Potential access and revealed access to pain management medications.

The area configuration of healthcare resources, such as the number of hospitals per hundred thousand population, has often been used in healthcare planning and policy making to estimate the global access (potential access) of health services to a local population. However, the actual utilization of the "available" healthcare resources (revealed access) is usually much more limited. The objectives of this study were to examine the availability of healthcare resources by measuring the potential access and the revealed access for outpatients who need to access pharmacies to fill prescriptions of Schedule II (CII) opioids for pain management, and to explore the difference between rural and urban residents in these two types of access. About 191,700 prescriptions for CII opioids dispensed in 1997 in the state of Michigan, USA were analyzed. Revealed accessibility was measured by the distance between the paired zip codes of the pharmacy and the patient listed on each prescription. Potential accessibility was measured by the distance from a patient's zip code to that of the nearest community pharmacy that could dispense the opioid prescriptions. The analyses on revealed access showed that 50% of the CII prescriptions were dispensed by pharmacies located within a 5-mile radius of patients' residences, 75% of prescriptions were dispensed within about a 10-mile radius, and 90% were within 20 miles. If patients were free to access the nearest pharmacy for dispensing (a hypothetical situation under potential access), the median, 75th percentile, and 90th percentile distances could reduce to 2, 3, and 5 miles, respectively. Similar differences between revealed and potential access were observed in both rural and urban areas and for every major opioid drug group. We conclude that policymakers should recognize the discrepancy between potential and revealed accessibility and move beyond only considering area configuration of healthcare resources to evaluating and improving access to care.

Quality medical management of the geriatric population using practice guidelines, physician-managed home health services, and continuous quality-improvement management strategies.

One challenge confronting physicians in the 1990s is the delivery of cost-effective quality healthcare to the elderly. Given current utilization, federal expenditures on Medicare and other federal healthcare programs are projected to increase to more than 6% of the gross national product by the year 2030. Physicians' practice habits will have an impact on the cost of caring for the nation's elderly. It is therefore essential for physicians to recognize their role in delivering quality geriatric care. First, they must be active and diligent in the pursuit of practice guidelines that support changes in the current standards of care. Second, physicians should consider alternative approaches to present practice patterns such as physician-managed home health services. Finally, physicians need to take a proactive approach to quality by supporting continuous quality improvement. The purpose of this review is to present some of the existing established practice guidelines, data to support the use of physician-managed home care as an alternative practice approach, and suggestions to incorporate the principles of continuous quality improvement to serve as one practice model that can be used by physicians to improve the quality of medical care given to America's elderly.

Healthcare needs of people with intellectual disability in institutions in Taiwan: outpatient care utilization and implications.

BACKGROUND: The present study assessed the outpatient care use of people with intellectual disability (ID) in order to identify patterns of healthcare needs and the factors affecting this utilization. METHODS: The primary method used in this study was a cross-sectional survey of 1390 subjects with ID in Taiwan. Data were obtained from questionnaires completed at 30 registered institutions caring for people with ID. RESULTS: The findings show that people with ID in Taiwan are likely to make more outpatient visits per year than members of the general population. The prevalence of illness in people with ID was 41%, with epilepsy being the most frequently reported disease. A total of 39.5% of individuals with ID took medicine regularly, and 38.9% had used alternative forms of medication besides Western medicine. In terms of the use of outpatient facilities by people with ID, paediatric clinics were the most frequently utilized. The average monthly number of outpatient visits per person with ID was 2.18 (around 26 visits per year). This study found that the need for outpatient care is determined by a variety of factors relating to: the age of people with ID, the type of handicap, the place of medical treatment, having a family physician, the accessibility of medical care, the time-consuming nature of the medical visits, having an illness, ID accompanied with other disabilities, and finally, a need for rehabilitative care. CONCLUSIONS: From the examination of the expressed needs of people with ID, it was found that these individuals have a heightened need for healthcare and the treatment of special diseases/disorders in comparison to members of the general population in Taiwan. Within the context of ordinary services, it is particularly important to have a precise view of the ways in which the health needs of people with ID are different from the general population as a whole. This will enable healthcare services to respond to these needs, either through support systems within generic care or, in some cases, through the delivery of specific healthcare through specialized services which are kept separate from generic care.

Time series modeling for syndromic surveillance.

