European confederation of medical mycology quality of clinical candidaemia management score: A review of the points based best practice recommendations

The interplay of infectious diseases consultation and antimicrobial stewardship in candidemia outcomes: A retrospective cohort study from 2016 to 2019

OBJECTIVE

To evaluate the need for mandatory infectious diseases consultation (IDC) for candidemia in the setting of antimicrobial stewardship guidance.

DESIGN

Retrospective cohort study from January 2016 to December 2019.

SETTING

Academic quaternary-care referral center.

PATIENTS

All episodes of candidemia in adults (n = 92), excluding concurrent bacterial infection or death or hospice care within 48 hours.

METHODS

Primary outcome was all-cause 30-day mortality. Secondary outcomes included guideline-adherence and treatment choice. Guideline-adherence was assessed with the EQUAL Candida score.

RESULTS

Of 186 episodes of candidemia, 92 episodes in 88 patients were included. Central venous catheters (CVCs) were present in 66 episodes (71.7%) and were the most common infection source (N = 38, 41.3%). The most frequently isolated species was Candida glabrata (40 of 94, 42.6%). IDC was performed in 84 (91.3%) of 92 candidemia episodes. Mortality rates were 20.8% (16 of 77) in the IDC group versus 25% (2 of 8) in the no-IDC group (P = .67). Other comparisons were numerically different but not significant: repeat blood culture (98.8% vs 87.5%; P = .17), echocardiography (70.2% vs 50%; P = .26), CVC removal (91.7% vs 83.3%; P = .45), and initial echinocandin treatment (67.9% vs 50%; P = .44). IDC resulted in more ophthalmology examinations (67.9% vs 12.5%; P = .0035). All patients received antifungal therapy. Antimicrobial stewardship recommendations were performed in 19 episodes (20.7%). The median EQUAL Candida score with CVC was higher with IDC (16 vs 11; P = .001) but not in episodes without CVC (12 vs 11.5; P = .81).

CONCLUSIONS

In the setting of an active antimicrobial stewardship program and high consultation rates, mandatory IDC may not be warranted for candidemia.

EQUAL CPA Score 2022: a tool to measure guideline adherence for chronic pulmonary aspergillosis

BACKGROUND

Chronic pulmonary aspergillosis (CPA) can complicate underlying pulmonary diseases, and clinical management of CPA is challenging. Guidelines support clinicians but due to the complexity of the disease they can be difficult to adhere to.

OBJECTIVES

To map current guideline recommendations for the clinical management of CPA into a scoring tool to facilitate and quantify guideline adherence in clinical practice.

METHODS

Recommendations for diagnosis, treatment and follow-up of CPA presented in the current ESCMID/ERS/ECMM and CPAnet guidance documents were assembled and weighed on the basis of their strength of recommendation and level of evidence.

RESULTS

Twenty-seven recommendations were identified, resulting in a total maximum EQUAL CPA Score of 51. For diagnostics (ScoreMax = 27), a strong emphasis on expert consultation, culture, direct microscopy, histopathology, serology and imaging was reflected in respective points, whereas molecular techniques and susceptibility testing count into the diagnostics score to a lesser extent.Ten treatment recommendations (ScoreMax = 14), including antifungal therapy, therapeutic drug monitoring and treatment duration, were identified. Surgery, where indicated, adds three points. For refractory disease or intolerance of first-line antifungal treatment, optimal second-line treatment added another two points.During follow-up (ScoreMax = 10), response assessment via imaging gave three points, while culture and serology added two points each to the ScoreMax.

CONCLUSION

The EQUAL CPA Score intents to be used as a comprehensive tool for measuring guideline adherence. If adherence to current guidelines is associated with clinical outcome, this will be assessed in future studies.

OUP accepted manuscript

Background

Invasive infections due to Trichosporon spp. are life-threatening opportunistic fungal infections that require complex clinical management. Guidelines assist clinicians but can be challenging to comply with.

Objectives

To develop a scoring tool to facilitate and quantify adherence to current guideline recommendations for invasive trichosporonosis.

Methods

We reviewed the current guideline for managing rare yeast infections (ECMM, ISHAM and ASM). The most important recommendations for diagnosis, treatment and follow-up were assembled and weighted according to their strength of recommendation and level of evidence. Additional items considered highly relevant for clinical management were also included.

Results

The resulting EQUAL Trichosporon Score 2022 comprises 18 items, with a maximum score of 39 points. For diagnostics, seven or eight items, depending on whether organ involvement is present or not, apply, resulting in a maximum of 18 or 21 points. Recommendations on diagnostics include imaging, infectious diseases expert consultation, culture, microscopy, molecular techniques, histopathology, and susceptibility testing. For treatment, six recommendations with a maximum of ten points were identified, with two additional points for organ involvement and one point for second-line treatment in uncontrolled disease. Treatment recommendations include immediate initiation, source control, pharmacological treatment, therapeutic drug monitoring, treatment duration and surgical intervention. Follow-up comprises two items with five points maximum, covering follow-up blood cultures and imaging.

Conclusions

The EQUAL Trichosporon Score weighs and aggregates factors recommended for optimal management of Trichosporon infections. It provides a tool for antifungal stewardship as well as for measuring guideline adherence, but remains to be correlated with patient outcomes.

EQUAL Score Scedosporiosis/Lomentosporiosis 2021: a European Confederation of Medical Mycology (ECMM) tool to quantify guideline adherence

Background

Invasive scedosporiosis and lomentosporiosis are life-threatening fungal infections in immunocompromised patients with complex diagnostic and treatment patterns.

Objectives

To develop a scoring tool to facilitate and quantify adherence to current guideline recommendations for diagnosis, treatment and follow-up of invasive scedosporiosis and lomentosporiosis.

Methods

Experts from European Confederation of Medical Mycology (ECMM) excellence centres reviewed current guidelines for scedosporiosis and lomentosporiosis. Recommendations for diagnosis, treatment and follow-up were summarized, assembled and weighted according to their strength of recommendation and level of evidence (strongly recommended = 3 points; moderately recommended = 2 points; marginally recommended = 1 point; recommended against = 0 points). Additional items considered of high importance for clinical management were also weighted.

Results

A total of 170 recommendations were identified. A 21-item tool was developed and embedded into the EQUAL score card. Nine items for diagnosis with 18 achievable points were assembled. For treatment, three general recommendation items with a maximal score of 9 were identified, while for specific antifungal treatment the two fungal pathogens were separated. Three and four items were established for scedosporiosis and lomentosporiosis, respectively, with a maximum achievable score of 3 due to the separation of different treatment options with the maximum point value of 3 for voriconazole-based treatment. Follow-up comprised two items (4 points maximum). Key recommendations for clinical outcome were weighted accordingly.

Conclusions

We propose the EQUAL Score Scedosporiosis/Lomentosporiosis to quantify adherence to current guideline recommendations for management of these rare infections. The score remains to be validated in real-life patient cohorts and correlated with patient outcome.
