Evaluating implementation strategies to support documentation of veterans' care preferences.

OBJECTIVE: To evaluate the effectiveness of feedback reports and feedback reports + external facilitation on completion of life-sustaining treatment (LST) note the template and durable medical orders. This quality improvement program supported the national roll-out of the Veterans Health Administration (VA) LST Decisions Initiative (LSTDI), which aims to ensure that seriously-ill veterans have care goals and LST decisions elicited and documented. DATA SOURCES: Primary data from national databases for VA nursing homes (called Community Living Centers [CLCs]) from 2018 to 2020. STUDY DESIGN: In one project, we distributed monthly feedback reports summarizing LST template completion rates to 12 sites as the sole implementation strategy. In the second involving five sites, we distributed similar feedback reports and provided robust external facilitation, which included coaching, education, and learning collaboratives. For each project, principal component analyses matched intervention to comparison sites, and interrupted time series/segmented regression analyses evaluated the differences in LSTDI template completion rates between intervention and comparison sites. DATA COLLECTION METHODS: Data were extracted from national databases in addition to interviews and surveys in a mixed-methods process evaluation. PRINCIPAL FINDINGS: LSTDI template completion rose from 0% to about 80% throughout the study period in both projects' intervention and comparison CLCs. There were small but statistically significant differences for feedback reports alone (comparison sites performed better, coefficient estimate 3.48, standard error 0.99 for the difference between groups in change in trend) and feedback reports + external facilitation (intervention sites performed better, coefficient estimate -2.38, standard error 0.72). CONCLUSIONS: Feedback reports + external facilitation was associated with a small but statistically significant improvement in outcomes compared with comparison sites. The large increases in completion rates are likely due to the well-planned national roll-out of the LSTDI. This finding suggests that when dissemination and support for widespread implementation are present and system-mandated, significant enhancements in the adoption of evidence-based practices may require more intensive support.

Pain Management in the Post-acute and Long-Term Care Setting: A Clinical Practice Guideline (CPG) from the Society for Post-acute and Long-Term Care Medicine (AMDA).

This comprehensive clinical guideline addresses pain issues that arise in care of patients commonly seen in post-acute and long-term care settings, including very old and frail individuals with multiple chronic medical and psychiatric conditions, short-stay patients needing posthospitalization care, and younger adults with chronic diseases and disabilities. Its sections proceed along the steps of the clinical process, and hence include pain definition, recognition, and assessment; diagnosis and cause-effect analysis; identification of care objectives; selection of interventions from the wide range or potential options, including a discussion of appropriate and rational use of opioids; and monitoring of the progress and outcomes of management decisions. The guideline emphasizes treating pain in the context of each patient's overall condition and not as a separate issue. It includes discussion of such challenging issues as responsibilities and capabilities of the staff and practitioners, what to do when patients persistently experience high pain levels despite substantial doses of analgesics, and how best to address the expectations of relevant regulations and surveyor guidelines. By including numerous hypertext links within the document, the CPG facilitates finding related information in different sections as well as external references and resources that provide additional support.

Psychometric evaluation of the Hopkins Rehabilitation Engagement Rating Scale in postacute physical therapy services.

PURPOSE/OBJECTIVE: Evaluate the reliability and validity of the Hopkins Rehabilitation Engagement Scale (HRERS) in a postacute rehabilitation sample. We hypothesized that HRERS items would comprise a single factor, and would demonstrate adequate internal consistency and temporal stability, and significant relationships with key constructs. Research Method and Design: Retrospective medical record review between 2016 and 2017 of older veterans (N = 107) admitted to a community living center postacute care (CLC-PAC) rehabilitation hospital unit to address targeted physical therapy rehabilitation goals. Inclusion criteria included availability of two HRERS administrations at Time 1 (admission) and Time 2 (approximately one-month follow-up or physical therapist/CLC-PAC discharge). RESULTS: Across timepoints, HRERS items reflect a single factor of engagement, and the scale has good internal consistency at admission (Time 1, α = .759) and follow-up (Time 2, α = .877). The temporal stability of HRERS across ratings was r = .56 (p < .001). Increased pain rating (r = -.309, p < .01) and depressive symptoms (-.287, p < .01) at admission correlates with subsequent physical therapist (PT) engagement (HRERS Time 2). Low admission PT engagement correlates with less frequent PT attendance (r = -.242, p < .01) and greater number of consults placed during the CLC stay (r = -.222, p < .05). CONCLUSIONS/IMPLICATIONS: HRERS is a reliable and valid measure of PT engagement in older CLC-PAC Veterans. Findings support the administration of the HRERS at more than one timepoint during rehabilitation to inform interventions targeting select behavioral health factors such as pain and depression.

