Development and Evaluation of a Generative AI Chatbot for Database Searching in Systematic Review

ABSTRACT

Introduction

Systematic reviews (SRs) require comprehensive, reproducible searches, yet developing search strategies is resource-intensive and demands specialized expertise. Generative AI offers potential to streamline this process, but empirical evaluations for GAI-assisted SR searching remain scarce. The objectives of this study are to: demonstrate a step-by-step process for developing a custom ChatGPT-based chatbot to support SR search strategy development, and evaluate its performance.

Design

A cross-sectional evaluation study.

Methods

We used ChatGPT-4.0 to create a chatbot designed to mimic a medical librarian, generating PICO-informed searches. Its knowledge base was augmented with two methodological references. After piloting testing, we refined its instructions. For evaluation, we randomly sampled 50 Cochrane SRs published in 2024. Standardized P–I–O prompts produced database-ready queries for PUBMED and EMBASE. The primary outcome was per-review success rate, summarized by median and inter-quartile range. A sensitivity analysis was conducted.

Results

Pilot testing achieved a retrieval rate of 41/49 (83.7%). In the main sample (1169 studies; median 13.5 studies per SR), the chatbot identified a median of 67.4% of included studies (IQR: 43.1%–88.4%). When limited to indexed studies (n = 1114), retrieval rose to 72.0% (IQR: 46.0%–92.5%). Lower performance was observed when outcomes were absent from the abstracts or interventions had many lexical variants.

Conclusions

A GAI-based chatbot can rapidly generate SR searches (~67%–72% identification), serving as a useful starting point but not a replacement for expert-led approaches. Integration of librarian expertise, structured prompts, and controlled vocabularies may improve performance. Further benchmarking and transparent reporting are needed to guide adoption.

Disaggregating innovation for sustainable development in ASEAN: Panel evidence on the moderating role of government effectiveness

by Pureheart Ogheneogaga Irikefe, Mohammad Falahat, Ahmad Danial Zainudin, Ihtisham Ullah, Nohman Khan, Bernard Ojonugwa Anthony

With progress toward the 2030 Agenda faltering, many see innovation as a key to sustainable development. The Association of Southeast Asian Nations (ASEAN) bloc represents a unique opportunity to examine how innovation capabilities drive sustainability in diverse economic and developmental contexts. Using panel data for ASEAN countries from 2011 to 2022, this study breaks down innovation into the seven pillars of the Global Innovation Index (GII) and investigates their impact on the Sustainable Development Goal (SDG) Index; with the objective of identifying which GII pillars most strongly predict SDG, while examining the moderating role of government effectiveness and controlling the impacts of gross national income per capita and foreign direct investment. Fixed effects models were used to analyse the data and supplemented by Driscoll-Kraay standard errors, addressing unobserved heterogeneity and cross-sectional dependence. Results reveal that only Institutions and Infrastructure pillars exert a consistently positive impact on SDG performance. In contrast, Creative Outputs have a negative impact. Importantly, Government Effectiveness reverses the negative impact of Creative Outputs, so that this pillar becomes positive for SDG achievement, without significant moderation of the other six GII pillars when controlling for year effects. In conclusion, these findings contest the efficacy of universal innovation policies and underscore the imperative for nuanced, context‑specific ones. It is recommended that ASEAN governments prioritize institutional and infrastructural investments and develop tailored regulatory frameworks, such as green intellectual property regimes and digital economy standards, to harness the creative economy for inclusive, sustainable growth by explicitly integrating innovation strategies with governance reforms.

Introduction

Cutaneous T cell lymphoma (CTCL) is a group of non-Hodgkin lymphomas that primarily affects the skin and can mimic inflammatory dermatoses. Unlike many skin diseases, CTCL can lead to disabling symptoms, and advanced CTCL can even be fatal. Early studies investigating health-related quality of life (HRQOL) in patients with mycosis fungoides (MF) and Sézary syndrome (SS), common subtypes of CTCL, demonstrated significant impairment across numerous domains. The aim of this current study is to develop a core domain set (CDS) to identify the essential aspects of MF/SS that influence HRQOL that should be measured in therapeutic clinical trials. In the future, this set of core concepts will be used to identify the best patient- reported outcome measure(s) (PROM) for HRQOL for MF/SS clinical research.

Methods and analysis

Multiple strategies will be used to generate candidate concepts: systematic review of the literature, qualitative study and a survey study of healthcare providers. A Delphi consensus process including a comprehensive group of stakeholders (patients, caregivers/care partners, a multidisciplinary group of healthcare professionals, patient advocacy groups, pharmaceutical industry representatives, methodologists and government agencies) will be used to achieve consensus. Statistical corrections for multiple significance testing and false positive findings will be undertaken.

Ethics and dissemination

The study was submitted for and received institutional review board approval at the University of Washington (IRB# STUDY00018890 and STUDY00019407). Informed consent will be obtained from all participants where necessary. We will disseminate our findings through peer-reviewed, open access publications and presentations at national/international conferences. We will provide a plain language summary in lay terms for patients and families to patient advocacy groups for distribution to their network.

