Effect of Complementary Interventions to Redesign Care on Teamwork and Quality for Hospitalized Medical Patients: A Pragmatic Controlled Trial: Annals of Internal Medicine: Vol 176, No 11

Background: Multiple challenges impede interprofessional teamwork and the provision of high-quality care to hospitalized patients. Objective: To evaluate the effect of interventions to redesign hospital care delivery on teamwork and patient outcomes. Design: Pragmatic controlled trial. Hospitals selected 1 unit for implementation of interventions and a second to serve as a control. (ClinicalTrials.gov: NCT03745677) Setting: Medical units at 4 U.S. hospitals. Participants: Health care professionals and hospitalized medical patients. Intervention: Mentored implementation of unit-based physician teams, unit nurse–physician coleadership, enhanced interprofessional rounds, unit-level performance reports, and patient engagement activities. Measurements: Primary outcomes were teamwork climate among health care professionals and adverse events experienced by patients. Secondary outcomes were length of stay (LOS), 30-day readmissions, and patient experience. Difference-in-differences (DID) analyses of patient outcomes compared intervention versus control units before and after implementation of interventions. Results: Among 155 professionals who completed pre- and postintervention surveys, the median teamwork climate score was higher after than before the intervention only for nurses (n = 77) (median score, 88.0 [IQR, 77.0 to 91.0] vs. 80.0 [IQR, 70.0 to 89.0]; P = 0.022). Among 3773 patients, a greater percentage had at least 1 adverse event after compared with before the intervention on control units (change, 1.61 percentage points [95% CI, 0.01 to 3.22 percentage points]). A similar percentage of patients had at least 1 adverse event after compared with before the intervention on intervention units (change, 0.43 percentage point [CI, −1.25 to 2.12 percentage points]). A DID analysis of adverse events did not show a significant difference in change (adjusted DID, −0.92 percentage point [CI, −2.49 to 0.64 percentage point]; P = 0.25). Similarly, there were no differences in LOS, readmissions, or patient experience. Limitation: Adverse events occurred less frequently than anticipated, limiting statistical power. Conclusion: Despite improved teamwork climate among nurses, interventions to redesign care for hospitalized patients were not associated with improved patient outcomes.

Implications of the Use of Artificial Intelligence Predictive Models in Health Care Settings: A Simulation Study: Annals of Internal Medicine: Vol 176, No 10

Background: Substantial effort has been directed toward demonstrating uses of predictive models in health care. However, implementation of these models into clinical practice may influence patient outcomes, which in turn are captured in electronic health record data. As a result, deployed models may affect the predictive ability of current and future models. Objective: To estimate changes in predictive model performance with use through 3 common scenarios: model retraining, sequentially implementing 1 model after another, and intervening in response to a model when 2 are simultaneously implemented. Design: Simulation of model implementation and use in critical care settings at various levels of intervention effectiveness and clinician adherence. Models were either trained or retrained after simulated implementation. Setting: Admissions to the intensive care unit (ICU) at Mount Sinai Health System (New York, New York) and Beth Israel Deaconess Medical Center (Boston, Massachusetts). Patients: 130 000 critical care admissions across both health systems. Intervention: Across 3 scenarios, interventions were simulated at varying levels of clinician adherence and effectiveness. Measurements: Statistical measures of performance, including threshold-independent (area under the curve) and threshold-dependent measures. Results: At fixed 90% sensitivity, in scenario 1 a mortality prediction model lost 9% to 39% specificity after retraining once and in scenario 2 a mortality prediction model lost 8% to 15% specificity when created after the implementation of an acute kidney injury (AKI) prediction model; in scenario 3, models for AKI and mortality prediction implemented simultaneously, each led to reduced effective accuracy of the other by 1% to 28%. Limitations: In real-world practice, the effectiveness of and adherence to model-based recommendations are rarely known in advance. Only binary classifiers for tabular ICU admissions data were simulated. Conclusion: In simulated ICU settings, a universally effective model-updating approach for maintaining model performance does not seem to exist. Model use may have to be recorded to maintain viability of predictive modeling. Primary Funding Source: National Center for Advancing Translational Sciences.

