Diabetic diets – clinically appropriate in aged care or not?

When balancing the clinical needs, requests and preferences of each resident in-conjunction with their right to choose, a number of factors need to be taken into consideration.  We all recognise that theory and practice can change over time so when I asked Liz Beaglehole (Registered Dietitian) her professional view on this topic is, she offered the following:

 

The recommendation for older adults with diabetes in aged care facilities with stable diabetes is to provide an unrestrictive diet as much as possible. The notion of a ‘diabetic diet’ is outdated due to the increased risk of hypos and unwanted weight loss.

 

This is very individual however, a frail 80 year old woman with diabetes will likely have no diet restrictions however an obese 70 year old who may be otherwise stable would benefit from a more restrictive diet.  Advice from a dietitian for individuals is recommended.

 

Overall, guidance from the resident about their wants is probably what determines the diet provided. This may be in accordance with recommendations or not.

 

Generally, the medications should be fitted to the usual eating pattern of the resident.  In aged care facilities there are regular meals and generally balanced carbohydrates over the main meals (assuming good food intake) so usually this is fine.  If someone has a reduced food intake, and is on insulin then a unrestrictive diet would be best.

 

For my menu planning I tend not to plan any special diabetic options on the cycle menus.  I may include a low fat / low sugar dessert option if sites request, but generally my philosophy for aged care is not to restrict foods!

 

Liz is involved with a PEN (practiced based evidence in nutrition) review of the question ‘Do institutionalized, older adults (65 years of age or older) who closely follow a diet prescription have better control of their chronic disease (e.g. diabetes) than those who do not?‘ This is due by the end of March so further practice updates from this review may be available then.  Liz noted that generally the evidence suggests there are no benefits with a prescriptive diet vs a more liberal one.

Dysphagia Diets – Are we all understanding each other?

Dysphagia diets and a lack of understanding of how to implement them consistently, is increasing risk to residents in aged residential care services.

Texture modified diets are commonly used in aged care facilities to manage the risk of aspiration pneumonia and choking with eating and drinking.  Residents with dysphagia may be placed on a texture modified diet following assessment with a speech and language therapist.  However there are often a range of terms used for texture modified diets, and differing opinions on exactly how the diets should be prepared.

 

Confusion with terms, and the types of foods and fluids offered leads to increased risk of harm for the resident.  This is particularly obvious when transferring from one facility to another.  Information on texture modified diets is passed to the new facility who may use different terms.  For example a site may report ‘this resident requires a soft diet’ and the interpretation of this diet at the new facility is to puree all food.

 

The International Dysphagia Diet Standardisation Initiative (IDDSI) is a framework to standardise terminology and offer simple testing methods to check that the preparation of the diets are correct. Dietitians New Zealand and Speech Language Therapists of New Zealand have endorsed in principle the IDDSI framework.

The goal is to reduce the risk of harm for our patients and residents due to miscommunication and poorly prepared texture modified diets.  It is important to note that the framework relates to dysphagia diets only.  Residents may be on a modified diet due to other factors not related to dysphagia.  For example a resident with no teeth may need softer foods but can actually manage sandwiches.

The good news is that for many sites, there is very little change needed as they are already using the correct terms.  The diagram above shows the new terminology and the minimal change in wording;
  • ‘Smooth puree’ becomes pureed (which is also extremely thick fluids)
  • ‘Minced and moist’ remains unchanged
  • ‘Soft diet’ becomes ‘soft & bite sized’
  • Moderately thick and mildly thick remain unchanged for thickened fluids
The IDDSI framework assigns standard colours and numbers to assist with easily identifying texture modified foods and fluids.  Some manufactures of texture modified foods and fluids are looking at ways to incorporate the terms, colours and numbers onto their food packaging.

 

Food and Fluid Preparation and Testing

The IDDSI framework offers simple tests to check that the thickness of the fluids or the size of the particles for modified foods are correct.  The tests use forks, spoons, fingers or syringes – equipment that is readily available at sites.

With training and education on how to do these tests, kitchen staff and managers will be able to easily check their texture modified diets and thickened fluids are prepared correctly.

 

IDDSI App and Website

The IDDSI framework have developed many resources and videos to assist with the standardisation process.

Download the app https://play.google.com/store/apps/details?id=com.appdataroom.iddsi&hl=en

or go to www.IDDSI.org

or ask your dietitian and speech language therapist for more information.

 

Where to From Here?

Here are some small steps to help implement the IDDSI framework at your site:

  1. Stop using any terms that are not on the framework. The term ‘mouli’ is not recognised and should not be used to describe a texture modified diet.
  2. Download the app or look at the IDDSI website to familiarise yourself with the framework.
  3. Try testing one of the textures you currently prepare. Does the ‘puree diet’ your site produce pass the spoon tilt test?  Does the size of the minced food for ‘minced & moist diets’ fit between the prongs of a fork?  Is the size of meat offered for residents on the ‘soft & bite size diet’ the size of your thumb nail?
  4. Ask your dietitian or SLT for further training on the correct testing and preparation of dysphagia diets.

