Symptoms experience: a concept analysis

Two Methods for Calculating Symptom Cluster Scores

BACKGROUND

Symptom clusters are conventionally distilled into a single score using composite scoring, which is based on the mathematical assumption that all symptoms are equivalently related to outcomes of interest; this may lead to a loss of important variation in the data.

OBJECTIVES

This article compares two ways of calculating a single score for a symptom cluster: a conventional, hypothesis-driven composite score versus a data-driven, reduced rank regression score that weights the symptoms based on their individual relationships with key outcomes.

METHODS

We conducted a secondary analysis of psychoneurological symptoms from a sample of 356 low-income mothers. Four of the psychoneurological symptoms (fatigue, cognitive dysfunction, sleep disturbance, and depressed mood) were measured with the Center for Epidemiological Studies Depression Scale; the fifth (pain) was measured using an item from the Medical Outcomes Study 12-item Short Form Health Survey (SF-12). Mothers' function was measured using the 12-item Short Form Health Survey. The composite score was calculated by summing standardized scores for each individual psychoneurological symptom. In contrast, reduced rank regression weighted the individual symptoms using their respective associations with mothers' function; the weighted individual symptom scores were summed into the reduced rank regression symptom score.

RESULTS

The composite score and reduced rank regression score were highly correlated at .93. The cluster of psychoneurological symptoms accounted for 53.7% of the variation in the mothers' function. Depressed mood and pain accounted for almost all the explained variation in mothers' function at 37.2% and 15.0%, respectively.

DISCUSSION

The composite score approach was simpler to calculate, and the high correlation with the reduced rank regression score indicates that the composite score reflected most of the variation explained by the reduced rank regression approach in this data set. However, the reduced rank regression analysis provided additional information by identifying pain and depressed mood as having the strongest association with a mother's function, which has implications for understanding which symptoms to target in future interventions. Future studies should also explore composite versus reduced rank regression approaches given that reduced rank regression may yield different insights in other data sets.

Symptom Map of Endocrine Therapy for Breast Cancer: A Scoping Review

BACKGROUND

Multiple symptoms associated with endocrine therapy have a detrimental impact on medication adherence and quality of life.

OBJECTIVE

The purpose of this scoping review is to map the symptoms during endocrine therapy for breast cancer to provide implications for current practice and suggestions for future research.

METHODS

The PubMed, CINAHL, and China Science Periodical Databases were searched to identify related studies published in English and Chinese languages. References of included articles were reviewed for additional eligible studies. Of the 2551 articles identified, 57 articles met inclusion criteria and were included in this scoping review.

RESULTS

Evidence for the 16 most studied symptoms and 15 most prevalent symptoms were synthesized. Five key symptoms associated with endocrine therapy were identified, including joint/muscle pain, hot flashes, low sexual interest/desire, joint/muscle stiffness, and fatigue/lack of energy. Rarely studied but highly prevalent symptoms and other gaps in the symptom science during endocrine therapy for breast cancer were identified.

CONCLUSION

Nurses caring for women receiving endocrine therapy for breast cancer should assess the 5 key symptoms identified. There remain substantial gaps in the science related to the symptom experience during endocrine therapy for breast cancer. Future studies should focus on the domains of symptom intensity and distress, specific understudied symptoms, symptom clusters, and development of symptom assessment instruments specific to symptoms associated with endocrine therapy.

IMPLICATIONS FOR PRACTICE

This scoping review identified 5 well-studied and highly prevalent symptoms that should be assessed in women with breast cancer receiving endocrine therapy.

Exploration of symptom experience in kidney transplant recipients based on symptoms experience model

PURPOSE

Kidney transplant recipients suffer from a variety of symptoms, and symptom management is crucial in improving their quality of life (QOL). Accordingly, this study aims to identify the symptoms experienced by kidney transplant recipients and examine the relationship amongst antecedents, symptom experience and QOL of recipients in China.

METHODS

A total of 300 kidney transplant recipients were investigated in one of the most first-rate hospitals in China by asking them to fill out a self-designed general questionnaire, the Symptom Experience Scale, the Sense of Coherence Scale (Chinese version), the Revised Life Orientation Test (Chinese version) and the 36-item Short Form Health Survey (Chinese version).

RESULTS

Kidney transplant recipients experienced multiple symptoms that were frequent, severe and bothersome. The final model showed significant consistency with the data. In the QOL model, post-transplant time, complications, immunosuppressive agents and sense of coherence explained 30.7% of the variance of symptom experience. Moreover, habitual residence, economic burden, post-transplant time, kidney function, optimism and symptom experience accounted for 70.6% of the variance on QOL.

CONCLUSIONS

We can explain the relationship between antecedents, symptom experience and QOL amongst Chinese kidney transplant recipients by using Symptoms Experience Model. Clinicians and caregivers can manage the recipient's symptoms during follow-up from psychological, physical and medication management perspectives. Improving sense of coherence, maintaining optimism and managing symptoms are essential for enhancing QOL.

Help-seeking behaviour for cancer symptoms: an evolutionary concept analysis

BACKGROUND

Cancer survival largely depends on its early diagnosis. Therefore, assessing help-seeking behaviours among people with potential symptoms of cancer is essential.

AIM

This study aimed to analyse the concept of help-seeking behaviour for cancer symptoms.

METHODS

This concept analysis was conducted using Rodger's evolutionary method. An online literature search was conducted in the PubMed, Scopus and Cochrane databases to find relevant articles published from 2000 to 2017 in English peer-reviewed journals. In total, ninety articles were included in the study. Through thematic analysis, the data were analysed for the definitions, attributes, antecedents and consequences of the concept of help-seeking behaviour for cancer symptoms.

RESULTS

The concept of help-seeking behaviour for cancer symptoms includes a chain of behaviours and is defined as the process of informed decision-making for seeking medical help and using healthcare services after the detection of the first potential cancer symptoms. The attributes of the concept of help-seeking behaviour for cancer symptoms include process, problem-centeredness, intentional action and interpersonal interaction. Antecedents of the concept of help-seeking behaviour for cancer symptoms were broadly categorised as its facilitators and barriers, among which old age, young age, marriage, low education level, positive family history of cancer, fear over cancer, low perceived threat, symptom disclosure to significant others are both facilitator and barrier. The consequences of the concept of help-seeking behaviour for cancer symptoms were also broadly categorised in the two main categories of positive consequences and adverse consequences.

