Nursing home medical staff organization and 30-day rehospitalizations

Interprofessional relationships and their impact on resident hospitalizations in nursing homes: A qualitative study

AIM

The aim of this study is to explore experiences and perspectives of nurses and providers (e.g., physicians, medical directors, fellows, and nurse practitioners) on reducing preventable hospitalizations of nursing home (NH) residents in relation to interprofessional relationship and hospitalization decision-making process.

BACKGROUND

Preventable NH resident hospitalization continues to be a pressing public health issue. Studies show that improved interprofessional relationship may help reduce hospitalization, yet research on communication processes and interactions among different NH staff remains limited.

METHODS

This is a qualitative descriptive study. Two focus groups were held with fourteen nurses and thirteen in-depth, qualitative interviews were conducted with providers from two Chicagoland NHs. Focus group sessions and interviews were transcribed, coded, and analyzed for common themes based on qualitative description method.

RESULTS

All study participants agreed that providers have the ultimate responsibility for hospitalization decisions. However, nurses believed they could influence those decisions, depending on provider characteristics, trust, and resident conditions. Nurses and providers differed in the way they experienced and conveyed emotions, and differed in key elements affecting hospitalization decisions such as structural or environmental factors (e.g., lacking staff and equipment at the facility, poor communication between the NH and hospitals) and interpersonal factors (e.g., characteristics of effective nurses or providers and the effective interactions between them).

CONCLUSIONS

Interpersonal factors, including perceived competence, respect, and trust, may influence NH hospitalization decisions and be targeted for reducing preventable hospitalizations of residents.

Changing landscape of nursing homes serving residents with dementia and mental illnesses

OBJECTIVE

Nursing homes (NHs) are serving an increasing proportion of residents with cognitive issues (e.g., dementia) and mental health conditions. This study aims to: (1) implement unsupervised machine learning to cluster NHs based on residents' dementia and mental health conditions; (2) examine NH staffing related to the clusters; and (3) investigate the association of staffing and NH quality (measured by the number of deficiencies and deficiency scores) in each cluster.

DATA SOURCES

2009-2017 Certification and Survey Provider Enhanced Reporting (CASPER) were merged with LTCFocUS.org data on NHs in the United States.

STUDY DESIGN

Unsupervised machine learning algorithm (K-means) clustered NHs based on percent residents with dementia, depression, and serious mental illness (SMI, e.g., schizophrenia, anxiety). Panel fixed-effects regressions on deficiency outcomes with staffing-cluster interactions were conducted to examine the effects of staffing on deficiency outcomes in each cluster.

DATA EXTRACTION METHODS

We identified 110,463 NH-year observations from 14,671 unique NHs using CASPER data.

PRINCIPAL FINDINGS

Three clusters were identified: low dementia and mental illnesses (Postacute Cluster); high dementia and depression, but low SMI (Long-stay Cluster); and high dementia and mental illnesses (Cognitive-mental Cluster). From 2009 to 2017, the number of Postacute Cluster NHs increased from 3074 to 5719, while the number of Long-stay Cluster NHs decreased from 6745 to 3058. NHs in Long-stay/Cognitive-mental Clusters reported slightly lower nursing staff hours in 2017. Regressions suggested the effect of increasing staffing on reducing deficiencies is statistically similar across NH clusters. For example, 1 hour increase in registered nurse hours per resident day was associated with -0.67 (standard error [SE] = 0.11), -0.88 (SE = 0.12), and -0.97 (SE = 0.15) deficiencies in Postacute Cluster, Long-stay Cluster, and Cognitive-mental Cluster, respectively.

CONCLUSIONS

Unsupervised machine learning detected a changing landscape of NH serving residents with dementia and mental illnesses, which requires assuring staffing levels and trainings are suited to residents' needs.

Individualized Medication Management in Ontario Long-Term Care Clinical Impact on Management of Depression, Pain, and Dementia

OBJECTIVES

Assess the potential benefits of identifying drug-gene interactions in nursing home (NH) residents on multiple medications. Reduce the use of high-risk medications for residents with reduced drug metabolism.

DESIGN

Open-label, nonrandomized, mixed methods study.

SETTING

Four NHs in Ontario.

MEASUREMENTS

Potential drug therapy problems (DTPs) for study cohort were identified during a medication review by a pharmacist using pharmacogenetic (PGx) clinical decision support to identify medication change opportunities. The number of DTPs identified during a standard medication review was compared with the number of DTPs identified with a PGx clinical decision support. Analysis of medication dispensing data at enrollment compared with dispensing in a 60-day window following medication review were compared for the PGx-tested study cohort with controls.

