Geriatric hospital medicine

Outpatient surgery postoperative ambulation and emergency department utilization

BACKGROUND

The ability to ambulate is an important indicator for wellness and quality of life. A major health event, such as a surgery, can derail this ability, and return to preoperative walking ability is a marker for recovery. Self-reported walking measurements by patients are subject to bias, thus wearable technology such as activity monitors have risen in popularity. We evaluated postoperative ambulation using an accelerometer in outpatient general surgery procedures with the hypothesis that those patients with less postoperative ambulation were at risk for adverse outcomes.

METHODS

A retrospective review of patients undergoing outpatient abdominal surgeries from November 2016 to July 2019 at a Veteran Affairs Medical Center. Patients wore an accelerometer preoperatively and postoperatively to measure their ambulation (steps/day). Outcome measures were 30-day readmissions and Emergency Department (ED) utilization. Postoperative ambulation was defined as daily percentages of their preoperative baseline. Patients without preoperative baseline data, > 3 missing days or any missing days prior to reaching baseline were excluded.

RESULTS

One-hundred-six patients underwent outpatient abdominal surgery. Twenty-two patients were excluded. Patients stratified into adult (18-64 years, 44 patients, 52%) and geriatric (≥ 65 years, 40 patients, 48%) cohorts. Geriatric patients were less likely to meet their preoperative baseline by postoperative day 7, 35% vs 61%, p = 0.016. Adult patients who failed to meet their preoperative baseline in first postoperative week had higher ED utilization; 4 (24%) vs 1 (4%), p = 0.04. Geriatric patients who failed to meet their baseline trended toward increased ED utilization; 5 (19%) vs. 1 (7%), p = 0.31.

CONCLUSION

Patients aged < 65 who fail to return to their preoperative daily step count within one week of outpatient abdominal surgery are 6× more likely to be seen in the ED. Postoperative ambulation may be able to predict ED utilization and recovery after outpatient surgery.

Early identification of patients at risk for delayed recovery of ambulation after elective abdominal surgery

BACKGROUND

Recovery of preoperative ambulation levels 1 month after surgery represents an important patient-centered outcome. The objective of this study is to identify clinical factors associated with the inability to regain baseline preoperative ambulation levels 28 days postoperatively.

METHODS

This is a prospective cohort study enrolling patients scheduled for elective inpatient abdominal operations. Daily ambulation (steps/day) was measured with a wristband accelerometer. Preoperative steps were recorded for at least 3 full calendar days before surgery. Postoperatively, daily steps were recorded for at least 28 days. The primary outcome was delayed recovery of ambulation, defined as inability to achieve 50% of preoperative baseline steps at 28 days postoperatively.

RESULTS

A total of 108 patients were included. Delayed recovery (< 50% of baseline preoperative steps/day) occurred in 32 (30%) patients. Clinical factors associated with delayed recovery after multivariable logistic regression included longer operative time (OR 1.37, 95% CI 1.05-1.79), open operative approach (OR 4.87, 95% CI 1.64-14.48) and percent recovery on POD3 (OR 0.73, 95% CI 0.56-0.96). In addition, patients with delayed ambulation recovery had increased rates of postoperative complications (16% vs 1%, p < 0.01) and readmission (28% vs 5%, p < 0.01).

CONCLUSION

After elective inpatient abdominal operations, nearly one in three patients do not recover 50% of their baseline preoperative steps 28 days postoperatively. Factors that can be used to identify these patients include longer operations, open operations and low ambulation levels on postoperative day #3. These data can be used to target rehabilitation efforts aimed at patients at greatest risk for poor ambulatory recovery.

Early mobility after fragility hip fracture: a mixed methods embedded case study

BACKGROUND

Following a hip fracture up to 60% of patients are unable to regain their pre-fracture level of mobility. For hospitalized older adults, the deconditioning effect of bedrest and functional decline has been identified as the most preventable cause of ambulation loss. Recent studies demonstrate that this older adult population spends greater than 80% of their time in bed during hospitalization, despite being ambulatory before their fracture. We do not fully understand why there continues to be such high rates of sedentary times, given that evidence demonstrates functional decline is preventable and early mobility recommendations have been available for over a decade.

