Stability of human urinary gonadotropin peptide

OBJECTIVE: To examine the effect of full implementation of advanced skills by ambulance personnel on the outcome from out of hospital cardiac arrest. SETTING: Patients with cardiac arrest treated at the accident and emergency department of the Royal Infirmary of Edinburgh. METHODS: All cardiorespiratory arrests occurring in the community were studied over a one year period. For patients arresting before the arrival of an ambulance crew, outcome of 92 patients treated by emergency medical technicians equipped with defibrillators was compared with that of 155 treated by paramedic crews. The proportions of patients whose arrest was witnessed by lay persons and those that had bystander cardiopulmonary resuscitation (CPR) were similar in both groups. RESULTS: There was no difference in the presenting rhythm between the two groups. Eight of the 92 patients (8.7%) treated by technicians survived to discharge compared with eight of 155 (5.2%) treated by paramedics (NS). Of those in ventricular fibrillation or pulseless ventricular tachycardia, eight of 43 (18.6%) in the technician group and seven of 80 (8.8%) in the paramedic group survived to hospital discharge (NS). For patients arresting in the presence of an ambulance crew, four of 13 patients treated by technicians compared with seven of 15 by paramedics survived to hospital discharge. Only two patients surviving to hospital discharge received drug treatment before the return of spontaneous circulation. CONCLUSIONS: No improvement in survival was demonstrated with more advanced prehospital care.     

Silicone breast implants and long-term health effects: when are data adequate?

STUDY OBJECTIVE: To determine whether ambulance transport time from the scene to the emergency department is faster with warning lights and siren than that without. DESIGN: In a convenience sample, transport times and routes of ambulances using lights and sirens were recorded by an observer. The time also was recorded by a paramedic who drove an ambulance without lights and siren over identical routes during simulated transports at the same time of day and on the same day of the week as the corresponding lights-and-siren transport. SETTING: An emergency medical service system in a city with a population of 46,000. PARTICIPANTS: Emergency medical technicians and paramedics. RESULTS: Fifty transport times with lights and siren averaged 43.5 seconds faster than the transport times without lights and siren [t = 4.21, P = .0001]. CONCLUSION: In this setting, the 43.5-second mean time savings does not warrant the use of lights and siren during ambulance transport, except in rare situations or clinical circumstances.     

An Analogue Study of Therapist Empathic Process: Working With Difference.

Most theories of psychotherapy advocate therapist empathy, although little is known about the process. A study, using analogue clinical scenarios, suggests psychotherapists can bridge perceived differences between their clients' life experiences and their own. Ninety three therapists viewed 5 videotaped vignettes based on actual cases. Each completed a demographic questionnaire, Interpersonal Reactivity Index (M. H. Davis, 1980), vignette response empathy scale, difference measure, reference point questionnaire, and self-perceived empathy measure. Findings show therapists perceived scenarios as different from their lives and that they were generally empathic across client vignettes. Gender differences emerged on measures of empathy. The research suggests therapists' ability to use reference points from their own experience may help facilitate empathy when responding to client life stories of difference.

Magnetic resonance imaging relaxation times and gadolinium-DTPA relaxivity values in human cerebrospinal fluid

The purpose of this qualitative phenomenological study was to explore the lived-experience of childhood cancer survivors with regard to their patterns of interaction with family and the environment using Newman's theory of Health as Expanding Consciousness, which proposes that experiencing a devastating event promotes an expanded consciousness. The sample consisted of five young adults, ages 23 to 26 years, who had experienced childhood cancer and now are considered to be cured of their initial cancer. A hermeneutic dialectic approach was used, with each subject being asked to respond to one open-ended question, "What are the most meaningful events in your life?" The interviews were analyzed for evidence of expanded consciousness, changing relatedness, and other universal themes. Individual patterns emerged and themes were identified that supported Newman's theory, such as optimism and hope, stronger bonds to family and friends, increased capacity for empathy, a desire to help others, and deeper feelings for the value of life. The intensely personal and professional relationship that develops between pediatric oncology nurses and their patients can only be strengthened by the knowledge that these patients generally grew up to be caring and empathetic individuals, perhaps as a result of the nurses' loving care for them. This research also provided support for Newman's theory as a sound paradigm for nursing practice.     

Age differences in three facets of empathy: Performance-based evidence.

