Emotional well-being of living kidney donors: findings from the RELIVE Study.

Following kidney donation, short-term quality of life outcomes compare favorably to US normative data but long-term effects on mood are not known. In the Renal and Lung Living Donors Evaluation Study (RELIVE), records from donations performed 1963-2005 were reviewed for depression and antidepressant use predonation. Postdonation, in a cross-sectional cohort design 2010-2012, donors completed the Patient Health Questionnaire (PHQ-9) depression screening instrument, the Life Orientation Test-Revised, 36-Item Short Form Health Survey and donation experience questions. Of 6909 eligible donors, 3470 were contacted and 2455 participated (71%). The percent with depressive symptoms (8%; PHQ-9>10) was similar to National Health and Nutrition Examination Survey participants (7%, p=0.30). Predonation psychiatric disorders were more common in unrelated than related donors (p=0.05). Postdonation predictors of depressive symptoms included nonwhite race OR=2.00, p=0.020), younger age at donation (OR=1.33 per 10 years, p=0.002), longer recovery time from donation (OR=1.74, p=0.0009), greater financial burden (OR=1.32, p=0.013) and feeling morally obligated to donate (OR=1.23, p=0.003). While cross-sectional prevalence of depression is comparable to population normative data, some factors identifiable around time of donation, including longer recovery, financial stressors, younger age and moral obligation to donate may identify donors more likely to develop future depression, providing an opportunity for intervention.

Poor sleep in organ transplant recipients: self-reports and actigraphy.

Solid organ transplant recipients are at increased risk of poor sleep due to pharmacotherapy and co-morbidities, but sleep problems are often unrecognized and untreated. Study aims were to measure rates of occurrence, characteristics, and correlates of poor sleep in recipients. The Pittsburgh Sleep Quality Index (PSQI) and sleep parameters measured by wrist actigraphy were obtained at baseline from 143 kidney, liver, heart, lung, or pancreas transplant recipients enrolled in a psychosocial intervention trial to improve symptoms and quality of life. Rates of poor sleep were determined using accepted clinical cutoffs; 41% (58 of 143) were poor sleepers (PSQI > 8) and 36% used sleep medications in the past month. Fifteen percent reported having obstructive sleep apnea (OSA) and 4% reported restless legs syndrome (RLS). Based on actigraphy (n = 73), 69% lacked sleep efficiency (SE), 32% took >30 min to fall asleep, 88% awakened during the night for more than 30 min, and 25% slept less than six h per night. Obesity and use of psychotropics or sleep medications, and pain were independent risk factors for poor objectively measured sleep. Poor sleep is an undertreated problem in transplantation. Screening for sleep problems and behavioral therapies with sleep hygiene instruction may benefit recipients.

Health-related quality of life in kidney donors from the last five decades: results from the RELIVE study.

Live donation benefits recipients, but the long-term consequences for donors remain uncertain. Renal and Lung Living Donors Evaluation Study surveyed kidney donors (N = 2455; 61% women; mean age 58, aged 24-94; mean time from donation 17 years, range 5-48 years) using the Short Form-36 Health Survey (SF-36). The 95% confidence intervals for White and African-American donors included or exceeded SF-36 norms. Over 80% of donors reported average or above average health for their age and sex (p < 0.0001). Donors' age-sex adjusted physical component summary (PCS) scores declined by half a point each decade after donation (p = 0.0027); there was no decline in mental component summary (MCS) scores. White donors' PCS scores were three points higher (p = 0.0004) than non-Whites'; this difference remained constant over time. Nine percent of donors had impaired health (PCS or MCS score >1 SD below norm). Obesity, history of psychiatric difficulties and non-White race were risk factors for impaired physical health; history of psychiatric difficulties was a risk factor for impaired mental health. Education, older donation age and a first-degree relation to the recipient were protective factors. One percent reported that donation affected their health very negatively. Enhanced predonation evaluation and counseling may be warranted, along with ongoing monitoring for overweight donors.

Steady-state carbamazepine pharmacokinetics following oral and stable-labeled intravenous administration in epilepsy patients: effects of race and sex.

