Selection and implementation for coagulation instruments/reagents in a multiple hospital/clinic network.

Selection, standardization, and implementation of instrumentation and reagents throughout a health care facility network can often be a difficult process. However, in today's ever-changing health care setting, it is often mandated. The Veteran's Integrated Systems Network 16 (VISN 16) was faced with such a task early in 1999, with the targeted area being its coagulation laboratories. The plan outlined in this paper was drafted to help facilitate the selection, standardization and implementation of coagulation systems for 17 health care facilities that make up the VISN 16 network. The VISN, encompassing 170,000 square miles, has 10 tertiary care hospitals, six of which have close relationships with affiliate universities. There are 299,733 patients enrolled in this health delivery system. The facilities range from large institutions performing both tertiary and outpatient care to small outpatient clinics. Because of the plan's detailed, comprehensive content, which included analyses of a large number of performance parameters as well as cost-efficiency, the selection process was carried out using a checklist that could be helpful to other organizations selecting equipment and reagents for coagulation studies. An implementation process was devised, resulting in coagulation standardization across the Integrated Health Network.

An evaluation of the Decisional Conflict Scale for measuring the quality of end-of-life decision making.

OBJECTIVE: Researchers and clinicians acknowledge the complexity of planning for future medical treatment desired in the event of incapacitation. Unfortunately, many attempts to evaluate the quality of such difficult planning have been stymied by the lack of measures that can be shown to have validity. This study examines the psychometric characteristics of the Decisional Conflict Scale (DCS) when used as a measure of patients' evaluation of their end-of-life decision-making process. METHODS: This evaluation used the combined data from two independent samples in which 59 outpatients with a life-threatening illness and their surrogate decision makers were assigned to receive, a decision aid intervention, the patient-centered advance care planning (PcACP), or usual care only. RESULTS: Internal consistency for the DCS in the end-of-life decision-making context was high. The DCS demonstrated convergent, construct, and discriminant validity based on the total scale scores. CONCLUSION: The DCS appears to be a viable research instrument for measuring the quality of end-of-life decision making. However, the uncertainty subscale showed a weak discriminating ability and lack of association with the two other subscales, the modifiable factors contributing to uncertainty and the effectiveness of the decision making. PRACTICE IMPLICATIONS: The findings of the study can be useful for measuring decisional conflict in individuals with serious illness facing end-of-life decision making.

Dialyzer best practice: single use or reuse?

Outcome studies have shown either no additional risk or a small additional risk for hospitalization and mortality associated with reprocessing dialyzers. Although the risks from reprocessing dialyzers have yet to be fully elucidated, reuse can be done safely if it is performed in full compliance with the standards of Association for the Advancement of Medical Instrumentation (AAMI). Like most industrial processes, however, complete control of the reuse process in a clinical environment and full compliance with regulations at all times is difficult. Potential errors and breakdowns in the reuse process are continuing concerns. The quality controls for reprocessing of dialyzers are not equal to the rigor of the manufacturing process under the purview of the U.S. Food and Drug Administration (FDA). Therefore, if one were to determine "best practice," single use is preferable to reuse of dialyzers based on medical criteria and risk assessment. The long-term and cumulative effects of exposure to reuse reagents are unknown and there is no compelling medical indication for reprocessing of dialyzers. The major impediment when deciding to convert from reuse to single use of dialyzers is economic. The experience in Fresenius Medical Care-North America (FMCNA) facilities demonstrates that converting from a practice of reuse to single use is achievable. However, the overall economic impact of conversion to single use is provider specific. The dominance of reuse has been negated of late by a major shift in practice toward single use. Physicians and patients should be well informed in making decisions regarding the practice of single use versus reuse of dialyzers.

ComputerLink: the impact of a computer network on Alzheimer's caregivers' decision-making confidence and skill.

