Teleconsulting in wound care: Connecting the primary care to the wound specialist reduces unnecessary referrals

In the Netherlands the primary care (General Practitioner or homecare nurse) encounter a variety of wounds ranging from traumatic to diabetic foot ulcers. According to a recent study 82.4% of the patients with a wound can be treated in a primary setting with the GP as medical supervisor. The remaining 17.6% of patients need more extensive care including advice by a specialised doctor, diagnosis and treatment. Prompt analyses and treatment of underlying causes by specialised doctors in a multidisciplinary setting is necessary for treating patients with complicated wound. This article describes the impact of Electronic Health Consultation on all wounds treated in the primary care. And describes the effect on the duration until referral to the hospital and the influence on the amount of unnecessary referrals to the hospital. All data was collected prospectively from June 2020 until October 2021. The study involved a process where primary care could seek advice from a Wound Physician at the Alrijne Wound Centre through a specialised Electronic Health Consultation. A total of 118 patients were analysed. 41/118 (34.7%) patients required a physical consultation with analysis and treatment in the hospital, after teleconsultation. The remaining 77/118 (65.3%) could be treated in primary care after Electronic Health Consultation. The mean duration of wound existence until Electronic Health Consultation was 39.3 days (range 5-271, SD: 38.5). 3/41 (7.3%) of the referrals were unnecessary. Electronic Health Consultation serves as a valuable and efficient tool for enhancing wound care, ultimately contributing to improved patient management and resource allocation within the healthcare system. This article describes the impact of Electronic Health Consultation on all wounds treated in the primary care and the influence on the duration until referral to the hospital and the influence on the amount of unnecessary referrals to the hospital.

Telemedicine-Guided Two-Incision Lower Leg Fasciotomy Performed by Combat Medics During Tactical Combat Casualty Care: A Feasibility Study

INTRODUCTION

During tactical combat casualty care, life- and limb-saving procedures might also be performed by combat medics. This study assesses whether it is feasible to use a head-mounted display (HMD) to provide telemedicine (TM) support from a consulted senior surgeon for combat medics when performing a two-incision lower leg fasciotomy.

MATERIALS AND METHODS

Nine combat medics were randomized into groups to perform a two-incision lower leg fasciotomy. One group used the Vuzix M400 and the second group used the RealWear HMT-1Z1. A third, control, group received no guidance. In the Vuzix M400 group and RealWear HMT-1Z1 group, a senior surgeon examined the results after the two-incision lower leg fasciotomy was finished to assess the release of compartments, possible collateral damage, and performance of the combat medics. In the control group, these results were examined by a surgical resident with expertise in two-incision lower leg fasciotomies. The resident's operative performance questionnaire was used to score the performance of the combat medics. The telehealth usability questionnaire was used to evaluate the usability of the HMDs as perceived by the combat medics.

RESULTS

Combat medics using an HMD were considered competent in performing a two-incision lower leg fasciotomy (Vuzix: median 3 [range 0], RealWear: median 3 [range 1]). These combat medics had a significantly better score in their ability to adapt to anatomical variances compared to the control group (Vuzix: median 3 [range 0], RealWear: median 3 [range 0], control: median 1 [range 0]; P = .018). Combat medics using an HMD were faster than combat medics in the control group (Vuzix: mean 14:14 [SD 3:41], RealWear: mean 15:42 [SD 1:58], control: mean 17:45 [SD 2:02]; P = .340). The overall satisfaction with both HMDs was 5 out of 7 (Vuzix: median 5 [range 0], RealWear: median 5 [range 1]; P = .317).

CONCLUSIONS

This study shows that it is feasible to use an HMD to provide TM support performance from a consulted senior surgeon for combat medics when performing a two-incision lower leg fasciotomy. The results of this study suggest that TM support might be useful for combat medics during tactical combat casualty care when performing life- and limb-saving procedures.

