Attribute Value
Methodology
  • Participants self-reported information on surveys using Audio Computer-Assisted Self-Interview software. To supplement survey responses about specific health outcomes, study staff extracted missing data from standard Ministry of Health antenatal, birth, neonatal, and postnatal registers; individual longitudinal antenatal and postnatal records; and through personal follow-up (e.g., miscarriage, stillbirth, gestational age at birth, birth weight, and maternal and infant death). Data cleaning checks (range and logic) were applied, and eligibility and critical outcomes data requiring further cleaning were completed by designated study staff to review and resolve discrepancies.
Description
  • We conducted a hybrid effectiveness-implementation trial at seven clinics in Blantyre District, Malawi, comparing outcomes for 1887 pregnant women randomly assigned to Group ANC or Individual ANC. The seven study clinics were selected in consultation with the Blantyre District health team to represent a diversity of clinics and communities served. The catchment areas and populations served by the clinics differ socioeconomically. Three clinics serve the urban population of Blantyre city, the rapidly-growing second largest city in Malawi. Two clinics serve the peri-urban communities adjacent to metropolitan Blantyre, and two clinics primarily serve a rural and predominately agricultural community. The clinics varied in volume and number of working midwives.

  • To be eligible to participate in this study, participants had to be pregnant, over the age of 14, have a gestational age of less than 24 weeks, and be capable of making an informed choice about participation. Those aged 15-17 assented with consent from a legal guardian. Those who did not meet all criteria were excluded. All pregnant women presenting for their first antenatal visit received the same standard individual intake visit that included a health assessment with the midwife, laboratory tests, and HIV testing.

  • After completing the intake visit, midwives directed clients to study team members so that eligibility could be assessed. Interested women then learned the information needed to give informed consent and sign a consent form. They then completed the baseline self-report survey using Audio Computer-Assisted Self-Interview software. The study statistician determined the randomization order list for each site before recruitment, and assignments were placed in order in sealed envelopes. After completing the baseline survey, the woman selected the next sealed envelope in that clinic’s box to reveal the type of ANC assignment, Group ANC or Individual ANC. Seven individual-level demographic and socioeconomic variables were treated as covariates in all analyses. Two clinic-level variables were also included as covariates, catchment area (rural, peri-urban, or urban) and midwife ANC workloads. Midwife ANC workloads were captured by a ratio of the average number of new ANC clients served each month divided by the number of midwives, with a higher ratio indicating a higher workload. The ratio was highest in two rural-serving clinics and substantially lower in peri-urban and urban communities.

Dataset Title: Malawi Group Antenatal Care Effectiveness Dataset

Data Creators: C.L. Patil

Dataset Contact: Crystal Patil [email protected]

Funding: This study was funded via Grant #R01NR018115, awarded to the University of Illinois Chicago from the National Institutes of Health, National Institute for Nursing Research
(NINR). The funder had no role in study design, data collection and analysis, decision to publish, or preparation of manuscripts.

Key Points:
- This dataset relates to the first aim of the study comparing outcomes for pregnant women randomly assigned to Group ANC or Individual ANC at seven clinics in Blantyre District, Malawi.

Research Overview:
We conducted a hybrid effectiveness-implementation trial with two aims. Details summarizing the study's conceptual basis, methods, and design are in a published protocol paper. This dataset was used to produce the results of the effectiveness aim with data collected between 5 July 2019 and 10 August 2023, comparing outcomes
for pregnant women randomly assigned to Group ANC or Individual ANC at seven clinics in Blantyre District, Malawi. The proposed sample size ensured a statistical power of > 99% for detecting effects on our clinical outcomes.

Methodology:
The data is a Microsoft Excel workbook (.xlsx) as formatted output form from the Statistical Analysis System (SAS) version 9.4.

Date Coverage: 5 July 2019 and 10 August 2023

Instrument and/or Software specifications: NA

Files contained here:
The EXCEL spreadsheet file `Malawi Group Antenatal Care Effectiveness Dataset` includes all variables used to assess effectiveness The variables included are described below:

The first part includes definitions of the individual-level and clinic-level covariates.

Individual-level covariates:

- Correct_ID: Participants' ID

- Assignment: The intervention indicator variable with Group ANC (intervention) and Individual ANC (control).

- Age: The participant's age was at the baseline visit.

- Age_Category: A 3-category ordinal variable: (1) `15-19` years (adolescents); (2) `20-29` years (young mothers); and (3) `30-35+` years (older mothers). Age `15-19` years is the reference category.

- Parity: A 2-category indicator is used: (1) `Primiparity` indicating a first pregnancy or (2) `Multiparity` indicating one or more previous pregnancies. `Primiparity` is the reference category.

- In a Relationship: Self-defined relationship status: (1) `Not in a relationship` (includes Separated or divorced, Single, and Widowed) or (2) `In a relationship` (married, living with a partner, or dating someone). `Not in a relationship` is the reference category.

- Education: A three-category ordinal variable: (1) `< Primary` (less than a primary education); (2) `Primary` (completed primary education); and (3) `SecondaryComplete` (more than a primary education). `< Primary` is the reference category.

- Food Insecurity: Participants were asked whether their household had ever run out of food or money to buy food in the last 12 months. For this dichotomous variable, `No never` (no food insecurity) is the reference category.

- Ownership Index: Participants were asked yes/no questions about having "electricity or a generator," "owning farm animals," and "agricultural land." The total number of yes responses produced the index as an ordinal variable (0-3), with 0 serving as the reference category.

- Income Quartile: Participants were asked to approximate the weekly income generated by the household. These values were converted to USD equivalents based on the year the survey was completed. Quartiles were produced and are treated as an ordinal variable: (1) `Q1` (Quartile 1, $0-$0.98); (2) `Q2` (Quartile 2, $0.98-$2.88); (3) `Q3` (Quartile 3, $2.88-$5.77); and (4) `Q4` (Quartile 4, >=$5.77). `Q1` is the reference category.

Clinic-level covariates:

- clinic_ID: ID of 7 clinics selected in the Blantyre district.

- Client-to-midwife ratio: Average number of new ACN clients per month divided by the number of midwives providing ANC. A higher ratio indicates a higher workload per midwife. Range, 7.4-29.0.

- Community catchment area: A 3-category ordinal indicator of the community clinics served: (1) `Rural` (n=2) have low population density and mainly agricultural economic activities; (2) `Peri-urban` (n=2) are near urban centers with a mix of rural and urban characteristics; and (3) `Urban` (n=3) are densely populated, with a more diverse economy. `Rural` is the reference category.

The second part includes outcome measures aligned with the theory of change model.
