Strategies to adapt and implement health system guidelines and recommendations: a scoping review.

BACKGROUND: Evidence-based health system guidelines are pivotal tools to help outline the important financial, policy and service components recommended to achieve a sustainable and resilient health system. However, not all guidelines are readily translatable into practice and/or policy without effective and tailored implementation and adaptation techniques. This scoping review mapped the evidence related to the adaptation and implementation of health system guidelines in low- and middle-income countries. METHODS: We conducted a scoping review following the Joanna Briggs Institute methodology for scoping reviews. A search strategy was implemented in MEDLINE (Ovid), Embase, CINAHL, LILACS (VHL Regional Portal), and Web of Science databases in late August 2020. We also searched sources of grey literature and reference lists of potentially relevant reviews. All findings were reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews. RESULTS: A total of 41 studies were included in the final set of papers. Common strategies were identified for adapting and implementing health system guidelines, related barriers and enablers, and indicators of success. The most common types of implementation strategies included education, clinical supervision, training and the formation of advisory groups. A paucity of reported information was also identified related to adaptation initiatives. Barriers to and enablers of implementation and adaptation were reported across studies, including the need for financial sustainability. Common approaches to evaluation were identified and included outcomes of interest at both the patient and health system level. CONCLUSIONS: The findings from this review suggest several themes in the literature and identify a need for future research to strengthen the evidence base for improving the implementation and adaptation of health system guidelines in low- and middle-income countries. The findings can serve as a future resource for researchers seeking to evaluate implementation and adaptation of health system guidelines. Our findings also suggest that more effort may be required across research, policy and practice sectors to support the adaptation and implementation of health system guidelines to local contexts and health system arrangements in low- and middle-income countries.

Clinical Impact of Initiation of U-500 Insulin vs Continuation of U-100 Insulin in Subjects With Diabetes.

BACKGROUND: The prevalence of obesity and diabetes mellitus (DM) has each increased drastically according to the Centers for Disease Control and Prevention. Growth of severe insulinresistant DM is predicted. U-500 insulin is highly concentrated and can replace less concentrated formulations in patients that need high insulin dosages. The aim of this study was to compare clinical outcomes of U-500 and U-100 insulin regimens in veterans with obesity and insulin resistance. METHODS: A single-site retrospective chart analysis of adult subjects was conducted from July 2002 to June 2011. Data for repeated measures spanned a period from 3 months before the intervention (baseline) through 12 months afterward. The main outcome was the variation in hemoglobin A1c (HbA1c). Other outcomes included incidence of severe hypoglycemia, weight changes, cardiovascular events, and number of injections. RESULTS: A total of 142 subjects (68 taking U-500 and 74 taking U-100) were included. Baseline characteristics were similar between the groups, except for weight, which was higher among U-500 subjects. Mean HbA1c was reduced by 0.84% and 0.56% in U-500 and U-100, respectively (P = .003). Severe hypoglycemia occurred in 5 subjects in the U-500 group and 1 in the U-100 group (P = .08). No significant difference was noted in the number of cardiovascular events. The mean number of daily injections was 2 in the U-500 group, and 4 in the U-100 group (P < .001). CONCLUSIONS: U-500 insulin, when compared with U-100 insulin regimens, led to a statistically significant reduction in HbA1c and number of insulin injections. Additional research is necessary to assess the risk of severe hypoglycemia in U-500 users. Neither regimen was associated with increased cardiovascular risk.

A framework for explaining the role of values in health policy decision-making in Latin America: a critical interpretive synthesis.

BACKGROUND: Although values underpin the goals pursued in health systems, including how health systems benefit the population, it is often not clear how values are incorporated into policy decision-making about health systems. The challenge is to encompass social/citizen values, health system goals, and financial realities and to incorporate them into the policy-making process. This is a challenge for all health systems and of particular importance for Latin American (LA) countries. Our objective was to understand how and under what conditions societal values inform decisions about health system financing in LA countries. METHODS: A critical interpretive synthesis approach was utilised for this work. We searched 17 databases in December 2016 to identify articles written in English, Spanish or Portuguese that focus on values that inform the policy process for health system financing in LA countries at the macro and meso levels. Two reviewers independently screened records and assessed them for inclusion. One researcher conceptually mapped the included articles, created structured summaries of key findings from each, and selected a purposive sample of articles to thematically synthesise the results across the domains of agenda-setting/prioritisation, policy development and implementation. RESULTS: We identified 5925 references, included 199 papers, and synthesised 68 papers. We identified 116 values and developed a framework to explain how values have been used to inform policy decisions about financing in LA countries. This framework has four categories - (1) goal-related values (i.e. guiding principles of the health system); (2) technical values (those incorporated into the instruments adopted by policy-makers to ensure a sustainable and efficient health system); (3) governance values (those applied in the policy process to ensure a transparent and accountable process of decision-making); and (4) situational values (a broad category of values that represent competing strategies to make decisions in the health systems, their influence varying according to the four factors). CONCLUSIONS: It is an effort to consolidate and explain how different social values are considered and how they support policy decision-making about health system financing. This can help policy-makers to explicitly incorporate values into the policy process and understand how values are supporting the achievement of policy goals in health system financing.