Registration details

The protocol is registered in the Core Outcome Measures in Effectiveness Trials (COMET) database.

Attitudes, awareness and experience of Italian women undergoing non-invasive prenatal testing (NIPT): a nationwide cross-sectional study

Por: Godino · L. · Nardi · E. · Lanzoni · G. · Pompilii · E. · Calabrese · S. · Bertonazzi · B. · Carrara · M. · Gazineo · D. · Turchetti · D.
Objectives

Despite the increasing availability of non-invasive prenatal testing (NIPT), women’s experiences and motivations remain largely unknown. The use of NIPT is increasing in Italy; however, its organisation and access paths vary considerably. Women may undergo testing in either public or private facilities, where differences in pretest information, testing procedures and result communication may influence their experience. This study aims to investigate the attitudes, awareness and experiences of Italian women undergoing NIPT.

Design

A cross-sectional anonymous online survey was conducted via social media in the period March–August 2023.

Setting

This nationwide study was conducted in Italy.

Participants

Women over 18 years old who had undergone NIPT were included.

Results

Responders were 4154 women from every part of Italy. Most participants perceived the information provided during pre-NIPT counselling as extremely/very clear (68.2%) and helpful (72.5%), with higher proportions observed when counselling was delivered by geneticists. The mean knowledge score was 12.3 (range: 0–15) and was statistically higher for women with higher education level and prior NIPT experience. Half of the women reported no change in their perceived risk of having a child with chromosomal abnormalities after pre-NIPT counselling, and risk perception reduction was associated with lower knowledge scores. Pretest negative emotions were common (54.9%) and influenced by testing context, information sources and reasons for testing. Most women reported a positive impact from results (92.7%), shaped by information delivery made and prior knowledge. Regret was rare (3.0%) and linked to reasons and perceived risk changes. Overall, satisfaction was high (97.3%), particularly among those prioritising informed decision-making.

Conclusions

Improving personalised counselling and education throughout the NIPT journey seems crucial to minimise negative emotional impacts, highlighting the need for well-trained healthcare professionals.

Optimising delivery models for evidence-based interventions to reduce stillbirth in Punjab, India: a study protocol for implementation research

Por: Gautam · D. · Pandey · A. K. · Banerjee · R. · Saroha · E. · Gupta · U. · Thalakiya · R. · Dutta · S. · Bharadwaj · S. · K · R. · Gupta · M. · Sawhney · I. K. · Aggarwal · A. K. · Neogi · S. B.
Background

Stillbirth remains a major global health challenge, with India bearing a substantial share of the burden. Despite the availability of evidence-based interventions, stillbirth rates (SBRs) remain high due to gaps in healthcare access, quality and the effective delivery of maternal and neonatal care. This study aims to develop and implement an optimised, context-specific model to reduce SBRs in Sangrur district, Punjab.

Methods and analysis

This mixed-methods implementation research will adopt a sequential explanatory design. The study will be conducted over 3 years in four blocks of Sangrur. Data will be collected through baseline and endline surveys, verbal autopsies of stillbirths, direct observations of antenatal and intrapartum care, and qualitative interviews with community members and healthcare providers. The intervention package will focus on preconception and antepartum care, intrapartum care and strengthening health systems. The study will use the plan-do-check-act model for continuous improvement, and real-time data collection through electronic systems will support timely decision-making.

The study expects to achieve a 25% reduction in SBRs through the optimised delivery of high-quality antenatal and intrapartum care services. Additionally, the research will provide critical evidence on the barriers and facilitators to optimise service delivery, as well as insights into the health system and community factors influencing stillbirth outcomes. This study aims to create a scalable and adaptable intervention model to reduce SBRs in low-resource settings like Sangrur and Punjab. The findings will inform future maternal and neonatal health policies and provide a framework for the broader implementation of similar interventions in other regions of India.

Ethics and dissemination

The study protocol has been approved by the International Institute of Health Management Research, Delhi (IIHMR) Institutional Ethics Committee (IRB/2024-2025/01). The study is funded through a competitive call for proposals on stillbirths by the Indian Council of Medical Research (ICMR) under the National Health Research Priority Projects (5/7BMIPR/2022-RBMCH). The research has been awarded by ICMR (project ID NHRP05586) to IIHMR under grant number 5/7/BMIPR/2022-RCN.

Adaptation of the serious illness conversation guide to a multicultural context in Singapore: a qualitative study

Por: Ramakrishnan · C. · Lee · A. S. Y. · Malhotra · C. · Phua · G. L. G. · Yee · A. · Neo · S. H.-S.
Objective

To adapt the Serious Illness Conversation Guide (SICG), Ariadne Labs, Massachusetts USA, to a local Singapore version and evaluate its acceptability.

Design

Qualitative study using semistructured interviews.

