Comparing the application of Health Information Technology in primary care in Denmark and Andalucía, Spain

BACKGROUND: It is generally acknowledged that Denmark is one, if not the, leading country in terms of the use of information technology by its primary care physicians. Other countries, notably excluding the United States and Canada, are also advanced in terms of electronic medical records in general practitioner offices and clinics. PURPOSE: This paper compares the status of primary care physician office computing in Andalucía to that of Denmark by contrasting the functionality of electronic medical records (EMRs) and the ability to electronically communicate clinical information in both jurisdictions. METHODS: A novel scoring system has been developed based on data gathered from databases held by the respective jurisdictional programs, and interviews with individuals involved in the deployment of the systems. The scoring methodology was applied for the first time in a comparison of the degree of automation in primary care physician offices in Denmark and the province of Alberta in Canada. It was also used to compare Denmark and New Zealand. This paper is the third offering of this method of scoring the adoption of electronic medical records in primary care office settings which hopefully may be applicable to other health jurisdictions at national, state, or provincial levels. RESULTS: Although similar in many respects, there are significant differences between these two relatively autonomous health systems which have led to the rates of uptake of physician office computing. Particularly notable is the reality that the Danish primary care physicians have individual "Electronic Medical Records" while in Andalucía, the primary care physicians share a common record which when secondary care is fully implemented will indeed be an "Electronic Health Record". CONCLUSION: It is clear that the diffusion of technology, within the primary care physician sector of the health care market, is subject to historical, financial, legal, cultural, and social factors. This tale of two places illustrates the issues, and different ways that they have been addressed.     

Clinical performance of the (1,3)-β-D-glucan assay in early diagnosis of nosocomial Candida bloodstream infections

Microbiological diagnosis of nosocomial candidemia is negatively affected by suboptimal culture yield. Alternative methods are not fully reliable as an aid in candidemia diagnosis. Recently, the detection of (1,3)-β-D-glucan (BG) has been shown to be very promising in this setting. We carried out a prospective study on the clinical usefulness of BG detection in early diagnosis of candidemia. BG detection was performed in patients with fever unresponsive to antibacterial agents and risk factors for candidemia. BG detection was done with the Fungitell test. A total of 152 patients were included in the study; 53 were proven to have candidemia, while in 52 patients candidemia was excluded on microbiological and clinical bases. The remaining 47 patients were considered to have possible candidemia. In summary, 41 of 53 candidemia patients (77.3%), 9 of 52 patients without candidemia (17.3%), and 38 of 47 patients with possible candidemia (80.8%) were positive in the BG assay. With these results, the sensitivity and the specificity of the assay were 77% and 83%, respectively. BG levels of >160 pg/ml were highly predictive of candidemia. In 36 of 41 patients with candidemia and positive BG testing, the BG assay was performed within 48 h from when the first Candida-positive blood sample for culture was drawn, thus allowing a possible earlier start of antifungal therapy. Based on these results, the BG assay may be used as an aid in the diagnosis of nosocomial candidemia. The timing of assay performance is critical for collecting clinically useful information. However, the test results should be associated with clinical data.     

Public attitudes to people with depression: have there been any changes over the last decade?

BACKGROUND: A consistent finding of representative surveys that were conducted in Germany in the early 1990s was that people with depression encountered a substantial amount of stigma and discrimination. The aim of this study was to examine whether public attitudes have improved over the last decade or not. METHODS: In 2001, a representative survey was carried out among the adult population of the "old" Federal Republic of Germany using the same methodology as in a previous survey in 1990. RESULTS: Regarding emotional reactions of the respondents towards people with depression, our findings are inconsistent. While there has been an increase in the readiness to feel pity and also a slight increase in the tendency to react aggressively, the expression of fear remained unchanged. The public's desire for social distance from people with depression was as strong in 2001 as it had been in 1990. CONCLUSION: The hypothesis of a change for the better regarding public attitudes towards depressed people is not supported by our findings. Further efforts are needed to reach this goal.     

