The UK government is building a national database of medical records, a
project which many doctors oppose; in a Medix poll in November, over half ofall GPs said they would not upload their patients’ data without consent  .
The following week, a Joseph Rowntree Reform Trust poll revealed that 53% ofpatients oppose a central medical records database with no right to opt out.
A campaign, TheBigOptOut.org, was launched on the back of that poll to
persuade people to write to their GPs opting out of having their data uploadedto the ’Spine’ .
Controversy followed quickly when the Chief Medical Officer wrote to GPs
telling them to report dissenters to the Secretary of State, a move that the BMAcondemned as a breach of patient privacy . Meanwhile, a Department of Healthconsultants’ report criticised plans to protect sensitive data on the Spine usingso-called ’sealed envelopes’ . So what effect might the NHS’s National Programfor IT have on patient confidentiality, in the particular context of substanceabuse?
Some historical background may be useful. The NHS ’IM&T Strategy’, launchedin 1992, had the stated aim of ’a single electronic patient record, accessible toall in the NHS’. Once the implications had sunk in, the BMA objected, andthere followed a high-profile debate in 1995-6 about the permissible extent ofelectronic information sharing.
I was commissioned by the BMA to write ’Security in Clincal Information
Systems’, a policy setting out how the safety and privacy of clinical informationshould be managed . The nub of the debate was that the BMA (and theGMC at that time) insisted that the patient have control – that patient consentoverrode all other considerations except in a small number of exceptional casesdefined by existing law.
The BMA policy therefore set out how patient consent could be implemented
in real systems; it turned out that this policy, and similar ones, could deal per-fectly well with access controls in the immediate care environment. For example,a clinical information system developed by System C and used in a number ofUK hospitals adopted a form of role-based access control to restrict record accessto staff in a patient’s ward or department .
The Department of Health, on the other hand, rejected patient consent and
insisted that access should be based on ’need to know’. While ’consent’ and’need to know’ may be kept more or less synchronised in the immediate careenvironment, their effects diverge greatly when it comes to secondary uses ofclinical data.
A health service manager may decide that he ’needs to know’ all diagnoses
of alcoholism in the UK, to monitor care costs; does his ’need’ prevail over thewishes of a patient who has told his GP in confidence of an alcohol dependancy?
In the days of paper records the problem did not arise, or was at least not
so acute, as the department of Health normally only got its hands on the recordafter the patient was dead – and so could no longer sue for breach of confidence.
One interesting episode in 1996 was a demand that the police be given ac-
cess to the database of the Prescription Pricing Authority. The Department ofHealth argued that they needed this in order to catch the occasional doctor whomisprescribed heroin. The BMA objected but eventually decided that this wasnot an issue on which it was prudent to fight a major battle. The police got theirdata; but this did not stop Harold Shipman murdering dozens more people.
In any case, the conflict between consent and ’need to know’ for access was
referred to the Caldicott Committee, whose report discovered dozens of illegalinformation flows within the NHS . For example, supposedly de-identifieddata relating to treatment for HIV was being re-identified, creating identifiablerecords on HIV/AIDS patients at the PHLS, without the patients’ knowledge(let alone consent). The eventual response of the Government was the Healthand Social Care Act 2001 which allowed the Secretary of State to declare anyflow of health information to be legal, regardless of objections under the law ofconfidence or data protection.
Having decided in principle that administrative ’need-to-know’ overrode patientconsent, the Government found the path clear to launching the National Programfor IT in 2002.
This envisaged all clinical records in England moving to a national system,
with hospital and GP records being kept on centralised systems by contractors– ’Local Service Providers’ (LSPs) in five regions, and some further nationalapplications spanning the whole of England. Contracts were let and the programbegan in 2003.
Hospital systems are now being migrated en masse to approved new systems
provided by the LSPs. This has led to many operational problems. For example,the fact that systems are ’hosted’ – that is, the patient data from records toX-ray images are kept at an LSP hosting centre rather than at the hospital itself– makes operations critically dependent on the availability of the hosting serviceand of the communications to it.
