Whether to transfer? Factors associated with hospitalization and outcome of elderly long-term care patients with pneumonia

Antibiotic use for respiratory tract infections among older adults living in long-term care facilities: a systematic review and meta-analysis

BACKGROUND

Antibiotics are commonly prescribed for respiratory tract infections (RTIs) among older adults in long-term care facilities (LTCFs), and this contributes to the emergence of antimicrobial resistance. The objective of this study was to determine the antibiotic prescribing rate for RTIs among LTCF residents, and to analyse the antibiotic consumption patterns with the AwaRe monitoring tool, developed by the World Health Organization.

METHODS

MEDLINE, EMBASE and CINAHL were searched from inception to March 2022. Original articles reporting antibiotic use for RTIs in LTCFs were included in this review. Study quality was assessed using the Joanna Briggs Institute's Critical Appraisal Checklist for Prevalence Data. A random-effects meta-analysis was employed to calculate the pooled estimates. Subgroup analysis was conducted by type of RTI, country, and study start year.

RESULTS

In total, 47 articles consisting of 50 studies were included. The antibiotic prescribing rate ranged from 21.5% to 100% (pooled estimate 69.8%, 95% confidence interval 55.2-82.6%). The antibiotic prescribing rate for lower respiratory tract infections (LRTIs) was higher than the rates for viral and general RTIs. Compared with Italy, France and the USA, the Netherlands had lower antibiotic use for LRTIs. A proportion of viral RTIs were treated with antibiotics, and all the antibiotics were from the Watch group. Use of antibiotics in the Access group was higher in the Netherlands, Norway, Switzerland and Slovenia compared with the USA and Australia.

CONCLUSION

The antibiotic prescribing rate for RTIs in LTCFs was high, and AWaRe antibiotic use patterns varied by type of RTI and country. Improving antibiotic use may require coordination efforts.

Facility Characteristics Associated With Intensity of Care of Nursing Homes and Hospital Referral Regions

OBJECTIVES

Intensity of care, such as hospital transfers and tube feeding of residents with advanced dementia varies by nursing home (NH) within and across regions. Little work has been done to understand how these 2 levels of influence relate. This study's objectives are to identify facility factors associated with NHs providing high-intensity care to residents with advanced dementia and determine whether these factors differ within and across hospital referral regions (HRRs).

DESIGN

Cross-sectional analysis.

SETTING AND PARTICIPANTS

1449 NHs.

METHODS

Nationwide 2016-2017 Minimum Data Set was used to categorize NHs and HRRs into 4 levels of care intensity based on rates of hospital transfers and tube feeding among residents with advanced dementia: low-intensity NH in a low-intensity HRR, high-intensity NH in a low-intensity HRR, low-intensity NH in a high-intensity HRR, and a high-intensity NH in a high-intensity HRR.

RESULTS

In high-intensity HRRs, high-vs low-intensity NHs were more likely to be urban, lack a dementia unit, have a nurse practitioner or physician (NP or PA) on staff, and have a higher proportion of residents who were male, aged <65 years, Black, had pressure ulcers, and shorter hospice stays. In low-intensity HRRs, higher proportion of Black residents was the only characteristic associated with being a high-intensity NH.

CONCLUSIONS AND IMPLICATIONS

These findings suggest that within high-intensity HRRs, there are potentially modifiable factors that could be targeted to reduce burdensome care in advanced dementia, including having a dementia unit, palliative care training for NPs and PAs, and increased use of hospice care.

The Trial to Reduce Antimicrobial Use in Nursing Home Residents With Alzheimer Disease and Other Dementias (TRAIN-AD): A Cluster Randomized Clinical Trial

IMPORTANCE

Antimicrobials are extensively prescribed to nursing home residents with advanced dementia, often without evidence of infection or consideration of the goals of care.

OBJECTIVE

To test the effectiveness of a multicomponent intervention to improve the management of suspected urinary tract infections (UTIs) and lower respiratory infections (LRIs) for nursing home residents with advanced dementia.

DESIGN, SETTING, AND PARTICIPANTS

A cluster randomized clinical trial of 28 Boston-area nursing homes (14 per arm) and 426 residents with advanced dementia (intervention arm, 199 residents; control arm, 227 residents) was conducted from August 1, 2017, to April 30, 2020.

INTERVENTIONS

The intervention content integrated best practices from infectious diseases and palliative care for management of suspected UTIs and LRIs in residents with advanced dementia. Components targeting nursing home practitioners (physicians, physician assistants, nurse practitioners, and nurses) included an in-person seminar, an online course, management algorithms (posters, pocket cards), communication tips (pocket cards), and feedback reports on prescribing of antimicrobials. The residents' health care proxies received a booklet about infections in advanced dementia. Nursing homes in the control arm continued routine care.

MAIN OUTCOMES AND MEASURES

The primary outcome was antimicrobial treatment courses for suspected UTIs or LRIs per person-year. Outcomes were measured for as many as 12 months. Secondary outcomes were antimicrobial courses for suspected UTIs and LRIs when minimal criteria for treatment were absent per person-year and burdensome procedures used to manage these episodes (bladder catherization, chest radiography, venous blood sampling, or hospital transfer) per person-year.

RESULTS

The intervention arm had 199 residents (mean [SD] age, 87.7 [8.0] years; 163 [81.9%] women; 36 [18.1%] men), of which 163 (81.9%) were White and 27 (13.6%) were Black. The control arm had 227 residents (mean [SD] age, 85.3 [8.6] years; 190 [83.7%] women; 37 [16.3%] men), of which 200 (88.1%) were White and 22 (9.7%) were Black. There was a 33% (nonsignificant) reduction in antimicrobial treatment courses for suspected UTIs or LRIs per person-year in the intervention vs control arm (adjusted marginal rate difference, -0.27 [95% CI, -0.71 to 0.17]). This reduction was primarily attributable to reduced antimicrobial use for LRIs. The following secondary outcomes did not differ significantly between arms: antimicrobials initiated when minimal criteria were absent, bladder catheterizations, venous blood sampling, and hospital transfers. Chest radiography use was significantly lower in the intervention arm (adjusted marginal rate difference, -0.56 [95% CI, -1.10 to -0.03]). In-person or online training was completed by 88% of the targeted nursing home practitioners.

CONCLUSIONS AND RELEVANCE

This cluster randomized clinical trial found that despite high adherence to the training, a multicomponent intervention promoting goal-directed care for suspected UTIs and LRIs did not significantly reduce antimicrobial use among nursing home residents with advanced dementia.

Elderly bedridden patients with dementia use over one quarter of resources in internal medicine wards in an Israeli hospital

Background

Elderly bedridden patients with dementia (EBRPD) are a growing segment of the population. We aimed to describe acute care hospitalization of EBRPD in internal medicine wards: the prevalence of EBRPD, their impact on hospital resources and hospital ecology, one-year survival, and one-year readmission-free survival.

Methods

The study setting was the internal medicine division of one tertiary care hospital in Israel. We conducted a point-prevalence survey to measure the prevalence of EBRPD and the prevalence of multidrug-resistant organism (MDRO) carriage. We also conducted a retrospective chart review of EBRPD who were hospitalized in the internal medicine division in order to assess resource use, survival, and readmission.

Results

In the point prevalence surveys (N = 1667 patients), EBRPD comprised 24.3% of patients and 59.0% of mechanically ventilated patients. EBRPD were twice as likely to be colonized or infected by MDROs as other patients (39.3% vs. 18%, p < 0.001); thus, 41% of MDRO carriers during the survey days were EBRPD. In the retrospective study (N = 517 EBRPD), 80% of EBRPD received antibiotics; on average, they received an antibiotic on 87.7% of their hospital days. One-year survival was 35.6% and one-year readmission-free survival was 16.4%.

Conclusions

Acute care hospitalization of EBRPD accounted for a high proportion of bed occupancy and ventilator use in internal medicine wards. EBRPD significantly increase the potential for MDRO transmission. Policymakers should seek alternatives to acute care hospitalization for EBRPD.

