Evaluation of Maternal and Fetal Outcomes, Clinical Management, and Guidelines Adherence in Pregnant Women with Gestational Hypertension and Pre-Eclampsia: An Ambispective Study

ABSTRACT

Background: Hypertensive disorders of pregnancy (HDP) - particularly gestational hypertension (GH) and pre-eclampsia (PE) - are among the leading causes of maternal and perinatal morbidity and mortality globally. In India, HDP affects 10-20% of all pregnancies, with pre-eclampsia incidence reported at 8-10% by the Indian Council of Medical Research (ICMR). Despite the availability of evidence-based guidelines from ACOG, NICE, ISSHP, and FOGSI, real-world adherence to these guidelines and their impact on outcomes remains incompletely characterised, particularly in tertiary care settings in India.
Objective: To evaluate maternal and fetal outcomes in women with GH and PE, assess the clinical management practices adopted, and determine the degree of adherence to standard clinical guidelines.
Methods: An ambispective observational study (combining retrospective review of past records and prospective follow-up of newly diagnosed cases) will be conducted at [Name of Institution]. Pregnant women diagnosed with GH or PE at or beyond 20 weeks of gestation will be enrolled. Data will be collected on antihypertensive therapy, magnesium sulfate use, mode of delivery, timing of delivery, investigations performed, and maternal and fetal outcomes. Guideline adherence will be scored against ISSHP 2021 / FOGSI recommendations.
Expected Outcomes: Identification of gaps in guideline adherence, predictors of adverse maternal and fetal outcomes, and recommendations for quality improvement.
Keywords: Gestational hypertension, pre-eclampsia, hypertensive disorders of pregnancy, maternal outcomes, fetal outcomes, guideline adherence, ambispective study, India.

1. INTRODUCTION

1.1 Background and Rationale

Hypertension in pregnancy is the second most common direct cause of maternal mortality worldwide, according to the World Health Organization (WHO 2014). Each year, an estimated 76,000 pregnant women die from pre-eclampsia and related hypertensive disorders - approximately 200 deaths per day.¹ In low- and middle-income countries (LMICs) including India, the burden is disproportionately higher. A retrospective study from a tertiary care centre in India spanning 2000-2009 identified HDP as the third major cause of maternal deaths.² A study by the Federation of Obstetric and Gynaecological Societies of India (FOGSI) reported that 51.10% of women who died did so in the peripartum or immediate postpartum period attributable to HDP and obstetric haemorrhage.³
Hypertensive disorders of pregnancy comprise four distinct clinical entities: (1) chronic hypertension, (2) gestational hypertension (GH), (3) pre-eclampsia (PE) / eclampsia, and (4) chronic hypertension with superimposed pre-eclampsia. The ACOG defines:
  • Gestational hypertension as new-onset hypertension (BP ≥140/90 mmHg) after 20 weeks of gestation, without proteinuria or signs of end-organ damage.
  • Pre-eclampsia as hypertension accompanied by proteinuria or other signs or symptoms of end-organ involvement, arising after 20 weeks of gestation.
  • Pre-eclampsia with severe features when systolic BP ≥160 mmHg, or diastolic BP ≥110 mmHg, or evidence of end-organ damage (renal, hepatic, neurological, haematological) is present.
  • HELLP syndrome as a specific form of PE with severe features characterised by haemolysis, elevated liver enzymes, and low platelet count.⁴
Approximately 25% of women initially diagnosed with GH will progress to PE, particularly those diagnosed before 34 weeks of gestation.⁵ The pathophysiology of PE centres on placental ischaemia, endothelial dysfunction, intravascular inflammation, and an imbalance between proangiogenic factors (VEGF) and antiangiogenic factors (sFlt-1), leading to multisystem end-organ involvement including neurological, renal, hepatic, and haematological complications.⁴
Cerebral haemorrhage and pulmonary oedema are the leading causes of death in women with eclampsia or PE with severe features. Fetal complications include intrauterine growth restriction (IUGR), preterm birth, placental abruption, and perinatal death. The CHIPS (Control of Hypertension in Pregnancy Study) trial demonstrated that tight BP control (diastolic BP target 85 mmHg) significantly reduced maternal complications, including severe hypertension and thrombocytopenia, without increasing perinatal risks.⁶
Despite clear guidelines from ACOG (2020, reaffirmed 2023), NICE (2019, updated 2023), ISSHP (2021), and FOGSI, real-world practice in India shows variability in recognition, investigation, antihypertensive choice, use of magnesium sulfate for seizure prophylaxis, timing of delivery, and postpartum follow-up. There is a paucity of data specifically evaluating guideline adherence and its relationship to outcomes in Indian tertiary care hospitals. This gap justifies the present study.