Risk for Congenital Anomalies in Children Conceived With Medically Assisted Fertility Treatment: A Population-Based Cohort Study: Annals of Internal Medicine: Vol 176, No 10

Background: More than 2 million children are conceived annually using assisted reproductive technologies (ARTs), with a similar number conceived using ovulation induction and intrauterine insemination (OI/IUI). Previous studies suggest that ART-conceived children are at increased risk for congenital anomalies (CAs). However, the role of underlying infertility in this risk remains unclear, and ART clinical and laboratory practices have changed drastically over time, particularly there has been an increase in intracytoplasmic sperm injection (ICSI) and cryopreservation. Objective: To investigate the role of underlying infertility and fertility treatment on CA risks in the first 2 years of life. Design: Propensity score–weighted population-based cohort study. Setting: New South Wales, Australia. Participants: 851 984 infants (828 099 singletons and 23 885 plural children) delivered between 2009 and 2017. Measurements: Adjusted risk difference (aRD) in CAs of infants conceived through fertility treatment compared with 2 naturally conceived (NC) control groups—those with and without a parental history of infertility (NC-infertile and NC-fertile). Results: The overall incidence of CAs was 459 per 10 000 singleton births and 757 per 10 000 plural births. Compared with NC-fertile singleton control infants (n = 747 018), ART-conceived singleton infants (n = 31 256) had an elevated risk for major genitourinary abnormalities (aRD, 19.0 cases per 10 000 births [95% CI, 2.3 to 35.6]); the risk remained unchanged (aRD, 22 cases per 10 000 births [CI, 4.6 to 39.4]) when compared with NC-infertile singleton control infants (n = 36 251) (that is, after accounting for parental infertility), indicating that ART remained an independent risk. After accounting for parental infertility, ICSI in couples without male infertility was associated with an increased risk for major genitourinary abnormalities (aRD, 47.8 cases per 10 000 singleton births [CI, 12.6 to 83.1]). There was some suggestion of increased risk for CAs after fresh embryo transfer, although estimates were imprecise and inconsistent. There were no increased risks for CAs among OI/IUI-conceived infants (n = 13 574). Limitations: This study measured the risk for CAs only in those children who were born at or after 20 weeks' gestation. Observational study design precludes causal inference. Many estimates were imprecise. Conclusion: Patients should be counseled on the small increased risk for genitourinary abnormalities after ART, particularly after ICSI, which should be avoided in couples without problems of male infertility.

Inappropriate Prescribing to Older Patients by Nurse Practitioners and Primary Care Physicians

Background: Many U.S. states have legislated to allow nurse practitioners (NPs) to independently prescribe drugs. Critics contend that these moves will adversely affect quality of care. Objective: To compare rates of inappropriate prescribing among NPs and primary care physicians. Design: Rates of inappropriate prescribing were calculated and compared for 23 669 NPs and 50 060 primary care physicians who wrote prescriptions for 100 or more patients per year, with adjustment for practice experience, patient volume and risk, clinical setting, year, and state. Setting: 29 states that had granted NPs prescriptive authority by 2019. Patients: Medicare Part D beneficiaries aged 65 years or older in 2013 to 2019. Measurements: Inappropriate prescriptions, defined as drugs that typically should not be prescribed for adults aged 65 years or older, according to the American Geriatrics Society’s Beers Criteria. Results: Mean rates of inappropriate prescribing by NPs and primary care physicians were virtually identical (adjusted odds ratio, 0.99 [95% CI, 0.97 to 1.01]; crude rates, 1.63 vs. 1.69 per 100 prescriptions; adjusted rates, 1.66 vs. 1.68). However, NPs were overrepresented among clinicians with the highest and lowest rates of inappropriate prescribing. For both types of practitioners, discrepancies in inappropriate prescribing rates across states tended to be larger than discrepancies between these practitioners within states. Limitation: The Beers Criteria addresses the appropriateness of a selected subset of drugs and may not be valid in some clinical settings. Conclusion: Nurse practitioners were no more likely than physicians to prescribe inappropriately to older patients. Broad efforts to improve the performance of all clinicians who prescribe may be more effective than limiting independent prescriptive authority to physicians.

Universal Masking in Health Care Settings: A Pandemic Strategy Whose Time Has Come and Gone, For Now

Demonstration Project of Long-Acting Antiretroviral Therapy in a Diverse Population of People With HIV