This study investigated age differences in cognitive and affective facets of empathy: the ability to perceive another's emotions accurately, the capacity to share another's emotions, and the ability to behaviorally express sympathy in an empathic episode. Participants, 80 younger (Mage = 32 years) and 73 older (Mage = 59 years) adults, viewed eight film clips, each portraying a younger or an older adult thinking-aloud about an emotionally engaging topic that was relevant to either younger adults or older adults. In comparison to their younger counterparts, older adults generally reported and expressed greater sympathy while observing the target persons; and they were better able to share the emotions of the target persons who talked about a topic that was relevant to older adults. Age-related deficits in the cognitive ability to accurately perceive another's emotions were only evident when the target person talked about a topic of little relevance to older adults. In sum, the present performance-based evidence speaks for multidirectional age differences in empathy. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Economic regulation of ambulance services in California

OBJECTIVE: This study was intended to identify economic regulatory programs used by California counties (including ambulance franchising and rate setting), to inventory their foci and application, and to identify differences around the state. By studying the variety of programs used in one state, this study establishes a framework for evaluation of state and local regulatory programs elsewhere. METHODS: This study surveyed all California local EMS agencies (LEMSAs); these are California's equivalent of regional EMS organizations. The survey achieved a 100% response rate, and all data involve population parameters obviating the need for inferential statistics. RESULTS: Seventy-three percent of California counties use economic regulations. Large-population counties and those that operate their own LEMSAs are more likely to use economic regulations than are small counties and those that participate in multicounty EMS agencies. Despite a preference for competition in the authorizing statute, most franchises were granted without competition to existing providers. The majority of franchises in the state were granted to public services. Most ambulance rate setting occurs outside of a competitive process. CONCLUSIONS: Economic regulations that were intended to provide a structured marketplace are often being used to protect existing providers, particularly public services, from competition. The growing interest by fire departments in entering the market for emergency ambulance service, along with the existing bias toward them in granting of franchises, does not bode well for use of the competitive process. The growth of managed care may change or eliminate the need for economic regulations but, if they are to continue, more state oversight should be considered.     

The case of myoepithelioma of the parotid gland

STUDY OBJECTIVE: To determine whether the environment of a moving ambulance affects the ability of our-of-hospital care providers to auscultate breath sounds. METHODS: Out-of-hospital care providers assessed breath sounds with a previously described breath-sounds model in a quiet environment (control) and in a moving ambulance. The setting was a nonurban emergency medical services system and an interhospital transport agency based at a 600-plus-bed tertiary care center. The participants were physicians, transport nurses, and advanced life support EMS providers routinely involved in the emergency out-of-hospital treatment and transportation of the ill and injured. The accuracy with which participants identified the presence or absence of breath sounds in the two environments was compared with the use of the chi 2 test, with the alpha-value set at .05. RESULTS: The accuracy of breath-sounds assessment in the control environment was 96% (251 of 260); the sensitivity was 96% and the specificity 97%. The accuracy of breath-sounds assessment in the experimental environment was 54% (140 of 260); the sensitivity was .09% and the specificity 98%. Participants were significantly less likely to hear breath sounds in the moving ambulance than in the quiet room (P < .001). CONCLUSION: Assessment of breath sounds is hampered by the environment of a moving ambulance.     

Endoscopic CO2 laser excision of large or recurrent laryngeal saccular cysts in adults

BACKGROUND: Most paediatric cardiac arrest studies have been conducted in the USA, where paramedics provide prehospital emergency care. We wanted to study the outcome of paediatric cardiac arrest patients in an emergency medical system which is based on physician staffed emergency care units. METHODS: We analysed retrospectively the files of 100 prehospital cardiac arrest patients from Southern Finland during a 10-year study period. The patients were less than 16 years of age. RESULTS: Fifty patients were declared dead on the scene (DOS) without attempted resuscitation, and cardiopulmonary resuscitation (CPR) was initiated in 50 patients. The sudden infant death syndrome was the most common cause of arrest in the DOS patients (68%) as well as in those receiving CPR (36%). Asystole was the initial cardiac rhythm in 70% of the patients in whom CPR was attempted. Resuscitation was successful in 13 patients, 8 of whom were ultimately discharged. Six of the patients survived with mild or no disability and 4 of them had near-drowning aetiology. In multivariate analysis, the short duration of CPR (< or = 15 min) was the only factor significantly associated with better survival. CONCLUSIONS: Although prehospital care was provided by physicians, the overall rate of survival was found to be equally poor as reported from systems with paramedics. The only major difference between physician- and paramedic-staffed emergency care units is the ability of physicians to refrain from resuscitation already on the scene when prognosis is poor.     

