Background: Few data are available on the temporal patterns of health resource utilization (HRU) and expenditures around paroxysmal supraventricular tachycardia (PSVT) diagnosis. This study assessed the longitudinal trends in HRU and expenditures in the 3 years preceding and subsequent to PSVT diagnosis.

Methods: Adult patients (age 18-65 years) with newly diagnosed PSVT were identified using administrative claims from the IBM MarketScan Research Database between January 1, 2008 and December 31, 2016 and propensity-score matched (1:1) with non-PSVT controls.

Results: Among the 12,305 PSVT patients compared with matched controls, PSVT was associated with statistically significant higher annual rates of emergency department visits, physician office visits, inpatient hospitalizations, and diagnostic testing. HRU increased in the years preceding PSVT diagnosis, reaching its peak in the year following PSVT diagnosis. Over the 6-year follow-up period, PSVT was associated with higher mean annual per patient expenditures ($12,665) compared to matched controls ($6,004; P < .001). Upon diagnosis of PSVT, the mean expenditures per PSVT patient doubled from $11,714 in the year immediately preceding index diagnosis to $23,335 in the first postdiagnosis year. Inpatient services, diagnostic testing, and ablation procedures were the principle drivers of higher mean expenditures in the first year post-PSVT diagnosis versus the year prior to PSVT diagnosis.

Conclusions: PSVT presents a substantial economic burden to health care systems. The annual expenditure per PSVT patient is within the range previously reported for atrial fibrillation. The increased HRU and expenditures in the year following diagnosis, which do not return to baseline, suggest a potential gap in non-interventional, long-term PSVT management.
