Presentation Transcript

  1. Utilization of Audio visual medium for conveying sputum collection instructions for tuberculosis diagnosis Presenter: FredORINA

  2. Introduction • Tuberculosis still remains a disease with high public health implication due to: • Mode of transmission- airborne • Emergence of MDR and XDR • Diagnosis a challenge • because of low suspicion index • quality of specimen produced even with highly sensitive new molecular platforms • Relay of collection instructions

  3. Objective • Assessment the effectiveness of audiovisual digital platform in conveying instructions for sputum collection to presumed tuberculosis patients

  4. Methodology • Development sputum collection Booth • Standardized instructions for: • Cough production technique promoting deep coughing • Emphasis on Time to be taken for collection • Volume required • Specimen handling procedure after collection.

  5. Study area Population (2009 census)  • Total 207,253

  6. Relay of sputum collection instructions • Approach 1 • (AVI) • Approach 2

  7. Patient recruitment and sample collection Randomized blockdesign Trained healthcare workers Audio visual Instructions Platform

  8. Specimen processing schematic

  9. RESULTS: Demographic characteristics • Data from 202 patients was analyzed • Mean age of 42 • Range 18-73 years

  10. Distribution of sputum by quality

  11. Distribution of sputum specimens by time of collection • No significant difference (p>0.05) between spot and morning samples • Accurate sputum collection instructions

  12. Primary outcomes POC diagnostics • GX better tool in diagnosis of TB than ZN microscopy as a POC tool • More patients were diagnosed with sputum from booth

  13. Pros and cons of AVI Pros • Privacy of participant • Ability of participant to review/playback the instructions • Availability of online solutions Cons • Some level of literacy to operate • Relied on grid power to fx

  14. Conclusions and recommendations • Audio visual instruction platforms can be used as an alternative to trained staff for relay of sputum collection instructions to presumptive tuberculosis patients • Quasi experimental studies on impact of the use of audio visual instructions on tuberculosis detection.
