The paper “The incomparability of cause of death statistics under “one country, two systems”: Shanghai versus Hong Kong” has been published on Population Health Metrics (impact factor of 2.91)by Professor Jiaying Zhao （first author）of ADRI, School of Sociology and Political Science, Shanghai University and two professors with Shanghai University as the first institute on 29th Sep,2017, ranking 15/157 .
The emphasis of this paper is about whether socio-institutional factors will affect the difference on COD. Valid and comparable cause of death (COD) statistics are crucial for health policy analyses. Variations in COD assignment across geographical areas are well-documented while socio-institutional factors may affect the process of COD and underlying cause of death (UCD) determination. This study examines the comparability of UCD statistics in Hong Kong and Shanghai, having two political systems within one country, and assesses how socio-institutional factors influence UCD comparability. Quantitative、qualitative and thematic analyses were used.
Variations in socio-institutional factors were related to the process of certifying and registering COD in Hong Kong and Shanghai. To improve regional data comparability, health authorities should develop standard procedures for registering deaths outside hospital, provide guidelines and regular training for doctors.
