Quality of type 2 diabetes management in general practice is associated with involvement of general practice nurses

Systematic review of the effectiveness of nurse-led care in reducing glycated haemoglobin in adults with Type 1 or 2 diabetes

BACKGROUND

Type 1 and 2 diabetes care, especially within primary health-care settings, has traditionally involved doctor-led clinics. However, with increasing chronic disease burden, there is scope for nurses to expand their role in assisting diabetes self-management.

AIMS

This study aimed to determine the effectiveness of nurse-led care in reducing glycated haemoglobin in adults with Type 1 or 2 diabetes.

METHODS

Methodology from the Joanna Briggs Institute Method for Systematic Review Research and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed, including identifying publications, assessing study quality, summarizing evidence and interpreting findings. The search strategy involved using the Medical Subject Headings and keyword variations when searching MEDLINE (Ovid), Scopus, PubMed and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases. Inclusion criteria were samples with Type 1 or 2 diabetes, mean age of ≥18 years, English language studies and publication date of January 2011-December 2021.

RESULTS

Overall, 34 articles from 16 countries met inclusion criteria. Though not always clinically significant, results indicated that nurse-led care had beneficial impacts on glycated haemoglobin values, with reductions from 0.03% to 2.0%. This was evident when nurses received formal training, used treatment algorithms, had limited medical support, utilized technology and offered defined culturally sensitive and appropriate diabetes care.

CONCLUSIONS

Findings support nurse-led Type 1 and 2 diabetes care. Although further research is required, changes may necessitate increased recognition of nurse-led care and funding. Nurse-led care models should differ according to health-care settings.

Needs assessment of diabetic foot services in Zimbabwe

INTRODUCTION

Due to the increasing incidence of diabetes in Zimbabwe, complications such as diabetic foot (DF) are anticipated. Establishing local gaps and needs in DF healthcare is paramount for tailoring management strategies.

AIMS

To determine the status of DF services in the healthcare system and explore awareness of DF management and practices among registered general nurses (RGNs) in Zimbabwe.

METHODS

A mixed-methods approach was applied. Thirty-one RGNs from 16 public health facilities in Harare, Zimbabwe attending a DF workshop were administered with a cross-sectional survey instrument and a semi-structured questionnaire. Data collected included presence/absence of DF services and podiatrists in healthcare facilities, healthcare system approaches in DF care and availability of DF training/education programs for RGNs. Analysis was performed using Stata and Nvivo software.

RESULTS

No respondents reported availability of podiatrists. Only 1 (3%) of RGNs reported DF screening in primary care. Sixty percent (18) did not know or had never screened for DF. The RGNs reported inadequate DF educational programs/modules in primary care settings.

CONCLUSION

This data highlights a need to improve DF education for RGNs at the frontline of managing PLWD. Understanding the needs for DF services may guide interventions to improve education and awareness programs that are appropriately tailored to local constraints in the health system. The non-communicable diseases director is encouraged to develop DF educational programmes for frontline health care workers.

Primary Care Variation in Rates of Unplanned Hospitalizations, Functional Ability, and Quality of Life of Older People

PURPOSE

To investigate variability in older people's outcomes according to general practitioner (GP) and practice characteristics in New Zealand and the Netherlands.

METHODS

We used data from 2 primary care-based, cluster-randomized, controlled trials to separately fit mixed models of unplanned admission rates, functional ability, and quality of life (QOL) and examine variation according to GP- and practice-level characteristics after adjusting for participant-level characteristics. For the New Zealand sample (n = 3,755 aged 75+ years in 60 practices), we modeled 36-month unplanned admission rates, Nottingham Extended Activities of Daily Living (NEADL) scale, and QOL domain ratings from the brief version of the World Health Organization Quality of Life assessment tool. For the Netherlands sample (n = 3,141 aged 75+ years in 59 practices), we modeled 12-month unplanned admission rates, Groningen Activity Restriction Scale scores, and EuroQOL 5 dimensions (EQ-5D) summary index.

