Complications associated with outpatient parenteral antibiotic therapy in children

Hospital at Home Program for the Treatment of Pediatric Osteoarticular Infections

OBJECTIVES

Hospital at home (HAH) replaces acute inpatient hospital care for selected patients by providing care in their homes. We sought to describe the characteristics, management, and complications of patients with osteoarticular infections (OAIs) treated in an HAH program and its economic impact.

METHODS

We conducted a retrospective observational study evaluating an HAH program in a pediatric hospital in Spain, describing the characteristics of patients with confirmed OAIs requiring intravenous antibiotic therapy admitted to this program between January 2019 and December 2022. The program operates as a virtual ward with possible daily visits by physicians and nurses and 24/7 telephone contact.

RESULTS

A total of 88 patients (median age, 4.1 years; interquartile range [IQR], 1.7-10.6) with OIAs were admitted to the HAH program. Osteomyelitis (57%) and septic arthritis (29%) were the most frequent infections. Cefuroxime (42%) and cefazolin (39%) were the most frequently prescribed antibiotics. Caregiver self-administration was performed in 99%, allowing multiple daily doses of antimicrobial therapy, 80% by peripheral line. Thirteen patients (15%) had drug-related adverse events, only 3 requiring drug modification. Two patients (2%) were readmitted during HAH, and 1 was readmitted within 30 days of HAH discharge. The median HAH stay was 7 days (IQR, 4-8.75). For osteomyelitis, hospital days lowered from 8.5 days (IQR, 4.5-12) to 4 days (IQR, 3-7) after HAH implementation (P = .005) with 68% per-patient estimated cost savings.

CONCLUSIONS

HAH treatment of OAIs is effective and cost-efficient. Patient support by medical and nursing staff, adequate family training, and regular communication are essential to ensure safe home admission.

Safety and Clinical Outcomes of Hospital in the Home

OBJECTIVES

The aim of the study was to evaluate clinical outcomes and adverse events (AEs) experienced by patients treated within the Hospital in the Home (HITH) service of a major metropolitan hospital in South Australia.

METHODS

A retrospective case note audit of 100 HITH episodes among adults who received continuous intravenous antimicrobial therapy via an elastomeric or electronic infusion device was undertaken. Age- and sex-adjusted binomial logistic regression analyses were undertaken to identify factors associated with major and minor AEs.

RESULTS

Of the 100 patients included, 71 were male and the mean (SD) patient age was 62.8 (17.19) years. Elastomeric infusion devices were used for 98 patients. The mean (SD) HITH treatment duration was 20.1 (11.9) days. Overall, 130 AEs were documented for 72 patients (72%), of whom 12 patients experienced a major AE and 68 patients experienced a minor AE. There were 45 occasions among 23 patients where an infusion administered through an elastomeric device did not run to completion. Fifteen patients were readmitted to hospital. Minor AEs were more likely among people with more vascular line days (adjusted odds ratio [aOR] = 1.05; 95% confidence interval (CI) = 1.01-1.10 per day increase) and females (aOR = 4.43; 95% CI = 1.14-17.17). An increased number of vascular line days was associated with an increased likelihood of an incomplete infusion (aOR = 1.05; 95% CI = 1.01-1.09). Hospital readmission was more likely with increasing age (aOR = 1.06; 95% CI = 1.01-1.11 per year increase).

CONCLUSIONS

Adverse events need to be monitored carefully when HITH treatment is provided for extended periods.

[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.

Impact of expanding a paediatric OPAT programme with an antimicrobial stewardship intervention

BACKGROUND

As treatment out of hospital with outpatient parenteral antimicrobial therapy (OPAT) increases, so too does the risk for patients of being less visible, with potential for suboptimal care.

OBJECTIVES

We aimed to compare pre-expansion and post-expansion (1) successful completion, complications and (2) the impact of an OPAT-specific antimicrobial stewardship (AMS) intervention to mitigate inappropriate antibiotic prescribing.

DESIGN

A prospective longitudinal study during two consecutive 12-month periods: period A (1 August 2012 to 31 July 2013) and period B (1 August 2013 to 31 July 2014).

SETTING

The Hospital-in-the-Home (HITH) programme at The Royal Children's Hospital Melbourne.

PARTICIPANTS

All patients who received OPAT during the study period.

