Thickened Liquid Challenge Strikes Back - #ThickenedLiquidChallenge



by: Eric Widera (@ewidera)

This week's JAMA IM includes a case of a woman in her 90s with advanced dementia who was started on honey-thickened liquids for aspiration prevention.   She subsequently “refused nearly all food and thickened liquids, turning her head when nurses attempted one-on-one feeding” and was transitioned to inpatient hospice care.   What happened next?  Her diet was changed to regular liquids and she was allowed to eat her favorite foods.  Two months late her weight improved with no clinically apparent aspirations.

This is the story of thickened liquids.   As the authors of the article, Drs Wang,  Charlton, and Kohlwes, explain: “thickened liquids have become a part of routine care—some might even argue the standard of care. This has created the perception that thickened liquids are beneficial and safe for patients with dementia.”  Unfortunately, the evidence base to back up its efficacy in dementia is poor and as in this case, places patients at significant risk of adverse effects.  

We at GeriPal are personally proud that the authors described one of the most important interventions that providers can do when placed in situations like these where the “standard of care” is questionable at best: they tried it themselves.  The authors describe undertaking the “Thickened Liquid Challenge” by filming each other as they as they endured 12 hours of a thickened-liquid diet.   What was their conclusion after doing so?   Its summarized perfectly in their last sentence:
"The routine use of thickened liquids to prevent pneumonia in patients with dementia should be avoided, and diet should involve a comprehensive approach rather than a reflexive diet modification."

The Dangers of Fleet Enemas

The dangers of oral sodium phosphate preparations are fairly well known in the medical community. In 2006 the FDA issued it’s first warning that patients taking oral sodium phosphate preparations are at risk for potential for acute kidney injury. Two years later, over-the-counter preparations of these drugs were voluntarily withdrawn by the manufacturers.  Those agents still available by prescription were given black box warnings mainly due to acute phosphate nephropathy that can result in renal failure, especially in older adults. Despite all this talk of oral preparations, little was mentioned about a sodium phosphate preparation that is still available over-the-counter – the Fleet enema.

Why Oral Sodium Phosphate Preparations Are Dangerous 

Before we go into the risks of Fleet enemas, lets spend just a couple sentences on why oral sodium phosphate preparations carry significant risks. First, oral sodium phosphate preparations can cause significant fluid shifts within the colon …

Length of Stay in Nursing Homes at the End of Life

One out of every four of us will die while residing in a nursing home. For most of us, that stay in a nursing home will be brief, although this may depend upon social and demographic variables like our gender, net worth, and marital status. These are the conclusions of an important new study published in JAGS by Kelly and colleagues (many of whom are geripal contributors, including Alex Smith and Ken Covinsky).

The study authors used data from the Health and Retirement Study (HRS) to describe the lengths of stay of older adults who resided in nursing homes at the end of life. What they found was that out of the 8,433 study participants who died between 1992 and 2006, 27.3% of resided in a nursing home prior to their death. Most of these patients (70%) actually died in the nursing home without being transferred to another setting like a hospital.

 The length of stay data were striking:

the median length of stay in a nursing home before death was 5 months the average length of stay was l…

Palliative Care in Nursing Homes: Discussion of a Multinational Trial with Lieve Van den Block

Nursing homes are a tough place to do palliative care.  There is extremely high staff turnover, physicians are often not present except for the occasional monthly visit, many residents die with untreated symptoms usually after multiple hospitalizations and burdensome life-prolonging treatments, and specialty palliative care - well that is nowhere to be found in most nursing homes outside of hospice.  So what can we do to improve the palliative care outlook in nursing homes?

On todays podcast we talk with Lieve Van den Block about her recent palliative care intervention that was published in JAMA IM this week.  Lieve led a multicomponent intervention to integrate basic nonspecialist palliative care in in 78 nursing homes located in 7 different European countries.  Just take a moment to grasp the size of this study - 7 counties, 78 nursing homes.  I struggle with just trying to improve palliative care in one site!

We discuss with Lieve the results of the study, her take on why they got…
