Nurse case management to improve glycemic control in diabetic patients in a health maintenance organization. A randomized, controlled trial

Navigating diabetes care inequities: an observational study linking chronic care model's structural elements to process and outcomes of type 2 diabetes care in Belgium

BACKGROUND

Although the Chronic Care Model (CCM) provides the essential structural components of practice organisation to deliver high-quality type 2 diabetes (T2D) care, little is known about which of its elements are most important, and the extent to which it may reduce social inequities in the quality of T2D care. This study aims to assess the association between the implementation of CCM's structural elements and the quality of T2D care processes and outcomes in Flanders (Belgium), paying specific attention to differences by patients' socioeconomic vulnerability.

METHODS

We developed a longitudinal database combining information on primary care practices' CCM implementation, with individual-level health insurance and medical lab data. Our sample included 7,593 T2D patients aged 40 years and above from 58 primary care practices in Flanders, followed up from 2017 to 2019. Medical lab data were available for a subsample of 4,549 patients. By estimating a series of hierarchical mixed-effects models, we assessed the association between primary care practices' CCM implementation and two process and two outcome indicators of T2D care. In addition, we explored cross-level interactions with patients' socioeconomic vulnerability.

RESULTS

Patients were more likely to have their HbA1c tested twice a year and LDL cholesterol tested yearly in practices with a higher overall CCM implementation. Regarding the different CCM elements, the clinical information system and linkages to the community were significantly associated with higher odds of being up-to-date with HbA1c testing, whereas stronger community linkages was the only dimension significantly associated with yearly LDL cholesterol testing. While socioeconomic vulnerable patients were less likely to have their HbA1c tested twice yearly, this difference disappeared in the highest-scoring practices. Regarding the outcome indicators, only a negligible proportion of variation in HbA1c and LDL cholesterol levels was due to systematic differences between practices, and hence, no clinically relevant associations with the CCM elements were found.

CONCLUSION

Our pioneering findings support the social capital pathway, as CCM implementation is associated with a reduction in the healthcare inequity gap in the T2D care process. This suggests that promoting CCM implementation may improve healthcare equity, particularly in regions with significant socioeconomic disparities or high concentrations of deprived individuals.

Impaired Fasting Glucose in Pregnancy: Improved Perinatal Outcomes with Active Glycemic Management

OBJECTIVE

This study aimed to assess the association between active glycemic management and large for gestational age (LGA) neonates and cesarean delivery (CD) among pregnant women with impaired fasting glucose (IFG).

STUDY DESIGN

Retrospective cohort study using electronic health record data of women with IFG who delivered at the Kaiser Permanente Northern California from 2012 to 2017. IFG was defined as isolated fasting glucose ≥95 mg/dL. Women with gestational diabetes mellitus (GDM) or in whom GDM could not be ruled out were excluded. Baseline and treatment characteristics, and pregnancy outcomes were compared among women with IFG who participated in telephonic home glucose monitoring and glycemic management through a centralized standardized program (participants) with those who did not participate (nonparticipants). The relative risks (RRs) of perinatal complications associated with participation versus nonparticipation were estimated with Poisson's regression models.

RESULTS

We identified 1,584 women meeting inclusion criteria of whom 1,151 (72.7%) were participants and 433 (27.3%) were nonparticipants. There were no differences between groups in baseline characteristics or comorbidities, except for higher mean levels of fasting glucose (FG) at the time of IFG diagnosis in participants than in nonparticipants (98.9 vs. 98.0 mg/dL, p = 0.01). Participants received hypoglycemic medications more frequently than nonparticipants (68.2 vs. 0.9%, p < 0.01). The rate of LGA was significantly lower in participants compared with nonparticipants (19.1 vs. 25.0%, p = 0.01). After adjusting for age, race/ethnicity, education, body mass index, and level of FG impairment, the RR for LGA for participants compared with nonparticipants was 0.68, 95% CI: 0.55-0.84. The risk of CD did not differ significantly by participation status, in unadjusted or adjusted analyses.

CONCLUSION

Active standardized glycemic management was associated with a decreased risk of LGA for women with IFG. This finding supports an active glycemic management strategy for patients with IFG during pregnancy to reduce the risk of LGA, similar to GDM management.

KEY POINTS

· Pregnant women with IFG have increased rates of LGA.. · Active management of IFG is associated with a decreased LGA.. · Treatment of IFG like GDM may improve perinatal outcomes..

Quality improvement strategies for diabetes care: Effects on outcomes for adults living with diabetes

BACKGROUND

There is a large body of evidence evaluating quality improvement (QI) programmes to improve care for adults living with diabetes. These programmes are often comprised of multiple QI strategies, which may be implemented in various combinations. Decision-makers planning to implement or evaluate a new QI programme, or both, need reliable evidence on the relative effectiveness of different QI strategies (individually and in combination) for different patient populations.

OBJECTIVES

To update existing systematic reviews of diabetes QI programmes and apply novel meta-analytical techniques to estimate the effectiveness of QI strategies (individually and in combination) on diabetes quality of care.

SEARCH METHODS

We searched databases (CENTRAL, MEDLINE, Embase and CINAHL) and trials registers (ClinicalTrials.gov and WHO ICTRP) to 4 June 2019. We conducted a top-up search to 23 September 2021; we screened these search results and 42 studies meeting our eligibility criteria are available in the awaiting classification section.

SELECTION CRITERIA

We included randomised trials that assessed a QI programme to improve care in outpatient settings for people living with diabetes. QI programmes needed to evaluate at least one system- or provider-targeted QI strategy alone or in combination with a patient-targeted strategy. - System-targeted: case management (CM); team changes (TC); electronic patient registry (EPR); facilitated relay of clinical information (FR); continuous quality improvement (CQI). - Provider-targeted: audit and feedback (AF); clinician education (CE); clinician reminders (CR); financial incentives (FI). - Patient-targeted: patient education (PE); promotion of self-management (PSM); patient reminders (PR). Patient-targeted QI strategies needed to occur with a minimum of one provider or system-targeted strategy.

DATA COLLECTION AND ANALYSIS

We dual-screened search results and abstracted data on study design, study population and QI strategies. We assessed the impact of the programmes on 13 measures of diabetes care, including: glycaemic control (e.g. mean glycated haemoglobin (HbA1c)); cardiovascular risk factor management (e.g. mean systolic blood pressure (SBP), low-density lipoprotein cholesterol (LDL-C), proportion of people living with diabetes that quit smoking or receiving cardiovascular medications); and screening/prevention of microvascular complications (e.g. proportion of patients receiving retinopathy or foot screening); and harms (e.g. proportion of patients experiencing adverse hypoglycaemia or hyperglycaemia). We modelled the association of each QI strategy with outcomes using a series of hierarchical multivariable meta-regression models in a Bayesian framework. The previous version of this review identified that different strategies were more or less effective depending on baseline levels of outcomes. To explore this further, we extended the main additive model for continuous outcomes (HbA1c, SBP and LDL-C) to include an interaction term between each strategy and average baseline risk for each study (baseline thresholds were based on a data-driven approach; we used the median of all baseline values reported in the trials). Based on model diagnostics, the baseline interaction models for HbA1c, SBP and LDL-C performed better than the main model and are therefore presented as the primary analyses for these outcomes. Based on the model results, we qualitatively ordered each QI strategy within three tiers (Top, Middle, Bottom) based on its magnitude of effect relative to the other QI strategies, where 'Top' indicates that the QI strategy was likely one of the most effective strategies for that specific outcome. Secondary analyses explored the sensitivity of results to choices in model specification and priors.  Additional information about the methods and results of the review are available as Appendices in an online repository. This review will be maintained as a living systematic review; we will update our syntheses as more data become available.

MAIN RESULTS

We identified 553 trials (428 patient-randomised and 125 cluster-randomised trials), including a total of 412,161 participants. Of the included studies, 66% involved people living with type 2 diabetes only. Participants were 50% female and the median age of participants was 58.4 years. The mean duration of follow-up was 12.5 months. HbA1c was the commonest reported outcome; screening outcomes and outcomes related to cardiovascular medications, smoking and harms were reported infrequently. The most frequently evaluated QI strategies across all study arms were PE, PSM and CM, while the least frequently evaluated QI strategies included AF, FI and CQI. Our confidence in the evidence is limited due to a lack of information on how studies were conducted.  Four QI strategies (CM, TC, PE, PSM) were consistently identified as 'Top' across the majority of outcomes. All QI strategies were ranked as 'Top' for at least one key outcome. The majority of effects of individual QI strategies were modest, but when used in combination could result in meaningful population-level improvements across the majority of outcomes. The median number of QI strategies in multicomponent QI programmes was three.  Combinations of the three most effective QI strategies were estimated to lead to the below effects:  - PR + PSM + CE: decrease in HbA1c by 0.41% (credibility interval (CrI) -0.61 to -0.22) when baseline HbA1c < 8.3%; - CM + PE + EPR: decrease in HbA1c by 0.62% (CrI -0.84 to -0.39) when baseline HbA1c > 8.3%;  - PE + TC + PSM: reduction in SBP by 2.14 mmHg (CrI -3.80 to -0.52) when baseline SBP < 136 mmHg; - CM + TC + PSM: reduction in SBP by 4.39 mmHg (CrI -6.20 to -2.56) when baseline SBP > 136 mmHg;  - TC + PE + CM: LDL-C lowering of 5.73 mg/dL (CrI -7.93 to -3.61) when baseline LDL < 107 mg/dL; - TC + CM + CR: LDL-C lowering by 5.52 mg/dL (CrI -9.24 to -1.89) when baseline LDL > 107 mg/dL. Assuming a baseline screening rate of 50%, the three most effective QI strategies were estimated to lead to an absolute improvement of 33% in retinopathy screening (PE + PR + TC) and 38% absolute increase in foot screening (PE + TC + Other).