INTERVENTIONS

Between the two periods, the programme expanded from 16 to 32 patients/day. To coincide with this, a combined AMS intervention was introduced: (1) OPAT-specific guidelines and (2) active review of OPAT prescriptions and input by Paediatric Infectious Diseases.

MAIN OUTCOMES

Successful completion of OPAT, OPAT-related complications, readmission, length of stay and antibiotic appropriateness.

RESULTS

Over 2 years, 646 patients (47% female, median age 7 years) were treated via OPAT for 754 episodes. Patient episodes increased from 254 in period A to 500 in period B, with proportional increases in infants under 1 month and immunocompromised patients. OPAT was successfully completed in 245/251 (98%) versus 473/482 (98%) (OR 1.8, 95% CI 0.7 to 4.5, p=0.3). OPAT-related complications remained low: intravenous catheter-associated complications 16/138 (12%) versus 41/414 (10%), and antibiotic-associated complications 0/254 (0%) versus 2/500 (0.4%). Despite the increase in activity, with the AMS intervention, overall appropriate antibiotic prescribing remained high: 71% versus 76%. Inappropriately long durations reduced from 30/312 (10%) to 37/617 (6%) (OR 0.6, 95% CI 0.4 to 0.99, p=0.04), and median number of days on broad-spectrum antibiotics from 11 (IQR 8-24.5) to 8 (IQR 5-11).

CONCLUSION

During a period of substantial expansion, we maintained clinical outcomes. A modest AMS intervention reduced some but not all aspects of inappropriate antibiotic prescribing.

Safety of Nurse- and Self-Administered Paediatric Outpatient Parenteral Antimicrobial Therapy

This study aimed to compare and contrast the safety and efficacy of nurse- and self-administered paediatric outpatient parenteral antimicrobial therapy (OPAT) models of care and to identify clinical factors associated with documented adverse events (AEs). A total of 100 OPAT episodes among children aged between 1 month and 18 years who were discharged from hospital and who received continuous 24 h intravenous antimicrobial therapy at home via an elastomeric infusion device were included. All documented AEs from the case notes were reviewed by a paediatrician and classified as either major or minor. Multivariable logistic regression was used to determine associations between clinical factors and any AE. A total of 86 patients received 100 treatment OPAT episodes (49 self-administered, 51 nurse administered). The most commonly prescribed antimicrobial via continuous infusion was ceftazidime (25 episodes). Overall, an AE was recorded for 27 (27%) OPAT episodes. Major AEs was recorded for 15 episodes and minor AEs were reported in 14 episodes. The odds of an AE was increased in episodes with self-administration (adjusted odds ratio (aOR) 6.25, 95% confidence interval (CI) 1.44–27.15) and where the duration of vascular access was >14 days (aOR 1.08, 95%CI 1.01–1.15). Our findings suggest minor AEs may be more frequently reported when intravenous antimicrobials are self-administered via 24 h continuous infusions.

Safety of Peripherally Inserted Central Catheter Use in Children From Rural Versus Urban Settings Receiving Long-term Parenteral Antimicrobial Therapy

OBJECTIVES

To determine the safety of peripherally inserted central catheter (PICC) use for delivery of outpatient parenteral antimicrobial therapy (PAT) in children discharged to rural or urban locales. We hypothesized that children from rural settings would experience higher complication rates.

PATIENTS AND METHODS

We conducted a retrospective cohort study of children admitted to an academic medical center in the Southwestern United States over 9 years who were discharged with a PICC to complete a course of PAT with follow-up at our institution. To classify rural versus urban residence, we used rural-urban continuum codes from the US Department of Agriculture, the driving time in hours to the nearest trauma center, and the discharging center using Google Maps.

RESULTS

In total, 221 children met inclusion criteria (mean age 9.8 years). Osteoarticular infections and cystic fibrosis exacerbations were the most common indications for PICC use (68.8%). The mean driving time to the discharging hospital was significantly longer for those children residing in the most rural regions of the state (3.6 vs 0.8 hours; P < .001) as well as to the nearest level 1, 2, or 3 trauma center (2.2 vs 0.4 hours; P < .001). PICC complications occurred in 47 children (21.3%). No association was found between rural-urban continuum codes, driving times to the discharging hospital, or nearest trauma center with any complication nor with complications overall.

CONCLUSIONS

In our study, we demonstrate an equivalent safety profile for children in rural and urban settings with PICCs for receipt of outpatient PAT.

