Adoption of Routine Ultrasound Guidance for Femoral Arterial Access for Cardiac Catheterization

BACKGROUND

A randomized controlled trial published in 2010 demonstrated that ultrasound-guided femoral artery access for coronary angiography was faster and associated with fewer vascular complications than conventional fluoroscopic-guided access. The landscape of ultrasound use among contemporary interventional cardiologists is unknown.

METHODS

We sought to describe current knowledge, attitudes, and practices regarding ultrasound use among interventional cardiologists using an online survey. The questionnaire unfolded in phases, initially attempting to define current attitudes and then testing whether or not attitudes were adjustable after summarizing compelling research supporting the use of ultrasound-guided access.

RESULTS

Sixty-eight responses were received (60.7%). Only 13.3% reported using ultrasound routinely despite widespread availability and technical expertise. The majority of respondents believed ultrasound use to be slower but safer than access by palpation alone. There was no significant association between age (P=.70) or annual case volume (P=.11) and baseline ultrasound use. After examining the results of a supporting clinical trial, 42.6% said ultrasound should be used routinely, but only 17.6% said they would adopt the technique. Younger operators tended to affirm routine ultrasound adoption after reading the trial summary more often than older respondents, although this did not reach statistical significance (relative risk = 1.8; P=.30).

CONCLUSIONS

Routine ultrasound-guided femoral artery access and awareness of its validating evidence is uncommon among current interventional cardiologists; exposure to compelling data had minimal impact on respondents' willingness to change practice.

Detection of Postoperative Surgical-Site Infections: Comparison of Health Plan–Based Surveillance With Hospital-Based Programs

Background:

Review of health plan administrative data has been shown to be more sensitive than other methods for identifying postdischarge surgical-site infections (SSIs), but there has not been a direct comparison between this method and hospital-based surveillance for all infections, including those diagnosed before discharge. We compared these two methods for identifying SSIs following coronary artery bypass graft (CABG) procedures:.

Methods:

We studied 1,352 CABG procedures performed among members of one health plan from March 1993 through June 1997. Health plan administrative records were reviewed based on claims containing diagnoses or procedures suggestive of infection or outpatient dispensing of antibiotics appropriate for SSI. Hospital-based surveillance information was also reviewed. SSI rates were calculated based on the total events identified by either mechanism.

Results:

Postdischarge information was reviewed for 328 (85%) of 388 procedures. SSIs were confirmed in 167 patients (13% overall risk of confirmed SSI; range, 3% to 14% in the 5 hospitals). The overall sensitivity of hospital-based surveillance was 49.7% (83 of 167), and that of health plan data was 71.8% (120 of 167). There was no significant difference among hospitals in the sensitivity of either surveillance mechanism.

Conclusions:

Surveillance based on health plan data identified more postoperative infections, including those occurring before discharge, than did hospital-based surveillance. Screening administrative data and pharmacy activity may be an important adjunct to SSI surveillance, allowing efficient comparison of hospital-specific rates. Interpretation of differences among hospitals' infection rates requires case mix adjustment and understanding of variations in hospitals' discharge diagnosis coding practices

Who needs a palliative care consult?: the Hamilton Chart Audit tool

Although palliative care services are becoming increasingly prevalent in acute care hospitals only a minority of patients who die in hospital or in the community have seen palliative care teams. There are large numbers of patients who might benefit from palliative care who are not receiving it. That said, identification of patients who are eligible for these services, and of those who would most benefit is problematic. Limitations in our ability to accurately predict prognosis as well as lack of universal agreement as to what constitutes a terminal illness, or "end of life" are important considerations. Another significant challenge faced by our health care systems is whether or not all "end-of-life" patients require specialized care by trained palliative care providers. Even if this were the ideal model of care, this would be unfeasible given the relatively small number of trained providers compared to the aging and dying population. Therefore it is critical that health care systems begin to standardize their approach to the identification of patients who are most in need of, and/or most likely to benefit from interventions by interdisciplinary palliative care teams. Institutions that are planning to develop new services, or expand their current services will require some method/tool to assess specific population needs at their site. The Hamilton Chart Audit (H-CAT) was developed at our institution to help identify potential palliative care needs of patients and their families. We report on development of the tool and use of the tool for a retrospective audit of 222 patients who died at our institution.

Managing the interface between acute care and rehabilitation - can utilisation review assist?

AIMS AND METHODS

We piloted the InterQual Criteria tool in a large regional acute hospital in NSW to determine the utility of this tool in the Australian context. In particular to compare the current "gold standard" of physician assessment for the selection of patients for rehabilitation and the timing of transfer, with the guidance provided by the tool. Consecutive acute care patients with a diagnosis of stroke, hip fracture or amputation, and patients referred for rehabilitation assessment, were followed using the InterQual Criteria.

RESULTS

Results on 242 acute episodes, representing 2698 days in acute care, were analysed. In accordance with overseas studies, we found that high levels of inappropriate days of stay in acute care were suggested by the tool. Using the InterQual Criteria almost all patients were deemed appropriate for transfer to rehabilitation much earlier than current practice.

