The main goal of this project was to evaluate the clinical and sociodemographic characteristics of patients hospitalized with schizophrenia or bipolar disorder and the register of legal circumstances. A descriptive study was conducted using a nationwide hospitalization administrative database that contains all admissions registered in public hospitals across mainland Portugal. All discharges between 2008 and 2015 with a primary diagnosis of schizophrenia or bipolar disorder were selected. Legal problems (LP) at the moment of hospitalization were identified based on the presence of a secondary diagnosis of the ICD-9-CM code V62.5 ‘Legal circumstances: Imprisonment; Legal investigation; Litigation; or Prosecution’. A total of 25,835 and 20,807 hospitalizations with a primary diagnosis of schizophrenia and bipolar disorder were analysed, respectively. Approximately 11.8% (n = 3,005) of schizophrenia hospitalizations and 6.0% (n = 1250) of bipolar disorder hospitalizations were associated with registered legal circumstances. Legal circumstances were associated with younger patients, male sex, and a longer length of stay. One in four episodes linked to LP was associated with drug abuse and/or dependence.

To characterize all hospitalizations held in mainland Portugal (2010–2015) with dementia-related agitation based on International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) coding, and to investigate whether there is a relationship between agitation and hospitalization outcomes. A retrospective observational study was conducted using an administrative dataset containing data from all mainland Portuguese public hospitals. Only hospitalization episodes for patients aged over 65 years who have received a dementia diagnosis ascertained by an ICD-9-CM code of dementia with behavioral disturbance (294.11 and 294.21) and dementia without behavioral disturbance (294.10 and 294.20) were selected. Episodes were further grouped according to the presence of an agitation code. For each episode, demographic data and hospitalization outcomes, including length of stay (LoS), in-hospital mortality, discharge destination and all-cause hospital readmissions, were sourced from the dataset. Comparative analyses were performed and multivariable logistic methods were used to estimate the adjusted associations between agitation (exposure) and outcomes. Overall, 53,156 episodes were selected, of which 6,586 had an agitation code. These were mostly related to male, younger inpatients (mean 81.19 vs. 83.29 years, p < 0.001), had a higher comorbidity burden, stayed longer at the hospital (median 9.00 vs. 8.00 days, p < 0.001) and frequently ended being transferred to another facility with inpatient care. Agitation was shown to independently increase LoS (aOR = 1.385; 95%CI:1.314–1.461), but not the risk of a fatal outcome (aOR = 0.648; 95%CI:0.600–0.700). These results support the importance of detecting and managing agitation early on admission, since its prompt management may prevent lengthy disruptive hospitalizations. [ABSTRACT FROM AUTHOR]

Depression is a prevalent disease, being one of the most relevant contributors of disability in the overall global burden of diseases. Hospitalization episodes are important quality indicators in psychiatric care. The primary aim of this study is to analyse depressive disorder related hospitalizations in Portuguese public hospitals and to detail clinical and sociodemographic differences among various subtypes of depression. Admissions with a primary diagnosis of depression in adult patients(> = 18 years) were selected from a national mainland hospitalization database. ICD-9-CM codes were used to select the diagnoses of interest: 296.2 × to 296.3x (Major depressive disorder), 300.4 (Dysthymic disorder) and 311 (Depressive disorder, not elsewhere classified). Birth date, sex, residence address, primary and secondary diagnoses, admission date, discharge date, length of stay (LoS), discharge status, and hospital estimated charges were obtained. A total of 28,569 hospitalizations (22,387 patients) with a primary diagnosis of depression were analysed. In the 8-year period of the study, 19.1% of all hospitalizations with a primary diagnosis of psychiatric disorder were linked to Depression. Major Depressive episodes were the most common (n = 15,384; 53.8%), followed by Depression unspecified episodes (n = 6,793; 23.8%), and Dysthymia (n = 6,392; 22.4%). Most episodes occurred in female patients (70.2%; n = 20,052), with a mean age of 50.6 years, and 37.0% (n = 10,564) of the episodes were associated to other psychiatric comorbidities. Depressive disorders are one of the leading causes of hospitalization in Portuguese psychiatric departments, being responsible for approximately 1 in 5 hospitalizations with a psychiatric diagnosis.