Team VA Video Connect (VVC) to optimize mobility and physical activity in post-hospital discharge older veterans: baseline assessment.

BACKGROUND: Telehealth is increasingly used for rehabilitation and exercise but few studies include older adult participants with comorbidities and impairment, particularly cognitive. Using Veterans Administration Video Connect (VVC), the aim of the present study is to present the screening, recruitment, baseline assessment, and initial telehealth utilization of post-hospital discharge Veterans in a VVC home-telehealth based program to enhance mobility and physical activity. METHODS: Older adult Veterans (n = 45, mean age 73), recently discharged from the hospital with physical therapy goals, were VVC-assessed in self-report and performance-based measures, using test adaptations as necessary, by a clinical pharmacy specialist and social worker team. RESULTS: Basic and instrumental ADL disabilities were common as were low mobility (Short Portable Performance Battery) and physical activity levels (measured by actigraphy). Half had Montreal Cognitive Assessment (MoCA) scores in the mild cognitive impairment range (< 24). Over 2/3 of the participants used VA-supplied tablets. While half of the Veterans were fully successful in VVC, 1/3 of these and an additional group with at least one failed connection requested in-person visits for assistance. One-quarter had no VVC success and sought help for tablet troubleshooting, and half of these eventually "gave up" trying to connect; difficulty with using the computer and physical impairment (particularly dexterity) were described prominently in this group. On the other hand, Veterans with at least mild cognitive impairment (based on MoCA scores) were present in all connectivity groups and most of these used caregiver support to facilitate VVC. CONCLUSIONS: Disabled older post-hospital discharged Veterans with physical therapy goals can be VVC-assessed and enrolled into a mobility/physical activity intervention. A substantial proportion required technical support, including in-person support for many. Yet, VVC seems feasible in those with mild cognitive impairment, assuming the presence of an able caregiver. Modifications of assessment tools were needed for the VVC interface, and while appearing feasible, will require further study. TRIAL REGISTRATION: ClinicalTrials.gov NCT04045054 05/08/2019.

Family members' experience improves with care preference documentation in home based primary care.

BACKGROUND: The Veterans Health Administration (VA) implemented the comprehensive life-sustaining treatment (LST) Decisions Initiative to provide training and standardize documentation of goals of care and LST preferences for seriously ill Veterans to improve end-of-life (EOL) outcomes. LST documentation is expected for all Home-Based Primary Care (HBPC) Veterans because they are at high risk of hospitalization and mortality. METHODS: A retrospective, cross-sectional analysis compared associations between Bereaved Family Survey (BFS) EOL care ratings and LST documentation. Participants were Veterans who died August 1, 2018 through September 30, 2019 in one of 55 VA HBPC programs. Regression modeling generated odds for key BFS outcomes. LST template completion rate was plotted by month to understand the interaction between time, LST completion rate, and EOL care family ratings. RESULTS: LST preferences were documented for 39% of HBPC Veterans. Family members rated overall EOL care as excellent for 53% of Veterans but significant divergence in BFS ratings occurred during the last 7 months of the study with 60% of family members of LST completers rating care as excellent compared with 48% for Veterans lacking LST documentation (p = 0.003). The adjusted odds of rating overall care in the final month of life as excellent was higher among those with a completed LST template (1.64 95% CI 1.19, 2.26). CONCLUSIONS: Higher rates of LST documentation were associated with more favorable ratings of EOL but not in initial months following implementation of the comprehensive initiative; however, LST documentation rates were lower than expected among HBPC Veterans. Following an initial period of implementation of a comprehensive national initiative to promote Veteran choice about care during serious illness, documented LST preferences were associated with better family ratings of EOL care. HBPC clinicians may improve the bereaved family experience by using LSDTI tools and training to elicit and document preferences.

