A clinician uses an EHR with CDS to prescribe . The CDSS queries the EHR and discovers that the patient is . The CDSS determines that the proposed drug has as an ingredient. As warfarin in contraindicated during pregnancy, the system triggers an alert to be displayed to the clinician. Relevant clinical guidelines are also displayed to the user. These guidelines suggest a safe alternate, such as , which the clinician then safely prescribes to the patient.

Diagnosis

(e.g. Diabetes)

A clinician uses an EHR with CDS in a case analysis scenario to aid in diagnosis. The clinician records the patient’s age and gender, then prepares to enter specific clinical findings, history, symptoms, etc. As the physician records symptoms of , , and , a ranked list of common diseases, associated with these clinical findings, is dynamically presented to the clinician. At the top of this list is . A scale is used to indicate the level of support for each disease. The CDSS then prompts the clinician for additional findings to help differentiate between diseases. Once a confirmed diagnosis is made, the differential diagnoses can be marked as , , or . An additional finding of is recorded and the level of support for each disease in the list is adjusted accordingly. Support for has now increased from minimal evidence to sufficient evidence. The clinician then selects which opens an evidence screen displaying the recorded findings which either strongly support, support, or do not support the chosen disease. The clinician is then presented with a link that displays all the PubMed articles associated with.

Laboratory

(e.g. Critical Results)

A patient presented at Emergency complaining of and was subsequently admitted to the hospital. The attending physician ordered a series of lab tests including a . Laboratory tests are completed and published to the laboratory information system (LIS). The CDSS then queries the LIS and learns that the is and considered critical. The CDSS then queries the EHR to confirm the patient has been prescribed , which has as an active ingredient. A knowledge base rule has been defined which stipulates, if the drug prescribed contains and the laboratory test indicates a, then inform the user. An alert, in the form of an urgent pager message, is generated and sent to the attending physician. 

An ordering physician has requested an upper , which uses materials. The patient presents at the imaging clinic on the day of their exam. During study protocoling, the imaging department uses the CDSS to query the patient record and determine the patient has a . An alert is triggered to advise the imaging technician about the risk of an allergic reaction. The imaging department, in consultation with the GI radiologist, calls the ordering doctor to discuss the associated risks. Additional guidelines related to preparing for reactions and symptom management ( , , , etc.) are provided via the CDSS. An additional medication is administered prior to the contrast material to reduce the risk of an allergic reaction. The imaging department proceeds with the planned procedure.

A clinician records notes into the appropriate fields of an EHR. For example, Clinical notes: “Pt is 75 yo. LBP (lower back pain) for the past 2 weeks. On exam normal SLR (straight leg raise)…”  Using NLP, these notes are encoded as part of the record storage process. (For example, asand.) The clinician orders a series of imaging tests. The CDSS, based on specific quality metrics (e.g., appropriate use criteria or AUC), evaluates whether or not imaging guidelines are being followed by analyzing the patient's health record together with the proposed tests. If the guidelines were not followed, the CDSS will display an alert informing the clinician that they may want to consider alternative imaging or additional tests. For example, an alert may indicate: “The patient has and . A for this case has an appropriateness rating of 8 (scale of 10) and is recommended.”

A patient has presented at the Emergency Room (ER) complaining of. The attending physician records the appropriate clinical finding codes in the EHR. She then prepares a condition-specific order set in a Computerized Physician Order Entry (CPOE) system. The selection of the order set triggers the presentation of new clinical guidelines based on an analysis of the patient record with the proposed treatment. The physician then choses alternative treatment. Suggested dosage guidance is provided by relevant contextual links within the order set.

A primary care physician logs on to their EHR with CDS and opens a patient chart to record a condition deemed communicable, such as or . The CDSS then triggers an alert to advise the provider that this condition is considered reportable to the jurisdictional public health office. The CDSS then provides a pre-populated smart form which facilitates quick, consistent, and accurate reporting of the condition to the local officer of medical health. The smart form is completed and submitted to the jurisdictional health office. The clinical findings in the report are terminology-encoded which promotes interoperability and facilitates population based health reporting.

A department head uses an EHR with CDS to conduct a treatment analysis. She uses the system to generate a list of all inpatients with a confirmed diagnosis of . She then uses the system to determine which of these patients have received for at least 72 hours. The patients which have not met this criteria are flagged for appropriate treatment.

Staff in an Emergency Department (ED) use their EHR with CDS and clinical management pathways to provide a standardized evidence-based approach to patient assessment of in adults

. The guidelines help document indications and contraindications to determine eligibility. A triage nurse queries the EHR and learns that the patient is over 16 years of age, has a , and one or more episode of which necessitated . The CDSS then triggers an alert to follow the pathway’s medical directives, which are carried out by a Respiratory Therapist (RT). The directives, in this case of , include , establishing various baseline , and administration of a and . The RT then notifies the attending physician who fills out and signs discharge instructions which a nurse then reviews with the patient. The desired clinical outcomes of this pathway include improved adherence to evidence-based management and improved patient outcomes such as reduced number of hospitalizations and lower ED return rates.

Nursing Interventions

Research has provided evidence to show that patients receiving are at high risk for

233604007 |Pneumonia|: 42752001 |due to| = 68052005 |Aspiration|

.

Published guidelines recommend from 30° to 45°, if not contraindicated, to reduce risk of . A nursing supervisor uses a dashboard-like tool in an ICU to monitor patients in her ward. Patients who meet the criteria for risk of are automatically flagged in the system using CDS logic so that the appropriate action may be initiated by nursing staff in the ward. Once the angle of the patient's bed is adjusted, the system is dynamically updated and the flag is removed.
