Patient-Reported Compliance in older age patients with chronic heart failure

Assessment of adherence to treatment recommendations among patients with heart failure: a cross-sectional study

BACKGROUND

Heart failure (HF) is a chronic condition characterized by significant impairment of the cardiovascular system, leading to a decline in health-related quality of life, recurrent hospitalizations, and increased mortality risk. It poses a substantial challenge for modern medicine, particularly when patients fail to adhere to therapeutic recommendations. The primary aim of this study was to evaluate the level of adherence to therapeutic guidelines among patients with HF and identify factors influencing adherence levels.

METHODS

The study comprised 105 HF patients admitted to the cardiology department. A diagnostic survey approach was utilized, employing the Adherence in Chronic Diseases Scale (ACDS) along with a self-developed questionnaire.

RESULTS

The findings revealed that 39.05% of participants exhibited a moderate level of adherence to therapeutic recommendations, while 34.29% reported high adherence and 26.67% displayed low adherence. Most of the patients (n = 66) had a rather good level of knowledge. Factors such as higher education (p < 0.001), engagement in mental work (p = 0.001), favorable socioeconomic status (p < 0.001), being in a stable relationship (p < 0.001), and residing with family (p < 0.001) were associated with increased adherence levels. The multivariable linear regression model indicated significant (p < 0.05) independent predictors that positively influenced the ACDS score, including being in a relationship, widowhood, and average or poor financial situation. Conversely, factors such as obesity and respiratory diseases were associated with a decrease in the ACDS score (p < 0.05).

CONCLUSIONS

This study underscores the moderate adherence level to therapeutic recommendations among HF patients. Sociodemographic factors including education level, relationship status, occupation, financial stability, and living arrangements significantly impact adherence. Conversely, patients with obesity, respiratory conditions, or frequent HF-related hospitalizations demonstrate lower adherence. Patient education emerges as a pivotal factor influencing adherence. Tailored interventions targeting these factors could enhance adherence and optimize HF management outcomes.

Loneliness, perceived social support, and their changes predict medical adherence over 12 months among patients with coronary heart disease

OBJECTIVES

This study investigated whether changes in loneliness and perceived social support predicted medical adherence in patients with coronary heart disease (CHD) over 12 months. Moreover, short-term and long-term buffering effects of social support on the association between loneliness and medical adherence were systematically examined.

DESIGN

A three-wave longitudinal study.

METHODS

Participants were 255 CHD patients with a mean age of 63 years. Medical adherence, loneliness, and perceived social support were assessed at baseline, 3 months, and 12 months. Hierarchical regression analyses were conducted to examine the influences of loneliness and social support as well as their changes on medical adherence over 12 months. Moderation analyses were performed to test buffering effects of baseline social support and its changes against loneliness and its changes, respectively.

RESULTS

Changes in loneliness significantly predicted medical adherence at 12 months (β = -.23, p = .001) but not at 3 months (β = -.10, p = .142). Changes in social support predicted medical adherence at both 3 (β = .23, p = .002) and 12 months (β = .26, p = .001). Social support concurrently buffered the adverse impact of loneliness on medical adherence (B = .29, SE = .12, p = .020) at baseline but did not at 3 or 12 months (Bs = -.21 to .40, SEs = .12 to .30, ps = .177 to .847).

CONCLUSIONS

Findings highlight the importance of monitoring loneliness and perceived social support continuously over time for CHD patients to promote medical adherence.

Medical and social factors influencing the utilization of healthcare services among older adults in Israel during the COVID-19 lockdown

Background

The corona virus disease 2019 (COVID-19) pandemic significantly impacted older adults. However, most older communities focused on the medical issues. The aims of this study were to identify the medical and social factors linked with the usage of medical services during the COVID-19 lockdown in Israel.

