Recently, machine learning (ML) techniques have shown promise in predicting drug-related side effects earlier in the development pipeline. The objective of this policy brief was to propose evidence-based policy options for using ML techniques to predict drug-related side effects. This policy brief was developed upon a previously published scoping review of relevant studies. A secondary analysis synthesized key barriers and opportunities relevant to policy development. Key findings revealed some challenges in data standardization, interpretability, and regulatory alignment. Moreover, the results highlighted the potential of explainable ML and cross-sector collaboration to improve prediction accuracy and fairness. Five policy recommendations were proposed: (1) establishing standardized data collection and secure protocol sharing; (2) funding ML model development and rigorous validation; (3) integrating ML into drug development pipelines; (4) increasing public awareness through targeted education; and (5) implementing fairness regulations to address bias. These recommendations require joint efforts from governments, regulatory bodies, pharmaceutical firms, and academia to be implemented in practice. While ML offers transformative potential for drug safety, its real-world implementation faces ethical, regulatory, and technical hurdles. Policies must ensure model transparency, promote equity, and support infrastructure for ML adoption. Through interdisciplinary coordination and evidence-based policymaking, stakeholders can responsibly advance ML use in drug development to enhance patient outcomes.</p>","PeriodicalId":54976,"journal":{"name":"Inquiry-The Journal of Health Care Organization Provision and Financing","volume":"62 ","pages":"469580251335805"},"PeriodicalIF":1.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12166244/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144295392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A comprehensive search was conducted for peer-reviewed articles published between January 2004 and July 2024, utilizing the databases Web of Science, Scopus, PubMed, and Google Scholar. The Critical Appraisal Skills Program (CASP) assessment tool was employed to evaluate the quality of the studies following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for transparency. Out of approximately 966 818 articles retrieved, only 17 studies met the defined inclusion criteria. The findings highlighted effective strategies for delivering PC services in LMICs, including patient navigator-led programs, telemedicine, and home health care services. The review highlighted several interventions for PC services, including massage, Cancer and Living Meaningfully (CALM), and light therapies. However, it also identified significant challenges, such as the educational levels of caregivers, patient acceptance of PC services, logistical issues, medication side effects, and a preference for traditional healing practices. This systematic review highlights the critical need for effective PC services for cancer patients in LMICs, where cancer-related mortality rates remain alarmingly high. By synthesizing data from various studies, this analysis offers a comprehensive framework for developing successful palliative care initiatives in these regions. It emphasizes the importance of training caregivers of cancer patients to enhance their confidence in delivering palliative care services and counseling patients about the benefits of these services. Utilizing this information can help practitioners and policymakers improve palliative care services, ultimately enhancing the quality of life for cancer patients in LMICs.</p>","PeriodicalId":54976,"journal":{"name":"Inquiry-The Journal of Health Care Organization Provision and Financing","volume":"62 ","pages":"469580251325429"},"PeriodicalIF":2.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11967213/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143765956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This approach underlines the importance of active employee involvement, which is consistent with the principles of a healthy organisation. An exploratory, convergent, mixed-methods pilot study combined qualitative and quantitative data collection. The questionnaire included demographic and work-related characteristics, an open-ended question on the definition of a healthy shipping company from a personal perspective, and scaled ratings of key determinants of healthy shipping companies identified through a literature review. The sample consisted of 309 participants from the international shipping sector, including 238 seafarers and 71 shipping company managers. The study identified key factors that contribute to a healthy shipping company, with both seafarers and managers recognising the importance of employee well-being, safety, work-life balance, and a supportive organisational culture. These findings were consistently reflected in both the quantitative and qualitative data. The qualitative results also revealed group-specific perspectives: managers highlighted the importance of financial management, strategic innovation, and corporate governance, while seafarers placed greater emphasis on immediate working conditions and mutual respect.

Evidence links nursing to patient outcome disparities. Conceptual frameworks addressing health inequities, however, overlook nursing factors including staffing, work environment, and structural factors. This paper addresses this gap by presenting a framework postulating nursing system factors as contributors to inequities, distinguishing it from frameworks focusing mainly on individual or social determinants. The literature demonstrates that hospitals with better nurse staffing and work environments have lower mortality and complication rates, particularly among vulnerable populations. Additionally, nursing factors vary by hospital and correlate with patient racial composition and outcomes. Authoritative reports and frameworks on healthcare disparities from the National Academies of Sciences, Engineering, and Medicine and the National Institute on Minority Health and Health Disparities were reviewed. The role of nursing in each was summarized. Kilbourne et al.'s framework was adapted to propose that disparities in patient outcomes are shaped by the organizational context of nursing, for example, nurse staffing, work environment, structural competence, and the patient-nurse clinical encounter. Nursing's impact on equitable care and outcomes should be central to health disparity frameworks. This framework implies that policymakers include nursing elements in equity performance measures and incentivize them through payment systems. Administrators should consider nursing system features as integral to equitable care. Research on the framework assertions is warranted to inform health equity strategies through nursing. By highlighting mechanisms through which nursing factors contribute to disparities, this framework motivates health equity research and policy in acute care settings.</p>","PeriodicalId":54976,"journal":{"name":"Inquiry-The Journal of Health Care Organization Provision and Financing","volume":"62 ","pages":"469580251372763"},"PeriodicalIF":2.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12441289/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145071113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