METHODS

A descriptive mixed method embedded case study was selected to understand the phenomenon of early mobility after fragility hip fracture surgery. In this study, the main case was one post-operative unit with a history of recommendation implementation, and the embedded units were patients recovering from hip fracture repair. Data from multiple sources provided an understanding of mobility activity initiation and patient participation.

RESULTS

Activity monitor data from eighteen participants demonstrated a mean sedentary time of 23.18 h. Median upright time was 24 min, and median number of steps taken was 30. Qualitative interviews from healthcare providers and patients identified two main categories of themes; themes external to the person and themes unique to the person. We identified four factors that can influence mobility; a patient's pre-fracture functional status, cognitive status, medical unpredictability, and preconceived notions held by healthcare providers and patients.

CONCLUSIONS

There are multi-level factors that require consideration with implementation of best practice interventions, namely, systemic, healthcare provider related, and patient related. An increased risk of poor outcomes occurs with compounding multiple factors, such as a patient with low pre-fracture functional mobility, cognitive impairment, and a mismatch of expectations. The study reports several variables to be important considerations for facilitating early mobility. Communicating mobility expectations and addressing physical and psychological readiness are essential. Our findings can be used to develop meaningful healthcare provider and patient-centred interventions to address the risks of poor outcomes.

Assisted Walking Program on Walking Ability in In-Hospital Geriatric Patients: A Randomized Trial

OBJECTIVES

The main aim of this study was to evaluate if an individualized assisted walking program (IAWP) for hospitalized older patients could improve walking ability compared with usual geriatric care and rehabilitation.

DESIGN

A randomized controlled trial with an active control group, open labeled with parallel assignment was conducted between October 2018 and January 2020.

SETTING

Geriatric ward.

PARTICIPANTS

A total of 387 hospitalized patients (≥65 years) were randomly assigned to an intervention or control (usual-care) group.

INTERVENTION

The control group received usual hospital care. The intervention group received also an IAWP.

MEASUREMENTS

The primary endpoint was change in walking ability from hospital admission (considering both current and pre-admission status) to discharge, as assessed with the Braden Activity subscale measures. The secondary endpoint was the occurrence of in-hospital adverse events, such as complications of mobility, pressure ulcers, falls, pain and mortality, and the length of hospital stay. Intention-to-treat and per-protocol analyses were performed.

RESULTS

Baseline characteristics were similar between intervention and control groups. The intervention group, relative to the control group, had significantly improved walking ability at discharge (P < .001). There were no statistically significant differences between the groups in terms of in-hospital adverse events. No adverse effects were detected.

CONCLUSION

In in-hospital patients aged 65 and older, an IAWP improves walking ability at discharge.

A novel early mobility bundle improves length of stay and rates of readmission among hospitalized general medicine patients

Inpatient early mobility initiatives are effective therapeutic interventions for improving patient outcomes and decreasing use of hospital resources among adult ICU and general medicine patients. To establish and demonstrate guidelines for early patient ambulation, we developed and implemented a novel multidisciplinary mobility bundle utilizing the JH-HLM (Johns Hopkins Highest Level of Mobility) scale for mobility classification, on a single adult general medicine unit of a community hospital. Our results show that patients admitted to the unit after implementation of the mobility bundle had improved mobility scores, reduced rates of 30-day hospital readmission, and a shortened length of hospital stay. This study emphasizes the importance of measuring mobility using a systematic method, easing workflow among unit practitioners, and allowing mobility initiatives to be jointly driven by nursing, physical therapy, and physicians.

Perioperative Care Strategy for Older Adults

Geriatric patients are not just older adult patients. Aging brings about unique physiologic, psychological, and sociologic changes within individuals. Recognition of these unique characteristics and measuring for their impact; instituting mitigating strategies; using age-specific anesthetic measures; and performing a systematic, algorithmic care model in the postoperative period overseen by a multidisciplinary team brings about enhanced outcomes and improved quality of care for this expanding group of patients.

