Balance and Fall Risk Assessment in Community-Dwelling Older Adults after Recovery from COVID-19: A Cross-Sectional Study. Sports (Basel) 2023; 11:sports11020028. [PMID: 36828313 PMCID: PMC9967781 DOI: 10.3390/sports11020028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2022] [Revised: 12/02/2022] [Accepted: 01/19/2023] [Indexed: 01/31/2023] Open
Abstract
BACKGROUND SARS-CoV-2 atypical symptoms in older persons include falls, confusion, dizziness, and unusual weariness. Falls and their consequences are among the most prevalent causes of disability among older adults, significantly lowering quality of life and resulting in the loss of independence as well as impaired psychosocial functioning. The study purpose was to examine the impact of the SARS-CoV-2 infectious disease on balance in community-dwelling older adults. METHODS Sixty-four older adults aged ≥ 60 years from both sexes, 31 treated for SARS-CoV-2 infection and 33 matched normal controls participated in the study. The Biodex Stability System (BSS) and Berg Balance Scale (BBS) were used for evaluation of balance and fall risk. The correlation between the Biodex overall stability index and the Berg Balance Scale score was investigated. RESULTS When compared to controls, the SARS-CoV-2 group had significantly higher values of the Biodex overall stability index (OSI) (p = 0.011), anterior-posterior stability index (APSI) (p = 0.013), mediolateral stability index (MLSI) (p = 0.018), and fall risk index (FRI) (p = 0.008), as well as statistically lower scores on the Berg balance scale (p = 0.003). A moderate negative correlation was found between the two assessment tools in the SARS-CoV-2 group. CONCLUSION Balance impairment and an increased risk of falling are among the outcomes of SARS-CoV-2 in community-dwelling older adults.

Abstract
BACKGROUND Delirium is an acute cognitive impairment among older hospitalized patients. It can persist until discharge and for months after that. Despite proof that evidence-based nursing interventions are effective in preventing delirium in acute hospitals, interventions among home-dwelling older patients is lacking. The aim was to assess feasibility and acceptability of a nursing intervention designed to detect and reduce delirium in older adults after discharge from hospital. METHODS Randomized clinical pilot trial with a before/after design was used. One hundred and three older adults were recruited in a home healthcare service in French-speaking Switzerland and randomized into an experimental group (EG, n = 51) and a control group (CG, n = 52). The CG received usual homecare. The EG received usual homecare plus five additional nursing interventions at 48 and 72 h and at 7, 14 and 21 days after discharge. These interventions were tailored for detecting and reducing delirium and were conducted by a geriatric clinical nurse (GCN). All patients were monitored at the start of the study (M1) and throughout the month for symptoms of delirium (M2). This was documented in patients' records after usual homecare using the Confusion Assessment Method (CAM). At one month (M2), symptoms of delirium were measured using the CAM, cognitive status was measured using the Mini-Mental State Examination (MMSE), and functional status was measured using Katz and Lawton Index of activities of daily living (ADL/IADL). At the end of the study, participants in the EG and homecare nurses were interviewed about the acceptability of the nursing interventions and the study itself. RESULTS Feasibility and acceptability indicators reported excellent results. Recruitment, retention, randomization, and other procedures were efficient, although some potentially issues were identified. Participants and nurses considered organizational procedures, data collection, intervention content, the dose-effect of the interventions, and methodology all to be feasible. Duration, patient adherence and fidelity were judged acceptable. Nurses, participants and informal caregivers were satisfied with the relevance and safety of the interventions. CONCLUSIONS Nursing interventions to detect/improve delirium at home are feasible and acceptable. These results confirm that developing a large-scale randomized controlled trial would be appropriate. TRIAL REGESTRATION ISRCTN registry no: 16103589 - 19 February 2016.