Being 'at-home' on outpatient parenteral antimicrobial therapy (OPAT): a qualitative study of parents' experiences of paediatric OPAT

OBJECTIVE

To better understand the factors that facilitate and hinder a positive experience of paediatric outpatient parenteral antimicrobial therapy (OPAT).

DESIGN

Qualitative study using semistructured interviews.

SETTING

A dedicated paediatric consultant-led hospital-based, outreach OPAT service in England.

PARTICIPANTS

Participants were primarily parents of children who had received OPAT; one child participated.

METHODS

Children and parents of children who received OPAT and who had participated in the survey phase of the larger study were invited to be interviewed.

RESULTS

12 parents (10 mothers and 2 fathers) of 10 children participated; one child (aged 15 years). Data analysis resulted in one meta-theme, 'At-homeness' with OPAT, this reflected the overall sense of home being a place in which the children and their parents could be where they wanted to be. Four key themes were identified that reflect the ways in which parents and children experienced being at-home on OPAT: 'Comfort, security, freedom, and control'; 'Faith, trust and confidence'; 'Explanations and communication' and 'Concerns, restrictions and inconveniences'.

CONCLUSIONS

Despite feeling anxious at times, parents reported that they and their children generally had a positive experience of OPAT; being at-home brought many benefits compared with in-patient care. Recommendations arising from the study include a 'whole-system' approach to discharge home that includes support related to return to school/nursery, reduction in disruptions to home-based routines, more clarity on choice and preparation for managing potential anxiety, better consideration of dose timing and enhanced preparation and information.

2018 Infectious Diseases Society of America Clinical Practice Guideline for the Management of Outpatient Parenteral Antimicrobial Therapy

A panel of experts was convened by the Infectious Diseases Society of America (IDSA) to update the 2004 clinical practice guideline on outpatient parenteral antimicrobial therapy (OPAT) [1]. This guideline is intended to provide insight for healthcare professionals who prescribe and oversee the provision of OPAT. It considers various patient features, infusion catheter issues, monitoring questions, and antimicrobial stewardship concerns. It does not offer recommendations on the treatment of specific infections. The reader is referred to disease- or organism-specific guidelines for such support.

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.

Daily outpatient intravenous antibiotic therapy for the management of paediatric periorbital cellulitis, a retrospective case series

OBJECTIVE

To evaluate whether outpatient treatment of periorbital cellulitis with daily administration of intravenous antibiotics and physician evaluation is an effective and safe alternative to admission.

DESIGN

A retrospective chart review study of paediatric patients treated on an outpatient basis for periorbital cellulitis at a tertiary children's hospital between 2013 and 2015 was performed. Children were assessed day by a paediatrician to monitor for resolution of symptoms or complications.

SETTING

The Montreal Children's hospital, a tertiary care centre.

PARTICIPANTS

Children diagnosed with an uncomplicated periorbital cellulitis secondary to an acute sinusitis or upper respiratory tract infection.

MAIN OUTCOME MEASURES

The number of days of intravenous antibiotics, complications or need for subsequent admission. Complications were defined as formation of an abscess or phlegmon confirmed on computerised tomography scan, worsening or recurrent persistent cellulitis, failure to improve on intravenous antibiotics, and intracranial complications.

RESULTS

Sixty-six children with a diagnosis of uncomplicated periorbital cellulitis secondary to sinusitis who received intravenous antibiotics via medical day hospital and who fit the inclusion criteria were identified. The mean duration of intravenous antibiotic therapy was 4.1 days. All children received ceftriaxone, with one patient also receiving cefuroxime. Two of 66 patients developed complications; one patient required admission for failure to improve/subperiosteal phlegmon and later underwent functional endoscopic sinus surgery, and one patient developed an eyelid abscess that did not require admission. No patients developed severe neurological or visual deficits.

CONCLUSIONS

Outpatient intravenous therapy with daily reassessment by a physician may be a safe alternative to admission in select cases of periorbital cellulitis without systemic signs of illness.

Delivery, setting and outcomes of paediatric Outpatient Parenteral Antimicrobial Therapy (OPAT): a scoping review

BACKGROUND

There has been little detailed systematic consideration of the delivery, setting and outcomes of paediatric Outpatient Parenteral Antimicrobial Therapy (OPAT), although individual studies report that it is a safe and effective treatment.

