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.

Direct Hospital Costs per Case of Periprosthetic Hip and Knee Joint Infections in Europe - A Systematic Review.

BACKGROUND: The rise of periprosthetic joint infections (PJIs) due to aging populations is steadily increasing the number of arthroplasties and treatment costs. This study analyzed the direct health care costs of PJI for total hip arthroplasty and total knee arthroplasty (TKA) in Europe. METHODS: The databases PubMed, Scopus, Embase, Cochrane, and Google Scholar were systematically screened for direct costs of PJI in Europe. Publications that defined the joint site and the procedure performed were further analyzed. Mean direct health care costs were calculated for debridement, antibiotics, and implant retention (DAIR), one-stage, and 2-stage revisions for hip and knee PJI, respectively. Costs were adjusted for inflation rates and reported in US-Dollar (USD). RESULTS: Of 1,374 eligible publications, 12 manuscripts were included in the final analysis after an abstract and full-text review. Mean direct costs of $32,933 were identified for all types of revision procedures for knee PJI. The mean direct treatment cost including DAIR for TKA after PJI was $19,476. For 2-stage revisions of TKA, the mean total cost was $37,980. For all types of hip PJI procedures, mean direct hospital costs were $28,904. For hip DAIR, one-stage and 2-stage treatment average costs of $7,120, $44,594, and $42,166 were identified, respectively. CONCLUSIONS: Periprosthetic joint infections are associated with substantial direct health care costs. As detailed reports on the cost of PJI are scarce and of limited quality, more detailed financial data on the cost of PJI treatment are urgently required.

Comparison of wound surface area measurements obtained using clinically validated artificial intelligence-based technology versus manual methods and the effect of measurement method on debridement code reimbursement cost.

BACKGROUND: Evidence shows that ongoing accurate wound assessments using valid and reliable measurement methods is essential to effective wound monitoring and better wound care management. Relying on subjective interpretation in measuring wound dimensions and assuming a rectilinear shape of all wounds renders an inconsistent and inaccurate wound area measurement. OBJECTIVE: The authors investigated the discrepancy in wound area measurements using a DWMS versus TPR methods and compared debridement codes submitted for reimbursement by assessment method. METHODS: The width and length of 177 wounds in 56 patients were measured at an outpatient clinic in the United States using the TPR method (width × length formula) and a DWMS (traced wound dimensions). The maximal allowable payment for debridement was calculated for both methods using the reported CPT codes based on each 20-cm2 estimated surface area. RESULTS: The average wound surface area was significantly higher with the TPR method than with the DWMS (20.20 and 12.81, respectively; P = .025). For patients with dark skin tones, ill-defined wound edges, irregular wound shapes, unhealthy tissues, and the presence of necrotic tissues, the use of the DWMS resulted in significantly lower mean differences in wound area measurements of 14.4 cm2 (P < .008), 8.2 cm2 (P = .040), 6.8 cm2 (P = .045), 13.1 cm2 (P = .036), and 7.6 cm2 (P = .043), respectively, compared with the TPR method. Use of the DWMS for wound surface area measurement resulted in a 10.6% lower reimbursement amount for debridement, with 82 fewer submitted codes, compared with the TPR method. CONCLUSIONS: Compared with the DWMS, TPR measurements overestimated wound area more than 36.6%. This overestimation was associated with dark skin tones and wounds with irregular edges, irregular shapes, and necrotic tissue.

Negative pressure wound therapy with instillation in lower extremity wounds may contribute to cost-savings: 4 case reports.

