Decreased mortality among patients with catheter-related bloodstream infections at Catalan hospitals (2010-2019).

BACKGROUND: The incidence of catheter-related bloodstream infections (CRBSIs) has fallen over the last decade, especially in intensive care units (ICUs). AIM: To assess the existence of concomitant trends in outcomes and to analyse the current risk factors for mortality. METHODS: A multicentre retrospective cohort study was conducted at 24 Catalan hospitals participating in the Surveillance of healthcare-associated infections in Catalonia (VINCat). All hospital-acquired CRBSI episodes diagnosed from January 2010 to December 2019 were included. A common protocol including epidemiological, clinical, and microbiological data was prospectively completed. Mortality at 30 days after bacteraemia onset was analysed using the Cox regression model. FINDINGS: Over the study period, 4795 episodes of CRBSI were diagnosed. Among them, 75% were acquired in conventional wards and central venous catheters were the most frequently involved (61%). The 30-day mortality rate was 13.8%, presenting a significant downward trend over the study period: from 17.9% in 2010 to 10.6% in 2019 (hazard ratio (HR): 0.95; 95% confidence interval (CI): 0.92-0.98). The multivariate analysis identified age (HR: 1.03; 95% CI: 1.02-1.04), femoral catheter (1.78; 1.33-2.38), medical ward acquisition (2.07; 1.62-2.65), ICU acquisition (3.45; 2.7-4.41), S. aureus (1.59; 1.27-1.99) and Candida sp. (2.19; 1.64-2.94) as risk factors for mortality, whereas the mortality rate associated with episodes originating in peripheral catheters was significantly lower (0.69; 0.54-0.88). CONCLUSION: Mortality associated with CRBSI has fallen in recent years but remains high. Intervention programmes should focus especially on ICUs and medical wards, where incidence and mortality rates are highest.

Economic burden of recurrent Clostridioides difficile infection in adults admitted to Spanish hospitals. A multicentre retrospective observational study.

OBJECTIVE: Clostridioides difficile infection (CDI) is associated with increased hospital stays and mortality and a high likelihood of rehospitalization, leading to increased health resource use and costs. The objective was to estimate the economic burden of recurrent CDI (rCDI). METHODS: Observational, retrospective study carried out in six hospitals. Adults aged ≥18 years with ≥1 confirmed diagnosis (primary or secondary) of rCDI between January 2010 and May 2018 were included. rCDI-related resource use included days of hospital stay (emergency room, ward, isolation and ICU), tests and treatments. For patients with primary diagnosis of rCDI, the complete hospital stay was attributed to rCDI. When diagnosis of rCDI was secondary, hospital stay attributed to rCDI was estimated using 1:1 propensity score matching as the difference in hospital stay compared to controls. Controls were hospitalizations without CDI recorded in the Spanish National Hospital Discharge Database. The cost was calculated by multiplying the natural resource units by the unit cost. Costs (euros) were updated to 2019. RESULTS: We included 282 rCDI episodes (188 as primary diagnosis): 66.31% of patients were aged ≥65 years and 57.80% were female. The mean hospital stay (SD) was 17.18 (23.27) days: 86.17% of rCDI episodes were isolated for a mean (SD) of 10.30 (9.97) days. The total mean cost (95%-CI) per episode was €10,877 (9,499-12,777), of which the hospital stay accounted for 92.56. CONCLUSIONS: There is high cost and resource use associated with rCDI, highlighting the importance of preventing rCDI to the Spanish National Health System.

Impact of a training program on the surveillance of Clostridioides difficile infection.

A high degree of vigilance and appropriate diagnostic methods are required to detect Clostridioides difficile infection (CDI). We studied the effectiveness of a multimodal training program for improving CDI surveillance and prevention. Between 2011 and 2016, this program was made available to healthcare staff of acute care hospitals in Catalonia. The program included an online course, two face-to-face workshops and dissemination of recommendations on prevention and diagnosis. Adherence to the recommendations was evaluated through surveys administered to the infection control teams at the 38 participating hospitals. The incidence of CDI increased from 2.20 cases/10 000 patient-days in 2011 to 3.41 in 2016 (P < 0.001). The number of hospitals that applied an optimal diagnostic algorithm rose from 32.0% to 71.1% (P = 0.002). Hospitals that applied an optimal diagnostic algorithm reported a higher overall incidence of CDI (3.62 vs. 1.92, P < 0.001), and hospitals that were more active in searching for cases reported higher rates of hospital-acquired CDI (1.76 vs. 0.84, P < 0.001). The results suggest that the application of a multimodal training strategy was associated with a significant rise in the reporting of CDI, as well as with an increase in the application of the optimal diagnostic algorithm.

