Delirium in hospitalized older patients

Delirium is a common, serious problem for hospitalized older patients. Recognition of delirium poses challenges requiring cognitive assessment and knowledge of the clinical course. Delirium often is of multiple causes and is associated with a poor long-term prognosis. Nonpharmacologic approaches for delirium management are recommended; pharmacologic management should be reserved for patients who pose a danger to themselves or others. Importantly, delirium and its complications may be preventable through a targeted risk factor approach.     

Delirium in hospitalized older patients: recognition and risk factors

Delirium, or acute confusional state, represents a common, serious, potentially preventable and increasing problem for older hospitalized patients. This study is intended to improve overall understanding of the problem of delirium and thus to lessen its adverse impact on the older population. The specific aims of this study are (1) to examine the epidemiology of delirium in older patients; (2) to evaluate barriers to recognition; (3) to present the Confusion Assessment Method (CAM) simplified algorithm to improve recognition; (4) to elucidate predisposing and precipitating factors for delirium; and (5) to propose preventive strategies. Delirium occurs in 10-60% of the older hospitalized population and is unrecognized in 32-66% of cases. The CAM algorithm provides a sensitive (94-100%), specific (90-95%), reliable, and easy to use means for identification of delirium. Four predisposing and five precipitating factors were identified and validated to identify patients at high risk for development of delirium. Primary prevention of delirium should address important delirium risk factors and target patients at intermediate to high risk for delirium at admission.     

Importance of functional measures in predicting mortality among older hospitalized patients

CONTEXT: Measures of physical and cognitive function are strong prognostic predictors of hospital outcomes for older persons, but current risk adjustment and burden of illness assessment indices do not include these measures. OBJECTIVE: To evaluate and validate the contribution of functional measures to the ability of 5 standard burden of illness indices (Charlson, Acute Physiology and Chronic Health Evaluation [APACHE] II, Disease Staging, All Patient Refined Diagnosis Related Groups, and a clinician's subjective rating) in predicting 90-day and 2-year mortality among older hospitalized patients. DESIGN: Two prospective cohort studies. SETTING: General medicine service, university teaching hospital. PATIENTS: For the development cohort, 207 consecutive patients aged 70 years or older, and for the validation cohort, 318 comparable patients. MAIN OUTCOME MEASURE: Death within 90 days and 2 years from the index admission. RESULTS: In the development cohort, 29 patients (14%) and 81 patients (39%) died within 90 days and 2 years, respectively. A functional axis was developed using 3 independent risk factors: impairment in instrumental activities of daily living, Mini-Mental State Examination score of less than 20, and shortened Geriatric Depression Scale score of 7 or higher, creating low-, intermediate-, and high-risk groups with associated mortality rates of 20%, 32%, and 60%, respectively (P<.001); the C statistic for the final model was 0.69. The corresponding mortality rates in the validation cohort, in which 59 (19%) and 138 (43%) died within 90 days and 2 years, respectively, were 24%, 45%, and 60% (P<.001); the C statistic for the final model was 0.66. For each burden of illness index, the functional axis contributed significantly to the predictive ability of the model for both 90 days and 2 years. When the functional axis and each burden of illness measure were analyzed in cross-stratified format, mortality rates increased progressively from low-risk to high-risk functional groups within strata of burden of illness indices (double-gradient phenomenon). The contributions of functional and burden of illness measures were substantive and interrelated. CONCLUSIONS: Functional measures are strong predictors of 90-day and 2-year mortality after hospitalization. Furthermore, these measures contribute substantially to the prognostic ability of 5 burden of illness indices. Optimal risk adjustment for older hospitalized patients should incorporate functional status variables.     

Identifying hospitalized older patients at varying risk for physical performance decline: a new approach

It is not known how immaturity and disease influence postnatal thyroid function in infants <30 wk of gestational age. We performed serial measurements of plasma thyroxine (T4), free T4 (FT4), triiodothyronine (T3), reverse T3 (rT3), TSH, and T4-binding globulin (TBG) in 100 infants of <30 wk of gestation, during the first 8 postnatal weeks, to investigate the influences of disease and gestational age on the time course of thyroid hormones. One hundred infants were divided twice into two groups: 1) in a group of 25-28 and of 28-30 wk of gestation; and 2) in a sick and a healthy group, with similar gestational ages. The time course of T4, FT4, T3, TSH, and TBG, but not rT3 differed significantly (p < 0.005) between the gestational age groups. T4 and FT4 decreased to levels below the cord blood value with a deeper FT4 nadir on d 7 in the youngest group. Disease decreased T4, FT4, T3, TSH, and TBG concentrations especially during the 1st wk after birth (p < 0.005). However, the FT4 nadir on d 7 was similar in sick and healthy infants. After 3 wk, T4, FT4, T3, and TBG were higher in the sick group compared with the healthy group. rT3 levels were not increased in sick infants. We conclude that the extent of the FT4 decrease after birth in infants of <30 wk gestation is mainly influenced by gestational age and probably reflects a transient depletion of thyroidal hormone reserves. rT3 cannot be used as a marker of nonthyroidal illness in very preterm infants.     

