The impact of outpatient versus inpatient management on health-related quality of life outcomes for patients with malignant pleural effusion: the OPTIMUM randomised clinical trial.

BACKGROUND: The principal aim of malignant pleural effusion (MPE) management is to improve health-related quality of life (HRQoL) and symptoms. METHODS: In this open-label randomised controlled trial, patients with symptomatic MPE were randomly assigned to either indwelling pleural catheter (IPC) insertion with the option of talc pleurodesis or chest drain and talc pleurodesis. The primary end-point was global health status, measured with the 30-item European Organisation for Research and Treatment of Cancer Quality of Life Core Questionnaire (EORTC QLQ-C30) at 30 days post-intervention. 142 participants were enrolled from July 2015 to December 2019. RESULTS: Of participants randomly assigned to the IPC (n=70) and chest drain (n=72) groups, primary outcome data were available in 58 and 56 patients, respectively. Global health status improved in both groups at day 30 compared with baseline: IPC (mean difference 13.11; p=0.001) and chest drain (mean difference 10.11; p=0.001). However, there was no significant between-group difference at day 30 (mean intergroup difference in baseline-adjusted global health status 2.06, 95% CI -5.86-9.99; p=0.61), day 60 or day 90. No significant differences were identified between groups in breathlessness and chest pain scores. All chest drain arm patients were admitted (median length of stay 4 days); seven patients in the IPC arm required intervention-related hospitalisation. CONCLUSIONS: While HRQoL significantly improved in both groups, there were no differences in patient-reported global health status at 30 days. The outpatient pathway using an IPC was not superior to inpatient treatment with a chest drain.

Reports on vascular catheter-associated thromboembolic events in a burn unit - a gap in the literature?

Indwelling intravascular catheters are important tools in the care of critically ill patients; however, they have an inherent risk of infection or thromboembolic events. Reports on catheter associated thromboembolic events in burn units are rare, despite being well recognized that burn patients bear an increased baseline risk for thromboembolic events. We describe two catheter-associated thromboembolic complications in burn patients in a burn unit and the morbidity associated with these events. Patients with endovascular catheters in burn units may be at increased risk for severe thromboembolic events associated with intravascular catheters, but specific guidelines for prevention and management of these patients are still missing.

[Fungal peritoneal dialysis catheter-related exit-site infection combined with tunnel infection: A case report].

