Patient satisfaction with medication for gastroesophageal reflux disease: A systematic review



Patient satisfaction is increasingly regarded as an important aspect of measuring treatment success in individuals with gastroesophageal reflux disease (GERD).


To review how satisfied patients with GERD are with their medication, and to analyze the usefulness of patient satisfaction as a clinical end point by comparing it with symptom improvement.


Systematic searches of the PubMed and EMBASE databases identified clinical trials and patient surveys published between 1966 and 2009.


Twelve trials reported that 56% to 100% of patients were ‘satisfied’ or ‘very satisfied’ with proton pump inhibitor (PPI) treatment for GERD. Patient satisfaction levels were higher for PPIs than other GERD medications in two trials. The sample-size-weighted average proportion of patients ‘satisfied’ with their PPI after four weeks of treatment in trials was 93% (95% CI 87% to 99%), with 73% (95% CI 62% to 83%) being ‘very satisfied’. In four surveys, the average proportion of patients ‘satisfied’ with their PPI treatment was 82% (95% CI 73% to 90%) and 62% (95% CI 48% to 75%) were ‘very satisfied’. Seven trials found a positive association between patient satisfaction and symptom improvement, and two surveys between satisfaction and improved health-related quality of life. Three trials found that continuous treatment yielded higher rates of satisfaction than on-demand therapy.


More than one-half of patients were satisfied with their PPI medication in trials, and more patients were satisfied with PPIs than other medication types. An association between patient satisfaction and symptom resolution was found, suggesting that patient satisfaction is a useful end point for evaluating GERD treatment success.

La satisfaction des patients est de plus en plus perçue comme un aspect de la mesure de réussite du traitement chez les personnes ayant un reflux gastro-œsophagien (RGO).


Analyser la satisfaction des patients ayant un RGO envers leur médicament ainsi que l’utilité de la satisfaction des patients à titre de paramètre clinique par rapport à la diminution des symptômes.


Grâce à des recherches systématiques dans les bases de données PubMedet EMBASE, les chercheurs ont repéré des essais cliniques et des enquêtes auprès de patients, publiés entre 1966 et 2009.


Douze essais ont indiqué que de 56 % à 100 % des patients étaient « satisfaits » ou « très satisfaits » du traitement du RGO à l’aide d’inhibiteurs de la pompe à protons (IPP). Dans deux essais, les taux de satisfaction étaient plus élevés envers les IPP qu’envers les autres médicaments contre le RGO. La moyenne des patients « satisfaits » de leur IPP après quatre semaine de traitement dans le cadre des essais, redressée selon la dimension de l’échantillon, s’élevait à 93 % (95 % IC 87 % à 99 %), 73 % (95 % IC 62 % à 83 %) étant « très satisfaits ». Dans quatre enquêtes, la proportion moyenne de patients « satisfaits » par leur traitement aux IPP correspondait à 82 % (95 % IC 73 % à 90 %), tandis que 62 % (95 % IC 48 % à 75 %) étaient « très satisfaits ». Sept essais ont établi une association positive entre la satisfaction des patients et la diminution des symptômes, et deux essais, entre la satisfaction et une amélioration de la qualité de vie liée à la santé. Trois essais ont établi qu’un traitement continu suscitait de plus forts taux de satisfaction qu’un traitement sur demande.


Plus de la moitié des patients étaient satisfaits de leur médicament par IPP lors des essais, et plus de patients étaient satisfaits des IPP que des autres types de traitement. L’association avec la satisfaction des patients est un paramètre utile pour évaluer le succès du traitement du RGO.

Gastroesophageal reflux disease (GERD), characterized by troublesome heartburn and/or acid regurgitation (1), is a chronic disease that has a substantial impact on health-related quality of life (HRQoL) (2,3). The patient’s perspective on treatment outcome is increasingly being regarded as an important aspect of measuring the success of treatment for GERD in both clinical practice and research (4).

At an international workshop on symptom evaluation in reflux disease, 93% (26 of 28) of participants agreed on the need for increased emphasis on patient satisfaction as an outcome in treatment trials (5). Furthermore, the United States Food and Drug Administration (FDA) recently issued guidelines supporting the use of patient-reported outcomes in clinical trials (6). It is likely that the FDA guidance will translate into policy in the near future, although there is agreement that HRQoL and patient satisfaction should not be a primary outcome measure in clinical trials (7).

