Effectiveness of a multidisciplinary risk assessment and management programme-diabetes mellitus (RAMP-DM) on patient-reported outcomes

Outcomes of a risk assessment and management program using telecare consultation among patients with diabetes mellitus in general out-patient clinic: a hybrid effectiveness-implementation study protocol

Diabetes Mellitus (DM) is a chronic disease characterized by abnormally uncontrolled high blood glucose level. The Risk Assessment and Management Program (RAMP) in Hong Kong has been providing long-term face-to-face follow-up to DM patients in the government out-patient clinics since 2009. However, under the current outbreak of COVID-19, these face-to-face consultations were ceased over and over again to lower the risk of disease transmission. With the advancement in technology, the recent emergence of telecare has provided an alternative to replace the conventional consultations in the clinics. Its clinical effectiveness on DM patients has also been supported by numerous studies. Yet, there is only a paucity of literatures discussing the practicality of such implementation design in the real-world settings. This study aims at studying both the effectiveness and implementation outcomes of telecare in Hong Kong DM patients. It adopts a type 2 hybrid effectiveness-implementation design. It will be conducted in seven government out-patient clinics in Hong Kong. The subjects will be randomly assigned to an intervention group or a control group when they 1) are aged 18 or above, 2) have a confirmed diagnosis of diabetes, and 3) are having regular follow-up appointment in the clinic. Subjects in the intervention group will receive a 84-week Risk Assessment and Management Program (RAMP) in an alternate telecare and face-to-face consultations mode, while the control group will receive the same program but in usual face-to-face consultation mode. RE-AIM is employed as the implementation and effectiveness outcome evaluation framework. The primary outcome measure will be HbA1c. Data will be collected pre-intervention (T1), 42-week (T2), and 84-week (T3). The study will provide effectiveness-implementation assessment of telecare mode for DM patients in Hong Kong, as an alternative or in addition to conventional face-to-face consultations. It also aimed to provide insights for the future adoption in a broader health care setting.

Educational Interventions for Promoting Food Literacy and Patient Engagement in Preventing Complications of Type 2 Diabetes: A Systematic Review

The present review aims to map the current literature on educational interventions to promote food literacy in type 2 diabetes, with a particular focus on the concept of patient engagement. The systematic review was implemented on five databases with no restrictions on the publication year. The studies selected for the review were focused on patients with type 2 diabetes, ranging from 2003 to 2021 and published in 13 countries (44% USA). Thirty-three articles were analyzed. Twenty-seven articles targeted singular patients; fifteen articles conceptualized patient engagement as self-management. In seven articles, the provider is a multidisciplinary team. Twenty articles did not report a theoretical framework in the intervention development, and eleven did not use an intervention material. Twenty-six articles did not use a technology proxy. Outcome categories were narratively mapped into four areas: clinical, psychological, behavioral, and literacy. To date, most of the interventions are heterogeneous in the adopted methodology, measures, and outcomes considered. More attention should be given to the psychosocial characterization of patient engagement as well as the technological support. High-quality, randomized controlled trials and longitudinal studies are lacking and need to be conducted to verify the efficacy of these insights.

Outcomes in an Interdisciplinary Diabetes Clinic in Rural Primary Care

OBJECTIVE

The purpose of this study was to evaluate the effectiveness of an interdisciplinary diabetes team model of care in assisting patients to achieve improved glucose control in a primary care rural setting.

METHODS

A family medicine clinic at a rural university medical center developed an interdisciplinary diabetes team clinic composed of a certified diabetes educator/dietitian, a case manager, a pharmacist, nursing staff, a family medicine resident, a psychologist, and a board-certified family medicine attending physician. Patients were referred if their hemoglobin A1c (HbA1c) was ≥9% (75 mmol/mol); patients were seen for an initial consultation and for additional visits as needed.

RESULTS

A total of 94 patients attended an initial visit and at least 1 follow-up within 6 months. Mean age was 57 ± 13 years, and 54% were female. Median time from the initial intensive diabetes clinic visit to a follow-up visit was 2.8 months. There was a significant reduction in median HbA1c percentage from 10.25% (88.5 mmol/mol) ± 1.4% (range 73-104 mmol/mol) at the initial intensive diabetes clinic visit to 8.7% (72 mmol/mol) ± 1.8% (range 52-92 mmol/mol) at a 1- to 6-month follow-up (z = -7.161, P < 0.001) and a significant difference between baseline HbA1c (10.25% [88.5 mmol/mol] ± 1.4% [range 73-104 mmol/mol]) and latest HBA1c (1-18 months later) 8.4% (68 mmol/mol) ± 2.2% (range 44-92 mmol/mol; z = -7.022, P < 0.001). Overall, 86% of patients had a lower HbA1c at follow-up, and 33% had an HbA1c <8% (64 mmol/mol). There were no differences in patients' blood pressure, immunization rates, or lipid values between baseline and follow-up visits (P > 0.05).

CONCLUSIONS

An interdisciplinary team approach to glycemic control can achieve significant reductions in HbA1c in the rural primary care setting.

