Missed medication doses in long-term care facilities compromise resident safety and arise from intersecting medication, resident, staffing, route, and workload factors. These risks are especially important where residents have complex regimens and high care dependency. Current medication safety approaches in long-term care are often retrospective, audit-based, or broadly applied across all residents. They do not forecast which specific resident–medication pass combinations are most vulnerable before administration occurs. The objective is to describe a predictive model that could estimate the probability of a missed medication dose for each resident–medication pass combination. The model would use medication complexity, resident dependency, staff availability, administration route, and shift-level workload indicators. A supervised classification approach could be trained using electronic medication administration records, staffing rosters, resident assessment data, and medication order characteristics. The model would output a dose-level missed-dose risk score before the relevant medication pass. Conceptually, the model would identify high-risk medication–resident–shift triples and provide an interpretable explanation of dominant risk contributors. For example, the system could flag a non-oral high-risk medication scheduled during a low-staffed morning medication round. Such a model could support proactive prevention by directing nursing attention toward the most vulnerable doses before they are missed. It could also inform shift-level workload planning and safer medication pass organization.
Failure to follow up after abnormal screening results is a persistent ambulatory safety problem. Because the diagnostic process often spans patient notification, scheduling, primary care review, and reminder outreach, delays may emerge gradually before they become visible in registry reports. Existing care gap reports commonly classify results as closed or open after a defined time window. This retrospective framing limits the ability to detect patients who are currently moving toward delayed diagnostic resolution. The objective of this article is to describe a predictive model that estimates the probability of delayed diagnostic follow-up after an abnormal screening result. The proposed model integrates patient engagement signals, scheduling activity, clinician workload, result severity, and reminder history. The model would use a gradient-boosted classification framework trained on historical abnormal results and longitudinal care-process features. Inputs would be extracted from patient portals, scheduling systems, primary care workload records, laboratory and radiology result metadata, and reminder logs. Conceptually, the model would generate a daily updated risk score for each unreconciled abnormal result. It would also identify the dominant drivers of risk, such as unread portal messages, repeated appointment cancellations, limited primary care availability, high-severity findings, or escalating reminder activity. A predictive approach could shift delayed follow-up management from retrospective audit to proactive prioritization. By identifying patients at greatest risk before the diagnostic window closes, care teams could better allocate outreach and navigation resources.
