Reasons for seeking acute care in chronic heart failure

Predictors of delay in heart failure patients and consequences for outcomes

Persons with heart failure (HF) symptoms delay up to 7 days before seeking treatment. Delay can result in worse symptoms and potentially impact outcomes. The purpose of this review was to describe predictors and outcomes of delay in HF patients. Demographic factors, increased symptom number, social factors, greater HF knowledge, lower anxiety, and depression predicted increased delay. HF patients had difficulty recognizing and interpreting symptoms of HF. Results are conflicting related to symptom pattern, time of care seeking, and history of HF as predictors of delay. The only outcome predicted by delay was length of stay with those delaying longer reporting longer lengths of stay. Future research related to delay should include theoretical frameworks and larger, more ethnically diverse samples from multiple sites and link delay to outcomes. Valid and reliable instruments are needed to measure delay and related factors. HF education should include supportive others.

Health Status and Self-care Outcomes After an Education-Support Intervention for People With Chronic Heart Failure

BACKGROUND

The rising cost of hospitalizations for heart failure (HF) care mandates intervention models to address education for self-care success. The effectiveness of memory enhancement strategies to improve self-care and learning needs further examination.

OBJECTIVE

The objective of this study was to examine the effects of an education-support intervention delivered in the home setting, using strategies to improve health status and self-care in adults/older adults with class I to III HF. Our secondary purpose was to explore participants' subjective perceptions of the intervention.

METHODS

This study used a randomized, 2-group design. Fifty people were enrolled for 9 months and tested at 4 time points-baseline; after a 3-month education-support intervention; at 6 months, after 3 months of telephone/e-mail support; and 9 months, after a 3-month period of no contact. Advanced practice registered nurses delivered the intervention. Memory enhancement methods were built into the teaching materials and delivery of the intervention. We measured the intervention's effectiveness on health status outcomes (functional status, self-efficacy, quality of life, emotional state/depressive symptoms, and metamemory) and self-care outcomes (knowledge/knowledge retention, self-care ability). Subjects evaluated the usefulness of the intervention at the end of the study.

RESULTS

The mean age of the sample was 62.4 years, with a slight majority of female participants. Participants were well educated and had other concomitant diseases, including diabetes (48%) and an unexpected degree of obesity. The intervention group showed significant improvements in functional status, self-efficacy, and quality of life (Kansas City Cardiomyopathy Questionnaire); metamemory Change and Capacity subscales (Metamemory in Adulthood Questionnaire); self-care knowledge (HF Knowledge Test); and self-care (Self-care in Heart Failure Index). Participants in both groups improved in depressive scores (Geriatric Depression Scale).

CONCLUSIONS

An in-home intervention delivered by advanced practice registered nurses was successful in several health status and self-care outcomes, including functional status, self-efficacy, quality of life, metamemory, self-care status, and HF knowledge.

Symptom perceptions and self-care behaviors in patients who self-manage heart failure

BACKGROUND

Patients with heart failure (HF) are at heightened risk for acute exacerbation requiring hospitalization. Although timely reporting of symptoms can expedite outpatient treatment and avoid the need for hospitalization, few patients recognize and respond to symptoms until acutely ill.

OBJECTIVE

The purpose of this study was to explore patients' perceptions of symptoms and self-care behaviors for symptom relief, leading up to a HF hospitalization.

METHODS

To examine prehospitalization symptom scenarios, semistructured interviews were conducted with 60 patients hospitalized for acute decompensated HF.

RESULTS

Thirty-seven patients (61.7%) said that they had a sense that "something just wasn't quite right" before their symptoms began but were unable to specify further. Signs and symptoms most often recognized by the patients were related to dyspnea (85%), fatigue (53.3%), and edema (41.7%). Few patients interpreted their symptoms as being related to worsening HF and most often attributed symptoms to changes in diet (18.3%) and medications (13.3%). Twenty-six patients (43.3%) used self-care strategies to relieve symptoms before hospital admission. More than 40% of the patients had symptoms at least 2 weeks before hospitalization.

