The Impact of the Affordable Care Act Insurance Expansions on Opioid-Related Emergency Department Visits.
The authors leveraged ACA coverage expansions, including Medicaid expansion and Marketplaces, to study the impact of health insurance on opioid-related emergency department (ED) visits. They used ZIP-code–level ED utilization data from HCUP’s State Inpatient Databases (SID) and State Emergency Department Databases (SEDD) for 29 states. They found evidence of a dose-response relationship between pre-ACA uninsured and changes in ED visit rates in both expansion and non-expansion states: areas with higher uninsured rates prior to ACA saw larger reductions in opioid-related ED visits after the ACA took effect. The authors concluded that these findings suggest that increased insurance coverage may to help mitigate the opioid crisis.

Neonatal abstinence syndrome and maternal opioid-related diagnoses: analysis of ICD-10-CM transition, 2013-2017.
Researchers sought to evaluate whether the transition from ICD-9-CM to ICD-10-CM may have affected surveillance on rates of neonatal abstinence syndrome (NAS), maternal opioid use disorder (OUD), and opioid-related diagnoses. Using HCUP data, they found that the ICD-10-CM transition did not appear to affect NAS. However, coding of maternal OUD alone may not capture the same population across the transition, potentially confounding the interpretation of trend data spanning this time period.

Neonatal abstinence syndrome and maternal opioid-Related diagnoses in the US, 2010-2017.
This study analyzed trends in neonatal abstinence syndrome (NAS) and maternal opioid-Related diagnosis (MOD) in the United States from 2010 to 2017. A cross-sectional analysis was done of the HCUP National Inpatient Sample and State Inpatient Database from 2010 through 2017. Diagnoses of NAS and MOD were found using the ICD-10, CM codes. Significant increases occurred in rates of NAS, from 4.0 to 7.3 per birth hospitalizations and MOD, from 3.5 to 8.2 per 1000 delivery hospitalizations. A census of 47 state databases in 2017 found a large range of NAS rates – from 1.3 per 1000 birth hospitalizations in Nebraska to 53.5 per 1000 hospitalizations in West Virginia with the same ranges found for MOD rates. In all states except Nebraska and Vermont which only had significant MOD increases, NAS and MOD rates rose significantly from 2010 to 2017.

Disparities in United States hospitalizations for serious infections in patients with and without opioid use disorder: a nationwide observational study.
This study examined the differences in patients with and without opioid use disorder (OUD) who were hospitalized for serious infections focusing on infective endocarditis, epidural abscess, septic arthritis or osteomyelitis. The authors used the 2016 National Inpatient Sample to examine differences in length of stay (LOS), discharge disposition, and charges. Patients with OUD had a lower probability of discharge at any given LOS, and lower odds of discharge to home with higher odds of discharge to a post-acute care facility. There were no significant differences in average total hospital charges.

Multilevel risk factors for hospital readmission among patients with opioid use disorder in selected US States: role of socioeconomic characteristics of patients and their community.
This study examined the association of socioeconomic characteristics of individuals hospitalized with a principal diagnosis of opioid use disorder and their all-cause 30-day readmission risks. Discharge data from the 2014 HCUP Survey was used and was linked to community and hospital characteristics using data from HRSA and the American Hospital Association. Medicare is associated with the highest readmission risk followed by Medicaid covered patients. Self-pay or covered by other payers had a similar risk to private insurance coverage. Urban patients also had a higher readmission rate than rural patients.

Readmissions following inpatient treatment for opioid-related conditions.
This study analyzed the relationship between hospital admission for inpatient drug detoxification and/or rehabilitation services and subsequent opioid-related readmission. The study used hospital inpatient discharge and emergency department visit data from the AHRQ Healthcare Cost and Utilization Project (HCUP) survey. The sample consisted of 329,037 patients from seven states with an opioid-related index hospitalization from March 2010 to September 2013. A relatively small percentage (19.4%) of patients received treatment for drug use during their hospital stay. Those patients that did receive treatment had a lower 90-day readmission rate than those patients who did not.

State variation in opioid treatment policies and opioid-related hospital readmissions.
In this study, the investigators used 2013-2015 hospital inpatient discharge data from 13 states from the Agency for Healthcare Research and Quality Healthcare Cost and Utilization Project to examine the relationship between state opioid treatment policies and 90-day opioid-related readmissions after a stay involving an opioid diagnosis. The concluded that differences in index hospitalization rates suggested that states with opioid treatment policies had a higher level of need for opioid-related intervention, which also may account for higher rates of readmission.

Trends in opioid-related inpatient stays shifted after the US transitioned to ICD-10-CM diagnosis coding in 2015.
This study examines how trend analyses of inpatient stays involving opioid diagnoses were affected by the transition to ICD-10-CM. It found a sharp increase in opioid-related stays overall during the transition to ICD-10-CM. This may indicate that the new classification system is capturing stays that were missed by ICD-9-CM data.
