However, because of insufficient data this variable could not be included in the multivariate analysis, even although it is possible that BMI will one day be shown to be an important, independent predictor of SSI. It would therefore seem to be likely that our analysis has included the main patient-related risk factors for SSI. Even if the key factors were missing, the proportion of patients with these characteristics would need to vary significantly between different facilities if they were to explain the variation in incidence of SSI between hospitals.

Mangram et al 5 also cited evidence for the effect of a range of factors related to surgery, and how it is performed, on the risk of SSI. These included the operating theatre environment e. Since trauma is a significant risk factor, it may be that hospitals with separate facilities for trauma and elective patients may one day be shown to be a significant factor in the analysis of risk. The extent to which some of these practices are adopted in different hospitals may explain some of the variation in rates of infection.

This variation can therefore provide a useful opportunity for evaluating local clinical practice in relation to current recommendations to ensure that the risk of SSI is minimised. Our study also highlights the impact of SSI on morbidity and the subsequent use of resources. The length of hospital stay for patients with SSI was more than twice that of those without SSI for all types of hip arthroplasty.

However, it was not possible to establish the exact relationship between the length of stay in hospital, the severity of underlying illness and the development of SSI. The data for time to diagnosis and mean length of hospital stay show that there is often a small interval between the detection of a SSI and the discharge of the patient from hospital, particularly with deep and joint infections. Patients who stay in hospital longer are more likely to have their SSI detected.

In the simplistic adjustment for length of post-operative stay using a Poisson regression, age group was no longer a significant predictor of SSI. This suggests that part of the increased risk of SSI in older patients was related to their increased length of post-operative stay and the resulting, increased opportunity for SSI to be detected.

Our study has also demonstrated the extent to which the emerging problem of infection due to methicillin-resistant strains of Staph. Nearly two-thirds of isolates of Staph. The characteristics of these patients probably increases the likelihood that they will be colonised with MRSA before surgery. There may, for example, be a history of exposure from an earlier hospitalisation, chronic wounds and other underlying illness. With continuing emphasis on clinical governance and quality control, there is increasing demand from both patients and government for methods of assessing surgical results.

Rates of morbidity and mortality may play important roles in these assessments. However, our study has indicated that, when crude comparisons between hospitals in the incidence of SSI are made, these should at least be stratified by the type of procedure. A better comparison can be made by combining data for all types of hip arthroplasty, and standardising the rates of SSI, in order to allow for the significant factors i.

These factors can be taken into account when making comparisons and should perhaps be considered when allocating special care to high-risk patients. There are some limitations to our study. Currently, there is no satisfactory and cost-effective system for the routine surveillance of post-operative patients who have been discharged from hospital. For this reason post-discharge SSIs were not included in our study. While the rates of post-discharge SSI do not represent all SSIs which develop after hip arthroplasty, it is likely that a considerable proportion will have become apparent before the patient is discharged from hospital.

However, it is also possible that the risk factors for SSI which we identified in this analysis may not apply to SSIs detected after discharge. Risk factors included in our analysis were only those for which data were available, although most major factors appear to have been incorporated. Hospitals contributing data were a self-selected group, which may introduce a small element of bias e. However, a large proportion of the NHS Trusts in England have contributed data and, for many, the reason for participation was an interest in auditing rates of SSI rather than particular concerns about its magnitude.

There was no tenderness or swelling around the joint, and the infection was regarded as resolved.

    A sinus tract communicating with knee joint was seen, around which was the yellowish fluid with tofu-like tissue Figure 1C. It did not appear to be synovial in nature so it was collected for pathogen and drug sensitivity test, which was subsequently identified as Candida albicans. The result was initially regarded as a contamination but repeated punctures confirmed the infection of C. The MIC of fluconazole for C. At that point, the WBC count was 2. The MIC of voriconazole for C. On October 20, , arthrocentesis was performed to examine the effect of the treatment method so far. The results of fungal stains, gram stains and bacterial cultures were all negative.

