Effectiveness of Semiocclusive Sodium Carboxymethyl Cellulose Fibers and Hydrocolloid Dressings for Irritant Peristomal Dermatitis: A Case Series.

ABSTRACT: The most common complication in individuals with ostomies is irritant contact dermatitis from the acidic stoma effluent coming into contact with the peristomal skin. Although protective powders are widely used for the treatment of peristomal skin, there is little scientific evidence to justify their use. The combined use of sodium carboxymethylcellulose cellulose fibers (SCCFs) together with a hydrocolloid dressing for fixation is an effective alternative in the management of these wounds. Here, the authors report a case series of three patients presenting at a stoma therapy clinic with peristomal skin lesions because of severe irritant contact dermatitis. Patients were men aged between 70 and 81 years, had been diagnosed with colon cancer (n = 2) or bladder cancer (n = 1), and had undergone a colostomy (n = 1), ileostomy (n = 1), or Bricker-type ureteroileostomy (n = 1). A semiocclusive care protocol was applied in a moist environment using SCCF and an extrathin hydrocolloid adhesive dressing, and the collection device was secured using adhesive resin and an ostomy belt. The combined use of SCCF and hydrocolloid dressings provided beneficial results to treat the dermatitis, with reduced discomfort after 7 days and lesions healing within 4 weeks.

"Sandwich" wound dressing to reduce surgical site infections during sacrococcygeal surgery: A retrospective analysis.

OBJECTIVE: To explore whether the "sandwich" wound dressing method with a hydrocolloid dressing can effectively reduce surgical site infection rates in sacrococcygeal aseptic operations. METHODS: A retrospective cohort of patients with sacrococcygeal aseptic operations (class I incision category) from January 2017 to March 2018 were divided into intervention (sandwich dressing) and control groups (conventional dressing). The surgical site infections (SSI) rate, wound healing course, hospitalization time, and medical costs in the two groups were determined. To exclude the influence of other factors, operation time, blood loss, age, sex ratio, the distance of the incision from the distal edge to the anus, and initial defecation times were compared between the groups. RESULTS: The SSI rates and medical costs in the interventional group were significantly lower than the control group (0% vs 78.57%, P < 0.0001; 3.27 ±â€¯0.98 vs 5.83 ±â€¯1.66 ¥10,000, p < 0.0001). Hospitalization times were also lower in the intervention compared to the control group (17.05 ±â€¯4.77 vs 34.50 ±â€¯15.47 day, P = 0.001). CONCLUSIONS: The sandwich wound dressing method with a hydrocolloid dressing can effectively prevent SSI during sacrococcygeal aseptic surgery.

A recombinant human collagen hydrogel for the treatment of partial-thickness burns: A prospective, self-controlled clinical study.

INTRODUCTION: Allogeneic and xenogeneic skin are recognized as the best coverings for skin burn wounds, but currently face a supply shortage. To solve this problem, our research group developed a standardized manufactured hydrogel dressing based on a new type of highly bioactive recombinant human collagen. STUDY DESIGN: Prospective self-controlled trial. OBJECTIVE: To evaluate the efficacy and safety of recombinant human collagen hydrogel in the treatment of partial burn wounds to the skin compared to those of xenogeneic skin. METHODS: This study included twenty-one patients admitted to Shanghai Changhai Hospital within 48 h after receiving partial-thickness skin burns. The wounds were symmetrically separated along the axis and treated with recombinant human collagen hydrogel (RHCH) or a human-CTLA4-Ig gene-transferred pig skin xenotransplant. The condition of the wound surfaces was recorded on days 0 (of enrollment), 5, 10, 15, and 20, and bacterial drug sensitivity testing, hematuria examination, and electrocardiographic tests were conducted on days 0, 10, 20, or on the day of wound healing. RESULTS: There were no statistically significant differences in wound healing time between the two groups. The median number of days to healing was 11.00 ± 0.56 for xenogeneic skin vs. 11.00 ± 1.72 for RHCH. CONCLUSION: During the observation period, the therapeutic effect of the RHCH developed by our group on partial-thickness burn wounds was not significantly different from that of gene-transferred xenogeneic skin. Thus, our designed RHCH shows potential for clinical use to treat burn wounds on the skin.

In Vitro Characterization of Pressure Redistribution Among Commercially Available Wound Dressings.