RESULTS

Prescription patterns of 90 study participants were compared with 895 controls for the same time period. Study participants were on 7 to 47 drugs, of which drugs with PGx indications ranged from 1 to 17 medications. The average medication load was 4.6 medications with PGx indications per person, whereas the controls were on 3.5 PGx drugs. Furthermore, 94% of cases and 84% of controls were on 2 or more drugs with PGx indication during the study period. Pharmacogenetic analysis identified 114 distinct DTPs in the 90 study participants, of which 29 were classified as serious. In this study, over 35% of residents were treated with antidepressants; of these, 64% have altered CYP2C19 or CYP2D6 metabolism and could benefit from drug dose adjustment or from a switch to alternative antidepressants. Twenty percent of residents were treated with hydromorphone, of which 30% have reduced response to opioids because of variations in the OPRM1 gene.

CONCLUSIONS AND IMPLICATIONS

This study demonstrated the clinical potential of PGx-based medication optimization for NH residents, impacting the management of depression, chronic pain, heart disease, and gastrointestinal symptoms.

Medical Care Delivery in U.S. Nursing Homes: Current and Future Practice

The delivery of medical care services in U.S. nursing homes (NHs) is dependent on a workforce that comprises physicians, nurse practitioners, and physician assistants. Each of these disciplines operates under a unique regulatory framework while adhering to common standards of care. NH provider characteristics and their roles in NH care can illuminate potential links to clinical outcomes and overall quality of care with important policy and cost implications. This perspective provides an overview of what is currently known about medical provider practice in NH and organizational models of practice. Links to quality, both conceptual and established, are presented as is a research and policy agenda that addresses the gaps in the evidence base within the context of our ever-changing health care landscape.

Proceedings from an International Virtual Townhall: Reflecting on the COVID-19 Pandemic: Themes from Long-Term Care

Residents of long-term care (LTC) homes have suffered disproportionately during the COVID-19 pandemic, from the virus itself and often from the imposition of lockdown measures. Provincial Geriatrics Leadership Ontario, in collaboration with interRAI and the International Federation on Aging, hosted a virtual Town Hall on September 25, 2020. The purpose of this event was to bring together international perspectives from researchers, clinicians, and policy experts to address important themes potentially amenable to timely policy interventions. This article summarizes these themes and the ensuing discussions among 130 attendees from 5 continents. The disproportionate impact of the COVID-19 pandemic on frail residents of LTC homes reflects a systematic lack of equitable prioritization by health system decision makers around the world. The primary risk factors for an outbreak in an LTC home were outbreaks in the surrounding community, high staff and visitor traffic in large facilities, and crowding of residents in ageing buildings. Infection control measures must be prioritized in LTC homes, though care must be taken to protect frail and vulnerable residents from their overly blunt application that deprives residents from appropriate physical and psychosocial support. Staffing, in terms of overall numbers, training, and leadership skills, was inadequate. The built environment of LTC homes can be configured for both optimal resident well-being and infection control. Infection control and resident wellness need not be mutually exclusive. Improving outcomes for LTC residents requires more staffing with proper training and interprofessional leadership. All these initiatives must be underpinned by an effective quality assurance system based on standardized, comprehensive, accessible, and clinically relevant data, and which can support broad communities of practice capable of effecting real and meaningful change for frail older persons, wherever they chose to reside.

Long-Term Care Facility Ownership and Acute Hospital Service Use in British Columbia, Canada: A Retrospective Cohort Study

OBJECTIVE

Previous studies report higher hospitalization rates in for-profit compared with nonprofit long-term care facilities (LTCFs), but have not included staffing data, a major potential confounder. Our objective was to examine the effect of ownership on hospital admission rates, after adjusting for facility staffing levels and other facility and resident characteristics, in a large Canadian province (British Columbia).

DESIGN

Retrospective cohort study.

SETTING AND PARTICIPANTS

Our cohort included individuals resident in a publicly funded LTCF in British Columbia at any time between April 1, 2012 and March 31, 2016.

MEASURES

Health administrative data were extracted from multiple databases, including continuing care, hospital discharge, and Minimum Data Set (MDS 2.0) assessment records. Cox extended hazards regression was used to estimate hospitalization risk associated with facility- and resident-level factors.

