Quality Control & Process Improvement Flashcards

Which concept describes the process of identifying the single most significant cause of a problem using iterative questioning?

Answer: 5 Whys technique

The 5 Whys technique repeatedly asks 'why' to drill down from a symptom to its fundamental root cause, guiding effective corrective action.

A Pareto chart in orthotic quality improvement is MOST useful for:

Answer: Identifying which defect categories account for the majority of quality problems

A Pareto chart ranks defect types by frequency, highlighting the vital few causes—typically ~20% of causes producing ~80% of problems—to prioritize improvement efforts.

In the context of orthotic quality management, 'traceability' refers to:

Answer: The capacity to trace a device back to its manufacturer lot, materials, and fitting practitioner

Traceability links each dispensed device to its source lot, components, and the practitioner who fitted it, which is critical for recalls and outcome analysis.

Which approach is MOST consistent with a 'lean' quality improvement philosophy in an orthotic clinic?

Answer: Eliminating steps in the fitting process that add no value for the patient

Lean philosophy targets waste elimination—removing non-value-added steps—to streamline processes while maintaining or improving quality.

When performing a quality audit of orthotic fitting records, which finding is MOST concerning?

Answer: Missing documentation of the medical necessity evaluation for devices dispensed

Missing medical necessity documentation is a significant compliance and quality failure that can result in claim denial, audit liability, and inadequate patient care records.

A quality improvement team determines that 40% of patient complaints relate to long wait times for device delivery. Which improvement strategy is MOST appropriate?

Answer: Map and streamline the ordering and delivery workflow to reduce lead time

Workflow mapping (value stream mapping) identifies bottlenecks in the ordering and delivery process, enabling targeted improvements to reduce lead time.

Which practice BEST supports ongoing quality improvement in an orthotic clinic's staff competency?

Answer: Implementing regular observed skills assessments with documented feedback and remediation plans

Observed skills assessments with documented feedback and structured remediation ensure that competency gaps are identified and addressed systematically.
