HIV prevalence is high in Liangshan, China (1.1 %). In 2012, people who inject drugs (PWID) in Xichang, the capital city, contributed to 60.0 % of the HIV infections. The goal of the current study was to examine the feasibility of implementing pharmacy-delivered harm reduction services (PDHRS) for PWID.
Face-to-face structured interviews with 403 PWID included questions on PWID’s experiences of syringe services and their specific experiences, acceptance, and potential usage of PDHRS.
There were some reports of harassment/bad treatment from pharmacists (12.2 %) and police (17.6 %). Non-prescription syringe sales (NPSS) from pharmacies in single piece were the main source (82.1 %) of syringes. 72.5 % of PWID reported visiting 31.5 % of the identified pharmacies. Most (74.7 %) PWID disposed of their used syringes by throwing them away. Only one PWID brought used syringes back to a pharmacy in the past 30 days. Half of the PDHRS, such as printed materials about HIV, Hepatitis C and STIs; risk reduction services; (16.9 %) and sharps container to dispose of syringes (0.2 %) were offered by a few pharmacies (<20 % for each service). The acceptance rates among PWID toward currently offered services were high (≥91.1 %). All potential PDHRS were acceptable by most (68–95.3 %) PWID, and correspondingly 67–94.5 % of PWID reported they would use each service if offered.
NPSS from pharmacies provided many PWID in Liangshan with new syringes. However, disposal of used syringes was problematic. At the time of investigation, half of 16 assessed PDHRS were already available in pharmacies in Xichang. PWID were ready to use all the potential PDHRS and14 of 16 PDHRS were feasible to provide. HIV testing kits may be available in pharmacies in the future. Many pharmacy-delivered harm reduction services are feasible and acceptable among PWID in Xichang, China.
The first indigenous human immunodeficiency virus (HIV) cases in China were reported among heroin users in the Yunnan province in 1989 . The overall HIV prevalence (0.058 %) in China remains low, but HIV prevalence among people who inject drugs (PWID) remains high . Due to country-wide responses [3–6], by the end of 2011, Methadone Maintenance Treatment (MMT) (738 clinics covering 13.3 % of the total PWID) and Needle Exchange Program (NEP) (over 900 sites delivering more than 12 million clean syringes annually) have been scaled up in China [4, 7, 8]. Syringe distribution rates (per PWID per year) in China are greater than the global average, including levels in the United States and Russia . HIV prevalence among PWID has been decreasing from 12.0 % in 2005 , 9.3 % in 2009 to 6.4 % in 2011 . In certain areas, such as Liangshan Yi Autonomous Prefecture (Liangshan), Sichuan province, sharing syringes and other injection equipment are still common among PWID [5, 6, 9]. Between March 2004 and December 2012, HIV prevalence among PWID from 11 methadone clinics in Liangshan was found to be 25.4 % .
In 2012, China accounted for approximately 20 % of the global numbers of PWID [10, 11]. Sichuan province ranked 5th in the number of PWID in China ; most are from Liangshan [12, 13]. Liangshan has been part of the major drug trafficking routes in China for more than 100 years, and heroin use is common in Liangshan . HIV incidence in Liangshan increased dramatically, accounting for 81.5 % of the total HIV/AIDS cases in the past 5 years . According to the Asian Epidemic Model, PWID accounted for 52.3 % of the HIV infections in Liangshan in 2013, and are anticipated to be responsible for 39.1 % by 2020 .
Providing sterile syringes to PWID is a cost effective method of HIV prevention . NEP and pharmacies are the major sources of sterile syringes . Yet perceived discrimination , internalized stigma , and lack of stigma management strategies  impede PWID from using formal health services such as NEP [20, 22, 23]. Internationally, community pharmacies have been providing services such as non-prescription syringe sales (NPSS), HIV-testing, vaccinations, educational materials, and coupon syringe programs. Other services are potentially available in pharmacies, such as providing methadone, naloxone for overdose treatment, safer injection training programs, containers to dispose of used syringes, on-site disposal, testing for hepatitis, and directly observed therapy for PWID [18, 21, 24–38]. However, PWID have reported problems accessing available harm reduction services. Refusals to sell syringes and demands for picture identification or prescriptions have been documented even when purchasing syringes is legal and there is no official requirements for providing identification or a prescription [18, 29, 30, 35–37].
