskeletal pain/cramps, an abnormal heart rhythm (atrial fibrillation), osteonecrosis of the jaw, and atypical fractures of the femur after prolonged (>5 years) use.

Contra-indications to Bisphosphonate Use

Bisphosponates should not be used by patients with a known prior allergic reaction to them, severe kidney disease (Chronic Kidney Disease stages 4, 5), low calcium levels, vitamin D deficiency, or persons who cannot sit up for 30 minutes after taking the medication.  Additionally, persons with impaired swallowing (dysphagia), esophageal disorders, or severe GERD (gastroesophageal reflux disease) should not take these medications.

Bisphosphonates in Long Term Care Patients

Long term care residents with osteoporosis present their own unique challenges regarding treatment.  First, data is lacking for prevention or treatment of osteoporosis in people over 80 years of age ( a large portion of the nursing home population).  Second, most of the studies involved osteoporotic women with prior fractures so there is little data on primary prevention or treatment in men.

Many residents are immobile and are unlikely to benefit from any medical intervention except fall-prevention. Dementia, one of the primary reasons for nursing home admission, makes following instructions for safe/effective administration of oral bisphosphonates problematic. Swallowing problems (dysphagia) are very common in nursing home residents and make oral bisphosphonate use difficult, if not impossible.   Many nursing home residents have poor renal function and are not candidates for these medications.

Finally, many older persons take multiple medications for their chronic conditions. Medication passes in the nursing facility become very difficult, and prone to errors, when the complexity of administering drugs that require specific instructions like sitting up for 30 minutes and taking only on an empty stomach with a glass of water (many residents can’t drink an entire glass of water) are required.  incorrectly administered medications may expose the resident to substantial risks for side effects (like esophagitis) without offering much benefit.

Conclusions

Although bisphosphonates are widely used for prevention and treatment of osteoporosis their risks versus benefit for many nursing home residents is unacceptable.  In the subset of residents who are younger, more active and cognitively intact, they may offer modest benefit for those with established osteoporsis.

It is important that you do not reduce, change, or discontinue any medication or treatment without first consulting your physician.  These recommendations are offered as generally informational and are not to be used as specifically applicable to any patient’s medical problems.

Osteoporosis Treatment – The Basics

Osteoporosis Treatment Overview

Osteoporosis treatment may be divided into basic, low risk/cost interventions, and pharmacologic, higher risk/cost, approaches.  Basic treatment should be considered for both prevention and treatment of all persons at risk for or with a diagnosis of osteoporosis. This level of intervention includes exercise, smoking cessation, limiting alcohol intake, maintaining adequate vitamin D and calcium levels, and decreasing or avoiding medications that may cause or worsen OP. Although inexpensive and safe, this approach is frequently overlooked or eschewed for the more expensive/higher risk, pharmacologic option, just as it is for many other chronic illnesses like diabetes, hypertension, and arthritis.

All persons at risk for, or diagnosed with, osteoporosis should be educated on how to prevent falling. Falls are the major cause of osteoporosis-related fractures.

Osteoporosis – Basic Treatment

According to the National Osteoporosis Foundation, Universal Recommendations for All Patients include: adequate calcium and vitamin D intake, daily weight bearing and strengthening/stretching exercises, fall prevention, and avoidance of smoking and excessive (greater than 3 drinks per day ) alcohol consumption.

Calcium intake should be at least 1200 mg per day but intake above 1500 mg offers no additional benefit and may increase the risk of kidney stones or cardiovascular disease.  Vitamin D intake of 800 to 1000 IU daily is recommended to maintain healthy bone metabolism.  Dairy products provide the most common source of dietary calcium intake and sun exposure is the primary way most people get Vitamin D.  However, many adults do not ingest enough dairy products to maintain adequate calcium intake and concerns about skin cancers secondary to sun exposure have decreased this mechanism of obtaining Vitamin D such that supplementation for both is often necessary.

Exercising to prevent osteoporosis involves both weight bearing and resistance exercises.  Weight bearing exercises involve activities like walking, hiking, tennis, golf (walking), housework, gardening, yoga, and other activities where one is bearing weight on the spine and extremities.  Resistance training involves lifting weights or using resistance bands (stretchy rubber bands) to build muscle and bone strength.  Obtaining advice from your physician or an exercise trainer is recommended prior to initiating an exercise program if you are not a regular exerciser in order to avoid injury or adverse health events.