Carbamazepine is a widely prescribed antiepileptic drug. Owing to the lack of an intravenous formulation, its absolute bioavailability, absolute clearance, and half-life in patients at steady state have not been determined. We developed an intravenous, stable-labeled (SL) formulation in order to characterize carbamazepine pharmacokinetics in patients. Ninety-two patients received a 100-mg infusion of SL-carbamazepine as part of their morning dose. Blood samples were collected up to 96 hours after drug administration. Plasma drug concentrations were measured with liquid chromatography-mass spectrometry, and concentration-time data were analyzed using a noncompartmental approach. Absolute clearance (l/hr/kg) was significantly lower in men (0.039 ± 0.017) than in women (0.049 ± 0.018; P = 0.007) and in African Americans (0.039 ± 0.017) when compared with Caucasians (0.048 ± 0.018; P = 0.019). Half-life was significantly longer in men than in women as well as in African Americans as compared with Caucasians. The absolute bioavailability was 0.78. Sex and racial differences in clearance may contribute to variable dosing requirements and clinical response.

Impact of lymphedema and arm symptoms on quality of life in breast cancer survivors.

Lymphedema is one of many arm problems reported by breast cancer survivors. Understanding the impact of lymphedema on quality of life requires consideration that arm symptoms may occur with or without lymphedema. It was hypothesized that specific arm symptoms and pain, related or unrelated to lymphedema, would be more associated with quality of life outcomes than arm swelling. The relation of arm swelling and of arm symptoms and associated severity with a range of quality of life outcomes following breast cancer treatment was assessed in a diverse sample of 295 women, 141 of whom had a clinical diagnosis of lymphedema. Arm swelling (as defined by interlimb volume or circumference differences) and lymphedema severity (defined by Common Toxicity Criteria) were less correlated with quality of life than total number of arm symptoms and specific individual symptoms. Pain in the affected arm correlated with poor quality of life outcomes, regardless of arm swelling. When evaluating the impact of lymphedema on quality of life, arm swelling may not be as important as the total number and specific types of arm symptoms present, as these may be more informative about quality of life outcomes in survivors of breast cancer with and without lymphedema.

Use of complementary therapies, adherence, and quality of life in lung transplant recipients.

PURPOSES: The purpose of this study was to describe complementary and alternative medicine (CAM) use by lung transplant patients and to determine whether CAM users differ from nonusers with respect to health status, quality of life, or medical adherence. METHODS: A mailed survey seeking CAM, quality of life, and adherence information was sent to 145 lung transplant recipients, and 99 responded. RESULTS: The majority (88%) used at least 1 form of CAM (median, 2; range, 0-17). Prayer (68%), support groups (43%), and relaxation techniques (31%) were the most common. Only 44% of users reported discussing CAM with their providers. CAM users were adherent to their transplant regimen. Few differences were found between CAM users and nonusers. Education, high symptom burden, female sex, and depression symptoms were associated with various types of CAM use. CONCLUSION: Most lung transplant recipients are using CAM. Providers must explore potential for interaction or enhancement between CAM and standard therapy to optimize care.

Promoting organ donation among high school students: an educational intervention.

OBJECTIVE: To evaluate the impact of a high school education program to promote organ donation awareness. The primary outcomes were intention to discuss organ donation with family or friends and actual discussion behavior. DESIGN: Longitudinal, observational study. METHODS: 665 high school students filled out evaluations at the beginning and at the end of a 1-hour education program. One month later, the students were asked to report whether they had discussed donation. RESULTS: After the program, knowledge and attitude scores and the proportion of students who intended to discuss donation increased (P < .05). At 1-month follow-up, 48% of students reported actual discussion. Intention has a strong, positive relationship with discussion behavior (odds ratio, 8.27; 95% CI, 3.18-21.51). Ethnicity, sex, and attitude of the students were also predictors of donation discussion behavior. CONCLUSIONS: This program appears to be effective in prompting discussion of organ donation among high school students.

Intensive care unit drug use and subsequent quality of life in acute lung injury patients.

