Association of Positive Delirium Screening with Incident Dementia in Skilled Nursing Facilities.
Ontology highlight
ABSTRACT: Background and objective
Early detection of delirium in skilled nursing facilities (SNFs) is a priority. The extent to which delirium screening leads to a potentially inappropriate diagnosis of Alzheimer's disease and related dementia (ADRD) is unknown.Design
Nationwide retrospective cohort study from 2011 to 2013.Setting
An SNF.Participants
A total of 1,175,550 Medicare enrollees who entered the SNF from a hospital and had no prior diagnosis of dementia.Exposure
A positive screen for delirium using the validated Confusion Assessment Method (CAM), performed as part of the federally mandated Minimum Data Set (MDS) assessment.Measurements
Incident all-cause dementia, ascertained through International Classification of Diseases, Ninth Revision (ICD-9), diagnosis in Medicare claims or active diagnoses in MDS.Results
Positive screening for delirium was identified in 7.7% of cases (n = 90,449), and most occurred within the first 7 days of SNF admission (62.5%). The overall incidence of ADRD was 6.3% (n = 73,542). Nearly all new diagnoses of ADRD (93.5%) occurred within the first 30 days of SNF admission. Patients who screened CAM positive for delirium had a nearly threefold increased risk of receiving an incident ADRD diagnosis on the same day (hazard ratio (HR) = 2.63; 95% confidence interval (CI) = 1.50-4.63). Among patients who screened CAM positive for delirium, those who were cognitively intact or had mild cognitive impairments were, on average, six times more likely to receive an incident ADRD diagnosis (HR = 6.64; 95% CI = 1.76-25.0) relative to those testing CAM negative.Conclusion and relevance
Among older adults not previously diagnosed with dementia, a positive screen for delirium was significantly associated with higher risk of ADRD diagnosis after admission to a SNF. This risk was highest for patients in the first days of their stay and with the least cognitive impairment, suggesting that the ADRD diagnosis was potentially inappropriate.

Project description:BackgroundThe extent to which a positive delirium screening and new diagnosis of Alzheimer's disease or related dementias (ADRD) increases the risk for re-hospitalization, long-term nursing home placement, and death remains unknown.ObjectiveTo compare long-term outcomes among newly admitted skilled nursing facility (SNF) patients with delirium, incident ADRD, and both conditions.Design, setting, and participantsA retrospective cohort study of Medicare beneficiaries who entered a SNF from hospital with a minimum 14-day stay (n = 100,832) from 2015 to 2016.Main measuresReturn to home, hospital readmission, admission to a long-term care facility, or death.Key resultsPatients with delirium were as likely to be discharged home as patients diagnosed with ADRD (HR: 0.63, 95% CI: 0.59, 0.67; HR: 0.65, 95% CI: 0.64, 0.67). Patients with both delirium and ADRD were less likely to be discharged home (HR: 0.49, 95% CI: 0.47, 0.52) and showed increased risk of death (HR: 1.30, 95% CI: 1.17, 1.45). Patients with ADRD, regardless of delirium screening status, had increased risk for long-term nursing home care transfer (HR: 1.66, 95% CI: 1.63, 1.70; HR: 1.76, 95% CI: 1.69, 1.82). Patients with delirium and no ADRD showed increased risk of transfer to long-term nursing home care (HR: 1.25, 95% CI: 1.18, 1.33). The rate of deaths was higher among patients who screened positive for delirium without ADRD compared to the no delirium and no ADRD groups (HR: 2.35, 95% CI: 2.11, 2.61).ConclusionA positive delirium screening increased risk of death and transfer to long-term care in the first 100 days after admission regardless of incident ADRD diagnosis. Patients with delirium and/or ADRD also are less likely to be discharged home. Our study builds on the evidence base that delirium is important to address in older adults as it is associated with negative outcomes.

