Pressure-Measuring Devices for Compression Therapy in Venous Leg Ulcers: A Comprehensive Review.

OBJECTIVE: To investigate the evolution of pressure-measuring devices used in compression treatment for venous leg ulcers and assess the most practical and effective devices to determine optimal pressure in compression therapy. DATA SOURCES: Relevant information was retrieved from databases including Google Scholar, PubMed, Wiley Online, and ScienceDirect without publication date restrictions. The keywords included venous leg ulcer, compression therapy, pressure measuring device, pressure sensor, and wireless system. STUDY SELECTION: Studies included in the review had to be published in English and discuss or compare pressure-measuring devices/sensors for compression therapy, the development of alternative sensors, and the applications of wireless technologies. Veterinary studies, conference proceedings, and unpublished articles were excluded. Applicable studies and articles were critically evaluated and synthesized. DATA EXTRACTION: After abstract review, 39 studies were identified. During full-text review, study details were collected using a data extraction form and organized into tables. Device attributes, accuracy, price, and limitations were categorized and analyzed. DATA SYNTHESIS: Studies disagree on the effectiveness and user-friendliness of existing pressure-measuring devices. These devices often impact user comfort and convenience, which are crucial factors in the adoption and use of wearable devices. Potential solutions for pressure-measuring devices with promising technologies were proposed: four feasible alternative sensors are described that could improve comfort and facilitate prolonged use under bandages. Advanced communication technologies may provide more convenience for users and practitioners. CONCLUSIONS: Conventional pressure-measuring devices used in compression therapy are not designed for the user's comfort and convenience. The use of flexible and stretchy pressure sensors (e-skin) provides good biocompatibility, conformability, and comfort and when integrated with near-field communication technology could address the drawbacks of current pressure-measuring devices.

Ex vivo comparison of the bursting strength of an equine ventral midline celiotomy covered by two standard abdominal bandages.

OBJECTIVE: To determine the compressive effect of abdominal bandages after ventral midline celiotomy closure in horses. STUDY DESIGN: Ex vivo, experimental study. ANIMALS: Equine cadavers (n = 18), six per group. METHODS: A 20-cm ventral midline celiotomy was created in each of 18 equine cadavers. A 200-L inflatable bladder was placed in the abdomen, and the linea alba was apposed. Horses were randomly assigned to no bandage (C), elastic (E), or Velcro inelastic (I) bandage groups for testing. Circumferential bandages were placed with a subbandage pressure monitoring system over the incision. The bladder was insufflated until construct failure, which was determined by a decrease in pressure reading. Bursting pressure, location of body wall or bandage failure, and subbandage pressures were recorded. RESULTS: Maximum bursting pressure was different between groups E and C (P = .004), with no difference between groups E and I (P = .146) or I and C (P = .085). Group I achieved higher subbandage pressure compared with group E (P = .036). Abdominal compliance was not different between groups (P = .099). Location of failure differed between groups (P = .011), with failure at the diaphragm more common in group I (6/6, 100%) compared with groups E (3/6 [50%]) and C (1/6 [16.7%]). CONCLUSION: Elastic abdominal bandages had higher abdominal bursting pressures compared with unbandaged incisions.

Efficacy of Absorbable Steroid-Impregnated Nasal Packing in Functional Endoscopic Sinus Surgery for Chronic Rhinosinusitis: A Systematic Review.

