Predictors of medical care utilization by independently living adults with spinal cord injuries.

A prospective study of 87 independently living adults with spinal cord injury (SCI) as a major disabling condition showed the following average annual health care utilization rates: 1.3 hospital admissions, 16.8 days hospitalized, 1.7 emergency room (ER) visits, and 22.4 outpatient contacts (in person or by telephone). Those hospitalized (n = 66) experienced a mean of 22.2 days hospitalized per person per year. Mean length of stay (LOS) was 11.1 days per admission. Stepwise regression analysis indicated no statistically significant (p less than or equal to .05) predictors of hospital admissions. There were three independent predictors of days hospitalized (greater age, fewer years of education, and more days hospitalized during the previous year), three predictors of days hospitalized for those hospitalized only (greater age, fewer years of education, and longer hospital LOS during the previous year), one predictor of LOS (self-assessment of health), three of emergency room (ER) visits (more unmet instrumental activities of daily living needs, lack of organizational memberships, and more ER visits during the previous year), and five predictors of outpatient contacts (greater age, less satisfaction with health care providers' expressions of concern for their health, lower frequency of leaving apartments, lower levels of life satisfaction, and nonparticipation in a managed medical care demonstration project). Many predictors of health services utilization are immutable. However, changes which facilitate social interaction and changes in the organization of health services may reduce certain types of medical care utilization by people with SCI.

The epidemiology of medical care utilization by severely-disabled independently-living adults.

A prospective study of the medical care utilization experience of 205 severely-disabled independently-living adults in Eastern Massachusetts shows that there was a mean of 0.83 +/- 1.26 hospital admissions, 9.9 +/- 22.7 hospital days, 1.5 +/- 2.31 emergency room (ER) visits, and 26.88 +/- 44.4 outpatient contacts per person per year. Among those hospitalized, the mean experience was 16.2 +/- 27.1 days per person per year; mean length-of-stay was 9.3 +/- 14.7 days per admission. Regression analysis indicates that those with spinal cord injuries as major disabling conditions were significantly more likely to be hospitalized. So were those with lower self-assessments of health, higher levels of depressions, and more baseline ER visits. Self-assessment of health is a significant predictor of hospital days for the total cohort (including those with no admissions); so are age at onset of disability (greater age; higher risk), and bed disability days in the month before the baseline survey (more disability days; higher risk). Among those hospitalized, the total number of days hospitalized is significantly related to both age at onset of disability (later onset; more days) and baseline days hospitalized (greater number; more days). Lengths-of-stay are significantly related to two factors; age and age at onset of disability (in both cases, greater age associated with longer stays). Prior ER visits are a significant predictor of subsequent ER visits (more baseline; more subsequent); so are respondents' reported satisfaction with their participation in their medical care (lower reported satisfaction; more ER visits), organizational affiliations, and frequencies of contacts with friends or relatives. Higher levels of social interaction (i.e. organizational affiliation and more frequent social contacts) were associated with more ER visits. Prior contacts with physicians, nurse-practitioners, or physician-assistants was the most powerful predictor of subsequent outpatient contacts (more baseline; more subsequent). There were also significant relationships between subsequent contacts and respondents' assessments of their health relative to others with similar disabilities (relatively worse health; more contacts), age (greater age; more contacts), and baseline ER visits (more visits; more contacts).

Alcohol, tobacco, and cannabis use by independently living adults with major disabling conditions.

Data from an 18-month prospective study of 205 adults with major disabling conditions revealed that there is a positive but not statistically significant association (p greater than .10) between respondents' scores on a scale which measures both numbers and amounts of substances (alcohol, tobacco, and cannabis) used and bed disability days. There are also nonsignificant positive relationships between scale scores and five of six measures of utilization of medical care.

A prospective evaluation of the effect of managed care on medical care utilization among severely disabled independently living adults.

