Choking deaths: the role of antipsychotic medication

Diagnostic Accuracy of Mann Assessment of Swallowing Ability for Predicting Dysphagia in Patients with Psychiatric Disorders

Dysphagia occurs in various diseases and constitutes a major concern in patients with psychiatric disorders. The Mann Assessment of Swallowing Ability (MASA) comprises 24 clinical parameters designed to identify swallowing disorders. One item in MASA, the "gag reflex", involves an unpleasant stimulus, which means that it is often omitted when the test is administered. The aims of this study were to determine the presence/absence of dysphagia in patients with psychiatric disorders using the MASA and determine its diagnostic accuracy when the gag reflex item was excluded in patients with psychiatric disorders. The study participants comprised patients admitted to a hospital psychiatric ward in whom dysphagia had been suspected based on oral intake status. The following items were determined: age, total MASA score (23 out of 24 items, giving a score out of 195 points), body mass index score, milligram equivalents of chlorpromazine, and the Food Intake Level Scale score. The patients were divided into two groups according to the presence or absence of swallowing problems as assessed by videoendoscopic or videofluoroscopic examination. The scores for each item investigated in the MASA, including the total score, were compared between the two groups. Receiver operating characteristic curve analysis was carried out to determine the optimum cut-off value. The total MASA score, which excluded the "gag reflex" item, was lower in the problematic swallowing group than in the non-problematic swallowing group. The MASA scores for cooperation, respiratory, dysphasia, tongue coordination, oral preparation, pharyngeal phase, and pharyngeal response tended to be lower in the problematic swallowing group. Furthermore, an optimum cut-off value of 169 points (sensitivity, 0.92; specificity, 0.68; likelihood ratio, 2.84) was identified. These results indicate that the cut-off MASA score is effective in screening for dysphagia, even when the "gag reflex" item is excluded.

Food choking incidents in the hospital: incidents, characteristics, effectiveness of interventions, and mortality and morbidity outcomes

AIM

Foreign body airway obstruction (FBAO) due to food can occur wherever people eat, including in hospitals. We characterized in-hospital FBAO incidents and their outcomes.

METHODS

We searched the Japan Council for Quality Health Care nationwide in-hospital adverse events database for relevant events from 1,549 institutions. We included all patients with FBAO incidents due to food in the hospital from January 2010 to June 2021 and collected data on the characteristics, interventions, and outcomes. FBAO from non-food materials were excluded. Our primary outcomes were mortality and morbidity from FBAO incidents.

RESULTS

We identified 300 patients who had a FBAO incident from food. The most common age group was 80 - 89 years old (32.3%, n = 97/300). One-half (50.0%, n = 150/300) were witnessed events. Suction was the most common first intervention (31.3%, n = 94/300) and resulted in successful removal of foreign body in 17.0% of cases (n = 16/94). Back blows (16.0%, n = 48/300) and abdominal thrusts (8.1%, n = 24/300) were less frequently performed as the first intervention and the success rates were 10.4% (n = 5/48) and 20.8% (n = 5/24), respectively. About one-third of the patients (31%, n = 93/300) died and 26.7% (n = 80/300) had a high potential of residual disability from the incidents.

CONCLUSION

FBAO from food in the hospital is an uncommon but life-threatening event. The majority of patients who suffered from the in-hospital FBAO incidents did not receive effective interventions initially and many of them died or suffered residual disability.

Schizophrenia, but not depression or bipolar affective disorder, adds additional risk of aspiration pneumonia among stroke survivors: A national cohort study in Taiwan

OBJECTIVE

Few studies have assessed the sex-specific and age-specific risk of aspiration pneumonia (AP) in patients with stroke and evaluated whether mental disorders may increase this risk. In this population-based cohort study, we investigated the sex-specific and age-specific risk of AP in association with stroke and the joint effects of stroke and mental disorders on the risk of AP.

METHODS

We included 23,288 patients with incident stroke admitted between 2005 and 2017 and 68,675 matched nonstroke controls. Information on mental disorders was obtained from medical claims data within the 3 years before the stroke incidence. Cox proportional hazards models considering death as a competing risk event were constructed to estimate the hazard ratio of AP incidence by the end of 2018 associated with stroke and selected mental disorders.

RESULTS

After ≤14 years of follow-up, AP incidence was higher in the patients with stroke than in the controls (11.30/1000 vs. 1.51/1000 person-years), representing a covariate-adjusted subdistribution hazard ratio (sHR) of 3.64, with no significant sex difference. The sHR significantly decreased with increasing age in both sexes. Stratified analyses indicated schizophrenia but not depression or bipolar affective disorder increased the risk of AP in the patients with stroke.

