Barriers to initiating insulin therapy in patients with type 2 diabetes mellitus in public-sector primary health care centres in Cape Town

Barriers and Facilitators in Access to Diabetes, Hypertension, and Dyslipidemia Medicines: A Scoping Review

Objective: Identify barriers and facilitators in access to medicines for diabetes, hypertension, and dyslipidemia, considering patient, health provider, and health system perspectives. Methods: Scoping review based on Joanna Briggs methodology. The search considered PubMed, Cochrane Library, CINAHL, Academic Search Ultimate, Web of Science, SciELO Citation Index, and grey literature. Two researchers conducted screening and eligibility phases. Data were thematically analyzed. Results: The review included 219 documents. Diabetes was the most studied condition; most of the evidence comes from patients and the United States. Affordability and availability of medicines were the most reported dimension and specific barrier respectively, both cross-cutting concerns. Among high- and middle-income countries, identified barriers were cost of medicines, accompaniment by professionals, long distances to facilities, and cultural aspects; cost of transportation emerges in low-income settings. Facilitators reported were financial accessibility, trained health workers, medicines closer to communities, and patients' education. Conclusion: Barriers and facilitators are determined by socioeconomic and cultural conditions, highlighting the role of health systems in regulatory and policy context (assuring financial coverage and free medicines); providers' role bringing medicines closer; and patients' health education and disease management.

Healthcare Professionals' Views of Factors Influencing Diabetes Self-Management and the Utility of a mHealth Application and Its Features to Support Self-Care

INTRODUCTION

The perspectives of healthcare professionals (HCPs) are pivotal to co-development of self-management strategies for patients with diabetes. However, literature has been largely limited to perspectives of patients within the context of a Western healthcare setting. This study aims to explore factors influencing diabetes self-management in adult patients with diabetes from the perspectives of HCPs and their views of the value of mHealth application for diabetes self-management.

MATERIALS AND METHODS

We conducted focus group discussions (FGD) with purposively selected HCPs in Singapore. All FGDs were audio-recorded and transcribed verbatim. Thematic analysis was conducted using NVivo 12.

RESULTS

A total of 56 HCPs participated in the study. Barriers to self-management included limited patient commitment to lifestyle changes, suboptimal adherence to medication and treatment, patient resistance to insulin initiation and insufficient rapport between patients and HCPs. Patients' perceived susceptibility to complications, social support from family and community, multidisciplinary team care and patient's understanding of the benefits of self-care were viewed as facilitating self-management. HCPs saw mHealth apps as a vital opportunity to engage patients in the self-management of conditions and empower them to foster behavior changes. Yet, there were concerns regarding patient's limited digital literacy, lack of integration into routine electronic system and reluctance.

DISCUSSION

We identified a set of factors influencing self-management in adult patients with diabetes and useful app features that can empower patients to manage their conditions. Findings will inform the development of a mHealth application, and its features designed to improve self-care.

Attitudes and beliefs of South African primary healthcare practitioners on initiating insulin in people with type 2 diabetes: Findings from the Tshwane Insulin Project (TIP)

AIMS

To investigate the attitudes and beliefs of primary healthcare practitioners (HCPs) towards initiating insulin therapy for people with type 2 diabetes (T2D) in South Africa.

METHODS

A cross-sectional survey was conducted amongst HCPs from 23 clinics. The nurses' questionnaire was administered by research nurses while doctors completed an online version about their attitudes, beliefs and perceived barriers to initiating insulin.

RESULTS

Of the 73 HCPs surveyed, 68% were nurses and 84% were women. Only 24% of HCPs believed that most patients would eventually need to initiate insulin regardless of their adherence to treatment regimens and 86% preferred to delay insulin therapy. Doctors were reluctant to initiate insulin, citing patient-related reasons such as low socio-economic level (41%), inability to refrigerate insulin (77%) and inability to self-monitor blood glucose (55%). Doctors mentioned that patient behaviour including not adhering to treatment regimen and appointments (91%) and reluctance to start insulin therapy (82%) influenced their prescription practices. Doctors mentioned that health system factors, including the pressure to see patients quickly (68%) and lack of continuity of care (64%) were barriers to initiating insulin.

