[Lazio dialysis registry: natives vs foreigners]

An increasing number of foreigners was observed in Italy even among chronic dialysis patients. We compared demographic, clinical, treatment characteristics and survival probability between groups of Italian and foreign patients with chronic dialysis in Lazio

Determinants of hospitalization in a cohort of chronic dialysis patients in central Italy

Background: Few studies linking hospital discharge records with the population register of chronic dialysis (CD) patients are available. This study aimed to evaluate the frequency and the determinants of hospitalization, taking into account the demographic, clinical and biochemical data. Methods: We conducted a retrospective cohort study in 3411 patients starting dialysis from 1996-2000, reported to the Lazio Dialysis Registry (RDL) (Italy). These patients were linked with the hospital information system from 1996-2002. Hospital admission probability was calculated using the Kaplan-Meier method. To evaluate the determinants of hospitalization risk we used Cox's proportional hazards for the first admission and a marginal model considering competitive effect of mortality, the Wei-Lin-Weissfeld model, for any admission. Results: We found 7530 hospital admissions, referring to 1711 patients (50.7%), with a rate of 63/100 person-years. The most prevalent diagnoses were "diseases of the genitourinary system", (37.4%), and "diseases of the circulatory system", among secondary diagnoses (46.6%). Hospitalization probability was 34.4% at 1 yr after starting dialysis. The risk of first and any hospital admission was higher (p<0.05) for patients having more than one comorbid disease, hematocrit (Hct) level <30%, serum albumin level <3.5 g/dL, and a low degree of self-sufficiency. Conclusions: Hospitalization frequency, mainly during the first months of dialysis, suggests the need to improve the early management of chronic renal failure and indicates the importance of preventing complications and maximizing functional status among the dialysis population

Risk factors and action thresholds for the novel coronavirus pandemic. Insights from the Italian Society of Nephrology COVID-19 Survey

