Infant and preschool immunization delivery in Alberta and Ontario: a partial cost-minimization analysis
Insights
Public health nurses in Alberta provide preschool immunizations more affordably than private physicians in Ontario. Both provinces achieved similar success in preventing diphtheria, tetanus, and polio, but disease rates varied for other illnesses.
Area of Science:
- Public Health
- Health Economics
- Epidemiology
Background:
- Preschool immunization delivery models differ between Alberta (public health nurses) and Ontario (private physicians).
- Understanding the cost-effectiveness and disease prevention success of different immunization delivery systems is crucial for public health policy.
Purpose of the Study:
- To conduct a partial cost-minimization analysis of preschool immunization delivery in Alberta and Ontario.
- To compare the effectiveness of immunization programs in preventing specific vaccine-preventable diseases in young children.
Main Methods:
- Cost-minimization analysis comparing labor costs in 1986 constant dollars.
- Comparative analysis of disease incidence rates (diphtheria, tetanus, poliomyelitis, pertussis, rubella, measles, mumps) between Alberta and Ontario from 1980 to 1986.
- Focus on the zero to four years age group.
Main Results:
- Labor costs for immunization delivery were 2.9 times higher in Ontario than in Alberta.
- Both provinces demonstrated equal success in preventing diphtheria, tetanus, and poliomyelitis.
- Disease-specific rates varied: Ontario had higher pertussis and initial measles rates, while Alberta had higher rubella, later measles, and mumps rates.
Conclusions:
- The public health nurse-led immunization delivery model in Alberta appears more cost-effective than the private physician model in Ontario.
- The study highlights the need for standardized, detailed age-specific disease incidence data for more definitive comparative analyses.
- Findings support the cost-efficiency of public health nurse-based immunization programs.
Abstract:
This paper is a partial cost-minimization analysis of preschool immunization delivery in Alberta and Ontario. Public health nurses deliver such immunization in Alberta while in Ontario it is usually provided by private physicians. In constant 1986 dollars, labour costs were 2.9 times higher in Ontario than in Alberta. Alberta and Ontario achieved equal success in preventing diphtheria, tetanus and poliomyelitis in the target population of zero to four years of age. Ontario's pertussis rates were higher than Alberta's from 1980 to 1986 inclusive (p less than 0.01). Rubella rates were higher in Alberta from 1980 to 1986 inclusive (p less than 0.05) but the congenital rubella rates for the same period were not. During 1980, Ontario's measles rate was higher (p less than 0.01) while for 1982 and 1986, Alberta's measles rates were higher. In 1986, Alberta's mumps rate was higher than Ontario's (p less than 0.01). The findings argue in favour of the less costly public health nurse approach to immunization delivery. A more definitive conclusion could have been reached had the provinces maintained more detailed age-specific disease incidence data.