Impact of changes in CLSI and EUCAST breakpoints for susceptibility in bloodstream infections due to extended-spectrum β-lactamase-producing Escherichia coli

The impact of recent changes in and discrepancies between the breakpoints for cephalosporins and other antimicrobials, as determined by CLSI and European Committee on Antimicrobial Susceptibility Testing (EUCAST), was analysed in patients with bloodstream infections caused by extended-spectrum β-lactamase (ESBL) producing Escherichia coli in Spain, was analysed. We studied a cohort of 191 episodes of bloodstream infection caused by ESBL-producing E. coli in 13 Spanish hospitals; the susceptibility of isolates to different antimicrobials was investigated by microdilution and interpreted according to recommendations established in 2009 and 2010 by CLSI, and in 2011 by EUCAST. Overall, 58.6% and 14.7% of isolates were susceptible to ceftazidime, and 35.1% and 14.7% to cefepime using the CLSI-2010 and EUCAST-2009/2011 recommendations, respectively (all isolates would have been considered resistant using the previous guidelines). Discrepancies between the CLSI-2010 and the EUCAST-2011 recommendations were statistically significant for other antimicrobials only in the case of amikacin (98.4% versus 75.9% of susceptible isolates; p <0.01). The results varied depending on the ESBL produced. No significant differences were found in the percentage of patients classified as receiving appropriate therapy, following the different recommendations. Four out of 11 patients treated with active cephalosporins according to CLSI-2010 guidelines died (all had severe sepsis or shock); these cases would have been considered resistant according to EUCAST-2011. In conclusion, by using current breakpoints, extended-spectrum cephalosporins would be regarded as active agents for treating a significant proportion of patients with bloodstream infections caused by ESBL-producing E. coli.     

Reactivity of (1?→?3)-β-d-glucan assay in bacterial bloodstream infections

To diagnose invasive fungal infections, the detection of (1 → 3)-β-d-glucan in serum has shown variable specificity, depending on the targeted population. Several circumstances for false-positive results of beta-glucan tests have been identified, among which are severe bacterial infections. In this study, we measured (1 → 3)-β-d-glucan by the Fungitell test in the serum of 62 patients (one serum sample tested per patient) for whom invasive fungal infection was not suspected: 19 control subjects and 43 patients with bacteraemia. The test was interpretable for 58 sera: all 19 control subjects had negative beta-glucan test; among the 39 bacteraemic patients, we report 16 false-positive results. For the 22 patients undergoing bacteraemia due to Gram-negative bacilli, we observed 13 false-positive results (59%). Among the 17 patients with bloodstream infection involving Gram-positive cocci, three false-positive tests were recorded, but none in the eight cases of Streptococcus pneumoniae bacteraemia. Statistical analysis showed that beta-glucan levels were significantly higher in patients with Gram-negative bacilli bloodstream infection in comparison to those with bacteraemia due to Gram-positive cocci. These results were independent from other previously described causes for false-positive beta-glucan tests. These data might help physicians to interpret positive beta-glucan detection when an invasive fungal infection is suspected, especially for patients with bacterial infections.     

Enteroviruses in Spain over the decade 1998–2007: Virological and epidemiological studies

