Effectiveness of care in acute dizziness presentations

Area of Science:

• Neurology
• Healthcare Management
• Clinical Effectiveness

Background:

• Dizziness is a common presenting complaint in emergency departments.
• Effective management of dizziness is crucial for patient outcomes and healthcare resource utilization.

Purpose of the Study:

• To evaluate the impact of a newly implemented management algorithm on the effectiveness of care for patients presenting with acute dizziness.
• To assess changes in diagnostic practices, treatment outcomes, and health economic effects following algorithm implementation.

Main Methods:

• An interventional study design comparing data from medical records before and after algorithm implementation.
• Data collected for two periods: Period 1 (2012-2014) and Period 2 (2016-2017).
• Analysis of effectiveness markers including diagnostic testing, diagnosis rates, hospitalization, and neuroradiological investigations, alongside cost analysis.

Main Results:

• Significant increase in Dix-Hallpike testing (20.8% to 37.7%) and Benign Paroxysmal Positional Vertigo (BPPV) diagnoses (7.6% to 15.3%).
• Reduction in hospitalizations (61.5% to 47.6%) and overall neuroradiological investigations (44.8% to 36.3%).
• Average cost per patient decreased from $2561 to $1808, with a shift from CT to MRI for cerebrovascular investigations.

Conclusions:

• The management algorithm was associated with improved effectiveness of care for dizzy patients.
• The algorithm facilitated more targeted diagnostic approaches and reduced unnecessary healthcare utilization.
• Implementation resulted in significant cost savings while maintaining diagnostic sensitivity for cerebrovascular causes.
