4.1 Types of Cancer Registries, Their Functions & Registry Operating Protocols

Why registry type matters

Many exam questions hinge on who is collecting the data and why. A question about follow-up rates, Class of Case or cancer conferences is set in a facility registry. A question about incidence, death clearance or deduplication across hospitals is set in a central registry. The purpose of the registry decides which cases it includes, which standards it follows and how its data are used.

The three registry types

Central registry functions in more detail

Central registries receive multiple reports for the same tumor from hospitals, pathology laboratories, physician offices, radiation centers and other states. They must:

1. Link records that belong to the same person using deterministic (exact-match) and probabilistic (weighted, likelihood-based) matching on name, date of birth, SSN, sex and address.
2. Consolidate the reports into one record per tumor, choosing the best value for each item. The NCRA Code of Ethics recognizes that consolidation may change inaccurate or incomplete submitted data.
3. Conduct death clearance by matching against state death certificates, then follow back to facilities and physicians for unmatched cancer deaths.
4. Share data with other states through interstate data exchange agreements, so residents diagnosed across state lines are counted in their home state.
5. Submit to NPCR and/or SEER and to NAACCR for certification and national statistics.

How a hospital registry is organized

A hospital registry usually sits in Health Information Management, the cancer service line, or quality management. Wherever it sits, it answers to two lines of authority:

• Administrative: a department director or administrator handles budget, staffing, space and performance evaluations.
• Programmatic (CoC-accredited programs): the cancer committee directs the program, approves protocols and reviews registry quality control results (Standards 2.1 and 6.1).

A registry staff typically includes ODS abstractors, casefinding and follow-up staff, and a registry manager. CoC requires an ODS on the cancer committee, and an ODS may serve as the Cancer Conference Coordinator and/or the Cancer Registry Quality Coordinator.

Written protocols and procedure manuals

The CoC glossary lists "policy and procedure" as retired terminology and replaces it with protocol: "a structured and consistent process crafted by the cancer program to help implement the required compliance criteria for specific CoC standards." All protocols must be approved by the cancer committee. Examples include the multidisciplinary cancer case conference protocol (Standard 2.5) and the cancer registry quality control protocol (Standard 6.1).

Beyond what CoC requires, NCRA's role delineation study lists "Maintain up-to-date policies and procedures" as a registry task. A well-run registry keeps a procedure manual that documents:

• The reference date and the case eligibility rules in use (CoC-required, state-required and reportable-by-agreement cases).
• Casefinding sources, how often each is screened, and how the suspense file is managed.
• Accession and sequence number conventions, abstracting workflow, and the current versions of reference manuals.
• Follow-up methods and schedules.
• Quality control methods, including who reviews what and how errors are corrected.
• Confidentiality and data release, including the approval route for internal and external data requests.
• Data security, backup and retention.

Update the manual whenever standards change. New STORE, Solid Tumor Rules and staging releases arrive at least once a year.

Budgeting basics

• Operating expenses (OPEX) recur every year: salaries and benefits, software licenses and maintenance, reference subscriptions, NCRA dues, and continuing education and travel. Budget CE time so each ODS can earn the 20 CE credits per two-year cycle (including 4 Category A credits and, over four years, 8 in-person CEIP credits) that the credential requires.
• Capital expenses (CAPEX) are large, long-lived purchases depreciated over several years, such as servers or a major registry software replacement.
• Showing the value of the registry to administrators means pointing to accreditation, benchmarking, community needs assessment, clinical trial screening and service-line planning.

Contracting for abstracting services

When a backlog or vacancy leads a hospital to use a contract abstracting service:

1. Apply CoC Standard 4.3 exactly as for employees. Abstracting is done by an ODS, or by a non-ODS working under the program's documented ODS supervision plan within the three-year credentialing window. Standard 4.3 explicitly covers contract and registry-service-company staff.
2. Execute a Business Associate Agreement under 45 CFR 164.502(e) and 164.504(e) before any access to protected health information.
3. Write measurable service levels into the contract: turnaround time, expected volume, the accuracy threshold on re-abstracting review, correction of errors at no charge, and secure remote access (for example, virtual desktop access with no local storage).
4. Keep quality control in-house. Contract cases are included in the program's Standard 6.1 quality control review, and an ODS may not review their own cases.

Exam traps

• Don't answer "policy and procedure manual annual approval required by CoC." The 2020 standards talk about protocols approved by the cancer committee, tied to specific standards.
• A central registry is not "just a bigger hospital registry." Its denominator is a population, and it must deduplicate and consolidate reports from many sources.
• Contract staff follow the same credential rule as employees. Outsourcing does not bypass CoC Standard 4.3.