OBJECTIVE: To examine the relationship between the use of sedative and neuromuscular blocking agents during a patient's intensive care unit (ICU) stay and subsequent measures of health-related quality of life. DESIGN: Cross-sectional mail survey and retrospective medical record abstraction of a prospectively identified cohort of lung injury patients. SETTING: ICUs in three teaching hospitals in a major metropolitan area. PATIENTS: Patients with acute lung injury (n = 24). INTERVENTIONS: None--observational study. MEASUREMENTS AND MAIN RESULTS: Patients' charts were reviewed for those patients returning postdischarge quality-of-life questionnaires. Duration, daily dose, and route of administration for sedatives and neuromuscular blocking agents were abstracted from ICU flow sheets. Relationships among ICU variables (days of sedation, days of neuromuscular blockade, and severity of illness as measured by Acute Physiology and Chronic Health Evaluation III score) and outcomes (symptoms of depression and symptoms of posttraumatic stress disorder) were assessed. Depressive symptoms at follow-up were correlated with days of sedation (p = .007), but not with days of neuromuscular blockade or initial severity of illness. The composite posttraumatic stress disorder symptom impact score was correlated with days of sedation (p = .006) and days of neuromuscular blockade (p = .035), but not with initial severity of illness. There were no significant differences between the frequency of patients reporting a specific posttraumatic stress disorder symptom in the high sedation group and the low sedation group, and there were no significant differences in specific posttraumatic stress disorder symptoms between the group that had received neuromuscular blockade and those who had not. CONCLUSIONS: The use of sedatives and neuromuscular blocking agents in the ICU is positively associated with subsequent measures of depression and posttraumatic stress disorder symptoms 6-41 months after ICU treatment for acute lung injury.

Value-added outcomes: the use of advanced practice nurses in long-term care facilities.

The purpose of this study was to determine the effect on clinical outcomes for newly admitted nursing home residents when advanced practice gerontological nurses (APNs) worked with staff to implement scientifically based protocols for incontinence, pressure ulcers, depression, and aggressive behavior. Use of APNs in this manner differs from the usual way APNs have been used in nursing homes, in which their primary focus has been to augment the physician's role. The APN treatment was randomly assigned to two nursing homes and usual care was assigned to a third. Trajectories from admission to 6 months revealed that residents with APN input into their care (n = 86) experienced significantly greater improvement or less decline in incontinence, pressure ulcers, and aggressive behavior, and they had higher mean composite trajectory scores compared with residents receiving usual care (n = 111). Significantly less deterioration in affect was noted in cognitively impaired residents in the treatment group. Findings suggest that APNs can be effective links between current scientific knowledge about clinical problems and nursing home staff.

Differences in family caregiver outcomes by their level of involvement in discharge planning.

Family caregivers play vital roles in assisting elders after they are released from the hospital. Although health care professionals advocate involving family caregivers in discharge planning for elders, little is known about the extent to which this involvement benefits or jeopardizes the caregiver's health and their perceptions of the caregiving experience. The purpose of this study was to determine whether the level of family caregiver involvement in discharge planning for an elder made a difference in caregiver health, discharge planning satisfaction, perception of care continuity, preparedness to assist the elder, and acceptance of the caregiving role 2 weeks and 2 months postdischarge. The sample consisted of 130 family caregivers for elders hospitalized with heart failure. Telephone interviews were conducted 2 weeks and 2 months postdischarge. The findings indicated that family caregivers who reported more involvement in discharge planning had significantly higher scores on satisfaction, feelings of preparedness, and perception of care continuity 2 weeks following the elder's hospitalization than those who reported little or no involvement in planning. Caregivers who reported more involvement in planning also were more accepting of the caregiving role. At 2 months postdischarge, caregivers who reported more involvement in discharge planning reported better health and more acceptance of the caregiving role than those who had little or no involvement in planning.

Development of a measure of resident satisfaction with the nursing home.

A satisfaction instrument specifically designed for use with nursing home residents, the Satisfaction with the Nursing Home Instrument (SNHI), was developed and tested with a sample of 110 nursing home residents from three proprietary facilities in Minnesota. As hypothesized, significant relationships were found between SNHI scores and measures of affect (negatively associated with depression and positively associated with morale), providing support for the construct validity of the scale. The lack of a significant relationship between SNHI scores and both age and mental status confirmed the predicted divergent validity of the instrument. The alpha coefficient for the 29-item scale was 0.81.