Experiencia en manejo anestésico para cirugía no cardiaca en pacientes con asistencias ventriculares / Experience in anaesthetic management of non-cardiac surgery in patients with ventricular assist devices

La insuficiencia cardiaca constituye un cuadro sindrómico de elevada incidencia en la medicina actual. Cuando los síntomas de la insuficiencia cardiaca progresan y se convierten en refractarios, la indicación de trasplante cardiaco es la mejor opción terapéutica. Sin embargo, debido a la escasez de donantes y a las largas listas de espera, muchos de estos pacientes necesitan la implantación de dispositivos de asistencia ventricular como puente a este trasplante, o en algunos casos, cuando el trasplante no es una opción, como terapia definitiva. En este artículo se presenta una serie de 4 casos clínicos en pacientes portadores de dispositivos de asistencia ventricular que precisaron intervención quirúrgica. Tres de ellos estaban asistidos con asistencias de larga duración: 2 EXCOR (pulsátiles y paracorpórea) y un HEARTWARE (no pulsátil e intracorpórea) y el último con una asistencia de corta duración; CentriMag Levitronix biventricular. No existe bibliografía significativa sobre las implicaciones perioperatorias de estos pacientes cuando son sometidos a cirugía urgente o programada. La experiencia en nuestro centro nos lleva a plantear la necesidad de conocer una serie de aspectos: funcionamiento de cada dispositivo, recalcando la correcta colocación de las cánulas durante la cirugía; el manejo apropiado de la medicación, recalcando la importancia de las terapias anticoagulantes y antiagregantes; los cambios fisiopatológicos a nivel cardiopulmonar debidos a la implantación de estos dispositivos; y la importancia de la administración de una correcta antibioterapia. Ante la complejidad que presentan estos casos, la escasa experiencia en este campo y los pocos casos que existen de estas situaciones se recomienda la creación de protocolos para garantizar un manejo correcto de estos

Heart failure (HF) is a syndromic condition with a high incidence in current medicine. When the symptoms of HF progress, and become refractory, cardiac transplant is the best therapeutic option. However, due to the shortage of donors and the long waiting lists, many of those patients are candidates for implantation of ventricular assist devices as a bridge to the cardiac transplant, or when this is not an option, as a definitive therapy. A series of four clinical cases of patients with ventricular assist devices that required surgical intervention, is presented. Three of them were assisted with long-term care: two EXCOR (pulsatile and para-corporeal) and one HEARTWARE (non-pulsatile and intra-corporeal), and the last one with short-term assistance; CentriMag biventricular Levitronix. There is no significant literature on the peri-operative implications of these patients when they undergo urgent or scheduled surgery. The experience in our centre leads us to raise the need to determine a series of aspects: operation of each device, emphasising the correct placement of the cannulas during the surgery; the proper management of any medication, emphasising the importance of anticoagulant and anti-platelet therapies; the Pathophysiological changes at cardiopulmonary level due to the implantation of these devices; and the importance of the administration of a correct antibiotic therapy. Given the complexity of these cases, the limited experience in this field, and the few cases that exist in these situations, it is recommended to create protocols to ensure their proper management

Impact of participation in a surgical site infection surveillance network: results from a large international cohort study.

BACKGROUND: Surveillance of surgical site infections (SSIs) is a core component of effective infection control practices, though its impact has not been quantified on a large scale. AIM: To determine the time-trend of SSI rates in surveillance networks. METHODS: SSI surveillance networks provided procedure-specific data on numbers of SSIs and operations, stratified by hospitals' year of participation in the surveillance, to capture length of participation as an exposure. Pooled and procedure-specific random-effects Poisson regression was performed to obtain yearly rate ratios (RRs) with 95% confidence intervals (CIs), and including surveillance network as random intercept. FINDINGS: Of 36 invited networks, 17 networks from 15 high-income countries across Asia, Australia and Europe participated in the study. Aggregated data on 17 surgical procedures (cardiovascular, digestive, gynaecological-obstetrical, neurosurgical, and orthopaedic) were collected, resulting in data concerning 5,831,737 operations and 113,166 SSIs. There was a significant decrease in overall SSI rates over surveillance time, resulting in a 35% reduction at the ninth (final) included year of surveillance (RR: 0.65; 95% CI: 0.63-0.67). There were large variations across procedure-specific trends, but strong consistent decreases were observed for colorectal surgery, herniorrhaphy, caesarean section, hip prosthesis, and knee prosthesis. CONCLUSION: In this large, international cohort study, pooled SSI rates were associated with a stable and sustainable decrease after joining an SSI surveillance network; a causal relationship is possible, although unproven. There was heterogeneity in procedure-specific trends. These findings support the pivotal role of surveillance in reducing infection rates and call for widespread implementation of hospital-based SSI surveillance in high-income countries.

