Exploring the similarities and differences of burn registers globally: Results from a data dictionary comparison study

INTRODUCTION

Pooling and comparing data from the existing global network of burn registers represents a powerful, yet untapped, opportunity to improve burn prevention and care. There have been no studies investigating whether registers are sufficiently similar to allow data comparisons. It is also not known what differences exist that could bias analyses. Understanding this information is essential prior to any future data sharing. The aim of this project was to compare the variables collected in countrywide and intercountry burn registers to understand their similarities and differences.

METHODS

Register custodians were invited to participate and share their data dictionaries. Inclusion and exclusion criteria were compared to understand each register population. Descriptive statistics were calculated for the number of unique variables. Variables were classified into themes. Definition, method, timing of measurement, and response options were compared for a sample of register concepts.

RESULTS

13 burn registries participated in the study. Inclusion criteria varied between registers. Median number of variables per register was 94 (range 28 - 890), of which 24% (range 4.8 - 100%) were required to be collected. Six themes (patient information, admission details, injury, inpatient, outpatient, other) and 41 subthemes were identified. Register concepts of age and timing of injury show similarities in data collection. Intent, mechanism, inhalational injury, infection, and patient death show greater variation in measurement.

CONCLUSIONS

We found some commonalities between registers and some differences. Commonalities would assist in any future efforts to pool and compare data between registers. Differences between registers could introduce selection and measurement bias, which needs to be addressed in any strategy aiming to facilitate burn register data sharing. We recommend the development of common data elements used in an international minimum data set for burn injuries, including standard definitions and methods of measurement, as the next step in achieving burn register data sharing.

Suicide and self-harm by burns in Pakistan: a scoping review protocol

INTRODUCTION

Suicide is a global public health problem. Self-inflicted burns are one of the most severe methods of suicide, with high morbidity and mortality. Low-income and middle-income countries contribute 40% of all suicidal burns. Pakistan lacks comprehensive burns surveillance data, which prevents an understanding of the magnitude of the problem. This scoping review aims to understand the scope of the problem of suicide and self-harm burns in Pakistan and to identify knowledge gaps within the existing literature related to this specific phenomenon.

METHODS AND ANALYSIS

This scoping review will follow the methodological framework proposed by Arksey and O'Malley. We will search electronic databases (PubMed, Cochrane, Google Scholar and Pakmedinet), grey literature and a reference list of relevant articles to identify studies for inclusion. We will look for studies on self-inflicted burns as a method of suicide and self-harm in Pakistan, published from the beginning until December 2023, in the English language. Two independent reviewers will screen all abstracts and full-text studies for inclusion. The data will be collected on a data extraction form developed through an iterative process by the research team and it will be analysed using descriptive statistics.

ETHICS AND DISSEMINATION

Ethical exemption for this study has been obtained from the Institutional Review Board Committee of Aga Khan University Karachi, Pakistan. The findings of the study will be disseminated by conducting workshops for stakeholders, including psychiatrists, psychologists, counsellors, general and public health physicians and policymakers. The findings will be published in national and international peer-reviewed journals.

Development of an electronic burns register: Digitisation of routinely collected hospital data for global burns surveillance

INTRODUCTION

Burn registers provide important data that can track injury trends and evaluate services. Burn registers are concentrated in high-income countries, but most burn injuries occur in low- and middle-income countries where surveillance data are limited. Injury surveillance guidance recommends utilisation of existing routinely collected data where data quality is adequate, but there is a lack of guidance on how to achieve this. Our aim was to develop a rigorous and reproducible method to establish an electronic burn register from existing routinely collected data that can be implemented in low resource settings.

METHODS

Data quality of handwritten routinely collected records (register books) from a tertiary government hospital burn unit in Mysore, India was assessed prior to digitisation. Process mapping was conducted for burn patient presentations. Register and casualty records were compared to assess the case ascertainment rate. Register books from February 2016 to February 2022 were scanned and anonymised. Scans were quality checked and stored securely. An online data entry form was developed. All data underwent double verification.

RESULTS

Process mapping suggested data were reliable, and case ascertainment was 95%. 1930 presentations were recorded in the registers, representing 0.84% of hospital all-cause admissions. 388 pages were scanned with 4.4% requiring rescanning due to quality problems. Two-step verification estimated there to be errors remaining in 0.06% of fields following data entry.

CONCLUSION

We have described, using the example of a newly established electronic register in India, methods to assess the suitability and reliability of existing routinely collected data for surveillance purposes, to digitise handwritten data, and to quantify error during the digitisation process. The methods are likely to be of particular interest to burn units in countries with no active national burns register. We strongly recommend mobilisation of resources for digitisation of existing high quality routinely collected data as an important step towards developing burn surveillance systems in low resource settings.

