Risk of Acute Kidney Injury Based on Vancomycin Target Trough Attainment Strategy: Area-Under-the-Curve-Guided Bayesian Software, Nomogram, or Trough-Guided Dosing.

BACKGROUND: Guidelines support area-under-the-curve (AUC) monitoring for vancomycin dosing which may lower overall doses and reduce acute kidney injury (AKI). OBJECTIVE: The aim of this study was to compare incidence of AKI across 3 vancomycin dosing modalities: AUC-targeted Bayesian pharmacokinetic software, AUC-targeted empiric dosing nomogram, and trough-guided dosing using clinical pharmacists' judgment. METHODS: This retrospective study included adult patients with a pharmacy dosing consult who received ≥1 dose of vancomycin and ≥1 serum vancomycin level documented between January 1, 2018, and December 31, 2019. Patients with baseline serum creatinine ≥2 mg/dL, weight ≥100 kg, receiving renal replacement therapy, AKI prior to vancomycin therapy, or vancomycin ordered only for surgical prophylaxis were excluded. The primary analysis was incidence of AKI adjusted for baseline serum creatinine, age, and intensive care unit admission. A secondary outcome was adjusted incidence of an abnormal trough value (<10 or >20 µg/mL). RESULTS: The study included 3459 encounters. Incidence of AKI was 21% for Bayesian software (n = 659), 22% for the nomogram (n = 303), and 32% for trough-guided dosing (n = 2497). Compared with trough-guided dosing, incidence of AKI was lower in the Bayesian (adjusted odds ratio [OR] = 0.72, 95% confidence interval [CI]: 0.58-0.89) and the nomogram (adjusted OR = 0.71, 95% CI: 0.53-0.95) groups. Compared with trough-guided dosing, abnormal trough values were less common in the Bayesian group (adjusted OR = 0.83, 95% CI: 0.69-0.98). CONCLUSION AND RELEVANCE: Study results suggest that use of AUC-guided Bayesian software reduces the incidence of AKI and abnormal trough values compared with trough-guided dosing.

The Superblock model: A review of an innovative urban model for sustainability, liveability, health and well-being.

INTRODUCTION: Current urban and transport planning practices have significant negative health, environmental, social and economic impacts in most cities. New urban development models and policies are needed to reduce these negative impacts. The Superblock model is one such innovative urban model that can significantly reduce these negative impacts through reshaping public spaces into more diverse uses such as increase in green space, infrastructure supporting social contacts and physical activity, and through prioritization of active mobility and public transport, thereby reducing air pollution, noise and urban heat island effects. This paper reviews key aspects of the Superblock model, its implementation and initial evaluations in Barcelona and the potential international uptake of the model in Europe and globally, focusing on environmental, climate, lifestyle, liveability and health aspects. METHODS: We used a narrative meta-review approach and PubMed and Google scholar databases were searched using specific terms. RESULTS: The implementation of the Super block model in Barcelona is slow, but with initial improvement in, for example, environmental, lifestyle, liveability and health indicators, although not so consistently. When applied on a large scale, the implementation of the Superblock model is not only likely to result in better environmental conditions, health and wellbeing, but can also contribute to the fight against the climate crisis. There is a need for further expansion of the program and further evaluation of its impacts and answers to related concerns, such as environmental equity and gentrification, traffic and related environmental exposure displacement. The implementation of the Superblock model gained a growing international reputation and variations of it are being planned or implemented in cities worldwide. Initial modelling exercises showed that it could be implemented in large parts of many cities. CONCLUSION: The Superblock model is an innovative urban model that addresses environmental, climate, liveability and health concerns in cities. Adapted versions of the Barcelona Superblock model are being implemented in cities around Europe and further implementation, monitoring and evaluation are encouraged. The Superblock model can be considered an important public health intervention that will reduce mortality and morbidity and generate cost savings for health and other sectors.

Cooperative housing under a grant-of-use in Catalonia and health: pre-post analysis.