Although an increasing number of studies are measuring patient satisfaction with GERD treatment, there has been no systematic review of the evidence to determine whether patient satisfaction is of use as an outcome measure and in differentiating treatments. The aims of the present systematic review were first to assess how satisfied GERD patients are with their medications and, second, to analyze the value of patient satisfaction as an end point, by comparing it with another measure of treatment success, symptom improvement.


PubMed and EMBASE were systematically searched to identify articles published in English between January 1966 and August 14, 2009, using the search strategy detailed in Figure 1. As additional sources of data, the reference lists of selected review articles were also searched.

Literature search strategy

Study selection

Data were obtained from clinical trials (randomized controlled trials [RCTs] and open-label studies, including those using on-demand treatments) in which patient-reported satisfaction was an outcome. Population-based surveys that included assessment of the proportion of individuals with GERD who were satisfied with their treatment were also selected. The medications searched for included proton pump inhibitors (PPIs), histamine type 2 receptor antagonists (H2RAs), antacids and prokinetics (Figure 1).

Ten clinical trials were excluded for the following reasons: five because the percentage of patients satisfied with treatment or a mean satisfaction score from a questionnaire were not reported; two trials because therapy was used in conjunction with surgery; one trial because satisfaction was not patient-reported; one trial because the data were reported only in the congress abstract and not in the full article; and one trial because the study focused on satisfaction after switching medication. Four patient surveys were excluded because the percentage of patients satisfied with treatment were not reported; one survey was excluded because it focused mainly on switching medication.

The following data were collected from the full-text articles describing the selected studies: study design, participant details (including whether endoscopy had been performed), sample size, details of medication, definition of satisfaction, satisfaction rating scale, and the proportion of satisfied patients or mean satisfaction score.

Definition of satisfaction

Two levels of satisfaction were assessed. Patients were considered to be very satisfied if they reported being ‘extremely satisfied’, ‘totally satisfied’, ‘completely satisfied’, ‘very satisfied’, ‘good’, ‘very good’ or ‘excellent’. Patients were considered to be satisfied if they had reported being ‘very satisfied’ (thus ‘satisfied’ incorporates ‘very satisfied’), ‘satisfied’, ‘quite satisfied’, ‘moderately satisfied’, ‘slightly satisfied’ or ‘somewhat satisfied’, or gave a ‘positive response’ or ‘yes’ when asked if they were satisfied.


Data from five, double-blind RCTs and three open-label trials that reported satisfaction after four weeks of treatment were pooled to calculate the average proportion of patients who were satisfied (weighted according to sample size) with different PPIs. Satisfaction with continuous PPI therapy was compared with satisfaction with on-demand PPI therapy. When trials also involved treatment with an H2RA, this was also analyzed, as were satisfaction scores according to the presence of reflux esophagitis. The relationships between patient satisfaction, reflux symptom relief (improvement) and resolution (complete absence of symptoms), and changes in HRQoL were examined. In addition, data from each of the surveys that met the inclusion criteria were also compared, and the data from four surveys were pooled to calculate the average proportion of patients satisfied with PPI treatment.


Overall, the searches identified 152 articles published between January 1966 and August 2009 (Figure 1). After screening the title, abstract or full text, 11 relevant articles remained, and an additional nine studies were obtained from citation lists. Thus, a total of 20 articles that reported patient satisfaction with GERD medication were included in the present review.

Patient satisfaction with treatment

Clinical trials:

Satisfaction with treatment was an end point in 14 clinical trials involving patients with GERD. Of these, 12 articles reported the proportion of patients who were ‘satisfied’ or ‘very satisfied’ with treatment (Table 1). One-half of the studies (813) started with PPI treatment given on an open-label basis, followed by randomization to on-demand or continuous treatment for patients who had achieved symptom control (defined as the complete absence of symptoms in the previous seven days or mild symptoms on a maximum of one day in the previous seven days) in the open-label arm of the study. One study followed the open-label arm with randomization to on-demand or intermittent treatment (14). One study began with a four-week or eight-week RCT, before progressing to an open-label regimen (15); three studies were only RCTs (1618); and one trial was exclusively open label (19). Two studies reported head-to-head comparisons of satisfaction with different PPIs (ie, studies that used different PPIs in a single, randomized, parallel-group trial) (9,15).

Articles reporting treatment satisfaction as an outcome in clinical trials of medications for GERD

Patient satisfaction scales had between four and seven ordered response categories, except for three studies (8,15,16) that used a ‘positive response’ or a ‘yes’ answer to record patient satisfaction. An additional two studies described the degree of satisfaction in terms of mean scores obtained from a questionnaire (20,21).

