Oxleas Adult Autism Assessment Service Bexley, Bromley, Greenwich

The Oxleas Adult Assessment service offers ASD assessments to adults over 18, without a learning disability who are registered with a GP in Bromley, Bexley and Greenwich.  

The service offers a full ASD diagnostic assessment to adults who have not been assessed or received a diagnosis in childhood.  Access to the service is via GP referral, or by referral from another professional who is working with you. 

Once referred, you will be asked to complete two screening questionnaires and if the results of the questionnaires suggest that you are reporting sufficient features of possible Autism, you will be put on the waiting list for a full diagnostic assessment.

The outcome of the assessment will indicate whether the threshold for a diagnosis is met or not.  Adults would then be signposted to relevant support services as needed.  

The team is made up of a range of professionals including Clinical Psychology, Occupational Therapy, and Speech & Language Therapy. All staff have specialist training in autism assessment and diagnosis. Once the assessment begins, adults are allocated a lead clinician and the assessment will be carried out over a short series of appointments. A feedback appointment will then be arranged.

We are not commissioned to provide ongoing support to Adults with ASD and we cannot see people who already have a diagnosis.  The service operates Monday - Thursday 9am to 5pm from various sites across Bromley, Bexley and Greenwich boroughs.

Oxleas Patient Experience survey

The Oxleas Patient Experience survey gives you the opportunity to feedback on the care and treatment you have received. We also encourage your friends, family and carers to also provide feedback. Hearing your views gives us a better understanding of the needs of our patients, families and carers which helps us to make sure that we are providing a good standard of care. 

The short survey only takes a few minutes to complete and you can provide a written comment explaining what you think is working well and what is not. The Patient Experience team will collect the results of the surveys and these are shared with the relevant departments and management teams. This helps us to shape our services to continually improve the quality of the care and treatment we provide.

I have had the assessment and been told I have been diagnosed with ADHD and awaiting confirmation but I have not heard anything else and it's been a month already. I am trying to call someone to find out what is happening and if I can take any medication to help

I have been told that there is a 42 month waiting list to be seen. I have been referred by Oxleas Erith Center and met the Autism spectrum. I also struggle with sever OCD and feel let down by Oxleas having been under them for 11 years with them unable to help treat me regarding the OCD. I’m desperate for help and I have no where else to turn to. Please could you give me some information about what outcome I can expect.
Kind regards

Dear Samantha

I'm sorry that you have been unsure where to turn for help. I will be contacting you directly by email once I have all available information to address your specific circumstances in more detail. I can confirm though that we have waiting times of approximately 50 months for assessments in our Adult Autism Assessment Service.

Unfortunately, waiting times in Bexley have grown due to an increase in referrals for Adult Autism assessments but without additional funding to increase the staffing available to increase the rate of assessments. If you are unsatisfied with the wait the service suggests that individuals register a complaint with the Clinical Commissioning Group who allocate funding for health services via the contact details below:

I would like to get information regarding adult asd assessment could someone please direct me in the right direction or contact me with details provided
With thanks

I've been waiting for an adult assessment for going on 3 years since the first GP referral. When I had my initial screening, the person who called me from Bromley Oxleas NHS Trust didn't know I hadn't taken the questionnaire. Another 3 month wait. Then I received a letter in July 2019 saying the wait would be 12-14 months for my final assessment and they would let me know if there would be any delays to my wait. Fine. Obviously coronavirus happened, delays are expected. Now we are in December and I've had no contact from Oxleas. I called back in October to ask what the situation would be, was told someone would call me back. No one did. I have since tried to call a number of times to find out if I'm even still on the waiting list and what kind of wait I can expect now and the call has been disconnected 3 times. I'm at my wit's end. I can't get the help I need until I get my assessment and it feels like I'm just being left behind. This service is absolutely disappointing and incompetent from my experience. I just need help.

Dear Kat

Thank you for contacting us about your referral. We are concerned to hear the experience you have had. From the information you have provided we have endeavoured to identify the service that you have been referred to and a representative of that team will be contacting you by tomorrow on the number you have given to get more detail and to look into how we can support you and respond to your concerns.

In January 2018 I went to Erith hospital where I filled out 2 questionnaires to see whether I was on the autism spectrum and I was told I scored quite high and would need to be assessed and was discharged from Erith Hospital. As there isn't many people who diagnoses adults I was told that I would have about a 19-20 month wait. I was told that this assessment would probably take place in August 2019. I wanted to contact the people who assess autism in adults to ask whether that wait has changed but I can't find the contact details for the people who do the assessment for adults. Do you know?
