Textbooks, journal articles, clinical guidelines, image libraries, and material designed for patient education are increasingly becoming available electronically.

Discussing individual electronic health records and relevant reference material with patients is preferable to discussing general information about their problem. If Ms Patel and her surgeon are discussing whether she may need a lumpectomy or a simple mastectomy, then the ability to view a relevant image and brief text making the comparison will probably be more effective than a comprehensive treatise on all the possible procedures.

Dr McKay also says that Ms Smith should be referred to a renal physician, Dr Jones, and a community dietitian for further assessment. Ms Smith agrees, and Dr McKay telephones the hospital to discuss these matters during the consultation.

Dr McKay then uses an electronic referral form on the hospital outpatient booking website to provide the information required by colleagues at the local hospital. In some contexts, this final task can be done using an electronic booking programme.

Clinical management system support information Arranging follow-up support design systems At the end of a hospital outpatient visit a decision is made about whether hospital, a GP, or shared care is most appropriate for the patient. In reality, neither are doing so. To avoid such errors, healthcare systems have developed ways of integrating multiple service providers Functional and clinical outcomes and proactive measures see chronic care model opposite. Overview of the chronic care model. Adapted from Wagner EH.

Effective Clin Pract ;1: Often, patients are If follow-up at hospital is needed then asked to book their next appointment as they leave the clinic. GP follow-up If the hospital team decide that the patient requires medical supervision, but no other hospital resources, the primary care team may be asked to resume sole responsibility for care.

This is the simplest option for hospitals because it only needs a discharge letter to be sent. Most practices in the United Kingdom and other industrialised countries have the technology and systems to support a call-recall system for screening.

Although this can be extended to support GP follow-up of chronic diseases, few practices are able to harness such systems to long term clinical care.

This will probably change in countries like the United Kingdom, where achieving targets is increasingly important. Shared care Although shared care seems the most complex of the three follow-up options, done properly, it may be the best for the patient. An integrated service takes responsibility for all patients with the problem it is set up to deal with.

Specialists ensure that healthcare services are configured to respond effectively to Sharing information across health systems.

Clinical data for example, data patients with problems, and to support clinicians working in the on prescribing or blood pressure in one part of the health system that have community. Good, but often asynchronous, communication between colleagues with complementary skills is vital.

In some systems, records may be seen by clinicians irrespective of where they are working. No matter consultation, written material about their problem, or what arrangement is made for follow-up by the health website addresses that provide further information. Data, often from patient records, are then collected to confirm whether standards are being met, or if there are any defects to treasure. Failure to hit the target for example, to offer annual blood pressure and renal function tests to Ms Smith , is an opportunity to improve the service.

Linking individual electronic patient records from Administration: Am J Manag Care ; Therefore, a practice risks fossilising after doctors finish professional training. Many continuing medical education or continuing professional development activities help doctors carry on learning and improving their skills. These activities include courses, conferences, mailed educational materials, weekly grand rounds, journal clubs, and using internet sites.

In Patrick Murphy is a 6 year old boy who has recently many countries, evidence of this process is needed for doctors returned home from a hospital admission. The discharge to continue to practice. Although these activities may increase letter asks you to prescribe inhaled steroids and a phosphodiesterase 4 inhibitor knowledge, their impact on clinical practice is variable The aim of traditional medical education is to commit knowledge to memory and then use this knowledge in the workplace.

The way knowledge is learnt influences its recall and application to work.

One tactic to improve the process is to Workplace learning means finding solutions to clinical ensure that learning happens in the clinical workplace. Lessons problems when they arise, or soon after, with minimum are learnt faster and recalled more reliably when they originate effort.

When unsure about what has happened, why, or in everyday experience. Workplace learning is hard to achieve. It emphasises problem solving and learning skills—such as how to find relevant answers fast—not learning facts.

Barriers and solutions Nobody can find a satisfactory answer to every clinical question or information need, especially as there are about two needs for every three clinical encounters.

Many important clinical questions have no satisfactory answer—for example, what is the cause of motor neurone disease? Other questions are simply interesting rather than information needs.

A range of practical difficulties face doctors who follow the approach of learning in the workplace. Some suggestions about how to overcome the difficulties follow.

In the United Kingdom, the National electronic Library for Health aims to Too many questions, not enough time provide answers within 15 seconds that take only 15 seconds to read Doctors generate approximately 45 questions about patient care every week, and they probably allow two minutes to answer each one.

Time is always short. They often have to adjust the threshold for seeking answers, Prioritisation of clinical questions prioritising questions that have the highest clinical impact and 1 Answers needed now are quickest to answer.


When doctors have time, they can pursue all answers. If they never pursue other answers, they will miss many clinical advances. It is often hard to recognise when knowledge is lacking, and so it is important to sometimes pursue answers even when only slightly uncertain of the answer. They could also increase the time available for workplace learning.