BackgroundHuman enteroviruses (HEV) are the commonest cause of viral meningitis as well as other pathologies, therefore HEV characterization is important both in patient management and epidemiological investigation.ObjectivesA 10-year study of patients with enteroviral infection was carried out in Spain to determine the underlying etiology.Study designHEV were fully typed by microneutralisation tests and/or molecular methods.ResultsA collection of 86404 clinical samples were studied in several Spanish laboratories. These were collected from patients with different syndromes, mainly aseptic meningitis (AM), fever, respiratory diseases and acute flaccid paralysis. Of these, 6867 HEV were obtained. At the National Poliovirus Laboratory 2814 were serotypically characterised. Among non-polio enteroviruses, the eight main serotypes were Echovirus 30 (25%), Echovirus 6 (12.4%), Echovirus 13 (8.3%), Echovirus 11 (7.4%) and Echovirus 9 (4.7%), followed by Coxsackievirus B5 (4.2%) and Echovirus 7 and Coxsackievirus A9 (3.7%) each. In AM cases, Echovirus 30 was identified in 39% of them, followed by Echovirus 6 (14%). However, Echovirus 6 was mainly associated with respiratory disease (17%), followed by Echovirus 11 (10%). On the other hand, Echovirus 30, Echovirus 11 and Echovirus 6 contributed equally with 12% of each serotype in the cases of fever.ConclusionsThe present report complements previous data (Trallero et al.¹³), with the results of HEV incidence in Spain from 1998 to 2007. The surveillance described in this study provided valuable information as to which serotypes are in circulation, the emergence of new HEV and association with clinical manifestations.     

The outcome and timing of death of 17,767 nosocomial bloodstream infections in acute care hospitals in Finland during 1999–2014

Few studies covering all patient groups and specialties are available regarding the outcome of nosocomial bloodstream infections (BSI). We analyzed the role of patient characteristics and causative pathogens of nosocomial BSIs reported by the hospitals participating in national surveillance in Finland during 1999–2014, in terms of outcome, with particular interest in those leading to death within 2 days (i.e. early death). National nosocomial BSI surveillance was laboratory-based and hospital-wide. Data on nosocomial BSIs was collected by infection control nurses, and dates of death were obtained from the national population registry with linkage to national identity codes. A total of 17,767 nosocomial BSIs were identified; 557 BSIs (3%) were fatal within 2 days and 1150 (6%) within 1 week. The 1-month case fatality was 14% (2460 BSIs), and 23% of the deaths occurred within 2 days and 47% within 1 week. The patients who died early were older than those who survived >?28 days, and their BSIs were more often related to intensive care. Gram-positive bacteria caused over half of the BSIs of patients who survived, whereas gram-negative bacteria, especially Pseudomonas aeruginosa, caused more often BSIs of patients who died early, and fungi BSIs of patients who died within 1 week. A significant portion of patients with nosocomial BSIs died early, which underlines the importance of rapid recognition of BSI. Hospital-wide surveillance data of causative pathogens can be utilized when composing recommendations for empiric antimicrobial treatment in collaboration with clinicians, as well as when promoting infection prevention.     

Factors determining the variation in birth weight in Spain (1980–2010)

Background: Low weight and premature deliveries arouse clinical interest concerning the survival of newborns. The determinants of birth weight among Spanish natives and immigrants may differ. Research which considers maternal origin and associated factors such as age and parity is important.

Aim: This study analyses and models the influence of the rapid and intense arrival of immigrants in Spain on birth weight variation.

Method: Data on deliveries from the Spanish National Institute for Statistics (n = 9 443 882) are analysed regarding low birth weight, premature births and other variables. The inter-relation among these variables was interpreted by means of logistic regression models.

Results and conclusions: The birth weight has decreased since 1980 in Spain, but has slightly recovered in recent years. Meanwhile the percentage of foreign maternities increased to 17.3% in 2010. Logistic regression models assess the different influence of variables known to determine low birth weight (weeks of gestation, sex, etc.) and other maternal characteristics (age at delivery, professional activity, etc.). The progressively greater contribution of foreign women to total births in Spain and their differential numerical input to the various risk groups have slowed the pattern of reduction in the mean weight of newborns in this country.     

Changes in the incidence of Candida-related central line-associated bloodstream infections in pediatric intensive care unit: Could central line bundle have a role?

