Neuropsychiatric inventory questionnaire (NPI-Q): A validity study of the Dutch form

The Neuropsychiatric Inventory is a clinical instrument for assessing behavioral and psychological symptoms in dementia. It is based on an interview with the primary caregiver. A brief questionnaire form of the NPI was developed, intended for use in routine clinical practice (NPI-Q). This study evaluates the validity of the NPI-Q Dutch form. The NPI-Q was compared to other questionnaires, i.e. the Revised Memory and Behavioural Problems Checklist (RMBPC), the short form Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE-N), the 15 items Geriatric Depression Scale (GDS-15) and the Cognitive Screening Test (CST-20). A data set was used of geriatric outpatients who were referred for neuropsychological assessment (n = 29). Correlations between the NPI-Q and RMBPC Depression- and Disinhibition subscales were relatively high. No relationship was found between the NPI-Q and the RMBPC Memory related behavioral changes subscale, or between the NPI-Q and the IQCODE-N and the CST-20. Informant ratings on the NPI-Q depression-item were related with patient ratings on the GDS-15, especially when patients were relatively mildly cognitive impaired. Caregiver distress was strongly associated with NPI-Q symptom assessment. In conclusion: our preliminary results support validity of the NPI-Q Dutch form. It is a practical rating scale for assessing neuropsychiatric symptoms in dementia and associated caregiver distress.     

Relation between bed use,social deprivation,and overall bed availability in acute adult psychiatric units,and alternative residential options: a cross sectional survey,one day census data,and staff interviews.

OBJECTIVES: To examine the relation between bed use, social deprivation, and overall bed availability in acute adult psychiatric units and to explore the range of alternative residential options. DESIGN: Cross sectional survey, combined with one day census data; ratings by and interviews with staff; examination of routine data sources. SETTINGS: Nationally representative sample of acute psychiatric units. SUBJECTS: 2236 patients who were inpatients on census day. MAIN OUTCOME MEASURES: Bed occupancy levels, judged need for continuing inpatient care, reasons preventing discharge, scores on the Health of the Nation outcome scales. RESULTS: Bed occupancy was related to social deprivation and total availability of acute beds (r = 0.66, 95% confidence interval 0.19 to 0.88, F = 8.72, df = 2.23; P = 0.002). However, 27% (603/2215) of current inpatients (61% (90/148) of those with stays of > 6 months) were judged not to need continuing admission. The major reasons preventing discharge were lack of suitable accommodation (37% (176/482) of patients in hospital < 6 months v 36% (31/86) of those in hospital > 6 months); inadequate domiciliary based community support (23% (113) v 9% (8)); and lack of long term rehabilitation places (21% (100) v 47% (40)). Scores on the Health of the Nation outcome scale were generally consistent with these staff judgments. CONCLUSIONS: The shortage of beds in acute psychiatric units is related to both social deprivation and the overall availability of acute beds. Patients currently inappropriately placed on acute admission wards should be relocated into more suitable accommodation, either in hospital or in the community. A range of provisions is required; simply providing more acute beds is not the answer.     

SUICIDE PROBLEMS IN MEDICAL PRACTICE

Increasing awareness by physicians in general medical practice of the possibility of suicide in nonpsychiatric patients is indispensable for the evaluation of suicide risk and for a practical approach to the problem of prevention.An analysis was made of the records of 11 cases of suicide by medical and surgical patients who were in a general nonpsychiatric Veterans Administration hospital for evaluation and treatment of physical disease.It was noted that the general hospital staff had a low index of suspicion of the possibility of suicide in general hospital patients.It appeared from this study that there is a definite suicide risk in older persons hospitalized for physical illness who develop psychotic reactions during the course of their illness and hospitalization. The signs and symptoms of toxic and organic psychosis in these older patients were not recognized and their significance relative to suicide risk was not appreciated. Although psychiatric signs of severe emotional disturbance appeared clinically obvious at least 24 hours before suicide in ten of the eleven patients, no suicide risk was considered present, nor were adequate precautions taken by the hospital staff. This was owing to the lack of psychiatric orientation among the nonpsychiatric physicians.     

Hospitalized children with 2009 pandemic influenza A (H1N1): comparison to seasonal influenza and risk factors for admission to the ICU

Background

Limited data are available describing the clinical presentation and risk factors for admission to the intensive care unit for children with 2009 H1N1 infection.

