The impact of the prospective payment system on the treatment of hip fractures in the elderly

A review of 386 Medicare patients with hip fractures admitted to a private, suburban, teaching hospital from 1981 through 1987 revealed that since the implementation of the prospective payment system in 1984, average hospital stays declined from 17.0 days to 12.9 days (24.1%). Although the mean number of physical therapy sessions declined from 11.1 to 9.8 (11.7%), the average number of treatments per day during the physical therapy phase actually increased from 1.2 before to 1.4 after the prospective payment system. The proportion of patients discharged to nursing homes remained the same (52.9% vs 53.6%); the proportion of patients remaining in a nursing home 6 months after hospital discharge did not differ significantly (22.6% vs 19.9%). Furthermore, there were no differences in the 6-month ambulation status. Total adjusted average hospital charges for the pre- and post-prospective payment system groups did not increase significantly ($7295 vs $7565). These findings do not support the contention that the quality of care provided Medicare patients with hip fractures has deteriorated in this hospital environment.     

The cost of institutional care in Alzheimer's disease: nursing home and hospital use in a prospective cohort.

OBJECTIVE: To assess the nursing home and hospital use of patients with Alzheimer's Type Dementia. DESIGN: A prospective cohort study of 126 patients entered into an Alzheimer's disease registry after diagnosis at a university hospital clinic between 1980 and 1982. Only four patients were in nursing homes at enrollment. MEASUREMENTS AND MAIN RESULTS: Data regarding nursing home use came from the registry and the individual nursing homes themselves. Hospital-use data were obtained using Medicare claims files. Follow-up was obtained on 123 patients (98%). Eighty-five (69%) had died by July 1, 1989. Three-quarters of the cohort (92) eventually resided in nursing homes. The median nursing home length of stay was 2.75 years (mean 2.95, 95% CI = 2.5, 3.4), over 10 times the national median length of stay for all diagnoses. Based on prevailing rates in the region, nursing home charges for the cohort were estimated to be between $4.3 and $6.4 million ($35,000-$52,000 per patient). During the 5-year period 1983-1988, 69 patients filed Part A (hospital) claims to Medicare for 76 admissions and 616 inpatient days. Part A Medicare reimbursement for the cohort totaled $460,000 over 5 years ($3,700 per patient), an expenditure comparable to what a random Medicare cohort might incur. CONCLUSIONS: The combination of a high rate of nursing home entry and lengthy stays makes long-term care the largest determinant of the cost of care in Alzheimer's disease. While Alzheimer's Type Dementia undoubtedly has profound indirect costs, this study demonstrates that the direct institutional costs alone are considerable.     

Efficacy of a comprehensive geriatric intervention in older patients hospitalized for hip fracture: a randomized, controlled trial

OBJECTIVES: To evaluate whether an early multidisciplinary geriatric intervention in elderly patients with hip fracture reduced length of stay, morbidity, and mortality and improved functional evolution. DESIGN: Randomized, controlled intervention trial. SETTING: Orthopedic ward in a university hospital. PARTICIPANTS: Three hundred nineteen patients aged 65 and older hospitalized for hip fracture surgery. INTERVENTION: Participants were randomly assigned to a daily multidisciplinary geriatric intervention (n=155) or usual care (n=164) during hospitalization in the acute phase of hip fracture. MEASUREMENTS: Primary endpoints were in-hospital length of stay and incidence of death or major medical complications. Secondary endpoints were the rate of recovery of previous activities of daily living and ambulation ability at 3, 6, and 12 months. RESULTS: Median length of stay was 16 days in the geriatric intervention group and 18 days in the usual care group (P=.06). Patients assigned to the geriatric intervention showed a lower in-hospital mortality (0.6% vs 5.8%, P=.03) and major medical complications rate (45.2% vs 61.7%, P=.003). After adjustment for confounding variables, geriatric intervention was associated with a 45% lower probability of death or major complications (95% confidence interval=7-68%). More patients in the geriatric intervention group achieved a partial recovery at 3 months (57% vs 44%, P=.03), but there were no differences between the groups at 6 and 12 months. CONCLUSION: Early multidisciplinary daily geriatric care reduces in-hospital mortality and medical complications in elderly patients with hip fracture, but there is not a significant effect on length of hospital stay or long-term functional recovery.     

