  "abstract": "Rationale We previously found that patients of South-Asian and Black ethnicities were less likely to receive an explanatory diagnosis after presentation with breathlessness. As part of further exploration of the underlying reasons for these findings, we investigated the influence of ethnicity on recorded investigations after the point of first presentation with breathlessnessMethods Using the Clinical Practice Research Datalink (CPRD) GOLD database, linked with Hospital Episode Statistics, we identified adults with a first-recorded presentation (index date) with breathlessness between 2007 and 2017. The proportions of patients with a recorded code for possible investigations recommended by NHS England after presentation with breathlessness, within 6 months and 24 months of the index date, were identified. The six most frequently recorded investigations across the whole cohort were identified, and logistic regression was used to estimate adjusted odds ratios for receiving each of these across different ethnic groups, during the above timeframes. All models were adjusted for age, sex, index of multiple deprivation (IMD) quintile and presence of underlying multiple long-term conditions (MLTC) (defined as 2 or more long-term conditions).Results We included 88,857 patients, of whom 3,336 were of South-Asian ethnicity and 1,506 of Black ethnicity. Patients with ethnicity coding of Mixed/Other/Unknown (n=12,512) were excluded as we were unable to ascertain their ethnic group with available data. Blood haemoglobin (Hb)(47%), chest x-ray (26%), electrocardiogram (ECG) (20%), spirometry (11%), pulse oximetry (7%), and echocardiogram (7%) were the most frequently recorded investigations within both 6 months, and 24 months of the index date. Compared to patients of White ethnicity, patients of South-Asian and Black ethnicities were significantly more likely to be investigated for Hb. However, both groups were significantly less likely to undergo spirometry or pulse oximetry, compared to patients of White ethnicity ( figure 1).Abstract P123 Figure 1Conclusion We observed significant differences in likelihood of some investigations across different ethnic groups, notably a significantly increased likelihood of Hb in patients of South-Asian and Black ethnicities but a significantly lower likelihood of spirometry and pulse oximetry. Whether these findings represent an inequity along the investigative pathway after presentation with breathlessness, or differences in clinical presentation, warrants further exploration.",
