Diagnosis and follow-up of concomitant diseases (comorbidities) in individuals with ASD do involve several problems [18, 19]. Based on our findings 80.6% of physicians and 63.6% of students and residents, who had to interact with patients diagnosed with ASD in their medical practice, had difficulties in the diagnosis or follow-up of concomitant disorders for these patients. These factors also resulted in dissatisfaction with the quality of medical care for children with ASD as reported by their caregivers (Figure 1). Therefore, further consideration of the key difficulties in medical service provision and possible ways to overcome them seems to be quite important and relevant.
Limited provider knowledge
Over the past decade a large number of studies have showed moderate awareness and limited knowledge among health care providers (residents and physician) on care provision and medical management of patients with ASD [20–26]. Interestingly, these results were obtained not only in developing countries (Nigeria, Turkey), but in developed ones with long histories of researching autism and extensive experience of managing patients with ASD (United States, Canada).
In Russia, based on our data, 63.5% of students and residents indicated that they did not study the signs and symptoms of ASD and the special features of managing these patients within their university/residency educational programs. It should be noted that medical faculty curriculums do contain autism teaching; however, it is a 1.5-hour lecture course without any seminars. Therefore, it is not surprising that the majority (74.2%) of non-psychiatric physicians in Russia who conduct clinical follow-ups of patients with ASD, consider their knowledge relating to diagnostic criteria, especially early diagnosis, and on concomitant disorders and correct effective interactions with a child during an examination, to be inadequate.
According to DSM5 (Diagnostic and Statistical Manual of Mental Disorders, 5th ed.; American Psychiatric Association, 2013) behavioral markers of ASD include persistent difficulties with social communication and interaction, the presence of restricted and repetitive behaviors, interests or activities. These behavioral markers were considered by less than 50% of students/residents and physicians to be the leading clinical signs of ASD (Table 1). At the same time 30% of the respondents added non-specific clinical signs such as mental retardation and the lack of emotional empathy as mandatory. Despite the established definitive criteria, more than 35% of respondents considered delayed speech or the lack of speech to be a leading diagnostic criterion of ASD, while ~10% of students/residents and ~20% of physicians consider limited eye contact and aggression to be mandatory clinical signs.

As for the diagnostic criteria of ASD, healthcare providers, it is clear that they do not always have access to competent resources. The fact that some physicians and scientific schools in Russia still subdivide psychotic forms of autism and consider ASD and schizophrenia as the same entity further aggravate this problem. Early in 2020 parent and medical communities discussed new clinical guidelines on ASD, as developed by the Russian Association of Psychiatrists. The main challenge was that the clinical guidelines are unscientific and based on out dated knowledge about autism, as were approaches to its management and rehabilitation of individuals with ASD. These issues were solved, due to active participation of parent and professional communities and in July 2020 the Ministry of Health of the Russian Federation approved new clinical guidelines on the management of children with ASD. These guidelines aimed to improve the quality of care of children with ASD and will be mandatory starting from 2022; however, medical facilities have to indoctrinate their specialists on the new guidelines and had to conduct educational activities since the time of their approval.
Medical conditions associated with ASD have been long been sufficiently studied worldwide [18, 27–35]. However, the problem of comorbidity, as well as methods of management of ASD complex behaviors, in relation to being important for effective medical care [36] are quite poorly addressed in Russian professional medical sources [37–40]. A total of 44% of physicians and 56.6% of students/residents who participated in our survey were unable to name any of common concomitant disorders in individuals with ASD. Results from the survey to health care providers investigating the most common comorbidities in patients with ASD are given in Figure 2. Given the information available, it is not surprising that 46.2% of respondent caregivers in turn mention the lack of monitoring and correction/therapy of concomitant disorders by medical specialists for their children with ASD.
In Russia activities to make physicians aware of modern studies clarifying possible mechanisms, symptoms and consequences of comorbidities in ASD, as well as methods to overcome communication barriers, are primarily conducted by non-profit organizations supported by various grant-providing systems. Recently, as the issue is important, there are more and more professional programs aimed at advanced training for non-psychiatric physicians (mainly pediatricians and neurologists). However, these programs are not always budget-funded and provide the full-time education required, that, in our opinion, make them less available and reduces the quality of the educational program in terms of physicians being able to adequately master the topic.
We consider the limited provider ASD knowledge among the Russian medical community to be due to the following problems, to which finding solutions for is vital in order to overcome this issue: (1) the educational program intended for physicians does not provide sufficient study of ASD in the multidisciplinary context or practical skills; (2) no consensus is available in relation to diagnostic criteria of ASD and the very essence of the disorder in the medical community; (3) clinical guidelines on the management of patients with ASD based on the modern diagnostic principles and treatment approaches for this condition have been quite recently approved and it will take some time for physicians to be indoctrinated with them.
