MEDICAL PLANNING FOR DISASTER—Brief Résumé of Accomplishments in California 1950-1959

Extensive accumulation and dispersal of medical supplies and equipment has been carried out in this state since 1950. Although such medical supplies and equipment are inadequate for an all out war type disaster their addition to the medical disaster preparedness program represents a great contribution and efforts must be made to continually supplement them.All hospitals must have a disaster plan which is well understood and which must be tested by actual test exercises at least once each year.Preparations for major disasters of all types are costly and time-consuming but represent one of the best possible investments which we can make as insurance against the loss of thousands of casualties.It is the responsibility of each physician to prepare himself and his family in anticipation of being exposed to natural or man-made disasters.

Prenatal care: a comparative evaluation of nurse-midwives and family physicians

We review various organ procurement strategies from ethical and practical perspectives to understand why these strategies have been relatively unsuccessful. We propose that the CMA recommend the implementation of a required-request policy in hospitals. We also propose a possible new approach in which people from the age of 18 years would voluntarily enrol in an organ donation program, agreeing to permit all usable organs to be taken for transplantation at the time of death. In return they would have priority for receiving organs made available by the program. We believe that this program would save lives, respect the donor''s autonomy and satisfy the principles of justice and beneficence.     

University acknowledges special risks,introduces drug program for anesthetists.

Anesthetists are at special risk for becoming addicted to some of the drugs they work with. The problem was highlighted by the recent death of a physician in Comox, BC, and a doctor''s brush with death at a hospital near Ottawa. The University of Ottawa has responded with a program, the professional Assistance Program for the Impaired or Disabled Physician, that is in the final stages of approval. Although it will be aimed initially at anesthetists and anesthesia residents in the university''s teaching hospitals, there are hopes the program will spread eventually to other medical departments.     

Emergency Health Planning

This paper outlines the development of emergency health planning as a function of government. Ten provinces have the basic responsibility for the organization, preparation and operation of medical, nursing, hospital and public health services in an emergency. The Department of National Health and Welfare is responsible for the provision of advice and assistance to the provincial and municipal governments in such matters. Eight provinces have now hired full-time planning staffs to co-ordinate the health planning of the Provincial Departments of Health and Provincial Emergency Measures Organization.Four major programs have been established. The first program provides for the continuity of leadership and guidance by health authorities at the federal, provincial and municipal level. Essential records have been developed and emergency legislation prepared. This program, however, will be of little use unless health services are organized at the municipal level. In this organizational program, advice and assistance have been provided to existing hospitals and departments of health in the conduct of disaster planning. The efforts of these agencies are co-ordinated by municipal health authorities into a community disaster plan. The third program deals with information and education of the general public and the health workers. This program is designed to make the family unit self-sufficient for up to seven days and the health worker prepared to undertake his emergency role. The first three programs are directed to the organization and training of manpower; the fourth program provides the necessary supplies. From the national medical stockpile of $18,000,000, some $12,000,000 has been received, packaged for long-term storage and distributed to regional depots across the country. To ensure their ready availability in time of emergency an agreement has been reached with seven provinces for the release of hospital disaster kits.     

John P. Peters and the committee of 430 physicians

John Peters and his committee had a few basic goals. One was that local, state, and federal governments needed to provide money to construct facilities, support medical research and education, and care for the poor. And they wanted experts to call the shots. Over time, Peters and the committee got what they wanted for the most part: Hill-Burton money for building the hospitals, the rise of the National Institutes of Health, Medicare, Medicaid, a Veterans Administration system, and new and expanded medical schools. The experts calling the shots included David Kessler at the Food and Drug Administration and Surgeon General C. Everett Koop. In the halcyon days of American health system reform, back in 1993, Yale''s Paul Beeson wrote about the Committee of 430 Physicians and its goals in the Pharos of Alpha Omega Alpha. Beeson was optimistic and he quoted from my 1991 JAMA health system reform editorial as a sharp contrast to what Fishbein had written - although coincidentally, we both quote Lincoln. My editorial began, "''with malice toward none, with charity for all...'' so spoke Abraham Lincoln in his second inaugural address recognizing that he had no political consensus regarding either the constitutionality of states seceding or the morality of slavery being abolished. Nonetheless, he knew what was right and was able, through persuasive, often inspiring rhetoric, to conclude a bloody and decisive Civil War and constitute the foundation for this great republic.... Yet access to basic medical care for all of our inhabitants is still not a reality in this country. There are many reasons for this, not the least of which is a long-standing, systematic, institutionalized racial discrimination.... An aura of inevitablitiy is upon us. It is not acceptable morally, ethically, or economically for so many of our people to be medically uninsured or seriously underinsured. We can solve this problem. We have the knowledge and the resources, the skills, the time, and the moral prescience. We need only clear-cut objectives and proper organization of existing resources. Have we now the national will and leadership?" Beeson''s answer to that question in 1993 was, "Yes, but not by one comprehensive act." He quoted Peters from his 1938 Annals of Internal Medicine article: "a sweeping program suddenly imposed in this country as a whole out of the head of any Jove would undoubtedly create confusion if not chaos. Thoughtful investigation and experiment promises more than grandiose projects born of emotional preconceptions. The programs must be built of an evolutionary manner, step by step." Very wise, very valid. But how long must our people wait?     

