Persistent Orthopnea and the Prognosis of Patients in the Heart Failure Clinic

CONGESTIVE HEART FAILURE, Issue 4 2004
Luís Beck Da Silva MD
Heart failure (HF) is a public health problem with ever-growing costs. Signs such as jugular venous pressure and third heart sound have been associated with disease prognosis. Symptoms of heart failure are frequently subjective, and their real value is often overlooked. The authors aimed to assess the relationship between orthopnea and left ventricular ejection fraction (LVEF) and hospitalization rate in patients referred to the HF clinic. One hundred fifty-three new consecutive patients referred to the HF clinic from September 2001 to July 2002 were reviewed. Information about orthopnea was available at baseline and at a 6-month to 1-year follow-up. One hundred thirty-one patients had a baseline multigated radionuclide ventriculogram scan, and 68 patients had a follow-up multigated radionuclide ventriculogram scan available. The patients were divided into groups by presence of orthopnea and compared with respect to LVEF and hospitalization rate. Patients with or without orthopnea had similar LVEFs at baseline (32%±17% vs. 33%±15%, respectively; p=NS). However, patients who were orthopnea-free at the follow-up visit had a significant LVEF improvement whereas patients with ongoing orthopnea at follow-up had no LVEF improvement (11%±13% vs. ,1%±6%; p<0.001). Patients who presented with persistent orthopnea had a significantly higher rate of hospitalization (64% vs. 15.3%; p=0.0001). Persistent orthopnea in HF patients is associated with a significantly higher rate of hospitalization and with worsening or no improvement in LVEF. Patients with persistent orthopnea may require a more aggressive approach to improve their outcome. This result may help centers with limited access to LVEF measurements to better stratify HF patients' risk. [source]


Prevalence of Sleep Disordered Breathing in a Heart Failure Program

CONGESTIVE HEART FAILURE, Issue 5 2004
Robin J. Trupp MSN
Recent data show that a high percentage of patients with systolic left ventricular dysfunction have sleep-disordered breathing (SDB), contributing to the incidence of morbidity and mortality in heart failure. This study examines the prevalence of sleep disorders in stable heart failure patients regardless of ejection fraction. On three consecutive days in a heart failure clinic, all patients were asked to participate in a screening for SDB. This screening involved the placement of an outpatient device (ClearPath, Nexan, Inc., Alpharetta, GA), which collects thoracic impedance, oxyhemoglobin saturation, and 2-lead electrocardiogram data. Sixteen patients (42%) had moderate or severe SDB, and 22 patients (55%) had mild or no significant SDB. Fourteen of the 16 patients with moderate or severe SDB subsequently received treatment by confirming SDB and the continuous positive airway pressure in a sleep lab. Forty-two percent of patients with stable heart failure presenting to a heart failure clinic screened positive for SDB, despite receiving optimal standard of care. [source]


Fatigued Elderly Patients With Chronic Heart Failure

INTERNATIONAL JOURNAL OF NURSING TERMINOLOGIES AND CLASSIFICATION, Issue 2003

PURPOSE To compare descriptions of fatigue based on the NANDA characteristics from interviews with elderly people with congestive heart failure (CHF) and data recorded by nurses at a Swedish outpatient heart failure clinic. METHODS Patients were screened for moderate to severe CHF. A total of 158 patients were interviewed using a revised form of the Fatigue Interview Schedule (FIS) based on the NANDA characteristics. Of these patients, half (n= 79) were offered visits at a nurse-monitored heart failure clinic. Nursing documentation of fatigue at the heart failure clinic was reviewed based on the NANDA characteristics and compared with the content in the patient interviews. FINDINGS Tiredness was documented in 43 (75%) records and indicated in 36 patients based on patient scores on the FIS (X,= 5.5; range 1,9). The most frequently recorded observation related to fatigue was the symptom emotionally labile or irritable, followed by notes on lack of energy and decreased performance. Patients' descriptions of their fatigue were expressed as a decreased ability to perform and a perceived need for additional energy. Results indicated poor concordance in patients' descriptions and record content concerning fatigue. Whereas patients emphasized the physical characteristics of fatigue, nurses emphasised the emotional features. Decreased libido was linked to fatigue according to the patients but not according to the nurses' records. Whereas cognitive characteristics of fatigue occurred rarely in the records, they were more frequent in the patient interviews. DISCUSSION Symptoms such as irritability and accident-proneness may be seen as manifestations of the patients' experiencing the need for more energy or a feeling of decreased performance. These consequences of being fatigued, rather than the different dimensions of fatigue, seemed to have been easy for the nurses to observe and document. Earlier studies indicate that poor observation, medication, and diet in patients with heart failure might partly be explained by cognitive impairment. CONCLUSIONS Findings of this study highlight the need for nurses to pay attention to the experience of fatigue in patients who suffer from CHF, and to validate their observations with the patients own expressions. Using the patients' words and expressions and the diagnostic characteristics of fatigue in recording can support the nurses in developing both understanding of patients living with CHF and strategies to help patients cope with their restricted ability in daily life.