CONCLUSION

Compared with their corresponding counterparts, the patients with schizophrenia only, stroke only, and both stroke and schizophrenia had a significantly higher sHR of 4.01, 5.16, and 8.01, respectively. The risk of AP was higher in younger stroke patients than those older than 60 years. Moreover, schizophrenia was found to increase the risk of AP in patients with stroke.

Choking injuries: Associated factors and error-producing conditions among acute hospital patients in Japan

Choking can lead to mortality and residual impairments. This study aimed to determine the factors associated with choking among acute hospital patients and examine error-producing conditions to suggest choking-prevention policies. Among 36,364 cases reported by hospital staff at an acute university hospital from 2012 to 2018 were examined using a retrospective study, 35,440 were analysis as the number of cases analysed for the study. We used descriptive statistics to present patient characteristics and conducted univariable and multivariable logistic regression analyses to identify factors associated with choking. Additionally, we conducted content analysis (root cause analysis) to examine error-producing conditions and prevention policies. Sixty-eight cases were related to choking injuries; of these, 43 patients (63.2%) were male, and 38 (55.9%) were aged 65 years and older. Choking cases had a high percent of adverse outcomes involving residual impairment or death (n = 23, 33.8%). Mental illness (adjusted odds ratio [95% confidence interval]: 3.14 [1.39−7.08]), and hospitalisation in the general wards (adjusted odds ratio [95% confidence interval]: 3.13 [1.70−5.76]) were associated with an increased probability of choking. Error production was caused by food (n = 25, 36.8%) and medical devices or supplies (n = 13, 19.1%). Almost all contributory factors were associated with inadequate checking (n = 66, 97.1%) and misperception of risk (n = 65, 95.6%). Choking poses a highly significant burden on patients, and hospital administrators should minimise the risk of choking to prevent related injuries. Hospital administrators should provide training and education to their staff and develop adequate protocols and procedures to prevent choking.

Psychopathological aspects of dysphagia: a systematic review on correlations with eating disorders and other psychiatric conditions

BACKGROUND

The effect of psychopathology on swallowing ability tends to be an overlooked issue in the assessment of dysphagic patients, possibly overshadowed by the given prominence to organic pathologies and the difficulties on the management of these patients. In addition, it should also be kept in mind that a great number of psychotropic drugs can affect swallowing adding problematic clinical issues in this area. Despite this, assessment of dysphagia should be considered as an extremely important issue, due to its impact on basic symptomatology, course of illness and quality of life.

OBJECTIVE

This review aims to be an overview of relevant data on psychopathology associated with dysphagia and impairment of swallowing function.

MATERIALS AND METHODS

An extensive bibliographic search was carried out in different medical databases (PubMed and Psycharticles) to comprehensively identify the most relevant publications available on dysphagia in eating disorders published until December 2020, according to the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analysis) method. Research articles, either theoretical or empirical-based, published in peer-reviewed journals and in English language, were included. Case reports were also considered in the analysis when it was appropriate for completeness purposes. Titles and abstracts were reviewed according to the eligibility criteria.

RESULTS

In total, 260 published studies were identified and 40 were finally selected after removal of duplicates and relevance. Primarily we investigated the correlation between dysphagia and eating disorders, analysing the complex relationship between the two conditions. Then we provided an overview of the assessment of dysphagic symptoms in other psychiatric syndromes.

LIMITS

No exclusion criteria or statistical methods were applied nor was an assessment of study-level or outcome-level bias applicable for our purpose. The topic is vast and research bias could not be excluded; moreover, data available are heterogeneous and lacking systematic approach.

CONCLUSIONS

With this review, the authors want to provide an overview of the most considerable and clinically useful information about the topic, focusing on some key points to disentangle psychiatric components from the complexity of patient with dysphagia. It should be a relevant concern for all clinicians and should be always thoroughly assessed, considered its frequency in clinical practice and its implications in every kind of patients' morbidity, mortality and quality of life. Special attention should be paid to mentally ill patients, who might display complex and multiple comorbidities, as well as consequences of abnormal eating behaviours, occasionally exacerbated by psychotropic medications. More systematic studies are needed, while it seems clear that a multidisciplinary approach is pivotal in the assessment and management of dysphagic patients.

LEVEL OF EVIDENCE

Level I (evidence obtained from at least one properly designed randomized controlled trials; systematic reviews and meta-analyses; experimental studies).

Mealtime difficulties in adults with mental health conditions: an integrative review

BACKGROUND

Dysphagia and choking are highly prevalent in adults with mental health conditions. However, there is scant research considering the personal experience of dysphagia for this population.

AIMS

To understand the evidence-base for strategies to involve the patient in recognition, assessment and treatment of mealtime difficulties.

