| Model | Dimension | Examples |
|---|---|---|
| Original Penchansky and Thomas model | Availability of health care resources | Resources (personnel, equipment, technology), prevailing wait times |
| Accessibility as it relates to geographic considerations | Centralized services, "close to home" care, transportation | |
| Accommodation in terms of how health care is organized and delivered | Coordination and integration of services, satellite cancer clinics, telemedicine | |
| Affordability as it relates to direct and indirect costs of receiving care | Funding of cancer services, insurance/drug coverage, indirect patient costs (lodging, transportation) | |
| Acceptability as it relates to the attitudes and characteristics of patients and providers | Patient and provider attitudes toward one another, patient characteristics (e.g., age, sex, comorbid conditions, life expectancy), patient preferences, provider characteristics (sex, years of practice, level of specialization, surgery volume) | |
| Added* | Awareness of services and indications for their use | Patient and provider awareness of evidence for therapy, clinical practice guidelines, structures that support multidisciplinary dialogue/consultation |
*More recently, MacKillop identified and described this additional important dimension of access.26
