Effectiveness and safety of non-invasive ventilation in the management of cardiogenic shock.

INTRODUCTION AND OBJECTIVES: Cardiogenic shock (CS) has long been considered a contraindication for the use of non-invasive ventilation (NIV). The main objective of this study was to analyze the effectiveness, measured as NIV success, in patients with respiratory failure due to CS. As secondary objective, we studied risk factors for NIV failure and compared the outcome of patients treated with NIV versus invasive mechanical ventilation (IMV). METHODS: Retrospective study on a prospective database, over a period of 25 years, of all consecutively patients admitted to an intensive care unit, with a diagnosis of CS and treated with NIV. A comparison was made between patients on NIV and patients on IMV using propensity score matching analysis. RESULTS: Three hundred patients were included, mean age 73.8 years, mean SAPS II 49. The main cause of CS was acute myocardial infarction (AMI): 164 (54.7%). NIV failure occurred in 153 (51%) cases. Independent factors for NIV failure included D/E stages of CS, AMI, NIV related complications, and being transferred from the ward. In the propensity analysis, hospital mortality (OR 1.69, 95% CI 1.09-2.63) and 1 year mortality (OR 1.61, 95% CI 1.04-2.51) was higher in IMV. Mortality was lower with NIV (vs. EIT-IMV) in C stage (10.1% vs. 32.9%; p<0.001) but did not differ in D stage or E stage. CONCLUSIONS: NIV seems to be relatively effective and safe in the treatment of early-stage CS.

Analysis of combined non-invasive respiratory support in the first six waves of the COVID-19 pandemic. Outcome according to the first respiratory support.

Introduction: COVID-19 can lead to acute respiratory failure (ARF) requiring admission to intensive care unit (ICU). This study analyzes COVID-19 patients admitted to the ICU, according to the initial respiratory support. Its main aim is to determine if the use of combination therapy: high-flow oxygen system with nasal cannula (HFNC) and non-invasive ventilation (NIV), is effective and safe in the treatment of these patients. Methods: Retrospective observational study with a prospective database. All COVID-19 patients, admitted to the ICU, between March 11, 2020, and February 12, 2022, and who required HFNC, NIV, or endotracheal intubation with invasive mechanical ventilation (ETI-IMV) were analyzed. HFNC failure was defined as therapeutic escalation to NIV, and NIV failure as the need for ETI-IMV or death in the ICU. The management of patients with non-invasive respiratory support included the use of combined therapy with different devices. The study period included the first six waves of the pandemic in Spain. Results: 424 patients were analyzed, of whom 12 (2.8%) received HFNC, 397 (93.7%) NIV and 15 (3.5%) ETI-IMV as first respiratory support. PaO2/FiO2 was 145 ± 30, 119 ± 26 and 117 ± 29 mmHg, respectively (p = 0.003). HFNC failed in 11 patients (91.7%), who then received NIV. Of the 408 patients treated with NIV, 353 (86.5%) received combination therapy with HFNC. In patients treated with NIV, there were 114 failures (27.9%). Only the value of SAPS II index (p = 0.001) and PaO2/FiO2 (p < 0.001) differed between the six analyzed waves, being the most altered values in the 3rd and 6th waves. Hospital mortality was 18.7%, not differing between the different waves (p = 0.713). Conclusions: Severe COVID-19 ARF can be effectively and safely treated with NIV combined with HFNC. The clinical characteristics of the patients did not change between the different waves, only showing a slight increase in severity in the 3rd and 6th waves, with no difference in the outcome.

Effectiveness of individualized inhaler technique training on low adherence (LowAd) in ambulatory patients with COPD and asthma.