Bipolar Disorder (BD) is a mental disorder which frequently requires long hospitalizations and need for acute psychiatric care. The aim of this study was to describe a nationwide perspective of BD related hospitalizations and to use a BigData based approach in mental health research. We performed a retrospective observational study using a nationwide hospitalization database containing all hospitalizations registered in Portuguese public hospitals from 2008-2015. Hospitalizations with a primary diagnosis of BD were selected based on International Classification of Diseases version 9, Clinical Modification (ICD-9-CM) codes of diagnosis 296.xx (excluding 296.2x; 296.3x and 296.9x). From 20,807 hospitalizations belonging to 13,300 patients, around 33.4% occurred in male patients with a median length of stay of 16.0 days and a mean age of 47.9 years. The most common hospitalization diagnosis in BD has the code 296.4x (manic episode) representing 34.3% of all hospitalizations, followed by the code 296.5x (depressed episode) with 21.4%. The mean estimated hospitalization charge was 3,508.5€ per episode, with a total charge of 73M€ in the 8-year period of this study.This is a nationwide study giving a broad perspective of the BD hospitalization panorama at a national level. We found important differences in hospitalization characteristics by sex, age and primary diagnosis. [ABSTRACT FROM AUTHOR]

The coronavirus disease 2019 pandemic (COVID-19) has an important direct and indirect impact on both physical and mental health. We aim to describe the impact of an emergency state period due to COVID-19 on psychiatric emergency department (ED) visits. We conducted a retrospective observational study analysing all emergency visits occurring at a metropolitan psychiatric ED between March 19th and May 2nd 2019 and 2020 (the beginning/end date of the emergency state which Portugal was under due to COVID-19). Data regarding age, sex, diagnoses, admission date, discharge destiny and status were collected. Diagnoses were classified using the International Classification of Diseases version 9, Clinical Modification (ICD-9-CM). There was a 52·2% decrease on the number of psychiatric emergency visits during the emergency state period (n2020 = 780 vs n2019 = 1633 episodes). The decrease on psychiatric ED visits was greater in the female sex and in the younger age groups. Episodes with a primary diagnosis of Mood disorders lead the decrease on psychiatric ED visits with 68·3% less episodes. Schizophrenia and other psychotic disorders was the diagnosis group with the smaller decline (9·8% decrease). COVID-19 emergency state period had an important impact on the number and characteristics of psychiatric ED visits, reinforcing the great indirect effects of COVID-19 on mental health.

Schizophrenia is a mental disorder characterized by long hospitalizations and frequent need for chronic/acute psychiatric care. Hospitalizations represent a valuable quality of care indicator in schizophrenia patients. The aim of this study was to describe a nationwide perspective of schizophrenia related hospitalizations. We performed a retrospective observational study using a nationwide hospitalization database containing all hospitalizations registered in Portuguese public hospitals from 2008 to 2015. Hospitalizations with a primary diagnosis of schizophrenia were selected based on the definition by CCS – Clinical Classification Software diagnostic single-level 659. Schizophrenia subtypes were identified based on International Classification of Diseases version 9, Clinical Modification (ICD-9-CM) codes of diagnosis 295.xx. A total of 25,385 hospitalizations were registered belonging to 14,279 patients. 68.0% of the hospitalizations occurred in male patients and the median length of stay was 18.0 days. In male patients' hospitalizations, the most frequent age group was 31–50 years followed by the age group of 18–30 years (55.9 and 24.0% respectively). For female patients, the most frequent age group was 31–50 years followed by 51–70 years (54.1 and 22.6%, respectively). There were 73 hospitalization with a deadly outcome (0.29%). Paranoid type was the most frequent subtype of schizophrenia (50.5%). The mean hospitalization charges were 3509.7€ per episode, with a total charge of 89.1 M€ in the 8-year period. This is a nationwide study using Big Data analysis giving a broad perspective of schizophrenia hospitalization panorama at a nationwide level. We found differences in hospitalization characteristics according to patients' gender, age and primary diagnosis. [ABSTRACT FROM AUTHOR]