CONCLUSIONS

Optimising insulin therapy in primary care requires health system changes including promoting person-centred care and continuing training for HCPs.

Willingness of people with Type 2 diabetes to start insulin therapy: Evidence from the South African Tshwane Insulin Project (TIP)

AIMS

To determine factors associated with 'hypothetical willingness' to start insulin among people with Type 2 diabetes (T2DM).

METHODS

A quantitative cross-sectional study with insulin-naïve T2DM patients at 23 primary care facilities in the Tshwane Metropolitan Municipality. Data collected included demographic and clinical data, willingness to start insulin, attitudes and barriers to insulin therapy. Factors associated with unwillingness to start insulin therapy were explored using a multivariable logistic regression model.

RESULTS

Of 468 T2DM study patients (mean age 57.2, SD = 11.3 years), more than half (51.9%) expressed unwillingness to starting insulin therapy. Unwillingness was associated with negative attitudes (OR = 1.32, 95% CI = 1.12-1.55, p = 0.001) and reluctance (OR = 1.41, 95% CI = 1.27-1.57, p < 0.001) rather than age, sex, education or diabetes duration. The strongest reasons for patient unwillingness were injection anxieties, fear of needles, insufficient knowledge of insulin, feeling unable to cope with insulin and concerns about out-of-pocket costs.

CONCLUSIONS

The prospect of insulin therapy disturbs patients' sense of self and their psychological wellbeing. The high prevalence of psychological insulin resistance among these T2DM patients needs to be addressed for effective diabetes management.

The Unmet Medical Needs of Current Injectable Antidiabetic Therapies in China: Patient and Health Care Professional Perspectives

PURPOSE

Patients with diabetes and health care professionals (HCPs) play important roles in effective application of injectable antidiabetic therapies (IATs). However, their concerns and opinions on IATs are rarely investigated in China. This study aims to assess unmet medical needs of IATs regarding patient concerns, patient satisfaction, aspects that need improvement, and training burden from patient and HCP perspectives.

METHODS

This cross-sectional survey was conducted in 12 representative Chinese cities from December 2018 to January 2019. Patients with adult type 2 diabetes who were receiving IAT currently and had received IAT continuously for at least 1 month before the survey, endocrinologists with ≥5 years of experience and prescribing IAT in the past 1 month, and nurses with ≥3 years of experience and providing IAT training in the past 1 month were eligible participants. The patient survey assessed concerns of initiating IAT, satisfaction with IAT, aspects of IAT that need improvement, and IAT training received. The HCP survey evaluated patient concern of initiating IAT, aspects of IAT that need improvement, experience of providing IAT training, and self-reported burden of training. Descriptive statistical analysis was performed.

FINDINGS

In total, 500 patients, 200 endocrinologists, and 100 nurses were surveyed. The mean (SD) age of patients was 55.1 (11.8) years, with a disease duration of 7.6 (6.4) years. Of all patients, 391 (78.2%) were insulin users and 109 (21.8%) were glucagon-like peptide 1 receptor agonist users. Of the top 4 concerns about initiating IAT, both patients and endocrinologists reported inconvenience of daily injection (58.0% of patients and 68.5% of endocrinologists), worries about insulin dependence (42.6% of patients and 62.5% of endocrinologists), and fear of injection (37.0% of patients and 66.5% of endocrinologists). Medical expenses, convenience of drug portability and storage, and injection site reactions were the top 3 aspects that need improvement according to both patients and HCPs. High injection frequency was also one of the most urgent aspects for improvement (mean urgency score, 3.8 for physicians and 4.0 for nurses). A typical IAT training session took a mean (SD) of 14.1 (9.7) minutes. Both patients and HCPs considered injection operation after dose is set and symptoms and treatment for adverse effects as the 2 most time-consuming training contents. In addition, 97.1% of endocrinologists who provided training and 97.0% of nurses thought a more user-friendly IAT would reduce their training burden.

IMPLICATIONS

Study results indicate that the IATs with more convenient drug portability and storage, fewer injection site reactions and adverse events, less injection frequency, more user-friendly design, and fewer steps for injection might help improve patient experience with self-injection and reduce HCPs' training burden.