'I will walk out of here': Qualitative analysis of older rehabilitation patients' perceptions of mobility

OBJECTIVES

To understand the motivation of older rehabilitation inpatients for mobilisation, and identify barriers and enablers to greater mobilisation.

METHODS

Qualitative semi-structured interviews were conducted with older rehabilitation inpatients. All interviews were audio-taped, transcribed verbatim and analysed using thematic and inductive techniques.

RESULTS

From 23 interviews, we found that older patients strongly value mobilisation during rehabilitation admission, to get better and maintain identity, personhood and meaningful connections. At the patient level, mobilisation was impacted by patient's confidence, family support and symptom management. At the organisational level, barriers to mobilisation included lack of timely staff support, inflexible routines, limited social opportunities, lack of physical resources, and poor communication.

CONCLUSIONS

Recognising and understanding motivators, enablers and barriers to mobilising during subacute hospitalisation of older patients is an essential step towards developing and implementing successful strategies to promote greater mobilisation. Addressing mobilisation barriers requires a multifaceted approach at the patient and organisational level.

Low Rates of Survival Seen in Orthopedic Patients Receiving In-Hospital Cardiopulmonary Resuscitation

INTRODUCTION

Despite awareness of overall poor survival rates following cardiopulmonary resuscitation (CPR), some orthopedic patients with significant comorbidities continue to have inappropriate resuscitation plans. Furthermore, in certain injury groups such as patients with hip fractures, survival outcome data are very limited; current discussions regarding resuscitation plans may be inaccurate. This study assesses survival in orthopedic patients following CPR, to inform decision-making between physicians, surgeons, and patients.

METHODS

A dual center, retrospective cohort study was performed analyzing all orthopedic admissions that received CPR over a 25-month period, with a minimum of 1 year follow-up. National Cardiac Arrest Audit data, "mortality and morbidity" meeting records, National Hip Fracture Databases, and electronic notes were analyzed. Survival duration was measured, alongside reason for admission, location CPR occurred, and initial rhythm encountered.

RESULTS

Thirty-two patients received CPR over the 25-month period (median age: 83; range: 30-96). Three (9%) of 32 patients survived to discharge. Only 1 of the 26 patients older than 65 years survived to discharge. Fifteen (47%) of 32 had hip fractures, where 4 (27%) of 15 of this group survived 24 hours; none survived to discharge. When recorded, 22 (92%) of 24 initially had a nonshockable rhythm.

DISCUSSION

Cardiopulmonary resuscitation was conceptualized as a treatment for reversible cardiopulmonary causes. When used in trauma and orthopedic patients, especially older and/or hip fracture patients, it seldom led to hospital discharge. Different admission practices such as "front door" orthogeriatric reviews may explain the contrast in usage of CPR between the hospitals.

CONCLUSION

Survival rates following CPR were very low, with it proving specifically ineffective in hip fracture patients. Although every decision about resuscitation should be patient centered and individualized, this study will allow clinicians to be more realistic about outcomes from CPR, particularly in the hip fracture group.

Hospitalization-associated disability in older adults with valvular heart disease: incidence, risk factors and its association with care processes

BACKGROUND

The aim of this study was to determine the incidence and recovery of hospitalisation-associated disability (HAD), the associated risk factors, and the link with care processes in patients aged 70 years or older hospitalised with valvular heart disease (VHD).

METHODS

Prospective cohort study performed on the cardiology and cardiac surgery units of University Hospitals Leuven, Belgium. HAD was defined as the loss of independence to complete one of the Activities of Daily Living (ADLs) between hospital admission and discharge. Recovery of HAD at 30 days post hospital discharge was achieved when patients recovered their baseline ADL status (2 weeks before hospital admission) (ClinicalTrials.gov: NCT02572999).

