Cost-minimization model of a multidisciplinary Antibiotic Stewardship Team based on a successful implementation on a urology ward of an academic hospital

BackgroundIn order to stimulate appropriate antimicrobial use and thereby lower the chances of resistance development, an Antibiotic Stewardship Team (A-Team) has been implemented at the University Medical Center Groningen, the Netherlands. Focus of the A-Team was a pro-active day 2 case-audit, which was financially evaluated here to calculate the return on investment from a hospital perspective.MethodsEffects were evaluated by comparing audited patients with a historic cohort with the same diagnosis-related groups. Based upon this evaluation a cost-minimization model was created that can be used to predict the financial effects of a day 2 case-audit. Sensitivity analyses were performed to deal with uncertainties. Finally, the model was used to financially evaluate the A-Team.ResultsOne whole year including 114 patients was evaluated. Implementation costs were calculated to be (sic)17,732, which represent total costs spent to implement this A-Team. For this specific patient group admitted to a urology ward and consulted on day 2 by the A-Team, the model estimated total savings of (sic)60,306 after one year for this single department, leading to a return on investment of 5.9.ConclusionsThe implemented multi-disciplinary A-Team performing a day 2 case-audit in the hospital had a positive return on investment caused by a reduced length of stay due to a more appropriate antibiotic therapy. Based on the extensive data analysis, a model of this intervention could be constructed. This model could be used by other institutions, using their own data to estimate the effects of a day 2 case-audit in their hospital.</p

Yield of yearly routine physical examination in HIV-1 infected patients is limited:A retrospective cohort study in the Netherlands

Background Routine physical examinations might be of value in HIV-infected patients, but the yield is unknown. We determined the diagnoses that would have been missed without performing annual routine physical examinations in HIV-infected patients with stable disease. Methods Data were collected from the medical records of 299 HIV-1-infected patients with CD4 count >350 cells/mm(3) if not using combination antiretroviral therapy (cART), or CD4 count >100 cells/mm3 and undetectable viral load if using cART. We defined the diagnoses that would have been missed without performing routine physical examinations on annual check-ups in 2010. Exclusion criteria were hepatitis B/C co-infection, start/switch of cART Results 215 patients (72%) had positive findings: lipodystrophy (30%), lymphadenopathy (16%) and hypertension (8.4%) were the most common. Two-thirds of all findings were not new or were based on complaints indicating a physical examination even if not routinely scheduled. For 24 patients (8.0%) the routine physical examination led to the finding of a new diagnosis: six-all men who have sex with men (MSM)-had a concurrent sexually transmitted infection, eight had hypertension, and ten others had a large variety of diagnoses. A total atrioventricular block with bradycardia was the most clinically relevant finding. Conclusions Annual physical examinations of HIV-infected patients with stable disease brought few new diagnoses that would have been missed without performing a routine examination. Our results suggest that standard assessments could be restricted to six-monthly measuring blood pressure in all patients and annually performing anogenital and digital rectal examination on MSM

Automatic day-2 intervention by a multidisciplinary antimicrobial stewardship-team leads to multiple positive effects

BACKGROUND: Antimicrobial resistance rates are increasing. This is, among others, caused by incorrect or inappropriate use of antimicrobials. To target this, a multidisciplinary antimicrobial stewardship-team (A-Team) was implemented at the University Medical Center Groningen on a urology ward. Goal of this study is to evaluate the clinical effects of the case-audits done by this team, looking at length of stay (LOS) and antimicrobial use. METHODS: Automatic e-mail alerts were sent after 48 h of consecutive antimicrobial use triggering the case-audits, consisting of an A-Team member visiting the ward, discussing the patient's therapy with the bed-side physician and together deciding on further treatment based on available diagnostics and guidelines. Clinical effects of the audits were evaluated through an Interrupted Time Series analysis and a retrospective historic cohort. RESULTS: A significant systemic reduction of antimicrobial consumption for all patients on the ward, both with and without case-audits was observed. Furthermore, LOS for patients with case-audits who were admitted primarily due to infections decreased to 6.20 days (95% CI: 5.59-6.81) compared to the historic cohort (7.57 days; 95% CI: 6.92-8.21; p = 0.012). Antimicrobial consumption decreased for these patients from 8.17 DDD/patient (95% CI: 7.10-9.24) to 5.93 DDD/patient (95% CI: 5.02-6.83; p = 0.008). For patients with severe underlying diseases (e.g., cancer) these outcome measures remained unchanged. CONCLUSION: The evaluation showed a considerable positive impact. Antibiotic use of the whole ward was reduced, transcending the intervened patients. Furthermore, LOS and mean antimicrobial consumption for a subgroup was reduced, thereby improving patient care and potentially lowering resistance rates

'Bedside'-consultatie door multidisciplinair Antibiotica-team: 'Antimicrobial stewardship'-programma in het UMCG

In 2012, the Dutch Working Party on Antibiotic Policy (SWAB) published a vision document to counteract the rise in antibiotic use and resistance. An Antibiotic Stewardship Programme (ASP) will be implemented by a multidisciplinary antibiotics team (A-team). In 2012 University Medical Centre Groningen (UMCG) in the Netherlands started an Antibiotic Stewardship Programme (ASP) pilot project at the trauma surgery ward. The focus is on providing bedside consultation for patients based on the day 2 bundle. Implementation of the ASP on the basis of a day 2 bundle resulted in an intervention percentage of 75%. The pilot project was a success and will be extended to other wards