Methods

The study was conducted Over two periods of time from February to April in 2019 (P1), before the COVID-19 and from February to April in 2020 (P2), during the first lockdown. The study was conducted on people aged 65 and older in Israel. The variable statistics were analyzed using frequency tabulation, cross-tabulation frequencies, and t-tests. Two hierarchical logistic regressions were conducted over four steps for each period.

Results

The participants (n = 102,303) comprised 64.5% female (65,946) and 35.5% male (36,357) (mean age 80.5, SD- 7.46). It was found that participants who had not subscribed to the supportive community services were 7.47 times more likely to access medical services in P1 and 12.417 times more likely to access medical services during the lockdown. This variable was also found to be a strong predictor in the final model. The most significant variable for predicting the participants' needs during P2 was their previous needs in P1. Other social variables were living in assisted living home and living in community settlements. The presence of 12 diseases in this study did not predict service demand.

Conclusion

Community support reduces medical service demands during disasters and provides services for older adults. During pandemics, however, social services need to be expanded and made more easily accessible to older adults.

Evaluation of the pharmacotherapeutic impact on contractility recovery in patients with newly diagnosed, acute onset dilated cardiomyopathy

In patients with acute onset dilated cardiomyopathy (DCM) an improvement of left ventricular ejection fraction (LVEF) can occur as an effect of complex therapy. The aim of the study was to evaluate a pharmacotherapeutic impact on LVEF recovery in newly diagnosed DCM heart failure (HF) patients. A total of 2436 patients hospitalized due to acute decompensated HF were retrospectively analyzed. Finally, 24 patients with newly diagnosed DCM (51.4 ± 16.3 years, New York Heart Association 2.3 ± 0.7, LVEF 25 ± 10%) were observed (13.4 ± 16.0 months) in terms of the result of complex therapy. Patients were divided according to LVEF improvement on follow-up echocardiography: "recovery group" (LVEF improvement > 5%; n = 13) and "nonrecovery group" (∆LVEF ≤ 5%; n = 11). Evaluation of baseline parameters showed lower LVEF (19 ± 6 vs 31 ± 10%; P = .0048) and lower incidence of arterial hypertension (27% vs 73%; P = .043) in "recovery" group. After follow-up period LVEF was similar in both groups; however, significant LVEF improvement was demonstrated only in the "recovery group" (19 ± 6% to 34 ± 8%; P < .001). Only the "recovery group" showed significant HF symptoms reduction (New York Heart Association class: 2.5 ± 0.7 to 1.6 ± 0.6; P = .003). The "recovery group" had prescribed higher doses of loop diuretic (equivalent dose of furosemidum: 80 ± 38 mg vs 43 ± 24 mg; P = .025). Despite optimal therapy, significant LVEF improvement is observed only in the half of the patients with newly diagnosed DCM with HF with reduced EF. Prescription of higher doses of loop diuretics may have positive effect on the reduction of symptoms in newly diagnosed DCM HF patients. Lack of other risk factors such as arterial hypertension may increase the chance of LVEF recovery.

Experiences of Facilitators and Inhibitors to Treatment Adherence in Patients with Heart Failure

Treatment adherence is a fundamental aspect of heart failure (HF) management. This study aimed to explore the experiences of facilitators and inhibitors of treatment adherence in patients with HF. This descriptive qualitative study was conducted from May 2020 to June 2021. Participants including people with HF, their family caregivers and physicians, and nurses were selected purposefully, with the aim of obtaining sufficient information power. Semi-structured interviews were used to collect data. Data were analyzed using thematic analysis. Two main themes "the driving forces behind treatment adherence" and "the deterrent forces behind treatment adherence" emerged from the analysis. The first theme contained the following subthemes: "supportive family," "positive personality characteristics," and "having health literacy." The second theme consisted of "negligence," "psychological problems," "cultural, social, and economic problems," "physical limitations," and "lack of self-care management knowledge." Nurses can consider facilitators and inhibitors of treatment adherence in designing educational and care programs for patients with HF.

