Tracing Data Journeys Through Medical Case Reports: Conceptualizing Case Reports Not as “Anecdotes” but Productive Epistemic Constructs, or Why Zebras Can Be Useful

Medical case reports provide an important example of data journeying: they are used to collect data and make them available for re-use to others in the field including clinicians, biomedical researchers, and health policymakers. In this paper, I explore how data journey in case reports, with particular focus on the earliest stages of the process, namely from creation and publication of case reports to the initial re-uses of them and data within them. I investigate key themes relating to case reporting and re-use, including factors which seem to smooth the path along which the data captured by a case report journey via broader citation patterns and detailed qualitative analysis of highly re-used case reports. This analysis reveals some of the key factors associated with the case reports whose data have greater amounts of journeying including publication in a general medical journal; that the data have broader implications and evidential value for topical or even urgent issues for instance in public health; and use in the case report of multiple research methods or concepts from diverse subfields. These findings along with standardization of case reporting are shown to have epistemological implications, particularly for how we understand the journeying of data.

Hospitalizations for communicable diseases in a developing country: prevalence and trends-Monastir, Tunisia, 2002-2013

BACKGROUND

In spite of the epidemiological transition, communicable diseases remain a public health problem and represent a significant cause of morbidity and mortality worldwide, especially in developing countries. This study aimed to determine the crude and standardized prevalence rates of hospitalizations for communicable disease (HCD) and to assess trends in HCD by age and sex at a university hospital in Tunisia over a period of 12 years (2002-2013).

METHODS

All cases of HCD from 2002 to 2013 in the university hospital departments were included. Data collected from the regional register of hospital morbidity were used. The discharge diagnoses were coded according to the International Classification of Diseases, 10th revision (ICD-10).

RESULTS

HCD represented 17.45% of all hospitalizations during the study period (34 289/196 488; 95% confidence interval 17.28-17.62%). The median age at the time of admission was 31 years (interquartile range (IQR) 15-52 years). The median hospital length of stay (LOS) was 5days (IQR 3-9 days). The crude prevalence rate (CPR) was 5.41 per 1000 inhabitants. The CPR was highest among patients aged ≥65 years. The four communicable disease categories that represented 70% of all HCD were abdominal infection, skin infection, genitourinary infection, and lower respiratory tract infection. The majority of HCD decreased over time; however, there was a significant increase in HIV diseases, tuberculosis, and viral hepatitis.

CONCLUSION

This study provides evidence of the epidemiological transition, showing a decline in communicable diseases, which needs to be sustained and improved.
