Background
In line with developments toward patient-centered care, patient satisfaction is increasingly being recognized as an important outcome measure1 and indicator of hospital quality.2 Measuring patient satisfaction next to quality of life (QoL) may be useful to identify potential areas of improvement.3–5 Higher patient satisfaction has been associated with better treatment compliance, a better doctor–patient relationship, and even improved survival in patients with cancer.6–9
Patient satisfaction is especially relevant in cancer care because of the limited survival, which is characterized by intense and complex treatments associated with frequent hospital visits, adverse events, and (re)interventions. This is particularly true in patients with pancreatic and periampullary cancer, which are among the deadliest cancers.10–12 Up to 80% of patients with pancreatic cancer are diagnosed with nonoperable, locally advanced, or metastatic disease. Although new systemic therapies have shown significant survival benefits in recent years, they increase the risk of severe toxicity.10,13,14 A minority of patients are eligible for surgical resection, which provides a 5-year survival rate of 25% if combined with adjuvant chemotherapy. However, again, both pancreatic surgery and adjuvant treatment are accompanied by high complication rates.10,15 Because of the complex treatments and limited survival, patient satisfaction and QoL are particularly important in the care of patients with pancreatic and periampullary cancer.16
QoL may be influenced by characteristics of the healthcare organization, the patient, and the disease itself.17,18 The exact relationship between patient satisfaction and QoL is unclear. Therefore, this study aimed to assess patient satisfaction with pancreatic and periampullary cancer treatment and its relationship with QoL. In addition, we aimed to identify potential clinicopathologic factors that have a relationship with patient satisfaction. We hypothesized that patients treated in the palliative setting would display lower satisfaction with care than those treated in the curative setting. Our findings will inform healthcare providers about patients’ needs and expectations during the treatment of pancreatic and periampullary cancer and provide options to improve patient satisfaction.
Methods
Patients
A prospective cohort of 100 patients with newly diagnosed pancreatic or periampullary cancer in June 2015 through April 2016 was enrolled from 3 Dutch pancreatic centers: Amsterdam UMC, Academic Medical Center (Amsterdam); Catharina Hospital (Eindhoven); and Erasmus Medical Center (Rotterdam). This study was part of a pilot study of the Dutch Pancreatic Cancer Project (www.pacap.nl) performed by the Dutch Pancreatic Cancer Group (www.dpcg.nl) to investigate patient-reported outcomes.19 Patients received either curative or palliative treatment as defined later. Patients returning the baseline questionnaire after treatment initiation were excluded, as were those who were not fluent in Dutch or could not complete the questionnaires for mental reasons. For measurement of the QoL and satisfaction with care questionnaires, a waiver was obtained for the informed consent procedure from the Amsterdam UMC, Academic Medical Center Institutional Review Board.
Patients were approached for participation within 1 week after diagnosis. Patients could choose to complete an online or paper questionnaire.20 Automated reminders were sent in case of nonresponse. Patients who did not return the follow-up questionnaire after a reminder were contacted by telephone and asked to complete the questionnaire over the telephone (L.B. van Rijssen). Deceased patients were excluded from the calculation of questionnaire return rates.
Questionnaires
Patients completed the Dutch versions of the EORTC cancer in-patient satisfaction with care questionnaire (IN-PATSAT32) and the EORTC Core Quality of Life Questionnaire (QLQ-C30) before treatment and 3 months after inclusion. The IN-PATSAT32 measures patients’ self-perceived satisfaction with care via 32 items that are categorized into 11 multi-item and 3 single-item domains.21 These include measures of doctor and nurse technical skills, interpersonal skills, information provision, and availability; satisfaction with other hospital staff members’ kindness and helpfulness, interpersonal skills, and information provision; exchange of information within the care team; waiting time; hospital access; hospital comfort; and overall satisfaction with care. The scoring procedure for the IN-PATSAT32 module generates a score of 0 to 100 for each (single-item and multi-item) domain. A higher score reflects a higher level of satisfaction.
The QLQ-C30 measures QoL in patients with cancer via 30 items that are categorized into 9 multi-item domains and 6 single-item domains.22 These include 5 functioning scales (physical, role, cognitive, emotional, and social), 3 symptom scales (fatigue, pain, and nausea and vomiting), a global QoL scale, and 6 symptoms commonly reported by patients with cancer (dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties). The scoring procedure for the QLQ-C30 also generates a score of 0 to 100 for each (single-item and multi-item) scale. A higher score for a functioning domain and global QoL represents a better level of functioning. A higher score for a single-item or multi-item symptom domain suggests a higher level of symptoms.