Socio-demographic characteristics and their relation to medical service consumption among elderly in Israel during the COVID-19 lockdown in 2020 as compared to the corresponding period in 2019

PURPOSE

The COVID-19 pandemic has led to the isolation of the population in Israel, including the elderly. The present study aimed to compare the consumption of medical services among adults over the age of 65 in Israel at the time of the first COVID-19 lockdown relative to the corresponding period the year before.

METHODS

We conducted a retrospective longitudinal observational quantitative research based on the Natali Healthcare Solutions Israel database of subscribers. Company subscribers over the age of 65 (N = 103,955) were included in the sample (64.5% women) in two time periods, before the COVID-19 outbreak-P1, in 2019, and during the first COVID-19 lockdown- P2 in 2020. Logistic regression was applied to examine service consumption for study variables.

RESULTS

The average number of referrals to services was lower during the COVID-19 lockdown period (M = 0.3658, SD = 0.781) compared to the corresponding period in the previous year (M = 0.5402, SD = 0.935). The average number of ambulance orders, doctor home visits and service refusals were higher when compared to the same period in the previous year. During both time periods, women (P1- M = 0.5631, SD = 0.951; P2- M = 0.3846, SD = 0.800) required significantly more (p < .000) services than men (P1- M = 0.5114, SD = 0.910; P2- M = 0.3417, SD = 0.753). Older, widowed people, living in non-Jewish/mixed localities, or in average or below average socioeconomic status localities required relatively more services to those with opposite socio-demographic traits (p < .000).

SUMMARY AND CONCLUSIONS

In a large sample of elderly in Israel, findings indicate a decrease in referrals to medical care during the first COVID-19 lockdown period, yet an increase in ambulance orders, doctor visits and service refusals. Socio-demographic characteristics showed a similar effect in both time periods. The period of the first COVID-19 lockdown was characterized by a higher incidence of medical service refusals as compared to the equivalent period in the previous year.

Flourishing despite Chronic Obstructive Pulmonary Disease (COPD): Findings from a Nationally Representative Survey of Canadians Aged 50 and Older

Chronic Obstructive Pulmonary Disease (COPD) is a leading cause of mortality and is often associated with serious disability and depression. Little is known about the characteristics of those who are in complete mental health (CMH) despite having COPD. This study’s objectives are to: (1) estimate the prevalence and odds of absence of psychiatric disorders (APD) and CMH among older adults that reported having COPD, compared to their peers that did not; (2) identify factors associated with APD and with CMH. Bivariate and logistic regression analyses were conducted using the nationally representative Canadian Community Health Survey—Mental Health. The results indicate that there was a significantly (p < 0.001) lower prevalence of APD (86.7% vs. 95.0%) and CMH (66.7% vs. 77.0%) among older adults aged 50+ with COPD (n = 703) compared to those without COPD (n = 10,189). Half of the sample was female (50.5%) and the majority of whom were under age 70 (62.5%). Factors significantly (p < 0.05) associated with higher odds of APD and of CMH among older adults with COPD include being married, having a confidant, being physically active, and having no lifetime history of major depressive disorder or generalized anxiety disorder. For every additional adverse childhood experience, the odds of APD declined by 31%. The majority of those with COPD are mentally flourishing despite having this disabling and life-threatening disorder. These findings underline the importance of targeted interventions and outreach to those most vulnerable to poorer mental health outcomes including the socially isolated.

Dynamic Trajectory of a Patient-Reported Outcome and Its Associated Factors for Patients with Chronic Heart Failure: A Growth Mixture Model Approach

PURPOSE

This study aimed to identify subgroups of chronic heart failure (CHF) patients with distinct trajectories of quality of life (QOL) and to identify baseline characteristics associated with the trajectories.

