Pathogen distribution and risk factors for urinary tract infection in infants and young children with retained double-J catheters.

ObjectivesTo investigate the pathogens and potential risk factors for urinary tract infection (UTI) in patients with retained double-J catheters (DJCs).MethodsIn total, 107 infants and young children with DJCs were included in this retrospective analysis. Patients were included in the infection group (n = 30) or non-infection group (n = 77), according to UTI presence or absence. The species and characteristics of pathogens were investigated, and the clinical features of the patients were recorded for further analysis.ResultsGram-negative bacilli were the most common causative pathogens (69.2%), among which Escherichia coli was most frequent (38.5%). The second most common causative pathogens were Gram-positive cocci (28.2%), among which Enterococcus faecalis was most frequent (10.3%). UTIs among patients in this study were associated with the following factors: catheter retention (long-term) (odds ratio [OR] = 2.514, 95% confidence interval [CI] = 1.176–5.373), sex (male) (OR = 2.966, 95% CI = 1.032–8.529), DJC retention (long-term) (OR = 1.869, 95% CI = 1.194–2.926), and DJC number (unilateral) (OR = 0.309, 95% CI = 0.103–0.922).ConclusionsInfants and young children with DJCs were likely to experience UTIs, mainly caused by Gram-negative bacilli. Long-term catheter retention or DJC retention, male sex, and bilateral DJC retention were risk factors for UTI.

Relationship between Stress Hyperglycemia and Catheter-related Urinary Tract Infection in Stroke Patients

Objective To verify the relationship between catheter-related urinary tract infection(CAUTI)and stress hyperglycemia during catheter retention in stroke patients. Methods We used nosocomial infection monitoring system to track the status of CAUTI in stroke patients in a hospital.The study cohort was all the patients who received retention catheterization from January 2016 to March 2020.According to the nested case-control design,multivariate logistic regression analysis was performed to explore the relationship between stress hyperglycemia and CAUTI in stroke patients with indwelling catheter. Results A total of 322 cases of CAUTI and 644 cases of non-CAUTI were enrolled in this study.The length of stay in the case group was(20.68 ± 3.73)d,significantly longer than that[(13.00 ± 4.01)d]in the control group(t=29.473,P <0.001).Compared with non-stress hyperglycemia,stress hyperglycemia posed a higher risk of CAUTI in the stroke patients with indwelling catheter(OR=2.020,95% CI=1.447-2.821,P=0.000)and led to the higher incidence of CAUTI in one thousand days(P<0.001). Conclusion Stress hyperglycemia in the stroke patients with indwelling catheter can significantly increase the risk of CAUTI.

Open and laparoscopic inguinal mesh repair: Hospital stay and Complications

Conservative treatment means living with the hernia, making lifestyle changes and watching for changes to the hernia. Lifestyle changes may include giving up smoking and avoiding heavy lifting, or wearing a special belt called a 'truss'. Hernia control has been reported in about 30% of patients. Complications associated with the use of a truss include testicular atrophy, ilioinguinal or femoral neuritis, and hernia incarceration. Patients with clinical evidence of inguinal hernia were admitted and were subjected to full history and examination, routine investigations like complete blood count, blood sugar level, serum creatinine, chest X-ray, ECG etc. Additional investigations like abdominal ultrasonography, CT scan of abdomen were done in cases with equivocal findings and suspected of other pathologies. Inclusion and exclusion criteria were defined and strictly adhered to in selecting the cases to be included in the study. Among the 30 cases that underwent open mesh repair, 3 cases required urethral catheterization for urinary retention, 3 cases suffered chronic pain, 2 cases had wound related complications and 1 had wound infection.

Risk Factors of PICC-Related Venous Thrombosis in Breast Cancer Patients Undergoing Chemotherapy.