Individually, doctors can work for longer Patient ID: Lack of clear questions Main Reference: Asking clear questions is not easy. Sometimes doctors feel uncertain and fail to formalise a question, which makes it Adapted from a page from the harder to find the answer.

When working alone, some clinicians Clinical bottom line: This source should provide answers that are clinically relevant, scientifically sound, and in a form that can influence decisions. One solution is a library in the workplace that contains current text and reference books, relevant reprints, and electronic resources. The library must be close and organised for rapid access.

The material should be filtered for clinical relevance and be evidence based, such as Clinical Evidence in book or CD-Rom format or an indexed collection of systematic reviews. These sources will not answer all questions. Ideally, doctors will then retrieve the full text of relevant articles because relying on the abstract alone can be misleading. Clinical evidence is a useful resource in workplace learning Thus, tempting though it may be to rely on abstracts alone—especially because they are now so accessible through PubMed—it can be dangerous.

For years, NHS poisons and drug information services have provided similar services that give instant answers to specialist questions. Some libraries, primary care trusts and academic departments have services that cover many topics. The service usually returns a telephone call or sends a summary within two to four hours. Despite their obvious potential, these services seem underused at present.

Parochialism If doctors only look up answers to questions arising in their own practice, their knowledge will depend on the local case mix. Most doctors broaden their knowledge by reading a general medical journal or looking up points raised in replies to referrals, inpatient summaries, clinic letters, or laboratory reports.

Some participate in multidisciplinary clinics or ward rounds, or join colleagues in an email discussion group. To be A PubMed search filters for clinical queries ready for rare, serious problems that need an instant response, some clinicians use patient simulators to practice managing cardiopulmonary arrest, anaesthetic accidents, or brittle diabetes.

Lack of incentives To maintain the enthusiasm to keep looking up answers to clinical questions, doctors can keep a log book of questions and answers, or conduct clinical audits that compare practice and outcomes with results a year ago. Sharing insights is an incentive to learn, and giving a presentation often prompts discussion, especially if it is short, and it defines and deals with a real clinical problem along with sources searched, the answers found, and actions taken.

A huge volume of data flows across the desk of a director of You are a director of public health. The local paediatric public health see box opposite. An individual prescriber, or group, may have an erroneous belief or inadequate training. Critical incidents or other signals often indicate that more data such as data on prescribing steroids for paediatric asthma in primary care and outpatients are needed. Sources of data Health services are awash with data.

Earlier articles in the series described the large and increasing numbers of sources of data available to consumers, patients, clinicians, and administrators. Clinicians, teams, divisions, and other groups collect the data they need to carry out their work, and they may do so using coding and terms that others can understand and share.

One difficulty with secondary uses of clinical data is that, having obtained the data indicating a problem exists, the issue must be dealt with effectively. It may be that the individual or group who identify the problem have the knowledge, skills, and resources to resolve it. In other cases, such as these potentially avoidable asthma admissions, those responsible are not those who have uncovered the issue, and those potentially responsible may be unaware of the problem.

Clinical governance and the drive for quality improvement in the new NHS in England. This poses another difficulty with the secondary use of clinical data.

Studies have shown that interpretation of data is influenced by the method used to summarise the results. Once the decision has been taken to act on data, how best to present the information should be considered.

Crossing the quality chasm: The interventions chosen should be tailored to the underlying Washington, DC: National Academy Press, problem.

The community health index number CHNo is a unique 10 digit number that includes the date of birth of individuals born, or moving to, Scotland so Record linkage that their encounters with the health service can be linked Deterministic or probabilistic methods can be used with similar success rates to link records.

In the former case, a unique patient identifier, such as a 10 digit community health index Genera number, is applied to all personal health data—for example, Laboratory practiti l data oner Dental laboratory test requests and prescriptions. In the latter case, algorithms determine the likelihood that two items of data belong to the same person.

The Soundex system converts a name to a code for example, Michael becomes M The first letter is the first letter of the word, and the numbers represent phonetic parts of latter syllables.

The algorithm determines that Hospital John Smyth and John Smythe is the same child with asthma if Pharmacy sufficient other characteristics date of birth, street name on the CHNo admission data and community prescriptions match.

Record is that clinicians often rely on their fallible memories. Sometimes work related contact numbers are stored notes, or video in diaries or mobile phones, and either could be lost or stolen.

External agencies often manage directory information better than the NHS. Private healthcare organisations also manage information better than the NHS because they realise that there is a business need and that benefits will accrue if their clients have easy access to information on how to use their services.

Assembling, maintaining, and accessing directory information One of the reasons that any clinician could face a situation like the one described in the scenario is because the people and organisations in healthcare services change fast. In the future they will change even faster, making directory information NHS HealthSpace website allows patients to store information and will allow more important, but more difficult to assemble.
