Methodological issues in quantifying the magnitude of the tuberculosis problem in a prison population

SETTING: Correctional settings and remand prisons. OBJECTIVE: To critically discuss calculations for epidemiological indicators of the tuberculosis (TB) burden in prisons and to provide recommendations to improve study comparability. METHODS: A hypothetical data set illustrates issues in determining incidence and prevalence. The appropriate calculation of the incidence rate is presented and problems arising from cross-sectional surveys are clarifi ed. RESULTS: Cases recognized during the fi rst 3 months should be classifi ed as prevalent at entry and excluded from any incidence rate calculation. The numerator for the incidence rate includes persons detected as having developed TB during a specifi ed period of time subsequent to the initial 3 months. The denominator is persontime at risk from 3 months onward to the end point (TB or end of the observation period). Preferably, entry time, exit time and event time are known for each inmate to determine person-time at risk. Failing that, an approximation consists of the sum of monthly head counts, excluding prevalent cases and those persons no longer at risk from both the numerator and the denominator. CONCLUSIONS: The varying durations of inmate incarceration in prisons pose challenges for quantifying the magnitude of the TB problem in the inmate population. Recommendations are made to measure incidence and prevalence.

Emergency department admissions to a prison hospital: a retrospective cohort study from Switzerland

There are more than 10 million prison inmates throughout the world and this number is increasing continuously. Prisoners are a particularly vulnerable minority group that has special healthcare needs and demands on healthcare services and providers. The aim of this study was to give an overview of prisoners' healthcare problems leading to emergency department admission, in order to make recommendations to help to optimise treatment of this target group.

HIV infection, viral hepatitis and liver fibrosis among prison inmates in West Africa.

BACKGROUND Prisoners represent a vulnerable population for blood-borne and sexually transmitted infections which can potentially lead to liver fibrosis and ultimately cirrhosis. However, little is known about the prevalence of liver fibrosis and associated risk factors among inmates in sub-Saharan Africa. METHODS Screening of liver fibrosis was undertaken in a randomly selected sample of male inmates incarcerated in Lome, Togo and in Dakar, Senegal using transient elastography. A liver stiffness measurement ≥9.5 KPa was retained to define the presence of a severe liver fibrosis. All included inmates were also screened for HIV, Hepatitis B Virus (HBV) and Hepatitis C Virus (HCV) infection. Substances abuse including alcohol, tobacco and cannabis use were assessed during face-to-face interviews. Odds Ratio (OR) estimates were computed with their 95 % Confidence Interval (CI) to identify factors associated with severe liver fibrosis. RESULTS Overall, 680 inmates were included with a median age of 30 years [interquartile range: 24-35]. The prevalence of severe fibrosis was 3.1 % (4.9 % in Lome and 1.2 % in Dakar). Infections with HIV, HBV and HCV were identified in 2.6 %, 12.5 % and 0.5 % of inmates, respectively. Factors associated with a severe liver fibrosis were HIV infection (OR = 7.6; CI 1.8-32.1), HBV infection (OR = 4.8; CI 1.8-12.8), HCV infection (OR = 52.6; CI 4.1-673.8), use of traditional medicines (OR = 3.7; CI 1.4-10.1) and being incarcerated in Lome (OR = 3.3; CI 1.1-9.8) compared to Dakar. CONCLUSIONS HIV infection and viral hepatitis infections were identified as important and independent determinants of severe liver fibrosis. While access to active antiviral therapies against HIV and viral hepatitis expands in Africa, adapted strategies for the monitoring of liver disease need to be explored, especially in vulnerable populations such as inmates.

[Body-packer ; body-stuffer - a medical challenge]

Since the seventies, the practice of drug smuggling in the form of body packing has increased in the Western world. The goal of our study was to present an algorithm for the safe management of intracorporal drug transport based on clinical experience and current evidence. The retrospective study, conducted over the past four years in our hospital prison, analyzes and discusses the diagnostic and therapeutic concepts. Thirty-four patients hospitalized 37 times in a 48-month period were included. In 28 patients drug packages were identified. Only two patients suffered from serious complications. The study demonstrates that following a specifically designed management algorithm based on clinical experience and principles of evidence-based medicine can optimize risk management, improve quality assurance and patient safety.

[Working under pressure]

From medical view the main problems of investigation and convicts are in particular in the range of the drugs and alcohol illnesses to see transferable diseases (HIV, hepatitis B - C and tuberculosis) and psychological illnesses. These complex diseases require a close meshed and intensive support of each individual patient and represent actually the main problem during an arrest. The development of the health service could address the new requirements making possible cost-conscious acting in handling with resources in the health service. In the canton Berne 957197 inhabitants live on a total area of 5959 km2. The police and military management operates the regional and district prisons as well as the transportation service for prisoners in the canton Berne for prisoners. The canton Berne has altogether 327 places. Since May 1971 persons from the regional and district prison and the penal institutions needing hospitalisation can be accepted. In the University hospital Berne on a specially equipped guard station and be cared for their medical problems. The prisoners profit in such a way from the entire range of the university facilities.