BACKGROUND: Use of negative pressure wound therapy with instillation and dwell time (NPWTi-d) can assist with wound bed preparation for successful closure. The authors present their experience using NPWTi-d to manage lower extremity wounds in 4 patients and discuss the feasibility of improving cost efficiency. METHODS: NPWTi-d involved instillation of normal saline with an 8-to 10 minute dwell time, followed by 3 to 3.5 hours of -125 mm Hg. Therapy continued for 6 to 7 days with dressing changes every 2 to 3 days. RESULTS: Patients were all male, between the ages of 24 and 83 years old. Wound etiologies included chemical burn, deep tissue laceration, compartment syndrome with hematoma, and diabetic foot osteomyelitis. All wounds required cleansing. Prior to NPWTi-d, surgical debridement and antibiotics were administered as necessary. After NPWTi-d, the wounds exhibited healthy granulation and reduced in size, allowing for discharge to outpatient care. Upon follow-up 2 to 6 months later, no patients experienced wound complications or required readmission to the operating room, potentially saving on time and cost. CONCLUSION: In these patients, use of NPWTi-d assisted in cleansing the wound surface and producing a positive healing outcome. Despite higher initial costs of NPWTi-d over standard dressings, a wound management protocol including NPWTi-d may help mitigate expenses incurred by delayed healing.

Defensins of Lucilia sericata Larvae and Their Influence on Wound Repair Processes in Practical Assessment-A Study of Three Cases.

Bacteria inhabiting chronic wounds form a biofilm that prolongs and slows down the healing process. Increasingly common antibiotic resistance requires clinicians to search for effective and alternative treatment methods. Defensins are the most common antimicrobial peptides capable of eradicating pathogens. Their discovery in maggot secretions allowed for a broader understanding of the healing mechanisms, and approving the use of Lucilia sericata fly larvae in the treatment of infected wounds resulted in an effective and safe procedure. The aim of the study was to present the possibility of biofilm elimination in a chronic wound by means of medical maggots (Lucilia sericata) with the example of three selected clinical cases. The observation included three women who met the inclusion criterion of having venous insufficiency ulcers with inhibited regeneration processes. Medical maggots were applied in a biobag for three days, and observation was conducted for 21 consecutive days. In 2 cases, a significant elimination of necrotic tissue from the wound bed with local granulation tissue was observed 72 h after application of a larvae colony on the wounds. In 1 case, the application of the larvae accelerated the repair process by reducing the wound area by approximately 40% at the time of observation. The formation of biofilm in a chronic wound is one of the main causes of disturbances in its effective healing. Combining procedures (scraping, antiseptic compresses, MDT, NPWT) related to wound debridement increases the effectiveness of biofilm elimination. The use of medical maggots is a safe and effective method of choice, and it enhances the processes of debridement. However, confirmed indisputable data on their effectiveness and frequency of use in the process of stimulating healing processes are still not available in the literature.

Pediatric Burns Debridement Under Sedoanalgesia During the COVID-19 Pandemic: A Cost-Effective Alternative.

Early debridement of childhood burns under sedoanalgesia in the emergency department (ED) may help to reduce the need of surgery and delay in treatment. We performed a retrospective study in burned children who underwent debridement in the ED under sedoanalgesia between March 2020 and December 2020 (COVID group), and were compared with the same months in 2019 (control group). Demographics, burns features, admission rate, and estimated costs associated were collected. A total of 733 children presented at the ED with burns (302 COVID group and 431 control group) without significant differences in burn features between them. Admission rate was significantly lower in COVID group (9.4% vs 19.4%; P < .001), as was the total associated cost for each group ($101 585 vs $209 656; P < .001). The use of sedoanalgesia for the early treatment of pediatric burns in the ED during COVID-19 pandemic is a cost-effective alternative that has reduced the need for hospital admission and associated costs.

Reduced Costs, Complications, and Length of Stay After Arthroscopic Versus Open Irrigation and Débridement for Knee Septic Arthritis.

