Length of stay in hospital following spinal cord lesions in Israel.

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: To monitor length of stay (LOS) in a specialist spinal cord lesion (SCL) department in Israel, evaluate factors that affect it, and assess its association with other outcome measures. SETTING: Loewenstein Rehabilitation Hospital, Raanana, Israel. METHODS: In all, 1367 SCL patients treated between 1962 and 2000, and a group of 44 patients admitted between 1996 and 2002 were recruited. LOS, factors that affect it, and Spinal Cord Independence Measure second version (SCIM-II) gain and efficiency were measured. Data were collected from hospital charts and from the Population Registry of the Israel Ministry of Internal Affairs. LOS associations were analyzed with ANOVA, ANCOVA, Pearson's chi(2) test, Pearson's correlation, and Cox proportional hazard model. RESULTS: The mean LOS was 239 days for traumatic SCL (SD=168) and 106 days for non-traumatic SCL (SD=137). SCL etiology, SCL severity, and decade of admission to rehabilitation, were associated with the LOS (P<0.001). SCIM II gain correlated with LOS in the first 70 days after admission (r=0.81-0.82; P<0.001). In some patients, longer LOS was associated with a considerable increase in ability, through 5-8 months from admission. CONCLUSIONS: LOS of patients with SCL in Israel is within the customary LOS range in Europe. Longer LOS in a specialist SCL department may be positively associated with improved rehabilitation outcome. Further study is required to determine the LOS that allows optimal achievements.

Survival following spinal cord injury in Israel.

BACKGROUND: Survival following spinal cord injury (SCI) has greatly improved since the unsuccessful attempts to repair the damaged spinal cord were replaced by systematic prevention and treatment of complications caused by the neural damage. OBJECTIVE: To evaluate the main outcome measures in patients with spinal cord injury. DESIGN: Retrospective cohort study. SETTING: Loewenstein Rehabilitation Hospital, the major referral center for rehabilitation medicine for hospitals throughout Israel. SUBJECTS: 250 consecutive patients, injured between 1959 and 1992. MAIN OUTCOME MEASURES: Survival rates and mortality risk factors. METHOD: Demographic, clinical, and mortality data were collected from the hospital charts and from the Population Registry of the Israel Ministry of Internal Affairs. Survival rates were estimated using the product limit (Kaplan-Meyer) method, and their association with known risk factors was analyzed with the Cox proportional hazard model. RESULTS: The survival rate after injury was 81% after 10 years, 75% after 20 years, and 62% after 30 years, and 50% after about 36.5 years. Survival was found to be negatively associated with age (P=0.01) and with high spinal level of injury (P=0.003). CONCLUSIONS: Survival rates in the studied population are similar to those reported in other countries, and are close to those of the general population living in Israel in the same time period. The study demonstrates that developing countries can reach survival rates comparable to those of developed countries, and may contribute to better survival predictions of patients with SCI.