1.2 Study Design Justification (Ambispective Design)

An ambispective study combines the efficiency of retrospective data (using existing medical records for cases already managed) with the rigour of prospective data collection (following newly diagnosed patients in real time with standardised data capture). This design is particularly suited for this research because:
  • It allows a larger sample size within a feasible time frame.
  • Retrospective data provide information on outcomes already occurred, enabling immediate analysis.
  • Prospective data collection allows standardised, complete documentation of clinical variables including guideline adherence, which is difficult to extract reliably from retrospective records alone.
  • The combined approach offers a longer effective observation window and reduces selection bias inherent to purely prospective designs.

2. AIM AND OBJECTIVES

2.1 Primary Aim

To evaluate maternal and fetal outcomes in pregnant women diagnosed with gestational hypertension and pre-eclampsia, and to assess adherence to standard clinical guidelines in their management.

2.2 Specific Objectives

  1. To determine the prevalence and distribution of HDP subtypes (GH, PE without severe features, PE with severe features, eclampsia, HELLP syndrome) among the study population.
  2. To describe the sociodemographic and obstetric profiles of women with GH and PE.
  3. To document the clinical management practices, including:
    • Antihypertensive agents used (first-line, second-line, acute severe hypertension management)
    • Use of magnesium sulfate for seizure prophylaxis and treatment
    • Investigations performed (blood pressure monitoring frequency, urine protein assessment, haematological and biochemical workup, fetal surveillance)
    • Mode and timing of delivery
  4. To assess adherence to ISSHP 2021 / FOGSI / NICE guidelines for GH and PE management.
  5. To evaluate maternal outcomes including: severe hypertension, eclampsia, HELLP syndrome, pulmonary oedema, acute kidney injury, abruption placentae, postpartum haemorrhage, ICU admission, maternal mortality.
  6. To evaluate fetal and neonatal outcomes including: preterm birth, small for gestational age (SGA), intrauterine growth restriction (IUGR), fetal distress, APGAR scores, NICU admission, and perinatal mortality.
  7. To identify predictors of adverse maternal and fetal outcomes.
  8. To correlate the degree of guideline adherence with outcomes.

3. REVIEW OF LITERATURE

3.1 Global Burden

HDP complicates up to 10% of all pregnancies worldwide and are a major cause of maternal morbidity and mortality globally.⁴ PE affects 3-5% of all pregnancies and, in its severe forms including HELLP syndrome, can lead to acute renal failure, placental abruption, DIC, and maternal death.⁷ Globally, approximately 14% of maternal deaths are attributable to HDP.