RESULTS

None of the GP or practice characteristics were significantly associated with rates of unplanned admissions in the New Zealand sample, but we found greater rates of admission in larger practices (incidence rate ratio [IRR], 1.45; 95% CI, 1.15-1.81) and practices staffed with a practice nurse (IRR, 1.74; 95% CI, 1.20-2.52) in the Netherlands sample. In both samples, differences were consistently small where there were significant associations with function (range, -0.26 to 0.19 NEADL points in the New Zealand sample; no associations in the Netherlands sample) and QOL (range, -1.64 to 0.97 QOL points in New Zealand; -0.01 EQ-5D points in the Netherlands).

CONCLUSIONS

In the absence of substantial differences in older people's function and QOL, it remains unclear whether intriguing GP- or practice-related variations in admission rates represent low- or high-quality practice.

The Role of Physician and Practice Characteristics in the Quality of Diabetes Management in Primary Care: Systematic Review and Meta-analysis

BACKGROUND

Despite evidence-based guidelines, high-quality diabetes care is not always achieved. Identifying factors associated with the quality of management in primary care may inform service improvements, facilitating the tailoring of quality improvement interventions to practice needs and resources.

METHODS

We searched MEDLINE, EMBASE, CINAHL and Web of Science from January 1990 to March 2019. Eligible studies were cohort studies, cross-sectional studies and randomised controlled trials (baseline data) conducted among adults with diabetes, which examined the relationship between any physician and/or practice factors and any objective measure(s) of quality. Studies which examined patient factors only were ineligible. Where possible, data were pooled using random-effects meta-analysis.

RESULTS

In total, 82 studies were included. The range of individual quality measures and the construction of composite measures varied considerably. Female physicians compared with males ((odds ratio (OR) = 1.07, 95% CI: 1.04, 1.10), 8 studies), physicians with higher diabetes volume compared with lower volume (OR = 1.24, 95% CI: 1.05-1.47, 4 studies) and practices with Electronic Health Records (EHR) versus practices without (OR = 1.43, 95% CI: 1.11-1.84, 4 studies) were associated with a higher quality of care. There was no association between physician experience, practice location and type of practice and quality. Based on the narrative synthesis, increasing physician age and higher practice socio-economic deprivation may be associated with lower quality of care.

DISCUSSION

Identification of physician- and practice-level factors associated with the quality of care (female gender, younger age, physician-level diabetes volume, practice deprivation and EHR use) may explain differences across practices and physicians, provide potential targets for quality improvement interventions and indicate which practices need specific supports to deliver improvements in diabetes care.

The roles of healthcare professionals in diabetes care: a qualitative study in Norwegian general practice

Objective: To explore the experiences of general practitioners (GPs), nurses and medical secretaries in providing multi-professional diabetes care and their perceptions of professional roles.Design, setting and subjects: Semi-structured interviews were conducted with six GPs, three nurses and two medical secretaries from five purposively sampled diabetes teams. Interviews were analysed thematically.Main outcome measures: Healthcare professionals' (HCPs') experiences of multi-professional diabetes care in general practice.Results: The involvement of nurses and medical secretaries (collaborating health care professionals) was mainly motivated by GPs' time pressure and their perception of diabetes care as easy to standardize. GPs reported that diabetes care had become more structured and continuous after the involvement of collaborating health care professionals (cHCPs). cHCPs defined their role differently from GPs, emphasizing that their approach included acknowledging patients' need for diabetes education, listening to their stories and meeting their need for emotional support. GPs appeared less involved in patients' emotional concerns and more focused on the biomedical aspects of illness. There was little emphasis on teamwork among GPs and cHCPs, and none of the practices used care plans to involve patients in decisions or unify treatment among professionals. Participants stated that institutional structures including a discriminatory remuneration system, lack of role descriptions and missing procedures for collaborative approaches were an obstacle to MPC.Conclusions: cHCPs worked independently under delegated leadership of the GPs. Although cHCPs had a complementary role, HCPs in general practice may not take full advantage of the potential of sharing patient responsibility and learning with, from and about each other. Contextual barriers for team-based care approaches should be addressed in future research.KEY POINTSIt has been suggested that multi-professional approaches improve quality of care in people with long-term conditions.In this study, nurses and medical secretaries perceived to have a complementary role to general practitioners (GPs) in diabetes care, focusing on patient education, building trusting relationships and providing patients with emotional support.As multi-professional collaboration was minimal, GPs, nurses and medical secretaries in the included practices may not take full advantage of the potential of sharing care responsibility and learning with, from and about each other.