BackgroundTo analyze the risk factors of a peripherally inserted central catheter (PICC)-related venous thrombosis in patients with breast cancer undergoing chemotherapy and explore its preventive measures.MethodsData of 780 patients with breast cancer who underwent PICC chemotherapy in our hospital from January 2014 to June 2015 were retrospectively analyzed. The incidence of catheter-related thrombosis was observed, and related factors of venous thrombosis were analyzed.ResultsAmong the 780 patients with breast cancer, 36 developed PICC-related venous thrombosis. The incidence of which was 4.62% (36/780). The PICC retention time ranged between 60 and 136 days, and the median time was 92 days. Thrombosis was found to occur within seven days after catheterization in three patients (8.33%), between 7 and 30 days in 18 patients (50%), between 31 and 92 days in 12 patients (33.3%), and ≥92 days in three patients (8.33%). Basilic vein puncture-induced thrombosis occurred in 25 patients (3.68%), and median cubital vein and cephalic vein puncture-induced thrombosis occurred in 11 patients (10.78%). The difference was statistically significant (P = 0.001). Thrombosis was not associated with age, punctured limb, platelet count, or chemotherapy drugs (P > 0.05).ConclusionBlood vessel puncture was the main factor that affected PICC-related thrombosis in breast cancer chemotherapy. The basilic vein should be the primary choice for blood vessel puncture. Prolonged catheter retention does not increase the risk of thrombosis.

Development of a more clinically relevant bladder and urethral model for catheter testing

This paper sets out the rationale and design for a more physiologically representative bladder/urethral model than the current rigid funnel industry standard. We suggest this flexible model can better serve as a basis for evaluating new catheters. We investigated the parameters and the validation tests required to construct and test with more flexible materials. The protocol includes static and impact force tests, while measuring internal retention balloon pressure. We have designed a flexible elastomer bladder floor and urethral model and tested it with a Foley balloon catheter. The tests showed that the model could hold the catheter with static loads up to 0.7 kg, but that the catheter was pulled out by impact forces from dropped weights. The Foley catheter design and its associated standards make no provision to mitigate urethral injury in the surprisingly common event of removal with a filled balloon. Our design is a more realistic model for testing retention and extraction characteristics of a urethral catheter. Validation tests have confirmed the feasibility of measuring urethral dilation and balloon pressure, both under traction and during progressive deflation. We suggest this model improves upon the current standard tests and will enable the design of safer catheters.

Spectrum of urological procedures in Yobe State University Teaching Hospital: an initial experience in a young west African hospital

Background: In auditing the surgical procedures of a hospital, services rendered to patients are reviewed using the data generated from the procedures, hence the outcome is used as a framework for improvement in future and capacity building. Objectives of the study were to analyze the indications for Urological procedures with the procedures performed at Yobe State University Teaching Hospital (YSUTH) and share our experience, with recommendation for future improvement.Methods: Retrospective hospital-based study on patients who had urological procedures done in YSUTH between March 2018 to April 2020. Urology patients that have not undergone any urological procedure were excluded from the study. Data obtained from the records in the operation theatre, emergency unit and medical record department of the hospital.Results: There were 185 patients with indications for surgery, constituting 41.0% of all general surgery patients. Male to female ratio was 8.7:1 and the median age range was 70-79 years. A sum of 212 urology procedures performed. Benign prostate hyperplasia (BPH) and prostatectomies were the commonest diagnoses and elective procedures respectively, while urethral stricture and bladder cancer were the 2nd and 3rd diagnose respectively. Urethral catheterization for urine retention in BPH was the commonest emergency procedure. Cystoscopy was the commonest day case and the commonest among endo-urology procedures.Conclusions: BPH, followed by urethral strictures and bladder cancers were the commonest diagnoses and indications for surgery. Urine retention in BPH is the commonest emergency requiring urthral catherization. Creation of dedicated day surgery unit and employment of permanentt consultant urologists and more health personnels relevant to urology, will improve the quality and quantity of services rendered.

Postoperative urinary retention: risk factors, bladder filling rate and time to catheterization: an observational study as part of a randomized controlled trial