OBJECTIVE: To evaluate the efficacy of absorbable steroid-impregnated nasal packing on postoperative outcomes following functional endoscopic sinus surgery (FESS) for chronic rhinosinusitis (CRS). METHODS: A systematic review of the literature was conducted as per Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Twelve databases (including Journals@Ovid, Embase®, Medline®, EBM Reviews and Joanna Briggs Institute EBP Database) were searched using relevant keywords and expanded with corresponding MeSH/Emtree terms. Results were narrowed to English articles assessing the efficacy of absorbable packing impregnated with steroids post-production placed at time of surgery under general anesthetic, with hollow-lumen devices and devices inserted in-office excluded. RESULTS: Eight studies met criteria and were included in this review. Five evaluated the efficacy of the intervention in only CRS with nasal polyposis (CRSwNP) patients, two included all subtypes of CRS, and one included only CRS without nasal polyposis (CRSsNP). Of the eight studies, four studied the efficacy of Nasopore®, three studied bioabsorbable gels, and one studied bioabsorbable calcium alginate. Four studies applied triamcinolone as the operative steroid, with the other studies utilizing betamethasone, budesonide, mometasone, and dexamethasone. Seven studies demonstrated statistically significant improvements in endoscopic outcomes using validated scoring scales, albeit at differing timepoints. The one study which included only CRSsNP patients failed to find a significant difference. CONCLUSION: Steroid-impregnated nasal packing appears to have positive effects on postoperative endoscopic outcomes in CRSwNP patients undergoing FESS. Additional research is needed to evaluate the efficacy of these interventions in more recently defined subtypes of CRS, and whether these interventions differ in their efficacy in eosinophilic and non-eosinophilic CRS.

Healing Rates of Venous Leg Ulcers Managed With Compression Therapy: A Secondary Analysis of Data.

PURPOSE: The purpose of this study was to explore average time to heal for patients with venous leg ulcers (VLUs) receiving standard of care that included compression and advanced wound dressings. DESIGN: Secondary analysis of an existing electronic database. SUBJECT AND SETTINGS: A convenience sample consisting of 1323 patients with VLUs from various community care sectors (homecare and clinics) across Canada. METHODS: The Wound Studies database used in the analysis consisted of data from 6 studies conducted prospectively between 1999 and 2009 in which the treatment and delivery of care for all lower leg ulcers (venous, arterial, and mixed) in Canada was examined. From these studies, only patients with VLUs, with an ankle-brachial pressure index of greater than 0.8, and surface area measurements of the ulcers at baseline, 3 months, and 6 months were included. Descriptive statistics were used to determine the proportion of patients who achieved closure at 3 and 6 months and explore the weekly and monthly healing rates for those who did and did not achieve closure. Logistic regression analysis was performed to identify predictive factors for healing. RESULTS: A total of 777 patients (mean age 69 years) met inclusion criteria. The proportion of patients who achieved closure at 3 and 6 months was 42.2% and 48.6%, respectively. Of the participants who achieved wound closure, monthly mean healing rate, measured by percentage of reduction in surface area, was 33.4% (0.56 cm, SD 1.4 [median 0.15 cm]) through month 3, and 31.0% (0.70 cm, SD 1.6 [median 0.08 cm]) through month 6. The overall monthly surface area reduction was 30%. CONCLUSION: Study findings suggest a monthly surface area reduction of 30% provides a baseline healing rate for VLUs managed with compression therapy and advanced dressings. Findings also suggest standard of care is not sufficient for healing in over 50% of the population, as the proportion of those who achieved closure at 3 and 6 months was 42.2% and 48.6%, respectively.

Elastic Bandage vs Hypertonic Albumin for Diuretic-Resistant Volume-Overloaded Patients in Intensive Care Unit: A Propensity-Match Study.