Project description:ObjectivesTo determine whether a delirium abatement program (DAP) can shorten duration of delirium in new admissions to postacute care (PAC).DesignCluster randomized controlled trial.SettingEight skilled nursing facilities specializing in PAC within a single metropolitan region.ParticipantsFour hundred fifty-seven participants with delirium at PAC admission.InterventionThe DAP consisted of four steps: assessment for delirium within 5 days of PAC admission, assessment and correction of common reversible causes of delirium, prevention of complications of delirium, and restoration of function.MeasurementsTrained researchers screened eligible patients. Those with delirium defined according to the Confusion Assessment Method were eligible for participation using proxy consent. Regardless of location, researchers blind to intervention status re-assessed participants for delirium 2 weeks and 1 month after enrollment.ResultsNurses at DAP sites detected delirium in 41% of participants, versus 12% in usual care sites (P<.001), and completed DAP documentation in most participants in whom delirium was detected, but the DAP intervention had no effect on delirium persistence based on two measurements at 2 weeks (DAP 68% vs usual care 66%) and 1 month (DAP 60% vs usual care 51%) (adjusted P> or =.20). Adjusting for baseline differences between DAP and usual care participants and restricting analysis to DAP participants in whom delirium was detected did not alter the results.ConclusionDetection of delirium improved at the DAP sites, but the DAP had no effect on the persistence of delirium. This effectiveness trial demonstrated that a nurse-led DAP intervention was not effective in typical PAC facilities.

Project description:AimHeart failure (HF) outcomes are disproportionately worse in patients discharged to skilled nursing facilities (SNF) as opposed to home. We hypothesized that dementia and delirium were key factors influencing these differences. Our aim was to explore the associations of dementia and delirium with risk of hospital readmission and mortality in HF patients discharged to SNF.Methods and resultsThe study population included Veterans hospitalized for a primary diagnosis of HF and discharged to SNFs between 2010 and 2015. Pre-existing dementia was identified based on International Classification of Diseases-9 codes. Delirium was determined using the Minimum Data Set 3.0 Confusion Assessment Method algorithm. Proportional hazard regression analyses were used to model outcomes and were adjusted for covariates of interest. Patients (n = 21 655) were older (77.0 ± 10.5 years) and predominantly male (96.9%). Four groups were created according to presence (+) or absence (-) of dementia and delirium. Relative to the dementia-/delirium- group, the dementia-/delirium+ group was associated with increased 30 day mortality [adjusted hazard ratio (HR) = 2.2, 95% confidence interval (CI) = 1.7, 3.0] and 365 day mortality (adjusted HR = 1.5, 95% CI = 1.3, 1.7). Readmission was highest in the dementia-/delirium+ group after 30 days (HR = 1.2, 95% CI = 1.0, 1.5). In the group with dementia (delirium-/dementia+), 30 day mortality (12.8%; HR = 0.7, 95% CI = 0.7, 0.8) and readmissions (5.3%; HR = 1.0, 95% CI = 0.8, 1.1) were not different relative to the reference group.ConclusionsDelirium, independent of pre-existing dementia, confers increased risk of hospital readmission and mortality in HF patients discharged to SNFs. Managing HF after hospitalization is a complex cognitive task and an increased focus on mental status in the acute care setting prior to discharge is needed to improve HF management and transitional care, mitigate adverse outcomes, and reduce healthcare costs.

Project description:ImportanceA substantial number of patients discharged to skilled nursing facilities (SNFs) after heart failure (HF) hospitalization experience regression in function or do not improve. Delirium is one of few modifiable risk factors in this patient population. Therefore, understanding the role of delirium in functional recovery may be useful for improving outcomes.ObjectiveTo assess the association of delirium with 30-day functional improvement in patients discharged to SNFs after HF hospitalization.Design, setting, and participantsThis retrospective cohort study included patients hospitalized for HF in 129 US Department of Veterans Affairs hospitals who were discharged to SNFs from October 1, 2010, to September 30, 2015. Data were analyzed from June 14 to December 18, 2020.ExposuresDelirium, as determined by the Minimum Data Set (MDS) 3.0 Confusion Assessment Method, with dementia as a covariate, determined via International Classification of Diseases, Ninth Revision (ICD-9) coding.Main outcomes and measuresThe difference between admission and 30-day MDS 3.0 Activities of Daily Living (ADL) scores.ResultsA total of 20 495 patients (mean [SD] age, 78 [10.3] years; 78.9% White; and 97% male) were included in the analysis. Of the total sample, 882 patients (4.3%) had delirium on an SNF admission. The mean (SD) baseline ADL score on admission to SNF was significantly worse among patients with delirium than without (18.3 [4.7] vs 16.1 [5.2]; P < .001; d = 0.44.). On the 30-day repeated assessment, mean (SD) function (ADL scores) improved for both patients with delirium (0.6 [2.9]) and without delirium (1.8 [3.6]) (P < .001; d = -0.38). In the multivariate adjusted model, delirium was associated with statistically significant lower ADL improvement (difference in ADL score, -1.07; 95% CI, -1.31 to -0.83; P < .001).Conclusions and relevanceIn this retrospective cohort study, patients with HF discharged to SNFs with delirium were less likely to show improvement in function compared with patients without delirium. Findings suggest a potential need to reexamine how and when health care professionals assess delirium in HF patients throughout their hospitalization and SNF course. Identifying and treating delirium for HF patients earlier in their care trajectory may play an important role in improving care and long-term functional outcomes in this population. Future research is warranted to further investigate the association between delirium and functional recovery for HF and other patient populations.

