Social support and adherence to treatment in hypertensive patients: a meta-analysis

The Influence of Marital Status on the Survival of Patients with Uveal Melanoma

Background

Uveal melanoma (UM) is the most common primary intraocular tumor in adults and arises from the uvea. Marital status was a vital factor among physical conditions and social networks of cancer patients. Our study aimed to evaluate the impact of marital status on the outcomes among patients with UM.

Methods

Patients with UM newly diagnosed from 2004 to 2015 were extracted, and the data were extracted from Surveillance, Epidemiology, and End Results (SEER) program. Overall survival (OS) was measured via the log-rank test, as well as cancer-specific survival (CSS) was also calculated via the same method. Cox proportional hazards models were applied to assess whether marital status was related to both OS and CSS. Furthermore, we performed subgroup analysis depending on different sexes and SEER stages.

Results

In total, 4217 eligible patients were involved. Of these patients, 66.2% (n = 2793) were married, 14.6% (n = 615) were single, and 9.0% (n = 379) were divorced or separated, as well as widowed were 10.2% (n = 430). The 5-year OS of married, single, divorced or separated, and widowed patients was 74.0%, 72.8%, 68.6%, and 55.8%, respectively. The results indicating better OS and CSS occurred among married patients. Other factors such as sex, age at diagnosis, and SEER stage were also correlated with survival in UM patients. Furthermore, subgroup analyses were consistent with the results above.

Conclusion

Marital status was proved to be an independent prognostic value for survival in UM patients. In addition, contrast to married patients, widowed individuals showed poor OS and CSS at different subgroup analyses.

Social Network and Risk of Poor Sleep Outcomes in Older Adults: Results from a Spanish Prospective Cohort Study

BACKGROUND

Not having social support has been associated with poor sleep, but most prospective studies were based on social support in the workplace, did not account for baseline sleep characteristics or did not assess sleep duration. Moreover, no previous research has evaluated the relationship between social network and sleep outcomes in an older Spanish population.

METHODS

1444 individuals aged ≥60 years were followed between 2012 and 2015. At baseline (2012), a poor social network index (SNI) was computed by summing the following dichotomous indicators: not being married; living alone; not having daily contact with family, friends or neighbors; being alone ≥8h/day; lacking someone to go for a walk with; not having emotional support; lacking instrumental support. Higher values in SNI indicate less social support. In 2012 and 2015, information was collected on sleep duration (hours/day) and on symptoms of sleep disturbance: bad overall sleep; difficulty falling asleep, awakening during nighttime, early awakening with difficulty getting back to sleep, use of sleeping pills, feeling restless in the morning, being asleep at daytime, and having an Epworth Sleepiness Scale>10. Poor sleep duration was defined as short (<6 h) or long (>9 h) nighttime sleep, and poor sleep quality as having ≥4 indicators of sleep disturbance. Linear or logistic regression models were used to assess the relationship of SNI with changes in sleep duration and in number of sleep disturbance indicators, or with the risk of developing poor nighttime sleep or poor sleep quality.

RESULTS

Compared to individuals in the lowest (best) quartile of the SNI in 2012, those in the second, third and fourth quartiles, respectively, displayed a mean (95%confidence interval [95% CI]) change of 2.32 (-7.58-12.22), -2.70 (-13.19-7.79) and -13.04 (-23.41- -2.67) minutes in sleep duration from 2012 to 2015; p for trend=0.02. A 1-point increase in the SNI at baseline was associated with an increased risk of short nighttime sleep (Odds Ratio [OR] and 95% CI: 1.22 (1.05-1.42)), poor sleep quality (OR: 1.13; 95% CI: 1.00-1.30), and of the indicator of sleep disturbance "early awakening with difficulty getting back to sleep" (OR: 1.20; 95% CI: 1.07-1.35).

CONCLUSION

A poorer social network is associated with a higher risk of short sleep and poor sleep quality in older adults.

Effectiveness of interventions for optimising adherence to treatments for the prevention and management of scars: A systematic review

OBJECTIVES

To identify the adherence interventions used with people receiving treatments to prevent or manage scarring, the effectiveness of these interventions, and the theoretical frameworks on which these interventions were based.

DATA SOURCES

Databases (PubMed, Embase, Web of Science, CINAHL, PsychINFO and OTseeker) were searched (09.10.2020) with no date or language restrictions. Grey literature databases, clinical trial registries and references lists of key papers were also searched.

REVIEW METHODS

Eligible randomised controlled trials included people using treatments for scarring following skin wounds, interventions that may improve adherence, and outcomes measuring adherence. Risk of bias (selection, performance, detection, attrition, reporting) and certainty of evidence (inconsistency, imprecision, indirectness, publication bias) were assessed.

RESULTS

Four randomised trials were included with 224 participants (17 children) with burn scars. Interventions involved educational (three trials) or technology-based components (four trials) and ranged in length from two weeks to six months. All four trials reported greater adherence rates in the intervention group compared with standard practice [standardised mean difference = 1.50 (95% confidence interval (CI) = 0.91-2.08); 2.01 (95% CI 1.05-2.98); odds ratio = 0.28 (95% CI = 0.11-0.69)]. One trial did not report original data. The certainty of evidence was very low.

