Emergency Department Burden of Nausea and Vomiting Associated With Cannabis Use Disorder: US Trends From 2006 to 2013.

BACKGROUND AND AIMS: Chronic cannabis use is associated with nausea and vomiting that may lead to emergency department (ED) visits, multiple diagnostic tests, and procedures. The aim of this study was to analyze recent trends in ED visits for vomiting associated with cannabis use disorder between 2006 and 2013. METHODS: Data were obtained from the National Emergency Department Sample records in which vomiting (ICD-9-CM codes 787.01, 787.03, and 536.2) was a primary diagnosis in combination with cannabis abuse or dependence (304.3, 304.30, 304.31, 304.32, 304.33, 305.2, 305.20, 305.21, 305.22, and 305.23) and were seen in the ED between 2006 and 2013. The National Emergency Department Sample collects data from more than 25 million visits in over 950 EDs and is weighted to provide national estimates. RESULTS: The rate of ED visits for vomiting with cannabis use disorder from 2006 compared with 2013 increased from 2.3 to 13.3 per 100,000 ED visits, while the mean inflation-adjusted costs increased 68.5% from $2758.43 to $4647.62, respectively. Men between the ages of 20 and 29 were the most common group to present to the ED for vomiting with cannabis use disorder. The Midwest and West had the higher rates of ED visits for vomiting with cannabis use disorder compared with the Northeast and South. CONCLUSIONS: ED visits for vomiting associated with cannabis use disorder is common and is associated with significant medical costs. Further research on the role of cannabis use in nausea and vomiting is warranted.

Emergency Department Burden of Diverticulitis in the USA, 2006-2013.

GOALS: The aim of this study was to analyze recent trends in emergency department (ED) visits for diverticulitis between 2006 and 2013. BACKGROUND: Acute diverticulitis is a serious medical condition that frequently leads to ED visits, hospitalizations, and surgeries resulting in a significant health care burden. METHODS: Data were obtained from the National Emergency Department Sample (NEDS) records in which diverticulitis (ICD-9-CM codes 562.11 and 562.13) was the primary diagnosis in the ED between 2006 and 2013. The NEDS collects data from more than 25 million visits in over 950 hospital emergency departments and is weighted to provide national estimates. Our findings reflected patient and hospital characteristics such as demographics, geographical region, and total charges for ED and inpatient stays. RESULTS: Between 2006 and 2013, the rate of diverticulitis-related ED visits increased by 26.8% from 89.8 to 113.9 visits per 100,000 population. The aggregate national cost of diverticulitis-related ED visits increased by 105%, from approximately $822 million in 2006 to over $1.6 billion in 2013. Cost data were adjusted for inflation and reported in 2015 dollars. The percentage of individuals admitted to the same hospital from the ED decreased from 58.0 to 47.1% from 2006 to 2013, respectively, while the rate of bowel surgeries per 100,000 ED visits for diverticulitis decreased by 33.7% from 2006 to 2013. CONCLUSIONS: The number of ED visits due to diverticulitis and associated costs continued to rise between 2006 and 2013, while the rate of bowel surgeries and inpatient admissions through the ED for diverticulitis decreased.

Fecal Impaction in the Emergency Department: An Analysis of Frequency and Associated Charges in 2011.

GOALS: The aim of this study was to analyze the incidence and associated charges of fecal impaction for trends in hospital and patient demographics in emergency departments (ED) across the United States. BACKGROUND: In 2010, an ICD-9-CM code (560.32) for fecal impaction was introduced, allowing for assessment of fecal impaction incidence. STUDY: Data were obtained from the National Emergency Department Sample records in which fecal impaction (ICD-9-CM code 560.32) was first listed as a diagnosis in 2011. RESULTS: In 2011, there were 42,481 [95% confidence interval (CI), 39,908-45,054] fecal impaction ED visits, with an overall rate of 32 fecal impaction visits per 100,000 ED visits. Adjusted for inflation in 2014 dollars, the associated mean charge of a fecal impaction ED visit was $3060.47 (95% CI, $2943.02-$3177.92), with an aggregate national charge in the US of $130,010,772 (95% CI, $120,688,659-$139,332,885). All charges were adjusted for inflation and reported in 2014 dollars. Late elders (85+ y) had the highest rate of fecal impaction ED visits, followed by early elders (65 to 84 y). Medicare was the primary payer for the greatest number of fecal impaction ED visits accounting for nearly two thirds of visit payments. CONCLUSION: This study reports previously unexplored statistics on the number, frequency, and associated charges of ED visits with a primary diagnosis of fecal impaction, a condition found most commonly among elders.

