Effectiveness of the chronic care model for adults with type 2 diabetes in primary care: a systematic review and meta-analysis

Effectiveness of specialist involvement in case discussion conferences with primary healthcare providers on the management of type 2 diabetes patients: a study protocol for a cluster randomized controlled trial

BACKGROUND

In supporting primary healthcare in delivering high-quality care for individuals with type 2 diabetes mellitus (T2DM), previous research emphasized strategies to facilitate communication and collaboration between primary healthcare providers and hospitals. This study aims to evaluate the effectiveness of case discussion conferences between specialists from hospitals and primary healthcare providers in China on the optimization of diabetes management and the improvement of patient health outcomes.

METHODS

This study will be a parallel cluster randomized controlled trial in which primary healthcare institutions in Shouguang city and Shangsi County will be randomly allocated to the intervention and control groups. The intervention will involve regular case discussion conferences where attendants will meet to discuss complex cases with patients diagnosed with type 2 diabetes mellitus, exchange experiences, and seek and provide expert advice. Family doctor teams from primary healthcare institutions and specialists from secondary or tertiary hospitals will engage in these conferences. Data will be collected at baseline and at the 6- and 12-month follow-ups. The primary clinical outcome measures will focus on the changes in the HbA1c and FBG levels of patients under management. The secondary outcomes will include other physiological indicators, such as blood pressure, BMI, and cholesterol. The evaluation will extend to changes in the capabilities and behaviors of primary healthcare providers. Furthermore, the feasibility and adherence of this intervention will be thoroughly assessed.

DISCUSSION

This study is designed to generate robust evidence on the effectiveness of case discussion conferences, an interprofessional collaboration strategy, in enhancing diabetes care delivery in primary healthcare, with the ultimate goal of improving patient health outcomes.

Are integrated care models associated with improved drug safety in Swiss primary care? an observational analysis using healthcare claims data

BACKGROUND

Integrated care models (ICMs) might be an effective strategy to improve patients' quality of care. The aim of this study was to compare different ICMs such as family-doctor models, and a standard care model (SCM) regarding patients' drug safety in Swiss primary care.

METHODS

We performed an observational study using health insurance claims data from patients who were continuously enrolled in an ICM or in a SCM between 2020 and 2021. ICMs included family-doctor model (FDM), family-doctor model light (FDM-light) and the telemedicine model (TM). Drug safety was assessed by the prescription of potentially inappropriate proton pump-inhibitors (PIPPI), opioids (PIO), medications (PIM), and polypharmacy. Propensity-score-weighted multiple logistic regression models were used to examine the association between different types of ICMs and drug safety.

RESULTS

Patients in FDM had significantly lower odds of receiving PIPPI (OR, 0.86; CI 95%, 0.83-0.89), PIO (OR, 0.81; CI 95%, 0.76-0.85), PIM (OR, 0.94; CI 95%, 0.91-0.97), and polypharmacy (OR, 0.94; CI 95%, 0.91-0.97) compared to patients in SCM. Potentially inappropriate prescribing was also lower in patients in TM and partly in FDM-light than in SCM. Persons enrolled in FDM were less likely to receive PIM (OR, 0.93; CI 95%, 0.89-0.97) and polypharmacy (OR, 0.94; CI 95%, 0.90-0.99) than those in FDM-light, whereas the odds of receiving PIPPI and polypharmacy were higher in FDM than in TM.

CONCLUSION

ICMs were significantly associated with higher drug safety compared to SCM for most outcomes. Findings suggest that patients may benefit most from ICMs with a high degree of coordination or gatekeeping. ICM may represent an effective approach to improve patients' drug safety and, thus, to reduce the risk of adverse events.

A retrospective cohort study of a community-based primary care program's effects on pharmacotherapy quality in low-income Peruvians with type 2 diabetes and hypertension

