How representative is the Victorian Emergency Minimum Dataset (VEMD) for population-based injury surveillance in Victoria? A retrospective observational study of administrative healthcare data.

ABSTRACT:

Objective

The Victorian Emergency Minimum Dataset (VEMD) is a key data resource for injury surveillance. The VEMD collects emergency department data from 39 public hospitals across Victoria; however, rural emergency care services are not well captured. The aim of this study is to determine the representativeness of the VEMD for injury surveillance.

Design

A retrospective observational study of administrative healthcare data.

Setting and participants

Injury admissions in 2014/2015-2018/2019 were extracted from the Victorian Admitted Episodes Dataset (VAED) which captures all Victorian hospital admissions; only cases that arrived through a hospital's emergency department (ED) were included. Each admission was categorised as taking place in a VEMD-contributing versus a non-VEMD hospital.

Results

There were 535 477 incident injury admissions in the study period, of which 517 207 (96.6%) were admitted to a VEMD contributing hospital. Male gender (OR 1.13 (95% CI 1.10 to 1.17)) and young age (age 0-14 vs 45-54 years, OR 4.68 (95% CI 3.52 to 6.21)) were associated with VEMD participating (vs non-VEMD-participating) hospitals. Residing in regional/rural areas was negatively associated with VEMD participating (vs non-VEMD participating) hospitals (OR=0.11 (95% CI 0.10 to 0.11)). Intentional injury (assault and self-harm) was also associated with VEMD participation.

Conclusions

VEMD representativeness is largely consistent across the whole of Victoria, but varies vastly by region, with substantial under-representation of some areas of Victoria. By comparison, for injury surveillance, regional rates are more reliable when based on the VAED. For local ED-presentation rates, the bias analysis results can be used to create weights, as a temporary solution until rural emergency services injury data is systematically collected and included in state-wide injury surveillance databases.

Project description:This data relates to existing and planned electricity generation projects in Victoria, Australia. Planning Victoria, part of the Victorian Government, registered most projects. The technical performance data for the projects includes the electricity generated, input fuel, losses in the transmission of electricity, energy storage options, and transparency between grid operators and stakeholders. The social data related to the projects include health data for the effect of Victorian coal plant pollution, including a rich dataset on the health effects of a coal fire in (Jennens, 2021). A dataset for all the health effects of coal plants in Victoria was then compiled. The social data also includes a measure of customer engagement with electricity distribution companies in Victoria and public satisfaction with renewable projects in Victoria. The economic cost data includes capital costs, operation and maintenance costs, and externality costs related to greenhouse gasses emitted. The environmental data used a life cycle assessment and the critical materials needed for the electricity generation projects. The analysis performed was an nBL assessment (Foliente, 2007) which uses a comparative analysis of the four bottom lines (environmental, social, economic and technology). An nBL assessment is similar to a Triple Bottom Line assessment but includes additional parameters. The data used for this nBL analysis was for three scenarios (business as usual, a renewable generation future with electricity imported from other states and a renewable generation future with all electricity generated in Victoria). The first step in managing the raw data was to normalise, standardise and aggregate the data. These steps were done for the four bottom lines and the three scenarios. The reuse potential of this data is high as it is for a pipeline of projects that will continue to evolve. This data would also have the potential for other researchers to compare the Victorian electricity transition with other places internationally.

Project description:BackgroundThe National Disaster Management Agency (Badan Nasional Penanggulangan Bencana) handles disaster management in Indonesia as a health cluster by collecting, storing, and reporting information on the state of survivors and their health from various sources during disasters. Data were collected on paper and transferred to Microsoft Excel spreadsheets. These activities are challenging because there are no standards for data collection. The World Health Organization (WHO) introduced a standard for health data collection during disasters for emergency medical teams (EMTs) in the form of a minimum dataset (MDS). Meanwhile, the Ministry of Health of Indonesia launched the SATUSEHAT platform to integrate all electronic medical records in Indonesia based on Fast Healthcare Interoperability Resources (FHIR).ObjectiveThis study aims to implement the WHO EMT MDS to create a disaster profile for the SATUSEHAT platform using FHIR.MethodsWe extracted variables from 2 EMT MDS medical records-the WHO and Association of Southeast Asian Nations (ASEAN) versions-and the daily reporting form. We then performed a mapping process to match these variables with the FHIR resources and analyzed the gaps between the variables and base resources. Next, we conducted profiling to see if there were any changes in the selected resources and created extensions to fill the gap using the Forge application. Subsequently, the profile was implemented using an open-source FHIR server.ResultsThe total numbers of variables extracted from the WHO EMT MDS, ASEAN EMT MDS, and daily reporting forms were 30, 32, and 46, with the percentage of variables matching FHIR resources being 100% (30/30), 97% (31/32), and 85% (39/46), respectively. From the 40 resources available in the FHIR ID core, we used 10, 14, and 9 for the WHO EMT MDS, ASEAN EMT MDS, and daily reporting form, respectively. Based on the gap analysis, we found 4 variables in the daily reporting form that were not covered by the resources. Thus, we created extensions to address this gap.ConclusionsWe successfully created a disaster profile that can be used as a disaster case for the SATUSEHAT platform. This profile may standardize health data collection during disasters.

