Abstract

We aimed to investigate neurophobia among primary care physicians. This study is designed as a descriptive and analytic research. At the 5th-7th meetings of the Family Practice Academy Research Days, volunteered 425 primary care physicians participated in this study. They had answered a questionnaire investigating the participants' interest, knowledge, professional confidence and perceived hardness of neurology by comparing it with other 10 speciality. They replied about the frequency, knowledge, professional confidence and referral rate of several neurological problems/diseases they encounter while practicing in primary care. Lastly they stated their opinions about possible reasons for perceived hardness in neurology with possible solution methods which might help them improving their neurology knowledge and skills. The participant's knowledge level (F=12.063, p<0.001), personal interest (F=8.795, p<0.001) and professional confidence (F=9.245, p<0.001) were lower than cardiology, dermatology, endocrinology, gastroenterology, nephrology, respiratory and rheumatology compared with neurology. They also perceive it harder compared to these specialities (F=10,214, p<0,001). The expectations were oncology and haematology. Need to know neurophysiology/anatomy, complexity of neurology and the rareness of the opportunity to work with a neurologist is the most common reasons for neurophobia. Headache was the most common problem that they encountered (F=8,512, p<0,001), while they have got the highest knowledge level (F=6,474, p<0,001), professional confidence to manage it (F=3,214, p<0,001) and had lowest referral rate (F=9,521, p<0,001). As conclusion, neurophobia is present inexperienced primary care physicians. Our results must be confirmed and interventional studies are needed to eliminate this condition in primary care.

Introduction

Primary care physicians, who are the first point of contact for most patients with neurological disorders, take on several responsibilities in the initial diagnosis and management of a broad range of problems affecting the nervous system [1]. It has been estimated that 20% of patients applying to primary care physicians have neurological complaints and 9% of the daily workload of a primary care physician is devoted to the evaluation and management of diseases of the nervous system [2-4]. However, family physicians might feel uncomfortable and dislike dealing with neurological problems and disorders [5]. Primary care physicians consider their neurology knowledge less satisfactory compared to the subjects related to other systems [6]. They also perceive neurology more difficult than other specialties [6]. The frequency and severity of this problem are higher than expected [7]. In 1994, Jozefowicz [8] coined the term 'neurophobia' for this phenomenon. According to Jozefowicz, neurophobia is "fear of the neural sciences and clinical neurology that is due to the students' inability to apply their knowledge of basic sciences to clinical situations." Neurophobia may range from disliking patients with neurological problems to avoiding clinical management of these patients and dismissing them as quickly as possible [9]. In severe situations, physicians report paralysis of thinking or inability to take action in patients with neurological problems due to the loss of self-confidence [10,11]. Neurophobia and missing information can lead to misdiagnosis.

To investigate neurophobia among primary care physicians in Turkey, we designed a study based on the four aspects of Kern's approach to curriculum development (problem identification, needs assessment for targeted learners, instructional strategies, and evaluation/feedback) [12]. We prepared a questionnaire to compare the primary care physicians’ attitudes and beliefs towards patients with neurological disorders and those with diseases of other internal specialties. We investigated the frequency of several neurological problems/diseases they encounter, their professional confidence in managing these patients, and the referral rate. Lastly, we examined the reasons for neurophobia (if present) in family physicians and their recommendations that could help to overcome this problem.

Patients and Methods

Study design

This study was designed as a descriptive and analytic research. The research was conducted at the 5th, 6th and 7th the Family Practice Academy Research Days, which was held in different cities of Turkey (Canakkale, Ankara, and Hatay) from May 2014 to April 2015 with six months interval. In these meetings, primary care physicians from all parts of the country met for scientific activities. The primary care physicians attending the meetings were informed about the aim of this study and provided with the questionnaire. A total of 425 primary care physicians participated in the study (response rate 82.5%). The questionnaire was based on the recent literature on this topic [5-17].

