Use of Health-Related, Quality-of-Life Metrics to Predict Mortality and Hospitalizations in Community-Dwelling Seniors

Patient-reported geriatric symptoms as risk factors for hospitalization and emergency department visits

There is an urgent need to identify predictors of adverse outcomes and increased health care utilization in the elderly. The Mayo Ambulatory Geriatric Evaluation (MAGE) is a symptom questionnaire that was completed by patients aged 65 years and older during office visits to Primary Care Internal Medicine at Mayo Clinic in Rochester, MN. It was introduced to improve screening for geriatric conditions. We conducted this study to explore the relationship between self-reported geriatric symptoms and hospitalization and emergency department (ED) visits within 1 year of completing the survey. This was a retrospective cohort study of patients who completed the MAGE from April 2008 to December 2010. The primary outcome was an ED visit or hospitalization within 1 year. Predictors included responses to individual questions in the MAGE. Data were obtained from the electronic medical record and administrative records. Logistic regression analyses were performed from significant univariate factors to determine predictors in a multivariable setting. A weighted scoring system was created based upon the odds ratios derived from a bootstrap process. The sensitivity, specificity, and AUC were calculated using this scoring system. The MAGE survey was completed by 7738 patients. The average age was 76.2 ± 7.68 years and 57% were women. Advanced age, a self-report of worse health, history of 2 or more falls, weight loss, and depressed mood were significantly associated with hospitalization or ED visits within 1 year. A score equal to or greater than 2 had a sensitivity of 0.74 and specificity of 0.45. The calculated AUC was 0.60. The MAGE questionnaire, which was completed by patients at an outpatient visit to screen for common geriatric issues, could also be used to assess risk for ED visits and hospitalization within 1 year.

When do patient-reported outcome measures inform readmission risk?

OBJECTIVE

To characterize changes in patient-reported outcome measures from hospital discharge to assess when they best inform risk of utilization as defined by readmissions or emergency department use.

PARTICIPANTS

Patients discharged from an urban safety-net hospital.

DESIGN

Longitudinal cohort study.

MAIN MEASURES

We serially administered the Memorial Symptom Assessment Scale (MSAS) and the PROMIS Global Health short form assessing General Self-Rated Health (GSRH), Global Physical (GPH), and Mental (GMH) Health at 0, 30, 90, and 180 days from hospital discharge. Time to first utilization from each survey was plotted by dichotomizing our sample on each patient-reported measure, and equivalence of the time-to-event curves was assessed using the log-rank test. Cox proportional hazard models were used to control for available covariates including prior utilization during the study, Charlson score, age, gender, and race/ethnicity. We assessed each measure's effect on the fit of the predictive models using the likelihood ratio test.

KEY RESULTS

We recruited 196 patients, of whom 100%, 98%, 90%, and 88% completed each respective survey wave. Participants' mean age was 52 years, 51% were women, 60% were non-Hispanic black, and 21% completed the questionnaires in Spanish. In-hospital assessments revealed high symptom burden and poor health status. In-hospital assessments of GMH and GSRH predicted 14-day reutilization, whereas posthospitalization assessments of MSAS and GPH predicted subsequent utilizations. Each measure selectively improved predictive model fit.

CONCLUSIONS

Routine measurement of patient-reported outcomes can help identify patients at higher risk for utilizations. At different time points, MSAS, GPH, GMH, and GSRH all informed utilization risk.

Employment as a Social Determinant of Health: A Systematic Review of Longitudinal Studies Exploring the Relationship Between Employment Status and Physical Health

Purpose:To explore employment as a social determinant of health through examining the relationship between employment status and physical health.

Method:The authors explored the causal relationship between employment status and physical health through conducting a systematic review of 22 longitudinal studies conducted in Finland, France, the Netherlands, Nigeria, Sweden, United Kingdom, and the United States.

Results:Five common trajectories were identified as employment, unemployment, job loss, reemployment, and retired. Unemployment and job loss were associated with poorer physical health. Employment and reemployment were associated with better physical health.

Conclusion:To enhance employment outcomes, it is important for service providers to acknowledge the interaction between the client’s physical health and employment status, and assess client physical functioning. Additional research is necessary to further elucidate this interaction.

Association between physical and mental health-related quality of life and adverse outcomes; a retrospective cohort study of 5,272 Scottish adults

Background

Health-related quality of life (HRQoL) is associated with adverse outcomes in disease-specific populations. This study examines whether it is also independent predictor of incident cancer, coronary heart disease (CHD) and mortality in the general population.

Methods

The records of adult participants in the Scottish Health Survey 2003 were linked with hospital admissions, cancer registrations and death certificates. Cox proportional hazard models were used to explore the associations between quintiles of physical and mental component summary score (PCS and MCS respectively) of the SF-12 and adverse outcomes. Higher quintiles of both PCS and MCS indicate better health status.

Results

Among the 5,272 study participants, the mean PCS score was 49 (standard deviation (SD) 10.3). Participants were followed-up for a mean of 7.6 years. On survival analysis the lowest quintile of PCS was a strong predictor of all-cause death (hazard ratio (HR) 2.81, 95% CI 1.76, 4.49), incident cancer (HR 1.63, 95% CI 1.10, 2.42), and CHD events (HR 1.99, 95% CI 1.00, 3.96), compared to the highest quintile. This association was independent of adiposity and other confounders. The mean MCS score 52 (SD 8.8). MCS quintile was not associated with incident cancer and CHD, and the association between MCS and all-cause death (HR 1.33, 95% CI 1.01, 1.75) became non-significant after adjustment for adiposity.

Conclusion

Physical HRQoL is a significant predictor of a range of adverse outcomes, even after adjustment for adiposity and other confounders. This study highlights the importance of perceived health in the general population.

Self-rated health and adverse events in CKD

BACKGROUND AND OBJECTIVES

Little is known about the utility of self-rated general health assessments in persons with moderate-to-severe CKD. This study examined the ability of a single self-rated health measure to predict all-cause mortality and kidney disease progression in a cohort of 443 patients with stages 3-4 CKD, recruited between 2005 and 2011, and followed until the end of 2012. The performance of models incorporating self-rated health measures was compared with previously published predictive models and more complex models comprising a multibiomarker panel.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

Participants were asked "In general, would you say your health is excellent, very good, good, fair, or poor?" Outcomes examined were time to all-cause mortality, kidney disease progression (initiation of RRT or 30% loss of eGFR), and a composite of these events. Model performances were compared using a nonparametric area under the curve (AUC) analysis.

RESULTS

Over a median follow-up of 3.3 years, 118 (27%) participants died and 138 (31%) had progression of kidney disease. Fair-to-poor self-rated health status was associated with significantly greater risks of mortality (fully adjusted hazard ratio [HR] for relative to good-to-excellent self-rated health, 2.76; 95% confidence interval [95% CI], 1.28 to 5.89), kidney disease progression (HR, 1.94; 95% CI, 1.49 to 2.56), and the combined end point (HR, 2.21; 95% CI, 1.66 to 2.96). For 3-year mortality prediction, the self-rated health model (AUC, 0.80; 95% CI, 0.76 to 0.85) had significantly higher AUCs than the base model (AUC, 0.71; 95% CI, 0.66 to 0.76) and the multibiomarker panel model (AUC, 0.74; 95% CI, 0.68 to 0.80) (P=0.03 and P=0.04, respectively).