BACKGROUND: In the treatment of native knee bacterial septic arthritis, the optimal irrigation and débridement modality-arthroscopic versus open-is a matter of controversy. We aim to compare revision-free survival, complications, and resource utilization between these approaches. METHODS: The National Readmission Database was queried from 2016 to 2019 to identify patients using International Classification of Diseases, 10th revision, diagnostic and procedure codes. Days to revision irrigation and débridement (I&D), if any, were calculated for patients during index admission or subsequent readmissions. Multivariate regression was used for healthcare utilization analysis. Survival analysis was done using Kaplan-Meier analysis and Cox proportional hazard regression. RESULTS: A total of 14,365 patients with native knee septic arthritis undergoing I&D were identified, 8,063 arthroscopic (56.1%) and 6,302 open (43.9%). The mean follow-up was 148 days (interquartile range 53 to 259). A total of 2,156 patients (15.0%) underwent revision I&D. On multivariate analysis, arthroscopic I&D was associated with a reduction in hospital costs of $5,674 and length of stay of 1.46 days (P < 0.001 for both). Arthroscopic I&D was associated with lower overall complications (odds ratio [OR] 0.63, P < 0.001), need for blood transfusion (OR 0.58, P < 0.001), and wound complications (OR 0.32, P < 0.001). Revision-free survival after index I&D was 95.3% at 3 days, 91.0% at 10 days, 88.3% at 30 days, 86.0% at 90 days, and 84.5% at 180 days. No statistically significant difference was observed between surgical approaches on Cox modeling. DISCUSSION: Risk of revision I&D did not differ between arthroscopic and open I&D; however, arthroscopy was associated with decreased costs, length of stay, and complications. Additional study is necessary to confirm these findings and characterize which patients require an open I&D. LEVEL OF EVIDENCE: III.

Synchronous circular frame stabilisation and microsurgical soft tissue reconstruction for open lower limb fractures-A cost analysis and description of the surgical technique.

INTRODUCTION: Current surgical paradigms for ortho-plastic management of IIIB open tibial fractures make compromises. Often, definitive circular frame stabilisation is delayed until the soft tissue envelope is secure to allow access for further soft tissue reconstruction if required. This delay has potential clinical and cost implications. A previous study showed acute circular frame stabilisation performed concurrently or before soft tissue reconstruction was feasible without additional soft tissue reconstruction problems. This study examines potential resource savings using this approach. METHODS: All open tibial fractures managed by circular fixator and microsurgical soft tissue reconstruction between April 2015 and June 2019 were identified from a prospectively maintained database. Those receiving circular frame stabilisation with synchronous microsurgical soft tissue reconstruction were considered cases; those in whom the frame stabilisation was delayed were controls. Cost data were derived from the Patient Level Information and Costing System. Salvage cases and those with incomplete treatment were excluded. RESULTS: Nine cases and 25 controls were evaluated. No statistically significant difference was observed between groups in terms of age, sex, injury severity score, time to debridement, time to coverage, length of follow up, or time to union. Median length of stay was 13.3 and 19.7 days for cases and controls respectively (p<0.01). Cases required fewer procedures (2.3) compared to controls (4.5) (p<0.001). The cost of care was less for cases (£25,527) than controls (£32,952) (p <0.05). No cases returned to theatre with flap failure or flap compromise. Complications were similar between groups. CONCLUSION: In suitable patients, synchronous circular frame stabilisation and microsurgical soft tissue reconstruction is a safe, clinically effective, and cost-saving option.

Assessment of salivary alpha amylase and mucin-4 before and after non-surgical treatment of peri-implant mucositis.