CONCLUSIONS

Help-seeking behaviour is a multidimensional time-dependent and context-bound concept which is usually defined based on the concept of time in order to facilitate its measurement. It is generally used for assessing patients' delay in seeking medical help. The findings of this study provide better understanding about the concept of help-seeking behaviour for cancer symptoms and its implications for research and practice.

Predictors for Early Physical Recovery for General and Orthopedic Patients after Major Surgery: Structural Equational Model Analyses

BACKGROUND

Attention to factors that may affect patients' ability to experience enhanced recovery after surgery is essential in planning for postoperative care.

AIMS

To create models of predefined pre,- peri-, and postoperative variables in order to analyze their impact on patients' physical recovery on postoperative days 1 and 2 after major orthopedic and general surgery.

DESIGN

An exploratory design with repeated measures was used, including 479 patients who had undergone orthopedic (289) or general surgery (190) at three hospitals.

METHODS

Pain, nausea, and level of physical ability were measured preoperatively and on postoperative days 1 and 2 by using the Numerical Rating Scale and items from the Postoperative Recovery Profile. Structural equation modeling was used to explore the impact of the predefined variables on patients' physical recovery.

RESULTS

The orthopedic group contained significantly more women and significantly more patients with pain and opioid use. Although the models showed good fit, "traditional" preoperative (pain, nausea, physical abilities, chronic pain, opioid use) and perioperative variables (anesthesia, length of surgery) constituted few (orthopedic) or no (general surgery) predictive properties for physical recovery. Postoperative average pain intensity, average nausea intensity, and physical ability explained physical recovery on day 1, and physical recovery on day 1 predicted physical recovery on day 2.

CONCLUSIONS

"Traditional" predictors had little effect on patients' postoperative physical recovery, while associations with common postoperative symptoms were shown. Further research is needed to explore additional variables affecting early physical recovery and to understand how soon patients are physically ready to return home.

Does palliative chemotherapy really palliate and are we measuring it correctly? A mixed methods longitudinal study of health related quality of life in advanced soft tissue sarcoma

Objective

Soft tissue sarcoma (STS) is a rare cancer type that when locally advanced or metastatic, is predominantly treated with palliative chemotherapy with the aim of improving both quantity and quality of life. Given modest survival data after commencing first line chemotherapy, this study examines (i) what constitutes health related quality of life (HRQoL), (ii) whether the most commonly used HRQoL assessment tool measures this and (iii) to what extent HRQoL, and its components, change during and after treatment.

Design

Mixed-methods longitudinal study of 66 sarcoma patients living with STS (42 commencing chemotherapy, 24 under surveillance after completing chemotherapy) involving serial EORTC QLQ-C30 questionnaires and nested-qualitative semi-structured interviews with a sub-sample of participants. EORTC QLQ-C30 score change from baseline to primary evaluation point was examined using a paired t-test. Interviews were analysed using the framework approach before both datasets were integrated.

Results

Five main factors, including control of pain, were identified by study participants as important components of HRQoL; these are examined within the EORTC QLQ-C30. However, others e.g. independence loss and common causes of anxiety, are not. Whilst social and psychological domains are addressed by the EORTC QLQ-C30, the quantitative change over time did reflect qualitative descriptions of decline.

The mean overall EORTC QLQ-C30 HRQoL score deteriorated from baseline (60.4) to the primary evaluation point (50.2) [change of -10.2, t-test: -2.70, p = 0.01] for those receiving chemotherapy; this was in concordance with patients’ qualitative accounts. Baseline overall HRQoL scores were higher in the surveillance group suggesting a correlation with chemotherapy response and longer-term improvement in HRQoL. The evidence from both HRQoL scores and qualitative accounts indicated that the presence and control of physical symptoms were particularly important in maintaining HRQoL. Whilst fatigue deteriorated on chemotherapy (baseline 41.7 to 52.8; change of +11.1, t-test +2.51, p<0.05), pain (baseline 41.5 to 32.1; change -9.4, t-test -2.06 p<0.05) and sleep disturbance (43.1 to 28.5; change -14.6, t-test –3.05, p<0.05) both improved.

Conclusion

A key finding was that the EORTC QLQ-C30 assesses some but not all of the patient-reported components of HRQoL in sarcoma patients highlighting the need for either STS specific modules within the EORTC QLQ-C30 or a completely new STS specific HRQoL tool. First line palliative chemotherapy improves specific symptoms known to be prevalent and to influence HRQoL in this patient group which in some patients may translate to sustained improvement in HRQoL: further exploration and validation of these findings in larger prospective studies are warranted.

Subjective cognitive functioning and associations with psychological distress in adult brain tumour survivors

PURPOSE

The impact of brain tumour on subjective cognitive function (SCF) has received little attention despite the implications of these perceptions for quality of life. SCF consists of two related yet distinct components, perceived cognitive impairment (PCI) and perceived cognitive abilities (PCA). This study compared the SCF of adult brain tumour survivors and healthy controls and examined demographic, illness-related, and psychological factors associated with SCF.

METHOD

Sixty-five adult survivors with primary brain tumour (age, 22-75 years), and 65 age- and sex-matched controls were recruited. Participants with brain tumour completed the Brief Test of Adult Cognition by Telephone, Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog), ratings of physical symptoms, Depression Scale of the Depression Anxiety Stress Scales-21 (DASS-Depression), and Generalized Anxiety Disorder-7 (GAD-7) scale. Controls completed the FACT-Cog, DASS-Depression, and GAD-7.

RESULTS

Adult brain tumour survivors reported significantly greater PCI and lower PCA than controls, after accounting for anxiety. Higher PCI was significantly related to fatigue, pain, treatment-related side-effects, anxiety, and depression. Lower PCA was significantly associated with fatigue, pain, poorer objective cognitive function, lower education, anxiety, and depression. Anxiety uniquely accounted for 9-14% of variance in SCF.

CONCLUSIONS

Adult brain tumour survivors were found to experience poorer SCF than healthy controls after accounting for anxiety. SCF was related to multiple factors after brain tumour; however, an independent association with anxiety was identified.

IMPLICATIONS FOR CANCER SURVIVORS

These findings highlight the potential value of psychological interventions targeting anxiety and cognitive effects to improve quality of survivorship after brain tumour.

Symptom Assessment in Patients with Advanced Cancer: Are the Most Severe Symptoms the Most Bothersome?

