Impact of primary dressings on healing of venous leg ulcers: a French cohort study from the healthcare insurance database.

OBJECTIVE: Multicomponent bandages (MCBs) are recommended by the French Authority for Health (Haute Autorité de Santé) as first-line treatment for venous leg ulcers (VLUs). A first analysis of the data collected from the French administrative healthcare database (Système National des Données de Santé (SNDS)) on 25,255 patients with a VLU supported superiority of MCBs versus short stretch bandages when considering the healing outcomes and costs associated with closure of these wounds. The aim of this study was to assess how beneficial the primary dressing (technology lipido-colloid nano-oligosaccharide factor (TLC NOSF) or control dressing group (CDG)) could be, when used in combination with MCBs in the treatment of VLUs. METHOD: Data from the SNDS were collected for patients meeting the following inclusion criteria: treatment for a VLU with MCBs and with the same dressing type (TLC-NOSF or CDG) during the whole treatment period. Healing outcomes were documented on the global cohorts and propensity score-matched cohorts. The mean healthcare cost and the ecological impact were calculated for those patients healed within the study period. RESULTS: In total, 12,507 patients met the criteria for treatment with both MCBs and TLC-NOSF dressings (n=1134) versus MCBs and CDG (n=11,373); with 1134 and 2268 patients per group following propensity score matching. Healing outcomes were favourable for the TLC-NOSF group in the global cohort and were enhanced in the propensity score-matched cohorts. At every point of the analysis, the adjusted healing rates were significantly higher in the TLC-NOSF group than in the CDG group (p<0.001). In the propensity score-matched cohorts (n=3402), the healing rate at three months was 52% in the TLC-NOSF group versus 37% in the CDG group (p<0.001). The median healing time was 87 days versus 125.5 days in the TLC-NOSF and CDG groups, respectively (p<0.0001). TLC-NOSF dressings significantly reduced the average treatment cost per healed ulcer (€2099) by 23.7% compared with dressings without TLC-NOSF (€2751) (p<0.001), as well as the resources used. CONCLUSION: This SNDS analysis confirms, in the largest real-life study performed in VLU management, the superiority of the TLC-NOSF dressings versus those not impregnated with the NOSF compound. Better clinical outcomes associated with cost savings and a positive ecological impact support the combination of MCBs and TLC-NOSF dressings and should be considered as an optimal standard of care for the global management of VLUs. These outcomes reinforce the current positions of the international guidelines on the use of NOSF impregnated dressings (UrgoStart range; Laboratoires Urgo, France) in this pathology.

Improved Short-Term Prognosis of Pediatric Partial-Thickness Burns: Emergency Conservative Debridement Under Topical Anesthesia.

OBJECTIVES: Early wound management for pediatric patients with partial-thickness burns in the emergency department remains debatable. This study aims to evaluate the value of emergency conservative debridement under topical anesthesia in improving short-term prognosis of pediatric partial-thickness burns. METHODS: This retrospective cohort study enrolled children with partial-thickness thermal burns presenting to the emergency department within 6 hours postburn. All the enrolled patients were divided into 2 groups: the debridement group and the dressing group. The associations between emergency conservative debridement and time to reepithelialization was analyzed by using Kaplan-Meier curves with log rank test and multivariate Cox regression analysis. Moreover, the associations between emergency conservative debridement and in-hospital cost and length of stay were also evaluated. RESULTS: All baseline characteristics between groups were comparable (all P > 0.05). Emergency conservative debridement under topical anesthesia significantly decreased the median value of time to reepithelialization (13 vs 14 days, P = 0.02). Cox regression analysis showed that emergency conservative debridement significantly improved wound reepithelialization after adjusting for burn size (odds ratio, 4.07; 95% confidence interval, 1.64-10.11; P < 0.01). The mean length of stay of patients receiving conservative wound debridement was lower than that of patients in the wound dressing group (14.3 ± 7.3 vs 18.8 ± 10.4 days, P < 0.01), but not in terms of mean in-hospital cost per 1% total body surface area (2.8 ± 1.9 vs 3.0 ± 2.1 × 103 RMB per 1% total body surface area, P = 0.58). CONCLUSIONS: Emergency conservative debridement of pediatric partial-thickness burns under topical anesthesia significantly improves the wound healing outcomes without increasing health care burden.