Little is known about the effects of the Chronic Care Model (CCM) and community health workers (CHWs) on pharmacotherapy of type 2 diabetes and hypertension in resource-poor settings. This retrospective cohort implementation study evaluated the effects of a community-based program consisting of CCM, CHWs, guidelines-based treatment protocols, and inexpensive freely accessible medications on type 2 diabetes and hypertension pharmacotherapy quality. A door-to-door household survey identified 856 adults 35 years of age and older living in a low-income Peruvian community, of whom 83% participated in screening for diabetes and hypertension. Patients with confirmed type 2 diabetes and/or hypertension participated in the program's weekly to monthly visits for < = 27 months. The program was implemented as two care periods employed sequentially. During home care, CHWs made weekly home visits and a physician made treatment decisions remotely. During subsequent clinic care, a physician attended patients in a centralized clinic. The study compared the effects of program (pre- versus post-) (N = 262 observations), and home versus clinic care periods (N = 211 observations) on standards of treatment with hypoglycemic and antihypertensive agents, angiotensin converting enzyme inhibitors, and low-dose aspirin. During the program, 80% and 50% achieved hypoglycemic and antihypertensive standards, respectively, compared to 35% and 8% prior to the program, RRs 2.29 (1.72-3.04, p <0.001) and 6.64 (3.17-13.9, p<0.001). Achievement of treatment standards was not improved by clinic compared to home care (RRs 1.0 +/- 0.08). In both care periods, longer retention in care (>50% of allowable time) was associated with achievement of all treatment standards. 85% compared to 56% achieved the hypoglycemic treatment standard with longer and shorter retention, respectively, RR 1.52 (1.13-2.06, p<0.001); 56% compared to 27% achieved the antihypertensive standard, RR 2.11 (1.29-3.45, p<0.001). In a dose-dependent manner, the community-based program was associated with improved guidelines-based pharmacotherapy of type 2 diabetes and hypertension.

Using a collaborative learning health system approach to improve disease activity outcomes in children with juvenile idiopathic arthritis in the Pediatric Rheumatology Care and Outcomes Improvement Network

Introduction

The Pediatric Rheumatology Care and Outcomes Improvement Network (PR-COIN) is a North American learning health network focused on improving outcomes of children with juvenile idiopathic arthritis (JIA). JIA is a chronic autoimmune disease that can lead to morbidity related to persistent joint and ocular inflammation. PR-COIN has a shared patient registry that tracks twenty quality measures including ten outcome measures of which six are related to disease activity. The network's global aim, set in 2021, was to increase the percent of patients with oligoarticular or polyarticular JIA that had an inactive or low disease activity state from 76% to 80% by the end of 2023.

Methods

Twenty-three hospitals participate in PR-COIN, with over 7,200 active patients with JIA. The disease activity outcome measures include active joint count, physician global assessment of disease activity, and measures related to validated composite disease activity scoring systems including inactive or low disease activity by the 10-joint clinical Juvenile Arthritis Disease Activity Score (cJADAS10), inactive or low disease activity by cJADAS10 at 6 months post-diagnosis, mean cJADAS10 score, and the American College of Rheumatology (ACR) provisional criteria for clinical inactive disease. Data is collated to measure network performance, which is displayed on run and control charts. Network-wide interventions have included pre-visit planning, shared decision making, self-management support, population health management, and utilizing a Treat to Target approach to care.

Results

Five outcome measures related to disease activity have demonstrated significant improvement over time. The percent of patients with inactive or low disease activity by cJADAS10 surpassed our goal with current network performance at 81%. Clinical inactive disease by ACR provisional criteria improved from 46% to 60%. The mean cJADAS10 score decreased from 4.3 to 2.6, and the mean active joint count declined from 1.5 to 0.7. Mean physician global assessment of disease activity significantly improved from 1 to 0.6.

Conclusions

PR-COIN has shown significant improvement in disease activity metrics for patients with JIA. The network will continue to work on both site-specific and collaborative efforts to improve outcomes for children with JIA with attention to health equity, severity adjustment, and data quality.

Interdisciplinary Diagnosis and Management of Patients With Interstitial Lung Disease and Connective Tissue Disease

A diagnosis of interstitial lung diseases (ILD) can be challenging, and the identification of an associated connective tissue disease (CTD) is crucial to estimate prognosis and to establish the optimal treatment approach. Diagnostic delay, limited expertise, and fragmented care are barriers that impede the delivery of comprehensive health care for patients with rare, complex, and multiorgan diseases such as CTD and ILD. In this article, we present our perspective on the interdisciplinary diagnosis and interprofessional treatment of patients with ILD and suspected CTD or CTD at risk of ILD. We outline the structure of our service, delineating the roles and responsibilities of the team members. Additionally, we provide an overview of our patient population, including diagnostic approaches and specific treatments, and illustrate a patient case. Furthermore, we focus on specific benefits and challenges of joint interdisciplinary and interprofessional patient consultations. The importance of rheumatology and pulmonology assessments in specific patient populations is emphasized. Finally, we explore future directions and discuss potential strategies to improve care delivery for patients with CTD-associated ILD.