Radiation Protection in Canada: Part III. * The Role of the Radiation Protection Division in Safeguarding the Health of the Public

The current status of radiation protection in Canada is discussed in the last of a three-part series. Particular emphasis has been placed on the role of the Radiation Protection Division of the Department of National Health and Welfare. A radioactive fallout study program has been established involving the systematic collection of air and precipitation samples from 24 locations, soil samples from 23 locations, fresh-milk samples from 16 locations, wheat samples from nine areas and human-bone specimens from various hospitals throughout Canada. A whole-body-counting facility and a special study of fallout in Northern areas have also been initiated. For any age group, the highest average strontium-90 concentration in human bone so far reported has been less than four picocuries per gram of calcium compared with the maximum permissible level of 67 derived from the International Committee on Radiation Protection (ICRP) recommendations. By the end of 1963 a general downward trend of levels of radioactivity detected in other parts of the program has been observed. Programs to assess the contribution to the radiation exposure of members of the population from medical x-rays, nuclear reactor operations and natural background-radiation sources have also been described. The annual genetically significant dose from diagnostic x-ray examinations in Canadian public hospitals has been estimated to be 25.8 mrem. Results from the reactor-environment monitoring programs have not suggested the presence of radioactivity beyond that contributed from fallout.     

A survey of medical quality assurance programs in Ontario hospitals.

OBJECTIVE: To determine the prevalence and types of medical quality assurance practices in Ontario hospitals. DESIGN: Survey. SETTING: All teaching, community, chronic care, rehabilitation and psychiatric hospitals that were members of the Ontario Hospital Association as of May 1990. PARTICIPANTS: The person deemed by the chief executive officer of each hospital to be most responsible for medical administration. INTERVENTION: A questionnaire to obtain information on each hospital''s use of criteria audit, indicators inventory, occurrence screening and reporting, and utilization review and management (URM) activities. OUTCOME MEASURES: Prevalence of the use of the quality assurance activities, the people responsible for the activities and the relative success of the URM program in modifying physicians'' performance. RESULTS: Of the 245 member hospitals participants from 179 (73%) responded. Criteria audits were performed in 136 (76%), indicators inventory in 43 (24%), occurrence screening in 44 (25%), occurrence reporting in 61 (34%) and URM in 123 (69%). In-hospital deaths were reviewed in 157 (88%) of the hospitals. In all, 87 (55%) of the respondents from hospitals that had a URM program or were developing one indicated that their program was successful in modifying physicians'' practices, and 29 (18%) reported that it was not successful; 26 (16%) stated that the effect was still unknown, and 16 (10%) did not respond. Seventy (40%) stated that results of tissue reviews were reported at least 10 times per year and 94 (83%) that medical record reviews were reported at least as often. The differences in the prevalence of the quality assurance activities between the hospitals were not found to be significant. CONCLUSIONS: Many Ontario hospitals are conducting a wide variety of quality assurance activities. Further study is required to determine whether the differences in prevalence of these activities between hospitals would be significant in a larger, perhaps national, sample. Strategies are needed to ensure universal involvement and participation in the improvement of the quality of care and the assessment of the cost-effectiveness of health care treatments. Recommendations to achieve these objectives are suggested.     

REPORT FROM OTTAWA

In a national disaster, the medical profession would lose physicians and auxiliary personnel and would need assistance. Canada''s 22,000 physicians and 85,000 nurses are located for the most part in potential target areas. Survivors among Canada''s 6396 dentists could supply 30% reinforcement. The dentist''s training, his manual dexterity and experience acquired in the management of hemorrhage, shock, débridement, suturing, reduction and immobilization of fractures, and control of pain and infection would be valuable. Additional functions he could perform would be first-aid, including but not limited to artificial respiration, early management of chest wounds, preparation of casualties for movement, and assistance in general surgical procedures. Dentists with special training in anesthesia, oral surgery or public health could be of particular value in relieving anesthetists, surgeons, radiologists and public health officers of some of their duties. Joint training of physicians and dentists in mass casualty care could increase the efficiency of the team work in disaster and is being considered by many medical and dental faculties.     

