Objective This study aimed to examine health care workers’ (HCWs) perceptions of hospital disaster planning and preparedness within the context of building resilient health care systems. It also evaluated HCWs’ involvement in the planning process.

Methods Thirteen HCWs from 2 Queensland hospitals participated in in-depth, semi-structured interviews. These interviews were audio-recorded with participant consent and transcribed verbatim. Transcripts, recordings, and participant details were coded for confidentiality. Thematic analysis was used to identify essential patterns in the data and make sense of them.

Results HCWs’ perspectives on disaster planning underscored the importance of comprehensive planning, business continuity, proactive approaches emphasizing anticipation and risk mitigation, and implementation of established plans through training, resource management, and operational readiness. HCWs’ participation in planning ranged from high engagement through collaboration and continuous improvement to moderate or lower levels focusing on regulatory compliance and resource allocation.

Conclusions This study highlights HCWs’ views regarding disaster planning and preparedness for building resilient health care systems. HCWs emphasised comprehensive planning and proactive preparedness, aligning with global priorities for disaster risk reduction. They stress the importance of education, training, operational readiness, and continuous improvement. This study underlines the vital role of HCWs’ participation in disaster planning and the need for comprehensive training initiatives.