To analyze whether there is improvement in adherence to inhaled treatment in patients with COPD and asthma after an educational intervention based on the teach-to-goal method. This is a prospective, non-randomized, single-group study, with intervention and before-after evaluation. The study population included 120 patients (67 females and 53 males) diagnosed with asthma (70.8%) and COPD (29.1%). The level of adherence (low and optimal) and the noncompliance behavior pattern (erratic, deliberate and unwitting) were determined by the Test of the adherence to Inhalers (TAI). This questionnaire allows you to determine the level of adherence and the types of noncompliance. Low Adherence (LowAd) was defined as a score less than 49 points. All patients received individualized educational inhaler technique intervention (IEITI). Before the IEITI, 67.5% of the patients had LowAd. Following IEITI, on week 24, LowAd was 55% (p = 0.024). Each patient can present one or more types of noncompliance. The most frequent type was forgetting to use the inhaler (erratic), 65.8%. The other types were deliberate: 43.3%, and unwitting: 57.5%. All of them had decreased on the final visit: 51.7% (p = 0.009), 25.8% (p = 0.002), 39.2% (p = 0.002). There were no significant differences in adherence between asthma and COPD patients at the start of the study. The only predicting factor of LowAd was the female gender. An individualized educational intervention, in ambulatory patients with COPD and asthma, in real-world clinical practice conditions, improves adherence to the inhaled treatment.

Is hypocapnia a risk factor for non-invasive ventilation failure in cardiogenic acute pulmonary edema?

INTRODUCTION AND PURPOSE: The impact of hypocapnia in the prognosis of cardiogenic acute pulmonary edema (CAPE) has not been sufficiently studied. The aim of this study was to analyse whether hypocapnia is a risk factor for non-invasive ventilation (NIV) failure and hospital mortality, in CAPE patients CAPE. METHODS: Retrospective observational study of all patients with CAPE treated with NIV. Patients were classified in three groups according to PaCO2 level (hypocapnic, eucapnic and hypercapnic). NIV failure was defined as the need for endotracheal intubation and/or death. RESULTS: 1138 patients were analysed, 390 (34.3%) of which had hypocapnia, 186 (16.3%) had normocapnia and 562 (49.4%) had hypercapnia. NIV failure was more frequent in hypocapnic (60 patients, 15.4%) than in eucapnic (16 pacientes, 8.6%) and hypercapnic group (562 pacientes, 10.7%), with statistical significance (p = 0.027), as well as hospital mortality, 73 (18.7%), 19(10.2%) and 83 (14.8%) respectively (p = 0.026). The predicted factors for NIV failure were the presence of do-not-intubate order, complications related to NIV, a lower left ventricular ejection fraction, higher SAPS II and SOFA score and a higher HACOR score at one hour of NIV initiation. CONCLUSIONS: Hypocapnia in patients with CAPE is associated with NIV failure and a greater in-hospital mortality.

Early radiological worsening of SARS-CoV-2 pneumonia predicts the need for ventilatory support.

OBJECTIVES: Identifying early markers of poor prognosis of coronavirus disease 2019 (COVID-19) is mandatory. Our purpose is to analyze by chest radiography if rapid worsening of COVID-19 pneumonia in the initial days has predictive value for ventilatory support (VS) need. METHODS: Ambispective observational ethically approved study in COVID-19 pneumonia inpatients, validated in a second outpatient sample. Brixia score (BS) was applied to the first and second chest radiography required for suspected COVID-19 pneumonia to determine the predictive capacity of BS worsening for VS need. Intraclass correlation coefficient (ICC) was previously analyzed among three radiologists. Sensitivity, specificity, likelihood ratios, AUC, and odds ratio were calculated using ROC curves and binary logistic regression analysis. A value of p < .05 was considered statistically significant. RESULTS: A total of 120 inpatients (55 ± 14 years, 68 men) and 112 outpatients (56 ± 13 years, 61 men) were recruited. The average ICC of the BS was between 0.812 (95% confidence interval 0.745-0.878) and 0.906 (95% confidence interval 0.844-0.940). According to the multivariate analysis, a BS worsening per day > 1.3 points within 10 days of the onset of symptoms doubles the risk for requiring VS in inpatients and 5 times in outpatients (p < .001). The findings from the second chest radiography were always better predictors of VS requirement than those from the first one. CONCLUSION: The early radiological worsening of SARS-CoV-2 pneumonia after symptoms onset is a determining factor of the final prognosis. In elderly patients with some comorbidity and pneumonia, a 48-72-h follow-up radiograph is recommended. KEY POINTS: • An early worsening on chest X-ray in patients with SARS-CoV-2 pneumonia is highly predictive of the need for ventilatory support. • This radiological worsening rate can be easily assessed by comparing the first and the second chest X-ray. • In elderly patients with some comorbidity and SARS-CoV-2 pneumonia, close early radiological follow-up is recommended.

