Peripheral intravenous catheter failure, nurse staffing levels and care complexity individual factors: A retrospective multicentre cohort study.

INTRODUCTION: Short peripheral intravenous catheter (PIVC) failure is a common complication that is generally underdiagnosed. Some studies have evaluated the factors associated with these complications, but the impact of care complexity individual factors and nurse staffing levels on PIVC failure is still to be assessed. The aim of this study was to determine the incidence and risk factors of PIVC failure in the public hospital system of the Southern Barcelona Metropolitan Area. METHODS: A retrospective multicentre observational cohort study of hospitalised adult patients was conducted in two public hospitals in Barcelona from 1st January 2016 to 31st December 2017. All adult patients admitted to the hospitalisation ward were included until the day of discharge. Patients were classified according to presence or absence of PIVC failure. The main outcomes were nurse staffing coverage (ATIC patient classification system) and 27-care complexity individual factors. Data were obtained from electronic health records in 2022. RESULTS: Of the 44,661 patients with a PIVC, catheter failure was recorded in 2,624 (5.9%) patients (2,577 [5.8%] phlebitis and 55 [0.1%] extravasation). PIVC failure was more frequent in female patients (42%), admitted to medical wards, unscheduled admissions, longer catheter dwell time (median 7.3 vs 2.2 days) and those with lower levels of nurse staffing coverage (mean 60.2 vs 71.5). Multivariate logistic regression analysis revealed that the female gender, medical ward admission, catheter dwell time, haemodynamic instability, uncontrolled pain, communication disorders, a high risk of haemorrhage, mental impairments, and a lack of caregiver support were independent factors associated with PIVC failure. Moreover, higher nurse staffing were a protective factor against PIVC failure (AUC, 0.73; 95% confidence interval [CI]: 0.72-0.74). CONCLUSION: About 6% of patients presented PIVC failure during hospitalisation. Several complexity factors were associated with PIVC failure and lower nurse staffing levels were identified in patients with PIVC failure. Institutions should consider that prior identification of care complexity individual factors and nurse staffing coverage could be associated with a reduced risk of PIVC failure.

Economic impact of a care bundle to prevent surgical site infection after craniotomy: a cost-analysis study.

BACKGROUND: Surgical site infections after craniotomy (SSI-CRAN) significantly impact patient outcomes and healthcare costs by increasing length of stay and readmission and reoperation rates. However, to our knowledge, no study has yet analysed the economic impact of a surgical care bundle for preventing SSI-CRAN. The aim is to analyse the hospital cost saving after implementation of a care bundle for the prevention of SSI-CRAN. METHODS: A retrospective cost-analysis was performed, considering two periods: pre-care bundle (2013-2015) and care bundle (2016-2017). A bottom-up approach was used to calculate the costs associated with infection in patients who developed a SSI-CRAN in comparison to those who did not, in both periods and on a patient-by-patient basis. The derived cost of SSI-CRAN was calculated considering: (1) cost of the antibiotic treatment, (2) cost of length of stay in the neurosurgery ward within the 1-year follow up period, (3) cost of the re-intervention, and (4) cost of the implant for cranial reconstruction, when necessary. RESULTS: A total of 595 patients were included in the pre-care bundle period and 422 in the care bundle period. Mean cost of a craniotomy procedure was approximately €8000, rising to €24,000 in the case of SSI-CRAN. Mean yearly hospital costs fell by €502,857 in the care bundle period (€714,886 vs. €212,029). Extra costs between periods were mainly due to increased length of hospital stay (€573,555.3 vs. €183,958.9; difference: €389,596.4), followed by the cost of implant for cranial reconstruction (€69,803.4 vs. €9,936; difference: €59,867.4). Overall, implementation of the care bundle saved the hospital €500,844.3/year. CONCLUSION: The implementation of a care bundle for SSI-CRAN had a significant economic impact. Hospitals should consider the deployment of this multimodal preventive strategy to reduce their SSI-CRAN rates, and also their costs.

A Care Bundle Intervention to Prevent Surgical Site Infections After a Craniotomy.

BACKGROUND: Although surgical site infections after a craniotomy (SSI-CRANs) are a serious problem that involves significant morbidity and costs, information on their prevention is scarce. We aimed to determine whether the implementation of a care bundle was effective in preventing SSI-CRANs. METHODS: A historical control study was used to evaluate the care bundle, which included a preoperative shower with 4% chlorhexidine soap, appropriate hair removal, adequate preoperative systemic antibiotic prophylaxis, the administration of 1 g of vancomycin powder into the subgaleal space before closing, and a postoperative dressing of the incisional surgical wound with a sterile absorbent cover. Patients were divided into 2 groups: preintervention (January 2013 to December 2015) and intervention (January 2016 to December 2017). The primary study end point was the incidence of SSI-CRANs within 1 year postsurgery. Propensity score matching was performed, and differences between the 2 study periods were assessed using Cox regression models. RESULTS: A total of 595 and 422 patients were included in the preintervention and intervention periods, respectively. The incidence of SSI-CRANs was lower in the intervention period (15.3% vs 3.5%; P < .001). Using a propensity score model, 421 pairs of patients were matched. The care bundle intervention was independently associated with a reduced incidence of SSI-CRANs (adjusted odds ratio, 0.23; 95% confidence interval, .13-.40; P < .001). CONCLUSIONS: The care bundle intervention was effective in reducing SSI-CRAN rates. The implementation of this multimodal preventive strategy should be considered in centers with high SSI-CRAN incidences.