• From 27,785 epilepsy-related hospitalizations, 33.9% had a registered mental disorder. • Registered mental disorders were more common in males and older inpatients. • Comorbid mental disorders increased the use of healthcare resources. • The most frequently registered mental disorders were alcohol-related disorders. • The need to timely manage comorbid psychopathology is highlighted. Psychiatric comorbidities are highly frequent in people with epilepsy and were found to be markers of poorer prognosis. These comorbidities increase the use of healthcare resources, including emergency department visits and inpatient care. Despite this, there is little information on healthcare utilization associated with a wide range of comorbid mental disorders in people with epilepsy (PWE). To characterize registered mental disorders among all hospitalizations with a primary diagnosis of epilepsy and to analyze their association with crucial hospitalization outcomes. An observational retrospective study was performed using administrative data from hospitalization episodes with epilepsy as the primary diagnosis discharged between 2008 and 2015. Mental disorder categories 650 to 670 from Clinical Classification Software were selected as secondary diagnoses. Mann-Whitney U, Kruskall-Wallis, and Chi-squared tests were used to establish comparisons. For each episode, data regarding hospitalization outcomes was retrieved, including length of stay (LoS), in-hospital mortality (IHM), 8-year period readmissions, and total estimated charges. Overall, 27,785 hospitalizations were analyzed and 33.9% had registered mental disorders, with alcohol-related disorders being the most prevalent (11.7%). For episodes with a concomitant register of a mental disorder, LoS was significantly longer (5.0 vs. 4.0 days, P <0.001), and IHM was higher (2.8% vs. 2.2%, P <0.001), as were readmissions (25.5% vs. 23.7%, P <0.001), and median episodes' charges (1,578.7 vs. 1,324.4 euros, P <0.001). Epilepsy-related hospitalizations with registered mental disorders heightened the utilization of healthcare resources, stressing the importance of diagnosing and treating mental disorders in PWE.

Objective: Patients hospitalized with multiple myeloma (MM) are particularly vulnerable to depression. The present study aims to determine the frequency of depression among MM hospitalized patients, in order to assess the possible differences between those with and without depression in relation to sociodemographic and clinical variables and to measure the impact of depression on hospitalization outcomes. Methods: An observational retrospective study was performed using an administrative data set of all hospitalizations with a primary diagnosis of MM between 2000 and 2015 in Portuguese mainland public hospitals. Codes related to depressive disorders were grouped to generate the dichotomous variable of depression (yes/no). A multivariate analysis was conducted and adjusted odd ratios (aOR) calculated between different variables and depression. Results: Of a total of 14.575 MM hospitalizations studied, a concurrent code of depression was registered in 666 patients (4.6%). A greater odds of depression was observed in female patients (aOR = 2.26; 95%CI = 1.91‐2.66), transplanted patients (aOR = 1.78; 95%CI = 1.44‐2.20), patients with plasma cell leukemia (aOR = 1.79; 95%CI = 1.22‐2.64) and patients with a higher Charlson Comorbidity Index (CCI) (aOR = 1.10; 95%CI = 1.05‐1.15). Length of stay was longer in patients with a registered diagnosis of depression (aOR = 1.01; 95%CI = 1.01‐1.02) while the odds of in‐hospital mortality were lower in these patients (aOR = 0.53; 95%CI = 0.41‐0.68). Conclusions: These results may help identify MM inpatients at higher risk of presenting depression (female gender, younger age, high CCI, plasma cell leukemia, transplant procedure). This will enable timely psychological assessment and treatment to prevent worse outcomes and higher healthcare costs associated with depression. [ABSTRACT FROM AUTHOR]

Objectives: We aimed to describe and correlate the hospital panorama of psychotic disorders (PD) with cannabis use (CU) trends in all Portuguese public hospitals. Methods: We conducted a retrospective observational study that analysed all hospitalizations that occurred in Portuguese public hospitals from 2000 to 2015. Hospitalizations with a primary diagnosis of PD or schizophrenia were selected based on Clinical Classification Software diagnostic single‐level 659. Episodes associated with CU were identified by the International Classification of Diseases Version 9, Clinical Modification code 304.3/305.2 that correspond to cannabis dependence/cannabis abuse. Results: The number of hospitalizations with a primary diagnosis of PD and schizophrenia associated with CU rose 29.4 times during the study period, from 20 to 588 hospitalizations yearly (2000 and 2015, respectively) with a total of 3,233 hospitalizations and an average episode cost of €3,500. Male patients represented 89.8% of all episodes, and the mean/median age at discharge were 30.66/29.00 years, respectively. From all hospitalizations with a primary diagnosis of PD or schizophrenia, the ones with a secondary diagnosis of CU rose from 0.87% in 2000 to 10.60% in 2015. Conclusions: The increase on secondary diagnosis coding and the change on cannabis patterns of consumption in Portuguese population with an increasing frequency of moderate/high dosage cannabis consumers may explain the rise on PD hospitalizations.