Improving outcomes of type 2 diabetes mellitus patients in primary care with Chronic Care Model: A narrative review

Designed and implemented over two decades ago, the Chronic Care Model is a well-established chronic disease management framework that has steered several healthcare systems in successfully improving the clinical outcomes of patients with type 2 diabetes mellitus. Research evidence cements the role of the Chronic Care Model (with its six key elements of organization of healthcare delivery system, self-management support, decision support, delivery system design, clinical information systems, and community resources and policies) as an integrated framework to revamp the type 2 diabetes mellitus-related clinical practice and care that betters the patient care and clinical outcomes. The current review is an evidence-lit summary of importance of use of Chronic Care Model in primary care and their impact on clinical outcomes for patients afflicted with one of the most debilitating metabolic diseases, type 2 diabetes mellitus.

Uncovering Risks Associated with Smoking Types and Intensities in Esophageal Cancer within High-Prevalence Regions in Africa: A Comprehensive Meta-analysis

Tobacco is usually cited among the well-known risk factors of esophageal cancer; nevertheless, the extent of the contribution of the type of smoking and its intensity to the disease has not been comprehensively elucidated in Africa. We searched MEDLINE/PubMed, Excerpta Medica Database, Web of Science, Scopus, Cochrane Library, and African Journals Online studies published before September 2023. The quality of the studies was assessed using the Newcastle-Ottawa scale, and the funnel plot was used for assessing potential publication bias. Meta-analyses were conducted to estimate summary effects using random-effects models. This study included 22,319 participants from 27 studies. The results strongly indicate a significant association between tobacco use and a higher risk of esophageal cancer. The risk of esophageal cancer is notably higher among pipe smokers [OR = 4.68; 95% confidence interval (CI), 3.38-6.48], followed by hand-rolled cigarette smokers (OR = 3.79; 95% CI, 2.68-5.35), in comparison with those who smoked commercially manufactured cigarettes (OR = 2.46; 95% CI, 1.69-3.60). Our findings also showed that the risk of esophageal cancer is highest in people smoking >183 packs per year (OR = 5.47; 95% CI, 3.93-7.62), followed by those smoking 93 to 183 packs per year (OR = 3.90; 95% CI, 3.13-4.86), in comparison with those smoking ≤92 packs per year (OR = 2.90; 95% CI, 2.19-3.84). Our findings strongly show that among the different types of tobacco use in Africa, pipe and hand-roller smokers face a higher risk of esophageal cancer.

Integrated patient-centred care for type 2 diabetes in Singapore Primary Care Networks: a mixed-methods study

OBJECTIVE

Patients with type 2 diabetes require patient-centred care as guided by the Chronic Care Model (CCM). Many diabetes patients in Singapore are managed by the Primary Care Networks (PCNs) which organised healthcare professionals (HCPs) comprising general practitioners, nurses and care coordinators into teams to provide diabetes care. Little is known about how the PCNs deliver care to people with type 2 diabetes. This study evaluated the consistency of diabetes care delivery in the PCNs with the CCM.

DESIGN

This was a mixed-method study. The Assessment of Chronic Illness Care (ACIC version 3.5) survey was self-administered by the HCPs in the quantitative study (ACIC scores range 0-11, the latter indicating care delivery most consistent with CCM). Descriptive statistics were obtained, and linear mixed-effects regression model was used to test for association between independent variables and ACIC total scores. The qualitative study comprised semi-structured focus group discussions and used thematic analysis.

SETTING

The study was conducted on virtual platforms involving the PCNs.

PARTICIPANTS

179 HCPs for quantitative study and 65 HCPs for qualitative study.

RESULTS

Integrated analysis of quantitative and qualitative results found that there was support for diabetes care consistent with the CCM in the PCNs. The mean ACIC total score was 5.62 (SD 1.93). The mean element scores ranged from 6.69 (SD 2.18) (Health System Organisation) to 4.91 (SD 2.37) (Community Linkages). The qualitative themes described how the PCNs provided much needed diabetes services, their characteristics such as continuity of care, patient-centred care; collaborating with community partners, financial aspects of care, enablers for and challenges in performing care, and areas for enhancement.

CONCLUSION

This mixed-methods study informs that diabetes care delivery in the Singapore PCNs is consistent with the CCM. Future research should consider using independent observers in the quantitative study and collecting objective data such as patient outcomes.