Abstract
This review examines ways to decrease preventable effects of hospitalization on older adults in acute care medical (non-geriatric) units, with a focus on the Israeli experience at the Rambam Health Care Campus, a large tertiary care hospital in northern Israel. Hospitalization of older adults is often followed by an irreversible decline in functional status affecting their quality of life and well-being after discharge. Functional decline is often related to avoidable effects of in-hospital procedures not caused by the patient's acute disease. In this article we review the literature relating to the recognized effects of hospitalization on older adults, pre-hospitalization risk factors, and intervention models for hospitalized older adults. In addition, this article describes an Israeli comprehensive research study, the Hospitalization Process Effects on Functional Outcomes and Recovery (HoPE-FOR), and outlines the design of a combined intervention model being implemented at the Rambam Health Care Campus. The majority of the reviewed studies identified preadmission personal risk factors and psychosocial risk factors. In-hospital restricted mobility, under-nutrition care, over-use of continence devices, polypharmacy, and environmental factors were also identified as avoidable processes. Israeli research supported the findings that preadmission risk factors together with in-hospital processes account for functional decline. Different models of care have been developed to maintain functional status. Much can be achieved by interdisciplinary teams oriented to the needs of hospitalized elderly in making an impact on hospital processes and continuity of care. It is the responsibility of health care policy-makers, managers, clinicians, and researchers to pursue effective interventions to reduce preventable hospitalization-associated disability.

Abstract
Hospitalization is a risk for elderly population, with a high probability of having adverse events. The most important one is functional impairment, due to its high prevalence and the serious impact it has on the quality of life. The main risk factors for functional decline associated with hospitalization are, age, immobility, cognitive impairment, and functional status prior to admission. It is necessary to detect patients at risk in order to implement the necessary actions to prevent this deterioration, with physical exercise and multidisciplinary geriatric care being the most important.

Abstract
BACKGROUND The Patient Navigation Research Program (PNRP) is a cooperative effort of nine research projects, with similar clinical criteria but with different study designs. To evaluate projects such as PNRP, it is desirable to perform a pooled analysis to increase power relative to the individual projects. There is no agreed-upon prospective methodology, however, for analyzing combined data arising from different study designs. Expert opinions were thus solicited from the members of the PNRP Design and Analysis Committee. PURPOSE To review possible methodologies for analyzing combined data arising from heterogeneous study designs. METHODS The Design and Analysis Committee critically reviewed the pros and cons of five potential methods for analyzing combined PNRP project data. The conclusions were based on simple consensus. The five approaches reviewed included the following: (1) analyzing and reporting each project separately, (2) combining data from all projects and performing an individual-level analysis, (3) pooling data from projects having similar study designs, (4) analyzing pooled data using a prospective meta-analytic technique, and (5) analyzing pooled data utilizing a novel simulated group-randomized design. RESULTS Methodologies varied in their ability to incorporate data from all PNRP projects, to appropriately account for differing study designs, and to accommodate differing project sample sizes. LIMITATIONS The conclusions reached were based on expert opinion and not derived from actual analyses performed. CONCLUSIONS The ability to analyze pooled data arising from differing study designs may provide pertinent information to inform programmatic, budgetary, and policy perspectives. Multisite community-based research may not lend itself well to the more stringent explanatory and pragmatic standards of a randomized controlled trial design. Given our growing interest in community-based population research, the challenges inherent in the analysis of heterogeneous study design are likely to become more salient. Discussion of the analytic issues faced by the PNRP and the methodological approaches we considered may be of value to other prospective community-based research programs.