RESULTS

The cohort included 49,799 residents in 304 LTCF facilities (116 publicly owned and operated, 99 for-profit, and 89 nonprofit) over the study period. Hospitalization risk was higher for residents in for-profit (adjusted hazard ratio [adjHR] 1.34; 95% confidence interval [CI] 1.29-1.38) and nonprofit (adjHR 1.37; 95% CI 1.32-1.41) facilities compared with publicly owned and operated facilities, after adjustment for staffing, facility size, urban location, resident demographics, and case mix. Within subtypes, risk was highest in single-site facilities: for-profit (adjHR 1.42; 95% CI 1.36-1.48) and nonprofit (adjHR 1.38, 95% CI 1.33-1.44).

CONCLUSIONS AND IMPLICATIONS

This is the first Canadian study using linked health data from hospital discharge records, MDS 2.0, facility staffing, and ownership records to examine the adjusted effect of facility ownership characteristics on hospital use of LTCF residents. We found significantly lower adjHRs for hospital admission in publicly owned facilities compared with both for-profit and nonprofit facilities. Our finding that publicly owned facilities have lower hospital admission rates compared with for-profit and nonprofit facilities can help inform decision-makers faced with the challenge of optimizing care models in both nursing homes and hospitals as they build capacity to care for aging populations.

Non-ventilator health care-associated pneumonia (NV-HAP): Long-term care

Nonventilator health care-associated pneumonia (NV-HAP) is costly and preventable with significant impact on patient morbidity and mortality. This chapter outlines the increased risk of NV-HAP among individuals residing in long-term care facilities and the incidence of pneumonia in this health care setting which accounts for up to 18% of all persons admitted to acute care hospital for pneumonia. A description of prevention strategies with detail on modifiable and Nonmodifiable risk factors for acquiring pneumonia are presented along with the need for a robust interdisciplinary team and approach for this vulnerable population. In addition, the lack of active surveillance and infection prevention expertise may result in the spread of pathogens that can cause NVHAP outbreaks.

Postacute care outcomes and medicare payments for patients treated by physicians and advanced practitioners who specialize in nursing home practice

OBJECTIVE

To measure the association between clinician specialization in nursing home (NH) practice and outcomes of patients who received postacute care in skilled nursing facilities (SNFs).

DATA SOURCES

Medicare claims and NH assessments for 2 118 941 hospital discharges to 14 526 SNFs in January 2012-October 2014 and MD-PPAS data for 52 379 clinicians.

STUDY DESIGN

Generalist physicians and advanced practitioners with ≥ 90 percent of claims for NH-based care were considered NH specialists. The primary clinician during each SNF stay was determined based on plurality of claims during that stay. We estimated the effect of being treated by a NH specialist on 30-day rehospitalizations, successful discharge to community, and 60-day episode-of-care Medicare payments (Parts A and B). All models included patient demographics, clinical variables, and SNF fixed effects.

PRINCIPAL FINDINGS

Nursing home specialists' patients were less likely to be rehospitalized (14.71 percent vs 16.23 percent; adjusted difference, -1.51 percent, 95% CI -1.78 to -1.24), more likely to be successfully discharged to community (56.33 percent vs 55.49 percent; adjusted difference, 0.84 percent, 95% CI 0.54 to 1.14), but had higher 60-day Medicare payments ($31 628 vs $31 292; adjusted difference, $335; 95% CI $242 to $429).

CONCLUSIONS

Clinicians who specialize in NH practice may achieve better postacute care outcomes at slightly higher costs.

An International Mapping of Medical Care in Nursing Homes

Nursing home (NH) residents are increasingly in need of timely and frequent medical care, presupposing not only available but perhaps also continual medical care provision in NHs. The provision of this medical care is organized differently both within and across countries, which may in turn profoundly affect the overall quality of care provided to NH residents. Data were collected from official legislations and regulations, academic publications, and statistical databases. Based on this set of data, we describe and compare the policies and practices guiding how medical care is provided across Canada (2 provinces), Germany, Norway, and the United States. Our findings disclose that there is a considerable difference to find among jurisdictions regarding specificity and scope of regulations regarding medical care in NHs. Based on our data, we construct 2 general models of medical care: (1) more regulations-fee-for-service payment-open staffing models and (2) less regulation-salaried positions-closed staffing models. Some evidence indicates that model 1 can lead to less available medical care provision and to medical care provision being less integrated into the overall care services. As such, we argue that the service models discussed can significantly influence continuity of medical care in NH.

