Prescribing at the hospital-general practice interface. I: Hospital outpatient dispensing policies in England.

OBJECTIVE--To describe the outpatient dispensing policies of major acute hospitals in England. DESIGN--Postal questionnaire survey in November 1990. SETTING--All (278) major acute hospitals in England with more than 250 beds, excluding maternity, paediatric, or psychiatric hospitals; nine hospitals declined. PARTICIPANTS--Hospital chief pharmacists. MAIN OUTCOME MEASURES--Current dispensing policy and exceptions to it; when the policy was formed; and who was involved in its formation. RESULTS--Completed questionnaires were received from 200 (72%) of the hospitals approached. The quantities of drugs dispensed to outpatients ranged from zero in 12 hospitals to unlimited amounts in nine; nearly half (92) dispensed a 14 days'' supply of drugs. The greater the restriction on outpatient dispensing, the more recently the policy had been introduced (chi 2 for trend = 7.15; df = 1; p less than 0.01). Permissible exceptions to the policy included the consultant''s specific request (134 hospitals), difficulty in obtaining drugs in the community (102), urgent need for start of treatment (49), and certain types of patients (41) or drugs or their regimens (104). Groups who were neither represented on the hospital committee concerned with policy formation nor consulted before policy changes included regional health authorities in 122 hospitals, district health authorities in 101 hospitals, and general practitioners in 32 hospitals. CONCLUSIONS--Outpatient dispensing policies varied considerably among the hospitals surveyed, but they seemed to be moving towards greater restrictions on the supply of drugs given to outpatients.     

Current trends in the cardiovascular clinical trial arena (I)

The existence of effective therapies for most cardiovascular disease states, coupled with increased requirements that potential benefits of new drugs be evaluated on clinical rather than surrogate endpoints, makes it increasingly difficult to substantiate any incremental improvements in efficacy that these new drugs might offer. Compounding the problem is the highly controversial issue of comparing new agents with placebos rather than active pharmaceuticals in drug efficacy trials. Despite the recent consensus that placebos may be used ethically in well-defined, justifiable circumstances, the problem persists, in part because of increased scrutiny by ethics committees but also because of considerable lingering disagreement regarding the propriety and scientific value of placebo-controlled trials (and trials of antihypertensive drugs in particular).The disagreement also substantially affects the most viable alternative to placebo-controlled trials: actively controlled equivalence/noninferiority trials. To a great extent, this situation was prompted by numerous previous trials of this type that were marked by fundamental methodological flaws and consequent false claims, inconsistencies, and potential harm to patients.As the development and use of generic drugs continue to escalate, along with concurrent pressure to control medical costs by substituting less-expensive therapies for established ones, any claim that a new drug, intervention, or therapy is "equivalent" to another should not be accepted without close scrutiny. Adherence to proper methods in conducting studies of equivalence will help investigators to avoid false claims and inconsistencies. These matters will be addressed in the third article of this three-part series.     

New procedures affecting the conduct of clinical trials in the United Kingdom.

Changes have recently been introduced to facilitate the conduct of clinical trials of new drugs in the United Kingdom. These changes became necessary because early developmental work on new drugs was going abroad to the detriment of British industry and with a loss of skill in our departments of clinical pharmacology. The scheme also gives formal recognition to the part played by ethics committees in considering approval of the ethical aspects of clinical trials of new drugs.     

A critical analysis of Australian clinical ethics committees and the functions they serve

The predominant function of Australian clinical ethics committees (CECs) is policy formation. Some committees have an educational role. Few committees play any direct role in advising on ethics in the management of individual patients and this occurs only in exceptional circumstances. There is a tendency to exaggerate both the number and function of committees. It is suggested that studies of ethics committees, based on questionnaire surveys, should be interpreted cautiously. An examination of ethical issues indicates that there is a role for a critical analysis of power relations in Australian hospitals that is not fulfilled by CECs.     

Barriers and challenges in clinical ethics consultations: the experiences of nine clinical ethics committees

Clinical ethics committees have recently been established in nearly all Norwegian hospital trusts. One important task for these committees is clinical ethics consultations. This qualitative study explores significant barriers confronting the ethics committees in providing such consultation services. The interviews with the committees indicate that there is a substantial need for clinical ethics support services and, in general, the committee members expressed a great deal of enthusiasm for the committee work. They also reported, however, that tendencies to evade moral disagreement, conflict, and 'outsiders' are common in the hospitals. Sometimes even the committees comply with some of these tendencies. The committees agree that there is a need to improve their routines and procedures, clarify the committees' profile and field of responsibility, to make the committees well-known, to secure adequate operating conditions, and to develop organizational integration and support. Various strategies to meet these challenges on a local, regional or national level are also explored in this paper.     

