The effect of family training and support on the quality of life and cost of hospital readmissions in congestive heart failure patients in Iran

Effects of dyadic care interventions for heart failure on patients' and caregivers' outcomes: A systematic review, meta-analysis and meta-regression

BACKGROUND

The contemporary model for managing heart failure has been extended to a patient-family caregiver dyadic context. However, the key characteristics of the model that can optimise health outcomes for both patients and caregivers remain to be investigated.

OBJECTIVES

This study aimed to identify the effects of dyadic care interventions on the behavioural, health, and health-service utilisation outcomes of patients with heart failure and their family caregivers and to explore how the intervention design characteristics influence these outcomes.

DESIGN

This study involved systematic review, meta-analysis, and meta-regression techniques.

METHODS

We performed a systematic review and meta-analysis, using 12 databases to identify randomised controlled trials or quasi-experimental studies published in English or Chinese between database inception and 31 December 2022. The considered interventions included those targeting patients with heart failure and their family caregivers to enhance disease management. Data synthesis was performed on various patient- and caregiver-related outcomes. The identified interventions were categorised according to their design characteristics for subgroup analysis. Meta-regression was performed to explore the relationship between care delivery methods and their effectiveness.

RESULTS

We identified 48 studies representing 9171 patient-caregiver dyads. Meta-analyses suggested the positive effects of dyadic care interventions on patients' health outcomes [Hedges' g (95 % confidence interval {CI}): heart failure knowledge = 1.0 (0.26, 1.75), p = 0.008; self-care confidence = 0.45 (0.08, 0.83), p = 0.02; self-care maintenance = 1.12 (0.55, 1.70), p < 0.001; self-care management = 1.01 (0.54, 1.49), p < 0.001; anxiety = -0.18 (-0.34, -0.02), p = 0.03; health-related quality of life = 0.30 (0.08, 0.51), p < 0.001; hospital admission (risk ratio {95 % CI}: hospital admission = 0.79 (0.65, 0.97), p = 0.007; and mortality = 0.58 (0.36, 0.93), p = 0.02)]. Dyadic care interventions also improved the caregivers' outcomes [Hedges' g (95 % CI): social support = 0.67 (0.01, 1.32), p = 0.05; perceived burden = -1.43 (-2.27, -0.59), p < 0.001]. Although the design of the identified care interventions was heterogeneous, the core care components included enabling and motivational strategies to improve self-care, measures to promote collaborative coping within the care dyads, and nurse-caregiver collaborative practice. Incorporating the first two core components appeared to enhance the behavioural and health outcomes of the patients, and the addition of the last component reduced readmission. Interventions that engaged both patients and caregivers in care provision, offered access to nurses, and optimised continuity of care led to better patient outcomes.

CONCLUSIONS

These findings demonstrate that dyadic care interventions can effectively improve disease management in a family context, resulting in better health outcomes for both patients and caregivers. Additionally, this study provides important insights into the more-effective design characteristics of these interventions.

Psychosocial interventions and mental health in patients with cardiovascular diseases living in low- and middle-income countries: A systematic review and meta-analysis

OBJECTIVE

Mental health issues are closely associated with symptoms and outcomes of cardiovascular diseases (CVDs). The magnitude of this problem is alarmingly high in low and middle-income countries (LMICs). This systematic review and meta-analysis aimed to examine the effectiveness of psychosocial interventions on mental health outcomes among patients with CVDs living in LMICs.

METHODS

This review includes Randomized controlled trials (RCTs) and quasi-experimental studies conducted on adult patients who had a CVD and/or hypertension and located in LMICs. Studies published in English between 2010 and March, 2021 and which primarily reported mental health outcomes of resilience, self-efficacy, Quality of life (QoL), depression and anxiety were included. Studies were screened, extracted and critically appraised by two independent reviewers. Meta-analysis was conducted for RCTs and narrative summaries were conducted for all other studies. PRISMA guidelines were followed for reporting review methods and findings.

RESULTS

109 studies included in this review reported educational, nursing, behavioral and psychological, spiritual, relaxation, and mindfulness interventions provided by multidisciplinary teams. 14 studies reported self-efficacy, 70 reported QoL, 62 reported one or both of anxiety and depression, and no study was found that reported resilience as an outcome in this population. Pooled analysis showed improvements in self-efficacy and QoL outcomes. The majority of studies showed improvement in outcomes, though the quality of the included studies varied.

CONCLUSION

Patients with CVDs in LMICs may experience improved mental health through the use of diverse psychosocial interventions. Evaluations are needed to investigate whether the impact of interventions on mental health are sustained over time.

