Application of Andersen's behavioural model of health services use: a scoping review with a focus on qualitative health services research

INTRODUCTION

Qualitative methods have become integral in health services research, and Andersen's behavioural model of health services use (BMHSU) is one of the most commonly employed models of health service utilisation. The model focuses on three core factors to explain healthcare utilisation: predisposing, enabling and need factors. A recent overview of the application of the BMHSU is lacking, particularly regarding its application in qualitative research. Therefore, we provide (1) a descriptive overview of the application of the BMHSU in health services research in general and (2) a qualitative synthesis on the (un)suitability of the model in qualitative health services research.

METHODS

We searched five databases from March to April 2019, and in April 2020. For inclusion, each study had to focus on individuals ≥18 years of age and to cite the BMHSU, a modified version of the model, or the three core factors that constitute the model, regardless of study design, or publication type. We used MS Excel to perform descriptive statistics, and applied MAXQDA 2020 as part of a qualitative content analysis.

RESULTS

From a total of 6319 results, we identified 1879 publications dealing with the BMSHU. The main methodological approach was quantitative (89%). More than half of the studies are based on the BMHSU from 1995. 77 studies employed a qualitative design, the BMHSU was applied to justify the theoretical background (62%), structure the data collection (40%) and perform data coding (78%). Various publications highlight the usefulness of the BMHSU for qualitative data, while others criticise the model for several reasons (eg, its lack of cultural or psychosocial factors).

CONCLUSIONS

The application of different and older models of healthcare utilisation hinders comparative health services research. Future research should consider quantitative or qualitative study designs and account for the most current and comprehensive model of the BMHSU.

Health Care Analysis on Myocardial Revascularization in Patients with Chronic Coronary Artery Disease: The Multicenter REVASK Study: Design and Protocol

Coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) are available for revascularization of coronary artery disease (CAD) with the aims to reduce cardiovascular morbidity and mortality and to improve disease-related quality of life in particular. The German National Care Guideline (NVL-cKHK) on chronic CAD recommends the establishment of so-called heart teams for decision making in myocardial revascularization to improve the quality of care. Preferred recommendations for PCI or CABG are given for different patient subgroups depending on patient characteristics, concomitant diseases, and coronary morphology. The myocardial revascularization study (REVASK) is a noninterventional cohort study on care of patients undergoing PCI or CABG based on retrospective statutory health insurance (SHI) routine data, registry data from the German Cardiac Society (DGK) resp., the German Society for Thoracic and Cardiovascular Surgery (DGTHG), combined with prospective primary data collection from health care providers and patients. The primary goal is to investigate whether and to which extent heart teams, consisting of cardiologists and cardiac surgeons, increase guideline adherence in decision making for myocardial revascularization. Ultimately the study project aims to improve patient care in terms of decision making for appropriate myocardial revascularization. Through the consistent implementation of the German National Care Guideline on chronic Coronary Artery Disease (NVL-cKHK) and the European Guidelines on myocardial revascularization, the reduction of morbidity, mortality and the reduced need for subsequent revascularization procedures are also desirable from a health economics perspective.

[The WHO Concept of Active Aging from the Local Perspective: A Qualitative Survey in the District of Constance]

BACKGROUND

The WHO strategy for active aging comprises maintenance of health, participation in social life as well as integration and social security for the aged. As a political framework for action, the strategy supports the future aging policy of municipalities. This survey examines how local actors assess the WHO strategy of active aging.

METHODS

The study consists of 5 guided interviews of experts from the rural district of Constance. The interview was based on a previously coordinated list of indicators that summarize 102 recommendations for action. The awareness of the WHO strategy as well as a brief introduction to the 3 main areas provided the start of the interviews, followed by the comparison of municipal activities with the list of indicators, the identification of the need for action and of previous unrecognized aspects. In the sense of a data triangulation, we conducted a quantitative survey in further districts. The data of the interviews were analyzed by using the method of Gläser and Laudel, referred to as qualitative content analysis.

RESULTS

None of the interviewed experts knew the WHO strategy of active aging. However, after a short explanation of the WHO strategy and indicator list, they classified the strategy as practicable. All of them rated the recommendations for action from the sub-areas of participation in society (e.g. creation of advisory councils for seniors) and security in public space and transport (e.g. protection measures for older pedestrians) as feasible. In some areas, such as medical care and formal care, they missed indicators. Hence, we recommend adding new recommendations for action.

DISCUSSION

The awareness of local authorities regarding the WHO strategy of active aging should be improved. Taking into account the specified further development needs, active aging is a viable orientation aid and offers several opportunities for aging policy for municipalities.