Outcome of patients with acute heart failure secondary to acute myocardial infarction treated with noninvasive mechanical ventilation.

INTRODUCTION AND OBJECTIVES: Noninvasive ventilation (NIV) has been shown to reduce the rate of endotracheal intubation and mortality in patients with acute heart failure (AHF). However, patients with AHF secondary to acute coronary syndrome/acute myocardial infarction (ACS-AMI) have been excluded from many clinical trials. The purpose of this study was to compare the effectiveness of NIV between patients with AHF triggered by ACS-AMI and by other etiologies. METHODS: Prospective cohort study of all patients with AHF treated with NIV admitted to the intensive care unit for a period of 20 years. Patients were divided according to whether they had ACS-AMI as the cause of the AHF episode. NIV failure was defined as the need for endotracheal intubation or death. RESULTS: A total of 1009 patients were analyzed, 403 (40%) showed ACS-AMI and 606 (60%) other etiologies. NIV failure occurred in 61 (15.1%) in the ACS-AMI group and in 64 (10.6%) in the other group (P=.031), without differences in in-hospital mortality (16.6% and 14.9%, respectively; P=.478). CONCLUSIONS: The presence of ACS-AMI as the triggering cause of AHF did not influence patients with acute respiratory failure requiring noninvasive respiratory support.

Effectiveness of Non-Presential Individualized Exercise Training PrOgram(NIETO) in Lower Limb Physical Performance in Advanced COPD.

Muscle training, a component of pulmonary rehabilitation (PR), improves the physical performance of patients with chronic obstructive pulmonary disease (COPD). Despite the existing evidence, the traditional center-based PR model is applied to a small percentage of patients and presents numerous problems of accessibility, adherence, and costs. This study presents a home model of simple muscle training, non-presential, monitored by telephone and individualized, according to the severity of the COPD. In addition, to evaluate the results, simple tests associated with the physical performance of the lower limbs, previously validated in COPD, have been used, such as the four-meter walk, speed test (4MGS) and the five-repetition test sitting and standing (5STS). The objective was to evaluate whether the Individualized Non-Presential Exercise Training PrOgram (NIETO) induces improvements in the 4MGS, 5STS and quadriceps muscle strength (QMS) tests in outpatients with advanced COPD (FEV1 ≤ 50%). After one year, the QMS was significantly higher in the intervention group (IG) than in the control group (CG) (2.44 ± 4.07 vs. 0.05 ± 4.26 kg; p = 0.009). The 4MGS and 5STS tests were significantly shorter in IG than in CG (-0.39 ± 0.86 vs. 0.37 ± 0.96 s; p = 0.001) and (-1.55 ± 2.83 vs. 0.60 ± 2.06 s; p = 0.001), respectively. A home model of simple muscle training monitored by telephone such as NIETO, can improve 4MGS, 5STS, and quadriceps strength tests in outpatients with advanced COPD.

Discontinuation of disease-modifying treatments in multiple sclerosis to plan a pregnancy: A retrospective registry study.

