How might the rapid development of artificial intelligence affect the delivery of UK Defence healthcare?

Artificial intelligence (AI) has developed greatly and is now at the centre of technological advancements. Current and recent military conflicts have highlighted the evolving complexity of warfare with rapid technological change at the heart of it. AI aims to understand and design systems that show signs of intelligence and are able to learn by deriving knowledge from data. There have been multiple AI-related developments in the medical field in areas such as diagnostics, triage, wearable technology and training with direct translations that may benefit UK Defence healthcare. With the increasing use of AI in society and medical practice, it is important to consider whether AI can be trustworthy and has any legal implications, and evaluate its use through an ethical lens. In conclusion, the rapid development of AI presents exciting opportunities for UK Defence to enhance its healthcare delivery.

Novel Management of a Femoral Fracture in Klippel-Trenaunay Syndrome.

Klippel-Trenaunay syndrome (KTS) is a rare congenital disorder with a clinical triad of capillary malformations, vascular abnormalities, and bone/soft tissue hypertrophy. This is the first case of closed femoral shaft fracture in a patient with KTS managed by flexible intramedullary nails. A 34-year-old patient sustained a right femoral mid-shaft spiral fracture after slipping on the grass. Due to a very narrow femur and large venous malformations, nail or plate fixation was impossible. Surgery was conducted using flexible intramedullary (TENS) nails with good reduction but significant bleeding which was controlled with tranexamic acid and CELOX. The patient required 4 units of red blood cells, 3 units of fresh frozen plasma, and 900 mL of cell saver intraoperatively with a further 2 units of RBC post-op. Fracture union was achieved 14 months after the initial fracture with additional pulsed ultrasound therapy. Bleeding from vascular malformations during surgery makes operative management challenging in KTS patients. Previous studies have reported a variety of management strategies to achieve fracture fixation and union including IM nailing, plate fixation, and external fixators, but encountered significant bleeding of up to 10 units and 15 units, respectively. Ultrasound therapy has been utilized as a useful adjunct in lower limb fracture with delayed therapy. Management of fractures in patients affected by KTS is extremely challenging despite extensive workup and planning to evaluate the optimal fixation method and explore strategies to reduce the risk of intra-operative bleeding. Management strategies should be tailored to the patient with close follow-up to assess fracture union.

Surgical management of a giant abdominal wall desmoid tumour.

Desmoid tumours are clonal fibroblastic proliferations in soft tissues, characterised by infiltrative growth and local recurrence, but not metastasis. Various treatment strategies for desmoid tumours exist, varying from observation, medical and systemic therapy to radiotherapy and surgery. A 25-year-old woman with a background of familial adenomatous polyposis was referred with an enlarging abdominal desmoid tumour measuring 40×40×40 cm despite repeated radiofrequency ablation, surgical debulking and hormone therapy. The patient had a two-stage operation. The first stage involved excision of the desmoid tumour with full-thickness abdominal wall. The abdominal wall was not closed, and a topical negative pressure seal was applied. After 2 days, she underwent the second stage: reconstruction of the abdominal wall defect with a large porcine mesh which was covered with anterolateral thigh flaps. Postoperative complications included ileus and a fall which required further surgery. The patient was discharged 1 month after the first operation. Abdominal MRI scans were performed at 3 and 7 months postdischarge and showed no recurrence of diseaseBackground.

Emergency general surgery 'Hot Clinic': Efficiency, prevention of hospital admissions and factors influencing patient experience.

OBJECTIVE: The constant pressure facing hospitals to reduce emergency inpatient admissions has led towards more consultant-led 'Hot Clinics' (HC). The patient experience in these settings remains poorly understood. This study evaluates the efficiency and ability of the HC to prevent unnecessary emergency surgical admissions and factors influencing the patient experience. METHODS: Patients were referred to the HC from the Emergency Department, General Practice or Out-of-Hours service over the initial six-week period. A questionnaire collected the reason for referral, management without a HC, final diagnosis and management. Appropriateness of referrals were evaluated by the HC consultant and retrospectively by a blinded consultant. A second questionnaire collected information on patient satisfaction in a subsequent study period. RESULTS: 119/126 referrals (94%) were judged appropriate in the HC analysis with 97/126 (77%) considered appropriate in the retrospective analysis. The HC reduced the amount of potential emergency surgical admissions from 114 to 14 (p < 0.001). In the second period, 114/121 patients (94%) rated the HC as very good or good; with privacy (p < 0.05) and decision-making (p < 0.001) linked to patient satisfaction. Comfort (p < 0.05) and decision-making (p < 0.001) were linked to patients recommending the service. 103 patients (85%) would be extremely, or very likely to recommend the HC service with 93 patients (77%) preferring HC treatment over a hospital admission. CONCLUSIONS: Most referrals to the HC were appropriate and it continues to prevent unnecessary emergency surgical admissions. The HC service is valued by NHS patients, who prefer HC treatment over admission. Various factors to improve the patient experience in HC have been identified.