Predictors of elder and family caregiver satisfaction with discharge planning.

Client satisfaction is considered an important outcome measure in a managed care environment faced with escalating health care costs, shortened lengths of hospital stay, and competition among acute care hospitals. With shortened lengths of stay in acute care hospitals, discharge planning has assumed increased importance, particularly for elders who have chronic conditions, such as heart failure, that require follow-up care. Consequently, understanding the predictors of client satisfaction with discharge planning can help hospitals and their nursing staff to tailor services to meet client needs. Previous studies have focused on patient satisfaction with hospital care, with little attention given specifically to satisfaction with discharge planning and to family caregiver satisfaction with discharge planning. The purpose of this study was to determine whether there is a difference between elder and family member satisfaction with discharge planning 2 weeks after hospitalization and what factors predict satisfaction with discharge planning 2 weeks after hospitalization for elders hospitalized with heart failure and their family caregivers. Telephone interviews were conducted with 134 elder/family caregiver dyads 2 weeks after hospitalization. The results indicated that there were no statistically significant differences in discharge planning satisfaction of elders and their family caregivers. Continuity of care and extent to which they felt prepared to manage care following hospitalization were the best predictors of elder's and family caregiver's satisfaction with discharge planning.

A professional-patient partnership model of discharge planning with elders hospitalized with heart failure.

Despite efforts to improve the discharge planning process and subsequent outcomes, existing mechanisms fail to accurately identify elders' needs for follow-up care. Studies report rehospitalization rates ranging from 12 to 50%. The two aims of this study were to (1) examine the difference in outcomes for elders hospitalized with heart failure and caregivers who participated in a professional-patient partnership model of discharge planning compared to those who received the usual discharge planning and (2) examine differences in costs associated with hospital readmission and use of the emergency room following hospital discharge. A before-and-after nonequivalent control group design was used for this study. Data were collected from the control and the intervention cohorts before discharge and at 2 weeks and 2 months postdischarge. One hundred and fifty-eight patient-caregiver dyads completed both the predischarge and 2-weeks postdischarge interviews; 140 also completed a 2-month follow up. The average age of elders was 73.7 years; the average age of the caregivers was 58.5 years. The findings indicated that elders in the intervention cohort felt more prepared to manage care, reported more continuity of information about care management and services, felt they were in better health, and when readmitted spent fewer days in the hospital than the control cohort. Caregivers in the intervention cohort also reported receiving more information about care management and having a more positive reaction to caregiving 2 weeks postdischarge than the control cohort.

Impact of transplantation on quality of life in patients with diabetes and renal dysfunction.

BACKGROUND: Simultaneous pancreas/kidney transplant (SPK) is an effective therapy that enables people with insulin-dependent diabetes mellitus (IDDM) and renal failure to maintain a more normal lifestyle, without the burdens of dialysis and insulin therapy. However, SPK has been viewed as a higher cost and higher risk procedure than kidney transplant, and it is unclear if SPK offers better health and quality of life (QOL) outcomes than insulin therapy plus kidney transplant alone (KTA). The purpose of this study is to determine which procedure affords better health and QOL outcomes. METHODS: This is a prospective observational study with assessments at pretransplant and 1 and 3 years posttransplant. Patients with IDDM and renal dysfunction who received either SPK or KTA from August 1990 to September 1993 at a university transplant center were enrolled. A convenience sample of patients with IDDM and complications not seeking transplants were enrolled during the same time interval. The main outcome measures were the SF-36 Short Form Health Survey and a Satisfaction with Diabetes Therapy Scale. RESULTS: Most health status and QOL measures improved from baseline values within each transplant group. After adjustment for diabetes severity and other baseline variables, year 3 follow-up scores of the SPK cohort were better than those of the KTA cohort for several SF-36 scales: physical functioning (P=0.038); bodily pain (P=0.047), general health (P=0.014), and the physical component summary (P=0.003). SPK recipients also reported greater satisfaction with diabetes therapy (P=0.014) and perceived more benefits to secondary complications. The KTA patients, however, had higher adjusted scores for the role-emotional subscale (P=.037) and the mental component summary (P=.037). By year 3, the SPK cohort is at the 30th and 51st percentiles of the general adult US population in self-reported physical and mental health; the KTA cohort is at the 10th and 73rd percentile. CONCLUSIONS: At follow-up, both SPK and KTA patients report better health and quality of life but SPK patients report greater improvements than KTA patients in physical health and in areas that are diabetes specific. Although the improved physical outcomes of SPK patients are consistent with perceived benefits to secondary complications, the mental health differences cannot be explained by the study data and warrant further study.