Cognitive status as a robust predictor of repeat falls in older Veterans in post-acute care.

BACKGROUND: While repeat falls are common in post-acute care (PAC), risk factors have not been fully elucidated. AIMS: The objective of thids study is to evaluate the contribution of cognitive function to repeat falls in older PAC Veterans. METHODS: Data were collected from medical records for 91 single and 30 repeat fallers over 5 consecutive years (2011-2016). RESULTS: After controlling for demographic and medical factors, lower Mini-Mental State Exam (MMSE) score was associated with increased odds of repeat falls. MMSE scores below 20 (with age held constant at the mean) were associated with a greater than 50% chance of a repeat fall (compared to 24.7% base rate). Admission for a neurologic reason further increased risk. DISCUSSION: PAC Veterans who experience a fall have an increased risk of repeat falls with concomitant cognitive dysfunction and/or admission for neurologic reasons. CONCLUSIONS: Results support tailoring multi-component interventions for those with cognitive dysfunction utilizing standardized mental status screening upon admission.

Honoring Veterans' Preferences: The Association Between Comfort Care Goals and Care Received at the End of Life.

CONTEXT: As part of its Life-Sustaining Treatment (LST) Decisions Initiative, the Veterans Health Administration (VA) in January 2017 began requiring electronic documentation of goals of care and preferences for Veterans with serious illness and at high risk for life-threatening events. OBJECTIVES: To evaluate whether goals of "to be comfortable" were associated with greater palliative care (PC) use and lesser acute care use. METHODS: We identified Veterans with VA inpatient or nursing home stays overlapping July 2018-January 2019, with LST templates documented by January 31, 2019, and who died by April 30, 2019 (N = 18,163). From template documentation, we identified a "to be comfortable" goal. Using VA and Medicare data, we determined PC use (consultations and hospice) and hospital, intensive care unit, and emergency department use 7 and 30 days before death. Multivariate logistic regression examined the associations of interest. RESULTS: Sixty-four percent of the 18,163 Veterans had comfort-care goals; 80% with comfort care goals received hospice and 57% PC consultations (versus 57% and 46%, respectively, for decedents without comfort-care goals). In adjusted analyses, comfort care documented on the LST template prior to death was associated with significantly lower odds of hospital, intensive care unit, and emergency department use near the end of life. In the last 30 days of life, Veterans with a comfort care goal had 44% lower odds (adjusted odds ratio 0.57; 95% CI: 0.51, 0.63) of being hospitalized. CONCLUSION: Findings support the VA's commitment to honoring of Veterans' preferences post introduction of its Life Sustaining Treatment Decisions Initiative.

Visual process maps to support implementation efforts: a case example.

BACKGROUND: Process mapping is often used in quality improvement work to examine current processes and workflow and to identify areas to intervene to improve quality. Our objective in this paper is to describe process maps as a visual means of understanding modifiable behaviors and activities, in this case example to ensure that goals of care conversations are part of admitting a veteran in long-term care settings. METHODS: We completed site visits to 6 VA nursing homes and reviewed their current admission processes. We conducted interviews to document behaviors and activities that occur when a veteran is referred to a long-term care setting, during admission, and during mandatory VA reassessments. We created visualizations of the data using process mapping approaches. Process maps for each site were created to document the admission activities for each VA nursing home and were reviewed by the research team to identify consistencies across sites and to identify potential opportunities for implementing goals of care conversations. RESULTS: We identified five consistent behaviors that take place when a veteran is referred and admitted in long-term care. These behaviors are assessing, discussing, decision-making, documenting, and re-assessing. CONCLUSIONS: Based on the process maps, it seems feasible that the LST note and order template could be completed along with other routine assessment processes. However, this will require more robust multi-disciplinary collaboration among both prescribing and non-prescribing health care providers. Completing the LST template during the current admission process would increase the likelihood that the template is completed in a timely manner, potentially alleviate the perceived time burden, and help with the provision of veteran-centered care.

