Advantages
Our approach using NLP offers advantages over traditional methods of cohort identification, such as structured data or keyword searching. For many of our prior queries, ICD-9/10 codes, CPT codes, or e-codes do not exist. With this approach and using software and support from our team, users at BCH have completed many successful research projects:
| Publication/project | Patient cohort | Case fraction missed using ICD-9/10 |
|---|---|---|
| Hennely et al. | Penetrating palate injury | 83% |
| Aprahamian et al. | Glass thermometer injury | ICD-9/10 does not exist |
| Deanehan et al | First time knee monoarthritis | 26% |
| Kimia et al. | First complex febrile seizure | 48% |
| Rudloe et al. | Peri-orbital cellulitis | 33% |
| Nigrovic et al | Lumbar puncture, excluding VP shunt and diabetes | ICD-9/10 does not exist |
| Hodges et al. | Dacryocystitis | 54% |
| Hudgins et al. | Lymphangitic streaking | 69% |
| Miller et al | Misplaced ET tubes after intubation | ICD-9/10 does not exist |
| Lessenich et al | Patients evaluated for intussusception | 41% |
| Capraro et al. | Unapproved abbreviations in text | ICD-9/10 does not exist |
