Life-threatening bronchospasm induced by an angiotensin-converting enzyme inhibitor in a chronically ventilated patient: Diagnostic pitfalls and literature review.

Cough- and asthma-like symptoms are common adverse reactions to angiotensin-converting enzyme inhibitors (ACEi). However, attributing these symptoms to the use of ACEi might be masked by clinical confounders. We report a 68-year-old female residing in a long-term acute-care facility for patients requiring prolonged invasive mechanical ventilation treated for years with ACEi. Daily reversible bouts of life-threatening severe bronchospasm gradually developed over 6 weeks and abruptly resolved following the cessation of ACEi treatment. The late appearance of bronchospasm and the unique clinical setup of chronic invasive ventilation in a patient with smoking-related chronic obstructive lung disease are among the principal confounders that delay the identification of the causative association between ACEi and respiratory compromise. Chronic positive pressure ventilation may also conceal small airway reactivity and obstruction, similar to auto-positive end-expiratory pressure (auto-PEEP). Conceivably, angiotensin receptor blockers should be preferred over ACEi in such patients.

Cognitive biases and moral characteristics of healthcare workers and their treatment approach for persons with advanced dementia in acute care settings.

Introduction: Palliative care (PC) delivery for persons with advanced dementia (AD) remains low, particularly in acute-care settings. Studies have shown that cognitive biases and moral characteristics can influence patient care through their effect on the thinking patterns of healthcare workers (HCWs). This study aimed to determine whether cognitive biases, including representativeness, availability, and anchoring, are associated with treatment approaches, ranging from palliative to aggressive care in acute medical situations, for persons with AD. Methods: Three hundred fifteen HCWs participated in this study: 159 physicians and 156 nurses from medical and surgical wards in two hospitals. The following questionnaires were administered: a socio-demographic questionnaire; the Moral Sensitivity Questionnaire; the Professional Moral Courage Scale; a case scenario of a person with AD presenting with pneumonia, with six possible interventions ranging from PC to aggressive care (referring to life-prolonging interventions), each given a score from (-1) (palliative) to 3 (aggressive), the sum of which is the "Treatment Approach Score;" and 12 items assessing perceptions regarding PC for dementia. Those items, the moral scores, and professional orientation (medical/surgical) were classified into the three cognitive biases. Results: The following aspects of cognitive biases were associated with the Treatment Approach Score: representativeness-agreement with the definition of dementia as a terminal disease and appropriateness of PC for dementia; availability-perceived organizational support for PC decisions, apprehension regarding response to PC decisions by seniors or family, and apprehension regarding a lawsuit following PC; and anchoring-perceived PC appropriateness by colleagues, comfort with end-of-life conversations, guilt feelings following the death of a patient, stress, and avoidance accompanying care. No association was found between moral characteristics and the treatment approach. In a multivariate analysis, the predictors of the care approach were: guilt feelings about the death of a patient, apprehension regarding senior-level response, and PC appropriateness for dementia. Conclusion: Cognitive biases were associated with the care decisions for persons with AD in acute medical conditions. These findings provide insight into the potential effects of cognitive biases on clinical decisions, which may explain the disparity between treatment guidelines and the deficiency in the implementation of palliation for this population.

Interprofessional palliative and end-of-life education: short-term and long-term outcomes - mixed-methods analysis.

ObjectiveInterprofessional care is integral to end-of-life (EOL) and palliative care (PC) and may be suited for EOL and PC education.We evaluate the impact of an interprofessional EOL care curriculum on participants, during the course, on completion and 4 years laterusing quantitative (questionnaires) and qualitative (open-ended questions and interviews) methods.The course included 14 fifth and sixth-year medical students, 9 social work students and 7 nursing students enrolled in master's degree programmes. Seventeen participants completed questionnaires 4 years later and eight participated in interviews.On postcourse questionnaires, participants attributed high value to interprofessional education (IPE) (4.77/5±0.50 on a Likert scale). Four years later, participants reported that IPE impacted their professional (3.65/5±1.11) and personal lives (3.94/5±1.09) and found PC IPE important (4.88/5±0.33).Conventional content analysis showed that the course enabled discussion of death and dying and provided an opportunity for a personal-emotional journey. It offered an approach to EOL care and an opportunity to experience interprofessional teamwork at the EOL resulting in behavioural change.Interprofessional EOL education resulted in meaningful and lasting self-reported personal and professional behavioural outcomes.

