Concurrent Alcohol and Opioid Intoxication in Emergency Department Patients Leads to Greater Resource Utilization.

Background: Concurrent alcohol intoxication can complicate emergency department (ED) presentations for opioid-related adverse events. We sought to determine if there was a difference in resource utilization among patients who presented to the ED with concurrent opioid and alcohol intoxication compared to opioid intoxication alone. Methods: Using linked state-wide databases from the Maryland Healthcare Cost and Utilization Project (HCUP), we identified patients with a diagnosis of opioid intoxication treated in the ED from 2016 to 2018. We measured healthcare utilization for each patient in the ED settings for one year after the initial ED visit and estimated direct costs. We performed logistic regression comparing patients presented with co-intoxication to those without. Results: Of 12,295 patients who presented to the ED for opioid intoxication during the study period, 703 (5.7%) had concurrent alcohol intoxication. Patients with co-intoxication had more recurrent ED visits (340 vs 247.4 per 1000 patients, p < 0.05), higher index ED visit admission rates (26.9% vs 19.4%, p < 0.001), but similar overall costs ($3736 vs $2861, p < 0.05) at one year. Co-intoxication was associated with suicidal ideation (OR = 1.58, 95% CI 1.51-1.65), high zip code income (OR = 1.16, 95% CI 1.12-1.21), and higher rates of intoxication with all classes of drugs analyzed (p < 0.001). Conclusion: Our study demonstrated that mental health disorders, socioeconomic status, and increased ED utilization are associated with co-intoxication of opioids and alcohol presenting to the ED. Further research is needed to elucidate factors responsible for the increased resource use in this population.

An Atypical Presentation of a Polyarticular Gout Flare: Case Report.

A 54-year-old man with a history of hypertension, atrial fibrillation, chronic kidney disease, nonischemic cardiomyopathy, osteoarthritis, and gout presented to the emergency department (ED) with dysuria, painful scrotal swelling, severe bilateral flank pain, back pain, atraumatic right arm (elbow and distally) pain and swelling, and bilateral knee pain. His physical exam was notable for fever, tachycardia, bilateral costovertebral angle (CVA) tenderness, exquisite pain, erythema, and swelling of bilateral knees and the right arm (elbow and distally). He met Systemic Inflammatory Response Syndrome (SIRS) criteria, was placed on Ceftriaxone for presumed septic pyelonephritis, and was admitted to the medicine team. With initially unremarkable imaging studies, the differential diagnosis was broadened, and subsequent infectious workups yielded grossly normal results. At the end of hospital day one, the patient remained febrile and without symptomatic improvement. Rheumatology was consulted and empirically treated; the patient with a dose of Anakinra due to concerns about a polyarticular flare of crystalline arthropathy. Subsequent arthrocentesis confirmed a final diagnosis of a polyarticular gout flare. This case highlights the diagnostic challenges a polyarticular gout flare poses and the importance of early involvement of specialists for prompt recognition, treatment, and avoidance of unnecessary interventions.

Remote Patient Monitoring for Hypertension: Feasibility and Outcomes of a Clinic-Based Pilot in a Minority Population.

BACKGROUND: In the US 48% of adults have hypertension, with direct costs in excess of $130 billion per year. Remote patient monitoring (RPM) has been discussed as a useful tool in the treatment of hypertension, but few studies evaluate its cost effectiveness or efficacy in minority, lower socio-economic (SES) populations. Our study aims to evaluate the clinical and financial outcomes of RPM in hypertension management in a primarily minority, low-SES population. METHODS: In this prospective cohort pilot study, patients with uncontrolled primary hypertension (defined via Joint National Committee 8 guidelines) were randomly selected from a single academically affiliated primary care clinic. Patients were enrolled on a rolling basis for 90 days. Patients were given blood pressure cuffs and transmission hubs and asked to transmit daily blood pressure readings. Patients were called weekly by research assistants and concerns were escalated to the primary care physician. The control group was the remaining 299 uncontrolled hypertensive patients from the same clinic population analyzed via retrospective chart records at the conclusion of the interventional study period. The primary outcome was blood pressure control. Secondary outcomes were relative improvement in systolic pressure and direct costs. RESULTS: A total of 13 patients were enrolled into the RPM intervention; these patients were 54% female, 100% African American, and 77% Medicaid. When assessed via intention-to-treat analysis, patients in the intervention group had non-inferior blood pressure control at 90 days (46% experimental vs 31% control, P = .33) and average change in systolic blood pressure at 90 days (13.5 vs 3.7 mmHg, P = .174) while experiencing a significant reduction in office-based visits at 90 days (1.5 vs 5.9, P < .001) as compared to control. Results on per-protocol analysis also showed non-inferior BP control (63% vs 31%, P = .135). Financially, the program generated margins of $29 per patient at 90 days. CONCLUSIONS: Patients in our minority- and Medicaid-predominant cohort achieved noninferior blood pressure control as compared to retrospective control at 90 days and a significant reduction in all-cause clinic visits at 90 days. The program generated little revenue per patient, with main barriers to implementation including patient compliance and payor denial.

Biliary colic in the emergency department: A state-wide analysis of one-year costs and clinical outcomes.