METHODS

This integrative review synthesised the literature on the experience of dysphagia in patients with mental health conditions. Patient consultation led to co-designed search terms and eligibility criteria for a systematic search of five scientific databases following Prisma guidance. Quality assessment of the eligible studies and reflexive thematic analysis were completed.

RESULTS

31 studies were included for review. These included case reports, literature reviews and cross-sectional studies. Quality of evidence was weak and no intervention studies were identified. There was scant detail regarding the personal experience of dysphagia or choking. Themes identified related to biomedical perspectives, influencing factors presented without context, and decision-making led by clinicians.

CONCLUSIONS

Guidance on mental healthcare calls attention to under-diagnosis of physical co-morbidities and advocates patient inclusion. However, the patient voice in this population is rarely described regarding dysphagia. Further inclusive research is indicated to explore the impact of dysphagia and choking, and implications for interventions and outcome measures.

Café coronary syndrome - case report and medicolegal implications

Café coronary syndrome is a term used to describe a sudden collapse of healthy subjects during meals in the absence of any sign of asphyxia, respiratory distress, or neurological symptoms. Risk factors are advanced age, poor dentition, alcohol intoxication, and dementia or psychiatric disorders. One of the main problems with this syndrome is that, even when witnessed, it is often confused with myocardial infarction due to the absence of asphyxia symptoms. This leads to misdiagnosis and potential delays in patients' treatment that can eventually have fatal outcomes. As a result of that, medico-legal litigation may arise. This paper presents a typical case of fatal café coronary syndrome misdiagnosed as a myocardial infarction. The legal authority that requested the autopsy asked about the potential professional negligence of the healthcare providers who took care of the patient. We discuss the clinical and medico-legal aspects of café coronary syndrome.

Disordered Eating among People with Schizophrenia Spectrum Disorders: A Systematic Review

Disordered eating, or abnormal eating behaviours that do not meet the criteria for an independent eating disorder, have been reported among people with schizophrenia. We aimed to systemati-cally review literature on disordered eating among people with schizophrenia spectrum disorder (SSD). Seven databases were systematically searched for studies that described the prevalence and correlates of disordered eating among patients with SSD from January 1984 to 15 February 2021. Qualitative analysis was performed using the National Institutes of Health scales. Of 5504 records identified, 31 studies involving 471,159 subjects were included in the systematic review. The ma-jority of studies (17) rated fair on qualitative analysis and included more men, and participants in their 30s and 40s, on antipsychotics. The commonest limitations include lack of sample size or power calculations, poor sample description, not using valid tools, or not adjusting for con-founders. The reported rates were 4.4% to 45% for binge eating, 16.1% to 64%, for food craving, 27% to 60.6% for food addiction, and 4% to 30% for night eating. Positive associations were re-ported for binge eating with antipsychotic use and female gender, between food craving and weight gain, between food addiction and increased dietary intake, and between disordered eating and female gender, mood and psychotic symptoms. Reported rates for disordered eating among people with SSD are higher than those in the general population. We will discuss the clinical, treatment and research implications of our findings.

Nutrition risk screening methods for adults living with severe mental illness: A scoping review

AIM

Adults living with severe mental illness experience a greater burden of physical comorbidities and earlier mortality than the general population. Malnutrition, overnutrition, dysphagia, constipation and disordered eating have been observed in this population and can lead to poor nutritional status. Early identification of such conditions may reduce their impact on functional status, quality of life and health outcomes. This scoping review aimed to identify all nutrition risk screening methods published in English internationally for use with adults living with severe mental illness and ascertain which, if any, were validated for the target population.

METHODS

A four-step search strategy was used to search six electronic databases and grey literature, from inception to April 2020, for articles reporting nutrition risk screening methods used in this population. Information on the content and validity of screening methods was extracted and analysed by three independent reviewers.

RESULTS

Seventeen nutrition risk screening methods were identified, of which three were validated within a population of adults with severe mental illness. One screening method was found for both malnutrition and dysphagia risk, respectively, and three for constipation risk. No single method was found for overnutrition. Eleven screening methods were identified for disordered eating risk, of which two were validated for the target population.

CONCLUSIONS

Nutrition risk screening methods and their validation in adults living with severe mental illness are inadequately researched. This scoping review highlights the need for future research to develop new or validate existing screening methods specifically for the target population.

