The outcomes of elective laparoscopic and open cholecystectomies.

BACKGROUND: The demand for evidence of effectiveness for medical care has prompted the development of epidemiologic approaches to relating the outcomes of care to treatment. This study compares the outcomes of care for patients undergoing the newly introduced laparoscopic cholecystectomy with the results from conventional open cholecystectomies. METHODS: Consecutive cases of elective cholecystectomy from 35 hospitals (all of the metropolitan and selected rural hospitals in Minnesota) were enrolled in the study. Patients were interviewed on admission to establish baseline symptoms and functional status and to confirm risk factors. Their medical records were abstracted to yield information on risk factors, treatment, and hospital complications. To establish outcomes, patients were sent a questionnaire about their symptoms and functional status six months postoperatively. RESULTS: Of 3,448 patients studied, 2,490 (72 percent) had a laparoscopic procedure, including 195 cases that were converted to open cholecystectomies. Functional status data were obtained on 2,481 cases (76 percent). Laparoscopic operation was associated with more operative complications (odds ratio 3.02, p < 0.001), but with fewer general complications (odds ratio 0.32, p < 0.001). The mean time to return to work was 15 days for laparoscopic cases compared to 31 days for open procedures (p < 0.001). The only functional outcome difference between the two procedures was that patients who underwent laparoscopic cholecystectomies were more likely than those with conventional cholecystectomies to be able to perform their usual activities at follow-up evaluation (p < .001). There was evidence of a learning curve; the more laparoscopic procedures a surgeon performed, the fewer the operative (p < 0.01) and general (p < 0.0001) complications. There was no indication that the availability of laparoscopic operation was associated with more operations being performed. CONCLUSIONS: Laparoscopic operation seems to represent a significant advance in getting patients back to a normal life sooner. More attention needs to be given to which patients are most likely to benefit from cholecystectomy of either type. Epidemiologic approaches can be useful in assessing the effectiveness of care. Partnerships between providers and researchers can produce useful effectiveness data by supplementing available clinical records with more detailed outcome data.

Head injury in partner-abusive men.

Research into etiology of marital aggression has focused primarily on psychosocial, political, and cultural factors, to the exclusion of physiological influences. Fifty-three partner abusive men, 45 maritally satisfied, and 32 maritally discordant, nonviolent men were evaluated for past history of head injury, by a physician who was not informed of group membership and aggression history. Logistic regressions confirmed that head injury was a significant predictor of being a battered. The implications of these findings for both marital aggression and post-head injury rehabilitation are discussed.

Chronic conditions that lead to functional limitation in the elderly.

BACKGROUND: The role of chronic medical conditions in elderly persons' loss of functional abilities is intuitively important but not well defined. This analysis was designed to identify chronic medical conditions that lead to the development of severe functional limitation. METHODS: Functionally intact members of a multistage probability sample (n = 6,862) of all noninstitutionalized U.S. civilians age 70 years or older were interviewed in 1984. Based on data from the National Death Index and from follow-up telephone interviews in 1988 with survivors, subjects were classified as functionally intact, functionally limited (unable to perform one or more of seven essential activities), or decreased. RESULTS: After adjusting for the effects of exercise habits and demographic, socioeconomic, and psychosocial factors, we found that the best predictors of the development of functional limitation were cerebrovascular disease (OR = 2.14; 95% CL = 1.16, 3.98) and arthritis (OR = 1.51; 95% CL = 1.08, 2.11). The contribution of coronary artery disease also approached statistical significance (OR = 1.49; 95% CL = 0.99, 2.27). CONCLUSION: In the future, the primary prevention or effective treatment of cerebrovascular disease, arthritis, and possibly coronary artery disease may produce a modest reduction in the incidence of severe functional limitation.

Looking for physical therapy outcomes.

Assessing the outcomes of physical therapy will be difficult in many instances, because it is difficult to separate the specific contribution of physical therapy from the effects of overall rehabilitative efforts. Nonetheless, more studies are needed to establish what works, both specifically and overall. Appropriate care should be defined on the basis of what has been shown to be effective. In most instances, this knowledge will come from quasi-experimental designs that utilize epidemiological methods. In designing effectiveness studies, careful attention needs to be paid to defining the treatment in terms of type and amount of care. Other factors that will affect the outcome, including baseline performance, risk factors, and environment, must be adequately dealt with in the analysis. Rehabilitation's success depends on the patient's performance in his or her actual living situation, not just in a controlled environment. Blaming the community for failing to provide a supportive environment will not exonerate rehabilitation's responsibility.

A controlled trial of outpatient geriatric evaluation and management.