The impact of flushing with pre-filled saline syringes on the incidence of peripheral venous catheter failure: A quasi-experimental study.

BACKGROUND: Short peripheral venous catheters are one of the most frequently used devices in hospitals. Peripheral venous catheter failure, defined as the unscheduled dysfunction of peripheral venous catheter, is common and frequently entails a new invasive procedure. Flushing the catheter maintains patency and could prolong peripheral venous catheter dwell time. The introduction of pre-filled saline flushing syringes as compared to manually filled saline flushing syringes could facilitate the frequency of catheter flushing, and subsequently it could reduce peripheral venous catheter failure rate. OBJECTIVE: To demonstrate differences in overall peripheral venous catheter failure rates before and after the introduction of pre-filled saline flushing syringes and to assess the risk factors for peripheral venous catheter failure. METHODS: Quasi-experimental design, before-and-after intervention study. Intervention: introduction of pre-filled saline syringes for flushing. Multicenter study conducted in medical and surgical wards of three European hospitals during a 9-month period (4 months pre-intervention, 5 months intervention). A multivariate Cox proportional model was used to identify factors associated with the occurrence of peripheral venous catheter failure. RESULTS: Data from 3853 peripheral venous catheters in 1915 patients were analyzed. Compared to pre-intervention period, a significant decrease in peripheral venous catheter failure rate was observed in the intervention period (57% vs 43.4%, p < 0.001). Independent factors associated with peripheral venous catheter failure were as follows: Charlson score ⩾4 (hazard ratio: 1.648; 95% confidence interval: 1.069-2.527), days of hospital stay ⩾10 (hazard ratio: 1.468; 95% confidence interval: 1.172-1.837), and catheter "D" (hazard ratio: 1.758; 95% confidence interval: 1.058-2.919). CONCLUSION: The use of pre-filled saline syringes significantly reduced peripheral venous catheter failure and increased catheter dwell time. Thus, it is important to reinforce the use of the pre-filled syringes for flushing to reduce the incidence of peripheral venous catheters' failure.

Risk factors for surgical site infection after craniotomy: a prospective cohort study.

Background: Although surgical site infection after craniotomy (SSI-CRAN) is a serious complication, risk factors for its development have not been well defined. We aim to identify the risk factors for developing SSI-CRAN in a large prospective cohort of adult patients undergoing craniotomy. Methods: A series of consecutive patients who underwent craniotomy at a university hospital from January 2013 to December 2015 were prospectively assessed. Demographic, epidemiological, surgical, clinical and microbiological data were collected. Patients were followed up in an active post-discharge surveillance programm e for up to one year after surgery. Multivariate analysis was carried out to identify independent risk factors for SSI-CRAN. Results: Among the 595 patients who underwent craniotomy, 91 (15.3%) episodes of SSI-CRAN were recorded, 67 (73.6%) of which were organ/space. Baseline demographic characteristics were similar among patients who developed SSI-CRAN and those who did not. The most frequent causative Gram-positive organisms were Cutibacterium acnes (23.1%) and Staphylococcus epidermidis (23.1%), whereas Enterobacter cloacae (12.1%) was the most commonly isolated Gram-negative agent. In the univariate analysis the factors associated with SSI-CRAN were ASA score > 2 (48.4% vs. 35.5% in SSI-CRAN and no SSI-CRAN respectively, p = 0.025), extrinsic tumour (28.6% vs. 19.2%, p = 0.05), and re-intervention (4.4% vs. 1.4%, p = < 0.001). In the multivariate analysis, ASA score > 2 (AOR: 2.26, 95% CI: 1.32-3.87; p = .003) and re-intervention (OR: 8.93, 95% CI: 5.33-14.96; p < 0.001) were the only factors independently associated with SSI-CRAN. Conclusion: The risk factors and causative agents of SSI-CRAN identified in this study should be considered in the design of preventive strategies aimed to reduce the incidence of this serious complication.

[The threat of the carbapenemase-producing enterobacteriaceae in Spain: positioning report of the SEIMC study groups, GEIH and GEMARA]. / La amenaza de las enterobacterias productoras de carbapenemasas en España: documento de posicionamiento de los grupos de estudio GEIH y GEMARA de la SEIMC.

The emergence and spread of carbapenemase-producing Enterobacteriaceae (CPE), as the current paradigm of extensive drug-resistance and multi-drug resistance to antibiotics, is a serious threat to patient health and public health. The increase in OXA-48- and VIM-1-producing Klebsiella pneumoniae isolates represents the greatest impact of CPE in Spain. This evidence has lead the members of a representative panel of the Spanish Study Groups of Nosocomial Infections and Mechanisms of Action and Resistance to Antimicrobials of the Spanish Society of Clinical Microbiology and Infectious Diseases (GEIH/GEMARA-SEIMC) to make a position statement expressing the need for: (i) definitive and coordinated action by all health professionals and authorities involved, and (ii) an adaptation of health systems to facilitate their early control and minimize their impact.