Peritoneal dialysis (PD) catheter-related infection (i.e. exit-site infection and tunnel infection) is one of the main causes of PD-related peritonitis. If it cannot be controlled effectively, it could lead to PD technique failure. Therefore, timely and effective diagnosis and treatment and active prevention so as to reduce PD catheter-related infection is an important treatment goal in PD patients. PD catheter exit-site infection (ESI) and tunnel infection can be caused by a variety of microorganisms, mainly bacteria, while fungi are very rare. Few public data can be used to guide treatment of PD catheter-related fungal infection, and there is no related report in China till now. Once fungal peritonitis occurred, the patient can only withdraw from PD treatment. Here, we report a case of fungal PD catheter ESI combined with tunnel infection which was successfully diagnosed and treated in our PD center. A 71-year-old woman came to clinic because of "PD for 5 years, secretions from exit site for 8 days and aggravation for 1 day". The patient suffered from peritonitis, ESI and tunnel infection for many times in the past 5 years, involving a variety of pathogens. Eight days before, she found white viscous discharge from exit site. The subcutaneous cuff completely came out of it and rubbed its skin. The Schaefer exit-site score was 3 points. Due to the suspected ESI 2 months before, the discharge swab for bacterial culture was positive for Pseudomonas aeruginosa, so the exit site swab for bacterial culture was done again, and gentamicin injection was applied topically once a day for empirical treatment. The exit site was evaluated one day before: The subcutaneous tunnel was significantly swollen and slightly tender at 2.5 cm away from the exit site, and with white medium amount of viscous secretions. The exit-site score increased to 4 points. Routine test of dialysis effluent was (-). The bacterial culture of the exit-site discharge was rechecked twice, and Candida parapsilosis was positive for two times, so the diagnosis of fungal PD catheter ESI combined with tunnel infection was clear. Immediately we searched for the causes of ESI and tunnel infection. We found that the patient had a suspicious history of gray toenail on the foot. The toenail smear was positive for fungi and visible hyphae. She washed feet with hands every day, and washed clothes on a low bench every day, which made the exit-site and tunnel squeezed for a long time. Based on the above causes, we gave her comprehensive treatment as follows: For ESI and tunnel fungal infections, fluco-nazole was used systemically according to the drug sensitivity results, and miconazole cream was applied to the exit-site locally. For the subcutaneous cuff that came out completely, daily iodophor disinfection was given locally. At the same time, local antifungal treatment was given to the foot. We followed up closely during treatment, evaluated the exit-site every 2-3 days, and took photos of the exit-site to dynamically observe the effect. After 14 days of treatment, the exit-site score continued to be 0-1, the bacterial culture of the exit-site was negative, the cuff culture was negative, and the tunnel B-ultrasound was normal. The patient had been followed up regularly once a month for 60 months, no ESI and tunnel infection occurred. Fungal PD catheter ESI and tunnel infection are rare complications of PD. When the standard anti-infection treatment is ineffective, the possibility of fungal infection should be considered, so as to avoid prolonged use of antibiotics, aggravating fungal infection, and even progressing to fungal peritonitis, leading to withdrawal from PD. Accurate exit-site evaluation is helpful for timely diagnosis and early treatment of ESI and tunnel infection. The exit-site discharge culture and drug sensitivity test before treatment are helpful to identify the pathogen and adjust subsequent treatment. At the same time, repeated discharge culture is required in order to exclude positive fungal culture results caused by contamination. Once fungal catheter-related infection is diagnosed, we should search for possible causes actively, subsequent targeted and comprehensive treatment plays a decisive role for the prognosis of patients.

Recent insights into catheter-related urinary tract infections.

Urinary tract infections (UTIs) commonly develop in people with urinary catheters. Inserting a catheter can damage the urothelial barrier and trigger the formation of a biofilm on the catheter that allows bacteria direct access to the bladder. Biofilms also protect bacteria from the immune system and reduce antibiotic effectiveness. In addition, a growing literature suggests that the urinary tract harbours bacteria even in people with negative conventional cultures. The urinary microbiome is highly individual. Nevertheless, changes in the urinary microbiome may identify individuals at risk of UTIs and, for example, suggest that a catheter should be replaced more frequently and, in turn, avoid the need for antibiotics. This article outlines the importance of biofilms in the development of catheter-related UTIs and introduces the urinary microbiome.

Micropuncture Access Set Use During Implantation of Totally Implantable Venous Access Device May Reduce Upper Extremity DVT Incidence Among Patients Undergoing Chemotherapy for Colorectal Cancer.

BACKGROUND: The aim of this study was to compare the perioperative outcomes when using a micropuncture access set (MS) to those when using a conventional puncture set (CS) for implantation of totally implantable venous access device (TAVID). METHODS: A total of 314 patients undergoing chemotherapy for colorectal cancer were included between June 2015 and July 2018. Of these, 123 (39.2%) received TAVID implantation using MS and 191 patients (60.8%) received TAVID using CS. Perioperative outcomes and complications were compared between both groups. RESULTS: Baseline characteristics, including body mass index, American Society of Anesthesiologists score, cardiovascular disease, diabetes mellitus, and hyperlipidemia, were not significantly different between the groups. Postoperative complications occurred in 25 patients (8.0%), and the rate and incidence of venous thrombosis were significantly higher in the CS group. There were no significant differences between the groups in other complications such as the rate of port site infection, deep vein thrombosis, obstruction, catheter dislocation, and skin complications (exposure). No incidence of catheter infection, port rotation, intraoperative bleeding, or pneumothorax was observed in this cohort. CONCLUSIONS: MS is a safe and feasible procedure and results in less thrombosis. MS may play an important role in improving outcomes for the implantation of TAVID.

[A Case of Malignant Pleural Effusion Implanted Subcutaneous Pleural Port].

