BACKGROUND: Prior studies report safety and effectiveness of laparoscopic colectomy in older patients. The study aimed to examine the impact of laparoscopic colectomy on 30-day readmissions, discharge destination, hospital length of stay, and cost in younger (19-65 years) and older adults (>65 years). MATERIALS AND METHODS: We used the nationwide readmission database from 2013 to study adults undergoing elective colectomy. The outcomes were 30-day readmissions, discharge destination for the index hospitalization (routine, skilled nursing facility [SNF]/intermediate care facility [ICF], home healthcare), length of stay, and cost...

BACKGROUND: Maternal critical illness occurs in 1.2 to 4.7 of every 1000 live births in the United States and approximately 1 in 100 women who become critically ill will die. Patient characteristics and comorbid conditions are commonly summarized as an index or score for the purpose of predicting the likelihood of dying; however, most such indices have arisen from non-pregnant patient populations. We sought to systematically review comorbidity indices used in health administrative datasets of pregnant women, in order to critically appraise their measurement properties and recommend optimal tools for clinicians and maternal health researchers...

INTRODUCTION: The International Cancer Benchmarking Partnership (ICBP) identified significant international differences in lung cancer survival. Differing levels of comorbid disease across ICBP countries has been suggested as a potential explanation of this variation but, to date, no studies have quantified its impact. This study investigated whether comparable, robust comorbidity scores can be derived from the different routine population-based cancer data sets available in the ICBP jurisdictions and, if so, use them to quantify international variation in comorbidity and determine its influence on outcome...

OBJECTIVES: The outcomes of critically ill patients who undergo interhospital transfer are not well understood. Physicians assume that patients who undergo interhospital transfer will receive more advanced care that may translate into decreased morbidity or mortality relative to a similar patient who is not transferred. However, there is little empirical evidence to support this assumption. We examined country-level U.S. data from the Nationwide Readmissions Database to examine whether, in mechanically ventilated patients with sepsis, interhospital transfer is associated with a mortality benefit...

BACKGROUND: Identifying patients at highest risk for a complex perioperative course following total hip arthroplasty (THA) is more important than ever in order to educate patients, optimize outcomes, and to minimize cost and length of stay. There are no known studies comparing the clinically relevant discriminative ability of 3 commonly used comorbidity indices for adverse outcomes following THA: Elixhauser Comorbidity Measure (ECM), the Charlson Comorbidity Index (CCI), and the modified Frailty Index (mFI)...

BACKGROUND: Although there is a general perception that, as the older population grows in number, more are undergoing surgery, there are few data on trends in major resections for cancer and short-term outcomes in this group. METHODS: The Nationwide Inpatient Sample was (NIS) used to estimate the national trends of major upper abdominal resections (esophagus, stomach, liver, pancreas) for cancer in octogenarians (aged ≥80 years) from 2001 to 2011. Resection rates performed per year were incidence-adjusted within this age group for each cancer type as determined by the NIS database...

BACKGROUND: Hospitalization is associated with negative clinical effects that last beyond discharge. This study aimed to determine whether hospitalization in the year before major oncologic surgery is associated with adverse outcomes. METHODS: Patients 18 years of age or older with stomach, pancreas, colon, or rectal cancer who underwent resection in California and New York (2008-2010) were included in the study. Patients with hospitalization in the year prior to oncologic resection (HYPOR) were identified...

Few studies have examined rates and causes of short-term readmissions among adults across age and insurance types. We compared rates, characteristics, and costs of 30-day readmission after all-cause hospitalizations across insurance types in the US. We retrospectively evaluated alive patients ≥18 years old, discharged for any cause, 1/1/13-11/31/13, 2006 non-federal hospitals in 21 states in the Nationwide Readmissions Database. The primary stratification variable of interest was primary insurance. Comorbid conditions were assessed based on Elixhauser comorbidities, as defined by administrative billing codes...

BACKGROUND AND PURPOSE: It is uncertain whether previous ischemic stroke within 3 months of receiving intravenous thrombolysis (tPA [tissue-type plasminogen activator]) for acute ischemic stroke (AIS) is associated with an increased risk of adverse outcomes. METHODS: Using administrative claims data, we identified adults with AIS who received intravenous tPA at California, New York, and Florida hospitals from 2005 to 2013. Our primary outcome was intracerebral hemorrhage, and our secondary outcomes were unfavorable discharge disposition and inpatient mortality...

BACKGROUND: There is considerable debate regarding the ideal agent for venous thromboembolism (VTE) prophylaxis after TKA. Numerous studies and meta-analyses have yet to provide a clear answer and often omit one or more of the commonly used agents such as aspirin, warfarin, enoxaparin, and factor Xa inhibitors. QUESTIONS/PURPOSES: Using a large database analysis, we asked: (1) What are the differences in VTE incidence in primary TKA after administration of aspirin, warfarin, enoxaparin, or factor Xa inhibitors? (2) What are the differences in bleeding risk among these four agents? (3) How has use of these agents changed with time? METHODS: We queried a combined Humana and Medicare database between 2007 and Quarter 1 of 2016, and identified all primary TKAs performed using ICD-9 and Current Procedural Terminology codes...