Prolonged mechanical ventilation and caregiver strain: Home vs. long-term care facility.

OBJECTIVE: The number of patients treated with prolonged mechanical ventilation (PMV) is steadily rising. Traditionally treated within specialized long-term care facilities (LTCFs), healthcare providers are increasingly promoting homecare as a technologically safe, humane, and cheaper alternative. Little is known concerning their informal caregivers (ICGs), despite their crucial role in facilitating care. This study examines caregiver strain among the primary ICG of PMV patients treated at home vs. LTCF. METHOD: This study was an observational cross-sectional study. The study enrolled 120/123 PMV patients ≥18 years within the study region (46 treated with homecare/74 treated at the LTCF) and 106 ICGs (34 ICGs/46 homecare patients and 72 ICGs/74 LTCF patients). Caregiver assessment included the 13-item Modified Caregiver Strain Index (Mod CSI) (0-26 maximum); patient assessment included symptom burden (the revised Edmonton Symptom Assessment System). RESULTS: The mean age of ICGs was 58.9 years old; 60.4% were females; 82.1% were married; 29.2% were patient's spouses; and 40.6% were patient's children. The total Mod CSI was 13.58 (SD 6.52) and similar between home vs. LTCF (14.30 SD 7.50 vs. 13.26 SD 6.03, p = 0.50), or communicative vs. non-communicative patients (13.50 SD 7.12 vs. 13.64 SD 6.04, p = 0.93). Hierarchical analysis identified three clusters of caregiver strain, with ICGs at home vs. LTCF reporting significantly lower mood strain, higher burden, and similar levels of lifestyle disturbance. In adjusted models, homecare was significantly associated with reduced mood strain and increased burden, while increased patient symptomatology was significantly associated with total strain, mood, and burden strain clusters. SIGNIFICANCE OF RESULTS: Recognizing the different patterns of caregiver strain at home or LTCF is a prerequisite for addressing their palliative care needs and improving the wellbeing and resilience of informal caregivers, who often play a critical role in deciding whether to treat the PMV patient at home or LTCF.

A 66-Year-Old Woman with Achondroplasia and Quadriparesis with an Ovarian Cyst Erroneously Diagnosed as Urinary Retention by an Automated Bladder Scan.

BACKGROUND Automated bladder scanning has become a principal tool in the assessment and management of chronically debilitated patients residing in skilled nursing facilities, hospices, and acute inpatient settings. To a large extent, the bladder scan, generally performed by nursing staff, has replaced physical examination while addressing the differential diagnoses of anuria or voiding disturbances that require consideration of urinary catheterization. Health care providers can quickly master this easily performed technique, and currently, due to confidence in the bladder scan finding, physical examination with suprapubic palpation and percussion may be carelessly omitted. The case description presented here illustrates how not performing a physical examination can lead to misdiagnosis caused by misinterpretation of bladder scan findings. CASE REPORT A 66-year-old, quadriparetic, chronically ventilated female patient with achondroplasia underwent repeated hospital referrals and bladder catheterizations for presumed flaccid, neurogenic bladder with urinary retention. This postulated diagnosis was based on occasional reports of urinary catheter obstruction as well as on automated bladder scanning indicating a markedly distended bladder. However, the bladder could not be drained by insertion of urinary catheters. Eventually, a proper physical examination excluded the presence of suprapubic fullness compatible with distended bladder and contradicting bladder scan findings, prompting re-examining an overlooked evaluation of computed tomography that reported a huge ovarian cyst. The patient was found to have intact voiding capabilities and is now weaned from the catheter. CONCLUSIONS This case and the literature review underscore drawbacks in automated bladder scanning. This technique should be used as an adjunctive measure rather than a replacement for a physical examination in the evaluation of voiding disturbances, especially when there are discrepancies between bladder scan findings and the volume of urine drained by catheterization.

