Main causes of hospitalization in people with Angelman syndrome.

BACKGROUND: The objective was to describe the main causes of hospitalization in people with Angelman syndrome (AS). METHOD: Population-based cross-sectional study in the Community of Madrid (CM), Spain. The information source for AS cases was the information system for rare diseases in the CM. Variables related to hospitalization, for the period 2006-2014, were the following: number of episodes, outcome, main cause, length of stay and type of admission. Main causes of hospitalization were described by age group and sex. RESULTS: The most frequent causes of hospitalization were the following: oral-dental care (28.9%), seizures (19.6%), orthopaedic problems (14.4%) and acute respiratory disorders (12.4%). The percentage of hospitalizations was higher for oral-dental care in women and for orthopaedic problems in men (p-value <.05). Hospitalizations for an acute respiratory disorder were higher in adults (p-value <.05). CONCLUSIONS: Some differences in the causes of hospitalization of people with AS were observed by sex and age.

Trends in socioeconomic inequalities in preventable mortality in urban areas of 33 Spanish cities, 1996-2007 (MEDEA project).

BACKGROUND: Preventable mortality is a good indicator of possible problems to be investigated in the primary prevention chain, making it also a useful tool with which to evaluate health policies particularly public health policies. This study describes inequalities in preventable avoidable mortality in relation to socioeconomic status in small urban areas of thirty three Spanish cities, and analyses their evolution over the course of the periods 1996-2001 and 2002-2007. METHODS: We analysed census tracts and all deaths occurring in the population residing in these cities from 1996 to 2007 were taken into account. The causes included in the study were lung cancer, cirrhosis, AIDS/HIV, motor vehicle traffic accidents injuries, suicide and homicide. The census tracts were classified into three groups, according their socioeconomic level. To analyse inequalities in mortality risks between the highest and lowest socioeconomic levels and over different periods, for each city and separating by sex, Poisson regression were used. RESULTS: Preventable avoidable mortality made a significant contribution to general mortality (around 7.5%, higher among men), having decreased over time in men (12.7 in 1996-2001 and 10.9 in 2002-2007), though not so clearly among women (3.3% in 1996-2001 and 2.9% in 2002-2007). It has been observed in men that the risks of death are higher in areas of greater deprivation, and that these excesses have not modified over time. The result in women is different and differences in mortality risks by socioeconomic level could not be established in many cities. CONCLUSIONS: Preventable mortality decreased between the 1996-2001 and 2002-2007 periods, more markedly in men than in women. There were socioeconomic inequalities in mortality in most cities analysed, associating a higher risk of death with higher levels of deprivation. Inequalities have remained over the two periods analysed. This study makes it possible to identify those areas where excess preventable mortality was associated with more deprived zones. It is in these deprived zones where actions to reduce and monitor health inequalities should be put into place. Primary healthcare may play an important role in this process.

Social differences in avoidable mortality between small areas of 15 European cities: an ecological study.

BACKGROUND: Health and inequalities in health among inhabitants of European cities are of major importance for European public health and there is great interest in how different health care systems in Europe perform in the reduction of health inequalities. However, evidence on the spatial distribution of cause-specific mortality across neighbourhoods of European cities is scarce. This study presents maps of avoidable mortality in European cities and analyses differences in avoidable mortality between neighbourhoods with different levels of deprivation. METHODS: We determined the level of mortality from 14 avoidable causes of death for each neighbourhood of 15 large cities in different European regions. To address the problems associated with Standardised Mortality Ratios for small areas we smooth them using the Bayesian model proposed by Besag, York and Mollié. Ecological regression analysis was used to assess the association between social deprivation and mortality. RESULTS: Mortality from avoidable causes of death is higher in deprived neighbourhoods and mortality rate ratios between areas with different levels of deprivation differ between gender and cities. In most cases rate ratios are lower among women. While Eastern and Southern European cities show higher levels of avoidable mortality, the association of mortality with social deprivation tends to be higher in Northern and lower in Southern Europe. CONCLUSIONS: There are marked differences in the level of avoidable mortality between neighbourhoods of European cities and the level of avoidable mortality is associated with social deprivation. There is no systematic difference in the magnitude of this association between European cities or regions. Spatial patterns of avoidable mortality across small city areas can point to possible local problems and specific strategies to reduce health inequality which is important for the development of urban areas and the well-being of their inhabitants.

