Which item is NOT included in aspects of the service affecting access to health services?

The aspect of access to health services that is not typically influenced by the characteristics of a service is age. While age can certainly affect a person's health needs and the types of services they may require, it does not specifically refer to the operational components of the health service itself that affect how individuals can access those services.

In contrast, location is critical as it determines the physical distance individuals must travel to receive health care, which can significantly impact their ability to access services. Confidentiality relates to the privacy protections in place for patients and can influence their willingness to seek care, thereby affecting access. Staffing is important as the number and qualifications of health professionals available can directly affect service availability and patients' experiences within the healthcare system. Thus, age stands out as the factor not directly aligned with the aspects of service affecting access.