CONCLUSIONS

A single, easily obtained measure of self-rated health helps identify patients with CKD at high risk of mortality and kidney disease progression. Routine evaluation of self-rated health may help target individuals who might benefit from more intensive monitoring strategies.

ARIZONA study: is the risk of post-herpetic neuralgia and its burden increased in the most elderly patients?

BACKGROUND

In a context of change in the demographic profile of the older population, to identify an age threshold for increased risk and burden of herpes zoster (HZ) in 70+ patients.

METHODS

Post hoc analysis of the 12-month French nationwide prospective observational ARIZONA cohort study. HZ was assessed by means of the following validated questionnaires: Neuropathic Pain Symptom Inventory (NPSI), Zoster Brief Pain Inventory (ZBPI), Short-Form health survey (SF-12), and Hospital Anxiety and Depression Scale (HADS).

RESULTS

644 general practitioners included 1,358 volunteer patients with acute HZ in the ARIZONA study; 609 patients (45%) were 70+. In 70+ patients, age did not increase rash severity or HZ-related pain intensity at diagnosis, but increased by 64% the frequency of ophthalmic zoster (from 5.5% in 70-74 years age-group to 9.0% in 85+ patients, p = NS). Age was significantly associated with low physical health as assessed by the SF-12 Physical Component Summary (SF-12 PCS) score and bad mood as assessed by the HADS depression score (p < 0.001). Within the year following HZ, post-herpetic neuralgia (PHN) was systematically but not significantly more frequent in 85+ patients than in the 70-74, 75-79, or 80-84 years age-groups (19.0% vs. 13.3%/15.3%/11.6% at month 3; 15.1% vs. 7.3%/11.0%/12.2% at month 6; 15.2% vs. 6.0%/8.0%/6.0% at month12, respectively). SF-12 PCS and HADS depression scores improved from day 0 to month 12 in all patients (p < 0.001). 85+ patients were more impaired than younger patients (p < 0.001), but without clear difference according to PHN.

CONCLUSIONS

This study did not show in 70+ patients a clear and significant age threshold at which disease burden increased, although for some domains the impact seemed higher among the oldest patients; the cut-off of 70 years remains thus relevant for clinical and epidemiological studies. However, at individual level, assessment of the burden of HZ and HZ-related pain appears necessary to improve management and prevent functional decline in the most vulnerable 70+ patients.

A Cross-Sectional Study of Physical Activity and Health-Related Quality of Life in an Elderly Indonesian Cohort

Introduction:

Improving health-related quality of life (QoL) may have far-reaching clinical implications, and previous studies have shown associations between participation in physical activity and higher QoL. However, it is unclear which types of physical activity are particularly beneficial and how much of this relationship is explained by instrumental activities of daily living (IADL) following physical activity.

Method:

This observational study measured frequency of participation in several different physical activities and IADL scores in a large elderly, community-dwelling sample. Hierarchical regression analyses were used to assess relationships between these variables and self-rated QoL using the Medical Outcome Survey SF-36 questionnaire.

Findings:

Participation in walking was found to be associated with higher QoL ratings in older men and women. IADL scores were correlated with QoL ratings but only partially mediated the association between walking and QoL. Participation in other types of physical activity was not significantly associated with QoL ratings.

Conclusion:

Walking may be recommended alongside treatment for illness or disability due to its potential benefits to QoL and treatment outcomes. Further research should investigate the role of physical fitness in this relationship, to determine whether these findings can be replicated in different populations.

Unplanned admissions and readmissions in older people: a review of recent evidence on identifying and managing high-risk individuals

Rising unplanned hospital admissions are a problem in ageing populations worldwide. These admissions are associated with poor outcomes for older people, contribute to rising health care costs and impede the provision of planned care. Policy and practice in recent years has focused on identification of those at risk of unplanned admission and early intervention via a range of admission avoidance services. Despite this, unplanned admissions in older people continue to rise, and managing demand for unplanned care remains a priority. Questions remain about the risk factors for unplanned admission and the best approaches to identifying and intervening with those at risk. This review explores recent evidence on admission rates, risk factors for unplanned admission in older people, identification of those at highest risk and interventions to avert unplanned admission.

Baseline health-related quality of life and 10-year all-cause mortality among 1739 Chinese adults

BACKGROUND AND PURPOSE

Health-related quality of life (HRQOL) may be associated with the longevity of patients; yet it is not clear whether this association holds in a general population, especially in low- and middle-income countries. The objective of this study was to determine whether baseline HRQOL was associated with 10-year all-cause mortality in a Chinese general population.

METHODS

A prospective cohort study was conducted from 2002 to 2012 on 1739 participants in 11 villages of Beijing. Baseline data on six domains of HRQOL, chronic diseases and cardiovascular risk factors were collected in either 2002 (n = 1290) or 2005 (n = 449). Subjects were followed through the end of the study period, or until they were censored due to death or loss to follow-up, whichever came first.

RESULTS

A multivariable Cox model estimated that Total HRQOL score (bottom 50% versus top 50%) was associated with a 44% increase in all-cause mortality (Hazard Ratio [HR] = 1.44; 95% confidence interval [CI]: 1.00-2.06), after adjusting for sex, age, education levels, occupation, marital status, smoking status, fruit intake, vegetable intake, physical exercise, hypertension, history of a stroke, myocardial infarction, chronic respiratory disease, and kidney disease. Among the six HRQOL domains, the Independence domain had the largest fully adjusted HR (HR = 1.66; 95% CI: 1.13-2.42), followed by Psychological (HR = 1.47; 95% CI: 1.03-2.09), Environmental (HR = 1.43, 95% CI: 1.003-2.03), Physical (HR = 1.38; 95% CI: 0.97-1.95), General (HR = 1.37; 95% CI: 0.97-1.94), and the Social domain (HR = 1.15; 95% CI: 0.81-1.65).

CONCLUSION

Lower HRQOL, especially the inability to live independently, was associated with a significantly increased risk of 10-year all-cause mortality. The inclusion of HRQOL measures in clinical assessment may improve diagnostic accuracy to improve clinical outcomes and better target public health promotions.

Health-related quality of life (HRQOL) decreases independently of chronic conditions and geriatric syndromes in older adults with diabetes: the Fujiwara-kyo Study

Background

Very few studies have investigated the association between diabetes and impaired health-related quality of life (HRQOL) in older adults, independent of chronic conditions and geriatric syndromes.

Methods

We conducted a self-administered questionnaire survey and structured interviews with 3946 people aged 65 years or older to obtain medical histories of diabetes, chronic conditions, and geriatric syndromes. Blood tests were performed to measure glycated hemoglobin (HbA1c) and plasma glucose levels. HRQOL was evaluated using the Medical Outcomes Study 36-Item Short-Form General Health Survey (SF-36), and multiple logistic regression analysis was used to calculate adjusted odds ratios and 95% CIs for low HRQOL.

Results

A total of 3521 participants had not received a physician diagnosis of diabetes. Of these, 2345 participants with an HbA1c less than 5.7% were defined as the referent group. As compared with the referent group, 1029 participants with an HbA1c of at least 5.7% but less than 6.5% showed no significant decrease in QOL on the SF-36 physical, mental, and role component summaries, after adjustment for chronic conditions, geriatric syndromes, and other potential confounders. However, 572 patients who had received a physician diagnosis of diabetes and/or had an HbA1c of 6.5% or higher had a significantly higher adjusted odds ratio (1.48; 95% CI, 1.18–1.84) for the low physical component summary. No significant differences in relation to glycemic control, treatment regimen, or diabetes duration were found in any of the 3 component summaries among the 425 participants who were undergoing diabetes treatment.

