Understanding the impact of local funding cuts on environmental health and regulatory services and gastrointestinal infection outcomes: a longitudinal ecological study protocol

Abstract

Background: Gastrointestinal (GI) infections result in 17 million cases annually, with foodborne illness costing the National Health Service (NHS) £60m per year. The burden of GI infection is unequally distributed, with greater impact in more socioeconomically disadvantaged groups and areas. Local authorities (LA) provide vital services that protect public health and wellbeing. The impact of funding cuts to local services and their effect on public health is an area of concern. Environmental health and regulatory (EH) services are responsible for roles such as food safety and infectious disease control. This study aims to understand the impact of local funding cuts on EH and GI infection outcomes. Methods: We will conduct an ecological longitudinal study in England from 2010-2019 at the LA level to examine how changes in EH expenditure overtime have impacted EH and GI infection outcomes. Data will be gathered on food hygiene enforcement, food hygiene compliance levels, GI infection hospitalisation, NHS 111 calls relating to GI infection symptoms, GI infection pathogen data, deprivation, and population density. Measures will be aggregated to LA level and statistical analysis will be carried out. Ethics and dissemination: University of Liverpool Ethics committee have confirmed ethical approval will not be required. All data will be aggregated and anonymised, therefore only data sharing agreements will be required. Findings will be disseminated to the stakeholder group in addition to outputs through conferences and publications. These findings will help understand impact of key services on public health and should inform government and public health policy and strategy.
