Aim

To identify whether the introduction of low‐low hospital beds resulted in changes in the incidence, associated patient harms and event characteristics of bed‐related falls where implemented.

Design

This retrospective quality improvement study covered 36 months: 18 months pre‐intervention and 18 months post‐intervention.

Methods

Our analysis incorporated patient fall data from a hospital in upstate New York. Pre‐/post‐intervention data covered 18 months on either side of introduction at the units of implementation. Data were sourced from contemporaneously recorded incident reports and the organisation's business intelligence records. Analysis addressed the incidence rate, frequency, patient harm classification and recurrence of bed‐related falls, as well as Morse Fall Scale risk classification, patient age, gender and other individualised risk factors. Lastly, we reviewed the presence of individualised interventions, staff assistance during the event, patient census and staffing ratios. Chi‐square goodness of fit tests were employed to compare the distribution, and Brunner‐Munzel tests the stochastic equality, of the pre‐ and post‐implementation categorical and continuous data.

Results

There were no significant differences in the incidence rate of bed‐related falls, patient harms or in the need for medical intervention following implementation of the low‐low hospital beds. Neither were there any significant differences in the proportion of events resulting in detectable harm or the need for medical intervention post‐implementation. The total number of bed‐involved falls substantively increased following implementation of the low‐low beds, as did the number of events resulting in detectable harms and medical intervention. Among these, substantive increases were noted among events resulting in minor temporary harm and patients referred for diagnostic imaging. The number of events involved patients experiencing recurrent falls of any kind increased significantly post‐implementation.

Conclusion

We found that the introduction of low‐low hospital beds preceded no change in the incidence of bed‐related falls, associated patient harms or the need for post‐event medical intervention where implemented. While data limitations precluded definitive determination with respect to certain event characteristics, several post‐implementation changes, including substantive increases in the number of falls occurring during ingress and egress, may suggest a potential for relationship worthy of future study.

Implications and Impact

Low‐low hospital beds are purported to help reduce the occurrence and severity of bed‐related falls, both serious problems in inpatient settings. This study describes null outcomes following an implementation of such beds, with implications for adoption in similar settings.

Reporting Method

We adhered to the relevant Enhancing the Quality and Transparency of Health Research guidelines, specifically following the Standards for Quality Improvement Reporting Excellence standards.

Patient or Public Contribution

No patient or public involvement in the design or conduct of the study. Nurses and medical staff were involved in intervention implementation, data collection and the conception, design and conduct of the study.
