Fall incidents in nursing home residents: development of a predictive clinical rule (FINDER).

ABSTRACT:

Objectives

To develop (part I) and validate (part II) an electronic fall risk clinical rule (CR) to identify nursing home residents (NH-residents) at risk for a fall incident.

Design

Observational, retrospective case-control study.

Setting

Nursing homes.

Participants

A total of 1668 (824 in part I, 844 in part II) NH-residents from the Netherlands were included. Data of participants from part I were excluded in part II.

Primary and secondary outcome measures

Development and validation of a fall risk CR in NH-residents. Logistic regression analysis was conducted to identify the fall risk-variables in part I. With these, three CRs were developed (ie, at the day of the fall incident and 3 days and 5 days prior to the fall incident). The overall prediction quality of the CRs were assessed using the area under the receiver operating characteristics (AUROC), and a cut-off value was determined for the predicted risk ensuring a sensitivity ≥0.85. Finally, one CR was chosen and validated in part II using a new retrospective data set.

Results

Eleven fall risk-variables were identified in part I. The AUROCs of the three CRs form part I were similar: the AUROC for models I, II and III were 0.714 (95% CI: 0.679 to 0.748), 0.715 (95% CI: 0.680 to 0.750) and 0.709 (95% CI: 0.674 to 0.744), respectively. Model III (ie, 5 days prior to the fall incident) was chosen for validation in part II. The validated AUROC of the CR, obtained in part II, was 0.603 (95% CI: 0.565 to 0.641) with a sensitivity of 83.41% (95% CI: 79.44% to 86.76%) and a specificity of 27.25% (95% CI 23.11% to 31.81%).

Conclusion

Medication data and resident characteristics alone are not sufficient enough to develop a successful CR with a high sensitivity and specificity to predict fall risk in NH-residents.

Project description:AIMS AND OBJECTIVES:To explore nursing home residents' perspectives on their relationships with other residents, family members and staff. BACKGROUND:The cultivation of social relationships is central to promoting well-being in nursing homes, as these relationships allow residents, family members and staff to be valued as unique persons and empowered as partners in care. Few studies have examined how nursing home residents perceive the relationships in their social networks, both within and beyond the facility. DESIGN:Qualitative secondary analysis. METHODS:We analysed individual and group interviews obtained during "stakeholder engagement sessions" with cognitively intact residents (N = 11 sessions; N = 13 participants) from two nursing homes in North Carolina. The interviews were conducted as part of a larger study on person-directed care planning. We integrated thematic and narrative analytic approaches to guide the analysis of interview data, using a three-cycle coding approach. The COREQ checklist was followed. RESULTS:Four broad themes emerged from this analysis: (a) peer relationships foster a sense of belonging, purpose, achievement and significance; (b) residents' relationships with family members support a sense of belonging, continuity and significance; (c) mutual respect and reciprocity between residents and nursing home staff promote a sense of belonging and significance; and (d) organisational factors pose barriers to forging meaningful relationships. Each type of relationship-peer, family and staff-made distinctive contributions residents' psychosocial well-being. CONCLUSION:Recognising the diverse roles of different actors from residents' social networks raises questions for future research to optimise the distinctive contributions of network members that promote residents' psychosocial well-being. RELEVANCE TO CLINICAL PRACTICE:This study highlights the need for nursing home staff to understand how residents' social relationships influence residents' psychosocial outcomes. Staff training programmes are needed to support residents' rights and to dispel inaccurate interpretations of regulations that threaten sustained meaningful relationships.
