Achieving Functional Goals During a Skilled Nursing Facility Stay: A National Study of Medicare Beneficiaries

OBJECTIVES

The aims of the study are to describe the frequency that functional goals are documented on the Minimum Data Set and to identify resident characteristics associated with meeting or exceeding discharge goals.

METHODS

We selected Medicare fee-for-service beneficiaries admitted to a skilled nursing facility within 3 days of hospital discharge from October 1, 2018, to December 31, 2019 ( N = 1,228,913). The admission Minimum Data Set was used to describe the discharge goal scores for seven self-care and 16 mobility items. We used the eight self-care and mobility items originally included in a publicly reported quality measure to calculate total scores for discharge goals, admission performance, and discharge performance ( n = 371,801).

RESULTS

For all self-care items, more than 70% of residents had a goal score of 1-6 points documented on the admission Minimum Data Set. Chair/bed-to-chair transfer had the highest percentage of residents with a score of 1-6 points (77.1%) and walking up/down 12 steps had the lowest (23.2%). Approximately 44% of residents had a discharge performance score that met or exceeded their goal score. Older age, urinary incontinence, and cognitive impairment had the lowest odds of meeting or exceeding discharge goals.

CONCLUSIONS

Assessing a resident's functional goals is important to providing patient-centered care. This information may help skilled nursing facilities determine whether a resident has made meaningful functional improvements.

Care patterns and predictors of community residence among older patients after hospital discharge for traumatic brain injury

BACKGROUND

An increasing number of older adults with traumatic brain injury (TBI) require hospitalization, but it is unknown whether they return to their community following discharge. We examined community residence following acute hospital discharge for TBI in Texas and identified factors associated with 90-day community residence and readmission.

METHODS

We conducted a retrospective cohort study using 100% Texas Medicare claims data of patients older than 65 years hospitalized for a TBI from January 1, 2014, through December 31, 2017, and followed for 20 weeks after discharge. Discharges to short-term and long-term acute hospital, inpatient rehabilitation facility (IRF), skilled nursing facility (SNF), long-term nursing home (NH), and hospice were identified. The primary outcome was 90-day community residence. Our secondary outcome was 90-day, all-cause readmission.

RESULTS

In Texas, 26,985 Medicare fee-for-service patients were hospitalized for TBI (Racial and ethnic minorities: 21.1%; Females 57.3%). At 90 days and 20 weeks following discharge, 80% and 84% were living in the community respectively. Female sex (OR = 1.16 [1.08-1.25]), Hispanic ethnicity (OR = 2.01 [1.80-2.25]), "other" race (OR = 2.19 [1.73-2.77]), and prior primary care provider (PCP; OR = 1.51 [1.40-1.62]) were associated with increased likelihood of 90-day community residence. Patients aged 75+, prior NH residence, dual eligibility, prior TBI diagnosis, and moderate-to-severe injury severity were associated with decreased likelihood of 90-day community residence. Being non-Hispanic Black (HR = 1.33 [1.20-1.46]), discharge to SNF (HR = 1.56 [1.48-1.65]) or IRF (HR = 1.49 [1.40-1.59]), having prior PCP (HR = 1.23 [1.17-1.30]), dual eligibility (HR = 1.11 [1.04-1.18]), and prior TBI diagnosis (HR = 1.05 [1.01-1.10]) were associated with increased risk of 90-day readmission. Female sex and "other" race were associated with decreased risk of 90-day readmission.

CONCLUSIONS

Most older adults with TBI return to the community following hospital discharge. Disparities exist in returning to the community and in risk of 90-day readmission following hospital discharge. Future studies should explore how having a PCP influences post-hospital outcomes in chronic care management of older patients with TBI.

Characteristics Associated With Mexican-American Hospice Use: Retrospective Cohort Study Using the Hispanic Established Population for the Epidemiologic Study of the Elderly (H-EPESE)

BACKGROUND

Hospice use is lower among ethnic/racial minorities in the United States, though little is known about trends, associated factors and duration of hospice use by Mexican-Americans.

