GIS mapping as a public health tool has been increasingly applied to chronic disease control. While evaluating TIA incidence from an existing regional stroke registry in Ludhiana city, India, we aim to apply the innovative concept of regional TIA GIS mapping for planning targeted stroke prevention interventions.
TIA patient data was obtained from hospitals, scan centers and general practitioners from March 2010 to March 2013 using WHO-Stroke STEPS based surveillance as part of establishing a population-based stroke registry in Ludhiana city. From this registry, patients with TIA (diagnosed by MRI image-based stroke rule-out, or clinically) were chosen and data analyzed.
A total of 138 TIA patients were included in the final analysis. The annual TIA incidence rate for Ludhiana city was 7.13/100,000 (95% confidence interval: 5.52 to 8.74) for 2012-2013. Mean age was 58.5 ± 13.9 years (range: 22-88 years) and 87 (63%) were men. Majority of the TIA cases had anterior circulation TIAs. Hypertension (87.4%) was the most common risk factor. Using Geographic Information System (GIS) mapping, high TIA incidence was seen in central, western, and southern parts and clustering of TIA cumulative incidence was seen in the central part of Ludhiana city.
Incidence rate of TIA was lower than that expected from a low- and middle-income country (LMIC). TIA GIS mapping, looking at regional localization, can be a novel option for developing targeted, cost-effective stroke prevention programs.
地理信息系统（GIS）绘图作为一种公共卫生工具，已越来越多地应用于慢性病控制。在评估印度卢迪亚纳市现有区域卒中登记处的短暂性脑缺血发作（TIA）发病率时，我们旨在应用区域TIA GIS绘图这一创新概念来规划有针对性的卒中预防干预措施。
2010年3月至2013年3月期间，作为在卢迪亚纳市建立基于人群的卒中登记处的一部分，使用基于世界卫生组织卒中监测步骤（WHO-Stroke STEPS）的监测方法，从医院、扫描中心和全科医生处获取TIA患者数据。从该登记处中选择TIA患者（通过基于MRI图像的卒中排除法或临床诊断）并进行数据分析。
最终分析共纳入138例TIA患者。2012 - 2013年卢迪亚纳市的年TIA发病率为7.13/10万（95%置信区间：5.52至8.74）。平均年龄为58.5±13.9岁（范围：22 - 88岁），男性87例（63%）。大多数TIA病例为前循环TIA。高血压（87.4%）是最常见的危险因素。使用地理信息系统（GIS）绘图发现，TIA高发病率出现在中部、西部和南部地区，并且在卢迪亚纳市中部出现了TIA累积发病率的聚集情况。
TIA发病率低于低收入和中等收入国家（LMIC）的预期水平。考虑区域定位的TIA GIS绘图可为制定有针对性的、具有成本效益的卒中预防计划提供一种新选择。