Abstract
BACKGROUND Hospitalization is the first cause of functional decline in the elderly: 30 to 60% of elderly patients lose some independence in basic activities of daily living (ADL) during a stay in hospital. This loss of independence results from the acute condition that led to admission, but is also related to the mode of management. OBJECTIVE This paper is a review of the literature on functional decline in elderly hospitalized patients. It is the first stage in a project aiming to prevent dependence that is induced during the course of care. METHODS During a 2-day workshop in Monaco, a task force of 20 international experts discussed and defined the concept of "iatrogenic disability". RESULTS 1- "Iatrogenic disability" was defined by the task force as the avoidable dependence which often occurs during the course of care. It involves three components that interact and have a cumulative effect: a) the patient's pre-existing frailty, b) the severity of the disorder that led to the patient's admission, and lastly c) the hospital structure and the process of care. 2- The prevention of "iatrogenic disability" involves successive stages. - becoming aware that hospitalization may induce dependence. Epidemiological studies have identified at-risk populations by the use of composite scores (HARP, ISAR, SHERPA, COMPRI, etc). - considering that functional decline is not a fatality. Quality references have already been defined. Interventions to prevent dependence in targeted populations have been set up: simple geriatric consultation teams, single-factor interventions (aimed for example at mobility, delirium, iatrogenic disorders) or multidomain interventions (such as GEM and ACE units, HELP, Fast Track, NICHE). These interventions are essentially centered on the patient's frailty and have limited results, as they take little account of the way the institution functions, which is not aimed at prevention of functional decline. The process of care reveals shortcomings: lack of geriatric knowledge, inadequate evaluation and management of functional status. The group suggests that interventions must not only identify at-risk patients so that they may benefit from specialized management, but they must also target the hospital structure and the process of care. This requires a graded "quality approach" and rethinking of the organization of the hospital around the elderly person.

Abstract
BACKGROUND Prospective meta-analysis (PMA) is a collaborative research design in which individual sites perform randomized controlled trials (RCTs) and pool the data for meta-analysis. Members of the PMA collaboration agree upon specific research interventions and outcome measures, ideally before initiation but at least prior to any individual trial publishing results. This allows for uniform reporting of primary and secondary outcomes. With this approach, heterogeneity among trials contributing data for the final meta-analysis is minimized while each site maintains the freedom to design a specific trial. This paper describes the process of creating a PMA collaboration to evaluate the impact of misoprostol on ease of intrauterine device (IUD) insertion in nulliparous women. METHODS After the principal investigator developed a preliminary PMA protocol, he identified potential collaborating investigators at other sites. One site already had a trial underway and another site was in the planning stages of a trial meeting PMA requirements. Investigators at six sites joined the PMA collaborative. Each site committed to enroll subjects to meet a pre-determined total sample size. A final common research plan and site responsibilities were developed and agreed upon through email and face-to-face meetings. Each site committed to contribute individual patient data to the PMA collaboration, and these data will be analyzed and prepared as a multi-site publication. Individual sites retain the ability to analyze and publish their site's independent findings. RESULTS All six sites have obtained Institutional Review Board approval and each has obtained individual funding to meet the needs of that site's study. Sites have shared resources including study protocols and consents to decrease costs and improve study flow. This PMA protocol is registered with the Cochrane Collaboration and data will be analyzed according to Cochrane standards for meta-analysis. CONCLUSIONS PMA is a novel research method that improves meta-analysis by including several study sites, establishing uniform reporting of specific outcomes, and yet allowing some independence on the part of individual sites with respect to the conduct of research. The inclusion of several sites increases statistical power to address important clinical questions. Compared to multi-center trials, PMA methodology encourages collaboration, aids in the development of new investigators, decreases study costs, and decreases time to publication.

Abstract
Although the implementation of acute geriatric units (AGUs) in general hospitals has a grade A of evidency, in Spain, only 12% of them have this resource. The estimation of geriatric especializad beds for the care of acute frail elderly people is of 2.6/1000 inhabitants older than 75 years. AGUs have demonstrated to reduce the functional loss associated with the hospitalization and to increase the percentage of older people that can return home, without increases in mortality nor costs. In this review we present the characteristics of patients who benefit from AGUs, the services offered, the structure and functioning of the unit, the role of the professionals that work in it and the quality indicators that must be acomplished.