The haemostatic effect of deep-frozen platelets versus room temperature-stored platelets in the treatment of surgical bleeding: MAFOD—study protocol for a randomized controlled non-inferiority trial

Background

The Netherlands Armed Forces have been successfully using deep-frozen (− 80 °C) thrombocyte concentrate (DTC) for the treatment of (massive) bleeding trauma patients in austere environments since 2001. However, high-quality evidence for the effectiveness and safety of DTCs is currently lacking. Therefore, the MAssive transfusion of Frozen bloOD (MAFOD) trial is designed to compare the haemostatic effect of DTCs versus room temperature-stored platelets (RSP) in the treatment of surgical bleeding.

Methods

The MAFOD trial is a single-blinded, randomized controlled non-inferiority trial and will be conducted in three level 1 trauma centres in The Netherlands. Patients 12 years or older, alive at hospital presentation, requiring a massive transfusion including platelets and with signed (deferred) consent will be included. The primary outcome is the percentage of patients that have achieved haemostasis within 6 h and show signs of life. Haemostasis is defined as the time in minutes from arrival to the time of the last blood component transfusion (plasma/platelets or red blood cells), followed by a 2-h transfusion-free period. This is the first randomized controlled study investigating DTCs in trauma and vascular surgical bleeding.

Discussion

The hypothesis is that the percentage of patients that will achieve haemostasis in the DTC group is at least equal to the RSP group (85%). With a power of 80%, a significance level of 5% and a non-inferiority limit of 15%, a total of 71 patients in each arm are required, thus resulting in a total of 158 patients, including a 10% refusal rate. The data collected during the study could help improve the use of platelets during resuscitation management. If proven non-inferior in civilian settings, frozen platelets may be used in the future to optimize logistics and improve platelet availability in rural or remote areas for the treatment of (massive) bleeding trauma patients in civilian settings.

Clinical Consensus on Diagnosis and Treatment of Patients with Chronic Exertional Compartment Syndrome of the Leg: A Delphi Analysis

AIM

Defining universally accepted guidelines for the diagnosis and treatment of chronic exertional compartment syndrome (CECS) is hampered by the absence of high-quality scientific research. The aim of this Delphi study was to establish consensus on practical issues guiding diagnosis and treatment of CECS of the leg in civilian and military patient populations.

METHODS

An international expert group was queried using the Delphi technique with a traditional three-round electronic consultation. Results of previous rounds were anonymously disclosed in the questionnaire of rounds 2 and 3, if relevant. Consensus was defined as > 70% positive or negative agreement for a question or statement.

RESULTS

The panel consisted of 27 civilian and military healthcare providers. Consensus was reached on five essential key characteristics of lower leg CECS. The panel achieved partial agreement regarding standardization of the diagnostic protocol, including muscle tissue pressure measurements. Consensus was reached on conservative and surgical treatment regimens. However, the experts did not attain consensus on their approach of postoperative rehabilitation and preferred treatment approach of recurrent or residual disease. A summary of best clinical practice for the diagnosis and management of CECS was formulated by experts working in civilian and military healthcare facilities.

CONCLUSION

The Delphi panel reached consensus on key criteria for signs and symptoms of CECS and several aspects for conservative and surgical treatment. The panel did not agree on the role of ICP values in the diagnostic process, postoperative rehabilitation guidelines protocol, or the preferred treatment approach for recurrent or residual disease. These aspects serve as a first attempt to initiate simple guidelines for clinical practice.

Consensus on resuscitative endovascular balloon occlusion of the Aorta: A first consensus paper using a Delphi method

BACKGROUND

To further strengthen the evidence base on the use of Resuscitative Endovascular Balloon occlusion of the Aorta (REBOA) we performed a Delphi consensus. The aim of this paper is to establish consensus on the indications and contraindications for the use of REBOA in trauma and non-trauma patients based on the existing evidence and expertise.

STUDY DESIGN

A literature review facilitated the design of a three-round Delphi questionnaire. Delphi panelists were identified by the investigators. Consensus was reached when at least 70% of the panelists responded to the survey and more than 70% of respondents reached agreement or disagreement.

RESULTS

Panel members reached consensus on potential indications, contra-indications and settings for use of REBOA (excluding the pre hospital environment), physiological parameters for patient selection and indications for early femoral access. Panel members failed to reach consensus on the use of REBOA in patients in extremis (no pulse, no blood pressure) and the use of REBOA in patients with two major bleeding sites.