CONCLUSION

We conclude that the InterQual Criteria may have a useful role in patient selection for rehabilitation, in facilitating the transfer of patients from acute to subacute care, and in improving patient flow within acute care. The reasons for the variation between the results obtained from the tool and current clinical practice requires further investigation, and may indicate a lack of validity of the tool in the Australian setting, inefficiencies in processes of acute care, or the lack of suitable alternative care settings or level of support available in these settings.

Concurrent projects aim to improve satisfaction

A concerted effort involving several initiatives can make a big difference in your patient satisfaction scores. The ED at Williamsport (PA) Hospital increased their rates from a low of 65.6% to more than 83% in less than 18 months using strategies that included: The addition of patient service representatives to help make patients more comfortable and keep them apprised of waiting time expectations. A switch in primary staffing of the 'Urgicenter' from physicians to physician assistants. A new triage process that gets patients back into the ED proper much more quickly.

Best practices for improving revenue capture through documentation

Tips for engaging physicians in efforts to enhance clinical documentation include: Individual physician profiling; Physician education, ranging from simple poster campaigns to hiring a full-time DRG education employee; Timely reinforcement support; Training internal employees to act as "documentation specialists"; Simplifying forms used for coding.

Is managed care closing substance abuse treatment units?

Despite high levels of unmet need for outpatient substance abuse treatment, a significant percentage of outpatient units have closed over the past several years. This study drew on 1999-2000 and 2005 national surveys to determine if managed care was associated with outpatient substance abuse treatment units' likelihood of surviving. Each substance abuse unit director was asked about the presence of any managed care contracts, percentage revenues from managed care, percentage of clients for whom prior authorization was required, and percentage of clients for whom concurrent review was required. A multiple logistic regression revealed that none of these factors was associated with substance abuse treatment unit survival. At this point, neither the presence nor the structure of managed care appears to affect the survival of outpatient substance abuse treatment units. Given the need for these facilities, however, and their vulnerability to closure, continued attention to managed care's potential influence is warranted.

Effect of drug utilization reviews on the quality of in-hospital prescribing: a quasi-experimental study

Background

Drug utilization review (DUR) programs are being conducted in Canadian hospitals with the aim of improving the appropriateness of prescriptions. However, there is little evidence of their effectiveness. The objective of this study was to assess the impact of both a retrospective and a concurrent DUR programs on the quality of in-hospital prescribing.

Methods

We conducted an interrupted time series quasi-experimental study. Using explicit criteria for quality of prescribing, the natural history of cisapride prescription was established retrospectively in three university-affiliated hospitals. A retrospective DUR was implemented in one of the hospitals, a concurrent DUR in another, whereas the third hospital served as a control. An archivist abstracted records of all patients who were prescribed cisapride during the observation period. The effect of DURs relative to the control hospital was determined by comparing estimated regression coefficients from the time series models and by testing the statistical significance using a 2-tailed Student's t test.

Results

The concurrent DUR program significantly improved the appropriateness of prescriptions for the indication for use whereas the retrospective DUR brought about no significant effect on the quality of prescribing.

Conclusion

Results suggest a retrospective DUR approach may not be sufficient to improve the quality of prescribing. However, a concurrent DUR strategy, with direct feedback to prescribers seems effective and should be tested in other settings with other drugs.

Uso inadecuado de la hospitalización en cirugía general. Magnitud, factores asociados y causas

OBJECTIVE

To determine the proportion of inappropriate days of hospitalization in the general surgery wards of three university hospitals, its causes, and associated factors.

MATERIAL AND METHOD

We concurrently reviewed 596 days of hospitalisation during a 1-week period in 2000, using the Appropriateness Evaluation Protocol (AEP). The association among inappropriate days of hospital stay and independent variables was evaluated using bivariable and multivariable methods. Finally, the causes for inappropriate hospitalization use were analyzed.

RESULTS

The percentage of inappropriate days was 17.6%, with no significant differences among the hospitals (21.5%, 12.5% and 17.5%). Inappropriate days were associated with the weekend (odds ratio [OR] = 2.1, scheduled admissions (OR = 2.9), hospital stay of more than 1 week (OR:2.3), the last third of the hospital stay (OR: 3.7), and inappropriate admission (OR: 2.1). The main causes of inappropriate hospital stays were organizational problems in the hospital or in the clinical management of discharge.

CONCLUSIONS

Inappropriate days of hospitalization represent a considerable percentage of hospitalization in surgery wards. The main reasons for inappropriate days are problems with surgical and discharge planning and factors that depend on the organization of the surgery departments and other related departments in the hospital.

Education earns high comparative AMI rankings

Initiatives enable facility to gain high rankings in five clinical measures. Even though physicians know what they should do, reminders still are necessary. Physicians who are not compliant with new pathways are talked to by department chairs.

