The Hospital Burden of Flu in Italy: a retrospective study on administrative data from season 2014-2015 to 2018-2019.

BACKGROUND: Every year in Italy, influenza affects about 4 million people. Almost 5% of them are hospitalised. During peak illness, enormous pressure is placed on healthcare and economic systems. This study aims to quantify the clinical and economic burden of severe influenza during 5 epidemic seasons (2014-2019) from administrative claims data. METHODS: Patients hospitalized with a diagnosis of influenza between October 2014, and April 2019, were analyzed. Clinical characteristics and administrative information were retrieved from health-related Administrative Databases (ADs) of 4 Italian Local Health Units (LHUs). The date of first admission was set as the Index Date (ID). A follow-up period of six months after ID was considered to account for complications and re-hospitalizations, while a lookback period (2 years before ID) was set to assess the prevalence of underlying comorbidities. RESULTS: Out of 2,333 patients with severe influenza, 44.1% were adults ≥ 65, and 25.6% young individuals aged 0-17. 46.8% had comorbidities (i.e., were at risk), mainly cardiovascular and metabolic diseases (45.3%), and chronic conditions (24.7%). The highest hospitalization rates were among the elderly (≥ 75) and the young individuals (0-17), and were 37.6 and 19.5/100,000 inhabitants/year, respectively. The average hospital stay was 8 days (IQR: 14 - 4). It was higher for older individuals (≥ 65 years, 11 days, [17 - 6]) and for those with comorbidities (9 days, [16 - 6]), p-value < 0.001. Similarly, mortality was higher in elderly and those at risk (p-value < 0.001). Respiratory complications occurred in 12.7% of patients, and cardiovascular disorders in 5.9%. Total influenza-related costs were €9.7 million with hospitalization accounting for 95% of them. 47.3% of hospitalization costs were associated with individuals ≥ 65 and 52.9% with patients at risk. The average hospitalisation cost per patient was € 4,007. CONCLUSIONS: This retrospective study showed that during the 2014-2019 influenza seasons in Italy, individuals of extreme ages and those with pre-existing medical conditions, were more likely to be hospitalized with severe influenza. Together with complications and ageing, they worsen patient's outcome and may lead to a prolonged hospitalization, thus increasing healthcare utilization and costs. Our data generate real-world evidence on the burden of influenza, useful to inform public health decision-making.

Costs and healthcare utilisation due to respiratory syncytial virus disease in paediatric patients in Italy: a systematic review.

OBJECTIVES: Respiratory syncytial virus (RSV) is a frequent cause of acute lower respiratory infection in children, imposing a substantial economic burden on healthcare systems. This systematic review aimed to assess the economic burden and healthcare utilisation of RSV in children aged 0-59 months in Italy. STUDY DESIGN: Systematic review. METHODS: A systematic search of PubMed, Embase, Scopus, and the International HTA Database, including studies published in English or Italian, was conducted between January 2000 and July 2022. Inclusion criteria required studies to be conducted in Italy and provide data on the economic costs and healthcare resource utilisation related to RSV infections. RESULTS: Out of 20,845 records screened, 18 articles met the inclusion criteria. Only one study provided comprehensive data on RSV disease costs, including hospitalisation, diagnostic tests, and medical procedures for infants with RSV-bronchiolitis. The mean cost per inpatient was higher for RSV-positive children (€5753.43 ± €2041.62) than that for RSV-negative children. Additionally, five studies reported a median length of hospital stay of 5 days for RSV-infected children, and four studies indicated a higher frequency of intensive care unit admissions for RSV-infected children than for those with other viral infections. CONCLUSIONS: This is the first systematic review to examine the economic burden and healthcare utilisation of RSV in children aged 0-59 months in Italy. While limited data were available, the findings underscore the urgency to conduct further research and gather additional evidence on the costs and healthcare resource utilisation associated with RSV infections. Such efforts are essential for informing the development of effective prevention strategies for paediatric RSV infections in Italy.

Cost-effectiveness for high dose quadrivalent versus the adjuvanted quadrivalent influenza vaccine in the Italian older adult population.