Prevalence of Leber hereditary optic neuropathy in the Community of Madrid (Spain), estimation with a capture-recapture method.

BACKGROUND: Leber hereditary optic neuropathy (LHON) typically presents in young adults as bilateral painless subacute visual loss. Prevalence data are scarce. The aim of this study was to examine the validity of different ascertainment sources used in population-based rare diseases registries to detect cases, and to explore the impact of a capture-recapture method in the estimation of the prevalence of LHON in the Autonomous Community of Madrid (ACM) in 2022. METHODS: Descriptive cross-sectional population-based study. Potential LHON cases were detected by automatic capture from the healthcare information sources usually explored for the Regional Registry for Rare Diseases (SIERMA). Ophthalmologists provided data from their clinical registry. Positive predictive values (PPV) and sensitivity with 95% confidence intervals (CI) were estimated. Global and by sex prevalences were calculated with confimed cases and with those estimated by the capture-recapture method. RESULTS: A total of 102 potential LHON cases were captured from healthcare information sources, 25 of them (24.5%) finally were confirmed after revision, with an overall PPV of 24.5% (95%CI 17.2-33.7). By source, the electronic clinical records of primary care had the highest PPV (51.2, 95%CI 36.7-65.4). The ophthalmologists clinical registry provided 22 cases, 12 of them not detected in the automatic capture sources. The clinical registry reached a sensitivity of 59.5% (95%CI 43.5-73.6) and the combination of automatic capture sources reached a 67.6% (95%CI: 51.5-80.4). The total confirmed cases were 37, with a mean age of 48.9 years, and a men: women ratio of 2.4:1. Genetic information was recovered in 27 cases, with the m.3460 mutation being the most frequent (12 cases). The global prevalence was 0.55 cases/100,000 inhabitants (95%CI 0.40-0.75), and with the capture-recapture method reached 0.79 cases/100,000 (95%CI 0.60-1.03), a 43.6% higher, 1.15 cases/100,000 (95%CI 0.83-1.58) in men and 0.43 cases/100,000 (95%CI 0.26-0.70) in women. CONCLUSIONS: The prevalence of LHON estimated in the ACM was lower than in other European countries. Population-based registries of rare diseases require the incorporation of confirmed cases provided by clinicians to asure the best completeness of data. The use of more specific coding for rare diseases in healthcare information systems would facilitate the detection of cases. Further epidemiologic studies are needed to assess potential factors that may influence the penetrance of LHON.

Do socioeconomic inequalities in mortality vary between different Spanish cities? a pooled cross-sectional analysis.

BACKGROUND: The relationship between deprivation and mortality in urban settings is well established. This relationship has been found for several causes of death in Spanish cities in independent analyses (the MEDEA project). However, no joint analysis which pools the strength of this relationship across several cities has ever been undertaken. Such an analysis would determine, if appropriate, a joint relationship by linking the associations found. METHODS: A pooled cross-sectional analysis of the data from the MEDEA project has been carried out for each of the causes of death studied. Specifically, a meta-analysis has been carried out to pool the relative risks in eleven Spanish cities. Different deprivation-mortality relationships across the cities are considered in the analysis (fixed and random effects models). The size of the cities is also considered as a possible factor explaining differences between cities. RESULTS: Twenty studies have been carried out for different combinations of sex and causes of death. For nine of them (men: prostate cancer, diabetes, mental illnesses, Alzheimer's disease, cerebrovascular disease; women: diabetes, mental illnesses, respiratory diseases, cirrhosis) no differences were found between cities in the effect of deprivation on mortality; in four cases (men: respiratory diseases, all causes of mortality; women: breast cancer, Alzheimer's disease) differences not associated with the size of the city have been determined; in two cases (men: cirrhosis; women: lung cancer) differences strictly linked to the size of the city have been determined, and in five cases (men: lung cancer, ischaemic heart disease; women: ischaemic heart disease, cerebrovascular diseases, all causes of mortality) both kinds of differences have been found. Except for lung cancer in women, every significant relationship between deprivation and mortality goes in the same direction: deprivation increases mortality. Variability in the relative risks across cities was found for general mortality for both sexes. CONCLUSIONS: This study provides a general overview of the relationship between deprivation and mortality for a sample of large Spanish cities combined. This joint study allows the exploration of and, if appropriate, the quantification of the variability in that relationship for the set of cities considered.

