Education Curriculum Notes
Education Curriculum Outline
Introduction
This outline curriculum is intended for persons who are planning to either give or attend a course on wound infection. It is not a course in itself, but an outline of the aims and learning outcomes that we would expect to be achieved at different levels, as well as the type of materials that would be provided. Some slides are included, but we would expect any course to provide considerably more detail in terms of content and variety of materials.
Curricula outlines for the following modules are included:
| |Fundamental (main objective = to know)|Intermediate (main objectives = to |Advanced (main objectives = to |
| | |understand and apply) |analyse, synthesise and evaluate) |
|Microbiology |Microbiology Fundamental |Microbiology Intermediate |Microbiology Advanced |
|Assessment & Diagnosis |Assessment and diagnosis Fundamental |Assessment and diagnosis Intermediate |Assessment and diagnosis Advanced |
|Management & Evaluation|Management and Evaluation Fundamental |Management and Evaluation Intermediate|Management and Evaluation Advanced|
• The Fundamental level is for students and newly qualified clinician, HCAs, assistant practitioners (and may also be suitable for lay people)
• The Intermediate level is for interested clinicians and those new in specialist posts
• The Advanced level is for experienced specialist clinicians
However it is recognised that depending on their background or discipline, people may need to access different levels within each area, for example intermediate microbiology but advanced assessment and diagnosis.
The aims and objectives for each module within the outline curriculum are provided in each of the module explanations that are laid out below.
The slide sets attached within each module include key definitions, examples and diagrams. All additional appropriate materials within each module should be included. We also refer to essential reading within each module.
We anticipate that each module will be equivalent to 150 hours of study, providing opportunities for students to gain continuing professional educational points according to their respective national systems.
