Enhancing evidence informed policymaking in complex health systems: lessons from multi-site collaborative approaches.

BACKGROUND: There is an increasing interest worldwide to ensure evidence-informed health policymaking as a means to improve health systems performance. There is a need to engage policymakers in collaborative approaches to generate and use knowledge in real world settings. To address this gap, we implemented two interventions based on iterative exchanges between researchers and policymakers/implementers. This article aims to reflect on the implementation and impact of these multi-site evidence-to-policy approaches implemented in low-resource settings. METHODS: The first approach was implemented in Mexico and Nicaragua and focused on implementation research facilitated by communities of practice (CoP) among maternal health stakeholders. We conducted a process evaluation of the CoPs and assessed the professionals' abilities to acquire, analyse, adapt and apply research. The second approach, called the Policy BUilding Demand for evidence in Decision making through Interaction and Enhancing Skills (Policy BUDDIES), was implemented in South Africa and Cameroon. The intervention put forth a 'buddying' process to enhance demand and use of systematic reviews by sub-national policymakers. The Policy BUDDIES initiative was assessed using a mixed-methods realist evaluation design. RESULTS: In Mexico, the implementation research supported by CoPs triggered monitoring by local health organizations of the quality of maternal healthcare programs. Health programme personnel involved in CoPs in Mexico and Nicaragua reported improved capacities to identify and use evidence in solving implementation problems. In South Africa, Policy BUDDIES informed a policy framework for medication adherence for chronic diseases, including both HIV and non-communicable diseases. Policymakers engaged in the buddying process reported an enhanced recognition of the value of research, and greater demand for policy-relevant knowledge. CONCLUSIONS: The collaborative evidence-to-policy approaches underline the importance of iterations and continuity in the engagement of researchers and policymakers/programme managers, in order to account for swift evolutions in health policy planning and implementation. In developing and supporting evidence-to-policy interventions, due consideration should be given to fit-for-purpose approaches, as different needs in policymaking cycles require adapted processes and knowledge. Greater consideration should be provided to approaches embedding the use of research in real-world policymaking, better suited to the complex adaptive nature of health systems.

The Cotton Osteotomy as an Adjunct Procedure in Hallux Valgus and Hallux Limitus Surgery.

The Cotton osteotomy, as described in 1936 by Frederic Cotton, consisted of a medial cuneiform opening base wedge osteotomy. This Cotton osteotomy served to restore the "triangle of support" of the foot. In his address to the New England Surgical Society, he described this osteotomy as being multipurpose; it can be used for plantarflexion in hallux valgus surgery and has use in hallux rigidus conditions. Since its inception, the procedure has become a popular adjunct to aid in the restoration of the medial column deformity present in pes planus. Recently, there has been renewed interest in the use of the procedure to aid in the correction of deformities involving metatarsus primus elevatus, specifically, hallux valgus and hallux limitus. The advantage of the use of this procedure as opposed to others is that it allows for the preservation and/or restoration of first ray length and the preservation of motion at the medial column. In retrospective review, the authors evaluated seven cases with a 1-year follow-up. In this series of cases, the Cotton osteotomy was performed as an adjunct to common hallux valgus procedures or hallux limitus corrections. Radiographic review was also performed evaluating for initial evidence of radiographic bone-graft healing and patient weightbearing. Although not without its own limitations, the Cotton osteotomy offers several advantages with minimal complications, proving to be a valuable underused resource in the foot and ankle surgeon's toolkit.

Bilateral symptomatic Pacinian corpuscle hyperplasia of the adult foot.

Pacinian hyperplasia in the human body has been rarely described in the literature with most cases reported involving the hand (Fassola et al., 2019). This hyperplasia is considered a reactive lesion as opposed to a neoplasm (Satge et al., 2001), with the most common presenting complaint being pain and swelling (Fassola et al., 2019). In this study, a case of bilateral Pacinian corpuscle hyperplasia in the adult foot not previously described in the literature is presented.