AIM

The purpose of this study is to examine Mexican-American characteristics associated with hospice stay, both ≤ and > 7 days.

DESIGN

This retrospective cohort study used data from the Hispanic Established Population for the Epidemiological Study of the Elderly (H-EPESE) and the Centers for Medicare and Medicaid Services. Multivariate logistic regression models were used to estimate the ORs and 95% CIs for hospice stay among Mexican-Americans, both ≤ and > 7 days.

SETTING AND PARTICIPANTS

The first cohort (N = 970) includes H-EPESE participants who died between 2004 and 2016 who had Medicare parts A and B. The second cohort (N = 403) includes participants who completed the H-EPESE survey within the last 2 years of life.

RESULTS

Although hospice use increased among Mexican-Americans between 2004 and 2016 (OR 1.88, 95% CI 1.19-2.97), 38% of participants died within the first week of hospice care. Mexican-Americans in New Mexico and Arizona were 2-4 times more likely to use hospice than those in Texas and Colorado. Dementia was associated with hospice use (OR 1.47, 95% CI 1.11-1.94). Characteristics, like church attendance and living alone, were not associated with hospice use.

CONCLUSIONS

The substantial proportion of Mexican-Americans with 7 days or less of hospice use underscores the need for early palliative/hospice intervention to mitigate variation in use.

Metformin and testosterone replacement therapy inversely associated with hormone-associated cancers (prostate, colorectal and male breast cancers) among older White and Black men

BACKGROUND

The independent and joint association of metformin and testosterone replacement therapy (TTh) with the incidence of prostate, colorectal, and male breast cancers remain poorly understood, including the investigation of the risk of these cancers combined (HRCs, hormone-associated cancers) among men of different racial and ethnic background.

METHODS

In 143,035 men (≥ 65 yrs old) of SEER-Medicare 2007-2015, we identified White (N = 110,430), Black (N = 13,520) and Other Race (N = 19,085) men diagnosed with incident HRC. Pre-diagnostic prescription of metformin and TTh was ascertained for this analysis. Weighted multivariable-adjusted conditional logistic and Cox proportional hazards models were conducted.

RESULTS

We found independent and joint associations of metformin and TTh with incident prostate (odds ratio [OR]joint  = 0.44, 95% confidence interval [CI]: 0.36-0.54) and colorectal cancers (ORjoint  = 0.47, 95% CI: 0.34-0.64), but not with male breast cancer. There were also inversed joint associations of metformin and TTh with HRCs (ORjoint  = 0.45, 95% CI: 0.38-0.54). Similar reduced associations with HRCs were identified among White, Black, and Other Race men.

CONCLUSION

Pre-diagnostic use of metformin and TTh were, independently and jointly, inversely associated with incident prostate and colorectal cancers. The risk of HRCs was also reduced among White, Black and Other Race men. Greatest reduced associations of prostate and colorectal cancers and HRCs were mainly observed in combination of metformin and TTh. Larger studies are needed to confirm the independent and joint association of metformin plus TTh with these cancers in understudied and underserved populations.

The Influence of Prior Functional Status on Self-Care Improvement During a Skilled Nursing Facility Stay

OBJECTIVES

Older adults' prior health status can influence their recovery after a major illness. We investigated the association between older adults' independence in self-care tasks prior to a skilled nursing facility (SNF) stay and their self-care function at SNF admission, discharge, and the change in self-care function during an SNF stay.

DESIGN

Retrospective study of 100% national CMS data files from October 1, 2018, to December 31, 2019.

SETTINGS AND PARTICIPANTS

The sample included 616,073 Medicare fee-for-service beneficiaries who were discharged from an SNF between October 1, 2018, and December 31, 2019.

METHODS

The admission Minimum Data Set (MDS) was used to determine residents' prior ability (independent, some help, dependent) to complete self-care tasks before the current illness, exacerbation, or injury. Seven self-care tasks from MDS Section GG were used to calculate total scores (range 7-42 points) for self-care at admission, discharge, and the change in self-care between admission and discharge.