All 12 articles that reported the proportion of patients satisfied with treatment assessed satisfaction with PPI therapy. Collectively, 57% to 97% of patients were ‘satisfied’, and 56% to 100% were ‘very satisfied’. In the only two articles reporting satisfaction with H2RA treatment (12,17), 79% of patients were ‘satisfied’, but only 33% to 34% were ‘very satisfied’.

Three studies reported head-to-head comparisons of satisfaction with different PPIs. In the acute phase of the trial reported by Tsai et al (9) patients received esomeprazole 20 mg once daily for two or four weeks. Asymptomatic patients then entered the maintenance phase comparing esomeprazole 20 mg on-demand (n=311) with lansoprazole 15 mg continuous daily treatment (n=311) for six months. After one month, significantly more patients were satisfied with esomeprazole on-demand treatment than continuous lansoprazole treatment (93% versus 88% [P=0.02]). Although the numerical difference of 5% in the proportion of satisfied patients between the two regimens was small, it was statistically significant and translated into a difference between the two PPIs in the time to discontinuation from the maintenance phase because of unwillingness to continue. By six months, significantly more patients were unwilling to continue with continuous lansoprazole treatment than with esomeprazole on-demand treatment (13% versus 6% [P=0.001]) (9).

The second study also had two parts: the first compared treatment with continuous omeprazole 20 mg, lansoprazole 30 mg and pantoprazole 40 mg. Patient satisfaction at four weeks was 79% for omeprazole and pantoprazole, and was 76% in the lansoprazole group (no statistically significant differences among the treatment groups) (15).

In the third trial (18), patient satisfaction at four weeks with rabeprazole and esomeprazole (both 20 mg once daily) was 78%. Although satisfaction with esomeprazole 40 mg once daily was numerically higher (82%), the difference was not significant (P=0.209).

In the pooled analysis of trials reporting satisfaction after four weeks, the average proportion of patients satisfied with their PPI treatment, weighted according to sample size, was 93% (95% CI 87% to 99%). Overall, 73% (95% CI 62% to 83%) of patients were ‘very satisfied’. The average level of satisfaction from three trials with omeprazole 20 mg once daily was 77% (95% CI 61% to 93%) (1517); from two trials with lansoprazole at 15 mg once daily (9) and 30 mg once daily (15) was 84% (95% CI 72% to 95%); from one trial with pantoprazole 40 mg once daily was 79% (15); and from four trials with esomeprazole was 95% (95% CI 92% to 98%) (810,19). However, the studies had varied designs, and only the trial by Mulder et al (15) reported any head-to-head comparisons of the different PPIs; therefore, it was not possible to determine from the pooled data whether there were clinically important differences among the PPIs for the satisfaction end point.

The proportion of patients with reflux esophagitis varied among studies and, in three trials, none of the participants underwent endoscopy (Table 1) (12,14,19). It was not possible to correlate levels of satisfaction with healing of reflux esophagitis because the studies did not provide satisfaction values stratified according to these individual subgroups.

In one study, patient satisfaction with treatment effectiveness was the primary outcome of the maintenance phase (8). Patients with and without reflux esophagitis were treated with continuous esomeprazole 40 mg once daily for two, four or eight weeks. Following this, patients were randomly assigned to esomeprazole 40 mg once daily on-demand or continuous esomeprazole 20 mg once daily for three months. The proportion of patients satisfied with maintenance treatment was similar between patients with reflux esophagitis and those without (88% versus 90%) (8).

Three of the four studies that directly compared long-term (three to six months) continuous treatment with on-demand therapy found that continuous treatment yielded significantly higher rates of satisfaction (Table 1) (8,10,12). Pace et al (10) reported lower levels of patient satisfaction than the other two studies, although these studies varied in methodology: Engels et al (8) reported the proportion of patients who were ‘satisfied’; and Pace et al (10) and Hansen et al (12) reported the proportion of patients who were ‘satisfied’ and ‘very satisfied’. In addition, Engels et al (8) and Pace et al (10) included only patients with mild reflux esophagitis and those without, whereas Hansen et al (12) did not perform endoscopy; therefore, their study may have included patients with moderate and severe reflux esophagitis. In contrast, a fourth trial, which was performed exclusively on patients without reflux esophagitis (11), showed no significant difference between treatment groups in terms of the rate of satisfaction with treatment at six months (on-demand 82% versus continuous therapy 86%).


