The Rise of Science-Based Investigative Journalism New Tools and Techniques
Meanwhile,Gustavo Faleiros,the Brazil-based founder of InfoAmazonia,a regional environmental news site,is a big advocate of using satellite imagery and other remote sensing techniques to support an investigative science journalism approach known as geojournalism. “Our need to understand the environment makes this data source unable to capture an increasing proportion of deaths. Obituaries have been used for several decades as a mortality data source, for example, the field of occupational epidemiology has utilized this source, and it has been reported to have a high sensitivity. With obituaries becoming available online, their use increased as one of the sources for ascertaining mortality data and was shown to be a valid and reliable source, though it may be limited in sensitivity. We hypothesized that combining each of these six mortality data sources in a composite algorithm could provide a sensitive and specific measure for mortality that could be a reliable approach when NDI linkage is not possible. The main objective of our study is to assess the validity and completeness of six mortality data sources and a composite algorithm within the Healthcare Integrated Research Database (HIRD) compared to NDI data, ie, the gold standard, in the advanced-stage cancer patient population from 2010 to 2018.
Methods
This study was performed using data from the HIRD, which contains medical and pharmacy claims data from health plan members across the US. The HIRD is
Data Analysis
For each of the six death sources, the difference in days between the death dates from a death source and the NDI was calculated among members with a death date.
In addition, the mean and standard deviation (SD) of the difference in dates and the proportion of members in different categories of difference between the dates from death source and NDI was calculated.
the mean, standard deviation, and proportion of participants within categories of sex, age (validation metrics were calculated to assess the performance of internally available death sources.23,24)
- Se = proportion of NDI death with an identifiable death in a death source (True positives/(True positives + false negatives))
- Sp = proportion of patients without an NDI death and no identifiable death in a death source (true negatives/(True negatives + false positives))
- PPV = proportion of patients with an identifiable death in a death source and NDI death (True positives/(True positives + false positives))
- NPV = proportion of patients without death in the death source and no NDI death (true negatives/(True negatives + false negatives))
The 95% confidence intervals (95% CI) were calculated using the binomial method. Death dates from death sources were a match with an NDI if they occurred 60 days before or 30 days after the NDI date.
We created a composite death data algorithm that assigned a death if a death was recorded in any of the six death sources. The death date of the composite algorithm was assigned using the following hierarchy of death sources, based on:
a) the highest proportion of internally sourced dates with NDI dates for members who had dates from death source and NDI,
b) the proportion of members with internally sourced dates lacking an NDI date, and
c) the proportion of members with an NDI date where the internally sourced date occurred within ±30 days.
Advanced Cancer study Reveals Mortality Data Accuracy
In a complete study spanning a decade, researchers have delved into the accuracy and reliability of mortality data for advanced cancer patients. The findings, published in a recent medical journal, offer critical insights into how different data sources compare with the National Death Index (NDI).
Baseline Characteristics
The study population consisted of 27,396 advanced cancer patients from 2010 to 2018.Key findings from the baseline characteristics, as outlined in Table 1, indicate that 67.3% of the patients had at least one recorded death date. The average age of the cohort was 67.2 years, with a standard deviation of 13.5 years. Women constituted 54.3% of the study population, and 56.1% were commercially insured.
Patients with recorded death dates were notably older, averaging 69.1 years, compared to 63.1 years for those without death records. additionally,a higher proportion of these patients were male (49.7% vs. 37.4%) and had Medicare plans (49.8% vs. 32.5%).
Death Date Accuracy
The accuracy of death dates from various sources was meticulously analyzed. Table 2 reveals that the composite mortality data had an 84.7% exact match with the NDI death date. Among individual sources, the Centers for Medicare & Medicaid Services (CMS) and the University of Michigan (U.M.) showed the highest accuracy, with 99.3% and 91.5% exact matches, respectively. death matching File (DMF) and obituaries followed, with 86.1% and 70.1% exact matches, respectively.Discharge data had a 54.3% exact match, with 27.8% of deaths occurring one to seven days after the NDI date.Disenrollment data showed the least accuracy, with only 38.8% exact matches and 31.7% reported one to fifteen days earlier than the NDI date.
performance Metrics
The performance of the composite mortality database and individual death sources was evaluated using sensitivity, specificity, and positive predictive value (PPV). As detailed in Table 3, the composite mortality database demonstrated a sensitivity of 88.9% (95% CI = 88.5%, 89.3%), specificity at 89.1% (95% CI = 88.6%, 89.6%), and a PPV of 93.4% (95% CI = 93.1%, 93.7%).
Sensitivity Analysis
To assess the impact of the gap between internally sourced data and the NDI, different allowable gaps were used for sensitivity analysis: ±60, ±30, ±15, and ±7 days of the NDI date. These analyses were performed using SAS Enterprise Guide 8.3.
Conclusion
The study underscores the importance of accurate mortality data in healthcare research and planning. The composite mortality database proved to be a reliable source,with high sensitivity and specificity. However, variations in accuracy among different data sources highlight the need for careful consideration when interpreting mortality data.