PATIENTS AND METHODS

Two-year, prospective, cohort study including 315 patients with CHF was conducted from July 2017. Information on QOL assessed by CHF-patient-reported outcomes measure (CHF-PROM) was collected at baseline, 6, 12, 18, and 24 months. Demographic and clinical variables were recorded at baseline. Growth mixture model was used to identify distinct trajectories of CHF-PROM and its physical, psychological, social, and therapeutic domains. Single factor analysis was employed to assess the factors associated with development of CHF-PROM over time.

RESULTS

Two classes of overall score of CHF-PROM were identified: poorer (14.0%) and better (86.0%). Poorer class tended to be aged, have low diastolic blood pressure, have concomitant atrial fibrillation, diabetes, chronic obstructive pulmonary disease, cancers, and central nervous system diseases, and used nitrates. Three classes of physical scores were identified: unstable-poorer (5.2%), stable-poorer (29.4%) and better (65.4%). Age, NYHA grade, chronic obstructive pulmonary disease, combined with cancers and central nervous system diseases were related to the grouping. Poorer (8.6%) and better (91.4%) classes of psychological scores were identified. Poorer class tended to be female and had concomitant atrial fibrillation. Degenerate class (34.6%) and meliorate class (65.4%) of therapeutic scores were identified. Degenerate class tended to have concomitant chronic obstructive pulmonary disease and use less angiotensin converting enzyme inhibitors.

CONCLUSION

We identified different classes with distinct trajectories of QOL that may help proper evaluate QOL and further improve its status for patients CHF.

Social Factors Contributing to Healthcare Service Requirements during the First COVID-19 Lockdown among Older Adults

This study examined social characteristics and their relations to healthcare service demand among older adults during the first COVID-19 lockdown in 2020. The sample was based on a cohort of 103,955 adults over the age of 65. A general index of needs was composed based on healthcare service use data and was predicted in a multi-nominal logistic regression. The frequency of the total needs significantly (p < 0.000) declined while supportive community services (4.9%, 2.0%), living in a community framework (27.0%, 15.2%), and living in a private residence (29.7%, 20.1%) were significantly associated (p < 0.000) with less frequent needs compared to the complementary groups. Supportive communities turned out to be an extremely important service for older adults. Policy makers should consider expanding supportive community services for older adults, as it was shown to have a positive correlation with lower healthcare service use, which might be an indicator of better overall health.

The morphometrical and topographical evaluation of the superior gluteal nerve in the prenatal period

Introduction

Advances in medical science are helping to break down the barriers to surgery. In the near future, neonatal or in utero operations will become the standard for the treatment of defects in the human motor system. In order to carry out such procedures properly, detailed knowledge of fetal anatomy is necessary. It must be presented in an attractive way not only for anatomists but also for potential clinicians who will use this knowledge in contact with young patients. This work responds to this demand and presents the anatomy of the superior gluteal nerve in human fetuses in an innovative way. The aim of this work is to determine the topography and morphometry of the superior gluteal nerve in the prenatal period. We chose the superior gluteal nerve as the object of our study because of its clinical significance—for the practice of planning and carrying out hip surgery and when performing intramuscular injections.

Material and methods

The study was carried out on 40 human fetuses (20 females and 20 males) aged from 15 to 29 weeks (total body length v-pl from 130 to 345 mm). Following methods were used: anthropological, preparatory, image acquisition with a digital camera, computer measurement system Scion for Windows 4.0.3.2 Alpha and Image J (accuracy up to 0.01 mm without damaging the unique fetal material) and statistical methods.

Results

The superior gluteal nerve innervates three physiologically significant muscles of the lower limb’s girdle: gluteus medius muscle, gluteus minimus muscle and tensor fasciae latae muscle. In this study the width of the main trunk of the nerve supplying each of these three muscles was measured and the position of the nerve after leaving the suprapiriform foramen was observed. A unique typology of the distribution of branches of the examined nerve has been created. The bushy and tree forms were distinguished. There was no correlation between the occurrence of tree and bushy forms with the body side (p > 0.05), but it was shown that the frequency of the occurrence of the bushy form in male fetuses is significantly higher than in female fetuses (p < 0.01). Proportional and symmetrical nerve growth dynamics were confirmed and no statistically significant sexual dimorphism was demonstrated (p > 0.05).

