1 | INTRODUCTION
Texture-modified diets (TMDs) are a necessity for many res-
idential aged care facility (RACF) residents, whether due to
swallowing difficulties (dysphagia), poor dentition, sensory,
physical and/or cognitive impairments.
1
Internationally,
prevalence of TMD use in RACFs has been reported as being
between 15% and 30%.
2
Residents on TMDs have been shown
to have lower energy intake and increased risk of malnutrition
and are more likely to require feeding assistance compared to
residents on regular diets.
3-5
Increasing mealtime assistance,
improving the appearance, taste appeal fortification of TMDs
have all been shown to result in improvements to intake and
weight for older adults in RACFs.
6,7
Limited investigation
of TMD practice in New Zealand aged care settings pro-
vides little guidance to food service and health profession-
als considering service improvement initiatives. Typically,
dietitians and speech-language therapists provide resident-
specific nutritional and swallowing support on request and
offer sporadic training. Although not mandated, many of the
larger RACFs employ a dietitian to advise on their seasonal
menus. The aim of this mixed methods exploratory study was
to characterise the prevalence and characteristics of residents
on TMDs in RACFs, exploring food consumed, nutritional
and dysphagia diet compliance, menu quality, dining room
experience and feeding assistance.

Objectives: Over 35 000 people live in residential aged care facilities (RACFs) in
New Zealand. Texture-modified diets (TMDs) are commonplace. They are associ-
ated with malnutrition. The aim of this study was to characterise TMD prevalence
and practice in RACFs.
Methods: Data from 35 460 residents were extracted from the interRAI™ database.
Mealtime observations (including 459 residents), meal audits (IDDSI, 2018) and
menu audits (Dietitians New Zealand Menu Audit Tool for RACFs 2013) were com-
pleted at 10 RACFs.
Results: One-third of residents were on TMDs. Half the residents ate full meals.
Feeding assistance was more common in residents on TMDs compared to those on
regular diets (P < 0.001). The majority of pureed meals met IDDSI standards; none
of soft and bite-sized meals complied. TMD carbohydrate and protein servings did
not comply with standards.
Conclusions: Texture-modified diets reflect 1/3 of meals produced in RACFs. This
study provides insight into TMD use in RACFs and highlights service gaps and train-
ing opportunities.
