Abstract

Background Racial and ethnic disparities in opioid prescribing in the emergency department (ED) are well described, yet the influence of socioeconomic status (SES) remains unclear. Objectives (1) To examine the effect of neighborhood SES on the prescribing of opioids for moderate to severe pain; and (2) to determine if racial disparities in opioid prescribing persist after accounting for SES. Design We used cross-sectional data from the National Hospital Ambulatory Medical Care Survey between 2006 and 2009 to examine the prescribing of opioids to patients presenting with moderate to severe pain (184 million visits). We used logistic regression to examine the association between the prescribing of opioids, SES, and race. Models were adjusted for age, sex, pain-level, injury-status, frequency of emergency visits, hospital type, and region. Main measures Our primary outcome measure was whether an opioid was prescribed during a visit for moderate to severe pain. SES was determined based on income, percent poverty, and educational level within a patient's zip code. Results Opioids were prescribed more frequently at visits from patients of the highest SES quartile compared to patients in the lowest quartile, including percent poverty (49.0 % vs. 39.4 %, P<0.001), household income (47.3 % vs. 40.7 %, P<0.001), and educational level (46.3 % vs. 42.5 %, P=0.01). Black patients were prescribed opioids less frequently than white patients across all measures of SES. In adjusted models, black patients (AOR 0.73; 95 % CI 0.66–0.81) and patients from poorer areas (AOR 0.76; 95 % CI 0.68–0.86) were less likely to receive opioids after accounting for pain-level, age, injury-status, and other covariates. Conclusions Patients presenting to emergency departments from lower SES regions were less likely to receive opioids for equivalent levels of pain than those from more affluent areas. Black and Hispanic patients were also less likely to receive opioids for equivalent levels of pain than whites, independent of SES.

TL;DR

In NHAMCS 2006–2009, ED patients with moderate-to-severe pain from lower-SES neighborhoods were less likely to receive opioids than those from more affluent neighborhoods. Black and Hispanic patients were also less likely to receive opioids than white and non-Hispanic patients, and these disparities persisted after adjustment for neighborhood SES.

Key findings

  • Opioid prescribing was lower in the lowest vs highest SES quartiles: poverty 39.4% vs 49.0% (P<0.001), income 40.7% vs 47.3% (P<0.001), and education 42.5% vs 46.3% (P=0.01).
  • In adjusted models, patients in high-poverty areas (>20% poverty) were less likely to receive opioids than those in low-poverty areas (<5%): AOR 0.76, 95% CI 0.68–0.84.
  • Black patients received opioids less often than white patients (38.7% vs 46.4%, P<0.001); adjusted models accounting for SES showed lower odds (poverty AOR 0.73, 95% CI 0.67–0.80; income AOR 0.71, 95% CI 0.65–0.78; education AOR 0.69, 95% CI 0.63–0.76).
  • Hispanic patients received opioids less often than non-Hispanic patients (40.4% vs 44.9%, P<0.001); adjusted AORs were 0.83 (0.75–0.91) for poverty, 0.83 (0.74–0.88) for income, and 0.80 (0.73–0.88) for education. No trend in opioid prescribing by race was found from 2006 to 2009.

Methods

  • Cross-sectional analysis of National Hospital Ambulatory Medical Care Survey (NHAMCS) data from 2006–2009, including adults ≥18 presenting to EDs with moderate-to-severe pain; weighted to national estimates (abstract reports 184 million visits).
  • Primary outcome: whether an opioid was prescribed. Neighborhood SES was measured by zip-code quartiles for poverty, median household income, and education; race was white/black/other and ethnicity Hispanic/non-Hispanic.
  • Logistic regression models, weighted for complex sampling, with separate models for each SES measure and adjustment for age, sex, pain severity, injury status, prior ED visits, hospital type, region, and metropolitan status.

Limitations

  • Stated: SES was defined only by five-digit zip code, so patient-level SES beyond neighborhood quartiles was unavailable; sample size did not allow examining Asian or other racial groups separately; quantity and strength of opioids were not available; clinician race/ethnicity, institutional/prescriber factors, and use of testing or prescription monitoring were not accounted for.
  • Stated: SES was missing for approximately 5.7% of visits, and those visits were excluded.
  • Evident: the cross-sectional observational design cannot establish causality and may leave residual confounding.

  • The paper relies on this without support.

    The influence of neighborhood socioeconomic status on opioid prescribing for pain in the emergency department is unknown.

    “Although racial and ethnic disparities in opioid prescribing in the emergency departments remains steady, the broader influence of socioeconomic status (SES) on the treatment of patients' pain is unknown.”
  • The paper relies on this without support.

    Whether differences in socioeconomic status explain some of the racial and ethnic disparities in opioid prescribing in the emergency setting is unknown.

    “Additionally, it is unknown whether differences in SES may explain some of the racial and ethnic disparities previously observed in opioid prescribing in the emergency setting.”

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Abstract uses the unadjusted confidence interval for black patients

    Minor

    The abstract labels 0.73 (0.66-0.81) as an adjusted estimate. Table 2 places that estimate and interval in the unadjusted odds-ratio column; its adjusted poverty-model estimate is 0.73 (0.67-0.80).

  • Reported opioid-prescribing visits exceed the total unweighted sample

    Minor

    The Results state that opioids were prescribed in 50,264 visits, but Table 1 gives 50,236 as the total unweighted sample size. The number of opioid-prescribing visits cannot exceed the total number of visits.

  • Education categories overlap

    Minor

    The education ranges 16.67-31.68% and 12.84-19.66% overlap from 16.67% through 19.66%, although they are presented as separate categories.

  • Results assign other-race adjusted odds ratios to black patients

    Minor

    The three adjusted odds ratios reported for black patients in the Results are the values in Table 2's "Other" race row. The table gives black patients adjusted odds ratios of 0.73, 0.71, and 0.69 for the poverty, income, and education models, respectively.

  • Abstract's confidence interval for poorer areas differs from the adjusted poverty result

    Minor

    The abstract reports an adjusted odds ratio of 0.76 with a 0.68-0.86 confidence interval for poorer areas. The Results give the adjusted high-poverty comparison as 0.76 with a 0.68-0.84 interval; 0.76 (0.68-0.86) appears in Table 2 as an unadjusted income comparison.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
