Elderly Outcomes After Hospitalization: The Hospital Frailty Risk Score Applied on the French Health Data Hub.

Objectives: To demonstrate the association between the Hospital Frailty Risk Score (HFRS) and 30-day mortality, 30-day hospital readmission and length of stay (LOS) in France. Methods: Logistic regressions were performed using data recorded in the French national health data system (SNDS) for elderly patients (≥75 years old) hospitalized in France in 2017. Results: Over the 1,111,090 patients included, 30-day mortality was associated with the HFRS: adjusted OR (aOR) for an intermediate HFRS (5-15 points) was 1.91 [95% confidence interval (95% IC); 1.87-1.95] and aOR 2.57 [95% IC; 2.50-2.64] for high HFRS (>15 points), as compared to low HFRS (<5 points). LOS >10 days increased with the HFRS (aOR = 1.36 [95% IC; 1.34-1.38] for an intermediate HFRS and aOR 1.51 [95% IC; 1.48-1.54] for a high HFRS). A high HFRS was associated with 30-day hospital readmission (aOR = 1.06 [95% IC; 1.04-1.08]). Discussion: This real-life analysis of in- and out-patient healthcare pathways confirmed the HFRS's ability to predict adverse outcomes, after adjustment on social deprivation.

Impact of a phone call with a medical student/general practitioner team on morbidity of chronic patients during the first French COVID-19 lockdown (COVIQuest): a cluster randomised trial.

OBJECTIVES: The first COVID-19 lockdown led to a significantly reduced access to healthcare, which may have increased decompensations in frail patients with chronic diseases, especially older patients living with a chronic cardiovascular disease (CVD) or a mental health disorder (MHD). The objective of COVIQuest was to evaluate whether a general practitioner (GP)-initiated phone call to patients with CVD and MHD during the COVID-19 lockdown could reduce the number of hospitalisation(s) over a 1-month period. DESIGN: This is a cluster randomised controlled trial. Clusters were GPs from eight French regions. PARTICIPANTS: Patients ≥70 years old with chronic CVD (COVIQuest_CV subtrial) or ≥18 years old with MHD (COVIQuest_MH subtrial). INTERVENTIONS: A standardised GP-initiated phone call aiming to evaluate patients' need for urgent healthcare, with a control group benefiting from usual care (ie, the contact with the GP was by the patient's initiative). MAIN OUTCOME MEASURES: Hospital admission within 1 month after the phone call. RESULTS: In the COVIQuest_CV subtrial, 131 GPs and 1834 patients were included in the intervention group and 136 GPs and 1510 patients were allocated to the control group. Overall, 65 (3.54%) patients were hospitalised in the intervention group vs 69 (4.57%) in the control group (OR 0.82, 95% CI 0.56 to 1.20; risk difference -0.77, 95% CI -2.28 to 0.74). In the COVIQuest_MH subtrial, 136 GPs and 832 patients were included in the intervention group and 131 GPs and 548 patients were allocated to the control group. Overall, 27 (3.25%) patients were hospitalised in the intervention group vs 12 (2.19%) in the control group (OR 1.52, 95% CI 0.82 to 2.81; risk difference 1.38, 95% CI 0.06 to 2.70). CONCLUSION: A GP-initiated phone call may have been associated with more hospitalisations within 1 month for patients with MHD, but results lack robustness and significance depending on the statistical approach used.

HIV surveillance combining an assay for identification of very recent infection and phylogenetic analyses on dried spots.

BACKGROUND: Transmitted/founder viruses isolated at the early stage of infection are indicators of the variants that are spreading within a population. The French reporting system for new HIV diagnoses is linked to a virological surveillance using dried serum spots. METHODS: We combined an immunoassay for very recent infection (less than 31 days) to a phylogenetic analysis of transmitted/founder viruses and sociodemographic information to analyze the dynamics of the HIV-1 epidemic during a 3-year period. Bayesian coalescent-based methods were used to explore the temporal and spatial dynamics of the identified clusters. RESULTS: Of 17 010 dried serum spots collected, 549 very recent infections were identified for which both env sequences and sociodemographic data were available. Non-B transmitted/founder viruses were found in 196 cases (35.7%), belonging to six subtypes and seven circulating recombinant forms. Forty-three dyads/clusters were identified (range 2-11 cases), including 107 individuals (19.5%), mainly MSM. The largest cluster involved MSM infected by a CRF02_AG variant. Reconstruction of viral migrations across time suggests that Paris was the major hub of dissemination. CONCLUSION: The study shows the feasibility of the surveillance of the HIV epidemic using this methodology. The observation of actively growing spatiotemporal clusters allows identification of specific networks that may be targets for intervention.

[Infectious spondylodiscitis]. / Spondylodiscites infectieuses.

Vertebral osteomyelitis (VO) is an infection of the intervertebral disc with a possible extension to adjacent vertebrae. Annual incidence of VO in France is 2.4/100,000 inhabitants. It increases with age, above 6/100,000 over 70 years old. Eighty percent are hematogenous, and 20% developed after spinal surgery. The main unspecific symptoms are inflammatory spine pain, associated or not with fever. Diagnosis is performed with MRI, then blood cultures and disco-vertebral biopsy. The main causative organisms are staphylococci (40 to 60%), even though tuberculosis can be observed in 20%. Specific antimicrobial therapy, immobilisation and reeducation are needed. Clinical practice guidelines for management of infectious spondylodiscitis have been edited in 2007.