Objective: We investigated correspondence between symptom severity and symptom bothersomeness in patients with advanced cancer. Background: Symptom severity is commonly assessed in clinical cancer settings, but bothersomeness of these symptoms is less often measured. Methods: Participants with advanced cancer enrolled in a cluster-randomized trial of early palliative care completed the Edmonton Symptom Assessment System (ESAS) and the quality of life at the end of life (QUAL-E) measure as part of their baseline assessment. For each symptom, we examined the correspondence between the symptom being indicated as most severe on the ESAS and rated as most bothersome on the QUAL-E. Results: For the 386 patients who completed relevant sections of the ESAS and QUAL-E, tiredness (32.8%), sleep (23.8%), and appetite (20.2%) were most frequently rated as most severe, whereas pain (28.9%) and tiredness (24.3%) were most frequently indicated as most bothersome. The most bothersome and most severe symptom corresponded in 42%. Pain and/or tiredness were consistently among the top three most bothersome symptoms, whereas appetite was frequently rated the most severe symptom but was rarely perceived as the most bothersome. The probability that patients rating a symptom as most severe would also rate it as most bothersome was highest for pain (66%), nausea (58%), and tiredness (40%). Discussion: ESAS symptom severity does not necessarily indicate patients' most bothersome symptom; regardless of severity, pain and tiredness are most frequently perceived as most bothersome. Further research should investigate the clinical benefits of patients also indicating their three most bothersome ESAS symptoms.

Understanding and Measuring Symptom Burden in Heart Failure: A Concept Analysis

Heart failure is a common, complex, and costly condition accompanied by a high degree of symptom burden. The concept of heart failure symptom burden has been used and measured inconsistently in research. To develop effective symptom management and palliation strategies, a clear conceptual understanding is needed. Rodgers' evolutionary method of concept analysis was used to identify articles in CINAHL, Embase, Scopus, and PubMed focused on chronic heart failure. Analysis of 20 articles revealed key attributes (subjectivity, negative impact on daily life and/or overall functioning, synergistic symptom associations, and symptom exacerbation), related terms (symptom distress and symptom experience), a surrogate term (heart failure burden), antecedents (heart failure classification or stage), and consequences (increased morbidity/mortality, decreased functioning, increased symptom prevalence/severity, decreased quality of life, and recurrent hospital admissions). No gold standard for measurement was identified. Research is needed to validate heart failure symptom burden measurement strategies across populations.

The Effect of Symptom Clusters on Quality of Life Among Patients With Type 2 Diabetes

Purpose

The purpose of this study was to examine the collective effect of a symptom cluster (depression, anxiety, fatigue, and impaired sleep quality) at baseline on the quality of life (QOL) of patients with type 2 diabetes (T2DM) over time.

Methods

This was a secondary data analysis of 302 patients with T2DM who presented with both hypertension and hyperlipidemia. All of the participants were enrolled in a randomized controlled intervention study testing strategies to improve medication adherence. The psychological symptoms and QOL were assessed at baseline, 6 months, and 12 months. Cluster analysis was used to identify subgroups of patients based on the severity of symptoms at baseline.

Results

Hierarchical cluster analysis identified 4 patient subgroups: all low severity, mild, moderate, and all high severity. There were significant differences in patients’ QOL overall among the 4 subgroups. Compared with the all-low-severity subgroup, subgroups with higher severity of the 4 symptoms had poorer QOL across all 3 time points. QOL was most impacted by trait anxiety across the 3 time points.

Conclusion

QOL was significantly impacted by psychological symptom clusters among patients with T2DM. Healthcare providers should not neglect psychological symptoms that patients experience. It is important to assess and manage these symptoms to improve QOL among patients with diabetes.

Introducing a model for emotional distress in respiratory disease: A systematic review and synthesis of symptom management models

AIM

To undertake a theoretical systematic review to develop a conceptual model of illness-related emotional distress in the context of symptom management in chronic respiratory disease.

DESIGN

We performed a systematic search to identify conceptual models.

DATA SOURCES

Electronic databases MEDLINE, CINAHL, EMBASE and PsycINFO were searched and papers included from inception of the search term until June 2017.

REVIEW METHODS

The review was conducted following Pound and Campbell's and Turner's theory synthesis. Conceptual models were appraised using Kaplan's criteria. Models were excluded if they referred to a specific condition and/or lacked clarity.

RESULTS

This synthesis, which includes five models and additional evidence, yielded a new conceptual model describing the processes of regulation and symptom self-management in chronic respiratory disease. Identified sources of illness-related emotional distress are new or increased symptoms, additional treatment, new restrictions in performance of daily life roles and increased unpredictability. People goals and self-efficacy were identified as further drivers of symptom self-management. The regulation process is embedded in contextual factors.

CONCLUSION

Theory synthesis provided transparent guidance in developing a model to understand of the factors driving self-management decisions. Therefore, the model has the potential to guide development of interventions that support symptom self-management in chronic respiratory disease.

IMPACT

This newly presented conceptual model of illness-related emotional distress provides an understanding of the factors that drive self-management decisions when peoples experience new or increased symptoms. Such understanding is critical for nursing practice to developing appropriate interventions, especially in support of people decision-making.

Physical Activity Intensity is Associated with Symptom Distress in the CNICS Cohort

Symptom distress remains a challenging aspect of living with HIV. Physical activity is a promising symptom management strategy, but its effect on symptom distress has not been examined in a large, longitudinal HIV-infected cohort. We hypothesized that higher physical activity intensity would be associated with reduced symptom distress. We included 5370 people living with HIV (PLHIV) who completed patient-reported assessments of symptom distress, physical activity, alcohol and substance use, and HIV medication adherence between 2005 and 2016. The most frequent and burdensome symptoms were fatigue (reported by 56%), insomnia (50%), pain (46%), sadness (45%), and anxiety (45%), with women experiencing more symptoms and more burdensome symptoms than men. After adjusting for age, sex, race, time, HIV medication adherence, alcohol and substance use, site, and HIV RNA, greater physical activity intensity was associated with lower symptom intensity. Although individual symptoms may be a barrier to physical activity (e.g. pain), the consistent association between symptoms with physical activity suggests that more intense physical activity could mitigate symptoms experienced by PLHIV.

Understanding Symptoms of Muscle Tightness, Weakness, and Rigidity From a Nursing Perspective

PURPOSE

This study examined the nature of muscle tightness from nurses' perspectives and explored how the symptoms of muscle tightness are communicated, managed, and differentiated from other conditions, such as muscle rigidity and muscle weakness.

DESIGN

An exploratory, descriptive qualitative design was used.

METHODS

Eight rehabilitation nurses described lexicons, care strategies, and communication for muscle tightness, weakness, and rigidity.