Preoperative oral antibiotic prophylaxis reduces Pseudomonas aeruginosa surgical site infections after elective colorectal surgery: a multicenter prospective cohort study.

BACKGROUND: Healthcare-associated infections caused by Pseudomonas aeruginosa are associated with poor outcomes. However, the role of P. aeruginosa in surgical site infections after colorectal surgery has not been evaluated. The aim of this study was to determine the predictive factors and outcomes of surgical site infections caused by P. aeruginosa after colorectal surgery, with special emphasis on the role of preoperative oral antibiotic prophylaxis. METHODS: We conducted an observational, multicenter, prospective cohort study of all patients undergoing elective colorectal surgery at 10 Spanish hospitals (2011-2014). A logistic regression model was used to identify predictive factors for P. aeruginosa surgical site infections. RESULTS: Out of 3701 patients, 669 (18.1%) developed surgical site infections, and 62 (9.3%) of these were due to P. aeruginosa. The following factors were found to differentiate between P. aeruginosa surgical site infections and those caused by other microorganisms: American Society of Anesthesiologists' score III-IV (67.7% vs 45.5%, p = 0.001, odds ratio (OR) 2.5, 95% confidence interval (95% CI) 1.44-4.39), National Nosocomial Infections Surveillance risk index 1-2 (74.2% vs 44.2%, p < 0.001, OR 3.6, 95% CI 2.01-6.56), duration of surgery ≥75thpercentile (61.3% vs 41.4%, p = 0.003, OR 2.2, 95% CI 1.31-3.83) and oral antibiotic prophylaxis (17.7% vs 33.6%, p = 0.01, OR 0.4, 95% CI 0.21-0.83). Patients with P. aeruginosa surgical site infections were administered antibiotic treatment for a longer duration (median 17 days [interquartile range (IQR) 10-24] vs 13d [IQR 8-20], p = 0.015, OR 1.1, 95% CI 1.00-1.12), had a higher treatment failure rate (30.6% vs 20.8%, p = 0.07, OR 1.7, 95% CI 0.96-2.99), and longer hospitalization (median 22 days [IQR 15-42] vs 19d [IQR 12-28], p = 0.02, OR 1.1, 95% CI 1.00-1.17) than those with surgical site infections due to other microorganisms. Independent predictive factors associated with P. aeruginosa surgical site infections were the National Nosocomial Infections Surveillance risk index 1-2 (OR 2.3, 95% CI 1.03-5.40) and the use of oral antibiotic prophylaxis (OR 0.4, 95% CI 0.23-0.90). CONCLUSIONS: We observed that surgical site infections due to P. aeruginosa are associated with a higher National Nosocomial Infections Surveillance risk index, poor outcomes, and lack of preoperative oral antibiotic prophylaxis. These findings can aid in establishing specific preventive measures and appropriate empirical antibiotic treatment.

Multistate modelling to estimate excess length of stay and risk of death associated with organ/space infection after elective colorectal surgery.

BACKGROUND: Accounting for time-dependency and competing events are strongly recommended to estimate excess length of stay (LOS) and risk of death associated with healthcare-associated infections. AIM: To assess the effect of organ/space (OS) surgical site infection (SSI) on excess LOS and in-hospital mortality in patients undergoing elective colorectal surgery (ECS). METHODS: A multicentre prospective adult cohort undergoing ECS, January 2012 to December 2014, at 10 Spanish hospitals was used. SSI was considered the time-varying exposure and defined as incisional (superficial and deep) or OS. Discharge alive and death were the study endpoints. The mean excess LOS was estimated using a multistate model which provided a weighted average based on the states patients passed through. Multivariate Cox regression models were used to assess the effect of OS-SSI on risk of discharge alive or in-hospital mortality. FINDINGS: Of 2778 patients, 343 (12.3%) developed SSI: 194 (7%) OS-SSI and 149 (5.3%) incisional SSI. Compared to incisional SSI or no infection, OS-SSI prolonged LOS by 4.2 days (95% confidence interval (CI): 4.1-4.3) and 9 days (8.9-9.1), respectively, reduced the risk of discharge alive (adjusted hazard ratio (aHR): 0.36 (95% CI: 0.28-0.47) and aHR: 0.17 (0.14-0.21), respectively), and increased the risk of in-hospital mortality (aHR: 8.02 (1.03-62.9) and aHR: 10.7 (3.7-30.9), respectively). CONCLUSION: OS-SSI substantially extended LOS and increased risk of death in patients undergoing ECS. These results reinforce OS-SSI as the SSI with the highest health burden in ECS.