RESULTS

Eighty patients were enrolled in the study, 77 completed the assessment at discharge and 62 responded at 30 days follow-up. Forty patients (51.9%) developed HAD; 18 of them (45.0%) recovered their baseline ADL status. The risk of HAD increased when patients were physically restrained (relative risk (RR) 1.73, 95% confidence interval (CI) 1.20-2.49), had indwelling catheters (RR 1.80, 95% CI 0.85-3.80) and received preventive pressure ulcer measures (RR 1.71, 95% CI 1.07-2.74). Patients with HAD had longer hospital stays (+3 days, p = .011) and longer use of indwelling catheters (+2 days, p = .024).

CONCLUSION

Half of the older adults with VHD developed HAD. The results indicate a potential association between HAD and care processes, which could be used as quality measures and intervention targets. Validation in larger cohort studies is recommended.

Language and understanding of cardiopulmonary resuscitation amongst an aged inpatient population

Greater patient involvement in health decision-making requires exchange of information between the patient and the healthcare professionals. Decisions regarding healthcare at the end of life include consideration of cardiopulmonary resuscitation (CPR). The stated objectives of this study were to determine how often language around concepts of resuscitation is used in the community by examination of the English language corpora (ELC); to explore the understanding of the same language by a group of older hospital patients; and to determine the patients' knowledge of the process and success of CPR, as well as the sources of their information. Medical inpatients aged 75 years and older were surveyed to this end in the setting of a tertiary university teaching hospital. Interrogation of the Australian, British and American English Corpora was accomplished by a linguist, and a questionnaire and semi-structured interview were administered to ascertain patient knowledge. We demonstrated that although medical inpatients have some familiarity with terms relating to resuscitation, there is a lack of understanding of the context, process and outcomes of CPR. The predominant sources of information were television and print media. Examination of the ELC revealed a paucity of the use of terms related to resuscitation. This finding indicates that physicians have a duty of care to determine patients' understanding around resuscitation language, and terms used, in discussions of their preferences before assuming their engagement in shared decision-making. More open public discussion around death and resuscitation would increase the general knowledge of the population and would provide a better foundation for the discussions in times of need.

Supervision of care networks for frail community dwelling adults aged 75 years and older: protocol of a mixed methods study

INTRODUCTION

The Dutch healthcare inspectorate (IGZ) supervises the quality and safety of healthcare in the Netherlands. Owing to the growing population of (community dwelling) older adults and changes in the Dutch healthcare system, the IGZ is exploring new methods to effectively supervise care networks that exist around frail older adults. The composition of these networks, where formal and informal care takes place, and the lack of guidelines and quality and risk indicators make supervision complicated in the current situation.

METHODS AND ANALYSIS

This study consists of four phases. The first phase identifies risks for community dwelling frail older adults in the existing literature. In the second phase, a qualitative pilot study will be conducted to assess the needs and wishes of the frail older adults concerning care and well-being, perception of risks, and the composition of their networks, collaboration and coordination between care providers involved in the network. In the third phase, questionnaires based on the results of phase II will be sent to a larger group of frail older adults (n=200) and their care providers. The results will describe the composition of their care networks and prioritise risks concerning community dwelling older adults. Also, it will provide input for the development of a new supervision framework by the IGZ. During phase IV, a second questionnaire will be sent to the participants of phase III to establish changes of perception in risks and possible changes in the care networks. The framework will be tested by the IGZ in pilots, and the researchers will evaluate these pilots and provide feedback to the IGZ.

ETHICS AND DISSEMINATION

The study protocol was approved by the Scientific Committee of the EMGO+institute and the Medical Ethical review committee of the VU University Medical Centre. Results will be presented in scientific articles and reports and at meetings.

Barriers to early mobility of hospitalized general medicine patients: survey development and results

OBJECTIVE

Functional status decline commonly accompanies hospitalization making patients vulnerable to complications. Such decline can be mitigated through hospital-based early mobility programs. Success in implementing patient mobility quality improvement processes requires evaluating providers' knowledge, attitudes, and behaviors.