CONCLUSIONS

Despite the wide dissemination of HF evidence-based guidelines, important components of symptom self-management remain suboptimal. Because most of HF self-management occurs in the postdischarge environment, research is needed that identifies how patients interpret symptoms of HF in the specific contexts in which patients self-manage their HF. These findings suggest the need for interventions that will help patients expeditiously recognize, accurately interpret, and use appropriate and safe self-care strategies for symptoms.

Patient participation in patients with heart failure receiving structured home care--a prospective longitudinal study

BACKGROUND

Patient participation is important for improving outcomes, respect for self-determination and legal aspects in care. However, how patients with heart failure view participation and which factors may be associated with participation is not known. The aim of this study was therefore to describe the influence of structured home care on patient participation over time in patients diagnosed with heart failure, and to explore factors associated with participation in care.

METHODS

The study had a prospective pre-post longitudinal design evaluating the influence of structured home care on participation in patients at four different home care units. Patient participation was measured using 3 scales and 1 single item. Self-care behavior, knowledge, symptoms of depression, socio- demographic and clinical characteristics were measured to explore factors associated with patient participation. Repeated measure ANOVA was used to describe change over time, and stepwise regression analyses were used to explore factors associated with patient participation.

RESULTS

One hundred patients receiving structured heart failure home care were included. Mean age was 82 years, 38 were women and 80 were in New York Heart Association functional class III. One aspect of participation, received information, showed a significant change over time and had increased at both six and twelve months. Better self-care behavior was associated with all four scales measuring different aspects of participation. Experiencing lower degree of symptoms of depression, having better knowledge, being of male sex, being of lower age, cohabiting and having home help services were associated with one or two of the four scales measuring different aspects of participation.

CONCLUSION

Patients experienced a fairly high level of satisfaction with participation in care at baseline, and there was a significant improvement over time for participation with regard to received information after being admitted to structured home care. Higher level of patient participation was consistently associated with better self-care behavior. This study shows that patient participation may need to be further focused upon, and that the association with self-care may be interesting to target in future interventions.

A comprehensive symptom diary intervention to improve outcomes in patients with HF: a pilot study

BACKGROUND

Patients with heart failure must monitor for and recognize escalating symptoms to take action to relieve symptoms and decrease hospitalizations. However, symptom monitoring is not commonly performed. One way to promote patients' engagement in symptom monitoring is by providing a symptom diary.

PURPOSE

The aim of this study was to test the effect of a comprehensive daily symptom diary intervention on event-free survival and health-related quality of life (HRQOL).

METHODS

Patients were randomized into either intervention (n = 23) or usual-care groups (n = 21). The intervention group received a symptom diary with self-care education and counseling at baseline with 5 follow-up calls for 3 months. All patients were interviewed to obtain survival data at 1 month and 3 months. HRQOL was measured at baseline, 1 month, and 3 months. Kaplan-Meier curves with the log-rank test were used to compare group differences in time to first event. Linear mixed models were conducted to examine the relationship between groups and changes in HRQOL over 3 months.

RESULTS

The intervention group had longer event-free survival than the usual-care group (P = .03). There were no differences in changes in HRQOL scores between the groups over 3 months.

CONCLUSIONS

Positive effects of the intervention on survival were found. However, there was no significant difference in changes in HRQOL.

Old and new tools to assess dyspnea in the hospitalized patient

In the assessment of dyspnea one has to take into account both the patient's own experience of the symptom and the clinicians observations of breathing rates, sounds and effort to get a complete picture. In addition, to choose appropriate treatment, the underlying cause of dyspnea needs to be assessed. While tools for clinical evaluation of heart failure have gained great interest in research and found a place in guidelines and clinical practice, the same cannot be said for instruments to assess patient self-reported dyspnea. To date, no specific dyspnea rating tool has been recommend over another. Reports from clinical practice are lacking and large; international studies in this field are warranted.

Acute decompensated heart failure: diagnosis and management

Chronic heart failure is common in the UK, with a prevalence estimated at 3% of people aged between 65 and 74 years. This prevalence increases with age and affects approximately 15% of the older population (British Heart Foundation, 2011). A significant number of such people are diagnosed after presenting to their local emergency department with severe breathlessness. Advances in patient management have improved outcomes, but the prognosis remains poor. A recent epidemiological study of patients with heart failure in north west London reported that around 14% of patients die within 6 months of diagnosis (Mehta et al, 2009). The UK national audit data of 2011-2012 reported that approximately 11% of patients admitted to hospital with acute heart failure die during their in-hospital stay. For those discharged, there is a greater-than-25% risk of death within 12 months. This risk of in-hospital and 12-month mortality varies widely, but appears to largely relate to the inpatient management and organisation of follow-up (National Institute for Cardiovascular Outcomes Research, 2012).

