Identification and definition of long-stay mental hospital population.

In a study to identify and define a central group of long-stay psychiatric patients who are resistant to discharge 422 were found who had been in hospital for eight to 23 years. These "problem" patients represented 40% of all long-stay patients. The total number of years that they had spent in hospital was nearly double that of the remaining patients. They were mostly unvisited, unoccupied, and single, and most were suffering from schizophrenia or organic psychosis. Half were in a good or reasonably good state of mental health, and three-quarters were in a good or reasonably good state of physical health. The findings have implications for the rehabilitation and treatment of these patients and also for the provision of community aftercare facilities.     

Attendance of general practitioners at child protection case conferences.

OBJECTIVE--To investigate general practitioners'' attendance at and views on child protection conferences and their confidence in dealing with sexual abuse in children. DESIGN--Anonymous postal questionnaire sent to all general practitioners in Tower Hamlets and review of consecutive case conferences held by social services for three months in 1989. SETTING--Tower Hamlets health district. SUBJECTS--91 general practitioners, 56 of whom (62%) responded. MAIN OUTCOME MEASURES--Number of conferences attended, reasons for non-attendance, and reported confidence in dealing with sexual abuse. RESULTS--General practitioners estimated that 202 child protection conferences had been held in 1989 on their patients and that they had attended 85 of these. Information from social services for three months suggested that general practitioners had attended only nine of the 114 conferences reviewed. Timing of the conference was the most important reason for non-attendance. All respondents wanted access to the minutes of these conferences irrespective of their own attendance. Most general practitioners were very or moderately confident of their ability to detect child sexual abuse and non-accidental injury and to communicate with the family. CONCLUSION--More effort should be made to ensure that general practitioners are notified of case conferences and that the timing and location of conferences is compatible with their other commitments.     

Specific and gender differences between hospitalized and out of hospital mortality due to myocardial infarction

In this paper, the authors evaluate gender related differences of myocardial infarction mortality before and after hospital admittance. Myocardial infarction mortality in the Clinical Hospital Split in the seven years period between 2000 and 2006, have been analyzed together with out of hospital sudden death patients with acute myocardial infarction established during autopsy. During the seven year period between 2000 and 2006, 3434 patients were treated for myocardial infarction in the Split Clinical Hospital, 2336 (68%) males and 1098 (32%) females with a 12% total mortality (427 patients). The annual number of hospitalized persons has been increasing during that period (474 in yr. 2000 us. 547 in yr. 2006), while mortality decreased from 15% in 2000 to 9.6% in 2006. Female patients had significantly higher hospital mortality than male patients, (228 or 21% vs. 202 or 9%, p<0.05). Women also had significantly higher total AMI mortality (23.7% vs. 15,7%, p <0.05). Anterior myocardial infarction with ST elevation in precordial leads had significantly higher mortality (19%) compared to patients with lateral (11%), inferior (10%) myocardial infarction with ST elevation and also NSTEMI (4%) mortality p<0.05. Female patients more frequently die in hospital, 84% (230) than out of hospital 16% (43). From the total number of AMI deaths (388) in male patients, 56% (217) were in hospital and 44% (171) out of hospital (p<0.001). Men had significantly higher prehospital mortality rate than women (81% vs. 19%, p<0.05). Men also more frequently died from ventricular fibrillation (22% vs. 10%, p<0.05), while women died more frequently of heart failure, cardiogenic shock, and myocardial rupture (33% vs. 15% p<0.05). Regarding the total number of deaths from myocardial infarction men had significantly higher prehospital mortality compared to women (178 or 7.3% vs. 43 or 3.7%, p<0.05). Anterior myocardial infarction had a significantly higher rate in patients dying pre-hospital (58%), in contrast to inferior (36%) and lateral myocardial infarction with ST elevation (6%) p<0.05. We have concluded that male patients die more frequently within the first few hours of AMI mostly due to malignant arrhythmias, while female patients died in sub acute stage due to heart failure while being hospitalized. Nevertheless total mortality of AMI remains significantly higher in women.     

