A literature review exploring how healthcare professionals contribute to the assessment and control of postoperative pain in older people

Little research has examined the care older people receive in the acute surgical setting. Although pain assessment and management are judged to be a priority in nursing, often pain, in older people, is undermanaged for a variety of reasons. Factors such as stoicism, communication and ageism can shape both the patients’ and nurses’ attitude towards the perception of pain which subsequently affects pain management. Through a review of the literature, this paper aims to: (i) identify how healthcare professionals contribute to the assessment and control of postoperative pain in older people and (ii) explore potential barriers to achieving more advantageous pain control in this group. It is suggested that to improve pain management there is a need to individualize pain assessment for older people and to assist clinicians with enhancing their education and decision‐making abilities in this field. This may best be achieved by supporting a programme of change to develop the skills of staff and encouraging learning through reflective practice. There is however a need for further research in this area.     

A comprehensive strategy for the evaluation and triage of the chest pain patient: A cost comparison study

BACKGROUND: Our objective was to determine the cost-effectiveness of a comprehensive, risk-based triage system, composed of multiple critical pathways, with the use of early myocardial perfusion imaging (MPI) in low-risk patients. We found previously that a chest pain evaluation system that uses MPI in low-risk patients was safe and effective, but the cost-effectiveness of this approach was not studied. METHODS AND RESULTS: We compared two groups. The Acute Cardiac Team (ACT) group (n = 874) was assigned prospectively to 1 of 4 risk levels by emergency department (ED) physicians. Level 1, 2, and 3 patients were admitted; level 4 patients were evaluated in the ED. Level 3 and 4 patients underwent ED MPI. The control group (n = 713) represented consecutive patients evaluated in the prior year according to standard care and assigned retrospectively to an ACT level based on the presenting electrocardiographic and clinical data. Record and hospital administrative data were assessed for clinical variables, outcomes, lengths of stay, and all expenses incurred within 30 days of the index visit. The baseline characteristics of the two groups were similar, including age, sex, myocardial infarction prevalence, and 30-day revascularization rates within each level or between the two groups. Mean costs per encounter were reduced for the ACT patients for each level, which was significant when all patients were compared ($5,030 +/- $7,081 vs $6,044 +/- $10,432, P =.02). Use of MPI in the low-risk patients was associated with reduced costs (level 3, $4,958 +/- $4,948 vs $5,051 +/- $7,036; level 4, $1,529 +/- $2,664 vs $1,794 +/- $6,854) and was associated with a significantly lower angiography rate and shorter length of stay. CONCLUSIONS: Implementation of a comprehensive strategy for chest pain evaluation and triage reduced overall costs for patients with chest pain on presentation. Acute MPI in the ED setting did not increase net cost.

Back pain from the epidemiological point of view

Summary In the last decades back pain has reached dramatic proportions in industrialized countries. Disorders of the back are nowadays the leading cause of direct and indirect health care costs. Accurate prevalence estimates are needed to serve as a basis for health care evaluations. A review of epidemiologic studies in the general population reveals that back pain has reached a prevalence of 40 % for current pain. 7 to 18 % are “frequently”, “often”, “daily” or “constantly” affected. 75 % of the adult population suffers from back pain during the last year. 80 to 90 % of the adult population in industrialized countries experience back pain ever. Gender specific differences are only present in severe, chronic forms which are more often experienced by women. Back pain has a prevalence maximum at 50 to 64 years. Older persons display lower prevalence estimates. The prevalence maximum in men is one decade earlier than in women. There are several potential explanations for this prevalence pattern that are discussed in the article. Back pain can be classified by location, temporal characteristics, pain intensity and pain history. Currently, for none of these dimensions generally accepted, uniformly employed and validated definitions are available. In most of the industrialized countries back pain is one of the most expensive symptoms. 75–90 % of the direct and indirect health care costs were caused by those 5–10 % of patients who are disabled. As predictors of back pain a history of back pain and job satisfaction play by far a more important role than the extensively studied mechanical factors. For a first episode of back pain the prognosis is favorable. If the pain persist for more than three months the prognosis is unfavorable. After six months of absenteeism because of back pain more than half of the afflicted never return to work. Rarely back pain is present as a single symptom. In more than 80 % back pain is associated with pain in at least one joint. It remains to be studied if back pain may be viewed as an entity or as part of a more complex pain syndrome.      