Role of community-based health clubs in promoting patients' health education for diabetes self-care management: an interventional qualitative study in a Ugandan urban setting

BACKGROUND

Self-care management support is a core component of the Chronic Care Model that emphasises the need for empowering and preparing patients to manage their healthcare. In diabetes mellitus (DM) management, health education towards self-care empowers patients to make day-to-day decisions on their own disease and live with a healthy lifestyle. Although several strategies have been undertaken to improve the management of DM in Uganda, little has been done to empower patients to manage their own health. Community-based health clubs have been suggested as a novel way of improving diabetes management especially in settings with uneven distribution of healthcare facilities and inaccessibility to healthcare services that limit patients' awareness of the disease and self-care management. This interventional study was aimed at exploring the role of community-based health clubs in promoting patients' health education for diabetes self-care management.

METHODS

A cross-sectional qualitative study was conducted among 20 participants using focus group discussions with each having six to eight members. Only patients with diabetes who seek routine diabetes healthcare services at Wakiso Health Centre IV and had participated in the 8-week community-based health clubs' health education sessions were recruited for the study. The audio-recordings were transcribed verbatim and translated into English; thematic data analysis was conducted to generate codes and themes. Similar codes were merged and a group consensus was reached on coding discrepancies.

RESULTS

Three major themes on the role of health clubs in promoting patients' health education were merged from the study. These include promoting sharing of experiences among patients, improving awareness of healthy self-care practices and offering sufficient patient-health worker interaction time.

CONCLUSIONS

This is the first publication reporting on the role of community-based health clubs in promoting patients' health education towards diabetes self-care management in Uganda. The ability to share experiences among patients, improve patients' awareness on healthy living practices and the increased health worker-patient interaction time contribute heavily to the capacity-building for self-care among patients.

Patient perspectives of diabetes care in primary care networks in Singapore: a mixed-methods study

BACKGROUND

Type 2 diabetes (T2D) remains an important chronic condition worldwide requiring integrated patient-centred care as advocated by the Chronic Care Model (CCM). The Primary Care Networks (PCNs) in Singapore organise general practitioners (GPs) with nurses and care coordinators to deliver team-based care for patients with chronic conditions. This study examined the quality of care in the PCNs as defined by the CCM from the patients' perspective.

METHODS

This study followed a cross-sectional convergent mixed-method design with T2D patients across three PCN types (GP-led, Group, and Cluster). The Patient Assessment of Chronic Illness Care (PACIC, range 1-5) was completed by a convenience sample of 343 patients. Multivariate linear regression was performed to estimate the associations between patient and service characteristics and PACIC summary score. Twenty-four participants were purposively recruited for interviews on the experienced care until thematic saturation was reached. Quantitative and qualitative data were collected concurrently and independently. Integration occurred during study design and data analysis using the CCM as guidance. Quantitative and qualitative results were compared side-by-side in a joint comparison table to develop key concepts supported by themes, subthemes, and patients' quotes.

RESULTS

The PACIC mean summary score of 3.21 for 343 patients evidenced that some have received CCM consistent care in the PCNs. Being younger and spending more time with the GP were associated with higher PACIC summary scores. PACIC summary scores did not differ across PCN types. The 24 patients interviewed in the qualitative study reported receiving team-based care, nurse services, good continuity of care, as well as patient-centred care, convenient access, and affordable care. Key concepts showed that integrated care consistent with the CCM was sometimes received by patients in the PCNs. Patient activation, delivery system design/decision support, goal setting/tailoring, and problem-solving/contextual counselling were sometimes received by patients, while follow-up/coordination was generally not received.

CONCLUSIONS

Patients with T2D from the Singapore Primary Care Networks received integrated care consistent with the Chronic Care Model, particularly in patient activation, delivery system design/decision support, goal setting/tailoring, and problem-solving/contextual counselling. Follow-up/coordination needed improvement to ensure higher quality of diabetes care.

Association between initial continuity of care status and diabetes-related health outcomes in older patients with type 2 diabetes mellitus: A nationwide retrospective cohort study in South Korea

BACKGROUND AND AIM

Timely and continuous care is necessary for patients with diabetes to prevent hospitalization and complications. This study investigated the association between initial Continuity of Care Index (COCI) status after diagnosis of type 2 diabetes mellitus (T2DM) and short- and long-term diabetes-related health outcomes.

METHODS

It targeted elderly patients aged 60 years and above diagnosed with T2DM and used the National Health Insurance Service Senior cohort data from 2008 to 2019. The outcome measures were diabetic avoidable hospitalization and diabetic complication incidence for a five-year period. The main independent variable was the first-year COCI status after T2DM diagnosis. Survival analyses were performed using the Cox proportional hazards model.