Predictive factors for early- and late-onset surgical site infections in patients undergoing elective colorectal surgery. A multicentre, prospective, cohort study.

BACKGROUND: Surgical site infections (SSIs) are the leading cause of healthcare-associated infections in acute care hospitals in Europe. However, the risk factors for the development of early-onset (EO) and late-onset (LO) SSI have not been elucidated. AIM: This study investigated the predictive factors for EO-SSI and LO-SSI in a large cohort of patients undergoing colorectal surgery. METHODS: We prospectively followed-up adult patients undergoing elective colorectal surgery in 10 hospitals (2011-2014). Patients were divided into three groups: EO-SSI, LO-SSI, or no infection (no-SSI). The cut-off defining EO-SSI and LO-SSI was seven days (median time to SSI development). Different predictive factors for EO-SSI and LO-SSI were analysed, comparing each group with the no-SSI patients. FINDINGS: Of 3701 patients, 320 (8.6%) and 349 (9.4%) developed EO-SSI and LO-SSI, respectively. The rest had no-SSI. Patients with EO-SSI were mostly males, had colon surgery and developed organ-space SSI whereas LO-SSI patients frequently received chemotherapy or radiotherapy and had incisional SSI. Male sex (odds ratio (OR): 1.92; P < 0.001), American Society of Anesthesiologists' physical status >2 (OR: 1.51; P = 0.01), administration of mechanical bowel preparation (OR: 0.7; P = 0.03) and stoma creation (OR: 1.95; P < 0.001) predicted EO-SSI whereas rectal surgery (OR: 1.43; P = 0.03), prolonged surgery (OR: 1.4; P = 0.03) and previous chemotherapy (OR: 1.8; P = 0.03) predicted LO-SSI. CONCLUSION: We found distinctive predictive factors for the development of SSI before and after seven days following elective colorectal surgery. These factors could help establish specific preventive measures in each group.

Post-discharge surgical site infections after uncomplicated elective colorectal surgery: impact and risk factors. The experience of the VINCat Program.

BACKGROUND: Surgical site infection (SSI) after colorectal procedures represents a measurable quality indicator of a healthcare system. There is an increasing interest in comparing SSI rates between different hospitals and countries: however, the variability of the data regarding the incidence of SSI makes this comparison difficult. For the purposes of evaluation, data collection must be standardized and must include reliable post-discharge surveillance (PDS). AIM: To determine impact and risk factors for PDS SSI after elective colorectal surgery. METHODS: VINCat is a nosocomial infection surveillance programme in Catalonia, Spain. Between 2007 and 2011, 52 hospitals joined the programme. Hospitals performed active, prospective, standardized surveillance of elective colorectal resection. PDS was implemented by a multimodal approach and was mandatory within the first 30 days after surgery. FINDINGS: During the study period, 13,661 elective colorectal procedures were included. SSI was diagnosed in 2826 (20.7%) patients, of whom 22.5% during PDS; of these, 52% required readmission. Patients with PDS SSI were younger (odds ratio: 1.57; 95% confidence interval: 1.29-1.91), predominantly female (1.40; 1.16-1.69), had more frequently undergone endoscopic procedures (1.56; 1.30-1.88) and had more incisional SSI (1.88; 1.54-2.28) than patients with in-hospital SSI. CONCLUSION: SSI rates in elective colorectal procedures at VINCat hospitals were inside the higher range of those reported by other national programmes. PDS SSI increased the overall rate of SSI, had a significant clinical impact, and accounted for almost a quarter of SSI. Younger age and laparoscopic procedures were the most relevant risk factors. Standardized multimodal PDS should be implemented for hospitals performing surveillance of colorectal surgery.

Impact of a multimodal intervention to reduce bloodstream infections related to vascular catheters in non-ICU wards: a multicentre study.

