Brief summary

In a retrospective program evaluation across 13 semesters, a standardized, experiential medication dosage calculation program that combined instruction, simulation, and assessment was associated with significantly higher first-attempt pass rates among nursing students than the period before it was introduced.

What NurseJet pulled from the source

Medication dosage calculation errors are a persistent patient-safety concern and a barrier to nursing student progression, and this program had seen significant declines in pass rates, with more than half of students across program levels failing their initial dosage calculation assessments. Educators at a nursing program implemented a standardized, experiential dosage calculation initiative that integrated instruction, simulation, and assessment, then conducted a retrospective evaluation of medication dosage calculation outcomes across 13 semesters, comparing the 4 semesters before implementation with the 9 semesters after. First-attempt pass rates were compared using a t test to assess program-level change over time. Mean semester-level pass rates were significantly higher after implementation (t(3.79) = -4.18, P = 0.016), and the post-implementation semesters consistently met or exceeded the program benchmark. The authors conclude that a standardized, experiential approach to dosage calculation instruction was associated with sustained improvements in program-level outcomes and offers practical guidance for nurse educators seeking data-driven curricular changes that support medication safety and student progression.

Why this matters for nurses

Dosage calculation competency underpins safe medication administration, yet many nursing students struggle to pass these assessments, which can delay progression and signal a downstream safety risk. This study may matter for nurse educators and new nurses because it links a structured, hands-on teaching approach to sustained improvement in first-attempt pass rates.

Bedside takeaway

Worth knowing that a standardized, hands-on dosage calculation program was linked to higher first-attempt pass rates for nursing students across 13 semesters.

Key takeaways

More than half of students across program levels had been failing their initial medication dosage calculation assessments before the change.
Educators introduced a standardized, experiential dosage calculation program combining instruction, simulation, and assessment.
A retrospective evaluation compared 4 pre-implementation semesters with 9 post-implementation semesters using a t test.
Mean semester-level first-attempt pass rates were significantly higher after implementation (t(3.79) = -4.18, P = 0.016) and consistently met or exceeded the program benchmark.

Practice implications

For nurse educators and preceptors, the findings suggest that building dosage calculation skills through repeated, experiential practice tied to instruction, simulation, and assessment, rather than one-off lessons, may raise competency and support medication safety. For students and new graduates, it reinforces that dosage calculation is a skill strengthened by structured practice over time.

Limitations & cautions

This was a retrospective, single-program evaluation comparing pass rates before and after one curricular change, without a separate control group, so other factors over the 13 semesters could have contributed. Because it reports program-level pass rates rather than individual student outcomes or actual medication errors at the bedside, it does not show whether the gains reduced real-world administration errors.

In a retrospective study of 728 acute-care stroke hospitalizations, nursing complexity (the number of nursing diagnoses) and nursing intensity (the number of nursing actions) differed across ischemic stroke, hemorrhagic stroke, and transient ischemic attack, with hemorrhagic stroke showing the highest intensity and transient ischemic attack the lowest.

Emergency LeadershipAI summaryReview source

Research ArticleResearchStaffing & WellbeingAI summary · original source linked below

Ischemic stroke, hemorrhagic stroke, and transient ischemic attack (TIA) differ in medical severity, but it has been unclear whether those differences show up in how much nursing work each requires. This retrospective study analyzed routinely collected nursing and administrative data from one acute care hospital, classifying hospitalizations as ischemic stroke, hemorrhagic stroke, or TIA using ICD-9-CM codes. Nursing complexity was measured as the number of nursing diagnoses documented within 24 hours of admission, and nursing intensity as the number of nursing actions recorded during the hospitalization, with group differences tested using ANOVA and Kruskal-Wallis tests. A total of 728 hospitalizations were included (429 ischemic strokes, 236 hemorrhagic strokes, and 63 TIAs), with 4,136 nursing diagnoses and 27,528 nursing actions recorded. Nursing diagnosis counts differed significantly (F = 5.81, P = 0.003), with TIA showing lower counts than both ischemic and hemorrhagic stroke and no significant difference between ischemic and hemorrhagic stroke. Nursing action counts also differed significantly (H = 16.73, P less than 0.001), highest in hemorrhagic stroke, intermediate in ischemic stroke, and lowest in TIA. In a sensitivity analysis standardized by length of stay, nursing intensity still differed significantly across categories (H = 12.999, P = 0.002), though the pattern differed from the cumulative counts. The authors conclude that standardized nursing data may complement medical indicators by capturing additional dimensions of patient needs and care delivery in people with stroke.