Multi-agent system as a new approach to effective chronic heart failure management: key considerations

Objectives

Given the importance of the follow-up of chronic heart failure (CHF) patients to reduce common causes of re-admission and deterioration of their status that lead to imposing spiritual and physical costs on patients and society, modern technology tools should be used to the best advantage. The aim of this article is to explain key points which should be considered in designing an appropriate multi-agent system to improve CHF management.

Methods

In this literature review articles were searched with keywords like multi-agent system, heart failure, chronic disease management in Science Direct, Google Scholar and PubMed databases without regard to the year of publications.

Results

Agents are an innovation in the field of artificial intelligence. Because agents are capable of solving complex and dynamic health problems, to take full advantage of e-Health, the healthcare system must take steps to make use of this technology. Key factors in CHF management through a multi-agent system approach must be considered such as organization, confidentiality in general aspects and design and architecture points in specific aspects.

Conclusions

Note that use of agent systems only with a technical view is associated with many problems. Hence, in delivering healthcare to CHF patients, considering social and human aspects is essential. It is obvious that identifying and resolving technical and non-technical challenges is vital in the successful implementation of this technology.

Heart failure patients' descriptions of participation in structured home care

BACKGROUND

To strengthen the patient's position in health care, patient participation has been decreed in policy documents and legalizations. For patients suffering from heart failure, self-care is an important part of disease management and participation is crucial to succeed with this.

OBJECTIVE

To examine how heart failure patients receiving structured home care described participation in the care.

DESIGN

Qualitative study.

SETTING AND PARTICIPANTS

Thirteen men and six women, aged between 63 and 90 years, were interviewed. The informants received structured home care at four home care units in Sweden. The interviews were analysed using qualitative content analysis.

RESULTS

Five categories with associated subcategories describing participation in care were identified: communication between patients and health-care professionals (HCPs) including time and space for dialogue and exchange of care-related information, accessibility to care through awareness of the plan for home visits or feasibility to initiate home visits, active involvement in care by engaging in self-care and collaboration with HCPs, trustful relation with HCPs, with confidence in competence and individually adapted care, options for decision making, by making decisions or entrusting decisions.

CONCLUSIONS

Patient participation could be strengthened through structured home care. Participation was facilitated when there was a balance between the patient's own preferences to influence care and the health-care professional's actions and values and the organization of care. Barriers to participation could depend on the health-care organization, lack of continuity and confidence in HCPs.

Uncertainty in illness among patients with chronic heart failure is less in person-centred care than in usual care

BACKGROUND

Many patients with chronic heart failure (CHF) experience uncertainty regarding the treatment and characteristics of their illness. Person-centred care (PCC) emphasizes patient involvement in care. We have previously shown that PCC improved outcomes such as length of hospital stay and activities of daily living in patients with CHF. The impact of PCC on self-reported uncertainty in illness among patients hospitalized for CHF is still unknown.

AIM

To evaluate whether PCC is associated with less self-reported uncertainty in illness compared with usual care in patients hospitalized for worsening CHF.

METHODS

Using a controlled before-and-after design, eligible CHF patients were assigned to either a usual care group or a PCC intervention group. Patient-reported uncertainty in illness was assessed at hospital discharge with the Cardiovascular Population Scale (CPS). The CPS consists of two domains: 1) Ambiguity (about illness severity); and 2) Complexity (of treatment and system of care).

RESULTS

Two hundred and forty-eight patients were included in the study; 123 in the usual care group and 125 in the PCC intervention. The PCC group had better scores than the usual care group in the CPS domains complexity (M=15.2, SD=4.7 vs. M=16.8, SD=4.7; p=0.020) and ambiguity (M=27.8, SD=6.6 vs. M=29.8, SD=6.9; p=0.041).

