End-stage renal disease and outcome in a surgical intensive care unit.

ABSTRACT:

Introduction

End-stage renal disease (ESRD) is associated with an increased propensity for critical illness, but whether ESRD is independently associated with a greater risk of death after major surgical procedures is unclear.

Methods

This was a retrospective analysis of prospectively collected data from all adult (>18 years) patients admitted to a 50-bed surgical intensive care unit (ICU) between January 2004 and January 2009. ESRD was defined as the need for chronic peritoneal dialysis or hemodialysis for at least 6 weeks prior to ICU admission. We used multivariable logistic regression analysis and propensity-score matching to adjust for possible confounders.

Results

In total, 12,938 adult patients were admitted during the study period; 199 patients had ESRD at ICU admission, giving a prevalence of 1.5%. Patients with ESRD were more likely to be male (72.9% versus 63.0%, P?=?0.004) and had higher severity scores, a higher incidence of diabetes mellitus and cirrhosis, and a lower incidence of cancer at ICU admission than those without ESRD. Patients with ESRD were more likely to have any type of organ failure at ICU admission and during the ICU stay. Patients with ESRD had higher ICU and hospital mortality rates (23.1% and 31.2% versus 5.5% and 10.0%, respectively, P <0.001 pairwise) and longer ICU length of stay (2 (1 to 7) versus 1 (1 to 3) days, P <0.001). In multivariable logistic regression analysis, ESRD was independently associated with a greater risk of in-hospital death (odds ratio?=?3.84, 95% confidence interval 2.68 to 5.5, P <0.001). In 199 pairs of patients, hematologic and hepatic failures were more prevalent, ICU and hospital mortality rates were higher (23.1% versus 15.1% and 31.2% versus 19.1%, P <0.05 pairwise), and ICU length of stay was longer (2 (1 to 7) versus 1 (1 to 7) days, P <0.001) in patients with ESRD.

Conclusions

In this large cohort of surgical ICU patients, presence of ESRD at ICU admission was associated with greater morbidity and mortality and independently associated with a greater risk of in-hospital death. Our data can be useful in preoperative risk stratification.

Project description:ImportanceMedicare beneficiaries with end-stage renal disease (ESRD) are a medically complex group accounting for less than 1% of the Medicare population but more than 7% of Medicare fee-for-service payments.ObjectiveTo evaluate the association of the Comprehensive End-Stage Renal Disease Care (CEC) model with Medicare payments, health care use, and quality of care.Design, setting, and participantsIn this economic evaluation, a difference-in-differences design estimated the change in outcomes for 73 094 Medicare fee-for-service beneficiaries aligned to CEC dialysis facilities between the baseline (from January 2014 to March 2015) and intervention periods (from October 2015 to December 2017) relative to 60 464 beneficiaries at matched dialysis facilities. In the CEC model, dialysis facilities, nephrologists, and other providers partner to form ESRD Seamless Care Organizations (ESCOs), specialty-oriented accountable care organizations that coordinate care for beneficiaries with ESRD. ESCOs with expenditures below a benchmark set by the Centers for Medicare & Medicaid Services are eligible to share in savings if they meet quality thresholds. A total of 685 dialysis facilities affiliated with 37 ESCOs participated in the CEC model as of January 2017. Thirteen ESCOs joined the CEC model on October 1, 2015 (wave 1), and 24 ESCOs joined on January 1, 2017 (wave 2). Patients with ESRD who were aligned with CEC dialysis facilities were compared with patients at matched dialysis facilities.Main outcomes and measuresMedicare total and service-specific payments per beneficiary per month; hospitalizations, readmissions, and emergency department visits; and select quality measures.ResultsRelative to the comparison group (n = 60 464; 55% men; mean [SD] age, 63.5 [14.4] years), total Medicare payments for CEC beneficiaries (n = 73 094; 56% men; mean [SD] age, 63.0 [14.4] years) decreased by $114 in payments per beneficiary per month (95% CI, -$202 to -$26; P = .01), associated primarily with decreases in payments for hospitalizations and readmissions. Payment reductions were offset by shared savings payments to ESCOs, resulting in net losses of $78 in payments per beneficiary per month (95% CI, -$8 to $164; P = .07). Relative to the comparison group, CEC beneficiaries had 5.01 fewer hospitalizations per 1000 beneficiaries per month (95% CI, -8.45 to -1.56; P = .004), as well as fewer catheter placements (CEC beneficiaries with catheter as vascular access for periods longer than 90 days decreased by 0.78 percentage points [95% CI, -1.36 to -0.19; P = .01]) and fewer hospitalizations for ESRD complications (CEC beneficiaries were 0.11 percentage points less likely [95% CI, -0.20 to -0.02; P = .01] to be hospitalized in a given month). Total dialysis sessions and payments increased, suggesting improved adherence to dialysis treatments.Conclusions and relevanceEarly findings from the CEC model demonstrate that a specialty accountable care organization model focused on a particular population was associated with reduced payments and improved quality of care. Future research can assess the longer-term outcomes of the CEC model and its applicability to populations with other complex chronic conditions.

