Introduction :
The Circadian Lighting System (CLS) is an innovative solution widely adopted in Northern European hospitals. It imitates natural sunlight and provides cycled lighting that can improve sleep quality. However, there is currently no experience for CLS in local hospitals. Introduction of new innovation in local hospitals is challenging because of numerous concerns and resistances to change. Besides the Proof-Of-Concept, it is crucial to build users’ trust in new healthcare technology.
Objectives :
1. Proof-Of-Concept to demonstrate value of CLS
2. Strategies to facilitate adoption of CLS in ward and gain trust from key stakeholders in adoption of CLS under the Lai King Building Expansion Capital Project.
Methodology :
1. Proof-Of-Concept (POC)
A trial test for CLS was set up in North Lantau Hospital Extended Care Ward from 17 July 2024 to 25 October 2024. Part I of the trial aimed to compare the sleep quality of inpatients between intervention group (n=47) and control group (n=63). Part II aimed to investigate the effectiveness of system to alert staff for unattended patients exiting their beds by the motion sensor system. Part III aimed to collect feedback from patients and staff regarding their experiences with the system.
2. Strategies to make change and trust
i) Early engagement and education of key stakeholders including clinical staff, the Facility Management Department, Procurement Team and Infection Control Team to explain the benefits to patients, address their concerns and prepare a contingency plan with a designated support team to resolve technical issues.
ii) Deliberation to clinical governance and hospital management the value of CLS in patient’s outcome with supporting evidences and perform feasibility study to ensure operational readiness
Result & Outcome :
The Trial Test proofed that CLS could improve sleep quality, showing a 40.4% improvement in the Insomnia Severity Index for patients with a length of stay > 6 days. Also, the CLS could enhance patient safety by alerting staff when patients exited their beds at night. Patients were satisfied with the cycled lighting environment and staff agreed that CLS could assist their daily work and promote better quality of care. The POC result was presented in hospital management and supported to adopt the system in the Lai King Building Expansion Project.
