Narrative synthesis #

This is the exposure-contrast claim (LEP / language-discordant patients vs English-proficient patients), distinct from the intervention-contrast claims that providing concordance (concordant providers, interpreters, culturally tailored education) improves adherence. The clearest signal comes from pediatric audiology, where data-logged hearing-aid wear time was dramatically lower for LEP families (1.30 vs 5.19 hr/day) and near-nonuse was concentrated in the LEP group — a gap not explained by hearing-loss severity. Lower LEP uptake of adherence-supporting remote-refill systems points the same direction. The signal is not uniform, however: in HIV care, LEP adults were actually more likely to be prescribed ART and showed no adherence difference (Padilla), and the remote-refill gap was confined to the English-only Internet channel rather than telephone refills. Because the directional (worse-adherence) finding sits in tension with the "LEP is not necessarily worse" claim, this claim is wired as opposing it so the topology surfaces the disagreement for expert adjudication.

"Specifically, the daily mean hearing aid wear time for the children from English-proficient families was 5.19 hr (SD = 3.98) and the mean daily wear time for the children from families with limited English proficiency was 1.30 hr (SD = 1.93)." (Brigham, 2024, p. 324)