1. INTRODUCTION. Decision-making demands faced by homebound caregivers of persons with Alzheimer's Disease (AD) are numerous and complex. Although caregivers frequently know what to do in caring for the person with AD, they lack confidence in their decisions [1]. The challenge of caregiving decisions may be compounded by the lack of resources to aid in decision-making or affirm decisions made. Because many caregivers are homebound, they are unable to avail themselves of traditional health and social services. ComputerLink, computer network, was designed to address the needs of these homebound caregivers. 2. DESCRIPTION. The ComputerLink consisted of a set of specialized programs and utilities residing within a public computer network. The three main features of the ComputerLink, which may provide aid to caregivers in decision making, include: the electronic encyclopedia (EE); a communications utility composed of a question and answer bulletin board (Q&A) and public (Forum) and private mail services; and a decision support module (DSM). The EE contained illness-specific information to support decision-making. The Forum and private mail provided caregivers with a means to interact with peers and professionals about their caregiving decisions. Q&A provided the opportunity to ask questions about caregiving and receive feedback from professionals and peers. The DSM could be accessed to gain information about decision-making or to actually work through a decision problem. The DSM was built on a multi-attribute utility model which employed English-language questions to guide users through a decision analysis. The analysis strategy was designed to help the user focus on the values and trade-offs that occur during difficult choices. The impact of ComputerLink on decision confidence and skill was evaluated as part of a larger randomized experiment. 102 AD caregivers were recruited: 51 caregivers in the control group and 47 in the experimental group completed the 12-month study. The mean age of the caregivers was 60 years. Thirty-three percent were male and 28 percent were Black. The groups did not differ in demographic characteristics. The ComputerLink interface was menu-driven and the system was available 24 hours. ComputerLink use was captured through a passive monitoring system. AD caregivers accessed ComputerLink a total of 3,875 times, with a mean access per individual of 83 (range: 3 - 590). The mean length of an encounter was 13 minutes; subjects typically accessed two or more functions during this time. The decision support model was accessed 91 times. The communication functions were most frequently used (3,724 Forum accesses and 1,888 private mail); the information utility was accessed 518 times. 3. RESULTS. Decision confidence was objectively measured using a modification of the Saunders and Courtney confidence-in-decision making instrument. Caregivers who had access to ComputerLink experienced greater confidence in decision-making than caregivers in the control group (t = 2.73, p < .01). Access to ComputerLink did not alter decision skill as measured by the number of alternative solutions generated for two self-identified decisions problems (t = .18, p < .05). Decision-making confidence correlated positively with ComputerLink accesses (r = .32, p = < .02) and with length of time spent on ComputerLink (r = .30, p = < .02). 56% of the AD caregivers reported that use of ComputerLink increased both their confidence and skill in decision making, though only 38 percent reported using the DSM to make a decision. 4. DISCUSSION. Access to ComputerLink increased decision-making confidence, but not decision-making skill in AD caregivers. The impact of ComputerLink on decision confidence, and not skill, may be related to the differential use of the utilities. (abstract truncated)

Brief report: Training internists in shared decision making about chronic opioid treatment for noncancer pain.

BACKGROUND: The use of chronic opioids for noncancer pain is an increasingly common and difficult problem in primary care. OBJECTIVE: To test the effects on physicians' self-reported attitudes and behavior of a shared decision-making training for opioid treatment of chronic pain. DESIGN: Randomized-controlled trial. PARTICIPANTS: Internal Medicine residents (n=38) and attendings (n=7) were randomized to receive two 1-hour training sessions on a shared decision-making model for opioid treatment for chronic pain (intervention, n=22) or written educational materials (control, n=23). MEASUREMENTS: Questionnaires assessing physician satisfaction, physician patient-centeredness, opioid prescribing practices, and completion rates of patient treatment agreements administered 2 months before and 3 months after training. RESULTS: At follow-up, the intervention group reported significantly greater overall physician satisfaction (P=.002), including subscales on relationship quality (P=.03) and appropriate use of time (P=.02), self-reported completion rates of patient treatment agreements (P=.01), self-reported rates of methadone prescribing (P=.05), and self-reported change in care of patients with chronic pain (P=.01). CONCLUSIONS: Training primary care physicians in the shared decision-making model improves physician satisfaction in caring for patients with chronic pain and promotes the use of patient treatment agreements. Further research is necessary to determine whether this training improves patient satisfaction and outcomes.