BackgroundKnowledge of risk factors for postoperative urinary retention may guide appropriate and timely urinary catheterization. We aimed to determine independent risk factors for postoperative urinary catheterization in general surgical patients. In addition, we calculated bladder filling rate and assessed the time to spontaneous voiding or catheterization. We used the patients previously determined individual maximum bladder capacity as threshold for urinary catheterization.MethodsRisk factors for urinary catheterization were prospectively determined in 936 general surgical patients. Patients were at least 18 years of age and operated under general or spinal anesthesia without the need for an indwelling urinary catheter. Patients measured their maximum bladder capacity preoperatively at home, by voiding in a calibrated bowl after a strong urge that could no longer be ignored. Postoperatively, bladder volumes were assessed hourly with ultrasound. When patients reached their maximum bladder capacity and were unable to void, they were catheterized by the nursing staff. Bladder filling rate and time to catheterization were determined.ResultsSpinal anesthesia was the main independent modifiable risk factor for urinary catheterization (hyperbaric bupivacaine, relative risk 8.1, articaine RR 3.1). Unmodifiable risk factors were a maximum bladder capacity < 500 mL (RR 6.7), duration of surgery ≥ 60 min (RR 5.5), first scanned bladder volume at the Post Anesthesia Care Unit ≥250mL (RR 2.1), and age ≥ 60 years (RR 2.0). Urine production varied from 100 to 200 mL/h. Catheterization or spontaneous voiding took place approximately 4 h postoperatively.ConclusionSpinal anesthesia, longer surgery time, and older age are the main risk factors for urinary retention catheterization. Awareness of these risk factors, regularly bladder volume scanning (at least every 3 h) and using the individual maximum bladder capacity as volume threshold for urinary catheterization may avoid unnecessary urinary catheterization and will prevent bladder overdistention with the attendant risk of lower urinary tract injury.Trial registrationDutch Central Committee for Human Studies registered trial database: NL 21058.099.07.Current Controlled Trials database: Preventing Bladder Catheterization after an Operation under General or Spinal Anesthesia by Using the Patient’s Own Maximum Bladder Capacity as a Limit for Maximum Bladder Volume.

Factors Associated with the Success of Trial Without Catheter in Acute Urinary Retention Due to Benign Prostatic Hyperplasia

Purpose: This study aims to evaluate the parameters that can predict the success or failure of trial without catheter (TWOC) for acute urinary retention (AUR) due to benign prostatic hyperplasia (BPH). Materials and Methods: A prospective cohort study was conducted to include 73 medically treated patients with AUR due to BPH. All patients underwent catheterization and were started on alfuzosin (10 mg/day), followed by TWOC. Age, international prostate symptom score (IPSS), quality of life, prostate volume, and urine volume after catheterization were analyzed. Results: Patients' mean age was 74.23 ± 9.63 years; the first successful and failed TWOC was reported in 47 (64.4%) and 26 patients (35.6%), respectively. On the one hand, 89.4% of the patients continued medical treatment with alfuzosin (10 mg/day) in the first successful TWOC group. On the other hand, 30.8% showed the second successful TWOC and continued medical treatment in the first TWOC failure group. The uni- and multivariable analyses in this study showed that severe lower urinary tract symptoms (IPSS ≥20 points), prostatic pain during digital rectal examination (DRE), high urine volume after catheterization (≥950 mL), and high blood urea (≥4.55 mmol/L) were the predictive factors of TWOC failure. Conclusion: Severe lower urinary tract symptoms, prostatic pain during DRE, large urine volume after catheterization, and high blood urea are the predictive factors for TWOC failure in AUR due to BPH.

The Necessity of Postoperative Bladder Training by Intermittent Clamping: a Urologist’s View

The aim of the study is to evaluate the feasibility of postoperative bladder training by intermittent clamping. Urinary catheterization is a common technique in clinical practice. However, there is no consensus on its management prior to the removal of the indwelling catheter in postoperative situations. This review illustrates that bladder training by intermittent clamping prior to the removal of urinary catheters is not necessary. Additionally, intermittent clamping of urinary catheter might carry the risk of complications such as prolonging urinary catheter retention, urinary tract infection, and perfusion-reperfusion injury in bladder tissues.

Bipolar radiofrequency thermotherapy treatment of the prostate in urinary catheter-dependent men.

In this study, for the first time in the literature, we evaluated patients with benign prostatic hyperplasia (BPH) who had undergone permanent urinary catheterization for urinary retention and who were treated with radiofrequency (RF) thermotherapy as an alternative method due to their inoperability based on the high risk associated with anesthesia. We aimed to investigate these patients' posttreatment parameters concerning the catheter-free rates, quality of life (QoL) changes, and retrospective treatment efficacy. RF thermotherapy was applied to 62 permanent patients catheterized within the last 3 months due to urinary retention. The follow-up data of the patients were retrospectively analyzed. The patients who were free of catheters and those who required permanent catheterization were determined. The changes in the International Prostate Symptom Score (IPSS), QoL, postvoiding residue (PVR), and maximal flow rate (Qmax ) values were analyzed. A total of 52 patients were evaluated in terms of treatment success in relation to the elimination of the need for a urinary catheter, which was calculated as 73.07%. The Qmax , IPSS, QoL, and PVR values of 38 patients who no longer required a catheter were monitored for 24 months, and statistically significant changes were observed in all parameters. Bipolar RF thermotherapy was found to be beneficial for men dependent on catheters due to BPH. It can be recommended as a safe, minimally invasive treatment method for elderly patients with a high anesthesia risk.