Associations between degrees of task delegation and adherence to COPD guidelines on spirometry testing in general practice - a national cross-sectional study

Background

The healthcare systems in the western world have in recent years faced major challenges caused by demographic changes and altered patterns of diseases as well as political decisions influencing the organisation of healthcare provisions. General practitioners are encouraged to delegate more clinical tasks to their staff in order to respond to the changing circumstances. Nevertheless, the degree of task delegation varies substantially between general practices, and how these different degrees affect the quality of care for the patients is currently not known. Using chronic obstructive pulmonary disease (COPD) as our case scenario, the aim of the study was to investigate associations between degrees of task delegation in general practice and spirometry testing as a measure of quality of care.

Methods

We carried out a cross-sectional study comprising all general practices in Denmark and patients suffering from chronic obstructive pulmonary disease. General practitioners (GPs) were invited to participate in a survey investigating degrees of task delegation in their clinics. Data were linked to national registers on spirometry testing among patients with COPD. We investigated associations using multilevel mixed-effects logit models and adjusted for practice and patient characteristics.

Results

GPs from 895 practices with staff managing COPD-related tasks responded, and 61,223 COPD patients were linked to these practices. Hereof, 24,685 (40.3%) had a spirometry performed within a year. Patients had a statistically significant higher odds ratio (OR) of having an annual spirometry performed in practices with medium or maximal degrees of task delegation compared to practices with a minimal degree (OR = 1.27 and OR = 1.33, respectively).

Conclusion

Delegating more complex tasks to practice staff implies that COPD-patients are more likely to be treated according to evidence-based recommendations on spirometry testing.

The clinical effectiveness of nursing models of diabetes care: A synthesis of the evidence

OBJECTIVES

To determine the clinical effectiveness (glycemic control, other biological measures, cost-effectiveness and patient satisfaction) of primary care nurse-led interventions for diabetes.

DESIGN

A systematic review following methods described for complex interventions and using PRISMA guidelines for reporting was undertaken. Nurse-led care for diabetes can be regarded as a complex intervention requiring the measurement of more than one outcome and for this reason we chose a range of outcomes clinical (symptoms), patient-centred (experiences) and organisational (cost-effectiveness).

DATA SOURCES

An extensive literature search using MEDLINE (PubMed) EMBASE, and CINAHL was conducted.

REVIEW METHODS

Primary studies with adults in primary care with both quantitative (comparison with physician-led care and cost-effectiveness) and qualitative (patient experiences of nurse-led care) methodologies from 2003 until June 2018. All studies were appraised using the Cochrane Collaboration's tool for assessing risk of bias. The appraisal involved evaluation of the degree of risk of bias in selection, performance, detection, attrition and reporting. Because of the complexity of multiple outcomes (quantitative and qualitative) a narrative synthesis was undertaken.

RESULTS

The search generated 18 published studies that met our eligibility criteria. Three randomized controlled trials and one historical control trial found statistically significant differences in glycemic levels in favour of the nurse-led interventions. Two cluster randomized trials, two randomized pragmatic trials and two randomized controlled trials found no differences between groups. The three open-label studies found statistically significant improvements in HbA1c levels. The audit identified that more patients had lower HbA1c levels after the initiation of a nurse-led intervention. Three randomized controlled trials found significant improvements in biological outcomes and one did not. The four studies measuring cost-effectiveness found the nurse-led intervention was associated with less costs. Four studies examined patient satisfaction with nurse-led care and found this was very good.