Do Perceptions about Palliative Care Affect Emergency Decisions of Health Personnel for Patients with Advanced Dementia?

Decision analysis regarding emergency medical treatment in patients with advanced dementia has seldom been investigated. We aimed to examine the preferred medical treatment in emergency situations for patients with advanced dementia and its association with perceptions of palliative care. We conducted a survey of 159 physicians and 156 nurses from medical and surgical wards in two tertiary hospitals. The questionnaire included two case scenarios of patients with advanced dementia presenting gastrointestinal bleeding (scenario I) or pneumonia (scenario II) with a list of possible interventions and 11 items probing perceptions towards palliative care. Low burden interventions such as laboratory tests and intravenous administration of antibiotics/blood were preferred. Palliative measures such as analgesia/sedation were chosen by about half of the participants and invasive intervention by 41.6% (gastroscopy in scenario I) and 37.1% (intubation/mechanical ventilation in scenario II). Medical ward staff had a more palliative approach than surgical ward staff in scenario I, and senior staff had a more palliative approach than junior staff in scenario II. Most participants (90.4%) agreed that palliative care was appropriate for patients with advanced dementia. Stress in caring for patients with advanced dementia was reported by 24.5% of participants; 33.1% admitted fear of lawsuit, 33.8% were concerned about senior-level responses, and 69.7% were apprehensive of family members' reaction to palliative care. Perceptions of health care workers towards palliative care were associated with preferred treatment choice for patients with advanced dementia, mainly in scenario II. Attitudes and apprehensions regarding palliative care in these situations may explain the gap between positive attitudes towards palliative care and the chosen treatment approach. Acquainting emergency care practitioners with the benefits of palliative care may impact their decisions when treating this population.

Prognosis of Chronically Ventilated Patients in a Long-Term Ventilation Facility: Association with Age, Consciousness and Cognitive State.

Background: The number of adults requiring prolonged mechanical ventilation (PMV) including those with cognitive impairment or disorders of consciousness is escalating. We aimed to compare in a long-term acute care hospital (LTACH) mortality and length of stay (LOS) among three age groups (40-59y, 60-79y, ≥80y) of hospitalized PMV patients, and according to consciousness and cognitive state at admission. Methods: We obtained data from the health records of 308 adults aged ≥40 years requiring PMV hospitalized at a Chronic Ventilator Dependent Unit in a LTACH between 01/01/2015 to 06/30/2019 and followed-up until discharge or death or until 12/31/2019. Results: At admission to LTACH, 42.2% of PMV patients were in a vegetative state/ minimally conscious state (VS/MCS); 32.5% were severely cognitively impaired, 11.0% were mildly to moderately cognitively impaired, 12.3% had no cognitive impairment, and 1.9% had intellectual disability/psychiatric disorder. In-LTACH LOS (months) decreased from 34.6 ± 42.6 at age 40-59y, 19.1 ± 22.3 at 60-79y to 14.4 ± 19.3 at age ≥80y (p = .006). In-LTACH mortality was 30.6% for 40-59y, 41.1% for 60-79y and 54.8% for age ≥80y. In-LTACH LOS (months) was 23.8 ± 30.7 for VS/MCS, 15.1 ± 19.5 for the severely cognitively impaired, 10.0 ± 12.8 for mild to moderate cognitive impairment and 18.9 ± 21.9 for those without cognitive impairment (p = .02). In-LTACH mortality was 50.8% for VS/MCS, 58.0% for the severely cognitively impaired, 26.5% for mild to moderate cognitive impairment and 13.2% for those without cognitive impairment (p < .001). Conclusion: In this population requiring PMV, mortality and in-LTACH LOS worsened with age. In-LTACH LOS was longest for VS/MCS patients, who had a mean survival of about two years, followed by those without cognitive impairment and then those with severe cognitive impairment. Mortality was associated with worse consciousness and cognitive state. These findings highlight the importance of discussing end-of-life decisions with patients and family members regarding resuscitation/intubation and the long-term management of these patients.