Conclusions

The anatomy of the superior gluteal nerve during prenatal period has been determined. We have identified two morphological forms of it. We have observed no differences between right and left superior gluteal nerve and no sexual dimorphism. The demonstrated high variability of terminal branches of the examined nerve indicates the risk of neurological complications in the case of too deep intramuscular injections and limits the range of potential surgical interventions in the gluteal region. The above research may be of practical importance, for example for hip surgery.

Pragmatic randomized trial assessing the impact of digital health technology on quality of life in patients with heart failure: Design, rationale and implementation

BACKGROUND

Self-care and patient engagement are important elements of heart failure (HF) care, endorsed in the guidelines. Digital health tools may improve quality of life (QOL) in HF patients by promoting care, knowledge, and engagement. This manuscript describes the rationale and challenges of the design and implementation of a pragmatic randomized controlled trial to evaluate the efficacy of three digital health technologies in improving QOL for patients with HF.

HYPOTHESIS

We hypothesize that digital health interventions will improve QOL of HF patients through the early detection of warning signs of disease exacerbation, the opportunity of self-tracking symptoms, and the education provided, which enhances patient empowerment.

METHODS

Using a fully electronic enrollment and consent platform, the trial will randomize 200 patients across HF clinics in the Yale New Haven Health system to receive either usual care or one of three digital technologies designed to promote self-management and provide critical data to clinicians. The primary outcome is the change in QOL as assessed by the Kansas City Cardiomyopathy Questionnaire at 3 months.

RESULTS

First enrollment occurred in September 2021. Recruitment was anticipated to last 6-8 months and participants were followed for 6 months after randomization. Our recruitment efforts have highlighted the large digital divide in our population of interest.

CONCLUSION

Assessing clinical outcomes, patient usability, and ease of clinical integration of digital technologies will be beneficial in determining the feasibility of the integration of such technologies into the healthcare system.

Adherence to self-care recommendations and associated factors among adult heart failure patients in public hospitals, Addis Ababa, Ethiopia, 2021: cross-sectional study

Background

Adherence to self-care recommendations in heart failure (HF) patients is essential to improve the patients’ quality of life, prevent hospital admission, and reduce mortality and morbidity. Nevertheless, poor adherence to self-care recommendations remains to be an extensive problem for HF patients. Thus, the aim was to assess adherence to self-care recommendations and associated factors among HF patients in public hospitals, Addis Ababa, Ethiopia, 2021.

Methods

An institutional-based cross-sectional study was conducted among adult HF patients from February 15 to April 15, 2021, in five public hospitals, in Addis Ababa, Ethiopia. A total of 294 adult HF patients completed an interviewer-administered questionnaire in the Amharic language. The Revised HF Compliance Questionnaire was used to measure the adherence to self-care recommendations of HF patients. Data was collected using the Revised HF Compliance Questionnaire, the Japanese heart failure knowledge scale, the multidimensional scale of perceived social support, and the chronic diseases self-efficacy scale. Study participants were selected through a systematic random sampling technique. Data were entered into Epi-info version 7.1 and then exported to SPSS Version 25 for analysis. Descriptive and logistic regression analyses were performed and the statistical significance of associations between the variables was determined using ORs with 95% CI and p-values < 0.05.

Results

Adherence to self-care recommendations among adult HF patients in public hospitals, in Addis Ababa, Ethiopia was 32.70%. Being female (AOR 4.66, 95% CI 1.58–13.67), patients who had high family monthly income (AOR 10.32, 95% CI 2.00–5.13), NYHA class III (AOR: 7.01, 95% CI 2.18–22.57) and class IV (AOR: 6.30, 95% CI 1.01–39.22), who had good self-efficacy (AOR 7.63, 95% CI 2.64–21.97), and who had good knowledge about HF (AOR 3.95, 95% CI 1.56–9.95) were more likely to have good adherence to self-care recommendations, p-value < 0.05.