Abstract
BACKGROUND Life space is a measure of where a person goes, the frequency of going there, and the dependency in getting there. It may be a more accurate measure of mobility in older adults because it reflects participation in society as well as physical ability. OBJECTIVE To assess effects of hospitalization on life space in older adults, and to compare life-space trajectories associated with surgical and nonsurgical hospitalizations. DESIGN Prospective observational study. SETTING Central Alabama. PARTICIPANTS 687 community-dwelling Medicare beneficiaries at least 65 years of age with surgical (n = 44), nonsurgical (n = 167), or no (n = 476) hospitalizations. MEASUREMENTS Life-Space Assessment (LSA) scores before and after hospitalization (range, 0 to 120; higher scores reflect greater mobility). RESULTS Mean age of participants was 74.6 years (SD, 6.3). Fifty percent were black, and 46% were male. Before hospitalization, adjusted LSA scores were similar in participants with surgical and nonsurgical admissions. Life-space assessment scores decreased in both groups immediately after hospitalization; however, participants with surgical hospitalizations had a greater decrease in scores (12.1 more points [95% CI, 3.6 to 20.7 points]; P = 0.005) than those with nonsurgical hospitalizations. However, participants with surgical hospitalizations recovered more rapidly over time (gain of 4.7 more points [CI, 2.0 to 7.4 points] per ln [week after discharge]; P < 0.001). Score recovery for participants with nonsurgical hospitalizations did not significantly differ from the null (average recovery, 0.7 points [CI, -0.6 to 1.9 points] per ln [week after discharge]). LIMITATION Life space immediately before and after hospitalization was self-reported, often after hospital discharge. CONCLUSION Hospitalization decreases life space in older adults. Surgical hospitalizations are associated with immediate marked life-space declines followed by rapid recovery, in contrast to nonsurgical hospitalizations, which are associated with more modest immediate declines and little evidence of recovery after several years of follow-up.

Abstract
INTRODUCTION In some elderly individuals, hospital admission for acute illness represents a possible loss of autonomy not always related to the reason for hospitalization. The importance of this problem and the possible existence of differences among services are not sufficiently well known. OBJECTIVE To compare the incidence of functional decline and associated risk factors during hospitalization between an acute care geriatric unit (GU) and an internal medicine (IM) ward. MATERIAL AND METHODS We performed a prospective, cohort study. Sociodemographic characteristics, comorbidity, cause of admission, severity, use of several hospital practices, mortality rate and functional decline were analyzed. Functional decline was defined as the loss of independence to perform at least one of the basic activities of daily living with respect to preadmission status. The influence of the admitting service was evaluated by a multiple logistic regression model. RESULTS A total of 379 patients were included (140 in the GU and 239 in IM). Compared with IM, patients in the GU were older (87 vs 81.5; P< .001), had a greater prevalence of dementia and visual alterations and worse previous functional status. The proportion of patients who spent > 48 hours in bed and who received nocturnal medication was lower in the GU. The functional decline rate was greater in IM than in the GU (60.2% vs 48%; P=.04). Length of hospital stay was similar in both groups (7.7 vs 8.1 days; P=.37). Functional decline was associated with age, delirium, lack of mobilization, bed rest for > 48 h, psychotropic drugs, nocturnal medication and physical restraints. In the multivariate analysis, admission to IM was associated with a greater risk of functional decline. CONCLUSIONS Functional decline during hospitalization for acute diseases is frequent among frail patients. Many modifiable clinical practices are associated with this complication. In patients at risk of delirium, admission to geriatric wards may be associated with less functional deterioration than admission to internal medicine wards.

Abstract
Older adults are at risk for losing functional ability during and after a hospitalization. It's often difficult to determine which patients are at highest risk and which might benefit from targeted interventions. The Hospital Admission Risk Profile, a simple screening tool, can be used to classify hospitalized older adults as being at low, intermediate, or high risk for losing the ability to perform activities of daily living, based on assessments of age, cognitive function, and the ability to perform independent activities of daily living. It's one of many tools profiled in Try This: Best Practices in Nursing Care to Older Adults, a series provided by the Hartford Institute for Geriatric Nursing at New York University's College of Nursing.

