Several factors, including travel time, logistics, and case complexity, influence a case manager’s caseload capacity. For example, a case manager who conducts face-to-face case management in a rural area will maintain a smaller caseload than a telephonic case manager. And complex cases require more time and involvement than disease management cases. Other circumstances that affect caseload size include:
Operational factors
- Practice setting (e.g., clinic, hospital, subacute, health plan, workers’ compensation, field)
- Types of interactions (face-to-face, telephonic, hybrid)
- Technology, tools, and documentation methods (the number of steps or computer clicks to document or access information; the number of information technology systems used, such as electronic medical records, faxing, and data analysis software)
- Non-case management activities (meetings, continuing education, travel, training)
Professional factors
- Professional discipline (e.g., nursing, social work, physical therapy)
- Experience of case manager, length of time in current role
- Current workload and performance metrics
- Roles the case manager performs (behavioral health, utilization management, disease management, integrated services, supervisory roles, preceptor/trainer)
Population factors
- Case complexity and acuity
- Regulatory and legal requirements (e.g., Medicare/Medicaid regulations, accreditation)
- Availability of resources
- Cultural and linguistic needs
Specialty case managers (in behavioral health, maternity, or oncology, for example) may be able to manage a higher caseload than generalist case managers. Since similar clients require similar resources, education, and services, these case managers become more efficient over time and are capable of taking a higher caseload. Likewise, a CM assigned to a relatively small, contained geographic area may manage more cases than one covering multiple states or an entire time zone. A CM’s ability to meet metrics is another consideration. A case manager who does not meet the metrics for her current caseload should not be assigned additional cases.
Ultimately, the correct caseload size is one that allows the case manager to achieve the outcomes of the case management program, maintain quality standards, and ensure clients receive appropriate resources in a timely manner.
Successful caseload management also depends on appropriately matching the client and the CM. Case assignments are often made arbitrarily; for example, assigning a hospital CM to an entire unit or floor or a health plan CM to a contract or a specific time zone. Though that method is not wrong, other factors should be considered when possible:
- CM’s professional discipline (e.g., nursing, social work, physical therapy)
- CM’s state licensure
- CM’s previous work experience (OB, oncology, behavioral health)
- CM’s experience level, where highly experienced CMs are assigned the most complex cases
- CM and client cultural match (e.g., similar cultural backgrounds or language proficiency)
