Clinical practice guidelines recommend a conservative approach to management of acute low back pain (LBP). The present study sought to determine whether health care utilization and the physician's initial management of work-related LBP were associated with disability duration. Clinical management information was obtained for 98 randomly selected, workers' compensation claimants with acute, uncomplicated, disabling work-related LBP. Length of disability was based on indemnity (wage replacement) payments. Disability was significantly associated with increased utilization of specialty referrals (P = 0.013) and provider visits (P < 0.001), use of magnetic resonance imaging (P = 0.003), and use of opioids for more than 7 days (P = 0.013). Effects of early diagnostic imaging (first 30 days of care) on length of disability were observed (P = 0.001). Patients whose treatment course did not involve extended opioid use and early diagnostic testing were 3.78 times more likely (95% confidence interval, 1.6 to 8.9) to have gone off disability status by the end of the study. The nature of the association between these initial clinical management aspects and LBP disability duration merits further exploration.

Military attacks which repeated on Gaza strip were contributed forced displacement, which causing displaced community to take refuge in shelters. This study was aimed to illustrate the importance and availability of logistical planning standards for responding shelters of displacement in Gaza Strip during 2014 military aggression .The descriptive analytical approach was used by distributing 60 questionnaires as a random sample of workers in centres during 2014. This study explores the importance of logistical planning standards with relative weight (88.74)%, And the availability of logistical planning standards for responding shelters centres in Gaza Strip reached (60.61%), This is a guide for spatial standards according to displace community, nature of land and infrastructure. This research was recommended strengthening logistical planning based on the proper assessment for force-displacement communities, also provide planning and designing standards for land which based on infrastructure, urban structure, social factors, enhancing participatory training, vulnerable groups and people who work together which arranged according to force displacement