Abstract
Background Hospitalization for older patients with community-acquired pneumonia (CAP) is associated with functional decline. Little is know about the relationship between inflammatory markers and determinants of functional status in this population. The aim of the study is to investigate the association between tumor necrosis factor (TNF)-α, C-reactive protein (CRP) and Activities of Daily Living, and to identify risk factors associated with one year mortality or hospital readmission. Methods 301 consecutive patients hospitalized for CAP (mean age 73.9 ± 5.3 years) in a University affiliated hospital over 18 month period were included. All patients were evaluated on admission to identify baseline demographic, microbiological, cognitive and functional characteristics. Serum levels for TNF-α and CRP were collected at the same time. Reassessment of functional status at discharge, and monthly thereafter till 3 months post discharge was obtained and compared with preadmission level to document loss or recovery of functionality. Outcome was assessed by the composite endpoint of hospital readmission or death from any cause up to one year post hospital discharge. Results 36% of patients developed functional decline at discharge and 11% had persistent functional impairment at 3 months. Serum TNF-α (odds ratio [OR] 1.12, 95% CI 1.08–1.15; p < 0.001) and the Charlson Index (OR = 1.39, 95% CI 1.14 to 1.71; p = 0.001) but not age, CRP, or cognitive status were independently associated with loss of functionality at the time of hospital discharge. Lack of recovery in functional status at 3 months was associated with impaired cognitive ability and preadmission comorbidities. In Cox regression analysis, persistent functional impairment at 3 months, impaired cognitive function, and the Charlson Index were highly predictive of one year hospital readmission or death. Conclusion Serum TNF-α levels can be useful in determining patients at risk for functional impairment following hospitalization from CAP. Old patients with impaired cognitive function and preexisting comorbidities who exhibit delay in functional recovery at 3 months post discharge may be at high risk for hospital readmission and death. With the scarcity of resources, a future risk stratification system based on these findings might be proven helpful to target older patients who are likely to benefit from interventional strategies.

Abstract
Introduction: Older persons are likely to develop functional impairment following hospitalisation. Several studies in the West have examined the factors associated with functional decline following the older person’s discharge from hospital but there are little data on Asian populations. This study aims to look at the associated risk factors in our local population, following admission to an acute geriatric unit.
Materials and Methods: This is a retrospective, cohort study. Patients who were discharged from an inpatient geriatric unit over a 3-month period were recruited. Data including their demographic information, functional status prior to admission and at the time of discharge, and medical conditions were obtained from the inpatient medical notes. A follow-up telephone interview was conducted at 3 months to determine the functional status of these patients at that point in time.
Results: Following hospitalisation, 40.4% of patients developed functional decline. Of those discharged, 29.6% showed functional decline at 3 months. The principal diagnosis, hypoalbuminaemia, tendency to fall, premorbid functional independence and the length of hospitalisation were associated with functional decline during hospitalisation, while hypoalbuminaemia, the presence of bedsores, institutionalisation, the length of hospitalisation and premorbid functional dependence were important factors associ- ated with functional decline between the time of discharge and 3 months after. In the multivari- able predictive model, independent predictors of functional decline at the time of discharge included patient’s tendency to fall, premorbid functional independence and the length of hospitalisation, while the presence of bedsores was the only significant predictor of functional decline 3 months post-discharge.
Conclusions: Many elderly patients developed new functional impairment following hospitalisation. Several factors were found to be associated with this functional decline, though no single predictive model similar to the other published studies was identified.

