Primary care in the emergency department -- an untapped resource for public health research and innovation

The acute effect of systemic blood pressure reduction on intraocular pressure in hypertensive patients

OBJECTIVES:

Previous studies have shown an association between systemic hypertension and intraocular pressure (IOP). We analyzed the relationship between the decreases of the blood pressure (BP) and IOP in hypertensive patients.

METHODS:

The study includes a total of 214 patients: 158 hypertensive and 56 normotensive patients as study and control groups, respectively. The IOP of each eye in both the groups was measured once with a noncontact tonometer at presentation and an hour after BP reduction to normal in the study group. We analyzed the reduction in IOP with decreasing BP.

RESULTS:

In the study group, the mean IOP was 15.29 ± 4.05 mmHg in the right and 15.11 ± 3.78 mmHg in the left eyes. The mean IOP measured an hour after the patients became normotensive was 13.78 ± 4.06 mmHg in the right and 13.51 ± 3.82 in the left eyes. There was a statistically significant decrease in the IOPs (P < 0.001). The mean IOP in the control group was 13.54 ± 3.51 mmHg in the right and 13.20 ± 3.33 mmHg in the left eyes. The mean IOP at presentation in the study and control groups was found to be significantly different (P < 0.001).

CONCLUSIONS:

Patients in the study group showed a significantly higher IOP compared to patients in the normotensive group. Furthermore, patients in the study group showed a significant reduction in IOP after BP reduction. This may indicate that uncontrolled hypertension poses a risk for prolonged higher IOP. Prolonged higher IOP can be considered a risk factor for the glaucoma.

Revisiting racial disparities in ED CT utilization during the Affordable Care Act era: 2009-2018 data from the NHAMCS

OBJECTIVE

To examine the trends in CT utilization in the emergency department (ED) for different racial and ethnic groups, factors that may affect utilization, and the effects of increased insurance coverage since passage of the Affordable Care Act in 2010.

MATERIALS AND METHODS

Data from the National Hospital Ambulatory Medical Care Survey (NHAMCS) for the years 2009-2018 were used for the analysis. The NHAMCS is a cross-sectional survey which has random and systematical samples of more than 200,000 visits to over 250 hospital EDs in the USA. Patient demographic characteristics, source of payment/insurance, clinical presentation, and disposition from the ED were recorded. Descriptive statistics and multivariate logistic regression were performed.

RESULTS

Between 2009 and 2018, the rate of uninsured patients in the ED decreased from 18.1% to as low as 9.9%, but this was not associated with a decrease in the disparity in CT utilization between non-Hispanic Black and non-Hispanic White patients. CT use rate increased 38% over the study period. Factors strongly associated with CT utilization include age, source of payment, triage category, disposition from the ED, and residence. After controlling for these factors, non-Hispanic White patients were 21% more likely to undergo CT than non-Hispanic Black patients, though no disparity was seen for Hispanic or Asian/other groups.

CONCLUSION

Despite increased insurance coverage over the sample period, racial disparities between non-Hispanic Black and non-Hispanic White patients persist in CT utilization, though no disparity was seen for Hispanic or Asian/other patients. The source of this disparity remains unclear and is likely multifactorial.

Novel coronavirus: A capsule review for primary care and acute care physicians

Novel coronavirus (nCoV) is a new emerging infectious agent causing coronavirus disease 2019 (COVID-19). Since the reporting of early cases of COVID-19 from China on December 29, 2019 till March 15, 2020, it has affected 1,42,539 humans in 135 countries, including 82 cases in India. As it is a difficult task for first-contact physicians, i.e. primary care and acute care physicians, to comprehend the fast-growing knowledge about nCoV and apply for prevention and care of suspected cases of COVID-19, we have tried to provide an updated capsule review of nCoV infection and management of COVID-19. It includes the evidence-based information on epidemiological determinants (agent, host, and environment) of the disease, its clinical features, clinical and laboratory diagnosis, basic infection prevention and control measures, and clinical management of COVID-19 cases. This review also includes the succinct summary of World Health Organization and Center for Diseases Control and Prevention interim guidelines (as of March 15, 2020) on nCoV.

Institutional Pathways to Improve Care of Patients with Elevated Blood Pressure in the Emergency Department

PURPOSE OF REVIEW

Hypertension (HTN) is the most prevalent cardiovascular disease and poses a major population level risk to long-term health outcomes. Despite this critical importance, and the widespread availability of effective and affordable medications, blood pressure (BP) remains uncontrolled in up to 50% of the diagnosed patients. This problem is exacerbated in communities with limited access to primary care, who often utilize hospital emergency departments (EDs) as their primary healthcare resource. Despite the ubiquity of patients presenting to EDs with severely elevated BP, a unified, evidence-based approach is not yet widely implemented, and both under- and overtreatment are common. The purpose of this review is to describe an approach towards institutional policy regarding asymptomatic HTN, in which we will translate the accepted principles of appropriate outpatient BP management to ED and inpatient settings.

RECENT FINDINGS

Results from the recent SPRINT trial, and the subsequent publication of the American Heart Association updated guidelines for the treatment of HTN, significantly lower both the diagnostic threshold and the treatment goals for hypertensive patients. This change will drastically increase the proportion of patients presenting to EDs with newly diagnosed and uncontrolled HTN. Several recent studies emphasize the safety in outpatient management of patients with severely elevated BP in the absence of acute end-organ damage and, conversely, the long- and intermediate-term risk associated with these patients. System-based approaches, particularly those led by non-physicians, have shown the greatest promise in reducing population level uncontrolled HTN. Evidence-based approaches, such as those described in emergency medicine and cardiology society guidelines, can guide appropriate management of ED and inpatient BP elevations. Translating these patient oriented guidelines into institutional policy, and maintaining provider adherence, is a challenge across healthcare institutions. We present here several examples of successful policies developed and implemented by the authors. While brief inpatient and ED encounters cannot replace long-term outpatient care, they have the potential to serve as a crucial inlet to health care and an opportunity to optimize care.

Hot Topic: Global Burden of Treating Hypertension-What is the Role of the Emergency Department?

Hypertension (HTN) is the most common modifiable risk factor for cardiovascular disease (CVD) morbidity and mortality worldwide. Lower- and middle-income countries (LMICs) are projected to bear the vast majority of this disease burden, but local and regional health care delivery systems in these countries are ill equipped to meet this need. Emergency care is receiving increased recognition as a crucial component of public and community health. The rapid evolution of emergency care in LMICs provides a unique opportunity to develop innovative strategies, incorporating existing strengths of emergency departments, to address this paradigm shift in the disease burden associated with HTN on a global scale.