Extramural Continuing Medical Education

The experience of one Faculty of Medicine in developing programs of continuing medical education in community hospitals is presented. After mention of the importance of regular reading of the medical literature, and the problems created by its growing volume, the necessity of supplementary programs in community hospitals is pointed out. The different patterns of community hospital meetings that evolved to meet various circumstances in the Atlantic Provinces are detailed. A “course” consisting of six weekly evening meetings, followed by morning case presentations and discussions, has proved the most successful form of continuing medical education in community hospitals. Better than half the doctors in the community attend, and active participation is the rule. The importance of advance planning, the techniques of advance planning, and the expense of operating the program are listed. A projection is made that 46 such courses would be required to cover the four Atlantic Provinces adequately, with a staff equivalent to eight full-time teachers and a budget in excess of $200,000. The fact that this is only 7.5% of Canada''s medical population indicates the magnitude of the unmet needs of continuing medical education in this country.     

Medicaid and the Mainstream: Reassessment in the Context of the Taxpayer Revolt

California''s Medicaid program—Medi-Cal—attempted to implement the ideal of mainstream medical care for the poor by giving program beneficiaries a “credit card” for use in the private health care marketplace. This exposed the program to the perverse economic incentives of the fee-for-service, costplus health care system, and contributed to a high rate of increase in program costs. Attempts to control costs have been equally perverse, resulting in low payment rates, the second-guessing of physician professional judgments, the probing of medical and fiscal records, and the use of computerized surveillance systems.Attempts to shift to the use of more efficient delivery systems have had small success. Attempts to attain cost containment through restructuring the Medi-Cal program have been rejected in the name of the mainstream ideal. Costs have continued to escalate, with annual increases as high as 20 percent in some years. Medi-Cal now costs $4 billion per year, the largest single program in California state government.The taxpayer revolt in California is creating a fiscal crisis that will force rethinking of the premises of publicly funded health care for the poor, and a restructuring of strategies for reaching that objective. In the short run, it appears that the issue may not be whether the indigent will have access to mainstream medical care, but whether they will have access to any medical care. In the longer run, the crisis should represent an opportunity for building a system of health care that can serve the financially disadvantaged at a cost tolerable to our society.     

Development of a program model to evaluate the potential for reuse of single-use medical devices: results of a pilot test study

Single-use medical devices (SUDs, or disposables) have become a major expense in hospital budgets. The need for cost reduction and the availability of sterilization technologies other than the autoclave have prompted hospitals worldwide to begin reusing disposables, in many cases without proper assessment of the true costs (time, personnel, etc) and ease/difficulty of implementation of an institutional reuse program. Our group has developed a rigorous program model to evaluate SUDs for reuse. The program comprises 3 sequential protocols: (1) device audit, (2) laboratory evaluation, and (3) clinical evaluation. Use of this model can produce scientific and financial data sufficient for any institution interested in reuse to reach an initial decision about its feasibility. In addition to the testing outcomes, regulatory requirements, the position of manufacturers and third-party reprocessors, and legal and ethical concerns must be considered. A successful reuse program must include ongoing evaluations to ensure that the safety levels and cost savings established during the initial audit and evaluation phases continue. Herein, we give the rationale and details of our program model and discuss results of our pilot application of the "ideal" protocol in a real-world context.     

Hospitals' response to the buckle-up baby legislation in Ontario.

Drivers in Ontario are legally responsible to ensure that infants and toddlers are restrained in a child safety seat or by a lap belt. In 1982 the minister of health sent a memorandum to all medical officers of health and the administrators and medical directors of all public hospitals in Ontario, urging them to encourage and assist parents in protecting their newborn children with safety seats. In 1983 the Toronto General Hospital established the Cooperative Hospital Infant Restraint Program (CHIRP) to study the feasibility of a "loaner" program for hospitals in metropolitan Toronto. The authors describe CHIRP and its objectives. They also report the results of a questionnaire they sent in 1984 to all Ontario hospitals that had a newborn or pediatric service to assess their response to the minister''s memorandum.