Designing clinical practice feedback reports: three steps illustrated in Veterans Health Affairs long-term care facilities and programs.

BACKGROUND: User-centered design (UCD) methods are well-established techniques for creating useful artifacts, but few studies illustrate their application to clinical feedback reports. When used as an implementation strategy, the content of feedback reports depends on a foundational audit process involving performance measures and data, but these important relationships have not been adequately described. Better guidance on UCD methods for designing feedback reports is needed. Our objective is to describe the feedback report design method for refining the content of prototype reports. METHODS: We propose a three-step feedback report design method (refinement of measures, data, and display). The three steps follow dependencies such that refinement of measures can require changes to data, which in turn may require changes to the display. We believe this method can be used effectively with a broad range of UCD techniques. RESULTS: We illustrate the three-step method as used in implementation of goals of care conversations in long-term care settings in the U.S. Veterans Health Administration. Using iterative usability testing, feedback report content evolved over cycles of the three steps. Following the steps in the proposed method through 12 iterations with 13 participants, we improved the usability of the feedback reports. CONCLUSIONS: UCD methods can improve feedback report content through an iterative process. When designing feedback reports, refining measures, data, and display may enable report designers to improve the user centeredness of feedback reports.

Influence of Cognition on Length of Stay and Rehospitalization in Older Veterans Admitted for Post-Acute Care.

OBJECTIVES: Evaluate the relative contribution of cognitive test performance to post-acute care (PAC) length of stay (LOS) and rehospitalization while controlling for key demographic, medical, and functional outcomes. METHODS: Retrospective medical record review of 160 older Veterans, including cognitive test performance (Addenbrooke's Cognitive Examination-Revised [ACE-R]), on admission to a Veterans Administration Hospital Community Living Center (CLC) PAC. RESULTS: Individuals with impaired scores on the ACE-R had a longer LOS (10 median days longer; U = 2,547.00, p = .028). Of those rehospitalized, 71.4% (n = 20) screened positive for cognitive impairment. Key medical factors explained the largest amount of variance in CLC-PAC LOS (29.8%), followed by admission ADL (activities of daily living) dependency (4.6%) and ACE-R total score (3.30%). DISCUSSION: Cognitive screening should be considered on PAC admission, with impairment on ACE-R predicting geriatric rehabilitation outcomes such as risk of increased LOS and rehospitalization.

Self-Reported Health and Safety Awareness Improves Prediction of Level of Care Needs in Veterans Discharged From a Postacute Unit.

OBJECTIVES: To evaluate the differential value of a self-reported health and safety awareness measure relative to other medical, psychosocial, and cognitive factors in predicting level of care (LOC) needs after hospital discharge. DESIGN: Retrospective medical record review. SETTING: Community living center postacute care (CLC-PAC) unit at a Veterans Affairs hospital. PARTICIPANTS: A total of 175 veterans admitted to the Veterans Affairs hospital or directly to the CLC-PAC from home. METHODS: Cognitive status was assessed with the Mini-Mental State Examination, Digit Span Backward subtest, Trail Making Test (Part B), and Hopkins Verbal Learning Test-Revised. Self-report of health and safety awareness was measured with the Independent Living Scales Health and Safety (ILS-HS) subscale. Additional demographic and admission-related variables were coded, along with medical comorbidity, with the Charlson Comorbidity Index and depression using the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision Depression Checklist. MAIN OUTCOME MEASUREMENTS: Increased level of care was collected from social work and occupational therapy notes and defined as increased assistance with activities of daily living or nursing home placement comparing prehospitalization with CLC-PAC discharge. RESULTS: A total of 19% (n = 34) of residents required increased LOC on CLC-PAC discharge. The ILS-HS was a significant predictor of increased LOC above and beyond age and Mini Mental Status Examination score; for each standard deviation decrease in ILS-HS, there was an increased likelihood of greater LOC (odds ratio 0. 54, 95% confidence interval 0.35-0.83). Other neuropsychological tests (memory, executive functioning) did not significantly improve the model. CONCLUSIONS: The inclusion of the ILS-HS to a standard cognitive screen (Mini Mental Status Examination) can improve prediction of increased LOC. Although select aspects of memory and executive functioning independently contribute to increased LOC prediction, the ILS-HS likely measures a unique aspect of cognitive functioning that may be specific to discharge planning needs in CLC-PAC residents. LEVEL OF EVIDENCE: II.

