Paediatric Day Case Tonsillectomy - Audit of a New Programme

Aims The primary objective of this audit was to assess 30-day unplanned admission or readmission rates following day case tonsillectomy. Secondary objectives included assessing demographic characteristics of patients and surgical and anaesthetic techniques employed. Methods Retrospective chart review was performed. Results 34 tonsillectomies or adenotonsillectomies were performed for children aged between 5 and 17 years. A total of six patients (17.6%) were either admitted from the day ward or readmitted within 30 days. This was not statistically significantly greater than the maximum acceptable rate of 15% as recommended by ENT UK and the Royal College of Surgeons (95% confidence intervals 4.8% - 30.5%, p = 0.33). Of these admissions, one (2.9%) was due to nausea and inadequate oral intake, one (2.9%) was due to clinical concerns regarding sleep apnoea and four readmissions (11.8%) were due to bleeding. Anaesthesia techniques used varied considerably. Conclusion Further multidisciplinary co-operation and standardisation of care may help to improve this programme and reduce unplanned admission and readmission rates.

Faculty Perceptions of Entrustable Professional Activities to Determine Pharmacy Student Readiness for Advanced Practice Experiences

Objective. To quantify pharmacy faculty members' perceptions of the importance of entrustable professional activities (EPAs) and the expected level of entrustment that should be achieved to determine APPE readiness. Methods. Entrustable professional activities define the core skills and tasks expected of new pharmacy graduates and may serve as a logical framework for determining pharmacy student readiness to begin advanced pharmacy practice experiences (APPEs). A five-question survey was distributed to all faculty members, staff members, and administrators at Ferris State University College of Pharmacy. Respondents were asked to rate 18 statements mapped to 12 EPAs on the perceived importance of each statement and the expected level of entrustment students should achieve to determine readiness for APPEs. Thresholds were used to determine consensus for importance and level of entrustment for each statement. Results. Of the 44 faculty members surveyed, 28 (63.6%) responded. A strong consensus was reached on the level of importance for 16 of 18 statements (89%), while two statements demonstrated moderate consensus (11%). No strong consensus was identified on levels of entrustment. Seven (39%) of 18 statements demonstrated moderate entrustment consensus and 11 (61%) statements demonstrated little consensus. Conclusion. Strong consensus was identified regarding which EPAs are important to determine students' APPE readiness; however, no strong consensus was found when evaluating levels of entrustment. Lack of consensus regarding entrustment raises several questions that require further study and clarification as the implementation of EPAs continues throughout the Academy.

Estimating the public health impact of a national guideline on cervical cancer screening: an audit study of a program in Campinas, Brazil

BACKGROUND

A Brazilian guideline on cervical cancer screening was released in 2011. The objective was to verify changes in screening indicators around this period.

METHODS

An audit study which sample was all screening tests performed by the public health system of Campinas city from 2010 to 2016. Variables were absolute tests numbers, excess tests, intervals and results, by age. For trend analysis was used Cochran-Armitage × 2 and linear regression.

RESULTS

Were carried out 62,925 tests in 2010 and 43,523 tests in 2016, a tendency at a reduction (P = 0.001). Excess tests were higher than 50% over the years, with a tendency at a reduction (P < 0.001). Tests performed on women under 25 ranged from 20.2 to 15.4% in the period (P < 0.001), while in the 25-64 years age-group, it ranged from 75.1 to 80.2% (P < 0.001). In 2010 the most frequent interval was annual (47.5%) and in 2016 biennial (34.7%). There was a tendency at a reduction in the proportion of tests performed at the first time and those with an annual interval (P < 0.001), and also a tendency at an increase in tests with intervals equal to or greater than biannual (P < 0.001). We observed a tendency at a reduction in LSIL and HSIL-CIN2 results (P = 0.04 and P = 0.001, respectively), and a tendency at an increase in HSIL-CIN3 result (P = 0.02).

CONCLUSION

The proportion of cervical cancer screening tests performed out of the recommendation showed a significant reduction in the period. This indicates a tendency to align cervical cancer screening in Campinas with the standards recommended.

The Effects of Environmental Factors on the Efficiency of Clinical Commissioning Groups in England: A Data Envelopment Analysis

