Internet-based monitoring and benchmarking in ambulatory surgery centers.

BACKGROUND: Each year the number of surgical procedures performed on an outpatient basis increases, yet relatively little is known about assessing and improving quality of care in ambulatory surgery. Conventional methods for evaluating outcomes, which are based on assessment of inpatient services, are inadequate in the rapidly changing, geographically dispersed field of ambulatory surgery. Internet-based systems for improving outcomes and establishing benchmarks may be feasible and timely. METHODS: Eleven freestanding ambulatory surgery centers (ASCs) reported process and outcome data for 3,966 outpatient surgical procedures to an outcomes monitoring system (OMS), during a demonstration period from April 1997 to April 1999. ASCs downloaded software and protocol manuals from the OMS Web site. Centers securely submitted clinical information on perioperative process and outcome measures and postoperative patient telephone interviews. Feedback to centers ranged from current and historical rates of surgical and postsurgical complications to patient satisfaction and the adequacy of postsurgical pain relief. RESULTS: ASCs were able to successfully implement the data collection protocols and transmit data to the OMS. Data security efforts were successful in preventing the transmission of patient identifiers. Feedback reports to ASCs were used to institute changes in ASC staffing, patient care, and patient education, as well as for accreditation and marketing. The demonstration also pointed out shortcomings in the OMS, such as the need to simplify hardware and software installation as well as data collection and transfer methods, which have been addressed in subsequent OMS versions. DISCUSSION: Internet-based benchmarking for geographically dispersed outpatient health care facilities, such as ASCs, is feasible and likely to play a major role in this effort.

Access, satisfaction, and utilization in two forms of Medicaid managed care.

We determined access and satisfaction of 2,598 recipients of Virginia's Medicaid program, comparing its health maintenance organizations (HMOs) to its primary care case management (PCCM) program. Positive responses were summed as sub-domains either of access, satisfaction, or of utilization, and adjusted odds ratios were calculated for HMO (vs. PCCM) sub-domain scores. The response rate was 47 per cent. We found few significant differences in perceived access, satisfaction, and utilization. Both HMO adults and children more often perceived good geographic access (adults, OR, [CI] = 1.50, [1.04-2.16]; children, OR, [CI] = 1.773 [1.158, 2.716]). But HMO patients less often reported good after-hours access (adults, OR, [CI] = 0.527 [0.335, 0.830]; children, OR, [CI] = 0.583 [0.380, 0.894]). Among all patients reporting poorer function, HMO patients more often reported good general and preventive care (OR, [CI] = 2.735 [1.138, 6.575]). We found some differences between Medicaid HMO versus PCCM recipients' reported access, satisfaction, and utilization, but were unable to validate concerns about access and quality under more restrictive forms of Medicaid managed care.

Effect of different types of Medicaid managed care on childhood immunization rates.

Medicaid managed care can improve access to prevention services, such as immunization, for low-income children. The authors studied immunization rates for 7,356 children on Medicaid in three managed care programs: primary care case management (PCCM; n = 4,605), a voluntary HMO program (n = 851), and a mandatory HMO program (n = 1,900). Immunization rates (3:3:1 series) in PCCM (78%) exceeded rates in the voluntary HMO program (71%), which in turn exceeded those in the mandatory HMO program (67%). Adjusting for race, urban residence, and gender, compared to children in PCCM, children in the voluntary HMO program were less likely to complete the 3:3:1 series (OR = 0.75, CI = 0.63, 0.90), and children in the mandatory HMO program were even less likely to complete the series (OR = 0.59, CI = 0.51, 0.68). Results differed by individual HMOs. Monitoring of outcomes for all types of managed care by Medicaid agencies is imperative to assure better disease prevention for low-income children.

Assessing Medicaid recipient access and satisfaction. Fee-for-service, case management, and capitation.

Medicaid increasingly requires enrollment in managed care programs. This study assessed access to care, satisfaction with care, and appointment wait times during the transition from fee for service to managed care using three annual Medicaid recipient surveys. There was little evidence of dissatisfaction or poorer access among managed care recipients. Fee-for-service recipients, compared to primary care case management, reported greater general (91 vs. 78%, p < .01) and specialty care access (92 vs. 80%, p < .01). When appointments were required, adult HMO enrollees, compared to case management, had longer waits for routine care in the second (5.8 +/- 8.2 days vs. 4.0 +/- 6.6) and third surveys (5.5 +/- 6.9 days vs. 3.8 +/- 7.3); waits for other appointments did not consistently differ by program. There were no significant program differences in overall satisfaction. Findings are tempered by the potential for response bias and geographic confounding. Continued monitoring is crucial to assure that access and satisfaction remain high in Medicaid managed care.