Terminology and methods used to differentiate injury intent of hospital burn patients in South Asia: Results from a systematic scoping review

INTRODUCTION

A key component in the classification of all injury types is to differentiate whether the injury was deliberately inflicted and by whom, commonly known as "intent" in the surveillance literature. These data guide patient care and inform surveillance strategies. South Asia is believed to have the greatest number of intentional burn injuries, but national surveillance data is not disaggregated by injury intent. Scientific literature can be used for injury surveillance where national data collection does not exist. In order to synthesise research findings, it is essential to assess the potential impact of misclassification bias. We therefore conducted a systematic scoping review to understand terminology and methods used to differentiate injury intent of hospital burn patients in South Asia.

METHODS

We followed the methods in our registered protocol (https://doi.org/10.17605/OSF.IO/DCYNQ). Studies met defined population, concept, context, and study design criteria. The databases Embase, MEDLINE, CINAHL, PsycInfo, and PakMediNet were searched. Two reviewers independently screened results. Data were extracted in a standardised manner and verified. The rigour of the method used to differentiate injury intent was appraised.

RESULTS

1435 articles were screened. Of these, 89 met our inclusion criteria. Most articles were from India and Pakistan, and used an observational study design. There were 14 stem terms used in the articles. The most common was "cause". There were 40 classifier terms. The most common were "accident", "suicide", and "homicide". Few articles defined these terms. The method used to differentiate injury intent was only described explicitly in 17% of articles and the rigour of the methods used were low. Where methods of differentiation were described, they appear to be based on patient or family report rather than multidisciplinary assessment.

CONCLUSION

The heterogeneity in terms, lack of definitions, and limited investigation of injury intent means this variable is likely to be prone to misclassification bias. We strongly recommend that the global burn community unites to develop a common data element, including definitions and methods of assessment, for the concept of burn injury intent to enable more reliable data collection practices and interstudy comparisons.

Terminology and methods used to differentiate injury intent of hospital burn patients in South Asia: a systematic scoping review protocol

BACKGROUND

The greatest proportion of burn injuries globally occur in South Asia, where there are also high numbers of intentional burns. Burn injury prevention efforts are hampered by poor surveillance data on injury intent. There is a plethora of local routinely collected data in the research literature from South Asia that could be used for epidemiological purposes, but it is not known whether the definitions and methods of differentiation of injury intent are sufficiently homogenous to allow valid study comparisons.

METHODS

We will conduct a systematic scoping review to understand terminology and methods used to differentiate injury intent of hospital burn patients in South Asia. The objectives of the study are to: determine the breadth of terminology and common terms used for burn injury intent; to determine if definitions are comparable across studies where the same term is used; and to appraise the rigour of methods used to differentiate burn injury intent and suitability for comparison across studies. The databases Embase, MEDLINE, CINAHL, PsycINFO, and PakMediNet will be searched. Screening and data extraction will be completed independently by two reviewers. To be included, the article must be as follows: peer reviewed, primary research, study cutaneous burns, based on hospital patients from a country in South Asia, and use intent terminology or discuss a method of differentiation of injury intent. Results will be restricted to English language studies. No date restrictions will be applied. A plain language summary and terminology section are included for non-specialist readers.

DISCUSSION

Results will be used to inform stakeholder work to develop standardised terminology and methods for burn injury intent in South Asia. They will be published open access in peer-reviewed journals wherever possible.

Exploring the similarities and differences of variables collected by burn registers globally: protocol for a data dictionary review study

INTRODUCTION

Burn registers can provide high-quality clinical data that can be used for surveillance, research, planning service provision and clinical quality assessment. Many countrywide and intercountry burn registers now exist. The variables collected by burn registers are not standardised internationally. Few international burn register data comparisons are completed beyond basic morbidity and mortality statistics. Data comparisons across registers require analysis of homogenous variables. Little work has been done to understand whether burn registers have sufficiently similar variables to enable useful comparisons. The aim of this project is to compare the variables collected in countrywide and intercountry burn registers internationally to understand their similarities and differences.

METHODS AND ANALYSIS

Burn register custodians will be invited to participate in the study and to share their register data dictionaries. Study objectives are to compare patient inclusion and exclusion criteria of each participating burn register; determine which variables are collected by each register, and if variables are required or optional, identify common variable themes; and compare a sample of variables to understand how they are defined and measured. All variable names will be extracted from each register and common themes will be identified. Detailed information will be extracted for a sample of variables to give a deeper insight into similarities and differences between registers.