Pandemic influenza A (H1N1) 2009 in Madrid, Spain: incidence and characteristics in immigrant and native population.

BACKGROUND: Some immigrants and refugees might be more vulnerable than other groups to pandemic influenza because of pre-existing health and social disparities, migration history and living conditions. The objective of this study was to compare, between the immigrant and autochtonous population, the incidence and characteristics of influenza cases consulting in primary care (PC) and severe influenza cases. METHODS: Descriptive cross-sectional study of influenza episodes registered in PC and severe influenza cases reported between 1 May 2009 and 22 May 2010, by gender and origin. Age-adjusted rates were calculated and the association between origin and chronic pathology, pregnancy, delay in admission to hospital and admission to intensive care units (ICU) was analyzed by logistic regression and generalized linear models. RESULTS: The influenza rate in PC, adjusted by age, was lower for immigrant population (2396.3, 95% confidence interval (95% CI) 2362.5-2430.0 vs. 2795.9, 95% CI 2780.4-2811.5 per 100, 000). The difference between severe influenza rates by origin was not statistically significant. Chronic conditions were less common in immigrant population. In severe influenza cases, pregnancy was more common in immigrant women, and the probability of admission to ICU was higher in men from Central and Eastern Europe (prevalence ratio (PR) 8.44, 95% CI 2.81-25.40) and North African women (PR 3.30, 95% CI 1.09-10.05). CONCLUSION: Differences in influenza rates were detected by origin. This information could be useful for new pandemic wave management purposes, in addition to targetting future investigations. Pandemic influenza preparedness and response plans should incorporate specific actions to improve immigrants' access to health services and to decrease cultural barriers.

Bayesian factor analysis to calculate a deprivation index and its uncertainty.

BACKGROUND: Procedures for calculating deprivation indices in epidemiologic studies often show some common problems because the spatial dependence between units of analysis and uncertainty of the estimates is not usually accounted for. This work highlights these problems and illustrates how spatial factor Bayesian modeling could alleviate them. METHODS: This study applies a cross-sectional ecological design to analyze the census tracts of 3 Spanish cities. To calculate the deprivation index, we used 5 socioeconomic indicators that comprise the deprivation index calculated in the MEDEA project. The deprivation index was estimated by a Bayesian factor analysis using hierarchical models, which takes the spatial dependence of the study units into account. We studied the relationship between this index and the one obtained using principal component analysis. Various analyses were carried out to assess the uncertainty obtained in the index. RESULTS: A high correlation was observed between the index obtained and the non-Bayesian index, but this relationship is not linear and there is disagreement between the methods when the areas are grouped according to quantiles. When the deprivation index is calculated using summary statistics based on the posterior distributions, the uncertainty of the index in each census tract is not taken into account. Failure to take this uncertainty into account may result in misclassification bias in the census tracts when these are grouped according to quantiles of the deprivation index. CONCLUSIONS: Not taking uncertainty into account may result in misclassification bias in the census tracts. This bias could interfere in subsequent analyses that include the deprivation index. Our proposal provides another tool for identifying groups with greater deprivation and for improving decision-making for public policy planning.