BACKGROUND: The present study was based on the null hypothesis that there is no difference in clinicoradiographic parameters and whole salivary alpha amylase (AA) and mucin-4 levels before and after non-surgical mechanical debridement (NSMD) of patients with peri-implant mucositis (PM). The aim was to assess whole salivary AA and mucin-4 levels before and after treatment of PM. METHODS: Patients with PM (Group-1) and individuals without peri-implant diseases (Group-2) were included. Demographic data was collected and peri-implant modified plaque and bleeding indices (mPI and mBI, respectively), probing depth (PD) and crestal bone loss were measured at baseline. Levels of AA and mucin-4 were assessed in unstimulated whole saliva samples. All patients underwent full-mouth non-surgical periodontal therapy (NSPT) and NSMD; and clinical parameters and salivary biomarkers were re-assessed after 3 months. Level of significance was set at P < 0.01. RESULTS: Twenty-six and 32 individuals were included in groups 1 and 2, respectively. None of the participants had periodontitis. At baseline clinical periodontal parameters (PI [P < 0.001], GI [P < 0.001], clinical AL [P < 0.001] and PD [P < 0.001]) were significantly high in Group-1 than Group-2. At 3-month follow-up, there was a statistically significant reduction in clinical periodontal and peri-implant parameters (PI [P < 0.01], GI [P < 0.01], and PD [P < 0.01]) in Group-1 compared with their baseline values. At baseline, salivary AA levels were significantly high in Group-1 than Group-2 (P < 0.01). At 3-month follow-up, there was no significant difference in whole salivary AA levels among patients in groups 1 and 2. CONCLUSIONS: The AA and mucin-4 levels are potential biomarkers for evaluation of peri-implant diseases including PM. Mechanical instrumentation continues to be the most predictable treatment option for the management of peri-implant diseases.

Severe Pancreatitis Multidisciplinary Working Group: Exploratory Analysis to Optimize Care and Cost.

INTRODUCTION: The minimally invasive step-up approach to pancreatitis improves outcomes. Multidisciplinary working groups may best facilitate this approach. However, support for these working groups requires funding. We hypothesize that patients requiring surgical debridement generate sufficient revenue to sustain these working groups. Furthermore, patients selected for surgical debridement by the working group will have a higher rate of percutaneous and endoscopic intervention in adherence to the step-up approach. METHODS: We conducted an observational cohort study of all patients with severe acute and/or necrotizing pancreatitis whose care was overseen by our multidisciplinary working group (October 2015 through January 2019). Patient demographics, hospital treatments, and outcomes data were compared between those who underwent surgical debridement and those who did not. Hospital billing data were also collected from those who are undergoing surgical debridement and compared to institutional benchmarks for financial sustainability. RESULTS: A total of 108 patients received care overseen by the working group, 10 of which progressed to surgical debridement. The mean contribution margin percentages for each patient in the surgical debridement group were higher than the threshold value for financial sustainability, 39% (60.34% ± 16.66%; P = 0.004). Patients in the surgical debridement group were more likely to undergo intervention by interventional radiologist (odds ratio, 1.58; P = 0.005). The mortality was higher in the nonsurgical debridement group (odds ratio, 15; P = 0.008). CONCLUSIONS: Our multidisciplinary working group delivered step-up care to patients with pancreatitis. Patients requiring surgical debridement generated a significantly positive contribution margin that could be used to help support the costs associated with providing multidisciplinary care.

Cost and clinical effectiveness of aggressive surgical debridement and delayed primary closure of infected cardiac surgical wounds.

OBJECTIVE: Postoperative wound infection in cardiac surgery remains a subject of significant concern due to associated morbidity, prolonged hospital stay and rise in treatment cost. A conservative management approach to postoperative wound infection with topical dressings and healing by secondary intention is not cost-effective and cosmetic results are less acceptable. We developed our institutional protocol for the treatment of infected postoperative cardiac surgical wounds to reduce hospital stay and improve cosmetic outcome. This study aims to compare our institutional protocol with the conservative management approach. METHODS: Adult patients with postoperative superficial or deep sternal and/or leg wound infection were divided into two equal-sized groups and data collected from medical records. Group A was treated according to our institutional protocol of aggressive surgical debridement and delayed primary closure. Group B was treated according to conservative management with topical antiseptic wound dressings and healing by secondary intention. Data were analysed in retrospect with comparative statistics. RESULTS: A total of 30 patients took part in the study. Group A (n=15, seven male, eight female) had a mean age of 55.34±12.84 years. Group B (n=15, eight male, seven female) had a mean age of 56.46±10.21 years. Mean length of hospital stay in Group A and Group B was 5.13±2.06 and 36.67±22.28 days, respectively (p<0.0001). Calculated mean hospital costs were 16,271.61±6815.50 Saudi Riyals (approximately equivalent to $4330±700 USD) in Group A and 116,212.2±26,311 Saudi Riyals (approximately equivalent to $30,932±1813 USD) in Group B (p<0.05). Patients in Group A had linear scars comparable with primary postoperative wound scars, whereas patients in Group B had excessive non-linear scarring. CONCLUSION: In this study, cost and clinical effectiveness of aggressive surgical debridement and delayed primary closure was superior to conservative management with topical antiseptic wound dressings and healing by secondary intention in terms of a shorter hospital stay and better cosmetic outcome.

