Here is a complete, ready-to-use Materials and Methods section for your journal article on hospital medico-legal case records (2021-2025):
Materials and Methods
1. Study Design
This was a retrospective descriptive study based on hospital-recorded medico-legal cases. Retrospective record review is the standard approach when analyzing routinely collected clinical-legal data over a defined historical period, as it allows systematic profiling of case characteristics without intervention or prospective follow-up.
2. Study Setting
The study was conducted at [Name of Hospital], a [secondary/tertiary] care hospital located in [City/Region]. The hospital's medico-legal unit (MLU) serves as the designated facility for receiving, examining, and documenting all medico-legal cases referred by law enforcement agencies, judicial authorities, and emergency services within the catchment area.
3. Study Period
Hospital medico-legal records spanning January 1, 2021 to December 31, 2025 (a five-year period) were reviewed. This timeframe was selected to capture recent trends and any temporal changes in the pattern of medico-legal presentations.
4. Study Population
Inclusion criteria:
- All medico-legal cases registered and managed at the hospital during the study period
- Cases with complete or retrievable records in the medico-legal register and case files
Exclusion criteria:
- Cases with missing core data (e.g., age, sex, nature of case, or medico-legal findings) where imputation was not possible
- Duplicate records for the same case encounter
- Cases where medico-legal documentation was initiated but the examination was not completed
5. Data Source and Collection
Data were extracted from the hospital's medico-legal case register (manual or electronic), individual medico-legal examination files/reports, and, where applicable, inpatient admission records and discharge summaries. A structured data extraction form (proforma) was designed prior to data collection and piloted on a sample of records to ensure clarity and consistency.
Variables collected included:
- Demographic data: age, sex, residential address/area
- Case characteristics: date and time of presentation, nature of medico-legal case (e.g., assault, road traffic accident, sexual offense, suspected poisoning, death brought in dead [BID])
- Clinical findings: nature of injuries, their type (abrasion, contusion, laceration, fracture, etc.), body region affected, severity (simple/grievous per applicable legal classification)
- Outcome data: admission/discharge, referral, death, case disposal
- Documentation data: referring authority (police, court, self/family)
6. Sampling
A total census (universal sampling) approach was used - all medico-legal cases registered during the study period that met inclusion criteria were included. No random sampling was applied, as the objective was to describe the entire population of cases over the defined timeframe.
7. Ethical Considerations
Ethical approval was obtained from the Institutional Review Board/Ethics Committee of [Institution Name] (Approval No: ____). Because the study involved retrospective review of de-identified case records and posed no direct risk to patients, a waiver of individual informed consent was granted in accordance with applicable institutional and national guidelines. Patient confidentiality was maintained throughout; no personally identifiable information appears in the published data. Permission to access hospital records was obtained from the hospital administration and/or the medical records department.
8. Data Management
Extracted data were entered into [Microsoft Excel / SPSS / EpiData / REDCap] by trained data collectors. Double-entry verification was performed on a random 10% sample of records to check for entry errors. Data were cleaned before analysis, with outliers and implausible values queried against original records.
9. Statistical Analysis
Data were analyzed using [SPSS version XX / Stata / R]. Descriptive statistics were used throughout:
- Categorical variables (sex, case type, injury type, referring authority, outcome) were summarized as frequencies and percentages, and presented in tables and bar charts.
- Continuous variables (age) were assessed for normality and summarized as mean ± standard deviation (SD) or median with interquartile range (IQR), as appropriate.
- Temporal trends (year-on-year case volume, seasonal distribution) were displayed using trend lines and frequency distributions.
- Chi-square tests or Fisher's exact test were used where appropriate to assess associations between categorical variables.
A p-value of < 0.05 was considered statistically significant.
10. Limitations
The main limitations of this study are inherent to retrospective record review: reliance on the completeness and accuracy of existing documentation, possible under-registration of cases (particularly those not referred by police), and inability to follow up outcomes beyond hospital discharge. These limitations are acknowledged and discussed in context.
Practical Tips Before Submission
| Step | Action |
|---|---|
| Ethics approval | Obtain and state the approval number in the manuscript |
| Journal selection | Target forensic medicine, legal medicine, or public health journals (e.g., Journal of Forensic and Legal Medicine, Medicine, Science and the Law, Egyptian Journal of Forensic Sciences) |
| STROBE checklist | Use the STROBE checklist for observational studies - most journals require it |
| Authorship | Confirm all authors meet ICMJE criteria (conception, data, drafting, approval) |
| Data availability | Some journals require a data availability statement even for hospital records |
This framework follows standard conventions for retrospective descriptive studies and aligns with published medico-legal record reviews from institutions in South Asia, the Middle East, and Africa. Customize the bracketed fields with your institution's specific details before submission.