BACKGROUND: Housing is considered a social determinant of health. In Catalonia and Spain, ensuring affordable housing is challenging and cooperative housing under a grant-of-use emerges as an alternative, challenging traditional housing models. This study aims to quantify its impact on health before and after moving to the cooperative house. METHODS: A longitudinal study of individuals in cooperative housing projects in Catalonia (July 2018-April 2023) was conducted. Data, including sociodemographic, housing information, and health-related details, were collected through baseline and follow-up surveys. RESULTS: Seventy participants (42 women, 28 men) showed positive changes in housing conditions during follow-up. Improved perceptions of health, mental health, and social support were observed. Despite limitations in sample size and short follow-up, initial findings suggest improvements in health. CONCLUSIONS: Cooperative housing under a grant-of-use in Catalonia appears promising for improving health and living conditions. Further research is warranted to explore its full potential as an alternative amid housing challenges in the region.

Effectiveness of a Road Traffic Injury Prevention Intervention in Reducing Pedestrian Injuries, Barcelona, Spain, 2002-2019.

This study aimed to evaluate the effectiveness of the Safe Routes to School (SRTS) intervention in Barcelona, Spain, at reducing the number of road traffic collisions and injuries in the school environment. It was a pre-post, quasi-experimental evaluation with a matched comparison group. Road traffic injuries were significantly reduced in the intervention schools-especially among school-age pedestrians-but not in the comparison schools. The SRTS program significantly improved road safety among children. (Am J Public Health. 2023;113(5):495-499. https://doi.org/10.2105/AJPH.2022.307216).

Tackling health inequalities in a public health organization: the case of the Barcelona Public Health Agency.

BACKGROUND: Municipalities are important actors in the implementation of policies to tackle health inequalities, which requires political will, the availability of financial support, and technical and human resources. With the aim of aligning with local government political priorities, in 2017 the Barcelona Public Health Agency (Agència de Salut Pública de Barcelona, henceforth ASPB), which is responsible for the public health functions of the city, launched a strategy to improve the approach to tackling health inequalities in all its services. The objectives of this study were to show how social health inequalities were addressed in the ASPB from 2017 to 19 and to describe which actions were proposed after a participatory process aiming to create a plan to systematically incorporate health inequalities in ASPB actions. METHODS: The ASPB has 304 workers, 8 directors and 20 services or departments. Participatory methodologies were carried out: 1) semi-structured interviews with department heads (N = 12, 60%); 2) world cafe workshops open to a group of workers (N = 63, 37%); 3) a Quick and Colorful voting session open to a group of workers (N = 108, 63%); and 4) Hanlon matrix with 19 actions to be prioritized (N = 12 services, 60%). RESULTS: Semi-structured interviews and world cafe workshops provided 40 potential actions. After a step by step process of participatory prioritization, seven lines of action emerged: 1) to make progress in collaborative networking; 2) to promote policy evaluation; 3) to increase the ability of the ASPB to evaluate policies to reduce health inequalities; 4) to incorporate the axes of inequalities in all ASPB products; 5) to improve information on vulnerable groups; 6) to incorporate the gender perspective; and 7) to participate in an internal training plan to address health inequalities. CONCLUSIONS: The participation of ASPB public health professionals and staff allowed the organization to design a shared plan of actions to address health inequalities. This experience could be useful for other municipalities whose political agendas include tackling inequalities in health.

The BabyTok Project: Examining the Feasibility and Acceptability of a Light-Touch Social Media Project for Infant-Toddler Teachers.

High-quality early care and education is a known protective factor for infants and toddlers who experience early childhood poverty, especially for early communication outcomes. However, the quality of care is variable in the United States, and efforts to increase the quality of interactions is impeded by cost and high rates of turnover in the field. In this paper, we explore a low-cost, light touch social media intervention that uses the TikTok platform to increase infant-toddler teachers' (ITTs) knowledge of early communication and social interactions while validating the important role that ITTs play in the lives of young children. We use a mixed method, pre-post design to explore the feasibility and acceptability of the BabyTok project from the vantage point of the ITT participants. Teachers offered positive feedback about the content, delivery of the intervention through TikTok and the impact on their feelings about their role in helping young children learn.

Remdesivir for Severe Coronavirus Disease 2019 (COVID-19) Versus a Cohort Receiving Standard of Care.