Clinical Commissioning Groups (CCGs) were created in 2013 to make the NHS more responsive, efficient and accountable. A large number of different indicators can be used to measure the quality and outcomes of services provided by CCGs, however there is currently no single measure of overall efficiency available. The performance of CCGs may also be confounded by environmental factors such as deprivation, population size and burden of disease. Data Envelopment Analysis (DEA) is a linear programming technique that can be used to measure the relative efficiency of a given set of organisations. To use DEA to measure the efficiency of English CCGs and assess the impact of environmental factors. This study estimates the technical efficiency of 208 CCGs in England using DEA. The inputs and outputs used include budget allocation, number of general practitioners, mortality rates, patient satisfaction and Quality and Outcomes Framework achievement scores. Regression analysis is used to assess the effects of environmental factors on efficiency, such as population size, prevalence of disease, and socio-economic status. Twenty-three percent (47/208) of CCGs were efficient compared to the others. Three environmental factors were statistically significant predictors of efficiency: CCGs with smaller population sizes were more efficient than those with larger ones, while high unemployment rates and a high prevalence of chronic obstructive pulmonary disease led to a decrease in efficiency scores. Comparative deprivation was not a significant predictor of efficiency. The finding that the relationship between deprivation and efficiency is not statistically significant suggests that NHS England’s adjustment for environmental factors within the CCG-level budget allocation is broadly successful. This study shows the potential of DEA for assessing technical efficiency at CCG-level in the English NHS.

The development of entrustable professional activities for internal medicine residency training: a report from the Education Redesign Committee of the Alliance for Academic Internal Medicine

PURPOSE

The Alliance for Academic Internal Medicine charged its Education Redesign Committee with the task of assisting internal medicine residency program directors in meeting the challenges of competency-based assessment that were part of the Accreditation Council for Graduate Medical Education's (ACGME's) Next Accreditation System.

METHOD

Recognizing the limitations of the ACGME general competencies as an organizing framework for assessment and the inability of the milestones to provide the needed context for faculty to assess residents' competence, the Education Redesign Committee in 2011 adopted the work-based assessment framework of entrustable professional activities (EPAs). The committee selected the EPA framework after reviewing the literature on competency-based education and EPAs and consulting with experts in evaluation and assessment. The committee used an iterative approach with broad-based feedback from multiple sources, including program directors, training institutions, medical organizations, and specialty societies, to develop a set of EPAs that together define the core of the internal medicine profession.

RESULTS

The resulting 16 EPAs are those activities expected of a resident who is ready to enter unsupervised practice, and they provide a starting point from which training programs could develop assessments and curricula. The committee also provided a strategy for the use of these EPAs in competency-based evaluation.

CONCLUSIONS

These EPAs are intended to serve as a starting point or guide for program directors to begin developing meaningful, work-based assessments that inform the evaluation of residents' competence.

Admission and discharge practices: High Dependency Unit audit outcome

This paper presents the findings of a retrospective audit of admission and discharge practices of a nurse led High Dependency Unit (Nurse Specials Unit) in Perth, Western Australia. The aim of the study was: to review the effectiveness of the inclusion and exclusion guidelines for patients admitted to the Nurse Special Unit (NSU); to identify characteristics of admitted patients; and to determine the level of adherence to admission protocols for documentation of patient condition, plan of care, medical and Clinical Nurse Consultant review. The sample comprised all patients admitted to the NSU from September 2004 - March 2005, excluding those (50) in the pilot study (n = 154). This audit revealed patients were primarily elderly and admitted for close nursing supervision. Inclusion and exclusion criterion were adhered to, however documentation of patient data, in relation to current status and plan of care, was poorly completed and frequently absent during intra hospital transfer. This lack of clear documentation poses a significant risk to the patient. Further research is required to determine strategies that result in appropriate and useful transfer documentation. In addition, the content of transfer data that permits continuity of care needs to be determined.

Audit uncovers weak skill mix

More than a quarter of hospital wards in Wales do not have the nursing skill mix recommended by the chief nursing officer, according to an audit.

Associations between the organisation of stroke services, process of care, and mortality in England: prospective cohort study

OBJECTIVE

To estimate the relations between the organisation of stroke services, process measures of care quality, and 30 day mortality in patients admitted with acute ischaemic stroke.

DESIGN

Prospective cohort study.

SETTING

Hospitals (n=106) admitting patients with acute stroke in England and participating in the Stroke Improvement National Audit Programme and 2010 Sentinel Stroke Audit.

PARTICIPANTS

36,197 adults admitted with acute ischaemic stroke to a participating hospital from 1 April 2010 to 30 November 2011.

MAIN OUTCOME MEASURE

Associations between process of care (the assessments, interventions, and treatments that patients receive) and 30 day all cause mortality, adjusting for patient level characteristics. Process of care was measured using six individual measures of stroke care and summarised into an overall quality score.

RESULTS

Of 36,197 patients admitted with acute ischaemic stroke, 25,904 (71.6%) were eligible to receive all six care processes. Patients admitted to stroke services with high organisational scores were more likely to receive most (5 or 6) of the six care processes. Three of the individual processes were associated with reduced mortality, including two care bundles: review by a stroke consultant within 24 hours of admission (adjusted odds ratio 0.86, 95%confidence interval 0.78 to 0.96), nutrition screening and formal swallow assessment within 72 hours (0.83, 0.72 to 0.96), and antiplatelet therapy and adequate fluid and nutrition for first the 72 hours (0.55, 0.49 to 0.61). Receipt of five or six care processes was associated with lower mortality compared with receipt of 0-4 in both multilevel (0.74, 0.66 to 0.83) and instrumental variable analyses (0.62, 0.46 to 0.83).