Who manages the managers? The 1989 Harvey Cushing oration.

New medical knowledge is emerging at a tremendous rate. Diseases such as Alzheimer's disease. Parkinson's disease, cancer, and others (diseases once considered beyond the scope of medicine) are receiving a great deal of attention. Yet it is a paradox that, at a time when we are learning more about the biology of the human being, it is more difficult to creatively develop the new knowledge into diagnostic tests, surgical interventions, and preventive strategies. The pace of biomedical innovation is being slowed by an increase in the intervention of nonmedical "managers of care." The driving force behind managed care is concern over cost. The managers of medical care have sought to control costs by controlling the doctor's decision making. This is the focus of managed care. The physicians of today, therefore, face a remarkable challenge. They must respond to the needs of patients while being held accountable to an increasing number of overseers in the public and private sectors. These managers of care justify their activities on the notion that the patient will be better off and the cost less if the doctor-patient encounter is regulated by protocols, statistical comparison, utilization review, and fee schedules. While doctor's decisions are being managed by others, who is managing the managers? The answer should be the medical community, principally doctors. Unfortunately, the answer at the moment is the payors--governmental reimbursement agencies, intermediaries, employers, hospitals, or new corporations designed to manage medical costs. The challenge to the physician is to retain the responsibility for those things for which he or she is held accountable. The challenge should not be ignored.

Patients' ideas, fears and expectations of their coronary risk: barriers for primary prevention.

The application of cardiovascular guidelines and risk tables may be impeded by many barriers. In the present paper, we explored the role of patients in the feasibility of cardiovascular preventive care in general practice. Patient-related barriers were examined by means of a qualitative study. Fifteen GPs audio-taped one or two consultations on primary cardiovascular preventive care. The tapes were used to guide the subsequent semi-structured in-depth interviews with patients. Twenty-two patients were interviewed. Patients' understanding of prevention of cardiovascular disease (CVD) was often insufficient. The risk table and the multi-factorial approach were difficult to understand. Risk perception was often unrealistic and dichotomous, and mainly based on personal experiences. There was a demand for more information and cholesterol tests. At the patient level, many barriers impede effective prevention of cardiovascular diseases. In particular, the highly individualized high-risk approach needs to be explained to patients. Educational patient materials, intended to support both the GP and the patient, should take into account the ideas, fears and expectations of patients.

Automated rescreening in cervical cytology. Mathematical models for evaluating overall process sensitivity, specificity and cost.

OBJECTIVE: To develop mathematical models to assist decision makers with the difficult task of evaluating the use of automated rescreening in the process of screening cervical smears. STUDY DESIGN: Using assumptions about incidence, per smear screening costs, and the sensitivity and specificity of cytotechnologists, pathologists and the rescreening device, basic probability models were developed to describe the overall sensitivity, specificity and cost of the screening process. RESULTS: The optimal screening policy is highly dependent on assumptions, and an automated system can significantly affect the overall system cost and accuracy. CONCLUSION: Mathematical planning models are valuable tools to assist decision makers in the design of a screening process for cervical smears.

How to control the risk of novel surgical procedures.

Novel surgical procedures impose particular problems in addition to the general issues of clinical research [1, 7]. Surgical procedures are usually highly technical and therefore difficult to judge by the institutional ethics committee. The ethics committee has therefore to rely on external experts and a relatively large responsibility remains with the surgeon in charge. There are no generally valid regulations regarding new surgical procedures. At our institution, informed consent by the patient, a detailed risk analysis, testing and training in the anatomy/animal lab are required, and in addition a formation/training visit if know-how is available elsewhere. In emergency situations, if during a procedure circumstances call for a new surgical procedure, all the above preconditions cannot be met. A suggested minimum requirement in such a situation is that the decision for a new procedure is achieved by agreement of two board certified specialists. A problem that has to be solved in the future is how to make the negative experiences with new surgical procedures generally available in order to prevent that the same mistakes are repeated in other institutions.

Quality decision making in dialysis.