Reduction in hospital readmission stay of elderly patients by a community based hospital discharge scheme: a randomised controlled trial.

STUDY OBJECTIVE--To compare a community support scheme using care attendants with standard aftercare for their effects on independence and morale of elderly patients discharged from hospital and on their use of health and social services. DESIGN--Randomised controlled study of cohort of patients over 75 discharged to their own homes. SETTING--District general hospital and community. PATIENTS--Total of 903 patients (mean age 82, 25% over 85). INTERVENTIONS--Total of 464 patients received support from care attendants on first day at home and for up to 12 hours a week for two weeks. Support comprised practical care, help with rehabilitation, and organising social help. The remaining 439 patients received standard aftercare. END POINT--Difference between two groups of 7% in hospital readmission rates or one point on activities of daily living scale (power 80%, significance level 5%). MEASUREMENTS AND MAIN RESULTS--Three months after the initial discharge 763 patients were interviewed (84%). There were no significant differences between the two groups in physical independence (activities of daily living scale), in measures of morale (Philadelphia scale), or in death rates. Hospital readmission rates within 18 months of discharge, however, were significantly higher in the control group and they spent more days in hospital (mean; control group 30.6 days, support group 17.1 days; p = 0.014). Of the patients living alone who were followed up for 18 months 21 (15%) receiving standard aftercare were readmitted more than twice compared with 6 (5%) supported by care attendants (p less than 0.01). CONCLUSIONS--If the findings are confirmed, and the policy extended to all patients over the age of 75 living alone, an average health district might expect either to save about 23 hospital beds at a net annual saving of about pounds 220,000 in the short term or to increase available beds by this number.     

Evidence that treatment with vaccinia melanoma cell lysates (VMCL) may improve survival of patients with stage II melanoma

Summary A total of 80 patients with melanoma metastases in regional lymph nodes were treated by i.d. injections with a vaccine prepared from a vaccinia virus-infected allogeneic melanoma cell line; 39 patients have been followed for a 2-year period. Interim results from comparison of the treated group with 151 historical controls treated without the vaccine from September 1978 to December 1981 at the same institution and 56 non-randomized concurrent controls suggest that survival was significantly prolonged in the vaccinated group. At the 2-year period overall survival was 75% in the treated compared to 57% in the historical control group. Subset analysis showed a greater apparent benefit of vaccine therapy among patients who had metastases detected at the time of treatment of the primary melanoma (synchronous metastases), while therapy appeared less effective in patients with metastases detected at some time after treatment of the primary (delayed metastases). In the latter only those with one lymph node appeared to benefit from the treatment whereas in patients with synchronous metastases patients with three or more nodes as well as one node appeared to have improved survival. The survival rates at 2 years for treated patients with synchronous metastases in one, two, three or more lymph nodes was 100%, 83% and 79% respectively compared with that of 82%, 86% and 47% respectively in the equivalent control groups. Survival rates in treated patients with delayed metastases in one, two, three or more lymph nodes was 70%, 70% and 65% compared with 47%, 42% and 35% in the equivalent control groups. Treatment and control groups appeared well matched for a number of known prognostic features, including number and size of involved nodes, sex and thickness of primary tumor. Multivariate analysis indicated the effect of treatment was independent of these factors. Despite the empiricism of this approach the present results suggest that this form of therapy warrants further evaluation in a randomized controlled trial.     

Oesophageal cancer treatment in North East Thames region, 1981: medical audit using Hospital Activity Analysis data.

