Abstract Background Complex cases of older adults suffering from multimorbidity are continuing to increase in number. The integrated care team, overseen by a consultant geriatrician, aims to facilitate the management of stable complex cases in the community. Patient care is largely affected by their support system at home; therefore, it is of great importance to ensure that the patient’s primary carer is receiving the support they require to facilitate the older patients’ management in the community. Our aim is to assess carer stress levels before and after Multi-Disciplinary Team (MDT) integrated care intervention. Methods Study Population were carers of patients identified as complex cases by the integrated care team. Caregiver stress index was administered during the initial assessment and on the closing of active cases. The maximum score on this index is 13 with high stress classified as >7. Scores were added to a spreadsheet. This spreadsheet was reviewed, and relevant data was collated. One year assessed March 2021- March 2022. Results Carer stress information was collected on 62 of 112 identified complex cases (55%). Of these 55 of 96 individual patients were represented (57%). Average age 82 years old. 65% female and 35%, male. Range of carer stress scores observed 0- to 12. Of the 62 cases, 85% (53 cases) had a reduction in carer stress post-intervention(p<0.01). Of these 65% had a reduction below 7 (p<0.01). Mean score improvement 7. No carer stress indices disimproved post-treatment. Conclusion Multidisciplinary, patient-centred community care has a clear positive impact on the patient carer. Improvements in carer stress scores could be further evaluated as to the benefits of specific interventions in time. In future, a more large-scale collection and interpretation of data would need to occur for a more conclusive positive impact of the community based integrated care team to be confirmed.
