    Introduction

    The amount of biomedical knowledge doubles every 20 years, and new classes of drug (such as phosphodiesterase 4 inhibitors) become available when lectures at medical school are over. 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 many countries, evidence of this process is needed for doctors to continue to practice. Although these activities may increase 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 ensure that learning happens in the clinical workplace. Lessons are learnt faster and recalled more reliably when they originate in everyday experience.

    Learning in the workplace means spending a minute here or three minutes there to find answers prompted by the clinical questions and learning opportunities that come up in every working day, rather than doing continuing medical education for an intensive two hours a week, or a few days a year. 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.

    Too many questions, not enough time

    Doctors generate approximately 45 questions about patient care every week, and they probably allow two minutes to answer each one. This adds up to an extra hour and a half per week, and even though it represents only 3% of their working time, where do doctors find this time? Time is always short. They often have to adjust the threshold for seeking answers, prioritising questions that have the highest clinical impact and are quickest to answer.

    In the United Kingdom, the National electronic Library for Health aims to provide answers within 15 seconds that take only 15 seconds to read

    Prioritising clinical questions by the likely impact of the answer means distinguishing between the questions in the box opposite. When doctors have time, they can pursue all answers. When under pressure, they pursue answers that are needed now (category 1). 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.

    Prioritisation of clinical questions

    Workplace learning means finding solutions to clinical problems when they arise, or soon after, with minimum effort. When unsure about what has happened, why, or what to do, answers should be looked up

    To ease time pressure, clinicians can spend less time answering a question by using knowledge resources that are comprehensive, and can be instantly accessed and easily searched. They could also increase the time available for workplace learning. Individually, doctors can work for longer hours, reserving time for "reflective practice" with a preceptor or mentor, exploiting "teachable moments," perhaps by answering an educational prescription. Overall, the medical profession needs to recognise the sanctity of workplace learning throughout doctors' careers: life long, self directed learning.

    Turning clinical problems into easily investigated formats

    Lack of clear questions

    Asking clear questions is not easy. Sometimes doctors feel uncertain and fail to formalise a question, which makes it harder to find the answer. Immediate identification of clinical questions is important, and is easiest to do on ward rounds or when teaching students. When working alone, some clinicians log their questions (for example, on BMJLearning), then look up the learning resources on the website (the "just in time learning" package on childhood asthma) or other sources, or they discuss the answer with peers later. Structuring clinical questions using the problem, intervention, comparison and outcome (PICO) model makes them easier to focus, recall, and answer.

    Lack of answers

    A source of answers needs to be available in the workplace. 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.

    Clinical evidence is a useful resource in workplace learning

    These sources will not answer all questions. In Patrick Murphy's case (see scenario on p 1129) the treatment is not indexed, and so online access to Medline will be needed, preferably via the PubMed clinical queries search page that provides answers useful to practicing doctors. Ideally, doctors will then retrieve the full text of relevant articles because relying on the alone can be misleading. When Pitkin compared the statements made in 264 structured s in six medical journals with the corresponding article, a fifth contained statements that were not substantiated in the article and 28% contained statements that disagreed with those in the article. Thus, tempting though it may be to rely on s alone—especially because they are now so accessible through PubMed—it can be dangerous.

    An alternative to carrying out the search yourself is to call or email a question answering service, such as ATTRACT, for clinicians working in Wales. 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 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. Although time spent on simulators does not yet count towards doctors' continuing education, taking part in interactive cases in some journals does.

    The CATmaker tool is used to create critically appraised topics

    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. Such log books and audit reports will become part of doctors' folders for accreditation and annual appraisal.

    Cultural changes associated with workplace learning

    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). This activity can be formalised as a single page, dated, critically appraised topic (CAT), and stored in a loose leaf folder or a practice intranet for others.

    Lowering barriers is also motivating: an old BNF in a desk drawer will be used more often than a current version in the practice library 10 m away, or one in the health library 5 km away. Electronic libraries and the internet bring the world's literature to your desktop, but can take longer and yield fewer answers to clinical questions than paper sources. This is changing. A German study found that clinical use of online learning was about ten times that of print journals.

    Summary

    Barriers to workplace learning can be overcome, but a minor culture change in the medical profession is needed. This shift is already taking place in undergraduate medical education and in primary care. Clinical governance, risk management, patient empowerment, and the National Programme for IT will further advance the change.

    Using clinical questions to guide workplace learning relies on the motivation of individuals, teams, and organisations. It goes hand in hand with an open attitude to clinical errors and near misses. Motivation is especially necessary to fund the instant access resources needed to provide knowledge during clinical work. Fortunately, electronic media provide a simpler, cheaper method for workplace learning than paper libraries, although there is evidence that health librarians on site are still needed to support better clinical use of these resources.(Jeremy C Wyatt, professor of health info)