Changes in Psychotropic Prescribing for Patients With Dementia, 2014-2016: Potential implications for Pharmacists

OBJECTIVE

To assess changes in psychotropic pharmacotherapy for patients with dementia over a three-year period.<br/> SETTING: National Ambulatory Medical Care Survey, physician office visits from 2014 to 2016.<br/> PRACTICE DESCRIPTION: Retrospective analysis of publicly available, nationally representative data on patient characteristics; diagnoses, including comorbidities; and treatments, including medications. Included were patients with a diagnosis of Alzheimer's disease or dementia who were 18 years of age or older. No sample exclusions were applied.<br/> INTERVENTION: Time period, comparing calendar year (CY) 2014 versus the calendar years 2015 and 2016 using Pearson chi-square tests.<br/> MAIN OUTCOME MEASURE(S): Prescribing rates of psychotropic medications, grouped by therapy class.<br/> RESULTS: The sample included 647 patients (337 in 2014 and 310 in 2015-2016). A majority (69.5%) of the patients were 75 years of age or older; 62.4% were female. Prescribing rates remained relatively stable for antipsychotics (15.1% in 2014 to 12.9% in 2015-16; P = 0.607); antidepressants (35.0% to 27.7%; P = 0.263); acetylcholinesterase inhibitors (38.6% to 33.9%; P = 0.446); and memantine (19.4% to 16.8%; P = 0.551). Significant increases were noted for sedatives (11.9% to 21.7%; P = 0.037) and anticonvulsants (10.0% to 27.6%, P = 0.001).<br/> CONCLUSION: Clinically significant increases in the prescribing of anticonvulsants and sedatives suggest the possibility that these agents are used to combat behavioral and psychological symptoms of dementia in patients with dementia. Further research is required to assess the rationale, efficacy, and safety of these uses.

Dying for a Meal: An Integrative Review of Characteristics of Choking Incidents and Recommendations to Prevent Fatal and Nonfatal Choking Across Populations

Purpose The purpose of this study was to conduct an integrative review of original research, across adult populations relating to fatal or nonfatal choking on food, to understand ways to respond to and prevent choking incidents. Method Four scientific databases (CINAHL, Medline, Web of Science, and EMBASE) were searched for original peer-reviewed research relating to fatal or nonfatal choking on foods. Data were extracted on study characteristics; factors leading up to, events at the time of, and actions taken after the choking incident; and impacts of choking incidents. An integrative review of the findings across studies identified several risk factors and recommendations to reduce the risk of choking. Results In total, 52 studies met the criteria for inclusion in this review, of which 31 were quantitative, 17 were qualitative, and 4 were of a mixed methods design. Studies reported the observations and narratives of bystanders or researchers, or else were large-scale autopsy studies, and included both the general public and people at risk of dysphagia. A range of food types were involved, and several actions were reported in response to food choking. Strategies to reduce the risk of choking were identified in the studies and are presented in 5 main categories. Conclusions Factors leading up to choking incidents extend well beyond the individual to the environment for mealtimes; the provision of appropriate mealtime assistance and oral care; and regular monitoring of general health, oral health, and medications. Bystanders' increased awareness and knowledge of how to respond to choking are vital. The results of this review could be used to inform service policy and training, for individuals at risk of choking, the people who support them, and the general public. Further research is needed to explore choking prevention and airway protection in individuals with dysphagia. Supplemental Material https://doi.org/10.23641/asha.8121131.

A comprehensive review of swallowing difficulties and dysphagia associated with antipsychotics in adults

INTRODUCTION

This is a comprehensive review of antipsychotic (AP)-induced dysphagia and its complications: choking and pneumonia. Areas covered: Four PubMed searches were completed in 2018. The limited literature includes: 1) 45 case reports of AP-induced dysphagia with pharmacological mechanisms, 2) a systematic review of APs as a risk factor for dysphagia, 3) reviews suggesting adult patients with intellectual disability (ID) and dementia are prone to dysphagia (APs are a risk factor among multiple others), 4) studies of the increased risk of choking in patients with mental illness (APs are a contributing factor), 5) naturalistic pneumonia studies suggesting that pneumonia may contribute to AP-increased death in dementia, and 6) naturalistic studies suggesting that pneumonia may be a major cause of morbidity and mortality in clozapine patients. Expert commentary: The 2005 Food and Drug Administration requirement that package inserts warn of AP-induced dysphagia jumpstarted this area, but current studies are limited by: 1) its naturalistic nature, 2) the lack of dysphagia studies of patients with IDs and dementia on APs, and 3) the assumed indirect association between dysphagia with choking and pneumonia. Future clozapine studies on pneumonia, if they lead to a package insert warning, may have high potential to save lives.

Risk factors and nursing strategies to manage choking in adults with mental illness: a systematic review protocol

The review objectives are:Specifically, this review seeks to answer the following questions.

