Perspectives of Physicians and Nurse Practitioners on Primary Care Practice
In this national survey, primary care physicians were more likely than primary care nurse practitioners to believe that physicians provide a higher quality of care than nurse practitioners and were less likely to believe that physicians and nurse practitioners should be paid equally for the same services. The U.S. health care system is at a critical juncture in health care workforce planning. The nation has an acknowledged shortage of primary care physicians at a time when the population is aging and the incidence and prevalence of chronic illnesses are increasing. The implementation of the Affordable Care Act will provide millions of previously uninsured Americans with the means to purchase health insurance and access health care services. 1 – 3 The combination of increased demand and provider shortages has led policymakers to consider increasing the supply of nurse practitioners and broadening their roles in the provision of primary care. 4 , . . .
Incidence and Risk Factors for Intensive Care Unit–related Post-traumatic Stress Disorder in Veterans and Civilians
Abstract Rationale The incidence and risk factors of post-traumatic stress disorder (PTSD) related to the intensive care unit (ICU) experience have not been reported in a mixed veteran and civilian cohort. Objectives To describe the incidence and risk factors for ICU-related PTSD in veterans and civilians. Methods This is a prospective, observational, multicenter cohort enrolling adult survivors of critical illness after respiratory failure and/or shock from three Veterans Affairs and one civilian hospital. After classifying those with/without preexisting PTSD (i.e., PTSD before hospitalization), we then assessed all subjects for ICU-related PTSD at 3 and 12 months post hospitalization. Measurements and Main Results Of 255 survivors, 181 and 160 subjects were assessed for ICU-related PTSD at 3- and 12-month follow-up, respectively. A high probability of ICU-related PTSD was found in up to 10% of patients at either follow-up time point, whether assessed by PTSD Checklist Event-Specific Version (score ≥ 50) or item mapping using the Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV). In the multivariable regression, preexisting PTSD was independently associated with ICU-related PTSD at both 3 and 12 months (P < 0.001), as was preexisting depression (P < 0.03), but veteran status was not a consistent independent risk factor for ICU-related PTSD (3-month P = 0.01, 12-month P = 0.48). Conclusions This study found around 1 in 10 ICU survivors experienced ICU-related PTSD (i.e., PTSD anchored to their critical illness) in the year after hospitalization. Preexisting PTSD and depression were strongly associated with ICU-related PTSD.
Long-term Cognitive and Psychological Outcomes in the Awakening and Breathing Controlled Trial
Abstract Rationale Studies have shown that reducing sedation of critically ill patients shortens time on the ventilator and in the intensive care unit (ICU). Little is known, however, of how such strategies affect long-term cognitive, psychological, and functional outcomes. Objectives To determine the long-term effects of a wake up and breathe protocol that interrupts and reduces sedative exposure in the ICU. Methods In this a priori planned substudy conducted at one tertiary care hospital during the Awakening and Breathing Controlled Trial, a multicenter randomized controlled trial, we assessed cognitive, psychological, and functional/quality-of-life outcomes 3 and 12 months postdischarge among 180 medical ICU patients randomized to paired daily spontaneous awakening trials with spontaneous breathing trials (SBTs) or to sedation per usual care plus daily SBTs. Measurements and Main Results Cognitive impairment was less common in the intervention group at 3-month follow-up (absolute risk reduction, 20.2%; 95% confidence interval, 1.5–36.1%; P = 0.03) but not at 12-month follow-up (absolute risk reduction, −1.9%; 95% CI, −21.3 to 27.1%; P = 0.89). Composite cognitive scores, alternatively, were similar in the two groups at 3-month and 12-month follow-up (P = 0.80 and 0.61, respectively), as were symptoms of depression (P = 0.59 and 0.82) and posttraumatic stress disorder (P = 0.59 and 0.97). Activities of daily living, functional status, and mental and physical quality of life were similar between groups throughout follow-up. Conclusions In this trial, management of mechanically ventilated medical ICU patients with a wake up and breathe protocol resulted in similar cognitive, psychological, and functional outcomes among patients tested 3 and 12 months post-ICU. The proven benefits of this protocol, including improved 1-year survival, were not offset by adverse long-term outcomes. Clinical trial registered with www.clinicaltrials.gov (NCT00097630).