Subjective versus objective sleep in Vietnam combat veterans hospitalized for PTSD

Twenty-five Vietnam combat veterans with chronic severe posttraumatic stress disorder (PTSD) completed a sleep self-report questionnaire on admission to an inpatient treatment program. Between 1 and 2 months later each spent 3 or more nights in the sleep laboratory. When self-report and laboratory findings were compared, significant relationships were observed between sleep schedule items such as time-to-bed/time-out-of-bed and polysomnographic measures of sleep. In contrast, global ratings of sleep quality were generally unrelated to polysomnographic measures. These findings may have implications for survey research assessing sleep quality in traumatized populations.     

Assessment and treatment of sleep disorders in older adults: A review for rehabilitation psychologists.

Recent research has led to significant progress in the assessment and treatment of sleep disturbance in older adults. Similar advances have been made with sleep disorders secondary to age-related chronic illness. The assessment and treatment of sleep disorders encompasses numerous behavioral aspects. Thus, rehabilitation psychologists are ideally positioned to help apply these new advances to the growing number of older adult patients in the rehabilitation setting. The authors provide an overview of age and disease-related sleep disorders. They provide details for implementation of behavioral treatments for geriatric insomnia that is comorbid with chronic illness. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Therapists' expectations for in-therapy roles of hospitalized patients

Therapists' expectations with regard to in-therapy behavior of hospitalized patients were measured and factor analyzed. Five interpretable factors emerged and supported the conclusion that therapists' role expectations for patients complement patients' role expectations for therapists. Mean scores on the factors were independent of therapists' experience and professional training.     

Risk factors for falls of hospitalized stroke patients

BACKGROUND AND PURPOSE: Patients with stroke are at a high risk for falling. We assessed the fall incidence and risk factors for patients hospitalized as the result of an acute stroke. METHODS: We studied a cohort of 720 stroke patients from 23 hospitals in The Netherlands. The data were abstracted from the medical and nursing records. RESULTS: We studied 346 women and 374 men with a median age of 75 years; 77% of the patients had had a cerebral infarct, 17% had had a hemorrhage, and 6% had had an undefined stroke. We recorded 104 patients (14%) who fell at least once; there were a total of 173 falls. The incidence of falls was 8.9/1000 patients per day. The daily incidence was 6.2/1000 patients for first falls and 17.9/1000 patients for second falls. Heart disease (relative risk [RR], 1.6; 95% confidence interval [CI], 1.0 to 2.4), mental decline (RR, 1.6; 95% CI, 1.0 to 2.4), and urinary incontinence (RR, 2.3; 95% CI, 1.3 to 4.1) were incremental risk factors for first falls, whereas the use of major psychotropic drugs lowered the fall risk (RR, 0.5; 95% CI, 0.3 to 0.8). The fall RR for patients with one previous fall was 2.2 (95% CI, 1.5 to 3.2), adjusted for the other risk factors. Most falls occurred during the day. Approximately 25% of the falls caused slight-to-severe injury, whereas three falls (2%) led to hip fractures. CONCLUSIONS: Stroke patients have at risk of falling. The identification of patients at risk may be a first step toward the implementation of fall-prevention measures for these patients.     

Communication problems for patients hospitalized with chest pain

In many settings, primary care physicians have begun to delegate inpatient care to hospitalists, but the impact of this change on patients' hospital experience is unknown. To determine the effect on physician-patient communication of having the regular outpatient physician (continuity physician) continue involvement in hospital care, we surveyed 1,059 consecutive patients hospitalized with chest pain. Patients whose continuity physicians remained involved in their hospital care were less likely to report communication problems regarding tests (20% vs 31%, p =.03), activity after discharge (42% vs 51%, p =.02), and health habits (31% vs 38%, p =. 07). In a setting without a designated hospitalist system, communication problems were less frequent among patients whose continuity physicians were involved in their hospital care. New models of inpatient care delivery can maintain patient satisfaction but to do so must focus attention on improving physician-patient communication.     

An assessment tool for older patients

A full and detailed assessment of older patients should include social circumstances. An assessment should identify problems of functional activity and use screening tools to aid referral to specialist multidisciplinary staff.     

