Vaccination status among COVID-19 patients and duration of Polymerase Chain Reaction test positivity: evaluation of immunization schedule and type of vaccine.

Background: The introduction of the vaccine against SARS-CoV-2 has represented a cornerstone in the containment of the pandemic. Our aim was to assess the vaccination schedules in relation to the infection free interval and to the duration of positivity in case of infection. Study design: This study involves the SARS-CoV-2 infected people managed by the Local Health Authority ASL 1 Abruzzo. The data collected included: vaccine administration date, vaccine type, information on the Polymerase Chain Reaction test positivity, and demographic variables, such as age and sex. Methods: The duration of Polymerase Chain Reaction test positivity was assessed in relation to the vaccination status, the vaccine type and the time interval between the last vaccination dose and the first nasopharyngeal positive swab over the considered period. Results: The infection duration (DAYS) was significantly shorter in subjects vaccinated with a booster dose than unvaccinated subjects (12.8 vs 14.6; p<0.0001) and subjects vaccinated with the primary series only (12.8 vs 14.1; p<0.0001). Duration of PCR positivity was shorter with heterologous immunisation than with other vaccination schedules (p=0.0317). Conclusions: This study highlights, in a large cohort of patients, the association between vaccination schedule and the response to infection.

Reduction of in-hospital non-COVID-19 pneumonia in stroke patients during the COVID-19 pandemic.

BACKGROUND: Measures adopted to contain the spread of SARS-CoV-2 could have led to a reduction in the rate of non-COVID-19 infections. We assessed whether a similar reduction was present in patients with stroke. METHODS: We performed a hospital-based study nested in a prospective population-based registry. We compared prevalence of infections and in-hospital mortality in subjects admitted for acute stroke between the first pandemic year (study period, from March 2020 to February 2021) and the pre-pandemic year (control period, from March 2019 to February 2020). Infections were reported as pneumonia (PNA), urinary tract infections (UTI), and any infection (INF). RESULTS: From the control (n = 677) to the study period (n = 520), the prevalence of INF decreased from 11.5 to 4.6% (p < 0.001) and that of PNA decreased from 6.9 to 2.5% (p = 0.001). No changes in in-hospital mortality and length of hospital stay were observed between the two periods. CONCLUSIONS: The observed reduction of in-hospital pneumonias in patients with stroke was likely attributable to the use of protective measures and limitation of hospital visits. Maintaining some of those measures in the long term may contribute to control infections in hospitalized patients with stroke.

Fall of viral and bacterial pneumonia hospitalizations following COVID-19 pandemic mitigation strategies: a central Italian Region retrospective study.

Community-Acquired Pneumonia (CAP) represents one of the first causes of hospitalization and death in the elderly all over the world and weighs heavily on public health system. Since the beginning of the COVID-19 (CoronaVirus Disease-19) pandemic, everybody's behavior was forced to change, as the result of a global lockdown strategy and the obligation of using personal protection equipment (PPE). We aimed to evaluate how the mitigation strategies adopted to fight SARS-CoV-2 (Severe Acute Respiratory Coronavirus Syndrome 2) infection have influenced hospitalizations due to CAP in two different Local Health Boards (LHBs) of central Italy. We considered two main periods of observation: before and after the national start of lockdown, in two Abruzzo's LHBs. We analyzed 19,558 hospital discharge records of bacterial and viral CAP. Excluding SARS-CoV2 infection, a significant decrease in CAP hospitalizations was observed. Through the analysis of Diagnosis Related Group (DRG) values, we highlighted a significant saving of founds for the Regional Health Service. The enactment of social distancing measures to contain COVID-19 spread, brought down admissions for bacterial and viral pneumonia. Our study emphasizes that costs for hospitalizations due to CAP could be drastically reduced by mask wearing and social distancing.

Clinical usefulness of Edinburgh CT criteria in patients with lobar intracerebral hemorrhage.

BACKGROUND: Identifying the cause of intracerebral hemorrhage (ICH) is relevant to optimize its management. We aimed to assess the applicability and utility of the Edinburgh CT criteria for cerebral amyloid angiopathy (CAA) in an unselected cohort of hospitalized patients. PATIENTS AND METHODS: We retrospectively applied the Edinburgh criteria to the first available brain CTs of patients hospitalized for a first-ever lobar ICH in the district of L'Aquila from 2011 to 2017. ICH characteristics and outcomes were compared according to the presence of the Edinburgh CT criteria, including associated subarachnoid hemorrhage (aSAH) and finger-like projections (FLPs). The outcome of ICH in-hospital mortality was assessed with multivariate logistic regression analysis. We adopted the Edinburgh criteria, age, NIHSS and Glasgow Coma Scale scores, systolic blood pressure, antiplatelet treatment, ICH volume, and intraventricular extension on admission as covariates. RESULTS: Of 178 patients with lobar ICH, 52 (29.2%) had aSAH+FLPs, 60 (33.7%) aSAH only, 1 (0.6%) FLPs, and 65 (36.5%) none. Patients with aSAH+FLPs were older (79.0 ± 9.2 years) than those with only one criterion or none (74.0 ± 15.3 and 72.2 ± 13.8 years, respectively; P = 0.020). Patients with aSAH+FLPs also had more severe ICH at onset, higher in-hospital case-fatality (log rank test P = 0.003) and higher mRS scores at discharge (P < 0.001) as compared to those fulfilling one or none of the Edinburgh criteria. Low Glasgow Coma Scale score was the only factor independently associated to in-hospital case-fatality (odds ratio per point increase 0.51; 95% confidence interval, 0.32-0.91; P = 0.021). DISCUSSION: Our data suggest the applicability of the Edinburgh CT criteria in a hospital setting. The presence of those criteria reflects ICH clinical severity. CONCLUSIONS: Applying the Edinburgh CT criteria might help refining the diagnosis and improving the management of patients with lobar ICH.