A patient approaching the final stage of his renal disease is faced with many difficult questions. Should he opt for a transplant or start on dialysis? In the case of dialysis, can he manage his treatment at home or will he need to be cared for in a clinic? Should be choose peritoneal dialysis or haemodialysis? Is the freedom of being independent from a machine, given by CAPD, as valuable as the freedom of having days without treatment, given by HD? The issues are complex and do not have a given answer. To make the proper decisions about his treatment the patient needs extensive information and support from the caregivers. Likewise, the caregivers need to know the patient well in order to give appropriate advice. In this exchange of information, the renal nurse has a very important role. Some patients may need to be dialysed in a hospital but most can get an equally good or even better dialysis treatment in a less stressful environment. A high degree of self-care is preferred by people who value independence and freedom of movement. Self-care also improves the self-confidence and increases the chances of maintaining employment and a rich social life. Self-care could mean both PD and HD, sometimes with the assistance of a spouse or a nurse. But a certain degree of self-care can also be maintained in limited-care centres and satellites, where the presence of nursing staff gives the feeling of security. For everybody involved, not least the purchasers of health care, it is desirable to keep the patients out of the costly hospital environment for as long as possible.

Local information for primary care: the St Albans WAX Project (STAPCIS).

The St. Albans Primary Care Information Service (STAPCIS) is a database of locally focused information designed to be of use for GPs and the Primary Care team as a whole in a particular area. It is currently being used by practices in the St. Albans, Dacorum and Watford & Three Rivers Primary Care Groups. STAPCIS developed from a project initiated in late 1997 to pilot the use of the WAX software to improve access to directory-type and full-text material needed for easy access by primary care staff and traditionally difficult to manage. The database is updated centrally by the STAPCIS Librarian who distributes the new editions to the practices. The WAX software itself was developed by the Cambridge Centre for Clinical Informatics. STAPCIS contains locally and nationally produced relevant information from a variety of sources, including full-text clinical guidelines and directories of Trusts. Decisions on new content are made by a Steering Group and the GPs and Primary Care teams are particularly encouraged to make suggestions regarding new content. The service is financially supported by the three primary care groups. The STAPCIS Librarian is project-managed by the Library & Information Development Unit (North Thames ), which also provides additional equipment and expertise. A new software company, WaX Info Ltd ( ), will soon be releasing a new version of the software, WaX. WaX consists of a WaX client and WaX ActiveLibrary server software. With the new version, the 'books' of information will still be stored on the user's PC, retaining the speed of access, but the server will enable users to 'borrow' books from remote locations and will provide automatic updates of all books. The new software will improve the management and distribution processes of STAPCIS once all of the practices have Internet connectivity.

The development of outpatient Clinical Glidepaths.

For clinicians who are struggling with the complexities of medical decision-making, practice guidelines and evidence-based medicine (EBM) have become increasingly popular and have potential to positively influence the practice of medicine. Nevertheless, they have their limitations. Guidelines are often rigid, based solely on age, and usually do not take into account a patient's comorbidities, life expectancy, and nonmedical preferences. EBM studies may not always include particular patient populations commonly seen by the geriatric clinician (e.g., studies on lipid-lowering agents or antihypertensive drug usually exclude the very old or patients who are frail, demented, or at the end of life). These limitations have made it difficult for geriatric clinicians to use these guidelines because of the need to individualize evaluation and treatment approaches and take into account the varied preferences of their older patients. The purpose of this paper is to present an alternative model of care for geriatric clinicians called The Clinical Glidepaths. The Clinical Glidepaths are outpatient tools intended to assist geriatric clinicians in their decision-making process. They are based on the following principles. (1) Clinicians need guidance concerning many different types of patients, not rigid guidelines based solely on age. (2) EBM should be used but has some limitations of which to be aware. (3) Clinical experience, which emphasizes individual outcomes instead of populations, is an important component of medical decisions. (4) There needs to be room for patient preferences in medical decision-making. (5) An approach to patients based on probable life expectancy and function, instead of age, will be more applicable and useful. (6) Making a useful tool will focus on common problems seen in every day geriatric practices.

Factors affecting feasibility and acceptability of a practice-based educational intervention to support evidence-based prescribing: a qualitative study.