Systematic review and quality assessment of clinical and economic evidence for superabsorbent wound dressings in a population with chronic ulcers.

Effective exudate management is key for optimal ulcer healing. Superabsorbent dressings are designed to have high fluid handling capacity, reduced risk of exudate leakage, fluid retention under compression, and to sequester harmful exudate components. This study aimed to systematically identify existing evidence for the clinical efficacy and cost-effectiveness of superabsorbent dressings for the treatment of moderate-to-highly exudating chronic ulcers of various etiologies. The aim is focused on examining the 'class' effect of all superabsorbers, not any particular dressing. Clinical and cost effectiveness systematic reviews were conducted, searching Embase, MEDLINE, the Cochrane Library, and the Cumulative Index to Nursing and Allied Health Literature. The Cost Effectiveness Analysis Registry and Econ papers were also searched for the economic review. Outcomes of interest included ulcer closure, dressing properties, hospital- and infection-related outcomes, safety, and economic outcomes. Fourteen studies were included in the clinical systematic review. Eleven were case series, with one randomised controlled trial, one retrospective matched observational study, and one retrospective cohort study. The studies investigated eight superabsorbent dressings and were heterogeneous in their patient population and outcomes. Superabsorbent dressings may result in favourable outcomes, including reductions in frequency of dressing change and pain scores. As most studies were case series, drawing firm conclusions was difficult due to absence of a comparator arm. The economic systematic review identified seven studies, five of which were cost-utility analyses. These suggested superabsorbent dressings are a more cost-effective option for the treatment of chronic ulcers compared with standard dressings. However, the small number and low quality of studies identified in both reviews highlights the need for future research.

Incisional negative pressure wound therapy for the prevention of surgical site complications in Paediatric patients with non-idiopathic scoliosis: A randomized clinical trial.

Surgical wound complications are adverse events with important repercussions for the health of patients and health system. Surgical site infections and wound dehiscences are among the most important surgical wound complications, with a high incidence in paediatric patients undergoing surgery for non-idiopathic scoliosis. Incisional negative pressure wound therapy for surgical incisions is used as a preventive measure against surgical wound complications in adults; however, there has been scant evidence for using it in children. The purpose of this study is to evaluate the cost-effectiveness of incisional negative pressure wound therapy in preventing surgical wound complications in paediatric patients undergoing surgery to treat non-idiopathic scoliosis. Randomized clinical trial. Children younger than 18 years of age undergoing surgery for non-idiopathic scoliosis were randomly assigned into two groups to receive one of two different types of dressings for the first 7 days after surgery. One group were treated with a postoperative hydrofibre and hydrocolloid dressing with silver for wounds (control group), and the other group received a single-use incisional negative pressure wound therapy system (intervention group). The wounds were assessed after removal of the dressings at 7 days after surgery and again at 30, 90, and 180 days after surgery. Surgical wound complications, sociodemographic variables, variables related to the procedure and postoperative period, economic costs of treatment of surgical wound complications, and time to healing of the surgical wound were recorded. Per protocol and per intention to treat analysis was made. The per protocol incidence of surgical wound complications was 7.7% in the intervention group versus 38.5% in the control group (p = 0.009; Fisher exact test. RR = 0.20 IC95%: 0.05-0.83). Surgical wound dehiscence, surgical site infections, seroma, and fibrin were the most common surgical wound complications. The type of surgery, duration of surgery, and patients' age were associated with a higher risk for surgical wound complications. Postoperative hydrofibre and hydrocolloid dressing with silver for wounds were found to be associated with a longer time to healing. Initial costs for dressings in the group receiving incisional negative pressure wound therapy were higher, but the total postoperative costs were higher for those receiving postoperative hydrofibre and hydrocolloid dressing with silver for wounds. It was found that for each US$1.00 of extra costs for using incisional negative pressure wound therapy, there was a benefit of US$12.93 in relation to the cost of complications prevented. Incisional negative pressure wound therapy is cost-effective in the prevention of surgical wound complications in children undergoing surgery for non-idiopathic scoliosis.