FINDINGS

Nurses used conflicting terms to describe muscle tightness, weakness, and rigidity. They identified medications and range of motion as the best strategies to manage muscle conditions. Nurses approach care holistically and do not differentiate care strategies that are based only on a symptoms lens.

CONCLUSIONS

Nurses were unable to clearly differentiate between muscle tightness and rigidity.

CLINICAL RELEVANCE

Nurses influence patients' choice of vocabulary; therefore, they must use simple but precise terminologies to educate their patients. Miscommunication between nurses and patients can lead to errors, which can have negative consequences.

THEORY OF UNPLEASANT SYMPTOMS: CRITICAL ANALYSIS

ABSTRACT Objective: to analyze the Theory of Unpleasant Symptoms according to the model proposed by Walker and Avant. Method: a descriptive-reflexive study developed in the first half of 2016. He used the first five phases proposed by the Walker and Avant model: identification of the origins of the theory; examination of the meaning of the theory; logical adequacy; utility; degree of generalization and parsimony of theory. Results: the study allowed the reflection on the Theory of Unpleasant Symptoms, considering the multidimensionality of the symptoms and the potential stimulation between them. It was identified the relations between the main concepts used to construct the theory: physiological, psychological and situational factors, followed by performance, suffering, duration, quality, intensity and unpleasant symptoms. Conclusion: the Theory of Unpleasant Symptoms presents a structured theoretical framework, presenting logical meaning, through well-defined concepts and relations, which make possible its use in practice, teaching and nursing research.

'The Thing that Really Gets Me Is the Future': Symptomatology in Older Homeless Adults in the HOPE HOME Study

CONTEXT

The homeless population is aging. Older homeless adults experience premature development of age-related conditions and an elevated symptom burden. Little is known about symptom experience among older homeless adults.

OBJECTIVES

To characterize the experience, understanding, and management of physical, psychological, social (e.g., loneliness), and existential (e.g., regret, loss of dignity) symptoms among older homeless adults.

METHODS

We conducted semistructured interviews from June 2016 to March 2017 with a purposive sample of participants from the Health Outcomes of People Experiencing Homelessness in Older Middle Age cohort, a longitudinal study of homeless adults aged 50 and older. We analyzed data between June 2016 and December 2017 using thematic analysis.

RESULTS

We found four main themes: 1) nonphysical symptoms are interwoven with, and as distressing as, physical symptoms; 2) individuals attribute symptoms to childhood abuse, manual labor, the conditions of homelessness, and aging; 3) symptoms interfere with daily functioning, causing negative changes in personality, energy, and motivation; and 4) individuals cope with symptoms through religion, social support, and substance use.

CONCLUSION

Homelessness causes and exacerbates physical and psychological distress. Interventions should address multiple interconnected dimensions of suffering. Health systems that care for homeless patients should adapt palliative care practices using a stepwise approach. Homeless shelters should adopt policies and modifications that increase privacy and autonomy while promoting community building. Housing interventions should promote community building. All who work with people experiencing homelessness should avoid stigmatizing language and recognize homeless individuals' sources of strength and coping.

Atrial fibrillation symptom profiles associated with healthcare utilization: A latent class regression analysis

BACKGROUND

Symptoms drive healthcare use among adults with atrial fibrillation, but limited data are available regarding which symptoms are most problematic and which patients are most at-risk. The purpose of this study was to: (1) identify clusters of patients with similar symptom profiles, (2) characterize the individuals within each cluster, and (3) determine whether specific symptom profiles are associated with healthcare utilization.

METHODS

We conducted a cross-sectional secondary data analysis of 1,501 adults from the Vanderbilt Atrial Fibrillation Registry. Participants were recruited from Vanderbilt cardiology clinics, emergency department, and in-patient services. Subjects included in our analysis had clinically verified atrial fibrillation and a completed symptom survey. Symptom and healthcare utilization data were collected with the University of Toronto Atrial Fibrillation Severity Scale. Latent class regression analysis was used to identify symptom clusters, with clinical and demographic variables included as covariates. We used Poisson regression to examine the association between latent class membership and healthcare utilization.

RESULTS

Participants were predominantly male (67%) with a mean age of 58.4 years (±11.9). Four latent classes were evident, including an Asymptomatic cluster (N = 487, 38%), Highly Symptomatic cluster (N = 142, 11%), With Activity cluster (N = 326, 25%), and Mild Diffuse cluster (N = 336, 26%). Highly Symptomatic membership was associated with the greatest rate of emergency department visits and hospitalizations (incident rate ratio 2.4, P < 0.001).

CONCLUSIONS

Clinically meaningful atrial fibrillation symptom profiles were identified that were associated with increased rates of emergency department visits and hospitalizations.

The Effect of the Pain Symptom Cluster on Performance in Women Diagnosed with Advanced Breast Cancer: The Mediating Role of the Psychoneurological Symptom Cluster

BACKGROUND

Pain, depression, anxiety, sleep disturbances, and constipation were reported in different symptom clusters at different stages of breast cancer. Managing symptom clusters rather than individual symptoms can improve performance status.

AIM

The study examined the effect of pain symptom cluster (pain and constipation) on performance when mediated by the psychoneurological symptom cluster (depression, anxiety, and sleep disturbances) using age as a moderator.

DESIGN

A secondary analysis.

SETTINGS

Palliative care center at a tertiary medical center in northeast Ohio.

PARTICIPANTS

Eighty-six women diagnosed with advanced breast cancer.

METHOD

A quantitative cross-sectional approach.

RESULTS

Ordinal logistic regression showed that pain symptom cluster did not have a significant mediation effect on performance. Odds ratio indicated that subjects with pain symptom cluster were 63% more likely to be bedridden (odds ratio = 1.63, confidence interval = .69-3.84). Women who reported pain symptom cluster were 5% more likely to have psychoneurological symptom cluster (odds ratio = 1.05, confidence interval = .400-2.774). Stratified analysis of age showed no differences in performance. Post-hoc analysis showed that the components of pain symptom cluster had a significant effect on psychoneurological symptom cluster (odds ratio: 3 [1.18-7.62]).

CONCLUSIONS

Pain, constipation, depression, anxiety, and sleep disturbances were highly prevalent in women with advanced breast cancer. However, they tended to cluster in different symptom clusters. Although some findings were not significant, they all supported the direction of the tested hypotheses. Variations in symptom clusters research, including methodology, instruments, statistical tests, and chosen symptom cluster correlation coefficient, should be addressed.