BACKGROUND: We compared the efficacy of the antiviral agent, remdesivir, versus standard-of-care treatment in adults with severe coronavirus disease 2019 (COVID-19) using data from a phase 3 remdesivir trial and a retrospective cohort of patients with severe COVID-19 treated with standard of care. METHODS: GS-US-540-5773 is an ongoing phase 3, randomized, open-label trial comparing two courses of remdesivir (remdesivir-cohort). GS-US-540-5807 is an ongoing real-world, retrospective cohort study of clinical outcomes in patients receiving standard-of-care treatment (non-remdesivir-cohort). Inclusion criteria were similar between studies: patients had confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, were hospitalized, had oxygen saturation ≤94% on room air or required supplemental oxygen, and had pulmonary infiltrates. Stabilized inverse probability of treatment weighted multivariable logistic regression was used to estimate the treatment effect of remdesivir versus standard of care. The primary endpoint was the proportion of patients with recovery on day 14, dichotomized from a 7-point clinical status ordinal scale. A key secondary endpoint was mortality. RESULTS: After the inverse probability of treatment weighting procedure, 312 and 818 patients were counted in the remdesivir- and non-remdesivir-cohorts, respectively. At day 14, 74.4% of patients in the remdesivir-cohort had recovered versus 59.0% in the non-remdesivir-cohort (adjusted odds ratio [aOR] 2.03: 95% confidence interval [CI]: 1.34-3.08, P < .001). At day 14, 7.6% of patients in the remdesivir-cohort had died versus 12.5% in the non-remdesivir-cohort (aOR 0.38, 95% CI: .22-.68, P = .001). CONCLUSIONS: In this comparative analysis, by day 14, remdesivir was associated with significantly greater recovery and 62% reduced odds of death versus standard-of-care treatment in patients with severe COVID-19. CLINICAL TRIALS REGISTRATION: NCT04292899 and EUPAS34303.

Treatment of Coronavirus Disease 2019 (COVID-19) Patients with Convalescent Plasma.

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2, has spread globally, and no proven treatments are available. Convalescent plasma therapy has been used with varying degrees of success to treat severe microbial infections for >100 years. Patients (n = 25) with severe and/or life-threatening COVID-19 disease were enrolled at the Houston Methodist hospitals from March 28, 2020, to April 14, 2020. Patients were transfused with convalescent plasma, obtained from donors with confirmed severe acute respiratory syndrome coronavirus 2 infection who had recovered. The primary study outcome was safety, and the secondary outcome was clinical status at day 14 after transfusion. Clinical improvement was assessed on the basis of a modified World Health Organization six-point ordinal scale and laboratory parameters. Viral genome sequencing was performed on donor and recipient strains. At day 7 after transfusion with convalescent plasma, nine patients had at least a one-point improvement in clinical scale, and seven of those were discharged. By day 14 after transfusion, 19 (76%) patients had at least a one-point improvement in clinical status, and 11 were discharged. No adverse events as a result of plasma transfusion were observed. Whole genome sequencing data did not identify a strain genotype-disease severity correlation. The data indicate that administration of convalescent plasma is a safe treatment option for those with severe COVID-19 disease.

Health Effects of Housing Insecurity and Unaffordability in the General Population in Barcelona, Spain.

While the negative effects of housing insecurity and unaffordability on health are well known, most of the studies in Spain have focused on very specific social groups so their findings cannot be extrapolated to the general population. The aim of this study is to assess the effects of housing stress and risk of displacement due to economic reasons, and their combined effect, on the mental and physical health of the general population from a middle-income neighborhood of Barcelona. We conducted a cross-sectional study using a household health survey which included respondents from a representative sample of 1202 non-institutionalized residents (> 18 years old) of the Horta neighborhood. We carried out a descriptive analysis, estimated the prevalence of poor mental and self-rated health (stratifying by the independent variables) and fitted robust Poisson regression models to estimate the effects of housing stress (HS) and the risk of forced displacement (RD) on self-rated health and mental health (GHQ-12). All analyses were stratified by sex. We found a higher likelihood of poor general and mental health among people affected by HS and/or RD compared to those not affected by HS and/or RD. A graded effect of HS and RD emerged mainly on mental health, even after adjusting by socioeconomic variables and housing tenure. The serious problem of housing insecurity and unaffordability in Spain is a widespread public health issue. Evidence-based public policies to improve well-being and health of people under this threat are urgently needed.

Role of Rapid Diagnostics in Diagnosis and Management of Patients With Sepsis.

