Estimating Human Exposure to Rat Lungworm () on Hawai'i Island: A Pilot Study.

is a zoonotic, parasitic nematode causing angiostrongyliasis or rat lungworm disease. Clinical diagnosis in humans is currently confirmed by detection of parasite DNA in cerebrospinal fluid. This study estimated human exposure to in volunteer participants solicitated via public venues on east Hawai'i Island using blood-based tests.

Patient Perspectives in Comparing Hospitals for Childbirth: Insights from Hawai'i.

Childbirth is a national priority area for healthcare quality improvement. Patient perspectives are increasingly valued in healthcare, yet Asian American and Pacific Islander (AAPI) perspectives of healthcare quality are often understudied, particularly from individuals with limited English proficiency (LEP). Our study goal was to understand factors that consumers in Hawai'i, including AAPI and those with LEP, use to compare patient care in hospitals, especially for childbirth.

Gender Differences in the Rate of 30-Day Readmissions after Percutaneous Coronary Intervention for Acute Coronary Syndrome.

Background: It has been reported that women have higher 30-day readmission rates than men after acute coronary syndrome (ACS). However, readmission after percutaneous coronary intervention (PCI) for ACS is a distinct subset of patients in whom gender differences have not been adequately studied.

Methods: Hawaii statewide hospitalization data from 2010 to 2015 were assessed to compare gender differences in 30-day readmission rates among patients hospitalized with ACS who underwent PCI during the index hospitalization.

Community-acquired and hospital-acquired medication harm among older inpatients and impact of a state-wide medication management intervention.

Background: We previously reported reduction in the rate of hospitalisations with medication harm among older adults with our 'Pharm2Pharm' intervention, a pharmacist-led care transition and care coordination model focused on best practices in medication management. The objectives of the current study are to determine the extent to which medication harm among older inpatients is 'community acquired' versus 'hospital acquired' and to assess the effectiveness of the Pharm2Pharm model with each type.

Methods: After a 3-year baseline, six non-federal general acute care hospitals with 50 or more beds in Hawaii implemented Pharm2Pharm sequentially.

Understanding of Key Obstetric Quality Terminology by Asian and Pacific Islander Subgroups: Implications for Patient Engagement and Health Equity.

Introduction Comprehension of healthcare terminology across diverse populations is critical to patient education and engagement. Methods Women in Oahu, Hawai'i with a recent delivery were interviewed about their understanding of ten common obstetric terms. Health literacy was assessed by the rapid estimate of adult literacy in medicine (REALM).

Key Factors in Obstetric Delivery Decision-Making among Asian and Pacific Islander Women by English Proficiency.

Childbirth is the most common reason women are hospitalized in the United States. Understanding (1) how expectant mothers gather information to decide where to give birth, and (2) who helps make that decision, provides critical health communication and decision-making insights. Diverse Asian American and Pacific Islander (AA/PI) perspectives on such topics are understudied, particularly among those with limited English proficiency (LEP).

Thirty-Day Inpatient Readmissions for Asian American and Pacific Islander Subgroups Compared With Whites.

Asian and Pacific Islander (API) 30-day potentially preventable readmissions (PPRs) are understudied. Hawaii Health Information Corporation data from 2007-2012 statewide adult hospitalizations ( N = 495,910) were used to compare API subgroup and White PPRs. Eight percent of hospitalizations were PPRs.

Racial-ethnic Disparities in Postpartum Hemorrhage in Native Hawaiians, Pacific Islanders, and Asians.

The objective of this study was to assess racial-ethnic differences in the prevalence of postpartum hemorrhage (PPH) among Native Hawaiians and other Pacific Islanders (NHOPI), Asians, and Whites. We performed a retrospective study on statewide inpatient data for delivery hospitalizations in Hawai'i between January 1995 and December 2013. A total of 243,693 in-hospital delivery discharges (35.

Reductions in Medication-Related Hospitalizations in Older Adults with Medication Management by Hospital and Community Pharmacists: A Quasi-Experimental Study.

