Procedural Rates, Economic Costs, and Geographic Variation of Primary and Revision Lumbar Total Disc ReplacementWheeler, Anthony J. 01 August 2013 (has links)
Lumbar degenerative disc disease is a remarkably common condition among patients presenting with chronic low back pain and physical disability. When a surgical treatment option is warranted, patients now have the option of undergoing lumbar total disc replacement (TDR), a relatively new procedure that is designed to replace lumbar fusion, the traditional surgical intervention for degenerative disc disease. The lumbar TDR procedure has demonstrated clinical efficacy equivalent to that of lumbar fusion, although concern remains about the longevity, safety, and costs related to the procedure. These issues were addressed in three separate observational studies using administrative claims data. The first study estimated the revision burden and economic revision burden of lumbar TDR. The second study examined the lumbar TDR hybrid procedure, where both a lumbar TDR and lumbar fusion are performed simultaneously. No observational data have been reported on the frequency, cost, and diagnostic indications related to the TDR hybrid procedure. The third study mapped the geographic variation of procedural rates of lumbar TDR. Previous research has found substantial geographic variation in lumbar spine surgery rates and a similar analysis of lumbar TDR variation has yet to be reported. The present series of studies found the revision burden and economic revision burden of lumbar TDR to be similar to data reported for this procedure from the mid-2000s, though the overall occurrence of the procedure appears to have declined. The economic revision burden made this a lower-cost procedure than lumbar fusion, with a tradeoff in terms of revision burden being higher for lumbar TDR. The lumbar TDR hybrid procedure was found to make up approximately 16% of the total number of TDR procedures, involving much higher costs than a single-level TDR procedure. Finally, geographic variation of the procedural rate of lumbar TDR varied dramatically across the U.S., surpassing the variation observed in lumbar fusion surgery. Limitations of the observational data used in these studies are described. Recommendations for future observational research are offered as well. Finally, implications for these studies on practice guidelines and reimbursement policies are provided.

The knowledge, attitudes and perceptions of health care professionals at the Mahalapye District Hospital about the World Spine Care model in the Central District of BotswanaChihambakwe, Mufudzi January 2018 (has links)
Submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, Durban University of Technology, Durban, South Africa, 2018. / Background: The World Spine Care (WSC) is a non-governmental organization that provides evidence-based spinal care to underserved communities around the world. The WSC opened a clinic in the Mahalapye District Hospital (MDH) in 2011 (Haldeman et al., 2015:2304). The WSC aims for long term presence in Botswana. They will require ‘buy in’ from the local community including the health care professionals of the region. Little is known about how WSC has been received by other health care professionals in the settings where they are present. Hence, this study aimed to determine the knowledge, attitudes and perceptions of health care professionals working at the MDH about the WSC.
Method: A qualitative exploratory descriptive study was conducted using semi-structured interviews. Twenty health care professionals were interviewed at the Mahalapye District Hospital to ascertain their levels of knowledge, attitudes and perceptions. The interviews were semi- structured and conducted in English and later transcribed verbatim. The transcripts were then analyzed using the thematic analysis described by Graneheim and Lundman (2003:105). Thereafter codes, categories and themes were formed.
Results: A variety of health care professionals from different departments were interviewed. Three overarching themes emerged from the data: knowledge of WSC and the management of spinal related disorders at the MDH, the perceived role of WSC, challenges to integration and possible solutions. The HCPs had varying levels of knowledge of the WSC depending on the amount of interaction they had with WSC. Some HCPs who had greater inter-professional interaction with WSC displayed more positive attitudes towards WSC. Many of the
HCPs had a positive perception of the WSC though they were not confident in their knowledge of the WSC scope of practice which has limited referral by HCPs WSC. This is mainly due to an unclear referral pathway within the hospital and limited knowledge of WSC’s scope of practice. Increased awareness and an improved system of referral was a strong recommendation made. Many mentioned an unclear referral pathway for their patients. Those who had interacted with WSC generally had pleasant personal interactions with the WSC. Several of the HCPs had themselves been patients of the WSC. Most HCPs felt that WSC was beneficial to patients and made suggestions for WSC to expand to other centres across Botswana.
Conclusion: Overall there was a positive perception of WSC however more effort to increase knowledge of what WSC offers and how it can be integrated into the hospital is necessary. Future studies should assess the perceptions of patients as well as knowledge and attitudes of HCPs towards WSC at other sites. / M

Improvising Knowledge: A Case Study of Practices in and Around World Spine Care's Evidence-based Clinics in Shoshong and Mahalapye, BotswanaMongeon, Mylène January 2016 (has links)
Global health organizations attend to populations around the world applying an evidence-based model of care that often does not correspond with local realities on the ground. My thesis provides an in-depth anthropological study of how this occurs within practices in and around World Spine Care's (WSC) clinics in Shoshong and Mahalapye, Botswana. More specifically I explore how knowledge is negotiated and improvised on the ground, paying particular attention to the ways WSC volunteers are (un)able to work with local health workers as they desire. I show the flows and counter-flows implicated in the difficult task of reconciling skills with standards. The study is based on a total of 15 months of participation with WSC's organization through attending meetings, activities and shadowing practitioners both in Ottawa and in Botswana. Expanding the scope of their creative improvisational skills beyond the closed settings of WSC clinics is proposed as a way to move forward.
