A novel patient decision aid for aftercare in breast cancer patients: A promising tool to reduce costs by individualizing aftercare

摘要: Abstract Objective A patient decision aid (PtDA), was developed to support breast cancer patients making choices about their aftercare. The aim of this pilot test the effects PtDA on Shared Decision Making (SDM), Evaluation (DES) in patients, consultation time, choice aftercare and hospital costs. Methods prospective before-and-after study including a control (no PtDA-usage) experimental group (PtDA-usage during consultation) conducted six hospitals. Patients were offered between intensive (face-to-face consultations) less (telephonic or demand All filled out three validated questionnaires (baseline (T0), directly after (T1), months later (T2)), assessing demographics SDM(T1) DES (T1, T2). Hospital costs assessed from patients' files (T2). Effect sizes ( ɳp2: 0.01 = small; 0.06 = medium; 0.14 = large; φ: 0.1 = small, 0.3 = medium, 0.5 = large) p-values calculated using both univariate multivariate GLMs, repeated measures GLM chi-square-tests. Results small improvement SDM ɳp2 = 0.02) an effect ɳp2 = 0.10) found group. Significantly more PtDA-users (51% vs. 29%, φ = 0.22) chose aftercare, leading reduction (122 92 Euro, ɳp2 = 0.01), large increase average time (12.5 min; ɳp2 = 0.29). Conclusion This showed promising can be further potentially reduce increased time.
