Aga Khan University322 enrolled

Overview

This is a validation study. A stroke symptom questionnaire will be adapted and translated into local language. Two community health workers will be trained in its administration. Their findings will be validated against assessment by two neurologists. The study hypothesis is that the chance corrected agreement between the community worker administered stroke symptom questionnaire and the assessment by neurologist based on history and physical examination is at least moderate.

Overall Objective: To translate, adapt and validate a stroke symptom questionnaire for identification of stroke symptoms by community health workers ( CHW) in a peri-urban Pakistani community Specific Aims: 1. To translate and adapt a stroke symptom questionnaire for identification of stroke symptoms by community workers in a peri-urban Pakistani community 2. To validate community workers administered stroke symptom questionnaire against assessment by neurologist in a peri-urban Pakistani community 3. To determine the feasibility of utilizing community workers for identification of stroke patients in the community in terms of subject refusals and difficulty in understanding questions The study will be conducted at the community site of AMAN community health project in Ibrahim Hyderi. Community health workers will systematically select households and from them individuals meeting eligibility criteria will be interviewed. Community workers will administer stroke symptom questionnaire to them at their homes. Those unable to answer will have a surrogate answering for them. In the second part of the study, two neurologists will independently assess all individuals. The purpose of this would be to validate the findings of the community workers based on the stroke symptom questionnaire.

Outcomes

Primary Outcomes

Validity

This was a validation study in which we calculated the sensitivity, specificity and predictive values for CHW administered questionnaire against assessment by two neurologists. We also assessed the chance corrected agreement (kappa) for the same.

Time frame: Cross-sectional , All interviews within 4 Weeks ( CHW and Neurologist)

Secondary Outcomes

Feasibility

We assessed the feasibility of utilizing CHWs for stroke screening in terms of time taken to fill out questionnaire, difficulty in understanding questions and subject refusals

Time frame: Cross sectional - All interviews within 4 weeks( CHW and Neurologists)