CONCLUSIONS

Patients admitted to stroke services with higher levels of organisation are more likely to receive high quality care as measured by audited process measures of acute stroke care. Those patients receiving high quality care have a reduced risk of death in the 30 days after stroke, adjusting for patient characteristics and controlling for selection bias.

Health workers, health facilities and penile cutting in papua new guinea: implications for male circumcision as an HIV prevention strategy

There has been increasing interest in Papua New Guinea (PNG) in male circumcision (MC) for HIV (human immunodeficiency virus) prevention following compelling evidence from ecological studies and clinical trials in Africa, and the World Health Organization's recommendation in 2007 that MC be considered part of comprehensive HIV prevention programs in high-prevalence settings. Though no national policy has been established in PNG, East Sepik Province (ESP) commenced a formal program of MC in 2006, and there is evidence that PNG health workers are involved in other penile foreskin cutting activities in many areas. As part of a wider Male Circumcision Acceptability and Impact Study in PNG, we conducted an audit at a sample of PNG health facilities to assess their suitability for implementing a national MC program, and to identify issues that may arise in any future roll-out. The clinical audits demonstrated the difficulties with procurement and availability of equipment for general services around PNG, shortage of staff and capacity, and limitations of available clinical space. Results show that the ESP program has been successful; however, the success relies heavily on commitment from key workers to volunteer their time and services. A review of penile cutting activities by health care workers outside of the ESP program showed that the PNG health system is already involved in contemporary and traditional penile cutting practices via formal and informal arrangements: for example, by responding to complications from penile cuts performed by non-health workers, assisting community members to perform penile cutting through provision of equipment and advice, or providing regular penile foreskin cutting services for contemporary and traditional practices.

Reduction of severe acute maternal morbidity and maternal mortality in Thyolo District, Malawi: the impact of obstetric audit

BACKGROUND

Critical incident audit and feedback are recommended interventions to improve the quality of obstetric care. To evaluate the effect of audit at district level in Thyolo, Malawi, we assessed the incidence of facility-based severe maternal complications (severe acute maternal morbidity (SAMM) and maternal mortality) during two years of audit and feedback.

METHODOLOGY/PRINCIPAL FINDINGS

Between September 2007 and September 2009, we included all cases of maternal mortality and SAMM that occurred in Thyolo District Hospital, the main referral facility in the area, using validated disease-specific criteria. During two- to three-weekly audit sessions, health workers and managers identified substandard care factors. Resulting recommendations were implemented and followed up. Feedback was given during subsequent sessions. A linear regression analysis was performed on facility-based severe maternal complications. During the two-year study period, 386 women were included: 46 died and 340 sustained SAMM, giving a case fatality rate of 11.9%. Forty-five cases out of the 386 inclusions were audited in plenary with hospital staff. There was a reduction of 3.1 women with severe maternal complications per 1000 deliveries in the district health facilities, from 13.5 per 1000 deliveries in the beginning to 10.4 per 1000 deliveries at the end of the study period. The incidence of uterine rupture and major obstetric hemorrhage reduced considerably (from 3.5 to 0.2 and from 5.9 to 2.6 per 1000 facility deliveries respectively).

CONCLUSIONS

Our findings indicate that audit and feedback have the potential to reduce serious maternal complications including maternal mortality. Complications like major hemorrhage and uterine rupture that require relatively straightforward intrapartum emergency management are easier to reduce than those which require uptake of improved antenatal care (eclampsia) or timely intravenous medication or HIV-treatment (peripartum infections).

The Stroke Practice Improvement Network: a quasiexperimental trial of a multifaceted intervention to improve quality

OBJECTIVE

The aim of this project was to determine whether a tailored multifaceted intervention aimed at site-specific barriers is more effective than audit feedback alone for improving adherence to inhospital stroke performance measures (PMs): door to needle time of less than 1 hour for tissue plasminogen activator, dysphagia screening, deep venous thrombosis prophylaxis, and warfarin treatment for atrial fibrillation.

METHODS

Hospitals were paired on baseline adherence to dysphagia screening and quality improvement infrastructure and randomized to receive audit feedback alone (n=7) versus audit feedback plus site-specific interventions (n=6). Data were collected on all admitted patients with stroke seen in the neurology department before and after a 6-month implementation period. The primary end point was the difference in postintervention adherence rates for each PM, except tissue plasminogen activator because of low sample size.

RESULTS

Data were collected on 2071 preintervention patients and 1240 postintervention patients. Targeted site-specific interventions, such as standing orders and standardized dysphagia screens, were imperfectly implemented during the 6-month intervention period. For atrial fibrillation, the intervention group had an 11% higher postintervention adherence rate beyond that of the control group (98% v 87%, P < .005). No other statistically significant changes in PM adherence were observed.

