Extract of sample "Stroke: Evidence-Based Practice"

Evidence Based Practice Stroke is a leading cause of death and adult disability all around the world. Recovery from stroke increases the mortality of the patient but depression highly decreases the rate of morbidity of the strokes patient. Several studies have focused on the impact of stroke on the social recognition and quality of life of the patients. Therefore, it can be said that cognitive behavioral therapy may play a major role in decreasing the rate of prevalence of PSD focusing on the cognitive and psychological treatment of patients. Therefore, the study is aimed to focus on cognitive behavioral therapy for PSD patients as compared with the pharmacological therapy. Research revealed that the effectiveness of pharmacological therapy in treating PSD patients in evident. However, augmented and tailored cognitive behavior therapy can play a vital role in improving treatment outcomes of PSD patients Evidence Based Practice Problem Post Stroke Depression increases the risk of mortality and morbidity. Recovery from stroke decreases the rate of mortality of the patients but depression highly increases the rate of morbidity of the strokes patient. It also impairs the functional capacity of the patients and hinder with the social cognition attitude of the patients with stroke. The PICOT question to address the problem is: In stroke, survivors (P) does Cognitive Behavioral Therapy (I) as compared to anti-depressants (C) will increase the treatment outcomes of Post-Stroke Disorder (O) after treatment of stroke (T)? Significance Stroke is a leading cause of death and adult disability in the UK. Around 1,30,000 people met the stroke every year. The National Health Service has given an estimate of around £2.8 billion expenditure by hospitals and around £2.4 billion cost spent on informal care by the caregivers to the PSD patients (Broomfield, Laidlaw, Hickabottom, Murray, & Gillespie, 2011). Several studies have focused on the impact of stroke on the social recognition and quality of life of the patients. Therefore, it can be said that cognitive behavioral therapy may play a major role in decreasing the rate of prevalence of PSD focusing on the cognitive and psychological treatment of patients. Background The psychological impairment also appears in the patients of Post-Stroke Depression showing the signs of depression, anxiety, sadness, loneliness, isolation, alienation, etc. The cost and expenditure served on the treatment of PSD patients is also very high. Mostly the geriatrics and adults have been found as the victim of PSD however in some studies young adults also report the symptoms of PSD. Therefore, the study is aimed to focus on cognitive behavioral therapy for PSD patients as compared with the pharmacological therapy. Gaps While searching for the literature to address the PICOT question, it was found that few researches have been conducted on the evaluation of cognitive behaviors therapy for Post-Stroke Depression. Most of the research was found on the pharmacological treatment of PSD. Secondly, no study was found in which comparative analysis of cognitive-behavioral therapy with psychotropic medicinal treatment was conducted.