RESULTS

Most residents (62.0%) were independent, 35.3% needed some help, and 2.64% were dependent in self-care prior to SNF admission. Nearly 25% of residents with urinary incontinence, 28.8% with bowel incontinence, and 31.7% with moderate-severe cognitive impairment were independent in self-care prior to SNF admission compared with approximately 70% of residents without these conditions. Compared with residents who were dependent in self-care prior to SNF admission, those who were independent or needed some help had significantly higher self-care total scores at admission (5.67 vs 4.21 points, respectively) and discharge (6.44 vs 3.82 points, respectively) and exhibited greater improvement in self-care (3.48 vs 1.62 points, respectively).

CONCLUSIONS AND IMPLICATIONS

Our findings are evidence that the new MDS item for a resident's independence in self-care tasks before SNF admission is a valid measure of their prior self-care function. This is clinically useful information and should be considered when developing rehabilitation goals.

Deep learning-based NLP data pipeline for EHR-scanned document information extraction

Objective

Scanned documents in electronic health records (EHR) have been a challenge for decades, and are expected to stay in the foreseeable future. Current approaches for processing include image preprocessing, optical character recognition (OCR), and natural language processing (NLP). However, there is limited work evaluating the interaction of image preprocessing methods, NLP models, and document layout.

Materials and Methods

We evaluated 2 key indicators for sleep apnea, Apnea hypopnea index (AHI) and oxygen saturation (SaO2), from 955 scanned sleep study reports. Image preprocessing methods include gray-scaling, dilating, eroding, and contrast. OCR was implemented with Tesseract. Seven traditional machine learning models and 3 deep learning models were evaluated. We also evaluated combinations of image preprocessing methods, and 2 deep learning architectures (with and without structured input providing document layout information), with the goal of optimizing end-to-end performance.

Results

Our proposed method using ClinicalBERT reached an AUROC of 0.9743 and document accuracy of 94.76% for AHI, and an AUROC of 0.9523 and document accuracy of 91.61% for SaO2.

Discussion

There are multiple, inter-related steps to extract meaningful information from scanned reports. While it would be infeasible to experiment with all possible option combinations, we experimented with several of the most critical steps for information extraction, including image processing and NLP. Given that scanned documents will likely be part of healthcare for years to come, it is critical to develop NLP systems to extract key information from this data.

Conclusion

We demonstrated the proper use of image preprocessing and document layout could be beneficial to scanned document processing.

Trends and variation in benzodiazepine use in nursing homes in the USA

PURPOSE

Because of toxicities, benzodiazepines are not usually recommended in older adults. We therefore sought to describe the trends in benzodiazepine use in long-term care and examine the variation in benzodiazepine use among nursing homes.

METHODS

In this retrospective repeated cross-sectional analysis of Medicare Parts A, B, and D claims data linked to the Minimum Data Set from 2013 to 2018, we included long-term residents who stayed in a nursing home for at least one entire quarter of a calendar year in 2013-2018. The outcome was whether residents were prescribed a benzodiazepine drug for at least 30 days during each quarter stay. We use mixed effects logistic regression models to assess the variation in benzodiazepine use among nursing homes, adjusting for patient and nursing home characteristics.

RESULTS

The cohort for the time trend analysis included 270,566 unique residents and 1,843,580 quarter stays for 2013-2018. Prescribing rates for short-acting benzodiazepines were stable over 2013-2016, then declined from 12.1% in 2016 to 10.6% in 2018. The rate of long-acting benzodiazepine use remained relatively steady at around 4% over 2013-2018. During 2017-2018, the variation among nursing homes in benzodiazepine use was 7.2% for short-acting vs. 9.3% for long-acting benzodiazepines, after controlling for resident characteristics.

