Disparities in the management of non-ST-segment elevation myocardial infarction in the United States.

Guidelines recommend managing patients aged ≥75 with non-ST-segment elevation myocardial infarction (NSTEMI) similar to younger patients. We analyze disparities in NSTEMI management and compare those ≥80 years to those <80 years. This is a matched case-control study using the 2016 National Inpatient Sample data of adults with NSTEMI receiving percutaneous coronary intervention with drug-eluting stent (PCI-DES) - one artery or no intervention. We included the statistically significant variables in univariate analysis in exploratory multivariate logistic regression models. Total sample included 156,328 patients, out of which 43,265 were ≥ 80 years, and 113,048 were < 80 years. Patients ≥80 years were more likely to not have an intervention (73.3%) when compared to those <80 (44.1%), P < 0.0005. Regardless of age, PCI-DES-one artery improved survival compared to no intervention (Age < 80: OR 0.230, 95% CI 0.189-0.279, and ≥ 80: OR 0.265, 95% CI 0.195-0.361, P < 0.0005). Women (OR 0.785, 95% CI 0.766-0.804, P < 0.0005) and non-white race (OR 0.832, 95% CI 0.809-0.855, P < 0.0005) were less likely to receive an intervention. Non-Medicare/Medicaid insurance was associated with 40% lower likelihood of dying in <80 age group (OR 0.596, 95% CI 0.491-0.724, P < 0.0005), and 16% higher chance of intervention overall (OR 1.160, 95% CI 1.125-1.197, P < 0.0005). Patients aged ≥80 with NSTEMI were 29% less likely to receive an intervention compared to patients aged <80, even though patients >80 derived similar mortality benefits from the intervention. There were gender, payor, and race-based disparities in NSTEMI management in 2016.

Evolution of prescribing practices and outcomes in the COVID-19 pandemic in metropolitan areas.

Introduction: We wanted to characterize the evolution of the COVID-19 pandemic in a typical metropolitan area. Methods: Data were extracted from the Detroit COVID-19 Consortium database for hospitalized COVID-19 patients treated in Southeast Michigan over the 12-month period from March 2020 to February 2021. Demographic and outcomes data were compared to CDC data. Results: A total of 4,775 patients were enrolled during the study period. We divided the pandemic into three phases: Phase-1 (Spring Surge); Phase-2 (Summer Lull); and Phase-3 (Fall Spike). Changes in hydroxychloroquine, remdesivir, corticosteroid, antibiotic and anticoagulant use closely followed publication of landmark studies. Mortality in critically-ill patients decreased significantly from Phase-1 to Phase-3 (60.3% vs. 47.9%, Chisq p=0.0110). Monthly mortality of all hospitalized patients ranged between 14.8% - 21.5% during Phase-1 and 9.7 to 13.4% during Phase 3 (NS). Discussion: The COVID-19 pandemic presented in three unique phases in Southeast Michigan. Medical systems rapidly modified treatment plans, often preceding CDC and NIH recommendations. Despite improved treatment regimens, intubation rates and mortality for hospitalized patients remained elevated. Conclusion: Preventive measures aimed at reducing hospitalizations for COVID-19 should be emphasized.

Risk Factors in Hospitalized Patients for Heparin-Induced Thrombocytopenia by Real World Database: A New Role for Primary Hypercoagulable States.

Background: The aims of the study were to identify predictors of heparin-induced thrombocytopenia (HIT) in hospitalized adults, and to find additional factors associated with higher odds of HIT in primary hypercoagulable states. Methods: A retrospective matched case-control study using discharge data from National Inpatient Sample database (2012 - 2014) was conducted. In primary outcome analysis, hospitalized patients with and without HIT were included as cases and controls, both matched for age and gender. In secondary outcome analysis, hospitalized patients with primary hypercoagulable states with and without HIT were included as cases and controls, both matched for age and gender. The statistical analyses were performed using Statistical Package for Social Sciences version 25. Results: There are several predictors of HIT in hospitalized patients, such as obesity, malignancy, diabetes, renal failure, major surgery, congestive heart failure, and autoimmune diseases. In patients with primary hypercoagulable states, the presence of renal failure (odds ratio (OR) 2.955, 95% confidence interval (CI) 1.994 - 4.380), major surgery (OR 1.735, 95% CI 1.275 - 2.361), congestive heart failure (OR 4.497, 95% CI 2.466 - 8.202), or autoimmune diseases (OR 1.712, 95% CI 1.120 - 2.618) further increases the odds of HIT. Conclusions: In hospitalized patients with primary hypercoagulable states, especially in association with renal failure, major surgery, congestive heart failure, or autoimmune diseases, unfractionated heparin should be used with caution.