Conclusion

This study revealed that 32.70% of adult HF patients had good adherence to self-care recommendations. Factors associated with adherence to self-care recommendations of adult HF patients are sex, family monthly income, NYHA classification, self-efficacy, and knowledge about HF. Therefore, interventions focused on sex, family monthly income, NYHA classification, self-efficacy, and knowledge about HF are required to improve adherence to self-care recommendations of adult HF patients.

Polish Nurses’ Knowledge of Heart Failure Self-Management Principles

Background: Only comprehensive care and structured education can have a significant impact on the effectiveness of treatment and prepare patients for self-care. Unfortunately, Polish nurses are not ready to perform comprehensive heart failure (HF) care tasks without careful preparation.The purpose of the study was to evaluate nurses’ knowledge of patient education in general and topic-specific perceptions of basic information important for HF self-care, and also to determine the variables (workplace, education, internship) that may affect the implementation of educational tasks in the care of patients with HF. Methods: The study involved 304 nurses who were surveyed using the Nurses’ Knowledge of Heart Failure Education Principles. Results: Cardiology nurses’ knowledge regarding patient education for self-care is insufficient. The overall knowledge score was the highest among nurses in provincial specialist hospitals and university hospitals and the lowest in regional hospitals in small towns (14.98 vs. 14.35 vs. 12.83 vs. 11.89, respectively). Nurses who completed a cardiological specialty demonstrated significantly more extensive knowledge than those who had completed other specialties (15.52 vs. 13.71). Conclusions: Cardiology nurses’ knowledge of HF self-care principles regarding patient education is satisfactory, but not with all mandatory issues, especially in the recognition of disease symptoms, exacerbations, and pharmacotherapy.

Effectiveness of a community-based integrated care ward (CICW) on 90-day readmission among the elderly people: a retrospective cohort study of a rural area in Japan

Objective: Community-based integrated care wards (CICW) play a role in supporting the return of patients to their homes. However, studies investigating the readmission risk associated with CICW are lacking. To investigate the influence of CICW on readmission, we conducted a retrospective cohort study among Japanese elderly people.

Materials and Methods: This study used data from the Diagnosis Procedure Combination (DPC) and medical records of the Hamada Medical Center, Shimane Prefecture in 2014–2019. The number of subjects and readmission in each hospitalization case (general ward only [GW] and CICW) were 1,521 and 416 subjects and 152 and 49 cases, respectively. We selected the hospitalization cases for heart failure (I30–I52), ischemic heart disease (I20–I25), pneumonia (J09–J18), chronic lower respiratory tract diseases (J40–J47), intestinal diseases (K55–K64), cerebrovascular disease (I60–I69), gallbladder, bile duct, and pancreatic diseases (K80–K87) from the International Statistical Classification of Diseases and Related Health Problems (ICD-10). The hazard ratios (HRs) and 95% confidence intervals (CIs) for readmission via a CICW were estimated using a multivariate Cox proportional hazards model.

Results: The HRs for readmission associated with CICW were not different between the shorter and longer durations, considering the percentage of CICW stay. Compared with GW cases, the HR of CICW cases was 0.40 (95% CI, 0.17–0.92) in coordination with outside agencies of hospital discharge support. While the HR of GW cases was 2.35 (95% CI 1.01–5.47), a significantly increased risk was observed in people living alone. A similar risk was not observed in CICW cases with the HR of 0.56 (95% CI 0.15–2.07).

Conclusion: The present study observed decreased risk of readmission among the patients discharged from CICW, compared to GW. Further research is required to clarify the causal factors for this decreased risk.