Abstract
OBJECTIVE To determine the independent contribution of admission delirium to hospital outcomes including mortality, institutionalization, and functional decline. DESIGN Three prospective cohort studies. SETTING Three university-affiliated teaching hospitals. PATIENTS Consecutive samples of 727 patients, aged 65 years and older. MEASUREMENTS AND MAIN RESULTS Delirium was present at admission in 88 (12%) of 727 patients. The main outcome measures at hospital discharge and 3-month follow-up were death, new nursing home placement, death or new nursing home placement, and functional decline. At hospital discharge, new nursing home placement occurred in 60 (9%) of 692 patients, and the adjusted odds ratio (OR) for delirium, controlling for baseline covariates of age, gender, dementia, APACHE II score, and functional measures, was 3.0, (95% confidence interval [CI] 1.4, 6.2). Death or new nursing home placement occurred in 95 (13%) of 727 patients (adjusted OR for delirium 2.1, 95% CI 1.1, 4.0). The findings were replicated across all sites. The associations between delirium and death alone (in 35 [5%] of 727 patients) and between delirium and length of stay were not statistically significant. At 3-month follow-up, new nursing home placement occurred in 77 (13%) of 600 patients (adjusted OR for delirium 3.0; 95% CI 1.5, 6.0). Death or new nursing home placement occurred in 165 (25%) of 663 patients (adjusted OR for delirium 2.6; 95% CI 1.4, 4.5). The findings were replicated across all sites. For death alone (in 98 [14%] of 680 patients), the adjusted OR for delirium was 1.6 (95% CI 0.8, 3.2). Delirium was a significant predictor of functional decline at both hospital discharge (adjusted OR 3.0; 95% CI 1.6, 5.8) and follow-up (adjusted OR 2.7; 95% CI 1.4, 5.2). CONCLUSIONS Delirium is an important independent prognostic determinant of hospital outcomes including new nursing home placement, death or new nursing home placement, and functional decline-even after controlling for age, gender, dementia, illness severity, and functional status. Thus, delirium should be considered as a prognostic variable in case-mix adjustment systems and in studies examining hospital outcomes in older persons.

Abstract
OBJECTIVES To develop and validate an instrument for stratifying older patients at the time of hospital admission according to their risk of developing new disabilities in activities of daily living (ADL) following acute medical illness and hospitalization. DESIGN Multi-center prospective cohort study. SETTING Four university and two private non-federal acute care hospitals. PATIENTS The development cohort consists of 448 patients and the validation cohort consists of 379 patients who were aged 70 and older and who were hospitalized for acute medical illness between 1989 and 1992. MEASUREMENTS All patients were evaluated on hospital admission to identify baseline demographic and functional characteristics and were then assessed at discharge and 3 months after discharge to determine decline in ADL functioning. RESULTS Logistic regression analysis identified three patient characteristics that were independent predictors of functional decline in the development cohort: increasing age, lower admission Mini-Mental Status Exam scores, and lower preadmission IADL function. A scoring system was developed for each predictor variable and patients were assigned to low, intermediate, and high risk categories. The rates of ADL decline at discharge for the low, intermediate, and high risk categories were 17%, 28%, and 56% in the development cohort and 19%, 31%, and 55% in the validation cohort, respectively. Patients in the low risk category were significantly more likely to recover ADL function and to avoid nursing home placement during the 3 months after discharge. CONCLUSION Hospital Admission Risk Profile (HARP) is a simple instrument that can be used to identify patients at risk of functional decline following hospitalization. HARP can be used to identify patients who might benefit from comprehensive discharge planning, specialized geriatric care, and experimental interventions designed to prevent/reduce the development of disability in hospitalized older populations.

