Redesigning Pre-surgery Patient Journeys With Telehealth

Prior to elective surgery, patients undergo preanaesthesia assessment to ensure timely optimisation of medical conditions that could adversely impact perioperative outcomes. Preadmission Service (PAS) clinic nurses at KK Hospital perform pre-surgery triage to identify patients requiring outpatient anaesthetic review. PAS data shows that only 8% of same-day-admission (SDA) patients needed an anaesthetist's review; the majority (92%) can be safely triaged to receive preanaesthesia assessment on the day of surgery. The aim of this study is to investigate the service re-design, efficacy and effectiveness of a new telehealth pre-surgery model of care for elective SDA patients. The investigators hypothesize that the telehealth pre-surgery new model of care will achieve an expected 50% uptake for SDA patients as the primary outcome during implementation. Secondary outcomes are patient cost savings, patient experience of the new model of care, and staff experience of the new workflow. The investigators will use a sequential exploratory mixed methods study design, consistent with the 5-stage model for telehealth research. An implementation science framework - the Normalisation Process Theory, underpins our 3-phase study. Phase 1 (service redesign) explores the feasibility of presrugery telehealth via semi-structured interviews of patients and healthcare staff. Phase 2 (preimplementation) investigates efficacy of the telehealth model of care by addressing service fidelity, and patient and staff experience using administrative data. Phase 3 is a pragmatic trial to ascertain effectiveness of the telehealthmodel of care, addressing the primary and secondary outcomes stated. This novel study using implementation science to redesign and implement presurgery telehealth will inform scale-up, spread, and sustainability of a new model of care within SingHealth and other health clusters in Singapore.