Conclusions

Older Japanese adults with diabetes had decreased physical QOL, independent of chronic conditions and geriatric syndromes.

Diabetes health information technology innovation to improve quality of life for health plan members in urban safety net

Safety net systems need innovative diabetes self-management programs for linguistically diverse patients. A low-income government-sponsored managed care plan implemented a 27-week automated telephone self-management support/health coaching intervention for English-, Spanish-, and Cantonese-speaking members from 4 publicly funded clinics in a practice-based research network. Compared to waitlist, immediate intervention participants had greater 6-month improvements in overall diabetes self-care behaviors (standardized effect size [ES] = 0.29, P < .01) and 12-Item Short Form Health Survey physical scores (ES = 0.25, P = .03); changes in patient-centered processes of care and cardiometabolic outcomes did not differ. Automated telephone self-management is a strategy for improving patient-reported self-management and may also improve some outcomes.

Geriatric conditions as predictors of increased number of hospital admissions and hospital bed days over one year: findings of a nationwide cohort of older adults from Taiwan

The main aim of the present study was to determine whether geriatric conditions independently predict hospital utilizations after controlling for chronic diseases and disability among community dwelling older adults. We analyzed data from a nationally representative sample of older adults aged 65 years and above by linkage of 2005 Taiwan National Health Interview Survey data (including demographic characteristics, chronic diseases, disability, and geriatric conditions such as depressive symptoms, cognitive impairment, falls, and urinary incontinence), and 2006 National Health Insurance (NHI) claims data (including hospital admissions and hospital bed days). A total of 1598 participants who consented to data linkage, were successfully linked to NHI data, and had complete data for geriatric conditions were eligible for analysis. The prevalence of depressive symptoms, cognitive impairment, falls, and urinary incontinence were 20.6%, 26.1%, 21.3% and 23.9%, respectively. Overall, 18.2% (291/1598) of participants had at least one hospital admission during 2006. After adjustment for demographics, prior hospitalization, chronic diseases and functional disability, participants with geriatric conditions had significantly more hospital admissions (incidence rate ratio=1.34; 95% confidence interval=[1.02-1.75]) and more hospital bed days (incidence rate ratio=1.72; 95% confidence interval=[1.11-2.66]) than participants without geriatric conditions. Our results highlight the high prevalence (56.3%) of one or more geriatric conditions and their independent association with excess hospital utilizations. Thus, it is of critical importance to develop programs aimed at preventing or improving these conditions to reduce hospital use in this population.

Quality of life in patients with knee osteoarthritis: a commentary on nonsurgical and surgical treatments

Knee osteoarthritis (OA) has a significant negative impact on health-related quality of life (HRQoL). Identification of therapies that improve HRQoL in patients with knee OA may mitigate the clinical, economic, and social burden of this disease. The purpose of this commentary is to report the impact of knee OA on HRQoL, describe the change in HRQoL attributable to common knee OA interventions, and summarize findings from clinical trials of a promising therapy. Nonsurgical therapies do not reliably modify HRQoL in knee OA patients given their general inability to alleviate physical manifestations of OA. Surgical knee OA interventions generally result in good to excellent patient outcomes. However, there are significant barriers to considering surgery, which limits clinical utility. Therapies that most effectively control OA-related pain with a low risk: benefit ratio will likely have the greatest benefit on HRQoL with greater rates of patient adoption. Initial clinical trial findings suggest that less invasive joint unloading implants hold promise in bridging the therapeutic gap between nonsurgical and surgical treatments for the knee OA patient.

Medical home interventions and quality outcomes for older adults: a systematic review

PURPOSE

Medical home care has been identified as a model for improving primary care delivery and population-specific quality and safety outcomes. Questions remain how this model affects older adult quality. This systematic review addresses 2 important questions: Are quality and safety outcomes associated with medical home and patient-centered interventions, and how is quality studied in older adult primary care research?

METHODS

The authors searched MEDLINE for articles that examined interventions that were associated with medical home principles. Each article was evaluated using a standardized data abstraction form. Studies were categorized according to how interventions influenced specific quality and safety outcomes-improved clinical and treatment measures and care delivery processes-for older adults.

RESULTS

Thirteen research studies were identified by the authors. A great deal of variety exists in both research design and how quality and safety outcomes for older adults are operationalized in primary care. In general, studies indicate potentially beneficial relationships between 3 types of medical home interventions targeting health care utilization, disease management, and patient-provider communication to improved quality outcomes.

CONCLUSION

It would be advantageous for practices looking to align with patient-centered medical home quality and safety goals to consider the needs of older adults when redesigning care delivery.

Health-related quality of life for infants in the neonatal intensive care unit

When discussing the benefits and burdens of medical interventions for critically ill infants, clinicians and families are challenged to weigh the uncertainties of treatment success with infant pain and suffering. Concrete measures of infant suffering or quality of life, which could inform infant care and decision-making are lacking. Although consistent and reliable health-related quality of life (HRQOL) definitions and measures have been extensively developed for adults and older children, they have not been relevant to neonates or infants. Advancing HRQOL research methodology is an objective of Healthy People 2020. This paper will review the evidence and practices relevant to HRQOL with a focus on intensive care and pediatric settings. We will highlight existing HRQOL measures, which could be adapted for neonates and existing neonatal intensive care unit measures and practices, which could inform new measures of HRQOL.

A prospective study of the impact of musculoskeletal pain and radiographic osteoarthritis on health related quality of life in community dwelling older people

BACKGROUND

Pain and radiographic changes are common in persons with osteoarthritis, but their relative contributions to quality of life are unknown.

METHODS

Prospective cohort study of 1098 men and women aged 50-80 years, randomly selected from the electoral roll. Participants were interviewed at baseline and approximately 2.6 and five years later. Participants self-reported prior diagnosis of arthritis and presence of joint pain. Joint space narrowing (JSN) and osteophytes at the hip and knee were assessed by X-ray. Quality of life (QoL) was assessed using the Assessment of QoL (AQoL) instrument. Data was analysed using linear regression and mixed modelling.

RESULTS

The median AQoL score at baseline was 7.0, indicating very good QoL. Prevalence of pain ranged from 38-62%. Over five years of observation, pain in the neck, shoulders, back, hips, hands, knees and feet were all independently and negatively associated with QoL, in a dose-response relationship. Diagnosed osteoarthritis at all sites was associated with poorer QoL but after adjustment for pain, this only remained significant at the back. Radiographic OA was not associated with QoL. While AQoL scores declined over five years, there was no evidence of an interaction between pain and time.

CONCLUSIONS

Pain is common in older adults, is stable over time, and the strongest musculoskeletal correlate of QoL. It also mediates the association between diagnosed OA and QoL. Since the same factors were associated with quality of life over time as at baseline, this suggests that quality of life tracks over a five year period.

Gender differences in health-related quality of life among cannabis users: results from the National Epidemiologic Survey on Alcohol and Related Conditions

BACKGROUND

Cannabis is the most widely used illicit substance worldwide. The aim of the present study was to assess self-reported Quality of Life (QoL) among cannabis users in a large representative sample.

METHODS

We analyzed data from the National Epidemiological Survey of Alcohol and Related Conditions (NESARC, n=43,093). Health-related QoL was assessed using the Short-form 12-item Health Survey (SF-12). The contribution of cannabis use and cannabis use disorders (CUD) to SF-12 scores was assessed using multiple linear regressions models.

