RESUMEN
Background: Lengthy hospitalization may lead to an increased hospital-acquired patient complication, including infections, as well as increased costs for both healthcare systems and patients. A few studies evaluated the impact of various clinical and demographic variables on patients' length of stay (LOS). Hence, in this study, we aimed to investigate the impact of various variables on traumatic patients' LOS. Methods: This is a retrospective single-center, registry-based study of traumatic patients admitted to Taleqani, a major trauma center in Kermanshah, Iran. A Minimal Dataset (MDS) was developed to retrieve traumatic data on demographic and clinical aspects. We used univariable and multiple quantile regression models to evaluate the association between independent variables, including ISS, GCS, and SBP, with LOS. LOS is practically defined as the time interval between hospital admission and discharge. The LOS durations have been presented as median (Q1 to Q3) hours. A p-value of <0.05 was considered statistically significant. Results: A total of 2708 cases were included in this study, with 1989 (73.4%) of them being male. The median LOS was 87.00 (48.00 to 144.00) hours. When adjusted for systolic blood pressure (SBP), Glasgow Coma Scale (GCS), Injury Severity Score (ISS), and cause of injury, the two characteristics of spine/back and multiple trauma were significantly associated with the higher LOS, with 43 (20.5 to 65.48) and 24 (10.39 to 37.60) hours more than extremities (P < 0.001 and P = 0.005). Besides, the patients admitted due to road traffic injuries (RTI) were discharged 16 and 41 hours later than falling and cutting/stabbing (P = 0.008 and < 0.001, respectively). Moreover, the patients with ISS≥16 and 9≤ISS≤15 had a median of 51 (21 to 80) and 34 (22 to 45) LOS hours more, compared to 1≤ISS≤8, respectively (P < 0.001). The trauma cases experiencing SBP ≤ 90 mmhg on admission had a median of 41 (20 to 62) hours more hospitalization period than those with SBP> 90 mmhg (P < 0.001). At last, the patients with GCS of 9 to 12 and GCS of 3 to 8 were hospitalized for 39 and 266 hours more than GCS of 13 to 15 (P < 0.001). Conclusion: Determining independent determinants of prolonged LOS may lead to better identifying at-risk patients on admission. Trauma care providers should consider the following risk factors for increased LOS: higher ISS, Lower GCS, and SBP, multiple trauma or spine injury, and trauma resulting from falling or cutting/stabbing. As a result, the impact of extended LOS might be reduced by intervening in the related influencing factors.
RESUMEN
Background: Lumbar spinal stenosis (LSS) is the most common indication for lumbar surgery in elderly patients. Epidural injections of calcitonin are effective in managing LSS. Objectives: This study aimed to compare the efficacy of transforaminal and caudal injections of calcitonin in patients with LSS. Methods: In this double-blind randomized clinical trial, LSS patients were divided into two equal groups (N = 20). The first group received 50 IU (international units) of calcitonin via caudal epidural injection (CEI), and the second group received 50 IU of calcitonin via transforaminal epidural injection (TEI). The Visual Analogue Scale (VAS) and Oswestry Low Back Pain Disability Questionnaire (ODI) were used to assess the patient's pain and ability to stand, respectively. Visual Analogue Scale and ODI scores were recorded and analyzed. Results: The results showed that caudal and TEIs of calcitonin significantly improved pain and ability to stand during follow-up compared to before intervention (P < 0.05). Additionally, CEI of calcitonin after 6 months significantly reduced pain in LSS patients compared to TEI of calcitonin (P < 0.05). However, no significant difference was observed between the two epidural injection techniques in improving the patient's ability to stand (P > 0.05). Conclusions: The results of the study indicate that epidural injection of calcitonin in long-term follow-up (6 months) had a significant effect on improving pain intensity and mobility in patients with LSS, and its effect on pain in the TEI method was significantly greater than that in the CEI method.
RESUMEN
Objective: The main objective of this study was to determine various characteristics and outcomes of self-harm and suicide in men and women with data obtained from the National Trauma Registry of Iran (NTRI). Method : This retrospective multicenter study using data from the NTRI included all patients who went to the emergency department (ED) due to self-harm and suicide, considering the NTRI's specific inclusion criteria, from September 2016 to January 2023. We evaluated patients regarding demographics and clinical characteristics, various outcomes, and factors influencing in-hospital death. Statistical analyses were conducted using the STATA software version 15.0. The chi-square test was used to compare the distribution of variables between men and women. Also, the logistic regression models were applied to assess the predictors of in-hospital death. Results: Self-harm and suicide cases were gathered from eleven geographically diverse hospitals across the country, and our study included 511 men and 347 women out of 50,661 registered trauma cases. Among them, 443 men (86.7%) and 267 women (76.9%) were between 18 and 49 years old (P < 0.001). Single women constituted 130 (37.3%) of the female cases, while single men were 313 (61.6%) of the male cases (P < 0.001). The three most common methods among our patients were poisoning with 234 (45.8%) of men and 245 (70.6%) of women cases, stab/cut with 208 (40.7%) of men and 54 (15.6%) of women cases, and fall with 16 (3.1%) of men and 26 (7.5%) of women cases (P < 0.001). The risk of death in patients with a Glasgow Coma Scale (GCS) score of 3 to 8 was 46.22 (95% CI = 18.66 to 114.45) times more than patients with a GCS score of 13 to 15. Conclusion: Data on self-harm and suicide traumatology were gathered from eleven hospitals in Iran. Our findings indicated differences in the distribution of age and marital status between genders. Moreover, both genders used similar methods for self-harm and suicide, and gender did not affect the outcome.