Mortality following hip fracture before and after implementation of the prospective payment system

Recent studies of patients with hip fractures from two hospitals have suggested that the marked reduction in length of stay that occurred following implementation of the Medicare prospective payment system (PPS) resulted in decreased quality of care for these patients. To assess whether this change influenced mortality, we studied patients with hip fractures aged 65 years or older from a 20% sample of Michigan Medicare enrollees. There were 2130 such patients in the 2 years preceding (October 1981 through September 1983) and 2238 in the 2 years following (October 1984 through September 1986) implementation of PPS. Although the demographic characteristics of patients with hip fractures did not change after PPS, the mean length of stay (95% confidence interval) decreased by 4.4 (4.1 to 4.7) days. However, mortality in the year following the fracture did not change: 23.2% before PPS, 23.7% after PPS; rate difference of 0.5% (-2.0 to 3.0). This finding was consistently present within subgroups defined by patient demographic characteristics. Furthermore, when the analysis was restricted to patients treated in those hospitals with the greatest reduction in average length of stay following PPS (7.5 days, or 35%), there was no significant change in 1-year mortality. For those patients who were enrolled in Medicaid and not in a nursing home at the time of the fracture, there was no increase in the rate of nursing home residence 1 year after the fracture. Thus, the findings of this population-based study suggest that the key outcomes of postfracture mortality and nursing home residence were not affected by the implementation of PPS.     

Outcomes and charges of elderly patients with acute myeloid leukemia

A retrospective database analysis was conducted to evaluate hospitalization outcomes and charges among elderly acute myeloid leukemia (AML) patients. The data source was a longitudinal (2000-2003) inpatient database from 28 US hospitals. Data on 275 AML patients aged 60 and older were analyzed for demographic and treatment characteristics, hospital mortality, length of stay (LOS), overall days of stay (DOS), and charges across multiple admissions. Multivariate modeling was performed to determine factors that influenced outcomes. Overall, 115 (41.8%) patients received inpatient chemotherapy (CT); most (90.4%) received it on the first admission. Of all initial CT regimens 40.9% consisted of a single agent. The mean LOS for initial hospitalization was 23.0 (SD 21.8) days for patients who received CT and 6.7 (SD 7.5) days for those who did not. One quarter (25.3%) of initial hospitalizations resulted in death. On initial hospitalization, mean total charges were $113,118 (SD $220,417) for patients who received CT and $43,999 (SD $190,533) for those who did not; for both groups mean charges were higher than respective subsequent admission charges. Overall, in-hospital mortality did not differ significantly between on-CT and off-CT groups (43.5 and 38.8%, respectively). In multivariate modeling, CT was significantly associated (P < 0.0001) with increased charges and LOS. Elderly patients with AML incurred substantial hospital charges and inpatient mortality. The highest charges and a substantial number of deaths occurred during first admission. Although treatment with CT was associated with increased charges and days in-hospital, inpatient mortality in the two groups was found to be similar.     

Effect of an inpatient geriatric consultation team on functional outcome, mortality, institutionalization, and readmission rate in older adults with hip fracture: a controlled trial

OBJECTIVES: To evaluate the effect of an inpatient geriatric consultation team (IGCT) on end points of interest in people with hip fracture: length of stay, functional status, mortality, new nursing home admission, and hospital readmission. DESIGN: Controlled trial based on assignment by convenience. SETTING: Trauma ward in a university hospital. PARTICIPANTS: One hundred seventy‐one people with hip fracture aged 65 and older. INTERVENTION: Participants were assigned to a multidisciplinary geriatric intervention (n=94) or usual care (n=77) during hospitalization after hip fracture. MEASUREMENTS: End points were functional status, length of stay, mortality, new nursing home admission, and hospital readmission 6 weeks, 4 months, and 12 months after surgery. RESULTS: Mean length of stay was 11.1 ± 5.1 days in the intervention group and 12.4 ± 8.5 days in the control groups (P=.24). Complete adherence to IGCT recommendations was 56.8%. A significant benefit of intervention on functional status in univariate analyses (P=.02) 8 days after surgery disappeared in a linear mixed model. Participants with dementia had better functional status in a linear mixed model than those without (P=.03), but this effect was no longer significant after Bonferroni correction for multiple testing. After 6 weeks, 4 months, and 12 months, no between‐group differences could be documented for mortality, new nursing home admission, or readmission rate. CONCLUSION: This trial could not document functional benefits of an IGCT intervention in people with hip fracture. More research is needed to investigate whether a more‐intensive approach with more‐direct control over patient management, more‐specific recommendations, and more‐intense education would be effective.     