In China, syringes are considered medical devices. Pharmacies that sell syringes are required to obtain a “Medical Devices Operation Enterprises permit”, which is issued by the provincial bureau of the Food and Drug Administration (FDA) and supervised by the Prefecture FDA . In Guangxi Province, distribution of pharmacy vouchers for syringes, ampoules of sterile water for injection, and condoms has been previously tested . A survey among 324 PWID from detoxification centers in Yunnan Province documented that their major sources of syringes were pharmacies and health clinics . Between 2008 and 2011, NEP among 19 counties in Yunnan had been implemented at pharmacies, clinics, and through peer educators .
NPSS to PWID in Liangshan have not been reported in previous literature, and it was unclear whether PWID would utilize potential PDHRS. Xichang, the capital of Liangshan, has a population is more than 600,000 . In 2012, the official estimated number of PWID was 2250, and drug use contributed to 60 % of HIV infections . The HIV prevalence among PWID in Xichang was found to be 11.3 %  in 2002, 17.8 % in 2004 , and 18.0 % in 2012 . There is one MMT clinic, three MMT outpatient service sites, and three NEP sites. In 2012, there were more than 400 pharmacies. The goal of the present study was to examine the feasibility of a range of PDHRS for PWID in Xichang.
This study was a cross-sectional study design, and the protocols were approved by both institutional review boards (IRBs) from Johns Hopkins Bloomberg School of Public Health (JHSPH) and the West China School of Public Health (WCSPH). The survey was developed as part of a multisite study on the feasibility of using pharmacies for PWID’s health services . The protocol and questionnaire were initially written in English. The questionnaire was translated into Chinese, reviewed both by the US and China study team, and piloted. The survey took approximately 30 min to administer. The local collaborator, Xichang Skin Disease and Prevention Center (XSDPC), is a government agency responsible for HIV/AIDS prevention and control. The research team selected Xichang methadone clinic and detoxification center to recruit eligible PWID. The study inclusion criteria for PWID were: 1) 18 years of age or over and 2) had injected drugs within the past 30 days. From April to May, 2012, investigators from WCSPH and staff from XSDPC were trained as interviewers and conducted face-to-face structured interviews. Snowball sampling methods were used. After completing their interviews, PWID were encouraged to inform other PWID about the study. A total of 403 PWID were recruited from Xichang detoxification center (66.7 %), MMT clinic (15.6 %), communities (7.4 %), MMT outpatient service sites (6.7 %), and rehabilitation center (3.5 %). As participants volunteered for the study and came to the clinics for the interviews, response rates could not be calculated.
Before completing an interview, eligible participants provided informed consent, and 50 yuan (~USD 8) compensation was provided after completing the surveys. Condoms and safe injection supplies were provided as well as appropriate referrals. The survey questions included demographic characteristics, self-reported HIV status, methods of obtaining and disposal of syringes, experiences of syringe services in pharmacies, and the perceptions and potential utilizations of 16 potential PDHRS. The 16 PDHRS included: printed materials about HIV, Hepatitis C, and sexually transmitted infection(STI) risk reduction; blood pressure check; vaccinations for Hepatitis A and B; information about how to prevent abscesses; overdose medication (naloxone); sharps container to dispose of syringes; a written medical, drug treatment, and social service referrals; free condoms; HIV testing; training or information about how to inject safely; training or information about preventing overdoses; syringe exchange; disposal of used syringes; directly dispensing methadone; and free syringes. The response options toward potential PDHRS were binary (yes or no).
SPSS 22.0 (IBM, USA) was used for analyses. For univariate analysis, range and median for interval variables and frequencies for nominal variables were conducted. Fisher’s exact test was used for comparing the frequencies of receiving and giving used syringes among PWID and P < 0.05 as a level of statistical significance.

In the past 30 days, 2.7, 19.4, and 77.9 % of PWID, respectively reported “always”, “at least once”, and “never” using a used syringe; 3.5 % “always”, 25.3 % “at least once”, and 71.2 % “never” passed their syringe to someone else to use after they had used it. It is interesting to note that PWID reported receiving fewer used syringes than they distributed (Fisher’s exact test, p < 0.01).

