DGPNSD had no further role in study design; in the collection; analysis and interpretation of data; in the writing of the report; or in the decision to submit the paper for publication.Aims: Alcohol use disorders (AUD) have been associated with an increased risk of unplanned hospital readmissions (URA). We analyzed in a sample of 87 Spanish Hospitals if surgical patients with AUD had a higher risk of URA and if among patients with URA, those with AUD had an excess length of hospital stay, higher hospital expenses and increased risk of mortality. Method: We analyzed data of patients who underwent surgical operations during the period between 2008 and 2010. URA was defined as unplanned readmissions during the first 30 days after hospital departure. The primary outcome was risk of URA in patients with AUD. Secondary outcomes were mortality, excess length of stay and over expenditure. Results: A total of 2,076,958 patients who underwent surgical operations were identified: 68,135 (3.3%) had AUD, and 62,045 (3.0%) had at least one URA. Among patients with AUD 4212 (6.2%) had at least one URA and among patients without AUD 57,833 (2.9%) had at least one URA. Multivariable analysis demonstrated that AUD was an independent predictor of developing URA (Odds ratio: 1.56; 95% CI: 1.50–1.62). Among surgical patients with URA, those with AUD had longer lengths of hospital stay (2.9 days longer), higher hospital costs (2885.8 Euros or 3858.3 US Dollars), higher risk of death (OR: 2.16, 95% CI: 1.92–2.44) and higher attributable mortality (11.2%). Conclusions: Among surgical patients, AUD increase the risk of URA, and among patients with URA, AUD heighten the risk of in-hospital death, and cause longer hospital stays and over expenditures.enAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Alcohol use disordersUnplanned hospital readmissionsMortalityProlonged hospital stayExcessive costsHumansLength of stayPatient readmissionAlcoholismHealth expendituresHospital cortalityHospital costsOdds ratioHospitalsresearch article24529967restricted accessAlcoholismoCostos de hospitalGastos en saludHospitalesHumanosMortalidad hospitalariaReadmisión del paciente10.1016/j.drugalcdep.2014.01.009