AUTHORS' CONCLUSIONS

There is a significant body of evidence about QI programmes to improve the management of diabetes. Multicomponent QI programmes for diabetes care (comprised of effective QI strategies) may achieve meaningful population-level improvements across the majority of outcomes. For health system decision-makers, the evidence summarised in this review can be used to identify strategies to include in QI programmes. For researchers, this synthesis identifies higher-priority QI strategies to examine in further research regarding how to optimise their evaluation and effects. We will maintain this as a living systematic review.

Pregnancy post-bariatric surgery: Improved outcomes with telephonic nutritional management program

BACKGROUND

Pregnancies post-bariatric surgery are increasingly common. It is important to understand how to manage prenatal care in this high-risk population to optimize perinatal outcomes.

OBJECTIVE

To determine among pregnancies post-bariatric surgery whether participation in a telephonic nutritional management program was associated with improved perinatal outcomes and nutritional adequacy.

STUDY DESIGN

Retrospective cohort study of pregnancies post-bariatric surgery from 2012 to 2018. Participation in a telephonic management program with nutritional counseling, monitoring and nutritional supplement adjustment. Modified Poisson Regression estimated the relative risk using propensity score methods to account for baseline differences between the patients who participated in the program and patients who did not.

RESULTS

1575 pregnancies occurred post-bariatric surgery, of which 1142 (72.5 % of pregnancies) participated in the telephonic nutritional management program. Participants in the program were less likely than non-participants to have a preterm birth (aRR 0.48, 95 % CI 0.35-0.67), preeclampsia (aRR 0.43, 95 % CI (0.27-0.69)), gestational hypertension (aRR 0.62, 95 % CI 0.41-0.93), and to have neonates admitted to a Level 2 or 3 (aRR 0.61, 95 % CI0.39-0.94; aRR 0.66, 95 % CI 0.45-0.97, respectively), after adjusting for the propensity score to account for baseline differences. Risk of cesarean delivery, gestational weight gain, glucose intolerance and birthweight did not differ by participation. Among 593 pregnancies with nutritional labs available, participants in the telephonic program were less likely to have nutritional inadequacy in late pregnancy (aRR 0.91, 95 % CI 0.88-0.94).

CONCLUSION

Participation in a telephonic nutritional management program post-bariatric surgery was associated with improved perinatal outcomes and nutritional adequacy.

A Study to Compare a CHW-Led Versus Physician-Led Intervention for Prostate Cancer Screening Decision-Making among Black Men

Introduction

Prostate cancer is the second leading cause of cancer deaths among men in the United States and harms Black men disproportionately. Most US men are uninformed about many key facts important to make an informed decision about prostate cancer. Most experts agree that it is important for men to learn about these problems as early as possible in their lifetime.

Objectives

To compare the effect of a community health worker (CHW)-led educational session with a physician-led educational session that counsels Black men about the risks and benefits of prostate-specific antigen (PSA) screening.

Methods

One hundred eighteen Black men recruited in 8 community-based settings attended a prostate cancer screening education session led by either a CHW or a physician. Participants completed surveys before and after the session to assess knowledge, decisional conflict, and perceptions about the intervention. Both arms used a decision aid that explains the benefits, risks, and controversies of PSA screening and decision coaching.

Results

There was no significant difference in decisional conflict change by group: 24.31 physician led versus 30.64 CHW led (P=.31). The CHW-led group showed significantly greater improvement on knowledge after intervention, change (SD): 2.6 (2.81) versus 5.1 (3.19), P<.001). However, those in the physician-led group were more likely to agree that the speaker knew a lot about PSA testing (P<.001) and were more likely to trust the speaker (P<.001).

Conclusions

CHW-led interventions can effectively assist Black men with complex health decision-making in community-based settings. This approach may improve prostate cancer knowledge and equally minimize decisional conflict compared with a physician-led intervention.

Effectiveness of registered nurses on patient outcomes in primary care: a systematic review

BACKGROUND

Globally, registered nurses (RNs) are increasingly working in primary care interdisciplinary teams. Although existing literature provides some information about the contributions of RNs towards outcomes of care, further evidence on RN workforce contributions, specifically towards patient-level outcomes, is needed. This study synthesized evidence regarding the effectiveness of RNs on patient outcomes in primary care.

METHODS

A systematic review was conducted in accordance with Joanna Briggs Institute methodology. A comprehensive search of databases (CINAHL, MEDLINE Complete, PsycINFO, Embase) was performed using applicable subject headings and keywords. Additional literature was identified through grey literature searches (ProQuest Dissertations and Theses, MedNar, Google Scholar, websites, reference lists of included articles). Quantitative studies measuring the effectiveness of a RN-led intervention (i.e., any care/activity performed by a primary care RN) that reported related outcomes were included. Articles were screened independently by two researchers and assessed for bias using the Integrated Quality Criteria for Review of Multiple Study Designs tool. A narrative synthesis was undertaken due to the heterogeneity in study designs, RN-led interventions, and outcome measures across included studies.

RESULTS

Forty-six patient outcomes were identified across 23 studies. Outcomes were categorized in accordance with the PaRIS Conceptual Framework (patient-reported experience measures, patient-reported outcome measures, health behaviours) and an additional category added by the research team (biomarkers). Primary care RN-led interventions resulted in improvements within each outcome category, specifically with respect to weight loss, pelvic floor muscle strength and endurance, blood pressure and glycemic control, exercise self-efficacy, social activity, improved diet and physical activity levels, and reduced tobacco use. Patients reported high levels of satisfaction with RN-led care.

CONCLUSIONS

This review provides evidence regarding the effectiveness of RNs on patient outcomes in primary care, specifically with respect to satisfaction, enablement, quality of life, self-efficacy, and improvements in health behaviours. Ongoing evaluation that accounts for primary care RNs' unique scope of practice and emphasizes the patient experience is necessary to optimize the delivery of patient-centered primary care.

The effect of integrated health care in patients with hypertension and diabetes: a systematic review and meta-analysis

Background

A growing number of studies show that integrated health care provides comprehensive and continuous care to patients with hypertension or diabetes. However, there is still no consensus about the effect of integrated health care on patients with hypertension or diabetes. The objective of this study was to verify the effectiveness of integrated health care for patients with hypertension or diabetes by using a systematic review and meta-analysis.

Methods

The study searched multiple English and Chinese electronic databases. The search period was from database inception to 31 October 2020. Systematic reviews and meta-analyses were conducted after assessing the risk of bias of each study.

Results

Sixteen studies that involved 5231 patients were included in this study. The results of the systematic review revealed that systolic blood pressure (SBP), diastolic blood pressure (DBP), body mass index (BMI) and glycosylated haemoglobin (HbA1c) are commonly used indicators for patients with hypertension or diabetes. Individual models and group- and disease-specific models are the most commonly used models of integrated health care. All the studies were from high-income and middle-income countries. Meta-analysis showed that integrated health care significantly improved SBP, DBP and HbA1c but not BMI. A comparison of interventions lasting 6 and 12 months for diabetes was conducted, and HbA1c was decreased after 12 months. The changes in SBP and DBP were statistically significant after using group- and disease-specific model but not individual models. HbA1c was significantly improved after using group- and disease-specific models and individual models.

Conclusion

Integrated health care is a useful tool for disease management, and individual models and group- and disease-specific models are the most commonly used models in integrated health care. Group- and disease-specific models are more effective than individual models in the disease management of hypertension patients. The duration of intervention should be considered in the disease management of patients with diabetes, and interventions longer than 12 months are recommended. The income level may affect the model of integrated health care in selecting which disease to intervene, but this point still needs support from more studies.

Effectiveness of registered nurses on system outcomes in primary care: a systematic review

BACKGROUND

Internationally, policy-makers and health administrators are seeking evidence to inform further integration and optimal utilization of registered nurses (RNs) within primary care teams. Although existing literature provides some information regarding RN contributions, further evidence on the impact of RNs towards quality and cost of care is necessary to demonstrate the contribution of this role on health system outcomes. In this study we synthesize international evidence on the effectiveness of RNs on care delivery and system-level outcomes in primary care.