Relation between length of hospital stay and costs of care for patients with community-acquired pneumonia

PURPOSE: Patients with pneumonia often remain hospitalized after becoming clinically stable, without demonstrated benefits on outcome. The purposes of this study were to assess the relation between length of hospital stay and daily medical care costs and to estimate the potential cost savings associated with a reduced length of stay for patients with pneumonia. SUBJECTS AND METHODS: As part of a prospective study of adults hospitalized with community-acquired pneumonia at a community hospital and two university teaching hospitals, daily medical care costs were estimated by multiplying individual charges by department-specific cost-to-charge ratios obtained from each hospital's Medicare cost reports. RESULTS: The median total cost of hospitalization for all 982 inpatients was $5, 942, with a median daily cost of $836, including $491 (59%) for room and $345 (41%) for non-room costs. Average daily non-room costs were 282% greater on the first hospital day, 59% greater on the second day, and 19% greater on the third day than the average daily cost throughout the hospitalization (all P <0.05), and were 14% to 72% lower on the last 3 days of hospitalization. Average daily room costs remained relatively constant throughout the hospital stay, with the exception of the day of discharge. A projected mean savings of $680 was associated with a 1-day reduction in length of stay. CONCLUSIONS: Despite institutional differences in total costs, patterns of daily resource use throughout hospitalization were similar at all institutions. A 1-day reduction in length of stay might yield substantial cost-savings.     

Percutaneous aortic balloon valvuloplasty in octogenarians: morbidity and mortality

STUDY OBJECTIVE: To examine the morbidity, mortality, and hospital course of an elderly patient sample (mean age, 86 years; 95% CI, 84 to 87) having percutaneous aortic balloon valvuloplasty. DESIGN: Retrospective consecutive case series before and after balloon valvuloplasty. SETTING: Tertiary care referral hospital. PATIENTS: Consecutive sample of 26 patients aged 80 years or older with symptomatic aortic stenosis referred for balloon valvuloplasty from July 1987 to July 1988. MEASUREMENTS AND MAIN RESULTS: Percutaneous aortic balloon valvuloplasty reduced the transvalvular gradient from 59 (95% CI, 51 to 67) to 31 mm Hg (95% CI, 26 to 35; P less than 0.0001) and increased aortic valve area from 0.45 (95% CI, 0.38 to 0.51) to 0.67 cm2 (95% CI, 0.58 to 0.76; P less than 0.0001). The mean length of hospital stay for the entire study population was 11.2 days (95% CI, 7.3 to 15.2) at a total hospital charge per patient of $29,600 (95% CI, 21,050 to 38,150). For patients having procedural complications (11 complications in 8 patients), surgical procedures, or cardiogenic shock, the mean hospital stay increased to 16.2 days (95% CI, 6.2 to 26.2; P less than 0.05) and the hospital charge increased to $44,400 (95% CI, 24,280 to 64,520; P less than 0.01). Two patients who presented with cardiogenic shock died, and 1 patient had an aortic valve replacement before discharge. Four patients were recently discharged (less than 1 month) and follow-up was obtained in the remaining 19 patients at 6.1 months (95% CI, 4.1 to 8.1). Five more patients, including the remaining patient who presented with cardiogenic shock, died after discharge for an overall mortality of 32%. Twelve of the remaining fourteen patients had fewer symptoms and improved an average of 1.1 New York Heart Association classes (95% CI, 0.7 to 1.4; P less than 0.0001). CONCLUSIONS: Percutaneous aortic balloon valvuloplasty in patients 80 years and older improves hemodynamics and symptoms of heart failure during short-term follow-up in most patients, but overall mortality is high in this elderly patient population. Hospital charges and length of stay were much higher in patients with complications or coexisting medical illnesses. Valvuloplasty is a reasonable alternative treatment for patients with aortic stenosis who require palliative treatment of symptoms and have high surgical risk.     