Directions for clinical research and genomic research into the next decade: implications for informatics

Managed care continues to revolutionize the provision of mental health services in the United States. Long-term, open-ended therapies have been replaced by short-term, highly focused interventions. Increasingly, managed care organizations rely on standardized preferred practice guidelines to give direction and focus to social work and other therapeutic interventions. Critics argue that changes effected by managed care, particularly the use of treatment guidelines, depersonalize the client-worker relationship and significantly reduce the role of empathy in the therapeutic process. Moreover, these critics suggest that overall client satisfaction with mental health services has deteriorated. This article presents a study that examined clients' perceptions of empathy and overall satisfaction with managed behavioral health care when the clients were in unstructured individual therapy or in time-limited standardized group therapy. The results reveal no significant difference in the clients' perception of empathy or of their overall satisfaction regardless of the type of treatment they received. This article describes the rationale and design of the study, presents the results, and discusses the implications for social work practice.     

Public trust and initiatives for new health care partnerships

Effective communication between doctor and patient is a critical component of high-quality care. The physician's credibility has a significant effect on treatment outcomes. Because changes in medicine and larger cultural trends challenge the ability of clinicians to engage their patients' trust, new kinds of partnerships must be created. To do this effectively, physicians have to sharpen their communication skills and devise strategies for assuring that their patients become informed allies in their own treatment. A number of innovations are helping to build these alliances: training in communication skills; creative uses of the Internet and videotape technologies; improved "customer service" programs; critical pathways for patients; and special educational aids. All these tools promise to be useful, but they require careful development and evaluation.     

Participatory action research as a strategy for empowering aboriginal health workers

A participatory action research project was undertaken with Aboriginal health workers on the Anangu Pitjantjatjara Lands in South Australia. The study examined the factors that affect the empowerment of Aboriginal health workers within the context of an Aboriginal-controlled primary health care service. This project was different from previous research conducted with Aboriginal health workers in remote areas for two reasons. First, it enabled them to participate actively as co-researchers in the study, and second, it brought about action and change during the research process. The three main factors preventing Aboriginal health workers from attaining a key role within the health service are the standard of training they receive, their low literacy and numeracy levels, and their lack of participation in decision making within the health service. Each of these factors is interrelated and all affect the Aboriginal health workers' ability to have more control and responsibility within the health service.     

Severe head trauma. Review of the factors influencing the prognosis

A series of 72 severely head injured patients are reported, 24 (33%) with surgical intracranial hematomas. All patients were intensively cared for under the same therapeutic regime; intracranial pressure (ICP) was monitored and treated if increased. The series mortality was 39%. Uncontrollable increase of ICP (UI-ICP), always fatal, was observed in 18% of patients and in 13 of 28 deaths (46%); the incidence of UI-ICP among deaths was higher in patients less than in those more than 40 years old (55% vs 25%). Patients with UI-ICP were frequently deeply comatose and with arterial hypotension on admission; almost all died in the first days. Patients directly admitted from the scene with well staffed Life Flight Helicopter Emergency Care compared with those directly admitted from the scene with different type of ambulance service (paramedics, police, firemen and private) had a mortality rate significantly less (20% vs 54%) and an incidence of UI-ICP strongly lower both among patients (5% vs 29%) and among deaths (25% vs 54%). Thus in this small series intensive care after admission was not effective to obtain good results if patients had received poor preadmission emergency care. Review of the literature on main clinical predictors of outcome in severe head injury, have made possible some observations. Ischemic and intracranial hypertension brain lesions were generally present in patients killed by head trauma; while diffuse axonal injury, frequently responsible for vegetative, severe disability survival and late deaths, was observed only in 20-30% of postmortem examinations. Old age, poor neurological status and cardiocirculatory and respiratory disturbances prior to and upon admission positively worsened the outcome, while intracranial hematomas had a more variable predictive value. Intracranial hypertension was a definitively ominous predictor only if very high when the risk to be or become uncontrollable seems to be much elevated. UI-ICP, often fatal despite any aggressive therapy, was the single most frequent killer after severe head injury, responsible for about half of all deaths after admission. The different outcome among severe head injury series could be conceivably related to a different frequency of UI-ICP. Besides the severity of head injury and delay and mode of admission, we suggest that preadmission respiratory and cardiocirculatory and the quality of emergency medical system could strongly affect the incidence of uncontrollable increase of ICP in admitted patients and thus the mortality rate and favorable recovery of the series. The advanced preadmission emergency care service with intensive care after admission could significantly explain the better results often observed in severe head injury series.     

