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

Validation and application of the Insulin Treatment Appraisal Scale in Cuban patients with type 2 diabetes mellitus

INTRODUCTION

The purpose of this study was to validate the Insulin Treatment Appraisal Scale (ITAS) in the Cuban population with type 2 diabetes mellitus.

MATERIAL AND METHODS

A cross-sectional, multicentre analytical study was performed in Cuba from February 2020 to April 2021; 199 patients were surveyed in a hospital institution and in primary healthcare. We used the Insulin Treatment Appraisal Scale, consisting of 20 items, with a minimum score of 20 points and a maximum of 100, where the higher the score, the worse the perception of insulin therapy. The validity of the instrument was determined by means of an exploratory factor analysis. The internal consistency and reliability of the scale were calculated by means of Cronbach's alpha coefficient. A K-means cluster analysis was performed to establish a cut-off point for poor perception of insulin therapy.

RESULTS

The exploratory factor analysis supported the validity of the instrument, with a Cronbach's alpha of 0.747. There were statistically significant differences between patients under insulin and non-insulin treatment in terms of the answers given in all items of the scale. The total mean score obtained was 51.96 ± 10.78, and it was lower in insulin users compared to those who used other drugs (49.79 ± 10.07 vs 55.09 ± 11.12). A score ≥65 was proposed as a cut-off point for poor perception of insulin therapy. A positive relationship was found between the body mass index values and the total score of the scale. Being female and current treatment not involving insulin were factors associated with low perception of insulin therapy.

CONCLUSIONS

The instrument proved to be valid for the population in which it was applied. Insulin users turned out to be the ones with the best perception about its use. A cut-off point of ≥65 points for poor perception of insulin treatment was proposed for evaluation and comparison in future studies in other patient populations.

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.

Physician related barriers towards insulin therapy at primary care centres in Trinidad: a cross-sectional study

BACKGROUND

Physician related factors with respect to insulin therapy can contribute to diabetes mellitus (DM) mismanagement. Patient related factors have been previously explored in a Trinidad survey. The main objective of this study was to explore primary care physicians' (PCPs) related barriers towards insulin therapy.

METHODS

A cross-sectional study on a convenience sample of PCPs in the public primary care system was done using an online survey.

RESULTS

Of the 170 PCPs contacted, 75 (44%) responded. There were 47 females (62.7%) and 28 males (37.3%) with a mean age of 35.9 yrs. Nearly 40% of physicians admitted that the education given to patients was inadequate to allow initiation of insulin therapy. Half the respondents admitted to insufficient consultation times and inadequate appointment frequency to allow for intensification of insulin therapy. Forty percent of PCPs admitted that HbA1c results were unavailable to guide their management decisions. Only 6.7% of physicians said they had access to rapid acting insulin, while 5.3% said they had access to insulin pens.

CONCLUSION

PCPs in Trinidad treating diabetes at the public primary care clinics face several barriers in administering proper insulin therapy. Addressing these factors can improve glycemic control in this population.

An integrative review on facilitators and barriers in delivering and managing injectable therapies in chronic conditions: A part of the ACNAP project 'injectable medicines among patients with cardiovascular conditions'

INTRODUCTION

Although preventive health and therapeutics have benefited from advances in drug development and device innovation, translating these evidence-based treatments into real-world practice remains challenging.

AIM

The current integrative review aims to identify facilitators and barriers and perceptions in delivering and managing injectable therapies from patient perspectives.

METHODS

An integrative review was conducted in the databases of PubMed, CINAHL, PsycINFO and Cochrane. Keywords were used "Injectable therapy", "IV therapy", "SC therapy", "long term injectable therapies", "self-administered injectable therapy", "patients", "caregivers", "family", "carers", "facilitators", "barriers", "perspectives", "needs", "expectations", "chronic disease", "cardiovascular disease" linked with the words "OR" and "AND". The search was limited from January 2000 to July 2019. Inclusion and exclusion criteria were used.