One of the first hospitals to be ’rolled out’ to the new system, the Nuffield
Orthopaedic Centre NHS Trust in Oxford, lost a day’s operations after a powerfailure at its hosting centre.
A future failure of the Internet could thus leave England’s hospitals without
access to medical records and radiology images, reducing them to operatingunder field-hospital conditions. There have also been many schedule and budgetoverruns, with one of the key LSP contractors leaving the program.
Problems with the new systems are so pervasive and severe that a group of
23 professors of computer science (of which I am a member) has called on theHealth Select Committee to review NPfIT; and recently the responsible minister,Lord Warner, has resigned.
The case of Helen Wilkinson is instructive. A GP practice manager in HighWycombe, she found that she had been wrongly entered on central systems as aformer patient of an alcohol abuse service. She objected and experienced greatdifficulty in getting the incorrect data changed or removed. In the end her MPcalled an adjournment debate in the House of Commons at which health ministerCaroline Flint promised that the data had been removed, and that Mrs Wilkinsonwould continue to have access to NHS care in future. (The system in question,the NHS Secondary Uses Service or SUS, contains summaries of all secondarycare episodes; it is used for research and for health service management taskssuch as helping answer parliamentary questions.)
Some time later, when the data had actually been removed, it transpired
that Mrs Wilkinson could not receive NHS care without further central recordsbeing created. She has since started a campaign (www.TheBigOptOut.org) topersuade patients to opt out of central data sharing .
The immediate target of TheBigOptOut.org’s campaign is a plan to upload a’summary care record’ of each patient in England to the NHS Care RecordsService (CRS). This will be followed in due course by further data. Ministers’vision is that CRS will eventually include all NHS medical records, both hospitaland GP, in England. Within a few years, these are all supposed to be hostedon systems run by the LSPs, and so they can be joined up to provide a singlerecord supporting seamless care in accordance with the 1992 vision.
It is claimed that privacy concerns will be dealt with by means of role-based
access controls, which will limit record access to clinicians who claim to have acare relationship with the patient. In practice this will mean checking a popupthat says ’Please confirm that this patient has given you consent to view theirshared record’; checking this box is bound to become a reflex action for clinicalstaff.
For sensitive data there will be ’sealed envelopes’. A recent presentation about
these is blatant about their purpose: they are to ’build confidence’, to ’dissuadepatients from dissenting’ and to ’enable sharing of PSIS messages’ . If aclinician outside the care group accesses sealed data, an alert will be sent to thegroup’s privacy officer.
There is a further option for a record to be ’sealed and locked’ whereupon
clinicians outside the care group will not be aware of the record’s existence . There is a suggestion that GUM clinics will generate data that is ’sealedand locked’ by default.
However, other systems will have access to sealed and locked data; access will
be granted where the law demands it, and data will be collected for use by theSUS. (SUS data will in time be ’anonymised’ but as this means merely replacingyour name and address with your postcode, date of birth and NHS number, thelevel of privacy provided is risible – as Caldicott pointed out.)
To facilitate such secondary record access, sealing will be accomplished by
marking the data using HL7 codes created for the purpose, rather than by (forexample) encrypting the data using a key kept on a patient card.
Sealing thus provides a rather strange form of privacy. If you seal your data,
any other clinician can still get access to it; while if you seal it and lock it, someclinicians involved in your care will be denied access to it, but civil servants andresearchers will have access as before.
Not only does this arrangement offer the appearance of privacy, rather than
its reality, but so do the proposed mechanisms for ’opting out’ of the upload ofGP records to CRS: the approved protocol is that the GP will upload the relevantrecords for all patients, and then further upload a blank record in respect of eachdissenter (whose actual records will also be retained centrally).
Thus all medical records in the UK will be available for DoH purposes. What
about other arms of government, such as the police?