RESULTS

The prevalence of cannabis use and CUD in the last 12 months was 4.1% and 1.5%, respectively. Mean SF-12 mental summary scores were significantly lower (indicating a lower QoL) among female and male cannabis users compared to non-users (by 0.6 standard deviations (SD) and 0.3 SD, respectively), and among females and males with CUD compared to those without CUD (by 0.9 SD and 0.4 SD, respectively). Controlling for sociodemographic variables and mental illness, each joint smoked daily was associated with a greater decrease in mental QoL summary scores in females (0.1 SD) compared to males (0.03 SD).

CONCLUSIONS

Cannabis use and CUD were associated with lower self-reported mental QoL. Specifically, our findings showed that cannabis use and CUD have a more significant effect on self-reported mental health QoL among female users. Assessing severity of cannabis use and impact of CUD should take into account functional and emotional outcomes. This may particularly aid in detecting the impact of cannabis use and CUD on mental health-related QoL among females.

Quality of life in the care home: a qualitative study of the perspectives of residents with multiple sclerosis

PURPOSE

Care home residents with multiple sclerosis (MS) are more physically dependent than the average residents. However, little is known about their quality of life (QoL). We investigated the experiences of residents with MS using qualitative research methods and developed a conceptual model of QoL.

METHODS

Twenty-one people with MS (age range 43-80 years) residing in a range of care homes were interviewed. The interviews were transcribed verbatim and analyzed using the constant comparative method.

RESULTS

Four core model domains identified were as follows: (i) What the care home means to the residents, (ii) Self, (iii) Environment and (iv) Relationships. Some residents reported that care homes can relieve the burden on family, address specific environmental issues regarding safety and act as a form of social support. However, some reported isolation and difficulties adjusting to life in the care home. Having access to rehabilitation strengthened the feelings of independence within the care home.

CONCLUSIONS

QoL is a broad, multidimensional construct for residents with MS. QoL measures for residents with MS should incorporate broad domains, including environmental factors. The conceptual model highlighted several areas for improving QoL of residents with MS, including more involvement of family members, encouraging independence by providing access to rehabilitation and providing support in the transition process.

Development of a prognostic model for six-month mortality in older adults with declining health

CONTEXT

Estimation of six-month prognosis is essential in hospice referral decisions, but accurate, evidence-based tools to assist in this task are lacking.

OBJECTIVES

To develop a new prognostic model, the Patient-Reported Outcome Mortality Prediction Tool (PROMPT), for six-month mortality in community-dwelling elderly patients.

METHODS

We used data from the Medicare Health Outcomes Survey linked to vital status information. Respondents were 65 years old or older, with self-reported declining health over the past year (n=21,870), identified from four Medicare Health Outcomes Survey cohorts (1998-2000, 1999-2001, 2000-2002, and 2001-2003). A logistic regression model was derived to predict six-month mortality, using sociodemographic characteristics, comorbidities, and health-related quality of life (HRQOL), ascertained by measures of activities of daily living and the Medical Outcomes Study Short Form-36 Health Survey; k-fold cross-validation was used to evaluate model performance, which was compared with existing prognostic tools.

RESULTS

The PROMPT incorporated 11 variables, including four HRQOL domains: general health perceptions, activities of daily living, social functioning, and energy/fatigue. The model demonstrated good discrimination (c-statistic=0.75) and calibration. Overall diagnostic accuracy was superior to existing tools. At cut points of 10%-70%, estimated six-month mortality risk sensitivity and specificity ranged from 0.8% to 83.4% and 51.1% to 99.9%, respectively, and positive likelihood ratios at all mortality risk cut points ≥40% exceeded 5.0. Corresponding positive and negative predictive values were 23.1%-64.1% and 85.3%-94.5%. Over 50% of patients with estimated six-month mortality risk ≥30% died within 12 months.

CONCLUSION

The PROMPT, a new prognostic model incorporating HRQOL, demonstrates promising performance and potential value for hospice referral decisions. More work is needed to evaluate the model.

Measures of multimorbidity and morbidity burden for use in primary care and community settings: a systematic review and guide

PURPOSE

Many patients consulting in primary care have multiple conditions (multimorbidity). Aims of this review were to identify measures of multimorbidity and morbidity burden suitable for use in research in primary care and community populations, and to investigate their validity in relation to anticipated associations with patient characteristics, process measures, and health outcomes.

METHODS

Studies were identified using searches in MEDLINE and EMBASE from inception to December 2009 and bibliographies.

RESULTS

Included were 194 articles describing 17 different measures. Commonly used measures included disease counts (n = 98), Chronic Disease Score (CDS)/RxRisk (n = 17), Adjusted Clinical Groups (ACG) System (n = 25), the Charlson index (n = 38), the Cumulative Index Illness Rating Scale (CIRS; n = 10) and the Duke Severity of Illness Checklist (DUSOI; n = 6). Studies that compared measures suggest their predictive validity for the same outcome differs only slightly. Evidence is strongest for the ACG System, Charlson index, or disease counts in relation to care utilization; for the ACG System in relation to costs; for Charlson index in relation to mortality; and for disease counts or Charlson index in relation to quality of life. Simple counts of diseases or medications perform almost as well as complex measures in predicting most outcomes. Combining measures can improve validity.

CONCLUSIONS

The measures most commonly used in primary care and community settings are disease counts, Charlson index, ACG System, CIRS, CDS, and DUSOI. Different measures are most appropriate according to the outcome of interest. Choice of measure will also depend on the type of data available. More research is needed to directly compare performance of different measures.

Mortality risk by functional status and health-related quality of life in patients with rheumatoid arthritis

OBJECTIVE

Patients with rheumatoid arthritis (RA) are at increased risk of death. Modern RA therapy has been shown to improve health status, but the relationship of such improvements to mortality risk is unknown. We assessed the relationship between health status and all-cause mortality in patients with RA, using the Health Assessment Questionnaire (HAQ) and the Medical Outcomes Study Short Form-36 questionnaire (SF-36) physical and mental component summary scores (PCS, MCS).

METHODS

Subjects (n = 10,319) were selected from the National Data Bank for Rheumatic Diseases, a prospective longitudinal observational US study with semiannual assessments of HAQ, PCS, and MCS. Risk of death up to 7 years through 2006 was obtained from the US National Death Index. Relationship of HAQ, PCS, and MCS to mortality was assessed using Cox regression models; prediction accuracy was compared using Harrell's concordance coefficient (C).

RESULTS

Over 64,888 patient-years of followup, there were 1317 deaths. Poorer baseline health status was associated with greater mortality risk. Adjusting for age, sex, and baseline PCS and MCS, declines in PCS and HAQ were associated with higher risk of death. HAQ improvement was associated with reduced mortality risk from 6 months through 3 years; a similar relationship was not observed for PCS or MCS improvement. Controlling for baseline values, change in PCS or HAQ did not improve prediction accuracy.

CONCLUSION

The HAQ and the SF-36 PCS are similarly and strongly associated with mortality risk in patients with RA. Change in these measures over time does not appear to add to predictive accuracy over baseline levels.

Cognitive impairment and outcomes in older adult survivors of acute myocardial infarction: findings from the translational research investigating underlying disparities in acute myocardial infarction patients' health status registry

BACKGROUND

Cognitive impairment without dementia (CIND) and acute myocardial infarction (AMI) are prevalent in older adults; however, the association of CIND with outcomes after AMI is unknown.