CONCLUSIONS

Consensus was reached on indications, contra indications, physiological parameters for patient selection for REBOA and early femoral access. The panel did not reach consensus on the use of REBOA in patients in pre-hospital settings, patients in extremis (no pulse, no blood pressure) and in patients with 2 or more major bleeding sites. Further research should focus on the indications of REBOA in pre hospital settings, patients in near cardiac arrest and REBOA inflation times.

Migration of Aortic Occlusion Balloons in an in vitro model of the human circulation

BACKGROUND

Aortic Occlusion Balloons (AOB) are used for hemorrhage control in hemodynamically unstable patients. Stability of an AOB is essential for reliable aortic occlusion. The primary aim of this study is to determine whether different types of AOB migrate after total, intermittent or partial occlusion in a porcine aorta positioned in an in vitro model.

MATERIALS AND METHODS

A porcine thoracic aortic section was positioned in a model of the human circulation. Primary and secondary migration was tested in Cook Coda™ 2-9.0-35-120-32 and 2-10-35-140-46, Cook Medical, USA; Rescue balloon™ Tokai RB-167080-E, Tokai Medical Products, Japan; Reliant™ AB46, Medtronic, USA; Russian prototype AOB; ER-REBOA™, Prytime Medical Devices, USA; LeMaitre™ 28 and 45 Aortic Occlusion Catheter, LeMaitre Vascular, USA. These AOB were tested in hypotensive, normotensive and hypertensive scenarios. Migration in total occlusion, intermittent occlusion and partial occlusion was recorded for all AOB.

RESULTS

Limited primary migration occurred in all AOB after total occlusion. The Cook Coda™ 2-9.0-35-120-32 balloon showed maximal migration in 1 test cycle. No migration occurred during intermittent occlusion. Kinking occurs in various degrees but does not seem to prevent a successful occlusion of the aorta. No migration occurred during partial occlusion except in the Russian prototype AOB. In a partial occlusion scenario, distal perfusion occurred only with 5 ml remaining in all balloon types.

CONCLUSIONS

All AOB were successful in full aortic occlusion. Limited primary migration occurred in all AOB after total occlusion only the Cook Coda™ 2-9.0-35-120-32 balloon showed maximal migration once. No migration occurred during intermittent occlusion, during partial occlusion only the Russian prototype AOB migrated. Stiffness and size of the catheter are important factors in preventing migration and kinking.

A systematic review and meta-analysis of the use of resuscitative endovascular balloon occlusion of the aorta in the management of major exsanguination

BACKGROUND

Circulatory collapse is a leading cause of mortality among traumatic major exsanguination and in ruptured aortic aneurysm patients. Approximately 40% of patients die before hemorrhage control is achieved. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an adjunct designed to sustain the circulation until definitive surgical or endovascular repair. A systematic review was conducted for the current clinical use of REBOA in patients with hemodynamic instability and to discuss its potential role in improving prehospital and in-hospital outcome.

METHODS

Systematic review and meta-analysis (1900-2017) using MEDLINE, Cochrane, EMBASE, Web of Science and Central and Emcare using the keywords "aortic balloon occlusion", "aortic balloon tamponade", "REBOA", and "Resuscitative Endovascular Balloon Occlusion" in combination with hemorrhage control, hemorrhage, resuscitation, shock, ruptured abdominal or thoracic aorta, endovascular repair, and open repair. Original published studies on human subjects were considered.

RESULTS

A total of 490 studies were identified; 89 met criteria for inclusion. Of the 1436 patients, overall reported mortality was 49.2% (613/1246) with significant differences (p < 0.001) between clinical indications. Hemodynamic shock was evident in 79.3%, values between clinical indications showed significant difference (p < 0.001). REBOA was favored as treatment in trauma patients in terms of mortality. Pooled analysis demonstrated an increase in mean systolic pressure by almost 50 mmHg following REBOA use.