Project description:Healthcare administrative (claims) data are commonly utilized to estimate drug effects. We identified considerable heterogeneity in fracture outcome definitions in a scoping review of 57 studies that estimated osteoporosis drug effects on fracture risk. Better understanding of the impact of different fracture definitions on study results is needed.PurposeHealthcare administrative (claims) data are frequently used to estimate the real-world effects of drugs. Fracture incidence is a common outcome of osteoporosis drug studies. We aimed to describe how fractures are defined in studies that use claims data.MethodsWe searched MEDLINE (Ovid), Embase (Ovid), CINAHL (EBSCO), and gray literature for studies published in English between 2000 and 2020 that estimated fracture effectiveness (hip, humerus, radius/ulna, vertebra) or safety (atypical fracture of the femur, AFF) of osteoporosis drugs using claims data in Canada and the USA. Literature searches, screening and data abstraction were completed independently by two reviewers.ResultsWe identified 57 eligible studies (52 effectiveness, 3 safety, 2 both). Hip fracture was the most common fracture site studied (93%), followed by humerus (66%), radius/ulna (59%), vertebra (61%), and AFF (9%). Half (n = 29) of the studies did not indicate specific data sources, codes, or cite a validation paper. Of the papers with sufficient detail, heterogeneity in fracture definitions was common. The most common definition within each fracture site was used by less than half of the studies that examined effectiveness (12 definitions in 29 hip fracture papers, 8 definitions in 17 humerus papers, 8 definitions in 13 radius/ulna papers, 9 definitions in 15 vertebra papers), and 3 definitions among 4 AFF papers.ConclusionThere is ambiguity and heterogeneity in fracture outcome definitions in studies that leverage claims data. Better transparency in outcome reporting is needed. Future exploration of how fracture definitions impact study results is warranted.

Project description:BackgroundThe municipalities are responsible for the emergency primary health care services in Norway. These services include casualty clinics, primary doctors on-call and local emergency medical communication centres (LEMC). The National centre for emergency primary health care has initiated an enterprise called "The Watchtowers", comprising emergency primary health care districts, to provide routine information (patients' way of contact, level of urgency and first action taken by the out-of-hours services) over several years based on a minimal dataset. This will enable monitoring, evaluation and comparison of the respective activities in the emergency primary health care services. The aim of this study was to assess incidence of emergency contacts (potential life-threatening situations, red responses) to the emergency primary health care service.MethodsA representative sample of Norwegian emergency primary health care districts, "The Watchtowers" recorded all contacts and first action taken during the year of 2007. All the variables were continuously registered in a data program by the attending nurses and sent by email to the National Centre for Emergency Primary Health Care at a monthly basis.ResultsDuring 2007 the Watchtowers registered 85 288 contacts, of which 1 946 (2.3%) were defined as emergency contacts (red responses), corresponding to a rate of 9 per 1 000 inhabitants per year. 65% of the instances were initiated by patient, next of kin or health personnel by calling local emergency medical communication centres or meeting directly at the casualty clinics. In 48% of the red responses, the first action taken was a call-out of doctor and ambulance. On a national basis we can estimate approximately 42 500 red responses per year in the EPH in Norway.ConclusionThe emergency primary health care services constitute an important part of the emergency system in Norway. Patients call the LEMC or meet directly at casualty clinics with medical problems that initially are classified as a potentially life-threatening situation, a red response.