Unintentional weight loss

A very common adverse clinical outcome for residents is unintentional weight loss. It can contribute to a decline in general health, energy, about to heal in relation to skin / wound care and increase the risk of accidents.

Ensuring adequate nutritional intake relevant to the health status for each resident is ultimately the responsibility of Registered Nurses. There has been the perception in some instances that it’s normal to lose weight as people age. While there is an increased tendency to lose weight, it should not be considered normal.

If unintentional weight loss is detected, ensure thorough multi-disciplinary clinical assessment and development of specific short term care plan to define strategies to meet the specified care plan goal. Offering more frequent high energy (high calorie) and high protein snacks and drinks between main meals and instigating the recording of all food and fluid intake should be part of this plan (unless contraindicated). The dietitian can best help guide you through the best nutritional support for each individual resident and their circumstances at the time.

Unintentional weight loss or the undesirable decline in total body weight over a specified period of time is common however should not be ignored as ‘part of ageing’.  Sarcopenia (muscle loss in the elderly) is also common however not inevitable and should be addressed through a targeted exercise and balance programme. Light body weight in the elderly have been shown to have a detrimental effect on the resident ability to function and on their general quality of life.

Unintentional weight loss of 3 -5 percent (or greater) in 30 days (or 10 percent in 180 days) must be monitored more closely and a short term care plan must be developed to promote weight loss cessation and implementation of weight management practices. RN’s must ensure they review regular weight monitoring records to identify progressive changes and respond to adverse patterns.

Residents that have been determined to be in later stages of palliative care or receiving terminal cares should be excluded from the need for close monitoring and related care planning related to trying to reverse unintentional weight loss.  This is at the discretion of the Registered Nurse in consultation with the Doctor and next-of-kin / advocate / whanau.  Discussions will also be had with the resident and the Medical Practitioner regarding the extent or type of tests, investigations and interventions that are desirable.  These must be clearly documented in the Care plan evaluation and interventions recorded in the long term care plan and Doctors consultation notes.

Ensure the specific instructions (interventions) are recorded in the care plan for staff to implement on a consistent basis.  Ensure these are reviewed at each weight monitoring event (time-frame specified in care plan) and adjust interventions according to weight monitoring outcomes.

If after two weeks of weekly monitoring the weight has not stabilized or started to increase, consult a Dietitian to review the resident and provide recommendations.  Ensure any recommendations are followed as directed.

Treat any underlying cause and continue monitoring of weight until it has reached optimum levels in accordance with care plan goals.  Return to monthly monitoring of weight at this stage.  Those on special diets must be monitored more closely than those residents that are independent with eating and drinking or those that have no identified difficulties which may lead to increased potential for unintentional weight loss.

Case Study:

An 84 year old female resident (Mrs A) with a diagnosis of chronic heart failure and early dementia was noted to be experiencing progressive weight loss. Staff indicated she was able to physically feed herself but often refused to eat, pushing the meal tray away from her.  She was able to express her needs to the extent of saying she didn’t want her meal. Staff recorded this in the progress notes however no investigation was done to identify the cause of her refusal to eat. Her weight had reduced at that point to 38kg having had an admission weight of 48kg only six months previously. Staff noted Mrs A was often sleepy during the day and expressed their belief her dementia was advancing. A new Clinical Nurse Lead (CNL) sat down and talked with Mrs A to discover that her mouth wasn’t sore and her dentures were well fitting. There appeared to be no difficulty with her ability to eat or swallow.  The CNL consulted with the dietitian to support the assessment process. It was decided that a staff member would sit with Mrs A and gently talk with her as the staff member offered small spoonfuls of food.  Mrs A obliged with eating with no resistance or protest and seemed to enjoy her meal. Progressively day after day her intake increased and she seemed to be sleeping less. She had more energy and within a period of one week had shown an 800 gram weight gain.  Staff continued with supporting Mrs A with assisting her with her meal and within 6 weeks her weight had increased from 38kg to 41kg.  At that time she was no longer sleeping most of the day and had resumed feeding herself. Short term care plans were instigated at the start of this process and more detailed long term care planning and regular assessment was also documented. Family input had been sought to gain a greater understanding of Mrs A’s previous eating patterns and she was able to talk about the foods she enjoyed having with her family.  Asking questions about a context such as family meals assisted the staff in gaining more information than if they’d simply asked Mrs A what her favourite foods were.  Giving a direct answer to a specific question wasn’t easy for Mrs A however she was able to talk about family meal times which proved a valuable source of information for nursing staff in supporting her. At the end of an 8 week period Mrs A had more energy, was interacting more with others, was sleeping less during the day,appeared happier and was enjoying her meals. She was no longer refusing to eat.  It stands to reason that when a person is lacking nutrients, they may actually lose the energy needed to feed themselves.  Getting the basics right is a good place to start.