Lifestyle interventions for cancer prevention in primary care: Differences between family physicians and nursing professionals.

RATIONALE, AIMS, AND OBJECTIVES: Prevention offers the most cost-effective long-term strategy for cancer control. The objective of this study was to ascertain opinions, attitudes, and professional practices towards cancer prevention among primary care professionals and to assess differences between family physicians (FP) and nursing professionals (NP). METHOD: A cross-sectional study was performed in 2012 in the Community of Madrid. A random sample of 3586 professionals received an online questionnaire about opinions/attitudes, training, and interventions in cancer prevention. The chi-square test was used to analyse the association of the profession with all the variables. Factors associated with the usual practice of individual, group, and community interventions were analysed using multivariate logistic regression, with separate models for FP and NP. RESULTS: The response rate was 39.4% (N = 1413). Approximately 90% of the participants attributed "sufficient/high" utility to individualized counselling. NP attributed higher utility to group and community interventions than FP (70.1% vs 60.1% and 64.9% vs 57.7%, respectively, P-value < 0.01). The usual practice of group and community interventions was more frequent among NP. The practice of group and community interventions was associated with knowledge of resources for prevention, specific training in group interventions, and the utility attributed to these methods. Among FP, the ability to dispense effective health advice and the utility attributed to this advice were associated with the usual practice of the three interventions. CONCLUSIONS: Group and community interventions are rarely practised, especially among FP. Actions targeting improved ability and knowledge could lead to higher involvement in the promotion of health. It would also be necessary to intervene in the examination of the utility of such interventions.

Coverage and predictors of influenza vaccination in patients with cystic fibrosis in a campaign with a mobile phone text messaging intervention.

Annual influenza vaccination is considered the best protection against influenza infection. We analyzed the influenza vaccine coverage (IVC) in cystic fibrosis (CF) patients and evaluated the factors associated with the IVC, including the effect of text-message/SMS reminders. We performed a cross-sectional study in the Community of Madrid (Spain) in 2015. The target population was people with CF older than 6 months of age at the beginning of the flu vaccination campaign. The IVC was calculated according to the study variables. A total of 445 CF patients were analyzed. In 2015, IVC reached 67.9% and was higher in children and women. The main factor associated with flu vaccination was having been vaccinated in the previous campaign (aOR 14.36; IC95%: 8.48-24.32). The probability of being vaccinated after receiving the SMS was more than twice than for those who did not receive it, although no statistical significance was reached. In conclusion the IVC of patients with CF is high, but it still has room for improvement. SMS reminders sent to CF patients might improve influenza vaccine uptake.

Request for HIV serology in primary care: A survey of medical and nursing professionals. / Solicitud de serologías de VIH en atención primaria: encuesta a profesionales de Medicina y de Enfermería.

INTRODUCTION: In the Community of Madrid there is 42.7% late HIV diagnosis. Primary care is the gateway to the health system and the frequency of serological tests requested by these professionals is unknown. The objectives were to establish the frequency of requests for HIV serology by medical and nursing primary care professionals in the Community of Madrid and the factors associated with these requests. METHOD: An 'on-line' survey was conducted, asking professionals who participated in the evaluation study of strategies to promote early diagnosis of HIV in primary care in the Community of Madrid (ESTVIH) about the number of HIV-serology tests requested in the last 12 months. The association between HIV-serology requesting and the sociodemographic and clinical practice characteristics of the professionals was quantified using adjusted odds ratios (aOR) according to logistic regression. RESULTS: 264 surveys (59.5% physicians). Eighty-two point two percent of medical and 18.7% of nursing professionals reported requesting at least one HIV-serology in the last 12 months (median: 15 and 2 HIV-serology request, respectively). The doctors associated the request with: being male (aOR: 2.95; 95% CI: 0.82-10.56), being trained in pre-post HIV test counselling (aOR: 2.42; 95% CI: 0.84-6.93) and the nurses with: age (<50 years; aOR: 2.75; 95% CI: 0.97-7.75), and number of years working in primary care (>13 years; aOR: 3.02; 95% CI: 1.07-8.52). CONCLUSION: It is necessary to promote HIV testing and training in pre-post HIV test counselling for medical and nursing professionals in primary care centres.

