The role of hospital-based vascular access teams and implications for patient safety: a multi-methods study.
The purpose of this study was to examine the roles, functions, and composition of vascular access teams (VATs) related to the use and management of PICC and midline catheters. The researchers administered an online survey of 62 hospitals participating in a quality improvement consortium and qualitative interviews with 74 hospital-based clinicians in 10 sites. The study found that more than 77% of hospitals had an on-site VAT. The average team size was seven nurses; their main function was device insertion. Findings from the interviews revealed variations in team characteristics and functions. Interviewees characterized the broad role that teams play in device insertion, care, and removal, and in educating/training hospital staff. The researchers found that teams' role in decision making, especially related to appropriate device selection, was limited an was met with physician resistance in some cases.

Outcomes associated with sodium-glucose cotransporter-2 inhibitor use in acute heart failure hospitalizations complicated by AKI.
This retrospective study examined the association of sodium-glucose cotransporter-2 inhibitor (SGLT2i) use with patients who have KDIGO-defined acute kidney injury (AKI) during acute heart failure (AHF) hospitalizations and their kidney function recovery at 14 days and 30 days using time-varying multivariable Cox-regression analyses. The study looked at 3305 adults hospitalized across 5 Yale New Haven Health Systems between January 2020 and May 2022 with AHF complicated by KDIGO-defined AKI. Of those individuals hospitalized with AHF and AKI, 356 received SGLT2i following AKI diagnosis either as initiation or continuation. The rate of renal recovery was not significantly different among those exposed and unexposed to SGLT2i following AKI (adjusted HR 0.94). SGLT2i exposure was associated with lower risk of 30-day mortality (adjusted HR 0.45). Rates of renal recovery were similar between the exposed and nonexposed cohorts regardless of the proximity of SGLT2i exposure to AKI diagnosis.

Trends in venous thromboembolism anticoagulation in patients hospitalized with COVID-19.
This study’s objective was to characterize frequency, variation across hospitals, and change over time in VTE prophylaxis and treatment-dose anticoagulation in patients hospitalized for COVID-19, as well as the association of anticoagulation strategies with in-hospital and 60-day mortality. This cohort study used adults hospitalized with COVID-19 from 30 pseudorandom hospitals in Michigan from March 7, 2020, to June 17, 2020. Main outcomes measured were the effect of nonadherence and anticoagulation strategies on in-hospital and 60-day mortality. Of a total 1351 patients with COVID-19 with a median age of 64 years, 47.7% women and 48.9% Black, only 18 (1.3%) had a confirmed VTE, and 219 (16.2%) received treatment-dose anticoagulation. Use of treatment-dose anticoagulation without imaging ranged from 0% to 29% across hospitals and increased over time. Of 1127 patients who ever received anticoagulation, 392 missed 2 or more days of prophylaxis. Missed prophylaxis varied from 11% to 61% across hospitals and decreased markedly over time. VTE nonadherence was associated with higher 60-day (adjusted hazard ratio [aHR], 1.31) but not in-hospital mortality (aHR, 0.97). Receiving any dose of anticoagulation (vs no anticoagulation) was associated with lower in-hospital mortality (only prophylactic dose: aHR, 0.36; any treatment dose: aHR, 0.38). However, only the prophylactic dose of anticoagulation remained associated with lower mortality at 60 days (prophylactic dose: aHR, 0.71; treatment dose: aHR, 0.92).

Patterns in continuous pulse oximetry data prior to pulseless electrical activity arrest in the general care setting.
This study’s objective was to understand if features derived from continuous pulse oximetry data can provide advanced warning of pulseless electrical activity arrest in general care inpatients. A retrospective analysis of SpO2 and pulse rate data derived from continuous pulse oximetry was performed for patients with electrical pulseless activity (n = 38) and control patients (n = 42). The pulseless electrical activity arrest group tended to have lower mean SpO2 and higher mean pulse rates over time intervals ranging from 1 minute to 1 hour. Several hours to the rescue event changes in variability were observed. Up to 20 minutes before rescue events, pulse rate features were significantly different from feature values for the preceding 30-minute interval. Similar results were found at 10 minutes before the event. These differences might be useful for predicting and preventing rescue events.

Comparing two proximal measures of unrecognized clinical deterioration in children.
Critical deterioration events (CDEs) and emergency transfers (ETs) are two proximal measures to cardiopulmonary arrest, and both aim to evaluate how systems recognize and respond to clinical deterioration in children. This retrospective observational study sought to (1) characterize CDEs and ETs by timing, overlap, and intervention category, and (2) evaluate the performance of the watcher identification system and the pediatric early warning score (PEWS) to identify patients who experience these events.

Trends in treatment for patients hospitalized with heart failure with preserved ejection fraction before and after Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT).
This study examined treatment trends for patients hospitalized for heart failure with preserved ejection fraction (HFpEF) after the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT) trial, which investigated spironolactone treatment vs placebo in HFpEF patients. This retrospective analysis looked at discharge prescribing data in the Get With The Guidelines-Heart Failure Registry among patients with left ventricular ejection fraction ≥50% discharged between 2009-2016. About 13% of the cohort of 142,201 patients were prescribed mineralocorticoid receptor antagonists (MRAs) at discharge. MRA prescribing increased modestly over time, but the TOPCAT trial did not seem to have an impact.

Diuretic resistance in heart failure.
Diuretic resistance (DR) occurs along a spectrum of relative severity and contributes to worsening of acute heart failure (AHF) during an inpatient stay. This review gives an overview of mechanisms of DR with a focus on loop diuretics and summarizes the current literature regarding the prognostic value of diuretic efficiency and predictors of natriuretic response in AHF.

Relationship between hospital 30-day mortality rates for heart failure and patterns of early inpatient comfort care.
This study describes the use of early comfort care for patients with heart failure (HF), and whether hospitals that more commonly initiate comfort care have higher 30-day mortality rates. It found that hospital use of early comfort care for HF varies, has not increased over time, and on average, is not correlated with 30-day risk-standardized mortality rates.

Reliability and validity of the patient activation measure in hospitalized patients.
The objectives of this article are to describe the internal consistency reliability and construct validity of the PAM-13 for hospitalized cardiology and oncology patients and to examine the predictors of low patient activation in the same population. The authors found that patients with unplanned admissions were more likely to have low activation than patients with planned admissions. They also found that PAM-13 was modestly correlated with each of the PROMIS Global Health components: global, physical and mental health. They concluded that this study demonstrates the PAM-13 is a reliable and valid measure for use in the inpatient hospital setting and that type of admission is an important predictor of patient activation.

Geographic and facility variation in inpatient stroke rehabilitation: multilevel analysis of functional status.
This study examined geographic and facility variation in cognitive and motor functional outcomes after postacute inpatient rehabilitation in patients with stroke. Its findings suggest that variation in motor and cognitive function at discharge after postacute rehabilitation in patients with stroke is accounted for more by facility than geographic location.

Policies allowing family presence during resuscitation and patterns of care during in-hospital cardiac arrest.
A growing number of hospitals have begun to implement policies allowing for family presence during resuscitation (FPDR). However, the overall safety of these policies and their effect on resuscitation care is unknown. This study suggests that hospitals with an FPDR policy generally have no statistically significant differences in outcomes and processes of care as hospitals without this policy.