Exploring the Experiences of West African Immigrants Living with Type 2 Diabetes in the UK

The increasing prevalence and poorer management of Type 2 diabetes among West African immigrants in the UK is a public health concern. This research explored the experiences of West African immigrants in the management of Type 2 diabetes in the UK using a constructivist grounded theory approach. In-depth individual interviews were conducted with thirty-four West African immigrants living with Type 2 diabetes in the London area. Fifteen male and nineteen female adult West African immigrants with age range from 33-82 years participated in the study. Participants were recruited from five diabetes support groups and community settings. Initial, focused and theoretical coding, constant comparison and memos were used to analyse collected data. Three concepts emerged: Changing dietary habits composed of participants' experiences in meeting dietary recommendations, improving physical activity concerned with the experience of reduced physical activity since moving to the UK and striving to adapt which focus on the impact of migration changes in living with Type 2 diabetes in the UK. These address challenges that West African immigrants experience in the management of Type 2 diabetes in the UK. The findings of this research provide a better understanding of the influencing factors and can be used to improve the support provided for West Africans living with Type 2 diabetes in the UK, presenting a deeper understanding of socio-cultural factors that contribute to supporting individuals from this population.

Individualised targets for insulin initiation in type 2 diabetes mellitus-the influence of physician and practice: a cross-sectional study in eight European countries

OBJECTIVES

To determine at what glycated haemoglobin (HbA1c) level physicians from eight European countries would initiate insulin in type 2 diabetes, which physician or practice related factors influenced this level and whether physicians would differentiate between a younger uncomplicated patient and an older patient with comorbidities.

DESIGN

Cross-sectional study with data from the Guideline Adherence to Enhance Care study.

SETTING AND PARTICIPANTS

410 physicians from both primary and secondary care from Belgium, France, Germany, Italy, Ireland, Sweden, the Netherlands and the UK.

OUTCOME MEASURES

Physicians were asked at which HbA1c level they would initiate insulin for a young, uncomplicated patient (vignette 1) and for an older, complicated patient (vignette 2). We evaluated differences in HbA1c levels between physicians from different countries using analysis of variance. To identify physician and practice related factors associated with HbA1c level at initiation of insulin, we performed multivariable linear regression. Multiple imputation was used to deal with missing data.

RESULTS

In Germany, Ireland, Sweden, the Netherlands and the UK, the HbA1c levels for initiating insulin in vignette 2 (range: 60.0 to 66.0 mmol/mol; 7.6% to 8.2%) were higher than for vignette 1 (range: 57.2 to 64.2 mmol/mol; 7.4% to 8.0%). In multivariable analysis, the HbA1c level at which insulin was initiated only differed between countries (vignette 1): Dutch physicians initiated insulin at a lower HbA1c level compared with Belgium, France and the UK. No physician or practice factors were independently associated with HbA1c level at insulin initiation.

CONCLUSIONS

When deciding on individualised HbA1c targets for insulin initiation, physicians from five countries took patient's age and comorbidity into account. The HbA1c level at which physicians would initiate insulin therapy differed between countries.

Evaluation of psychological resistance to insulin treatment in type II diabetic patients

AIMS

Various studies have demonstrated that the majority of the factors affecting the reluctance of individuals to insulin injections are rooted in psychological factors. Present study aimed to determine relationships between main causes of refusal to insulin injection in diabetic patients and factors such as age, gender, and educational degree of patients.

MATERIAL & METHODS

This was a descriptive study which was conducted on diabetic patients (n = 505) who need insulin therapy. The data were collected with a questionnaire in following steps. First, the most important causes of patients' reluctance, in the patients' opinion, to insulin therapy were determined using the data of the previous studies. In the second step, the patients were asked to express their opinion on each of these factors and the recorded responses were analyzed.

RESULTS

The results of the study showed that fear of ampoules, fear of pain caused by insulin and the embarrassment of patients from injections in public significantly depended on the gender of the patients, so that these factors were much lower in men than women. In addition, these factors in the patients with higher degrees of education led to lower level of refusal to insulin injections. Another factor influencing the reluctance to insulin injections was the forming of a sense of addiction due to daily insulin injections, which was significantly lower among the patients with higher education, but did not have a significant relationship with sex of the patients. In this regard, another factor was fear of hypoglycemia and insulin side effects, which did not have a significant relationship with gender and educational degree. In addition, there was no significant relationship between the patient's age and any of the factors effective in patients' reluctance to insulin injections.