Social network interventions to support cardiac rehabilitation and secondary prevention in the management of people with heart disease

BACKGROUND

Globally, cardiovascular diseases (CVD, that is, coronary heart (CHD) and circulatory diseases combined) contribute to 31% of all deaths, more than any other cause. In line with guidance in the UK and globally, cardiac rehabilitation programmes are widely offered to people with heart disease, and include psychosocial, educational, health behaviour change, and risk management components. Social support and social network interventions have potential to improve outcomes of these programmes, but whether and how these interventions work is poorly understood.  OBJECTIVES: To assess the effectiveness of social network and social support interventions to support cardiac rehabilitation and secondary prevention in the management of people with heart disease. The comparator was usual care with no element of social support (i.e. secondary prevention alone or with cardiac rehabilitation).  SEARCH METHODS: We undertook a systematic search of the following databases on 9 August 2022: CENTRAL, MEDLINE, Embase, and the Web of Science. We also searched ClinicalTrials.gov and the WHO ICTRP. We reviewed the reference lists of relevant systematic reviews and included primary studies, and we contacted experts to identify additional studies.  SELECTION CRITERIA: We included randomised controlled trials (RCTs) of social network or social support interventions for people with heart disease. We included studies regardless of their duration of follow-up, and included those reported as full text, published as abstract only, and unpublished data.

DATA COLLECTION AND ANALYSIS

Using Covidence, two review authors independently screened all identified titles. We retrieved full-text study reports and publications marked 'included', and two review authors independently screened these, and conducted data extraction. Two authors independently assessed risk of bias, and assessed the certainty of the evidence using GRADE. Primary outcomes were all-cause mortality, cardiovascular-related mortality, all-cause hospital admission, cardiovascular-related hospital admission, and health-related quality of life (HRQoL) measured at > 12 months follow-up.  MAIN RESULTS: We included 54 RCTs (126 publications) reporting data for a total of 11,445 people with heart disease. The median follow-up was seven months and median sample size was 96 participants. Of included study participants, 6414 (56%) were male, and the mean age ranged from 48.6 to 76.3 years. Studies included heart failure (41%), mixed cardiac disease (31%), post-myocardial infarction (13%), post-revascularisation (7%), CHD (7%), and cardiac X syndrome (1%) patients. The median intervention duration was 12 weeks. We identified notable diversity in social network and social support interventions, across what was delivered, how, and by whom.  We assessed risk of bias (RoB) in primary outcomes at > 12 months follow-up as either 'low' (2/15 studies), 'some concerns' (11/15), or 'high' (2/15). 'Some concerns' or 'high' RoB resulted from insufficient detail on blinding of outcome assessors, data missingness, and absence of pre-agreed statistical analysis plans. In particular, HRQoL outcomes were at high RoB. Using the GRADE method, we assessed the certainty of evidence as low or very low across outcomes. Social network or social support interventions had no clear effect on all-cause mortality (risk ratio (RR) 0.75, 95% confidence interval (CI) 0.49 to 1.13, I2 = 40%) or cardiovascular-related mortality (RR 0.85, 95% CI 0.66 to 1.10, I2 = 0%) at > 12 months follow-up. The evidence suggests that social network or social support interventions for heart disease may result in little to no difference in all-cause hospital admission (RR 1.03, 95% CI 0.86 to 1.22, I2 = 0%), or cardiovascular-related hospital admission (RR 0.92, 95% CI 0.77 to 1.10, I2 = 16%), with a low level of certainty. The evidence was very uncertain regarding the impact of social network interventions on HRQoL at > 12 months follow-up (SF-36 physical component score: mean difference (MD) 31.53, 95% CI -28.65 to 91.71, I2 = 100%, 2 trials/comparisons, 166 participants; mental component score MD 30.62, 95% CI -33.88 to 95.13, I2 = 100%, 2 trials/comparisons, 166 participants).  Regarding secondary outcomes, there may be a decrease in both systolic and diastolic blood pressure with social network or social support interventions. There was no evidence of impact found on psychological well-being, smoking, cholesterol, myocardial infarction, revascularisation, return to work/education, social isolation or connectedness, patient satisfaction, or adverse events.  Results of meta-regression did not suggest that the intervention effect was related to risk of bias, intervention type, duration, setting, and delivery mode, population type, study location, participant age, or percentage of male participants.  AUTHORS' CONCLUSIONS: We found no strong evidence for the effectiveness of such interventions, although modest effects were identified in relation to blood pressure. While the data presented in this review are indicative of potential for positive effects, the review also highlights the lack of sufficient evidence to conclusively support such interventions for people with heart disease. Further high-quality, well-reported RCTs are required to fully explore the potential of social support interventions in this context. Future reporting of social network and social support interventions for people with heart disease needs to be significantly clearer, and more effectively theorised, in order to ascertain causal pathways and effect on outcomes.

CROSS-CULTURAL ADAPTATION AND VALIDATION OF THE PERSIAN VERSION OF THE FAMILY FUNCTIONING, HEALTH, AND SOCIAL SUPPORT QUESTIONNAIRE IN A SAMPLE OF HEART FAILURE PATIENTS AND THEIR FAMILY MEMBERS

Background and Purpose: Family functioning, family health, and social support have significant roles in the management of heart failure (HF). This study aimed to translate, adapt, and assess the validity and reliability of the Persian version of the Family Functioning, Family Health, and Social Support (FAFHES) questionnaire. Methods: FAFHES questionnaire was translated into Persian, and an expert panel assessed the cross-cultural adaptation. We examined the construct validity by confirmatory factor analysis and internal consistency by Cronbach's alpha coefficients among 576 participants. Results: The Persian FAFHES confirmed the three-factor structure in the social support and the five-factor structure in the family health scales. However, the family functioning scale yielded the three-factor structure versus the four-factor structure in the original scales. The Cronbach's alpha for the three scales varied from 0.85 to 0.94. Conclusions: The adapted FAFHES seems to be valid and reliable to measure family functioning, family health, and social support in families with HF.

