Effect of a theory-driven educational intervention on the level of knowledge, attitudes, and assessment practices regarding breakthrough cancer pain (BTCP) management among medical nurses in Hong Kong
تأثیر مداخله آموزشی مبتنی بر تئوری بر سطح دانش، نگرش ها و شیوه های ارزیابی در مورد مدیریت سرطان پیشرفته (BTCP) در پرستاران پزشکی در هنگ کنگ-2021 Purpose: To examine the effect of an educational intervention intended to improve medical nurses’ adherence to
breakthrough cancer pain (BTCP) assessment practices and their level of knowledge, attitudes and perceived
assessment practices regarding BTCP management.
Methods: Nurses working in a regional hospital were recruited to this quasi-experimental study. The intervention
group received a 3-h educational workshop and one session of individual clinical instruction, whilst the control
group did not receive any intervention. Chart audits were performed to examine adherence to BTCP assessment
practices as the primary outcome. A self-developed questionnaire was used to measure nurses’ knowledge, at-
titudes and perceived assessment practices regarding BTCP management as the secondary outcomes. The chi-
square or Fisher’s exact test was used to compare the rate of adherence to BTCP assessment practices between
groups. A generalised estimating equation was used to compare changes in knowledge, attitudes, and perceived
assessment practices between groups over time.
Results: One hundred and five nurses completed the study. The chart audits revealed a significantly higher rate of
adherence to BTCP assessment practices in the intervention group after the intervention (p < .05). The inter-
vention group exhibited significant positive changes in scores for knowledge (β = 25.49, p < .001), attitude (β =
0.98 to 2.81, p < .01), and their perceived assessment practices (β = 1.33 to 3.14, p < .002) when compared with
the control group.
Conclusions: This theory-driven educational intervention significantly improved the medical nurses’ adherence to
BTCP assessment practices and their level of knowledge attitudes and perceived assessment practices regarding
BTCP management. keywords: درد سرطان دستیابی به موفقیت | تحصیلات | پرستاران | دانش | نگرش های | ارزیابی | شیوه ها | Breakthrough cancer pain | Education | Nurses | Knowledge | Attitudes | Assessment | Practices |

Quantile regression in big data: A divide and conquer based strategy
رگرسیون کمی در داده های بزرگ: یک استراتژی مبتنی بر تقسیم و غلبه-2020 Quantile regression, which analyzes the conditional distribution of outcomes given a set
of covariates, has been widely used in many fields. However, the volume and velocity of
big data make the estimation of quantile regression model extremely difficult due to the
intensive computation and the limited storage. Based on divide and conquer strategy, a
simple and efficient method is proposed to address this problem. The proposed approach
only keeps summary statistics of each data block and then can use them to reconstruct
the estimator of the entire data with asymptotically negligible approximation error.
This property makes the proposed method particularly appealing when data blocks are
retained in multiple servers or come in the form of data stream. Furthermore, the
proposed estimator is shown to be consistent and asymptotically as efficient as the
estimating equation estimator calculated using the entire data together when certain
conditions hold. The merits of the proposed method are illustrated using both simulation
studies and real data analysis Keywords: Data stream | Divide and conquer | Estimating equation | Massive data sets | Quantile regression |
