Treatment outcome of asthma after one year follow-up in health centres of several developing countries

SETTING

Seven selected out-patient clinics caring for asthma patients in Algeria, Guinea, Morocco, Syria, Turkey and Vietnam.

DESIGN

Evaluation of treatment outcomes after one year of follow-up of a cohort of asthma patients consecutively enrolled in a prospective study evaluating routine practice.

RESULTS

Among 310 asthma patients registered, the following outcomes were recorded after one year of follow-up: 95 (31%) successful, 61 (20%) under control, 35 (11%) failed, 116 (37%) defaulted and 3 (1%) transferred. Among the 167 (53.9%) patients still on treatment after one year there was a substantial increase in the proportion of patients classified as intermittent at the end of treatment (from 11% to 53%), with a decrease in all categories of persistent asthma (from 34% to 12% for mild, 45% to 28% for moderate and 10% to 8% for severe asthma).

CONCLUSIONS

While patients' quality of life can be improved if they follow regular treatment, the key challenge in providing care is to ensure that patients adhere to their treatment.

Implementation of asthma guidelines in health centres of several developing countries

SETTING

Nine selected out-patient clinics caring for asthma patients in Algeria, Guinea, Ivory Coast, Kenya, Mali, Morocco, Syria, Turkey and Vietnam.

DESIGN

Prospective enrolment of consecutive patients considered by the practitioner to have asthma with evaluation of adherence of the practitioner with recommended standard case management, including proportion of patients confirmed to have asthma, proportion in whom severity was correctly graded and proportion in whom treatment with inhaled corticosteroids corresponded to severity grade.

RESULTS

Of 499 consecutive patients, 456 (91%) were enrolled and evaluated. The diagnosis was confirmed in 263 (58%). Agreement between the practitioner and the guidelines in assigning grade of severity was moderate overall (kappa = 0.42). It was higher for assignment of grade using symptoms (K = 0.51), but poor for assignment of grade using peak expiratory flow (PEF) rate (kappa = 0.29), with practitioners tending to underestimate the severity. Agreement between the practitioners' assessment of severity and treatment with inhaled corticosteroids was poor (kappa = 0.18), with underutilisation of inhaled corticosteroids.

CONCLUSIONS

Practitioners caring for asthma patients in this study tended to underutilise the PEF rate in assessing their patients and underutilised treatment of patients with inhaled corticosteroids.