OBJECTIVE: Recent clinical evidence has suggested that certain wound dressings may play a significant role in protocols to prevent or reduce pressure injury (PI) in patients at risk by modifying the pressure, friction, and shear forces that can contribute to PI. The aim of this study was to investigate the pressure reduction properties of commercially available wound dressings in vitro. METHODS: Using a standardized protocol (1.7 kg, 7.5-cm sphere), testing was performed in a controlled environment by the same clinician using a pressure mapping device (XSENSOR LX205; XSENSOR Technology Corporation, Calgary, Alberta, Canada) to measure and compare the pressure mitigation properties in a variety of wound dressings. RESULTS: A total of 13 different commercially available dressings were tested in triplicate for changes in pressure redistribution as compared with the control. One dressing demonstrated the greatest reduction of pressure forces (OxyBand PR; 50.33 ± 1.45 mm Hg) compared with the control (302.7 ± 0.33 mm Hg) and the greatest surface area of all the study dressings tested. There was a negative correlation (R2 = 0.73) between the average pressure distribution of a wound dressing and its contact area. Further, the peak pressure for OxyBand PR (P ≤ .05) was significantly different from all other tested dressings. CONCLUSIONS: One dressing (OxyBand PR) provided superior pressure redistribution and significantly reduced peak pressure in this study when compared with currently available standard foam and silicone dressings that are marketed for the purpose of PI prevention.

A bio-degradable synthetic membrane to treat superficial and deep second degree burn wounds in adults and children - 4 year experience.

INTRODUCTION: A new bio-degradable synthetic membrane was recently introduced to treat second degree burns in adults and pediatric patients. OBJECTIVE: To assess complications and outcomes using this absorbable synthetic membrane to treat second degree burns. METHODS: 229 burn patients, 138 pediatric, with superficial and deep second -degree wounds, treated with the absorbable synthetic membrane (Suprathel®, Polymedics, Denkendorf, Germany) were included in this study. Patients were treated under anesthesia or moderate sedation. The wound bed was prepared by using either rough debridement or dermabrasion excision. After hemostasis, the membrane was applied to the wound with an outer layer dressing of fatty gauze, bridal veil, absorptive gauze and an ACE® wrap. The outer dressing was removed every one to four days, depending on exudate, in order to closely follow the wound through the translucent membrane and fatty gauze layers. After complete epithelialization, the dressing separated and could be removed. The study focused on the need for subsequent grafting, healing time, patient pain level, hypertrophic scarring and rate of infection. RESULTS: All wounds in this study that were treated with Suprathel® healed without grafting. The average TBSA (Total Body Surface Area) was 8.9% (1%-60%). Average time to healing was 13.7 days for ≥ 90% epithelialization with 11.9 days for pediatric patients versus 14.7 days for adults. Throughout the treatment period, the average pain level was 1.9 on a 10-point scale. 27 patients developed hypertrophic scarring in some areas (11.7%). Average Length of stay (LOS) was 6.9 days. The rate of infection was 3.8% (8/229). Failure or progression to full thickness in part of the wounds was 5.2% (12/229). CONCLUSION: In treating second degree burn wounds, this membrane provides a simple, effective solution alternative with good outcomes and less pain than conventional and previously studied treatment options in the same institution. Fewer dressing changes and easier overall management of the wounds contribute to its favorable profile.

Clinical and Economic Impact of Wound Care Using a Polyurethane Foam Multilayer Dressing.

OBJECTIVE: To study the impact of a newly introduced dressing on efficiency and quality of care in routine clinical practice in a Spanish community setting. DESIGN AND SETTING: An ambispective multicenter observational study was conducted in 24 primary care centers and 6 nursing homes in 4 different Spanish regions. The study was carried out between November 2017 and March 2019. PATIENTS AND INTERVENTION: A total of 128 wounds in 94 patients (primary care, n = 79; nursing home, n = 15) were analyzed before and 4 weeks after switching to the study dressing. OUTCOME MEASURES: Frequency of dressing changes; secondary outcomes were change in the mean wound area and weekly cost and patient and provider satisfaction. MAIN RESULTS: The mean number of dressing changes was significantly reduced with the study dressing from 3.14 ± 1.77 changes per week to 1.66 ± 0.87 (P < .001), a 47.1% reduction in frequency. Wound area significantly reduced from 9.90 ± 19.62 cm to 7.10 ± 24.33 cm. In addition, a 58.7% reduction in weekly costs was achieved with the intervention. Patients and providers agreed that their satisfaction with wound care improved. CONCLUSIONS: The use of the study dressing in routine clinical practice could lead to a major improvement in both efficiency and quality of wound care. Its use could reduce wound care-related costs through improvements in healing and a reduced frequency of dressing changes. It also enhanced the wound care experience from the perspective of both patients and providers.

