A randomized controlled study of acupuncture for pain relief during first trimester surgical termination of pregnancy performed under local analgesia

BACKGROUND

Acupuncture reduces pain levels in many painful conditions. This study compared pain levels during surgical termination of first trimester pregnancy by suction evacuation (SE) under local analgesia with and without the use of acupuncture.

METHODS

In all, 60 nulliparous women undergoing SE before 10 weeks of gestation were randomly assigned into one of the following three groups in a 1:1:1 ratio according to a computer-generated randomization list. In the control group, women received oral diazepam 5 mg and intramuscular (i.m.) injection of pethidine 30 and 15 min, respectively, prior to SE. In the acupuncture group, women received acupuncture 10 min before SE until the end of SE while oral diazepam 5 mg and i.m. injection of normal saline were given. In the combined group, women received acupuncture in addition to the drugs in the control group. Data from 52 participants were analysed. Pain scores during and after SE, post-operative side-effects and satisfaction levels were compared.

RESULTS

The three groups had similar baseline characteristics. The median pain levels during SE differed significantly between the control, acupuncture, and combined groups (80, 50 and 66 mm, respectively, p = 0.03). Pain levels during SE in the acupuncture and combined groups were significantly lower than that of the control group. However, the anxiety scores did not differ between the three groups after SE (p = 0.86).

CONCLUSION

Acupuncture can provide additional benefit in terms of pain relief in women undergoing first trimester termination of pregnancy by SE under local analgesia.

Cross-border reproductive care use by women with infertility in Hong Kong: cross-sectional survey

OBJECTIVES

Cross-border reproductive care (CBRC) is an increasingly common global phenomenon, but there is a lack of information regarding its frequency among residents of Hong Kong. This study aimed to evaluate the use of CBRC and the factors affecting its use among residents of Hong Kong.

METHODS

This cross-sectional questionnaire study collected data from 1204 women with infertility who attended Hong Kong Hospital Authority and Family Planning Association infertility clinics.

RESULTS

In total, 178 women (14.8% of all respondents) had used CBRC. Among respondents who had not used CBRC, 36.3% planned to use or would consider it. The main factors influencing the likelihood of using CBRC among women with infertility in Hong Kong use were long waiting times in the public sector and high cost in the private sector. Taiwan was the most preferred destination for CBRC (69.6% of respondents). Most information concerning CBRC was accessed via the internet. More than two thirds of respondents believed that the government in Hong Kong should formulate some regulations or guidance regarding CBRC.

CONCLUSION

Nearly one in six women with infertility in Hong Kong had used CBRC. Among women who had not used CBRC, more than one third planned to use or would consider it. The main factors influencing the likelihood of CBRC use were long waiting times in the public sector and high cost in the private sector. These results will help clinicians to more effectively counsel patients considering CBRC and facilitate infertility services planning by authorities in Hong Kong.

Expanded Carrier Screening in Chinese Population - A Survey on Views and Acceptance of Pregnant and Non-Pregnant Women

Objective

Recessive genetic diseases impose physical and psychological impacts to both newborns and parents who may not be aware of being carriers. Expanded carrier screening (ECS) allows screening for multiple genetic conditions at the same time. Whether or not such non-targeted panethnic approach of genetic carrier screening should replace the conventional targeted approach remains controversial. There is limited data on view and acceptance of ECS in general population, as well as the optimal timing of offering ECS to women. This study assesses views and acceptance of ECS in both pregnant women and non-pregnant women seeking fertility counseling or checkup and their reasons for accepting or declining ECS.

Materials and methods

This is a questionnaire survey with ECS information in the form of pamphlets distributed from December 2016 to end of 2018. Women were recruited from the antenatal clinics and the assisted reproductive unit at the Department of Obstetrics and Gynaecology, Queen Mary Hospital and the prepregnancy counseling clinic at the Family Planning Association of Hong Kong.

Results

A total of 923 women were recruited: 623 pregnant women and 300 non-pregnant women. There were significantly more non-pregnant women accepting ECS compared to pregnant women (70.7% vs. 61.2%). Eight hundred and sixty-eight (94%) women perceived ECS as at least as effective as or superior to traditional targeted screening. Significantly more pregnant women have heard about ECS compared with non-pregnant women (42.4% vs. 32.3%, P = 0.0197). Majority of women showed lack of understanding about ECS despite reading pamphlets that were given to them prior to filling in the questionnaires. Cost of ECS was a major reason for declining ECS, 28% (n = 256). Significantly more pregnant women worried about anxiety caused by ECS compared with the non-pregnant group (21.1% vs. 7.4%, P = 0.0006).

Conclusion

Our study demonstrates that expanded carrier screening was perceived as a better screening by most women. Prepregnancy ECS maybe a better approach than ECS during pregnancy, as it allows more reproductive options and may cause less anxiety. Nevertheless, implementation of universal panethnic ECS will need more patient education, ways to reduce anxiety, and consensus on optimal timing in offering ECS.

