This study retrospectively analyzes all consecutive patients who underwent during a year hospital readmissions, defined as an admission to a hospital within 30 days of discharge, to an Italian Internal Medicine ward. All these data were compared with those from patients who underwent only 1 hospital admission in the same period. The aim of this study was to identify potential novel risk factors for hospital readmissions. In 2018, a total of 3012 patients were hospitalized. Among these, 14.1% (n = 426; mean age, 79.7 ± 11.9; range, 23-100) were defined as readmissions; data were compared with controls (n = 420; 13.9%; mean age, 75.9 ± 14.7; range, 22-99) who had only 1 hospitalization. Cases showed a significantly higher prevalence than controls regarding cerebrovascular disease (77.2% vs 48.1%), cognitive impairment (51.8% vs 26.9%), congestive heart failure (47.6% vs 20.2%), chronic kidney disease (31.7% vs 13.1%), and chronic obstructive pulmonary disease (23.0% vs 14.5%). Skin ulcers were significantly more prevalent among cases (45.1% vs 17.6%). Diagnosis-related group (DRG) analysis showed a higher proportion of “infectious disease” (24.4% vs 15.0%) among the cases than in controls. Despite skin ulcers were very frequent among cases and controls (45.1% vs 17.6%), they were codified as “skin wound” DRG only in 1.4% and 0.2%, respectively. At the DRGs analysis, sepsis (31.6% vs 19.1%), pneumonia (17.1% vs 7.6%), and kidney failure (9.6% vs 3.8%) represented the main significant cause of death in cases compared to controls. Our study confirms that readmissions to Internal Medicine departments are related to the severity of chronic diseases affecting patients. Skin ulcers are present in about half of patients who will be early readmitted within 30 days, but they are almost never reported in DRGs, so more accurate coding is needed. Key challenges for the future are sepsis prevention measures and investing resources in chronic disease assistance, including skin ulcer chronic management.

Purpose: Primary meningococcal arthritis (PMA) represents an uncommon clinical presentation of meningococcal infection, mainly reported among young people. Herein, a case of PMA of the knee in an elderly patient is described.Case presentation: On January 2022, an 87-year-old patient arrived at hospital with continuous fever persisting for three days and a picture of joint pain, swelling, redness, and warmth of her left knee. An arthrocentesis was promptly performed and the inoculated synovial uid turned positive with numerous Gram-negative diplococci at the microscopic examination. The BioFire® FilmArray®Meningitis/Encephalitis (ME) Panel (bioMérieux) quickly con rmed the presence of Neisseria meningitidis. The meningococcal isolate belonged to the serogroup B (MenB), Sequence type (ST)-162/ clonal complex (cc)162.Two grams of ceftriaxone twice a day were administered for 21 days; than cefditoren pivoxil 400 mg twice a day for further 6 weeks after discharge.

Real-life outcomes data for elderly patients with infections caused by Klebsiella pneumoniae producing New Delhi metallo-beta-lactamase (NDM-Kp) are lacking. We conducted a retrospective cohort study enrolling 33 consecutive adult patients (mean age 77.4 years; 48.5% males; mean Charlson Comorbidity Index-CCI 5.9) hospitalized for NDM-Kp infections during a 24 months period in an Italian highly endemic area. 78.8% were admitted to Internal Medicine ward. 45.4% of patients had bloodstream infections (BSI), 39.4% urinary tract infections (UTI) without BSI, 9.1% respiratory tract infections and 6.1% intra-abdominal infections. 93.9% had rectal colonization. Adequate definitive antibiotic therapy (mainly represented by aztreonam plus ceftazidime/avibactam) was provided to 36.4% of cases. Mean age and CCI of patients adequately treated were significantly lower than those inadequately treated (71.2 vs 80.9 years, p = 0.041, and 4.6 vs 6.7, p = 0.040, respectively). Patients adequately treated had a mean hospitalization length significantly higher (28 vs 15 days, p = 0.016). The overall 30 day-survival rate of patients adequately and inadequately treated was 83.3% and 57.1%, respectively: this difference was not statistically significant. Mean age and CCI of 22 patients who survived at 30 days were lower than those of 11 patients who died (73.7 vs 84.8 years, p = 0.003, and 5.3 vs 7.2, p = 0.049, respectively). Twelve survivors received an inadequate therapy: 8/12 had UTI. Six of 9 patients inadequately treated who died within 30 days, died before microbiological diagnosis. Our study provides real-life data on outcomes of elderly and multimorbid patients hospitalized for infections caused by NDM-Kp. Further studies with larger sample size are warranted.