CONCLUSION

Adherence interventions using education or technology for people receiving burn scar treatment may improve adherence. Further studies are needed particularly in children, with a focus on including outcomes of importance to patients (e.g. quality of life) and identifying core components of effective adherence interventions using theoretical frameworks.

The effect of loneliness and perceived social support on medication adherence self-efficacy in hypertensive patients: An example of Turkey

This study was conducted to investigate the effect of loneliness and perceived social support on medication adherence self-efficacy in hypertensive patients. This descriptive cross-sectional study was conducted between March and June 2015 at 5 Family Health Centers in central Erzincan in eastern Turkey. The data were collected through face-to-face interviews using a descriptive questionnaire, the UCLA Loneliness Scale, the Multidimensional Scale of Perceived Social Support, and the Medication Adherence Self-Efficacy Scale Short Form. The mean score obtained from the UCLA Loneliness Scale was 38.35 ± 9.85, from the Multidimensional Scale of Perceived Social Support 64.10 ± 18.31, and from the Medication Adherence Self-Efficacy Scale 40.27 ± 11.97. The mean UCLA Loneliness Scale score was found to have a low negative correlation with the mean Medication Adherence Self-Efficacy Scale score and a highly significant negative correlation with the mean Multidimensional Scale of Perceived Social Support score (P < .001). There was also a very low positive significant correlation between the mean scores of the Multidimensional Scale of Perceived Social Support and the Medication Adherence Self-Efficacy Scale (P < .001). This study revealed that individuals with hypertension perceived a moderate level of loneliness, and their perceived social support and medication adherence self-efficacy were higher than the moderate level. Perceived loneliness and perceived social support were significant indicators of perceived medication adherence self-efficacy. Therefore, effective consultancy services should be provided to hypertensive patients to increase their social support and to make positive changes in their perceived loneliness so that their perceived medication adherence self-efficacy can be improved.

Diabetes Mellitus Versus Hypertension-Does Disease Affect Pharmacological Adherence?

The aim of the study was to answer the questions whether a chronic disease can have a significant impact on the level of adherence and whether there are differences in adherence-related predictors depending on the chronic disease. The study included 1,571 patients (mean age 64.7 ± 11.3) with chronic diseases [1,030 diabetes mellitus (DM) type 2 and 541 hypertension (HA)]. Adherence was assessed using the Adherence Refills Medication Scale (ARMS). The average adherence score for the whole group was 18.9. Fifty-five percent of patients had a low level of adherence. A comparison between DM and HA shows a statistically significant difference and a higher level of adherence with pharmacological recommendations in the group of patients with type 2 DM (17.5 ± 12.0 vs 19.2 ± 8.0). In the single factors analysis, HA diagnosis had a statistically significant negative effect on adherence (β=0.92, p ≤ 0.001). In simple linear regression analysis, independent of chronic disease, a higher level of adherence was observed among women (β=-0.40, p=0.015), people with secondary education (β=-1.26, p ≤ 0.001), and inactive patients (β=-0.48; p=0.005). However, place of residence - countryside (β =0.35, p=0.044) and higher education (β=0.90, p ≤ 0.001) had a negative influence on the level of adherence. In multiple linear regression analysis HA (B=0.99; p ≤ 0.001), female gender (B=-0.47; p=0.003) and secondary education (B=-1.16; p ≤ 0.001) were important independent determinants of adherence. (1) Hypertension is an independent, statistically significant predictor that reduces the adherence level. (2) Female gender and higher education are the most important determinants improving adherence to pharmacological therapy. (3) There is a different pattern of predictors of adherence among patients: occupational activity plays an important role in DM, while education plays a role in HA.

Social support, social context and nonadherence to treatment in young senior patients with multimorbidity and polypharmacy followed-up in primary care. MULTIPAP Study

OBJECTIVE

To estimate the prevalence of nonadherence to treatment and its relationship with social support and social context in patients with multimorbidity and polypharmacy followed-up in primary care.

METHODS

This was an observational, descriptive, cross-sectional, multicenter study with an analytical approach. A total of 593 patients between 65-74 years of age with multimorbidity (≥3 diseases) and polypharmacy (≥5 drugs) during the last three months and agreed to participate in the MULTIPAP Study. The main variable was adherence (Morisky-Green). The predictors were social support (structural support and functional support (DUFSS)); sociodemographic variables; indicators of urban objective vulnerability; health-related quality of life (EQ-5D-5L-VAS & QALY); and clinical variables. Descriptive, bivariate and multivariate analyses with logistic regression models and robust estimators were performed.