Efficacy and safety of laparoscopic radical hysterectomy for early cervical adenocarcinoma

Objective: To investigate the efficacy and safety of laparoscopic radical hysterectomy for early cervical adenocarcinoma. Methods: A retrospective observational study was performed by reviewing medical records of patients with staging Ⅰb1-Ⅱa2 International Federation of Gynecology and Obstetrics (FIGO, 2009) cervical adenocarcinoma who underwent laparoscopic or abdominal radical hysterectomy from 2007 to 2017 in the Cancer Hospital, Peking Union Medical College, Chinese Academy of Medical Sciences. The difference among clinicopathologic characteristics, surgery-related parameters and complications, and prognosis were analyzed between the laparoscopic group and abdominal group. Results: Two hundreds and ninety-three patients were included with 88 cases in laparoscopic group and 205 cases in abdominal group. （1） There was no significant difference in clinicopathologic characteristics between the two groups （all P>0.05）, including age, body mass index, menopause status, history of abdominal surgery, clinical stage, tumor diameter, neoadjuvant chemotherapy, differentiation, lymph-vascular space invasion, positive of surgical margin, parametrial invasion, and lymph node metastasis. But the abdominal group showed a higher proportion of deep stromal invasion (38.5% vs 25.0%, P<0.05). No significant difference was observed between two groups with number of lymph nodes resected, urinary catheter retention, short-term surgical complications (including ureteral injury, ileus, infection, hydronephrosis and poor wound healing), and long-term complications (including voiding dysfunction, defecation dysfunction and lower limb edema； all P>0.05）. （2） The laparoscopic group was significantly associated with a longer operation time [(260±51) minutes vs (244±53) minutes, P<0.05], but less bleeding (100 ml vs 300 ml, P<0.01), shorter hospital stay [(13±5) days vs (16±8) days, P<0.01] and lower incidence of lymphedema (12.5% vs 27.8%, P<0.01). （3） The 5-year progression-free survival (PFS; 85.7% vs 86.4%, P=0.971) and 5-year overall survival (OS; 91.4% vs 93.0%, P=0.657) of laparoscopic group were comparable to that of abdominal group. （4） Multivariate analysis demonstrated that lymph node metastasis (HR=2.44, 95%CI: 1.16-5.15, P=0.019) was independent poor prognostic factors related to PFS, while adenosquamous carcinoma (HR=2.54, 95%CI: 1.02-6.35, P=0.046), lymph-vascular space invasion (HR=3.86, 95%CI: 1.60-9.33, P=0.003) and lymph node metastasis (HR=5.92, 95%CI: 2.45-14.34, P<0.01) were independent poor prognostic factors related to OS. The laparoscopy surgery was not an independent poor prognostic factor (P=0.396). Conclusion: The laparoscopic radical hysterectomy for early cervical adenocarcinoma has comparable prognosis to abdominal radical hysterectomy with a higher surgery quality.

Microbial epidemiology and risk factors for relapse in gram-negative bacteria catheter-related bloodstream infection with a pilot prospective study in patients with catheter removal receiving short-duration of antibiotic therapy