The relationship between executive dysfunction, depression, and mental health-related quality of life in survivors of critical illness: Results from the BRAIN-ICU investigation
Although executive dysfunction and depression are common among intensive care unit (ICU) survivors, their relationship has not been evaluated in this population. We sought to determine (1) if executive dysfunction is independently associated with severity of depressive symptoms or worse mental health-related quality of life (HRQOL) in ICU survivors, and (2) if age modifies these associations. In a prospective cohort (n=136), we measured executive dysfunction by the Behavior Rating Inventory of Executive Function–Adult, depression by the Beck Depression Inventory-II, and mental HRQOL by the Short-Form 36. We used multiple linear regression models, adjusting for potential confounders. We included age as an interaction term to test for effect modification. Executive dysfunction 3 months post-ICU was independently associated with more depressive symptoms and worse mental HRQOL 12 months post-ICU (25th vs 75th percentile of executive functioning scored 4.3 points worse on the depression scale [95% confidence interval, 1.3-7.4; P=.015] and 5 points worse on the Short-Form 36 [95% confidence interval, 1.7-8.3; P=.006]). Age did not modify these associations (depression: P=.12; mental HRQOL: P=.80). Regardless of age, executive dysfunction was independently associated with subsequent worse severity of depressive symptoms and worse mental HRQOL. Executive dysfunction may have a key role in the development of depression.
Incidence of Emergency Department Visits for ST-Elevation Myocardial Infarction in a Recent Six-Year Period in the United States
The incidence and longitudinal trends of patients with ST-elevation myocardial infarction (STEMI) presenting to United States (US) emergency departments (EDs) are currently unknown. Efforts to use effective treatments for cardiovascular disease may decrease ED STEMI presentation. We conducted a descriptive epidemiological analysis of STEMI visits to EDs from 2006 to 2011 using the Nationwide ED Sample, the largest source of US ED data, to determine the incidence of patients with STEMIs presenting to the US EDs. We included adult ED visits with an International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis of STEMI and calculated incidence rates for STEMI ED visits using US census population data. Incidence calculations were stratified by age group, geographic region, and year. From 2006 to 2011, there was a mean of 258,106 STEMIs presenting to EDs per year, decreasing from 300,466 in 2006 to 227,343 in 2011. Incidence of ED STEMI visits per 10,000 adults decreased from 10.1 (95% confidence interval [CI] 9.8 to 10.8) in 2006 to 7.3 (95% CI 6.8 to 7.8) in 2011. The Midwest had the highest rate of ED STEMIs at 10.0 (95% CI 9.2 to 10.8) and the West had the lowest with 6.6 (95% CI 6.1 to 7.0). The incidence of STEMI decreased for all age groups during the study period. In conclusion, we report the first national estimates of STEMI presentation to US EDs, which demonstrate decreasing incidence across all age groups and all geographic regions from 2006 to 2011. A decreasing STEMI incidence may affect the quality and timeliness of STEMI care. Continued national STEMI surveillance is needed to guide healthcare resource allocation.