BACKGROUND: Emergency department (ED) based syndromic surveillance systems identify abnormally high visit rates that may be an early signal of a bioterrorist attack. For example, an anthrax outbreak might first be detectable as an unusual increase in the number of patients reporting to the ED with respiratory symptoms. Reliably identifying these abnormal visit patterns requires a good understanding of the normal patterns of healthcare usage. Unfortunately, systematic methods for determining the expected number of (ED) visits on a particular day have not yet been well established. We present here a generalized methodology for developing models of expected ED visit rates. METHODS: Using time-series methods, we developed robust models of ED utilization for the purpose of defining expected visit rates. The models were based on nearly a decade of historical data at a major metropolitan academic, tertiary care pediatric emergency department. The historical data were fit using trimmed-mean seasonal models, and additional models were fit with autoregressive integrated moving average (ARIMA) residuals to account for recent trends in the data. The detection capabilities of the model were tested with simulated outbreaks. RESULTS: Models were built both for overall visits and for respiratory-related visits, classified according to the chief complaint recorded at the beginning of each visit. The mean absolute percentage error of the ARIMA models was 9.37% for overall visits and 27.54% for respiratory visits. A simple detection system based on the ARIMA model of overall visits was able to detect 7-day-long simulated outbreaks of 30 visits per day with 100% sensitivity and 97% specificity. Sensitivity decreased with outbreak size, dropping to 94% for outbreaks of 20 visits per day, and 57% for 10 visits per day, all while maintaining a 97% benchmark specificity. CONCLUSIONS: Time series methods applied to historical ED utilization data are an important tool for syndromic surveillance. Accurate forecasting of emergency department total utilization as well as the rates of particular syndromes is possible. The multiple models in the system account for both long-term and recent trends, and an integrated alarms strategy combining these two perspectives may provide a more complete picture to public health authorities. The systematic methodology described here can be generalized to other healthcare settings to develop automated surveillance systems capable of detecting anomalies in disease patterns and healthcare utilization.

Utilization of the Internet to deliver educational materials to healthcare professionals.

We have developed a computer-based learning module which uses three-dimensional animation sequences to enhance the acquisition of physical concepts and skills necessary for clinical evaluation and treatment of the cervical spine. This teaching tool, designed to serve as an adjunct to teaching strategies that faculty may be currently using, is available to students through the Kobiljak Resource Center at Michigan State University College of Osteopathic Medicine (MSUCOM) and via the Internet (http:/(/)hal.bim.msu.edu/EdTech) to individuals and groups who are physically removed from the MSU campus. While we are restricting this initial effort to the upper cervical spine, it is planned that future materials will include other parts of the body and, in addition, will enable students to not only visualize the effects of pathology on motion mechanics, but also give them the ability to interactively control an articulation in three-dimensional space.

Ethical attitudes on human cloning among professionals in Taiwan and the policy implications for regulation.

UNLABELLED: This research focused on understanding the attitudes toward human cloning in Taiwan among professionals in healthcare, law, and religion. DESIGN: The study was conducted utilizing a structured questionnaire. PARTICIPANTS: 220 healthcare professionals from two regional hospitals located in Taipei, 351 religious professionals in the northern Taiwan and 711 legal professionals were selected by to receive questionnaires. The valid response rate is 42.1% MAIN MEASUREMENTS: The questions were generated by an expert panel and represented major arguments in the human cloning debate. There were a total of six Likert scaled questions in the questionnaire. The responses were coded from 1 to 5 with 1 representing strong opposition to human cloning, 3 representing a neutral attitude; and 5 representing a strong favorable attitude toward human cloning. RESULTS: Healthcare professionals had the highest overall average score of 2.14 and the religious professionals had the lowest average at 1.58. All three categories of respondents' attitude toward cloning ranged from mild opposition to strong opposition to human cloning. The religious professionals were more strongly opposed to cloning. Age, education, and religion significantly influenced attitudes toward cloning. Professionals between fifty-one and sixty years old, those with less education, and Roman Catholic professionals were more strongly opposed to cloning. CONCLUSIONS: Religious professionals were more strongly opposed to human cloning than professionals in healthcare or law. Younger professionals as an age group demonstrated less opposition to human cloning. Regulation of human cloning will be influenced by professionals in healthcare, law, and religion, and the regulatory environment chosen now will play a pivotal role in influencing the acceptance of human cloning in the future.

Using GIS in government: an overview of the VHA's Healthcare Atlas, FY-2000.

