Outpatient parenteral antimicrobial therapy with ceftriaxone for acute tonsillopharyngitis: efficacy, patient satisfaction, cost effectiveness, and safety

Risk Factors Associated With Nephrotoxicity During Outpatient Intravenous Vancomycin Administration

Background: Many studies have described an association between intravenous vancomycin and nephrotoxicity; however, the majority have evaluated incidence and risk factors among hospitalized patients. Outpatient administration of intravenous antibiotics is a growing practice and presents its own set of unique challenges. Objective: The aim of this study was to identify risk factors for vancomycin-associated nephrotoxicity in the outpatient setting. Methods: A case-control study of patients who received intravenous vancomycin through an Outpatient Parenteral Antimicrobial Therapy (OPAT) program was conducted. Patients were identified who developed an acute kidney injury (AKI) during treatment. The primary outcome was the incidence of AKI during treatment. Results: A total of 37 out of 130 patients (28.5%) met the criteria for AKI. AKI was more likely to occur in patients with a longer duration of therapy, higher maximum trough concentration, co-administration of a fluoroquinolone or metronidazole, and those who received another potentially nephrotoxic medication. Co-administration of a fluoroquinolone (OR = 5.96, P = 0.009, [CI: 1.59, 24.38]), any nephrotoxic medication (OR = 11.17, P < 0.001, [CI 3.14, 51.23]), and a higher maximum vancomycin trough (OR = 1.29, P < 0.001, [CI 1.17, 1.44]) were all indicative of a higher odds of an AKI. Conclusion: In this cohort, vancomycin-associated nephrotoxicity was common during outpatient intravenous antibiotic therapy. Co-administration of a fluoroquinolone, any nephrotoxic medication, and a higher maximum vancomycin trough were associated with AKI development. Further study is needed to determine how this impacts long-term clinical outcomes and what measures can be taken to reduce nephrotoxicity risk.

[Cost analysis of inpatient versus outpatient intravenous antibiotic treatment for periprosthetic joint infections : A simulation]

Hintergrund

Die parenterale Antibiotikagabe im Rahmen der Therapie von periprothetischen Infektionen erfordert in der Regel eine stationäre Behandlung und geht mit hohen Kosten einher.

Fragestellung

Es wurden tatsächliche stationäre Behandlungskosten („inpatient parenteral antibiotic therapy“ [IPAT]) mit simulierten Kosten einer ambulanten Behandlung („outpatient parenteral antibiotic therapy“ [OPAT]) von Patienten mit periprothetischen Gelenkinfektionen verglichen. Die Auswertung erfolgte aus Perspektive der Kostenträger (gesetzliche Krankenversicherung [GKV]) und Leistungserbringer (Krankenhäuser).

Material und Methoden

Die Analyse und Simulation erfolgten auf Grundlage einer ICD-10 (Internationale statistische Klassifikation der Krankheiten und verwandter Gesundheitsprobleme, 10. Revision) für das Behandlungsjahr 2015 mit der Diagnose T84.

Ergebnisse

Die simulierte Reduktion von 159 Bettentagen bei den in die Studie eingeschlossenen 12 Patienten erbrachte aus Sicht der Kostenträger eine Reduktion der Gesamtkosten um >18.000 €. Aus Perspektive der Leistungserbringer verbesserte sich der Reinerlös um >22.000 €. Die Gesamtkosten der OPAT für den Kostenträger beliefen sich auf >57.000 €. Für den Leistungserbringer zeigte sich in der Differenz von Poliklinikerlös und -kosten der OPAT ein Verlust von >1500 €.

Diskussion

Die OPAT ist für Leistungserbringer insgesamt finanziell vorteilhaft. Weitere Vorteile durch Opportunitätskosten erscheinen interessant. Für den Kostenträger ist die OPAT insbesondere durch die ambulanten Medikamentenkosten mit einem finanziellen Mehraufwand verbunden. Der niedergelassene Sektor sollte durch die anzunehmende Mehrbelastung ebenso wie der anzunehmende Patientenkomfort bedacht werden.

Systematic Review: Study of the Prescribing Pattern of Antibiotics in Outpatients and Emergency Departments in the Gulf Region

Purpose: To study the prescribing pattern of antibiotics in outpatients and emergency departments in the Gulf region. To compare the appropriateness of prescriptions and antibiotics commonly prescribed for respiratory tract infection.