BackgroundInfectious Diseases Society of America (IDSA) guidelines suggest 7–14 days’ duration of antibiotic treatment for uncomplicated Gram-negative bacteria (GNB) catheter-related bloodstream infection (CRBSI). The objectives of this study were to review microbial epidemiology, to determine rate and risk factors for relapse, and to compare clinical outcomes in patients receiving long- versus short-duration antibiotic therapy.MethodsA retrospective phase 1 study was conducted between January 2010 and October 2016 to review microbial epidemiology and to determine the incidence of and risk factors for relapse in patients with GNB CRBSI, according to the IDSA guidelines diagnostic criteria. In phase 2 of the study, patients without risk factors for relapse between November 2016 and October 2017 were prospectively recruited to receive antibiotic therapy for 7 days after catheter removal. Matched patients from the retrospective phase 1 study who had received antibiotic therapy for ≥14 days were selected as a phase 2 control group to compare outcomes.ResultsIn phase 1, three most common pathogens identified among 174 cases were Pseudomonas aeruginosa (22.0%), Klebsiella pneumoniae (16.7%), and Stenotrophomonas maltophilia (13.4%). Eighty-nine episodes of infection occurred while patients were receiving antibiotic therapy. Of 140 cases, the relapse rate was 6.4%. Catheter retention was the only risk factor strongly associated with relapse (odds ratio = 145.32; 95% confidence interval 12.66–1667.37, P < 0.001). In phase 2, 11 patients with catheter removal were prospectively recruited to receive short-duration therapy. The number of patients with relapse receiving long- or short-duration therapy was 1 (3%) and 0 (0%), respectively (P = 1.000).ConclusionsFor the management of patients with uncomplicated GNB CRBSI, empiric broad-spectrum antibiotic therapy with adequate coverage of P. aeruginosa should be chosen. Catheter removal should be performed to prevent relapse and shortening the duration of treatment could be considered.Trial registrationThai Clinical Trial Registry: TCTR20190914001.

A pilot randomized-controlled trial evaluating the erector spinae plane block in thoracic and breast surgery.

This pilot study evaluated the feasibility of investigating the effect of the erector spinae plane (ESP) block on the patient-centred outcomes of quality of recovery-15 (QoR-15), and brief pain inventory (BPI) in thoracic and breast surgery patients. In this randomized-controlled pilot trial, 82 patients undergoing video-assisted thoracoscopic surgery (n = 77) and mastectomy (n = 5) received either continuous ESP block with ropivacaine (ropivacaine group) or the same procedure with 0.9% saline (saline group). All patients received surgical intercostal block (thoracic surgery) or local anesthetic infiltration (breast surgery). Feasibility as the primary outcome was evaluated on recruitment (three patients per week), catheter retention (above 90% at 24 hr), and patient attrition (less than 10%). Secondary outcomes comprised of QoR-15, BPI, and opioid consumption. Recruitment rate was 1.8 patients per week. Catheters were retained in 77 patients (94%) at 24 hr. At three months, five patients were lost to follow-up (6%). At 24 hr compared with baseline, the ropivacaine group had a smaller decline in QoR-15 score (median difference, 14; 95% confidence interval [CI], 2 to 26; P = 0.02) and a smaller increase in BPI global score (median difference, 14; 95% CI, 0 to 24; P = 0.048). There was no difference in opioid consumption (P = 0.08). In this pilot study, the target recruitment rate was not met, but catheter retention and patient attrition rates were both satisfactory. A definitive trial with QoR-15 as the primary outcome would require 300 study participants. Australian New Zealand Clinical Trials Registry (ID12618000701224); registered 30 April 2018.

Can vancomycin lock therapy extend the retention time of infected long-term catheters?

We assessed the success rate of vancomycin catheter lock therapy (VLT) in combination with systemic antimicrobials in patients with staphylococcal catheter-related bloodstream infection (C-RBSI). Over a 6-year period, we retrospectively collected clinical and microbiological data from patients with long-term central venous catheters and staphylococcal C-RBSI who were treated with systemic antimicrobials and VLT. We then assessed the success rate of VLT based on two criteria: 1) catheter retention time>3months and 2) catheter in place until end of use. We found 217 staphylococcal C-RBSI episodes, 115 (53.0%) of which were managed with conservative therapy. Of these, 76 (66.1%) were treated with VLT (85.5% coagulase-negative staphylococci and 14.5% Staphylococcus aureus). The success rate of VLT was 42.1% with criterion 1 and 71.1% with criterion 2. We did not find statistically significant differences between success and failure in the majority of the clinical data recorded. We only found differences for crude mortality in criterion 1 and for parenteral nutrition in criterion 2. The success of catheter retention using VLT was moderate, reaching slightly more than 70% when the catheter was kept in place until the end of use.

Effects of comprehensive rehabilitation on complications and long-term prognoses of patients in vegetative and minimal consciousness states.

