A redesigned follitropin alfa pen injector for infertility: results of a market research study.

BACKGROUND: The purpose of this study was to evaluate patient-learning and nurse-teaching experiences when using a redesigned prefilled, ready-to-use follitropin alfa pen injector.
METHODS: Seventy-three UK women of reproductive age either administering daily treatment with self-injectable gonadotropins or about to start gonadotropin treatment for infertility (aged 24-47 years; 53 self-injection-experienced and 20 self-injection-naïve) and 28 nurses from UK infertility clinics were recruited for the study. Following instruction, patients and nurses used the redesigned follitropin alfa pen to inject water into an orange and completed questionnaires to evaluate their experiences with the pen immediately after the simulated injections.
RESULTS: Most (88%, n = 64) patients found it easy to learn how to use the pen. Among injection-experienced patients, 66% (n = 35) agreed that the redesigned pen was easier to learn to use compared with their current method and 70% (n = 37) also said they would prefer its use over current devices for all injectable fertility medications. All nurses considered the redesigned pen easy to learn and believed it would be easy to teach patients how to use. Eighty-six percent (n = 24) of the nurses thought it was easy to teach patients to determine the remaining dose to be dialed and injected in a second pen if the initial dose was incomplete. Compared with other injection devices, 96% (n = 27) thought it was "much easier" to "as easy" to teach patients to use the redesigned pen. Based on ease of teaching, 68% (n = 19) of nurses would choose to teach the pen in preference to any other injection method. Almost all (93%, n = 26) nurses considered that having the same pen format for a range of injectable gonadotropins would facilitate teaching and learning self-injection.
CONCLUSION: In this market research study with infertile patients and infertility nurses, the redesigned follitropin alfa pen was perceived as easy to learn, easy to teach how to use, and well accepted.

Introduction

Daily injections of urinary or recombinant gonadotropins are often used to treat infertile patients and may include human follicle-stimulating hormone with or without the addition of luteinizing hormone. These gonadotropin products are often self-injected to promote follicular development as part of the treatment plan for assisted reproductive technologies, such as ovulation induction combined with natural intercourse, intrauterine insemination, or in vitro fertilization. At the end of the controlled ovarian stimulation phase with injectable gonadotropins, a single injection of human chorionic gonadotropin may be used to promote final follicular maturation and to trigger ovulation.

The need for daily subcutaneous injections in infertility treatment does not tend to impair treatment adherence, but there is patient anxiety surrounding whether the correct dose has been delivered and the fact that unconscious mistakes can be made.1 To improve compliance with treatment, it is important that devices used for the administration of recombinant human gonadotropins are easy for patients to learn to use, as well as easy for nurses in charge of patient training to teach. Currently, the majority of gonadotropin products are administered via syringes or prefilled pen injection devices, which have been introduced in the last decade to try to improve patient convenience and ease of use.

A key attribute of any injection device is the number of steps required to prepare and administer the injection. Fewer and easier steps are likely to reduce injection errors and to contribute to patient confidence.

The original pen injector for administration of follitropin alfa (recombinant human follicle-stimulating hormone) was modified to include built-in, enhanced, patient-friendly features, including visually improved numbering on the dose-setting dial in a second-generation pen. The third-generation redesigned follitropin alfa pen injector used in this study is a multidose, ready-to-use prefilled pen that incorporates several new and improved features. These features include a dose display window with a magnifying glass lid to enlarge the dosing number, which shows only the selected preset dose, the return of the dose reading to zero after injection of the full prescribed dose, or information on how much residual dose is required with a second pen if the full dose has not been administered, and a fully transparent cartridge container with graduated markings, to assist the user in determining the approximate amount of product left in the pen. The pen is available in three dose presentations of follitropin alfa, ie, 300 IU, 450 IU, and 900 IU. A key feature of the pen is that it offers flexibility in individualization of treatment protocols with a wide range of dose increments, ie, 12.5–300 IU for the 300 IU pen and 12.5–450 IU for the 450 IU and 900 IU pens. Results of the dose accuracy testing of the 900 IU presentation of the redesigned follitropin alfa pen injector, performed in accordance with international standards (EN ISO 11608-1:2000), demonstrated that the pen can accurately deliver a wide range of doses.2

The objective of this market research study was to assess the ease of teaching by fertility nurses on how to use the redesigned follitropin alfa pen injector, as well as the ease of learning to use the pen by infertile patients undergoing ovarian stimulation with gonadotropins.

Materials and methods

This study was conducted in the UK in January–February 2011 (London, Birmingham, Southampton, Manchester, Glasgow, and Newcastle). Patients and nurses were recruited by Insight Research Group, London, UK, based on the criteria outlined below. All participants provided informed consent.

Study participants

Patients eligible for inclusion in this study were women of reproductive age who were either undergoing controlled ovarian stimulation or had previous experience with daily injections of gonadotropin products within the last 6 months, or were injection-naïve with no previous experience with injectable medications but were consulting with a fertility clinic and were about to start gonadotropin treatment for infertility.