METHODS

We used a multicenter registry to study 772 patients ≥65 years with AMI, enrolled between April 2005 and December 2008, who underwent cognitive function assessment with the Telephone Interview for Cognitive Status-modified (TICS-m) 1 month after AMI. Patients were categorized by cognitive status to describe characteristics and in-hospital treatment, including quality of life and survival 1 year after AMI.

RESULTS

Mean age was 73.2 ± 6.3 years; 58.5% were men, and 78.2% were white. Normal cognitive function (TICS-m >22) was present in 44.4%; mild CIND (TICS-m 19-22) in 29.8%; and moderate/severe CIND (TICS-m <19) in 25.8% of patients. Rates of hypertension (72.6%, 77.4%, and 81.9%), cerebrovascular accidents (3.5%, 7.0%, and 9.0%), and myocardial infarction (20.1%, 22.2%, and 29.6%) were higher in those with lower TICS-m scores (P < .05 for comparisons). AMI medications were similar by cognitive status; however, CIND was associated with lower cardiac catheterization rates (P = .002) and cardiac rehabilitation referrals (P < .001). Patients with moderate/severe CIND had higher risk-adjusted 1-year mortality that was nonstatistically significant (adjusted hazard ratio 1.97, 95% CI 0.99-3.94, P = .054; referent normal, TICS-m >22). Quality of life across cognitive status was similar at 1 year.

CONCLUSIONS

Most older patients surviving AMI have measurable CIND. Cognitive impairment without dementia was associated with less invasive care, less referral and participation in cardiac rehabilitation, and worse risk-adjusted 1-year survival in those with moderate/severe CIND, making it an important condition to consider in optimizing AMI care.

Self-perceived quality of life predicts mortality risk better than a multi-biomarker panel, but the combination of both does best

Background

Associations between measures of subjective health and mortality risk have previously been shown. We assessed the impact and comparative predictive performance of a multi-biomarker panel on this association.

Methods

Data from 4,261 individuals aged 20-79 years recruited for the population-based Study of Health in Pomerania was used. During an average 9.7 year follow-up, 456 deaths (10.7%) occurred. Subjective health was assessed by SF-12 derived physical (PCS-12) and mental component summaries (MCS-12), and a single-item self-rated health (SRH) question. We implemented Cox proportional-hazards regression models to investigate the association of subjective health with mortality and to assess the impact of a combination of 10 biomarkers on this association. Variable selection procedures were used to identify a parsimonious set of subjective health measures and biomarkers, whose predictive ability was compared using receiver operating characteristic (ROC) curves, C-statistics, and reclassification methods.

Results

In age- and gender-adjusted Cox models, poor SRH (hazard ratio (HR), 2.07; 95% CI, 1.34-3.20) and low PCS-12 scores (lowest vs. highest quartile: HR, 1.75; 95% CI, 1.31-2.33) were significantly associated with increased risk of all-cause mortality; an association independent of various covariates and biomarkers. Furthermore, selected subjective health measures yielded a significantly higher C-statistic (0.883) compared to the selected biomarker panel (0.872), whereas a combined assessment showed the highest C-statistic (0.887) with a highly significant integrated discrimination improvement of 1.5% (p < 0.01).

Conclusion

Adding biomarker information did not affect the association of subjective health measures with mortality, but significantly improved risk stratification. Thus, a combined assessment of self-reported subjective health and measured biomarkers may be useful to identify high-risk individuals for intensified monitoring.

Health-related quality of life across the anxiety disorders: results from the national epidemiologic survey on alcohol and related conditions (NESARC)

OBJECTIVE

Although clinical studies have documented that specific anxiety disorders are associated with impaired psychosocial functioning, little is known regarding their comparative effects on health-related quality of life within a general population. The current analysis compares health-related quality of life in a US community-dwelling sample of adults with DSM-IV social anxiety disorder, generalized anxiety disorders (GAD), panic disorder, and specific phobia.

METHOD

A face-to-face survey of a US nationally representative sample of over 43,000 adults aged 18 years and older residing in households and group quarters was conducted. Prevalence of DSM-IV anxiety disorders and relative associations with health-related quality of life indicators were examined. The survey was conducted from 2001 to 2002.

RESULTS

Roughly 9.8% of respondents met diagnostic criteria for at least 1 of 4 twelve-month DSM-IV anxiety disorders which, relative to the non-anxiety-disordered general population, were each associated with lower personal income, increased rates of 12-month physical conditions, and greater numbers of Axis I and Axis II DSM-IV psychiatric conditions. After adjusting for sociodemographic and clinical correlates, including other anxiety disorders, GAD was associated with significant decrements in the SF-12 mental component summary score. In similar models, GAD and, to a lesser extent, panic disorder were significantly associated with impairment in social functioning, role emotional, and mental health SF subscales.

CONCLUSIONS

GAD, followed by panic disorder, appears to exact significant and independent tolls on health-related quality of life. Results underscore the importance of prompt and accurate clinical identification and improving access to effective interventions for these disorders.

Health-related quality of life in Hispanics with chronic kidney disease

Health-related quality of life (HRQOL) is an important patient-reported outcome that has gained attention in research and clinical practice. In recent years, reports of chronic kidney disease (CKD) have increased. However, not much information is available for Hispanics with CKD, a group whose rates of incidents are on the rise. This review discusses the measurement of HRQOL in CKD, with a particular focus on issues pertaining to Hispanics. Future research directions also are discussed.

Implications of excess weight on mental wellbeing

Objective.To assess differences in perceived health-related quality of life among individuals who are normal weight, overweight and obese in the general population, with particular emphasis on mental health. Method.A cross-sectional study was conducted among the general adult population in Queensland, Australia. Participants (n = 1212) were selected randomly for computer-assisted telephone interview in July 2007. The sample ranged between 18 and 93 years, with a mean age of 51.10 years (s.d. = 15.92). Demographic and physical and mental health (SF-12) data were collected. Self-reported height and weight were used to classify participants into three groups based on their body mass index: normal weight; overweight; obese. The associations between body mass index categories and SF-12 scores were investigated. Results.In this population sample, excess weight was associated with poorer physical health. In addition, significant associations were observed between excess weight and poor mental health for particular age groups. Obesity had a significant association with poor mental wellbeing for individuals who are aged 45 to 54 years. No sex differences were observed. Conclusion.The results provide additional evidence of the relationship between excess weight and mental wellbeing and highlight the need for health professionals to be cognisant of the potential for individuals who are obese to have a higher risk of experiencing mental health problems. What is known about the topic?The body mass index of the general population is rising steadily. Being overweight or obese has a detrimental effect on physical health and is a major cause of preventable death. However, there are conflicting findings regarding the implications of excess weight on an individuals’ mental health. What does this paper add?This paper substantiates the relationship between body mass index and health-related quality of life in the general adult population. Obesity was associated with poor mental wellbeing for individuals between the ages of 45 and 54. What are the implications for practice?This study underscores the need for mental health and wellbeing to become part of standard assessment practice for individuals who are overweight or obese, particularly those aged between 45 and 54 years.

Comparison of health outcomes for male seniors in the Veterans Health Administration and Medicare Advantage plans

OBJECTIVES

To compare the Veterans Health Administration (VHA) with the Medicare Advantage (MA) plans with regard to health outcomes.

DATA SOURCES

The Medicare Health Outcome Survey, the 1999 Large Health Survey of Veteran Enrollees, and the Ambulatory Care Survey of Healthcare Experiences of Patients (Fiscal Years 2002 and 2003).