RESULTS

Four out of ten patients were nonadherent, 47% had not completed primary education, 28.7% had an income ≤1050 €/month, 35% reported four or more IUVs, and the average perceived health-related quality of life (HRQOL) EQ-5D-5L-VAS was 65.5. The items that measure functional support, with significantly different means between nonadherent and adherent patients were receiving love and affection (-0.23; 95%CI: -0.40;-0.06), help when ill (-0.25; 95%CI: -0.42;-0.08), useful advice (-0.20; 95%CI: -0.37;-0.02), social invitations (-0.22; 95%CI:-0.44;-0.01), and recognition (-0.29; 95%CI:-0.50;-0.08). Factors associated with nonadherence were belonging to the medium vs. low tertile of functional support (0.62; 95%CI: 0.42;0.94), reporting less than four IUVs (0.69; 95%CI: 0.46;1.02) and higher HRQOL perception (0.98; 95%CI: 0.98;0.99).

CONCLUSIONS

Among patients 65-74 years of age with multimorbidity and polypharmacy, lower functional support was related to nonadherence to treatment. The nonadherence decreased in those patients with higher functional support, lower urban vulnerability and higher perceived health status according to the visual analog scale of health-related quality of life.

Examining and adapting the information-motivation-behavioural skills model of medication adherence among community-dwelling older patients with multimorbidity: protocol for a cross-sectional study

INTRODUCTION

Multimorbidity is highly prevalent among older patients and has been shown to be associated with poor health outcomes and lower quality of life. Adherence to medication treatments is essential in order to maximise the efficacy of treatments and improve health outcomes. However, nearly half of the older patients with multimorbidity fail to adhere to their medications, which can result in an increased risk of adverse health events, lower quality of life and higher healthcare cost. Only a few studies have explored the underlying mechanism and influencing factors of medication adherence among older patients with multimorbidity, which are inadequate to provide robust evidence for the development and evaluation of the medication adherence interventions. This study aims to examine and adapt the information-motivation-behavioural skills (IMB) model, a widely used social behaviour theory, to explain the medication adherence behaviour among community-dwelling older patients with multimorbidity.

METHODS AND ANALYSIS

A cross-sectional study will be conducted in community settings in China. Around 309 older patients with multimorbidity will be recruited to complete questionnaires on adherence knowledge, adherence motivation, adherence self-efficacy, medication adherence, medication treatment satisfaction, depressive symptoms, treatment burden, disease burden and basic demographic information. Structural equation modelling will be used to analyse and validate the relationships among variables in the IMB model.

ETHICS AND DISSEMINATION

This study has been approved by the Survey and Behavioral Research Ethics Committee of the Chinese University of Hong Kong (reference number SBRE-18-675). The study results will be published in peer-reviewed journals and presented in academic conferences and workshops.

Determining the Prevalence of and the Factors Associated with Antihypertensive Medication Non-Adherence in the Gaza Strip

Background

This study aimed to estimate the prevalence of and determine the factors associated with antihypertensive medication (A-HTNM) non-adherence among hypertension care seekers attending primary health clinics in the Gaza Strip.

Methods

A cross-sectional survey was conducted as the recruitment phase of a clustered randomized controlled trial including 538 participants. The participants were randomly selected from 10 primary health care centers by two-stage cluster random sampling. A structured questionnaire was used to collect data through face-to-face interview. The questionnaire was developed based on the World Health Organization determinants for medication non-adherence and the Health Belief Model. The main outcomes of this study were the prevalences of A-HTNM non-adherence and its associated factors. Adherence status was assessed using the eight-item Morisky Self-Report Medication Adherence Scale. Data were analyzed by STATA ver. 14.0 (Stata Corp., College Station, TX, USA) using a standard complex survey, accounting for unresponsiveness and the clustering sampling approach.

Results

The overall prevalence of A-HTNM non-adherence was 65.8% (95% confidence interval [CI], 59.2–71.8). Among all studied predictors, only self-efficacy of participants (odds ratio [OR], 3.8; 95% CI, 1.79–2.84) and social support (OR, 2.26; 95% CI, 2.82–5.11) remained significantly associated with A-HTNM non-adherence after adjusting for age, education level, number and frequency of A-HTNM doses per day, and comorbidities.

Conclusion

The high prevalence of non-adherence highlights the need for serious intervention to enhance the adherence rate among hypertension patients. The associated factors can be considered when developing appropriate interventions.

Development and content validation of the Multifactoral assessment of perceived social support (MAPSS), a brief, patient-reported measure of social support for use in HIV care

Low perceived social support (SS) negatively impacts health outcomes. We developed a measure of perceived SS for use in HIV care. We sought and categorized legacy items, selecting strongest items within categories. We elicited SS concepts from patients in English/Spanish, coded transcripts to match item pool content, and developed new items for salient unrepresented content. In focus groups, patients prioritized highly-matched items. We conducted cognitive interviews on high-priority items, and validity testing on final items against two legacy measures. From interviews (n = 32), we matched the following concepts: sense of belonging/inclusion; communication; emotional support; feeling accepted by others as a person; companionship; and practical support. We identified a new concept: support from friends/family in remaining healthy. Focus groups (n = 23) prioritized emotional support, communication, and support to remain healthy. Cognitive interviews (n = 30) found items were well-understood. The final 8-item measure performed well with patients (n = 708), with good construct validity. We used an Item Response Theory program to create a 3-item Short Form version of the measure, which captures 96% of patients indicating low social support. We developed the Multifactoral Assessment of Perceived Social Support (MAPSS) and Short Form (MAPSS-SF); brief, clinically relevant, sufficiently unidimensional measures of SS for use in HIV care.

