Databases

Using them to study MS in the UK

Proposed research using:



GPRD (General Practice Research Database)



MSNTC Northwood Database

Epidemiology



Prevalence

- how many people are living with MS?

  

Incidence

- how many people are newly diagnosed with MS every year?

Factors

region affecting MS – gender, age, ethnicity,

Trends

time – how MS epidemiology changes over

Why does it matter?

 Greater

understanding

of MS in the UK  Allocation of

resources

regionally – nationwide and  Having a

voice

– not a ‘hidden disease’

Epidemiology of MS is not well understood

 Limited information available compared to other diseases e.g. cancer, diabetes  Estimated prevalence of 85,000 by extrapolating data from a series of local studies  MS Society funded survey in 2009

UK prevalence study

June 2009



First national project based on the best evidence available



Showed that there are about 100,000 people with MS in the UK



Researchers at the London School of Hygiene and Tropical Medicine used data from the General Practice Research Database (GPRD) to estimate of the number of people with MS in the UK

What is GPRD?

 Contains patient records practices in the UK from 6% of GP  Anonymous patient data  The world’s largest primary care database  Used by academics around the world to study different diseases

GPRD published studies

160 papers 2009 to 2011 Drug treatment discontinuation and achievement of target blood pressure and cholesterol in United Kingdom primary care.

New analyses of MS using GPRD

 In collaboration with University of Dundee  Access to database  Input from epidemiologists + neurologist  Statistical analyses performed by Dr Steve Morant  Written for publication in peer-reviewed journal by Dr Glenys Bloomfield

What can GPRD tell us?

 Numbers of people with MS  prevalence  incidence  trends over last decade  Who is affected?  gender  age  region

What can GPRD tell us?

 Treatment of MS  hospital referrals  drug prescriptions  co-morbidities  GP contacts

Proposed research using:

 GPRD (General Practice Research Database)  MSNTC Northwood Database

MSNTC stats

 We already record the number of   Individual sessions of O

2

T Members receiving therapy – MS/non-MS  New members - MS/non-MS

MSNTC stats - Northwood database

 Much easier and more efficient method of collecting data  We can collect a lot more detailed information on various therapies and who uses them  Useful for fundraising and raising the profile of Therapy Centres – individually and nationally

What else can the MSNTC database tell us about MS?

 We have a major resource 

MSNTC



GPRD

~10,000 members ~ 20,000 MS patients We can learn important information about the role of non-drug therapies in symptom management

Treatment records

Treatment records can be entered for each member The system will calculate   MSIS-29 results (average answer to each question) MSIS-29 trends (improvement/no change/decline) for each question

MSIS-29 Form

Tried and tested: the psychometric properties of the multiple sclerosis impact scale (MSIS-29) in a population-based study

Multiple Sclerosis Journal January 2009 vol. 15 no. 1 75-80 The MSIS-29 is an acceptable, reliable, and valid method of recording quality of life. A significant relationship between higher physical impact scores of the MSIS-29 and higher Kurtzke EDSS values suggests that it may be of use in clinical trials to monitor progression.

MSIS-29 Form

The multiple sclerosis impact scale (MSIS-29) is a reliable and sensitive measure

J Neurol Neurosurg Psychiatry 2004;75:266 –269 The psychometric properties of the MSIS-29 are acceptable; it is a valuable outcome measure in intervention studies of patients with MS.

What can we do with this data?

 With the help of Centres and their members we can collect information on the progress of individual members over time in a format that is accepted by the medical community  When we have enough data we can analyse the effects of different non-drug therapies on the progress of MS using anonymous records from our database

Conclusions

 We have an opportunity to make important contributions to our understanding of MS using these resources 

GPRD

- epidemiology of MS in the UK, drug treatments 

MSNTC Northwood database

– role of Therapy Centres and non-drug therapies

Conclusions

 This will help ensure that MS receives the recognition and resources that it needs  It will raise the profile of the MS Therapy Centres and establish us as professional and credible members of the MS community
