Before the patient was sent to endocrine surgeons, how much did they spend in labs?

Amountr of patients who were requested 5 studies from the guidelines before being sent to Specialist.

Final Questions

1. What were the top 3 most common unnecessary referring lab/imaging items that contributed to total mean cost or the median cost (eg. $509.5)?

Non-Guidelines Studies
Plasma cortisol 147
Plasma Catecholamines 127
Urine Metanephrines 33
Urine cortisol 25
ACTH 23
Urine Catecholamines 23
MRI Abd W and W/O 19
CT A/P contrast 16
DHES1 Sulfate 16
CT A/P non-contrast 15
PET/CT 11
MRI Abd W/O 9
Ultrasound 8
CT adrenal protocol 5
Urine VMA 5
Chromogranin A 5
17-OH Progesterone 5
Testosterone Total 4
Urine Aldoster 3
Salivary cortisol 3
Estradiol 3
CT chest W/ and W/O contrast 2
CT Chest Non-contrast 2
Androstenedione 2
5-HIAA 2
Estrogen Total 2
FSH and LH 1
Prolactin 1
CT Chest contrast 0
MRI Abd W/contrast 0

2. Overall, how many studies (quantity of labs/imaging) were part of the guidelines from that total mean cost or median cost? is there a range in quantity? (i.e. 1, 1 to 2, 2, 2 to 3, 3 or more/other)

3. We previously discussed that delay for referral to ES may increase cost. But, I think we found no difference. Can you please confirm? Then, the question for example would be: is there an impact on cost for patients referred at 1 month (or 2 weeks, etc.) after incidental finding compared to someone that had a longer time until seen the ES? The variable for this is: Months - incidentaloma finding to ES.
