BACKGROUND Preoperative assessment reduces the risk of poor perioperative outcome and reduces cost of a specific group of perioperative candidates. The implementation of a preoperative digital tool may help to improve guideline adherence. MyPreOp®(Ultramed Ltd, Penryn, UK) is a web-based questionnaire designed to replace paper-based preoperative assessments. OBJECTIVE The study aimed to assess the user experience of MyPreOp®, investigate the factors affecting completion times, and devise a method of administering a validated usability scale without negatively affecting completion times. METHODS Anonymised datasets were extracted from the MyPreOp® system. The data collected included age, gender, American Society of Anesthesiology physical classification status, and time taken to complete the assessment. Two user experience evaluations were used: In Phase 1, two questions asking about overall experience and ease of use; and in Phase 2, a previously validated usability questionnaire, with its 20 questions equally distributed among five succeeding patient cohorts. There were 2593 respondents in total (Phase 1: n=1193; Phase 2: n=1400). RESULTS MyPreOp®scored well in both phases. In Phase 1, 80% of respondents had a good or better experience and 90% found it easy to use. The usability rating in Phase 2 was 4.13 (out of a maximum of 5) indicating high usability. Average completion time was 46.95 minutes (sd=25.83). The implementation of the longer usability evaluation scale in Phase 2 did not negatively impact completion times. Age and physical status were found to influence completion times but strength of the correlation was only moderate. CONCLUSIONS MyPreOp® rates high in both user experience and usability. The method of dividing the questionnaire into five blocks is both valid and does not negatively affect completion times. Further research into the factors affecting completion time is recommended.

Purpose: To identify the optimal spatial and dimensional requirements of grab bars that support independent and assisted transfers by older adults and their care providers. Background: Although research has demonstrated that toilet grab bars based on the Americans with Disabilities Act (ADA) Accessibility Standards do not meet the needs of older adults, the specific dimensional requirements for alternative configurations are unknown. Methods: A two-phased study with older adults and care providers in residential facilities was conducted to determine the optimal requirements for grab bars. Seniors and caregivers in skilled nursing facilities performed transfers using a mock-up toilet. In Phase 1, participants evaluated three grab bar configurations to identify optimal characteristics for safety, ease of use, comfort, and helpfulness. These characteristics were then validated for using ability-matched samples in Phase 2. Results: The optimal configuration derived in Phase 1 included fold-down grab bars on both sides of the toilet (14" from centerline [CL] of toilet, 32" above the floor, and extended a minimum of 6" in front of the toilet) with one side open and a sidewall 24" from CL of toilet on the other. Phase 2 feedback was significantly positive for independent and one-person transfers and somewhat lower, albeit still positive, for two-person transfers. Conclusion: The study provides substantial evidence that bilateral grab bars are significantly more effective than those that comply with current ADA Accessibility Standards. Findings provide specific spatial and dimensional attributes for grab bar configurations that would be most effective in senior facilities.

ObjectivesThis study aimed to investigate the effectiveness of pharmacist intervention in reducing and preventing prescribing errors of investigational drugs for cancer patients.Materials and methodsA retrospective study was conducted during two periods: a baseline period from December 2015 to June 2016 and an intervention period from July 2016 to February 2017. The investigational drug service (IDS) pharmacists performed active interventions during the intervention period.ResultsAmong 12,387 investigational drug orders, 395 (6.1%) prescribing errors were detected in 6477 orders at the baseline period, and 278 errors (4.7%) were detected in 5,910 orders at the intervention period. To identify factors that affect prescribing errors, three models were constructed for the multivariate analysis. Among factors affecting prescribing errors, sponsor initiated trial (SIT) was the strongest factor (AOR: 4.16, 95% CI: 3.31–5.23). Pharmacist intervention reduced prescribing errors by at least 25% in all constructed models after adjusting for confounding variables. Prescribing errors were 1.3 times higher when dealing with intravenous medications than when dealing with oral medications. There were 60% fewer prescribing errors in the blinded study than in the open study. SIT and multi-center/multi-nation studies had 4.2 and 2.4 times more frequent prescribing errors than in investigator-initiated trials (IIT) and single-center/single-nation studies, respectively. Fewer errors occurred in phase 2 and trials covering both phase 1 and phase 2 (phase 1/2) than in phase 3 trials.ConclusionsThe IDS pharmacist intervention in cancer clinical trials was associated with significant reductions in prescribing errors and may lead to increased medication safety.

The Impact

Background In Thailand, children born in government hospitals receive a maternal and child health handbook (MCHH). However, when a new MCHH edition is released, those with the previous editions do not have access to the updated information. A mobile app is an appealing platform to fill this gap. We developed a mobile app called “KhunLook” as an interactive electronic MCHH intended to assist parents in child health supervision. Objective This study describes the user requirements and development of the KhunLook mobile app, validity of parents’ growth assessments, and parents’ evaluation of feasibility and acceptability of the app. Methods Phase 1 was a qualitative study using individual interviews. The interview data were used to revise the prototype. In phase 2, parents were randomly assigned to assess their children’s growth with the app or the MCHH. The outcomes were compared to those of the physician’s assessment, and congruence was determined. In phase 3, parents evaluated the feasibility and acceptability of the app in comparison to the MCHH through a web-based survey. Results Four health care providers and 8 parents participated in phase 1. Two themes were identified: (1) the mobile app potentially counters parents’ infrequent use of the MCHH with accuracy, attractiveness, convenience, and simplicity, and (2) health supervision needs to be standard, up-to-date, and understandable. KhunLook was publicly launched with a family page and 7 key features: growth and nutrition, development, immunizations, oral health, reminders for the next appointment, memories, and health advice. In phase 2, 56 parents participated in the growth parameter assessments; 34 were in the App group and 22 in the MCHH group. The outcomes of the growth parameter assessments between parents and physicians in both the App and MCHH groups were not significantly different. The congruence proportions were higher in the App group for weight and head circumference, but the differences were not statistically significant. In phase 3, 356 parents from all over Thailand participated in a web-based survey. Parents rated the app feasibility as “very easy to easy” to use at higher proportions than the MCHH in all health assessment domains (growth, development, and immunizations) and ease-of-use domains with statistical significance (P<.001). The KhunLook app received a significantly higher mean score (8.59/10) than the MCHH (7.6/10) (P<.001). Most parents (317/356, 89.0%) preferred the app over MCHH. Further, 93.5% (333/356) of the parents stated that they would continue to use the app and 96.9% (345/356) would recommend others to use it. Conclusions KhunLook, a Thai mobile app for child health supervision, was developed, validated for growth assessments, and was well accepted for ease-of-use by parents. Further studies should be conducted with a large scale of users, and the impact of this app on health behaviors and health outcomes must be evaluated.