Exploring the use of assistive products to promote functional independence in self-care activities in the bathroom

In homes, problems in daily functioning of older people often occur in the bathroom, especially in the transfers to the toilet and/or shower/bath. Assistive products have the potential to maximise functional independence (i.e. performance without assistance from another person) in everyday activities; however, more research is needed to better understand the impact of this technology on independence in the transfers in the bathroom. Additionally, little is known about the role of the environmental factors in the process of implementing bathroom adaptations. Therefore, this cross-sectional study aimed to examine the relationship between the use of assistive products and independence in the transfers in the bathroom. The secondary objective was to determine the role of the environmental factors in predicting the implementation of bathroom adaptations. 193 community-dwelling older adults with disabilities in the basic activities of daily life, who requested public long-term care services in Spain, were included. Data was collected in the participant´s homes using a standardised assessment procedure. There was no significant association between the number of categories of assistive products used in the toilet transfer and the independent performance of this task. In a multivariate model, the number of categories of assistive products used in the transfer to shower/bath was positively associated with the independent performance of this transfer (OR = 2.59, 95%CI = 1.48–4.53; p = 0.001). A multivariate analysis revealed that social functioning was significantly associated with the implementation of a bathroom adaptation; social risk was lower in participants who made an adaptation (OR = 0.76, 95%CI = 0.63–0.93; p = 0.006). Assistive products may play an important role in promoting independence in the bathroom. Assistive product needs should be addressed when planning community-based interventions aimed at improving daily life. Moreover, social functioning had a strong influence on the installation of bathroom adaptations, suggesting the importance of paying special attention to social factors in the home adaptations planning process.

What determines immigrant caregivers' adherence to health recommendations from child primary care services? A grounded theory approach

AIM

To investigate the diversity and specificity of the determinants of immigrant caregivers' adherence to child primary care (CPC) health recommendations.

BACKGROUND

Immigrant caregiver's adherence to CPC health recommendations is of utmost importance to minimize their children's health-related vulnerabilities. Some research has been conducted on the determinants of immigrants' access to health services, but much less is known about the determinants of their adherence to health professionals' recommendations once they get there, especially in a primary health care context. This study contributes to bridge these gaps.

METHODS

Interviews and focus groups were conducted, with immigrant and non-immigrant caregivers living in Portugal (n=35), from heterogeneous socioeconomic backgrounds. Focus group and individual interview scripts were developed to explore caregivers' understanding and use of CPC services and, particularly, their adherence to CPC recommendations. A socio-demographic questionnaire was also administered. Qualitative data were analyzed using a grounded theory methodology.

FINDINGS

'Adherence to CPC health recommendations' is a core and multidimensional concept. Several determinants were identified at individual, interpersonal, organizational and structural levels. Some determinants were highlighted both by immigrant and non-immigrant caregivers: valuing children's health, usefulness of recommendations, perceived health-care professionals' competence, central role of vaccination in CPC and caregivers' socio-economic conditions. Other determinants were specifically mentioned by immigrant caregivers: expectations about traditional versus pharmacological treatments, cultural mismatches in children's care practices, perceived quality of Portuguese CPC services versus CPC from countries of origin. These results provide innovative theoretical and empirical contributions to the field of primary health care and, particularly, to immigrant caregivers' adherence behaviors. Implications for research on treatment adherence in primary care contexts, the development of interventions that promote caregivers' adherence to CPC health recommendations and for child protection will be discussed.

Adherence to cardiovascular medication: a review of systematic reviews

BACKGROUND

Use of cardiovascular medication has increased over time, especially for primary and secondary prevention, with polypharmacy common.

METHODS

Review of published systematic reviews of the factors and outcomes associated with adherence to cardiovascular medication using MEDLINE, Embase, CINAHL and PsycINFO databases. Quality was assessed using the AMSTAR tool.

RESULTS

Of 789 systematic reviews identified, 45 met the inclusion criteria and passed the quality assessment; 34 focused on factors associated with adherence, and 11 on outcomes. High heterogeneity, both between and within reviews, precluded meta-analysis and so a pooled estimate of adherence levels could not be derived. Adherence was associated with disease factors, therapy factors, healthcare factors, patient factors and social factors, though with some inconsistencies. In total, 91% of reviews addressing outcomes reported that low adherence was associated with poorer clinical and economic endpoints.

CONCLUSIONS

Factors from across five key domains relate to non-adherence to cardiovascular medications, and may contribute to poorer clinical outcomes. Interventions to improve adherence should be developed to address modifiable factors and targeted at those at highest risk of non-adherence. Adherence research is highly heterogeneous to-date and efforts to standardize this should be implemented to improve comparability.

Marital status and survival in patients with soft tissue sarcoma: A population-based, propensity-matched study

Background

Marital status serves as an independent prognostic factor for survival in a variety of cancers. However, its prognostic impact on soft tissue sarcoma (STS) has not yet been established.