Emergency department burden of constipation in the United States from 2006 to 2011.

OBJECTIVES: Although constipation is typically managed in an outpatient setting, there is an increasing trend in the frequency of constipation-related hospital visits. The aim of this study was to analyze trends related to chronic constipation (CC) in the United States with respect to emergency department (ED) visits, patient and hospital characteristics, and associated costs. METHODS: Data from 2006 to 2011, in which constipation (The International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) diagnosis codes 564.00-564.09) was the primary discharge diagnosis, were obtained from the National Emergency Department Sample (NEDS). RESULTS: Between 2006 and 2011, the frequency of constipation-related ED visits increased by 41.5%, from 497,034 visits to 703,391 visits, whereas the mean cost per patient rose by 56.4%, from $1,474 in 2006 to $2,306 in 2011. The aggregate national cost of constipation-related ED visits increased by 121.4%, from $732,886,977 in 2006 to $1,622,624,341 in 2011. All cost data were adjusted for inflation and reported in 2014 dollars. Infants (<1 year old) had the highest rate of constipation-related ED visits in both 2006 and 2011. The late elders (85+ years) had the second highest constipation-related ED visit rate in 2006; however, the 1- to 17-year-old age group experienced a 50.7% increase in constipation-related ED visit rate from 2006 to 2011 and had the second highest constipation-related ED visit rate in 2011. CONCLUSIONS: The frequency of and the associated costs of ED visits for constipation are significant and have increased notably from 2006 to 2011.

Complementary and Alternative Medicine Use Is Prevalent Among Patients with Gastrointestinal Diseases.

INTRODUCTION: Complementary and alternative medicine (CAM) use is reported to be higher among patients with irritable bowel syndrome and inflammatory bowel disease; however, demographic predictors and reasons for utilization for all GI conditions are less clear. AIM: To determine prevalence, predictors, and reasons for CAM use among all patients attending a gastrointestinal (GI) clinic in a single academic center. METHODS: Adults attending outpatient GI clinics at Beth Israel Deaconess Medical Center completed a questionnaire to assess CAM utilization as well as perceived benefits, harms, and costs of CAM therapy. Fisher's exact test was used to compare statistical differences between CAM and non-CAM users. RESULTS: Survey questionnaires were completed by 269 patients. Prevalence of CAM use was 44 % (95 % CI 38-50). Users were more likely to be female (81 vs. 56 %, p < 0.01) and dissatisfied with conventional treatment (22 vs. 8 %, p < 0.01). There was no significant difference in age, race, education, income, GI diagnosis, and duration of symptoms between the two groups. Users reported "wish to feel generally better" as main reason for utilization, and a majority of patients (62 %) experienced improved GI symptoms. Among patients who did not discuss CAM with their physicians (30 %), they cited physician failure to ask about CAM as the major reason (82 %). CONCLUSION: CAM is prevalent among patients attending a GI clinic, particularly among women and those who are dissatisfied with conventional therapies and "wish to feel better." Greater awareness and understanding of CAM among GI physicians is necessary.

Inpatient burden of constipation in the United States: an analysis of national trends in the United States from 1997 to 2010.

OBJECTIVES: Constipation is one of the most common outpatient diagnoses in primary care and gastroenterology clinics; however, there is limited data on the inpatient burden of constipation in the United States. The aim of this study was to evaluate inpatient admission rates, length of stay, and associated costs related to constipation from 1997 to 2010. METHODS: We analyzed the National Inpatient Sample Database for all patients in which constipation (ICD-9 codes: 564.0-564.09) was the principal discharge diagnosis from 1997 to 2010. The statistical significance of the difference in the number of hospital discharges, length of stay, and hospital costs over the study period was determined by utilizing the Spearman's coefficient to describe various trends. RESULTS: Between 1997 and 2010, the number of hospitalizations for patients with a primary discharge diagnosis of constipation increased from 21,190 patients to 48,450 (P<0.001, GoF test), whereas the mean length of hospital stay increased only slightly from 3.0 days to 3.1 days (b=0.008 (0.003-0.014); P=0.004). The mean charges per hospital discharge for constipation increased from $8869 in 1997 (adjusted for long-term inflation) to $17,518 in 2010 (b=745.4 (685.3-805.6); P<0.001)), whereas the total costs increased from $188,109,249 (adjusted for inflation) in 1997 to $851,713,263 in 2010. Although the elderly (65-84 years) accounted for the largest percentage of constipation discharges, patients in the 1-17 years age group had the highest frequency of constipation per 10,000 discharges. CONCLUSIONS: The number of inpatient discharges for constipation and associated costs has significantly increased between 1997 and 2010.