There will be some restrictions on police access – CRS records should countas ‘excluded material’ under the Police and Criminal Evidence Act (PACE),so police officers have to jump through slightly more hoops to get access to it.
However, access can still be obtained if they can show that the material is likelyto be relevant evidence, and this may be particularly relevant in the case of drugusers.
There is a further data feed in prospect to the Home Office ’ONSET’ system
that tries to predict the likelihood that young people will offend. This systemharvests, from a wide range of sources, data that are correlated with offending –which may include local social deprivation, school behaviour reports, a historyof parental imprisonment, and relevant medical diagnoses such as ADHD.
This data collection has been criticised in a report to the Information Com-
missioner as likely to stigmatise children unjustly and quite possibly in breachof European human-rights law .
If this system survives the Information Commissioner’s scrutiny and any
subsequent third-party legal challenges, it is difficult to see how information ondrug and alcohol use from CRS will not be used as an input. Child welfare systemmanagers will want not just records on drug and alcohol abuse by youngsters,but also by their parents or carers.
In addition to SUS and CRS, a final concern is HealthSpace, a proposed
system to enable patients to see and comment on their own medical records.
There is a concern with such systems that vulnerable patients will be bullied intoacquiring access (which could be as simple as requesting a password through thepost) and then into disclosing information, for example to relatives or employers.
The challenges to patient privacy in the field of drug and alcohol rehabilita-
tion are thus potentially severe. To sum up, let us consider how two particularthird parties – a police officer, and a private detective – can get access to apatient’s treatment history.
Police and commercial access to medical records
In the case of the police, there has been access since 1996 to the PrescriptionPricing Authority, and so a prescription for Antabuse, disulfiram or methadonecan be picked up (though only the third of these is thought to be of interest atpresent). Access can be obtained to medical records already, but it is difficult asa practical matter.
At present, the investigating officer would have to locate the suspect’s GP,
get a Crown Court judge to sign a PACE production order, and then take itround to the surgery. Even so, the desired data might not be present at thesurgery, as the suspect might have been treated in hospital.
In future, each police force will have a single point of contact with the CRS
administrators at each LSP, and – if the arrangements made already with phonecompanies are any guide – data access will be largely automated and very con-venient.
Access for specific purposes, such as identifying children thought likely to
offend, may be fully automatic and built into the infrastructure, rather thanrequiring a production order for each case.
The private detective’s life will also be much easier. At present, the main way
to gather personal health information is ’pretexting’ – phoning up someone at ageneral practice of health authority who has access to the data and telling someplausible untruth over the phone, such as pretending to be a doctor involved inthe target’s emergency care. At present, this is also inconvenient as the detectivehas to figure out which GP or health authority to call.
However, once all health service staff have access to all patients’ records,
all it will take to access an unsealed record will be one corrupt NHS employeewhose local privacy officer is less then fully vigilant. Even sealed envelopes will beopen to a corrupt employee prepared to take a small risk of exposure. A worryinglesson comes from banking: until the mid-1980s, getting copies of a target’s bankstatements was hard, as it meant subverting a local bank employee; since then,
the banks have enabled any teller to look up any customer’s account details, andthe street price of bank statements has plummeted.
The consequences for the treatment of drug and alcohol abusers remain to
be seen, but can probably be guessed. There is much evidence that people aremore likely to seek help if confidential services are available; patients want notjust to discuss their problems, but to retain some control.
Victims of child abuse are reluctant to contact the child protection services,
and are more likely to contact Childline  ; and the law used to affordspecial protection to records of sexually transmitted diseases. It seems likelythat, in the case of illegal drug abuse, patients will be loth to divulge offences ifthese are likely to come to the attention of the police.
Although I am aware of no research on confidentiality in the specific context
of substance abuse, its erosion in England will surely fill that gap that in time.
The NHS Care Records Service is a large-scale experiment, but one from whichit will be difficult to go back; if trust is lost, it could take a generation to winback.