BACKGROUND: For safety reasons multiple sclerosis (MS) treatment guidelines recommend stopping or delaying the onset of disease-modifying therapies (DMT) before a planned pregnancy, but disease stability after DMT discontinuation is not well studied. The objective of this study is to describe the course of MS in patients who interrupted DMT before a planned pregnancy. METHODS: This was a retrospective study using 2008-2016 data from a multicenter register of pregnancies in women with MS. In this paper, we present data from the subgroup of women with relapsing-remitting MS (RRMS) who interrupted DMT to try to conceive. Data from 1 and 3 years before DMT interruption, the period between DMT interruption and conception or resuming DMT, during pregnancy and one year postpartum were analyzed. Annualized relapse rates (ARR), Expanded Disability Status Scale (EDSS) scores, and magnetic resonance imaging (MRI), obstetric, and neonatal data were collected. RESULTS: Twenty-seven women interrupted DMT (19 ß-interferon, 5 glatiramer acetate, 2 natalizumab and 1 fingolimod) to try to conceive. After a mean of 10.6 months 6 women stopped trying to conceive and resumed DMT, while 21 women became pregnant after a mean of 7.0 months. In the overall cohort, in the period from when DMT was discontinued to when pregnancy was confirmed or DMT resumed, the ARR was 1.08, which was significantly higher than the ARR 1 year (0.44; p = 0.01) and 3 years (0.4; p = 0.06) before DMT discontinuation. The mean EDSS score when pregnancy was confirmed or DMT resumed was significantly higher than at DMT discontinuation (1.8 vs 1.36, p = 0.011). In the subgroup of patients who became pregnant, the ARR in the untreated period before pregnancy was 0.98, which was significantly higher than the ARR 1 year (0.38; p = 0.03) and 3 years (0.39; p = 0.0077) before DMT discontinuation. The ARR decreased to 0.51 during pregnancy and then increased to 0.76 during the first postpartum trimester (not significant). One year after delivery, the mean EDSS score (1.86) was significantly higher than at DMT cessation (1.35, p = 0.027) or pregnancy confirmation (1.45, p = 0.026). Patients who suffered relapses following DMT cessation before becoming pregnant had an 11-fold higher risk of relapse during pregnancy (relative risk [RR] = 11.1 [95%CI 1.6, 75], p = 0.002) and a 3-fold higher risk during the postpartum year (RR = 3.0 [95%CI 1.3,6.6], p = 0.007) than those who did not suffer relapses in period between DMT withdrawal and pregnancy. CONCLUSIONS: In this retrospective registry study, discontinuation of DMT (mostly immunomodulatory drugs), to try to conceive resulted in an increase in MS relapse rates and disability progression.

Is the number of rib fractures a risk factor for delayed complications? A case-control study.

AIM: To analyse factors that may predict the appearance of rib fracture complications during the first days of evolution and determine whether the number of fractures is related to these complications. METHOD: Retrospective case-control study of patients admitted with a diagnosis of rib fractures between 2010 and 2014. Two groups were established depending on the appearance or not of pleuropulmonary complications in the first 72 h, and the following were compared: age, sex, Charlson comorbidity index (CCI), number and uni- or bilateral involvement, mechanism of trauma, days of hospital stay, haemoglobin on discharge minus haemoglobin on admission, pleuropulmonary complications during admission (pneumothorax, haemothorax or pulmonary contusion) and placement of pleural drainage. RESULTS: One hundred and forty-one cases of rib fractures were admitted in the period mentioned. There were no differences in the patients' baseline characteristics (age, sex and Charlson Comorbidity Index) between the two groups. Differences were found in the number of fractures (2.98 ± 1.19 in the group without complications vs 3.55 ± 1.33 in the group with complications, p = 0.05) and in the drop in the level of haemoglobin (0.52 ± 0.91 mg/dl vs 1.22 ± 1.29 mg/dl, p = 0.01). The length of hospital stay varied considerably in each group (5.35 ± 4.05 days vs 7.86 ± 6.96 days), but without statistical significance (p = 0.11). CONCLUSIONS: The number of fractured ribs that best predicted the appearance of complications (delayed pleuropulmonary complications and greater bleeding) was 3 or more.

[Nutritional factors associated with complications in major abdominopelvic surgery]. / Factores nutricionales asociados a complicaciones en cirugía mayor abdominopélvica.

INTRODUCTION: major abdomino-pelvic surgery includes a series of procedures that carry a high percentage of postoperative complications. Our objective is to identify the factors related to post-surgical complications, classified according to Clavien-Dindo classification, with special attention to nutritional factors in patients who undergo major abdomino-pelvic surgery. MATERIAL AND METHOD: retrospective observational study between July 2012 and December 2013. A total of 255 patients undergoing major abdomino-pelvic surgery (colorectal, gastric, obesity or total cystectomy) were selected on a scheduled basis. Four types of variables were collected: sociodemographic, baseline, diagnostic and outcome variables, including perioperative complications that were classified in 5 grades according to the Clavien-Dindo scale, and for the analysis of results, two groups of patients were separated: The group with complications grade 0 and I and group 2 with complications III to V. The statistical analysis was performed using IBM SPSS version 22.0. RESULTS: patients had a mean age of 65 years. Twenty patients (7.8%) returned in the first 30 days after surgery and 8 patients (3.1%) died. 152 cases (59.6%) were classified in group 1 and 103 cases (40.4%) in group 2. When analyzing both groups, we found significant differences in the operative variables: type of surgery and laparoscopic or open approach. Regarding the physiological and nutritional parameters, we observed significant differences in the following factors: preoperative BMI, preoperative albumin, preoperative hemoglobin and day of onset of postoperative tolerance. CONCLUSION: in our study we have identified modifiable factors, such as hemoglobin and preoperative albumin, BMI and early onset of oral tolerance, related to postoperative morbidity. Preoperative nutritional status is related to postoperative complications in major abdomino-pelvic surgery.

