CAOHC Program Evaluation and Effectiveness Metrics 2

Question 1

What does it mean when the program's STS rate decreases but workers report increasing difficulty hearing in the workplace?

Accepted Answer

Subjective communication difficulty may precede measurable threshold shifts, or workers may be experiencing suprathreshold processing problems not captured by pure-tone audiometry

Answer

The workers' reports are unreliable and should be disregarded

Answer

The STS rate is the only valid measure, so the program is effective

Answer

Workers are confused about what hearing difficulty means

Question 2

What is the value of benchmarking a hearing conservation program against NIOSH criteria for an 'effective' program?

Accepted Answer

NIOSH criteria provide evidence-based standards that identify specific areas where a program exceeds or falls short of best practice

Answer

NIOSH criteria are outdated and no longer relevant

Answer

Only OSHA compliance matters, not NIOSH recommendations

Answer

NIOSH criteria only apply to government workplaces

Question 3

How should the OHC use program evaluation data to prepare for the annual report to the supervising professional?

Accepted Answer

Compile key metrics, highlight trends, identify concerns, and propose specific recommendations for professional review

Answer

Submit raw data without analysis or interpretation

Answer

Wait for the professional to request specific information

Answer

The OHC does not prepare reports for the supervising professional

Question 4

What is the significance of tracking the 'false-positive STS rate' in program evaluation?

Accepted Answer

It indicates the proportion of detected STSs that resolve on retest, suggesting testing artifacts rather than true hearing loss

Answer

False-positive STSs are impossible in a properly calibrated program

Answer

A high false-positive rate is always desirable

Answer

False-positive rates cannot be calculated from routine audiometric data

Question 5

What comprehensive approach to program evaluation does CAOHC recommend for OHCs?

Accepted Answer

A multi-component evaluation addressing all program elements including monitoring, audiometry, protection, training, and recordkeeping

Answer

Evaluation of only the audiometric testing component

Answer

Evaluation based solely on OSHA compliance status

Answer

No specific evaluation approach is recommended by CAOHC

Question 6

How does evaluating the timeliness of follow-up actions after STS detection contribute to program quality?

Accepted Answer

Delayed follow-up allows continued unprotected exposure, so tracking response times ensures workers receive prompt protective intervention

Answer

Follow-up timing has no impact on outcomes

Answer

All follow-up actions should wait until the annual review

Answer

Only workers who request follow-up should receive it
