How does autism affect accessing health-care appointments and follow-ups? 

Accessing healthcare is challenging for many people, but autistic individuals often face additional barriers related to communication, sensory needs, and executive functioning. According to NHS England, every autistic person is legally entitled to reasonable adjustments to remove barriers in healthcare settings. NICE CG142 also highlights that accessible communication, sensory-aware environments and structured follow-up support are essential for safe and effective care. 

Understanding the concept 

Healthcare appointments involve several steps: noticing symptoms, booking the appointment, travelling to the setting, waiting, communicating with the clinician, and understanding follow-up instructions. Each of these can be affected by autistic differences. 

Communication can be a major barrier. Autistic people may need clear, literal language, extra time to process questions, or written information rather than verbal explanations. The National Autistic Society explains that many autistic adults struggle to describe symptoms such as pain, sensory discomfort or emotional distress without adapted communication. 

Evidence and impact 

Peer-reviewed evidence shows consistent challenges. A large study published in BMJ Open by Beresford et al., 2022 found that autistic adults commonly avoid or delay healthcare because of communication barriers, phone-based booking systems, sensory overwhelm and fear of not being believed. 

Sensory overload is also a major factor. Harsh lighting, noise, crowds and unpredictable waiting room environments can cause distress or lead someone to leave before their appointment. The Leicestershire Partnership NHS Trust notes that sensory-friendly waiting options, quiet rooms and flexible arrival times can significantly reduce stress. 

Executive functioning differences add further complexity. Many autistic people find it harder to plan ahead, manage time, fill in forms or remember follow-up instructions. Missed appointments, delayed follow-ups and difficulties navigating digital systems are common not because of lack of motivation, but because organisational demands are high. 

Masking can also affect healthcare access. Autistic people may suppress signs of pain or distress to appear calm or polite, which can lead clinicians to underestimate their needs. The BMJ Open findings suggest that this can contribute to missed diagnoses, untreated conditions and preventable deterioration of health. 

Environmental barriers are widely documented. Guidance from Nottinghamshire Healthcare NHS Foundation Trust explains that healthcare services must remove or reduce sensory and organisational barriers, providing options such as quiet waiting, visual information and alternative communication formats. 

Practical support and approaches 

NHS services provide several tools to help autistic individuals prepare for appointments. The Leicestershire Partnership NHS Trust recommends using healthcare “passports” to share communication needs, sensory preferences, anxiety triggers and adjustment requests with clinicians before the appointment. These can be kept on a phone, sent ahead by email or uploaded via booking systems. 

Reasonable adjustments are a legal right. According to NHS England, examples include: 

• alternative booking options (email, text, face-to-face) 

• scheduling first or last appointments of the day 

• avoiding long waits 

• offering quiet spaces 

• providing written information for all instructions 

• allowing someone to wait outside until called 

• using simple, concrete language 

NICE CG142 further emphasises giving people extra processing time, avoiding ambiguous questions, and ensuring follow-up care is arranged in advance with clear written explanations. 

The National Autistic Society encourages people to make requests in writing before an appointment to reduce anxiety and ensure adjustments are in place. 

Digital flags are also increasingly used across NHS services. These record someone’s communication and sensory needs so that any clinician can prepare appropriate support. The Leicestershire NHS guidance explains that this can improve continuity between appointments and reduce the need for people to repeat their needs each time. 

Challenges and considerations 

There are still gaps in routine NHS accessibility. Some autistic adults report that staff assumptions, lack of training, or rigid appointment systems make it difficult to access care safely. Many do not know they have a legal right to reasonable adjustments. Others struggle because phone calls, voicemail, fast-paced questioning or changes on the day increase stress. 

Follow-up is also a challenge. Executive functioning differences can make it hard to track multiple appointments, remember aftercare instructions or manage referrals. Environmental factors such as busy receptions, unclear signage or crowded clinics can worsen anxiety and reduce engagement. 

How services can help 

NHS, NICE and NAS guidance emphasise that accessible healthcare improves outcomes. NICE CG142 recommends adapting communication, planning predictable appointment structures, reducing sensory demands and ensuring follow-up arrangements are clear and accessible. NHS England supports training staff to understand autistic needs, offering multiple booking channels and ensuring environments feel safe and calm. 

Community tools such as patient passports, digital flags, easy-read leaflets and step-by-step written plans help autistic people prepare and process information. Coaching or behavioural support programmes can also help individuals manage planning, transitions and communication demands. Organisations like Theara Change provide educational tools that support emotional regulation, habit-building and navigating systems, alongside formal healthcare services.  

Takeaway 

Autism can affect accessing healthcare appointments and completing follow-ups because of communication differences, sensory needs, executive functioning challenges and past negative experiences. With reasonable adjustments, clear communication and sensory-aware care environments, healthcare becomes more accessible, predictable and safe. Empowering autistic people with preparation tools and supportive services can significantly improve healthcare experiences and long-term wellbeing.