To understand the clinical characteristics, prognoses, and prognostic factors of vegetative state (VS) and minimal consciousness state (MCS) patients hospitalized for comprehensive rehabilitation. The data of VS and MCS patients admitted in the past six years were retrospectively analyzed. Age of onset, etiology, course of disease, complications, and retention of tracheal intubation, gastric tube, and urethral catheter were recorded. All patients were followed for one year after onset, and their Glasgow Outcome Scale (GOS) scores were assessed. Long-term prognostic factors were analyzed using logistic regression. The proportion of patients with traumatic brain injuries in the MCS group was higher than in the VS group (p<0.05), while hypoxic-ischemic encephalopathy accounted for a higher proportion in the VS group; the differences were statistically significant between the two groups. The occurrence of infection was the highest in both groups, followed by spasticity and epilepsy. The occurrence of other complications was slightly different between the two groups but did not reach statistical significance (p>0.05). Age, etiology, and consciousness at admission had a significant impact on the long-term prognoses of VS or MCS patients (p<0.05), and the age of onset was the most important factor (the highest OR). Infection, spasticity, and epilepsy are common complications in both VS and MCS patients. Recovery of consciousness after one year was shown to be affected by age, etiology, and consciousness at admission.

Usefulness of EQUAL Candida Score for predicting outcomes in patients with candidaemia: a retrospective cohort study

BackgroundThe European Confederation of Medical Mycology (ECMM) Quality of Clinical Candidaemia Management (EQUAL) score is a tool designed by the ECMM to measure guideline adherence. The current study investigated the association between EQUAL scores and clinical outcomes. MethodsThis retrospective study was conducted in three hospitals in Taiwan. Patients with candidaemia between January 2014 and July 2018 were enrolled. Guideline adherence was evaluated using EQUAL score indicators. Clinical outcomes and predictors of 30-day mortality were investigated. ResultsA total of 384 patients were enrolled. The overall mean EQUAL score was 8.91 ± 3.42 (9.42 ± 3.60 in survivors vs. 8.10 ± 2.94 in non-survivors, p < 0.001). Higher scores were positively correlated with survival (p < 0.001). Scores of 16–22 indicated the highest survival rates (p for trend <0.001). The Kaplan–Meier plot revealed that patients with EQUAL scores ≥10 exhibited significantly higher survival rates (p < 0.001) than those with scores <10. Multivariable analysis revealed that EQUAL scores ≥10 (odds ratio (OR) 0.37, 95% confidence interval (CI) 0.19–0.74), advanced age (OR 1.02, 95% CI 1.00–1.04), septic shock (OR 4.42, 95% CI 2.09–9.36), high sequential organ failure assessment scores (OR 4.28, 95% CI 2.15–8.52), intravascular catheter-related source (OR 0.42, 95% CI 0.19–0.94) and central venous catheter retention (OR 5.41, 95% CI 2.06–14.24) were independent predictors of 30-day mortality. DiscussionGreater guideline adherence with a higher EQUAL score was significantly associated with survival. An EQUAL score cutoff point <10 predicted 30-day mortality.

68 Urinary Catheterisation in Trauma and Orthopaedic Patients

Abstract Background The use of urinary catheterisation in neck of femur fracture patients is often debated as common best practice to manage and appropriate fluid assessment. Routine catheterisation increases the risk bacteraemia, genitourinary injury, worsening mobility, risk of pressure sores and predisposition to delirium and falls. There is a need for increased awareness of urinary catheterisation management in conjunction with healthcare-associated infections. NHS improvement has issued a letter aiming to half healthcare-associated Gram-negative bacteraemia, the majority of which is catheter-related. This project aims to identify barriers to safe catheter care in the orthopaedic population; by determining if management of urinary catheters is complaint with NICE quality standards (QS61). Introduction Appropriate perioperative care can help manage the associated risk of neck of femur fractures. The British Hip Society and British Orthopaedic Association have provided little guidance on postoperative care and risk management. Appropriate catheter care will improve overall patient care but reducing mortality and associated morbidity, by shortening stay by early mobilisation and management of complications. Methods All catheterised trauma and orthopaedic patients in a district general hospital over one month (February) were included 67% of which had sustained neck of femur fractures. Data from nursing and doctors’ records on the following parameters were collected: demographics, the reason of admission, indication/location for catheterisation and responsible clinician; the number of days catheterised, the reason for the retention of catheterisation and management of suspected/confirmed catheter-related infection. Data were collected in April following the implementation. Intervention A urinary care pathway was launched based on the HOUDINI algorithm and educational seminars for medical and nursing staff were conducted. Results Mean age of patients was 78. Initial data was suggestive of poor documentation and prolonged, inappropriate retention of urinary catheterisation and not in accordance with current guidance. Data was recollected in April after the launch of the pathway; data was indicative of marginal improvement of catheter care management, reduced time of catheter retention, improved documentation likelihood of review. Conclusions Incorporating a catheter care pathway in managing orthopaedic patients has shown improvement in the overall documentation and management of urinary catheterisation. Despite this improvement demonstrated, implementation of the pathway is still substandard. This pathway will be incorporated into an innovative integrated neck of femur pathway in June.