Figures from the Hospital Activity Analysis in the North East Thames region in 1981 were used to perform a medical audit on oesophageal cancer treatment. Four hundred and forty four patients were admitted with this diagnosis; 80 had been intubated without a thoracotomy or laparotomy, and 73 had had surgery (two thirds radical and one third palliative) with an overall operative mortality of 33%. Fifty five patients had had radiotherapy and 179 patients had no recorded operation or investigation. One hundred and seventy seven different consultants had looked after all these inpatients, most being general surgeons. Only five consultants had looked after 10 or more patients each year. From a calculated estimate of a total 286 patients in the region, 28% had palliative intubation and 25% had surgery; 20% of all the patients had radiotherapy either as a radical or palliative treatment, the remainder having no recorded therapeutic procedure. One hundred and eighty seven patients (66% of the calculated total) died in hospital. Investigation and treatment do not seem to be limited by lack of money, but money is being wasted by admitting patients for terminal care into acute hospital beds. It would be more humane for these patients to die at home or in a hospice if they wished.     

Monitoring the presence of genetically modified food on the market of the Republic of Croatia

From the beginning of the human race people have been applying different methods to change the genetic material of either plants or animals in order to increase their yield as well as to improve the quality and quantity of food. Genetically modified organism (GMO) means an organism in which the genetic material has been altered in a way that does not occur naturally by mating and/or natural recombination. Analysing the presence of GMO in food is done by detecting the presence of either specific DNA sequences inserted in the genome of transgenic organism, or detecting proteins as a result of the expression of the inserted DNA. In this work food testing for the presence of genetically modified organisms was conducted during the period from 2004 to 2007 in the GMO laboratory of the Croatian National Institute of Public Health. According to the regulations, among the samples in which the presence of GMO was detected, all those which had more than 0.9% of GMO content were either rejected from the border or removed from the market, because such GM food has to be appropriately labelled. Among the food samples which were analysed in 2004: 127 (2.37%) of a total of 1226 samples contained more than 0.9% of GMOs; in 2005 there was only one in 512 (0.20%) samples in total; in 2006 there were 4 out of 404 samples (0.99%), and in 2007: 7 of a total of 655 samples (1.07%) had GMO content above the allowed threshold of 0.9%.     

Fine needle aspiration biopsy versus sputum and bronchial material in the diagnosis of lung cancer. A comparative study of 168 patients

A group of 168 consecutive lung cancer patients in whom a definitive diagnosis of primary lung cancer was established either in a conventional cytologic specimen of sputum or bronchial material or in a specimen obtained by fine needle aspiration (FNA) biopsy was reviewed to compare the relative accuracies between the modalities of sputum and bronchial material on one hand versus FNA cytology on the other in the diagnosis of lung cancer. The patients included in the study were selected from a total of 1,093 patients who had been diagnosed and treated for lung cancer at Duke University Medical Center over the five-year period of January 1, 1980, through December 31, 1984. In 325 (29.8%) of the 1,093 patients, a definitive cancer diagnosis was established from histopathologic study alone, without any cytologic diagnoses. In 420 patients (38.4%), both histologic and cytologic material had been interpreted as being conclusively diagnostic for lung cancer. In 348 patients (31.8%), a cytologic diagnosis of lung cancer was made without a histologic confirmation. Thus, in a total of 768 (70.3%) of the 1,093 cases, a definitive cytologic diagnosis of cancer had been made. Of these 768 patients, 168 had been evaluated by both conventional respiratory cytologic methods (examination of sputum and bronchial material) and with FNA biopsy cytology. In 9 patients (5.4%), only conventional respiratory cytologic specimens were conclusively diagnostic for cancer. In 122 patients (72.6%), only the FNA biopsy specimen was diagnostic. In 37 patients (22.0%), both conventional respiratory specimens and FNA specimens yielded a definitive lung cancer diagnosis. The FNA specimen was the only positive cytologic specimen in 90.2% of large cell undifferentiated carcinomas, 79.5% of adenocarcinomas, 66.7% of small cell undifferentiated carcinomas and 58.2% of squamous cell carcinomas. In 26.5% of the patients, a diagnosis of cancer could have been established on conventional cytologic specimens, without the necessity of proceeding to percutaneous FNA biopsy. From this study, it is concluded that the techniques of conventional respiratory cytology and FNA biopsy cytology are complementary in the diagnosis of lung cancer. While the percentage of lung cancers diagnosed by FNA biopsy cytology alone is much greater than that obtained by conventional respiratory cytology alone, more than one-fourth of these cancers could be detected by the less invasive techniques of sputum collection and bronchoscopy.     