Right heart catheterization in acute lung injury: an observational study.

Right heart catheterization (RHC) is commonly used in the diagnosis and management of acute lung injury (ALI). However, controversy exists regarding RHC. We examined RHC use during the first 3 d of ALI in an observational study of 135 patients defined by American-European Consensus Conference criteria. Study parameters examined for association with RHC included the Acute Physiology and Chronic Health Evaluation (APACHE) III score, lung injury score (LIS), and 20 additional epidemiologic, clinical, and laboratory parameters. RHC was performed in 70 patients (52%) within the first 3 d of ALI. RHC was positively associated (p < 0.05) with a diagnosis of sepsis, APACHE III score, blood urea nitrogen (BUN), creatinine, net fluid balance, and positive end-expiratory pressure. RHC was negatively associated (p < 0.05) with mean arterial pressure (Pa) and PaO2/FIO2. Logistic regression identified four predictors for RHC placement: sepsis, PaO2/FIO2, BUN, and Pa. Initial right atrial and pulmonary artery occlusion pressure measurements demonstrated a moderately strong correlation (r = 0.72). Use of RHC was associated with a change in one or more therapeutic interventions (intravascular fluids, vasopressors, diuretics) in 78% of patients. In summary, patients receiving RHC during the first 3 d of ALI were more severely ill than those who did not receive RHC, and RHC was associated with a change in therapy in most patients.

Quality of life before and after liver transplantation for cholestatic liver disease.

Liver transplantation (LT) is an established therapy for patients with end-stage primary biliary cirrhosis (PBC) or primary sclerosing cholangitis (PSC). In this report, we describe the health status and quality of life (QOL) in patients with these cholestatic liver diseases before and after LT. A QOL questionnaire was completed by 157 adult patients with PBC or PSC before and 1 year after liver transplantation at the Mayo Clinic or Baylor University Medical Center. This questionnaire measured four aspects of QOL, including symptoms; physical, social, and emotional functioning; health perceptions; and overall QOL. Changes in these QOL parameters before and after LT were described, and regression analysis was used to assess the relationships between clinical and QOL factors. There were no differences in QOL parameters between patients with PBC and PSC. QOL following transplantation was substantially better than before transplantation. This was observed in all four aspects of QOL. The degree of improvement as measured by effect size (difference in mean scores divided by the pretransplantation standard deviation) was 0.53 for symptoms (P <.01), 1.16 for function (P <.01), 2.37 for health satisfaction (P <.01), and 1.16 for overall QOL (P <.01). Patients' overall QOL before transplantation was significantly related to subjective and objective health status indicators and clinical factors such as ascites and renal dysfunction. QOL at 1-year follow-up, however, could not be adequately predicted by the pretransplantation subjective health status and clinical factors. Patients with end-stage cholestatic disease undergoing LT experience substantial improvement in all aspects of QOL addressed in this study. The patients' QOL 1 year after LT could not be predicted by pretransplantation variables used in this study.

Concentration-controlled zidovudine therapy.

