By performing meticulous sentiment analysis, we aim to understand the subjective sentiments of learners engaging with nature-based digital interventions. To achieve this, we integrate a Bidirectional Long Short-Term Memory (BiLSTM) network with a Conditional Random Field (CRF). The BiLSTM captures word associations in both forward and backward directions, feeding these results into the CRF network to establish the conditional distribution between the feature function and labels. This ensures high-quality feature extraction, precise label assignment, and the derivation of evaluation metrics.

Themes from the review were supported by implementation guidelines for DHS and the combined evidence informed the implementation strategy. Each theme was matched with specific steps for implementing BT Online.</p><p><strong>Results: </strong>The rapid review identified 10 themes, namely, awareness of the new digital platform; institutional integration and support; data security, the quality, usability and accessibility of the platform; belief in the benefit of the platform; the need for holistic and tailored features; the timing of introducing the platform; engagement of healthcare professionals; and the re-definition of roles and workload. The themes were matched with 51 concrete implementation steps.</p><p><strong>Discussion: </strong>The purpose of the strategy was to minimise risk of implementation failure, consider the specific context of care and generate a reference framework to evaluate BT Online prior to upscaling to use outside the research context. Our method contributes a novel approach of developing an evidence-informed rigorous implementation strategy if existing implementation frameworks do not apply.</p>","PeriodicalId":51333,"journal":{"name":"DIGITAL HEALTH","volume":"11 ","pages":"20552076251316713"},"PeriodicalIF":2.9,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11822819/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143416136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
