Trends in hospital coding for people experiencing homelessness in Canada, 2015-2020: a descriptive study.

BACKGROUND: In 2018, hospitals were mandated to record homelessness using International Statistical Classification of Diseases and Related Health Problems, 10th Revision, Canada (ICD-10-CA code Z59.0). We sought to answer whether the coding mandate affected the volume of patients identified as experiencing homelessness in acute inpatient hospitalizations and if there was any geographic variation. METHODS: We conducted a serial cross-sectional study describing 6 fiscal years (2015/16 to 2020/21) of hospital administrative data from the Hospital Morbidity Database. We reported frequencies and percentages of hospitalizations with a Z59.0 diagnostic code and disaggregated by several types of Canadian geographies. Controlling for fiscal quarter (coded Q1 to Q4) and province or territory, adjusted logistic regression models quantified the odds of Z59.0 being coded during hospital stays. RESULTS: The frequency and percentage of people experiencing homelessness in hospitalization records across Canada increased from 6934 (0.12%) in 2015/16 to 21 529 (0.41%) in 2020/21. Trends varied by province and territory. Recording of the Z59.0 code increased following the mandate (adjusted odds ratio 2.29, 95% confidence interval 2.25-2.32), relative to the pre-mandate period. INTERPRETATION: The 2018 coding mandate coincided with an increase in the use of the Z59.0 code to document homelessness in health care administrative data; however, trends varied by jurisdiction. The ICD-10-CA code Z59.0 presents a promising opportunity for standardized and routinely collected data to identify people experiencing homelessness in hospital administrative data.

The Canadian Alcohol Policy Evaluation project: Findings from a review of provincial and territorial alcohol policies.

INTRODUCTION: Effective alcohol control measures can prevent and reduce alcohol-related harms at the population level. This study aims to evaluate implementation of alcohol policies across 11 evidence-based domains in Canada's 13 jurisdictions. METHODS: The Canadian Alcohol Policy Evaluation project assessed all provinces and territories on 11 evidence-based domains weighted for scope and effectiveness. A scoring rubric was developed with policy and practice indicators and peer-reviewed by international experts. The 2017 data were collected from publicly-available regulatory documents, validated by government officials, and independently scored by team members. RESULTS: The average score for alcohol policy implementation across Canadian provinces and territories was 43.8%; Ontario had the highest (63.9%) and Northwest Territories the lowest (38.4%) jurisdictional scores. Only six of 11 policy domains had average scores above 50% with Monitoring and Reporting scoring the highest (62.8%) and Health and Safety Messaging the lowest (25.7%). A 2017 provincial/territorial current best practice score of 86.6% was calculated taking account of the highest scores for any individual policy indicators implemented in at least one jurisdiction across the country. DISCUSSION AND CONCLUSIONS: Most of the evidence-based alcohol policies assessed by the Canadian Alcohol Policy Evaluation project were not implemented across Canadian provinces and territories as of 2017, and many provinces showed declining scores since 2012. However, the majority of policies assessed have been implemented in at least one jurisdiction. Improved alcohol policies to reduce related harm are therefore achievable and could be implemented consistently across Canada.

Alcohol retail privatisation in Canadian provinces between 2012 and 2017. Is decision making oriented to harm reduction?

INTRODUCTION: Policy changes may contribute to increased alcohol-related risks to populations. These include privatisation of alcohol retailing, which influences density of alcohol outlets, location of outlets, hours of sale and prevention of alcohol sales to minors or intoxicated customers. Meta-analyses, reviews and original research indicate enhanced access to alcohol is associated with elevated risk of and actual harm. We assess the 10 Canadian provinces on two alcohol policy domains-type of alcohol control system and physical availability of alcohol-in order to track changes over time, and document shifting changes in alcohol policy. METHODS: Our information was based on government documents and websites, archival statistics and key informant interviews. Policy domains were selected and weighted for their degree of effectiveness and population reach based on systematic reviews and epidemiological evidence. Government representatives were asked to validate all the information for their jurisdiction. RESULTS: The province-specific reports based on the 2012 results showed that 9 of 10 provinces had mixed retail systems-a combination of government-run and privately owned alcohol outlets. Recommendations in each provincial report were to not increase privatisation. However, by 2017 the percentage of off-premise private outlets had increased in four of these nine provinces, with new private outlet systems introduced in several. DISCUSSION AND CONCLUSIONS: Decision-making protocols are oriented to commercial interests and perceived consumer convenience. If public health and safety considerations are not meaningfully included in decision-making protocols on alcohol policy, then it will be challenging to curtail or reduce harms.
