Prophylactic or therapeutic doses of heparins for COVID-19 infection? A retrospective study.

BACKGROUND: Coronavirus disease 19 (COVID-19) is a global outbreak. COVID-19 patients seem to have relevant coagulative abnormalities, even if they are not typical of disseminated intravascular coagulopathy (DIC) of the kind seen in septicaemia. Therefore, anticoagulant therapy with heparins is increasing in interest for a clinical approach to these patients, particularly if older. Studies comparing if prophylactic doses are more effective than therapeutic ones are still missing. METHODS: Data were collected in the Geriatric Section of the Dolo Hospital, ULSS 3 "Serenissima", Venice from 31st March to 01st May 2020. Heparins (calciparin, fondaparinux, enoxaparine) were divided into prophylactic or therapeutic doses. People previously treated with oral anticoagulants were removed. Vital status was assessed using administrative data. Cox's regression analysis, adjusted for potential confounders, was used for assessing the strength of the association between heparins and mortality. The data were reported as hazard ratio (HR) with 95% confidence intervals (CIs). RESULTS: 81 older people (mean age 84.1 years; females = 61.9%) were included. No significant differences in terms of demographic and clinical characteristics emerged between people treated with prophylactic or therapeutic doses, including age, gender, X-rays findings or severity of disease. Therapeutic doses were not associated to a better survival rate (HR 1.06; 95% CI 0.47-2.60; p = 0.89), even after adjusting for 15 confounders related to mortality (HR 0.89; 95% CI 0.30-2.71; p = 0.84). CONCLUSIONS: Our paper indicates that in older people affected by COVID-19 there is no justification for using therapeutic doses instead of prophylactic ones, having a similar impact on mortality risk.

A predictive model to allocate frequent service users of community-based mental health services to different packages of care.

AIM: To develop predictive models to allocate patients into frequent and low service users groups within the Italian Community-based Mental Health Services (CMHSs). To allocate frequent users to different packages of care, identifying the costs of these packages. METHODS: Socio-demographic and clinical data and GAF scores at baseline were collected for 1250 users attending five CMHSs. All psychiatric contacts made by these patients during six months were recorded. A logistic regression identified frequent service users predictive variables. Multinomial logistic regression identified variables able to predict the most appropriate package of care. A cost function was utilised to estimate costs. RESULTS: Frequent service users were 49%, using nearly 90% of all contacts. The model classified correctly 80% of users in the frequent and low users groups. Three packages of care were identified: Basic Community Treatment (4,133 Euro per six months); Intensive Community Treatment (6,180 Euro) and Rehabilitative Community Treatment (11,984 Euro) for 83%, 6% and 11% of frequent service users respectively. The model was found to be accurate for 85% of users. CONCLUSION: It is possible to develop predictive models to identify frequent service users and to assign them to pre-defined packages of care, and to use these models to inform the funding of psychiatric care.

[The cost and utilization of psychotherapy in community-based mental health services. A multicentre study in five Italian areas]. / Diffusione e costi delle psicoterapie nei DSM. Uno studio multicentrico in cinque aree Italiane.

AIMS: To investigate the prevalence of psychotherapy intervention in five Italian Centres for Mental Health. Analysing sociodemographic characteristics, geographical differences, frequencies of psychotherapy interventions, and the costs of these interventions. METHODS: Five Italian Community-based Psychiatric Services collected data from 1250 patients during October 2002. Socio-demographic and clinical characteristics and GAF scores were collected at baseline. All psychiatric contacts during the following six months were recorded and categorised into 24 service contact categories. A comparison between patients who received or did not receive psychotherapy was made. RESULTS: The socio-demographic characteristics of patients are very similar to those found in previous studies; there is a great difference in the number of psychotherapy treatments between the five areas. Psychotherapy patients use different services compared to the other patients, and their care cost less. CONCLUSIONS: This study provides a description of the provision of psychotherapy by Italian Mental Health Services. Further research is required into this topic.

[Proposal for a new funding system for mental health departments. Results from an evaluative multicentre Italian study (I-psycost)]. / Proposta per un nuovo sistema di finanziamento dei dipartimenti di salute mentale. Risultati di uno studio valutativo multicentrico nazionale (I-psycost study).

AIMS: To obtain a new, well-balanced mental health funding system, through the creation of (i) a list of psychiatric interventions provided by Italian Community-based Psychiatric Services (CPS), and associated costs; (ii) a new prospective funding system for patients with a high use of resources, based on packages of care. METHODS: Five Italian Community-based Psychiatric Services collected data from 1250 patients during October 2002. Socio-demographical and clinical characteristics and GAF scores were collected at baseline. All psychiatric contacts during the following six months were registered and categorised into 24 service contact types. Using elasticity equation and contact characteristics, we estimate the costs of care. Cluster analysis techniques identified packages of care. Logistic regression defined predictive variables of high use patients. Multinomial Logistic Model assigned each patient to a package of care. RESULTS: The sample's socio-demographic characteristics are similar, but variations exist between the different CPS. Patients were then divided into two groups, and the group with the highest use of resources was divided into three smaller groups, based on number and type of services provided. CONCLUSIONS: Our findings show how is possible to develop a cost predictive model to assign patients with a high use of resources to a group that can provide the right level of care. For these patients it might be possible to apply a prospective per-capita funding system based on packages of care.

Incidence of chronic thromboembolic pulmonary hypertension after pulmonary embolism.

BACKGROUND: Chronic thromboembolic pulmonary hypertension (CTPH) is associated with considerable morbidity and mortality. Its incidence after pulmonary embolism and associated risk factors are not well documented. METHODS: We conducted a prospective, long-term, follow-up study to assess the incidence of symptomatic CTPH in consecutive patients with an acute episode of pulmonary embolism but without prior venous thromboembolism. Patients with unexplained persistent dyspnea during follow-up underwent transthoracic echocardiography and, if supportive findings were present, ventilation-perfusion lung scanning and pulmonary angiography. CTPH was considered to be present if systolic and mean pulmonary-artery pressures exceeded 40 mm Hg and 25 mm Hg, respectively; pulmonary-capillary wedge pressure was normal; and there was angiographic evidence of disease. RESULTS: The cumulative incidence of symptomatic CTPH was 1.0 percent (95 percent confidence interval, 0.0 to 2.4) at six months, 3.1 percent (95 percent confidence interval, 0.7 to 5.5) at one year, and 3.8 percent (95 percent confidence interval, 1.1 to 6.5) at two years. No cases occurred after two years among the patients with more than two years of follow-up data. The following increased the risk of CTPH: a previous pulmonary embolism (odds ratio, 19.0), younger age (odds ratio, 1.79 per decade), a larger perfusion defect (odds ratio, 2.22 per decile decrement in perfusion), and idiopathic pulmonary embolism at presentation (odds ratio, 5.70). CONCLUSIONS: CTPH is a relatively common, serious complication of pulmonary embolism. Diagnostic and therapeutic strategies for the early identification and prevention of CTPH are needed.
