Opinions of West Texas pharmacists about emergency contraception

Abstract

Background

The pharmacist’s role in dispensing emergency contraception (EC) has become controversial due to the intersection of personal and professional ethics. Therefore, to examine the issue of EC availability, we surveyed a sample of West Texas pharmacists. West Texas is a religiously and politically conservative region where no methods of EC have been made available.

Objective

to survey a sample of pharmacists in West Texas about their experience, beliefs, and knowledge of EC both before and after a presentation of the current literature about EC.

Methods

We asked a convenience sample of 75 pharmacists about their experience, beliefs, and knowledge of EC both before and after a presentation of the current literature about EC.

Results

Sixty-four (85%) pharmacists agreed to complete the study questionnaire. None carries EC in his/her pharmacy, and scientific understanding of EC was generally poor. Fourteen percent stated EC conflicts with their religious views, 17% considered it a method of abortion, 11% would not be willing to fill an EC prescription written by a doctor. 58% would be willing to offer EC over the counter. The presentation encouraged more to offer it over the counter, but in general did not significantly change their beliefs.

Conclusion

Our sample of West Texas pharmacists demonstrated very little experience with, a general lack of knowledge about, and some personal and religious objections to EC.

INTRODUCTION

Hormonal emergency contraception (EC), also called post-coital contraception, is used after unprotected intercourse to prevent pregnancy. Recent controversy has stemmed from news reports of pharmacists refusing to dispense EC due to their right to exercise their conscience to refuse to dispense a prescription in morally objectionable situations.1,2,3 Some of the controversy may be a result of that fact that the mechanism of action of EC is not precisely known.4 While the prevailing evidence suggests that it prevents conception by preventing or delaying ovulation5,6,7 there is some evidence to support that it may also work to prevent implantation.8,9

This controversy has caught the attention of professional organizations,10 pharmacists,11 ethicists2, and legislators.12 Physicians,13 midwives,14 and patients15,16 have been surveyed regarding their beliefs, and reports have been generated about pharmacist participation in statewide collaborative drug therapy agreements in Washington and Minnesota.17,18 Yet we are aware of only one survey of the knowledge and beliefs of American retail pharmacists. The survey was from New Mexico, and EC was already widely available at the time it was conducted.19

We undertook our survey in order to ascertain EC beliefs and knowledge from a group of pharmacists in West Texas, which is a religiously and politically conservative region where EC is not available. Lubbock county has approximately 207,000 residents. 27% are Hispanic or Latino, and 9% are black. Another 600,000 West Texas residents live in the surrounding counties.20 We are not aware of any pharmacies in Lubbock county or in the surrounding West Texas counties that carry Preven or Plan B (proprietary forms of EC).

Our objective was to survey a sample of pharmacists in West Texas about their experience, beliefs, and knowledge of EC both before and after a presentation of the current literature about EC.

METHODS

This study was approved by both the West Texas Pharmacists Association (WTPA) and the Texas Tech University Health Sciences Center Institutional Review Board. The WTPA is a professional organization with 400 to 500 members. Its membership includes approximately 20% of the pharmacists practicing in West Texas. The average age of its members is approximately 50 years old, and 85-90% of members are male. The majority of members practice in independent retail pharmacies.

One of the authors (GS) was invited to give a presentation on EC, the biologic studies examining its mechanism of action, and the clinical studies examining its efficacy and safety at the WTPA meeting on September 22, 2003. Prior to and after listening to a 40 minute presentation of the current literature on EC and with informed consent, all 75 attendees of the presentation were given a written survey assessing demographic variables and their experience with, knowledge of, and beliefs about EC. The survey was created by the authors. Participation in the survey was anonymous and voluntary. Demographic variables and answers to the survey questions were calculated using simple frequencies. We tested for differences in the proportions of respondents’ answers before and after the talk by conducting chi-square analyses. Because the surveys were completed anonymously, we did not have the ability to match pre- and post- answers.

RESULTS

Sixty-four (85%) of the 75 pharmacists who attended the WTPA meeting completed the questionnaire. Table 1 lists characteristics of the 64 respondents, who had a mean age of 60 (range 36- 86; mean age of male respondents was 64; mean age of female respondents was 47). 77% of our respondents were from Lubbock’s surrounding counties, i.e.: primarily rural areas of West Texas. Of the 11 respondents who stated their practice is ten or more miles from the next pharmacist, 10 (91%) work in independent retail pharmacies and 1 (9%) gave no response. Of the 52 who stated their practice is less than ten miles from the next pharmacist, 21 (40%) work in independent retail pharmacies, 15 (29%) work in chain retail pharmacies, and 16 (31%) work in hospitals or other institutions. One gave no response.

None of the 64 respondents carries any form of proprietary EC (in the form of Preven and Plan B) in his or her pharmacy, has been asked by either a patient or a physician about EC in the previous 12 months, nor have they ever filled a prescription for EC. Yet when asked about their exposure to potential candidates for EC, 8 (13%) had seen a woman reporting a recent rape, 15 (23%) had seen a woman reporting a broken condom, and 60 (94%) had seen a woman report missing some oral contraceptive pills. Five respondents (8%) worked for a pharmacy with a policy on the provision of post-coital contraception with a prescription, even though EC was not carried.

