Summary
This summary is machine-generated.Japanese medical corporations are consolidating facilities, with increasing horizontal and vertical integration. Despite fewer hospitals and beds, market concentration remains low, suggesting opportunities for optimized healthcare delivery.
Area Of Science
- Healthcare Management and Policy
- Health Services Research
- Health Economics
Background
- Medical corporations are pivotal in Japan's healthcare system, managing over half of all hospital beds.
- Previous analyses of hospital integration within these corporations have been limited.
- Understanding integration trends is crucial for optimizing healthcare delivery and resource allocation in Japan.
Purpose Of The Study
- To comprehensively analyze hospital integration trends among Japanese medical corporations.
- To assess changes in market concentration within the medical corporation sector.
- To provide data-driven insights for healthcare policy and resource management.
Main Methods
- A longitudinal study analyzing medical corporation financial data from 2017 to 2021.
- Evaluation of horizontal integration (multiple hospitals within one corporation) and vertical integration (hospitals with clinics/long-term care facilities).
- Calculation of the Herfindahl-Hirschman Index (HHI) to measure hospital market concentration using nationwide bed data.
Main Results
- A decrease in the total number of hospitals and hospital beds owned by medical corporations (2017-2021).
- A significant upward trend in both horizontal (24.92% to 55.75%) and vertical integration (26.92% to 59.42%).
- A slight increase in the mean HHI, indicating low market concentration overall, with higher concentration in rural areas.
Conclusions
- Japanese medical corporations show a declining number of facilities but increasing integration.
- Market dominance by any single corporation was not observed, indicating a competitive landscape.
- Findings support policy development for enhancing healthcare services and efficient resource distribution in Japan.

The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.

An integrated healthcare system (IHS) is a set of organizations that provides for or arranges to provide coordinated and continuous service to a defined population. The IHS takes responsibility for that particular population's health status and outcome, both clinically and fiscally. An integrated healthcare system is a well-organized, well-coordinated, and collaborative network. The integrated delivery system is a network that connects different healthcare providers to deliver organized,...
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...
Hospitals offer medical and surgical care to the sick and injured, along with accommodation while they recover. At the same time, they also provide outpatient, emergency, psychiatric, and rehabilitation services to meet various community needs. In addition to providing medical care, hospitals also act as hubs for medical research and training. Hospitals use clinical procedures and evidence-based practice standards to deliver patient care. To deliver safe and efficient care, a nurse must stay up...
Secondary healthcare is offered by a specialist, generally in hospitals or clinics for patients referred by primary healthcare providers. It occurs when a person has an illness or injury that requires specific medical care. Secondary care is often referred to as acute care. Secondary care can range from uncomplicated care to repair a minor laceration or treat a strep throat infection to more complicated emergent care, such as treating a head injury sustained in an automobile accident.

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.
