Self care groups and ulcer prevention in Okegbala, Nigeria.

OBJECTIVE: To assess the impact of the three self-care Groups on ulcer prevalence and readmission rates in Okegbala hospital. DESIGN: A retrospective, descriptive study. The evaluation combined four data collection methods namely (i) records survey, (ii) semi-structured interviews of individual members of self-care groups, (iii) group discussions and (iv) key informant interviews. RESULTS: Record surveys show that the ulcer prevalence has decreased by almost 75% since the adoption of the self-care group; admissions to hospital for ulcer care have reduced, and the mean interval between admissions has increased by 7 months. Semi structured interviews and group discussions show that all members have a greater sense of control of their ulcers and general health; and that self-care groups have a potential of catalysing community solidarity and development. CONCLUSIONS: This small study shows that self-care groups are valuable for reducing ulcers and giving members a greater sense of control of their ulcers and general health resulting in fewer hospital admissions. We recommend a multi-centre, controlled, prospective study incorporating different settings (e.g. urban, rural, near hospitals, within field leprosy programmes) to test these findings. Such a study has the potential of influencing policy and health-service reorientation of ulcer care in future.

Monitoring impairment in leprosy: choosing the appropriate tool.

OBJECTIVE: To assess to what extent the Maximum WHO Impairment Grade, the EHF Score and Impairment Summary Form (ISF) reflect changes in impairment, both in number(s) and severity. DESIGN: The impairment data at registration and at release from treatment of 444 persons affected by leprosy registered for MDT from 1994-2003 in Federal Capital Territory, Nigeria were analysed using three monitoring tools. RESULTS: Of the 444 patients, 92 people had a change (10 deteriorated, 70 improved while 12 had improvement in some parts of their body and deterioration in other parts) in their impairment between Registration and Release from Treatment. Of the 10 people whose impairment status deteriorated, the WHO Grade missed 7 and the EHF score missed 4. The ISF missed none. Of the 70 whose impairment status improved, the WHO grade missed 27; the EHF score missed 20 and the ISF missed 9. The WHO Grade had a sensitivity of 50%, the EHF Score 61% and the ISF 90%. Negative predictive values were 88%, 91% and 98% respectively. CONCLUSIONS: The Maximum WHO Impairment Grade use should be limited to an indicator of late case detection. The EHF score is better used at programme level than individual patient level. The ISF is a sensitive tool for monitoring impairments at patient level to aid clinical decision making.