[Economic and clinical aspects of postoperative bandages selection: in search of the best solution]. / Ekonomicheskie i klinicheskie aspekty vybora posleoperatsionnykh povyazok: v poiskakh optimal'nogo resheniya.

OBJECTIVE: Investigation of the clinical and economic advisability of using self-adhesive wound bandages of plaster type (on the example of Cosmopor E steril) compared to gauze bandages in the conditions of medical organization. METHODS: Study design - a retrospective analysis of literature data. Methods of pharmacoeconomic analysis - cost minimization analysis, «impact on budget¼ analysis. The Unified Information System in Procurement was the information source of the self-adhesive bandages cost. The charges of gauze bandages production were calculated on the basis of data provided by structural subdivisions of SamSMU Clinics. RESULTS: It was determined that the use of self-adhesive bandages of plaster type is economically feasible as a result of the analysis of cost minimization and impact on the budget. Saving during 1 year can be from 259 466 to 532 603 rubles (in total for three departments - 1.1 million rubles). Sensitivity analysis showed the stability of the obtained results to the variation of entry conditions (costs for gauze bandages and bandages of plaster type) in a wide range of values. CONCLUSION: The data obtained from the study showed that the use of bandages of plaster type for different types of surgical treatment is more justified in terms of cost saving.

Single-use negative pressure wound therapy reduces costs in closed surgical incisions: UK and US economic evaluation.

OBJECTIVE: Single-use negative pressure wound therapy (sNPWT) following closed surgical incisions has a demonstrable effect in reducing surgical site complications (SSC). However, there is little health economic evidence to support its widespread use. We sought to evaluate the cost-effectiveness of sNPWT compared with standard care in reducing SSCs following closed surgical incisions. METHOD: A decision analytic model was developed to explore the total costs and health outcomes associated with the use of the interventions in patients following vascular, colorectal, cardiothoracic, orthopaedic, C-section and breast surgery from the UK National Health Service (NHS) and US payer perspective over a 12-week time horizon. We modelled complications avoided (surgical site infection (SSI) and dehiscence) using data from a recently published meta-analysis. Cost data were sourced from published literature, NHS reference costs and Centers for Medicare and Medicaid Services. We conducted subgroup analysis of patients with diabetes, an American Society of Anesthesiologists (ASA) score ≥3 and body mass index (BMI) ≥30kg/m2. A sensitivity analysis was also conducted. RESULTS: sNPWT resulted in better clinical outcomes and overall savings of £105 per patient from the UK perspective and $637 per patient from the US perspective. There were more savings when higher-risk patients with diabetes, or a BMI ≥30kg/m2 or an ASA≥3 were considered. We conducted both one-way and probabilistic sensitivity analysis, and the results suggested that this conclusion is robust. CONCLUSION: Our findings suggest that the use of sNPWT following closed surgical incisions saves cost when compared with standard care because of reduced incidence of SSC. Patients at higher risk should be targeted first as they benefit more from sNPWT. This analysis is underpinned by strong and robust clinical evidence from both randomised and observational studies.

Cost-effectiveness analysis of negative pressure wound therapy dressings after open inguinal vascular surgery - The randomised INVIPS-Trial.

