Sentinel Node Biopsy education module, provided by CancerQuest at Emory University. The module consists of an education video, information on the procedure in text, a self-quiz as well as external links to related resources.
Source: CancerQuest, an online resource that provides documented information about cancer for the public
Purpose: To provide a comprehensive overview of the SNB procedure in a multimedia format. Components include 3D animations, interview footage with doctors, detailed text on commonly asked questions, a self-test quiz and external links to related sites
Target audience: Patient/family
Strengths:
- Gives a complete picture of the SNB procedure; from the theory to practice and even post-procedural effects
- Gives the patient a sense of engagement by including interactivity
- Interview footage is useful to 'put a human face' on rationales and practices of the procedure
- 3D animation shows clearly the site of sentinel lymph nodes, and demonstrates how dye/radioactive material enters the lymphatics
Weaknesses:
- Self-test quiz is malfunctioning
- Not an 'introductory' module; patients may have difficulties understanding everything the first time
- Narrative/interviews still lack a sense of personal contact; both speak of 'the patient', not 'you'/'your'
- The analogy used in the video for the lymphatic vessels and lymph nodes ('small streams joining to form a river') seems misleading; lymph nodes are not merely a collection of lymph
- It would help to emphasize how cancerous cells migrate to other parts of the body via the lymphatic system