Mortality risk stratification helps identify patients with COVID-19 at risk of adverse outcomes.

Mortality risk stratification can identify patients with COVID-19 who are at higher risk of mortality, discharge to skilled nursing facility, and readmission, and may benefit from focused intervention strategies.

Mortality risk stratification can predict readmissions but not length of stay.

OBJECTIVES: To determine whether the mortality risk stratification (MORIS) strata can predict outcomes including mortality, readmission, and discharge disposition for specific diagnoses. STUDY DESIGN: Retrospective, observational study for hospitalized patients in 2016-2017 at an urban, medium-sized, community tertiary care hospital. All admitted patients with 1 of the following diagnoses were included in this study: acute myocardial infarction, chronic obstructive pulmonary disease, congestive heart failure, pneumonia, and sepsis. METHODS: No interventions were applied in this retrospective study. Data collected from patients admitted under 1 of the 5 diagnoses included mortality, length of stay (LOS), readmission, and discharge disposition. RESULTS: MORIS strata can predict condition-specific mortality and readmissions but not length of stay or discharge disposition. CONCLUSIONS: Stewardship of resources is necessary to obtain high value in care. A long LOS, discharge to skilled nursing facilities, and unplanned readmissions contribute to a significant utilization of resources. The MORIS strata are useful in predicting disease-specific mortality and readmission, but they are not useful in predicting LOS or discharge disposition.

Desirable Features of an Interdisciplinary Handoff.

Failure of communication of critical information during handoffs is one of the leading causes of medical errors, resulting in serious, yet preventable, adverse events in hospitals across the United States. Recent studies have shown that a majority of these errors occur during patient handoffs, with notable communication gaps in interdisciplinary handoffs. We suggest some features that would improve the handoff usability and effectiveness for interdisciplinary medical and nursing teams while potentially improving patient safety.

Nitrofurantoin: friend or foe?

Nitrofurantoin remains the gold standard treatment of uncomplicated cystitis as well as prophylactic treatment of recurrent urinary tract infections. Drug-induced hepatotoxicity presents in acute (3 in 1 000 000) and chronic (1 in 1500) forms. We present a patient with acute liver failure after 5 days of treatment. A 69-year-old man admitted for chronic obstructive pulmonary disease exacerbation 5 days into treatment for cystitis with nitrofurantoin. On admission he was noted to be jaundiced with elevated liver enzymes and normal international normalised ratio. Investigation for infectious, autoimmune and cholestatic causes of hepatotoxicity was negative. The patient improved after discontinuation of the drug and 10 days of methylprednisolone. There are scant data on acute liver failure in the setting of short-term nitrofurantoin administration. The mechanism of toxicity remains unclear, but is hypothesised to be an autoimmune process in which steroids may play a role in treatment. Diagnosis is one of exclusion as the only definitive method of diagnosis is rechallenge.

Seizure Triggered by Sick Sinus Syndrome.

Sick sinus syndrome (SSS) is a dysfunction of sinoatrial node resulting in symptomatic bradycardia or sinus pauses causing decreased cardiac output with cerebral hypoperfusion and usually presents as syncope, presyncope or fatigue. The occurrence of a seizure is very rare. A 69-year-old man suffered two episodes of generalised tonic-clonic seizures. MRI and electroencephalogram failed to reveal the cause of seizures. In the emergency room, he experienced presyncope simultaneous to bradycardia and sinus pauses. He was stabilised with atropine and dopamine infusion and underwent definitive therapy with a permanent dual-chamber pacemaker with complete symptom resolution. Diagnostic confounders include convulsive syncope and ictal bradycardia. Syncope may be accompanied by myoclonic jerks (convulsive syncope), but postictal confusion is absent. Bradycardia may be seen during the postictal period (ictal bradycardia syndrome), but protracted sinus dysfunction is not present. Hypoperfusion due to significant SSS triggered seizures in this patient who may have an underlying predisposition.
