Risk Factors for Falls in Hospital In-Patients: A Prospective Nested Case Control Study.

BACKGROUND: Patient falls are considered a challenge to the patient's safety in hospitals, which, in addition to increasing the length of stay and costs, may also result in severe injuries or even the death of the patient. This study aims to investigate the associations between risk factors among fallers in comparison with the control group. METHODS: A prospective nested case control study was performed on 185 patients who fell and 1141 controls were matched with the patients at risk of fall in the same ward and during the same time. This study was conducted in a university educational hospital in Tehran with 800 beds during a 9-month period. The data included demographics, comorbidities, admission details, types of medication, clinical conditions, and activities before or during the fall. The data was collected from clinical records, hospital information system, error reporting system and observations, and the interviews with the fallers, their families and care givers (physicians, nurses, etc). Data analysis was conducted through time-based matching using a multi-level analysis. RESULTS: In a multilevel model including patient-related, medication, and care-related variables, the factors that were significantly associated with an increased risk of patient falls included: longer length of stay (odds ratio [OR] = 1.01; CI=0.32 to 0.73), using chemotherapy drugs, sedatives, anticonvulsants, benzodiazepines, and angiotensin-converting enzyme (ACE) inhibitors, visual acuity (OR=6.93; CI=4.22 to 11.38), balance condition (OR= 6.41; CI=4.51 to 9.11), manual transfer aid (OR=8.47; CI=5.65 to 12.69), urinary incontinence (OR= 8.47, CI= 5.65 to 12.69), and cancer (OR=2.86, CI=1.84-4.44). These factors were found to be associating with more odds for a falling accident among patients. Several characteristics such as fall history (OR=0.48; CI= 1.003 to 1.02), poly-pharmacy (OR=1.37, CI=00.85 to 2.2), stroke (OR=0.94, CI= 0.44 to 2.02), and nurse to patient ratio (incidence rate ratio=1.01, CI=0.01 to 0.03) were not significantly associated with falling in hospitals. CONCLUSION: It seems that a combination of both patient-related factors and history of medication should be considered. Moreover, modifiable clinical characteristics of patients such as vision improvement, provision of manual transfer aid, diabetes control, regular toilet program, and drug modification should be considered during the formulation of interventions.

Pressure Ulcer Rate in Multidisciplinary Hospital Units After Multifactorial Intervention: A Stepped-Wedge, Cluster Randomized Controlled Trial.

OBJECTIVES: This study was conducted to measure the effectiveness of interventions in decreasing the rates of pressure ulcer in a general hospital setting. METHODS: Sixteen units in a general hospitals in Iran participated in this stepped-wedge, cluster randomized controlled trial during a 45-week study period. This trial has a one-sided crossover design from control to intervention. The units were randomly assigned fulfilling entry criteria. After the approval by the governing board of hospital, the manipulative intervention, in addition to usual care, was implemented on patients with a Braden criterion of 14 or less. The primary outcome was ulcer specification (grade and location of ulcer), and the secondary outcome was the length of hospital stay. RESULTS: A total of 18,900 patients were admitted during the 45-week study period in the study units, of whom approximately 20% (3846 patients) were identified as high risk according to the items of Braden scale criteria during the admission assessment by nurses. The highest rate of PUs (80%) was in grade 2, and 16% of patients had grade 3 and 4 PUs. The ulcers of the skin overlying the sacrum and hip areas were the most common sites in the patients under study. The rates of PU in the control, training, and intervention phases were 5.49 (4.72-6.34), 5.68 (3.82-8.15), and 4.62 (3.87-5.47), respectively, per 1000 patient-days. CONCLUSIONS: The multifaceted intervention proposed by the present study has succeeded in reducing rate of pressure ulcer. Multifaceted programs based on training are appropriate ways to provide essential information to patients and their caregivers, which result in improvement of their participation in therapeutic process. We recommend hospitals to use these findings as a quality improvement plan for decreasing the rate of pressure ulcer.

The effectiveness of earmuffs on the physiologic and behavioral stability in preterm infants.

BACKGROUND: The use of earmuffs can protect preterm infants against negative effects of high noise levels in the neonatal intensive care unit. This study was aimed at assessing the effectiveness of the earmuffs on the physiologic and behavioral responses in preterm infants. METHODS: A crossed over controlled trial was conducted at Aliasghar Hospital (Tehran, Iran) in 2014. Thirty-six preterm infants cared in closed incubators, 18 cases wore a pair of silicon earmuffs in the first day and the others were worn it at the second day. During 2 consecutive days, all subjects were observed as their own controls (without earmuffs). Physiologic (body temperature, heart rate, respiratory rate, systolic, diastolic pressures, arterial Oxygen Saturation) and behavioral responses (according to the Anderson behavioral state scoring system) were assessed every 2 h for 8 h long during daytime for two consecutive days. RESULTS: The application of earmuffs could decrease the rate of the heart and respiratory while could increase the amount of oxygen saturation (p < 0.05). The results also showed that the preterm infants with earmuffs had lower ABSS score and a better light sleep compared to those without earmuffs (2.38 ± 0.47 versus 4.8 ± 0.97, p < 0.05). CONCLUSION: The results indicated that using the earmuffs reduces the level of noise in NICUs following by improving the preterm neonates' physiological stability and behavioral states of ABSS.

Effectiveness of orientation tour on children's anxiety before elective surgeries.

AIM: The purpose of this study was to investigate the effectiveness of an orientated tour in reduction of children's anxiety before elective surgeries. Anxiety is a common emotional reaction following surgical experience among children that can result in increasing postoperative pain, increasing analgesic use. METHODS: The study was a blinded clinical trial; 70 children were randomized into two groups (intervention and control). All children received standard preoperative care, while those in the intervention group also received an orientated tour with their mother of the operation room the night before the surgery was carried out. The children's anxiety was assessed by the "Child Drawing: Hospital" instrument and vital signs measured before and after intervention in both groups. Data were analyzed with SPSS ver. 11.5 software. RESULTS: Anxiety decreased in the intervention group following implementation of the orientated tour (P = 0.024). Following the orientated tour in the intervention group, respiration rate (P < 0.000) and blood pressure (P < 0.001 systolic and diastolic) were significantly reduced, while heart rate and body temperature were not significantly different to pre-intervention. Comparison changes of vital signs following the orientated tour between the two groups was not significant. CONCLUSION: Implementation of an orientated tour of the preoperative room can decrease anxiety levels in children before elective surgeries, but it has no clinical effect on vital signs.