Nurses working in infertility centers and responsible for teaching patients undergoing fertility treatment to use self-injection devices (syringes and pens) were also included in the study. Nurses had to teach at least 10 patients in an average month, spend 80% of their working time in infertility clinics and have 3–30 years experience of working in an infertility clinic to be eligible for inclusion.

Training procedures and study questionnaires

Patient-learning and nurse-teaching experiences when using the redesigned follitropin alfa prefilled pen (GONAL-f ®/GONAL-f ® Revised Formulation Female Prefilled Pen, Merck Serono SA, Geneva, Switzerland, an affiliate of Merck KGaA, Darmstadt, Germany, Figure 1) were evaluated in this market research study. Before a moderator presented and demonstrated the operation of the pen injector to the nurses, they completed part of an online nurses’ questionnaire (Appendix 1) pertaining to use and perceptions of existing devices for administering fertility treatment. To ensure consistent demonstration of the pen injector, the moderator followed a script that outlined step-by-step written and diagrammatic instructions. This was also available to nurses as additional guidance in handling the pen. After receiving the verbal and written instructions, nurses were each given a new, unbranded 900 IU demonstration pen, prefilled with water for injection, and were asked to attach the needle, practice removing large air bubbles, and inject 125 IU of water into an orange as many times as required to gain familiarity with the pen injector. Nurses then completed the part of the nurses’ questionnaire on ease of learning. The nurses then repeated the process, training small groups of up to five patients per nurse. The moderator ensured that an accurate demonstration of the pen injector was provided to patients.

The pen barrel and cartridge comprise sections 1–5.

For assessment of acceptance of the redesigned follitropin alfa pen, nurses completed the relevant questions on their questionnaire and patients completed a separate online patient questionnaire (Appendix 2). Each step of the injection process with the pen was assessed to determine both how easy it was to teach and to learn in terms of priming, attaching the needle, reading the dosing scale, setting the dose, pushing the dose setting knob when injecting, and checking that the full dose had been injected. Respondents also evaluated how easy it was to determine the remaining dose to be dialed and injected with a second pen if the initial dose was incomplete, readjust the dose if needed, and remove the needle. Nurses and treatment-experienced patients also compared the attributes of this pen injector with the self-injection devices that they currently taught or used, based on recall. The entire process of instruction, practice, and completing the questionnaire took approximately 70 minutes for nurses and 40 minutes for patients.

The redesigned prefilled follitropin alfa 900 IU demonstration pens were supplied by the manufacturer. All materials were new before assessment by each patient/nurse.

Statistical analysis

Data from nurse and patient questionnaires are presented using descriptive statistics. Scales rating key performance indicators used a 5-point scale where 5 was the best and 1 was the worst possible outcome. Questions on preferences and advantages did not use rating scales and are quoted as a percentage of participants who provided each response.

Results

Seventy-three infertile women of reproductive age and 28 nurses who had worked for 3–30 years in an infertility clinic were enrolled in this study; the numbers of patients and nurses recruited from each city are shown in Table 1.

All of the patients/nurses participated in the training and completed all the sections of the questionnaires that were relevant to their experiences, ie, self-injection-naïve patients did not answer questions aimed at self-injection-experienced patients.

Patients

The specific aspects of the redesigned pen injector that patients considered easy to learn are shown in Figure 2. Eighty-eight percent (n = 64) of patients found the whole process easy to follow and had no trouble learning how to use the pen; 70% (n = 51) found it easy to learn how to set the dose and how to remove large air bubbles before use.

Figure 2

Aspects of the redesigned follitropin alfa pen that patients found easy to learn.

Note: *Top-up dose; remainder of dose to be dialed and injected in a second pen.

In the total patient population, 89% (n = 65) of patients were either “very” or “quite comfortable” with the zero reading on the dosing scale indicating that the full dose had been injected and 88% (n = 64) with pen control when injecting. The flexibility to readjust the dose, if the set dose was too high/low, was seen as an advantage in learning how to use the pen by 85% (n = 62) of patients.

Most (95%, n = 69) patients “strongly/somewhat agreed” that they were comfortable with the number of steps involved in preparing and giving the injection, and 93% (n = 68) believed that using the new pen device would ensure that they set the correct dose and administered it in full when they self-injected at home.

Among the injection-experienced patients, 66% (n = 35) considered that the redesigned follitropin alfa pen was easier to learn to use than their current injection method; the pen performance was rated as “very high” or “high” by 83% (n = 44) of patients for ease of learning to remove a large air bubble, by 81% (n = 43) for attaching the needle onto the pen, by 79% (n = 42) for reading the dosing scale, and by 74% (n = 39) for reading the graduated markings on the reservoir holder. Eighty-seven percent (n = 46) of the injection-experienced patients found it easy to learn how to set the dose, 89% (n = 47) to push the dose setting knob when injecting, 89% (n = 47) to check that the full dose had been injected, 72% (n = 32) to detach and discard the needle, and 81% (n = 43) to determine any remaining dose required with a second pen if the initial dose administered was incomplete. Of these injection-experienced patients, 70% (n = 37) claimed they would prefer to use the redesigned follitropin alfa pen over their current injection device in the future for all their injectable fertility medications (Figure 3).

