The Impact of Peer Support Program on Adherence to the Treatment Regimen in Patients with Hypertension: A Randomized Clinical Trial Study

Medication Adherence among Primary Care Patients with Common Mental Disorders and Chronic Medical Conditions in Rural India

Background

Only a few studies have explored the relationship between psychosocial factors and medication adherence in Indian patients with noncommunicable diseases (NCDs). We aimed to examine the association of psychosocial variables with medication adherence in people with NCDs and comorbid common mental disorders (CMDs) from primary care in rural southern India.

Methods

We performed a secondary analysis using baseline data from a randomized controlled trial in 49 primary care health centers in rural southern India (HOPE study). Participants were adults (≥30 years) with NCDs that included hypertension, diabetes, and/or ischemic heart disease, and comorbid depression or anxiety disorders. Medication adherence was assessed by asking participants if they had missed any prescribed NCD medication in the past month. Data were collected between May 2015 and November 2018. The association between psychosocial and demographic variables and medication nonadherence were assessed via logistic regression analyses.

Results

Of the 2486 participants enrolled, almost one-fifth (18.06%) reported missing medication. Male sex (OR = 1.74, 95% CI 1.37-2.22) and higher internalized mental illness stigma (OR = 1.46, 95% CI 1.07-2.00) were associated with higher odds of missing medication. Older age (OR = 0.40, 95% CI 0.26-0.60, for participants aged 64-75 years vs 30-44 years), reporting more social support (OR = 0.65, 95% CI 0.49-0.86), and higher satisfaction with health (OR = 0.74, 95% CI 0.61-0.89) were associated with lower odds of missing medication.

Conclusions

Greater internalized mental illness stigma and less social support are significantly associated with lower rates of medication adherence in patients with NCDs and comorbid CMDs in rural India.

The impact of peer-led support groups on health-related quality of life, coping skills and depressive symptomatology for women with PCOS

Support groups can be a powerful medium in providing psychological support to women with Polycystic Ovary Syndrome (PCOS). The study evaluated the impact of peer support group on Health-Related Quality of Life (HRQoL), depressive symptomatology and coping strategies among women with PCOS. The pre- and post-test experimental design was used. Women with PCOS not receiving psychiatric medication and attending clinics of a teaching hospital in Colombo were recruited. They were randomly allocated based on clinic days to the experimental (n = 20) and control (n = 22) groups. The Intervention group participated in the specific peer support program for 10 weeks, while the control group received general health reading material for 10 weeks through the post. The Modified Polycystic Ovary Syndrome Questionnaire (M-PCOSQ), Centre for Epidemiologic Studies Depression Scale (CES-D) and Brief COPE inventory were administered to both groups before and 1 month after completing the intervention. Before the intervention, there was no significant difference between the two groups regarding the scores of HRQoL, depressive symptomatology and coping skills. One month after the intervention, the support group exhibited improvement in HRQoL, depressive symptomatology and coping skills (p < 0.01) compared to the control group. The peer support group is an effective intervention to uplift the psycho-social wellbeing of women with PCOS through receiving emotional support from those similarly afflicted.

Self-Care Behaviors in Patients with Hypertension to Prevent Hypertensive Emergencies: a Qualitative Study Based on the Theory of Planned Behavior

Background: Hypertension is a crucial general health issue. Severe and acute hypertension needs urgent medical intervention. Self-care behaviors can help patients with hypertension in controlling blood pressure and preventing hypertensive emergencies. This study aimed to determine the perception of hypertension towards self-care behaviors using constructs of the theory of planned behavior (TPB) in critically ill patients with hypertension to prevent hypertensive emergencies.

Material and Methods: This study was conducted based on the directed qualitative content analysis of 33 critically ill patients with hypertension who participated in semi-structured interviews and focus group discussions. Results: The data were analyzed based on the four main categories of TPB. The attitude category consisted of positive and negative subcategories. The subjective norms category consisted of authority of healthcare staff, family support and approval, and influence of friends subcategories. The perceived behavioral control category included discipline, self-control, receiving consultation, individual concerns, financial problems, access to medicine, food culture, and coronavirus limitations subcategories. The behavioral intention category had intention to perform the behavior and intention to continue a behavior subcategories.

Conclusion: The results revealed the requirement for a multidimensional approach to improve attitude, subjective norms, and behavioral control for performing self-care behaviors to reduce the number of hypertensive emergencies in critically ill patients with hypertension. Factors affecting self-care included socioeconomic status, family support, governmental organizations, and participants’ health condition.

Association between social participation and hypertension control among older people with self-reported hypertension in Japanese communities

Hypertension control remains poor worldwide despite well-established strategies for lowering blood pressure. Social participation has been associated with a lower prevalence of hypertension, but evidence is scarce regarding hypertension control. The aim of this study was to examine the relationship between social participation and hypertension control among older people. We used cross-sectional data from participants of the 2019 wave of the Japan Gerontological Evaluation Study (JAGES; n = 13,629). Social participation was defined as no participation, participation in one group, or participation in two or more groups. After adjusting for covariates, modified Poisson regression analysis showed that participation in two or more groups (prevalence ratio [95% confidence interval]: 1.08 [1.03-1.13]) was associated with better control of hypertension than no participation, but participation in one group (1.02 [0.96-1.08]) was not. Social participation in multiple groups was associated with better control of hypertension among older people in Japan.