The effect of fibrin sealant haemostasis on post-operative pain in tonsillectomy

Pain following tonsillectomy is an important problem. It is caused by the surgical trauma of excision and haemostasis. Numerous surgical and pharmacological solutions have been tried, with disappointing results. Fibrin sealant is a widely used atraumatic haemostatic agent. This study aims to determine whether tonsillectomy with fibrin sealant haemostasis results in less post-operative pain than that with the conventional technique of diathermy. Fifty consecutive adult patients undergoing tonsillectomy were prospectively studied. They were randomized to receive either fibrin sealant or diathermy haemostasis. Other pain variables were controlled. Pain was measured by a visual linear analogue scale and inter-incisor distance on both the day of operation and the first post-operative day. The patients and pain measurer were blind to the randomization. The results showed that tonsillectomy with fibrin sealant haemostasis was significantly (P < 0.05) less painful than that with diathermy on both days studied and by both methods of pain measurement     

Delayed pain response after lumbar discography

Summary The delayed onset of symptomatic pain following lumbar discography (with no immediate pain response) is described in six patients, five with a minimum 2-year follow-up. It is usually seen in patients with nearly normal disc morphology who have incomplete or discrete annular tears that are not filled at the time of injection. Later (2–12 h in this study), dye leakage occurs through these lesions, thereby precipitating the discogenic pain This phenomenon may be missed and is probably more common than previously believed due to early discharge from the hospital, the patient expecting discomfort after the invasive study (hence no complaint is made), and the clinician being unaware of this delayed symptom, thereby not asking about it in follow-up. Close patient questioning regarding a delayed onset of symptomatic pain after discography is, therefore, an essential element in diagnostic information following this study.     

Personal history,training, and worksite as predictors of back pain of nurses

Back pain among nurses is a common problem. Prior studies of this problem have been based on cross-sectional or retrospective data. This 18-month prospective study involving nurses newly graduated from nursing school investigated personal, worksite, and training factors associated with future risk of back pain. Each nurse underwent a preliminary interview and periodic follow-ups to identify those with back injuries. Contingency tables and logistic regression analyses demonstrated that prior significant back pain episodes (evidenced by previous job changes because of back pain, frequent medication use, etc.) were associated with increased future risk. Training at nursing school or on the job did not have a protective effect. This pilot study therefore suggests factors useful in placement and counseling of new nurses and indicates the need for further implementation of mechanical lift assist device use. © 1994 Wiley-Liss, Inc.     

Substance P-like immunoreactivity in human cerebrospinal fluid

In a study to elucidate molecular mechanisms in pain, substance P-like immunoreactivity (SP-LI) was measured in lumbar CSF from 75 patients with lower back pain. Two samples – one before and one after lidocaine treatment – were obtained from each patient, and total SP-LI was measured in unfractionated (no HPLC) samples. SP-LI data were separated into three categories: placebo responders, pharmacological responders, and pharmacological non-responders. A significant difference was observed between the total SP-LI measurement of first and second samples of pharmacological non-responders. Distribution of SP-LI immunoreactive molecular species in two CSF patient samples (no ODS) was analyzed with a combination of reversed phase (RP) HPLC and RIA. Immunoreactivity in collected HPLC fractions was measured at calibrated retention times of synthetic SP-sulfoxide (SP-O), SP, and SP_5–11. Qualitative and quantitative differences in those HPLC-RIA metabolic profiles were observed within and between those two patients' samples. These data indicate that the type and amount of SP metabolism and SP precursor-processing differs in CSF between these two representative patients and within the short amount of time elapsed between acquiring these two samples.     

Abdominal ultrasonography in the diagnostic work-up in children with recurrent abdominal pain

We report on our experience with routine abdominal ultrasonography in 120 children (aged 3–15 years) with recurrent abdominal pain, in order to determine the diagnostic value of this investigation. Eight children (7%) revealed sonographic abnormalities: gallbladder stone (n = 2), splenomegaly (n = 1) and urogenital abnormalities (n = 5). The recurrent abdominal pain could be explained by these findings in only two (may be three) cases. Conclusion The diagnostic value of abdominal ultra‐sonography in unselected children with recurrent abdominal pain is low. However, the direct visualization of the abdominal structures as being normal may be helpful to the parents and the child in their understanding and acceptance of the benign nature of recurrent abdominal pain.
