Best practice treatment algorithm for primary open-angle glaucoma: implications for U.S. ophthalmology practice.

The objective of this study was to develop a "best-practice" treatment algorithm for the management of primary open-angle glaucoma in patients receiving initial medical therapy, to serve as a consideration for future ophthalmology practice. For comparison, a baseline, "common-practice" treatment algorithm was also created that reflects current ophthalmology practice patterns. Survey instruments were developed based on a comprehensive review of relevant literature, along with input from a general ophthalmologist. A panel of eight ophthalmologists subspecialized in glaucoma management was surveyed. Consensus was achieved using a modified Delphi technique. A comparison of common- and best-practice treatment algorithms suggests that in contrast with expert opinion, nonselective beta blockers are currently used more often, and alpha-2 agonists less often, as first-line therapy for the treatment of primary open-angle glaucoma.

Evidence-based guidelines for management of nursing home-acquired pneumonia.

We convened a multidisciplinary, multispecialty panel to develop comprehensive evidence and consensus-based guidelines for managing nursing home-acquired pneumonia. The panel began with explicit criteria for process of care quality measures, performed a comprehensive review of the English-language literature, evaluated the quality of the evidence, and drafted a set of proposed guidelines. The panel reviewed the draft, an annotated bibliography, and data from a study of 30-day survival from nursing home-acquired pneumonia, and then participated in an all-day meeting in January 2001. Using a modified Delphi process, the panel refined the guidelines and developed a care pathway. The guidelines recommend a comprehensive approach, including immunization of staff and residents, and communication between nursing staff and the attending physician within 2 hours of symptom onset. Probable pneumonia was defined. An algorithm was delineated for assessing the patientamprsquos wishes for hospitalization and aggressive care, and deciding on hospitalization based on the severity of the illness as well as the capacity of the nursing home to provide acute care. The timing and extent of evaluation in a nursing home relative to the rapid initiation of antibiotics should depend on whether the patient has any unstable vital signs. An antibiotic covering Streptococcus pneumoniae, Haemophilus influenzae, common gram-negative rods, and Staphylococcus aureus should be given for 10 to 14 days, orally if the patient is able to take medications by mouth.

Critical care competencies.

In the absence of nationally accepted critical care competencies, each educational institution providing critical care programmes is forced to define the essential competencies necessary for practice, leading to variations in expected practice and the emergence of 'postcode' competencies. This research report aims to build upon competency activity for all areas of nursing practice within critical care levels 1, 2 and 3. A functional analysis to elicit core critical care competency statements was conducted and a modified Delphi technique was used to generate consensus opinion from a pan-London purposive sample of nurses working in critical care. The functional analysis group identified four competency statements and elements of competencies. Consensus agreement of 80% was achieved with mean agreement scores that exceed 97%. A core critical care competency framework was refined and developed by expert nurses drawing on their own experience and knowledge of critical care nursing. The framework could be useful to: educationalists designing competency-based curricula; critical care managers as a tool for recruitment and retention and for education and training of staff; individual critical care nurses to facilitate continuous professional development.

Identification of essential elements in the documentation of pharmacist-provided care.

OBJECTIVES: [corrected] To develop guidelines for the documentation elements that need to be included in any record of pharmacist-provided care to allow the quality of the care to be assessed and to describe the use of these guidelines to improve the quality of pharmacist documentation. DESIGN: An initial list of 85 potential documentation elements, developed through a review of the literature, was validated by a group of pharmacy practitioners. Then, through three rounds of a Delphi process and a group meeting, a panel of experts reached consensus on a refined list of 27 documentation data elements. RESULTS: The documentation elements were formatted into a one-page Tool for Evaluation of Documentation (TED). The TED is a checklist for assessing the completeness of the documentation of pharmacist-provided care. CONCLUSION: The TED and the consensus-building methodology used in the development of this tool can serve as cornerstones of a quality assessment process for documentation of pharmacist-provided care, enable further assessment of the quality of care, and, ultimately, be used to measure the impact of pharmacist-provided care on patient outcomes. Our results should provide guidance both to pharmacists providing care and to organizations that assess the quality of that care.

Competency-based health services management education: contemporary issues and emerging challenges.

Health service executives increasingly recognize managerial competencies as an important element of contemporary health services management education and practice. This paper addresses reasons for the growing interestin the topic, provides a brief review of selected literature, and presents findings from two Delphi studies of the identification and use of competencies in health services management. The two studies reveal that there is a high level of agreement among academicians and practitioners concerning which domains of competencies are effectively addressed in health management education, but many still have concerns regarding how the competencies should be applied. The paper concludes with unresolved issues and their implications for future research.

Physicians resources in Lithuania: change comes slowly.

