OME is a common cause of hearing loss in children and adults and is a worldwide public health problem. A previous domestic survey showed that the awareness rate of parents with disease caregiving knowledge of OME was 7.09%-36.6%, and the health education needs of parents with OME were more than 50%[10]. However, this study did not conduct KAP research on OME knowledge for parents. Therefore, this study aimed to investigate and analyze the Chinese public's understanding of OME-related knowledge, attitudes and practices, understand the domestic public's demand for knowledge about the disease, and provide direction for better knowledge popularization to treat OME early.
In this cross-sectional survey of online electronic questionnaires, the knowledge, attitudes, practices related to OME and its influencing factors were observed, and the preferred sources and forms of relevant knowledge among participants of different regions, ages, genders and occupations in the Chinese mainland were collected. This study revealed that the public has a low level of knowledge, positive attitudes and positive practices toward OME, which is consistent with previous studies[7, 10].
In terms of assessing the risk factors for OME, this study revealed that infection and immature immune system status were common risk factors for OME, while early attending day care and early formula feeding were not high risk factors. Daycare, smoking exposure, and excessive use of pacifiers are also risk factors for OME, in addition to supine bottle feeding[2, 5]. Among the causes of OME, upper respiratory tract infection and allergic rhinitis were the most common. However, only 16.5% of participants chose cleft lip and/or palate (CL/P), which indicates that the participants had insufficient knowledge of CL/P as a high risk factor for OME. Soeselo et al[11] indicated that inaccurate information and education provided by medical professionals leads to insufficient awareness of CL/P among participants. Therefore, improving the public's awareness of CL/P may help reduce the prevalence of OME caused by CL/P and prevent subsequent adverse outcomes.
Although the incidence rate of OME in adults is lower than that in children, OME is also a common disease in adults, and its common causes include nasopharyngeal carcinoma (NPC) and eustachian tube dysfunction[12]. NPC is common in people in southern China, and symptoms of a lump or mass in the neck can lead patients to see a doctor. NPC can cause mechanical or functional eustachian tube obstruction, which is associated with OME. OME also presents as a complication of irradiation treatment for NPC. However, in this study, NPC and eustachian tube dysfunction (16.2% and 22.7%, respectively) were the two least common combined diseases of OME.
The symptoms of OME vary, and hearing loss is a common symptom in children with OME. The participants’ main cognition of hearing loss in children was direct performance, such as loud TV watching, and the degree of recognition of the long-term effects of hearing loss was low, such as vocabulary limitation and asking children to repeat sentences in conversation. This finding is similar to that of Parmar et al.[13] This may be related to the relatively poor long-term performance caused by hearing loss, which is not easy to detect.
For patients with OME that lasts longer than three months, tympanostomy tube insertion is the primary surgical intervention[2]. To allow the middle ear cavity to be ventilated, the tube was inserted through the tympanic membrane. The procedure is generally well accepted, with relatively rare complications such as perforation of the eardrum[5]. If surgery was indicated, 13.73% of the parents did not accept it. The top three reasons were worry about the risk of surgery, the effect of surgery, and recurrence after surgery. Therefore, it is necessary for professionals to perform surgery carefully. Chando et al.[6] reported that when clinicians respected parents’ autonomy in making decisions about the child’s treatment when appropriate, they felt respected. Gkiousias et al. [14] also emphasized that thorough communication of information to parents by clinicians during treatment consultations can impact parents’ decision-making, enhancing shared decision-making and improving clinical care.
In addition to the formulation of treatment plans, Vlastos et al.[14] reported that the disease knowledge provided by doctors is not necessarily what patients want. Parents preferred knowledge of the incidence rate, risk factors, causes, examinations, treatment and consequences; however, doctors thought that the definition, pathogenesis and surgical procedure of OME are important. This research revealed that most participants had a positive attitude toward OME, and the public wanted to obtain OME-related knowledge, focusing on the causes, hazards, diagnosis and preventive measures of OME, among which most participants chose preventive measures (76.75%). This suggests that the public aims to lower the prevalence of this disease through a better understanding of OME, which is also similar to the findings of previous studies[9, 10]. Therefore, in future education activities, medical workers should pay attention to OME preventive measures.
Similar to Meherali et al.[9] and Gkiousias et al.[15], patients' knowledge mainly comes from doctors, relatives and friends. In addition, with the popularization and development of the internet, an increasing number of participants tend to acquire knowledge quickly and conveniently through the internet, including disease knowledge[16]. Whether it is the main source of knowledge or the way to obtain knowledge in the future, the majority of participants choose new media. According to Li et al.[10], medical consultation and publicity via popular science books, the internet and other media were the preferred methods for parents of children to obtain relevant knowledge, which is consistent with the findings of this study. Gkiousias et al.[15] reported that the public is worried about the authenticity and accuracy of online information, which may be related to mixed information on the internet. It is difficult for the public without basic medical knowledge to identify the authenticity of online information. Therefore, it is important to establish a professional and reliable platform for knowledge popularization.
There was a significant difference in knowledge scores between men and women in this study, and women scored higher, which was similar to the findings of Di Berardino F et al.[17] and Alharbi et al.[18]. Alharb MM et al.[18] reported a positive relationship between education status and OME knowledge level and health-seeking behavior, but there was no significant relationship with attitude, which is different from our findings. In this study, there was a negative relationship between OME knowledge scores and attitudes, but there was no significant relationship between OME knowledge scores and health care-seeking behavior. This may be because participants with high scores have mastered OME disease knowledge to a certain extent; therefore, the education demand for disease knowledge is relatively reduced.