Eight studies used surveys to assess treatment satisfaction in patients with GERD. The patient satisfaction scales used in three studies had five categories (2224), and one study had 11 categories (25). Four studies used a dichotomous response – a positive or negative response to being ‘satisfied’ or ‘very satisfied’ (2629).

Two studies compared patient satisfaction with prescription medication and over-the-counter (OTC) medication, and reported that patients with GERD were more satisfied with prescription medications than with OTC treatments (27,29). The prescription drugs reported by Bretagne et al (29) were PPIs (69%); antacids/alginates (46%); prokinetics (16%); and H2RAs (5.7%), but the OTC drugs were not specified. The study by Shaker et al (27) did not specify the types of prescription or OTC medication used.

Four surveys specifically reported levels of patient satisfaction with PPIs (2225). On average, weighted according to sample size, 82% (95% CI 73% to 90%) of patients were ‘satisfied’ and 62% (95% CI 48% to 75%) were ‘very satisfied’ with PPI treatment. The highest level of satisfaction was achieved with PPI treatment compared with H2RAs and prokinetics (Table 2). This was illustrated by the largest survey (n=11,064), which was performed in the United States by Crawley and Schmitt (22). They found that 82% of patients were ‘satisfied’ with their PPI treatment and 58% were ‘very satisfied’. The proportions of ‘satisfied’ and ‘very satisfied’ patients were lower for H2RAs (77% versus 46%, respectively) and prokinetics (73% versus 42%, respectively).

Surveys reporting patient satisfaction with gastroesophageal reflux disease (GERD) medications

Relationship between patient satisfaction, symptom resolution and HRQoL

Twelve studies reported on the relationship between patient satisfaction and either symptom resolution or HRQoL. Two articles described validation studies of two different, GERD-specific, treatment satisfaction questionnaires, and showed a significant correlation between increased satisfaction, symptom resolution and improved HRQoL (30,31). The first study used the Treatment Satisfaction Questionnaire-GERD (TSQ-G) to assess 198 patients with GERD (30). The satisfaction subscale of the TSQ-G showed significant correlations with scores obtained on the Gastrointestinal Symptom Rating Scale and Quality of Life in Reflux and Dyspepsia questionnaire (QOLRAD) (r=0.26 to r=0.66 [all P<0.0001]). The second performed an Internet-based survey of 2511 individuals taking PPIs or H2RAs to validate the GERD Treatment Satisfaction Questionnaire (G-TSQ) (31). There were slight but significant correlations between G-TSQ scores and the presence of reflux symptoms (r=0.25 to r=0.43).

Satisfaction with improvement in reflux symptoms was compared in seven of the clinical trials reporting the percentage of patients satisfied with treatment, as shown in Figure 2. Five of these seven trials reported treatment satisfaction compared with both complete symptom resolution and symptom relief (8,9,1618). The other two trials (12,15) reported only the complete absence of symptoms compared with satisfaction. Thus, Figure 2 depicts 15 treatment groups for symptom relief and 24 treatment groups for symptom resolution. A correlation between patient satisfaction and symptom relief is indicated at the aggregated study level (8,9,12,1518). Overall, the proportion of satisfied patients increased as the proportion of patients with symptom relief increased. In most of the treatment groups analyzed (12 of 15), the proportion of patients satisfied with their treatment was higher than the proportion who experienced symptom relief by an average (weighted according to sample size) of 11% (95% CI 2.4% to 18.9%). Similarly, in most of the treatment groups analyzed (20 of 24), the proportion of patients satisfied with their treatment was higher than the proportion who experienced complete symptom resolution by an average (weighted according to sample size) of 10.6% (95% CI 2.2% to 19.0%).

Figure 2)
Comparison of treatment satisfaction with the resolution and relief of symptoms (data from references 8,9,12,1518)

Two studies assessed the relationship between satisfaction and a range of other quality of life factors. Degl’Innocenti et al (19) performed a multiple linear regression analysis to assess the determinants of patient satisfaction with treatment. Higher baseline vitality scores in the QOLRAD, greater severity of heartburn at baseline and greater change in QOLRAD vitality score were associated with higher levels of satisfaction (all P<0.001).