Hospital Transfer Rates Among US Nursing Home Residents With Advanced Illness Before and After Initiatives to Reduce Hospitalizations

IMPORTANCE

Hospital transfers among nursing home residents in the United States who have been diagnosed with advanced illnesses and have limited life expectancy are often burdensome, costly, and of little clinical benefit. National initiatives, introduced since 2012, have focused on reducing such hospitalizations, but little is known about the consequences of these initiatives in this population.

OBJECTIVE

To investigate the change in hospital transfer rates among nursing home residents with advanced illnesses, such as dementia, congestive heart failure (CHF), and chronic obstructive pulmonary disease (COPD), from 2011 to 2017-before and after the introduction of national initiatives to reduce hospitalizations.

DESIGN, SETTING, AND PARTICIPANTS

In this cross-sectional study, nationwide Minimum Data Set (MDS) assessments from January 1, 2011, to December 31, 2016 (with the follow-up for transfer rates until December 31, 2017), were used to identify annual inception cohorts of long-stay (>100 days) nursing home residents who had recently progressed to the advanced stages of dementia, CHF, or COPD. The data were analyzed from October 24, 2018, to October 3, 2019.

MAIN OUTCOMES AND MEASURES

The number of hospital transfers (hospitalizations, observation stays, and emergency department visits) per person-year alive was calculated from the MDS assessment from the date when residents first met the criteria for advanced illness up to 12 months afterward using Medicare claims from 2011 to 2017. Transfer rates for all causes, potentially avoidable conditions (sepsis, pneumonia, dehydration, urinary tract infections, CHF, and COPD), and serious bone fractures (pelvis, hip, wrist, ankle, and long bones of arms or legs) were investigated. Hospice enrollment and mortality were also ascertained.

RESULTS

The proportions of residents in the 2011 and 2016 cohorts who underwent any hospital transfer were 56.1% and 45.4% of those with advanced dementia, 77.6% and 69.5% of those with CHF, and 76.2% and 67.2% of those with COPD. The mean (SD) number of transfers per person-year alive for potentially avoidable conditions was higher in the 2011 cohort vs 2016 cohort: advanced dementia, 2.4 (14.0) vs 1.6 (11.2) (adjusted risk ratio [aRR], 0.73; 95% CI, 0.65-0.81); CHF, 8.5 (32.0) vs 6.7 (26.8) (aRR, 0.72; 95% CI, 0.65-0.81); and COPD, 7.8 (30.9) vs 5.5 (24.8) (aRR, 0.64; 95% CI, 0.57-0.72). Transfers for bone fractures remained unchanged, and mortality did not increase. Hospice enrollment was low across all illness groups and years (range, 23%-30%).

CONCLUSIONS AND RELEVANCE

The findings of this study suggest that concurrent with new initiatives aimed at reducing hospitalizations, hospital transfers declined between 2011 and 2017 among nursing home residents with advanced illnesses without increased mortality rates. Opportunities remain to further reduce unnecessary hospital transfers in this population and improve goal-directed care for those residents who opt to forgo hospitalization.

Nursing Home-Associated Pneumonia, Part II: Etiology and Treatment

This is the second of 2 parts of a narrative review of nursing home-associated pneumonia (NHAP) that deals with etiology and treatment in the nursing home. In the 1980s and 1990s, the etiology of NHAP was considered to be similar to community-acquired pneumonia (CAP). This belief was reflected in CAP guidelines until 2005 when the designation healthcare-associated pneumonia or HCAP was introduced and nursing home residents were included in the HCAP category. Patients in the HCAP group were thought to be at high risk for pneumonia because of multidrug resistant organisms and required empiric broad-spectrum antibiotic therapy much like people with hospital-acquired infection. Subsequent studies of the etiology of NHAP using sophisticated diagnostic testing found limited evidence of resistant organisms such as methicillin-resistant Staphylococcus aureus or resistant gram-negative organisms or atypical organisms. In terms of management of NHAP in the nursing home there are several considerations that are discussed: hospitalization decision, initial oral or parenteral therapy, timing of switch to an oral regimen if parenteral therapy is initially prescribed, duration of therapy with an emphasis on shorter courses, and follow-up during therapy including the use of the "antibiotic time out" protocol. The oral and parenteral antibiotic regimens recommended for treatment of NHAP in this report are based on limited information because there are no randomized controlled trials to define the optimum regimen. In conclusion, most residents with pneumonia can be treated successfully in the nursing home. However, there is an urgent need for a specific NHAP diagnosis and treatment guideline that will give providers guidance in the management of this infection in the nursing home.

Impact of mobile radiography services in nursing homes on the utilisation of diagnostic imaging procedures

Background

In the last decade, mobile radiography services have been introduced in nursing homes in several countries. Earlier research found an underutilisation of diagnostic imaging among nursing home residents. However, the effects of introducing mobile radiography services on the use of diagnostic imaging are unknown. The purpose of this study was to determine the utilisation of diagnostic imaging among nursing home residents and if there are any differences between hospitals with and without a mobile radiography service.

Methods

Data for 2015 were collected from the radiological information systems of 11 hospitals. The data included information on the anatomical region/organ/organ system, modality, and information on where the examination took place. Using nursing home beds as a proxy for nursing home residents’ differences in the use of diagnostic imaging in areas with hospitals with and without mobile radiography services were analysed. The chi-squared test was used to compare the areas.

Results

From 11,066 examinations of nursing home residents, 87% were plain radiographs, 8% were CT scans, and 4% were ultrasound examinations. In areas with mobile radiography services, there was a significantly higher proportion of diagnostic imaging used per nursing home bed, 50% per bed compared to 36% per bed in areas without; p = < 0.001. Furthermore, in areas with mobile radiography services, there was a significantly lower proportion of CT and ultrasound used per nursing home bed, 2.5 and 1.4% respectively per bed compared to 4.7 and 2.2% respectively per bed in areas without; p = < 0.001.

Conclusions

This study demonstrate a lower use of radiology by nursing home residents compared to the general population, and indicates that mobile radiography services increase the level closer to the user rate in the general population. The proportions of plain radiographs are significantly higher in areas with a mobile radiography service, while the proportion of more advanced imaging techniques such as CT and ultrasound are lower. The higher use of diagnostic imaging is most likely appropriate because of higher morbidity and lower use of diagnostic imaging among nursing home residents, compared to the general population. Further research is necessary on how to improve diagnostic imaging services for nursing home residents.

Cost analysis of mobile radiography services for nursing home residents in Southeast Norway

RATIONALE, AIMS, AND OBJECTIVE

Telemedicine applications, such as a mobile radiography service, provide a new way of organizing healthcare services. In order to provide safe and personalised care for nursing home residents during X-ray examinations, mobile radiography services have been implemented. The objective of this study was to analyse the costs of X-ray examinations and treatments for nursing home residents when comparing hospital-based imaging with a combination of hospital-based imaging and a mobile radiography service in Southeast Norway.

METHODS

A decision model was developed using the software TreeAge Pro. The model included two alternatives: the mobile radiography service in combination with hospital-based imaging and hospital-based imaging alone. The treatment needed based on the examination results could be given either in the nursing home or at the hospital. Probabilities and costs in the model were derived from previous research, various reports, and hospital data from the Southeast region of Norway. Monte Carlo simulations of 1000 residents were run through the model, and statistical analyses were applied.

RESULTS

The analysis showed a mean cost of €2790 per resident for the hospital-based service alone. For mobile and hospital-based services combined, the mean cost was €1946 per resident, including examinations and the immediate treatment given. This difference in costs was significant (p < 0.001).

CONCLUSION

A mobile radiography service in nursing homes provides a safe, high quality health care service. The result of this study showed there was a 30% cost-reduction by implementing the mobile radiography service.

Reducing emergency presentations from long-term care: A before-and-after study of a multidisciplinary team intervention

INTRODUCTION

The complexity of care required by many older people living in long-term care (LTC) facilities poses challenges that can lead to potentially avoidable referrals to a hospital emergency department (ED). The Aged Residential Care Intervention Project (ARCHIP) ran an implementation study to evaluate a multidisciplinary team (MDT) intervention supporting LTC facility staff to decrease potentially avoidable ED presentations by residents.