A Retrospective Study on Risk Factors for Urinary Tract Infection in Patients with Intracranial Cerebral Hemorrhage.

Objective This study aimed to explore the risk factors of urinary tract infection (UTI) in patients with intracranial cerebral hemorrhage (ICH). Design This is a retrospective study, and a total of 77 patients with ICH consecutively admitted to the First Affiliated Hospital of USTC (Anhui Provincial Hospital, Hefei, China) during the period of August 2015 to August 2017 were included. The patients were divided into an UTI group (24 cases) and a non-UTI group (53 cases); patients with UTI were diagnosed according to clinical manifestations, recent urinary routines, and urine culture results. The following information in these two groups was recorded: age, sex, course of disease, side of paralysis, location and type of cerebral hemorrhage, disturbance of consciousness or not, the Brunnstrom stage of paralysed lower limbs, number of basic diseases, whether there were complications (tracheotomy, retention catheterization, pulmonary infection, pressure sore, deep venous thrombosis, etc.), whether rehabilitation interventions were conducted, blood routine, biochemistry index, DIC complete set, urine routine, and urine culture data. Univariate analysis and multivariate logistic regression analysis were used to examine the risk factors of UTI in patients with ICH. Results Univariate analysis showed that age, side of paralysis, disturbance of consciousness, the Brunnstrom stage of lower limbs, tracheotomies, retention catheterization, pulmonary infection, leukocyte count, neutrophil proportion, sodium, uric acid, D-dimer, and fibrinogen may be related to UTI in patients with ICH (P < 0.05). Regression analysis showed that age (OR (95% CI) = 1.207 (1.022–1.424), P < 0.05). Regression analysis showed that age (OR (95% CI) = 1.207 (1.022–1.424), P < 0.05). Regression analysis showed that age (OR (95% CI) = 1.207 (1.022–1.424), P < 0.05). Regression analysis showed that age (OR (95% CI) = 1.207 (1.022–1.424), Conclusions Increased age and high D-dimer are independent risk factors for UTI in patients with ICH, while right-sided paralysis is a protective factor for UTI in patients with ICH.

When radiology determines the success of removal of a retained epidural catheter: A case report

The epidural block is an anesthetic procedure that can have possible complications upon insertion or removal. Epidural catheter retention is a rare complication; its etiology may come from lateral migration with kinking of the catheter or from involvement with bone, ligamentous, muscular, vascular structures, or nerve roots. Up until today, there is not a standard approach to this complication; however, there are some recommendations for the management of retained epidural catheters. Here, we describe a case report of epidural catheter retention, in which we followed the published recommendations. Although computed tomography scanning may be the best option to visualize the anatomical position of the distal extremity of an epidural catheter, with this case report we intend to reinforce the fundamental contribution of the contrast radiograph in the successful catheter removal. Posteriorly, a protocol for clinical orientation of epidural catheter retention was developed in our institution.

Risk factors of peripherally inserted central catheter infection in patients with lung cancer undergoing chemotherapy

Objective To study the risk factors of peripherally inserted central catheter (PICC) infection in patients with lung cancer undergoing chemotherapy. Methods Medical records of 285 PICC patients with lung cancer treated in our hospital from February 2015 to October 2018 were retrospectively analyzed. The incidence of infection during PICC was recorded and the risk factors associated with infection were analyzed. Results Among 285 patients, there were 33 cases of PICC infection, with the infection rate of 11.58%. Catheterization in summer, the working time of catheterization staff less than 5 years, the times of catheterization more than 2 times, and the catheter retention time more than 30 days, diabetes history were independent risk factors for PICC infection (P<0.05). Conclusion Catheterization in summer, the working time of catheterization staff less than 5 years, the times of catheterization more than 2 times, and the catheter retention time more than 30 days, diabetes history were independent risk factors for PICC infection in lung cancer patients treated with chemotherapy.