Religious coping and health status in medically ill hospitalized older adults

Associations between specific religious coping (RC) behaviors and health status in medically ill hospitalized older patients were examined and compared with associations between nonreligious coping (NRC) behaviors and health status. The sample consisted of 577 patients age 55 or over consecutively admitted to the general medical inpatient services of Duke University Medical Center (78%) or the Durham VA Medical Center (22%). Information was gathered on 21 types of RC, 11 types of NRC, and 3 global indicators of religious activity (GIRA). Health measures included multiple domains of physical health, depressive symptoms, quality of life, stress-related growth, cooperativeness, and spiritual growth. Demographic factors, education, and admitting hospital were control variables. "Negative" and "positive" types of religious coping were identified. Negative RC behaviors related to poorer physical health, worse quality of life, and greater depression were reappraisals of God as punishing, reappraisals involving demonic forces, pleading for direct intercession, and expression of spiritual discontent. Coping that was self-directed (excluding God's help) or involved expressions reflecting negative attitudes toward God, clergy, or church members were also related to greater depression and poorer quality of life. Positive RC behaviors related to better mental health were reappraisal of God as benevolent, collaboration with God, seeking a connection with God, seeking support from clergy/church members, and giving religious help to others. Of 21 RC behaviors, 16 were positively related to stress-related growth, 15 were related to greater cooperativeness, and 16 were related to greater spiritual growth. These relationships were both more frequent and stronger than those found for NRC behaviors. Certain types of RC are more strongly related to better health status than other RC types. Associations between RC behaviors and mental health status are at least as strong, if not stronger, than those observed with NRC behaviors.     

Renal transplantation for patients 60 years of older. A single-institution experience

OBJECTIVE: The authors reviewed renal transplant outcomes in recipients 60 years of age or older. BACKGROUND: Before cyclosporine, patients older than 45 years of age were considered to be at high risk for transplantation. With cyclosporine, the age limits for transplantation have expanded. METHODS: The authors compared patient and graft survival, hospital stay, the incidence of rejection and rehospitalization, and the cause of graft loss for primary kidney recipients 60 years of age or older versus those 18 to 59 years of age. For those patients > or = 60 years transplanted since 1985, the authors analyzed pretransplant extrarenal disease and its impact on post-transplant outcome. In addition, all surviving recipients > or = 60 years completed a medical outcome survey (SF-36). RESULTS: Patient and graft survival for those > or = 60 years of age versus those 18 to 59 years of age were similar 3 years after transplant. Subsequently, mortality increased for the older recipients. Death-censored graft survival was identical in the two groups. There were no differences in the cause of graft loss. Those 60 years of age or older had a longer initial hospitalization, but had fewer rejection episodes and fewer rehospitalizations. Quality of life for recipients 60 years of age or older was similar to the age-matched U.S. population. CONCLUSION: Renal transplantation is successful for recipients 60 years of age or older. Most of them had extrarenal disease at the time of transplantation; however, extrarenal disease was not an important predictor of outcome and should not be used as an exclusion criterion. Post-transplant quality of life is excellent.     

A call for psychotherapy integration in work with older adult patients.

Although a growing number of studies in the literature espouse the effectiveness of various therapies with elderly adults (e.g., cognitive-behavioral, reminiscence, and interpersonal therapies), little has been written about the perceived need for psychotherapy integration in clinical geropsychology. This article argues that an assimilative, integrative approach allows a practitioner to maintain a conceptual framework in one theoretical orientation while matching techniques from other orientations to elderly patients' unique situations or needs. Older adults represent a more heterogeneous group than both young and middle-aged adults, and therapists must often address special issues related to aging, such as chronic illness and social stigma. Integrative work with older adults also appears unique because interventions must often focus on the impact of the patient's immediate environment and outside systems, such as families and institutions, as well as the traditional therapist patient relationship. A case study is offered to illustrate the effective use of psychotherapy integration with an older adult in treatment. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Depression and physical disability outcomes in depressed medically ill hospitalized older adults

The authors examined depression/disability outcomes in hospitalized older medical patients during the year after hospital discharge to assess the pattern and rate of changing depression and disability, the causal relationship between these variables, and to identify patients at greatest risk for poor outcomes. A group of 119 medical patients at Duke Hospital were both depressed and disabled; they were followed for a median of 47 weeks after hospital discharge. Time-series analyses showed that depression and disability tended to track together, and most changes occurred within the first 6 months after discharge. Blacks were more likely to remit from depression despite continued disability and less likely to experience continued depression despite decreased disability. Patients with a history of depression were less likely to experience improvement in depression unless disability improved. Number of medical diagnoses and depression severity independently predicted poorer depression outcomes. Certain characteristics of patients during hospitalization predict depression/disability outcomes after discharge.
