Using {:,:} to convert the entire table to a homogeneous array is perhaps one way to do this, but scales badly very quickly as the table gets big.
allMissing = all(ismissing(patients),1)
gives you a logical vector of variables in the table all of whose values are missing (whether or not they are numeric). Use that as a subscript into patients.Properties.VariableNames.