METHODS

ARCHIP (conducted in 21 facilities [1,296 beds] with previously noted high ED referral rates) comprised clinical coaching for LTC facility staff by a gerontology nurse specialist (GNS) and an MDT (facility senior nurse, resident's general practitioner, GNS, geriatrician, pharmacist) review of selected high-risk residents' care-plans. A before-after repeated measures analysis was conducted for 9 months before and 9 months after intervention commencement (a 29-month period because of staggered facility enrolment). Modelling was adjusted for time trend, seasonality, facility size, and cluster effect.

RESULTS

ED admission rate ratio post- versus pre-intervention was 0.75 (95% C.I. 0.63, 0.89, p-value = 0.0008), a 25% reduction in ED presentations post-intervention. A sensitivity model used a shorter, staggered time period centred on intervention start (9 months pre-intervention and 9 months post-intervention) for each facility, and a four-level categorical intervention variable testing intervention effect over time. The sensitivity test showed a 24% reduction in ED presentations in months 1-3 post-intervention (p-value = 0.07), a 34% reduction in months 4-6 (p-value = 0.01), and a 32% reduction in ED presentations in months 7-9 (p-value = 0.03). However, when the higher ED referral rates for 3 months immediately pre-intervention were modelled, the impact of the intervention on ED presentation rates reverted almost to previous levels.

KEY CONCLUSIONS

A GNS-led MDT outreach intervention, targeted at selected conditions, decreases avoidable ED admissions of high-risk residents from selected facilities.

Managers' experience of success criteria and barriers to implementing mobile radiography services in nursing homes in Norway: a qualitative study

Background

In order to meet the future challenges posed by ageing populations, new technology, telemedicine and a more personalized healthcare system are needed. Earlier research has shown mobile radiography services to be highly beneficial for nursing home residents in addition to being cost-effective. Despite the benefits, mobile radiography services are uncommon in Europe and Norway. The purpose of this study was to explore success criteria and barriers in the process of implementing mobile radiography services, from the point of view of the hospital and municipal managers.

Methods

Eleven semi-structured interviews were conducted with managers from five hospitals and six municipalities in Norway where mobile radiography services had been implemented. Core issues in the interview guide were barriers and facilitators in the different phases of implementation. The framework method for thematic analysis was used for analysing the data inductively in a research team.

Results

Five main categories were developed through the success criteria and barriers experienced by the participants: national health policy, regional and municipal policy and conditions, inter-organizational implementation projects, experienced outcome, and professional skills and personal characteristics. The categories were allocated into three higher-order classifications: macro, meso and micro levels. The main barriers experienced by the managers were financial, procedural and structural. In particular, the reimbursement system, lack of management across healthcare levels and the lack of compatible information systems acted as barriers. The main facilitators were external funding, enthusiastic individuals in the organizations and good collaboration between hospitals and municipalities.

Conclusions

The managers experienced financial, structural and procedural barriers. The main success criteria in the process were external funding, and the support and engagement from the individuals in the organizations. This commitment was mainly facilitated by the intuitive appeal of mobile radiography. Changes in healthcare management and in the financial system might facilitate services across healthcare levels. In addition, compatible information systems across healthcare levels are needed in order to facilitate the use of new technology and mobile services.

Mobile radiography services in nursing homes: a systematic review of residents' and societal outcomes

Background

Demographic changes are leading to an ageing population in Europe, and predict an increase in the number of nursing home residents over the next 30 years. Nursing home residents need specialised healthcare services such as radiology due to both chronic and acute illnesses. Mobile radiography, x-ray examinations performed in the nursing homes, may be a good way of providing services to this population. The aim of this systematic review was to identify the outcomes of mobile radiography services for nursing home residents and society.

Methods

A systematic review based on searches in the Medline, Cochrane, PubMed, Embase and Svemed + databases was performed. Titles and abstracts were screened according to a predefined set of inclusion criteria: empirical studies in the geriatric population, and reports of mobile radiography services in a clinical setting. All publications were quality appraised using MMAT or CASP appraisal tools. Data were extracted using a summary table and results were narratively synthesised.

Results

Ten publications were included. Three overarching outcomes were identified: 1) reduced number of hospitalisations and outpatient examinations or treatments, 2) reduced number of transfers between nursing homes and hospitals and 3) increased access to x-ray examinations. These outcomes were interlinked with the more specific outcomes for residents and society reported in the literature. For residents there was a reduction in burdensome transfers and waiting time and adequate treatment and care increased. For society, released resources could be used more efficiently, and overall costs were reduced substantially.

Conclusions

This review indicates that mobile radiography services for nursing home residents in the western world are of comparable quality to hospital-based examinations and have clear potential benefits. Mobile radiography reduced transfers to and from hospital, increased the number of examinations carried out and facilitated timely diagnosis and access to treatments. Further research is needed to formally evaluate potential improvements in care quality and cost-effectiveness.

Derivation and Confirmation of Scales Measuring Medical Directors’ Attitudes About the Hospitalization of Nursing Home Residents

Objectives: To derive and confirm scales measuring medical director’s attitudes about hospitalization of nursing home residents.

Method: The authors surveyed nursing facility medical directors about the necessity of hospitalizing residents for eight clinical conditions and compared the ratings to those obtained from an expert panel to derive a relative hospitalization score. They also asked about factors that might influence hospitalization decisions. They performed a factor analysis to derive scales that measure attitudinal determinants of hospitalization and used the relative hospitalization score to confirm the scales.

Results: The survey had a 79% response rate. The relative hospitalization score demonstrated that medical directors were slightly less likely to recommend hospitalization than expert panel physicians. Factor analyses yielded 10 scales focusing on nursing home functioning, economics, resident specific considerations, and physician attitudes. Eight of the 10 scales had significant bivariable associations with the relative hospitalization score, and 6 had significant multivariable associations.

Discussion: Medical directors identify multiple determinants of hospitalization for nursing facility residents across several domains. Hospitalization decisions for nursing facility residents are complex and involve clinical and nonclinical factors.

The 'Big Five'. Hypothesis generation: a multidisciplinary intervention package reduces disease-specific hospitalisations from long-term care: a post hoc analysis of the ARCHUS cluster-randomised controlled trial

INTRODUCTION

long-term care (LTC) residents have higher hospitalisation rates than non-LTC residents. Rapid decline may follow hospitalisations, hence the importance of preventing unnecessary hospitalisations. Literature describes diagnosis-specific interventions (for cardiac failure, ischaemic heart disease, chronic obstructive pulmonary disease, stroke, pneumonia-termed 'big five' diagnoses), impacting on hospitalisations of older community-dwellers, but few RCTs show reductions in acute admissions from LTC.

METHODS

LTC facilities with higher than expected hospitalisations were recruited for a cluster-randomised controlled trial (RCT) of facility-based complex, non-disease-specific, 9-month intervention comprising gerontology nurse specialist (GNS)-led staff education, facility benchmarking, GNS resident review and multidisciplinary discussion of residents selected using standard criteria. In this post hoc exploratory analysis, the outcome was acute hospitalisations for 'big five' diagnoses. Re-randomisation analyses were used for end points during months 1-14. For end points during months 4-14, proportional hazards models are adjusted for within-facility clustering.

RESULTS

we recruited 36 facilities with 1,998 residents (1,408 female; mean age 82.9 years); 1,924 were alive at 3 months. The intervention did not impact overall rates of acute hospitalisations or mortality (previously published), but resulted in fewer 'big five' admissions (RR = 0.73, 95% CI = 0.54-0.99; P = 0.043) with no significant difference in the rate of other acute admissions. When considering events occurring after 3 months (only), the intervention group were 34.7% (HR = 0.65; 95% CI = 0.49-0.88; P = 0.005) less likely to have a 'big five' acute admission than controls, with no differences in likelihood of acute admissions for other diagnoses (P = 0.96).

CONCLUSIONS

this generic intervention may reduce admissions for common conditions which the literature shows are impacted by disease-specific admission reduction strategies.

The Impact of Medicaid Payer Status on Hospitalizations in Nursing Homes

OBJECTIVES

To examine the association between payer status (Medicaid vs. private-pay) and the risk of hospitalizations among long-term stay nursing home (NH) residents who reside in the same facility.