CONCLUSION

Implementation of site-specific interventions for quality improvement of specific measures in stroke was difficult to achieve in a 6-month time frame and led to improved adherence for only one of 3 PMs. Studies with a longer intervention period and more sites are required to determine whether tailored interventions can enhance stroke improvement.

Crossing professional boundaries: nurse-led catheter insertion

The steady expansion of nursing roles is enabling staff to perform tasks traditionally undertaken by doctors. This change is perceived as being in the interests of patients, particularly because it can reduce waiting times, but it can also increase job satisfaction and enhance opportunities for the recruitment and retention of staff. This article describes the establishment of a nurse-led service for tunnelled central venous catheter insertion for renal dialysis. The result of a retrospective audit describes what impact this service has had.

Use of the bacteriology laboratory to decrease general practitioners’ antibiotic prescribing

OBJECTIVE

Use of the bacteriology laboratory to guide antibiotic prescribing in primary care is often considered inappropriate due to difficulties of access in a relevant time scale. The overnight analysis offered to general practitioners in the Grampian area of Scotland for the past 6 years (ABLE), and which had previously been shown to reduce antibiotic prescribing by two-thirds in a randomized controlled trial, was audited to see if it was being used correctly in general practice, that is to reduce unnecessary antibiotic prescribing.

METHODS

699 consultations were audited. Of these, 357 were ABLE patients. The other 342 were chosen because an antibiotic had been prescribed.

RESULTS

Only 36.7% (140) of the ABLE patients were prescribed an antibiotic, 65.7% being given a delayed action script. All but 10 were culture positive. ABLE patients had a greater proportion of urinary tract infections than the non-ABLE patients, but less lower-respiratory and skin or soft-tissue infection. The antibiotics prescribed reflected the differences in infection type. The repeat visit rate and repeat antibiotic prescription rate were almost identical between the two groups.

CONCLUSION

While the overall use of ABLE in Grampian is low, its use seems to be appropriate in that it is successfully being used to identify bacterial infection and reduce unnecessary antibiotic prescribing.

The Oncosurge strategy for the management of colorectal liver metastases – An external validation study

INTRODUCTION

Because most patients with colorectal liver metastases (CRLM) present to general surgeons and oncologists without a specialist interest in their management, a computer program (OncoSurge) has been created that identifies individual patient resectability and recommends optimal treatment strategies. The aim of this study was to validate the Oncosurge strategy by comparing its recommendations with the decisions made by a multidisciplinary (MDT) meeting, in a supra-regional hepatobiliary referral centre, using real cases with known outcomes.

METHODS

We reviewed the records and imaging of 98 consecutive patients with CRLM, who had been referred for decision making to our MDT meeting between January 1, 2004 and December 31, 2004. All patient and tumour characteristics were entered onto the Oncosurge decision model, which was accessed at www.evidis.com/oncosurge/

RESULTS

There was concordance between Oncosurge and MDT decisions in 93/98 cases. The observed kappa (kappa) was 0.850 (95% CI: 0.728-0.972). In descriptive terms, a kappa score greater than 0.8 equates to "almost perfect agreement".

CONCLUSIONS

Our results demonstrate the validity of the Oncosurge system when compared to one year of decision making in an established hepatobiliary MDT meeting. This confirms the utility of the Oncosurge system for decision making, audit and educational purposes.

The impact of a citywide audit with educational intervention on the care of patients with epilepsy

The care of patients with epilepsy historically has been well documented to be poor. Previous attempts to improve care through education have been unsuccessful. The New GP Contract in the UK introduced epilepsy as a core quality indicator from April 2004. This prospective audit assesses the impact of an audit with educational intervention on the process of care of patients with epilepsy. The case notes of 610 patients, of all ages, with epilepsy on treatment, in 13 general practices serving Chester and surrounding area were reviewed before and 2 years after an intervention, comprising (a) the provision of a comprehensive template, (b) individualised categorisation for each patient and (c) an educational session led by a Neurologist. The overall review rate increased in the first year from 41 to 49% (p<0.0001) and by 2 years to 63% (p<0.0001). Documented remission rate increased from 29 to 43% (p<0.0001). Admissions to accident and emergency fell significantly (p=0.0026). There was no fall in the non-compliance rate. Forty five percent of patients with documented poor control were not under shared care. Issues highlighted in the audit generated 77 referrals. There were clear health gains in 62 (13%) individuals from referrals and practice interventions related to the audit. This original audit identified significant improvements in review rate, documented remission rate and beneficial outcomes in individual patients. The changes were attributable to both the educational intervention and the coincidental acceptance of the New GP Contract. Remaining problems include lack of shared care for patients with active epilepsy.

