| Abstract|| |
Background: The rising incidence of stroke in India indicates the importance of evaluating the existing knowledge, attitude, and practice (KAP) in the community, which is essential for stroke control. Objective: To explore and compare stroke-related KAP among participants from stroke-affected families (SAFs) and nonstroke-affected families (NSFs). Design: Using stratified random sampling, a three-phase house-to-house survey was conducted in Kolkata, West Bengal, India. First, field investigators screened subjects of stroke; second, the neurologist confirmed positive cases; and third, under supervision of the neuropsychologist, a validated questionnaire on KAP was administered to participants from SAFs and age-matched NSAFs from the same neighborhood. Results: The KAP questionnaire was administered to 282 participants each from both groups. Knowledge about stroke prevailed in 97% participants and was significantly higher in the SAF group. Both SAF and NSAF groups had better knowledge about prominent symptoms of stroke (loss of consciousness and paralysis) and admitted it as emergency situation requiring hospitalization and that it was potentially preventable. Those persons belonging to the SAF group, however, had lesser knowledge of the risk factors such as diabetes (P < 0.001), smoking (P < 0.014), alcoholism (P < .0.0001), family history (P < .0.0001) and mild stroke symptoms such as headache, (P < 0.001), vomiting (P < 0.001), and fits (P 0.003) as compared to the NSAF group. Conclusions: Persons from both SAF and non-SAF groups are aware about stroke but possess lesser knowledge about the many symptoms of stroke and risk factors, indicating the necessity of enhancement of existence knowledge on symptoms for better diagnosis and of risk factors for better prevention.

| Introduction|| |
Stroke is a major public health problem worldwide. The stroke burden in India has been rising over the past few decades , in comparison to the developed countries where it has reached a plateau or is decreasing. It is estimated that at present, approximately 1.8 million Indians out of a population of 1.2 billion suffer from stroke every year and about one-third of them die annually while another one-third are left with some permanent disability. These statistics underscore the urgency with which the phenomenon of stroke needs to be studied in India with the goal of reducing the huge stroke burden that the country is facing.
Without public knowledge and the right attitude and practices, stroke burden cannot be reduced. For instance, it is important to know that therapeutic opportunities in stroke are limited. Thrombolytics can be used only within the window period, for which early identification of the signs and symptoms of stroke is essential. Delay in hospitalization contributes to high mortality and morbidity in stroke but ignorance about stroke symptoms, poor infrastructure, and hesitancy about hospital admission even when infrastructure and access are available often leads to delay. Further, there is a lack of knowledge and indifference about that timely treatment of hypertension and appropriate lifestyle changes that may help to decrease the incidence of stroke and morbidity among stroke-survivors in the long run.
Studies on the knowledge, attitude, and practice (KAP) of stroke have mostly been undertaken in developed countries over the last two decades.,,,,,,, Studies from Asia have been undertaken in developed countries such as South Korea and Hong Kong in China , and in some developing countries such as Brazil, Myanmar, Iran, Oman, Pakistan, and India.,,,,,, The salient characteristics of these studies have been summarized in [Table 1].

This study attempts to explore and compare the KAP of stroke among members in stroke-affected families (SAFs) and nonstroke-affected families (NSAFs) in an urban setting in Kolkata, West Bengal, India. The results are intended to help in the planning of community-based stroke prevention and management strategies.
| Materials and Methods|| |
The study was conducted between November 2006 and September 2007 as a house-to-house, cross-sectional study in Kolkata, West Bengal, India — the largest metropolitan city in eastern India. The municipal limits of Kolkata cover a heterogeneous population of 4.58 million  with Bengali as the predominant language spoken followed by Hindi. The literacy rate is 85%. Hindus (74.7%) comprise the predominant religious group followed by Muslims (23.6%), Sikhs (0.08%), Christians (0.56%), and others. The study protocol was approved by the Institutional Ethics Committee of the Institute of Postgraduate Medical Education and Research (IPGME&R), Kolkata, West Bengal, India. Written informed consent was obtained from each study subject before collecting data.
