Patient Experiences of Posterior Circulation Stroke at Symptom Onset A Qualitative Study
Main Article Content
Abstract
Introduction: Posterior Circulation Stroke (PCS) accounts for around 20% of ischaemic strokes but is missed more frequently than Anterior Circulation Stroke (ACS), mainly due to its subtle symptoms and non-specific presentation. Currently there are no studies evaluating PCS patients’ experiences of their symptoms at stroke onset, and so this study aimed to evaluate this to aid in paramedic understanding and detection of PCS.
Methods: A qualitative descriptive approach was adopted. Clinical Nurse Specialists and Advanced Nurse Practitioners in Stroke purposefully sampled PCS patients confirmed by MRI and admitted to the stroke wards of University Hospital Galway and Mayo University Hospital in the West of Ireland. Once consented, semi-structured interviews were carried out, transcribed verbatim, and thematic analysis completed. Inclusion criteria were any stroke in the posterior portion of the brain confirmed by MRI, patient ≥18 and less than four weeks since stroke onset.
Results: Ten patients were interviewed. 90% did not believe they were having a stroke. Only 50% sought help immediately. 70% were taken to hospital by ambulance and 30% were taken by car. 20 different symptoms were reported by participants. Loss of balance was the most prevalent symptom, followed by being unable to walk unaided, dizziness, vision disturbance and headache. 60% had prodromal symptoms prior the onset of their stroke. Qualitative analysis created three main themes: 1) Physical Disturbance, 2) Visual and Spatial Disturbance and 3) Dismissal.
Conclusion: PCS is a difficult condition for patients to recognize, which affects their help seeking behaviour, delays treatment and negatively affects outcomes. These patients described a wide variety of symptoms and their reasons for dismissing them. These results may help inform future paramedic educational programs for PCS awareness and recognition in the prehospital environment.
