Understanding strategies to improve medication adherence among persons with type 2 diabetes: A scoping review.

AIMS: The objectives of this scoping review were to: (1) identify the target audience and contexts in which strategies to improve type 2 diabetes mellitus (T2DM) medication adherence have been used, (2) provide an overview of behaviour change techniques (BCTs) used, (3) describe the determinants of behaviour targeted by strategies and (4) to identify current gaps in strategies. METHODS: A systemic search for articles related to T2DM, medication adherence and strategies was conducted in EMBASE, Ovid MEDLINE and Epub Ahead of Print, In-Process & Other Non-Indexed Citations and Daily using the OvidSP platform on 11 March 2021. All publications involving strategies to overcome medication non-adherence among adults with T2DM were included. Strategies were categorized according to the BCT taxonomy and the determinants of behaviour targeted by each strategy were classified by using the Theoretical Domains Framework (TDF). RESULTS: The search identified 58 articles and 61 strategies. The BCT categories Antecedents and Natural consequences and BCTs Feedback on outcome(s) of behaviour, Adding objects to the environment and Information about health consequences were identified most frequently as components of strategies resulting in statistically significant improvement in medication adherence. Strategies targeting the TDF domains Reinforcement and Beliefs about Consequences most often resulted in statistically significant improvements in adherence measures. CONCLUSIONS: The findings from this review identify BCTs and targeted behaviours with demonstrated success. Further exploration of the myriad of BCTs and the corresponding determinants of behaviour which were not accessed may be warranted for the development of future strategies to improve medication adherence in type 2 diabetes.

Persons With Diabetes and General/Family Practitioner Perspectives Related to Therapeutic Inertia in Type 2 Diabetes Mellitus Using Qualitative Focus Groups and the Theoretical Domains Framework: Results From the MOTION Study.

OBJECTIVES: Therapeutic inertia in type 2 diabetes (T2DM) is the failure to receive timely treatment intensification as indicated according to T2DM treatment guidelines. Multifactorial causes of therapeutic inertia in T2DM have been documented at the level of persons with diabetes (PwD), health-care providers and health-care systems. METHODS: We developed a 3-part mixed-methods research program, called the Moving to Overcome Therapeutic Inertia Obstacles Now in T2DM (MOTION) study, to inform the development of strategies to address therapeutic inertia in T2DM. We present the results from focus groups with the following objectives: 1) understanding PwD and general practitioner/family practitioner (GPFP) determinants of behaviour related to treatment intensification using the Theoretical Domains Framework (TDF); and 2) identifying the sources of behaviours contributing to therapeutic inertia in T2DM, as proposed by the Behaviour Change Wheel (BCW). Two focus groups with PwD and 4 with GPFPs were conducted. Transcripts from the focus groups were coded independently by 2 investigators to identify themes, then mapped to TDF domains and linked using the BCW. RESULTS: For PwD, the most commonly coded TDF domains were intentions, goals, knowledge, beliefs about consequences and social influences. For GPFPs, the most common domains were intentions, environmental context and resources and social/professional role and identity. The BCW identified that PwD interventions should include reflective motivation, psychological capability and social opportunity; GPFP interventions should include physical opportunity, social opportunity and reflective motivation. CONCLUSIONS: Comprehensive strategies that target both PwD and GPFP barriers would encourage a more collaborative approach toward treatment intensification decisions and reducing therapeutic inertia.

A Cross-sectional Survey to Assess Reasons for Therapeutic Inertia in People With Type 2 Diabetes Mellitus and Preferred Strategies to Overcome It From the Perspectives of Persons With Diabetes and General/Family Practitioners: Results From the MOTION Study.

OBJECTIVES: Although multiple causes of therapeutic inertia in type 2 diabetes mellitus (T2DM) have been identified, few studies have addressed the behavioural aspects of treatment-intensification decisions among persons with type 2 diabetes (PwT2DM) and general practitioners/family practitioners (GPFPs). METHODS: A quantitative online survey was developed to capture from 300 PwT2DM and 100 GPFPs the following information: 1) perspectives on shared decision-making (SDM) related to treatment intensification, using the 9-item Shared Decision Making Questionnaire and the Shared Decision Making Questionnaire---physician version; 2) intentions to intensify treatments, using the Theory of Planned Behaviour (TPB); and 3) preferred strategies to overcome causes of therapeutic inertia in T2DM. Regression methods were applied post hoc to examine correlations with SDM scores, behavioural intentions and behaviours. RESULTS: SDM scores showed a significantly lower level of perceived involvement in decision-making related to treatment intensification among PwT2DM compared with GPFPs. The TPB identified that, for PwT2DM, attitudes, perceived behavioural control and age were associated with variation in intention to intensify treatment and, for GPFPs, perceived behavioural control and not being in a shared/group practice were associated with intentions to intensify treatment. PwT2DM behaviour, measured as hesitancy to intensify treatment, was associated with age. PwT2DM want more information to become more comfortable with the treatment decision-making process, whereas GPFPs desired support from other health professionals, and more time to address issues among PwT2DM. CONCLUSIONS: Strategies directed at providing GPFPs with tools/approaches to increase PwT2DM involvement in the decision-making process, such as behavioural coaching, decision aids and goal setting, may increase acceptance of treatment intensification, leading to a reduction in therapeutic inertia in T2DM.