STUDY DESIGN

A retrospective study.

EXTRACTION METHODS

Men 65+ receiving care in MA (N=198,421) or in VHA (N=360,316). We compared the risk-adjusted probability of being alive with the same or better physical (PCS) and mental (MCS) health at 2-years follow-up. We computed hazard ratio (HR) for 2-year mortality.

PRINCIPAL FINDINGS

Veterans had a higher adjusted probability of being alive with the same or better PCS compared with MA participants (VHA 69.2 versus MA 63.6 percent, p<.001). VHA patients had a higher adjusted probability than MA patients of being alive with the same or better MCS (76.1 versus 69.6 percent, p<.001). The HRs for mortality in the MA were higher than in the VHA (HR, 1.26 [95 percent CI 1.23-1.29]).

CONCLUSIONS

Our findings indicate that the VHA has better patient outcomes than the private managed care plans in Medicare. The VHA's performance offers encouragement that the public sector can both finance and provide exemplary health care.

Quality of life and mortality from a nephrologist's view: a prospective observational study

BACKGROUND

Although health-related quality of life (HRQOL) is a potential independent predictor of mortality, nephrologists have shown little interest in HRQOL with respect to mortality in chronic kidney disease (CKD). The aim of this article is to evaluate the impact of HRQOL on mortality in the elderly, who are likely to develop or already have CKD.

METHODS

Among 1,000 randomly sampled participants aged more than 65 years (sourced from the Korean Longitudinal Study on Health and Ageing), 944 subjects were evaluated for HRQOL. HRQOL was assessed using a 36-item Short-Form health survey (SF36). A cumulative survival rate was calculated according to tertiles of SF36 scores and classified by the presence of CKD (estimated GFR <60 ml/min/1.73 m2).

RESULTS

Among 944 subjects, 46.6% had CKD. CKD patients had lower total and physical component scores compared with subjects without CKD. The 3-year cumulative survival rate was 90.0% (non-CKD vs. CKD: 92.6% vs. 87.4%, P = 0.005 by log rank test). After adjusting for multiple variables, a reduced SF36 score (physical and mental components) was a strong predictor of all-cause mortality. Physical components were consistently able to predict mortality after CKD classification, but mental components were statistically significant only in the CKD group.

CONCLUSION

In addition to traditional risk factors of mortality, nephrologists should be aware of HRQOL as a predictor of mortality and should make efforts to improve HRQOL in CKD patients.

Successful aging in health adversity: results from the National Psychiatric Morbidity Survey

BACKGROUND

We aimed to investigate factors enabling older people with cognitive impairment to age successfully.

METHODS

We used the 12-item Short Form Health Survey to measure health-related quality of life (HR-QoL) in 2,007 people aged > or =60 in the 2000 British National Psychiatric Morbidity Survey. We tested the hypothesis that affective symptoms and social support mediated the relationship between cognitive functioning and poorer HR-QoL.

RESULTS

The mean age of the participants was 66.2 (66.0-66.4). The majority of people with suspected dementia reported high mental health-related quality of life, suggesting they may not be distressed by, or aware of, cognitive and mental impairment, and the majority are aging "successfully." The relationship between cognitive impairment and mental HR-QoL was mediated by affective symptoms, but not by social support. After considering mediators and confounders, HR-QoL was no longer associated with cognitive impairment.

CONCLUSIONS

The lower quality of life previously reported by people with cognitive impairment is due to the greater physical and mental health problems in this population, rather than to cognitive impairment per se. Active management of mental and physical health may improve the HR-QoL of those with cognitive impairment who are not ageing successfully.

Differences in risk-adjusted mortality between medicaid-eligible patients enrolled in medicare advantage plans and those enrolled in the veterans health administration

BACKGROUND

We compared risk-adjusted mortality rates between Medicaid-eligible patients in the Medicare Advantage plans ("MA dual enrollees") and Medicaid-eligible patients in the Veterans Health Administration ("VHA dual enrollees").

METHODS

We used the Death Master File to ascertain the vital status of 1912 MA and 2361 VHA dual enrollees. We used Cox regression models to estimate hazard ratios (HRs) with 95% confidence intervals (CIs).

RESULTS

The 3-year mortality rates of VHA and MA dual enrollees were 15.8% and 19.0%, respectively. The adjusted HR of mortality in the MA dual enrollees was significantly higher than in the VHA dual enrollees (HR, 1.260 [95% CI, 1.044-1.520]). This was also the case for elderly patients and those from racial/ethnic minority groups.

CONCLUSIONS

The VHA had better health outcomes than did MA plans. The VHA's performance is reassuring, given its emphasis on equal access to healthcare in an environment that is less dependent on patient financial considerations.

Survival analysis in amputees based on physical independence grade achievement

BACKGROUND

Survival implications of achieving different grades of physical independence after lower extremity amputation are unknown.

OBJECTIVES

To identify thresholds of physical independence achievement associated with improved 6-month survival and to identify and compare other risk factors after removing the influence of the grade achieved.

DESIGN

Data were combined from 8 administrative databases. Grade was measured on the basis of 13 individual self-care and mobility activities measured at inpatient rehabilitation discharge.

SETTING

Ninety-nine US Department of Veterans Affairs Medical Centers.

PATIENTS

Retrospective longitudinal cohort study of 2616 veterans who underwent lower extremity amputation and subsequent inpatient rehabilitation between October 1, 2002, and September 30, 2004.

MAIN OUTCOME MEASURE

Cumulative 6-month survival after rehabilitation discharge.

RESULTS

The 6-month survival rate (95% confidence interval [CI]) for those at grade 1 (total assistance) was 73.5% (70.5%-76.2%). The achievement of grade 2 (maximal assistance) led to the largest incremental improvement in prognosis with survival increasing to 91.1% (95% CI, 85.6%-94.5%). In amputees who remained at grade 1, the 30-day hazards ratio for survival compared with grade 6 (independent) was 43.9 (95% CI, 10.8-278.2), sharply decreasing with time. Whereas metastatic cancer and hemodialysis remained significantly associated with reduced survival (both P < or = .001), anatomical amputation level was not significant when rehabilitation discharge grade and other diagnostic conditions were considered.

CONCLUSIONS

Even a small improvement to grade 2 in the most severely impaired amputees resulted in better 6-month survival. Health care systems must plan appropriate interdisciplinary treatment strategies for both medical and functional issues after amputation.

The direct and indirect cost burden of Crohn's disease and ulcerative colitis

OBJECTIVE

To estimate the direct medical and indirect (absenteeism and short-term disability) cost burden of Crohn's Disease (CD) and Ulcerative Colitis (UC).

METHODS

Data were obtained from 1999 to 2005 MarketScan databases. Twelve-month expenditures for patients with CD and UC were compared to expenditures among an equal number of propensity score matched comparison group patients. Regression analysis controlled for demographics and case-mix.

RESULTS

Annual medical expenditures were significantly higher for commercially insured CD and UC patients compared to matched comparison group patients ($18,963 vs $5300 for CD patients, $15,020 vs $4982 for UC patients, respectively, all P < 0.001). Indirect costs were also high for employed patients with these conditions.

CONCLUSIONS

CD and UC are costly diseases with a significant cost burden related to health care utilization and productivity loss.

The effect of technology-supported, multidisease care management on the mortality and hospitalization of seniors

OBJECTIVES

To explore changes in mortality and hospital usage for chronically ill seniors enrolled in a multidisease care management program, Care Management Plus (CMP).