Methods

We conducted a retrospective chart review of all hospitalized children with 2009 influenza A (H1N1) and 2008–09 seasonal influenza at The Children''s Hospital, Denver, Colorado.

Results

Of the 307 children identified with 2009 H1N1 infections, the median age was 6 years, 61% were male, and 66% had underlying medical conditions. Eighty children (26%) were admitted to the ICU. Thirty-two (40%) of the ICU patients required intubation and 17 (53%) of the intubated patients developed acute respiratory distress syndrome (ARDS). Four patients required extracorporeal membrane oxygenation. Eight (3%) of the hospitalized children died. Admission to the ICU was significantly associated with older age and underlying neurological condition. Compared to the 90 children admitted during the 2008–09 season, children admitted with 2009 H1N1 influenza were significantly older, had a shorter length of hospitalization, more use of antivirals, and a higher incidence of ARDS.

Conclusions

Compared to the 2008–09 season, hospitalized children with 2009 H1N1 influenza were much older and had more severe respiratory disease. Among children hospitalized with 2009 H1N1 influenza, risk factors for admission to the ICU included older age and having an underlying neurological condition. Children under the age of 2 hospitalized with 2009 H1N1 influenza were significantly less likely to require ICU care compared to older hospitalized children.     

A comparison of olanzapine and risperidone on the risk of psychiatric hospitalization in the naturalistic treatment of patients with schizophrenia

BACKGROUND: Decreasing hospital admissions is important for improving outcomes for people with schizophrenia and for reducing cost of hospitalization, the largest expenditure in treating this persistent and severe mental illness. This prospective observational study compared olanzapine and risperidone on one-year psychiatric hospitalization rate, duration, and time to hospitalization in the treatment of patients with schizophrenia in usual care. METHODS: We examined data of patients newly initiated on olanzapine (N = 159) or risperidone (N = 112) who continued on the index antipsychotic for at least one year following initiation. Patients were participants in a 3-year prospective, observational study of schizophrenia patients in the US. Outcome measures were percent of hospitalized patients, total days hospitalized per patient, and time to first hospitalization during the one-year post initiation. Analyses employed a generalized linear model with adjustments for demographic and clinical variables. A two-part model was used to confirm the findings. Time to hospitalization was measured by the Kaplan-Meier survival formula. RESULTS: Compared to risperidone, olanzapine-treated patients had significantly lower hospitalization rates, (24.1% vs. 14.4%, respectively, p = 0.040) and significantly fewer hospitalization days (14.5 days vs. 9.9 days, respectively, p = 0.035). The mean difference of 4.6 days translated to $2,502 in annual psychiatric hospitalization cost savings per olanzapine-treated patient, on average. CONCLUSIONS: Consistent with prior clinical trial research, treatment-adherent schizophrenia patients who were treated in usual care with olanzapine had a lower risk of psychiatric hospitalization than risperidone-treated patients. Lower hospitalization costs appear to more than offset the higher medication acquisition cost of olanzapine.     

Eficacia y eficiencia de las unidades geriátricas de agudos: un tópico clásico revisitado

Previous meta-analyses have shown that the hospital admission of older patients in acute geriatric units (AGU) compared to admission to other conventional units, significantly reduced the risk of functional deterioration during hospitalization, increasing the possibility of returning home, with an added reduction in cost of hospitalization. A new meta-analysis on the subject has recently been published in Age and Aging, which adds six new studies to the five clinical trials analyzed in previous meta-analyses. This article analyzes the results of this new meta-analysis, delving into the characteristics of the new studies included and making some considerations on the implications for care in the future development of AGU.     

Influential Factors for and Outcomes of Hospitalized Patients with Suicide-Related Behaviors: A National Record Study in Taiwan from 1997–2010

Background

Investigating the factors related to suicide is crucial for suicide prevention. Psychiatric disorders, gender, socioeconomic status, and catastrophic illnesses are associated with increased risk of suicide. Most studies have typically focused on the separate influences of physiological or psychological factors on suicide-related behaviors, and have rarely used national data records to examine and compare the effects of major physical illnesses, psychiatric disorders, and socioeconomic status on the risk of suicide-related behaviors.

Objectives

To identify the characteristics of people who exhibited suicide-related behaviors and the multiple factors associated with repeated suicide-related behaviors and deaths by suicide by examining national data records.

Design

This is a cohort study of Taiwan’s national data records of hospitalized patients with suicide-related behaviors from January 1, 1997, to December 31, 2010.