OBJECTIVE

This scoping review aimed to examine what is known about the delivery, settings and outcomes of paediatric OPAT and to identify key knowledge deficits.

DESIGN

A scoping review using Arksey and O'Malley's framework was undertaken.

DATA SOURCES

Keywords were identified and used to search MEDLINE and CINAHL.

STUDY APPRAISAL METHODS

Primary research studies were included if samples comprised children and young people 21 or under, who had received OPAT at home or in a day treatment centre. The Mixed Methods Appraisal Tool was used to review the methodological quality of the studies MAIN FINDINGS: From a preliminary pool of 157 articles, 51 papers were selected for full review. 19 studies fitted the inclusion criteria. Factors influencing delivery of OPAT were diverse and included child's condition, home environment, child-related factors, parental compliance, training and monitoring. There is little consensus as to what constitutes success of and adverse events in OPAT.

CONCLUSIONS

Future studies need to clearly define and use success indicators and adverse events in order to provide evidence that paediatric OPAT is safe and effective.

IMPLICATIONS

Consensus outcomes that include child and parent perspectives need to be developed to allow a clearer appreciation of a successful paediatric OPAT service.

Safety and effectiveness of 'hospital in the home' and 'outpatient parenteral antimicrobial therapy' in different age groups: A systematic review of observational studies

OBJECTIVE

The aim of this study was .to systematically review the published literature of observational studies evaluating the safety and effectiveness of hospital in the home (HITH) and outpatient parenteral antimicrobial therapy (OPAT) in the general population, older people and children.

STUDY DESIGN

The review included retrospective studies and prospective studies performed on HITH and OPAT within different age groups. Only the studies that analysed the safety and effectiveness of HITH and OPAT were included for review.

DATA SOURCES

A literature search of electronic databases CINAHL, Web of Science, PubMed and SCOPUS from 1997 to 2016 was performed.

DATA SYNTHESIS

Forty-four studies met the inclusion criteria. Five studies were undertaken on HITH within the general population, 26 studies were undertaken on OPAT within the general population, 8 studies were on HITH and OPAT for older people and 5 studies were on OPAT with children. More than 88% of the studies reported a cure or treatment success rate of greater than 80%. Adverse events with drugs ranged from 0% to 30.2%; adverse events with vascular access devices ranged from 0% to 29%; readmission rate varied from 1% to 26%; mortality varied from 0% to 27.5%.

CONCLUSIONS

This review quantifies the rates of success and harm in real world practice, and demonstrates that while most patients experience treatment success, adverse events may be high in some groups. However, the methodologies used to measure these parameters were inconsistent and some demographic groups had only a small number of studies.

Hematopoiesis and the bacterial microbiome

Recent studies have revealed that the intestinal bacterial microbiome plays an important role in the regulation of hematopoiesis. A correlation between adverse hematologic effects and imbalance of the intestinal microbiome, or dysbiosis, is evident in several human conditions, such as inflammatory bowel disease, obesity, and, critically, in the setting of antibiotic exposure. Here we review the effects of gut dysbiosis on the hematological compartment and our current understanding of the mechanisms through which changes in the bacterial microbiome affect hematopoiesis.

Safety of Outpatient Parenteral Antimicrobial Therapy in Children

BACKGROUND AND OBJECTIVE

Outpatient parenteral antimicrobial therapy (OPAT) provides numerous benefits but may pose unique risks in children. We aimed to determine rates of OPAT antimicrobial- and intravenous access-related complications and their associations with specific antimicrobials and type of intravenous access in pediatric patients.

METHODS

Observational cohort study of patients receiving OPAT from August 2008 to May 2015 cared for by the Infectious Diseases service at a tertiary children's hospital. Primary outcome was antimicrobial discontinuation (AD) because of OPAT-associated complications. Secondary outcomes were unplanned outpatient healthcare visits and readmissions from OPAT-associated complications.

