Chronic wounds are associated with significant clinical, economic and quality‐of‐life burden. Despite the variety of wound imaging systems available in the market for wound assessment and surveillance, few are clinically validated among patients of Asian ethnicity. We aimed to clinically validate the accuracy of a smartphone wound application (Tissue Analytics [TA], Net Health Systems Inc, Florida, USA), versus conventional wound measurements (visual approximation and paper rulers), in patients of Asian ethnicity with venous leg ulcers (VLU). A prospective cohort study of patients presenting with VLU to a specialist wound nurse clinic over a 5‐week duration was conducted. Each patient received seven wound measurements: one by a trained wound nurse clinician, and three separate wound measurements using TA on each of the iOS and Android operating systems. Inter‐rater and intra‐rater reliability between clinical and TA‐based measurements were analysed using intra‐class correlation statistics, with values of <0.5, 0.5 to 0.75, 0.75 to 0.9, and >0.9 indicating poor, moderate, good and excellent reliability, respectively. 82 patients (51% males), with a mean age at 65.8 years, completed the 5‐week study duration. 25 (30%) had underlying diabetes mellitus. Chinese, Malay and Indian ethnicity comprised 68%, 12% and 11%, respectively. The VLU healed in 26 (32%) of patients within the study period. In total, 358 wound episodes with 2334 wound images were analysed. Inter‐rater reliability for length, width and area between wound nurse measurements and TA application measurements was good (range 0.799‐0.919, P < 0.001). Separate measurements of intra‐rater reliability for length, width and area within the iOS or Android systems were excellent (range 0.967‐0.985 and range 0.977‐0.984 respectively, P < 0.001). Inter‐rater reliability between TA used on the iOS and Android systems was also excellent (0.987‐0.989, P < 0.001). Tissue Analytics, a smartphone wound application, is a useful adjunct for wound assessment and surveillance in VLU patients of Asian ethnicity. [ABSTRACT FROM AUTHOR]

Background: Retaining experienced critical care nurses (CCNs) remains a challenge for health care organizations. Nursing practice environment and resilience are both seen as modifiable factors in ameliorating the impact on CCNs' intention to leave and have not yet been explored in Malaysia. Aims and objectives: To assess the association between perceived nursing practice environment, resilience, and intention to leave among CCNs and to determine the effect of resilience on intention to leave after controlling for other independent variables. Design This was a cross‐sectional survey. Methods: The universal sampling method was used to recruit nurses from adult and paediatric (including neonatal) critical care units of a large public university hospital in Malaysia. Descriptive analysis and χ2 and hierarchical logistic regression tests were used to analyse the data. Results: A total of 229 CCNs completed the self‐administrated questionnaire. Of the nurses, 76.4% perceived their practice environment as being favourable, 54.1% were moderately resilient, and only 20% were intending to leave. The logistic regression model explained 13.1% of variance in intention to leave and suggested that being single, an unfavourable practice environment, and increasing resilience were significant predictors of nurses' intention to leave. Conclusion: This study found that an unfavourable practice environment is a strong predictor of intention to leave; however, further exploration is needed to explain the higher likelihood of expressing intention to leave among CCNs when their resilience level increases. Relevance to clinical practice: Looking into staff allocation and equality of workload assignments may improve the perception of the work environment and help minimize intention to leave among nurses.

Background: Nurses play a key role in the proper management of endotracheal tube (ETT) cuff pressure, which is important for patients' safety, so it is vital to improve nurses' knowledge on safe cuff management practices. Aims and objectives: This study aimed to evaluate the effectiveness of an educational intervention related to ETT cuff pressure management on improving and retaining critical care nurses' knowledge. Design: A single group pre‐post interventional study was conducted involving 112 registered nurses (RNs) from a 24‐bed adult general intensive care unit at a teaching hospital in Malaysia. Methods: The educational intervention included a theoretical session on endotracheal cuff pressure management and demonstration plus hands‐on practice with the conventional cuff pressure monitoring method. Nurses' knowledge was measured using a self‐administered questionnaire pre‐ and post‐intervention. Data were analysed using repeated measure analysis of variance and bivariate analysis. Results: In this study, 92% of the total number of RNs in the unit participated. A significant difference in mean knowledge score was noted between the pre‐ (mean = 8.13; SD = 1.53) and post‐intervention phases (3 months [mean = 8.97; SD = 1.57) and 9 months post‐intervention [mean = 10.34; SD = 1.08), P <.001), indicating significant knowledge acquisition and retention between the phases. Knowledge gained between the pre‐ and 9 months post‐intervention phases significantly differed according to nurses' educational level. Conclusions: This study supports existing evidence that ongoing educational interventions are essential to improve nurses' knowledge. However, further exploration is suggested to assess how well this knowledge is translated into clinical practice. Relevance to clinical practice: Regular educational programmes with current updates would enhance nurses' knowledge through proper practice and clinical decision‐making skills; this, in turn, would help to standardize cuff management practices.