Incidence of oropharyngeal candidosis in stem cell transplant (SCT) patients

Eighty persons with haematological malignancies receiving stem cell transplantation (SCT) were examined over a 24 months period. Hyposalivation, a common complaint in patients treated by intensive chemotherapy and radiotherapy can predispose to oral candidal colonisation as well. This study was focused on correlation between the fungal colonisation of the oral cavity and the total unstimulated saliva flow rate of 80 patients with haematological malignancies before and after stem cell transplantation and in addition, on their oral health state. Despite the fact that prior to being involved in the transplantation programme, the patients were subjected to dental examination and decayed teeth were found in 20 out of 80 patients (25%). From the 2233 different oropharyngeal specimens fungi were isolated before conditioning from 16 patients (20%), and during aplasia from 19 patients (23.7%). Objective xerostomia (unstimulated total saliva flow rate < or = 0.1 ml/min) was detected in 28 patients (35%). Stem cell transplant patients with pretransplant mouth dryness had higher incidence of Candida albicans and other fungal colonisation than those with normal saliva secretion.     

Surgical management of chronic occlusive disease of the aortic arch vessels and vertebral arteries.

Occlusive disease of the aortic arch vessels is relatively rare and often missed initially. Of 41 patients treated surgically for this condition over a 10-year period 38 had arteriosclerotic lesions, 2 had symptoms secondary to vasculitis (Takayasu''s arteritis) and 1 had a radiation injury to a subclavian artery. In 22 cases the left subclavian artery was involved; the right subclavian and innominate arteries were the next most commonly affected. Only four vertebral stenoses were treated. Most patients presented with a combination of arm and hindbrain ischemia that was shown radiologically to be associated with a subclavian steal syndrome, but in some only isolated arm symptoms or severe vertigo alone was experienced. There was a difference in blood pressure between the arms of at least 20 mm Hg in 88% of the patients. The treatment for 28 patients was creation of a carotid-subclavian bypass, for 6 the placement of a bypass graft from the ascending aorta to the subclavian or carotid artery or both, for a 3 a subclavian endarterectomy and for 4 vertebral angioplasty. There were no operative deaths, and 90% of the grafts were patent 1 to 72 months later. however, only 30 (73%) of the patients were asymptomatic and 9 (22%) had improved.     

Breaking out of the echo chamber: missed opportunities for genetics at conservation conferences

Genetic approaches have proven useful for addressing various conservation problems, but genetics remains poorly integrated into conservation practice. Multidisciplinary conservation conferences present excellent opportunities for bridging the conservation-genetics gap and facilitating cross-disciplinary projects. We hypothesize that there is a tendency for presentations featuring genetic approaches to be siloed into approach specific sessions, creating an “echo chamber”; geneticists are left talking amongst themselves, hindering collaboration across disciplines. To test this, we reviewed abstracts from the past six Society for Conservation Biology conferences and assessed how presentations featuring genetics/genomics were distributed throughout the respective programs. We found that: the segregation of presentations featuring genetics varied widely between conferences (22–78 %); that no other method or approach was segregated to the same degree; and that the vast majority (99 %) of presentations featuring genetics had broader applications that made them appropriate for other sessions. We argue that segregating genetics at conservation conferences in this way is unhelpful and serves to strengthen the idea that genetics is not relevant to a wider conservation audience. We recommend that; (1) conference organisers endeavour to facilitate the integration of genetics into sessions based on the conservation questions addressed, rather than the methods used to address them; and (2) geneticists make the practical application of their work clear at abstract submission and during presentations. These recommendations are not novel, but our data illustrate a clear need for them to be implemented to better facilitate integration of genetic research that will benefit conservation outcomes.     

