Repeat EMS transports among elderly emergency department patients.

OBJECTIVES: Previous studies of repeat care of the elderly have focused on trauma cases only. The purposes of this study were to identify repeat transports of elderly patients to the authors' emergency department (ED) by emergency medical services (EMS), to identify demographics, and to compare chief complaints. METHODS: A population-based, retrospective cohort study was conducted. Data for this study were obtained from computerized registration files in an urban, university-affiliated ED with an annual census of approximately 60,000 visits. Patients were included if they were 65 years of age or older and they were transported by EMS in 1997. The repeater group included patients who had one or more EMS transports within the following 12 months. The comparison group was composed of all patients with no further EMS transport within the 12 months after the index visit. Demographics extracted from the database were gender, chief complaint, total number of visits, and time since previous visits. Repeats were characterized by frequency (number of visits in 12 months after the index visit), type (visit for same vs different complaint), and rate (time to the first return visit). Repeaters were defined as more than one visit within a 12-month period. Repeaters were subdivided as follows: "immediate" (within 72 hours), "short-term" (within 2 months), and "long-term" (within 12 months). Chi-square and 95% confidence intervals (95% CIs) were used. A p-value < 0.05 was considered statistically significant. RESULTS: There were 365 (23%) repeaters and 1,212 (77%) nonrepeaters. Repeaters accounted for 811 (40%) of the total of 2,023 elderly patients transported by EMS. Fifty-seven percent of all elderly patients transported by EMS were female, with no significant difference between the repeaters and nonrepeaters. There were significantly fewer transports for a chief complaint of trauma among the repeaters than among the nonrepeaters (14% vs 26%, diff = 12, 95% CI = 9-15%). Among the 365 repeaters, 186 (51%) had two transports, 92 (15%) had three transports, 36 (10%) had four transports, and 51 (14%) had five or more transports. Of the return transports by repeaters, 40 (12%) were "immediate," 191 (52%) were "short-term," and 134 (36%) were "long-term." CONCLUSION: Repeaters accounted for 18% of elderly ED patients transported by EMS and 40% of elderly transports to the authors' ED. There were significantly fewer trauma transports in the repeater group. One-half of the repeaters returned only once in a 12-month period and a third of these occurred more than three months apart. It is important to understand the characteristics of elderly EMS repeaters in order to use this opportunity for intervention.

Emergency medical services screening of elderly falls in the home.

OBJECTIVES: Previous studies of injury prevention among the elderly have focused on care by community-based services for the elderly. The plan for this study was to determine whether emergency medical services (EMS) could be a valuable partner in an injury prevention program for the elderly. The purposes of the study were: 1) to determine whether it is feasible to gather injury prevention data prospectively, 2) to determine whether these data suggest the need for further intervention to aid the elderly, and 3) to determine whether retrospective chart data are comparable to prospectively gathered data for evaluating the elderly home environment. METHODS: Trained fire/EMS chiefs gathered prospective data from the homes of all elderly falls. Patients were included if they were 65 years of age or older. Demographics extracted from the chart were gender, age, and average income based on zip code information from the city office. A 29-question survey was developed based on a literature review. Results were obtained representing information in six categories: environment, appearance, health, violence, access to help, and repeat medical care utilization. Retrospective data were obtained from run reports and from a computerized EMS database. Proportions and 95% confidence intervals were used. A p-value < 0.05 was considered statistically significant. RESULTS: There were 70 prospective elderly fall cases evaluated and 74 retrospective charts reviewed, each representing a two-to-four-month period. Prospectively, significant problems were found with the patient's environment in up to 53% of cases, appearance in up to 29%, health in up to 77%, abuse in up to 3%, access in up to 57%, and repeat use in 33-68%. Although there were no differences in the age, income, or percentage transported between the prospective and retrospectively obtained groups, a significantly higher percentage of females were entered prospectively. Retrospective chart review obtained reasonable amounts of data for only four of 29 questions. CONCLUSION: Prospective analysis is easily gathered and identifies elderly injuries and patterns. A significant number of elderly patients whose homes were visited by EMS need help. Retrospective analysis gleans little injury prevention information.

Relationship of restraint use, patient injury, and assaults on EMS personnel.

OBJECTIVE: We hypothesized that the assaults on EMS personnel by patients requiring restraints can be correlated with demographic information, patient condition, and other scene information such as presence the of law enforcement. METHODS: The study was a one-year cross-sectional study of paramedic restraint use and assault on EMS personnel in an urban area. A data collection form was completed by EMS for each patient placed in restraints. Study outcome variable was "Assault on EMS personnel." Predictor variables included demographic and EMS call information, patient condition, law-enforcement related variables, and the paramedic's perception of the need for chemical restraints. To compare predictor and outcome variables, a multivariable model with odds ratios and 95% confidence intervals was used. RESULTS: The study included 271 restrained patients over a 12-month period from April 2002 to April 2003. Seventy-seven (28%) cases were positive for assaults on EMS personnel. Multivariable analysis including 8 variables, indicated the following 6 variables were associated with assault on EMS personnel: time of day between midnight and 6 am (OR = 4.4, 95% CI = 1.6-12.7); female patient (OR for males 0.6, 95% CI = 0.3-1.0); violent patient (OR = 10.1, 95%CI = 2.3-48.2); patient injured under supervision (OR = 3.9, 95% CI = 1.1-13.8); arrested patient (OR = 4.4, 95% CI = 1.1-18.5); and perceived need for chemical restraint (OR = 2.1, 95% CI = 1.2-3.9). CONCLUSION: Multiple factors are correlated with assaults on EMS personnel by patients requiring restraints. By specifically targeting patients exhibiting these factors, EMS providers can help prevent injury to themselves. Patients not exhibiting these factors may be less dangerous.
