Which incentive package will retain regionalized health personnel in Burkina Faso: a discrete choice experiment

Background

The lack of motivation of health workers to practice in rural areas remains a crucial problem for decision-makers, as it deprives the majority of access to health care. To solve the problem, many countries have implemented health worker retention strategies. However, the development of such strategies requires an understanding of the preferences of health workers. The objective of the study was to identify a package for attracting and retaining health workers in underserved areas.

Methods

A cross sectional study was conducted in three health regions of Burkina Faso in 2012. A discrete choice experiment was used to investigate preferences for incentive packages among health workers recruited under the regionalized policy. In-depth interviews and focus group discussions with health workers currently working in the East and Sahel regions and policy makers, and a literature review on attraction and retention in low income countries, were performed to identify the attributes and levels. These attributes were: the regionalized recruitment policy, health insurance, work equipment, housing, and specific incentive compensation. The final design resulted in 16 choice sets. A multinomial logistic regression was used to determine the influence of socio-demographic characteristics on choice of a given option. A probit logistic regression model was then used to analyze the effect of these difference variables on choice, to identify the incentive package best suited to health workers. In total, questionnaires were administered to 315 regional health workers.

Results

For all participants, choice of package was strongly influenced by length of commitment under the policy and provision of housing. Sex, number of years in profession, and location also influenced the choice of package. Women are twice more likely to choose a package with free housing and the cancellation of the policy.

Conclusion

It is important that governments consider health worker preferences in crafting policies to address attraction and retention in underserved areas. In addition, the methodology of discrete choice experiment has been particularly useful, not only for better understanding the factors explaining the reluctance of health workers to work in underserved areas, but also to provide practical advice to the government, to improve its retention policy.

     

Quantitative and Volumetric European Association for the Study of the Liver and Response Evaluation Criteria in Solid Tumors Measurements: Feasibility of a Semiautomated Software Method to Assess Tumor Response after Transcatheter Arterial Chemoembolization

PurposeTo show that hepatic tumor volume and enhancement pattern measurements can be obtained in a time-efficient and reproducible manner on a voxel-by-voxel basis to provide a true three-dimensional (3D) volumetric assessment.Materials and MethodsMagnetic resonance (MR) imaging data obtained from 20 patients recruited for a single-institution prospective study were retrospectively evaluated. All patients had a diagnosis of hepatocellular carcinoma (HCC) and underwent drug-eluting beads (DEB) transcatheter arterial chemoembolization for the first time. All patients had undergone contrast-enhanced MR imaging before and after DEB transcatheter arterial chemoembolization; poor image quality excluded 3 patients, resulting in a final count of 17 patients. Volumetric RECIST (vRECIST) and quantitative EASL (qEASL) were measured, and segmentation and processing times were recorded.ResultsThere were 34 scans analyzed. The time for semiautomatic segmentation was 65 seconds±33 (range, 40–200 seconds). vRECIST and qEASL of each tumor were computed<1 minute for each.ConclusionsSemiautomatic quantitative tumor enhancement (qEASL) and volume (vRECIST) assessment is feasible in a workflow-efficient time frame. Clinical correlation is necessary, but vRECIST and qEASL could become part of the assessment of intraarterial therapy for interventional radiologists.     

Refractory bleeding from gastroduodenal ulcers: arterial embolization in high-operative-risk patients

GOALS AND BACKGROUND: We evaluated the efficacy and medium-term outcomes of transcatheter embolization to control massive bleeding from gastroduodenal ulcers after failed endoscopic treatment in high-operative-risk patients. STUDY: Retrospective study of 35 consecutive emergency embolization procedures in hemodynamically unstable patients (24 men, 11 women, mean age 71+/-11.6 y) referred from 1999 to 2006 for selective angiography after failed endoscopic treatment. Mean follow-up was 27 months. RESULTS: Endovascular treatment was feasible in 33 patients and consistently stopped the bleeding. "Sandwich" coiling of the gastroduodenal artery was performed in 11 patients and superselective occlusion of the terminal feeding artery with glue, coils, or gelatine particles in 22 patients. Early rebleeding occurred in 6 patients and was managed successfully using endoscopy (n=2), reembolization (n=1), or surgery (n=3). No major complications related to catheterization occurred. Seven patients died within 30 days of embolization and 3 died later during the follow-up, but none of the deaths were due to rebleeding. No late bleeding recurrences were reported. CONCLUSIONS: Selective angiographic embolization is safe and effective for controlling life-threatening bleeding from gastroduodenal ulcers, usually obviating the need for emergency surgery in critically ill patients, whose immediate survival depends on their underlying conditions.     

Management of duodenal ulcer bleeding resistant to endoscopy:Surgery is dead!

Acute massive duodenal bleeding is one of the most frequent complications of peptic ulcer disease.Endoscopy is the first-line method for diagnosing and treating actively bleeding peptic ulcers because its success rate is high.Of the small group of patients whose bleeding fails to respond to endoscopic therapy,increasingly the majority is referred for embolotherapy.Indeed,advances in catheter-based techniques and newer embolic agents,as well as recognition of the effectiveness of minimally invasive treatment options,have expanded the role of interventional radiology in the management of hemorrhage from peptic ulcers over the past decade.Embolization may be effective for even the most gravely ill patients for whom surgery is not a viable option,even when extravasation is not visualized by angiography.However,it seems that careful selection of the embolic agents according to the bleeding vessel may play a role in a successful outcome.The role of the surgeon in this clinical sphere is dramatically diminishing and will certainly continue to diminish in ensuing years,surgery being typically reserved for patients whose bleeding failed to respond all previous treatments.Such a setting has become extremely rare.     

CT analysis of the aorta in giant-cell arteritis: a case-control study

Objectives

Giant cell arteritis (GCA) is a large-vessel vasculitis whose diagnosis is confirmed by temporal artery biopsy. However, involvement of large vessels, especially the aorta, can be shown by imaging, which plays an increasing role in GCA diagnosis. The threshold above which aortic wall thickening, as measured by computed tomography (CT), is considered pathological is controversial, with values ranging from 2 to 3 mm. This study assessed aortic morphology by CT scan and its diagnostic value in GCA.

Methods

Altogether, 174 patients were included (64 with GCA, 43 with polymyalgia rheumatica and 67 controls). All patients had a CT scan at diagnosis or at inclusion for controls. Aortic wall thickness, aortic diameter and scores for atheroma were measured. Assessor was blinded to each patient’s group.

Results

Aortic diameters and atheroma scores were similar between groups. Aortic wall thickness was greater in the GCA group, even after the exclusion of GCA patients with aortic wall thickness ≥3 mm. The receiver operating characteristic (ROC) curve showed that a wall thickness of 2.2 mm was the optimal threshold to diagnose GCA (sensitivity, 67%; specificity, 98%).

Conclusions

Measuring aortic wall thickness by CT scan is effective to diagnose GCA. The optimal threshold to regard aortic wall thickening as pathological was ≥2.2 mm.

Key points

? Imaging, including CT scan, plays an increasing role in GCA diagnosis? CT measurement of aortic wall thickness is useful to diagnose GCA? A 2.2-mm threshold allows the diagnosis of thickened aortic wall in GCA