Audit system on quality of breast cancer diagnosis and treatment (QT): results of quality indicators on screen-detected lesions in Italy in 2005 and preliminary results for 2006

Within this survey, conducted by the Italian Group of Mammography Screening (GISMa), individual data are collected yearly on more than 50% of all screen-detected operated lesions in Italy. In 2005, results showed overall good diagnosis and treatment quality, and an improving trend over time. Critical issues were identified in waiting times, compliance with the recommendations on not performing frozen section examination on small lesions and on performing specimen X-ray. Pre-operative diagnosis has reached the acceptable target, but room for improvement still exists. The sentinel lymph node technique (SLN) was performed on the axilla in more than 70% of screen-detected invasive cancers, avoiding a large number of potentially harmful dissections. On the other hand, potential overuse of SLN deserves further investigation. The detailed results have been distributed to local and regional screening programmes in order to allow multidisciplinary discussion and the identification of appropriate solutions to any problems documented by the data. Specialist Breast Units with adequate case volume would provide the best setting for making audit effective in producing quality improvement.

Bridging the gap between evidence and practice in venous thromboembolism prophylaxis: the quality improvement process

Venous thromboembolism (VTE) is considered to be the most common preventable cause of hospital-related death. Hospitalized patients undergoing major Surgery and hospitalized patients with acute medical illness have an increased risk of VTE. Although there is overwhelming evidence for the need and efficacy of VTE prophylaxis in patients at risk, only about a third of those who are at risk of VTE receive appropriate prophylaxis. To address the shortfall in VTE prophylaxis, the US Joint Commission and the National Quality Forum (NQF) endorse standardized VTE prophylaxis practices, and are identifying and testing measures to monitor these standards. Hospitals in the USA accredited by Centers for Medicare and Medicaid Services to receive medicare patients will need VTE prophylaxis programs in place to conform to these national consensus standards. This review aims to give background information on initiatives to improve the prevention of VTE and to identify key features of a successful quality improvement strategy for prevention of VTE in the hospital. A literature review shows that the key features of effective quality improvement strategies includes an active strategy, a multifaceted approach, and a continuous iterative process of audit and feedback. Risk assessment models may be helpful for deciding which patients should receive prophylaxis and for matching VTE risk with the appropriate intensity of prophylaxis. This approach should assist in implementing the NQF/Joint Commission-endorsed standards, as well as increase the use of appropriate VTE prophylaxis.

Inadequate analgesic prescription increases secondary post-tonsillectomy bleed rates: a completed audit loop

A significantly greater than normal secondary haemorrhage rate was noted in patients who had undergone tonsillectomy or adenotonsillectomy as waiting list 'initiative' cases within an alternative healthcare provider setting, compared with patients undergoing the same surgery within a primary healthcare trust (17.8 vs 3.9 per cent, respectively; p 0.1). We conclude that adequate analgesia, for the first week post-tonsillectomy, is essential in order to keep the secondary haemorrhage rate within an acceptable range.

Utility of the PFA-100 as a screening test of platelet function: an audit of haemostasis laboratories in Australia and New Zealand

The PFA-100 is a relatively new laboratory instrument, first described in 1995. There have since been numerous studies assessing its utility as a screening tool for platelet dysfunction and/or von Willebrand's disease (VWD). The PFA-100 displays variable sensitivity to different types of platelet disorders, as well as to antiplatelet medication (e.g. aspirin), with similar caveats for monitoring of primary haemostasis-promoting therapies in platelet dysfunction. There is therefore considerable uncertainty regarding its utility within this context, and we have accordingly performed an audit of usage among participants of the Royal College of Pathologists of Australasia Quality Assurance Program. Of 105 laboratories surveyed, 40 responded that they performed platelet function testing, with 26 (65%) further indicating they utilized the PFA-100. We report a wide variety of laboratory usage among these users, including numbers of tests performed [annual median (range) = 270 (15-6000)], sources of requests (clinical sources and localities), testing criteria and follow-up action. Most tests were completed within 4 h of collection, as recommended by the manufacturer, and most tests were performed as a replacement, or as a preliminary screen of platelet function (i.e. classical aggregation). Most abnormal findings, however, were attributed to antiplatelet medication such as aspirin.

Student dietitians? attitudes towards research and audit: a comparison with registered dietitians

BACKGROUND

Student dietitians' attitudes towards research and audit are important as they are likely to influence their subsequent involvement in such activities once qualified. The aim of this study was to investigate the attitudes of student dietitians towards research and audit and to compare them with those of registered dietitians previously reported.

METHODS

A questionnaire survey of final-year student dietitians' attitudes towards research and audit was conducted. Students indicated their agreement with 12 statements relating to research and audit and the results were compared with those from an identical survey of registered dietitians.

RESULTS

A total of 110 questionnaires were completed (87% response rate). In general, students had positive attitudes towards research and audit. The majority (91%) agreed that 'all dietitians should be able to act on research', whilst only a small minority agreed that research (6%) and audit (4%) was 'not part of a dietitian's role'. In general, students had more positive attitudes towards research, and less positive attitudes towards audit, than dietitians from a previously published survey.

