RESUMO

OBJECTIVES: The ISPR was initially created to monitor the product performance of Medtronic implanted intrathecal drug infusion and spinal cord systems available in the United States. MATERIALS AND METHODS: Data were collected from 50 representative sites implanting and following patients with intrathecal drug delivery systems across the United States between August 7, 2003 and January 31, 2014. Device performance over time was estimated using life table survival methods. RESULTS: Of the 6093 patients enrolled in the ISPR, 3405 (55.9%) were female and 2675 (43.9%) were male, and 13 (0.2%) did not provide gender data. The average age at enrollment was 52.9 years (SD =17.6 years) and average follow-up time was 29.6 months. Currently, the estimates of device survival from pump-related events exceed 90% for all pump models across the applicable follow-up time points. The majority of product performance events were catheter-related. At 5 years of follow-up, all applicable catheter models, with the exception of revised not as designed or grafted not as designed catheters, had greater than 81% survival from catheter-related events. CONCLUSIONS: The ISPR is designed to serve as an ongoing source of system and device-related information with a focus on "real-world" safety and product performance. ISPR data continue to be used to guide future product development efforts aimed at improving product reliability and quality.

RESUMO

OBJECTIVES: The Implantable Systems Performance Registry (ISPR) was created to monitor the product performance of Medtronic Spinal Cord Stimulation (SCS) and implanted intrathecal drug infusion systems available in the United States. MATERIALS AND METHODS: Data were collected on 2605 patients from 44 centers from various geographic regions across the United States implanting and following patients with SCS systems between June 25, 2004 and January 31, 2014. Actuarial life table methods are used to estimate device performance over time. Of the 2605 patients, 1490 (57.2%) were female, 1098 (42.1%) were male and 17 (0.7%) did not provide gender data. The average age at enrollment was 56.3 years (range: 4-97, SD = 14.3) and average follow-up time was 20.1 months (SD = 22.5). RESULTS: Currently the estimates of device survival from neurostimulator-related events exceed 97% for all neurostimulator models across the applicable follow-up time points and all applicable extension models had greater than 95% survival from extension events. The majority of product performance events were lead-related. At 5 years of follow-up, all applicable lead families, with the exception of the Pisces-Quad LZ family, had greater than 75% survival from lead events. CONCLUSIONS: The ISPR is designed to serve as an ongoing source of system and device-related information with a focus on "real-world" safety and product performance. ISPR data continue to be used to guide future product development efforts aimed at improving product reliability and quality.

RESUMO

OBJECTIVES: The current study was conducted to compare the effectiveness of delivering diabetes education in either a group or individual setting using a consistent, evidence-based curriculum. RESEARCH DESIGN AND METHODS: A total of 170 subjects with type 2 diabetes were randomly assigned to either group (n = 87) or individual (n = 83) educational settings. Subjects received education in four sequential sessions delivered at consistent time intervals over a 6-month period. Outcomes included changes in knowledge, self-management behaviors, weight, BMI, HbA(1c), health-related quality of life, patient attitudes, and medication regimen. Changes were assessed at baseline and after the 2-week, 3-month, and 6-month education sessions. RESULTS: Both educational settings had similar improvements in knowledge, BMI, health-related quality of life, attitudes, and all other measured indicators. HbA(1c) decreased from 8.5 +/- 1.8% at baseline to 6.5 +/- 0.8% at 6 months (P < 0.01) in the study population as a whole. Subjects assigned to the individual setting had a 1.7 +/- 1.9% reduction in HbA(1c) (P < 0.01), whereas subjects assigned to the group setting had a 2.5 +/- 1.8% reduction in HbA(1c) (P < 0.01). The difference in HbA(1c) improvement was marginally greater in subjects assigned to group education versus individualized education (P = 0.05). CONCLUSIONS: This study demonstrates that diabetes education delivered in a group setting, when compared with an individual setting, was equally effective at providing equivalent or slightly greater improvements in glycemic control. Group diabetes education was similarly effective in delivering key educational components and may allow for more efficient and cost-effective methods in the delivery of diabetes education programs.