DESIGN

A cross-sectional, self-administered survey in two different hospital settings was completed by 120 nurses and physical and occupational therapists (rehabilitation therapists, 38; nurses, 82) from six general medicine units. The survey was developed using published guidelines, literature review, and provider meetings and refined through pilot testing. Psychometric properties were assessed, and regression analyses were conducted to examine barriers to early mobility by hospital site, provider discipline, and years of experience.

RESULTS

Internal consistency reliability, item consistency, and discriminant validity psychometric characteristics were acceptable. In multivariable regression analysis, overall perceived barriers were similar between the two hospitals (P = 0.25) and significantly higher for staff with less experience (P = 0.02) and for nurses vs. rehabilitation therapists (P < 0.001).The survey identified specific barriers common to both nurses and rehabilitation therapists and other barriers that were discipline specific.

CONCLUSIONS

This novel survey identified important barriers to mobilizing medical inpatients that were similar across two hospital settings. These results can assist with the implementation of quality improvement projects for increasing early hospital-based patient mobility.

Uncertainty and alternate level of care: a narrative study of the older patient and family caregiver experience

Older adults in Canada who have multiple illnesses and are awaiting placement in long-term care are greatly impacted by alternate level of care (ALC). The purpose of this narrative study was to record the experiences of hospitalized older adults and their family caregivers after the patient is designated as requiring ALC. The researchers conducted 21 interviews with 5 older patients and 4 of their family caregivers. The interviews were transformed into stories summarizing the participants' experiences and analyzed for common themes. An overall finding was that uncertainty is integral to the experience of ALC as expressed under 3 themes: I never thought I'd end up like this, I don't know, and waiting. To improve the ALC experience, comprehensive strategies should be developed at the individual, organizational, and structural level to better manage uncertainty while seeking to reduce the occurrence of ALC among older patients.

Frequency and duration of nursing care related to older patient mobility

PURPOSE

To evaluate the frequency and duration of nursing care activity related to mobilizing older patients in acute care settings and determining who initiates the mobility event (patient or nurse).

METHODS

This was an observation study using time and motion. Observers shadowed 15 registered nurses (RNs) each for two to three 8-hr periods using hand-held computer tablets to collect data on frequency and duration of six mobility events (standing, transferring, walking to and from the patient bathroom, walking in the patient room, and walking in the hallway) that occurred in the nurse's presence. Chart reviews were conducted on 47 adult patients (> 65 years of age) who were cared for by the nurses during the observation periods. Descriptive statistics (mean, median, standard deviation, frequency, and proportion) were used to describe the occurrence of mobility events among all 47 patients and among a subgroup of 16 patients identified as dependent (needing human assistance of another to ambulate) at the time of admission.

RESULTS

Thirty-two percent of older patients were not engaged by an RN in any mobility event during an 8-hr period. For all patients, standing and transferring were the most frequent mobility activity. Mean duration for ambulation was less than 2 min per observation period. Patients who were dependent had fewer mobility events with no events related to ambulation initiated by nurses. The majority of mobility events were initiated by patients.

CONCLUSIONS

Nurses infrequently initiated mobility events for hospitalized older patients and most often engaged patients in low-level activity (standing and transferring).

CLINICAL RELEVANCE

Limited mobility (standing and transferring only) is an independent predictor of negative outcomes for hospitalized older patients. Nurses are in a key position to improve outcomes for hospitalized older patients by engaging them in mobility activity, particularly ambulation, but further research is needed to determine how best to engage nurses in these activities.

Attributing the responsibility for ambulating patients: a qualitative study

BACKGROUND

Functional decline has been identified as a leading negative outcome of hospitalization for older person. Functional decline is defined as a loss in ability to perform activities of daily living including a loss of independent ambulation. In the hospital literature, a patient's loss in ability to independently ambulate during the hospital stay varies between 15 and 59%. Lack of ambulation and deconditioning effects of bed rest are one of the most predictable causes of loss of independent ambulation in hospitalized older persons. Nurses have been identified as the professional most capable of promoting walking independence in the hospital setting. However, nurses do not routinely walk patients.

