Abstract

Background: Stroke is the second leading cause of death in the world and the leading cause of death in China. Post-stroke depression is prevalent, affecting approximately one third of stroke survivors at any given time. However, the depressive symptoms of stroke patients are often overlooked in clinical practice.

Objective: The aim is to investigate the knowledge, attitudes, and practice status of nurse clinicians on the assessment of post-stroke depressive symptoms and explore the influencing factors, so as to provide empirical evidence for clinical education related to Post-Stroke Depression (PSD) and the development of nursing clinical pathways for screening.

Methods: A self-designed questionnaire is used to survey 298 nurse clinicians in Guangdong Province of China. 12 nurses and nurse managers among the study subjects are purposefully invited to participate in semistructured interviews for in-depth discussion about factors affecting the status of assessment.

Results: The total scores of the survey of clinical nurses assessing poststroke depression are (84.76±13.255). The scores of knowledge, attitude, and practice of the survey are (25.08±8.975), (33.33±5.483), and (26.35±6.719) respectively. The results of multiple linear regression analysis show that predominate influencing factors of knowledge include position and whether appropriate training is offered by the employer. Nurses’ attitudes toward assessment are influenced by where they worke. Influencing factors for the practice of assessing PSD symptoms include nurses’ positions, participation in training, knowledge level, and attitudes.

Conclusion: The total scores of nurse clinicians in assessing the symptoms of PSD are below average. The current practice needs to be improved.

Introduction

Stroke seriously impacts human health and life. A Lancet Sino- US collaborative research project shows that stroke is the second leading cause of death in the world and the leading cause of death in China, where 1/5 of the world’s population resides [1]. The lifetime risk of stroke of Chinese has reached an alarming 39.3%, which is the highest in the world. The epidemiological data released by the Chinese Stroke Society shows that there are 14.94 million stroke patients in China with 3.3 million new cases each year [2]. Post Stroke Depression (PSD) is a common complication among approximately 1/3 of stroke survivors [3]. PSD affects the recovery of patients’ physical function and Activity of Daily Living (ADL) decreasing their quality of life. Severely depressed PSD patients have a high rate of suicide [4]. A number of studies have shown that early identification and interventions of these patients is beneficial for the prognosis related to rehabilitation of neurological function and improvement of quality of life resulting in reduction of disability and mortality rates [5-6]. Canadian Best Practice Recommendations for Stroke Care recommend that all stroke patients should be considered at high risk for depression and be screened [7]. However, in clinical practice, the depressive symptoms of stroke patients are often overlooked, and the diagnosis rate and treatment rate remain low [8]. There is a disconnect between research findings and clinical applications. Nurses, as the direct caregivers for patients during hospitalization, should be sensitive to the emotional changes of their care recipients. Currently, there is a lack of investigations into the knowledge, attitude, and practice in assessing PSD symptoms by registered nurses in China. This study aims to bridge this gap by exploring various influencing factors related to the assessment of PSD symptoms. We hope to provide empirical evidence for nursing education and the development of clinical pathways for PSD screening. Change of clinical practice will facilitate the improvement of diagnosis and treatment outcome of the disease.

Participants and Methods

Participants

Guangdong is a developed coastal province in China ranking first with 10.9% of the nation’s total GDP [9]. The population in the province has relatively good access to the healthcare system. From December 17, 2019 to July 5, 2020, a convenient sampling method was adopted to investigate the PSD screening practice of nurse clinicians working in neurology, neurosurgery, cardiovascular medicine, and rehabilitation from 18 hospitals in 12 cities in Guangdong. This sample is representative of nurses in the developed regions of China.

Inclusion criteria:

• Those who have unrestricted licensure as registered nurses and

• Have worked in the department for at least one year and

• Have consented to participate in the study.

Exclusion criteria:

• Nurses who have not obtained their RN licensure or

• Are not involved in direct patient care or

• Are on leave of absence, residency, clinical rotation, and practical training.