CONCLUSION

Patients with CHF were less uncertain in their illness after PCC, which may help to equip and empower patients to manage their illness. Together with earlier findings of shortened hospital stay and improved activities of daily living, this indicates that PCC should be a standard approach for hospital care of patients with worsening CHF.

A middle-range theory of self-care of chronic illness

Nearly 50% of adults have one or more chronic illnesses. Self-care is considered essential in the management of chronic illness, but the elements of self-care in this context have not been specified in a middle-range theory. This article describes a middle-range theory of self-care that addresses the process of maintaining health with health promoting practices within the context of the management required of a chronic illness. The key concepts include self-care maintenance, self-care monitoring, and self-care management. Assumptions and propositions of the theory are specified. Factors influencing self-care including experience, skill, motivation, culture, confidence, habits, function, cognition, support from others, and access to care are described.

Understanding help-seeking decisions in people with heart failure: a qualitative systematic review

OBJECTIVE

To understand the process of help-seeking among heart failure patients from the perspectives of patients, caregivers and health professionals.

DESIGN

Systematic review using qualitative meta-synthesis.

METHODS

A systematic search (20th May 2011) was conducted to identify studies published in English as full papers ≥1995 reporting primary qualitative data with extractable heart failure-specific data or themes related to help-seeking in patients, caregivers or health professionals. Databases searched were: CINAHL, Medline, PsycInfo, Social Science Citation Index, Embase, Social policy/Practice, SocIndex, Ageline, Health Source Nursing, Scopus; additionally, we consulted with experts and manually searched references.

RESULTS

58 studies (990 patients; 274 female, 527 male, 189 sex not described; 229 caregivers, 79 health professionals) were included. Heart failure help-seeking was embedded in daily experiences of heart failure but ongoing symptoms were confusing, ambiguous and disruptive; little support was available from professionals to interpret the presence and significance of fluctuations in symptoms for help-seeking. Other significant barriers to help-seeking were: avoidance-based coping, fear of hospitals and misplaced reluctance to be burdensome. Help-seeking was facilitated by good involvement and frank communication between patients, caregivers and health professionals and the presence of a sense of elevated personal risk.

CONCLUSION

Health services should harness primary care providers and support patients and caregivers to prioritize development of objective symptom monitoring skills, recognize and personally assimilate the elevated risks of heart failure and help-seeking delays and discourage avoidance-based coping and unwarranted concerns that downplay the significance of heart failure and urgency to address symptoms.

Patients with worsening chronic heart failure who present to a hospital emergency department require hospital care

Background

Chronic heart failure (CHF) is a major public health problem characterised by progressive deterioration with disabling symptoms and frequent hospital admissions. To influence hospitalisation rates it is crucial to identify precipitating factors.

To characterise patients with CHF who seek an emergency department (ED) because of worsening symptoms and signs and to explore the reasons why they are admitted to hospital.

Method

Patients (n = 2,648) seeking care for dyspnoea were identified at the ED, Sahlgrenska University Hospital/Östra. Out of 2,648 patients, 1,127 had a previous diagnosis of CHF, and of these, 786 were included in the present study with at least one sign and one symptom of worsening CHF.

Results

Although several of the patients wanted to go home after acute treatment in the ED, only 2% could be sent home. These patients were enrolled in an interventional study, which evaluated the acute care at home compared to the conventional, in hospital care. The remaining patients were admitted to hospital because of serious condition, including pneumonia/respiratory disease, myocardial infarction, pulmonary oedema, anaemia, the need to monitor cardiac rhythm, pathological blood chemistry and difficulties to communicate.

Conclusion

The vast majority of patients with worsening CHF seeking the ED required hospital care, predominantly because of co-morbidities. Patients with CHF with symptomatic deterioration may be admitted to hospital without additional emergency room investigations.

Association between prehospital delay and subsequent clinical course in patients with/hospitalized for heart failure

BACKGROUND

The clinical consequences of prehospital delay in heart failure (HF) patients are unknown. This study explores the relationship between prehospital delay of HF patients and length of hospital stay, plasma values of brain natriuretic peptides (BNP) as well as the association of delay with all-cause mortality, readmission for HF, or all-cause readmissions during short- (60 days) and long-term (18 months) follow-up.