Time to ambulation after hip fracture surgery: relation to hospitalization outcomes

OBJECTIVE: To test the hypothesis: Time to ambulation (walking) after hip fracture surgery impacts the frequency of postoperative complications and length of hospital stay. METHODS: A retrospective observational study of a cohort of all patients admitted to a university teaching hospital with a principal International Classification of Diseases-9 diagnosis of a hip fracture during 3 calendar years. RESULTS: A total of 131 participants were identified (68% were aged 65 years or older). Overall, the mean time to writing an order to ambulate a patient after a hip fracture surgery was 2 +/- 1.5 days. Time to ambulation after hip fracture surgery was significantly less in patients cared for on orthopedic surgery service compared to general surgery service (1.8 +/- 1 vs 2.5 +/- 2, p <.05) or general internal medicine service (2.5 +/- 1.5, p <.05). It did not relate, however, to patient's age, sex, or race, or to patient's functional status prior to admission, fracture site (femoral neck, intertrochanteric, or subtrochanteric), whether a femoral neck fracture is displaced or not, type of anesthesia (spinal/epidural vs general), type of surgery (open reduction and internal fixation vs hemiarthroplasty), degree of preoperative risk, number of medical conditions, or to obtaining physical therapy and/or medical consultation. Time to ambulation after surgery was an independent predictor for the development of pneumonia (1.5 OR [odds ratio]/day, p <.001), new onset delirium (1.7 OR/day, p <.001), and to prolonged length of hospital stay (B [slope coefficient] = 1.36, p <.0001) but not to the development of pressure ulcers, deep venous thrombosis, or urinary tract infection. CONCLUSIONS: Delayed ambulation after hip fracture surgery is related to the development of new onset delirium and pneumonia postoperatively as well as to increased length of hospital stay. Early ambulation after hip fracture surgery should be encouraged.     

Impact of prospective payment and discharge location on the outcome of hip fracture

OBJECTIVE: To determine the impact of prospective payment by diagnosis-related groups (DRGs) on length of stay in the hospital, ambulatory status, and level of post-hospital care needed for patients hospitalized with hip fracture. DESIGN: Retrospective chart review of a consecutive series of cases before and after the reference date of implementation of the prospective payment system (PPS). SETTING: Academic, tertiary-care hospital. PATIENTS/PARTICIPANTS: 181 patients 69 years of age or older admitted with International Classification of Diseases (ICD) or DRG codes for hip fracture. RESULTS: Length of stay was shorter by 1.37 days in the post-PPS era (p = 0.05). Poorer discharge ambulation was found in the post-PPS group (p = 0.089). At one year, differences in ambulation and nursing home residence were found to be related not to the implementation of PPS, but rather to the nursing home to which the patient was discharged. Patients discharged to a facility with active physical rehabilitation were less likely to remain institutionalized (p = 0.0025) than those in "ordinary" nursing homes and ambulated more independently (p = 0.05). CONCLUSIONS: The PPS did not have a significant long-term impact on hip fracture outcome. Post-hospital care may be of crucial importance to the future quality of life of hip fracture patients.     

Impact of osteoarthritis on rehabilitation for persons with hip fracture

OBJECTIVE: To determine the impact of osteoarthritis (OA) on length of rehabilitation stay, Functional Independence Measure (FIM Instrument) ratings at discharge and followup, functional gain, and percentage of patients discharged home. METHODS: We conducted a retrospective cohort analysis using a national registry of US medical rehabilitation inpatients. We obtained standardized data for all patients admitted after a hip fracture between 1994 and 2001. Our primary analytical method was multiple regression analysis. Outcome variables were length of stay, FIM Instrument ratings at discharge and followup, functional gain, and percentage of patients discharged home. The predictor variable was the presence of OA. Covariates were age, sex, race/ethnicity, other comorbidity, admission FIM ratings, total hip replacement, and time to followup. RESULTS: We studied 1,953 patients with OA and 11,441 patients without OA admitted to inpatient rehabilitation facilities after hip fracture. Mean +/- SD length of stay for patients with OA was 18.1 +/- 10.0 days versus 16.5 +/- 8.9 days for those without OA (P < 0.01). After adjusting for age, sex, race/ethnicity, comorbidity, admission FIM ratings, and total hip replacement, OA was associated with a longer rehabilitation stay (1.4 days; P < 0.01) and slightly higher discharge FIM ratings; however, OA was not associated with lower weekly rehabilitation gain, followup FIM ratings, and percentage discharged home. CONCLUSION: Persons with hip fracture and OA had longer inpatient rehabilitation length of stay than persons without OA, but there were similarities in weekly rehabilitation gain and percentage discharged home.     