Improving Patient Outcomes in an Ambulatory Infusion Setting

Nurses working in the outpatient ambulatory setting treat patients with multiple infusion drug regimens. Patients can have allergic reactions to infusions ranging from very mild to life-threatening. The reaction and the subsequent treatment measures can be very disconcerting to the patients and to the visitors in the infusion area. The nursing team described in this article took a proactive approach to minimize infusion reactions in the authors' facility, thereby ensuring the safety of other patients. Staff members examined the performance improvement data, conducted a retrospective study, and collaborated with the primary physician providers to develop rechallenge protocols for patients receiving paclitaxel and carboplatin regimens.

Factors causing patients to delay seeking treatment after suffering a stroke

Many studies have looked at issues surrounding why people delay in accessing healthcare after they have experienced a stroke, but no published studies on this subject have been conducted in West Virginia. To identify the factors causing patients to delay treatment for a stroke, we conducted a concurrent chart review of 64 acute stroke and TIA patients presenting at Charleston Area Medical Center from April 1, 2003 to July 21, 2003. Results showed that the majority of patients arrived beyond the critical three-hour limit for tissue plasminogen activator (tPA) medication. The patients who reported speech problems and confusion as their initial symptoms, those who lived within 15 miles of the hospital, and those who used ambulance transport, were most likely to arrive at the hospital in less than two hours. On the other hand, the patients who were less likely to arrive within two hours were those who were alone at symptom onset, those who had weakness as a prominent symptom, as well as those were younger and had commercial insurance. We recommend educating the community about the symptoms of stroke and focusing on the fact that stroke is a medical emergency and calling 911 is necessary.

A proactive (and financially beneficial!) approach to utilization management

Today's environment offers a host of utilization management challenges for healthcare providers. If hospitals are to minimize denials and reduce costs amid these pressures, they will need to adopt several key strategies, including effectively employing use of a dedicated physician adviser.

Spironolactone use in patients with heart failure

BACKGROUND

The addition of spironolactone, an aldosterone antagonist, to standard therapy can reduce the risk of both morbidity and mortality in patients with severe heart failure.

OBJECTIVE

To evaluate the use of spironolactone in class III and IV heart failure patients in four urban teaching hospitals.

METHODS

We conducted a concurrent medical record review of 163 patients with documented heart failure admitted to a general medicine service over a 5-week period. Data retrieved included patient demographics, heart failure class, left ventricular ejection fraction, spironolactone contraindications, spironolactone use, dose and frequency, and other heart failure medication use, dose and frequency. All data reflected patients' baseline status.

RESULTS

Our patient population was 80% white people, 61% male, with a mean age of 70 years (35-99). A total of 114 had class III or IV heart failure (70%). Angiotensin-converting enzyme inhibitors or appropriate alternative were prescribed in 117 (72%) patients, whereas beta-blockers were used in 121 (74%) patients. Fifty-seven patients met spironolactone ideal candidate criteria. Of these, eight (14%) were appropriately prescribed spironolactone.

CONCLUSIONS

Three years after publication of the Randomized Aldactone Evaluation Study, spironolactone is underutilized in the treatment of heart failure. Results of this study indicated that the majority of patients in class III or IV heart failure were not prescribed spironolactone. Improvements in spironolactone prescribing are needed.

Clinical Risk Groups (CRGs)

OBJECTIVE

To develop Clinical Risk Groups (CRGs), a claims-based classification system for risk adjustment that assigns each individual to a single mutually exclusive risk group based on historical clinical and demographic characteristics to predict future use of healthcare resources. STUDY DESIGN/DATA SOURCES: We developed CRGs through a highly iterative process of extensive clinical hypothesis generation followed by evaluation and verification with computerized claims-based databases containing inpatient and ambulatory information from 3 sources: a 5% sample of Medicare enrollees for years 1991-1994, a privately insured population enrolled during the same time period, and a Medicaid population with 2 years of data.

RESULTS

We created a system of 269 hierarchically ranked, mutually exclusive base-risk groups (Base CRGs) based on the presence of chronic diseases and combinations of chronic diseases. We subdivided Base CRGs by levels of severity of illness to yield a total of 1075 groups. We evaluated the predictive performance of the full CRG model with R2 calculations and obtained values of 11.88 for a Medicare validation data set without adjusting predicted payments for persons who died in the prediction year, and 10.88 with a death adjustment. A concurrent analysis, using diagnostic information from the same year as expenditures, yielded an R2 of 42.75 for 1994.

CONCLUSION

CRGs performance is comparable to other risk adjustment systems. CRGs have the potential to provide risk adjustment for capitated payment systems and management systems that support care pathways and case management.

The impact of verbal communication on physician prescribing patterns in hospitalized patients with diabetes

PURPOSE

The purpose of this descriptive clinical research study was to identify which method of communication, verbal or written, has the greatest impact on physician adjustment of the antidiabetes medication regimen for hospitalized patients with hyperglycemia.

