Comparative Effectiveness of Decision Aids for Cancer-Screening Decision Making: An Overview of Reviews.

BACKGROUND: Decision aids (DAs), compared to no DAs, help improve the key aspects of shared decision-making, including increased knowledge, discussion frequency, and reduction in decisional conflict. However, systematic reviews have reported varied conclusions on screening uptake, and which DAs are superior to alternative forms in shared decision-making for cancer screening has not been comprehensively reviewed. METHODS: An overview of systematic reviews was performed. Multiple databases were searched up to December 31, 2023, for systematic reviews of randomized controlled trials (RCTs) and non-randomized comparative studies (NRCSs) of any size that assessed a decision aid aimed to facilitate cancer-screening decision making communications. Dual screening of abstracts and full-text reports, dual data extraction and quality assessment, and qualitative synthesis were performed. RESULTS: The 22 eligible publications included 24 reviews on cancer screening DAs for a single specific cancer (8, 8, 7, and 1 on prostate, breast, colorectal, and lung cancer, respectively) and three reviews on multiple aggregate cancers. Individual reviews were based on different primary study designs (92 RCTs and 37 NRCSs); each study was infrequently cited (median citation count 2; range 1-9). Although the DAs had variable formats and delivery methods, the reviews generally focused on use and non-use comparisons. DAs decreased the intention or actual uptake for prostate and breast cancer screening, but increased it for colorectal cancer screening. DAs were associated with increased knowledge, well-informed choice, and reduced decisional conflict, regardless of cancer type. Only four reviews on comparative effectiveness between alternative formats of DAs (based on 14 RCTs and 2 NRCSs) failed to conclude on the specific format that was superior to others. DISCUSSION: DAs improve cancer screening shared decision-making by boosting cancer screening knowledge and informed choice and lowering decisional conflict and may facilitate preference-based, individualized screening participation. Comparative data on different cancer screening DAs are limited. SYSTEMATIC REVIEW REGISTRATION: PROSPERO, CRD42021235957.

External validation and update of the International Medical Prevention Registry on Venous Thromboembolism bleeding risk score for predicting bleeding in acutely ill hospitalized medical patients: a retrospective single-center cohort study in Japan.

BACKGROUND: The International Medical Prevention Registry for Venous Thromboembolism (IMPROVE) Bleeding Risk Score is the recommended risk assessment model (RAM) for predicting bleeding risk in acutely ill medical inpatients in Western countries. However, few studies have assessed its predictive performance in local Asian settings. METHODS: We retrospectively identified acutely ill adolescents and adults (aged ≥ 15 years) who were admitted to our general internal medicine department between July 5, 2016 and July 5, 2021, and extracted data from their electronic medical records. The outcome of interest was the cumulative incidence of major and nonmajor but clinically relevant bleeding 14 days after admission. For the two-risk-group model, we estimated sensitivity, specificity, and positive and negative predictive values (PPV and NPV, respectively). For the 11-risk-group model, we estimated C statistic, expected and observed event ratio (E/O), calibration-in-the-large (CITL), and calibration slope. In addition, we recalibrated the intercept using local data to update the RAM. RESULTS: Among the 3,876 included patients, 998 (26%) were aged ≥ 85 years, while 656 (17%) were hospitalized in the intensive care unit. The median length of hospital stay was 14 days. Clinically relevant bleeding occurred in 58 patients (1.5%), 49 (1.3%) of whom experienced major bleeding. Sensitivity, specificity, NPV, and PPV were 26.1% (95% confidence interval [CI]: 15.8-40.0%), 84.8% (83.6-85.9%), 98.7% (98.2-99.0%), and 2.5% (1.5-4.3%) for any bleeding and 30.9% (95% CI: 18.8-46.3%), 84.9% (83.7-86.0%), 99.0% (98.5-99.3%), and 2.5% (1.5-4.3%) for major bleeding, respectively. The C statistic, E/O, CITL, and calibration slope were 0.64 (95% CI: 0.58-0.71), 1.69 (1.45-2.05), - 0.55 (- 0.81 to - 0.29), and 0.58 (0.29-0.87) for any bleeding and 0.67 (95% CI: 0.60-0.74), 0.76 (0.61-0.87), 0.29 (0.00-0.58), and 0.42 (0.19-0.64) for major bleeding, respectively. Updating the model substantially corrected the poor calibration observed. CONCLUSIONS: In our Japanese cohort, the IMPROVE bleeding RAM retained the reported moderate discriminative performance. Model recalibration substantially improved the poor calibration obtained using the original RAM. Before its introduction into clinical practice, the updated RAM needs further validation studies and an optimized threshold.

