Correlation between continuous Positive end-expiratory pressure (PEEP) values and occurrence of Pneumothorax and Pneumomediastinum in SARS-CoV2 patients during non-invasive ventilation with Helmet

Background: Acute Hypoxemic Respiratory Failure is a common complication of SARS-CoV2 related pneumonia, for which non-invasive ventilation (NIV) with Helmet Continuous Positive Airway Pressure (CPAP) is widely used. The frequency of pneumothorax in SARS-CoV2 was reported in 0.95% of hospitalized patients in 6% of mechanically ventilated patients, and in 1% of a post-mortem case series. Objectives: Aim of our retrospective study was to investigate the incidence of pneumothorax and pneumomediastinum (PNX/PNM) in SARS-CoV2 pneumonia patients treated with Helmet CPAP. Moreover, we examined the correlation between PNX/PNM and Positive end-expiratory pressure (PEEP) values. Methods: We collected data from patients admitted to "Luigi Sacco" University Hospital of Milan from 2 February to 5 May 2020 with SARS-CoV2 pneumonia requiring CPAP. Patients, who need NIV with bi-level pressure or endotracheal intubation (ETI) for any reason except those who needed ETI after PNX/PNM, were excluded. Population was divided in two groups according to PEEP level used (<= 10 cmH2O and >10 cmH2O). Results: 154 patients were enrolled. In the overall population, 42 patients (27%) were treated with High-PEEP (<= 10 cmH2O), and 112 with Low-PEEP (<= 10 cmH20). During hospitalization 3 PNX and 2 PNM occurred (3.2%). Out of these five patients, 2 needed invasive ventilation after PNX and died. All the PNX/PNM occurred in the High-PEEP group (5/37 vs 0/112, p<0,001). Conclusion: The incidence of PNX appears to be lower in SARS-CoV2 than SARS and MERS. Considering the association of PNX/PNM with high PEEP we suggest using the lower PEEP as possible to prevent these complications

Drug prescription appropriateness in hospitalized older patients: 15-year results and lessons from a countrywide register.

The global increase of aging with the related increase of multiple noncommunicable diseases is inevitably accompanied by the associated issue of multimorbidity and polypharmacy. The latter is not without peculiar consequences on health, because it has been shown to be associated with drug-related adverse events, mainly due to poor prescription appropriateness and drug-drug interactions. To contribute to tackle this gigantic problem, a registry of drug dispensation in hospitalized older patient has been initiated in Italy in 2008. Through the last 15 years, data on nearly 11,000 older people have been accrued during their hospital stay in internal medicine and geriatric wards. This review article summarizes the main findings obtained, and how these data contribute to tackle the issue of appropriateness of drug prescription and the need of deprescribing in hospitalized older people affected by the most common noncommunicable diseases

Statins, ACE/ARBs drug use, and risk of pneumonia in hospitalized older patients: a retrospective cohort study

The aims of this study is to evaluate the association between angiotensin-converting enzyme inhibitor (ACE-I), angiotensin II receptor blocker (ARBs) and/or statin use with the risk of pneumonia, as well as and with in-hospital and short-term outpatient mortality in hospitalized older patients with pneumonia. Patients aged 65 years or older hospitalized in internal medicine and/or geriatric wards throughout Italy and enrolled in the REPOSI (REgistro Politerapuie SIMI-Societa Italiana di Medicina Interna) register from 2010 to 2019 were screened to assess the diagnosis of pneumonia and classified on whether or not they were prescribed with at least one drug among ACE-I, ARBs, and/or statins. Further study outcomes were mortality during hospital stay and at 3 months after hospital discharge. Among 5717 cases included (of whom 18.0% with pneumonia), 2915 (51.0%) were prescribed at least one drug among ACE-I, ARBs, and statins. An inverse association was found between treatment with ACE-I or ARBs and pneumonia (OR = 0.79, 95% CI 0.65-0.95). A higher effect was found among patients treated with ACE-I or ARBs in combination with statins (OR = 0.67, 95% CI 0.52-0.85). This study confirmed in the real-world setting that these largely used medications may reduce the risk of pneumonia in older people, who chronically take them for cardiovascular conditions

Proton pump inhibitors and 1-year risk of adverse outcomes after discharge from internal medicine wards: an observational study in the REPOSI cohort.

Proton pump inhibitors are widely prescribed at hospital discharge from internal medicine wards and inappropriate use is common. We retrospectively conducted a survival analysis on data collected from the Registro Politerapie SIMI (REPOSI) registry to evaluate the 1-year risk of hospitalization or mortality associated with the use of PPI, with a particular focus on the appropriateness of use and newly initiated prescriptions at discharge. 7280 patients were discharged from hospital and 4579 (62.9%) had a PPI prescription. The use of PPI was significantly associated with 1-year risk of mortality in the univariate model (hazard ratio (HR) 1.33, p = 0.0012) and also when adjusted for confounders (adjusted HR 1.47, p = 0.0009). In the sensitivity analysis, new PPI prescription use at discharge was associated with an increased risk of mortality (adjusted HR of 1.53, p = 0.006). Inappropriate use was also linked to a nearly 60% higher risk of 1-year mortality and 27% increased risk of 1-year re-hospitalization. Among new PPI users, inappropriate use was associated with nearly 70% increased risk of 1-year mortality (HR 1.69). PPI use was associated with an increased risk of 1-year mortality and re-hospitalization in older adults discharged from hospitals. A higher risk of mortality was observed among new inappropriate PPI users, underscoring the importance of carefully evaluating the unnecessary initiation of new medications at discharge to maintain a favorable benefit-risk ratio.Impact of findings on practice statements. Proton pump inhibitors are among the most commonly prescribed medications. Use of proton pump inhibitors at hospital discharge was associated with a risk of 1-year mortality. Unnecessary PPI use was associated with higher risk of mortality. Patients discharged from internal medicine wards had high rates of inappropriate PPI use. The unnecessary initiation of new drugs at discharge for a favorable benefit-risk ratio was evaluated

Comparison of Anticholinergic Burden Scales and Their Association with Cognitive and Functional Impairment in Older Adults: A Cross-Sectional Study Using the REPOSI Database.