RESULTS

Seven hundred and seven intravenous antimicrobials were prescribed in 540 cases. Nondevice-associated musculoskeletal infection was the most common diagnosis (39%). Ceftriaxone (30%), cefazolin (27%) and vancomycin (22%) were the most commonly used antimicrobials. Complications led to AD, ≥1 unplanned outpatient healthcare visit and ≥1 readmission in 23%, 30% and 17% of cases, respectively. Compared with use of ceftriaxone, use of oxacillin was associated with a significantly higher risk of AD because of any antimicrobial-related complication [hazard ratio (HR), 3.3; 95% confidence interval (CI): 1.2-9.7) and because of hepatic transaminitis (HR, 32.8; 95% CI: 4.02-268.2). Subjects treated with intravenous clindamycin (HR, 2.6; 95% CI: 1.1-5.8) and with a peripherally inserted central catheter (HR, 2.6; 95% CI: 1.04-6.3) were more likely to have unplanned outpatient visits.

CONCLUSIONS

Use of oxacillin during OPAT was associated with higher rate of AD. Patients treated with clindamycin and those with a peripherally inserted central catheter had higher rates of unplanned outpatient visits. Providers should strongly consider alternative treatment options when possible.

Dedicated paediatric Outpatient Parenteral Antimicrobial Therapy medical support: a pre-post observational study

OBJECTIVE

Despite the many benefits of paediatric Outpatient Parenteral Antimicrobial Therapy (OPAT) programmes, there are risks associated with delivering inpatient-level care outside of hospital. There is a paucity of evidence defining how best to mitigate these risks. We examined the impact of introducing a dedicated medical team to OPAT, to define the role of increased medical oversight in improving patient outcomes in this cohort.

DESIGN

A prospective 24-month pre-post observational cohort study.

SETTING

The Hospital in the Home (HiTH) programme at Princess Margaret Hospital (PMH) for Children, Western Australia.

PATIENTS

All OPAT admissions to HiTH, excluding haematology/oncology patients.

INTERVENTIONS

PMH introduced a dedicated OPAT medical support team in July 2015 to improve adherence to best-practice guidelines for patient monitoring and review.

MAIN OUTCOME MEASURES

Duration of OPAT, adherence to monitoring guidelines, drug-related and line-related adverse events and readmission to hospital.

RESULTS

There were a total of 502 OPAT episodes over 24 months, with 407 episodes included in analyses. Following the introduction of the OPAT medical team, adherence to monitoring guidelines improved (OR 4.90, 95% CI 2.48 to 9.66); significantly fewer patients required readmission to hospital (OR 0.45, 95% CI 0.24 to 0.86) and there was a significant reduction in the proportion of patients receiving prolonged (≥7 days) OPAT (OR 0.67, 95% CI 0.45 to 0.99).

CONCLUSION

The introduction of a formal medical team to HiTH demonstrated a positive clinical impact on OPAT patients' outcomes. These findings support the ongoing utility of medical governance in a nurse-led HiTH service.

Adverse Events in Pediatric Patients Receiving Long-term Oral and Intravenous Antibiotics

BACKGROUND AND OBJECTIVE

Children receiving long-term antibiotic therapy (LTAT) at Children's Hospital Colorado (CHCO) are treated with both oral and intravenous (i.v.) agents and often experience complications not comprehensively described by the literature. We sought to describe adverse drug events (ADEs) and venous access complications (VACs) in pediatric patients managed with oral and i.v. antibiotics so as to inform clinical decision-making, drug monitoring, and patient counseling at CHCO.

METHODS

We conducted a retrospective review of children receiving LTAT through the CHCO infectious disease service from 2006 to 2012. Demographic, microbiologic, diagnostic data, ADEs, and VACs were recorded for each patient.

RESULTS

From 2006 to 2012, 521 patients received 1876 courses, accounting for 71,306 days of antimicrobial therapy. A total of 219 patients (42%) developed an ADE with discontinuation of the offending agent in 65% of courses associated with an ADE. The most common ADEs were neutropenia, rash, and diarrhea. Central lines were placed in 376 patients with 106 (28%) experiencing ≥1 VACs. I.v. agents were associated with a fourfold increase in the rate of ADEs compared with oral agents, and a fivefold increase when VACs were included.

CONCLUSIONS

Practitioners may make more informed decisions and risk assessments by using descriptive ADE information for specific agents and mode of drug delivery to mitigate risk, thereby improving the quality of care. Patients should be counseled regarding risks of LTAT, including increased risk with i.v. therapy, and actively monitored for side effects.

