External validation of the Hospital Frailty Risk Score in France

Gilbert T, Cordier Q, Polazzi S, Bonnefoy M, Keeble E, Street A, Conroy S, Duclos A.

Abstract:

Background: The Hospital Frailty Risk Score (HFRS) has made it possible internationally to identify subgroups of patients with characteristics of frailty from routinely collected hospital data.

Objective: To externally validate the HFRS in France.

Design: A retrospective analysis of the French medical information database.

Setting: 743 hospitals in Metropolitan France.

Subjects: All patients aged 75 years or older hospitalised as an emergency in 2017 (n = 1,042,234).

Methods: The HFRS was calculated for each patient based on the index stay and hospitalisations over the preceding 2 years. Main outcome measures were 30-day in-patient mortality, length of stay (LOS) >10 days and 30-day readmissions. Mixed logistic regression models were used to investigate the association between outcomes and HFRS score.

Results: Patients with high HFRS risk were associated with increased risk of mortality and prolonged LOS (adjusted odds ratio [aOR] = 1.38 [1.35-1.42] and 3.27 [3.22-3.32], c-statistics = 0.676 and 0.684, respectively), while it appeared less predictive of readmissions (aOR = 1.00 [0.98-1.02], c-statistic = 0.600). Model calibration was excellent. Restricting the score to data prior to index admission reduced discrimination of HFRS substantially.

Conclusions: HFRS can be used in France to determine risks of 30-day in-patient mortality and prolonged LOS, but not 30-day readmissions.

Palliative and high-intensity end-of-life care in schizophrenia patients with lung cancer: results from a French national population-based study

Viprey M, Pauly V, Salas S, Baumstarck K, Orleans V, Llorca PM, Lancon C, Auquier P, Boyer L, Fond G.

Abstract:

Schizophrenia is marked by inequities in cancer treatment and associated with high smoking rates. Lung cancer patients with schizophrenia may thus be at risk of receiving poorer end-of-life care compared to those without mental disorder. The objective was to compare end-of-life care delivered to patients with schizophrenia and lung cancer with patients without severe mental disorder. This population-based cohort study included all patients aged 15 and older who died from their terminal lung cancer in hospital in France (2014-2016). Schizophrenia patients and controls without severe mental disorder were selected and indicators of palliative care and high-intensity end-of-life care were compared. Multivariable generalized log-linear models were performed, adjusted for sex, age, year of death, social deprivation, time between cancer diagnosis and death, metastases, comorbidity, smoking addiction and hospital category. The analysis included 633 schizophrenia patients and 66,469 controls. The schizophrenia patients died 6 years earlier, had almost twice more frequently smoking addiction (38.1%), had more frequently chronic pulmonary disease (32.5%) and a shorter duration from cancer diagnosis to death. In multivariate analysis, they were found to have more and earlier palliative care (adjusted Odds Ratio 1.27 [1.03;1.56]; p = 0.04), and less high-intensity end-of-life care (e.g., chemotherapy 0.53 [0.41;0.70]; p < 0.0001; surgery 0.73 [0.59;0.90]; p < 0.01) than controls. Although the use and/or continuation of high-intensity end-of-life care is less important in schizophrenia patients with lung cancer, some findings suggest a loss of chance. Future studies should explore the expectations of patients with schizophrenia and lung cancer to define the optimal end-of-life care.

Impact of a Digital Cognitive Aid on the Performance of Military Healthcare Teams During Critical Care Management in a Warfront Injury Situation: A Simulation Randomized Controlled Study

Paraschiv AP, Cejka JC, Lilot M, Aigle L, Lehot JJ, Balança B.

Abstract:

Introduction: Initial healthcare delivery after warfront injury is unpredictably challenging for military forces. As preparatory training, healthcare providers use simulation to improve their performance in stressful critical situations. This study investigated whether a digital CA held by the team leader improved performance in simulated combat casualty care.

Methods: This randomized controlled trial was performed during a combat casualty training course for military physicians and nurses in France. Each pair of care providers completed 2 scenarios randomized to be undertaken either with or without a digital CA. The primary end point was the technical performance evaluated from a video recording by 2 independent raters using a pre-established score grid (up to 100%) according to military protocols. The secondary end point was the nontechnical performance (TEAM scale, maximum: 54 points).

Results: Thirty-six pairs of participants were included. Use of the digital CA improved both technical (74% vs 53%, P < 0.001) and nontechnical (42 vs 32, P < 0.001) performance.

Conclusions: The digital CA improved technical and nontechnical performance during training of medical care for military combat casualties. Use of a dedicated digital CA might improve care in a combat environment.

Hypoparathyroidism: Consequences, economic impact, and perspectives. A case series and systematic review

Fanget F, Demarchi MS, Maillard L, El Boukili I, Gerard M, Decaussin M, Borson-Chazot F, Lifante JC.

Abstract:

Background: Postoperative hypoparathyroidism (PH) is the most common complication after total thyroidectomy. Incidence varies from 2% to 83%, depending on the definition.

Objective: We performed a systematic review of the literature to determine the medico-economic effects of PH and update understanding of long-term consequences, morbidity, and quality of life related to hypoparathyroidism.

Methods: We considered relevant articles published between 2000 and 2020 concerning long-term consequences of PH and quality of life. All studies concerning the medico-economic assessment of PH were included. We compared data from 2018 to results in the literature.

Results: A proportion of 64/403 (16.8%) patients presented with transient PH during 2018, and 7/403 (1.7%) had permanent PH. Seven patients needed supplementation with alfacalcidol at 6-month follow-up. Factors predicting the need for alfacalcidol were age <45, thyroidectomy for goiter, and lymph node dissection. Additional therapy costs related to PH were €9781.10, and additional hospital costs were €230,400. We qualitatively synthesized 41 studies. Most were retrospective studies and only a few reported costs. No series assessed direct or indirect costs of postoperative PH.

Conclusion: To our knowledge, no previous studies reported the medico-economic impact of PH. Decreasing PH associated with fluorescence usage should be considered, particularly concerning cost-effectiveness.