The New Quality Assurance Standard of the Joint Commission on Accreditation of Hospitals

The Joint Commission on Accreditation of Hospitals (JCAH) has continuously emphasized improvement in the quality of care provided in hospitals as the central purpose of the accreditation process. In striving to assure such improvement, the JCAH has stressed the need for, and the responsibility of, the medical and other professional staffs to provide continuing review and evaluation of patient care. In recent years, quality assessment activities have evolved, proliferated and matured to the extent that they require a purposeful integration if they are to effect sustained improvement in patient care and clinical performance. To assist hospitals in the coordination or integration of quality assessment activities, the Board of Commissioners of the JCAH has approved an important new quality assurance standard.Significant requirements of the new standard are a comprehensive quality assurance program, a written plan, a problem-focused approach to the review and evaluation of patient care and clinical performance, an annual reassessment of the program, and an improvement in patient care or clinical performance. The new standard reflects the JCAH belief that an integrated, problem-focused approach to quality assurance will significantly improve the quality of care provided throughout a hospital. Such an approach recognizes the interdependence of hospital departments and services in the provision of patient care, and, therefore, requires a purposeful integration or coordination of quality assessment data and activities. Consequently, quality assessment data may be utilized effectively and efficiently, and many potentially useless or duplicative quality assessment activities can be eliminated. The new standard affords hospitals considerable flexibility in the manner in which they implement and administer the program and encourages innovation.     

A Review of the Deep Learning Methods for Medical Images Super Resolution Problems

Super resolution problems are widely discussed in medical imaging. Spatial resolution of medical images are not sufficient due to the constraints such as image acquisition time, low irradiation dose or hardware limits. To address these problems, different super resolution methods have been proposed, such as optimization or learning-based approaches. Recently, deep learning methods become a thriving technology and are developing at an exponential speed. We think it is necessary to write a review to present the current situation of deep learning in medical imaging super resolution. In this paper, we first briefly introduce deep learning methods, then present a number of important deep learning approaches to solve super resolution problems, different architectures as well as up-sampling operations will be introduced. Afterwards, we focus on the applications of deep learning methods in medical imaging super resolution problems, the challenges to overcome will be presented as well.     

Cost of achieving a balance in the anaesthetic department of a district general hospital.

In Achieving a Balance the Department of Health published requirements for medical staffing in hospitals. To review the effect that these would be likely to have a study was undertaken in the anaesthetic department of a district general hospital. The results were then validated with staffing levels in a new district general hospital with only one tier of junior staff. It was found that over the next 10 years a massive expansion in the numbers of consultants would be needed at a cost of 108,000 pounds in salaries and employer''s contributions alone.     

Selection of Patients for Coronary Artery Bypass Operations

Bypass operations have proved to be an effective treatment for advanced coronary artery disease. Randomized clinical trials have now shown that compared with medical treatment, bypass operations enhance survival in patients who have three-vessel disease or left main coronary stenosis. The goals of both medical and surgical treatment should be to improve a patient''s quality of life, extend survival and reduce medical care costs. Preliminary data suggest that bypass operations may be less costly than medical treatment in patients with severe angina that requires repeated or prolonged stays in hospital.     

Exercise therapy for prevention of falls in people with Parkinson's disease: A protocol for a randomised controlled trial and economic evaluation

Background

People with Parkinson's disease are twice as likely to be recurrent fallers compared to other older people. As these falls have devastating consequences, there is an urgent need to identify and test innovative interventions with the potential to reduce falls in people with Parkinson's disease. The main objective of this randomised controlled trial is to determine whether fall rates can be reduced in people with Parkinson's disease using exercise targeting three potentially remediable risk factors for falls (reduced balance, reduced leg muscle strength and freezing of gait). In addition we will establish the cost effectiveness of the exercise program from the health provider's perspective.

Methods/Design

230 community-dwelling participants with idiopathic Parkinson's disease will be recruited. Eligible participants will also have a history of falls or be identified as being at risk of falls on assessment. Participants will be randomly allocated to a usual-care control group or an intervention group which will undertake weight-bearing balance and strengthening exercises and use cueing strategies to address freezing of gait. The intervention group will choose between the home-based or support group-based mode of the program. Participants in both groups will receive standardized falls prevention advice. The primary outcome measure will be fall rates. Participants will record falls and medical interventions in a diary for the duration of the 6-month intervention period. Secondary measures include the Parkinson's Disease Falls Risk Score, maximal leg muscle strength, standing balance, the Short Physical Performance Battery, freezing of gait, health and well being, habitual physical activity and positive and negative affect schedule.

Discussion

No adequately powered studies have investigated exercise interventions aimed at reducing falls in people with Parkinson's disease. This trial will determine the effectiveness of the exercise intervention in reducing falls and its cost effectiveness. This pragmatic program, if found to be effective, has the potential to be implemented within existing community services.

Trial registration

The protocol for this study is registered with the Australian New Zealand Clinical Trials Registry (ACTRN12608000303347).
