Peripheral Artery Disease III: Interprofessional Care

200
Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Area of Science:

  • Neurology
  • Public Health
  • Healthcare Quality Improvement

Background:

  • Stroke incidence in Canada is projected to rise significantly in the coming decade.
  • Timely hyperacute stroke care, including thrombolysis, is crucial for improving patient outcomes.
  • A tertiary care center implemented a quality improvement initiative to address suboptimal stroke care performance.

Purpose of the Study:

  • To evaluate the impact of a quality improvement initiative on door-to-needle (DTN) times.
  • To determine if reduced DTN times and increased treatment within 60 minutes are associated with improved clinical outcomes in stroke patients.

Main Methods:

  • Retrospective chart review of 324 patients receiving thrombolysis before and after the initiative.
  • Data collection included patient characteristics, process measures, and primary outcomes (mortality, adverse events, discharge location, independence).
  • Statistical analysis used Chi Square and two-tailed t-tests to compare pre- and post-intervention data.

Main Results:

  • Median DTN times and the proportion of patients treated within 60 minutes significantly improved post-intervention (p < 0.001).
  • In-hospital mortality decreased significantly (p = 0.013), and favorable discharge locations increased (p = 0.005).
  • Mortality rates were significantly lower for patients treated within 60 minutes post-intervention (p = 0.044).

Conclusions:

  • The quality improvement initiative successfully reduced DTN times and positively impacted clinical outcomes.
  • This study underscores the necessity of sustained investment in strategies for timely hyperacute stroke care.
  • Optimizing stroke care processes is essential for achieving the best possible patient outcomes.
