Un-tapping key patient information from free-text data (April 2019)

In a new article published in Open Access Government, Goran Nenadic argues for using patient information stored in routinely collected healthcare free-text data.




 

Sharing your free-text healthcare data safely (March 2019)

Clinical information written in patients’ medical notes contains a wealth of information which could be unlocked for research to improve health and wellbeing. Researchers are often refused access to this written text because of concerns about privacy breaches. Healtex, the research network for healthcare text analytics, are seeking to draw up a national framework for data governance and safeguards for the acceptable use of medical free-text data from patient records within research for public benefit.

This workshop focuses on gaining feedback from the public on a range of safeguards which could be put in place to enable your medical data to be shared for research, whilst keeping your identity and privacy safe.

The workshop is co-organised by The Alan Turing Institute and Healtex in London on March 28th, 2019. Applications and details are available here.

   


 

Citizens’ jury on using free-text healthcare data for research (April 2019)

HealtexBrighton and Sussex Medical School and Citizens’ Juries c.i.c. organised a three-day citizens’ jury in June 2018 to understand whether, and under what conditions, the public would accept medical free text data being used for research. The citizens’ jury with 18 people, comprising a cross-section of the public, have learnt from expert witnesses over three days about structured and unstructured health data, and the challenges, needs and opportunities in processing free text data. The jury deliberated together, exploring the complexities and potential trade-offs between privacy and the public good, and reached reasoned conclusions about whether and under what circumstances use of free-text data for medical research can be justified. This was the first study to ask the public what they think about de-identified clinical narrative being used for secondary purposes.

The outcomes of the jury are available here and include a short and full reports, video and a brief leaflet.

 


 

Working group: Text Mining Radiology Reports (March 2019)

At the beginning of March, we held a Healtex working group meeting for Text Mining Radiology Reports in the Bayes Centre in Edinburgh. This was an excellent opportunity to bring together teams with a shared focus on improving health services through a better understanding of radiology reports. All teams brought different insights and thoughts to the table about challenges they face. We discussed several topics, including standardising reports and their annotation, linking annotations to ontologies, e.g. UMLS or SNOMED CT, comparing rule-based, machine learning and deep learning methods, data governance protocols, working with systems on locked down infrastructure and availability of different tools and knowledge resources. More details are available here.


 

Processing veterinary electronic health record – the SAVSNET project (February 2019)

Our partners from SAVSNET and HeRC have released a short video explaining how they use veterinary electronic health records for monitoring disease trends over time, and provide data resources for academics and others to improve health of our pets.

 


 

Working group: NLP for mental health research (January 2019)

The first meeting of the Working group on Natural Language Processing (NLP) for Mental Health Research was held in London on Jan. 15th 2019. In this meeting, the group discussed ongoing projects in this area and identified challenges and potential collaboration points for advancing the field. In the UK, there are several research groups working in this area, and we hope for this working group to become a place for sharing experiences and enabling further cross-institutional collaborations. More details are available here.

  • Towards Shareable Data in Clinical Natural Language Processing: Generating Synthetic Electronic Health Records (J. Ive, S. Velupillai, N. Viani, A. Roberts, R. Stewart, S. Puntis, W.O. Pickrell, R.N. Cardinal)
  • AuTomated prioRitisation and categorIsation of sAfety and PharmacoviGilance Events in CTIMPs (TRIAGE) (I. Spasic, M. Busse, A. Balinsky, D. Owen, C. Johnson)
  • Developing data governance for using free-text data in research (TexGov) (K.H. Jones, E. Ford, N. Lea, D. Ford, S. Thompson, A. Lacey)
  • Automated coding of Free Text to Clinical Ontologies (A. Lacey, S. Thompson, O. Pickrell, B. Fonferko-Shadrach, S. Dobbie, A. Roberts)

 


 

Savsnet’s 10th birthday (October 2018)

To mark ten years of The Small Animal Veterinary Surveillance Network (SAVSNET), an event was organised to showcase the research being done using electronic health data from veterinary practices and laboratories, and how it is informing primary veterinary practice. A lot of data that SAVSNET collects is in free text – that’s why text analytics is an integral part of their processing workflow. Details of the event are available here and HeRC blog is here.

 


 

Healtex datathon on ADR identification from Social Media (Sept 2018)

Healtex and HealthUnlocked co-organised a datathon on adverse drug reaction mining from social media post, which took place in London on September 28th, 2018. A team of 17 participants from the universities of Manchester, Sheffield, Brighton and Sussex along with the hosts from HealthUnlocked spent the full day analysing and discussing the current state-of-the-art and challenges in the identification of key elements of automated pharmacovigilance using social media.

 

The datathon was part of a Healtex feasibility study that’s looking into how much information required for Yellow Card reports is present in social media posts. Yellow Card is a scheme used by the Medicines and Healthcare products Regulatory Agency (MHRA) to monitor the safety of all healthcare products in the UK.

The participants, including clinicians, text and data miners, qualitative researchers and user engagement experts, worked with an annotated dataset of 200 posts from five communities present in HealthUnlocked to establish the feasibility of automated extraction of the core Yellow Card data (e.g. treatment indication, drug, side effect, severity, outcome etc.). After an exciting and exhausting day of coding and discussions, we were able to identify a number of challenges that would require additional work to make the results of text mining of patient-generated data applicable in real-world applications. The participants also looked at a wider context of how to support better and more efficient reporting of ADRs to regulatory bodies.

Here is a brief video that reflects on the datathon aims.

 

 


 

HealTAC 2018 (April 2018)

Medical Confidentiality: When is it OK to use your Patient Records in Research (January 2018)

Healtex and the Brighton and Sussex Medical School organised a discussion event to discuss the following questions with the members of public: Do you know what’s in your medical record? Have you ever thought how information about your care and outcomes might help others? Where should we draw the lines between privacy and making use of data for better care? Some data is harder to make anonymous such as letters written between GPs and specialists, scan reports, and doctor’s notes about patients’ symptoms, and so is often not included in a data set used by researchers. We wanted to know what the public views on medical data that is harder to make anonymous being used for research. The event involved learning more about research using NHS patient data through presentations from medical researchers, doctors, law and public engagement specialists, as well as roundtable discussions.
