The potential lost hospital income from miscoded emergency department boarders in Ireland.

BACKGROUND: Emergency department (ED) boarders, namely patients who have been admitted under an in-patient service but remain on a trolley in the ED, have long been a problem in the Irish healthcare system. METHODS: We conducted a retrospective analysis of all ED boarders in Cork University Hospital (CUH) for a 6-month period from January to July 2011. Data were obtained from the Hospital In-Patient Enquiry Office (HIPE). The income generated by the hospital for a subset of these patients (January and February attendances) was obtained from the Finance Office in the hospital, based on diagnoses as recorded on the HIPE system. A convenience sample of two-thirds of the 39 acute hospitals nationally was surveyed to ascertain whether ED boarders were coded by individual HIPE offices as hospital in-patients or as ED attendees. RESULTS: A total of 806 patients were admitted to an in-patient service from January to July 2011 in CUH and subsequently discharged, having completed their entire stay in the ED. The income generated by a sub-sample of 228 patients (January and February ED boarders) was determined. The hospital was remunerated by 685,111 for these patients, i.e. an average income of 3,098 per patient. Only 8 hospitals of the 27 surveyed hospitals coded overnight ED Boarders as in-patients and were thus able to request income for these patients appropriately. CONCLUSION: Discrepancies in coding of ED boarders may result in significant revenue losses for certain hospitals.
