Clinical features and settings |
Presenting signs and symptoms: History of fever in the previous 24 h or axillary temperature 37.5 °C or over; no evidence of concomitant febrile illness; no danger signs or evidence of severe malaria Previous treatment for malaria: No exclusion criteria based on antimalarial use; data collected on prior antimalarial use but not presented for the study sample Clinical setting: Regional referral hospital outpatient department Country: Uganda Malaria endemicity: Hyperendemic Malaria endemic species: Mainly P. falciparum |
|
Participants |
Sample size: 357 Age: Inclusion criteria over the age of six months; 46% were under the age of five; median age 11 years (range 1 to 28 years) Sex: Both males and females eligible; 60% were female and 40% male Co‐morbidities and pregnancy: People with evidence of concomitant febrile illness were excluded from the study Parasite density of microscopy positive cases: Not presented |
|
Study design | Enrollment was consecutive and prospective. One RDT was evaluated. | |
Target condition and reference standard(s) |
Target condition: Malaria parasitaemia Reference standard: Microscopy thick and thin blood smears Person(s) performing microscopy: Hospital microscopists Microscopy setting: Hospital laboratory Number of high power fields examined before declaring negative: 100 Number of observer or repeats: Two in most cases. A third microscopist read a random 10% of slides for quality control. Resolution of discrepancies between observers: A third external microscopist, unaware of the first two results, resolved any discordant results |
|
Index and comparator tests |
Commerical name of RDTs: ICT Malaria‐Pf (ICT Diagnostics, Brookvale, NSW, Australia) Parasite(s) designed to detect:P. falciparum Designated Type: Type 1 Batch numbers: Not stated Transport and storage conditions: Storage temperature ranged from 22 °C to 29 °C, and a single spike temperature of 38 °C was recorded during transportation Person(s) performing RDT: Two independent readings by trained staff RDT setting: Hospital laboratory |

Table of Methodological Quality | ||
Item | Authors' judgement | Description |
Representative spectrum? All tests | Yes | Participants were a consecutive series of people with fever attending outpatient clinics |
Acceptable reference standard? All tests | Yes | Two microscopists working in a central laboratory viewed at least 100 high power fields before declaring a slide negative |
Partial verification avoided? All tests | Yes | All participants who received the index test also received the reference test |
Differential verification avoided? All tests | Yes | The same reference test was used regardless of the index test results |
Incorporation avoided? All tests | Yes | The index test does not form part of the reference standard |
Reference standard results blinded? All tests | Unclear | Blinding not described |
Index test results blinded? All tests | Unclear | Blinding not described |
Uninterpretable results reported? All tests | Yes | 7 enrolled participants were excluded due to uninterpretable blood smears |
Withdrawals explained? All tests | Yes | 7 enrolled participants were excluded due to uninterpretable blood smears; otherwise there were no withdrawals |