The amount of VA data available for analysis can be overwhelming to individuals who need to translate these data into usable information. The Atlas, using current GIS technology, was funded to provide data in a comprehensive guide. Patients were identified using a disease classification scheme based on Kaiser Permanente methodology and the Clinical Classifications Software (AHRQ). Utilization data were extracted from the Medical SAS Datasets. Cost data were obtained from the HERC. GIS tools were used to create the Atlas. The Atlas overviews the location of VA hospitals; profiles veteran, VA enrollee and patient populations; examines overall utilization; depicts patterns in healthcare use by specific disease cohorts; and examines geographic variations in costs. This product will enhance knowledge of VA's enrolled patient population and their healthcare needs, and provide background information that will improve the formulation of specific research questions to address those needs.

Outcomes associated with a home care telehealth intervention.

To determine whether adding telehealth technology to traditional home care services increases health-related quality of life (HRQOL) and home care satisfaction, and decreases resource utilization among home care patients. This trial included 37 home care patients receiving services in a Veterans Affairs medical center, randomized into intervention and control groups. Outcome measures included patient satisfaction and HRQOL at baseline and 6-month follow- up, and the use of inpatient and outpatient services before and during the 6-month study period. Intervention group patients reported greater improvement in the mental health component of HRQOL, (t = 2.27; df = 15; p = 0.04). Satisfaction with the telehealth equipment was high (means exceeded 4.0 on six measures ranging from 1-5). However, no statistically significant differences were observed between intervention and control groups in terms of changes in physical health, inpatient admissions, bed days of care, emergency department visits, or general satisfaction with home care services. Intervention group members did show a trend (p = 0.10) toward fewer overall outpatient visits (mean = 29.1; standard deviation [SD] +/- 30.1) compared to those receiving traditional home care services (mean = 38.9; SD +/- 28.9) The use of telehealth services as an adjunct to traditional home care is associated with greater improvements in mental health status and a trend toward lower use of inpatient and outpatient healthcare services. Further work, utilizing larger sample sizes, is needed to investigate the relationship between telehealth services, the use of healthcare resources, and other outcomes.

[Geriatric outpatient healthcare: hierarchical demand structuring].

In Brazil, the rapid growth of the elderly population has been causing a great impact on the healthcare system, with increased costs and service utilization. The inefficiency of traditional models for geriatric healthcare has made it essential to change the healthcare concepts for this population. This can take place through the development of new healthcare models that include the means to identify, assess and treat elderly patients with a variety of morbid and functional conditions, and which can be applied diverse healthcare scenarios. An outpatient model is proposed, with two stages that differ in the depth and coverage of their actions. These stages are organized as increasing levels of complexity and are capable of selecting subgroups of individuals that, because of their risk characteristics, should follow different paths through the healthcare structure. This paper discusses the first stage of this model, which involves risk identification among large groups of elderly people, by means of structuring a hierarchical flow of actions and using assessment tools of adequate sensitivity and specificity. Individuals aged 65 years or over who are detected through walk-in outpatient consultation, home visits or telephone interview are classified using a rapid screening risk evaluation instrument composed of eight items. Depending upon the level of risk presented, the individual will either be referred to another level of functional evaluation (medium-high and high risk levels), or to normal clinical care and old people's community centers (low and medium risk levels). The second stage will be the subject of a subsequent paper.

[Utility of the Pediatric Appropriateness Evaluation Protocol (pAEP) to detect deficiencies in the healthcare circuit].

OBJECTIVES: To quantify the number of inappropriate pediatric hospital admissions using the Pediatric Appropriateness Evaluation Protocol (pAEP), the causes of inappropriate admissions, and the clinical utility of the paep, as well as to detect deficiencies in the healthcare circuit in hospitalized pediatric patients. MATERIAL AND METHODS: A prospective, descriptive study was carried out in a sample of 236 pediatric admissions. We analyzed several items such as age, pAEP, factors associated with inappropriate admission, main and secondary diagnoses, the diagnostic tests motivating admission, and day of the week and month of admission. RESULTS: A total of 13.6 % (CI: 9.5 %-18 %) of pediatric admissions were inappropriate. The most frequent reasons for inappropriate admissions were diagnostic tests (2.5 %) and treatment (11 %) that could have been performed on an outpatient basis. Most (90.6 %) of the admissions deemed inappropriate by the pAEP were also considered inappropriate when evaluated by experienced pediatricians. CONCLUSIONS: Improvement of healthcare circuits could decrease inappropriate admissions (better coordination between primary care and hospitals and improved access from the emergency unit to the specialized pediatric outpatient service). The pAEP allows identification of inappropriate admissions and their causes, as well as detection of deficiencies in the healthcare circuit.

