Adequacy of Pain Control in Patients With Advanced Cancer in Pakistan

Perceptions and experiences of laws and regulations governing access to opioids in South, Southeast, East and Central Asia: A systematic review, critical interpretative synthesis and development of a conceptual framework

BACKGROUND

Opioids are essential medicines. Despite international and national laws permitting availability, opioid access remains inadequate, particularly in South, Southeast, East and Central Asia.

AIM

To review evidence of perceptions and experiences of regulatory enablers and barriers to opioid access in South, Southeast, East and Central Asia.

DESIGN

Systematic review of post-2000 research according to PRISMA guidelines. Data were subjected to critical interpretive synthesis. International, national and sub-national barriers were organised developing a conceptual framework of opioid availability.

DATA SOURCES

PsycINFO, Medline, Embase, The Cochrane Library. CINAHL, Complete and ASSIA from 2000 until 20th May 2019.

RESULTS

21/14097 studies included: quantitative n = 15, qualitative n = 3 and mixed-methods n = 3. Four barrier/enabler themes were developed: Legal, regulatory, socio-political; lack of laws explicitly enabling opioid access, restrictive international controls and clinician prescribing concerns. Opioid availability; limited availability, poor policymaker and clinician education regarding opioid benefits, poor continuity of supply. Opioid Accessibility; medicine costs, distance to prescribing centres. Prescribing; extensive bureaucratic barriers, lack of human resources for prescribing. We present a novel framework of a self-perpetuating model of inadequate opioid provision. The Single Convention on Narcotics provides the context of restrictive laws and negative attitudes amongst policymakers. A consequent lack of prescribers and clinicians' negative attitudes at sub-national levels, results in inadequate access to and use of opioids. Data of inadequate consumption informs annual requirement estimates used by the International Narcotics Control Board to determine future opioid availability.

CONCLUSIONS

Regulatory and socio-political actions unintentionally limit opioid access. International and national laws explicitly enabling opioid access are required, to assuage concerns, promote training and appropriate prescribing.

Attitudes and appropriateness of pain management in cancer patients using pain management index

Objectives

Inadequate management of cancer pain (CP) remains a global medical problem. In this study, the aim was to assess attitudes of cancer patients towards their CP treatment and to evaluate effectiveness of pain management.

Methods

A sample of 300 adult cancer patients admitted to a single hospital were face-to-face interviewed in a cross-sectional study design using a structured questionnaire. The short form of the Brief Pain Inventory was used to collect data on pain, and Pain Management Index (PMI) was calculated to assess adequacy of pain management.

Key findings

Median age of patients was 53 years (interquartile range, 43–63). Half of patients (50.5%) believed their pain therapy needs improvement. Almost half patients had severe pain at interview (49.8%). Pain interfered most with patient enjoyment of life with a mean interference score 6.13 ± 2.37. Majority of cancer patients (84.3%) received a non-opioid analgesic while a minority (15.7%) received opioid analgesic in which morphine was the most common drug. The use of non-opioid adjuvants was minimal. Mean PMI for patients was −1.15 ± 0.75 (range −2 to +1), and most patients (80.3%) had inadequate pain treatment. Gender and smoking status of patients were significantly associated with adequacy of pain management (P = 0.009 and P = 0.004, respectively). There were no associations between patient age, educational level or tumour characteristics and adequacy of pain management.

Conclusions

Cancer patients in this study present with severe pain and the rates of undertreatment are high. There is an urgent need to improve management plans to assure appropriate use of therapeutic modalities for treatment of cancer-related pain.

Pain Severity and Adequacy of Pain Management in Terminally Ill Patients with Cancer: An Experience from North Palestine

Aim:

Chronic pain is common in terminally ill patients with cancer and affects their quality of life. In this study, we wanted to evaluate pain severity and the adequacy of prescribed analgesics in terminally ill patients with cancer in North Palestine.

Methods:

We conducted a cross-sectional descriptive study in North Palestine on 77 terminally ill patients with cancer. Pain experience was evaluated with Brief Pain Inventory-Short Form (BPI-SF). Pain management index (PMI) was calculated to determine the adequacy of interventions. The relationships between adequacy of pain management and socioeconomic and clinical factors were analyzed by the covariance method. Statistical analyses were performed using Statistical Package for the Social Sciences (SPSS version 15.0 [SPSS Inc., Chicago, USA]).

Results:

Fifty-nine patients (76.6%) reported moderate-to-severe pain. According to the PMI, only 64.9% of the patients received adequate pain management. Thirty-five patients (45%) wanted additional treatment or an increase in the dose of pain medications. Although men and women reported similar pain severities, women were more likely to be inadequately treated (P = 0.027). Pain severity was significantly less in patients who received health-care services at least once in the last month before the interview, compared to those without recent access to health care (P = 0.024).

Conclusion:

There is substantial inadequacy in pain management in patients with cancer. The BPI-SF should be routinely used to evaluate pain severity, and analgesics should be prescribed equitably without discrimination with regard to gender and socioeconomic status of patients.

Home Hospice, Not Hospital

In December 2017, my mother was diagnosed with an end-stage pancreatic cancer. In the following weeks, she had to be taken to the emergency room frequently due to worsening infections, electrolyte imbalance, and vertigo, which often led to delirium. The doctors treating her were well qualified but lacked education and training about palliative and end-of-life care issues, which was reflected in their clinical practice. They kept treating her medical conditions as if she could be cured; no one recommended comfort measures only. After much deliberation and with some degree of hesitation, I raised the idea of palliative care with the rest of my family. Asking for palliative care-that is, accepting that the medical treatments were not working-sounded like the antithesis of my clinical work as a doctor and my duty as a son. To my surprise, my family agreed; we refused yet another hospital admission and brought her home. She has been spending the last few months in the comfort of her home being cared for by her loving family.