Swallowing Disorders in Schizophrenia

Disorders of swallowing are poorly characterized but quite common in schizophrenia. They are a source of considerable morbidity and mortality in this population, generally as a result of either acute asphyxia from airway obstruction or more insidious aspiration and pneumonia. The death rate from acute asphyxia may be as high as one hundred times that of the general population. Most swallowing disorders in schizophrenia seem to fall into one of two categories, changes in eating and swallowing due to the illness itself and changes related to psychotropic medications. Behavioral changes related to the illness are poorly understood and often involve eating too quickly or taking inappropriately large boluses of food. Iatrogenic problems are mostly related to drug-induced extrapyramidal side effects, including drug-induced parkinsonism, dystonia, and tardive dyskinesia, but may also include xerostomia, sialorrhea, and changes related to sedation. This paper will provide an overview of common swallowing problems encountered in patients with schizophrenia, their pathophysiology, and management. While there is a scarcity of quality evidence in the literature, a thorough history and examination will generally elucidate the predominant problem or problems, often leading to effective management strategies.

Impact of FDA Black Box Warning on Psychotropic Drug Use in Noninstitutionalized Elderly Patients Diagnosed With Dementia

Background:

The study seeks to investigate the impact of Food and Drug Administration's black box warning (BBW) on the use of atypical antipsychotics (AAP) and nonantipsychotic psychotropic alternatives in noninstitutionalized elderly population diagnosed with dementia.

Method:

The Medical Expenditure Panel Survey (2004 through 2007) was utilized as the data source. Medication use in elderly patients (≥65 years) was defined as taking at least 1 medication for dementia. We performed a statistical comparison of prewarning (2004-2005) and postwarning (2006-2007) periods with respect to AAP and nonantipsychotic psychotropic use to examine the impact of labeling changes.

Results:

A bivariate analysis did not yield statistically significant change in either the AAP or nonantipsychotic psychotropic use, pre- versus postwarning. However, multivariate logistic-regression analyses revealed greater odds for antidementia (odds ratio [OR] = 1.976, P = .0195) and benzodiazepine (OR = 3.046, P = .0227) medication use in postwarning period compared to the prewarning period.

Conclusion:

The regulatory warnings and labeling changes regarding off-label use of AAPs in dementia treatment showed minimal impact on their actual use in noninstitutionalized populations. A corresponding increase in the use of nonantipsychotic psychotropics explains that BBW might have resulted in a compensatory shift in favor of benzodiazepines and antidementia medications. Additional research should be conducted to examine the long-term impact of BBW on antipsychotic prescribing changes.

A needs analysis for the provision of a speech and language therapy service to adults with mental health disorders

Objectives: To examine a sample of adults with mental health disorders attending at an area psychiatric service, for the presence of impairments in language, communication and swallowing, using a test battery administered by speech and language therapists.

Method: The study surveyed a randomly selected sample (n = 60) of patients from an acute psychiatric inpatient unit and associated community services, using several standardised measures of language, communication and swallowing.

Results: On this test battery, over 80% (50/60) of subjects studied demonstrated impairment in language; while over 60% (37/60) presented with impairment in communication and discourse. Over 30% (18/58) of subjects assessed showed some impairment in swallowing.

Conclusion: Use of this test battery confirmed the presence of language, communication and swallowing impairments in many patients in this sample of attenders at a general psychiatry service. We suggest that this study provides evidence for a (currently unmet) need for specialist speech and language therapy assessment and support among this patient population.

Association of antidepressant and atypical antipsychotic use with cardiovascular events and mortality in a veteran population

STUDY OBJECTIVES

To determine the patterns of antidepressant and atypical antipsychotic use in a veteran population with depression, and to determine if an association exists between specific antidepressant classes and atypical antipsychotics and the occurrence of cardiovascular events and all-cause mortality.

DESIGN

Retrospective, cross-sectional study.

SETTING

Primary care clinic at a Veterans Affairs hospital.

PATIENTS

A total of 1136 patients diagnosed with depression who were receiving antidepressant monotherapy (664 patients) or no antidepressant therapy (472 patients [controls]) between June 2009 and December 2010.

MEASUREMENTS AND MAIN RESULTS

Data on patient demographics, disease diagnoses, laboratory data, and drug therapy profiles were collected through medical record review. Of the 1136 patients, the mean patient age was 61 years, 90% were men, and 77% were smokers. Mean body mass index was 30.4 kg/m(2) , blood pressure 126/73 mm Hg, hemoglobin A1c 6%, low-density lipoprotein cholesterol level 106.7 mg/dl, and Framingham score 17. Patients receiving antidepressant monotherapy were grouped according to antidepressant class; selective serotonin reuptake inhibitors (SSRIs) were most common. Concomitant use of atypical antipsychotics was more common with the serotonin-norepinephrine reuptake inhibitor (venlafaxine), SSRI, and serotonin receptor antagonist (trazodone) classes (p=0.0067). After adjusting for demographics, concomitant drugs, and comorbidities, SSRI use was significantly associated with lower all-cause mortality (odds ratio [OR] 0.37, 95% confidence interval [CI] 0.19-0.71, p=0.0028). Notably, noradrenergic and specific serotonergic antidepressant (mirtazapine) use was significantly associated with higher prevalence of heart failure (OR 3.26, 95% CI 1.029-10.38, p=0.0445). Use of atypical antipsychotics was significantly associated with a higher prevalence of cerebrovascular events (OR 2.23, 95% CI 1.29-3.83, p=0.0036) and all-cause mortality (OR 2.05, 95% CI 1.03-4.1, p=0.04).