Background: The increasing use of anticholinergic medications in older adults with multiple chronic conditions raises significant concerns regarding their cumulative anticholinergic burden, which is linked to several adverse outcomes. This study aimed to compare existing anticholinergic burden scales to identify those most effective at correlating drug-induced anticholinergic load with cognitive and functional impairment. In addition, we proposed a new classification system on the basis of published scales to optimally correlate total anticholinergic burden with observed clinical deficits. Methods: This cross-sectional study analyzed data from the REPOSI registry, which collects clinical and therapeutic information on patients aged 65 years and older admitted to internal medicine and geriatric wards across Italy. Anticholinergic exposure was assessed using 20 established anticholinergic burden scales from literature. In addition, seven experimental scales were developed on the basis of published scales and various mathematical functions (maximum, mode, median, and mean) to evaluate potential differences in measuring anticholinergic load. Outcomes included cognitive impairment, assessed using the Short Blessed Test (SBT), and functional independence, measured by the Barthel Index (BI). A zero-inflated negative binomial model was applied to analyze associations between anticholinergic burden and each outcome. Given the variability in drug scoring across published scales, we developed seven experimental scales using different mathematical functions (maximum, mode, median, and mean) to standardize scoring. Three versions included a null-score adjustment to account for drugs omitted in some scales, ensuring a more comprehensive measure of anticholinergic burden. Results: Among 7735 patients, higher anticholinergic burden was consistently associated with increased cognitive impairment (SBT) and physical dependency (BI) across all existing and proposed scales. The modified Anticholinergic Risk Scale (mARS) scale showed the strongest associations with cognitive (rate ratio [RR] 1.10, 95% confidence interval [CI] 1.06, 1.13; P < 0.0001) and physical impairment (RR 1.18, 95% CI 1.11, 1.24; P < 0.0001), indicating an 18% higher risk of dependency per unit increase, while the CRIDECO Anticholinergic Load Scale (CALS) scale exhibited the best model fit. Our newly developed scales confirmed these associations, with the median with null score and the mean with null score scale showing the strongest link to cognitive impairment (RR 1.07, 95% CI 1.05, 1.09; P < 0.0001) and the strongest association with physical dependency (RR 1.11, 95% CI 1.08, 1.15; P < 0.0001). Conclusions: Scales that identify a greater proportion of patients with at least one anticholinergic drug may provide a more comprehensive assessment of anticholinergic burden in clinical practice. While no single scale demonstrated a definitive advantage across all outcomes, these scales may identify patients at risk. Prioritizing the use of scales with broader coverage could enhance clinical decision-making and optimize management of polypharmacy in older adults and recognize its potential impact on cognitive and functional outcomes

Statins, ACE/ARBs drug use, and risk of pneumonia in hospitalized older patients: a retrospective cohort study

The aims of this study is to evaluate the association between angiotensin-converting enzyme inhibitor (ACE-I), angiotensin II receptor blocker (ARBs) and/or statin use with the risk of pneumonia, as well as and with in-hospital and short-term outpatient mortality in hospitalized older patients with pneumonia.

Prescription of ACE-Is/ARBs in patients with cardio-renal disease: a multicenter retrospective cohort study from the REPOSI registry

Cardio-renal disease is a common clinical condition leading to increased morbidity and mortality. Angiotensin-converting enzyme inhibitors (ACE-Is) and angiotensin II receptor blockers (ARBs) are the cornerstone of treatment of chronic cardio-renal disease. Using data from the REPOSI register, we performed a multicenter, observational, retrospective study to determine which factors are associated with the non-prescription or discontinuation of ACE-Is/ARBS in a cohort of 889 cardio-renal patients hospitalized in 109 Italian internal medicine and geriatric wards. Only 55% of the patients with cardio-renal disease of the investigated cohort were on treatment with ACE-Is or ARBs at admission. The primary end point was ACE-Is/ARBs use at discharge. Patients with lower probability of receiving ACE-Is/ARBs at discharge were older and hospitalized for longer periods. Furthermore, patients with advanced chronic kidney disease (advanced CKD: eGFR ≤ 29 mL/min/1.73m2) had a much lower (54%) probability of being discharged or continuing ACE-Is/ARBs treatment than those with eGFR ≥ 60 mL/min/1.73m2. A more prominent lower probability was found comparing advanced CKD patients with G3 stage CKD patients (eGFR: 59-30 mL/min/1.73m2) in multivariate analyses (OR and 95%CI: 0.37, 0.24-0.57. multivariate p-value < 0.001). The probability of stopping treatment in patients already on treatment with ACE-Is/ARBs at hospital admission (secondary end point) almost reached a threefold increase (OR and 95%CI: 2.82, 1.69-4.71. multivariate p-value < 0.001) when the advanced CKD group was compared with G3 CKD patients. The data of our study are not in line with the recently published updated KDIGO 2024 Guidelines, which recommend patients with advanced CKD to continue treatment with ACE-Is/ARBs.