3.2 Burden in India

HDP is reported in approximately 10-20% of all pregnant women across India. PE incidence is 8-10% (ICMR). In Asia and Africa, nearly one-tenth of all maternal deaths are associated with HDP (National Health Portal of India). Early management reduces not only the frequency of hypertensive complications but also neonatal complication rates.³ A prospective study from Bharati Hospital, Pune (n=1,330) found an overall HDP prevalence of 7.8%: PE 5.6%, GH 1.5%, eclampsia 0.6%, with methyldopa being the most commonly prescribed antihypertensive as monotherapy (17.3%) and in combination (28.8%).⁸

3.3 Classification and Diagnostic Criteria

The ACOG 2020 classification (reaffirmed 2023) and ISSHP 2021 are the principal frameworks currently in use. Gestational hypertension is defined as BP ≥140/90 mmHg on two occasions ≥4 hours apart, after 20 weeks of gestation, resolving by 12 weeks postpartum, in the absence of proteinuria or end-organ damage. Pre-eclampsia requires hypertension plus ≥1 of: proteinuria (≥300 mg/24h or protein:creatinine ratio ≥0.3, or urine dipstick ≥2+), new-onset renal insufficiency (serum creatinine >1.1 mg/dL), impaired liver function (transaminases >2× normal), thrombocytopenia (<100,000/µL), pulmonary oedema, or new-onset headache unresponsive to analgesia.
Severe features include: SBP ≥160 or DBP ≥110 mmHg on two occasions ≥4 hours apart; serum creatinine >1.1 mg/dL; platelet count <100,000/µL; elevated liver enzymes (≥2× upper limit of normal); severe right upper quadrant or epigastric pain; pulmonary oedema; or new-onset headache unresponsive to medication.

3.4 Antihypertensive Management

Current guidelines recommend initiating antihypertensive therapy for BP ≥140/90 mmHg. The NICE guideline (2019) recommends a target BP of 135/85 mmHg. First-line oral agents include labetalol, modified-release nifedipine, and methyldopa (methyldopa to be avoided in the first trimester and during postpartum). Acute severe hypertension (SBP ≥160 or DBP ≥110) requires prompt intravenous labetalol, intravenous hydralazine, or immediate-release oral nifedipine.⁵
A 2025 network meta-analysis (Hup et al., Am J Obstet Gynecol, PMID 40216176) evaluated oral antihypertensive treatment in pregnancy, providing updated comparative efficacy data across agents. The CHIPS trial established the safety and benefit of tight BP control (DBP target 85 mmHg) over less-tight control (DBP target 100 mmHg) regarding reduction of severe hypertension and maternal complications without additional fetal risk.⁶

3.5 Magnesium Sulfate

Magnesium sulfate is the drug of choice for both prevention and treatment of eclampsia. ACOG, ISSHP, and NICE all recommend its use in women with PE with severe features. The Magpie Trial established its superiority over placebo and diazepam in preventing eclampsia.

3.6 Timing of Delivery

Most major guidelines (NICE, ACOG, ISSHP, SOMANZ, FIGO) recommend delivery at or after 37 weeks for uncomplicated GH, supported by evidence from the HYPITAT trial demonstrating that induction of labour beyond 37 weeks is associated with improved maternal outcomes.⁵ For PE with severe features, delivery is recommended from 34 weeks onward. Expectant management of PE between 34 and 37 weeks may be considered in centres with appropriate monitoring facilities.

3.7 Fetal Surveillance

NICE and SOMANZ guidelines recommend ultrasound assessment of fetal growth, amniotic fluid volume, and umbilical artery Doppler velocimetry at diagnosis of GH and every 2-4 weeks thereafter. ACOG recommends growth measurement every 3-4 weeks with at least weekly amniotic fluid assessment. ISSHP emphasises that elevated uric acid levels require detailed fetal growth evaluation.

3.8 Postpartum Care

All women who experience GH or PE should be reviewed at 6 weeks postpartum (NICE, FIGO, SOGC). Those with persistent hypertension require medical review 1-2 weeks post-delivery. Women should be counselled regarding long-term cardiovascular risk, risk of recurrence in future pregnancies, and lifestyle modifications.