Trends in Medicare utilization and reimbursement for wound debridement procedures 2012-2017.

Wound care accounts for more than $6 billion of health expenditure in the United States annually. In addition, Medicare reimbursement per relative value unit has remained flat with respect to inflation over the past 20 years. Yet, physicians face increasing operating costs. The economic effects of declining inflation-adjusted Medicare physician reimbursement on the use of wound debridement procedures have yet to be elucidated. This study describes trends in Medicare reimbursement, utilization, and total Medicare expenditure for wound debridement procedures. Using Medicare claims data, we aggregated the volume of services and average Medicare reimbursement for wound debridement procedures over the calendar years 2012 to 2017. For each billing code, we estimated inflation-adjusted total Medicare expenditure by multiplying the average inflation-adjusted Medicare reimbursement by the aggregate volume of services. The average inflation-adjusted payment for wound debridement procedures decreased by 6% from 2012 to 2017. Over this time period, the utilization of wound care procedures increased 32%. Total inflation-adjusted annual Medicare expenditure on wound care increased 24% from 2012 to 2017. Therefore, despite declining physician reimbursement rates, total Medicare expenditure on wound debridement increased from 2012 to 2017. This increase in total Medicare expenditure was driven by higher utilization of wound debridement procedures.

Economic burden of surgical management of surgical site infections following hip and knee replacements in Calgary, Alberta, Canada.

OBJECTIVE: To evaluate the cost of 1-stage and 2-stage revisions, debridement, antibiotic and implant retention (DAIR) and DAIR with liner exchange for complex surgical site infections (SSIs) following hip and knee replacements. DESIGN: Retrospective population-based economic analysis of patients undergoing intervention for SSIs between April 1, 2012 and March 31, 2019. SETTING: The study was conducted in the Calgary zone of Alberta Health Services (AHS) in Canada. PARTICIPANTS: Individuals >18 years with complex SSI following hip or knee replacement. METHODS: Patients with complex SSIs were identified using the AHS infection prevention and control database. A combination of microcosting and gross costing methods were used to estimate 12- and 24-month costs following the initial hospital admission for arthroplasty. Subgroup, inverse Gaussian and γ regression analyses were used to evaluate the impact of age and comorbidities on cost. RESULTS: In total, 142 patients with complex SSIs were identified, with a mean age of 66.8 years. Total direct medical costs in United States dollars of 2-stage revisions were ($100,992 (95% CI, 34,587-167,396) at 12 months. The 1-stage revision ($41,176; 95% CI, 23,361-58,991), DAIR with liner exchange ($41,267; 95% CI, 29,923-52,612) and DAIR ($46,605; 95% CI, 15,277-76,844) were associated with fewer costs at 12 months. Age >65 years and chronic complications of diabetes and hypertension were associated with increased costs in subgroup and regression analysis. CONCLUSIONS: Medical costs are highest at 12 months and for 2-stage revisions in hip and knee complex SSI cases. Further work should explore surgical outcomes correlated with costs to enhance patient care.

Clinical outcomes of performance of dental students using erythritol powder by means of air polishing with ultrasonic debridement with students' assessment: Part II.