Bretagne et al (29) compared satisfaction in patients with frequent or occasional reflux symptoms (heartburn and/or regurgitation) at baseline and found a negative correlation between the frequency of reflux symptoms and the degree of satisfaction. Compared with individuals with occasional reflux symptoms, significantly fewer patients with frequent reflux symptoms were completely satisfied with prescription treatments (75% versus 64% [P<0.001]), which were primarily PPIs (69% of patients with frequent symptoms versus 37% for occasional symptoms) and/or antacids/alginates (46% versus 55%), and less often H2RAs (6% versus 11%) or prokinetics (16% versus 15%).


Although the treatment of GERD has three main goals – symptom control, the healing of reflux esophagitis and the prevention of complications – symptom control may be the most important from the patient’s perspective. Long-term management is often required to sustain symptom control, which may be continuous maintenance treatment (daily dosing of acid suppressive therapy) or on-demand therapy (with medication taken only on the days that symptoms occur, until the symptoms subside). There is convincing evidence in the literature that PPIs are superior to H2RAs for symptom control and healing of reflux esophagitis (32). PPIs are also effective when given daily or on-demand in patients with GERD without reflux esophagitis and in those with uninvestigated GERD (33).

Patient satisfaction with treatment is a valuable outcome because it is a major determinant of the patient’s willingness to continue taking the required medication. It is influenced by many factors, including treatment regimen, general well-being of the patient, the bedside manner of the physician, and the quality of communication between the patient and their physician (34). The present review has identified an association between overall symptom relief and patient satisfaction, and between patient satisfaction and improvement in HRQoL. Similar associations between treatment satisfaction, treatment efficacy and HRQoL have been observed in other chronic diseases such as diabetes mellitus (35) and osteoarthritis (36).

The correlation between HRQoL and satisfaction is a notable finding of the present review because patient satisfaction can be determined by posing a single question, unlike multidimensional instruments designed to understand treatment effects on HRQoL. Although HRQoL instruments are valuable secondary outcome measures in clinical trials, they are time consuming to administer and, hence, not practical in everyday practice. Instead of using an HRQoL questionnaire, perhaps a single question about satisfaction could be used in addition to questions about the control of specific symptoms.

The present systematic review demonstrates that the highest levels of patient satisfaction with GERD treatment are observed for PPIs compared with other GERD medications. Both of the RCTs that compared PPIs with H2RAs (12,17) showed superior levels of satisfaction with PPIs. No RCTs compared PPIs with prokinetic agents, although the survey data showed that satisfaction levels for PPIs were higher than both H2RAs and prokinetics. This is in agreement with trial efficacy data comparing PPIs, H2RAs and prokinetics reviewed by others (37,38). Thus, this suggests that higher patient satisfaction correlates with the greater acid control provided by PPIs than by other medications.

The data support the concept that when patients achieve complete or near complete control of their GERD symptoms, their satisfaction with treatment is high. Although PPIs were shown to decrease the frequency and severity of heartburn, only one trial specifically investigated whether there was a correlation between patient satisfaction after treatment and the severity of heartburn at baseline (19). This study did indeed find that these two factors were correlated. In addition, one survey documented a negative correlation between satisfaction and the frequency of heartburn and/or regurgitation at baseline (29). However, some patients experienced residual symptoms while on treatment. Moreover, data from several RCTs suggest that symptom control and patient satisfaction are lower with on-demand therapy than with continuous maintenance therapy, suggesting that satisfaction with PPI therapy is reduced in the presence of residual symptoms. This would be a justification for adjusting patient medication, for example, by increasing the dose of PPIs (39,40). Partial response to PPIs may also indicate that factors other than acid reflux are contributing to symptoms. These include functional dyspepsia (41), weakly alkaline or weakly acidic reflux (4244), esophageal hypersensitivity or a combination of these factors (45).

Although surveys can be less reliable sources of data than RCTs, they provide insight into the patient’s perspective of treatment in real-life clinical practice. In surveys, the proportion of patients ‘satisfied’ with PPIs tended to be lower than that reported in trials. This difference suggests that patients with a partial response to PPI treatment are more common in unselected populations than in clinical trials. Adherence may also play a role because trials strongly encourage adherence through intensive follow-up – unlike real-life practice. Adherence has been shown to be related to satisfaction in the management of diabetes mellitus, in which lower adherence (eg, difficulty attending follow-up or taking medications [P<0.001]) was associated with lower treatment satisfaction (46).