The questionnaire

The questionnaire started with investigating demographic and professional features of the participants. In the first part of the questionnaire, the participants' interests, knowledge, professional confidence and perceived hardness in neurology compared to other ten specialties (cardiology, dermatology, endocrinology, gastroenterology, nephrology, neurology, respiratory, rheumatology, hematology, and oncology) were investigated. Each item in the questionnaire was evaluated with a 5-point Likert scale (1=very low, 5=very much). In the second part, we questioned their knowledge and professional confidence related to different neurological problems/diseases. Besides, the frequency of patients with neurological disorder and referral rate in these patients were also inquired in this section. These items were evaluated with a 5-point Likert scale (1=very few, 5=very frequent). In the last part, the participants stated their opinions on possible reasons for perceived hardness in neurology and which learning method might help them improving their neurology knowledge and skills. These items were evaluated with a 5-point Likert scale (1=unimportant, 5=very important).

Statistical analysis

We used SSPS version 15.0 to analyze the data. A p value of < 0.05 was accepted as statistically significant. The averages of each item (knowledge, interest, professional confidence and perceived hardness) were calculated using scores obtained from the 5-point Likert scale, and they were accepted as dependent variables. In different items, the statistical relationship between two specialties was investigated with paired samples t-test. To investigate the relationship between these specialties and neurology in different items, we used repeated measures analyses with a post-hoc Bonferroni test for multiple comparisons. The knowledge, professional confidence, frequency, and referral rates of several diseases/ problems that primary care physicians encounter were also analyzed with repeated measures analyses with a post-hoc Bonferroni test for multiple comparisons. The mod, median and skewness were also calculated, where needed. Cronbach's alpha was used to verify reliability in each item sets.

Ethical issues

The study protocol was approved by the Ethics Committee of Ondokuz May?s University.

Results

A total of 425 primary care physician participated in the study. There were 250 (58.6%) females and 175 (41.4%) males. They have been working as a primary care physician for 7.71 ± 6.41 years. There was a significant difference between the male (10.11 ± 6.59 years) and female (5.98 ± 5.74 years) practitioners in terms of the years of practice as a primary care physician (t=3.093, p=0.003).

Knowledge, interest, difficulty and confidence

The mean of the Likert scores in knowledge, personal interest, perceived difficulty and professional confidence in different specialties, and their comparison with neurology were presented in Table 1. The repeated measures analyses comparing neurology with other specialties in terms of knowledge, interest, confidence and perceived hardness were shown in Table 2. These results indicate that primary care physicians’ knowledge level, personal interest, and professional confidence in neurology were lower than cardiology, dermatology, endocrinology, gastroenterology, nephrology, respiratory and rheumatology. They also perceive neurology harder than these specialties. Primary care physicians' knowledge level, personal interest, professional confidence and perceived hardness were similar with hematology. The oncology scores for knowledge level, personal interest, and professional confidence were lower than neurology while they perceive oncology harder than all of the compared specialties including hematology and neurology. The internal reliability analyses revealed Cronbach alpha value for knowledge 0.87 (Item-total correlation was between 0.321-0.608), personal interest for 0.83 (Item-total correlation was between 0.402-0.612), perceived difficulty for 0.84 (Itemtotal correlation between 0.472-0.618), and professional confidence for 0.88 (Item-total correlation between 0.271-0.510).

The factors related to perceived difficulty with neurology

The mean scores of the various factors related to perceived hardness in neurology were presented in Figure 1. More than 50% of the participants identified the need to know neurophysiology/anatomy, the complexity of neurology, and the rareness of the opportunity to work with a neurologist as important or very important factors. The Cronbach’s alpha value for these set of questions was 0.88 (Item-total correlation was between 0.351-0.658).

The neurological problems/diseases workload of primary care physicians

The most common neurological problems/diseases encountered by primary care physicians, their knowledge related to neurological disorders, their professional confidence in the management of these disorders and their referral rate to secondary or tertiary health care were presented in Table 3. In this table, the statistical relationship between each of the neurological disease/problem's means of four items (frequency, knowledge, confidence and referral rate) were presented. Compared to others, headache was the most common neurologic problem encountered by primary care physicians (F=8.512, p<0.001). While they had the highest knowledge level (F=6.474, p<0.001) and professional confidence (F=3.214, p<0.001) in managing headache, the referral rate was lowest for headache (F=9.521, p<0.001). Many diseases/ problems had higher referral rates than expected (vertigo, neuropathies, and epilepsy, etc). The scores of four items were statistically different in headache, epilepsy, cerebrovascular diseases, neuropathies, vertebral disorders, neurological infections, Alzheimer diseases, vertigo and sleep disorders.