Coronary angioplasty under the prospective payment system: the need for a severity-adjusted payment scheme

To evaluate the adequacy of Diagnosis Related Group prospective payment for percutaneous transluminal coronary angioplasty, the clinical characteristics, length of stay and hospital charges of all patients undergoing this procedure at Boston's Beth Israel Hospital during a 100 day period were examined. Of 113 such patients, the 61 patients in whom nonelective dilation was performed for unstable or postinfarction angina had a significantly greater length of stay and total hospital charge (10 +/- 6 days and $14,700 +/- $7,400, respectively) than did the 52 patients in whom elective dilation was performed (6 +/- 5 days and $8,500 +/- $7,700, respectively, p less than 0.0001). Under the current prospective payment system, however, these two groups of patients would have been placed in the same Diagnosis Related Group, and would have thus commanded equal institutional reimbursement. One potential revision of the payment system is presented to help to deal with this disparity.     

A short comprehensive assessment to predict outcome of elderly patients after hip fracture

BACKGROUND AND AIMS: Hip fractures result in significant functional impairment and a high rate of institutionalization. The aim of our study was to evaluate in patients with a recent hip fracture the contribution of a short (15-min) comprehensive assessment to predict the length of stay and the risk of discharge to a nursing home. METHODS: Prospective clinical study conducted in a rehabilitation ward of the Geriatric Hospital. Functional assessment included basic activities of daily living (BADL), cognitive status (MMSE) and a 4-item geriatric depression scale (Mini-GDS). Information on demographic data, living situation, diagnosis and illness burden was also collected. RESULTS: The mean age of the 86 patients (67W/19M) was 84.2 +/- 6.8 years. In a multiple regression analysis, the length of stay in a geriatric hospital was significantly associated with both marital status (living alone) (p = 0.035) and the intervention of a caregiver on a regular basis (p = 0.036), but not with Charlson's comorbidity score. In a logistic regression model, adjusted for age, gender, marital status, intervention of a caregiver on a regular basis, BADL, Mini-GDS and Charlson's comorbidity score, the only independent predictor of nursing home admission was a MMSE < 24, which increased by 10.7-fold (2.2-50.9) the risk of being admitted to a nursing home (p = 0.003). CONCLUSIONS: A short comprehensive assessment completed a few days after a hip fracture is useful in predicting length of stay and risk of nursing home admission.     

The impact of cognitive impairment on short-term outcomes of hip fracture patients

The purpose of this study is to examine the differences in outcomes related to recovery after hip fracture among patients with and without cognitive impairment. This is a prospective cohort study of consecutively hospitalized elderly patients with acute hip fracture in a setting utilizing a multidisciplinary hip fracture service. Of the 48 patients admitted with hip fracture, 18 patients were found to have cognitive impairment postoperatively as determined by a Mini-Mental State Examination (MMSE) score 相似文献   

Health and economic outcomes of the emergence of third-generation cephalosporin resistance in Enterobacter species.

BACKGROUND: This study evaluated the clinical and economic impact of the emergence of third-generation cephalosporin-resistant Enterobacter species. METHODS: Mortality, length of hospitalization, and hospital charges were examined in a cohort that was selected from a group of 477 patients with initial cultures that yielded a third-generation cephalosporin-susceptible Enterobacter species. Case patients (n = 46) had subsequent cultures yielding a third-generation cephalosporin-resistant Enterobacter species. Control patients (n = 113) who did not develop resistance were matched to cases on site of Enterobacter infection and length of hospitalization prior to isolation of the initial susceptible organism. Multivariable analyses were used to adjust for confounding. RESULTS: Twenty-six percent of cases died vs 13% of controls (P =.06). The median total hospital stay for cases was 29.5 days (interquartile range [IQR], 20-60) and 19 days for controls (IQR, 13-27; P<.001). The median hospital charge for cases was $79 323 (IQR, $34 546-$161 384) and for controls was $40 406 (IQR, $18 470-$79 005; P<.001). After adjusting for comorbidities, severity of illness, intensive care unit admission, surgery, transfer from another hospital, sex, and age, emergence of resistance was associated with increased mortality (relative risk, 5.02; P =.01), hospital stay (1.5-fold, P<.001), and hospital charges (1.5-fold, P<.001). Emergence of resistance had a median attributable hospital stay of 9 days and an average attributable hospital charge of $29 379. CONCLUSIONS: Emergence of antibiotic resistance in Enterobacter species results in increased mortality, hospital stay, and hospital charges. Minimizing resistance in Enterobacter species should be a priority.     