OBJECTIVE: To compare elastic bandage (EB) vs hypertonic albumin solution administration to increase fluid removal by enhancing loop diuretic efficiency (DE) in patients with volume overload and diuretic resistance. PATIENTS AND METHODS: In this historic cohort study with propensity matching, we included diuretic-resistant adult (≥18 years) patients with volume overload after fluid resuscitation admitted in the intensive care unit from January 1, 2006, through June 30, 2017. Regression models and propensity matching were used to assess the associations of these interventions with changes in DE and other clinical outcomes. RESULTS: Of 1147 patients (median age, 66; interquartile range [IQR], 56-76 years; 51% [n=590] men), 384 (33%) received EB and 763 (67%) received hypertonic albumin solution. In adjusted models, EB was significantly associated with higher DE compared with hypertonic albumin solution (odds ratio, 1.37; 95% CI, 1.04 to 1.81; P=.004). After propensity matching of 345 pairs, DE remained significantly different between the 2 groups (median, 2111; IQR, 1092 to 4665 mL for EB vs median, 1829; IQR, 1032 to 3436 mL for hypertonic albumin solution; P=.02). EB, male sex, lower baseline serum urea nitrogen level, lower Charlson Comorbidity Index score, and higher baseline left ventricular ejection fraction were DE determinants. The lowest DE quartile (<1073 mL/40-mg furosemide equivalent) following adjustment for known predictors of mortality remained independently associated with higher 90-day death rate (odds ratio, 1.64; 95% CI, 1.13 to 2.36; P=.009). CONCLUSION: EB use is associated with greater DE than hypertonic albumin solution during the deescalation phase of sepsis resuscitation. Prospective clinical trials would validate the findings of this hypothesis-generating study.

Implementing a Wearable Sensor for Lymphedema Garments: A Prospective Study of Training Effectiveness.

Lymphedema garments apply therapeutic pressure to maintain minimum leg volume. Practitioners and patients apply these garments and seek to achieve appropriate compression pressure "by feel." PURPOSE: A study was conducted to assess the feasibility of applying a sensor-feedback device to train staff to accurately apply garments. METHODS: A convenience sample of wound care and rehabilitation staff volunteered for a prospective, randomized, unblinded, single-center pilot study. Participants were randomized to instruction+feedback (ie, receiving training on compression application and using the device to determine whether they achieved desired pressure) or instruction only groups (n = 6 each). Each volunteer applied hook-and-loop closures on the author's leg pre- and post-training with a target of 35 mm Hg, or |Ppre- 35|= |Ppost- 35|=0. (|P| is absolute value of P). The feedback group used a device to measure the applied compression; the device consists of a capacitive sensor of thin polyurethane foam between conductive fabric layers and a microcomputer/Bluetooth transmitter under a vacuum seal that fits into a fabric pocket of a lymphedema garment at the posterior ankle and pairs with a mobile device. A lymphology-certified therapist coordinated training. Data were collected with a pen/paper tool and analyzed with Student's t test. RESULTS: The instruction+feedback group was closer to target after training (|Ppre - 35|= 10 ± 12 mm Hg; |Ppost - 35|=5 ± 4 mm Hg; P <.05; paired t test) than the instruction only group (|Ppre- 35|=19 ± 11 mm Hg; |Ppost - 35|=12 ±12 mm Hg; not significant). CONCLUSION: This wearable mobile pressure sensor device assists practitioners in applying hook-and-loop lymphedema garments closer to target pressure. Larger studies with clinicians and research that involves patient application of compression are warranted.

Management of people with venous leg ulcers by Australian general practitioners: An analysis of the national patient-encounter data.

Venous Leg Ulcers cost Australia's healthcare system millions yearly, as they are underdiagnosed, and possibly undertreated. Most Venous Leg Ulcers are seen in general practice. However, it is currently unknown as to what treatment actions are most common in these contexts. Understanding how they are managed in these settings can improve healthcare delivery and patient outcomes. Using cross-sectional general practitioner patient encounter data collected April 2006 to March 2016 from the Bettering the Evaluation and Care of Health program, a continuous national study of general practice clinical activity in Australia, we aimed to describe the characteristics of venous leg ulcer management by general practitioners in Australia. Among the 972 100 general practitioner-patient encounters recorded, 3604 (0.34%) involved management of VLU. Male general practitioners managed Venous Leg Ulcers significantly more often than female general practitioners. Most Venous Leg Ulcers were treated via dressings (76%) and/or pharmacological treatments (25.7%), with few patients receiving the best practice treatment of medical compression (2.1%) or referral (4.9%). Patients with new (first visit) Venous Leg Ulcers were more likely to receive pharmacological treatments and to be referred elsewhere, and less likely to receive dressings than patients receiving follow-up care. There appears to be a large gap between best practice guidelines and actual Venous Leg Ulcers treatments, as referrals and appropriate treatment was low. Further longitudinal studies are needed to determine the effectiveness of care for people with Venous Leg Ulcers who are managed by general practitioners.

