I'm confused what the NextOfKinPerID refers to based on this query. can you explain what it is? maybe suggest a better column name?

SELECT *
FROM Patient AS pat
INNER JOIN Person AS p on pat.PersonID = p.PersonID
LEFT OUTER JOIN NextOfKin AS nok ON p.PersonID = nok.PersonID
LEFT OUTER JOIN Person AS nokp ON nok.NextOfKinPerID = nokp.PersonID