To determine the impact of a multimodal intervention designed to reduce the incidence of catheter-related bloodstream infections (CRBSIs) outside the ICU, we conducted a prospective, quasi-experimental, before-after intervention study in 11 hospitals participating in the VINCat programme in Catalonia, Spain. The intervention consists of: (i) an evidence-based bundle of practices relating to catheter insertion and maintenance; (ii) a training programme for healthcare workers; (iii) four point-prevalence surveys to track the status of the catheters; and (iv) feedback reports to the staff involved. The study included both central (CVC) and peripheral venous catheters (PVCs). Rates of CRBSI per 1000 patient-days were prospectively measured in 2009 (pre-intervention period) and 2010 (post-intervention period). The analysis included 1 191 843 patient-days in 2009 and 1 173 672 patient-days in 2010. The overall incidence of CRBSI decreased from 0.19 to 0.15 (p 0.04) and the incidence of CRBSI associated with a CVC decreased from 0.14 to 0.10 (p 0.004) after the intervention. The incidence in PVCs remained unchanged. There was a statistically significant improvement in the adequate maintenance of both CVCs and PVCs. Among the CRBSIs originating in PVCs, 61.8% appeared more than 72 h every insertion. There was a lower infection rate in the hospitals with a higher adherence to the recommendation to replace PVCs after 72 h. Our findings suggest that the implementation of intervention programmes similar to ours could have a major impact on patient safety by reducing the incidence of CRBSIs, and that routine replacement of PVCs might additionally prevent a significant number of bloodstream infections.

An expandable prosthesis with dual cage-and-plate function in a single device for vertebral body replacement: the clinical experience on 14 consecutive cases with vertebral tumors.

AIM: The aim of this paper was to test the hypothesis that an expandable prosthesis with dual cage-and-plate function can provide immediate and durable spine stabilization after corpectomy. METHODS: We designed an expandable vertebral body prosthesis with dual cage-and-plate function in a single device (JR-prosthesis). Anatomical studies were performed to design a titanium-made prosthesis. Cadaver assays were done with a stainless steal device to test fixation and adequacy to the human spine anatomy. Then, 14 patients with vertebral tumors (8 metastatic) underwent corpectomy and vertebral body replacement with the JR-prosthesis. RESULTS: All patients had neurological deficit, severe pain and spine instability (mean follow-up: 25.4 months). Mean pain score before surgery in a visual analog scale improved from 7.6 to 3.0 points after operation (P=0.002). All patients achieved at least one grade of improvement in the Frankel score (P=0.003), excepting the 3 patients with Frankel grade A presurgery. Two patients with renal cell carcinoma died during the following 4 days after surgery (renal failure and massive bleeding), the rest attained a painless and stable spine immediately and maintained for long periods. No significant infections or implant failures were registered. A non-fatal case of inferior vena cava surgical injury was observed (repaired during surgery without further complications). CONCLUSION: The JR-prosthesis stabilizes the spine immediately after surgery and for the rest of the patients' life. To our knowledge, this is the first report on the clinical experience of any expandable vertebral body prosthesis with dual cage-and-plate function in a single device. These observations await confirmation in different scenarios.

Community-acquired methicillin-resistant Staphylococcus aureus infections: an emerging threat in Spain.

Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) has not been recognised previously as a cause of MRSA infections in Spain. Nineteen patients carrying Panton-Valentine leukocidin (PVL)-positive MRSA were identified in a Barcelona hospital, of whom 15 were immigrants, mostly from South America. Twelve developed skin and soft-tissue infections. The associated isolates carried the PVL gene and staphylococcal chromosomal cassette (SCC)mecIV. A dominant clone belonging to sequence type (ST)8 and related to the USA300 clone was identified by pulsed-field gel electrophoresis. This clone is emerging in Spain, primarily among immigrants from South America, but dissemination to the native Spanish population could increase.

Bloodstream infection related to catheter connections: a prospective trial of two connection systems.

