A comprehensive, patient-centered approach is required to accomplish cancer best standards of care.1 This approach reflects the holistic conceptualization of health in which the physical, emotional, and social dimensions of the human being are considered when providing medical care. As a result, to look after all patient needs, interdisciplinary and well-coordinated interventions are recommended. Cancer patients should be provided not only with diagnostic, treatment, and follow-up clinical service, but also with the supportive assistance that may positively influence all aspects of their health.

To appraise physical, social, emotional and spiritual issues and to develop supportive interventional action plans, the National Comprehensive Cancer Network (NCCN) recommends screening all cancer patients for distress.2 In particular, screening the emotional component of distress occupies a prominent place in this process because it is now recognized as the sixth vital sign in oncology.3 Even though the influence of emotional distress over cancer mortality rates and disease progression is still under scrutiny,4 its plausible implications over treatment compliance have been pointed out. Patients with higher levels of emotional distress show lower adherence to treatment and poorer health outcomes.5 Furthermore, prevalence rates of emotional distress in cancer patients from ambulatory settings6 and oncology surgical units have been studied and have provided justification for distress management.7 Studies have shown low ability among oncologists to identify patients in distress and oncologists’ tendency to judge distress higher than the patients themselves.8 As a consequence, to achieve systematic distress evaluations and appropriate referrals for care, guidelines for distress management should be implemented in clinical settings. It is recommended that tests are conducted to find brief screening instruments and procedures to assure accurate interventions according to patient specific needs.

This article presents the process of implementing a distress management program at HIMA-San Pablo Oncologic Hospital in Caguas, Puerto Rico, with particular emphasis on the management of emotional distress, which has been defined as the feeling of suffering that cancer patients may experience after diagnosis. In addition, we have included data from a pilot study that was completed for content validation of the Patient Health Questionnaire (PHQ-9) to estimate depression levels in Puerto Rican cancer patients.

Methods

HIMA-San Pablo operates a group of privately owned hospitals in Puerto Rico. It established a cancer center in Caguas in 2007, recruiting a multispecialty medical faculty to provide cancer care and bone marrow transplants for adult and pediatric patients. The cancer center, currently named HIMA-San Pablo Oncologic Hospital (HSPOH), is a hospital within a hospital licensed by the Puerto Rico Department of Health. In 2007, a cancer committee was established as the steering committee to ensure the delivery of cancer care according to best standards of care. The committee took responsibility for developing all activities needed to achieve the American College of Surgeons’ Commission on Cancer (CoC) accreditation under the category of Comprehensive Community Cancer Center. The committee established a psychosocial team to develop a protocol for the delivery of distress management for adult patients. (The psychosocial needs of pediatric patients are assessed through other procedures.)

To develop the protocol, principles of input-output model of research and quality analysis in health care were applied.9 The input-output model, with its origin in engineering, helped map systematic activities to transform empirical data on cancer psychosocial care into operational procedures. Focus was given to data gathering (input), information organization and analysis (throughput), and the schematization of emotional distress management care (output).

The input phase

In the input phase, elements of psychosocial care and operational definitions related to distress management in general were identified through literature review (Table 1). Basic parameters for distress management were clarified, resulting in a conceptual framework based in four remarks: First, according to NCCN, distress is a multifactorial unpleasant emotional experience of a psychological, social, and spiritual nature. It may interfere with the ability to cope effectively with cancer, its symptoms and its treatment. Its intensity may fluctuate from feelings of suffering and fear to incapacitating manifestations of anxiety and depression2 and its severity may hamper patient quality of life and treatment compliance.

Second, distress management requires the intervention of an interdisciplinary team with both medical and allied health professionals. This may include mental health specialists and other professionals with training and experience in cancer-related issues, who work with reciprocal channels of communication for the exchange of patient information.

Third, NCCN recommends using the Distress Thermometer for patient initial distress screening.10-12 It consists of a numeric scale ranging from 0 (no distress) to 10 (severe distress) in which patients classify their level of distress. The numeric scale is followed by a section in which patients identify areas of practical, familiar, emotional, spiritual/ religious, and physical concerns. Based on responses, interviews may follow to set distress management interventions.

Fourth, screening and assessment are different but sequential and complementary stages of distress management. Screening is viewed as a rapid strategy to identify cancer patients in distress. Assessment looks out for a broader appraisal and documentation of factors with repercussions over patient distress level and resiliency capability.13 In many instances, the patient’s emotional distress is better understood in the assessment phase.

The throughput phase

Within the throughput phase of information organization and analysis, an inventory of health professionals and other in-house consultants needed for distress management was completed. Roles and procedures for information sharing were determined, and we established collaborative agreements with professionals in the community who could contribute to distress management. Members of the psychosocial team held workshops to discuss elements of NCCN guidelines for distress management and to create an action plan for the implementation of the protocol. Data analyses were performed to create a demographic profile of the oncology population at the hospital and assess patient willingness to receive emotional support services,16 which led to the implementation of support group meetings at which additional substantive information was collected about issues affecting cancer patients’ emotions.