METHODS

Data from 1023 hospitalized HF patients mean aged 71 years from the Coordinating study evaluating Outcomes of Advising and Counselling in HF study were analyzed.

RESULTS

Patients who delayed less than 1 day had significantly shorter stay in hospital (10 days vs. 11 days, P = 0.033). They also had significantly (P = 0.004) lower median plasma values of BNP (377 pg/mL) at discharge compared to patients who delayed >24 hours (492 pg/mL). Delay was not related to all-cause mortality and/or readmissions for HF.

CONCLUSION

Although patients with a prehospital delay less than 1 day were more symptomatic on admission, they had a shorter hospital stay as well as lower plasma values of BNP at discharge. Delay was not associated hospital readmissions or mortality after discharge.

Effect of a telemonitoring-facilitated collaboration between general practitioner and heart failure clinic on mortality and rehospitalization rates in severe heart failure: the TEMA-HF 1 (TElemonitoring in the MAnagement of Heart Failure) study

AIMS

Chronic heart failure (CHF) patients are frequently rehospitalized within 6 months after an episode of fluid retention. Rehospitalizations are preventable, but this requires an extensive organization of the healthcare system. In this study, we tested whether intensive follow-up of patients through a telemonitoring-facilitated collaboration between general practitioners (GPs) and a heart failure clinic could reduce mortality and rehospitalization rate.

METHODS AND RESULTS

One hunderd and sixty CHF patients [mean age 76 ± 10 years, 104 males, mean left ventricular ejection fraction (LVEF) 35 ± 15%] were block randomized by sealed envelopes and assigned to 6 months of intense follow-up facilitated by telemonitoring (TM) or usual care (UC). The TM group measured body weight, blood pressure, and heart rate on a daily basis with electronic devices that transferred the data automatically to an online database. Email alerts were sent to the GP and heart failure clinic to intervene when pre-defined limits were exceeded. All-cause mortality was significantly lower in the TM group as compared with the UC group (5% vs. 17.5%, P = 0.01). The total number of follow-up days lost to hospitalization, dialysis, or death was significantly lower in the TM group as compared with the UC group (13 vs. 30 days, P = 0.02). The number of hospitalizations for heart failure per patient showed a trend (0.24 vs. 0.42 hospitalizations/patient, P = 0.06) in favour of TM.

CONCLUSION

Telemonitoring-facilitated collaboration between GPs and a heart failure clinic reduces mortality and number of days lost to hospitalization, death, or dialysis in CHF patients. These findings need confirmation in a large trial.

Non-symptom-related factors contributing to delay in seeking medical care by patients with heart failure: a narrative review

BACKGROUND

Delay in seeking timely medical care by patients with acute coronary syndrome and stroke has been well established in the literature, but less is known about delay in care-seeking behavior by patients with heart failure (HF). The purpose of this narrative review was to synthesize the literature regarding non-symptom-related factors that contribute to delay in seeking medical care for HF symptoms.

METHODS AND RESULTS

A literature search of Scopus, Medline, and Pubmed was conducted for published articles from database inception to July 2009. Available evidence has shown that non-symptom-related factors, such as HF severity, HF history, age, and ethnocultural background, were related to delay in certain studies; however, null results have also been reported. Other non-symptom-related factors, such as male gender, initial contact with a primary care physician, arriving in the emergency department by means other than ambulance, and patient responses such as self-care, low anxiety, and hopelessness, may play a role in longer delay.

CONCLUSIONS

Although this review identified several non-symptom-related factors that may be implicated in care-seeking delay, health care professionals should be vigilant in identifying all high-risk individuals and educating them about warning signs of HF. Moreover, access to outpatient chronic disease management programs that may have potential to reduce care-seeking delay behavior should be explored.

A remote patient monitoring system for congestive heart failure

Congestive heart failure (CHF) is a leading cause of death in the United States affecting approximately 670,000 individuals. Due to the prevalence of CHF related issues, it is prudent to seek out methodologies that would facilitate the prevention, monitoring, and treatment of heart disease on a daily basis. This paper describes WANDA (Weight and Activity with Blood Pressure Monitoring System); a study that leverages sensor technologies and wireless communications to monitor the health related measurements of patients with CHF. The WANDA system is a three-tier architecture consisting of sensors, web servers, and back-end databases. The system was developed in conjunction with the UCLA School of Nursing and the UCLA Wireless Health Institute to enable early detection of key clinical symptoms indicative of CHF-related decompensation. This study shows that CHF patients monitored by WANDA are less likely to have readings fall outside a healthy range. In addition, WANDA provides a useful feedback system for regulating readings of CHF patients.

