RESUMEN
AIM: To evaluate the prevalence of pain in cancer outpatients in Taiwan and to investigate the impact of pain on quality of life (QoL) and patient satisfaction. Results were compared to those of a similarly designed study conducted in 2008 to identify trends. METHODS: Adult patients with cancer treated as outpatients in hospitals throughout Taiwan were recruited. Pain intensity and the extent to which pain interfered with QoL were self-reported using a modified version of the Brief Pain Inventory. Patients also indicated their level of satisfaction with their physician, as well as with their pain control. RESULTS: A total of 2652 patients were enrolled from 16 sites. Of these, 1167 (44.0%) patients reported experiencing pain during the previous week. Prevalence and severity of pain were highest in patients with progressive disease. A higher pain severity score was significantly associated with greater interference in both physical and psychological functions. Overall, 86.0% of all participants expressed satisfaction with their physician and 84.8% were satisfied with their pain control; satisfaction rates were associated with pain severity. Compared with the findings from the 2008 study, pain prevalence was notably lower and patient satisfaction was significantly greater in the current study. CONCLUSIONS: Prevalence and severity of pain were associated with disease stage. Pain interference on QoL correlated significantly with pain severity. Treatment of pain in cancer patients in Taiwan seems to have improved from 2008 to 2014, possibly attributable to new cancer pain treatment guidelines and the wider availability of novel analgesic therapies.

PURPOSE: Poor adherence to analgesic drugs is one of the most common barriers to adequate pain management. This prospective, cross-sectional, patient-oriented observational study aimed to explore the adherence rate, clinical factors, and impact of adherence to analgesic drugs on the quality of life (QoL) among cancer outpatients in Taiwan. METHODS: Eight hundred ninety-seven consecutive adult outpatients with cancer who had reported tumor pain and received regular analgesic drug treatment were enrolled from 16 medical centers across Taiwan. The Brief Pain Inventory was used to assess pain intensity and QoL. Morisky's four-item medication adherence scale was used to assess adherence to analgesic drugs. Clinical factors possibly associated with good adherence to analgesic drugs were analyzed using multivariate logistic regression analyses. RESULTS: Of the 897 patients, 26.9% met criteria for the good, 35.5% for the moderate, and 37.6% for the poor adherence groups. The good adherence group had significantly better QoL outcomes than the moderate and poor adherence groups (all p < 0.05). Age ≥ 50 years, head and neck or hematological malignancies, cancer-related pain, patients who agreed or strongly agreed that the side effects of analgesic drugs were tolerable, and patients who disagreed or strongly disagreed that the dosing schedule could be flexibly self-adjusted to deal with the actual pain were predictors of good adherence to analgesic drugs. CONCLUSIONS: Awareness of the clinical factors associated with adherence to analgesic drugs may help clinicians to identify cancer patients at a greater risk of non-adherence, reinforce optimal pain management, and improve the QoL by enhancing adherence to pain medications.

PURPOSE: The purpose of this study is to investigate the prevalence of pain, pain management, and impact of recent pain on daily functioning in patients with head and neck cancer (HNC) and patients with other cancers. METHODS: This multi-center survey was conducted by using Brief Pain Inventory questionnaire to evaluate pain status and its impact on daily functioning. RESULTS: A total of 3289 patients were analyzed including 708 HNC patients and 2581 patients with other cancers. The overall pain prevalence was 69.17%. A higher percentage of HNC patients had recent pain (60.59 vs. 44.01%, P < 0.001), required pain management (86.29 vs. 72.03%, P < 0.001), and used any analgesics (53.81 vs. 34.52%, P < 0.001). HNC patients with pain management had a higher prevalence of recent pain (85.83 vs. 81.14%, P = 0.044) and a slightly lower satisfaction rate (74.00 vs. 79.70%, P = 0.070). Regarding the impact of pain on daily functioning, HNC patients had a lower mean interference score for general activity such as walking, normal work, sleep, and life enjoyment. CONCLUSIONS: The HNC patients may need more intensive pain management to achieve optimal pain control and maintain daily functioning.

BACKGROUND: Knowledge on periprosthetic infection and mortality rate following total knee arthroplasty (TKA) is essential for justifying this treatment in patients with cancer; however, relevant data from population-based studies are lacking. Therefore, we examined 1-year periprosthetic infection, mortality, and 5-year relative survival rates in cancer patients who underwent TKA. METHODS: This is a population-based cohort study based on analysis of the Taiwan National Health Insurance Research Database. We enrolled a total of 2294 cancer patients and 131,849 patients without cancer (control group) who underwent TKA between January 1, 1997, and December 31, 2011. All patients were followed until death, infection, withdrawal from the National Health Insurance, or December 31, 2012. RESULTS: The periprosthetic knee joint infection rate in cancer patients (1.73%) was not significantly higher than that in the control group (1.87%). However, the 1-year mortality rate was significantly higher (p < 0.05) in the cancer group (4.10%) than in the control group (1.66%). The overall 5-year survival rate was 93.10% as compared with those without cancers. CONCLUSION: Low periprosthetic knee joint infection rates and high 5-year relative survival rates indicate the feasibility of TKA in cancer patients. However, the surgeon should take into account a higher mortality rate in the first year following TKA.

CONTEXT: Undertreatment of cancer pain among outpatient cancer patients needs to be addressed to enhance care and improve patients' quality of life (QoL). OBJECTIVES: This prospective, cross-sectional, patient-focused study aimed to explore the prevalence of pain and undertreatment of cancer pain in outpatients in Taiwan. METHODS: A total of 2652 non-selected outpatients with cancer and aged 20 years or older from 16 medical centers across Taiwan were included in this survey. All patients completed a questionnaire based on the Brief Pain Inventory. Pain management index (PMI) was used to evaluate the adequacy of pain management. Possible clinical variables of patients with positive PMI were examined by univariate and multivariate logistic regressions. RESULTS: A total of 1659 (62.6%) outpatients had experienced some degree of pain; among these, 32.4% had negative PMI. Patients with a negative PMI score had significantly poor outcomes of QoL and a significantly higher tendency toward dissatisfaction with pain control by the physician and with the prescribed analgesic drugs. Female gender, primary tumor from breast, non-cancer-related cause of pain, and hospital locations from north Taiwan were independent variables that predicated patients with undertreatment of cancer pain. Most importantly, a forward trend of undertreatment of pain among patients who presented with lower prevalent rate of pain was observed. CONCLUSION: One-third of Taiwanese outpatients experienced pain because of undertreatment. Awareness of the prevalence of undertreatment of cancer pain and identification of the vulnerable subjects may assist in enhancing patient care and improving patient's QoL.