Figure 3

Summary of device preferences by injection-experienced patients.

The number of patients with previous experience of the Puregon® pen was small (n = 8), reflecting the low number of Puregon pen users in the UK and, therefore, is insufficient to draw any specific conclusions regarding device preference.

Nurses

All nurses agreed that it was easy to learn how to use the redesigned pen and believed it would be easy to teach patients how to use it. Based on ease of teaching, 68% (n = 19) of the nurses would choose to teach the redesigned pen in preference to any other pen or syringe/vial currently available (Figure 4).

Figure 4

Summary of device preference by infertility nurses teaching patients to self-inject.

Regarding aspects of the pen that were easy to teach, 93% (n = 26) of nurses thought it was “very” or “somewhat” easy to teach patients the overall process of self-administering a dose (Figure 5). Compared with other pen injectors, 96% (n = 27) of nurses thought it was “much easier” to “as easy” to teach patients to use the redesigned follitropin alfa pen; 46% (n = 13) thought it was “much” or “somewhat” easier to teach patients to use the redesigned follitropin alfa pen, and 50% (n = 14) considered it was neither easier nor harder. Almost all (96%, n = 27) nurses rated as “very” or “quite” high, the range of possible doses that could be administered (due to a greater number of dosing increments), and 79% (n = 22) were confident that the patient would be able to calculate correctly any remaining dose needed with a second pen if an incomplete dose was injected with the first pen.

Figure 5

Fertility nurses’ opinion of ease of teaching for each of the functions of the redesigned follitropin alfa pen.

Note: *Top-up dose; remainder of dose to be dialed and injected in a second pen.

It was “strongly” or “somewhat” agreed by 93% (n = 26) of nurses that having the same pen format for a range of injectable gonadotropins would make it easier for them to teach patients to self-inject and for patients to learn how to self-inject; 86% (n = 24) of nurses agreed that the redesigned pen would significantly reduce their teaching time with patients, 89% (n = 25) thought it would reduce mistakes when patients self-administered at home, and 96% (n = 27) believed that, given a choice, patients would prefer the same pen format for administering all their injectable gonadotropin products.

Discussion

This is the first study to report patient and nurse opinions on the redesigned follitropin alfa pen for infertility treatment. Patients with infertility, who currently require numerous administration devices to deliver the full spectrum of gonadotropins during infertility treatment,3 found the pen injector easy to use and most patients found the training on use easy to follow. Among the attributes of the redesigned pen, patients rated highly the ease of checking that the full dose had been injected and the flexibility to readjust the set dose. Self-injection-experienced patients generally preferred the redesigned pen over their existing injection devices.

There are several reports that infertile patients find pen injectors simpler and easier to use than other administration methods.1,4–7 In a study of nurse-led training on administration of follicle-stimulating hormone, 123 participants attended training and completed a questionnaire. Of the patients who expressed a preference, 94% preferred a pen device to a reconstitution and conventional needle and syringe method. The most common reasons given for selection of a prefilled pen were that it was considered to be easy to use, had a simple and reliable dosing mechanism, and minimized the chance of making a dosing error.1

Prefilled disposable insulin pen injectors have received positive ratings for intuitiveness, instruction time, ease of use, and acceptance in patient surveys.8,9 Among patients with rheumatoid arthritis, a pen injector for a monoclonal antibody scored well compared with a prefilled syringe in terms of pain and time to inject and was perceived to be easier to use and more convenient.10

All the infertility nurses in this study found the pen injector easy to learn to use and believed that it would be easy to teach patients to use. Most nurses considered that having the same device for a range of injectable gonadotropins would facilitate teaching patients to self-inject and would reduce teaching time. These results are in agreement with those from another study in which pen injectors have been reported to be well received by nurses.11

Patients may use several different administration devices to deliver the full spectrum of gonadotropins during infertility treatment, so there is a need to harmonize the administration devices for infertility. A device that could be used to administer the full range of gonadotropins would have advantages for nurses in terms of teaching time and for patients in terms of learning time. The use of a common device is also likely to reduce administration errors.

A limitation of the present study was that only the redesigned follitropin alfa pen was tested and the answers about the devices that were used currently were based on recall. However, 73% of patients interviewed were self-injection-experienced and had received fertility treatment with injectable gonadotropins in the previous six months. Thus, it is considered that results based on patient recall were unlikely to have biased the patients’ answers. In addition, the study was performed in a viewing facility, was open-label and uncontrolled, and assessed perceived ease of learning and ease of teaching of the pen device rather than use in an actual fertility treatment cycle. Further studies are needed to confirm the findings in clinical practice.

Conclusion

In this market research study with infertile patients and infertility nurses, the redesigned follitropin alfa pen was perceived as easy to learn and easy to teach how to use, and was well-accepted. There was also a high level of confidence among participants that the full dose of gonadotropin had been injected properly and that it was easy to learn how to check that the correct dose had been delivered. Moreover, most nurses considered that a single platform for delivery of the full spectrum of infertility medications that a patient might require during treatment would have advantages for teaching and learning use for administration.