Symptom clusters predict event-free survival in patients with heart failure

BACKGROUND

Physical symptoms are likely to occur in clusters that may be associated with adverse outcome in patients with heart failure (HF). Despite the importance of early recognition of worsening symptoms in HF management, the impact of physical symptoms on adverse outcome has not been explored in the context of symptom clusters.

PURPOSE

The purposes of this study were to explore which physical symptom clusters occur in HF patients and to determine the impact of symptom clusters on event-free survival.

METHODS

A total of 421 patients (60% male; 62 [SD, 14] years; 72% New York Heart Association class II/III) completed the modified Memorial Symptom Assessment Scale-Heart Failure to measure physical symptoms during an index hospitalization in Seoul, Korea. Times to first event of cardiac rehospitalization and cardiac death were collected for 12 months after discharge and confirmed by review of hospital records. An agglomerative hierarchical clustering approach with Ward's method was used to identify symptom clusters. Hierarchical Cox hazard regression was used to determine the impact of symptom clusters on cardiac rehospitalization and cardiac mortality.

RESULTS

Two distinct symptom clusters, the dyspneic and the weary symptom clusters, occurred in patients with HF. Shortness of breath, difficulty breathing when lying flat, and waking up breathless at night comprised the dyspneic symptom cluster. Lack of energy, lack of appetite, and difficulty sleeping comprised the weary symptom cluster. In hierarchical Cox hazard regression, elevated distress from the weary symptom cluster independently predicted cardiac rehospitalization (hazard ratio, 1.45; 95% confidence interval, 1.09-1.93), and increased distress from the dyspneic symptom cluster independently predicted cardiac mortality (hazard ratio, 2.00; 95% confidence interval, 1.16-3.34).

CONCLUSION

The weary and the dyspneic symptom clusters predicted cardiac rehospitalization and cardiac mortality, respectively. Patient education for self-monitoring of symptoms should focus on symptom clusters rather than single symptom.

Signs and symptoms of heart failure: are you asking the right questions?

BACKGROUND

Patients may not verbalize common and atypical signs and symptoms of heart failure and may not understand their association with worsening disease and treatments.

OBJECTIVES

To examine prevalence of signs and symptoms relative to demographics, care setting, and functional class.

METHODS

A convenience sample of 276 patients (164 ambulatory, 112 hospitalized) with systolic heart failure completed a 1-page checklist of signs and symptoms experienced in the preceding 7 days (ambulatory) or in the 7 days before hospitalization. Demographic and medical history data were collected.

RESULTS

Mean age was 61.6 (SD, 14.8) years, 65% were male, 58% were white, and 45% had ischemic cardiomyopathy. Hospitalized patients reported more sudden weight gain, weight loss, severe cough, low/orthostatic blood pressure, profound fatigue, decreased exercise, restlessness/confusion, irregular pulse, and palpitations (all P < .05). Patients in functional class IV reported more atypical signs and symptoms of heart failure (severe cough, nausea/vomiting, diarrhea or loss of appetite, and restlessness, confusion, or fainting, all P <or= .001). Sudden weight gain increased from 5% in functional class I to 37.5% in functional class IV (P < .001). Dyspnea occurred in all functional classes (98%-100%) and both settings (92%-100%). Profound fatigue was associated with worsening functional class (P < .001) and hospital setting (P = .001); paroxysmal nocturnal dyspnea was associated with functional class IV (P = .02) and hospital setting (P < .001).

CONCLUSION

Profound fatigue is more reliable than dyspnea as an indicator of functional class. Nurses must recognize atypical signs and symptoms of worsening functional class to determine clinical status and facilitate patient care decisions.