Comparing Catheter-Associated Urinary Tract Infection Prevention Programs Between Veterans Affairs Nursing Homes and Non-Veterans Affairs Nursing Homes.

OBJECTIVE The impact of healthcare system integration on infection prevention programs is unknown. Using catheter-associated urinary tract infection (CAUTI) prevention as an example, we hypothesize that US Department of Veterans Affairs (VA) nursing homes have a more robust infection prevention infrastructure due to integration and centralization compared with non-VA nursing homes. SETTING VA and non-VA nursing homes participating in the AHRQ Safety Program for Long-Term Care collaborative. METHODS Nursing homes provided baseline information about their infection prevention programs to assess strengths and gaps related to CAUTI prevention via a needs assessment questionnaire. RESULTS A total of 353 of 494 nursing homes from 41 states (71%; 47 VA and 306 non-VA facilities) responded. VA nursing homes reported more hours per week devoted to infection prevention-related activities (31 vs 12 hours; P<.001) and were more likely to have committees that reviewed healthcare-associated infections. Compared with non-VA facilities, a higher percentage of VA nursing homes reported tracking CAUTI rates (94% vs 66%; P<.001), sharing CAUTI data with leadership (94% vs 70%; P=.014) and with nursing personnel (85% vs 56%, P=.003). However, fewer VA nursing homes reported having policies for appropriate catheter use (64% vs 81%; P=.004) and catheter insertion (83% vs 94%; P=.004). CONCLUSIONS Among nursing homes participating in an AHRQ-funded collaborative, VA and non-VA nursing homes differed in their approach to CAUTI prevention. Best practices from both settings should be applied universally to create an optimal infection prevention program within emerging integrated healthcare systems.

Implementing goals of care conversations with veterans in VA long-term care setting: a mixed methods protocol.

BACKGROUND: The program "Implementing Goals of Care Conversations with Veterans in VA LTC Settings" is proposed in partnership with the US Veterans Health Administration (VA) National Center for Ethics in Health Care and the Geriatrics and Extended Care Program Offices, together with the VA Office of Nursing Services. The three projects in this program are designed to support a new system-wide mandate requiring providers to conduct and systematically record conversations with veterans about their preferences for care, particularly life-sustaining treatments. These treatments include cardiac resuscitation, mechanical ventilation, and other forms of life support. However, veteran preferences for care go beyond whether or not they receive life-sustaining treatments to include issues such as whether or not they want to be hospitalized if they are acutely ill, and what kinds of comfort care they would like to receive. METHODS: Three projects, all focused on improving the provision of veteran-centered care, are proposed. The projects will be conducted in Community Living Centers (VA-owned nursing homes) and VA Home-Based Primary Care programs in five regional networks in the Veterans Health Administration. In all the projects, we will use data from context and barrier and facilitator assessments to design feedback reports for staff to help them understand how well they are meeting the requirement to have conversations with veterans about their preferences and to document them appropriately. We will also use learning collaboratives-meetings in which staff teams come together and problem-solve issues they encounter in how to get veterans' preferences expressed and documented, and acted on-to support action planning to improve performance. DISCUSSION: We will use data over time to track implementation success, measured as the proportions of veterans in Community Living Centers (CLCs) and Home-Based Primary Care (HBPC) who have a documented goals of care conversation soon after admission. We will work with our operational partners to spread approaches that work throughout the Veterans Health Administration.