Compression bandaging does not compromise peripheral microcirculation in patients with cellulitis of the lower leg.

Cellulitis ranks among the most frequent infections, and antibiotic treatment is the accepted mainstay of therapy. There is disagreement on the guidelines for the use of compression bandaging as supplementary treatment, and the evidence within the field is scarce. To determine whether compression bandaging impairs microcirculation in patients with cellulitis of the lower leg, thereby having a negative impact on the supply of oxygen, nutritional components, and antibiotics. Adult patients were prospectively enrolled for compression bandaging in addition to antibiotic treatment. The peripheral blood flow rate was measured before and after application of the compression bandage and on the following day. For this, we applied the heat-washout method, which has previously been shown to provide an accurate estimate of peripheral microcirculation. Comparing the blood flow rate before and after application of the compression bandage showed no significant change and therefore no alteration in microcirculation (p = 0.61). Compression bandaging of the lower leg does not impair microcirculation in patients with cellulitis. This strongly indicates that compression bandaging can play a positive role as supportive treatment in addition to standard antibiotic therapy.

[Compression Therapy in Patients with Leg Ulcers - which Costs do Really Occur?] / Kompressionstherapie bei Patienten mit Ulcus cruris ­ welche Kosten entstehen wirklich?

INTRODUCTION: Patients with leg ulcers often have severe edema of the lower extremities, which should be treated as part of a successful wound treatment. Today in Germany the necessary compression therapies are often performed with very error-prone and time-consuming short-stretch bandages only. Multicomponent systems, adaptive compression bandages and leg ulcer stocking systems are newer, much less error-prone treatment options. In addition to the often lacking knowledge, the fears of high costs are also mentioned as reasons for the lack of prescription of these systems. It was therefore our aim to investigate the costs of different treatment options, differentiated in the outpatient and inpatient sector. METHODS: For the economic calculations, both material and personnel costs were taken into account for different scenarios. RESULTS: Both material and personnel costs were included in the calculation. We were able to demonstrate that the cost for a continuous compression therapy for inpatients accrues between 5.29 Euros to 18.50 Euros per day. For the outpatient setting costs of 2.29 Euros to 34.29 Euros per day were calculated. The different constellations of compression therapy can make sense thus not only for medically but also for economically aspects. CONCLUSION: As a consequence of this data, both the different systems and the economic factors of compression therapy in patients with leg ulcers should be known to the therapists. These treatment options should then be prescribed and performed according to individual factors, taking into account the needs and abilities of the patients.

Is Buddy Taping as Effective as Plaster Immobilization for Adults With an Uncomplicated Neck of Fifth Metacarpal Fracture? A Randomized Controlled Trial.

STUDY OBJECTIVE: We compare buddy taping with plaster casting for uncomplicated fifth metacarpal (boxer's) fractures. We hypothesize buddy taping will give superior functional outcomes at 12 weeks, defined as a 10-point difference on the Shortened Disabilities of the Arm, Shoulder and Hand (quickDASH) score. METHODS: This randomized controlled trial included patients aged 18 to 70 years, with uncomplicated boxer's fractures in 2 hospitals in Queensland, Australia. The intervention consisted of buddy taping of the ring and little fingers on the affected side, in which the control group received plaster casting. Primary outcome was hand function as measured by quickDASH score (0 to 100, with 0 indicating no disability) at 12 weeks. Secondary outcomes measured at 3, 6, and 12 weeks included time off work and activities, pain, satisfaction, and the EuroQol 5-Dimension 3-Level score (measure of overall health). RESULTS: Ninety-seven patients with primary endpoint data were available for analysis, 48 in the buddy taping group and 49 in the plaster group. At 12 weeks, median quickDASH scores were the same for both groups (buddy 0, interquartile range [IQR] 0 to 2.3; plaster 0, IQR 0 to 4; difference 0; 95% confidence interval of the difference 0 to 0). Patients in the buddy taping group missed a median 0 days (IQR 0 to 7) of work compared with the plaster group's 2 days (IQR 0 to 14). Other secondary outcome measures were the same in both groups. CONCLUSION: We found that patients with boxer's fractures who were randomized to buddy taping had functional outcomes similar to those of patients randomized to plaster cast at 12 weeks. We advocate a minimal intervention such as buddy taping for uncomplicated boxer's fractures.