Project description:ObjectivesTo examine the association of patient and direct-care staff beliefs about patients' capability to increase independence with activities of daily living (ADL) and the probability of successful discharge to the community after a skilled nursing facility (SNF) stay.DesignRetrospective cohort study of SNF patients using 100% Medicare inpatient claims and Minimum Data Set resident assessment data. Linear probability models were used to estimate the probability of successful discharge based on patient and staff beliefs about the patient's ability to improve in function, as well as patient and staff beliefs together. Estimates were adjusted for demographics, health status, functional characteristics, and SNF fixed effects.ParticipantsFee-for-service Medicare beneficiaries (N=526,432) aged 66 years or older who were discharged to an SNF after hospitalization for stroke, hip fracture, or traumatic brain injury.InterventionsNot applicable.Main outcome measuresSuccessful community discharge (discharged alive within 90d of SNF admission and remaining in the community for ≥30d without dying or health care facility readmission).ResultsPatients with positive beliefs about their capability to increase independence with ADLs had a higher adjusted probability of successful discharge than patients with negative beliefs (positive, 63.8%; negative, 57.8%; difference, 6.0%, 95% confidence interval [CI], 5.4-6.6). This remained true regardless of staff beliefs, but the difference in successful discharge probability between patients with positive and negative beliefs was larger when staff had positive beliefs. Conversely, the association between staff beliefs and successful discharge varied based on patient beliefs. If patients had positive beliefs, the difference in the probability of successful discharge between positive and negative staff beliefs was 2.5% (95% CI, 1.0-4.0). If patients had negative beliefs, the difference between positive and negative staff beliefs was -4.6% (95% CI, -6.0 to -3.2).ConclusionsPatients' beliefs have a significant association with the probability of successful discharge. Understanding patients' beliefs is critical to appropriate goal-setting, discharge planning, and quality SNF care.

Project description:ImportanceTelemedicine in skilled nursing facilities (SNFs) has the potential to improve access and timeliness of care. During the COVID-19 pandemic in 2020 to 2022, telemedicine coverage expanded, but little is known about patterns of use in SNFs.ObjectiveTo describe patterns of telemedicine use in SNFs.Design, setting, and participantsThis cohort study used 2018 to 2022 Medicare fee-for-service claims and Minimum Data Set 3.0 records to identify short- and long-term care SNF residents. Clinician visits were grouped into routine SNF visits (ie, regular primary care within SNF) and other outpatient visits (ie, with non-SNF affiliated primary and specialty care clinicians). Using a difference-in-differences approach, assessments included whether off-hours visits (measured as weekend visits), new specialist visits, psychiatrist visits, or visits for residents with limited mobility changed differentially between 2018 to 2019 and 2020 to 2021 for SNFs with high compared with low telemedicine use in 2020.ExposureTelemedicine adoption at SNF after 2020.Main outcomes and measuresNumber and proportion of telemedicine SNF and outpatient visits.ResultsAcross 15 434 SNFs and 4 463 591 residents from the period January 2019 through June 2022 (mean [SD] age, 79.7 [11.6] years; 61% female in 2020), telemedicine visits increased from 0.15% in January 2019 to February 2020 to 15% SNF visits and 25% outpatient visits in May 2020. By 2022, telemedicine dropped to 2% of SNF visits and 8% of outpatient visits. The proportion of SNFs with any telemedicine visits annually dropped from 91% in 2020 to 61% in 2022. The facilities with high telemedicine use were more likely to be rural (adjusted odds ratio vs urban, 2.06; 95% CI, 1.77 to 2.40). Psychiatry visits differentially increased in high vs low telemedicine-use SNFs (20.2% relative increase; 95% CI, 1.2% to 39.2%). In contrast, there was little change in outpatient visits for residents with limited mobility (7.2%; 95% CI, -0.1% to 14.6%) or new specialist visits (-0.7%; 95% CI, -2.5% to 1.2%).Conclusions and relevanceIn this cohort study of SNF residents, telemedicine was rapidly adopted in early 2020 but subsequently stabilized at a low use rate that was nonetheless higher than before 2020. Higher telemedicine use in SNFs was associated with improved access to psychiatry visits in SNFs. A policy to encourage continued telemedicine use may facilitate further access to important services as the technology matures.

