Insulin Injection Technique in China Compared with the Rest of the World

Design and Testing of a Smartphone Application for Real-Time Tracking of CSII and CGM Site Rotation Compliance in Patients With Type 1 Diabetes

INTRODUCTION

Glycemic control in patients with type 1 diabetes can be difficult to achieve. One critical aspect of insulin delivery is site rotation, which is necessary to reduce dermatologic complications of repeated insulin infusion. No current application is designed to help patients track sites and instruct on overused sites.

OBJECTIVE

The objectives of this study were to (1) design a smartphone app, Insulin Site Guide, to gather real-time information on continuous subcutaneous insulin infusion (CSII) and continuous glucose monitor (CGM) site location and rotation compliance and instruct subjects on the use of an overused site; (2) conduct a usability study to measure site rotation compliance; and (3) report subject satisfaction with the app.

DESIGN

The app is installed on the subject's smartphone. Subjects use the app to record CSII and CGM placement in real-time. Data are sent to the study team at the end of the study. Subjects complete a questionnaire concerning the app.

RESULTS

We report site rotation compliance data for eight subjects and survey responses for 10 subjects. Initial data from eight subjects indicate a high site rotation compliance of 84% for insulin pumps. In general, the majority of users indicate high satisfaction with the app.

CONCLUSIONS

Insulin Site Guide is a mobile app that uses a novel algorithm to better guide site rotation. Use of the app has the potential to improve site rotation and decrease dermatologic complications of diabetes with long-term use.

Fabrication and characterization of coated microneedle patches based on PEGDA for transdermal administration of metformin

Type 2 diabetes is one of the major challenges that the world is facing today. However, metformin (MET) as most type 2 diabetics' first-line oral hypoglycemic drug may cause serious side effects such as gastrointestinal irritation and nausea which reduce the patients' medication compliance. Therefore, the aim of the study was to design a safe and effective self-treatment device for the delivery of MET. Here, a kind of coated microneedle (MN) patches based on poly(ethylene glycol)diacrylate (PEGDA) were prepared by a two-step casting method and photopolymerization process for transdermal administration of MET. The needles wrapped with drug-loaded hyaluronic acid (HA) coating showed promising mechanical properties and drug delivery ability that allowed them to penetrate the skin barrier for rapid drug delivery, and they had no skin irritancy. The in vivo experiment of type 2 diabetic rats showed a satisfying hypoglycemic effect of the coated MN patches. The study shows that the prepared MN patches will be a potential method for the treatment of type 2 diabetes in the future.

Expert Opinion on Addressing the Gap in Injection Technique and Needle Reuse for People with Diabetes in Indonesia

The use of insulin for patients with diabetes mellitus in Indonesia appears to be under expectation; moreover, there are gaps in knowledge regarding the proper injection technique and pen needle reuse by both healthcare professionals (HCPs) and patients. To address these issues, a scientific expert meeting was held with the participation of endocrinologists and public health specialist from many different organizations in Indonesia to identify the challenges and problem related to injection technique, high pen needle reuse rate, and the need of all stakeholders. The experts agreed that it is necessary to ensure physicians to start the initiation phase as early as indicated, continue optimizing its dosage to reach targeted blood sugar based on guideline, and involve all relevant stakeholders to improve insulin distribution and patient access in every primary care facility in order to optimize the use of insulin or other injectable diabetes medications in Indonesia. Additionally, the experts believed that education on proper injection technique and improved reuse rate of pen needle is necessary. To date, Indonesian Diabetes Educators Association (IDEA/PEDI) has established guideline on injection technique. There are also recommendations on injection technique and needle reuse from Indonesian Society of Endocrinology (PERKENI) and Forum for Injection Technique & Therapy: Expert Recommendations (FITTER); however, this guideline/recommendation should be disseminated more widely among HCPs. In addition, cost-effectiveness studies based on local data are needed to propose and convince the Payors and other stakeholders. This article can be used as a guidance for HCPs and policymakers to improve current practice on injection technique, pen needle reuse, needle prescription and reimbursement policy in Indonesia and elsewhere.