Interruptive versus Non-Interruptive Reminders for Statin tHerApy in Primary Care (INIRSHA-PC): protocol and statistical analysis plan for a randomised clinical trial
IntroductionStatins are a cornerstone of cardiovascular disease prevention yet remain underused among eligible patients. Clinical decision support systems embedded in electronic health records (EHRs) are commonly used to encourage guideline-concordant prescribing. Interruptive reminders (eg, pop-ups) may be effective but interfere with clinical workflows and contribute to alert fatigue. Non-interruptive alerts are less intrusive, but their effectiveness remains unclear. The Interruptive versus Non-Interruptive Reminders for Statin tHerApy in Primary Care (INIRSHA-PC) trial is designed to evaluate the comparative effectiveness of interruptive and non-interruptive reminders on statin-prescribing rates.Methods and analysisINIRSHA-PC is a single-centre, pragmatic, three-arm, parallel-group randomised controlled trial embedded in the EHR at Vanderbilt University Medical Center. The trial will enrol adults aged 18–74 seen in primary care who are eligible for, but not currently prescribed, statin therapy. The planned sample size is 3000 patients (1000 per arm). Enrolled patients will be randomised 1:1:1 to (1) interruptive reminder, (2) non-interruptive reminder or (3) no reminder (usual care). The primary outcome is statin prescription within 24 hours of enrolment. Secondary outcomes are statin prescribing within 12 months and low-density lipoprotein cholesterol levels measured between 30 days and 12 months after enrolment. Enrolment began on 14 August 2024. The study is expected to be completed on 19 November 2025.Ethics and disseminationThe trial has been approved by the Vanderbilt University Medical Center Institutional Review Board with waiver of patient informed consent (IRB number: 240419). Results will be disseminated through peer-reviewed publication and presentation at scientific conferences.Trial registration numberNCT06456658.
Evidence-based smoking cessation treatment: a comparison by healthcare system
Background A systems-level approach to smoking cessation treatment may optimize healthcare provider adherence to guidelines. Institutions such as the Veterans Health Administration (VHA) are unique in their systematic approach, but comparisons of provider behavior in different healthcare systems are limited. Methods We surveyed general medicine providers and specialists in a large academic health center (AHC) and its affiliated VHA in the Mid-South in 2017 to determine the cross-sectional association of healthcare system in which the provider practiced (exposure: AHC versus VHA) with self-reported provision of evidence-based smoking cessation treatment (delivery of counseling plus smoking cessation medication or referral) at least once in the past 12 months (composite outcome). Multivariable logistic regression with adjustment for specialty was performed in 2017–2019. Results Of 625 healthcare providers surveyed, 407 (65%) responded, and 366 (59%) were analyzed. Most respondents practiced at the AHC (273[75%] vs VHA 93[25%]) and were general internists (215[59%]); pulmonologists (39[11%]); hematologists/oncologists (69[19%]); and gynecologists (43[12%]). Most respondents (328[90%]) reported the primary outcome. The adjusted odds of evidence-based smoking cessation treatment were higher among VHA vs. AHC healthcare providers (aOR = 4.3; 95% CI 1.3–14.4; p  = .02). Health systems differed by provision of individual treatment components, including smoking cessation medication use (98% VHA vs. 90% AHC, p  = 0.02) and referral to smoking cessation services (91% VHA vs. 65% AHC p  = 0.001). Conclusions VHA healthcare providers were significantly more likely to provide evidence-based smoking cessation treatment compared to AHC healthcare providers. Healthcare systems’ prioritization of and investment in smoking cessation treatment is critical to improving providers’ adherence to guidelines.
An evaluation of single question delirium screening tools in older emergency department patients
To determine the diagnostic performances of several single question delirium screens. To the patient we asked: “Have you had any difficulty thinking clearly lately?” To the patient's surrogate, we asked: “Is the patient at his or her baseline mental status?” and “Have you noticed the patient's mental status fluctuate throughout the course of the day?” This was a prospective observational study that enrolled English speaking patients 65 years or older. A research assistant (RA) and emergency physician (EP) independently asked the patient and surrogate the single question delirium screens. The reference standard for delirium was a consultation-liaison psychiatrist's assessment using Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) criteria. All assessments were performed within 3 h and were all blinded to each other. Of the 406 patients enrolled, 50 (12%) were delirious. A patient who was unable to answer the question “Have you had any difficulty thinking clearly lately?” was 99.7% (95% CI: 98.0%–99.9%) specific, but only 24.0% (95% CI: 14.3%–37.4%) sensitive for delirium when asked by the RA. The baseline mental status surrogate question was 77.1% (95% CI: 61.0%–87.9%) sensitive and 87.5% (95% CI: 82.8%–91.1%) specific for delirium when asked by the RA. The fluctuating course surrogate question was 77.1% (95% CI: 61.0%–87.9%) sensitive and 80.2% (95% CI: 74.8%–84.7%) specific. When asked by the EP, the single question delirium screens' diagnostic performances were similar. The patient and surrogate single question delirium assessments may be useful for delirium screening in the ED.