AIM: While the scientific evidence in favour of negative pressure wound therapy (NPWT) dressings on sutured incisions in the prevention of surgical site infections (SSIs) has increased, the cost-effectiveness after vascular surgery has not been evaluated. The aim of this study was to evaluate the cost-effectiveness of NPWT compared to standard dressings for the prevention of SSIs after open inguinal vascular surgery. MATERIALS AND METHODS: Patient data were retrieved from the randomised INVIPS-trial's open arm, which included patients randomised to either NPWT or standard dressings. The patients were surveyed for SSIs for 90 days postoperatively. The patients' individual cost data were included and analysed from a healthcare perspective. The patients' quality of life was measured using the Vascuqol-6 questionnaire pre- and 30 days postoperatively. Cost-effectiveness of NPWT was determined by decreased or equal total costs and a significant reduction in SSI incidence. RESULTS: The mean vascular procedure-related costs at 90 days were €16,621 for patients treated with NPWT (n = 59) and €16,285 for patients treated with standard dressings (n = 60), p = 0.85. The SSI incidence in patients treated with NPWT was 11.9% (n = 7/59) compared to 30.0% (n = 18/60) with standard dressings, p = 0.015. This corresponds to an increased mean cost of €1,853 per SSI avoided. The cost-effectiveness plane of incremental vascular procedure-related costs and difference in Vascuqol-6 score showed that 42% of estimates were in the quadrant where NPWT was dominant. CONCLUSION: NPWT is considered cost-effective over standard dressings in patients undergoing open inguinal vascular surgery due to reduced SSI incidence at no higher costs.

A multilayer polyurethane foam dressing for pressure ulcer prevention in older hip fracture patients: an economic evaluation.

OBJECTIVE: Hospital-acquired pressure ulcers (PU) have a substantial negative impact on patients and continue to impose a cost burden on hospital providers. Since the incidence of fragility fracture is growing, driven by the increase in the older population, it is expected that the overall incidence of associated complications will also increase accordingly. The aim of this economic evaluation was to determine whether the use of a multilayer, silicone-adhesive polyurethane foam dressing (ALLEVYN LIFE, Smith & Nephew, UK) alongside standard prevention (SP) for the prevention of PUs in older patients with hip fractures is a cost-effective strategy, compared with SP alone. METHOD: A decision-analytic model was constructed to determine the incremental cost and effectiveness of the foam dressing strategy from the perspectives of the Italian and US hospital systems. We also performed one-way and probabilistic sensitivity analyses. RESULTS: The foam dressing intervention was found to be cost saving and more effective than SP in both Italy and the US. Switching to foam dressing and standard prevention would result in an expected cost saving of €733 per patient in Italy and $840 per patient in the US, reducing the per-patient cost of treating PUs by 37-69% and 36-68%, respectively. The one-way and probabilistic sensitivity analyses demonstrate that the strategy remains dominant over a range of values of the input variables. CONCLUSION: The foam dressing intervention is likely to be a cost-effective strategy compared with standard prevention alone.

Comparison of platelet-rich plasma gel in the care of the pressure ulcers with the dressing with serum physiology in terms of healing process and dressing costs.

This research was carried out with the aim of comparing the effects of platelet-rich plasma (PRP) gel and gas dressing with serum physiologic applied to stage II pressure ulcer in coccyx of patients for 2 months on healing process and dressing costs. This prospective randomised controlled experimental study was conducted with 60 patients hospitalised in the palliative care unit after surgery. The experimental group (n = 30) was dressed with platelet-rich plasma gel. The control group (n = 30) was treated with serum physiologic dressing. At the end of the 20th observation of the patients in the experimental group, it was found that the mean scores of area, exudate, and tissue type in pressure sores decreased statistically (P < .001). In the control group, no significant difference was found between the mean PUSH score at the end of the 20th observation (P > .05). The study showed that PRP gel had a positive effect on healing of stage II pressure ulcers with platelet-rich plasma gel dressings. In addition, when evaluated in the long term, it was concluded that platelet-rich plasma gel is easily accessible and less costly than serum physiological dressing.

