1.0 Provincial Heath Status Report Update (Ian Johnson)

Problems have arisen with geographic coding and the need for consistency across all the databases being used. Due to the amalgamation of municipalities in 1998, the MOH residence codes (MOHRCs) have changed substantially this year. Therefore, we had to develop a conversion file to convert pre-1998 MOHRCs to 1998 MOHRCs. For example, there is only one code for Toronto in the 1998 code book and it is different from any of the codes used for the former 6 municipalities. Hence the working group had to convert all of the data using the old codes for these 6 municipalities to the new 1998 code.

There are some older codes that require even more detailed work. For example, even after making the 1998 changes, many of the codes for areas such as Simcoe, had to be converted. Hyewon has been working with the Ministry and has provided the conversion for these codes. There is some concern that the PHS project is behind due to the geographic coding. However, the group agreed that it was important to get these codes correctly done and that it was a major infrastructure accomplishment.

2.0 Final Documentation of Health Indicators List

The title for the health indicators list must be decided upon; a working title is Core Population Health Indicators for Ontario.

Each indicator will stand alone in the report, even if it means repeating some information and increasing the volume of the final document. Preferably, one indicator per page.

Explicit criteria used to select the indicators should be included. Some of the criteria include: availability of data at the local level, accessibility, offering health relevant interpretation and usefulness as a tool for assessing needs for planning purposes.

Stress that the Mandatory Health Programs were an anchor in preparing the report and selecting the indicators.

3.0 Population (Julie Stratton)

It was that decided for each indicator, within the section labeled Data Sources, that the specific census year would not be specified unless changes in definition required that certain years not be compared.

Method of calculation for Aged dependency ratio is (total elderly over 65/total population aged 15 to 64)*100.

When using the 1991 Census, a note will explain differences in the way the immigrant population was determined from previous censuses. Julie will verify the changes.

In Comments, add the sentence "This census only identifies landed immigrants, not children of landed immigrants born in Canada."

In Comments, state "The proportion of immigrants provides an indication of the degree to which the population is foreign born independent of the fact how long they have been in Canada."

Within Data Sources, the numerator should read, "Census 1996 onward."

For Ethnicity, Home Language and Mother Tongue indicators, the top 15 languages in Ontario will be chosen, as used in the Provincial Report.

The exact question from the census will be included with two calculations

(Number of people in a single ethnic group (single response)/total respondents (single response))*100

(Total number of people in a given ethnic group (single response)+(multiple response)/total respondents for ethnicity)*100

The exact question from the census will be included with two calculations

(Number of people in a single mother tongue (single response)/total single respondents)*100.

English Mother Tongue: (Total number of people speaking English (single response)+(multiple response)/total respondents for mother tongue)*100, similarly for French Mother Tongue.

(Number of people in a single home language (single response) / total single respondents) * 100

English-speaking (Total number of people with English as their home language (single response) + (multiple response) / total respondents for home language)*100, similarly for French-speaking/Francophones.

In Method of Calculation, denominator should be Total non-institutional population.

4.0 Social Environment and Health (Hyewon Lee-Han)

Hyewon has purchased a special tabulation from Stats Canada for the Public Health Branch that will provide income by age group from the 1996 census, by census sub-division level.

Child Poverty and Senior Poverty indicators will stay within this section.

It has been verified with Stats Canada that the numerators, Number of households with gross rent spending 30% of more of household income on shelter cost and number of owned households with total average payments spending 30% of more of household income on shelter cost are considered to be classified under family household income. The denominators Total households in rental units and Total owned households are classified as a physical private dwelling. Hyewon will verify the definition of household income.

Indicator to be submitted by Hyewon

5.0 Environment and Health: Physical Environment (Vic Sahai)

This section to be discussed at the next PHIWG meeting

6.0 Mortality (Patrick Seliske)

Method of calculation: denominator should be Total Population instead of Total non-institutional population.

Appendix should include examples of direct and indirect methods of standardization. Although it is difficult to recommend grouping of years, a suggested guideline is that small numbers should be grouped around census years with confidence intervals included (i.e for the 1991 census, group years 1989-1993).

Potential Years of Life Lost (PYLL) calculations should also be included in an appendix.

Next Meetings, later re-scheduled to be:
Thursday, October 1 & Friday, October 2, 1998
