Measuring multimorbidity inequality across Italy through the multisource comorbidity score: a nationwide study.

BACKGROUND: Multimorbidity is a growing concern for healthcare systems, with many countries experiencing demographic transition to older population profiles. A simple multisource comorbidity score (MCS) has been recently developed and validated. A very large real-world investigation was conducted with the aim of measuring inequalities in the MCS distribution across Italy. METHODS: Beneficiaries of the Italian National Health Service aged 50-85 years who in 2018 were resident in one of the 10 participant regions formed the study population (15.7 million of the 24.9 million overall resident in Italy). MCS was assigned to each beneficiary by categorizing the individual sum of the comorbid values (i.e. the weights corresponding to the comorbid conditions of which the individual suffered) into one of the six categories denoting a progressive worsening comorbidity status. MCS distributions in women and men across geographic partitions were compared. RESULTS: Compared with beneficiaries from northern Italy, those from centre and south showed worse comorbidity profile for both women and men. MCS median age (i.e. the age above which half of the beneficiaries suffered at least one comorbidity) ranged from 60 (centre and south) to 68 years (north) in women and from 63 (centre and south) to 68 years (north) in men. The percentage of comorbid population was lower than 50% for northern population, whereas it was around 60% for central and southern ones. CONCLUSION: MCS allowed of capturing geographic variability of multimorbidity prevalence, thus showing up its value for addressing health policy in order to guide national health planning.

[Individual and health care factors, and one-year hospital readmission of elderly patients in Friuli Venezia Giulia, Northeastern Italy]. / Fattori individuali e legati all'assistenza associati ai ricoveri ripetuti entro un anno da un precedente ricovero nella popolazione anziana del Friuli Venezia Giulia.

OBJECTIVE: we investigated both individual and health care risk factors for one-year readmissions of medical patients in the Friuli Venezia Giulia Region, Northeastern Italy. DESIGN: we conducted a retrospective cohort study based on administrative databases. SETTING AND PARTICIPANTS: the cohort was made of all the patients who were admitted for any cause to non surgical wards of any regional or extraregional hospital and discharged from 01.01.2008 to 31.12.2009, excluding one-day stays, and who were 65 years of age, residing in Friuli Venezia Giulia upon admission, and still alive one year after discharge. MAIN OUTCOME MEASURES: we measured the frequency of one-year readmission or death and identified patient-level risk factors and Health Districts and Hospitals performing differently from the average. Multivariable logistic regression was used, accounting for data clustering. RESULTS: over 30% of the patients who were still alive one year after the index discharge were readmitted to hospital. Individual risk factors include age, comorbidity, cause of the index admission. Furthermore, being admitted to nursing homes or hospice after discharge is associated with increased risk of readmission. We identified an area of the region where five Districts performed worse than the average. CONCLUSION: we identified groups of the elderly population at high risk of poor outcomes after hospital discharge and a source of possible disparity in post-discharge health care in the Friuli Venezia Giulia region. These results are the starting point for further inquiries and for improvement of the regional systems of health care delivery.
