The economic burden of chronic obstructive pulmonary disease (COPD) in a U.S. Medicare population.

RATIONALE: Although the economic burden of COPD has gained attention in recent years, data on the costs of COPD among U.S. Medicare beneficiaries are lacking. METHODS: This study used administrative claims and eligibility records from a large U.S. multi-state Medicare managed care database. Study patients were 65+ years of age with paid claims during 2004. The COPD cohort comprised patients with 1+ inpatient/ER claims or 2+ outpatient claims (>30 days apart) for COPD (ICD-9-CM codes 491.xx, 492.x, 496). The comparison cohort included patients without COPD matched 3:1 to the COPD cohort on age, sex, enrollment months, and Medicare plan. Excess costs of COPD were estimated as the difference in overall health plan payments between the two cohorts during 2004. Attributable costs were calculated using medical claims with listed diagnoses of COPD or other respiratory-related conditions and pharmacy claims for respiratory medications. RESULTS: A total of 8370 patients were included in the COPD cohort and were matched to 25,110 comparison cohort patients. For both groups, mean (SD) age was 78 (8) years, 54% were female, and duration of eligibility was 11 (2) months. COPD patients were more likely to utilize healthcare services and had excess total healthcare costs about $20,500 higher (P<0.0001) than the comparison cohort. Comorbidities were high in the COPD cohort, accounting for 46% of the observed excess cost. The attributable cost of COPD averaged about $6,300; other respiratory-related costs averaged about $4,400. CONCLUSION: In this U.S. Medicare managed care population, COPD posed a substantial burden in terms of both respiratory-related and total healthcare costs. A comparison of these cost-of-illness estimates to those for elderly COPD patients in other countries would be of great interest, given the increasing age of populations in most Western countries.

Neglect assessment in urban emergency departments and confirmation by an expert clinical team.

BACKGROUND: Elder neglect accounts for over 70% of all adult protective services reports in the nation annually, and it has been estimated that there are over 70,000 new cases each year. The purpose of this study was to conduct elder neglect research in the emergency department (ED), using a dyadic vulnerability/risk-profiling framework for elder neglect. METHODS: Patients were recruited through four EDs in New York and Tampa from the beginning of February 2001 through the end of September 2003. Demographics, a Mini-Mental Status Examination score, and an initial elder assessment screen were collected. The diagnosis of neglect was then made by a Neglect Assessment Team (NAT) comprising a nurse, physician, and social worker, with extensive clinical experience in elder neglect. RESULTS: Of the 3664 ED screens of adults 70 years and older, 405 (11%) met the inclusion criteria and agreed to participate. Neglect was diagnosed by the NAT in 86 of the 405 cases reviewed. Demographic differences between neglect versus no neglect cases were examined using Fisher's exact test, and differences emerged between the 2 groups. CONCLUSION: This study documents the underreporting of cases of neglect as evidenced by differences in diagnoses by screeners versus experts. The research assistants screened positive for neglect in 5% (N=22) of the 405 cases. The NAT made the diagnosis of neglect in 22% (86/389) of the cases. This markedly different rate of neglect may mean that ED screens are important but may underestimate the true number of cases. Conversely, an NAT may make the diagnosis of neglect in an older adult more often given a higher sensitivity and a more robust knowledge base of the problem.

Dyadic vulnerability and risk profiling for elder neglect.

PURPOSE: Neglect of older adults accounts for 60% to 70% of all elder-mistreatment reports made to adult protective services. The purpose of this article is to report data from research, using a risk-and-vulnerability model, that captures the independent contributions of both the elder and the caregiver as they relate to the outcome of neglect. METHODS: Between February 2001 and September 2003, older adults were screened and recruited through four emergency departments in New York and Tampa. The diagnosis of neglect was made by an expert neglect-assessment team. Elders and their caregivers were then scheduled for separate face-to-face interviews after discharge. RESULTS: Constructs within the risk-and-vulnerability model were examined for scale-score significance based on the outcome diagnosis of neglect. In the risk domain, caregivers' functional status, childhood trauma, and personality were statistically significant. In the vulnerability domain, the elders' cognitive status, functional status, depression, social support, childhood trauma, and personality were significant. IMPLICATIONS: Findings from this study underscore the value of interdisciplinary assessment teams in emergency departments for screening elder neglect, with attention given to risk factors related to the caregiver and elder vulnerability factors, including reports of childhood trauma. The risk-and-vulnerability model may provide a link between the caregiving and neglect research. Data should be collected independently from both members of the elder-caregiver dyad in order for clinicians to understand factors related to elders who receive the diagnosis of neglect from interdisciplinary teams.

Using PDAs for data collection.

Advances in handheld computer technology are making data collection faster, easier, and more accurate. In this article, the use of personal digital assistants (PDAs) to collect data for a study on elder neglect is described and evaluated. Methods for integrating this technology into a research study are discussed as are suggestions for increasing the performance of data collectors using these devices. The authors offer some practical solutions for researchers and clinicians planning to use PDAs in their research.

Elder mistreatment in women.

Elder mistreatment is a serious syndrome that affects more than 1.5 million older Americans every year. Actions such as abuse, neglect, exploitation, and abandonment by caregivers, relatives, friends, or acquaintances can have devastating sequelae for the elderly. Such actions may be intentional or unintentional, but the detrimental outcomes for older individuals can destroy the elder's quality of life and health. A lack of empirical research addresses gender differences in elder mistreatment. There is also confusion and debate over what constitutes elder mistreatment in older women versus what is domestic violence that has continued into later life. Professional nurses need to include both types of screening for their older female patients in order to address both types of family violence.

Progress in elder abuse screening and assessment instruments.

The responsibility of identifying elder mistreatment (EM) often falls on the healthcare professional. Many different screening and assessment instruments have been developed to aid healthcare professionals in making determinations about EM. The purpose of this article is to review existing EM screening and assessment instruments to examine progress in this field. The value and limitations of these instruments with regard to their use in different clinical and healthcare settings are discussed. The settings in which EM screening and assessment are conducted are also considered. The authors conclude that there is much to be done in terms of achieving consensus on what constitutes an appropriate screen or assessment instrument for detecting EM. Effort must be focused on instruments that can be used for brief, rapid screenings and those that can be used for more-detailed diagnostic assessments.

Themes from a grounded theory analysis of elder neglect assessment by experts.

PURPOSE: This paper describes one program that has developed a screening procedure for assessing elder mistreatment, with a special focus on elder neglect. The aim is to understand how expert neglect assessment teams process and diagnose complex geriatric cases referred for suspected elder neglect. What are the key themes that must be understood in order to determine if neglect should be suspected and confirmed? DESIGN AND METHODS: Transcripts of audio recordings of neglect assessment team meetings were analyzed by using grounded theory analysis. RESULTS: Four major themes emerged from the analysis of the transcripts. These themes were understanding the underlying health status of the elder and caregiver, understanding the socioeconomic and life circumstances of the dyad, credibility of data collected by others, and the consequences of the assessment outcome. IMPLICATIONS: These findings offer insight into the development of future clinical screening and assessment procedures used to make diagnoses about elder neglect, as well as the guidelines that govern neglect assessment. Understanding not only the high-risk signs and symptoms but also the context and consequences of neglect is critical. Future screening and assessment procedures should be developed with these data in mind.