METHODS

The medical records for 1026 patients hospitalized with diabetes at a large, metropolitan, not-for-profit teaching hospital were reviewed by the diabetes inpatient clinicians to identify hyperglycemia and the potential need to initiate or adjust the antidiabetes medication regimen. The study evaluated the effectiveness of verbal versus written communication between the diabetes inpatient clinician and the physician regarding cases where the current antidiabetes medication regimen was not optimal.

RESULTS

Verbal interaction between the diabetes inpatient clinician and the physician resulted in a greater number of changes in the antidiabetes medication regimen.

CONCLUSIONS

Communication modality correlates with changes in antidiabetes medications prescribed by physicians and may be an effective tool to facilitate inpatient glycemic control.

How to minimize inappropriate utilization of Accident and Emergency Departments: improve the validity of classifying the general practice cases amongst the A&E attendees

Studies have found that one-third to two-thirds of all patients attending Accident and Emergency (A and E) Departments could be managed appropriately by general practitioners (GPs). There is also evidence that referral to GPs can be acceptable to patients. The question of primary concern is screening non-urgent cases with high degrees of sensitivity (S), specificity (SP), and positive predictive value (PPV). This paper reports the findings of the validity (S, SP and PPV) of nurses and patients in triaging A and E visitors. A cross sectional study was conducted over a 1 year period and subjects were randomly selected from four A and E Departments located across the four principle geographic regions of Hong Kong by stratified, two-stage sampling. S, SP and PPVs were computed for both non-weighted and weighted conditions. The gold standard for defining the true urgency status of each selected patient was based on a review of the patient's record 3-21 days (or longer if necessary) following the A and E visit. The record review in each A and E was blinded and done independently by a panel of two (and if disagreement existed, three) senior emergency physicians who did not practice in the same hospital. The greatest weights would be for incorrect decisions with greatest impact on patients' well being. The most accurate unweighted nurses' triage classification had an average sensitivity of 87.8%, specificity of 83.9%, and a PPV of 70.1%. When weighted, the average sensitivity reduced to 75%, specificity to 65.7%, and PPV to 54%. The most accurate unweighted patients' self-triage classification yielded a sensitivity of 62.5%, specificity of 69.2%, and a PPV of 58.1%, and correspondingly reduced to 43.3, 49.2 and 38.6% if weights were applied. Validity of the derived patients' self-classifications was too inaccurate for practical use. Hong Kong's current use of a five-point urgency scale by nurses would be further refined for identifying non-urgent visitors. If a mechanism was put in place for additional screening on visitors with a borderline semi-urgent or non-urgent status, the nurses could safely reassign non-urgent patients to GP care. If implemented, a significant impact on hospital costs could be realized.

Denials of reimbursement for hospital care

Much of the negative perception of managed care focuses on fear of denials of certification for reimbursement. This study examined more than 50,000 concurrent utilization reviews completed over a four-year period (1998-2001) at a large teaching hospital. The results showed a denial rate of less than 1.5% of all patients reviewed, higher denial rates among certain clinical services, higher rates of reviews among certain services only partially explained by volume of admissions, and a lack of patient criteria to receive care in the inpatient setting as the most frequent reason given for denial.

Validation of the Hendrich II Fall Risk Model: a large concurrent case/control study of hospitalized patients

This large case/control study of fall and non-fall patients, in an acute care tertiary facility, was designed to concurrently test the Hendrich Fall Risk Model. Cases and controls (355/780) were randomly enrolled and assessed for more than 600 risk factors (intrinsic/extrinsic). Standardized instruments were used for key physical attributes as well as clinician assessments. A risk factor model was developed through stepwise logistic regression. Two-way interactions among the risk factors were tested for significance. The best fitting model included 2 Log L chi square statistic as well as sensitivity and specificity values retrospectively. The result of the study is an easy to use validated Hendrich Fall Risk Model with eight assessment parameters for high-risk fall identification tested in acute care environments.

Profiling resource use: do different outcomes affect assessments of provider efficiency?

OBJECTIVES

To examine whether 2 outcome measures result in different assessments of efficiency across 22 service networks within the Department of Veterans Affairs (VA).

STUDY DESIGN

A retrospective analysis using VA inpatient and outpatient administrative databases.

METHODS

A 60% random sample of veterans who used healthcare services during fiscal year 1997 was split into a 40% sample (n = 1,046,803) for development and a 20% sample (n = 524,461) for validation. Weighted concurrent case-mix models using adjusted clinical groups were developed to explain variation in 2 outcomes: "days of care"--the sum of a patient's inpatient and outpatient annual visit days, and "average accounting costs"--the sum of the average service costs multiplied by the units of service for each patient. Two profiling indicators were calculated for each outcome: an unadjusted efficiency index and an adjusted efficiency index. These indices were compared to examine network efficiency.

RESULTS

Although about half the networks were identified as "efficient" before and after case-mix adjustment, assessments of individual network efficiency were affected by the adjustment. The 2 outcomes differed on which networks were efficient. For example, 4 networks that appeared as efficient based on days of care appeared as inefficient based on average costs.

