Knowledge, Attitudes, and Practice of General Practitioners Toward Screening of Age-Related Hearing Loss in Community: A Cross-Sectional Study in Shanghai, China

Background: Age-related hearing loss (ARHL) is experiencing a continuously rising in prevalence among the elderly worldwide. General practitioners (GPs) may have a unique position in its community detection and management. Objective: This study aims to assess the KAP of GPs regarding ARHL through questionnaire, to investigate the role of them in the management and to propose strategies for the hearing screening within the community. Methods: An online survey was administered to 1173 GPs, selected from 56 community health centers (CHCs) in Shanghai during April to June 2022. A scale endorsed by a panel of multidisciplinary experts was used to assess knowledge (7 items), attitudes (12 items), and practice (10 items). A mean score was computed and converted into a scale ranging from 0 to 100. Odds ratios (ORs) were calculated for potential predictors of higher levels of KAP scores (with mean value as a cutoff point) through logistic modelling. Results: A total of 1022 GPs completed the questionnaire with response rate 87.13%. The average scores are 69.90 +/- 32.27, 66.09 +/- 7.15, and 59.89 +/- 21.99 for Knowledge, attitude, and practice, respectively. 24.3% of participants achieve a complete score of knowledge, whereas 5.48% receive zero. 11.6% consider ARHL as not a disease. Above 30.0% are not familiar with the screening tool. 10.8% refuse to undergo hearing screening. Higher levels of compliance in practice are found in the participants with higher levels of knowledge (OR=1.409, p=0.000) and more favorable attitude (OR=1.028, p=0.000). Male (OR=0.708, p=0.036) is associated with lower levels of attitudes. Conclusion: GPs have a low level of ARHL knowledge, a lack of positive attitude towards the detection and management of it, and lower awareness in practice. Further research is required to gain a more comprehensive understanding of the attitudes held by GPs and explore more accessibility strategies.
