Response/Recommendation: The current evidence does not demonstrate notable differences in the clinical outcomes between different types of intermittent pneumatic compression devices (IPCD). However, devices with sensors and uniform compression may improve patient compliance.
Strength of Recommendation: Moderate.
Rationale: There are numerous types of IPCD currently available1-3. These devices can be categorized into anatomical locations of application, such as thigh-calf compression, calf compression only, and foot compression. In addition, these devices can be subdivided into providing sequential or uniform pressure, gradual or rapid inflation, and portable (outpatient) or stationary (in-hospital) devices2,3. The assessment of efficacy for IPCD is complicated by the inclusion of various types and doses of anticoagulant and antithrombotic medications in the published studies. The outcomes evaluated included: venous thromboembolism (VTE), (deep venous thrombosis [DVT], and pulmonary embolism [PE]), adverse events, such as postoperative bleeding and swelling, ease of application and use, and patient compliance with the device2-8.
Determining differences in the efficacy and other outcomes between the numerous IPCD on the market is not possible, because these devices have been evaluated in small number of randomized controlled trials (RCT) that were underpowered3,9. The influence of the amount of pressure, inflation rate, timing of initiation, and duration of prophylaxis for maximum benefit are still unclear10,11. There is little evidence for the comparison of efficacy of IPCD between different orthopaedic procedures, although the benefits have been generally accepted in total knee arthroplasty (TKA), total hip arthroplasty (THA), and hip fracture surgery2,3,9,11.
In a systematic review, Zhang et al.3, noted one RCT comparing patients with thigh-calf-compression (n=58) and foot compression (n=63) in first 3 weeks after THA3. There no cases of symptomatic DVT or PE in either group3,12. Postoperative swelling of the thigh, as measured by thigh circumference, was significantly milder in thigh-calf compression group (1.22%) than in foot compression group (3.19%)3,12. This study was underpowered, with a high risk of bias. One recent meta-analysis noted that venous foot pumps decreased the rate of VTE after THA and TKA compared to chemical prophylaxis13. One comprehensive review of IPCD in orthopaedic surgery made recommendations based on the levels of evidence and adherence to established guidelines14. Compression stockings alone were the lowest-rated, and venous phasic flow-regulated below-knee sequential IPCD were the highest rated in each grading category14. However, this review included studies with heterogeneous low level of evidence. The superiority of IPCD depending on anatomical location is uncertain, and high-quality studies with large numbers of patients would be required to determine this.
A sequential compression device (SCD) would seem more hemodynamically effective due to the increase in blood flow and prevention of venous stasis, one factor in the initiation of DVT4,15. One retrospective comparative study reported that a SCD had lower rate of VTE, better compliance, and shorter length of hospital day than a uniform IPCD in 1,577 cases after total joint arthroplasty (TJA)16. Other clinical studies have not reported significant differences in the incidence of VTE, comparing sequential to uniform IPCD15,17. There are no high-quality, adequately powered comparative studies on the type of compression.
Pavon et al.2, performed comprehensive systematic review of 14 RCT with 2,633 cases and 3 observational studies with 1,724 cases to evaluate effectiveness of IPCD in patients after TJA. Only 3 RCT directly compared different types of IPCD for VTE events9,18,19. One adequately powered RCT study (moderate risk of bias) of 423 patients having TKA compared a rapid-inflation calf SCD (VenaFlow [Aircast, Summit, NJ]) and a slow-inflation calf SCD (Kendall SCD [Kendall, Mansfield, MA]). The rate of DVT was significantly lower in rapid inflation group than the slow compression group9. Another likely underpowered RCT (high risk of bias) compared Kendall SCD to a rapid-inflation IPCD (PlexiPulse [NuTech, San Antonio, TX]) in 107 patients having pelvic fracture surgery and reported no difference in the rate of VTE events between the two groups18. A third likely underpowered RCT (moderate risk of bias) also compared Kendall SCD with PlexiPulse in 136 patients having spinal surgery and reported no significant differences19. There were no major bleeding events in these three RCT9,18,19. This systematic review concluded that current evidence-based to guide selection of a specific device or type of device is limited2.
Despite the benefits of IPCD, research has shown considerable variability in adherence to IPCD use ranging from 40% – 89%20 and a systematic review identified several factors affecting the adherence such as patient discomfort and mobilisation21. In evaluating the adherence to different IPCD, a systematic review included three RCT18,19,22 including 308 patients, and 3 observational studies17,23,24 including 1,724 patients2. Two studies compared PlexiPulse foot device and Kendall SCD calf-thigh device regarding ease of use. One moderate-sized RCT19 reported no difference in comfort ratings. One larger observational study noted that PlexiPulse device was more comfortable24. Another small RCT22, comparing the ease of use between Kendall intermittent slow calf device and Flowtron (Huntleigh, Manalapan, NJ) uniform slow compression calf device, reported that Flowtron device was more comfortable for patients and more convenient for hospital staff22. An observational study compared five different devices, with multiple different sleeve types, and noted no significant difference in ease of use17. Comparing in-hospital patient compliance, there were no consistent associations between specific manufacture’s devices or location of sleeve and patient compliance2. The addition of patient sensing technology, such as the one seen in Kendell SCD, is believed to improve patient compliance and ability of health staff to track patient therapy.
Portable devices for IPCD after surgery and for use at home have been developed recently and potentially allow better compliance, patient satisfaction, and continuation of mechanical VTE prophylaxis after discharge25-27. Although portable IPCD has shown effective mechanical prophylaxis for VTE after THA and TKA16, the evidence is limited due to confounding variables. One observational study reported that a portable (mobile) IPCD had significantly better compliance, lower rate of DVT, reduction in symptomatic PE, and shorter length of hospital stay than a stationary IPCD16. However, all patients were also given pharmacologic prophylaxis with low-molecular-weight heparin16.
Although there are important differences between various IPCDs in anatomical sleeve location, inflation pattern, and device portability, the available evidence is limited to recommend a certain IPCD type for patients having a specific surgical procedure.
