Purpose <p>To develop a rigorous and standardized digital home self-care rehabilitation program for breast cancer patients’ post-surgery, based on traditional Chinese medicine (TCM) nursing diagnostics.</p> Methods <p>The initial draft of a digital rehabilitation module based on the WeChat mini-program was prepared through Literature research, patient surveys, expert interviews, And group discussions. A two-round Delphi method was used to consult 16 experts, revising, adding, and removing elements to finalize the rehabilitation plan.</p> Results <p>The response rate for both rounds of the Delphi expert consultation was 100%, with authority coefficients of 0.813 And 0.841, respectively, and Kendall’s coefficient of concordance values of 0.789 And 0.513 (both <i>P</i>&#xa0;&lt;&#xa0;0.001). The final plan includes 3 primary entries, 8 secondary entries, And 10 tertiary entries. Analytical hierarchy process results showed that the consistency ratio (CR) values for all matrices of the tertiary entries were &lt;&#xa0;0.1, meeting the requirements for consistency tests.</p> Conclusion <p>The constructed digital home self-care rehabilitation program for postoperative breast cancer patients, developed through evidence synthesis and expert consensus using Delphi consultation and AHP, is methodologically rigorous, reliable, and clinically applicable.</p> Trial registration <p>ClinicalTrials.gov Identifier: ITMCTR2024000368</p>