Prevalence and molecular characterization of methicillin-resistant Staphylococcus aureus ST398 resistant to tetracycline at a Spanish hospital over 12 years.

Methicillin-resistant Staphylococcus aureus (MRSA) ST398, associated with livestock animals, was described in 2003 as a new lineage infecting or colonizing humans. We evaluated the prevalence and molecular characteristics of MRSA ST398 isolated in the Hospital Universitari de Bellvitge from January 2000 to June 2011. Tetracycline resistant (Tet-R) MRSA isolates from single patients (pts) were screened by SmaI-pulsed field gel electrophoresis (PFGE). Nontypable MRSA strains by SmaI (NT Sma I)-MRSA were further analysed by ApaI-PFGE, spa, SCCmec, agr, MLST typing, and by DNA microarray hybridization. Among 164 pts harboring Tet-R MRSA, NT Sma I-MRSA ST398-agrI was found in 33 pts (20%). Although the first pt was detected in 2003, 22/33 pts (67%) were registered in the 2010-2011 period. Ten pts (30%) were infected and cancer was the most frequent underlying disease. In one case, death was due to MRSA-ST398-related infection. Five pulsotypes (A-E) were detected using ApaI-PFGE, with type A accounting for 76% of the strains. The majority of the studied isolates presented spa type t011 (70%) and SCCmec type V (88%). One strain was spa negative both by PCR and microarray analysis. Forty-nine percent of the studied isolates showed resistance to 3 or more antibiotic classes, in addition to beta-lactams. Ciprofloxacin resistance was 67%. Tet-R was mediated by tet(M) and tet(K) in 26 isolates. All isolates lacked Panton-Valentine Leukocidin production, as well as other significant toxins. This study displays the molecular features of MRSA-ST398 clone and shows the increase in tetracycline resistance together with arise in MRSA-ST398 isolates infecting or colonizing patients in our clinical setting.

Programas de optimización de uso de antimicrobianos (PROA) en hospitales españoles: documento de consenso GEIH-SEIMC, SEFH y SEMPSPH / Programs for optimizing the use of antibiotics (PROA) in Spanish hospitals: GEIH-SEIMC, SEFH and SEMPSPH consensus document

Los antimicrobianos son fármacos distintos al resto. Su eficacia en la reducción de la morbilidad y la mortalidad es muy superior a la de otros grupos de medicamentos. Por otra parte, son los únicos fármacos con efectos ecológicos, de manera que su administración puede contribuir a la aparición y diseminación de resistencias microbianas. Finalmente, son utilizados por médicos de prácticamente todas las especialidades. La actual complejidad en el manejo de las enfermedades infecciosas y del aumento de las resistencias hace imprescindible el establecimiento de programas de optimización del uso de antimicrobianos en los hospitales (PROA).Este documento de consenso define los objetivos de los PROA (mejorar los resultados clínicos de los pacientes con infecciones, minimizar los efectos adversos asociados a la utilización de antimicrobianos, incluyendo aquí las resistencias, y garantizar la utilización de tratamientos coste-eficaces) y establece recomendaciones para su implantación en los hospitales españoles. Las líneas maestras de las recomendaciones son: la constitución de un equipo multidisciplinario de antibióticos, dependiente de la Comisión de Infecciones. Los PROA necesitan ser considerados programas institucionales de los hospitales donde se desarrollen. Deben incluir objetivos específicos y resultados cuantificables en función de indicadores, y basarse en la realización de actividades encaminadas a mejorar el uso de antimicrobianos, principalmente mediante actividades formativas y medidas no impositivas de ayuda a la prescripción (AU)

The antimicrobial agents are unique drugs for several reasons. First, their efficacy is higher than other drugs in terms of reduction of morbidity and mortality. Also, antibiotics are the only group of drugs associated with ecological effects, because their administration may contribute to the emergence and spread of microbial resistance. Finally, they are used by almost all medical specialties. Appropriate use of antimicrobials is very complex because of the important advances in the management of infectious diseases and the spread of antibiotic resistance. Thus, the implementation of programs for optimizing the use of antibiotics in hospitals (called PROA in this document) is necessary. This consensus document defines the objectives of the PROA (namely, to improve the clinical results of patients with infections, to minimise the adverse events associated to the use of antimicrobials including the emergence and spread of antibiotic resistance, and to ensure the use of the most cost-efficacious treatments), and provides recommendations for the implementation of these programs in Spanish hospitals. The key aspects of the recommendations are as follows. Multidisciplinary antibiotic teams should be formed, under the auspices of the Infection Committees. The PROA need to be considered as part of institutional programs and the strategic objectives of the hospital. The PROA should include specific objectives based on measurable indicators, and activities aimed at improving the use of antimicrobials, mainly through educational activities and interventions based more on training activities directed to prescribers than just on restrictive measures (AU)
