Dear T Monk, 
Response to your request for official information 
I refer to your official information request received on 7 August 2018, in which you request 
the fol owing information under the Official Information Act 1982 (the Act): 
Thank you for supplying the numbers of hospital discharges with the diagnosis of 
Guillian Barré Syndrome and Motor Neurone disease.  
Could I please have these stats for a 20 year period to establish a trend 
I appreciate that whoever has replied to my inquiries has access to digital data - so 
stats over a longer period should be easily accessible.  
As far as I can see, ESR, a private company does not publicly provide long term 
results on anything. 
Given the government pays ESR it would be odd if the Ministry of Health did not have 
access to ESR data. 
Could you please check to see if ESR data is stored by the govt; in which case the 
preferred source for long term stats related to Campylobacter infections would be the 
Ministry of Health. If the govt has it or has access to ESR data on it, could you please 
supply that and the rates of Guillian Barré Syndrome and Motor Neurone Disease 
over 20 years. 

Attached is the hospitalisation information relating to Appendix One – Guillian-Barré 
Syndrome and Appendix Two - Motor Neurone Disease. Please note that as per our 
previous response to you, (H201805030) this data is a count of hospital discharges, people 
will be counted each time they are hospitalised and those people with Guillian Barré 
Syndrome and/or Motor Neurone disease that have not been hospitalised, are not included 
in the attached data sets. 
For further information The Institute of Environmental Science and Research (ESR) is a 
Crown Research Institute and is subject to the Official Information Act 1982.  
As per our previous response to you (H201805030) the information you have requested 
relating to Campylobacter is contained within the Annual Surveillance Summaries and 

Outbreak reports are publically available at the following address: 
For further information or queries relating to ESR data please contact ESR directly at 
the following email address: [email address] 
You have the right to seek an investigation and review by the Ombudsman of these 
decisions. Information about how to make a complaint is available at or free phone: 0800 802 602. 
Yours sincerely
