Cost Effectiveness of Additional Preoperative Telephone Call to Increase Surgical Preparedness: Analysis of a Randomized Clinical Trial.

Introduction and Hypothesis: There is a need for cost effective interventions that increase surgical preparedness in urogynecology. Methods: We performed an ancillary prospective economic evaluation of the Telehealth Intervention to Increase Patient Preparedness for Surgery (TIPPS) Trial, a randomized multicenter trial that evaluated the impact of a preoperative telehealth call on surgical preparedness in women undergoing urogynecologic surgery. A within-trial analysis from the health care sector and societal perspective was performed. Cost-effectiveness was computed from health care sector and societal perspectives, with an 8-week time horizon. Results: A total of 126 women were included in our analysis. QALYs gained were similar between groups (telehealth 0.1414 + 0.0249; usual care 0.1409 + 0.0179). The cumulative mean per-person costs at 8 weeks from the healthcare sector perspective were telehealth call: $8696 +/– 3341; usual care: $8473 +/– 3118 (p = 0.693) and from the societal perspective were telehealth call: $11,195 + 5191; usual care: $11,213 +/– 4869 (p = 0.944). The preoperative telehealth call intervention was not cost effective from the health care sector perspective with an ICER of $460,091/QALY (95%CI –$7,382,608/QALY, $7,673,961) using the generally accepted maximum willingness to pay threshold of $150,000/QALY (Neumann et al. N Engl J Med. 371(9):796–7, 2014). From the societal perspective, because incremental costs per QALY gained were negative $–35,925/QALY (95%CI, –$382,978/QALY, $317,226), results suggest that preoperative telehealth call dominated usual care. Conclusions: A preoperative telehealth call is cost effective from the society perspective. Clinical Trial Registration: Registered with http://ClinicalTrials.gov.