Background: Intramuscular cabotegravir (CAB) and rilpivirine (RPV) is the only long-acting antiretroviral therapy (LA-ART) regimen approved for people with HIV (PWH). Long-acting ART holds promise for improving outcomes among populations with barriers to adherence but is only approved for PWH who have virologic suppression with use of oral ART before initiating injectables. Objective: To examine LA-ART in a population of PWH that includes those with viremia. Design: Observational cohort study. Setting: Urban academic safety-net HIV clinic. Patients: Publicly insured adults living with HIV with and without viral suppression, high rates of unstable housing, mental illness, and substance use. Intervention: Demonstration project of long-acting injectable CAB–RPV. Measurements: Descriptive statistics summarizing cohort outcomes to date, based on pharmacy team logs and electronic medical record data. Results: Between June 2021 and November 2022, 133 PWH at the Ward 86 HIV Clinic were started on LA-ART, 76 of whom had virologic suppression while using oral ART and 57 of whom had viremia. The median age was 46 years (IQR, 25 to 68 years); 117 (88%) were cisgender men, 83 (62%) had non-White race, 56 (42%) were experiencing unstable housing or homelessness, and 45 (34%) had substance use. Among those with virologic suppression, 100% (95% CI, 94% to 100%) maintained suppression. Among PWH with viremia, at a median of 33 days, 54 of 57 had viral suppression, 1 showed the expected 2-log10 reduction in HIV RNA level, and 2 experienced early virologic failure. Overall, 97.5% (CI, 89.1% to 99.8%) were projected to achieve virologic suppression by a median of 33 weeks. The current virologic failure rate of 1.5% in the cohort is similar to that across registrational clinical trials at 48 weeks. Limitation: Single-site study. Conclusion: This project demonstrates the ability of LA-ART to achieve virologic suppression among PWH, including those with viremia and challenges to adherence. Further data on the ability of LA-ART to achieve viral suppression in people with barriers to adherence are needed.

Comparative Effectiveness of Sodium–Glucose Cotransporter-2 Inhibitors for Recurrent Gout Flares and Gout-Primary Emergency Department Visits and Hospitalizations: A General Population Cohort Study: Annals of Internal Medicine: Vol 176, No 8

Background: Sodium–glucose cotransporter-2 inhibitors (SGLT2is) decrease serum urate levels, but whether this translates into prevention of recurrent flares among patients with gout and gout-primary emergency department (ED) visits or hospitalizations is unknown. Objective: To compare gout flares and cardiovascular events among patients with gout initiating SGLT2is versus dipeptidyl peptidase 4 inhibitors (DPP-4is), another second-line glucose-lowering agent not associated with serum urate levels or cardiovascular risk. Design: Propensity score–matched, new-user cohort study. Setting: General population database from 1 January 2014 to 30 June 2022. Participants: Patients with gout and type 2 diabetes. Measurements: The primary outcome was recurrent gout flare counts ascertained by ED, hospitalization, outpatient, and medication dispensing records. Secondary outcomes included myocardial infarction and stroke; genital infection (positive control) and osteoarthritis encounter (negative control) were also assessed. Poisson and Cox proportional hazards regressions were used with 1:1 propensity score matching (primary analysis) and overlap weighting (sensitivity analysis). Results: After propensity score matching, the flare rate was lower among SGLT2i initiators than DPP-4i initiators (52.4 and 79.7 events per 1000 person-years, respectively), with a rate ratio (RR) of 0.66 (95% CI, 0.57 to 0.75) and a rate difference (RD) of −27.4 (CI, −36.0 to −18.7) per 1000 person-years. The corresponding RR and RD for gout-primary ED visits and hospitalizations were 0.52 (CI, 0.32 to 0.84) and −3.4 (CI, −5.8 to −0.9) per 1000 person-years, respectively. The corresponding hazard ratio (HR) and RD for myocardial infarction were 0.69 (CI, 0.54 to 0.88) and −7.6 (CI, −12.4 to −2.8) per 1000 person-years; the HR for stroke was 0.81 (CI, 0.62 to 1.05). Those who initiated SGLT2is showed higher risk for genital infection (HR, 2.15 [CI, 1.39 to 3.30]) and no altered risk for osteoarthritis encounter (HR, 1.07 [CI, 0.95 to 1.20]). Results were similar when propensity score overlap weighting was applied. Limitation: Participants had concurrent type 2 diabetes. Conclusion: Among patients with gout, SGLT2is may reduce recurrent flares and gout-primary ED visits and hospitalizations and may provide cardiovascular benefits.

Disparities in Guideline-Recommended Statin Use for Prevention of Atherosclerotic Cardiovascular Disease by Race, Ethnicity, and Gender: A Nationally Representative Cross-Sectional Analysis of Adults in the United States: Annals of Internal Medicine: Vol 176, No 8