Nurse-led heart failure educational interventions for patient and informal caregiver dyads: An integrative review

BACKGROUND

Heart failure is a major health problem with significant economic burden in the United States. Educating heart failure dyads (heart failure patient and informal caregiver) is a relatively new domain and is being proposed by providers, policy makers, and third-party payors. Nurse-led dyad education can improve quality of life and reduce hospital admissions in the heart failure population.

OBJECTIVES

This integrative literature review focused on evaluating design, delivery content, and outcomes of nurse-led dyadic educational interventions.

METHODS

PubMed, CINAHL, Cochrane, and Google Scholar databases (1999 -2022) were searched for quantitative and qualitative studies that included these search terms: heart failure, dyads, nonmedical caregivers, caregivers, randomized controlled trials, nurse-led education, education.

RESULTS

The search yielded 92 articles. The results included seven randomized controlled trials and one pilot study conducted from 2005 to 2017. Sample sizes ranged from 20 to 155 dyads. Dyads who received education interventions had positive outcomes. Face-to-face coaching provided stronger outcomes. Interventions varied in length from baseline to three months, with post-intervention follow-ups from one to 12 months.

CONCLUSIONS

A paucity of studies of nurse-led heart failure dyadic educational interventions have been reported in the literature. To advance the science and decrease heart failure readmissions, greater efforts to study and incorporate education and support for heart failure dyads is needed, along with assessment of both patient and caregiver outcomes.

Systematic Review of Dyadic Interventions for Ambulatory Care Sensitive Conditions: Current Evidence and Key Gaps

OBJECTIVES

Identify non-pharmacological interventions to support patient/caregiver dyads with ACSCs; review the effects of dyadic interventions on health services outcomes; and review the effectiveness of dyadic interventions on patient and caregiver biopsychosocial outcomes.

METHODS

A systematic review of randomized controlled trials (RCTs).

RESULTS

Twenty-six manuscripts representing 20 unique RCTs (Mean N = 154 patients, 140 caregivers) were eligible. Eleven RCTs examined caregiving in patients with HF, seven with T2DM, one with COPD, and one with mixed ACSCs. Dyadic interventions for ACSCs were diverse in terms of length and content, with most including an educational component. Only 4/26 included studies had a low risk of bias. Interventions were most successful at improving quality of life, clinical health outcomes, health behaviors, and health services outcomes, with fewer improvements in patient mental health outcomes, psychosocial outcomes, relationship outcomes, and caregiver outcomes in general. The largest effect sizes were reported from trials focused on T2DM.

CONCLUSIONS

High-quality research with consistent measuring instruments is needed to understand which interventions are associated with improved patient and caregiver outcomes.

CLINICAL IMPLICATIONS

There may be clinically relevant benefits to including caregivers in interventions for patients with ACSCs, and clinicians should consider this when devising treatment plans.

Comparing the Effects of Gamification and Teach-Back Training Methods on Adherence to a Therapeutic Regimen in Patients After Coronary Artery Bypass Graft Surgery: Randomized Clinical Trial

Background

Patients undergoing coronary artery bypass graft surgery (CABGS) may fail to adhere to their treatment regimen for many reasons. Among these, one of the most important reasons for nonadherence is the inadequate training of such patients or training using inappropriate methods.

Objective

This study aimed to compare the effect of gamification and teach-back training methods on adherence to a therapeutic regimen in patients after CABGS.

Methods

This randomized clinical trial was conducted on 123 patients undergoing CABGS in Tehran, Iran, in 2019. Training was provided to the teach-back group individually. In the gamification group, an app developed for the purpose was installed on each patient’s smartphone, with training given via this device. The control group received usual care, or routine training. Adherence to the therapeutic regimen was assessed using a questionnaire on adherence to a therapeutic regimen (physical activity and dietary regimen) and an adherence scale as a pretest and a 1-month posttest.

Results

One-way analysis of variance (ANOVA) for comparing the mean scores of teach-back and gamification training methods showed that the mean normalized scores for the dietary regimen (P<.001, F=71.80), movement regimen (P<.001, F=124.53), and medication regimen (P<.001, F=9.66) before and after intervention were significantly different between the teach-back, gamification, and control groups. In addition, the results of the Dunnett test showed that the teach-back and gamification groups were significantly different from the control group in all three treatment regimen methods. There was no statistically significant difference in adherence to the therapeutic regimen between the teach-back and control groups.

Conclusions

Based on the results of this study, the use of teach-back and gamification training approaches may be suggested for patients after CABGS to facilitate adherence to the therapeutic regimen.

The of effect of partnership-based education on adherence to the treatment plans in open heart surgery

BACKGROUND

Adherence to the treatment plans is one of the most effective conducts to prevent and reduce postoperative side effects. Partnership-based education is one of the most efficient ways to shape health behaviors. The aim of the present study was to determine the effect of partnership-based education on adherence to the treatment plans in open heart surgery.