Strategies to Overcome Therapeutic Inertia in Type 2 Diabetes Mellitus: A Scoping Review.

The objectives of this review were to: 1) examine recent strategies and component interventions used to overcome therapeutic inertia in type 2 diabetes mellitus (T2DM), 2) map strategies to the causes of therapeutic inertia they target and 3) identify causes of therapeutic inertia in T2DM that have not been targeted by recent strategies. A systematic search of the literature published from January 2014 to December 2019 was conducted to identify strategies targeting therapeutic inertia in T2DM, and key strategy characteristics were extracted and summarized. The search identified 46 articles, employing a total of 50 strategies aimed at overcoming therapeutic inertia. Strategies were composed of an average of 3.3 interventions (range, 1 to 10) aimed at an average of 3.6 causes (range, 1 to 9); most (78%) included a type of educational strategy. Most strategies targeted causes of inertia at the patient (38%) or health-care professional (26%) levels only and 8% targeted health-care-system-level causes, whereas 28% targeted causes at multiple levels. No strategies focused on patients' attitudes toward disease or lack of trust in health-care professionals; none addressed health-care professionals' concerns over costs or lack of information on side effects/fear of causing harm, or the lack of a health-care-system-level disease registry. Strategies to overcome therapeutic inertia in T2DM commonly employed multiple interventions, but novel strategies with interventions that simultaneously target multiple levels warrant further study. Although educational interventions are commonly used to address therapeutic inertia, future strategies may benefit from addressing a wider range of determinants of behaviour change to overcome therapeutic inertia.

The geographic distribution of un-immunized children in Ontario, Canada: Hotspot detection using Bayesian spatial analysis.

BACKGROUND: In Ontario, Canada, little is currently known about the extent to which un-immunized children may cluster geographically. Our objectives were to: describe the geographic distribution of fully un-immunized children; identify geographic clusters (hotspots) of un-immunized children; and to characterize the contribution of spatial effects and covariates on hotspots, where found. METHODS: Our analytic cohort consisted of Ontario students aged 7-17 years in the 2016-2017 school year. We defined students as un-immunized if they had zero doses of any vaccine and a non-medical exemption recorded in Ontario's registry. We calculated unadjusted proportions of un-immunized students by Census Subdivision (CSD) and then used a sequential approach to identify hotspots starting first with hotspot identification at the CSD level and then probed identified hotspots further by Dissemination Area (DA) and including covariates. Hotspots were identified using the Besag-York-Mollie Bayesian spatial model and were defined as areas with >95% probability of having two times the proportion of un-immunized students, relative to the province overall. RESULTS: We identified 15,208 (0.94%) un-immunized children within our cohort consisting of more than 1.61 million students. Unadjusted proportions of un-immunized students varied greatly by geography, ranging from 0% to 21.5% by CSD. We identified 16 hotspot CSDs which clustered in five distinct areas, all of which were located in southern Ontario. The contribution of covariates and spatial effects on the risk of having un-immunized students varied greatly across hotspot areas. CONCLUSIONS: Although the provincial proportion (0.94%) of un-immunized students is small, geographical clustering of such students is evident in Ontario and in some areas presents an important risk for future outbreaks. Further qualitative work within these hotspot areas would be a helpful next step to better characterize the factors associated with vaccine refusal in these communities.

Assessing the completeness of infant and childhood immunizations within a provincial registry populated by parental reporting: A study using linked databases in Ontario, Canada.

