Psychometric properties of an instrument measuring communication within and between the professional groups licensed practical nurses and registered nurses in anaesthetic clinics.

BACKGROUND: The most common cause of clinical incidents and adverse events in relation to surgery is communication error. There is a shortage of studies on communication between registered nurses and licenced practical nurses as well as of instruments to measure their perception of communication within and between the professional groups. The aim of the present study was to evaluate the psychometric properties of the Swedish version of the adapted ICU Nurse-Physician Questionnaire, designed to also measure communication within and between two professional groups: licensed practical nurses and registered nurses. Specifically, the aim was to examine the instrument's construct validity using confirmatory factor analysis and its internal consistency using Cronbach's Alpha. METHODS: A cross-sectional and correlational design was used. The setting was anaesthetic clinics in two Swedish hospitals. A total of 316 questionnaires were delivered during spring 2011, of which 195 were analysed to evaluate the psychometric properties of the questionnaire. Construct validity was assessed using confirmatory factor analysis and internal consistency using Cronbach's Alpha. To assess items with missing values, we conducted a sensitivity analysis of two sets of data, and to assess the assumption of normally distributed data, we used Bayesian estimation. RESULTS: The results support the construct validity and internal consistency of the adapted ICU Nurse-Physician Questionnaire. Model fit indices for the confirmative factor analysis were acceptable, and estimated factor loadings were reasonable. There were no large differences between the estimated factor loadings when comparing the two samples, suggesting that items with missing values did not alter the findings. The estimated factor loadings from Bayesian estimation were very similar to the maximum likelihood results. This indicates that confirmative factor analysis using maximum likelihood produced reliable factor loadings. Regarding internal consistency, alpha values ranged from 0.72 to 0.82. CONCLUSIONS: The tests of the adapted ICU Nurse-Physician Questionnaire indicate acceptable construct validity and internal consistency, both of which need to be further tested in new settings and samples.

Lung cancer among native and foreign-born Swedes: histopathology, treatment, and survival.

BACKGROUND: Lung cancer (LC) is the leading cause of cancer-related death worldwide, including Sweden. Several studies have shown that socioeconomic status affects the risk, treatment, and survival of LC. Due to immigration after Second World War, foreign-born people constitute 12.5% of the Swedish population. We wanted to investigate if there were any differences in LC management, treatment and survival among the foreign-born Swedes (FBS) compared to the native Swedish population (NatS) in Stockholm. MATERIAL AND METHODS: A retrospective analysis of all patients diagnosed with non-small cell lung cancer (NSCLC) at the Department of Respiratory Medicine and Allergy, Karolinska University Hospital, Solna from 1 January 2003 to 31 December 2008 was made. In all, 2041 cases of LC were diagnosed, thereof 1803 with NSCLC. Of these, 211 (11.7%) were FBS. RESULTS: The mean age of NatS and FBS patients was 69.9 years, median 70 (range 26-96) and 66.0 years, median 66 (range 38-94), respectively (p < 0.001). In all, 89.8% of NatS and 90.0% of FBS were either smokers or former smokers. Adenocarcinoma was the most common subtype in both groups (NatS 54.7%, FBS 48.3%). In 140 (8.8%) of the NatS and 17 (8.1%) of the FBS the diagnosis was clinical only. There were no significant differences in stage at diagnosis, nor in performance status (PS) or different therapies between the groups. The median overall survival time for the NatS was 272 days and for FBS 328 days, again no significant difference. However, the median overall survival time for female NatS was 318 days and for female FBS 681 days (p = 0.002). CONCLUSION: FBS patients were significantly younger than NatS at diagnosis, and female FBS lived longer than female NatS, but otherwise there were no significant differences between NatS and FBS patients with LC regarding diagnosis, treatment, and survival.

Implementing situation-background-assessment-recommendation in an anaesthetic clinic and subsequent information retention among receivers: A prospective interventional study of postoperative handovers.