Cost-effectiveness of incisional negative pressure wound therapy compared with standard care after caesarean section in obese women: a trial-based economic evaluation.

OBJECTIVE: To evaluate the cost-effectiveness of incisional negative pressure wound therapy (iNPWT) in preventing surgical site infection in obese women after caesarean section. DESIGN: A cost-effectiveness analysis conducted alongside a clinical trial. SETTING: Five obstetric departments in Denmark. POPULATION: Women with a pregestational body mass index (BMI) ≥30 kg/m2 . METHOD: We used data from a randomised controlled trial of 876 obese women who underwent elective or emergency caesarean section and were subsequently treated with iNPWT (n = 432) or a standard dressing (n = 444). Costs were estimated using data from four Danish National Databases and analysed from a healthcare perspective with a time horizon of 3 months after birth. MAIN OUTCOME MEASURES: Cost-effectiveness based on incremental cost per surgical site infection avoided and per quality-adjusted life-year (QALY) gained. RESULTS: The total healthcare costs per woman were €5793.60 for iNPWT and €5840.89 for standard dressings. Incisional NPWT was the dominant strategy because it was both less expensive and more effective; however, no statistically significant difference was found for costs or QALYs. At a willingness-to-pay threshold of €30,000, the probability of the intervention being cost-effective was 92.8%. A subgroup analysis stratifying by BMI shows that the cost saving of the intervention was mainly driven by the benefit to women with a pre-pregnancy BMI ≥35 kg/m2 . CONCLUSION: Incisional NPWT appears to be cost saving compared with standard dressings but this finding is not statistically significant. The cost savings were primarily found in women with a pre-pregnancy BMI ≥35 kg/m2 . TWEETABLE ABSTRACT: Prophylactic incisional NPWT reduces the risk of SSI after caesarean section and is probably dominant compared with standard dressings #healtheconomics.

Cost-effectiveness of a bacterial-binding dressing to prevent surgical site infection following caesarean section.

OBJECTIVE: A randomised controlled trial (RCT) recruited women undergoing caesarean section (CS) in Poland. The aim of the trial was to assess the efficacy of a dialkylcarbamoyl chloride (DACC)-impregnated surgical dressing (bacterial-binding dressings) compared with standard of care (SoC) in preventing surgical site infection (SSI). The aim of the present analysis was to evaluate the cost-effectiveness of the bacterial-binding dressings in the context of the UK National Health Service (NHS). METHOD: The clinical trial randomised patients to a bacterial-binding dressing (n=272) or a standard surgical dressing (n=271). The study recorded the presence of SSI and associated resource use up to 14 days postoperatively. To generalise results to the NHS, UK unit costs were applied to resource use recorded in the trial. An alternative approach applied a single UK-specific episode cost per SSI. RESULTS: There were 543 women recruited to the trial. SSI rates were 5/272 (1.8%) and 14/271 (5.2%) for bacterial-binding dressings and SoC, respectively (p=0.04). Patients in the bacterial-binding dressing group had six fewer outpatient visits and 33 fewer hospital bed-days. The mean length of SSI-attributable hospitalisation was 2.36 days. Applying UK unit costs at 2017 prices to resource use recorded in the trial, costs of SSI prophylaxis and treatment were £48.97 and £24.69 per patient in the SoC and bacterial-binding dressing groups respectively, a difference of £24.27 (49.6%) per patient. The alternative costing approach produced a cost saving of £119 (57.6%) per patient with the bacterial-binding dressing. CONCLUSION: Use of bacterial-binding dressings following CS has the potential to reduce the incidence of SSI and costs to the NHS.

Improving the Quality of Chronic Wound Care Using an Advanced Wound Management Program and Gentian Violet/Methylene Blue-Impregnated Antibacterial (GV/MB) Dressings: A Retrospective Study.