Key takeaways

The study reviewed 728 acute-care stroke hospitalizations (429 ischemic, 236 hemorrhagic, and 63 TIA), with 4,136 nursing diagnoses and 27,528 nursing actions recorded.
Nursing complexity, measured as nursing diagnoses within 24 hours of admission, differed across subtypes (F = 5.81, P = 0.003), with TIA lower than both stroke types and no significant difference between ischemic and hemorrhagic stroke.
Nursing intensity, measured as nursing actions during the stay, followed a clear gradient (H = 16.73, P less than 0.001): highest in hemorrhagic stroke, intermediate in ischemic stroke, and lowest in TIA.
Nursing intensity still differed after standardizing by length of stay (H = 12.999, P = 0.002), suggesting the gradient is not just a function of longer admissions.

Why this matters on shift

Stroke subtypes are usually described by their medical severity, but the day-to-day nursing workload they generate is less well quantified. This study may matter for neuro and stroke nurses because it uses standardized nursing language to show that hemorrhagic stroke tends to demand the most nursing actions, which can inform how acuity and assignments are weighed on the unit.

Bedside takeaway

Worth knowing that in a 728-admission records study, hemorrhagic stroke was linked to the highest bedside nursing intensity and TIA the lowest, so stroke subtype may track with how much hands-on nursing a patient needs.

Nursing implications

For neuroscience and stroke nurses, the findings reinforce that hemorrhagic stroke patients tend to carry the heaviest hands-on nursing load, while TIA patients generally require the least, which can help teams anticipate workload and advocate for appropriate assignments. Because complexity was similar between ischemic and hemorrhagic stroke while intensity was not, the number of nursing problems on admission may not, on its own, predict how much bedside work a stroke patient will need.

Limitations & cautions

This was a single-center retrospective study using routinely collected data and ICD-9-CM coding, so its findings depend on local documentation practices and may not generalize to other hospitals or nursing languages. It measured counts of nursing diagnoses and actions rather than patient outcomes, so it does not show whether higher nursing intensity changed how patients fared.

In a multicentre randomised controlled simulation trial with 82 nurses, independent double-checking detected more medication administration errors than single-checking overall, but the benefit was limited to experienced nurses, with no significant improvement among nurses with under five years of experience.

Med-Surg PedsAI summaryReview source

Research ArticleResearchMedication SafetyAI summary · original source linked below

Double-checking medication administration is a common hospital safety practice, and independence between the two checkers is thought to be the key to its effectiveness, yet there has been no empirical evidence that independent double-checking (IDC) detects errors better than a single-nurse check. This multicentre randomised controlled simulation trial enrolled 82 nurses from two paediatric hospitals in 41 two-hour simulations, each involving two nurses who administered medication sets containing embedded errors under both single-checking and IDC conditions, with condition order and medication sets randomised. Across 1,160 dose administrations with 640 error-detection opportunities, nurses detected 72.2 percent of errors (95 percent CI 68.6 to 75.5). Overall, IDC yielded an 11 percent higher error detection rate than single-checking (adjusted incidence rate ratio 1.11, 95 percent CI 1.01 to 1.21, P = 0.02; 77.7 percent for IDC versus 66.3 percent for single checks). That benefit was limited to experienced nurses: among early career nurses (under 5 years of experience) IDC produced no significant improvement (adjusted incidence rate ratio 0.98, 95 percent CI 0.86 to 1.11, P = 0.7), while experienced nurses showed a 26 percent improvement (adjusted incidence rate ratio 1.26, 95 percent CI 1.11 to 1.44, P less than 0.001). Evidence of social loafing was seen, particularly among early career nurses, whose detection was 26.0 percent higher when single-checking than in the role of first checker in IDC, and IDC required significantly more time (mean difference 4.96 minutes per medication set, P less than 0.001). The authors conclude that, given its inconsistent benefits, resource demands, and susceptibility to social loafing, IDC may be unsuitable as a universal safety strategy, and that strengthening single-checking competence and clinical judgement may be a more effective, scalable approach.

Key takeaways

In 41 two-hour simulations, 82 nurses from two paediatric hospitals administered medication sets with embedded errors under both single-checking and independent double-checking conditions.
Overall, independent double-checking detected 11 percent more errors than single-checking (adjusted incidence rate ratio 1.11, 95 percent CI 1.01 to 1.21, P = 0.02; 77.7 percent versus 66.3 percent).
The benefit was limited to experienced nurses (26 percent improvement, P less than 0.001); among nurses with under five years of experience there was no significant improvement (P = 0.7).
Independent double-checking took about 5 minutes longer per medication set (mean difference 4.96 minutes, P less than 0.001), and social loafing lowered early career nurses' detection in the first-checker role.

