The impact of an End-PJ-Paralysis quality improvement intervention in post-acute care: an interrupted time series analysis

The “End-PJ-Paralysis” social movement has promoted global recognition of the problem of low activity levels for hospitalised older adults, but whether aligned quality improvement programmes impact length of stay or adverse events is unknown. To determine the impact of a multicomponent intervention, which included data displays, exercise groups, a clothing repository, widespread promotion, and targeted education for staff and patients to promote dressing and activity, we conducted an interrupted time series analysis. Although there was no clear impact upon length of stay or fall or pressure rates after 12 months, this is an important finding for other centres implementing their own “End-PJ-Paralysis” interventions as it highlights that such programmes are not associated with increased falls, as commonly feared.