Communication barriers
Impairment in communication and social interactions are defined as the main symptoms of ASD and one of the problems encountered by physicians during diagnosis of concomitant disorders. In addition, individuals with ASD are often unable to formulate complaints and may become increasingly agitated during a physical examination [41–44]. In turn, physicians may feel uncomfortable and prefer to ascribe symptoms of concomitant diseases to "common" manifestations of autism or avoid working with patients of this category at all [45]. Therefore, patients with ASD indicate low satisfaction in patient-provider communication and low healthcare self-efficacy as a result [46–48].
The above can result from insufficient skills in examination of individuals with evident behavioral disorders, indeed this has been previously shown [24, 45]. The latter is also in line with our findings, where ~75% of students/residents and physicians related difficulties in diagnosis and follow-up of comorbidities to behavioral disorders only. At least 70% of respondents mentioned the combination of the above problem with the lack of, or failed, language ability and an inability to describe a pain/discomfort experienced and their localization. At the same time only 2% of health care providers considered that additional information on effective methods of interaction with an ASD patient during an examination was required. These findings are in line with the caregivers opinion, at least 70% of whom stated that physicians who visit children with behavioral disorders are lacking examination skills. It has already been noted that health care providers can be unaware of the need to adjust their communication styles to be effective with patients with ASD - or are unable/unwilling to do it [49].
Many countries have started to contemplate what should be done in order to improve patient-provider communication [50–53]. In 2002, the American Board of Pediatrics began certifying developmental-behavioral pediatricians, whose activities involve diagnosis of developmental disabilities, identification of comorbidities, and the care assistance of these children. Results of the study conducted by Hansen et al. (2016) showed that the clinical practices of developmental-behavioral pediatricians allow them to complete the diagnostic evaluations for ASD and that the obtained multiple components of assessment align with existing guidelines [54]. In Russia and other countries multidisciplinary interaction is often suboptimal (it will be discussed in the following section) and physicians are often not aware of possible alternative communication methods or have no skills relating to the behavior and response during medical examination, preventive methods, or those of desensitization used in examination of individuals with ASD [55].
Communication is a two-sided process, therefore it should be noted that the introduction of training on compliant physical exam and common health care procedures into the program of behavior manipulation of individuals with ASD is of importance in parallel to training medical personnel in effective cooperation skills with autistic patients [56–58]. One must assume that two-sided steps would be successful and can improve the situation.
Multidisciplinary interaction
The studies conducted showed that the work of a multidisciplinary team (medical-psychological and pedagogical follow-up) facilitates better provision of care coordination and holistic service for individuals with ASD [59–61]. Combined knowledge and competence of multidisciplinary team specialists provides optimal conditions for the successful development of a child, his/her adaptation and social interactions in the community as well as allowing them to overcome difficulties including those related to heterogeneity of disorders [55, 62, 63]. Only 2% of respondent health care providers reported having a close cooperation with psychological and pedagogical specialists and not more than 10% of physicians referred to, or recommended to, consult these specialists when identifying children with ASD. The lack of multidisciplinary interaction is evidenced by answers of caregivers of children with ASD, 41.1% of whom reported inadequate post-diagnostic support including education on evidence-based methods of ASD correction.
At the same time, given the high prevalence of concomitant diseases, the follow-up of individuals with ASD by different medical specialists is required. Margaret Bauman, a pediatric neurologist, developed the first multidisciplinary program for complex care of individuals with ASD and other developmental disorders which was called LADDERS (Learning and Developmental Disabilities and Rehabilitation Services). The developed approach, under the LADDERS project based the Autism Treatment Network medical program, is a classic model to create progressive comprehensive medical care for children with ASD in many countries. In Russia the development of a multidisciplinary medical follow-up of children with ASD started in 2019 with an active participation of the non-profit organization the Center of Autism Problems. In this regard, there are great expectations for many pediatric physicians to become more aware of concomitant diseases, modern principles of their diagnosis and treatment approaches and to be trained in working with ASD individuals.
Need for Systemic Changes
A number of studies consider that systemic changes are required in order to improve the healthcare environment [23, 64, 65]. Investigators or health care providers suppose that medical care for individuals with ASD could be improved when implementing complex systemic changes such as additional finance promotion of medical professionals [60, 64, 65], reduced sensory load, and provision of additional methods of distraction in health care facilities [24]. Our survey demonstrated that 83.5% of caregivers of children diagnosed with ASD consider services on special follow-up of a child with ASD were required and at least 50% of the respondents mentioned that the environment (play grounds/rooms where a child can be distracted or sensory load be reduced) should be adapted for a successful health examination.