The municipal area of Kolkata has been demarcated into 5,200 blocks by the National Sample Survey Organization (NSSO) of the Government of India. The NSSO database provides complete information regarding the geographical location, boundaries, type of housing, and slum areas in each block. For sampling purposes, the city was divided into six strata based on the geographical location and presence of slum areas. We deliberately studied the slum or disadvantaged population since this segment constitutes 30-40% of the urban population in India. The dwellers in these areas are socioeconomically disadvantaged with respect to relatively affordable dwellers. A total of 282 blocks were randomly selected from the six strata and 50% of households in each block were surveyed by visiting alternate houses. This allowed a screening of urban individuals from diverse ethnic and educational backgrounds. This study was part of a larger study of stroke (issue of KAP is being reported here) and the principles of sampling strategy have been reported earlier.
The survey procedure is depicted in [Figure 1]. In the first stage, households were screened for stroke cases by four field investigators who had been adequately trained by doctors in the understanding of stroke and administration of “family screening questionnaire” for stroke. Our operational definition of stroke was “rapidly developing clinical signs of focal or global disturbance of cerebral function, with symptoms lasting 24 hours or more or leading to death, with no apparent cause other than vascular origin.” The family screening questionnaire is a validated tool that was reported earlier. In the second stage, a doctor confirmed screen-positive cases through clinical examination and recorded further clinical details. For inclusion, all sampled individuals had to be residents of Kolkata, West Bengal, India for at least 1 year and with at least one reliable family informant to provide relevant information. Subjects with transient ischemic attacks were excluded. The doctor also randomly examined 10% of screened-negative households in each block to unearth false negative cases. In the third stage, the field investigators, under supervision of the neuropsychologist, administered the KAP questionnaire. The instrument was administered to caregiver respondents from stroke families as well as age-matched (±3 years) individuals from nonstroke families from the same block who served as controls. “Knowledge” implied general awareness regarding stroke and information about the signs and symptoms of stroke and its risk factors; “attitude” indicated the outlook toward stroke; and “practice” related to behavior in the face of potential stroke events. The frequency of caregivers who responded to the above questionnaires was recorded.
Considering a neurologist's diagnosis as the gold standard, the “family screening questionnaire” used for detecting stroke cases had a sensitivity of 83.3% and specificity of 99.9%. The KAP questionnaire consisted of 16 main questions out of which 6 had subquestions varying from numbers 2 to 8 [Table 2]. The participants were expected to answer options of “yes,” “no,” or “uncertain.” Out of these questions, four had strong intrarater agreement [intraclass correlation coefficient (ICC) > 0.7], nine had good agreement (ICC 0.6–0.7), and the remaining three had ICC < 0.6. The latter were modified appropriately. One question that was related to sexual activities was omitted. Regarding interrater agreement, all questions had strong agreement (ICC values > 0.9) barring two that had good agreement (ICC = 0.644).

The data have been summarized by routine descriptive statistics, namely, the mean and standard deviation for numerical variables and counts and percentages for categorical variables. Numerical variables have been compared between groups by Student's independent samples t test. Chi-square test or Fisher's exact test has been applied for intergroup comparison of categorical variables. Comparisons have been two-tailed and P< 0.05 has been considered to be statistically significant. Intrarater and interrater validations of the KAP questionnaire was done on 50 respondents (25 from SAFs by two raters). ICC was calculated by appropriate coding of responses. In order to be acceptable, the minimum ICC value had to be 0.6.
| Results|| |
Over the 1-year period of the study, 284 SAFs were identified out of whom 282 consented to participate in the KAP survey. The corresponding 282 neighborhood NSAFs were interviewed as controls after approaching 341 such families. The participants from the NSF group were age-matched with the participants of the SAF group (mean ± standard deviation: 42.5 ± 14.03 years in the SAF group; 43.2 ± 14.04 years in the NSF group; P = 0.549) but were not matched in terms of gender. There were 217 female respondents (76.95%) in the SAF families compared to 148 females (52.48%) in the NSAF families (P< 0.001). There was a significant difference in the number of years of formal education between respondents from the two groups (7.8 ± 4.73 years in SAFs; 10.1 ± 4.06 years in NSFs; P = 0.004).