AIM: To analyze the structure of the physician workforce in Lithuania at the time when the country gained independence, changes it has undergone since 1990, and physician resource planning activities. METHODS: National and international databases were examined to determine the changes in the structure of physician workforce after 1990. Studies and reports, funded by international and national governmental organizations, were reviewed to examine the recommendations for physician resource planning and the rate of their acceptance. Since there was no government plan, a study using Delphi technique was conducted to find consensus among practitioners and policy makers on the physician-to-population ratio needed in Lithuania. Medical residents and physicians in Lithuania were surveyed to assess their emigration intentions. RESULTS: In comparison with other Baltic countries, the number of physicians in Lithuania has remained high despite dramatic reductions in the number of students enrolled to medical schools. There is still a maldistribution of physician resources geographically and by specialty. The government has accepted few recommendations based on the international studies. None of the internal databases provided all the needed information on the physician workforce and the existing databases could not be linked to gain access to all required information. CONCLUSIONS: The physician-to-population ratio remained high after Lithuania had gained independence. There has been little planning at the government level to determine the number of physicians needed in a reformed health system. Changes in the number of students admitted to medical schools did not follow from a well thought-out long-term plan for physician workforce the country will need in the future. To develop a frequently updated database of physicians is essential for the successful planning of future physician workforce.

CCORT/CCS quality indicators for congestive heart failure care.

BACKGROUND: Quality indicators are measurement tools for assessing the structure, processes and outcomes of care. Although quality indicators have been developed in other countries, Canadian cardiovascular disease indicators do not exist. OBJECTIVE: To develop quality indicators for measuring and improving congestive heart failure (CHF) care in Canada. METHODS: An 11-member multidisciplinary national expert panel was selected from nominees from national medical organizations. Potential quality indicators were identified by a detailed search of published guidelines, randomized trials and outcomes studies. A two-step modified Delphi process was employed with an initial screening round of indicator ratings, followed by a national quality indicator panel meeting, where definitions of the indicators were developed using consensus methods. Indicators were designed to be measurable, using retrospective chart review and linking existing administrative databases. RESULTS: The case definition criterion was developed based on a discharge diagnosis of CHF (International Classification of Diseases, 9th revision [ICD-9] code 428.x), with diagnostic confirmation using clinical criteria. In total, 29 indicators and five test indicators were recommended. Process indicators included prescription for angiotensin-converting enzyme inhibitors, beta-blockers or warfarin (for atrial fibrillation) at hospital discharge. Nonpharmacological in hospital process indicators included evaluation of left ventricular function, weight measurement and selected patient education counselling instructions. Process indicators in the ambulatory setting included prescription and adherence to drug therapies and physician follow-up. Outcome indicators included mortality, readmissions and emergency visits. CONCLUSIONS: A set of Canadian quality indicators for CHF care encompassing organizational attributes, pharmacotherapy, investigations, counselling, continuity of care and disease outcomes has been developed. These quality indicators will serve as a foundation for future studies evaluating the quality of CHF care in Canada.

Prioritisation of research recommendations from a national needs assessment programme.

OBJECTIVE: To gain consensus on and rank research and development recommendations from a series of Scottish Needs Assessment Programme (SNAP) reports. DESIGN: A two stage Delphi questionnaire was used and participants were asked to rank the recommendations in terms of potential health gain, practicality and priority. SUBJECTS: Views were sought from all consultants in dental public health in Scotland and from non-consultant members of the SNAP oral health steering group. RESULTS: Of the 17 individuals eligible, 16 participated in the study. Fifty four recommendations for research and development were identified in seven SNAP reports. Recommendations relating to the prevention of dental caries in young children, the organisation and delivery of dental care to disadvantaged groups and increased understanding of the aetiology and pathogenesis of oral cancer in younger people were seen as of highest priority. CONCLUSIONS: This study has drawn together and prioritised a series of recommendations, and will help inform future oral health research needs in Scotland.

Does this patient need a narcotic injection? A descriptive analysis of decision making.

Thirty six nurses divided into three groups were asked in a series of three questionnaires to evaluate patients' needs for post-operative narcotic pain relief. Using a decision-analytic procedure, which combined a version of the Delphi technique and the multi-attribute utility approach, the six most salient criteria in order of priority were identified. These criteria were then tested in the clinical situation using a series of scenarios. A difference between how nurses purportedly evaluated patients' needs for narcotic pain relief and what they actually did in hypothetical clinical situations was found. The theoretical implications of these results are discussed.

Preventability of infant mortality in a rural community.

Preventability of infant mortality in a rural southern county was examined with a Delphi technique using case summaries of infant deaths during a selected four-year period. The first two rounds were aimed at developing a consensus of panelists' opinions about problems leading to the high infant mortality rate in the study area. From these opinions, an Infant Mortality Preventability Decision Tree and a Problem List was developed. Panelists used these in Rounds III and IV to evaluate the case summaries. There were significant differences in the preventability ratings between physicians and nurses, indicating the importance of assessing individuals' philosophies of preventability when working with an interdisciplinary team of health care providers.