What do adolescents want from their ED? An evaluation on the preferences and opinions of adolescents attending local EDs.

INTRODUCTION: The adolescent population comprises a significant proportion of attendances to the ED. Despite adolescent patients reporting lower levels of healthcare satisfaction compared with other age groups, their opinions are under-represented in existing literature. This prospective study investigated adolescents' expectations and preferences regarding the ED service. METHODS: A questionnaire designed by the investigators was distributed to children aged 12-16 years over a 6-month period in 2015 at two EDs in the UK. The questionnaire explored themes such as same-sex and similar-age areas, staff communication and environment. Interviews based on the questionnaire template were also conducted and guardians were permitted to accompany the participant. Verbal informed consent was obtained from both the young person and their guardian to participate in the study. RESULTS: There were 254 respondents, which represented 8.8% of adolescent attendances in the study period. 'Cleanliness' was rated the most important factor within the ED setting with 94.8% of respondents selecting 4 or 5 on a 5-point Likert scale. This was followed by 'feeling comfortable', 'clear explanation' and 'staff communication' (91.2%, 90.8% and 90.4% rating these 4 or 5, respectively). However, when participants were asked to select a single most important factor, being 'seen quickly' was selected most frequently (95/206, 46.1%). 'Entertainment' was regarded the least important with only 17.0% selecting 4 or 5 on the Likert scale. Preference for being treated in an adult ED compared with a child ED increased with age. CONCLUSIONS: Being 'seen quickly' was considered the single most important factor by adolescent patients in the ED. Notably, 'cleanliness' and aspects of communication also rated highly, with 'entertainment' regarded as least important. The additional insight into the healthcare preferences of the adolescent population provides a platform on which the future ED services can be tailored to the needs of young people.

Antihypertensive medication adherence in chronic type B aortic dissection is an important consideration in the management debate.

OBJECTIVE: Early aortic stenting in chronic type B aortic dissection (TBAD) may lead to long-term benefit, although the optimal treatment strategy is hotly debated. A robust comparison to outcomes seen in medically managed patients is challenging as the rate of antihypertensive medication adherence is unknown. The aims of this study were therefore to identify the rate of antihypertensive medication adherence and predictors of adherence in TBAD. METHODS: This was a cross-sectional mixed methods study of patients with TBAD. Medication adherence was assessed by the eight-item Morisky Medication Adherence Scale together with an assessment of demographic, behavioral, and psychological variables and disease-specific knowledge. RESULTS: There were 47 patients (mean age, 59 years; 81% male) who were recruited from a tertiary vascular unit. The mean total number of medications taken was 5.8 (2-14), and the mean number of antihypertensive medications was 1.9 (1-6). Of the 47 patients, 20 (43%) reported high levels of medication adherence, 17 (36%) reported moderate adherence, and 10 (21%) reported low adherence. Previous aortic surgery was associated with higher levels of adherence (ß = 0.332; P = .03), as was taking a greater number of medications (ß = 0.332; P = .026), perceived benefit from treatment (ß = 0.486; P < .001), good memory (ß = 0.579; P < .001), and low fears of side effects (ß = 0.272; P < .014). CONCLUSIONS: Medical management remains the mainstay of treatment in uncomplicated TBAD; however, the majority of patients are poorly adherent to their antihypertensive medications. The merits of thoracic endovascular aortic repair in TBAD are argued, and poor adherence is an important factor in the debate; one cannot robustly compare two strategies when half of a treatment group may not be receiving the stated intervention. To develop an evidence-based treatment strategy for TBAD, we must take into account the direct and indirect effects of medical therapy and thoracic endovascular aortic repair. Further work to improve medication adherence and to understand its impact on disease progression is vital to inform the debate and to deliver the best outcomes for patients.

Optical coherence tomography/scanning laser ophthalmoscopy imaging of optic nerve head drusen.