METHODS

A systematic review was conducted in accordance with Joanna Briggs Institute methodology. Searches were conducted in CINAHL, MEDLINE Complete, PsycINFO, and Embase for published literature and ProQuest Dissertations and Theses and MedNar for unpublished literature between 2019 and 2022 using relevant subject headings and keywords. Additional literature was identified through Google Scholar, websites, and reference lists of included articles. Studies were included if they measured effectiveness of a RN-led intervention (i.e., any care/activity performed by a primary care RN within the context of an independent or interdependent role) and reported outcomes of these interventions. Included studies were published in English; no date or location restrictions were applied. Risk of bias was assessed using the Integrated Quality Criteria for Review of Multiple Study Designs tool. Due to the heterogeneity of included studies, a narrative synthesis was undertaken.

RESULTS

Seventeen articles were eligible for inclusion, with 11 examining system outcomes (e.g., cost, workload) and 15 reporting on outcomes related to care delivery (e.g., illness management, quality of smoking cessation support). The studies suggest that RN-led care may have an impact on outcomes, specifically in relation to the provision of medication management, patient triage, chronic disease management, sexual health, routine preventative care, health promotion/education, and self-management interventions (e.g. smoking cessation support).

CONCLUSIONS

The findings suggest that primary care RNs impact the delivery of quality primary care, and that RN-led care may complement and potentially enhance primary care delivered by other primary care providers. Ongoing evaluation in this area is important to further refine nursing scope of practice policy, determine the impact of RN-led care on outcomes, and inform improvements to primary care infrastructure and systems management to meet care needs.

Self-Management Nursing Intervention for Controlling Glucose among Diabetes: A Systematic Review and Meta-Analysis

As the diabetic population increases, self-management of diabetes, a chronic disease, is important. Given that self-management nursing interventions using various techniques have been developed, an analysis of their importance is crucial. This study aimed to identify the overall effects of self-management nursing interventions on primary (HbA1c) and secondary (self-care, self-efficacy, fasting blood sugar level blood pressure, lipid, body mass index, waist circumference, distress, anxiety, depression, and quality of life) outcomes in diabetes. Systematic review and meta-analysis were used. The meta-analysis involved the synthesis of effect size; tests of homogeneity and heterogeneity; trim and fill plot; Egger’s regression test; and Begg’s test for assessing publication bias. The overall effect on HbA1c was −0.55, suggesting a moderate effect size, with HbA1c decreasing significantly after nursing interventions. Among the nursing interventions, the overall effect on HbA1c of nurse management programs, home visiting, and customized programs was −0.25, −0.61, and −0.65, respectively, a small or medium effect size, and was statistically significant. Healthcare professionals may encourage people with diabetes to engage in self-management of their glucose levels, such as patient-centered customized intervention. Interventions that reflect the individual’s characteristics and circumstances are effective in enabling self-management.

Clinical Trial Protocol for a Randomized Trial of Community Health Worker-led Decision Coaching to Promote Shared Decision-making on Prostate Cancer Screening Among Black Male Patients and Their Providers

We propose a randomized controlled trial to evaluate the effectiveness of a community health worker-led decision-coaching program to facilitate shared decision-making for prostate cancer screening decisions by Black men at a primary care federally qualified health center.

Telepharmacy: A Potential Alternative Approach for Diabetic Patients During the COVID-19 Pandemic

The use of telepharmacy technology allows pharmacists to provide clinical pharmaceutical services to patients with diabetes mellitus (DM) who need regular services during the COVID-19 pandemic while maintaining distance and minimizing face-to-face meetings. The purpose of this review article was to identify the impact of telepharmacy intervention by pharmacists in diabetic patients by reviewing clinical outcomes and patient therapy adherences. A literature search was conducted through the PubMed database using the terms "telemedicine", "telepharmacy", "telehealth" and "telephone" in combination with "pharmacist", 'diabetes' and 'COVID-19' or "Pandemic". From a total of 67 articles identified, 14 research articles conform to the inclusion criteria. Telephone is the most widely used communication model (n = 11). All studies had a positive impact on clinical outcomes and three studies did not provide significant result on therapy adherence. The use of telepharmacy can be maximized and used on a vast scale, with the design of devices and technologies making it easier for pharmacists and diabetic patients to provide and receive clinical pharmaceutical services during the COVID-19 pandemic.

Cost-Effectiveness of Technology-Assisted Case Management in Low-Income, Rural Adults with Type 2 Diabetes

Objective: The objective of this study was to examine whether delivering technology-assisted case management (TACM) with medication titration by nurses under physician supervision is cost effective compared with usual care (standard office procedures) in low-income rural adults with type 2 diabetes.

Methods: One hundred and thirteen low-income, rural adults with type 2 diabetes and hemoglobin A1c (HbA1c) ≥8%, were randomized to a TACM intervention or usual care. Effectiveness was measured as differences in HbA1c between the TACM and usual care groups at 6 months. Total cost per patient included intervention or usual care cost, medical care cost, and income loss associated with lost workdays. The total cost per patient and HbA1c were used to estimate a joint distribution of incremental cost and incremental effect of TACM compared with usual care. Incremental cost-effectiveness ratios (ICERs) were estimated to summarize the cost-effectiveness of the TACM intervention relative to usual care to decrease HbA1c by 1%.

Results: Costs due to intervention, primary care, other health care, emergency room visits, and workdays missed showed statistically significant differences between the groups (usual care $1,360.49 vs. TACM $5,379.60, p=0.004), with an absolute cost difference of $4,019.11. Based on the intervention cost per patient and the change in HbA1c, the median bootstrapped ICERs was estimated to be $6,299.04 (standard error=731.71) per 1% decrease in HbA1c.

Conclusion: Based on these results, a 1% decrease in HbA1c can be obtained with the TACM intervention at an approximate cost of $6,300; therefore, it is a cost-effective option for treating vulnerable populations of adults with type 2 diabetes.

Randomized trial of community health worker-led decision coaching to promote shared decision-making for prostate cancer screening among Black male patients and their providers

BACKGROUND

Black men are disproportionately affected by prostate cancer, the most common non-cutaneous malignancy among men in the USA. The United States Preventive Services Task Force (USPSTF) encourages prostate-specific antigen (PSA) testing decisions to be based on shared decision-making (SDM) clinician professional judgment, and patient preferences. However, evidence suggests that SDM is underutilized in clinical practice, especially among the most vulnerable patients. The purpose of this study is to evaluate the efficacy of a community health worker (CHW)-led decision-coaching program to facilitate SDM for prostate cancer screening among Black men in the primary care setting, with the ultimate aim of improving/optimizing decision quality.

METHODS

We proposed a CHW-led decision-coaching program to facilitate SDM for prostate cancer screening discussions in Black men at a primary care FQHC. This study enrolled Black men who were patients at the participating clinical site and up to 15 providers who cared for them. We estimated to recruit 228 participants, ages 40-69 to be randomized to either (1) a decision aid along with decision coaching on PSA screening from a CHW or (2) receiving a decision aid along with CHW-led interaction on modifying dietary and lifestyle to serve as an attention control. The independent randomization process was implemented within each provider and we controlled for age by dividing patients into two strata: 40-54 years and 55-69 years. This sample size sufficiently powered the detection differences in the primary study outcomes: knowledge, indicative of decision quality, and differences in PSA screening rates. Primary outcome measures for patients will be decision quality and decision regarding whether to undergo PSA screening. Primary outcome measures for providers will be acceptability and feasibility of the intervention. We will examine how decision coaching about prostate cancer screening impact patient-provider communication. These outcomes will be analyzed quantitatively through objective, validated scales and qualitatively through semi-structured, in-depth interviews, and thematic analysis of clinical encounters. Through a conceptual model combining elements of the Preventative Health Care Model (PHM) and Informed Decision-Making Model, we hypothesize that the prostate cancer screening decision coaching intervention will result in a preference-congruent decision and decisional satisfaction. We also hypothesize that this intervention will improve physician satisfaction with counseling patients about prostate cancer screening.

DISCUSSION

Decision coaching is an evidence-based approach to improve decision quality in many clinical contexts, but its efficacy is incompletely explored for PSA screening among Black men in primary care. Our proposal to evaluate a CHW-led decision-coaching program for PSA screening has high potential for scalability and public health impact. Our results will determine the efficacy, cost-effectiveness, and sustainability of a CHW intervention in a community clinic setting in order to inform subsequent widespread dissemination, a critical research area highlighted by USPSTF.

TRIAL REGISTRATION

Effectiveness of nurse-led intervention on self-management, self-efficacy and blood glucose level among patients with Type 2 diabetes mellitus

Background This study assesses the effectiveness of nurse-led intervention on self-management, self-efficacy, and blood glucose level among patients with Type 2 diabetes mellitus (DM) attending diabetic Out patient department (OPD) in Sri Ramachandra Hospital, Chennai. Methods In this study, the experimental group received nurse-led intervention on video-assisted teaching regarding nature of the disease condition including, diet, medication, hand and leg exercises, home care management, for 30 mins. Then a demonstration of hand and leg exercise was done followed by return demonstration done by the participants. The participants in the control group did not receive nurse-led intervention; they received only routine care. On the 15th day, when the patients came for the first follow-up, posttest was conducted for both the experimental and control groups. Results There was a statistically considerable difference noted in self-management (t=29.639; p<0.001), self-efficacy (t=28.293; p<0.001), FBS (t=2.415; p<0.05), and PPBS (t=2.102; p<0.05) in the posttest among patients with Type 2 DM in the experimental group. Conclusions The study concluded that the nurse-led intervention through video-assisted teaching is an effective method to recover self-management and self-efficacy as well as reduce the fasting blood sugar and postprandial blood sugar among patients with Type 2 DM.