CONCLUSION

Our results favor treatment of depression with SSRIs among patients at increased cardiovascular risk due to the potential mortality benefit of this class of drugs. Atypical antipsychotics should be used with caution in the elderly population. Mirtazapine use in patients with heart failure and depression deserves further investigation.

Adverse events in elderly users of antipsychotic pharmacotherapy in the province of Manitoba: a retrospective cohort study

BACKGROUND

Antipsychotic medications have been widely used in elderly patients for treatment of a variety of diagnoses. The aim of our study was to compare the incidence of cerebrovascular and cardiac events as well as mortality in elderly persons treated with second-generation antipsychotics (SGAs) with that of elderly persons treated with conventional first-generation agents (FGAs) in the province of Manitoba.

METHODS

A population-based retrospective cohort study of all residents of Manitoba aged 65 and older, who were dispensed antipsychotic medications for the first time during the period from April 1, 2000, to March 31, 2007, was conducted using Manitoba Health administrative databases. Cox proportional hazards models were used to compare risks of adverse events in FGA and SGA users.

RESULTS

After controlling for potential confounders (demographics, comorbidity, and medication use), SGA use was not associated with a significantly greater risk of cerebrovascular events, cardiac arrhythmia, and congestive heart failure compared to FGA use (adjusted hazard ratios [HR], respectively: 1.136; 95% CI, 0.961-1.344; 0.865; 95% CI, 0.336-2.232; 1.127, 95% CI, 0.902-1.409). Second-generation antipsychotics users were found to be at a lower risk of mortality (adjusted HR, 0.683; 95% CI, 0.577-0.809), but at a higher risk of myocardial infarction (adjusted HR, 1.614; 95% CI, 1.024-2.543) compared to FGA users.

CONCLUSIONS

Among elderly users of antipsychotic medications, the risk of cerebrovascular events, cardiac arrhythmia, and congestive heart failure was similar in FGA and SGA users. Whereas SGA users were at a higher risk of nonfatal myocardial infarction, the use of FGAs was associated with an increased risk of death. Antipsychotic pharmacotherapy in older persons needs to be chosen with careful consideration of all risks and benefits.

Psychiatric patients are at increased risk of falling and choking

Acutely ill psychiatric patients experience symptoms and take medications that increase their risk of both falling and choking; however, nurses and other caregivers may not be keenly aware of these risks. This article will provide a brief review of the literature related to risk factors for falls and choking and interventions to prevent falls and choking. Increased education for nursing students and staff employed at inpatient psychiatric units has the potential to reduce both incidence and injuries related to falls and choking.

Antipsychotics and mortality in Parkinsonism

BACKGROUND

: The use of antipsychotic medications is associated with an increased risk of death in older adults with dementia. The risk of death in patients with preexisting parkinsonism who receive antipsychotic drugs is not known.

METHODS

: Using a nested case-control design, we examined the risk of death within 30 days of newly starting antipsychotic medications among people with Parkinsonism aged 70 years and older in Ontario, Canada. Data were obtained from Ontario's healthcare administrative databases.

RESULTS

: Among 5,391 individuals with parkinsonism who died during the study period (2002-2008) and a matched comparison group of 25,937 who were still alive, individuals exposed to atypical antipsychotic drugs had a higher risk of death (unadjusted odds ratio [OR] = 2.8, 95% CI: 2.1-3.8, adjusted OR: 2.0, 95% CI: 1.4-2.7). Results were similar for quetiapine use compared with no antipsychotic use (unadjusted OR: 2.5, 95% CI: 1.6-4.0, adjusted OR = 1.8, 95% CI: 1.1-3.0). Typical antipsychotics were associated with an increased odds of death compared with atypical antipsychotics (unadjusted OR = 2.4, 95% CI 1.1-5.2, adjusted OR = 2.4, 95% CI: 1.1-5.7).

CONCLUSIONS

: Individuals with parkinsonism who are newly prescribed antipsychotic medications have a higher risk of death within 30 days than those who do not start these medications. Although it is not possible to establish causality, the results suggest an increased risk. It is important to be vigilant for accompanying serious medical conditions that may increase mortality in individuals requiring treatment with antipsychotics and to consider alternative approaches to treating psychosis, agitation, and aggression in this population.