OBJECTIVE: To evaluate the effects of targeted outpatient geriatric evaluation and management (GEM). DESIGN: Controlled clinical trial. Elderly persons were identified as being at high risk for hospital admission on the basis of their responses to a short, mailed, self-administered questionnaire. The high-risk elders who chose to participate in the GEM program were compared to those who continued to receive usual care. SETTING: Outpatient GEM clinic at an urban university hospital. SUBJECTS: Elderly Medicaid recipients whose probability of repeated hospital admission (Pra) within 4 years was calculated as 40% or greater (Pra > or = 0.40). MAIN OUTCOME MEASURES: Mortality, use of institutional services, satisfaction. RESULTS: Of the 1210 persons who were sent questionnaires, 624 responded (response rate = 51.6%), of whom 154 (24.7%) were deemed to be a high risk for hospitalization. Of these, 43 received GEM (experimental subjects); 111 received usual care (controls). At baseline, the experimental and control groups' demographic and health-related characteristics did not differ significantly. The average experimental subject was 76.5 years old, had 9.6 significant medical problems, and took 6.7 significant long-term prescription medications. During the program's first 17 months of follow-up, the experimental subjects had lower annual rates of mortality (2.9% vs 19.2%, P = 0.03) and emergency room use (0.6 vs 1.0 visits, P = 0.01) than did the controls. The experimental subjects also tended to use nursing homes, but not hospitals, at a lower rate than the controls. All of the experimental subjects rated the program as either excellent (81.0%) or good (19.0%); 100% said they would recommend it to others. Their established primary physicians rated the GEM services as appropriate and helpful. CONCLUSION: Targeted outpatient GEM was associated with reduced mortality, reduced use of emergency rooms, and a trend toward reduced use of nursing homes.

Implications of the Clinton health reform plan for older persons and long-term care.

The Clinton plan for older persons and those in need of long-term care offers short-term problems and long-term promises. Final judgment depends in part on the level of commitment assumed for various aspects of the plan. In the near term, even under the best scenario, there will be problems of discoordination as certain groups (like the dually eligible and those needing long-term care) are caught in the gaps between the new and the old. In the longer term, there are potential gains from a more integrated system of care that can accommodate both acute and chronic care and eliminate the administrative incentives to shift fiscal responsibility. Medicare was passed in an effort to correct a disparity. It would be ironic if its existence created a new one. At the same time, older persons are currently better served than many uninsured younger persons. Before they open their mouths to grab for the bone in the water, they had best hang on to the one they have.

Post-hospital home health care for Medicare patients.

Medicare patients in five diagnosis-related groups (DRGs) associated with heavy use of post-hospital care discharged from 52 hospitals in 3 cities were followed up at 6 weeks, 6 months, and 1 year to determine the factors associated with their being discharged home with or without home health care and the correlates of improvement in their functional status. Models correctly predicted those discharged home from those going to institutions in a range from 54 to 82 percent of cases. The amount of the variance in the change in function for those who went home (with or without home health care) explained by the models tested ranged from 19 percent to 73 percent. Total Medicare costs for the patients who went home were considerably less in the year subsequent to the hospitalization compared with those discharged to institutional care.

Perspectives on home care quality.

Home care quality assurance (QA) must consider features inherent in home care, including: multiple goals, limited provider control, and unique family roles. Successive panels of stakeholders were asked to rate the importance of selected home care outcomes. Most highly rated outcomes were freedom from exploitation, satisfaction with care, physical safety, affordability, and physical functioning. Panelists preferred outcome indicators to process and structure, and all groups emphasized "enabling" criteria. Themes highlighted included: interpersonal components of care; normalizing life for clientele; balancing quality of life with safety; developing flexible, negotiated care plans; mechanisms for accountability and case management. These themes were formulated differently according to the stakeholders' role. Providers preferred intermediate outcomes, akin to process.

Informal care substitution: what we don't know can hurt us.

Empirical studies focusing on the relationship between formal and informal home care do little to quell the fears of policymakers that expanded access to public home care services will result in the withdrawal of informal support. A close examination of the studies designed to measure the withdrawal of informal support justifies this skepticism. Concerns about the withdrawal of informal care may hinder the introduction of more extensive home care benefits. Researchers have come some distance in trying to address this policy question. The conflicting nature of empirical findings, thus far, demonstrates that the answer depends heavily on how the question is framed, how home care is measured and over what time frame, and what sorts of analytic approaches are used to model the relationship between formal and informal community-based care. This article discusses these issues in greater detail and suggests strategies to address these problems in future research.

Differences between nursing home admissions and residents.

The use of a cross-sectional sample of nursing home residents rather than a sample of admissions to estimate admission characteristics carries a potential bias. The purpose of this study was to fill this void by comparing abstracted records data for an admissions cohort (n = 1,118) and a residents cohort (n = 830) residing in the same nursing homes. Compared to residents, admissions were significantly more dependent in their ability to get around and to dress themselves, received more clinical services, and had a higher rate of medication use. Over a 12-month period, admissions had a fivefold greater likelihood of being discharged to community, but about the same mortality rate as residents. Within both groups, those discharged to the community as well as those who died had expenditures that were almost twice as high as those of their counterparts who remained alive in the nursing home.