Participants

The study population included all people in Taiwan who were hospitalized with a code indicating suicide or self-inflicted injury (E950–E959) according to the International Classification of Disease, Ninth Revision, Clinical Modification.

Results

Self-poisoning was the most common method of self-inflicted injury among hospitalized patients with suicide-related behaviors who used a single method. Those who were female, had been hospitalized for suicide-related behaviors at a younger age, had a low income, had a psychiatric disorder (i.e., personality disorder, major depressive disorder, bipolar disorder, schizophrenia, alcohol-related disorder, or adjustment disorder), had a catastrophic illness, or had been hospitalized for suicide-related behaviors that involved two methods of self-inflicted injury had a higher risk of hospitalization for repeated suicide-related behaviors. Those who were male, had been hospitalized for suicide-related behaviors at an older age, had low income, had schizophrenia, showed repeated suicide-related behaviors, had a catastrophic illness, or had adopted a single lethal method had an increased risk of death by suicide.

Conclusions

High-risk factors should be considered when devising suicide-prevention strategies.     

De relatie van psychiatrische functiestoornissen met cognitie, activiteiten dagelijks leven (ADL) en biografische gegevens

Psychiatric function disorders: association with cognitive function, activities of daily living and biographical data Background: The prevalence of non-cognitive, psychiatric function disorders (PFD) in psychogeriatric patients, staying in a nursing home is high; it varies from 70 to 80%. It has a negative impact on the quality of life and life-expectancy. It affects caregiver distress and is an important predictor of permanent admission to an institution. In addition the PFD has predictive potentialities for discharge from reactivation programmes and survival. Although there is a relationship between PFD (measured by NPI) and cognitive function disorders it has to be stated explicitly that from psychiatric point of view these two entities have to be distinguished. This distinction, already been studied by this research group, needed to be replicated in another population. Objective is to estimate 1) to which degree the prevalence of PFD in psychogeriatric patients, referred to a policlinics for cognitive function disorders (Index condition), differs from community dwelling psychogeriatric patients at referral to clinical and transmural nursing home programmes (Reference condition); 2) to which degree PFD is associated with both cognitive function disorders, activities of daily living for the two conditions; 3) to which degree PFD is associated with relevant general details of the patient, particularly gender, age and marital status, for the two conditions. Methods: In the Index condition particated patients aged ≥ 65 years suffering from cognitive function disorders (N=70) who were referred to a policlinic for cognitive function disorders who were suspected to suffer from psychiatric function disorders. For 35 patients of them complete data on NPI, MMSE en Barthel Index (BI) were available. In the Reference condition participated patients (age ≥ 65), who were referred to clinical and transmural nursing home programmes and who suffered from cognitive function disorders (MMSE ≥ 29) (N=487). For 385 patients of them all data on NPI, MMSE and BI were available. Results: Of all patients 92% suffered from at least one NPI symptom; 82% from two or more. Depression, Apathy, Anxiety and Irritability had high prevalences in the two samples. Application of logistic regression analysis for the prediction of total as well as individual NPI-symptoms showed that the prognostic potentialities of MMSE, BI and biographic data were very limited (R² = 0.11; max.). The non-metric princal component analysis and confirmatory factor analysis of NPI, MMSE and BI for the two samples, showed that MMSE and BI loaded highly on the dimension ‘Cognition’ and NPI on the dimension ‘Psychiatric function disorders’. The dimensional structure of the two samples did not show significant differences. Conclusion: The dimensional structure of the Index condition highly corresponded to the Reference condition; that is to say that the PFD appeared to be relatively independent of cognition and ADL. High prevalences of PFD (NPI), the broad variance of NPI-symptoms and the limited prognostic importance of MMSE, BI and general details for total NPI-score as well as individual NPI-symptoms were confirmed in both conditions. The dimension ‘Psychiatric function disorder’ was relative independent of the dimension ‘Cognition’. As a result it is of clinical interest - in case of referral to clinical and transmural programmes - to distinguish the psychiatric dimension from the cognitive dimension.

Cognitive and behavioural impairment among elderly people in institutions providing different levels of care.

