Laryngopharyngeal reflux: knowledge, attitudes, and practices among primary healthcare physicians

The aim of this study was to estimate the level of knowledge, attitudes, and practices regarding laryngopharyngeal reflux (LPR) among primary healthcare (PHC) physicians in Saudi Arabia.

This quantitative cross-sectional study used an online-based questionnaire distributed to physicians in PHC facilities and hospitals in Saudi Arabia. The questionnaire consisted of four sections that provided data on demographics, knowledge, attitudes, and practices.

Of the 473 physicians included in the study, one-third were unaware of LPR, and two-thirds were unfamiliar with the reflux symptom index (RSI). The most common sources of LPR knowledge were textbooks and literature (49.8%). The most recognised risk factor, symptom, and complication were high body mass index (75.8%), voice problems (82.4%), and laryngeal cancer (70.6%), respectively. The most recognised diagnostic and treatment options were laryngoscopy (73.5%) and lifestyle modifications (87.3%), respectively, while only 60.4% of participants recognised proton pump inhibitors as a treatment option. Most PHC physicians believed that LPR is underdiagnosed and that primary prevention and awareness among the general population need to be improved.

One in three PHC physicians knew nothing about LPR, and two in three were unfamiliar with the RSI. More than half could not recognise all major symptoms of LPR, which might be a cause for concern, as recognising these symptoms is crucial for proper diagnosis. We recommend increasing the education of physicians about LPR, its signs and symptoms, and the RSI, all of which provide valuable clues for diagnosis.