INTRODUCTION: Comprehensive wound management programs that employ a standardized integrated care bundle (ICB) and advanced wound dressings are generally recognized to decrease healing times and treatment costs. The purpose of this study was to compare wound healing rates and cost efficiencies as measured by nursing-care requirements for patients not on an ICB versus patients on an ICB and using a gentian violet/methylene blue-impregnated (GV/MB) antimicrobial advanced wound dressing. MATERIALS AND METHODS: The comprehensive wound management programs enabled continuous, standardized measurement of each patient's wound episode from admission with a wound to healing and discharge. Data was recorded over 24 months from 2016 to 2018. The variables recorded for each patient included: wound healing time (number of weeks), wound acuity based on the Bates-Jensen Wound Assessment Tool (BWAT), a comorbidity index (using the Charlson Comorbidity Index), and the number of wound dressing changes. The wound dressing changes required a visit by a registered nurse and, therefore, served as an indicator of care delivery costs where the dressing change visit cost was $68 (CAD). RESULTS: A total of 6300 patients (25% of the total study population) were identified as using GV/MB dressings within the context of an ICB. The mean healing time for these patients was accelerated more than 50% versus patients not on an ICB. The average total cost of patient care was reduced by more than 75% from diagnosis to wound healing when patients were on an ICB with GV/MB dressings. These results compared well to patients on ICBs that had other types of advanced dressings. CONCLUSION: The study demonstrates that a comprehensive wound management program based on integrated care bundles in conjunction with GV/MB dressings can be a highly-effective clinical option. The benefits showed significant reductions in healing times and treatment costs.

A Comparison of Three Dressing Methods for Pilonidal Sinus Surgery Wound Healing.

OBJECTIVE: To evaluate the effect of different dressing methods on the wound healing process after pilonidal sinus surgery. METHODS: In this clinical trial, 60 patients undergoing pilonidal sinus surgery were randomly assigned to one of three groups. In the first group, hydrogel or alginate and hydrocolloid compounds were used as a standard occlusive dressing method. A modified dressing method was used for the second group, in which transparent hydrocolloid films were replaced by Vaseline gauze. The third group was treated using gauze swabs soaked in normal saline. The length and depth of the studied wounds were recorded once a week for a month. During dressing changes, patient pain was recorded using an 11-point numeric rating scale. The collected data were analyzed by descriptive and inferential statistical methods. RESULTS: There was a significant reduction in wound length after 2 weeks in all three groups (P < .05), and the pain experienced by the first and second groups was significantly lower than the third group. However, the modified method used for the second group was associated with a lower cost. CONCLUSIONS: Considering the beneficial results of using modern dressings for wound healing and reducing the severity of associated pain, providers may want to consider using modified wound dressings after pilonidal sinus surgery. Study authors recommend that providers receive training on how to use these products.

Five-layer border dressings as part of a quality improvement bundle to prevent pressure injuries in US skilled nursing facilities and Australian nursing homes: A cost-effectiveness analysis.

The BORDER III trial found that five-layer silicone border dressings effectively prevented pressure injuries in long-term care, but the value of this approach is unknown. Our objective was to analyse the cost-effectiveness of preventing facility-acquired pressure injuries with a quality improvement bundle, including prophylactic five-layer dressings in US and Australian long-term care. Markov models analysed the cost utility for pressure injuries acquired during long-term care from US and Australian perspectives. Models calibrated outcomes for standard care compared with a dressing-inclusive bundle over 18 monthly cycles or until death based on BORDER III outcomes. Patients who developed a pressure injury simulated advancement through stages 1 to 4. Univariate and multivariate probabilistic sensitivity analyses tested modelling uncertainty. Costs in 2017 USD and quality-adjusted life years (QALYs) were used to calculate an incremental cost-effectiveness ratio (ICER). Dressing use yielded greater QALYs at slightly higher costs from perspectives. The US ICER was $36 652/QALY, while the Australian ICER was $15 898/QALY, both of which fell below a willingness-to-pay threshold of $100 000/QALY. Probabilistic sensitivity analysis favoured dressings as cost-effective for most simulations. A quality improvement bundle, including prophylactic five-layer dressings, is a cost-effective approach for pressure injury prevention in all US and Australia long-term care residents.