The relationship between patient satisfaction and the clinical end point of symptom resolution was also analyzed. A correlation between satisfaction and symptom control and resolution was documented, although the proportion of satisfied patients was approximately 10% higher than either end point. A recent workshop on the study design of GERD trials (7) recommended that the absence or near complete relief of previously troublesome symptoms be used to measure treatment efficacy. The data support that patient satisfaction is also of use in assessing the effectiveness of treatment. One interpretation may be that patients can be satisfied despite the persistence of some symptoms, although this was not analyzed in any detail. Interestingly, the same workshop (7) recommended that a validated measure of patient satisfaction should be considered as a primary outcome measure in on-demand studies.

Although high levels of satisfaction with PPIs were reported in many trials, in some cases, a substantial proportion of patients were ‘not very satisfied’ with their treatment. In real-life clinical practice, as illustrated by the surveys reviewed in the present article, more than one-half of patients were less than completely satisfied with their prescription treatment, and up to one-half of patients who were prescribed PPIs used concomitant OTC remedies to control break through symptoms. This suggests that there is still an unmet need for effective treatment in some patients, which requires further study.

A detailed exploration of the relationship between heartburn scores and patient satisfaction among the studies was limited because no trials specifically stratified patient satisfaction according to this variable. Similarly, symptom relief from PPIs has been demonstrated to be highly predictive of reflux esophagitis healing (47); however, correlations between healing and satisfaction could not be performed in the present review because the proportions of patients satisfied after treatment were not described separately for different grades of esophagitis at baseline.

Most of the included studies did not use validated treatment satisfaction questionnaires, although the face validity of many of the instruments used was high. Validated questionnaires to measure patient satisfaction with GERD treatment are now available (30,31), and use of these in future studies of GERD treatment would enable comparison among studies and further pooling of data for meta-analysis.

The present review had several limitations. The studies used inconsistent thresholds for the severity of GERD symptoms at baseline, although most studies used a baseline severity of at least two to four episodes of heartburn per week. There was also variation among studies in the methods used to measure patient satisfaction. Hence, these differences among studies are described in the review and the data were interpreted with this caveat in mind. In addition, the methods used to measure satisfaction in the studies are likely to result in substantial acquiescent response bias (tendency of individuals to agree with questions), particularly in older respondents, those with less education and those in poorer health (48). The use of attitude response scales (such as ‘very satisfied’ to ‘very dissatisfied’) skews individual responses to satisfaction questions and inflates reliability estimates (48). Patients could also interpret the word ‘satisfaction’ variably, reducing the comparability of the results. A study by Vakil et al (49) indicated that symptom questionnaires using continuous rather than binary variables were easier for patients to understand. It was suggested that terms should be more descriptive, for example, ‘satisfactory relief’ could be replaced with ‘at least partial relief’. Hence, as used in three of the studies (8,15,16), a ‘positive response’ to assess levels of satisfaction may have been less clear to the patients than the use of rating scales. Future studies that use multi-item scales that include balanced positively and negatively worded items may increase score variability and reliability in satisfaction research because they are subject to less acquiescent response bias than studies using attitude response scales (48).

The FDA has recently finalized guidance for the development of instruments measuring patient-reported outcomes for use in clinical trials to support label claims (6). The guidelines emphasize the importance of patient input and incorporating patient feedback in the development of questionnaires and reflect the increasing prominence of assessing the patient experience with treatment. Furthermore, compared with patients, physicians tend to overestimate the benefit of PPI treatment in GERD (50). Thus, assessing patient satisfaction with treatment should enable a more comprehensive understanding of disease and treatment response than the traditional reliance on objective disease markers, particularly in patients with GERD without reflux esophagitis because the response to treatment is the main outcome measure.

Insight into patient satisfaction may be particularly valuable when the primary outcomes of clinical trials are similar for two treatments. The present systematic review has shown that patient satisfaction correlates with symptom resolution, a primary outcome of clinical trials, and with HRQoL, a secondary measurement of therapeutic success. It would be of great interest for future studies to report how patient satisfaction relates to other clinical end points, such as patient satisfaction individually reported according to the healing of reflux esophagitis, prevention of relapse and adverse effects, in additon to more studies examining satisfaction and changes in individual symptoms such as heartburn frequency and severity.


The patient’s evaluation of their treatment is becoming increasingly important to medical care, particularly for the management of chronic disease. Future research, with a focus on uniformity in the measurement of satisfaction, and further investigation into the relationship between satisfaction and other clinical end points, could contribute to improved patient care and long-term treatment success.