Role of Health Insurance Status in Interfacility Transfers of Patients With ST-Elevation Myocardial Infarction
Lack of health insurance is associated with interfacility transfer from emergency departments for several nonemergent conditions, but its association with transfers for ST-elevation myocardial infarction (STEMI), which requires timely definitive care for optimal outcomes, is unknown. Our objective was to determine whether insurance status is a predictor of interfacility transfer for emergency department visits with STEMI. We analyzed data from the 2006 to 2011 Nationwide Emergency Department Sample examining all emergency department visits for patients age 18 years and older with a diagnosis of STEMI and a disposition of interfacility transfer or hospitalization at the same institution. For emergency department visits with STEMI, our multivariate logistic regression model included emergency department disposition status (interfacility transfer vs hospitalization at the same institution) as the primary outcome, and insurance status (none vs any [including Medicare, Medicaid, and private insurance]) as the primary exposure. We found that among 1,377,827 emergency department STEMI visits, including 249,294 (18.1%) transfers, patients without health insurance (adjusted odds ratio 1.6, 95% CI 1.5 to 1.7) were more likely to be transferred than those with insurance. Lack of health insurance status was also an independent risk factor for transfer compared with each subcategory of health insurance, including Medicare, Medicaid, and private insurance. In conclusion, among patients presenting to United States emergency departments with STEMI, lack of insurance was an independent predictor of interfacility transfer. In conclusion, because interfacility transfer is associated with longer delays to definitive STEMI therapy than treatment at the same facility, lack of health insurance may lead to important health disparities among patients with STEMI.
Frailty and Subsequent Disability and Mortality among Patients with Critical Illness
The prevalence of frailty (diminished physiologic reserve) and its effect on outcomes for those aged 18 years and older with critical illness is unclear. We hypothesized greater frailty would be associated with subsequent mortality, disability, and cognitive impairment, regardless of age. At enrollment, we measured frailty using the Clinical Frailty Scale (range, 1 [very fit] to 7 [severely frail]). At 3 and 12 months post-discharge, we assessed vital status, instrumental activities of daily living, basic activities of daily living, and cognition. We used multivariable regression to analyze associations between Clinical Frailty Scale scores and outcomes, adjusting for age, sex, education, comorbidities, baseline disability, baseline cognition, severity of illness, delirium, coma, sepsis, mechanical ventilation, and sedatives/opiates. We enrolled 1,040 patients who were a median (interquartile range) of 62 (53-72) years old and who had a median Clinical Frailty Scale score of 3 (3-5). Half of those with clinical frailty (i.e., Clinical Frailty Scale score ≥5) were younger than 65 years old. Greater Clinical Frailty Scale scores were independently associated with greater mortality (P = 0.01 at 3 mo and P < 0.001 at 12 mo) and with greater odds of disability in instrumental activities of daily living (P = 0.04 at 3 mo and P = 0.002 at 12 mo). Clinical Frailty Scale scores were not associated with disability in basic activities of daily living or with cognition. Frailty is common in critically ill adults aged 18 years and older and is independently associated with increased mortality and greater disability. Future studies should explore routine screening for clinical frailty in critically ill patients of all ages. Interventions to reduce mortality and disability among patients with heightened vulnerability should be developed and tested. Clinical trial registered with www.clinicaltrials.gov (NCT 00392795 and NCT 00400062).
