Effect of depression-related somatic pain on treatment satisfaction and daily living functions

Experiences and coping strategies of somatic symptoms in patients with depressive disorder: A qualitative study

BACKGROUND

Depressive disorder is the most prevalent mental illness and is characterised by the presence of mental and somatic symptoms, with the latter affecting 65.0% to 98.2% of patients with their general function and quality of life.

PURPOSE

The purpose of this study aimed to explore the experiences and coping strategies of somatic symptoms in Chinese patients with depressive disorder, and to gain new insight into the illness and the health care provided to patients.

METHODS

Semi-structured, in-depth interviews were conducted with 15 patients diagnosed with depressive disorder according to international classification of diseases 10th revision. The interviews were transcribed verbatim and the thematic analysis was adapted to the data. MAXQDA10 software was used to organise, encode, classify, induce, and extract themes.

RESULTS

Four major themes were extracted from the interviews: (1) descriptions of symptoms; (2) perceptions of the symptoms; (3) symptom disturbance; and (4) coping strategies of symptoms. Within the first theme, patients identified the following sub-themes: complex experiences of somatic symptoms, which were mainly in the neuromuscular system, circulatory respiratory system, gastrointestinal system and some symptoms without obvious systemic classification; difficulty in locating symptoms accurately; and being not consistent with examination results. The second theme included patient's inadequate understanding of somatic symptoms; and denial of the link between physical discomfort and depression. Disturbance of somatic symptoms embraced three sub-themes: (1) Uncertainty about somatic symptoms; (2) Struggling with daily life; (3) Impact on social activities; (4) feeling a decrease in family support. Lastly, coping strategies taken by patients in the face of various symptoms mainly included relying on drug treatment, avoiding stressors, diverting attention, and compromise or acceptance.

CONCLUSIONS

Patients with depressive disorder experience a variety of somatic symptoms that have a negative impact on social function and reduce their quality of life. Patients did not have an adequate understanding of their physical discomfort and lacked effective coping strategies for these somatic symptoms. Professional staff should pay more attention to patients' somatic symptoms and focus on targeted symptom management to facilitate patient recovery.

Frequency of mental disorders among chronic pain patients with or without fibromyalgia in Japan

Aim

To explore the characteristics of psychiatric morbidity in chronic pain patients who present with or without fibromyalgia.

Methods

Patients are referred to our chronic pain clinic from primary medical institutions, as we are a secondary medical institution. Although some patients have chronic pain, they have no clear organic disorder such as rheumatoid arthritis to account for the pain. Among the 367 new patients seen during the period from March 2009 to August 2012, 347 patients underwent psychiatric evaluation in face‐to‐face interviews with mental health specialists before a physical examination.

Results

Of the 347 patients examined, at least one psychiatric diagnosis was made for 94.6%. The average number of DSM‐IV‐TR diagnoses was 1.46 in the 330 chronic pain patients who had at least one psychiatric diagnosis. The breakdown of the number of psychodiagnoses was one in 60.8%, two in 27.1%, three in 4.9%, and more than three in 2.3% chronic pain patients with or without fibromyalgia. In fibromyalgia patients, the highest relative frequencies were found for somatoform disorders (76%), followed by dysthymic disorder (17%) and major depressive disorder (15%). In patients without fibromyalgia, the highest relative frequencies were found for somatoform disorders (64%), followed by major depressive disorder (15%) and dysthymic disorder (14%). Psychiatric disorders were found in 96.9% of fibromyalgia patients, and in 93.5% of chronic pain patients without fibromyalgia in Japan (no significant difference using chi‐square test).

Conclusion

Results show that chronic pain patients with or without fibromyalgia are extremely likely to be diagnosed with a psychiatric disorder.

Association between pain severity, depression severity, and use of health care services in Japan: results of a nationwide survey

BACKGROUND

Depression is often associated with painful physical symptoms. Previous research has seldom assessed the relationship between the severity of physical symptoms and the severity of mental and emotional symptoms of depression or other health outcomes, and no such studies have been conducted previously among individuals with depression in Japan. The aim of this study was to assess the relationship between the severity of physical pain and depression and other outcomes among individuals in Japan diagnosed with depression.

METHODS

Data for individuals aged 18 and older in Japan who reported being diagnosed with depression and also reported physical pain were obtained from the Japan National Health and Wellness Survey. These respondents were characterized on sociodemographics and health characteristics, and the relationship between ratings of severity on pain in the last week and health outcomes were assessed using bivariate correlations and generalized linear models. Measures included the Patient Health Questionnaire for depression severity, Medical Outcomes Study 12-Item Short Form Survey Instrument for health-related quality of life, the Work Productivity and Activity Impairment for work and activity impairment, and 6-month report of health care use.

RESULTS

More severe physical pain in the past week was correlated with more severe depression, worse health-related quality of life, lower health utility, greater impairment at work, and more health care provider visits. These relationships remained significant after incorporating sociodemographics and health characteristics in the statistical models.

CONCLUSION

Individuals whose depression is accompanied by more severe physical pain have a higher burden of illness than those whose depression includes less severe pain, suggesting that even partially ameliorating painful physical symptoms may significantly benefit patients with depression. Clinicians should take the presence and severity of physical pain into account and consider treating both the physical and emotional symptoms of these patients.