Objective

To investigate the impact of marital status on survival outcomes among STS patients.

Methods

A total of 18 013 STS patients diagnosed between 2004 and 2015 were extracted from Surveillance, Epidemiology, and End Results (SEER) database. The marital status was classified into married, divorced, widowed, and single. Kaplan‐Meier analysis and multivariate Cox proportional hazards regression analysis were conducted to establish the impact of marital status on the overall survival (OS) and cancer‐specific survival (CSS). Subgroup analyses were conducted based on age, SEER historic stage and surgery condition. Propensity score matching (PSM) was used to perform a 1:1 matched‐pair analysis to minimize the group differences caused by covariates.

Results

Married patients enjoyed better 5‐year overall survival (OS) and 5‐year cancer‐specific survival (CSS), compared with patients who were divorced, widowed, and single, respectively. Multivariate Cox proportional hazards regression analysis revealed that marital status was an independent prognostic and protective factor for survival among STS patients, and unmarried status was associated with higher mortality hazards for both OS and CSS. Additionally, widowed individuals had the highest risks of overall and cancer‐specific mortality compared to other unmarried groups. In the subgroup analyses, similar associations were also found. Furthermore, marital status still remained an independent prognostic and protective factor for both OS and CSS even in 1:1 matched‐pair analysis.

Conclusions

Marital status was an independent prognostic and protective factor for survival for STS patients. Widowed patients suffered the highest death risks among the unmarried groups.

The social determinants of chronic disease management: perspectives of elderly patients with hypertension from low socio-economic background in Singapore

Background

In Singapore, the burden of hypertension disproportionately falls on the elderly population of low socio-economic status. Despite availability of effective treatment, studies have shown high prevalence of sub-optimal blood pressure control in this group. Poor hypertension management can be attributed to a number of personal factors including awareness, management skills and overall adherence to treatment. However, these factors are also closely linked to a broader range of community and policy factors. This paper explores the perceived social and physical environments of low socio-economic status and elderly patients with hypertension; and how the interplay of factors within these environments influences their ability to mobilise resources for hypertension management.

Methods

In-depth interviews were conducted in English, Chinese, Chinese dialects and Malay with 20 hypertensive patients of various ethnic backgrounds. Purposive sampling was adopted for recruitment of participants from a previous community health screening campaign. Interviews were translated into English and transcribed verbatim. We deductively analysed leveraging on the Social Model of Health to identify key themes, while inductive analysis was used simultaneously to allow sub-themes to emerge.

Results and discussion

Our finding shows that financing is an overarching topic embedded in most themes. Despite the availability of multiple safety nets, some patients were left out and lacked capital to navigate systems effectively, which resulted in delayed treatment or debt. The built environment played a significant role in enabling patients to access care easily and lead a more active lifestyle. A closer look is needed to enhance the capacity of patients with mobility challenges to enjoy equitable access. Furthermore, the establishment of community based elderly centres has enabled patients to engage in meaningful and healthy social activities. In contrast, participants’ descriptions showed that their communication with healthcare professionals remained brief, and that personalised and meaningful interactions that are context and culturally specific are essential to advocate for patients’ overall treatment adherence and lifestyle modification.

Conclusion

Elderly patients with hypertension from lower socio-economic background have various unmet needs in managing their hypertension and other comorbidities. These needs are closely related to broader societal factors such as socio-demographic characteristics, support systems, urban planning and public policies, and health systems factors. Policy decisions to address these needs require an integrated multi-sectoral approach grounded in the principles of health equity.

Potential use of a "Blood Pressure Action Sheet" for Indonesian patients with hypertension living in rural villages: a qualitative study

Purpose

The aim of the study was to obtain feedback on the layout, content, and potential use of a blood pressure (BP) action sheet, a purpose-designed written resource for Indonesian patients with hypertension.

Methods

Telephone interviews were conducted with 13 health professionals, 12 community health workers, and 12 patients in rural Yogyakarta, Indonesia, to explore their impressions of the BP action sheet, how the sheet might affect management of hypertension, and suggestions for improvement.

Results

Participants felt that the sheet presented useful information about achieving the target BP and managing hypertension. The use of the sheet could be optimized by engaging community health workers to help explain the information and to provide assistance around the stated actions for hypertension management. A more attractive design and inclusion of more details were suggested. Both patients and health care workers expressed interest in using the sheet.

Conclusion

The BP action sheet has potential as a useful resource for patients with hypertension by providing information, recording target BP, and facilitating patient-centered communication. Use of the BP action sheet might provide an effective low-cost way for health professionals and community health workers to encourage patients to achieve their target BP.

