Clinical Scorecard: Exploring Ambulatory Care Patterns to Understand Inpatient Diagnostic Risks
At a Glance
Category Detail
Condition Diagnostic Errors
Key Mechanisms Ambulatory care transitions and diagnostic uncertainty
Target Population Patients with multiple outpatient encounters prior to hospitalization
Care Setting Inpatient care
Key Highlights
Patients with two or more ambulatory encounters in 14 days before admission have over twice the odds of harmful diagnostic errors. Traditional markers of complexity did not show a significant association with harmful diagnostic errors. The study emphasizes the importance of communication between outpatient and inpatient clinicians. Provisional diagnostic labels should be used to mitigate diagnostic momentum. Clinical decision support tools could identify patients at risk for diagnostic errors.
Guideline-Based Recommendations
Diagnosis
Consider the context of outpatient encounters when assessing diagnostic risks.
Management
Utilize closed-loop communication between outpatient and inpatient clinicians.
Monitoring & Follow-up
Document uncertain diagnoses as working diagnoses and acknowledge discordant findings.
Risks
Recognize the potential for diagnostic errors during care transitions.
Patient & Prescribing Data
High-risk patients with repeated outpatient visits before admission.
Increased scrutiny and reassessment of diagnoses may be necessary.
Clinical Best Practices
Implement diagnostic time-outs and cross-checks to support diagnostic reasoning. Flag patients with multiple outpatient encounters in EHR for increased diagnostic scrutiny.