CONCLUSION

This review which incorporated a broad range of studies to capture the complexity of nurse-led interventions has identified that there is evolving evidence that nurse-led interventions for community treatment of diabetes may be more clinically effective than usual physician-led care.

Assessing the influence of health systems on Type 2 Diabetes Mellitus awareness, treatment, adherence, and control: A systematic review

BACKGROUND

Type 2 Diabetes Mellitus (T2DM) is reported to affect one in 11 adults worldwide, with over 80% of T2DM patients residing in low-to-middle-income countries. Health systems play an integral role in responding to this increasing global prevalence, and are key to ensuring effective diabetes management. We conducted a systematic review to examine the health system-level factors influencing T2DM awareness, treatment, adherence, and control.

METHODS AND FINDINGS

A protocol for this study was published on the PROSPERO international prospective register of systematic reviews (PROSPERO 2016: CRD42016048185). Studies included in this review reported the effects of health systems factors, interventions, policies, or programmes on T2DM control, awareness, treatment, and adherence. The following databases were searched on 22 February 2017: Medline, Embase, Global health, LILACS, Africa-Wide, IMSEAR, IMEMR, and WPRIM. There were no restrictions on date, language, or study designs. Two reviewers independently screened studies for eligibility, extracted the data, and screened for risk of bias. Thereafter, we performed a narrative synthesis. A meta-analysis was not conducted due to methodological heterogeneity across different aspects of included studies. 93 studies were included for qualitative synthesis; 7 were conducted in LMICs. Through this review, we found two key health system barriers to effective T2DM care and management: financial constraints faced by the patient and limited access to health services and medication. We also found three health system factors that facilitate effective T2DM care and management: the use of innovative care models, increased pharmacist involvement in care delivery, and education programmes led by healthcare professionals.

CONCLUSIONS

This review points to the importance of reducing, or possibly eliminating, out-of-pocket costs for diabetes medication and self-monitoring supplies. It also points to the potential of adopting more innovative and integrated models of care, and the value of task-sharing of care with pharmacists. More studies which identify the effect of health system arrangements on various outcomes, particularly awareness, are needed.

Conclusiones: por medio de la Teoría de la Atención Burocrática es posible describir la práctica del cuidado de enfermería en personas con diabetes mellitus tipo 2. Enfermería debe considerar los factores propios a la burocracia de toda organización, especialmente al momento de gestionar el cuidado en este tipo de pacientes.

How can point-of-care HbA1c testing be integrated into UK primary care consultations? - A feasibility study

AIMS

Point-of-care (POC) HbA1c testing gives a rapid result, allowing testing and treatment decisions to take place in a single appointment. Trials of POC testing have not been shown to improve HbA1c, possibly because of how testing was implemented. This study aimed to identify key components of POC HbA1c testing and determine strategies to optimise implementation in UK primary care.

METHODS

This cohort feasibility study recruited thirty patients with type 2 diabetes and HbA1c>7.5% (58mmol/mol) into three primary care clinics. Patients' clinical care included two POC HbA1c tests over six months. Data were collected on appointment duration, clinical decisions, technical performance and patient behaviour.

RESULTS

Fifty-three POC HbA1c consultations took place during the study; clinical decisions were made in 30 consultations. Five POC consultations with a family doctor lasted on average 11min and 48 consultations with nurses took on average 24min. Five POC study visits did not take place in one clinic. POC results were uploaded to hospital records from two clinics. In total, sixty-three POC tests were performed, and there were 11 cartridge failures. No changes in HbA1c or patient behaviour were observed.

CONCLUSIONS

HbA1c measurement with POC devices can be effectively implemented in primary care. This work has identified when these technologies might work best, as well as potential challenges. The findings can be used to inform the design of a pragmatic trial to implement POC HbA1c testing.