A 74-year-old man with malignant pleural effusion due to recurrent gastric cancer underwent a failed pleurodesis. He subsequently underwent subcutaneous implantable pleural port implantation surgery followed by outpatient chemotherapy for 1 month. His disease progressed and he was unable to go to the hospital. He requested home care, so a nurse practitioner visited his home and drained the pleural effusion from the subcutaneous implantable pleural port. About 3 weeks after starting home care, he died at home. Pleurodesis is a common treatment for malignant pleural effusion; however, if a patient does not respond, long-term hospitalization is required due to manage port drainage. The subcutaneous implantable pleural port may aid provision of effective home care.

Intrathecal Baclofen Therapy in Patients With Multiple Sclerosis: Improved Outcomes and Reduced Costs Through Identification of Catheter Malfunction.

INTRODUCTION: Two patients previously implanted with intrathecal Baclofen (ITB) pumps for management of intractable spasticity due to multiple sclerosis (MS) were referred to our center for ongoing management of their spasticity. Initial evaluation of these patients revealed high levels of spasticity in the presence of ITB doses 10 times the average daily dose of our other MS patients. CLINICAL FACTS: High doses of ITB required frequent clinical visits and result in high drug and procedure costs. Both patients' daily doses were greater than 1000 mcg/day resulting in clinical visits every 1-2 months with drug and procedure costs ranging from 16 to 23 thousand dollars annually based on Medicare national average pricing for physician's office. Of the 59 MS patients receiving ITB therapy at our institution, the mean, median, and mode daily doses for ITB are 184, 115, and 159 mcg/day, respectively. The high ITB doses in these patients and poor spasticity control raised suspicion for pump/catheter malfunction and prompted immediate troubleshooting. FINDINGS: One patient's catheter was found to be disconnected from the pump and the other's catheter tip was outside the intrathecal space. In both cases, the patients were not receiving the therapy. After pump/catheter replacement, both patients received excellent clinical benefits from ITB at significantly lower daily doses. This reduction in dose resulted in decreased frequency of medication refills (twice annually) which resulted in decreased cost of care (12-19 thousand dollars savings annually per patient). DISCUSSION: These cases illustrate the need for early ITB pump troubleshooting to identify catheter problems, improve efficacy, and avoid unnecessary healthcare costs.

A hybrid process fidelity assessment in a home-based randomized clinical trial.

A process fidelity assessment was conducted as a nested study within a home-based randomized clinical trial teaching self-management to 101 long-term indwelling urinary catheter users in the treatment group. Our hybrid model combined external assessments (outside observations and tape recordings) with internal evaluation methods (through study nurse forms and notes) for a comprehensive process fidelity assessment. Barriers, patient-related issues, and nurse perspectives were identified demonstrating the complexity in home care intervention research. The complementary and synergistic approaches provided in-depth information about the context of the delivery and the impact of the intervention on study outcomes.

Correcting and sharing our complications. Misplacement of pigtail catheter, during a Robot Assisted Pyeloplasty. Clinical findings, diagnosis, possible causes and endoscopic treatment.

OBJECTIVE: Robotic assisted pyeloplasty (RAP) is rapidly adopted by surgeons around the world. We present a unique complication of the technique, consisting of pigtail misplacement, which was endoscopically resolved. We discuss the clinical findings, differential diagnosis and principles of endoscopic treatment. MATERIALS AND METHODS: A 41 years old female patients underwent transperitoneal right side RAP with the Hynes-Anderson technique for ureteropelvic junction obstruction. Pigtail was placed intraoperatively in an antegrade fashion. Post operative course appeared normal but Kidney-Ureterer-Bladder(KUB) X-ray, revealed a misplaced pigtail. Patient underwent a semirigid ureterorenoscopy demonstrating that the pigtail was exiting the collecting system in the rear line of suturing between continuous sutures. Pigtail was retrieved with a stone retrieval forceps with short upward motions in the renal pelvis under fluoroscopy and then removed from patient, in order to avoid stressing the anastomosis. No leakage was noted in fluoroscopy, a pigtail was correctly placed and patient recovery was uneventful. RESULTS: Retrograde pyelography was the key to accurate diagnosis and endoscopic treatment, because the exact point of exit and anastomosis integrity were established. Retrieval of the pigtail was the most challenging part. Lack of proper visualization and mobilization of the rear part of the anastomosis during surgery, combined with lack of tactile feedback, because of robotic instrumentation, were of critical importance in the manifestation of such a mishap. Endoscopy facilitated case resolve, but proper handling is required to protect the anastomosis. CONCLUSIONS: The introduction of novel techniques can carry the burden of novel complications. A surgeon must always keep in mind the complications inherent to the technique and at the same time the limitations of the equipment used, especially the lack of tactile feedback in robotic instrumentation.

