Medical diagnosing tool

Additionally, these tools can be used by customers at home to keep track of important medical information that may need to be regularly monitored for certain health concerns. The selection of medical diagnostic equipment is as large as it is diverse, and because of this, many customers may feel uncertain as to which diagnostic products may be necessary for their needs. Depending on the setting, patient type, and condition to be monitored, there are many different tools that may be necessary for diagnosis.

To help make the shopping process more simple, this section outline some of the most common medical diagnostic equipment, as well as some important considerations to make when looking for the right products.

Perhaps the most familiar of all medical diagnostic equipment, stethoscopes allow their user to listen to the internal functions of the body—primarily the heart and lungs. This information can be crucial in diagnosing conditions related to either or both of these regions, including pneumonia, arrythmia, and many others.

These devices are able to provide general information about the ear, but can also provide insight about possible infections or other illnesses.

Another familiar tool that is often used in checkups, ophthalmoscopes allow the healthcare professional to examine the interior of the eye. In doing this, they assist in the diagnosis of a variety of different eye conditions. These handy devices do exactly what their name suggests: calculate body fat percentages. They do this through bioelectrical impedance analysis, a pain-free method of measuring an electrical current that passes through the tissues of the body and calculates the resistance experienced during that time.

This can provide important health information for the patient, as well as indicate some potential health concerns. While these medical diagnostic products are only a small selection of a vast category, they are some of the most commonly-used tools in general diagnosis. However, to make the process of purchasing easier, some medical diagnostic equipment is sold in kits that are equipped with multiple useful items. Depending on the kit, any combination of ophthalmoscopes, otoscopes, transilluminators, and other tools may be included.

These kits can be particularly useful for new doctors or medical school students who need an affordable set of reliable diagnostic equipment.

Here are a few important things to consider. Diagnostic products, while having the same general function, may be constructed in a number of different ways. Some products may use plastic regions while others may be strictly metal.

Because of this, it is worth considering the expected wear and tear for your equipment and which construction will be best to meet those demands. Of particular concern in busy clinical settings is the issue of hygiene with medical devices.

Checklists are another approach that has been implemented to improve the safety of care by, for example, preventing health care—acquired infections or errors in surgical care. Checklists have also been proposed to improve the diagnostic process Ely et al. Developing checklists for the diagnostic process may be a significant undertaking; thus far, checklists have been developed for discrete, observable tasks, but the complexity of the diagnostic process, including the associated cognitive tasks, may represent a fundamentally different type of challenge Henriksen and Brady, Inductive reasoning involves probabilistic reasoning see the following section.

Clinical History and Interview Acquiring a clinical history and interviewing a patient provides important information for determining a diagnosis and also establishes a solid foundation for the relationship between a clinician and the patient.

Physical Exam The physical exam is a hands-on observational examination of the patient. Diagnostic Testing Over the past years, diagnostic testing has become a critical feature of standard medical practice Berger, ; European Society of Radiology, Medical Imaging Medical imaging plays a critical role in establishing the diagnoses for innumerable conditions and it is used routinely in nearly every branch of medicine.

Referral and Consultation Clinicians may refer to or consult with other clinicians formally or informally to seek additional expertise about a patient's health problem. Diagnostic Uncertainty One of the complexities in the diagnostic process is the inherent uncertainty in diagnosis. Kassirer concluded that: Absolute certainty in diagnosis is unattainable, no matter how much information we gather, how many observations we make, or how many tests we perform.

Time Of major importance in the diagnostic process is the element of time. Population Trends Population trends, such as the aging of the population, are adding significant complexity to the diagnostic process and require clinicians to consider such complicating factors in diagnosis as comorbidity, polypharmacy and attendant medication side effects, as well as disease and medication interactions IOM, , b.

Diverse Populations and Health Disparities Communicating with diverse populations can also contribute to the complexity of the diagnostic process. Mental Health Mental health diagnoses can be particularly challenging. If the symptoms are highly typical e. The representativeness bias refers to the tendency to make decisions based on a typical case, even when this may lead to an incorrect judgment.

The representativeness bias helps to explain why an incorrect diagnosis e. Base-rate neglect describes the tendency to ignore the prevalence of a disease in determining a diagnosis. For example, a clinician may think the diagnosis is acid reflux because it is a prevalent condition, even though it is actually an MI, which can present with similar symptoms e.

The overconfidence bias reflects the universal tendency to believe that we know more than we do. This bias encourages individuals to diagnose a disease based on incomplete information; too much faith is placed in one's opinion rather than on carefully gathering evidence. This bias is especially likely to develop if clinicians do not have feedback on their diagnostic performance.

Psych-out errors describe the increased susceptibility of people with mental illnesses to clinician biases and heuristics due to their mental health conditions. Patients with mental health issues may have new physical symptoms that are not considered seriously because their clinicians attribute them to their mental health issues. Patients with physical symptoms that mimic mental illnesses hypoxia, delirium, metabolic abnormalities, central nervous infections, and head injuries may also be susceptible to these errors.

Dual Process Theory and Diagnosis This section applies the dual process theory of clinical reasoning to the diagnostic process Croskerry, a , b ; Norman and Eva, ; Pelaccia et al.