Introduction: Recent evidence suggests that incidence of Anorexia nervosa (AN) has remained stable over the last decades in Western Europe, while decreasing for Bulimia nervosa (BN). It is well‐known that most individuals with an ED (Eating disorder) do not seek medical treatment. Objective: The present study analyses hospitalizations related with EDs held in mainland Portuguese public hospitals between 2000 and 2014. Method: A retrospective observational study was performed gathering all inpatient episodes with primary or secondary diagnosis of ED. Number of patients, gender, mean age at discharge, suicide‐attempts related hospitalizations, in‐hospital mortality, length of stay, and mean charges were analyzed. Results: There were a total of 4,485 hospitalizations with an associated ED. AN was the most frequent ED (n = 2,806). Suicide attempt‐related hospitalizations were most common among patients with BN (10.1% of BN hospitalizations) or AN (5.2% of AN hospitalizations). Discussion: AN has higher in‐hospital mortality than BN. We observed a higher proportion of suicide related hospitalizations in BN when compared to AN. Although pica, rumination disorder, and psychogenic vomiting represent a smaller portion of all EDs, this study was the first to describe hospitalization trends for this set of EDs for a 15‐year period, to the best of our knowledge.

Background: Pertussis has caused several outbreaks and concern worldwide. Despite high vaccination coverage, people of all ages are still affected with significant morbidity and mortality. We aimed to analyse all pertussis hospitalizations in Portugal to help to delineate preventive policies. Methods: Data were collected from a Portuguese administrative database, which contains all registered hospitalizations in mainland Portugal. Cases were identified using the ICD-9-CM code 033.x (whooping cough) as principal or secondary diagnosis, with hospital discharges between 2000 and 2015. Data were analysed by age groups. Results: Of 2281 hospitalizations, 94% occurred in infants (<1 year). The mean and median ages were 20 and 2 months, respectively. A seasonal pattern was observed, with higher number of hospitalizations during the winter for infants, and during the summer for other age groups. Higher hospitalization rates were registered in the Southern regions. The mean and median lengths of hospital stay were 8 and 6 days, respectively. The main complications were acute respiratory failure and pneumonia. Invasive or non-invasive ventilation, or both, was required in 2.4, 1.8 and 0.6% of hospitalized cases, respectively. The overall inpatient case fatality rate was 0.7%; 0.8, 11.5 and 17.4% for the age groups 0-1 months, 18-64 years and ≥65 years, respectively. Total hospitalization costs were estimated to be 2,698,995€. Conclusion: Our study emphasizes the need to adopt new preventive strategies mainly focused on infants, to reduce morbidity and costs of hospitalizations related to pertussis. [ABSTRACT FROM AUTHOR]

Objectives: Legal abortion based purely in maternal option without fetal/maternal pathology was liberalised in Portugal in 2007 and since then abortion rates have increased substantially. The aim of this paper was to study the impact of the liberalisation of abortion by maternal request on total legal abortion related hospitalisation trends.Study Design: We considered hospitalisations of legal abortion (ICD-9-CM codes 635.x) with discharges from 2000 to 2014. Data was obtained from a Portuguese administrative database, which contains all registered public hospitalisations in mainland Portugal. Performed legal abortions during the same period were obtained from INE (National Statistics Institute). Hospitalisations per abortion were calculated by dividing the number of legal abortions hospitalisations per the number of legal abortions, mean ages, number of hospitalisations per age group, complications, admission type and length of stay were also analysed, throughout the study period.Results: Hospitalisations rose during the study period, (from 618 episodes in 2000 to 1,259 in 2014, with a peak of 1,603 in 2010). Since the liberalisation law was passed there was a significant decrease in the number of hospitalisations per abortion: from 1.07 in 2000 to 0.11 in 2014 (p<0.001). Furthermore, the mean age maintained stable since liberalisation (30.8 years before 2007 and 31.0 after). Abortion related hospitalisations are more frequent in women aged 25-39. A significant decrease from the emergent to the scheduled type of admission occurred from 2000 to 2014 (from 83.5% to 56.7% of emergent admissions) (p<0.001). Complications remained stable between 2000 and 2014 and delayed or excessive haemorrhage was the most frequent (4.6%).Conclusions: Since the liberalisation, hospitalisations per abortion have decreased, reflecting the major impact that the liberalisation of legal abortion by maternal request had on abortion trends nationwide. Before the liberalisation, each abortion led to approximately one hospitalisation while after the liberalisation this trend shifted to approximately 10% of the number of abortions. Legal abortion related hospitalisations are more frequent in women aged between 25 and 39 years old, an older age group when compared to the one registered in all cases of legal abortions, reflecting the differences between those hospitalised and those who are not. Our study shows the impact that legal abortion by maternal request liberalisation law can bring to abortion and to hospitalisation trends. [ABSTRACT FROM AUTHOR]

