Preoperative nutritional status assessed using the CONUT tool and its relationship with the appearance of major postoperative complications.

INTRODUCTION: Malnutrition is a risk factor for the appearance of major postoperative complications; therefore, early identification and perioperative optimization of surgical patients may improve postoperative outcomes. The objective of our study was to determine the prevalence of moderate or high under nutrition alerts in patients undergoing major non-cardiac surgery, and their relationship with the appearance of major postoperative complications. Nutritional status was calculated using the CONUT tool. MATERIAL AND METHODS: A retrospective observational study in 190 patients who underwent major non-cardiac surgery over two consecutive years. Preoperative nutritional status was calculated using CONUT, and the patients' medical records were reviewed to determine their epidemiological characteristics and major complications. RESULTS: The under nutrition alert was moderate in 17% of patients, and high in 10%. A high under nutrition alert was an independent risk factor for treatment with vasoactive drugs (OR 3.58; 95% CI 1.18-10.89; p = 0.025), respiratory support (OR 7.63; 95% CI 1.25-46.43; p = 0.027), renal support (OR 23.29; 95% CI 2.0-271.08; p = 0.012), prolonged hospital stay (Coef 20.16; 95% CI 2.10-38.22; p = 0.029) and higher in-hospital mortality (OR 7.15; 95% CI 1.31-39.02; p = 0.023). CONCLUSIONS: In total, 10% of patients who underwent major non-cardiac surgery presented serious preoperative deterioration in their nutritional status. A high under nutrition alert was an independent risk factor for the appearance of major postoperative complications.

Preventable stillbirths in India and Pakistan: a prospective, observational study.

OBJECTIVE: Stillbirths occur 10-20 times more frequently in low-income settings compared with high-income settings. We created a methodology to define the proportion of stillbirths that are potentially preventable in low-income settings and applied it to stillbirths in sites in India and Pakistan. DESIGN: Prospective observational study. SETTING: Three maternity hospitals in Davangere, India and a large public hospital in Karachi, Pakistan. POPULATION: All cases of stillbirth at ≥20 weeks of gestation occurring from July 2018 to February 2020 were screened for participation; 872 stillbirths were included in this analysis. METHODS: We prospectively defined the conditions and gestational ages that defined the stillbirth cases considered potentially preventable. Informed consent was sought from the parent(s) once the stillbirth was identified, either before or soon after delivery. All information available, including obstetric and medical history, clinical course, fetal heart sounds on admission, the presence of maceration as well as examination of the stillbirth after delivery, histology, and polymerase chain reaction for infectious pathogens of the placenta and various fetal tissues, was used to assess whether a stillbirth was potentially preventable. MAIN OUTCOME MEASURES: Whether a stillbirth was determined to be potentially preventable and the criteria for assignment to those categories. RESULTS: Of 984 enrolled, 872 stillbirths at ≥20 weeks of gestation met the inclusion criteria and were included; of these, 55.5% were deemed to be potentially preventable. Of the 649 stillbirths at ≥28 weeks of gestation and ≥1000 g birthweight, 73.5% were considered potentially preventable. The most common conditions associated with a potentially preventable stillbirth at ≥28 weeks of gestation and ≥1000 g birthweight were small for gestational age (SGA) (52.8%), maternal hypertension (50.2%), antepartum haemorrhage (31.4%) and death that occurred after hospital admission (15.7%). CONCLUSIONS: Most stillbirths in these sites were deemed preventable and were often associated with maternal hypertension, antepartum haemorrhage, SGA and intrapartum demise. TWEETABLE ABSTRACT: Most stillbirths are preventable by better care for women with hypertension, growth restriction and antepartum haemorrhage.

Incidence of electrocardiographic alterations in the preoperative period of non-cardiac surgery.

BACKGROUND: The electrocardiogram is the most widely used test to assess cardiovascular risk during the preoperative period. The objective of the present study is to evaluate the incidence of electrocardiographic alterations in the general population scheduled for non-cardiac surgery and to determine if the age greater than or equal to 65 years or the revised cardiac risk index ≥1 represent a risk factor for presenting these alterations. MATERIAL AND METHODS: Over a period of one month, all preoperative electrocardiograms (ECG) from the anesthesia clinic were analyzed. Various epidemiological data were collected and the revised cardiac risk index was calculated. Major alterations were defined as those requiring Cardiology follow-up. RESULTS: 476 patients were recruited, of whom 40.8% were ≥65 years, 32.6% had HTN, 14.4% DM and 27.9% dyslipidemia. 16.16% of the patients had a Lee Index ≥1. Of the entire sample, 80.5% had a normal ECG, 6.5% minor alterations and 13.0% major alterations. In the multivariate analysis, age ≥65 years and the presence of HTN were shown as independent risk factors for presenting alterations in the total and major ECG. The Lee index ≥1 was not associated with an increased risk of electrocardiographic abnormalities. CONCLUSIONS: Patients ≥65 years old and those with HTN are at greater risk of presenting major electrocardiographic abnormalities, so we recommend including the ECG as a routine diagnostic test in the preoperative period of non-cardiac surgery.