Effect of Peer Mentors in Diabetes Self-management vs Usual Care on Outcomes in US Veterans With Type 2 Diabetes: A Randomized Clinical Trial

IMPORTANCE

Diabetes is a substantial public health issue. Peer mentoring is a low-cost intervention for improving glycemic control in patients with diabetes. However, long-term effects of peer mentoring and creation of sustainable models are not well studied.

OBJECTIVE

Assess the effects of a peer support intervention for improving glycemic control in patients with diabetes and evaluate a model in which former mentees serve as mentors.

DESIGN, SETTING, AND PARTICIPANTS

A randomized clinical trial was conducted from September 27, 2012, to March 21, 2018, at the Corporal Michael J. Crescenz Medical Center. US veterans with type 2 diabetes aged 30 to 75 years with hemoglobin A1C (HbA1c) greater than 8% received support over 6 months from peers with prior poor glycemic control but who had achieved HbA1c less than or equal to 7.5% (phase 1). Phase 1 mentees were then randomized to become a mentor or not to new randomly assigned participants in phase 2. Outcomes were assessed at 6 and 12 months. Data were analyzed from October 5, 2016, to September 4, 2018.

INTERVENTIONS

Mentors who received an initial training session and monthly reinforcement training were assigned 1 mentee and given $20 for each month they contacted their mentee at least weekly.

MAIN OUTCOMES AND MEASURES

Primary outcome was HbA1c change at 6 months. Secondary outcomes included HbA1c change at 12 months and change in low-density lipoprotein, blood pressure, diabetes quality of life, and depression symptoms at 6 and 12 months.

RESULTS

The study enrolled 365 participants into phase 1 and 122 participants into phase 2. Most participants were Black (341 [66%]) and male (454 [96%]), with a mean (SD) age of 60 (7.5) years. Mean phase 1 HbA1c change at 6 months for usual care was -0.20% (95% CI, -0.46% to 0.06%) vs -0.52% (95% CI, -0.76% to -0.29%) for mentees (P = .06). Mean phase 2 HbA1c change at 6 months for usual care was -0.46% (95% CI, -1.02% to 0.10%) vs 0.08% (95% CI, -0.42% to 0.57%) for mentees (P = .16). There were no differences in secondary outcomes or HbA1c levels at 12 months. There was no benefit to past mentees who became mentors.

CONCLUSIONS AND RELEVANCE

In this randomized clinical trial, a peer mentor intervention did not improve 6-month HbA1c levels and did not have sustained benefits.

Alternative care providers in rheumatoid arthritis patient care: a queueing and simulation analysis

Patients diagnosed with rheumatoid arthritis require lifelong monitoring by a rheumatologist. Initiation of the disease-modifying anti-rheumatic drug therapy within twelve weeks of the onset of symptoms is crucial to prevent joint damage and functional disability. We examine the impact of the engagement of alternate care providers (ACP) in alleviating delay due to limited rheumatologist capacity. Using queueing theory and discrete-event simulation, we model rheumatologist-only and rheumatologist-with-ACP system configurations as closed, multi-class queueing networks with class switching.Using summary data from an actual rheumatology clinic for illustration, we analyze various parameter conditions to aid clinic managers and policymakers in decisions concerning capacity allocations and feasible patient panel size that impact timeliness of care and resource utilization.Results not only confirm that a substantial increase in RA patient panel size with an ACP involved in the care of follow-up patients but also demonstrates the boundaries for feasible panel sizes and workload allocation.

NUrse-led COntinuum of care for people with Diabetes and prediabetes (NUCOD) in Nepal: study protocol for a cluster randomized controlled trial

BACKGROUND

The purpose of this study will be to improve diabetes prevention, access to care and advocacy through a novel cost-effective nurse-led continuum of care approach that incorporates diabetes prevention, awareness, screening and management for low-income settings, and furthermore utilizes the endeavor to advocate for establishing a standard diabetes program in Nepal.

METHODS

We will conduct a two-arm, parallel group, stratified cluster randomized controlled trial of the NUrse-led COntinuum of care for people with Diabetes (N1 = 200) and prediabetes (N2 = 1036) (NUCOD) program, with primary care centers (9 outreach centers and 17 government health posts) as a unit of randomization. The NUCOD program will be delivered through the trained diabetes nurses in the community to the intervention group and the outcomes will be compared with the usual treatment group at 6 and 12 months of the intervention. The primary outcome will be the change in glycated hemoglobin (HbA1c) level among diabetes individuals and progression to type 2 diabetes among prediabetes individuals, and implementation outcomes measured using the RE-AIM (reach, effectiveness, adoption, implementation and maintenance) framework. Outcomes will be analyzed on an intention-to-treat basis.

DISCUSSION

The results of this trial will provide information about the effectiveness of the NUCOD program in improving clinical outcomes for diabetes and prediabetes individuals, and implementation outcomes for the organization. The continuum of care model can be used for the prevention and management of diabetes and other noncommunicable diseases within and beyond Nepal with similar context.

Blended Collaborative Care to Treat Heart Failure and Comorbid Depression: Rationale and Study Design of the Hopeful Heart Trial

OBJECTIVE

Despite numerous improvements in care, morbidity from heart failure (HF) has remained essentially unchanged in recent years. One potential reason is that depression, which is comorbid in approximately 40% of hospitalized HF patients and associated with adverse HF outcomes, often goes unrecognized and untreated. The Hopeful Heart Trial is the first study to evaluate whether a widely generalizable telephone-delivered collaborative care program for treating depression in HF patients improves clinical outcomes.

METHODS

The Hopeful Heart Trial aimed to enroll 750 patients with reduced ejection fraction (HFrEF) (ejection fraction ≤ 45%) including the following: (A) 625 patients who screened positive for depression both during their hospitalization (Patient Health Questionnaire [PHQ-2]) and two weeks following discharge (PHQ-9 ≥ 10); and (B) 125 non-depressed control patients (PHQ-2(-)/PHQ-9 < 5). We randomized depressed patients to either their primary care physician's "usual care" (UC) or to one of two nurse-delivered 12-month collaborative care programs for (a) depression and HFrEF ("blended") or (b) HrEFF alone (enhanced UC). Our co-primary hypotheses will test whether "blended" care can improve mental health-related quality of life versus UC and versus enhanced UC, respectively, on the Mental Component Summary of the Short-Form 12 Health Survey. Secondary hypotheses will evaluate the effectiveness of our interventions on mood, functional status, hospital readmissions, deaths, provision of evidence-based care for HFrEF, and treatment costs.

RESULTS

Not applicable.

CONCLUSIONS

The Hopeful Heart Trial will determine whether "blended" collaborative care for depression and HFrEF is more effective at improving patient-relevant outcomes than collaborative care for HFrEF alone or doctors' UC for HFrEF.

Cost-effectiveness of intensive interventions compared to standard care in individuals with type 2 diabetes: A systematic review and critical appraisal of decision-analytic models

AIMS

The objective of this systematic review is to identify and assess the quality of published decision-analytic models evaluating the long-term cost-effectiveness of target-driven intensive interventions for single and multifactorial risk factor control compared to standard care in people with type 2 diabetes.

METHODS

We searched the electronic databases MEDLINE, the National Health Service Economic Evaluation Database, Web of Science and the Cochrane Library from inception to October 31, 2019. Articles were eligible for inclusion if the studies had used a decision-analytic model evaluating both the long-term costs and benefits associated with intensive interventions for risk factor control compared to standard care in people with type 2 diabetes. Data were extracted using a standardised form, while quality was assessed using the decision-analytic model-specific Philips-criteria.

RESULTS

Overall, nine articles (11 models) were identified, four models evaluated intensive glycaemic control, three evaluated intensive blood pressure control, two evaluated intensive lipid control, and two evaluated intensive multifactorial interventions. Six reported using discrete-time simulations modelling approach, whereas five reported using a Markov modelling framework. The majority, seven studies, reported that the intensive interventions were dominant or cost-effective, given the assumptions and analytical perspective taken. The methodological and reporting quality of the studies was generally weak, with only four studies fulfilling more than 50% of their applicable Philips-criteria.

CONCLUSIONS

This is the first systematic review of decision-analytic models of target-driven intensive interventions for single and multifactorial risk factor control in individuals with type 2 diabetes. Identified shortcomings are lack of transparency in data identification and evidence synthesis as well as for the selection of the modelling approaches. Future models should aim to include greater evaluation of the quality of the data sources used and the assessment of uncertainty in the model.