Length of delay in seeking medical care by patients with heart failure symptoms and the role of symptom-related factors: a narrative review

AIMS

The delay in seeking timely medical care by patients with acute coronary syndrome and stroke is well established. Less is known about the delay in patients with heart failure (HF). Reducing the delay in seeking care and the early initiation of treatment is associated with improved outcomes in patients with HF. The purpose of this narrative review was to describe the length of the delay in seeking care for HF symptoms and identify symptom-related factors that contribute to the delay in seeking medical care.

METHODS AND RESULTS

A literature search was conducted to identify English language studies that (i) describe the length of care-seeking delay for HF symptoms and/or (ii) identify symptom-related factors that contribute to delay in seeking medical care. The results of this review demonstrate that upon hospital admission patients report wide variations in median symptom time course from 2 h to 7 days from the onset of symptoms to hospital admission. The ability of patients to recognize, interpret, and appraise HF symptoms has been demonstrated to be limited. Symptom characteristics such as dyspnoea, oedema, orthopnoea, higher somatic awareness, higher symptom distress, nocturnal symptom onset, and the pattern of symptom onset were related to longer delay in care-seeking for HF symptoms. Furthermore, cognitive responses to HF may also play an important role in symptom appraisal.

CONCLUSION

Delays in seeking care for HF symptoms have been shown to range from hours to days from symptom onset to hospital admission. Healthcare professionals should therefore be more vigilant in identifying high-risk individuals and educating them about the warning signs of HF. Moreover, access to outpatient chronic disease management programmes may have the potential to reduce these delays.

Symptom variability, not severity, predicts rehospitalization and mortality in patients with heart failure

BACKGROUND

Inability of heart failure (HF) patients to recognize worsening symptoms that herald an exacerbation is a common reason for HF readmissions.

AIMS

To examine the relationship between patterns of HF symptom variability, and HF event-free survival.

METHODS

Patients with HF (N=71) rated HF symptoms daily for 30 days. Symptoms were rated on a 10 point scale anchored at the extreme ends by "worst symptom could be" and "best symptom could be". Patients were followed for an average of 1 year to track HF and cardiac rehospitalizations and all-cause mortality.

RESULTS

Cox regression comparing event-free survival between patients who had highly variable symptom ratings across the 30-days and those whose symptoms were less variable revealed worse event-free survival in patients with more variable symptoms of shortness of breath or edema. Symptom variability predicted event-free survival independently of severity of symptoms, ejection fraction, comorbidities, age and gender. Symptom severity did not predict rehospitalization or mortality.

CONCLUSION

Regardless of symptom severity, patients whose symptoms fluctuated in an improving and worsening pattern were at substantially greater risk for poorer event-free survival. These patients may become accustomed to this pattern such that they expect symptoms to improve and thus do not seek treatment with worsening symptoms.

Does cognitive impairment predict poor self-care in patients with heart failure?

AIMS

Cognitive impairment occurs often in patients with chronic heart failure (CHF) and may contribute to sub-optimal self-care. This study aimed to test the impact of cognitive impairment on self-care.

METHODS AND RESULTS

In 93 consecutive patients hospitalized with CHF, self-care (Self-Care of Heart Failure Index) was assessed. Multiple regression analysis was used to test a model of variables hypothesized to predict self-care maintenance, management, and confidence. Variables in the model were mild cognitive impairment (MCI; Mini-Mental State Exam and Montreal Cognitive Assessment), depressive symptoms (Cardiac Depression Scale), age, gender, social isolation, education level, new diagnosis, and co-morbid illnesses. Sixty-eight patients (75%) were coded as having MCI and had significantly lower self-care management (eta(2)= 0.07, P < 0.01) and self-confidence scores (eta(2)= 0.05, P < 0.05). In multivariate analysis, MCI, co-morbidity index, and NYHA class III or IV explained 20% of the variance in self-care management (P < 0.01); MCI made the largest contribution explaining 9% of the variance. Increasing age and symptoms of depression explained 13% of the variance in self-care confidence scores (P < 0.01).

CONCLUSION

Cognitive impairment, a hidden co-morbidity, may impede patients' ability to make appropriate self-care decisions. Screening for MCI may alert health professionals to those at greater risk of failed self-care.

Why do elders delay responding to heart failure symptoms?

