Occupancy rate

A measure of inpatient health facility use, determined by dividing available bed days by patient days. It measures the average percentage of a hospital's beds occupied and may be institution-wide or specific for one department or service.

Occupational health

OSHA, county health departments and regulatory bodies oversee occupational health hazards in workplaces, including hospitals. Occupational health programs include the employer activities undertaken to protect and promote the health and safety of employees in the workplace, including minimizing exposure to hazardous substances, evaluating work practices and environments to reduce injury, and reducing or eliminating other health threats. Many health providers offer occupational health consultations as well as occupational health screenings, treatments and casemanagement. Employers and health providers often enter agreements whereby health providers will provide these services as well as managed the related workers compensation case management and rehabilitation programs. Employers seek to remain in compliance with regulations and reduce costs associated with employee injury and benefit utilization. Often, EAPs and drug prevention or drug testing programs are also combined under this category.

Office of Inspector General (OIG)

The office responsible for auditing, evaluating and criminal and civil investigating for HHS, as well as imposing sanctions, when necessary, against health care providers. (see also Fraud, FBI, Dept. of Justice)

Open Access

Health plan members' abilities, rights or invitation to self refer for specialty care. Also called Open Panel.

Open Enrollment Period

A period of time which eligible subscribers may elect to enroll in, or transfer between, available programs providing health care coverage. Under an open enrollment requirement, a plan must accept all who apply during a specific period each year.

Outcome

A clinical outcome is the result of medical or surgical intervention or nonintervention.  

Outcomes Management

Providers and payers alike wish to find a method of managing care in a way that would produce the best outcomes. Managed care organizations are increasingly interested in learning to manage the outcome of care rather than just managing the cost of care. It is thought that through a database of outcomes experience, caregivers will know better which treatment modalities result in consistently better outcomes for patients. Outcomes management may lead to the development of clinical protocols.

Outcomes Measurement

System used to track clinical treatment and responses to that treatment. The methods for measuring outcomes are quite varied among providers. Much disagreement exists regarding the best practice or tools to utilize to measure outcomes. In fact, much disagreement exists in the medical field about the definition of outcome itself.

Out of Network Benefits

With most HMOs, a patient cannot have any services reimbursed if provided by a hospital or doctor who is not in the network. With PPOs and other managed care organizations, there may exist a provision for reimbursement of "out of network" providers. Usually this will involve a higher copay or a lower reimbursement. See also point of service plans.

Out-of-Network Provider

A health care provider with whom a managed care organization does not have a contract to provide health care services. Because the beneficiary must pay either all of the costs of care from an out-of-network provider or their cost-sharing requirements are greatly increased, depending on the particular plan a beneficiary is in, out-of-network providers are generally not financially accessible to Medicaid beneficiaries.

Out of Pocket Expenses, Out of Pocket Costs

Portion of health services or health costs that must be paid for by the plan member, including deductibles, co-payments and co-insurance. In the age of managed care, out of pocket expenses can also refer to the payment of services not covered by or approved for reimbursement by the health plan.

Out of Pocket Limit

A cap placed on out of pocket costs, after which benefits increase to provide full coverage for the rest of the year.

Outpatient Care

Care given a person who is not bedridden. Also called ambulatory care. Many surgeries and treatments are now provided on an outpatient basis, while previously they had been considered reason for inpatient hospitalization. Some say this is the fastest growing segment of healthcare.
