Access to Health Services


Goal

Improve access to comprehensive, quality health care services.


Overview

Access to comprehensive, quality health care services is important for the achievement of health equity and for increasing the quality of a healthy life for everyone. This topic area focuses on four components of access to care: coverage, services, timeliness, and workforce.

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:
  1. Gaining entry into the health care system.
  2. Accessing a health care location where needed services are provided.
  3. Finding a health care provider with whom the patient can communicate and trust.2
Access to health care impacts:
  • Overall physical, social, and mental health status
  • Prevention of disease and disability
  • Detection and treatment of health conditions
  • Quality of life
  • Preventable death
  • Life expectancy
Disparities in access to health services affect individuals and society. Limited access to health care impacts people's ability to reach their full potential, negatively affecting their quality of life. Barriers to services include:
  • Lack of availability
  • High cost
  • Lack of insurance coverage
These barriers to accessing health services lead to:
  • Unmet health needs
  • Delays in receiving appropriate care
  • Inability to get preventive services
  • Hospitalizations that could have been prevented 3

Understanding Access to Health Services

Access to health services encompasses four components: coverage, services, timeliness, and workforce.

Coverage

Health insurance coverage helps patients get into the health care system. Uninsured people are:
  • Less likely to receive medical care
  • More likely to die early
  • More likely to have poor health status
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. Current policy efforts focus on the provision of insurance coverage as the principal means of ensuring access to health care among the general population. Other factors, described below, may be equally important to removing barriers to access and utilization of services.

Services

Improving health care services depends in part on ensuring that people have a usual and ongoing source of care. People with a usual source of care have better health outcomes and fewer disparities and costs.
Having a primary care provider (PCP) 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.Having a usual PCP is associated with:
  • Greater patient trust in the provider
  • Good patient-provider communication
  • Increased likelihood that patients will receive appropriate care
Improving health care services includes increasing access to and use of evidence-based preventive services. Clinical preventive services are services that:
  • Prevent illness by detecting early warning signs or symptoms before they develop into a disease (primary prevention).
  • Detect a disease at an earlier, and often more treatable, stage (secondary prevention).15
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.16 Within the last several years, complex problems facing the emergency care system have emerged.17 Ensuring that all persons have access to rapidly responding, prehospital EMS is an important goal in improving the health of the population.

Timeliness

Timeliness is the health care system's ability to provide health care quickly after a need is recognized. Measures of timeliness include:
  • Time spent waiting in doctors' offices and emergency departments (EDs)
  • Time between identifying a need for specific tests and treatments and actually receiving those services
Actual and perceived difficulties or delays in getting care when patients are ill or injured likely reflect significant barriers to care. Prolonged ED wait time:
  • Decreases patient satisfaction.
  • Increases the number of patients who leave before being seen.
  • Is associated with clinically significant delays in care.
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, there is a decrease in the total number of EDs in the United States.