We conducted an 18-month longitudinal evaluation of a model-managed medical care program for severely disabled, independently living adults. Regression analyses using an additive model (no interaction effects) suggest that persons in the study group did not have statistically significantly different utilization experiences than members of the comparison group. Regression analyses that include interaction effects suggest that, for certain segments of the cohort, the study group's utilization experience was significantly lower than that of members of the comparison group. Persons in the study group with higher baseline emergency room (ER) utilization had significantly fewer hospital admissions (P = 0.0055). The participants with better self-assessments of health experienced significantly fewer hospital days per person (P = 0.0075) and days per person hospitalized (P = 0.0056), and persons with organizational affiliations reported significantly fewer ER visits (P = 0.0264).

'Lumping it': the hidden denominator of the medical malpractice crisis.

In a recent article, Miller has reminded us that medical malpractice litigation is not simply an economic problem which inhibits medical practice and increases health care costs. She argues that it has three broader "societal objectives": reparation, emotional vindication, and deterrence. Viewed in the broader perspective of social values, the Maine data suggest that our current approach to medical malpractice does not perform well. Significant numbers of respondents believe that they have been neither vindicated nor compensated for their own or their relatives' illness, injury, or death; and that they have not had the opportunity to protect others from harm. As Miller suggests in her review of British alternatives to medical malpractice litigation, there may be more efficient and effective means of reparation. There may also be more direct and less costly means to deter incompetent practitioners and vindicate those who are harmed. We shall never discover these alternatives if we view the medical malpractice "crisis" as a simple or straightforward problem of costs of premiums, costs of settlements, and costs of judgments; numerators. Medical malpractice litigation is the expression of deep and highly complicated problems, which cannot be solved or even significantly alleviated by false solutions motivated only by concerns of costs and cost containment. They can be addressed only by careful, thoughtful, and comprehensive analysis.

Assessing physical function in the elderly.

This article emphasizes the complexity underlying the assessment of physical function. The concept of physical function is multidimensional; individuals or groups can be assessed; the assessments can be either preintervention measures or outcome measures. Six issues of measurement are discussed: verbal report versus behavior; self-reported versus proxy-reported information; capacity versus performance; assumptions in Activities of Daily Living and Instrumental Activities of Daily Living measurement; differences between items and instruments; and the search for a summary index. Specific instruments are reviewed.

Rehospitalization and spinal cord injury: cross-sectional survey of adults living independently.

A cross-sectional survey of 96 people living independently with spinal cord injuries (SCI) in Eastern Massachusetts shows that 57% had been hospitalized at least once in the year before the survey. Sample means were 1.0 admissions and 16.0 days/person/year. Eight percent of the sample (eight persons) accounted for 22% of admissions and 59% of total hospital days. For those hospitalized, the mean was 1.7 admissions and 45.1 days/person/year. Mean length-of-stay was 34.7 days/admission. Multiple regression analysis shows that three variables appear to be independently related to increased numbers of admissions: self-assessment of health; place of residence; and age (younger respondents at higher risk). One variable is independently associated with total days of hospitalization: leaving home at least once daily (as opposed to less frequently) is associated with lower risk. There were no statistically significant relationships between either numbers of hospitalizations or total days hospitalized and ADL or IADL status, education, employment, medical insurance, household composition, gender, age at onset of disability, time since onset of disability, substance use (alcohol, cannabis, or tobacco), level of SCI lesion, or social supports.

The social epidemiology of alcohol use by urban older adults.

A sample survey of 928 Bostonians, aged sixty years or older, indicates that there are low levels of alcohol consumption: more than half report that they are abstainers; 6 percent indicate that they have two or more drinks daily. Levels of abstinence are particularly high among women, blacks, Jews, widows and widowers, the foreign-born, those with low levels of formal education, and those aged seventy-five years or older. Among social psychological variables, locus of control is most consistently associated with drinking: those who report little influence upon their futures--in terms of work, marriage, income, and leisure activities--are more likely to abstain. There is also an association with optimisim; those who are least optimistic about their prospects for work and leisure activities are most likely to abstain. Analysis of variance shows that gender, education, ethnicity, religion, age, and locus of control regarding work are independent correlates of alcohol use. The data suggest that older people drink mainly in social contexts and to facilitate social interaction.