Highly Hydrophilic Polyurethane Foam Dressing Versus Early Hydrophilic Polyurethane Foam Dressing on Skin Graft Donor Site Healing in Patients with Diabetes: An Exploratory Clinical Trial.

OBJECTIVE: To compare the effects of early hydrophilic polyurethane (EHP) foam dressing and highly hydrophilic polyurethane (HHP) foam dressing on wound healing in patients with diabetes. METHODS: Twenty patients with diabetes with skin graft donor sites on the lateral thigh were enrolled in this study. Each donor site was divided into two equal-sized areas for the application of HHP or EHP foam dressing. The study endpoint was the time required for healing, defined as complete epithelialization of the donor site without discharge. All possible adverse events were also documented. MAIN RESULTS: Donor site healing was faster in 15 patients on the HHP half and 1 patient on the EHP half. In four patients, healing rates were the same between the HHP and EHP areas. Donor sites treated with HHP and EHP foam dressings healed in 17.2 ± 4.4 and 19.6 ± 3.7 days (P = .007), respectively. During the study period, no adverse event associated with the dressings occurred in either group. CONCLUSIONS: The HHP foam dressing might provide faster healing than EHP foam dressing for skin graft donor sites in patients with diabetes.

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.

Comparative efficacy of nine different dressings in healing diabetic foot ulcer: A Bayesian network analysis.

BACKGROUND: There is a wide variety of dressings currently available for the treatment of diabetic foot ulcers (DFUs). Because of a lack of evidence from head-to-head randomized controlled trials (RCTs), the relative effects of these dressings in DFU patients remain unclear. This study compared the efficacy of nine dressings in healing DFU. METHODS: A literature search was performed of the MEDLINE (PubMed), EMBASE and Cochrane Central Register of Controlled Trials (CENTRAL) databases. Reports published from 1993 to 2017 focusing on dressings for healing DFU were identified. RESULTS: Twenty-one RCTs, with a total of 2159 patients, were included in the present study. Bayesian network analysis showed that amniotic membrane dressings were superior to alginate, basic wound contact, foam, honey-impregnated, hydrocolloid, and iodine-impregnated dressings. Hydrogel dressings were better than basic wound contact dressings. Other dressings showed no significant differences. According to the probability of ranking results, amniotic membrane and hydrogel dressings are preferred for healing DFUs. CONCLUSIONS: The nine dressings evaluated in this study had different advantages in promoting the healing of DFU, but most differences among the dressings were not significant. According to the analysis of rank probability, amniotic membrane and hydrogel dressings are the most advantageous in terms of promoting DFU healing. It is recommended that the most suitable dressing should be selected taking into consideration exudate control, comfort, and cost.

Absorption Capacity of Wound Dressings: A Comparative Experimental Study.

In this study, absorption capacity of the most commonly used types of wound dressings was measured with an objective, quantifiable, and easily reproducible method. The use of objective measurements allowed us to perform an objective comparison of the capacity of the different types of dressings. An experimental study was performed, in which the absorptive capacity of polyurethane foams, alginate, hidrofiber, and hydrocolloid dressings was measured by using a methodology designed by the researchers. Polyurethane foams showed a higher absorption capacity than hidrofibers, alginates, and hydrocolloids when using a similar surface of dressing. A modification of dressing size after saturation was also observed, increasing its size in the case of foams and decreasing or maintaining it in the case of hidrofibers, alginates, and hydrocolloids. The results of this study show a better wound exudate management for polyurethane foams. However, when deciding which dressing to use for a specific wound, absorption capacity is not the only quality that should be taken into account, as other properties should also be considered.

A cost-effectiveness analysis of a hydration response technology dressing in the treatment of venous leg ulcers in the UK.