Direct admission to the coronary care unit by the ambulance service for patients with suspected myocardial infarction

BACKGROUND: Direct access to the coronary care unit (CCU) for general practitioner (GP) referred cases of suspected acute myocardial infarction (AMI) (fast track admission) substantially reduces the time to thrombolysis. Until now, this policy has been confined to GP referrals. OBJECTIVES: To determine the time taken to admission to CCU under the fast track policy (ambulance referrals and GP referrals) and the time taken to start administration of thrombolytics (ambulance referrals, GP referrals, and accident and emergency referrals). METHODS: Fast track admission policy was extended to include referrals from ambulance personnel who respond to emergency service calls. Ambulance personnel referred cases were also examined to see if they were referred appropriately to the CCU. RESULTS: 100 ambulance personnel referrals and 260 GP referrals to CCU with chest pain were studied. Forty accident and emergency referrals who had AMI requiring thrombolysis were also studied. In the ambulance referred group the time to admission from phone call was a median of 10 minutes (range 2 to 45), a saving of 30 minutes compared with GP referrals (median 40 minutes, range 2 to 217). The median diagnostic electrocardiogram (ECG) to thrombolysis time was longer in the accident and emergency referrals with AMI than either ambulance referrals or GP referrals admitted under the fast track policy. Diagnostic ECG to thrombolysis time: accident and emergency 50 minutes (range 15 to 385); ambulance referrals median 33 minutes (range 6 to 69); GP referrals median 29.5 minutes (range 5 to 110 minutes); (p = 0.056 accident and emergency compared with ambulance referrals, p < 0.002 accident and emergency compared with GP referrals). Of 100 ambulance referrals 52 patients exhibited symptoms suggestive of ischaemic heart disease (confirmed AMI, unstable angina, and angina) and a further 18 patients were required to stay in CCU for other cardiac problems. Thus a total of 70 (70%) were considered appropriate compared with 155 of 260 (55.8%) GP referred cases. CONCLUSIONS: Extending the fast track admission policy to ambulance personnel reduces delay to admission for patients with suspected MI without adversely affecting the appropriateness of admissions.     

The influence of response patterns on the "refined empathy score."

"The refined empathy score, although controlling for similarity, is still an unsatisfactory measure of empathic ability. The patterns of response, previously unperceived, act through the scoring system to influence to a large extent, the refined empathy score. A subject receives a high empathy score, not necessarily because of his high empathic ability, but because of his pattern of response and the pattern of response of the associate whom he chooses."

"Ambulatory blood pressure and heart rate in healthy male paramedics during a workday and a nonworkday": Erratum.

Reports an error in "Ambulatory blood pressure and heart rate in healthy male paramedics during a workday and a nonworkday" by Iris B. Goldstein, Larry D. Jamner and David Shapiro (Health Psychology, 1992, Vol 11[1], 48-54). On page 52, the sentence "For example, the paramedics stood 16.44 times more while home than while at the station" should read "For example, the paramedics stood more while home than while at the station." (The following abstract of the original article appeared in record 1992-29445-001.) Compared ambulatory blood pressure (BP) and heart rate (HR) in 30 White male paramedics (aged 20-43 yrs) during a 24-hr workday and a 24-hr nonworkday. During the 24-hr period as a whole, there were no BP differences between the workday and the nonworkday, but HR was higher during the nonworkday than during the workday. Systolic BP (SBP) recorded in the ambulance on the workday was elevated 9.8 mm Hg, compared with SBP recorded in a car on the nonworkday; it was also 7.2 mm Hg higher at the scene of an accident and at the hospital than during nonworkday activities. Ratings of moods in diaries indicated that paramedics felt more unhappiness, stress, and sadness and less feelings of pleasantness at work than at home. Rather than being elevated for the entire 24-hr period, work BP seemed to reflect the relatively high stress associated with specific situations in the work of a paramedic.