Psychoeducational Intervention for Symptom Management of Fatigue, Pain, and Sleep Disturbance Cluster Among Cancer Patients: A Pilot Quasi-Experimental Study

OBJECTIVES

To assess the feasibility of conducting a trial of a psychoeducational intervention involving the provision of tailored information and coaching to improve management of a cancer-related symptom cluster (fatigue, pain, and sleep disturbance) and reduce symptom cluster impacts on patient health outcomes in the Vietnamese context and to undertake a preliminary evaluation of the intervention.

METHODS

A parallel-group single-blind pilot quasi-experimental trial was conducted with 102 cancer patients in one Vietnamese hospital. The intervention group received one face-to-face session and two phone sessions delivered by a nurse one week apart, and the comparison group received usual care. Patient outcomes were measured at baseline before the chemotherapy cycle and immediately preceding the next chemotherapy cycle. Separate linear mixed models were used to evaluate the impact of the intervention on total symptom cluster severity, symptom scores, functional status, depressive symptoms, and health-related quality of life.

RESULTS

The study design was feasible with a recruitment rate of 22.6% and attrition rate of 9.8%. Compared to the control group, the intervention group showed a significant reduction in symptom cluster severity, fatigue severity, fatigue interference, sleep disturbance, depression, and anxiety. Significant differences were not observed for pain severity, pain interference, functional status, and health-related quality of life. The intervention was acceptable to the study population, with a high attendance rate of 78% and adherence rate of 95.7%.

CONCLUSION

On the basis of the present study findings, future randomized controlled trials are needed to test the effectiveness of a symptom cluster psychoeducational intervention in Vietnam.

Exploring symptom meaning: perspectives of palliative care physicians

CONTEXT

Understanding patients' symptom experiences is essential to providing effective clinical care. The discussion between patients and physicians of symptom meaning and its significance, however, is ill understood.

OBJECTIVES

To investigate palliative care physicians' understanding of symptom meaning, and their experiences of and attitudes towards the discussion of symptom meaning with patients.

METHODS

Semi-structured interviews were conducted (N = 17) across Sydney, Australia. Transcripts were analysed using framework analysis.

RESULTS

Six key themes were identified: (1) definitions of symptom meaning (causal meanings, functional impact, existential impact, and cascade of meanings); (2) meanings are personal (demographic, culture, spiritual, and family differences); (3) eliciting meanings requires subtlety and trust (following the patient's cues); discussing meaning can be (4) hard (for the patient and health professional); (5) therapeutic (assuaging fears, feeling listened to and valued, increased sense of control, and reduced symptom distress); and (6) enhances clinicians' practice and work satisfaction (provision of more tailored care, reassurance through the provision of information, and strengthening of doctor-patient relationship).

CONCLUSIONS

Exploring symptom meaning can serve to provide information, alleviate anxiety, and facilitate individualised care, but only when patients present cues or are open to discuss symptom-related concerns. However, various barriers hinder such dialogue in consultations. Greater awareness of symptom meaning and its influence may facilitate physicians exploring symptom meaning more with patients in the future.

Symptom experience and symptom burden of patients following first-ever stroke within 1 year: a cross-sectional study

Symptoms that are multidimensional and concurrent should be assessed from different dimensions and managed together. Few studies have evaluated concurrent and multidimensional symptoms in patients with stroke. Most studies of stroke focused on dysfunctions and complications. We hypothesize that patients with stroke have a heavy symptom burden within 1 year. This study aimed to describe multidimensional and concurrent symptoms within 1 year after stroke. This study recruited 230 patients with stroke from the Rehabilitation Department of Xuhui District Center Hospital of Shanghai and the Shanghai Sunshine Rehabilitation Center in China from March to September 2017. The patients’ multidimensional symptom experience and symptom burden were analyzed using a self-made structured questionnaire and the influential factors for symptom burden were identified. The mean number of symptoms in patients with stroke was 11.7 ± 3.5. More than two thirds of the participants suffered from at least 10 co-occurring symptoms. Unilateral limb weakness had the highest prevalence and frequency. Participation restriction had the highest symptom dimensions of severity and distress. Lack of self-care ability (severity), memory deterioration (frequency), imbalance of body (distress), moodiness (distress), being unable to move limbs at will (distress), shoulder pain (distress), and slower response (frequency) were independent factors of the total symptom burden score. These findings can provide essential information for efficient symptom management of patients with stroke. This trial was registered with the ISRCTN registry (registration number: ISRCTN18421629).

Prevalence, Duration, Severity, and Distress of Chemotherapy-Related Gastrointestinal Symptoms in Patients With a Hematologic Malignancy

PURPOSE/OBJECTIVES

To describe prevalence, duration, severity, and distress of chemotherapy-related gastrointestinal (GI) symptoms, and evaluate inclusion of clinically relevant GI symptom items on cancer symptom questionnaires.
.

DESIGN

Longitudinal descriptive design.
.

SETTING

Inpatient and outpatient hematology settings.
.

SAMPLE

105 adults with a hematologic malignancy receiving their third or subsequent cycle of chemotherapy. 
.

METHODS

Participants completed weekly assessments of 19 GI symptoms during a three-week period of chemotherapy. Descriptive statistics were calculated to summarize GI symptom prevalence, duration, severity, and distress ratings at each week. Findings were compared to item content of 12 cancer multisymptom questionnaires identified in the literature.
.

MAIN RESEARCH VARIABLES

GI symptom prevalence, duration, severity, and distress.
.

FINDINGS

Participants reported an average of three to five GI symptoms at each time point that were typically experienced as mild to moderate in duration, severity, and distress. Only 3 of 11 clinically relevant GI symptoms were included on more than half of the cancer symptom questionnaires. 
.

CONCLUSIONS

Patients receiving chemotherapy experience a moderate GI symptom burden across a wide range of potential GI symptoms.
.

IMPLICATIONS FOR NURSING

Future research should include measures of clinically relevant GI symptoms that may be emerging with new cancer therapies and toxicity prevention protocols.

Evolution of the Dynamic Symptoms Model

Theories and conceptual models can be thought of as broad nets that attempt to rationalize, explain, and master a phenomenon within clinical nursing and interdisciplinary care. They can be used to guide a review of the literature and to formulate and organize research variables and relationships. Gaps in the literature can be identified and opportunities for additional research revealed (Fawcett, 2005). A variety of symptom models or theories exist, including the Theory of Symptom Management (Dodd et al., 2001), Theory of Unpleasant Symptoms (Lenz, Pugh, Milligan, Gift, & Suppe, 1997), Symptoms Experience Model (Armstrong, 2003), and Symptom Experiences in Time Theory (Henly, Kallas, Klatt, & Swenson, 2003). Most recently, the National Institute of Nursing Research identified a new National Institutes of Health Symptom Science Model to guide symptom science research (Cashion & Grady, 2015).