The different groups who provided care and responded to questionnaires were as follows: Wife-32.9%, son-19.2%, daughter-16.7%, daughter-in-law-16.7%, mother-2.1%, husband-3.19%, sister-4.8%, niece-1.41, mother in law-0.7%, and sister-in-law-1.77%.
Differences in the KAP of stroke between the SAFs and NSAFs are presented in [Table 2]. Knowledge about stroke was high among both participating groups but was significantly higher among SAF participants. More participants in the SAF group reported to have heard or read about stroke (P = 0.004), were aware about stroke paralysis (P = 0.007), knew people who have had stroke (P< 0.001), and had even witnessed cerebral attack (P< 0.001).
A varied picture emerged about the knowledge of signs, symptoms, and risk factors of stroke among the study participants. A large percentage of both cohorts were aware about the loss of consciousness or paralysis being associated with stroke and they did not differ in this respect. However, there was less knowledge regarding headache, vomiting, and fits being associated with stroke; moreover, knowledge of these risk factors was even poorer in SAFs. However, both SAFs and NSAFs had a substantial and similar amount of knowledge in that stroke was an emergency and that there was an urgent period within which medical attention was necessary so as to improve the prognosis. A substantial fraction in both the cohorts agreed that hypertension and diabetes mellitus were important factors that predispose to stroke but most were unaware of other important risk factors such as age, obesity, smoking, alcoholism, and family history. The knowledge level was significantly better in NSAFs for most of these risk factors. Interestingly, about 80% of SAF participants considered stroke to be noninfectious in contrast to about 65% in the NSAF group (P< 0.001).
The data revealed close similarity regarding the attitude toward stroke among the two groups. About 70% of the participants in both groups generally agreed that stroke was preventable through control of risk factors but affected families were more optimistic that return to work was possible for stroke survivors. They were also more inclined to agree that precautions were necessary only after a primary stroke event.
Regarding practice, the large majority of the study participants agreed that it was important to get the patient to hospital as soon as possible rather than wait for a spontaneous recovery, and this view was stronger in stroke-affected families. Calling a doctor was also considered important by around 40% of the families. Prevention was considered a better option than treatment by both groups and they did not differ significantly in this regard. A large section (78.72%) of stroke-affected participants felt that medication and physiotherapy together were useful for managing the stroke event while this figure was 63.83% for nonaffected families (P< 0.001).
| Discussion|| |
This community-based survey utilized a sample selected through careful stratified random sampling to ensure that various sections of the city's large population were represented. People residing in urban disadvantaged areas belong to lower socioeconomic strata and we had adequate representation of both slum and nonslum dwellers in the sample studied. Affected families were identified using a reliable screening instrument backed up by expert neurological opinion. The KAP survey was conducted under the supervision of the neuropsychologist. These elements represent the strengths of our study and should enhance the validity of the findings.
The results indicate that in general, study participants from both stroke-affected and non-affected families were aware of the basic connotations of the term “stroke” and its association with paralysis. This may be an indirect indicator of the relatively high incidence and prevalence of stroke in the study population. The knowledge regarding warning signs and symptoms of stroke and stroke risk factors was inadequate. In line with previous Indian reports,, comparatively better knowledge prevailed about stroke symptoms than risk factors. Generally, the attitudes toward stroke were in agreement between the SAF and NSAF groups. However, they differed on issues regarding poststroke reemployment and prestroke prevention strategies. Overall, the practice choices such as early hospitalization, therapeutic intervention in the window period, and a preference for combination of drug therapy and physical rehabilitation after stroke were encouraging.
Participants from both the SAF and NSAF groups could well-identify paralysis and loss of consciousness as related to stroke but not headache, vomiting, or fits. Unconsciousness and paralysis are usually dramatic, acute onset symptoms where the patient remains incapacitated for variable periods and therefore, are perceived as serious. On the other hand, headache and vomiting without other accompanying acute neurological signs may be events commonly experienced due to migraine and are hence, perceived as not so threatening and tend to be ignored. Fits, due to their association with epilepsy, which is also a common problem in India, are considered to be an accompaniment of stroke by only a minority.