The scourge of burn contractures: Who will bell the cat?

INTRODUCTION: Majority of burn injuries occur in developing world. There have been many advances in burn care management. But this advance comes at a price of ever increasing burn sequel of scarring. Burn scar contractures, in spite of being preventable, continue to be a common reality in our world. This paper aims to evaluate the lacunae in burn care leading to formation of contractures, to evaluate common sites of contractures, practice of advising splintage and anti-deformity positioning. PROCEDURE: This retrospective observational study was conducted over a period of six years (January 2010-December 2015) at a tertiary Burn unit in Mumbai (India). The records of burn contracture patients were scrutinized to obtain the data regarding patient's socio-demographic profile, details of burn injury, splinting and exercises advised and details of surgeries required. Data was tabulated and analysed. RESULTS: There was a significantly lower prevalence of advice regarding splinting, mobilization exercises and pressure garments. The prevalence of early surgery was also found to be low. CONCLUSIONS: Attempt has been made to identify the factors affecting the prevalence of burn scar contractures. Authors recommend that efforts be made for improving the knowledge of the treating doctors. Also, efforts should be made to increase awareness of burn prevention and emergent management.

Does initial routine use of a compression garment reduce the risk of lower limb lymphedema after gynecological cancer treatment? A randomized pilot study in an Asian institution and review of the literature.

This is a randomized pilot study evaluating the effectiveness of customized compression garments (CG) in reducing the risk of lower limb lymphedema (LLL) in gynecological cancer patients. Patients who completed pelvic node dissection or radiation were routinely educated on reducing the risk of LLL by good skin care and manual lymphatic massage. After baseline lower limb volume perometry and clinical assessment, they were randomized to customized compression garment (CG) for 6 weeks (26 patients) or observation (30 patients). Both groups were followed up for 2 years and the primary outcome was the development of LLL. LLL incidence in the control group was 13.3% (4 of 30 patients) compared to 7.7% (2 of 26 patients) in the CG group. However the difference was not statistically significant (P=0.496). In the control group, 10.7% (3/28) who underwent node dissection developed LLL vs 7.7% (2/26) in the CG group. Among patients with node dissection plus radiation, LLL incidence was 14.3% (1/7) in the control group vs 12.5% (1/8) in the CG group. The mean onset of LLL was 12 months; compliance to CG wearing was high and QOL scores were similar in both groups. Customized low-compression CG worn for 6 weeks may have a possible benefit in reducing the risk of LLL when added to patient education on risk reduction although statistic significance was not achieved in this small pilot study. A larger multi-center study would be justified to expand these findings.

Venous leg ulcer management in clinical practice in the UK: costs and outcomes.