BACKGROUND AND OBJECTIVE: To evaluate optical coherence tomography/scanning laser ophthalmoscopy (OCT/SLO) imaging for optic nerve head drusen (ONHD). PATIENTS AND METHODS: Nine consecutive eyes with ONHD were imaged. Each underwent visual field testing, 20-MHz B-scan ultrasonography, photography, and OCT/SLO imaging of the nerve head. Similar evaluation was performed on 12 matched, disease-free control eyes for comparison. RESULTS: OCT/SLO imaging of ONHD demonstrated lucencies (100%), variable amounts of displacement, and thickening of the overlying nerve fiber layer, as well as disorganization of the adjacent retinal pigment epithelium (44%). Optic nerve head topography was measured (using horizontal and vertical electronic calipers). Mean disc diameter was 1.81 mm (range: 1.49 to 2.12 mm). All ONHD demonstrated anterior displacement of the base of the optic nerve cup (shallowing) compared to controls. The cup base was a mean +0.32 mm anterior to the retinal pigment epithelium for ONHD versus -0.23 mm for normal controls. CONCLUSION: OCT/SLO revealed unique and clinically helpful views of ONHD.

Effect of subconjunctival bevacizumab on primary pterygium.

PURPOSE: To investigate the effect of subconjunctival bevacizumab on primary pterygium. METHODS: A patient with an inflamed nasal primary pterygium, refractory to artificial tears and naphazoline, was enrolled in this study. After pretreatment with topical proparacaine and moxifloxacin, 0.05 mL of bevacizumab (1.25 mg/0.05 mL) was injected subconjunctivally at the limbus. Clinical signs of irritation, redness, and vascularization were monitored over 7 weeks. RESULTS: At 1 week postinjection, irritation and hyperemia showed near-total regression. At week 2, the pterygium maintained this appearance. By week 7, the degree of vascularity and symptoms of irritation had regressed to its preinjection state. CONCLUSIONS: Treatment of primary pterygium with subconjunctival bevacizumab results in a short-term decrease in vascularization and irritation. Further long-term studies should investigate the efficacy of bevacizumab as an adjunct to surgical excision or combined topical treatment targeting other growth factors involved in pterygium pathogenesis.

New-onset herpes simplex virus keratitis after cataract surgery.

We report the case of a 34-year-old man who had uncomplicated cataract surgery in his left eye. Medical history was significant for atopic dermatitis, requiring oral immunosuppressive medications. Two days after the surgery, the patient presented with pain, photophobia, decreased vision, and a small corneal abrasion. On postoperative day 5, the patient returned with left upper lid vesicular lesions and 2 corneal dendrites. Corrected vision was 20/100 OS, with intraocular pressure of 18 mm Hg and 1+ pigmented cells in the anterior chamber. Cultures of the lid lesions revealed herpes simplex virus (HSV) type 1. The patient was placed on oral acyclovir 800 mg 5 times a day. By day 8, the dendrites had resolved, and by day 15, the lid lesions healed over. HSV keratitis is an uncommon complication after cataract surgery. Ophthalmologists should be aware of the possibility of developing HSV keratitis even after the most routine cataract extraction.

Resources involved in managing retinal detachment complicated by proliferative vitreoretinopathy.

PURPOSE: To report the differences in cost of treatment and outcome in retinal detachment (RD) cases with and without proliferative vitreoretinopathy (PVR). METHODS: Analysis of clinical trial databases of RD observed in 190 eyes of 190 patients. Eyes were classified as no PVR, developing PVR, or established PVR. For each eye, total cost of treatment undertaken on Moorfields Eye Hospital vitreoretinal unit, final retinal status, and best-corrected visual acuity were recorded. RESULTS: Management of patients who developed PVR involved approximately double the resources of RD without PVR. Eyes with pre-exiting PVR had similar resource input to those with RD without PVR. Patients who developed PVR had a mean of 3.7 operations (including subsequent cataract surgery) compared to 1.8 and 2.1 respectively for noncomplicated RD and pre-existing PVR. Anatomic success and visual outcome was significantly worse in eyes with PVR. CONCLUSIONS: Treatment of eyes that developed PVR after initial surgery cost significantly more than eyes with no PVR or established PVR (P < 0.01). Improvements in the management of RD aimed at preventing PVR and advances in PVR treatment may have significant financial as well as clinical benefits.
