Standardised mortality ratios as a user-friendly performance metric and trigger for quality improvement in a Flemish hospital network: multicentre retrospective study.

ABSTRACT:

Objective

To illustrate the development and use of standardised mortality rates (SMRs) as a trigger for quality improvement in a network of 27 hospitals.

Design

This research was a retrospective observational study. The primary outcome was in-hospital mortality. SMRs were calculated for All Patient Refined-Diagnosis-Related Groups (APR-DRGs) that reflect 80% of the Flemish hospital network mortality. Hospital mortality was modelled using logistic regression. The metrics were communicated to the member hospitals using a custom-made R-Shiny web application showing results at the level of the hospital, patient groups and individual patients. Experiences with the metric and strategies for improvement were shared in chief medical officer meetings organised by the Flemish hospital network.

Setting

27 Belgian hospitals.

Participants

1 198 717 hospital admissions for registration years 2009-2016.

Results

Patient gender, age, comorbidity as well as admission source and type were important predictors of mortality. Altogether the SMR models had a C-statistic of 88%, indicating good discriminatory capability. Seven out of ten APR-DRGs with the highest percentage of hospitals statistically significantly deviating from the benchmark involved malignancy. The custom-built web application and the trusted environment of the Flemish hospital network created an interoperable strategy to get to work with SMR findings. Use of the web application increased over time, with peaks before and after key discussion meetings within the Flemish hospital network. A concomitant reduction in crude mortality for the selected APR-DRGs from 6.7% in 2009 to 5.9% in 2016 was observed.

Conclusions

This study reported on the phased approach for introducing SMR reporting to trigger quality improvement. Prerequisites for the successful use of quality metrics in hospital benchmarks are a collaborative approach based on trust among the participants and a reporting platform that allows stakeholders to interpret and analyse the results at multiple levels.

Project description:Clinical Handover remains one of the most perilous procedures in medicine (1). Weekend handover has emerged as a key area of concern with high variability in handover processes across hospitals (1,2,4, 5-10). Studying weekend handover processes within medicine at an acute teaching hospital revealed huge variability in documented content and structure. A total of 12 different pro formas were in use by the medical day-team to handover to the weekend team on-call. A Likert-survey of doctors revealed 93% felt the current handover system needed improvement with 71% stating that it did not ensure patient safety (Chi-squared, p-value <0.001, n=32). Semi-structured interviews of doctors identified common themes including "a lack of consistency in approach" "poor standardization" and "high variability". Seeking to address concerns of standardization, a standardized handover pro forma was developed using Royal College of Physician (RCP) guidelines (2), with direct end-user input. Results following implementation revealed a considerable improvement in documented ceiling of care, urgency of task and team member assignment with 100% uptake of the new proforma at both 4-week and 6-month post-implementation analyses. 88% of doctors surveyed perceived that the new proforma improved patient safety (p<0.01, n=25), with 62% highlighting that it allowed doctors to work more efficiently. Results also revealed that 44% felt further improvements were needed and highlighted electronic solutions and handover training as main priorities. Handover briefing was subsequently incorporated into junior doctor induction and education modules delivered, with good feedback. Following collaboration with key stakeholders and with end-user input, integrated electronic handover software was designed and funding secured. The software is currently under final development. Introducing a standardized handover proforma can be an effective initial step in improving weekend handover. Handover education and end-user involvement are key in improving the process. Electronic handover solutions have been shown to significantly increase the quality of handover and are worth considering (9, 10).

Project description:Genotyping by re-sequencing has become a standard approach to estimate single nucleotide polymorphism (SNP) diversity, haplotype structure and the biodiversity and has been defined as an efficient approach to address geographical population genomics of several model species. To access core SNPs and insertion/deletion polymorphisms (indels), and to infer the phyletic patterns of speciation, most such approaches map short reads to the reference genome. Variant calling is important to establish patterns of genome-wide association studies (GWAS) for quantitative trait loci (QTLs), and to determine the population and haplotype structure based on SNPs, thus allowing content-dependent trait and evolutionary analysis. Several tools have been developed to investigate such polymorphisms as well as more complex genomic rearrangements such as copy number variations, presence/absence variations and large deletions. The programs available for this purpose have different strengths (e.g. accuracy, sensitivity and specificity) and weaknesses (e.g. low computation speed, complex installation procedure and absence of a user-friendly interface). Here we introduce Altools, a software package that is easy to install and use, which allows the precise detection of polymorphisms and structural variations.Altools uses the BWA/SAMtools/VarScan pipeline to call SNPs and indels, and the dnaCopy algorithm to achieve genome segmentation according to local coverage differences in order to identify copy number variations. It also uses insert size information from the alignment of paired-end reads and detects potential large deletions. A double mapping approach (BWA/BLASTn) identifies precise breakpoints while ensuring rapid elaboration. Finally, Altools implements several processes that yield deeper insight into the genes affected by the detected polymorphisms. Altools was used to analyse both simulated and real next-generation sequencing (NGS) data and performed satisfactorily in terms of positive predictive values, sensitivity, the identification of large deletion breakpoints and copy number detection.Altools is fast, reliable and easy to use for the mining of NGS data. The software package also attempts to link identified polymorphisms and structural variants to their biological functions thus providing more valuable information than similar tools.