Practice of end-of-life care for patients with advanced dementia by hospital physicians and nurses: Comparison between medical and surgical wards.

BACKGROUND: Patients with advanced dementia are commonly hospitalized in acute care wards, yet there is limited data regarding the end-of-life (EOL) care delivered to this population. The aim of the study was to examine EOL care delivered to patients with advanced dementia hospitalized on acute wards as reported by physicians and nurses. METHODS: Participants were physicians and nurses from medical and surgical wards of two tertiary hospitals in Israel. Participants completed a self-report questionnaire evaluating EOL care experiences, knowledge, performance, assessment, communication, and perceived futile care regarding patients with dementia. RESULTS: The questionnaire was completed by 315 providers. There were 190 medical ward respondents and 125 from general surgical wards. Of them, 48.6% recognized dementia as a terminal disease, while 26.0% of the participants reported that they knew the end-of-life preferences for less than 10% of their patients. Among the providers, 53.3% reported that end-of-life ward discussions took place only when there was a life-threatening situation and 11.1%-16.5% never engaged in end-of-life communication regarding EOL patient's preferences, appointing an attorney for the patient, disease trajectory or the essence of palliative care, with patients or their representatives. Only 17.1% reported "never" performing care they considered to be futile for patients with advanced dementia. Controlling for gender, age, role, position (senior/junior), and exposure to patients with advanced dementia, surgical ward respondents reported performing less EOL care than medical ward respondents in almost all aspects of palliative care. CONCLUSIONS: Despite growing attention, a significant portion of staff in acute care wards do not report applying EOL care to patients with advanced dementia in clinical practice, especially surgical ward staff.

Severe Protracted Hypophosphatemia in a Patient with Persistent Vegetative State on Long-Term Assisted Respiratory Support.

BACKGROUND Phosphorous is an essential component of cell structure and physiology, and is required for energy conservation and expenditure. Severe hypophosphatemia can lead to profound dysfunction and injury affecting most organs and can be life-threatening. It can also compromise weaning of mechanically ventilated patients. Long-term assisted ventilatory care in ambulatory or inpatient settings is an expanding medical service for patients with various forms of persistent or progressive incapacitating diseases. Hypophosphatemia, caused by respiratory alkalosis, has been reported in critical-care settings, but its occurrence in medically stable patients requiring long-term respiratory support has not been thoroughly investigated. CASE REPORT We report the case of a ventilated patient in a chronic vegetative state displaying progressive hypophosphatemia spanning over 3 months, with plasma levels gradually declining to 0.8 mg/dL. Evaluation did not reveal conditions leading to diminished phosphate absorption or enhanced urinary phosphate excretion, but it identified respiratory alkalosis related to a recent increase in target minute-volume ventilation in the adaptive support ventilation (ASV) mode as the cause of hypophosphatemia. Despite the very low plasma phosphate level, the patient was asymptomatic, probably because this type of hypophosphatemia may not represent physiologically significant intracellular phosphate depletion. The respiratory alkalosis resolved upon decreasing the target minute-volume ventilation settings, and serum phosphate was normalized. CONCLUSIONS Since blood gases are not routinely monitored in respiratory and hemodynamically stable patients on long-term respiratory support, hypophosphatemia may herald the development of significant respiratory alkalosis. Assessment of acid-base balance is thus warranted in patients receiving long-term ventilation, especially in those developing hypophosphatemia.

Practitioner Bias as an Explanation for Low Rates of Palliative Care Among Patients with Advanced Dementia.

