INTRODUCTION

However, Zomba Mental Hospital, Malawi, is experiencing a lot of rehospitalization some of which take place in less than a year after discharge.

•To find out the factors that lead to rehospitalization of patients at the mental hospital in Malawi.
•To assist policy makers to utilize the findings to come up with measures to minimize relapses and hence improve community integration of patients discharged from the psychiatric hospital.

DIAGNOSIS (CASENOTE)
• 46 (61.3%) of the cases and 41 (57.7%) of the controls were diagnosed as schizophrenia.
• The next common condition was Mania/bipolar disorder. There were 14 (18.7%) cases with this diagnosis and 12 (16.9%) controls
• The third diagnosis was drug-induced psychosis. Eight of the cases (10.7%) and 14.1% of the controls were diagnosed as having this condition

• 66.7% 0f the cases and 25% of the controls had been violent (p value of 0.005).

MEDICATION COMPLIANCE
•53% of the cases and 83.1% of the controls were compliant with medication following discharge (p value of 0.005)

Multivariate Analysis (logistic regression)The factors significantly associated with
being a case vs. control were:• primary or no education• living in rural area• having a history of violence to others• Lack of insight• non compliant with medication after discharge• not receiving financial and practical support
from family• not getting help with medication

DISCUSSION• From the findings we conclude that the nature of the
illness is associated with rehospitalization due to:▫ having a history of violence to others▫ not believing that has a mental illness
• We did not find an association with marijuana misuse (but this was self-report)
• Those who are not rehospitalized are getting less support from the family:▫ receiving financial support from family▫ getting help with medication
• .

DISCUSSION• Several modifiable factors are associated with
rehospitalization of patients:
▫ not receiving practical support from family• not compliant with medication after discharge• residing in rural areas
• These could be improved by improving community outreach services particularly in rural areas.
• Home visiting to include psychoeducation, support with medication compliance, and rehabilitation

Limitations of the study
We depended on cases to give information which may not be reliable.
The study only looked at cases and controls from Zomba which may not be representative for Malawi

Recommendations for practice and future research
For future research involve other districts and health centers.
A prospective cohort study can also be done to recruit patients on discharge and follow them up.
