Background: The diagnosis of hand osteomyelitis requires correlation of clinical, radiological, and microbiological findings. The role of serum inflammatory markers in diagnosing and prognosticating hand osteomyelitis remains uncertain. We sought to determine the utility of inflammatory markers in the diagnosis and follow-up of hand osteomyelitis, and their ability to predict outcomes, particularly amputation. Methods: We retrospectively reviewed 146 patients diagnosed with hand osteomyelitis and with serum inflammatory marker levels measured after the onset of symptoms and within 14 days either side of diagnosis. Blood results at first presentation including white cell count (WCC), neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and C-reactive protein (CRP) were reviewed, and associations with amputations assessed. Follow-up markers taken at 15 to 60 days from diagnosis were analyzed where available. Results: Mean WCC and CRP at diagnosis were 9.2 (SD: 4.6) and 30.2 (SD: 42.4) respectively, compared with 8.2 (SD: 3.9) and 30.2 (SD: 42.4) at follow-up. At diagnosis, sensitivity of CRP was 74%, and WCC was 31%. Each marker had a low positive predictive value for amputation at diagnosis (Discussion: C-reactive protein has a higher sensitivity than WCC, NLR, and PLR when used as a diagnostic adjunct in hand osteomyelitis. White cell count and CRP both within reference ranges at diagnosis was highly negatively predictive against amputation.

Background The order-up-to inventory model is a method for identifying and maintaining the optimal product level for items that that hold value over time and have recurring demand. Typically, supermarkets utilise it to manage stock-levels of non-perishable goods. Local problem This project aimed to improve blood culture bottle supplies following reports by junior doctors of shortages when dealing with septic/unwell patients. Methods Data regarding blood culture bottle use was acquired from four hospitals within one trust in London (245 wards). The mathematical ‘order-up-to’ inventory model (an iterative Poisson distribution) was applied to the 6 months9 data. Interventions The model found three predictable levels of demand to stock wards with no shortages in 99.3% of circumstances (based on historical data). Wards were stocked with blood culture bottles as per their required demand. Results A collection method and infrastructure was designed to implement the new policy and was applied to a London tertiary centre. A review of doctors, nurses and ward-managers found significant improvements in supply with no shortages since the model was applied. Issues with the dataset were identified for intensive therapy unit / high dependency unit. Conclusions The ‘order-up-to’ inventory model provides a useful tool within hospitals for improving stock levels of blood cultures bottles and with that the satisfaction of trainees and patient safety.

Introduction Advances in the evidence base of acute thermal hand burns help to guide the management of these common injuries. The aim of this literature review was to evaluate recent evidence in the field over 10 years. Methods The Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols methodology was used as a guide for this literature review. PubMed, MEDLINE, EMBASE, CINAHL, and Google Scholar were searched for English language articles related to hand burns published between 2009 and 2018 inclusive, and the Cochrane Library was reviewed. Exclusion criteria were as follows: participants younger than 18 years, scar or contracture management, rehabilitation, outcomes assessment, late reconstruction, and electrical or chemical burns. Results An initial search retrieved 6493 articles, which was narrowed to 403 full-text articles that were reviewed independently by 3 of the authors and categorized. Of 202 included articles, there were 8 randomized controlled trials and 2 systematic reviews. Six evidence-based guidelines were reviewed. Referral of hand burns to specialist centers, use of telemedicine, early excision and grafting, and immediate static splintage have been recommended. Enzymatic debridement results in earlier intervention, more accurate burn assessment, preservation of vital tissue, and fewer skin grafts, and ideally requires regional anesthesia. Guidance on escharotomy emphasizes indication, technique and adequate intervention, and potential for enzymatic debridement. Inclusion of topical negative pressure, dermal regenerative templates, acellular dermal matrices, and noncellular skin substitutes in management has helped improve scar and functional outcomes. Discussion The results of this literature review demonstrate that multiple national and international societies have published burns guidelines during the decade studied, with aspects directly relevant to hand burns, including the International Society for Burn Injuries guidelines. There are opportunities for evidence-based quality improvement across the field of hand burns in many centers. Conclusions More than 200 articles globally in 10 years outline advances in the understanding of acute management of thermal hand burns. Incorporating the evidence base into practice may facilitate optimization of triage referral pathways and acute management for hand burns.