Clinical Data and Definitions
Sociodemographic and clinical data were retrieved from the relevant medical charts at the participating centers. Extracted baseline characteristics were age, sex, education level, ECOG performance status, histopathologic diagnosis (occasionally omitted if patients desired no additional treatment or no pathologic confirmation was available), treatment type, and starting date of treatment. Curative treatment was defined as a pancreatic with curative intent. For patients in good postoperative clinical condition, adjuvant chemotherapy was offered. Palliative treatment was defined as any palliative systemic treatment of metastatic or locally advanced pancreatic or periampullary cancer. The start of treatment was defined as upfront surgery or chemotherapy initiation.
Statistical Analysis
Data were analyzed using SPSS Statistics, version 21 (IBM Corp). Normally distributed continuous data were presented as means with standard deviations, and nonnormally distributed continuous data were presented as medians with interquartile ranges. Categorical data were presented as frequencies with percentages. IN-PATSAT32 and QLQ-C30 scores were expressed as means with standard deviations and compared with the corresponding baseline score using paired t tests and Wilcoxon tests as appropriate. Cronbach’s α was calculated when possible to evaluate each multi-item scale’s internal consistency. Following Osoba et al,23 a change of 10 points on IN-PATSAT32 score was considered clinically meaningful. Only clinically meaningful changes in IN-PATSAT32 scores were reported. A change of 10 points in QLQ-C30 scores was considered clinically meaningful, wherein a change of 5 to 9 indicated a small difference, 10 to 20 a moderate difference, and >20 a large difference.23 Mean differences in IN-PATSAT32 scores were compared using unpaired t tests between patients treated with curative intent and those treated with palliative intent. Sensitivity analysis was performed, excluding patients with diagnoses other than pancreatic or periampullary adenocarcinoma (n=8). Standard multivariable linear regression was used to identify predictors of general satisfaction with care scores after treatment. Included in the regression analysis were clinical variables, the QLQ-C30 score for global QoL, and all 5 functioning scales. QLQ-C30 symptom scales were omitted because it was believed that for the purpose of this study, these were sufficiently reflected in the physical functioning scale. Variables with a P value <.20 in univariable analysis were entered into the multivariable model. Outcomes of the multivariable analysis were reported as β regression coefficients with the corresponding 95% confidence intervals. A P value <.05 was considered statistically significant.
Results
Patients and Characteristics
Mean age of the cohort was 66 years and 61% were men. One patient died of severe cholangitis shortly after inclusion and did not complete any questionnaires. Median time between treatment initiation and the follow-up questionnaire was 13 weeks. Six patients (6%) completed the baseline questionnaire after treatment initiation (range, 2–21 days after start of treatment) and were excluded. Therefore, 93 of 99 patients (94%) completed the baseline questionnaire and were available for analysis, and of these, 71 (76%) completed the follow-up questionnaire. During follow-up, 8 patients died, 8 declined further participation, and 6 were lost to follow-up. A flowchart depicting patient accrual is shown in Figure 1.
Of the 71 patients who completed both questionnaires, 40 (56%) received treatment with curative intent and 31 (44%) received treatment with palliative intent. Among those treated with curative intent, none received neoadjuvant chemotherapy, 13 (33%) received surgery alone, and 27 (68%) received surgery with adjuvant chemotherapy during this study. Baseline patient characteristics are summarized in Table 1.
Baseline Patient Characteristics
Impact of Treatment on Patient Satisfaction and QoL
Satisfaction with care before and after treatment is shown in Table 2. Cronbach’s α coefficients were ≥0.70 for all IN-PATSAT32 domains, indicating good internal consistency. After treatment, reductions of IN-PATSAT32 scores were observed for 3 of 14 domains: general satisfaction with care (from 74.3 to 61.9), satisfaction with the interpersonal skills of doctors (from 73.4 to 63.3), and exchange of information within the care team (from 63.5 to 52.5).