The impact of disease management on outcomes and cost of care: a study of low-income asthma patients.

An asthma disease management program designed specifically for low-income patients experiencing significant adverse events can improve health outcomes substantially, while lowering costs. The Virginia Health Outcomes Partnership aimed to help physicians in a fee-for-service primary care case management program manage asthma in Medicaid recipients. Approximately one-third of physicians treating asthma in an area designated as the intervention community volunteered to participate in training on disease management and communication skills. This large-scale study discovered that the rate of emergency visit claims for patients of participating physicians who received feedback reports dropped an average of 41% from the same quarter a year earlier, compared to only 18% for comparison community physicians. Although only a third of the intervention community physicians participated in the training, emergency visit rates for all intervention community physicians nonetheless declined by 6% relative to the comparison community among moderate-to-severe asthma patients when data for participating and nonparticipating physicians were combined. At the same time, the dispensing of some reliever drugs recommended for asthma increased 25% relative to the comparison community. A cost-effectiveness analysis projected direct savings to Medicaid of $3 to $4 for every incremental dollar spent providing disease management support to physicians. The results of this study demonstrate the potential this program offers, especially for Medicaid programs in other states that want to improve the care of their primary care case management networks and, at the same time, manage costs.

System change: quality assessment and improvement for Medicaid managed care.

Rising Medicaid health expenditures have hastened the development of State managed care programs. Methods to monitor and improve health care under Medicaid are changing. Under fee-for-service (FFS), the primary concern was to avoid overutilization. Under managed care, it is to avoid underutilization. Quality enhancement thus moves from addressing inefficiency to addressing insufficiency of care. This article presents a case study of Virginia's redesign of Quality Assessment and Improvement (QA/I) for Medicaid, adapting the guidelines of the Quality Assurance Reform Initiative (QARI) of the Health Care Financing Administration (HCFA). The article concludes that redesigns should emphasize Continuous Quality Improvement (CQI) by all providers and of multi-faceted, population-based data.

Psychopathology and pain in medical in-patients predict resource use during hospitalization but not rehospitalization.

The authors investigated the relationship between psychopathology and resource use in general medical in-patients during hospitalization and rehospitalization. Between 1 July 1987, and 30 April 1989, 1020 in-patients were prospectively screened for depression, anxiety, cognitive dysfunction, and pain. Overall, the screen identified 47% of patients as having high psychopathology or pain, including 25.7% depressed, 21.8% anxious, 17.6% with cognitive dysfunction, and 5.2% with high pain. There were no measured differences in demographics or disease severity between high and low psychopathology groups. High psychopathology patients had longer stays and higher costs during the index hospitalization but there were no differences during subsequent hospitalizations. Length of stay declined overall during the study period, but there were no changes over time in the association between high psychopathology or pain with increased resource use. The measured symptoms of psychopathology and pain we measured are associated with increased short-term utilization of health care resources, but the increase does not extend to subsequent hospitalizations. Outcome studies aiming to reduce psychopathology in medical in-patients should pay particular attention to short term costs.

A randomized controlled study of psychiatric consultation guided by screening in general medical inpatients.

OBJECTIVE: The purpose of the study was to test the hypothesis that psychiatric consultation would reduce health care utilization during and after medical hospitalization. METHOD: A randomized, double-controlled clinical trial of psychiatric consultation was conducted on the general medical inpatient services of a university hospital. After meeting inclusion criteria, 1,541 patients were screened for depression, anxiety, confusion, and pain over a period of 21 months. The 741 patients with high levels of psychopathology or pain were subdivided into baseline control subjects (N = 232), contemporaneous control subjects (N = 253), and an experimental consultation group (N = 256). The major outcome measures were length of hospital stay and hospital costs. Secondary outcome measures were posthospital health status, rehospitalization rates, and use of outpatient medical care. RESULTS: This study did not demonstrate an effect of experimental psychiatric consultation on hospital resource use or posthospital medical care utilization after adjustment was made for disease severity. Hospital resource use decreased in the entire sample over the 21-month duration of the study. CONCLUSIONS: The brief, efficient screen for anxiety, depression, confusion, and pain identified a group of patients who also used more hospital resources, but a single experimental psychiatric consultation did not reduce costs. The double-controlled nature of the design proved essential to avoid being misled by background changes in hospital resource use.