An Approach to the Management of Pleural Empyema with Early Video-assisted Thoracoscopic Surgery and Early Transition to Oral Antibiotic Therapy

Practice variation exists in the management of children with bacterial pneumonia complicated by empyema. The success of video-assisted thoracoscopic surgery (VATS) versus chest tube insertion for drainage and fibrinolysis may be dependent on the stage of disease. There is little published experience with early transition to oral (PO) antibiotics, and many children are treated with intravenous (IV) antibiotics at home. To describe a cohort of children with pneumonia and empyema in a primarily rural state managed with early VATS and transition to PO antibiotics. This was a retrospective medical record review of children managed by the pediatric infectious diseases and surgery services at Kosair Children's Hospital from 2008 through 2012. Sixty-one children met inclusion criteria. The majority underwent VATS on the first or second hospital day. No organism was identified in 67 per cent of cases. All patients received IVantibiotics at admission and all were discharged on PO antibiotics. The median time to transition was five days (interquartile range [IQR], 4–6), and the median duration of PO therapy was 16 days (IQR, 14–21). Ninety-eight per cent did not require further IV therapy. There were no deaths and clinical outcomes were good. In conclusion, children with pneumonia and empyema can be managed effectively with early VATS and early transition from IV to PO antibiotic therapy.

Oral Ambulatory Treatment of Acute Osteomyelitis in Children: A Case-Control Study

The treatment of acute hematogenous osteomyelitis has evolved in recent years to a shorter parenteral treatment with an early switch to the oral route. Current publications recommend a 2- to 4-day parenteral treatment before the oral switch. We retrospectively analyzed a series of 45 children aged 1 to 11 years and treated in our department for acute osteomyelitis without severity criterion. Nineteen of 45 patients were treated by an exclusive ambulatory oral treatment by amoxicillin and clavulanic acid. Twenty six of 45 patients had a 2- to 4-day parenteral treatment before the oral switch. The minimum follow-up was 6 months. The primary endpoint was a clinical, radiographic, and biologic healing, 6 months after the beginning of the treatment. The secondary endpoints evaluated were the length of hospitalization, the total duration of treatment, and the type of antibiotic used. On the primary endpoint, we did not find any significant difference between the 2 treatments (P = 0.38). On the duration of treatment, we found a significant difference (P = 0.049) in favor of oral treatment. The ambulatory oral treatment by amoxicillin and clavulanic acid seems to be a valid alternative to the classical parenteral then oral sequence in the treatment of acute hematogenous osteomyelitis in children without severity criterion.

Adverse Events in Pediatric Patients Receiving Long-Term Outpatient Antimicrobials

BACKGROUND

Although long treatment courses of outpatient antimicrobials are often used in pediatric patients, few data exist regarding the frequency of adverse events (AEs) associated with these medications.

METHODS

We performed a retrospective cohort study of all patients seen in the Infectious Diseases clinic at a tertiary referral children's hospital from August 1, 2009 to August 1, 2011. We included patients who received ≥14 days of oral or intravenous antibiotic, antiviral, or antifungal medications. Patients receiving only prophylactic medications or human immunodeficiency virus treatment were excluded.

RESULTS

Three hundred thirty-five subjects met inclusion criteria, with a median age of 7.4 years at start of therapy. The cohort was predominantly male (60%), white (54%), and previously healthy (59%). A majority (88.4%) of subjects were treated for bacterial infections. β-Lactam agents were the most commonly used antimicrobial class (210 subjects; 62.7%), followed by clindamycin (86; 25.7%), rifampin (76; 22.7%), and vancomycin (62; 18.5%). Overall, 107 (31.9%) subjects experienced 151 distinct AEs. The most common individual AE noted was diarrhea (44; 29.1% of all AEs). Serious AEs developed in 42 (12.5%) subjects, including allergic reactions (15; 11.3% of all AEs), venous catheter-related complications (14; 13.0% of those with catheters), neutropenia (9; 3.0%), renal insufficiency (7; 2.5%), and hepatotoxicity (3; 1.1%). Rates of AEs were similar between those on oral and intravenous antimicrobials.

CONCLUSIONS

In our study population, patients on prolonged oral or intravenous outpatient antimicrobials experienced AEs frequently. These findings support the need for close monitoring of pediatric patients on prolonged antimicrobial therapy and vigilance for unwanted effects of these medications.

Prediction model for 30-day hospital readmissions among patients discharged receiving outpatient parenteral antibiotic therapy

BACKGROUND

Factors associated with readmission for patients prescribed outpatient parenteral antibiotic therapy (OPAT) at hospital discharge have not been definitively identified. The study aim was to develop a model of 30-day readmissions for OPAT patients.