Short-term effect of multi-pollutant air quality indexes and PM2.5 on cardiovascular hospitalization in Hamadan, Iran: a time-series analysis

Air pollutants are the most important environmental factors that contributed to cardiovascular disease (CVD). The present study aimed to investigate the number of hospitalization due to heart failure (HF) and myocardial infarction (MI) following the air pollutant exposure using a time-series regression analysis with a distributed lag model in Hamadan, Iran (2015-2019). A total of 2091 cases of CVD were registered. Based on the findings, the highest health effects on HF hospitalization were observed with air quality health index (AQHI) at lag 9 (RR = 1.043, 95% CI 0.991-1.098), and air quality index (AQI) at lags 2, 7, and 9 (RR = 1.001, 95% CI 0.998-1.002), for an increase in 1 unit of the indexes, and with PM_2.5 at lag 0 (RR = 1.001, 95% CI 0.996-1.004) for 10 μg/m³ increase in PM_2.5 levels. The highest health effects on MI hospitalization were calculated with AQHI at lag 10 (RR = 1.059, 95% CI 1.001-1.121) and AQI at lags 1 and 2 (RR = 1.001, 95% CI 0.998-1.002), for an increase in 1 unit of the indexes, and with PM_2.5 at lag 8 (RR = 1.002, 95% CI 0.997-1.005) for 10 μg/m³ increase in PM_2.5 levels. According to a seasonal classification, results showed that hospitalization in the warm season was higher than that of the cold season. Based on our knowledge, the current study is the first study that investigated the effect of air quality indexes on hospitalization due to HF and MI in Iran. Findings can provide basic information to plan preventive measures for reducing exposure chance and hospitalization rate in high-risk people.

Compliance with Telemonitoring in Heart Failure. Are Study Findings Representative of Reality?: A Narrative Literature Review

Introduction: Telemonitoring technologies enable medical teams to remotely manage outpatients with heart failure (HF) and reduce their risk of HF-related hospitalizations. However, noncompliance threatens the effectiveness of these approaches. This review aims to identify whether patients who are less likely or unable to comply with telemonitoring and their instructions for use are represented by interventional telemonitoring studies, and if their exclusion from studies is resulting in study findings not representative of clinical reality. Methods: A narrative literature review was conducted to identify interventional telemonitoring studies reporting compliance rates for HF patients. A search of PubMed and Medline databases identified eligible studies published between January 2000 and June 2021. Results: Twenty-five (n = 25) eligible studies with an interventional study design were identified. Reported compliance with telemonitoring ranged between 37% and 98.5%; however, 72% of studies reported good or medium compliance. A majority (76%) of studies had exclusion/inclusion criteria favoring the enrollment of patients who may be more likely to comply with telemonitoring and their instructions for use. Forty percent of studies had a sample with a mean or median age of <65 years. Participants were more likely to be male (majority in 92% of studies) and white (majority in 78% of studies that reported ethnicity). Conclusion: Compliance rates reported by current studies are unlikely to be generalizable to the wider HF population, particularly patients who are less likely or unable to comply with telemonitoring. Studies are therefore likely overestimating compliance rates. Future innovation should focus on designing "low compliance" solutions that require minimal engagement from users and future studies should aim to recruit a more generalizable cohort of patients. To achieve a more standardized metric of compliance, studies should report compliance (however defined) achieved by the 25th, 50th, and 75th percentile of all patients enrolled.