Objectives: To assess the cost-effectiveness of switching from adjuvanted quadrivalent vaccine (aQIV) to high-dose quadrivalent influenza vaccine (HD-QIV) in those aged ≥65 years from the Italian National Health Service perspective. Methods: We developed a decision tree model over a 1-year time-horizon to assess influenza-related costs and health outcomes. Two hospitalization approaches were considered: "hospitalization conditional on developing influenza" and "hospitalization possibly related to Influenza." The first approach considered only hospitalizations with influenza ICD-9-CM diagnosis codes. The second included hospitalizations for cardiorespiratory events possibly related to influenza to better capture the "hidden burden". Since comparative efficacy of high-dose quadrivalent influenza vaccine versus adjuvanted quadrivalent vaccine was lacking, we assumed relative efficacy versus a common comparator, standard-dose influenza quadrivalent vaccines (SD-QIV). We assumed the relative efficacy of HD-QIV vs. SD-QIV was 24.2 and 18.2% for the first and second hospitalization approaches, respectively, based on published information. Due to lack of comparative efficacy data for aQIV vs. SD-QIV, we assumed three different scenarios: 0, 6, and 12% relative efficacy in scenarios 1, 2, and 3, respectively. Results: For the first hospitalization approach, HD-QIV was a cost-effective alternative to aQIV in all scenarios at a willingness-to-pay threshold of €30,000 per Quality Adjusted Life Years. The incremental cost-effectiveness ratios across the scenarios were €7,301, €9,805, and €14,733, respectively, much lower than the willingness-to-pay per Quality Adjusted Life Years threshold. For the second hospitalization approach, HD-QIV was a dominant alternative to aQIV across all scenarios. The robustness of the results was confirmed in one-way and probabilistic sensitivity analyses. Conclusion: Switching to HD-QIV from aQIV for the older adult in Italy would improve health-related outcomes, and would be cost-effective or cost saving.

SABR for Early Non-Small Cell Lung Cancer: Changes in Pulmonary Function, Dyspnea, and Quality of Life.

PURPOSE: The aim of this study was to report pulmonary function tests (PFTs) and clinician-reported and patient-reported quality-of-life (QoL) outcomes on a cohort of patients with non-small cell lung cancer (NSCLC) treated with SABR. METHODS AND MATERIALS: A total of 119 patients with NSCLC were treated with SABR in the prospective cohort SSBROC study of patients with T1-T2N0M0 NSCLC. PFTs and QoL measures were obtained at baseline pretreatment and at 6-month intervals. Here we report on the 6- to 18-month time points. Analysis of covariance (ANCOVA) methods adjusting for baseline analyzed potential predictors on outcomes of PFTs and patient-reported dyspnea at 18 months. RESULTS: The only statistically significant decline in PFTs was seen in forced expiratory volume in 1 second (FEV1) at 18 months post-SABR, with a decline of -0.11 L (P = .0087; 95% CI, -0.18 to -0.02). Of potential predictors of decline, only a 1-unit increase in smoking pack-years resulted in a -0.12 change in diffusing capacity for carbon monoxide (P = .026; 95% CI, -0.02 to -0.23) and a 0.003 decrease in FEV1 (P = .026; 95% CI, -0.006 to -0.0004). For patient-reported outcomes, statistically significant worsening in both the European Organisation for Research and Treatment of Cancer Quality of Life Core Questionnaire (QLQ-C30 Version 3) and the lung module (QLQ-LC13) dyspnea scores occurred at the 18-month time point, but not earlier. No potential predictors of worsening dyspnea were statistically significant. There was no statistically significant decline in clinician-reported outcomes or global QoL scores. CONCLUSIONS: We found a statistically significant decline in FEV1 at 18 months posttreatment. Smoking pack-years was a predictor for decline in diffusing capacity for carbon monoxide and FEV1 at 18 months. Worsening of patient-reported dyspnea scores was observed, consistent with the expected progression of lung comorbid disease.

Acquired resistome and plasmid sequencing of mcr-1 carrying MDR Enterobacteriaceae from poultry and their relationship to STs associated with humans.

OBJECTIVES: To investigate the acquired resistome in 18 colistin-resistant Escherichia coli isolated from different poultry farms in Lebanon, analyse Inc plasmids associated with mcr and assess potential transmission to humans. METHODS: A total of 18 E. coli were recovered from poultry faeces collected from different poultry farms in Lebanon. Broth microdilution (BMD) assay was performed to determine the antimicrobial resistance profiles. WGS was used to identify the genetic determinants behind the resistance in these isolates. RESULTS: BMD results showed that all of the 18 isolates were colistin resistant. Furthermore, resistance to trimethoprim/sulfamethoxazole was the most recorded among the isolates and only one isolate was resistant to cefepime. Sequencing results showed that the isolates were distributed into seven different STs and that the most abundant was ST1140. The number of antimicrobial resistant determinants ranged from 4 to 21 among the 18 isolates, with tet(A) and floR being the most frequent. Moreover, a total of 15 different plasmid replicon types were identified. The mcr-1 gene was shown to be predominantly located on IncX4 plasmids. Additionally, two isolates harboured the IncI2-type self-conjugative plasmid. CONCLUSIONS: The findings show that mcr and other important resistance determinants occur in MDR E. coli isolated poultry farms in Lebanon. The occurrence of mcr on mobile plasmids and the zoonotic potential and clinical relevance of some strains highlight a risk of transmission to humans.