Association between intrarenal venous flow from Doppler ultrasonography and acute kidney injury in patients with sepsis in critical care: a prospective, exploratory observational study.

BACKGROUND: Intrarenal venous flow (IRVF) patterns assessed using Doppler renal ultrasonography are real-time bedside visualizations of renal vein hemodynamics. Although this technique has the potential to detect renal congestion during sepsis resuscitation, there have been few studies on this method. We aimed to examine the relationship between IRVF patterns, clinical parameters, and outcomes in critically ill adult patients with sepsis. We hypothesized that discontinuous IRVF was associated with elevated central venous pressure (CVP) and subsequent acute kidney injury (AKI) or death. METHODS: We conducted a prospective observational study in two tertiary-care hospitals, enrolling adult patients with sepsis who stayed in the intensive care unit for at least 24 h, had central venous catheters placed, and received invasive mechanical ventilation. Renal ultrasonography was performed at a single time point at the bedside after sepsis resuscitation, and IRVF patterns (discontinuous vs. continuous) were confirmed by a blinded assessor. The primary outcome was CVP obtained at the time of renal ultrasonography. We also repeatedly assessed a composite of Kidney Disease Improving Global Outcomes of Stage 3 AKI or death over the course of a week as a secondary outcome. The association of IRVF patterns with CVP was examined using Student's t-test (primary analysis) and that with composite outcomes was assessed using a generalized estimating equation analysis, to account for intra-individual correlations. A sample size of 32 was set in order to detect a 5-mmHg difference in CVP between IRVF patterns. RESULTS: Of the 38 patients who met the eligibility criteria, 22 (57.9%) showed discontinuous IRVF patterns that suggested blunted renal venous flow. IRVF patterns were not associated with CVP (discontinuous flow group: mean 9.24 cm H2O [standard deviation: 3.19], continuous flow group: 10.65 cm H2O [standard deviation: 2.53], p = 0.154). By contrast, the composite outcome incidence was significantly higher in the discontinuous IRVF pattern group (odds ratio: 9.67; 95% confidence interval: 2.13-44.03, p = 0.003). CONCLUSIONS: IRVF patterns were not associated with CVP but were associated with subsequent AKI in critically ill adult patients with sepsis. IRVF may be useful for capturing renal congestion at the bedside that is related to clinical patient outcomes.

An early return-to-work program for COVID-19 close contacts in healthcare during the Omicron wave in Japan.

During the coronavirus disease 2019 (COVID-19) pandemic, maintaining adequate staffing in healthcare facilities is important to provide a safe work environment for healthcare workers (HCWs). Japan's early return-to-work (RTW) program may be a rational strategy at a time when there is an increased demand for the services of HCWs. We assessed whether the early RTW program for HCWs who have been in close contact with a COVID-19 case in our hospital was justified. Close contacts were identified according to the guidance document of the World Health Organization. HCWs who met all of the following conditions were eligible to apply to an early RTW program: (1) difficult to replace with another HCW, (2) received the third dose of a COVID-19 mRNA vaccine, (3) a negative COVID-19 antigen test before each work shift, and (4) consent from relevant HCWs and their managers to participate in the program. Between January and March 2022, 256 HCWs were identified as close contacts (median age, 35 years; 192 female). Thirty-seven (14%) secondary attack cases of COVID-19 were detected. Among 141 HCWs (55%) who applied to the early RTW program, nurses and physicians comprised about three-quarters of participants, with a higher participation rate by physicians (78%) than nurses (59%). Eighteen HCWs tested positive for COVID-19 by the sixth day after starting the early RTW program. No COVID-19 infection clusters were reported during the observation period. These findings suggest that the early RTW program for COVID-19 close contacts was a reasonable strategy for HCWs during the Omicron wave.