A consensus report on the use of vacuum-assisted closure in chronic, difficult-to-heal wounds.

Vacuum-assisted closure is an adjunctive therapy that utilizes negative pressure to remove fluid from open wounds through a sealed dressing and tubing which is connected to a collection container. Although introduced into practice for individuals with chronic wounds, evidence to support its use is limited. To compensate for the current gap between the evidence base and the need for best vacuum-assisted closure practices in the treatment of chronic wounds, the existing evidence base (case reports, case series, and studies) for pressure ulcers, diabetic foot ulcers, heel ulcers, and venous leg ulcers was retrieved and tabulated from relevant literature in PubMed and other sources. In addition, expert opinion was obtained through an 11-member Delphi panel of interdisciplinary wound care opinion leaders and educators. The panel included frequent (6) and less-frequent (5) vacuum-assisted closure users. The tabulated responses and the existing literature formed the basis of the best practice statements that serve to guide treatment approaches and stimulate further study.

Cost-effectiveness of becaplermin for nonhealing neuropathic diabetic foot ulcers.

Foot ulcers secondary to peripheral neuropathy and vascular disease are a commonly occurring complication for people with diabetes. Becaplermin, a genetically-engineered growth factor in a hydrogel vehicle, has been shown to be more effective than vehicle-only control in healing chronic foot ulcers of patients with adequate vasculature receiving best clinical care. To evaluate the cost-effectiveness of adding up to 20 weeks of becaplermin to a regimen of best clinical care, a 1-year decision-analytic model was developed and tested using data from a previously published controlled clinical study involving 251 people with diabetes (124 becaplermin/127 control) and adequate vasculature presenting with an infection-free ulcer that had failed to heal despite appropriate therapy. A 20-week healing rate was estimated based on the clinical trial data assuming becaplermin treatment was terminated at 10 weeks in non-responding ulcers, and follow-up data were extended to 1 year. Resource utilization was estimated by an expert panel using a modified Delphi approach. Using the model, it was found that incorporating becaplermin with best clinical care resulted in 26 fewer ulcer-days per patient per year compared to best clinical care alone with an incremental cost-effectiveness ratio of $6 per ulcer-day averted. Results were sensitive to becaplermin cost, efficacy, and effect on infection and recurrence rates. The clinical benefits of becaplermin deserve further investigation to enhance cost-effectiveness information for informed treatment decisions.

[Evaluation and validation of quality care indicators relative to empowerment in complex chronic disease].

The purpose of the study was to identify, validate and rank, through multi-attribute hierarchical analysis, indicators of quality of care related to the empowerment of patients having a chronic complex illness, or their natural care givers. This methodological study was carried within case management and was theoretically based on the quality model of Donabedian (1980) and the empowerment theory of Zimmerman (1995), while also drawing from values underlying nursing practise described by the health promotion model of Allen (1977). Two groups of professional and one group of non professional were considered. Using the DELPHI technique and interviews, the study has 1) provided an evaluation model for quality of care comprising 239 elements (12 main attributes, 75 secondary attributes and 152 indicators), 2) allowed its validation, and 3) its ranking by experts. The discussion encompasses theoretical, empirical and methodological considerations.

Are NHS primary care performance indicator scores acceptable as markers of general practitioner quality?

BACKGROUND: In 2002 the Department of Health published a list of 20 indicators to judge the performance of the 302 primary care organisations (PCOs) in England during 2001-2002. General practitioners (GPs) have expressed doubts about the relevance, applicability and evidence base of these indicators for actual practice. AIMS: To fashion NHS performance indicators to be acceptable and relevant to practicing GPs. DESIGN OF STUDY: A Delphi technique followed by simple mathematical modelling. METHODS: We asked a group of 24 senior GP educators to place the Department of Health performance indicators in rank order as markers of quality in general practice. We found just seven indicators comprised 73% of the markers chosen and all seven were chosen by over three-quarters of the responders. Using a simple 'sign test' system, we then calculated a composite points score for all 302 PCOs. RESULTS: We found that there were almost twice as many PCOs at the upper and lower ends of performance and fewer in the middle than we predicted theoretically. The results suggest that pan-PCO or practice factors account for the low performance scores of 16 of 35 PCOs with extremely poor performance and for the high scores of 17 of the 36 PCOs with extremely high performance. CONCLUSION: We have developed a method that shows how numerous Department of Health performance indicators can be merged into a single composite performance score. We show that this composite performance score is easy to derive, simple to interpret, is acceptable to GPs, and has face validity.

Development of clinical practice guidelines: evaluation of 2 methods.