The NCCN Distress Thermometer for measuring distress was translated to Spanish. Its format was adapted, and it was identified as a distress screening tool (DST), which we named Distress Assessment Tool for Oncology Patients (Figure 1). The instrument helps for rapid screening of patient needs and proper determination of initial interventions. In addition, psychometric properties of several instruments were reviewed for instances when patient emotional distress could not be clearly determined. We decided to proceed with the validation of the 9-item Patient Health Questionnaire (PHQ-9) to estimate patient depression level. A proposal for content validation of the PHQ-9 was approved by the University of Puerto Rico institutional review board, and patients were recruited to participate in the pilot study.

The PHQ-9. The PHQ-9 is a self-report version of the PRIME-MD instrument developed to assess mental disorders in clinical settings. It is based on DSM-IV diagnostic criteria.17 The PHQ-9 is the depression module with nine depression symptoms to check off if they become the cause of emotional impairment. Respondents categorized depression symptoms in four frequency degrees representing numeric values: 0 (not at all), 1 (several days), 2 (more than half the days), 3 (nearly every day). Measures of depression severity are subsequently determined in a Likert-type scale according to numeric calculations of responses: 0-4 (none severe depression), 5-9 (mild), 10-14 (moderate), 15-19 (moderately severe), and 20-27 (severe-major depression).

The instrument is widely used because of its validity in small and large populations. It showed adequate reliability and validity in a small sample of head and neck cancer patients, with a Cronbach’s alpha of 0.80 and a correlation coefficient of 0.71.18 Similarly, it showed good performance in identifying major depression in 4264 cancer outpatients, with sensitivity of 93%, specificity of 81%, and a positive predictive value (PPV) of 25% and negative predictive value (NPV) of 99%.19 Even when administered on a touch screen computer, the instrument showed valid data of depression from patients in treatment.20

The Beck Depression Inventory. We used the Beck Depression Inventory (BDI-II) Spanish version as the gold standard measure for the validation study. It is a 22-items inventory that measures attitudes and symptoms of depression.21 It can be administered in 10 minutes and has shown good psychometric measures when administered in Spain and Puerto Rico.22, 23

The pilot study. In all, 44 cancer patients who were receiving outpatient treatment at the radiotherapy unit agreed to participate in the study. The participants signed a consent form after the confidentiality protection measures and the main objectives of the study had been explained to them. Patients were interviewed individually during November and December 2012, with the Spanish versions of the PHQ-9 and BDI-II administered by one of two interviewers. At the beginning of each interview, the patient was asked 10 questions so that we could gather demographic data and confirm participant eligibility: aged 21 years or older, born and raised in Puerto Rico, being a Spanish speaker, and having a primary cancer diagnosis with no previous disease. Three patients were excluded from the sample because they either had cancer previously or had a recurrence or metastasis. The final sample consisted of 41 outpatients (N = 41).

Data analysis for demographics was completed with STATA v.12 software. Measures of central tendency and dispersion as well as PHQ-9 internal consistency analysis were made through Cronbach alpha with SPSS.

From a total of 41 patients surveyed, 22 (54%) were men and 19 (46%) were women, with an overall median age of 61 years. Among the men, 15 (68%) had a prostate cancer diagnosis and among women, 9 (47.4%) had a breast cancer diagnosis. In regard to health insurance, 19 (46%) had Medicare or Veterans/federal insurance coverage, and 13 (32%) had Reforma, the Puerto Rican government health insurance program partially funded by Medicaid funds. In addition, 8 participants (20%) were unemployed or disabled. As previously stated, all of the patients were in ambulatory care. Only 3 (7%) were participating in support groups.

Of all the respondents, 16 (39%) reported some level of depression. In particular, 2 (5%) showed severe-major depression, 4 (10%) moderately severe depression, and 10 (24%) moderate depression. Of those with depression, 8 (50%) were women, 8 (50%) were men. All 6 of the patients with head and neck cancer showed moderate or moderately severe depression (Table 2).

Table 2 Patient characteristics
In terms of psychometric measures, the PHQ-9 showed good internal consistency with a Cronbach alpha of .83. In addition, it showed a high reliability coefficient of 95.5% indicating a high level of correlation between scores on both the PHQ-9 and BDI-II gold standard measure of each participant. Patients showing moderately severe depression in the PHQ-9 for example, had the same result in the BDI-II.

When respondent PHQ-9 scoring reflected moderate to severe depression (>10), a letter was sent to the patient’s radio-oncologist for referral to counseling and clinical psychological evaluation. All participants had access to the support group program, to a radiotherapy education program meeting weekly, and written information about their cancer diagnosis and treatment. They also were interviewed by the psychosocial coordinator or patient navigator for further assessment.

