Abstract

Objective: To develop a novel patient decision aid (PtDA) for parents considering tonsillectomy for their children diagnosed with obstructive sleep apnea (OSA) and compare it to validated scales related to decision making in this context. These included scales for decisional conflict (DC) and shared decision making (SDM). Methods: A parental survey during 2017 to 2018 in a tertiary care pediatric otolaryngology clinic was conducted comparing a validated Decisional Conflict Scale (DCS) with a new PtDA that included an SDM scale, parental treatment goals, and knowledge about adenotonsillectomy and OSA. DCS scores range from 0 to 100 with values less than 25 considered to be low DC. The DQ was determined by a score on the PtDA. The PtDA was composed of a knowledge score, SDM score and 5 related values scored along a continuum (these were: resolution of symptoms, avoiding anesthesia, avoiding surgery, avoiding pain/bleeding, and resumption of normal behavior). A high score meant that all answers were consistent with choosing tonsillectomy and imply better DQ. Results: A total of 89 parents or guardians participated in the study. The mean DC score was 4.32 (95% CI: 2.57-6.07). The mean DQ score was 22.69 (95% CI: 21.86-23.51). Mean values score was 5.35 (95% CI: 5.05-5.65). The mean knowledge score was 9.00 (95% CI: 8.60-9.40). SDM score mean was 8.38 (95% CI: 7.85-8.91). Using Spearman's rho, DC versus DQ inversely correlated with a coefficient −.209 via a 2-tailed test ( P = .05). Cronbach's alpha for the DQ score was .78. Conclusion: DC scores overall were low for the group. DQ, as measured with the novel PtDA, had an inverse correlation with DC scores, suggesting validity of the proposed PtDA. Our instrument has potential use as a PtDA for parents who are offered tonsillectomy for their children.