Carcinoma de tiroides incidental versus no incidental: presentación clínica, tratamiento quirúrgico y pronóstico / Incidental versus non-incidental thyroid carcinoma: clinical presentation, surgical management and prognosis

Antecedentes y objetivo: El cáncer tiroideo puede manifestarse clínicamente por la presencia de un nódulo cervical, o constituir un hallazgo casual en el estudio histológico de la glándula extirpada con diagnóstico, a priori, benigno. El objetivo del presente estudio fue estudiar las diferencias clínicas, de manejo quirúrgico y curso evolutivo entre los tumores tiroideos incidentales y los tumores detectados clínicamente. Material y métodos: Estudio retrospectivo de pacientes intervenidos por enfermedad tiroidea, ya fuese benigna o maligna, en el período comprendido entre enero de 2000 y marzo de 2014. De 1.415 pacientes que se sometieron a algún tipo de cirugía tiroidea se identificaron un total de 264 neoplasias, de las cuales 170 fueron incidentales. Se realizó comparación entre carcinomas incidentales versus no incidentales. Además, entre los incidentales se compararon los casos cuya indicación quirúrgica fue enfermedad de Graves frente a bocio multinodular. Resultados: Los carcinomas incidentales presentaron estadios más precoces y requirieron cirugía menos agresiva. No se observaron diferencias en las complicaciones quirúrgicas entre ambos grupos, aunque tanto la mortalidad como las tasas de recidiva fueron notablemente mayores en el grupo de no incidentales (4,4% vs 0% y 13,2% vs 4,8% respectivamente). Los carcinomas desarrollados sobre enfermedad de Graves no mostraron diferencias respecto al resto de los tumores incidentales, respecto a complicaciones, mortalidad o recidiva tras la cirugía. Conclusiones: El cáncer tiroideo en estadios iniciales presenta mayor supervivencia y mejor respuesta al tratamiento quirúrgico (AU)

Background and objective: Thyroid cancer may be clinically evident as a tumor mass in the neck or as a histopathological incidental finding after thyroid surgery for an apparent benign condition. Our objective was to assess the differences in clinical signs, surgical management, and course between incidental and clinically diagnosed thyroid tumors. Methods: A retrospective study was conducted on patients operated on for benign or malignant thyroid disease from January 2000 to March 2014. Among the 1415 patients who underwent any thyroid surgery, 264 neoplasms were found, of which 170 were incidental. A comparison was made of incidental versus non-incidental carcinomas. Among incidental carcinomas, cases whose indication for surgery was Graves’ disease were compared to those with multinodular goiter. Results: Incidental carcinomas were in earlier stages and required less aggressive surgery. There were no differences in surgical complications between incidental and clinical tumors, but mortality and relapses were markedly higher in non-incidental cancers (4.4% vs 0% and 13.2% vs 4.8% respectively). Carcinomas developing on Graves’ disease showed no differences from all other incidental tumors in terms of complications, mortality, or relapse after surgery. Conclusions: Early stage thyroid cancer has better survival and prognosis after surgical treatment (AU)

Efficacy of a self-management plan in exacerbations for patients with advanced COPD.