DESIGN

Controlled clinical trial with seven intervention and six control clinics with additional patient-level matching.

SETTING

Intermountain Health Care, a large health system in Utah; seven intervention and six control clinics.

PARTICIPANTS

Three thousand four hundred thirty-two senior patients (>or=65) enrolled in Medicare.

INTERVENTION

The intervention employed nurse care managers supported by specialized information technology in primary care to manage chronically ill patients (2002-2005).

MEASUREMENTS

Mortality and hospitalization data were collected from clinical records and Medicare billing.

RESULTS

One thousand one hundred forty-four intervention patients were matched to 2,288 controls. Average age was 76.2; average comorbidity score was 2.3+/-1.1; 75% of patients had two or more chronic diseases. Survival analyses showed lower mortality and slightly more emergency department visits for care managed patients than for controls. In patients with diabetes mellitus, the intervention resulted in significantly lower mortality at 1 year (6.2%, vs 10.6% for controls) and at 2 years (12.9% vs 18.2%). Hospitalization rate was lower (21.0%, vs. 24.2% for controls) at 1 year and substantially more so at the 2-year follow-up.

CONCLUSION

CMP was successful in reducing death for all patients. For complex patients with diabetes mellitus in the intervention group, death and hospital usage were lower. Per clinic, hypothesized savings from decreased hospitalizations was $17,384 to $70,349.

The effect of age on functional and mortality outcomes after acute myocardial infarction

OBJECTIVES

To determine the prevalence of post-myocardial infarction (MI) functional decline and to describe its association with chronological age in survivors of MI.

DESIGN

Prospective observational registry.

SETTING

Nineteen U.S. hospitals.

PARTICIPANTS

Two thousand four hundred eighty-one patients with acute MI.

MEASUREMENTS

Baseline and 1-year interviews identified subjects with functional decline, defined as a more than 5-point decline in Medical Outcomes Study 12-item Short Form Questionnaire (SF-12) Physical Component score or being "too ill" to provide a follow-up interview at 1 year. The relationship between age and functional decline was evaluated using logistic regression models adjusted for baseline SF-12 score, comorbidities, sociodemographics, and treatment characteristics. One-year mortality and a combined endpoint of death or decline were also compared across age.

RESULTS

Of 2,009 patients who survived to 1 year, 582 (29%) experienced a functional decline. In survivors, age was not associated with functional decline in unadjusted (odds ratio (OR)=0.95/decade, 95% confidence interval (CI)=0.88-1.03) or multivariable (OR=0.94, 95% CI=0.85-1.05) models. Although age was strongly associated with 1-year mortality (adjusted hazard ratio=1.42, 95% CI=1.21-1.66), there was no association between age and the combined endpoint of death or functional decline (adjusted OR=1.02, 95% CI=0.92-1.12).

CONCLUSION

More than one in four survivors of MI experiences a significant decline in physical function by 1 year. Although age is strongly associated with mortality, it had no association with functional decline. Because older patients have the same potential for favorable functional outcomes after an MI, age alone should not preclude aggressive treatment after an MI.

Prospective change in health-related quality of life and subsequent mortality among middle-aged and older women

OBJECTIVES

We sought to determine prospective changes in health-related quality of life (HRQoL) measures and subsequent mortality in middle-aged and older women.

METHODS

We obtained data from 40 337 healthy women from the Nurses' Health Study aged 46 to 71 years in 1992. We used Cox proportional hazards regression to evaluate associations of changes in self-assessed physical and mental component summary (PCS and MCS) scores from the Short Form 36 Health Survey between 1992 and 1996 and between 1996 and 2000, with all-cause mortality through 2004.

RESULTS

Women with low HRQoL (PCS and MCS scores) and the greatest HRQoL declines had higher mortality than did women with stable scores. Change in PCS score predicted mortality across the range of 4-year change: severe decline (relative risk [RR] = 3.32; 95% confidence interval [CI] = 2.45, 4.50), moderate decline (RR = 1.44; 95% CI = 1.16, 1.79), slight decline (RR = 1.35; 95% CI = 1.12, 1.63), no change (reference category), improvement (RR = 0.72; 95% CI = 0.56, 0.91; continuous P < .001). MCS score results were similar. Score increases were associated with lifestyle improvements, especially increased physical activity.

CONCLUSIONS

Observed associations demonstrate the predictive validity of changes in self-assessed HRQoL for subsequent mortality in healthy populations. Future research should examine determinants of patterns of change.

Risk factors for hospitalization among community-dwelling primary care older patients: development and validation of a predictive model

BACKGROUND

Unplanned hospitalization often represents a costly and hazardous event for the older population.

OBJECTIVES

To develop and validate a predictive model for unplanned medical hospitalization from administrative data.

RESEARCH DESIGN

Model development and validation.

SUBJECTS

A total of 3919 patients aged > or =70 years who were followed for at least 1 year in primary care clinics of an academic medical center.

MEASURES

Risk factor data and the primary outcome of unplanned medical hospitalization were obtained from administrative data.

RESULTS

Of 1932 patients in the development cohort, 299 (15%) were hospitalized during 1 year follow up. Five independent risk factors were identified in the preceding year: Deyo-Charlson comorbidity score > or =2 [adjusted relative risk (RR) = 1.8; 95% confidence interval (CI): 1.4-2.2], any prior hospitalization (RR = 1.8; 95% CI: 1.5-2.3), 6 or more primary care visits (RR = 1.6; 95% CI: 1.3-2.0), age > or =85 years (RR = 1.4; 95% CI: 1.1-1.7), and unmarried status (RR = 1.4; 95% CI: 1.1-1.7). A risk stratification system was created by adding 1 point for each factor present. Rates of hospitalization for the low- (0 factor), intermediate- (1-2 factors), and high-risk (> or =3 factors) groups were 5%, 15%, and 34% (P < 0.0001). The corresponding rates in the validation cohort, where 328/1987 (17%) were hospitalized, were 6%, 16%, and 36% (P < 0.0001).

CONCLUSIONS

A predictive model based on administrative data has been successfully validated for prediction of unplanned hospitalization. This model will identify patients at high risk for hospitalization who may be candidates for preventive interventions.

Challenges of Noncancer Patients Transitioning to Hospice

The traditional model of hospice care based on the course of incurable cancer with rapid decline and death does not apply to chronic diseases. Cancer also may take a chronic course and no longer accounts for the majority of admissions to hospice. Hospice admissions now include a majority of noncancer diagnoses. The second challenge is the wide disparity between chronic disease courses. Case examples of people with different diagnoses demonstrate a variety of contrasting trajectories of illness. With ever-increasing advances in medical care, the indications for intensive treatments have never overlapped so much with the indications for hospice referral. This represents the third challenge. In addition, some treatments and medications that improve symptoms and quality of life may significantly prolong life, thus contradicting the traditional expectation of “foregoing life-sustaining treatment” in favor of enrolling in hospice. Finally, a description of various assessment tools helps in identifying the indications for hospice.

Potential economic impact of hospital-acquired infections in uninsured patients: a preliminary investigation

We studied uninsured patients admitted to Rhode Island Hospital from January 1 through June 30, 2005, and from January 1 through June 30, 2006. The mean total hospital charge for an uninsured patient with a hospital-acquired infection was $18,487; for those without such an infection, it was $4,951 (P < .001). Multivariable linear regression revealed that a hospital-acquired infection accounted for 11.8 excess hospital days (P = .001). Length of stay was the only independent variable associated with total excess hospital charges.

