Implementing early rehabilitation and mobilisation for children in UK paediatric intensive care units: the PERMIT feasibility study.

ABSTRACT

Background: Early rehabilitation and mobilisation encompass patient-tailored interventions, delivered within intensive care, but there are few studies in children and young people within paediatric intensive care units. Objectives: To explore how healthcare professionals currently practise early rehabilitation and mobilisation using qualitative and quantitative approaches; co-design the Paediatric Early Rehabilitation and Mobilisation during InTensive care manual of early rehabilitation and mobilisation interventions, with primary and secondary patient-centred outcomes; explore feasibility and acceptability of implementing the Paediatric Early Rehabilitation and Mobilisation during InTensive care manual within three paediatric intensive care units. Design: Mixed-methods feasibility with five interlinked studies (scoping review, survey, observational study, codesign workshops, feasibility study) in three phases. Setting: United Kingdom paediatric intensive care units. Participants: Children and young people aged 0-16 years remaining within paediatric intensive care on day 3, their parents/guardians and healthcare professionals. Interventions: In Phase 3, unit-wide implementation of manualised early rehabilitation and mobilisation. Main outcome measures: Phase 1 observational study prevalence of any early rehabilitation and mobilisation on day 3. Phase 3 feasibility study acceptability of early rehabilitation and mobilisation intervention; adverse events; acceptability of study design; acceptability of outcome measures. Data sources Searched Excerpta Medica Database, Cumulative Index to Nursing and Allied Health Literature, MEDLINE, PEDro, Open grey and Cochrane CENTRAL databases. Review methods: Narrative synthesis. Results: In the scoping review we identified 36 full-text reports evaluating rehabilitation initiated within 7 days of paediatric intensive care unit admission, outlining non-mobility and mobility early rehabilitation and mobilisation interventions from 24 to 72 hours and delivered twice daily. With the survey, 124/191 (65%) responded from 26/29 (90%) United Kingdom paediatric intensive care units; the majority considered early rehabilitation and mobilisation a priority. The observational study followed 169 patients from 15 units; prevalence of any early rehabilitation and mobilisation on day 3 was 95.3%. We then developed a manualised early rehabilitation and mobilisation intervention informed by current evidence, experience and theory. All three sites implemented the Paediatric Early Rehabilitation and Mobilisation during InTensive care manual successfully, recruited to target (30 patients recruited) and followed up the patients until day 30 or discharge; 21/30 parents consented to complete additional outcome measures. Limitations: The findings represent the views of National Health Service staff but may not be generalisable. We were unable to conduct workshops and interviews with children, young people and parents to support the Paediatric Early Rehabilitation and Mobilisation during InTensive care manual development due to pandemic restrictions. Conclusions: A randomised controlled trial is recommended to assess the effectiveness of the manualised early rehabilitation and mobilisation intervention. Future work A definitive cluster randomised trial of early rehabilitation and mobilisation in paediatric intensive care requires selection of outcome measure and health economic evaluation.

Early rehabilitation and mobilisation, within the first week of intensive care admission, can improve the speed of recovery from illness or injury in adults. However, there is a lack of evidence about whether critically unwell children benefit from early rehabilitation and mobilisation. We aimed to identify which patients may benefit from early rehabilitation and mobilisation. Also, to develop and test a manual of early rehabilitation and mobilisation using the best evidence and expertise ­ called the Paediatric Early Rehabilitation and Mobilisation during InTensive care manual. Then evaluate whether the manual could be implemented safely in paediatric intensive care units and was acceptable to staff and families. We undertook in respect of early rehabilitation and mobilisation review of existing research; national survey of practice (124 staff); gathered information about current conduct (15 paediatric intensive care units, 169 patients); spoke to experts (18 people); developed the Paediatric Early Rehabilitation and Mobilisation during InTensive care manual to guide paediatric intensive care unit staff; Tested the Paediatric Early Rehabilitation and Mobilisation during InTensive care manual in three paediatric intensive care units with 30 patients; gathered feedback from healthcare professionals via weekly 'debriefs' (47), interviews (13) and surveys (118), and from parents via parent-completed questionnaires (21) and interviews (14). Despite being regarded as important, currently early rehabilitation and mobilisation practice is inconsistent, not considered 'early' enough and often focuses on low-risk activities conducted on the bed. Introducing the Paediatric Early Rehabilitation and Mobilisation during InTensive care manual as part of a trial was acceptable and feasible and helps standardise delivery to unwell children. Measuring child and parent reported outcomes was acceptable but follow-up at 30 days was incomplete. A larger trial of early rehabilitation and mobilisation, involving more paediatric intensive care units, is feasible and required to demonstrate benefit to children.