BACKGROUND: Self-management interventions improve different outcome variables in various chronic diseases. Their role in COPD has not been clearly established. We assessed the efficacy of an intervention called the self-management program on the need for hospital care due to disease exacerbation in patients with advanced COPD. METHODS: Multicenter, randomized study in two hospitals with follow-up of 1 year. All the patients had severe or very severe COPD, and had gone to either an accident and emergency (A&E) department or had been admitted to a hospital at least once in the previous year due to exacerbation of COPD. The intervention consisted of a group education session on the main characteristics of the disease, an individual training session on inhalation techniques, at the start and during the 3rd month, and a written action plan containing instructions for physical activity and treatment for stable phases and exacerbations. We determined the combined number of COPD-related hospitalizations and emergency visits per patient per year. Secondary endpoints were number of patients with visits to A&E and the number of patients hospitalized because of exacerbations, use of antibiotics and corticosteroids, length of hospital stay, and all-cause mortality. RESULTS: After 1 year, the rate of COPD exacerbations with visits to A&E or hospitalization had decreased from 1.37 to 0.89 (P=0.04) and the number of exacerbations dropped from 52 to 42 in the group of patients who received the intervention. The numbers of patients hospitalized, at 19 (40.4%) versus 20 (52.6%) (P=0.26), and those who went to A&E, at 9 (19.1%) versus 14 (36.8%) (P=0.06), due to exacerbation of COPD were also lower in this group. Intake of antibiotics was higher in the intervention group, whereas use of glucocorticoids was slightly lower, though there were no significant differences (P=0.30). There were also no differences between groups in the length of hospital stay (P=0.154) or overall mortality (P=0.191). CONCLUSION: The implementation of a self-management program for patients with advanced COPD reduced exacerbations that required hospital care.

Variables relacionadas con la diseminación metastásica axilar en el cáncer de mama con ganglio centinela positivo. Evaluación de modelos predictivos / Factors related to metastatic axillary disease in breast cancer patients with a positive sentinel lymph node. Evaluation of predictive models

Objetivos. Evaluar las variables relacionadas con la diseminación metastásica axilar e intentar validar los diferentes modelos predictivos creados hasta la fecha. Pacientes y método. Realizamos un estudio retrospectivo a lo largo de 10 años. Fueron incluidas todas las pacientes intervenidas de cáncer de mama en nuestro hospital con ganglio centinela positivo. Se recogieron 27 variables clínico/histológicas del tumor y se realizó un análisis uni/multivariante para valorar la relación con la presencia de metástasis en ganglios axilares no centinelas. Se aplicaron los modelos predictivos a nuestra población: MSKCC, Stanford, Tenon, Meretoja unicéntrico y Meretoja multicéntrico y se calculó para cada uno de ellos el área bajo la curva de característica operativa de receptor (ROC). Resultados. Las variables significativas con la diseminación metastásica axilar fueron el IMC, la macrometástasis en el ganglio centinela, la unifocalidad y la extensión extranodal. Ningún modelo predictivo pudo ser validado, pues todos presentan una capacidad discriminativa diagnóstica baja, con áreas bajo la curva menores de 0,7. Conclusiones. Los modelos predictivos de diseminación metastásica axilar en caso de ganglio centinela positivo por sí solos no permiten discriminar aquellas pacientes con afectación metastásica axilar en el ganglio no centinela (AU)

Objectives. To evaluate factors related to metastatic axillary disease and to validate and update the predictive models created to date for metastatic axillary disease. Patients and method. In this retrospective study, we included all patients with a positive sentinel lymph node biopsy who underwent breast cancer surgery in our hospital in the last 10 years. We obtained 27 clinical/histopathological variables for each patient and univariate and multivariate statistical analyses were performed to evaluate the relationship between these variables and the presence of metastases in non-sentinel axillary nodes. We applied the main published predictive models (MSKCC, Stanford, Tenon, Meretoja single-center and multicenter models) to our population. The area under the receiver operating characteristic curve was calculated for each of the models. Results. The variables significantly related to metastatic axillary disease were body mass index, macrometastases in the sentinel lymph node, single-focus, and extranodal spread. None of the predictive models was validated because all of them had low diagnostic discrimination, with areas below the curve lower than 0.7. Conclusions. Predictive models for metastatic axillary disease in patients with a positive sentinel lymph node have low diagnostic accuracy in identifying low risk patients (AU)

Implementing evidence in an onco-haematology nursing unit: a process of change using participatory action research.