Limiting alcohol consumption to no more than one drink per day for women and two for men is recommended for general health reasons and will help decrease the risk for OP.  Smoking is to be avoided for a host of  health reasons including its effects on bone health.

Avoiding Medications That May Cause or Worsen Osteoporosis

A number of medications may accelerate bone loss. Commonly prescribed medications that may lead to bone loss include: phenytoin (anti-seizure medication), glucocorticoids (used to treat many inflammatory diseases), excessive doses of thyroid medication,  proton pump inhibitors (like Prilosec and Protonix used to treat esophagitis or ulcers), SSRI’s (a class of anti-depressant medication), and anti-diabetic drugs like Actose and Avandia.  These medications alter bone metabolism in various ways to accelerate loss.  Persons with osteoporosis should discuss these medications with their primary care physician to see if they can be stopped or if a less bone-damaging alternative may be prescribed.  Do not stop these medications without consultation with the prescribing physician.

In the nursing home setting inactivity and limited access to sunshine increase the chances of developing or accelerating osteoporosis.  This can be combatted, to some degree, by daily physical exercise activities, walk-to-dine programs, calcium and vitamin D supplementation, and regular review of patient medication records.  Although smoking by nursing facility residents is fairly common, cessation usually occurs as residents become too frail to go outside to smoke. Excessive alcohol intake in usually not a problem.

 

 


Osteoporosis Treatment – Pharmacologic Treatment

Introduction to Pharmacologic Treatment of Osteoporosis in the Long Term Care Setting

The previous blog covered the simple, inexpensive ways to prevent and treat osteoporosis (OP) .  This post will review commonly used pharmacologic interventions.  Since this site reviews topics from the viewpoint of treating long term care residents, some treatments that might be appropriate in more vigorous, healthy persons, may not be covered.

Limitations of Studies on Osteoporosis Screening and Treatment

In reviewing the pharmacologic interventions employed to treat osteoporosis it is necessary first to discuss the limits of our understanding of osteoporosis screening and treatment in the nursing home population.  Most of the data on osteoporotic-fracture prevention (the objective of treatment) comes from studies on white women less than 80 years old with established osteoporosis. There is minimal data on the effects of treatment on men or persons over age 85, the appropriate age to discontinue screening and treatment for OP, and the potential harms of screening and treatment in nursing home residents.

Medications Commonly Used to Treat Osteoporosis

Before embarking on pharmacologic treatment of OP it is essential to make sure that patients have adequate calcium and vitamin D levels.  Although some of the medications used to treat osteoporosis will provide minimal, or no, significant benefit under optimal conditions, they may cause actual harm in calcium or vitamin D deficient persons.

Drugs commonly used to treat osteoporosis include: the bisphosphonates (Fosamax, Actonel, Boniva, Zometa, and Reclast), estrogen in post-menopausal females, testosterone in post-andropausal males, SERMs (selective estrogen receptor modulators – Evista or Tamoxifen), calcitonin, parathyroid hormone teriparatide (Forteo), and  the monoclonal antibody (Prolia). In nursing home residents the most commonly used medications are bisphosphonates and calcitonin.

Estrogen replacement, beginning shortly after menopause, is effective in preventing fractures.  Though used fairly extensively in the past it has fallen into disfavor due to its adverse effects on cardiovascular health and its potential to increase the risk of uterine and breast cancers.  Testosterone, in elderly men with testosterone deficiency, may help overall well-being but the effects on bone are not well-studied. SERMs are still used occasionally but increase the risk of  blood clots (thromboembolic disease), leg cramps, edema, and flu-like symptoms.

Calcitonin is an old drug which is an inhibitor of bone resorption.  It is used as a nasal spray and is only indicated for prevention and treatment of vertebral fractures.  It may have pain-relieving effects for vertebral fractures in some persons.

Forteo and Prolia are both used rarely in LTC residents.  They are very expensive and would not be appropriate for most nursing facility residents. In younger, more active residents, they may be appropriate if simpler, more commonly used treatments, have failed.

Bisphosphonates to Treat Osteoporosis

Bisphosphonates alter bone metabolism by inhibiting osteoclast activity.  Osteoclasts are bone cells that break down old bone and allow for ongoing remodeling of bone.  It is believed that inhibiting osteoclastic breakdown of old bone makes bone stronger.  However, this may not be the case in long term use of these drugs as recent studies have shown atypical femoral shaft fractures to be associated with prolonged (>5 years) use.