The Effect of Peer Support on Foot Care in Patients with Type 2 Diabetes

Background:

Diabetes mellitus is one of the prevalent diseases in the world with several complications including diabetic foot ulcers. The aim of this study was to investigate the effect of peer support on foot care in patients with type 2 diabetes.

Materials and Methods:

This clinical trial study was performed at selected centers of Isfahan University of Medical Sciences in 2017. Fifty patients with type 2 diabetes were randomly assigned into intervention and control groups. Five 30-min. supportive training sessions were held for the intervention group by the peers and during 35 days. Foot Care Confidence/Foot-Care Behavior Scale For Diabetes (FCCS-FCB) was completed by both groups before, immediately after and 1 month after the intervention. Collected data were analyzed using Chi-square, Mann–Whitney, repeated measures ANOVA and t-test.

Results

: Mean (SD) age of subjects was 56.46 (7.36) years old Mean (SD) score of self-efficacy (F_{2, 26} = 54.71, p < 0.001), preventive behaviors (F_{2, 26} = 28.46, p < 0.001), and potentially damaging (F_{2, 26} = 27.89, p < 0.001) had significant differences between the two groups immediately and 1 month after the peer support.

Conclusions:

Peer support can enhance foot care behaviors in diabetic patients. Therefore, using people who are successful in the education and support of patients has a significant role, and nurses can use them as a support in the field of care and follow-up. However, health agencies are responsible for providing the patients with the best guidelines, and these results can be useful as an evidence for them.

The association between social support and medication adherence in patients with hypertension: A systematic review

Background:

Medication adherence is a primary determinant of treatment success in hypertensive patients. One of the challenges for healthcare providers that has received little attention is the impact of patients’ social supports on medication adherence.

Objective:

This review evaluates the impact of patients’ social supports on medication adherence in hypertensive patients.

Methods:

A systematic review methodology was used. Pubmed, CINAHL, Embase, and PsycINFO databases were searched systematically for relevant articles. The outcome measure in the studies was medication adherence in hypertension.

Results:

From 1155 articles, 238 were retained for further assessment, and finally, 14 met the inclusion criteria. Statistically significant positive associations between medication adherence and social support were found in nine studies (p<0.05).

Conclusions:

This review evaluated the impact of social support on medication adherence and highlighted gaps in the literature regarding the impact of social support on adherence. Family members or peer support may promote better adherence in some patient groups. This review suggests that healthcare providers may need to consider whether patients have appropriate social supports in place which will assist them adhering to and benefiting from treatment recommendations.

Medication Adherence Interventions for Cardiovascular Disease in Low- and Middle-Income Countries: A Systematic Review

PURPOSE

The burden of cardiovascular diseases (CVD) is high in low- and middle-income countries (LMICs). Medications are integral to the management and control of CVD; however, suboptimal adherence impacts health outcomes. This systematic review aims to critically examine interventions targeted at improving medication adherence among persons with CVD in LMICs.

METHODS

In this systematic review, we searched online databases PubMed, Embase, and CINAHL for studies that evaluated a medication adherence intervention for CVD, reported adherence as an outcome measure, were conducted in LMICs and reported the strategy or tool used to measure adherence. We included articles published in English, available in full text, peer-reviewed, and published between 2010 and 2020.

RESULTS

We included 45 articles in this review. The majority of the studies implemented counseling and educational interventions led by nurses, pharmacists, or community health workers. Many of the studies delivered medication-taking reminders in the form of phone calls, text messages, short message services (SMS), and in-phone calendars. Multi-component interventions were more effective than unifocal interventions. Interventions involving technology, such as mobile phone calls, electronic pillboxes, and interactive phone SMS reminders, were more effective than generic reminders. The outcomes reported in the studies varied based on the complexity and combination of strategies. When interventions were implemented at both the patient level, such as reminders, and at the provider level, such as team-based care, the effect on medication adherence was larger.

CONCLUSION

In LMICs, medication adherence interventions among persons with CVD included a combination of patient education, reminders, fixed-dose combination therapy and team-based care approach were generally more effective than singular interventions. Among patients who had CVD, the medication adherence interventions were found to be moderately effective. Future studies focusing on improving medication adherence in LMICs should consider non-physician-led interventions and appropriately adapt the interventions to the local context.

Promoting Health-Enhancing Physical Activity: a State-of-the-art Review of Peer-Delivered Interventions

PURPOSE OF REVIEW

In this review, we critically examined recent evidence pertaining to the efficacy of peer-delivered physical activity interventions.