OBJECTIVE: Venous leg ulcers (VLUs) cause significant pain and suffering for patients. Additionally, they place considerable financial and service burden on the National Health Service (NHS). A large proportion of VLUs do not heal within the standard time frame of 16-24 weeks, resulting in static wounds which commonly have issues with increasing exudate production. As the NHS continues to face times of austerity, services need to find solutions to be able to reduce costs and release nursing time while maintaining standards of care. Cutimed Sorbion Sachet S, a hydration response technology dressing (HRTD), is a treatment option for the management of patients with a VLU. The objective of this study was to provide an update of the health economic analysis of HRTD in comparison with relevant comparators in the UK with current cost data. METHOD: HRTD was compared against four different dressings, Zetuvit Plus (a super absorbent polymer dressing SAP), DryMax extra (a superabsorbent dressing, SADM), KerraMax Care (superabsorbent dressing, SAKM) and Eclypse (superabsorbent dressing, SAE) from a cost-effectiveness perspective. Clinical data were derived from literature and expert opinion. Cost input was utilised based on publicly available data and literature. The average patient in the model is assumed to be 65 years with a diagnosed VLU. It is assumed that patients in the different treatment arms have the same background mortality, hence the endpoint mortality is not included in the model. The analysis is based on a deterministic Markov model derived from Harding et al. with weekly cycles. The following assumptions are made: first, all patients start in a static health state with a non-healed but non-progressing VLU. It is assumed in the model that patients wounds can transition to a deteriorating state or one where a wound is improving or could progress. Additionally, VLUs could be healed from a progressed wound (i.e. improved wound), or they could develop into a severe wound with complications (infections) to be treated in hospitals. The time frame for the analysis was fixed for one year and no re-occurence after healing was assumed to happen. RESULTS: The cost-effectiveness analysis demonstrates health economic dominance of HRDT being more effective and cost-saving against all analysed comparators. When using literature-based input values, the incrementally higher healing rates for HRDT are 11.04 months (versus SAP), 29.04 months (versus SADM), 1.68 months (versus SAKM) and 11.04 months (versus SAE). Cost savings per patient were £37.60 versus SAP, £171.68 versus SADM, £3.13 versus SAKM and £43.63 versus SAE. CONCLUSION: Clinical benefits and cost savings increase when real-life practice assumptions, based on expert opinion, are included. Based on the underlying health economic model, HRDT is more effective and less costly than other comparative products in VLUs in the UK.

Oxidized Regenerated Cellulose/Collagen Dressings: Review of Evidence and Recommendations.

OBJECTIVE: Healthcare systems are being challenged to manage increasing numbers of nonhealing wounds. Wound dressings are one of the first lines of defense in wound management, and numerous options exist. The oxidized regenerated cellulose (ORC)/collagen dressing may offer healthcare providers a robust and cost-effective tool for use in a variety of wounds. DESIGN: A multidisciplinary panel meeting was convened to discuss the use of ORC/collagen dressings in wound care and provide practice recommendations. A literature search was conducted to provide a brief review of the peer-reviewed studies published between January 2000 and March 2016 to inform the meeting. SETTING: A 2-day panel meeting convened in February 2017. PARTICIPANTS: Healthcare providers with experience using ORC/collagen dressings. This multidisciplinary panel of 15 experts in wound healing included podiatrists, wound care specialists (doctors, certified wound care nurses, and research scientists), and an orthopedist. RESULTS: The literature search identified 58 articles, a majority of which were low levels of evidence (69.3% were level 3 or lower). Panel members identified wound types, such as abrasions, burns, stalled wounds, diabetic foot ulcers, and pressure injuries, where ORC/collagen dressing use could be beneficial. Panel members then provided recommendations and technical pearls for the use of ORC/collagen dressings in practice. Barriers to ORC/collagen dressing use were discussed, and potential resolutions were offered. CONCLUSIONS: An ORC/collagen dressing can be a critical tool for clinicians to help manage a variety of wounds. Clinical and economic studies comparing standard-of-care dressings and plain collagen dressings to ORC/collagen dressings are needed.

A cost and clinical effectiveness analysis among moist wound healing dressings versus traditional methods in home care patients with pressure ulcers.

