This project is using the TX_PVLS indicator for our proof of concept.
This indicator represents the percentage of ART patients with a suppressed viral load (VL) result (<1000 copies/ml) documented in the medical or laboratory records/laboratory information systems (LIS) within the past 12 months
Numerator
Number of adult and pediatric patients on ART with suppressed viral load results (<1,000 copies/ml) documented in the medical records and /or supporting laboratory results within the past 12 months.
We will consider patients with result from CIEL:856 with a threshold of < 1000 copies / mL as the standard for viral load suppression and in case the patient does not have a CIEL:856 result, we will consider results CIEL:
1306
1305where the value is (BEYOND DETECTABLE LIMIT)
CIEL:1306
Denominator
Number of adult and pediatric ART patients with a viral load result documented in the patient medical record and/or laboratory records in the past 12 month
We will consider patients with a relevant CIEL:1305 result but only if the patient does not have a CIEL:856 result
Concepts to consider
CIEL:856 (for quantitative values ) Fully Specified Name :HIV VIRAL LOAD Mappings: Same as SNOMED CT 315124004
CIEL:1305 (for qualitative values , in case the patient
doesnt
doesn't have a quantitative value). Fully Specified Name: HIV VIRAL LOAD, QUALITATIVE
Mappings: Same as SNOMED MVP 13051000105000, Narrower-than SNOMED 315124004