Heart failure: clinical problem and management issues.

Heart failure (HF) often presents as dyspnea either with exertion and/or recumbency. Patients also experience dependent swelling and fatigue. Measurement of the left ventricular ejection fraction (LVEF) identifies HF patients who may respond to pharmacologic therapy and/or electrophysiologic device implantation. Angiotension converting enzyme inhibitors, beta blockers, and aldosterone inhibitors can significantly lower the mortality and morbidity of HF in patients with an LVEF less than 35%. Cardiac defibrillators and biventricular pacemakers can also improve outcomes in selected patients with a decreased LVEF. The authors provide a guide for therapeutic decisions based on the inclusion criteria of the major clinical trials.

Assessing health status differences between Veterans Affairs home-based primary care and state Medicaid Waiver Program clients.

OBJECTIVES: Comprehensive health care for older adults is complex, involving multiple comorbidities and functional impairments of varying degrees and numbers. In response to this complexity and associated barriers to care, home-based care models have become prevalent. The home-based primary care (HBPC) model, based at a Michigan Department of Veterans Affairs Medical Center, and the Michigan Waiver Program (MWP) that includes home-based care are 2 of these. Although both models are formatted to address barriers to effective and efficient health care, there are differences in disease prevalence and functional performance between groups. The objective of this study was to explore the differences between the 2 groups, to shed some light on potential trends that could suggest areas for resource allocation by service providers. DESIGN: Using a retrospective analysis of data collected using the interRAI-home care, we examined a cross-sectional representation of clients enrolled in HBPC and MWP in 2008. PARTICIPANTS: The HBPC sample had 89 participants. The MWP database contained 9324 participants from across the State of Michigan and were weighted to be comparable to the HBPC population in sex and age, and to simulate the HBPC sample size. RESULTS: Veterans were more independent in basic activities of daily living performance, but there was no difference in the rate of reported falls between the 2 groups. Veterans had more pain and a higher prevalence of coronary artery disease (z = 7.0; P < .001), Chronic obstructive pulmonary disease (z = 3.9; P < .001), and cancer (z = 8.5; P < .001). There was no statistically significant difference between the 2 groups in terms of the prevalence of geriatric syndromes. Scores on subscales of the interRAI-home care indicated a lower risk of serious health decline and adverse outcomes for MWP compared with HBPC clients (1.4 ± 1.1 vs 0.9 ± 0.1; z = 2.5; P = .012). Veterans receiving home-based care through the Veterans Affairs Medical Center were more burdened by chronic disease and had higher degrees of loneliness than their MWP counterparts- factors, which may increase their likelihood of hospitalizations. MWP participants had more cases of cerebrovascular accident (z = 2.1; P = .039), as well as a higher rate of diagnosed dementias (z = 2.7; P = .006). Though not different, stress among caregivers in both groups, and depression in clients of both groups were substantial. Overall, sleep, pain, coronary artery disease, chronic obstructive pulmonary disease, and cancer are significant issues for Veteran clients, and clients treated through MWP home-care in Michigan have higher than national average rates of dementias, diabetes, hypertension, and coronary artery disease. CONCLUSION: With expanded home care models of service on the horizon, comparisons such as the one presented here could identify more efficient and effective service, with potential for improved client health outcomes.

Pharmacologic management of heart failure caused by systolic dysfunction.