BACKGROUND

Elders with heart failure (HF) are at risk for frequent hospitalizations for symptom management. Repeated admissions are partly related to delay in responding to HF symptoms. Contextual factors such as prior illness experiences and social/emotional factors may affect symptom interpretation and response. The Self-Regulation Model of Illness guided this study as it acknowledges the dynamic nature of illness and influence of contextual factors and social environment on the interpretation and response to symptoms.

OBJECTIVE

The purpose of this study was to describe contextual factors related to symptom recognition and response among elders hospitalized with decompensated HF.

METHODS

A mixed-methods design was used. The HF Symptom Perception Scale (physical factors), Specific Activity Scale (functional performance), and Response to Symptoms Questionnaire (cognitive/emotional factors) were administered to participants aged >or=65 years. Symptom duration and clinical details were collected by interview and chart review. Open-ended questions addressing the symptom experience, including the context in which symptoms occurred, were audiotaped, transcribed, analyzed, and compared across cases to inform the quantitative data.

RESULTS

The convenience sample (n = 77) was 48% female, 85.7% were non-Hispanic White, and mean age was 75.9 years (SD = 7.7 years). Functional performance was low (81% class III/IV). The most frequently reported symptoms were dyspnea, dyspnea on exertion, and fatigue. Median duration of early symptoms of HF decompensation was 5 to 7 days, but dyspnea duration ranged from 30 minutes to 90 days before action was taken. Longer dyspnea duration was associated with higher physical symptom distress (r = .30) and lower anxiety (r = -.31). Sensing and attributing meaning to early symptoms of HF decompensation were problematic.

DISCUSSION

The physical symptom experience and the cognitive and emotional response to HF symptoms were inadequate for timely care seeking for most of this older aged sample.

Patient and informal caregivers' knowledge of heart failure: necessary but insufficient for effective self-care

AIMS

Self-care of heart failure (HF) is a process that is important, complex, and challenging. Little is understood of the contextual factors influencing self-care. We aimed to examine the individual and contextual factors perceived by patients and their informal caregivers' to influence their willingness and capacity to undertake effective HF self-care.

METHODS AND RESULTS

This was a qualitative study using semi-structured interviews with 42 patients with HF (NYHA Class II and III, mean age: 76 years, 64% males) and 30 nominated caregivers (63% spouses). All patients experienced severe and intrusive HF symptoms; a large proportion of patients practiced some of the range of recommended self-care activities. However, links between knowledge of HF and self-care were weak and long delays in seeking professional care were frequent. Factors consistently reported to influence self-care were faith in health professionals, beliefs about the local health system, and values linked to work associated with place, history, and culture.

CONCLUSION

Knowledge of HF and its management is a necessary though not sufficient determinant of HF self-care. Individual and contextual factors influence willingness and capacity to undertake effective HF self-care.

Reasons for readmission in heart failure: Perspectives of patients, caregivers, cardiologists, and heart failure nurses

OBJECTIVE

Despite efforts to improve outcomes in heart failure (HF), readmission rates remain relatively high. Reasons for readmission from different perspectives (patient, caregiver, health care providers) may help to optimize the future management of patients with HF. The aims of this study are to 1) gain insight into reasons for HF readmission from the perspective of patients, caregivers, cardiologists, and HF nurses; 2) examine similarities and differences in perspectives on the reason for an HF readmission, and 3) describe possibilities to prevent an HF readmission from different perspectives.

METHODS AND RESULTS

Data on reasons for readmission were collected on 173 readmissions. Perspectives of patients, caregivers, cardiologists, and HF nurses were collected by interview and questionnaire. Worsening HF as the sole reason for readmission was reported most often; however, 36% of caregivers, 56% of patients, and 63% to 65% of health care providers indicated that other factors, such as comorbidity, nonadherence, and nonoptimal medication, were important contributing factors. In only 34% of readmissions, patients and their caregivers agreed with health care providers on the underlying reason. Respondents reported that 23% to 31% of the readmissions could probably have been prevented if adherence were higher, patients requested help earlier, and adequate multidisciplinary professional help were available.

CONCLUSION

To prevent future readmissions of patients with HF, it is important to fully understand the reasons for readmission by gaining insight on the reason for readmission from different perspectives. Also, we may need another approach to prevent adverse outcomes in which other medical problems and new strategies to improve adherence have to be considered.
