Answer 1

Method getLastInsertId() return id of just saved records.
If you need this id in your view just after save, you must first set that variable in your controller like $this->set(compact('lastid','patient'); and then use in view <?php echo $lastid; ?>

Answer 2

use
if ($this->Patient->save($this->request->data)) {
$id = $this->Patient->id;
$patient=$this->Patient->find('all',array('conditions'=>array('Patient.id'=>$id),'recursive' => -1));
$this->set->('patient', $patient);
//If you are saving the record with ajax which it looks like you
//might be from your question you will need the following instead
//of $this->set->('patient', $patient); try:
return json_encode($patient);
You will then also need to update your js ajax call, you will have a json array to decode so parse it with jquery and append it back into your view.
Cake will always give you the id of record you have just saved, by simply adding $id = $this->MyModel->id; You can use the id to query for the record.

Answer 3

Try below code:
In controller:
$lastid=$this->Patient->getLastInsertId();
$this->set(compact('lastid','patient');
Then use $lastid in View file.
In controller:
$lastid=$this->Patient->getLastInsertId();
$patient['Patient']['last_id'] = $lastid;
then use $patient['Patient']['last_id'] in your view file.