Short-course remdesivir for healthcare-associated COVID-19: Case series from a non-acute care hospital.

Healthcare-associated COVID-19 among vulnerable patients leads to disproportionate morbidity and mortality. Early pharmacologic intervention may reduce negative sequelae and improve survival in such settings. This study aimed to describe outcome of patients with healthcare-associated COVID-19 who received early short-course remdesivir therapy. We reviewed the characteristics and outcome of hospitalized patients who developed COVID-19 during an outbreak that involved two wards at a non-acute care hospital in Japan and received short-course remdesivir. Forty-nine patients were diagnosed with COVID-19, 34 on a comprehensive inpatient rehabilitation ward and 15 on a combined palliative care and internal medicine ward. Forty-seven were symptomatic and 46 of them received remdesivir. The median age was 75, and the median Charlson comorbidity index was 6 among those who received it. Forty-one patients had received one or two doses of mRNA vaccines, while none had received a third dose. Most patients received 3 days of remdesivir. Of the patients followed up to 14 and 28 days from onset, 41/44 (95.3%) and 35/41(85.4%) were alive, respectively. Six deaths occurred by 28 days in the palliative care/internal medicine ward and two of them were possibly related to COVID-19. Among those who survived, the performance status was unchanged between the time of onset and at 28 days.

Lung Pathology of Mutually Exclusive Co-infection with SARS-CoV-2 and Streptococcus pneumoniae.

Postmortem lung pathology of a patient in Japan with severe acute respiratory syndrome coronavirus 2 infection showed diffuse alveolar damage as well as bronchopneumonia caused by Streptococcus pneumoniae infection. The distribution of each pathogen and the accompanying histopathology suggested the infections progressed in a mutually exclusive manner within the lung, resulting in fatal respiratory failure.

Predictors of Diagnostic Contributions and Spontaneous Remission of Symptoms Associated with Positron Emission Tomography with Fluorine-18-Fluorodeoxy Glucose Combined with Computed Tomography in Classic Fever or Inflammation of Unknown Origin: a Retrospective Study.

BACKGROUND: In patients with fever or inflammation of unknown origin (fever of unknown origin [FUO] or inflammation of unknown origin [IUO], respectively), expert consensus recommends the use of positron emission tomography with fluorine-18-fluorodeoxy glucose combined with computed tomography (FDG-PET/CT) when standard work-up fails to identify diagnostic clues. However, the clinical variables associated with successful localization of the cause by FDG-PET/CT remain uncertain. Moreover, the long-term outcomes of patients with unexplained FUO or IUO after negative FDG-PET/CT results are unknown. Therefore, we assessed predictors of successful diagnosis of FUO or IUO caused by FDG-PET/CT and associations of spontaneous remission of symptoms with FDG-PET/CT results. METHODS: All patients with FUO or IUO, who underwent FDG-PET/CT from 2013 to 2019 because diagnostic work-up failed to identify a cause, were retrospectively included. We calculated the diagnostic yield and performed multivariable logistic regression to assess characteristics previously proposed to be associated with successful localization of FUO or IUO causes. We also assessed whether the FDG-PET/CT results were associated with spontaneous remissions. RESULTS: In total, 50 patients with diagnostically challenging FUO or IUO (35 with FUO and 15 with IUO) were assessed. Other than one case of infection, all the identified causes were either malignancy or non-infectious inflammatory diseases (each with 18 patients), and FDG-PET/CT correctly localized the cause in 29 patients (diagnostic yield = 58%). None of the proposed variables was associated with successful localization. All 13 patients with sustained unexplained cause remained alive (median follow-up, 190 days). Spontaneous remission was observed in 4 of 5 patients with a negative FDG-PET/CT, and 1 of 8 with a positive result (P = 0.018). CONCLUSION: In the current cohort, the proposed variables were not predictive for successful localization by FDG-PET/CT. A negative FDG-PET/CT scan may be prognostic for spontaneous remission in patients with sustained FUO or IUO.