CONCLUSION

Prescribing for short-acting benzodiazepines in long-term care declined after 2016, while long-acting benzodiazepine use did not change. The variation in benzodiazepine use among nursing homes is substantial. Identifying factors that explain this variation may help in developing strategies for deprescribing benzodiazepines in nursing home residents.

More than two-dozen prescription drug-based risk scores are available for risk adjustment: A systematic review

OBJECTIVE

While several prescription drug-based risk indices have been developed, their design, performance, and application has not previously been synthesized.

STUDY DESIGN AND SETTING

We searched Ovid MEDLINE, CINAHL and Embase from inception through March 3, 2020 and included studies that developed or updated a prescription drug-based risk index. Two reviewers independently performed screening and extracted information on data source, study population, cohort sizes, outcomes, study methodology and performance. Predictive performance was evaluated using C statistics for binary outcomes and R² for continuous outcomes. The PROSPERO ID for this review is CRD42020165498.

RESULTS

Of 19,112 articles that were retrieved, 124 were full-text screened and 25 were included, each of which represented a de novo or updated drug-based index. The indices were customized to varied age groups and clinical populations and most commonly evaluated outcomes including mortality (36%), hospitalization (24%) and healthcare costs (24%). C statistics ranged from 0.62 to 0.92 for mortality and 0.59 to 0.72 for hospitalization, while adjusted R² for healthcare costs ranged from 0.06 to 0.62. Seven of the 25 risk indices included used global drug classification algorithms.

CONCLUSIONS

More than two-dozen prescription drug-based risk indices have been developed and they differ significantly in design, performance and application.

Decrease of Anticholinergic Drug Use in Nursing Home Residents in the United States, 2009 to 2017

OBJECTIVE

To investigate the time course of anticholinergic drug use in nursing home residents and assess if any temporal change in anticholinergic use varied by nursing home quality rating.

DESIGN

Retrospective repeated cross-sectional analysis of Medicare enrollment, Parts A, B, and D, claims data linked to the Minimum Data Set from 2009 to 2017.

SETTING

Medicare-certified nursing homes.

PARTICIPANTS

Long-term residents 65 years or older with nursing home stay of at least 100 consecutive days within a given calendar year.

MEASUREMENTS

Estimates of anticholinergic drug prescription rates between 2009 and 2017 were based on a binary variable indicating whether a resident received a drug with high anticholinergic activity, as defined by the Anticholinergic Cognitive Burden scale, for at least 1 day during the initial 100 consecutive days of nursing home stay in a given calendar year. We used mixed effects logistic regression models to determine adjusted rates of anticholinergic use each year and test the interaction between nursing home quality rating and year, while adjusting for patient and nursing home characteristics.

RESULTS

The cohort included 786,858 100-day nursing home stays (299,354 unique residents) in 6,703 nursing homes for the years 2009 to 2017. Prescription rates were stable at approximately 34% to 35% between 2009 and 2011, then gradually decreased to 24.3% in 2017 (P < .0001), with the decline being more pronounced in nursing homes having high quality ratings (P < .0001). Rates for anticholinergic drugs in nursing homes with 4 to 5 star quality rating (33.7% in 2011 to 23.3% in 2017) showed a steeper decline over time relative to nursing homes with 1 to 2 star quality rating (34.2% in 2011 to 25.2% in 2017) (P < .0001).

CONCLUSIONS

The use of drugs with high anticholinergic activity has declined from 2009 to 2017, with a greater decline in higher-quality nursing homes.

Suppression of DNA/RNA and protein oxidation by dietary supplement which contains plant extracts and vitamins: a randomized, double-blind, placebo-controlled trial

Background

Excessive oxidative stress may impair bio-molecules and cellular function. Multi antioxidant supplementation is thought to be more effective than a single antioxidant probably through the synergistic or complementary action of natural substances that could enhance the prospective effect.

