CIEE Cost-Benefit Analysis of Interventions 2

Question 1

When calculating indirect costs of a workplace musculoskeletal injury, which of the following is typically included?

Accepted Answer

Lost productivity from coworkers distracted by the incident

Answer

Indirect costs include lost productivity from distracted coworkers, administrative time, and other hidden expenses beyond direct medical costs.

Question 2

The 'iceberg model' of injury costs suggests that for every $1 in direct costs, indirect costs typically amount to:

Accepted Answer

$1.10–$4.50

Answer

Research consistently shows indirect costs are approximately 1.1 to 4.5 times greater than direct costs, representing the hidden portion of the iceberg.

Question 3

A company is evaluating two ergonomic interventions: Intervention A costs $10,000 with a projected 3-year benefit of $40,000, and Intervention B costs $25,000 with a projected 3-year benefit of $80,000. Which metric best differentiates them for selection?

Accepted Answer

Benefit-cost ratio

Answer

Benefit-cost ratio (4.0 vs. 3.2) normalizes for investment size and allows direct comparison of efficiency across interventions.

Question 4

Which of the following scenarios best represents a 'hard savings' benefit in ergonomic CBA?

Accepted Answer

Reduction in annual workers' compensation claim payouts

Answer

Hard savings are quantifiable, direct financial reductions such as lower workers' compensation payouts that appear directly in financial statements.

Question 5

When conducting a pre/post analysis of an ergonomic intervention, the most critical methodological consideration is:

Accepted Answer

Controlling for confounding variables such as seasonal workload changes

Answer

Controlling for confounders like seasonal variation, staffing changes, or production shifts ensures the observed benefits are attributable to the ergonomic intervention.
