    Abstract Context: Pheochromocytomas and paragangliomas (PPGL) are rare causes of secondary hypertension, but when unrecognized, they can lead to serious complications. Data regarding PPGL screening are lacking.
    Objective: This study aimed to assess the rates and patterns of PPGL screening among eligible patients.
    Methods: We conducted a retrospective review of adults with hypertension seen in outpatient clinics of a large academic center between January 1, 2017, and June 30, 2020. We included patients with treatment-resistant hypertension, hypertension at age < 35 years, and/or adrenal mass(es).
    Results: Of 203 535 patients with hypertension identified, 71 088 (35%) met ≥ 1 inclusion criteria, and 2013 (2.83%) were screened for PPGL. Patients screened were younger (56.2 ± 17.4 vs 64.0 ± 17.1 years), more often women (54.1% vs 44.2%), and never-smokers (54.6% vs 47.5%, P < 0.001 for all). The rate of screening was highest in patients with hypertension and adrenal mass(es) (51.7%, vs 3.9% in patients with early-onset hypertension, and 2.4% in those with treatment-resistant hypertension). Multivariable logistic regression showed higher odds ratio (OR) of PPGL screening in women (OR [95% CI]: 1.48 [1.34-1.63]); Black vs White patients (1.35 [1.19-1.53]); patients with adrenal mass(es) (55.1 [44.53-68.15]), stroke (1.34 [1.16-1.54]), dyslipidemia (1.41 [1.26-1.58]), chronic kidney disease (1.40 [1.26-1.56]), and obstructive sleep apnea (1.96 [1.76-2.19]).
    Conclusion: PPGL screening is pursued in roughly half of patients with adrenal nodules and hypertension, but rarely in patients with treatment-resistant or early-onset hypertension. Similar to screening for other forms of secondary hypertension, PPGL screening occurs more often after serious complications develop.

    Abstract Background Primary aldosteronism (PA) is a common but under-recognized cause of secondary hypertension. Data directly comparing screening rates across single and overlapping indications are lacking. Methods and Results We conducted a retrospective review of adults with hypertension seen in outpatient clinics at a tertiary referral academic center between January 1, 2017, and June 30, 2020. We included patients with hypertension plus at least one of the following: resistant hypertension; age<35 years; obstructive sleep apnea; hypokalemia; or an adrenal mass. We excluded patients with adrenal insufficiency, severe renal disease, or heart failure, and renovascular hypertension. Of 203 535 patients with hypertension, 86044 (42.3%) met at least 1 PA screening criterion, and of these, 2898 (3.4%) were screened for PA. Screening occurred in 2.7% of patients with resistant hypertension; 4.2% of those with obstructive sleep apnea; 5.1% of those <35 years; 10.0% of those with hypokalemia; and 47.3% of patients with an adrenal mass. Screening rates were higher in patients with multiple risk factors: 16.8% for ≥3, 5.7% for 2, and 2.5% for 1 criterion. Multiple logistic regression showed that the odds of PA screening were higher in patients with hypokalemia: odds ratio (95% CI): 3.0 (2.7-3.3); women: 1.3 (1.2-1.4); Black versus White: 1.5 (1.4-1.7); those with obstructive sleep apnea, chronic renal disease, stroke, and dyslipidemia. Conclusions Consideration for PA is given in a small subset of at-risk patients, and typically after comorbidities have developed.
