Quiz: Provider Organizations, Networks, and Scheduling

Test your understanding of provider organizations, networks, and scheduling with these review questions.

1. Why is a Referral modeled as its own node rather than as a simple edge between two providers?

  1. Because it never carries any properties beyond a date
  2. Because a referral carries enough independent data, such as referral_date, reason_code, status, and urgency, that reducing it to a single edge would lose information
  3. Because referrals cannot connect to a Patient node
  4. Because Referral Inference requires a property instead of a node
Show Answer

The correct answer is B. A Referral carries enough independent data, including its date, reason code, status, and urgency, that a health system genuinely needs to track, which is why it is modeled as its own node rather than a plain edge. Option A understates the amount of data a referral actually carries. Option C is false since a Referral node connects to the patient through a FOR_PATIENT edge. Option D confuses referral modeling with an unrelated inference technique.

2. What distinguishes a Medical License from a Board Certification?

  1. A Medical License is voluntary, while Board Certification is legally mandatory
  2. Both are identical credentials issued by the exact same governing body
  3. A Medical License is a state-issued legal authorization to practice medicine, while Board Certification is a voluntary, specialty-specific credential attesting to advanced competency beyond licensure
  4. A Medical License only applies to specialists, while Board Certification only applies to primary care providers
Show Answer

The correct answer is C. A Medical License is the state-issued legal authorization required to practice medicine, while a Board Certification is a voluntary credential from a specialty board attesting to advanced competency beyond the minimum required for licensure. Option A reverses which credential is mandatory versus voluntary. Option B incorrectly claims a shared issuing body. Option D fabricates a restriction to specific provider types that does not exist.

Concept Tested: Board Certification

3. What is Provider Capacity?

  1. The number of patients currently attributed to a PCP's panel
  2. The measured performance score of a provider across quality dimensions
  3. An explicit clinical order directing a patient to another provider
  4. The maximum patient volume a provider's schedule can absorb in a given period, given slot length, hours worked, and no-show rates
Show Answer

The correct answer is D. Provider Capacity is the ceiling on patient volume a schedule can absorb, computed from slot length, hours worked, and expected no-show rates. Option A describes panel size, a related but distinct concept tied to attribution. Option B describes Provider Rating. Option C describes a Referral.

4. Why does a health system model network membership as an IN_NETWORK edge rather than as a property on the Provider node?

  1. Because a provider can belong to more than one network simultaneously, and an edge can be repeated once per network while a property can only cleanly hold one value
  2. Because properties cannot carry an effective_date value
  3. Because only Facility nodes, never Provider nodes, can join a network
  4. Because edges are always faster to query than properties regardless of context
Show Answer

The correct answer is A. Since a provider can belong to more than one network at once, membership needs to be an edge that can repeat once per network, rather than a property that can only cleanly hold a single value. Option B fabricates a limitation on properties that does not exist. Option C contradicts the chapter's explicit inclusion of Provider nodes as network members. Option D makes an unsupported general performance claim.

Concept Tested: Provider Network

5. Why does the graph distinguish an OPERATES edge from an AFFILIATED_WITH edge between a hospital and a clinic?

  1. Because OPERATES and AFFILIATED_WITH are simply two names for the identical ownership relationship
  2. Because OPERATES reflects direct ownership while AFFILIATED_WITH reflects a looser partnership, a distinction that matters for referral leakage analysis and capital investment decisions
  3. Because AFFILIATED_WITH can only apply between two hospital departments
  4. Because OPERATES can only apply to outpatient facilities, never to emergency departments
Show Answer

The correct answer is B. OPERATES reflects direct ownership, while AFFILIATED_WITH reflects a looser partnership, and losing that distinction would mislead both referral leakage analysis and decisions about where capital investment can be directed without separate corporate approval. Option A contradicts the chapter's explicit contrast between the two edge types. Option C and D fabricate restrictions not present in the chapter.

6. Why does modeling the ED-to-inpatient pathway as a chain of nodes, such as triage, admit decision, and unit assignment, matter more than storing a single flat encounter_type field?

  1. Because a flat field is structurally incapable of storing an encounter_type value
  2. Because chaining nodes eliminates the need for an Emergency Severity Index property
  3. Because it lets a query trace timestamps and properties like boarding_time_hours across the pathway to answer questions such as which ESI-2 patients boarded longer than three hours, as a single traversal
  4. Because Inpatient Care can only be modeled after Emergency Department records are deleted
Show Answer

The correct answer is C. Chaining triage, admit decision, and unit assignment as separate nodes with their own timestamps and properties lets a single graph query trace exactly which ESI-2 patients boarded longer than three hours and identify the responsible department, which a flat field could never answer. Option A misstates what a flat field can store. Option B incorrectly claims the ESI property becomes unnecessary. Option D fabricates a destructive dependency that does not exist.

7. Dr. Okafor sends 120 referrals in a quarter, and a graph query finds that only 96 of them land on an in-network specialist. What is the leakage rate for that quarter?

  1. 4%
  2. 96%
  3. 80%
  4. 20%
Show Answer

The correct answer is D. Leakage is the share of referrals that go out of network: (120 − 96) / 120 = 24/120 = 20%. Option A incorrectly divides the wrong numbers. Option B reports the in-network percentage rather than the leakage rate. Option C reports the in-network share expressed differently, still not the leakage percentage.

Concept Tested: Referral

8. A patient sees both a PCP and a specialist within a 45-day window with no explicit referral order on file, and the specialist visit's diagnosis code plausibly follows from the PCP visit's diagnosis. What is this technique for flagging a candidate referral relationship called?

  1. Referral Inference
  2. Provider Capacity calculation
  3. Board Certification renewal
  4. Network adequacy verification
Show Answer

The correct answer is A. Referral Inference flags a candidate referral from a co-occurrence pattern, such as the same patient seeing both providers within a 30- to 60-day window with a plausible diagnosis progression, in the absence of an explicit referral order. Option B, C, and D each name an unrelated concept from elsewhere in the chapter that has nothing to do with inferring referral relationships from co-occurrence.

9. A cardiologist's schedule offers 128 theoretical weekly slots, trimmed to 115 realistically fillable slots after accounting for no-shows, and 113 of those slots are already booked. What is the resulting utilization rate, rounded to the nearest whole percent?

  1. 88%
  2. 98%
  3. 113%
  4. 65%
Show Answer

The correct answer is B. Utilization rate is booked slots divided by realistic capacity: 113 / 115 ≈ 0.98, or 98%. Option A incorrectly divides against the theoretical 128 slots instead of the realistic 115. Option C incorrectly treats booked slots as exceeding capacity. Option D applies an unrelated calculation that does not match either number given.

Concept Tested: Provider Capacity

10. Why does the chapter argue that a raw Provider Rating quality score cannot be compared meaningfully across two providers without also considering Provider Specialization?

  1. Because Provider Rating scores are recalculated every time a referral is inferred
  2. Because Provider Specialization is stored only as an edge, while Provider Rating can only ever be a node
  3. Because a raw quality score means little without knowing which patient population and procedure mix produced it, so comparing a primary care panel's score directly against a transplant surgeon's would be misleading
  4. Because only specialists are permitted to have a Provider Rating at all
Show Answer

The correct answer is C. A quality score depends heavily on the complexity of the patient population and procedure mix behind it, so comparing scores across very different specializations without that context invites a misleading apples-to-oranges comparison. Option A fabricates an unrelated recalculation trigger. Option B invents a storage restriction not described in the chapter. Option D contradicts the chapter's own PCP rating example.