OBJECTIVE

The purpose of this study was to explore the relationship between nurses' attributions of responsibility for ambulating hospitalized patients and their decisions about whether to ambulate.

METHODS

A descriptive, secondary analysis of data gathered for a parent study was conducted. Grounded dimensional analysis was used to analyze the data. Participants consisted of 25 registered nurses employed on medical or surgical units from two urban hospitals in the United States.

RESULTS

Nurses fell into two groups: those who claimed ambulation of patients within their responsibility of practice and those who attributed the responsibility to another discipline. Nurses who claimed responsibility for ambulation focused on patient independence and psychosocial well-being. This resulted in actions related to collaborating with physical therapy, determining the appropriateness of activity orders, diminishing the risk and adjusting to resource availability. Nurses who attributed the responsibility deferred decisions about initiating ambulation to either physical therapy or medicine. This resulted in actions related to waiting, which involved, waiting for physical therapy clearance, physician orders, risks to decrease, and resources to improve before ambulating.

CONCLUSIONS

Nurses who claimed responsibility for ambulating patients within their domain of practice described actions that promoted patient independent function and were more likely to get patient s up to ambulate.

The added challenges of bone metastases treatment in elderly patients

Most cancers occur in those older than the age of 65 years. As the population of the world ages and life expectancies continue to increase, it is important to address treatment challenges for elderly patients. This narrative review details the challenges of palliative radiotherapy treatment for elderly patients with bone metastases. We begin with the definition of elderly and its appropriateness, outlining recent demographic data of patients with cancer. The current status of elderly participation in clinical trials is discussed by reviewing the recent literature and clinical trial data. Factors affecting enrolment of the elderly are assessed, with a focus on palliative radiotherapy trials, and what we can do to improve accrual in this data-driven setting. At present, there is a lack of level 1 evidence that evaluates the optimal treatment for elderly patients with bone metastases. Therefore, a review of safety and efficacy is given based on previously published reports. Palliative radiotherapy for elderly patients is a worthwhile treatment and should be recommended regardless of age, as supported by available evidence. Patient, family and physician concerns about physical burden may be reduced as single treatments (that often can be done in a single visit) are as beneficial as multiple treatments for painful bone metastases. In elderly patients, radiotherapy may even be the best treatment for these cases as opioid-related adverse events are amplified in this group and often dosages are more difficult to titrate. Clinicians should continue to encourage the enrolment of elderly patients on to clinical trials as these data form the basis of optimal treatment guidelines. Radiation oncologists are encouraged to reduce the physical burden for elderly patients by offering single treatments where appropriate and completing consultation, treatment simulation and treatment in a single clinical visit.

Integrated Services for Frail Elders (SIPA): A Trial of a Model for Canada

Le complexe formé par les maladies chroniques, les épisodes de maladies aiguës, les déficiences physiologiques, les incapacités fonctionnelles et les problèmes cognitifs dominent les personnes âgées fragiles. Elles comptent sur l'aide des programmes sociaux et de Santé qui, au Canada, sont encore fragmentés. Le SIPA (Services intégrés pour les personnes âgées fragiles) est un modèle de services intégrés basé sur des services de proximité, une équipe multidisciplinaire et un gestionnaire de cas qui détiennent la responsabilité clinique de l'ensemble des services sociaux et de Santé requis, la capacité de mobiliser des ressources en fonction des besoins et l'application de protocole de soins. Le projet de démonstration SIPA a utilisé un devis expérimental avec assignation aléatoire de 1230 participants, de deux quartiers de Montréal, dans un groupe expérimental et un groupe témoin. Les coûts des services institutionnels ont été de 4270$; inférieur dans le SIPA comparés au groupe témoin, les coûts des services de proximité ont été supérieurs de 3394$;. La proportion des personnes en attente d'hébergement en hôpitaux de courte durée a été deux fois plus élevée dans le groupe témoin que dans le groupe SIPA. Les coûts des hospitalisations de courte durée des personnes du SIPA avec incapacité dans les activités de la vie quotidienne ont été inférieurs d'au moins 4000$; à ceux des personnes du groupe témoin. En conclusion, l'expérimentation SIPA démontre qu'il est possible de s'engager dans des projets de démonstration ambitieux et rigoureux au Canada. Ces résultats ont été obtenus sans augmentation des coûts globaux des services sociaux et de santé, sans diminution de la Qualité des soins et sans augmentation du fardeau des personnes âgées et de leurs proches.