DATA AND STUDY POPULATION

The 2007-2010 National Medicare Claims and the Minimum Data Set were linked. We identified newly admitted NH residents who became long-stayers and then followed them for 180 days.

ANALYSES

Three dichotomous outcomes-all-cause, discretionary, and nondiscretionary hospitalizations during the follow-up period-were defined. Linear probability model with facility fixed-effects and robust SEs were used to examine the within-facility difference in hospitalizations between Medicaid and private-pay residents. A set of sensitivity analyses were performed to examine the robustness of the findings.

RESULTS

The prevalence of all-cause hospitalization during a 180-day follow-up period was 23.3% among Medicaid residents compared with 21.6% among private-pay residents. After accounting for individual characteristics and facility effects, the probability of any all-cause hospitalization was 1.8-percentage point (P<0.01) higher for Medicaid residents than for private-pay residents within the same facility. We also found that Medicaid residents were more likely to be hospitalized for discretionary conditions (5% increase in the likelihood of discretionary hospitalizations), but not for nondiscretionary conditions. The findings from the sensitivity analyses were consistent with the main analyses.

CONCLUSIONS

We observed a higher hospitalization rate among Medicaid NH residents than private-pay residents. The difference is in part driven by the financial incentives NHs have to hospitalize Medicaid residents.

The cost-effectiveness of the decision to hospitalize nursing home residents with advanced dementia

CONTEXT

Nursing home (NH) residents with advanced dementia commonly experience burdensome and costly hospitalizations that may not extend survival or improve quality of life. Cost-effectiveness analyses of decisions to hospitalize these residents have not been reported.

OBJECTIVES

To estimate the cost-effectiveness of 1) not having a do-not-hospitalize (DNH) order and 2) hospitalization for suspected pneumonia in NH residents with advanced dementia.

METHODS

NH residents from 22 NHs in the Boston area were followed in the Choices, Attitudes, and Strategies for Care of Advanced Dementia at the End-of-Life study conducted between February 2003 and February 2009. We conducted cost-effectiveness analyses of aggressive treatment strategies for advanced dementia residents living in NHs when they suffer from acute illness. Primary outcome measures included quality-adjusted life days (QALD) and quality-adjusted life years, Medicare expenditures, and incremental net benefits (INBs) over 15 months.

RESULTS

Compared with a less aggressive strategy of avoiding hospital transfer (i.e., having DNH orders), the strategy of hospitalization was associated with an incremental increase in Medicare expenditures of $5972 and an incremental gain in quality-adjusted survival of 3.7 QALD. Hospitalization for pneumonia was associated with an incremental increase in Medicare expenditures of $3697 and an incremental reduction in quality-adjusted survival of 9.7 QALD. At a willingness-to-pay level of $100,000/quality-adjusted life years, the INBs of the more aggressive treatment strategies were negative and, therefore, not cost effective (INB for not having a DNH order, -$4958 and INB for hospital transfer for pneumonia, -$6355).

CONCLUSION

Treatment strategies favoring hospitalization for NH residents with advanced dementia are not cost effective.

Shipping out instead of shaping up: rehospitalization from nursing homes as an unintended effect of public reporting

Public reporting of health care quality has become a popular tool for incenting quality improvement. A fundamental question about public reporting is whether it causes providers to select healthier patients for treatment. In the nursing home post-acute setting, where patients must achieve a minimum length of stay to be included in quality measures, selection may take the form of discharge from the nursing home using rehospitalization, a particularly costly and undesirable outcome. We study the population of post-acute patients of skilled nursing facilities nationwide during 1999-2005 to assess whether selective rehospitalization occurred when public reporting was instituted in 2002, using multiple quasi-experimental designs to identify effects. We find that after public reporting was implemented, rehospitalizations before the length-of-stay cutoff increased. We conclude that nursing homes rehospitalize higher-risk post-acute patients to improve scores, providing evidence for selection behavior on the part of nursing home providers in the presence of public reporting.

Multidrug resistant bacteria isolated from cockroaches in long-term care facilities and nursing homes

Residents in long-term care facilities and nursing homes have a relative higher risk for infections. The nocturnal and filthy habits of cockroaches may be ideal disseminators of pathogenic microorganisms in these institutions. This study was designed to determine the infestation and vector potential of cockroaches under this institutional environment. Cockroaches were collected from 69 long-term care facilities and nursing homes in Kaohsiung City. Risk factors related to cockroach infestation were determined by questionnaire survey. In addition, bacteria were isolated and identified from the alimentary tract and external surface of these insects. Antibiotic resistances of these microorganisms were then determined. Cockroach infestation was found in 45 (65.2%) institutions and 558 cockroaches (119 Periplaneta americana and 439 Blattella germanica) were collected. A significant association was found between cockroach infestation and indoor environmental sanitation. From 250 adult cockroaches, 38 species of gram-negative bacteria, 20 species of glucose non-fermenter bacilli and 6 species of gram-positive bacteria were isolated. Moreover, antibiotic resistances were found among the bacteria isolated. These findings indicate that cockroaches have the potential in transmitting pathogenic bacteria with multidrug resistances in long-term care facilities and nursing homes.

Stakeholder perspectives on transitions of nursing home residents to hospital emergency departments and back in two Canadian provinces

Major gaps exist in our understanding of transitions in care for older persons living in nursing homes. The purpose of the study was to identify key elements, from multiple stakeholder perspectives, that influence the success of transitions experienced by nursing home residents when they required transfer to a hospital emergency department. This interpretive descriptive study was conducted in two cities in the Canadian provinces of British Columbia and Alberta. Data were collected from 71 participants via focus groups and individual interviews with nursing home residents, family members, and professional healthcare providers working in nursing homes, emergency departments, and emergency medical services. Transcripts were analyzed using constant comparison. The elements contributing to the success of transitions reflected a patient- and family-centered approach to care. Transitions were influenced by the complex interplay of multiple elements that included: knowing the resident; critical geriatric knowledge and skilled assessment; positive relationships; effective communication; and timeliness. When one or more of the elements was absent or compromised, the success of the transition was also compromised. There was consistency about the importance of all the identified elements across all stakeholder groups whether they are residents, family members, or health professionals in nursing homes, emergency departments or emergency medical services. Aspects of many of these elements are modifiable and suggest viable targets for interventions aimed at improving the success of transitions for this vulnerable population.

Advanced dementia: state of the art and priorities for the next decade

Dementia is a leading cause of death in the United States. This article outlines the current understanding of advanced dementia and identifies research priorities for the next decade. Research over the past 25 years has largely focused on describing the experience of patients with advanced dementia. This work has delineated abundant opportunities for improvement, including greater recognition of advanced dementia as a terminal illness, better treatment of distressing symptoms, increased access to hospice and palliative care services, and less use of costly and aggressive treatments that may be of limited clinical benefit. Addressing those opportunities must be the overarching objective for the field in the coming decade. Priority areas include designing and testing interventions that promote high-quality, goal-directed care; health policy research to identify strategies that incentivize cost-effective and evidence-based care; implementation studies of promising interventions and policies; and further development of disease-specific outcome measures. There is great need and opportunity to improve outcomes, contain expenditures, reduce disparities, and better coordinate care for the millions of persons in the United States who have advanced dementia.

Advanced dementia: state of the art and priorities for the next decade

Dementia is a leading cause of death in the United States. This article outlines the current understanding of advanced dementia and identifies research priorities for the next decade. Research over the past 25 years has largely focused on describing the experience of patients with advanced dementia. This work has delineated abundant opportunities for improvement, including greater recognition of advanced dementia as a terminal illness, better treatment of distressing symptoms, increased access to hospice and palliative care services, and less use of costly and aggressive treatments that may be of limited clinical benefit. Addressing those opportunities must be the overarching objective for the field in the coming decade. Priority areas include designing and testing interventions that promote high-quality, goal-directed care; health policy research to identify strategies that incentivize cost-effective and evidence-based care; implementation studies of promising interventions and policies; and further development of disease-specific outcome measures. There is great need and opportunity to improve outcomes, contain expenditures, reduce disparities, and better coordinate care for the millions of persons in the United States who have advanced dementia.