Emergency ambulance assistance in The Netherlands: is the Dutch situation optimal?

The system of prehospital trauma care in the Netherlands is the subject of great concern. Although many improvements have been achieved in the last decade, there are still some deficits. Legislation concerning the minimal level of education for ambulance attendants was recently upgraded to 'registered nurse', a standard which must be achieved by 1997. Standardization with regard to extrication techniques, equipment and methods of treatment in prehospital trauma care does not yet exist. Although aware of the fact that large regional differences exist throughout the USA, a system of care in accordance with the advanced trauma life support (ATLS) standard of the American College of Surgeons (ACS) and by means of prehospital and advanced trauma life support (PHTLS) given according to the standards of the National Association of Emergency Medical Technicians (NAEMS) was considered to be the 'golden standard'. Nineteen ground ambulance and two helicopter services in different states of the USA, working according to ACS/NAEMS standard, were visited to analyse the system of care, with special reference to (para)medical education, communication, logistics, and immobilization materials and techniques. In the Netherlands all 41 central post ambulance services (CPAs) were asked to return a questionnaire. This resulted in a 90% (37 out of 41) response. The deficits of the Dutch system of care related to the PHTLS/ATLS standard are pointed out, resulting in recommendations to improve the Dutch system. The requirements of the dispatcher are far inferior to the optimal situation, which, together with the lack of technical equipment, results in serious communication problems. The Dutch ambulance attendant education, in which in the present system the education level reaches 'registered nurse' in only 91% and specialized courses are not mandatory, should be upgraded to the PHTLS level of care.     

Ambulatory blood pressure and heart rate in healthy male paramedics during a workday and a nonworkday.

Calling all patients

Hospitals must establish patients' expectations of care and their satisfaction with the care delivered. This telephone survey tool measures patient satisfaction based on empathy, communication, competence and continuity of care, and amenities.     

Prion diseases

Empathy plays a central role in social relationships, and lack of empathy has been suggested as part of expressed emotion in the relatives of patients with schizophrenia. The aim of this research is to measure empathy in the relatives of schizophrenia patients and to establish the relationship between lack of empathy and relapse. Eighty schizophrenia patients were followed up in a 2-year prospective cohort study. Relatives' empathy, defined as the ability to perceive the patient's mood state, was measured at the beginning of the study with a questionnaire given after a 10-minute interaction between the patient and his or her relative. Several other attitudinal, clinical, and social variables were also measured. A significant relationship was found between poor empathic attitude and relapse. Lack of treatment compliance, negative symptoms, unemployment, and poor premorbid adjustment were also associated with relapse. In a multivariate analysis, the association between poor empathic attitude and relapse was maintained. Statistical control of the relatives' critical attitude showed that each kind of attitude predicts relapse independently.     

A method to reduce response times in prehospital care: the motorcycle experience

This study compared the response times of a motorcycle and a standard ambulance in a congested urban emergency medical services (EMS) setting. The study was performed in Taipei, Taiwan, a densely populated urban area. A basic life support (BLS) motorcycle (without defibrillation capability) and an advanced life support (ALS) ambulance were based at three study hospitals and simultaneously dispatched when there was a perceived need for ALS ambulance transport. Over a 3-month period, prehospital personnel evaluated 307 medical and trauma emergencies. Time data were insufficient for analysis in 33 cases, leaving a study population of 274. Response times of the motorcycle and the ambulance were prospectively assessed and compared. During rush hours, the response times of the motorcycle and ambulance were 4.9+/-3.0 minutes and 6.3+/-3.4 minutes (P < .05), respectively, and in non-rush hours, 4.2+/-2.1 minutes and 5.1+/-2.5 minutes (P < .05), respectively. Using motorcycles to transport EMTs to the emergency scene significantly reduced response time compared with a standard ambulance in a congested urban setting. Large prospective studies are required to determine the impact on patient outcome of shorter EMS response times using motorcycles. EMS motorcycles appear feasible and deserve consideration to help expedite prehospital care in other systems in densely populated cities.