Methods

In order to estimate the effect of a plant extract based supplement in apparently healthy volunteers’ oxidative stress markers, a double-blind and placebo controlled intervention was performed. 62 apparently healthy volunteers, overweight with medium adherence to the Mediterranean diet, were recruited and randomly allocated into two intervention groups (supplement or placebo) for 8 weeks. Basic biochemical markers, oxidized LDL (oxLDL), resistance of serum in oxidation, protein carbonyls in serum and 8-isoprostane and DNA/RNA damage in urine were measured.

Results

No differentiation was observed in basic biochemical markers, in oxLDL levels as well as in serum resistance against oxidation, during intervention in the examined groups. A significant resistance regarding urine isoprostanes levels in the supplement group compared to the placebo one, was observed. Reduction on DNA/RNA damage and on protein carbonyls levels (almost 30% and 20% respectively, at 8 weeks) was detected in volunteers who consumed the supplement compared to the control group.

Conclusion

Consumption of plant extract based supplement seems to reduce DNA/RNA and protein oxidation and in less extent lipids peroxidation.

Brown adipose tissue is associated with systemic concentrations of peptides secreted from the gastrointestinal system and involved in appetite regulation

OBJECTIVE

Brown adipose tissue (BAT) has been proposed as a potential therapeutic target against obesity and its related metabolic conditions. Data from studies in rodents support a cross talk between BAT and other distal tissues. The relation between BAT and peptide hormones secreted from the gastrointestinal system (GI) and involved in appetite regulation is not known in humans.

DESIGN

We studied 18 men during thermoneutral conditions and mild non-shivering cold exposure (CE).

METHODS

2-Deoxy-2-(¹⁸F)fluoro-d-glucose positron emission tomography-computed tomography scans were conducted after mild cold to measure BAT volume. Fasting serum concentration of GI-secreted peptides and peptides involved in appetite regulation were measured during thermoneutral conditions and mild CE.

RESULTS

During thermoneutral conditions, BAT volume was associated with lower serum concentration of leptin (P = 0.006), gastric inhibitory polypeptide (P = 0.016) and glucagon (P = 0.048) after adjusting for age and body fat percent. CE significantly decreased serum leptin (P = 0.004) and glucagon concentration (P = 0.020), while cold-induced BAT activation was significantly associated with lower serum ghrelin concentration (P = 0.029).

CONCLUSIONS

BAT is associated with systemic concentrations of GI-secreted peptides and peptides involved in appetite regulation, suggesting a potential cross talk between BAT and the enteropancreatic axis. Further studies are needed to elucidate the potential link of BAT with the postprandial levels of appetite-regulating peptides and the putative role of BAT in appetite regulation in humans.

Brown Adipose Tissue Is Linked to a Distinct Thermoregulatory Response to Mild Cold in People

Brown adipose tissue (BAT) plays an important role in thermoregulation in rodents. Its role in temperature homeostasis in people is less studied. To this end, we recruited 18 men [8 subjects with no/minimal BAT activity (BAT−) and 10 with pronounced BAT activity (BAT+)]. Each volunteer participated in a 6 h, individualized, non-shivering cold exposure protocol. BAT was quantified using positron emission tomography/computed tomography. Body core and skin temperatures were measured using a telemetric pill and wireless thermistors, respectively. Core body temperature decreased during cold exposure in the BAT− group only (−0.34°C, 95% CI: −0.6 to −0.1, p = 0.03), while the cold-induced change in core temperature was significantly different between BAT+ and BAT− subjects (BAT+ vs. BAT−, 0.43°C, 95% CI: 0.20–0.65, p = 0.0014). BAT volume was associated with the cold-induced change in core temperature (p = 0.01) even after adjustment for age and adiposity. Compared to the BAT− group, BAT+ subjects tolerated a lower ambient temperature (BAT−: 20.6 ± 0.3°C vs. BAT+: 19.8 ± 0.3°C, p = 0.035) without shivering. The cold-induced change in core temperature (r = 0.79, p = 0.001) and supraclavicular temperature (r = 0.58, p = 0.014) correlated with BAT volume, suggesting that these non-invasive measures can be potentially used as surrogate markers of BAT when other methods to detect BAT are not available or their use is not warranted. These results demonstrate a physiologically significant role for BAT in thermoregulation in people. This trial has been registered with Clinaltrials.gov: NCT01791114 (https://clinicaltrials.gov/ct2/show/NCT01791114).