RESULTS

Participants with a good COCI status within the first year of being diagnosed with T2DM experienced a reduced risk of diabetes-induced avoidable hospitalization (five years: Hazard ratio (HR) 0.39, 95 % Confidence interval (CI) 0.27-0.57; overall period: HR 0.56, 95 % CI 0.43-0.72) and diabetic complications (five years: HR 0.74, 95 % CI 0.68-0.80; overall period: HR 0.77, 95 % CI 0.71-0.82).

CONCLUSIONS

In the short- and long-term, there is a need for early management and improved healthcare accessibility of diabetes to prevent diabetes-avoidable hospitalization and diabetes-related complications.

A multicomponent health care intervention is associated with improved glycaemic control in subjects with poorly controlled type 2 diabetes compared with routine care: The INTEGRA study

AIM

The INTEGRA study evaluated whether a specially designed multicomponent health care intervention improved glycaemic control in subjects with poorly controlled type 2 diabetes compared with standard of care practice.

RESEARCH DESIGN AND METHODS

Pragmatic study in subjects from primary care centres with type 2 diabetes and glycated haemoglobin (HbA1c) >9% (75 mmol/mol). The multifaceted intervention (N = 225 subjects) included a diabetes-focused visit encouraging therapeutic intensification by health care professionals. Retrospective data from matched controls (N = 675) were obtained from electronic medical records of a primary care database. The primary outcome was to compare the change in HbA1c values between the groups at 12 months of follow-up.

RESULTS

The mean HbA1c decreased substantially in both groups after 3 months, and the mean reduction was significantly greater in the intervention group than in the usual care group after 12 months [mean difference -0.66% (-7 mmol/mol), 95% CI -0.4, -1.0; p < .001]. A larger percentage of participants in the intervention group achieved HbA1c <7% and <8% goals (15.5% vs. 5.3% and 29.3% vs. 13.5%, respectively; p < .001). The improvement in HbA1c levels was sustained throughout the study only in the intervention arm. Glucose-lowering therapy was more frequently intensified in patients in the intervention group at the initial and final time points of the study (between 0-3 and 6-12 months; p < .001), with a significant increase in the number of patients prescribed ≥2 antidiabetic therapies (p < .001).

CONCLUSIONS

A multifaceted intervention oriented at reducing therapeutic inertia by primary care physicians was associated with greater improvement in glycaemic control compared with patients treated as per usual care.

Effectiveness of integrated chronic care models for cardiometabolic multimorbidity in sub-Saharan Africa: a systematic review and meta-analysis

OBJECTIVES

This review aimed at identifying the elements of integrated care models for cardiometabolic multimorbidity in sub-Saharan Africa (SSA) and their effects on clinical or mental health outcomes including systolic blood pressure (SBP), blood sugar, depression scores and other patient-reported outcomes such as quality of life and medication adherence.

DESIGN

Systematic review and meta-analysis using the Grading of Recommendation, Assessment, Development and Evaluation (GRADE) approach.

DATA SOURCES

We systematically searched PubMed, Embase, Scopus, Web of Science, Global Health CINAHL, African Journals Online, Informit, PsycINFO, ClinicalTrials.gov, Pan African Clinical Trials Registry and grey literature from OpenSIGLE for studies published between 1999 and 2022.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

We included randomised controlled trial studies featuring integrated care models with two or more elements of Wagner's chronic care model.

DATA EXTRACTION AND SYNTHESIS

Two independent reviewers used standardised methods to search and screen included studies. Publication bias was assessed using the Doi plot and Luis Furuya Kanamori Index. Meta-analysis was conducted using random effects models.

RESULTS

In all, we included 10 randomised controlled trials from 11 publications with 4864 participants from six SSA countries (South Africa, Kenya, Nigeria, Eswatini, Ghana and Uganda). The overall quality of evidence based on GRADE criteria was moderate. A random-effects meta-analysis of six studies involving 1754 participants shows that integrated compared with standard care conferred a moderately lower mean SBP (mean difference=-4.85 mm Hg, 95% CI -7.37 to -2.34) for people with cardiometabolic multimorbidity; Hedges' g effect size (g=-0.25, (-0.39 to -0.11). However, integrated care compared with usual care showed mixed results for glycated haemoglobin, depression, medication adherence and quality of life.

CONCLUSION

Integrated care improved SBP among patients living with cardiometabolic multimorbidity in SSA. More studies on integrated care are required to improve the evidence pool on chronic care models for multimorbidity in SSA. These include implementation studies and cost-effectiveness studies.