Better knowledge about the signs and symptoms in comparison to the knowledge about multiplicity of risk factors is a matter of concern since it raises the possibility that the public attach more importance to firefighting the problem rather than its prevention. We stressed on the commonly understood risk factors such as high blood pressure, diabetes, smoking, alcoholism, and family history and did not even ask for factors such as atrial fibrillation and carotid stenosis, which would have been incomprehensible to the majority. Without knowledge of risk factors and the understanding that many of them can be favorably modified, stroke prevention will remain an unmet challenge in our community. This ignorance and lack of knowledge seemed to be greater in the stroke families and this, in fact, could be the contributory factor as to why stroke occurred in these families. Overall, the participants were well aware about hypertension and partially aware about diabetes as risk factors; the knowledge regarding diabetes was less in the SAF group, which is in contrast to a study from rural India. Smoking was identified as a risk factor by only one-third of our participants, which is similar to other studies globally ,, although smoking was considered important by participants in the earlier Indian study. A smaller proportion of respondents in our study identified alcoholism as a stroke risk factor, which is in consistence with an American study  and in contrast to a French one. Overall, the general impression from this study would be that the level of knowledge regarding risk factors is moderate in relation to age, gender, diabetes, smoking, alcoholism, and family history that has been similarly observed in earlier studies in a few developed and developing nations.,, This ignorance is not bliss and needs to be addressed urgently through public awareness campaigns if stroke prevention strategies are to be implemented.
Knowledge that stroke is an emergency demanding prompt medical management, and acknowledgement that a negative aftermath can be prevented through early hospitalization and therapeutic intervention in the window period in contrast to the belief that physical rest or spontaneous recovery could be the correct practice for stroke management is substantially present among respondents in the present observation. The speed of hospitalization after stroke depends on the level of knowledge about stroke. However, inadequate knowledge regarding the presenting signs and symptoms of stroke can delay recognition and therefore, hospitalization. Knowledge that stroke demands immediate medical attention with proper medical facilities is voiced by people globally.,, Strong advocacy for urgent hospitalization will not be effective in reducing mortality and morbidity if stroke knowledge, coupled with improvement in infrastructure and logistics for transporting patients to hospitals at odd hours, is improved.
The current study reveals responders to be open to a scientific approach for recovery from stroke comprising both medication and physiotherapy in contrast to folk remedies such as oil massage, faith healing, and magic. The improved attitude observed could be the consequence of greater exposure to stroke cases in the general population due to its increased prevalence and/or awareness of management strategies prescribed by doctors.
Overall, our participants show a conservative attitude regarding reemployment after stroke, where only the SAF group is optimistic about it. This is an issue that merits deeper exploration since financial self-sufficiency is possible through reemployment and is strongly related to stroke rehabilitation. The optimism in the SAF group may be due to various factors such as the relief related to surviving from stroke and the realization and therefore, determination to seek reemployment to look after families, procure medicines, and continue physiotherapy. In contrast, NSAFs are possibly aware that stroke requires long-term, complex, multidisciplinary treatment and recovery may not be absolute after observing cases from the neighborhood. We did not find data to compare this issue with earlier studies.
The limitation of this study is that we had a small sample size. Increase in the sample size could possibly further establish our finding. Possibly, repeat data collection from the participants of both groups after proper training or educational intervention about enhancing stroke-related knowledge could be useful for field implementation. This needs a longitudinal design. The information may vary from the persons who have been interviewed depending on the level of closeness of the relationship with the stroke-related person and his/her level of intelligence.
In conclusion, we can say that this study shows better knowledge about stroke in both SAFs and NSAFs. The common symptoms identified for stroke were paralysis and loss of consciousness but other symptoms such as headache, vomiting, and fits were less recognized and this might contribute to delay in diagnosis and hospitalization. Knowledge about a few risk factors are present in both the groups, notably, hypertension followed by diabetes mellitus. However, knowledge about other risk factors such as smoking, obesity, age, and gender is poor. This emphasizes the need to increase knowledge regarding risk factors, which will benefit the community at large as well as SAFs since there is always a possibility of stroke recurrence. The importance of early hospitalization and the need for both medicines and physiotherapy can be reinforced and this needs to go hand-in-hand with improvement of hospitalization and transport facilities. Such community-based measures are likely to be as important as efficient in-hospital management toward reduction of the stroke burden in our setting.
