Poisoning among the elderly. / Intoxicaciones en la tercera edad.

OBJECTIVES: Poisonings continue to be an important public health problem. Herein, we analyzed the epidemiology of poisonings in elderly individuals. METHODS: Retrospective cohort study conducted between 2011 and 2019 in a university hospital. We analyzed demographic variables, type of poison involved, suicidal or accidental nature of the poisoning, and the probability of admission, or death to the hospital. RESULTS: A total of 880 (6.1%) of the 14,300 poisonings treated in the same period occurred in people over 65 years of age. The most numerous group were individuals between 65-69 years-old (39%), followed by the group of 70-75 years-old (20%), being men 57%. In 88% of the cases a single poison participated, being by frequency alcohol (51.6%), drugs (29.5%), and household or industrial products (12.8%). Alcohol intoxication predominated in men up to 75 years of age, and above this age drug or suicidal intoxication predominated, mainly in women. A total of 145 (16%) subjects were hospitalized, the drugs most frequently implicated being digoxin and benzodiazepines. The probability of hospital admission was associated with intoxication by metformin, digoxin, lithium or with the age of the patient (OR per year = 1.03; 95% CI: 1.0-1.06). A total of 19 patients died (2.16%), mainly due to suicidal caustic ingestion (OR = 5.7: 95% CI: 1.4-23.6) or by drugs, directly related to metformin (OR = 10.1; 95% CI: 2.4-42.4). CONCLUSIONS: The prevalence of poisoning in the elderly is not negligible, and physicians should have a high index of suspicion in a complex situation.

Long-Term Mortality After Pneumonia in Cardiac Surgery Patients: A Propensity-Matched Analysis.

BACKGROUND: The role that intensive care unit (ICU)-acquired pneumonia plays in the long-term outcomes of cardiac surgery patients is not well known. This study examined the association of pneumonia with in-hospital mortality and long-term mortality after adult cardiac surgery. METHODS: A total of 2750 patients admitted to our ICU after cardiac surgery from January 2003 to December 2009 are the basis for this observational study. Patients who developed ICU-acquired pneumonia were matched with patients without it in a 1:2 ratio. The matching criteria were age, urgent or scheduled surgery, surgical procedure, and the propensity score for pneumonia. Multiple regression analysis was used to find predictors of hospital mortality. The relationship between pneumonia and long-term survival was analyzed with Kaplan-Meier survival estimates and a risk-adjusted Cox proportional regression model for patients discharged alive from hospital. RESULTS: Pneumonia was diagnosed in 32 (1.2%) patients and there were 19 cases per 1000 days of mechanical ventilation. Patients with pneumonia had a significantly higher hospital mortality rate (28% vs 6.2%, P = .003) and a higher mortality at the end of follow-up (53% vs 19%, P < .0001) than those without it. Regression analysis showed that pneumonia was a strong predictor of hospital mortality. Five-year survival was as follows: pneumonia, 62%; control, 81%; and cohort patients, 91%. The Cox model showed that, after adjusting for confounding factors, patients with pneumonia (hazard ratio = 3.96, 95% confidence interval [CI]: 1.41-11.14) had poorer long-term survival. CONCLUSION: Pneumonia remains a serious complication in patients operated for cardiac surgery and is associated with increased hospital mortality and reduced long-term survival.

Patient safety certification in a Department of Intensive Care Medicine: our experience with standard UNE 179003:2013.

Systematic and structured methods must be used to ensure that healthcare risks are effectively managed. Spanish standard UNE 179003:2013 provides healthcare organizations with a framework and a systematic protocol for managing patient safety from a clinical and organizational perspective. Furthermore, it is useful in securing an efficient balance among health risk, health outcomes and costs. The UNE 179003:2013 certifies that a clinical service complies with rules and operating procedures aimed at reducing the incidence of adverse events. It also requires mandatory continuous improvement, given that the standard entails frequent monitoring of the risk management system through periodic audits. The aims of this paper are to describe the UNE 179003:2013 certification process in an Intensive Care Unit, propose a risk management program for critical patients, and offer some recommendations regarding its implementation.

[Red cell transfusion and long-term survival in non-complicated heart surgery]. / Transfusión de hematíes y supervivencia a largo plazo en la cirugía cardíaca no complicada.

OBJECTIVE: A study was made to explore the possible association between the perioperative transfusion of 1 - 2 red blood cell units and in-hospital morbidity, 30-day mortality, and long-term survival in patients undergoing heart surgery. DESIGN: A prospective observational study was carried out. SETTING: The ICU of a university hospital. PATIENTS: All patients over 17 years of age that underwent heart surgery and were admitted to the ICU between November 2002 and December 2009 were included. Those patients who did not (n=703) and those who did (n=959) receive the perioperative transfusion of 1 - 2 red blood cell units were assessed. STUDY ENDPOINTS: The endpoints were the effect of transfusion on both hospital morbidity and on 30-day mortality. In addition, all patients discharged alive from hospital until 31 December 2011 were subjected to follow-up. The association between transfusion and survival was assessed by means of the Kaplan-Meier method. Cox proportional hazards models were used to assess factors associated with long-term survival. RESULTS: The frequency of both cardiac and non-cardiac perioperative complications was higher in patients receiving transfusion. The 30-day mortality rate was higher in those who received transfusion (1% vs 0.1%, P=.02). Preoperative anemia was associated with a more intensive use of transfusion. Red blood cell transfusion was not found to be a risk factor for long-term mortality (hazar ratio=1.4, 95%CI 0.9-2.1). CONCLUSIONS: The perioperative transfusion of 1 - 2 red blood cell units in patients undergoing heart surgery increases both hospital morbidity and the 30-day mortality rate, but does not increase long-term mortality.