CONCLUSIONS

Assessments of provider efficiency across the 22 networks depended on the outcome measure used. Knowledge about the extent to which assessments of provider efficiency depend on the outcome measure used is an important step toward improved and more equitable comparisons across providers.

Reducing failed extubations in the intensive care unit

BACKGROUND

Failed extubation is associated with substantially increased morbidity, mortality, and costs for patients receiving mechanical ventilation. A study was designed in 1998 to identify risk factors for failed extubation and use a quality improvement model to reduce failed extubation rates in a surgical intensive care unit (SICU) in an academic hospital.

METHODS

Study design involved a prospective cohort SICU with a concurrent control SICU. The primary outcome was rate of failed extubations per 1,000 ventilator days. Information on risk factors for failed extubations was also collected. Performance improvement staff identified failed extubation patients, and respiratory therapy provided information on ventilator days. The quality improvement model implemented three phases between October 1998 and June 2000: (1) identifying factors associated with failed extubation, (2) developing a guideline to reduce failed extubation, and (3) implementing the guideline.

RESULTS

Significant factors associated with failed extubation included suctioning more frequently than every 4 hours versus the current model of "every 4 hours or greater" (odds ratio [OR] 11.3; 95% confidence interval [CI] 1.5-88.3), being agitated or sedated versus being alert (OR 4.5, CI: 1.2-14.7), and oxygen saturation < or = 95% versus > or = 95% (OR 4.0; CI: 1.2-13). Failed extubation rate in the SICU decreased from 8/1,000 in October 1998 to 1.5/1,000 in June 2000, and control SICU rates remained unchanged (8/1,000).

DISCUSSION

The intervention significantly reduced the rate of failed extubation in the SICU. By employing a quality improvement model and identifying risk factors for failed extubation, providers should be able to decrease risk of failed extubation for SICU patients.

A nurse practitioner intervention model to maximize efficient use of telemetry resources

BACKGROUND

Telemetry monitoring is widely used in hospitals; the importance of being able to monitor and examine dysrhythmias has been universally accepted. Yet it is often used for patients who do not actually require this technology. A model to improve the efficiency of telemetry use entailed the use of an advanced practice nurse (APN; identical to a nurse practitioner) to provide concurrent review and intervention of floating telemetry, which is available for patients independently of the floor location and who do not need an intensive care unit bed. ADDRESSING OVERUSE: The demand for floating telemetry at Hackensack University Medical Center had equaled or exceeded the telemetry availability virtually 100% of the time, even after local guidelines had been disseminated in 1998. The APN carried out concurrent monitoring and intervened with the attending physician when patients were on telemetry for longer than 48 hours and did not meet the local telemetry guidelines.

RESULTS

The mean number (standard error [SE]) of hours per patient declined from 65.2 +/- 0.7 hours (95% confidence interval, 63.8 to 66.6 hours) for the 11 months before the intervention to a mean of 49.6 +/- 0.4 hours (95% confidence interval, 48.7 to 50.2 hours) for the 29 months after intervention--representing a decrease of 34% (p < 0.0001). This decrease led to an increase in the number of patients per month put on telemetry.

DISCUSSION

The APN model, an aggressive approach that induced change almost immediately, was then applied to other quality improvement projects.

Methodology to improve data quality from chart review in the managed care setting

BACKGROUND

Because inherent variability may exist in data collected by multiple reviewers or from potential difficulties with data abstraction tools, we developed a standardized method of evaluating interrater reliability (IRR) for clinical studies, HEDIS effectiveness of care measures, and onsite/medical record reviews.

OBJECTIVE

To demonstrate the ability of our standardized methods of data collection and analysis of results to determine the extent of agreement between multiple reviewers; identify areas for improvement in data collection procedures; and improve data reliability.

STUDY DESIGN

A prospective chart review with concurrent IRR.

METHODS

A subsample of patient records included in the Highmark Blue Cross Blue Shield/Keystone Health Plan West basic medical review for each HEDIS measure was selected for the IRR study. An experienced nurse ("gold standard") conducted a blinded concurrent review of these records. Using the kappa statistic (kappa) we evaluated interobserver agreement between results of the onsite reviewers and the "gold standard" from 1997 through 2000. Revised data collection methods and enhanced reviewer training were incorporated for measures showing areas for rater improvement.

RESULTS

Results across years showed excellent IRR for most measures; however, each year 1 or 2 measures showed areas for rater improvement (1997 Papanicolaou kappa = 0.50; 1998 well-child visits 3 to 6 years kappa = 0.37; 1999 comprehensive diabetes kappa = 0.73; high blood pressure kappa = 0.73). After reevaluating these measures, the results of the kappa showed excellent interrater agreement in subsequent years.

CONCLUSIONS

Standardized methods of data collection and evaluation of IRR results provides health plans increased confidence in data collection, statistical analyses, and in reaching conclusions and deriving relevant recommendations.