Dysphagia is a common and serious problem for adults with mental illness: a systematic review. Dysphagia. 2012;27:124-137. [PMID: 22120763 DOI: 10.1007/s00455-011-9378-5]

Adults with mental illness may experience a higher incidence of dysphagia and choking due to factors such as medication side effects and behavioural abnormalities. The aim of this study was to determine the frequency of dysphagia and the most effective interventions for this population. Studies published up to August 2010 were sought via a comprehensive electronic database search (CINAHL, PsycINFO, MEDLINE, PubMed, Cochrane, and Embase). Studies reporting dysphagia frequency or dysphagia intervention outcomes in adults with mental illness were included. Two reviewers independently assessed study eligibility and quality, and the results were synthesised descriptively. Ten studies were identified, each describing dysphagia frequency or death due to choking asphyxiation. No studies evaluating intervention effectiveness were identified. Study quality was limited by subjective assessment of outcomes. Six studies presented dysphagia frequencies ranging from 9 to 42% in varying subgroups. Four studies presented the frequency of choking asphyxiation death, including a large survey that concluded that adults with organic mental illness were 43 times more likely to die of this cause than the general population. Dysphagia is a common and significant cause of morbidity and mortality in adults with mental illness and our review found that there is a lack of studies evaluating the effectiveness of intervention techniques.

The Impact of Prescribed Medication on Swallowing: An Overview

Dysphagia clinicians are aware that best practices guidelines recommend a medications review as part of the assessment process. This article aims to review the literature to date regarding the impact that medications may have on the physiology of swallowing. It is important to consider the side effects of all medications, not only medications listing swallowing difficulties as a known side effect. Medications that impact upon arousal, awareness, and xerostomia should also be considered as part of a comprehensive dysphagia evaluation. Speech-language pathologists should consider the pharmacist an integral dysphagia team member and a valuable resource.

Choking incidents among psychiatric inpatients: a retrospective study in Chutung Veterans General Hospital

BACKGROUND

Choking incidents have long been recognized as a cause of death in people with mental illness. This study attempted to determine the rate of choking incidents and deaths among psychiatric inpatients and identify the risk factors associated with choking incidents. Some preventive measures are also suggested.

METHODS

All choking incidents recorded over 3 years in 3 psychiatric wards of Chutung Veterans General Hospital (total of 210 beds) were retrospectively analyzed for demographic variables, psychiatric and medical diagnoses, and drug therapy at the time of the incidents.

RESULTS

During the 3-year period, 16 incidents were recorded, involving 11 patients at a rate of 1 incident every 451.4 months of hospitalization per person. Men were 3 times more likely to experience choking incidents than women, and the mean age of choking patients was higher than that of all patients (59.7 vs. 44.4 years). Among the 16 incidents, 3 fatal cases were noted, giving an annual choking death rate of 5.05 per 1,000 persons hospitalized. A high re-choking rate of up to 40.0% was noted, and patients with organic mental disorder had 3.4 times the choking incidence of all patients. The mean antipsychotic dosage of the choking cases was similar to that of all inpatients, but the mean hypnotic dosage of the fatal choking cases was significantly higher. Up to 62.5% of the choking accidents occurred at breakfast, and mantou (a type of steamed bun) was the most common food (9/16) that resulted in the accidents. Of the 11 patients, 9 were rated as "poor" or "very poor" with regard to self-care before the accidents.

CONCLUSION

Compared with studies in Western psychiatric inpatients, we have a lower choking incident rate but higher death rate due to choking. We found that older age, male sex, higher dosage of hypnotics, previous choking attacks, organic mental disorder, poor self-care, breakfast time and mantou were possible risk factors associated with choking, in which older age, poor self-care, and higher dosage of hypnotics for fatal cases were statistically significant.

Prescription drugs and their effects on swallowing

The impact of medications on the physiology of swallowing has received much attention in dysphagia literature. This article reviews the potential effects of medications commonly prescribed in an adult continuing care and rehabilitation facility on swallowing. An audit of medications prescribed to 153 adults accessing age-related respiratory, neurology, and learning disability services was performed. This was followed by an investigation of relevant sources to identify the potential side effects of these medications. One side effect, namely, xerostomia, which our investigations revealed could be a side effect of 24.8% of the medications used at our institution, was further investigated. The prevalence of xerostomia was then investigated in a randomly selected sample of ten subjects whose dysphagia had been confirmed by videofluoroscopy. It was found that six of the ten dysphagic clients displayed xerostomia. Review of the medications of these ten subjects indicated that all were using from three to nine drugs that could cause xerostomia. This article highlights the need for health-care professionals to consider the potential effects of these medications on swallowing and, indeed, the general presentation of clients.