Bloodstream infections (BSIs) related to central venous catheters (CVCs) and arterial catheters (ACs) are an increasing problem in the management of critically ill patients. Our objective was to assess the efficacy of a needle-free valve connection system (SmartSite), Alaris Medical Systems, San Diego, CA, USA) in the prevention of catheter-related bloodstream infection (CR-BSI). Patients admitted to an intensive care unit were prospectively assigned to have a CVC and AC connected with either a needle-free valve connection system (NFVCS) or a three-way stopcock connection (3WSC). The characteristics of the patients were similar in the two groups. Before manipulation, the NFVCS was disinfected with chlorhexidine digluconate 0.5% alcoholic solution. The 3WSC was not disinfected between use but it was covered with a protection cap. A total of 799 patients requiring the insertion of a multilumen CVC or AC for >48h from 1 April 2002 to 31 December 2003 were included. CR-BSI rates were 4.61 per 1000 days of catheter use in the disinfected NFVCS group and 4.11 per 1000 days of catheter use in the 3WSC group (P=0.59). When CVC-BSIs and AC-BSIs were analysed separately, the rate of CVC-BSI was 4.26 per 1000 days of catheter use in the NFVCS group, compared with 5.27 in the 3WSC group (P=0.4). The incidence rate of AC-BSI was 5.00 per 1000 days of catheter use in the NFVCS group, compared with 2.83 in the 3WSC group (P=0.08). The use of NFVCS does not reduce the incidence of catheter-related bacteraemia. The arterial catheter (AC) is a significant source of infection in critically ill patients.

[Standard precautions: are these known? Are they applied?]. / Precauciones Estándar. Se conocen? Se aplican?

A study carried out among postgraduate nurses detected a high degree of confusion regarding standard precautions. This led to the formation of a multidisciplinary group from various sections of the health system to investigate this topic in greater detail. Our study observed a high degree of conceptual confusion and a lack of knowledge about standard precautions and the new recommendations regarding decontamination and hand washing in diverse health collectives. It is worrisome to detect at risk habits in relation to self-protective measures among one-third of those surveyed. Knowledge of standard precautions should be integrated with greater efficiency in the medical study programs as well as in continuing professional development programs for health professionals.

Transitory cognitive impairment in epileptic children during a CPT task.

EEGs and behavioral responses were studied in two sex matched groups of 58 epileptic and 20 healthy children between 8 and 12 years of age, during the execution of a go-no go CPT (X; A-X) task to determine transitory cognitive impairment (TCI) incidence. Paroxysmal discharges were found on 87.9% and 5% of the EEGs in the epileptic and control groups respectively, with no differences related to sex. The predominant EEG findings with respect to paroxysmal discharges were the association of two or more types of paroxysms with frequency higher than 5/minute, an average duration less than 0.5 second and topographical distribution over temporal-parietal-occipital areas without significant interhemispheric differences. TCI was detected in 36.2% of epileptic children. The epileptic group showed significantly higher numbers of behavioral errors and longer reaction times (RTs) in relation to the control group. Analyzing RTs on the two blocks of the task, linear discriminant analysis showed an acceptable classification of TCI incidence between groups.

[Effect of immunotherapy with allergens in asthmatic children with integral treatment]. / Efecto de la inmunoterapia con alergenos en niños asmáticos con tratamiento integral.

OBJECTIVE: To analyze the effect of the immunotherapy with allergens (ITA) in asthmatic pediatric patients with integral treatment. MATERIAL AND METHODS: We included children with allergic rhinitis and asthma to treatment in the Clinic of Asthma and Allergy. We made a monthly evaluation of symptoms and annual of laboratory tests. RESULTS: The results are described in averages, G1 followed by G2. They were 16 (12 M/4 F) and 17 (11 M/F) patients with ages of 6.1 +/- 2.8 and 6.2 +/- 2 years. They presented 1.2 +/- 0.5 and 1.3 +/- 0.5 crisis per month and also 4.9 +/- 3.4 and 4.8 +/- 3 hospitalizations per year. In all the treatment began with CGIDS in spray and in 8 and 7 BDP was also used. The use of b-agonists at home was bigger in G1: 3 +/- 2.1 vs 0.6 +/- 0.7 (p = 0.0004). Acute treatment in more occasions was granted in G1: 21 vs 2 (p < 0.0001). It was bigger the number of applications of CGIDS in G1: 30.1 +/- 5.3 vs 15.4 +/- 2.7 (p < 0.0001) and of immunotherapy with allergens 8.1 +/- 9.6 vs 5.1 +/- 6.4 (p = 0.1). CONCLUSIONS: The asthmatic pediatric patients on integral treatment present a bigger and quicker improvement of their rhinitic and asthmatic symptoms when they are also treated with specific IT, even from the beginning of the treatment, they also improve their general immunity and they present reduction of allergic markers. They also use less medications, they present less acute exacerbation's and less hospitalizations.
