The club is financing the University of Leicester's Parental Expression of The Acuity of iLLness (PETALL) study, which is investigating how parents and carers express their concerns about children's health.
Researchers plan to produce a language guide to help parents convey what they mean so that doctors and nurses can get the most out of the interaction.
Project lead Damian Roland, associate professor of paediatric emergency care at the university, claimed there had been examples of children suffering life-changing illnesses, or even dying, because doctors and nurses had been slow to pick up on critical information.
Roland suggested that misunderstandings could result from how concerned or unconcerned parents appeared.
A current system of scoring - paediatric early warning scores (pews) may work better if they measured parental concern, suggested the professor.
Roland said a new system could include options to describe children's state of health, such as: "This is the most concerned I've ever been about my child", "I've seen my child this ill before" or "I'm concerned but I will see my child more ill than this in the future".

Researchers plan to draw on conversations with a mixture of parents, beginning with those of children without long-term health conditions who do not require regular care at hospital.
Later on, they will speak to parents and carers of children with diagnosed health conditions.
"We are hoping to gather the experiences of families and how they would describe the particular illnesses of a child," said Roland.
"We could look at the words and language that they use, and maybe help them or facilitate them to present that information in a way that might make more sense to healthcare professionals, or might be more impactful."
As well as considering language, the university is also investigating how the design and layout of hospitals might impact communication, such as desks acting as barriers.
"There is evidence to support the challenge of communication between, essentially, lay members of society - but experts in their own child - and professionals," said Roland.
"We know from other studies there is at times an imbalance in that relationship. The medical professional adopts a position of power and sometimes parents are afraid to challenge what they've been told, although in their heart of hearts they believe it's wrong."
Parents are invited to complete an online survey, before selection is made for focus groups to be held at the football club ground on 15 and 18 March.
Leicester City FC has been approached for comment.
