Access to Health Services
Improve access to comprehensive, quality health care services.
Access to comprehensive, quality health care services is important for promoting and maintaining health, preventing and managing disease, reducing unnecessary disability and premature death, and achieving health equity for all Americans. This topic area focuses on 3 components of access to care: insurance coverage, health services, and timeliness of care. When considering access to health care, it is important to also include oral health care and obtaining necessary prescription drugs.
Why Is Access to Health Services Important?
Access to health services means "the timely use of personal health services to achieve the best health outcomes."1 It requires 3 distinct steps:
- Gaining entry into the health care system (usually through insurance coverage)
- Accessing a location where needed health care services are provided (geographic availability)
- Finding a health care provider whom the patient trusts and can communicate with (personal relationship)2
Access to health care impacts one's overall physical, social, and mental health status and quality of life.
Barriers to health services include:
- High cost of care
- Inadequate or no insurance coverage
- Lack of availability of services
- Lack of culturally competent care
These barriers to accessing health services lead to:
- Unmet health needs
- Delays in receiving appropriate care
- Inability to get preventive services
- Financial burdens
- Preventable hospitalizations
Access to care often varies based on race, ethnicity, socioeconomic status, age, sex, disability status, sexual orientation, gender identity, and residential location.3
Understanding Access to Health Services
The Access to Health Services topic area encompasses 3 components: coverage, services, and timeliness.
Health insurance coverage helps patients gain entry into the health care system. Lack of adequate coverage makes it difficult for people to get the health care they need and, when they do get care, burdens them with large medical bills. Uninsured people are:
- More likely to have poor health status
- Less likely to receive medical care
- More likely to be diagnosed later
- More likely to die prematurely4, 5, 6
Improving access to health care services depends in part on ensuring that people have a usual and ongoing source of care (that is, a provider or facility where one regularly receives care). People with a usual source of care have better health outcomes, fewer disparities, and lower costs.7, 8, 9, 10
Having a primary care provider (PCP) who serves as the usual source of care is especially important. PCPs can develop meaningful and sustained relationships with patients and provide integrated services while practicing in the context of family and community.11 Having a usual PCP is associated with:
- Greater patient trust in the provider
- Better patient-provider communication
- Increased likelihood that patients will receive appropriate care12,13
- Lower mortality from all causes14
- Prevent illness by promoting healthy behaviors in people without risk factors (e.g., diet and exercise counseling)
- Prevent illness by providing protection to those at risk (e.g., childhood vaccinations)
- Identify and treat people with no symptoms, but who have risk factors, before the clinical illness develops (e.g., screening for hypertension or colorectal cancer)
In addition to primary care and preventive services, emergency medical services (EMS) are a crucial link in the chain of care. EMS include basic and advanced life support.17 Notable progress has been made in recent years to ensure that everyone has access to rapidly responding EMS; it is an important effort in improving the health of the population.18
Timeliness is the health care system's ability to provide health care quickly after a need is recognized. Measures of timeliness include:
- Availability of appointments and care for illness or injury when it is needed
- Time spent waiting in doctors' offices and emergency departments (EDs)
The delay in time between identifying a need for a specific test or treatment and actually receiving those services can negatively impact health and costs of care. For example, delays in getting care can lead to:
- Increased emotional distress
- Increased complications
- Higher treatment costs
- Increased hospitalizations19
Actual and perceived difficulties or delays in getting care when patients are ill or injured likely reflect significant barriers to care.20 Prolonged ED wait time:
- Decreases patient satisfaction
- Increases the number of patients who leave before being seen
- Is associated with clinically significant delays in care21
Causes for increased ED wait times include an increase in the number of patients going to EDs, with much of the increase due to visits by less acutely ill patients. At the same time, the total number of EDs in the United States has decreased.22
Emerging Issues in Access to Health Services
Over the first half of this decade, as a result of the Patient Protection and Affordable Care Act of 2010, 20 million adults have gained health insurance coverage.23 Yet even as the number of uninsured has been significantly reduced, millions of Americans still lack coverage. In addition, data from the Healthy People Midcourse Review demonstrate that there are significant disparities in access to care by sex, age, race, ethnicity, education, and family income. These disparities exist with all levels of access to care, including health and dental insurance, having an ongoing source of care, and access to primary care. Disparities also exist by geography, as millions of Americans living in rural areas lack access to primary care services due to workforce shortages. Future efforts will need to focus on the deployment of a primary care workforce that is better geographically distributed and trained to provide culturally competent care to diverse populations.
Specific issues that should be monitored over the next decade include:
- Increasing and measuring insurance coverage and access to the entire care continuum (from clinical preventive services to oral health care to long-term and palliative care)
- Addressing disparities that affect access to health care (e.g., race, ethnicity, socioeconomic status, age, sex, disability status, sexual orientation, gender identity, and residential location)
- Assessing the capacity of the health care system to provide services for newly insured individuals
- Determining changes in health care workforce needs as new models for the delivery of primary care become more prevalent, such as the patient-centered medical home and team-based care
- Monitoring the increasing use of telehealth as an emerging method of delivering health care