Suicidal behaviors are a serious but potentially preventable cause of premature death. Increased awareness of the importance of mental health for global health has led to new initiatives, supported by the World Health Organization (WHO) and the United Nations (UN). The suicide mortality rate is one of the indicators covered in the UN's Sustainable Development Goal (SDG) 3. The aim of this study is to identify the scientific production and its temporal evolution related to the suicide mortality rate indicator in the context of mental disorders and as one of the SDG. A bibliometric analysis was performed in Scopus to assess the related research on suicide mortality rate, including on the context of the third SDG, from inception to September 2, 2020. The set of articles were analyzed for bibliometric measures. A total of 3126 documents about mental health and suicide mortality rate on the context of SDG were collected. Articles were the predominant type of literature on this area (78.3%), with significant expression on the last years, more evident around 2015, the year of adoption of SDGs. Despite a large volume of evidence, the debate about suicide mortality rate as an indicator of SDG is still very sparse suggesting a need for better consensus on its evaluation methods. This study presents useful characteristics for the formulation of new studies and provides specific targets for the construction or improvement of public policies on the context of the SDGs for further discussion on this strategy proposed by the UN.

Background: Pediatric Bipolar Disorder (BD) has been the focus of increased attention. To date, in Portugal, there is no evidence available for pediatricBD-related hospitalization rates. This study aimed to describe and characterize all pediatric hospitalizations with a primary diagnosis of BD registered in Portugal from 2000 to 2015.Methods: A retrospective observational study was conducted. Pediatric (< 18 years) inpatient episodes with a primary diagnosis of BD were selected from a national administrative database. The ICD-9-CM codes 296.x (excluding 296.2x, 296.3x and 296.9x) identified the diagnosis of interest. Additionally, age at discharge, sex, psychiatric comorbidities, length of stay (LoS), admission type and date, in-hospital mortality and hospital charges were analyzed.Results: A total of 348 hospitalizations, representing 258 patients, were identified. The overall population-based rate of hospitalizations was 1.18/100 000 youths. A non-linear increase throughout the study period was found. Patients were mostly female (60.6%), with a median age of 16 years (Q1-Q3:14-17). Admissions were mostly emergent (81%), and the median LoS was 14 days (Q1-Q3:7-24). Moreover, about 26% of all episodes were readmissions. Mean estimated charges per episode were 3503.10€, totalizing 1.20M€.Limitations: Limitations include the use of secondary data and the retrospective nature of the study.Conclusions: Annual rates of pediatric BD hospitalizations showed a non-linear increase. These findings may contribute to better understand the pediatric BD burden. Nevertheless, more research is warranted, to better characterize sociodemographic and clinical trends in pediatric BD to prevent the high number of acute hospitalizations and readmissions of these patients.