MATERIALS AND METHODS

This quasi-experimental study was conducted in 2019-2020 on the patients undergoing open heart surgery in Tehran (Capital of Iran). Sampling was done in one educational hospital. A total of 86 patients and their caregivers participated in the study. Sampling was done nonrandomly by tossing a coin, and patients were allocated into the odd week in the intervention group and the even week in the control group (n = 43 in each group), and data were collected before and after intervention using the Treatment Adherence Questionnaire concerning dietary, physical activity, and medication aspects. The educational intervention was carried out after the pretest analysis in five 20-45 min sessions (two individual and three group educations). Data were analyzed with Chi-square, independent t-test, and paired t-test using SPSS 19 at a significance level of P < 0.05.

RESULTS

Patients and caregivers in both groups did not have a significant difference in terms of demographic variables (P > 0. 05). In addition, there was no significant difference in the mean of dietary, physical activity, and medication plans before the intervention in both groups; however, after the intervention, the mean of the three aspects in the intervention group was significantly higher than that of control (P < 0.001).

CONCLUSION

Implementing partnership-based education with participation of patients and caregivers is influential in improving patients' adherence to the treatment plans and it is recommended as a clinical dynamic educational strategy.

Effects of the Older Family Network Program on Improving Quality of Life Among Older Adults in Thailand

BACKGROUND

The evidence of promoting family members' health care for older adults by applying family networks and theory of planned behavior will lead to mental health and lower the quality of life among older adults in rural community in Thailand is unclear.

OBJECTIVE

The study aimed to assess the effects of health promotion among older adults using an aging family network program to reduce depression and improve quality of life (QOL) among older adults.

PATIENTS AND METHODS

This quasi-experimental study was enrolled on one hundred and ten older adults and their family members. Fifty-five older adult participants joined the health promoting program using family member involvement. This program trained them to change health behaviors such as eating healthy food, exercising, emotion management and disability preventive activities to reduce dementia, stroke and falls. The program was conducted in a rural community for 12 months. A comparison group program conducted usual health promoting activities by health personnel. They evaluated quality of life (QOL) using WHOQOL-OLD measurement, and 30-item geriatric depression scale before implementing interventions and after interventions at 9th and 12th months. Data were analyzed using general linear mixed model analysis.

RESULTS

After the intervention, social support and perception of health care from family members were significantly improved at the 9th month. At the 12th month, overall QOL, sensory ability, social participation, intimacy, social support, and perception of health care from family members significantly improved. Depression was also reduced at the 12th month.

CONCLUSION

These findings demonstrated that health promotion using family members improved QOL and reduced depression long term. Policymakers should implement programs to improve QOL among older adults. They need to improve the involvement of family members when conducting health promotion among older adults and support funding due to conduct on weekends or in the evening.

The Effect of Family-Centered Supportive Program on Chemotherapy-Induced Symptoms in Patients with Acute Lymphoblastic Leukemia (ALL)

Background: Acute lymphoblastic leukemia is a disease of the hematopoietic system and chemotherapy is recommended as the primary treatment. As many chemotherapeutic agents have severe adverse effects, patients require to be supported by their family to deal with chemotherapy-related symptoms. This study attempted to investigate the effect of family-centered supportive programs on chemotherapy symptom control in patients with acute lymphoblastic leukemia. Materials and Methods: Sixty-six patients with acute lymphoblastic leukemia undergoing chemotherapy along with their caregivers participated in this nonrandomized clinical trial. Patients in Shariati and Taleghani Hospital were assigned to intervention (n=33) and control group (n=33), respectively. A survey of family-centered supportive program was conducted via in-person and telephone up to 6 cycles of chemotherapy. The chemotherapy symptom assessment scale was administered to record the data during 6 cycles of chemotherapy treatment. The control group only received routine interventions. Data were analyzed using Chi-square and Mann-Whitney U tests. Results: The results of the study indicated that there was a statistically significant difference in terms of the frequency of 9 chemotherapy-induced symptoms including nausea, shortness of breath, problems related to skin and nails, a sore/sensitive mouth or throat, anorexia, weight gain or loss, headache and sore/scratchy/dry eyes between the control and intervention group. There was also a statistically significant difference in the severity and level of discomfort of 19 chemotherapy-induced symptoms between the control and intervention group. Conclusion: Family-centered supportive program can be considered as an approach to decrease the frequency, severity and discomfort level of chemotherapy-induced symptoms.

Study of potentially preventable hospitalisations (PPH) for chronic conditions: what proportion are preventable and what factors are associated with preventable PPH?

INTRODUCTION

The proportion of potentially preventable hospitalisations (PPH) which are actually preventable is unknown, and little is understood about the factors associated with individual preventable PPH. The Diagnosing Potentially Preventable Hospitalisations (DaPPHne) Study aimed to determine the proportion of PPH for chronic conditions which are preventable and identify factors associated with chronic PPH classified as preventable.

SETTING

Three hospitals in NSW, Australia.