Effect of social support on the treatment adherence of hypertension patients

This descriptive study was conducted to determine the effect of social support on drug treatment adherence in patients with hypertension. The sample of this study consisted of 259 patients who met the research criteria, agreed to participate in the research, and admitted to the cardiology clinic of a university hospital in Turkey between January and June 2017. Data were collected by "Patient Information Form", "Adherence to Drug Treatment Self-Efficacy Scale", and "Multidimensional Perceived Social Support Scale". It was determined that 48.3% of the patients participating in the study were in the 61-75 age group, 58.7% were female, 91.9% were married, and 66.4% were living in the city. It was also found that 71% of the patients had at least one relative or person with hypertension in the family, 79.2% were using at least one blood pressure medication, 61% adhered to his/her diet, and 72.2% adhered to the disease. The average score of the Medication Adherence Self-Efficacy Scale was calculated as 64.24 ± 16.89, whereas the total score average of the Multidimensional Perceived Social Support Scale was calculated as 53.74 ± 23.30. Besides, a statistically significant positive correlation was found among Medication Adherence Self-Efficacy Scale score average, Multidimensional Perceived Social Support Scale total score, and all subgroup score averages (P = .000).In conclusion, in this study, treatment adherence and social support levels of the patients were found to be substantially good; besides, adherence to drug treatment was found to increase positively as the social support of patients with hypertension increase.

Barriers and Facilitators of Using Sensored Medication Adherence Devices in a Diverse Sample of Patients With Multiple Myeloma: Qualitative Study

Background

Many recently approved medications to manage multiple myeloma (MM) are oral, require supportive medications to prevent adverse effects, and are taken under complex schedules. Medication adherence is a concern; however, little attention has been directed toward understanding adherence in MM or associated barriers and facilitators. Advanced sensored medication devices (SMDs) offer opportunities to intervene; however, acceptability among patients with MM, particularly African American patients, is untested.

Objective

This study aimed to explore patients’ (1) perceptions of their health before MM including experiences with chronic medications, (2) perceptions of adherence barriers and facilitators, and (3) attitudes toward using SMDs.

Methods

An in-person, semistructured, qualitative interview was conducted with a convenience sample of patients being treated for MM. Patients were recruited from within an urban, minority-serving, academic medical center that had an established cancer center. A standardized interview guide included questions targeting medication use, attitudes, adherence, barriers, and facilitators. Demographics included the use of cell phone technology. Patients were shown 2 different pill bottles with sensor technology—Medication Event Monitoring System and the SMRxT bottle. After receiving information on the transmission ability of the bottles, patients were asked to discuss their reactions and concerns with the idea of using such a device. Medical records were reviewed to capture information on medication and diagnoses. The interviews were audio-recorded and transcribed. Interviews were independently coded by 2 members of the team with a third member providing guidance.

Results

A total of 20 patients with a mean age of 56 years (median=59 years; range=29-71 years) participated in this study and 80% (16/20) were African American. In addition, 18 (90%, 18/20) owned a smartphone and 85% (17/20) were comfortable using the internet, text messaging, and cell phone apps. The average number of medications reported per patient was 13 medications (median=10; range=3-24). Moreover, 14 (70%, 14/20) patients reported missed doses for a range of reasons such as fatigue, feeling ill, a busy schedule, forgetting, or side effects. Interest in using an SMD ranged from great interest to complete lack of interest. Examples of concerns related to the SMDs included privacy issues, potential added cost, and the size of the bottle (ie, too large). Despite the concerns, 60% (12/20) of the patients expressed interest in trying a bottle in the future.

Conclusions

Results identified numerous patient-reported barriers and facilitators to missed doses of oral anticancer therapy. Many appear to be potentially mutable if uncovered and addressed. SMDs may allow for capture of these data. Although patients expressed concerns with SMDs, most remained willing to use one. A feasibility trial with SMDs is planned.

Perceived Postoperative Support Differentiates Responders from Non-Responders 3 Years After Laparoscopic Roux-en-Y Gastric Bypass

BACKGROUND

Bariatric surgery is an effective intervention for the majority of patients with morbid obesity, but a significant minority fails to achieve substantial weight loss. In the search of possible predictors of weight loss following bariatric surgery, preoperative factors turn out to have limited predictive power. This study will examine the impact of two postoperative factors on weight loss: perceived social support and stressful life events.

METHODS

From the entire 2013 cohort that underwent laparoscopic Roux-and-Y gastric bypass (LRYGB) in a general hospital in the Netherlands, a group of 56 non-responders and a matched group of 56 responders were selected, using an alterable weight loss (%AWL)-based percentile chart. Patients from both groups were interviewed by phone to collect data on demographics, medical complications and comorbidities, social support and stressful life events. A total of 61 patients completed the data collection (54% response rate).

RESULTS

One-way ANOVA analysis showed that responders and non-responders differed with regard to perceived support (F(1) = 8.60, p = .005). In a model with place of birth, level of education and pre-surgery diabetes mellitus as covariates, perceived social support was able to classify 83.6% of patients correctly as either responder or non-responder (χ ² = 28.26, p < .001). Stressful life events turned out to be unrelated to weight loss.

CONCLUSIONS

Perceived social support differentiates responders from non-responders after LRYGB. When patients present themselves after LRYGB with sub-optimal weight loss, social support should be a focus of attention.

Relationship between social engagement and diabetes incidence in a middle-aged population: Results from a longitudinal nationwide survey in Japan

AIMS/INTRODUCTION

Social engagement can positively affect health status, but its effect on diabetes incidence remains unclear. The present study aimed to assess the relationship between social engagement and diabetes incidence in a middle-aged Japanese population.