Sputum Gram Stain for Bacterial Pathogen Diagnosis in Community-acquired Pneumonia: A Systematic Review and Bayesian Meta-analysis of Diagnostic Accuracy and Yield.

BACKGROUND: The clinical role of sputum Gram stain (SGS) in community-acquired pneumonia (CAP) diagnosis remains controversial. A 1996 meta-analysis of the diagnostic accuracy of SGS reported heterogeneous results. To update the available evidence, we performed a systematic review and a Bayesian standard and latent-class model meta-analysis. METHODS: We searched Medline, Embase, and Cochrane Central by 23 August 2018 to identify studies reporting on the diagnostic accuracy, yield (percentage of patients with any pathogen[s] correctly identified by SGS), and clinical outcomes of SGS in adult patients with CAP. Two reviewers extracted the data. We quantitatively synthesized the diagnostic accuracy and yield, and descriptively analyzed other outcomes. RESULTS: Twenty-four studies with 4533 patients were included. The methodological and reporting quality of the included studies was limited. When good-quality sputum specimens were selected, SGS had a summary sensitivity of 0.69 (95% credible interval [CrI], .56-.80) and specificity of 0.91 (CrI, .83-.96) for detecting Streptococcus pneumoniae, and a sensitivity of 0.76 (CrI, .60-.87) and specificity of 0.97 (CrI, .91-.99) for Haemophilus influenzae. Adjusted analyses accounting for imperfect reference standards provided higher-specificity estimates than the unadjusted analyses. Bacterial pathogens were identified in 73% (CrI, 26%-96%) of good-quality specimens, and 36% (CrI, 22%-53%) of all specimens regardless of quality. Evidence on other bacteria was sparse. CONCLUSIONS: SGS was highly specific to diagnose S. pneumoniae and H. influenzae infections in patients with CAP. With good-quality specimens, SGS can provide clinically actionable information for pathogen-directed antibiotic therapies.

A Prospective, Randomized, Open-Label Trial of Early versus Late Favipiravir Therapy in Hospitalized Patients with COVID-19.

Favipiravir is an oral broad-spectrum inhibitor of viral RNA-dependent RNA polymerase that is approved for treatment of influenza in Japan. We conducted a prospective, randomized, open-label, multicenter trial of favipiravir for the treatment of COVID-19 at 25 hospitals across Japan. Eligible patients were adolescents and adults admitted with COVID-19 who were asymptomatic or mildly ill and had an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1. Patients were randomly assigned at a 1:1 ratio to early or late favipiravir therapy (in the latter case, the same regimen starting on day 6 instead of day 1). The primary endpoint was viral clearance by day 6. The secondary endpoint was change in viral load by day 6. Exploratory endpoints included time to defervescence and resolution of symptoms. Eighty-nine patients were enrolled, of whom 69 were virologically evaluable. Viral clearance occurred within 6 days in 66.7% and 56.1% of the early and late treatment groups (adjusted hazard ratio [aHR], 1.42; 95% confidence interval [95% CI], 0.76 to 2.62). Of 30 patients who had a fever (≥37.5°C) on day 1, times to defervescence were 2.1 days and 3.2 days in the early and late treatment groups (aHR, 1.88; 95% CI, 0.81 to 4.35). During therapy, 84.1% developed transient hyperuricemia. Favipiravir did not significantly improve viral clearance as measured by reverse transcription-PCR (RT-PCR) by day 6 but was associated with numerical reduction in time to defervescence. Neither disease progression nor death occurred in any of the patients in either treatment group during the 28-day participation. (This study has been registered with the Japan Registry of Clinical Trials under number jRCTs041190120.).

