Summary
Simulated client surveys using real children safely evaluate health worker performance, revealing conspicuous observation biases, especially after quality improvement interventions.
Area of Science:
- Health Services Research
- Global Health
- Quality Improvement
Background:
- The simulated client (SC) method offers more realistic health worker performance data than conspicuous observation (CO).
- Previous SC studies lacked real children, limiting pediatric performance evaluation.
- This study explored using real children as SCs for pediatric illness evaluations.
Purpose of the Study:
- To assess the feasibility and safety of using real children as simulated clients.
- To compare performance data from SC surveys versus CO surveys.
- To evaluate the validity of CO by comparing it with SC findings.
Main Methods:
- Conducted simultaneous SC and CO surveys in 55 health facilities.
- Utilized adult caretakers as surveyors with real children.
- Compared 27 performance indicators using logistic regression.
Main Results:
- No serious issues arose during the SC survey with real children.
- CO showed moderately higher performance levels (16.4 pp difference).
- Bias was significantly greater for IMCI-trained workers (29.7 pp difference) than non-IMCI workers (3.1 pp difference).
Conclusions:
- SC surveys with real children are feasible and safe with precautions.
- CO introduces significant positive performance bias.
- Quality improvement interventions may amplify CO biases.