[Humanization of healthcare services and the right to healthcare].

This article discusses the possibilities and limits of proposals for the humanization of healthcare. The theoretical references utilized are the concept of "reification" as a causative explanation for the process of man's estrangement from his world and the concept of "radical needs" as a possible way of overcoming traditionalist humanism to achieve transformative practice. From these notions, an understanding of the difficulties and contributions of the movement towards humanization is sought, highlighting the interdependence and limits of sectoral changes within healthcare in light of society's concepts and general values. The article concludes by suggesting that guidelines for humanization/satisfaction, in bringing together the critique of society's general questions concerning the daily difficulties of healthcare services, may keep the comprehensiveness of the right to healthcare open beyond the limits of current social relations, thereby favoring a stance that opposes the restrictive trend of minimal public policies towards healthcare.

Cost of health care for a community of older adults in an urban academic healthcare system.

BACKGROUND: Urban academic medical centers provide care for large populations of vulnerable older adults. These patients often suffer a disproportionate share of chronic illnesses, disabilities, and social stressors that may increase health care costs. OBJECTIVE: To describe the distribution and content of total healthcare costs accrued over a 4-year period by a community of older adults cared for in an urban academic healthcare system and to describe high-cost patients and utilization patterns. DESIGN: A cohort study. SETTING: A tax-supported public healthcare system consisting of a 450-bed hospital and seven community-based ambulatory care centers. PATIENTS: 12,581 patients aged 60 years and older who had at least two ambulatory visits and/or one hospitalization within the healthcare system from 1993 through 1995. MEASUREMENTS: Patient demographic and clinical characteristics, hospital and ambulatory utilization rates, and all healthcare costs accrued from 1993 through 1996 were determined. Costs were estimated from the perspective of the healthcare system using cost to charge ratios. MAIN RESULTS: The mean patient age was 70 years, 60% were women, 44% were Black, and 83% were covered by Medicare and/or Medicaid. Nearly 25% of patients were obese, 15.8% had a history of smoking, and 15.5% had evidence of malnutrition. The mean number of ambulatory visits per year was 4.3 (+/-7.2), and 38.1% of patients had been hospitalized one or more times. Within the 4-year window, 24.1% of patients had missed five or more appointments with their primary care physicians, 32.7% of patients had five or more unscheduled clinic visits, and 12.5% had five or more emergency room visits. Total health care costs for 4 years for this cohort of older adults was $125.2 million dollars, with per capita annual mean costs of $3893. Expenditures associated with hospitalizations accounted for 63.6% of healthcare costs. Total inpatient and outpatient costs for the 38% of patients hospitalized at least once accounted for 85.3% of all health care expenditures. Patients who died in the hospital did not accrue significantly greater costs than patients who died out of the hospital. Simulations of a random 5% adverse selection of high-cost patients among two capitated systems resulted in cost shifts of $11.1 million. Recorded smoking history, obesity, and low serum albumin were significantly associated with excess costs. CONCLUSIONS: Healthcare costs are concentrated in a significant minority of older adults. Costs accrued in conjunction with hospital stays dominate healthcare expenditures for this cohort of older adults. However, most older adults (83%) have one or fewer hospital episodes in a 4-year period. Although patients who died accrued greater healthcare costs, these costs were not higher when the death occurred in the hospital. Self-care behaviors are an important target for interventions to reduce costs.

Telemedicine, the Internet, and world wide web: overview, current status, and relevance to surgeons.

The Information Age has made profound changes in society and is slowly entering the healthcare field. Some of the most important areas are telemedicine, the Internet, and the world wide web (www). Millions of physicians, healthcare providers, and patients are accessing the web daily for patient information, consultation, and distant learning. Telemedicine is beginning to enter the mainstream of health care after decades of demonstration projects. There are many issues which have been raised, such as access to the information, the security of the information, and the quality of the content on the web. While telemedicine is beginning to Hower, there are numerous barriers that prevent its rapid implementation, such as licensure, reimbursement, liability, quality of service, and technical issues. In spite of the numerous challenges, telemedicine over the Internet was practiced in one of the most remote areas of the world--Mt. Everest--demonstrating that it is possible to utilize all the latest healthcare telecommunications tools in even the most extreme of settings.

Cost effectiveness of pramipexole in Parkinson's disease in the US.

