Healthcare utilization in medical intensive care unit survivors with alcohol withdrawal.

ABSTRACT: Rehospitalization is an important and costly outcome that occurs commonly in several diseases encountered in the medical intensive care unit (ICU). Although alcohol use disorders are present in 40% of ICU survivors and alcohol withdrawal is the most common alcohol-related reason for admission to an ICU, rates and predictors of rehospitalization have not been previously reported in this population.We conducted a retrospective cohort study of medical ICU survivors with a primary or secondary discharge diagnosis of alcohol withdrawal using 2 administrative databases. The primary outcome was time to rehospitalization or death. Secondary outcomes included time to first emergency department or urgent care clinic visit in the subset of ICU survivors who were not rehospitalized. Cox proportional hazard models were adjusted for age, gender, race, homelessness, smoking, and payer source.Of 1,178 patients discharged from the medical ICU over the study period, 468 (40%) were readmitted to the hospital and 54 (4%) died within 1 year. Schizophrenia (hazard ratio 2.23, 95% CI 1.57, 3.34, p < 0.001), anxiety disorder (hazard ratio 2.04, 95% CI 1.30, 3.32, p < 0.01), depression (hazard ratio 1.62, 95% CI 1.05, 2.40, p = 0.03), and Deyo comorbidity score ?3 (hazard ratio 1.43, 95% CI 1.09, 1.89, p = 0.01) were significant predictors of time to death or first rehospitalization. Bipolar disorder was associated with time to first emergency department or urgent care clinic visit (hazard ratio 2.03, 95% CI 1.24, 3.62, p < 0.01) in the 656 patients who were alive and not rehospitalized within 1 year.The presence of a psychiatric comorbidity is a significant predictor of multiple measures of unplanned healthcare utilization in medical ICU survivors with a primary or secondary discharge diagnosis of alcohol withdrawal. This finding highlights the potential importance of targeting longitudinal multidisciplinary care to patients with a dual diagnosis.

Project description:Cardiac rehabilitation (CR) is associated with decreased mortality and rehospitalization rates for patients with a variety of cardiac conditions. Although CR referral rates for STEMI patients have improved, rates for heart failure have remained low. Many of these patients are admitted to the cardiac intensive care unit (CICU). However, it is unknown how often CICU survivors qualify for cardiac rehabilitation, how often they are referred, and why eligible patients are not referred. This is a retrospective single-center study of 417 consecutive patients admitted to CICU for >48 hours from March 30, 2016 to March 30, 2017. We excluded patients with in-hospital mortality or those discharged AMA, to hospice or transferred. Chart abstraction was used to determine CR indications based on known American College of Cardiology/American Heart Association guidelines. If CR was indicated, medical records through September 2017 were reviewed to determine both referral and participation rates. In the absence of a referral, medical records were reviewed for potential barriers. A total of 296 CICU survivors were identified upon discharge with 185 (63%) having guideline-directed indications for CR referral. The most common indications were heart failure with reduced ejection fraction (HFrEF, 38%), cardiothoracic surgery (26%), and STEMI (23%). Upon discharge, only 30% of patients were referred to CR. The referral rate increased by 33% to 63% by 18 months postdischarge. CR referrals were most frequently placed following STEMI (91%), NSTEMI (80%), and postpercutaneous coronary intervention (80%). Only 35% of HFrEF discharges were referred to CR. Of patients not referred to CR, no explanation for a lack of referral was documented 87% of the time. In conclusion, nearly 2 of 3 patients discharged from the CICU had CR indications, most commonly HFrEF. CR referrals are frequently not placed and reason for nonreferral is rarely documented. CICU admission may provide a defined event to prompt referral.

Project description:BACKGROUND:Dexmedetomidine (DEX) is a centrally acting alpha-2-adrenoceptor agonist that has potential in the management of alcohol withdrawal syndrome (AWS) owing to its ability to produce arousable sedation and to inhibit the adrenergic system without respiratory depression. The objective of this randomized controlled study was to evaluate whether addition of DEX to benzodiazepine (BZD) therapy is effective and safe for AWS patients in the intensive care unit (ICU). METHODS:Eligible participants were randomly assigned to intervention (Group D; n = 36) or control (Group C; n = 36). In Group D, DEX infusion was started at a dose of 0.2-1.4 ?g/kg/h and titrated to achieve the target sedation level (-2 to 0 on the Richmond Agitation Sedation Scale (RASS)) with symptom-triggered BZD (10 mg diazepam bolus) was used as needed. Patients in Group C received only symptom-triggered 10 mg boluses of diazepam. The primary efficacy outcomes were 24-h diazepam consumption and cumulative diazepam dose required over the course of the ICU stay; secondary outcomes included length of ICU stay, sedation and communication quality and haloperidol requirements. RESULTS:Median 24-h diazepam consumption during the study was significantly lower in Group D (20 vs. 40 mg, p < 0.001), as well as median cumulative diazepam dose during the ICU stay (60 vs. 90 mg, p < 0.001). The median percentage of time in the target sedation range was higher in Group D (median 90 % (90-95) vs. 64.5 % (60-72.5; p < 0.001). DEX infusion was also associated with better nurse-assessed patient communication (<0.001) and fewer patients requiring haloperidol treatment (2 vs. 10 p = 0.02). One patient in Group D and four in Group C were excluded owing to insufficient control of AWS symptoms and use of additional sedatives (p = 0.36). There were no severe adverse events in either group. Spontaneous breathing remained normal in all patients. Bradycardia was a common adverse event in Group D (10 vs. 2; p = 0.03). CONCLUSIONS:DEX significantly reduced diazepam requirements in ICU patients with AWS and decreased the number of patients who required haloperidol for severe agitation and hallucinations. DEX use was also associated with improvement in diverse aspects of sedation quality and the quality of patient communication. TRIAL REGISTRATION:ClinicalTrials.gov: NCT02496650.