The aim of this study was to estimate the patterns of care and annual levels of health care resource use attributable to managing venous leg ulcers (VLUs) in clinical practice by the UK's National Health Service (NHS) and the associated costs of patient management. This was a retrospective cohort analysis of the records of 505 patients in The Health Improvement Network (THIN) Database. Patients' characteristics, wound-related health outcomes and health care resource use were quantified, and the total NHS cost of patient management was estimated at 2015/2016 prices. Overall, 53% of all VLUs healed within 12 months, and the mean time to healing was 3·0 months. 13% of patients were never prescribed any recognised compression system, and 78% of their wounds healed. Of the 87% who were prescribed a recognised compression system, 52% of wounds healed. Patients were predominantly managed in the community by nurses with minimal clinical involvement of specialist clinicians. Up to 30% of all the VLUs may have been clinically infected at the time of presentation, and only 22% of patients had an ankle brachial pressure index documented in their records. The mean NHS cost of wound care over 12 months was an estimated £7600 per VLU. However, the cost of managing an unhealed VLU was 4·5 times more than that of managing a healed VLU (£3000 per healed VLU and £13 500 per unhealed VLU). This study provides important insights into a number of aspects of VLU management in clinical practice that have been difficult to ascertain from other studies and provides the best estimate available of NHS resource use and costs with which to inform policy and budgetary decisions.

The Effect of Swaddling on Pain, Vital Signs, and Crying Duration during Heel Lance in Newborns.

To determine the effect of swaddling on pain, vital signs, and crying duration during heel lance in the newborn. This was a randomized controlled study of 74 (control: 37, experiment: 37) newborns born between December 2013 and February 2014 at the Ministry of Health Bagcilar Training and Research Hospital. An information form, observation form, and Neonatal Infant Pain Scale were used as data collection tools. Data from the pain scores, peak heart rates, oxygen saturation, total crying time, and duration of the procedure were collected using a video camera. Newborns in the control group underwent routine heel lance, whereas newborns in the experimental group underwent routine heel lance while being swaddled by the researcher. The newborns' pain scores, peak heart rates, oxygen saturation values, and crying durations were evaluated using video recordings made before, during, and 1, 2, and 3 minutes after the procedure. Pain was assessed by a nurse and the researcher. No statistically significant difference was found in the characteristics of the two groups (p > .05). The mean pain scores of swaddled newborns during and after the procedure were lower than the nonswaddled newborns (p < .05). In addition, crying duration of swaddled newborns was found to be shorter than the nonswaddled newborns (p < .05). The average preprocedure peak heart rates of swaddled newborns were higher (p < .05); however, the difference was not significant during and after the procedure (p > .05). Although there was no significant difference in oxygen saturation values before and during the procedure (p > .05), oxygen saturation values of swaddled newborns were higher afterward (p < .05). For this study sample, swaddling was an effective nonpharmacologic method to help reduce pain and crying in an effort to soothe newborns. Although pharmacologic pain management is the gold standard, swaddling can be recommended as a complementary therapy for newborns during painful procedures. Swaddling is a quick and simple nonpharmacologic method that can be used by nurses to help reduce heel stick pain in newborns.

Control of lower extremity edema in patients with diabetes: Double blind randomized controlled trial assessing the efficacy of mild compression diabetic socks.

AIMS: Persons with diabetes frequently present with lower extremity (LE) edema; however, compression therapy is generally avoided for fear of compromising arterial circulation in a population with a high prevalence of peripheral arterial disease. This double blind randomized controlled trial (RCT) assessed whether diabetic socks with mild compression could reduce LE edema in patients with diabetes without negatively impacting vascularity. METHODS: Eighty subjects with LE edema and diabetes were randomized to receive either mild-compression knee high diabetic socks (18-25mmHg) or non-compression knee high diabetic socks. Subjects were instructed to wear the socks during all waking hours. Follow-up visits occurred weekly for four consecutive weeks. Edema was quantified through midfoot, ankle, and calf circumferences and cutaneous fluid measurements. Vascular status was tracked via ankle brachial index (ABI), toe brachial index (TBI), and skin perfusion pressure (SPP). RESULTS: Seventy-seven subjects (39 controls and 38 mild-compression subjects) successfully completed the study. No statistical differences between the two groups in terms of age, body mass index, gender, and ethnicity. Repeated measures analysis of variance and Sidak corrections for multiple comparisons were used for data analyses. Subjects randomized to mild-compression diabetic socks demonstrated significant decreases in calf and ankle circumferences at the end of treatment as compared to baseline. LE circulation did not diminish throughout the study with no significant decreases in ABI, TBI or SPP for either group. CONCLUSIONS: Results of this RCT suggest that mild compression diabetic socks may be effectively and safely used in patients with diabetes and LE edema.

