Background
The Minimum Data Set (MDS) 3.0 introduced the Brief Interview for Mental Status (BIMS), a short performance-based cognitive screener for nursing home (NH) residents. Not all residents are able to complete the BIMS and are consequently assessed by staff. We designed a Cognitive Function Scale (CFS) integrating self-report and staff-report data and present evidence of the scale’s construct validity.
Design
Retrospective cohort study.
Subjects
Consisted of three cohorts: 1) long-stay NH residents (N=941,077) and 2) new admissions (N=2,066,580) during 2011–2012, and 3) residents with the older MDS 2.0 assessment in 2010 and the newer MDS 3.0 assessment (n=688,511).
Measures
MDS 3.0 items were used to create a single, integrated four-category hierarchical CFS that was compared to residents’ prior MDS 2.0 Cognitive Performance Scale scores and other concurrent MDS 3.0 measures of construct validity.
Results
The new CFS suggests that 28% of the long-stay cohort in 2011–2012 were cognitively intact, 22% were mildly impaired, 33% were moderately impaired, and 17% were severely impaired. For the admission cohort, the CFS noted 56% as cognitively intact, 23% as mildly impaired, 17% as moderately impaired, and 4% as severely impaired. The CFS corresponded closely with residents’ prior MDS 2.0 Cognitive Performance Scale scores and with performance of Activities of Daily Living, and nurses’ judgments of function and behavior in both the admission and long-stay cohorts.
Conclusion
The new CFS is valuable to researchers as it provides a single, integrated measure of NH residents’ cognitive function, regardless of the mode of assessment.
Context
Tube-feeding is of questionable benefit for nursing home residents with advanced dementia. Approximately two-thirds of US nursing home residents who are tube fed had their feeding tube inserted during an acute care hospitalization.
Objective
To identify US hospital characteristics associated with higher rates of feeding tube insertion in nursing home residents with advanced cognitive impairment.
Design, Setting, and Patients
The sample included nursing home residents aged 66 years or older with advanced cognitive impairment admitted to acute care hospitals between 2000 and 2007. Rate of feeding tube placement was based on a 20% sample of all Medicare Claims files and was assessed in hospitals with at least 30 such admissions during the 8-year period. A multivariable model with the unit of the analysis being the hospital admission identified hospital-level factors independently associated with feeding tube insertion rates, including bed size, ownership, urban location, and medical school affiliation. Measures of each hospital’s care practices for all patients with serious chronic illnesses were evaluated, including intensive care unit (ICU) use in the last 6 months of life, the use of hospice services, and the ratio of specialist to primary care physicians. Patient-level characteristics were also considered.
Main Outcome Measure
Endoscopic or surgical insertion of a gastrostomy tube during a hospitalization.
Results
In 2797 acute care hospitals with 280 869 admissions among 163 022 nursing home residents with advanced cognitive impairment, the rate of feeding tube insertion varied from 0 to 38.9 per 100 hospitalizations (mean [SD], 6.5 [5.3]; median [interquartile range], 5.3 [2.6–9.3]). The mean rate of feeding tube insertions per 100 admissions was 7.9 in 2000, decreasing to 6.2 in 2007. Higher insertion rates were associated with the following hospital features: for-profit ownership vs government owned (8.5 vs 5.5 insertions per 100 hospitalizations; adjusted odds ratio [AOR], 1.33; 95% confidence interval [CI], 1.21–1.46), larger size (>310 beds vs <101 beds: 8.0 vs 4.3 insertions per 100 hospitalizations; AOR, 1.48; 95% CI, 1.35–1.63), and greater ICU use in the last 6 months of life (highest vs lowest decile: 10.1 vs 2.9 insertions per 100 hospitalizations; AOR, 2.60; 95% CI, 2.20–3.06). These differences persisted after controlling for patient characteristics. Specialist to primary care ratio and hospice use were weakly or not associated with feeding tube placement.
Conclusion
Among nursing home residents with advanced cognitive impairment admitted to acute care hospitals, for-profit ownership, larger hospital size, and greater ICU use was associated with increased rates of feeding tube insertion, even after adjusting for patient-level characteristics.
The combination of vancomycin plus piperacillin-tazobactam increased the odds of acute kidney injury over vancomycin monotherapy, vancomycin plus cefepime or carbapenem, and piperacillin-tazobactam monotherapy. Limited data in critically ill patients suggest the odds of acute kidney injury are increased versus vancomycin monotherapy, and mitigated versus the other comparators. Further research in the critically ill population is needed.
Objective
To examine the differential morbidity/mortality associated with evacuation versus sheltering in place for nursing home (NH) residents exposed to the 4 most recent Gulf-hurricanes
Methods
Observational study using Medicare claims, and NH data sources. We compared the differential mortality/morbidity for long-stay residents exposed to 4 recent hurricanes (Katrina, Rita, Gustav, and Ike) relative to those residing at the same NHs over the same time periods during the prior 2 non-hurricane years as a control. Using an instrumental variable analysis, we then evaluated the independent effect of evacuation on outcomes at 90 days.
Results
Among 36,389 NH residents exposed to a storm, the 30 and 90 day mortality/hospitalization rates increased compared to non-hurricane control years. There were a cumulative total of 277 extra deaths and 872 extra hospitalizations at 30 days. At 90 days, 579 extra deaths and 544 extra hospitalizations were observed. Using the instrumental variable analysis, evacuation increased the probability of death at 90 days from 2.7-5.3% and hospitalization by 1.8-8.3%, independent of other factors.
Conclusion
Among residents exposed to hurricanes, evacuation significantly exacerbated subsequent morbidity/mortality.