Method: The search was limited to the years 2008–2020, and articles had to be in English. Articles were searched from various resources and evaluated using PRISMA. Forty-one articles were selected and screened, and in the end, 17 articles were included in the study. All articles were selected from the gulf region of six countries: UAE, Saudi Arabia, Qatar, Oman, Yemen, and Bahrain. Only primary literature were included. Inpatient and literature from other countries outside the gulf region were excluded.

Result: Penicillins, cephalosporins, and macrolides are highly useful antibiotics for respiratory tract infections. Ceftriaxone IV is recommended in acute respiratory tract infection if therapy with penicillin fails. Most of the antibiotic prescriptions in Gulf countries are inappropriate. Inappropriate antibiotic prescribing in the gulf region varies from place to place and reaches a maximum of 80%. Antibiotics may be prescribed with the wrong dosage or frequency and inappropriate guidelines. Penicillins are prescribed at about 50–60%; the most common penicillins prescribed are amoxicillin and co-amoxiclave. Cephalosporins are prescribed at about 30%, and the most common are third-generation. Macrolides are prescribed at about 17–20%, and the most common macrolides are azithromycin and clarithromycin. Fluoroquinolones are prescribed at about 10–12%, of which levofloxacin and ciprofloxacin are more commonly prescribed with metronidazole at 10%.

Conclusion: It is suggested that the antibiotic-prescribing pattern in outpatient and emergency departments in the Gulf region are highly inappropriate and need improvement through education, following guidelines, annual vaccination, and stewardship programs; the most prescribed antibiotic is amoxicillin/co-amoxiclave, and the most often encountered infection in outpatients is acute respiratory tract infection.

Cost-analysis of inpatient and outpatient parenteral antimicrobial therapy in orthopaedics: A systematic literature review

BACKGROUND

Increasing numbers of total joint arthroplasties and consecutive revision surgery are associated with the risk of periprosthetic joint infections (PPJI). Treatment of PPJI is complex and associated with immense socio-economic burden. One treatment aspect is parenteral antiinfective therapy, which usually requires an inpatient setting [Inpatient parenteral antibiotic therapy (IPAT)]. An alternative is outpatient parenteral treatment [Outpatient parenteral antibiotic therapy (OPAT)]. To conduct a health economic cost-benefit analysis of OPAT, a detailed cost analysis of IPAT and OPAT is required. So far, there is a lack of knowledge on the health economic effects of IPAT and OPAT for PPJI.

AIM

To review an economic comparison of IPAT and OPAT.

METHODS

A systematic literature review was performed through Medline following the PRISMA guidelines.

RESULTS

Of 619 identified studies, 174 included information of interest and 21 studies were included for quantitative analysis of OPAT and IPAT costs. Except for one study, all showed relevant cost savings for OPAT compared to IPAT. Costs for IPAT were between 1.10 to 17.34 times higher than those for OPAT.

CONCLUSION

There are only few reports on OPAT for PPJI. Detailed analyses to support economic or clinical guidelines are therefore limited. There is good clinical evidence supporting economic benefits of OPAT, but more high quality studies are needed for PPJI.

Effect of Ceftriaxone versus Amoxicillin + Clavulanic Acid for Treatment of Acute Bacterial Rhino Sinusitis: Short Course Therapy

BACKGROUND:

Acute bacterial rhinosinusitis is one of upper respiratory tract infection that disturbs patient life and requires special consideration.

AIM:

To evaluate the efficiency of Ceftriaxone versus a high dose of Amoxicillin-clavulanic acid for the treatment of acute bacterial rhinosinusitis.

PATIENTS AND METHOD:

Observational retrospective study include120 patients of both sex classified into two groups equally conducted. G1 treated with Ceftriaxone 1 g intramuscular injection once daily while, G2 treated with oral Amoxicillin-clavulanic acid (875 mg/125 mg) twice daily for 3-4 days then, the outcome of treatment evaluated as a cure or failed at the fifth or fourth day of treatment.

RESULTS:

Significant cure response observed in Ceftriaxone treated patient’s P ≤ 0.05 and significant failure response observed in Amoxicillin-clavulanic acid-treated patients when groups compared with each other. About gender and age groups, no significant differences in number between group 1 and 2 P ≥ 0.05.

CONCLUSION:

Ceftriaxone found more effective in the treatment of acute bacterial sinusitis than Amoxicillin+ clavulanic acid. Amoxicillin+clavulanic acid associated with more male failure cases recorded than female.