Infection control in residential care homes for the elderly in Hong Kong (2005-2014)

INTRODUCTION

This serial cross-sectional survey study aimed to review the trend in various infection control practices in residential care homes for the elderly (RCHEs) in Hong Kong from 2005 to 2014.

METHODS

Annual cross-sectional surveys were conducted at all RCHEs in Hong Kong, including self-administered questionnaires, on-site interviews, inspections, and assessments conducted by trained nurses, from 2005 to 2014. In all, 98.5% to 100% of all RCHEs were surveyed each year based on the list of licensed RCHEs in Hong Kong.

RESULTS

There was a substantial increase in the proportion of RCHE residents aged ≥85 years, from 40.0% in 2005 to 50.2% in 2014 (P=0.002). The percentage of RCHE residents with special care needs also increased, from 22.3% in 2005 to 32.6% in 2014 for residents with dementia (P<0.001) and from 3.4% in 2005 to 5.0% in 2014 for residents with a long-term indwelling urinary catheter (P<0.001). The proportion of RCHEs with separate rooms for isolation areas ranged from 73.6% to 80% but did not show any significant trend over the study period. The proportion of RCHEs with alcohol hand rub available showed an increasing trend from 25.4% in 2006 to 99.2% in 2014 (P=0.008). The proportion of health or care workers (who were not the designated infection control officers) passing skills tests on hand washing techniques increased from 79.2% in 2006 to 91.5% in 2014 (P=0.02). An increasing trend was also observed for the proportion of infection control officers who were able to prepare properly diluted bleach solution, from 71.5% in 2005 to 92.2% in 2014 (P=0.002).

CONCLUSIONS

For infection control practice to continue improving, more effort should be made to enhance and maintain proper practice, and to mitigate the challenge posed by the high turnover rates of healthcare workers in RCHEs. Introduction of self-audits on infection control practices should be considered.

Community-based survey of knowledge of, attitudes to and practice of colorectal cancer screening in Hong Kong

OBJECTIVE

We aimed to investigate the knowledge, attitudes and practice of colorectal cancer (CRC) and screening in the community to complement the introduction of population-based CRC screening in Hong Kong SAR, China.

METHODS

Clients attending the Family Planning Association of Hong Kong clinics from March to June 2016 were randomly invited to participate in this questionnaire survey.

RESULTS

Knowledge of CRC and screening for it was still deficient in the community. Respondents scored less than half on their knowledge of the symptoms and screening methods of CRC as well as on the local screening policy. Fewer than 30% knew that CRC can be asymptomatic and they had insufficient knowledge of primary lifestyle prevention of CRC. However, most (86.0%) would like to participate in CRC screening. The cost and trouble involved were the two main reasons given for not wanting to do so. Only 14.0% of the whole sample and 27.0% of those aged 50 years or above had undergone CRC screening irrespective of screening method. One-fifth of those who had been screened had some abnormality, with a cancer detection rate of 2.2%. Employment, income, knowledge and perception of risk were major determinants of their decision to undergo screening.

CONCLUSIONS

To reduce the morbidity and mortality of CRC significantly, average risk and high-risk groups should be encouraged to come forward for screening even if they are asymptomatic. Educating the population, simplifying the screening procedure and offering financial support by the government are keys to success.

Operational definitions improve reliability of the age-related white matter changes scale

BACKGROUND AND PURPOSE

Although the age-related white matter changes (ARWMC) scale has been advocated to be applicable to both MRI and CT for assessing the severity of WMC, its inter-rater reliability on CT is only fair. We aimed to operationalize the ARWMC scale and investigate the effect of this operationalization on the reliability and validity on MRI and CT.

METHODS

Operational definitions of the ARWMC scale were derived from Erkinjuntti research criteria for subcortical vascular dementia and Scheltens scale. Using original and operationalized ARWMC scale, eight observers recorded the time for rating per MRI and per CT. We investigated the inter-rater and intrarater reliability as well as validity against volume using data from 97 stroke patients.

RESULTS

Inter-rater reliability of the operationalized scale on CT (0.874, 95% confidence interval [0.780-0.934]) was better than the original scale (0.569, 95% confidence interval [0.247-0.775]). Its intrarater reliability on CT (0.869) and reliability on MRI (inter-rater: 0.860; intrarater: 0.838) was comparable with the original scale (CT intrarater: 0.750 and on MRI inter-rater: 0.845; intrarater: 0.853). The time required to administer the operationalized scale (4'2″ for MRI and 1'18″ for CT) was similar to that of the original scale (3'56″ for MRI and 1'16″ for CT). The original scale and operationalized scale also significantly correlated with WMC volume (operationalized scale ρ = 0.613, P < 0.001, original scale ρ = 0.638, P < 0.001).

CONCLUSION

Operational definitions improve the inter-rater reliability of ARWMC scale on CT, and it correlates with volumetric measurement.