Factors associated with a protracted hospital stay after hip fracture surgery in Japan

Aim: Hip fracture is a major injury in the elderly and has a high impact on quality of life and use of health‐care resources. In this study, we aimed to identify the factors related to prolonged hospital stay and poor outcome after hip fracture surgery. Methods: We evaluated data from 8920 cases at 398 acute‐care hospitals in Japan. Multivariate logistic regression analysis was used to determine the factors associated with the length of postoperative hospital stay. Results: A shorter postoperative hospital stay was associated with admission to a high surgical volume hospital (P < 0.001). On the other hand, a longer postoperative hospital stay was associated with infective complications, admission to a private hospital, an interval of more than 3 days between admission and surgery (P < 0.001 for all), and an interval of more than 1 day between surgery and start of rehabilitation (P = 0.01). Further analysis revealed that infective complications were more likely in older patients (P = 0.003) and patients with comorbidities (P = 0.03). Conclusion: The results imply that hospital stay, and, therefore, use of medical resources, can be decreased by performing surgeries shortly after patients are admitted, preventing postoperative infections, and starting rehabilitation on the next day of the surgery. One of the limitations of our study was that data of the length of hospital stay at transferred hospitals were not available. Therefore, further prospective studies will be needed to address significance of early surgery and rehabilitation. Geriatr Gerontol Int 2011; 11: 474–481.     

Impact of troponin T determinations on hospital resource utilization and costs in the evaluation of patients with suspected myocardial ischemia

The evaluation and triage of patients with suspected myocardial ischemia in the emergency department remains challenging and costly. Previous studies of cardiac troponins have focused predominantly on patients with chest pain and have not randomized patients to different diagnostic strategies. Eight hundred fifty-six patients with suspected myocardial ischemia were prospectively randomized to receive a standard evaluation, including serial electrocardiographic and creatine phosphokinase-MB determinations (controls) or a standard evaluation with the addition of serial troponin T determinations (troponin group). The primary end points were length of stay and hospital charges. Significant reductions in length of hospital stay were seen in troponin T patients both with (3.6 vs 4.7 days; p = 0.01) and without (1.2 vs 1.6 days; p = 0.03) acute coronary syndromes compared with controls. Total hospital charges were reduced in a similar fashion in troponin patients with and without acute coronary syndromes ($15,004 vs $19,202; p = 0.01, and $4,487 vs $6,187; p = 0.17, respectively) compared with controls. Troponin patients without acute coronary syndromes had fewer hospital admissions (25% vs 31%; p = 0.04), whereas troponin patients with acute coronary syndromes had shorter telemetry and coronary care unit lengths of stay (3.5 vs 4.5 days; p = 0.03) compared with controls. Thus, utilization of troponin T in a broad spectrum of emergency department patients with suspected myocardial ischemia improves hospital resource utilization and reduces costs.     

Laparoscopic colectomy vs. open colectomy for sigmoid diverticular disease

PURPOSE: The feasibility of laparoscopic colectomy for colon surgery has now been well established. Most of the studies on laparoscopic colectomies include all types of colonic pathologies without discrimination. Our goal was to compare laparoscopic sigmoid colectomy open sigmoid colectomy for simple sigmoid diverticular disease, to assess whether it can be done safely and whether the proposed advantages could be realized. METHODS: We evaluated the differences in outcomes of 66 laparoscopic sigmoid colectomy patients and 88 open sigmoid colectomy patients. We report a five-year outcomes analysis of 154 patients undergoing sigmoid colectomy for diverticular disease. We compared age, gender, history of prior abdominal surgery, estimated blood loss, operative time, total conversions with reason for conversion, time until a liquid diet was started, postoperative complications, hospital length of stay, operation costs, and total hospital charges incurred for both laparoscopic sigmoid colectomy and open sigmoid colectomy. RESULTS: Mean age and gender were similar in the two groups. However, the mean estimated blood loss (143 ml 314 ml), time until a liquid diet was started (2.9 4.9 days), and hospital length of stay (4.8 8.8 days) were all significantly less in laparoscopic sigmoid colectomy patients. The mean operative time for laparoscopic sigmoid colectomy was 212 minutes as compared with 143 minutes for open sigmoid colectomy ( < 0.05). Conversion rate of laparoscopic sigmoid colectomy to open procedure was 19.7 percent. All laparoscopic sigmoid colectomy patients received a lighted ureteral stent preoperatively, which was removed at the end of surgery. Relevant complications for laparoscopic sigmoid colectomy open sigmoid colectomy were as follows: anastomotic leak in 1 3 (1.5 3.4 percent) patients, hematuria in 64 6 (97 6.8 percent) patients, with an average duration for 2.93 3 days, urinary tract infection in 5 4 (7.6 4.5 percent) patients, and ureteral injury in 1 2 (1.5 2.2 percent) patients. Although the mean operating room charges were greater in the laparoscopic sigmoid colectomy patients ($9,566 $7,306) the mean hospital charges ($13,953 $14,863) were less. CONCLUSIONS: We recommend laparoscopic sigmoid colectomy as the modality of treatment for diverticular disease. Laparoscopic sigmoid colectomy seems to be a reliable, safe and efficacious treatment modality with better outcomes for diverticular disease of the sigmoid colon. The operative time for laparoscopic sigmoid colectomy is decreasing as surgeons gain more experience.     