RESULTS

Twenty studies were identified from the literature search. Studies followed qualitative, quantitative methodology and mixed methods. Facilitators included: health improvement, prevention of disease complications, taking control of their disease, effectiveness of the medication and convenience in management. Barriers included: fear of needles, insulin will cause harm, poor perception of the benefits of injectable therapies on their quality of life, inconvenience in self-management, social stigma, impact on daily living, financial barriers, lack of education. Perceptions included: 'treatment of last resort', 'life becomes less flexible', 'injectables were punishment/restriction', 'personal failure of self-management'.

CONCLUSION

Evidence shows how to create effective communication and shared decision-making relationships to provide best possible care to patients who need injectable therapy and support for self-management. Future research might help guide response to the fears and barriers of the patients using patients' perspectives.

[Level of knowledge about insulinization by Primary Care physicians and its impact on diabetes control]

OBJECTIVE

To determine the level of knowledge and current management of starting insulin treatment by Primary Care physicians, and its impact on metabolic control.

MATERIALS AND METHODS

A mainly qualitative exploratory sequential study, with a phenomenological approach, followed by a quantitative phase. The study included 37 primary care physicians from the Andalusian Health Service. Socio-demographic and clinical care variables were analysed. Univariate and bivariate analyses were performed.

RESULTS

There was a wide variability between Primary Care physicians in the level of knowledge of treatment with insulins (low knowledge: 13.5%; medium knowledge: 59.5%; high knowledge: 27.0%). There was a direct relationship between the level of knowledge and the attainment of HbA1c goals (as the level of knowledge increased, the metabolic control improved). The most common basal insulins prescribed were insulin glargine U-100 (56.8%), followed by insulin glargine U-300 (29.7%), and neutral protamine hagedorn (NPH) insulin (8.1%). There was a trend to show a different prescription pattern with basal insulins (as the level of knowledge decreased, the prescription of mixed and NPH insulins increased). More than one-third (35.1%) of primary care physicians did not know more complex patterns of treatment with insulins.

CONCLUSIONS

Only 27% of Primary Care physicians had a high knowledge about treatment with insulins. There was a direct relationship between the level of knowledge about insulins and glycaemic control. It is necessary to improve the knowledge about insulin therapy in order to optimise metabolic control and reduce the risk of complications.

The Barbados Insulin Matters (BIM) study: Barriers to insulin therapy among a population-based sample of people with type 2 diabetes in the Caribbean island of Barbados

AIM

The purpose of this study was to document in people with type 2 diabetes (T2DM) in Barbados, attitudes and beliefs that may result in psychological insulin resistance.

METHODS

A representative, population-based, sample of 175 eligible people with T2DM 25 years of age and over was surveyed by telephone. The 20-item insulin treatment appraisal scale (ITAS) was administered (score range 20 to 100 for positive to negative perceptions).

RESULTS

117 people participated (67% response rate, 32% male, mean age 66 years, 90% Black, 22% on insulin). Of non-responders, 52 were not contactable and 6 were difficult to communicate with. Negative perceptions about insulin use included - meant a worsening of diabetes (68%), would worry family (63%), feared self-injection (58%), meant a failure in self-management (57%), injections were painful (54%), would be seen as being sicker (46%), increased hypoglycaemia risk (38%), required effort (34%), causes weight gain (27%), causes a deterioration in health (14%), and would have to give up enjoyable activities (10%). Positive perceptions were - helps good glycaemic control (78%), would prevent complications (61%) and improves health (58%). Mean total ITAS score (61.6, SD = 7.7) was lower for those on insulin compared to those not on insulin (53.7 vs. 63.8, p < 0.0001). Sex, age and diabetes diagnosis duration were not significant predictors of ITAS score.

CONCLUSIONS

Multiple factors related to patient beliefs and attitudes need to be considered and addressed when initiating insulin in order to minimise psychological insulin resistance and delay. Patients using insulin had less negative perceptions than those not on insulin.