MATERIALS AND METHODS

We analyzed data on 31,615 people aged 50-59 years from a prospective national survey carried out in Japan from 2005 to 2013. Diabetes incidence was measured by asking respondents annually whether they had been diagnosed with diabetes by a physician in the previous year. We used the complementary log-log model for interval-censored survival time analysis. Social engagement was assessed at baseline as participation in social activities, having the companionship of friends, living with someone and employment status. Covariates including sex, age, health status and health behaviors were also measured at baseline.

RESULTS

After adjusting for covariates measured at baseline, the effect size of social engagement on diabetes incidence was the same as or larger than that of the covariates. Respondents who participated in social activities (hazard ratio [HR] 0.89, 95% confidence interval [CI] 0.87-0.92), had the companionship of friends (HR 0.97, 95% CI: 0.95-1.00), lived with someone (HR 0.85, 95% CI: 0.82-0.89) and were employed (HR 0.94, 95% CI: 0.92-0.96) were significantly less vulnerable to diabetes than were those who did not.

CONCLUSIONS

The present study found a prospective association between social engagement and diabetes incidence among a middle-aged population. Future strategies to prevent diabetes in Japan should focus on both social and personal factors.

Association of functional and structural social support with medication adherence among individuals treated for coronary heart disease risk factors: Findings from the REasons for Geographic and Racial Differences in Stroke (REGARDS) study

Background

Functional social support has a stronger association with medical treatment adherence than structural social support in several populations and disease conditions. Using a contemporary U.S. population of adults treated with medications for coronary heart disease (CHD) risk factors, the association between social support and medication adherence was examined.

Methods

We included 17,113 black and white men and women with CHD or CHD risk factors aged ≥45 years recruited 2003–2007 from the REasons for Geographic and Racial Differences in Stroke (REGARDS) study. Participants reported their perceived social support (structural social support: being partnered, number of close friends, number of close relatives, and number of other adults in household; functional social support: having a caregiver in case of sickness or disability; combination of structural and functional social support: number of close friends or relatives seen at least monthly). Medication adherence was assessed using a 4-item scale. Multi-variable adjusted Poisson regression models were used to calculate prevalence ratios (PR) for the association between social support and medication adherence.

Results

Prevalence of medication adherence was 68.9%. Participants who saw >10 close friends or relatives at least monthly had higher prevalence of medication adherence (PR = 1.06; 95% CI: 1.00, 1.11) than those who saw ≤3 per month. Having a caregiver in case of sickness or disability, being partnered, number of close friends, number of close relatives, and number of other adults in household were not associated with medication adherence after adjusting for covariates.

Conclusions

Seeing multiple friends and relatives was associated with better medication adherence among individuals with CHD risk factors. Increasing social support with combined structural and functional components may help support medication adherence.

Predictors of Changes in Medication Adherence in Blacks with Hypertension: Moving Beyond Cross-Sectional Data

BACKGROUND

Many studies have examined the multiple correlates of non-adherence in Blacks. However, they are largely cross-sectional; thus, these studies are unable to examine their predictive value on long-term medication adherence.

PURPOSE

The purpose of this study is to examine the predictive role of key psychosocial and interpersonal factors on changes in medication adherence over a 1-year period.

METHODS

Data were collected from 815 Black patients with hypertension followed in community health centers. Hypothesized predictor variables included self-efficacy, depressive symptoms, social support, and patient-provider communication measured at baseline, 6, and 12 months. The dependent variable, medication adherence was assessed at baseline, 6, and 12 months. Latent Growth Modeling was used to evaluate the pathways between the latent predictor variables and medication adherence.

RESULTS

Participants were mostly female, low-income, with high school education or less, and mean age of 57 years. At baseline, high self-efficacy was associated with low depressive symptoms (β = -0.22, p = 0.05), collaborative patient-provider communication (β = 0.17, p = 0.006), and better medication adherence (β = 1.04, p < 0.001). More social support and collaborative patient-provider communication were associated with low depressive symptoms (β = -0.08, p = 0.02; β = -0.18, p = 0.01). More social support was positively associated with collaborative patient-provider communication (β = 0.32, p < 0.001). In the longitudinal model, increasing self-efficacy over time predicted improvements in medication adherence 1 year later (β = 1.76, p < 0.001; CFI = 0.95; RMSEA = 0.04; SRMR = 0.04; Chi-Squared Index of Model Fit = 1128.54).

CONCLUSIONS

Self-efficacy is a key predictor of medication adherence over time in Black patients with hypertension. Initial levels of self-efficacy are influenced by the presence of depressive symptoms as well as the perceived quality of patient-provider communication.

Impact of Gender on Satisfaction and Confidence in Cholesterol Control Among Veterans at Risk for Cardiovascular Disease

BACKGROUND

Compared with men, women have poorer lipid control. Although potential causes of this disparity have been explored, it is unknown whether patient-centered factors such as satisfaction and confidence contribute. We evaluated (1) whether satisfaction with lipid control and confidence in ability to improve it vary by gender and (2) whether sociodemographic characteristics modify the association.