The aim of the study was a cost and clinical effectiveness analysis between moist wound healing dressings and gauze in a homecare set up for the treatment of stage III and IV pressure ulcers up to complete healing. In addition, we assessed the overall economic burden on the Healthcare System. Treatment method for each patient was chosen randomly by using sealed opaque envelopes. The authors monitored the healing progress and recorded treatment costs without interfering with the treatment process. The healing progress was estimated by using surface measurement transparent films. To estimate treatment costs, the authors took into account labor costs, cost of dressings, as well the cost of other materials such as cleansing gauzes, normal saline, syringes, examination gloves, antiseptics and adhesive tape. The patient group under treatment with moist wound healing dressings consisted of 27 men and 20 women aged 75.1 ± 8,6 and had an average ulcer surface of 43.5 ± 30.70 cm(2) ; the patient group under treatment with gauze comprised 25 men and 23 women aged 77.02 ± 8.02 and had an average ulcer surface 41.52 ± 29.41 cm(2) (p = 0.25, 95% CI, Student's t test). The average healing time for the moist wound healing dressings group' was 85.56 ± 52.09 days, while 121.4 ± 52.21 days for the "gauze group" (p = 0.0001, 95% CI, Student's t test). The dressing change frequency per patient was reduced in the "moist wound healing dressings group," 49.5 ± 29.61, compared with a dressing change frequency per patient of 222.6 ± 101.86 for the "gauze group" (p = 0.0001, 95% CI, Student's t test). The use of moist wound healing dressings had a lower total treatment cost of 1,351 € per patient compared with, the use of gauzes (3,888 €).

Hydrocolloid to prevent breakdown of nares in preterm infants.

PURPOSE: To determine if a double-barrier hydrocolloid dressing prevents trauma to the nares and columella in very low birthweight (VLBW) infants (<1,500 grams) receiving heated humidified high-flow nasal cannula (HHHFNC) oxygen. STUDY DESIGN AND METHODS: Retrospective two-group comparative study design. SAMPLE: Medical records (N = 53) of VLBW infants receiving HHHFNC were reviewed. Control infants (n = 27) did not have a double-barrier hydrocolloid dressing. Intervention infants (n = 26) had a double-barrier hydrocolloid dressing. Groups were similar on sex, race, birthweight, and gestational age. Control infants were significantly older than intervention infants at study entry (4.3 weeks and 1.5 weeks, respectively, p = .001). Skin condition of nares was scored daily ranging from 3 (no breakdown) to 9 (extensive breakdown). Skin scores were abstracted from medical records at baseline then weekly for comparison over time. RESULTS: There were no significant differences in skin scores between groups or over time. Week 1 mean skin score was 3.4 (±0.1) in both groups. Mean skin score at week 4 was 3.4 (±0.1) in Control infants and 3.1 (±0.08) in Intervention infants. CLINICAL IMPLICATIONS: HHHFNC is more frequently being used in infants of extreme prematurity. The dressing may have protected the more immature skin of the intervention infants; however, vigilant nursing observation of the infants' nares during HHHFNC cannot be ruled out. Nurses need adequate education on the consistent application of the hydrocolloid barrier and on documenting skin assessment scores each shift to promote skin protection in this vulnerable population.

Patient perceptions associated with the 5% lidocaine medicated plaster in daily practice.

OBJECTIVE: To evaluate patients' perceptions of 5% lidocaine medicated plaster for treatment of chronic neuropathic pain in daily clinical practice. RESEARCH DESIGN AND METHODS: In a prospective, multicentre, non-interventional observation, patient-reported outcome data were collected in clinical practices in Germany using the German Pain Questionnaire for pre-treatment documentation and the German Pain Diary for documentation of weekly treatment-associated changes. Questionnaires were completed by the patients without input from their physicians. MAIN OUTCOME MEASURES: Mean changes over the 12-week treatment period in pain intensity, in impairments of daily activities (modified pain disability index, mPDI) and of quality of life (quality of life impairment by pain inventory, QLIP), in Hospital Anxiety and Depression Scale scores (HADS-A and HADS-D), and in overall burden of pain. RESULTS: Data of 922 patients were evaluated. Mean average pain intensity over 24 h improved by 5.1 points (74%) from 6.9 ± 1.6 points at baseline. A 30% reduction in overall pain intensity was already observed within the first 2-3 weeks with continuous further reductions until end of observation. Marked improvements in anxiety and depression scores (40% and 52%, respectively), and in pain-related restrictions in daily life activities (66%) and quality of life (157%) were also noted. Burden of pain was reduced by 56.2 points (73%) from 77.5 points at baseline. Stratification by diagnosis showed a treatment effect of lidocaine plaster for all underlying conditions with highest treatment effects for diabetic polyneuropathy and postherpetic neuralgia. CONCLUSIONS: In a patient population where 46% of individuals already suffered from chronic to markedly chronic pain, patients perceive the 5% lidocaine medicated plaster as an efficacious topical treatment of chronic neuropathic pain in daily clinical practice. Strongest pain relief as well as associated improvements in pain-related restrictions were observed within the first five treatment weeks; however, beneficial effects continued until end of observation.