The aim of this study was to compare 2 methods for developing a clinical practice guideline (CPG) on the management of asymptomatic, impacted mandibular third molars. Outcome measures were the mean time invested by the participants for each method, the quality of the CPGs measured using the Appraisal of Guidelines for Research and Evaluation (AGREE) indicator and observations of the group discussions. We used a national consensus procedure following the Rand modified Delphi procedure (2 panels) and a local consensus procedure (2 existing dental peer groups). The mean time spent was about equal for the 2 methods. The quality of the CPGs developed by the expert panels was higher than that of the CPGs developed by the dental peer groups. Observation indicated that all group processes were influenced by the chairperson. We concluded that the expert panel method is suitable for developing reliable CPGs on a national or regional level.

[A research on the public health index related to the comprehensive assessment on floods].

OBJECTIVE: To develop a public health index related to the comprehensive assessment on the impact caused by floods. METHODS: A Analytic hierarchy process (AHP) theory was used to establish the initial evaluation system on the impact of floods. Modified-Delphi process was used to screen and determine the indicators and their weights while synthetical scored method was used to establish the comprehensive assessment model. Percentile was used to differentiate the degree of floods. Finally, analysis of variance (ANOVA) and correlation analysis were used to test the differentiability of the model for different degree of floods and the independence of these indicators. RESULTS: The model of comprehensive assessment on the impact of floods was set up, including six first-ranking indicators and twenty-four sub-indicators. The values of comprehensive assessment were divided into five grades by the percentiles. Verified results indicated that there were significant difference among the five grades (F = 76.11, P < 0.01) and all indicators were independent. CONCLUSION: An index of comprehensive assessment on the impact of floods was established, which could be used to evaluate the impact of floods and to differentiate the degree of flood, which seemed to have the characteristic of reliability, comprehensiveness and practicability.

Feasibility of quality indicators for the management of geriatric syndromes in nursing home residents.

PURPOSE: The assessment and management of dementia, falls and mobility disorders, malnutrition, end-of-life issues, pressure ulcers, and urinary incontinence have been identified as important quality improvement targets for vulnerable elders residing in nursing homes. This study aimed to identify valid and feasible measures of specific care processes associated with improved outcomes for these conditions. METHODS: Nine experts in nursing home (NH) care participated in a modified Delphi process to evaluate potential quality indicators (QIs) for care in NHs. Panelists met and discussed potential indicators before completing confidential ballots rating validity (process associated with improved outcomes), feasibility of measurement (with charts or interviews), feasibility of implementation (given staffing resources in average community NHs), and importance (expected benefit and prevalence in NHs). The NH panel's median votes were used to identify a final set of QIs that were subsequently reviewed by a clinical oversight committee. RESULTS: Sixty-eight geriatric syndrome QIs were identified as valid and important in NH populations. Panelists assessed 12 (18%) of these QIs as having questionable feasibility to implement in average community nursing homes trying to provide quality care. Nine (13%) would not be included in systems assessing quality of care for persons with advanced dementia or poor prognosis. CONCLUSIONS: Steps of care critical to the assessment and management of geriatric syndromes in NHs were identified. Feasibility is an important issue for a significant number of these, indicating that much remains to be done to design systems that efficiently and reliably implement these care processes.

Preliminary criteria for clinical remission for select categories of juvenile idiopathic arthritis.

OBJECTIVE: To develop preliminary criteria for inactive disease and clinical remission for select categories of juvenile idiopathic arthritis (JIA), and to decide what such clinical states should predict in terms of probability of disease recurrence. METHODS: A Delphi serial questionnaire consensus-formation approach was used initially to gather criteria in use by pediatric rheumatologists (PR) for defining clinical remission in oligoarticular (persistent and extended), rheumatoid factor (RF) positive and negative polyarticular, and systemic JIA. Results from sequential questionnaires provided an agenda for a nominal group technique (NGT) conference to reach consensus on unresolved questions. RESULTS: One hundred and thirty PR from 34 countries responded to the questionnaires and 20 PR from 9 countries attended the conference. Draft criteria for inactive disease include the following: no active arthritis; no fever, rash, serositis, splenomegaly, or generalized lymphadenopathy attributable to JIA; no active uveitis; normal erythrocyte sedimentation rate or C-reactive protein; and a physician's global assessment of disease activity rated at the best score possible for the instrument used. According to consensus vote, 6 continuous months of inactive disease on medication defines clinical remission on medication, while 12 months of inactive disease off all anti-arthritis (and anti-uveitis) medications defines clinical remission off medication. The finalized criteria for remission off medication ideally should predict that a patient has </= 20% probability of disease recurrence within the next 5 years. CONCLUSION: Using consensus formation techniques, we formulated preliminary criteria for inactive disease and clinical remission on and off medication for use in select categories of JIA. Retrospective validation is in progress; prospective validation will follow. Future efforts will include other categories of JIA.