Congenital Cataract: Prevalence and Surgery Age at Zhongshan Ophthalmic Center (ZOC)

Congenital cataract (CC) is the primary cause of treatable childhood blindness. Population-based assessments of prevalence and surgery age of CC, which are critical for improving management strategies, have been unavailable in China until now. We conducted a hospital-based, cross-sectional study of the hospital charts of CC patients younger than 18 years old from January 2005 to December 2010 at Zhongshan Ophthalmic Center (ZOC) in Guangzhou, China. Residence, gender, age at surgery, hospitalization time, and the presence of other ocular abnormalities were extracted and statistically analyzed in different subgroups. The search identified 1314 patients diagnosed with CC from a total of 136154 hospitalizations, which accounted for 2.39% of all the cataract in-patients and 1.06% of the total in-patients over the six-year study period. Of the identified CC patients, 9.2% had ≥2 hospitalizations due to the necessity of additional surgeries, with a total ratio of boys to girls of 1.75∶1. Based on a subgroup analysis according to age, patients 2–6 years old constituted the highest proportion (29.22%) of all hospitalized CC patients, and those 13–18 years old constituted the lowest proportion (13.47%) of the total number. The average age at surgery was 27.62±23.36 months, but CC patients ≤6 years old (especially ≤6 months old) became increasingly prevalent throughout the 6-year study period. A total of 276 cases (20.93%) of CC were associated with one or more other ocular abnormalities, the highest incidence rates were observed for exotropia (6.24%), nystagmus (6.16%), and refractive error (3.65%). In conclusion, CC patients accounted for 2.39% of all cataract in-patients in a review of 6 years of hospitalization charts from ZOC. The age at the time of surgery decreased over the 6-year study period, which probably reflects the continuing improvement of public awareness of children’s eye care in China.     

Complications of tonsillectomy and adenoidectomy in 9409 children observed overnight.

In attempts to minimize the cost of health care, physicians are reducing the duration of hospital stay. Traditionally, at the Hospital for Sick Children, Toronto, otherwise healthy children undergoing adenoidectomy, tonsillectomy or adenotonsillectomy have been admitted the morning of surgery and discharged from hospital at 7 am the next day. The nursing records of 9409 patients aged 17 years or less who were managed in this way between 1980 and 1984 were reviewed to determine the occurrence of complications during the observation period. A total of 202 patients (2.15%) bled during the observation period. Of the 202, 6 (0.06% of all the patients) required a second general anesthetic for hemostasis; 1 of these 6 patients and 5 others required blood transfusions. Discharge was delayed for 42 patients (0.45% of all the patients) because of postoperative bleeding and for 57 patients (0.6%) for a variety of other reasons. Delayed discharge for reasons other than hemorrhage was more frequent among children less than 2 years of age and those over 12 years of age. The authors concluded that children undergoing adenoidectomy could safely be discharged the same day after 6 hours of observation following surgery. However, as a substantial number of children bled from the tonsillar fossa more than 6 hours after surgery, the efficacy of periodic examination of the oral cavity during the observation period in reducing the rate of hemorrhage after 6 hours must be evaluated before a same-day discharge program is established for children undergoing adenotonsillectomy.     

Peer-Selected “Best Papers”—Are They Really That “Good”?

Background

Peer evaluation is the cornerstone of science evaluation. In this paper, we analyze whether or not a form of peer evaluation, the pre-publication selection of the best papers in Computer Science (CS) conferences, is better than random, when considering future citations received by the papers.

Methods

Considering 12 conferences (for several years), we collected the citation counts from Scopus for both the best papers and the non-best papers. For a different set of 17 conferences, we collected the data from Google Scholar. For each data set, we computed the proportion of cases whereby the best paper has more citations. We also compare this proportion for years before 2010 and after to evaluate if there is a propaganda effect. Finally, we count the proportion of best papers that are in the top 10% and 20% most cited for each conference instance.