AIM: To implement evidence in a nursing unit and to gain a better understanding of the experience of change within a participatory action research. METHODS: Study design of a participatory action research type was use from the constructivist paradigm. The analytical-methodological decisions were inspired by Checkland Flexible Systems for evidence implementation in the nursing unit. The study was carried out between March and November 2007 in the isolation unit section for onco-haematological patients in a tertiary level general university hospital in Spain. Accidental sampling was carried out with the participation of six nurses. Data were collected using five group meetings and individual reflections in participants' dairies. The participant observation technique was also carried out by researchers. Data analysis was carried out by content analysis. The rigorous criteria were used: credibility, confirmability, dependence, transferability and reflexivity. RESULTS: A lack of use of evidence in clinical practice is the main problem. The factors involved were identified (training, values, beliefs, resources and professional autonomy). Their daily practice (complexity in taking decisions, variability, lack of professional autonomy and safety) was compared with an ideal situation (using evidence it will be possible to normalise practice and to work more effectively in teams by increasing safety and professional recognition). It was decided to create five working areas about several clinical topics (mucositis, pain, anxiety, satisfaction, nutritional assessment, nauseas and vomiting, pressure ulcers and catheter-related problems) and seven changes in clinical practice were agreed upon together with 11 implementation strategies. Some reflections were made about the features of the study: the changes produced; the strategies used and how to improve them; the nursing 'subculture'; attitudes towards innovation; and the commitment as participants in the study and as healthcare professionals. CONCLUSIONS: The findings throw light on the process of change in the healthcare sector. The results are useful to modify nursing practice based on evidence.

Randomized clinical trial of laparoscopic hernia repair comparing titanium-coated lightweight mesh and medium-weight composite mesh.

BACKGROUND: The use of lightweight meshes in incisional hernia repair could have beneficial effects on quality of life. This study aimed to compare a new titanium-coated lightweight mesh with a standard composite mesh after laparoscopic incisional hernia repair. METHODS: A randomized controlled single-center clinical trial was designed using the basic principle of one unit, one surgeon, one technique (midline incisional hernia with a laparoscopic approach), and two meshes: a lightweight titanium-coated mesh (group 1) and a medium-weight collagen-polyester composite mesh (group 2) used in 102 patients. The primary end points were pain and recurrence. The secondary end points were morbidity and patient outcomes (analgesic consumption, return to everyday activities). RESULTS: The postoperative complication rates were similar for the two meshes. Pain was significantly less common in group 1 than in group 2 at 1 month (P = 0.029) but was similar for the two groups at 6 months and 1 year. There was a significant difference between the two groups in the average use of analgesics: 6.1 days in group 1 versus 1.6 days in group 2 (P < 0.001). The lightweight group returned to everyday activities after 6.9 days versus 9.7 days for the composite group (P < 0.001). The rate of recurrence did not differ between the two groups at the 2-year follow-up evaluation. CONCLUSIONS: The light titanium-covered polypropylene mesh was associated with less postoperative pain in the short term, lower analgesic consumption, and a quicker return to everyday activities than the Parietex composite medium-weight mesh. The recurrence rates at 2 years showed no difference between the two groups.

Evaluation of the effectiveness of hospital discharge planning and follow-up in the primary care of patients with chronic obstructive pulmonary disease.