OBJECTIVE: To compare the prevalence and degree of cognitive and behavioural impairment in elderly patients in institutions providing different levels of care. DESIGN: Prevalence study. SETTING: A nursing home, a home for the aged and psychogeriatric wards in a provincial psychiatric hospital. PATIENTS: Only subjects 65 years of age or older were eligible for inclusion. A random sample was selected comprising 25% of the residents in the nursing home and the home for the aged; of the 119 asked to participate 95 agreed (44 in the nursing home and 51 in the home for the aged). All 50 on the psychogeriatric wards agreed to participate. MAIN OUTCOME MEASURES: The Mini-Mental State Examination (MMSE) and the Kingston Dementia Rating Scale (KDRS). RESULTS: An MMSE score of less than 24 (cognitive impairment) was given to 37 (84%) of the residents in the nursing home, 43 (84%) of those in the home for the aged and 48 (96%) of the patients in the psychiatric hospital; the corresponding numbers for a KDRS score of more than 0 (cognitive impairment) were 41 (93%), 48 (94%) and 50 (100%). The seven patients receiving the highest level of care at the home for the aged (special care) had more behavioural problems than those in the psychiatric hospital did (p less than 0.001). CONCLUSIONS: Cognitive and behavioural impairment was widespread in the three institutions regardless of the level of care. When planning services and allocating resources government funding agencies should consider the degree and prevalence of such impairment among elderly people in institutions.     

Predictive Validity of the Suicide Trigger Scale (STS-3) for Post-Discharge Suicide Attempt in High-Risk Psychiatric Inpatients

Background

The greatly increased risk of suicide after psychiatric hospitalization is a critical problem, yet we are unable to identify individuals who would attempt suicide upon discharge. The Suicide Trigger Scale v.3 (STS-3), was designed to measure the construct of an affective ‘suicide trigger state’ hypothesized to precede a suicide attempt (SA). This study aims to test the predictive validity of the STS-3 for post-discharge SA on a high-risk psychiatric-inpatient sample.

Methods

The STS-3, and a psychological test battery measuring suicidality, mood, impulsivity, trauma history, and attachment style were administered to 161 adult psychiatric patients hospitalized following suicidal ideation (SI) or SA. Receiver Operator Characteristic and logistic regression analyses were used to assess prediction of SA in the 6-month period following discharge from hospitalization.

Results

STS-3 scores for the patients who made post-discharge SA followed a bimodal distribution skewed to high and low scores, thus a distance from median transform was applied to the scores. The transformed score was a significant predictor of post-discharge SA (AUC 0.731), and a subset of six STS-3 scale items was identified that produced improved prediction of post-discharge SA (AUC 0.814). Scores on C-SSRS and BSS were not predictive. Patients with ultra-high (90^th percentile) STS-3 scores differed significantly from ultra-low (10^th percentile) scorers on measures of affective intensity, depression, impulsiveness, abuse history, and attachment security.

Conclusion

STS-3 transformed scores at admission to the psychiatric hospital predict suicide attempts following discharge among the high-risk group of suicidal inpatients. Patients with high transformed scores appear to comprise two clinically distinct groups; an impulsive, affectively intense, fearfully attached group with high raw STS-3 scores and a low-impulsivity, low affect and low trauma-reporting group with low raw STS-3 scores. These groups may correspond to low-plan and planned suicide attempts, respectively, but this remains to be established by future research.     

长期住院老年精神疾病患者营养状况与认知功能的相关性研究

目的:了解长期住院老年精神疾病患者营养状况及与认知功能的相关性,为临床提供指导。方法:对住院3个月及以上的123例老年精神疾病患者采用简易精神状态检查量表(MMSE)评估认知功能,采用简易微型营养评定精简版(MNA-SF)评估营养状况,并采集一般资料、相关营养生化指标,应用Pearson相关分析MNA-SF评分与MMSE评分的相关性。结果:123例患者中,营养不良风险者67例(54.47%),营养不良者37例(30.08%),营养正常者19例(15.44%)。有认知障碍患者的营养不良发生率显著高于无认知障碍患者营养不良发生率(P<0.05),重度认知障碍者营养不良发生率显著高于轻、中度认知障碍者(P<0.05)。与无认知障碍者比较,中度、重度认知障碍者MNA-SF评分显著降低(P<0.05);与轻度、中度认知障碍者比较,重度认知障碍者MNA-SF评分显著降低(P<0.05)。营养不良者MMSE 6个认知领域评分和认知总评分均显著低于营养不良风险/正常者(P<0.05),Pearson相关分析显示:长期住院老年精神疾病患者MNA-SF评分与MMSE评分呈正相关(r=0.486, P=0.023<0.05)。结论:长期住院老年精神疾病患者营养不良发生率高,且与认知功能密切相关。临床部门需加强老年精神疾病患者,特别是有认知损害老人的营养关切。     

