Patient perspectives on medication self-management in rural Kenya: a cross-sectional survey

Measuring patient engagement with HIV care in sub-Saharan Africa: a scoping study

INTRODUCTION

Engagement with HIV care is a multi-dimensional, dynamic process, critical to maintaining successful treatment outcomes. However, measures of engagement are not standardized nor comprehensive. This undermines our understanding of the scope of challenges with engagement and whether interventions have an impact, complicating patient and programme-level decision-making. This study identified and characterized measures of engagement to support more consistent and comprehensive evaluation.

METHODS

We conducted a scoping study to systematically categorize measures the health system could use to evaluate engagement with HIV care for those on antiretroviral treatment. Key terms were used to search literature databases (Embase, PsychINFO, Ovid Global-Health, PubMed, Scopus, CINAHL, Cochrane and the World Health Organization Index Medicus), Google Scholar and stakeholder-identified manuscripts, ultimately including English evidence published from sub-Saharan Africa from 2014 to 2021. Measures were extracted, organized, then reviewed with key stakeholders.

RESULTS AND DISCUSSION

We screened 14,885 titles/abstracts, included 118 full-texts and identified 110 measures of engagement, categorized into three engagement dimensions ("retention," "adherence" and "active self-management"), a combination category ("multi-dimensional engagement") and "treatment outcomes" category (e.g. viral load as an end-result reflecting that engagement occurred). Retention reflected status in care, continuity of attendance and visit timing. Adherence was assessed by a variety of measures categorized into primary (prescription not filled) and secondary measures (medication not taken as directed). Active self-management reflected involvement in care and self-management. Three overarching use cases were identified: research to make recommendations, routine monitoring for quality improvement and strategic decision-making and assessment of individual patients.

CONCLUSIONS

Heterogeneity in conceptualizing engagement with HIV care is reflected by the broad range of measures identified and the lack of consensus on "gold-standard" indicators. This review organized metrics into five categories based on the dimensions of engagement; further work could identify a standardized, minimum set of measures useful for comprehensive evaluation of engagement for different use cases. In the interim, measurement of engagement could be advanced through the assessment of multiple categories for a more thorough evaluation, conducting sensitivity analyses with commonly used measures for more comparable outputs and using longitudinal measures to evaluate engagement patterns. This could improve research, programme evaluation and nuanced assessment of individual patient engagement in HIV care.

How the Term 'Self-Management' is Used in HIV Research in Low- and Middle-Income Countries: A Scoping Review

This scoping review assessed how the term 'self-management' (SM) is used in peer-reviewed literature describing HIV populations in low- and middle-income countries (LMIC). This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews. OVID Medline, Embase, CAB Abstracts, and EBSCO CINAHL, Scopus, and Cochrane Library were searched up to September 2021 for articles with SM in titles, key words, or abstracts. Two team members independently screened the titles and abstracts, followed by the full-text. A data extraction tool assisted with collecting findings. A total of 103 articles were included. Since 2015, there has been a 74% increase in articles that use SM in relation to HIV in LMIC. Fifty-three articles used the term in the context of chronic disease management and described it as a complex process involving active participation from patients alongside providers. Many of the remaining 50 articles used SM as a strategy for handling one's care by oneself, with or without the help of community or family members. This demonstrates the varied conceptualizations and uses of the term in LMIC, with implications for the management of HIV in these settings. Future research should examine the applicability of SM frameworks developed in high-income settings for LMIC.

National Trends in Hospitalization for Ambulatory Care Sensitive Conditions among Korean Adults between 2008 and 2019

PURPOSE

This study aimed to examine 12-year trends in hospitalization rates for ambulatory care sensitive conditions (ACSC) and factors affecting hospitalization.

MATERIALS AND METHODS

This study used data on Korean National Health Insurance and Medical Aid patients aged 19 and over who used medical services at least once between January 2008 and December 2019 with an ACSC as their major diagnosis. As of 2019, a total of 12324071 patients were included. To check for any changes in hospitalization, age- and sex-standardized hospitalization rates were obtained for each condition and insurance type, and multiple logistic regression was performed to identify factors affecting hospitalization.

