Latar Belakang: Stroke merupakan kondisi yang terjadi ketika pasokan darah ke suatu bagian otak tibatiba terganggu, karena sebagian sel-sel otak mengalami kematian akibat gangguan aliran darah karena sumbatan atau pecahnya pembuluh darah otak. Tujuan: Untuk mengetahui hubungan pengetahuan dan sikap keluarga terhadap kemampuan deteksi dini serangan stroke iskemik akut pada penanganan prehospital di Wilayah Kerja Puskesmas Gianyar I Metode: Penelitian ini menggunakan desain analitik korelasi dengan metode pendekatan cross-sectional. Populasi dalam penelitian ini yaitu keluarga yang ada di Wilayah Kerja Puskemas Gianyar I dengan jumlah sampel sebanyak 144 responden dengan metode total sampling. Instrumen penelitian yang digunakan yaitu kuesioner pengetahuan, sikap dan kemampuan deteksi dini. Data dianalisis menggunakan Spearman-rho. Hasil: Hasil uji statistik Spearman rho p-value=0,005 yang berarti ada hubungan pengetahuan dengan kemampuan deteksi dini. Dengan correlation coefficient yaitu 0,231 yang berarti memiliki kekuatan korelasi yang lemah dan arah hubungan positif maka semakin tinggi pengetahuan, maka kemampuan deteksi dini semakin baik. Hasil uji statistik Spearman rho p-value=0,011 yang berarti ada hubungan sikap dengan kemampuan deteksi dini. Dengan correlation coefficient yaitu 0,212 yang berrarti memiliki kekuatan korelasi yang lemah dan arah hubungan positif maka semakin baik sikap, maka kemampuan deteksi dini juga semakin baik. Kesimpulan: Diharapkan penelitian ini dapat menjadi dasar dalam pemberian edukasi bagi masyarakat pada pencegahan tingkat keparahan stroke dengan deteksi dini tanda gejala awal serangan stroke iskemik akut sebelum dibawa kerumah sakit Kata Kunci: Pengetahuan, Sikap, Keluarga, Kemampuan Deteksi Dini, Stroke

Background: Stroke is a condition that occurs when the blood supplies to a part of the brain are suddenly disrupted, because some brain cells experience death due to disruption of blood flow due to blockage or rupture of cerebral blood vessels. Purpose: To determine the correlation between knowledge and family attitude toward the ability to early detection of acute ischemic stroke in prehospital care in the working area of public health center Gianyar I Methods: This study employed analytic correlation design with cross-sectional approach. The population of this study were families in the Working Area of Public Health Center Gianyar I. There were 144 respondents recruited as sample of the study which were selected by using total sampling method. The data were collected by using knowledge questionnaires, attitudes and early detection skills. The data were analyzed by using Spearman-rho test. Results: The finding showed that there was a correlation between knowledge and the ability to early detection with p-value = 0.005. The correlation coefficient was 0.231 which meant positive direction, the higher the knowledge, the better the ability to early detection. Spearman rho statistical test showed p-value = 0.011 which meant there was a correlation between attitude and ability to early detection. With a correlation coefficient of 0.212 which meant that it had a weak correlation and a positive relationship direction, the better the attitude, the better the ability to early detection. Conclusion: It is expected that this study will serve as a foundation for educating the public about preventing the severity of strokes by identifying acute ischemic stroke symptoms early on before patients are admitted to the hospital.