CONCLUSION

Psychological factors seem to be effective in the emergence of the sense of reluctance to insulin injections. Therefore, not only patients but also the entire society need to receive training and appropriate services to improve their attitude to this issue with a psychological approach and help to solve this problem.

Barbados Insulin Matters (BIM) study: Perceptions on insulin initiation by primary care doctors in the Caribbean island of Barbados

AIMS

With regards to insulin initiation in Barbados we explored primary care doctor (PCD) perception, healthcare system factors and predictors of PCD reluctance to initiate insulin.

METHODS

PCDs completed a questionnaire based on the theory of planned behaviour (TPB) and a reluctance to initiate insulin scale. Using linear regression, we explored the association between TPB domains and the reluctance to initiate insulin scale.

RESULTS

Of 161 PCDs, 70% responded (75 private and 37 public sector). The majority felt initiating insulin was uncomplicated (68%) and there was benefit if used before complications developed (68%), but would not use it until absolutely necessary (58%). More private than public sector PCDs (p<0.05) thought that the healthcare system allowed enough flexibility of time for education (68 vs 38%) and initiating insulin was easy (63 vs 35%), but less thought system changes would help initiating insulin (42 vs 70%). Reasons for reluctance to initiate insulin included patient nonadherence (83%) and reluctance (63%). Only the attitudes and belief domain of the TPB was associated with the reluctance to initiate insulin scale (p<0.001).

CONCLUSIONS

Interventions focusing on PCD attitudes and beliefs and restructuring services inclusive of the use of diabetes specialist nurses are required.

Barriers that practitioners face when initiating insulin therapy in general practice settings and how they can be overcome

AIM

To explore primary care physicians’ perspectives on possible barriers to the use of insulin.

METHODS

This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Eight electronic databases were searched (between January 1, 1994 and August 31, 2014) for relevant studies. A search for grey literature and a review of the references in the retrieved studies were also conducted. Studies that focused on healthcare providers’ perspectives on possible barriers to insulin initiation with type 2 diabetic patients were included, as well as articles suggesting solutions for these barriers. Review articles and studies that only considered patients’ perspectives were excluded.

RESULTS

A total of 19 studies met the inclusion criteria and were therefore included in this study: 10 of these studies used qualitative methods, 8 used quantitative methods and 1 used mixed methods. Studies included a range of different health care settings. The findings are reported under four broad categories: The perceptions of primary care physicians about the barriers to initiate insulin therapy for type 2 diabetes patients, how primary care physicians assess patients prior to initiating insulin, professional roles and possible solutions to overcome these barriers. The barriers described were many and covered doctor, patient, system and technological aspects. Interventions that focused on doctor training and support, or IT-based decision support were few, and did not result in significant improvement.

CONCLUSION

Primary care physicians’ known delay in insulin initiation is multifactorial. Published reports of attempts to find solutions for these barriers were limited in number.

Detection and Management of Diabetes during Pregnancy in Low Resource Settings: Insights into Past and Present Clinical Practices

Background. Timely and adequate treatment is important to limit complications of diabetes affecting pregnancy, but there is a lack of knowledge on how these women are managed in low resource settings. Objective. To identify modalities of gestational diabetes detection and management in low and lower middle income countries. Methods. We conducted a scoping review of published literature and searched the databases PubMed, Web of Science, Embase, and African Index Medicus. We included all articles published until April 24, 2016, containing information on clinical practices of detection and management of gestational diabetes irrespective of publication date or language. Results. We identified 23 articles mainly from Asia and sub-Saharan Africa. The majority of studies were conducted in large tertiary care centers and hospital admission was reported in a third of publications. Ambulatory follow-up was generally done by weekly to fortnightly visits, whereas self-monitoring of blood glucose was not the norm. The cesarean section rate for pregnancies affected by diabetes ranged between 20% and 89%. Referral of newborns to special care units was common. Conclusion. The variety of reported provider practices underlines the importance of promoting latest consensus guidelines on GDM screening and management and the dissemination of information regarding their implementation.
