Introduction: Echocardiography is commonly performed in the evaluation of patients with pulmonary hypertension (PH). The report summary often serves to guide the future evaluation of these patients. Our aim was to explore the relationship between the echocardiography reports of patients with PH and referral to a PH specialty clinic.
Methods: A random sample of 500 echocardiographic reports of patients with an estimated right ventricular systolic pressure (RVSP) greater than 40 mm Hg between 2006 and 2014 was selected from the institutional database of a single academic center. Referral to the PH clinic was determined by evaluating the electronic medical record. Univariate and multivariate logistic regression analyses were performed to identify characteristics associated with referral.
Results: Pulmonary hypertension was mentioned in 31% of the report summaries, and only 4.6% were referred to the PH clinic. Variables associated with referral were younger age, indication for echocardiography, higher right atrial and ventricular (RV) systolic pressures, RV dilatation, mention of PH in the summary, and higher left ventricular ejection fraction. Mention of PH in the summary was the variable most strongly associated with referral (adjusted odds ratio 4.6, 95% CI 1.5-14.2).
Conclusion: Pulmonary hypertension was infrequently mentioned in the summary of echocardiography reports of patients with RVSP >40 mm Hg. Referral to the PH clinic was rare but occurred more often following the mention of PH in the summary. Explicit mention of the presence of PH in the echocardiography report summary may facilitate referral to a specialty clinic and allow more comprehensive evaluation of PH.