Effect of continuation of antiplatelet therapy on survival in patients receiving physician home visits.

BACKGROUND: Little is known about the effects of continued antiplatelet therapy in patients who receive physician home visits. This study aimed to evaluate the association of survival with the continuation of antiplatelet drugs in patients who received physician home visits. METHODS: A retrospective cohort study was conducted in a teaching hospital in Toyota, Japan, from April 2015 to October 2018. All patients who received home visits by physicians from the department of Family Medicine of the hospital were included. The primary outcome was the difference in all-cause mortality between patients who were taking antiplatelet drugs and those who were not. The Cox proportional hazards model was applied, adjusted for the patient's demographic features, activities of daily living, comorbidities, and primary disease requiring home care. RESULTS: A total of 815 patients were included, of whom 61 received antiplatelet drugs (n = 42 for aspirin, n = 17 for clopidogrel, and n = 8 for cilostazol) and 772 received no antiplatelet drugs. The mean age of the patients was 78.3 years, 409 (49.1%) were male, and 314 (37.7%) had end-stage cancer. During a median follow-up period of 120 days (interquartile range, 29-364), 54.3% of the patients died. Compared with patients not taking antiplatelet drugs, patients taking antiplatelet drugs had a better outcome (p <  0.01, log-rank test) and a significantly lower hazard ratio (0.34; 95% confidence interval, 0.17-0.65; Cox proportional hazards regression). CONCLUSIONS: The continuous prescription of antiplatelet drugs may have beneficial effects on mortality among patients who receive physician home visits.

Clinical features of patients with infective endocarditis presenting to the emergency department: a retrospective case series.

Infective endocarditis (IE) is an uncommon clinical problem with diverse, nonspecific presentations. Therefore, information on the clinical features of IE patients presenting to emergency departments (EDs) is scarce. To descriptively analyze the pertinent data, we performed a retrospective chart review. We reviewed 15 consecutive IE patients admitted directly from ED in a university hospital in Japan between 2013 and 2015. We compared their clinical features with those of 14 IE patients admitted during the same period without ED presentations. Patients admitted directly from ED were older than those without ED presentations (median, 78 vs. 52 years; adjusted p = 0.036) and were more likely to have come without referrals (referral rate, 21% vs. 86%; adjusted p = 0.012). These patients were less likely to have been treated with antibiotics before admission (antibiotic-exposure rate, 7% vs. 64%; adjusted p = 0.013) and had earlier blood-culture positivity (median, 2 vs. 5 days; adjusted p = 0.012), resulting in earlier diagnosis (median duration of symptoms before diagnosis, 5 vs. 30 days; adjusted p = 0.012). Other clinical features, including causative pathogens and IE-related comorbidities, were similar between the groups, consistent with previous a nationwide Japanese study. In conclusion, most IE patients admitted to the hospital from ED were elderly, were antibiotic-naïve, and had presented without a referral. Relatively few patients had classical presentations of IE. Given the limited data, more research is needed to confirm that IE patients presenting to EDs constitute a unique group of elderly patients with specific clinical features.

Probiotics-related Clostridium butyricum bacteraemia after COVID-19, confirmed by whole-genome sequencing.

A man in his 70s was admitted to an intensive care unit with severe COVID-19 and treated with dexamethasone and tocilizumab. After recovery from COVID-19, he developed Clostridium butyricum bacteraemia and non-occlusive mesenteric ischaemia, with fatal outcome. He had been prescribed C. butyricum MIYAIRI 588 fine granules as probiotics for a month. The genome sequences of the C. butyricum isolate from the blood culture and C. butyricum MIYAIRI 588 fine granules were identical by single nucleotide polymorphism analysis. This is the first case of definitive probiotics-related C. butyricum bacteraemia after treatment of severe COVID-19.

