Pengaruh Validitas Dan Reliabilitas Metode Sahli Terhadap Metode Cyanmethemoglobin Sebagai Alat Skrining Anemia di Wilayah Kerja Puskesmas Sialang Buah Kabupaten Serdang Bedagai Tahun 2019
Maternal Mortality Rate (MMR) in Indonesia is still high at 305 per 100,000 live births and is above the target of Sustainable Development Goals (SDGs) of 70 per 100,000 live births. The main cause of maternal death is bleeding caused by anemia. The prevalence of anemia in pregnant women in Sialang Buah Health Center is quite high in 2018 which is 40.7% and has increased from 2017 (40.5%) and 2016 (32.3%). This study aims to determine the prevalence of anemia in pregnant women in 2019 through screening. It is also tested the validity and reliability of the screening tool. This study was conducted in June-July 2019 using a descriptive observational design. The sample was all pregnant women who made antenatal visits at the Sialang Buah Health Center with a sample size of 62 people. Pregnant women were interviewed with a questionnaire to find out their characteristics, then venous blood was taken. Blood Hb levels were examined using a screening tool (Sahli Method) and Gold standard (Cyanmetahemoglobin Method). They were declared anemia if blood Hb level is ≤ 11gr/dl. Then the examination results were analyzed to determine the prevalence, sensitivity and reliability. Of the 62 pregnant women screened there were 26 people who were anemic (prevalence rate = 41.9%). Most of the pregnant women were aged 20-35 years, that were 18 people (69.2%), Their education were junior high school level tht were 13 people (50.0%), mothers who work as housewives that were 24 people (92.3% ), and mothers with the first pregnancy that were 10 people (38.5%). The validity of the screening tool showed sensitivity 61.53%, specificity 75.0%, positive predictive value 64.0%, negative predictive value 72.97%. Reliability testing shows the value of the Cohen Kappa agreement coefficient of 0.37 (indicating a weak agreement). The prevalence of anemia in pregnant women in the working area of Sialang Buah Health Center was quite high. It is expected that the health center officers will immediately take care of pregnant women who are anemia and do counseling related to the danger of anemia. The value of the sensitivity and specificity of the screening tool is quite high and the reliability value is considered weak. The Sahli method is considered less feasible for anemia examination at the Sialang Buah Health Center and is recommended to use the Cyanmethemoglobin method.