Project description:Importance:There are areas of skilled nursing facility (SNF) experience of importance to the public that are not currently included in public reporting initiatives on SNF quality. Whether patients, hospitals, and payers can leverage the information available from unsolicited online reviews to reduce avoidable rehospitalizations from SNFs is unknown. Objectives:To assess the association between rehospitalization rates and online ratings of SNFs; to compare the association of rehospitalization with ratings from a review website vs Medicare Nursing Home Compare (NHC) ratings; and to identify specific topics consistently reported in reviews of SNFs with the highest vs lowest rehospitalization rates using natural language processing. Design, Setting, and Participants:A retrospective cross-sectional study of 1536 SNFs with online reviews on Yelp (a website that allows consumers to rate and review businesses and services, scored on a 1- to 5-star rating scale, with 1 star indicating the lowest rating and 5 stars indicating the highest rating) posted between January 1, 2014, and December 31, 2018. The combined data set included 1536 SNFs with 8548 online reviews, NHC ratings, and readmission rates. Main Outcomes and Measures:A mean rating from the review website was calculated through the end of each year. Risk-standardized rehospitalization rates were obtained from NHC. Linear regression was used to measure the association between the rehospitalization rate of a SNF and the online ratings. Natural language processing was used to identify topics associated with reviews of SNFs in the top and bottom quintiles of rehospitalization rates. Results:The 1536 SNFs in the sample had a median of 6 reviews (interquartile range, 3-13 reviews), with a mean (SD) review website rating of 2.7 (1.1). The SNFs with the highest rating on both the review website and NHC had 2.0% lower rehospitalization rates compared with the SNFs with the lowest rating on both websites (21.3%; 95% CI, 20.7%-21.8%; vs 23.3%; 95% CI, 22.7%-24.0%; P?=?.04). Compared with the NHC ratings alone, review website ratings were associated with an additional 0.4% of the variation in rehospitalization rates across SNFs (adjusted R2?=?0.009 vs adjusted R2?=?0.013; P?=?.003). Thematic analysis of qualitative comments on the review website for SNFs with high vs low rehospitalization rates identified several areas of importance to the reviewers, such as the quality of physical infrastructure and equipment, staff attitudes and communication with caregivers. Conclusions and Relevance:Skilled nursing facilities with the best rating on both a review website and NHC had slightly lower rehospitalization rates than SNFs with the best rating on NHC alone. However, there was marked variation in the volume of reviews, and many SNF characteristics were underrepresented. Further refinement of the review process is warranted.