Pneumonia in the long-term resident

Pneumonia in the long-term resident is common. It is associated with high morbidity and mortality. However, diagnosis and management of pneumonia in long-term care residents is challenging. This article provides an overview of the epidemiology, pathophysiology, diagnostic challenges, and management recommendations for pneumonia in this setting.

Management of pneumonia in the nursing home

Pneumonia is a major cause of morbidity and mortality among nursing home residents. The approach to managing these patients has lacked uniformity because of the paucity of clinical trials, complexity of underlying comorbid diseases, and heterogeneity of administrative structures. The decision to hospitalize nursing home patients with pneumonia varies among institutions depending on staffing level, availability of diagnostic testing, and laboratory support. In the absence of comparative studies, choice of empirical antibiotic therapy continues to be based on expert opinion. Validated prognostic scoring models are needed for risk stratification. Pneumococcal and influenza vaccination are the primary prevention measures. As of January 2010, Medicare no longer pays for consultation codes; thus, practitioners must instead use existing evaluation and management service codes when providing these services.

Nursing home-acquired pneumonia: a review of risk factors and therapeutic approaches

OBJECTIVE

To review the risk factors, etiologic profile, treatment approaches, and guidelines for the management of nursing home-acquired pneumonia (NHAP).

RESEARCH DESIGN AND METHODS

A search of the current literature was conducted using the MEDLINE and Embase databases. This search, limited to studies performed in humans and published in English between January 1, 1990 and October 31, 2009, included the terms 'acquired pneumonia', 'associated pneumonia', 'nursing home', 'long-term care', 'institution', and 'healthcare'.

RESULTS

Older age, male gender, swallowing difficulty, and inability to take oral medications are all significant risk factors for pneumonia. Medications such as antipsychotics and anticholinergics, histamine receptor blockers and proton pump inhibitors have also been linked to higher risk of pneumonia. The etiology of NHAP overlaps with that of community-acquired pneumonia (CAP), with Streptococcus pneumoniae and Haemophilus influenzae as predominant pathogens in long-term care facilities. In patients who require hospitalization, Chlamydophila pneumoniae, Staphylococcus aureus, and influenza virus have also been identified. In contrast, the etiology of severe NHAP overlaps with that of hospital-acquired pneumonia (HAP), with S. aureus, including methicillin-resistant S. aureus (MRSA), Pseudomonas aeruginosa, and enteric Gram-negative bacilli as important causative pathogens. Therapy is dependent on disease severity and, on the treatment setting. Respiratory fluoroquinolones or β-lactams plus a macrolide are recommended in patients with NHAP. Patients hospitalized with severe NHAP may require triple combination therapy that covers both MRSA and P. aeruginosa. However, there is little evidence of the clinical superiority of one regimen over another, making it challenging to establish guidelines for the treatment of NHAP in the nursing home setting.

CONCLUSION

There is a pressing need for clinical trials of antibiotic therapy in nursing home patients that would help establish uniform guidelines to standardize therapy in the nursing home setting.

Physicians' attitudes toward guidelines for the treatment of hospitalized nursing home-acquired pneumonia

OBJECTIVES

To assess physician awareness, attitudes, and barriers toward the 2005 American Thoracic Society (ATS)/Infectious Diseases Society of America (IDSA) guidelines for the treatment of hospitalized nursing home-acquired pneumonia (NHAP).

METHODS

We conducted a cross-sectional survey of 522 health care providers. The survey assessed the practice setting characteristics, physicians' attitudes, and reported awareness of the 2005 ATS/IDSA guidelines. Factor analysis was conducted to identify scales of variables, and a reliability analysis was performed to verify the reliability of the identified scales.

RESULTS

Three hundred and ten completed the survey. Most responders (88%) reported familiarity with the practice guidelines in their field, but less than half were familiar with the ATS/IDSA NHAP guidelines. Although attitude scores regarding clinical practice guidelines did not differ significantly among various disciplines (P = .63), there were 2 characteristics that correlated with positive attitudes toward the 2005 ATS/IDSA guidelines in a multivariate analysis: being a pulmonary specialist (P ≤ .001) and time spent on CME activity per month (P = .03). The main barriers to the 2005 ATS/IDSA guidelines implementation were lack of awareness, concerns about practicality of using the recommended regimens, increased cost, lack of documented improved outcomes, and potential conflict with other guidelines.

CONCLUSION

The study indicates low levels of awareness with the 2005 ATS/IDSA guidelines for treatment of hospitalized NHAP. Targeted intervention efforts including outcome assessment and cost-effective analysis may be necessary to improve adherence with the proposed guidelines.

Low zinc status: a new risk factor for pneumonia in the elderly?

Low zinc status may be a risk factor for pneumonia in the elderly. This special article reviews the magnitude of the problem of pneumonia (its prevalence, morbidity, and mortality) in the elderly, pneumonia's etiology, and the dysregulation of the immune system associated with increasing age. In addition, recent evidence from the literature is presented demonstrating that low zinc status (commonly reported in the elderly) impairs immune function, decreases resistance to pathogens, and is associated with increased incidence and duration of pneumonia, increased use and duration of antimicrobial treatment, and increased overall mortality in the elderly. Inadequate stores of zinc might, therefore, be a risk factor for pneumonia in the elderly. Randomized, double-blind, controlled studies are needed to determine the efficacy of zinc supplementation as a potential low-cost intervention to reduce morbidity and mortality due to pneumonia in this vulnerable population.

Pneumonia in the elderly: a review of severity assessment, prognosis, mortality, prevention, and treatment

Pneumonia is an increasingly common disease in the elderly due to an aging population. This is a comprehensive literature review outlining the severity assessment, morbidity, mortality, prevention and treatment options. Several models have been postulated to predict severity assessment and prognosis in older patients. Mortality increases with age and functional status is also an independent predictor for short- and long-term mortality. The effectiveness of the pneumococcal vaccine is controversial, whereas the influenza vaccine is universally recommended. Treatment involves antibiotics with the type and method depending on the severity of the pneumonia. However, treatment of nursing home patients is challenging and there are no validated guidelines at present to determine when transfer to the hospital is necessary.

Treatment decisions regarding hospitalization and surgery for nursing home residents with advanced dementia: the CareAD Study

BACKGROUND

Dementia differs from other terminal illnesses both in its slow progression and the fact that patients and family members often do not perceive it as a cause of death. Furthermore, because decisional incapacity is almost universal in patients with advanced dementia, decisions must be made by surrogates. However, little is known about the factors that influence how surrogates make decisions for persons with late-stage dementia.

METHODS

The setting was the first wave of a study of patients with advanced dementia in three Maryland nursing homes (The Care of Nursing Home Residents with Advanced Dementia Study). Of 125 consented participants, 123 residents and their surrogates provided adequate information and agreed to interviews and medical record reviews. Bivariate analysis and logistic regression models were used to explore whether variables related to demographics, illness, communication and surrogate background were associated with surrogate decisions to not provide aggressive treatments (i.e. hospitalization or surgery).

RESULTS

Treatment decisions regarding aggressive medical care had been made by 81% of surrogates over the preceding 6 months. In bivariate analysis the following factors were significantly associated with not providing aggressive care: resident and surrogate of white race, older surrogate age, worse resident medical illness, worse surrogate perception of resident quality of life, presence of a 'do not hospitalize' order (DNH), and more contact with nurses. In the multivariate analysis, resident white race and presence of a DNH were significant predictors of surrogate decisions to not provide aggressive treatments. Treatment decisions were not associated with surrogate relationship or religiosity.

CONCLUSIONS

Treatment decisions for individuals with advanced dementia are mostly strongly associated with the patient's race and presence of DNH and less so with changeable features of illness or environment.

Healthcare-associated pneumonia: principles and emerging concepts on management

Healthcare-associated pneumonia (HCAP) is a relatively new entity that includes pneumonia occurring in healthcare settings other than acute-care hospitals. Many patients with HCAP are at greater risk for colonization and infection with multi-drug resistant (MDR) bacteria such as Pseudomonas aeruginosa, Gram-negative bacilli-producing extended-spectrum beta-lactamases and methicillin-resistant Staphylococcus aureus. Infections with these MDR pathogens require different empiric antibiotic therapy. To avoid initiation of inappropriate antibiotic therapy that may result in poorer patient outcomes, new principles for HCAP management were outlined in the 2005 American Thoracic Society and Infectious Diseases Society of America guidelines. These guidelines were suggested for patients assessed in acute-care hospitals and clinics, and may not be applicable for all patients with suspected HCAP in nursing homes and other long-term care settings. This review article addresses HCAP management strategies in both clinical settings.