RESULTS

The collective average ACSC hospitalization rate decreased from 5.0% in 2008 to 4.2% in 2019. Specifically, hospitalization rates for hypertension (1.4% in 2008; 0.8% in 2019), diabetes (5.8% in 2008; 3.3% in 2019), and chronic obstructive pulmonary disease and asthma (4.1% in 2008; 3.2% in 2019) decreased, while rates for pneumonia (24.5% in 2008; 28.1% in 2019) and urinary tract infection (UTI) (5.7% in 2008; 6.4% in 2019) increased. The rate for heart failure decreased 2.3% between 2008 and 2012 and then rebounded. The odds of hospitalization among Medical Aid patients were 1.45-4.20 times higher than those of National Health Insurance patients.

CONCLUSION

Differences in trends were confirmed for ACSC hospitalization rates among different conditions and insurance types in Korea. These results suggest the need for policy reforms aimed at reducing hospitalization for heart failure, pneumonia, and UTI, especially among Medical Aid patients.

Development and validation of self-management scale for tuberculosis patients

Background

Tuberculosis remains a major threat to global public health. Regarding its control, directly observed therapy is not suitable as a global strategy for all tuberculosis patients. Self-management may be an important patient-centered tuberculosis case management supplement to directly observed therapy. However, there is currently no well-established instrument for measuring the self-management of tuberculosis patients. This study aimed to develop and validate a self-management scale for tuberculosis patients.

Methods

We developed an initial scale based on the tuberculosis health promotion indicators framework developed by our research group. After item analysis and two rounds of exploratory factor analysis, a final version of the scale was developed. A survey of 462 tuberculosis patients was conducted to develop and validate this scale. Cronbach’s α and intraclass correlation coefficients were used to assess reliability, and Pearson’s correlation coefficients were used to evaluate content validity. Fit indices, convergent validity, and discriminant validity were evaluated using confirmatory factor analysis to determine the construct validity of the scale.

Results

The scale was composed of 17 items in three dimensions (“adherence to treatment behavior,” “transmission prevention behavior,” and “supportive therapy behavior”). These three dimensions explained 76.60% of the variance. Cronbach’s α of the scale was 0.905, and the intraclass correlation coefficient was 0.897. Additionally, Pearson’s correlation analysis showed that each item was strongly correlated with the dimension to which it belonged (r = 0.849–0.915, p < 0.01). Most fit indices (Comparative Fit Index, Normed Fit Index, Incremental Fit Index, Goodness of fit index) reached the recommended threshold, and the average variance extracted values of the three dimensions were higher than 0.5. The values of the square root of the average variance extracted within each dimension were greater than the correlation between dimensions, and all heterotrait–monotrait values were below 0.85.

Conclusions

The self-management scale for tuberculosis patient demonstrated good reliability and validity and could be used as an instrument to evaluate the self-management of patients. Additionally, it could be used to develop evidence-based self-management interventions and evaluate those interventions.

Health behaviours and beliefs among Malawian adults taking antihypertensive medication and antiretroviral therapy: A qualitative study

In order to understand HIV-positive Malawian adults' experiences with hypertension management, we conducted qualitative interviews with 30 hypertensive adults who were also taking antiretroviral therapy. These interviews regarding hypertension management behaviours and beliefs were audio-recorded, transcribed, translated into English, and coded in Atlas.ti. Despite acknowledging the dangers of hypertension and the benefits of medication, many respondents missed their antihypertensive medication. Primary reasons included feeling healthy, health workers' advice to stop taking medicine when blood pressure normalised, side effects, and using herbs or non-prescription medicines to manage hypertension. Women highlighted difficulties with dietary modifications, and changes in their social relationships. Both men and women spoke about hypertension-related challenges with employment and household economics. These results suggest numerous challenges among adults managing hypertension and HIV in Malawi, and frequent suboptimal adherence to medication. We identified new key themes - the quality of adherence counselling for antihypertensive medication, the effects of hypertension on financial stability, and the role of social relationships in self-care - and encourage further investigation into these topics in low-income, high-burden countries.