Effectiveness of non-pharmacological strategies in the management of type 2 diabetes in primary care: a protocol for a systematic review and network meta-analysis

INTRODUCTION

Despite the increasing number of drugs and various guidelines on the management of type 2 diabetes mellitus (T2DM), several patients continue with the disease uncontrolled. There are several non-pharmacological treatments available for managing T2DM, but various of them have never been compared directly to determine the best strategies.

OBJECTIVE

This study will evaluate the comparative effects of non-pharmacological strategies in the management of T2DM in primary care or community settings.

METHODS AND ANALYSIS

We will perform a systematic review and network meta-analysis (NMA), and will include randomised controlled trials if one of the following interventions were applied in adult patients with T2DM: nutritional therapy, physical activity, psychological interventions, social interventions, multidisciplinary lifestyle interventions, diabetes self-management education and support (DSMES), technology-enabled DSMES, interventions delivered only either by pharmacists or by nurses, self-blood glucose monitoring in non-insulin-treated T2DM, health coaching, benchmarking and usual care. The primary outcome will be glycaemic control (glycated haemoglobin (HbA1c) (%)), and the secondary outcomes will be weight loss, quality of life, patient satisfaction, frequency of cardiovascular events and deaths, number of patients in each group with HbA1c <7, adverse events and medication adherence. We have developed search strategies for Embase, Medline, Latin American and Caribbean Health Sciences Literature, Cochrane Central Register of Controlled Trials, Trip database, Scopus, Web of Science, Cumulative Index to Nursing and Allied Health Literature Australasian Medical Index and Chinese Biomedical Literature Database. Four reviewers will assess the studies for their eligibility and their risk of bias in pairs and independently. An NMA will be performed using a Bayesian hierarchical model, and the treatment hierarchy will be obtained using the surface under the cumulative ranking curve. To determine our confidence in an overall treatment ranking from the NMA, we will follow the Grading of Recommendations Assessment, Development and Evaluation approach.

ETHICS AND DISSEMINATION

As no primary data collection will be undertaken, no formal ethical assessment is required. We plan to present the results of this systematic review in a peer-reviewed scientific journal, conferences and the popular press.

The Chronic Liver Disease Nurse Role in Australia: Describing 10 Years of a New Role in Cirrhosis Management

Cirrhosis of the liver is increasing, with growing patient numbers in hospital outpatient departments, as well as increasing admissions due to decompensated liver disease. Decompensated cirrhosis of the liver is a common and debilitating illness causing disability, readmissions to hospital, and decreased quality of life, and can lead to liver cancer. The advent of the chronic liver disease nurse (CLDN) position in our hospital in 2009 was the first role in Australia dedicated to providing care to patients with cirrhosis. The role incorporates the care of patients with stable compensated disease, case management of patients with complications of decompensated disease, and hepatocellular carcinoma coordination. After a pilot randomized controlled trial and almost 10 years of service, this article describes the role of the CLDN and presents key performance indicators that will assist other centers considering introducing the role or elements of it into their service.

DIVERT-Collaboration Action Research and Evaluation (CARE) Trial Protocol: a multiprovincial pragmatic cluster randomised trial of cardiorespiratory management in home care

INTRODUCTION

Home care clients are increasingly medically complex, have limited access to effective chronic disease management and have very high emergency department (ED) visitation rates. There is a need for more appropriate and targeted supportive chronic disease management for home care clients. We aim to evaluate the effectiveness and preliminary cost effectiveness of a targeted, person-centred cardiorespiratory management model.

METHODS AND ANALYSIS

The Detection of Indicators and Vulnerabilities of Emergency Room Trips (DIVERT) - Collaboration Action Research and Evaluation (CARE) trial is a pragmatic, cluster-randomised, multicentre superiority trial of a flexible multicomponent cardiorespiratory management model based on the best practice guidelines. The trial will be conducted in partnership with three regional, public-sector, home care providers across Canada. The primary outcome of the trial is the difference in time to first unplanned ED visit (hazard rate) within 6 months. Additional secondary outcomes are to identify changes in patient activation, changes in cardiorespiratory symptom frequencies and cost effectiveness over 6 months. We will also investigate the difference in the number of unplanned ED visits, number of inpatient hospitalisations and changes in health-related quality of life. Multilevel proportional hazard and generalised linear models will be used to test the primary and secondary hypotheses. Sample size simulations indicate that enrolling 1100 home care clients across 36 clusters (home care caseloads) will yield a power of 81% given an HR of 0.75.

ETHICS AND DISSEMINATION

Ethics approval was obtained from the Hamilton Integrated Research Ethics Board as well as each participating site's ethics board. Results will be submitted for publication in peer-reviewed journals and for presentation at relevant conferences. Home care service partners will also be informed of the study's results. The results will be used to inform future support strategies for older adults receiving home care services.

Team-Based Care to Improve Diabetes Management: A Community Guide Meta-analysis

CONTEXT

Team-based care has been increasingly used to deliver care for patients with chronic conditions, but its effectiveness for managing diabetes has not been systematically assessed.

EVIDENCE ACQUISITION

RCTs were identified from two sources: a high-quality, broader review comparing 11 quality improvement strategies for diabetes management (database inception to July 2010), and an updated search using the same search strategy (July 2010-October 2015).

EVIDENCE SYNTHESIS

Thirty-five studies were included in the current review; a majority focused on patients with Type 2 diabetes. Teams included patients, their primary care providers, and one or two additional healthcare professionals (most often nurses or pharmacists). Random effect meta-analysis showed that, compared with controls, team-based care was associated with greater reductions in blood glucose levels (-0.5% in HbA1c, 95% CI= -0.7, -0.3) and greater improvements in blood pressure and lipid levels. Interventions also increased the proportion of patients who reached target blood glucose, blood pressure, and lipid levels, based on American Diabetes Association guidelines available at the time. Data analysis was completed in 2016.

CONCLUSIONS

For patients with Type 2 diabetes, team-based care improves blood glucose, blood pressure, and lipid levels.

Impacts of nurse-led clinic and nurse-led prescription on hemoglobin A1c control in type 2 diabetes: A meta-analysis

BACKGROUND

To evaluate the impacts of nurse-led clinic and nurse-led prescription on hemoglobin A1c (HbA1c) control in type 2 diabetes.

METHODS

We searched relevant publications in English and Chinese database and conducted meta-analysis by Stata 12.0. We divided the case groups of included studies into 2 categories according to the role of nurse: nurse-led clinic and nurse-led prescription. Nurse-led clinic was implemented on the basis of standard diabetes care provided by doctor, and control group also receive the standard diabetes care but without nurse-led clinic. The doctor mentioned above might work alone or in a health care team. Nurse-led prescription was prescribed by nurse independently and compared with that of doctor.

RESULTS

The meta-analysis shown that, compared with the standard diabetes care, nurse-led clinic significantly decreases HbA1c level (standard mean difference [SMD] = -0.767; 95% confidence interval [CI]: -1.062, -0.471; P < .001). In subgroup analysis, nurse-led clinic also had positive impacts on controlling HbA1c level, no matter in developed countries (SMD = -0.353; 95% CI: -0.6, -0.106; P = .005) or developing countries (SMD = -1.114; 95% CI: -1.498, -0.73; P < .001). Additionally, there was no significant difference between nurse-led prescription and doctor prescription in controlling HbA1c levels (SMD = -0.203; 95% CI: -0.434, 0.029; P = .086).

CONCLUSION

The nurse-led clinic had positive significance for HbA1c control. Meanwhile, the impact of nurse-led prescription on controlling HbA1c is comparable to that of doctor. It is valuable to provide nurse-led clinic on the basis of standard diabetes care provided by doctor to better control HbA1c, and nurse-led prescription should be provided when doctor-led service is limited.

Spirituality, Social Support, and Diabetes: A Cross-Sectional Study of People Enrolled in a Nurse-Led Diabetes Management Program in Peru

INTRODUCTION

In Peru, people living with diabetes mellitus (PLDM) represent 7% of the adult population, each with a $54,000 lifetime cost. For Latinos, spirituality provides meaning and purpose of life while social support affects behavioral choices and adherence decisions. The purpose of this study was to determine the relationship between spirituality and social support for PLDM participating in a nurse-led diabetes management program in a public hospital in Lima, Peru.

METHOD

This cross-sectional study included adult PLDM (N = 54). The instrument included demographic items and the Spanish versions of the social/vocational concern dimension of the Diabetes Quality of Life Questionnaire and the Reed's scale of spiritual perspective.

RESULTS

There was an inverse relation between social support and spiritually practices (p = .020) and spiritual beliefs (p = .005). PLDM with 5 years or more in the program had significantly higher scores in social support (p = .020) and spiritual practices (p = .010).

CONCLUSION

Spirituality and social support are important factors for managing PLDM. Nurse-led diabetes management programs with Latino participants should consider targeted spiritual and social support strategies to expand the holistic management. Future studies should explore the impact and effectiveness of spiritual and social support interventions on clinical outcomes.

