Integration Activities Between Hospitals and Skilled Nursing Facilities: A National Survey

ObjectivesIncreasing recognition of the adverse events older adults experience in post-acute care in skilled nursing facilities (SNFs) has led to multiple efforts to improve care integration between hospitals and SNFs. We sought to measure current care integration activities between hospitals and SNFs.DesignCross-sectional survey.Setting and ParticipantsA total of 500 randomly selected Medicare-certified SNFs in the United States in 2019. The survey inquired about 12 care integration activities with the 2 highest volume referring hospitals for each SNF.MethodsWe collapsed survey responses into 5 categories of integration based on high correlations between the individual measures. These were: (1) formal integration (co-location or co-ownership); (2) informal integration (eg, formal affiliation, participation in SNF collaborative, shared pay for performance, or clinical leadership meetings between hospital and SNF); (3) shared quality/safety activities (eg, initiatives to improve medication safety or reduce hospital admission); (4) shared care coordinators; and/or (5) shared supervising clinicians. We then conducted multivariate regressions to examine associations between different care integration activities and hospital/SNF characteristics.ResultsOur overall response rate was 53.0%, including 265 SNFs that represented 487 SNF-hospital pairs. Informal integration was most common (in 53.3% of pairs), whereas shared clinicians (43.0%), care coordinators (36.5%), shared quality/safety activities (35.1%), and formal integration (7.4%) were present in a minority. Hospital-SNF pairs had lower odds of being formally integrated if the SNF was for-profit compared with not-for-profit [odds ratio (OR) 0.11, 95% confidence interval (CI) 0.03–0.42, adjusted P = .04)] and higher odds of sharing quality improvement activities in metropolitan rather than rural areas (OR 4.06, 95% CI 1.80–9.17, adjusted P = .02) and in the Midwest compared with West (OR 2.95, 95% CI 1.44–6.06, adjusted P = .049).Conclusions and ImplicationsThese findings raise important questions about what is driving variability in hospital-SNF integration activities, and which activities may be most effective for improving transitional care outcomes.     

Transitions Between Frailty States and Its Predictors in a Cohort of Community-Dwelling Spaniards

ObjectivesStudy the frequency and determinants of frailty transitions in a community-dwelling older population.DesignPopulation-based prospective longitudinal study [The Toledo Study of Healthy Ageing (TSHA)].Setting and Participants1748 community-dwelling individuals aged >65 years living in Toledo, a Spanish province.MethodsFrailty was measured with the Fried phenotype. Logistic models were used to assess the associations of sociodemographic, clinical, life-habits, functional, physical performance, and analytical variables with frailty transitions (losing robustness, transitioning from prefrailty to robustness, and from prefrailty to frailty) over a median of 5.2 years.ResultsMean age on enrolment was 75 years, and 55.8% were females. At baseline, 10.3% were frail and 43.1% prefrail. At follow-up, 35.8% of the frail individuals recovered to a prefrail and 15.1% to a robust state. In addition, 43.7% of the prefrail participants became robust, but 14.5% developed frailty. Of those robust at baseline, 32.9% became prefrail and 4.2% frail. In multivariate logistic models, chair-stands had a predictive role in all transitions studied: linearly in keeping robustness and with a floor effect (5 stands) in transitions from prefrailty to robustness and (inversely) from prefrailty to frailty. More depressive symptoms were associated with unfavorable transitions. Not declaring the amount of alcohol drunk and low grip strength were associated with loss of robustness. Hearing and cognitive impairment, low physical activity and smoking with transitioning from prefrailty to frailty. Autonomy for instrumental activities of daily living and uricemia were associated with transitions between robustness and prefrailty in both directions. Increasing body mass index in the range of moderate to severe obesity hampered regaining robustness.Conclusions and ImplicationsSpontaneous improvement of frailty measured with the Fried phenotype is frequent, mainly to prefrailty. Most of the variables associated with transitions are modifiable and suggest research topics and interventions to reduce frailty in clinical and social care settings.     

Formal and Informal Costs of Care for People With Dementia Who Experience a Transition to Hospital at the End of Life: A Secondary Data Analysis

ObjectivesTo explore formal and informal care costs in the last 3 months of life for people with dementia, and to evaluate the association between transitions to hospital and usual place of care with costs.DesignCross-sectional study using pooled data from 3 mortality follow-back surveys.Setting and ParticipantsPeople who died with dementia.MethodsThe Client Service Receipt Inventory survey was used to derive formal (health, social) and informal care costs in the last 3 months of life. Generalized linear models were used to explore the association between transitions to hospital and usual place of care with formal and informal care costs.ResultsA total of 146 people who died with dementia were included. The mean age was 88.1 years (SD 6.0), and 98 (67.1%) were female. The usual place of care was care home for 85 (58.2%). Sixty-five individuals (44.5%) died in a care home, and 85 (58.2%) experienced a transition to hospital in the last 3 months. The mean total costs of care in the last 3 months of life were £31,224.7 (SD 23,536.6). People with a transition to hospital had higher total costs (£33,239.2, 95% CI 28,301.8-39,037.8) than people without transition (£21,522.0, 95% CI 17,784.0-26,045.8), mainly explained by hospital costs. People whose usual place of care was care homes had lower total costs (£23,801.3, 95% CI 20,172.0-28,083.6) compared to home (£34,331.4, 95% CI 27,824.7-42,359.5), mainly explained by lower informal care costs.Conclusions and ImplicationsTotal care costs are high among people dying with dementia, and informal care costs represent an important component of end-of-life care costs. Transitions to hospital have a large impact on total costs; preventing these transitions might reduce costs from the health care perspective, but not from patients' and families' perspectives. Access to care homes could help reduce transitions to hospital as well as reduce formal and informal care costs.     