How the elderly fare in HMOs: outcomes from the Medicare competition demonstrations.

Because of concern about the effects of prepaid care on outcomes for elderly enrollees in health maintenance organizations (HMOs), a prospective study of access to care and functional outcomes was performed. HMOs with Medicare risk contracts in January 1985 (N = 17) were selected from ten communities and were matched for comparison with ten similar communities where no Medicare HMOs were in operation. Random samples of HMO enrollees (N = 2,098) and fee-for-service (FFS) nonenrollees (N = 1,059) were assessed at baseline and at follow-up one year later (HMO = 1,873, FFS = 916) to observe access to care and functional outcomes. At baseline, nonenrollees had more bed days and poorer functional status than HMO enrollees. While fewer HMO enrollees experienced declines in functional status between baseline and follow-up (e.g., patient's ability to function declined in one or more activities of daily living: HMOs at 5.3 percent versus FFS at 8.5 percent, p < .01), after controlling for other factors with logistic regression, enrollment status was not significantly associated with functional decline. Self-rated health, history of hospitalization, age of 80 or older and baseline functional status were predictive of decline in function. After controlling for baseline differences, HMO disenrollees also experienced similar functional declines at follow-up compared to continuously enrolled beneficiaries. These findings suggest that Medicare beneficiaries who belong to HMOs experience comparable rates of functional decline to those experienced by beneficiaries in the FFS sector with similar initial levels of function and health status. Together with results showing no significant difference in medical visits according to various symptoms, we conclude that access and quality of care delivered by HMOs is comparable to that provided in FFS settings.

Relation of psychopathology in general medical inpatients to use and cost of services.

The authors investigated the relation between psychopathology in medically ill inpatients and use and cost of medical care services. Of 455 medical inpatients, the Medical Inpatient Screening Test identified 27.9% as very depressed, 27.5% as very anxious, 20.2% as having cognitive dysfunction, and 8.6% as having high pain levels. Overall, the test identified 51% of the patients as having high levels of psychopathology or pain. These subjects had a 40% longer median length of hospital stay and 35% greater mean hospital costs than those with low levels of psychopathology or pain. Patients with greater psychopathology also had higher hospital charges, more procedures during hospitalization, and more discharge diagnoses but did not differ from the other patients in sex, race, age, diagnosis-related group (DRG) major diagnostic category, or DRG weight.

Payment to health maintenance organizations and the geographic factor.

The adjusted average per capita cost (AAPCC) payment system for Medicare risk-based plans uses a county level geographic adjustment factor to account for differences in beneficiary costs across areas. The implications of abandoning the county unit as the basis of the geographic area are examined and the merging of counties to match the geographic definition used in the prospective payment system are considered. Year-to-year variation in a county AAPCC is inversely associated with county population size and, based on year-to-year AAPCC variation, 86 percent of all counties are too small to be used for the geographic adjustment.

Patient satisfaction among elderly enrollees and disenrollees in Medicare health maintenance organizations. Results from the National Medicare Competition Evaluation.

More than 1 million Medicare beneficiaries have enrolled in health maintenance organizations (HMOs) and competitive medical plans under a new program in which beneficiaries can freely enroll in a risk-based HMO in their area or remain in the fee-for-service sector under Medicare. Based on a randomly selected nationwide sample of beneficiaries, we analyzed differences in patient satisfaction between 2091 beneficiaries who were continuously enrolled in an HMO plan for 1 year and 1000 beneficiaries in the fee-for-service sector. We also studied the reasons for disenrollment. No significant difference in overall satisfaction was found between HMO enrollees and fee-for-service beneficiaries. However, HMO enrollees expressed less satisfaction compared with fee-for-service beneficiaries regarding the professional competence of their health care providers and the willingness of the HMO staff to discuss problems. On the other hand, HMO enrollees were more satisfied than fee-for-service beneficiaries with waiting times and claims processing. Approximately half of the disenrollment from an HMO within 1 year was attributed to misunderstanding the terms of enrollment.

Evaluation of the Medicaid competition demonstrations.

In 1983, the Health Care Financing Administration funded a multiyear evaluation of Medicaid demonstrations in six States. The alternative delivery systems represented by the demonstrations contained a number of innovative features, most notably capitation, case management, limitations on provider choice, and provider competition. Implementation and operation issues as well as demonstration effects on utilization and cost of care, administrative costs, rate setting, biased selection, quality of care, and access and satisfaction were evaluated. Both primary and secondary data sources were used in the evaluation. This article contains an overview and summary of evaluation findings on the effects of the demonstrations.
