I don't know JQuery, but I'm pretty sure the element you're calling load() on
(id='nhs_no') is the element you want the contents replaced. Not the element
you're validating.
Not to add too much to your plate, but you'll also need to use a browser that
has decent debugging tools. I prefer firefox, but some people pay for visual
studio and use IE.
With Firefox, my Ajax debugging goes something like this:
If it's not doing anything, then open up the Tools -> Javascript Console, clear
it out, refresh my page and see what JS or CSS errors my page has. If that
doesn't show anything, then open up the LiveHTTPHeaders FF plugin, try the
action that will use Ajax and watch the headers go back and forth to the server
to see what is getting passed.

I'll preface this by saying I don't use JQuery, but I would think your code
needs to be something like this:
<script type="text/javascript" src="/jquery.js"></script>
<script type="text/javascript">
<!--
function validate_nhsno(myInput) {
$('#nhs_no_msg').load(
'check_nhsno.cgi',
{
rm : 'validate_nhsno',
itemToValidate : myInput.value
});
}
// -->
</script>
HTML form contains:
NHS No: <input type="text" name="nhs_no" id="nhs_no"
onblur="validate_nhsno(this); return true;" />
<span id="nhs_no_msg"></span>
