Confidentiality Ross Anderson Cambridge University and Foundation for Information Policy Research
The Story so Far … • 1910 – struggle over who owns medical records led to Lloyd George envelope • 1992 – IM&T strategy ‘a single electronic health record available to all throughout the NHS’ • BMA resistance 95–6 once we realised what this meant; ‘Security in Clinical Information Systems’ • Calman sets up the Caldicott Committee to postpone the issue past the 1997 election • Caldicott documents many illegal information flows; HSCA s60 allows SS to legalise them
The Story so Far (2) • ‘Pretexting’ cost Hewlett-Packard chair her job • Look back at January 1996 – Anderson RJ, ‘Clinical System Security - Interim Guidelines’ BMJ 312.7023 pp 109-111 • N Yorks HA pilot – staff trained by Alan Hassey to log info requests, get them signed off, and call back to a number you can check independently • We detected 30 false-pretext calls per week! • We asked DoH to roll this protocol out nationwide – instead, NYHA were told to stop it!
The Story so Far (3) • ‘Blair moment’ in 2002 – ‘Tony wants’ • Ray Rogers vision of the big central database is dusted off – NPfIT, CfH,… • Government really believes this is working and they now plan to roll out the same architecture to childcare, elder care, … • What are the implications for clinical confidentiality?
Issues of Scale • You can have functionality, or security, or scale. With good engineering you can have any two of these • We can live with the risks of a receptionist having access to the 6000 records in a practice – but if 20,000 receptionists have access to 60,000,000 records? • Secondary Uses Service will run unprotected for years – with a pious hope of eventual pseudonymisation • Blair philosophy is now that data will be accessible (MISC 31, ‘Information Sharing Vision’) • Misuse will be punished – pretexters will be liable for prison, though not careless HA staff (DCA CP 9/06)
Helen Wilkinson’s case • Helen is a practice manager in High Wycombe • Wrongly listed as a patient of an alcohol treatment centre • She demanded the data be corrected or removed - officials wouldn’t / couldn’t • Caroline Flint promised Parliament it had been done • It hasn’t – and the story continues…
Extending NPfIT to Kids • ‘Every Child Matters’ white paper (2003) • Children Act 2004 provided powers • Information to be shared between schools, police, social workers, probation, doctors… • The ‘SCR’ is ISA – the Information Sharing and Assessment system – which points to all services interested in your child • So schoolteachers will know if a child is known to social workers / police • IC study by FIPR (due for release real soon …)
Systems (1) – Connexions • A pilot scheme for 13-19s with ‘personal advisers’ and a card also giving discounts at HMV (better not buy Black Sabbath :-) • Pilot areas each have databases of children with health status, special educational needs, phone number etc • Contains sensitive data such as substance abuse, opinions such as risk of offending • Consent from parents not sought (‘Gillick’)
Systems (2) – IS • Information Sharing and Assessment Index – like the summary care record • Contact details – school, GP, and any interaction with police, social work, probation, specialist service • Services can mark a ‘flag of concern’ • Stigmatization issues (especially contact with some specialist services) • Celebs, abuse fugitives may be ‘stop-noted’ • Blair view: ‘might have saved Climbié’
Systems (3) – ICS • Integrated Children’s System will be the detailed record for child social work • Extends the current child protection registers from ‘child protection’ (50,000 cases in UK) to ‘child welfare’ (3-4m) • Very detailed information, from many sources, including facts, opinions and subjective judgments • There may also be a separate but similar ‘eCAF’ run by local authorities for kids who’ve been assessed but are not of interest to social work
Linked Systems • Schools – National Pupil Database, Ofsted • Justice – RYOGENS and other systems monitor kids ‘at risk’ of offending (ONSET tries to predict who will offend) • Once convicted, a wide range of probation and other systems tell officials everything (or nothing? :-) • Health – supposed to supply ‘relevant’ diagnoses e.g. early-onset hyperactivity
Social work viewpoint • It’s hard enough coping with the 50,000 kids at risk of significant harm • Adding the 3–4m kids with some disadvantage will paralyze the system • Talking about being ‘proactive’ is easy, but what does it mean on the front line? • At present, half the kids who try to kill themselves don’t get any specialist help • Left (SWM) – don’t ‘collude with youth justice policies which demonise young people’ • Right (CPS) – ‘nationalisation of childhood’
Balance of benefit and harm? • Big problem with social care is lack of effective interventions • ‘Sure Start’ program tried to implement best ideas from US research – treat the population, not individuals • Parenting classes, preschools, … • Evaluations thoroughly disappointing • ‘When all else fails, build a database’
Effects on medical practice? • Every time you come across a negative indicator, you’ll have to decide whether to fill out a CAF • At present you can do the first page and pass it to social work • The online system will make you do it ‘properly’ • What about privacy – once most customer-facing local government staff have access (plus charity workers and careers advisers, according to today’s Times)? • Doctors will be blamed for any leaks (you’ll always have to break the ‘rules’ to do your job)
Data Protection Aspects • You’ll have to wait for the FIPR report! • This compares UK practice with European law and with the practice in Germany, France etc • Comment by one observer: UK practice is on a collision course with Europe • Eventually something will have to give. Will it be Britain’s EU membership, the German constitution, or what?
Conclusions • The approach to personal data management that mutated from the IM&T strategy into the ICRS Spec into NPfIT is undergoing metastasis • Secondaries are now growing vigorously in child welfare, with more planned for elder care etc • If safety and privacy problems can’t be tackled honestly in medicine, what hope have the social workers got? • Maybe the best hope is a European law case. For details, wait for the FIPR report