Why this matters on shift

Independent double-checking is widely mandated and consumes considerable nursing time, yet its real benefit has been assumed rather than measured. This study may matter for nurses and safety leaders because it provides direct evidence that the practice helps experienced nurses catch errors but does not reliably help less experienced ones, which challenges applying it as a blanket rule.

Bedside takeaway

Be aware that in a simulation trial, independent double-checking caught more medication errors than single-checking only for experienced nurses, with no benefit for nurses under five years and signs of reduced individual vigilance when checking in pairs.

Nursing implications

For nurses and unit leaders, the findings suggest that independent double-checking is not automatically safer for every nurse or situation and can be undermined by social loafing, where a second checker relaxes their own vigilance. The results support investing in each nurse's own checking competence and clinical judgement, and reserving double-checks for the highest-risk medications, rather than treating a second signature as a guaranteed safety net.

Limitations & cautions

This was a simulation trial rather than a study of real bedside administration, so behavior with actual patients and consequences may differ, and it involved 82 nurses from two paediatric hospitals, which may limit how far the results extend to adult or other settings. Detecting deliberately embedded errors in a study scenario may not fully reflect the interruptions and workload of everyday practice.

In a single-center quasi-experimental study of 60 inpatients at pressure injury risk, adding a structured Interaction Model of Client Health Behavior nursing program to routine care was associated with fewer new pressure injuries and more wound healing at 3 months than routine care alone.

Med-SurgAI summaryReview source

Research ArticleResearchQuality ImprovementAI summary · original source linked below

This non-randomized, non-equivalent control group study at one Chinese hospital enrolled 60 inpatients who had a pressure injury or were at high risk for one between June 2022 and June 2023. Patients were allocated by admission period to routine care or to nursing based on the Interaction Model of Client Health Behavior (IMCHB) for 3 months. Outcomes were measured with a caregiver pressure injury knowledge questionnaire, the Generic Quality of Life Inventory-74, dynamic observation for new pressure injuries, the Pressure Ulcer Scale for Healing (PUSH), and a nursing satisfaction scale. Baseline characteristics were comparable between the groups. After 3 months, the intervention group had higher caregiver knowledge scores than the control group (31.90 plus or minus 5.24 vs 26.37 plus or minus 6.85, P = 0.001) and higher social, physical, and material function scores (all P less than 0.001). New pressure injury incidence was lower in the intervention group (3.33 percent vs 26.67 percent, Fisher's exact P = 0.026). Wound improvement or healing did not differ significantly at 1 month (60.00 percent vs 40.00 percent, P = 0.196) but was higher in the intervention group at 3 months (93.33 percent vs 60.00 percent, Fisher's exact P = 0.005). Nursing satisfaction scores were also higher (all P less than 0.001). The authors conclude that IMCHB-based nursing may support sustained pressure injury prevention and wound outcomes, while noting that larger randomized studies are needed.

Key takeaways

Sixty inpatients with a pressure injury or high pressure injury risk were allocated by admission period to routine care or to nursing based on the Interaction Model of Client Health Behavior for 3 months.
New pressure injury incidence was lower with the structured program (3.33 percent vs 26.67 percent, Fisher's exact P = 0.026).
Wound improvement or healing was similar at 1 month (60.00 percent vs 40.00 percent, P = 0.196) but higher with the program at 3 months (93.33 percent vs 60.00 percent, Fisher's exact P = 0.005).
Caregiver knowledge and nursing satisfaction scores were also higher in the intervention group (P = 0.001 and all P less than 0.001).

Why this matters on shift

Preventing pressure injuries and supporting wound healing depend on consistent behaviors from nurses, patients, and caregivers over time, which is hard to sustain with usual care. This study may matter for wound and med-surg nurses because it tests a structured behavior-focused nursing model and links it to fewer new pressure injuries and more healing over 3 months.

Bedside takeaway

Worth knowing that in a small single-center study, a structured behavior-focused nursing program was linked to fewer new pressure injuries and more wound healing at 3 months than routine care alone.

Nursing implications

For nurses caring for patients at pressure injury risk, the findings suggest that a structured program engaging patients and caregivers in prevention behaviors, alongside routine skin and repositioning care, may reinforce pressure injury prevention and wound healing. Because this was a small, single-center, non-randomized study, the model is best viewed as a promising addition to established prevention bundles rather than a proven replacement.

Limitations & cautions

This was a single-center, non-randomized quasi-experimental study of only 60 inpatients, with groups assigned by admission period rather than randomization, so unmeasured differences between the groups could have influenced the results. The 3-month follow-up at one Chinese hospital may not generalize to other settings, and the authors themselves call for larger randomized trials.