Polypharmacy of Older Surgical Patients With Extremity Fractures.

Introduction: Fractures are often caused by falls in older people. Among various causes of falls, polypharmacy is known to be a risk of falls. Furthermore, potentially inappropriate medicines (PIMs), which interact with polypharmacy, include the drugs involved in falls. Here, we primarily aimed to investigate the prescribed drugs in older surgical patients with extremity fractures to determine the frequency of polypharmacy and identify PIMs. The second aim was to clarify the characterization of prescribed drugs of older patients with hip fracture. Materials and Methods: We retrospectively collected the following clinical data of consecutive patients aged ≥65 years who underwent surgery for extremity fractures at our hospital between April 2019 and March 2021. A total of 19 categories were considered as PIMs. The Poisson regression models were used to examine the association between the number of prescribed drugs and hip fracture prevalence. Results: A total of 590 patients were reviewed. Our data showed that 55% of older patients with extremity fractures took ≥6 prescription drugs. The frequency of prescription of hypnotics, antithrombotic drugs, diuretics, and non-steroidal anti-inflammatory drugs was comparatively high among the 19 categories of PIMs. Multivariable analysis revealed that polypharmacy was significantly associated with hip fractures. Among PIMs, antithrombotic drugs and diuretics were significantly associated with the prevalence of hip fractures. Finally, we found a significant positive association between the prevalence of hip fracture and the number of drug categories of PIMs among older patients with extremity fractures. Conclusions: The present study clarified the characterization of the prescribed drugs in older surgical patients with extremity fractures. Special attention should be paid to hip fractures of older patients with polypharmacy or prescribed with many drugs categories of PIMs, particularly antithrombotic drugs and diuretics.

External Validation of the Padua and IMPROVE-VTE Risk Assessment Models for Predicting Venous Thromboembolism in Hospitalized Adult Medical Patients: A Retrospective Single-Center Study in Japan.

Objectives: To assess the external validity of the Padua and International Medical Prevention Registry on Venous Thromboembolism (IMPROVE-VTE) risk assessment models (RAMs) for predicting venous thromboembolism (VTE) within 90 days of admission among hospitalized medical patients in Japan. Materials and Methods: A university hospital cohort comprising 3876 consecutive patients ages ≥15 years admitted to a general internal medicine department between July 2016 and July 2021 was retrospectively analyzed using data extracted from their medical records. Results: A total of 74 VTE events (1.9%), including six cases with pulmonary embolism (0.2%), were observed. Both RAMs had poor discriminative performance (C-index=0.64 for both) and generally underestimated VTE risks. However, recalibrating the IMPROVE-VTE RAM to update the baseline hazard improved the calibration (calibration slope=1.01). Decision curve analysis showed that a management strategy with no prediction model outperformed a clinical management strategy guided by the originally proposed RAMs. Conclusions: Both RAMs require an update to function in this particular setting. Further studies with a larger-sized cohort, including re-estimation of the individual regression coefficients with additional, more context-specific predictors, are needed to create a useful model that would help advance risk-oriented VTE prevention programs.

External validation of the Michigan PICC catheter-associated bloodstream infections score (MPC score) for predicting the risk of peripherally inserted central catheter-associated bloodstream infections: A single-center study in Japan.

The Michigan peripherally inserted central catheter-associated bloodstream infection score (MPC score) had been developed for hospitalized medical patients but had not been externally validated. A retrospective analysis of a clinically heterogeneous case-mix in a university hospital cohort in Japan failed to validate its originally reported good performance.

Radiographic and endoscopic screening to reduce gastric cancer mortality: a systematic review and meta-analysis.

