Highlights The type of authority ordering precautionary measures affects compliance. Citizens are more likely to comply with costly measures when health risks are high. Citizens are more likely to comply with authorities they view as having expertise. Policymakers should provide expert-backed advice to increase compliance. Policymakers should take measures to make compliance less costly.

Haematoma after thyroid surgery can lead to airway obstruction and death. We therefore developed guidelines to improve the safety of peri-operative care of patients undergoing thyroid surgery. We conducted a systematic review to inform recommendations, with expert consensus used in the absence of high-quality evidence, and a Delphi study was used to ratify recommendations. We highlight the importance of multidisciplinary team management and make recommendations in key areas including: monitoring; recognition; post-thyroid surgery emergency box; management of suspected haematoma following thyroid surgery; cognitive aids; posthaematoma evacuation care; day-case thyroid surgery; training; consent and pre-operative communication; postoperative communication; and institutional policies. The guidelines support a multidisciplinary approach to the management of suspected haematoma following thyroid surgery through oxygenation and evaluation; haematoma evacuation; and tracheal intubation. They have been produced with materials to support implementation. While these guidelines are specific to thyroid surgery, the principles may apply to other forms of neck surgery. These guidelines and recommendations provided are the first in this area and it is hoped they will support multidisciplinary team working, improving care and outcomes for patients having thyroid surgery.

Does foreign aid enable or constrain elite capture of public revenues? Reflecting on prominent debates in the foreign aid literature, we examine whether recipient preferences are consistent with a view that foreign donors wield substantial control over the flow of aid dollars, making elite capture more difficult and mass benefits more likely. We compare elite and mass support for foreign aid versus government spending on development projects through a survey experiment with behavioral outcomes. A key innovation is a parallel experiment on members of the Ugandan national parliament and a representative sample of Ugandan citizens. For two actual aid projects, we randomly assigned different funders to the projects. Significant treatment effects reveal that members of parliament support government programs over foreign aid, whereas citizens prefer aid over government. Donor control also implies that citizens should favor foreign aid more and elites less as their perceptions of government clientelism and corruption increase. We explore this and report on other alternative mechanisms. Effects for citizens and elites are most apparent for those perceiving significant government corruption, suggesting that both sets of subjects perceive significant donor control over aid.3

PHM is associated with increased risk of major resection at revision. The pattern of failure was not different in patients with hiatal mesh, suggesting that hiatal mesh does not eliminate the potential for revision. When performing hiatal herniorrhaphy, the increased risk of recurrence without mesh must be weighed against the potential risk for subsequent major resection when using mesh.