A Nationwide Cross-sectional Survey of Knowledge and Practices of Diabetes Drug Injection Techniques of Patients, Nurses, and Physicians: The China IT Improve Study

OBJECTIVE

To investigate the knowledge and practices of diabetes drug injection techniques of diabetes patients, nurses, and physicians to support formulating national guidelines for standardized diabetes drug injection techniques.

PATIENTS AND METHODS

In this nationwide multicenter cross-sectional survey conducted between November and December 2020, patients, nurses, and physicians were randomly chosen from 250 primary, 150 secondary, and 100 tertiary care hospitals using the stratified cluster sampling method. Their knowledge and/or practices of diabetes drug injection techniques were surveyed using the Diabetes Drug Injection Knowledge and Practice Questionnaire for Physicians, Nurses, and Patients.

RESULTS

In total, 10,694, 2643, and 2816 eligible questionnaires were collected from patients, physicians, and nurses, respectively. Overall, 78.2% (7588/9709) type 2 diabetes patients failed to attain the target hemoglobin A1c. Hypoglycemic episodes and lipohypertrophy occurred in 19.8% and 34.7% of the patients, respectively. Needle reuse (odds ratio, 1.19; 95% CI, 1.07 to 1.33) and incorrect injection site rotation (odds ratio, 1.32; 95% CI, 1.16 to 1.51) were associated with failure to attain the target hemoglobin A1c. Overall, 48.9% physicians and 20.4% nurses had a poor knowledge domain score. Care setting and training, diabetes care experience, and regions were significant determinants of diabetes drug injection knowledge domain scores in both physicians and nurses.

CONCLUSION

Poor glycemic control, occurrences of injection-associated complications in diabetes patients, and poor knowledge domain scores of a subset of physicians and nurses highlight the importance of regular assessment and education regarding diabetes drug injection techniques for physicians and nurses and development of national guidelines for diabetes drug injection.

Insulin injection knowledge, attitude and behaviour of nurses: A cross-sectional study in Guangdong Province

AIM

To understand the insulin injection knowledge, attitude and behaviour of nurses and their influencing factors in Guangdong Province.

DESIGN

Cross-sectional study.

METHODS

A total of 19,853 nurses from 82 hospitals in 15 cities in Guangdong, China, participated in this study. The scores of the nurses' insulin injection knowledge, attitude and behaviour were determined through a questionnaire, and multivariate regression analysis was used to evaluate the influencing factors of insulin injection in different dimensions. STROBE.

RESULTS

Among all nurses involved in this study, 22.3% of nurses had good knowledge, 75.9% of nurses had good attitude and 92.7% of nurses had good behaviour. Pearson's correlation analysis showed that knowledge, attitude scores and behaviour scores were significantly correlated. The influencing factors of knowledge, attitude and behaviour included gender, age, education, nurse level, work experience, type of ward, diabetes nursing certification, position held and most recent insulin administration.

Insulin Injection Knowledge, Attitudes, and Practices of Nurses in China: A Cross-Sectional Nationwide Study

INTRODUCTION

To evaluate insulin injection knowledge, attitudes, and practices of nurses across China in order to provide reference for the formulation of a national unified standard of insulin injection practice and the targeted implementation of standardized training on insulin injection for nurses.

METHODS

We enrolled nurses who worked and injected insulin at grassroot hospitals including community health service centers and township clinics, secondary and tertiary care hospitals across China between July 28, 2019 and August 30, 2019. A nurse insulin injection knowledge, attitude, and practice questionnaire was used to evaluate the knowledge, attitude, and practice level of nurses.