DISCUSSION

Final year student dietitians have positive attitudes towards research and audit. These should be nurtured throughout the early years of their career in order to maximize on their research potential.

Comparison of Clinical and Administrative Data Sources for Hospital Coronary Artery Bypass Graft Surgery Report Cards

Background— Regardless of statistical methodology, public performance report cards must use the highest-quality validated data, preferably from a prospectively maintained clinical database. Using logistic regression and hierarchical models, we compared hospital cardiac surgery profiling results based on clinical data with those derived from contemporaneous administrative data.

Methods and Results— Fiscal year 2003 isolated coronary artery bypass grafting surgery results based on an audited and validated Massachusetts clinical registry were compared with those derived from a contemporaneous state administrative database, the latter using the inclusion/exclusion criteria and risk model of the Agency for Healthcare Research and Quality. There was a 27.4% disparity in isolated coronary artery bypass grafting surgery volume (4440 clinical, 5657 administrative), a 0.83% difference in observed in-hospital mortality (2.05% versus 2.88%), corresponding differences in risk-adjusted mortality calculated by various statistical methodologies, and 1 hospital classified as an outlier only with the administrative data–based approach. The discrepancies in volumes and risk-adjusted mortality were most notable for higher-volume programs that presumably perform a higher proportion of combined procedures that were misclassified as isolated coronary artery bypass grafting surgery in the administrative cohort. Subsequent analyses of a patient cohort common to both databases revealed the smoothing effect of hierarchical models, a 9% relative difference in mortality (2.21% versus 2.03%) resulting from nonstandardized mortality end points, and 1 hospital classified as an outlier using logistic regression but not using hierarchical regression.

Conclusions— Cardiac surgery report cards using administrative data are problematic compared with those derived from audited and validated clinical data, primarily because of case misclassification and nonstandardized end points.

The utility of an automated electronic system to monitor and audit transfusion practice

BACKGROUND AND OBJECTIVES

Transfusion laboratories with transfusion committees have a responsibility to monitor transfusion practice and generate improvements in clinical decision-making and red cell usage. However, this can be problematic and expensive because data cannot be readily extracted from most laboratory information systems. To overcome this problem, we developed and introduced a system to electronically extract and collate extensive amounts of data from two laboratory information systems and to link it with ICD10 clinical codes in a new database using standard information technology.

MATERIALS AND METHODS

Three data files were generated from two laboratory information systems, ULTRA (version 3.2) and TM, using standard information technology scripts. These were patient pre- and post-transfusion haemoglobin, blood group and antibody screen, and cross match and transfusion data. These data together with ICD10 codes for surgical cases were imported into an MS ACCESS database and linked by means of a unique laboratory number. Queries were then run to extract the relevant information and processed in Microsoft Excel for graphical presentation. We assessed the utility of this data extraction system to audit transfusion practice in a 600-bed adult tertiary hospital over an 18-month period.

RESULTS

A total of 52 MB of data were extracted from the two laboratory information systems for the 18-month period and together with 2.0 MB theatre ICD10 data enabled case-specific transfusion information to be generated. The audit evaluated 15,992 blood group and antibody screens, 25,344 cross-matched red cell units and 15,455 transfused red cell units. Data evaluated included cross-matched to transfusion ratios and pre- and post-transfusion haemoglobin levels for a range of clinical diagnoses. Data showed significant differences between clinical units and by ICD10 code.

CONCLUSION

This method to electronically extract large amounts of data and linkage with clinical databases has provided a powerful and sustainable tool for monitoring transfusion practice. It has been successfully used to identify areas requiring education, training and clinical guidance and allows for comparison with national haemoglobin-based transfusion guidelines.

Behandlungsfehler im Zusammenhang mit der Bestimmung des prostataspezifischen Antigens

Advances in prostate specific antigen (PSA) diagnosis are accompanied by deficits in realization. The justification of claims by affected patients against their doctors are reviewed by commissions of experts and mediation by medical councils out of court, impartial and free of charge. The objectivity of the review is ensured by the independence of the commission and its members as well as the determination of facts and their assessment. Criteria are professional standards and required care. Since 1995, 21 requests by affected patients have been reviewed. In 15 cases (71.4%), treatment errors were ascertained. This involved either a delayed or an insufficient diagnosis (prostatic biopsy). In ten of the patients, a mostly early prostate cancer would have be diagnosed and treated at the time of the first finding of PSA values between 3.3 and 10.4 ng/ml. In ten of 13 patients, the tumor was diagnosed late, having PSA values between 6.8 and 1251 ng/ml with no chance of curative therapy. As in other life threatening diseases, time of recognition is most important for the diagnosis and treatment of patients with prostate cancer. Particularly for early recognition, PSA is much more sensitive then digital rectal examination, and in cases without a digital finding is the only parameter for early diagnoses. In men with suspicious PSA values (>4.0 ng/ml) suitable a diagnostic test (prostate biopsy) is required early, until cancer is detected or excluded.

