    This article has been cited by other articles in PMC. Abstract Can less information be more helpful when it comes to making medical decisions? Contrary to the common intuition that more information is always better, the use of heuristics can help both physicians and patients to make sound decisions. Heuristics are simple decision strategies that ignore part of the available information, basing decisions on only a few relevant predictors. We discuss: i how doctors and patients use heuristics; and ii when heuristics outperform information-greedy methods, such as regressions in medical diagnosis. Furthermore, we outline those features of heuristics that make them useful in health care settings. These features include their surprising accuracy, transparency, and wide accessibility, as well as the low costs and little time required to employ them. We close by explaining one of the statistical reasons why heuristics are accurate, and by pointing to psychiatry as one area for future research on heuristics in health care. Introduction Accompanied by his anxious wife, a middle-aged male patient arrives at a rural Michigan hospital. He suffers from serious chest pain. The physician in charge, a compassionate-looking woman, suspects acute ischemic heart disease, but is not entirely sure.

    Canada has established a research chair that focusses on practical methods for promoting and implementing shared decision-making across the healthcare continuum. This review found that educational meetings, giving healthcare professionals feedback and learning materials, and using patient decision aids are some techniques that have been tried and might be helpful. However, the review could not determine which of these were best.

    The Art and Science of Clinical Decision Making

    Some attempts are being made to empower and educate patients to expect it. Government and university training programs[ edit ] Canada, Germany and the U. One such program, designed for primary care physicians in Quebec, Canada, showed that shared decision-making can reduce use of antibiotics for acute respiratory problems ear aches, sinusitis, bronchitis, etc.

    An ongoing inventory of existing programs [65] shows that they vary widely in what they deliver and are rarely evaluated. Harvey Fineberg, Head of the US Institute of Medicine , has suggested that shared decision-making should be shaped by the particular needs and preferences of the patient, which may be to call on a physician to assume full responsibility for decisions or, at the other extreme, to be supported and guided by the physician to make completely autonomous decisions.

    In , the programme entered an exciting new phase and, through three workstreams, is aiming to embed the practice of shared decision-making among patients and those who support them, and among health professionals and their educators. One such tool that has been validated, SURE, is a quick questionnaire for finding out in busy clinics which patients are not comfortable about the treatment decision decisional conflict.

    Often more than one healthcare professional is involved in a decision, such as professional teams involved in caring for an elderly person who may have several health problems at once. Some researchers, for example, are focussing on how interprofessional teams might practise shared decision-making among themselves and with their patients. Decisions that ignore them may not be based on realistic options or may not be followed through.

    Patient empowerment requires patients to take responsibility for aspects of care such as respectful communications with their doctors and other providers, patient safety, evidence gathering, smart consumerism, shared decision-making , and more. They take action to improve the quality of their life and have the necessary knowledge, skills, attitudes and self-awareness to adjust their behavior and to work in partnership with others where necessary, to achieve optimal well-being.

    For example, a law enacted in France on 2 March aimed for a "health democracy" in which patients' rights and responsibilities were revisited, and it gave patients an opportunity to take control of their health.

    Similar laws have been passed in countries such as Croatia , Hungary , and the Catalonia. Our patients are experts as well.

    They have knowledge of their prior illnesses, social circumstances, habits and behaviors, risk tolerance, values and preferences. The process of sharing these two bodies of knowledge has several names, including patient-centered care and informed decision making.

    I like this definition: Of course, not all patients are interested in this level of involvement, and some aren't able to participate actively. However, we might be surprised by the number of patients willing to engage with physicians in this way.

    The bottom line is that there is no one correct way to approach clinical decision making. Used in combination, the strategies reviewed in this article form a modified scientific method that you may find helpful, either to implement or to compare with your own process. I have found that this approach works well: Determine your probabilities. In other words, what is the likelihood that your patient has a specific diagnosis, based on his or her symptoms, history, etc.? Gather data by further evaluating the patient — additional history, vital signs and physical exam.

    Update your probabilities, including the pre-test probability of any test you may want to order. Then, carefully collect and interpret additional data from diagnostic tests.

    Consider an intervention to see whether it crosses your treatment threshold. If it does, consider the patient's context before moving forward.

    If you don't have enough information to convince yourself to cross the threshold, consider other options, which may include gathering additional data or watchful waiting. Here's a clinical example: It is January and you are working in a busy clinic in New England. Your patient is a year-old man who is well known to you.

    He presents with acute onset of fever, chills and cough. He also complains of marked fatigue. With just this information, you can begin to determine some probabilities — influenza, viral URI and community-acquired pneumonia.

    Additional data gathering reveals that symptoms have been present for about 24 hours and he has had some ill co-workers. He is otherwise healthy except for hypertension, which has been well controlled on hydrochlorothiazide. His physical exam is non-focal — lungs are clear with good air movement and oropharyngeal mucus membranes are slightly erythematous.

    Epidemiologic data are also important in this case. There has been a recent spike in the number of confirmed influenza cases in your area. Your patient did not get a flu shot this year. With this you update your probabilities, and influenza emerges at the top of your differential diagnosis list.

    The pre-test probability for an influenza swab is relatively high, so the test would have good utility in establishing a true diagnosis. On the other hand, the pre-test probability for a chest X-ray is quite low in this patient with a cough, no respiratory findings and normal pulse oximetry, limiting the usefulness of X-ray as a diagnostic tool.

    It is now time to consider an intervention applied in the context of your patient's life. You know that your patient is on the maintenance crew at a local college and that he has comprehensive private health insurance through his employer.

    You also know that he is a single father of three children and that his illness could be a serious hardship to his family. Given that symptoms have been present for only 24 hours, this patient may be a good candidate for oseltamivir. You give him a prescription and tell him you will call with the results of his influenza swab later in the day to let him know if he should fill the prescription and start the medication. As the previous example helps illustrate, clinical decision making is a balancing act — of art and science, intuition and analysis, gut instinct and evidence, experience and knowledge.

    Decision Making in Medicine - An Algorithmic Approach

    Formalizing our own personal approaches to the process will help us to make clinical decisions with greater confidence. Sometimes, as physicians, we may still feel like we are in the dark, but we must remember that this is the nature of medicine. A reasoned decision-making approach will help light the way to diagnosis and treatment.