Background: This study aimed to use the Charlson Comorbidity Index (CCI) to assess the prevalence of medical comorbidities among hospitalization episodes with a primary Bipolar Disorder (BD) diagnosis, and to analyze its association with hospitalization outcomes.Methods: A population-based observational retrospective study was conducted using a Portuguese administrative database containing all mainland public hospitalizations. From 2008-2015, hospitalization episodes with a primary diagnosis of BD were analysed. Outcomes included: length of stay (LoS), in-hospital mortality and discharge destination.Results: Overall, 20807 hospitalization episodes were analysed. Mean±standard deviation age at admission was 47.9±14.3 years, and these episodes mostly refer to women's admissions (66.6%). Median (1st quartile; 3rd quartile) LoS was 16.0 (9.0; 25.0) days. A total of 2145 (10.3%) episodes had ≥1 CCI comorbidities registered, being diabetes the most prevalent. LoS was significantly higher for episodes with secondary diagnoses of congestive heart failure, cerebrovascular disease, dementia, diabetes, renal disease and malignancy (all p<0.05). Episodes with a registry of myocardial infarction, peripheral vascular disease, malignancy and renal disease diagnoses had higher in-hospital mortality.Limitations: Limitations include the use of data registered for administrative reasons rather than research purposes, and the analysis of hospitalization episodes, instead of patients.Conclusions: In this Portuguese nationwide study, greater comorbidity had a measurable impact on BD hospitalization outcomes. During the study period the prevalence of CCI comorbidities rose from 8.1% to 17.4%, which may reflect the overall increasing quality of hospital-coded data in Portugal throughout the years. The detection and timely management of medical comorbid conditions will likely prevent the high BD medical burden. [ABSTRACT FROM AUTHOR]

Aims: To characterize the register of a secondary diagnosis of mental illnesses in all chronic obstructive pulmonary disease (COPD) hospitalizations registered in Portugal from 2008 to 2015 and explore their impact on hospitalization outcomes.A retrospective observational study was conducted. Hospitalizations of patients with at least 40 years old, discharged between 2008 and 2015 with a primary diagnosis of COPD (ICD-9-CM codes 491.x, 492.x and 496) were retrieved from a national administrative database. Comorbid psychiatric diagnoses were identified and defined by the HCUP Clinical Classification Software (CCS) category codes 650–670 (excluding 662). Length of hospital stay (LoS), admission type, in-hospital mortality, and estimated hospital charges were analyzed according to psychiatric diagnostic categories using sex and age-adjusted models.Of 66,661 COPD hospitalizations, 25,869 (38.8%) were episodes with a registered psychiatric comorbidity. These were more likely to correspond to younger inpatients (OR = 2.16, 95%CI 2.09–2.23; p < 0.001), to stay longer at the hospital (aOR = 1.08, 95%CI 1.05–1.12; p < 0.001), to incur in higher estimated hospital charges (aOR = 1.37, 95%CI 1.33–1.42; p < 0.001) and to be urgently admitted (aOR = 1.33, 95%CI 1.23–1.44; p < 0.001). After adjustment for age, in-hospital mortality was lower for episodes with psychiatric diagnoses (aOR = 0.90; 95%CI 0.84–0.96; p < 0.001), except for organic and neurodegenerative diseases category and developmental disorders, intellectual disabilities and disorders usually diagnosed in infancy, childhood, or adolescence category.These findings corroborate the additional burden placed by psychiatric disorders on COPD hospitalizations, highlighting the importance of individualizing care to address these comorbidities and minimize their impact on treatment outcomes.Methods: To characterize the register of a secondary diagnosis of mental illnesses in all chronic obstructive pulmonary disease (COPD) hospitalizations registered in Portugal from 2008 to 2015 and explore their impact on hospitalization outcomes.A retrospective observational study was conducted.

Nowadays, evaluating the quality of health services, especially in primary health care (PHC), is increasingly important. In a historical perspective, the Department of Health (United Kingdom) developed and proposed a range of indicators in 1998, and lately several health, social and political organizations have defined and implemented different sets of PHC quality indicators. Some systematic reviews in PHC quality indicators are reported but only in specific contexts and conditions. The aim of this study is to characterize and provide a list of indicators discussed in the literature to support managers and clinicians in decision-making processes, through an umbrella review on PHC quality indicators. The methodology was performed according to PRISMA Statement. Indicators from 33 eligible systematic reviews were categorized according to the dimensions of care, function, type of care, domains and condition contexts. Of a total of 727 indicators or groups of indicators, 74.5% (n = 542) were classified in process category and 89.5% (n = 537) with chronic type of care (n = 428; 58.8%) and effective domain (n = 423; 58.1%) with the most frequent values in categorizations by dimensions. The results of this overview of reviews are valuable and imply the need for future research and practice regarding primary health care quality indicators in the most varied conditions and contexts to generate new discussions about their use, comparison and implementation.
