Background
In older adults hospitalized with heart failure (HF), cognitive impairment is associated with increased hospital readmission and mortality risk. There is no consensus on an objective, scalable method of cognitive screening in this population.
Objective
The aim of this project was to determine the feasibility, test-retest reliability, and convergent validity of the Processing Speed Test (PST), a test of information processing, attention, and working memory administered on an iPad in older adults hospitalized with HF.
Methods
Patients hospitalized with HF (n = 30) and age-, sex-, and education-matched controls (n = 30) participated in the study. To determine test-retest reliability, the PST was administered on an iPad on 2 occasions, separated by 12 to 48 hours. The Symbol Digit Modalities Test was administered at the first testing time point to determine convergent validity.
Results
Test-retest reliability of the PST was 0.80 and 0.92 in individuals with HF and controls, respectively. Convergent validity was 0.72 and 0.90 for individuals with HF and controls, respectively. Time to complete the PST was similar for both individuals with HF and controls (<5 minutes).
Conclusion
The iPad-based deployment of the PST was a feasible, reliable, and valid cognitive screen for older adults hospitalized with HF. Using a tablet-based self-administered cognitive screen in older adults with HF provides a method of cognitive assessment that is amenable to widespread clinical utilization.
The cardiology diagnostic are the methods of identifying current or past heart conditions, which can advise caregivers on patient diagnosis and provide a proper therapy plan, nowadays couple new diagnostic methods have been developed and some of them like radionuclide myocardial perfusion imaging, coronary computed tomography angiogram, cardiac magnetic resonance imaging, intravascular ultrasonography, optical coherence tomography, intravascular thermography, intravascular elastography, and near-infrared spectroscopy have been approved for clinical use. Not only the advanced technologies, the new biomarkers, and genetic markers may provide new potential targets for the diagnosis, therapy, and prevention of heart diseases.
