The impact of a computerized care records service (CRS) on doctors’ work patterns in urological outpatient clinics

Health 2011年第11期3卷 703-707页

作者： Stefanos Kachrilas Christian Bach Pryia Kumar Faruqz zaman Nicola Dickens Junaid Masood noor Buchholz 不详

Objective: Government targets to reduce waiting times are putting enormous pressures on outpatient services. The implementation of an electronic care records service (CRS) at our hospital in 2008 has led to widespread press coverage of ensuing chaos in clinical administration. We wanted to know how this new electronic system impacted on our working patterns in outpatient clinics and – more specifically – on the time actually spent with the patients. Material & methods: This study was performed 4 and 12 months after implementation of CRS to assess its impact on the time distribution in clinic. Senior doctors were monitored with a stop clock during consultations. Timings for pre- and post-consultation administration, and the actual consultation with the patient were recorded. A total of 170 consultations were evaluated in this way. Results: The key findings were that the total time needed to spend on a urological outpatient of 16 minutes remains unchanged from the pre-CRS era, but a majority (57%) of this time is spent in administration on the computer without the patient involved. Conclusion: No more than 15 patients should be seen in a 4 hour outpatient clinic per doctor. This recommendation drawn up by BAUS before CRS remains still valid. Patient administration related to the consultation that has previously been done by administrative aides is now to be done by the doctors on the computer in the same consultation session. Intended to streamline patient pathways, this does reduce the quality interaction-time between doctor and patients significantly.

The incidence of dengue in Malaysia has shown an increasing trend since the year 2000. Vector control is the primary approach for dengue control in Malaysia. There is an urgent need for new or modified approaches such as the residual spraying on the outer walls that can potentially last long enough to control the Aedes population, particularly in the outbreak-prone areas. In this field study, we conducted outdoor residual spraying (ORS) using a newly formulated polymer-enhanced suspension concentrate (SC-PE) of deltamethrin. The objectives of this study were to evaluate the efficacy of ORS using deltamethrin SC-PE and its effect on wild Aedes populations and to assess its residual bio-efficacy on painted cement walls against the pyrethroid-susceptible strains of laboratory-reared Aedes mosquitoes. Three rounds of spraying in a four-month cycle were conducted between 2014 and 2015 in four residential areas (low-rise and high-rise housing types) in Hulu Langat, Selangor. The bio-efficacy of the insecticide was evaluated by assessing its impact on vector population using ovitrap surveillance. Standard WHO wall deposit bioassay was adapted to determine bio-efficacy of deltamethrin, i.e. post 30 min knockdown and post 24 h mortality after exposure. During the treatment period, we observed significant reductions in the population of Ae. albopictus in the sprayed low-rise housing in both semi-indoor and outdoor environments, while in the high-rise housing, there was also a significant decline in Ae. aegypti population in the semi-indoor environment. The evaluation of the residual bio-efficacy of deltamethrin SC-PE against laboratory-reared Aedes mosquitoes showed that the insecticide lasted longer in the high-rise housing compared to the low-rise housing with >80% mortality achieved continuously for 16 weeks. We provide initial evidence on residual efficacy of deltamethrin SC-PE in reducing Aedes population size in the low-rise and high-rise housing. Our results showed tha