Reducing Inpatient Hospital and Emergency Room Utilization Among Nursing Home Residents

OBJECTIVE

To examine the association among nursing home residents between strength of relationship with a primary care provider (PCP) and inpatient hospital and emergency room (ER) utilization.

METHOD

Medicare administrative data for beneficiaries residing in a nursing home between July 2007 and June 2009 were used in multivariate analyses controlling for beneficiary, nursing home, and market characteristics to assess the association between two measures-percentage of months with a PCP visit and whether the patient maintained the same usual source of care after nursing home admission-and hospital admissions and ER visits for all causes and for ambulatory care sensitive conditions (ACSCs).

RESULTS

Both measures of strength of patient-provider relationships were associated with fewer inpatient admissions and ER visits, except regularity of PCP visits and ACSC ER visits.

DISCUSSION

Policy makers should consider increasing the strength of nursing home resident and PCP relationships as one strategy for reducing inpatient and ER utilization.

Facility characteristics as independent prognostic factors of nursing home-acquired pneumonia

BACKGROUND/AIMS

Recently, the incidence of nursing home-acquired pneumonia (NHAP) has been increasing and is now the leading cause of death among nursing home residents. This study was performed to identify risk factors associated with NHAP mortality, focusing on facility characteristics.

METHODS

Data on all patients ≥ 70 years of age admitted with newly diagnosed pneumonia were reviewed. To compare the quality of care in nursing facilities, the following three groups were defined: patients who acquired pneumonia in the community, care homes, and care hospitals. In these patients, 90-day mortality was compared.

RESULTS

Survival analyses were performed in 282 patients with pneumonia. In the analyses, 90-day mortality was higher in patients in care homes (12.2%, 40.3%, and 19.6% in community, care homes, and care hospitals, respectively). Among the 118 NHAP patients, residence in a care home, structural lung diseases, treatment with inappropriate antimicrobial agents for accompanying infections, and a high pneumonia severity index score were risk factors associated with higher 90-day mortality. However, infection by potentially drug-resistant pathogens was not important.

CONCLUSIONS

Unfavorable institutional factors in care homes are important prognostic factors for NHAP.

A cluster randomized controlled trial comparing relative effectiveness of two licensed influenza vaccines in US nursing homes: Design and rationale

BACKGROUND

Influenza, the most important viral infection affecting older adults, produces a substantial burden in health care costs, morbidity, and mortality. Influenza vaccination remains the mainstay in prevention and is associated with reduced rates of hospitalization, stroke, heart attack, and death in non-institutional older adult populations. Influenza vaccination produces considerably lower antibody response in the elderly compared to young adults. Four-fold higher vaccine antigen (high-dose) than in the standard adult vaccine (standard-dose) elicits higher serum antibody levels and antibody response in ambulatory elderly.

PURPOSE

To describe the design considerations of a large clinical trial of high-dose compared to standard-dose influenza vaccine in nursing homes and baseline characteristics of participating nursing homes and long-stay (more than 90 days) residents over 65 years of age.

METHODS

The high-dose influenza vaccine intervention trial is multifacility, cluster randomized controlled trial with a 2×2 factorial design that compares hospitalization rates, mortality, and functional decline among long-stay nursing home residents in facilities randomized to receive high-dose versus standard-dose influenza vaccine and also randomized with or without free staff vaccines provided by study organizers. Enrollment focused on nursing homes with a large long-stay resident population over 65 years of age. The primary outcome is the resident-level incidence of hospitalization with a primary diagnosis of pulmonary and influenza-like illness, based upon Medicare inpatient hospitalization claims. Secondary outcomes are all-cause mortality based upon the vital status indicator in the Medicare Vital Status file, all-cause hospitalization directly from the nursing home Minimum Data Set discharge records, and the probability of declining at least 4 points on the 28-point Activities of Daily Living Scale.

RESULTS

Between February and September 2013, the high-dose influenza vaccine trial recruited and randomized 823 nursing homes. The analysis sample includes 53,035 long-stay nursing home residents over 65 years of age, representing 57.7% of the participating facilities' population. Residents are mainly women (72.2%), white (75.5%), with a mean age of 83 years. Common conditions include hypertension (79.2%), depression (55.1%), and diabetes mellitus (34.4%). The prevalence of circulatory and pulmonary disorders includes heart failure (20.5%), stroke (20.1%), and asthma/chronic obstructive pulmonary disease (20.2%).

