"Latar Belakang: Dalam diagnosis varises vena tungkai bawah (VVTB), venous clinical severity score (VCSS) merupakan alat bantu diagnosis VVTB yang praktis, cepat, dan dapat dikerjakan oleh semua tenaga kesehatan termasuk perawat. Hingga saat ini belum ada peneliti yang melakukan validasi eksterna penilaian VCSS yang dikerjakan oleh perawat di Indonesia.Tujuan: Mengetahui tingkat ketepatan metode skor VCSS oleh perawat dibandingkan dengan komponen klinis (C) klasifikasi clinical-etiology-anatomy-pathophysiology (CEAP) oleh dokter spesialis bedah vaskular.Metode: Studi cross-sectional ini mengikutsertakan 63 orang perawat instalasi bedah pusat RS Dr. Cipto Mangunkusumo tanpa varises sebelum menjadi perawat sebagai sampel yang diambil secara consecutive Penilaian VCSS dilakukan dengan komponen klinis klasifikasi CEAP sebagai pembanding. Variabel dianalisis dengan uji Chi-square, dilanjutkan dengan uji nilai sensitivitas, spesifisitas, nilai duga positif (NDP), nilai duga negatif (NDN), likelihood ratio dan akurasi skor diagnostik, termasuk analisis uji diagnostik menggunakan indeks Youden.Hasil: Prevalensi VVTB pada studi ini berdasarkan skor VCSS adalah 9,5%. Korelasi antara klasifikasi CEAP dan VCSS ditemukan bermakna (p<0,05). Derajat VVTB antara klasifikasi CEAP dan VCSS berhubungan secara signifikan (p <0,05). Pada cut-offVCSS 2 didapatkan nilai sensitivitas 66,67%, spesifisitas 66,67 %, NDP 32,0%, NDN 89,47%, likelihood ratio (+) sebesar 2,00, likelihood ratio (-) sebesar 0,50, dan akurasi 66,67%.Kesimpulan: Skor VCSS memiliki akurasi lemah terhadap komponen klinis (C) klasifikasi CEAP untuk menegakkan diagnosis VVTB.

Background: In the diagnosis of lower leg varicose veins (LLVV), the venous clinical severity score (VCSS) is practical, fast, and can be done by all health workers including nurses. Until now there has been no researcher who has conducted external validation of the VCSS assessment carried out by nurses in Indonesia.

Aim: To determine the accuracy of the VCSS scoring method by nurses compared to clinical component (C) of the clinical-etiology-anatomy-pathophysiology (CEAP) classification by vascular surgeons.

Method: This cross-sectional study included 63 nurses at the central surgical installation of Cipto Mangunkusumo Hospital without varicose veins before becoming a nurse as a consecutive sample. The VCSS assessment was carried out with the clinical component of CEAP classification as a comparison. Variables were analyzed by the Chi-square test. Followed by testing the value of sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), likelihood ratio, and accuracy of diagnostic scores, along with the ROC analysis using Youden Index.

Results and Discussion: The prevalence of LLVV in this study is 9,5%. Bivariate analysis of CEAP and VCSS has a significant correlation (p <0,05). The degree of LLVV with CEAP and VCSS is related significantly (p <0,05). With VCSS cut off at scores of 2, the sensitivity is 66.67%, the specificity is 66.67%, the PPV is 32,0%, the NPV is 89.47%, the positive and negative likelihood ratio are 2.00 and 0.50, and the accuracy value is 66.67%.

Conclusion: The VCSS score has weak level of accuracy against the clinical component (C)  of CEAP classification for diagnosing VVTB."

"Written by a stellar line up of experts in their field. The book takes the reader on a very informative and detailed journey through many foot entities and everything from aetiology, risk factors, imaging, physiotherapy and pharmacology is covered for each." "Reviewed by Tobias Bremer on behalf of In Touch, July 2015. This book is able to give a very detailed 'gold standard' education for the covered conditions."

"Latar Belakang. Proses pembuatan kain tapis membutuhkan waktu lama dan ketelitian tinggi. Pekerja bekerja dengan menggunakan peralatan sulam tenun tradisional yang tidak memperhatikan aspek ergonomi. Proses menyulam dilakukan dengan posisi duduk bersila di lantai mengakibatkan timbulnya ketidaknyamanan tungkai dan berdampak pada produktivitas sulam. Penelitian ini bertujuan untuk memperoleh kursi meja kerja yang ergonomis dan melihat pengaruhnya terhadap penurunan skala ketidaknyamanan tungkai dan peningkatan produktivitas sesudah intervensi pada pekerja kain tapis.Metode Penelitian. Desain yang digunakan adalah eksperimental one group pre-post intervensi dengan pembuatan media intervensi berupa kursi meja yang ergonomis. Sampel diambil menggunakan metode cluster sampling perusahaan tapis. Pada penelitian dilakukan pengumpulan data skala VAS ketidaknyamanan dan panjang sulam setiap akhir kerja. Analisis data dilakukan dengan program statistik SPSS Statistics 20.0.Hasil Penelitian. Telah didapatkan kursi meja kerja yang ergonomis bagi pekerja sulam tapis. Median skala VAS ketidaknyaman tungkai sebelum intervensi sebesar 7,0 4,5-8,5 . Median skala VAS ketidaknyamanan tungkai sesudah intervensi sebesar 1,0 0,5-1,5 . Median selisih skala VAS ketidaknyamanan sebelum dan sesudah intervensi sebesar 6,0 3,0-7,5 p

Background. The process of making a tapis takes a long time with high accuracy. Workers work using traditional embroidering equipment that does not pay attention to the ergonomics aspect. The embroidering process is done by sitting cross legged on the floor resulting in legs discomfort and impact on the work productivity. This study aims to get an ergonomic working desk chair for embroidering tapis cloth and see its effect on decrease the lower limb discomfort visual analogue scale VAS score and increase the productivity of tapis cloth workers after the interventionMethod. The study design was an experimental one group pre post intervention with the creation of intervention media in the form of ergonomic desk chair. Samples were taken using cluster sampling on tapis companies in Bandar Lampung City. The lower limb discomfort VAS score and length of tapis cloth at the end of work before and after the intervention were compared. Data analysis was performed by SPSS Statistics 20.0 statistics program.Results. An ergonomic working desked chair for embroidering tapis cloth is available. The median interquartile range of lower limb discomfort VAS score before the intervention was 7.0 4.5 8.5 . The median of lower limb discomfort VAS score after the intervention was 1.0 0.5 1.5 . The median of lower limb discomfort VAS score difference before and after the intervention was 6.0 3.0 7.5 p"