Patients with advanced dementia are less likely than those with other terminal illnesses to receive palliative care. Due to the nature and course of dementia, there may be a failure to recognize the terminal stage of the disease. A possible and under-investigated explanation for this healthcare disparity is the healthcare practitioner who plays a primary role in end-of-life decision-making. Two potential areas that might impact provider decision-making are cognitive biases and moral considerations. In this analysis, we demonstrate how the cognitive biases and moral considerations of practitioners related to clinical decision-making are inherent in clinical practice and may impact on providers' accuracy related to diagnostic and treatment related decision-making associated with patients with advanced dementia. Anchoring, default, availability, representativeness and framing biases are cognitive biases based on the "Two System Model" that relate to decision-making in end-of-life care. In patients with advanced dementia, those biases may result in a tendency to adhere to traditional mandatory care, involving an aggressive approach to care, which values saving lives at all costs, without taking into account the possible suffering and long-term consequences. Aspects such as moral sensitivity and moral courage play an important role in ethical decision-making related to advanced dementia. Investigations of clinical decision-making that include the cognitive biases and ethical considerations of practitioners might advance the comprehensive understanding of the clinical decision-making process related to care of patients with advanced dementia and promote the quality of care given to this population.

Cardiac arrest in older adult patients.

PURPOSE OF REVIEW: To describe the epidemiology, prognostication, and treatment of out- and in-hospital cardiac arrest (OHCA and IHCA) in elderly patients. RECENT FINDINGS: Elderly patients undergoing cardiac arrest (CA) challenge the appropriateness of attempting cardiopulmonary resuscitation (CPR). Current literature suggests that factors traditionally associated with survival to hospital discharge and neurologically intact survival after CA cardiac arrest in general (e.g. presenting ryhthm, bystander CPR, targeted temperature management) may not be similarly favorable in elderly patients. Alternative factors meaningful for outcome in this special population include prearrest functional status, comorbidity load, the specific age subset within the elderly population, and CA location (i.e., nursing versus private home). Age should therefore not be a standalone criterion for withholding CPR. Attempts to perform CPR in an elderly patient should instead stem from a shared decision-making process. SUMMARY: An appropriate CPR attempt is an attempt resulting in neurologically intact survival. Appropriate CPR in elderly patients requires better risk classification. Future research should therefore focus on the associations of specific within-elderly age subgroups, comorbidities, and functional status with neurologically intact survival. Reporting must be standardized to enable such evaluation.

Age, pre-arrest neurological condition, and functional status as outcome predictors in out-of-hospital cardiac arrest: Secondary analysis of the Jerusalem Cohort Study data.

PURPOSE: Investigate the relation between age, baseline neurological and functional status, and survival after out-of-hospital cardiac arrest (OHCA). METHODS: Data analysis from the Jerusalem District Resuscitation Study. Patients >80 years and those 18-80 years with OHCA from 4/2005-12/2010 were compared. PRIMARY OUTCOME: survival at four time points; secondary outcomes: neurological and functional status at hospital discharge, and relationship between survival, age and pre-arrest activities of daily living (ADL) and Cerebral Performance Category (CPC) scores (higher scores indicate worse function in both). RESULTS: 3,211 patients (1,259 >80 years, 1952 aged 18-80) with median follow-up 5.9 years (range 0.1-11.1 years) were included. Survival was better for younger patients at all four time points, including 7.8% versus 2.5% at hospital discharge, 4.6% versus 0.2% at late follow-up. Functional status at discharge was also better, 4.8 ± 5.4 versus 9.0 ± 4.7, p<0.001, and more young patients had CPC1/2, 60.7% versus 32.2%, p = 0.004. Older patients who survived to emergency department admission had increased mortality per year of age (2.6%, hazard ratio [HR] 1.026, 95% confidence interval [CI] 1.006-1.048 versus 1.7%, HR 1.017, 95% CI 1.010-1.025), per point in pre-arrest ADL (3.0%, HR 1.030, 95% CI 1.007-1.054 versus 5.8%, HR 1.058, 95% CI 1.036-1.080), and per point in pre-arrest CPC (24%, HR 1.242, 95% CI 1.097-1.406 versus 37%, HR 1.370 95% CI 1.232-1.524). CONCLUSION: Patient independence before arrest may be a more crucial determinant of resuscitation outcome than older age alone. Discussion of end-of-life preferences is particularly important for older individuals with functional and cognitive decline.