A close look at lay-led self-management programs for chronic diseases and health care utilisation: A systematic review and meta-analysis

Introduction: Chronically ill people are confronted with significant challenges when dealing with health care services. Lay-led self-management programs aim to improve self-management skills and might enable patients to make appropriate decisions as to when to use health care services. Contrary to the general attitude that self-management programs reduce health care utilisation, we suspect that better self-management skills lead to increased or possibly more appropriate health care utilisation. Our review and meta-analysis sheds light on the relationship between lay-led self-management programs and health care utilisation. Methods: In March 2017, we searched 7 databases (CDSR, DARE, HTA, Medline, CINAHL, PsycInfo, and SSCI) to perform a systematic review and meta-analysis to identify studies that reported empirical data on lay-led self-management programs and health care utilisation. We extracted the characteristics of all primary studies and the data of four indicators of utilisation (physician visits, emergency department visits, hospital admissions, and length of stay in hospital), and analysed the role of health care utilisation in these studies. We present the results in frequency tables and as a conventional meta-analysis with the standardized mean difference (SMD), 95% confidence intervals (CI), and pooled overall effect sizes using RevMan 5.3.5. The manuscript follows the PRISMA checklist. Results: Overall, we include 49 primary studies; 10 studies provided sufficient data for the meta-analysis. Health care utilisation played a different role in the studies; 15 studies reported a clear explicit hypothesis on the influence of a lay-led self-management program on health care utilisation, and 17 studies assumed an implicit assumption. 8 studies discussed the possibility that a lay-led self-management program could lead to more appropriate health care utilisation. The meta-analysis showed mixed results, and many effect sizes were not statistically significant. The participants of a lay-led self-management program had fewer emergency department visits (SMD: -0.08; 95% CI: -0.15 to -0.01; p=0.02) than the control group. Conclusion: Although the statistically significant effects of the meta-analysis are low, our overall findings show that only a small number of the included studies tackled the task of comprehensively investigating self-management skills in the context of health care utilisation. This fails to do justice to the potential of self-management programs. It is essential to consider the appropriateness of health care utilisation. We propose the term self-management-sensitive utilisation for this purpose.

[Medical Rehabilitation as an Attractive Field of Work for Medical Doctors? - A Qualitative Survey]

In the German Health system there is an increasing competition in the recruitment of specialised staff, especially for rehabilitation centres, which are deemed less attractive. Therefore, this study examines the attractiveness of the field of medical rehabilitation from the point of view of medical professionals. We conducted 16 semi-structured interviews with doctors from 7 rehabilitation centres with different medical specialisations. The interviews were digitized and transcribed. A structured content analysis was carried out using the software MAXQDA 11. 745 codes were identified and assigned to the categories "attractiveness", "unfavourable aspects" and "special features" of rehabilitation. Regarding medical rehabilitation, the interviewees appreciated especially the predictable, flexible working environment with little time pressure. Other than working with rehabilitative patients working as part of an interdisciplinary team was of high importance for the interviewees. Among the special features of rehabilitation in comparison with acute care were the higher relevance of the bio-psycho-social model of health and illness as well as the higher proportion of communication and organisation. Medical rehabilitation in Germany is an attractive field of work for medical doctors. This fact should be considered more with regards to rehabilitation's public image.

Interaction of human beta-endorphin with nonopiate binding sites on the terminal SC5b-9 complex of human complement. Significance of COOH-terminal beta H-endorphin fragments

We have characterized the binding of 125I-labeled human beta-endorphin (125I-beta H-endorphin) to sites present on the terminal fluid-phase complex of human complement, consisting of complement components C5b, C6, C7, C8, C9, and the S-protein (SC5b-9 complex). Specific binding exhibited saturability, reversibility, structural specificity, temperature dependence, and absence of negative cooperative effects. Binding was maximal at 4 degrees C and pH 7.0; it was diminished by monovalent and divalent cations as well as by increasing concentrations of urea and Triton X-100 and apparently required intact disulfide groups. Binding was not inhibited by a number of opioid peptides sharing common sequences with the NH2 terminus of beta H-endorphin. In contrast, binding was inhibited by beta H-endorphin, N-acetyl-beta H-endorphin, and a series of COOH-terminal beta H-endorphin fragments, where of the COOH-terminal dipeptide Gly-Glu represented the minimal effective structure. Stepwise extension towards the NH2 terminus led to an increased binding affinity of the respective fragment. Computer resolution of competition curves yielded one binding component for several shorter COOH-terminal beta H-endorphin fragments and for beta H-endorphin (1-5) + (16-31), whereas two distinct binding components were obtained when beta H-endorphin (27-31), beta H-endorphin (6-31), N-acetyl-beta H-endorphin or beta H-endorphin were used as inhibitors. This study presents detailed data on the binding of COOH-terminal beta H-endorphin fragments to specific nonopiate binding sites present on the terminal SC5b-9 complex of human complement. We suggest that through this interaction, beta H-endorphin may modulate certain functions within the immune system.