A new hydrocolloid dressing prevents surgical site infection of median sternotomy wounds.

PURPOSE: This prospective and semi-randomized study was conducted to clarify the effectiveness of a new hydrocolloid dressing placed over median sternotomy wounds using an occlusive dressing technique. METHODS: The subjects were 253 patients undergoing coronary artery bypass grafting (CABG), who were randomized to receive either the new hydrocolloid dressing (Karayahesive, n = 117) or a polyurethane foam dressing (Tegaderm plus Pad, n = 136) immediately after sternal wound closure. Karayahesive was left in place for 7 days, whereas the Tegaderm plus Pad was removed on postoperative day (POD) 2 and replaced with an adhesive wound dressing until POD 7. RESULTS: In the Karayahesive group, complete integrity of the wound was achieved in 91% of the patients, with an infection developing in 3.4%: as a superficial surgical site infection (SSI) in three and as a deep SSI in one. On the other hand, in the Tegaderm plus Pad group, an infection developed in 10.3% (14 patients) of the patients: as a superficial SSI in nine and as a deep SSI in five (P < 0.05). The total treatment costs from the application of the dressing until completion of treatment was 699 yen for the Karayahesive and 910 yen for the Tegaderm plus Pad (P < 0.001). CONCLUSIONS: The new hydrocolloid dressing, applied with an occlusive dressing technique to median sternotomy wounds, prevented SSI and was cost effective.

Occlusive vs gauze dressings for local wound care in surgical patients: a randomized clinical trial.

OBJECTIVE: To compare effectiveness and costs of gauze-based vs occlusive, moist-environment dressing principles. DESIGN: Randomized clinical trial. SETTING: Academic Medical Center, Amsterdam, the Netherlands. PATIENTS: Two hundred eighty-five hospitalized surgical patients with open wounds. INTERVENTION: Patients received occlusive (ie, foams, alginates, hydrogels, hydrocolloids, hydrofibers, or films) or gauze-based dressings until their wounds were completely healed. MAIN OUTCOME MEASURES: Primary end points were complete wound healing, pain during dressing changes, and costs. Secondary end point was length of hospital stay. RESULTS: Time to complete wound healing did not differ significantly between occlusive (median, 66 days; interquartile range [IQR], 29-133 days) and gauze-based dressing groups (median, 45 days; IQR, 26-106 days; log-rank P = .31). Postoperative wounds (62% of the wounds included) healed significantly (P = .02) quicker using gauze dressings (median, 45 days; IQR, 22-93 days vs median, 72 days; IQR, 36-132 days). Median pain scores were low and similar in the occlusive (0.90; IQR, 0.29-2.34) and the gauze (0.64; IQR, 0.22-1.95) groups (P = .32). Daily costs of occlusive materials were significantly higher (occlusive, euro6.34 [US $9.95] vs gauze, euro1.85 [US $2.90]; P < .001), but nursing time costs per day were significantly higher when gauze was used (occlusive, euro1.28 [US $2.01] vs gauze, euro2.41 [US $3.78]; P < .001). Total cost for local wound care per patient per day during hospitalization was euro7.48 (US $11.74) in the occlusive group and euro3.98 (US $6.25) in the gauze-based group (P = .002). CONCLUSIONS: The occlusive, moist-environment dressing principle in the clinical surgical setting does not lead to quicker wound healing or less pain than gauze dressings. The lower costs of less frequent dressing changes do not balance the higher costs of occlusive materials. Trial Registration trialregister.nl Identifier: 56264738.
