Pain characteristics and analgesic intake before and following cardiac surgery

Background: Cardiac surgery is a common intervention that involves several pain-sensitive structures, and intense postoperative pain is a predictor of persistent pain. Aims: To describe pain characteristics (i.e. intensity, location, interference, relief) and analgesic intake preoperatively and across postoperative days 1 to 4 after cardiac surgery, and to explore associations between postoperative pain and demographic and clinical characteristics. Methods: Four hundred and sixteen patients (24% women) undergoing elective coronary artery bypass grafting and/or valve surgery were enrolled in a randomized controlled trial. Data were collected using standardized measures including the Brief Pain Inventory-short form. A linear mixed model analysis estimated the impact of sex, age, body mass index, analgesic intake and preoperative pain on postoperative worst pain ratings in the previous 24 hours from postoperative days 1 to 4 prior to discharge Results: Thirty-eight per cent of the cardiac surgery patients reported preoperative pain. Postoperative worst pain remained in the moderate to severe range for the majority of patients across day 1 (85%) to day 4 (57%), mainly around the chest incision area for the majority (70%). Mean oral morphine intake was 17 mg/24 h (day 1: 27mg; day 4: 10mg). Lower age, female sex, preoperative pain and analgesic intake had a statistically significant association with higher postoperative worst pain ratings. Conclusion: Study findings demonstrated a high prevalence of moderate to severe pain after cardiac surgery and insufficient analgesic administration. Results indicated that patients were discharged from hospital with unrelieved pain and a potential risk for further postoperative complications.

The impact of an educational pain management booklet intervention on postoperative pain control after cardiac surgery.

Background: Relevant discharge information about the use of analgesic medication and other strategies may help patients to manage their pain more effectively and prevent postoperative persistent pain. Aims: To examine patients’ pain characteristics, analgesic intake and the impact of an educational pain management booklet intervention on postoperative pain control after cardiac surgery. Concerns about pain and pain medication prior to surgery will also be described. Methods: From March 2012 to September 2013, 416 participants (23% women) were consecutively enrolled in a randomized controlled trial. The intervention group received usual care plus an educational booklet at discharge with supportive telephone follow-up on postoperative day 10, and the control group received only usual care. The primary outcome was worst pain intensity (The Brief Pain Inventory – Short Form). Data about pain characteristics and analgesic use were collected at 2 weeks and at 1, 3, 6 and 12 months post-surgery. General linear mixed models were used to determine between-group differences over time. Results: Twenty-nine percent of participants reported surgically related pain at rest and 9% reported moderate to severe pain at 12 months post-surgery. Many participants had concerns about pain and pain medication, and analgesic intake was insufficient post-discharge. No statistically significant differences between the groups were observed in terms of the outcome measures following surgery. Conclusion: Postoperative pain and inadequate analgesic use were problems for many participants regardless of group allocation, and the current intervention did not reduce worst pain intensity compared with control. Further examination of supportive follow-up monitoring and/or self-management strategies post-discharge is required.

Self-management of cardiac pain in women: an evidence map

Objective To describe the current evidence related to the self-management of cardiac pain in women using the process and methodology of evidence mapping. Design and setting Literature search for studies that describe the self-management of cardiac pain in women greater than 18 years of age, managed in community, primary care or outpatient settings, published in English or a Scandinavian language between 1 January 1990 and 24 June 2016 using AMED, CINAHL, ERIC, EMBASE, MEDLINE, Proquest, PsychInfo, the Cochrane Library, Scopus, Swemed+, Web of Science, the Clinical Trials Registry, International Register of Controlled Trials, MetaRegister of Controlled Trials, theses and dissertations, published conference abstracts and relevant websites using GreyNet International, ISI proceedings, BIOSIS and Conference papers index. Two independent reviewers screened using predefined eligibility criteria. Included articles were classified according to study design, pain category, publication year, sample size, per cent women and mean age. Interventions Self-management interventions for cardiac pain or non-intervention studies that described views and perspectives of women who self-managed cardiac pain. Primary and secondary outcomes measures Outcomes included those related to knowledge, self-efficacy, function and health-related quality of life. Results The literature search identified 5940 unique articles, of which 220 were included in the evidence map. Only 22% (n=49) were intervention studies. Sixty-nine per cent (n=151) of the studies described cardiac pain related to obstructive coronary artery disease (CAD), 2% (n=5) non-obstructive CAD and 15% (n=34) postpercutaneous coronary intervention/cardiac surgery. Most were published after 2000, the median sample size was 90 with 25%–100% women and the mean age was 63 years. Conclusions Our evidence map suggests that while much is known about the differing presentations of obstructive cardiac pain in middle-aged women, little research focused on young and old women, non-obstructive cardiac pain or self-management interventions to assist women to manage cardiac pain.