At the time of this study, government funded detoxification center, MMT, and NEP services were available, but no government funded HIV prevention funds provided to pharmacies for harm reduction services in Xichang. The first available harm reduction service reported in this sample of PWID was HIV testing, which occurred in 1994, 5 years after the first large national HIV outbreak among PWID in Yunnan . As almost all (95.8 %) PWID had been in prison or jail or forced drug treatment where HIV testing is mandatory, it was expected that over 95 % should have been tested. However the self-report HIV testing rate was only 71.0 %. Therefore, it is probable that HIV positive status was under-reported . In this study, syringe sharing was lower than previously reported , which may be due in part to country-wide responses to HIV by increasing the levels of syringe distribution [3–6, 9].
Though most PWID (>90 %) were recruited from harm reduction sites, pharmacies, rather than these sites, were the main source of obtaining syringes. Pharmacies appear to be a critical and highly accessible source of syringes, although 18.6 % of participants reported that they had experienced a refusal to their request to purchase syringes. Almost all PWID did not dispose of their used syringes safely . Though eight of 16 PDHRS were available for PWID, but only at low level (<20 %), the acceptance rates were high, and PWID were highly supportive of additional PDHRS.
Not surprising, free syringes from pharmacies are not currently offered. The success of NPSS is as part of the pharmacy business. Although NPSS from pharmacies were common, operation hours created a significant barrier against purchasing syringes. Perceived discrimination may also prevent PWID from purchasing syringes from pharmacies . In other studies in Yunnan, PWID reported pretending to buy OTC drugs when purchasing syringes to avoid discrimination [41, 42]. In this study, most PWID wanted to buy syringes from pharmacies where they buy OTC or prescription drugs, but less than half chose pharmacies at the same neighborhood/region where they live. These findings suggest that fears of discrimination and stigma either from pharmacists/pharmacy staff or from others in their neighborhood are potential barriers against obtaining syringes from pharmacies. Prior research has also found that hostile service environments may increase the odds of improper syringe disposal .
Free printed materials about HIV, Hepatitis C, and STI risk reduction and free blood pressure checks that are commonly used to promote business ranked the first and second most frequently used PDHRS. The other six PDHRS targeting high risk populations were provided by less than 3 % of pharmacies. Future pharmacy based harm reduction interventions could begin with services that are mutually beneficial to pharmacies and PWID. Naloxone  would be an example of such service.
There were eight categories of services not currently offered in pharmacies in Xichang. Lack of “free condoms”, “free syringes”, and “exchanging used syringes for new ones” is probably linked with business concerns of reduced revenue for these services [18, 29–31, 35–37]. Legal considerations  may contribute to the lack of HIV testing [48–50], vaccinations for Hepatitis A and B , syringe disposal , and directly dispensing methadone [47, 52]. The dearth of “a written drug treatment referral” may be due to lack of “time” and professional training for pharmacists [18, 29–31, 35, 37]. Financial concerns could be resolved by reimbursements, similar to pharmacy vouchers, for syringes . At the time of investigation, HIV testing was only available in medical facilities [48–50] not pharmacies. After approval from China FDA, HIV test kits may become available in pharmacies . Currently, methadone clinics are only government administered . As an alternative, pharmacies in areas with high numbers of PWID could dispense methadone [7, 52, 53], which may make MMT more available and cost-effective than only dispensing at national clinics  where discrimination and stigma have been documented [19, 20, 22, 23, 54]. Similarly, used syringes could be disposed at pharmacies . In order to offer greater harm reduction services, pharmacy staff need training to improve their knowledge and skills (including drug treatment referrals) and enhanced sensitivity toward PWID. Due to easy access at community health centers [49–51], it is not necessary to provide vaccinations in pharmacies.
The limitations of the current study should be noted. All data was based on self-reports. Snowball sampling was used, and the participants were recruited primarily from harm reduction sites limiting the generalizability of the findings. Future studies should recruit PWID from the general communities. Respondent driven sampling could be applied . Further studies should also examine barriers for pharmacies to provide harm reduction services.
Although community pharmacies have been providing services to PWID in many countries and in parts of China, comprehensive PDHRS had not been reported in Liangshan where HIV is prevalent and the major route of HIV infection is injection drug use. The findings indicated that NPSS from pharmacies provided most PWID with new syringes, but disposal of used syringes was problematic. At the time of investigation, 8 of 16 services were already available. PWID were interested in using all the potential PDHRS, if available. Of the 16 PDHRS, 14 were feasible to be provided if pharmacies benefited financially from providing such services. Future harm risk reduction programs should provide the reimbursements for pharmacies and training for pharmacists.