IN-PATSAT32 Scores Before and After Treatment
QoL before and after treatment is shown in Table 3. Global QoL increased from 68.4 to 71.4 (not clinically meaningful). Small changes in QLQ-C30 scores (<10 points) were observed for physical functioning, cognitive functioning, social functioning, and fatigue. Moderate changes in QLQ-C30 scores were observed for role functioning and insomnia, and both were clinically meaningful (≥10 points). Sensitivity analyses excluding patients with diagnoses other than pancreatic or periampullary adenocarcinoma showed satisfaction with care and QoL before and after treatment remained similar to primary results (supplemental eTables 1 and 2, available with this article at JNCCN.org).
QLQ-C30 Scores Before and After Treatment
Treatment Type and Patient Satisfaction
Figure 2A–C show the mean differences in satisfaction scores before and after treatment for patients treated with curative and palliative intent separately. A clinically meaningful reduction (ie, a change ≥10 points, depicted by the dotted lines in Figure 2) in patient satisfaction among patients treated with curative intent was observed for the domains of general satisfaction with care, technical skill of doctors, interpersonal skill of doctors, availability of doctors, availability of nurses, and exchange of information within the care team. A clinically meaningful reduction in patient satisfaction among patients treated with palliative intent was observed for general satisfaction with care.
The mean difference in general satisfaction with care among patients treated with curative intent was −12.5 compared with −12.1 among patients treated with palliative intent. For 6 domains, satisfaction scores were significantly lower among patients treated with curative versus palliative intent. This included the interpersonal skills of doctors (mean [SD], −14.0 [±15.7] vs −4.7 [±20.0]; P=.013), information provision by doctors (−8.9 [±16.3] vs 0.9 [±12.5]; P=.004), information provision by nurses (−8.4 [±11.4] vs −2.7 [±16.0]; P=.02), availability of nurses (−12.8 [±12.6] vs −2.9 [±16.0]; P=.004), exchange of information (−14.5 [±19.0] vs −6.1 [±15.4]; P=.01), and hospital access (−8.1 [±16.6] vs −1.3 [±14.1]; P=.02).
Associations Between QoL and Patient Satisfaction
In univariable analysis, only better cognitive functioning (measured by QLQ-C30) was associated with increased general satisfaction with care (β=0.2; 95% CI, 0.02–0.3; P=.03). Yet, after multivariable analysis, no factors were found to be independently associated with general patient satisfaction (Table 4).
Regression Analysis of Predictors of General Patient Satisfaction With Care After Treatment
Discussion
This prospective multicenter study found that patient satisfaction decreased after treatment of pancreatic or periampullary cancer, whereas global QoL did not. Decreases in patient satisfaction after treatment were found for general satisfaction with care, interpersonal skills of doctors, and satisfaction with the exchange of information within the care team. Somewhat unexpectedly, satisfaction scores decreased more among patients treated with curative intent than among those treated with palliative intent. Our results have important implications for clinical practice and are relevant for those wishing to maintain and even improve patient satisfaction after treatment in their practice.
It was surprising to find decreased satisfaction scores after treatment, because patients may be expected to appreciate treatment of their disease. This expectation has not yet been tested, however, or previous studies did not show a clear relationship. Previous studies have only used cross-sectional assessments of patient satisfaction after treatment of cancer or are heterogeneous in terms of the methods and questionnaires used, impeding cross-study comparisons.24–27
Because the interpersonal skills of doctors and exchange of information within the care team were found to be particularly important determinants of satisfaction with care, our results indicate that communication skills may be important targets for improvement to increase patient satisfaction. This has also been suggested previously.28–30 It is difficult to determine whether communication was truly insufficient in the 3 dedicated pancreatic cancer centers or if this was predominantly the patients’ perception. Furthermore, because of the design of the IN-PATSAT32, it is not possible to determine in hindsight which doctor or doctors (eg, the physician present during pretreatment or posttreatment outpatient visit or the resident during admission) were meant by patients.
Our results may indicate 2 directions for future improvements. First, communication and interpersonal skills need to be improved, specifically with regard to diagnosis and treatment planning, but especially during and after treatment. Second, patient expectations at the outset need to be managed better.