Practice nurse involvement in the management of adults with type 2 diabetes mellitus attending a general practice: results from a systematic review

AIM

Using the methodology of the Joanna Briggs Institute, a systematic review of current research was performed to determine if the addition of management by nurses had been more effective in improving clinical outcomes of patients with type 2 diabetes attending a general practice compared with standard care.

METHODS

A three-step literature search was conducted for suitable English studies with quantitative clinical outcomes that had been published from January 1990 to May 2014. Randomised controlled trials (RCTs) were particularly sought after; however, other research designs were considered. Articles were assessed by two independent reviewers for methodological validity, prior to inclusion in the review, using standardised critical appraisal instruments from the Joanna Briggs Institute. When possible, quantitative data were pooled in statistical meta-analysis.

RESULTS

Seven studies were of suitable quality and relevance for the review: these included three randomised control trials; two cluster- RCTs; a cluster, nonrandomised, controlled before-after study; and a cluster observational cohort study. These studies yield evidence that nurse management in addition to standard general practitioner care leads to modest improvements in blood pressure and total cholesterol levels in adults with type 2 diabetes attending a general practice.

CONCLUSION

Meta-analysis identified modest, significant improvements amongst participants in nurse management interventions (NMIs) in the following clinical outcomes: mean SBP, mean DBP and mean total cholesterol. The majority of outcomes studied did not show any advantage to adding NMIs to general practitioner care. Two studies reported significant improvements of participants with poor control in mean haemoglobin A1c. An RCT that investigates the effect of NMIs on patients, with poor control in regard to clinical outcomes and cost effectiveness, is recommended.

Effective Universal Coverage of Diabetes Mellitus Type 2 in Chile

Objective:

determine the prevalence of Effective Universal Coverage of Diabetes Mellitus Type 2 in Chile and its relation with the variables: Health Care Coverage of Diabetes Mellitus Type 2; Average of diabetics with metabolic control in 2011-2013; Mortality Rate for Diabetes Mellitus; and Percentage of nurses participating in the Cardiovascular Health Program.

Method:

cross-sectional descriptive study with ecological components that uses documentary sources of the Ministry of Health. It was established that there is correlation between the Universal Effective Coverage of Diabetes Mellitus Type 2 and the independent variables; it was applied the Pearson Coefficient, being significant at the 0.05 level.

Results:

in Chile Universal Health Care Coverage of Diabetes Mellitus Type 2 (HbA1c<7% estimated population) is less than 20%; this is related with Mortality Rate for Diabetes Mellitus and Percentage of nurses participating in the Cardiovascular Health Program, being significant at the 0.01 level.

Conclusion:

effective prevalence of Universal Health Coverage of Diabetes Mellitus Type 2 is low, even though some regions stand out in this research and in the metabolic control of patients who participate in health control program; its relation with percentage of nurses participating in the Cardiovascular Health Program represents a challenge and an opportunity for the health system.

Effectiveness of a training course for general practice nurses in motivation support in type 2 diabetes care: a cluster-randomised trial

Background

Type 2 diabetes is a common metabolic disease with the potential for prevention of complications. The prevention requires a high level of lasting actions from the patients, which may be burdensome. The aim of this trial was to evaluate the effectiveness of a training course for general practice nurses in motivation support at 18 months follow-up in the affiliated type 2 diabetes population.

Methods

Forty general practices with nurse-led diabetes consultations from the area of Aarhus, Denmark were randomised 1∶1 to either intervention or usual practice. Intervention practices were offered a 16-hour Self-determination theory - based course including communication training for general practice nurses delivered over 10 months. The affiliated diabetes populations (aged 40–74 years) were identified from registers (intervention n = 2,005; usual n = 2,029). Primary outcomes were register-based glycated haemoglobin (HbA_1c) -, total cholesterol levels, and well-being measured by the Problem Areas In Diabetes scale (PAID) and the mental component summary score, SF12 (SF12, mcs). Intention-to-treat analyses were performed. Predefined subgroups analyses were performed.