Background: Previous systematic reviews naïvely combined biased effects of screening radiography or endoscopy observed in studies with various designs. We aimed to synthesize currently available comparative data on gastric cancer mortality in healthy, asymptomatic adults by explicitly classifying the screening effects through study designs and types of intervention effects. Methods: We searched multiple databases through October 31, 2022 for this systematic review and meta-analysis. Studies of any design that compared gastric cancer mortality among radiographic or endoscopic screening and no screening in a community-dwelling adult population were included. The method included a duplicate assessment of eligibility, double extraction of summary data, and validity assessment using the Risk Of Bias In Non-randomized Studies of Interventions tool. Bayesian three-level hierarchical random-effects meta-analysis synthesized data corrected for self-selection bias on the relative risk (RR) for per-protocol (PP) and intention-to-screen (ITS) effects. The study registration number at PROSPERO is CRD42021277126. Findings: We included seven studies in which a screening program was newly introduced (median attendance rate, 31%; at moderate-to-critical risk of bias), and seven cohort and eight case-control studies with ongoing screening programs (median attendance rate, 21%; all at critical risk of bias); thus, data of 1,667,117 subjects were included. For the PP effect, the average risk reduction was significant for endoscopy (RR 0.52; 95% credible interval: 0.39-0.79) but nonsignificant for radiography (0.80; 0.60-1.06). The ITS effect was not significant for both radiography (0.98; 0.86-1.09) and endoscopy (0.94; 0.71-1.28). The magnitude of the effects depended on the assumptions for the self-selection bias correction. Restricting the scope to East Asian studies only did not change the results. Interpretation: In limited-quality observational evidence from high-prevalence regions, screening reduced gastric cancer mortality; however, the effects diminished at a program level.

The effect of introducing a nurse-practitioner-led peripherally inserted central venous catheter placement program on the utilization of central venous access device: A retrospective study in Japan.

BACKGROUND: Nurse-led peripherally inserted central venous catheter (PICC) placement teams are common in western hospitals, but they are still in their infancy in Japan. Although implementing a dedicated program may improve ongoing vascular-access management, the direct hospital-level effects of launching a nurse-led PICC team on specific outcomes have not been formally investigated. OBJECTIVES: To evaluate the effect of introducing a nurse practitioner (NP)-led PICC-placement program on subsequent utilization of centrally inserted central catheters (CICCs) and to contrast the quality of PICC placements conducted by physicians and NPs. MATERIALS AND METHODS: Patients who underwent central venous access devices (CVADs) between 2014 and 2020 at a university hospital in Japan were evaluated retrospectively using an interrupted time-series analysis on the trend for monthly CVAD utilization and logistic regression and propensity score-based analyses for PICC-related complications. RESULTS: Among 6007 CVAD placements, 2230 PICCs were inserted into 1658 patients (725 by physicians and 1505 by NPs). The monthly number of CICC utilization fell from 58 in April 2014 to 38 in March 2020, while PICC placements by the NP PICC team increased from 0 to 104. The implementation of the NP PICC program reduced the immediate rate (by 35.5; 95% confidence interval [CI]: 24.1-46.9; p < 0.001) and post-intervention trend (by 2.3; 95% CI: 1.1-3.5; p < 0.001) of monthly CICC utilization. Overall immediate complication rates were lower in the NP group than the physician group (1.5% vs 5.1%; adjusted odds ratio = 0.31; 95% CI: 0.17-0.59; p < 0.001). The cumulative incidences of central line-associated bloodstream infections were comparable between the NP and physician groups (5.9% vs 7.2%; adjusted hazard ratio = 0.96; 95% CI: 0.53-1.75; p = .90). CONCLUSIONS: This NP-led PICC program reduced CICC utilization without affecting the quality of PICC placement or complication rate.

Discontinuation of admission screening for coronavirus disease 2019 (COVID-19) and the impact on in-hospital clusters of COVID-19: Experience at a tertiary-care center.

We evaluated the impact of discontinuing universal preadmission screening for severe acute respiratory coronavirus virus 2 (SARS-CoV-2) on the occurrence of nosocomial clusters of coronavirus disease 2019 (COVID-19) during the SARS-CoV-2 o (omicron) variant period. No increasing trend in nosocomial clusters was observed during community-based surges before and after discontinuation. This finding supports the safety of the practice change.
