RESUMO
Background Although botulinum toxin (BTX) has mainly been used cosmetically and therapeutically, its field of application is expanding. So far, BTX has shown promising outcomes in the management of a wide variety of medical conditions that are difficult to treat. Objectives We assessed physicians' knowledge and experience regarding the non-cosmetic use of BTX in different clinical settings. Methods This is a cross-sectional survey that was conducted in Riyadh, Saudi Arabia, and included physicians from different specialties, with different levels of training, and from different working hospitals. Data were collected by using a self-administered survey to assess physicians' knowledge, experience, current practice, and specific training in relation to Botox administration for non-cosmetic use. Results Most participants were residents (76.19%) and specialized in internal medicine (27.62%). The majority worked in governmental hospitals (76.19%). About 73% of our sample were aware of the non-cosmetic indications of BTX, but only 44% and 55% were aware of its contraindications and adverse effects, respectively. Less than one-third (31%) of respondents administered BTX injections in their clinical practice, and about 66% of respondents had two to five years of experience giving BTX injections. The most commonly treated conditions were spastic disorders, dystonia, and then migraine. Only 4.7% and 3.6% used validated scales or instruments for planning treatment with BTX, respectively, while about 36% opted for clinical evaluation only. More experience and training in giving BTX injections significantly predicted increased awareness of adverse effects and contraindications of non-cosmetic uses. Conclusions The majority of specialty groups in our sample were aware of the non-cosmetic applications of botulinum toxin but did not use them to the same extent in their practice. Additionally, only a minority wished for further education on injection practices. The finding of insufficient knowledge about contraindications and the adverse effects of injections in a large number of participants, however, highlights the need for increased education, especially given the wide range of non-cosmetic applications and benefits that BTX can have for a variety of diseases.