Behavioural Development in Children of Divorce and Remarriage

We employed an autoregressive modelling technique with data from the Quebec Longitudinal Study to prospectively examine the developmental impact of family transition on behaviour while controlling for predivorce and preremarriage effects. Teachers rated children's anxious, hyperactive, physically aggressive, oppositional, and prosocial behaviour every 2 years from kindergarten through to the end of elementary school.Once individual and parental characteristics and antecedent family events were controlled, children who experienced parental divorce before age 6 exhibited comparatively more behavioural disturbance than their peers whose parents divorced later. With the exception of a protective effect on hyperactive behaviour, remarriage did not have a significant impact on children's behaviour when the legacy of divorce was controlled.Although the results suggest that children of divorced parents show difficulty in many areas of functioning, the effects of family transition on behavioural development were dependent on the child's age and the specific behavioural dimension assessed.Compared to other points in development, early childhood divorce was associated with long-term increases in anxious, hyperactive, and oppositional behaviour during later childhood.The effects of divorce on children's fighting were short-lived.Unlike previous prospective studies that suggest predivorce effects, we did not observe behavioural disturbance prior to divorce or remarriage.     

Differences in the Scalability of Formal and Informal In-Home Care of Urban Elderly

Differences in the scalability of formal and informal in-home care to elderly are examined. A Guttman scale showed that exclusive use of informal in-home care was hierarchically scalable, but not when services were provided by any formal sources. There was some clustering of formal services, for example, a large number of those who received meals also used homemaker services. However, a large number of those who received nursing did not receive personal care. There was no overall pattern to the use of formal services. Implications of these findings as related to service planning and delivery are discussed.     

Trauma exposure,incident psychiatric disorders,and disorder transitions in a longitudinal population representative sample

Heterotypic continuity, whereby individuals transition from one disorder to another, is common; however, longitudinal studies examining transdiagnostic predictors of heterotypic continuity are lacking. The current study examined whether trauma exposure during childhood (maltreatment) and adulthood (interpersonal and non-interpersonal trauma) is associated with heterotypic continuity in a national sample. Men and women (N = 34,653) who participated in Waves 1 (2001–2002) and 2 (2004–2005) of the National Survey of Alcohol and Related Conditions (NESARC) completed face-to-face interviews about trauma exposure and psychopathology. Risk ratios and population attributable risk proportions (PARPs) quantified the effects of childhood maltreatment and interpersonal and non-interpersonal trauma exposure between Waves 1 and 2 on risk for incident disorders and transitions between specific types of disorders. Twenty percent of respondents reported a Wave 2 incident disorder. Those with any Wave 1 disorder were at increased risk of incident mood (RR range = 1.2–2.1) and anxiety (RR = 1.5–2.7) disorders at Wave 2. Child maltreatment and interpersonal trauma exposure since Wave 1 were associated with roughly 50% of the risk for disorder transitions (RR range = 1.2–2.7); non-interpersonal trauma was associated with 30% of the risk for disorder transitions (RR range = 1.0–1.7). Findings suggest that new onset disorders were common in U.S. adults and trauma exposure explained a large proportion of disorder incidence as well as progression from one disorder to another. Universal prevention efforts that begin early in life, rather than those targeted at specific disorders, would be fruitful for reducing the burden of population mental health and preventing a cascade of mental disorders over the life course.     

Removal of Polymeric Plutonium from Mice by Combined Therapy with the Calcium Chelate and Penta-ethyl Ester of DTPA

Summary

C57BL/6 mice were exposed to either ionizing radiation or actinomycin at the peak and nadir of jejunal crypt cell mitotic activity. Animals exposed at the peak were more sensitive than animals exposed at the nadir. Conversely, animals treated with actinomycin D were slightly more sensitive at the nadir. These observations suggest that studies of the combined lethal effects of ionizing radiation and actinomycin D may be complicated by the change in sensitivity of normal tissues to either treatment under the influence of a circadian variable.

Working Without a Net: Leukemia and Lymphoma Survivors’ Perspectives on Care Delivery at End-of-Treatment and Beyond

This study explored survivors’ perspectives on care delivery and supportive care needs during reentry. Fifty-one individual interviews were conducted with adult leukemia and lymphoma survivors, 3 to 48 months from treatment cessation. Survivors reported poor continuity of care across the patient–survivor transition, difficulty finding appropriate information/services, lack of preparation, lack of support for survivorship issues, and inadequate or poorly timed follow-up as factors contributing to adjustment difficulties at end of treatment and beyond. Improved care coordination is needed after active treatment, including use of an exit interview and delivery of services that are more congruent and better timed to meet ongoing and emergent survivorship needs.
