Health care professionals do not all receive the same emoluments. In all countries doctors are paid the most. They carry the greatest responsibility for making decisions that affect people and they are the most likely to be sued – so their differential pay seems fair. But the other side of the coin is that non-doctor health professionals can do many things equally well, or perhaps better. Similarly, there are things that Community Health Workers can do as well or better than nurses, and again at lower unit cost. There are many types of skill mix initiative, and the most widely used classification emanated from Bonnie Sibbald, herself a previous CLAHRC director:
Sibbald’s Skill-Mix Classification
- Extending roles
- Substituting – exchanging one type of worker for another
- Innovation – creating new jobs
Changing structures at the interface between services
- Transferring service from one setting to another
There are a number of systematic reviews on skill-mix summarising a great many articles. However, review authors agree that there is little clear evidence on effectiveness or cost-effectiveness. Many studies concentrate on skill substitution, usually comparing doctors and nurses. However, the subject is hard to study, and deriving generalisable conclusions is always going to be difficult because of differences in context – especially training. One cadre that has received a lot of attention over the last two decades involves innovation more than substitution – the use of Community Health Workers. They have a valuable role in prevention (e.g. malnutrition/vaccination), maintenance of therapy (e.g. HIV, TB and hypertension), and frontline care (e.g. rehydration therapy), as discussed in previous News Blogs.[3-5]