Prolonged Mechanical Ventilation: A Comparison of Patients Treated at Home Compared With Hospital Long-Term Care.

OBJECTIVE: To compare the characteristics of patients treated with invasive prolonged mechanical ventilation (PMV) at home or in hospital long-term care (HLTC), specifically focusing on medical and functional status, caregiver strain, 6-month outcomes, and health maintenance organization (HMO) costs. DESIGN: Observational study. SETTING: A single HLTC and home hospital, serving a defined catchment area in the greater Jerusalem area, Israel. PARTICIPANTS: A total of 120 PMV patients aged ≥18 years, all insurees of the same HMO. All PMV patients in the local HMO were approached, of whom 46 of 47 home PMV and 74/76 HLTC patients were enrolled. MEASUREMENTS: Medical and sociodemographic factors, Barthel Index, Short Geriatric Depression Score, modified Caregiver Strain Index; 6-month follow-up for hospitalization, infections, pressure sores, and mortality; HMO costs. RESULTS: Home PMV was associated with younger age, improved functional status, financial difficulty, less comorbidity, and longer duration of PMV. Primary reasons for home PMV were degenerative neuromuscular disease and chronic lung disease, compared with acute illnesses with or without resuscitation among HLTC patients. Most home patients were alert and able to communicate (n = 40/46) versus HLTC (n = 22/74), and reported less depression. Caregiver strain was similar for home and HLTC. Among HLTC versus home patients, 6-month mortality (27% vs 7%, P = .012) and frequency of pressure sores (45% vs. 29%, P = .042) were higher in HLTC, with no differences for infection rates or hospitalization. In multivariate analyses, being treated at home with PMV was significantly associated with being able to communicate, lower age, financial difficulties, and improved functional status. HMO costs were one-third for home PMV versus HLTC. CONCLUSIONS AND IMPLICATIONS: Differing profiles were described for home and HLTC PMV patients, with lower rates of depression, pressure sores, mortality, and one-third the cost to HMO at home. Caregiver strain was similar irrespective of site of care. With appropriate targeting for eligible patients, home PMV is a viable and financially beneficial option.

Prolonged Mechanical Ventilation: Symptomatology, Well-Being, and Attitudes to Life.

OBJECTIVE: Although prolonged mechanical ventilation (PMV) is increasingly common, little is known concerning patient symptom burden or attitudes toward PMV. This study aims to describe the mood, well-being, distressing symptoms, and attitudes toward prolonged ventilation among PMV patients treated either at home or long-term acute care (LTAC). DESIGN: An observational study. SETTING AND PARTICIPANTS: 62 communicative participants treated with PMV, aged ≥18 years, insurees of a single HMO, treated at home hospital or LTAC specializing in ventilation in Jerusalem. MEASURES: Sociodemographic characteristics; chronic conditions; functional status; symptom burden measured by revised Edmonton Symptomatic Assessment System (r-ESAS); attitudes toward PVM. RESULTS: Participants were aged 61.7 ± 20.7 years, commonly suffered progressive neuromuscular disease (43.5%) or chronic lung disease (29%), were functionally dependent, treated at home (64.5%) or LTAC (35.5%), and had a mean PMV duration of 36.6 months (interquartile range 10.8-114.1). The 5-item, short Geriatric Depression Scale identified depression among 38% of participants, and was less at home vs LTAC (34% vs 44%, P < .001). Mean revised Edmonton Symptom Assessment System score was 24.5 ± 14.8 (maximum severity = 100), and participants reported severe or distressing symptoms for tiredness (27%/20%), pain (10%/25%), anxiety (16%/14%), depression (9%/21%), drowsiness (12%/17%), shortness of breath (9%/15%), poor appetite (7%/9%), and nausea (0%/10%). Impaired general well-being was reported as severe, moderate, mild, or none among 15%, 40%, 30%, and 15%, respectively. Only 1 patient had advance directives concerning ventilation prior to intubation, and when asked if they had to choose again today, 85% of patients would again opt for ventilation. CONCLUSIONS AND IMPLICATIONS: Few PMV patients reported distressing symptoms, and 85% would choose ventilation if asked again. These findings might be useful in clinical practice to assist in decision making concerning prolonged ventilation.

