What do primary care doctors get out of a year-long postgraduate course in community psychological medicine?

OBJECTIVE

There are increasing expectations on primary care doctors to care for patients with common mental health problems. This study examines the outcomes of a postgraduate training course in psychological medicine for primary care doctors.

METHODS

A questionnaire developed by the research team was sent to the Course graduates (year 2003-2007). A retrospective design was adopted to compare their clinical practice characteristics before and after the Course. Differences in the ratings by the respondents before and after the Course were analyzed using the nonparametric Wilcoxon signed rank test.

RESULTS

Sixty-nine graduates replied with a response rate of 58.5% (69/118). Most respondents were confident of diagnosing (96.9%) and managing (97.0%) common mental health problems after the Course, compared to 50.0% and 50.7%, respectively, before the Course. Most graduates had modified their approach, increased their attention and empathy to patients with mental health problems. The percentage of respondents having enough time to treat these patients had increased from 55.8% to 72.1%. The median number of patients with mental health problems seen per week was in the range of 3-6 before, and had increased to the range of 7-10 after the Course. The proportion of respondents being confident of making appropriate referrals had increased from 72.8% to 97.0%, while the number of referrals to psychiatrists had dropped significantly.

CONCLUSIONS

The Course is effective in improving graduates' confidence, attitude, and skills in treating patients with common mental health problems. There are significant increases in the number of mental health patients handled, increased confidence in making referrals to psychiatrists, and decreased percentage of patients being referred.

PBL curriculum improves medical students' participation in small-group tutorials

BACKGROUND

Group learning is the core of problem-based learning (PBL) but has not been extensively studied, especially in Asian students.

METHODS

This study compared students of PBL and non-PBL curricula in students' talking time and participation in small-group tutorials in a medical school in Asia. The proportions of student talking of 46 tutorials in three teaching rotations of the PBL curriculum and those of 43 corresponding tutorials in the non-PBL curriculum were counted. Twelve videotapes of tutorials (six from each curriculum), stratified for tutor, case scenario and students' learning stage, were randomly selected and transcribed. They were rated with the group-interaction (5 items) and active-participation (four items) tutorial assessment scales developed by Valle et al. These outcomes were compared between the students of PBL and non-PBL curricula.

RESULTS

Students from the PBL curriculum talked significantly more. In only two (4.7%) of 43 tutorials in the non-PBL curriculum did the students talk more than the tutors; but students talked more than the tutors in 17 (37.0%) of 46 tutorials in the PBL curriculum. PBL students scored significantly higher than non-PBL students in all items except one item (respect to peers) of the tutorial assessment scales, and in the mean scores of both the group interaction scale (items 1-5) and the active participation scale (items 6-9).

CONCLUSIONS

The results suggested that PBL starting from the early years of a medical curriculum was associated with more active student participation, interaction and collaboration in small-group tutorials.

Why do primary care doctors undertake postgraduate diploma studies in a mixed private/public Asian setting?

OBJECTIVE

The aim of this study was to examine the reasons why primary care doctors undertake postgraduate diploma studies in a mixed private/public Asian setting.

METHODS

Twenty four past or current postgraduate diploma students of the family medicine unit (FMU) of the University of Hong Kong participated in three focus group interviews. A structured questionnaire was constructed based on the qualitative data collected and was sent to 328 former applicants of postgraduate diploma studies at FMU.

RESULTS

"Upgrading medical knowledge and skills" and "improving quality of practice" were two of the factors that most of the respondents considered to be significant in motivating them to undertake postgraduate diploma studies. "Time constraint" and "workload in practice" were however the most significant demotivating factors. Financial issues were more seriously considered by the junior than the senior doctors. To be able to "expand patient base and/or number" was considered to be a significant factor by the private doctors who were also keen to "improve communication and relationship with patients".

CONCLUSION

These findings suggest that there are mixed reasons for primary care doctors to undertake postgraduate diploma studies. Course organisers should take into consideration these various reasons in planning their programmes.

The SF-36 summary scales were valid, reliable, and equivalent in a Chinese population

OBJECTIVES

To find out whether the SF-36 physical and mental health summary (PCS and MCS) scales are valid and equivalent in the Chinese population in Hong Kong (HK).

STUDY DESIGN AND SETTING

The SF-36 data of a cross-sectional study on 2,410 Chinese adults randomly selected from the general population in HK were analyzed.

RESULTS

The hypothesized two-factor structure of the physical and mental health summary scales (PCS and MCS) was replicated and the expected differences in scores between known morbidity groups were shown. The internal reliability coefficients of the PCS and MCS scales ranged from 0.85 to 0.87. The effect size differences between the U.S. standard and HK-specific PCS and MCS scores were mostly <0.5. The effect size differences in the standard PCS and MCS scores of specific groups between the U.S. and H.K. populations were all <0.5.

CONCLUSION

The PCS and MCS scales were applicable to the Chinese population in HK. The high level of measurement equivalence of the scales between the U.S. and H.K. populations suggests that data pooling between the two populations could be possible. To our knowledge, this is the first study to show that the SF-36 summary scales are valid and equivalent in an Asian population.

Is the standard SF-12 health survey valid and equivalent for a Chinese population?

INTRODUCTION

Chinese is the world's largest ethnic group but few health-related quality of life (HRQoL) measures have been tested on them. The aim of this study was to determine if the standard SF-12 was valid and equivalent for a Chinese population.

METHODS

The SF-36 data of 2410 Chinese adults randomly selected from the general population of Hong Kong (HK) were analysed. The Chinese (HK) specific SF-12 items and scoring algorithm were derived from the HK Chinese population data by multiple regressions. The SF-36 PCS and MCS scores were used as criteria to assess the content and criterion validity of the SF-12. The standard and Chinese (HK) specific SF-12 PCS and MCS scores were compared for equivalence.

RESULTS

The standard SF-12 explained 82% and 89% of the variance of the SF-36 PCS and MCS scores, respectively, and the effect size differences between the standard SF-36 and SF-12 scores were less than 0.3. Six of the Chinese (HK) specific SF-12 items were different from those of the standard SF-12, but the effect size differences between the Chinese (HK) specific and standard SF-12 scores were mostly less than 0.3.

CONCLUSIONS

The standard SF-12 was valid and equivalent for the Chinese, which would enable more Chinese to be included in clinical trials that measure HRQoL.
