The completeness and accuracy of verbal-hypertension risk screening report in 4 provinces, Thailand, 2015

Abstract

Background: Hypertension is one of the major causes of death in the world. Thailand found the increasing trend of hypertension as 2nd leading cause of death. There was ongoing verbal screening every year. The screening coverage of more than 90% was expected. However, it still lacks of the study of completeness and accuracy of information. The objectives were to study data completeness and accuracy of verbal-hypertension risk screening data reporting in 2015 collected from 16 Sub-district health promoting hospitals in 4 provinces.
Methods: Cross-sectional study with stratified random sampling was done among population age over 15 years old who received annual verbal-hypertension risk screening between 1st October 2014 to 31st March 2015. The 1,152 samples were collected from 16 sub-district health promoting hospitals in Chiang-Rai, Uttaradit, Surat-Thani and Si-Sa-Ket. Information in screening records was compared with 2 reports of 43 files including PERSON and NCDSCREEN files.
Results: Overall screening coverage in 4 provinces was 78.77%. Considering that by province, the screening coverage of Uttaradit province 88.02%, Si-Sa-Ket 81.44%, Surat-Thani 75.77%, and Chiang-Rai 73.02%. The overall completeness of variables of gender, age and sub-district was 98.96%, 98.78%, and 53.30%. With those corresponding, the overall accuracy was 99.39%, 99.30% and 99.68%. The completeness of diastolic blood pressure, systolic blood pressure, waist circumference, height, weight, and family history was 67.45%, 67.27%, 63.80%, 56.25%, 47.48%, and 17.1%. The completeness of diastolic blood pressure, systolic blood pressure, waist circumference, height, and weight was 73.03%, 71.76%, 73.65%, 68.72%, and 78.71%. Considering total targeted population, the percentage of data of diastolic blood pressure, systolic blood pressure, waist circumference, height, and weight which is available and accurate was 38.8, 38.0, 37.0, 30.4, and 29.4.
Discussion and Conclusion: The screening coverage in the 4 provinces was lower than central policy’s requirement. Almost one-third of record of screened people did not have information of blood pressure which is the crucial information for risk assessment. About half of records did not show information of height and weight which are also essential for risk assessment. Crudely, the percentage of data available and accurate was about 30–40 among total targeted population.