Various studies investigating patient satisfaction have suggested that improved information provision is important.31–36 In fact, information provision is a prerequisite of shared decision-making, which, in turn, has been related to satisfaction with care.8,28,37 Additionally, if patients are well-informed about the risks of treatment (eg, complications, recurrence), coping with complications may be improved.38 This is particularly important because complications after surgery have been shown to decrease satisfaction with care, although such complications are inherent to surgical therapy. Decreases in satisfaction with care may thus be more pronounced in surgically treated patients.39 This may explain why larger decreases in satisfaction with care were observed among patients treated with curative intent (ie, surgical resection) than among those treated with palliative intent (ie, systemic therapy). However, in a study investigating satisfaction among patients treated with curative and palliative intent for upper gastrointestinal cancer, patient satisfaction was independent of (major) treatment-related complications.25 Therefore, a difference in follow-up schemes and practice of surgeons versus medical oncologists may contribute to our findings. The patient–surgeon relationship consists of intense contact in the period immediately after surgery, followed by less contact during follow-up, whereas the patient–medical doctor relationship consists of intense contact during (long-term) follow-up after the postoperative period. Therefore, the effect of specific communication strategies in the pretreatment and posttreatment phases on patient satisfaction should be investigated further in future studies, especially in the curative- and palliative-intent groups separately.
Communication (or rather, a lack thereof) in the posttreatment phase may also contribute to (lower) patient satisfaction. In the Netherlands, as in many countries, multidisciplinary team meetings are mandatory for the treatment of patients with pancreatic cancer.40 Much of the effort of these multidisciplinary team meetings is directed at a rapid diagnostic phase and early treatment initiation.41 Patients spend 1 or 2 days undergoing various diagnostic tests and receive much information, a diagnosis, and a tailored treatment plan. Specialized case managers and oncology nurses guide patients during this time and provide additional information and psychosocial support.42,43 This psychosocial care is important to patients with cancer.44 After treatment, contact with the hospital staff is often reduced, and psychosocial support may rely predominantly on family and friends. In our study, the first questionnaire was sent to patients directly after the (fast-track) outpatient clinic and before treatment. During this time, patients received intensive guidance and psychosocial support. However, after treatment, when patients had to rely mostly on their own psychosocial support system and much less on hospital staff, satisfaction with care was lower. This is especially true in the curative setting, because patients treated with palliative intent may still visit the hospital more frequently than those treated with curative intent (eg, outpatient visits for administration of systemic therapy and potentially for treatment of chemotherapy-related toxicity). In our study, 10 of 15 patients with pancreatic cancer treated with curative intent received adjuvant chemotherapy. However, satisfaction scores among these patients were not significantly higher than among the 30 patients treated with curative intent who did not receive adjuvant chemotherapy (data not shown). Although much effort is already directed at attention to psychosocial problems during follow-up after treatment with curative intent, this may be further optimized by, for example, the use of specific signaling instruments.45
We did not identify associations between QoL and patient satisfaction, a finding that also has been found in previous studies.25,45 Other factors associated with patient satisfaction remain to be identified. Overall, there were no large changes in QoL 3 months after initiation of treatment, a finding that has been described previously.46,47
Our study must be interpreted within the context of its design. The IN-PATSAT32 module was designed to measure inpatient satisfaction with care, whereas some of the patients in our study received outpatient treatment (ie, systemic therapy). The EORTC QoL group recently introduced an extended module with a provisional list of 57 additional items to be added to the original module and applicable to any cancer care setting.1 However, because of the high treatment intensity in patients with pancreatic cancer, we believe that use of the current module was justified. All single-scale and multiscale domains seem applicable in pancreatic cancer.21 For example, waiting times for palliative systemic therapy are also applicable in the outpatient setting (ie, waiting times to get an outpatient appointment). Second, we had no information on postoperative complications or data on toxicity. This was caused by referral patterns in the Netherlands, where patients are often treated for adverse events (eg, toxicity) in a local hospital. In the future, patient-reported outcome data will be combined with clinical data obtained from audits and other registries.19 However, treatment outcomes (eg, complications) in terms of QoL were not related to patient satisfaction. Because of the design of the study, we had no information on patients who were eligible but not included in this study. Although we aimed to include all consecutive patients, not all patients participated, which may limit generalizability. Declining response rates over time are common in health-related QoL studies, particularly those involving patients with advanced disease. In the present study, the response rate after 3 months was 78%, which is remarkably high compared with other studies, given that many patients were treated with palliative intent.46 Selective attrition, however, in which only the fittest patients complete the follow-up questionnaires, cannot be ruled out. Finally, the relatively small number of patients introduces statistical uncertainty.
Conclusions
Satisfaction with care decreased after treatment of pancreatic and periampullary cancer in this prospective cohort, whereas QoL did not. Expectation management through shared decision-making and attention to psychosocial problems and healthcare professionals’ communication skills may improve patients’ satisfaction with care.