Occupational exposure to endocrine-disrupting chemicals and other parental risk factors in hypospadias and cryptorchidism development: a case-control study.

AIM OF THE STUDY: Endocrine-disrupting chemicals (EDCs) are exogenous agents that are capable of altering the endocrine system functions, including the regulation of developmental processes. The aim of this study was to investigate the association between EDC exposure and other parental factors in the etiology of hypospadias and cryptorchidism. METHODS: A case-control study was conducted. Cases (n = 210) were infants aged between 6 months and 14 years diagnosed with hypospadias or cryptorchidism who attended the authors' hospital over a period of 18 months, and controls (n = 210) were infants within the same range of age and without any urological disorders who attended the outpatient clinic of the same hospital during the same time period. Their selection was independent of exposures. Data on parental occupational exposure to EDCs and other sociodemographic variables were collected through face-to-face interviews and systematically for both cases and controls. Crude and adjusted odds ratios (ORs) were estimated to control for confounding with their 95% confidence interval (CI) by means of logistic regressions. Specifically, three final models of a dichotomous outcome were constructed: one for cryptorchidism, one for hypospadias, and the third considering both malformations together. The Hosmer-Lemeshow test was used to assess the goodness of fit of the models. Their discriminatory accuracy (DA) was ascertained by estimating their areas under the receiver operating characteristic curves area under the curve (AUC) along with their 95% CI. RESULTS: Associations were found between advanced maternal age (OR adjusted = 1.82; 95% CI: 1.14-2.92), mother's consumption of anti-abortives (OR = 5.40; 95% CI: 1.40-38.5) and other drugs (OR = 2.02; 95% CI: 1.31-3.16) during pregnancy, maternal and paternal occupational exposure to EDCs (OR = 4.08; 95% CI: 2.03-8.96 and OR = 3.90; 95% CI: 2.41-6.48, respectively), fathers smoking (OR = 2.0; 95% CI: 1.33-2.99), and fathers with urological disorders (OR = 2.31; 95% CI: 1.15-4.90). Maternal and paternal high educational level could be protective of cryptorchidism (OR = 0.47; 95% CI: 0.28-0.76 and OR = 0.63; 95% CI: 0.42-0.93, respectively). The DA of the models for the whole sample (AUC = 0.75; 95% CI: 0.70-0.79) for cryptorchidism (AUC = 0.76; 95% CI: 0.71-0.82) and for hypospadias (AUC = 0.75; 95% CI: 0.69-0.81) was moderately high. CONCLUSIONS: Advanced age, some parental occupational exposure to EDCs, some drug consumption, smoking, and the father's history of urological disorders may increase risk and predict the developments of these malformations. Studies with higher samples sizes are needed to assess associations between individual EDC occupational exposures and drugs and these malformations.

[Mortality from postoperative complications (failure to rescue) after cardiac surgery in a university hospital]. / Mortalidad de las complicaciones postoperatorias (failure to rescue) tras cirugía cardiaca en un hospital universitario.

OBJECTIVE: This study analyses the rate of post-operative complications after cardiac surgery, the incidence of the failure to rescue (FR), and the relationship between complications and survival. METHODS: The study included a total of 2,750 adult patients operated of cardiac surgery between January 2003 and December 2009. An analysis was made of 9 post-operative complications. Multiple logistic regression analysis was used to find independent variables associated with any of the selected complications. Survival was analysed with Kaplan-Meyer survival estimates. A risk-adjusted Cox proportional regression model was used to find out which complications were associated with mid-term survival. RESULTS: Hospital mortality rate was 1.4% (95% CI: 1.0%-1.9%). Postoperative complications rate was 38.5% (36.7%-40.4%), and FR 3.6% (2.5%-4.9%). Urgent surgery (OR = 2.03; 1.52-2.72), chronic renal failure (OR = 1.50, 95%.CI: 1.25-1.80), and age ≥70 years (OR = 1.42; 1.20-1.68) were the variables that showed the highest strength of association with the selected complications. Survival at 5 years in the group of patients without complications was 93%, and in the group of patients with complications it was 83% (P<.0001). Postoperative complications associated with mid-term survival were pneumonia (HR = 2.6, 95% CI; 1.27-5.50), acute myocardial infarction (HR = 1.9; 1.10-2.30), and acute renal failure (HR = 1.7; 1.30-2.26). CONCLUSIONS: The incidence of complications after cardiac surgery is around 40%, and was associated with an increase in hospital mortality, although FR was very low (3.6%; 95% CI: 2.5-4.9).