Six-year prospective audit of chest reopening after cardiac arrest

OBJECTIVE

To identify which patients benefit from chest reopening after cardiac arrest.

SETTING

Cardio-thoracic hospital undertaking full range of adult cardio-thoracic surgery.

METHODS

In-hospital arrests were prospectively audited over a 6-year period. Information was collected for every patient whose chest was reopened following cardiac arrest: location of arrest, type of arrest, specialty, time since surgery, time to chest reopening, location of chest opening, surgical findings on reopening, time to cardiopulmonary bypass (if used) and patient outcomes.

EXCLUSIONS

Arrests in theatre and chest openings for reasons other than cardiac arrest.

RESULTS

There were 818 confirmed in-hospital arrests following 'cardiac arrest calls'. Chest reopening was undertaken in 79 surgical patients. Overall survival to discharge was 20/79 (25%). Favourable determinants of outcome were: arrest on intensive care unit (ICU), arrest within 24 h of surgery and reopening within 10 min of arrest. Nineteen of 58 (33%) chest openings following arrests on the ICU survived to discharge compared to one of 21 (5%) patients whose initial arrest was outside the ICU (P=0.017). One of nine ward arrests scooped to ICU for chest reopening survived whereas all 12 patients reopened on the ward died. Fifteen of 40 patients (38%) reopened within 24 h surgery survived compared to five of 39 patients where reopening was undertaken more than 24 h after surgery (P=0.02). Fourteen of 29 (48%) patients opened within 10 min of arrest survived to discharge compared to six of 50 (12%) patients where time to reopening was more than 10 min (P=<0.001). Seven of 22 patients (32%) patients where emergency bypass was utilised survived to discharge.

CONCLUSION

This study strongly confirms the benefit of chest reopening after cardiac arrest in the cardiac surgical ICU. Patients who arrest within 24 h of surgery and in whom reopening is instituted within 10 min are particularly likely to benefit. The value of chest reopening in arrests outside the ICU remains unresolved. All patients reopened on the ward died, suggesting that this practice should be discontinued. Early 'scoop and run' resulted in one solitary survivor though it should probably be restricted to patients who arrest within 72 h of surgery as surgically remediable problems are unlikely after this time.

The involvement, understanding and attitudes of dietitians towards research and audit

AIM

To investigate the involvement of dietitians in research and audit and to assess their understanding of and attitudes towards these activities.

METHODS

A postal questionnaire was used to investigate the knowledge, attitude towards and involvement in research and audit of State Registered Dietitians practising in the National Health Service (NHS) in the UK.

RESULTS

A response rate of 64% was achieved. Few respondents (15%) were currently involved in research, although more (65%) were currently involved in audit. Involvement in audit rose significantly with increasing grade and managerial responsibility. Dietitians qualifying more recently were more likely to believe that their college training prepared them to undertake research, but felt less confident about undertaking audit. Experience of audit made respondents more confident about auditing their work and improved their belief that they understood audit terminology. Higher grade dietitians were more likely to see audit as an important part of their role than were their more junior colleagues. Understanding of the terms 'research' and 'audit' was poor, although 48% of respondents identified the link between the two activities. Perceived constraints to involvement in research and audit were identified.

CONCLUSION

The present level of involvement of dietitians in research and audit activities falls below that recommended in the BDA's (1997a) National Professional Standards for Dietitians Practising in Healthcare. This study identifies factors that influence dietitians' involvement in, understanding of and attitudes towards research and audit and recommends ways of increasing their involvement in these activities.

An audit of fresh frozen plasma usage in a tertiary referral centre in a developing country

This paper evaluates the practice of fresh frozen plasma (FFP) transfusion at the University Hospital, Kuala Lumpur, and analyses its usage by the various clinical departments. The aim of this study is to identify where it is inappropriately used and the clinical indications in which such misuse is common. A retrospective analysis of the blood bank request forms and work sheets during a 6-month period between January 1998 and June 1998 formed the basis of this study. Overall, 40% of 2665 units transfused were considered appropriate. However, out of the 931 episodes of FFP transfusions only 31% were for appropriate indications. The average FFP requirement when used for appropriate indication was about 4 units per episode, whereas for inappropriate indication it was 2.5 units per episode. Inappropriate use in terms of the number of units was highest by the surgical services (68%) and Orthopaedics (64%), while the Department of Paediatrics had the lowest incidence of inappropriate use (40%). When Paediatrics was used as the benchmark, the incidence of inappropriate use by other departments was significantly higher (p < 0.01). As for FFP usage in common clinical indications, there was a high incidence of inappropriate use in burns (82%), perioperative period (73%), cardiac surgery (68%), massive bleeding (62%) and trauma (60%). The findings in this study, specifically the use of FFP for volume support in trauma, massive bleeding and burns, routine requests without identified indication in cardiac bypass surgery, and prophylactic use in the perioperative period can be the basis for recommendations to minimize the inappropriate use of FFP in the future.