CONCLUSION

REBOA has been used in trauma patients and ruptured aortic aneurysm patients with improvement of hemodynamic parameters and outcomes for several decades. Formal, prospective study is warranted to clarify the role of this adjunct in all hemodynamic unstable patients.

A Peculiar Case of a Floating Angio-Seal

Purpose

To show a complication of the use of an Angio-Seal™ closure device.

Case

We present a patient with a systolic murmur in his femoral artery after PCI. The murmur was caused by a dislocated Angio-Seal™, a vascular closure device. This was diagnosed by Doppler Ultrasound. The device was surgically removed.

Conclusion

Vascular complications, such as lower limb ischemia, requiring surgical intervention tend to be higher after use of a vascular closure device. We advise routine physical examination of the puncture site after percutaneous closure with a vascular closure device, such as an Angio-Seal™. The removal of the device can be performed via an open or endoscopic approach, based on available experience.

Necrotising fasciitis due to an infected sebaceous cyst

The current case presents a patient who was admitted to our hospital with the diagnosis of cellulitis of the right groin. In the following days, the patient's condition deteriorated and developed a septic shock. Exploration in the operating room showed a necrotising fasciitis of the adductor muscles, with an infected sebaceous cyst in the inguinal crest as port d'entrée. After extensive surgical debridement, antibiotic therapy, haemodynamic and respiratory support, the patient recovered. Necrotising fasciitis is a rare but very lethal condition, which necessitates aggressive surgical therapy and antibiotic support. The current case report is the first report to show a necrotising fasciitis due to an infected sebaceous cyst.

Infections of intravascular bare metal stents: a case report and review of literature

OBJECTIVE

The objective of the paper is to present a case of an infected bare metal stent in the left common iliac artery that was removed by an urgent operation, and to review the literature on diagnosis and outcome of infected coronary and non-coronary metal stents.

METHODS

A systematic search of the Medline database was performed with the purpose of identifying risk factors, signs and symptoms, imaging strategies, and treatment modalities of bare metal stent infections, both coronary and peripheral.

RESULTS

In total, 76 additional studies/case reports (48 non-coronary; 29 coronary) were included and analyzed. Intravascular bare metal stent infections are a rare but serious complication, often leading to emergency surgery (overall: 75.3%; non-coronary cases: 83.3%; coronary cases: 62.1%). In 25.0% of the non-coronary cases, infection led to amputation of an extremity or removal of viscera. Reported mortality was up to 32.5% of the cases (non-coronary: 22.9%; coronary 48.3%). Physicians should always be suspicious of a stent infection when patients present with aspecific symptoms such as fever and chills after stent placement. Additional imaging can be used to detect the presence of a pseudoaneurysm. A PET-CT is an ideal medium for identification of a stent infection.

CONCLUSIONS

Intravascular stent infection is associated with a high risk of morbidity and mortality. Surgery is the preferred treatment option, but not always possible, especially in patients with a coronary stent. In selected cases, bare metal stent infections may be prevented by the use of prophylactic antibiotics at stent placement.

Pain perception during and after VNUS ClosureFAST™ procedure

The objective of the study was first to quantify the level of pain that patients experience during VNUS ClosureFASTTM and in the first week following treatment. Secondly, to investigate the use of pain medication. Thirdly, to identify after how many days patients return to daily activities and whether pain is a factor of influence. A prospective descriptive cohort study was carried out. In all, 104 consecutive VNUS ClosureFAST procedures for greater saphenous vein (GSV) incompetence between 18 May and 28 August 2009 in the HagaZiekenhuis were included. A visual analogue score (VAS) was recorded immediately after the procedure. These patients were asked to register pain scores during the week following the procedure, the amount of pain medication if used and the time elapsed between the procedures and resuming daily activities. The average VAS score during the VNUS Closure procedure was four. The first three days after the procedure the VAS score was 2. After four days, the average score was 1. The average return to daily activities was on day two after the procedure. In total, 24% of all patients used paracetamol after the procedure. In summary, VNUS ClosureFAST procedure for GSV incompetence is not a painless treatment. After an average of two days, patients return to their daily activities. Pain does not seem to be a major factor in the resumption. Seventy-six percent of patients do not use any pain medication.
