Conventional supervised exercise programs (SEPs) for claudicants are traditionally based on time-constrained, group-based structured programs usually at a hospital site. Uptake of an SEP is poor, despite the high-level evidence demonstrating its clinical effectiveness; therefore, alternative forms of exercise programs are needed which are more acceptable to patients. This study aimed to explore a range of exercise modalities to determine patient preferences for exercise delivery on a national level. This was a questionnaire survey to identify and incorporate patient preferences when designing a multicenter nationwide health-service evaluation of patient preference to exercise in the United Kingdom's National Health Service (the PREFER study). Patients with documented stable intermittent claudication who were suitable for an SEP were given a questionnaire to fill out at their clinic visit. Data were recorded using the Bristol Online Survey tool (http://www.survey.bris.ac.uk/) and analyzed descriptively. Thirty complete questionnaires were analyzed. Participants were generally unilateral claudicants (80%) with symptoms for over 1 year (64%). Only 6 of the 30 patients had engaged in a lifelong routine of exercise. Eighty-seven percent of patients indicated that they had not taken part in an exercise program, but 73% of those indicated that they would be willing to participate to improve their walking. Most patients expressed a preference for a home exercise program (50%) followed by a hospital SEP. The majority of patients (43%) were happy to exercise 3 days per week using a walking-based program (53%). There was however no consensus on the duration or intensity of the exercise program. The SEP is the recommended first-line treatment for intermittent claudication patients; however, the vast majority of patients fail to engage with or complete an exercise program. This study demonstrates that exercise therapy should be individualized and take a patient-centered approach. Commissioning groups should incentivize hospitals and clinicians to engage with their patient populations to understand their needs and deliver an appropriate service.

A surgical site infection (SSI) may occur in up to 30% of procedures and results in significant morbidity and mortality. We aimed to assess the feasibility of conducting a randomised controlled trial (RCT) examining the use of dialkylcarbamoylchloride (DACC)-impregnated dressings, which bind bacteria at the wound bed, in the prevention of SSI in primarily closed incisional wounds. This pilot RCT recruited patients undergoing clean or clean-contaminated vascular surgery. Participants were randomised intraoperatively on a 1:1 basis to either a DACC-coated dressing or a control dressing. Outcomes were divided into feasibility and clinical outcomes. The primary clinical outcome was SSI at 30 days (assessed using Centers for Disease Control criteria and Additional treatment, Serous discharge, Erythema, Purulent exudate, Separation of the deep tissues, Isolation of bacteria and duration of inpatient Stay scoring methods). This study recruited 144 patients in 12 months at a median rate of 10 per month. Eligibility was 73% and recruitment 60%. At 30 days, there was a 36.9% relative risk reduction in the DACC-coated arm (16.22% versus 25.71%, odds ratio 0.559, P = 0.161). The number needed to treat was 11 patients. A large-scale RCT is both achievable and desirable given the relative risk reduction shown in this study. Further work is needed to improve the study protocol and involve more centres in a full-scale RCT.

BackgroundVaricose veins impair quality of life and can lead to chronic leg ulcers. National Institute for Health and Care Excellence (NICE) guidelines (CG168) set out evidence‐based standards for patient management. In England, Clinical Commissioning Groups (CCGs) fund NHS care within their locality. The objective of this study was to evaluate CCGs' commissioning policies and compare them with CG168.MethodsSearches were made for the published policies of all 206 English CCGs. They were reviewed for compliance with NICE guidelines and the associated quality standard. Areas of disagreement were analysed for themes.ResultsSome 203 CCGs (98·5 per cent) had a published policy and 190 (93·6 per cent) of these were published after publication of CG168. Only 73 of the policies (36·0 per cent) were compliant with CG168. Treatment was restricted on the basis of clinical disease severity in 119 CCGs (58·6 per cent); 29 (14·3 per cent) stipulated delay of treatment using a ‘trial’ of conservative treatment; 22 (10·8 per cent) used lifestyle‐related factors such as BMI and smoking status to ration treatment. Treatment was commissioned for uncomplicated symptomatic varicose veins in 87 CCGs (42·9 per cent), but some applied additional rationing mechanisms; 109 CCGs (53·7 per cent) would treat oedema, 183 (90·1 per cent) would treat skin and soft tissue damage, 202 (99·5 per cent) healed ulceration, and all would allow active ulcers to be treated.DiscussionThe majority of CCGs in England have commissioning policies that contradict NICE guidelines. Rationing strategies include disease severity, delay and patient lifestyle‐related factors, creating unwarranted geographical variation for varicose vein treatment, disregarding the NHS Constitution for England, and perhaps leading to an increase in costly treatment of chronic complications in the long term.
