Acute respiratory infections in children: a community-based study comparing a primary health center and a pediatric unit, Republic of Guinea

A computer-based medical record system and personal digital assistants to assess and follow patients with respiratory tract infections visiting a rural Kenyan health centre

Background

Clinical research can be facilitated by the use of informatics tools. We used an existing electronic medical record (EMR) system and personal data assistants (PDAs) to assess the characteristics and outcomes of patients with acute respiratory illnesses (ARIs) visiting a Kenyan rural health center.

Methods

We modified the existing EMR to include details on patients with ARIs. The EMR database was then used to identify patients with ARIs who were prospectively followed up by a research assistant who rode a bicycle to patients' homes and entered data into a PDA.

Results

A total of 2986 clinic visits for 2009 adult patients with respiratory infections were registered in the database between August 2002 and January 2005; 433 patients were selected for outcome assessments. These patients were followed up in the villages and assessed at 7 and 30 days later. Complete follow-up data were obtained on 381 patients (88%) and merged with data from the enrollment visit's electronic medical records and subsequent health center visits to assess duration of illness and complications. Symptoms improved at 7 and 30 days, but a substantial minority of patients had persistent symptoms. Eleven percent of patients sought additional care for their respiratory infection.

Conclusion

EMRs and PDA are useful tools for performing prospective clinical research in resource constrained developing countries.

Risk factors for severe pneumonia in children in Basrah

A case-control study was undertaken in Basrah Maternity and Children Hospital, Iraq. We studied 148 children who were admitted to hospital with severe pneumonia according to the World Health Organization (WHO) criteria and the controls were 250 children attending the out-patient department for non-severe respiratory infections. Significant risk factors were younger age (2-6 months), low parental education, smoking at home, prematurity, weaning from breast milk at < 6 months, a negative history of diphtheria, pertussis and tetanus vaccination, anaemia and malnutrition.

Potential implications of the integrated management of childhood illness (IMCI) for hospital referral and pharmaceutical usage in western Uganda

The integrated management of childhood illness approach (IMCI) is currently being implemented by a number of countries worldwide. This is the second report from a study in western Uganda comparing the assessment and classification of disease by medical assistants using the IMCI algorithm with that of hospital-based general medical officers, who used their clinical judgement to assess and provide treatment. Treatment prescribed by the hospital medical officers was compared to that indicated by IMCI disease classifications. The study population comprised 1226 children aged 2-59 months. Medical assistants had some difficulty in completing the IMCI assessment, leading to incorrect classification of findings in 138 of 1086 completed forms (13%). If their classifications had been used to decide on hospital referral, 37 children who met IMCI criteria for referral would have been sent home. Consultations took on average 7.2 min, longer than usual for several African countries. Use of the IMCI guidelines would have referred 16.2% of children to hospital, compared with 22% referred by the medical officers. Use of IMCI could have reduced the cost of medication to US$0.17 per child compared to the treatment cost of US$0.82 as prescribed by medical officers. Medical officers prescribed both a greater number and a greater variety of drugs than indicated by the IMCI algorithm. Compared to the present management of sick children by medical officers at Kabarole district hospital, using the IMCI algorithm would bring major changes in pharmaceutical use and referral practices. However, there is concern about the difficulty medical assistants had in using it, and the potential for longer consultation times.