BACKGROUND: Communication errors cause clinical incidents and adverse events in relation to surgery. To ensure proper postoperative patient care, it is essential that personnel remember and recall information given during the handover from the operating theatre to the postanaesthesia care unit. Formalizing the handover may improve communication and aid memory, but research in this area is lacking. OBJECTIVE: The objective of this study was to evaluate whether implementing the communication tool Situation-Background-Assessment-Recommendation (SBAR) affects receivers' information retention after postoperative handover. DESIGN: A prospective intervention study with an intervention group and comparison nonintervention group, with assessments before and after the intervention. SETTING: The postanaesthesia care units of two hospitals in Sweden during 2011 and 2012. PARTICIPANTS: Staff involved in the handover between the operating theatre and the postanaesthesia care units within each hospital. INTERVENTION: Implementation of the communication tool SBAR in one hospital. MAIN OUTCOME MEASURES: The main outcome was the percentage of recalled information sequences among receivers after the handover. Data were collected using both audio-recordings and observations recorded on a study-specific protocol form. RESULTS: Preintervention, 73 handovers were observed (intervention group, n = 40; comparison group, n = 33) involving 72 personnel (intervention group, n = 40; comparison group, n = 32). Postintervention, 91 handovers were observed (intervention group, n = 44; comparison group, n = 47) involving 57 personnel (intervention group, n = 31; comparison group, n = 26). In the intervention group, the percentage of recalled information sequences by the receivers increased from 43.4% preintervention to 52.6% postintervention (P = 0.004) and the SBAR structure improved significantly (P = 0.028). In the comparison group, the corresponding figures were 51.3 and 52.6% (P = 0.725) with no difference in SBAR structure. When a linear regression generalised estimating equation model was used to account for confounding influences, we were unable to show a significant difference in the information recalled between the intervention group and the nonintervention group over time. CONCLUSION: Compared with the comparison group with no intervention, when SBAR was implemented in an anaesthetic clinic, we were unable to show any improvement in recalled information among receivers following postoperative handover.

Computer tomography-guided core biopsies in a county hospital in Sweden: Complication rate and diagnostic yield.

BACKGROUND: Core biopsies are valuable in obtaining sufficient tissue to ensure diagnosis of diseases in the thorax. OBJECTIVE: To evaluate the complication rate and the diagnostic yield in computer tomography (CT)-guided core biopsies performed in a county hospital in Sweden. METHODS: Medical journals, spirometry results, pathology reports and CT scans were reviewed in 463 consecutive cases, where a transthoracic core biopsy was performed between January 2005 and December 2010. Of these 380 (82%) were lung lesions, 48 (10%) were mediastinal lesions and 35 (8%) were pleural lesions. RESULTS: All patients underwent a chest X-ray 4 hours post-biopsy and pneumothorax was seen in 156/463 (34%) patients: 137 after lung biopsy and 17 after mediastinal biopsy. Chest tube insertion was required for 27 (17%) of these patients (6% of all core biopsies). Small intraparenchymal hemorrhages and hemoptysis were observed with subjective difficulty in one case. The diagnostic yield for the 463 patients was 212 (46%) cases of lung cancer, 188 (41%) benign lesions and 39 (8%) pulmonary metastases. CONCLUSIONS: A transthoracic core biopsy ensures diagnosis with a low complication rate and is suitable as an outpatient procedure. An increased risk for pneumothorax was observed when the biopsied lesion was small or when emphysema was in the path of the biopsy needle. Reduced lung function pre-biopsy or emphysema in the path of the biopsy needle increased the need for chest tube treatment of pneumothorax. A CT-guided core biopsy is safe and applicable in a county hospital.

Association between high blood pressure and deep periodontal pockets: a nested case-referent study.

A hypertension screening project was performed jointly at a dental clinic and a primary health care centre. In this report the hypothesis that there is an association between high diastolic blood pressure and deep periodontal pockets was tested. A total of 1,239 consecutive patients aged 35-65 years had their blood pressure measured before the dental examination or had a known hypertension. Information on medical history and tobacco use was obtained by interview and dental status was recorded. Fifty-four subjects had known hypertension and 141 had previously unknown diastolic blood pressure >90 mmHg (cases). For each case an age, sex and tobacco-use matched referent was chosen from those with diastolic blood pressure < or =90 mmHg. Significantly more cases than referents had periodontal pockets > or = 5 millimeters deep. In multivariate analyses the prevalence of deep periodontal pockets was associated with blood pressure status also after adjustment for the small differences between the groups in age, sex, tobacco use and number of teeth. In conclusion there was an association between diastolic blood pressure and prevalent deep periodontal pockets. Whether the relationship is a causal one remains to be explored. Screening for high blood pressure at regularly visits at the dental clinic may give the dental care a new important role in the public health field.