CONCLUSIONS

This high-dose influenza vaccine trial uniquely offers a paradigm for future studies of clinical and programmatic interventions within the framework of efforts designed to test the impact of changes in usual treatment practices adopted by health care systems.

New Evidence on the Green House Model of Nursing Home Care: Synthesis of Findings and Implications for Policy, Practice, and Research

OBJECTIVE

To synthesize new findings from the THRIVE Research Collaborative (The Research Initiative Valuing Eldercare) related to the Green House (GH) model of nursing home care and broadly consider their implications.

DATA SOURCES

Interviews and observations conducted in GH and comparison homes, Minimum Data Set (MDS) assessments, Medicare data, and Online Survey, Certification and Reporting data.

STUDY DESIGN

Critical integration and interpretation of findings based on primary data collected 2011-2014 in 28 GH homes (from 16 organizations), and 15 comparison nursing home units (from 8 organizations); and secondary data derived from 2005 to 2010 for 72 GH homes (from 15 organizations) and 223 comparison homes.

PRINCIPAL FINDINGS

Implementation of the GH model is inconsistent, sometimes differing from design. Among residents of GH homes, adoption lowers hospital readmissions, three MDS measures of poor quality, and Part A/hospice Medicare expenditures. Some evidence suggests the model is associated with lower direct care staff turnover.

CONCLUSIONS

Recommendations relate to assessing fidelity, monitoring quality, capitalizing opportunities to improve care, incorporating evidence-based practices, including primary care providers, supporting high-performance workforce practices, aligning Medicare financial incentives, promoting equity, informing broad culture change, and conducting future research.

Nursing home control of physician resources

OBJECTIVE

Physician services are increasingly recognized as important contributors to quality care provision in nursing homes (NH)s, but knowledge of ways in which NHs manage/control physician resources is lacking.

DATA

Primary data from surveys of NH administrators and directors of nursing from a nationally representative sample of 1938 freestanding United States NHs in 2009-2010 matched to Online Survey Certification and Reporting, aggregated NH Minimum Data Set assessments, Medicare claims, and county information from the Area Resource File.

METHODS

The concept of NH Control of Physician Resources (NHCOPR) was measured using NH administrators' reports of management implementation of rules, policies, and procedures aimed at coordinating work activities. The NHCOPR scale was based on measures of formal relationships, physician oversight and credentialing. Scale values ranged from weakest (0) to tightest (3) control. Several hypotheses of expected associations between NHCOPR and other measures of NH and market characteristics were tested.

RESULTS

The full NHCOPR score averaged 1.58 (standard deviation = 0.77) on the 0-3 scale. Nearly 30% of NHs had weak control (NHCOPR ≤1), 47.5% had average control (NHCOPR between 1 and 2), and the remaining 24.8% had tight control (NHCOPR >2). NHCOPR exhibited good face- and predictive-validity as exhibited by positive associations with more beds, more Medicare services, cross coverage, and number of physicians in the market.

CONCLUSIONS

The NHCOPR scale capturing NH's formal structure of control of physician resources can be useful in studying the impact of NH's physician resources on residents' outcomes with potential for targeted interventions by education and promotion of NH administration regarding physician staff.

Reducing hospital readmission rates: current strategies and future directions

New financial penalties for institutions with high readmission rates have intensified efforts to reduce rehospitalization. Several interventions that involve multiple components (e.g., patient needs assessment, medication reconciliation, patient education, arranging timely outpatient appointments, and providing telephone follow-up) have successfully reduced readmission rates for patients discharged to home. The effect of interventions on readmission rates is related to the number of components implemented; single-component interventions are unlikely to reduce readmissions significantly. For patients discharged to postacute care facilities, multicomponent interventions have reduced readmissions through enhanced communication, medication safety, advanced care planning, and enhanced training to manage medical conditions that commonly precipitate readmission. To help hospitals direct resources and services to patients with greater likelihood of readmission, risk-stratification methods are available. Future work should better define the roles of home-based services, information technology, mental health care, caregiver support, community partnerships, and new transitional care personnel.

An international survey of nursing homes

This article reports the results of an exploratory survey of nursing home care in 30 countries. Most countries used either a social or nursing home model, with a physician model being less common. Resident Assessment Instruments were used in only 35% of countries. Physician visits to the nursing home occurred in 37%. All but 2 countries used advanced practice nurses. Medication use was high, with 82% of countries reporting residents taking 6 or more medicines a day.
