Special Issue Information

Dear Colleagues,

The digital revolution has brought about huge amounts of digitized information. Quantitative techniques founded upon rigorous statistical and mathematical theories have always been a key foundation in the advancement of health services. Statistical theory and modern machine learning are deeply intertwined. The potential for overcoming challenges confounding healthcare and health service delivery through these computational domains has been proven time and again across the entire value chain of health and healthcare. 

The Institute of Medicine (IOM) proposed the Quadruple Aims in looking at the complex challenges underpinning health services across the tradeoffs in cost effectiveness, population health, patient experience, and provider well-being. Healthcare being a complex human-centric service industry, there has always been an emphasis on a holistic understanding of the systems implications in any proposed new interventions. The voluminous and rapid generation of the data from digitized systems has introduced immense possibilities in the advancement of health services using statistical theory and machine learning. 

Health-related data could come from electronic health records (EHRs), procurement systems, social media, public health reports, non-profit and global organizations (e.g., WHO, UN), scientific publications, and insurance organizations, among others. Although the ubiquity of data is indisputable, the availability of quality data that contain the necessary depth and breadth of coverage to positively impact care is still frequently an issue for researchers and practitioners in the health services research domain. Data from different sources must usually be pooled together in a meaningful and rigorous way to generate insightful analysis and impactful results. Consequently, numerous data consortiums and ground-up multi-site research and data collaboratives have been established to realize the immense opportunity present in large-scale databases that cut across borders, peoples, and health systems. 

This Special Issue will cover topics that span the entire spectrum from data curation, extraction, wrangling, analysis, and insight generation to implementation and deployment of data-centric interventions or policy recommendations founded upon rigorous statistical theory and machine learning techniques. Research areas may include (but are not limited to) the following:

  • Data science and artificial intelligence in health services and medicine;
  • Statistical theory and applications in health services;
  • Applications of machine learning in healthcare;
  • Application of survival analysis and stochastic models in healthcare;
  • Statistical theory/machine learning for decision making in healthcare;
  • Statistical and machine learning innovations for clinical decision support systems;
  • Epidemiology and public health;
  • Medical informatics;
  • Value-based healthcare;
  • Data-driven innovations in cloud computing for health services;
  • Big data analytics for health services and population health;
  • Data-driven methods and models for health service improvement;
  • Security and privacy innovations for health data;
  • Innovations in federated learning for multi-site collaborations;
  • Predictive modeling and risk scores;
  • Innovations in data wrangling and feature engineering for big data modeling;
  • Multi-model data analytics for health services;
  • Patient safety and quality.

Delays in the assessment, management, and treatment of lung cancer patients may adversely impact prognosis and survival. This study is the first to use machine learning techniques to predict the quality and timeliness of care among lung cancer patients, utilising data from the Victorian Lung Cancer Registry (VLCR) between 2011 and 2022, in Victoria, Australia. Predictor variables included demographic, clinical, hospital, and geographical socio-economic indices. Machine learning methods such as random forests, k-nearest neighbour, neural networks, and support vector machines were implemented and evaluated using 20% out-of-sample cross validations via the area under the curve (AUC). Optimal model parameters were selected based on 10-fold cross validation. There were 11,602 patients included in the analysis. Evaluated quality indicators included, primarily, overall proportion achieving “time from referral date to diagnosis date ≤ 28 days” and proportion achieving “time from diagnosis date to first treatment date (any intent) ≤ 14 days”. Results showed that the support vector machine learning methods performed well, followed by nearest neighbour, based on out-of-sample AUCs of 0.89 (in-sample = 0.99) and 0.85 (in-sample = 0.99) for the first indicator, respectively. These models can be implemented in the registry databases to help healthcare workers identify patients who may not meet these indicators prospectively and enable timely interventions. Full article

Abstract

Without accounting for this feature, the forecast mortality rates of the popular Lee–Carter (LC) model are less reliable in the long run. [...] Read more.
Influential existing research has suggested that rather than being static, mortality declines decelerate at young ages and accelerate at old ages. Without accounting for this feature, the forecast mortality rates of the popular Lee–Carter (LC) model are less reliable in the long run. To provide more accurate mortality forecasting, we introduce a time-varying coefficients extension of the LC model by adopting the effective kernel methods. With two frequently used kernel functions, Epanechnikov (LC-E) and Gaussian (LC-G), we demonstrate that the proposed extension is easy to implement, incorporates the rotating patterns of mortality decline and is straightforwardly extensible to multi-population cases. Using a large sample of 15 countries over 1950–2019, we show that LC-E and LC-G, as well as their multi-population counterparts, can consistently improve the forecasting accuracy of the competing LC and Li–Lee models in both single- and multi-population scenarios.