Importance: Approximately 335,000 cases of biliary colic present to US emergency departments (EDs) annually, and most patients without complications are discharged from the ED. It is unknown what are the subsequent surgery rates, subsequent complications of biliary disease, ED revisits, repeat hospitalizations and cost; and, how does the ED disposition decision (admission versus discharge) affect long-term outcomes. Objective: To determine whether there is a difference in one-year surgery rates, complications of biliary disease, ED revisits, repeat hospitalizations, and cost in ED patients with uncomplicated biliary colic who are admitted to the hospital versus those that are discharged from the ED. Design setting and participants: A retrospective observational study was conducted using records collected from the Maryland Healthcare Cost and Utilization Project (HCUP) in the Ambulatory Surgery, the Inpatient, and the ED setting between 2016 and 2018. After applying inclusion criteria, 7036 ED patients with uncomplicated biliary colic were followed for one year after their index ED visit for repeat healthcare utilization across multiple settings. A multivariable logistic regression study was performed to asses for risk factors for surgery allocation and hospital admission. Medicare Relative Value Units (RVUs) and HCUP Cost-Charge Ratio files were used to estimate direct costs. Exposures: Episodes of biliary colic were ascertained using ICD-10 codes at the index ED visit. Main outcomes and measures: The primary outcome was the one-year surgery rate, defined as a cholecystectomy. Secondary outcomes included the rate of new acute cholecystitis or other related complications, ED revisits, hospital admission and costs. Associations with hospital admission and surgeries were measured using adjusted odds ratios (ORs) with 95 % CIs. Results: Of the 7036 patients analyzed, 793 (11.3 %) were admitted and 6243 (88.7 %) were discharged on their initial ED visit. When comparing the groups who were initially admitted versus discharged, we observed similar one-year cholecystectomy rates (42 % versus 43 %, mean difference 0.5 %, 95 % CI -3.1 %-4.2 %; P < 0.001), lower rates of new cholecystitis occurrences (18 % versus 41 %, mean difference 23 %, 95 % CI, 20 %-26 %; P < 0.001), lower rates of ED revisits (96 vs 198 per 1000 patients, mean difference 102, 95 % CI, 74-130; P < 0.001) and higher costs ($9880 versus $1832, mean difference 8048, 95 % CI, 7478-8618; P < 0.001). Initial ED hospital admission was associated with increased age (adjusted odds ratio [aOR], 1.44; 95 % CI, 1.35-1.53; P < 0.001), obesity (aOR, 1.38; 95 % CI, 1.32-1.44; P < 0.001), ischemic heart disease (aOR, 1.39; 95 % CI, 1.30-1.48; P < 0.001), mood disorders (aOR, 1.18; 95 % CI, 1.13-1.24; P < 0.001), alcohol-related disorders (aOR, 1.20; 95 % CI, 1.12-1.27; P < 0.001), hyperlipidemia (aOR, 1.16; 95 % CI, 1.09-1.23; P < 0.001), hypertension (aOR, 1.15; 95 % CI, 1.08-1.21; P < 0.001), and nicotine dependence (aOR, 1.09; 95 % CI, 1.03-1.15; P = 0.003) but not associated with race (P > 0.9), ethnicity (P > 0.9), or income-stratified zip code (aOR, 1.04; 95 % CI, 0.98-1.09; P = 0.17). Conclusions and relevance: In our analysis of ED patients with uncomplicated biliary colic from a single state, the majority of patients do not receive a cholecystectomy within one year and hospital admission at the initial visit was not associated with an overall change in rates of cholecystectomy but was associated with increased costs. These findings inform our understanding of the long-term outcomes and are important considerations when communicating care options with ED patients with biliary colic.

Patients with complicated gallstone disease in the emergency department: clinical impact and cost-effectiveness of emergency department disposition decision.

Objective: The objective of this study was to assess the 1-year outcomes of emergency department (ED) patients with complicated gallstone disease, including surgery rates, initial admission rates, ED revisits, repeat hospitalizations, and cost. Methods: Using 3 linked statewide databases from the Maryland Healthcare Cost and Utilization Project, we identified patients with a primary diagnosis of complicated gallstone disease treated in an ED between 2016 and 2018. We measured the healthcare use and direct costs in the ambulatory surgery, inpatient, and ED settings for 1 year after the initial ED visit. Finally, we performed a multivariate logistic regression analysis comparing initially admitted versus discharged patients. Results: Of the 8751 patients analyzed, 86.8% were admitted to the hospital and 13.2% were discharged on their initial ED visit. Of the admitted patients, 78.7% received a cholecystectomy during the initial hospitalization plus 6.1% at a later date; of the discharged patients, 41.5% received a cholecystectomy. Admitted patients demonstrated lower recurrent gallbladder complications compared with those discharged (7.5% vs 44.5%), fewer ED revisits (4% vs 20.3%), and fewer repeat hospitalizations (4.5% vs 16.7%). Despite this, the 1-year cost in the admitted patients was higher ($9448 vs $2933). Obesity, age, and mood disorders but not race, ethnicity, or zip code were associated with admission at initial ED visit. Conclusions: In our single-state analysis of ED patients with complications of gallstone disease, most patients are admitted on the initial visit and receive a cholecystectomy during that hospitalization. The discharged group had higher rates of 1-year complications, ED revisits, and repeat hospitalizations but lower cost.