Objectives: To evaluate the association between a system of medication management services provided by specially trained hospital and community pharmacists (Pharm2Pharm) and rates and costs of medication-related hospitalization in older adults.

Design: Quasi-experimental interrupted time series design comparing intervention and nonintervention hospitals using a mixed-effects analysis that modeled the intervention as a time-dependent variable.

Setting: Sequential implementation of Pharm2Pharm at six general nonfederal acute care hospitals in Hawaii with more than 50 beds in 2013 and 2014.

Ethnic Comparison of 30-Day Potentially Preventable Readmissions After Stroke in Hawaii.

Background And Purpose: Ethnic disparities in readmission after stroke have been inadequately studied. We sought to compare potentially preventable readmissions (PPR) among a multiethnic population in Hawaii.

Methods: Hospitalization data in Hawaii from 2007 to 2012 were assessed to compare ethnic differences in 30-day PPR after stroke-related hospitalizations.

Health Disparities in Native Hawaiians and Other Pacific Islanders Following Hysterectomy for Endometrial Cancer.

The current study was undertaken to assess disparities in 5 year admission rates and mortality following hysterectomy for endometrial cancer in the State of Hawai'i. Data from the Hawai'i Health Information Corporation was utilized to determine five-year admission rates and overall mortality. Native Hawaiian and Other Pacific Islander (NHOPI) patients were compared to non-NHOPI patients for the period January 1, 2007 to December 31, 2013.

Comparison of Primary Cesarean Delivery Rates Among Low-Risk Women in Urban and Rural Hospitals in Hawaii.

Objective The purpose of this study was to examine primary cesarean delivery rates among women with low risk pregnancies in urban and rural hospitals in Hawaii. Methods This is a retrospective study of all low-risk women (term, vertex, singleton) who had a primary cesarean delivery in any Hawaii hospital from 2010 to 2011 using a statewide health information database. Hospitals were divided into two categories: rural and urban.

Differences in severity at admission for heart failure between rural and urban patients: the value of adding laboratory results to administrative data.

Background: Rural/urban variations in admissions for heart failure may be influenced by severity at hospital presentation and local practice patterns. Laboratory data reflect clinical severity and guide hospital admission decisions and treatment for heart failure, a costly chronic illness and a leading cause of hospitalization among the elderly. Our main objective was to examine the role of laboratory test results in measuring disease severity at the time of admission for inpatients who reside in rural and urban areas.

Racial/Ethnic Disparities in the Association Between Preeclampsia Risk Factors and Preeclampsia Among Women Residing in Hawaii.

Objective To assess differences in the rates of preeclampsia among a multiethnic population in Hawaii. Methods We performed a retrospective study on statewide inpatient data for delivery hospitalizations in Hawaii between January 1995 and December 2013. Multivariable logistic regression was used to assess the impact of maternal race/ethnicity on the rates of preeclampsia after adjusting for age, multiple gestation, multiparity, chronic hypertension, pregestational diabetes, obesity and smoking.

Inpatient Hospitalization Costs: A Comparative Study of Micronesians, Native Hawaiians, Japanese, and Whites in Hawai'i.

Considerable interest exists in health care costs for the growing Micronesian population in the United States (US) due to their significant health care needs, poor average socioeconomic status, and unique immigration status, which impacts their access to public health care coverage. Using Hawai'i statewide impatient data from 2010 to 2012 for Micronesians, whites, Japanese, and Native Hawaiians (N = 162,152 hospitalizations), we compared inpatient hospital costs across racial/ethnic groups using multivariable models including age, gender, payer, residence location, and severity of illness (SOI). We also examined total inpatient hospital costs of Micronesians generally and for Medicaid specifically.

Younger and Sicker: Comparing Micronesians to Other Ethnicities in Hawaii.

Objectives: We compared the age at admission and the severity of illness of hospitalized Micronesians with 3 other racial/ethnic groups in Hawaii.

