Potentially Preventable Hospitalization among Patients with CKD and High Inpatient Use.

ABSTRACT:

Background and objectives

Although patients with CKD are commonly hospitalized, little is known about those with frequent hospitalization and/or longer lengths of stay (high inpatient use). The objective of this study was to explore clinical characteristics, patterns of hospital use, and potentially preventable acute care encounters among patients with CKD with at least one hospitalization.

Design, setting, participants, & measurements

We identified all adults with nondialysis CKD (eGFR<60 ml/min per 1.73 m²) in Alberta, Canada between January 1 and December 31, 2009, excluding those with prior kidney failure. Patients with CKD were linked to administrative data to capture clinical characteristics and frequency of hospital encounters, and they were followed until death or end of study (December 31, 2012). Patients with one or more hospital encounters were categorized into three groups: persistent high inpatient use (upper 5% of inpatient use in 2 or more years), episodic high use (upper 5% in 1 year only), or nonhigh use (lower 95% in all years). Within each group, we calculated the proportion of potentially preventable hospitalizations as defined by four CKD-specific ambulatory care sensitive conditions: heart failure, hyperkalemia, volume overload, and malignant hypertension.

Results

During a median follow-up of 3 years, 57,007 patients with CKD not on dialysis had 118,671 hospitalizations, of which 1.7% of patients were persistent high users, 12.3% were episodic high users, and 86.0% were nonhigh users of hospital services. Overall, 24,804 (20.9%) CKD-related ambulatory care sensitive condition encounters were observed in the cohort. The persistent and episodic high users combined (14% of the cohort) accounted for almost one half (45.5%) of the total ambulatory care sensitive condition hospitalizations, most of which were attributed to heart failure and hyperkalemia. Risk of hospitalization for any CKD-specific ambulatory care sensitive condition was higher among older patients, higher CKD stage, lower income, registered First Nations status, and those with poor attachment to primary care.

Conclusions

Many hospitalizations among patients with CKD and high inpatient use are ambulatory care sensitive condition related, suggesting opportunities to improve outcomes and reduce cost by focusing on better community-based care for this population.

Project description:OBJECTIVES:Reducing potentially preventable hospitalization (PPH) among older adults with dementia is a goal of Healthy People 2020, yet no tools specifically identify patients with dementia at highest risk. The objective was to develop a risk prediction model to identify older adults with dementia at high imminent risk of PPH. DESIGN:A 30-day risk prediction model was developed using multivariable logistic regression. Patients from fiscal years (FY) 2009 to 2011 were split into development and validation cohorts; FY2012 was used for prediction. SETTING:Community-dwelling older adults (?65 years of age) with dementia who received care through the Veterans Health Administration. PARTICIPANTS:There were 1 793 783 participants. MEASUREMENTS:Characteristics associated with hospitalization risk were (1) age and other demographic factors; (2) outpatient, emergency department, and inpatient utilization; (3) medical and psychiatric diagnoses; and (4) prescribed medication use including changes to psychotropic medications (eg, initiation or dosage increase). Model discrimination was determined by the C statistic for each of the three cohorts. Finally, to determine whether predicted 30-day risk strata were stable over time, the observed PPH rate was calculated out to 1 year. RESULTS:In the development cohort, .6% of patients experienced PPH within 30?days. The C statistic for the development cohort was .83 (95% confidence interval [CI] = .83-.84) and .83 in the prediction cohort (95% CI = .82-.84). Patients in the top 10% of predicted 30-day PPH risk accounted for more than 50% of 30-day PPH admissions in all three cohorts. In addition, those predicted to be at elevated 30-day risk remained at higher risk throughout a year of follow-up. CONCLUSION:It is possible to identify older adults with dementia at high risk of imminent PPH, and their risk remains elevated for an entire year. Given the negative outcomes associated with acute hospitalization for those with dementia, healthcare systems and providers may be able to engage these high-risk patients proactively to avoid unnecessary hospitalization.

Project description:BackgroundPatients have demonstrated an eagerness to use portals to access their health information and connect with care providers. While outpatient portals have been extensively studied, there is a recognized need for research that examines inpatient portals.ObjectiveWe conducted this study to improve our understanding about the role of a portal in the context of inpatient care. Our study focused on a large sample of the general adult inpatient population and obtained perspectives from both patients and care team members about inpatient portal use.MethodsWe interviewed patients (n = 120) who used an inpatient portal during their hospitalization at 15 days or 6 months after discharge to learn about their portal use. We also interviewed care team members (n = 331) 4 weeks, 6 months, and 12 months after inpatient portal implementation to collect information about their ongoing perspectives about patients' use of the portal.ResultsThe perspectives of patients and care team members generally converged on their views of the inpatient portal. Three features-(1) ordering meals, (2) looking up health information, and (3) viewing the care team-were most commonly used; the secure messaging feature was less commonly used and of some concern to care team members. The inpatient portal benefited patients in four main ways: (1) promoted independence, (2) reduced anxiety, (3) informed families, and (4) increased empowerment.ConclusionInpatient portals are recognized as a tool that can enhance the delivery of patient-centered care. In addition to empowering patients by increasing their sense of control, inpatient portals can support family members and caregivers throughout the hospital stay. Given the consistency of perspectives about portal use across patients and care team members, our findings suggest that inpatient portals may facilitate shifts in organizational culture that increase the patient centeredness of care and improve patient experience in the hospital context.