Diagnostic cost groups (DCGs) and concurrent utilization among patients with substance abuse disorders

OBJECTIVE

To assess the performance of Diagnostic Cost Groups (DCGs) in explaining variation in concurrent utilization for a defined subgroup, patients with substance abuse (SA) disorders, within the Department of Veterans Affairs (VA).

DATA SOURCES

A 60 percent random sample of veterans who used health care services during Fiscal Year (FY) 1997 was obtained from VA administrative databases. Patients with SA disorders (13.3 percent) were identified from primary and secondary ICD-9-CM diagnosis codes.

STUDY DESIGN

Concurrent risk adjustment models were fitted and tested using the DCG/HCC model. Three outcome measures were defined: (1) "service days" (the sum of a patient's inpatient and outpatient visit days), (2) mental health/substance abuse (MH/SA) service days, and (3) ambulatory provider encounters. To improve model performance, we ran three DCG/HCC models with additional indicators for patients with SA disorders.

DATA COLLECTION

To create a single file of veterans who used health care services in FY 1997, we merged records from all VA inpatient and outpatient files.

PRINCIPAL FINDINGS

Adding indicators for patients with mild/moderate SA disorders did not appreciably improve the R-squares for any of the outcome measures. When indicators were added for patients with severe SA who were in the most costly category, the explanatory ability of the models was modestly improved for all three outcomes.

CONCLUSIONS

Modifying the DCG/HCC model with additional markers for SA modestly improved homogeneity and model prediction. Because considerable variation still remained after modeling, we conclude that health care systems should evaluate "off-the-shelf" risk adjustment systems before applying them to their own populations.

Prenatal HIV counseling and testing in California: women's experiences and providers' practices

Two concurrent surveys were conducted in four California counties to compare the prenatal HIV counseling and voluntary testing (C&VT) experiences of women with the self-reported practices of prenatal care providers. Participants were 850 women currently or recently receiving prenatal care and 254 providers. Although 79.9% of women reported being offered an HIV test during a prenatal visit, only 56.2% said they were told about the risks and benefits of taking an HIV test. Almost all providers (98.4%) indicated they offer an HIV test, and 76.8% reported offering counseling, to every patient. One third of the women (65.9%) knew that treatment exists for reducing the chance of prenatal transmission of HIV, and 78.7% of women said they were more likely to be tested given knowledge of such therapy. Women may have underreported prenatal C&VT because providers spend insufficient time discussing related issues or because C&VT information is not presented in a way that is relevant to all patients.

Use of measurement audit in outcomes management

With the growing emphasis on accountability in mental health services, outcomes management strategies are gaining popularity. However, for these techniques to be credible, it is necessary to ensure the reliability of clinical data. In other words, outcomes measures must accurately reflect the actual status of service recipients. This article presents the use of the measurement audit as one means of monitoring and improving the reliability of outcomes measurements. The methods and findings from an audit of crisis assessment workers for children in state custody are presented. Clinical assessments completed at the time of service were compared with assessments using the same measure completed via retrospective file review. Findings suggest generally good reliability, 0.72 overall, with some variation by provider and type of information.

Next phase of medical management systems: automating administrative transactions to integrate payors and providers

Today, medical management is burdened by the cost and hassle of manual administrative tasks. Manual intensive processing (that is, phone and fax) of referral requests and institutional authorization transactions results in significant unnecessary costs for the providers and payors, delays in approval, and problems with errors. To address these administrative burdens, the next phase of online (Internet- and wireless-enabled) medical management applications will focus on the administrative and transaction side, including self-service referral and authorization processing between the payor and provider. The advent of the Health Insurance Portability and Accountability Act (HIPAA) greatly improves the ability to gain widespread adoption of these online applications thanks to mandated standardization of many routine transactions. This article explores this next phase of online administrative and transaction medical management applications from the payors' perspective and explores their connectivity with providers. Payors are striving to meet several objectives as they implement these online administrative and transaction medical management systems: reducing the administrative burden and cost, changing traditional medical policies, increasing provider adoption of connective technologies, addressing HIPAA compliance, and achieving higher levels of system integration.

Implementation of standing field treatment protocols in an urban EMS system

The objective was to describe our experience with implementation of standing field treatment protocols (SFTP) in a large, urban EMS system. A prospective, consecutive observational study examining the first 21 days of implementation of SFTPs in the City of Los Angeles, California. SFTPs were developed for 7 medical chief complaints and all major trauma patients. There were 13,586 EMS incidents, of which 4,037 (30%) received ALS treatment. SFTPs were used on 2,177 of these incidents, representing 54% of all ALS runs and 16% of all EMS incidents. The most frequently used SFTPs were for altered level of consciousness (29%), and chest pain (25%). The most common errors found were failure to document reassessment of the patient after each medication administration (45% fallout rate), and failure to document and attach a copy of the ECG to the EMS report (40%). The mean fallout rate for failure to establish or attempt IV access, administer oxygen, or provide cardiac monitoring was 7%. Out of 1,450 incidents with outcome data provided by the receiving hospitals, only 3 cases (2%) involved incorrect treatment, with an additional 2 involving the unnecessary use of lidocaine. None of these instances resulted in adverse effects or complications. SFTPs were integrated into a large EMS system with few procedural errors or adverse outcomes.