Methods: With Hawaii Health Information Corporation inpatient data, we determined the age at admission and the severity of illness for 162,152 adult, non-pregnancy-related hospital discharges in Hawaii from 2010 to 2012. We performed multivariable linear regression analyses within major disease categories by racial/ethnic group.

Racial/Ethnic-Specific Reference Intervals for Common Laboratory Tests: A Comparison among Asians, Blacks, Hispanics, and White.

Reference intervals (RIs) for common clinical laboratory tests are usually not developed separately for different subpopulations. The aim of this study was to investigate racial/ethnic differences in RIs of common biochemical and hematological laboratory tests using the National Health and Nutrition Examination Survey (NHANES) 2011-2012 data. This current study included 3,077 participants aged 18-65 years who reported their health status as "Excellent," "Very good," or "Good," with known race/ethnicity as white, black, Hispanic, or Asian.

Association between sugar cane burning and acute respiratory illness on the island of Maui.

Background: Sugar cane harvesting by burning on Maui island is an environmental health issue due to respiratory effects of smoke. Volcanic smog ("vog") from an active volcano on a neighboring island periodically blankets Maui and could confound a study of cane smoke's effects since cane burning is not allowed on vog days. This study examines the association between cane burning and emergency department (ED) visits, hospital admissions, and prescription fills for acute respiratory illnesses.

Maternal risk factors and perinatal outcomes among pacific islander groups in Hawaii: a retrospective cohort study using statewide hospital data.

Background: Studies suggest Pacific Islander women have disparate rates of preterm birth, primary cesarean delivery, preeclampsia, gestational diabetes, and low birthweight infants. However, data is limited. In order to improve the health of Pacific Islanders, it is essential to better understand differences in obstetric outcomes in this diverse population

Methods: This study compared perinatal outcomes between Pacific Islander (9,646) and White (n = 5,510) women who delivered a singleton liveborn in any Hawaii hospital from January 2010 to December 2011 using the Hawaii Health Information Corporation (HHIC) database.

The Burden of Diagnosed and Undiagnosed Diabetes in Native Hawaiian and Asian American Hospitalized Patients.

Aims: Little is known about diabetes in hospitalized Native Hawaiians and Asian Americans. We determined the burden of diabetes (both diagnosed and undiagnosed) among hospitalized Native Hawaiian, Asian (Filipino, Chinese, Japanese), and White patients.

Methods: Diagnosed diabetes was determined from discharge data from a major medical center in Hawai'i during 2007-2008.

Disparities in Potentially Preventable Hospitalizations for Chronic Conditions Among Korean Americans, Hawaii, 2010-2012.

Introduction: Korean Americans are a growing but understudied population group in the United States. High rates of potentially preventable hospitalizations suggest that primary care is underutilized. We compared preventable hospitalizations for chronic conditions in aggregate and for congestive heart failure (CHF) for Korean Americans and whites in Hawaii.

Maternal language and adverse birth outcomes in a statewide analysis.

Limited English proficiency is associated with disparities across diverse health outcomes. However, evidence regarding adverse birth outcomes across languages is limited, particularly among U.S.

Length of Stay and Deaths in Diabetes-Related Preventable Hospitalizations Among Asian American, Pacific Islander, and White Older Adults on Medicare, Hawai'i, December 2006-December 2010.

Introduction: The objective of this study was to compare in-hospital deaths and length of stays for diabetes-related preventable hospitalizations (D-RPHs) in Hawai'i for Asian American, Pacific Islander, and white Medicare recipients aged 65 years or older.

Methods: We considered all hospitalizations of older (>65 years) Japanese, Chinese, Native Hawaiians, Filipinos, and whites living in Hawai'i with Medicare as the primary insurer from December 2006 through December 2010 (n = 127,079). We used International Classification of Diseases - 9th Revision (ICD-9) codes to identify D-RPHs as defined by the Agency for Healthcare Research and Quality.
