Predictors of Prolonged Hospitalization and In-Hospital Mortality After Hip Fracture: A Retrospective Study on Discharge Registry.

Background: Hip fracture injury is one of the principal health problems affecting the elderly. Patients reporting hip fractures often show relevant comorbidities leading to prolonged hospital stay, significant complications and higher mortality rates. This study aims to assess the risk factors associated with prolonged hospitalization after hip fracture, in-hospital mortality and transfers to other facilities. Study design: Retrospective cross-sectional study. Methods: The study considered all admissions performed between 2006 and 2015 in Abruzzo region, Italy. Logistic regression analyses were performed to evaluate odds ratios for each risk factor as predictor of in-hospital mortality, length of stay, and transfer to other facilities. Results: Age over 85 (OR=5.38) and cancer (OR=3.62) were identified as the strongest risk predictors for in hospital mortality; diabetes (OR=2.24) and heart failure (OR=1.57) were identified as predictors of prolonged length of stay and age over 85 (OR=1.38) and atrial fibrillation (OR=1.69) were identified as predictors of transfer to other facilities. Conclusions: With the rising incidence of hip fractures, identification of modifiable factors may help to reduce morbidity and mortality.

The Revolving Door Phenomenon: Psychiatric Hospitalization and Risk of Readmission Among Drug-Addicted Patients.

BACKGROUND: Substance use may influence the onset and course of psychiatric diseases. The "Revolving door" (RD) phenomenon, which indicates repeated hospitalizations of the same patients, has become a public health. OBJECTIVES: The aim of this study was detecting the risk factors associated to hospital readmission to psychiatric wards of drug-addicted patients. METHODS: The study considered all the admissions performed between 2006 and 2015 in Abruzzo, Italy. Only the hospital discharge registry having code 304 (drug dependence) as diagnosis was taken into account. In addition, only the patients with a psychiatric DRG were included. RESULT: 325 patients performed 558 psychiatric admissions during the study period (1089 person-years). The analyses of the discharge registry showed "Psychoses" as the main DRG (73.2%). An amount of 119 patients experienced a second psychiatric admission. Psychiatric readmissions were independently predicted by Schizofrenia (HR=2.061) and Anxiety disorders (HR=0.326). CONCLUSION: Psychiatric hospitalization and readmission are frequent among drug-addicted patients. The subsequent RD phenomenon has become a public health issue, both for health and economic sides.

Trend in Hospital Admissions of Drug Addicts and Associated Factors from 2006 to 2015: an Observational Study on the Hospitals' Discharge Registries from a Region of Central Italy.

BACKGROUND: Several social, economic and political factors have contributed to the global spread of alcohol and other drugs. Drug addiction represents a huge expense for the society in terms of direct and indirect health and social consequences, as it is associated with numerous medical issues such as HIV, other infections and psychiatric disturbances. OBJECTIVES: The aim of this study was the assessment of the hospital admissions among drug addicted patients in Abruzzo Region, central Italy, from 2006 to 2015, in order to clarify the specific causes of hospitalization. METHODS: Data were collected from all hospital discharge records, taking into account only the hospital discharge registrations coded 304 (drug dependence). Multivariate logistic regression was performed to evaluate factors associated with main causes of the admission. RESULTS: Between 2006 and 2015, an amount of 2,159 drug-addicted subjects, aged 38.0±9.7 years, were admitted to hospital. Most of the admissions occurred in public hospitals (2,039, 94.4%), through the emergency room access (1,503, 69.6%) From an amount of 2,159 hospitalizations, 1,178 (54.6%) were first and 981 (45.4%) were subsequent admissions. The most frequent cause of hospitalization was "Psychosis" (419, 19.4%). The trend by range of age showed a progressive reduction in hospital admissions for patients aged < 45 y. Further, an increase in the hospitalization rate was estimated over recent years among drug addict subjects aged 25-45 years. Cannabis consumption was associated with mental disorder admissions (OR: 3.16, p<0.001), opioid consumption was associated with hepatic disorder admission (OR:2.16, p<0.001) and cardiovascular admissions (OR: 1,78, p<0.001), and cocaine was associated with cardiovascular admissions (OR:1,55, p:<0.001). CONCLUSIONS: Mental disorders result to be the leading cause of hospitalization among drug-addicts, principally associated with cannabis abuse. Opioid and cocaine abuse was associated with hepatic and cardiovascular disorders.

Reproducibility of rectal tumor volume delineation using diffusion-weighted MRI: Agreement on volumes between observers.

PURPOSE: To retrospectively evaluate the inter-observer agreement between a radiologist and a radiation oncologist and volume differences, in T2 and diffusion-weighted (DWI) MRI of gross tumor volume (GTV) delineation, in rectal cancer patients. MATERIALS AND METHODS: Two observers, a radiologist and a radiation oncologist, delineated GTVs of 50 patients on T2-weighted MRI (T2GTV) and echo planar DWI (DWIGTV). Observers agreement was assessed using DICE index, Bland-Altman analysis and intra-class correlation coefficient (ICC). Student's t-test was used for GTV comparison. RESULTS: Median T2GTV and DWIGTV were 17.09±14.12 cm3 (1.92-62.03) and 12.79±12.31 cm3 (1.23-62.25) for radiologist, and 16.82±13.66 cm3 (1.78-65.9) and 13.72±12.77 cm3 (1.29-69.75) for radiation oncologist. T2GTV were significantly larger compared to DWIGTV (P<0.001 and P<0.001, for both observers). Mean DICE index for T2GTV and DWIGTV were 0.80±0.07 and 0.77±0.06. The mean difference between the two observers were 0.26cm3 (95% CI: -5.36 to 5.88) and -1.13cm3 (95% CI: -5.70 to 3.44) for T2 and DWI volumes. The ICC for T2 volumes was 0.989 (95% CI: 0.981-0.994) (P<0.001) and 0.992 (95% CI: 0.986-0.996) (P<0.001) for DWI volumes. CONCLUSION: DWI resulted in smaller volumes delineation compared to T2-weighted MRI. Substantial and almost perfect agreements were reported for DWIGTV and T2GTV between radiologist and radiation oncologist. Due to the fact that DWI could be considered a simple technique for volume delineation for radiation oncologist, DWI could be used to improve quality in radiation planning for an accurate boost volume delineation when a dose escalation is investigated.