The qualitative portion of the study adopts a phenomenological research method. Among the respondents of the survey, nurse clinicians or nurse managers from neurology and neurosurgery were purposefully selected for the semi-structured interviews. The selection criteria are: Participants must have worked in the department for 5 years or longer and have expertise in stroke care.

The study proposal has received the approval of the ethics committee of Shantou University Medical College. Principles of multivariate analysis call for a sample size 5 to 10 times the number of variables [10]. This research contains 18 variables. Based on the above ratio, the sample size needed would be 216, considering a 20% drop out rate. The study has a final number of 298 respondents (n=298), which meets the requirement.

Methods

This study uses a combination of quantitative and qualitative methods. The quantitative part consists of 2 self-designed questionnaires. The qualitative part employs the approach of semistructured interviews to explore factors affecting the nurses’ practice of PSD assessment.

General demographic of study participants: Data to be collected include gender, educational level, healthcare organization, department, specialty experience, administrative position, technical title, history of participation in training on PSD, and whether the department has a protocol for screening.

Self-designed questionnaire: The survey is compiled after consulting neurologists, nurse specialists, and statisticians. The content of the knowledge dimension is based on the guidelines for post-stroke depression [11] and expert consensus[3]. The knowledgeattitude- practice model is frequently used in the nursing profession, which divides the change of nursing behavior into three continuous processes of acquiring knowledge, generating attitudes and beliefs, and forming nursing practice. Knowledge is the foundation of behavior, and belief is the driving force of behavior [12]. There are 28 items in the survey, 10 of which are in the knowledge dimension. All are multiple-choice questions. Each question has 5 possible points if answered correctly. The higher the score, the better the respondent’s knowledge level of PSD. Attitude and practice dimensions are based on the Likert 5-level scoring method, with 9 items in the attitude and practice dimension respectively. Each item is worth 1 to 5 points with a total possible score of 45 points per dimension. The higher the score, the more positive the nurses’ attitudes towards PSD screening and the more likely the nurse would assess the patient’s PSD symptoms as well. Standard score (percentage of correct answer) = raw score/full score × 100. Scores classification: 80=good; <60=poor; 60-79=average [13]. The Cronbach’s a coefficient of the questionnaire is 0.86. The half-reliability is 0.608. The survey instrument can be found as supplementary material in the appendix.

Interview questions: Interview questions incorporate the investigators’ clinical observation into the framework of the Roy adaptation model with focus on the primary and secondary assessments [14]. The investigators are interested in finding out whether nurses have performed secondary assessment on their patient, that is, whether they would assess the impact of the inherent stimulus, primary stimulus, and secondary stimulus of the patient’s emotional disorder. The interview outline has been revised and improved after consultation with nursing experts in the specialty.

Data collection: Data collection in this study is done via an online portal. With permission of the hospitals’ administration, the link of the questionnaire including uniform instructions is sent to the head nurses of the department who would then distribute it to the staff nurses. Response to the survey is anonymous. All questions must be answered for the survey to be valid. The total time needed to answer all questions is between 10-20 minutes. Data is then extracted and screened strictly according to the exclusion criteria. Two investigators proofread the data to ensure data accuracy. Inappropriate responses are discarded. For the semi-structured interviews, materials are also transcribed and validated by two investigators. The interview is terminated when no new themes emerge, and it is believed to achieve data saturation.

Data analysis: SPSS22.0 is used for data processing and analysis. Calculation data is described as frequency and percentage. Multiplechoice questions are analyzed by prevalence rate and response rate. On the premise of measurement data conforming to the normal distribution through normality test, the mean standard deviation is used for statistical description, and the non-parametric test is used for the non-normal distribution. When comparing two groups, the independent sample t test is used. The analysis of variance is used to compare multiple groups. The difference is statistically significant if p<0.05. Multivariate linear regression analysis is used to analyze the influencing factors (ain = 0.05; aout = 0.10). The qualitative study has adopted the Colaizzi analysis method [15]. Themes and sub-themes are identified, clustered, and reported.

Results

328 nurses have participated in the survey with 298 valid responses at a return rate of 90.85%. Demographic information of survey respondents is shown in Table 1.