Rash induced by enteral vancomycin therapy in an older patient in a long-term care ventilator unit: case report and review of the literature.

BACKGROUND: Oral vancomycin is a first-line treatment for severe Clostridium difficile colitis. Oral vancomycin is perceived to lack systemic absorption or systemic adverse effects; however, a few cases of hypersensitivity to oral vancomycin have been reported, all in hospitalized patients. CASE PRESENTATION: In the present case, a 66-year-old woman with end-stage neurodegenerative disease residing in a long-term care facility developed a maculopapular rash following treatment with enteral vancomycin for recurrent C. difficile colitis. The rash resolved after withdrawal of the drug. CONCLUSION: Rashes associated with oral vancomycin treatment include maculopapular rash, urticaria, red man syndrome, and linear IgA bullous dermatitis. Risk factors for systemic vancomycin absorption include renal insufficiency, severe intestinal inflammation, and high vancomycin dose and duration. Routine serum testing of vancomycin levels, even in these high risk cases, is not recommended. Clinicians should be aware that enteral vancomycin can cause hypersensitivity reactions which may be serious.

The effect of body position on pulmonary function: a systematic review.

BACKGROUND: Pulmonary function tests (PFTs) are routinely performed in the upright position due to measurement devices and patient comfort. This systematic review investigated the influence of body position on lung function in healthy persons and specific patient groups. METHODS: A search to identify English-language papers published from 1/1998-12/2017 was conducted using MEDLINE and Google Scholar with key words: body position, lung function, lung mechanics, lung volume, position change, positioning, posture, pulmonary function testing, sitting, standing, supine, ventilation, and ventilatory change. Studies that were quasi-experimental, pre-post intervention; compared ≥2 positions, including sitting or standing; and assessed lung function in non-mechanically ventilated subjects aged ≥18 years were included. Primary outcome measures were forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC, FEV1/FVC), vital capacity (VC), functional residual capacity (FRC), maximal expiratory pressure (PEmax), maximal inspiratory pressure (PImax), peak expiratory flow (PEF), total lung capacity (TLC), residual volume (RV), and diffusing capacity of the lungs for carbon monoxide (DLCO). Standing, sitting, supine, and right- and left-side lying positions were studied. RESULTS: Forty-three studies met inclusion criteria. The study populations included healthy subjects (29 studies), lung disease (nine), heart disease (four), spinal cord injury (SCI, seven), neuromuscular diseases (three), and obesity (four). In most studies involving healthy subjects or patients with lung, heart, neuromuscular disease, or obesity, FEV1, FVC, FRC, PEmax, PImax, and/or PEF values were higher in more erect positions. For subjects with tetraplegic SCI, FVC and FEV1 were higher in supine vs. sitting. In healthy subjects, DLCO was higher in the supine vs. sitting, and in sitting vs. side-lying positions. In patients with chronic heart failure, the effect of position on DLCO varied. CONCLUSIONS: Body position influences the results of PFTs, but the optimal position and magnitude of the benefit varies between study populations. PFTs are routinely performed in the sitting position. We recommend the supine position should be considered in addition to sitting for PFTs in patients with SCI and neuromuscular disease. When treating patients with heart, lung, SCI, neuromuscular disease, or obesity, one should take into consideration that pulmonary physiology and function are influenced by body position.

Barriers to palliative care for advanced dementia: a scoping review.