[Constructing a deprivation index based on census data in large Spanish cities(the MEDEA project)]. / Construcción de un índice de privación a partir de datos censales en grandes ciudades españolas (Proyecto MEDEA).

OBJECTIVES: a) To describe the methodology used to construct a deprivation index by census tract in cities, to identify the tracts with the least favorable socioeconomic conditions, and b) to analyze the association between this index and overall mortality. METHODS: Several socioeconomic indicators (Census 2001) were defined by the census tracts of the following cities: Barcelona, Bilbao, Madrid, Seville and Valencia. The correlations with the standardized mortality ratio (1996-2003), and the dimensionality of the socioeconomic indicators were studied. Finally, the selected indicators were aggregated in an index, in which the results of the factor loadings from extraction of a factor by principal components were used as weighting values. RESULTS: The indicators with the strongest correlations with overall mortality were those related to work, education, housing conditions and single parent homes. In the analysis of dimensionality, a first dimension appeared that contained indicators related to work (unemployment, manual and eventual workers) and education (insufficient education overall and in young people). In all the cities studied, the index created with these 5 indicators explained more than 75% of their variability. The correlations between this index and mortality generally showed higher values than those obtained with each indicator separately. CONCLUSIONS: The deprivation index proposed could be a useful instrument for health planning as it detects small areas of large cities with unfavorable socioeconomic characteristics and is associated with mortality. This index could contribute to the study of social inequalities in health in Spain.

Suicidal behaviour characteristics and factors associated with mortality in the hospital setting. / Características de la conducta suicida y factores asociados a su mortalidad en el ámbito hospitalario.

INTRODUCTION: Suicide is a major public health problem worldwide, and an approach is necessary due to its high potential for prevention. This paper examines the main characteristics of people admitted to hospitals in the Community of Madrid (Spain) with suicidal behaviour, and the factors associated with their hospital mortality. MATERIAL AND METHODS: A study was conducted on patients with E950-E959 codes of suicide and self-inflicted injuries of the International Classification of Diseases, Ninth Revision, Clinical Modification, contained in any diagnostic field of the minimum basic data set at hospital discharge between 2003 and 2013. Sociodemographic, clinical and health care variables were assessed by uni- and multivariate logistic regression analysis in the evaluation of factors associated with hospital mortality. RESULTS: Hospital suicidal behaviour predominates in women (58.7%) and in middle-age. Hospital mortality is 2.2% (1.6% in women and 3.2% in men), increasing with age. Mental disorders are detected 3-4 times more in secondary diagnoses. The main primary diagnosis (>74%) is poisoning with substances, with lower mortality (∼1%) than injury by hanging and jumping from high places (≥12%), which have the highest numbers. Other factors associated with increased mortality include different medical comorbidities and severity of the injury, while length of stay and mental disorders are protective factors. Type of hospital, poisoning, and Charlson index are associated differently with mortality in men and women. CONCLUSIONS: Hospitalised suicidal acts show a low mortality, mainly related to comorbidities and the severity of injuries.

A feasibility study for 3 strategies promoting HIV testing in primary health care in Madrid, Spain (ESTVIH project).