Predictors of nursing home hospitalization: a review of the literature

Hospitalization of nursing home residents is costly and potentially exposes residents to iatrogenic disease and psychological harm. This article critically reviews the association between the decision to hospitalize and factors related to the residents' welfare and preferences, the providers' attitudes, and the financial implications of hospitalization. Regarding the resident's welfare, factors associated with hospitalization included sociodemographics, health characteristics, nurse staffing, the presence of ancillary services, and the use of hospices. Patient preferences (e.g., advance directives) and provider attitudes (e.g., overburdening of staff) were also associated with increased hospitalization. Finally, financial variables related to hospitalization included nursing home ownership status and state Medicaid policies, such as nursing home payment rates and bed-hold requirements. Most studies relied on potentially confounded research designs, which leave open the issue of selection bias. Nevertheless, the existing literature asserts that nursing home hospitalizations are frequent, often preventable, and related to facility practices and state Medicaid policies.

Reducing Hospitalizations From Long-Term Care Settings

Hospital spending represents approximately one third of total national health spending, and the majority of hospital spending is by public payers. Elderly individuals with long-term care needs are at particular risk for hospitalization. While some hospitalizations are unavoidable, many are not, and there may be benefits to reducing hospitalizations in terms of health and cost. This article reviews the evidence from 55 peer-reviewed articles on interventions that potentially reduce hospitalizations from formal long-term care settings. The interventions showing the strongest potential are those that increase skilled staffing, especially through physician assistants and nurse practitioners; improve the hospital-to-home transition; substitute home health care for selected hospital admissions; and align reimbursement policies such that providers do not have a financial incentive to hospitalize. Much of the evidence is weak and could benefit from improved research design and methodology.

Decisions About Transfer From Nursing Home to Emergency Department

PURPOSE

To describe how decisions occurred to transfer nursing home (NH) residents to emergency departments (EDs).

DESIGN

Three nursing homes (NHs) in Virginia were selected based on geographic and ownership variability. The phenomenon of concern was the decision-making process culminating in the transfer of NH residents to EDs. Sixteen transfers met the inclusion criteria and were analyzed. A minimum of two informants per transfer were interviewed, with a range of 2 to 4 interviews per transfer. All 42 respondents were asked to describe how the transfer decision was reached, to identify who participated in making the decision, and to describe any particular positive or negative aspects of reaching the transfer decision.

METHOD

Data were analyzed with hermeneutic phenomenological methods. Journal writing, audit trails, informal and formal member checks, and expert consultation were used to control bias.

FINDINGS

The three main themes identified were Consensus, Conflict, and Cogency. Consensus, or agreement, occurred when all decision participants reported similar interpretations as to the severity and acuity of the presenting problem or had shared interpretations of the best interests of the elder. When decision participants held dissimilar interpretations, conflict occurred. Decision participants used cogency by persuading others, in order to reach consensus.

CONCLUSIONS

The findings cannot be generalized to long-term care facilities across the US or to other countries, but they enhance understanding about some of the ways transfer decisions occur and the role of nurses in those transfers, especially when conflict arises.

Nursing Home–Associated Pneumonia

Nursing home-associated pneumonia (NHAP) is associated with considerable morbidity and mortality. The etiology of NHAP continues to be debated and has influenced treatment guideline recommendations. Diagnosis may not be straightforward but at least one respiratory symptom usually is present and the presence of hypoxemia is a key finding. Treatment recommendations vary depending on the organisms believed the predominant cause of NHAP. Pneumococcal and influenza vaccination remain the most important methods for prevention of NHAP at present.

Decisions to forgo hospitalization in advanced dementia: a nationwide study

OBJECTIVES

To examine the prevalence and factors associated with decisions to forgo hospitalization in nursing home (NH) residents with advanced dementia.

DESIGN

Cross-sectional study.

SETTING

All Medicare- and Medicaid-certified NHs within the 48 contiguous U.S. states.

PARTICIPANTS

NH residents with advanced dementia were identified using Minimum Data Set (MDS) assessments completed close to April 1, 2000 (N=91,521).

MEASUREMENTS

Multilevel, multivariate logistic regression identified factors independently associated with having a do-not-hospitalize (DNH) directive. Independent variables included subject characteristics (MDS), facility factors (On-line Survey of Certification of Automated Records), and hospital referral region (HRR) features (Dartmouth Atlas).

RESULTS

Nationwide, 7.1% (n=6,518) residents with advanced dementia had DNH orders (range 0.7% in Oklahoma to 25.9% in Rhode Island). Resident characteristics associated with having a DNH order were older age, white, living will, durable power of attorney for health care, and total functional dependence. Controlling for these factors, DNH orders were more likely in residents of facilities with the following features: not part of a chain, urban location, special care dementia unit, fewer black residents, nurse practitioner or physician assistant on staff, higher staffing ratios, and location in HRRs with fewer intensive care unit admissions during terminal hospitalizations.

CONCLUSION

Directives to forgo hospitalization for U.S. NH residents with advanced dementia are uncommon and are associated with the organizational features of the facilities caring for them and the intensity of end-of-life care practiced in the region, as well as individual resident characteristics.

Guidelines for the management of adults with health care-associated pneumonia: implications for nursing facility residents

OBJECTIVE

To review the implications for nursing facility residents of the 2005 American Thoracic Society (ATS)/Infectious Diseases Society of America (IDSA) guidelines for the Management of Adults with Health Care-Associated Pneumonia.

DATA SOURCE

A MEDLINE/PUBMED search (1986-February 2006) was conducted to identify pertinent studies of health care associated pneumonia acquired in the nursing facility setting (formerly called nursing home-acquired pneumonia) in the English language. Additional references were obtained from the bibliographies of these studies.

STUDY SELECTION AND DATA EXTRACTION

All studies evaluating any aspect of nursing home-acquired pneumonia.

DATA SYNTHESIS

Careful review of these guidelines will reveal a failure of the ATS/IDSA committee members to review the large published database available in the field of nursing home-acquired pneumonia. In addition, the committee was devoid of representation from experts in this field. As a result, these guidelines are applicable only to nursing facility residents admitted to the hospital. For the vast majority of nursing facility residents, these guidelines are problematic. The use of invasive means to acquire respiratory tract secretions for culture and susceptibility testing in the nursing facility setting is just not possible. Few facilities are able to manage residents with the two-, three-, or four-drug combination intravenous therapies recommended. As a result of these realities, all residents of nursing facilities with suspected pneumonia would be forced into hospital for diagnostic workup and at least initial empiric therapy if the guidelines were followed "to the letter." The guidelines do not even discuss the issue of site of treatment and how to select residents for outpatient (i.e., infacility) versus inpatient (i.e., in-hospital) management. Infacility management mandated by advanced directives is not even considered by the guidelines.

CONCLUSION

There does exist a database upon which the clinician can make informed decisions about likely pathogens, the probability that the resident actually has bacterial pneumonia, objective parameters suggesting the need for hospitalization for initial management, and guidance on when to initiate antimicrobial therapy, and which agent(s) to use. These issues are summarized here, and alternative, evidence-based, practical recommendations for the management of nursing home-acquired pneumonia are outlined.

Fluoroquinolone-resistant Escherichia coli in the long-term care setting

BACKGROUND

Prior studies have found fluoroquinolone exposure to be a risk factor for infection with fluoroquinolone-resistant gram-negative rods in the acute care setting. However, risk factors may be different in the long-term care setting.

METHODS

A case-control study design was used to determine whether fluoroquinolone exposure is a risk factor for fluoroquinolone-resistant Escherichia coli urinary tract infections in a long-term care center. Cases had fluoroquinolone-resistant E. coli urinary tract infections; 4 controls were selected for each case.