ObjectiveCandida species are among the most prevalent microorganisms in pediatric critical care units that cause central line-associated bloodstream infections. The goal of this study was to assess the therapeutic benefit of central line bundle for the prevention of Candida species-related bloodstream infections in pediatric intensive care units.DesignThe study covered the period from January 1, 2009, to December 31, 2019. Pre-bundle and bundle phases were included in the research. The Clinical Microbiology Laboratory's records revealed episodes of Candida-related central line-associated bloodstream infections.SettingThe study was conducted in the Dr. Behçet Uz Child Disease and Pediatric Surgery Training and Research Hospital's PICU (which has 24 beds and admits 350 patients per year).PatientsThis study included pediatric patients in the pediatric intensive care unit with non-tunneled central venous catheters.InterventionsIn the pediatric intensive care unit, a central line bundle was started.ResultsA total of 236 Candida-related central line-associated bloodstream infections were discovered during the study period. Non-albicans Candida accounted for 83.5% (197) of the total, whereas C.albicans accounted for 16.5%(39). During the pre-bundle period, 137 Candida species were isolated from the patients, while 99 Candida species were isolated during the bundle period. Candida-related central line-associated bloodstream infections dropped from 13.68 to 5.93 per 1000 CL-days after the central line bundle was used (p < 0.001).ConclusionsAccording to our findings, the central line bundle greatly reduced central line-associated Candida species bloodstream infections. Central line bundles are an effective scientific solution for preventing Candida-related central line-associated bloodstream infections in hospitals with high Candida prevalence.     

Has the prevalence of health care services use increased over the last decade (2001–2009) in elderly people? A Spanish population-based survey

Objectives(1) To describe the prevalence of general practitioner visits and hospitalization according to sex and age groups; (2) to identify which factors are independently associated with a higher use of health care services among elderly Spanish; and (3) to study the time trends in the prevalence of use of health care services 2001–2009.Study DesignObservational study. We analyzed data from the Spanish National Health Surveys conducted in 2001 (n = 21,058), 2003 (n = 21,650), 2006 (n = 29,478) and 2009 (n = 22,188). We included responses from adults aged 65 years and older.Outcome measuresThe main variables were the number of general practitioner visits in the last 4 weeks and hospitalization in the past year. We stratified the adjusted models by the main variables. We analyzed socio-demographic characteristics, health related variables, using multivariate logistic regression models.ResultsThe total number of subjects was 24,349 (15,041 woman, 9309 men). Women were significantly older than men (P < 0.001). Women had higher prevalence of general practitioner visits than men in all surveys. Men had significantly higher prevalence of hospitalizations than women in the years 2001, 2006 and 2009. When we adjusted the hospitalization by possible confounders using logistic regressions, men had a higher probability of being hospitalized than women (OR 1.53, 1.39–1.69). The variables that were significantly associated with a higher use of health care services were lower educational level, worse self-rated health, chronic conditions, polypharmacy, and the level of disability. The number of general practitioner visits among women and men significantly increased from 2001 to 2009 (women: OR 1.43, 1.27–1.61; men: OR 1.71, 1.49–1.97).ConclusionsThe current study revealed an increase in health care services utilization from 2001 to 2009 in the older Spanish population.

Hypertension-induced changes in the rat myocardium during the development of cardiac hypertrophy – a comparison between the left and the right ventricle