Childhood Asthma Management Pre- and Post-Incident Asthma Hospitalization

Many hospitalizations for asthma could potentially be avoided with appropriate management. The aim of this study was to analyze data on disease management of a paediatric population with a hospitalization for asthma. The study population comprised 6–17 year old subjects belonging to three local health units of the Lombardy Region, northern Italy. Regional administrative databases were used to collect data on: the number of children with an incident hospitalization for asthma during the 2004–2006 period, anti-asthma therapy, specialist visit referrals, and claims for spirometry, released in the 12 months before and after hospitalization. Each patient’s asthma management profile was compared with GINA guideline recommendations. Among the 183 hospitalized subjects, 101 (55%) received therapy before hospitalization and 82 (45%) did not. 10% did not receive any therapy either before or after hospital admission and in 13% the therapy was discontinued afterward. Based on GINA guidelines, asthma management adhered to recommendations only for 55% of subjects. Results may suggest that for half of hospitalized subjects, inaccurate diagnosis, under-treatment/scarce compliance with asthma guidelines by physicians, and/or scarce compliance to therapy by patients/their parents occurred. In all these cases, hospitalization would be a proxy indicator of preventable poor control of disease, rather than a proxy indicator of severity.     

Posterior Teeth Occlusion Associated with Cognitive Function in Nursing Home Older Residents: A Cross-Sectional Observational Study

Early detection and subsequent reduction of modifiable risk factors for cognitive decline is important for extending healthy life expectancy in the currently aging society. Although a recent increase in studies on the state or number of the teeth and cognitive function, few studies have focused on the association between posterior teeth occlusion necessary to maintain chewing function and cognitive function among older adults. This study examined the association between posterior teeth occlusion and cognitive function in nursing home older residents. In this cross-sectional study, 279 residents aged ≥60 years from eight nursing homes in Aso City, Japan participated in cognitive function and dental status assessments and completed a comprehensive questionnaire survey in 2014. Cognitive function was measured using a Mini-Mental State Examination (MMSE). Posterior teeth occlusion was assessed using a total number of functional tooth units (total-FTUs), depending on the number and location of the remaining natural and artificial teeth on implant-supported, fixed, and removable prostheses. Linear regression models were used to assess univariate and multivariate associations between total-FTUs and MMSE scores. Models were sequentially adjusted for demographic characteristics, number of natural teeth, socioeconomic status, health behaviors, comorbidities, physical function, and nutritional status. Among the 200 residents included in our analysis, mean MMSE scores and total-FTUs were 11.0 ± 8.6 and 9.3 ± 4.6, respectively. Higher total-FTUs were significantly associated with higher MMSE scores after adjustment for demographics and teeth number (B = 0.48, 95% confidence interval [CI] = 0.22–0.74). The association remained significant even after adjustment for all covariates (B = 0.25, 95% CI = 0.01–0.49). The current findings demonstrated that loss of posterior teeth occlusion was independently associated with cognitive decline in nursing home older residents in Japan. Maintenance and restoration of posterior teeth occlusion may be a preventive factor against cognitive decline in aged populations.     

Effectiveness of smoking-cessation interventions for urban hospital patients: study protocol for a randomized controlled trial

ABSTRACT: BACKGROUND: Hospitalization may be a particularly important time to promote smoking cessation, especially in the immediate post-discharge period. However, there are few studies to date that shed light on the most effective or cost-effective methods to provide post-discharge cessation treatment, especially among low-income populations and those with a heavy burden of mental illness and substance use disorders. METHODS: This randomized trial will compare the effectiveness and cost-effectiveness of two approaches to smoking cessation treatment among patients discharged from two urban public hospitals in New York City. During hospitalization, staff will be prompted to ask about smoking and to offer nicotine replacement therapy (NRT) on admission and at discharge. Subjects will be randomized on discharge to one of two arms: One arm will be proactive multi-session telephone counseling with motivational enhancement delivered by study staff, and the other will be a faxed or online referral to the New York State Quitline. The primary outcome is 30-day point-prevalence abstinence from smoking at 6-month follow-up post-discharge. We will also examine cost-effectiveness from a societal and a payer perspective, as well as explore subgroup analyses related to patients' location of hospitalization, race/ethnicity, immigrant status, and inpatient diagnosis. DISCUSSION: This study will explore issues of implementation feasibility in a post-hospitalization patient population, as well as add information about the effectiveness and cost-effectiveness of different strategies for designing smoking cessation programs for hospitalized patients.     