RATIONALE AND OBJECTIVES: Late diagnosis of HIV infection is a public health problem. Framed by the international guidelines for improving HIV testing, in 2014, the Spanish Ministry of Health published a guide of recommendations to promote early diagnosis of HIV in health care settings. In the Community of Madrid, in order to implement these recommendations, we defined 3 new HIV testing strategies in primary health care. The objectives of this study were to know the interest of professionals and the acceptability for patients towards these strategies. METHODS: We performed a quasi-experimental study to assess the feasibility of the implementation of new strategies (indicator condition, risk based, and universal offer) to promote early detection of HIV infection in the framework of the ESTVIH project. The centres participating in this project were randomly chosen among centres located in the health areas with the highest incidence of HIV infection. The feasibility was assessed in 6 centres. We considered outcomes by strategy in relation to the participation of professionals (family physician and nursing) and patients. RESULTS: Overall, 56.9% of eligible professionals agreed to take part in the study; however, the percentage of professionals who recruited patients was 25.9%. This percentage was higher in the indicator condition strategy (47.2%, versus 18.5% in the universal offer and 14.3% in the risk-based strategy, P-value < 0.05). The test uptake percentage was greater than 80%, and there were no statistically significant differences between strategies. CONCLUSION: Different strategies promoting HIV testing in primary care had different acceptability among professionals and similar among patients. At the end of the ESTVIH project, these results will be complemented with others related to the contribution of each strategy to improving the early diagnosis of HIV infection.

Externalities and article citations: experience of a national public health journal (Gaceta Sanitaria).

PURPOSE: The purpose of the study was to analyze the determinants of citations such as publication year, article type, article topic, article selected for a press release, number of articles previously published by the corresponding author, and publication language in a Spanish journal of public health. METHODS: Observational study including all articles published in Gaceta Sanitaria during 2007-2011. We retrieved the number of citations from the ISI Web of Knowledge database in June 2013 and also information on other variables such as number of articles published by the corresponding author in the previous 5 years (searched through PubMed), selection for a press release, publication language, article type and topic, and others. RESULTS: We included 542 articles. Of these, 62.5% were cited in the period considered. We observed an increased odds ratio of citations for articles selected for a press release and also with the number of articles published previously by the corresponding author. Articles published in English do not seem to increase their citations. CONCLUSIONS: Certain externalities such as number of articles published by the corresponding author and being selected for a press release seem to influence the number of citations in national journals.

Characteristics of herpes zoster-associated hospitalizations in Madrid (SPAIN) before vaccine availability.

OBJECTIVES: This study aimed to estimate the frequency of hospitalizations due to herpes zoster (HZ) and to describe their clinical characteristics by sex and age group. METHODS: Descriptive population-based cross-sectional study of hospital admissions due to HZ from 2003 to 2013 among residents in the Autonomous Community of Madrid. Sex, age, comorbidities, length of stay and outcomes were collected and described. Crude and age-adjusted cumulative incidence rates, and stratified by sex and age, were estimated. Robust Poisson regression analysis was used to calculate the incidence rate ratios by age group. RESULTS: 2039 hospitalizations were identified (51.0% in women). Complicated HZ caused 48.7% of them (50.9% in women). The hospitalization rate was 2.98/100,000 person-years and 7.19/1000 cases of HZ in primary care. Both rates were significantly higher in men, except in the extreme age groups. An immunosuppression-associated comorbidity was identified in 32.8% of the cases and was less common in patients ≥75 years of age. The median length of stay was 6 days, and in-hospital mortality was 1.4%. CONCLUSIONS: Hospitalization rates due to HZ were higher in men and increased with age. In two out of every three cases, a comorbidity that potentially caused immunosuppression could not be identified. These cases could benefit from vaccination.

[Monitoring social determinants of health]. / La vigilancia de los determinantes sociales de la salud.

Public health surveillance is the systematic and continuous collection, analysis, dissemination and interpretation of health-related data for planning, implementation and evaluation of public health initiatives. Apart from the health system, social determinants of health include the circumstances in which people are born, grow up, live, work and age, and they go a long way to explaining health inequalities. A surveillance system of the social determinants of health requires a comprehensive and social overview of health. This paper analyses the importance of monitoring social determinants of health and health inequalities, and describes some relevant aspects concerning the implementation of surveillance during the data collection, compilation and analysis phases, as well as dissemination of information and evaluation of the surveillance system. It is important to have indicators from sources designed for this purpose, such as continuous records or periodic surveys, explicitly describing its limitations and strengths. The results should be published periodically in a communicative format that both enhances the public's ability to understand the problems that affect them, whilst at the same time empowering the population, with the ultimate goal of guiding health-related initiatives at different levels of intervention.