Project description:Background and purposePhysical and occupational therapy practices in skilled nursing facilities (SNFs) were greatly impacted by the 2019 Medicare Patient-Driven Payment Model (PDPM). Under the PDPM, the practice of multiparticipant therapy-treating more than one patient per therapy provider per session-increased in SNFs, but it is unknown how substituting multiparticipant therapy for individualized therapy may impact patient outcomes. This cross-sectional study establishes baseline relationships between multiparticipant therapy and patient outcomes using pre-PDPM data.MethodsWe used Minimum Data Set assessments from all short-term Medicare fee-for-service SNF stays in 2018. Using generalized mixed-effects logistic regression adjusted for therapy volume and patient factors, we examined associations between the proportion of minutes of physical and occupational therapy that were received as multiparticipant sessions during the SNF stay and 2 outcomes: community discharge and functional improvement. Multiparticipant therapy minutes as a proportion of total therapy time were categorized as none, low (below the median of 5%), medium (median to <25%), and high (≥25%) to reflect the 25% multiparticipant therapy limit required by the PDPM.Results and discussionWe included 901 544 patients with complete data for functional improvement and 912 996 for the discharge outcome. Compared with patients receiving no multiparticipant therapy, adjusted models found small positive associations between low and medium multiparticipant therapy levels and outcomes. Patients receiving low levels of multiparticipant therapy had 14% higher odds of improving in function (95% CI 1.09-1.19) and 10% higher odds of community discharge (95% CI 1.05-1.15). Patients receiving medium levels of multiparticipant therapy had 18% higher odds of functional improvement (95% CI 1.13-1.24) and 44% higher odds of community discharge (95% CI 1.34-1.55). However, associations disappeared with high levels of multiparticipant therapy.ConclusionsPrior to the PDPM, providing up to 25% multiparticipant therapy was an efficient strategy for SNFs that may have also benefitted patients. As positive associations disappeared with high levels (≥25%) of multiparticipant therapy, it may be best to continue delivering the majority of therapy in SNFs as individualized treatment.

Project description:OBJECTIVES:To determine the association between therapy intensity and discharge outcomes for aged Medicare skilled nursing facilities (SNFs) fee-for-service beneficiaries and to determine the association between therapy intensity and time to community discharge. DESIGN:Retrospective observational design. SETTING:SNFs. PARTICIPANTS:Aged Medicare fee-for-service beneficiaries (N=311,338) in 3605 SNFs. INTERVENTIONS:The total minutes of physical therapy, occupational therapy, and speech therapy per day were divided into intensity groups: high (?60min); medium-high (45-<60min); medium-low (30-<45min); and low (<30min). MAIN OUTCOME MEASURES:Four discharge outcomes-community, hospitalization, permanent placement, and death-were examined using a multivariate competing hazards model. For those associated with community discharge, a Poisson multivariate model was used to determine whether length of stay differed by intensity. RESULTS:High intensity therapy was associated with more community discharges in comparison to the remaining intensity groups (hazard ratio, .84, .68, and .433 for medium-high, medium-low, and low intensity groups, respectively). More hospitalizations and deaths were found as therapy intensity decreased. Only high intensity therapy was associated with a 2-day shorter length of stay (incident rate ratio, .95). CONCLUSIONS:High intensity therapy was associated with desirable discharge outcomes and may shorten SNF length of stay. Despite growing reimbursements to SNFs for rehabilitation services, there may be desirable benefits to beneficiaries who receive high intensity therapy.

Project description:ObjectiveTo understand how hospital-based clinicians evaluate older adults in the hospital and decide who will be transferred to a skilled nursing facility (SNF) for postacute care.DesignSemistructured interviews paired with a qualitative analytical approach informed by Social Constructivist theory.SettingInpatient care units in three hospitals. Purposive sampling was used to maximize variability in hospitals, units within hospitals, and staff on those units.ParticipantsClinicians (hospitalists, nurses, therapists, social workers, case managers) involved in evaluation and decision-making regarding postacute care (N = 25).MeasurementsCentral themes related to clinician evaluation and discharge decision-making.ResultsClinicians described pressure to expedite evaluation and discharge decisions, resulting in the use of SNFs as a "safety net" for older adults being discharged from the hospital. The lack of hospital-based clinician knowledge of SNF care practices, quality, or patient outcomes resulted in lack of a standardized evaluation process or a clear primary decision-maker.ConclusionHospital clinician evaluation and decision-making about postacute care in SNFs may be characterized as rushed, without a clear system or framework for making decisions and uninformed by knowledge of SNF or patient outcomes in those discharged to SNFs. This leads to SNFs being used as a "safety net" for many older adults. As hospitals and SNFs are increasingly held jointly accountable for outcomes of individuals transitioning between hospitals and SNFs, novel solutions for improving evaluation and decision-making are urgently needed.