A rare complication after renal transplantation: Forgotten stent.

In renal transplantation surgery, double J stents (DJS) are often used to reduce complications, protect the anastomosis between ureter and bladder, provide drainage in ureteral obstructions and enhance healing if there is an ureter injury. Urinary tract infections, hematuria and irritative voiding symptoms are the early complications of DJS. Migration, fragmentation, encrustation and rarely sepsis are among the late complications of DJS. In this report we describe a renal transplantation case whose DJS stent was forgotten because the patient did not attend the regular follow-up and noticed 5 years after surgery.

Therapeutic and prophylactic ethanol lock therapy in patients with bleeding disorders.

Obtaining a reliable venous access is a limiting factor for early initiation of clotting factor prophylaxis and immune tolerance induction. To circumvent this issue, central venous access devices (CVADs) are increasingly being used. Catheter-related infections (CRIs) remain the primary complication of insertion of CVAD. Thus, newer strategies for treatment and prevention of CRI are needed. Ethanol lock therapy (ELT) has been used to treat and prevent CRI in non-bleeding disorder patients. The aim of this study was to assess the efficacy of ELT in treating and preventing CRI in bleeding disorder patients. The medical charts of patients with bleeding disorders who underwent ELT for antimicrobial resistant CRIs were reviewed and data were analysed. ELT was effective in catheter salvage in 87% of patients with antimicrobial resistant CRI by a wide variety of pathogens. Prophylactic therapy with ethanol lock was associated with catheter dysfunction especially in mediports. ELT should be considered prior to removal of catheters in bleeding disorder patients with resistant CRIs. Further studies are needed for using prophylactic ethanol lock in prevention of CRIs in bleeding disorder patients.

Exhausting multiple hemodialysis access failures.

INTRODUCTION: Vascular access is often considered the Achilles heel the of hemodialysis because of its impact on morbidity, all cause mortality and finally costs of these patients. The most common complication of permanent hemodialysis (HD) vascular access is thrombosis, with some cases being related to hypercoagulability states. Antiphospholipid antibody syndrome (APAS) is a cause of increased thrombotic tendency, and this may complicate the management of such patients on HD. CASE REPORT: We describe a 41-year-old woman with end stage renal disease (ESRD) from Adult Polycystic Kidney Disease who was referred to our tertiary care center for treatment and selection of renal replacement therapy form. It was thought to initiate with peritoneal dialysis considering her actual conditions. She was putted on hemodialysis for several sessions, and a subclavian cathether was her first vascular access. The surgeon created an arterio-venous fistula which did not mature. After the implantation of the peritoneal cathether she started peritoneal dialysis and continued living with that for 2 years. She felt exhausted and because of a grave peritonitis episode accompanied with procedure failure and a long hospitalization she was transferred to hemodialysis. Renal transplantation was not possible because she didn't have a kidney donation. She was maintained on regular HD, but her dialysis care was complicated by recurrent vascular access failures. She had multiple interventions for arterio-venous fistulas and grafts but almost all of them failed due to thrombosis to the extent that only one access site was available for her routine renal replacement treatment. A thorough thrombophilia screen confirmed the presence of antiphospholipid antibodies. A diagnosis of APAS was made and she was anticoagulated with warfarin. The AVG made in this last available site is still working from 18 months. If it fails we have no answers and solutions for her. CONCLUSION: The presence of APAS can complicate HD management by causing recurrent vascular access thrombosis and failure, and nephrologist must remain alert to this possibility. Checking and treating as soon as possible it's our future challenge.