Despite all the hype made about these drugs on television direct-to-consumer ads and in medical conferences by “experts” sponsored by drug manufacturers, they are simply, in my opinion, underwhelming.  It is a testament to the effectiveness of marketing that these drugs generate billions of dollars in sales for their makers.

The next section of this blog will review bisphosphonates in more detail and will discuss their effect on primary and secondary fracture prevention, side effects, and practical considerations for using them in the nursing home population.

Statistics and Science

Recent Study shows 70/30 split in favor of Heads, Make Money Today!

I recently performed a study to determine whether or not flipping a coin was truly a 50/50 proposition.  The results were astonishing.  My study found that when flipped a penny would come up Heads as much as 70% of the time.

Using my revolutionary new strategy you can make hundreds of dollars a day in Vegas by simply…

Clearly most of us would recognize this type of hype as a scam.  However, it isn’t technically a lie.  I did flip a penny and I did get a 70/30 split in favor of Heads over Tails.  What does this mean?

Statistics and Science

At the heart of developing new medications and new treatments for curing ailments is science.  Science in the form of studies conducted to determine effectiveness and possible side effects.  The results of studies are presented in statistical form.

Statistics are a nebulous thing to define.  Let’s take flipping a coin as an example.  We want to know what the probability is of getting heads when we flip a coin; it should be approximately 50/50 but I got a 70/30 split.  Since we come to this article believing that a penny should result in an approximate 50/50 split we immediately begin asking appropriate questions about the validity of my study:

  • Q: How many times did I flip the coin for each set?  A: 10
  • Q: What coin was I flipping?  A: It was a 2010 penny with Lincoln’s profile as heads and the shield instead of the Lincoln memorial for tails
  • Q: Was the coin clean? A: No
  • Q: Was I flipping the coin inside or outside in the wind? A: Inside
  • Q: Did I flip the coin the same height with the same rotation speed each time or were these random? A: Random, I’m only human and didn’t use a machine to flip the coin
  • Q: Did I count the result if I dropped the coin and it bounced off the floor? A: No, I only counted flips that I caught but some flips got caught in the lines in my palm and therefore didn’t lie flat.  I then had to decide if they counted and if they counted were they heads or tails.

This is just a small sample of the number of valid questions I might ask of anyone presenting results in our penny flipping example.  But, we (myself included) often forget to ask the same questions when we don’t already know the answer such as in the case of the effectiveness of a new medication.

What constitutes a valid study?

Test Set: % Heads % Tails
#1 40 60
#2 70 30
#3 50 50
#4 60 40

First off, for a study’s results to have any meaning at all the study must include a statistically significant number of trials.  In our penny flipping example I did 4 sets of 10 flips.  Our 70/30 split clearly demonstrates that no single set of 10 flips is an adequate sample size for determining whether or not the split is actually 50/50.

And frankly flipping a penny is about as simple a statistical test as you can perform because the variables to control are few:

  • do the test inside without wind
  • do the test multiple times with multiple pennies
  • do the test on multiple days with multiple people
  • do the test with other coins – quarters, nickels, and specially designed (loaded) coins – in order to see if the flippers are influencing the results

Even a simple penny flipping test can require the consideration and control of a lot of factors.  And yet we have studies on people (much, much more complicated systems to study than a coin) which include only a dozen or a couple of dozen participants.  What can a study on people with 10-20 participants possibly prove when you can’t even prove a coin has a 50% chance of coming up Heads with only 10-20 trials?

Conclusion

There is a saying out there often attributed to Mark Twain that goes “there are lies, damn lies, and statistics”.  Unfortunately, most people presenting you with statistical “evidence” have a belief they wish to “prove” as opposed to letting the facts and statistics lead them to a conclusion.  And most journalists don’t know enough about statistics or science to know good science from garbage.  They do, however, know what kind of headlines sell well.

When a news outlet presents the results of a breakthrough medical study find out how many perticipants were involved, what were the controls on the study and has anyone been able to duplicate the results.  If there weren’t at least 1000s of participants then its an anecdote not scientific proof of anything.  And every study in any science is worthless until is can be duplicated.

Some researchers are frauds- like Andrew Wakefield (vaccines and austism).  Some researchers make mistakes – like the guys who announced cold fusion.  (As I remember it no one accused the cold fusion guys of lying so much as not properly documenting their work making it impossible to duplicate.  And probably having made a mistake in the accounting of how much energy they were putting into their cold fusion system leading to an erroneous conclusion.  Research in the area is still on-going under different names.)
