Validation of the ICEBERG emergency room screening tool for early identification of older patients with geriatric consultation needs.

Background: The growing number of older and oldest-old patients often present in the emergency room (ER) with undiagnosed geriatric syndromes posing them at high risk for complications in acute care. Objective: To develop and validate an ER screening tool (ICEBERG) to capture 9 geriatric domains of risk in older patients. Design setting and participants: For construct validity we performed a chart-based study in 129 ER patients age 70 years and older admitted to acute geriatric care (pilot 1). For criterion validity we performed a prospective study in 288 ER patients age 70 years and older admitted to acute care (pilot 2). Exposure: In both validation steps, the exposure was ICEBERG test performance below and above the median score (10, range 0-30). Outcome measures and analysis: In pilot 1, we compared the exposure with results of nine tests of the Comprehensive Geriatric Assessment (CGA). In pilot 2, we compared the exposure assessed in the ER to following length of hospital stay (LOS), one-on-one nursing care needs, in-hospital mortality, 30-day re-admission rate, and discharge to a nursing home. Main results: Mean age was 82.9 years (SD 6.7; n = 129) in pilot 1, and 81.5 years (SD 7.0; n = 288) in pilot 2. In pilot 1, scoring ≥10 was associated with significantly worse performance in 8 of 9 of the individual CGA tests. In pilot 2, scoring ≥10 resulted in longer average LOS (median 7 days, IQR 4, 11 vs. 6 days, IQR 3, 8) and higher nursing care needs (median 1,838 min, IQR 901, 4,267 vs. median 1,393 min, IQR 743, 2,390). Scoring ≥10 also increased the odds of one-on-one nursing care 2.9-fold (OR 2.86, 95%CI 1.17-6.98), and the odds of discharge to a nursing home 3.7-fold (OR 3.70, 95%CI 1.74-7.85). Further, scoring ≥10 was associated with higher in-hospital mortality and re-hospitalization rates, however not reaching statistical significance. Average time to complete the ICEBERG tool was 4.3 min (SD 1.3). Conclusion: Our validation studies support construct validity of the ICEBERG tool with the CGA, and criterion validity with several clinical indicators in acute care.

Zinc Oxide Patches Are a Highly Effective Treatment for Chronic Prurigo: A Randomized Split-Body Study.

BACKGROUND: Chronic prurigo (CPG) presents with pruriginous lesions and reduced quality of life (QoL). Established treatment options are often unsatisfying. Little is known about the efficacy of topical occlusive treatments. Patients often report rapid relief of symptoms when using topical occlusive zinc oxide patches (ZOP). We, therefore, aimed to assess the efficacy of ZOP. METHODS: In this randomized controlled split-body crossover study, 22 participants were analyzed, receiving three treatments sequentially: ZOP, topical betamethasone 17-valerate (topical glucocorticosteroids [TGCs]), and both ZOP and TGC combined (ZOP + TGC). Each intervention was applied to either the right or left side of the body for seven consecutive days. Outcomes were a count of active excoriated pruriginous lesions (APLs), itch, recurrence of APL, QoL, and treatment comfort. They were assessed through photographs and questionnaires: modified Prurigo Activity and Severity Score, modified Itchy Quality of Life Questionnaire, and Therapy Comfort Score. RESULTS: We observed a significant reduction of 46% in APL count for ZOP (95% CI from 30% to 58%, p value: <0.0001). Similar reduction was seen for ZOP + TGC, and a lower reduction was seen for TGC alone (48% [95% CI from 33% to 60%, p value: <0.0001] vs. 26% [95% CI from 4% to 43%, p value: 0.02]). APL counts on the non-treated side remained stable. Significant reduction in itch was observed after all treatments, with the largest improvement for ZOP + TGC, followed by TGC and, lastly, ZOP alone (-2.3 units [95% CI from -3.5 to -1.1, p value: 0.00015] vs. -1.5 units [95% CI from -2.8 to -0.3, p value: 0.01 vs. -1.4 units [95% CI from -2.6 to -0.2, p value: 0.02]). QoL increased significantly after ZOP + TGC as well as after TGC (-8.3 units [95% CI from -13.6 to -3.1, p value: 0.0018] vs. -5.7 units [95% CI from -10.9 to -0.5, p value: 0.03]). A good subjective response concerning treatment comfort was observed. CONCLUSION: ZOP are effective in reducing APL after 1 week of treatment. Adding TGC to ZOP did not add considerable benefit in reducing APL. All three treatments reduced itch and improved QoL, with the largest improvement shown by ZOP combined with TGC. Patients tolerated ZOP well and reported no adverse events. We therefore suggest ZOP combined with TGC as an effective, fast-acting, low-cost treatment for reducing APL and itch in patients with CPG.

Dupilumab for Chronic Prurigo: Case Series on Effectiveness, Safety, and Quality of Life.

BACKGROUND: Chronic prurigo (CPG) is a pruritic skin disease, characterized by an itch-scratch cycle and scarring. It reduces patients' quality of life (QoL). Dupilumab is a monoclonal human IgG antibody that inhibits signaling of the interleukin 4 (IL-4) and interleukin 13 (IL-13) pathways through blockade of the IL-4 receptor. Patients with CPG who receive dupilumab often report great improvement in itch and overall QoL. We therefore reviewed our experience in order to follow up on QoL, safety, and treatment response in patients with CPG who received dupilumab. METHODS: We conducted a real-world retrospective single-center case series. Outcomes were assessed by phone interviews and photographs using validated questionnaires and scores. Demographic data were obtained from the hospital files. Follow-up was up to 2 years. We assessed QoL with the Dermatology Life Quality Index (DLQI) and the Itchy quality of life questionnaire (ItchyQoL). Numerical Rating Scale (NRS) was used to assess itch. Prurigo lesions were documented with the Prurigo activity and severity score (PAS). RESULTS: Ten patients were included in this study. Results were reported up to 2 years after treatment with dupilumab. The response variables for DLQI, ItchyQoL, NRS, and PAS analyses showed a statistically significant decrease over time (DLQI: p ≤ 0.0001 [-0.84; -1.27], ItchyQoL: p ≤ 0.0001 [-9.89; -18.69], NRS maximum and average: p ≤ 0.0001 [-0.52; -0.86] and p ≤ 0.0001 [-0.55; -0.94], and PAS number of lesions: p = 0.0005 [-1.70; -5.28]). The percent decrease after 1 year of treatment (this estimate is based on model estimates) ranges from -42% to -82%. Four (40%) patients reported mild side effects. No serious side effects were reported. CONCLUSION: Dupilumab treatment of CGP for up to 2 years is associated with improved QoL and less itching.
