Abstract
Introduction
Potassium hydroxide (KOH) is an inorganic keratolytic test. It is considered one of the most worldwide methods used in the dermatological field with reasonable reliability and sensitivity. One of its major uses is in identifying fungal elements in the skin, hair, nails, and different body secretions. In this study, we aimed to identify the prevalence of KOH usage in different hospitals in the Al-Ahsa region, Saudi Arabia. Additionally, we aimed to identify the dermatological conditions in which KOH is being used and practiced by physicians.
Methods
This was an anonymous questionnaire-based cross-sectional study that was distributed and carried out among dermatologists in Al-Ahsa city in the Eastern province of Saudi Arabia.
Results
A total of 30 dermatologists completed the study questionnaire. Participants’ ages ranged from 29 to 59 years old with a mean age of 39.5 ± 11.4 years old. 14 (46.7%) dermatologists reported that the KOH test is available in their clinic. Using KOH once a day was reported among 14.3% while 21.4% used it once a week. The most reported condition for KOH use was hair dermatophytes (100%).
Conclusion
There is a clear lack of usage and availability of KOH in clinics. The shortage of availability of diagnostic tools, including KOH might affect the diagnosis of several diseases and may cause a waste of resources, wrong prescriptions, and patient’s burden.