What is symptom meaning? A framework analysis of communication in palliative care consultations

OBJECTIVE

There is a limited understanding of symptom meaning and its significance to clinical practice within symptom experience literature. This study aims to qualitatively explore the ways in which symptom meanings are discussed by patients and responded to by palliative care physicians during consultations.

METHODS

Framework analysis was conducted with 40 palliative care consultation transcripts.

RESULTS

55% of consultations discussed symptom meaning. Six themes regarding patients' symptom meanings emerged while four themes conveyed physicians' responses to these utterances. Key symptom meanings included symptoms representing diminished function and uncertainty about symptom cause or future. Physicians usually gave scientific medical responses concerning symptom cause and treatment, versus reassurance or empathy.

CONCLUSION

This study has provided greater insight into the different symptom meanings that exist for palliative care patients. Physicians' responses highlight their reliance on medical information when patients are distressed. Future studies should explore the impact of different responses on patient outcomes, and health practitioners' views about optimal responses.

PRACTICE IMPLICATIONS

Physicians could explore symptom meanings with their patients, looking out for those identified here. Apart from information-giving and treatment, active listening to these concerns as they present in consultations may help improve the therapeutic relationship and better guide optimal care.

Distress-Based Gastrointestinal Symptom Clusters and Impact on Symptom Interference and Quality of Life in Patients with a Hematologic Malignancy Receiving Chemotherapy

BACKGROUND/SIGNIFICANCE

People with cancer can experience co-occurring related symptoms, labeled symptom clusters. Gastrointestinal (GI) symptoms are common side effects of chemotherapy, but little research has investigated GI symptom clusters. A further gap in symptom cluster research is the lack of studies reporting symptom clusters based on symptom distress ratings.

PURPOSE

To identify distress-based GI symptom clusters and to investigate their relationship to symptom interference with daily life and quality of life (QoL).

SUBJECTS

About 105 adults with hematologic malignancy receiving chemotherapy.

METHODS

On Day 1 of a cycle of chemotherapy, participants completed a modified version of the Memorial Symptom Assessment Scale assessing 30 clinically relevant symptoms, the M.D. Anderson Symptom Inventory Symptom Interference with Daily Life subscale, and the Fox Simple Quality of Life Scale. Exploratory factor analysis was used to identify distress-based symptom clusters. Symptom clusters with ≥50% GI symptoms were labeled GI symptom clusters. Linear mixed modeling explored relationships between GI symptom clusters and symptom interference with daily life and QoL.

RESULTS

Of the six distress-based symptom clusters found, the bloating cluster and appetite cluster were identified as GI symptom clusters. Both the bloating cluster and the appetite cluster were significantly related to symptom interference with daily life, but only the appetite cluster was significantly related to QoL.

CONCLUSIONS

This research demonstrates the existence of distress-based GI symptom clusters and their relationship to symptom interference and QoL. Future work should explore predictors of distress-based symptom clusters and interventions to manage them.

Advancing Symptom Science Through Symptom Cluster Research: Expert Panel Proceedings and Recommendations

An overview of proceedings, findings, and recommendations from the workshop on "Advancing Symptom Science Through Symptom Cluster Research" sponsored by the National Institute of Nursing Research (NINR) and the Office of Rare Diseases Research, National Center for Advancing Translational Sciences, is presented. This workshop engaged an expert panel in an evidenced-based discussion regarding the state of the science of symptom clusters in chronic conditions including cancer and other rare diseases. An interdisciplinary working group from the extramural research community representing nursing, medicine, oncology, psychology, and bioinformatics was convened at the National Institutes of Health. Based on expertise, members were divided into teams to address key areas: defining characteristics of symptom clusters, priority symptom clusters and underlying mechanisms, measurement issues, targeted interventions, and new analytic strategies. For each area, the evidence was synthesized, limitations and gaps identified, and recommendations for future research delineated. The majority of findings in each area were from studies of oncology patients. However, increasing evidence suggests that symptom clusters occur in patients with other chronic conditions (eg, pulmonary, cardiac, and end-stage renal disease). Nonetheless, symptom cluster research is extremely limited and scientists are just beginning to understand how to investigate symptom clusters by developing frameworks and new methods and approaches. With a focus on personalized care, an understanding of individual susceptibility to symptoms and whether a "driving" symptom exists that triggers other symptoms in the cluster is needed. Also, research aimed at identifying the mechanisms that underlie symptom clusters is essential to developing targeted interventions.

Understanding symptom experiences of muscle tightness from patients' and clinicians' perspectives

AIMS AND OBJECTIVES

The purpose of this study was to determine how patients' symptom experiences of muscle tightness correlate with examiner assessments. To address this question, we (1) obtained the vocabularies used by patients and examiners to describe muscle tightness, (2) correlated patient- reported Visual Analog Scale ratings for locations of muscle tightness on a body diagram and (3) explored the similarities and differences between patient and examiner evaluation of muscle tightness analytically and graphically.

BACKGROUND

Symptoms of muscle tightness are common complaints that occur due to musculoskeletal and neuromusculoskeletal injuries. Terms such as muscle tightness are often intermingled with other conditions including muscle tension, muscle spasticity and muscle rigidity. Discrepancies between patients and clinicians understanding of similar symptoms have been reported in the literature.

DESIGN

A concurrent exploratory mixed methods design was used.

METHOD

Fifty-seven participants (six physical therapists, 51 patients) participated. Participants provided semi-structured interviews, ratings through Visual Analog Scale and concurrently provided the words used to describe muscle tightness. Patients also provided the location of muscle tightness on a body diagram. Content analysis and hierarchical linear modelling were used for data analysis.

RESULTS

The patients' vocabularies contained more sensory and pain experiences when compared to the clinicians' vocabularies. Examiners and patients ratings were variable (standard deviation >20) and contained discrepancies. Stress played a role in the symptom experience of muscle tightness. Examiners tended to focus on patients' chief complaints, while patients reported their symptoms from a whole-body perspective.

CONCLUSIONS

Symptom experiences of muscle tightness can occur with or without pain. Use of complementary therapy and development of an objective tool that accounts for patients' sensory experiences is warranted.

RELEVANCE TO CLINICAL PRACTICE

Findings from this study indicate that in addition to all other available treatments options, nurses must also educate patients about correct posture alignment, breathing exercises and stress management.