Abstract
Meta-analyses of randomized trials evaluating cholesterol-lowering therapy have demonstrated clear reductions in coronary events and coronary mortality. However, the treatment impact on total mortality has been less certain. With the variable selection of trials and treatment questions, results of meta-analyses have sometimes given conflicting conclusions regarding the magnitude of treatment effects and the populations to whom benefits might accrue. Prospective meta-analysis can avoid these problems by clearly specifying the research questions, eligible studies, analysis plans, and outcome definitions in advance of trial results publication. This approach has been adopted in 2 major prospective meta-analyses of cholesterol-lowering treatments: the Prospective Pravastatin Pooling (PPP) project and the Cholesterol Treatment Trialists (CTT) collaboration. The PPP project is a prospectively planned combined analysis of 3 large-scale pravastatin trials comparing pravastatin against placebo over a minimum 5-year period. The analysis will contain data for > 19,500 patients and should have the power to examine the effects of treatment on total mortality, coronary mortality, and incidence of cancers as well as the ability to look at total coronary events in important subgroups underrepresented in previous trials. The CTT collaboration is a planned prospective meta-analysis of 12 major ongoing or planned randomized trials evaluating therapy with 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors, a fibrate, or dietary modification. The trials were prospectively registered and the CTT protocols became final in November 1994. By the year 2000, the CTT collaboration is projected to have information on about 65,000 patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
This paper reports a prospective study, carried out in elderly patients hospitalized for acute illness, designed to evaluate the effectiveness of medical treatment from the point of view of quality of life (QoL). Patient's autoperception and satisfaction with health, the most relevant subjective estimates of QoL, were assessed on admission to hospital and at check-up after discharge. A comprehensive functional evaluation of the patients was made. The results indicated an improvement in health autoperception coherent with the professional view. However, health satisfaction was not modified in any way after medical treatment. This dissonance could be explained because the predictors of satisfaction, age, sex, functional status and comorbidity, are the factors least modified by treatment. Satisfaction with ones own health could be a crucial marker of QoL especially for chronic diseases, but not appropriate for monitoring treatment effectiveness of acute illness. Health autoperception seems to be more desirable as an outcome estimate for this purpose.

Abstract
OBJECTIVE To describe the unique aspects of and the lessons learned in planning and conducting a pooled analysis of multiple trials evaluating interventions to reduce functional decline in hospitalized older persons. Specific examples from the Hospital Outcomes Project for the Elderly (HOPE) meta-analysis are discussed. DESIGN A prospective meta-analysis (PMA) that compiled and pooled data from concurrently conducted clinical trials testing related but distinct interventions. SETTING The Data Coordinating Center for the prospective meta-analysis coordinated the collection and analysis of common outcome data from five university-affiliated hospitals and one community hospital conducting the clinical trials. PARTICIPANTS Acutely ill hospitalized elderly participants at least 65 to 75 years old. INTERVENTIONS Treatments being evaluated included exercise, physical therapy, a multidisciplinary geriatric care unit, a multidisciplinary in-hospital intervention with post-discharge care, a nursing-based geriatric care program, and a program to improve detection and evaluation of delirious patients. CONCLUSION The prospective meta-analysis provides selected advantages over independently conducted clinical trials and retrospective meta-analyses. It does, however, pose special design and operational challenges that must be addressed well before initiation of the individual trials. Specific issues of concern include: maintaining scientific integrity of both the individual trials and the PMA; reaching consensus on PMA goals, what data to collect, how and when to collect them and how to maintain uniformly high quality data across all sites; defining the role of the Data Coordinating Center in a multicenter project that utilizes different trials and protocols; and establishing policies concerning analyses of the pooled data, publication of pooled analyses, and ownership of the pooled database.