    The patient had no systematic discomfort and no local erythema, no local heat, no resting pain, no discharge sinus in the infected joint. After 5 months of follow-up, the film of the left knee revealed the prosthesis was well-fixed Figure 2D — F and laboratory findings were normal. Currently, the patient is on a continued 6-month oral antifungal treatment. A secondary search of references cited in the articles related to our topics was performed. The patients had an average age of A sinus tract was present in 2 patients patients 1 and 4.

    Three patients had one or more underlying systemic diseases, including COPD in 2 patients, chronic renal insufficiency in 1 patient, diabetes mellitus in 2 patients and renal cell carcinoma in 1 patient. The case in our hospital did not have systemic illness, but had a complicated history of multiple electric injury wounds to the extremity with the infected joint. Two patients with a previous history of bacterial infection prior to C. The delay between index surgery and diagnosis varied from 8 days to 4 months and 26 months; it was unavailable in 1 patient.

    Four patients developed the infection after an average of 2. Patient 1 received intravenous injection with antibiotics including flucytosine combined with amphotericin B, but without oral antibiotics.

    Associated Content

    Patients 2 and 3 underwent fluconazole combined with vancomycin hydrochloride intravenously each and oral fluconazole. Our patient received vancomycin hydrochloride intravenously 19 days for MRSA and fluconazole intravenously 18 days combined with oral fluconazole and switched to voriconazole later for C.

    Intra-articular injection was used in our patient only. PJI is a serious complication of arthroplasty associated with significant mortality. The present case had several risk factors including high frequency of door openings in the operating theater, 20 fluid resuscitation over 2, mL, 21 3 units of allogeneic red blood cells and mL fresh frozen plasma transfusion during the operation. The Pulido et al study showed patients receiving allogenic transfusions were regarded as an independent risk factor for PJI which was 2.

    In addition, the complexity of arthroplasty, such as the use of hinged implants in our case, may also contribute to high complication rate. Also in our review, these four patients had several identifiable risk factors for PJI, either systemic diseases or local comorbidities, such as poorly controlled diabetes mellitus, male gender, chronic renal disease, diagnosis of post-traumatic arthritis, prior surgical procedure in the affected joint, which was consistent with potential risk factors for development of PJI described in The International Consensus on Periprosthetic Joint Infection.

    Although reimplantation protocol resulted in a viable option for patients with infections by common organisms, it might be accompanied by a high recurrence rate, especially in patients with antibiotic resistant organisms. Our case is unique since the patient had successful eradication of infection by using open debridement, continuous lavage for MRSA infection and intra-articular washout for C.

    In vitro, PVP-I has been proved to be effective against a wide range of pathogens, including Gram-positive and Gram-negative bacteria, bacillus, protozoa and viruses. In addition, continuous lavage was used after complete debridement in our patient. Mont et al study shows that in patients with acute PJI, multiple debridement and retention of the components can result in low morbidity with high success rates. It also remains uncertain about when to remove the drainage tube, how to confirm the absence of organism and how to prevent superinfection.

    More importantly, intra-articular washout combined with oral antifungal agents was performed in our patient to control C. Salvati et al also reported that the proper antibiotic concentration in joint fluid could not be maintained by antibiotic-impregnated cement. Similar methods of intra-articular antibiotic delivery have been reported effectively in previous literature to treat acute and chronic-infected TKA.

    The agents must be adjusted according to the results of susceptibility testing because fungal biofilms are more complex than other pathogens. The reason may be that voriconazole is a more active regimen to suppress the recovery of viable colony-forming units CFUs from the model at 24 h. In addition, voriconazole-exposed catheters exhibited a significantly lower burden of organisms, revealed by sonicated catheter cultures at 48 h, versus the fluconazole for isolated C. Lastly, the authors consider whether a prolonged time of local susceptible antibiotics delivery in acute PJI might be the major issue in treatment and induce a better outcome than radical revision surgery, which has also been shown effective in some of the earlier in vitro and clinical reports, but it needs further study to prove the hypothesis.
