Primary care physicians' response to pandemic influenza in Hong Kong: a mixed quantitative and qualitative study.

ABSTRACT:

Objectives

The current study was conducted to use a developed framework to appraise the public primary care response to pandemic 2009 influenza A H1N1 virus in Hong Kong in 2009.

Methods

A cross-sectional survey was conducted of 300 doctors working in public primary care clinics. In addition, a qualitative study was conducted in two selected general outpatient clinics (GOPCs) with 10 doctors between September and December 2009.

Results

We found that there was an increase in clinical service demand for public primary care doctors and that there was lower compliance with hand washing as compared to the wearing of masks among GOPC doctors during the study period.

Conclusions

Since hand hygiene and influenza vaccination are effective methods to prevent the spread of influenza infection, future studies should explore the reasons for non-compliance with these preventive behaviors among doctors. More education and training in dealing with influenza A H1N1 infection may be needed.

Project description:BACKGROUND:Serial cross-sectional data on antibody levels to the 2009 pandemic H1N1 influenza A virus from a population can be used to estimate the infection attack rates and immunity against future infection in the community. METHODS:From April through December 2009, we obtained 12,217 serum specimens from blood donors (aged 16-59 years), 2520 specimens from hospital outpatients (aged 5-59 years), and 917 specimens from subjects involved in a community pediatric cohort study (aged 5-14 years). We estimated infection attack rates by comparing the proportions of specimens with antibody titers ? 1:40 by viral microneutralization before and after the first wave of the pandemic. Estimates were validated using paired serum samples from 324 individuals that spanned the first wave. Combining these estimates with epidemiologic surveillance data, we calculated the proportion of infections that led to hospitalization, admission to the intensive care unit (ICU), and death. RESULTS:We found that 3.3% and 14% of persons aged 5-59 years had antibody titers ? 1:40 before and after the first wave, respectively. The overall attack rate was 10.7%, with age stratification as follows: 43.4% in persons aged 5-14 years, 15.8% in persons aged 15-19 years, 11.8% in persons aged 20-29 years, and 4%-4.6% in persons aged 30-59 years. Case-hospitalization rates were 0.47%-0.87% among persons aged 5-59 years. Case-ICU rates were 7.9 cases per 100,000 infections in persons aged 5-14 years and 75 cases per 100,000 infections in persons aged 50-59 years, respectively. Case-fatality rates were 0.4 cases per 100,000 infections in persons aged 5-14 years and 26.5 cases per 100,000 infections in persons aged 50-59 years, respectively. CONCLUSIONS:Almost half of all school-aged children in Hong Kong were infected during the first wave. Compared with school children aged 5-14 years, older adults aged 50-59 years had 9.5 and 66 times higher risks of ICU admission and death if infected, respectively.