PARTICIPANTS

Community-dwelling patients with unplanned hospital admissions between November 2014 and June 2017 for congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), diabetes complications or angina pectoris. Data were collected from patients, their general practitioners (GPs) and hospital records.

OUTCOME MEASURES

Assessments of the preventability of each admission by an Expert Panel.

RESULTS

323 admissions were assessed for preventability: 46% (148/323) were assessed as preventable, 30% (98/323) as not preventable and 24% (77/323) as unclassifiable. Statistically significant differences in proportions preventable were found between the three study sites (29%; 47%; 58%; p≤0.001) and by primary discharge diagnosis (p≤0.001).Significant predictors of an admission being classified as preventable were: study site; final principal diagnosis of CHF; fewer diagnoses on discharge; shorter hospital stay; GP diagnosis of COPD; GP consultation in the last 12 months; not having had a doctor help make the decision to go to hospital; not arriving by ambulance; patient living alone; having someone help with medications and requiring help with daily tasks.

CONCLUSIONS

That less than half the chronic PPH were assessed as preventable, and the range of factors associated with preventability, including site and discharge diagnosis, are important considerations in the validity of PPH as an indicator. Opportunities for interventions to reduce chronic PPH include targeting patients with CHF and COPD, and the provision of social welfare and support services for patients living alone and those requiring help with daily tasks and medication management.

The Impact of Nurse-Led Cardiac Rehabilitation on Quality of Life and Biophysiological Parameters in Patients With Heart Failure: A Randomized Clinical Trial

BACKGROUND

Cardiovascular diseases are the leading cause of mortality in the Indian subcontinent, accounting for 38% of deaths annually. One cardiovascular disease in particular, heart failure, is a growing public health problem both in India and worldwide.

PURPOSE

Heart failure is a chronic, progressive disease with increasing rates of incidence and prevalence. This study was conducted to determine the influence of a nurse-led cardiac rehabilitation program on quality of life and biophysiological parameters in patients with chronic heart failure. In this study, it was hypothesized that participants in the cardiac rehabilitation program would report significantly more-positive changes in quality of life and biophysiological parameters than their peers who did not participate in this program.

METHODS

In this randomized controlled trial, the participants were patients with chronic heart failure who had been admitted to a tertiary care hospital in India. The participants assigned to the intervention group received both nurse-led cardiac rehabilitation and routine care. In addition, intervention group participants received a booklet on cardiac rehabilitation, Healthy Way to Healthy Heart, at discharge and fortnightly telephone reminders about good cardiac rehabilitation practices. A standard questionnaire was used to collect targeted information on participants' general and disease-specific quality of life at 1 and 3 months postintervention. Biophysiological parameters such as body mass index, blood pressure, and serum cholesterol values were also measured.

RESULTS

Two thirds of the participants in each group (65% in the intervention group and 66% in the control group) were between 51 and 70 years old. The mean score for the mental component summary of generic quality of life steadily decreased in the control group and steadily increased in the intervention group at the first and second posttests.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

Nurses working in cardiology units play a pivotal role in educating and managing the health status of patients with heart failure. Providing cardiac rehabilitation to patients with heart failure benefits the quality of life of these patients. Nurses working in cardiology units should encourage patients with heart failure to practice cardiac rehabilitation for a longer period to further improve their quality of life.

Cost-utility analysis of home-based cardiac rehabilitation as compared to usual post-discharge care: systematic review and meta-analysis of randomized controlled trials

INTRODUCTION

Determining cost-utility differences between home-based cardiac rehabilitation (HBCR) on the one hand, and usual post-discharge care (UC) on the other, can improve resource-allocation in healthcare settings.

AREAS COVERED

In June 2019, PubMed, Web of Science, Scopus, and Cochrane library were searched for randomized controlled HBCR trials. Standardized mean differences (SMDs) of cost and quality-adjusted life years (QALYs) between HBCRs and UCs were calculated using random effect models. Heterogeneity was assessed by inconsistency index (I2) and publication bias by funnel plot and Egger's regression test. Thirteen articles, representing 2,992 participants, were deemed representative for final analysis. In the meta-analysis, a significant difference with respect to QALYs favored HBCR, while no significant cost difference was observed between HBCR and UC. However, subgroup-analysis of trials with different follow-up durations revealed somewhat different results, and HBCR was found to be significantly better with regard to both cost and QALYs for patients with heart failure. Cost-utility analysis categorizing interventions as 'dominant', 'effective', 'doubtful', and 'dominated', found HBCRs dominant.

EXPERT OPINION

Although HBCR tended to be superior compared to UC in this review, larger and more robust trials addressing specific patients groups are needed for definitive results.

Dyadic effects of perceived social support on family health and family functioning in patients with heart failure and their nearest relatives: Using the Actor-Partner Interdependence Mediation Model

Background

Social support, family functioning and family health are essential elements in the treatment of heart failure, yet most heart failure studies focus on the pharmacological interventions. This study aimed to examine whether perceived social support from nurses is associated with better family functioning of patients with heart failure and their nearest relatives and to examine whether family health mediates this relationship.

