School of Public Health / Management of multidrug-resistant tuberculosis (MDR-TB) is more expensive,
lengthy and is associated with less favourable outcomes and more adverse
reactions than management of susceptible tuberculosis. The aim of this study was
to review the management and treatment outcomes of registered MDR-TB patients
hospitalized at Sizwe hospital during a five-year period.
A cross-sectional study with both descriptive and analytic features was done on
237 MDR-TB patients hospitalized from the beginning of June 1998 to the end of
May 2003. Data were analysed using SPSS version 12 Software. Main outcome
measures were interim treatment outcomes at the end of hospitalization period.
These outcomes comprised culture conversion rates, time to culture conversion,
transfer out, interruption, and death rates. Multiple logistic regression analysis was
performed to determine risk factors for poor treatment outcomes. These poor
outcomes were defined as treatment interruption, failure and mortality rates.
The burden of institutional care for MDR-TB patients in this setting was found to
involve high numbers of MDR-TB patients for whom the allocated hospital beds
were insufficient. Patients with primary MDR-TB, who had no history of nonadherence
to treatment, were paradoxically more likely to be hospitalized shortly
after diagnosis. Acquired MDR-TB patients were mostly managed as outpatients
immediately after diagnosis only to be hospitalized later due to persistent nonadherence
or disease severity. Overall, acquired MDR-TB patients were
hospitalized in larger numbers than those with primary disease. This reflects the
higher prevalence of acquired MDR-TB compared to primary MDR-TB.

Abstract
Culture turnaround time was on average 19 days. The overall culture conversion
rate of the hospitalized patients was low at 41.9 percent. This low culture
conversion rate resulted in protracted hospitalization periods and high interim
mortality rates. The mean duration of hospitalization, 3.52 months, correlated
favourably with the time interval to the first culture conversion of 2.96 months.
Hospitalization did not guarantee the expected adherence to treatment. Surgical
interventions were done belatedly with resultant high mortality outcomes.
The main reasons given by patients for refusing hospital treatment were visiting
traditional healers, solving socioeconomic problems and attending to family
matters. A large percentage of hospitalized patients were co-infected with HIV.
HIV care and support was incomplete as antiretroviral drugs were not available at
the hospital. Among the main findings of the study was the powerful influence
HIV status had on poor hospitalization outcomes.
Recommendations arising from the study include the need to provide ARVs at the
Sizwe hospital. Admission and discharge guidelines aimed at ensuring adequate
beds are reserved for deserving patients should be formulated. Continuing
education for service providers must be encouraged and rewarded. Infection
control procedures at both community and health institution level ought to be
vigorously promoted. Patients known to be hopelessly non-adherent should at least
be partially hospitalized in the interest of public health.
