The Federal Food and Drug Administration (FDA) and the Centers for Medicare and Medicaid (CMS) play key roles in making Class III, medical devices available to the public, and they are required by law to meet statutory deadlines for applications under review. Historically, both agencies have failed to meet their respective statutory requirements. Since these failures affect patient access and may adversely impact public health, Congress has enacted several “modernization” laws. However, the effectiveness of these modernization laws has not been adequately studied or established for Class III medical devices. ^ The aim of this research study was, therefore, to analyze how these modernization laws may have affected public access to medical devices. Two questions were addressed: (1) How have the FDA modernization laws affected the time to approval for medical device premarket approval applications (PMAs)? (2) How has the CMS modernization law affected the time to approval for national coverage decisions (NCDs)? The data for this research study were collected from publicly available databases for the period January 1, 1995, through December 31, 2008. These dates were selected to ensure that a sufficient period of time was captured to measure pre- and post-modernization effects on time to approval. All records containing original PMAs were obtained from the FDA database, and all records containing NCDs were obtained from the CMS database. Source documents, including FDA premarket approval letters and CMS national coverage decision memoranda, were reviewed to obtain additional data not found in the search results. Analyses were conducted to determine the effects of the pre- and post-modernization laws on time to approval. Secondary analyses of FDA subcategories were conducted to uncover any causal factors that might explain differences in time to approval and to compare with the primary trends. The primary analysis showed that the FDA modernization laws of 1997 and 2002 initially reduced PMA time to approval; after the 2002 modernization law, the time to approval began increasing and continued to increase through December 2008. The non-combined, subcategory approval trends were similar to the primary analysis trends. The combined, subcategory analysis showed no clear trends with the exception of non-implantable devices, for which time to approval trended down after 1997. The CMS modernization law of 2003 reduced NCD time to approval, a trend that continued through December 2008. This study also showed that approximately 86% of PMA devices do not receive NCDs. ^ As a result of this research study, recommendations are offered to help resolve statutory non-compliance and access issues, as follows: (1) Authorities should examine underlying causal factors for the observed trends; (2) Process improvements should be made to better coordinate FDA and CMS activities to include sharing data, reducing duplication, and establishing clear criteria for “safe and effective” and “reasonable and necessary”; (3) A common identifier should be established to allow tracking and trending of applications between FDA and CMS databases; (4) Statutory requirements may need to be revised; and (5) An investigation should be undertaken to determine why NCDs are not issued for the majority of PMAs. Any process improvements should be made without creating additional safety risks and adversely impacting public health. Finally, additional studies are needed to fully characterize and better understand the trends identified in this research study.^

Since early 2000, the Western Cape of South Africa has been documented as an area for monitoring the spread of HIV. The majority of HIV cases occur within individuals between the ages of 15-49 years, and the epidemic is believed to be complicated by the increased use of crystal methamphetamine (CM), or “tik.” Eighty percent of current CM users in Cape Town are under the age of 21 years, and almost 18% of current HIV cases are in individuals under the age of 24 years. Gang membership in youth may also be complicating the HIV problem as gangs feed the social acceptability of “tik” and encourage sexual violence. With almost half the population of Cape Town in their mid-twenties, the threat of a new HIV epidemic complicated by CM use has become a concern in the young adults of the city. Research into the relationships between gang membership and drugs/violence has been extensively studied in the Cape Flats. Yet, few have examined the role of gangs in the perpetuation of HIV. Therefore, the purpose of this investigation was exploratory in nature. Key informant interviews from Cape Town youth were used as case illustrations to generate potential hypotheses on the interrelationships between “gangsterism,” “tik” use, and HIV. Such awareness is important if effective efforts to reduce HIV incidence in Cape Town (and Sub-Saharan Africa) are to transpire. If the problem of CM is not addressed quickly, the Cape Flats may find itself with a higher rate of an already uncontrollable HIV epidemic. ^