METHODS

A database comprising 782 OPAT patients treated between 2009 and 2011 at a single academic center was created. Variables collected included patient demographics, comorbidities, infections, and antibiotic classes. Final model discrimination was assessed using the c-statistic, and calibration was examined graphically.

RESULTS

Mean patient age was 58 years (range, 18-95 years), 43% were women, and the most common diagnoses were bacteremia (24%), osteomyelitis (20%), and pyelonephritis (13%). The unplanned 30-day readmission rate was 26%. The leading indications for readmission were non-infection related (30%), worsening infection (29%), and new infection (19%). The final regression model consisted of age (odds ratio [OR], 1.09 per decade; 95% confidence interval [CI], 0.99-1.21), aminoglycoside use (OR, 2.33; 95% CI, 1.17-4.57), resistant organisms (OR, 1.57; 95% CI, 1.03-2.36), and number of prior hospital discharges without intravenous antibiotics in the past 12 months (OR, 1.20 per prior admission; 95% CI, 1.09-1.32). The c-statistic was 0.61 and the highest-risk quintile of patients had almost a 3-fold higher rate of readmission compared to the lowest.

CONCLUSIONS

Patients prescribed OPAT are at risk for readmission. A subgroup of patients at especially high risk can be identified using easily obtainable clinical characteristics at the time of hospital discharge. More intensive interventions to prevent OPAT readmissions should be targeted and tested with those at highest risk.

[Domiciliary parenteral antibiotic therapy: a prospective analysis of the last 12 years]

OBJETIVES

Parenteral antibiotic treatment has been classically developed in hospitals and is considered as a hospital procedure. The development of Hospital at Home Units (HHU) has led to an increase in outpatient parenteral antibiotic therapy (OPAT) in paediatrics patients. The objective of this study is to describe our experience, as an HHU integrated within a Paediatric Department, in home antimicrobial therapy over a period of 12 years.

PATIENTS AND METHODS

This prospective and descriptive study included every patient with a disease requiring parenteral antimicrobial therapy who was admitted to our HHU from January 2000 to December 2012.

RESULTS

During the study there were 163 cases on OPAT. The mean age of the patients was 11.1 years, and the sample group was comprised of 33 males and 22 feamales. The main sources of the treated infections were respiratory tract (76%), catheter-related bloodstream (9.2%), and urinary tract infections (5.5%). Amikacin was the most widely used antibiotic. Almost all treatments (96.6%) were via an intravenous route. Catheter-associated complications were more common than drug-associated complications. Successful at-home treatment was observed in 90.2% of cases.

CONCLUSIONS

OPAT is a good and safe alternative in many paediatric diseases.

Characteristics and outcomes of outpatient parenteral antimicrobial therapy at an academic children's hospital

BACKGROUND

Use of outpatient parenteral antimicrobial therapy (OPAT) in pediatrics is widespread and may be increasing. Recent data quantifying use and characteristics of pediatric OPAT are lacking.

METHODS

To evaluate the number of children receiving OPAT each year and their associated characteristics and outcomes, we conducted a retrospective review of all patients discharged with OPAT from the Mayo Clinic Children's Hospital between August 1, 2010 and December 31, 2011.

RESULTS

During the study period, there were 126 pediatric hospital discharges with OPAT (2.5% of all discharges). OPAT was used most commonly to treat bone and joint (21%), bloodstream (15%), intra-abdominal (13%) and soft tissue (9%) infections. A positive culture or serology result was found in 86 (68%) OPAT courses. The most frequently used antibiotics were ceftriaxone (17%), cefazolin (16%) and cefepime (13%). The median duration of OPAT was 12 days. Thirty-six courses (29%) resulted in catheter- or antibiotic-associated complications. Weekly laboratory monitoring was more common when OPAT was managed by the infectious disease service (88%) versus other services (20%). Among 123 courses with follow-up, 109 (89%) resulted in cure, and 13 (11%) were treatment failures.

CONCLUSION

At our children's hospital, 2.5% of hospitalized patients were discharged with OPAT. In one-third of OPAT courses children developed catheter- or antibiotic-associated complications. Opportunities to increase the role of pediatric infectious disease in OPAT initiation and management should be explored.