Methods and findings

A sample of 312 patients with heart failure and 312 of their nearest relatives were included in the study. The Family Functioning, Health and Social Support questionnaire was used to collect the data. Dyadic data were analysed by the Actor–Partner Interdependence Mediation Model with distinguishable dyads using structural equation modelling. Patients and nearest relatives who perceived more social support had a higher level of family health and functioned better within the family. One partner effect was found, indicating that the higher the level of family health of the nearest relative, the better the family functioning of the patient (p <0.001). Family health partially (in the patient) and completely (in the nearest relative) mediated the association between social support and family functioning.

Conclusion

This study indicated that patients with heart failure and their nearest relatives who perceived more social support from nurses were more likely to have high level of family health and function better within the family. The interdependent relationships found in our study highlight a dyadic and family-oriented approach to improve family functioning in patients with heart failure.

Estimation of Mean Intelligence Quotient with Wechsler Scale in Iran: Systematic Review and Meta-Analysis

The low intelligence quotient (IQ) level is one of the most common and important medical, social, and familial problems in all countries. The current study aimed to estimate mean IQ with the Wechsler scale in Iran by performing a systematic review and meta-analysis. In the current meta-analysis, all articles related to IQ conducted in Iran using the Wechsler scale were deeply searched by reviewing citation databases including Science Direct, PubMed, Scopus, Web of Science, Springer, SID, Magiran, Iranmedex, Medlib, and Google Scholar motor search and using valid keywords without time limits. Due to heterogeneity between studies, a random effects model was used to combine the results of studies. To investigate the heterogeneity of the studies, the I2 index was used. All statistical analyses were performed using STATA software version 11.1. The number of participants in the 51 studies was 5352. The mean total IQ score in Iran was estimated 97.12 (95% confidence interval [CI]: 88.71-105.52), the practical intelligence was 92.84 (95% CI: 79.14-106.55), and the verbal intelligence was 94.50 (95% CI: 83.90-105.10). The total IQ score in the northern, southern, central, eastern, and western regions of Iran was 97.08, 108.90, 92.31, 101.76, and 96.45, respectively. The mean IQ score in Iran in subjects under 20 years of age is 97.73 and in subjects over 20 years of age is 105.61. There is also no significant relationship between the mean total IQ in Iran and two parameters of the year of research and number of research samples. For prevention of decrease IQ and given that proper nutrition and breastfeeding directly contribute to increase IQ, nutrition should be provided free of charge in poorer areas during pregnancy until baby born. Moreover, the media should provide adequate education for breastfeeding and nutrition, because IQ affects people's academic, occupational, personal, and social performance, and also prevents elite immigration with suitable planning and provides conditions for elites to return to the country.

Effectiveness of revascularization interventions compared with medical therapy in patients with ischemic cardiomyopathy: A systematic review protocol

BACKGROUND

Cardiomyopathies is a group of heart diseases that directly affects the heart muscle, and their causes is not just high blood pressure, congenital and pericardial diseases but ischemic cardiomyopathy disease are also caused by vascular disorders, and to confirm the diagnosis, angiography is required. There are several methods for treating and controlling ischemic cardiomyopathy in world health systems and especially in the Iran health system, which include medical treatment, percutaneous coronary intervention (PCI), and coronary artery bypass graft (CABG).

METHODS

This systematic review will includes observational and interventional studies in English and Persian languages and evaluates effectiveness of revascularization interventions and medical therapy in patients with ischemic cardiomyopathy. Animal studies will not be considered. In this systematic review, our sources of information will be electronic databases, trial registries, and different types of grey literature. An electronic search is performed through PubMed, Cochrane library, Scopus, Web of Science, EMBASE, Tufts Medical Center Cost-Effectiveness Analysis Registry, NHS Economic Evaluations Database. To integrate the results of studies with similar results, meta-analysis will be used, for which Comprehensive Meta-Analysis (CMA) software will be used. Results are provided using relative risk with a 95% confidence interval for information.

RESULTS

The results of this systematic review will be published in a peer-reviewed journal.

CONCLUSION

To our knowledge, this systematic review will be the first to evaluate existing research on the effectiveness of revascularization interventions compared with medical therapy in patients with ischemic cardiomyopathy. The review will benefit patients, healthcare providers, and policymakers.

Progressive exhaustion: A qualitative study on the experiences of Iranian family caregivers regarding patients undergoing hemodialysis

Objective

The aim of this study was to explore the burden of care for patients undergoing hemodialysis from the experiences of family caregivers.

Methods

In this qualitative study, a content analysis approach was used for data collection and analysis. Participants were 16 family caregivers selected through purposive sampling from four medical education centers affiliated with Ahvaz Jundishapur University of Medical Sciences, Iran. Semi-structured interviews were held to collect data.

Results

Four categories were developed as follows: ‘care challenges’, ‘psychological vulnerabilities’, ‘the chronic nature of care ’and “care in the shade”. The categories led to the development of the main theme of ‘progressive exhaustion’ experienced by the family caregivers during the provision of care to patients undergoing hemodialysis.

Conclusion

Family caregivers have a significant role in the process of patient care, and this role leads them to progressive exhaustion; therefore, the overall health of the caregivers should be taken into account and more attention should be paid to their quality of life, social welfare, and satisfaction level.