RECENT FINDINGS

Peer-delivered interventions appear to represent an efficacious, although under-utilized, means of promoting health-enhancing physical activity, among diverse populations across the lifespan, and in different settings. Nevertheless, research has largely failed to identify the salient behaviors/strategies of peer leaders that can promote behavior change among target populations, as well as explanatory mechanisms (i.e., mediators) of intervention effects. Balanced against recent evidence for the efficacy of peer-delivered interventions to promote physical activity, work in this area appears impeded by an absence of peer-centric explanatory frameworks and theory that may optimize both intervention delivery and efficacy/effectiveness.

Adherence to lifestyle changes after coronary artery bypass graft: Outcome of preoperative peer education

OBJECTIVE

This study was done to investigate the effect of preoperative peer education on patients' adherence to medication and lifestyle changes after Coronary Artery Bypass Graft (CABG).

METHODS

In this randomized clinical trial, the peers of CABG patients conducted preoperative educational sessions at the ward in groups of 4-5 (n = 36) while the control group (n = 34) received routine education by a nurse. Adherence of both groups to medication and recommendations for lifestyle modification including physical activity, smoking, and diet was measured one and two months after discharge.

RESULTS

A multivariate analysis of co-variance showed the significant effect of peer education on adherence (F = 32.586, p < 0.001; η² = 0.671). Univariate ANCOVA revealed a significant difference in adherence to diet between the two groups (F = 62.316, p = 0 0.0001; η² = 0.482). Based on the repeated measures ANOVA, peer education significantly improved the CABG patients' adherence to diet (F = 55.373, p = 0.0001) and their total adherence (F = 9.911, p = 0.002) compared to the control group.

CONCLUSION

Preoperative peer education had a significant effect on improving CABG patients' adherence to lifestyle changes after hospital discharge.

PRACTICE IMPLICATION

Peer education can be used as an effective method to improve the CABG patients ' adherence to lifestyle changes.

El ritmo circadiano de la presión arterial y su relación con los factores de riesgo cardiovascular

Introducción: Numerosos estudios han establecido tanto la hipertensión arterial como la hipertensión de bata blanca como factores de riesgo cardiovascular. Un ritmo circadiano anómalo de la presión arterial podría aumentar el riesgo cardiovascular. Objetivo: Determinar la existencia de una relación clínicamente relevante entre un ritmo circadiano anómalo de la presión arterial y un incremento del riesgo cardiovascular en pacientes con hipertensión arterial o hipertensión de bata blanca. Material y Método: Estudio descriptivo en 166 pacientes mayores de 18 años del Área Básica de Salud de Balaguer que tuvieran una monitorización ambulatoria de la presión arterial realizada entre junio de 2014 y marzo de 2018 y cumplieran los criterios de inclusión y exclusión. Se realizó un análisis univariado y bivariado de las variables. Resultados: Se obtuvo que en casi todos los promedios de presión arterial nocturna destaca el patrón riser mostrando que el 25% tenía un riesgo cardiovascular mayor o igual al 10%, seguido del dipper extremo 16,67%, dipper 9,4% y no dipper 8,27%. Conclusión: Un ritmo circadiano alterado se relaciona con un riesgo cardiovascular más elevado y un peor control de los factores que conllevan al mismo.

Specific hypertension smartphone application to improve medication adherence in hypertension: a cluster-randomized trial

Introduction: Digital interventions, such as smartphone applications (apps), are becoming an increasingly common way to support medication adherence and self-management in chronic illness.Aim: To evaluate the effectiveness of the intervention in pharmacological therapeutic adherence in mild to moderate arterial hypertension (AHT), through an app installed on a mobile phone, as well as the degree of control reached by the patient with this tool.Methods: Prospective, randomized controlled trial, full study and multicenter study. Four primary care centers participated. One hundred and fifty-four hypertensive patients under antihypertensive treatment were included. Two groups were established: a control group (CG) with usual intervention (n = 77) and an intervention group (n = 77) (IG), targeting hypertensive people who owned and regularly used a mobile smartphone, specifically using the app called AlerHTA to promote health education and reminder of appointments. There were three visits: initial, 6 and 12 months. Drug adherence was measured by electronic monitors (MEMSs). The primary outcomes were average daily percentage adherence between 80 and 100%, and AHT control.Results: A total of 148 patients finished the study. Mean age was 57.5 ± 9.9. Global adherence was 77.02% (CI = 70.25-83.79) and daily adherence was 74.32% (CI = 67.29-81.35%). Daily adherence was 93.15% and 86.3% in IG, and 70.66% and 62.66% in CG after 6 and 12 months respectively (p < .05). The percentage of uncontrolled patients was 28.3% (CI = 21.05-35.55%). The control of high blood pressure at 12 months was 17.8% and 38.6% for IG and CG respectively (p < .05). The number of patients needed to treat to avoid non-adherence (NNT) was 4.23 patients.Conclusions: The intervention with an app installed on the mobile phones of hypertensive patients favors pharmacological therapeutic adherence and improves the percentage of hypertensive patient control.Trial registration: Spanish Agency of Medicine: EPA-SP UN-HTA-2015-01.
