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

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.
