6-PACK programme to decrease fall injuries in acute hospitals: cluster randomised controlled trial

OBJECTIVE:  To evaluate the effect of the 6-PACK programme on falls and fall injuries in acute wards. DESIGN:  Cluster randomised controlled trial. SETTING:  Six Australian hospitals. PARTICIPANTS:  All patients admitted to 24 acute wards during the trial period. INTERVENTIONS:  Participating wards were randomly assigned to receive either the nurse led 6-PACK programme or usual care over 12 months. The 6-PACK programme included a fall risk tool and individualised use of one or more of six interventions: "falls alert" sign, supervision of patients in the bathroom, ensuring patients' walking aids are within reach, a toileting regimen, use of a low-low bed, and use of a bed/chair alarm. MAIN OUTCOME MEASURES:  The co-primary outcomes were falls and fall injuries per 1000 occupied bed days. RESULTS:  During the trial, 46 245 admissions to 16 medical and eight surgical wards occurred. As many people were admitted more than once, this represented 31 411 individual patients. Patients' characteristics and length of stay were similar for intervention and control wards. Use of 6-PACK programme components was higher on intervention wards than on control wards (incidence rate ratio 3.05, 95% confidence interval 2.14 to 4.34; P<0.001). In all, 1831 falls and 613 fall injuries occurred, and the rates of falls (incidence rate ratio 1.04, 0.78 to 1.37; P=0.796) and fall injuries (0.96, 0.72 to 1.27; P=0.766) were similar in intervention and control wards. CONCLUSIONS:  Positive changes in falls prevention practice occurred following the introduction of the 6-PACK programme. However, no difference was seen in falls or fall injuries between groups. High quality evidence showing the effectiveness of falls prevention interventions in acute wards remains absent. Novel solutions to the problem of in-hospital falls are urgently needed.

Deducing the reachable space from fingertip positions

The reachable space of the hand has received significant interests in the past from relevant medical researchers and health professionals. The reachable space was often computed from the joint angles acquired from a motion capture system such as gloves or markers attached to each bone of the finger. However, the contact between the hand and device can cause difficulties particularly for hand with injuries, burns or experiencing certain dermatological conditions. This paper introduces an approach to find the reachable space of the hand in a non-contact measurement form utilizing the Leap Motion Controller. The approach is based on the analysis of each position in the motion path of the fingertip acquired by the Leap Motion Controller. For each position of the fingertip, the inverse kinematic problem was solved under the physiological multiple constraints of the human hand to find a set of all possible configurations of three finger joints. Subsequently, all the sets are unified to form a set of all possible configurations specific for that motion. Finally, a reachable space is computed from the configuration corresponding to the complete extension and the complete flexion of the finger joint angles in this set.

Factors associated with accidental injuries in children with ADHD-combined type: more than a motor problem?

OBJECTIVE: We explored the relationship between accidental injuries, motor impairment, and co-occurring autism spectrum disorder (ASD) symptoms in children with ADHD-combined type (ADHD-CT).

METHOD: Participants were 32 male children diagnosed with ADHD-CT and 23 typically developing male children (7-12 years, full scale IQ [FSIQ] > 80). Parents completed a customized questionnaire on the occurrence of accidental injuries (e.g., bruises, cuts) their child experienced in the past 12 months. Motor proficiency was assessed using the Movement ABC-2 (MABC-2). Parents rated motor, ADHD-CT, ASD, and anxiety symptoms.

RESULTS: Children with ADHD-CT had significantly increased parent-reported accidental injuries compared with typically developing children. Among children with ADHD-CT, Spearman's rho rank correlations revealed no association between increased accidental injuries and MABC-2 score, but significant associations with increased hyperactivity/impulsivity, ASD, and anxiety symptoms.

CONCLUSION: Although these findings require validation, they suggest a need for further research investigating the contribution of co-occurring ASD and anxiety symptoms to accidental injuries in children with ADHD-CT.

Comparison of two measures of work functioning in a population of claimants with physical and psychological injuries

Research has focused on advancing our understanding of strategies to improve return to work outcomes following a physical injury. There has been limited research on the different types of supports needed for workers returning to work following a psychological injury. Developing a better understanding of work limitations when people are back at work is a key step in the development of strategies in this area. Unfortunately, measurement tools have been established separately by injury type, limiting research opportunities to compare differences in work limitations. In this article, we compare two measures of work functioning in a population of claimants that have returned to work following a musculoskeletal or psychological injury: a modified version of the Work Limitations Questionnaire (WLQ) developed for workers with physical injuries and the Lam Employed Absence Productivity Scale (LEAPS) developed for workers with mental health claims. A telephone questionnaire was administered to 214 claimants who returned to work following a claim for a psychological injury or a musculoskeletal injury. While the modified WLQ detected differences in work limitations by injury type, there were no significant differences in levels of work functioning detected by the LEAPS. The comparison demonstrated the value of including questions about work limitations that go beyond mental and interpersonal demands for claimants with psychological injuries; however, there is also a need to limit questions about physical constraints. A modified version of the WLQ is recommended to further our understandings of the similarities and differences in the experiences of workers with psychological versus physical injuries.