A new model for diabetes-focused capacity building - lessons from Sri Lanka

Sri Lanka is experiencing a rapid increase in the number of people with diabetes mellitus (DM) due to population growth and aging. Physician shortages, outdated technology, and insufficient health education have contributed to the difficulties associated with managing the burden of disease. New models of chronic disease management are needed to address the increasing prevalence of DM.

Medical students, business students, and faculty members from the University of Michigan partnered with the Grace Girls’ Home, Trincomalee General Hospital, and Selvanayakapuram Central Hospital to identify and train diabetes-focused medical assistants (MAs) to collect and enter patient data and educate patients about their disease. Return visits to these MAs were encouraged so that patient progress and disease progression could be tracked longitudinally. Data entry was conducted through a cloud-based mechanism, facilitating patient management and descriptive characterization of the population. We implemented this pilot program in June 2016 in coordination with Trincomalee General Hospital and Selvanayakapuram Central Hospital. Over a 12-month period, 93 patients were systematically assessed by the medical assistants. All patients received education and were provided materials after the visit to better inform them about the importance of controlling their disease. Fifteen percent (14/93) of patients returned for follow-up consultation.

Trained MAs have the potential to provide support to physicians working in congested health systems in low-resource settings. Public investment in training programs for MAs and greater acceptance by physicians and patients will be essential for handling the growing burden associated with chronic illnesses like DM. Trained MAs may also play a role in improved patient education and awareness regarding diabetes self-management.

Impact of structured education on glucose control and hypoglycaemia in Type-2 diabetes: a systematic review of randomized controlled trials

Evidence for the use of structured education in diabetes management is accumulating and has shown positive influence in the management of Type-2 diabetes.

Objective

To assess the impact of structured education on glucose control and hypoglycaemia in the management of Type-2 diabetes.

Methods

A systematic review was done using Medline via Ovid and EMBASE databases of published English literature between 1980 and 2014. Included studies were randomized control trials that assessed the impact of structured education on glucose control and hypoglycaemia.

Results

Out of the 12,086 full text articles were identified, 36 full text articles were finally considered for this review after applying both inclusion and exclusion criteria, of which 34 were exclusively on the effect of structured diabetes education on glucose control whilst 2 were studies on the effects of structured diabetes education on glucose control and hypoglycaemia. Majority of the studies included a predominant Caucasian population. There was heterogeneity in the included studies such as intervention methods and intensity as well as follow up periods. Group based education was preferred over individual education by most studies. Overall, most of the studies showed a significant positive effect on glycaemic control compared with control groups. One study showed a significant impact of structured education on hypoglycaemia.

Conclusion

Structured education has positive impact on glucose control and hypoglycaemia in Type-2 diabetes and must be incorporated in routine care.

Funding

The study was funded by the authors.

Comparative effectiveness of telemedicine strategies on type 2 diabetes management: A systematic review and network meta-analysis

The effects of telemedicine strategies on the management of diabetes is not clear. This study aimed to investigate the impact of different telemedicine strategies on glycaemic control management of type 2 diabetes patients. A search was performed in 6 databases from inception until September 2016 for randomized controlled studies that examined the use of telemedicine in adults with type 2 diabetes. Studies were independently extracted and classified according to the following telemedicine strategies: teleeducation, telemonitoring, telecase-management, telementoring and teleconsultation. Traditional and network meta-analysis were performed to estimate the relative treatment effects. A total of 107 studies involving 20,501 participants were included. Over a median of 6 months follow-up, telemedicine reduced haemoglobin A1c (HbA1c) by a mean of 0.43% (95% CI: −0.64% to −0.21%). Network meta-analysis showed that all telemedicine strategies were effective in reducing HbA1c significantly compared to usual care except for telecase-management and telementoring, with mean difference ranging from 0.37% and 0.71%. Ranking indicated that teleconsultation was the most effective telemedicine strategy, followed by telecase-management plus telemonitoring, and finally teleeducation plus telecase-management. The review indicates that most telemedicine strategies can be useful, either as an adjunct or to replace usual care, leading to clinically meaningful reduction in HbA1c.

The effect of nurse prescribers on glycaemic control in type 2 diabetes: A systematic review and meta-analysis

BACKGROUND

The creation of advanced nursing roles in diabetes management, with specific skills such as nurse prescribing, has resulted in nurses taking on roles that have traditionally been associated with doctors.

OBJECTIVES

We aimed to examine the effectiveness of nurse-led clinics, in which nurses were involved in prescribing, on haemoglobin A1c (HbA1c) among people with type 2 diabetes.

METHODS

We systematically searched the literature, Medline, the Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE and Allied Health Literature database guide (CINAHL) databases, to identify randomised controlled trials (RCTs) assessing the effect of nurse prescribers on HbA1c. We focused on randomised controlled trials which compared nurse prescriber interventions with usual care in adults aged 18 years or over with a diagnosis of type 2 diabetes. The main outcome measure was change in HbA1c levels. We performed a random effects model meta-analysis to assess the pooled effect size of the intervention. Studies were divided into two groups according to the role of nurses in the intervention. In one group, the nurses supplemented a team, as an add-on to usual care; in the other group, they worked independently, and were compared directly to a doctor.

RESULTS

Nine RCTs were identified and included in this study. All studies were from developed countries, with a medium risk of bias and a moderate heterogeneity between studies. In the five RCTs in which nurse prescribers supplemented a team, there was no significant difference in change of HbA1c compared to usual care (-0.34 percentage points; 95% CI: -0.71, 0.02). In the four RCTs in which nurses replaced doctors, the outcomes of nurse prescribers were comparable to those of doctors. No data on adverse events were available.

CONCLUSION

There was no clear evidence of benefit on glycaemic control, when nurses who undertake prescribing work alongside a doctor and other practitioners. However, in those studies in which nurses replaced physicians, the glycaemic control was comparable between nurses and doctors. Therefore, there may be value in providing nurse-led prescribing services where there is limited access to doctor-led services.

Randomized Controlled Trial of Technology-Assisted Case Management in Low Income Adults with Type 2 Diabetes

OBJECTIVE

To assess the efficacy of technology-assisted case management (TACM) with medication titration by nurses using guideline-based algorithms, under physician supervision in improving glycemic control in low-income rural adults with poorly controlled type 2 diabetes.

RESEARCH DESIGN AND METHODS

Adults (aged ≥18 years) from the southeastern United States with hemoglobin A1c [HbA1c] ≥8% were randomized to TACM or usual care. Evidence-based guidelines were used to develop medication titration algorithms in conjunction with clinic physicians. Participants were given a telehealth device that uploaded blood glucose and blood pressure readings daily to a central server. A nurse case manager was trained on the algorithms and authorized to titrate medications every 2 weeks based on the algorithm under the supervision of an internist and an endocrinologist. Participants were assessed at baseline, 3 months, and 6 months. The primary outcome was HbA1c at 6-months postrandomization in the intent-to-treat (ITT) population.

RESULTS

One hundred thirteen participants were randomized to either TACM intervention or usual care. Based on ITT population after multiple imputation, the analysis of covariance with baseline HbA1c as covariate showed that HbA1c at 6 months for TACM was significantly lower compared to the usual care group (-0. 99, P = 0.024). Moreover, longitudinal mixed effects analysis suggested that the rate of decline in HbA1c over time for TACM was significantly faster compared to the usual care group (-0.16, P = 0.038). Results based on per-protocol population were similar.

CONCLUSIONS

Technology-assisted case management by a nurse with medication titration under physician supervision is efficacious in improving glycemic control in low-income rural adults with poorly controlled type 2 diabetes.

US Nurses’ Perceptions of Their Role in Diabetes Care

PURPOSE

The purpose of this study was to examine nurse and physician perceptions of nurse involvement and roles in diabetes care.

METHODS

The study used a cross-sectional design with face-to-face or telephone interviews of diabetes health care professionals in 13 countries from Asia, Australia, Europe, and North America. This article focuses on the data from US health care providers. The US sample included 51 generalist nurses, 50 diabetes specialist nurses, 166 generalist physicians, and 50 diabetes specialist physicians.

RESULTS

Nurses and physicians agreed that nurses should take a larger role in managing diabetes. Most common differences identified between nurses and physicians were that nurses provide better education, spend more time with patients, were better listeners, and knew their patients better than physicians. All nurses had a high perceived need for better understanding of psychosocial issues and were more likely than physicians to suggest helping patients to take responsibility for their care. Nurses more than physicians also said better communication was needed. Generalist nurses report that they act as intermediaries and facilitate patient appointment keeping. Specialist nurses talk to patients about self-management, teach medication management, have a higher level of involvement in medication prescribing, and are more willing to take on additional responsibilities than generalist nurses.

CONCLUSIONS

There is an increased need for more involvement by nurses, particularly specialist nurses, in diabetes care.

Clinical Inertia Contributes to Poor Diabetes Control in a Primary Care Setting

Purpose

The purpose of this study was to determine whether “clinical inertia”—inadequate intensification of therapy by the provider—could contribute to high A1C levels in patients with type 2 diabetes managed in a primary care site.