The hypertrophy of the cardiac muscle is one of the most significant maladaptive mechanisms activated in response to increased workload. It is associated with histological and ultrastructural alterations, changes in the quantitative parameters and the expression of different enzymes. While the structural and functional consequences of systemic hypertension on the left ventricle have been well evaluated, the right ventricle has received less attention. The aim of the present study was to analyse and compare the changes in the left and right ventricle during the development of cardiac hypertrophy initiated by systemic hypertension in different age groups of spontaneously hypertensive rats. Therefore, we studied the histology and ultrastructure of the cells of the myocardium, evaluated the immunohistochemical expression of the enzyme neuronal nitric oxide synthase and conducted a quantitative analysis of several morphometric parameters. We used three groups of spontaneously hypertensive rats. For the quantitative analysis we also used three age groups of age- and weight-matched control animals (normotensive Wistar rats). In both ventricles, we described cardiomyocytic hypertrophy, focal myocytolysis and increased collagen deposition in the interstitial space. Our observations on the ultrastructural level were associated with changes in the cardiomyocytic nuclei, the arrangement, maturity and organisation of the myofibrils, the localisation and ultrastructure of the mitochondria, the development and maturity of the intercalated discs, as well as changes in the components of the interstitium. The immunohistochemical expression of neuronal nitric oxide synthase in the left ventricle was stronger than that in the right ventricle across all age groups. The comparative quantitative analysis revealed that changes in the studied morphometric parameters in the two ventricles occurred disproportionately. In conclusion, the present study characterised the development of cardiac hypertrophy in response to systemic hypertension in both ventricles and demonstrated the involvement of the right ventricle.     

Molecular epidemiology and molecular characterization of respiratory syncytial viruses at a tertiary care university hospital in Catalonia (Spain) during the 2013–2014 season

BackgroundHuman respiratory syncytial virus (HRSV) is the main cause of lower respiratory tract infections among infants and young children.ObjectivesThe molecular epidemiology and characterization of HRSV strains detected at a Spanish tertiary hospital during the 2013–2014 season is reported.Study designPhylogenetic analysis and molecular characterization of HRSV laboratory-confirmed respiratory samples were performed, based on coding sequences of G and F proteins.ResultsHRSV infection was laboratory-confirmed in respiratory samples from 320 patients of which 223 (70%) were less than 2 years of age and none undergoing Palivizumab treatment. HRSV was detected at varying levels throughout the season with a maximum rate in the week 52/2013, right before the beginning of the influenza epidemic. Whilst both HRSV groups were found co-circulating, HRSV-B group clearly predominated. The phylogenetic analyses from 139 HVR-2 sequences revealed that most characterized strains belonged to ON1 and BA9 genotypes. Three different phylogenetic subgroups could be distinguished within these genotypes. In addition, three strains (out of the 52 randomly selected) were carrying amino acid substitutions in the epitope A of the F protein, one of them previously related to Palivizumab resistance.ConclusionsThe results of the present study highlight the importance of a continuous HRSV surveillance to monitor not only the introduction of new genotypes on circulation but also the emergence of viral variants with new genetic characteristics that can affect the antigenicity features and the susceptibility to the only current prophylaxis treatment and also for the future development of HRSV vaccines.     

Significance of methicillin–teicoplanin resistant Staphylococcus haemolyticus in bloodstream infections in patients of the Semmelweis University hospitals in Hungary

The purpose of this study was to quantify the impact of Staphylococcus haemolyticus in the epidemiology of the blood stream infection (BSI) and to characterize the rates and quantitative levels of resistance to antistaphylococcal drugs. During an eight-year period, 2967 BSIs of the patients hospitalized in different clinical departments of the Semmelweis University, Budapest, Hungary were analyzed. One hundred eighty-four were caused by S. haemolyticus, amounting to 6% of all infections. The antibacterial resistance of S. haemolyticus isolates was investigated by the broth microdilution method, vancomycin agar screen, population analysis profile and PCR for mecA, vanA and vanB genes detection. Epidemiological investigation was processed by determining phenotypic antibiotic resistance patterns and PFGE profiles. Extremely high MIC levels of resistance were obtained to oxacillin, erythromycin, clindamycin, gentamicin and ciprofloxacin. The incidence of teicoplanin reduced susceptibility revealed 32% without possessing either the vanA or vanB gene by the strains. PFGE revealed 56 well-defined genotypes indicating no clonal relationship of the strains. The propensity of S. haemolyticus to acquire resistance and its pathogenic potential in immunocompromised patients, especially among preterm neonates, emphasise the importance of species level identification of coagulase-negative staphylococci and routinely determine the MIC of proper antibacterial agents for these isolates.
