Community-based follow-up of participants of a mother-friendly clinical trial: A patient-centric methodology for pregnant women.

Repeated visits to clinical trial sites inflict hardships on study participants, especially pregnant women. A newer trend is community-based follow-up for measurements, dosage, or monitoring, through technology or physical visits. We conducted a methodological experiment of performing "community-based physical follow-up" of participants of a trial, receiving facility-based diagnosis and pathogen-specific antibiotics for asymptomatic bacteriuria, guided by an optical-sensor-based rapid point-of-care test. We were able to retain 95.8% participants in the study. Here we describe challenges faced and socio-economic and gender issues encountered in this approach in a low-resource Indian scenario, to guide researchers world-wide for designing mother-friendly clinical trials.

Effectiveness of antenatal screening of asymptomatic bacteriuria in reduction of prematurity and low birth weight: Evaluating a point-of-care rapid test in a pragmatic randomized controlled study.

BACKGROUND: Premature babies suffer higher mortality and life-long disabilities. Asymptomatic bacteriuria (ASB) is postulated to induce preterm labor. Routine antenatal screening for ASB using urine culture is not feasible in most developing countries due to long turn-around time, user-unfriendliness, and lack of resources. The current parallel-group superiority pragmatic randomized controlled trial evaluated the effect of screening and evidence-based treatment of ASB using an optical-sensor-based point-of-care rapid-test on the incidence of preterm birth and low birthweight (LBW). METHODS: 240 consenting asymptomatic pregnant women visiting an Indian tertiary public hospital for first antenatal check-up, irrespective of trimester/gravida, who had not consumed antibiotics in the preceding week, were enrolled from February-May 2017. Computer-generated concealed simple randomization allocation sequence was used to assign participants to intervention (120) and control arm (120). Usual hospital-care was provided in the control arm. In the intervention arm, urine samples were additionally screened for ASB using the rapid-test and the positive women were prescribed susceptible antibiotics. Blinded outcome assessors followed up with women post-delivery. The study was registered with the Clinical Trials Registry-India (CTRI/2016/09/007240). FINDINGS: 213 participants were analyzed (intervention: 103, control: 110). 21 women were found positive for ASB and prescribed pathogen-specific antibiotics. The incidence of preterm birth/LBW in intervention arm (n = 27) was lower than control arm (n = 45) by 14·7% (95% CI: 2·2-27·2); RR: 0.64, (95% CI: 0·43-0·95); p = 0·023, X2=5·13. INTERPRETATION: Rapid-test-guided treatment for ASB reduced the incidence of preterm birth/LBW in a pragmatic setting without any adverse event.
