Complication Rates Following Total Ankle Arthroplasty in Inpatient versus Outpatient Populations: A Systematic Review & Meta-Analysis

Total ankle arthroplasty (TAA) is used as an alternative to ankle arthrodesis for adults with severe ankle arthritis. Numerous orthopedic centers have entered the healthcare market offering fast-tracked joint replacement protocols, meanwhile, TAA has been excluded from these joint centers, and is primarily performed in the inpatient setting. The purpose of this study is to examine short-term complications in the inpatient and outpatient settings following TAA using a systematic review and quantitative analysis. We considered all studies examining short-term complications following TAA performed in the inpatient versus outpatient setting occuring within 1 year of the index operation. We summarized data using a pooled relative risk and random effects model. A pooled sensitivity analysis was performed for studies with data on complication rates for inpatient or outpatient populations, which did not have a control group. The quality of included studies was assessed using the Cochrane risk of bias tool. Nine studies were included in the quantitative analysis, with 4 studies in the final meta-analysis. Subjects undergoing inpatient surgery experienced a 5-times higher risk of short-term complications compared to the outpatient group (risk ratio 5.27, 95% confidence interval 3.31, 8.42). Results did not change after sensitivity analysis (inpatient weighted mean complication rate: 9.62% vs outpatient weighted mean 5.02%, p value <.001). The overall level of evidence of included studies was level III, with a moderate to high risk of bias. Outpatient TAAs do not appear to pose excess complication risks compared to inpatient procedures, and may therefore be a reasonable addition to experienced centers that have established a fast-track outpatient total joint protocol.     

The use of third-party packed red blood cells during ex situ normothermic machine perfusion of organs for transplantation: Underappreciated complexities?

Ex situ normothermic machine perfusion (NMP) is being used increasingly in the assessment of higher risk deceased donor organs and to facilitate prolonged organ storage. Third-party packed red blood cells (pRBCs) are often used as an oxygen carrier in the perfusate of ex situ NMP. Despite the increasing interest in NMP, comparatively little attention has been paid to the appropriate selection of pRBCs. This includes the choice of ABO blood group and Rhesus D status, the need for special requirements for selected recipients, and the necessity for traceability of blood components. Flushing organs with cold preservation solution after NMP removes the overwhelming majority of third-party allogeneic pRBCs, but residual pRBCs within the organ may have biologically relevant effects following implantation as they enter the recipient's circulation. This review considers these issues, and suggests that national transplant and blood transfusion agencies work together to develop a co-ordinated approach within each country. This is especially important given the possibility of organ re-allocation between centers after ex situ NMP, and the ongoing development of organ perfusion hubs.     

Evaluation of the 2016–2020 regional tuberculosis response framework,WHO Western Pacific Region

ObjectiveTo assess the implementation of the Regional framework for action on implementation of the End TB Strategy in the Western Pacific, 2016–2020 in countries and areas in the World Health Organization Western Pacific Region.MethodsWe used a mixed methods approach to assess the framework’s measurable and perceived impact. We conducted an analysis of national tuberculosis strategic plans, a cross-sectional survey of senior staff of tuberculosis programmes, key informant interviews and some country case studies.FindingsOf the 37 countries and areas of the Western Pacific Region, 14 had a national tuberculosis strategic plan, including all countries and areas with a high incidence of tuberculosis. Most senior tuberculosis programme staff who responded to the survey (16/23) found the regional framework useful when developing their national targets and grant applications. Programmatic challenges identified included financing, human resources, public–private mix, active case finding, and paediatric and drug-resistant tuberculosis. Most of the 17 key informants thought that the regional framework’s categorization of actions (for all settings, for specific settings and for pre-elimination settings) was useful, but that the added value of the regional framework over other relevant documents was not obvious because of overlap in content.ConclusionThe regional framework influenced national level tuberculosis control planning and implementation in a positive way. A future regional framework should provide a longer-term strategic horizon and specifically address emerging trends and persistent problems faced by countries or areas of the region.

Use of refractometry to identify opioid-containing solutions

The purpose of this laboratory study was to assess the value of refractometry in identifying the contents of a variety of opioid-containing solutions. A hand-held refractometer was used to document the refraction produced by the undiluted contents of alfentanil, fentanyl, morphine, sufentanil ampoules and by solutions of Ringer’s lactate, 0.9% saline, 3.3% dextrose in 0.3% saline, and distilled water. Each opioid was then serially diluted in serial 1:2, 1:4, and 1:8 dilutions in each of these solutions and the refractions of each determined. Based on this information, blinded identification of various diluted opioid solutions was attempted. Refractometer values for undiluted fentanyl and sufentanil were identical with those for distilled water. Those for undiluted alfentanil and morphine were almost identical with each other and with 1:2 and 1:4 dilutions of either drug in Ringer’s lactate or 0.9% saline. We conclude that refractometry is an unreliable screening method to detect tampering with opioid solutions.