ABSTRACT Aims This study aimed to determine attitudes and practices of intensive care unit ( ICU) nurses towards provision of oral care for intubated patients. Background Oral care is as an essential nursing intervention for intubated patients to maintain patient comfort and prevent colonization of dental plaque by respiratory pathogens. Design This was a cross-sectional study. Methods Data were collected from 93 ICU nurses of a teaching hospital in the East Coast of Peninsular Malaysia using a self-administered questionnaire. Results Some nurses agreed that oral cavity of intubated patients was difficult (40·8%) and unpleasant (16·2%) to clean, but all of them realized the importance of oral care and the majority (97·9%) would like to learn more about it. Most nurses reported providing oral care at least two times daily using various methods and products such as suction toothbrush (90·4%), manual toothbrush (49·5%), cotton swab (91·5%) and foam swab (65·7%). Chlorhexidine gluconate oral rinse was the preferred mouthwash (97·8%) and swabs (93·5%) solution although few used non-optimal products such as sodium bicarbonate (14·0%), tap water (4·3%) and hydrogen peroxide (3·2%) to wash their patients' mouths. While the majority of nurses agreed that oral care supplies and equipments were available (93·6%) and suitable (88·2%), most of them also thought they need better hospital support (88·2%). Conclusions The nurses' attitudes towards oral care were generally positive and most oral care methods were appropriate. However, some methods and products used were inconsistent with the current recommendations and they have mixed views about the suitability of oral care supplies and equipment provided by the hospital. Relevance to clinical practice Recommendations were made for providing standard oral care protocols for intubated patients and oral care training programs for ICU nurses to support delivery of quality patient care.

Background Sedation management is an integral component of critical care practice. It requires the greatest attention of critical care practitioners because it carries significant risks to patients. Therefore, it is imperative that nurses are aware of potential adverse consequences of sedation therapy and current sedation practice recommendations. Aims and objectives To evaluate the impact of an educational intervention on nurses' knowledge of sedation assessment and management. Designs and methods A quasi-experimental design with a pre- and post-test method was used. The educational intervention included theoretical sessions on assessing and managing sedation and hands-on sedation assessment practice using the Richmond Agitation Sedation Scale. Its effect was measured using self-administered questionnaire, completed at the baseline level and 3 months following the intervention. Results Participants were 68 registered nurses from an intensive care unit of a teaching hospital in Malaysia. Significant increases in overall mean knowledge scores were observed from pre- to post-intervention phases (mean of 79·00 versus 102·00, p < 0·001). Nurses with fewer than 5 years of work experience, less than 26 years old, and with a only basic nursing education had significantly greater level of knowledge improvement at the post-intervention phase compared to other colleagues, with mean differences of 24·64 ( p = 0·001), 23·81 ( p = 0·027) and 27·25 ( p = 0·0001), respectively. A repeated-measures analysis of variance revealed a statistically significant effect of educational intervention on knowledge score after controlling for age, years of work and level of nursing education ( p = 0·0001, ηp2 = 0·431). Conclusion An educational intervention consisting of theoretical sessions and hands-on sedation assessment practice was found effective in improving nurses' knowledge and understanding of sedation management. Relevance to clinical practice This study highlighted the importance of continuing education to increase nurses' understanding of intensive care practices, which is vital for improving the quality of patient care.