MATERIALS AND METHODS

We evaluated baseline survey responses from the Cardiovascular Intervention Improvement Telemedicine Study, including self-rated satisfaction with cholesterol levels and confidence in controlling cholesterol. Participants had poorly controlled hypertension and/or hypercholesterolemia.

RESULTS

A total of 428 veterans (15% women) participated. Compared with men, women had higher low-density lipoprotein values at 141.2 versus 121.7 mg/dL, respectively (p < 0.05), higher health literacy, and were less likely to have someone to help track their medications (all p < 0.05). In an adjusted model, women were less satisfied with their cholesterol levels than men with estimated mean scores of 4.3 versus 5.6 on a 1-10 Likert scale (p < 0.05). There was no significant difference in confidence by gender. Participants with support for tracking medications reported higher confidence levels than those without, estimated mean 7.8 versus 7.2 (p < 0.05).

CONCLUSIONS

Women veterans at high risk for cardiovascular disease were less satisfied with their lipid control than men; however, confidence in ability to improve lipid levels was similar. Veterans without someone to help to track medications were less confident, and women were less likely to have this type of social support. Lack of social support for medication tracking may be a factor in lingering gender-based disparities in hyperlipidemia.

Adjusting to Chronic Health Conditions

Research on adjustment to chronic disease is critical in today's world, in which people are living longer lives, but lives are increasingly likely to be characterized by one or more chronic illnesses. Chronic illnesses may deteriorate, enter remission, or fluctuate, but their defining characteristic is that they persist. In this review, we first examine the effects of chronic disease on one's sense of self. Then we review categories of factors that influence how one adjusts to chronic illness, with particular emphasis on the impact of these factors on functional status and psychosocial adjustment. We begin with contextual factors, including demographic variables such as sex and race, as well as illness dimensions such as stigma and illness identity. We then examine a set of dispositional factors that influence chronic illness adjustment, organizing these into resilience and vulnerability factors. Resilience factors include cognitive adaptation indicators, personality variables, and benefit-finding. Vulnerability factors include a pessimistic attributional style, negative gender-related traits, and rumination. We then turn to social environmental variables, including both supportive and unsupportive interactions. Finally, we review chronic illness adjustment within the context of dyadic coping. We conclude by examining potential interactions among these classes of variables and outlining a set of directions for future research.

Accountability: a missing construct in models of adherence behavior and in clinical practice

Piano lessons, weekly laboratory meetings, and visits to health care providers have in common an accountability that encourages people to follow a specified course of action. The accountability inherent in the social interaction between a patient and a health care provider affects patients' motivation to adhere to treatment. Nevertheless, accountability is a concept not found in adherence models, and is rarely employed in typical medical practice, where patients may be prescribed a treatment and not seen again until a return appointment 8-12 weeks later. The purpose of this paper is to describe the concept of accountability and to incorporate accountability into an existing adherence model framework. Based on the Self-Determination Theory, accountability can be considered in a spectrum from a paternalistic use of duress to comply with instructions (controlled accountability) to patients' autonomous internal desire to please a respected health care provider (autonomous accountability), the latter expected to best enhance long-term adherence behavior. Existing adherence models were reviewed with a panel of experts, and an accountability construct was incorporated into a modified version of Bandura's Social Cognitive Theory. Defining accountability and incorporating it into an adherence model will facilitate the development of measures of accountability as well as the testing and refinement of adherence interventions that make use of this critical determinant of human behavior.

The influence of frailty syndrome on medication adherence among elderly patients with hypertension

BACKGROUND

Hypertension affects about 80% of people older than 80 years; however, diagnosis and treatment are difficult because about 55% of them do not adhere to treatment recommendations due to low socioeconomic status, comorbidities, age, physical limitations, and frailty syndrome.

AIMS

The purposes of this study were to evaluate the influence of frailty on medication adherence among elderly hypertensive patients and to assess whether other factors influence adherence in this group of patients.

METHODS AND RESULTS

The study included 296 patients (mean age 68.8±8.0) divided into frail (n=198) and non-frail (n=98) groups. The Polish versions of the Tilburg Frailty Indicator (TFI) for frailty assessment and 8-item Morisky Medication Adherence Scale for adherence assessment were used. The frail patients had lower medication adherence in comparison to the non-frail subjects (6.60±1.89 vs 7.11±1.42; P=0.028). Spearman's rank correlation coefficients showed that significant determinants with negative influence on the level of adherence were physical (rho =-0.117), psychological (rho =-0.183), and social domain (rho =-0.163) of TFI as well as the total score of the questionnaire (rho =-0.183). However, multiple regression analysis revealed that only knowledge about complications of untreated hypertension (β=0.395) and satisfaction with the home environment (β=0.897) were found to be independent stimulants of adherence level.

CONCLUSION

Frailty is highly prevalent among elderly hypertensive patients. Higher level of frailty among elderly patients can be considered as a determinant of lower adherence. However, social support and knowledge about complications of untreated hypertension are the most important independent determinants of adherence to pharmacological treatment.