The Situation-Specific Theory of Heart Failure Self-Care: Revised and Updated

BACKGROUND

Since the situation-specific theory of heart failure (HF) self-care was published in 2008, we have learned much about how and why patients with HF take care of themselves. This knowledge was used to revise and update the theory.

OBJECTIVE

The purpose of this article was to describe the revised, updated situation-specific theory of HF self-care.

RESULT

Three major revisions were made to the existing theory: (1) a new theoretical concept reflecting the process of symptom perception was added; (2) each self-care process now involves both autonomous and consultative elements; and (3) a closer link between the self-care processes and the naturalistic decision-making process is described. In the revised theory, HF self-care is defined as a naturalistic decision-making process with person, problem, and environmental factors that influence the everyday decisions made by patients and the self-care actions taken. The first self-care process, maintenance, captures those behaviors typically referred to as treatment adherence. The second self-care process, symptom perception, involves body listening, monitoring signs, as well as recognition, interpretation, and labeling of symptoms. The third self-care process, management, is the response to symptoms when they occur. A total of 5 assumptions and 8 testable propositions are specified in this revised theory.

CONCLUSION

Prior research illustrates that all 3 self-care processes (ie, maintenance, symptom perception, and management) are integral to self-care. Further research is greatly needed to identify how best to help patients become experts in HF self-care.

Symptom-reducing actions: a concept analysis in the context of chronic obstructive pulmonary disease

Patients with Chronic Obstructive Pulmonary Disease (COPD) have multiple symptoms. Nursing care is based on six core competencies and one of them is person-centred care that includes the aspect of professional symptom relief. The aim was to clarify a meaning of the concept of Symptom-reducing actions in the context of COPD. Databases MEDLINE and CINAHL were searched between 1982 and February 2016 and 26 publications were found. Two dictionaries and three books were investigated. The method of Walker & Avant was followed. The use of the concept of Symptom-reducing actions may be categorized by the sub-concepts of supervision, information, and patient education. Exploration of defining attributes was symptom management, instructions, support, motivation, explanation, advice, teaching, and learning. Antecedent occurrences were related to factors that affect the patient's level of function such as physical performance and cognitive function. Symptom-reducing actions offer a way to support patients with COPD in self-management. Symptom-reducing actions can mediate facts in a purposeful process performed by the nurse to enable the patient to take control over and manage unpleasant symptoms by a person-centred, planned process. The nurse can achieve this via supervision, information, and patient education with an integrated emotional component. Evaluating the outcomes is needed.

The Symptom Experience in Rectal Cancer Survivors

CONTEXT

As the number of rectal cancer survivors grows, it is important to understand the symptom experience after treatment. Although data show that rectal cancer survivors experience a variety of symptoms after diagnosis, little has been done to study the way these symptoms are grouped and associated.

OBJECTIVES

To determine symptom prevalence and intensity in rectal cancer survivors and if clusters of survivors exist, who share similar symptom-defined survivor subgroups that may vary based on antecedent variables.

METHODS

A secondary analysis of the Cancer Care and Outcomes Research and Surveillance database was undertaken. Cluster analysis was performed on 15-month postdiagnosis data to form post-treatment survivor subgroups, and these were examined for differences in demographic and clinical characteristics. Data were analyzed using cluster analysis, chi-square, and analysis of variance.

RESULTS

A total of 275 rectal cancer survivors were included who had undergone chemotherapy, radiation therapy, and surgery. Most frequently reported symptoms included feeling "worn out" (87%), feeling "tired" (85%), and "trouble sleeping" (66%). Four symptom-defined survivor subgroups (minimally symptomatic n = 40, tired and trouble sleeping n = 138, moderate symptoms n = 42, and highly symptomatic n = 55) were identified with symptom differences existing among each subgroup. Age and being married/partnered were the only two antecedents found to differ across subgroups.

CONCLUSION

This study documents differences in the symptom experience after treatment. The identification of survivor subgroups allows researchers to further investigate tailored, supportive care strategies to minimize ongoing symptoms in those with the greatest symptom burden.

Symptoms in patients with takotsubo syndrome: a qualitative interview study

OBJECTIVE

The aim of the study was to investigate the meaning of narrated symptoms in connection to takotsubo syndrome.

DESIGN, METHOD, PARTICIPANTS AND SETTING

Qualitative study consisting of 25 interviews, 23 women and 2 men aged 39-84 and living in Region Västra Götaland, Sweden. The transcribed text was analysed with phenomenological hermeneutics.

RESULTS

The interviewees reported a large number of symptoms before, during and after the acute onset of takotsubo syndrome, including pain, affected breathing, lassitude, malaise and nausea. Several of these have not been reported previously. Symptoms before the acute onset were, even if they had been prominent, ignored by the interviewees for various reasons. During the acute phase, the symptoms could no longer be ignored and the interviewees sought healthcare. The remaining residual symptom after discharge from hospital caused a great deal of worry because the interviewees feared that they would be permanent and they felt they could not live this way. On the whole, becoming ill and having a large number of symptoms greatly impacted the lives of the interviewees and made them re-evaluate how they had been living. Furthermore, they reported feeling alone and lost regarding their symptom burden, especially in relation to their residual symptoms, which affected their health and ability to return to daily life.

CONCLUSIONS

Acute symptoms, and symptoms before and after the acute ones, are a major part of the illness experience for patients with takotsubo syndrome and affect their health and well-being. Assessment of symptoms should be an integrated part of care to promote health. One way of achieving this is through the patients' own narratives of their experiences, which are an important component in person-centred care.

Selecting symptom instruments for cardiovascular populations

The purpose of this review is to provide a guide for researchers and clinicians in selecting an instrument to measure four commonly occurring symptoms (dyspnea, chest pain, palpitations, and fatigue) in cardiac populations (acute coronary syndrome, heart failure, arrhythmia/atrial fibrillation, and angina, or patients undergoing cardiac interventions). An integrative review of the literature was conducted. A total of 102 studies summarizing information on 36 different instruments are reported in this integrative review. The majority of the instruments measured multiple symptoms and were used for one population. A majority of the symptom measures were disease-specific and were multi-dimensional. This review summarizes the psychometrics and defining characteristics of instruments to measure the four commonly occurring symptoms in cardiac populations. Simple, psychometrically strong instruments do exist and should be considered for use; however, there is less evidence of responsiveness to change over time for the majority of instruments.