[A Noval Method for Producing Antibacterial Wound Dressing by Using Fused Deposition Molding with Post-3D-printed Process].

Using three-dimensional printing to produce antibacterial wound dressing is a new topic that will change the production style of wound dressing industry. Combining with post-3D-printed process, a desktop fused deposition molding equipment can be used to produce wound dressing containing polyvinyl alcohol, alginate and chitosan. The wound dressing produced by FDM has good aspects of absorbency, moisture vapour transmission rate and mechanical property. After loaded with antibacterial agent iodine and silver nano particle, the antibacterial activity rate increases to 99% and it is suitable to use as antibacterial wound dressing. This method affects the production of wound dressing to a more cost-effective way, and provides a possible individualized treatment for patient in the future.

Potential cost-effectiveness of using a collagen-containing dressing in managing diabetic foot ulcers in the UK.

OBJECTIVE: To estimate whether a collagen-containing dressing could potentially afford the UK's National Health Service (NHS) a cost-effective intervention for the management of diabetic foot ulcers (DFUs). METHOD: A decision model depicting the management of a DFU was constructed and populated with a combination of published clinical outcomes, resource use estimates and utilities for DFUs. The model estimated the incremental cost-effectiveness of a collagen-containing dressing plus standard care compared with standard care alone over a period of four months in terms of the incremental cost per quality-adjusted life year (QALY) gained. RESULTS: Treatment of DFUs of >6 months duration with a collagen-containing dressing plus standard care instead of standard care alone is expected to increase the probability of healing from 0.08 to 0.53 by four months and increase health-related quality of life at four months from 0.156 to 0.163 QALYs per patient. Additionally, treatment with a collagen-containing dressing has the potential to reduce management costs by 22% over four months when compared with standard care alone (from £2897 to £2255 per patient). Treatment of new DFUs with a collagen-containing dressing plus standard care instead of standard care alone was also found to improve outcomes for less cost. CONCLUSION: Within the study's limitations, use of a collagen-containing dressing plus standard care instead of standard care alone potentially affords the NHS a cost-effective (dominant) treatment for both non-healing and new DFUs, since it improves outcomes for less cost. Hence, protocols should be established which enable clinicians to effectively introduce collagen-containing dressings into care pathways and monitor response to treatment.

Epidermolysis bullosa: management complexities for paediatric patients.

The genetic skin condition, epidermolysis bullosa (EB) causes the skin to be fragile and blister. As a result, blisters need to be lanced and the skin needs to be dressed with specialist dressings for protection and to promote wound healing. METHOD: a prospective case series and product evaluation of the Allevyn™ Gentle Border Lite dressing range was conducted, with four paediatric patients diagnosed with the following types of EB: recessive dystrophic (generalised severe), dominant dystrophic, simplex (generalised severe) and junctional (localised). Specialist EB nurses at Birmingham Children's Hospital conducted the evaluation and compiled the case series. Management and outcomes: clinical, patient and health economic outcomes were captured. The outcomes reported suggest an increase in dressing time wear and a reduction in dressing changes when comparing Allevyn Gentle Border Lite dressings to the patient's regular foam dressing regime. Furthermore, a cost saving measure could be shown. CONCLUSION: this small case series suggests that the use of the Allevyn Gentle Border Lite dressing range can positively impact the clinical, patient and health economic outcomes of paediatric EB patients.

Economic case for intraoperative interventions to prevent surgical-site infection.