A high-resolution tape sensor improves the accuracy of applied pressure profiles during lower-leg bandaging - results from a study using a fibre-optic sensing tape.

Compression bandaging is a mainstay practice in the treatment of conditions such as chronic wounds and lymphoedema. However, the ability of practitioners to measure bandage application to a desired pressure profile is difficult because of sensor limitations. We have used a novel fibre-optic-based, high-resolution sub-bandage pressure monitor to measure adherence to a target pressure gradient during compression bandaging. Participants of various experience (n = 46) were asked to bandage a lower-leg manikin to a gradient of 40 (ankle) to 20 mmHg (proximal calf) in both a blinded trial and subsequently with sensor feedback. Mean pressures across all sensors for both the blind and sensor-guided trials approximated a target mean of 30 mmHg. However, the mean gradient achieved in the blinded trial showed an inverse pressure gradient to the target with a high-pressure region at the mid-calf (44 ± 19 mmHg). Correlation to the target gradient improved from R2 = 0·62 during the blind trial to 0·93 using sensor feedback, with a gradient that closely approximated the target. This demonstrates the use of high-resolution sub-bandage pressure sensing in improving the ability of practitioners to achieve a target pressure gradient in compression bandaging for clinical use and training.

Mechanical Prophylaxis after Lower Extremity Total Joint Arthroplasty: A Review.

Venous thromboembolism (VTE) is a serious complication that can occur after total hip and knee arthroplasty, and can potentially lead to significant morbidity and even mortality. While various modalities have been used to prevent VTE development, the medications can be associated with a number of adverse events. Therefore, mechanical prophylaxis with pumps and compressive devices has been used more frequently alone, or in combination, with medications. Therefore, the purpose of this study was to review the current literature on mechanical prophylaxis for VTEs after lower extremity total joint arthroplasty. Specifically, we reviewed mechanical prophylaxis after: 1) total hip arthroplasty and 2) total knee arthroplasty.

Compression therapy - current practice of care: level of knowledge in patients with venous leg ulcers.

BACKGROUND AND OBJECTIVES: Compression therapy is a mainstay in the causal treatment of patients with venous leg ulcers. It facilitates healing, reduces pain and recurrences, and increases quality of life. Up until now, there is a scarcity of scientific data with respect to the level of care and the specific knowledge of patients with venous leg ulcers. PATIENTS AND METHODS: At first presentation, patients with venous leg ulcers anonymously answered a standardized questionnaire. Participating facilities nationwide included 55 outpatient care services, 32 medical practices, four wound centers, and one specialized care center. RESULTS: Overall, 177 patients (mean age of 69.4; 75.1 % women) participated in the study. The average duration of florid venous leg ulcers was 17 months. With regard to compression therapy, 31.1 % of patients received none; 40.1 % used bandages; 28.8 % used stockings. Of the latter, 13.7 % were treated with compression class III; 67.4 %, with compression class II; and 19.6 %; with compression class I. While 70.6 % put on their stockings after getting out of bed in the morning, 21.1 % wore them day and night. In 39.2 % of individuals, the stockings caused them discomfort. Merely 11.7 % owned a donning device. On average, bandages were worn for 40.7 weeks, and 69 % were used without underpadding. In 2.8 % of patients, ankle and calf circumference was measured to monitor therapeutic success. 45.9 % reported doing leg exercises. CONCLUSIONS: Although it is considered a basic therapeutic measure in venous leg ulcers, one-third of all patients received no compression treatment. Moreover, given the long duration of ulcers, adequate product selection and correct use have to be questioned, too. Our findings indicate that improvements in the level of knowledge among users and prescribers as well as patient training are required.