Results

The differences between the intervention- and the control practices’ mean HbA_1c and total cholesterol at follow-up adjusted for baseline values and clustering were respectively: −0.02%-points (95% CI: −0.11 to 0.07; p: 0.67); 0.08 mmol/l (95% CI: 0.01 to 0.15; p: 0.02). Differences in median scores adjusted for clustering were for PAID: 1.25; p = 0.31 and SF12, mcs: 0.99; p = 0.15. Women in intervention practices differed from women in usual practices on mean HbA_1c: −0.12%-points (−0.23 to −0.02; p = 0.02) and SF12, mcs: 2.6; p = 0.01.

Conclusions

Offering a training course for general practice nurses in applying the Self-determination theory in current type 2 diabetes care had no effect compared with usual practice measured by HbA_1c and total cholesterol levels and the well-being at 18 months of follow-up in a comprehensive register-based diabetes population. Subgroup analyses suggested a possible effect in women, which deserves further attention.

Effective Nurse Communication With Type 2 Diabetes Patients

Many type 2 diabetes mellitus patients have difficulties reaching optimal blood glucose control. With patients treated in primary care by nurses, nurse communication plays a pivotal role in supporting patient health. The twofold aim of the present review is to categorize common barriers to nurse–patient communication and to review potentially effective communication methods. Important communication barriers are lack of skills and self-efficacy, possibly because nurses work in a context where they have to perform biomedical examinations and then perform patient-centered counseling from a biopsychosocial approach. Training in patient-centered counseling does not seem helpful in overcoming this paradox. Rather, patient-centeredness should be regarded as a basic condition for counseling, whereby nurses and patients seek to cooperate and share responsibility based on trust. Nurses may be more successful when incorporating behavior change counseling based on psychological principles of self-regulation, for example, goal setting, incremental performance accomplishments, and action planning.

Analysis and improvement of organizational models for the management of patients with type 2 diabetes mellitus: a case study in north-east Italy

PURPOSE

The study aimed to establish whether the organization for the management of type 2 diabetes mellitus at 9 diabetic units (DUs), in 5 neighboring local health authorities (LHAs), was able to (a) comply with the organizational model prescribed by specific regional standards; (b) ensure adequate clinical management of diabetic patients; (c) assess whether the relationship between primary care physicians (PCPs) and diabetologists (SDs) was instrumental to the needs of patients; (d) optimize specialist treatment at the DUs; (e) optimize drug management; and (f) check whether organizational changes led to variations in clinical results.

METHODS

This 6-stage study analyzed procedures, precoded actions, and recordable processes. Stage (1) Defining clinical and organizational endpoints; (2) Drafting flowcharts to describe the actions and work procedures implemented within each LHA; (3) Comparing the flowcharts with the data obtained from related literature; (4) Establishing a protocol shared with PCPs for the management and treatment of patients with type 2 diabetes; (5) Changing the procedures at the DUs; and (6) Evaluating the results. The data were assessed before and after establishing a shared protocol for SDs and PCPs (year 2009 vs 2011).

RESULTS

The study shows inconsistencies in the organization of work in the 5 LHAs; however, collaboration with PCPs has guaranteed: (a) unchanged hemoglobin A1C values before and after applying the protocol; (b) a percentage increase in the number of patients with type 2 diabetes who were identified thanks to these protocols; (c) an increase in the use of biguanides compared to the preprotocol period; and (d) no change in the number of patients hospitalized because of acute complications from type 2 diabetes mellitus.

CONCLUSIONS

This study confirms how adequate collaboration between SDs and PCPs keeps the risk of complications stable. Nevertheless, shared protocols and clearly defined roles are required.

[Diabetes in general practice--were treatment goals reached?]

BACKGROUND

In Norway, most people with diabetes are treated by general practitioners. At our own general practice, we wanted to find out whether we were succeeding in following the Directorate of Health's 2009 clinical guidelines on treatment and management of diabetes.

