Decreasing incidence of hospital diagnosed CKD/CKDu in North Central Province of Sri Lanka: is it related to provision of drinking water reverse osmosis plants?

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.

Healthy Lifestyle Centres: a service for screening noncommunicable diseases through primary health-care institutions in Sri Lanka.

The Ministry of Health in Sri Lanka initiated the Healthy Lifestyle Centres (HLCs) in 2011, to address the lack of a structured noncommunicable disease (NCD) screening service through the lowest level of primary health-care institutions. The main service objective of the HLCs is to reduce the risk of NCDs of 40-65 year olds by detecting risk factors early and improving access to specialized care for those with a higher risk of cardiovascular disease (CVD). The screened clients are managed at HLCs, based on the total-risk approach to assess their 10-year CVD risk, using the World Health Organization/International Society of Hypertension risk-prediction chart. Those with a 10-year CVD risk of more than 30% are referred to the specialized medical clinics, while others are managed with lifestyle modification and are requested to visit the HLC for rescreening, based on the levels of CVD risk and intermediate risk factors. Identified challenges to date include: underutilization of services, especially by men; weak staff adherence to protocols; lack of integration into pre-existing NCD-screening services; non-inclusion of screening for all the major NCDs; and human resources. The government plans to address these challenges as a priority, within the context of the National multisectoral action plan for the prevention and control of NCDs in Sri Lanka 2016-2020. Key interventions include: extended opening hours for HLCs, outreach activities in workplaces, and integration with "well woman clinics". Costs related to actions have been realistically estimated. Some actions have already been initiated, while others are being designed with identified funds.