The Canadian Paediatric Society: its early years.

The Canadian Paediatric Society has continued since its origin to be a consultative organization and has been recognized as the official voice for children in matters relating to health. It has appointed a number of special committees to study and recommend policy and action to the profession, government and other health bodies as new developments in child health have become important in Canada. The dedicated involvement of so many fellows of the society makes it apparent that in its nearly 60 years of existence it has lived up to the objectives of its founders.     

Death after Taking Medicaments

A register of reported adverse reactions, recently made available to major hospitals and medical schools gives an indication of prescribing habits under the N.H.S. in England and Wales. An analysis is made here of the chief medicaments allegedly leading to death. Such data are incomplete because of lack of knowledge of the total use of each drug in the United Kingdom and because reporting of adverse reactions is very incomplete. Nevertheless, data about various groups of drugs do draw attention to some hazards and should encourage more widespread reporting of reactions to drugs and other medicaments.     

加强药事管理委员会在药物合理应用中作用的探索

近年来医疗技术水平迅速发展,新药品的种类、剂型不断更新,但随之而来医疗服务费用快速上升,而其中药品费用更是首当其冲。从节约医疗资源为更广大的患者服务的角度来考虑,降低药占比规范药品合理使用,就是公立医院解决“看病难、看病贵”的重要管理节点。因此,通过药事委员会的监测、分析、决策、问责等作用的落实,充分发挥医院药事管理及药物治疗学委员会的领导作用显得尤为重要。     

FORENSIC OBSTETRICS

Some of the more important and current aspects of forensic obstetrics are, broadly,1. Fulfillment of basic criteria in all cases of alleged traumatic abortion.2. Utilization of therapeutic abortion review boards, as well as sterilization committees, in all hospitals, with the active support of such committees by all those physicians interested in advancing the art and practice of obstetrics.3. Early and active joint study of professional liability problems by combined groups of physicians and lawyers in every community.     

Antibiotic Self-Prescribing Trends,Experiences and Attitudes in Upper Respiratory Tract Infection among Pharmacy and Non-Pharmacy Students: A Study from Lahore

Pharmacists are the custodians of drugs; hence their education, training, behaviors and experiences would affect the future use of drugs at community and hospital pharmacies. Therefore, we aimed at evaluating the self-prescribing antibiotic trends, knowledge and attitudes among pharmacy and non-pharmacy students. We found that pharmacy students had higher risks of experiencing URIs related symptoms such as cough (RR; 1.7, p = 0.002), allergy (RR; 2.07, p = 0.03) and running nose (RR; 3.17, p<0.005), compared to non-pharmacy students -resulting in higher probabilities of selecting cough syrups (OR; 2.3, p<0.005), anti-histamines (OR; 1.8, p = 0.036) and anti-inflammatory/anti-pyretic (OR; 2.4, p<0.005) drugs. Likewise, bachelor’s degree pupils (OR; 2, p = 0.045), urban area residents (OR; 2.44; p = 0.002) and pharmacy students (OR; 2.9, p<0.005) exhibited higher propensities of antibiotic self-use–notable classes include, b-lactams (45.9%) followed by macrolides (26.5%) and augmentin (28.94%), respectively. Surprisingly, pharmacy and non-pharmacy students had higher odds of using antibiotics in common cold (OR; 3.2, p<0.005) and pain (OR; 2.37, p = 0.015), respectively. Unlike non-pharmacy students, pharmacy students were likely to select alternative therapy, such as Joshanda (OR; 2.22, p = 0.011) and were well acquainted with antibiotic hazards, with 77% reduction in risk of antibiotics re-use. In conclusion, university students exhibited antibiotic self-prescribing trends in conditions that does not warrant their use, thus are irrational users. The pharmacy education confers very little benefit to rational self-prescribing practices among students, while non-pharmacy students are more vulnerable to repeated antibiotic usage. Thus, the educational and training modules should be designed for university students to disseminate targeted information regarding the potential hazards of antibiotic self-use and importance of consultation with qualified and registered medical doctor/pharmacist before starting with antibiotics.     