Table 2 summarizes the knowledge of our surveyed pharmacists before the talk. Table 3 summarizes the beliefs of our surveyed pharmacists before and after the talk. Before the presentation, seven of the 45 that would fill a prescription written by a physician would not give it OTC. Seven out of the 14 not willing to provide EC over the counter (OTC) indicated a religious objection. The other 7 had no religious objection to EC. All of the 45 who did not object to EC on religious grounds were willing to fill EC prescriptions written by a physician. 39 of these 45 would also give EC OTC. Only 73% of respondents indicated they would give EC to a rape victim. The presentation did not significantly change their beliefs with exception of an increased willingness to provide EC OTC (p=0.04).

DISCUSSION

This is the first survey that we are aware of that has asked pharmacists in a region where EC is not widely available about their experience with, knowledge of, and beliefs about EC. These pharmacists were generally uninformed about EC and did not carry EC. Many women they saw were candidates for EC but never asked the pharmacist about it. Despite West Texas’ lack of EC availability, it is not unreasonable to assume that these pharmacists have been exposed to these controversies in the local media. It is interesting that five respondents (8%) worked for pharmacies with a policy on the provision of post-coital contraception but did not actually carry EC. It would have been interesting to hear specific information about those policies, as this dichotomy by itself is an indication of conflicting values.

A survey of pharmacists in New Mexico, where EC is more widely available, generally showed positive attitudes and beliefs about EC.19 Those that participated in a state-approved EC prescribing training program had higher knowledge scores about EC. A survey of Thai pharmacists also showed generally poor knowledge of EC.21 A survey of United Kingdom pharmacists revealed that despite it’s a wide availability, only 44% had received training in EC.22

Fourteen percent of our pharmacists said that EC conflicts with their religious views, and we were not surprised that our presentation did not significantly alter their beliefs. Pharmacists who object to dispensing an EC prescription believe they have the right not to fill prescriptions that violate their beliefs.1 Yet others feel this type of conscientious objection to fill a valid prescription is not in a patient’s best interest or safety.23 In Washington State, where pharmacists are allowed to enter into collaborative prescribing agreements with physicians, the majority of surveyed pharmacists indicated that they derive a high satisfaction from providing EC.17 The most common reason given was “meeting patients’ needs.” Six states currently protect a patient’s right to receive EC from a pharmacist, and four states currently allow a pharmacist to refuse to fill an EC prescription.24 In 2005, sixteen states introduced some type of legislation to permit either pharmacists or pharmacies to refuse to fill a valid prescription based on personal beliefs.2,25 Both the American Society of Health System Pharmacists and the American Pharmacists Association endorse referring patients to other pharmacists or pharmacies in cases where filling the prescription conflicts with a pharmacists religious or moral values.1,26

We were surprised that the presentation significantly increased the percentage of pharmacists who would provide EC over the counter. Minnesota also has a collaborative prescribing agreement, but about half of the surveyed pharmacists had reservations about dispensing EC over the counter. Cited reasons included discouraging regular contraceptive use, personal or moral objections to EC, patient safety, lack of knowledge about EC, and liability concerns.18

EC is available OTC in India, Norway, and Sweden.

Because EC is more effective the sooner it is used27 and because privacy issues discourage some women from visiting a physician,28 some have theorized that OTC access to EC would prevent more unwanted pregnancies than if it was only available by prescription.29 One randomized trial demonstrated that pharmacy access (specifically, the ability to obtain EC from a pharmacy without prescription) did not decrease the pregnancy rate, nor did it increase sexual activity.30 This contradicts those who have suggested that wider availability of EC will encourage adolescents to practice risky sexual behavior31 or discourage physicians from screening for sexually transmitted diseases.32 The FDA has approved EC for “behind-the-counter” distribution to women 18 or older.

Our study is limited by the fact that we surveyed a convenience sample of pharmacists who may have been influenced by a recall bias regarding patient encounters. Furthermore, our survey sample may not be representative of the entire population of West Texas pharmacists. Our survey was not tested for validity or test-retest reliability. Many of our calculations did not reach statistical significance. A larger survey group might give more power to our study.

Our survey also had many non-answers to several questions. Did the pharmacists who did not answer the knowledge questions (i.e.: the 31% who did not know the difference between Preven and Plan B) prefer not to answer, or was that an indication that they did not know the correct answer? We also had many non-answers to the more sensitive questions regarding beliefs. For example, when asked if they would be willing to provide OTC EC, 20% did not answer. Did these 13 object to the question? Did they not understand the question or believe the issue to be more complex than stated? Were they just unsure about the implications of selling EC over the counter? We only gave them “yes” or “no” choices and will never know.

CONCLUSIONS

We surveyed a sample of pharmacists from West Texas about EC. We found a general lack of knowledge about the biology, safety, and efficacy of EC. Fourteen to seventeen percent of our respondents were opposed to EC in general. Although a presentation did increase the percentage that would be willing to provide EC over the counter, it did not significantly change their beliefs.