Is the heat surrounding adipose tissue mitochondria warranted?

PURPOSE OF REVIEW

Mitochondrial uncoupling proteins uncouple oxidative phosphorylation. The physiological role ascribed to this process is thermoregulation. The metabolic consequence of mitochondrial respiration uncoupled from ATP production is increased substrate oxidation and metabolic rate. The recent discovery of uncoupling protein 1 (UCP1) positive mitochondria in human adipose tissue has rekindled interest in the role of UCP1 in energy balance and metabolic health.

RECENT FINDINGS

Recently, there have been numerous reports of functional brown adipose tissue in humans. Further, data from cell and murine studies suggest that beige adipocytes can be induced within white adipose tissue. The presence of brown/beige adipocytes with mitochondria expressing UCP1 negatively correlates with adiposity. Further, activation of these adipocytes alters energy balance and substrate metabolism. However, in humans, brown fat content varies significantly. Further, although beige adipocytes can be induced in white adipose tissue of rodents, whether this is also true in humans remains unclear.

SUMMARY

The presence of UCP1-positive mitochondria in human adipose tissue represents an exciting therapeutic target for treating obesity and its metabolic complications. Understanding the mechanisms governing brown fat activation will be crucial if the therapeutic potential of UCP1 is to be realized.

A dietary pattern characterized by high consumption of whole-grain cereals and low-fat dairy products and low consumption of refined cereals is positively associated with plasma adiponectin levels in healthy women

In light of the potential beneficial effects of adiponectin on insulin resistance, metabolic syndrome, and cardiovascular risk, it is becoming increasingly important to identify all modifiable factors, including dietary patterns, that may affect circulating adiponectin concentrations. The aim of the present study was to explore potential associations between dietary patterns and plasma adiponectin levels using principal component analysis (PCA) in a sample of apparently healthy adult Mediterranean women. Two hundred twenty women were enrolled in this study. Anthropometric and body composition measurements were performed in all subjects. Blood samples were taken, and adiponectin concentrations were measured. Food intake was evaluated by 3-day food diaries, and PCA was used for the identification of the participants' dietary patterns. The PCA identified 10 dietary components explaining 82% of the total variance in food intake. Bivariate correlation between circulating adiponectin levels and dietary components revealed a positive significant association only with the first component that was characterized by high intake of whole-grain cereals and low-fat dairy products as well as low intake of refined cereals (P = .04). This association remained unchanged after controlling for potential confounders (standardized beta coefficient = 0.18, P = .03). A dietary pattern characteristic of consumption of alcoholic beverages was found to be marginally related to adiponectin levels in the multivariate model (standardized beta coefficient = 0.14, P = .10). Our data indicate that a dietary pattern characterized by a high consumption of whole-grain cereals and low-fat dairy products is modestly positively associated with adiponectin concentrations.

[Incident of CMD in patients with non typical headache]

Headache is a very common symptom related to the craniomandibular disorders. In the last 25 years a remarkable number of research studies have proved the close relation between headache and dysfunction of the stomatognathic system. There has been many classifications of the types of headache but none of them has been accepted by the plurality of clinicians and researchers working on the subject. The commonest headache is the one named "tension/headache". Its frequency and its close relation to the craniomandibular disorders have been the reason for the systemic research of this subject with the cooperation of the neurologic clinic of the NIMTS. The material consisted of 35 patients who had headache as a main disturbance. There has been evaluation of their dysfunction as well as their neurologic condition. The results of the study have proved that a considerable number of these patients had headaches due to craniomandibular dysfunction. We also found out that many people suffer from craniomandibular disorders without knowing it. The results of the present research are according with those of similar studies of the international literature.
