ABSTRACT
Aims: To explore the pattern of unmet medicine information needs of hypertensive patients on long term therapy and their attitude to use of SMS (mobile phone short message service) for medicine information exchange with hospital pharmacists. Sample: 117 hypertensive patients on long term therapy who had been accessing care for at least one year. Study Design: An exploratory medicine information exchange programme followed by a cross-sectional survey. Place and Duration of Study: Outpatient Clinic of Department of Cardiology at Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, Nigeria between October, 2010and May, 2011. Methods: Patients were prompted with SMS twice weekly for 5-8 months for use of their medication with advice to send their medicine information needs to the hospital pharmacist. Received messages were subjected to content analysis to identify their themes. A semi-structured questionnaire was used to explore patient attitude to the use of SMS. The 17-item questionnaire was designed on a 5-point Likert scale for responses with weights of 0-4. Data obtained were analysed using both descriptive and inferential statistics. These include frequencies and mean of weighted averages (MWA); tests of relationships, associations and of differences in means. Results: A total of 63 SMS texts were received from the respondents and 44% of the messages expressed medicine information needs. Majority of the enquiries were related to indications and adverse effects. The patients’ attitude to the use of SMS for medicine information exchange with pharmacists was generally positive (MWA=3.13) with no significant demographic effects. Some (46%) of the patients called for institutionalisation of the medicine information exchange programme. Conclusion: The unmet medicine information needs of chronic hypertensive patients in the study were related mainly to indications and side effects of prescribed and nonprescribed medications and the patients clamoured for use of SMS in redressing the anomaly.
ABSTRACT
Formulae for predicting functional capacity during 6-minue walk are lacking and the accuracy of the existing formulae has been challenged in deferent populations. The purpose of this study was to develop an equation that would be useful in predicting functional capacity in form of maximum oxygen consumption) (V0 ) in Chronic Heart Failure Patients (CHF) during exercise. Sixty-five subjects were recruited for the study. The procedure required the subjects to walk on a self paced speed on a 20 meter marked level ground for 6 minutes. The distance covered in 6 minutes was measured and the speed calculated. The result showed that the distance covered was highly correlated with the VO2 (0.65; p 0.01). The regression analysis revealed that a linear equation model developed was a good predictor ofV0 for the group. The study concluded that in situation where sophisticated equipments are lacking; this equation might be useful during exercise supervision for patients withCHF. [VO2 (ml kg-1 min-1)
