Medical health officer reports
A medical health officer (MHO) at Interior Health is required by the Public Health Act to report on the health and wellness of people living, learning and working in British Columbia’s Southern Interior.
These reports celebrate our progress and shine a light on important population health issues that can be addressed through the organized efforts of the health-care system and its community partners.
Climate Change, Health and Well-being
Published April 2024
The Medical Health Officer (MHO) Report 2023 provides an overview of the health status of communities across the Interior Health (IH) region, as it relates to climate change. The report includes reflections on climate-related events and experiences of the previous few years and explores the climate hazards that are most likely to impact the region: extreme heat, cold, flooding, wildfire and smoke, and drought.
The report includes stories of innovation and resilience to climate change that are intended to inspire action and creative solutions at the community level. When efforts to reduce climate risks are coordinated across sectors, there are many social, economic, and cultural co-benefits that support individual and community health, as well as benefiting the health system and the environment.
The Toxic Drug Crisis in BC’s Interior Region Part 1
Published June 2022
Part 1 (MHO Report 2021) describes the population health impacts of the toxic drug supply, introduces many of the issues at play, and reports on the results of a chart review of people who died before the pandemic began. We highlight the many interventions advanced within the health-care system, highlighting some of the successes and challenges. We extend our heartfelt condolences to the individuals, families, friends and communities impacted by these preventable deaths.
The Toxic Drug Crisis in BC's Interior Region Part 2
Published August 2023
Part 2 (MHO Report 2022) updates on the recent impact of the toxic drug crisis, explores what we understand about the reasons people may use toxic drugs, and lays out a framework to understand all of the work needed in the response to this crisis. This report also explores some of the data related to the toxic drug crisis. These aren’t just statistics and numbers, however; these are people we know and love. They are people in our families, people we work with, our neighbours and our friends. We receive reports every month on the number of people who have lost their lives needlessly. This is extremely hard for families, communities and frontline workers as they face this challenge.
Alcohol and Health in B.C.'s Interior Region
Published: July 2021
Alcohol is arguably the most socially acceptable of psychoactive substances. In this report, we describe a public health approach that recognizes the social and economic benefits attributable to alcohol while preventing and mitigating the health and social harms. We reflect the perspectives of partners, and recommend collaborative action to improve care, reduce harm and address underlying health determinants.

This report, and its recommendations, are for all partners within IH and across the Interior region who can contribute their knowledge, skills and resources to this collective effort.

Drinking Water in Interior Health: An Assessment of Drinking Water Systems, Risks to Public Health, and Recommendations for Improvement
Published: January 2017
This report reviews the state of the drinking water systems in our region. It was made to support water system owners and operators. We hope water suppliers will use it to inform all users about the essential service they provide. We also hope it will encourage discussion with users and leaders on the value of clean, safe tap water and their community water system. Let’s work together to ensure that everyone has clean, safe drinking water.