The influence of sunlight exposure on hospitalization in emergency psychiatry

Objective: Environmental conditions during early life may affect individual vulnerability to both physiological changes as well as psychiatric conditions, especially in those with a genetic susceptibility. Among all factors, sunlight exposure intensity has a crucial effect on affecting circadian functions high-risk individuals. A potential explanation of this relation is that excessive sunlight exposure is able to impair biological mechanisms, possibly through the dysregulation of serotonin and/or melatonin production/metabolism. The aim of this study was to evaluate the influence of excessive sunlight exposure in a sample of emergency psychiatry inpatients. Methods: All subjects were consecutively recruited from the Psychiatric Inpatient Unit of San Luigi Gonzaga Hospital, Orbassano (University of Turin, Italy) from September 2013 to August 2015. Socio-demographic and clinical characteristics were carefully collected. Results: We initially screened a sample of 900 patients; however, only 730 subjects voluntary accepted to participate in the study. Patients with admissions in spring/summer (a period in which daylight/darkness ratio is longer) showed a higher prevalence of involuntary admission, an earlier age at illness onset, a longer duration of hospitalization and admission for (hypo)manic episode. Conclusions: Excessive sunlight exposure may exert a fundamental role on psychopathological conditions presumably affecting biological vulnerability. A better understanding of its effect on the course of bipolar and other psychiatric disorders may assist in tailoring the adequate treatment for patients resulting in a shorter stay within hospitalized settings and a better treatment response.     

Recurrent psychiatric hospitalization.

Undue emphasis has been placed on rising rates of readmission to psychiatric facilities. After a decade of preoccupation with discharge rates, readmission statistics have been singled out in the last 15 years as the key factor for assessing hospital effectiveness. A study of a group of patients at high risk for recurrent hospitalization revealed that these patients were characterized more by features relating to environmental supports than by diagnosis. The operational definition for recurrent hospitalization (five or more admissions during the 2-year period preceding the latest admission) was effective in identifying this group; this is the first reported instance in which the definition has specified a certain number of admissions within a time-limited period. The findings of this study, as well as of an analysis of case histories and consumer opinion, led to the design of a pilot program for persons undergoing recurrent hospitalization. Readmission statistics are useless or misleading as measures of hospital effectiveness and efficiency; what matters is the way the former patients function in the community after discharge. Rather than simply trying to reduce the readmission rate psychiatric facilities should be examining the types of persons who are hospitalized recurrently to develop programs aimed at improving the functioning of these people in the community.     

长期住院精神障碍患者现况调查

目的:探讨长期住院精神障碍患者的现况及其影响因素。方法:采用自制调查问卷对2013年1月1日至7月1日我院慢性病科住院治疗2年以上的473例精神障碍患者进行调查分析。结果:长期住院患者中,男性比例高于女性,以精神分裂症患者居多,婚姻状况以未婚者居多;合并躯体疾病315例(66.60%),合并1种疾病者145例(30.66%),合并2种以上疾病者170例(35.94%),年龄与合并躯体疾病有关,70岁以上发生率最高;因精神病性症状反复发作滞留医院131例(27.70%),因家属无法对患者进行日常照顾、家属无法管理患者,担心危害、家庭经济困难、无接收对象而仍然滞留在医院342例(72.30%)。结论:精神障碍患者滞留医院除了因为病情慢性化,也有家庭、社会、经济等因素。发展社区精神卫生防治康复工作既能降低医疗成本,也有助于改善康复期患者的生活质量。     

Quantifying physical functional trajectory in hospitalized older adults using body worn inertial sensors