Methods

In a prospective observational study, management was compared in the Medical Clinic, a primary care site supervised by general internal medicine faculty, and the Diabetes Clinic, a specialty site supervised by endocrinologists. These municipal hospital clinics serve a common population that is largely African American, poor, and uninsured.

Results

Four hundred thirty-eight African American patients in the Medical Clinic and 2157 in the Diabetes Clinic were similar in average age, diabetes duration, body mass index, and gender, but A1C averaged 8.6% in the Medical Clinic versus 7.7% in the Diabetes Clinic (P < .0001). Use of pharmacotherapy was less intensive in the Medical Clinic (less use of insulin), and when patients had elevated glucose levels during clinic visits, therapy was less than half as likely to be advanced in the Medical Clinic compared to the Diabetes Clinic (P < .0001). Intensification rates were lower in the Medical Clinic regardless of type of therapy (P < .0001), and intensification of therapy was independently associated with improvement in A1C (P < .001).

Conclusions

Medical Clinic patients had worse glycemic control, were less likely to be treated with insulin, and were less likely to have their therapy intensified if glucose levels were elevated. To improve diabetes management and glycemic control nationwide, physicians in training and generalists must learn to overcome clinical inertia, to intensify therapy when appropriate, and to use insulin when clinically indicated.

Feasibility and Effectiveness of System Redesign for Diabetes Care Management in Rural Areas

Purpose

Redesigning the system of care for the management of patients with type 2 diabetes mellitus has not been well studied in rural communities with a significant minority population and limited health care resources. This study assesses the feasibility and potential for cost-effectiveness of restructuring care in rural fee-for-service practices for predominantly minority patients with diabetes mellitus.

Methods

This was a feasibility study of implementing case management, group visits, and electronic registry in 5 solo or small group primary care practices in rural North Carolina. The subjects were 314 patients with type 2 diabetes mellitus (mean age = 61 years; 72% African American; 54% female). An advanced practice nurse visited each practice weekly for 12 months, provided intensive diabetes case management, and facilitated a 4-session group visit educational program. An electronic diabetes registry and visit reminder systems were implemented.

Results

There was an improvement in the percentage of patients achieving diabetes management goals and an improvement in productivity and billable encounters. The percentage of patients with a documented self-management goal increased from 0% to 42%, a currently documented lipid panel from 55% to 76%, currently documented aspirin use from 25% to 37%, and currently documented foot examination from 12% to 54%. The average daily encounter rate improved from 20.17 to 31.55 on intervention days.

Conclusions

A redesigned care delivery system that uses case management with structured group visits and an electronic registry can be successfully incorporated into rural primary care practices and appears to significantly improve both care processes and practice productivity.

Non-medical prescribing versus medical prescribing for acute and chronic disease management in primary and secondary care

BACKGROUND

A range of health workforce strategies are needed to address health service demands in low-, middle- and high-income countries. Non-medical prescribing involves nurses, pharmacists, allied health professionals, and physician assistants substituting for doctors in a prescribing role, and this is one approach to improve access to medicines.

OBJECTIVES

To assess clinical, patient-reported, and resource use outcomes of non-medical prescribing for managing acute and chronic health conditions in primary and secondary care settings compared with medical prescribing (usual care).

SEARCH METHODS

We searched databases including CENTRAL, MEDLINE, Embase, and five other databases on 19 July 2016. We also searched the grey literature and handsearched bibliographies of relevant papers and publications.

SELECTION CRITERIA

Randomised controlled trials (RCTs), cluster-RCTs, controlled before-and-after (CBA) studies (with at least two intervention and two control sites) and interrupted time series analysis (with at least three observations before and after the intervention) comparing: 1. non-medical prescribing versus medical prescribing in acute care; 2. non-medical prescribing versus medical prescribing in chronic care; 3. non-medical prescribing versus medical prescribing in secondary care; 4 non-medical prescribing versus medical prescribing in primary care; 5. comparisons between different non-medical prescriber groups; and 6. non-medical healthcare providers with formal prescribing training versus those without formal prescribing training.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. Two review authors independently reviewed studies for inclusion, extracted data, and assessed study quality with discrepancies resolved by discussion. Two review authors independently assessed risk of bias for the included studies according to EPOC criteria. We undertook meta-analyses using the fixed-effect model where studies were examining the same treatment effect and to account for small sample sizes. We compared outcomes to a random-effects model where clinical or statistical heterogeneity existed.

MAIN RESULTS

We included 46 studies (37,337 participants); non-medical prescribing was undertaken by nurses in 26 studies and pharmacists in 20 studies. In 45 studies non-medical prescribing as a component of care was compared with usual care medical prescribing. A further study compared nurse prescribing supported by guidelines with usual nurse prescribing care. No studies were found with non-medical prescribing being undertaken by other health professionals. The education requirement for non-medical prescribing varied with country and location.A meta-analysis of surrogate markers of chronic disease (systolic blood pressure, glycated haemoglobin, and low-density lipoprotein) showed positive intervention group effects. There was a moderate-certainty of evidence for studies of blood pressure at 12 months (mean difference (MD) -5.31 mmHg, 95% confidence interval (CI) -6.46 to -4.16; 12 studies, 4229 participants) and low-density lipoprotein (MD -0.21, 95% CI -0.29 to -0.14; 7 studies, 1469 participants); we downgraded the certainty of evidence from high due to considerations of serious inconsistency (considerable heterogeneity), multifaceted interventions, and variable prescribing autonomy. A high-certainty of evidence existed for comparative studies of glycated haemoglobin management at 12 months (MD -0.62, 95% CI -0.85 to -0.38; 6 studies, 775 participants). While there appeared little difference in medication adherence across studies, a meta-analysis of continuous outcome data from four studies showed an effect favouring patient adherence in the non-medical prescribing group (MD 0.15, 95% CI 0.00 to 0.30; 4 studies, 700 participants). We downgraded the certainty of evidence for adherence to moderate due to the serious risk of performance bias. While little difference was seen in patient-related adverse events between treatment groups, we downgraded the certainty of evidence to low due to indirectness, as the range of adverse events may not be related to the intervention and selective reporting failed to adequately report adverse events in many studies.Patients were generally satisfied with non-medical prescriber care (14 studies, 7514 participants). We downgraded the certainty of evidence from high to moderate due to indirectness, in that satisfaction with the prescribing component of care was only addressed in one study, and there was variability of satisfaction measures with little use of validated tools. A meta-analysis of health-related quality of life scores (SF-12 and SF-36) found a difference favouring usual care for the physical component score (MD 1.17, 95% CI 0.16 to 2.17), but not the mental component score (MD 0.58, 95% CI -0.40 to 1.55). However, the quality of life measurement may more appropriately reflect composite care rather than the prescribing component of care, and for this reason we downgraded the certainty of evidence to moderate due to indirectness of the measure of effect. A wide variety of resource use measures were reported across studies with little difference between groups for hospitalisations, emergency department visits, and outpatient visits. In the majority of studies reporting medication use, non-medical prescribers prescribed more drugs, intensified drug doses, and used a greater variety of drugs compared to usual care medical prescribers.The risk of bias across studies was generally low for selection bias (random sequence generation), detection bias (blinding of outcome assessment), attrition bias (incomplete outcome data), and reporting bias (selective reporting). There was an unclear risk of selection bias (allocation concealment) and for other biases. A high risk of performance bias (blinding of participants and personnel) existed.

AUTHORS' CONCLUSIONS

The findings suggest that non-medical prescribers, practising with varying but high levels of prescribing autonomy, in a range of settings, were as effective as usual care medical prescribers. Non-medical prescribers can deliver comparable outcomes for systolic blood pressure, glycated haemoglobin, low-density lipoprotein, medication adherence, patient satisfaction, and health-related quality of life. It was difficult to determine the impact of non-medical prescribing compared to medical prescribing for adverse events and resource use outcomes due to the inconsistency and variability in reporting across studies. Future efforts should be directed towards more rigorous studies that can clearly identify the clinical, patient-reported, resource use, and economic outcomes of non-medical prescribing, in both high-income and low-income countries.

Adverse safety events in patients with Chronic Kidney Disease (CKD)

INTRODUCTION

Chronic kidney disease (CKD) confers a higher risk of adverse safety events as a result of many factors including medication dosing errors and use of nephrotoxic drugs, which can cause kidney injury and renal function decline. CKD patients may also have comorbidities such as hypertension and diabetes for which they require more frequent care from different providers, and for which standard, but countervailing treatments, may put them at risk for adverse safety events. Areas covered: In addition to the well-known agents such as iodinated radiocontrast, antimicrobials, diuretics and angiotensin converting enzyme (ACE) inhibitors which can directly affect renal function, safety considerations in the treatment of common CKD complications such as anemia, diabetes, analgesia and thrombosis will also be discussed. Expert opinion: Better outcomes in CKD may be achieved by alerting care providers to the special care needs of kidney patients and encouraging patients to self-manage their disease with the decision support of multidisciplinary patient care teams.

