Clinical Trial Summary

This randomized controlled trial will compare the incidence of vaginal infections in the post-partum period in women using sanitary napkins, with women using their current methods of managing lochia. 350 women will be recruited from a health center present in Badin, Sindh, and will be randomized into an intervention or control group. The intervention group will receive maternity napkins while the control group will continue to use their current method of lochia management. Symptoms of vaginal infection and patient comfort with the method of lochia management will be assessed by a questionnaire administered by a research assistant via bi-weekly visits. A self -administered low vaginal swab will also be obtained at each visit.

Description:

This is a randomized controlled trial using two parallel groups. District Thatta is a rural area that is situated two hours north of Karachi by drive. The Department of Community Health Sciences at the Aga Khan University (AKU), Karachi is working at District Thatta at established sites. In the proposed study, we will enroll 300 subjects in total randomized to either treatment or standard of care arm in a 1:1 ratio.

Thirty-six maternity napkins (two packets) will be provided to each participant at the time of recruitment and will be restocked at each follow-up visit. The control group will continue to use their current indigenous methods for managing postpartum lochia.

The research assistants will visit participants bi-weekly to administer questionnaires regarding symptoms of vaginal infection and comfort with use of method for management of lochia and restock the maternity napkins in the intervention group. Women who are unable to self-administer the questionnaire due to high illiteracy rates in the community, will be read out the form by the research assistant and their responses will be recorded. The research assistant will also provide the participant with equipment for a low vaginal swab at each bi-weekly visit with directions for administering. Once the participant has self-administered it, the research assistant will collect the swab and drop it at the clinical site. Alternatively, women will be invited to maternal and health center where the sample will be collected by a trained research assistant. If there is microorganism growth on a low vaginal swab, the participant will be informed and provided free treatment at the maternal and child health center. Any complications that arises during treatment including but not limited to sepsis and mortality will be documented. Any concomitant treatment that the participant wishes to receive will be recorded and there will be no restrictions placed on it.

The randomization method will use permuted blocks of variable size, randomly varying from 2 to 6 participants. Stratification factors in the randomization will be on the basis of type of delivery: vaginal delivery and Caesarian section (C-section) delivery since C-section delivery may be associated with a higher incidence of vaginal infection. The allocation will be secured in a plain white envelope. The nurse will provide maternity napkins to the participants in the intervention group and assign unique study identification (ID) numbers to each participant.

Participants will be randomized into an intervention and control group. Written and informed consent will be obtained from the participants prior to enrolment. The consent form has been translated to Sindhi for the purpose of this study. A research team member will be available close by to provide any clarification necessary. For participants who are unable to read, the consent from will be read out to them and their consent will be marked by a research team member. All information regarding the participants will be stored in a secured container and entered into an excel sheet which will be password protected with limited access to the research team only. The participant will be assigned a subject ID number to maintain the anonymity. In case a reproductive tract infection is detected, participants will be provided treatment free of cost by an available doctor at the maternal and child health center where the childbirth occurred according to culture and sensitivity. Serious adverse events are not expected because of the intervention. However, in case of a non-urgent adverse event, the participant will be provided a contact number at the time of recruitment which they can call to report the outcome and schedule an appointment at the maternal and child health center. In case of an emergency, the participant will be requested to visit the maternal and child health center and receive treatment. Treatment costs will be covered in both situations. For protocol deviation, a question has been included in the bi-weekly follow-up questionnaire where participants can report a deviation.

Single data entry with visual comparison will be performed to minimize error. Then, 10-15 forms will be randomly selected from the sample and the data on them will be compared to the data entered in the system. The information entered in the excel spreadsheet will be password protected. There will be limited access to the data by the research team only. The data will be de-identified once data collection is complete to maintain privacy of the participants. Case report forms (CRFs) and vaginal swab specimens will be transported from Thatta, Pakistan to the research laboratory at AKU in Karachi, Pakistan. These specimens will have their unique identifier, demonstrating the protocol name and number, patient ID number and date of sample collection. No personal information will be available on the vaginal specimen containers. The association between patient IDs and names will be stored in a database at the research office (data management unit) at the AKU. The primary investigator at AKU will have access to this secure database only. The research staff at AKU will only have access to de-identified CRFs and specimens.

Baseline demographics including name, age, height, weight, education, monthly income, and employment will be noted. Past medical history including comorbidities, parity, obstetric history, and previous postpartum complications will also be inquired. Finally, current medication and hygiene practices will also be noted. These variables will be recorded by the research team member during the examination. At the time of recruitment, details of the procedure will also be recorded using the hospital records including method used for cord clamping, antiseptic use etc.

All analysis will be conducted using SPSS software version 19. Baseline characteristics will be presented separately for both arms as frequency and percentage for categorical variables, mean and standard deviation for normal continuous variables and median and interquartile range for continuous variables with skewed distribution.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Presence of Culture Positive Vaginal Infection	Participants will perform a self-taken low vaginal swab (LVS) every 2 weeks (bi-weekly) for confirmation of vaginal infection. Self-taken LVS are a viable alternative to clinician-taken high vaginal swab (HVS) with comparable sensitivity for detecting infection. Growth of micro-organisms including: Gardnerella vaginalis, Mycoplasma hominis, Prevotella species, Mobiluncus species, Trichomonas vaginalis, Candida albicans, Candida krusei, Candida glabrata will constitute positive culture growth.	4.5 months
Secondary	Symptoms of Vaginal Infection	Itching, perceived foul smelling vaginal discharge, fever, and lower abdominal pain will be inquired during the follow up visit every 2 weeks (bi-weekly) by the research assistant using an adapted questionnaire. The questionnaire will be validated in our study population before administration. The questionnaires have been developed in English and will be translated to Sindhi, the native language.	4.5 months
Secondary	Patient Comfort based on Means of Lochia Management	Comfort of the patient will be inquired and recorded during the follow-up visit every 2 weeks (bi-weekly) using an adapted Likert scale, with 1 being not comfortable, and 5 being very comfortable. Comfort will be assessed based on three components including comfort, perception and behavior. The questionnaires have been developed in English and will be translated to Sindhi, the native language, and validated in the study population before administration to the control and intervention group.	4.5 months