Collaborative implementation of stereotactic ablative body radiotherapy: A model for the safe implementation of complex radiotherapy techniques in Australia.

INTRODUCTION: Stereotactic ablative radiotherapy (SABR) for lung cancer is a modality of treatment that has improved outcomes for lung cancer patients. However, radiotherapy for lung cancer is underutilized and fewer than half of elderly patients with non-small cell lung cancer (NSCLC) receive active treatment. The purpose of this study is to report on a collaboration in implementing an NSCLC SABR (stereotactic ablative body radiation) program safely, efficiently, and uniformly across several centers, including regional sites. The first aim of this paper is to detail the collaboration and implementation that started in 2013 and is ongoing. The second aim of this paper is to document early toxicities and quality of life outcomes. METHOD: A tripartite approach was used to develop the protocol and networks required for the implementation of SABR across multiple sites in NSW. Departments starting the programmes were supported and physics credentialing with central site submission was required before commencing the treatment. Additional ongoing support was available via an email discussion group involving all members of the collaboration. RESULTS: Between July 22, 2013 and February 22, 2016, 41 patients were enrolled with 34 patients in active follow up. The toxicity profile so far is similar to those of published studies with no appreciable effect on quality of life outcomes. CONCLUSION: The collaboration formed an effective framework in facilitating the implementation of SABR across several sites in NSW and could be used as a model for the safe and uniform implementation of new technologies in Australia.

Comparing the Outcomes of Stereotactic Ablative Radiotherapy and Non-Stereotactic Ablative Radiotherapy Definitive Radiotherapy Approaches to Thoracic Malignancy: A Systematic Review and Meta-Analysis.

Stereotactic ablative body radiotherapy (SABR) is popular because of the high rates of local control with low toxicity seen in lung cancer patients. In this study we compared clinically significant toxicity and overall survival for SABR and non-SABR definitive radiotherapy (conformal radiotherapy) patients. A PUBMED search of all human, English language articles on SABR and non-SABR radically treated early stage lung cancer patients was performed until June 2016. Results of these searches were filtered in accordance with a set of eligibility criteria and analyzed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Eighty-seven SABR and 25 non-SABR articles were reviewed. There was no significant difference in pneumonitis rates between patients receiving SABR (11.4%; 95% confidence interval [CI], 9.7-13.3) and non-SABR treatment (14.4%; 95% CI, 10.6-18.8; P = .20). Esophagitis was the most common mediastinal toxicity reported with 15% of all non-SABR patients versus 1% of all SABR patients reporting developing Grade ≥2 toxicity. The proportion of patient surviving at 2 and 3 years was superior for SABR patients (P < .001). Treatment-related deaths were rare (approximately 1% for both treatments). Both radiotherapy approaches had low rates of pneumonitis, mediastinal toxicity, and treatment-related deaths. However, significant heterogeneity in the patient population and study regimens limit the power of direct comparison, showing that further high-quality studies are required to define the role of SABR in higher risk and operable patients.

Accident proneness and impulsiveness in an Italian group of burn patients.

There is controversy about the existence of a predisposition to burn incidents (accident proneness). Our objective was to examine, in a group of burn patients, the conditions or "unconscious" subjective predisposition, the presence of impulsiveness that may have contributed to bringing about the "burn" event, and to assess the presence of psychiatric diagnoses and specific characteristics of temperament. 25 consecutive burn patients were interviewed by using specific psychometric tests. The sample was divided into two groups: "control" group (N=10), composed of subjects who had accidentally been involved in the incident and "case" group (N=15) composed of subjects who had very likely and more or less "knowingly" put themselves at risk of injury. We observed a marked statistically significant difference with case group subjects appearing to be more impulsive than the ones in control group. Higher levels of impulsiveness may predispose case group patients to a greater risk of burn. Our survey also seems to reveal a relationship between impulsiveness and the proneness of some subjects to burns.
