Tool and machinery-related hand injuries: a review of national Hospital Episodes Statistics and data from a tertiary hand unit.

We sought to identify national trends in tool and machinery-related hand injuries. Hospital Episodes Statistics data in England from 1998 to 2017 were analysed. Data from our hand unit from 2011 to 2017 were also reviewed to establish the types of tool and machinery causing injury. During the 19-year study period 210,291 admissions occurred as a result of tool and machinery-related injuries. The overall incidence rate and mean age increased. The largest increase in incidence rate was in the oldest age group (75 years+). The incidence rate in children fell. During the period studied, 2150 patients underwent surgery in our unit for tool and machinery-related injuries. The hand was involved in 2069 (96%) of the injuries. Adult injuries were caused by a similar proportion of types of tool or machinery in all age groups. This study demonstrates a clear and sustained trend of increasing incidence of tool and machinery-related injuries in adults. The largest increase is in older patients.Level of evidence: IV.

An infective cause for the limping child.

A 7-year-old girl presented with left hip pain and a limp, in the absence of any other systemic features, having recently been treated for a urinary tract infection. Examination revealed limited active hip movements on the left, with a tendency to weight bear on the contralateral side. Biochemical investigations were significant for raised inflammatory markers, and subsequent MRI imaging revealed osteomyelitis of the left pubis and ischium with an associated large soft tissue collection. Treatment was bimodal with surgical drainage and long-term antibiotics. The patient consequently recovered, without significant effect on either growth or mobility.

Do Antibiotic-impregnated Calcium Sulfate Beads Improve the Healing of Neuropathic Foot Ulcers With Osteomyelitis Undergoing Surgical Debridement?

BACKGROUND: Neuropathic foot ulcers are common and difficult to treat. Calcium sulfate (CAS) has been used for antibiotic delivery in the treatment of osteomyelitis with success. Recent case series suggest success in treating osteomyelitis of the foot with CAS in a mean time to healing of 4 months; however, few studies with a control group for comparison exist. OBJECTIVE: This study aims to determine if antibiotic-impregnated CAS beads improved the healing of neuropathic foot ulcers with proven osteomyelitis undergoing surgical debridement. MATERIALS AND METHODS: A consecutive retrospective cohort study of 50 patients undergoing surgical debridement of neuropathic foot ulcers for osteomyelitis from December 2015 to May 2016 was performed. Exclusion criteria consisted of amputations and microbiology findings inconsistent with osteomyelitis. Patients were divided into 2 groups: the surgical debridement (SD) group was treated with SD alone and the other (CAS) was treated with debridement and implantation of vancomycin- and gentamicin-impregnated CAS beads. RESULTS: After exclusion criteria, 42 patients were included: 13 in the SD group and 29 in the CAS group. In the SD group, the mean time to healing was 5.8 months (range, 2-9 months), and in the CAS group, it was 5.5 months (range, 2-13 months). There was no significant difference in ulcer healing (P = .81), time to healing (P = .79), reoperation rate (P = .51), length of stay (P = .74), or mortality (P = .13) between the 2 groups. CONCLUSIONS: Ulcer healing in patients treated with antibiotic-impregnated CAS beads did not show statistical significance. Healing rates in both groups were similar to those in recent literature. Surgical debridement alone may be as effective as supplementation with local antibiotics in a bioabsorbable carrier.

Leadership behaviours and healthcare research performance: prospective correlational study.

OBJECTIVES: The aims of the study were to determine whether differences in leadership self-perception/behaviour in healthcare researchers may influence research performance and to evaluate whether certain leadership characteristics are associated with enhanced leadership efficiency in terms of motivation, effectiveness and satisfaction. DESIGN AND PARTICIPANTS: All Faculty of Medicine Professors at Imperial College London (n=215) were sent the Multifactor Leadership Questionnaire (MLQ) Self form as a means of evaluating self-perception of leadership behaviours. MAIN OUTCOME MEASURES: For each professor, we extracted objective research performance measures (total number of publications, total number of citations and h index) from 1 January 2007 to 31 December 2009. The MLQ measured three leadership outcomes, which included motivation, effectiveness and satisfaction. Regression analysis was used to determine associations. RESULTS: A total number of 90 responses were received, which equated to a 42% response rate. There were no significant correlations between transformational, transactional or passive/avoidant leadership behaviours and any of the research performance measures. The five transformational leadership behaviours (ie, idealised attributes (IA), idealised behaviours (IB), inspirational motivation (IM), intellectual stimulation (IS), individual consideration (IC)) were highly significant predictors of leadership outcomes, extra effort (all B>0.404, SE=0.093-0.146, p<0.001), effectiveness (IA, IM, IS, IC B>0.359, SE=0.093-0.146, p<0.001; IB B=0.233, SE=0.103, p=0.026) and satisfaction (IA, IM, IS, IC B>0.483, SE=0.086-0.139, p<0.001; IB B=0.296, SE=0.101, p=0.004). Similarly, contingent reward was a significant predictor of extra effort (B=0.400, SE=0.123, p=0.002), effectiveness (B=0.353, SE=0.113, p=0.002) and satisfaction (B=0.326, SE=0.114, p=0.005). CONCLUSIONS: This study demonstrates that transformational leadership and contingent reward positively influence leadership efficiency in healthcare researchers. Although we did not show an association between leadership behaviours and research performance metrics, further studies using contextual performance measures at team and organisational levels are required.
