Brief

Cleft lip and palate is a birth defect that occurs when a baby's lip or palate does not form correctly during pregnancy(Dixon, 2011). Treatment of this disorder begins after birth and continues past the child’s 18th birthday. In VUMC, the multidisciplinary medical team consists of plastic surgeons, dentists, orthodontists, and nurses, give consultations to the patient and family members.

 

The consultations were conducted in the orthodontic department. The dental examination booths are not well prepared for children. To help improve the consultation experience, the design team conducted the research together and each proposed a solution targetting on a different age group. My solution is designed for baby patients aging around one year old. 

Define the problems and needs collaboratively

The direct stakeholders are young patients, parents, and medical specialists. By interviewing the medical team, our designer team learned about how the consultation contributes to the treatment from a professional perspective. Based on the field observation, we generated a journey map and corrected it with the doctor. By facilitating role-playing games with the young patients, we looked through the consultation from children's perspective.

Problems in the low-aged consultation

The problems are various in different age groups.

For the baby patient group, the typical problems are:

t1_画板 1.png

The baby pesters frequently

The dental chair doesn't fit the baby's body dimension, thus the baby has to lie on a mattress or sit with the parent during the whole consultation, which is not a suitable posture for oral check.

t2_画板 1.png

The baby feels stressed

The long duration and uncomfortableness are far beyond the baby's tolerance. The baby gets bored easily, sometimes stressed out during the invasive examinations.

Communication is limited

The parents and doctors have to take care of and comfort the baby, this leads to limited time on communication.

To add value to the consultation

  • the examinations should be more smooth and effective;

  • the baby patients should be involved with less stress and more cooperation;

  • the communications between doctors and parents should be more efficient.

Doctors communicate with parents

The dental chair doesn't fit baby's body dimension, thus the parent has to hold the baby during whole consultation, which adds challenges to the oral check.