BACKGROUND: Inappropriate and costly GP prescribing is a major problem facing Primary Care Trusts. Educational outreach into practices, alongside other measures, such as audit and feedback, have the potential to enable GP prescribing to become more evidence based. High GP prescribing costs are associated with GPs who see drug company representatives; tend to end consultations with prescriptions; and 'try out' new drugs on an 'ad hoc basis' and use this as evidence of the drug's effect. An educational intervention called 'reflective practice' was developed to meet these and other educational needs. The design of the intervention was informed by studies that have identified the pre-requisites of successful behaviour change in general practice. OBJECTIVES: The study investigated the following: (i) Is it feasible for GPs to attend the sessions included in the educational intervention? (ii) Is the intervention acceptable to the participants and the session facilitators? (iii) What are the barriers to the group educational processes, and how can these be overcome? METHODS: Four practices were recruited in South West England, all of them experiencing problems with prescribing appropriateness and cost. Reflective practice sessions (including a video-taped scenario) were run in each of these practices and qualitative methods were used to explore the complex attitudes and behaviour of the participants. A researcher observed and audio-taped sessions in each practice. At the end of the programme, a sample of doctors and all the facilitators were interviewed about their experiences. The recorded data were transcribed and analysed using standard qualitative methods. RESULTS: The doctors in the largest partnerships were those who had the greatest difficulty in attending the sessions. Elsewhere, doctors were also reluctant to become involved because of previous experience of top-down managerial initiatives about prescribing quality. Facilitators came from a broad range of professional backgrounds. While knowledge of prescribed drug management issues was important, the professional background of the facilitator was less important than group facilitation skills in creating a group process which participating GPs found satisfactory. The video-taped scenario was found to be useful to set the scene for the discussion. Preserving the anonymity of responses of the GPs in the initial stages of the sessions was important in ensuring honesty in the discussion. Reaching a consensus on management of common conditions was sometimes difficult, partly because the use of the term 'best buy' implies economic pressures, rather than benefits to patients, and partly because of the value with which GPs regard the concept of clinical autonomy. 'Reflective Practice' appeared to have the potential to make GPs aware of the link to be made between their clinical management decisions and the evidence provided by the British National Formulary and Clinical Evidence. CONCLUSION: The study indicates the importance of preparing the practice adequately, including providing protected time for all GPs to attend the educational intervention. Scenarios and the structure of the sessions need to make more explicit the links between everyday practice and published evidence of effectiveness. Emphasis on cost-effectiveness may be counterproductive and wider benefits need to be emphasized. We have also identified the skill profile of the facilitator role. Our study indicates a need for a clearer understanding of GPs' perception of clinical autonomy and how this conflicts with the goal of agreement on practice guidelines for treatment. The intervention is now ripe for further development, perhaps by integrating it with other interventions to change professional behaviour. The improved intervention should then be evaluated in a randomized controlled trial.

The cost and efficiency of public and private health care facilities in Ogun State, Nigeria.

During the 1980s, Nigeria faced difficult economic conditions resulting in a severely constrained budget for public health services. To assess more carefully the costs and efficiency of the public and private health sectors, the Federal Ministry of Health in Nigeria undertook a comprehensive survey of health care facilities in Ogun State in 1987, the analysis of which is presented in this study. The findings suggest that there is potential to increase service delivery within existing budgets by more cost-effective allocation of inputs. Many public and private providers are not operating a full technical capacity. It also appears that public facilities are not using cost-minimizing combinations of high and low-level health workers, in particular, too many low-level staff are being used to support high-level workers. The cost analysis indicates that there are short-run increasing returns to scale for inpatient and nearly constant returns to scale for outpatient services. Economies of scope for joint production of inpatient and outpatient services are not being realized. A major implication of such analysis is that improved resource allocation decisions heavily depend on the existence of information systems at the health facility level which carefully integrate financial information with other appropriate and adequate measures of service inputs, health care quality, facility utilization and ultimately health status.

The problem of home management in the estimation of the incidence of acute myocardial infarction from hospital records.