Results

The probability that a best paper will receive more citations than a non best paper is 0.72 (95% CI = 0.66, 0.77) for the Scopus data, and 0.78 (95% CI = 0.74, 0.81) for the Scholar data. There are no significant changes in the probabilities for different years. Also, 51% of the best papers are among the top 10% most cited papers in each conference/year, and 64% of them are among the top 20% most cited.

Discussion

There is strong evidence that the selection of best papers in Computer Science conferences is better than a random selection, and that a significant number of the best papers are among the top cited papers in the conference.     

Patients’ Perceptions of Information and Education for Renal Replacement Therapy: An Independent Survey by the European Kidney Patients' Federation on Information and Support on Renal Replacement Therapy

Background

Selection of an appropriate renal replacement modality is of utmost importance for patients with end stage renal disease. Previous studies showed provision of information to and free modality choice by patients to be suboptimal. Therefore, the European Kidney Patients’ Federation (CEAPIR) explored European patients’ perceptions regarding information, education and involvement on the modality selection process.

Methods

CEAPIR developed a survey, which was disseminated by the national kidney patient organisations in Europe.

Results

In total, 3867 patients from 36 countries completed the survey. Respondents were either on in-centre haemodialysis (53%) or had a functioning graft (38%) at the time of survey. The majority (78%) evaluated the general information about kidney disease and treatment as helpful, but 39% did not recall being told about alternative treatment options than their current one. Respondents were more often satisfied with information provided on in-centre haemodialysis (90%) and transplantation (87%) than with information provided on peritoneal dialysis (79%) or home haemodialysis (61%), and were more satisfied with information from health care professionals vs other sources such as social media. Most (75%) felt they had been involved in treatment selection, 29% perceived they had no free choice. Involvement in modality selection was associated with enhanced satisfaction with treatment (OR 3.13; 95% CI 2.72–3.60). Many respondents (64%) could not remember receiving education on how to manage their kidney disease in daily life. Perceptions on information seem to differ between countries.

Conclusions

Kidney patients reported to be overall satisfied with the information they received on their disease and treatment, although information seemed mostly to have been focused on one modality. Patients involved in modality selection were more satisfied with their treatment. However, in the perception of the patients, the freedom to choose an alternative modality showed room for improvement.     

Developing nation imperatives for a new law of the sea: UNCLOS I and III as stages in the international policy process

Abstract

This paper seeks to compare the two major law of the sea conferences of the post‐World War II period in terms of imperatives for moving toward a more equitable international system. Transitions in the international system which have taken place in the years between the conferences are analyzed, as well as differences in conference participation and procedures. The paper then focuses upon the necessity for policy to be formulated in such a way that imbalances in opportunities for utilization of the seas are redressed. Special attention is given the status of the landlocked and geographically disadvantaged states. The 1977 Negotiating Text is commented on from this perspective. Proposals for development of ocean law/policy in UNCLOS III more congruent with achievement of global equity are then set forth.     

Incidence of Uraemia and Requirements for Maintenance Haemodialysis

The biochemistry laboratory records of a 400-bed general hospital serving a population of about 120,000 showed that during the three-year period 1966-8 inclusive 487 patients had at some stage during their admission a blood urea of 100 mg/100 ml or more. Ninety per cent. were aged 50 or over, 79% were 60 or over, and 52% were 70 or over.The case notes of all patients with renal failure admitted during 1966 and 1967 were examined together with those of patients under 60 admitted during 1968. Three observers agreed about the most likely cause of the renal failure in 90% of patients whose case notes were available, or 74% of the total. The raised blood urea was thought to be due to “prerenal” factors in 60% of the patients, to acute tubular necrosis in 80%, to obstructive uropathy in 12%, and to “intrinsic” renal disease in 20%. Renal failure precipitated by such factors as cardiac failure, chest infections, cerebrovascular accidents, and shock was particularly common in old people.The hospital survey and replies to a questionnaire sent to all general practitioners in the area suggest that in the three-year period 14 patients may have been suitable for treatment by maintenance haemodialysis or renal transplantation. This represents a rate of about 39 per million per year under the age of 60 and 28 per million per year under 50.     