Quality measures of antimicrobial drug use

Antimicrobial use is the major determinant in the development of resistance. Many parameters of importance for optimal quality of antimicrobial therapy have already been defined. Maximal efficacy of the treatment should be combined with minimal toxicity at the lowest cost. Quality of antimicrobial drug use is dependent on knowledge of many aspects of infectious diseases. Considering efficacy, many of our indications for antimicrobial use need critical evaluation. Irrational use should be discouraged. Avoidance of the development of resistance is a quality parameter that will need increasing attention. This paper reviews the well-established factors that may influence the appropriateness of pharmacotherapy with antimicrobial drugs. It cites recent evidence supporting principles of prudent prescribing and gives an overview of audits that have addressed these parameters. Measures relating to resistance are discussed.

The problem-based medical audit program: influence on family practice residents' knowledge and skills

BACKGROUND AND OBJECTIVES

Family physicians need to possess the skills to conduct audits in their own clinical settings to ensure that their patients receive exemplary clinical care. Residency offers an important opportunity for physicians to develop these auditing skills. This study describes the introduction of a problem-based medical audit program at three teaching units in the Department of Family Medicine at McMaster University and the program's effect on learner knowledge, skills, and attitudes toward the practice audit.

METHODS

A survey designed to assess residents' self-rated knowledge, skills, and attitudes toward practice audits was distributed before and after residents participated in the audit program.

RESULTS

Forty-three residents were surveyed; 33 (76.7%) completed the initial questionnaire and follow-up questionnaire. Residents reported significant improvements in their understanding of the relevance of audits, ability to develop a practice audit question, skills in designing methodology, and skills needed to conduct an audit independently. Residents also reported a moderate increase in their knowledge of statistics needed to complete an audit.

CONCLUSIONS

The practice audit program at McMaster University uses a problem-based model to introduce learners to the concept of the clinical audit. The practice audit program successfully improved the residents' self-reported ability to conduct an audit and heightened their understanding of the importance and relevance of the audit process.

Assessment of Guillain-Barré syndrome mortality and morbidity in the United States: implications for acute flaccid paralysis surveillance

To estimate age-specific incidences and assess the national morbidity and mortality burden for Guillain-Barre syndrome (GBS) in the United States, a national hospital discharge database compiled by the Commission on Professional and Hospital Activities (CPHA) and national death certificate data reported to the National Vital Statistics System were reviewed. During 1985-1991, 10,453 patients with GBS were discharged from CPHA-participating hospitals (estimated annual incidence, 3.0/100,000 population). The age-specific incidence of GBS increased with age from 1.5/100,000 in persons <15 years old to 8.6/100,000 in persons 70-79 years old. The total estimated number of GBS-related deaths from 1985 through 1990 was 3770 (95% confidence interval, 3506-4034), for an average of 628 GBS deaths per year. These rates suggest that the proposed national surveillance system for acute flaccid paralysis should capture at a minimum the 796 GBS cases in persons <15 years old. GBS remains a significant health burden among older adults in the United States, with a marked increase in risk after age 40.

Utilization of hospital services by the elderly: geriatric crisis in one Canadian single payer system

As the number and proportion of elderly persons in the Canadian population increase, utilization of health services by the elderly becomes a growing concern for health service insurers, financial managers and policy makers, as well as for care providers. The purpose of this paper is to present the results of a study to analyse the use of hospital services by the elderly in Alberta since the introduction of a universal single payer health care insurance system in 1970. The study period coincides with the implementation of publicly-financed comprehensive medical and hospital insurance programmes for all Alberta residents, making it possible to perform historical and population-based utilization analyses. Thus the data used for the study included all hospital discharge abstracts generated by all Alberta hospitals from 1971 to 1991. Trends in hospital service utilization by the elderly in terms of total number of separations, patient-days, and per case measures such as average length of stay as well as per capita utilization rates were reviewed to identify utilization patterns over the study period. Further, relative per capita utilization measures, in comparison with the base year (1971), age group 15-44, male, metropolitan residents, were derived and historical trends identified. A series of regression analyses were carried out to estimate the effects of age, sex and origin on utilization rates. In addition, for the period of 1984-1991, Diagnosis Related Groups (DRG) case weights were used to measure per capita and per case rates and to analyse historical relative utilization rates over the 8-year period. In general, there has been a significant decline in hospital utilization by Albertans under the publicly-financed single payer system, but utilization rates for elderly have remained high, resulting in high relative utilization rates in comparison with other age groups. It was also noted that per capita utilization rates for rural residents were substantially higher than urban residents. It appears that these higher utilization rates by the elderly and rural residents in combination with tight bed and financial control by the government have been causing significant bed shortage problems for non-elderly elective patients in urban areas.