Intervention for Diabetes with Education, Advancement and Support (IDEAS) study: protocol for a cluster randomised controlled trial

BACKGROUND

The high market penetration of mobile phones has triggered an opportunity to combine mobile technology with health care to overcome challenges in today's health care setting. Although Malaysia has a high Internet and mobile penetration rate, evaluations of the efficacy of incorporating this technology in diabetes care is not common. We report the development of a telemonitoring coaching system, using the United Kingdom (UK) Medical Research Council (MRC) framework, for patients with type 2 diabetes mellitus.

METHODS

The Intervention for Diabetes with Education, Technological Advancement and Support (IDEAS) study is a telemonitoring programme based on an empowerment philosophy to enable participants to be responsible for their own health decision and behaviour. An iterative cycle of development, piloting, and collating qualitative and quantitative data will be used to inform and refine the intervention. To increase compliance, the intervention will be designed to encourage self-management using simple, non-technical knowledge. The primary outcomes will be HbA1c, blood pressure, total cholesterol, and quality of life and diabetes self-efficacy. In addition, an economic analysis on health service utilisation will be collected.

DISCUSSION

The mixed-method approach in this study will allow for a holistic overview of using telemonitoring in diabetes care. This design enables researchers to understand the effectiveness of telemonitoring as well as provide insights towards the receptiveness of incorporating information technology amongst type 2 diabetes patients in a community setting.

The cost-effectiveness of hospital-based telephone coaching for people with type 2 diabetes: a 10 year modelling analysis

BACKGROUND

Type 2 diabetes (T2DM) is a burdensome condition for individuals to live with and an increasingly costly condition for health services to treat. Cost-effective treatment strategies are required to delay the onset and slow the progression of diabetes related complications. The Diabetes Telephone Coaching Study (DTCS) demonstrated that telephone coaching is an intervention that may improve the risk factor status and diabetes management practices of people with T2DM. Measuring the cost effectiveness of this intervention is important to inform funding decisions that may facilitate the translation of this research into clinical practice. The purpose of this study is to assess the cost-effectiveness of telephone coaching, compared to usual diabetes care, in participants with poorly controlled T2DM.

METHODS

A cost utility analysis was undertaken using the United Kingdom Prospective Diabetes Study (UKPDS) Outcomes Model to extrapolate outcomes collected at 6 months in the DTCS over a 10 year time horizon. The intervention's impact on life expectancy, quality-adjusted life expectancy (QALE) and costs was estimated. Costs were reported from a health system perspective. A 5 % discount rate was applied to all future costs and effects. One-way sensitivity analyses were conducted to reflect uncertainty surrounding key input parameters.

RESULTS

The intervention dominated the control condition in the base-case analysis, contributing to cost savings of $3327 per participant, along with non-significant improvements in QALE (0.2 QALE) and life expectancy (0.3 years).

CONCLUSIONS

The cost of delivering the telephone coaching intervention continuously, for 10 years, was fully recovered through cost savings and a trend towards net health benefits. Findings of cost savings and net health benefits are rare and should prove attractive to decision makers who will determine whether this intervention is implemented into clinical practice.

The Role of Physicians and Certification Boards to Improve Quality

Amid growing focus on individual physician performance, it is timely to examine what evidence exists that physicians can be facilitators and leaders for health care quality improvement in their local health care environments. Despite the importance of governmental policy and national initiatives, change in health care quality must occur in the context of local communities. Therefore, individual physician involvement, working with other local health care leaders and providers, will be crucial to future quality improvement. The objectives of this article are as follows: (1) outline why physicians must be involved in quality improvement, (2) delineate the barriers and facilitators to physician involvement, and (3) discuss how medical certification boards can facilitate greater physician involvement in quality improvement.

The Rate and Cost of Hospital Readmissions for Preventable Conditions

The study estimates the rate and cost of preventable readmissions within 6 months after a first preventable admission, by age-group, and by payer and race within age-group. The descriptive results are contrasted with several hypotheses. The hospital discharge data are for residents of New York, Pennsylvania, Tennessee, and Wisconsin in 1999, from files of the Healthcare Cost and Utilization Project of the Agency for Healthcare Research and Quality. About 19 percent of persons with an initial preventable admission had at least one preventable readmission rate within 6 months. Hospital cost for preventable readmissions during 6 months was about $730 million. There were substantial differences in readmission rates by payer group and by race. Some evidence suggests that preventable readmissions may partly reflect complexity of underlying problems. Interventions to reduce cost might focus on identifying high-risk patients before discharge and devising new approaches to follow-up.

Organization of care for persons with HIV-infection: a systematic review

The objective of this systematic review was to examine the effectiveness of the organization of care: case management, multidisciplinary care, multi-faceted treatment, hours of service, outreach programs and health information systems on medical, immunological, virological, psychosocial and economic outcomes for persons living with HIV/AIDS. We searched PubMed (MEDLINE) and 10 other electronic databases from 1 January 1980 to April, 2012 for both experimental and controlled observational studies. Thirty-three studies met the inclusion criteria. Eleven studies were randomized controlled trials (RCTs), three of which were conducted in low-middle income settings. Patient characteristics, study design, organization measures and outcomes data were abstracted independently by two reviewers from all studies. A risk of bias tool was applied to RCTs and a separate tool was used to assess the quality of observational studies. This review concludes that case management interventions were most consistently associated with improvements in immunological outcomes but case management demonstrates no clear association with other outcome measures. The same mixed results were also identified for multidisciplinary and multi-faceted care interventions. Eight studies with an outreach intervention were identified and demonstrated improvements or non-inferiority with respect to mortality, receipt of antiretroviral medications, immunological outcomes, improvements in healthcare utilization and lower reported healthcare costs when compared to usual care. Of the interventions examined in this review, sustained in-person case management and outreach interventions were most consistently associated with improved medical and economic outcomes, in particular antiretroviral prescribing, immunological outcomes and healthcare utilization. No firm conclusions can be reached about the impact of any one intervention on patient mortality.

Chronic Care Initiatives for the Elderly: Can They Bridge the Gerontology-Medicine Gap?

The authors describe initiatives designed to meet the chronic health needs of the elderly. These programs include demonstration programs such as Program of All-Inclusive Care for Elderly, Social Health Maintenance Organization, and state programs for Medicare-Medicaid-eligible elders that focus on integrating medical care with home and community-based services, disease- or disability-focused care management/coordination initiatives, and recent population-based disease management programs focused on improving adherence to evidence-based protocols, self-care management, and the use of innovative practices such as group visits to improve health outcomes. These initiatives have the potential to improve outcomes and reduce costs, but also highlight tensions between medical model disease management and functionally oriented home and community service programs. The authors suggest that optimal chronic care for elders would require the integration of advances in medically oriented disease management with the best of home and community-based service programs. Medicare policy should promote such integration.

Outpatient diabetes clinical decision support: current status and future directions

Outpatient clinical decision support systems have had an inconsistent impact on key aspects of diabetes care. A principal barrier to success has been low use rates in many settings. Here, we identify key aspects of clinical decision support system design, content and implementation that are related to sustained high use rates and positive impacts on glucose, blood pressure and lipid management. Current diabetes clinical decision support systems may be improved by prioritizing care recommendations, improving communication of treatment-relevant information to patients, using such systems for care coordination and case management and integrating patient-reported information and data from remote devices into clinical decision algorithms and interfaces.

Searching for a Role of Nursing Personnel in Developing Landscape of Ehealth: Factors Determining Attitudes toward Key Patient Empowering Applications

Introduction

Nurses may play an important role in the delivery of medical services based on the use of ehealth tools. Nevertheless, their taking an active role in an ehealth environment depends on their possessing the appropriate skills and mindset. The main objective of this paper was to assess nurses’ opinions and to analyze the predictors of their acceptance of ehealth features relevant to patient empowerment with a strong focus on chronic care.

Methods

A survey was conducted among nurses from hospital centers of south-eastern Poland based on a questionnaire designed to assess their attitudes toward the ehealth domain. The predictors of the nurses’ acceptance of ehealth usage within specific contexts were assessed with uni- and multivariate logistic regression.

Results

An analysis was performed on data from 648 questionnaires retained after a quality check. The duration of Internet use was consistently related to higher acceptance of ehealth applications and more certainty regarding the reliability of health-related information available on the Internet. Nurses from urban medical centers were more skeptical about the use of specific ehealth solutions.

Conclusion

Previous experience in using information technologies is the main factor influencing the acceptance of specific ehealth solutions relevant for care provided to patients suffering from chronic conditions.

Application of integrative information system improves the quality and effectiveness of cancer case management

Cancer case management provides consecutive care during the entire process through diagnosis to treatment and follow-up. We established an integrative information system with integration of the health information system. This integrative information system shortened the time spent on case screening, follow-up data management, and monthly data summarization of case managers. It also promoted the case follow-up rate. This integrative information system may improve the quality and effectiveness for cancer case management, one important part of cancer nursing.