The factors suggested to improve neurology training of primary care physicians

The mean scores, median, mode, and skewness of methods which may be useful for improving neurology training were presented in Table 4. Most of the participants considered peer education, bedside tutorials and neurology rotation as the most important methods of improving neurology education. Cronbach’s alpha value for these items was 0.82 (Item-total correlation was between 0.279-0.609). Of the participants, 112 (26.3%) filled the free text section of the questionnaire. Implementation of teaching days during scientific organizations (n=61) live and free neurological consultation lines, or websites (n=42) were the most common themes in these open text suggestions.

Discussion

After the introduction of the term ‘neurophobia,' several studies from distinct parts of the world have investigated this phenomenon [12-16]. Participants of these studies were selected mostly among the medical students and the residents of family physician programs [6,7,9-11,13-16]. To our best knowledge, however, we conducted the first study that investigates neurophobia in clinically experienced primary care physicians. Our results revealed that neurophobia is an unpleasant fact for primary care physicians. The primary care physicians who had participated in our study stated that they had less knowledge, interest and professional confidence in neurology compared to other specialties. They also perceived neurology harder than other specialties. Although there are several studies which confirm our results [6,7,10,13,14], Flanagan et al. [9] find out that primary care physicians rank their neurology knowledge at the third lowest level after geriatrics, rheumatology, and nephrology. We also add oncology and hematology to the list of other specialties that were compared with neurology. So far these two specialties are neglected in former studies on the same topic. Interestingly our results revealed that when compared with neurology not only primary care physicians got similar scores in hematology; they got less knowledge, interest, professional confidence and higher perceived hardness for oncology. This finding is interesting, and we need more data to offer an explanation.

The primary care physicians are expected to accomplish different clinical roles (prevention, diagnosis, treatment, rehabilitation, etc.) for a broad range of neurological diseases/ problems. Therefore, it is essential for them to be comfortable with dealing with the diseases of the neurological system. To reveal family physicians attitudes towards several clinical neurological problems/diseases, we asked the frequency, professional confidence, knowledge and referral rates related to each neurological disorder. Then, we analyze the relationship between these four items in each disease/problem. In agreement with the data of WHO [18], the most frequent three neurological problems encountered by primary care physicians were headache, epilepsy, and dizziness respectively. Our results showed that the frequency, knowledge, professional confidence and referral rates of each of the diseases might be different from each other. For instance, there was a difference between the referral rates and frequency and between the referral rate and knowledge for headache; this difference was statistically significant. This result can be interpreted as increasing knowledge levels resulted in a lower referral in headache patients. Additionally, there was a significant difference (negative correlation) between the referral rate and knowledge and between the referral rate and confidence in epilepsy and cerebrovascular diseases. This result can be partly explained with the condition that as most of the time primary care physicians learn after a patient had a cerebrovascular event. However, the role of primary care physicians in preventing a relapse of a cerebrovascular event can be best achieved in primary care by regulating risk factors (blood pressure, diabetes, etc.) [19]. The results related to epilepsy are also disappointing since most of the convulsive conditions, except certain conditions like status epilepticus, can be diagnosed and treated in primary care [20]. There was a statistically significant difference (negative correlation) between the referral rate and frequency in neuropathies, vertebral disorders, neurological infections, Alzheimer’s disease, vertigo and sleep disorders. These results couldn't be just explained by the limited clinical role of primary care physician in several diseases (Alzheimer’s disease, Parkinson’s disease, etc) but they are alarming as they could be interpreted as primary care physicians tend to refer most of these patients. For example, the primary care physician's role in early diagnosis, screening, and assessment of daily functions, behavioral symptoms, and caregiver status is vital in dementia [21,22].