A systematic review of heart failure dyadic self-care interventions focusing on intervention components, contexts, and outcomes

BACKGROUND

Having support from an informal carer is important for heart failure patients. Carers have the potential to improve patient self-care. At the same time, it should be acknowledged that caregiving could affect the carer negatively and cause emotional reactions of burden and stress. Dyadic (patient and informal carer) heart failure self-care interventions seek to improve patient self-care such as adherence to medical treatment, exercise training, symptom monitoring and symptom management when needed. Currently, no systematic assessment of dyadic interventions has been conducted with a focus on describing components, examining physical and delivery contexts, or determining the effect on patient and/or carer outcomes.

OBJECTIVE

To examine the components, context, and outcomes of dyadic self-care interventions.

DESIGN

A systematic review registered in PROSPERO, following PRISMA guidelines with a narrative analysis and realist synthesis.

DATA SOURCES

PubMed, EMBASE, Web of Science, PsycINFO, and Cochrane Central Register of Controlled Trials were searched using MeSH, EMTREE terms, keywords, and keyword phrases for the following concepts: dyadic, carers, heart failure and intervention. Eligible studies were original research, written in English, on dyadic self-care interventions in adult samples.

REVIEW METHODS

We used a two-tiered analytic approach including both completed studies with power to determine outcomes and ongoing studies including abstracts, small pilot studies and protocols to forecast future directions.

RESULTS

Eighteen papers - 12 unique, completed intervention studies (two quasi- and ten experimental trials) from 2000 to 2016 were reviewed. Intervention components fell into three groups - education, support, and guidance. Interventions were implemented in 5 countries, across multiple settings of care, and involved 3 delivery modes - face to face, telephone or technology based. Dyadic intervention effects on cognitive, behavioral, affective and health services utilization outcomes were found within studies. However, findings across studies were inconclusive as some studies reported positive and some non-sustaining outcomes on the same variables. All the included papers had methodological limitations including insufficient sample size, mixed intervention effects and counter-intuitive outcomes.

CONCLUSIONS

We found that the evidence from dyadic interventions to promote heart failure self-care, while growing, is still very limited. Future research needs to involve advanced sample size justification, innovative solutions to increase and sustain behavior change, and use of mixed methods for capturing a more holistic picture of effects in clinical practice.

Comparison of Effect of Lavandula officinalis and Venlafaxine in Treating Depression: A Double Blind Clinical Trial

INTRODUCTION

Major depressive disorder is a chronic disease which may be associated with other mental illnesses. Lavandula officinalis and venlafaxine, herbal and chemical drugs respectively, are used to treat depression. Despite pharmacotherapy, major depressive disorder has a complicated pattern of resistance and recurrence.

AIM

The aim of this study was to determine the effect of L. officinalis and venlafaxine in treating depression.

MATERIALS AND METHODS

For this study, 120 patients referred to the psychiatry clinic of the Shahrekord University of Medical Sciences, Shahrekord, Iran, were randomly selected. The participants were randomly assigned to three groups: venlafaxine (Control Group), venlafaxine + L. officinalis (L. officinalis Group), and venlafaxine + placebo (Placebo Group). All the patients underwent treatment for six weeks. Depression test was administered to the three groups at different time intervals before the treatment, four weeks after the treatment and at completion of the treatment. The data were analysed by SPSS version17.0.

RESULTS

Depression scores of all the groups decreased over time (p=0.001). The depression scores were significantly different between the control and L. officinalis groups (p=0.004), and the control and placebo groups (p=0.002), but were not significantly different between the L. officinalis and placebo groups (p=0.95).

CONCLUSION

Adding L. officinalis or a placebo is equally effective in decreasing mean depression score and venlafaxine obviously decreased this score.

Study of Association of Substance Use Disorders with Family Members' Psychological Disorders

INTRODUCTION

Substance Use Disorders (SUDs) represents a serious problem in Iranian community that may lead to psychological disorders in families.

AIM

This study was conducted to investigate the association of SUDs with family members' psychological disorders.

MATERIALS AND METHODS

The sample size of the study consisted of 724 people referred to a counseling and psychology clinic in Shahrekord, southwest Iran. For data gathering, random method was adopted. After the relationship was established with the patients during the counseling and their confidence was gained, development of SUDs and related effect on the referred patient's family members were investigated by a pre-developed checklist. The statistical tests used to analyse the data were chi-square, Fisher's exact test, and odds ratio.

RESULTS

The most frequent disorder noted was depression (40.5%) followed by generalized anxiety disorder (21%), minor interpersonal and children's behavioural problems (15%), and hysteria (8%). Depression, hysteria, and minor interpersonal and children's behavioural problems in the women and men were reported 48% vs. 20%, 9% vs. 5%, and 10% vs. 27%, respectively. A significant association was seen between SUDs in the patients' spouses and children as well as in their families, and gender, marital status, and occupation, but not place of residence and education.

CONCLUSION

An association was seen between the psychiatric disorders in the people referring the studied center and SUDs in their families. Addiction in family plays an important role in developing or recurring psychiatric disorders in other family members.