OBJECTIVE: Pramipexole was recently approved in the US for treatment of the symptoms of idiopathic Parkinson's disease (PD). Although pramipexole has been found to be safe and efficacious when compared with placebo, little data are yet available on its cost effectiveness when compared with baseline treatment. The aim of this study was to estimate the costs and cost effectiveness (cost utility) of pramipexole compared with baseline treatment in patients with early and advanced PD. DESIGN AND SETTING: We developed a cost-effectiveness (CE) model in the US setting that linked Unified Parkinson's Disease Rating Scale (UPDRS) Part II (activities of daily life) and III (motor) scores to disease progression, costs and patient utility. Data for the model were obtained from clinical trials, a literature review and a survey of 193 patients' health resource use and utility. We used cost and quality-adjusted life-year (QALY) estimates from the model to estimate the incremental cost effectiveness of pramipexole relative to baseline treatment patterns. We performed separate analyses for patients with early and advanced PD. We also performed extensive sensitivity analyses by adding other dopamine agonists to the no-pramipexole treatment regimen and varying disease progression parameters. The study was conducted from the societal perspective, although data presentation allows interpretation of cost effectiveness from either the societal or payer perspective. MAIN OUTCOME MEASURES AND RESULTS: For patients with both early and advanced PD, treatment with pramipexole had higher costs but was more effective than baseline treatment. For patients with early onset of PD, the incremental total CE ratio for pramipexole was $US8837/QALY. For patients with advanced PD, the incremental CE ratio was $US12 294/QALY (1997 costs). These ratios were lower than the CE ratios of many widely used medical treatments. CONCLUSIONS: Subject to the inherent limitations of modelling chronic disease progression and subsequent healthcare costs and patient utility, the results suggested that pramipexole was a cost effective treatment for patients with early and advanced PD in the US.

An investigation of the effects of a healthcare provider network on costs and lost time in workers' compensation.

OBJECTIVE: The objective of this study was to evaluate the number of lost time days and cost of workers' compensation claims at a median claim duration (maturity) of 25 months for individuals injured between August 1, 2003, and July 31, 2004, who chose a statewide (Louisiana) network (Omnet Gold) of healthcare providers not subject to utilization review. METHODS: We identified and contrasted 176 lost time claims (143 closed) managed by Omnet Gold (OG) healthcare providers and 1464 lost time claims managed by healthcare providers not participating in OG. RESULTS: The average frequency of lost workdays for a closed OG claim was 53 days versus 99 days for a closed non-OG claim and the average cost of a closed OG claim was 12,554 dollars, whereas the average cost of a closed non-OG claim was 20,400 dollars. Both days lost from work and costs were significantly lower among claims managed by OG healthcare providers. This outcome was consistent with the findings of a previous study performed on the same claims in which a significant difference was demonstrated analyzing primarily open (unresolved) claims with a median claim duration of 6 months. The ability of OG healthcare providers to return a higher proportion of injured workers to work early and shorten claims durations were the major factors influencing these outcomes. CONCLUSIONS: In a state where claimants are permitted choice of medical provider, a network of healthcare providers can achieve superior lost time and cost outcomes than out of network healthcare providers.

Managed care penetration, insurance status, and access to health care.

BACKGROUND: Access to health care, reflected by an ability to meet one's health needs, is influenced by individual characteristics and the environment. Although managed care activity influences healthcare prices and overall utilization, its relationship to access and its broader effects across different insurance categories has not been well studied. OBJECTIVE: To examine the association between managed care activity and individuals' access to care, and to assess differences in this relationship by insurance status. RESEARCH DESIGN: Cross-sectional survey of households conducted in 1998. SUBJECTS: A sample of 15,613 adult Ohio residents. MEASURES: Self-reported difficulties in obtaining health care, medications, supplies, or medical equipment in the past year. RESULTS: A total of 1248 (8.0%) identified an access problem. In bivariate analyses, these problems were more common among continuously and intermittently uninsured individuals compared with those who were continuously insured during the previous 12 months (P<0.001) and also among those living in areas with more managed care (P=0.01). After accounting for other individual and environmental characteristics in hierarchical analyses, individuals residing in areas with more managed care had 28% higher odds of reporting problems obtaining care than those elsewhere (multivariate odds ratio, 1.28; 95% confidence interval, 1.04-1.58]; P=0.02). No significant interaction between managed care penetration and insurance status was observed. CONCLUSIONS: Greater managed care activity is associated with unfavorable patterns of healthcare access despite an individual's insurance status, suggesting more pervasive effects. Unintended effects should be carefully evaluated when formulating future programs that seek to address disparities in access to care.