RESULTS

Thirty-three case patients were eligible; 132 controls were then selected. In the multivariable analysis, fluoroquinolone-resistant E. coli urinary tract infection was more common with prior fluoroquinolone use (odds ratio 21.8, 95% confidence interval, 3.7-127.1).

CONCLUSIONS

Prior fluoroquinolone use is a strong risk factor for fluoroquinolone-resistant E. coli urinary tract infection in the long-term care setting. Further studies are needed to examine the effect of interventions to decrease fluoroquinolone-resistant infections in the long-term care setting, including studying the effect of decreasing fluoroquinolone use.

Predictors of mortality for lower respiratory infections in nursing home residents with dementia were validated transnationally

BACKGROUND AND OBJECTIVE

Generalizability of clinical predictors for mortality from lower respiratory infection (LRI) in nursing home residents has not been assessed for residents with dementia.

STUDY DESIGN AND SETTING

In prospective cohort studies of LRI in 61 nursing homes in the Netherlands (n = 541) and 36 nursing homes in Missouri, USA (n = 564), we examined 14-day and 1- and 3-month mortality in residents with dementia who were treated with antibiotics.

RESULTS

A logistic model predicting 14-day mortality derived from Dutch data included eating dependency, elevated pulse, decreased alertness, respiratory difficulty, insufficient fluid intake, high respiratory rate, male gender, and pressure sores. After adjusting coefficients with the heuristic shrinkage factor, the 14-day model showed good discrimination and calibration in both datasets. The apparent c-statistic for the original Dutch model was 0.80 (after correction for optimism, it was 0.75); the c-statistic was 0.74 in the U.S. validation population. The models predicting 1- and 3-month mortality showed moderate performance. A scoring system for estimating 14-day mortality performed equally well as the original model.

CONCLUSION

We identified a set of credible clinical predictors that are easily assessed and demonstrated validity in identifying residents at low risk of dying from LRI across different nursing home populations. This tool should inform decision-making for families and doctors.

A cross-cultural study of physician treatment decisions for demented nursing home patients who develop pneumonia

PURPOSE

We wanted to explore factors that influence Dutch and US physician treatment decisions when nursing home patients with dementia become acutely ill with pneumonia.

METHODS

Using a qualitative semistructured interview study design, we collected data from 12 physicians in the Netherlands and 12 physicians in North Carolina who care for nursing home patients. Our main outcome measures were perceptions of influential factors that determine physician treatment decisions regarding care of demented patients who develop pneumonia.

RESULTS

Several themes emerged from the study. First, physicians viewed their patient care roles differently. Dutch physicians assumed active, primary responsibility for treatment decisions, whereas US physicians were more passive and deferential to family preferences, even in cases when they considered families' wishes for care as inappropriate. These family wishes were a second theme. US physicians reported a perceived sense of threat from families as influencing the decision to treat more aggressively, whereas Dutch physicians revealed a predisposition to treat based on what they perceived was in the best interest of the patient. The third theme was the process of decision making whereby Dutch physicians based decisions on an intimate knowledge of the patient, and American physicians reported limited knowledge of their nursing home patients as a result of lack of contact time.

CONCLUSION

Physician-perceived care roles regarding treatment decisions are influenced by contextual differences in physician training and health care delivery in the United States and the Netherlands. These results are relevant to the debate about optimal care for patients with poor quality of life who lack decision-making capacity.

Occurrence and treatment of suspected pneumonia in long-term care residents dying with advanced dementia

OBJECTIVES

To describe the occurrence and management of suspected pneumonia in end-stage dementia and to identify factors associated with aggressiveness of antibiotic treatment.

DESIGN

Retrospective cohort study.

SETTING

A 675-bed long-term-care facility in Boston, Massachusetts.

PARTICIPANTS

Two hundred forty subjects aged 65 and older who died with advanced dementia between January 2001 and December 2003. Subjects who had suspected pneumonia during the last 6 months of life were identified.

MEASUREMENTS

Independent variables included subject characteristics and features of suspected pneumonia episodes. These variables were obtained from medical records. Antibiotic treatment for each episode was determined. Multivariate analysis was used to identify independent variables associated with aggressiveness of treatment.

RESULTS

One hundred fifty-four (64%) subjects with advanced dementia experienced 229 suspected pneumonia episodes during the last 6 months of life. Within 30 days of death, 53% of subjects had suspected pneumonia. Antibiotic treatment for the 229 episodes was as follows: none, 9%; oral only, 37%; intramuscular, 25%; and intravenous, 29%. Factors independently associated with more-invasive therapy were lack of a do-not-hospitalize order (adjusted odds ratio (AOR) = 3.24, 95% confidence interval (CI) = 2.02-5.22), aspiration (AOR = 2.75, 95% CI = 1.44-5.26), primary language not English (AOR = 2.21, 95% CI = 1.17-4.15), and unstable vital signs (AOR = 2.02, 95% CI = 1.10-3.72).

CONCLUSION

Pneumonia is a common terminal event in advanced dementia for which many patients receive parenteral antibiotics. The aggressiveness of treatment is most strongly determined by advance care planning, the patient's cultural background, and clinical features of the suspected pneumonia episode.

Epidemiology of community- and nursing home-acquired pneumonia in older adults

Pneumococcus remains the most important cause of community-acquired pneumonia in older adults. Alcoholism, bronchial asthma, immunosuppression, lung disease, heart disease, institutionalization and increasing age are important risk factors. There is a reduced prevalence of nonrespiratory symptoms in this age group. Advanced age and comorbidity are important prognostic factors. Influenza and pneumococcal vaccination remain the key factors for prevention.

Nursing Home Capabilities and Decisions to Hospitalize: A Survey of Medical Directors and Directors of Nursing

OBJECTIVES

To obtain information from decision makers about attitudes toward hospitalization and the factors that influence their decisions to hospitalize nursing home residents.

DESIGN

Cross-sectional survey.

SETTING

Four hundred forty-eight nursing homes, 76% of which were nonprofit, from 25 states.

PARTICIPANTS

Medical directors and directors of nursing (DONs).

MEASUREMENTS

Participants were surveyed about resource availability, determinants of hospitalization, causes of overhospitalization, and nursing home practice.

RESULTS

The survey response rate was 81%, with at least one survey from 93% of the facilities. Medical directors and DONs agreed that resident preference was the most important determinant in the decision to hospitalize, followed by quality of life. Although both groups ranked on-site doctor/nurse practitioner evaluation within 4 hours as the least accessible resource, they did not rank doctors not being quickly available as an important cause of overhospitalization. Rather, medical directors perceived the lack of information and support to residents and families around end-of-life care and the lack of familiarity with residents by covering doctors as the most important causes of overhospitalization. DONs agreed but reversed the order. Medical directors and DONs expressed confidence in provider and staff ability, although DONs were significantly more positive.

CONCLUSION

Medical directors and DONs agree about most factors that influence decisions to hospitalize nursing home residents. Patient-centered factors play the largest roles, and the most important causes of overhospitalization are potentially modifiable.

A clinical pathway for treating pneumonia in the nursing home: part II: the administrators' perspective and how it differs from nurses' views

OBJECTIVES

This paper examines the utility and sustainability of a clinical pathway for treating nursing home residents with pneumonia from the perspective of nursing administrators and medical directors in Ontario, Canada. The discussion includes a comparison of the perspectives of the administrators and the nursing staff (reported in part I of this article).

DESIGN

A qualitative case study design was used.

SETTING

Data were collected from 6 nursing homes in Southern Ontario that were drawn from a larger randomized controlled trial of a clinical pathway to help identify, diagnose, and manage cases of nursing home-acquired pneumonia.

PARTICIPANTS

Six interviews were conducted with nursing administrators and 2 with medical directors (1 per facility). Key themes were identified in the interview data using the template style of analysis described by Miller and Crabtree.

FINDINGS

Administrators were in favor of using a clinical pathway for identifying and treating pneumonia in nursing home residents. Participants thought that during the study residents with pneumonia received better and more timely care, and that nurses' clinical skills, knowledge, and confidence had improved. In comparison with views expressed by nurses and medical directors in the same facilities, nursing administrators tended to report less clinical training and staff support were required to successfully implement the pathway.