Risk factors of chronic kidney diseases in Chinese adults with type 2 diabetes

In this study we conducted a cross sectional study to comprehensively evaluated the risk factors of chronic kidney disease (CKD) in a large sample of Chinese adults under primary care for type 2 diabetes mellitus (T2DM). We investigated the risk factors associated with the prevalence of CKD in adults with T2DM, who were enrolled in the Risk Factor Assessment and Management Programme for Patients with Diabetes Mellitus (RAMP-DM) of Hong Kong from July 2014 to June 2017. We collected the individual data of 31,574 subjects, with mean age of 63.0 (±10.8) years and mean DM duration of 7.4 (±6.4) years. Of them 9,386 (29.7%) had CKD and 7,452 (23.6%) had micro- or macro-albuminuria. After adjustment for multiple demographic and lifestyle confounders, we identified several modifiable risk factors associated with higher rate of CKD: obesity (OR = 1.54), current smoking (OR = 1.33), higher systolic blood pressure (OR = 1.01), dyslipidemia (OR = 1.32 and 0.61 for triglycerides (TG) and high-density lipoprotein cholesterol (HDL-C)), hyperglycemia (OR = 1.11 for HbA1c), diabetic retinopathy (OR = 1.36 and 2.60 for non-sight and sight threatening retinopathy), and stroke (OR = 1.43). The risk factors of lower dialytic blood pressure and coronary heart disease were identified only in men, whereas peripheral arterial disease only in women. In conclusion, several modifiable and gender specific risk factors were significantly associated with higher prevalence of CKD in Chinese adults with T2DM. The high-risk populations identified in this study shall receive regular screening for renal functions to achieve better patient management in primary care settings.

Evaluation of the internal and external responsiveness of Short Form-12 Health Survey version 2 (SF-12v2) in patients with type 2 diabetes mellitus

PURPOSE

The evidence on the responsiveness of the Short Form-12 Health Survey version 2 (SF-12v2) in patients with type 2 diabetes mellitus (T2DM) is limited. The aim of this study was to examine both the internal and external responsiveness of the SF-12 measures in Chinese patients with T2DM.

METHODS

A prospective longitudinal observational study was conducted on 1443 T2DM patients managed in public primary care clinics between 2012 and 2013. These patients were surveyed at baseline and at 12 months using SF-12v2. The internal responsiveness was evaluated by linear mixed effect models. Meanwhile, the external responsiveness was tested by multiple linear regression models and receiver operating characteristic (ROC) curve analysis.

RESULTS

The internal responsiveness of the SF-12v2 to detect negative change was satisfactory among T2DM patients in worsened group, but only the general health domain of SF-12v2 could detect positive change among T2DM patients with improved group. For external responsiveness, the SF-12v2 detected a significant difference-in-difference between patients with worsened and stable/improved group, but not between patients with stable and improved group. The areas under the ROC curve for all domains and summary scales of the SF-12v2 were not statistically different from 0.7.

CONCLUSION

This study showed that the responsiveness of SF-12v2 might not achieve the standard. Despite the wide use of the SF-12v2, we would like to urge that both clinicians and researchers should use it with caution in longitudinal study.

Temporal trends in quality of primary care for patients with type 2 diabetes mellitus: A population-based retrospective cohort study after implementation of a quality improvement initiative

BACKGROUND

This study examined whether temporal trends exist in treatment of patients with type 2 diabetes (T2D) and quality of diabetes care after implementation of quality improvement initiative in primary care setting.

METHODS

We conducted a population-based retrospective cohort study of 202,284 patients with T2D who were routinely managed in primary care clinics. We examined the change over time and the variability between clinics in quality of care from Hospital Authority administrative data over a 5-year period (2009-2013) and used multilevel logistic regression to adjust for patient and clinic characteristics. Observational period was partitioned in 5 calendar years. Ten quality-of-care criteria were selected: adherence to 7 process of care criteria (HbA_1c test, renal function test, full lipid profile, urine protein analysis, retinal screening, lipid-lowering agent prescriptions among patients with hypercholesterolaemia, and angiotensin converting enzyme inhibitor/angiotensin receptor blocker prescriptions among patients with microalbuminuria) and 3 outcome of care criteria (HbA_1c  ≤ 7%, BP ≤ 130/80 mmHg, and LDL-C ≤ 2.6 mmol/L). Variability of standards between clinics was assessed by using intracluster correlation coefficients.

RESULTS

Characteristics of patients with T2D managed in primary care changed substantially during the observational period, with increasing age and usage of insulin and longer duration of diabetes but improved metabolic profiles (all P trend < .001). Performance rates of the 7 process and 3 clinical outcomes of care criteria increased remarkably over time (all P trend < .001). Variations in retinal screening delivery between clinics were considerable, albeit decreasing over time.

CONCLUSIONS

Coinciding with implementation of quality improvement initiative, quality of diabetes care improved significantly in the past 5 years, in part attributable to benefits of integrated multidisciplinary diabetes management.