Delayed administration of active anti-infective therapy is associated with increased rates of adverse events, mortality, and costs among sepsis patients. Inherent limitations of conventional culture identification methods and the lengthy turnaround time of antimicrobial susceptibility testing are significant barriers to the timely delivery of life-saving therapy, particularly among antibiotic-resistant infections. Culture-independent diagnostic techniques that detect pathogens and antimicrobial resistance genes within clinical samples present a tremendous benefit to timely diagnosis and management of patients. Improved outcomes for rapid intervention with rapid diagnostics have been documented and include decreased mortality rates, decreased health care delivery costs, and faster delivery of appropriate therapeutics.

Public Transport Strikes and Their Relationships With Air Pollution, Mortality, and Hospital Admissions.

There is limited suggestive evidence of relationships between public transport strikes and either increased air pollution or worse population health. In this study we aimed to assess whether public transport strikes were associated with increases in health events (overall, cardiovascular and respiratory mortality, and cardiovascular and respiratory hospitalizations). We also explored whether air pollution mediated those associations. We used data from the city of Barcelona (Spain) for the period 2005-2016 on strikes, health events, and ambient air pollution (nitrogen dioxide, nitrogen monoxide, particulate matter (PM) with an aerodynamic diameter ≤10 µm, PM with an aerodynamic diameter ≤2.5µm, PM with an aerodynamic diameter ≤1µm, number of particles with a diameter greater than 5 nm per cm3 (particle number concentration), and black carbon). We used linear and quasi-Poisson regression models to explore the associations between air pollution and public transport strikes and between public transport strikes and health outcomes. We also investigated potential causal mediation by air pollution. Overall, this study suggested that public transport strikes are associated with increased overall mortality, respiratory mortality, and respiratory hospitalizations. However, our findings suggest that such increases are not mediated by the increase in air pollution. Our results indicate the need to further investigate these relationships and potential mechanisms.

Impact of Chlorhexidine Bathing on Antimicrobial Utilization in Surgical Intensive Care Unit.

BACKGROUND: This secondary analysis compared antimicrobial utilization among surgical intensive care unit patients randomized to every other day chlorhexidine bathing (chlorhexidine) versus daily soap and water bathing (soap-and-water) using data from the CHlorhexidine Gluconate BATHing trial. MATERIALS AND METHODS: Antimicrobial utilization was quantified using defined daily dose (DDD)/100 patient-days and agent-days/100 patient-days for systemic antimicrobials. Antivirals (except oseltamivir), antiparasitics, and prophylaxis agents were excluded. The 2018 anatomic therapeutic chemical/DDD index was used to calculate DDD. Agent-days were calculated as the sum of calendar days where antimicrobials were administered. Patient-days were defined as time patients were at risk for health care-acquired infections plus up to 14 d. Primary analyses were conducted using linear regression adjusted for baseline Acute Physiology and Chronic Health Evaluation II scores. RESULTS: Of 325 CHlorhexidine Gluconate BATHing trial patients, 312 (157 in soap-and-water and 155 in chlorhexidine) were included. The median (interquartile range) of total antimicrobial DDD/100 patient-days was 135.4 (75.2-231.8) for soap-and-water and 129.9 (49.2-215.3) for chlorhexidine. The median (interquartile range) of total antimicrobial agent-days/100 patient-days was 155.6 (83.3-243.2) for soap-and-water and 146.7 (66.7-217.4) for chlorhexidine. After adjusting for Acute Physiology and Chronic Health Evaluation II scores, chlorhexidine bathing was associated with a nonsignificant reduction in total antimicrobial DDD/100 patient-days (-3.9; 95% confidence interval, -33.9 to 26.1; P = 0.80) and total antimicrobial agent-days/100 patient-days (-10.3; 95% confidence interval, -34.7 to 14.1; P = 0.41). CONCLUSIONS: Compared with daily soap and water bathing, every other day chlorhexidine bathing did not significantly reduce total antimicrobial utilization in surgical intensive care unit patients.

Longitudinal assessment of T cell inhibitory receptors in liver transplant recipients and their association with posttransplant infections.