OBJECTIVE: Assessment of a dental student's clinical performance is essential for providing feedback for improving education. This study evaluated the ability of undergraduate dental students to treat periodontal patients with two techniques, ultrasonic debridement with polishing (UD+P) and the erythritol powder air polishing with ultrasonic instrumentation (EPAP+UD) in a split-mouth design. METHODS: The study was conducted on undergraduate students with patients suffering from gingivitis and stage I periodontitis with grade A. The evaluation consisted of two parts: first, assessment of the student by clinical indices (full mouth plaque index (FMPI), calculus index (CI), remaining calculus index (RCI), modified gingival index (MGI) and papillary bleeding index (PBI)) at baseline, immediately and after 2 weeks. In addition to assessing treatment time for each student; and second, obtaining student feedback about the two methods used. RESULTS: Five undergraduate fourth years' students, and thirteen patients participated. Statistically significant decreases in FMPI, CI, MGI and PBI between baseline and 2 weeks post-treatment were noted in both test and control groups. At 2 weeks of inter-group comparisons, there was a statistically significant difference in FMPI and MGI indices, and immediately after the treatment, there was also a significant reduction in FMPI and CI. Treatment time was significantly less for the EPAP+UD method, and it got 10-time method preferring in comparison with the control group (UD+P) by students. CONCLUSION: The undergraduate dental student has the capacity to treat the periodontal patient using both approaches with a preference for the EPAP+UI approach over UI+P. In addition, this EPAP+UI is a promising method of education.

Redefining Slough: A New Classification System to Improve Wound Bed Assessment and Management.

Management of the wound bed to optimize healing accounts for a large portion of the considerable cost of wound management in the United States. Slough is a term that most clinicians use every day but is one that few truly understand. Most clinicians use slough to refer to any yellowish material noted on the wound surface. If the material is not red or black, it is classified as slough. In this article, new terminology and a clinically useful classification system for the various forms of slough are presented with the goal of helping clinicians better describe the wound bed appearance and choose appropriate interventions to maximize wound healing.

Maggot Debridement Therapy for Chronic Leg and Foot Ulcers: A Review of Randomized Controlled Trials.

OBJECTIVE: To critically analyze the existing randomized controlled trials (RCTs) on the clinical, economic, and psychological implications of maggot debridement therapy (MDT). DATA SOURCES: An exhaustive literature search for English-language publications was conducted using MEDLINE, EMBASE, and PubMed. STUDY SELECTION: Keywords used for the search were based on the PICO (Population, Intervention, Comparison, Outcome) framework. The titles, abstracts, and relevant full-text articles were screened. Seven RCTs were selected after applying the inclusion and exclusion criteria. DATA EXTRACTION: Data pertaining to the primary and secondary outcomes of each study were extracted. DATA SYNTHESIS: The data extracted were evaluated and categorized into clinical, economic, and psychological outcomes pertaining to MDT. A judicious evaluation of these outcomes was made, and the following conclusions were drawn. CONCLUSIONS: There exists heterogeneity in the extant RCTs, but MDT appears to be effective for a quick early debridement. For diabetic foot ulcers, MDT improves debridement, controls infection, and enhances wound healing. In chronic peripheral vascular disease ulcers, it aids in early debridement, but the final outcome is equivocal. Further robust integrated health economic and parallel qualitative assessment studies are recommended to understand the cost-effectiveness and patient acceptability and experience.

Trends in Endoscopic Sinonasal Debridement in the Medicare Population.

