Spanish NEPL was not associated with increased odds of emergency surgery (OR 0.80, P=0.077) for diverticulitis

Description #

In the language-subgroup multivariable analysis, Spanish-speaking NEPL patients did NOT have significantly different odds of emergency versus elective surgery compared to EPL patients (OR 0.80; 95% CI 0.63–1.03; P = 0.077) — a null result whose confidence interval crosses 1 (Table 3 subgroup analysis, reported in text). The point estimate is below 1 (numerically lower odds), but not statistically significant. This contrasts with the significantly elevated odds seen for non-Spanish NEPL patients.

"More specifically, while Spanish NEPL patients had no significantly different odds of emergency surgery (OR 0.80; 95% CI 0.63-1.03; P = 0.077) compared to EPL patients, patients with non-Spanish NEPL had significantly increased odds of emergency surgery (OR 2.29; 95% CI 1.78-2.97; P <0.001) compared to patients with EPL." (Maurer, 2021, p. 645)

Methods Context #

What? #ⓘ

The observable: emergency (urgent/emergent) versus elective surgical admission type, with primary language sub-categorized into Spanish NEPL versus EPL (reference).

"Primary language was dichotomized into NEPL versus English primary language (EPL), and further sub-categorized into Spanish versus non-Spanish NEPL." (Maurer, 2021, p. 644)

How? #ⓘ

Multivariable logistic regression with the same covariate set (age, sex, insurance, income quartile, data year, CCI), estimating odds of emergency surgery for Spanish NEPL relative to EPL patients.

"All models were controlled for age, sex, insurance status, median household income quartile, data year, and Charlson Comorbidity Index (CCI)18 in multivariable regression models." (Maurer, 2021, p. 645)

Who? #ⓘ

The 300 Spanish-primary-language patients (of 592 NEPL) among 9,453 adult diverticulitis surgery patients in the New Jersey State Inpatient Database, compared with the EPL reference group.

"Among NEPL patients, 300 (51%) had Spanish as primary language and 292 (49%) had another non-Spanish primary language." (Maurer, 2021, p. 643)

Other Notes #

Null result — this opposes a blanket claim that all NEPL raises emergency-surgery odds and supports the heterogeneity claim (effect concentrated in non-Spanish speakers). The authors attribute the Spanish-group null to greater availability of Spanish-language services in New Jersey, but also caution they did not power granular Spanish subgroup analyses. Unadjusted descriptive rates (Table 2) show 51.7% of Spanish NEPL versus 69.2% of non-Spanish NEPL underwent emergency surgery.

Caveats #

• Single-state New Jersey inpatient data limits generalizability of the diverticulitis language findings The analysis draws on only the New Jersey State Inpatient Database, chosen because primary-language coding was not uniformly available across other states' SIDs. Because state-by-state policy (including availability of language services) can influence access and outcomes, the findings — and especially the Spanish-versus-non-Spanish contrast, which the authors tie to New Jersey's large Spanish-speaking population and services — may not transfer to other states or settings.
• Retrospective single-database diverticulitis study precludes causal inference and leaves residual confounding The study is a retrospective analysis of a single administrative claims database, so it can establish association but not causation between non-English primary language and emergency surgery. Residual confounding is likely on two additional counts the authors flag: income was available only as an ecological, neighborhood-level (FIPS) measure rather than individual income, and the State Inpatient Database offers no longitudinal patient linkage, so prior diverticulitis admissions and the true denominator of overall disease burden per patient are unknown. Together these limit adjustment for socioeconomic status and disease chronicity, so the adjusted odds ratios should be read as associational estimates that may retain uncontrolled confounding.