ETHICS AND DISSEMINATION

No patient data will be used in this project. Permission to use each register's data dictionary will be sought from respective register custodians. Results will be presented at international meetings and published in open access journals. These results will be of interest to register custodians and researchers wishing to explore international data comparisons, and countries wishing to establish their own burn register.

Establishing Self-Harm Registers: The Role of Process Mapping to Improve Quality of Surveillance Data Globally

Self-harm registers (SHRs) are an essential means of monitoring rates of self-harm and evaluating preventative interventions, but few SHRs exist in countries with the highest burden of suicides and self-harm. Current international guidance on establishing SHRs recommends data collection from emergency departments, but this does not adequately consider differences in the provision of emergency care globally. We aim to demonstrate that process mapping can be used prior to the implementation of an SHR to understand differing hospital systems. This information can be used to determine the method by which patients meeting the SHR inclusion criteria can be most reliably identified, and how to mitigate hospital processes that may introduce selection bias into these data. We illustrate this by sharing in detail the experiences from a government hospital and non-profit hospital in south India. We followed a five-phase process mapping approach developed for healthcare settings during 2019-2020. Emergency care provided in the government hospital was accessed through casualty department triage. The non-profit hospital had an emergency department. Both hospitals had open access outpatient departments. SHR inclusion criteria overlapped with conditions requiring Indian medicolegal registration. Medicolegal registers are the most likely single point to record patients meeting the SHR inclusion criteria from multiple emergency care areas in India (e.g., emergency department/casualty, outpatients, other hospital areas), but should be cross-checked against registers of presentations to the emergency department/casualty to capture less-sick patients and misclassified cases. Process mapping is an easily reproducible method that can be used prior to the implementation of an SHR to understand differing hospital systems. This information is pivotal to choosing which hospital record systems should be used for identifying patients and to proactively reduce bias in SHR data. The method is equally applicable in low-, middle- and high-income countries.

Evaluation of a framework for safe and appropriate prescribing of psychoactive medications in a UK prison

BACKGROUND

The widespread use of drugs in prisons leads to avoidable deaths, poorer health and a poor living environment. The contribution of psychoactive prescription drugs to this problem has received little attention in prison policy or at individual prescriber level.

AIMS

To determine the extent of unsafe and inappropriate prescribing of psychoactive medications in one UK prison using a newly developed medicines optimisation framework.

METHOD

A medicines optimisation framework was developed based on principles of good prescribing. It was initiated on the opening of a new prison-HMP Berwyn-in February 2017. During the study period, all prisoners at HMP Berwyn were transferred from other prisons. The safety and appropriateness of psychoactive medications were evaluated de novo on reception at HMP Berwyn and during follow up, using the medicines optimisation framework.

RESULTS

About 1941 sentenced men arrived at HMP Berwyn between February 2017 and November 2018. Nearly one-third (634, 33%) were on a prescribed psychoactive medication. Seventy-five percent of these (474/634) required a prescription change due to appropriateness or safety concerns. Nearly half (295, 46.5%) received changes at reception despite having already undergone medicines reconciliation at their previous prison. Forty-three percent (275/634) received changes at follow up, most commonly those who had no prior risks identified at reception.

CONCLUSIONS

Inappropriate and unsafe prescribing of psychoactive medications is occurring in prisons despite mandatory medication reviews. Ongoing monitoring is required to reduce the risk from these medications. A medicines optimisation framework such as this could be adopted across other prisons, worldwide, to help contribute to risk reduction from drug use in prisons. Appropriately modified, a similar framework might help reduce inappropriate and harmful prescribing in hospitals and in the community.

Linear regression analysis of Hospital Episode Statistics predicts a large increase in demand for elective hand surgery in England

INTRODUCTION

We integrated two factors, demographic population shifts and changes in prevalence of disease, to predict future trends in demand for hand surgery in England, to facilitate workforce planning.

METHODS

We analysed Hospital Episode Statistics data for Dupuytren's disease, carpal tunnel syndrome, cubital tunnel syndrome, and trigger finger from 1998 to 2011. Using linear regression, we estimated trends in both diagnosis and surgery until 2030. We integrated this regression with age specific population data from the Office for National Statistics in order to estimate how this will contribute to a change in workload over time.

RESULTS

There has been a significant increase in both absolute numbers of diagnoses and surgery for all four conditions. Combined with future population data, we calculate that the total operative burden for these four conditions will increase from 87,582 in 2011 to 170,166 (95% confidence interval 144,517-195,353) in 2030.

DISCUSSION

The prevalence of these diseases in the ageing population, and increasing prevalence of predisposing factors such as obesity and diabetes, may account for the predicted increase in workload. The most cost effective treatments must be sought, which requires high quality clinical trials. Our methodology can be applied to other sub-specialties to help anticipate the need for future service provision.