Past studies of the incidence of acute myocardial infarction (AMI) have found information for patients managed at home difficult and expensive to obtain. This study attempted to find whether the efficiency of gathering this information could be improved, or if this group of patients could be neglected entirely. A random sample of 270 doctors in Perth were asked about their management of cases of suspected AMI at home. Of these doctors, 78% said that they never managed AMI at home; excluding such doctors before seeking voluntary notification of new cases managed at home could make population surveys of AMI more efficient. For patients under 65 it was estimated that about 1% or less of non-fatal cases meeting World Health Organization criteria for definite AMI were managed at home. Thus neglecting this group would probably cause little bias in computing incidence rates for AMI in Perth.

Case in point. Counseling about hormone replacement therapy.

Mrs. S's case demonstrates the dilemmas that many women face at menopause regarding HRT. No clear answer to her question exists. Oncology nurses need to help women understand that taking HRT is a decision that is best made after carefully weighing the risks and benefits of therapy. Mrs. S needs to realize that she has some risk factors for heart disease, osteoporosis, breast cancer, and uterine cancer. Depending on her motivation, Mrs. S can modify some of the risk factors (e.g., reducing her weight and cholesterol). Smoking cessation also would reduce her risk for heart disease and, to a lesser extent, osteoporosis. Although her risk for developing breast cancer is higher than for a woman without a family history of breast cancer, she only has one relative who was older when she developed breast cancer. This risk factor in itself probably would not be enough to advise her against taking HRT. Additional testing may offer some clarification. If her breasts are difficult to examine or her mammograms are difficult to interpret, Mrs. S may feel that the risk of missing breast cancer early is too high to justify taking HRT. An abnormal endometrial biopsy also may make Mrs. S decide against taking HRT. BMD testing might help to better assess her risk for osteoporosis. If some bone loss has occurred before menopause, she may want to give more consideration to taking HRT or medications such as alendronate sodium to reduce her risk for an osteoporotic fracture. Women need to understand that, often, no best answer is available to the question of whether or not to take HRT. With every decision comes some consequences. An understanding of risk factors and ways to maximize cardiovascular, breast, endometrial, and bone health are important factors to consider when making an informed decision. Clearly, this is an area where oncology nurses can provide tremendous patient education and support to women making decisions about HRT.

Using the ID3 algorithm to find discrepant diagnoses from laboratory databases of thyroid patients.

Rare cases are a central problem when an expert system is constructed from example cases with machine learning techniques. It is difficult to make a decision support system (DSS) to cover all possible clinical cases. An inductive learning program can be used to construct an expert system for detecting cases that differ from routine cases. The ID3 algorithm and the pessimistic pruning algorithm were tested in this study: a DSS was built directly from the data of patient records. A decision tree was generated, and the cases misclassified by the decision tree as compared with the classifications of a clinician were listed on a checklist, which formed the feedback to the clinician. In clinical situations about 5-10% of functional thyroid disorders may be misclassified. At this error level, the method found over 90% of the errors with a specificity of 95%. In simple medical classification tasks this dynamic self-learning system can be used to create a DSS that can assist in the quality control of clinical decision making.

Designing educational messages to improve weaning food hygiene practices of families living in poverty.

This paper describes a methodology to design feasible interventions to improve weaning food hygiene practices of families living in extreme poverty. Educational messages to promote specific behavioural changes were defined and tested by utilizing a combination of ethnographic, survey and observational methods, and integrating viewpoints and suggestions of mothers and caretakers into the decision-making process. This new approach culminated in a household trial in which five groups, each of 15 non-practising mothers, were invited to adopt defined behaviours (handwashing before and after defined events, boiling water for reconstituting powdered milk, feeding gruel by spoon rather than bottlefeeding, not storing gruels and milks, and all four together). All initiated the advocated behaviours and most (53-80%) sustained the new behaviours and practised them every time during a one-month period. Of the four advocated behaviours, spoon-feeding was the most difficult to adopt wholly. The methodology was developed in response to the high priority given to reducing weaning food contamination for diarrhoeal disease control, and the lack of any existing methodology for defining appropriate educational interventions in resource-poor regions. This approach, with its combination of qualitative and quantitative methods and community focus, is recommended for future studies to design hygiene and other health education interventions in developing countries.