The use of mini-invasive surgical techniques to treat refractory exit-site and tunnel infections in peritoneal dialysis patients: a clinical approach.

Peritoneal dialysis-(PD) related infections continue to be a major cause of morbidity and mortality in patients on PD. Although great advances have been made in the prevention and treatment of infectious complications over the past two decades, catheter-related infections represent a significant cause of technical failure in PD. Recent studies support the role of exit-site/tunnel infections in causing peritonitis. Peritonitis secondary to tunnel infection led to catheter loss in most cases. Thus, removing the catheter when exit-site/tunnel infection is refractory to medical therapy has been recommended. This approach requires interrupting PD and, after the placement of a central venous catheter, and transferring the patient to haemodialysis. In order to continue PD, simultaneous catheter removal and replacement of the PD catheter has been suggested. Although simultaneous catheter removal and replacement avoids temporary haemodialysis, it implies the removal/reinsertion of the catheter and the immediate initiation of PD with the risk of mechanical complications, such as leakage and malfunction. Hence, several mini-invasive surgical techniques, such as curettage, cuff-shaving, removal of the superficial cuff, and partial reimplantation of the catheter, have been proposed as rescue treatments. These procedures may allow the rescue of the catheter with a success rate of 70-100%. Therefore, in case of refractory exit-site/tunnel infection, a mini-invasive surgical revision should be considered before removing the catheter.

High C-reactive protein and number of previous episodes at diagnosis increase the risk of catheter removal in peritoneal dialysis-related peritonitis in children.

BACKGROUND: A minority of patients with peritonitis require removal of peritoneal dialysis (PD) catheters. We examined risk factors at diagnosis that could predict the removal of PD catheter before obtaining the results of treatment success in children with peritonitis. METHODS: We analyzed 156 peritonitis episodes in 57 pediatric PD patients. RESULTS: The peritonitis rate was 0.68 peritonitis episode per patient year. Catheter removal was required in 22 of 156. C-reactive protein (CRP) ≥ ×10 of upper limit at diagnosis and increased previous episode number were found to be associated with catheter removal (OR [95% CI] 6.4 [2.3-18.1], p = 0.001 and 3.8 [1.4-10.6], p = 0.009). CONCLUSION: These findings supported that CRP could be an early marker in predicting catheter removal even before obtaining the results of treatment success. Furthermore, it should be kept in mind that the risk of catheter removal is high in patients with high number of previous episodes especially of three or more.

Novel care bundle of established basic and practical approaches greatly reduces urinary tract infections in nursing facility residents without indwelling catheters.

BACKGROUND: Residents in nursing facilities (NFs) are at greater risk of developing urinary tract infections (UTIs) with higher hospitalizations and costs than people living in communities. These residents also have increased likelihood of uroseptic shock and death. The objective of the study was to prevent UTIs and to reduce UTI-associated costs among NF residents. METHODS: Quality assurance performance improvement initiative conducted between April 1, 2018 and March 31, 2022 at a large skilled NF. Participants were 262 residents newly diagnosed with UTIs without indwelling catheters. The initiative consisted of (1) a 12-month baseline; (2) a 12-month intervention; and (3) a 24-month follow-up. A novel care bundle which included staff's hand hygiene monitoring, residents' hydration status, effective incontinence and perineal care, and in-house UTI treatment was implemented during the intervention. The plan-do-study-act cycle was used to gauge its effectiveness. RESULTS: Quarterly UTI rates decreased from 4.2% at baseline to 0.9% at follow-up, a 79% reduction (P < .001). All 262 residents were treated in-house with no UTI-related hospitalizations. Antibiotic prescriptions fell from 373 at baseline down to 143 at follow-up, a 62% reduction. Facility costs decreased from $42,188 at baseline to $8,281 at follow-up (P < 0.001). CONCLUSION: This bundle was very effective in preventing UTIs and reducing UTI-associated costs. Its use in other NFs is encouraged to determine suitability elsewhere.