BACKGROUND: Surgical-site infection (SSI) occurs in 1-10 per cent of all patients undergoing surgery; rates can be higher depending on the type of surgery. The aim of this review was to establish whether (or not) surgical hand asepsis, intraoperative skin antisepsis and selected surgical dressings are cost-effective in SSI prevention, and to examine the quality of reporting. METHODS: The authors searched MEDLINE via Ovid, CINAHL via EBSCO, Cochrane Central and Scopus databases systematically from 1990 to 2016. Included were RCTs and quasi-experimental studies published in English, evaluating the economic impact of interventions to prevent SSI relative to surgical hand and skin antisepsis, and wound dressings. Characteristics and results of included studies were extracted using a standard data collection tool. Study and reporting quality were assessed using SIGN and CHEERS checklists. RESULTS: Across the three areas of SSI prevention, the combined searches identified 1214 articles. Of these, five health economic studies evaluating the cost-effectiveness of selected surgical dressings were eligible. Study authors concluded that the interventions being assessed were cost-effective, or were potentially cost-saving. Still, there is high uncertainty around the decision to adopt these dressings/devices in practice. The studies' reporting quality was reasonable; three reported at least 15 of the 24 CHEERS items appropriately. Assessment of methodological quality found that two studies were considered to be of high quality. CONCLUSION: With few economic studies undertaken in this area, the cost-effectiveness of these strategies is unclear. Incorporating economic evaluations alongside RCTs will help towards evidence-informed decisions.

Cost-effectiveness analysis of single-use negative pressure wound therapy dressings (sNPWT) to reduce surgical site complications (SSC) in routine primary hip and knee replacements.

We sought to evaluate the cost-effectiveness of single-use negative pressure wound therapy in patients undergoing primary hip and knee replacements using effectiveness data from a recently completed non-blinded randomized controlled trial. A decision analytic model was developed from UK National Health Service perspective using data from a single-centre trial. 220 patients were randomized to treatment with either single-use negative pressure wound therapy or standard care i.e., film dressings of clinician choice and followed for 6 weeks. Outcomes included dressing changes, length of stay, surgical site complications, cost and quality adjusted life years. The randomized controlled trial reported a reduction in dressing changes (p = 0.002), SSC (p = 0.06) and LOS (p = 0.07) in favor of single-use negative pressure wound therapy compared with standard care. The model estimated 0.116 and 0.115 QALY gained, 0.98 and 0.92 complications avoided for single-use negative pressure wound therapy and standard care, respectively. The cost/patient was £5,602 ($7,954) and £6,713 ($9,559) for single-use negative pressure wound therapy and standard care respectively resulting in cost-saving of £1,132 ($1,607) in favor of single-use negative pressure wound therapy. Greater savings were observed in subgroups of higher risk patients with BMI ≥ 35 and ASA ≥ 3 i.e., £7,955 ($11,296) and £7,248 ($10,293), respectively. The findings were robust to a range of sensitivity analyses. In conclusion, single-use negative pressure wound therapy can be considered a cost saving intervention to reduce surgical site complications following primary hip and knee replacements compared with standard care. Providers should consider targeting therapy to those patients at elevated risk of surgical site complications to maximize efficiency.

Evidence generation for wound care dressing selection: reviewing the issues.

In the UK, dressings are categorised as medical devices and manufacturers only have to provide limited evidence of effectiveness before dressings are used in clinical practice. Therefore, evidence based on clinical trial methods is scant. As a direct result, governing bodies in the UK are now recommending that decisions to select one dressing over another could mainly be made on price. Placed within the movement critiquing evidence-based practice (EBP), this paper summarises the main issues surrounding the generation of evidence in selecting dressings for wound care, which is immersed in a context that lacks resources, legislative clarity and freedom to choose methodological alternatives. Dressings are therapeutic medical devices rather than consumables and any rationalisation based on costs may have far-reaching implications for wound care clinicians through purchasing decisions and thus may limit their ability to manage wounds effectively.
