Background
We assessed the possible impact of provision of reverse osmosis (RO) water on the incidence of hospital diagnosed CKD/CKDu in North Central Province (NCP) of Sri Lanka.
Methods
An ecological study was conducted on data from 2010–2020 on the incidence of hospital diagnosed CKD/CKDu, CKD/CKDu screening and provision of drinking water RO plants in NCP. Analysis was conducted using descriptive statistics, ANOVA and chi-square test.
Results
The annual incidence of hospital diagnosed CKD/CKDu (per 100 000 population) in 2010–2013, 2014–2016 and 2017–2020 periods in Anuradhapura district were 129.07, 331.06 and 185.57 (p = 0.002) while in Polonnaruwa district these were 149.29, 326.12 and 296.73 (p = 0.04) respectively. In NCP provision of RO plants commenced after 2011 and the decline in the incidence of hospital diagnosed CKD/CKDu was seen in 25 of the 29 Divisional Secretary Divisions when more than 20% of the families received access to drinking RO water projects.
Conclusions
The annual incidence of hospital diagnosed CKD/CKDu increased in NCP from 2010 to 2016 and continuously decreased thereafter. Continuous declining of CKD/CKDu incidence was seen after more than 20% of the families received access to drinking water RO plants.