[Evaluation of training on the programs to optimize antimicrobial use in medical residents of the province of Las Palmas]. / Evaluación de la formación sobre el programa de optimización del uso de antimicrobianos en médicos residentes de la provincia de Las Palmas.

OBJECTIVE: Antibiotic resistance is a threat to global public health. This situation makes essential to establish programs to optimize antimicrobial use (PROA). Training needs are identified in the PROA of resident physicians and the results of the analysis of the associations between study variables and training in the rational and prudent use of antibiotics are presented in this analysis. METHODS: Cross-sectional and analytical study through a self-administered questionnaire to a group of 506 medical residents of the province of Las Palmas. The association between resident's characteristics and PROA training was calculated through logistic regression. RESULTS: The associations between response variance and speciality were observed in most of the core component analysis (opportunity p=0.003, training p=0.007, motivation p=0.055 and hand hygiene p=0.044), followed by variance according to sex (capacity p=0.028, theoretical knowledge p=0.013, hand hygiene p=0.002). Very few differences were associated with age (capacity p=0.051 and hand hygiene p=0.054) or the year of expertise (hand hygiene p=0.032). CONCLUSIONS: The main training needs of resident physicians include one health, motivation, training, hand hygiene and information. The type of speciality followed by sex are the most important determinants on antibiotic use and resistance for resident physicians.

Effectiveness of a bundle of measures for reducing central line-associated bloodstream infections. / Efectividad de un paquete de medidas para reducir las bacteriemias asociadas a catéter venoso central.

INTRODUCTION: Catheter-associated infections are the main cause of nosocomial bacteremia. The main objective of this study was to demonstrate a possible decrease in CLABSI rates in perioperative environment after the implementation of a bundle of measures. Secondary objective was to determine which factors were associated with an increased risk of CLABSI, after the implementation of the bundle. METHODS: Insertion bundle consisted of: subclavian vein as access of choice, disinfection with alcoholic 2% chlorhexidine, central-line full body drapes, sterile ultrasound probe-cable covers and insertion check-list. Cumulative Incidence (CI) and Incidence Density Rate (IR) of CLABSIs were compared before and after the intervention. Associations between patient or CVC characteristic and CLABSI were summarized with odds ratios and 95% confidence interval, obtained from multiple logistic regression, adjusting for age, sex, comorbidities and days with CVC. RESULTS: Before implementing the bundle, from January to November 2016, CI of CLABSI was 5.05% and IR was 5.17 ‰. In the same period of 2018, CI of CLABSI was 2.28% and IR was 2.27 ‰, which means a reduction of 54.8% in CI (P=.072) and of 56% in IR (P=.068) In multivariable analyses, replacement of CVC was associated with a higher risk of CLABSI (OR 11.01, 95%CI 2.03-59.60, P=.005), as well as 2 or more catheterizations (OR 10.05, 95%CI 1.77-57.16, P=.009), and parenteral nutrition (OR 23.37, 95%CI 4.37-124.91, P<.001). CONCLUSIONS: CLABSI rates decreased after the implementation of the insertion bundle. CVC replacement, 2 or more catheterizations and parenteral nutrition were associated with CLABSI after bundle implementation.

Initial clinical outcomes and prognostic variables in the implementation of a Code Sepsis in a high complexity University Hospital.

OBJECTIVE: To assess the impact of the first months of application of a Code Sepsis in a high complexity hospital, analyzing patient´s epidemiological and clinical characteristics and prognostic factors. METHODS: A long-term observational study was carried out throughout a consecutive period of seven months (February 2015 - September 2015). The relationship with mortality of risk factors, and analytic values was analyzed using uni- and multivariate analyses. RESULTS: A total of 237 patients were included. The in-hospital mortality was 24% at 30 days and 27% at 60 days. The mortality of patients admitted to Critical Care Units was 30%. Significant differences were found between the patients who died and those who survived in mean levels of creatinine (2.30 vs 1.46 mg/dL, p <0.05), lactic acid (6.10 vs 2.62 mmol/L, p <0.05) and procalcitonin (23.27 vs 12.73 mg/dL, p<0.05). A statistically significant linear trend was found between SOFA scale rating and mortality (p<0.05). In the multivariate analysis additional independent risk factors associated with death were identified: age > 65 years (OR 5.33, p <0.05), lactic acid > 3 mmol/L (OR 5,85, p <0,05), creatinine > 1,2 mgr /dL (OR 4,54, p <0,05) and shock (OR 6,57, P <0,05). CONCLUSIONS: The epidemiological, clinical and mortality characteristics of the patients in our series are similar to the best published in the literature. The study has identified several markers that could be useful at a local level to estimate risk of death in septic patients. Studies like this one are necessary to make improvements in the Code Sepsis programs.