BACKGROUND: Heterogeneity in the response to antiretroviral therapy has been attributed to pharmacologic, immunologic, and virologic differences between patients. Currently available antiretroviral agents used for the treatment of human immunodeficiency virus (HIV) infection in adults are administered in standard fixed doses. The active moiety of nucleoside anti-HIV drugs is the intracellular anabolite. Therefore the heterogeneity in response to nucleoside agents may arise as a result of pharmacologic variability at both the systemic and cellular level. OBJECTIVES: To determine whether a novel concentration-controlled zidovudine regimen could improve anti-HIV response compared with the standard fixed-dose approach. DESIGN: At the Outpatient Clinic of the General Clinical Research Center at the University of Minnesota, 20 persons with HIV infection received an oral regimen of zidovudine designed to achieve a target concentration in plasma of 0.7 mumol/L and the 500 mg/day standard dose in a randomized, crossover 24-week study. RESULTS: The concentration-controlled regimen achieved overall higher systemic concentrations with reduced interpatient variability: steady-state average zidovudine plasma concentrations were 0.76 mumol/L (coefficient of variation, 12%) versus 0.62 mumol/L (coefficient of variation, 32%) for the standard regimen. There was no difference in safety and tolerance between regimens. Intracellular zidovudine triphosphate concentrations averaged 160 fmol/10(6) peripheral blood mononuclear cells (PBMCs) with concentration-controlled versus 92 fmol/10(6) PBMCs for standard therapy. The percentage change from baseline in CD4 cells was a 22% increase for the concentration-controlled regimen versus a 7% decrease with standard therapy. CONCLUSIONS: These data indicate that pharmacologic variability affects antiretroviral response. Furthermore, these findings provide a framework to characterize the pharmacologic determinants of effect and quantitate their contribution to the heterogeneity in clinical response to optimize therapeutic benefit.

Interdisciplinary collaboration and discharge planning communication for elders.

The effects of personal characteristics and perceptions of interdisciplinary collaboration on discharge planning communication were examined for nurses, physicians, and social workers in two hospitals. The model for the study explained 61.7% of the variance in discharge planning communication for nurses. For all 142 health professionals, communication openness with social workers, problem solving between nurses and physicians, and collaboration with social workers were important to discharge planning communication. For nurses, communication satisfaction with patients and families also was important.

Quality of life after pancreas transplantation: a review.

For persons with diabetes and end stage renal disease, successful combined or sequential pancreas/kidney transplant is an attractive therapeutic alternative to insulin and dialysis. There is considerable controversy regarding pancreas transplantation (p Tx), however, as some recent reviews have concluded, p Tx results in at most only modest reductions in secondary complications and has increased morbidity and costs compared with kidney transplant alone. While the impact on patients' quality of life (QOL) is a major consideration for p Tx, the literature on this topic has not been carefully considered. The purpose of this review is to evaluate studies of QOL after p Tx and identify well-validated findings. Comparative cross-sectional and longitudinal studies have shown that the QOL outcomes of p Tx recipients who achieve insulin-independence are better than those of candidates or of recipients with pancreas graft loss. More positive health perceptions, improved social interaction and increased vitality/energy are significantly associated with successful p Tx. Researchers have found few areas where the QOL benefits of p Tx significantly exceed or differ from those that occur with kidney transplant alone. A consistent finding across studies is that p Tx improves patient perceptions about diabetes-specific issues such as satisfaction with diet flexibility and health management, while kidney transplant does not. Future studies should attempt to accrue sufficient sample sizes to permit statistical adjustment for selection biases; follow patients for several years to permit differences in rates of progression of secondary complications to impact QOL; and use current graft loss and morbidity statistics to estimate any added risks of p Tx over kidney-only transplant. It is still an open question as to whether or not there are sufficient QOL benefits from p Tx long-term to out-weigh added risks, and this needs to remain an active area of investigation.

Health-related quality of life after acute lung injury.

Our study objective was to assess health-related quality of life in survivors of acute lung injury (ALI) and to supplement generic and disease-specific questionnaires with findings from a focus group of ALI survivors. Six patients participated in the focus group, which revealed patient concerns with amnesia, depressed mood, avoidance behaviors, and a prolonged recovery period. Using a cross-sectional study design, 24 patients completed a questionnaire 6 to 41 mo after their lung injury. A total of 43% of the patients with ALI met criteria for depression; 43% had self-reported significant functional limitations, although 39% had minimal or no limitations. Significant respiratory and psychologic symptoms were reported in a quarter to a third of patients. There were large decrements in all domains of the SF-36 (a generic health-related quality-of-life instrument) in our sample compared with norms previously established for the general population. In addition, our patients had similar physical difficulties compared with previously studied patients with chronic medical illnesses but had more deficits in the social functioning and mental health domains. We conclude that long after lung injury, survivors have significantly lower health-related quality of life than the general population and are likely to have pulmonary and psychologic symptoms.