Objectives Assessment of dental treatment needs has predominantly been based on the normative approach, despite its numerous limitations. The sociodental approach is a more rational method of needs assessment as it incorporates broader concepts of health and needs and behavioural propensity. This study compares estimates of periodontal dental treatment needs and workforce requirements for different skill mixes using normative and sociodental approaches among a sample of adults in Malaysia. Methods A cross-sectional study was carried out on 732 Malaysian adults aged 30-54 years. Subjects' normative and sociodental needs for periodontal treatment were assessed using WHO criteria, an oral health-related quality of life measure (the Oral Impacts on Daily Performances index), and behavioural propensity measures for toothbrushing and smoking behaviour. The proportion of subjects requiring periodontal treatment and the numbers of dentists and dental therapists required to treat them using the normative and sociodental approach were compared using different skill mix models. Results The estimates of need for periodontal treatment using the sociodental approach were 90% lower than the respective estimates using the normative need method. Overall, 14.43 dentists would be required per 100 000 people using the normative approach compared to 2.32 for the sociodental approach. When skill mix models were used, the number of dentists required decreased by almost 70% when more periodontal procedures were delegated to dental therapists. Conclusions Using the sociodental approach resulted in much lower estimates of dental need and workforce requirements for periodontal treatment than using the normative method. Using dental therapists markedly reduced the numbers of dentists needed for periodontal treatment. [ABSTRACT FROM AUTHOR]

Background and Objective Studies of peri-implant soft tissue on in vivo models are commonly based on histological sections prepared using undecalcified or 'fracture' techniques. These techniques require the cutting or removal of implant during the specimen preparation process. The aim of this study is to explore a new impression technique that does not require any cutting or removal of implant for contour analysis of soft tissue around four types of titanium (Ti) surface roughness using an in vitro three-dimensional oral mucosal model (3D OMM). Methods The 3D OMM was constructed by co-culturing a keratinocyte cell line TR146 and human oral fibroblasts on to an acellular dermis scaffold. On the fourth day, a Ti disk was placed into the model. Four types of Ti surface topographies, i.e. polished, machined, sandblasted and anodized were tested. After 10 d of culture, the specimens were processed based on undecalcified (ground sectioning), electropolishing and impression techniques for contour analysis of the implant-soft tissue interface. Results Under light microscopic examination of the ground and electropolishing sections, it was found that the cell line-based oral mucosa formed a peri-implant-like epithelium attachment on to all four types of Ti surfaces. In contour analysis, the most common contour observed between the cell line-based oral mucosa and Ti surface was at an angle ranging between 45° and 90°. Conclusion The in vitro cell line-based 3 D OMM formed a peri-implant-like epithelium at the implant-soft tissue interface. The contour of the implant-soft tissue interface for the four types of Ti surface was not significantly different. [ABSTRACT FROM AUTHOR]

Diabet. Med. 29, 911-917 (2012) Abstract Aims To study whether HbA1c, and its relationship with fasting plasma glucose, was significantly different among Chinese, Malays and Indians in Singapore. Methods A sample of 3895 individuals without known diabetes underwent detailed interview and health examination, including anthropometric and biochemical evaluation, between 2004 and 2007. Pearson's correlation, analysis of variance and multiple linear regression analyses were used to examine the influence of ethnicity on HbA1c. Results As fasting plasma glucose increased, HbA1c increased more in Malays and Indians compared with Chinese after adjustment for age, gender, waist circumference, serum cholesterol, serum triglyceride and homeostasis model assessment of insulin resistance ( P-interaction < 0.001). This translates to an HbA1c difference of 1.1 mmol/mol (0.1%, Indians vs. Chinese), and 0.9 mmol/mol (0.08%, Malays vs. Chinese) at fasting plasma glucose 5.6 mmol/l (the American Diabetes Association criterion for impaired fasting glycaemia); and 2.1 mmol/mol (0.19%, Indians vs. Chinese) and 2.6 mmol/mol (0.24%, Malays vs. Chinese) at fasting plasma glucose 7.0 mmol/l, the diagnostic criterion for diabetes mellitus. Conclusions Using HbA1c in place of fasting plasma glucose will reclassify different proportions of the population in different ethnic groups. This may have implications in interpretation of HbA1c results across ethnic groups and the use of HbA1c for diagnosing diabetes mellitus. [ABSTRACT FROM AUTHOR]
