Determinants of health-related quality of life: a cross-sectional investigation in physician-managed anticoagulated patients using vitamin K antagonists

Barriers to self-monitoring implementation in the oral anticoagulated population: A qualitative study

AIM

This study aimed to explore and understand the barriers perceived by Italian nurses to adopting self-monitoring for managing oral anticoagulation in real-life settings.

BACKGROUND

Barriers to self-monitoring implementation for managing oral anticoagulation have been poorly described.

DESIGN

The study had a qualitative descriptive and exploratory design with a hybrid approach.

METHODS

A literature review was conducted to identify a priori barriers (deductive approach), while a small and semi-structured focus group discussion was performed to explore the contextual barriers experienced by Italian nurses (inductive approach). A classic content analysis technique was adopted. Data were collected in 2019.

FINDINGS

Two main categories were identified. Organizational barriers referred to the lack of inter-professional collaboration and health-care system strategies to provide clinical pathways for self-monitoring. Individual barriers encompassed professional characteristics (e.g. university background, professional knowledge, continuum education and accountability/responsibility) and patient characteristics (e.g. patient health literacy and knowledge, engagement/empowerment and educational programmes). Finally, unwarranted clinical variation in oral anticoagulation management arose as a barrier determined by organizational and individual elements.

CONCLUSIONS

The results of this study pointed out an urgent public health issue in addressing barriers influencing self-monitoring practice and in sustaining care models that might enhance the quality improvement of self-monitoring for managing oral anticoagulation.

The effect of health literacy on vaccine hesitancy among Italian anticoagulated population during COVID-19 pandemic: the moderating role of health engagement

Assessing vaccine hesitancy and its determinants is pivotal to optimize vaccine acceptance in anticoagulated patients, given that this population has been described to have a higher risk of severe COVID-19-related complications. This study assessed the moderator role of patients' health engagement on the relationship between health literacy and vaccine hesitancy. A web-based survey was performed in Italy during the first wave (June-August 2020) and the second wave (October 2020-March 2021) of the COVID-19 pandemic, enrolling 288 patients. The rates of vaccine hesitancy reported during the first pandemic wave were 38.4% and 30.8% during the second wave (when a vaccine was available) (p = .164). A moderation analysis was performed to assess the role of health engagement in influencing the relationship from health literacy to vaccine hesitancy. Patients' health engagement enhanced the effects of health literacy on decreasing vaccine hesitancy (p < .001), suggesting that co-construction strategies for communicative action are pivotal.

Is SF-12 a valid and reliable measurement of health-related quality of life among adults with Marfan syndrome? A confirmatory study

Introduction

The structural validity and reliability of the Short-Form Health Survey 12 (SF-12) has not yet been tested in adults with the Marfan syndrome (MFS). This gap could undermine an evidence-grounded practice and research, especially considering that the need to assess health-related quality of life in patients with MFS has increased due to the improved life expectancy of these patients and the need to identify their determinants of quality of life. For this reason, this study aimed to confirm the dimensionality (structural validity) of the SF-12, its concurrent validity, and its reliability (internal consistency).

Methods

We performed a cross-sectional study in a convenience sample of 111 Italian adults with MFS, collecting anamnestic and socio-demographic information, the SF-12, and short-form Health Survey 36 (SF-36). A confirmatory factor analysis was performed to verify whether the items of SF-12 related to physical restrictions, physical functioning, and bodily pain were retained by the physical summary component of the SF-12. The items referred to the role limitations due to emotional issues, social functioning, and mental health were retained by the mental summary component (MCS12). SF-36 was used to assess the concurrent validity of SF-12, hypothesizing positive correlations among the equivalent summary scores.

Results

The two-factor structural solution resulted in fitting the sample statistics adequately. The internal consistency was adequate for the two factors. Furthermore, the physical and mental summary scores of the SF-36 were positively correlated with their equivalent summary scores derived from the SF-12.

Conclusions

This study confirmed the factor structure of the SF-12. Therefore, the use of SF-12 in clinical practice and research for assessing the health-related quality of life among adults with MFS is evidence-grounded. Future research is recommended to determine whether the SF-12 shows measurement invariance in different national contexts and determine eventual demographic variation in the SF-12 scores among patients with MFS.

Nursing self-efficacy for oral anticoagulant therapy management: Development and initial validation of a theory-grounded scale

AIM

This study aimed to develop and validate a nursing self-efficacy scale for OAC management (SE-OAM).

BACKGROUND

Oral anticoagulant therapy (OAC) requires specific nursing competencies. Given that self-efficacy acts as a proxy assessment of nursing competence, its measurement is pivotal for addressing educational programs to enhance nursing competence in managing OAC. Thus far, the measurement of self-efficacy in OAC is undermined by the unavailability of valid and reliable tools.

METHODS

A multi-method and multi-phase design was adopted: Phase one was a methodological study encompassing developmental tasks for generating items. Phase two comprised the validation process for determining the content validity, construct and concurrent validity, and internal consistency through two cross-sectional data collections.

RESULTS

In total, 190 nurses were enrolled for determining the psychometric structure of the SE-OAM through an exploratory approach, and 345 nurses were subsequently enrolled to corroborate its most plausible factor structure derived from the exploratory analysis. The SE-OAM showed evidence of face and content validity, adequate construct, concurrent validity, good internal consistency, and stability. The final version of the scale encompassed 21 items kept by five domains: clinical management, care management, education, clinical monitoring, and care monitoring.

CONCLUSIONS

The SE-OAM showed evidence of initial validity and reliability, fulfilling a current gap in the availability of tools for measuring nursing self-efficacy in managing OAC. SE-OAM could be strategic for performing research to improve the quality of OAC management by enhancing nursing self-efficacy.