Impact of Beliefs about Medicines on the Level of Intentional Non-Adherence to the Recommendations of Elderly Patients with Hypertension

Background: Non-adherence to pharmaceutical treatment is one of the most common causes of uncontrolled hypertension. Non-adherence may be intentional or unintentional. In the case of intentional non-adherence, it is crucial to understand the reasons behind it. The literature increasingly addresses the issue of beliefs and concerns about medication, but studies on this subject performed in a Polish population of hypertensive patients are still lacking. The aim of the study was to assess the level of intentional non-adherence among patients with hypertension, and to determine the relationship between beliefs about medication and the level of intentional non-adherence to treatment in elderly patients with hypertension. Material and methods: The study included 300 patients (106 of whom were male, mean age (SD) 71.71 (8.12) years) with hypertension, treated at a hypertension clinic. The following instruments were used: the Intentional Non-Adherence Scale (INAS) for evaluating intentional non-adherence, and the Beliefs about Medicines Questionnaire (BMQ) for evaluating patients’ beliefs and opinions regarding medication. Socio-demographic and clinical data were obtained from patients’ medical records. Results: The mean (SD) INAS score in the study was 47.28 (19.12). Patients were most concerned about the harm caused by medication, and least concerned about the necessity to take medication (mean score per item 3.49 vs. 2.14). Correlation analysis demonstrated weak correlations between BMQ and INAS: higher scores for necessity were associated with more intentional non-adherence (r = 0.174, p = 0.003), while higher scores for overuse, harm, and concerns were associated with less intentional non-adherence (respectively: r = −0.253, p < 0.001 vs. r = −0.336, p < 0.001 vs. r = −0.351, p < 0.001). In multiple-factor analysis, factors increasing the level of intentional non-adherence were elderly age (β = −0.352, p = 0.009), multimorbidity (β = −2.374, p = 0.035), and a higher BMQ concerns score (β = −1.376, p < 0.001), while being single was an independent predictor decreasing intentional non-adherence (β = 5.646, p = 0.013). Conclusions: The overall level of intentional non-adherence among patients with hypertension is moderate, but approximately one third of patients with hypertension demonstrate a high level of non-adherence. Independent determinants of intentional non-adherence include concerns, elderly age, multimorbidity, and being single.

Sex Differences in the Association between Atrial Fibrillation and 90-Day Adverse Outcomes among Older Adults with Heart Failure: A Retrospective Cohort Study

Sex differences in the prognostic impact of coexisting atrial fibrillation (AF) in older patients with heart failure (HF) have not been well-studied. This study, therefore, compared sex differences in the association between AF and its 90-day adverse outcomes (hospital readmissions and emergency room (ER) visits) among older adults with HF. Of the 250 older adult patients, the prevalence rates of coexisting AF between male and female HF patients were 46.0% and 31.0%, respectively. In both male and female older patients, patients with AF have a significantly higher readmission rate (male 46.0%, and female 34.3%) than those without AF (male 6.8%, and female 12.8%). However, there are no significant differences in the association between AF and ER visits in both male and female older HF patients. The multivariate logistic analysis showed that coexisting AF significantly increased the risk of 90-day hospital readmission in both male and female older patients. In addition, older age in males and longer periods of time after an HF diagnosis in females were associated with an increased risk of hospital readmission. Consequently, prospective cohort studies are needed to identify the impact of coexisting AF on short- and long-term outcomes in older adult HF patients by sex.

The roles of health literacy and social support in improving adherence to self-care behaviours among older adults with heart failure

Aim

To describe the associations between health literacy, social support and self‐care behaviours in older adults with heart failure.

Design

A cross‐sectional descriptive study.

Methods

A total of 252 older adults were recruited from a tertiary care hospital from September 2018–February 2019. Structured questionnaires and medical record reviews were used for data collection. Two steps of hierarchical regression analysis were employed to determine the predictors of self‐care behaviours.

Results

Health literacy (β = 0.27, p < .001) and social support (β = 0.32, p < .001) were significant determinants of self‐care behaviours in older adults with heart failure. Together, they explained 22% of the variance in self‐care behaviours.

Conclusion

Health literacy and perceived social support were positively associated with self‐care behaviours among older heart failure patients. Our findings can help health professionals develop heart failure self‐care interventions to enhance health literacy skills and social support for older adults.
