Intensive Cryotherapy in the Emergency Department (ICED): A Randomized Controlled Trial.

INTRODUCTION: Pain control is an essential component of musculoskeletal injury treatment in the emergency department (ED). We evaluated the most effective type of cryotherapy for analgesia of acute musculoskeletal injury and the impact on opioid utilization. METHODS: This was a prospective, randomized, single-blind controlled trial of adult ED patients who presented with acute musculoskeletal pain. Patients were randomized to either intensive targeted cryotherapy (crushed wetted ice in a plastic bag) or agitated chemical cold pack applied to the injury site for 20 minutes. All other diagnostic and therapeutic orders were at the discretion of the treating physician. Visual analog pain scores were measured at the time of cryotherapy application, at 20 minutes (time of cryotherapy removal), and at 60 minutes (40 minutes after removal). RESULTS: We enrolled 38 patients, 17 randomized to intensive targeted cryotherapy and 21 to chemical cold packs, with well-matched demographics. The intensive targeted cryotherapy group achieved significantly greater pain relief at 20 minutes (2.1 [95% confidence interval (CI), 1.3 - 2.9] vs 0.9 [95% CI, 0.3 - 1.5], P < 0.05) and at 60 minutes (2.7 [95% CI, 1.6 - 3.7] vs 1.2 [95% CI, 0.6 - 1.7], P < 0.05), number need to trial (NNT) = 3.2. Opioid administration in the ED was significantly lower in the intensive targeted cryotherapy group (1 [6%] vs 7 [33%], P < 0.05), NNT = 3.6. Those who received a discharge opiate prescription had significantly higher 60-minute pain scores (7.3 ± 2.2 vs 4.1 ± 2.7, P < 0.05). CONCLUSION: Intensive targeted cryotherapy provided more effective analgesia than chemical cold packs for acute musculoskeletal injuries in the ED and may contribute to lower opioid usage.

Increasing access to specialty surgical care: application of a new resource allocation model to bariatric surgery.

OBJECTIVES: To calculate the public health impact and economic benefit of using ancillary health care professionals for routine postoperative care. BACKGROUND: The need for specialty surgical care far exceeds its supply, particularly in weight loss surgery. Bariatric surgery is cost-effective and the only effective long-term weight loss strategy for morbidly obese patients. Without clinically appropriate task shifting, surgeons, hospitals, and untreated patients incur a high opportunity cost. METHODS: Visit schedules, time per visit, and revenues were obtained from bariatric centers of excellence. Case-specific surgeon fees were derived from published Current Procedural Terminology data. The novel Microsoft Excel model was allowed to run until a steady state was evident (status quo). This model was compared with one in which the surgeon participates in follow-up visits beyond 3 months only if there is a complication (task shifting). Changes in operative capacity and national quality-adjusted life years (QALYs) were calculated. RESULTS: In the status quo model, per capita surgical volume capacity equilibrates at 7 surgical procedures per week, with 27% of the surgeon's time dedicated to routine long-term follow-up visits. Task shifting increases operative capacity by 38%, resulting in 143,000 to 882,000 QALYs gained annually. Per surgeon, task shifting achieves an annual increase of 95 to 588 QALYs, $5 million in facility revenue, 48 cases of cure of obstructive sleep apnea, 44 cases of remission of type 2 diabetes mellitus, and 35 cases of cure of hypertension. CONCLUSIONS: Optimal resource allocation through task shifting is economically appealing and can achieve dramatic public health benefit by increasing access to specialty surgery.

Does a fibronectin and aggrecan complex play a role in painful vertebral disks?

OBJECTIVE: To determine the presence of a fibronectin-aggrecan complex (FAC) in the disk space of persons with chronic low back pain as relates to provocative diskography. DESIGN: A single-center prospective consecutive case series. SETTING: A single private practice setting. PATIENTS: Thirty-seven patients with symptomatic degenerative disk disease of the cervical, thoracic, or lumbar spine undergoing provocative diskography to identify a source of pain. METHODS: Diskographic lavage for analysis was simultaneously performed at each disk level injected during diskography. MAIN OUTCOME MEASURES: Visual analog scale (VAS) pain scores, Pfirrmann magnetic resonance imaging grade, and biochemical analysis of disk material were statistically analyzed. RESULTS: A total of 105 levels in 37 patients had a complete set of data (mean age 43.2 ± 11.9 years; 15 male/22 female). The FAC was present in 43 of 108 levels and in at least one level in 25 of 37 patients. The Pfirrmann magnetic resonance imaging grade did not differ between complex-positive and negative levels (P = .125), nor did the intraoperative VAS (IO-VAS) score for pain by level (P = .206). A significant but loose correlation was found between Pfirrmann grade and IO-VAS (R(2) = 0.4, P < .001), but no significant correlation was found between VAS or IO-VAS and complex concentration (R(2) = 0.08, P = .11 and R(2) = 0.003, P = .5). CONCLUSIONS: The FAC was identified in some painful disks by diskography. There was no significant correlation between the Pfirrmann grade or pre/intraoperative pain scores during diskography and complex concentrations within the disk measured by disk lavage.
