Abstract Background The COVID19 pandemic highlighted deficiencies in interdisciplinary risk-communication in an intermediate care unit, based in a 30 bed independent care home, into which the hospital organisation assigns medical, pharmacy, physiotherapy, occupational therapy and social work teams to provide post-acute care rehabilitation for adults. Mean length of stay is 20 days and > 75% return home. Weekly bed turnover is approximately 15%. Methods Semi-structured interviews with nursing leaders and a weighted questionnaire for multidisciplinary team were used to determine baseline levels of confidence around environmental and resident-specific risk awareness. An Ishikawa diagram analysed factors contributing to risk-communication. The ‘Chain Of Care’ vision for care home environments incorporated a Multidisciplinary Safety Brief. Five iterations occurred before reaching standardisation. A post-implementation weighted questionnaire collated qualitative information on confidence change. The Safety Brief supplements intra-professional group handover processes. Duration ranged 90-120 seconds, occurring at shift commencement and 12.00 h daily. Retained documentation is available for inspectors. Results The Safety Brief as a communication tool: 86% of the team found it useful; 71% found that it had the ‘right amount’ of detail; and 62% found that it was of the ‘right duration’. Areas of greatest ‘swing’ towards INCREASED or SLIGHTLY INCREASED confidence in awareness of...: 72%, deaths in last 24 hours; 68%, planned discharges today; 67%, residents at risk of falling/had fallen within 48 hours; 67%, residents with same name; 66%, bed-availability; 63%, infection risks; 62%, experiencing delirium; 62%, living with dementia; 59%, scheduled appointments today; and 52%, those receiving palliative care. Conclusion A Multidisciplinary Safety Brief increased/slightly increased multidisciplinary team confidence in environmental and resident-specific risks in a care home environment. Risk-communication in any environment is complex especially if subject to frequent change. Communication tools need to be tailored to microsystem, systematic, comprehensive, yet brief and intuitive. Generalisability to non-intermediate care, non-geriatrician supported care home environments was considered iteratively.