Translating research findings into practice - the implementation of kangaroo mother care in Ghana

ABSTRACT: BACKGROUND: Kangaroo mother care (KMC) is a safe and effective method of caring for low birth weight infants and is promoted for its potential to improve newborn survival. Many countries find it difficult to take KMC to scale in healthcare facilities providing newborn care. KMC Ghana was an initiative to scale up KMC in four regions in Ghana. Research findings from two outreach trials in South Africa informed the design of the initiative. Two key points of departure were to equip healthcare facilities that conduct deliveries with the necessary skills for KMC practice and to single out KMC for special attention instead of embedding it in other newborn care initiatives. This paper describes the contextualisation and practical application of previous research findings and the results of monitoring the progress of the implementation of KMC in Ghana. METHODS: A three-phase outreach intervention was adapted from previous research findings to suit the local setting. A more structured system of KMC regional steering committees was introduced to drive the process and take the initiative forward. During Phase I, health workers in regions and districts were oriented in KMC and received basic support for the management of the outreach. Phase II entailed the strengthening of the regional steering committees. Phase III comprised a more formal assessment, utilising a previously validated KMC progressmonitoring instrument. RESULTS: Twenty-six out of 38 hospitals (68 %) scored over 10 out of 30 and had reached the level of 'evidence of practice' by the end of Phase III. Seven hospitals exceeded expected performance by scoring at the level of 'evidence of routine and institutionalised practice.' The collective mean score for all participating hospitals was 12.07. Hospitals that had attained baby-friendly status or had been re-accredited in the five years before the intervention scored significantly better than the rest, with a mean score of 14.64. CONCLUSION: The KMC Ghana initiative demonstrated how research findings regarding successful outreach for the implementation of KMC could be transferred to a different context by making context-appropriate adaptations to the model.     

Evaluation of genotoxic effects induced by exposure to antineoplastic drugs in lymphocytes and exfoliated buccal cells of oncology nurses and pharmacy employees

The continuous introduction of new antineoplastic drugs and their use as complex mixture emphasize the need to carry out correct health risk assessment. The aim of this study was to evaluate genotoxic effects of antineoplastic drugs in nurses (n=25) and pharmacy technicians (n=5) employed in an oncology hospital. The nurses administered antineoplastic drugs in the day-care hospital (n=12) and in the wards (n=13), and pharmacy technicians prepared the drugs in the central pharmacy. We performed the micronucleus (MN) test with lymphocytes and exfoliated buccal cells and conducted traditional analysis of chromosomal aberrations (CA). Thirty healthy subjects were selected as controls. Monitoring of surface contamination with cyclophosphamide, 5-fluorouracil, ifosfamide, cytarabine, and gemcitabine showed the presence of detectable levels only for cyclophosphamide, 5-fluorouracil and ifosfamide. In addition, we measured the 5-fluorouracil metabolite alpha-F-betaalanine in the urine of all subjects and found significant concentrations only in 3 out of 25 nurses. The micronucleus assay with lymphocytes did not show significant differences between exposed and control groups, while the same test with exfoliated buccal cells found higher values in nurses administering antineoplastic drugs than in pharmacy employees. In the CA analysis, we detected in exposed groups a significant increase (about 2.5-fold) of structural CA, particularly breaks (up to 5.0-fold). Our results confirm the genotoxic effect of antineoplastic drugs in circulating blood lymphocytes. Moreover, in exfoliated buccal cells the data show more consistent genetic damage induced during administration of the antineoplastic drugs than during their preparation. The data also stress the use of this non-invasive sampling, to assess occupational exposure to mixture of chemicals at low doses.

Contribution of general practitioner hospitals in England and Wales.

A survey of a one-in-seven sample of general practitioner hospitals in England and Wales, performed to determine the contribution they make to overall hospital work load and the attitudes of the general practitioners working in them, showed that 3% of acute hospital beds in England and Wales were in general practitioner hospitals, which provided initial hospital care for up to 20% of the population. Altogether 16% of general practitioners and 22% of consultants were on the staffs, and they coped with more than 13% of all casualties, 6% of operations, and 4% of x-ray examinations. Nearly a million casualties were treated at no cost to the National Health Service. Twenty new district general hospitals would be needed to cope with the work load currently dealt with by general practitioner hospitals. The results of this survey indicate that these smaller hospitals deal efficiently and cheaply with their work load, and that morale is high. General practitioner hospitals could have an important part to play in providing certain types of care, but there are no financial incentives to enable general practitioners to realise this potential fully.     

ISCT survey on hospital practices to support externally manufactured investigational cell-gene therapy products

There is considerable interest in the next generation of personalized medicine, especially cell and gene therapy products such as chimeric antigen receptor T cells (CAR-Ts). Unlike other small molecules or pharmacologic drugs, most existing cell or cell-based gene therapy products (CGTs) require apheresis collection of the patient or donor, subsequent manufacture of the product, and final shipment of the product to the clinical site for infusion. Whereas traditional pharmaceutical drugs have involved the drug sponsor and the clinical site and clinical pharmacy, this new manufacturing paradigm has evolved, in many cases, to include an apheresis center, a cell processing lab, the sponsor's manufacturing facility, and a clinical site with or without a pharmacy. Here we report the results of a survey of current practices handling investigational CGTs conducted by the Immuno-Gene Therapy committee of the International Society of Cell and Gene Therapy.