Current immunosuppression regimens in organ transplantation primarily inhibit T cells. However, T cells are also critical in protective immunity, especially in immune-compromised patients. In this study, we examined the association of T cell dysfunction, as marked by expression of T cell exhaustion molecules, and posttransplant infections in a cohort of liver transplant patients. We focused on Programmed Death 1 (PD-1) and T cell Ig- and mucin-domain molecule 3 (Tim-3), which are potent co-inhibitory receptors, and their persistent expression often leads to T cell dysfunction and compromised protective immunity. We found that patients with the highest expression of PD-1 +Tim-3+ T cells in the memory compartment before transplantation had increased incidence of infections after liver transplantation, especially within the first 90 days. Longitudinal analysis in the first year showed a strong association between variability of PD-1 and Tim-3 expression by T cells and infectious episodes in transplant patients. Furthermore, T cells that expressed PD-1 and Tim-3 had a significantly reduced capacity in producing interferon (IFN)-γ in vitro, and this reduced IFN-γ production could be partially reversed by blocking PD-1 and Tim-3. Interestingly, the percentage of Foxp3+ regulatory T cells in liver transplant patients was stable in the study period. We concluded that the functional status of T cells before and after liver transplantation, as shown by PD-1 and Tim-3 expression, may be valuable in prognosis and management of posttransplant infections.

Towards valid 'serious non-fatal injury' indicators for international comparisons based on probability of admission estimates.

BACKGROUND: Governments wish to compare their performance in preventing serious injury. International comparisons based on hospital inpatient records are typically contaminated by variations in health services utilisation. To reduce these effects, a serious injury case definition has been proposed based on diagnoses with a high probability of inpatient admission (PrA). The aim of this paper was to identify diagnoses with estimated high PrA for selected developed countries. METHODS: The study population was injured persons of all ages who attended emergency department (ED) for their injury in regions of Canada, Denmark, Greece, Spain and the USA. International Classification of Diseases (ICD)-9 or ICD-10 4-digit/character injury diagnosis-specific ED attendance and inpatient admission counts were provided, based on a common protocol. Diagnosis-specific and region-specific PrAs with 95% CIs were calculated. RESULTS: The results confirmed that femoral fractures have high PrA across all countries studied. Strong evidence for high PrA also exists for fracture of base of skull with cerebral laceration and contusion; intracranial haemorrhage; open fracture of radius, ulna, tibia and fibula; pneumohaemothorax and injury to the liver and spleen. Slightly weaker evidence exists for cerebellar or brain stem laceration; closed fracture of the tibia and fibula; open and closed fracture of the ankle; haemothorax and injury to the heart and lung. CONCLUSIONS: Using a large study size, we identified injury diagnoses with high estimated PrAs. These diagnoses can be used as the basis for more valid international comparisons of life-threatening injury, based on hospital discharge data, for countries with well-developed healthcare and data collection systems.

Postoperative antimicrobials after lung transplantation and the development of multidrug-resistant bacterial and Clostridium difficile infections: an analysis of 500 non-cystic fibrosis lung transplant patients.

BACKGROUND: Broad-spectrum antimicrobials are given prophylactically post-transplant, although these agents are a risk factor for multidrug-resistant (MDR) infections and Clostridium difficile infection (CDI). This study aimed to determine whether an association exists between the duration of antimicrobials given early post-transplant and the development of MDR infections or CDI. METHODS: A single-center retrospective analysis was performed on lung transplants from September 2009 to August 2014. Patients were excluded for cystic fibrosis (CF) or postoperative survival less than 30 d. Qualifying infections were defined as any new positive MDR bacterial culture or C. difficile assay from postoperative day 7-90 d after a broad-spectrum antimicrobial. RESULTS: A total of 500 patients, 61% male, were identified, median age of 62 yr. MDR infections occurred in 169 (34%) and CDI in 31 (6%). Non-ICU days were associated with a decreased risk of MDR/CDI (OR 0.891, p = 0.0002), and duration of Gram-positive antimicrobials (OR 1.073, p = 0.0219) was associated with an increased risk. CONCLUSIONS: One-third (34%) of non-CF lung transplants develop MDR infections and 6% develop CDI within 90 d of postoperative antimicrobials. The duration of Gram-positive antimicrobials may increase the risk of MDR/CDI, while early transfer from the ICU may have a protective effect.

Effect of neighbourhood motorization rates on walking levels.