Des services intégrés pour les personnes âgées fragiles (SIPA): expérimentation d'un modèle pour le Canada

The complex formed by chronic illness, episodes of acute illness, physiological disabilities, functional limitations, and cognitive problems is prevalent among frail elderly persons. These individuals rely on assistance from social and health care programs, which in Canada are still fragmented. SIPA (Services intégrés pour les personnes âgées fragiles) is an integrated service model based on community services, a multidisciplinary team, case management that retains clinical responsibility for all the health and social services required, and the capacity to mobilize resources as required and according to the care protocol. The SIPA demonstration project used an experimental design, with random allocation of the 1,230 participants from two areas of Montreal to an experimental and a control group. The costs of institutional services were $4,270 less for those in the SIPA group compared to the control group; the costs of community care were $3,394 more. The proportion of persons waiting in acute care hospitals for nursing home placement was twice as high in the control group as in the SIPA group. The costs of acute hospitalizations for persons in the SIPA group with ADL disabilities were at least $4,000 lower than those for persons in the control group. In conclusion, the SIPA trial showed that it is possible to undertake ambitious and rigorous demonstration projects in Canada. These results were obtained without an increase in the overall costs of health and social services, without reducing the quality of care, and without increasing the burden on elderly persons and their relatives.

Cascade iatrogenesis: factors leading to the development of adverse events in hospitalized older adults

Older adults are at particular risk for injuries associated with hospitalization and the rate of adverse events increases significantly with age. The purpose of this paper is to review factors associated with the development of adverse events in hospitalized older adults, especially those factors that contribute to cascade iatrogenesis. Cascade iatrogenesis is the serial development of multiple medical complications that can be set in motion by a seemingly innocuous first event [Rothschild, J.M., Bates, D.W., Leape, L.L., 2000. Preventable medical injuries in older patients. Archieves of Internal Medicine 160 (October), 2717-2728]. Research has examined how patient characteristics may lead to cascade iatrogenesis, but existing conceptual models and research have not considered the role of nursing care. Using the outcome postoperative respiratory failure as an example, we expand on existing knowledge about factors associated with older adults' risk for developing this complication by presenting a conceptual model of events that may trigger the initial cascade and the nursing care variables that may prevent or mitigate these risks. We believe that this model will help guide research in this area and enable clinicians to identify systemic failures and develop targeted interventions to prevent their occurrence.

Predictors of regaining ambulatory ability during hospitalization

BACKGROUND

Loss of ambulatory ability with acute hospitalization is common and often does not improve by discharge.

OBJECTIVES

To define admission predictors of regaining ambulatory ability during hospitalization in patients with expected activity limitations.

DESIGN

Prospective cohort study.

SETTING

University teaching hospital.

PARTICIPANTS

Two hundred and eighty-six patients at least 55 years of age whose activity was expected to be limited to a bed or chair for at least the first 5 days of hospitalization or who had a hip fracture, who were ambulatory in the 4 weeks prior to hospital admission, and whose length of stay in the hospital was less than 32 days.

MEASUREMENTS

Baseline data collected from admission physician and nurse interviews and abstracted from the medical records included length of stay, demographic characteristics, global health measures, presence of specific diseases, and hospital-related factors hypothesized to affect ambulation. Nurses were asked weekly if patient activity was still expected to be limited to a bed or chair.

