ABSTRACT
INTRODUCTION: Controversy exists regarding whether spinal implants need to be removed to treat postoperative deep wound infections (DWIs). This retrospective study aimed to determine whether the removal or retention of implants impacts the successful treatment of a DWI after spine surgery. METHODS: Postoperative spine surgery patients presenting with signs of infection who underwent irrigation and debridement (I&D) at Twin Cities Spine Surgeons at Abbott Northwestern Hospital, Minnesota, USA, were studied. First, the persistence of infection when implants were retained or removed was assessed. Second, we analyzed the persistence of infection with respect to the number of I&D, the use of vacuum-assisted closure (VAC) treatment, pseudoarthrosis status, and functional outcomes. RESULTS: One hundred thirty-five patients were included. Treatment of infection with retention of implants occurred in 64% (87/135); of these, 7% (6/87) had a persistent infection. Of patients with implant removal (36%, 48/135), 6% (3/48) had a persistent infection. Thus, we observed no difference between treatment with implants present compared to implants removed (p = 1.0). Fifty of the 135 patients (37%) received I&D and primary wound closure, and 85 (63%) patients received I&D and VAC treatment. There was no statistical difference between primary wound closure and VAC treatment (p = 0.15) with respect to persistence. Repeat I&D with VAC (three or more times) had a significantly lower rate of recurrence than those with two I&Ds. Pseudoarthrosis and persistent infection were unrelated. At minimum one-year follow-up, achieving a minimum clinically important difference in functional outcome was independent of persistent infection status. CONCLUSION: Persistent infection was unrelated to the retention of implants. When VAC treatment was deemed necessary, more than two I&Ds resulted in a significantly better cure for infection. Those with a persistent infection were no more likely to exhibit pseudoarthrosis than those with no persistent infection. All patients showed improvement in functional outcomes at minimum one-year follow-up.
ABSTRACT
This article describes the organization and outcomes of a Rural Health Outreach Initiative (RHOI) designed to increase collaboration between the medical education and health care delivery sectors to improve the quality of health care delivery and health outcomes in rural communities. Two inter-related partnership strategies were utilized in rural communities to address the health and social service needs of rural populations. The partnerships were created through the efforts of a rural health professions education program located in a community-based medical school. The two partnership models were implemented at the same time and target the same rural populations. Both strategies relied upon interdisciplinary collaborations to achieve their goals and outcomes. One strategy involved the creation of partnerships among rural medical students and the projects they initiate, using the model of community oriented primary care (COPC). The second strategy involved the establishment of partnerships by a variety of rural, community-based entities that resulted from a three-year Health Resources and Services Administration Rural Health Outreach grant that supported a "mini-grant" program. This article summarizes the process and results of these innovative collaborations that occurred at two levels: (1) between health and service institutions representing multiple disciplines and (2) between academic institutions and local communities. Specific attention is given to projects that resulted from the work of the partnerships that address the needs of older adults residing in the rural communities. The two strategies are compared and implications for the success of similar efforts are discussed.