[Consensus conference on providing information of adverse events to patients and relatives]. / Conferencia de consenso sobre información de eventos adversos a pacientes y familiares.

OBJECTIVE: To develop recommendations regarding «Information about adverse events to patients and their families¼, through the implementation of a consensus conference. MATERIAL AND METHODS: A literature review was conducted to identify all relevant articles, the major policies and international guidelines, and the specific legislation developed in some countries on this process. The literature review was the basis for responding to a series of questions posed in a public session. A group of experts presented the best available evidence, interacting with stakeholders. At the end of the session, an interdisciplinary and multi-professional jury established the final recommendations of the consensus conference. RESULTS: The main recommendations advocate the need to develop policies and institutional guidelines in our field, favouring the patient adverse events disclosure process. The recommendations emphasize the need for the training of professionals in communication skills and patient safety, as well as the development of strategies for supporting professionals who are involved in an adverse event. The assessment of the interest and impact of specific legislation that would help the implementation of these policies was also considered. CONCLUSIONS: A cultural change is needed at all levels, nuanced and adapted to the specific social and cultural aspects of our social and health spheres, and involves all stakeholders in the system to create a framework of trust and credibility in which the processing of information about adverse events may become effective.

[Patient safety in management contracts]. / La seguridad del paciente en los contratos de gestión.

Patient safety is becoming commonplace in management contracts. Since our experience in patient safety still falls short of other clinical areas, it is advisable to review some of its characteristics in order to improve its inclusion in these contracts. In this paper opinions and recommendations concerning the design and review of contractual clauses on safety are given, as well as reflections drawn from methodological papers and informal opinions of clinicians, who are most familiar with the nuances of safe and unsafe practices. After reviewing some features of these contracts, criteria for prioritizing and including safety objectives and activities in them, and key points for their evaluation are described. The need to replace isolated activities by systemic and multifaceted ones is emphasized. Errors, limitations and improvement opportunities observed when contracts are linked to indicators, information and adverse event reporting systems are analysed. Finally, the influence of the rules of the game, and clinicians behaviour are emphasised.

[Risk sharing agreements: with orphan drugs?]. / Contratos de riesgo compartido, ¿con medicamentos huérfanos?

OBJECTIVE: To summarize available information on share risk agreements (RSA) with orphan drugs (OD). METHODS: A bibliographic search was carried out in MEDLINE, EMBASE and INAHTA using 19 keywords and combinations thereof. Papers published as original, narrative and systematic reviews, editorials, commentaries, letters to the Editor, and special articles were included and reviewed. Public or private institutional reports or documents found in Google that contained relevant information were also reviewed. RESULTS: experience gained so far with RSA is scant. No published rigorous evaluations of outcomes of these agreements were found. It seems, however, that OD are suitable for introduction in clinical practice by means of RSA. There are two main types of RSA: financially based, and performance-outcome based. A number of theoretical advantages of SRA are described, as well as hurdles that hinder their design, implementation, and followup, and thus endangering their success. Very few RSA have clearly succeed so far. CONCLUSIONS: If thoroughly managed, RSA may reasonably contribute to value-based pricing of OD, improve their pharmacovigilance, knowledge about their comparative effectiveness, and to reducing uncertainty and its consequences on patients, industry, payers and clinicians. There are technical groups that can bring the essential knowledge to manage RSA in Spain. The challenge now is to be able to harmonize their assessments and appraisals, to put in motion the mechanisms needed to overcome those hurdles, and to provide them adequate political and institutional support.

Association between nutritional risk based on the NRS-2002 test and hospital morbidity and mortality.

OBJECTIVE: To analyse the relationship between the presence of malnutrition (MN), as measured by the NRS-2002 nutritional evaluation, and the rate of morbidity and mortality. DESIGN: Cross-sectional study. SETTING: Patients admitted to Mateu Orfila Hospital, the regional hospital for the island of Menorca, Spain. SUBJECTS: 1,075 patients who were admitted to Mateu Orfila Hospital (Menorca) who had laboratory studies and a nutritional risk (NR) evaluation available were studied. Those who had a clinical suspicion of MN or those at risk were studied. INTERVENTION: Demographic (age, gender) and clinical (current weight, normal weight, body mass index, weight loss, oral intake, presence of intestinal failure, fistula, renal failure, respiratory infection, urinary infection, hyperglycaemia, admission to the ICU, hospital stay, days of parenteral nutrition treatment and reason for admission) were collected during hospitalisation, as well as hospital mortality and mortality at 6 months following discharge. All underwent the NRS-2002 test. RESULTS: The mean patient age was 67.9 years and 58.3% were men. 62% of patients met the criteria for manutrition according to the NRS-2002 test. A statistically significant association was seen between malnutrition according to the NRS-2002 and intestinal failure, fistula, renal failure, respiratory infection, hyperglycemia, hospital mortality and mortality at 6 months. CONCLUSION: Malnutrition affects more than half of the patients who are admitted to a medium-long admission hospital and it is associated with increased morbidity and mortality. The results underscore the need to establish an update plan and preventative and therapeutic nutritional follow-up. These measures reduce the rate of avoidable complications and save the costs associated with them.