RESULTS

Despite initially being limited to a bed or chair, 42% had regained ambulatory ability by discharge. Recovery of ambulatory ability was independently associated with not being married (odds ratio [OR] = 3.0, 95% confidence interval [CI] 1.4-6.2), higher physician-rated life expectancy (OR = 1.9, 95% CI 1.3-2.8), absence of restraints (OR = 2.5, 95% CI 1.2-5.5), having a urinary catheter (OR = 2.2, 95% CI 1.2-5.5), having deep vein thrombosis (OR = 11.4, 95% CI 1.2-105.1), and having a higher level of bed mobility at admission (OR = 1.7, 95% CI 1.1-2.6).

CONCLUSIONS

Recovery of ambulatory ability is closely associated with physician-rated life expectancy and hospital-related factors, particularly those that affect mobility. Early recognition of who will recover ambulatory ability may help with discharge planning and potential interventions.

A system of integrated care for older persons with disabilities in Canada: results from a randomized controlled trial

BACKGROUND

Care for elderly persons with disabilities is usually characterized by fragmentation, often leading to more intrusive and expensive forms of care such as hospitalization and institutionalization. There has been increasing interest in the ability of integrated models to improve health, satisfaction, and service utilization outcomes.

METHODS

A program of integrated care for vulnerable community-dwelling elderly persons (SIPA [French acronym for System of Integrated Care for Older Persons]) was compared to usual care with a randomized control trial. SIPA offered community-based care with local agencies responsible for the full range and coordination of community and institutional (acute and long-term) health and social services. Primary outcomes were utilization and public costs of institutional and community care. Secondary outcomes included health status, satisfaction with care, caregiver burden, and out-of-pocket expenses.

RESULTS

Accessibility was increased for health and social home care with increased intensification of home health care. There was a 50% reduction in hospital alternate level inpatient stays ("bed blockers") but no significant differences in utilization and costs of emergency department, hospital acute inpatient, and nursing home stays. For all study participants, average community costs per person were C dollar 3390 higher in the SIPA group but institutional costs were C dollar 3770 lower with, as hypothesized, no difference in total overall costs per person in the two groups. Satisfaction was increased for SIPA caregivers with no increase in caregiver burden or out-of-pocket costs. As expected, there was no difference in health outcomes.

CONCLUSIONS

Integrated systems appear to be feasible and have the potential to reduce hospital and nursing home utilization without increasing costs.

Resuscitation of the Elderly

The changing demographics of America's population over the past couple of decades have propelled geriatric medicine into the fore-front. Due to this, emergency medicine physicians will face numerous challenges managing an increasing number of critically ill elderly patients. This article will focus on success of resuscitation in this population, important pathophysiologic changes that occur with aging, as well as ethical considerations in end-of-life care.

Systematic review of barriers to the recruitment of older patients with cancer onto clinical trials

PURPOSE

Older patients are significantly underrepresented in cancer clinical trials. A literature review was undertaken to identify the barriers that impede the accrual of this vulnerable population onto clinical trials and to determine what specific strategies are needed to improve the representation of older patients in research studies.

METHODS

A systematic literature search was undertaken using several different strategies to identify relevant articles.

RESULTS

Nine of 31 relevant papers from 159 citations were included. Age is a significant barrier to recruitment; only a quarter to one third of potentially eligible older patients are enrolled onto trials. Physicians' perceptions, protocol eligibility criteria with restrictions on comorbid conditions, and functional status to optimize treatment tolerability are the most important reasons resulting in the exclusion of older patients. Other barriers include the lack of social support and the need for extra time and resources to enroll these patients. Conversely, older patients do not view their age as an important reason for refusing trials.

CONCLUSION

Specific clinical trials confined to older patients should be conducted to evaluate tumor biology, treatment tolerability, and the effect of comorbid conditions. Protocol designs need to stratify for age and be less restrictive with respect to exclusions on functional status, comorbidity, and previous cancers, such that results are generalizable to older patients. Physician education to dispel unfounded perceptions, improved access to available clinical trials, and provision of personnel and resources to accommodate the unique requirements of an older population are possible solutions to remove the barriers of ageism.