Abstract
OBJECTIVE The purpose of this study was fourfold; to determine the rate of delirium among hospitalized older persons, to contrast the clinical outcomes of patients with and without delirium, to identify clinical predictors of delirium, and to validate the predictive model in an independent sample of patients. DESIGN Two prospective cohort studies SETTING Medical and surgical wards of 2 university teaching hospitals. PATIENTS In the derivation cohort, 432 patients were enrolled from the University of Chicago Hospitals. Patients 65 years of age or older admitted to 1 of 4 wards were eligible. Subjects were excluded if they were discharged within 48 hours of admission, unavailable to the research assistants during the first 2 days of hospitalization, or judged too impaired to participate in the daily interviews. In the test cohort, 323 patients 70 years of age or older admitted to Yale-New Haven Hospital were studied. MEASUREMENTS Subjects were screened for delirium daily and referred to experienced clinician investigators if acute mental status changes were observed. The clinician investigators assessed the patient for delirium based on DSM-III-R criteria. Duration of hospitalization was adjusted for diagnosis-related groups (DRG) and mortality rates were determined at discharge and 90 days after discharge. Sociodemographic characteristics, cognitive and functional status, comorbidity, depression, and alcoholism were examined as predictors of delirium. MAIN RESULTS The rate of delirium in the derivation cohort was 15%; subjects with delirium had longer hospital stays and an increased risk of in-hospital death. Cognitive impairment, burden of comorbidity, depression, and alcoholism were found to be independent predictors of delirium. The ability of the model to stratify patients as low, moderate, or high risk for developing delirium was validated in the test cohort in which the rate of delirium was 26%. CONCLUSIONS This study confirms the high rate of delirium among hospitalized older persons and the associated adverse outcomes of prolonged hospital stays and increased risk of death. Patients can be stratified according to their risk for developing delirium using relatively few clinical characteristics which should be assessed, on all hospitalized older persons.

Abstract
Older patients often experience a loss of independent physical functioning during the course of an acute illness requiring hospitalization. This functional decline is associated with serious sequelae including prolonged hospital stay, nursing home placement, and mortality. Elements of hospitalization may contribute to the progression or persistence of functional decline. The Unit for Acute Care of the Elderly (ACE Unit) at University Hospitals of Cleveland is an acute care general medical service that is designed to foster the independent functioning of patients. The Prehab Program of Patient Centered Care on the ACE Unit is a multifaceted intervention that integrates geriatric assessment into the optimal medical and nursing care of patients in an interdisciplinary environment. The Prehab Program has several key elements tailored to each individual patient's needs: a prepared environment, patient-centered care, multidimensional assessment and nonpharmacologic prescriptions, medical care review, and home planning. Standards of care serve to reduce the risk of iatrogenic illness resulting from polypharmacy, use of physical restraints, and diagnostic procedures. Nurse-initiated guidelines contribute to prevention of functional decline and to restoration of independent patient functioning. The effectiveness of the ACE Unit is being evaluated in a randomized clinical trial.

Abstract
OBJECTIVE To describe the evaluation of an interdisciplinary comprehensive geriatric assessment (CGA) consultation program for targeted hospitalized patients. DESIGN Multi-center randomized clinical trial (RCT) at four hospitals where patients were randomly assigned to CGA consultation or usual care by the attending physician, and a non-equivalent control group (NCG) at two hospitals. SETTING Six hospitals in a multi-specialty group practice model health maintenance organization (HMO). PARTICIPANTS 3593 patients age 65 years or older meeting at least one of 13 inclusionary criteria at admission. INTERVENTION Screening by hospital staff and standardized CGA consultation conducted by a nurse practitioner, social worker, and geriatrician at the four RCT hospitals. MAIN OUTCOME MEASURES Functional and health status, mortality, rehospitalization, and cost-effectiveness of the CGA program at 1 year post-randomization; validation of targeting (inclusionary) criteria that identify subgroups of patients deriving benefit from CGA; and physician contamination (learning from CGA and changing treatment provided to control patients). CONCLUSIONS A number of methodological issues need to be considered when conducting effectiveness trials of CGA. The concurrent design of a multi-center RCT, coupled with the NCG to determine physician contamination, is an innovative approach intended to determine more precisely the cost-effectiveness of CGA for frail hospitalized elderly persons. The large and heterogeneous patient population and the broad array of inclusionary criteria will permit the evaluation of the benefit of CGA for subgroups. All these features are intended to enhance the generalizability of study results.