Inappropriate use of an accident and emergency department: magnitude, associated factors, and reasons--an approach with explicit criteria

BACKGROUND

We evaluate the appropriateness of medical visits to the accident and emergency department (A&ED) of a university hospital using an instrument based on explicit and objective criteria, analyze the association between inappropriate visits and certain factors, and identify reasons for inappropriate use.

METHODS

This concurrent review of a random sample of 2,980 adult medical patients' visits to the A&ED of the hospital of Elche uses the Hospital Urgencies Appropriateness Protocol, an instrument based on explicit criteria. We analyze the association between inappropriate use and specific factors, and provide a descriptive analysis of reasons for inappropriate use assigned by A&ED staff.

RESULTS

Of the total number, 882 (29.6%) of the visits were evaluated as inappropriate. Inappropriate use was associated with younger patients, use of own means of transportation, referral by the hospital, certain months of the year, and certain diagnostic groups of lesser severity. The most frequent reasons for inappropriate use were the patients' greater trust in the hospital than primary care (451 [51.1%]), inappropriate use of services by patients (160 [18.1%]), and inappropriate referrals by primary care physicians (142 [16.1%]).

CONCLUSION

Inappropriate use represents an important percentage of use of the A&ED. Many reasons contribute to it, although foremost among them is patient preference (and the convenience and accessibility) of these services compared with primary care.

Gatekeepers and sentinels. Their consolidated effects on inpatient medical care

Evaluations assessing precertification by nurse gatekeepers and onsite monitoring by nurse sentinels report inconclusive unique effects of these programs on the utilization, expense, and appropriateness of inpatient medical care. By applying the fixed- and random-effects paradigm of meta-analysis, this article consolidates the results of all relevant quasi-experiments conducted by an evaluation group of a large private insurer from 1986 to 1990. It determines the difference in effect between the target and comparison groups, reports this effect and its statistical range, and determines the pooled effect and its range. The random effects indicate that precertification will reduce admissions, and onsite, concurrent review will reduce length of stay, bed days, and inpatient ancillary expense. The precertification and onsite programs may reduce negative iatrogenic effects, thereby enhancing the patients' well-being. If applied to privately insured populations who are still served on a fee-for-service basis, the gatekeeper and sentinel effects of these programs may reduce utilization and expense; however, inference of these results to Medicare fee-for-service care remains problematical.

Underutilization of acute care settings in a tertiary care hospital

OBJECTIVE

To estimate underutilization of acute care settings in a tertiary care hospital.

DESIGN

A retrospective and concurrent cohort study using chart reviews and the Intensity of service, Severity of illness, Discharge screen for Acute Care (ISD-AC(R)) tool to measure appropriateness of acute care for patients who were receiving care in a less acute setting, as an indicator of underutilization.

SETTING

A 450-bed tertiary care teaching hospital.

STUDY PARTICIPANTS

Patients discharged from the emergency department, patients discharged from acute care inpatient units and patients in acute, non-critical care settings.

INTERVENTIONS

None.

MAIN OUTCOME MEASURES

The percentage of patients discharged from the emergency department who did not meet the criteria for acute care discharge screens; the percentage of patients discharged from an acute care inpatient unit who did not meet the criteria for discharge screens; and the percentage of patients who were in acute, non-critical care beds and who met the criteria for critical care.

RESULTS

It was found that six out of 168 patients [3.57%; 95% confidence interval (CI), 1.32-7.61%] did not meet the discharge screens at the time of discharge from the emergency department. Four out of 156 patients (2.56%; 95% CI, 0.70-6.43%) did not meet the discharge screens at the time of discharge from an acute care inpatient service and two out of 156 acute care patients (1.33%; 95% CI, 0.02-4.73%) who were in non-critical care beds met the criteria for critical care.

CONCLUSION

These findings of underutilization may help to quantitate an unmet need in health care.

Using a continuous time hidden Markov process, with covariates, to model bed occupancy of people aged over 65 years

Previously, the application of a continuous time hidden Markov model with discrete states was used to model geriatric inpatient behaviour. This was itself built on research using a discrete deterministic model to represent the flow of geriatric patients around departments of geriatric medicine. This paper uses the continuous time hidden Markov models and includes the effect of covariates, age and sex, in the model. Fitting the models we can visually see that the two compartment models provides estimates that are much closer to those observed in the data. The addition of covariates provides us with evidence of a difference in length of stay between men and women. However, even significant alterations to the mean age of patients in the model does not effect the length of stay.