The output phase

In the output phase, a graphic representing the process of emotional assessment at the institution was created and then modified. PHQ-9 was added to the process when it was found suitable to assess level of depression contributing to the identification of patients requiring psychological and psychiatric assistance which by other means would be missed. PHQ-9 was useful in the busy clinical setting as it was completed, scored and interpreted in minutes. It showed the potential for routine evaluations when looking to identify improvement or deterioration in depression levels thus helping to monitor responses to treatment and providing insights for follow up interventions. As stated by NCCN guidelines, distress should be monitored, documented and managed at all stages of the cancer continuum.

Results and discussion

The protocol for distress management at HSPOH is based on the 2013 NCCN guidelines. Cancer patients are screened for levels of distress in all settings (inpatients and outpatients). Screening is held with the DST Spanish translation at the moment of diagnosis or as soon as possible after a diagnosis is made. Screening for distress is also done before or after surgery, in recurrence or progression, and when clinically indicated. Patients are informed that distress management is an essential part of their care and are encouraged to provide information so that we can make a proper need assessment.

Patients are screened by the psychosocial coordinator or patient navigator who administers the DST followed by in-depth interviews for additional appraisal. An action plan is designed based on patient needs, which include their intervention and the intervention of other members of the psychosocial team from the institution and/or from the community. Additional in-house health professionals contributing in distress management include, but are not limited to: physicians; clinical psychologists; health educators; social workers; dietitians; chaplains; and physical, respiratory, speech, and/or swallow therapists. Follow-up and rescreening sessions are scheduled to assure coordination of services between those health professionals as well as to secure continuity of distress management during all stages of the cancer continuum.

The results of the DST are filed in patient medical records. Members of the psychosocial team also document their interventions in the patient medical record, which helps in the exchange of information among the cancer care team. The psychosocial team meets once a month – or as required for extraordinary cases – to review and discuss the cases, determine the best options for distress management, and identify areas for psychosocial care improvement. Those findings and the results of distress management in patient level of satisfaction are then reported and discussed quarterly by the psychosocial coordinator and the cancer committee.

Figure 2 shows in what phase of emotional distress assessment the PHQ-9 was included. Patients reporting four or more of the six areas of concern related to emotional distress in the DST (Figure 1) are automatically referred to a mental health specialist. But when patients report three areas of concern with no clear data on their specific level of depression, PHQ-9 is administered to differentiate those who need a mental health specialist from those who could be adequately supported by health education and support group interventions. In this way detrimental outcomes such as duplicity and over or underuse of services and resources are reduced. In addition, it is recognized that using an interview after the administration of the DST to determine distress management actions does not always provide enough information about a patient’s emotional circumstances and previous comorbidities. Patient responses during interviews may be influenced by the patient’s level of literacy, verbal comprehension, and communication style,24 so emotional distress can go unrecognized during interviews, resulting in delays for treatment and supportive care.

High-quality standards of care lead to the simultaneous management of factors affecting patient health in a coordinated continuum of care. They emphasize the development of protocols for supportive care services, focusing on the diversity of patient needs aside from the clinical treatment of a disease. Traditionally, disease management was based in a biomedical framework with emphasis in the biological component of illnesses and the prevention of disease transmission. Treating physical symptoms after diagnosis to prevent mortality was the standard of care, thus reflecting the predominant epidemiological approach ruling medical practice when infectious diseases were leading cause of death. Such an approach had strong limitations in that it did not consider emotional, social, and spiritual variables and their implications for patient health. As chronic diseases such as cancer expanded the scope of human maladies, frameworks for disease management changed and new approaches emerged.25 New socio-ecological models were applied, based on the assumption that health is maintained to a greater extent as a result of how effective the multidimensional factors of patient health are undertaken.

National guidelines in oncology consider such socio-ecological models emphasizing the delivery of patient-centered, interdisciplinary, and evidence-based care. That does not mean that institutions should apply protocols of psychosocial care as previously developed, but that they should test, review, adapt, and improve them during the implementation of the care. In fact, NCCN encourages conducting trials to examine protocols, screening instruments, and models of intervention to determine applicability to particular settings.2

Findings from a study by NCCN member institutions to evaluate progress of implementing distress management guidelines found that 53% (n = 8) of respondent institutions conducted routine distress screening. Of those, 37.5% (3) relied only on interviews. That finding is of concern because if interviews are not standardized and have not been systematically evaluated, then their sensitivity and specificity in identifying distressed patients is unknown.26 Accordingly, the process described in this article and the PHQ-9 validation was an effort to standardize emotional distress management, and was underlined as an achievement during the CoC accreditation visit to the cancer center in December 2013. The hospital was accredited as a comprehensive community cancer center with gold commendations, becoming the first privately owned hospital in Puerto Rico to achieve the accreditation.