A randomized trial of comprehensive geriatric assessment and home intervention in the care of hospitalized patients

OBJECTIVE: to prove the effectiveness of geriatric evaluation and management for elderly, hospitalized patients, combined with post-discharge home intervention by an interdisciplinary team. DESIGN: randomized controlled trial with outcome and costs assessed for 12 months after the date of admission. SETTING: university-affiliated geriatric hospital and the homes of elderly patients. SUBJECTS: 545 patients with acute illnesses admitted from home to the geriatric hospital. INTERVENTIONS: patients were randomly assigned to receive either comprehensive geriatric assessment and post-discharge home intervention (intervention), comprehensive geriatric assessment alone (assessment) or usual care. MAIN OUTCOME MEASURES: survival, functional status, rehospitalization, nursing home placement and direct costs over 12 months. RESULTS: the intervention group showed a significant reduction in length of hospital stay (33.49 days vs 40.7 days in the assessment group and 42.7 days in the control group; P < 0.05) and rate of immediate nursing home placement (4.4% vs 7.3% and 8.1%; P < 0.05). There was no difference in survival, acute care hospital readmissions or new admissions to nursing homes but the intervention group had significantly shorter hospital readmissions (22.2 days vs 34.2 days and 35.7 days; P < 0.05) and nursing home placements (114.7 days vs 161.6 days and 170.0 days; P < 0.05). Direct costs were lower in the intervention group [about DM 7000 (US $4000) per person per year]. Functional capacities were significantly better in the intervention group. CONCLUSIONS: comprehensive geriatric assessment in combination with post-discharge home intervention does not improve survival, but does improve functional status and can reduce the length of the initial hospital stay and of subsequent readmissions. It can reduce the rate of immediate nursing home admissions and delay permanent nursing home placement. It may also substantially reduce direct costs of hospitalized patients.     

The effectiveness of implementing a care pathway for femoral neck fracture in older people: a prospective controlled before and after study

OBJECTIVES: To investigate whether a care pathway for older hip fracture patients can reduce length of stay while maintaining the quality of clinical care. DESIGN: Prospective study of patients admitted 12 months before and after implementation of a care pathway for the management of femoral neck fracture. Audit data for corresponding time periods from nearby orthopaedic units was used to control for secular trends. SETTING: Teaching hospital. SUBJECTS: Patients aged 65 years and over with a femoral neck fracture. Exclusion criteria: multiple fractures, fractures due to malignancy, re-fracture, total hip replacement, previously entered into the study, operation performed elsewhere. Three-hundred and ninety-five (99%) and 369 (97%) case records were available for full analysis. Main outcome measures: primary outcome: length of stay on the orthopaedic unit. Secondary outcomes: ambulation at discharge, discharge destination, in-hospital complications, 30 day mortality, readmission within 30 days of discharge, post-operative days the patient first sat out of bed and walked. RESULTS: Mean length of stay increased by 6.5 days (95% confidence interval 3.5-9.5 days, P < 0.0005) in the second period with a significant improvement in ambulation on discharge (odds ratio 1.6, 95% confidence interval 1.0-2.6, P = 0.033) and a trend towards reduction in admission to long term care (odds ratio 0.6, 95% confidence interval 0.3-1.0, P = 0.058). CONCLUSIONS: This care pathway was associated with longer hospital stay and improved clinical outcomes. Care pathways for hip fracture patients can be a useful tool for raising care standards but may require additional resources.
