- provides a space devoted to the conceptual framework known as Hodges' model. Read about this tool that can help integrate HEALTH, SOCIAL CARE, INFORMATICS and EDUCATION. The model can facilitate PERSON-CENTREDNESS, CURRICULUM DEVELOPMENT, HOLISTIC CARE and REFLECTION. Follow the development of a new website using Drupal (it might happen one day!!).

Hodges' model: Combined Care Feature Capture - Black Box + White Box?

Nursing is, in theory and practice, far removed from multimedia; which in turn has changed markedly from when the poster quoted below was published in 1999. 

Nursing is 'multi-media' in the sense of combining several data sources across several domains of knowledge and from a range of media.

The following is from a poster at: http://www9.org/final-posters/43/poster43.html
"Feature Detectors 
Feature detectors are used to build a semantically rich index entry for the original multimedia object. They do this on two different levels:
  1. Blackbox detectors are implemented in a programming language to access the raw multimedia data and to derive the desired features from it. Example: the web_header detector sends a HTTP HEAD request to the specified HTTP server and extracts the content type from the response.
  2. Whitebox detectors consist of queries over the already collected feature values. Example: the page_type detector uses the content type to determine if an object is a page.
In the general case blackbox detectors will derive low-level feature data, e.g., the color distribution of an image. But they can also be used for more complex tasks, like finding a face in an image. The function of whitebox detectors is to relate low-level features to concepts, e.g., an image is a portrait because its color distribution classifies it as a photo and it contains exactly one face."
Hodges' model is situated and in healthcare context is everything. Behind a hospital clinic or ward door we might expect certain features to be found. Out in the community following a referral again certain features will be found. The features take on a personalised nature as key features confirming a diagnosis, problem or care issue are presented by the patient (client) or their carer. I'm not sure whether this is useful or not, but the domains of Hodges' model suggests quite a few boxes are required to tick the box that is holistic - integrated care.

And that does not take account of exactly where the knowledge resides; that is another test.