BACKGROUND: Motorized traffic may discourage people walking. This study analyses the influence of motorization on pedestrian mobility in the neighbourhoods of a European city, controlling for environmental, sociodemographic, mobility and road safety characteristics of the neighbourhood in which each trip was made. METHODS: Cross-sectional ecological study using the 38 neighbourhoods of Barcelona as the unit of analysis. Mobility information was obtained from the 2006 Daily Mobility Survey. Walking rates were calculated for 32.343 men and women who made walking trips, per 1000 men and women who made trips in the 38 neighbourhoods. Data were aggregated to calculate the total number of motorized trips made in each neighbourhood. ß coefficients and their confidence intervals were calculated using Poisson regression, in order to study the relationship between walking and motorization, in the different tertiles of motorization and adjusting for contextual factors and their corresponding interactions with motorization. RESULTS: Levels of motorization in the neighbourhood negatively influence walking, even when environmental variables of the neighbourhood are considered. In men we observe a gradient whereby walking rates fall as motorization rises (ß = -0.248; P < 0.001 and ß = -0.363; P < 0.001 in the second and third quartiles of motorization, respectively). In the case of women we find that only high levels of motorization have a negative influence on the rates of women who walk. (ß = -0.256; P < 0.001). CONCLUSION: Motorized traffic discourages people walking. Motorization is a modifiable environment-related factor which should be taken into account when designing policies to promote safe active travel.

Review of rapid diagnostic tests used by antimicrobial stewardship programs.

Rapid microbiologic tests provide opportunities for antimicrobial stewardship programs to improve antimicrobial use and clinical and economic outcomes. Standard techniques for identification of organisms require at least 48-72 hours for final results, compared with rapid diagnostic tests that provide final organism identification within hours of growth. Importantly, rapid microbiologic tests are considered "game changers" and represent a significant advancement in the management of infectious diseases. This review focuses on currently available rapid diagnostic tests and, importantly, the impact of rapid testing in combination with antimicrobial stewardship on patient outcomes.

PBP2a mutations causing high-level Ceftaroline resistance in clinical methicillin-resistant Staphylococcus aureus isolates.

Ceftaroline is the first member of a novel class of cephalosporins approved for use in the United States. Although prior studies have identified eight ceftaroline-resistant methicillin-resistant Staphylococcus aureus (MRSA) isolates in Europe and Asia with MICs ranging from 4 to 8 mg/liter, high-level resistance to ceftaroline (>32 mg/liter) has not been described in MRSA strains isolated in the United States. We isolated a ceftaroline-resistant (MIC > 32 mg/liter) MRSA strain from the blood of a cystic fibrosis patient and five MRSA strains from the respiratory tract of this patient. Whole-genome sequencing identified two amino acid-altering mutations uniquely present in the ceftaroline-binding pocket of the transpeptidase region of penicillin-binding protein 2a (PBP2a) in ceftaroline-resistant isolates. Biochemical analyses and the study of isogenic mutant strains confirmed that these changes caused ceftaroline resistance. Thus, we identified the molecular mechanism of ceftaroline resistance in the first MRSA strain with high-level ceftaroline resistance isolated in the United States.

Incidence trends of injury among the elderly in Spain, 2000-2010.

BACKGROUND: The significant growth in the elderly population expected in the coming years demands a thorough and up-to-date understanding of the incidence of injuries in this group for purposes of prevention polices and their evaluation. The aim of this study was to describe the incidence of injuries in hospital inpatients over 64 years of age in Spain, stratified by sex, age group, and the severity and mechanism of injury, and to analyse trends in incidence during the period 2000-2010. METHODS: Descriptive trends study using data from the National Hospital Discharge Register. The dependent variable was the number of hospital discharges with injury. Stratified incidence rates were calculated per 100,000 inhabitants. Trends, in terms of annual per cent change, were assessed using Poisson regression with discharge year as the independent variable. RESULTS: Rates of injury were higher among women than men, increased with age in both sexes, with individuals aged ≥85 years having a fivefold greater risk than those aged 65-69 years. During the period 2000-2010, incidence increased annually by 1.1% in men and 0.9% in women aged 75-79 years, 2.3% and 1.6% in 80-84-year-olds and 3.3% and 2.4% in ≥85-year-olds, respectively. The incidence of all levels of injury severity and all mechanisms of injury increased during the study period, except for traffic injuries, which decreased. CONCLUSIONS: Incidence of injury in the elderly is rising, particularly in older individuals, indicating that the increase in the number of hospitalisations is not a consequence of population aging only.