Project description:BackgroundPrevious studies have demonstrated that early pre-end-stage renal disease (ESRD) nephrology care could improve postdialysis prognosis. However, less is known about the specific types of interventions responsible for the improved outcomes. We hypothesized that more frequent predialysis laboratory testing is associated with better postdialysis outcomes in incident ESRD patients.MethodsIn all, 23?089 patients with available outpatient laboratory tests performed during the 2-year predialysis (i.e. prelude) period were identified from a total of 52?172 American veterans with chronic kidney disease (CKD) transitioning to dialysis between October 2007 and September 2011. The associations between the frequency of combined laboratory tests, including serum creatinine, serum potassium and hemoglobin (test trio), with postdialysis mortality and hospitalization were examined in multivariable adjusted Cox and logistic regression models.ResultsWhen entering the 2-year prelude period, the mean age (Standard Deviation) of the patients was 66.2 (SD 11.3)?years and the mean estimated glomerular filtration rate was 46.8 (SD 23.9)?mL/min/1.73 m2. In all, 14% of patients had the test trio performed less than twice in 24?months and 8.9% had the trio measured more often than every other month. Over a 2.5-year median postdialysis follow-up period, 15?303 (66.3%) patients died (mortality rate 260/1000 patient-years). The adjusted hazard ratio of all-cause mortality and adjusted odds ratio of the composite of hospitalization or death associated with lab testing done >12/24?months compared with 2-?4/24 months were 0.68 [95% confidence interval (CI) 0.65-0.73] and 0.70 (95% CI 0.62-0.79), respectively.ConclusionsMore frequent laboratory testing in patients with advanced CKD is associated with better clinical outcomes after dialysis. Further examination in clinical trials is needed before the implementation of more frequent laboratory testing in clinical practice.

Project description:ImportanceHigh health care costs encourage initiatives that avoid overuse of resources and identify opportunities to promote appropriate care.ObjectiveTo investigate the causes of potentially avoidable surgical intensive care unit (SICU) admissions and disposition delays to determine whether targeted interventions could decrease these stays.Design, setting, and participantsThis prospective, observational study focused on potentially avoidable SICU days, as determined by observers with input from the rounding intensivists at a 24-bed open SICU at an urban, academic hospital. The preintervention phase occurred from April 6 through June 21, 2015; after implementation of targeted interventions, the postintervention phase occurred from April 4 through June 28, 2016. Data collected included demographic characteristics, reason for admission, and length of stay. All patients admitted to the SICU during the preintervention and postintervention phases were included in the analysis.InterventionsBased on results collected in the preintervention phase, targeted interventions were designed and implemented from July 1, 2015, through March 31, 2016, including (1) reducing SICU care for minor traumatic brain injury, (2) optimizing postoperative airway management, (3) enhancing communication between services regarding transfers to the SICU, (4) identifying and facilitating more timely end-of-life conversations and supportive care consultations, and (5) encouraging early disposition of patients to floor beds.Main outcomes and measuresChanges in the proportion of potentially avoidable SICU days owing to potentially avoidable admissions and/or disposition delays.ResultsA total of 459 patients (253 men [55.1%] and 206 women [44.9%]; median age, 62 years [interquartile range, 46-75 years]) were admitted during the preintervention and postintervention phases. Of 261 patients admitted during the preintervention period and 245 during the postintervention period, median SICU and hospital length of stay remained unchanged. A reduction was noted in the percentage of postintervention SICU days owing to potentially avoidable admissions (152 of 1168 days [13%] vs 118 of 1338 days [8.8%]; P?=?.001) and disposition delays (138 of 1168 days [11.8%] vs 97 of 1338 days [7.2%]; P?<?.001). During the postintervention period, decreases were noted in the SICU days related to the most common sources of potentially avoidable admissions (SICU stay ?24 hours, airway concerns, and somnolence) and disposition delays (end-of-life decisions and floor bed unavailable) as well as in the overall rate of potentially avoidable days (269 of 1168 days [23%] vs 205 of 1338 days [15.3%]; P?<?.001).Conclusions and relevanceNearly one-fourth of SICU days could be categorized as potentially avoidable. Targeted interventions resulted in a significant reduction of potentially avoidable SICU days.