This article is based on the study by Schwesinger et al. (2017) and incorporates insights from related research. In the intricate landscape of public health, understanding mortality trends is paramount for effective policy-making and resource allocation. Recent studies have shed light on various aspects of mortality, from the incidence of sepsis in U.S. hospitals to the validation of mortality data sources. Let’s delve into some of the key findings and their implications. A comprehensive study published in the JAMA journal in 2017 analyzed the incidence and trends of sepsis in U.S. hospitals using both clinical and claims data from 2009 to 2014. The research, conducted by Rhee et al.,revealed significant insights into the prevalence of sepsis. The study highlighted that sepsis cases had been on the rise during this period, underscoring the need for enhanced diagnostic and treatment strategies. the Centers for Disease Control and Prevention (CDC) has been closely monitoring in-hospital mortality rates among COVID-19 patients. Data from selected hospitals, accessible via the CDC’s website, show fluctuating mortality rates over time. These trends provide crucial information for healthcare providers and policymakers in managing the ongoing pandemic. The Morbidity and Mortality Weekly report (MMWR) published a study in 2020 that examined the percentage of deaths by place of death in the United States from 2000 to 2018.The findings, available in the MMWR,indicate shifts in where people are dying,with implications for end-of-life care and healthcare infrastructure. The reliability of mortality data is a critical concern for public health researchers. A study by Soowamber et al.,published in the Journal of Clinical Epidemiology in 2016,demonstrated that online obituaries can be a reliable and valid source of mortality data. This method offers a cost-effective and timely way to gather mortality information, especially in resource-limited settings. another study by Buonanno and Puca, featured in health Policy in 2021, explored the use of newspaper obituaries to “nowcast” daily mortality rates, particularly in the context of the Italian COVID-19 hot-spots. Their findings suggest that obituaries can provide valuable real-time data on mortality trends. The National Death Index (NDI) is a vital tool for mortality research. The Information Service, is another comprehensive database that aids in mortality research. Lerman et al., in their study published in the Journal of Clinical Oncology: Clinical Cancer Informatics, validated a mortality composite score in real-world settings. their work aimed to overcome source-specific disparities and biases, ensuring more accurate mortality data for research and policy purposes.

This method offers a cost-effective and timely way to gather mortality information, especially in resource-limited settings. another study by Buonanno and Puca, featured in health Policy in 2021, explored the use of newspaper obituaries to “nowcast” daily mortality rates, particularly in the context of the Italian COVID-19 hot-spots. Their findings suggest that obituaries can provide valuable real-time data on mortality trends. National Death Index and Death Master File The National Death Index (NDI) is a vital tool for mortality research. The Information Service, is another comprehensive database that aids in mortality research. Validating Mortality Composite Scores Lerman et al., in their study published in the Journal of Clinical Oncology: Clinical Cancer Informatics, validated a mortality composite score in real-world settings. their work aimed to overcome source-specific disparities and biases, ensuring more accurate mortality data for research and policy purposes.

This innovative approach aims to pinpoint populations at risk, thereby reducing the disease’s morbidity, mortality, and economic burden. A recent study published in the Journal of Affective Disorders has developed and validated a machine learning algorithm specifically designed to predict the risk of postpartum depression among pregnant women. The research, conducted by Zhang et al., underscores the potential of ML in enhancing the accuracy and efficiency of predictive models. By leveraging advanced algorithms, the study aims to provide healthcare providers with a more precise tool to identify women at risk, enabling timely intervention and support.the implementation of such ML models could significantly transform the way PPD is managed. Traditional methods of screening often rely on subjective assessments and general risk factors, which may not capture the nuances of individual patient experiences. machine learning, however, can analyze vast amounts of data to identify subtle patterns and predictors that might otherwise go unnoticed. This precision could lead to earlier detection and intervention, ultimately improving patient outcomes. Moreover, the economic implications of such advancements are substantial. Postpartum depression places a significant burden on healthcare systems, with costs associated with treatment, lost productivity, and societal impact. By using ML to identify at-risk populations,healthcare providers can allocate resources more effectively,targeting preventive measures and support services to those who need them most.As we move forward, the integration of machine learning in healthcare will continue to evolve. The challenge lies in ensuring that these models are not only accurate but also ethically sound and accessible to all patients.Collaboration between healthcare providers, data scientists, and policymakers will be crucial in realizing the full potential of these technologies.