Participants

49 participants (30 patients with serious illnesses, five family caregivers and 14 healthcare providers (HCP)) recruited from three public hospitals in Singapore.

Setting

Face-to-face or virtual indepth interviews.

Methods

Guided by the Heuristic Framework and Cultural Sensitivity model, we employed a multi-stage iterative design. Starting with the original SICG, we iterated the guide following three rounds of cognitive interviews among patients followed by expert consultation (n=4) to derive a local version, subsequently reviewed by caregivers and HCP. We assessed acceptability of the SICG using traffic light colour codes—red (unacceptable), orange (needs change) and green (no change) and gathered suggestions to rephrase them. Using content analysis, we compared acceptability of questions as proportion of red, orange and green responses at each interview round and inductively derived themes reflecting views towards the guide.

Results

The original SICG showed low acceptability, and most questions received high proportions of red responses. Negative words and phrases dampening hope, lack of comprehension due to complex framing and cultural insensitivity to prognostic discussions were key themes reflecting low acceptability. Surface and deep structural revisions that centred around positive framing with hopeful language, focusing on current values and individualising conversations (‘use if appropriate’ prompts) significantly improved the guide’s acceptability.

Conclusion

We derived a local Singapore SICG that aligns with the core elements of the original guide and fosters cultural sensitivity. The adapted version could be further tested in other Asian countries.

Prevalence and risk of adverse intrapartum-related outcomes in Uganda: a cross-sectional study with nested case-control

Introduction

Intrapartum-related complications are a leading cause of adverse perinatal outcomes, including stillbirths, neonatal deaths and intrapartum-related neonatal encephalopathy (IP-NE). We assessed the prevalence of adverse intrapartum-related outcomes, evaluated the association between IP-NE and obstetric and fetal risk factors, and examined whether emergency referral and emergency caesarean section (CS) modified this association through interaction effects.

Design

Cross-sectional with a nested case–control study.

Setting

Two hospitals in rural Eastern Uganda.

Population

Women giving birth to a live or stillborn baby weighing >2000 g between June and December 2022.

Methods

We used prospectively collected perinatal e-registry data to assess the prevalence of adverse perinatal outcomes. Logistic regression with interaction with postregression margins analysis was used to determine the association between IP-NE and emergency referral and emergency CS across risk groups of hypertensive disorders, antepartum haemorrhage, prolonged/obstructed labour and birth weight.

Main outcome measures

Adverse perinatal outcomes were stillbirths, 24-hour neonatal deaths and IP-NE (defined as Apgar score

Results

Of 6550 births, 10.2% had an adverse perinatal outcome: 3.8% stillbirths, 0.6% neonatal deaths and 5.7% IP-NE. Adverse outcomes were higher among neonates whose mothers had antepartum haemorrhage (31.3%) or prolonged/obstructed labour (27.2%) compared with those whose mothers had no complications. Emergency referral and CS did not change the association between IP-NE and obstetric risk, except in prolonged/obstructed labour. Without emergency CS, the predicted probability of IP-NE was 0.73 (95% CI 0.51 to 0.95); with CS, it decreased to 0.45 (95% CI 0.39 to 0.50).

Conclusions

Neonates born to mothers with obstetric complications had low healthy survival rates. Emergency referral and CS did not alter the risks of IP-NE in women with obstetric complications except for obstructed or prolonged labour, highlighting that these interventions may not be implemented with sufficient timeliness or quality, and/or that additional, more targeted strategies beyond referral and CS are needed to address IP-NE.

Objective

To investigate whether gestational diabetes mellitus (GDM) was associated with survival without bronchopulmonary dysplasia (BPD) in very preterm infants (VPIs).

Design

Retrospective multicentre cohort study.

Setting

A total of 79 neonatal intensive care units across China, January 2019 to December 2021.

Participants

A total of 23 752 VPIs (

Main outcome measures

The primary outcomes are survival without BPD at 36 weeks’ postmenstrual age (PMA) and its components.

Results

Infants exposed to GDM were associated with a higher rate of survival without BPD (aOR 1.12, 95% CI 1.04 to 1.21) at 36 weeks PMA and lower mortality (aOR 0.75, 95% CI 0.64 to 0.84) before 36 weeks PMA than unexposed infants. However, no significant association was observed between GDM and BPD at 36 weeks PMA (aOR 0.94, 95% CI 0.87 to 1.02), respiratory distress syndrome, need for advanced resuscitation or mechanical ventilation. After propensity score matching, GDM-exposed VPIs maintained higher survival without BPD (aOR 1.13, 95% CI 1.02 to 1.26) and lower mortality (aOR 0.81, 95% CI 0.68 to 0.97). These associations were strongest in infants born before 28 weeks (aOR 1.32, 95% CI 1.11 to 1.57) and those small for gestational age (aOR 1.41, 95% CI 1.11 to 1.80).

Conclusions

GDM was not associated with worsened BPD in VPIs. The positive association with survival and survival without BPD warrants could reflect a selection bias.