Self-Management of Cardiac Pain in Women: A Meta-Summary of the Qualitative Literature:

Symptom recognition and self-management is instrumental in reducing the number of deaths related to coronary artery disease (CAD) in women. The purpose of this study was to synthesize qualitative research evidence on the self-management of cardiac pain and associated symptoms in women. Seven databases were systematically searched, and the concepts of the Individual and Family Self-Management Theory were used as the framework for data extraction and analysis. Search strategies yielded 22,402 citations, from which 35 qualitative studies were included in a final meta-summary, comprising data from 769 participants, including 437 (57%) women. The available literature focused cardiac pain self-management from a binary sex and gender perspective. Ethnicity was indicated in 19 (54%) studies. Results support individualized intervention strategies that promote goal setting and action planning, management of physical and emotional responses, and social facilitation provided through social support.

Association between self-perceived pain sensitivity and pain intensity after cardiac surgery

Background and purpose Cardiac surgical pain remains a clinical challenge affecting about 40% of individuals in the first six months post-cardiac surgery, and continues up to two years after surgery for about 15–20%. Self-perceived sensitivity to pain may help to identify individuals at risk for persistent cardiac surgical pain to optimize health care responses. The purpose of this study was to assess the relationship between self-perceived pain sensitivity assessed by the Pain Sensitivity Questionnaire (PSQ) and postoperative worst pain intensity up to 12 months after cardiac surgery. Sex differences in baseline characteristics and the PSQ scores were also assessed. Methods This study was performed among 416 individuals (23% women) scheduled for elective coronary artery bypass graft and/or valve surgery between March 2012 and September 2013. A secondary data-analysis was utilized to explore the relationship between preoperative PSQ scores and worst pain intensity rated preoperatively, across postoperative Days 1–4, at 2 weeks, and at 1, 3, 6, and 12 months post-surgery. Linear mixed model analyses were performed to estimate changes in pain intensity during 1-year follow-up. Results The mean (±standard deviation) PSQ-total score was 3.3±1.4, with similar scores in men and women. The PSQ-total score was significantly associated with higher worst pain intensity ratings adjusted for participant characteristics (p=0.001). Conclusion Use of the PSQ before surgery may predict cardiac surgical pain intensity. However, previous evidence is limited and not consistent, and more research is needed to substantiate our results.

A review of self‐rated generic quality of life instruments used among older patients receiving home care nursing

In the last two decades, quality of life and health-related quality of life have become commonly used outcome measures in the large number of studies evaluating healthcare and home care nursing. The objective of this systematic search and review was to evaluate studies that include self-rated generic quality of life instrument used among elderly patients receiving home care nursing. Searches were conducted in Medline, Embase, PsycINFO and Cinahl for articles published between January 2005 and June 2016, with 17 studies in eight countries meeting the inclusion criteria and assessed for quality. Overall, the review shows great variations in the included studies regarding characteristics of the participants and place of origin, the generic quality of life instruments applied and their dimensions. In this review, we raise the question of whether the generic questionnaires used to measure quality of life do in fact measure what is essential for quality of life in elderly users of home care nursing. The psychological and physical dimensions of quality of life were assessed in almost all included studies, while older-specific dimensions like autonomy, control and sensation were less frequently assessed. There is reason to believe that generic quality of life instruments frequently do not capture the dimensions that are most important for elderly people with health problems in need of home care nursing.