MATERIAL AND METHOD

All patients with the diagnosis diabetes mellitus in our electronic archive between November 2009 and October 2010 were registered. Those patients on our general practice lists in October 2010 were identified. The patient records were manually reviewed and relevant data recorded.

RESULTS

In all, 271 patients with diabetes attended our surgery for check-ups in October 2010. 11% had type 1 diabetes and 88% had type 2 diabetes. HbA1c was measured in 99% of the diabetes patients, blood pressure in 98% and lipids in 93%. The measurements were taken at our surgery during the past year for 96% of the patients. The treatment goals for HbA1c, systolic blood pressure and LDL cholesterol were reached in, respectively, 55%, 55% and 49% of the patients. 13% reached all three treatment goals. 82% had a check-up with an ophthalmologist. Weight and smoking habits were documented in 85% and 90% respectively. 19% of the patients for whom we had documented data, smoked. Examinations of height, feet and microalbumin were documented in 57%, 35% and 28% of the patients respectively.

INTERPRETATION

The guidelines are being followed on most points to a high degree, and the proportion of patients reaching the stricter treatment goals is consistent with the results of earlier Norwegian surveys. There is the potential for further improvement of these results.

Adherence to international follow-up guidelines in type 2 diabetes: a longitudinal cohort study in Luxembourg

Introduction

Type 2 diabetes is associated with severe micro- and macro-vascular complications. Physicians’ and patients’ adherence to follow-up guidelines permits postponing or reducing these complications. The objectives were to assess the level of adherence to fundamental follow-up guidelines and determine patients’ characteristics associated with this level of adherence in the context of Luxembourg, where no guidelines were implemented.

Study population

The exhaustive residing population treated for type 2 diabetes in Luxembourg during the 2000-2006 period (N = 21,068).

Methods

Seven fundamental criteria were extracted from international guidelines (consultation with the treating physician, HbA1c tests, electrocardiogram, retinal, dental, lipid and renal check-ups). The factors associated with the level of adherence to those criteria were identified using a partial proportional odds model.

Results

In 2006, despite 90% of the patients consulted at least 4 times their treating physician, only 0.6% completed all criteria; 55.0% had no HbA1c test (−8.6 points since 2000) and 31.1% had a renal check-up (+21.6 points). The sex (OR_male: 0.87 [95%CI, 0.83−0.92]), the nationality (OR_NonEU: 0.64 [0.52−0.78]), the type of antidiabetic treatment (OR_oral: 1.48 [1.35−1.63], OR_mixed: 1.35 [1.20−1.52]) and the type of treating physician (OR_G-ID: 0.47 [0.42−0.53]) were the main factors associated with the level of adherence in 2006 (3 or more criteria).

Conclusion

A large percentage of patients were not provided with a systematic annual follow-up between 2000 and 2006. This study highlighted the necessity to promote guidelines in Luxembourg, education for physicians and to launch a national discussion on a disease management program for diabetic patients.

Drug adherence in patients taking oral anticoagulation therapy

Oral anticoagulation has proven to reduce mortality and morbidity of thromboembolic events. One of the most important determinants of the effectiveness and safety of anticoagulation therapy is the adherence to the prescribed therapy. Vitamin K antagonists are characterized by under-utilization, a narrow therapeutic window and multiple food and drug interactions which contribute to a variable dose-response relationship with the risk of insufficient protection and/or increased bleeding risk. The "new" direct oral anticoagulants have demonstrated equal or superior protection and reduced bleeding risks compared to warfarin and are easier to use because of fixed dosing without monitoring of anticoagulation. Controlling of adherence to the direct oral anticoagulants is difficult. Therefore, continuous and regular medication intake represents a pre-requisite for achieving optimal protection. The present review aims to give an overview about the factors that affect drug adherence in patients taking oral anticoagulation drugs and discusses strategies to improve drug adherence.