CONCLUSIONS

Even though nurses and administrators strongly support the use of a pneumonia clinical pathway in nursing homes, implementation plans should be tailored to individual facilities and be informed by the perspectives of both administrators and staff.

A clinical pathway for treating pneumonia in the nursing home: part I: the nursing perspective

OBJECTIVES

This paper examines nursing staff's perspectives on the utility and sustainability of a clinical pathway for treating nursing home residents with pneumonia.

DESIGN

A qualitative (case study) design was used.

SETTING

Data were collected from 6 nursing homes in Southern Ontario (5 from metro regions and 1 from a nonmetro region). Nursing homes were drawn from a larger randomized controlled trial of a clinical pathway for nursing home-acquired pneumonia conducted between 2001 and 2005. The clinical pathway was designed to assist in the identification, diagnosis, and management of pneumonia, including a decision tool for determining the appropriate location of treatment (hospital versus nursing home).

PARTICIPANTS

A total of 7 focus groups and 1 one-on-one interview were conducted between February 2003 and May 2004. Interview data were analyzed using the template style, described by Miller and Crabtree, to identify key themes.

FINDINGS

Nurses strongly supported the idea of the clinical pathway and believed that providing pneumonia care in the nursing home was better for the resident. As a result of using the clinical pathway, nurses felt that pneumonia was being identified, diagnosed, and treated earlier, resulting in fewer hospitalizations. In addition to the benefits to resident care, the nurses felt that their skills and knowledge also improved. Nurses generally supported the implementation of the pathway although some concern was expressed about the additional responsibility and resources that would entail.

CONCLUSIONS

The implementation of a clinical pathway for treating pneumonia in nursing homes and quick access to a backup clinician are desired by nurses who also believe it will result in better care and fewer hospitalizations of residents.

Pneumonia care and the nursing home: a qualitative descriptive study of resident and family member perspectives

BACKGROUND

Nursing home residents are frequently sent to hospital for diagnostic tests or to receive acute health care services. These transfers are both costly and for some, associated with increased risks. Although improved technology allows long-term care facilities to deliver more complex health care on site, if this is to become a trend then residents and family members must see the value of such care. This qualitative study examined resident and family member perspectives on in situ care for pneumonia.

METHODS

A qualitative descriptive study design was used. Participants were residents and family members of residents treated for pneumonia drawn from a larger randomized controlled trial of a clinical pathway to manage nursing home-acquired pneumonia on-site. A total of 14 in-depth interviews were conducted. Interview data were analyzed using the editing style, described by Miller and Crabtree, to identify key themes.

RESULTS

Both residents and family members preferred that pneumonia be treated in the nursing home, where possible. They both felt that caring and attention are key aspects of care which are more easily accessible in the nursing home setting. However, residents felt that staff or doctors should make the decision whether to hospitalize them, whereas family members wanted to be consulted or involved in the decision-making process.

CONCLUSION

These findings suggest that interventions to reduce hospitalization of nursing home residents with pneumonia are consistent with resident and family member preferences.

Nursing Home-Acquired Pneumonia

The management of nursing home-acquired pneumonia (NHAP) continues to be debatable because of the lack of clinical trials and controversy regarding its aetiology. The controversy regarding aetiology stems, in part, from studies that utilised sputum cultures for the diagnosis of NHAP without assessing the quality of the samples. These studies found a high proportion of Gram-negative aerobic bacilli in cultures as well as Staphylococcus aureus. However, in studies that have assessed the reliability of sputum samples, Gram-negative bacilli and S. aureus were isolated infrequently and Streptococcus pneumoniae and Haemophilus influenzae isolated most commonly. Since Gram-negative aerobic bacilli and S. aureus frequently cause hospital-acquired pneumonia, some authors have considered NHAP to be a variant of this group. Many other studies, however, have considered NHAP as part of the community-acquired pneumonia category. Depending on which categorisation is used for NHAP, the treatment recommendations have varied. There are several factors to consider in the management of NHAP in addition to choice of antibacterial: hospitalisation decision, initial route of administration of antibacterials for treatment in the nursing home, timing of switch from a parenteral to an oral agent and the duration of therapy. These factors, which have not been addressed in published guidelines, are discussed in this review. Recent guidelines recommend a fluoroquinolone (gatifloxacin, levofloxacin or moxifloxacin) or amoxicillin/clavulanic acid plus a macrolide for initial treatment of NHAP in the nursing home. For treatment in the hospital, a parenteral fluoroquinolone (as listed above) or a second- or third-generation cephalosporin plus a macrolide is recommended. A recent guideline for the treatment of healthcare-associated pneumonia (that includes NHAP) recommended an antipseudomonal cephalosporin or a carbapenem or an antipseudomonal penicillin/beta-lactamase inhibitor plus ciprofloxacin plus vancomycin or linezolid for treatment of NHAP based on findings in residents with severe pneumonia who required mechanical ventilation. However, this recommendation does not apply to the majority of residents who are hospitalised with pneumonia and not intubated. Other factors to consider when choosing an empiric regimen include recent antibacterial therapy and prior colonisation with a resistant organism, e.g. methicillin-resistant S. aureus. Recently, a group of studies by investigators in The Netherlands have focused on the concept of withholding antibacterial therapy in nursing home residents with pneumonia who have advanced dementia. These studies are reviewed in some detail because this is an approach to the management of NHAP that is uncommon but deserves more consideration given the terminal status of these people. Future studies of NHAP should focus on development of rapid (molecular) methods to identify aetiological agents, determination of the optimum antimicrobial regimen and duration of therapy, and identification of criteria that can assist physicians and families in making the decision to withhold antimicrobial therapy in residents with advanced dementia and pneumonia.

Preventing infections in nursing homes: a survey of infection control practices in southeast Michigan

BACKGROUND

Studies on adherence to infection control policies in nursing homes (NHs) are limited. This pilot study explores the use of various infection control practices and the role of infection control practitioners in southeast Michigan NHs.

METHODS

A 43-item self-administered questionnaire and explanatory cover letter were mailed to 105 licensed NHs in southeast Michigan. A second mailing was sent to the nonresponders 4 weeks later.

RESULTS

Significant variability existed in adoption of various infection control measures with respect to time spent in infection control activities (50% of facilities having a full-time infection control practitioner), definitions used in monitoring infections, and immunization rates (influenza: range, 0%-100%; mean, 73.2%; pneumococcal: range, 0%-100%; mean, 38.5%).

CONCLUSION

Although strides have been made in infection control research in NHs, significant variations exist in implementation of infection control methods and guidelines. Future research should focus on identifying barriers to infection control in NHs.

Decisions to Hospitalize Nursing Home Residents Dying with Advanced Dementia

OBJECTIVES

To describe the prevalence of, timing of, and factors associated with decisions not to hospitalize nursing home residents with advanced dementia who were dying.

DESIGN

Retrospective cohort study.

SETTING

Six hundred seventy five-bed nursing facility in Boston.

PARTICIPANTS

Two hundred forty residents in a teaching nursing home who died between January 2001 and December 2003 with advanced dementia.

MEASUREMENTS

The prevalence and timing of do-not-hospitalize (DNH) orders were determined from the medical record. Data describing demographic characteristics, health conditions, advance care planning, sentinel events, and health services usage during the last 6 months of life were examined. Factors associated with having a DNH order were identified.

RESULTS

At the time of death, 83.8% of subjects had a DNH order. The prevalence of DNH orders was 50.0% and 34.4%, 30 and 180 days before death, respectively. Hospital transfers were common during the last 6 months of life (24.6%). Factors independently associated with having a DNH order before death included surrogate decision-maker was not the subject's child (adjusted odds ratio (AOR)=4.39, 95% confidence interval (CI)=1.52-12.66), eating problems (AOR=4.17, 95% CI=1.52-11.47), aged 92 and older (AOR=2.78, 95% CI=1.29-5.96), and length of stay 2 years or longer (AOR=2.34, 95% CI=1.11-4.93).

CONCLUSION

For most institutionalized persons with advanced dementia, a decision to forgo hospitalization is not made until death is imminent. Thus, hospital transfers are common near the end of life. The finding that DNH orders are associated with patient and surrogate factors can help clinicians identify cases in which decisions to forgo hospitalizations may be facilitated.