Acute medical illness requiring hospitalization usually is a critical event in the trajectory leading to disability in older adults. Functional decline frequently occurs during hospitalization, resulting in a loss of Independence in activities of daily living after discharge. The aim of the study was to assess the functional decline in different ADLs of hospitalized elderly patients in an Acute Care for Elderly (ACE) unit incorporating a body-worn inertial sensor and accompanying custom algorithms. 38 hospitalized older adults (age ≥ 75) were included. The patients completed different functional tasks, including a balance test, Gait Velocity Test (GVT), verbal and arithmetic dual-task gait, and a sit-to-stand ability test at admission and discharge. Movement-related parameters were acquired from a unique tri-axial inertial sensor unit. Maximal muscle strength and muscle power output endpoints were also assessed. The results indicated that significant improvements (p < 0.05) were found at discharge compared with the admission values for gait variability and spatiotemporal parameters in the 4- and 6-meter GVT. These significant gains were also obtained in the verbal GVT. In contrast, a significant reduction was found in the functional status measured with the Barthel Index scale. Regarding to the sit-to-stand ability, lower peak power was observed in the sit-to-stand phase of the task at discharge. In conclusion, inertial sensor unit and our custom, validated, algorithms represent a feasible tool for measuring and monitoring functional trajectory during hospitalization in older adults and they are sensitive to detect differences in movement pattern parameters in different ADLs such as walking and the ability to stand from a seated position.     

Glycemic Outcomes of Hospitalized Patients on Ambulatory Humulin-R U-500 Insulin

ObjectiveManaging hospitalized patients on ambulatory U-500 insulin is challenging because of limited guidance on how to safely adjust insulin doses during admission. We sought to evaluate glycemic outcomes in relation to inpatient insulin doses in patients receiving U-500 prior to hospitalization.MethodsRetrospective study of hospitalized patients on ambulatory U-500 seen consecutively from January 2015 to December 2019. Primary outcomes were inpatient hypoglycemia, hyperglycemia, and normoglycemia at different insulin dosages expressed as weight-based (unit/kg/d) inpatient total daily dose (TDD) and ratio of inpatient to outpatient TDD.ResultsWe identified 66 admissions of 46 unique patients. The median (interquartile range) body mass index was 41.0 kg/m² (35.1, 46.8), home TDD 212 units (120, 300), and home insulin dose 1.6 units/kg/d (1.1, 2.2). The median (interquartile range) inpatient insulin dose was 0.7 unit/kg/d (0.3, 1.0) and the ratio of inpatient to outpatient TDD was 0.4 (0.2, 0.8). Hyperglycemia persisted throughout the hospitalization. For the outcomes of hyperglycemia and normoglycemia, we found no association between increased levels of insulin dosages. For the outcome of hypoglycemia, significantly higher odds were observed when non-fasting patients received an inpatient TDD that was either > 40% of their home TDD or > 0.6 unit/kg/d of insulin.ConclusionPatients on ambulatory U-500 have significant hyperglycemia during admission. Inpatient insulin doses of 40% of home TDD or ≤ 0.6 unit/kg were not associated with increased hypoglycemia risk. Further prospective studies are needed to determine effective doses in these high-risk patients.     

Psychotic Illness in First-Time Mothers with No Previous Psychiatric Hospitalizations: A Population-Based Study

Background

Psychotic illness following childbirth is a relatively rare but severe condition with unexplained etiology. The aim of this study was to investigate the impact of maternal background characteristics and obstetric factors on the risk of postpartum psychosis, specifically among mothers with no previous psychiatric hospitalizations.

Methods and Findings

We investigated incidence rates and potential maternal and obstetric risk factors of psychoses after childbirth in a national cohort of women who were first-time mothers from 1983 through 2000 (n = 745,596). Proportional hazard regression models were used to estimate relative risks of psychoses during and after the first 90 d postpartum, among mothers without any previous psychiatric hospitalization and among all mothers. Within 90 d after delivery, 892 women (1.2 per 1,000 births; 4.84 per 1,000 person-years) were hospitalized due to psychoses and 436 of these (0.6 per 1,000 births; 2.38 per 1,000 person-years) had not previously been hospitalized for any psychiatric disorder. During follow-up after the 90 d postpartum period, the corresponding incidence rates per 1,000 person-years were reduced to 0.65 for all women and 0.49 for women not previously hospitalized. During (but not after) the first 90 d postpartum the risk of psychoses among women without any previous psychiatric hospitalization was independently affected by: maternal age (35 y or older versus 19 y or younger; hazard ratio 2.4, 95% confidence interval [CI] 1.2 to 4.7); high birth weight (≥ 4,500 g; hazard ratio 0.3, 95% CI 0.1 to 1.0); and diabetes (hazard ratio 0).

Conclusions

The incidence of psychotic illness peaks immediately following a first childbirth, and almost 50% of the cases are women without any previous psychiatric hospitalization. High maternal age increases the risk while diabetes and high birth weight are associated with reduced risk of first-onset psychoses, distinctly during the postpartum period.