RESULTS

A total of 223,368 nurses were included in the study. The mean knowledge score was 13.70 ± 3.30 and 35.19% had a poor knowledge score. The mean attitude score was 17.18 ± 2.69 for the study nurses; merely 3.15% had a poor attitude score. The mean practice score of the study population was 83.03 ± 8.16 and only 0.88% had a poor practice score. Pearson correlation analysis showed significant correlation between the knowledge score and the attitude score (r = 0.29; P < 0.001), the knowledge score and the practice score (r = 0.27; P < 0.001), and between the attitude score and the practice score (r = 0.56; P < 0.001). A multivariate analysis revealed that nurses with higher knowledge scores were also more likely to have higher attitude scores and practice scores, and nurses with higher attitude scores were also more likely to have higher practice scores.

CONCLUSION

Chinese nurses have a good attitude and behavior towards insulin injection, while their knowledge of insulin injection is insufficient. It is also revealed that knowledge of insulin injection can directly or indirectly affect insulin injection behavior through attitude, indicating that hospitals should formulate unified insulin injection norms and regularly organize relevant training and assessment so as to improve nurses' knowledge, attitude, and behavior of insulin injection.

Values of ultrasound for diagnosis and management of insulin-induced lipohypertrophy: A prospective cohort study in China

The aim of this study was to explore the values of ultrasound for diagnosis and management of insulin-induced lipohypertrophy and further analyzing the impact of body mass index and subcutaneous fat thickness on ultrasound manifestations of lipohypertrophy.In this 3-month, prospective cohort study, a total of 162 patients with diabetes who used insulin therapy more than 1 year with unknown lipohypertrophy status were enrolled into this study. Demographic information, assessment of glycemic control and insulin injection technique were evaluated. Physical and ultrasound examination were separately performed to detect lipohypertrophy by a team of diabetes educator nurses or ultrasonographer in a blinded fashion. Patients with lipohypertrophy received insulin injection technique education based on ultrasound examination and Chinese guideline.Ultrasound examination detected 41.1% more patients (74.1% vs 52.5%; P < .001) with lipohypertrophy and 61.2% more lesions (216 vs 134; P < .001) than physical examination. Glycosylated hemoglobin A1c and fasting blood glucose were significantly decreased in patients with lipohypertrophy or subclinical lipohypertrophy (lipohypertrophy without visual and palpation changes) after receiving insulin injection technique education based on ultrasound examination and Chinese guideline than baseline at 3 months (P < .001). The proportion of lesions with ultrasound manifestation 2 (distortion of surrounding connective tissue) in obese and STF (>15 mm) groups were no more than 50% and showed a decreased trend with increased subcutaneous fat thickness and body mass index (P < .001).Lipohypertrophy has characteristic ultrasound manifestations which can detect more accurate results than palpation alone and provide detailed information to promote effective education on lipohypertrophy management, thereby improving glycemic control.

Insulin injection technique in the western region of Algeria, Tlemcen

Introduction

Algeria has more than 1.7 million diabetic patients on to whom a descriptive assessment particularly on the insulin usage behaviors has not yet been initiated, although is needed. This study aims to provide a descriptive analysis of how Algerian diabetic patients perceive and apply insulin injection techniques.

Methods

using the “patient” questionnaire within the Injection Technique Questionnaire (ITQ) 2016 survey, this study assessed the insulin injection practices of 100 patients recruited over a seven-month period in western Algeria at the Tlemcen University Hospital Center. The results of this study are compared to those of the ITQ 2016 survey.

Results

pens are the instruments of injection for 98% of Algerians who continue to use mostly long needles of 6- and 8-mm, although 4mm needles are the recommended safer option. Insulin analogues (fast and basal) are plebiscite. Arms and thighs are the preferred injection sites; the abdomen (the preferred site elsewhere) is neglected for reasons to be investigated. The correct re-suspension technique for cloudy insulin is unknown. Extensive pen needle re-use (10+ times) for over half of the patients exposes them to both higher intramuscular (IM) injection risk and lipohypertrophy (LH). Injection training is performed in Algeria by the diabetologist.

Conclusion

this study describes for the first time Algerian patients´ insulin injection technique. It highlights their skills and identifies many deficiencies which patients and professionals must correct given the issues in this area.