Pericial analysis of a dental element found inside food used for human consumption

The field of forensic dentistry embodies the human identification in a lot of conditions. A case is described when a tooth-like object was found in a pork sausage. A lawsuit was filed against the food company and the possible dental element was analysed. The tests used to analyze the case were: scanning electronic microscopic exam, radiographic exam and compared anatomy. The results confirmed that the object found in the sausage pack was a dental element from an adult pig; which had the potential for problems like asphyxia or contamination. The case illustrates one facet of forensic dentistry in Brazil.

Physical illness and schizophrenia: a review of the literature

OBJECTIVE

The lifespan of people with schizophrenia is shortened compared to the general population. We reviewed the literature on comorbid physical diseases in schizophrenia to provide a basis for initiatives to fight this unacceptable situation.

METHOD

We searched MEDLINE (1966 - May 2006) combining the MeSH term of schizophrenia with the 23 MeSH terms of general physical disease categories to identify relevant epidemiological studies.

RESULTS

A total of 44 202 abstracts were screened. People with schizophrenia have higher prevalences of HIV infection and hepatitis, osteoporosis, altered pain sensitivity, sexual dysfunction, obstetric complications, cardiovascular diseases, overweight, diabetes, dental problems, and polydipsia than the general population. Rheumatoid arthritis and cancer may occur less frequently than in the general population. Eighty-six per cent of the studies came from industrialized countries limiting the generalizability of the findings.

CONCLUSION

The increased frequency of physical diseases in schizophrenia might be on account of factors related to schizophrenia and its treatment, but undoubtedly also results from the unsatisfactory organization of health services, from the attitudes of medical doctors, and the social stigma ascribed to the schizophrenic patients.

Contemporary management of aggression in an inner city mental health service

OBJECTIVES

From 2002 to mid 2003, Royal Brisbane and Women's Hospital Mental Health experienced increased patient - staff aggression and staff injury which resulted in staff conflict and recruitment difficulties. Strategies introduced to reduce the frequency and impact of aggression in the mental health service were evaluated.

METHOD

By mid 2003, incident data indicated increasing aggressive incidents. Based on this, an aggression management strategy was developed which included improved staff communication, new acute pharmacological treatment protocols, mandatory staff aggression management training, personal alarms and aggression risk assessment tools.

RESULTS

Following the introduction of the strategy in early 2004, there was a reduction of 40% in aggressive incidents and a 56% reduction in staff injuries in 2005 compared to 2003 levels. A more assertive approach to tranquillisation was not associated with an increased adverse event rate for patients.

CONCLUSIONS

A co-ordinated strategy can contain and reduce aggressive incidents in acute inpatient mental health settings. These strategies are transferable to other health settings including Emergency Departments.

An unusual cause of chronic cough. Foreign body aspiration

Foreign body aspiration (FBA) is a serious medical problem, causing thousands of deaths nationally each year. Clinical presentations range from acute suffocation and death to chronic and subtle respiratory symptoms. Although FBA is more common in children, adult patients are also at risk. We present a classic case of FBA in an adult male with a history of alcohol abuse and chronic cough.

Café coronary syndrome-fatal choking on food: an autopsy approach

To examine the characteristic features of fatal food asphyxia and to develop an autopsy approach to such cases a retrospective study of autopsy files was undertaken at Forensic Science SA (Adelaide, Australia) over a 10 year period from 1993 to 2002 for all cases of food asphyxia/café coronary syndrome. Forty-four cases were identified (M;F=21:23), with one infant (11 mths) and 43 adults (30-96 yrs; mean 68.9 yrs), with a preponderance of victims (57%) aged between 71 and 90 yrs. Deaths occurred in nursing homes (N=22) cases, at home (N=11) and in restaurants (N=4). Twenty-seven of the victims (61%) had histories of neurological or psychiatric disorders such as dementia (N=8), schizophrenia (N=6), Alzheimer disease (N=4), atherosclerotic cerebrovascular disease (N=4), mental impairment (N=2), multiple sclerosis (N=1), Parkinson disease (N=1) and obsessive-compulsive disorder (N=1). Twenty-seven cases (61%) were described as either edentulous or having significant numbers of teeth missing. Toxicological evaluation of blood revealed alcohol and a variety of psychotropic prescription medications in 19 cases. Sudden collapse during or shortly after a meal should always raise the possibility of café coronary and the autopsy examination should not only attempt to demonstrate airway occlusion by a bolus of food, but also to identify or exclude underlying neurological disease. Such cases may raise issues concerning adequacy of care and appropriateness of medication. The diagnosis of café coronary syndrome can only be made with confidence after the clinical history and circumstances of death have been clearly established, impacted material has been demonstrated in the airway at autopsy (or recorded by those attempting resuscitation), risk factors have been identified and other possible causes of death have been excluded.