INTRODUCTION: Nasal/sinus endoscopy with biopsy/polypectomy/debridement, or Current Procedure Terminology code 31237, is one of the top 10 most frequent and highest billed otolaryngology procedures among Medicare patients. We analyzed temporal and geographic trends in endoscopic debridement, and correlated them with sinus surgery and balloon sinuplasty trends. METHODS: Medicare Part-B National Summary Data Files were analyzed from 2000 to 2016 for temporal trends of endoscopic debridement. Medicare Physician and Other Supplier Public Use Files detailing provider information were collected and analyzed from 2012 to 2016. Individual providers performing a reportable number of procedures were included. Linear regression was used to correlate endoscopic debridement, sinus surgery, and balloon sinuplasty procedures. RESULTS: Between 2000 and 2016, the number of endoscopic debridement procedures increased from 31,579 to 79,762 (6.0% average annual growth). The annual total payments increased from $5,944,582 to $19,438,956 (8.4% average annual growth), with average allowed charge per procedure increasing from $188.24 to $243.71. The greatest and least number of debridement procedures occurred in the Southeast (12,703) and New England (1810) regions, respectively. There was a positive correlation between providers (n = 752) performing endoscopic debridement and sinus surgery (r = 0.31, p < 0.001), which was similar to providers performing endoscopic debridement and balloon sinuplasty (r = 0.29, P < 0.001). CONCLUSION: Otolaryngologists continue to perform increasing numbers of endoscopic debridements and receive increasing payments. There is some geographic variation in these trends. Among individual providers, there was a positive correlation between the number of endoscopic debridement procedures and both the number of balloon sinuplasty and sinus surgery procedures.

Cost-Effectiveness Analysis Based on Intelligent Electronic Medical Arthroscopy for the Treatment of Varus Knee Osteoarthritis.

The incidence of inverted knee osteoarthritis is slowly increasing, there are technical limitations in the treatment, and the operation is difficult. In this article, we will study the benefits and costs of arthroscopic cleaning treatments based on intelligent electronic medicine. This article focuses on knee osteoarthritis patients in the EL database. There are 12 male patients, accounting for 66.67%, and 6 female patients, accounting for 33.33%. The average body mass index (BMI) of the patients was 28.08, the average time from first knee discomfort to surgery was 28.44 months, and the average time of arthroscopic debridement treatment for patients with VKOH knee osteoarthritis was 143.11 minutes. One case of perioperative complication occurred within 35 days after operation, which was a soleus muscle intermuscular venous thrombosis. After immobilization and enhanced anticoagulation for 1 week, it was stable without risk of shedding. The average postoperative study time was 20.00 months. The electronic medical arthroscopy cleaning treatment plan in this article can greatly improve the quality of life of patients and can check the pathological state in time, with low cost. In the course of treatment, comprehensive treatment costs can be saved by 45%. Arthroscopic clean-up treatment can not only reduce knee pain and other uncomfortable symptoms, restore normal knee joint function, and improve the quality of life of patients, but also correct the unequal length of the lower limbs, thereby avoiding spinal degeneration caused by knee instability. Therefore, it is the first choice for the treatment of advanced knee osteoarthritis in patients with VKOH.

Efficacy of Versajet hydrosurgery system in chronic wounds: A systematic review.

Studies demonstrating the effectiveness of hydrosurgery for chronic wounds are extremely limited. This systematic review aimed to evaluate the efficacy of hydrosurgery compared with conventional debridement in chronic wounds, skin ulcers, and non-acute wounds. This PROSPERO-registered review was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. A systematic search was performed in PubMed, Scopus, and Cochrane Library databases. Abstracts of all studies were screened independently by two reviewers. The bias of prospective randomised controlled studies was assessed using the Cochrane Collaboration's tool for assessing the risk of bias and RevMan 5.4 software, whereas the bias of retrospective comparative studies was evaluated using the Risk of Bias Assessment Tool for Non-randomised Studies. Two prospective randomised controlled trials, two retrospective comparative studies, and three prospective non-comparative studies were included. Hydrosurgery enabled rapid debridement. The Versajet Hydrosurgery System saved 8.87 minutes compared with the conventional methods. Similarly, the debridement quality was high with this system. The debridement number needed to achieve adequate wound beds was fewer in the hydrosurgery group than in the conventional group. These superiorities lead to subsequent success and cost-effectiveness. As there were only two prospective randomised controlled studies, and much information was missing, the risk of bias was unclear. This review confirmed that hydrosurgery is useful for the debridement of chronic wounds, considering the procedural speed and quality.
