ABSTRACT The Clinical and Laboratory Standards Institute antimicrobial and antifungal standards define a susceptible-dose-dependent (SDD) category for certain organisms and drug combinations. Reporting MICs within the SDD category suggests that treatment success is likely with increased drug exposure. These breakpoints are based on pharmacokinetic, pharmacodynamic, and clinical outcome data from adults and not pediatric patients. This commentary aims to discuss the implications of reporting SDD interpretations for pediatric patients and recommends laboratory reporting comments.

ABSTRACT Breakpoints are used to predict whether an antifungal agent will be clinically effective against a particular fungal isolate. They are based on a combination of MIC values, pharmacokinetic/pharmacodynamic values, and clinical outcome data. For many fungus-antifungal combinations, these data might never be available. For these combinations, epidemiological cutoff values (ECVs) provide a methodology for categorizing isolates as either wild type (WT) or non-WT. In this review, we define ECVs, explain how they are generated using the CLSI methodology in standard M57, and describe how they can be used in clinical practice.

Purpose The purpose of this paper is to analyse the clinical outcome data collected as part of an 18-week, abstinence-based residential therapeutic community (TC) programme, Higher Ground Drug Rehabilitation Trust (Higher Ground) in New Zealand. Lessons and implications for routine collection of clinical outcome data are identified. Design/methodology/approach Higher Ground collects longitudinal data on all consenting clients using a battery of validated psychometric tools, with repeated measures at up to nine points in time from first presentation through to 12-month post-discharge follow up. Data analysis covered clients who entered Higher Ground between 1 July 2012 and 2 June 2015 (n=524). Findings Clients presented with histories of addiction which often had significant negative associations with their physical and psychological health, their relationships, work, accommodation and criminal behaviour. By the time they exited the programme, clinically and statistically significant improvements were seen across multiple indicators including: substance use and abstinence; symptoms of post-traumatic stress disorder, depression, anxiety and stress; and a range of social indicators. Research limitations/implications Attrition in follow-up research is a significant challenge, with people completing the TC programme being more likely to participate than those who do not. This limits generalizability in post-discharge data. There was no control group, making causal attribution a challenge. Identifying suitable benchmarks from the literature is challenging because of the variety of outcome measures and research methodologies used. Practical implications Tracking client outcomes longitudinally using psychometric tools is potentially valuable for TCs and their funding bodies, as it provides insights into patterns of client recovery that can inform ongoing service improvements and resource allocation decisions. However, significant challenges remain. Originality/value The study demonstrates the value, and practical challenges, of collecting high-quality outcome data in a TC setting.