Heart failure caused by systolic dysfunction affects more than 5 million adults in the United States and is a common source of outpatient visits to primary care physicians. Mortality rates are high, yet a number of pharmacologic interventions may improve outcomes. Other interventions, including patient education, counseling, and regular self-monitoring, are critical, but are beyond the scope of this article. Angiotensin-converting enzyme inhibitors and beta blockers reduce mortality and should be administered to all patients unless contraindicated. Diuretics are indicated for symptomatic patients as needed for volume overload. Aldosterone antagonists and direct-acting vasodilators, such as isosorbide dinitrate and hydralazine, may improve mortality in selected patients. Angiotensin receptor blockers can be used as an alternative therapy for patients intolerant of angiotensin-converting enzyme inhibitors and in some patients who are persistently symptomatic. Digoxin may improve symptoms and is helpful for persons with concomitant atrial fibrillation, but it does not reduce cardiovascular or all-cause mortality. Serum digoxin levels should not exceed 1.0 ng per mL (1.3 nmol per L), especially in women.

Coronary artery bypass grafting in octogenarians: clinical and economic outcomes at community-based healthcare facilities.

BACKGROUND: Results of recent studies from high-volume academic centers suggest that coronary artery bypass grafting (CABG) is becoming safer to perform in octogenarians. Similar data from community-based facilities do not exist. OBJECTIVE: To assess the clinical and economic outcomes of nonemergency CABG in 338 octogenarians at 27 community-based facilities across the United States. STUDY DESIGN: Retrospective cohort analysis. PATIENTS AND METHODS: Multivariate analyses were used to compare (1) in-hospital mortality rates, (2) rates of discharge to extended-care facilities, (3) lengths of stay, and (4) in-hospital costs between octogenarians and younger patients. RESULTS: Of 338 patients 80 years or older, the in-hospital mortality rate was higher (4.7% vs 2.1%; P = .002), the rate of discharge to extended-care facilities was greater (24.9% vs 4.8%; P < .001), the length of stay was longer (9.6 vs 7.9 days; P < .001), and in-hospital costs were higher ($20,188 vs $18,196; P < .001) compared with patients younger than 80 years. After adjusting for several covariates, we found that octogenarians were at significantly greater risk of experiencing in-hospital deaths (odds ratio, 4.6; P = .001), of being discharged to extended-care facilities (odds ratio, 28.4; P < .001), and of having longer lengths of stay (difference, 0.7 days; P = .002) than were patients aged 50 to 59 years. CONCLUSION: At these 27 community-based facilities, the in-hospital mortality for nonemergency CABG in octogenarians was 4.7%; however, nearly 25% of surviving octogenarians were discharged to extended-care facilities.

Sympathetic activity and the heterogenous blood pressure response to exercise training in hypertensives.

To test whether changes in sympathetic nervous system (SNS) activity or insulin sensitivity contribute to the heterogeneous blood pressure response to aerobic exercise training, we used compartmental analysis of [3H]norepinephrine kinetics to determine the extravascular norepinephrine release rate (NE2) as an index of systemic SNS activity and determined the insulin sensitivity index (S(I)) by an intravenous glucose tolerance test, before and after 6 mo of aerobic exercise training, in 30 (63 +/- 7 yr) hypertensive subjects. Maximal O2 consumption increased from 18.4 +/- 0.7 to 20.8 +/- 0.7 ml x kg(-1) x min(-1) (P = 0.02). The average mean arterial blood pressure (MABP) did not change (114 +/- 2 vs. 114 +/- 2 mmHg); however, there was a wide range of responses (-19 to +17 mmHg). The average NE2 did not change significantly (2.11 +/- 0.15 vs. 1.99 +/- 0.13 microg x min(-1) x m(-2)), but there was a significant positive linear relationship between the change in NE2 and the change in MABP (r = 0.38, P = 0.04). S(I) increased from 2.81 +/- 0.37 to 3.71 +/- 0.42 microU x 10(-4) x min(-1) x ml(-1) (P = 0.004). The relationship between the change in S(I) and the change in MABP was not statistically significant (r = -0.03, P = 0.89). When the changes in maximal O2 consumption, percent body fat, NE2, and S(I) were considered as predictors of the change in MABP, only NE2 was a significant independent predictor. Thus suppression of SNS activity may play a role in the reduction in MABP and account for a portion of the heterogeneity of the MABP response to aerobic exercise training in older hypertensive subjects.