AIMS AND OBJECTIVES: To evaluate the effectiveness of protocolised intervention for hospital discharge and follow-up in the primary care of patients with chronic obstructive pulmonary disease (COPD). BACKGROUND: Chronic obstructive pulmonary disease is one of the main causes of morbidity and mortality internationally. DESIGN: A quasi-experimental design was adopted, with a control group and it was pseudorandomised by services. METHODS: Patients with COPD admitted to two tertiary-level public hospitals in Spain were recruited (2007-2008). The outcome variables included: readmission rate, patient satisfaction (LOPSS12), quality of life (St. George's Respiratory Questionnaire) and level of knowledge about COPD. 48 hours after admission, both groups were evaluated by specialist coordinating nurses. At the hospital, a coordinating nurse visited each patient in the experimental group every 24 hours to identify the main caregiver, provide information about the disease, explain treatment, identify care problems and needs and facilitate communication between professionals. 24 hours after discharge, the coordinating nurses informed the primary care nurses about patient discharge. The two nurses made the first home visit together. There were follow-up phone calls at 2, 6, 12 and 24 weeks after discharge. A total of 143 patients were recruited (Intervention group=56; Control group=87). RESULTS: The results showed a significant improvement in the evolution of quality of life, at 12 and 24 weeks after discharge; the level of knowledge about COPD revealed significant differences between the groups. There were no differences according to satisfaction or readmission rate. Multivariate analysis (non-conditional logistic regression) showed the intervention to be ineffective in reducing the readmission rate. CONCLUSIONS: The planning of discharge for patients with COPD is effective in terms of improving the patients' quality of life and level of knowledge about the disease. RELEVANCE TO CLINICAL PRACTICE: The characteristics of patients with COPD make it necessary to include them in hospital discharge planning programmes.

Reduction in inappropriate hospital use based on analysis of the causes.

BACKGROUND: To reduce inappropriate admissions and stays with the application of an improvement cycle in patients admitted to a University Hospital. The secondary objective is to analyze the hospital cost saved by reducing inadequacy after the implementation of measures proposed by the group for improvement. METHODS: Pre- and post-analysis of a sample of clinical histories studied retrospectively, in which the Appropriateness Evaluation Protocol (AEP) was applied to a representative hospital sample of 1350 clinical histories in two phases. In the first phase the AEP was applied retrospectively to 725 admissions and 1350 stays. The factors associated with inappropriateness were analysed together with the causes, and specific measures were implemented in a bid to reduce inappropriateness. In the second phase the AEP was reapplied to a similar group of clinical histories and the results of the two groups were compared. The cost of inappropriate stays was calculated by cost accounting. SETTING: General University Hospital with 426 beds serving a population of 320,000 inhabitants in the centre of Murcia, a city in south-eastern Spain. RESULTS: Inappropriate admissions were reduced significantly: 7.4% in the control group and 3.2% in the intervention group. Likewise, inappropriate stays decreased significantly from 24.6% to 10.4%. The cost of inappropriateness in the study sample fell from 147,044 euros to 66,642 euros. The causes of inappropriateness for which corrective measures were adopted were those that showed the most significant decrease. CONCLUSIONS: It is possible to reduce inadequacy by applying measures based on prior analysis of the situation in each hospital.

Is intravenous iron useful for reducing transfusions in surgically treated colorectal cancer patients?

BACKGROUND: The goal of the present study was to determine whether the intravenous administration of iron in the postoperative period of colon cancer surgical patients suffices to reduce the number of transfusions necessary. METHOD: The study was designed as a retrospective observational study conducted over a three-year period. A paired case-control design was used to analyze the effect of postoperative iron on patients' blood transfusion needs. Two groups were established (the case group, which received postoperative iron and the control group, which did not) and matched for age (± 3 years), gender, type of operation, tumor stage, and surgical approach. Of 342 patients who underwent operation, 104 paired patients were obtained for inclusion in this study (52 in each group). A second analysis was made to assess the effect of intravenous iron on the evolution of hemoglobin between the first postoperative day and hospital discharge in the subgroup of patients with reduction in hemoglobin, in subjects without preoperative or postoperative transfusions. Finally, a total of 71 patients were paired in two groups: 37 and 31 patients in case and control, respectively. RESULTS: The mean hemoglobin concentration at discharge for the case group was 10 ± 1.1 g/dl, vs. 10.6 ± 1.2 in the controls (P = 0.012). The number of transfusions in the case group was 3 ± 1.6, vs. 3.3 ± 3 in the control group (P = 0.682). Thus, 28.8 % of the patients in the case group received transfusions, versus 30.8 % of those in the control group (P = 0.830). In the second analysis, the decrease in hemoglobin concentration was 0.88 g/dl and 0.82 g/dl in case and control, respectively. CONCLUSIONS: Intravenous iron does not appear to reduce the blood transfusion requirements in the postoperative period of colorectal surgery patients with anemia. We consider that further studies are needed to more clearly define the usefulness of intravenous iron in reducing the transfusion needs in such patients.
