Introduction: Nurses who provide inpatient care to acute ischemic stroke (AIS) patients routinely perform neurologic assessments that are intended to monitor the stability of neurological deficit. A variety of assessment tools are used, however none of these tools have been validated as a stroke specific assessment tool for nurses. The purpose of this study was to evaluate the validity of a novel nurse performed stroke assessment tool, the Post Stroke Assessment Tool (PSAT). Methods: An interdisciplinary team, from a single certified primary stroke center devised the PSAT. The PSAT encompasses evaluation of 4 components of neurologic function (level of consciousness, cranial nerves, limb strength, and limb coordination). PSAT scores range from 0 (no deficits) to 63. A Clinical Nurse Educator trained neurology nurses on PSAT performance prior to study initiation. A nurse performed the PSAT on patients with AIS. A physician performed the National Institutes of Health Stroke Scale (NIHSS) within 30 minutes of PSAT completion. General linear regression and Pearson correlation was used to evaluate the relationship between scores. All analysis was done in SAS® Version 9.3 for Windows. Results: A total of 26 nurses conducted a PSAT on 46 patients. Mean NIHSS was 6.1 (S.D. +/- 6.9) and mean PSAT score was 10.2 (S.D. +/- 11.8). The r 2 was 0.8349. Overall, the model was significant (p-value < 0.0001). Both the regression model and Pearson correlation showed a significant relationship between PSAT and NIHSS (p <0.0001 for both). Spearman correlations showed a significant relationship between PSAT and NIHSS within each category (p < 0.003 for each category). Conclusions: In this exploratory study, the PSAT appears to be a reliable nursing assessment tool to monitor post stroke neurologic deficit. Total and categorical PSAT scores highly correlated with total and categorical NIHSS scores. No attempt to compare inter-rater reliability from one nurse to another was included in this study. Future research concerning the reliability of the PSAT will be necessary before this tool can become a standard nursing assessment for patients following AIS.
Background and Purpose: The Joint Commission mandates that certified Primary Stroke Centers provide patient education addressing stroke warning signs, use of 911 for access to emergent care, personal risk factors, medications prescribed, and follow-up after discharge. The patient’s retention of this information is imperative for reducing secondary stroke occurrence and morbidity. This study evaluated the Acute Ischemic Stroke (AIS) patient’s ability to retain the stroke education information provided near the time of hospital discharge. Methods: A prospective hospital-based cohort study was comprised of AIS patients who were admitted to the stroke unit at an urban core hospital located in Jacksonville, Florida. Diagnosis of AIS was confirmed by a Neurologist and by a CT or MRI. All participants received Joint Commission mandated stroke education administered by a nurse during their hospitalization. The patient education included verbal instructions with the use of illustrative handouts. Stroke education retention was evaluated near the time of hospital discharge using a five-question survey. The level of health literacy was assessed by the Short Version-Test of Functional Health Literacy in Adults (S-TOFLHA). Results: Of 189 consecutive patients screened between October 2009 and June 2010, 100 (53%) consented to participate. Seventy patients were excluded due to severe cognitive impairment, and 18 eligible patients refused to participate. The average age was 60 years old, 57% were male, 56% African American, 43% resided within the urban core, and 75% earned less than $25,000 per year. A total of 59% of patients had low to marginal health literacy. Retention of stroke knowledge was lacking even with standard stroke post education; 12% could name all 5 warning signs, 43% knew their personal risk factors, 85% knew to call 911 for warning signs of stroke, 76% knew their medications prescribed for stroke prevention, and 53% knew their type of stroke. Conclusion: Current methods of educating hospitalized AIS patients may not adequately prepare the hospitalized stroke survivor with basic knowledge on stroke prevention. Alternative methods of education will need to be developed for AIS patients in urban core hospitals. By using the Patient-Centered Care model and principles of adult learning, this study has the potential to lead to changes in educational interventions, nursing practices, and communication.