INTRODUCTION: In Ontario, Canada, parents have the responsibility to report their child's routine infant and childhood vaccines to the provincial immunization registry (the Digital Health Immunization Repository; DHIR) without healthcare provider validation. Despite its use in routine immunization coverage monitoring, no study has previously examined the completeness of immunization data within the DHIR. METHODS: We assessed the completeness of DHIR immunizations, as compared to immunizations within the Electronic Medical Records-Primary Care (EMRPC) database, also known as EMRALD, a network of family physician electronic medical records (EMRs). We linked client records from the DHIR and EMRPC to a centralized population file. To create the study cohort, we examined children born during 2005-2008 and further defined the cohort based on those rostered to an EMRPC physician, visit criteria to ensure ongoing care by an EMRPC provider, and school attendance in Ontario at age 7. We calculated up-to-date (UTD) immunization coverage at age 7 for individual vaccines and overall using data from the DHIR and EMRPC separately, and compared the estimates. RESULTS: The analytic cohort to assess DHIR data completeness included 2,657 children. Overall UTD coverage (all vaccines assessed) was 82.0% in the DHIR and 67.6% in EMRPC. UTD coverage was higher in the DHIR for all vaccines assessed individually, with the exception of meningococcal C conjugate vaccine (difference = 0.3%). After excluding two EMRPC sites with irregularities in immunization data, the difference in overall UTD coverage between systems decreased from 14.4% to 6.6% INTERPRETATION: These results validate the use of DHIR for coverage assessment but also suggest that bidirectional exchange of immunization information has the potential to increase immunization data completeness in both systems.

Human Rabies Postexposure Prophylaxis Knowledge and Retention Among Health Professionals by Using an Online Continuing Education Module: Arizona, 2012 to 2015.

Rabies postexposure prophylaxis (PEP) is administered for rabies prevention after a human exposure to a potentially rabid animal, such as a bite. Previous studies have reported that rabies PEP is often inappropriately administered. Health professional education was proposed as one potential solution to address inappropriate PEP use. We assessed baseline knowledge, knowledge gain, and knowledge retention among health professionals in Arizona of rabies epidemiology and appropriate PEP administration. Maricopa County Department of Public Health created an online rabies PEP continuing education module and measured knowledge before and after module completion using a 10-question test. The same test was administered three times (pretest, posttest, and retention test at ≥3 months). To assess knowledge gain and retention, we compared median scores using nonparametric methods. A total of 302 respondents completed the pretest (median score, 60%) and posttest (median score, 90%; p < .001); 98 respondents completed all three tests with median scores 60% (pretest), 90% (posttest, p < .01), and 80% (retention test and compared with pretest, p < .01). Sixty-nine (70%) respondents improved their pretest to retention test score by a mean of 2.4 points out of a total 10 points (median: 2 points; range: -5 to 7 points). Only 48% of pretest respondents correctly answered that PEP should not be administered immediately to anyone bitten by a healthy dog. However, 81% and 70% answered correctly on the posttest (p < .0001) and retention test (p = .002), respectively. Respondents demonstrated rabies epidemiology and PEP knowledge gain and ≥3-month knowledge retention after completing the online continuing education module.

Characteristics of immunized and un-immunized students, including non-medical exemptions, in Ontario, Canada: 2016-2017 school year.

BACKGROUND: Our objectives were: (1) to quantify and describe un-immunized students in Ontario, Canada and assess the extent to which these students have exemptions; and (2) to quantify and describe students with non-medical exemptions (NMEs), including what proportion have up-to-date immunizations. METHODS: We examined Ontario students 7 to 17 years-of-age in the 2016-2017 school year using information within a centralized immunization repository. We identified and described students with different immunization/exemption classifications by age, sex, school type, geography and area-level material deprivation using descriptive and multivariable logistic regression analyses. Finally, we assessed the immunization status of students with NMEs, by antigen. RESULTS: We found that students could be recorded as un-immunized with or without an NME, or be immunized with an NME. From a cohort of 1.65 million students, 2.9% of students had zero vaccine doses recorded, and of these 68% had no exemption of any kind. A total of 2.4% of students had an NME. Of these, 39% were un-immunized and 61% had received ≥1 vaccine. Among all students with NMEs, 19-48% had up-to-date immunizations, varying by antigen. Factors associated with increased odds of having a NME and being un-immunized included: attendance at private and 'other' schools, rural residence, and geography. Older age and greater area-level deprivation were associated with a reduced odds. CONCLUSIONS: Our assessment revealed that Ontario students with NMEs cannot be assumed to be un-immunized and at risk for all vaccine-preventable diseases. Conversely, not all un-immunized students had NMEs suggesting that future studies of un-immunized children in Ontario must consider additional factors beyond NME status alone. Other jurisdictions that use NME data to inform research and surveillance of vaccine hesitancy and risks for VPD outbreaks may wish to undertake a similar assessment to determine how well student NMEs correlate with student immunization status.
