Brief summary

This study addresses whether the use of EnChroma products are feasible for use in the emergency department by color vision deficient providers.

Detailed description

This study addresses whether it is feasible for color vision deficient (CVD) physicians and other healthcare providers to wear EnChroma products in the clinical setting. It is known that color vision is important to the practice of medicine. Identifying red skin or red ear drums, noticing whether lips have turned blue or a patient is pale, and identifying colors under a microscope all are aided by or dependent upon color vision. While color vision deficiency does not preclude a person from becoming and succeeding as a physician, it may be appropriate and desired to utilize devices to improve color vision during patient care.

Interventions

DEVICEEnChroma glasses

Each participant will be provided EnChroma products to use indoors over the course of two weeks in the emergency department, educational settings, and in their personal life. They will be encouraged to wear the glasses for at least 10 hours over 1-2 weeks prior to wearing them in a clinical setting to adjust to their use, and for 10 minutes before beginning patient care as per manufacturer instructions. They will be encouraged to take specific note of clinical scenarios that require the use of color vision (e.g., - rashes, tympanic membrane erythema, stool guaiac testing, etc.).

Design outcomes

Primary

MeasureTime frameDescription
Overall Quality of Color Vision Perception Based on Patients' Description2 weeks post-interventionSubjective influence of EnChroma glasses will be assessed by asking to describe a difference that the glasses made in color vision. The overall quality of color perception will be assessed with a scale from 1 to 10. Higher score correlates highest quality (better outcome).
Overall Quality of Color Vision Perception in Normal Daylight Based on Patients' Description2 weeks post-interventionSubjective influence of EnChroma glasses will be assessed by asking to describe a difference that the glasses made in color vision perception in normal daylight based on patients' description. The overall quality of color perception will be assessed with a scale from 1 to 10. Higher score correlates highest quality (better outcome).
Overall Quality of Color Vision Perception in Dim Light Based on Patients' Description2 weeks post-interventionSubjective influence of EnChroma glasses will be assessed by asking to describe a difference that the glasses made in color vision perception in dim light based on patients' description. The overall quality of color perception will be assessed with a scale from 1 to 10. Higher score correlates highest quality (better outcome).
Number of Participants Reporting More Positive Than Negative Comments About the Use of the EnChroma Glasses2 weeks post-interventionComfort of EnChroma glasses will be assessed by a multiple choice question, where a respondent can choose from listed negative or positive responses (e.g., did or didn't like, comfortable or uncomfortable, ). Number of participants reporting more positive than negative comments about the use of the EnChroma glasses will be reported.

Secondary

MeasureTime frameDescription
Number of Participants That Reported an Impact of Using the Glasses on Patient Care2 weeks post-interventionNumber of participants that reported an impact of the glasses on patient care, especially in situations that require the use of color vision (e.g., - rashes, tympanic membrane erythema, stool guaiac testing, etc.), will be assessed by asking a question. Participants that report impact is associated with better outcome.

Number of Participants Reporting More Positive Than Negative Comments About the Use of the EnChroma Glasses

Comfort of EnChroma glasses will be assessed by a multiple choice question, where a respondent can choose from listed negative or positive responses (e.g., did or didn't like, comfortable or uncomfortable, ). Number of participants reporting more positive than negative comments about the use of the EnChroma glasses will be reported.