Background: Although statins are a class I recommendation for prevention of atherosclerotic cardiovascular disease and its complications, their use is suboptimal. Differential underuse may mediate disparities in cardiovascular health for systematically marginalized persons. Objective: To estimate disparities in statin use by race–ethnicity–gender and to determine whether these potential disparities are explained by medical appropriateness of therapy and structural factors. Design: Cross-sectional analysis. Setting: National Health and Nutrition Examination Survey from 2015 to 2020. Participants: Persons eligible for statin therapy based on 2013 and 2018 American College of Cardiology/American Heart Association blood cholesterol guidelines. Measurements: The independent variable was race–ethnicity–gender. The outcome of interest was use of a statin. Using the Institute of Medicine framework for examining unequal treatment, we calculated adjusted prevalence ratios (aPRs) to estimate disparities in statin use adjusted for age, disease severity, access to health care, and socioeconomic status relative to non-Hispanic White men. Results: For primary prevention, we identified a lower prevalence of statin use that was not explained by measurable differences in disease severity or structural factors among non-Hispanic Black men (aPR, 0.73 [95% CI, 0.59 to 0.88]) and non-Mexican Hispanic women (aPR, 0.74 [CI, 0.53 to 0.95]). For secondary prevention, we identified a lower prevalence of statin use that was not explained by measurable differences in disease severity or structural factors for non-Hispanic Black men (aPR, 0.81 [CI, 0.64 to 0.97]), other/multiracial men (aPR, 0.58 [CI, 0.20 to 0.97]), Mexican American women (aPR, 0.36 [CI, 0.10 to 0.61]), non-Mexican Hispanic women (aPR, 0.57 [CI, 0.33 to 0.82), non-Hispanic White women (aPR, 0.69 [CI, 0.56 to 0.83]), and non-Hispanic Black women (aPR, 0.75 [CI, 0.57 to 0.92]). Limitation: Cross-sectional data; lack of geographic, language, or statin-dose data. Conclusion: Statin use disparities for several race–ethnicity–gender groups are not explained by measurable differences in medical appropriateness of therapy, access to health care, and socioeconomic status. These residual disparities may be partially mediated by unobserved processes that contribute to health inequity, including bias, stereotyping, and mistrust.

Association Between Vascular 18F-Fluorodeoxyglucose Uptake at Diagnosis and Change in Aortic Dimensions in Giant Cell Arteritis: A Cohort Study: Annals of Internal Medicine: Vol 176, No 10

Background: Previous studies have shown that patients with giant cell arteritis (GCA) who have vascular 18F-fluorodeoxyglucose (FDG) uptake at diagnosis are at increased risk for thoracic aortic complications. Objective: To measure the association between vascular FDG uptake at diagnosis and the change in aortic dimensions. Design: Prospective cohort study. Setting: University Hospitals Leuven. Patients: 106 patients with GCA and FDG positron emission tomography (PET) imaging 3 days or less after initiation of glucocorticoids. Measurements: Patients had PET and computed tomography (CT) imaging at diagnosis and CT imaging yearly for a maximum of 10 years. The PET scans were scored 0 to 3 in 7 vascular areas and summed to a total vascular score (TVS). The PET scan results were positive when FDG uptake was grade 2 or greater in any large vessel. The association between vascular FDG uptake and aortic dimensions was estimated by linear mixed-effects models with random intercept and slope. Results: When compared with patients with a negative PET scan result, those with a positive scan result had a greater increase in the diameter of the ascending aorta (difference in 5-year progression, 1.58 mm [95% CI, 0.41 to 2.74 mm]), the diameter of the descending aorta (1.32 mm [CI, 0.38 to 2.26 mm]), and the volume of the thoracic aorta (20.5 cm³ [CI, 4.5 to 36.5 cm³]). These thoracic aortic dimensions were also positively associated with TVS. Patients with a positive PET scan result had a higher risk for thoracic aortic aneurysms (adjusted hazard ratio, 10.21 [CI, 1.25 to 83.3]). Limitation: The lengthy inclusion and follow-up period resulted in missing data and the use of different PET machines. Conclusion: Higher TVS was associated with greater yearly increase in thoracic aortic dimensions. Performing PET imaging at diagnosis may help to estimate the risk for aortic aneurysm formation.

How Would You Manage This Patient With Recurrent Diverticulitis?: Grand Rounds Discussion From Beth Israel Deaconess Medical Center: Annals of Internal Medicine: Vol 176, No 6

Acute diverticulitis, which refers to inflammation or infection, or both, of a colonic diverticulum, is a common medical condition that may occur repeatedly in some persons. It most often manifests with left-sided abdominal pain, which may be associated with low-grade fever and other gastrointestinal symptoms. Complications may include abscess, fistula formation, perforation, and bowel obstruction. The American College of Physicians recently published practice guidelines on the diagnosis and management of acute diverticulitis, the role of colonoscopy after resolution, and interventions to prevent recurrence of this condition. Among the recommendations were the use of abdominal computed tomography (CT) scanning in cases where there was diagnostic uncertainty, initial management of uncomplicated cases in the outpatient setting without antibiotics, referral for colonoscopy after an initial episode if not performed recently, and discussion of elective surgery to prevent recurrent disease in patients with complicated diverticulitis or frequent episodes of uncomplicated disease. Here, 2 gastroenterologists with expertise in acute diverticulitis debate CT scanning for diagnosis, antibiotics for treatment, colonoscopy to screen for underlying malignancy, and elective surgery to prevent recurrent disease.
