Summary
The introduction of intermediate care units (IMCs) did not increase hospital costs per patient. Higher costs were linked to patient factors like longer intensive care unit (ICU) stays and more complex interventions.
Area of Science:
- Healthcare Management
- Critical Care Medicine
- Health Economics
Background:
- High costs of critical care necessitate cost-reduction strategies.
- Intermediate care units (IMCs) are developed to manage lower-risk patients, aiming to reduce overall costs.
- This study evaluates the impact of introducing an IMC on hospital costs for intensive care patients.
Purpose of the Study:
- To compare total hospital costs for intensive care patients before and after the establishment of an IMC.
- To identify factors contributing to changes in hospital costs following IMC implementation.
Main Methods:
- A comparative longitudinal study design was employed.
- Data collected from a university hospital with an intensive care unit (ICU), IMC, and general wards.
- Total hospital costs were analyzed for ICU patients admitted pre- and post-IMC introduction.
Main Results:
- Mean total hospital cost per patient significantly increased post-IMC introduction (from n12,961 to n16,513).
- Multiple regression analysis indicated patient characteristics, not IMC introduction, explained the cost increase.
- Factors such as a higher proportion of surgical patients, increased therapeutic intervention requirements, and longer ICU stays were significant predictors of higher costs.
Conclusions:
- The observed increase in mean total hospital costs was primarily attributed to patient-related factors.
- Patients with high Therapeutic Intervention Scoring System (TISS) scores and longer ICU stays were associated with increased costs.
- The introduction of the IMC itself was not the direct cause of the overall cost escalation.

Hospitals provide inpatient and outpatient services. Inpatient services provide care to patients that stay in the hospital for an extended period, ranging from days to months. Examples of inpatient services include intensive care units, hospital wards, or surgeries. Outpatient services provide care to patients who come to a hospital for a diagnostic or treatment but do not stay overnight —for example, diagnostic tests, surgical procedures, or health education.

01:29Documentation in Long-Term and Home Healthcare Setting
Documentation in long-term care facilities and home healthcare settings is crucial for ensuring continuous, coordinated, and comprehensive care for patients. Each setting has its specific documentation processes and tools:

01:19Restorative Care
Restorative care is provided once a patient has been discharged from a healthcare facility and requires additional services. The additional services include home care, rehabilitation programs, and extended care. Restorative care centers help the patient regain their previous level of functioning or acquire a new level of functioning due to the incapacitating effects of a disease or a disability. It aims to assist patients in enhancing their quality of life by encouraging independence,...
01:21Tertiary Healthcare System
Specialized care provided over an extended period is called tertiary care. Usually, a primary or secondary care physician will refer a patient to tertiary care. A patient's maximum physical and mental function is restored in tertiary care, which is caused due to the impact of a chronic illness or condition. Tertiary care aims to achieve the highest level of functioning possible while managing chronic illness. For example, a patient who falls and fractures their hip will need secondary care to...
01:15Methods of Documentation VI: Case Management Model
The case management model is a multidisciplinary approach that involves healthcare professionals from diverse disciplines, such as physicians, nurses, therapists, social workers, and pharmacists, working collaboratively to address the various needs of patients. Each healthcare professional brings unique expertise and perspectives, contributing to a more comprehensive understanding of the patient's condition and tailoring treatment plans accordingly.

01:26Methods Of Healthcare Delivery System
At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is limited...
