The Changing Pattern of Hospital Admission to Medical Wards: Burden of non-communicable diseases at a hospital in a developing country

OBJECTIVES

This study aimed to determine the pattern of hospital admissions and patient outcomes in medical wards at Atbara Teaching Hospital in River Nile State, Sudan.

METHODS

This retrospective cross-sectional study was conducted from August 2013 to July 2014 and included all patients admitted to medical wards at the Atbara Teaching Hospital during the study period. Morbidity and mortality data was obtained from medical records. Diseases were categorised using the World Health Organization's International Classification of Diseases (ICD) coding system.

RESULTS

A total of 2,614 patient records were analysed. The age group with the highest admissions was the 56-65-year-old age group (19.4%) and the majority of patients were admitted for one week or less (86.4%). Non-communicable diseases constituted 71.8% of all cases. According to ICD classifications, patients were admitted most frequently due to infectious or parasitic diseases (19.7%), followed by diseases of the circulatory (16.4%), digestive (16.4%) and genito-urinary (13.8%) systems. The most common diseases were cardiovascular disease (16.4%), malaria (11.3%), gastritis/peptic ulcer disease (9.8%), urinary tract infections (7.2%) and diabetes mellitus (6.9%). The mortality rate was 4.7%.

CONCLUSION

The burden of non-communicable diseases was found to exceed that of communicable diseases among patients admitted to medical wards at the Atbara Teaching Hospital.

Trade liberalization, social policies and health: an empirical case study

BACKGROUND

This study investigates the health impacts of a major liberalization episode in the textile and clothing (T&C) sector. This episode triggered substantial shifts in employment across a wide range of countries. It is the first study to empirically link trade liberalization to health via changes in employment and offers some of the first empirical insights on how trade liberalization interacts with social policies to influence health.

METHODS

Data from 32 T&C reliant countries were analysed in reference to the pre- and post-liberalization periods of 2000-2004 and 2005-2009. Fuzzy-set qualitative comparative analysis (fsQCA) was used to examine the association between countries' a) level of development b) labour market and welfare state protections c) T&C employment changes and d) changes in adult female and infant mortality rates. Process tracing was used to further investigate these associations through twelve in-depth country studies.

RESULTS

Results from the fsQCA relate changes in employment after the phase-out to both changing adult female and infant mortality rates. Findings from the in-depth country studies suggest that the worsening of adult female mortality rates is related to workers' lack of social protection, both in the context of T&C employment growth and loss.

CONCLUSIONS

Overall, it is found that social protection is often inaccessible to the type of workers who may be the most vulnerable to processes of liberalization and that many workers are particularly vulnerable due to the structure of social protection policies. Social policies are therefore found to both moderate pathways to health and influence the type of health-related pathways resulting from trade liberalizing policies.

An electronic register for vital registration in a rural village with no electricity in Malawi

SETTING

Chalasa village, Traditional Authority Mtema, Lilongwe District, Malawi.

OBJECTIVES

To report on the deployment of an electronic register in a rural village with no electricity. Specific objectives were to document 1) challenges in setting up the electronic village register (EVR); 2) demographics of village residents, along with births and deaths over three quarters; and 3) the costs of setting up the system.

DESIGN

A descriptive study.

RESULTS

The main challenges were slow adoption of the EVR by the village headman, lack of health passports for village residents, double counting of some residents and difficult connectivity. These challenges were overcome. In terms of data, of 790 village residents, 379 (48%) were male, 417 (53%) were aged <15 years and 29 (3.6%) ⩾65 years. From April to December 2013, there were 18 births and 5 deaths. The cost of the EVR, including maintenance costs for 12 months, was US$6210.

CONCLUSION

An EVR was successfully deployed in Chalasa village, rural Malawi, and data on the resident village population, along with quarterly births and deaths, are now available. This is the first step towards a village-level civil registration system in rural Africa.

Medical causes of admissions to hospital among adults in Africa: a systematic review

BACKGROUND

Despite the publication of several studies on the subject, there is significant uncertainty regarding the burden of disease among adults in sub-Saharan Africa (sSA).

OBJECTIVES

To describe the breadth of available data regarding causes of admission to hospital, to systematically analyze the methodological quality of these studies, and to provide recommendations for future research.

DESIGN

We performed a systematic online and hand-based search for articles describing patterns of medical illnesses in patients admitted to hospitals in sSA between 1950 and 2010. Diseases were grouped into bodily systems using International Classification of Disease (ICD) guidelines. We compared the proportions of admissions and deaths by diagnostic category using χ2.

RESULTS

Thirty articles, describing 86,307 admissions and 9,695 deaths, met the inclusion criteria. The leading causes of admission were infectious and parasitic diseases (19.8%, 95% confidence interval [CI] 19.6-20.1), respiratory (16.2%, 95% CI 16.0-16.5) and circulatory (11.3%, 95% CI 11.1-11.5) illnesses. The leading causes of death were infectious and parasitic (17.1%, 95% CI 16.4-17.9), circulatory (16%, 95% CI 15.3-16.8) and digestive (16.2%, 95% CI 15.4-16.9). Circulatory diseases increased from 3.9% of all admissions in 1950-59 to 19.9% in 2000-2010 (RR 5.1, 95% CI 4.5-5.8, test for trend p<0.00005). The most prevalent methodological deficiencies, present in two-thirds of studies, were failures to use standardized case definitions and ICD guidelines for classifying illnesses.

CONCLUSIONS

Cardiovascular and infectious diseases are currently the leading causes of admissions and in-hospital deaths in sSA. Methodological deficiencies have limited the usefulness of previous studies in defining national patterns of disease in adults. As African countries pass through demographic and health transition, they need to significantly invest in clinical research capacity to provide an accurate description of the disease burden among adults for public health policy.