Quality and Outcomes of Heart Failure Care in Older Adults: Role of Multidisciplinary Disease-Management Programs

JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 9 2002
Ali Ahmed MD, FACP
PURPOSE: To determine whether the management of heart failure by specialized multidisciplinary heart failure disease-management programs was associated with improved outcomes. BACKGROUND: The advent of angiotensin-converting enzyme inhibitors, beta-blockers, and spironolactone has revolutionized the management of heart failure. Randomized double-blind studies have demonstrated survival benefits of these drugs in heart failure patients. Nevertheless, in spite of these advances, heart failure continues to be a syndrome of poor outcomes.1,4 There is also evidence that a significant portion of heart failure patients does not receive this evidence-based therapy that reduces morbidity and mortality.5,7 Various disease-management programs have been proposed and tested to improve the quality of heart failure care. Most of these programs are specialized multidisciplinary heart failure clinics lead by cardiologists or heart failure specialists and conducted by nurses or nurse practitioners. Similar to the Department of Veterans Affairs (VA) multidisciplinary geriatric assessment clinics, these clinics also use many other services, including pharmacists, dietitians, physical therapists, and social workers. Some of these programs also have an affiliated home health service. Several observation studies, using mostly pre- and postcomparison designs, have demonstrated the effectiveness of these programs in the process of care, resource use, healthcare costs, and clinical outcomes in patients with heart failure.8 Risk of hospitalization was reduced by 50% to 85% in six of the studies.8 Subsequently, several randomized trials were conducted to determine the effectiveness of these programs. The purpose of this systematic review was to determine the effectiveness of these programs on mortality and hospitalization rates of heart failure patients. METHODS: Published articles on human randomized trials involving specialized heart failure disease-management programs in all languages were searched using Medline from 1966 to 1999 and other online databases using the following terms and Medical Subject Headings: case management (exp); comprehensive health care (exp); disease management (exp); health services research (exp); home care services (exp); clinical protocols (exp); patient care planning (exp); quality of health care (exp); nurse led clinics; special clinics; and heart failure, congestive (exp). In addition, a manual search of the bibliographies of searched articles was performed to identify articles otherwise missed in the above search. Personal communications were made with three authors to obtain further data on their studies. Using a data abstraction tool, two of the investigators separately abstracted data from the selected articles. Data from the selected studies were combined using the DerSimonian and Laird random effects model and the Mantel-Haenszel-Peto fixed effects model. Meta-Analyst 0.998 software (J. Lau, New England Medical Center, Boston, MA) was used to determine risk ratios (RRs) with 95% confidence intervals (CIs) of mortality and hospitalization for patients receiving care through these specialized programs compared with those receiving usual care. The Cochran Q test was used to test heterogeneity among the studies, and sensitivity analyses were performed to examine the effect of various covariates, such as duration of intervention, and other characteristics of the disease-management programs. RESULTS: The original search resulted in 416 published articles, of which 35 met preliminary selection criteria. Of these, 11 were randomized trials and were selected for the meta-analysis. Studies that were not randomized trials, did not involve heart failure patients or disease-management programs, or had missing outcomes were excluded. Of the 11 studies selected, nine involved specialized follow-up using multidisciplinary teams and the remaining two involved follow-up by primary care physicians and telephone. These studies involved 1,937 heart failure patients with a mean age of 74. The follow-up period ranged from no follow-up (one study) to 1 year (one study). Patients receiving care from specialized heart failure disease-management programs had a 13% lower risk of hospitalization than those receiving usual care (summary RR = 0.87; 95% CI = 0.79,0.96), but the Cochran Q test demonstrated significant heterogeneity among the studies (P = .003). Subgroup analysis of the nine studies using specialized follow-up by a multidisciplinary team showed similar results (summary RR = 0.77, 95% CI = 0.68,0.86; test of heterogeneity, P> .50). Seven of the nine studies did not show any significant association between intervention and reduced hospitalization, but the two studies that used follow up by primary care physicians and telephone failed to show any significant reduction in hospitalization (summary RR = 0.94, 95% CI = 0.75,1.19). In fact, one of the studies demonstrated a higher risk of hospitalization for patients receiving intervention (RR = 1.26, 95% CI = 1.04,1.52). Of the 11 studies, only six reported mortality as an outcome. None of these studies found any association between intervention and mortality (summary RR = 1.15, 95% CI = 0.96,1.37; test of heterogeneity, P> .15). Five of the studies used quality of life or functional status as outcomes, and, of them, only one demonstrated significant positive association. The results of the sensitivity analyses were negative for any significant association with duration of intervention or follow-up or year of study. Eight studies performed cost analyses and seven demonstrated cost-effectiveness of the intervention. CONCLUSIONS: The authors concluded that specialized disease-management programs were cost-effective, and heart failure patients cared for by these programs were more likely to undergo fewer hospitalizations, but the study did not provide any conclusive association between these programs and quality of care or mortality. The authors recommend that disease-management programs involve patient education and specialized follow-up by a multidisciplinary team including home health care. [source]