People with dementia often fail to receive palliative care, despite increased recognition of their need and eligibility for such care. The aims of this study were to assess the barriers associated with a lack of implementation of palliative care for people with dementia and to explore whether there is a gap in knowledge necessitating further study. We reviewed the English literature published from 2000 to 2016, related to barriers to palliative care for people with dementia. Twenty-two articles met inclusion criteria for the review. Most originated in Europe or North America and were qualitative in nature. Four key themes were identified: administrative/policy issues, education, communication, and staff personal characteristics. Barriers to the delivery of palliative care for people with dementia have been studied for more than a decade, yet at present, there is a lack of consensus in practice. More research is needed related to barriers associated with personal characteristics. Such investigations have the potential to improve and better understand the complex nature of palliative care in this population.

Reduction of health care-associated infection indicators by copper oxide-impregnated textiles: Crossover, double-blind controlled study in chronic ventilator-dependent patients.

BACKGROUND: Copper oxide has potent wide-spectrum biocidal properties. The purpose of this study is to determine if replacing hospital textiles with copper oxide-impregnated textiles reduces the following health care-associated infection (HAI) indicators: antibiotic treatment initiation events (ATIEs), fever days, and antibiotic usage in hospitalized chronic ventilator-dependent patients. METHODS: A 7-month, crossover, double-blind controlled trial including all patients in 2 ventilator-dependent wards in a long-term care hospital. For 3 months (period 1), one ward received copper oxide-impregnated textiles and the other received untreated textiles. After a 1-month washout period of using regular textiles, for 3 months (period 2) the ward that received the treated textiles received the control textiles and vice versa. The personnel were blinded to which were treated or control textiles. There were no differences in infection control measures during the study. RESULTS: There were reductions of 29.3% (P = .002), 55.5% (P < .0001), 23.0% (P < .0001), and 27.5% (P < .0001) in the ATIEs, fever days (>37.6°C), days of antibiotic treatment, and antibiotic defined daily dose per 1,000 hospitalization days, respectively, when using the copper oxide-impregnated textiles. CONCLUSIONS: Use of copper oxide-impregnated biocidal textiles in a long-term care ward of ventilator-dependent patients was associated with a significant reduction of HAI indicators and antibiotic utilization. Using copper oxide-impregnated biocidal textiles may be an important measure aimed at reducing HAIs in long-term care medical settings.

Potentially Inappropriate Medications in Older Adults: Why the Revised Criteria Matter.

The 2 most widely used explicit criteria regarding inappropriate medication use in older adults are the American Geriatrics Society's Beers Criteria and the Screening Tool of Older People's Prescriptions/Screening Tool to Alert to Right Treatment (STOPP/START). Both documents were updated recently. They are important educational tools that highlight medications for which risks of use may often exceed benefits in older adults and situations in which potentially appropriate medications should be considered for use. The application of these tools has the potential to significantly affect patient care. Thus, it is important for clinicians to be familiar with both documents.

"What shall I do unto this people?" - BIOETHICAL DILEMMAS IN JEWISH THOUGHT ON MEDICAL RESOURCE ALLOCATION: THE COEXISTENCE OF OPPOSING VIEWS.

Life and death decisions have always been part of the medical profession. Modem discussions on resource allocation in health care deal with such critical situations, and seek ethical solutions that will benefit individuals and society as well as conserve scarce resources. Deontological ethics and utilitarianism are opposing ethical views, each with its own theory on solving moral dilemmas. Utilitarian logic aims at maximizing the benefit for the greatest number of people, while deontological theories strive to uphold pervasive moral principles. Jewish thought has always confronted the toughest of human predicaments head-on. As we review part of the Jewish discourse on distributive justice throughout the ages, we will show its relevance to modem discussions on medical resource allocation. As in modem secular ethics, Jewish thought juxtaposes the two aforementioned philosophical viewpoints, and constantly attempts to reconcile them. Extracting from each theory its strengths, the ethical conclusions reached in Jewish religious texts are relevant to issues of resource allocation throughout the ages.
