Compare the attributable health impacts between two scenarios

Source: R/compare.R
compare.Rd

This function calculates the health impacts between two scenarios (e.g. before and after a intervention in a health impact assessments) using either the delta or pif approach.

Usage

compare(
  output_attribute_scen_1,
  output_attribute_scen_2,
  approach_comparison = "delta"
)

Arguments

output_attribute_scen_1

Scenario 1 as in the output of attribute()

output_attribute_scen_2

Scenario 2 as in the output of attribute()

approach_comparison

String showing the method of comparison. Options: "delta" or "pif".

Value

This function returns a list containing:

1) health_main (tibble) containing the main results from the comparison;

  • impact (numeric column) difference in attributable health burden/impact between scenario 1 and 2

  • impact_scen_1 (numeric column) attributable health impact of scenario 1

  • impact_scen_2 (numeric column) attributable health impact of scenario 2

  • And many more

2) health_detailed (list) containing detailed (and interim) results from the comparison.

  • results_raw (tibble) containing comparison results for each combination of input uncertainty for both scenario 1 and 2

  • results_by_geo_id_micro (tibble) containing comparison results for each geographic unit under analysis (specified in geo_id_micro argument)

  • results_by_geo_id_macro (tibble) containing comparison results for each aggregated geographic unit under analysis (specified in geo_id_macro argument))

  • input_table (list) containing the inputs to each relevant argument for both scenario 1 and 2

  • input_args (list) containing all the argument inputs for both scenario 1 and 2 used in the background

  • scen_1 (tibble) containing results for scenario 1

  • scen_2 (tibble) containing results for scenario 2

Details

Function arguments

approach_comparison Please note that the PIF comparison approach assumes same baseline health data for scenario 1 and 2 (e.g. comparison of two scenarios at the same time point).

With the delta comparison approach, the difference between two scenarios is obtained by subtraction. The delta approach is suited for all comparison cases, and specifically for comparison of a situation now with a situation in the future.

Methodology

Information about the methodology (including corresponding equations and literature) is available in the package vignette. More specifically, see chapters:
