37% of falls caused head impact, unaffected by hand impact (which occurred in 71% of cases) Head impact more likely in forward falls, no effect of hand impact
AGREEMENT BETWEEN VIDEO FOOTAGE AND FALL INCIDENT REPORTS ON THE CIRCUMSTANCES OF FALLS IN LONG-TERM CARE Agreement = 45.5%

Clinical Effectiveness of Hip Protectors: from evidence to practice
Hip Protectors (HP) wearable pad or shield typically embedded in an undergarment or pant reduces fracture risk by attenuating the force applied to the proximal femur at impact “active” form of injury prevention; site-specific effectiveness depends on acceptance and adherence among users in wearing the device, and biomechanical performance of the device
Two factors primarily determine clinical effectiveness comfort • appearance • geometry • ease of putting on • materials • Laundering • mis-positioning • staff commitment • Compliance Biomechanical Effectiveness (adherence) Clinical Effectiveness

Hip Protector Placement
Some hip protectors do not cover the greater trochanter Source : Minns et al., Age and Ageing, 2007 31
Hip protectors cannot prevent fracture in all circumstances: use of hip protectors with poor biomechanical performance incorrect placement very week bones impact other then directly to the hip spontaneous fractures without obvious impact
BARRIERS AND FACILITATORS TO HIP PROTECTOR COMPLIANCE IN LONG-TERM CARE FACILITIES: A SYSTEMATIC REVIEW
Barriers and facilitators emerged at different socio-ecological levels
Key messages Organizational commitment Dedicated champion to motivate, mentor, and monitor Involve everyone responsible for resident safety Staff education of the benefits and correct use Engage and educate residents and families Choose from hip protector models with proven efficacy Put in place protocols for ensuring adequate supply, variety of models, correct fit, and laundering
The Bottom Line Hip protectors are effective for those wearing the device at the time of the fall Not all hip protectors are equally effective User compliance heavily influences their clinical effectiveness Many actions can be taken in LTC facilities to enhance compliance www.agingisacontactsport.com
Development and Testing of a Novel Adhesive Hip Protector pad for Acute Care Patients
Benefits of novel adhesive hip protector pads 1. Pad secured 2. Continuous protection 3. Decrease staff workload 4. No laundry requirements 5. One size fits all 6. Not patient specific 7. Longer shelf life 8. Lower unit cost
Feedback Positive feedback from patients and staff No side effects reported due to the pad or adhesive tape No complaints of pain when removing the pad Demonstrates the feasibility of a stick-on hip protector in the hospital setting Results will guide development of future pad prototypes 40
Next Steps Conduct a clinical trial comparing compliance rates between traditional garment hip protectors currently in use within Fraser Health Hospitals and the adhesive hip protector Conduct focus groups with the nurse staff to obtain qualitative information regarding pros and cons to the adhesive hip protector in comparison to the traditional garment hip protector

The Flooring for Injury Prevention (FLIP) Trial: Can Compliant Flooring Reduce Injuries Due to Falls in Long-Term Care?
Force reduction provided Force reduction provided by SmartCells during a by SmartCells during a simulated fall on the head simulated fall on the hip averaged 70% averaged 34% 34% Laing et al., Accident Analysis & Prevention, 2009
Compliant floors reduce peak force with minimal influence on balance or mobility of older women 15 women ranging in age from 65 - 90 yrs (mean = 75, SD = 8)
FLIP Trial will address 3 aims: 1. To determine the effect of compliant flooring on fall-related injuries in long-term care 2. To determine the effect of compliant flooring on healthcare utilization in long-term care 3. To assess perceptions about compliant flooring among key stakeholder groups
FLIP Trial Design New Vista = 236 rooms Common areas will Exclude 86 rooms - 49 Willow Grove (non-ambulatory) NOT be modified. Thus, - 37 floor cannot be raised 1” 3’ long transition ramps are required between 150 single-occupancy rooms across 4 villages hallways and common will be randomized within villages areas Intervention (INT) flooring Control (CON) flooring CON will also be installed 1” SmartCells w/ vinyl cover 1” plywood w/ vinyl cover in adjacent hallways Notification & Installation Primary outcome 16 rooms/wk for ~10 wks • moderate/severe fall-related injuries Secondary outcomes Assess baseline characteristics • all fall-related injuries • falls Track outcomes for 4 years