The second aim of this study was to determine possible reasons for neurophobia in primary care physicians. The several factors for neurophobia which are discussed in the previous studies can be divided into three main groups (undergraduate and postgraduate neurological training and others) with regards to primary care [6-11,13-15]. Among these factors, one of the most important factors for neurophobia is the perception of neurology depending on a stereotypical point of view to neurology specialists, and neurological sciences of primary care physicians and patients were claimed [17]. However, our results showed that many of our participants (36%) don't believe neurology's reputation as a tough subject is an important factor for neurophobia. The other factor that is discussed previously is the highly specialized and specific content of neurology [13,14]. For instance, to diagnose, treat and follow-up headache a 30-step algorithm is needed [23]. Most of our participants believe that neurological diseases are progressive with no special treatment. It is not easy for a primary care physician to understand and to explain several neurological diseases and problems such as multiple sclerosis and motor neuron diseases to the patients [11].

Neurophobia often starts during undergraduate medical education. Most of our participants (>50%) stated that undergraduate neurology training is far from satisfactory and it focuses on rare diseases. Also, they stated that they had limited time and clinical experience. Many of them believe that neurologic physical examination is too complex. One of the main concerns about the factors causing neurophobia in undergraduate education is that neurological training mostly focuses on detailed, comprehensive and complex neuroanatomical and neurophysiology for basic physical examination and diagnosis, which is also confirmed by our participants [14]. Parallel to our results, participants in several studies demand improvements and simplification in neuroanatomy and physiology education [9]. The other common concern of the participants in our study was the ineffective bedside tutorials. In several studies, limited bedside tutorials and patient exposure were also brought to attention [14,15,23]. Warlow et al. [23] pointed out that small group of students instead of larger ones is the critical factor for the efficacy of bedside tutorials. In addition, to increase the efficiency of bedside tutorials, experimental learning circle models are defined [24]. In this model, four components (active experimentation, concrete experience, relative observation and abstract conceptualization) are linked with each other.

Furthermore, there is substantial evidence that primary care physicians can't benefit enough from their postgraduate neurological training [6,25,26]. Residents mostly have to depend on their fundamental undergraduate neurological training for their clinical workload. Our results confirm this situation as most of our participants believe that their postgraduate neurology training and their clinical experience with neurologic patients are limited. To increase the affectivity of neurology training in residency programs, our participants underlined once again the importance of bedside tutorials with neurologist supervisors, similar to undergraduate education. Most of the participants in our study stated that a neurology rotation, neurological clinical skills training, and lectures would be very useful. It is not surprising that problem-based learning is not so much popular although it was recommended in several relevant studies [27,28]. Problem-based learning is a new concept in Turkey, and only a handful of primary care physicians had the opportunity to experience this learning so far. The web-based learning was not popular in our study compared with other methods although several researchers underlined the possible benefits of using virtual patient cases with e-learning [27,29,30]. To set minimum standards, several family physician organizations recommend curriculum guidelines for neurology. However, each residency program is mostly responsible for its curriculum [31]. Some researchers stated that this training must include simple, integrated and cooperative content but most importantly it must concentrate on the clinical experience of the primary care physicians [32]. To identify the needs of primary care physicians, the residency curriculum designers must have accurate and detailed data on the neurology workload in a primary care setting.

Must-know guidelines are also developed to help first-line primary care physicians in several crucial topics. Our study also revealed that primary care physicians demand high cooperation with neurologists (consultation lines etc.) with specialized training.

However, our study has some limitations. First of all, the participants in our study have graduated from different medical universities, and it is possible if any of these universities have favourable conditions for neurology training for primary care. Our results based on subjective variables highly depending on participants. Although the participants in this study were selected from primary care physicians who were working in different cities of Turkey, these results can't be generalized.

In conclusion, our results indicated that "neurophobia" is present in the primary care physicians. The primary care physicians demand a better neurology education at both undergraduate and post-graduate levels, besides, liveconsultation capability with neurologists in special occasions. Similar studies are needed to confirm our results in primary care. The next step must be interventional studies with high reliability and validity to reduce neurophobia among primary care physicians [16,26].