Project description:BackgroundHigh-cost patients account for a disproportionate share of healthcare spending. The proportion and distribution of potentially preventable spending among subgroups of high-cost patients are largely unknown.ObjectiveTo examine the distribution of potentially preventable spending among high-cost Medicare patients overall and potentially preventable spending associated with each high-cost category.DesignA cross-sectional study. We merged Medicare claims and social determinants of health data to group patients into high-cost categories and quantify potentially preventable spending.PatientsA total of 556,053 Medicare fee-for-service and dual-eligible beneficiaries with at least one healthcare encounter in the New York metropolitan area in 2014.Main measuresHigh-cost patients were mapped into 10 non-mutually exclusive categories. The primary outcome was episodic spending associated with preventable ED visits, preventable hospitalizations, and unplanned 30-day readmissions.Key resultsOverall, potentially preventable spending accounted for 10.4% of overall spending in 2014. Preventable spending accounted for 13.3% of total spending among high-cost patients and 4.9% among non-high-cost patients (P < 0.001). Among high-cost patients, 44.0% experienced at least one potentially preventable encounter compared with 11.4% of non-high-cost patients (P < 0.001), and high-cost patients accounted for 71.5% of total preventable spending. High-cost patients had on average $11,502 in potentially preventable spending-more than 20 times more than non-high-cost patients ($510). High-cost patients in the seriously ill, frail, or serious mental illness categories accounted for the highest proportion of potentially preventable spending overall, while end-stage renal disease, serious illness, and opioid use disorder were associated with the highest preventable spending per patient.ConclusionPotentially preventable spending was concentrated among high-cost patients who were seriously ill, frail, or had a serious mental illness. Interventions targeting these subgroups may be helpful for reducing preventable utilization.

Project description:BACKGROUND: The intent of adopting managed care plans is to improve access to health care services while containing costs. To date, there have been a number of studies that examine the relationship between managed care and access to health care. However, the results from previous studies have been inconsistent. Specifically, previous studies did not demonstrate a clear benefit of Medicaid managed care. In this study we have examine whether Medicaid managed care is associated with the probabilities of preventable hospitalizations. This study also analyzes the spillover effect of Medicaid managed care into Medicaid patients in traditional FFS plans and the interaction effects of other patient- and county-level variables on preventable hospitalizations. METHODS: The study included 254,321 Medicaid patients who were admitted to short-term general hospital in the 67 counties in Florida. Using 2008 hospital inpatient discharge data for working-age adult Medicaid enrollees (18-64 years) in Florida, we conduct multivariate logistic regression analyses to identify possible factors associated with preventable hospitalizations. The first model includes patient- and county-level variables. Then, we add interaction terms between Medicaid HMO and other variables such as race, rurality, market-level factors, and resource for primary care. RESULTS: The results show that Medicaid HMO patients are more likely to be hospitalized for ambulatory care sensitive conditions (ACSCs) (OR?=?1.30; CI?=?1.21, 1.40). We also find that market structure (i.e., competition) is significantly associated with preventable hospitalizations. However, our study does not support that there are spillover effects of Medicaid managed care on preventable hospitalizations for other Medicaid recipients. We find that interactions between Medicaid managed care and race, rurality and market structure are significant. CONCLUSIONS: The results of our study show that the Medicaid managed care program in Florida was associated with an increase in potentially preventable hospitalizations for Medicaid enrollees. The results suggest that lower capitation rate has been associated with a greater likelihood of preventable hospitalizations for Medicaid managed care patients. Our findings also indicate that increased competition in the Medicaid managed care market has no clear benefit in Medicaid managed care patients.

Project description:Backgroundand objectives Patients with CKD are at risk of hospital-acquired complications (HACs). We sought to determine the association of preventable HACs with mortality, length of stay (LOS), and readmission.Design, setting, participants, & measurementsAll adults hospitalized from April of 2003 to March of 2008 in Alberta were characterized by kidney function and occurrence of preventable HACs. CKD was defined by eGFR<60 ml/min per 1.73 m2 and/or albumin-to-creatinine ratio >3-30 mg/mmol for >3 months in the time frame from 365 to 90 days before admission. Regression models examined the association of HACs with outcomes.ResultsOf 536,549 hospitalizations, 8.5% (n=45,733) had CKD and 9.8% of patients with CKD had one or more potentially preventable HAC. In patients with potentially preventable HACs, proportions of death within index hospitalization and from discharge to 90 days were 17.7% and 6.8%, respectively. In patients with CKD, comparing with those hospitalizations without potentially preventable HACs, the adjusted odds ratio (OR) of mortality during index hospitalization and from hospital discharge to 90 days in patients with one or more preventable HAC was 4.67 (95% confidence interval [95% CI], 4.17 to 5.22) and 1.08 (95% CI, 0.94 to 1.25), respectively. Median incremental LOS in patients with one or more preventable HAC was 9.86 days (95% CI, 9.25 to 10.48). The OR for readmission with preventable HAC was 1.24 (95% CI, 1.15 to 1.34). In a cohort with and without CKD, the adjusted ORs of mortality during index hospitalization in patients with CKD and no preventable HACs, patients without CKD and with preventable HACs, and patients with CKD and preventable HACs were 2.22 (95% CI, 1.69 to 2.94), 5.26 (95% CI, 4.98 to 5.55), and 9.56 (95% CI, 7.23 to 12.56), respectively (referenced to patients without CKD or preventable HACs).ConclusionsPreventable HACs are associated with higher mortality, incremental LOS, and greater risk of readmission, especially in people with CKD. Targeted strategies to reduce complications should be a high priority.