365noBackground and aim: Over 80% (365/454) of the nation’s centers participated in the Italian Society of Nephrology COVID-19 Survey. Out of 60,441 surveyed patients, 1368 were infected as of April 23rd, 2020. However, center-specific proportions showed substantial heterogeneity. We therefore undertook new analyses to identify explanatory factors, contextual effects, and decision rules for infection containment. Methods: We investigated fixed factors and contextual effects by multilevel modeling. Classification and Regression Tree (CART) analysis was used to develop decision rules. Results: Increased positivity among hemodialysis patients was predicted by center location [incidence rate ratio (IRR) 1.34, 95% confidence interval (CI) 1.20–1.51], positive healthcare workers (IRR 1.09, 95% CI 1.02–1.17), test-all policy (IRR 5.94, 95% CI 3.36–10.45), and infected proportion in the general population (IRR 1.002, 95% CI 1.001–1.003) (all p < 0.01). Conversely, lockdown duration exerted a protective effect (IRR 0.95, 95% CI 0.94–0.98) (p < 0.01). The province-contextual effects accounted for 10% of the total variability. Predictive factors for peritoneal dialysis and transplant cases were center location and infected proportion in the general population. Using recursive partitioning, we identified decision thresholds at general population incidence ≥ 229 per 100,000 and at ≥ 3 positive healthcare workers. Conclusions: Beyond fixed risk factors, shared with the general population, the increased and heterogeneous proportion of positive patients is related to the center’s testing policy, the number of positive patients and healthcare workers, and to contextual effects at the province level. Nephrology centers may adopt simple decision rules to strengthen containment measures timely.nonenoneNordio M.; Reboldi G.; Di Napoli A.; Quintaliani G.; Alberici F.; Postorino M.; Aucella F.; Messa P.; Brunori G.; Brunori G.; Bosco M.; Malberti F.; Mandreoli M.; Mazzaferro S.; Movilli E.; Ravera M.; Salomone M.; Santoro D.; PostorinoLimido M.A.; Bonomini M.; Stingone A.; Maccarone M.; Di Loreto E.; Stacchiotti L.; Malandra R.; Chiarella S.; D'Agostino F.; Fuiano G.; Nicodemo L.; Bonofiglio R.; Greco S.; Mallamaci F.; Barreca E.; Caserta C.; Bruzzese V.; Galati D.; Tramontana D.; Viscione M.; Chiuchiolo L.; Tuccillo S.; Sepe M.; Vitale F.; Ciriana E.; Santoro D.; Martignetti V.; Caserta D.; Stizzo A.; Romano A.; Iulianiello G.; Cascone E.; Minicone P.; Chiricone D.; Delgado G.; Barbato A.; Celentano S.; Molfino I.; Coppola S.; Raiola I.; Abategiovanni M.; Borrelli S.; Margherita C.; Bruno F.; Ida M.; Aliperti E.; Potito D.; Cuomo G.; De Luca M.; Merola M.; Botta C.; Garofalo G.; Alinei P.; Paglionico C.; Roano M.; Vitale S.; Ierardi R.; Fimiani V.; Conte G.; Di Natale G.; Romano M.; Di Marino V.; Scafarto A.; Meccariello S.; Pecoraro C.; Di Stazio E.; Di Meglio E.; Cuomo A.; Maresca B.; Rotaia E.; Capasso G.; Auricchio M.; Pluvio C.; Maddalena L.; De Maio A.; Palladino G.; Buono F.; Gigliotti G.; Mandreoli M.; Mancini E.; La Manna G.; Storari A.; Mosconi G.; Cappelli G.; Scarpioni R.; Gregorini M.; Rigotti A.; Mancini W.; Bianco F.; Boscutti G.; Amici G.; Tosto M.; Fini R.; Pace G.; Cioffi A.; Boccia E.; Di Lullo L.; Di Zazzo G.; Simonelli R.; Bondatti F.; Miglio L.; Rifici N.; Treglia A.; Muci M.; Baldinelli G.; Rizzi E.; Lonzi M.; De Cicco C.; Forte F.; De Paolis P.; Grandaliano G.; Cuzziol C.; Torre V.M.; Sfregola P.; Rossi V.; Fabio G.; Flammini A.; Filippini A.; Onorato L.; Vendola F.; Di Daniela N.; Alfarone C.; Scabbia L.; Ferrazzano M.; Grotta B.D.; Gamberini M.; Fazzari L.; Mene P.; Morgia A.; Catucci A.; Palumbo R.; Puliti M.; Marinelli R.; Polito P.; Marrocco F.; Morabito S.; Rocca R.; Nazzaro L.; Lavini R.; Iamundo V.; Chiappini M.; Casarci M.; Morosetti M.; Hassan S.; Alfarone C.; Ferrazzano M.; Firmi G.; Galliani M.; Serraiocco M.; Feriozzi S.; Valentini W.; Sacco P.; Garibotto G.; Cappelli V.; Saffioti C.; Repetto M.; Rolla D.; Lorenz M.; Pedrini L.; Polonioli D.; Galli E.; Ruggenenti P.; Scolari F.; Bove S.; Costantino E.; Bracchi M.; Mangano S.; Depetri G.; Malberti F.; La Milia V.; Farina M.; Zecchini S.; Savino R.; Melandri M.; Guastoni C.; Paparella M.; Gallieni M.; Minetti E.; Bisegna S.; Messa P.; Righetti M.; Badalamenti S.; Guastoni C.; Alberghini E.; Bertoli S.; Fabbrini P.; Albrizio P.; Rampino T.; Colturi C.; Rombola G.; Lucatello A.; Guerrini E.; Ranghino A.; Lenci F.; Fanciulli E.; Santarelli S.; Damiani C.; Garofalo D.; Sopranzi F.; Santoferrara A.; Di Luca M.; Galiotta P.; Brigante M.; Manganaro M.; Maffei S.; Berto I.; Besso L.; Viglino G.; Besso L.; Cusinato S.; ChiarinottiChiappero D.F.; Tognarelli G.; Gianoglio B.; Salomone M.; Forneris G.; Biancone L.; Savoldi S.; Vitale C.; Boero R.; Filiberti O.; Borzumati M.; Gesualdo L.; Lomonte C.; Gernone G.; Pallotta G.; Di Paolo S.; Vernaglione L.; Specchio A.; Stallone G.; Dell'Aquila R.; Aucella F.; Sandri G.; Russo F.; Napoli M.; Marangi A.; Morrone L.; Di Stratis C.; Fresu A.; Cicu F.; Murtas S.; Manca O.; Pani A.; Pilloni M.; Pistis R.; Cadoni M.; Contu B.; Logias F.; Ivaldi R.; Fancello S.; Cossu M.; Lepori G.; Lepori G.; Vittoria S.; Battiati E.; Arnone M.; Rome M.; Barbera A.; Granata A.; Collura G.; Dico C.L.; Pugliese G.; Di Natale E.; Rizzari G.; Cottone L.; Longo N.; Battaglia G.; Marcantoni C.; Giannetto G.; Tumino G.; Randazzo F.; Bellissimo L.; Faro F.L.; Grippaldi F.; Urso S.; Quattrone G.; Todaro I.; Vincenzo D.; Murgo A.; Masuzzo M.; Pisacane A.; Monardo P.; Santoro D.; Pontorierro M.; Quari C.; Bauro A.; Chimenz R.R.; Alfio D.; Girasole F.; Cascio A.L.; Caviglia A.; Tornese F.; Sirna F.; Altieri C.; Cusumano R.; Saveriano V.; La Corte A.; Locascio G.; Rotolo U.; Rome M.; Musso S.; Risuglia L.; Blanco G.; Minardo G.; Castellino S.; Zappulla Z.; Randone S.; Di Francesca M.; Cassetti C.C.; Oddo G.; Buscaino G.; Mucaria F.; Barraco V.I.; Di Martino A.; Mucaria F.; Rallo D.; Dani L.; Campolo G.; Manescalchi F.; Biagini M.; Agate M.; Panichi V.; Casani A.; Traversari L.; Garosi G.; Brunori G.; Tabbi M.; Selvi A.; Cencioni L.; Fagugli R.; Timio F.; Leveque A.; Manes M.; Mennella G.; Calo L.; Fiorini F.; Abaterusso C.; Calzavara P.; Nordio M.; Meneghel G.; Bonesso C.; Gambaro G.; Gammaro L.; Rugiu C.; Dell'Aquila R.; Dell'Aquila R.; Ronco C.; Rugiu C.Nordio, M.; Reboldi, G.; Di Napoli, A.; Quintaliani, G.; Alberici, F.; Postorino, M.; Aucella, F.; Messa, P.; Brunori, G.; Brunori, G.; Bosco, M.; Malberti, F.; Mandreoli, M.; Mazzaferro, S.; Movilli, E.; Ravera, M.; Salomone, M.; Santoro, D.; Postorinolimido, M.