Clinicians' Perspectives on Managing Symptom Clusters in Advanced Cancer: A Semistructured Interview Study

CONTEXT

Managing symptom clusters or multiple concurrent symptoms in patients with advanced cancer remains a clinical challenge. The optimal processes constituting effective management of symptom clusters remain uncertain.

OBJECTIVES

To describe the attitudes and strategies of clinicians in managing multiple co-occurring symptoms in patients with advanced cancer.

METHODS

Semistructured interviews were conducted with 48 clinicians (palliative care physicians [n = 10], oncologists [n = 6], general practitioners [n = 6], nurses [n = 12], and allied health providers [n = 14]), purposively recruited from two acute hospitals, two palliative care centers, and four community general practices in Sydney, Australia. Transcripts were analyzed using thematic analysis and adapted grounded theory.

RESULTS

Six themes were identified: uncertainty in decision making (inadequacy of scientific evidence, relying on experiential knowledge, and pressure to optimize care); attunement to patient and family (sensitivity to multiple cues, prioritizing individual preferences, addressing psychosocial and physical interactions, and opening Pandora's box); deciphering cause to guide intervention (disaggregating symptoms and interactions, flexibility in assessment, and curtailing investigative intrusiveness); balancing complexities in medical management (trading off side effects, minimizing mismatched goals, and urgency in resolving severe symptoms); fostering hope and empowerment (allaying fear of the unknown, encouraging meaning making, championing patient empowerment, and truth telling); and depending on multidisciplinary expertise (maximizing knowledge exchange, sharing management responsibility, contending with hierarchical tensions, and isolation and discontinuity of care).

CONCLUSION

Management of symptom clusters, as both an art and a science, is currently fraught with uncertainty in decision making. Strengthening multidisciplinary collaboration, continuity of care, more pragmatic planning of clinical trials to address more than one symptom, and training in symptom cluster management are required.

Comparison of groups with different patterns of symptom cluster intensity across the breast cancer treatment trajectory

BACKGROUND

Comparing subgroups with different patterns of change in symptom intensity would assist in sorting out individuals at risk for more severe symptoms and worse functional outcomes.

OBJECTIVES

The objectives of this study were to identify and compare subgroups of breast cancer patients with different patterns of change in a psychoneurological symptom cluster intensity across the treatment trajectory.

METHODS

This secondary analysis used the data from 160 breast cancer patients undergoing chemotherapy or radiation treatment. Psychoneurological symptom cluster intensity was a composite score of 5 symptoms (depressed mood, cognitive disturbance, fatigue, insomnia, and pain) in a psychoneurological cluster at each of 3 time points (ie, at baseline and at 2 follow-ups after chemotherapy or radiation treatment).

RESULTS

Five distinct subgroups representing different patterns of psychoneurological symptom cluster intensity during breast cancer treatment were identified: the gradually increasing pattern subgroup (group 1), the constantly low pattern subgroup (group 2), the start low with dramatic increase and decrease pattern subgroup (group 3), the constantly high pattern subgroup (group 4), and the start high with dramatic decrease and leveling pattern subgroup (group 5). Patients without previous cancer treatment experience, with higher level of education, treated with chemotherapy, and/or with more limitations at the baseline were more likely to follow the pattern group 4. Patients in group 4 had the most serious functional limitations measured at the second follow-up time point.

CONCLUSION

The results suggest the need to evaluate interventions for specific subgroups and to examine the causal mechanisms underlying a psychoneurological symptom cluster.

IMPLICATION

Clinicians should consider these diverse symptom experiences for assessment/management.

Development of the Hirai Cancer Fatigue Scale: Testing its reliability and validity

PURPOSE

The purpose of this study was to develop the Hirai Cancer Fatigue Scale (HCFS) to assess the fatigue experienced by cancer patients, and to verify its reliability and validity.

METHODS

Based on qualitative research about the perception of fatigue by Japanese cancer patients, we developed a questionnaire. The content validity was confirmed by 5 expert oncology nurses and 5 oncologists. 281 Japanese cancer patients participated in this study. Construct validity was analyzed using factor analysis, and internal consistency was analyzed using Cronbach's α coefficient.

RESULTS

A 15-item scale with 3 dimensions, "physical/mental sensation", "activity-related sensation" and "cognitive sensation," was developed by factor analysis. This scale had an overall Cronbach's α coefficient of .943 and a test-retest reliability coefficient of r = .820 (p < 0.01), confirming the high reliability of the scale. The correlation coefficient was r = .759 (p < 0.01) between HCFS and abridged Profile of Mood States-Fatigue (POMS-F), and r = .763 (p < 0.01) between HCFS and Cancer Fatigue Scale (CFS), both showing high correlations and confirming criterion-related validity.

CONCLUSION

HCFS enables reliable and valid evaluation of Japanese cancer patients' fatigue. Use of the HCFS would assist in convenient self-evaluation of fatigue, and would allow information to be effectively provided to healthcare professionals. It could also be used for outcome evaluation in an intervention study.

Self-perception of symptoms of anemia and fatigue before and after blood transfusions in patients with myelodysplastic syndromes

PURPOSE

Myelodysplastic syndromes (MDS) constitute a heterogeneous group of clonal bone marrow disorders characterized by chronic refractory anemia. Many patients with MDS are dependent on regular blood transfusions. The study aimed to investigate symptoms of anemia and fatigue in patients with MDS immediately before and after blood transfusion and to capture patients' descriptions of their symptoms.

METHODS

Sixteen transfusion-dependent MDS patients with a median age of 74 years (range 67-91) were included. Data were collected longitudinally using the Functional Assessment of Cancer Therapy Anemia (FACT-An) questionnaire, which measured anemia and fatigue symptoms before and after one blood transfusion (day 0-4 and 7). In addition, each patient was interviewed about his or her symptoms.

RESULTS

The median total score on FACT-An increased after blood transfusion from 50 to 58 (day 0-7, p = 0.016), indicating decreased symptom burden. A positive correlation was found between increments in the FACT-An score and hemoglobin value (rs 0.66, p = 0.02). One of seven items measuring symptoms of anemia (shortness of breath) and two of 13 symptoms of fatigue (feeling fatigue and weakness) changed significantly for the better from day 0 to day 7. The interviews confirmed the FACT-An results and revealed that patients experienced severe fatigue that negatively affected the maintenance of interpersonal relationships.

CONCLUSIONS

After blood transfusion, symptoms of anemia and fatigue decreased in patients with MDS. The patients felt their symptoms had a negative impact on social life. Providing psychosocial support may contribute to improve the care of patients with transfusion-dependent MDS.
