The aim of this review is to synthesise the evidence base concerning the costs of hospital data collection for performance monitoring using key performance indicators (KPIs), and to identify hospital data collection systems that have proven to be cost-minimising. There are two main objectives:
To identify published economic evaluations and cost studies regarding hospital data collection for performance monitoring purposes; and
To identify and summarise the methods used to evaluate hospital data collection for performance monitoring purposes.
The main questions of this review are as follows:
What literature exists on the economic analysis of hospital data collection for performance monitoring purposes using KPIs?
Once identified, how do these studies measure the economic costs and health benefits of hospital data collection for performance monitoring purposes?
The research questions will be addressed using a systematic review of the qualitative and quantitative literature. The conclusions will then be summarised in a narrative review using the evidence found. The components of this systematic review are:
All economic analysis and costing studies regarding hospital data collection for performance monitoring purposes will be included in the review. See Additional file 1: Table S1 for the inclusion criteria form.
Types of studies
The types of studies that are to be identified are economic evaluations and cost or feasibility studies regarding hospital data collection for performance monitoring purposes using KPIs. For the purpose of this review, the definition of KPI will include any variable or a synonym of an indicator used to measure key areas of a service for performance monitoring purposes. Therefore, studies examining quality-of-care indicators and clinical indicators will be screened for inclusion.
Types of participant
There are broadly speaking two types of participant that are routinely involved in hospital data collection systems for performance monitoring: clinical (doctors, nurses, and allied health professionals, such as physiotherapists, respiratory therapists and occupational therapists) and non-clinical staff (for example, administrators, clerical staff, managers and information technology staff).
Types of interventions
Hospitals may have varied ways of recording and collecting data for performance monitoring purposes using KPIs. All types of interventions (as defined by the study authors) that are used to record and collect data will be included in this review.
Studies that will be excluded from the review will be those cost and economic analyses and feasibility studies that do not focus on data collection in the hospital setting.
To identify relevant research, a search strategy has been produced and can be found in Additional file 2: Table S2. The search strategy will then be applied to appropriate databases to search for potentially eligible studies. Databases that will be searched include Medline, Embase and CINAHL via the Ovid SP website. The titles and abstracts of all identified studies potentially eligible for inclusion in the review will be searched. Full-text versions of these potentially eligible studies will be obtained. Additional efforts to identify more potentially eligible studies for inclusion will be made from the following data sources:
Reference lists from included studies; and
Published reports by the Departments of Health based in the United Kingdom, Ireland, the United States, Canada and Australia.
Methods for study selection
The screening process for study selection will be completed in two stages. Stage one will include screening the titles and abstracts of each publication against the inclusion criteria. The studies that will be selected for the review will meet all of the inclusion criteria requirements. Stage two will involve screening the full-text version of the publication to confirm whether or not the study should be included in the final review. Stages one and two will be conducted by two investigators (BG and CJ) independently, and a comparison of included and excluded studies will be carried out. If there are discrepancies with any inclusion or exclusion decisions, and the two investigators who independently screen potentially eligible studies cannot reach a consensus, the disagreements will be resolved through discussion and consultation with a third reviewer (AW).
Primary abstract screening
An inclusion/exclusion form (see Additional file 1: Table S1) will be used to initially determine whether or not a study meets the requirements to satisfy inclusion based on reading the Abstract and Conclusion sections. Initial inclusion criteria will consist of:
Economic evaluations that address the cost of hospital data collection for performance monitoring using KPIs; and
Studies published in English.
If it is not clear whether a study will be rejected by the reviewers from the initial screening of the title and abstract, the full text will be obtained and further evaluation of the study will be carried out.
Methods for data extraction
One author (CJ) will extract data using a tailored data collection form that includes information concerning the name of the first author, year of publication, study design, study population and study setting. A second investigator (BG) will then verify the extracted data. Data that will be extracted from studies will include cost data, potential health benefits, data collection systems that have been/are used and if any of these systems have been found to be cost minimising. See Additional file 3: Table S3 for the full list of information that will be extracted.
Each study identified will be assessed for its quality using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) guidelines published by the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) (CHEERS, ) (see Additional file 4: Table S4 for full list). One researcher (CJ) will conduct the quality assessment and a second researcher (BG) will review and highlight any discrepancies. If there are discrepancies concerning quality assessment decisions and the two investigators performing the assessment cannot reach a consensus, the disagreements will be resolved through discussion and consultation with a third reviewer (AW).
Data will not be synthesised using quantitative techniques. The extracted data will be summarised in tables and a narrative review will be prepared. This will include an assessment of what systems hospitals currently use to collect data for the purpose of performance monitoring using KPIs, a description of the alternative (traditional) systems used to collect data and a description of the costs and benefits associated with hospital data collection.
A subgroup analysis will be performed on hospital data collection for performance monitoring purposes in the emergency care setting versus the non-emergency care setting, because hospital-provided care can be broadly divided into these two categories.