Risk factors and action thresholds for the novel coronavirus pandemic. Insights from the Italian Society of Nephrology COVID-19 Survey

Background and aim: Over 80% (365/454) of the nation’s centers participated in the Italian Society of Nephrology COVID-19 Survey. Out of 60,441 surveyed patients, 1368 were infected as of April 23rd, 2020. However, center-specific proportions showed substantial heterogeneity. We therefore undertook new analyses to identify explanatory factors, contextual effects, and decision rules for infection containment. Methods: We investigated fixed factors and contextual effects by multilevel modeling. Classification and Regression Tree (CART) analysis was used to develop decision rules. Results: Increased positivity among hemodialysis patients was predicted by center location [incidence rate ratio (IRR) 1.34, 95% confidence interval (CI) 1.20–1.51], positive healthcare workers (IRR 1.09, 95% CI 1.02–1.17), test-all policy (IRR 5.94, 95% CI 3.36–10.45), and infected proportion in the general population (IRR 1.002, 95% CI 1.001–1.003) (all p &lt; 0.01). Conversely, lockdown duration exerted a protective effect (IRR 0.95, 95% CI 0.94–0.98) (p &lt; 0.01). The province-contextual effects accounted for 10% of the total variability. Predictive factors for peritoneal dialysis and transplant cases were center location and infected proportion in the general population. Using recursive partitioning, we identified decision thresholds at general population incidence ≥ 229 per 100,000 and at ≥ 3 positive healthcare workers. Conclusions: Beyond fixed risk factors, shared with the general population, the increased and heterogeneous proportion of positive patients is related to the center’s testing policy, the number of positive patients and healthcare workers, and to contextual effects at the province level. Nephrology centers may adopt simple decision rules to strengthen containment measures timely