The role of brain computed tomography in evaluating children with new onset of seizures in the emergency department

BACKGROUND

The purpose of neuroimaging of a patient with new onset of seizures is to demonstrate cause and explore the prognosis. It was recently recommended that emergency brain computed tomography (CT) be performed only in adult seizure patients with an increased likelihood of life-threatening lesions, i.e., those with new focal deficits, persistent altered mental status, fever, recent trauma, persistent headaches, history of cancer, history of anticoagulation, or suspicion of acquired immunodeficiency syndrome. The objective of this study was to determine the diagnostic utility of emergency brain CT in children who present to the emergency department with new onset of seizures.

METHODS

A 1-year retrospective chart review of all children who presented to the emergency department of the Schneider Children's Hospital with a new onset of seizures and who underwent CT of the brain, excluding children with simple febrile seizures.

RESULTS

Sixty-six patients, 34 boys and 32 girls with a mean age of 4.9 years, qualified for inclusion in the study. Fifty-two patients (78.8%) had normal CT results and 14 patients (21.2%) had abnormal CT results. Seizure cause was considered cryptogenic in 33 patients, of whom 2 (6%) had abnormal CT results; neither patient required intervention. Seizure cause was considered symptomatic in 20 patients, of whom 12 (60%) had abnormal CT results (p < 0.0001). In two patients with abnormal CT scans (both acute symptomatic), the imaging findings were of immediate therapeutic significance and were predictable from the clinical history and the physical examination. None of the 13 patients with complex febrile seizure cause had an abnormal CT scan. Patients with partial convulsive seizures were more likely to have abnormal CT scans than patients with generalized convulsive seizures, but the difference was not statistically significant.

CONCLUSIONS

The routine practice in many pediatric emergency departments of obtaining brain CT scans for all patients with new onset of nonfebrile seizures is unjustified. History and physical examination are sufficient to identify those patients for whom such studies are likely to be appropriate. Emergent CT is not indicated for patients with no known seizure risk factors, normal neurological examinations, no acute symptomatic cause other than fever, and reliable neurological follow-up. For these patients, referral to a pediatric neurologist for further workup, including electroencephalography and the more diagnostically valuable magnetic resonance imaging, would be more appropriate.

Patients' and providers' perceptions of outpatient treatment termination in a managed behavioral health organization

OBJECTIVE

A common complaint about managed care is that treatment decisions of patients and providers are frequently altered by concurrent review of ongoing outpatient treatment. The objective of this study was to examine this perception from the perspectives of patients and providers.

METHODS

A total of 190 patients and their providers were surveyed about the reason that outpatient treatment was terminated. The sample was randomly drawn from completed outpatient treatment episodes of a large national managed behavioral health organization.

RESULTS

In more than three-quarters of the cases, outpatient treatment ended because patients and providers agreed that treatment goals were partially or completely met. Only 5 percent of patients and 3 percent of providers said that treatment ended because the managed care organization denied ongoing treatment. Agreement between patient-provider pairs was generally poor regarding the perceived reason for termination, except when termination was attributed to concurrent review by the managed behavioral health organization.

CONCLUSIONS

In this study of a single large managed behavioral health organization, outpatient treatment was most likely to end based on the decisions of patients and providers rather than utilization review decisions.

The bill drops here. Concurrent coding reduces billing delays, improves accuracy and saves time and money

PROBLEM

Salinas Valley wanted to improve its reporting procedures to payors for reimbursement. Delays in reporting referred outpatients and inpatients can significantly impact receipt of reimbursements from payors.

SOLUTION

Salinas Valley developed a program of concurrent coding in which every procedure is assigned a reimbursement code that is automatically registered in the patient's B/AR record when the procedure is logged into any of the clinical applications in the healthcare information system.

RESULTS

Quicker turnaround on receiving payments from payors, as well as an increased return on investment as the ratio of reimbursement to cost-of-time-spent increases.

KEYS TO SUCCESS

Integral to the success of the concurrent coding review program was the openness of the operating system at Salinas Valley.

Effects of health care cost-containment programs on patterns of care and readmissions among children and adolescents

OBJECTIVES

This study examined the effects of a utilization management program on patterns of medical care among children and adolescents.

METHODS

From 1989 through 1993, the program conducted 8568 reviews of pediatric patients, ranging in age from birth to 18 years. The program used preadmission and concurrent review procedures to review and certify patients' need for care. This study used multivariate analyses to assess changes in the number of days of inpatient care approved by the program and to determine whether limitations imposed on length of stay affected the risk of 60-day readmission.

RESULTS

Concurrent review reduced the number of requested days of inpatient care by 3.2 days per patient. Low-birthweight infants and adolescent patients with depression or alcohol or drug dependence accounted for a disproportionate share of the reduction. Patients classified as admitted for medical or mental health care and whose stay was restricted by concurrent review were more likely (P < .05) to be readmitted within 60 days after discharge.

CONCLUSIONS

By limiting care through its review procedures, the utilization management program decreased inpatient resource consumption but also increased the risk of readmission for some patients. Continued investigation should be conducted of the effects of cost-containment programs on the quality of care given to children and adolescents, especially in the area of mental health.