Usefulness of administrative databases in identifying the predictive factors of repeated hospitalizations for heart failure.

OBJECTIVES: to investigate heart failure (HF) hospitalizations, the following one-year follow-up, and any possible connection between rehospitalizations due to HF and patients' characteristics derived from administrative databases. DESIGN: retrospective longitudinal design. SETTING AND PARTICIPANTS: the study was conducted analyzing public hospital records of a district in Abruzzo Region (Central Italy), which counts more than 300,000 inhabitants. Patients hospitalized for HF from 01.01.2016 to 31.12.2017 (index event) were included in the study and followed-up for one year. MAIN OUTCOME MEASURES: frequency of repeated hospital admissions, time intervals from the index HF hospitalizations, and causes of readmissions were investigated. RESULTS: a total of 1,587 patients discharged alive after an index hospitalization for HF were included in the study. The mean age of the patients was 79.6 years and the majority of them were females (53.7%). The mean length of stay (LOS) for the index hospitalizations was 8.8 ±6.8 days. During the follow-up period, 336 (21.2%) patients underwent one to four repeated hospitalizations for HF. The first readmission due to HF occurred after a median time of 106.5 days from the index event discharge, and for 20.0% of all cases it occurred within 31 days; 453 patients (28.6%) were readmitted exclusively for other causes, and 67 (4.2%) died out of hospital without any previous HF re-hospitalization. When the outcome was considered as a composite endpoint (out-of-hospital death/HF re-hospitalization), age >=75 (HR 1.737; 95%CI 1.330-2.267), LOS at the index hospitalization >=8 days (HR 1.302; 95%CI 1.066-1.591), and repeated hospitalizations for other causes (HR 1.789; 95%IC 1.465-2.185) were associated with the risk of repeated hospitalizations for HF. CONCLUSIONS: this study shows that about one HF patient out of five experienced at least one re-hospitalization for HF within one year from index hospitalization. In addition to having a longer index hospitalization, these patients were older and frequently suffered from comorbidities which also led to hospitalizations. The results underline the need for a close and careful follow-up after the discharge of old HF patients with multiple pathologies in order to avoid further HF admissions in a short time.

Increased cardiovascular death rates in a COVID-19 low prevalence area.

The province of L'Aquila (Central Italy) was marginally affected by COVID-19 pandemic, but changes in health care seeking behaviors were noticed. The authors retrospectively analyzed de-identified data concerning all-cause and cardiovascular hospitalizations, cardiovascular acute phase treatments, and in-hospital cardiovascular deaths in the province of L'Aquila from January 1 to March 31, in 2020 and 2019. Incidence rate ratios (IRR) comparing 2020 and 2019 for admissions/procedures were calculated through Poisson regression. All-cause and cardiovascular mortality in the examined time windows was also assessed. Less all-cause (IRR 0.85, P < .001) and cardiovascular (IRR 0.73, P < .001) hospitalizations occurred in 2020 than in 2019. Less daily cardiovascular procedures were also performed (IRR: 0.74, P = .009). A disproportionate decrease in the number of procedures was observed in relation to cardiovascular hospitalizations in 2020 (-5.5%, P = .001). Unlike all-cause mortality, more in-hospital cardiovascular deaths occurred in March 2020 compared with March 2019 (+6.8%, P = .048).

From the "real-world evidence" to prevention strategies: health inequalities in immigrants residing in an Italian Local Health Unit.

OBJECTIVES: to assess the health inequalities of immigrants in the Local Health Unit (LHU) n.1 of the Abruzzo Region with a real-world approach. In particular, 4 main categories of hospitalisation (MDC) linked to health risk behaviours and social determinants were analysed. DESIGN: retrospective study on hospital discharge data (HDD). SETTING AND PARTICIPANTS: resident population in the LHU n.1 of the Abruzzo Region between 2010 and 2018. Hospital discharge forms (HDFs) of the hospitals under the administration of the LHU No. 1 of the Abruzzo Region, which includes three geographical areas (Marsica, Peligno-Sangrina, L'Aquila), in the years 2010-2018 were analysed. MAIN OUTCOME MEASURES: crude hospitalisation trends for immigrants and Italians; comparison of standardised hospitalisation rates in the main immigrant communities. RESULTS: overall, 26,570 SDO were analysed. Average age of inpatients was 40 years (±16) and average hospital stay was 4 days (±7). Immigrants showed a lower tendency to hospitalisation than Italians with a decreasing trend from 2010 to 2018, contrary to the Italians. The Romanian population has a hospitalisation risk for alcohol abuse/drugs and induced organic mental disorders about twice as much as the Italian population. Women from Morocco experienced caesarean section with complications about four times more than the Italian women. CONCLUSIONS: the analysis of routine data highlighted excesses of hospitalisation by some causes and birthplaces. A real-world approach can be useful and timely to the implementation of preventive strategies for specific diseases in defined local areas.