Household Costs of Leprosy Reactions (ENL) in Rural India

Background

Erythema nodosum leprosum (ENL) is a common immune-mediated complication of lepromatous (LL) and borderline lepromatous (BL) leprosy. Most patients experience chronic or multiple acute ENL over many years during an economically active period of their lives. Understanding the economic burden of ENL is essential to provide effective patient support, yet this area has not been investigated.

Methods

Ninety-one patients with LL or BL leprosy attending a leprosy hospital in Purulia district of West Bengal, India, were interviewed using a structured questionnaire. Cases (n = 53) were identified as those who had one or more episodes of ENL within the last 3 years. Controls (n = 38) had LL or BL leprosy but no history of ENL. Data were collected on household income, direct and indirect costs, and coping strategies.

Findings

The total household cost was Rs 1543 per month or 27.9% (IQR 13.2-52.6) of monthly household income for cases, and Rs 237 per month or 4.9% (IQR 1.7-13.4) of monthly household income for controls. Indirect costs accounted for 65% of total household costs for cases. Direct costs accounted for the remaining 35% of household costs, and resulted almost entirely from treatment-seeking in the private sector. Total household costs exceeded 40% of household income for 37.7% of cases (n = 20) and 2.6% of controls (n = 1) [1 USD = 59 INR].

Interpretation

Households affected by ENL face significant economic burden and are at risk of being pushed further into poverty. Health policy should acknowledge the importance of private sector provision and the significant contribution to total household costs of lost productivity (indirect cost). Further work is needed to explore this area and identify solutions.     

Clinical Evaluation of the Oral Contraceptive Use of Norethindrone 5 mg. plus Mestranol 0.075 mg

Norethindrone 5 mg. plus mestranol 0.075 mg., taken daily from menstrual cycle day five through day 24, was used as an oral contraceptive agent in 1248 cycles by 132 clinic patients. One hundred and one patients used this method for six months or more. There were no unplanned pregnancies. Breakthrough bleeding occurred in 38 cycles (3.0% of all cycles). In 25% of 1201 cycles the duration of menstrual flow was shorter than that which had been considered usual for the individual patient involved, and the most common weight change was a gain of 6 to 10 lb.     

Attitudes of general practitioners to prehospital thrombolysis.

OBJECTIVE--To investigate reasons for general practitioners not giving thrombolytic treatment to eligible patients with acute myocardial infarction. DESIGN--Postal questionnaires were sent to 424 general practitioners. SUBJECTS--97 general practitioners who had taken part in the Grampian region early anistreplase trial, 185 whose practices in Scotland were at least 24 km from a district general hospital, and 142 who had attended postgraduate conferences at which thrombolysis had been discussed; 87, 158, and 125 respectively responded. MAIN OUTCOME MEASURES--Answers to questions about readiness to use thrombolytic treatment. RESULTS--Response rate was 87% (370/424). Almost all respondents (350) were convinced of benefits of thrombolysis for acute myocardial infarction, and 277 were convinced that there were additional benefits from its administration in the community at first opportunity. Most doctors working 16 km or more from hospital thought that giving treatment at home would appreciably save time (200/274). Most doctors agreed that they could make time to give thrombolytic treatment (278), and would be willing to record an electrocardiogram (284), and would be able to interpret it (280). Sixty four respondents (17%) reported using thrombolytic treatment in previous year. Among non-users, 150 (49%) were unwilling to use thrombolytic treatment without further training. While many non-users (210 (69%)) were willing to use thrombolytic treatment without encouragement from Department of Health, 184 (60%) were unwilling to use it unless encouraged to do so by their local cardiologist. CONCLUSIONS--The need to become better informed about thrombolysis and lack of encouragement from local cardiologists were important factors preventing wider use of thrombolytic treatment in the community by general practitioners.