Self-reported health status of vietnamese and non-Hispanic white older adults in california

Vietnamese Americans are a rapidly growing minority group in the United States, yet little is known about their health status. Chronic medical conditions and self-rated health of older Vietnamese Americans were compared with those of non-Hispanic white adults living in California using the 2001 and 2003 California Health Interview Surveys (CHISs). The CHIS employed a random-digit-dial telephone survey, and its sample is representative of California's noninstitutionalized population. The sample included 359 Vietnamese and 25,177 non-Hispanic white adults aged 55 and older. Vietnamese and non-Hispanic white adults were compared in terms of limitations in activities of daily living, chronic medical conditions (diabetes mellitus, hypertension, heart disease, asthma), mental health care, and self-reported health, adjusting for age, sex, and education. Vietnamese were more likely than white participants to report needing help for mental health problems (adjusted odds ratio (aOR)=2.1, 95% confidence interval (CI)=1.4-3.1) but less likely to have had their medical providers discuss their mental health problems with them (aOR=0.3, 95% CI=0.1-0.5). In addition, Vietnamese participants reported significantly worse health than white adults on five of eight domains of the Medical Outcomes Survery 12-item Short Form survey (P<.006). Clinicians caring for older Vietnamese individuals should be aware of the high risk for mental health needs in this population and should initiate discussions about mental health with their patients. Further research is needed to better understand why older Vietnamese Americans are at higher risk for worse self-reported health than older white adults.

Continuity of health insurance coverage and perceived health at age 40

While a lack of health insurance or interrupted coverage has been shown to lead to poorer health status among preretirement populations, this phenomenon has not been examined among a large population of younger, working-age adults. We analyzed a nationally representative data set of persons born between 1957 and 1961, the National Longitudinal Survey of Youth-1979, to examine the links between insurance continuity and self-assessed physical and mental health at age 40. Among respondents turning 40 in 1998 or 2000, 59.8% had been continuously insured during the decade before they reached age 40. In unadjusted analysis, persons who were continuously covered had the highest scores for both physical and mental health. After controlling for respondent characteristics, insurance coverage was not significantly associated with perceived physical or mental health.

The prognostic significance of patient-reported outcomes in cancer clinical trials

PURPOSE

Patient-reported outcomes (PROs), routinely collected as a part of cancer clinical trials, have been linked with survival in numerous clinical studies, but a comprehensive critical review has not been reported. This study systematically assessed the impact of PROs on patient survival after a cancer diagnosis within the context of clinical trials.

DESIGN

Cancer clinical trials that assessed baseline PROs and mortality were identified through MEDLINE (through December 2006) supplemented by the Cochrane database, American Society of Clinical Oncology/European Society for Medical Oncology abstracts and hand searches. Inclusion criteria were publication in English language and use of multivariate analyses of PROs that controlled for one or more clinical factors. Two raters reviewed each study, abstracted data, and assessed study quality; two additional raters verified abstractions.

RESULTS

In 36 of 39 studies (N = 13,874), at least one PRO was significantly associated with survival (P < .05) in multivariate analysis, with varying effect sizes. Studies of lung (n = 12) and breast cancer (n = 8) were most prevalent. The most commonly assessed PRO was quality of life, measured by the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 in 56% of studies. Clinical variables adjusted for included performance status (PS), treatment arm, stage, weight loss, and serum markers. Results indicated that PROs provide distinct prognostic information beyond standard clinical measures in cancer clinical trials.

CONCLUSION

PROs might be considered for stratification purposes in future trials, as they were often better predictors of survival than PS. Studies are needed to determine whether interventions that improve PROs also increase survival and to identify explanatory mechanisms through which PROs relate to survival.

Health related quality of life in older Mexican Americans with diabetes: a cross-sectional study

BACKGROUND

The older Hispanic population of the U.S. is growing at a tremendous rate. While ethnic-related risk and complications of diabetes are widely-acknowledged for older Hispanics, less is known about how health related quality of life is affected in this population.

METHODS

Cross-sectional study assessing differences in health related quality of life between older Mexican Americans with and without diabetes. Participants (n = 619) from the Hispanic Established Population for the Epidemiological Study of the Elderly were interviewed in their homes. The primary measure was the Medical Outcomes Study Short Form (SF-36).

RESULTS

The sample was 59.6% female with a mean age of 78.3 (SD = 5.2) years. 31.2% (n = 193) of the participants were identified with diabetes. Individuals with diabetes had significantly (F = 19.35, p < .001) lower scores on the Physical Composite scale (mean = 37.50, SD = 12.69) of the SF-36 compared to persons without diabetes (mean = 43.04, SD = 12.22). There was no significant difference between persons with and without diabetes on the Mental Composite scale of the SF-36.

CONCLUSION

Diabetes was associated with lower health related quality of life in older Mexican Americans. The physical components of health related quality of life uniformly differentiated those with diabetes from those without, whereas mental component scores were equivocal.

Care management dosage

BACKGROUND

The care of patients with complex illnesses requires careful management, but systems of care management (CM) vary in their structure and effectiveness.

OBJECTIVE

To create a framework identifying components of broad-based CM interventions and validate the framework, including using this framework to evaluate the contribution of varying components on outcomes of patients with chronic illness.

DESIGN

We create the framework using retrospective information about CM activities and services over 12 months and categorize it using cluster and factor analysis. We then validate this framework through content and criterion techniques. Content validity is assessed through a Delphi study and criterion validity through relationship of the dosage measures and patterns of care to process and outcomes measures.

PARTICIPANTS

Patients with diabetes and/or cardiovascular disease receiving CM services in a model known as Care Management Plus implemented in primary care.

RESULTS

Six factors of CM activity were identified, including a single dosage summary measure and 5 separate patterns of care. Of these, the overall dosage summary measure, face-to-face time, duration of follow-up, and breadth of services were all related to improved processes for hemoglobin A1c and LDL testing and control. Brief intense patterns of care and high face-to-face care manager time were also related to improved outcomes.

CONCLUSIONS

Using this framework, we isolate components of a CM intervention directly related to improved process of care or patient outcomes. Current efforts to structure CM to include face-to-face time and multiple diseases are discussed.

Change in health status and mortality as indicators of outcomes: comparison between the Medicare Advantage Program and the Veterans Health Administration

BACKGROUND

Comparing health outcomes with adequate methodology is central to performance assessments of health care systems. We compared the Medicare Advantage Program (MAP) and the Veterans Health Administration (VHA) with regard to changes in health status and mortality.

METHODS

We used the Death-Master-File for vital status and the Short-Form 36 to determine physical (PCS) and mental (MCS) health at baseline and at 2 years. We compared the probability of being alive with the same or better (than would be expected by chance) PCS (or MCS) at 2 years and mortality, while adjusting for case-mix. Given the geographic variations in MAP enrollment, we did a regional sub-analysis.

RESULTS

There were no significant differences in the probability of being alive with the same or better PCS except for the South (VHA 65.8% vs. MAP 62.5%, P = .0014). VHA patients had a slightly higher probability than MAP patients of being alive with the same or better MCS (71.8% vs. 70.1%, P = .002) but no significant regional variations. The hazard ratios for mortality in the MAP were higher than in the VHA across all regions.

CONCLUSION

With the use of appropriate methodology, we found small differences in 2-year health outcomes that favor the VHA.