Commitment to care: the most important coping strategies among family caregivers of patients undergoing haemodialysis

BACKGROUND

Caregivers of patients undergoing haemodialysis often experience an intensive burden of care; therefore, it is important to understand the type of strategies that are used by caregivers to adapt and to commit themselves to caring for another individual.

AIM

The aim of this study was to explore the specific coping strategies used by family caregivers of patients undergoing haemodialysis.

METHODS

In this qualitative study, 16 family caregivers of patients undergoing haemodialysis were selected through purposive sampling in four dialysis centres in south of Iran. Semi-structured interviews were used to collect data. A content analysis of the interviews was performed to determine relevant themes.

RESULTS

Data analysis resulted in the emergence of four categories including 'cultural and religious constructs', 'sense of responsibility', 'self-restraint' and 'satisfactory caring', as whole of these categories are included in the main theme of 'commitment to care' which is experienced by the family caregivers during the care of patients undergoing haemodialysis.

CONCLUSIONS

This study demonstrates that coping strategies stemming from the cultural beliefs of caregivers are very salient in their commitment to care; thus, the health-care team, especially nurses, should encourage family caregivers to use these strategies to maintain their physical and psychological health and to provide quality care for patients.

A Comparison of the Effects of Pilates and McKenzie Training on Pain and General Health in Men with Chronic Low Back Pain: A Randomized Trial

Background:

Today, chronic low back pain is one of the special challenges in healthcare. There is no unique approach to treat chronic low back pain. A variety of methods are used for the treatment of low back pain, but the effects of these methods have not yet been investigated adequately.

Aim:

The aim of this study was to compare the effects of Pilates and McKenzie training on pain and general health of men with chronic low back pain.

Materials and Methods:

Thirty-six patients with chronic low back pain were chosen voluntarily and assigned to three groups of 12 each: McKenzie group, Pilates group, and control group. The Pilates group participated in 1-h exercise sessions, three sessions a week for 6 weeks. McKenzie group performed workouts 1 h a day for 20 days. The control group underwent no treatment. The general health of all participants was measured by the General Health Questionnaire 28 and pain by the McGill Pain Questionnaire.

Results:

After therapeutic exercises, there was no significant difference between Pilates and McKenzie groups in pain relief (P = 0.327). Neither of the two methods was superior over the other for pain relief. However, there was a significant difference in general health indexes between Pilates and McKenzie groups.

Conclusion:

Pilates and McKenzie training reduced pain in patients with chronic low back pain, but the Pilates training was more effective to improve general health.

Effect of Sleep Hygiene Education on Sleep Quality in Hemodialysis Patients

INTRODUCTION

Sleep is referred a regular, recurring and easily revocable state of organism which is characterized by relative immobility and significant increase in response threshold to environmental stimuli. Sleep disorders are common among haemodialysis patients.

AIM

The aim of this study was to investigate the effect of sleep hygiene education on sleep quality in haemodialysis patients.

MATERIALS AND METHODS

This study is a randomized controlled clinical trial. The participants of this study were 60 haemodialysis patients admitted to the Dialysis Center of Shahid Ayatollah Madani Hospital of Khoy, affiliated with the Urmia University of Medical Sciences. Sampling was done randomly and the partcipants were randomly divided into intervention group (30 patients) and control group (30 patients). Sleep quality of participants was measured before and after the intervention by Pittsburgh Sleep Quality Index (PSQI). Training process for sleep hygiene behaviours was presented to the participants face-to-face. The data were analysed using SPSS 16.

RESULTS

A significant difference in the mean (standard deviation) score for PSQI (p<0.001) was observed before and after intervention in the intervention group, while in the control group, the difference was not significant (p=0.704), In addition, a significant difference was observed in the mean (standard deviation) score for PSQI between the two, intervention and control groups after the educational intervention (p=0.034).

CONCLUSION

Sleep hygiene education, alongside other appro-aches, is a low-cost, accessible and practical method which can be implemented within a short period of time.

Re-designing Orem's Self-care Theory for Patients with Chronic Hepatitis

BACKGROUND

Hepatitis is an inflammatory disease which has many adverse effects on patients' life because of its chronic nature. Since Orem's theory of self-care is a grounded theory, the concepts and applications of this theory in patients with chronic hepatitis who have special needs may lead to some challenges. The purpose of this study was to explore self-care in patients with chronic hepatitis.

METHODS/DESIGN

A directed content analysis was used in this qualitative study. Participants were recruited from a metropolitan area. Data were collected through semi-structured interviews. The verbatim transcripts of the participants' interviews were analyzed according to directed content analysis.

RESULTS

In this study, four themes, suggested by Orem, were drawn from the data according to directed content analysis. The codes generated from the data were classified into concepts and then the concepts were assigned into these four themes. These themes were needs in the matrix of time and place, self-care agency, need for change in self-care and consequences of hepatitis.

CONCLUSION

The use of Orem's self-care theory cannot meet the need for self-care in hepatitis patients because these patients have vital sexual, respect and belonging, physical, economical, and psychological-behavioral needs, and lack adequate knowledge about self-care. Consequently, the specific self-care model developed in this study helps health professionals identify self-care activities in patients with chronic hepatitis.