[Study protocol on the effect of the economic crisis on mortality and reproductive health and health inequalities in Spain]. / Protocolo del estudio sobre el efecto de la crisis económica en la mortalidad, la salud reproductiva y las desigualdades en salud en España.

The aim is to present the protocol of the two sub-studies on the effect of the economic crisis on mortality and reproductive health and health inequalities in Spain. Substudy 1: describe the evolution of mortality and reproductive health between 1990 and 2013 through a longitudinal ecological study in the Autonomous Communities. This study will identify changes caused by the economic crisis in trends or reproductive health and mortality indicators using panel data (17 Autonomous Communities per study year) and adjusting Poisson models with random effects variance. Substudy 2: analyse inequalities by socioeconomic deprivation in mortality and reproductive health in several areas of Spain. An ecological study analysing trends in the pre-crisis (1999-2003 and 2004-2008) and crisis (2009-2013) periods will be performed. Random effects models Besag York and Mollié will be adjusted to estimate mortality indicators softened in reproductive health and census tracts.

Place of death and associated factors among patients with amyotrophic lateral sclerosis in Madrid (Spain).

Our objectives were to analyse the place of death, its temporal trend and associated sociodemographic factors among patients with amyotrophic lateral sclerosis (ALS) resident in the Autonomous Community of Madrid. This was a population based cross-sectional study of deaths from ALS (ICD-10 code G12.2) from 2003 to 2011, included in regional death statistics. The sociodemographic variables were age, gender, marital status, place of residence and socioeconomic level. Logistic regressions were performed to identify factors associated with death in hospital, and odds ratios (OR) with 95% confidence intervals (CI) were calculated. Joinpoint models were used to analyse annual trends for death in hospital. Of 1035 patients who died of ALS, 56.1% died in a hospital, 30.4% at home, 8.3% in a residential home and it was unknown for 5.1%. The percentage of deaths in hospital was lower in older and in single people than in married ones (55.0% and 61.9%, respectively; ORa 0.74, 95% CI 0.57-0.97). This percentage increased progressively as socioeconomic level fell (66.3% in Q5 compared to 49.6% in Q1, ORa 2.03, 95% CI 1.36-3.02). A significant increase in the percentage of deaths in hospital was observed. In conclusion, factors such as age, marital status or socioeconomic level play a part in the place of death of those with ALS.

Temporal trends in herpes zoster-related hospitalizations in Madrid (Spain), 2003-2013.

OBJECTIVES: This study aimed to estimate herpes zoster (HZ) related hospitalization rates in the Autonomous Community of Madrid (Spain), considering both total and complicated cases, and to analyze their temporal trends by sex and age. METHODS: Population based cross-sectional study of all hospital admissions with an HZ diagnosis in any position from 2003 to 2013. Annual crude, age-adjusted and age-specific hospitalization rates were calculated by sex and year. Joinpoint Regression models were used to analyze time trends. RESULTS: The incidence of hospitalizations with HZ increased significantly during the study period from 10.81 to 16.97 per 100,000 person-year, with an average annual rise of 2.80%. The rate of hospitalization of complicated HZ increased from 4.67 to 8.99 per 100,000 person-year. No 'breakthrough points' of the time trends were detected. The proportion of complicated HZ was similar in both sexes, and increased from 43.2% to 53.0%. By age and sex significant increases affecting women from age 85 and men from age 75 and in the group of 45-64 years were observed. CONCLUSIONS: Hospitalizations related to HZ are increasing, with a significant rise of complicated cases. Long term and more detailed studies are required to monitor HZ.