3.9 PLGF-Based Testing

NICE (updated April 2023) recommends offering placental growth factor (PlGF)-based testing between 20 and 35 weeks of gestation in women suspected of developing pre-eclampsia, to improve prediction and rule out PE in equivocal cases.⁵

4.8 Guideline Adherence Assessment

Adherence to ISSHP 2021 / FOGSI / NICE (2023) recommendations will be assessed using a structured checklist covering:
DomainGuideline RecommendationAdherent (Yes/No)
BP threshold for treatment initiationAntihypertensive started at BP ≥140/90 mmHg
First-line antihypertensiveLabetalol / nifedipine / methyldopa used
Acute severe HTN managementIV labetalol / hydralazine / oral nifedipine given within 30-60 minutes
MgSO4 prophylaxisGiven to all PE with severe features
Fetal growth assessmentUltrasound performed at diagnosis and every 2-4 weeks
Umbilical artery DopplerPerformed at diagnosis and serially
Timing of delivery - GHOffered delivery at ≥37 weeks
Timing of delivery - PE without severe featuresOffered delivery at ≥37 weeks
Timing of delivery - PE with severe featuresDelivery planned from 34 weeks
CorticosteroidsGiven for fetal lung maturity if <34 weeks and delivery planned
Postpartum reviewScheduled at 6 weeks postpartum
DocumentationBP target (135/85) documented
Each patient will receive an overall guideline adherence score (number of applicable criteria met / total applicable criteria × 100%). Adherence will be categorised as: low (<50%), moderate (50-74%), high (≥75%).

4.9 Statistical Analysis

Descriptive statistics:
  • Continuous variables: mean ± standard deviation (SD) or median (interquartile range) as appropriate.
  • Categorical variables: frequency and percentage.
Analytical statistics:
  • Comparison of outcomes between GH and PE groups: independent t-test / Mann-Whitney U test for continuous variables; chi-square test / Fisher's exact test for categorical variables.
  • Comparison between guideline-adherent and non-adherent groups for outcomes.
  • Logistic regression to identify predictors of adverse maternal and fetal outcomes.
  • Correlation between guideline adherence score and outcome parameters: Spearman's rank correlation.
Statistical significance will be set at p <0.05. Analysis will be performed using SPSS version 26 or IBM SPSS Statistics / Stata.

4.10 Ethical Considerations

  1. Ethical approval will be obtained from the Institutional Ethics Committee (IEC) prior to commencement.
  2. Written informed consent will be obtained from all participants in the prospective arm.
  3. For the retrospective arm, waiver of informed consent will be sought (review of anonymised records), in line with ICMR National Ethical Guidelines for Biomedical and Health Research 2017.
  4. Patient confidentiality and data security will be maintained; identifiers will be replaced by study IDs.
  5. The study is observational and will not alter or withhold any treatment.

5. OPERATIONAL DEFINITIONS

6. LIMITATIONS

  1. Retrospective arm relies on the quality and completeness of existing medical records; missing data may introduce information bias.
  2. Single-centre design limits generalisability to other settings with different resource availability or patient demographics.
  3. Guideline adherence is assessed against current recommendations; historical cases in the retrospective arm were managed under guidelines prevailing at that time, which may differ slightly from current recommendations.
  4. Confounding factors (e.g., co-morbidities, severity of presentation, gestational age at presentation) may influence both management decisions and outcomes; multivariate analysis will address this partially.
  5. Observational design cannot establish causality between guideline adherence and outcomes.

7. EXPECTED OUTCOMES AND SIGNIFICANCE

This study will generate data on:
  • Current prevalence and clinical profile of GH and PE in a tertiary care Indian setting.
  • Real-world antihypertensive prescribing patterns and their alignment with evidence-based recommendations.
  • Rates of maternal and perinatal complications and their association with management quality.
  • Quantified guideline adherence scores enabling identification of specific care gaps.
The findings will inform targeted quality improvement initiatives, continuing medical education, and protocol development at the institutional level. They will contribute to the limited but growing body of Indian literature on HDP outcomes and guideline implementation.
